Abstract
A container is provided which includes a container body, a cap closure and a plastic membrane. The container body has a receiving area capable of holding a product. An open mouth surrounds the receiving area. A cap closure is arranged over the open mouth. The cap closure includes a fitment engageable around the mouth and a lid hingedly connected to the fitment. The plastic membrane is integrally molded with the cap closure and sealingly prevents leakage from the receiving area. The membrane includes a minor area non-frangibly attached to the fitment having a V-shaped outer border with sections of the border converging to a pivot point, and a major area tangibly attached along its perimeter to the fitment and to the V-shaped outer border. A pull tab is formed on a surface of the membrane at the pivot point.
