Composite closure and method of making same

摘要

A closure for press-on application to, and rotational removal from, a container having a cylindrical neck which includes a plurality of vertically spaced helical threads formed on the outer surface thereof. The closure includes an end panel member having a central portion formed of metal or other suitable oxygen barrier material which is adapted to overlie a mouth of the container. A generally cylindrical plastic skirt on the closure is formed by molding the same in surrounding and capturing relation to the end panel and at least a portion of the upper and lower surfaces of the end panel are generally free of plastic. The closure also includes a gasket which is engageable with the neck portion of the container to provide a seal therewith. A free edge on the outer periphery of the end panel member is encapsulated by at least one of said gasket and said molded plastic skirt.
