Abstract
A pressure container with an outer container (20) and a constantly deformable or compressible inner container is arranged within the outer container (20), whose container wall is constructed of a metallic foil. A fill material chamber (11) for fill material (12) is arranged in the inner container (10) and in the outer container (20), a propellant chamber (21) is formed for propellant (22, 23), which are separated from one another in a fluid- and/or gas-tight manner. The pressure container is furthermore provided with a cover part (25) for sealing the containers (10, 20), on which a valve part (30) is arranged for dispensing fill material (12) from the fill material chamber (11) to the outside. For improving the pressure container it is proposed that a compensation body (41) be provided in the inner container (10) for the purpose of compensating volume variations in the fill material chamber (11).
