  • Publication number: 20040099665
    Abstract: An easy-opening can end and tools for making the same in which the can end is intended for cans of food products or other non-pourable products in which the can end has an improved pull tab attached to a relatively large removable panel portion and in which the tab has a bending fulcrum behind the rivet to facilitate severance of the score around the removable panel. The tab has a C-shaped slot in it around the side of the rivet toward the center of the can end to permit limited bending of the tab along the fulcrum line.

  • Patent number: 4530631
    Abstract: An easy open can end having a retained tear strip extending diametrically partly across the can end defined by a score line, and a graspable pull tab adjacent and outside the open end of the score line. The pull tab is provided with a nose portion to initiate a tear along the score line upon lifting of the pull tab. The edges of the nose portion are curled into a cylindrical cross-sectional shape to provide a high beam strength and to rigidize the nose portion and to prevent failure by bending before the tear strip is opened. A method for manufacture of the pull tab includes forming at least one relief knotch in the peripheral edge of the pull tab blank at the nose end thereof, whereby to relieve compressive forces when the edge is curled, and curling the peripheral edge of the nose portion in successive steps to form an edge portion of continuous cylindrical cross-sectional shape.
