Abstract:
The invention relates to bottle closures containing a valuable liquid, protecting against refilling and signalling a first opening of the bottle. The inventive protective plug comprises a decorative cover provided with a detachable element, a closing sleeve and a drain unit. Said drain unit is embodied in the form of a drain bush provided with an annular threaded boss on which a lid having a pipe for evacuating the liquid and nicks formed on the external surface thereof is arranged. The detachable element is disposed on the end part of the decorative cover. The closing sleeve is provided with nicks on the interior surface thereof and arranged inside the decorative cover in such a way that the nicks thereof are reciprocally rotatable with respect to the drain bush and can interact with the nicks, thereby providing said lid with an axial motion and detaching it by the branch of the detachable element. Said invention makes it possible to improve the use of the lid.
