Abstract
An apparatus for dispensing at least two liquid compositions, one as a wet spray and one as an aerosol spray comprising at least two liquid supply reservoirs, an air supply for pressurizing the reservoirs, and individual capilliary tubes connecting the reservoirs and a pressurized air source to a dispensing wand. The wand comprises a solid handle with ducts therein connected at one end to one of the capilliary tubes, each duct provided with a suitable valve for controlling fluid flow therethrough. A tube is attached at the opposite end of the handle with capilliary tubes therein attached to the liquid ducts passing therethrough to a nozzle head attached to the opposite end of the tube. The nozzle head is provided with a nozzle to dispense a liquid in the form of a wet spray and a nozzle to dispense a liquid as an aerosol spray with pressurized air passing therethrough and mixing with the liquid to provide the aerosol spray. The pressurized air passes through the handle directly into the tube for mixing with the liquid in the nozzle to form the aerosol spray to apply insecticides both in liquid spray form and as an aerosol spray.
