Abstract: A container for fluids, in particular fluids containing gas, comprises an outer casing of flexible, pressure resistant material, at least a gas and/or fluid tight inner casing of flexible material lying inside the outer casing and being separated therefrom, and at least a filling connection for filling the inner casing. As a result, the container is collapsible so that filling the container may take place from the collapsed condition and filling is therefore possible without pressure difference while the fluid does not enter an empty space. The egress of gas from the fluid is substantially reduced thereby. When fluid is discharged from the containe, the volume of the container can also decrease by collapsing so that also during use of the fluid gas is prevented from egressing. Consequently, the quality of the fluid is maintained, both during filling of the inner casing with fluid and during discharge of fluid from the inner casing.

Abstract: A closing valve for a container comprises a closing jacket connected therewith, which closing jacket is provided on the inside with a narrowed and a widened portion, and a valve part movable in this closing jacket. This valve part has a closing element and a clamping element which is provided on at least the outside with a thickening which, when the passage through the closing jacket is sealed by the valve part, cooperates with the widened portion in the closing jacket. Furthermore, a head part movable in the closing jacket back and forth is provided, by means of which the valve part can be moved with respect to the closing jacket such that the passage therethrough can be released and/or closed, while when releasing the passage through the closing jacket, the thickening on the outside of the clamping element is brought into the narrowed portion of the closing jacket, as a result of which the clamping element reaches a position in which it is engaged by the head part.
