ABSTRACT:
An apparatus for dispersing an active ingredient, such as a fumigant, fertilizer or room freshener in which the active ingredient is placed in a sample cylinder and a pressurized solvent/propellent is subsequently introduced from a source. 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 through a dispensing outlet where further expansion takes place and the active ingredient is dispersed in a fog or mist. Flow restrictors create a pressure differential between the sample cylinder outlet and a by-pass portion to enable total absorption of the active ingredient. The flow restrictors and conduits for the system are contained in a mixing head for the sample cylinder. The system is particularly suitable for the spraying of insecticides where a metered amount of active ingredient is to be dispersed or for exhausting a total supply of active ingredient.
