ABSTRACT:
A closure is provided and includes a sealing member and a cover for sealing and closing a container opening. The sealing member is sealed to the inner and outer walls of the container, and in one embodiment, an annular, ring-shaped element is provided for supporting the sealing member on the inside surface of the cover. In all embodiments, the cover includes a flange sealed to the external wall of the container, with the flange including a line of perforations forming a tear strip for removing the cover from the container. In the preferred embodiment, the removal of the cover causes the ring-shaped element to penetrate the sealing member and to form an annular opening in the sealing member so that the contents may be smoothly poured from the container.
