ABSTRACT:
A system for reconfiguring generally cylindrical, open-top containers that are formed from deformable metal utilizes a press to force bottom portions of a container into a die to carry out a drawing operation that alters bottom and side wall portions of the containers to elongate the containers and to provide the containers with tapered, fluted side portions that enable the reconfigured containers to be nested for empty shipment and storage in a minimum of space. As containers are reconfigured, the decrease that results in fluid-carrying capacity as side wall portions are fluted and folded inwardly is compensated for, at least in large part, by elongating the containers as by folding peripheral portions of their bottom walls upwardly to serve as extensions of their side walls. Containers such as industrial drums formed from steel and having rolled seams or the like which extend circumferentially about their bottom walls to join the bottom walls with the side walls are reconfigurable utilizing the system of this invention, and the reconfiguration preferably is effected without distorting the rims of the drums, and without causing a loss in fluid-carrying integrity or capacity. The system of the invention is advantageously utilized to effect reconfiguration of reusable industrial drums to at least double the empty drum containing capacity of valuable transportation and storage space.
