In particular, although the following detailed description describes certain exemplary embodiments, it should be understood that other embodiments may take the form of other covers for a variety of containers, including bowls.
- For convenience and clarity, various features of embodiments of a reusable cover may be described herein by using directional adjectives such as inner, and outer. For example, “inner” may be used to describe the portions of a cover that face a container, and “outer” may be used to describe the portions of a cover that face away from the container. The use of these directional adjectives and the depiction of covers or components associated with covers in the drawings should not be understood as limiting the scope of this disclosure in any way.
- Throughout this disclosure various reusable container covers are illustrated. Referring to
FIG. 1 an isometric view of an embodiment of afirst cover 100 with acontainer 150 is depicted.First cover 100 may be representative of other reusable covers disclosed herein.First cover 100 may be any size and/or shape.FIG. 2 illustrates an isometric view of an embodiment offirst cover 100, in which a lower side offirst cover 100 can be seen. - It should be understood that while the embodiments described herein depict a cover for use with different containers, the same covers may also be utilized with plates (e.g., a relatively flat surface, or a receptacle with a shallow depth) or a variety of other serving, glass, kitchen, table, or dining ware. Thus, the covers could be applied on a plate. In some cases, a plate with food or other items disposed on the plate can be sealed. In addition, the covers could be used directly with or on food items. In one embodiment, a cover could be installed on a piece of fruit, vegetable, or other perishable item. In some cases, the covers could be installed on a substantially planar or flat surface of the food item, such as the exposed portion associated with a cut melon, a cut citrus fruit, a cut peach, a cut apple, etc., or any other cut fruit or vegetable or food item. In other cases, the covers could be installed along a generally round or curved surface of perishable items. Thus, the structural features of the covers may allow the covers to be used with many different types of surfaces and items.
- Thus, in different embodiments, the design of the covers may provide various structural features, characteristic, and properties to the covers. In some embodiments, a few of which are described below, the food covers may include a wide variety of designs. For example, as also shown more clearly in the exploded view of
FIG. 3 ,first cover 100 may include abase 110 and aflexible wall 120. Referring toFIGS. 1-3 ,flexible wall 120 may extend downwardly from and surround base 110 in some embodiments. In one embodiment,flexible wall 120 may define achamber 102 and anopening 104. In some embodiments,flexible wall 120 andbase 110 can be over molded with generous purchase for surface contact adhesion. In other embodiments, a weld, an adhesive, or another bonding agent may be also be used to join the components together. In cases where a welding process is used, the weld could be an ultrasonic weld or any other type of weld. - While
base 110 andflexible wall 120 may be generally circular in shape in some embodiments, they may include a variety of other geometries, some of which will be discussed below. For example,base 110 and/orflexible wall 120 may also have a cross-sectional shape that is round, square, triangular, or irregular. In some embodiments,base 110 and/orflexible wall 120 may have a variety of geometric shapes that may be chosen to impart specific aesthetic or functional properties tofirst cover 100. - In
FIGS. 1 and 2 ,first cover 100 is shown in an undeformed or initial state, wherefirst cover 100 has not been installed on or applied to a container.Flexible wall 120 andbase 110 have aninner surface 132 and anouter surface 130.Inner surface 132 corresponds to the inner region offirst cover 100. Whenfirst cover 100 is applied ontofirst container 150,inner surface 132 is the surface that faces towardsfirst container 150. In contrast,outer surface 130 faces away fromfirst container 150, when the cover is applied ontofirst container 150. - As shown in the exploded illustration of
FIG. 3 ,base 110 can include acentral portion 112 and aperipheral portion 114 in different embodiments.Central portion 112 may comprise a substantially flatinner surface 132 and/or a generally flatouter surface 130 in some embodiments. However, in other embodiments,central portion 112 may include any surface texture, including bumps, ridges, grooves, patterns, edges, undulations, and other non-flat features. - In some embodiments,
central portion 112 ofbase 110 may be joined toperipheral portion 114 ofbase 110. In different embodiments,central portion 112 andperipheral portion 114 may be a single piece or may comprise two distinct pieces. For example,peripheral portion 114 andcentral portion 112 may be a single, continuous piece, comprising the same material(s). In one embodiment,peripheral portion 114 andcentral portion 112 may be made of unitary construction, forming a single component, such thatperipheral portion 114 andcentral portion 112 are terms of reference for two regions ofbase 110. In other embodiments,peripheral portion 114 andcentral portion 112 may comprise two distinct pieces ofbase 110. InFIG. 3 ,peripheral portion 114 is joined along an outer periphery ofcentral portion 112, such thatbase 110 comprises a single piece. - Furthermore,
peripheral portion 114 can have aninner edge 117 that is associated with aperimeter 113 ofcentral portion 112, and anouter edge 118 that is disposed proximate toflexible wall 120.Outer edge 118 may also be associated with the outer periphery ofbase 110. In one embodiment,peripheral portion 114 may be a portion ofbase 110 that provides an area of joining, attaching, or otherwise adhering toflexible wall 120. As will be discussed further with respect toFIGS. 4 and 5 ,inner edge 117 may curve toward acentral region 125 ofcentral portion 112, whileouter edge 118 may curve away fromcentral region 125, forming a ridge 119 near the perimeter ofbase 110. - Referring to
FIGS. 1 and 2 , in some embodiments,outer edge 118 ofperipheral portion 114 ofbase 110 may be joined toflexible wall 120. In one embodiment,flexible wall 120 may be comprised of aring portion 126 and arim portion 127. In one embodiment,flexible wall 120 may extend away fromperipheral portion 114. As will be discussed further with respect toFIGS. 4 and 5 ,ring portion 126 may be attached toperipheral portion 114 in various ways. - In one embodiment,
flexible wall 120 may include curving or bent regions. For example, as illustrated inFIGS. 1-3 , in one embodiment,ring portion 126 andrim portion 127 may be joined to form a substantially perpendicular (approximately 90 degrees) angle. In other embodiments,ring portion 126 andrim portion 127 may be joined to form angles greater than 90 degrees or less than 90 degrees. In some embodiments,rim portion 127 may comprise a radial shape, and include anannular flange 300 that extends radially inward.Annular flange 300 ofrim portion 127 may form or help defineopening 104. In some embodiments, opening 104 may provide access tochamber 102 created by the contours ofinner surface 132 offirst cover 100. It should be understood thatring portion 126 andrim portion 127 may be a single, continuous material in one embodiment. - In addition, in some embodiments,
rim portion 127 offlexible wall 120 may include one ormore apertures 124 that may provide an improved sealing mechanism betweenfirst cover 100 and a container. Agroove 129 may also be formed along the outer perimeter offirst cover 100 for joiningfirst cover 100 withbase 110, as will be discussed further below. Furthermore, as shown inFIGS. 1-3 ,flexible wall 120 may include arelease tab 122.Release tab 122 will be discussed further with respect toFIGS. 17-18 . - While
base 110 and/orcentral portion 112 may be generally round or disc-shaped in some embodiments, in other embodiments,central portion 112 may include any geometry, including square, triangular, elliptical, oblong, or another regular or irregular shape. Furthermore, thoughbase 110 may be round in one embodiment,base 110 may also include regions of discontinuity, such that portions of the disc are absent, as shown inFIG. 3 . In one embodiment, agap 116 can be included inbase 110.Gap 116 may comprise different sizes or shapes, including a generally triangular, oval, square, or another irregular or regular shape. It should be understood thatgap 116 and the overall shape ofbase 110 may be designed to accommodate or provide improved contact with other portions or components offirst cover 100. For example, the shape and/or size oftab 122 offlexible wall 120 may correspond togap 116 in some embodiments. In other embodiments,tab 122 andgap 116 may differ. - It will be understood that the labels used herein such as
central portion 112,peripheral portion 114,ring portion 126,rim portion 127,tab 122,gap 116, andcentral portion 112 are only intended for purposes of description and are not intended to demarcate precise regions offirst cover 100. Likewise,outer surface 130 andinner surface 132 are intended to represent generally two sides offirst cover 100, rather than precisely demarcatingfirst cover 100 into two sides. - During use with various containers, reusable container covers may provide a seal between a container and the cover. In one embodiment, a reusable cover may form an annular sealing ring between a container and the reusable cover. Referring to
FIG. 4 , a cross-sectional view offirst cover 100 is depicted in the longitudinal direction, as indicated inFIG. 1 .FIG. 4 illustrates an embodiment offirst cover 100 in an initial, or undeformed configuration. The embodiment ofFIG. 5 illustrates the cross-sectional view offirst cover 100 fromFIG. 4 in its installed, or deformed, configuration. - As shown in
FIGS. 4 and 5 ,base 110 may be formed from any generally two-dimensional material that is formed into a three-dimensional geometry (e.g., a flat central portion and a curved periphery). The term “two-dimensional material” as used through this detailed description and in the claims refers to any generally flat material exhibiting a length and width that are substantially greater than a thickness of the material. Although two-dimensional materials may have smooth or generally untextured surfaces, some two-dimensional materials will exhibit textures or other surface characteristics, such as dimpling, protrusions, ribs, or various patterns, for example. Despite the presence of surface characteristics, two-dimensional materials remain generally flat and exhibit a length and a width that are substantially greater than a thickness. However, it should be noted that although portions ofbase 110 are formed from a generally two-dimensional material,base 110 may be configured with some thickness. For example, in the embodiment ofFIG. 5 ,base 110 can be associated with afirst thickness 560. In some cases,first thickness 560 can have a value in the range between 0.001 millimeters and 1 centimeter, to 2 centimeters. In other cases,first thickness 560 can have any other value. Additionally, it will be understood that the thickness ofbase 110 can be selected according to the desired size of the cover, and that the height and width ofbase 110 may have values that are substantially larger than the value offirst thickness 560. Furthermore, the thickness ofbase 110 can vary along various portions ofbase 110. For example, in one embodiment, one or more regions ofcentral portion 112 may be thicker thanperipheral portion 114, while in another embodiment, one or more regions ofperipheral portion 114 may be thicker thancentral portion 112. -
Base 110 may be joined toflexible wall 120 in various ways. In some embodiments, the structural features ofbase 110 andflexible wall 120 may provide a means for joining or helping to attach base 110 toflexible wall 120 to formfirst cover 100. For example, inFIGS. 4 and 5 ,ring portion 126 offlexible wall 120 includes afirst wall 430 and asecond wall 440. In some embodiments,first wall 430 and/orsecond wall 440 may extend upward fromrim portion 127.First wall 430 may be extend in a direction substantially parallel tosecond wall 440, and form the space or groove 129 (depicted inFIG. 3 ) betweenfirst wall 430 andsecond wall 440. The groove may be filled at least in part by anenclosed portion 460 ofperipheral portion 114 in one embodiment. Thus, in some embodiments,enclosed portion 460 may be an area or segment ofbase 110 that is inserted, covered, or otherwise joined toflexible wall 120 to formfirst cover 100. In other embodiments, a weld, an adhesive, or another bonding agent may be also be used to join the components together. In cases where a welding process is used, the weld could be an ultrasonic weld or any other type of weld. - Furthermore, in one embodiment,
ring portion 126 and a radiallyinner limit 441 ofrim portion 127 may be joined to form a substantially perpendicular (approximately 90 degrees) angle, whereinrim portion 127 extends radially inward.Annular flange 300 ofrim portion 127 may include a means of forming or creating an annular sealing ring betweenfirst cover 100 and a container in some embodiments. As shown inFIGS. 4 and 5 ,rim portion 127 includesannular flange 300 that can also define the shape ofopening 104.Annular flange 300 ofrim portion 127 may also include afirst side 470 that faces towardsbase 110 in the initial state and asecond side 472 opposite of thefirst side 470. - In
FIGS. 4 and 5 ,annular flange 300 is depicted in cross section as comprising afirst flange portion 410 and asecond flange portion 420.First flange portion 410 and/orsecond flange portion 420 may extend from the outer periphery offirst cover 100 towards acentral axis 439 offirst cover 100, which is depicted inFIG. 4 . Althoughfirst flange portion 410 andsecond flange portion 420 are individually labeled herein, it should be understood that they are two portions ofannular flange 300. In other words, in one embodiment,rim portion 127 comprises continuousannular flange 300, andfirst flange portion 410 andsecond flange portion 420 simply identify two areas alongannular flange 300. Thus,first flange portion 410 and/orsecond flange portion 420 should not be understood to refer to two distinct parts or components. - The width of
annular flange 300 ofrim portion 127 may vary in different embodiments. In some embodiments,first flange portion 410 may have afirst width 452, andsecond flange portion 420 may have asecond width 454, such that the width ofannular flange 300 is wider in some regions and narrower in other regions. In other embodiments, the width ofrim portion 127 may differ from what is shown inFIGS. 1-5 . - As noted above, in one embodiment,
rim portion 127 may help define a diameter ofopening 104. Thus, opening 104 may have afirst diameter 450, which as shown inFIG. 4 , can extend from afirst tip 462 offirst flange portion 410 to asecond tip 464 ofsecond flange portion 420.First tip 462 andsecond tip 464 may correspond to the radiallyinner limit 441 ofrim portion 126 in some embodiments. - It should be understood that the diameter of
opening 104 may expand asrim portion 127 is pushed away from its default configuration. Therefore,first diameter 450 may change significantly asfirst cover 100 is attached or joined to a container or other component, since this attachment results in a deformation of the default configuration. For example, in use, containers (such as a bowl) may have a diameter greater thanfirst diameter 450. As depicted inFIG. 5 , upon installation offirst cover 100 on afirst container 500, it can be seen that afirst container diameter 550 is greater thanfirst diameter 450 of opening 104 (inFIG. 4 ). It should be understood that whilefirst cover 100 is shown in cross-section for illustrative purposes, the container is depicted in a schematic side view. Whenfirst container 500 enterschamber 102,first flange portion 410 andsecond flange portion 420 ofrim portion 127 move inwardly (i.e., into chamber 102). The bending of rim portion 127 (includingfirst flange portion 410 and second flange portion 420) may permit the engagement of a container with a diameter greater thanfirst diameter 450. In other words, upon installation offirst cover 100 uponfirst container 500, opening 104 may increase in diameter to asecond diameter 552 that may be substantially similar tofirst container diameter 550 in some embodiments. - In order to accommodate
first container 500,rim portion 127 may bend upward, andfirst side 470 ofannular flange 300 may contactfirst container 500. As used herein, “upward” refers generally to a direction oriented alongcentral axis 439, sincecentral axis 439 may generally be associated with the vertical direction whencontainer 500 withcover 100 is placed on a horizontal surface in normal use. In other words, as shown in the cross-sections ofFIGS. 4-5 ,rim portion 127 may transition from being substantially perpendicular tocentral axis 439 in the initial state (FIG. 4 ) to being more parallel tocentral axis 439 in the deformed state (FIG. 5 ), assecond side 472 ofrim portion 127 contacts and/or slides againstsidewall 520 offirst container 500. - Thus,
annular flange 300 may engage withsidewall 520 offirst container 500 to provide a seal betweenfirst cover 100 andfirst container 500. In one embodiment,rim portion 127 may deform from its radial shape in the initial state ofFIG. 4 such thatannular flange 300 extends radially inward, and deflect axially upward towardbase 110 to help form an annular sealing ring aroundfirst container 500. - For example, as shown in
FIG. 4 ,first flange portion 410 ofrim portion 127 forms afirst angle 495 withring portion 126. In some embodiments,first angle 495 may be approximately 90 degrees. However, asfirst container 500 contacts rimportion 126,first flange portion 410 ofrim portion 127 bends upward, forming asecond angle 510 inFIG. 5 . In other words, whereasfirst flange portion 127 was substantially perpendicular with respect to ringportion 126 during the initial state ofFIG. 4 , inFIG. 5 first flange portion 410 has curved or deformed to formsecond angle 510 withring portion 126 that is less than 90 degrees. Similarly, second flange portion 420 (or other portions) ofrim portion 127 may bend or deform upward, transitioning from a substantially linear geometry along the horizontal plane, to a curved configuration. For example, inFIG. 4 ,second flange portion 420 forms athird angle 497 withring portion 126, while inFIG. 5 ,second flange portion 420 forms afourth angle 512 withring portion 126. It can be seen thatthird angle 497 is greater thanfourth angle 512. In some embodiments,fourth angle 512 may be significantly smaller thanthird angle 497. - Thus, as indicated in the examples above,
annular flange 300 may transition from a substantially flat or linear geometry to a curved geometry in different embodiments. As shown inFIG. 4 ,annular flange 300 may be substantially perpendicular with respect tocentral axis 439 in the initial state. However, upon contact with a container,annular flange 300 may bend such that at least a portion ofannular flange 300 extends into the direction defined bycentral axis 439. - It should be understood that
second angle 510 andfourth angle 512 may be similar in some embodiments or may differ significantly during application offirst cover 100 onfirst container 500. Thus, depending on the container type, the curvature of along various regions ofrim portion 127 may differ from one another upon installation on the container. Due to the flexible nature of therim portion 127, there may be a compressive force created betweenfirst container 500 andfirst cover 100 in some embodiments, as will be discussed further below with respect toFIG. 6 . - As shown in
FIGS. 4 and 5 , in some embodiments, asannular flange 300 deforms axially, opening 104 moves upward in an axial direction alongcentral axis 439. In other words, opening 104 is disposed nearer tobase 110 in the axial direction in the deformed state ofFIG. 5 than in the initial state ofFIG. 4 . The change in axial distance ofopening 104 relative to base 110 will be discussed further with respect toFIGS. 24-27 below. - The sealing or compression process may reduce or restrict air flow into
chamber 102 andfirst container 500 in some embodiments. It should be understood that while the sealing mechanism may reduce air flow, it may not entirely eliminate air flow in some embodiments. Once a user partially consumes food, such as fruits, vegetables, leftovers from various meals, or other food items, the user may wish to limit the amount of air or moisture the food is exposed to. However, user may have containers of varying sizes and dimensions. As described earlier, in order to provide a reusable cover that may be installed on multiple bowl sizes and types,first cover 100 includesflexible wall 120. Due to the structural features offlexible wall 120, includingrim portion 127,first cover 100 may be applied on a range of container diameters. In other embodiments,first tip 462 and/orsecond tip 464 ofrim portion 127 may remain in contact with asidewall 520 offirst container 500. In other embodiments, as discussed below, the edge ofrim portion 127 associated withfirst tip 462 andsecond tip 464 may curve or deform upward to various extents, and there may be greater or lesser contact betweenflexible wall 120 and a container. - Furthermore,
first cover 100 may include provisions for improving grip of the cover, as well as stability, particularly in stacking of containers utilizing the reusable covers disclosed herein (as will be discussed with reference toFIG. 16 ). InFIGS. 4 and 5 ,inner edge 117 andouter edge 118 ofperipheral portion 114 are depicted.Inner edge 117 rises up fromcentral portion 112 and meetsouter edge 118, which curves downward along the sides offirst cover 100 to joinrim portion 127 offlexible wall 120. Thus, in some embodiments, aridge 466 may be disposed along the outer border ofbase 110.Ridge 466 may exist along the entire border ofbase 110, or along a portion ofbase 110.Ridge 466 can be an undulation or bump or other formation that provides additional grip tofirst cover 100 for easier handling. In addition,ridge 466 may allow for greater stability during stacking of containers (seeFIG. 16 ). - Furthermore, in embodiments where
base 110 is substantially transparent, becauseperipheral portion 114 extends outward and along at least a portion of the sides offirst cover 100, any contents of a container sealed withfirst cover 100 can be visible not just from directly above, but may also be visible from other perspectives. In other words, the design ofbase 110 facilitates a greater visibility along the outer periphery, which may facilitate the identification of a container's interior contents. This can be particularly useful when containers are stacked or stored in compartmentalized areas (such as shelves in cabinets, or in refrigerators), and a user would otherwise need to remove the container to discern its contents. With this arrangement, a user may be able to identify the contents within a container without first removing the container from a refrigerator due to the transparency ofperipheral portion 114. -
FIG. 6 provides an illustration of an embodiment of the mechanism offirst cover 100 as it is installed on a container.First cover 100 is shown above asecond container 650 and athird container 600. Opening 104 offirst cover 100 has amaximum diameter 604, which corresponds to a configuration whererim portion 127 is approximately parallel withring portion 126.Second container 650 has asecond diameter 620 andthird container 600 has athird diameter 610. - In one embodiment,
first cover 100 may be configured to apply a minimum amount of cylinder stress or hoop stress to a container when installed, facilitating the formation of an annular sealing ring betweenfirst cover 100 and the container. The force exerted circumferentially along the sidewall of the containers may vary in different embodiments, for example with different sized containers. The hoop stress may allowfirst cover 100 to grasp or grip the sidewall of the containers in some embodiments. - In some embodiments, in order to provide the hoop stress necessary to form a seal, there may be a minimum contact region between
first cover 100 and a container. For example, assecond container 650 approaches opening 104 offirst cover 100, there may be a minimum area ofrim portion 127 that must make contact with the container in order to form a seal. InFIG. 6 ,minimum contact region 690 is disposed near radiallyinner limit 441 alongrim portion 127. In other words, there may be a minimum area ofrim portion 127 associated with the circumferential periphery ofrim portion 127 that is required to contact the container in order to provide the tension needed for formation of a substantially airtight seal. - Thus, in order to form a seal, there may be a minimum container diameter (as illustrated by second container diameter 620) associated with the exterior surface (e.g., a sidewall) of the container disposed along the mouth of the container. For example, to make contact with
minimum contact region 690 ofrim portion 127,second container diameter 620 is slightly larger relative tofirst diameter 450 ofopening 104. It should be understood that the minimum contact region extends all aroundrim portion 127.Second container diameter 620 is an illustration of the minimum container diameter needed to form a seal, as it is large enough for asidewall 658 ofsecond container 650 to contact with the necessary minimum contact region ofrim portion 127. - In other embodiments,
first cover 100 may include a maximum container diameter with which it can form a seal. However, it should be understood that while the minimum container diameter corresponds to the region of the container that is adjacent to amouth 656 ofsecond container 650, the maximum container diameter may correspond to the largest region of the container that enters or is engaged withfirst cover 100. For example, inFIG. 6 ,third container diameter 610 ofthird container 600 provides an illustration of the maximum container diameter that may be used withfirst cover 100.Third container 600 includes anouter lip 606 that extends beyond amouth 662. Due toouter lip 606, arim 608 ofthird container 600 extends farther outward relative to containers that do not include a lip. In some embodiments, whilerim portion 127 offirst cover 100 forms a seal with asidewall 660 ofthird container 600 further downward fromouter lip 606, the maximum size permitted for use withfirst cover 100 may be restricted by the diameter ofthird container 600 includingouter lip 606, as represented bythird container diameter 610. In one embodiment, the maximum container diameter may be substantially similar tomaximum diameter 604 offirst cover 100. - The maximum container diameter may be associated with a
maximum contact region 664, which extends outward fromsecond tip 464 towardring portion 126. Asthird container 600 approaches and enters opening 104 offirst cover 100,third container 600 makes contact with a radiallyouter limit 668 ofmaximum contact region 664. In other words, there may be a maximum area ofrim portion 127 offirst cover 100 which may contact a container, beyond whichfirst cover 100 may not form an adequate seal. In some embodiments, radiallyouter limit 668 ofmaximum contact region 664 is the area ofmaximum contact region 664 that is disposed closest to ringportion 126. It should be understood that the maximum contact region extends all aroundrim portion 127. In other embodiments,maximum contact region 664 may vary along different regions ofrim portion 127. In one embodiment, containers with diameters that are larger thanthird container diameter 610 may not properly contact the container and hinder the formation of a substantially airtight seal. Thus, in some embodiments, only containers with diameters that make contact withrim portion 127 in the range betweenminimum contact region 690 andmaximum contact region 664 may be utilized withfirst cover 100. It should also be understood thatfirst cover 100 may be installed on a variety and range of bowl sizes, as will be described further with respect toFIGS. 7-12 . - It should be understood that in different embodiments, the portions of
annular flange 300 that contact and form a seal with the containers may be disposed along different areas of a container. For example,second container 650 may include a seal withfirst cover 100 that is spaced further downward from the mouth ofsecond container 650 than another seal that is formed betweenthird container 600 andfirst cover 100. - With reference to
FIGS. 7-9 , to usefirst cover 100 on afourth container 700, a user may pressfirst cover 100 in a downward direction 602 (e.g., towardscontainer 700 whencontainer 700 is placed on a surface) to contact arim 706 offourth container 700.Fourth container 700 has an opening with asecond container diameter 710 that provides access to an inner section (not shown) offourth container 700. InFIG. 7 ,first cover 100 is shown abovefourth container 700 prior to contact between the two components.Opening 104 hasfirst diameter 450, and first cover hasmaximum diameter 604. As shown,second container diameter 710 is larger than first container diameter 550 (seeFIG. 5 ). However, in other embodiments,second container diameter 710 may be smaller thanfirst container diameter 550. - In
FIG. 8 ,first cover 100 is in an intermediate state where opening 104 may be enlarged greater thanfirst diameter 450. In other words, asfourth container 700 begins to enterchamber 102, andfirst cover 100 begins to make contact withfourth container 700, in some embodiments,rim portion 127 may touchrim 706 and curve, bend, flex, or otherwise deform upward. - In
FIG. 8 , asecond diameter 850 is associated with the distance betweenfirst tip 462 andsecond tip 464 ofrim portion 127.Second diameter 850 is greater thanfirst diameter 450. InFIG. 8 , it can be seen thatfirst flange portion 410 andsecond flange portion 420 ofrim portion 127 may slide or move along a portion of asidewall 820 offourth container 700. In other words, various areas ofrim portion 127 can deform to accommodate the entry offourth container 700, and one side of rim portion 127 (for example,second side 472 shown inFIG. 4 ) may press againstsidewall 820 offourth container 700. - As a user proceeds to install
first cover 100 onfourth container 700, as shown inFIG. 9 , an exposed surface associated with arim 902 offourth container 700 contacts rimportion 127 and forms afirst seal 904 withfirst cover 100 in some embodiments. Thus, in some embodiments, oncefourth container 700 has been fully engaged withfirst cover 100,first flange portion 410 andsecond flange portion 420 ofrim portion 127 may be bent in order to substantially press or compress an outer portion offourth container 700. Referring toFIGS. 7-9 , some or all ofrim portion 127 may bend or deform to varying degrees as a container engages with the chamber offirst cover 100. -
First seal 904 can provide a substantially airtight seal or otherwise limit air circulation to the inner portion (not shown) offourth container 700 and act as a barrier to help extend the period of freshness of any food within by limiting exposure to air, loss of moisture or loss of the natural preservation properties of the food. To facilitate the formation offirst seal 904,first cover 100 may be in a stretched, flexed, or deformed state, where the diameter ofopening 104 expands to athird diameter 900. It should also be understood thatchamber 102 offirst cover 100 may be in fluid communication with an inner chamber (not shown) offourth container 700 whenfirst cover 100 andfourth container 700 are joined together. - Thus, in different embodiments, the resilient nature of the material forming
first cover 100, as well as the adjustments possible to opening 104 from the undeformed state to the deformed state allowsfirst cover 100 to exert a compressive force on a portion of a container, and may securefirst cover 100 with the container. In one embodiment,first cover 100 may remain thereon until it is removed from the container. - As noted above,
first cover 100 has minimum diameter of opening 104 of first diameter 450 (seeFIG. 4 ). In different embodiments, opening 104 allowsfirst cover 100 to accommodate containers having a range of differing sizes, fromfirst diameter 450 to sizes larger thanfirst diameter 450. In addition to a range of sizes,first cover 100 may also be used on containers with uneven, curves or otherwise irregular rims in some embodiments. For example, as shown inFIGS. 10-11 ,first cover 100 may be used on afifth container 1000 with anornamental rim 1002. - Similar to the process described above with regard to
FIGS. 4-9 , with regard tofifth container 1000, a user may pressfirst cover 100 in a downward direction 602 (e.g., a direction towards fifth container 1000) to contactornamental rim 1002. InFIG. 10 ,fifth container 1000 has an opening with afifth container diameter 1010 that provides access to an inner area (not shown) offifth container 1000. As depicted herein,fifth container diameter 1010 is smaller than second container diameter 710 (shown inFIGS. 7-9 ). However, in other embodiments,fifth container diameter 1010 may be larger thansecond container diameter 710. Furthermore,fifth container 1000 includesornamental rim 1002 that forms an undulating edge along the opening offifth container 1000. Thus, in some embodiments,first cover 100 may be used with containers that have decorative, hand-made, or non-uniform edges along the rim. - In
FIG. 10 ,first cover 100 is shown abovefifth container 1000 prior to contact between the two components.Opening 104 hasfirst diameter 450, and first cover has amaximum diameter 604. InFIG. 11 ,first cover 100 has been installed onfifth container 1000. Opening 104 may be enlarged greater thanfirst diameter 450 asfirst cover 100 is installed. In other words, asfifth container 1000 begins to enteropening 104, andfirst cover 100 begins to make contact withfifth container 1000,first flange portion 410 andsecond flange portion 420 ofrim portion 127 offirst cover 100 may contactornamental rim 1002 and curve, bend, flex, or otherwise deform upward in some embodiments. - In
FIG. 11 , it can be seen thatfirst flange portion 410 andsecond flange portion 420 comprising portions ofrim portion 127 may slide or move along a portion of asidewall 1120 offifth container 1000. In other words,rim portion 127 can deform to accommodate the engagement offifth container 1000 withfirst cover 100. As a user installsfirst cover 100 onfifth container 1000, as shown inFIG. 11 ,sidewall 1120 associated withornamental rim 1002 offifth container 1000 forms asecond seal 1104 in some embodiments. Thus, in some embodiments, oncefifth container 1000 has been fully engaged withfirst cover 100,first flange portion 410 andsecond flange portion 420 may be bent to substantially press or compress an outer portion offifth container 1000. Referring toFIGS. 9-11 , some or all ofrim portion 127 may bend or deform to varying degrees as a container engages with the chamber offirst cover 100. - As noted above with respect to
first seal 904,second seal 1104 can form a substantially airtight seal, and limit air circulation to the inner portion (not shown) offifth container 1000 and act as a barrier to help extend the period of freshness of any food within by limiting exposure to air, loss of moisture or loss of the natural preservation properties of the food. Once the user releasesfirst cover 100,first cover 100 may be in a stretched, flexed, or deformed state where the diameter ofopening 104 has expanded to afourth diameter 1100. It should also be understood thatchamber 102 offirst cover 100 may be in fluid communication with an inner chamber (shown inFIG. 12 ) offifth container 1000. - Thus, the resilient nature of the material forming
first cover 100, as well as the adjustments possible to opening 104 from the undeformed state to the deformed state allowsfirst cover 100 to seal containers of varying sizes and rim types. As shown inFIGS. 7-11 ,first cover 100 may be used to coverfourth container 700 withsecond container diameter 710, as well asfifth container 1000 withfifth container diameter 1010. In some embodiments,second container diameter 710 may be larger thanfifth container diameter 1010. In other embodiments,second container diameter 710 may be smaller thanfifth container diameter 1010. Furthermore,first cover 100 may be utilized withfifth container 1000, wherefifth container 1000 may include anornamental rim 1002 or irregular design. - In different embodiments, a single reusable container cover may be used on a variety of bowl or container types, sizes, geometries, and materials. In
FIG. 12 , asecond cover 1200 is shown adjacent to a series ofcontainers 1280.Containers 1280 include a first container 1210, asecond container 1220, athird container 1230, afourth container 1240, afifth container 1250, and asixth container 1260. Each container may include a rim that borders the container's opening. - In different embodiments, each rim may be associated with varying diameters, such that a wide range of container shapes and sizes may be used. For example, in
FIG. 12 , first container 1210 has afirst rim 1212 with afirst diameter 1214,second container 1220 has arim 1222 with asecond diameter 1224,third container 1230 has arim 1232 with athird diameter 1234,fourth container 1240 has arim 1242 with afourth diameter 1244,fifth container 1250 has arim 1252 with afifth diameter 1254, andsixth container 1260 has arim 1262 with asixth diameter 1264. In some embodiments, the diameters ofcontainers 1280 may range from very small rims to large rim sizes, forming a variety of aperture sizes. Thus, one feature of the embodiments described herein is a single cover's application to multiple containers and container diameters. - For example,
second cover 1200 may be applied to several container diameters. In some embodiments,first diameter 1214 may be less thansecond diameter 1224,second diameter 1224 may be less thanthird diameter 1234,third diameter 1234 may be less thanfourth diameter 1244,fourth diameter 1244 may be less thanfifth diameter 1254, andfifth diameter 1254 may be less thansixth diameter 1264. In one embodiment, the diameter ofindividual containers 1280 that may be used with reusable covers may range from less than 20 mm to greater than 500 mm. It should be understood that greater than six covers and sizes or types may be used with a single reusable cover in different embodiments. - Thus, in the application and installation of
second cover 1200, there may bemultiple containers 1280 that are covered bysecond cover 1200. In one example,first diameter 1214 may be approximately 120 mm,second diameter 1224 may be approximately 125 mm,third diameter 1234 may be approximately 126 mm,fourth diameter 1244 may be approximately 130 mm,fifth diameter 1254 may be approximately 135 mm, andsixth diameter 1264 may be approximately 140 mm. It should be understood that the values listed herein are provided as examples, and a wide range of other diameter sizes may be utilized with the reusable covers described herein, including sizes of less than 120 mm, and greater than 140 mm. In other embodiments, for example, a relatively “larger”second cover 1200 may be used forcontainers 1280 ranging from 140 mm to 165 mm. In another embodiment, a relatively “smaller”second cover 1200 may be used forcontainers 1280 ranging from 100 mm to 125 mm. In other embodiments, there can be reusable covers of various sizes (e.g., extra-small, small, medium, large, extra-large, specialized, etc.) that can each be utilized on containers of multiple sizes. In one exemplary embodiment, reusable covers may include a range of sizes to permit easy use for a wide range of container diameters and types. Because the covers described herein may be in a variety of sizes and depths, they can be used with a variety of containers. - In addition, in some embodiments, the covers described herein may be nested within one another. An example of nesting that may be used herein is disclosed in Ivankovic, et al., U.S. Patent Publication Number 2014/023,887, filed Jul. 30, 2013 and titled “Reusable Food Covers,” which application is herein incorporated by reference. Embodiments of the present disclosure can make use of any of the components, mechanisms, structure, and methods disclosed in the Reusable Food Covers application.
- Furthermore, the covers of the present embodiments can be configured for a range of container types, including containers with significantly varied lip sizes and geometries. One example was given with respect to
FIG. 6 . A further example is depicted with respect tothird container 1230, which includes a mouth or container opening comprising a generally square shape. Thus, whilesecond cover 1200 includes a substantially round geometry, as a result of the high degree of stretchability, resilience, and elasticity of the flexible wall,second cover 1200 may accommodate containers with non-circular geometries as well. - The covers may also be applied to containers with a variety of lip types. For purposes of this description, a lip of a container may refer to any portion of the container that extends beyond the rim surrounding the opening or mouth of the container. The lip may vary in size, thickness, length, and/or geometry.
FIGS. 13-15 provide additional examples of the versatility of the reusable cover. InFIG. 13 ,third cover 1300 has been installed on afirst container 1302.Third cover 1300 has formed a seal with afirst sidewall surface 1308, so that amouth 1304 offirst container 1302 is covered or otherwise enclosed within the chamber formed bythird cover 1300 andfirst container 1302. However,first container 1302 further includes afirst lip 1306 that extends beyondmouth 1304, in a generally horizontal direction, forming a substantially flat ledge or overhang that enlarges the overall diameter offirst container 1302 farther beyondmouth 1304 offirst container 1302.Third cover 1300 fits overfirst container 1302 by first fitting overfirst lip 1306, and capturing the entire edge associated withfirst lip 1306 betweenfirst flange portion 410 andsecond flange portion 420 ofrim portion 127. Oncefirst lip 1306 passes through or slides alongrim portion 127, a seal may be formed by contact betweenrim portion 127 andfirst sidewall surface 1308 offirst container 1302. - Similarly, in
FIG. 14 ,third cover 1300 has been installed on asecond container 1402.Third cover 1300 has formed a seal with asecond sidewall surface 1408 so that amouth 1404 ofsecond container 1402 is covered, otherwise enclosed within the chamber formed bythird cover 1300 andsecond container 1402. In addition,second container 1402 includes asecond lip 1406 that extends outward frommouth 1404 in a horizontal direction, forming a substantially curled or rounded ledge that enlarges the overall diameter ofsecond container 1402 beyondsecond mouth 1404 ofsecond container 1402.Third cover 1300 fits oversecond container 1402 by first fitting oversecond lip 1406, and capturing the entire edge associated withsecond lip 1406 aroundsecond container 1402. After sliding pastsecond lip 1406, a seal may be formed through the contact betweenrim portion 127 andsecond sidewall surface 1408 ofsecond container 1402. - In another embodiment,
third cover 1300 may be used with containers of a different lip type. For example, inFIG. 15 ,third cover 1300 is installed on athird container 1502.Third cover 1300 has formed a seal with athird sidewall surface 1508 so that amouth 1504 ofthird container 1502 is covered or otherwise enclosed within the chamber formed bythird cover 1300 andthird container 1502. In addition,third container 1502 includes athird lip 1506 that extends outward in a horizontal direction, forming a curved ledge that enlarges the overall diameter ofthird container 1502 beyondmouth 1504 ofthird container 1502.Third cover 1300 fits overthird container 1502 by sliding or passing overthird lip 1506, and enclosing the entire edge associated withthird lip 1506 withinthird container 1502. Oncerim portion 127 slides pastthird lip 1506, a seal may be formed through the contact betweenrim portion 127 andthird sidewall surface 1508 ofthird container 1502. - The embodiments of reusable covers described herein may also include provisions for stacking containers utilizing the reusable covers. For example, the lids provided on containers in the form of the reusable covers can have a rigid portion (for example, base 110) that allows other containers to be placed upon them in some embodiments. In
FIG. 16 , stackedcontainers 1600 are depicted.Stacked containers 1600 include afourth container 1642, afifth container 1652, and asixth container 1662. Furthermore, afourth cover 1640 has been installed onfourth container 1642, afifth cover 1650 has been installed onfifth container 1652, and asixth cover 1660 has been installed onsixth container 1662. - As described earlier with respect to
FIG. 3 , each base 110 may include substantially flatcentral portion 112. As a result of the material(s) and structural features ofbase 110,base 110 may provide a firm, stable surface for the placement of other objects, including additional containers. As shown inFIG. 16 ,fourth container 1642 has afirst bottom surface 1620. Firstbottom surface 1620 has been placed such that it is in contact with afirst base 1622 offifth cover 1650 installed onfifth container 1652. In other words,first base 1622 can provide a resilient surface for supportingfourth container 1642 in some embodiments, and/or the weight offourth container 1642 and its contents, as well as the weight offourth cover 1640. In addition, in one embodiment,first base 1622 can act as a supportive, generally rigid surface forfourth container 1642. This can allow a user to easily store different items and/or various containers that may be covered by the reusable covers, and then readily stack the containers atop each other for convenient storage. In some embodiments, this can allow for a more efficient use of space. For example, refrigerators, pantries, cabinets, or other areas may have a limited capacity. Stacking as depicted herein may allow a user to take greater advantage of the storage space available. - Similarly,
fifth container 1652 may include asecond bottom surface 1624, which may be in contact with asecond base 1626 ofsixth cover 1660 installed onsixth container 1662. As discussed with respect tofifth cover 1650,sixth cover 1660 may also provide a resilient surface for supportingsecond bottom surface 1624 offifth container 1652 in some embodiments. It should be understood thatfourth cover 1640 may also be used to provide a stacking surface for containers in other embodiments. - While the upper surface of each reusable cover associated with
central portion 112 is generally flat, in some embodiments, the reusable covers may include a ridge, as discussed with respect toFIGS. 4 and 5 .Fourth cover 1640,fifth cover 1650, andsixth cover 1660 are shown to each include ridges. As an example,sixth cover 1660 is seen to include 466.Ridge 466 may promote stability during stacking by providing a barrier against slippage or other movement of the stacked containers. In other words, the raised border ofridge 466 along one or more of the reusable covers can provide a kind of guardrail in some embodiments, helping to improve or maintain the balance, alignment, and/or placement ofstacked containers 1600. - It can also be noted that in the embodiment of
FIG. 16 , the overall size offourth container 1642 is less than the overall size offifth container 1652, and the overall size offifth container 1652 is less than the overall size ofsixth container 1662. However, it should be understood that in other embodiments, the sizes of containers may differ such that the relationship betweenstacked containers 1600 varies. In other words, in some embodiments,fourth container 1642 may be substantially similar in size tofifth container 1652 and/orsixth container 1662. Thus, stackedcontainers 1600 need not be stacked such that the largest container is at the bottom and the smallest container is on top. In other embodiments, a smaller container may be disposed at the bottom, and a relatively larger container may be stacked atop the smaller container. - Furthermore, referring to
FIG. 16 ,fourth cover 1640,fifth cover 1650, andsixth cover 1660 may be formed of a material of a single color in one embodiment, or each size cover may be formed of a different color material so that the sizes are color coded in another embodiment. This may allow users to quickly identify the different sizes of each cover. - It should be understood that a reusable cover of the embodiments described herein can be easily removed when needed and can be readily replaced again on the same container or a new container. In some embodiments, the resilience and elasticity of
flexible wall 120 can provide a means of easy removal of the cover from a container. The ease of use of the covers enables users to store food or such items in a fresh state multiple times without experiencing the quick and significant loss of freshness, which would happen if left unsealed and exposed to open air. In addition, items stored in a container with the reusable covers are secured and may remain within the container in the event of sudden movement, mishandling, or even if the container were to be dropped. - Furthermore, in some embodiments, a cover may include additional provisions for releasing the cover from a container. For example, in
FIGS. 17 and 18 , arelease tab 1750 along the perimeter ofseventh cover 1700 is shown. As illustrated,release tab 1750 is generally oval, and disposed alongflexible wall 120 ofseventh cover 1700, such thatrelease tab 1750 is folded over and extends such that it is adjacent tocentral portion 112 ofbase 110. In one embodiment,flexible wall 120 can be molded to includerelease tab 1750. Thus,release tab 1750 may comprise substantially similar material toflexible wall 120. In some embodiments,release tab 1750 may comprise a greater thickness than the remainder offlexible wall 120. - In the embodiment of
FIGS. 17 and 18 ,release tab 1750 includes anupper end 1754 extending upward fromflexible wall 120, and alower end 1752 extending downward fromflexible wall 120.Upper end 1754 may be joined to a portion ofbase 110 and fold or bend to partially extend along the top surface ofseventh cover 1700 in some embodiments. - In other embodiments,
release tab 1750 may be any other shape, including round, elliptical, square, hexagonal, and other regular or irregular shapes. Thus, it should be understood that the geometry, proportions, size, location ofrelease tab 1750 may vary. For example,release tab 1750 may be larger than depicted in some embodiments. In another embodiment,release tab 1750 may be round. In one embodiment,release tab 1750 may be disposed within at least a portion ofbase 110 and/or within the center ofbase 110. Thus, in some embodiments,release tab 1750 may be completely surrounded bycentral portion 112. - As shown in the cross section of
FIG. 18 , in some embodiments,release tab 1750 may be pulled off the bottom edge of aseventh container 1820. In other words,release tab 1750 may be used as a lever to help removeseventh cover 1700. In one embodiment,release tab 1750 may be readily depressed by graspinglower end 1752 ofrelease tab 1750 with (for example) the forefinger of a hand and pressing a button portion alongupper end 1754 ofrelease tab 1750 with the a thumb 1800 (or other vector) and generally applying a pullingforce 1810. In other embodiments, a prying action alongrelease tab 1750 can help pullseventh cover 1700 offseventh container 1820. In one embodiment, asrelease tab 1750 is depressed,seventh cover 1700 has sufficient rigidity to pivot as a unit and disengage with arim 1830 ofseventh container 1820. In another embodiment, at least a portion ofseventh cover 1700 may be lifted by depression ofrelease tab 1750. For example, depression ofupper end 1754 may weaken the seal that exists betweenseventh container 1820 andseventh cover 1700. In one embodiment, the remainder ofseventh cover 1700 may be more readily disengaged from the rim ofseventh container 1820 once an initial portion has been separated from the depression ofrelease tab 1750. - In another embodiment, not shown, a button portion may be disposed within
upper end 1754 ofrelease tab 1750, andupper end 1754 can be used to press and/or pushseventh container 1820 away while pulling onrelease tab 1750. In other embodiments,upper end 1754 may be used to push air out ofseventh container 1820 in order to help releaseseventh cover 1700. - Referring to
FIGS. 19-23 , another series of embodiments of a reusable cover are depicted. InFIG. 19 , covers 1900 are illustrated, including aneighth cover 1950, aninth cover 1960, and atenth cover 1970.Covers 1900 each include a base and a flexible wall. For example,eighth cover 1950 includes abase 1910 and aflexible wall 1920.Base 1910 may be generally circular in shape in some embodiments.Flexible wall 1920 may extend outwardly from base 1910 to define achamber 1902 and anopening 1904.Flexible wall 1920 also includes includes anannular flange 1930 in some embodiments.Flexible wall 1920 may therefore also be substantially rounded in some embodiments. InFIG. 19 ,eighth cover 1950,ninth cover 1960, andtenth cover 1970 are shown in an undeformed or initial state (i.e., where covers 1900 have not been installed on a container).Covers 1900 may vary in size, and in some embodiments, may be nested within one another. An example of such nesting that may be used herein is disclosed in the Reusable Food Covers application. Embodiments of the present disclosure can make use of any of the components, mechanisms, structure, and methods disclosed in the Reusable Food Covers application. - For purposes of clarity, the following discussion focuses on
base 1910 andflexible wall 1920 ofeighth cover 1950, but it may be appreciated that each of the covers incovers 1900 may include a base and a flexible wall having similar characteristics. - In contrast to the embodiments discussed with reference to
FIGS. 1-18 , covers 1900 may include a relativelyflat base 1910 that joinsflexible wall 1920 along the top (in the horizontal plane) surface. In some embodiments,base 1910 is substantially round or circular. This can be seen best inFIGS. 20-22 , where a cross-section of aneleventh cover 2000 is depicted as it is installed on an schematic illustration of aneighth container 2050. InFIG. 20 ,base 1910 is shown as it is joined toflexible wall 1920 near aperiphery 2061 bordering the circumference ofbase 1910. -
Base 1910 may be joined to anupper ring portion 2025 offlexible wall 1920 in various ways. In some embodiments, the structural features ofbase 1910 andflexible wall 1920 may provide a means for joining or helping to attach base 1910 toflexible wall 1920 to formeleventh cover 2000. For example, inFIGS. 20-22 ,upper ring portion 2025 may include an opening, slot, or other mechanism for attaching or joining tobase 1910. In one embodiment, a similar structural mechanism as described with respect to covers inFIGS. 4 and 5 (including, for example,first wall 430 and second wall 440) may be included inupper ring portion 2025. In some embodiments,flexible wall 1920 andbase 1910 can be over molded with generous purchase for surface contact adhesion. In other embodiments, a weld, an adhesive, or another bonding agent may be also be used to join the components together. In cases where a welding process is used, the weld could be an ultrasonic weld or any other type of weld. - As discussed earlier with respect to the embodiments of
FIGS. 1-18 , during use with various containers, covers 1900 ofFIG. 19 may provide a seal between a container and a cover.FIG. 20 illustrates an embodiment ofeleventh cover 2000 in an initial, or undeformed configuration,FIG. 21 illustrateseleventh cover 2000 as it is being applied toeighth container 2050, andFIG. 22 illustrates an embodiment ofeleventh cover 2000 in its installed configuration. - In different embodiments,
flexible wall 1920 may include alower ring portion 2026 that extends in a generally vertical direction, which may help define the height ofchamber 1902.Lower ring portion 2026 may be joined to arim portion 2027, which extends toward the center ofeleventh cover 2000 in a generally horizontal direction.Lower ring portion 2026 may be curved in some embodiments. As shown inFIGS. 20-22 ,lower ring portion 2026 includes a curved region that extends betweenupper ring portion 2025 andrim portion 2027, providing a geometry that may better accommodate a container and/or improve the fit with a container. In some embodiments,lower ring portion 2026 may be approximately perpendicular torim portion 2027 in the initial state. - In
FIGS. 20-22 ,rim portion 2027 includesannular flange 1930. In the cross sectional view ofFIGS. 20-22 ,annular flange 1930 includes two portions, identified herein asfirst flange portion 2010 and asecond flange portion 2020. Althoughfirst flange portion 2010 andsecond flange portion 2020 are individually labeled inFIGS. 20-22 , it should be understood that they comprise two portions ofrim portion 2027. In other words, in one embodiment,rim portion 2027 comprises continuousannular flange 1930, andfirst flange portion 2010 andsecond flange portion 2020 simply identify two areas along the continuousannular flange 1930. Thus,first flange portion 2010 and/orsecond flange portion 2020 should not be understood to refer to two distinct parts or components. - As discussed with reference to the embodiments of
FIGS. 1-18 ,rim portion 2027 may have varying widths in different embodiments. In one embodiment, the width ofrim portion 2027 may help define a diameter ofopening 1904. Thus, opening 1904 may have afirst opening diameter 2060. It should be understood that the diameter ofopening 1904 may expand asfirst flange portion 2010 and/orsecond flange portion 2020 taper, bend and/or curl upward. In other words,first opening diameter 2060 may change significantly aseleventh cover 2000 is attached or joined to a container or other component. For example, in use, containers (such as a bowl) may have a diameter greater thanfirst diameter 2060. As depicted inFIGS. 20-21 , aseleventh cover 2000 is installed oneighth container 2050, it can be seen that acontainer diameter 2090 is greater thanfirst opening diameter 2060. As a result, wheneighth container 2050 enterschamber 1902,first flange portion 2010 andsecond flange portion 2020 move or bend upwardly to compress asidewall 2030, applyingrim portion 2027 aroundeighth container 2050. Thus, the yielding flexibility ofrim portion 2027 permits the engagement of a container with a diameter greater thanfirst opening diameter 2060. In other words, as shown inFIG. 22 , upon installation ofeleventh cover 2000 uponeighth container 2050, the distance betweenfirst flange portion 2010 andsecond flange portion 2020 may increase to asecond opening diameter 2260 that is substantially similar to container diameter 2090 (shown inFIG. 20 ). It should be understood that the mechanism of installing and/or forming a seal with respect to the embodiments ofFIGS. 19-22 may be substantially similar to the mechanisms described in the embodiments ofFIGS. 1-18 in some embodiments. Thus, in different embodiments, covers 1900 (as shown inFIG. 19 ) may each allow accommodation and sealing of containers having a range of differing sizes. - The covers described herein may additionally include provisions for improving grip of the cover, as well as stability, particularly during stacking of containers that utilize the reusable covers disclosed herein. In
FIG. 23 , atwelfth cover 2310 installed on aninth container 2315, and athirteenth cover 2320 installed on atenth container 2325 are illustrated.Ninth container 2315 is stacked onbase 1910 ofthirteenth cover 2320. Alongperiphery 2061 ofbase 1910, wherebase 1910 is joined toflexible wall 1920, an uneven surface has formed, due to the change in height betweenbase 1910 andupper ring portion 2025. Thus, in some embodiments, astep 2366 may be disposed along the border ofbase 1910 ofthirteenth cover 2320.Step 2366 may exist along the entire border ofbase 1910 ofthirteenth cover 2320, or along a portion ofbase 1910.Step 2366 can be an undulation or bump or other formation that provides additional grip to each cover for easier handling. In addition, similar toridge 466 of the embodiments inFIGS. 1-18 ,step 2366 may allow for greater stability during stacking of containers. - For example, the lids provided on containers in the form of the reusable covers can have a rigid portion (for example, base 1910) that allows other containers to be placed upon them in some embodiments. In
FIG. 23 , twostacked containers 2300 are depicted. As a result of the material(s) and/or structural features ofbase 1910,base 1910 may provide a firm, stable surface for the placement of other objects, including additional containers. In addition,step 2366 can decrease the likelihood ofninth container 2315 slipping off the surface ofbase 1910 ofthirteenth cover 2320. This can allow a user to more readily stack the containers atop each other for convenient storage. In some embodiments, stacking can allow for a more efficient use of space. For example, refrigerators, pantries, cabinets, or other areas may have a limited capacity. Stacking as depicted herein may allow a user to take greater advantage of the storage space available. - It should be understood that the cover of
FIGS. 19-23 can also be easily removed by pulling the container away from the cover. Thus, the cover may be removed from a container and replaced multiple times. - The materials comprising the reusable covers described herein may vary in different embodiments. The base may be transparent, semi-transparent or opaque. In a preferred embodiment, as depicted in
FIGS. 1-23 , the base may be substantially transparent. In one embodiment, the base (for example,base 110 ofFIGS. 1-18 , orbase 1910 ofFIGS. 19-23 ) or components comprising the base can be associated with a transparent material. In some embodiments, the material comprising the base is transparent, resilient, and washable. Examples of different materials that could be used for one or more portions of the base include, but are not limited to: glass, plastics, polymer sheets, or combinations thereof. In some embodiments, the base may be made from a suitable polymeric material, preferably a polymer that can meet a certain transparency and low haze level (to allow for proper viewing of the contents beneath the food cover) and rigidity, such as polyolefins and polycarbonates. Some examples of suitable plastic materials include a polyvinylchloride, cellulose acetate, nylon, polycarbonate, polystyrene, polypropylene, polyethylene, polyester, acrylonitrile copolymers, coextruded plastics, etc. These materials may be coated with saran or other coating if desired. Copolymers of these various plastics may be used in order to obtain desired properties. In embodiments where polymer sheets are used, the polymer sheets may be extruded, rolled, or otherwise formed from a polymer material to exhibit a generally flat aspect. Two-dimensional materials may also encompass laminated or otherwise layered materials that include two or more layers of textiles, polymer sheets, or combinations of textiles and polymer sheets In addition to textiles and polymer sheets, other two-dimensional materials may be utilized for the transparent portions. - In addition, flexible wall (such as
flexible wall 120 ofFIGS. 1-18 orflexible wall 1920 ofFIGS. 19-23 ) may be integrally formed of a single, unitary material using process such as, for example, molding. The flexible wall or portions thereof may be formed of a flexible material. In some cases, a material that includes silicone or a high grade food safe silicone may be used. In some cases, a material may include rubber. In some cases, the flexible portions may be formed of a material that can include thermoplastic elastomers (TPE). In some cases, the flexible wall can be made of a material that includes thermoplastic rubbers. In some cases a combination of two or more of the materials disclosed above. It should be understood that the base may comprise a material that includes a greater rigidity than that of the flexible wall in some embodiments. - It should also be noted that in some embodiments, the materials comprising the covers described herein may be dishwasher-safe, microwaveable, food-safe, and/or resistant to bacteria or other food-borne germs. Thus, the reusable cover can be used for the storage of foods and materials at room temperature, in a refrigerator or in a freezer. Furthermore, in other embodiments, the reusable covers may include materials that provide additional insulation to a container. In one embodiment, the covers may be water resistant or water proof, such that a container utilizing a reusable container is also spill-proof or spill-resistant with the use of liquids. As noted above, the reusable cover can be fabricated at least in part of a transparent material to permit observation of the food product within the container without removal of the reusable cover. In addition, in some embodiments, covers may be turned inside-out for easier cleaning or use.
- As discussed earlier with respect to
FIGS. 4 and 5 , in some embodiments,annular flange 300 may deform in an axially, allowing opening 104 to move upward in an axial direction alongcentral axis 439. For example, as seen inFIGS. 4 and 5 , opening 104 is disposed nearer to base 110 along the direction ofcentral axis 439 when in the deformed state ofFIG. 5 than when in the initial state ofFIG. 4 . Furthermore, thediameter 104 may also vary when in the deformed state. These features are discussed in greater detail with respect toFIGS. 24-27 . - In
FIG. 24 , a cut-away view of a portion offirst cover 100 is shown as it is deformed and applied on aneleventh container 2410, and inFIG. 25 , a top-down view of the same portion offirst cover 100 in the initial state is shown.Eleventh container 2410 has asecond diameter 2400. In one embodiment, asfirst cover 100 is installed oneleventh container 2410 andannular flange 300 makes contact with asidewall 2420 ofeleventh container 2410,annular flange 300 may deform upward. In other words, radiallyouter limit 668 associated with the radially outermost edge ofannular flange 300 can move upward along the direction ofcentral axis 439. Thus, in some embodiments, opening 104 (shown inFIG. 25 ) defined by radiallyouter limit 668 may move or translate axially upward alongcentral axis 439 as it slides or otherwise moves alongsidewall 2420 ofeleventh container 2410. - As shown in
FIG. 24 ,minimum contact region 690 offirst cover 100 makes contact witheleventh container 2410 and can form a seal.Minimum contact region 690 ofannular flange 300 can also be seen inFIG. 25 , where a top-down view of the portion offirst cover 100 is provided. During the process of insertingfirst cover 100 oneleventh container 2410, radiallyouter limit 668 ofannular flange 300 moves from its initial (undeformed) axial position over a first axial distance 2450 (shown inFIG. 24 ) along the direction ofcentral axis 439. Firstaxial distance 2450 may be measured from ahorizontal axis 2440, wherehorizontal axis 2440 corresponds to the axial position of radiallyouter limit 668 in the initial state. Thus, opening 104 (shown inFIG. 25 ) ofannular flange 300 can be understood to move axially upward whenfirst cover 100 is installed on a container. - In
FIG. 26 , a cut-away view of a portion offirst cover 100 is shown as it is deformed and applied on atwelfth container 2610, and inFIG. 27 , a top-down view of the same portion offirst cover 100 in the initial state is shown.Twelfth container 2610 has athird diameter 2600. Referring toFIGS. 24 and 26 , it can be seen thattwelfth container 2610 has a larger diameter thaneleventh container 2410, such thatsecond diameter 2400 is less thanthird diameter 2600. In one embodiment, asfirst cover 100 is installed ontwelfth container 2610 andannular flange 300 makes contact with asidewall 2620 oftwelfth container 2610,annular flange 300 may deform further upward. In other words, radiallyouter limit 668 associated with the radially outermost edge ofannular flange 300 can move further upward along the direction ofcentral axis 439 relative to the embodiment ofFIG. 24 . In other words, in some embodiments, as radiallyouter limit 668 slides or otherwise moves alongsidewall 2620 oftwelfth container 2610, opening 104 (shown inFIG. 27 ) ofannular flange 300 may move or translate axially upward along central axis 439 a greater distance than that shown inFIG. 24 . - In
FIG. 26 ,maximum contact region 664 offirst cover 100 makes contact withtwelfth container 2610 and can form a seal.Maximum contact region 664 ofannular flange 300 can also be seen inFIG. 25 , where a top-down view of the portion offirst cover 100 is provided. During the process of inserting or installingfirst cover 100 ontwelfth container 2610, radiallyouter limit 668 ofannular flange 300 moves from its initial (undeformed) axial position over a secondaxial distance 2650 along the direction ofcentral axis 439. Secondaxial distance 2650 may be measured fromhorizontal axis 2440, wherehorizontal axis 2440 corresponds to the initial axial position of radiallyouter limit 668. Secondaxial distance 2650 is greater than first axial distance 2450 (seeFIG. 24 ). It should be understood that asfirst cover 100 is installed on a larger container diameter, opening 104 may also move further axially upward. Thus, while radiallyouter limit 668 ofannular flange 300 has translated along firstaxial distance 2450 ofeleventh container 2410 inFIG. 24 , it translates a greater secondaxial distance 2650 in order to accommodate the largertwelfth container 2610 inFIG. 26 . The examples ofFIGS. 24-27 depict two containers that can form a seal withfirst cover 100 through application of eitherminimum contact region 690 ormaximum contact region 668. However, as illustrated inFIG. 28 , it should be understood thatfirst cover 100 may also accommodate a number of container diameters. For example,first cover 100 may be installed on containers in arange 2800, extending between the size ofeleventh container 2410 and the size oftwelfth container 2610. - In addition, as described above with reference to
FIGS. 4-5 , it can be seen that the diameter associated with opening 104 ofannular flange 300 may increase whenfirst cover 100 is installed on different containers. For example, in some embodiments, referring toFIGS. 24 and 25 , upon installation offirst cover 100 oneleventh container 2410, opening 104 may increase in diameter fromfirst diameter 450 to a larger diameter that may be substantially similar tosecond diameter 2400 ofeleventh container 2410. A similar relationship may be observed with respect toFIGS. 26 and 27 . Afterfirst cover 100 has been installed ontwelfth container 2610, opening 104 may increase in diameter fromfirst diameter 450 to a larger diameter that may be substantially similar tothird diameter 2600 in some embodiments. Thus, it can be seen that opening 104 may grow in size fromfirst diameter 450 tosecond diameter 2400, and then further expand tothird diameter 2600. The expansion ofopening 104 may depend on the dimensions of the container. - Furthermore, it should be understood that the covers described herein may be substantially elastic and flexible. As used in the description, elastic refers to the ability of a material to substantially resume its normal (initial) shape spontaneously after deformation, contraction, dilation, or distortion. Thus, in different embodiments,
first cover 100 may substantially return to its initial state once it is removed (uninstalled) from a container. For example, inFIG. 29 , a sequence of views offirst cover 100 are depicted. In abottommost embodiment 2920,first cover 100 is mounted or installed on acontainer 2950, such that arim portion 2960 is deformed along aregion 2930 ofannular flange 300. In acentral embodiment 2970 ofFIG. 29 ,first cover 100 has been separated fromcontainer 2950, andannular flange 300 is partially deformed, and in the process of springing or moving back toward the horizontal plane. Finally, as shown in anuppermost embodiment 2980,first cover 100 has resumed a state substantially similar to the initial state, as described above. Thus,first cover 100 may be installed and uninstalled repeatedly on one or more containers, and retain its ability to form a seal. - While various embodiments have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the embodiments. Although many possible combinations of features are shown in the accompanying figures and discussed in this detailed description, many other combinations of the disclosed features are possible. Any feature of any embodiment may be used in combination with or substituted for any other feature or element in any other embodiment unless specifically restricted. Therefore, it will be understood that any of the features shown and/or discussed in the present disclosure may be implemented together in any suitable combination. Accordingly, the embodiments are not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
