Foil Membrane Lid

摘要

The invention includes a closure for a container. The closure includes a lid, a tab including a base, an end opposite the base, and a rivet. The rivet is disposed between the base and the end. The tab is fastened to the lid at the base and the rivet such that the rivet pulls away from the lid to form a hole in the lid when the end of the tab is moved away from the lid during the opening process.

主权项

1. A method of at least partially removing a lid provided on a container to define a sealed space within the container comprising:
lifting a unitary, one piece tab, including a base attached to the lid, an end opposite the base and a rivet disposed between the base and the end opposite the base, causing:
the tab to rotate about the base and pulling the rivet away from the lid thereby forming a first hole through the lid for venting the sealed space; andthe tab to angle such that the longitudinal axis of the tab is transverse to the plane of the lid, thereby breaking a peripheral score line that defines a periphery of the lid; pulling the tab to apply a pull force to the angled tab transverse to and away from the plane of the lid to at least partially separate the lid from an end blank bonded to a perimeter of the container at the peripheral score line; and at least partially removing the lid from the container for accessing the sealed space.
