Abstract:
1. A combination of a screw-top container and a screw-top closure being completely screwed onto said container in a final, sealed position on said container, wherein: said screw-top closure comprising a cap portion and a closed ring portion; said cap portion comprising an internal threading; said container comprising a mouth portion; said mouth portion comprising an external threading being configured and disposed to engage with said internal threading of said cap portion to permit said screw-top closure to be screwed onto said mouth portion to seal and close said container; said container comprising a neck portion adjacent said mouth portion; said closed ring portion being disposed to completely encircle said neck portion of said container; said closed ring portion being detachably connected to said cap portion by a plurality of breakable connecting structures to permit detachment of said closed ring portion from said cap portion; said closed ring portion comprising a plurality of engaging surfaces disposed on the inner cylindrical surface of said closed ring portion; said neck portion comprising a plurality of engaging surfaces being configured to be engaged by said engaging surfaces of said closed ring portion to minimize rotational movement of said closed ring portion upon an unscrewing movement of said screw-top closure; each of said engaging surfaces of said closed ring portion being disposed adjacent and to face an engaging surface of said neck portion; said engaging surfaces of said closed ring portion and said engaging surfaces of said neck portion being configured and disposed to minimize the angular distance between at least one pair of adjacent, facing engaging surfaces, to thereby minimize rotational movement of said closed ring portion upon an unscrewing movement of said screw-top closure, and to thereby cause engagement of said at least one pair of adjacent, facing engaging surfaces and immediately subsequent, substantially simultaneous breakage of all of said plurality of breakable connecting structures prior to opening of the seal between said screw-top closure and said mouth portion of said container upon an unscrewing movement of said screw-top closure.
