A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with a lower wall portion of a chuck wall, and the chuck wall has an upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall.

A thinned metal can end having a non-uniform thickness profile is provided. The can end has a central panel having at least a first thickness, a middle portion having at least a second thickness greater than the first thickness, and an end portion having at least a third thickness greater than the first and second thicknesses. The can end is configured to be joined to a can wall by a double seam.

A method of making a can end, which includes a recessed panel defined by an upwardly extending chuck wall, a peripheral scoreline disposed in a public side of the panel proximate to the base of the chuck wall, a tab fastened to the panel by a rivet, includes the step of employing tooling to form a pressure resistance bead extends around the panel inboard of the peripheral scoreline and outboard of the rivet. The tooling forms a saw tooth panel formation proximate to the pressure resistance bead inboard of the pressure resistance bead. Among other benefits, the pressure resistance bead and saw tooth panel formation created by the tooling and method combine to resist wrinkling or other undesired deformation of the can end.

A container having a wall, where the wall includes a score line that defines a removable lid, where the score line defines the perimeter of the lid. The container lid includes a protective component extending inwardly of the perimeter of the lid and covering a sharp edge of a burr formed by removing the lid from the wall.

A tamper evident container comprises a base, a lid, a first hinge, a locking mechanism, a second hinge, and a tamper evidence feature. The base retains items for storage. The lid engages with and covers the base. The first hinge rotatably couples the base and the lid. The locking mechanism secures the lid to the base and includes a plug and a receptacle. The locking mechanism is engaged when the plug is within the receptacle. The second hinge rotatably couples the base and the plug. The tamper evidence feature provides evidence of the container being tampered with or opened and is positioned between the plug and the second hinge.

A can lid shell 10 includes a panel section 11 having a circular peripheral edge, a countersink section 12 formed and recessed along the peripheral edge of the panel section 11, a chuck wall section 13 rising from an edge of the countersink section 12, and a flange section 14 protruding from an upper end of the chuck wall section 13. The countersink section 12 includes a first curved surface portion 123C that is convex toward an internal space SP1. The chuck wall section 13 includes a second curved surface portion 131 that is connected to the first curved surface portion 123C and that is concave toward the internal space SP1. Furthermore, the second curved surface portion 131 and the first curved surface portion 123C are formed to be thicker as both are directed from an edge p8 on the flange section 14 side to an edge p6 on the panel section 11 side.

A can end (10) for a two-piece beverage container (1) has a public side (32) opposite a product side (34). A cured coating (76) is on the product side (34) of the can end (10) and forms a substantially continuous thin layer thereon. A circumferential curl (12) is centered about a longitudinal axis (50). A circumferential chuckwall (14) extends downwardly from the curl (12). A circumferential U-shaped countersink (16) is located downwardly from the chuckwall (14). The countersink (16) has an annular bead defining a lowermost vertical extent of the can end (10). A center panel (18) is located radially inwardly from the countersink (16) and is centered about the longitudinal axis (50). The center panel (18) has a means for providing an opening in the can end (10). A circumferential second coating (92) forms an annular layer on the product side (34) of the circumferential curl (12) and the cured coating (76). The second coating (92) provides a layer on one or more fractures in the cured coating (76).
