Abstract:
1. A hermetically sealed container comprising: a hollow body terminating in a neck portion defining an opening and including a downwardly and outwardly extending circumferential ramp and a circumferential groove between the ramp and the opening; a frangilbe, twist-off access closure including a unitary grip tab and occluding the opening; an axially moveable overcap rotatably mounted to the container surrounding the access closure and neck portion, the overcap including a top portion and a unitary skirt portion terminating in an expandable rim having plural flexible dentils with inwardly extending distal beads, around the periphery thereof, the circumferential groove adapted for engagement with the inwardly extending distal beads of the dentils; the top portion defining at least one elongate slot adapted to engage the grip tab, and the ramp adapted for engagement with the inwardly extending distal beads of the dentils so as to increasingly deflect the dentils in an outward direction storing a bias force in the dentils which increases with increasing deflection of the dentils when the overcap is pushed toward the access closure and then rotated about the neck portion to twist-off the access closure.
