A two-chamber container for two gas-pressurized components kept separately, for example liquids which are miscible. An outer chamber contains a first component and is provided with a dispensing valve whose interposed connecting member leads from the interior of the outer chamber to the outside and is adapted to be closed by a plug. The second component is contained in an inner chamber mounted in the interior of the outer chamber. The inner chamber is an entirely separate, self-contained vessel supported in the interior of the outer chamber. The interior end of the interposed connecting member terminates in a cup-shaped receptor member which is disposed above and around the distal end portion of the inner chamber such that a radial and axial clearance of 1-2 mm between the receptor member and the distal end is provided. The inner chamber has a desired rupture site which can be broken by force from outside, for example by pivoting or pushing-in the dispensing valve. In this manner ready communication is established between the interiors of the two containers so that spontaneously complete mixing of the two components is achieved.
