ABSTRACT:
A snap-on closure for use with a bottle having a neck and a mouth defining an opening in communication with the interior of the bottle, includes a circular top wall which contacts the uppermost surface portion of the bottle mouth. A first annular sealing wall, extending centrally downwardly from the top wall, engages and seals an inner surface portion of the bottle mouth. A second annular sealing wall also extending centrally downwardly from the top wall is spaced radially outwardly from the first annular sealing wall and engages and seals an outer surface portion of the bottle mouth. An outer wall, connected to the periphery of the top wall by a thin web membrane to permit easy separation from the top wall, extends downwardly from the periphery of the top wall a greater length than the second annular sealing wall. The outer wall has a flange extending radially outwardly from and along a major portion of its lower edge. The flange cooperates with a shoulder on the bottle neck so as to provide a flush fit with the bottle. A tear tab is connected to the outer wall to facilitate the separation of the outer wall from the top wall. In an alternative embodiment, the outer wall is frangibly connected to the lower periphery of the second annular sealing wall.
