## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to household products and specifically to a collapsible container and a method of making and using such a container for convenient storage and transportation of said products.
A typical household often encounters the need for temporary storage of garments prior to washing or cleaning. Regardless of the place where laundry or cleaning is done, either at home or in a commercial setting, soiled garments need to be sorted, stored, and eventually transported to a designated place. The present invention can be utilized for garment sorting, storage and transportation. At the same time, the present invention can also be used for other purposes, such as storage or transportation of toys or other objects. Accordingly, its use is not to be limited to storage or transportation of soiled garments.
Numerous devices are known in the art to provide effective storage of soiled garments, for example laundry baskets, conventional hampers, or clothing bags. For example, U.S. Pat. No. 2,625,973 to Weldon et al. teaches a laundry hamper comprising a rectangular frame having upper and lower portions that telescope within one another in a detachable manner. The lower portion includes a base frame, while the upper portion comprises a top frame. A cover is secured by a hinge to the top frame and an outer bag surrounds the rectangular frame. A plurality of small inner bags are provided within the outer bag. U.S. Pat. No. 1,581,888 to Thomas discloses a collapsible receptacle comprising two rectangular wire frames, hingedly secured together, means for holding the frames to form a triangularly shaped structure, and a fabric portion covering the frames and providing an enclosure. However, all these prior art devices are voluminous in their expanded state, are uneasy to fold or collapse, are still relatively voluminous in their collapsed state, and are difficult to manipulate.
The present invention solves the above-mentioned shortcomings and provides a convenient, easy to manipulate, and ergonomic means for storing or transporting garments or other objects.
SUMMARY OF THE INVENTION
A collapsible container according to the present invention includes a plurality of adjacent side panels, preferably four, each of which include a continuous, non-interrupted, planar web having a perimeter, and a frame member coupled to at least a portion of the perimeter. At least one of the panel frame members forms a discontinuous loop. Each of the side panels has a bottom side, a top side and two lateral sides, and is preferably generally rectangular in shape. The container further includes a floor panel having a plurality of sides, each of the sides being coupled to at least one side panel bottom side. Each of the lateral sides of each side panel is coupled to a lateral side of an adjacent side panel. One of the frame members forming a discontinuous loop may be a unitary member, or may comprise a plurality of members, perhaps two or three.
An embodiment of a collapsible container according to the present invention may provide each of the panel frames forming a discontinuous loop. In such a case, each frame may comprise a single, unitary member or a plurality of frame members, perhaps two or three.
An embodiment of a collapsible container according to the present invention may include at least one handle member, which is coupled to at least one of the side panels. Rather than being coupled to a side panel, a handle member may be formed by the formation of at least one aperture being formed at least partially within at least one side panel.
An embodiment of a collapsible container according to the present invention may include a storage pouch, which is coupled to one of said side panels, preferably near the open top of the container.
An embodiment of a collapsible container according to the present invention may include a flexible frame for each of said side panels.
An embodiment of a collapsible container according to the present invention may include a plurality of adjacent side panels. Each of the side panels may include a web having a perimeter, an edging attached to at least a portion of the perimeter of the web and forming a frame pocket, and a frame positioned at least partially within the frame pocket.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structures. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
Prior advancements in collapsible containers have been made, for example, in U.S. Pat. No. RE37,924. Despite these prior advancements, all such prior containers utilize a continuous loop structure to frame a given flexible panel. While such structure may be desirable for some applications, it may be desirable in other applications to reduce the amount of framing material required to construct a collapsible container.
An embodiment 10 of a collapsible container according to the present invention is illustrated in FIGS. 1 through 6.
As shown in FIG. 4, the container 10 comprises a plurality of side panels 20 and a floor panel 50. The side panels 20, of which there are preferably four, may be of any desirable shape, but are preferably generally rectangular. The container 10 may further include two handles 60 and 62. The side and floor panels 20 and 50 are coupled to one another to form a generally parallelepiped container having an open top 16.
Referring to FIGS. 1 and 2, and as seen in detail in FIG. 5, each side panel 20 further comprises a frame 22, a web 24, and an edging 26. The frame 22 is flexible, preferably formed from a sufficiently stiff yet resilient material such as spring steel wire or plastic, and is contained within a channel or pocket 25 formed by the edging 26. The frame 22 of at least one panel 20 forms a non-continuous loop. Preferably, the frame 22 has a rectangular cross-section, but a material with a different geometric cross-section can be used. The web 24 is a flexible foldable material, such as nylon cloth or nylon mesh, but can be any suitably flexible material. The web 24 may be solid or perforated. The perimeter of the web 24 is coupled to the edging 26 such that the edging 26 forms a pocket 25 about the periphery of the web 24. The edging 26 is a foldable, preferably stretch-resistant material capable of housing the frame 22 within its pocket 25. The edging 26 has two ends 27 and 29. While the edging 26 is shown to be a separate component coupled to the web 24, the edging 26 may also simply be an extension of the web 24 having been folded upon itself to form the pocket 25. Pocket caps 28, also made out of a foldable stretch-resistant material, may be provided to cover the ends 27 and 29 of the edging 26, thereby protecting the frame 22 from escaping out of the edging 26. Each pocket cap 28 is preferably spaced from each other pocket cap 28 used on a given panel 20, thereby leaving at least one frameless section 31 on the panel 20, thereby reducing the amount of framing material required.
As can best be seen in FIG. 24, the floor panel 50 is also a foldable web of material and has a generally rectangular shape. The floor panel 50 has a plurality of coupling tabs 52 and a plurality of panel interface sections 54, which may be separated by the coupling tabs 52. The floor panel 50 may have the same number of coupling tabs 52 as the number of panels 20 forming the sides of the container 10. Each coupling tab 52 is adapted to be directly or indirectly coupled to two adjacent side panels 20, and each panel interface section 54 is adapted to be directly or indirectly coupled to one or more side panels 20. The floor panel 50 provides means for holding the garments or other objects (not shown) within the container 10 and for supporting the container 10 in its expanded state.
Returning to FIG. 2, each side panel 20 includes a top side 32 corresponding to the open top 16 of the container 10, a floor side 34 coupled to one of the panel interface sections 54 of the floor panel 50, and two lateral sides 36 and 38. Each lateral side 36 and 38 is directly or indirectly coupled to a corresponding lateral side 38 or 36 of an adjacent side panel 20.
As depicted with respect to the first embodiment 10, the handles 60 and 62 have both ends connected to the top side 32 of two opposing side panels 20. The handles 60 and 62 are formed from a preferably stretch-resistant material having a mesh web that extends between a portion of each strap side. The handles for the present invention are not limited to such particular type. Several alternate embodiments are shown in FIGS. 7 through 10, illustrating different handle members. In FIG. 7, the handle members 60 and 62 are straps stitched to opposite side panels 20. FIG. 8 depicts an alternate embodiment wherein the handle members 60 and 62 are apertures or openings formed in the webs 24 of two opposite side panels 20. In FIG. 9, one handle member 60 is shown as a strap coupled to diagonally opposed seams between adjacent side panels. In FIG. 10, the handles 60 and 62 are preferably stitched directly to the webs 24 of two opposite side panels 20.
As shown in FIG. 11, a sixth embodiment of a collapsible container according to the present invention may include an optional storage pouch 70, which may be formed from a foldable material, such as nylon mesh, and coupled to one of the side panels 20. The storage pouch 70 may be dimensioned to accommodate the container 10 in its collapsed state as later described.
Although stitching is presented as the preferred means for directly coupling the elements of the container 10 and permitting relatively convenient folding of the container 10, it is to be understood that other methods can be used for directly coupling components in an embodiment of this invention. Such methods may include heat sealing, gluing and the like. Accordingly, construction of the collapsible container should not be limited to stitching alone.
FIGS. 12 through 15 depict a seventh embodiment 12 of a collapsible container according to the present invention. The container 12 further includes a divider panel 80. The divider panel 80 is coupled preferably to opposing portions of the container 12, thereby dividing the interior of the container 12 into two chambers.
FIGS. 16 to 19 show an eighth embodiment 14 of a collapsible container according to the present invention. The container 14 comprises six side panels 20 and two divider panels 80 and 82. The divider panels 80 and 82 are arranged preferably substantially parallel to one another. Each divider panel 80 and 82 is made out of a foldable material, such as nylon mesh, and has two sides 86 and 88 stitched to webs 24 of two opposite side panels 20. The divider panels 80 and 82 separate the interior of the container 14 into three compartments for improved sorting and storage of objects.
FIGS. 20A to 26 show various stages in the manufacturing process of the preferred embodiment of collapsible container 10. Referring to FIGS. 20A and 20B, the step of stitching the handle 60 to the top side 32 of a web 24 is shown. Specifically, the stitching is shown at 90. A second handle 62 may be coupled to a second web 24.
In FIG. 21, a pocket cap 28 is partially stitched to a side 21 of each of the plurality of webs 24. Each pocket cap 28 is preferably spaced from each other pocket cap 28 used on a given panel 20. The preferred aggregate spacing 31 between the caps 28, or length without having a frame member 22 located along a given side of a panel, may be as little as fifteen percent, or less, of the height of the panel 20 or as much as forty percent of the height of the panel 20, thereby reducing the amount of material required for the frame 22. As an example, a given side panel 20 having a height to width ratio of 2:1 would thus experience a decrease in frame material requirements over prior devices by about ten percent to about twenty-five percent or more. The edging 26 is then folded in a channel-like fashion around the periphery of the web 24 and stitched to the web 24. The stitched edging 26 forms a pocket 25 along at least a portion of the periphery of each web 24. In the preferred embodiment, the container 10 utilizes four panels 20. An example of a non-handled panel 20 is shown in FIG. 22, and an example of a panel 20 including the handle 60 is shown in FIG. 23.
Generally, after the desired plurality of panels 20 has been formed, the next step involves coupling the floor panel 50 to each of the side panels 20. The two side panels 20 containing the handles 60 and 62 should be positioned opposite each other with the handles 60 and 62 facing inwardly toward each other. First, the floor side 34 of each of the side panels 20 is stitched to one of the panel interface sections 54 of the floor panel 50. Next the lower portions of the lateral sides 36,38 of each of the side panels 20 is stitched to the coupling tabs 52 of the floor panel 50. The remaining portions of the lateral sides 36,38 are then coupled to corresponding adjacent side panel lateral sides 38,36, respectively.
The final steps of the manufacturing process of a collapsible container according to the present invention involve inserting the frame 22 into each panel pocket 25 formed by each of the edgings 26 as shown in FIG. 26. The frame 22 is passed through the edging 26 and around at least a portion of the periphery of each of the side panels 20. Finally, any open pocket caps 28 are stitched or otherwise closed, thereby protecting the frame 22 from escaping the edgings 26.
From the expanded state, the container 10 may be folded into a collapsed state for storage and transportation. FIGS. 27 to 32 show various steps for collapsing the container 10. Referring to FIG. 27, the first step requires grasping opposite sides of the container 10 and biasing one toward the other until all side panels 20 are adjacent and overlay each other. The next step includes inserting the handle members 60 and 62 and the floor panel 50 in between any two of the adjacent overlaying side panels 20 is shown in FIG. 28. If a storage pouch 70 is provided, it is important to make sure that the storage pouch 70 remains outside of the collapsed side panels 20. In the preferred embodiment, the resulting partially collapsed container 10 is a stack of four side panels 20. FIGS. 29 and 30 show the next step of rotating two opposite corners 101 and 103 of the partially collapsed container 10 in opposite directions while biasing the corners 101, 103 toward each other. The container 10 will first twist and then will rotate to form three overlaying circular loops 150 situated adjacently as shown in FIG. 31. The final step, shown in FIG. 32, is the insertion of the collapsed container 10 into the storage pouch 70.
When the collapsed container 10 is removed from the storage pouch 70, the frame members 22 will bias the panels 20 into their fully expanded state. Again, the fully expanded state of the preferred embodiment is that shown in FIG. 4.
FIG. 33 provides a partially assembled eighth embodiment 13 of a collapsible container according to the present invention. Generally, this embodiment 13 includes a plurality of panels 20, including at least one frame 22 being discontinuous and divided into two panel support members, each panel support member being within a pocket formed by the edging 26 of the panel 20 and being located between two pocket caps 28.
FIG. 34 provides a partially assembled eighth embodiment 15 of a collapsible container according to the present invention. Generally, this embodiment 15 includes a plurality of panels 20, including at least one frame 22 being discontinuous and divided into three panel support members, each panel support member being within a pocket formed by the edging 26 of the panel 20 and being located between two pocket caps 28.
The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
