The extinguisher consists of a reservoir (2) of the product (3) to be sprayed, an ejector (4) for the product and a percussion head (5) attached to a tube (6) inside the reservoir. The tube contains a pressurised gas capsule (10) adjacent to the head, and an additive (15) to be mixed with the product once the capsule has been set off. The second part (11) of the tube has at least two chambers for additives (15,16) separated by seals (17-19) which can slide along the tube under the effect of the pressurised gas and release the additives into the reservoir. The chambers are situated one above the other, and the seals are in the shape of cylindrical plates.
