Abstract

Manually operable closure for a bottle with an externally flanged collar, which includes a hollow hull having a hole with primary and secondary flares, the latter ending in a flap turned inward at the mouth of the hull at the junctions between the hole and the flares , while a sealing device is slidably disposed within the flares and comprises a disk with a very loose fit in the primary flare and with elastic jaws extending radially from the periphery of the disk and bent to expand normally outwards and downwards in the secondary flare, the ends of the jaws having teeth turned inward, which rest against the flange to retain the sealing device in the helmet, and a rubber gasket being fitted against the outer face of the disk and provided with means for retaining the joint in armed relationship with the disc, whereby the closure, when applied to a bottle With an externally flanged neck pressing it axially therein, it responds by allowing the obturator device to slide farther into the primary flaring during bending inwards of the jaws due to its engagement with the projection between the flares and the consequent constriction of the jaws for extend the teeth inwardly below the neck of the neck of the bottle, while the latter is obturably pressed against the gasket and the jaws remain inclined outward at substantial angles to allow the helmet to tilt relative to the shutter until it is stopped by the engagement of the lower portion of the hull with the neck of the bottle without disturbing the seal between the sealing device and the neck of the bottle.
