PCT No. PCT/FR93/00347 Sec. 371 Date Dec. 1, 1993 Sec. 102(e) Date Dec. 1, 1993 PCT Filed Apr. 6, 1993 PCT Pub. No. WO93/21085 PCT Pub. Date Oct. 28, 1993.In order to form an extemporaneous mixture of two components (S, A) isolated from each other, the first component (S) is placed in a can (1) in which a resupply capsule (5) under relatively high pressure is disposed, a valve (12) being provided and controlled depending on the value of the ambient pressure relative to a reference pressure. The second component (A) is introduced into the capsule (5), before installing this capsule in the can; the can (1), is put under a pressure by propellent gas (4) sufficient for the valve (12), during storage, and even though the capsule (5) has been brought into service, to remain in the closed state; in order to form the mixture of the components (S and A), by actuating the dispensing head (1), a reduction is brought about in the pressure in the can (1) placed in a position such that only propellent gas escapes from the dispensing head, which causes the valve (12) to open, the component (A) contained in this capsule to escape and to be mixed with the component (S) from the aerosol can.
