Abstract
A closure is shown for closing an opening of a vessel. The closure includes a stopper, a shield, and a pusher. The stopper seats at least partially within the vessel opening. The shield includes a recess configured to receive the stopper and at least partially defined by the inner surface of a skirt. The skirt is positioned outside the generally cylindrical neck of the vessel when the stopper is seated in the vessel opening. The pusher extends into the recess of the shield. The pusher is configured to push the stopper out of the opening when the shield is withdrawn axially, as when removing the closure from the opening. A method of assembling a closure is also shown, in which the pusher is positioned to push the stopper out of the opening when the shield is withdrawn axially from the vessel opening.
