Abstract
A method for strengthening an end member for a container comprises the steps of providing an end member shell and reforming the end member shell. The finished the end member has a central panel wall with a product side and a public side. The public side has a means for opening a frangible panel segment. The end member shell has a central panel extending radially outwardly from a central axis, a panel radius along a peripheral edge of the central panel, a countersink integral with the panel radius, a chuckwall extending upwardly from the countersink having a bend with a radius of curvature and angled axially outwardly, and a seaming curl defining the outer perimeter of the end member shell and integral with the chuckwall. The chuckwall of the end member shell is reformed to decrease the radius of curvature of the bend.
