Abstract: This invention provides an end member adapted for sealed engagement with a container member wherein the end member has a central end wall portion which includes a severable tab portion. A hinge portion is integral with the central end wall portion and has spaced apart ends. At least one severable score line groove is formed in the central end wall portion and has a main body portion having end portions which define the spaced apart ends of the hinge portion and also defines the severable tab portion which may be severed by axially inwardly directed forces applied thereto so as to form an outlet opening in the central end wall portion. The hinge portion retains the severed tab portion attached to the central end wall portion.
