Valve device for opening a container comprising a re-aeration mechanism

摘要

Valve device for arrangement in the area of a container opening and for metered discharge of a medium from the container, comprising a first valve that seals the container opening as long as a pressure difference between the interior of the container and the exterior of the container is smaller than a first predetermined limit value and that opens the container opening for the medium when the pressure difference between the interior of the container and the exterior of the container is greater than the first predetermined limit value, and a second valve that opens the container opening for admission of air as long as a pressure difference between the interior of the container and the exterior of the container is smaller than a second predetermined limit value and that seals the container opening for admission of air when the pressure difference between the interior of the container and the exterior of the container is greater than the second predetermined limit value. In the valve device, one of the first valve and the second valve is integrated in the other of the first valve and the second valve. The present invention also includes a container comprising the valve device.
