Abstract
A non-circular can end for a container having walls which form an opening includes a corner-mounted pull tab opener secured to a severable panel portion by an integral rivet. The corner-mounted opener facilitates easy opening of the can end. A pair of generally parallel bead recesses on either side of the integral rivet stiffen the severable panel portion in order to facilitate bending of the panel aft of the rivet to easily open the can end. The severable panel optionally further includes a mustache-shaped scoreline to reduce the amount of force required to lift the opener. Tooling and a conversion press for converting shells into the non-circular can ends are also disclosed.
