I Hitherto a bottle closure for alcoholic liquors, particularly of a high alcohol content, is a metal cap in a form of a thin-walled cylinder closed from the top, which has a circumferential incision on a side sur- face.

A cap during a closing operation of a filled bottle, after placing a sealing therein, is overlaid from the top onto the screwed bottle neck, and subjected to the operation of a rotational crimping device which reduces a cap on a screwed neck, forming a closely adherent screw joint.

While opening the bottle, the upper part of a closure is undone which operation causes breaking of a circumferential incision, being a seal.

Such closure can not be reused in its original form and it makes unable refilling the bottle with a content different than an original and legal alcoholic product.

The closure known from the prior art has a marking of a pro- ducer laid over the top of a cap. Since in the commodity circulation conditions a paper label band of an exercise duty is stuck on the known bottle closure, mostly the mentioned marking is not visible to the buyer. Furthermore, a label band of an exercise duty made of a paper band is undurable and it easily gets unstuck, which is often in collision with a decoration of a liquor bottle.

Some producers of strong alcoholic liquors use to place their marking in a form of a hologram, which is stuck on the side wall of a bottle preventing the adulteration. However, since bottles are mainly returnable packages and the labels, holograms and an applied glue are of a high quality and of a long term durability, such bottles can be eas- ily filed with a liquor of an unknown origin and closed with a bottle closure known from the prior art., giving a view of an authenticity to the buyers.

The bottle closure according to the utility model enables to avoid the mentioned hazard and inconveniences.

A bottle closure according to the invention is a metal cap in a form of a closed from a top with a bottom, thin-walled, metal cylinder, which has a circumferential incision on a side surface and circumferentially formed pressed reinforcements, which on its outer surface of the top and on its side wall has a holographic marking of an exercise duty and a producer.

A bottle closure according to the invention relates some func- tions therein, where the most important are the exercise duty mark- ing, the producer indication, and the protection of a content. While opening, the circumferential incision must be torn and the bottle clo- sure can not be reused.

The bottle closure according to the invention enables to eliminate the use of undurable and offensive paper bands for an exercise duty mark- ing, making at the same unable a falsification of the marking and an illegal filling of a bottle.

The bottle closure according to the invention is presented on the en- closed drawing, showing a cross-section thereof.

The bottle closure is a metal cap 1 in a form of a closed from a top with a bottom 2, thin-walled metal cylinder, which has a circumferential incision 4 on a side surface 3 and circumferentially formed pressed stiffening reinforcements. On the outer surface of the top bottom 2 and on a side wall 3 the areas A and B are located, wherein a holographic markings of an exercise duty and a producer indication are placed.
