Abstract: A dispenser for soap lather has a vessel for a larger supply of liquid soap and a tank for a smaller supply of liquid soap and for a body of air above the smaller supply. One or more bellows are used to pump compressed air into a portion of the tank when a user desires to obtain a batch of lather. The compressed air expels a certain quantity of liquid soap from the tank into a lather generator and the lather generator further receives some compressed air to form a batch of lather which is dispensed into or onto the hands of a user. When the bellows expands or expand it or they can draw air into or along the outlet of the lather generator to retract any remnants of lather. Alternatively, a discrete pump can be provided to blow out any remnants from the lather generator in response to or during expansion of the bellows. The discharged quantity of liquid soap is replenished in the tank by way of an adjustable conduit connecting the vessel with the tank.

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.

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.

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.

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.

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

Once the container is pressurized the contents may be applied by a spray valve. The repressurizing cap can be removed from the container by a simple locking mechanism; a locking slide bar that moves in and out of a locking groove located on the container.
