ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a collapsible container for shipping articles, e.g. windshields, and, more particularly, to a collapsible container for shipping windshields that has walk-in base.
DISCUSSION OF THE TECHNICAL PROBLEM
At the present time there are available collapsible containers e.g. from Clip-Lok SimPak USA, Inc. of Atlanta, Ga., for shipping articles e.g. glass sheets. The collapsible container has a base connected to walls, and the walls connected to a lid or top, by spring steel clips. The base of the presently available collapsible containers has no provisions for a person to walk through the base to retrieve articles at the rear of the container. In other words, the base has a solid deck; it does not have a portion removed or cut-out to provide a walk-in base.
With the presently available container having a solid base, to retrieve articles at the rear of the container, it may be necessary to step up onto the base, retrieve the article, and step off the base carrying the article. The reverse procedure is employed to load the container. When the foregoing techniques are practiced, the loading and unloading is ergonomically unacceptable. One solution is to reduce the depth of the base; this option is not always acceptable because it reduces the pay load of the container.
As can be appreciated by those skilled in the art, it would be advantageous to provide a collapsible container with a walk-in base to eliminate the limitations of a solid base.
SUMMARY OF THE INVENTION
The invention relates to an improved base of a collapsible shipping container of the type having sidewalls, a backwall, a frontwall and a lid held together and to the improved base in any convenient manner, e.g. by spring clips of the type sold by Clip-Lok SimPak USA, Inc. The base has a generally parallelepiped outer shape and a cut out portion in the front side of the base to allow the person unloading the rack to walk on the floor rather than on the base for ease of loading and/or unloading articles e.g. automotive transparencies such as windshields on the base. The base may be made of any material for example, wood, reinforced plastic, steel members and preferably steel tubing.
The invention also relates to a method of loading and/or unloading articles from a collapsible container having the base of the invention.
