Abstract
A can end for a two-piece beverage can is described. The can end has a center panel positioned about a vertical center axis. The center panel has a means for opening the can end located on a public side. A circumferential strengthening member is located about the center panel. A wall extends upwardly from the circumferential strengthening member. A curl is joined to an upper end of the wall. The curl defines an outer perimeter of the can end. A reinforcing bead is located on the wall between an uppermost portion of the wall and a lowermost portion of the wall.
