The invention relates to a container made of glass or hard plastic having a container neck (52) with a plurality of external thread elements (53, 54, 55, 56, 57, 58), which are offset circumferentially relative to one another, as thread segments. The container can be closed by means of the thread segments by a closure cap made of metal sheet, wherein the closure cap (1, 2) has a circumferential plastic layer (30;30h,30v) on the inside of the cap and on the rim of the cap which has a sealing and retaining action. The closure cap can be pressed onto the container neck (52) and over the thread elements (53, 54, 55, . . . ) during closure and a vertical portion (30v) of the plastic layer can be opened with a rotary movement relative to the thread segments (53, 54, 55, . . . ). The container neck (52) has an upper horizontal end face (52a) as an annular surface which is adapted and suitable to be pressed into a horizontal portion (30 h) of the plastic layer (30;30h,30v) of the closure cap (1.2) under pressure and to produce a seal under pressure. An axial spacing (h54) is defined which extends between axially upper ends (53a, 54a, 55a, 56a, 57a) of the thread segments (53, 54, 55, 56, 57, 58) and a horizontal plane (E52a) through the horizontally oriented end face (52a) of the container neck (52) of the glass container (50). An annular width (b52) of the upper horizontal end face (52a) is defined as an annular surface. A ratio of the axial spacing (h54) to the annular width (b52) is less than 1.35.

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.

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.

The invention relates to a polymer compound for a PVC-free sealing insert for twist crowns, wherein the Shore A hardness of the polymer compound is between 50 and 90 and in the compressive deformation test analogous to ASTM D395-97 Method B at 70 DEG. C. the polymer compound exhibits a compression set of 30-90%.

Drinking bottle closures include a sealing portion, an upper side that may bear indicia, and a retained magnet. The magnet may be retained in a cavity of the closure separated from the sealing portion by a seamless barrier. The sealing portion may include a frictionally retained male tapered plug or a radially compressible, gripping female cap liner to fit one or multiple bottle opening sizes. In a method of use, the cap may be retained on a magnetically attracted surface until used to close and identify a drinking bottle. The magnetically attracted surface may be a plate connected to a mount for connecting the magnetic surface to a non-magnetic surface.
