Abstract
A closure for a container, and a method for producing the same, wherein the closure includes an end panel and a plastic frame member connected together and which can be place over, or snapped onto, and then the frame member can be permanently attached and hermetically sealed to the flange of a metal, glass, plastic or composite container or can. The interface of the end panel and frame member is such as to hermetically, seal the container and yet the end panel can be readily peeled from at least a portion of the frame member for gaining access to the interior of the container. A pull tab, or ring, is provided to assist in peeling the end panel to an open position. Depending on the manner of attaching or securing the end panel to the frame member, separation or peeling can result from an adhesive failing or from a cohesive failing of the material forming the frame member, or the end panel, or the adhesive.
