Abstract

A method and apparatus for scoring a metal container end to provide a tear-out panel, wherein the scoring is accomplished with a greatly reduced tendency for any internal protective coating on said end to be damaged and for the residual metal in the score line to fracture. During the scoring operation the container end is supported on an anvil die having an arcuately domed rib thereon which, in cooperation with the advance of the scoring indenter, works the metal in the lower portion of the metal sheet and distributes the working stresses normally produced in the metal during the scoring operation.
