the easy opening end closure for attachment to a can body . the end closure includes a plastic pull tab having a closure tab sealed in a slit which defines a displaceable closure . the pull tab is attached by forging a plastic strip over a lid in a manner such that the plastic is caused to flow and force the metal panel against a cutting edge to form a slit defining a displaceable closure . at the same time the forged plastic flows beneath the adjacent edges of the slit to form a tight seal therein .
