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.
