  • Can end, and method of manufacture therefor
    Patent number: 6666933
    Abstract: A can end is manufactured by forming an end shell comprising a radially outer seaming flange, a chuck wall adjacent the seaming flange, a center panel, and an axially downward countersink joining the center panel to the chuck wall below the level of the seaming flange. The end shell is converted to an easy-open can end by forming a score on a portion of the center panel, raising a rivet on the center pane, and forming a tab and attaching the tab to the rivet. The end is subsequently formed by moving the center panel and the seaming flange one with respect to the other to raise the center panel above the level of the seaming flange.
