Abstract (en)
[origin: WO8912584A1] A closure (1) for a container having an externally screw threaded neck (9), said closure (1) being moulded in one piece from a resilient plastics material and comprising a top (4) and a dependingskirt (2) which has on its internal surface a complementary screw thread (3), characterised in that an annular sealing rib (6) projects downwardly from the top (4), the rib (6) includes a first substantially cylindrical portion (7) contiguous with the top (4) and lying adjacent to or abutting with the skirt (2) and a second, frusto-conical, portion (8) contiguous with the end of the first portion (7) distal to the top (4) and extending radially inwardly to terminate in a circular free edge, the internal diameter of the first portion (7) being equal to or only slightly larger than the external diameter of the neck (9) of the container to which the closure is to be attached such that, during threaded engagement of the closure (1) with the neck (9), the second, frusto-conical, portion (8) will be engaged by a free end of the neck (9) and folded back against the first, substantially cylindrical portion (7) of the rib (6) and to form a gas-tight seal between the neck (9) of the container and the closure (1).
