Abstract

The invention is a collapsible container that transitions between an open configuration for use and a closed configuration for compact storage. It features strategically placed fold lines on its surfaces, which may form one or more triangular-shaped regions that facilitate an inward folding of the material forming the surface. These fold lines guide the material to fold in a specific manner when the container is collapsed thus ensuring the materials of the surface are disposed within the interior of the container when it is collapsed.

Description

This application claims priority to U.S. provisional patent application having Ser. No. 63/567,823 filed on Mar. 20, 2024. This and all other referenced extrinsic materials are incorporated herein by reference in their entirety. Where a definition or use of a term in a reference that is incorporated by reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein is deemed to be controlling.

FIELD OF THE INVENTION

The field of the invention is portable storage solutions, and in particular collapsible containers.

BACKGROUND

The following description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Storage containers are generally used for holding, storing, and/or transporting items within the container. Containers can be made from a range of materials and sometimes can have a lid or a handle. One type of container is a portable cooler, which is an insulated container that is designed to be portable while insulating an interior of the container from an ambient environment.
Traditional storage containers have been designed with a focus on rigidity and protection, often resulting in fixed, bulky structures that are not easily stored or transported when not in use. As a result, collapsible containers have been introduced that allow for easier storage of the containers when not in use.
Existing collapsible containers, especially soft-shell containers, often come with a set of challenges. The ability to easily collapse the soft-shell container has generally led to the containers being less insulative because they may utilize materials and construction methods that do not provide adequate insulation to keep contents cold for extended periods. In addition, many collapsible coolers may not maintain their shape well when loaded, leading to potential spillage or damage to the contents.
All publications identified herein are incorporated by reference to the same extent as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
Thus, there is still a need for improved, collapsible containers that can be stored away better, carrier easier, and function better, particularly in terms of their collapsibility and the ease with which they can be transitioned between expanded and compacted states.

SUMMARY OF THE INVENTION

The inventive subject matter provides apparatus, systems, and methods for collapsible containers designed to offer a convenient and space-efficient solution for the insulated storage and transportation of items. Preferred containers are capable of transitioning between an expanded, open configuration and a compact, closed configuration. Such containers comprise a body having a bottom surface, a front surface, a back surface, a left surface, and a right surface. The container may also include a top surface or lid that may be coupled to one of the front surface, a back surface, a left surface, and a right surface.
The bottom surface, front surface, back surface, left surface, and right surface collectively define an interior cavity, which can be used to store various goods, for example. Preferably, the interior cavity is insulated from an ambient environment.
Preferred collapsible containers are quickly and easily transitioned from an expanded configuration to a collapsed configuration, significantly reducing its footprint and making it more convenient for storage in limited spaces. Specifically, the container's fold lines function to guide the material forming the sidewalls to fold inwardly in a predictable manner, simplifying the process and allowing for quick and effortless collapsing and expanding of the container.
It is preferred that the front and back surfaces each comprises a first set of fold lines. The left and right surfaces may comprise a second set of fold lines. The first and second sets of fold lines on the respective surfaces advantageously cause material forming each of the front surface, back surface, left surface, and right surface to fold inwardly when the body is collapsed from an open (upright) configuration to a closed (compacted) configuration. Specifically, the fold lines define lines along which the material will fold when the body is collapsed and bias the material in an inward direction (i.e., toward the interior cavity). The claimed invention's internalized folding technology ensures that the containers fold along the predetermined lines, which helps to prolong the life of the container and maintain a neat appearance when collapsed.
The fold lines may be formed through various methods. As one example, the fold lines may be sewn into the material forming each of the front surface, back surface, left surface, and right surface.
The folding technology described herein is preferably internalized within the container's body, with the body not only providing insulation to contents with the interior cavity, but also intentional folding lines that enable the container to collapse quickly and with minimal effort and result in the material(s) of the sidewalls being folded internally within the container. The collapsible container thereby provides a more user-friendly and space-efficient alternative to existing collapsible coolers.
Various objects, features, aspects, and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawing figures in which like numerals represent like components.

DETAILED DESCRIPTION

The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus, if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.
The present invention pertains to a collapsible container that exhibits a novel approach to portable storage that provides insulation to the stored goods by addressing the challenges associated with traditional rigid and non-collapsible coolers. The invention comprises a collapsible container that can transition between an open configuration, suitable for storing and transporting items, and a closed configuration, which significantly reduces the container's footprint for convenient storage when not in use.
FIGS. 1A-1I illustrate one embodiment of a collapsible container 100 or insulated container. The container 100 comprises a top surface 114 and a bottom surface 104 that are connected by one or more sides to form the container 100 and define an interior cavity 120. Specifically, the collapsible container 100 is characterized by a body 102 that includes the bottom surface 104 and a front surface 106, a back surface 108, a left surface 110, and a right surface 112 connected thereto. These surfaces collectively define the interior cavity 120 that serves as a storage space.
Thus, the collapsible container 100 can comprise two sets of opposing sidewalls (e.g., front/back surfaces and left/right surfaces). Each set of opposing sidewalls is preferably identical to one another.
The top surface 114 may be hingedly or otherwise coupled to one or more of the front surface 106, a back surface 108, a left surface 110, and a right surface 112. The top surface 114 is configured to transition between the closed configuration restricting access to the interior cavity 120 (shown in FIG. 1A) to an open configuration allowing access to the interior cavity 120 (shown in FIG. 1C). Thus, the top surface 114 or cover can be opened or closed as needed. In some embodiments, it is contemplated that the top surface 114 can be closed via a zipping mechanism, although snaps, straps, and other closure mechanisms could alternatively be used.
As shown in FIGS. 1A-1C, the collapsible container 100 may include one or more handles 160 attached to the body 102 to permit ease of carrying of the container 100.
In some embodiments, the collapsible container 100 may optionally include an elastic strap 162 that can be wrapped around at least a portion of the container 100 when collapsed to maintain the container 100 in its collapsed configuration due to the downward force exerted on the container 100 by the elastic strap 162. In the embodiment shown in FIG. 1B, the elastic strap 162 is shown attached to opposing ends of the bottom surface 104 and wraps around the top surface 114.
In preferred embodiments, each of the top and bottom surfaces are formed from a rigid material, such as an injection molded plastic or polycarbonate, although any commercially suitable material(s) could be used. In contrast, the sidewalls of the container (i.e., front surface 106, a back surface 108, a left surface 110, and a right surface 112) are preferably formed of one or more flexible materials. It is contemplated that the container 100 can be manufactured from eco-friendly materials, such as recyclable materials.
Preferred containers are constructed to be watertight and airtight when closed and utilize high-performance thermal materials to insulate the interior cavity 120 from the ambient environment.
FIG. 1A illustrates the container 100 in an expanded configuration, while FIG. 1B illustrates the container 100 in a collapsed configuration. FIG. 1C shows the container 100 with the top cover 114 opened (or unzipped) to allow access to the interior cavity 120.
FIG. 1D illustrates an exploded view of the container 100. An exterior covering 103 is attached to the bottom surface 104 and covers the front surface 106, a back surface 108, a left surface 110, and a right surface 112. Top surface 114 can be coupled to the exterior covering 103.
The container 100 may include a rim 164, which may comprise a rigid upper frame that provides a sturdy structural opening for items to be placed within the interior cavity 120. In one embodiment, the rim 164 is a rectangular-shaped metal piece with rounded corners.
The container 100 may further include a waterproof liner 180 that is configured to be placed within the body 102 and line the bottom and sidewalls of the interior cavity 120 to contain any liquid within the interior cavity 120.
Each of the front surface 106 and the back surface 108 comprises a first set of fold lines 140. In the embodiment shown in FIGS. 1D-1I, the first set of fold lines 140 comprises a first line segment 141 and a second line segment 142. The first line segment 141 extends from a bottom, left portion near the bottom and left surfaces 104, 110 to a middle region of the front surface 106. The second line segment 142 extends from a top, left portion near the left surface 110 and opposite the bottom surface 104 to the middle region of the front surface 106. The first line segment 141 and the second line segment 142 intersect at a first apex 143.
The first set of fold lines 140 further comprises a third line segment 144 and a fourth line segment 145. The third line segment 144 extends from a bottom, right portion near the bottom and right surfaces 104, 112 to a middle region of the front surface 106. The fourth line segment 145 extends from a top, right portion near the right surface 112 and opposite the bottom surface 104 to the middle region of the front surface 106. The third line segment 144 and the fourth line segment 145 intersect at a second apex 146.
The first set of fold lines 140 further comprises a fifth line segment 147 extending between the first apex 143 and the second apex 146. The fifth line segment 147 is shown connecting the first apex 143 and the second apex 146 although alternative embodiment may have the fifth line segment 147 not connecting the first apex 143 and the second apex 146.
In some embodiments, the left side 148 of the front surface 106, the first line segment 141, and the second line segment 142 collectively define a first triangular-shaped region. In a similar manner, the right side 149 of the front surface 106, the third line segment 144, and the fourth line segment 145 collectively define a second triangular-shaped region. In such embodiments, the left side 148 of the front surface 106 defines a hypotenuse of the first triangular-shaped region, and the right side 149 of the front surface 106 defines a hypotenuse of the second triangular-shaped region.
Preferably, the first set of fold lines 140 are identically disposed on each of the front surface 106 and the back surface 108.
Each of the left surface 110 and the right surface 112 comprises a second set of fold lines 150. It is preferred that the second set of fold lines 150 are identically disposed on each of the left surface 110 and the right surface 112. In the embodiment shown in Figures ID-1I, the second set of fold lines 150 on either the left surface 110 or the right surface 112 comprises a sixth line segment 151 and a seventh line segment 152. The sixth line segment 151 extends from a bottom, left portion near the back and bottom surfaces 108, 104 to a middle region of the left surface 110. The seventh line segment 152 extends from a top, left portion near the back surface 108 and opposite the bottom surface 104 to the middle region of the left surface 110. The sixth line segment 151 and the seventh line segment 152 intersect at a third apex 153.
The second set of fold lines 150 further comprises an eighth line segment 154 and a ninth line segment 155. The eighth line segment 154 extends from a bottom, right portion near the bottom and front surfaces 104, 106 to a middle region of the left surface 110. The ninth line segment 155 extends from a top, right portion near the front surface 106 and opposite the bottom surface 104 to the middle region of the left surface 110. The eighth line segment 154 and the ninth line segment 155 intersect at a fourth apex 156.
The second set of fold lines 150 further comprises a tenth line segment 157 that horizontally extends across the left surface 110. It is contemplated that the tenth line segment 157 intersects both the third apex 153 and the fourth apex 156.
In some embodiments, the left side of the left surface 110 (nearest the back surface 108), the sixth line segment 151, and the seventh line segment 152 collectively define a third triangular-shaped region. In a similar manner, the right side of the left surface 110 (nearest the back surface 106), the eighth line segment 154, and the ninth line segment 155 collectively define a fourth triangular-shaped region. In such embodiments, the left side of the left surface 110 defines a hypotenuse of the third triangular-shaped region, and the right side of the left surface 110 defines a hypotenuse of the fourth triangular-shaped region. Thus, the hypotenuse of the third triangular-shaped region may be disposed along the back surface 108, and a hypotenuse of the fourth triangular-shaped region may be disposed along the front surface 106.
Preferably, the second set of fold lines 150 are identically disposed on each of the left surface 110 and the right surface 112.
The second set of fold lines 150 may further comprise first and second vertical lines 170 and 172, which are preferably disposed parallel to one another. It is contemplated that the first vertical line 170 may intersect the third apex 153 and extend from a top portion of the left surface 110 to a bottom portion of the left surface 110. In a similar manner, the second vertical lines 172 may intersect the fourth apex 156 and extend from a top portion of the left surface 110 to a bottom portion of the left surface 110.
The first set of fold lines 140 and the second set of fold lines 150 are each strategically placed on the body 102 to enable the materials forming the sidewalls of the body 102 to fold inwardly (i.e., into the interior cavity 120), thereby collapsing the container 100 efficiently from its open configuration to its closed configuration. Specifically, the first and second sets of fold lines 140, 150 cause the materials forming each of the front surface 106, back surface 108, left surface 110, and right surface 112 to fold inwardly when the body 102 is collapsed from the open configuration to the closed configuration.
It is contemplated, though not required, that the container 100 further comprises first and second snap hinges 190, each disposed on opposing sides of the container 100. The snap hinges 190 assist with maintaining the container 100 in the expanded configuration and to collapse the container 100 when desired. The snap hinges 190 may also provide a connection between the bottom surface 104 and the rim 164 and provide a snap opening and closing features of the container 100.
In one example, the snap hinges 190 are comprised of structural grade polymers. As with most hinges, the hinges 190 are comprised of two pieces joined by a metal pin. The hinges 190 produce a “spring” effect upwards and “snap” sound upon the hinges 190 being fully extended. The hinges 190 also produce a snap sound upon the hinges 190 starting to collapse. The spring effect and snap sound are caused by a short section of spring steel which is inserted into a slot of each of the two hinges 190. The hinges 190 can facilitate expanding the container 100 by pressing the center of the hinges 190 outward or by a quick upward pull to the handles 160 or the rim 164, for example. The hinges 190 can facilitate collapsing the container 100 by pressing the center of the hinges 190 inwardly.
As shown in FIGS. 1E-1H, one snap hinge 190 may be disposed on the left surface 110 of the body 102 and the other snap hinge 190 may be disposed on the right surface 112 of the body 102. Preferably, each snap hinge 190 is disposed between the parallel, vertical fold lines 170, 172.
FIGS. 1E-1I illustrate the container 100 transitioning from the expanded configuration shown in FIG. 1E to the collapsed configuration shown in FIG. 1I. As shown in FIG. 1F, one or more forces F can be applied to the container 100 to cause the container 100 to begin to collapse. As the container 100 collapses, the materials of each of the front surface 106 and back surface 108 and the left surface 110 and right surface 112 begins to move inwardly and fold along the first and second sets of fold lines 140, 150, respectively. The collapse of the container 100 continues in FIGS. 1G and 1H.
FIG. 1I illustrates the container 100 in the collapsed configuration. As can be seen, each of the front surface 106 and back surface 108 and the left surface 110 and right surface 112 are folded and disposed within an interior of the container 100. The front surface 106 and the back surface 108 are folded to form a trapezoid shape, while the left surface 110 and the right surface 112 are folded to form a triangle shape.
FIG. 2 illustrates an exploded view of the front surface 106 and the right surface 112. As shown, it is contemplated that each of the front surface 106, back surface 108, left surface 110, and right surface 112 can be composed of multiple materials. As one example, each of the surfaces 106, 108, 110, 112 may be composed of an inner foil lining 210, a non-woven material layer 212, a foam layer 214, and an outer foil lining 216. Of course, the specific order of materials, and types of materials, used can vary depending on the application.
In some embodiments, it is contemplated that the first set of fold lines 140 on the front and back surfaces 106, 108 may be formed by stitching that extends through each of the inner foil lining 210, a non-woven material layer 212, a foam layer 214, and an outer foil lining 216 forming the front and back surfaces 106, 108. In a similar manner, the second set of fold lines 150 on the left and right surfaces 110, 112 may be formed by stitching that extends through each of the inner foil lining 210, a non-woven material layer 212, a foam layer 214, and an outer foil lining 216 forming the left and right surfaces 110, 112.
It is further contemplated that the foam layer 214 may be thinner of the left and right surfaces 110, 112 may be thinner in the region where the snap hinge 190 is disposed. Alternatively, the layer may comprise three separate pieces with the left and right pieces being thicker than the middle piece. In some embodiment, the snap hinge may be disposed outside of the outer foil lining 216.
FIG. 3 illustrates another embodiment of a collapsible container 300 comprising a top surface 314 and a bottom surface 304 that are connected by one or more sides to form the container 300 and define an interior cavity 320. Specifically, the collapsible container 300 is characterized by a body 302 that includes the bottom surface 304 and a front surface 306, a back surface 308, a left surface 310, and a right surface 312 connected thereto. These surfaces collectively define the interior cavity 320 that serves as a storage space. Each set of opposing sidewalls is preferably identical to one another.
The top surface 314 may be hingedly or otherwise coupled to one or more of the front surface 306, a back surface 308, a left surface 310, and a right surface 312. The top surface 314 is configured to transition between the open configuration shown in FIG. 3 to a closed configuration. It is contemplated that the top surface 314 can be closed via a zipping mechanism, although snaps, straps, and other closure mechanisms could alternatively be used.
In preferred embodiments, each of the top and bottom surfaces 304, 314 are formed from a rigid material, such as an injection molded plastic or polycarbonate, although any commercially suitable material(s) could be used. In contrast, the sidewalls of the container (i.e., front surface 306, back surface 308, left surface 310, and right surface 312) are preferably formed of one or more flexible materials. It is contemplated that the container 300 can be manufactured from eco-friendly materials, such as recyclable materials.
The container 300 may include a rim 364, which may, comprise a rigid upper frame that provides a sturdy structural opening for items to be placed within the interior cavity 320. In one embodiment, the rim 364 is a rectangular-shaped meal piece with rounded corners.
Each of the front surface 306 and the back surface 308 comprises a first set of fold lines 340. The first set of fold lines 340 comprises a first line segment 341 and a second line segment 342. The first line segment 341 extends from a bottom, left portion near the bottom and left surfaces 304, 310 to a middle region of the front surface 306. The second line segment 342 extends from a top, left portion near the left surface 310 and opposite the bottom surface 304 to the middle region of the front surface 306. The first line segment 341 and the second line segment 342 intersect at a first apex 343.
The first set of fold lines 340 further comprises a third line segment 344 and a fourth line segment 345. The third line segment 344 extends from a bottom, right portion near the bottom and right surfaces 304, 312 to a middle region of the front surface 306. The fourth line segment 345 extends from a top, right portion near the right surface 312 and opposite the bottom surface 304 to the middle region of the front surface 306. The third line segment 344 and the fourth line segment 345 intersect at a second apex 346.
The first set of fold lines 340 further comprises a fifth line segment 347 extending between the first apex 343 and the second apex 346. The fifth line segment 347 is shown connecting the first apex 343 and the second apex 346 although alternative embodiment may have the fifth line segment 347 not connecting the first apex 343 and the second apex 346.
In some embodiments, the left side 348 of the front surface 306, the first line segment 341, and the second line segment 342 collectively define a first triangular-shaped region. In a similar manner, the right side 349 of the front surface 306, the third line segment 344, and the fourth line segment 345 collectively define a second triangular-shaped region. In such embodiments, the left side 348 of the front surface 306 defines a hypotenuse of the first triangular-shaped region, and the right side 349 of the front surface 306 defines a hypotenuse of the second triangular-shaped region.
Preferably, the first set of fold lines 340 are identically disposed on each of the front surface 306 and the back surface 308.
Each of the left surface 310 and the right surface 312 comprises a second set of fold lines 350. It is preferred that the second set of fold lines 350 are identically disposed on each of the left surface 310 and the right surface 312. The second set of fold lines 350 comprises a sixth line segment 351 and a seventh line segment 352. The sixth line segment 351 extends from a bottom, left portion near the back and bottom surfaces 308, 304 to a middle region of the left surface 310. The seventh line segment 352 extends from a top, left portion near the back surface 308 and opposite the bottom surface 304 to the middle region of the left surface 310. The sixth line segment 351 and the seventh line segment 352 intersect at a third apex 353.
The second set of fold lines 350 further comprises an eighth line segment 354 and a ninth line segment 355. The eighth line segment 354 extends from a bottom, right portion near the bottom and front surfaces 304, 306 to a middle region of the left surface 310. The ninth line segment 355 extends from a top, right portion near the front surface 306 and opposite the bottom surface 304 to the middle region of the left surface 310. The eighth line segment 354 and the ninth line segment 355 intersect at a fourth apex 356.
The second set of fold lines 350 further comprises a tenth line segment 357 that horizontally extends across the left surface 310 from a left side to a right side of the left surface 310. It is contemplated that the tenth line segment 357 intersects both the third apex 353 and the fourth apex 356.
In some embodiments, the left side of the left surface 310 (nearest the back surface 308), the sixth line segment 351, and the seventh line segment 352 collectively define a third triangular-shaped region. In a similar manner, the right side of the left surface 310 (nearest the back surface 306), the eighth line segment 354, and the ninth line segment 355 collectively define a fourth triangular-shaped region. In such embodiments, the left side of the left surface 310 defines a hypotenuse of the third triangular-shaped region, and the right side of the left surface 310 defines a hypotenuse of the fourth triangular-shaped region. Thus, the hypotenuse of the third triangular-shaped region may be disposed along the back surface 308, and a hypotenuse of the fourth triangular-shaped region may be disposed along the front surface 306.
Preferably, the second set of fold lines 350 are identically disposed on each of the left surface 310 and the right surface 312.
The second set of fold lines 350 may further comprise first and second vertical lines 370 and 372, which are preferably disposed parallel to one another. It is especially preferred that the vertical lines 370, 372 are spaced apart such that a snap hinge may be disposed between the vertical lines 370, 372. It is contemplated that the first vertical line 370 may intersect the third apex 353 and extend from a top portion of the left surface 310 to a bottom portion of the left surface 310. In a similar manner, the second vertical lines 372 may intersect the fourth apex 356 and extend from a top portion of the left surface 310 to a bottom portion of the left surface 310.
As discussed above, the first set of fold lines 340 and the second set of fold lines 350 are each strategically placed on the body 302 to enable the materials forming the sidewalls of the body 302 to fold inwardly (i.e., into the interior cavity 320), thereby collapsing the container 300 efficiently from its open configuration to its closed configuration.
FIG. 4 illustrates another embodiment of a collapsible container 400 comprising a top surface 414 and a bottom surface 404 that are connected by one or more sides to form the container 400 and define an interior cavity 420. Specifically, the collapsible container 400 is characterized by a body 402 that includes the bottom surface 404 and a front surface 406, a back surface 408, a left surface 410, and a right surface 412 connected thereto. These surfaces collectively define the interior cavity 420 that serves as a storage space. Each set of opposing sidewalls is preferably identical to one another.
The top surface 414 may be hingedly or otherwise coupled to one or more of the front surface 406, a back surface 408, a left surface 410, and a right surface 412. The top surface 414 is configured to transition between the open configuration shown in FIG. 4 to a closed configuration.

8. The collapsible container of claim 5, wherein the first line segment and the second line segment intersect at a first apex, and wherein the third line segment and the fourth line segment intersect at a second apex.

9. The collapsible container of claim 8, wherein the first set of fold lines on the front surface further comprises:

a fifth line segment extending between the first apex and the second apex.

10. The collapsible container of claim 9, wherein the fifth line segment connects the first apex to the second apex.

11. The collapsible container of claim 1, wherein the first set of fold lines are formed on the front surface by stitching the fold lines on the material that forms the front surface.

12. The collapsible container of claim 1, wherein the first set of fold lines are formed by welding an inner lining of the front surface.

13. The collapsible container of claim 1, wherein the second set of fold lines on the left surface comprises a line segment that extends across the left surface from a left side to a right side of the left surface.

14. The collapsible container of claim 1, wherein the second set of fold lines on the left surface defines third and fourth triangular-shaped regions, wherein the third triangular-shaped region is disposed adjacent the front surface and wherein the fourth triangular-shaped region is disposed adjacent the back surface.

15. The collapsible container of claim 14, wherein a hypotenuse of the third triangular-shaped region is disposed along the front surface, and wherein a hypotenuse of the fourth triangular-shaped region is disposed along the back surface.

16. The collapsible container of claim 1, wherein the second set of fold lines on the left surface comprises:

a sixth line segment and a seventh line segment;

wherein the sixth line segment extends from a bottom, left portion near the back and bottom surfaces to a middle region of the left surface;

wherein the seventh line segment extends from a top, left portion near the back surface and opposite the bottom surface to the middle region of the left surface;

a eighth line segment and an ninth line segment;

wherein the eighth line segment extends from a bottom, right portion near the bottom and front surfaces to the middle region of the left surface; and
