Abstract
A container end member provided with a score line groove defining a severable tab portion that can be severed by applying an inwardly directed force thereto and a hinge portion for retaining the severable tab portion attached to the container end member and a one-piece integrally formed plastic member pivotally secured to the container end member and comprising an elongated body portion having an abutment end portion overlying a portion of the severable tab portion for applying the axially inwardly directed force thereto and a transverse handle end portion overlying another portion of the container end member so that when an axially outwardly directed force is applied to the transverse handle end portion, the elongated body portion will pivot relative to the container end member so that the transverse abutment end portion will apply the axially inwardly directed force to the portion of the severable tab portion to sever the severable tab portion along the score line groove and form an outlet opening in the container end member.
