Sealing system for prevention from repeated filling of bottle with a shoulder on the neck contains means for discharge of content of bottle, housing of which is located on the neck of the bottle, cover, which covers the upper part of the housing of means for discharge and cylindrical locking bushingconnected with it with the help of the screw connection, which covers the neck of bottle and the lower part of the housing of means for discharge, tear-off ring-shaped strip, which connects cover and locking bushing. The housing of means for the discharge is executed in the form of cylindrical tube. The lower part of cylindrical tube covers the shoulder of bottle and its neck in the section under the shoulder. Tapered protrusions in longitudinal section are executed on the internal surface of tube in the section under the shoulder along the generatrix, around which U-shaped cuts are located, between which from the outer side of the tube segmental cuts are executed in such a manner that the area of tube in the cross section has the shape of polyhedron, and at radial deformation the perimeter of locking bushing in the cross section throughout the center line obtained as a result of its deformation in case of interaction with the protrusions of tube, in fact, does not exceed the length of the circle of locking bushing in the cross section throughout the center line up to the said deformation. The flange is executed on the external surface of the lower part of the cover, and hooks are executed on the internal surface of tear-off ring-shaped strip intended for engagement with the cover flange. On the lower edge of tear-off ring-shaped strip with the a shift relative to hooks the cross connections are rigidly fixed by their first ends, second ends of which are rigidly fixed on the upper edge of locking bushing with a shift relative to the place of fastening of first ends.
