Definitions
- the invention relates generally to containers. More specifically, the invention is a container apparatus (the “container”), a method for using containers, and a method of manufacturing containers.
- containers examples include cups for hot beverages (such as coffee, hot chocolate, tea, etc.), cups for non-heated beverages (such as milk, juice, water, soda, etc.), containers for food products (such as ice cream, soup, yogurt, solid foods, etc.), and containers for non-food or beverage products (such as office suppliers, medical devices, etc.).
- cups for hot beverages such as coffee, hot chocolate, tea, etc.
- cups for non-heated beverages such as milk, juice, water, soda, etc.
- containers for food products such as ice cream, soup, yogurt, solid foods, etc.
- containers for non-food or beverage products such as office suppliers, medical devices, etc.
- Containers are an important part of the modern economy. Many products cannot be stored, transported, sold, and/or used without first being secured in some type of container. Some types of products, such as many types of food products and virtually all beverage products, require some type of container for the product to be handled or consumed. In many contexts, the container is an integral part of how users “experience” the contents of the container. For example, in drinking a beverage, a human being often positions the beverage by positioning the cup that contains the beverage. Containers can also contribute to environmental waste after their utility has ended.
- Containers can be used to (1) protect the contained product; (2) protect users in utilizing the product; (3) facilitate the ability of users to experience the product; (4) shape the way users experience a product; (5) impact the ways in which users view the product; and (6) combinations of (1)-(5) above.
- the container serves to prevent the inadvertent disbursement of the coffee and in doing so prevents hot coffee from being spilled on the user.
- a container for a beverage product will typically need to be watertight while a container used for storing office supplies need not be watertight or even fully enclosable.
- a container suitable for use in the context of sterilized medical supplies will have different attributes than a container used to store spare change or golf tees.
- Even relatively similar types of products can involve different types of containers. For example, at a quick service food restaurant, different types of cups are used to hold juice, milk, coffee, and soda because of the different attributes that pertain to those products. Different beverages have different attributes, and those different attributes can merit containers possessing different attributes.
- a container used in restaurants will need to be suitable for use by individual consumers, a wide cross section of the population that includes persons with disabilities as well as individuals of below average physical and mental capabilities.
- a container used by locksmiths or mechanics to store their tools can utilize far more complex designs and operating procedures.
- the intended lifespan of a container can be a significant variable in the selection and design of a container. Many containers are disposed of after a single use. For example, a cup of ice cream sold in a grocery store or drug store is intended to be thrown away after the contents are consumed by a consumer. In contrast, a thermos can be emptied and filled over a lifetime of years or even decades.
- Disposable containers can raise substantial environmental issues if the containers, or even just portions of the container, are not biodegradable. Many such containers end up as litter that is both an eyesore and damaging to the environment.
- the “Great Pacific Garbage Patch” (which is also often referred to as the “Pacific Trash Vortex”) is made up of high concentrations of plastics and other debris trapped by the currents of the North Pacific Gyre. Whether or not the size of the Pacific Trash Vortex is currently as large as the state of Texas, there is no disputing the fact that the area is large and that the damage to that area is significant. Moreover, there are four other large places in the world's oceans where winds trap floating debris.
- Plastic lids for a paper cups and plastic water bottles exist far longer as waste than they do as useful consumer articles.
- a consumer typically enjoys a cup of coffee in a sitting lasting between 20 and 30 minutes. That lid can require years, decades, or even centuries to fully decompose.
- the invention relates generally to containers. More specifically, the invention is a container apparatus (the “container”), a method for using a container, and a method of manufacturing the container.
- the container can be implemented in a wide variety of different embodiments for use with a wide variety of different contents in a wide variety of different operational contexts.
- Examples of containers include cups for hot and not-hot beverages (coffee, milk, juice, water, soda, etc.), containers for food products (ice cream, soup, yogurt, solid foods, etc.), and containers for non-food or beverage products (office suppliers, medical devices, etc.).
- Different embodiments can be adapted to contain different types of products and user experiences.
- Different embodiments can utilize a wide range of different materials. Some embodiments of the container can be reusable while others are designed to be disposable. Many disposable embodiments of the container will include paperboard as one of the materials.
- the container includes a body and an attached lid.
- the body and lid are intended to be permanently attached to each other.
- the lid can be configured in such a manner as to be removable.
- the container is intended to allow for users to open and/or close the container as opposed to merely access the contents of the container while the container is in a closed state.
- Different embodiments of the container can have different operating states or positions.
- the container can include a plate located between the body and the lid can be used to facilitate the opening and/or closing of the lid.
- Some embodiments of the container will have one hinge while other embodiments of the container will have two hinges to facilitate the opening and closing of the lid.
- the containers described herein can be manufactured through the use of machine tools that are available in the prior art. No significant changes are required “beneath the table” of the various prior art machine tools, with some reconfigurations being made to tools above the table.
- the techniques that can be used to mass produce the container can be utilized to manufacture other articles, and are particularly useful in the context of manufacturing paperboard-related products.

In many embodiments, such materials are applied exclusively to the exterior surfaces of the container 20 so that the beverage in the container 20 does not come into contact with those materials.
- the container 20 also includes two flaps 54 , one on each side of the plate 24 .
- Non-aseptic embodiments of the container 20 that are curved or are even substantially cylindrical in shape (such as a cup) may benefit from having curved side score lines 55 between the plate 24 and flaps 54 , and a curved body hinge 56 .
- the non-aseptic container 20 illustrated in FIG. 1 a can be implemented in both disposable and non-disposable embodiments. Whether or not a particular embodiment is disposable will be primarily impacted by the material composition of the container 20 . Different embodiments of the container 20 can include many elements not illustrated in FIG. 1 a that are discussed below and illustrated in subsequent figures.
- FIG. 1 b is a diagram illustrating an example of a rear plan view of an open container 20 that does not include a plate 24 .
- the container 20 can be implemented to function as an aseptic container 20 for beverage products.
- beverages requiring aseptic containers 20 are milk and juice.
- Many disposable aseptic containers in the prior art as well as the aseptic container 20 of FIG. 1 b are configured to be filled before it is aseptically sealed.
- the container 20 of FIG. 1 b is not necessarily intended to be opened and closed repeatedly as the container 20 of FIG. 1 a is configured to function.
- the container 20 of FIG. 1 b need not include a plate 24 or a plate hinge 26 .
- FIG. 1 b discloses a flange 59 to aseptically seal the contents of the container 20 .
- the flange 59 will include score lines that bisect the edge of the flange. In other embodiments, there the flange 59 can include differently oriented score lines or no score lines whatsoever. The functionality of the flange 59 can be assisted by incrementally reducing the amount of material in the flange 59 as edge of the flange is approached.
- the aseptic container 20 of FIG. 1 b will typically require different materials than the non-aseptic container 20 of FIG. 1 a .
- Aseptic containers 20 will be comprised of combinations of paperboard, aluminum foil, metalized film, ethylene acrylic acid, low-density polyethylene, nylon, polystyrene, polyvinylidine chloride, ethylene vinyl alcohol, and/or other suitable materials.
- the method of manufacturing an aseptic container 20 will also differ from the method used to manufacture a non-aseptic container 20 .
- Aseptic containers 20 involve sterilization steps as various points in the process.
- the container 20 illustrated in FIG. 1 b is intended primarily for disposable use. However, depending on the materials use, the container 20 can be implemented to support reusable use. Such embodiments will need to use a sealing mechanism different than the flange 59 illustrated in FIG. 1 b . Different embodiments of the container 20 can include many elements not illustrated in FIG. 1 b that are discussed below and illustrated in subsequent figures.
- FIG. 1 c is a diagram illustrating an example of a rear plan view of a rectangular container 20 that includes a plate 24 .
- the container 20 is not limited to beverage products or even to products which are intended to be ingested or imbibed by human beings or other forms of living beings. Different embodiments of the container 20 can involve vastly different shapes, sizes, and materials. As illustrated in FIG. 1 c , such containers 20 can have lid 28 attached to a plate 24 that is attached to a body 22 . The parameters of the plate 24 are outlined by the body hinge 56 and the plate hinge 26 .
- Different containers 20 can involve different methods of use and be manufacturing using different manufacturing processes.
- a container 20 can be defined with respect to a variety of different attributes. Some of those attributes are discussed below.
- a container 20 can be used for the storage, transportation, and/or use of a wide variety of different products.
- a container 20 can be used to store a wide range of different food products and beverages, paper money and coins, office supplies, electronics components, tools, chemical products, cleaning detergents, fabric softeners, animals, and virtually anything else for the purposes of containment, storage, and/or transportation. Virtually any type or combination of solid, liquid, or even in certain circumstances, gas product can benefit from the use of a container 20 .
- Some types of contents must be removed from a container to be accessible to the user of the contained item while in other instances such as with many liquid products, the container 20 is the means by which a user controls the contents of the container 20 .
- the configuration of a particular container 20 will depend on the intended contents of that container 20 .
- some embodiments of the container 20 can be configured for the purposes of storing beverages, food products, medicinal products, or other items intended to be ingested by a human being or other living being.
- a container 20 for ingested items will have different operating requirements than a container 20 for non-ingested items.
- Some containers 20 may need to store hot liquids such as coffee while other embodiments may need to store cold solids such as ice cream as well as cold liquids such as melted ice cream.
- the contents of a container 20 must be kept dry while in other embodiments the contents of the container 20 are damp or even inherently wet.
- Different embodiments of the container 20 can have widely different shapes.
- a variety of different factors can individually or in combination with other factors impact the shape of the container 20 .
- Examples of potential factors can include but are not limited to the contents of the container 20 , ease of use, material composition of the container 20 , operating requirements of the container 20 , cost concerns, user expectations, durability requirements, transportation issues (including the ability to be effectively stacked), durability, and manufacturing constraints.
- the container 20 is likely to be cylindrical in shape or at least substantially cylindrical in shape as is illustrated in FIGS. 1 a and 1 b .
- a rectangular box shape as illustrated in FIG. 1 c is the most desirable shape.
- many embodiments of cup containers 20 will be substantially cylindrical in shape rather than cylindrical in shape because the bottom portion of the container 20 will be slightly smaller than the upper portions of the container 20 . This is to facilitate the ability to stack such containers 20 while they are in open and unfilled states.
- the shape of the container 20 can also be impacted by the operating state of the container 20 .
- many embodiments of the container 20 will have a circular or substantially circular horizontal cross-sectional shape when the container 20 is an a fully open position, i.e. when the lid 28 is fully upright as illustrated in FIGS. 1 a , 1 b , and 1 c .
- the shape of such a container 20 when in a closed or partially closed state can become less circular and more elliptical in shape.
- the change in shape results from the motion of the lid 28 , the plate 24 , and portions of the body 22 in the opening and closing of the container 20 .
- the doubled hinged architecture (see elements 26 and 56 ) of a container 20 is complicated by the curved shape of the container 20 . Most examples of hinges in the prior art involve straight hinges.
- the shape of the container 20 and the shape of the internal cavity 46 of the container 20 will mirror each other.
- the internal cavity 46 will often be substantially cylindrical in shape.
- the geometry of one or more cavities 46 within the container 20 can have a substantially different geometric shape than the container 20 .
- the container 20 can be implemented in ways that are consistent with ongoing non-disposable use, but many embodiments of the container 20 will be configured for disposable embodiments.
- the desired lifespan of a container 20 can also be influenced by the intended lifespan of the contents of the container 20 and the typical context of when a container 20 is loaded with its contents.
- the cup in FIG. 1 a is intended for use in an environment where the cup is filled by the user of the cup (or a service provider serving the user). This is the typical context for soft drinks, coffee, tea, and other drinks.
- the cup in FIG. 1 b is an aseptic container 20 that is filled and sealed prior to being distributed for consumption by users.
- the innovative aspects of the container 20 may be most beneficial in the context of disposable containers 20 because disposable containers 20 raise the most significant environmental concerns due to the sheer number of such containers 20 . For example, the number of disposable cups used and discarded each day is truly staggering. The high volume of such containers 20 coupled with the disposable nature of disposable containers also serves to make them extremely cost sensitive components in an efficient supply chain.
- Different embodiments of the container 20 can be comprised of a wide variety of different materials.
- the container 20 was originally designed for use in the context of paper or paperboard disposable cups.
- different materials can be used
- the cup could be comprised of paper, paperboard, stainless steel, metal, ceramics, plastics, or other types of materials.
- Different types of coatings such as polymer coatings, high barrier polymer coatings (including but not limited to high carrier silver coatings), polyethylene coatings (including but not limited to polyethylene terephthalate coatings), biopolymer coatings (including but not limited to polylactide polymers), biodegradable polyester, and other types of coatings can be used with respect to the container 20 .
- Any of the materials discussed above with respect to aseptic containers 20 can also be used to reinforce the structure of a container 20 that is not aseptically sealed.
- the container 20 will be primarily comprised of paperboard or some similar material, but particular portions of the container 20 may be reinforced with one or more coatings.
- Different material compositions for containers 20 can influence the different ways in which the different aspects of the containers 20 are shaped. For example, embossing (raising the material), debossing (recessing the material), stamping, folding, and cutting can be used to machine a container 20 comprised of paper, paperboard, or other materials.
- embossing raising the material
- debossing residual the material
- stamping folding, and cutting
- Such structural attributes can be critical to the functionality of the container 20 , but such attributes can also be very much constrained by the manufacturing constraints involved in implementing certain design features.
- lids are not typically biodegradable and they require significant quantities of oil for their production. Such lids are used once, often for mere hours or even minutes, and then spend decades in landfills or as floating debris in the ocean.
- the container 20 can be implemented in such a way as to be just as reliable as prior art containers, while being less expensive and less environmentally damaging at the same time.
- the material composition and attributes of the container 20 can also be impacted by requirements relating to thermal insulation
- Different containers 20 may involve vastly different operating parameters relating to temperature. Coffee and soup are served hot, while ice cream and frozen yogurt are served cold. The temperature of the contents within the container 20 can impact the lifespan of the container 20 as well as the ability of the container 20 to satisfy the needs its users.
- Some embodiments of the container 20 will include dimples 31 or even dimple groups 33 to insulate the user of the container 20 from the temperature of the contents of the container 20 .
- Dimples 31 can extrude outwards toward the external environment of the container, inward towards the cavity 46 of the container, or in both directions.
- Dimples 31 and dimple groups 33 serve can serve as a built in “sleeve” for coffee drinkers who would otherwise require an additional separate sleeve in order to enjoy their beverage. Sleeves could also me manufactured to include such dimples 31 and dimple groups 33 .
- the heat-flow attributes of a container 20 can also be impacted through the use of multiple-wall 42 configurations, the ventilation of the container 20 , and the material composition of the container 20 .
- Different containers can have different air flow requirements.
- the same container 20 may have different requirements in different contexts. For example, while an aseptic container 20 containing juice or milk is closed and sealed, it should be essentially air tight for sanitation reasons. However, in the drinking a beverage from a container 20 , there are ventilation and pressurization requirements to allow the beverage to flow out of the container 20 consistent with user expectations.
- a cover 27 shaped in such a manner to allow a beverage product to be ventilated immediately prior to being imbibed by the user, preventing the user from being injured by a drink that is too hot to safely consume.
- a rim 34 with a serrated edge can also enhance the ventilation of the container 20 and its contents.
- the core surfaces 75 of the container 20 can include a body 22 , a lid 28 , and a plate 24 that serves as an interface between the body 22 and the lid 28 . Many of the boundaries between these different surfaces 75 are marked by score lines 75 .
- all or substantially all of the components of the container 20 are integral with the container 20 and are not designed to be removable from the container 20 .
- What distinguishes the boundaries of different components or surfaces 75 in such embodiments can include: geometric shapes and dimensions; relative positions within the container 20 ; function; relative movement capabilities; and embosses, debosses, score lines, and other types of folds, grooves, cuts, serrations, etc, (collectively “score lines”).
- Score lines 70 can be divided into two categories.
- a foldable score line 71 is a score line that bends or folds to facilitate the movement of the lid 28 .
- a non-foldable score lines 72 is a score line that reinforces the structural integrity of a particular surface.
- a plate hinge 26 acts as a hinge between the lid 28 and the plate 24 and a body hinge 56 acts as a hinge between the plate 24 and the body 22 .
- the container 20 utilizes a double-hinged architecture with two foldable score lines 71 serving as two hinges that surround the plate 24 .
- the body hinge 56 , plate hinge 26 , side score line 55 , and flap bottom score line 57 are each examples of foldable score lines 71 because they are intended to be bent or folded to facilitate the opening and closing of the lid 28 .
- Examples of non-foldable score lines 72 are discussed below, such as a vertical crease 25 , a support score line 38 , a tab base score line 48 , a cover score line 60 , and a stiffener score line 63 ,
- the container 20 can be implemented in a wide variety of different component configurations.
- the container 20 includes a body 22 , a lid 28 , and a body hinge 56 . All other components of the container 20 are optional, depending on the particular embodiment.
- the body 22 and the lid 22 are intended to be permanently integral with each other. In other embodiments, the user 20 may have the option of either temporarily or permanently removing the lid 22 .
- FIGS. 1 a and 1 c Many embodiments of the container 20 (see FIGS. 1 a and 1 c ) will also include a plate 24 that serves as an interface between the lid 28 and the body 22 . Many of embodiments of the container 20 (see FIGS. 1 a and 1 b ) will include flaps 54 located near the base of the lid 28 that assist the user to seal the lid 28 in a closed position.
- Embodiments of the container 20 that are configured to be filled and sealed prior to being provided to users can include a flange 59 that is used to seal the container.
- a container 20 not designed to be filled by users can include both a plate 24 and a flange 59 .
- Containers 20 serve to selectively contain and selectively make accessible the contents of the container 20 .
- Different containers 20 will have different operating states, different openings being capable of open or closed, and different components that will involved in transitioning from one operating state to another.
- the container 20 has a lid 28 for opening and closing the container 20 .
- each container 20 will have at least two or more operating states.
- the plate 24 , flaps 54 , tab(s) 30 , passageway(s) 32 , and potentially other components can individually possess operating states that transition from open to closed or closed to open as the container 20 as a whole transitions from an operating state of a fully opened state to a fully closed state, and vice versa.
- FIG. 2 a is a diagram illustrating an example of an elevated rear view of a container 20 in a fully closed state.
- the lid 28 is secured within an inner groove 52 in the body 22 , the opening 32 is blocked by the tab 30 , and the plate 24 and flaps 54 are in fully closed positions.
- FIG. 2 b is a diagram illustrating an example of an elevated rear perspective view of a container 20 in a fully closed state except for an open tab passageway 32 .
- the passageway 32 (which can also be referred to as an opening 32 ) allows a user to access the contents of the container 22 while the lid 28 is still in a sealed position.
- the passageway 32 can be used to insert a straw, or the user can cause the contents to pour out the passageway 32 .
- a horizontal cross section of the body 22 in FIG. 2 b is substantially more elliptical in shape than the illustrating in FIG. 2 c.
- FIG. 2 c is a diagram illustrating an example of an elevated rear view of a container 20 in a partially open and partially closed state.
- the lid 28 is no longer secured within the inner groove 52 , and the flaps 54 and plate 24 are neither substantially parallel with a bottom surface 40 of the container 20 nor substantially straight up as when in a fully opened operating state.
- a horizontal cross section of the body 22 in FIG. 2 c is substantially more elliptical in shape than the illustrating in FIG. 2 d.
- FIG. 2 d is a diagram illustrating an example of an elevated rear view of a container 20 in a fully open state, such as the containers in FIGS. 1 a , 1 b , and 1 c .
- a horizontal cross section of the body 22 in FIG. 2 d is substantially circular in shape or at least substantially more circular in shape in comparison to the container in FIG. 2 b or even FIG. 2 c.
- FIGS. 8 a - 8 c discloses similar states from a different view.
- FIGS. 8 a - 8 c are discussed below.
- the container 20 can involve a variety of different methods for opening and closing the container 20 . Moreover, as identified above and illustrated in FIGS. 2 a through 2 d , the container 20 can possess more than two operating states. Different components within the container 20 are capable of having opened, closed, or partially opened/partially closed individual operating states.
- FIG. 3 a is a flow chart diagram illustrating an example of a method for opening a container 20 .
- the edge 51 of the lid 28 is dislodged from the inner groove 52 of the body 22 .
- the process at 200 is analogous to the differences between FIG. 2 b and FIG. 2 c discussed above.
- the process unseals the container 20 and permits the various components to move as they are configured to move.
- the plate 24 and flaps 54 flex.
- the process at 202 is illustrated by the differences between FIGS. 2 b and 2 d.
- the lid 28 is lifted into a straight up position as illustrated in FIGS. 1 a , 1 b , 1 c , and 2 d.
- the loading or filling to the container 20 could occur while in potentially any of the states identified above.
- the closing/sealing process ends after the closing of the opening 32 .
- FIG. 3 b is a flow chart diagram illustrating an example of a method for closing a container 20 .
- the process of FIG. 3 b can be characterized as the process of FIG. 3 a , except in reverse.
- the plate 24 and flaps 54 are flexed while the lid 28 remains substantially upright.
- the lid 28 is pressed downward.
- the edge 51 of the lid 28 is secured within the inner groove 52 of the body 22 .
- Different users may close the container 20 applying pressure in different ways. For example, users could press down on the lid 28 or the plate 24 to initiate the closing process.
- Different embodiments of the container 20 can utilize different manufacturing processes and different combinations of tooling.
- a single design of a container 20 can be manufactured in a variety of different ways.
- the process of manufacturing the container 20 involves creating blanks, flat two dimensional cutouts that are subsequently shaped and treated to ultimately form the container 20 .
- Certain score lines, coatings, and other processing may be performed on a blank, while other processing can be performed after one or more blanks have been combined and shaped.
- FIG. 4 a is a flow chart diagram illustrating an example of a method for manufacturing a container 20 from two blanks.
- FIG. 5 a is a diagram illustrating an example a top blank 100 and
- FIG. 5 b is a diagram illustrating an example of bottom blank 102 .
- a bottom blank 100 and a top blank 102 are created.
- the bottom blank 100 is fused together with the top blank 102 as the container 20 is shaped into a cup.
- all score lines except for the inner groove 52 and body hinge 56 are implemented prior to the securing of the top blank 102 to the bottom blank 100 .
- all score lines can be added as part of the blank preparation process that occurs prior to combining the blanks.
- the body hinge 56 can be implemented in the shape of a substantially curved arc rather than a straight line segment.
- a contrast of FIG. 7 a with FIG. 7 b illustrates this difference.
- the curved body hinge 56 coupled with the inner groove 52 together form a single score line 61 that encircles all or substantially all of a horizontal cross section of the body 22 .
- the body hinge 56 is straight, impacting the overall shape of the score line 61 .
- a substantially circular combination loop 61 as illustrated in FIG. 7 a (in contrast to the ends of a substantially circular inner groove 52 mating with the ends of a substantially straight body hinge 56 as illustrated in FIG. 7 b ) make the container 20 more circular in shape when the container 20 is in a fully opened state.
- This has useful features in terms of stackability and durability.
- the fact that such an implementation involves a circular or substantially circular body hinge 56 is a result that is not taught in the prior art, and is counterintuitive to those of ordinary or even superior skill in the applicable art.
- the flexural strength and crush resistance of the container 20 is enhanced as a result of the top to bottom compression strength.
- Various processing can be used to enhance the combination loop 61 and further strengthen the overall structure of the container 20 .
- the container 20 can be manufactured using a two blank configuration as described above, there are advantages to using a three blank configuration in which the loop 61 is machined into the container 20 after a lid blank 104 and a sidewall blank 106 are fused together, and then shaped around the bottom blank 100 .
- the three blank configuration of FIG. 4 b can also involve machining the primary score line 61 comprising the body hinge 56 and the primary groove 52 after the container 20 has been shaped into a substantially cylindrical shape.
- all score lines can be machined into the blanks prior to the process of fusing them together.
- FIG. 5 c is a diagram illustrating an example of a lid blank 104 used in the process illustrated by FIG. 4 b .
- FIG. 5 d is a diagram illustrating an example of a sidewall blank 106 used in the process illustrated by FIG. 4 b .
- Different embodiments of the container 20 can involve different component configurations with many of those differences manifesting themselves in the blanks used to make the containers 20 .
- FIG. 5 c discloses vertical creases 25 to reinforce the lid 28 of the container 20 .
- a reinforcement member 23 is used to connect the lid blank 104 with the plate 24 of the sidewall blank 106 , strengthening the container 20 as the container 20 is transitioned between open, semi-open/semi-closed, and closed operating states.
- FIG. 5 c also illustrates a cover 27 that is different than a tab 30 .
- Other features that may be highly desirable are the curved side flaps 55 and a flap angle 97 of between about 35 degrees and about 70 degrees.
- FIG. 4 b There are several advantages to the 3 blank manufacturing process of FIG. 4 b over the 2 blank manufacturing process of FIG. 4 a .
- the process disclosed in FIG. 4 b can prevent lid staining and wicking.
- the lid 28 can be better protected against humidity. Costs and waste is reduced by reducing the amount of scrap paper board that results because a three blank configuration requires fewer sheets of paperboard than a two blank configuration.
- FIG. 4 b is a flow chart diagram illustrating an example of a method for manufacturing a container 20 utilizing 3 blanks.
- a sidewall blank 106 and a lid blank 104 are prepared.
- the sidewall blank 106 and the lid blank 104 are fused together into a fused blank.
- a bottom blank 100 is prepared.
- the fused blank is shaped into a shell around the bottom blank 100 .
- the bottom blank 100 is secured within the bottom portion of the shaped shell.
- the process of machining the score line 61 that comprises the body hinge 56 and the inner groove 52 can be implemented at potentially any time after the lid blank 104 and the sidewall blank 106 are combined and shaped into the shape of the container 20 .
- the shaping of the fused blank typically happens in conjunction with insertion of the bottom blank 100 .
- the manufacturing process is described in greater detail below,
- the container 20 of FIG. 2A can be manufactured on a mass production and cost effective basis using substantially unmodified prior art machine tools. Utilizing the infrastructure provided below the table of such tools, the desired modifications can be made to functionality provided above the table. The ability to utilize prior art tools is a significant advantage in terms of market penetration and the costs associated with the production of containers 20 .
- containers 20 are used primarily with respect to the contents-related (i.e. product-related) functionality, containers 20 can be implemented in ways to serve additional functions.
- Containers 20 can provide an excellent opportunity for businesses and other organizations to facilitate communications.
- the container 20 can include text, graphics, and other indicia to communicate brand identity, product information, marketing information, or public service announcements.
- some containers 20 can be configured to provide audio communications using technology similar to that used to play music when someone opens a greeting card.
- a container 20 can also be configured to use powered electronics to flash lights or otherwise generate visual indicia.
- a coffee cup 20 container could be configured to play a song, flash a light, and/or generate some other response upon the opening or closing of the lid.
- Containers 20 can also utilize connectivity and communication technologies such as RFID technology to track the movement and usage of the container 20 .
- Such configurations may involve specific compartments within the container 20 for hosting the ancillary/supplemental component.
- a multiple body wall structure could include a cap within the wall to contain the particular component.
- a specific compartment is shaped in the applicable location within the container 20 for use of the ancillary/supplemental component.
- Disposable cups are extremely high volume commodities that are subject to significant cost constraints and relatively high functional reliability requirements. When cost constraints and reliability requirements are coupled with intrinsic manufacturing limitations, it is easy to see why the conventional disposable cup has not changed much over the years. For example, to the extent that some individuals may have sought to design a paper cup with an attached lid not comprised of plastic, such designs were at best too expensive to manufacture or insufficiently reliable for consumer use. At worst, such approaches could actually be impossible to mass produce effectively.
- the prior art teaches away from the container 20 in part because of cost constraints, functionality requirements, manufacturing constraints, etc. have collectively left those of ordinary skill in the prior art into an intellectual dead end with respect to the design of containers, particularly in the context of disposable containers.
- FIG. 2 a is a diagram illustrating an example of an elevated rear view of a container 20 in a fully closed state.
- the container 20 illustrated in FIG. 2 a is a cup that can be machined from and/or into a single piece of paper, paperboard, or similar material. Different ways to manufacture the container 20 are described in detail below.
- Each embodiment of the container 20 can involve different types of products, different material compositions, and different manufacturing processes.
- Each embodiment of the container 20 will include a container body (the “body”) 22 and a lid 28 .
- Some containers 20 can include more than one body 22 and/or more than one lid 28 .
- the body 22 and lid 28 can be implemented in a wide variety of different shapes and sizes using different materials and coatings.
- the container 20 will also include a body hinge 56 . All other components in the various Figures are optional and need not be included in all embodiments of the container 20 .
- Most embodiments of the container 20 will include a plate 24 that is connected to both the lid 28 and to the body 22 , with one end of the plate 24 being connected to the lid 28 and the other end of the plate being connected to the body 22 .
- Embodiments that include a plate 24 will typically include a plate hinge 26 and flaps 54 , although the presence of flaps 54 does not necessitate the presence of the plate 24 .
- the lid 28 and even the plate 24 can be configured to be removable from the container 20 , such as through perforated edges to a paperboard or other material that can be removed by hand.
- the body 22 , lid 28 , and plate 24 are integral to each other and are not configured to be intentionally separable from each other.
- the body 22 of the container 20 typically constitutes the majority of the surface area of the container 22 .
- the body 22 of the container 20 also typically defines the shape, size, and contours of the container 20 .
- the container 20 is a cup that is substantially cylindrical in shape.
- the shape of the container 20 in FIG. 2 d is the result of a substantially cylindrical body 22 .
- the body 22 of the container 20 may include various score lines for the purposes of reinforcing the structural strength and integrity of the container 20 as well as functions such as sealing the lid 28 in a closed position.
- the shape of the container 20 can be significantly less cylindrical when the container 20 is a fully closed position.
- Various figures can be contrasted to visualize this attributes.
- the containers 20 a stack of containers 20 illustrated in FIG. 9 b are in a fully open state and thus substantially cylindrical in shape (which facilitates better stacking capabilities) while the overall shape of the containers 20 stacked in FIG. 9 a are substantially more elliptical in shape.
- the difference being that the curved hinge 56 in the open position of FIGS. 9 b and 9 c is substantially straight when the container 20 is the closed position of FIG. 9 a.
- the body 22 is designed to be the least impacted by the transition of the container 20 from one state to another. Many portions of the body 22 such as the bottom surface or base 40 of the body 22 are totally unaffected by transitions in operating states. However, the portion of the body immediately underneath the body hinge 56 can be significantly impacted by the transition of the container from a fully opened to a fully closed state, or vice versa.
- FIG. 7 f the body 22 when the container 22 is in a fully open state
- FIG. 7 g the body 22 when the container 22 is in a fully closed state
- the bottom portion of the body 22 typically serves as the base 40 of the container 20 with the lid 28 being placed in a vertical position that is higher than most or even all of the body 22 , depending on the particular embodiment of the container 22 and the particular operating state of the lid 28 .
- the uppermost portion of a tab 30 (which can extend off of and be part of the lid 28 ) represents the highest vertical point on the container 20 in a conventional orientation of the container 20 when the container 20 is in a fully closed operating configuration/state.
- the lowest vertical portion of the container 20 illustrated in FIG. 2 a is a base surface 40 of the body 22 upon which the container 20 sits when placed on a substantially flat surface such as a table.
- the relative vertical directions of up and down, as well as the perspective of relative horizontal attributes versus relative vertical attributes are discussed from the perspective of a container 20 supported by the base 40 on a substantially flat surface.
- the body 22 will be comprised primarily of paper or paperboard. Different embodiments of the container 20 may require additional linings, additional material, or entirely different material.
- polyethylene can be used to reinforce certain portions of the body 22 or can be used to comprise the entire body 22 .

- the cavity 46 of the body 22 is shaped by the material surrounding the cavity 46 which can be referred to as a wall 42 .
- the wall 42 will often be similarly shaped.
- Some embodiments of the container 20 can involve single-layered wall architecture. Other embodiments may involve a framework involving two, three or more layers. For example, in some embodiments, a three layered approach involving two layers of material surrounding a layer of air can be used to comprise the walls 42 .
- Some attributes of the wall(s) 42 will be dependent upon manufacturing concerns. For example, in shaping a substantially cylindrical container 20 from a substantially flat blank or combination of blanks, an adhesive can be used to secure the shape of the cup. Temperature, pressure, folding, embossing, debossing, and other processes can also be used in shaping and securing the wall(s) 42 . Such processes will impact the attributes of the wall(s) 42 .
- the container 20 can be manufactured such that no adhesive is used on a portion of an interior surface 44 of a wall 42 . This prevents such an adhesive from coming into contact with the contents of the container 20 , which can be desirable in terms of complying with Food and Drug Administration (“FDA”) regulations.

- the body hinge 56 is substantially curved in shape (with a substantially circular loop 61 ) when the container 20 is in a fully open position and substantially straight in shape when the container 20 is in a fully closed position. In other embodiments, even an open state of the container 20 will involve a body hinge 56 that is substantially less circular.
- the shape of the body hinge 56 will often depend on the manufacturing process. If the body hinge 56 is machined into the blank prior to the fusing of the blanks together, the body hinge 56 will be substantially more straight than it otherwise would be. If in contrast, the primary score line 61 is machined after the blanks have been fused together and shaped, the body hinge 56 can be substantially circular when the container 20 is in a fully open state.
- the body hinge 56 is a score line.

- Examples of plate hinges 26 are illustrated in FIGS. 1 a , 1 c , 2 a - 2 d , and 6 d .
- FIG. 6 e illustrates an example of a plate hinge 26 that includes a hinge break 45 .
- Two side score lines 55 serve to connect the plate 24 from two exterior flaps 54 in embodiments of the container 20 that include the two flaps 54 .
- the side score lines 55 can be curved. Curved side score lines 55 can form a substantially circular arc 41 along with the lid 28 .
- the curved shape of the side score lines 55 can enhance a larger circular arc 41 and preserve a more circular or elliptical shape of the container 20 (if the container 20 is substantially circular or elliptical in shape in the first place) when the container 20 is in a closed position.
- the container 20 will include two flaps 54 , one to each side of the plate 24 , to facilitate the sealing of the container 20 in a closed position.

- the boundaries of the flaps 54 are often demarcated by substantially vertical 55 and substantially horizontal score lines 57 .
- one or more flaps 54 may be used to support and enhance the ability of the plate 24 to function as a hinge for the lid 28 .
- Some embodiments of the flaps 54 can be configured to be further twisted or pushed in by the user to further secure the lid 28 in a closed position. Such twisting or pushing in may render the container 20 undesirable for subsequent opening and refilling.
- An embodiment of the container 20 that uses a plate 24 need not include any flaps 54 , but a combination of one plate 24 with one flap 54 on each side is often desirable.

- Skid locks 58 can be implemented into the plate 24 using a wide variety of different manufacturing processes.
- skid locks 58 The ability of skid locks 58 to facilitate the stacking of closed containers 20 is illustrated in FIG. 9 a.
- some embodiments of the plate 24 may include a hinge break 45 .
- the hinge break 45 can facilitate the transition functionality of the plate hinge 26 .
- the hinge break 45 can also provide an opening in which the tab 30 can be pressed into when the tab 30 is in a fully opened position. For example, instead of the tab 30 point upwards in FIG. 2 b , the tab 30 could be pushed into the opening resulting from the hinge break 45 . It can provide a way to secure the tab 30 in a position that will prevent the tab 30 from interfering with the use of the container 20 while the container 20 is being used. For example, in an embodiment of the container 20 used for the purposes of storing and drinking beverages, the tab 30 can be secured in the hinge break 45 when the user is drinking from the container 20 .
- the hinge break 45 is a semi-circle cut out from the plate hinge 26 .

Abstract
A container apparatus is disclosed that can utilize a “buffer zone” between a highly moveable lid and a substantially stationary body. A collection of score lines substantially surrounding a plate can mediate between the mobile lid and stationary body. Flaps and accompanying side score lines can act collectively with the plate to facilitate the opening and closing of the lid. Opening and closing the lid can involve the folding of the various score lines in the buffer to various degrees.

No. 61/577,084) filed on Dec. 18, 2011; and (6) the provisional patent application titled “CONTAINER APPARATUS AND METHODS FOR USING AND MANUFACTURING THE SAME” (Ser. No. 61/664,130) filed on Jun. 25, 2012.
- The invention relates generally to containers. More specifically, the invention is a container apparatus (the “container”), a method for using containers, and a method of manufacturing containers.
- Examples of containers include cups for hot beverages (such as coffee, hot chocolate, tea, etc.), cups for non-heated beverages (such as milk, juice, water, soda, etc.), containers for food products (such as ice cream, soup, yogurt, solid foods, etc.), and containers for non-food or beverage products (such as office suppliers, medical devices, etc.).
- Containers are an important part of the modern economy. Many products cannot be stored, transported, sold, and/or used without first being secured in some type of container. Some types of products, such as many types of food products and virtually all beverage products, require some type of container for the product to be handled or consumed. In many contexts, the container is an integral part of how users “experience” the contents of the container. For example, in drinking a beverage, a human being often positions the beverage by positioning the cup that contains the beverage. Containers can also contribute to environmental waste after their utility has ended.
- Different types of products require different types of containers and different types of containers can have different purposes. Containers can be used to (1) protect the contained product; (2) protect users in utilizing the product; (3) facilitate the ability of users to experience the product; (4) shape the way users experience a product; (5) impact the ways in which users view the product; and (6) combinations of (1)-(5) above. In the context of a coffee cup, the container serves to prevent the inadvertent disbursement of the coffee and in doing so prevents hot coffee from being spilled on the user.
- In meeting the needs of users, it is important to consider the feedback loops between the contents of the container and the container itself. The attributes of a product will often impact the attributes of the container used to house the product, and vice versa. For example, a container for a beverage product will typically need to be watertight while a container used for storing office supplies need not be watertight or even fully enclosable. Similarly, a container suitable for use in the context of sterilized medical supplies will have different attributes than a container used to store spare change or golf tees. Even relatively similar types of products can involve different types of containers. For example, at a quick service food restaurant, different types of cups are used to hold juice, milk, coffee, and soda because of the different attributes that pertain to those products. Different beverages have different attributes, and those different attributes can merit containers possessing different attributes.
- Consumers have increasing expectations with regards to the usability and convenience of the containers that they interact with. Different containers can also have different anticipated users possessing different skill levels and even different physical capabilities. The proper usage of a container can vary widely depending on whether or not the anticipated user of the container is a consumer. For example, a beverage container used in restaurants will need to be suitable for use by individual consumers, a wide cross section of the population that includes persons with disabilities as well as individuals of below average physical and mental capabilities. In contrast, a container used by locksmiths or mechanics to store their tools can utilize far more complex designs and operating procedures.
- The intended lifespan of a container can be a significant variable in the selection and design of a container. Many containers are disposed of after a single use. For example, a cup of ice cream sold in a grocery store or drug store is intended to be thrown away after the contents are consumed by a consumer. In contrast, a thermos can be emptied and filled over a lifetime of years or even decades.
- Disposable containers can raise substantial environmental issues if the containers, or even just portions of the container, are not biodegradable. Many such containers end up as litter that is both an eyesore and damaging to the environment. For example, the “Great Pacific Garbage Patch” (which is also often referred to as the “Pacific Trash Vortex”) is made up of high concentrations of plastics and other debris trapped by the currents of the North Pacific Gyre. Whether or not the size of the Pacific Trash Vortex is currently as large as the state of Texas, there is no disputing the fact that the area is large and that the damage to that area is significant. Moreover, there are four other large places in the world's oceans where winds trap floating debris. Plastic lids for a paper cups and plastic water bottles exist far longer as waste than they do as useful consumer articles. A consumer typically enjoys a cup of coffee in a sitting lasting between 20 and 30 minutes. That lid can require years, decades, or even centuries to fully decompose.
- Billions of plastic bottles end in U.S. landfills each year. If those bottles are laid end-to-end, there are enough plastic bottles disposed of each year to circle the equator hundreds of times over or to reach the moon and back multiple times. As the population in developed countries grows and as less economically advanced nations grow economically, the environmental impact of disposable containers will only increase.
- Old habits die hard, and it is difficult to change the technical, business, and consumer expectations with regards to disposable containers. The business constraints on the manufacture of disposable containers such as paper cups are quite restrictive. The incremental cost per container must be minimized to the extreme while minimizing waste and satisfying quality requirements. The focus is on shaving costs, not in the making of fundamental design changes. The high volume and low margin aspects of container manufacture are coupled with expensive tooling and other startup costs. Potentially innovative designs are often too expensive to effectively manufacture. In many instances, innovative designs are literally impossible to manufacture on a mass-production basis. The aggregate incentives and constraints on manufacturers is a strong disincentive for product innovation. The underlying economics of such disposable containers coupled with manufacturing limitations affirmatively teach away from innovative container designs. Preconceived notions relating to disposable cups produced with paperboard further serve to stifle innovation by teaching away from potential advances.
- Consumer expectations also impede innovative changes to disposable containers. There are thousands of coffee shops and other retail outlets in the U.S. who collectively sell millions of coffee servings each year with paper or Styrofoam cups that utilize conventional plastics lids. It would be desirable for better containers to be used in conjunction with contained products. However, most purchasing decisions are based primarily on the product, not the container. This basic and simple truth has unfortunate ramifications because consumer demand not only fails to encourage innovation, but can also affirmatively impede substantial innovations in container design. It is no accident that the conventional paper cup has changed very little over the course of recent decades. Consumers are used to the way things are, and in many instances, consumers are oblivious to container-related attributes and their implications.
- The combined impact of design limitations, manufacturing constraints, and the economic reality of razor thin margins serve to lock in the status quo when it comes to the design of disposable containers. Many aspects of the various container configurations described below are counter-intuitive to those in the business of designing and making containers.
- In solving the problem of the plastic lid on disposable containers, a method of manufacture relating to paperboard-related products has been invented.
- The invention relates generally to containers. More specifically, the invention is a container apparatus (the “container”), a method for using a container, and a method of manufacturing the container.
- The container can be implemented in a wide variety of different embodiments for use with a wide variety of different contents in a wide variety of different operational contexts. Examples of containers include cups for hot and not-hot beverages (coffee, milk, juice, water, soda, etc.), containers for food products (ice cream, soup, yogurt, solid foods, etc.), and containers for non-food or beverage products (office suppliers, medical devices, etc.). Different embodiments can be adapted to contain different types of products and user experiences. Different embodiments can utilize a wide range of different materials. Some embodiments of the container can be reusable while others are designed to be disposable. Many disposable embodiments of the container will include paperboard as one of the materials.
- The container includes a body and an attached lid. In many embodiments of the container, the body and lid are intended to be permanently attached to each other. In other embodiments, the lid can be configured in such a manner as to be removable.
- Many embodiments of the container are intended to allow for users to open and/or close the container as opposed to merely access the contents of the container while the container is in a closed state. Different embodiments of the container can have different operating states or positions.
- Many embodiments of the container can include a plate located between the body and the lid can be used to facilitate the opening and/or closing of the lid. Some embodiments of the container will have one hinge while other embodiments of the container will have two hinges to facilitate the opening and closing of the lid.
- Despite the design and manufacturing preconceptions in the prior art, the containers described herein can be manufactured through the use of machine tools that are available in the prior art. No significant changes are required “beneath the table” of the various prior art machine tools, with some reconfigurations being made to tools above the table. The techniques that can be used to mass produce the container can be utilized to manufacture other articles, and are particularly useful in the context of manufacturing paperboard-related products.

FIGS. 1 a, 1 b, and 1 c illustrate examples of back plan views ofdifferent containers 20. InFIGS. 1 a, 1 b, and 1 c alid 28 is shown as attached to abody 22 of thecontainer 20 even while thecontainer 20 is in a fully open operating state. - The
container 20 can be implemented in a wide variety of different shapes and operating configurations. Different embodiments of thecontainer 20 can involve a wide variety of different components comprised of a wide variety of different materials. Different embodiments of thecontainer 20 are suited for different types of contents. -
FIG. 1 a is a diagram illustrating an example of rear plan view of anopen container 20 that includes aplate 24. Thecontainer 20 inFIG. 1 a is intended for use as a non-aseptic container for beverages such as coffee, water, soda, and other similar beverages. Thecontainer 20 includes abody 22, alid 28, and aplate 24 between thelid 28 and thebody 22. Theplate 24, along with thebody hinge 56 and plate hinge 26 serve to facilitate the transition of thecontainer 20 from a fully open operating state to a fully closed operating state. Anon-aseptic cup container 20 can be implemented in both disposable and non-disposable embodiments. A disposable embodiment of thecontainer 20 inFIG. 1 a can be comprised primarily of paperboard. Score lines, cuts, rolls, and other attributes can be implemented into thecontainer 20. Adhesives and coatings of non-paperboard materials can also be used to reinforce the structure of thecontainer 20. In many embodiments, such materials are applied exclusively to the exterior surfaces of thecontainer 20 so that the beverage in thecontainer 20 does not come into contact with those materials. As illustrated inFIG. 1 a, thecontainer 20 also includes twoflaps 54, one on each side of theplate 24. Non-aseptic embodiments of thecontainer 20 that are curved or are even substantially cylindrical in shape (such as a cup) may benefit from having curved side score lines 55 between theplate 24 and flaps 54, and acurved body hinge 56. - The
non-aseptic container 20 illustrated inFIG. 1 a can be implemented in both disposable and non-disposable embodiments. Whether or not a particular embodiment is disposable will be primarily impacted by the material composition of thecontainer 20. Different embodiments of thecontainer 20 can include many elements not illustrated inFIG. 1 a that are discussed below and illustrated in subsequent figures. -
FIG. 1 b is a diagram illustrating an example of a rear plan view of anopen container 20 that does not include aplate 24. - The
container 20 can be implemented to function as anaseptic container 20 for beverage products. Common examples of beverages requiringaseptic containers 20 are milk and juice. Many disposable aseptic containers in the prior art as well as theaseptic container 20 ofFIG. 1 b are configured to be filled before it is aseptically sealed. Thus, thecontainer 20 ofFIG. 1 b is not necessarily intended to be opened and closed repeatedly as thecontainer 20 ofFIG. 1 a is configured to function. As a result, thecontainer 20 ofFIG. 1 b need not include aplate 24 or aplate hinge 26. The other noticeable difference betweenFIG. 1 a andFIG. 1 b is thatFIG. 1 b discloses aflange 59 to aseptically seal the contents of thecontainer 20. In some embodiments, theflange 59 will include score lines that bisect the edge of the flange. In other embodiments, there theflange 59 can include differently oriented score lines or no score lines whatsoever. The functionality of theflange 59 can be assisted by incrementally reducing the amount of material in theflange 59 as edge of the flange is approached. - Although not visible from the drawings, the
aseptic container 20 ofFIG. 1 b will typically require different materials than thenon-aseptic container 20 ofFIG. 1 a.Aseptic containers 20 will be comprised of combinations of paperboard, aluminum foil, metalized film, ethylene acrylic acid, low-density polyethylene, nylon, polystyrene, polyvinylidine chloride, ethylene vinyl alcohol, and/or other suitable materials. The method of manufacturing anaseptic container 20 will also differ from the method used to manufacture anon-aseptic container 20.Aseptic containers 20 involve sterilization steps as various points in the process. - The
container 20 illustrated inFIG. 1 b is intended primarily for disposable use. However, depending on the materials use, thecontainer 20 can be implemented to support reusable use. Such embodiments will need to use a sealing mechanism different than theflange 59 illustrated inFIG. 1 b. Different embodiments of thecontainer 20 can include many elements not illustrated inFIG. 1 b that are discussed below and illustrated in subsequent figures. -
FIG. 1 c is a diagram illustrating an example of a rear plan view of arectangular container 20 that includes aplate 24. - The
container 20 is not limited to beverage products or even to products which are intended to be ingested or imbibed by human beings or other forms of living beings. Different embodiments of thecontainer 20 can involve vastly different shapes, sizes, and materials. As illustrated inFIG. 1 c,such containers 20 can havelid 28 attached to aplate 24 that is attached to abody 22. The parameters of theplate 24 are outlined by thebody hinge 56 and theplate hinge 26. -
Different containers 20 can involve different methods of use and be manufacturing using different manufacturing processes. - A
container 20 can be defined with respect to a variety of different attributes. Some of those attributes are discussed below. - Different embodiments of the
container 20 can be used for the storage, transportation, and/or use of a wide variety of different products. Acontainer 20 can be used to store a wide range of different food products and beverages, paper money and coins, office supplies, electronics components, tools, chemical products, cleaning detergents, fabric softeners, animals, and virtually anything else for the purposes of containment, storage, and/or transportation. Virtually any type or combination of solid, liquid, or even in certain circumstances, gas product can benefit from the use of acontainer 20. Some types of contents must be removed from a container to be accessible to the user of the contained item while in other instances such as with many liquid products, thecontainer 20 is the means by which a user controls the contents of thecontainer 20. - The configuration of a
particular container 20 will depend on the intended contents of thatcontainer 20. For example, some embodiments of thecontainer 20 can be configured for the purposes of storing beverages, food products, medicinal products, or other items intended to be ingested by a human being or other living being. Acontainer 20 for ingested items will have different operating requirements than acontainer 20 for non-ingested items. Somecontainers 20 may need to store hot liquids such as coffee while other embodiments may need to store cold solids such as ice cream as well as cold liquids such as melted ice cream. In some instances, the contents of acontainer 20 must be kept dry while in other embodiments the contents of thecontainer 20 are damp or even inherently wet. - Different embodiments of the
container 20 can have widely different shapes. A variety of different factors can individually or in combination with other factors impact the shape of thecontainer 20. Examples of potential factors can include but are not limited to the contents of thecontainer 20, ease of use, material composition of thecontainer 20, operating requirements of thecontainer 20, cost concerns, user expectations, durability requirements, transportation issues (including the ability to be effectively stacked), durability, and manufacturing constraints. - For example, in the context of a cup, the
container 20 is likely to be cylindrical in shape or at least substantially cylindrical in shape as is illustrated inFIGS. 1 a and 1 b. This is due primarily to user expectations and ease of use. In other contents, a rectangular box shape as illustrated inFIG. 1 c is the most desirable shape. As illustrated inFIGS. 1 a and 1 b, many embodiments ofcup containers 20 will be substantially cylindrical in shape rather than cylindrical in shape because the bottom portion of thecontainer 20 will be slightly smaller than the upper portions of thecontainer 20. This is to facilitate the ability to stacksuch containers 20 while they are in open and unfilled states. - As discussed below, the shape of the
container 20 can also be impacted by the operating state of thecontainer 20. For example, many embodiments of thecontainer 20 will have a circular or substantially circular horizontal cross-sectional shape when thecontainer 20 is an a fully open position, i.e. when thelid 28 is fully upright as illustrated inFIGS. 1 a, 1 b, and 1 c. The shape of such acontainer 20 when in a closed or partially closed state can become less circular and more elliptical in shape. The change in shape results from the motion of thelid 28, theplate 24, and portions of thebody 22 in the opening and closing of thecontainer 20. The doubled hinged architecture (seeelements 26 and 56) of acontainer 20 is complicated by the curved shape of thecontainer 20. Most examples of hinges in the prior art involve straight hinges. - In many embodiments, the shape of the
container 20 and the shape of theinternal cavity 46 of thecontainer 20 will mirror each other. For example, in the context of a coffee cup, theinternal cavity 46 will often be substantially cylindrical in shape. In some embodiments, the geometry of one ormore cavities 46 within thecontainer 20 can have a substantially different geometric shape than thecontainer 20. - The
container 20 can be implemented in ways that are consistent with ongoing non-disposable use, but many embodiments of thecontainer 20 will be configured for disposable embodiments. The desired lifespan of acontainer 20 can also be influenced by the intended lifespan of the contents of thecontainer 20 and the typical context of when acontainer 20 is loaded with its contents. For example, the cup inFIG. 1 a is intended for use in an environment where the cup is filled by the user of the cup (or a service provider serving the user). This is the typical context for soft drinks, coffee, tea, and other drinks. By contrast, the cup inFIG. 1 b is anaseptic container 20 that is filled and sealed prior to being distributed for consumption by users. - The innovative aspects of the
container 20 may be most beneficial in the context ofdisposable containers 20 becausedisposable containers 20 raise the most significant environmental concerns due to the sheer number ofsuch containers 20. For example, the number of disposable cups used and discarded each day is truly staggering. The high volume ofsuch containers 20 coupled with the disposable nature of disposable containers also serves to make them extremely cost sensitive components in an efficient supply chain. - Different embodiments of the
container 20 can be comprised of a wide variety of different materials. Thecontainer 20 was originally designed for use in the context of paper or paperboard disposable cups. However, different materials can be used For example, in the context of acontainer 20 serving as a cup the cup could be comprised of paper, paperboard, stainless steel, metal, ceramics, plastics, or other types of materials. Different types of coatings such as polymer coatings, high barrier polymer coatings (including but not limited to high carrier silver coatings), polyethylene coatings (including but not limited to polyethylene terephthalate coatings), biopolymer coatings (including but not limited to polylactide polymers), biodegradable polyester, and other types of coatings can be used with respect to thecontainer 20. Any of the materials discussed above with respect toaseptic containers 20 can also be used to reinforce the structure of acontainer 20 that is not aseptically sealed. - In many disposable embodiments of the
container 20, thecontainer 20 will be primarily comprised of paperboard or some similar material, but particular portions of thecontainer 20 may be reinforced with one or more coatings. - Different material compositions for
containers 20 can influence the different ways in which the different aspects of thecontainers 20 are shaped. For example, embossing (raising the material), debossing (recessing the material), stamping, folding, and cutting can be used to machine acontainer 20 comprised of paper, paperboard, or other materials. Such structural attributes can be critical to the functionality of thecontainer 20, but such attributes can also be very much constrained by the manufacturing constraints involved in implementing certain design features. - Many disposable containers in the prior art involve plastic lids. Such lids are not typically biodegradable and they require significant quantities of oil for their production. Such lids are used once, often for mere hours or even minutes, and then spend decades in landfills or as floating debris in the ocean. The
container 20 can be implemented in such a way as to be just as reliable as prior art containers, while being less expensive and less environmentally damaging at the same time. - The material composition and attributes of the
container 20 can also be impacted by requirements relating to thermal insulation -
Different containers 20 may involve vastly different operating parameters relating to temperature. Coffee and soup are served hot, while ice cream and frozen yogurt are served cold. The temperature of the contents within thecontainer 20 can impact the lifespan of thecontainer 20 as well as the ability of thecontainer 20 to satisfy the needs its users. - Some embodiments of the
container 20 will includedimples 31 or evendimple groups 33 to insulate the user of thecontainer 20 from the temperature of the contents of thecontainer 20.Dimples 31 can extrude outwards toward the external environment of the container, inward towards thecavity 46 of the container, or in both directions. -
Dimples 31 anddimple groups 33 serve can serve as a built in “sleeve” for coffee drinkers who would otherwise require an additional separate sleeve in order to enjoy their beverage. Sleeves could also me manufactured to includesuch dimples 31 anddimple groups 33. - The heat-flow attributes of a
container 20 can also be impacted through the use of multiple-wall 42 configurations, the ventilation of thecontainer 20, and the material composition of thecontainer 20. - Different containers can have different air flow requirements. The
same container 20 may have different requirements in different contexts. For example, while anaseptic container 20 containing juice or milk is closed and sealed, it should be essentially air tight for sanitation reasons. However, in the drinking a beverage from acontainer 20, there are ventilation and pressurization requirements to allow the beverage to flow out of thecontainer 20 consistent with user expectations. - In the context of
non-aseptic containers 20, desirable horizontal venting can be achieved throughventilation gaps 29. Some embodiments will use acover 27 shaped in such a manner to allow a beverage product to be ventilated immediately prior to being imbibed by the user, preventing the user from being injured by a drink that is too hot to safely consume. - A
rim 34 with a serrated edge can also enhance the ventilation of thecontainer 20 and its contents. - The attributes of flexibility and structural rigidity are important in the context of a
paperboard container 20 in which alid 28 is integral to thebody 22 of thecontainer 20. In moving thelid 28 between an open and closed operating state, certain portions of thecontainer 20 will need to be flexible to permit repeated movement between the various operating states. Simultaneously, other aspects of thecontainer 20 will need to be sufficiently rigid to sustain the structural integrity of thecontainer 20 while certain portions of thecontainer 20 are being flexible. - The attributes of flexibility and rigidity are discussed in greater detail below with regards to operation states of the
container 20. - As illustrated in
FIG. 1 d, many elements of thecontainer 20 can be described in terms of being asurface 75 or being ascore line 70. The core surfaces 75 of thecontainer 20 can include abody 22, alid 28, and aplate 24 that serves as an interface between thebody 22 and thelid 28. Many of the boundaries between thesedifferent surfaces 75 are marked byscore lines 75. - In many embodiments of the
container 20, all or substantially all of the components of thecontainer 20 are integral with thecontainer 20 and are not designed to be removable from thecontainer 20. What distinguishes the boundaries of different components or surfaces 75 in such embodiments can include: geometric shapes and dimensions; relative positions within thecontainer 20; function; relative movement capabilities; and embosses, debosses, score lines, and other types of folds, grooves, cuts, serrations, etc, (collectively “score lines”). -
Score lines 70 can be divided into two categories. Afoldable score line 71 is a score line that bends or folds to facilitate the movement of thelid 28. In contrast, a non-foldable score lines 72 is a score line that reinforces the structural integrity of a particular surface. As illustrated inFIG. 1 d, aplate hinge 26 acts as a hinge between thelid 28 and theplate 24 and abody hinge 56 acts as a hinge between theplate 24 and thebody 22. Thecontainer 20 utilizes a double-hinged architecture with twofoldable score lines 71 serving as two hinges that surround theplate 24.FIG. 1 e adds twoside flaps 54 to that configuration, with aside score line 55 connecting eachflap 54 to theplate 24 and a flapbottom score line 57 connecting eachflap 54 to thebody 22 of thecontainer 22. Thebody hinge 56,plate hinge 26,side score line 55, and flapbottom score line 57 are each examples offoldable score lines 71 because they are intended to be bent or folded to facilitate the opening and closing of thelid 28. Examples ofnon-foldable score lines 72 are discussed below, such as a vertical crease 25, asupport score line 38, a tabbase score line 48, acover score line 60, and astiffener score line 63, - The
container 20 can be implemented in a wide variety of different component configurations. Thecontainer 20 includes abody 22, alid 28, and abody hinge 56. All other components of thecontainer 20 are optional, depending on the particular embodiment. - In many embodiments of the container, the
body 22 and thelid 22 are intended to be permanently integral with each other. In other embodiments, theuser 20 may have the option of either temporarily or permanently removing thelid 22. - Many embodiments of the container 20 (see
FIGS. 1 a and 1 c) will also include aplate 24 that serves as an interface between thelid 28 and thebody 22. Many of embodiments of the container 20 (seeFIGS. 1 a and 1 b) will includeflaps 54 located near the base of thelid 28 that assist the user to seal thelid 28 in a closed position. Embodiments of thecontainer 20 that are configured to be filled and sealed prior to being provided to users (such asaseptic containers 20 containing products such as juices) can include aflange 59 that is used to seal the container. - Although not illustrated in any of the Figures, a
container 20 not designed to be filled by users can include both aplate 24 and aflange 59. -
Containers 20 serve to selectively contain and selectively make accessible the contents of thecontainer 20.Different containers 20 will have different operating states, different openings being capable of open or closed, and different components that will involved in transitioning from one operating state to another. - The
container 20 has alid 28 for opening and closing thecontainer 20. Thus, eachcontainer 20 will have at least two or more operating states. Theplate 24, flaps 54, tab(s) 30, passageway(s) 32, and potentially other components can individually possess operating states that transition from open to closed or closed to open as thecontainer 20 as a whole transitions from an operating state of a fully opened state to a fully closed state, and vice versa. -
FIG. 2 a is a diagram illustrating an example of an elevated rear view of acontainer 20 in a fully closed state. Thelid 28 is secured within aninner groove 52 in thebody 22, theopening 32 is blocked by thetab 30, and theplate 24 and flaps 54 are in fully closed positions. -
FIG. 2 b is a diagram illustrating an example of an elevated rear perspective view of acontainer 20 in a fully closed state except for anopen tab passageway 32. As discussed below, the passageway 32 (which can also be referred to as an opening 32) allows a user to access the contents of thecontainer 22 while thelid 28 is still in a sealed position. In the context of a cup, thepassageway 32 can be used to insert a straw, or the user can cause the contents to pour out thepassageway 32. In many embodiments, a horizontal cross section of thebody 22 inFIG. 2 b is substantially more elliptical in shape than the illustrating inFIG. 2 c. -
FIG. 2 c is a diagram illustrating an example of an elevated rear view of acontainer 20 in a partially open and partially closed state. Thelid 28 is no longer secured within theinner groove 52, and theflaps 54 andplate 24 are neither substantially parallel with abottom surface 40 of thecontainer 20 nor substantially straight up as when in a fully opened operating state. In many embodiments, a horizontal cross section of thebody 22 inFIG. 2 c is substantially more elliptical in shape than the illustrating inFIG. 2 d. -
FIG. 2 d is a diagram illustrating an example of an elevated rear view of acontainer 20 in a fully open state, such as the containers inFIGS. 1 a, 1 b, and 1 c. In many embodiments, a horizontal cross section of thebody 22 inFIG. 2 d is substantially circular in shape or at least substantially more circular in shape in comparison to the container inFIG. 2 b or evenFIG. 2 c. - Operating states are discussed in greater detail below. Different examples of operating states are illustrated in the changes from
FIGS. 2 a-2 d.FIGS. 8 a-8 c discloses similar states from a different view.FIGS. 8 a-8 c are discussed below. - Different embodiments of the
container 20 can involve a variety of different methods for opening and closing thecontainer 20. Moreover, as identified above and illustrated inFIGS. 2 a through 2 d, thecontainer 20 can possess more than two operating states. Different components within thecontainer 20 are capable of having opened, closed, or partially opened/partially closed individual operating states. - There are a variety of different ways to open and close the
container 20. Different users may behave differently. For example, some users may tend to press down on thelid 28 to close thecontainer 20 while other users may tend to press down on theplate 24. Similar variations may be practiced in terms of opening thecontainer 20. - 1. Opening the Container
-
FIG. 3 a is a flow chart diagram illustrating an example of a method for opening acontainer 20. At 200, theedge 51 of thelid 28 is dislodged from theinner groove 52 of thebody 22. The process at 200 is analogous to the differences betweenFIG. 2 b andFIG. 2 c discussed above. At 200, the process unseals thecontainer 20 and permits the various components to move as they are configured to move. - At 202, the
plate 24 and flaps 54 flex. The process at 202 is illustrated by the differences betweenFIGS. 2 b and 2 d. - At 204, the
lid 28 is lifted into a straight up position as illustrated inFIGS. 1 a, 1 b, 1 c, and 2 d. - The loading or filling to the
container 20 could occur while in potentially any of the states identified above. - The closing/sealing process ends after the closing of the
opening 32. - 2. Closing the Container
-
FIG. 3 b is a flow chart diagram illustrating an example of a method for closing acontainer 20. The process ofFIG. 3 b can be characterized as the process ofFIG. 3 a, except in reverse. - At 206, the
plate 24 and flaps 54 are flexed while thelid 28 remains substantially upright. - At 208, the
lid 28 is pressed downward. - At 210, the
edge 51 of thelid 28 is secured within theinner groove 52 of thebody 22. - Different users may close the
container 20 applying pressure in different ways. For example, users could press down on thelid 28 or theplate 24 to initiate the closing process. - Different embodiments of the
container 20 can utilize different manufacturing processes and different combinations of tooling. In some instances, a single design of acontainer 20 can be manufactured in a variety of different ways. With respect to embodiments of thecontainer 20 comprised exclusively or primarily with some type of paper or paperboard, the process of manufacturing thecontainer 20 involves creating blanks, flat two dimensional cutouts that are subsequently shaped and treated to ultimately form thecontainer 20. Certain score lines, coatings, and other processing may be performed on a blank, while other processing can be performed after one or more blanks have been combined and shaped. - 1. Two Blank Configuration
-
FIG. 4 a is a flow chart diagram illustrating an example of a method for manufacturing acontainer 20 from two blanks.FIG. 5 a is a diagram illustrating an example a top blank 100 andFIG. 5 b is a diagram illustrating an example of bottom blank 102. - Returning to
FIG. 4 a, at 212, a bottom blank 100 and a top blank 102 are created. - At 214, the bottom blank 100 is fused together with the top blank 102 as the
container 20 is shaped into a cup. - The manufacturing process is described in greater detail below. In many embodiments, all score lines except for the
inner groove 52 and body hinge 56 are implemented prior to the securing of the top blank 102 to the bottom blank 100. In other embodiments, all score lines can be added as part of the blank preparation process that occurs prior to combining the blanks. - There are advantages to machining the
body hinge 56 andinner groove 52 after the blanks have been fused together and shaped. By doing so on the shaped and fused shell, thebody hinge 56 can be implemented in the shape of a substantially curved arc rather than a straight line segment. A contrast ofFIG. 7 a withFIG. 7 b illustrates this difference. - In
FIG. 7 a, thecurved body hinge 56 coupled with theinner groove 52 together form asingle score line 61 that encircles all or substantially all of a horizontal cross section of thebody 22. InFIG. 7 b, thebody hinge 56 is straight, impacting the overall shape of thescore line 61. - It is counterintuitive that use of a circular tool to create a circular score line (the
combination loop 61 formed by thebody hinge 56 and inner groove 52) is desirable, but such a process can be desirable and it can lead to superior results. - As discussed in greater detail below, a substantially
circular combination loop 61 as illustrated inFIG. 7 a (in contrast to the ends of a substantially circularinner groove 52 mating with the ends of a substantially straight body hinge 56 as illustrated inFIG. 7 b) make thecontainer 20 more circular in shape when thecontainer 20 is in a fully opened state. This has useful features in terms of stackability and durability. However, the fact that such an implementation involves a circular or substantiallycircular body hinge 56 is a result that is not taught in the prior art, and is counterintuitive to those of ordinary or even superior skill in the applicable art. - By having the
inner groove 52 and body hinge 56 machined as a singular circular loop, the flexural strength and crush resistance of thecontainer 20 is enhanced as a result of the top to bottom compression strength. Various processing can be used to enhance thecombination loop 61 and further strengthen the overall structure of thecontainer 20. - 2. Three Blank Configuration
- Although the
container 20 can be manufactured using a two blank configuration as described above, there are advantages to using a three blank configuration in which theloop 61 is machined into thecontainer 20 after alid blank 104 and a sidewall blank 106 are fused together, and then shaped around thebottom blank 100. - As described above, the three blank configuration of
FIG. 4 b can also involve machining theprimary score line 61 comprising thebody hinge 56 and theprimary groove 52 after thecontainer 20 has been shaped into a substantially cylindrical shape. In other embodiments, all score lines can be machined into the blanks prior to the process of fusing them together. -
FIG. 5 c is a diagram illustrating an example of a lid blank 104 used in the process illustrated byFIG. 4 b.FIG. 5 d is a diagram illustrating an example of a sidewall blank 106 used in the process illustrated byFIG. 4 b. Different embodiments of thecontainer 20 can involve different component configurations with many of those differences manifesting themselves in the blanks used to make thecontainers 20. For example,FIG. 5 c discloses vertical creases 25 to reinforce thelid 28 of thecontainer 20. A reinforcement member 23 is used to connect the lid blank 104 with theplate 24 of the sidewall blank 106, strengthening thecontainer 20 as thecontainer 20 is transitioned between open, semi-open/semi-closed, and closed operating states.FIG. 5 c also illustrates acover 27 that is different than atab 30. Other features that may be highly desirable are the curved side flaps 55 and aflap angle 97 of between about 35 degrees and about 70 degrees. - There are several advantages to the 3 blank manufacturing process of
FIG. 4 b over the 2 blank manufacturing process ofFIG. 4 a. The process disclosed inFIG. 4 b can prevent lid staining and wicking. Thelid 28 can be better protected against humidity. Costs and waste is reduced by reducing the amount of scrap paper board that results because a three blank configuration requires fewer sheets of paperboard than a two blank configuration. -
FIG. 4 b is a flow chart diagram illustrating an example of a method for manufacturing acontainer 20 utilizing 3 blanks. - At 216 a
sidewall blank 106 and a lid blank 104 are prepared. - At 218, the
sidewall blank 106 and the lid blank 104 are fused together into a fused blank. - At 220, a bottom blank 100 is prepared.
- At 222, the fused blank is shaped into a shell around the
bottom blank 100. - At 224, the bottom blank 100 is secured within the bottom portion of the shaped shell.
- The process of machining the
score line 61 that comprises thebody hinge 56 and theinner groove 52 can be implemented at potentially any time after thelid blank 104 and the sidewall blank 106 are combined and shaped into the shape of thecontainer 20. The shaping of the fused blank typically happens in conjunction with insertion of the bottom blank 100. - The manufacturing process is described in greater detail below, The
container 20 ofFIG. 2A can be manufactured on a mass production and cost effective basis using substantially unmodified prior art machine tools. Utilizing the infrastructure provided below the table of such tools, the desired modifications can be made to functionality provided above the table. The ability to utilize prior art tools is a significant advantage in terms of market penetration and the costs associated with the production ofcontainers 20. - Although
containers 20 are used primarily with respect to the contents-related (i.e. product-related) functionality,containers 20 can be implemented in ways to serve additional functions. -
Containers 20 can provide an excellent opportunity for businesses and other organizations to facilitate communications. In many instances, thecontainer 20 can include text, graphics, and other indicia to communicate brand identity, product information, marketing information, or public service announcements. As miniature electronic components become increasingly easy and inexpensive to incorporate into containers, somecontainers 20 can be configured to provide audio communications using technology similar to that used to play music when someone opens a greeting card. Acontainer 20 can also be configured to use powered electronics to flash lights or otherwise generate visual indicia. For example, acoffee cup 20 container could be configured to play a song, flash a light, and/or generate some other response upon the opening or closing of the lid.Containers 20 can also utilize connectivity and communication technologies such as RFID technology to track the movement and usage of thecontainer 20. - Such configurations may involve specific compartments within the
container 20 for hosting the ancillary/supplemental component. In some embodiments, a multiple body wall structure could include a cap within the wall to contain the particular component. In other embodiment, a specific compartment is shaped in the applicable location within thecontainer 20 for use of the ancillary/supplemental component. - The prior art appears to affirmatively teach away from the innovative attributes of the
container 20. Many applications of container technology exhibit relatively few changes in recent years. For example, the common disposable cups of 2011 are not all that different from the disposable cups that were manufactured in 2001, 1991, 1981, or even earlier. There are significant reasons for the lack of innovation in many areas of container design such as disposable cups. Disposable cups are extremely high volume commodities that are subject to significant cost constraints and relatively high functional reliability requirements. When cost constraints and reliability requirements are coupled with intrinsic manufacturing limitations, it is easy to see why the conventional disposable cup has not changed much over the years. For example, to the extent that some individuals may have sought to design a paper cup with an attached lid not comprised of plastic, such designs were at best too expensive to manufacture or insufficiently reliable for consumer use. At worst, such approaches could actually be impossible to mass produce effectively. - The unfortunate interactions of economic, reliability, and manufacturing constraints have in many respects hampered innovation in disposable container technology. For example, the
curved hinge 56 illustrated inFIGS. 2 d, 6 b, 6 c, 7 a, 7 d, and 9 b is believed to be actively taught away from by the prior art. Similarly, attributes such as the horizontal venting throughventilation gaps 29, a debossedcover 27, curved side score lines 55, the use of aplate 24, the use of aplate 24 in conjunction withflaps 54 and/or a reinforcement member 23 appear to run counter to the teachings of the prior art. - The prior art approach to many structural and insulation issues is to add thickness to the
container 20, an approach which is directly contrary to the flexibility required to mass produce acontainer 20 with anintegral lid 28 made of a paperboard or similar material. - The prior art teaches away from the
container 20 in part because of cost constraints, functionality requirements, manufacturing constraints, etc. have collectively left those of ordinary skill in the prior art into an intellectual dead end with respect to the design of containers, particularly in the context of disposable containers. - In accordance with the provisions of the patent statutes, the principles and modes of operation of the container have been explained and illustrated in a variety of embodiments and configurations. However, it must be understood that this
inventive container 20 may be practiced otherwise than is specifically explained and illustrated without departing from its spirit or scope. - Similarly the methods of using containers and the methods of manufacturing containers should also be interpreted broadly.
-
FIG. 2 a is a diagram illustrating an example of an elevated rear view of acontainer 20 in a fully closed state. - The
container 20 illustrated inFIG. 2 a is a cup that can be machined from and/or into a single piece of paper, paperboard, or similar material. Different ways to manufacture thecontainer 20 are described in detail below. - Different embodiments of the
container 20 can involve different types of products, different material compositions, and different manufacturing processes. Each embodiment of thecontainer 20 will include a container body (the “body”) 22 and alid 28. Somecontainers 20 can include more than onebody 22 and/or more than onelid 28. Thebody 22 andlid 28 can be implemented in a wide variety of different shapes and sizes using different materials and coatings. Thecontainer 20 will also include abody hinge 56. All other components in the various Figures are optional and need not be included in all embodiments of thecontainer 20. - Most embodiments of the
container 20 will include aplate 24 that is connected to both thelid 28 and to thebody 22, with one end of theplate 24 being connected to thelid 28 and the other end of the plate being connected to thebody 22. Embodiments that include aplate 24 will typically include aplate hinge 26 and flaps 54, although the presence offlaps 54 does not necessitate the presence of theplate 24. - In some embodiments, the
lid 28 and even theplate 24 can be configured to be removable from thecontainer 20, such as through perforated edges to a paperboard or other material that can be removed by hand. In other embodiments, thebody 22,lid 28, andplate 24 are integral to each other and are not configured to be intentionally separable from each other. - The
body 22 of thecontainer 20 typically constitutes the majority of the surface area of thecontainer 22. Thebody 22 of thecontainer 20 also typically defines the shape, size, and contours of thecontainer 20. For example, inFIG. 2 d, thecontainer 20 is a cup that is substantially cylindrical in shape. The shape of thecontainer 20 inFIG. 2 d is the result of a substantiallycylindrical body 22. Thebody 22 of thecontainer 20 may include various score lines for the purposes of reinforcing the structural strength and integrity of thecontainer 20 as well as functions such as sealing thelid 28 in a closed position. As discussed both above and below, the shape of thecontainer 20 can be significantly less cylindrical when thecontainer 20 is a fully closed position. Various figures can be contrasted to visualize this attributes. For example, the containers 20 a stack ofcontainers 20 illustrated inFIG. 9 b are in a fully open state and thus substantially cylindrical in shape (which facilitates better stacking capabilities) while the overall shape of thecontainers 20 stacked inFIG. 9 a are substantially more elliptical in shape. The difference being that thecurved hinge 56 in the open position ofFIGS. 9 b and 9 c is substantially straight when thecontainer 20 is the closed position ofFIG. 9 a. - In contrast to other components of the
container 20, thebody 22 is designed to be the least impacted by the transition of thecontainer 20 from one state to another. Many portions of thebody 22 such as the bottom surface orbase 40 of thebody 22 are totally unaffected by transitions in operating states. However, the portion of the body immediately underneath thebody hinge 56 can be significantly impacted by the transition of the container from a fully opened to a fully closed state, or vice versa.FIG. 7 f (thebody 22 when thecontainer 22 is in a fully open state) andFIG. 7 g (thebody 22 when thecontainer 22 is in a fully closed state) are discussed below. - The bottom portion of the
body 22 typically serves as thebase 40 of thecontainer 20 with thelid 28 being placed in a vertical position that is higher than most or even all of thebody 22, depending on the particular embodiment of thecontainer 22 and the particular operating state of thelid 28. InFIG. 2 a, the uppermost portion of a tab 30 (which can extend off of and be part of the lid 28) represents the highest vertical point on thecontainer 20 in a conventional orientation of thecontainer 20 when thecontainer 20 is in a fully closed operating configuration/state. Conversely, the lowest vertical portion of thecontainer 20 illustrated inFIG. 2 a is abase surface 40 of thebody 22 upon which thecontainer 20 sits when placed on a substantially flat surface such as a table. The relative vertical directions of up and down, as well as the perspective of relative horizontal attributes versus relative vertical attributes are discussed from the perspective of acontainer 20 supported by thebase 40 on a substantially flat surface. - In many embodiments of the
container 20, thebody 22 will be comprised primarily of paper or paperboard. Different embodiments of thecontainer 20 may require additional linings, additional material, or entirely different material. For example, polyethylene can be used to reinforce certain portions of thebody 22 or can be used to comprise theentire body 22. Moreover, in an aseptic embodiment of thecontainer 20, the list of materials for use in thebody 22 can include but are not limited to paperboard, aluminum foil, metalized film, ethylene acrylic acid, low-density polyethylene, liner low-density polyethylene, nylon, polypropylene, polystyrene, polyvinylidine chloride, and/or ethylene vinyl alcohol. - The
body 22 of thecontainer 20 can itself be broken down further into various components and elements. Some elements such as acavity 46 are inherent to the concept of acontainer 20 while other elements such as a curledrim 34, ahead wall 36 above theinner groove 52, and the platesupport score lines 38 are optional. - 1. Cavity
- A cavity 46 (which can also be referred to as a chamber 46) is the empty space within the
body 22 of thecontainer 20 that is used to store the contents or product. For example, in the context of acoffee cup container 20, thecavity 46 is the space within thebody 22 that houses the coffee. - The
cavity 46 is illustrated inFIG. 6 a. Dotted lines are used to illustrate the contours of thecavity 46 because thewall 42 of thebody 22 blocks thecavity 46 from view. Thecavity 46 includes a bottom boundary which can be referred to as an internal floor surface 39 (which can also be referred to a cavity bottom 39) and interior walls 44. - In many embodiments of the
container 20, thecavity 46 will be shaped in a substantially identical manner to the outer appearance of thebody 22. However, in alternative embodiments, different shapes and configurations can be implemented, particularly if thecontainer 20 requires structural reinforcements to maintain the integrity of thebody 22. In such instances, reinforcing structures may be placed within thebody 22, altering its interior shape, i.e. the shape of thecavity 46. Different shapes may also be utilized if some of the ancillary/supplemental components discussed above are implemented for a particular embodiment of thecontainer 20. - Some embodiments of the
container 20 can includemultiple cavities 46 for separating two or more products within thecontainer 20. Such embodiments can include internal structures to mix the contents if desired, or to keep them permanently separate. For example acontainer 20 could be configured to hold 2 different and separate drinks, with thecavity 46 being split into two separate holding areas.Other containers 20 involving foodstuffs or contents having nothing to do with beverages or food can also involve partitionedcavities 46. - 2. Walls
- The
cavity 46 of thebody 22 is shaped by the material surrounding thecavity 46 which can be referred to as awall 42. In the context of a cylindrically shaped or substantially cylindrically shapedcavity 46, thewall 42 will often be similarly shaped. Some embodiments of thecontainer 20 can involve single-layered wall architecture. Other embodiments may involve a framework involving two, three or more layers. For example, in some embodiments, a three layered approach involving two layers of material surrounding a layer of air can be used to comprise thewalls 42. Some attributes of the wall(s) 42 will be dependent upon manufacturing concerns. For example, in shaping a substantiallycylindrical container 20 from a substantially flat blank or combination of blanks, an adhesive can be used to secure the shape of the cup. Temperature, pressure, folding, embossing, debossing, and other processes can also be used in shaping and securing the wall(s) 42. Such processes will impact the attributes of the wall(s) 42. - In the context of
containers 20 used for beverage or food products, thecontainer 20 can be manufactured such that no adhesive is used on a portion of an interior surface 44 of awall 42. This prevents such an adhesive from coming into contact with the contents of thecontainer 20, which can be desirable in terms of complying with Food and Drug Administration (“FDA”) regulations. - In aseptic embodiments of the
container 20, thewalls 42 will not be comprised primarily of paperboard. If paperboard is used, it will be used in conjunction with substantial portions of other materials. - 3. Rim
- As illustrated in
FIG. 2 a, a rim 34 (which can also be referred to as a top curl 34) can represent the highest vertical position of thebody 22. Therim 34 is typically a reinforced exterior surface at the top of thebody 22. Some embodiments of thecontainer 20 will not include arim 34, but therim 34 is often useful for strengthening and reinforcing the structural integrity of thecontainer 20.Rims 34 can also aid users in the use of thecontainer 20. For example, in the context of acup container 20 used to hold a beverage, therim 34 can assist a drinker in avoiding a spill as well as making the coffee cup container more comfortable to use. Therim 34 can also insulate the drinker from a beverage that is particular hot or particular cold. For example, arim 34 with a serrated edge may serve to cool a hot beverage as the user drinks from thecontainer 20. Therim 34 can also include a pinched end secured with a pinch lock. - As illustrated in
FIG. 2 a, therim 34 can comprised in the shape of a tube or a close geometric proximity to a full curl. In many embodiments of thecontainer 20, therim 34 is substantially in the shape of a hollow cylinder. In some embodiments, therim 34 may have the shape of a partial cylinder with less than 360 degrees of surface - In the illustration of
FIG. 2 a, therim 34 is on top of aportion 36 of thebody 22 that is vertically higher than thelid 28 when thelid 28 is in a fully closed configuration/state (i.e. when thelid 28 is secured within an internal groove 52). Thetop portion 36 of thebody 22 often includes a variety of score lines, which can be vertical, horizontal, or a combination thereof. Theportion 36 of thebody 22 that is vertically above theinternal groove 52 can also be referred to as the head-wall 36 of thebody 22. Therim 34 resides on top of the head-wall 36. - In some embodiments of the
container 20, therim 34 will cover the entire portion of thebody 22 that is not covered by theplate 24 or aflap 54. In other embodiments of thecontainer 20, coverage of therim 34 is not comprehensive, allowing in certain embodiments, theportion 36 of thebody 22 closest to theflaps 54 to be folded inwardly to reinforce the functionality provided by theflaps 54. To maximize the flexibility of theplate 24 and or flaps 54, it is often desirable for at least a couple of millimeters of thetop portion 36 to not be covered by therim 34. - In many embodiments of the
container 20 that involve a cylindrical or substantiallycylindrical body 22, therim 34 forms anarc 41 between approximately 299 degrees and approximately 180 degrees. In alternative embodiments, thearc 41 could reach approximately 270 degrees or form significantly less than a 180 degree semi-circle. InFIG. 6 b, thearc 41 is approximately 270 degrees. InFIG. 6 c, the arc 4 l is approximately 180 degrees. Any variation between those two values can be implemented in various embodiments of thecontainer 20. In many embodiments, it is desirable for thearc 41 to be between about 200 degrees and 240 degrees. - 4. Head-Wall
- The head-wall 36 (which can also be referred to as a headwall 36 or head wall 36) underneath the
rim 34 can provide Insulation and a barrier for safety, making thecontainer 20 easier to use, particularly with respect to embodiments involving liquid beverages. The head-wall 36 is the portion of thebody 22 that is below therim 34 but above theloop 61 formed by thebody hinge 56 andinner groove 52. - 5. Interior Surfaces Vs. Exterior Surfaces
- In many embodiments of the
container 20, there is a surface or other element that faces inwards towards thecavity 46 and a corresponding surface or other element that faces outwards towards the environment of thecontainer 20. - The
walls 42 of thebody 22 are made up of both exterior surfaces and interior surfaces. An exterior surface is a surface of thewall 42/body 22 that faces outward from thecontainer 20. An interior surface 44 is a surface of thewall 42/body 22 that faces inward towards thebody 22, typically thecavity 46 or in some embodiments, another interior surface that compartmentalizes thecavity 46.FIG. 6 a illustrates internal surfaces. The other figures focus on external surfaces. - Similarly, the headwall 36 has an inward facing surface and outward facing surface. The score line represented by
element 53 is the exterior face of theinner groove 52, both of which are part of theloop 61 that encircles thecontainer 20. - In
FIG. 2 a, oneexterior surface 42 of thebody 22 is the portion of thebody 22 that is substantially cylindrical in shape that runs from a bottom to the top of thebody 22. A corresponding interior surface 44 that is illustrated with a dotted line because it is not visible from the exterior of thecontainer 20 is also cylindrical in shape and runs from a bottom to the top of thecontainer 20. - The head-
wall 36 of thebody 22 that extends upwards from theclosed lid 28 includes both an exterior surface as well as an interior surface. Therim 34 rests on thevertical protrusion 36. - The bottom portion of the
body 22 includes both interior surfaces 39 (facing upwards towards the cavity 46) and exterior surfaces 40 (facing downwards towards the surface on which thecontainer 20 rests). The bottommost exterior surface of thebody 22 is referred to as abase 40. The bottommost interior surface of the body 22 (which can also be thought of as the bottommost exterior “surface” of the cavity 46) is referred to as afloor 39. Thefloor 39 of the cavity is illustrated with a dotted line inFIG. 6 a because thecavity 46 is not visible from the outside of thecontainer 20. A wide variety of different designs can be incorporated into thebase 40 of thecontainer 20. The shape of thecontainer 20 will typically impact the desirable shape and configuration of thebase 40. - 6. Score Lines
- A score line is a fold or crease in the material of the
container 20. Score lines can be implemented through the application of pressure, heat, or combinations of both. As illustrated inFIG. 2 a, thebody 22 of thecontainer 20 can include a variety of different score lines to reinforce the strength of thebody 22 or for other purposes. Other parts of thecontainer 20 such as theplate 24, theflaps 54, or thelid 28 can also include score lines for structural reinforcement purposes as well as for the purpose of facilitating the movement of thelid 28 between open and closed operating states. - In the context of the
body 22, the purpose of a score line is typically to constrain movement or deformation. Score lines can be oriented vertically (see element 38) or horizontally (see element 56). Different embodiments of thecontainer 20 can include fewer score lines or more score lines than the illustration inFIG. 2 a. - Score lines can fully encircle a cross section of the
container 20 or be only partial in scope. For example, a substantially horizontal score line 61 (which can also be referred to as a “loop” 61) could run across the entire circumference of acylindrical body 22. In contrast, a partial horizontal score line may be limited to running under only through the portions of thebody 22 that are directly under theplate 24, theplate 24 and flaps 54, therim 34, or some other component or element. Ahorizontal score line 56 separating thebody 22 from theplate 24 and flaps 54 can also be referred to abody hinge 56. It is often helpful to include horizontal score lines on thebody 22 of thecontainer 20 that are parallel to the score line serving as body hinge 56 between theplate 24 and thebody 22 because theconnector 56 between theplate 24 and thebody 22 is often important in supporting the ability of theplate 24 to support the movement of thelid 28. - Vertical score lines can similarly be full (running from top to bottom) or merely partial. As illustrated in
FIG. 1 a, vertical score lines 38 (which can also be referred to as “plate support score lines” 38) in thebody 22 can extend upwards to theplate 38 to reinforce the structural integrity of theplate 24 and the ability of theplate 24 to assist in securing thelid 28 in a closed position. Some embodiments of thecontainer 20 may include full vertical score lines spaced evenly throughout portion of thebody 22 covered by therim 34. For example, vertical score lines could be placed below therim 34 every “X” number of millimeters to enhance the structural strength of thecontainer 20. Horizontal score lines could also be distributed throughout thebody 22 to reinforce the structure of the body. However, one particularhorizontal score line 61 is particularly important. As illustrated inFIGS. 7 a and 7 b, theprimary score line 61 can comprise thebody hinge 56 and theinner groove 52. The body hinge 56 can have a significant impact on the functionality of thecontainer 20 as well as the shape of thecontainer 20. - With the exception of the body hinge 56 (and the flap
bottom score lines 57 if present), the score lines 70 on thebody 22 of the container are non-foldable score lines 72. - a. Body Hinge
- The
horizontal score line 61 can include thebody hinge 56 or in other words, thebody hinge 56 can be part of a greaterhorizontal score line 61. The body hinge 56 can divide thebody 22 of thecontainer 20 from theplate 24 and flaps 54 of thecontainer 20. The body hinge 56 it is attached to thebody 22 of thecontainer 20 and it serves as a hinge to facilitate the opening and closing of thelid 28. The body hinge 56 is one of the components that is illustrated inFIGS. 1 a, 1 b, and 1 c. - The body hinge 56 works in conjunction with the
plate hinge 26 to facilitate the opening and closing of thelid 28. Thebody hinge 56 and the innergroove score line 52 can fully encircle a cross-section of thecontainer 20 or in other embodiments, substantially encircle a cross-section of thecontainer 20. - As discussed below, the inner
groove score line 52 is typically circular in shape or substantially circular in shape in the context of acontainer 20 that is substantially cylindrical in shape. As illustrated inFIG. 7 b, the shape of thebody hinge 56 can be in the shape of a substantially straight line segment connecting to a substantially curved innergroove score line 52. As is illustrated inFIG. 7 c, the shape of thebody hinge 56 can be that of a substantially curved/circular arc connecting a substantially curved/circular innergrove score line 52. In many embodiments of thecontainer 20, thebody hinge 56 is substantially curved in shape (with a substantially circular loop 61) when thecontainer 20 is in a fully open position and substantially straight in shape when thecontainer 20 is in a fully closed position. In other embodiments, even an open state of thecontainer 20 will involve abody hinge 56 that is substantially less circular. - The shape of the
body hinge 56 will often depend on the manufacturing process. If thebody hinge 56 is machined into the blank prior to the fusing of the blanks together, thebody hinge 56 will be substantially more straight than it otherwise would be. If in contrast, theprimary score line 61 is machined after the blanks have been fused together and shaped, thebody hinge 56 can be substantially circular when thecontainer 20 is in a fully open state. - In many embodiments, the
body hinge 56 is a score line. However, in alternative embodiments of thecontainer 20, different types of processing (i.e. not necessary score lines) can be implemented into thecontainer 20 to provide for the functionality of thebody hinge 56 or other types of hinges. - b. Inner Groove Score Line
- Some embodiments of the
container 20 can include horizontal score line 52 (the “inner groove score line” 52) that connects with thebody hinge 56 to form ascore line 61 that substantially circles or even fully encircles an outer surface cross section of thecontainer 20. SeeFIGS. 7 a and 7 b. - The interior facing surface of the
inner groove 52 can be used to help seal with lid in a closed position. This can be true in both aseptic and non-aseptic embodiments of thecontainer 20. However,aseptic containers 20 with the aid of theflange 59 have less need of theinner groove 52. The exterior facing surface of theinner groove 52 serves to sustain the structural integrity of thecontainer 20. - The cavity of the inner
grove score line 52 can be referred to as theinner groove 52 or the lidchannel seat groove 52.FIG. 8 c provides an example of theinner groove 52 serving to secure thelid 28 in a closed and sealed state.FIGS. 8 d and 8 e illustrate examples of aninner grove 52. In many embodiments of thecontainer 20, aninner groove angle 64 of about 30 degrees is highly desirable. In alternative embodiments, theinner groove angle 64 can range as low as about 20 degrees and as high as about 60 degrees. In many embodiments of thecontainer 20, theinner groove 52 will have a cross section that is substantially convex in shape. - In many embodiments, the
inner groove 52 is formed as a score line. However, in alternative embodiments of thecontainer 20, different types of processing (i.e. not necessarily score lines) can be implemented into thecontainer 20 to provide for the functionality of agroove 52 that serves as a mechanism for securing thelid 28. For example aflange 59 could be used instead of theinner groove 52 or in addition to aninner groove 52. - c. Chevrons
- A chevron can be embossed or debossed into any portion of the
container 20, including thebody 22, theplate 24, or thelid 28. Chevrons serve to structurally reinforce the applicable portion of thecontainer 20. No chevrons are illustrated in thebody 22 of thecontainer 20 inFIGS. 2 a-2 d.FIG. 6 g illustrateschevrons 59 on thelid 28.Similar chevrons 59 can be placed elsewhere on thecontainer 20 including thebody 22 or theplate 24 to facilitate the structural integrity of thecontainer 20. - d. Dimples/Dimple Groups
- In order to facilitate better thermal insulation, make the
container 20 easier to grip, or just to alter the way users experience thecontainer 20, thebody 20 of thecontainer 20 can include a variety ofdimples 31 or even dimple groups. -
FIG. 11 a is diagram illustrating an example of a sidewall blank 106 that includes twogroupings 33 ofdimples 31. Thedimple groups 33 are positioned on thewall 42 of the body to facilitate grip and heat insulation. The number, shape, size, and position ofdimples 31 can vary widely from embodiment to embodiment of thecontainer 20. Somecontainers 20 will not include anydimples 31. Some embodiments of thecontainer 20 may be used in conjunction with sleeves that havedimples 31 in lieu of thewall 42 itself having dimples 31. -
FIG. 11 b is a diagram illustrating an example of acontainer 20 with abody wall 42 substantially covered indimples 31. Although there is no inherent limit to the number and usage ofdimples 31 there is little reason in most instances to go beyond the boundary of thebody 22wall 42 in the placement ofdimples 31. - In many instances, dimples 31 will protrude to the exterior of the
container 20. However, dimples 31 can be implemented to protrude inwards to thecavity 46 or in both interior and exterior directions.FIG. 11 c is cross section diagram of abody wall 42 withdimples 31 protruding outward from thecontainer 20.FIG. 11 d is a cross section diagram of a body wall with dimples protruding inward towards the cavity of the container.FIG. 11 e is a cross section diagram of a body wall with dimples protruding both inwards towards the cavity of the container and outward towards the external environment of the container. -
Dimples 31 can be implemented in a variety of different shapes, sizes, and configurations. In addition to heat insulation functionality, dimples 31 can also enhance the user experience in handling thecontainer 20.Dimples 31 impact the look of thecontainer 20, as well as the resulting sense of touch that a user experiences while in contact with thedimples 31 on thecontainer 20. - 7. Bottom Portion
- The bottom 40 surface of the
body 22 serves as the bottom of thecontainer 20. There are a wide variety ofdifferent bottoms 40 that can be incorporated into thecontainer 20. In some instances, the contents ofcontainer 20 will impact the structure of the bottom 40. The bottom 40 can be curled (seeFIG. 10 f) as well as finished, knurled, and squared (seeFIG. 10 g). - A
plate 24 is a surface area of thecontainer 20 that is configured to support the movement of thelid 28. Theplate 24 acts as an interface between alid 28 that must move in order for thecontainer 20 to be opened or closed and abody 22 that involves far less movement. - Just as the
body 22 can have exterior surfaces facing in an outward direction and interior surfaces facing in an inward direction, theplate 24 can include both an outward surface and an inward surface. Similarly, theplate 24 can also include both vertical and horizontal score lines with the boundaries of theplate 24 being typically marked by score lines. Aplate 24 can include side score lines 55 andhorizontal score lines - The
plate 24 and twoflaps 54 that are illustrated inFIG. 2 a facilitate the ability of users to open and close thelid 28 while facilitating the strength and tightness of thecontainer 20. If thelid 28 cannot be secured in a closed position, then the ability to utilize thecontainer 20 is compromised because an unfastenedlid 28 can result in the unintended change of an operating configuration/state from closed to open. For example, in the context of abeverage container 20, acontainer 20 that cannot be closed and sealed in a watertight manner is of only limited use. - Embodiments of the
container 20 that include aplate 24 allow for thelid 28 to be open or closed without altering the structure of thelid 28. By leaving the structure oflid 28 unchanged, the structural integrity of thelid 28 and the ability of aclosed lid 28 to seal the contents of thecavity 46 are enhanced. The motion of thelid 28 is facilitated by theplate 24 or theplate 24 in conjunction with theflaps 54. A variety of score lines are typically used to delineate the boundaries of theplate 24 and flaps 54. - Just as the
body 22 can be comprised of a wide range of different materials or combinations of those materials, so can theplate 24 be similarly comprised. In some embodiments, differences in materials composition, thickness, and/or other factors relative to theplate 24 and thebody 22 can be used to enhance the functionality of theplate 24 in facilitating the movement of thelid 28 into open and closed positions. - As discussed above, different embodiments of the
container 20 can utilize different types of score lines at different locations with different attributes - 1. Body Hinge
- The body hinge 56 connects the
plate 24 to thebody 22. The body hinge 56 is discussed above. The body hinge 56 in many embodiments of thecontainer 20 represents the lowest part of thecontainer 20 that is designed to move with the opening or closing of thelid 28. As discussed above and below and as is illustrated by contrastingFIG. 7 f withFIG. 7 g orFIG. 7 c withFIG. 7 d, the movement of thebody hinge 56 involves moving the portion of thebody 22 beneath thebody hinge 56. - 2. Plate Hinge
- Returning to
FIG. 2 a, aplate hinge 26 connects theplate 24 to thelid 28. Theplate hinge 26 is a score line that traverses all or substantially all of the boundary between theplate 24 and thelid 28. It may also divide portions of the flaps 54 (if any) that may be in contact with thelid 28. - The
plate hinge 26 and thebody hinge 56 can function in conjunction with each other as a dual hinged closing/opening mechanism for thecontainer 20. Examples of plate hinges 26 are illustrated inFIGS. 1 a, 1 c, 2 a-2 d, and 6 d.FIG. 6 e illustrates an example of aplate hinge 26 that includes ahinge break 45. - 3. Side Score Lines
- Two side score lines 55 serve to connect the
plate 24 from twoexterior flaps 54 in embodiments of thecontainer 20 that include the twoflaps 54. As illustrated inFIGS. 5 c and 5 d, the side score lines 55 can be curved. Curved side score lines 55 can form a substantiallycircular arc 41 along with thelid 28. The curved shape of the side score lines 55 can enhance a largercircular arc 41 and preserve a more circular or elliptical shape of the container 20 (if thecontainer 20 is substantially circular or elliptical in shape in the first place) when thecontainer 20 is in a closed position. - 4. Flaps
- Many embodiments of the
container 20 will include twoflaps 54, one to each side of theplate 24, to facilitate the sealing of thecontainer 20 in a closed position. Theflaps 54 can also assist users in moving thecontainer 20 from one operating state to another. Theflaps 54 can also serve to ventilate thecavity 46 of thecontainer 20. - A
flap 54 is a surface horizontally adjacent to theplate 24, but separated from theplate 24 by aside score line 55. The boundaries of theflaps 54 are often demarcated by substantially vertical 55 and substantially horizontal score lines 57. As discussed above, one ormore flaps 54 may be used to support and enhance the ability of theplate 24 to function as a hinge for thelid 28. Some embodiments of theflaps 54 can be configured to be further twisted or pushed in by the user to further secure thelid 28 in a closed position. Such twisting or pushing in may render thecontainer 20 undesirable for subsequent opening and refilling. - An embodiment of the
container 20 that uses aplate 24 need not include anyflaps 54, but a combination of oneplate 24 with oneflap 54 on each side is often desirable. Some embodiments of aseptic containers 20 (seeFIGS. 1 b and 6 j) will includeflaps 54 but noplate 24. - As illustrated in
FIG. 5 d, a flap angle 97 (the angle formed by theside score line 55 and a bottom score line 57) is often between about 35 degrees and about 70 degrees. - 5. Flap Bottom Score Lines
- Some embodiments of the
container 20 will include a flapbottom score line 57 that connects the bottom portion of theflap 54 to a portion of thebody 22 that is vertically higher than thebody hinge 56 and the innergroove score line 52. - In some embodiments of the
container 20, the bottomflap score line 57, thebody hinge 56, and the innergrove score line 52 intersect with each other as illustrated inFIG. 2 a. In other embodiments, either the flapbottom score line 57 or the side score lines 55 will not be long enough to intersect. - 6. Skid Locks
- Some embodiments of the
plate 24 can include one ormore skid locks 58 to facilitate the ability of users to stack thecontainers 20 on top of each other even if thelids 28 are closed. Skid locks 58 in conjunction with therim 34 serve to constrain the lower portion of thecontainer 20 allowing thecontainers 20 to be vertically stacked onto each other even when thelids 28 are closed. Skid locks 58 can be implemented into theplate 24 using a wide variety of different manufacturing processes. - The ability of
skid locks 58 to facilitate the stacking ofclosed containers 20 is illustrated inFIG. 9 a. - 7. Hinge Break
- As illustrated in
FIGS. 6 f and 6 i, some embodiments of theplate 24 may include ahinge break 45. The hinge break 45 can facilitate the transition functionality of theplate hinge 26. The hinge break 45 can also provide an opening in which thetab 30 can be pressed into when thetab 30 is in a fully opened position. For example, instead of thetab 30 point upwards inFIG. 2 b, thetab 30 could be pushed into the opening resulting from thehinge break 45. It can provide a way to secure thetab 30 in a position that will prevent thetab 30 from interfering with the use of thecontainer 20 while thecontainer 20 is being used. For example, in an embodiment of thecontainer 20 used for the purposes of storing and drinking beverages, thetab 30 can be secured in thehinge break 45 when the user is drinking from thecontainer 20. - In
FIGS. 6 f and 6 i, thehinge break 45 is a semi-circle cut out from theplate hinge 26. Many embodiments of theplate 24 will include differently shaped hinge breaks 45, differently positioned hinge breaks 45, or no hinge break 45 whatsoever. - 8. Reinforcement Member
- Some embodiments of the
container 20 that include aplate 24 may also include a reinforcement member 23 underneath theplate 24 that connects thelid 28 to theplate 24 and assists in the opening and closing of thelid 28. As illustrated inFIGS. 5 c and 5 d, the reinforcement member 23 can be part of the lid blank 104 that is mated, fixed, or fastened to the interior surface ofplate 24 on thesidewall blank 106. - 9. Ventilation Gaps
- Some embodiments of the container that include a reinforcement member 23 may also include one or
more ventilation gaps 29.Such gaps 29 facilitate the ventilation of thecontainer 20. Ventilation of thecontainer 20 can be particularly important in the context ofcontainers 20 used to hold beverages. The ventilation provided by theventilation gaps 29 is in a horizontal direction when thelid 28 of thecontainer 20 is closed. - 10. Additional Score Lines and Chevrons
- As discussed above, the purpose of the
plate 24 is to insulate thebody 22 from the magnitude of movement required to open and close thelid 28. A variety of additional score lines and/or chevrons can be used to further support the underlying functionality of theplate 24 and theflaps 54. Score lines, vertical creases, and chevrons can also be used to facilitate the ability of users to properly seal thelid 28 in a closed position by making it easier for users of thecontainer 20 to properly manipulate thecontainer 20. - The
plate 24 and its subsidiary components act to insulate thebody 22 of thecontainer 20 relative to the significant motion by thelid 28 while at the same time facilitating the ability of thelid 28 to move in a manner that is required to open, close, and seal thecontainer 20. Theplate 24 also serves to make the opening, closing, and sealing of the lid as easy as possible for users to achieve while providing users with the features of reliability and reusability. Different embodiments of body hinges 56, lid hinges 26, flaps 54, andother plate 24 subsidiary components can be incorporated into thecontainer 20. - 11. Insulation Layer
- Some embodiments of the
container 20 can include aninsulation layer 77 beneath theplate 24 and/or lid 28 (illustrated inFIG. 6 k with dotted lines because thelayer 77 is underneath the top surfaces of thelid 28 and plate 24). The primary purpose of theinsulation layer 77 is to insulate the material in thelid 28 from potential heat associated with the contents in thecavity 46 of thecontainer 20. However, theinsulation layer 77 can also help shape and structurally reinforce thelid 28 as it is opened and closed. Theinsulation layer 77 can be comprised of a variety of different materials, including but not limited to a heat laminated foam that is formed from a high density polyethylene, low density polyethylene, linear low density polyethylene, and/or oriented polypropylene. - A
lid 28 is the means by which acontainer 20 is closed and in some cases, sealed (such as the case with watertight or substantially watertight containers). In some embodiments, agrove 52 in thebody 22 helps secure thelid 28 when it is moved to a closed/sealed position. In other embodiments, aflange 59 is used. In some embodiments, both aflange 59 and aninner groove 52 shaped for the purposes of sealing thelid 28 are used. - Although the position of the
lid 28 determines whether thecontainer 20 is in a closed state/configuration or an open state/configuration, the change in the position of thelid 32 is not achieved through any structure change to thelid 32. To the contrary, it is the plate 24 (sometimes in conjunction with the flaps 54) that serve as the hinge upon which thelid 28 can be moved. In the example ofFIG. 2 a, thelid 28 moves by being rotated around theplate hinge 26 and thebody hinge 56. - In many embodiments of the
container 20, thelid 28 is substantially circular in shape and need not be very thick. In many embodiments of thecontainer 20, thelid 28 is substantially parallel to the surface on which thecontainer 20 rests when the lid is in a closed operating configuration/state. For example, in a typical beverage cup embodiment of thecontainer 20, thelid 28 is a closed position in substantially parallel to the to the ground surface on which thebase 40 of thecontainer 20 can rest. - The
lid 28 can be in an open position, a closed position, or in some instances, a partially open/partially closed position. In many embodiments of thecontainer 20, thelid 28 is integral to theplate 24, and theplate 24 is integral to thebody 22. Thelid 28 can be comprised of the same material as theplate 24 andbody 22. Examples oflids 28 illustrated inFIGS. 1 a-1 c, 2 a-2 d, 6 g-6 j, and 7 e.FIG. 5 c also illustrates examples of lid-related attributes such astabs 30 that are not covers 27, covers 27 that are nottabs 30,openings 32, vertical creases 25, debossed covers 27, and a connection to a reinforcement member 23 to assist in the opening and closing of thelid 28. - In some embodiments, the
lid 28 is thicker than other portions of the container. In other embodiments, theedge 51 of thelid 28 may be thicker than other portions of thelid 28. In still other embodiments, the thickness of thelid 28 is equal to the thickness of thewalls 42 of thecontainer 20. - The ability to machine to a separate lid blank 104 makes it easier to include a
lid 28 that is thicker than other portions of thecontainer 20. - 1. Edge
- Different embodiments of the
lid 28 can include a potentially wide variety of different subcomponents. However, one common function of thelid 28 is the ability to close thecontainer 20 and secure contents within thecontainer 20. One attribute of thelid 28 that can facilitate the ability of thelid 28 to secure a closed position is theedge 51 of thelid 28. Theedge 51 can also be referred to as alid edge 51. In many cup embodiments of thecontainer 20, thelid 28 is secured within aninner groove 52 of thecontainer 20. The geometric configuration of theedge 51 and theinner groove 52 can enhance the functionality of thelid 28. For example, in some embodiments, theedge 51 of thelid 28 includes one of a wide variety of wave rule shapes. The geometry of theinner groove 52 can similarly be configured to enhance the functionality of thelid 28.FIG. 8 d illustrates an example of alid groove 52 geometry that can be implemented in thecontainer 20. In many embodiments, theinner groove 52 will have a convex shape, and anangle 64 of about 30 degrees. In different embodiments, different shapes anddifferent angles 64 can be incorporated into theinner groove 52. - In many embodiments of the
container 20, it may be useful to treat theedge 51 of thelid 28 with a material stronger than the material comprising thelid 28 generally or even thecontainer 20 generally. For example, in the example of a cup comprised primarily of paperboard, it may be desirable to treat theedge 51 with polyethylene. In other embodiments, theentire lid 28 could be treated with polyethylene or some other material. - 2. Tab
- Some embodiments of the
lid 28 can include atab 30 which serves as a handle for opening and closing thelid 28. Different embodiments of thetab 30 can include a different number of score lines. In many embodiments, the number of score lines in thetab 30 will depend on whether thetab 30 is used to seal an opening 32 (seeFIG. 2 b) in thelid 28. As illustrated inFIG. 2 a, thetab 30 includes ascore line 48 at the base of thetab 30 as well as a score line at thesegment 50 of thetab 30 that transitions from a primarily horizontal orientation to a primarily vertical orientation. This allows thetab 30 to facilitate the sealing and closing of the opening 32 (which can also be referred to as an opening 32) as well as the opening and closing of thelid 28. In many beverage embodiments of thecontainer 20, an additional third tab score line 60 (seeFIG. 7 e) can be used to facilitate the ability of the user to push thetab 30 down into the opening 32 (also referred to as a passageway 32) so that thetab 30 does not interfere with the comfort of the user in drinking the beverage in thecontainer 20. In other embodiments, thetab 30 can be secured in thehinge break 45. - Returning to
FIG. 2 a, thetab 30 is fastened to thelid 28 at atab base 48. The location of thetab base 48 can depend on whether or not thelid 28 includes anopening 32. If thelid 28 does include anopening 32, then thetab base 48 is typically the innermost edge of theopening 32. If thelid 28 does not include anopening 32, then thetab base 48 is typically located close to the outermost edge of the top surface of thelid 28. - The
container 20 illustrated inFIG. 2 a includes both atab 30 and anopening 32. The shape of thetab 30 can vary widely, but the tip of thetab 30 should serve to facilitate movement by the user and the shape of the lower portion of thetab 30 will typically depend on the shape of theopening 32. - The
tab 30 can be located in a wide variety of different locations on thelid 28. InFIG. 5 c, thetab 30 is positioned closed to theedge 51 of the lid, midway between theopening 32 and theplate hinge 26. In many embodiments, thetab 30 will be oriented approximately 90 degrees differently than the illustration inFIG. 5 c, to allow thetab 30 to sit flush unto thelid 28 whencontainers 20 are nested together. - 3. Opening/Passageway
- Some embodiment of the
lid 28 will include apassageway 32 to selectively expose the contents of thecontainer 20. Thepassageway 32 can also be referred to as anopening 32 or amovable lid partition 32. Thepassageway 32 can be open, closed, and sealed without otherwise moving thelid 28. For example, in the context of a beverage container, thepassageway 32 can allow the user to drink the contents of the container 20 (through use of a straw or by simply tipping the container in close proximity to an open mouth) while thelid 28 remains in a closed position. Thepassageway 32 can be closed/sealed using thetab 30. Thepassageway 32 inFIG. 2 a is illustrated with a dotted line because thepassageway 32 is not visible. Thepassageway 32 inFIG. 2 a is filled up and sealed by thetab 30. The bottom portion of thetab 30 inFIG. 2 a from thetab base 48 to thefold 50 is substantially parallel to the bottom surface of thecontainer 20 and the top portion of thetab 30 from thefold 50 upwards protrudes straight upwards in the air where it can be most easily grasped. - The shape of the
opening 32 and of the portion of thetab 30 used to plug thepassageway 32, can vary widely from embodiment to embodiment. Some embodiments of thecontainer 20 can include more than onepassageway 32. For example, some embodiments of abeverage container 20 could include two ormore openings 32 for the insertion of straws. - Additional illustrations of the movement of the
tab 30 and theopening 32 covered by thetab 30, can be seen inFIG. 2 b andFIG. 7 e. -
FIG. 5 c shows a debossedcover 27 over anopening 32. The configuration illustrated inFIG. 5 c may be particularly desirable in the context ofcontainers 20 used in conjunction with warm beverages, such as hot chocolate, tea, coffee, etc. - In some embodiments of the
container 20, a peel-off metallic sticker can be used as acover 27 theopening 32. Some embodiments of thecontainer 20 will not involve use of acover 27, and instead the geometry of thecontainer 20 in conjunction with the fill height will eliminate the need for acover 27. - 4. Chevrons
- As illustrated in
FIG. 6 g, thelid 28 can also includechevrons 49.Chevrons 49 in the lid can serve a variety of purposes that relate to assisting users in closing and opening thelid 28. For example, as illustrated inFIG. 6 g,chevrons 49 can assist users in centering the application of force to thelid 28 in closing thelid 28.Chevrons 49 can also serve to increase the stiffness of thelid 28 as it is being pushed or pulled by a user. Thelid 28 of thecontainer 20 can be comprised of a wide variety of different materials or combinations of materials, as discussed with regards to thebody 22 and theplate 24. - 5. Lid Stiffener Score Lines
- As illustrated in
FIG. 6 h, one or more lidstiffener score lines 63 can be used to reinforce thelid 28 immediately to the interior of theedge 51. This can assist the sealing process, and make thelid 28 more durable (i.e. properly function after many openings and closings). - 6. Hinge Break
-
FIG. 6 i is the mirror image ofFIG. 6 f, with the hinge break being in the form a semi circle. As discussed above, thehinge break 45 is an optional component but it can perform a variety of functions. - 7. Vertical Creases
-
FIG. 5 c illustrates an example of vertical creases 25 in thelid 28 that serve the structurally strengthen thelid 28, particularly through the process of being opened or closed. - 8. Insulation Layer
- As discussed above with respect to the
plate 24, aninsulation layer 77 can also be positioned on the bottom of thelid 28 to insulate and strengthen thelid 28. - Different embodiments of the
container 20 can include a wide variety of additional elements/components. As discussed above, different score line configurations can be incorporated into thecontainer 20. In some embodiments, a tear back adhesive can be place on thelid 28 to facilitate the pulling open of thelid 28. The structure and shape of the lidchannel seat groove 52 can be modified to provide extra reinforcement analogous to that of a girdle. For example, additional structural components could be added to prevent thelid 28 from moving beyond a particular closed position. Components such aschevrons 49 can be placed at various locations of thecontainer 20 to enhance structural strength at those locations. As illustrated inFIGS. 1 b and 6 j, thelid 28 may not always be attached to aplate 24 or aplate hinge 26, but components such as aflange 59 can be added to assist the functionality of sealing thecontainer 20. - In some embodiments, an additional vertical body seam running up from the bottom of the
body 22 to the outermost portion of thelid 28 and the location of thetab 30 could be used to further strengthen thecontainer 20. In some embodiments, the vertical body seam can include a lateral tab to facilitate the opening and closing of thecontainer 20. - For embodiments involving the storage of food, the
flaps 54 can include a cold seal adhesive that is water based. Pressure from the fingers of the users can then form a bond that will enhance the ability of thecontainer 20 to satisfy specification 276.170 FDA compliance as it pertains to direct food contact with respect to aqueous and fatty foods. - Depending on the product that a
container 20 is designed to secure, thecontainer 20 can be configured in a variety of different states or positions. For example, in the context of abeverage container 20, thecontainer 20 can be in a fully closed and sealed position to minimize the ability of the beverage to escape from the container. An example of the fully closed and sealed configuration is illustrated inFIG. 2 a, where thelid 28 is closed and theopening 32 is also sealed by thetab 30 which can include a variety of score lines designed to facilitate the ability of thetab 30 to fill theopening 32. -
FIG. 2 b illustrates an example of alid 28 that is fully closed, but anopening 32 that is not blocked by thetab 30, permitting the beverage to be consumed, but otherwise limiting the ability of the beverage to be spilled. As illustrated in the Figure, thetab 30 is straightened out into a vertical or substantially vertical position as theopening 32 is unsealed. As discussed below with respect toFIG. 7 e, some embodiments of thetab 30 will include anadditional score line 60 designed to facilitate the pushing of thetab 30 into theopening 32 so that thetab 30 does not interfere with the drinking of the beverage through theopening 32. In other embodiments, ahinge break 45 is used to secure thetab 30. The transition fromFIG. 2 a toFIG. 2 b can occur solely with the movement of thetab 30. -
FIG. 2 c illustrates an example of alid 28 that is partially open. Although the position of theplate 24 inFIG. 2 c is identical to the position of theplate 28 inFIG. 2 b andFIG. 2 a because theplate 24 is fixed, thelid 28 is nonetheless not in a closed position. In many contexts, the filling or refilling of thebeverage container 20 is performed while thecontainer 20 is in the configuration ofFIG. 2 c. In some contexts, a user may drink from thecontainer 20 while in the state illustrated inFIG. 2 c. The transition fromFIG. 2 b toFIG. 2 c involves movement of thelid 28 but not the movement of theplate 24. -
FIG. 2 d illustrates an example of acontainer 20 in a state of maximum openness. The illustrated configuration can be highly desirable for the purposes of stackingempty containers 20 on top of each other. The illustrated configuration can also be desirable in the filling or refilling of thecontainer 20, and in some instances, such as trying to clear out a cup of the remaining portions of a milk shake, for consuming the contents of thecontainer 20. The transition fromFIG. 2 c toFIG. 2 d involves primarily the moving of theplate 24 from its substantially horizontal position to its substantially vertical position. -
FIGS. 8 a, 8 b, and 8 c also illustrate different operating states from different points of view. - Different embodiments of the
container 20 can include a wide variety of different positions, states, and operating configurations. - As discussed above, the transition from one operating state to another operating state can impact the shape of the
container 20 by impacting the shape of thebody 22 underneath thebody hinge 56. When thebody hinge 56 is moved forward to transition the container away from a fully opened state towards a fully closed state, the shape of thebody 22 of the container in the aggregate is impacted. The magnitude and nature of the shape change can be impacted by the geometry and configuration of the components used in the particular embodiment of thecontainer 20. The use of components such as aninsulation layer 77, the reinforcement member 23, and a variety ofnon-foldable score lines 72 can impede the magnitude of shape changes to thebody 22 of thecontainer 20 in the opening and closing of thecontainer 20. -
FIG. 7 a is a geometric diagram illustrating an example of a substantially circularprimary score line 61 comprised of a substantially circularinner groove 52 and a substantiallycircular body hinge 52. In many embodiments of thecontainer 20, this is the shape of thebody 22 when thecontainer 20 is in a fully open position. The shape is also illustrated inFIGS. 2 d (in contrast toFIG. 2 a), 7 c (in contrast toFIG. 7 d), 7 f (in contrast to 7 g), and 8 b and 9 c (in contrast toFIG. 9 a). -
FIG. 7 b is a geometric diagram illustrating an example of a substantially circularprimary score line 61 comprised of a substantially circularinner groove 52 and a substantiallystraight body hinge 56. In some embodiments where theprimary score line 61 is initially imprinted on a blank instead of being added on after the fused blank is shaped around the bottom blank 102, even in an open state, the shape ofcontainer 20 will be directionally closer toFIG. 7 b. However, with respect to embodiments involving aprimary score line 61 added after the fused blank is shaped,FIGS. 2 a, 7 d, 7 e, 7 g, and 9 a illustrate acontainer 20 that is substantially elliptical in shape because theplate hinge 56 is less curved than when in a fully open state. -
FIG. 7 c is a bottom plan view diagram illustrating an example of acontainer 20 with theprimary score line 61 illustrated inFIG. 7 a when thecontainer 20 is in a fully open state. -
FIG. 7 d is a bottom plan view illustrating an example of acontainer 20 with theprimary score line 61 illustrated inFIG. 7 b in a fully closed state. - In addition to the use of a
curved body hinge 56, the use of curved side score lines 55 can also have a substantial impact on the geometry of thecontainer 20, particularly in conjunction with the use of a reinforcement member 23 and alarger arc 41. As illustrated inFIG. 6 k, the curvature of theside score line 55 can match the curvature of thelid 28 allowing the top of thecontainer 20 to form acontinuous arc 79. -
FIGS. 9 a, 9 b, and 9 c illustrate examples of howsimilar containers 20 can be stacked. -
FIG. 9 a discloses astack 90 ofclosed containers 20. Skid locks 58 on theplate 24 are used to facilitate the stacking of thecontainers 20. Different numbers, locations, and configurations ofskid locks 58 can be used to facilitate the functionality ofcontainer 20 stacking. -
FIG. 9 b discloses astack 94 ofopen containers 20 in a perspective view from which the substantially circular shape of thecontainers 20 is clearly evidence.FIG. 9 c discloses asimilar stack 94 from a different view. - The ability to effectively stack
containers 20 can have important implications for how thecontainers 20 are shaped. For example, the reason why the bottom 40 of a disposable coffee cup has a smaller diameter than thelid 28 is because it is necessary to stack the cups. As discussed above, the timing in the manufacturing process by which theprimary score line 61 is machined into thecontainer 20 can have a significant impact on the shape of thecontainer 20. It is more difficult to stack cups when theprimary score line 61 is not substantially circular in shape when the cups are in fully open operating states. -
FIG. 3 a discloses an example of a method for opening acontainer 20 andFIG. 3 b discloses a mirror image ofFIG. 3 a for closing acontainer 20. In both flow chart diagrams, the flexing of theplate 24 and flaps 54 involves flexing thefoldable score lines 71, such as thebody hinge 56, theplate hinge 26, the side score lines 55 and the flap bottom score lines 57. - There are many different alternative embodiments for transitioning the
container 20 from a fully opened state and a fully closed state. As discussed above, different embodiments have a different number oftabs 30 located in different positions on the container.Chevrons 49 can be added in certain places to encourage users to press down on certain services rather than others. The geometries of the horizontal score lines and the thickness. Different coatings can be applied to different locations on the exterior surface of thecontainer 20 to encourage different user activities for opening and closing thecontainer 20. -
Different containers 20 can involve different components and different steps for the opening and closing of thecontainer 20. -
FIG. 7 e is a diagram illustrating an example of a top view ofcontainer 20 that is in a closed and sealed state. In this example of thecontainer 20, thetab 30 includes three score lines (48, 60, and 50) to facilitate the ability of a user to push thetab 30 down into the opening 32 (also referred to as a passageway 32) so that thetab 30 does not enter the users mouth or otherwise interfere with the consumption of the beverage. The illustration inFIG. 7 e also includes twoskid locks 58 to facilitate the stacking ofclosed containers 20 as illustrated inFIG. 9 a. -
FIG. 7 c is a diagram illustrating an example of a bottom view of acontainer 20 with a substantially circularprimary score line 61 when thecontainer 20 is in an opened state.FIG. 4 d is a diagram illustrating another example of a bottom view of acontainer 20 in which the primaryhorizontal score line 61 is not substantially circular in shape because thecontainer 20 is either in a closed position and/or thescore line 61 was machined into the applicable blank prior to the shaping of the applicable blank around thebottom blank 102. BothFIGS. 7 c and 7 d show thebase 40. - As illustrated in the Figures,
different base 40 configurations can be incorporated into different embodiments of thecontainer 20. The type of material used to comprise thecontainer 20 and the type of contents anticipated to be held in thecontainer 20 can influence the appropriate design of the bottom of thecontainer 20. -
FIG. 8 a is a diagram illustrating an example of a side view of acontainer 20. Thecontainer 20 inFIG. 8 a is in a similar operating state/configuration as thecontainer 20 inFIG. 2 d, but from a different perspective. In this position, the portions of thetab 30,lid 28, andplate 28 that are most exterior to thecontainer 20 form a substantially vertical line segment extending upwards from theexterior surface 42 of thebody 22. - Although the
lid 28 is substantially flat when closed, the curvature of thecontainer 20 does not appear substantially flat as a line segment in a side view of thecontainer 20 when thelid 28 is in a full upright position.FIG. 5 a illustrates only a small portion of thebody hinge 56, but the impact of thecurved body hinge 56 does manifest itself in the fact that thelid 28 is not a simply a straight line as is illustrated inFIG. 8 b. - As illustrated in
FIG. 8 b, as thelid 28 moves more closely to a closed position, the side view of thelid 28 takes on a more two-dimensional appearance. This occurs because the originallycurved body hinge 56 becomes more straight as thelid 28 andplate 24 move forward. -
FIG. 8 c is a diagram illustrating an example of a side view of an interior body surface that includes a lidchannel seat groove 52 to secure thelid 28 in a closed position. Different geometric shapes can be incorporated into thegroove 52. Additional structures can also be added to preclude thelid 28 from moving beyond an optimal closed position.FIG. 8 d illustrates a close up view of theinner groove 52, withFIG. 8 e illustrating an example of theinner groove angle 64, which in many embodiments is about 30 degrees. In other embodiments theangle 64 can range from as low as about 15 degrees to as high as about 65 degrees. -
FIG. 8 f is a diagram illustrating an example of a front view of acontainer 20 that is in a fully closed operating state. -
FIG. 8 g illustrates the different positions of thetab 30 as thecontainer 20 transitions from closed and sealed (FIG. 2 a), to closed and unsealed (FIG. 2 b), open lid/plate secure (FIG. 2 c), and fully open (FIG. 2 d). - As discussed above, the
container 20 can be manufactured in a wide variety of different ways using a wide variety of different tools. The materials used to manufacture thecontainer 20 will have a significant impact on the manufacturing processes used with respect to theparticular container 20. In the context of thedisposable containers 20, many embodiments of thecontainer 20 will be comprised primarily of some type of paper or paperboard. Various coatings and adhesives can be used to secure and/or strengthen certain portions of thecontainer 20. For example, thelid 28, theedge 51 of thelid 28, or other parts of a disposable container could be coated with polylactic acid (PLA) or some other type of material. Disposable embodiments ofaseptic containers 20 will necessarily include significant materials in substitution of or in addition to paperboard-type material. - As discussed above with respect to
FIGS. 4 a-4 b andFIGS. 5 a-5 d,containers 20 can be manufactured through the assembly of blanks. Blanks comprise flat pieces of material capable of being further shaped, such a paperboard-type material as well as plastics. - Many embodiments of the
container 20 will involve either a 2 blank manufacturing process (SeeFIG. 4 a) that comprises a top blank 100 comprising the entire surface of thecontainer 20 except for the bottom blank 102 which comprises thebottom surface 48 and/orbase 40 of thecontainer 20. - Other embodiments will involve a 3 blank configuration (See
FIG. 4 b), with alid blank 104 and a sidewall blank 106 comprising the portions of the container that would be comprised of the top blank 100 in a 2 blank configuration. - In different embodiments of the container, different processes can be performed on the
container 20 when it is in the form of blanks, while other processes are performed after the blanks have been fused together and/or shaped at least partially into the form of the container. In many embodiments of the container, theprimary score line 61 is not machined into the top blank 100 (2 blank configuration) or onto the sidewall blank 106 (3 blank configuration) until after the applicable blank has already been shaped around thebottom blank 100. By machining the primary score line 61 (which is the substantially horizontal score line which comprises thebody hinge 56 and the inner groove 52) after the blanks have been shaped, theprimary score line 61 can maintain a substantially circular shape and the overall structural integrity of thecontainer 20 is enhanced. In some embodiments, theprimary score line 61 can be machined directly into the applicable blank. In still other embodiments, multiple elements can be machined into a substantially shapedcontainer 20 rather than the flat blanks. - Paperboard blanks can be prepared in a variety of different ways that involve either punching or cutting a roll of material such as paperboard or plastic. Blanks can be formed from a roll that is subject to a coating/lamination process to reinforce certain areas of the
container 20, a print process for displaying indicia such as words or graphics on thecontainer 20, a slitting process, and then a blanking or punching machine that results in the prepared blanks. Many paperboard embodiments of thecontainer 20 can be machined from either pre-printed, pre-punched blanks, and/or optional pre-printed roll stock - A variety of different machines can be used to actually cut or punch the blanks. Rotary dies, RP rotary dies (which is sometimes referred to as crossover technology), steel-rule die cutting, solid steel blanking dies, and other suitable machines can be used. It is often desirable to avoid using tools that avoid metal to metal contact that provide a clean cut, eliminating the standard crush-type cut. Thus RP rotary dies (which can also be referred to as “Bernal” rotary dies) are often desirable. Use of a shear-type cut can reduce or eliminate chaff, slivers, ragged cuts, and other undesirable outcomes that result from a more punch-type approach.
- Many manufacturers prefer solid-steel blanking dies however tools are not well suited in many embodiments of the
container 20 for embossing, forming, and creasing/folding elements into thecontainer 20. The quality of the cut and the defects in the printing/blanking web registration can shut down a manufacturing process and render the machining of thecontainer 20 with the use of a solid-steel blanking die impracticable in some but not all embodiments of thecontainer 20. - Many different machines can be used in the process of fusing the blanks together and shaping the
container 20. Roll stands, printers, roll feeders, heating applications, pressure applications, folding applications, and other tools can be used to fuse the blanks together. In a 3 blank embodiment, thelid blank 106 and the sidewall blank 104 are typically fused together before any shaping occurs. The fusing of blanks with the bottom blank 102 typically occurs simultaneously with the shaping of either the top blank 100 or the sidewall blank 106 that has already been fused to thelid blank 104. - A variety of different tools and processes can be used in forming/shaping the
container 20. - Blank feeders, transfer turrets, shuttle table, hoppers, timing belts, bottom feeders, forming stations, mandrel turrets, bottom reformers, sealers, pre-heaters, heating stations, incurl stations, top curl stations (in some instances 3 top curl stations are used), finishing stations, rimming turrets, folding stations, tamper/lubricating stations, folding plates, clamping bars, shell distributors, rotating nozzles, calibration stamps, vacuum nozzles, and other devices are used to shape either the top blank 100 or the fused blank (comprising the
sidewall blank 106 and the lid blank 104) around thebottom blank 100. - Blanks can be precisely positioned and tightly wrapped around the folding mandrel. The design of some cup embodiments of the
container 20 allows for thebody 22 wrapping with the punched and drawn cup bottom inserted prior to sidewall sealing or optional insertion of the cup bottom after the side wall sealing. Sealing of the side-seam and bottom seam can be completed by utilizing flame, hot air or ultrasonic heating. Sealing parameters related to temperature, pressure and registration are important within the forming process. The container shells (the shaped containers 20) can be designed to facilitate easy transfer between multiple turret stations positioned on the cup forming machine. - In many embodiments of the
container 20, there are processes performed on thecontainer 20 after thecontainer 20 is fully shaped. For example, it is often desirable for the process of top curling the rim 34 (which in some instances can involve 3 iterations of curling stations) and the machining of theloop 61 can both be done after thecontainer 20 is fully shaped. - The partially finished
container 20 can be transferred to the top curl turret, incorporating multiple stations to form thetop curl rim 34, lubrication, pre-curl, finishing curl and calibration. -
FIGS. 4 a and 4 b provide two examples of a method for manufacturing acontainer 20.FIG. 10 a provides a third example. - At 300, blanks are cut. This typically involves a rotary die or an RP rotary die. The number of configurations of blanks cut per
container 20 can vary from embodiment to embodiment. - At 302, a sidewall blank 106 can be top load fed onto a continuous motion conveyer. This can include a rotary pick and place feeding module that is seamlessly integrated with the
container 20 forming machine. Thesidewall blanks 106 can pass through the rotary pick and place module that includes lid hopper stations where the rotary pick motion can place the lid blank 104 in alignment with thesidewall blank 106. - At 304, the side wall blank 106 is fused to the
lid blank 104. This process can include low-density polyethylene heating and pressure technology. Forcontainer 20 embodiments involving cups for hot beverages, the inner surface of the sidewall blank 106 can be lined with a thin layer of polyethylene on the top and bottom surfaces. When thesidewall blank 106 and the lid blank 104 are fused together, the aggregate package structure can have greater strength and stability. The use ofseparate lid blanks 104 andsidewall blanks 106 has several advantages, including: (1)lid 28 staining/wicking; (2) cup stacking after filling; (3) strengthening thelid 28 generally and against humidity specifically; and (4) reduction of waste/scrap because moreaggregate containers 20 can be fit into less roll sheets. - At 306, the fused blank is shaped into a shell around the
bottom blank 102. This process usually involves both heat and pressure. - At 308, the bottom blank is secured within the bottom portion of the shell (either the shaped top blank 100 or the fused lid blank 104 and sidewall blank 105).
- At 310, the
primary score line 61 is machined into thecontainer 20. This step can be immediately preceded but is typically followed by the curling of therim 34. In some embodiments, three top curl stations can be used to curl therim 34. - Then the process ends.
-
FIG. 10 b is a flow chart diagram illustrating an example of a process that can be used to manufacture thecontainer 20. - At 320, the bottom blank 102 is heated. This can involve the use a mandrel turret to index the bottom blank 102 into a bottom re-former station where the bottom skirt is heated and re-formed into a shape more suitable for wrapping.
- At 322, the edges of the top blank 102 or a fused blank (the
sidewall blank 106 and the lid blank 104) are heated. This can be accomplished through the use of a transfer turret that indexes the sidewall blank 106 into a sidewall sealer and bottom preheat station where the edges of theblanks - At 324, the top/fused blank is wrapped around the bottom blank 100 forming a shell. This can be accomplished using a transfer turret to index the sidewall blank 106 into the folding station, releasing the blank after the lower clamp clamps the blank against the mandrel. The mandrel turret can index the bottom blank 102 into the folding station. The folding wings can wrap the
sidewall blank 106 around the bottom blank 102, forming the cup shell. The mandrel turret can then index the shell to the bottom heat station. - At 326, the bottom area of the shell is heated. This can involve heating the inside skirt of the bottom blank 102 and transporting the shell to the bottom incurl station.
- At 328, the bottom blank 102 is heated.
- At 330, bottom blank 102 is moved downward in the shell.
- At 332, lubricant (typically vegetable oil) is applied to the outside of the shell.
- At 334, the bottom edge of the shell is curled over the bottom skirt of the bottom blank 102. This can be done through the use of a bottom incurl station where the bottom edge of the
sidewall blank 106 is curled over the bottom skirt of the bottom blank 102. - At 336, the bottom is finished, knurled, and squared. A mandrel turret can index the shell to the bottom finishing station where this process is performed.
- At 338, the shell is moved pneumatically. This can be done using a mandrel turret that indexes the shell to the rimming turret, where the shell is pneumatically removed from the mandrel and transferred to the rimming turret.
- At 340, the shell is pushed down a pocket 340. The shell is indexed from the rimming turret to the tamper/lubricator station.
- At 342, lubricant is applied to the top of the shell.
- At 344, the first curl is applied to the top of the shell. In some embodiments, there can be three iterations of curling the
rim 34 before therim 34 is finished. - At 346, the
rim 34 is finished. - At 348, the
primary score line 61 comprising abody hinge 56 and aninner groove 52 are formed in thecontainer 20. - Then the process ends.
-
FIG. 10 c is a flow chart diagram illustrating an example of a process for manufacturing thecontainer 20. - At 350, the fused blanks (
blanks 104 and 106) are fanned. This can involve jacket blanks (segments) that are placed in a blank hopper with the printed side facing down. The segments are fanned using an air blast to prevent sticking - At 352, the fused blank is pre-folded. Pre-folding can be applied to the side of the blank that lies inward after being rolled.
- At 354, the fused blank is heated. The seam surface of the fused blank can be heated at the same time in which the pre-folding process at 352 is performed since the two dies of the blank are different.
- At 356, the fused blank is subjected to a final folding process. This occurs before the clamping bar closes on the side seam area.
- At 358, the bottom blank 102 is positioned with respect to the fused blank. The shell is taken off the folding turret in an upper vertical position. The clamping bar opens and the pusher moves the shell off the folding mandrel. The shell is then moved to the shell distributor.
- At 360, the bottom portion of the fused blank is heated and the bottom blank 102 is heated. This occurs after the
container 20 bottom is brought together with the shell. - At 362, the bottom shell is incurled and sealed into the shell of the fused blank.
- At 364, lubricant is sprayed by a rotating nozzle to aid the top curl processing.
- At 366, the upper edge of the
container 20 is preformed. This will ultimately become therim 34. - At 368, the
rim 34 is curled. The process can involve multiple curl processes. In some embodiments, there are three top curl stations for curling therim 34. - At 370 the
container 20 is calibrated using a calibration stamp. - At 372, the
primary score line 61 is machined into thecontainer 20. As discussed above this involves theinner groove 52 and thebody hinge 56. In many embodiments, theprimary score line 61 is circular or substantially circular in shape while thecontainer 20 is in an open position. - Then the process ends.
- As with any product, the design features of the
container 20 are impacted by the manufacturing process and tooling used to manufacture the container. The process can be performed using a variety of different machine tools known in the prior art. In a preferred embodiment, containers are produced using machine tools substantially similar to those of the prior art. In particular, the infrastructure below the table need not be changed in order to support some relatively modest functionality modifications above the table. -
FIG. 10 h is a diagram illustrating an example of amachine tool configuration 500 and various tool components that can be used to manufacture thecontainer 20.FIG. 10 d is a flow chart diagram illustrating an example of a process flow for manufacturing thecontainer 20 that utilizes thetool configuration 500 illustrated inFIG. 10 h. ThusFIGS. 10 h and 10 d relate to each other. -
Steps 400 through 430 can be performed using a blank feed paper cup machine.Steps 432 through 460 can be performed using a tab lid applicator machine. The various tooling components/stations machines that can be used to manufacture thecontainer 20 are collectively referred to as atool 500. - At 400, the bottom blank 102 is cut using a bottom
maker tool component 524.FIG. 5B illustrates an example of a bottom blank 102. The shape of the bottom blank 102 will depend on the shape of the bottom 40 portion of thecontainer 20. In many instances, the bottom blank 102 will be circular shaped, but other geometric shapes are possible. - At 402, the side wall blank 106 is fed into the tool using a blank
conveyer tool component 520. - At 404, the side wall blank 106 is transferred using a blank transfer
turret tool component 522. - At 406, the edges of the side wall blank 106 are heated and reformed using a
sidewall sealer 523. This is done to facilitate forming a shall 108 (mating one edge of the sidewall blank 106 with itself) out of the side wall blank 106 (in alternative embodiments involving only 2 blanks instead of 3, the top blank 100 is substituted for the sidewall blank 105 throughout this process) as well as to facilitate bonding with the bottom blank 102. In an embodiment of thecontainer 20 that involves a bottom 40 elevated off the ground by a circular ring base, the bottom blank 102 is shaped into that base. - At 408, the
sidewall blank 106 is wrapped around the shaped bottom blank 102 on thesidewall sealer 523. The contact areas of both have been pre-heated at 404.FIG. 10 e illustrates an example of a sidewall blank 106 being wrapped around the shapedbottom blank 102. - At 410, the bottom seal area of the
shell 108 is heated by a firstbottom heat station 518. At 412, the bottom seal area of theshell 108 is heated a second time by asecond heat station 516. - At 414, the bottom edge of the
sidewall blank 106 is curled over the bottom blank 102 skirt (the circular ring forming the future base of the container 20). This is done using abottom incurl station 515.FIG. 10 f illustrates an example of a curled edge at the skirt. - At 416, the bottom 40 is finished, knurled, and squared using a
bottom finish station 514. The bottom is comprised of the bottom blank 102 and the fused areas of the sidewall blank 106 that are permanently mated together.FIG. 10 g illustrates an example of a bottom 40 that is finished, knurled, and squared. - At 418, the
shell 108 is moved. This is preferably done pneumatically (air suction/vacuum) although other techniques could also be utilized. At 420, theshell 108 is then pushed down a “female” pocket to secure theshell 108 for the next step in the process. - At 422, a
tamper lubricator 525 applies lubricant to the top of theshell 108 to prepare for curling therim 34 of thecontainer 20. In some embodiments, therim 34 is curled twice (curled then finished). In other embodiments, therim 34 is curled three times (curled, finished, and calibrated). - At 424, the first curl is applied by a first
rim curl station 526. - At 426, the second curl is applied by a second
rim curl station 529. - At 428, the third curl (which is optional) is applied by a third
rim curl station 531. Therim 34 is referred to above and illustrated inFIGS. 8 a-8 g. - At 430, the shell is moved pneumatically to the next step in the process, moving the
shell 108 from the blank feed paper machine (steps 400-430) to the tab lid applicator machine (steps 432-462). - At 432, the
shell 108 is turned 180 degrees using aninverter turret 532. At 434, theshell 108 is pneumatically moved. At 436, theshell 108 is pushed down “female” pocket for subsequent processing. - At 438, a
tamper station 513 is used to apply lubricant in theshell 108. - At 440, the first grooving of the
primary score line 61 is performed by afirst grooving station 512. At 442, the second grooving of theprimary score line 61 is performed by asecond grooving station 510. Thescore line 61 is formed around the circumstance of thecontainer 20. The grooving of bothstations container 20 remains secured within the female pocket of the turret machine. Theloop 61 is comprised of thebody hinge 56 and theinner groove 52 are discussed above, and illustrated inFIGS. 7 a-7 d andFIGS. 8 a-8 f. - At 444, an
orientor 509 is used to orient theshell 108 for subsequent processing. - At 446, a lid hole die 502 is used to punch a hole in the lid stock for the subsequent creation of the
lid blank 104. - At 448, a
tab 30 is attached to the lid stock by alabel application area 503. - At 450, a lid scoring die 505 is used to score the lid stock.
- At 452, a lid blanking die 506 is used to cut the lid blank 104 from the lid stock.
- At 454, a
lid transfer turret 507 is used to transfer thelid blank 104 for mating the lid blank 104 with theshell 108 - At 456, a
lid heater 508 is used to heat the lid blank 104 to prepare for mating the lid blank 104 with theshell 108. - At 458, the
shell 108 is heated to prepare theshell 108 for mating with thelid blank 104. - At 460, a
lid sealing clamp 533 is used to fuse the lid blank 104 to theshell 108. - At 462, a container blow off
tool 533 is used to pneumatically move thefinished container 20. - The process then ends, and the
container 20 awaits subsequent shipping to customers. - Different embodiments of the
container 20 can involve different combinations and configurations of components and subcomponents. Most of the claim elements below in Table 1 below are optional, and such elements may be totally absent from particular embodiments of the container or even entire container categories. -
TABLE 1 Index of component element numbers Element Number Name Description/ Comments 20 Container A device that has the capacity to contain contents. Examples of containers include cups, such as coffee cups, other forms of non-aseptic cups, aseptic cups, or a virtually limitless variety of other containers (including but not limited to containers that have nothing to do with food or beverages). Different embodiments of the container can be comprised of different material compositions and different component and subcomponent configurations. All containers 20 must include abody 22 and alid 28. Allother components are potentially optional, depending on the particular embodiment of the container 20.22 Body A portion of the container 20 that includes thecavity 46. The body 22 is the portion of thecontainer 20 thatmoves the least when the container 20 changes from anoperating state of open to an operating state of closed, and vice versa. 23 Reinforcement A surface area that is part of the lid blank 104 that is Member connected to and reinforces the portion of the sidewall blank 106 that becomes the plate 24.24 Plate A portion of the container 20 that acts as an interfacebetween the lid 28 (which is used to open and close the container 20) and the body 22 (which provides for the cavity 46 and the capability of “containing”something). 25 Vertical Crease Straight score lines on the lid 28 used to reinforce thelid 28.26 Plate Hinge A hinge between the plate 24 and thelid 28. Theplate hinge 26 helps facilitate the transition of the lid 28 froman operating status of open to an operating status of closed, and vice versa. Embodiments of the container 20 that do not include a plate 24 do not include aplate hinge 26. 27 Cover A surface area 27 that covers thepassageway 32. Insome embodiments of the container 20, thetab 30 isthe cover 27. In other embodiments, thecover 27 isseparate and distinct from the tab 30 of thecontainer 20. 28 Lid A moveable surface that is capable of sealing the cavity 46, and closing the container 20. The movement of thelid 28 is what changes the operating state of thecontainer 20 between a state of being open and a stateof being closed. 29 Gaps Small openings in reinforcement member 23 of the lid blank 104 that can serve as horizontal ventilators for the container 20.30 Tab A portion of material connected to the lid 28 that canbe pulled by a user to open the container 20. In someembodiments, the tab 30 is used to seal or unseal apassageway 32 in thelid 28 of thecontainer 20. Inother embodiments, the tab 30 is totally unrelated to theopening or closing of the passageway 32.31 Dimple An extrusion extending outward or inward from the external surface of the container 20. Adimple 31 canbe formed by embossing, debossing, or some other process. Dimples 31 can provide a variety of functionsthat enhance the ability of users to grasp or use the container or to insulate a user from the temperature of the contents within the container 20. For example,dimples 31 can be serve as a built in sleeve for a coffee cup, allowing the drinker to hold a cup of hot coffee without any intervening sleeve. 32 Passageway An opening in the container 20 that is typically located(“opening”) in the lid 28. In many embodiments thepassageway 32can be opened or closed while the lid 28 remains in aclosed position. For example, the passageway 32 in thecontext of a cup can be used to drink from the cup even though the lid 28 is in a closed position. Liquid in thecup can pass through the passageway 32 directly orthrough a straw placed within the passageway 32. Thepassageway 32 can also be referred to as an opening.33 Dimple Group A grouping of individual dimples 31.34 Rim An upper edge of the body 22 of thecontainer 20. The(“top curl”) rim 34 can also be referred to as a top curl. In many instances, the rim 34 is a reinforced exterior surfacerepresenting the highest vertical position of the body 22. The horizontal plane of the rim 34 is oftensubstantially parallel to the lid 28 when thelid 28 is ina closed and sealed position. The horizontal plane of the rim 34 is also often substantially parallel to thebase 40 of the body 22.36 Headwall A portion of the body 22 that is below therim 34 but(“head-wall” or above the substantially horizontal score line 61 (the “head wall”) score line that can comprise the body hinge 56 and theinner groove 52). The head wall 36 (which can also be referred to as a headwall 36). 38 Support score Score lines in the body 22 of thecontainer 20 thatlines structurally support the lid 28 and plate 24 (if present).Support score lines 38 can be oriented in a horizontal manner or in a vertical manner. Support score lines 38 can be referred to as “plate support score lines” in embodiments where located below the plate 24 and “lidsupport score lines” in embodiments where there is no plate 24.39 Bottom interior An internal surface in the container 20 that is thesurface bottom of the cavity 46. The bottom interior surface(“ Interior 39 is often substantially flat and substantially parallel Base”) with the ground when the container 20 rests on a flatsurface. In some embodiments, the interior base 39 iselevated to further separate the contents of the container 20 from the surface on which thecontainer 20 rests. 40 Bottom exterior An exterior surface at the bottom the container 20. Insurface many embodiments, the bottom 40 is substantially flat. (“Exterior In embodiments of the container 20 in which theBottom”) interior base 39 is elevated, the exterior bottom 40 maybe in the shape of circular ridge, circular ring (i.e. skirt) or some other hollow geometric shape. 41 Rim Arc An angle representing the magnitude of the rim 34 withrespect to a horizontal cross section of the container 20.42 Wall The exterior surface of the body 22 that surrounds(except for the opening sealed by the lid 28) the cavity 46. Different embodiments of the container 20 caninvolve single-layered walls 42 or multiple-layeredwalls 42.44 Interior wall The interior surface of the body 22 that surrounds(except for the opening sealed by the lid 28) the cavity 46. 45 Hinge break A break in the plate hinge 26 orbody hinge 56.
