<p>The aim of the invention is to develop a simple structural design for a closing device, which is easily and reliably produced, assembled prevents the bottle from becoming refilled and is provided with more effective warnings of visual indication which clearly and irreversibly show that the bottle has been already opened. The inventive bottle closing device comprises a screw cap screwed on an external sleeve which is connected to an internal sleeve by means or ribs in such a way as to form through channels, an elastic element with a through hole and a metal shell, wherein a chamfered edge is made on the outer surface of the screw cap in the top part thereof, a ring-shaped indicating belt in the form of a cone is made on the lower part of the cap in such a way that it is projected outside thereof, an annular flaxible sealing flange, inside which fixing elements are radially located, is made on the end inner surface of the screw cap and at least two stops for fixing the elastic element in an axial direction are made on the inner surface of the external sleeve.</p> |
