Description

Cork.

Object of the invention

The present invention relates to a plug of cork.

Background of the invention

At present the caps for sparkling wines they are manufactured by means of an agglomerated cork body, with one or two lower discs of natural cork.

The agglomerated cork is made with a granulate whose grain size is between 4.75 to 2.72 mm

The current problem is that some are broken discs at the time of bottling, due to the speed with which Bottling machines operate.

These discs are the lower ones, that is, the ones that  They keep in touch with the wine.

In addition, there is a growing concern for the tampon taste as a result of the sparkling wines that elaborate at present are largely "brut", and so Both very sensitive to any variation of flavor.

This plug taste is a consequence of a fungus, the " Armillaria mellea ", which affects some pieces of cork.

Description of the invention

The cork stopper of the invention has a simple and economic constitution through which the inconveniences described.

According to the invention, the cap is constituted by a particle size agglomerated cork body usual.

This body incorporates at its lower end a microgranulated cork disk, based on granules of considerably smaller size than the granulate considered normal for this use, and from various sources. This disc, which is the one in contact with the wine, due to this microgranulated configuration does not break during bottling, even in fast mechanical bottling. In addition, due to the different composition of the cork granules, their colonization by the fungus " armillaria menea " is avoided.

Optionally the cap can incorporate another lower disc of natural cork, sandwiched between the body of the stopper and lower disc of microgranulated cork.

Brief description of the drawings

Figure 1 shows a section of the cap of Cork of the invention with a single lower disc.

Figure 2 shows a section of the cap of Cork of the invention with two lower discs.

Description of a practical embodiment of the invention

The plug 1 of the invention is constituted by a conventional agglomerated cork body 2, that is, whose granule size is between 4.75 and 2.72 mm.

By its lower and inner end to the bottle body 2 fixes a disc 3 of microgranulated cork, that is, of agglomerated cork of granule size less than 1 mm, whose granules also have various provenances.

This disc does not break during the mechanical bottling process nor, since it is a cork base of different origins, it is capable of raising the " armillaria menea " fungus, which spoils the taste of the wines by giving them a tampon taste.

Optionally, as seen in Figure 2, the stopper can incorporate another lower disc 4 sandwiched between the body 2 and the lower disk 3. In this case, disk 4 is constituted in natural cork.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
