Fluid dispensing device
A fluid dispensing device of the type, including a shut off valve means for controlling fluid flow through the device and an actuating trigger operable to cause the shut off valve to adopt an open position in which fluid can be dispensed from the device and a closed position, a control meter which enables the volume of fluid being disposed to be measured, a latching mechanism operable to hold the shut off valve in the open position and cause the shut off valve to adopt the closed position when the predetermined volume of fluid has been dispensed, and a setting mechanism being operatively connected to the control meter for indicating a predetermined volume of fluid required to be dispensed and indicating when that predetermined volume has been dispensed.

Dispense pump with heated pump housing and heated material reservoir
A heated dispense pump overcomes the limitations of conventional systems providing for reliable and efficient heating of the dispensed material in a system that is compact, lightweight, and accurate. A pump housing and cartridge body are formed of a thermally conductive material such as copper, aluminum, or an alloy combination thereof. A heater element is applied directly to the body of the pump housing, and a thermocouple is included to provide for closed-loop controllability. The material flows though the cartridge body and is heated prior to release at the dispense tip. The heated elements, including the pump housing and cartridge body, are thermally insulated from the pump motor and pump gantry to prevent the escape of heat from the system and to protect those adjacent components from heat damage. An optional syringe heater is provided for heating the material in the syringe, and for controlling the temperature of the material, in closed-loop fashion. In this manner, the temperature of the material in the syringe and the temperature of the material in the pump can be controlled independently of each other.

Metered dose squeeze dispenser having a dip tube with a rotatable leg
A liquid metered dispensing squeeze bottle includes: (a.) a squeezable container having an opening for dispensing liquid therefrom at one end and a bottom at the other end; (b.) a nonflexible trap chamber of a predetermined volume, connected to the opening of the container; (c.) a dip tube, and (d.) a one way valve at the bottom of the dip tube. There is an inlet leg that freely rotates around the bottom of the dip tube and a drive mechanism, such as a counterweight or a float, to assure that the leg extends into an air pocket when the container is tilted for liquid squeeze dispensing.

Ophthalmic dispenser and associated method
An ophthalmic dispenser has a rigid housing defining a fluid-receiving chamber, a flexible bladder receivable within the fluid-receiving chamber, a pump coupled in fluid communication with the fluid-receiving chamber, and a nozzle having a valve defining an annular, axially-extending valve seat, an outlet aperture coupled in fluid communication between the valve seat and the pump, and a flexible valve cover extending about the valve seat and forming an annular, axially-extending interface therebetween. The valve interface is connectable in fluid communication with the outlet aperture, and at least part of the valve cover is movable between (i) a normally closed position with the valve cover engaging the valve seat to close the interface and form a fluid-tight seal therebetween, and (ii) an open position with at least part of the valve cover spaced away from the valve seat in response to pumped fluid flowing through the outlet aperture at a pressure greater than a valve opening pressure to allow the passage of pressurized fluid therebetween. A spring is drivingly connected to the housing and moves at least one of the pump and housing relative to the other to actuate the pump. The rigid housing is mountable within a cartridge which, in turn, is mountable within a dispenser housing including an eyelid depressor and a trigger for simultaneously actuating the eyelid depressor and pump.

Beverage dispenser
Apparatus for dispensing a post-mix beverage is characterized by a beverage concentrate metering system comprising a reservoir of beverage concentrate, a disposable pump unit containing a pair of piston pumps and inlet and outlet valves from each piston pump. The inlet valves are coupled to the reservoir of beverage concentrate and the outlet valves are coupled to a mixer. A control valve introduces diluent to the concentrate intermediate the outlet valves and mixer and a reusable pump drive operates the piston pumps. The control valve and pump drive are operated by a control system in a manner such that a predetermined ratio of diluent to concentrate is delivered to the mixer. Downstream from the mixture the admixture of diluent and concentrate is dispensed as a beverage into a cup.

Office water cooler adapter for use with bagged fluids
A fluid dispensing apparatus comprises a collapsible bag capable of being punctured by and essentially sealed about a spike that has an inlet through which fluid can flow from the bag into a conduit leading to a chamber that is situated within an enclosed chamber in a dispensing base unit. The chamber is connected to a valve positioned outside the enclosed chamber through which fluid can be dispensed from the chamber. The enclosed chamber is vented so that as fluid is dispensed from the chamber, the air pressure in the enclosed chamber is allowed to equalize with the ambient air pressure external to the chamber and the bag.

Pump dispenser and cartridge
A cartridge for use in conjunction with a container to dispense a liquid in the cartridge into the container. The cartridge is comprised of a hollow body defined by an enclosing wall that has a closure at an upper end and a lower cartridge wall that is integral to the hollow body, but of a thickness less than that of the hollow body enclosing wall. The lower cartridge wall of a reduced thickness is in a narrowed section of the hollow body. A closure is sealed onto an upper part of the hollow body and has a funnel-like shape with a lower funnel wall. The funnel wall is of a reduced thickness as compared to the remainder of the closure. A flange on the hollow body rests on a container upper surface to support the cartridge on the container. A container closure will hold the cartridge in place during use. A dispensing pump on the container closure has a dip tube which pierces the funnel wall and cartridge wall and thereby dispense the cartridge contents into the container. The cartridge usually remains held onto the container until the contents of the container are depleted. The container will contain a diluent liquid for diluting the cartridge contents to the use concentration.

Container with air intake mechanism
An one-mouth container for storing liquid capable of preventing pulsating flow and controlling a discharging speed approximately at a constant independently of the amount of an internal liquid in the container when the internal liquid is discharged, in which a blow-molded portion ( 23 ) is formed on the container body side portion of a container mouth portion; a narrowed portion ( 24 ), a discharge port ( 31 ) and an air channel ( 11 ) extending from a side wall of the blow-molded portion ( 23 ) to a space at an upper part of the container body are formed by narrowing down the narrowed portion; the air channel has such a length that air supplied through the air channel ( 11 ) is released directly in the internal liquid; and both a discharge port ( 31 ) and an air port ( 25 ) are formed at the narrowed portion ( 24 ).

Drip resistant dispensing nozzle
A dispensing nozzle method and apparatus is provided that may help in reducing the number of defects in integrated circuits during the manufacturing process. In one embodiment, the nozzle is configured such that at least a portion of the end of the nozzle that dispenses fluid can increase and decrease with a change in pressure, which may help to control fluid drips when the nozzle is not dispensing.

Combination dispenser and frame
A dispenser for dispensing materials is provided including a container for holding the material to be dispensed, a plurality of frame portions for holding decorative items, locking apparatus for locking the frame portions to the container, and a dispensing means for dispensing materials from the container. The dispenser also includes a base for receiving the container and frame portions, a memory device for playing a sound when the dispenser is removed from the base, and a switch for activating the memory device when the container is removed from the base. The plurality of frames each contain an aperture and each aperture contains an inner edge operable to lock onto the container. The frames each contain clips to lock onto each other and hold the container. The dispenser includes a dispensing mechanism and the base includes an opening for receiving the dispensing mechanism. The dispenser may also include a cap for receiving the container and frame portions and a cover for covering the aperture may be included.
