ABSTRACT:
The invention is concerned with a method and apparatus for dispersing an active ingredient, such as a fumigant. The active ingredient is placed in a container and a pressurized solvent/propellent is subsequently introduced. The solvent/propellent expands to adopt a liquid phase and a gaseous phase. The liquid phase serves to absorb the active ingredient and the gaseous phase serves to propel the borne active ingredient out of the apparatus where further expansion takes place and the active ingredient is dispersed in a fog or mist.
