Abstract
A can end for a beverage container has a center panel about which a circumferential strengthening member extends. The center panel has a rivet attaching a tab to a public side of the center panel. The tab has a cleat formed at a nose end. The cleat intersects a diametrical line of the can end drawn through a lift end of the tab, the nose end, and the rivet. The cleat extends downwardly towards the public side of a tear panel such that a distance from a lowermost portion of the cleat to the tear panel is less than a distance of an uppermost portion of the cleat to the tear panel. The cleat has a compressed portion of the curled portion forming a substantially V-shaped crevice on an upper surface of the tab.
