Abstract
A multiple-motion easy-open closure for a can which has two rivets on the end panel, one rivet pivotably connecting a tab to the end panel and functioning to aid in cracking the score and the second rivet anchoring the tab to the end panel. The tab has a slot flanked by ribs and must be rotated until the second rivet, which extends through the slot has its head in alignment with a circular opening in the slot through which the tab may be lifted to rupture the score. The ribs are positioned tangentially to the arc of pivot of the tab and must be laterally deflected and assume an arcuate contour concentric with the pivot arc to accommodate passage of the second rivet between locked and unlocked positions.
