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.
In a squirt gun of the type comprising a housing having a hollow interior portion, a filling passageway between the housing's hollow interior portion and the housing's exterior, and a squirting passageway between the housing's hollow interior portion and a nozzle at the housing's exterior, and having an actuatable trigger adapted in and biased towards a first position in which communication through the squirting passageway from the housing's hollow interior portion to the nozzle is denied, and movable to a second position in which communication between the housing's hollow interior portion to the nozzle is enabled, the improvement whereby the hollow interior portion comprises a sealed and rigid pressure vessel with one or more openings communicating with the passageways, said vessel comprising therein a compressible gas-filled and sealed bladder, and whereby the gun is adapted to receive water at a positive pressure through the filling passageway and into said vessel and said pressure causes said bladder to compress and become pressurized, and whereby, when the trigger is in the first position, the water received into said vessel is retained therein under said bladder's pressure and, when the trigger is actuated into to the second position, said retained water is expelled from said vessel by said bladder's pressure and through the squirting passageway and the nozzle to the housing's exterior.
In a squirt gun of the type comprising a housing having a hollow interior portion, a filling passageway between the housing's hollow interior portion and the housing's exterior, and a squirting passageway between the housing's hollow interior portion and a nozzle at the housing's exterior, and having an actuatable trigger adapted in and biased towards a first position in which communication through the squirting passageway from the housing's hollow interior portion to the nozzle is denied, and movable to a second position in which communication between the housing's hollow interior portion to the nozzle is enabled, the improvement whereby said hollow interior portion comprises a sealed and rigid pressure vessel with one or more openings communicating with said passageways, said vessel comprising an interior tubular surface and having disposed therein an energy-storing piston slidably sealing said interior tubular surface to define water-holding and energy-holding portions of said vessel, said vessel further having disposed therein an energy-storing element having a high energy state and a low energy state and biased towards its low energy state, said element in communication with said piston and biasing said piston towards said water-holding portion, and wherein the gun is adapted to receive water at a positive pressure through the filling passageway and into said vessel and said pressure causes said element towards its high-energy state and said piston towards said energy-holding portion, and whereby, when the trigger is in said first position, the water received into said vessel is retained therein, and when the trigger is actuated into its second position, the retained water is expelled from said vessel to the housing's exterior through the squirting passageway and the nozzle by said energy-storing element's bias of the piston towards the water-holding portion.
