摘要： The invention provides container closure assemblies, especially for carbonated beverage containers, having substantially helical second thread segment (20) with a profiled lower thread surface (24). The profiled lower thread surface (24) includes a first, lower region (28) with a low pitch and a second region (30) with a steep pitch. The thread (20) may also include a step feature (32) to block unscrewing of the closure at an intermediate position where gas venting can take place, and a third region (34) of the said lower surface having a low pitch adjacent to the step. The closures are easy to apply and remove, and do not blow off unpredictably or uncontrollably under pressure.

摘要： The invention provides container closure assemblies, especially for carbonated beverage containers, comprising a container neck (10) and a closure (12). A first screw thread on one of the neck (10) and the closure (12) comprises one or more first thread segments (18), and a second screw thread on the other of the neck and closure comprises a plurality of second thread segments (20). The neck and closure are constructed with a pressure safety feature that blocks unscrewing of the closure, and provides for gas venting from inside the container, when the closure (12) is at an intermediate position on the neck (10). The gas venting means includes a recess (66) located between and circumferentially overlapping two of the second thread segments (20), to increase the cross-sectional area of the vent thread path (26) through which the pressurized gas escapes at the intermediate position.

摘要： The invention provides child-resistant closures comprising: an inner closure part (100) carrying an internal screw thread (106) for screw threaded engagement with the neck of a container; an outer closure part (200) retained on the inner closure part (100); a first set of castellations (126) on the inner part (100); a complementary second set of castellations (212) on the outer part (200); a set of resilient blades (216) on one of the inner or outer part to hold the inner and outer parts (100, 200) apart so that the castellations (126, 212) do not engage unless an axial compressive force is applied between the inner and outer parts; and ratchet projections (120) on the other of the inner or outer part adapted to engage the resilient blades (216) only when the outer part is rotated in the screwing-down direction. The improvements comprise means to reduce the transfer of unscrewing torque from the outer closure part (200) to the inner closure part (100) when a bending moment is applied between the inner and outer closure parts and the outer part (200) is rotated in an unscrewing direction. The preferred means include: (i) radial chamfering of one or both sets of castellations (126, 212); (ii) means to reduce rocking of the outer closure part on the inner closure part, especially a cylindrical projection (214) on one of the inner or outer part slidably received in a cylindrical socket (130) on the other of the inner or outer parts, the projection (214) and socket (130) being coaxial with the rotational axis of the closure; (iii) the provision of an integral reinforcing rib (220) on the resilient blades (216); and (iv) the provision of lubricant between abutting surfaces of the inner and outer closure parts.

摘要： L'invention se rapporte à un ensemble de fermeture de récipient comprenant un col (10) présentant une surface d'étanchéité externe radiale (20) et une fermeture correspondante (12) pourvue d'une surface d'étanchéité interne radiale (18) conçues pour venir se plaquer hermétiquement contre la surface d'étanchéité du col du récipient. Des éléments sont ménagés pour fixer la fermeture sur le col du récipient, ces éléments étant séparés des surfaces d'étanchéité (18, 20). Lorsque la fermeture est fixée au col du récipient, un jeu (24) est crée entre la surface externe du rebord et la surface interne de la fermeture. Le col du récipient est fermé hermétiquement par un joint sous forme de film (28).

摘要： A container closure comprising : a plastics inner cap (2) having a base portion (4) and a skirt portion (5), a thread (10) on the inside of the skirt portion, a first snap fitting element (11) on the outside of the skirt portion, and a tamper evident ring (6) formed integrally with the skirt portion and joined to an open end of the skirt portion by severable connections (20,21); a plastics overcap (3) having a base and a skirt portion (26) in mating engagement with the skirt portion of the cap and extending beyond the open end of the skirt portion of the cap to at least partially cover the tamper-evident ring, and a second snap fitting element (31) on the inside of the skirt that engages with the first snap fitting element on the inner cap skirt to resist separation of the overcap from the inner cap. Also provided is a closure assembly comprising a threaded container neck (1) and a container closure according to the invention.
