09815590 · 2017-11-14 · ·

A beverage can end for seaming onto a can body may include a peripheral wall, a center panel (26), a tab (attached to the center panel by a rivet (28), a tear panel (60), a main reference line (Rm), a transverse reference line (R1), and a score (30). The end includes an anti-fracture score (40) proximate a vent score (70). The center panel includes a recess (27), in which the main score, an antifracture score, and (optionally) the anti-tension score (50) are located. The score is configured such that lifting 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 (70) and a second lifting operation or twisting operation of the tab ruptures the main score extension (34).

Can end having a main score and a score extension

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 (56), a tear panel (41b), a main reference line (RM), a transverse reference line (RT), and a score (31b). The score may include arcuate main score (31b) that defines a main portion of the tear panel (41b) and a score extension (32b) 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 (31b) to pivot the tear panel main portion (40b) about the hinge and further actuation of the tab by twisting from the intermediate position ruptures the score extension (32b).
