Abstract: The present invention involves a water gun having at least one pressurizable air/water storage tank, a pressurizing mechanism, a channel of release for shooting water and a release mechanism. The improvement lies in the particular release mechanism of the water gun. This release mechanism is for controlled flow with bursting release of water. It includes a plug valve which is located within a channel of release. The release mechanism has a first spring connected to the plug valve which biases the plug valve to its first, closed position. This first spring and the internal water pressure against the plug valve constitutes the "first force." Linkage connects a trigger to the plug valve such that activation of the trigger provides a second force which moves the linkage so as to move the plug valve from the first, closed position to the second, opened position and release of the trigger permits the first force to bias the plug valve back to its first, closed position.

Abstract: The present invention is a toy water bow which is operated by selectively releasing water from a water reservoir that is pressurized with air. The present invention is a toy device formed in the general shape of an archery bow that has a manually operated air pump incorporated into it. The air pump pressurizes a water reservoir and consequently exerts pressure on water contained therein. The pressurized air and water have an avenue of release that is regulated by a pull mechanism of the invention. When no force is applied to the pull mechanism, the pressurized air and water are held at bay with no means of release from the reservoir. When force is applied to the pull mechanism in a predetermined manner, water is released from the pressurized reservoir and is channeled through a narrow nozzle. The escape of the water through the narrow nozzle creates a stream of propelled water in the form of an "arrow" of predetermined length.

Abstract: A consumer product passage incorporating a mixing chamber for mixing air and liquid. Consumer packages of the present invention are capable of providing excellent spray qualities at typical consumer product flow rates (e.g., less than about 1.0 cubic centimeters per second) while simultaneously maintaining relatively low air to liquid ratios (e.g., less than about 0.06:1 on a mass basis) and relatively low pressures (e.g., less than about 50 psi). The package of the present invention also offers significant environmental and safety advantages. For example, it does not depend upon dissolved propellants; and it permits the use of water in place of volatile solvents as thinning agents since high surface tension fluids are actually sprayed better. Several packages of the present invention are illustrated, including a standard aerosol version, pump and spray versions, and a finger pump version.

Abstract: The present invention presents an improved pump piston for pressurizing liquid dispensing containers, and more particularly improved air inlet valve designs for such pistons. According to the present invention, the inlet valves are located remotely from the lower end of the pump piston, such that they are protected from contamination by liquid product and resulting degradation of performance. One inlet valve design utilizes a lost motion connection between the pump piston and upper cap, with structural elements of the upper cap and piston cooperating to form an inlet valve that is opened to admit air into the interior of the piston when the cap is pulled upward and tightly sealed when the cap is pushed downward. Another inlet valve design utilizes slits in the wall of the piston itself and the flexibility of the piston material to form an inlet valve that is opened to admit air into the interior of the piston when the cap is pulled upward and tightly sealed when the cap is pushed downward.

Abstract: A dual purpose pump for pressure vessels comprises a piston pump disposed within a pump cylinder.

Abstract: The present invention is directed to a toy water gun which is operated by selectively releasing water from a pressurized water reservoir. The present invention has a manually operated pump incorporated into the design. As the pump is cycled, water and/or air are drawn from at least one water storage reservoir. Once drawn, the water and/or air are forced into at least one pressure tank. As the amount of water and/or air forced into the pressure tank increases, the pressure of the air displaced by the water within the pressure tank increases. The pressure of the air on the water within the pressure tank increases with each cycle of the pump, until the pump can no longer overcome the pressure of the air on the water within the pressure tank. The pressurized air and water within the pressure tank has an avenue of release that is regulated by the trigger mechanism of the invention which has a safety pressure release within its design.

Abstract: A water gun having a water reservior adapted to be partially filed with water includes a piston pump having an outlet connected to the water reservior. A hand-operated slide member can be reciprocated by an operator for the water gun, and a rack connected to the slide member drives a gear train connected to a flywheel. The flywheel is connected through a crank wheel to the piston of the piston pump, and as the operator withdraws the slide member to rotate the flywheel, the piston is reciprocated back and forth within the piston chamber of the pump to drive air into the water reservior. The flywheel maintains the reciprocating motion of the piston as the operator slides the slide member forward in preparation for another stroke. In this way, the pumping action is maintained by the flywheel as the operator reciprocates the slide member forward to begin another stroke.

Abstract: A toy water gun has a pump/valve subassembly in which a flange plate is affixed to the outlet end of the cylinder member of an air pump. An integral tubular boss extends from the flange plate externally of the cylinder member outlet, the boss serving as the valve body of a discharge control valve. An annular gasket on the perimeter of the flange plate laterally outwardly of the cylinder member and the valve body forms a seal with the neck of a water reservoir, whereby the air pump outlet to the water reservoir and the inlet to the discharge valve communicate directly with the reservoir. A trigger operates the normally closed discharge control valve, and water under pressure is expelled from the reservoir through a discharge tube and nozzle when the trigger is pulled. A pressure-relief valve on the air pump prevents the pump from pressurizing the air pumped into the reservoir to a pressure above a predetermined value.

Abstract: A manually operated continuous aerosol sprayer which eliminates the need for the use of potentially environmentally dangerous substances. A container is provided to hold a liquid and an inflatable bladder is located inside the liquid container. A pump is provided for filling the bladder with air from the outside atmosphere. The open end of the inflatable bladder is attached to the pump so that it may be readily filled by the pump with the remainder of the inflatable bladder extending into the liquid container. When the bladder is inflated it expands causing the liquid in the container to become pressurized. The pressure from the inflation of the bladder causes the air and the liquid to be forced into a spray chamber where they mix and are forced out a spray nozle as an aerosol spray.
