Abstract
A bottom profile for a cylindrical two-piece drawn steel can is configured during manufacture so that the resultant bottom profile shape includes areas of highly worked metal positioned to assume processing stresses. A bottom wall bead is included and has a prescribed cross-sectional configuration to provide maximum abuse resistance and to be functionally and operationally interchangeable in the packing and processing line with traditional three-piece containers. Moreover, the prescribed bead configuration works to improve stacking crush resistance by work hardening the metal adjacent the corner between the bottom and wall of the can.
