The present invention relates to the field of storage containers, methods of formation of storage containers, and use of storage containers to ship goods.
Storage containers are used to transport goods across oceans on large ships, and across land on truck beds. In order to ship containers across seas, the containers must conform to the Convention of Safe Containers, which determines the dimensions and load capacities of different containers. Containers of predetermined dimensions are generally loaded into the cell of a ship and stacked one upon another for transport. For example, it is known to provide containers measuring 20 feet in total length and 40 feet in total length for loading into a cell of a ship.
Storage containers are also used to store items at construction sites, homes, and elsewhere, and can be used accordingly upon completion of shipping on ships. Different sizes of storage containers may be desired according to the various applications for which the storage container may be used. For example, containers measuring 10, 16, or 24 feet in length may be desired according to various applications.
It is known to join two containers measuring 10 feet each in length to form the container measuring 20 feet in total length. The container measuring 20 feet in total length may be used during shipping and then separated into two containers measuring 10 feet in length. In this manner, the shipping of cargo using containers can proceed according to the length requirement, and the later use of storage containers can proceed according to the length desired for the particular application.
For a standard 40 foot container, it is known to provide a tunnel extending along a bottom surface of the container. The tunnel allows the 40 foot container to rest on the bed of a chassis, where it can be used to ship cargo over land.
SUMMARYOne embodiment of the present invention includes a storage container having a first container portion approximately 24 feet in length and having a first front portion, and a second container portion approximately 16 feet in length and having a second front portion. The first and second front portions are coupled to form a cargo container approximately 40 feet in length and having an opening extending approximately 40 feet through the storage container. A first panel to cover the first end portion is mounted to the storage container and a second panel to cover the second end portion is mounted to the storage container.
In another embodiment, the first and second front portions are coupled by a joining panel.
In another embodiment, a storage container includes forklift pockets extending laterally near a bottom surface of the storage container. The bottom surface also includes a tunnel extending along a portion of a length of the storage container from a first end of the storage container. The tunnel includes two spaced apart side members extending perpendicular to the fork pockets. At least one opening is provided in at least one of the two side members of the tunnel at an intersection of at least one forklift pocket and the tunnel, the opening configured to allow passage of a fork of a forklift through the forklift pocket into the tunnel.
In another embodiment of the invention, a method of shipping a container includes fixing a first container and a second container together, the first container measuring approximately 24 feet in length and the second container measuring approximately 16 feet in length, to form a completed container measuring approximately 40 feet in length. Front panels are mounted to the first and second containers to permit a through opening of approximately 40 feet in length to extend through the completed container. The completed container is then loaded, shipped and unloaded.
In another embodiment, the method of shipping the container further includes renting the completed container to a shipper for shipping a load and/or selling the first and second containers to one or more parties, and delivering the first and second containers to the one or more parties after shipping the completed container.
BRIEF DESCRIPTION OF THE DRAWINGS
With reference to
The completed container 10 is generally used to ship cargo in a ship across seas. Upon arrival at a shipping destination, the completed container 10 is capable of being separated into the first and second containers 12, 14, as described below. Upon separation from one another, the first and second containers 12, 14 may be used for separate applications. The completed container is generally made of steel of different varieties, but may be made of any suitable material. Anti-corrosive steel or an equivalent is often used to form the completed container 10.
The completed container 10 includes four corner posts 16 (two not seen) extending vertically according to the dimension H along junctions of various panels used to form the completed container 10. The corner posts 16 are formed from rolled high tensile steel, for example. Top side rails 15 and bottom side rails 17 extend horizontally according to the dimension L along junctions of the panels. Corner fittings 18 are located at the top and bottom of the corner posts 16. The corner fittings 18 are formed of casted weldable steel, for example. The corner posts 16 are designed to bear the load of the containers, particularly as the containers are stacked one on top of another in the ship silo or on a loading dock, as is known in the art. The corner posts 16 also provide structural support for lifters which grasp the completed container at the corner fittings 18 and corner posts 16 to stack and/or transport individual completed containers at a loading dock or on a ship, as known in the art. The corner fittings include openings 19 for engagement by the lifters. The corner posts 16 and the rails 15, 17 are welded into the corner fittings 18.
The completed container 10 is formed with panels and doors. Side panels 21 extend between the corner posts 16 along the length L of the completed container 10. The side panels 21 are corrugated in order to provide structural rigidity to the completed container 10. A top panel (not shown) extends along a top surface of the completed container 10 between the top rails 15. A first end 23 and a second end 25 of the completed container 10 each include doors, described in more detail below. The completed container also includes a bottom (not shown) extending between the bottom rails 17. The side panels 21, top panel, bottom and doors located at the first and second ends 23, 25 together define an inside area of the completed container.
The first container 12 is 24 feet in length according to a dimension L1, and can be separated from the second container 14, as described below. The length L1 of the separated first container 12 is beneficial for use on the bed of transport trucks, as well as for storage applications involving pipe, which often measures approximately 24 feet. The second container 14 is approximately 16 feet in length according to a dimension L2. The length L2 of the separated second container 14 is particularly beneficial for use in storage applications where a 10 foot container is too small and a 20 foot container is too long. The first or second container 12 or 14 may also be placed on flat rail cars and secured by twistlocks at the bottom corner fittings of the first or second container. The first and second containers may be used in a variety of applications, and may remain permanently attached to one another, according to the application for which the completed container 10 is to be used. It will also be appreciated that other length containers may be used to form a 40 foot container, such as a 25 foot first container and a 15 foot second container.
The first and second containers 12, 14 are joined at a junction point 26 of the completed container 10. At the junction point 26, the first and second containers each include a front end 27. The front ends 27 of the first and second containers 12, 14 include corner posts 28, similar to the corner posts 16 in form and function, and corner fittings 29, similar to the corner fittings 18. The front ends 27 are joined together by a joining apparatus 31, as described below, to form the completed container 10. When detached from each other, the front ends 27 of the first and second containers 12, 14 may be provided with front panels (not shown) attached thereto, as described below. With the front panels attached to the front ends 27, the first and second containers 12, 14 are used for their respective applications, as described above.
The first and second containers 12, 14 are lifted using forklift pockets 20 located along a lower edge of the containers, near a surface on which the containers rest. The forklift pockets, explained in greater detail below, extend laterally along a bottom of the containers 12, 14, and are spaced along the lengths L1 and L2 to allow for engagement with a fork lift, which lifts the first or second container as known in the art.
