Collapsible storage bin with attached lower pallet-like support
A collapsible bin for the storage and transport of goods, which includes a collapsible sidewall structure and upper and lower pallet-like supports. A securing structure secures the sidewall structure to the lower pallet-like support while permitting the sidewall structure to be placed in either a collapsed or non-collapsed state. The first and second pallet-like supports each include a base and a border that projects out from and runs along an edge of the respective base. A portion of the border located at each corner of the base of each pallet-like support is notched out, allowing the first and second pallet-like supports to cooperate with and nest within each other when the storage bin is placed in a collapsed state.
This application claims priority under 35 USC §119(e) of copending provisional application Ser. No. 60/534,868 filed Jan. 8, 2004, the entire disclosure of which is herein incorporated by reference.
FIELD OF THE INVENTIONThis invention relates to an improved collapsible sidewall structure which cooperates with upper and lower supports, such as pallets, to define a stackable storage bin.
BACKGROUND OF THE INVENTION U.S. Pat. No. 4,700,862, as owned by the Assignee hereof, illustrates therein a stackable bin which has met with significant commercial success, and which has proven highly desirable for permitting storage of product therein in such a fashion as to permit shipment between locations, and storage at a selected location. This type of stackable bin, as illustrated in
After transportation and removal of the goods, the empty storage bin is folded down into a compact unit that facilitates return shipment of the empty bin while occupying only minimal space. In order to fold down a traditional bin, such as that described above, the upper and lower pallet-like supports are first removed from the four-sided wall structure. The four-sided wall structure is then folded down into a compact unit as shown in
To further reduce the amount of space taken up by three separate pieces of a collapsed bin of the above type, another type of storage bin includes box-shaped upper and lower pallets, wherein the collapsed wall structure can be placed inside one of the pallet-like supports. The remaining pallet-like support is then placed on top of the other support, thereby forming a relatively compact container made up of the two pallet-like supports and containing the collapsed wall structure. However, this specific stacking arrangement including the above three separate pieces is not always carried out by the person or persons responsible for collapsing the bin and getting same ready for return shipment. As such, the collapsed bin may take up more room than is actually necessary due to improper disassembly. Furthermore, as the pallet-like supports are removable from the four-sided wall structure, there is always the possibility that one of the pallet-like supports will be separated from the arrangement or lost. Lastly, upon setting up the bin for its reuse as a storage container, the removable wall structure must first be appropriately positioned with respect to the lower pallet-like support before loading of the storage bin can commence. Yet, positioning the removable wall structure relative to the lower pallet-like support can be difficult for an individual person to accomplish due to the relatively large and awkward size of the wall structure and pallet-like supports.
In addition to the issues presented above, traditional collapsible storage bins are also frequently subject to damage due to their use of top and bottom pallet-like supports of differing dimensions. Specifically, one pallet-like support is often made larger than the other so that when the storage bin is placed in a collapsed state, one pallet-like support will fit or nest inside the other when stacked. However, when the collapsible bin is expanded so that it may be used for the storage and transport of goods, the larger of the pallet-like supports tends to extend outwardly a significant distance beyond the boundaries of the rest of the storage bin (i.e. the opposite pallet-like support and upright wall structure) and subsequently be subject to damage by the equipment used to transport the storage bins. In response, the Applicant has developed a new and improved collapsible bin that addresses the problems raised above.
The present invention relates to an improved collapsible bin for the storage and transport of goods. The collapsible storage bin comprises a collapsible sidewall structure and upper and lower pallet-like supports. Further included is a securing structure that secures the sidewall structure to one of the pallet-like supports while permitting the sidewall structure to be placed in either a collapsed or non-collapsed state.
Further, the upper and lower pallet-like supports each include a base and a border or lip that projects transversely from the base and extends along an edge thereof. A portion of the border located at each corner of the respective base is notched out, allowing the opposed pallet-like supports to cooperate with and nest within each other when the storage bin is placed in a collapsed state.

Turning now to the instant invention,
The securing device 30 is also illustrated in
Upon the end walls 22-1 completely folding in, the sidewall structure 13-1 is considered to be in its collapsed or flat state. As illustrated in the cross-sectional perspective view of
Illustrated in
In the above embodiment of the present invention, flange 32 of the securing structure 30 is attached to the interior-facing surface of one of the sidewalls 21-1. However, according to an alternative embodiment, the flange 32 may be attached to the exterior-facing surface of the same sidewall 21-1. Accordingly, when the sidewall structure 13-1 is collapsed and folded down, the ends of both sidewalls 21-1 and end wall layers 26-1 and 27-1 will be covered by the securing structure 30.
In the exemplary embodiment discussed above, and in the associated illustrations, two hinges 36A and 36B are defined on the securing structure 30. However, according to a further embodiment of the present invention, securing structure 30 may possess more than two hinges. For example, in one embodiment (not depicted), the securing structure has three hinges lying between the first and second flanges 32 and 34, thereby providing it with greater flexibility during handling.

Upon expanding the collapsible bin illustrated in
To prevent or at least minimize the damage described above, the top and bottom pallets 28 and 29 of the storage bin 10-1 according to the invention have substantially equal dimensions, but allow the storage bin to continue to be collapsed into the smallest amount of space as is possible. In this regard, the storage bin 10-1 utilizes two substantially identical pallets 28 and 29 for enclosing both the top and bottom openings of sidewall structure 13-1. Since pallets 28 and 29 are substantially identical to one another, only one of same will be described herein. Pallet 28, as illustrated in
The use and operation of the sidewall structure 13-1 of this invention, and in particular its use in association with the structure of the bin 10-1, is believed readily apparent from the description set forth above, particularly when taken in conjunction with

According to an additional embodiment of the present invention (not depicted), any one or more of the sidewalls 21-1 and end walls 22-1 of the sidewall structure 13-1 can be provided with a removable or tear-away access panel so as to provide an access opening to allow double stacking of bins along an assembly line. This access panel can be formed by either cuts or score lines, and the panel can be replaceable such as by being taped in position. The panel and the access opening will be defined wholly within the borders of the respective end or sidewall.
