Abstract
A beverage can end for connection with a can body having a necked-down top, and wherein the center expansion panel of the end forms a gate which is pushed downwardly into the can to open it. This provides, essentially, an open-top-can wherefrom a beverage may be drunk in the same manner as if it were a glass or a cup. The can end, of drawn metal, includes a triple fold reinforcement ring constituting a chuck panel adjacent to the chuck wall of the peripheral seaming ring of the end. The upper layer of the triple fold connects with the bottom of the chuck wall and the lower layer with the center expansion panel. A score-cut about the underside of the lower layer, with a short uncut portion forming a hinge, permits the center expansion panel to be separated from the triple fold and pushed downwardly to open the can. A modified embodiment of this end restricts the score-cut to a segment of the triple fold ring whereby only a portion of the center expansion panel may be pushed downwardly to form an opening at one side of the can end.
