ABSTRACT:
An easy opening closure system comprising a container end portion having an opening and a scored portion adjoining the opening. An exterior tape and interior sheet material cover the opening and sandwich the scored portion. Removal of the exterior tape initiates tear of the scored portion and permits the scored portion to be pulled back away from the opening to enlarge the opening. A preferred easy opening closure system includes a reinforcing member which is adhered to the underside of the scored portion and to the exterior tape in the area of the opening. The reinforcing member facilitates bending of the scored portion away from the opening.
