Definitions
- the present invention is directed to an extended length bulk bin having a first plastic bulk bin end piece and a second plastic bulk bin end piece separated by two metal rails supporting a bottom panel, a first side wall panel and a second side wall panel.
- the North-American automotive and most other industrial manufacturing industries have standardized on mainly two footprints for large collapsible containers that are predominantly made with recyclable plastic materials (e.g., plastic bulk bins).
- the present applicant offers three extended length bulk families with footprints of 48" x 56.5", 48" x 62.5", 48" x 64.5", 48" x 70", and 48" x 77.6".
- Containers are offered in standard heights of 25", 34", 42", and 50".
- At least one other company, Buckhorn also sells 48" x 56.5", 48" x 62.5", 48" x 64.5" and 48" x 70" footprints.
- the overseas markets have fundamentally similar systems, but have standardized on different footprints (e.g., 1000mm x 1200mm or 800mm x 1200mm in Europe).
- the present invention provides an extended length bulk bin that can overcome some or all of the problems associated with prior bins.
- the present invention is directed to a flexible and collapsible extended-length bulk bin that uses plastic molded parts for the short-side ends of the container and a combination of standardized metal and sheet material for the internal parts that connect the two ends.
- This construction concept requires a relatively small capital investment for plastic injection molds (since the plastic parts are the same for all lengths), can very easily be adjusted to make containers of a very specific length, and keeps the part costs low compared to custom-designed containers.
- the present concept allows for relatively short lead times (when an order for production comes in) because relatively few components need to be inventoried.
- a collapsible bulk bin family in which each family member consists of two identical plastic molded "book-ends" that form the short-side ends of the bulk bin, is provided.
- Each of these ends contain one short-side sidewall with an access door, a section of the base with an integrated runner, and two corner elements with integrated hinges for the long-side walls.

- The North-American automotive and most other industrial manufacturing industries have standardized on mainly two footprints for large collapsible containers that are predominantly made with recyclable plastic materials (e.g., plastic bulk bins). The smaller footprint measures 32" x 30", and the larger footprint measures 48" x 45" (or sometimes 48" x 44.5"). These footprints are sized to efficiently fill standard truck trailers, most commonly 53-foot trailers.
- For parts that are too large to fit a standard 48" x 45" container (for example bumpers, exhausts, trim parts, hoses, wire harnesses, etc.) a few companies offer plastic extended-length bulk containers, which keep the 48" width of the standard containers (since two 48" widths fit next to each other in a standard trailer), but offer more loading length compared to a standard (i.e., 45") bin.
- The present applicant offers three extended length bulk families with footprints of 48" x 56.5", 48" x 62.5", 48" x 64.5", 48" x 70", and 48" x 77.6". Containers are offered in standard heights of 25", 34", 42", and 50". At least one other company, Buckhorn, also sells 48" x 56.5", 48" x 62.5", 48" x 64.5" and 48" x 70" footprints. The overseas markets have fundamentally similar systems, but have standardized on different footprints (e.g., 1000mm x 1200mm or 800mm x 1200mm in Europe).
- It is apparent that the larger the container is, then fewer containers fit per standard trailer or truck. This increases the shipment cost per container. Therefore, the need to have a container that fits the shipped product as close as possible without giving away extra space grows with the size of the container, especially because most of the large parts that are shipped in plastic extended-length containers are relatively light and typically do not "weigh out a trailer" (meaning that a trailer can be completely filled with the same product without exceeding the allowable loaded weight of the trailer).
- While the fixed-footprint plastic extended-length bulk bins mentioned above are relatively cost-efficient to produce, it is of course possible and common practice to custom-manufacture extended-length containers from various materials (for example plastic, wood, steel, or a combination thereof) for a specific application. However, these custom containers tend to be very expensive and are often difficult to recycle.
- There are several reasons why dedicated plastic extended-length collapsible bulk bins are not offered in more sizes and/or by more manufacturers: (1) the required investment in tooling (e.g., injection molds) is very high due to the size of the parts; (2) individual component weights are very high and require very large molding presses (i.e., most often the bases and long side panels exceed the available shot weights of high-pressure molding machines and require structural-foam technology); and (3) the larger the container the more difficult it is to handle with fork lifts (e.g., move, stack, de-stack), which makes it more susceptible to damage, especially if the container is made from plastic (a few automotive customers have switched back to steel containers and racks because of this problem).
- The present invention provides an extended length bulk bin that can overcome some or all of the problems associated with prior bins.
- The present invention is directed to a flexible and collapsible extended-length bulk bin that uses plastic molded parts for the short-side ends of the container and a combination of standardized metal and sheet material for the internal parts that connect the two ends. This construction concept requires a relatively small capital investment for plastic injection molds (since the plastic parts are the same for all lengths), can very easily be adjusted to make containers of a very specific length, and keeps the part costs low compared to custom-designed containers. Furthermore, the present concept allows for relatively short lead times (when an order for production comes in) because relatively few components need to be inventoried.
- In accordance with one aspect of the invention, a collapsible bulk bin family, in which each family member consists of two identical plastic molded "book-ends" that form the short-side ends of the bulk bin, is provided. Each of these ends contain one short-side sidewall with an access door, a section of the base with an integrated runner, and two corner elements with integrated hinges for the long-side walls. The two end-pieces are connected with fabricated elements forming part of the base deck and parts (i.e., segments) of the long-side sidewalls.
- Having identical ends reduces the tooling cost that is required (with single-cavity molds, two press hits are required to produce the plastic parts for one bulk bin). Moreover, incorporating as many functional features as possible into the plastic parts (e.g., all sidewall and door latches; all sidewall hinges, molded-in logos and graphics) simplifies the construction of the fabricated center section and helps to reduce part costs.
- In accordance with another aspect of the invention, a flexible extended-length bulk bin is provided comprising a first plastic molded end piece and a second plastic molded end piece. The bin further comprises a first rail extending from a first side of the first plastic molded end piece to the first side of the second plastic molded end piece and a second rail extending from a second side of the first plastic molded end piece to the second side of the second plastic molded end piece. A first bottom panel extends between the first rail and the second rail.
- The first rail and the second rail can be metal. Also, a first cross brace can extend between the first rail and the second rail. A second cross brace (or more) can also extend between the first rail and the second rail spaced from the first cross brace. Having cross braces accommodates having a second bottom panel extending between the first rail and the second rail; and possibly a third bottom panel (or more depending on the number of cross-braces) extending between the first rail and the second rail. The bottom panels can be plastic or a wire mesh, or other similar or suitable materials.
- The first plastic molded end piece can include an access door hingedly connected to an end wall of the first molded end piece. Similarly, the second plastic molded piece can include an access door hingedly connected to an end wall of the second molded end piece. In fact, the first and second plastic molded end pieces can be identical.
- The extended-length bulk bin can further comprise a first side panel extending upward from the first rail between the first plastic molded end piece and the second molded end piece. Similarly, the flexible extended-length bulk bin can also include a second side panel extending upward from the second rail between the first plastic molded end piece and the second molded end piece.
- The first side panel can include a solid plastic sheet. Alternatively, the first side panel can include a wire mesh. The panel can further include other similar or suitable materials.
- The first and second plastic molded pieces can each include a plurality of downwardly extending feet. Also, a plastic molded runner and/or a metal sheet can extend between the feet on each piece.
- The first plastic molded piece can include a first side wall segment on the first side and a second side wall segment on the second side, and the second plastic molded piece can also include a first side wall segment on the first side and a second side wall segment on the second side. The first side wall segment of the first plastic molded end piece can be hingedly attached to the first plastic molded end piece and the second side wall segment of the first plastic molded end piece can be is hingedly attached to the first plastic molded piece. Similarly, the first side wall segment of the second plastic molded end piece can be hingedly attached to the second plastic molded end piece and the second side wall segment of the second plastic molded end piece can be hingedly attached to the second plastic molded end piece.
- In accordance with yet another aspect of the invention, a flexible extended-length bulk bin comprises a first plastic bulk bin end piece having a bottom segment, an end wall extending upward from the bottom segment, a first side wall segment hingedly connected to and extending upward from a first side of the bottom segment, a second side wall segment hingedly connected to and extending upward from a second side of the bottom segment. The bin also comprises a second plastic bulk bin end piece having a bottom segment, an end wall extending upward from the bottom segment, a first side wall segment hingedly connected to and extending upward from a first side of the bottom segment, a second side wall segment hingedly connected to and extending upward from a second side of the bottom segment. The bin further includes a first metal rail extending from the first side of the bottom segment of the first plastic bulk bin end piece to the first side of the bottom segment of the second bulk bin end piece, and a second metal rail extending from the second side of the bottom segment of the first plastic bulk bin end piece to the second side of the bottom segment of the second bulk bin end piece. A first bottom panel extends between the first metal rail and the second metal rail. A first side wall panel extends between the first side wall segment of the first plastic bulk bin end piece and the first side wall segment of the second plastic bulk bin end piece, and a second side wall panel extends between the second side wall segment of the first plastic bulk bin end piece and the second side wall segment of the second plastic bulk bin end piece. The end wall of the first plastic bulk bin end piece can include a hinged access door.
