ABSTRACT:
A valve for venting a container has a valve housing with an annular chamber. A ring member with a first axial and a second axial end is arranged in the annular chamber. The ring member has a first sealing lip at the first axial end and a second sealing lip at the second axial end. A first channel and a second channel extend axially along the ring member for venting the container. The first channel vents in a first direction and the second channel vents in a second direction opposite the first direction. The first sealing lip closes off the first channel such that the first sealing lip and the first channel function as a relief valve. The second sealing lip closes off the second channel such that the second sealing lip and the second channel function as a relief valve.
