Abstract (en)
[origin: FR2689866A1] An extemporaneous mixture of two separate components (S, A) is produced by placing the first component (S) in a can (1) containing a relatively highly pressurized backfeeding capsule (5). A valve (12) is controlled according to the value of the ambient pressure relative to a reference pressure. The second component (A) is placed in the capsule (5) before its insertion into the can, and the can (1) is sufficiently pressurized with a propellant gas (4) for the valve (12) to remain closed during storage and when the capsule (5) has been activated. Said components (S, A) may be mixed by actuating the dispensing head (1) to cause a pressure drop in the can (1), which is positioned so that only propellant gas comes out of the dispensing head, whereafter the valve (12) opens, and the component (A) in the capsule comes out and mixes with the component (S) in the aerosol can.
