Abstract
An improved easy opening container end is disclosed of the type wherein an opening tab is attached to a wall of a can end closure at a fulcrum adjacent a primary score line. The primary score line circumscribes a pore opening panel except at a hinge area. The forward portion of the opening tab is adapted to depress the pore opening panel into the container to expose a pore opening when the opening tab is pivoted about the fulcrum. The opening tab is attached to the wall by means of a rivet. One secondary score line contiguous with the primary score line projects away from the pore opening panel on one side of the rivet and another secondary score line, also contiguous with the primary score line, projects away from the pore opening panel on the other side of the rivet. In this manner, after the primary score line is severed and the pore opening panel is depressed, the opening tab may be retracted from the vicinity of the pore opening panel by severing the secondary score line so as to permit easy removal of the contents of the container and to expose an underportion of the wall for the reading of promotional indicia.
