Abstract: A sprayer for forming and spraying a dispersion of a dispersible substance from a cartridge and a liquid dispersion medium from a source. The sprayer has a first passageway comprising a pump, wherein the first passageway is configured for supplying at least the liquid dispersion medium from the source in response to operation of the pump; a receptacle for removably receiving the cartridge; and a second passageway in fluid communication with both the receptacle and the first passageway for supplying the dispersible substance from the cartridge to the first passageway and, thereby, forming the dispersion in response to operation of the pump. A discharge apparatus is in fluid communication with the first passageway for dispensing the dispersion from the sprayer.
