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 moveable, 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 closure for a container. The closure comprises an end panel, a sidewall depending from the end panel and having an inwardly directed curl, and a sealing compound extending down the inner surface of the sidewall. A plurality of ribs are formed in the sealing compound, spaced apart around the circumference of the sidewall, each rib extending down the sidewall and projecting radially inwardly.

A tamper-resistant lid assembly for dispensing a premeasured amount of liquid from a beverage container and a method of providing a tamper-resistant lid assembly for use in dispensing a premeasured amount of liquid. The assembly includes a cup and a ring that are secured to one another using a snap-fit connection, as well as a lockable connection enabled by a selectively twistable rotation of the cup and the ring once the snap-fit connection is established.

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. The closure includes an upper wall defining an opening and a cylindrical snap on pipe 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 and a guidance recess. The resistance recess and the guidance recess accommodate a forcing element on a shoulder of the bottle and permit unscrewing of the closure

What is proposed is a closure unit consisting of a glass container (50) with external, circumferentially offset threaded elements (54, 55) on a container neck (52) of the glass container, and a closure cover made of sheet metal, wherein the closure cover (1, 2) has an encircling plastics layer (30; 30h, 30v) on the inside of the cover. The closure cover is pressed onto the container neck (52) and can be opened with a rotational movement via the threaded elements (54, 55) and a vertical section (30v) of the plastics layer. The container neck (52) has a horizontal end surface (52a) on which a horizontal section (30h) of the plastics layer rests under pressure in a sealing manner. A central region (11) of the closure cover passes with an adjoining, circumferentially oriented transition zone (11a, 11b, 11c) into an axially downwardly projecting skirt section (12) which ends in a roll-up region (21a, 21; 22). The plastics layer (30; 30h, 30v) is arranged on the inside of the cover in a manner adhering to the transition zone (11a, 11b, 11c) and the skirt section (12). An axial extent (h.sub.0) of the skirt section (12) and a radial dimension (b52) of the horizontally oriented end surface (52a) of the container neck (52) form a first ratio (v.sub.1) which is smaller than three.
