Abstract: A pouring stopper to be mounted on a bottle has an inlet gasket, an outlet gasket and an air admission valve. The mentioned gaskets are controlled by a magnetizable rod, which, together with a coil, is incorporated in an area, such as a liquid chamber, in the pouring stopper. Another housing contains a battery and electronics. With the pouring stopper according to the invention, a very compact pouring stopper is achieved, which may be used both handheld and in a bottle holder. Further, it is possible to dose on the basis of a volume or on the basis of a time interval. Finally, it is possible to monitor the pouring from the pouring stopper closely, if its electronics are provided with a transmitter and a receiver which are capable of communicating wirelessly with a PC. This provides the possibility of having full control of the pouring operations, in particular if the pouring stopper is sealed to the bottle.
