Abstract
An improved spraying device for mixing a first fluid with a second fluid prior to dispensing into the environment. The spraying device includes a spraying head connected to a cartridge bottle. A shroud covers the spraying head to cartridge bottle connection. The chemical remains in a closed system even after the cartridge bottle is attached to the spraying head. A unique gear and/or cam system is provided to open the flow path of the second fluid and provide a positive operation. Also, the orifice diameter of the second fluid flow path is predetermined.
