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.

A snap-on cap for use with a container having a neck and a mouth defining an upper opening communicating with the interior of the container, the neck having an annular ring extending therearound and positioned below the mouth, comprising: (a) a top wall configured and diminished such that at least a portion of said top wall is capable of contacting at least an uppermost outer surface portion of said container mouth so as to seal the container mouth; (b) a first annular sealing wall extending downwardly from said top wall, said first annular sealing wall having an outer configuration capable of snap-fitting sealing engagement with at least an inner surface portion of the container mouth; (c) a second annular sealing wall extending downwardly from said top wall and being spaced radially outwardly from said first annular sealing wall and inwardly from the periphery of said top wall, said second annular sealing wall having an inner configuration capable of snap-fitting sealing engagement with at least an outer surface portion of the container mouth; and (d) an outer wall extending downwardly from the periphery of said top wall a greater length than said second annular sealing wall, said outer wall being easily separable from said top wall so as to provide evidence of unauthorized tampering with said snap-on cap.
