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 is provided and comprises a top plate and a sidewall depending therefrom. The interior of the sidewall has a screw thread formation comprising a plurality of thread segments. The thread segments collectively define an engagement surface for engagement with an external thread formation on an associated container. A notional helical top surface with a constant pitch extends along the formation, and at least some, but not all, of the segments include material offset from the notional helical top surface towards the top plate.

Abstract: A closure (10) for a container mouth, comprising a cap (15) and a retaining ring (20) for retaining the closure on a container mouth, a tether (45) is provided between the cap side wall and the retaining ring along the circumference of the cap, one end of the tether is fixedly connected to the side wall and the other end is fixedly connected to the retaining ring, in which the tether is connected to the cap by a root (30) and extends from the root in a clockwise direction.

Abstract: A closure 10 for a container, comprises a substantially circular base 20, a skirt 30 extending from the periphery thereof, a bore seal 50 in the form of an annulus and a rib 70 lying on the surface of the base 20 in a substantially radial direction and in contact with the radially inner surface of the bore seal 50 at one end for transferring any movement of the centre of the base 20, relative to the skirt 30, to the bore seal 50 such that the bore seal 50 is pulled radially inward to allow venting of excess pressure within the container, wherein the end of the rib 70 in contact with the radially inner surface of the bore seal 50 is substantially thinner, in a plane parallel to the base 20, than the other end of the rib 70.

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, in increase to 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.
