Patent number: 7556168Abstract: A can end member has a center panel, a circumferential chuck wall, and a transition wall. The center panel is centered about a longitudinal axis and has a peripheral edge. The center panel also has a step portion located radially outwardly from the longitudinal axis. The step portion has an annular convex portion joined to an annular concave portion and displaces at least a portion of the center panel vertically in a direction parallel to the longitudinal axis. The curl defines an outer perimeter of the end member. The circumferential chuck wall extends downwardly from the curl to the transition wall. The transition wall connects the chuck wall with the peripheral edge of the center panel. The transition wall comprises a folded portion. The folded portion has a first leg, a second leg, and a third leg. The first leg is directly connected to the chuck wall and joined to the second leg by a concave annular portion.Type: GrantFiled: May 14, 2004Date of Patent: July 7, 2009Assignee: Rexam Beverage Can CompanyInventors: Timothy L. Turner, Randall G. Forrest, Rajesh Gopalaswamy, Michael R. Gogola

Publication number: 20040211786Abstract: An end member (130) for a container has a central panel (12) extending radially outwardly from a central axis. A first panel radius (114) is located along a peripheral edge of the central panel (12). A countersink (16) is integral with the first panel radius (114). A chuckwall (15) extends upwardly from the countersink (16) to a seaming curl (14) located at an outer perimeter of the end member (130). An approach point (134) is defined by a lower outer position of an axially stacked second end member (132). A bend (108) is located on the chuckwall (15). The bend (108) having an outwardly directed angle with a radius of curvature (RCW1) which adapted to position the chuckwall (15) radially outwardly of the approach point (134) and in spaced relationship thereto.Type: ApplicationFiled: May 17, 2004Publication date: October 28, 2004Inventors: Timothy Turner, Randy G.

Patent number: 6748789Abstract: 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.Type: GrantFiled: October 19, 2001Date of Patent: June 15, 2004Assignee: Rexam Beverage Can CompanyInventors: Timothy Turner, Randy G.
