  • Patent number: 4387827
    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.
