Abstract
A beverage can end for seaming onto a can body may include a peripheral wall, a center panel, a tab attached to the center panel by a rivet (), a tear panel (), a main reference line (RM), a transverse reference line (RT), and a score (). The score may include arcuate main score () that defines a main portion of the tear panel () and a score extension () that defines a vent portion. The score may be configured such that actuation of the tab from its horizontal rest position to an intermediate position ruptures the main score portion () to pivot the tear panel main portion () about the hinge and further actuation of the tab by twisting from the intermediate position ruptures the score extension ().
