Description

FIELD OF THE INVENTION

The present invention relates generally to bulk containers, and more particularly bulk containers which are adapted to collapse into flatly stackable and storable configurations when not in use.

BACKGROUND OF THE INVENTION

Processes that utilize materials provided in powdered, pelletized, and other loose forms are often provided in bulk quantities not readily usable in manufacturing or other environments without dedicated material handling infrastructure. For example, loose materials may arrive at a manufacturing site via rail car and must be placed in an intermediate container for use. In other examples, loose materials are provided in soft-sided or minimally structured bags that cannot be safely opened for use without creating hazards relating to spilling of the loose materials. In response, processes that rely on the utilization of loose materials have employed containers made from materials such as cardboard, wood, and metal to improve material handling. These containers may be permanent rigid structures, one-time use, or capable of being assembled for use and disassembled for storage. In some instances, these containers, once erected, are not able to be collapsed for convenient storage, or are heavy and unwieldly to collapse for storage. In other instances, the containers lack the requisite strength to be stacked or on top of other containers.

Thus, there is a need for an improved container for containing loose materials that is readily convertible between collapsed and erected configurations and easily storable in the collapsed configuration.
