Patent ID: 7757889

Claim:
A resealing device for a container having an aluminum top with a tab opening mechanism engaging a scored flap in said top for forming a contents dispensing aperture, when the scored flap is removed, the resealing device comprising: a hollow plug made of a non-toxic, flexible material; said plug having a thin, flexible wall membrane defining a hollow wedge shaped plug with a top, a bottom and sides forming a hollow in an interior chamber; said interior chamber having a wedge shape; said plug having a midsection shaped to conform to a shape of the contents dispensing aperture; said plug having tapered outer sides and the top having a breathing hole communicating with the hollow in the interior chamber; wherein an upper portion of the plug above the midsection forms a user grip; wherein a forcing of the plug by the user places a base of the plug below the contents dispensing aperture, thereby forming a seal comprising an indentation of the flexible wall membrane all along a periphery of the contents dispensing aperture; wherein the breathing hole allows airflow out of the interior chamber of the hollow when the user grip is squeezed by a user; and wherein after a release of the user grip by the user, air fills the hollow of the interior chamber via the breathing hole as the flexible material springs back to its original wedge shape, creating a reinforced seal so that a beverage in the container retains its carbon dioxide gas longer, thus preventing the beverage from tasting flat.
