ABSTRACT:
A system for reconfigurating generally cylindrical, open-top containers that are formed from deformable metal utilizes a press to force bottom portions of upwardly opening, substantially cylindrical containers into a die to carry out drawing operations that alter 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 a part of the container reconfiguration process, each container is provided with a plurality of vertically extending "flutes" that extend along the side walls of the reconfigured containers, and with at least one ring-like formation that serves to enhance container strength, container stability and/or container handling characteristics. In preferred practice, each container is provided with a pair of vertically spaced, circumferentially extending ring-like formations that are located atop upper end regions of the vertically extending flutes, with these ring formations being provided by expanding upper side wall portions of the container. In preferred practice, each container also is provided with one press-formed, downwardly extending ring-like formation that provides a juncture between the reconfigured container's fluted side wall and a raised bottom wall portion that is of substantially circular configuration. The depending ring formation preferably provides a planar bottom surface for supporting the container atop a flat surface with good stability. The bottom wall preferably has a slightly raised, centrally located "crown" formation.
