Abstract (en)
[origin: WO03080462A1] The invention relates to a valve device for arranging in the region of the opening of a container and for the dosed outflow of a medium from the container. Said device comprises a first valve (5) which seals the opening of the container for the medium as long as the pressure difference between the inside of the container and the outside of the container is lower than a first pre-determined threshold value, and which opens the opening of the container for the medium when the pressure difference between the inside of the container and the outside of the container is higher than the first pre-determined threshold value. The inventive device also comprises a second valve (6) which opens the opening of the container for re-aeration as long as the pressure difference between the inside of the container and the outside of the container is lower than a second pre-determined threshold value, and which seals the opening of the container for re-aeration when the pressure difference between the inside of the container and the outside of the container is higher than the second pre-determined threshold value. The invention is characterised in that one of the valves is integrated into the other valve.
