A closure for a bottle. The closure includes a spout neck (200) attached to the bottle and a cap (300) rotatably positioned on the spout neck. The spout neck may have a sealing lip (240) and the cap may have an internal vent and an internal body portion. The sealing lip (240) of the spout neck and the body portion of the cap align to seal the bottle when the cap is in a first position. The sealing lip of the spout neck and the circular vent (470) of the cap align so as to vent the bottle when the cap is turned to a second position.

Cette invention concerne un bouchon de bouteille comprenant une goulotte solidaire de la bouteille et un bouchon monté rotatif sur la goulotte. La goulotte peut comporter une lèvre d'étanchéité, et le bouchon un évent et une partie corps intérieurs. La lèvre d'étanchéité de la goulotte et la partie corps du bouchon s'alignent l'une sur l'autre et obturent la bouteille lorsque le bouchon se trouve sur une première position. La lèvre d'étanchéité de la goulette et l'évent du bouchon s'alignent l'une sur l'autre et mettent la bouteille en communication avec l'atmosphère lorsque l'on tourne le bouchon sur une seconde position.
