Patent number: 7748563Abstract: 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: GrantFiled: May 17, 2004Date of Patent: July 6, 2010Assignee: Rexam Beverage Can CompanyInventors: Timothy Turner, Randy G.

Patent number: 7000797Abstract: An end member for a container having a circumferential sidewall, the end member having a peripheral seaming edge adapted to be integrally connected to the sidewall, and having a central panel wall with a means for opening a frangible panel segment of the panel wall is claimed. The end member comprises a deboss panel recessed in the central panel. The deboss panel has first and second spaced apart end portions joined by first and second sidewalls. The first spaced apart end portion has an apex and first and second arcuate portions. A distance between the first and second arcuate portions is defined by a plurality of progressively increasing secant lengths located in spaced relation from the apex. A score groove is located within the deboss panel defining an outer perimeter of the frangible panel segment. The score groove has a first end and a second end joined to the first end by a curvilinear segment. The first end and the second end are separated by a generally linear hinge segment of the central panel wall.Type: GrantFiled: December 12, 2002Date of Patent: February 21, 2006Assignee: Rexam Beverage Can CompanyInventors: 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.

Patent number: 6161717Abstract: The present invention provides an end closure for a container having a central panel wall with a displaceable opening panel defined by a frangible score and a non-frangible hinge segment. A tab is attached to the panel wall by a rivet, the tab having a nose extending over a first area of the opening panel, the remainder of the opening panel which is exposed from the tab defining the second area of the opening panel. A deboss bead resides in the opening panel, formed in the second area. The deboss bead being curvilinear in shape, formed as a narrow channel in the opening panel. The narrow channel preferably being formed as a U-shaped bead with a first wall and a generally opposed second wall, with the first and second wall being joined by an arcuate intermediate segment. The end closure further has a deboss panel residing in a plane below the remainder of the panel, the deboss bead extending below the plane of the deboss panel.Type: GrantFiled: February 5, 1999Date of Patent: December 19, 2000Assignee: American National Can CompanyInventors: Randy G.
