ABSTRACT:
A bottom profile for a cylindrical two-piece drawn steel can is configured during manufacture so that the resultant shape may subsequently be altered by pushing downward at the outer profile ring adjacent the periphery with a simple cylindrical tool, thereby achieving a finished container with the desired configuration to be functionally and operationally interchangeable in a packing and processing line with traditional three-piece containers.
