ABSTRACT:
An inner container having a dispensing valve is situated within a flexible sack which in turn is situated within an outer container having a cover and a dispensing valve. The sack contains one package component and the inner container contains the other package component and a propellant. A further propellant is situated outside of the sack within the outer container. The inner dispensing valve is constructed as a dosage valve and issues into the interior of the outer dispensing valve. The latter is kinematically coupled with the inner dispensing valve and possesses a blocking system which blocks its interior relative to the interior of the sack when the outer dispensing valve is open. The particular construction and the flow-related coupling of both dispensing valves permits a defined dosed dispensing of both package components with a defined mixture ratio.
