Description

 The invention relates to the field of detachable joints of parts of sealed packages of liquids and aerosols, bottles and cans having a groove in the neck.

 Known tight connection of the lid with a glass jar and the connection of pipes with a sealing element. The specified element has torsion-fixing properties and can serve for detachable tight joints that carry a small power load. In addition, it is difficult to manufacture in its shape and its element (springs) reinforcing it, and with great effort the connector is connected, which reduces the consumer properties of the connection.

 Known torsion-jamming connection, adopted as a prototype, contains at least one torsion ring installed between a smooth surface and the surface of the neck of the container, made with a groove (see RU 2103577 C1, 1988).

 However, it cannot be used for bottles and cans with a groove.

 An object of the invention is to expand the scope of use of torsion joints with improved consumer characteristics of glass containers.

 The technical result is achieved by the fact that the torsion ring is in contact with the elastic ring installed in the groove of the neck of the glass container with the formation of a smooth surface.

 The drawings give an example implementation of the invention, for example, for a refillable cap of a beer bottle.

 FIG. 1 - axial section of the neck of a bottle with a reusable cap.

 FIG. 2 is a preferred embodiment of a torsion ring in plan view.

 FIG. 3 - an element of the ridge of the ring in axial section on an enlarged scale.

 The compound of FIG. 1 contains a cap 1, preferably made of plastic, a gasket 2, the neck of a container (bottle) 3 with a groove in which an elastic ring 4 is mounted to form a smooth surface. Between the ring 4 and the smooth surface of the cap is installed at least one torsion ring 5, molded from plastic (see all figures). The ring can be made of a thin metal strip (aluminum foil). When forming a ridge by stamping from a strip along the profile of a “mouse tooth”, see FIG. 3, with a single-tooth tool, the strip will be twisted into a split ring of the desired diameter. In the cap 1 with the gasket 2 and in the cap of the ring 5 are installed with deformation of the gasket 1 to ensure tightness. In this case, the internal wedging surface is turned out over the tops of the zig. The reverse movement does not occur due to jamming of the torsion ring 5 between the involved surfaces.

 Removing the cap occurs during rotational or circular oscillatory movements and axial manual load applied in the opening direction.

 When implementing the invention, consumer characteristics, for example, beer bottles, will improve. There is no need for an opening tool that the consumer does not carry in his pocket. The contents of the bottle can be consumed partially and again hermetically sealed. The bottle together with the cap can be returned to the manufacturer. There will be no broken bottles or spoiled surfaces on which the bottles open. There will also be no abandoned caps. It is not necessary to purchase a canopy tool. Banks and lids, for example, metal, will be reusable. It is impractical to produce plastic caps; moreover, polyethylene reacts with many products, which leads to spoilage of the product, and in most cases the consumer does not know about it. The quality guarantee of the contents of the containers is provided by a glued excise tape (not shown in the drawing).

 To increase the reliable connection on the glass container (neck) and even without a groove, it is necessary to wear elastic rings, for example from rubber, to increase the angle of jamming. Rings are best glued. It is also possible to apply an adhesive layer without gaskets.

Claims (1)

 Torsion-jamming connection containing at least one torsion ring installed between a smooth surface and the surface of the neck of the tank made with a groove, characterized in that an elastic ring is installed in the groove of the neck of the tank to form a smooth surface for installing the said torsion ring.
