Abstract
Anti-filling device to be attached to the neck of a bottle to be closed by a sealing cap, including attachment means for attachment to the bottleneck, a chamber including a lower lip surrounding a lower orifice and confining a moveable part which forms a valve in conjunction with the lower lip, and an axial distribution duct. The device further includes a moveable axial rod, secured to the anti-filling device, the axial movement of which relative to the device is limited between a low position and a high position, and at least one stopper which is in engagement with the moveable axial rod such that, when the moveable axial rod is located in the low position, the stopper shuts an orifice which is arranged in the chamber. The low position is imposed by a projection attached to the cap, which comes into contact with the moveable axial rod when the cap is attached to the bottleneck.
