Abstract
A foldable air insulating sleeve for insulating beverage and food containers. The sleeve secures a cup and leaves an air pocket surrounding the cup providing thermal insulation and temperature regulation to allow the user to firmly grasp the cup. Support rings are placed medially on the inside of the sleeve to strengthen and prevent collapse of the sleeve. A lid is added to further insulate.
Description
FOLDABLE AIR INSULATING SLEEVE
1. Field of the Invention The present invention relates to insulating devices for beverage containers and more particularly, to insulating beverages and foods by using air as the insulator.
1. Field of the Invention The present invention relates to insulating devices for beverage containers and more particularly, to insulating beverages and foods by using air as the insulator.
2. Back2round and Related Art Disposable cups are routinely used in fast food and roadside restaurants to contain bot11 hot and cold drinlcs. Because such cups have relatively thin walls, insulation is poor. As a result, the cups in which hot beverages are served are often too hot to hold comfortably, and the outside surface of cups in which cold beverages are served often accumulate moisture also inalcing the cups difficult to hold, t11us causing the holder's hand and the table to become wet. In addition, cold drinlcs warm quickly and hot drinks lose heat rapidly.
In response to the need for a better beverage insulator, various types of disposable cardboard and paper sleeves have been used. The sleeves are sized to slide onto the outside of a beverage cup and are held in place by friction. The wide-diameter end of the typical beverage cup prevents the sleeve from sliding off the cup while the cup is being held. However, such devices are poor insulators because they are generally thin. Moreover, the close contact with the cup causes additional heat transfer to the outside of the insulator. Additional insulation is needed at the bottom of beverage cups because the fluid has been there for a longer period of time.
Also, such devices typically cover any printable material on the outside of the cup, resulting in a lost opportunity for advertising. While some transparent insulators have been created, they also lose effectiveness as insulators because of the close contact with the cups and the conductive material out of which they are typically made. Some of the more effective insulators are too bullcy and talce up too much storage space in small convenience stores, thus making the disposable cups too big to fit in most cup-holders. Another problem with most disposable cups is that since typical cups have narrow bases, they are unstable. Thus, there is a great need in the beverage industry for cups with better insulation and overall iinprovement.
To solve the problem of difficulty in gripping either hot drinks or cold drinlcs _ that accumulate moisture on the outside of the cup, some disposable cups include handles. Unfortunately, the problem with handles is that they are typically made out of paper or other sheet-lilce material and they lack sufficient strength to hold the cup in an upright position when the user is holding the cup by the handle. In other words, the weight of the cup can cause the handle to sag or tear such that the cup will tilt, spilling the beverage.
SUMMARY OF THE INVENTION
The present invention relates to insulating devices for beverage containers and more particularly, to insulating beverages and foods by using air as the insulator.
The preferred embodiment of the present invention involves a foldable air insulating sleeve configured to slidably receive and secure a beverage cup.
The foldable air insulating sleeve secures the cup in a manner that allows for a pocket of air to surround the cup. This poclcet of air insulates the beverage. The user can hold the ci.up by grasping the outer surface of the foldable air insulating sleeve, thus avoiding contact with a hot or wet cup surface. Because the bases of most disposable cups are narrower than their respective rims, more air and thus greater insulation is possible, especially towards the bottom of cups secured by the foldable air insulating sleeve. The wider base also gives the cup greater stability. Furthermore, the material out of which the foldable air insulating sleeve is made allows for advertisements or other printable material to be affixed on its outer surface. The foldable air insulating sleeve can be made out of many materials, including plastic or paper. The foldable air insulating sleeve is also foldable into a substantially flat position.
In this embodiment, the base of the cup rests on an inner base of the foldable air insulating sleeve. The imier base is coml.ected to an outer base, which is in contact with the outer surface and supports the entire sleeve-cup configuration. The space between the inner and outer base is filled with air and f-urther acts to insulate the contents of the cup.
In another embodiment, the foldable air insulating sleeve's outer base is in contact with the outer surface and supports the entire sleeve-cup configuration.
In yet another embodiment, the foldable air insulating sleeve's inner base has an opening through which the cup enters until the cup is either too wide and is stopped from further passage or until the cup meets the outer base of the foldable air insulating sleeve and is supported by it.
In even another embodiment, the foldable air insulating sleeve's outer base, while wider than the cup it supports, is narrow enough to fit into most cup holders.
In an additional embodiment, the foldable air insulating sleeve includes a lid that attaches to the top rim of the cup. The lid is substantially hollow, providing an air chamber, which further insulates the contents of the cup. When the foldable air insulating sleeve is used with food, the lid has no openings. When used with a cold drinlc, the lid has an opening through which a straw is placed. Finally, when used with a hot drink, the lid has a rounded mouth piece and a cap, the mouthpiece and cap being either separate or tethered.
While the methods and processes of the present invention have proven to be particularly useful in association with beverage containers, those skilled in the art will appreciate that the methods and processes can be used in a variety of different applications to insulate a variety of different ldnds of temperature sensitive substances (e.g. soups and other foods).
These and other features and advantages of the present invention will be set forth or will become more fully apparent in the description that follows and in the appended claims. The features and advantages may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. Furthermore, the features and advantages of the invention may be learned by the practice of the invention or will be obvious from the description, as set forth hereinafter.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to insulating devices for beverage containers, and more particularly, to insulating beverages and foods by using air as the insulator.
In the disclosure and in the claims the tenn "cup" shall refer to any container used to house consumable liquids and solids, or for insulating dishes full of food or liquid. Examples of cups include disposable cups, bucleets, food storage containers, leftover food container, casserole dish containers, small soup bowls and any other similarly shaped container from which one drii-Acs or eats that is in need of insulation.
By way of general description of the embodiments of the present invention, there is an air insulation barrier used to create a temperature gradient around the contents of a cup. The barrier may be an insulating sleeve that is placed around the exterior of a cup, or it may be a lid placed on the top of a cup. The barrier material may comprise paper, plastic, or a combination of the two. The invention as taught minimizes the amount of material needed to create the insulation barrier, as well as provide a user maximum choice in how to insulate the cup, making an insulating sleeve optional with the insulating lid, and vice versa. In addition, some embodiments of the present invention teach forming barrier shapes that can be folded to compact forms, and selectively expanded to a functional form. Finally, the invention teaches modifying the surface by applying material wit11 a high friction coefficient to improve the user's grip of the invention.
Referring to figures 1A - 5B illustrating two exemplary embodiments of a short insulating sleeve 5 wherein said sleeve can selectively receive a cup 10, the cup 10 and sleeve 5 having support rings 15 and forming an insulating air chamber with a temperature gradient from the outer surface of the sleeve 25 to the temperature of the cup. The support rings 15 support the weight of the cup 10 wliile sheathed by the sleeve 5, and provide the contact points between the cup 10 and the sleeve 5. In addition, the support medially positioned support ring 15 provides increased support to the user gripping the sleeve, thus preventing the sleeve collapsing when held, and preventing the sleeve's outer wall 25 from contacting the cup 10. The outer surface area 25 of the sllort sleeve is large enough to shield a user's hand from the surface of the cup10. Advantages of the short length of the sleeve are reduced manufacturing cost as well as the amount of storage space needed for several sleeves.
As illustrated in figures 1B and 4A, the sleeve may be folded to ininimize the profile of the sleeve. In addition, the sleeve may have indentations to allow the sleeve to fold along a desired axis.
Figure 2A illustrates a sleeve without a cup inserted therein. The support ring 15 can support is rigid enough to keep the sleeve in an open form even when a cup is not inserted into the center of the sleeve. A manufacturing tab or tab 30 is on the outer edge of the ring and connects the ring 15 to the outer surface 25.
Figure 2B's partially transparent view illustrates the insulating air chamber that forms between the cup 10 and the sleeve 5. Air is known as a superior insulation because of the difficulty gaseous molecules have in transferring kinetic energy.
Figure 3B illustrates a sleeve 5 with a surface area 25 that extends 35 beyond the support rings 15. This embodiment allows the rings 15 to be closer together while still providing a users' hand sufficient area to shield it from the temperature of the cup 10.
Referring now to figures 6A - 20B illustrating several embodiments of the insulating sleeve 5 with a plurality of structural beams 40 to support the weight of the cup 10. While the structural beams create more contact than other embodiinents described herein, the beams provide superior support, thus allowing the user to sheath a cup of a variety of weights. The cup may be large or small and contain food or drink, and an appropriately sized insulating sleeve can still support the weight of the cup 10.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to insulating devices for beverage containers, and more particularly, to insulating beverages and foods by using air as the insulator.
In the disclosure and in the claims the tenn "cup" shall refer to any container used to house consumable liquids and solids, or for insulating dishes full of food or liquid. Examples of cups include disposable cups, bucleets, food storage containers, leftover food container, casserole dish containers, small soup bowls and any other similarly shaped container from which one drii-Acs or eats that is in need of insulation.
By way of general description of the embodiments of the present invention, there is an air insulation barrier used to create a temperature gradient around the contents of a cup. The barrier may be an insulating sleeve that is placed around the exterior of a cup, or it may be a lid placed on the top of a cup. The barrier material may comprise paper, plastic, or a combination of the two. The invention as taught minimizes the amount of material needed to create the insulation barrier, as well as provide a user maximum choice in how to insulate the cup, making an insulating sleeve optional with the insulating lid, and vice versa. In addition, some embodiments of the present invention teach forming barrier shapes that can be folded to compact forms, and selectively expanded to a functional form. Finally, the invention teaches modifying the surface by applying material wit11 a high friction coefficient to improve the user's grip of the invention.
Referring to figures 1A - 5B illustrating two exemplary embodiments of a short insulating sleeve 5 wherein said sleeve can selectively receive a cup 10, the cup 10 and sleeve 5 having support rings 15 and forming an insulating air chamber with a temperature gradient from the outer surface of the sleeve 25 to the temperature of the cup. The support rings 15 support the weight of the cup 10 wliile sheathed by the sleeve 5, and provide the contact points between the cup 10 and the sleeve 5. In addition, the support medially positioned support ring 15 provides increased support to the user gripping the sleeve, thus preventing the sleeve collapsing when held, and preventing the sleeve's outer wall 25 from contacting the cup 10. The outer surface area 25 of the sllort sleeve is large enough to shield a user's hand from the surface of the cup10. Advantages of the short length of the sleeve are reduced manufacturing cost as well as the amount of storage space needed for several sleeves.
As illustrated in figures 1B and 4A, the sleeve may be folded to ininimize the profile of the sleeve. In addition, the sleeve may have indentations to allow the sleeve to fold along a desired axis.
Figure 2A illustrates a sleeve without a cup inserted therein. The support ring 15 can support is rigid enough to keep the sleeve in an open form even when a cup is not inserted into the center of the sleeve. A manufacturing tab or tab 30 is on the outer edge of the ring and connects the ring 15 to the outer surface 25.
Figure 2B's partially transparent view illustrates the insulating air chamber that forms between the cup 10 and the sleeve 5. Air is known as a superior insulation because of the difficulty gaseous molecules have in transferring kinetic energy.
Figure 3B illustrates a sleeve 5 with a surface area 25 that extends 35 beyond the support rings 15. This embodiment allows the rings 15 to be closer together while still providing a users' hand sufficient area to shield it from the temperature of the cup 10.
Referring now to figures 6A - 20B illustrating several embodiments of the insulating sleeve 5 with a plurality of structural beams 40 to support the weight of the cup 10. While the structural beams create more contact than other embodiinents described herein, the beams provide superior support, thus allowing the user to sheath a cup of a variety of weights. The cup may be large or small and contain food or drink, and an appropriately sized insulating sleeve can still support the weight of the cup 10.
Figures 6A through 7A show a short insulating sleeve that uses minimal material and provides minimal protection and insulation, while figure 7B
illustrates a long insulated sleeve that provides the contents of the cup greater insulation by covering more of the cup's surface area, as well as provide greater protection for the user's hand.
Figures 8A, lOB, 13B, 15B, 18B and 20B illustrate the insulating sleeve 5 folded to minimizing the storage area for the sleeve.
Figure 9B and 10A's transparent view of the cup 10 supported by the sleeve 's 5 structural beams shows in detail the insulating air chamber 20 formed between the outer surface of the sleeve 25 and the surface of the cup 10. Additionally illustrated is the extension of the sleeve 35 beyond the structural members 40 that allow the manufacturer to minimize the amount of material used in creating the structural members 40 while still providing the amount of surface area 25 needed to shield the user's hand from the cup. As illustrated, the sleeve may cover only a portion of the cup, or it may cover substantially all the cup.
Figure 11A illustrates round half-spheres as structural members. Using round half-spheres to create the insulating air chamber further minimizes the amount of material needed to create the sleeve as well as the simplicity of mating the cup and sleeve. Using round half-spheres allows the user to slip the cup into the sleeve while it is still partially folded, because there are no rings or members to align.
Figures 12A and 12B illustrate an embodiment where the structural members 40 are round half spheres that create the insulating air chamber 20 between the surface of the sleeve 25 and the surface of the cup 10. The length may be either short, covering only a portion of the cup's surface, or long covering substantially the entire length of the cup.
Figures 13A, and 14A through 15B illustrate a support structure comprising a tubular circle 40 along the sleeve's inner wa1145. The continuous contact between the structural member 40 and the cup 10 provides greater support to the cup 10 w11en the weight of the cup 10 is great. In addition, the continuous contact of the structural member 40 with the cup 10 creates an insulating air chamber 20 with less air moving between the cup 10 and the sleeve 5, thus providing insulation for the cup 10.
Figure 15A illustrates the teaching of the present invention wherein the number of structural support tubular rings 40 in increased with the length of the sleeve 5 to provide support for the user when gripping the sleeve 5 and cup 10.
Figures 16A through 17B illustrate slanted half-circle structural beams 40 as both short and long.
Figures 18A and 19A - 20B illustrate a flame structural beam 40, which provides increased multi-directional friction between the cup 10 and both a short and long sleeve.
Figures 21A and 21B illustrate an exemplary selection of cross-sections used as structural members 40.
Figure 22A illustrates an exemplary selection of shaped openings in insulating lids 50. The openings may be used for venting, passing a straw, or passing the contents of the cup. The insulating lid 50, described below, helps create another temperature gradient around the cup to help insulate the cup's contents.
Figure 22B illustrates an embodiinent of an insulating sleeve 5 with cup inside in an adaptor 55 adapted to fit the sleeve 5 into a cup holder (not shown).
Often, cup holders are sized so a cup fits snugly into the holder. If an insulating sleeve substantially increases the circumference of a cup, the user may be precluded from using the cup holder. By providing this einbodiment, the user may use both an insulating sleeve 5 and a cup holder.
Figures 23A and 23B illustrate the adapter 55 used to fit the sleeve and cup into a cup holder. The adapter provides a wide receiving end for receiving the cup and insulating sleeve. In addition, the adapter adapts the wide end to a narrower end to fit into a standard cup holder. It is anticipated that the narrower end can be adapted to fit any size cup holder, including widening the cup and sleeve combination, including widening the base to fit between two armrests 60.
Figures 24A through 24B illustrate adapter 55 widened to support 60 a drink and provide a working or resting surface in a theatre. Also anticipated are cup holders in cars, on airliners, at bars, as well as any other place commonly known in the art.
Referring now to figures 25A and 25B, there is illustrated an exemplary selection of layouts for structural beams 40 on an insulating sleeve wall 25 and insulating lid 50. In addition to those illustrated here, the present invention teaches any formation of structural beams commonly known in the art to provide rigidity and support to the sleeve and lid.
Figures 26A, 27A, 28A, and 29A illustrate an exemplary selection of insulating sleeves 5 with a cup 10 inserted into the sleeve 5, with the number of support rings 15 optimized to support the weight and size of the cup 10. As discussed above, the support rings 15 create an insulating air chamber 20 between a set of support rings 15 or between a support ring 15 and the base 65, that helps prevent the contents of the cup 10 from warming or cooling, as well as shield the hand of a person holding the cup 10. The insulating sleeve 5 may cover part or substantially all the side of the cup 10, depending on cost, manufacturing and storage considerations.
The tabs 30 provide a support to attach the support rings 15 to the insulation sleeve.
In addition, each ring makes a closed insulating air chamber 20.
Figures 26B, 27B, 28B, and 29B illustrate a folded insulated sleeve 5 as well as the positioning of the support rings 15 when folded. When the user unfolds the sleeve 5 and inserts the cup 10, all the support rings are simultaneously forced open thus allowing the cup to slide inside the sleeve. The present invention teaches a foldable insulating sleeve 5, modifiable to include the number of support rings 15 and an optional base 65 necessary to support the desired cup weight. As such, the number or arrangement and placement of support rings is taught by the present invention as such placement optimizes the performance of the sleeve 5.
Referring to Figures 30A - 35B which illustrate a cup 10 wit11 the insulating lid 50. The lid 50 is comprised of a top wall 70, a bottom wall 75, a brim clasp 80 that is releaseable coupleable to the brim 85 of the cup 10. The top wall 70 and bottom wal175 fonn the walls of the insulating air chamber 20, the bottom wall lying in the brim plane 90 so as to allow the cup 10 to be filled to capacity with content, and not have to save space for the insulating chamber 20. The lid 50 maximizes the storage capacity of the cup 10 by not filling the storages space with the insulating air chamber. However, the present invention also teaches minimizing the profile of the lid 50 by placing the insulating air chamber 20 below the brim plane 90.
As discussed above in figure 25B, structural beams 40 may be placed in the air chamber 20 of the lid 50 to improve its structural integrity, as well as provide additional support to the container as a whole. Additional support may be necessary when the lid 50 performs functions in addition to covering the cup. Such functions may be providing a defined opening 53 through which a straw 95 may be inserted. A
structural beain 40 would provide the necessary strength to prevent the allow the user to use a straw 95 without coinpromising the structural integrity of the lid.
An additional function may be to provide a content funnel 100 through which the contents of the cup may be funneled to the user's mouth. The content fiuuiel 100 may be part of the insulating air chamber 20, as shown in figure 33B, or the chamber 20 may end before reaching the fiuuzel 100 as shown in figure 34B. To prevent cooling and spills, the funnel has a cap 105.
Figures 3 1A and 31B illustrate another einbodiinent of the lid where structural supports 40 may improve the function of the bubble lid 110. Due to the bubble lid's 110 concave up shape, structural beams 40 enhance the functionality of the lid, allowing contents to extend above the brim plane 90, effectively increasing the storage capacity of the cup 10, while still being insulated and covered by the bubble lid 110. Again, the insulating air chamber 20 may be either on inside the lid to minimize the profile of the lid, as shown in figure 31B, or it may be outside on the outside of the lid to maximize the capacity of the cup. A defined opening 53 in the bubble lid 110 allows the user to insert a straw 95.
An exemplary embodiment shown in figure 35 illustrates a cup 10 with a flat lid 50 comprising an insulating air chamber 20 above the brim plane 90, and a brim clasp 80 coupled to the cup brim. This embodiment can be used for food storage, for example if a cllicken restaurant wanted to keep a patron's food warm until it was consumed, the chicken could be placed in the cup, the cup placed in an insulating sleeve, and the insulating lid placed on the top of the cup. The same situation could be made for hamburgers or any other food. In addition, the lid 50 may be connected to another lid to form a clamshell design and keep the food contents wann. In addition, the present invention teaches all combinations of the described arrangement.
Referring now to exemplary embodiments illustrated in figures 36A through 41B where show is a variety of insulating sleeve shapes that provide increased insulation for the cup. The shape of the sleeve may be substantially cylindrical, the walls of the sleeve being respectively parallel, thus creating larger insulating air chainbers 20 at the bottom of the sleeve than at the top, when the cup is tapered at the bottom. This shape provides improved insulation at the bottom of the sleeve where the contents of the cup will be for the longest period of time. Furthermore, the present invention teaches placing the support rings 15 in positions so as to minimize the amount of air circulating from the areas next to the empty cup, and areas insulating filled portions of the cup. In addition, the ring 15 provides the sleeve with increased structural support, thus preventing the sleeve from collapsing when gripped or held by a user. Here, the insulating sleeve 5 extends the entire length of the cup 10, so as to insulate substantially the entire cup 10. The substantially cylindrical sleeve also provides a wider more supportive base for the cup, thus preventing potential spills or tipping of the cup while in the sleeve.
Additionally, the present invention teaches the bottom of the sleeve may comprise either a base 65 on which the cup 10 rests, or a support ring 15 through which the cup 10 passes. When the sleeve 5 is substantially cylindrical, the rings 15 must remain concentric, but also compensate for the change of the cup 10 size.
Referring now to figures 42A through 52A, the present invention also teaches a tapered sleeve 5 so as to run substantially parallel to the walls of the cup 10, as show. Alternative exemplary embodiments where the insulating sleeve 5 covers different lengths of the cup 10, including approximately half of the cup's surface, three quarters of the cup's surface, and the entire length of the cup's surface. In addition, as discussed previously, the present invention teaches a support ring 15 that is flush with the top of the insulating sleeve 5, and an alternative embodiment that illustrates the sleeve 25 extending 35 beyond the top ring. Again, the insulating sleeve 5 may be foldable, thus minimizing the volume of shipping or storing several sleeves at one time.
Referring now to figures 52B through 58, an exemplary embodiment of a mouthpiece 115 is illustrated, with altenlative embodiments showing the beveled edge in figures 53B, 55B, and wide edge 125 in 57B. The size of the edge may be modified depending on the content of the cup, or to inlprove the user's comfort when putting the mouthpiece to the mouth. The mouthpiece 115 may provide an additional thermal barrier when used in combination with the sleeve 5 and lid 50 creating an additional insulating air chamber above the highest support ring 15. The mouthpiece may also provide a cooling surface when placed on the brim of a cup by allowing the hot contents of the cup to come into contact with a cool surface before being consumed by the user.
Thus, as discussed herein, the embodiments of the present invention embrace the field insulating devices for food or beverage containers. In particular, the present invention relates to insulating disposable cups by using air as the insulator.

Figure 9B and 10A's transparent view of the cup 10 supported by the sleeve 's 5 structural beams shows in detail the insulating air chamber 20 formed between the outer surface of the sleeve 25 and the surface of the cup 10. Additionally illustrated is the extension of the sleeve 35 beyond the structural members 40 that allow the manufacturer to minimize the amount of material used in creating the structural members 40 while still providing the amount of surface area 25 needed to shield the user's hand from the cup. As illustrated, the sleeve may cover only a portion of the cup, or it may cover substantially all the cup.
Figure 11A illustrates round half-spheres as structural members. Using round half-spheres to create the insulating air chamber further minimizes the amount of material needed to create the sleeve as well as the simplicity of mating the cup and sleeve. Using round half-spheres allows the user to slip the cup into the sleeve while it is still partially folded, because there are no rings or members to align.
Figures 12A and 12B illustrate an embodiment where the structural members 40 are round half spheres that create the insulating air chamber 20 between the surface of the sleeve 25 and the surface of the cup 10.
