ABSTRACT:
An easy-opening can end includes a dispensing opening covered by a pivoting tab located on the interior side of the end. The pivoting tab is adapted to be pushed inwardly so as to break the seal at the dispensing opening and subsequently pivoted to the open position in response to movement of a finger engageable portion. The tab is fastened to the can end at an area of pivotal attachment. The area of pivotal attachment is connected to the can end by a peninsular region and separated from a part of the can end by a score or a lance line. Prior to pivoting the tab, the area of pivotal attachment is depressed at the score or lance line to vent the can.
