Abstract: Toy water guns having removable pre-pressurizable water cartridges and the pre-pressurizable cartridges themselves and water charging systems for them. More particularly, the present invention is directed to a toy water gun having a pre-pressurizable water cartridge which can be charged using a pump located on the water gun or an auxiliary adapter connected to an external pressurized water source for quickly charging the pre-pressurizable water cartridge either installed in the water gun or separately, the pre-pressurizable water cartridges, recharge adapters and methods of filling the pre-pressurizable cartridges when installed in a water gun and when removed from a water gun.

Abstract: The present invention relates to a device for discharging a fluid under pressure comprising: an intake port for receiving fluid from a source of receiving fluid; a pressurizable tank for fluid storage; a discharge port; a pump assembly having a first passageway in fluid communication with the intake port and the tank and a second passageway in fluid communication with the tank and the discharge port, the pump assembly being operable to pressurize the fluid in the tank; and an actuator associated with the discharge port to allow pressurized fluid to be discharged selectively through the discharge port. Preferably, the discharge device is in the form of a toy water gun having one or two discharge ports.
