Abstract

A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inclined inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with an inclined lower wall portion of a chuckwall at a junction below the center panel, and the chuckwall has a curved or inclined upper wall portion which connects with an inner wall of the crown. The chuckwall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall. The inclined upper wall portion of the chuckwall extends at an angle greater than the angle of the inclined lower wall portion of the chuckwall.
