Abstract:
A sealing valve arrangement (12) for a container containing a fluid, the sealing valve arrangement comprising:a supporting element (14) comprising a control channel (15) in the border region of the supporting element (14); a securing element (16) comprising a passage channel (18), the supporting element and securing element being disposed on top of one another over a fluid storage (13â€²) of the container, and a flexible sealing valve (1) between the supporting element (14) and the securing element (16), the sealing valve having a smaller radial dimension than the supporting element (14) and the securing element (16) and comprising a valve channel (2) for connecting the control channel (15) and the passage channel (18), a first sealing surface or edge (5) for sealing the passage channel (18) from the control channel (15), a second sealing surface or edge (8) for sealing the valve channel (2) from the control channel (15), and recesses at a periphery of the sealing valve below the first sealing edge (5); said recesses defining an area of weakness in said sealing valve to allow said sealing valve to flex, whereby when a pressure above said valve is greater than a pressure below said valve, said valve will flex to form a gap adjacent said first sealing surface, and when a pressure below said valve is greater than a pressure above said valve said valve will flex to form a gap adjacent said second sealing surface.
