ABSTRACT:
A toy water gun includes a molded plastic handle having a hose coupling thread at one end and a bottle thread coupling at the other end. A trigger and a nozzle are formed in the handle with the trigger displacing a ball from its seat to form a water jet. A check valve includes a ball that is held against its seat in the hose thread coupling end of the handle by pressure in a water reservoir. A siphon tube is used in one version for reaching to the bottom of a plastic bottle reservoir that is screwed into the bottle thread coupling of the handle. An adapter may be screwed into the bottle thread coupling of the handle and coupled to one or more plastic bottle reservoirs that are carried in a backpack. The water gun is charged with pressurized water from a household water spigot by screwing it to the spigot and forcing water under pressure into the reservoir. A two piece handle version is also disclosed.
