Abstract
A can lid (14) for an aluminum beverage can comprises a pull tab (38). Further, it has a chuck wall (26) defining a plug diameter, a countersink (28) and central panel (30) having a panel radius (48). On the central panel, a score line (34) defining a tear panel (32) and a rivet (40) for connecting the pull tab to the can lid are arranged. The plug diameter is between 45 to 49 mm, an outside lid diameter is between 52 to 55 mm and a lid weight is less than 1.9 gr. The central panel has a thickness of less than 0.19 mm. The score line defines an area of between 300 mm2 to 350 mm2 and the score line has a shortest distance from the panel radius of less than 3 mm.

A can lid for an aluminum beverage can, comprising:
- a curl for interconnecting the can lid to a neck of the aluminum beverage can;
- a chuck wall extending inwardly from the curl;
- a countersink interconnected to the chuck wall;
- and
- a central panel interconnected to the countersink and having a panel radius, a diameter that is not greater than approximately 40 mm, a score line defining a tear panel and a rivet for connecting a pull tab to the can lid;
- wherein the score line defines a tear panel that has an area of between approximately 24% to approximately 34% of an area of the central panel and the score line has a shortest distance from the panel radius of less than approximately 3 mm.
A beverage can, comprising:
- a body that is symmetric about a longitudinal axis and includes:
- a base end with a stand ring and a dome;
- a sidewall extending upwardly from the base end;
- and

- a chuck wall extending downwardly from the seam;
- a countersink at a lower portion of the chuck wall;
- and
- a center panel interconnected to an inner portion of the countersink, the center panel having a panel radius, a score line defining a tear panel, a rivet, a pull tab interconnected to the center panel by the rivet, and at least one ramp-up bead configured to elevate a grip end of the pull tab away from the center panel as the pull tab is rotated from a stored position to an opening position, wherein the ramp-up bead has an arcuate shape and is positioned substantially parallel to a perimeter of the center panel, and wherein a distance between a portion of the score line and the center panel perimeter is less than approximately 1.1 mm.
