A snap-on/twist off closure (22), a package comprising the closure, e.g., a bottle in combination with the closure is disclosed. The closure includes an upper wall defining an opening and a cylindrical snap on pipe (30) depending from the upper wall. The pipe includes threads designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess (42) and a guidance recess (70). A bottom rim of the pipe, the resistance recess and the guidance recess are in contact with a forcing element (50) on a shoulder of the bottle and guide the closure into positions permitting unscrewing of the closure.

An improved snap-on/twist off closure which is very durable. The invention is also directed to a package comprising the closure, e.g., a bottle in combination with the closure.

A bottle assembly is provided including a bottle having an end portion with a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided including a base member and a sealing member. The sealing member is movable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.

A container includes a container body; and a cap that locks onto the container body, the container body and the cap being locked by putting the cap on the container body. The cap includes a cap body, a cover cap being held on the cap body so as to be displaceable and rotatable, and an urging portion that upwardly urges the cover cap. When a rotational force is applied to the cover cap being downwardly pressed, the cap body is displaced in conjunction with the cover cap, so that locking between the cap body and the container body is released, and in a state where the cover cap is not downwardly pressed, the cap body is not displaced in conjunction with the cover cap even when a rotational force is applied to the cover cap, so that locking between the cap body and the container body is not released.
