Abstract (en)

[origin: WO9421384A1] Foam-forming unit, in particular intended for an aerosol, at least comprising a mixing chamber (13; 47), with a propellant inlet (14; 48) and an inlet (15; 29) for a liquid to be dispensed in foam form, which mixing chamber (13; 47) by means of a control valve provided with return means, can be placed in communication with an outlet channel (10; 44) opening out into an outflow aperture (9; 43), one or more foam-forming parts (8; 52) being present in the path between the inlets and the outflow aperture (9; 43), while the unit also comprises a non-return valve (18, 22; 38, 39) through which an aerosol can be placed under pressure using pressure means, during which operation the outflow aperture (9; 43) is in communication with the pressure means, while valve means are present which interrupt the communication between the foam-forming parts (8; 52) and the environment at least in one direction, which valve means can be opened when the aerosol is to be used for the dispensing of foam and aerosol comprising such a foam forming unit.
