Apparatus for supporting a workpiece

A metallic container having an outwardly flexible bottom wall adapted to flex to an outwardly generally convex position under pressure from within the container is provided with integral tripod-type support structure for the container in the bottom wall comprising an inwardly concave center portion of compound curvature having a generally equilateral triangular shaped bottom wall area extending generally radially outwardly therefrom and providing three equilaterally spaced support areas in the outwardly flexed convex position. Methods and apparatus for forming the integral tripod-type support structure comprise forming the concave center of compound curvature by a doming die with portions of the equilateral triangularly shaped bottom wall area located axially inwardly a lesser distance than other portions of the concave center in an inwardly flexed position so as to be located axially outwardly a greater distance than other portions of the bottom wall in an outwardly flexed position, thereby forming the tripod-type support structure on the bottom wall during movement from the inwardly flexed position to the outwardly flexed position under pressure of the contents of the can.
