FIELD OF THE INVENTION
The present invention generally relates to devices and methods for transporting items, and it more specifically relates to insulated carriers for use in delivering temperature-controlled items such as perishable food.
BACKGROUND
Multipurpose containers and coverings are commonly used for packing, storing, transporting, and insulating items, particularly those such as food, beverages, and other items that need to be kept warm or cool for a significant period of time during storage or transport. Existing products suffer from a number of drawbacks. First, such products generally are large and bulky, featuring rigid walls. These types of containers are difficult to store or transport while not in use, and they may be difficult to carry or move while loaded with items. Second, existing products often rely on cooling media that are not suitable for use for longer periods of time while transporting or storing items, particularly within the delivery context. By way of example, larger picnic-style coolers with rigid walls are generally filled with ice, which melts and can make the contents of coolers wet. This renders the coolers unsuitable for use with certain types of items, such as food. The ice is also bulky and takes up a significant amount of space in the cooler in order to provide adequate cooling. Alternatively, some containers place a cooling media (such as gel packs) in the lining of the container walls. However, such existing containers are typically bulky and take up a relatively large amount of space in a freezer when cooling. Other containers are known which contain gel material in the walls for cooling or heating purposes, but these are also bulky and difficult to fold into a compact condition, and they may be difficult to heat. The problems caused by these containers are compounded when the containers are scaled to a larger size. For example, in the context of delivery, where there is a need for containers of various sizes and an efficient means of storage and transport, containers that are large enough to accommodate larger loads are particularly bulky and difficult to store and transport.
SUMMARY
A need exists for improved containers for storing and transporting items, particularly those that must be maintained in a temperature-controlled environment. The devices and related methods described in the present disclosure address the drawbacks of existing designs.
Embodiments disclosed in the present application provide such improved containers that may be collapsed so as to allow for the efficient storage and transport of the container while empty. In particular, the disclosed embodiments provide containers that may be stored in a freezer or other temperature-controlled environment without taking up significant space.
In an embodiment, a collapsible container comprises: a base panel with one or more horizontal creases; a front wall extending from the base panel; a rear wall extending from the base panel opposite the front wall; a pair of opposing side walls extending from the base panel between the front wall and the rear wall, each of the pair of opposing side walls comprising a vertical crease that is orthogonal to the base panel; wherein the base panel, the front wall, the rear wall, and the pair of opposite side walls define a cavity therebetween; wherein the container is configured to fold into a collapsed configuration by folding the base panel and each of the side walls into the cavity along the one or more horizontal creases and the pair of vertical creases; and wherein the base panel, the front wall, the rear wall, and the pair of opposing side walls each comprise an interior layer proximate the cavity, an exterior layer, and a layer of insulation therebetween.
An embodiment provides a method of collapsing a container comprising a base panel with one or more horizontal creases and a peripheral wall comprising a pair of opposing side walls; each with one or more vertical creases, the peripheral wall extending from the base panel to form a cavity, the method comprising the steps of: folding the base panel into the cavity along the one or more horizontal creases; and folding the pair of opposing side walls into the cavity along the one or more vertical creases.

DETAILED DESCRIPTION
For the purposes of promoting and understanding the principles disclosed herein, reference is now made to the preferred embodiments illustrated in the drawings, and specific language is used to describe the same. It is nevertheless understood that no limitation of the scope of the invention is hereby intended. Such alterations and further modifications in the illustrated devices and such further applications of the principles disclosed and illustrated herein are contemplated as would normally occur to one of skill in the art to which this disclosure relates.
Insulated Delivery Container
FIGS. 1 through 10 illustrate a first embodiment of an insulated delivery container 100. In the depicted embodiment, the container 100 generally comprises a rectangular structure having a base panel 102, a front wall 104, a rear wall 106, opposite side walls 108, 110, and a lid 112, which together define a cavity which receives items to be transported or stored in the container 100 (such as, but not limited to, articles of food, beverages, and the like). In other embodiments (not shown), the container 100 may take other shapes. By way of example and not of limitation, in other embodiments, the container 100 may have a greater or lesser number of walls (e.g., being cylindrical in shape and having only a single side wall, or being polyhedral and having additional walls).
As shown, the lid 112 is attached to the rear wall 106 such that the lid 112 may be folded away from the side walls 108, 110 and the front wall 104 to permit access to the cavity within the container. In alternative embodiments, the lid 112 may be attached to a different one of the walls 104, 106, 108, 110 or may be removably attached to multiple of the walls 104, 106, 108, 110.
As shown in FIGS. 48 and 49, in an alternative embodiment, the lid 112 comprises a thicker, inner portion 4801 that extends from the underside of the lid 112 and a thinner, outer portion 4803 such that the thicker, inner portion 4801 extends into the cavity of the container 100 when the lid 112 is in the closed position and the thinner, outer portion 4803 rests proximate to the walls 104, 106, 108, 110 such that the lid 112 does not fall into the cavity of the container 100.
As shown in FIG. 37, in an alternative embodiment, the lid 112 is attached to one of the side walls 110, removably attached to the front wall 104 and the rear wall 106 by attachment mechanisms such as zippers or the like, and removably attached to the opposing side wall 108 by a fastener such as a hook-and-loop fastener or the like so as to allow the lid to be folded away from the opposing side wall 108, the front wall 104 and the rear wall 106 to permit access to the cavity within the container 100.
In an embodiment, a flap 122 extends from the lid 112 towards the base panel 102 such that the flap 122 overlaps the portion of the side walls 108, 110 and the front wall 104 proximate the lid 112. In an embodiment, as shown in FIG. 48, a fastener 4802a, 4802b such as a hook-and-loop fastener, a pair of clips, or the like may be used to removably attach the lid 112 to one or more of the walls 104, 108, 110 so as to prevent the lid 112 from being inadvertently lifted while the container 100 is in use (e.g., while the container 100 is being used to store or transport items).
As shown in FIGS. 6 through 9, in embodiments the container 100 is collapsible to permit the container 100 to be easily transported or stored while empty. As shown, vertical creases 124a, 124b extend along the side walls 108, 110 from proximate the base panel 102 to proximate the front wall 104 to facilitate folding of the side walls 108, 110 when the container 100 is collapsed. The base panel 102 also includes one or more creases 126 to facilitate folding the base panel 102. To collapse the container 100, the base panel 102 folds into the container 100 along the creases 126 while the side walls 108, 110 fold into the container 100 along creases 124a, 124b such that the front wall 104 moves towards the rear wall 106. The container 100 is secured in the collapsed configuration by using clips 120a, 120b, 118a, 118b. A pair of clips 120a, 120b are attached to the lid 112 via straps 121a, 121b over the side walls 108, 110, with complementary clips 118a, 118b connected to the front wall 104 by straps 119a, 119b. Once the container 100 is collapsed, clip 120a attaches to complementary clip 118a, and clip 120b attaches to complementary clip 118b. In an embodiment, the distance between the complementary clips 118a, 118b can be adjusted by sliding the clips 118a, 118b along the straps 119a, 119b, allowing for the container 100 to be secured in a collapsed state while varying the distance between the front wall 104 and the rear wall 106. Other attachment means are contemplated, such as hook-and loop fasteners, or other such attachment means, as shown in FIGS. 48 and 49. In an embodiment, the lid 112 may be secured to the rear wall 106 by using an attachment means (not shown) such as a hook-and-loop fastener, a pair of corresponding clips, or other such attachment means connected to the lid 112 and the rear wall 106.
A pair of handles 114a, 114b are attached to the front wall 104 and the rear wall 106, respectively. In use, the handles 114a, 114b extend above the lid 112 of the container 100 and may be used to carry the container 100. In an alternative embodiment, hand grips are attached to the opposing side walls 108, 110 and may be used to carry the container 100. In alternative embodiments, a hand grip 116 is also attached to the front wall 104 of the container 100 for carrying the container 100 in a collapsed configuration.
In an embodiment, the container 100 is insulated so as to maintain the temperature of the items stored or transported within the container 100. FIG. 10 depicts a cross-sectional illustration of the front wall 104 (not shown to scale). In an embodiment, the same five layers comprise the front wall 104, the rear wall 106, and the side walls 108, 110. The exterior layer 132 comprises a protective, relatively strong and durable synthetic or natural material such as a fabric, canvas, nylon, coated polyester, or the like. In an embodiment, the exterior layer 132 includes an aluminizing material or coating to better reflect and disperse radiation (such as heat) away from the container 100. The interior layer 138 comprises a waterproof material, such as polyethylene vinyl acetate (PEVA), or a plastic foil material. The outer middle layer 134 comprises a rigid or semirigid material, such as polyethylene (PE) board or PE-coated paperboard, to provide support for the container 100. The middle layer 136 comprises insulation, such as cotton insulation, an insulating foam, or a high-density polyethylene (HDPE) foam. In an embodiment, the middle layer 136 of the walls 104, 106, 108, 110 comprises a layer of insulation that is 2 centimeters thick. The inner middle layer 138 comprises a material for maintaining the temperature of the cavity of the container 100 and any items located therein (e.g., by either cooling or heating). In an embodiment, the inner middle layer 136 comprises a gel pack comprising an outer wrapper or envelope of flexible or pliable material such as plastic film which is filled with and surrounds an insulating, nontoxic gel material, which may be any such material known to those of skill in the art, such as silica gel. The amount of fill of the gel material is such that the gel pack is substantially flattened in shape. As will be clear to one of skill in the art from the present disclosure, in alternative embodiments, the structure of the walls 104, 106, 108, 110 may be varied to either include additional layers (such as by including additional layers of insulation) or omit layers (such as by omitting the outer middle layer 134 to provide a soft-sided container).
As shown, the exterior layer 132, the outer middle layer 134, the inner middle layer 138, and the interior layer 140 of adjacent wall panels are connected together, for example by side seams or lines of stitching 142 at the intersections of the side walls 108, 110 with the front wall 104, the base panel 102, and the rear wall 106. In an embodiment, the front wall 104, the side walls 108, 110, and the rear wall 106 comprise a single continuous length of multiple layered wall panel material with one or more discrete gel packs forming the inner middle layer 138 in each wall. Multiple discrete gel packs may be used for the inner middle layer 138. A single gel pack is located in each of the front wall 104 and the rear wall 106, with each gel pack extending substantially between the side walls 108, 110. A pair of gel packs are located in each of the side walls 108, 110, such that one gel pack is located in each side wall 108, 110 in the area between the front wall 104 and the crease 124a, 124b, and a second gel pack is located in each side wall 108, 110 in the area between the rear wall 106 and the crease 124a, 124b. The crease 124a, 124b is formed by side seams or lines of stitching extending through the exterior layer 132, the outer middle layer 134, the inner middle layer 138, and the interior layer 140 such that the separation between the gel packs in the side walls 108, 110 is maintained. In alternative embodiments, other structures of gel packs may be used. By way of example, a plurality of discrete gel packs may be located in each wall 104, 106, 108, 110, such as by using a grid of spaced-apart gel packs. Alternatively, each layer may stretch continuously around the container 100 (i.e., inner middle layer 138 may be formed from a single continuous gel pack).
In an embodiment, the base panel 102 and the lid 112 have substantially the same layered structure as the other walls, and each includes at least one gel pack in the inner middle layer 138. In an embodiment, the base panel 102 contains a plurality of discrete gel packs separated by the crease 126. In an alternative embodiment, the base panel 102 and/or the lid 112 omit the inner middle layer 138 and do not contain any gel packs. In other alternative embodiments, the base panel 102 also omits the outer middle layer 134 to better allow the base panel 102 to fold inward when the container 100 is folded.
In an embodiment, the base panel 102 comprises only the exterior layer 132, the middle layer 135 comprising insulation, and the interior layer 140. An interior flap 128 sits adjacent to the base panel 102 and is affixed to the front wall 104 so as to allow the interior flap 128 to fold upward against the front wall 104 when the container 100 is collapsed. Like the view shown in FIG. 10, the interior flap 128 comprises a shell 144, formed of a waterproof material such as polyethylene vinyl acetate (PEVA) or a plastic foil material, surrounding a first inner layer 146 proximate the cavity of the container 100 comprising a gel pack such as that used in the inner middle layer 136 and a second inner layer 148 comprising a rigid or semirigid material, such as polyethylene (PE) board or PE-coated paperboard. A pull tab 130 is attached to the interior flap 128 to enable the interior flap 128 to be easily folded against the front wall 104. In alternative embodiments, the interior flap 128 is attached to one of the rear wall 106, the side wall 108, or the side wall 110, permitting the interior flap 128 to fold against the respective wall 106, 108, 110. In alternative embodiments, the interior flap 128 omits the second inner layer and/or the base panel 102 includes an additional layer comprising a rigid or semirigid material, such as polyethylene (PE) board or PE-coated paperboard.
Insulated Delivery Container with Removable Gel Pack Insert
FIGS. 11 through 23 illustrate a second embodiment of a delivery container 1100 that further comprises a removable insert 1101. As shown, delivery container 1100 also comprises a base panel 102, a front wall 104, a rear wall 106, opposite side walls 108, 110, and a lid 112 and is generally similar to delivery container 100. A removable insert 1101 is sized so as to fit within the cavity of the container 1100. A pair of handles 1114a, 1114b are attached to the side walls 108, 110 and the base panel 102. In use, the handles 1114a, 1114b extend above the lid 112 of the container 1100 and may be used to carry the container 1100.
As shown, the insert 1101 generally comprises a rectangular structure having a base panel 1102, a front wall 1104, a rear wall 1106, and opposite side walls 1108, 1110, which together define a cavity. The insert 1101 is shaped and sized so as to be placed in the cavity of the container 1100 such that the base panel 1102 of the insert is proximate the base panel 102 of the container 1100; items to be transported or stored in the container 1100 (such as, but not limited to, articles of food, beverages, and the like) are then placed within the cavity of the insert 1101. In other embodiments (not shown), the container 1100 and the insert 1101 may take other shapes, so long as the insert 1101 is sized and shaped so as to fit within the container 1100.
As shown, in embodiments the insert 1101 is collapsible to permit the container 1100 and the insert 1101 to be easily transported or stored while empty. As shown, vertical creases 1124a, 1124b extend along the side walls 1108, 1110 from proximate the base panel 1102 to proximate the open top of the insert 1101 to facilitate folding of the side walls 1108, 1110 when the insert 1101 is collapsed. The base panel 1102 also includes one or more creases 1126 to facilitate folding the base panel 1102. To collapse the insert 1101, the base panel 1102 folds into the insert 1101 along the creases 1126, while the side walls 1108, 1110 fold into the insert 1101 along creases 1124a, 1124b such that the front wall 1104 moves towards the rear wall 1106. The base panel 1102 further includes a pull tab 1130 to permit the base panel 1102 to be easily folded into the insert 1101. In an embodiment, the front wall 1104 and the rear wall 1106 contain horizontal creases, and the insert 1101 may be folded about the horizontal creases such that the base panel 1102 is proximate the open end of the insert 1101.
Once the insert 1101 is collapsed, it may be placed within the cavity of the container 1100. Optionally, the container 1100 may also be collapsed as discussed above. Alternatively, the container 1100 may be used without the insert 1101, such as when the contents of the container 1100 do not need to be temperature controlled.
In an embodiment, the container 1100 is insulated so as to maintain the temperature of the items stored or transported within the container 1100, and the insert 1101 comprises a material for maintaining the temperature of the cavity of the insert 1101. As shown in FIG. 23, the base panel 102, front wall 104, rear wall 106, side walls 108, 110, and lid 112 each comprise four distinct layers. The exterior layer 132 comprises a protective, relatively strong and durable synthetic or natural material such as a fabric, canvas, nylon, coated polyester, or the like. In an embodiment, the exterior layer 132 includes an aluminizing material or coating to better reflect and disperse radiation (such as heat) away from the container 1100. The interior layer 138 comprises a waterproof material, such as polyethylene vinyl acetate (PEVA) or a plastic foil material. The outer middle layer 134 comprises a rigid or semirigid material, such as polyethylene (PE) board or PE-coated paperboard, to provided support for the container 1100. The middle layer 136 comprises insulation, such as cotton insulation, an insulating foam, or a high-density polyethylene (HDPE) foam.

Insulated Secure Container
FIGS. 50a and 51a illustrate an eighth embodiment of a delivery container 5000 that is generally similar in structure to delivery container 100 but with several notable distinctions. As shown, the container 5000 generally comprises a rectangular structure having a base panel 5002, a front wall 5004, a rear wall 5006, opposite side walls 5008, 5010, and a lid 5012, which together define a cavity which receives items to be transported or stored in the container 5000.
In other embodiments (not shown), the container 5000 may take other shapes. By way of example and not of limitation, in other embodiments, the container 5000 may have a greater or lesser number of walls (e.g., being cylindrical in shape and having only a single side wall, or being polyhedral and having additional walls).
As shown, the lid 5012 is movably attached to the rear wall 5006 such that the lid 5012 may be folded away from the side walls 5008, 5010 and the front wall 5004 to permit access to the cavity within the container. In the embodiment shown, the lid 5012 may be folded flush against the rear wall 5006 such that the top surface of the lid 5012 is proximate the exterior surface of the rear wall 5006. In this manner, when opened, the lid 5012 does not block access to the cavity within the container. Advantageously, this structure ensures that the distance that must be traveled by air outside the container 5000 in order to come into contact with the interior of the container 5000 (particularly the interior of the rear wall 5006) is minimized when the lid 5012 is opened. As a result, the time required to cool the interior of the container (e.g., to freeze gel packs or other freezable medium contained in one or more of the walls of the container, as discussed below) is substantially reduced as opposed to alternative designs, wherein the lid blocks at least a portion of the opening while in an open position. In alternative embodiments, the lid 5012 may be attached to a different one of the walls 5004, 5006, 5008, 5010 or may be removably attached to multiple of the walls 5004, 5006, 5008, 5010.
In an embodiment, a flap or lip 5022 extends from the lid 5012 towards the base panel 5002 such that the flap 5022 overlaps the portion of the side walls 5008, 5010 and the front wall 5004 proximate the lid 5012. As shown, the flap 5022 comprises a front lip 5022a that overlaps the front wall 5004 and a pair of side lips 5022b, 5022c that each overlap a respective one of the side walls 5008, 5010. In embodiments where the lid 5012 is not attached to the rear wall 5006 along the entirety of the top edge of the rear wall 5006, the flap may further comprise one or more rear lips (not shown) that each overlap at least a portion of the rear wall 5006 where the lid 5012 is not connected to the rear wall 5006. In an embodiment, as shown in FIGS. 50a and 51a, a fastener 5062a, 5062b comprise one or more elements may be used to removably attach the lid 5012 to one or more of the walls 5004, 5008, 5010 so as to prevent the lid 5012 from being inadvertently lifted while the container 5000 is in use (e.g., while the container 5000 is being used to store or transport items). In embodiments, each fastener 5062a, 5062b may comprise pairs of magnets, a hook-and-loop fastener, a pair of clips, cooperative buttons, interlocking elements, a string tied to a corresponding projection, or the like. One portion of the fastener 5062a is attached to the lid 5012, while a second portion of the fastener 5062b is attached to one of the walls 5004, 5006, 5008. As shown in FIGS. 50a and 51a, said fastener may be pairs of corresponding magnets 5062a, 5062b positioned on the side lips 5022b, 5022c of the lid 5012 and on corresponding side walls 5008, 5010 proximate the opening so as to allow the lid 5012 to be detachably secured to the side walls 5008, 5010. In the embodiment shown, the magnets 5062a, 5062b pull the side walls 5008, 5010 flush against the flap 5022 when the lid 5012 is closed, thereby forming a seal that better resists the flow of air from outside the container 5000 to the cavity of the container 5000. This design improves the insulating properties of the container 5000, allowing items kept in the container 5000 to maintain a desired temperature for a greater duration of time regardless of the temperature outside the container 5000.
As shown in FIGS. 52, 71, and 72, in embodiments the container 5000 is collapsible to permit the container 5000 to be easily transported or stored while empty. As shown, vertical creases 5024a, 5024b extend along the side walls 5008, 5010 from proximate the base panel 5002 to proximate the front wall 5004 to facilitate folding of the side walls 5008, 5010 when the container 5000 is collapsed. The base panel 5002 also includes one or more creases 5026 to facilitate folding the base panel 5002. To collapse the container 5000, the base panel 5002 folds into the container 5000 along the creases 5026 while the side walls 5008, 5010 fold into the container 5000 along creases 5024a, 5024b such that the front wall 5004 moves towards the rear wall 5006. In an embodiment, once the container 5000 is collapsed, the lid 5012, attached to the rear wall 5006, folds so that the top of the lid 5012 is nearer to the rear wall 5006 of the container 5000, thereby allowing airflow through the opening of the container 5000 into the cavity when the container 5000 is collapsed.
In an embodiment, at least a portion of the container 5000 is insulated so as to maintain the temperature of the items stored or transported within the container. In the embodiment shown, the entirety of the container 5000 comprises an exterior layer 5032 and an interior layer 5038. As shown in cross-sectional view 50b (not to scale), the flap 5022 comprises one or more magnets 5062b located between the interior layer 5038 and the exterior layer 5032. In the embodiment shown, the interior layer 5038 of the flap 5022 comprises the same material as the exterior layer 5032. In an alternative embodiment (not shown), the lid 5012 further comprises a layer of insulation and/or a support member or stiffener located between the interior layer 5038 and the exterior layer 5032 on at least a portion of the top surface of the lid 5012, the flap 5022, or both. As shown in cross-sectional view 50c (not to scale), the side walls 5008, 5010 each comprise an interior layer 5038, a layer of insulation 5036, and an exterior layer 5032. One or more magnets 5062a are located proximate the opening of the container 5000 between the exterior layer 5032 and the layer of insulation 5036.
As shown in cross-sectional view 51c (not to scale), when the lid 5012 is in the closed position, the magnets 5062a, 5062b are proximate one another and press the exterior layer 5032 of the sidewalls 5008, 5010 against the interior layer 5038 of the flap 5022, thereby decreasing the rate at which air outside the container 5000 may enter the cavity. As shown in cross-sectional view 51d (not to scale), the front wall 5004 comprises an interior layer 5038, a freezable medium 5034 such as a gel pack, a layer of insulation 5036, a stiffener or support member 5030, and an exterior layer 5032. The rear wall 5006 may comprise substantially the same layers as the front wall 5004.
In the embodiment shown, a loop 5072 formed from a strap 5001 is connected to the exterior surface of the front wall 5004 proximate the opening of the container 5000. A corresponding loop 5070 extends from a second strap 5003 connected to the front lip 5022a of the flap 5022 and is located such that when the lid 5012 is in the closed position, the loops 5070, 5072 are located proximate one another. A connector (such as a hook-and-loop connector) may be located on the interior surface of the lid strap 5003 and on the exterior surface of the front wall strap 5001. As discussed in greater detail below, a security element (such as a zip-tie or cable tie) may be used to securely connect the loops 5070, 5072 together, thereby securing the lid 5012 in the closed position. In an embodiment, the security element cannot be removed (and thus the container 5000 cannot be opened and the contents of the container 5000 cannot be accessed) without cutting or otherwise damaging the security element, thereby allowing a user of the container to readily determine whether the container 5000 has been opened or the contents of the container 5000 tampered with since the security element was put in place.
In an embodiment, as shown in FIG. 58, an inner middle layer 5034 comprises a material for maintaining the temperature of the cavity of the container 5000 and any items located therein (e.g., by either cooling or heating). In an embodiment, the inner middle layer 5034 comprises a gel pack comprising an outer wrapper or envelope of flexible or pliable material such as plastic film which is filled with and surrounds an insulating, nontoxic gel material, which may be any such material known to those of skill in the art, such as silica gel. The amount of fill of the gel material is such that the gel pack is substantially flattened in shape. As will be clear to one of skill in the art from the present disclosure, in alternative embodiments, the structure of the walls 5004, 5006, 5008, 5010 may be varied to either include additional layers (such as by including additional layers of insulation) or omit layers (such as by omitting the outer middle layer 5030 to provide a soft-sided container).
In an embodiment, the exterior layer 5032 comprises a protective, relatively strong and durable synthetic or natural material such as a fabric, canvas, nylon, coated polyester, or the like. In an embodiment, the exterior layer 5032 includes a reflective coating such as an aluminizing material or coating to better reflect and disperse radiation (such as light and heat) away from the container 5000. In an embodiment, the interior layer 5038 comprises a waterproof material, such as polyethylene vinyl acetate (PEVA), or a plastic foil material. In an embodiment, the layer of insulation 5036 comprises flexible insulation, such as cotton insulation, an insulating foam, or a high-density polyethylene (HDPE) foam. In an embodiment, the layer of insulation 5036 in the walls 5004, 5006, 5008, 5010 comprises a layer of insulation that is 2 centimeters thick.
In an embodiment, as shown in FIG. 58, an inner middle layer 5034 comprises a material for maintaining the temperature of the cavity of the container 5000 and any items located therein (e.g., by either cooling or heating). In an embodiment, the inner middle layer 5034 comprises a gel pack comprising an outer wrapper or envelope of flexible or pliable material such as plastic film which is filled with and surrounds an insulating, nontoxic gel material, which may be any such material known to those of skill in the art, such as silica gel. The amount of fill of the gel material is such that the gel pack is substantially flattened in shape. As will be clear to one of skill in the art from the present disclosure, in alternative embodiments, the structure of the walls 5004, 5006, 5008, 5010 may be varied to either include additional layers (such as by including additional layers of insulation) or omit layers (such as by omitting the outer middle layer 5030 to provide a soft-sided container).
In an embodiment, as shown in FIGS. 60 and 61, the middle layer 5036 comprises an additional layer of flexible insulation, nearer to the opening of the cavity of the container 5000 than the inner layer 5034 comprising a material for maintaining the temperature of the cavity of the container 5000. In some embodiments, as shown in FIGS. 61, 62, 64, and 66, one or more of the walls 5004, 5006, 5008, 5010 of the container 5000 comprises an additional band of fabric 5040, made of mesh webbing or the like, extending along the top of each wall along the opening of the container 5000, thereby providing additional support along the opening of the cavity when the container 5000 is in use.
In an embodiment, as shown in FIGS. 63 and 64, the middle layer 5036 comprises an additional layer of flexible insulation, nearer to the opening of the cavity of the container 5000 than an outer middle layer 5030 comprising a rigid or semirigid material, such as polyethylene (PE) board or PE-coated paperboard, to provide support for the container 5000 when in use.
In an embodiment, as shown in FIGS. 65 and 66, each of the outer middle layer 5030, middle layer 5036, and inner middle layer 5034 does not extend to the opening of the container 5000.
In some embodiments, a tamper-resistant clasp, as shown in FIGS. 50a through 66 and 69a through 70c, comprising a mechanism such as a pair of loops or the like 5070 and 5072 where a securing mechanism such as a zip-tie, bolt, lock, or the like may be inserted into the loops as shown in FIGS. 70b and 70c and secured so as to prevent unauthorized access to the contents and notification to the user that the contents have not been tampered with.
In some embodiments, a pair of handles 5014a, 5014b are attached optionally to the opposing side walls 5008, 5010. In use, the handles 5014a, 5014b extend above the lid 5012 of the container 5000 and may be used to carry the container 5000. In addition, or alternatively, hand grips 5018 are attached to the opposing side walls 5008, 5010 and may be used to carry the container 5000. A hand grip may also be attached to the front wall 5004 of the container 5000 for carrying the container 5000 in a collapsed configuration.
An ID card holder 5016 is optionally located on the container 5000, for example to allow for identification of the owner of the container 5000 or the contents of the container 5000. The ID card holder 5016 may comprise a clear material, such as a clear plastic, to permit writing on an object placed in the ID card holder 5016 to be clearly visible.
In an embodiment of the container 5000, as shown in FIGS. 67a, 67b, 67c, and 67d, which comprises a different lid configuration, side flaps 6714a, 6714b extend from the opposing side walls 5008, 5010 so that they may be folded into the cavity to double the material nearest the opening of the cavity of the container 5000. Additional front and back lids 6712a, 6712b extend from the front wall 5004 and the rear wall 5006 such that when they are folded over the cavity of the container 5000, they rest on the doubled material created from the side flaps 6714a, 6714b such that they form a lid to the container 5000 and do not collapse into the cavity, as shown in FIGS. 67c and 67d. The front and back lids 6712a, 6712b each contain a latching mechanism, such as a hook-and-loop fastener, on the interior and exterior of the lid, respectively, so as to prevent the lids 6712a, 6712b from being inadvertently lifted while the container 5000 is in use.
In an embodiment of the container 5000, as shown in FIGS. 68a, 68b, 68c, and 68d, which comprises a different lid configuration, soft-sided gussets 6814a, 6811b extend from the opposing side walls 5008, 5010, and front and back lids 6812a, 6812b extend from the front wall 5004 and the rear wall 5006 such that when the front and back lids 6812a, 6812b are folded over the cavity, the soft-sided gussets 6811a, 6814b collapse into the cavity of the container 5000 and provide support to the front and back lids, as is shown in FIGS. 68b through 68d. Alternatively, when the front and back lids 6812a, 6812b are not folded over the cavity, the soft-sided gussets 6814a, 6814b provide tension against the front and back lids 6812a, 6812b, thereby freeing the opening of the cavity of the container 5000 while it is being filled.
