Claim:
1. A device for receiving or dispensing a fluid comprising a container and a closure piece, the closure piece comprising: a) a connecting region for connection of the container, wherein a removal opening is arranged in the connecting region in such a manner that said removal opening communicates with an interior space in the container, and b) a dispensing region in which, in order to dispense the fluid, a dispensing opening is formed, and c) a dispensing channel which connects the dispensing opening fluidically to the removal opening, wherein a dispensing section of the dispensing channel communicates with the dispensing opening and a removal section of the dispensing channel communicates with the removal opening, d) wherein the dispensing channel comprises a valve device which, in a closed position, closes the dispensing channel in a fluid-tight manner and, in an open position, permits passage of the fluid through the dispensing channel if there is a positive pressure of sufficient size in a fluid in the removal section, and wherein the valve device has two valve openings which are arranged next to each other on a valve surface and of which a first valve opening communicates with the dispensing opening via the dispensing section of the dispensing channel and a second valve opening communicates with the removal opening via the removal section of the dispensing channel, and there is a continuous, flexible membrane which, in the closed position of the valve device, bears against the valve surface so as to be raisable in regions and thus closes off the valve openings from each other in a fluid-tight manner, a container wall of the container is designed so as to be flexible at least in regions and, in the connecting region, the closure piece has at least one connecting surface to which a connecting section of the container wall is fastened, and the connecting section of the container wall is designed so as to be flexible, and the valve surface with valve openings is arranged on the at least one connecting surface of the closure piece in such a manner that a region of the connecting section of the container wall forms the flexible membrane of the valve device.
