<p>A method for strengthening an end member (10) for a container comprises the steps of providing an end member shell (89) and reforming the end member shell (89). The finished the end member has a central panel wall (12) with a product side and a public side. The public side has a means for opening a frangible panel segment. The end member shell (89) has a central panel (12) extending radially outwardly from a central axis (x, y), a panel radius (102) along a peripheral edge of the central panel (12), a countersink (16) integral with the panel radius (102), a chuckwall (15) extending upwardly from the countersink (16) having a bend (108) with a radius of curvature (Rscwq) and angled axially outwardly, and a seaming curl (14) defining the outer perimeter of the end member shell (89) and integral with the churckwall (15). The chuckwall (15) of the end member shell (89) is reformed to decrease the radius of curvature(Rscwq) of the bend (108).</p> |
