Description

BOTTLE SCREW CAP WITH REPLACEABLE SEAL

The subject of the invention

The object of the invention is a bottle screw cap with an exchangeable seal, which consists of a rigid cylindrical, partially hollowed body of the stopper and a softer, partially malleable sealing plate, which can be replaced as many times as desired and in this way, after each replacement, allows the appropriate degree of sealing of the liquid in the bottle at the same time the passage of excess gases. The stopper is a version of the classic single-use screw stopper, with the difference that the replacement of a relatively small and thus cheap sealing element enables the complete restoration of the original sealing ability of the stopper, thereby making it reusable.

Technical problem

Classic screw caps are used for many types of alcoholic and non-alcoholic beverages. Classic cork stoppers can also be used for wines, in terms of sealing quality and gas passage, but screw-on stoppers are more suitable due to repeated opening.

The problem arises with those wines where part of the ripening cycle takes place even when the wine is already bottled. In the case of so-called fresh wines, the screw cap seals more adequately and thus preserves freshness, which is expressed in carbon dioxide, which is not produced in quantities that would cause visible bubbles, but in almost imperceptible quantities, which is desirable for fresh wines. Such properties of permeability and at the same time the naturalness of the material can only be provided by a cork tile or a disc with horizontal pores.

In addition, for wines, screw caps are also more practical and reliable, as they allow multiple checks of the edibility and quality of the wine during maturation by opening the bottle, which cannot be done with classic corks without visible damage to the cork and its entire replacement with a new one.

The technical problem solved by the screw cap according to the invention is how to enable an adequate level of sealing of the bottled liquid while at the same time adequate permeability of the resulting gases, how to enable the restoration of the cork by changing its cheaper part and how to test the already bottled wine without visible aesthetic and physical damage to the cork.

Known state of the art

Cork stoppers in the form of a plug are mostly used for finer drinks. The latter maintain the opening ritual for wines of a higher price class, which is important for the discerning guest. A cheaper version of this type of stopper are plastic or partially rubberized stoppers, the advantage of which is greater durability and less deformation when reused, but they do not allow gas permeability.

For drinks and other liquids, which are dosed until the bottle is empty several times in a row and need intermediate sealing, screw caps are used, which are mostly made of plastic or aluminum housing and softer inner sealing surface made of artificial materials.

For other types of drinks, a metal, so-called Krono stopper is used, which is removed from the bottle with an opener and is intended for one-time use, as it deforms when opened.

A more advanced type of cork is a diam cork, of which there are several types and they are distinguished by this. what air permeability they allow. For greater air permeability, diam stoppers marked 10 are used, in which the permeability is closer to the thread than the permeability of ordinary cork. Diam stoppers are made of purified microgranules, which cannot be infected with bacteria and cannot smell of mold or fungus.

For most wines, cork is still the best choice, as under it the wine ripens faster due to greater microoxidation.

Solving a technical problem

The bottle screw cap 1 consists of a cylindrical rigid housing 2, which is hollowed out in part of its height. The blind hole 5 shares the axis 9 with the housing 2. The thread 4 runs along the inner circumference of the blind hole 5, which, depending on the bottle 8, can be trapezoidal, sawtooth or round. The internal thread 4 must be made in such a tolerance with respect to the external thread 7 of the bottle 8 that it offers a sufficiently large gas permeability from the inside of the bottle 8 to the outside space.

The internal thread 4 runs from the mouth of the blind hole 5 into its interior. At the end of the blind hole 5 there is a cylindrical chamber 10 into which a cork disk 3 is inserted.

The cork disc 3 has the same diameter as the diameter of the cylindrical chamber 10, or is smaller than it, but larger than the inner diameter of the thread 4, which ensures the interchangeability of the cork disc 3, and at the same time it is prevented from falling out automatically.

Both base surfaces of the disc 3 are flat, or the surface directed towards the mouth of the blind hole 5 is slightly convex, convex, for better fitting to the annular mouth 6 of the bottle neck 8.

The cork disk 3 is partially permeable to gases, and threads 4 and 7, when joined together, must also provide the same or greater permeability with their measurement tolerance.

The wooden cylindrical body 2 of the bottle screw cap 1 is intended for repeated use, and the cork disk 3 is changed every time the bottle is refilled, since the organic material loses part of its physical properties, such as gas permeability, sealing efficiency, due to chemical processes and compression between two solid surfaces bottled liquids, and the required biological properties are also lost, as the cork eventually no longer meets the prescribed hygiene standards due to mould.

The height of the cylindrical wooden case 2 is between 20 and 50 mm, preferably 35 mm, and its diameter is between 30 and 50 mm, preferably 40 mm. The thickness of the threaded wall of the thread 4 is from 5 to 10 mm, preferably 7 mm. The length of the thread 4 is from 15 to 45 mm, preferably 25 mm. The height of the cylindrical chamber 10 is from 4 to 15 mm, preferably 8 mm, and its diameter is 0.1 to 3 mm, preferably 1 mm larger than the inner diameter of the thread 4. The height of the cork disc 3 is from 4 to 15 mm, preferably 7 .5 mm and is smaller than the height of the chamber 10 by 0.1 mm to 2 mm, preferably 0.5 mm. The diameter of the cork disc 3 is smaller than the diameter of the chamber 10 by 0.1 to 1 mm, preferably 0.5 mm.

The shell of the cylindrical wooden case 2 can be rough in the direction of the axis of the cylinder 9, but it can also be shaped as desired and finished at one or both ends of the cylinder with a sharp, cut, rounded, domed, concave, partially rounded or otherwise shaped edge, which affects aesthetic aspect of the product and hand grip, but has no influence on its technical characteristics.

The wooden cylindrical housing 2 is preferably made from the wood of harder deciduous tree species, such as beech or oak, and can be oiled on the outside or coated with some other coating that meets the sanitary standards for food contact.

The wooden cylindrical housing 2 can be stamped, engraved, or printed on the upper surface or on the cylinder jacket for the purposes of recognition, differentiation, promotion and markings on the suitability of the product.

The essence of the invention is explained in more detail with a description of the implementation example with reference to the attached drawings, which show the following:
