Gravity fed sprayer

Abstract

A sprayer apparatus for dispensing liquid fertilizer, weed control or liquid insecticide from an elongated storage tube using one hand. A see-through plastic storage tube has a spray nozzle one end and a handgrip with trigger on the opposite end. Compressing the trigger moves a trigger rod to move a piston that forces gravity fed liquid through the spray nozzle. The spray nozzle can be located in a housing having a convex curved outer surface along with a wheel protruding from the bottom surface of the housing. The wheel can have conical side edges and a flat exterior side. Alternatively, the wheel can have rounded outer edges. Visible markings on the exterior of the plastic storage tube can tell the user the remaining amount of the liquid stored inside. An optional protruding handgrip can be located halfway down the storage tube for allowing the device to be controlled by two hands. A second version includes a two way valve located inside the storage tube. The valve connects the spray nozzle to either the interior of the storage tube or to an interior siphon tube that has an opening located inside the handgrip. The two way valve allows the device to gravity feed liquid to the spray nozzle when the spray nozzle is located adjacent to the ground. The second position of the valve allows the device to suction liquid from inside the handgrip when the spray nozzle is oriented above the the handgrip.
