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.

In an improved two-piece metal can having a seamless container body of circular cross-section formed of a thin material into an integral side and bottom wall, a circular closure adapted to be joined to said side wall by an annular doubleseam having five adjacent layers of metal, the improvement wherein the profile of the area next adjacent the juncture of the side and bottom wall includes: (a) an outwardly radial extending lower side wall portion forming a chime-like bead having its most distal extent near the bottom periphery, (b) a substantially flat circular ring-shaped section extending generally normal to said side wall portion and in-line with the bottom most plane of the container bottom, (c) an interior annular side wall extending into the container from the bottom most plane of said bottom and joining the inside edge of said ring-shaped section to a recessed central panel of said bottom, and (d) an annular convolution disposed substantially intermediate said bottom distal extent of said chime-like bead and said inside edge of said ring-shaped section, said convolution being located at said substantially flat circular ring-shaped section.
