Description




BACKGROUND OF THE INVENTION




The present invention relates generally to household products and specifically to a collapsible container with handles and a method of making and using such a container for convenient storage and transportation of said items.




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




The present invention relates generally to household products and specifically to a collapsible container and method of making and using the same.




According to the present invention, the foregoing and other advantages are obtained by providing a collapsible container comprising a plurality of side panels and a floor panel forming an enclosure having an open top. In the preferred embodiment, each side panel comprises a flexible continuous loop frame, a web of material, and an edging material. The edging envelops the frame and is coupled to the periphery of the web. The floor panel is attached to the bottom side of each side panel thus forming the container.




In an alternate embodiment, each side panel is attached to a side panel separator, which in turn is connected to the next adjacent side panel. The floor panel is attached to both the bottom side of each side panel and to the side panel separators, thus providing means for holding articles within the container and for supporting the container in its expanded state.




In accordance with an aspect of the invention, at least one handle member is coupled to opposite side panels at the open top of the container. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels.




In accordance with another aspect of the invention, an optional storage pouch may be coupled to one of the side panels at the open top of the container. The present invention is easily collapsed into a compact state and the pouch allows storage of the container in its collapsed, compact state.




In another alternate embodiment, the collapsible container further comprises a divider panel, the divided panel being attached to diagonally opposite edgings of the side panels. In yet another alternate embodiment, the collapsible container further comprises at least two divider panels, preferably arranged substantially parallel to each other and being coupled to opposite side panels to create at least three separate compartments within the container.




A preferred method of manufacturing the collapsible container includes the steps of attaching each handle member to a side of two opposite webs. The edging is next coupled to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each side of the floor panel is attached to the bottom side of each side panel. Next, a side of each side panel is connected with a side of an adjacent side panel. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible container its ability to freely stand in a rigid, expanded, upright state.




An alternate method of manufacturing the collapsible container includes the steps of attaching each handle member to a side of two opposite webs. Coupling the edging to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each corner of the floor panel is attached to one end of each side panel separator. Next each side panel is connected with one side of the floor panel and with two adjacent side panel separators. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible container its ability to freely stand in a rigid, expanded, upright state.




From the expanded state, the container can be folded and collapsed for storage or transportation. The preferred steps of collapsing the container include grasping opposite corners of the floor panel and biasing one corner toward the other until all side panels are adjacent and overlay each other. The container is now partially collapsed but each side panel is still in an expanded state. Next, the handle members and the floor panel are inserted in between any two of the adjacent overlaying side panels. By rotating two opposite corners of the flattened, overlaying side panels in opposite directions while biasing the two corners toward each other, the structure will form three overlaying circular loops folded adjacently. Finally, the three overlaying loops are placed into the storage pouch. The pouch prevents the container from springing back into its fully expanded condition.

forms a 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 nylon, or other flexible material, may be solid or perforated. The perimeter of the web


24


is stitched 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, but stretch-resistant material capable of housing the frame


22


within its pocket


25


. The edging


26


has two ends

. Referring just to

FIG. 6A

, each lateral side


36


and


38


is attached to a side panel separator


40


adjacent to the side panel


20


.




As depicted in

FIGS. 4 and 8

, 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 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 the particular type shown in

FIGS. 4 and 8

. Several alternate embodiments are shown in

FIGS. 9 through 12

, illustrating different handle members. In

FIG. 9

, the handle members


60


and


62


are straps stitched to opposite side panels.

FIG. 10

depicts an alternate embodiment wherein the handle members


60

70


is dimensioned to accommodate the container


10


in its collapsed state as later described.




Although stitching is presented as the preferred means for attaching or connecting the elements of the container


10


and permitting relatively convenient folding of the container


10


, it is to be understood that other methods of attachment can be used in this invention. Such of methods may include heat sealing, gluing and the like. Accordingly, construction of the collapsible container should not be limited to stitching alone.





FIGS. 14 through 17

depict an alternative embodiment of the collapsible container


12


. The container


12


further includes a divider panel


80


. Divider panel


80


is connected to opposite side seam separators


40


thereby dividing the interior of the container


12


into two separate chambers.





FIGS. 18

to


21


show a second alternate embodiment of the collapsible container


14


. The container


14


comprises six side panels


20


and two divider panels


80


and


82


. The divider panels


80


and


82


are arranged 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 separate compartments for improved sorting and storage of objects.





FIGS. 22

to


30


show various stages in the manufacturing process of the preferred embodiment of collapsible container


10


. Referring to

FIGS. 22A and 22B

, the step of stitching the handle


60


to the top side


32


of two (2) of the webs


24


is shown. Specifically, the stitching is shown at


90


.




In

FIG. 23

, a seam cover


28


is partially stitched to side


21


of each of the four (4) webs


24


. In the two (2) webs having handles


60


or


62


, the seam cover


28


is placed and sewn opposite to the handle


60


or


62


. Each seam cover


28


is preferably placed in the middle of the side


21


and includes a flap or unstitched portion, but it is to be understood that it could be placed anywhere on any side of each of the webs


24


. Referring now to

FIG. 24B

, the edging


26


is then folded in a channel-like fashion around the periphery of the web


24


and stitched to the web


24


, surrounding the perimeter of the web


24


. The stitching is shown at


28


. The stitched edging


26


forms a pocket


25


around the periphery of each web


24


. In the preferred embodiment, each container


10


requires four (4) webs


20


. The two (2) sides including the web


24


, edging


26


and seam cover


28


are shown in FIG.


20


and the two (2) sides including the handle


60


, web


24


, edging


26


and seam cover


28


are shown in FIG.


25


. Stitching of each edging


26


starts and ends at the seam cover


28


, thereby leaving a small space between ends


27


and


29


of each edging


26


.




In

FIGS. 26A and 26B

, the next step involves stitching each corner section


52


,


54


,


56


,


58


of the floor panel


50


to the end


42


of each side panel separator


40


. The stitching is shown at


46


. Now referring to

FIGS. 27 and 28

, the step of attaching each of the four side panels


20


by means of stitching to the floor panel


50


and the side panel separators


40


is shown. The two (2) 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 sides


51


,


53


,


55


,


57


of the floor panel


50


as shown in FIG.


23


. Still referring to

FIG. 23

, next the lateral sides


36


of each of the side panels


20


is stitched to the corresponding adjacent side panel separator


40


. As shown in

FIG. 28

, once the first lateral side


36


of a side panel separator


40


is stitched on one side, the second lateral side


38


of another side panel separator


40


is stitched to the other side. The resulting enclosure


90


is shown in FIG.


29


.




As discussed previously, the container


10


may be constructed without the side panel separators


20


. In constructing the embodiment without side panel separators, the two (2) side panels


20


containing the handles


60


and


62


are positioned opposite each other with their handles


60


and


62


facing inwardly toward each other. The floor side


34


of each of the side panels


20


is stitched to one of the sides


51


,


53


,


55


,


57


of the floor panel


50


. Next the lateral sides


36


of each of the side panels


20


are stitched to an adjacent side panel


20


thus forming the container


10


having an open top


16


.




The final steps of the manufacturing process of the present invention involve inserting the frame


22


in one of the open ends


27


or


29


of each of the edgings


26


as shown in FIG.


30


. The frame


22


is passed through the edging


26


and around the periphery of each of the side panels


20


. The ends of the frame


22


are joined together such that the frame


22


forms a continuous loop. In the preferred embodiment, the frame ends are connected by inserting each end into a butt connector and crimping the connector. Finally, the unstitched portion of each seam cover


28


is stitched to side


21


of each web


24


and over the ends


27


and


29


of each edging


26


, 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. 31

to


36


show various steps for collapsing the container


10


. Referring to

FIG. 31

, 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.


32


. 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. 33 and 34

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.


35


. The final step, shown in

FIG. 36

, 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 container


10


into its fully expanded state. Again, the fully expanded state of the preferred embodiment is that shown in FIG.

.




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.
