ABSTRACT:
An open-top container that is generally circular in cross-section and is formed from deformable metal by utilizing a press to force bottom portions of an upwardly opening workpiece into a die to carry out drawing operations that alter bottom and side wall portions of the workpiece to elongate the workpiece and to provide the workpiece with tapered, fluted side portions that enable the resulting container to be nested with a like container for empty shipment and storage in a minimum of space. As a part of the container configuration process, each container is provided with a pluraltiy of vertically extending "flutes" that extend along the side walls of the container, 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 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.
