ABSTRACT:
A squirt gun includes a hollow housing in the form of a gun with a liquid dispensing assembly within the housing. The liquid dispensing assembly includes a rigid pressure vessel having either a gas-filled compressible bladder or a spring-loaded piston disposed within. The vessel is connected to a flexible tube with a nozzle at one end, and the gun is adapted to receive and expel water to and from the vessel through the nozzle. A pivotable trigger cooperates with the flexible tube to either enable both the receiving and expelling, or to deny the expelling of the water. To fill the gun, water is forced into the vessel under pressure, which compresses the air bladder or the piston to retain that pressure within the water-filled vessel. To expel the retained water, the trigger is moved to an “open” position, which allows the water to be forced from the pressurized water-filled vessel, through the nozzle, and from the gun as the air bladder or the piston expands. An adapter is provided which is threadable on a faucet, for filling the squirt gun with water at the pressure of the water supply.
