The embodiments described herein relate to shipping containers made of multiple components that can be re-arranged and interconnected into a variety of different sizes.
For many years, industries dealing in bulk goods have utilized returnable shipping containers. The use of the conventional shipping container, however, presents a number of disadvantages to the transportation, shipping, agricultural, retail, and handling industry. In particular, the conventional shipping container is typically created from a single mold and thus often comprises only a single piece of plastic (as a non-limiting example) that is only one defined size and length. This is a significant disadvantage because the conventional shipping container cannot change sizes or lengths to accommodate various types of bulk goods. Rather, industries dealing in bulk goods have to acquire and store numerous conventional shipping containers of various sizes.
Moreover, it is expensive to manufacture the conventional shipping container because the process typically requires an enormous press that is needed to inject the plastic into the mold and compress the material into the desired shape and size. For example, it often costs upwards of $1,000,000 to acquire the machinery necessary to manufacture the conventional shipping container. It is also challenging to manufacture a conventional shipping container that consists of a single, large part because a manufacturer is required to maintain a large inventory of different sized molds. In addition, a single quality issue anywhere in the conventional shipping container has the potential to ruin the entire container.
Accordingly, there is a significant need for a variable length shipping container that can be re-arranged and interconnected into a variety of sizes. Such a shipping container would provide industries dealing in bulk goods with the flexibility to re-arrange shipping containers into any desired size without having to acquire and store a variety of conventional shipping containers. Likewise, a variable length shipping container would be much more affordable and simpler to manufacture because it would require significantly smaller molds and presses to manufacture the different components. Along with other features and advantages outlined herein, the variable length containers within the scope of present embodiments meet these and other needs. In doing so, the variable length container possesses market adaptability because of its versatility to be re-arranged into a variety of configurations based on user's needs. The variable length container is also less burdensome for manufacturers because it is lower risk to manufacture smaller parts. In addition, the variable length container eliminates the problem of manufacturers having to maintain a large inventory of different sized molds. The variable length containers within the scope of present embodiments also provide manufacturers more discrete control over the material properties of the final product because different resins and materials could be used for different components.
A variable length container, sometimes referred to herein as a “shipping container” or “container” for brevity, according to multiple embodiments and alternatives comprises multiple components that can be interconnected and re-arranged to provide the user with an array of shipping container sizes. Current embodiments provide for a variable length container comprising a central member, a pair of intermediate members, a pair of wing members, and a support assembly. In some embodiments, the support assembly consists of a central forkstrap, a pair of end forkstraps, a plurality of horizontal supports, and a pair of runners.
According to present embodiments, the edges of the central member are configured to receive either the pair of wing members, the pair of intermediate members, or other variations as selected by the user. In some embodiments, the edges of the central member include a plurality of teeth and a plurality of receiving notches that engage with the corresponding teeth and receiving notches located on the edges of the wing members or the intermediate members. In some embodiments, the central member further includes receiving slots which are adapted to receive either the ribs of the wing members or the ribs of the intermediate members. Likewise, the intermediate members include ribs to engage the central member and receiving slots adapted to receive the ribs of the wing members.
With respect to the support assembly, the central forkstrap is generally positioned below and parallel to the length of the central member, while the pair of end forkstraps are positioned below and parallel to the length of the wing members. Current embodiments provide for a plurality of horizontal supports that connect the central forkstrap to the pair of end forkstraps via a series of tines and corresponding apertures located at the ends of the horizontal supports. In some embodiments, the horizontal supports and the runners are perpendicular to the central forkstrap and the pair of end forkstraps.
The central forkstrap and the pair of end forkstraps each comprise a middle component, a pair of connectors, and a pair of end components. According to present embodiments, the bottom surface of the central member comprises a plurality of forkstrap receiving bores that are adapted to receive and engage the middle component and end components of the central forkstrap. Likewise, the bottom surface of the pair of wing members comprise a plurality of forkstrap receiving bores adapted to receive the middle component and end components of the pair of end forkstraps. In some embodiments, the variable length container is further secured together by screws and forkstrap connectors.
Current embodiments provide for the central member, the intermediate members, and the wing members each having a plurality of receiving notches to receive the teeth of the sidewalls. As discussed in more detail below, a user can assemble the variable length container by securing the wing members to the central member, then attaching the support assembly to the bottom surface of the wing members and the central member. A user can then attach the sidewalls to complete the assembly. Moreover, in current embodiments the user can vary the length of the shipping container by also incorporating additional wing members, one or more intermediate members, or by selecting wing members of various sizes.
Accordingly, the variable length container in current embodiments affords a versatility of sizes and lengths that provides a key advantage over conventional shipping containers. The components may be easily and quickly re-arranged into a number configurations disclosed herein. Along with other features disclosed herein, the versatility of the variable length container provides a number of advantages over the conventional shipping container.
