Abstract
A closure for beverage cans including a key-shaped sealing tab delineated by a line of weakening in the top panel and a lift tab overlying the sealing tab. The sealing tab includes two parallel downwardly sloping grooves having vertical end walls. A projection having a vertical wall is disposed between the grooves. A raised, fulcrum rib is disposed adjacent the end walls of the grooves. The lift tab includes a main portion and two downwardly extending side arms interconnected by a pivot arm. The side arms are disposed in the grooves. The pivot arm is restrained for pivotal movement by the vertical wall of the projection, the end walls of the grooves and the bottom wall of a second projection formed in the lid. When the lift tab is raised, it initially pivots about the axis of the pivot arm and then about the fulcrum rib. During this latter movement, the arm portion of the lift tab applies a force to the sealing tab causing it to be partially severed and to be moved outwardly away from the pouring opening.
