Abstract: A double action tooling press apparatus for forming a beverage can lid has a longitudinal axis, an inner tooling assembly, and an outer tooling assembly. The inner tooling assembly is positioned about the longitudinal axis and has a downwardly extending stem. The stem has an upper segment having a free end and a separate lower segment having a proximal end. The proximal end is in operative communication with, but is not joined to, the lower free end of the upper segment. An opposing distal end is joined to a punch core tool. The outer tooling assembly is positioned about the longitudinal axis and has a passageway through which a portion of the stem passes, a chamber in which the proximal end of the lower segment of the stem resides and traverses upwardly and downwardly therein, a biasing means within the chamber for biasing the lower segment of the stem in an upward position, and a circumferential tooling assembly.
Abstract: A method of forming two-piece beverage can components is described. The method requires providing a plurality of pre-punched metallic disks. A disk feeder transfers at least one of the plurality of pre-punched metallic disks to a first process station in a plurality of processing stations. The first disk is deformed during a two-piece beverage can component manufacturing process is performed at the first station. The deformed disk is removed from the first station and transferred to each subsequent processing station in the plurality of processing stations. Further two-piece beverage can component manufacturing processes are performed in each subsequent processing station to produce a substantially finished two-piece beverage can component.

Abstract: A can end and can body are seamed to each other using a seaming roller, seaming chuck and a laser fusing the peripheral portion of the can end to the can body. Laser seaming allows less metal to be used in the can end and can body. The can end and can body seam is further reinforced in order to ensure that the can is capable of withstanding internal pressures. The reinforcing techniques include crimping the seam with one or more crimping rollers, reforming the seam so as to incline the seam towards a central axis extending through the center of the can end and can body, and using multiple laser welds spaced apart from each other in the vicinity of the seam.

Abstract: A container has a selectively openable panel defined at least in part by a frangible score groove in a surface of the container. The frangible score groove is selectively fracturable by a lifting action administered by a user to a secured to the container. The tab has a nose portion separated from a lift end by a central webbing. The central webbing has a hinge region and a rivet island. The rivet island is at least partially surrounded by a first void region. The central webbing also has a grab portion at the lift end of the tab. The grab portion has an enclosed region defining a billboard surface. The billboard surface has a top side and a bottom side opposite the top side. A bead created by displacing the material of the central webbing is located on the billboard surface. A pigment-carrying layer covers at least a portion of the billboard surface. A tactile indicium is located on the billboard surface.
Abstract: 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.

Abstract: A cap for sealing a container having a lug-type closure assembly is described. The cap has a top panel and a circumferential side wall panel. The top panel is positioned about a longitudinal axis and extends radially outwardly therefrom. The circumferential side wall panel is integral with an outer peripheral edge of the top panel and has first second, and third segments. The first segment extends downwardly. The second segment extends radially outwardly at a first angle to the first segment. The third segment extends downwardly from the second segment at a second angle to the second segment.
Abstract: A can end member for a beverage container is disclosed. The end member has a curl at least substantially defining a perimeter of the can end, a chuck wall extending downwardly and radially inwardly from the curl, and a central panel wall centered about a longitudinal axis. The central panel wall has a product side and a public side. The public side has a means for opening a frangible panel segment. The end member also has a fold joining the chuck wall with the central panel wall. The fold has an opening. A fluid is located adjacent the opening.

Abstract: A beverage can end is described. The beverage can end has a curl defining a perimeter of the can end, a chuckwall extending downwardly and radially inwardly from the curl, and a transition wall joining the chuckwall to an outer peripheral edge of a center panel. The transition wall is formed in compression such that a portion of the transition wall exhibits a compressed segment having a thickness which is 1% to 20% thicker than a thickness of the center panel.

Abstract: In a method of forming a beverage can end wherein a beverage can end shell has a curl defining a perimeter of the can end, a chuckwall extending downwardly and radially inwardly from the curl, a generally U-shaped countersink joining the chuckwall to an outer peripheral edge of a center panel, a method of forming an arcuate chuckwall in the beverage can end shell is described. The method of forming the arcuate chuckwall comprises the steps of providing a partially formed can end, providing an upper tooling having an annular, generally arcuate segment, and providing a lower tooling having a circumferential, generally arcuate, outwardly convex segment in at least partial alignment with the annular, generally arcuate segment of the upper tooling. The annular, generally arcuate segment of the upper tooling and the circumferential, generally arcuate, outwardly convex segment of the lower tooling are brought into engagement with a public side and a product side of the partially formed can end, respectively.
