ABSTRACT:
A seal and closure for a container end includes a metal foil seal having a cylindrical part sealed to the inner surface of the container adjacent the end, a transverse diaphragm part recessed inwardly from the end, and a tear tab on the diaphragm. An annular groove is formed in the cylindrical part between the container end and the diaphragm, the groove defining a tear line so that the membrane and the inward portion of the cylindrical part separate from the remainder thereof when the tear tab is pulled. An insertable lid covers the seal.
