Aerosol intended for dispensing several components for the production of a multi-component material, in particular a paste-like cosmetic material, at least comprising a dispensing assembly, a main container (1) and one or more separate auxiliary containers for components to be dispensed, in which the one or more auxiliary containers are accommodated in the main container and designed in such a way that they can be removed from the main container together with the dispensing assembly, in which the dispensing assembly comprises piston pumps for pumping the components to be dispensed out of the containers to one or more dispensing openings, a common control part being present for operating the piston pumps, in which the piston pumps comprise a piston chamber (7, 25;
- 92, 66;) with an inlet and an outlet and a piston which is movable in the piston chamber (5, 23), while a non-return valve is present in the inlet and the outlet of the piston chambers of the piston pumps, in which the non-return valve in the inlet of at least one of the piston chambers of the piston pumps which are connected to the auxiliary containers is in the form of a non-return ball check valve, and in which at least one of the auxiliary containers is in the form of a container with variable volume.
Aerosol intended for dispensing several components in foam form for the production of a multi-component foam material, in particular a paste-like cosmetic foam, at least comprising a dispensing assembly, a main container and one or more auxiliary containers for components to be dispensed, which dispensing assembly comprises dispensing means for conveying the components to be dispensed out of the containers to one or more dispensing openings, and a control part is present for operating the dispensing means, while air pumping means, mixing means and foam-forming means are also present for mixing the components with air prior to dispensing and foaming thereof for the formation of a foam.
