Abstract: A device for stoppering a container and drawing off a fluid includes a fixed piece, fixed to the container, with a lateral fluid output opening and a passage that allows air to enter. Another, movable piece includes a tube with a lateral fluid output opening. This tube can move in rotation inside the fixed piece and also in axial translation between a maximum “pushed-in” position and an extracted position so that lateral openings can be brought into coincidence through rotating the movable piece. The movable piece has an internal skirt enabling the channeling of fluid toward the output opening to prevent leakage through the passage for the entry of air. The fixed piece includes a guide for displacing the movable piece with respect to the fixed piece from the maximum “pushed-in” position to the extracted position that displays a coincidence of the openings.

Abstract: The device comprises: a piece fixed to the container, having a lateral fluid output opening and a passage allowing the entry of air; a movable piece comprising a tube having a lateral fluid output opening, the tube being movable rotationally in the fixed piece and in axial translation between a maximum pushing-in position and an extraction position where the lateral openings can be brought into coincidence by rotation of the movable piece. The movable piece comprises an internal skirt making it possible to channel the fluid towards the output opening in order to prevent leakages through the air entry passage. The fixed piece comprises means for guiding the displacement of the movable piece with respect to the fixed piece from the maximum pushing-in position to the extraction position with coincidence of the openings.
