The invention relates to a collapsible reusable container. More specifically, the invention relates to a multi-component container, which when disassembled, forms an extremely compact self-contained “kit” which contains all of the components needed to construct a complete container which may be reused indefinitely.
The patent literature contains reference to many examples of containers which are said to be reusable, as well as examples of containers which are said to be collapsible. Many of these containers, upon further inspection, when disassembled, merely result in a collection of many loose components which may become separated, damaged or lost during return transport. The more truly “collapsible” such containers become, the more fragile, and less reusable, they tend to be.
It would, therefore, be desirable to have a container which is easy to assemble, forms a truly self-contained “kit” when disassembled, while at the same time being robust enough to withstand multiple cycles of transport.
The present invention relates to a reusable, collapsible container which, when in a disassembled state is completely contained in an area no larger than the base member thereof, is easy to assemble and due to the interlocking features of a number of the component parts of the container, requires a minimal number of separate locking/fastening devices.
The base member of the container of the present invention serves multiple functions. It functions as a relatively conventional base/pallet when the container is assembled, but serves, unconventionally, as the storage container for all of the remaining component parts of the container. Access openings in the base member preferably allow transport of the container in either the assembled or disassembled state by forklift, or other types of container transport equipment
The interaction of various other components of the present container with the base member is an important aspect of the invention. More specifically, a first horizontal support member, having a plurality of locking tab receiving openings formed in the peripheral area thereof, is disposed in the base member, the first horizontal support member having a shape, generally, corresponding to the shape of the base member. The base member may have any predetermined geometric shape, but is preferably square or rectangular.
Locking tabs are formed in the bottom peripheral portions of vertical wall members in predetermined positions, so as to align with the locking tab receiving openings in the first horizontal support member. The locking tabs of one or more of the vertical wall members are lockingly inserted into the locking tab receiving openings of the first horizontal support member and are thus preferably interlocked for each individual vertical wall member, but are not integrally interlocked as an overall structure.
Such overall, or integral interlocking of one or more of the vertical wall members may be accomplished by placement of the second horizontal support member over the first horizontal support member, and peripherally lockingly contacting one of more of the vertical wall members. Greatly enhanced structural rigidity of the structure of the container results therefrom. “Front-end” loading of the present container is possible in one configuration of the container.
The vertical wall members also have locking device receiving openings formed therein, as does a top member. Locking devices, preferably locking clips are configured so as to fit into locking device receiving openings in adjacent container members, for example the top member and vertical wall member, or two adjacent vertical wall members. Due to the enhanced container rigidity created by the utilization of the locking tabs and the second horizontal support member, the number of locking devices necessary to meet container integrity requirements is minimized.
Methods of assembling the container of the invention are also provided.
Additional objects, advantages and features of the present invention will become apparent from the following description and appended claims taken in conjunction with the accompany drawings in which:
The present invention relates to a compactly storable, easily assembled, reusable container for transporting many different types of cargo.
While the container can be made from any suitable material, apart from certain base reinforcing members, which are preferably made from wood, and locking devices which are preferably made from metal, most of the other components of the container are preferably made from wood composite materials, such as oriented strand board (OSB).
Applicants note at the outset, that while the container of the present invention is formed from a number of components, it is more than just a collection of components in the novel manner in which the components interact when assembled and in the manner in which they neatly and logically self-store when disassembled.
The multi-functional base member 12 of the reusable container 10 is made up of a plurality of base reinforcing members 22 to which are mechanically fastened, by any suitable fastening device, parallel front and rear vertical base members 14, 16 which are separated by a distance substantially equal to the length of parallel first and second vertical side base members 18, 20. First and second vertical side base members 18, 20 are substantially perpendicular to front and rear vertical base members 14, 16, and when mechanically fastened to one another, form the substantially square or rectangular periphery of base member 12. (See
Over the horizontal sub-base member 24, a first horizontal support member 26, having a shape substantially corresponding to that formed by vertical base members 14, 16, 18, 20, is disposed. In the peripheral area of the first horizontal support member 26, a plurality of locking tab receiving openings 30, 130 are formed. (See
Other components of the present container include at least one vertical wall member. Preferably, the container is provided with front and rear vertical wall members 32, 34 and first and second side vertical wall members 36, 38. Each of the vertical wall members has at least one locking tab 40, 140 formed in a bottom peripheral portion of vertical wall members 32, 34, 36, 38. (See
Still another component of the present container is second horizontal support member 44 which is disposed over the first horizontal support member 26. (See
Once vertical wall members 32, 34, 36, 38 are installed as previously described, a top member 50 is brought into closing contact with upper peripheral portions of vertical wall members 32, 34, 36, 38. Preferably, top member 50 (See
Even though all of the previously described components of the reusable container 10 are interlocked with one or more other adjacent components, it will in most instances, be desirable to further increase the structural integrity of the container 10. This is accomplished by utilization of a plurality of locking devices 48, having first and second ends. Typically, such locking devices are substantially L-shaped and are made from a metal having certain spring-like qualities. Preferably, each of vertical wall members 32, 34, 36, and 38, and top member 50 are provided with a plurality of locking device receiving openings 42 in the near-peripheral area of each of the aforementioned components of container 10. By inserting the first end of a locking device 48 into a locking device receiving opening 42 in, for example, front vertical wall member 32, and the second end of the locking device 48 into a locking device receiving opening in, for example, first side vertical wall member 36, these two components are positively interlocked. This process is repeated as necessary to ensure interlocking of component of container 10 as deemed necessary. Due to the interlocking of the components provided in the inventive container apart from the locking devices 48, the number of locking devices needed may be only 50% of the number needed in conventional containers, for example, 50% of 24-32 locking devices.
With this overview, the container of the invention will now be described in more detail with reference to the figures which are a part of this application.
