A leakproof cap of a soft water bottle and a water bottle are disclosed. The leakproof cap includes a cap body having an installation cavity with a screw thread circumferentially arranged on a side of the installation cavity, and a sealing member annularly arranged on another side of the installation cavity that is opposite to the screw thread at a predetermined distance. The sealing member is an elastic sealing member and a side of the sealing member facing the screw thread has a plurality of sealing rings. The sealing rings are arranged concentrically and evenly, and a sealing cavity is formed between adjacent sealing rings. When the bottle opening deforms following the bottle body, the sealing member adapts to the deformation and blocks the liquid through the plurality of sealing rings.

A cap assembly for a container that includes an outer-shell and an inner-element that is received within the outer shell. The outer shell includes a recess on the interior surface of a top portion and the recess includes a top flange section that restricts the opening. The recess receives a complementary end wall that extends from the inner-element and which has a lip that mechanically locks within the recess thereby keeping the shell and liner together. In embodiments a clutch plate is positioned between the shell and liner.

Described herein is a closing device including a closing element, a sealing element and a closing cap. The closing element is connectable at least form-fitted or force-fitted with a neck of a container. The closing device can be brought in a closed state, in which the closing cap closes output opening, and can be brought in an opened state, in which the output opening is released.

A cap for a squeeze bottle that is simply constructed, easily manufactured, simple to assemble and easily reassembled. The cap includes three components, a rounded lid with a slot, a nozzle with a near spherical base and an extended cone portion, and a gasket with a top, bottom and side walls to form a pocket. The user may insert and remove the nozzle from the pocket by pushing and pulling, respectively, on the stem.

A canister includes a container and a closure. The container is formed to include a product-storage region and an open mouth that opens into the product-storage region. The closure is configured to couple to the container to close the open mouth.

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 cap assembly for a container that includes an outer-shell and an inner-element that is received within the outer shell. The outer shell includes a recess on the interior surface of a top portion and the recess includes a top flange section that restricts the opening. The recess receives a complementary end wall that extends from the inner-element and which has a lip that mechanically locks within the recess thereby keeping the shell and liner together. In embodiments a clutch plate is positioned between the shell and liner.

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.

A leakproof cap of a soft water bottle and a water bottle are disclosed. The leakproof cap includes a cap body having an installation cavity with a screw thread circumferentially arranged on a side of the installation cavity, and a sealing member annularly arranged on another side of the installation cavity that is opposite to the screw thread at a predetermined distance. The sealing member is an elastic sealing member and a side of the sealing member facing the screw thread has a plurality of sealing rings. The sealing rings are arranged concentrically and evenly, and a sealing cavity is formed between adjacent sealing rings. When the bottle opening deforms following the bottle body, the sealing member adapts to the deformation and blocks the liquid through the plurality of sealing rings.

A container comprising: a container body that includes a wall portion separating inside and outside and is formed of a long-fiber-reinforced silicon-carbide composite material obtained by combining monofilaments of silicon carbide with a silicon carbide matrix, the wall portion having a thickness equal to a specific dimension; and a lid configured to close an opening of the container body, formed of a material containing at least silicon carbide, and equipped with such a wall portion separating inside and outside that thickness is within a range of 1 to 3 times the specific dimension.
