In which the valve is first placed in the container which is then sterilised; it is next filled with the products to be sprayed, together with the propulsion gas, by introducing them through the valve. The empty aerosol container may be filled with a sterilising agent in the form of a gas or vapour through the valve, after placing the latter in position. The sterilising agent is eliminated, after a sufficient time for the complete destruction of any germs, and the container is filled, through the valve, with the products to be sprayed or distributed in the form of foam, together with the propulsion gas. The sterilising agent may be eliminated by successive aspirations and rinsings by means of an inert gas. The apparatus includes a closing position where the valve is fixed to the recipient, a filling device for introducing the sterilising agent, a suction device for eliminating the latter and a device for introducing the product to be sprayed together with the propulsion gas. |
