Aerosol container stored with two containers of propellant gas - has gas mixed by puncturing two internal containers when aerosol is ready for use

摘要

The container is double walled and is furnished with two internal spaces (A) and (B) located at the base of the inner container. Each of the spaces contain part of the propellant gas. The gases are mixed after the containers have been released by puncturing the surfaces (23a) and (23b) with the prongs (3a) and (3b). The propellant gas then occupies the outer cylinder and may connect to the inner cylinder through the valves (4) and the inlet holes (24) into the inner cylinder which contains the product. The product is discharged through the pipe (22) on activation of the valve (13-15).
