Description




FIELD OF THE INVENTION




This invention relates generally to storage containers, and in particular, to a storage container which may be simply and easily collapsed when not in use.




BACKGROUND AND SUMMARY OF THE INVENTION




In factories, large storage containers are often used to store bulk products. By way of example, bulk products may be placed in the storage container after fabrication. Thereafter, these bulk products are transported to various work stations throughout the factory where such products are needed for further processing. Typically, these storage containers are transported by means of forklift trucks that carry the storage containers containing the bulk products between various locales in the factory. Consequently, it can be appreciated that such storage containers must be of sufficient strength and durability to withstand repeated handling by the forklifts.




In order for these storage containers to withstand repeated transport by forklift trucks, the storage containers must be constructed from a durable material such as steel or the like. In addition, these storage containers must have large capacities to hold a substantial quantity of bulk products. While functional for their intended purpose, these types of storage containers occupy a significant amount of floor space within a factory when not in use. Consequently, it is highly desirable to provide a storage container that may be collapsed when not in use, and yet, still retains sufficient strength and stability to withstand repeated transport thereof by a forklift truck.




Therefore, it is a primary object and feature of the present invention to provide a storage container of sufficient durability to withstand repeated transport by a forklift truck.




It is a still further object and feature of the present invention to provide a storage container that may be inverted between a storage configuration wherein the storage container may receive a plurality of bulk products therein and a storage configuration wherein the storage container is collapsed.




It is a still further object and feature of the present invention to provide a storage container which is inexpensive to manufacture and that may be simply and easily collapsed to a storage configuration.
