Abstract
A can end of the easy opening type comprises an end panel having a preformed dispensing opening and a push tab member having an integrally formed rivet for attachment to the end panel. In one embodiment, the end panel includes a peninsular hinge portion having a rivet receiving opening therein such that all deformation during opening is substantially limited to the hinge portion rather than the push-tab member. In another embodiment, an actuator opening is located between the dispensing opening and the rivet receiving opening of the end panel so as to permit a finger engageable protuberance on the push-tab member to extend therethrough.
