A method and device for controlling the flow of liquid from drinking containers, wherein a membrane is movably connected to a valve to form a valve, controlled by negative pressure, for liquid from a drinking container, the force resulting from the pressure difference (P1−P2) across the membrane, opening the valve, even by positive pressure (P3) within the drinking container, caused by a carbonated refreshing drink, for example.
