Abstract: An adjustable amount of liquid is reproducibly withdrawn from a container having a pre-chamber in free flow communication with the interior of the container. The pre-chamber is initially filled with an amount of liquid from the container and is in communication with a measuring chamber. The measuring chamber has an adjustably pre-set volume and is in communication with a closeable outlet. Thus, after the amount to be withdrawn from the measuring chamber has been adjusted, discharge of the preset volume is effected through the outlet without the necessity of additional manipulations such as shaking the container or separating the dosage metering part from the container to effect the discharge of a precise amount of liquid.

Abstract: Dispensers for liquids are provided having structure for containing a pool of liquid in the dispenser, to a predetermined level. A discharge chamber contains air above the level of liquid and a discharge device extends upwardly at least partly through the discharge chamber from below the level of the pool and has an external outlet. The discharge device includes a foamer chamber having a wall defining very small holes located above the pool level, and pressure means is coupled to the discharge chamber and operable to increase the pressure in the discharge chamber so that a pressure applied on the pool level drives liquid into the discharge device. Simultaneously air is forced through the small holes in the foamer chamber to meet the liquid passing through the foamer chamber where progressive foaming takes place before the resulting foam is forced through a discharge outlet.

Abstract: The invention provides a dispenser for dispensing one or two liquids simultaneously. For two liquids the dispenser has a pair of inverted containers defining bottom openings with the containers arranged in side-by-side relationship. A base is sealingly attached to the containers and has two reservoirs and associated dispensing openings. The arrangement is such that liquid from the containers will pool in the reservoirs below the dispensing outlets creating a condition of equilibrium in the containers. When the user disturbs the equilibrium, liquids from both containers flow out through the respective dispensing outlets for mixing in use, and then after dispensing air, flows into the dispenser to replace dispensed liquid thereby allowing equilibrium to again be established.When the invention is used for dispensing a single liquid, one container contains liquid and the second container is squeezed to disturb the equilibrium and cause dispensing.

A second check valve fixedly mounted to the lower portion serves to open and close a liquid passageway from the dosing reservoir to an outlet orifice, acting oppositely to the first check valve.

Abstract: The present invention is a metered liquid dispenser. A liquid dispenser has a liquid volume metering element located on a base attached to the top of the neck of a liquid dispenser. Using a lift fill mechanism, the metering element is vertically slid relative to the base to dispense a measured liquid volume. One-way valves located in the base and the top of the metering element alternately act to displace air from the element, and then provide suction to draw a measured liquid volume from the liquid dispenser through a dip tube into the element. The liquid is dispensed by inverting the metered liquid dispenser. The metering element has liquid level markings to indicate the liquid volume being entered to the element for dispensing, and is preferable partly transparent to visually display the liquid in the metering element.

If preferred, upon actuation liquid will flow initially, and then the bell can be made to seal the outlet structure to stop liquid flow thereby simulating a pumping action.

Abstract: A non-aerosol fluid dispenser includes a pump defining a fluid chamber associated with the fluid path extending between the container and fluid outlet. The pump comprises a base presenting a chamber opening, a generally non-deformable panel, a hinge about which the panel swings relative to the base, and a hollow, collapsible bellow section extending between the panel and the base. The dispenser includes a boss sealingly received within the chamber opening, with the fluid path extending through the boss and into the chamber between the supply and discharge valves. Accordingly, when the panel is swung toward the base, the bellows section uniformly collapses, whereby positive pressure created within the chamber closes the supply valve and opens the discharge valve for discharging fluid through the dispenser outlet.

Abstract: A dispenser for liquid is provided having a relatively stiff or rigid container above a resiliently deformable reservoir structure. The container is coupled to the reservoir structure and the container has a bottom outlet inside the reservoir structure which also includes a discharge structure leading from the inside to the outside of the reservoir structure. Liquid is dispensed when the user causes relative movement between the container and the reservoir structure to increase the pressure in the reservoir structure and to thereby force liquid from the reservoir structure through the outlet passageway.

Abstract: A liquid measuring device comprises a cap which is adapted to fit on a liquid container. A reservoir adapted to hold a dose of liquid is mounted on the cap. The reservoir has a opening in the top which is covered by a removable reservoir cap. A tube runs from the inside of the liquid container through the cap and upward into the reservoir. The liquid is forced from the container, through the tube and into the reservoir by squeezing the sides of the container inwardly. Similarly, liquid can be forced back into the container by turning the device upside down and squeezing inward on the sides of the reservoir. The liquid measuring device is adapted to fit any size pharmaceutical bottle or other liquid containers and may be reused.

Abstract: The invention provides dispensers for liquids having a dispensing opening in the side of the dispenser and liquid is stored in a main body of a resiliently deformable container coupled to a neck structure which has a bottom outlet inside a base structure. In use, the dispenser is first lifted and then tilted through about 30 to 50 degrees before squeezing the container. The tilting action causes some of the air in the base structure to be trapped thereby minimizing the effect of temperature compensation on response rate. Consequently, the squeezing action is immediately available to force liquid to pass through the base structure and issue from the side dispensing opening. Various structures can be made consistent with the invention to accommodate a range of liquids having different properties.

The one-way monitoring valve, downstream from the collecting chamber, may be formed as a duckbill valve of elastomeric rubber having an exit slit at the dispensing end. This slit, normally closed, will open upon pressure from a product flow. Excellent control of dispensing amounts is achieved through the pumping mechanism.

Abstract: A water gun which utilizes a piston movable within a piston cylinder by a manually operated handle. Movement of the piston to a retracted position within the piston cylinder will result in supplying water from a water reservoir into the piston cylinder. Moving of the piston in an inward position within the piston cylinder will result in expelling water from the piston cylinder into an elastic bladder. The quantity of water being expelled from the piston cylinder within the elastic bladder will cause the elastic bladder to expand substantially, and at the point of full inward motion of the piston, the handle will come into contact with a discharge valve which will be moved to cause release of the water that is confined within the elastic bladder. This water is to be expelled through a nozzle to be emitted into the ambient in a form of a stream.
