The air flow is transmitted into the interior of the bottle to pressurize the liquid and urge the latter into a liquid outlet conduit which has a lower end extending into the liquid in the bottle and a discharge end outside the bottle. The arrangement is further provided with an element for spraying the liquid when the latter under the pressure supplied into the bottle enters the discharge end of the outlet conduit.

Abstract: A toy water gun assembly capable of ejecting water in bursts or in a continuous manner, is disclosed. A separate, pressurizable water container is connected by a flexible hose, to a pistal shaped member. A section of the flexible hose, mounted in the pistol shaped member, is continuously clamped by a lever. A spring biases the lever to prevent the release of a water stream through a nozzle which is mounted on the front of the pistol shaped member. A trigger member having a pointed pawl pivotably mounted thereto, is operatively connected to the lever. An initial movement of the pawl member caused by a quick pull on the trigger member momentarily removes the lever from its position clamping the hose. Additional movement of the pawl causes it to slide off the lever, thereby allowing the lever to return to its regular position wherein the hose is clamped.

Abstract: A dispensing type container wherein a fluid product is dispensed under pressure from the container in the absence of special charging gases such as Freon and the like which are customarily utilized and which have been found to be objectionable. The container is charged with air under pressure from the atmosphere and includes a built-in cylinder which is associated with a separately formed and mounted piston. When the container is to be charged for dispensing the product, it is merely placed on the piston and reciprocated several times to pump air thereinto under pressure. The piston is reusable.

Abstract: A syringe of the slide piston pump type is adapted to overcome a pressure resistance at its outlet as may be provided, for instance, by a filter in communication with the outlet and through which the syringe is to pump a medium, particularly a liquid medium, for filtration. The syringe comprises a cylinder containing a piston, and a piston rod. The piston rod is fixed to a second piston sliding within a longitudinal bore in the first-mentioned piston. The bore and the second piston cooperate to define an air-filled pressure chamber connected to a cylinder chamber, defined by the first piston and the cylinder, by a valve. Inward movement of the piston rod produces an over-pressure (e.g. 16 atmospheres) in the pressure chamber to open the valve to apply the over-pressure to the liquid or other medium in the cylinder chamber to overcome the pressure resistance of the filter and enable the liquid to be forced through the filter.
