Abstract: A tamper-evident closure comprising a cap and a retaining ring, the retaining ring is connected to the sidewall by a plurality of bridges, at least one of the bridges is frangible and at least one of the bridges is non-frangible whereby to form a link between the ring and the sidewall.

Abstract: A closure for a container is provided. The closure comprises a cap and a retaining ring arranged under the cap for retaining the closure on the container in use. The cap and ring are joined by a pair of connecting arms. A first arm is non-frangibly connected to the cap at a cap tether end and circumferentially anticlockwise therefrom is non-frangibly connected to the ring at a ring root end. A second arm is non-frangibly connected to the cap at a cap tether end and circumferentially clockwise therefrom is non-frangibly connected to the ring at a ring root end. The cap can be tilted away from the ring with the arms providing a hinge-like function, and each of the arms twists between its cap tether end and its ring root end, whereby tension is generated in the arms.

Abstract: A closure assembly has a closure cap (2) adapted to be fitted to the neck of container to close the container. The cap (2) has an upper wall (4) and a cylindrical skirt (5) depending therefrom. A reservoir (7) is formed on the underside of the upper wall (4) radially within the skirt (5) and has a dispensing opening (9). A closing member (3) is fitted into the closure cap (2) to close the dispensing opening in the reservoir. When the closure cap (2) is removed from the container, the closing member (3) remains held within the neck of the container and is separated from the closure cap so that the dispensing opening is opened and material contained therein is dispensed into the container. The closure cap is provided with sealing means for directly sealing against the neck of a container such as an annular wall (12) extendin downwardly from the underside of the upper wall of the closure cap (2) to fit sealingly into the neck of the container.

Abstract: A closure for a container comprises a circular base, a skirt extending from the periphery of the base, an outer seal, a plug seal in the form of an annulus, and at least one rib lying on the surface of the base in a substantially radial direction and in contact with the radially inner surface of the plug seal at one end for transferring any movement of the base, relative to the skirt, to the plug seal such that the plug seal is pulled radially inward to allow venting of excess pressure within the container. The outer seal of the closure comprises at least one deformation portion which partially interrupts the sealing effect of the outer seal in case overpressure occurs.

Abstract: A closure assembly comprising a closure spout adapted to be fitted to the neck of a container and a closure cap. The closure spout comprises a dispensing opening. The closure cap comprises an upper wall and a skirt depending therefrom, adapted to be fitted to the closure spout to close the container, especially for use on pressurized containers such as carbonated beverage containers. At least one substantially continuous second retaining arrangement on said closure spout has one ore more elongate second retaining segments. The lower second retaining surface has no pitch or at least a relatively lower pitch in a first region, a relatively higher pitch in a second region displaced from the first region in an unscrewing direction, and no pitch or at least a relatively lower pitch in a third region displaced from said second region in an unscrewing direction.

Abstract: A plastic closure for a container is provided. The closure includes a top plate with a side skirt depending from the periphery thereof. A sealing strip depends from the top plate and is adapted to sealingly engage a container neck finish. The closure also comprises an abutment member including a guide surface for guiding the sealing strip towards the neck finish as the closure is applied, to increase the strength of the seal. The guide surface includes a guide member that projects from the abutment member, thereby minimizing friction between the strip and the abutment member. The sealing strip is inclined radially towards the neck finish to improve the sealing effect.

Abstract: For improving the venting behavior of containers with beverages containing carbon dioxide, a container finish (1) and a closure (11) is provided with a twin-start thread. The thread comprises in each case two threads (3, 13) which extend over an angle of 240.degree. to less than 360.degree., preferably 280.degree., and which are arranged so as to be displaced at 180.degree.. In this way, initial or first sections (5), in which the threads (3) overlap each other vertically, are formed on the outside surface (2) of the container finish (1), as well as second sections (6) in which, vertically, only one thread (3) is arranged. On the inside surface (12) of the closure (11), initial or first sections (15) are formed in which the threads (13) overlap each other vertically, as well as second sections (16) in which, vertically, only one thread (13) is arranged. In each of the sections (5, 6, 15, 16), at least one venting recess (4, 14) is arranged per thread, said venting recess interrupting the threads (3, 13).

Abstract: A compression failure resistant tamper evident bottle cap includes a skirt with a lower edge, and a tamper-evident band formed integrally with the skirt and having structure for engaging beneath a retaining flange on the bottle so as to prevent subsequent withdrawal of the band. Frangible bridges connect the band to the lower edge of the skirt. To prevent destruction of the bridges as the cap is forced onto the bottle during installation, the skirt has one or more tabs or the like, extending downward over a portion of the band, for preventing undue diametral expansion of the tamper evident band as it passes over the retaining flange.
