Abstract: A system for dispensing a liquid from a bottle 13 comprises an assembly 17, 18 and a stopper 19 to be introduced into a bottleneck, which stopper can be separated from the assembly. The stopper 19 comprises a liquid dispensing pipe 14, 16 with a electromagnetic valve 15 and a gas path 12 having a check valve 11 therein. The assembly comprises a solenoid 10 and a tank 1 containing gas for driving the liquid from the bottle. The tank is connected via a further electromagnetic valve 3 to gas pipes 8 and 9. The stopper which closes off the bottle can be connected to the assembly such that gas pipe 9 connects with check valve 12 and solenoid 10 surrounds electromagnetic valve 15. By actuating programmable button switch 4 both electromagnetic valves 3, 15 open for a preset time so that a metered quantity of liquid is dispensed from the bottle. Alternatively, another button switch 5 allows to dispense a non-preset volume of liquid.
