Abstract
Abstract A reclosable container closure for a container having an end closure ring seamed to the container body. The ring has an inward extending seating flange closure disc which is sealed to the flange during shipment and separated therefrom when the container is first opened. The closure disc also is provided with a peripheral ring of pressure sensitive adhesive suitable for holding the closure disc in position to seal the container after it is first opened. The closure disc may be formed from a plurality of laminae, the top lamina being arranged to provide a pull tab foldable out the plane thereof. The bottom lamina may be of metal to give proper stiffness to the closure disc.
