ABSTRACT:
A container end panel having a non-detachable flap portion partially severable from the panel to provide an opening. The flap portion is recessed below the remainder of the panel and is broken away by a fitment which fits into the recess. The fitment is adapted to be pushed inwardly and after rupturing the score between the panel and the flap functions to swing the flap inwardly about a hinge formed by the unscored metal connecting the flap to the panel. The fitment is pressed into the opening and snaps within the opening and provides a guard shielding the users finger from the raw edges at the tear edge about the opening. The invention is also directed to a formation of the inner edge of the ring to facilitate rupturing the score and thereafter swinging the panel inwardly.
