ABSTRACT:
An annular lock stopper for closing an aperture of a bottle having a neck with an inner wall, an upper edge which delimits the aperture, and an outer recess situated below the upper edge on an outer wall. The annular lock stopper includes a stopper part and a ring part. The stopper part includes a central stem for insertion into the neck of the bottle, an upper part, fixed to the central stem, and an outer part, depending from the upper part and arranged to embrace the outer surface of the neck of the bottle when the stopper part is in the inserted position, the outer part having a lower end portion comprising a widening arranged to fit into the outer recess of the neck of the bottle when the stopper part is in the inserted position. The ring part is attached to the stopper part by frangible connection disposed between a lower portion of the ring part and an upper portion of the stopper part, the ring part having an inner diameter such that, once the stopper part is in the inserted position and once the frangible connection means is broken, the ring part is displaceable in a first direction to a closed position in which the ring part surrounds and embraces the outer part of the stopper part.
