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.

A container end member or the like for sealed association with a container member to provide a sealed container and which is provided with a system for forming an opening therein comprising: a one piece metallic end member having a cylindrical peripheral rim wall portion and a central axis; an annular outer rim portion on said metallic end member for sealed association with the container member; a central end wall portion integrally connected to said rim portion and extending generally transversely to said central axis and having an outer surface and an inner surface; a severable tab portion in and integrally connected to said central end wall portion; a hinge portion integral with said central end wall portion and having spaced apart ends; severable score line groove means having ends adjacent to said spaced apart ends of said hinge portion and defining said severable tab portion so that said severable tab portion may be severed from said central wall portion in response to applied axially inwardly directed forces and form an outlet opening in said central end wall portion; retaining means comprising said hinge portion for retaining said severed tab portion attached to said central end wall portion; force applying means for applying said axially inwardly directed forces on said severable tab portion; said force applying means comprising: an integral plastic member formed from a relatively rigid plastic material; an attachment means portion integral with said plastic member for securing said plastic member to said central end wall portion; said plastic member having an elongated body portion having an abutment end portion at one end thereof and a handle portion at the other end thereof; and a pivot means portion integral with said attachment means portion and said elongated body portion for pivotally mounting said elongated body portion on said central end wall portion so that when an axially outwardly directed opening force is applied to said handle portion, said elongated body portion will pivot about said pivot means portion so that said abutment end portion will apply said inwardly directed force to said severable tab portion to sever said severable tab portion along said severable score line groove means and form said outlet opening in said central end wall portion.
