Abstract (en)

[origin: WO2021204562A1] To provide a valve device by means of which both a positive pressure and a negative pressure in an interior of a container can be equalised and which is as simple as possible to produce, the invention proposes that the valve device comprises an adapter element, a first valve element, a second valve element, a first membrane and/or a second membrane, wherein the first valve element blocks a fluid inlet opening of the adapter element in a closed state, and in an open state releases the fluid inlet opening so that fluid can flow from surroundings of the valve device into an interior of the container, and wherein the second valve element blocks a fluid outlet opening of the adapter element in a closed state, and in an open state releases the fluid outlet opening so that fluid can flow out of the interior of the container into the surroundings of the valve device.
