<p>A sealing valve arrangement (12) for a container containing a fluid, wherein a supporting element (14) comprising a control channel (15) in the border region of the supporting element (14) and a securing element (16) comprising a passage channel (18) are disposed on top of one another over the fluid storage (13') of the container. A sealing valve (1) having smaller radial dimensions than these elements (14, 16) and a valve channel (2) for connecting the control channel (15) and the passage channel (18) are provided between the supporting element (14) and the securing element (17), wherein the sealing valve (1) comprises a first sealing surface or edge (5) for sealing the passage channel (18) from the control channel (15) and a second sealing surface or edge (8) for sealing the valve channel (2) from the control channel (15). The sealing valve (1) operates in case of pressure above atmospheric and sub-atmospheric pressure within the fluid storage (13').</p> |
