摘要：
A bottle closure of flexible thermoset synthetic material has a corrugated annular insert and an outer wall depending from its base. A thinned portion in the base is of a thickness and geometry adapted to burst at a predetermined pressure within the bottle. An annular shoulder on a severable skirt extends laterally beyond the outer wall which fits against the end of a plunger for urging an internal annular bevel groove in the skirt over an external annular bead near the mouth of the bottle.
