A method and device for controlling the flow of liquid from drinking containers, wherein a membrane (12) is movably connected to a valve (50) 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 (12), opening the valve (50), even by positive pressure (P3) within the drinking container, caused by a carbonated refreshing drink, for example.

L'invention concerne un dispositif, et un procédé correspondant, pour réguler le flux de liquide s'écoulant de contenants à boissons. Une membrane (12) est reliée mobile à une soupape (50), ce qui permet de réguler le flux de liquide s'écoulant de contenants à boissons, sous l'effet d'une pression négative: la force appliquée résulte de la différence de pression (P1 - P2) au niveau de la membrane (12), et la soupape (50) s'ouvre, même sous l'action d'une pression positive (P3) qui résulte, dans le contenant, de la présence d'une boisson gazeuse rafraîchissante, par exemple.
