Abstract: There is a closure 1, which is, in this case, shown as closing a mouth 2 of a bottle 3, wherein the bottle is made of glass and has an external outwardly extending integral collar 4 which extends fully around an outside of the neck of the bottle and is of a constant shape and size at any location around the periphery. The seal 5 is held under compression against an uppermost rim 6 of the bottle mouth 2 and surface 7, which is adapted to engage with compression force the seal 5. Upon extraction of portion 8 from within the mouth of the bottle, a “popping” sound is achieved by having the position of the seal somewhat below the mouth prior to extraction so that there will be upon extraction an evacuation of the headspace within the bottle.

Abstract: A closure (1) closes a mouth (2) of a bottle (3), wherein the bottle is made of glass and has an external outwardly extending integral collar (4) which extends fully around an outside of the neck of the bottle and is of a constant shape and size at any location around the periphery. The seal (5) is held under compression against an uppermost rim (6) of the bottle mouth (2) and surface (7), which is adapted to engage with compression force the seal (5). Upon extraction of portion (8) from within the mouth of the bottle, a “popping” sound is achieved by having the position of a sealing part (9) of the portion somewhat below the mouth prior to extraction so that there will be upon extraction an evacuation of the headspace within the bottle.
