A device for closing of bottles contains a monolithic cork formed by cylindrical skirt, internal diameter of which is equal to the external diameter of bottle neck, annular bottom and internal centralized cylindrical bushing, and detachable cap. A concentric O-ring with the wall conical in the section is made on the internal surface of the bottom, outside diameter of which is equal to the inside diameter of the bottle neck. The end of internal centralized cylindrical bushing is equipped with the membrane with circular line weakened due to the decrease of the thickness of material strength. In the upper part of the cork on the external surface of cylindrical skirt an annular flange is executed. The detachable cap is made in the form of a plate cover with cylindrical ring, inside diameter of which is equal to the outside diameter of the cork. The lower part is concave centripetally ensuring the engagement with the flange of the cork according to the principle of locking tooth.
