Abstract: A container a side surface and a rim that defines an opening and an axis; a closure for the container; the container and closure having cooperating threads to move the closure axially as it is rotated; the closure having a seal against the side surface of the container; the thread portions of the container and closure are configured such that, as the closure rotates relative to the container, the seal moves parallel to the axis contacting three regions on the side surface of the container: a first region, configured such that, as the seal is moved across the region, the seal changes between states in which it is uncompressed and compressed between the container and closure; a second region, where the fluid bypasses part of the seal; and a third region where the seal forms a fluid-tight seal between the side surface and the closure.

Abstract: A closure for a container is provided. The container has a side surface and a rim. The rim defines an opening and an opening axis perpendicular to the opening. The closure has a top portion for covering the opening; and a skirt portion, connected to the top portion, that surrounds a region of the side surface when the closure is connected to the container. The skirt portion has thread portions that cooperate with thread portions on the side surface to define movement of the closure relative the container in a direction parallel to the opening axis as the closure rotates about the opening axis relative to the container. The closure includes a liner extend across the top portion of the closure and at least partway across the skirt portion away from the top portion. The liner seals the opening of a container when the closure is connected to the container.

Abstract: A beverage container (1) comprises a container body (3) including an opening, a cap (5) to close the opening, and a collar (7), mountable on the container body (3). The cap (5) and the collar (7) include cooperating securement means (19, 21) by which the cap (5) may be secured to the collar (7), thereby securing the cap (5) to the container body (3) when the collar (7) is mounted on the container body (3). The cap (5), the collar (7) and the container body (3) are configured such that removal of the cap (5) from the container body (3) causes removal of the collar (7) from the container body (3).

Abstract: A beverage container (1) comprises a container body (3) including an opening and a cap (5) to close the opening, the cap (5) or the container body (3) including one or more bayonet threads (57), and the container body (3) or the cap (5) respectively including one or more protrusions (19) arranged to engage with a respective bayonet thread (57) to secure the cap (5) to the container body (3). At least one of the bayonet threads (57) includes one or more stop members arranged to retain the, or each, protrusion (19) substantially fully engaged with the bayonet thread (57) such that the opening is substantially fully closed by the cap (5), until a releasing torque sufficient to overcome the retention is applied to the container.
