A portable liquid dispensing device which includes a liquid cartridge containing a prefilled desired liquid supported within the dispensing device. A dispensing mechanism is positioned within the device for engagement with the liquid cartridge for dispensing a desired amount of liquid from the liquid cartridge to an outlet exiting the device. An actuator button is also provided for actuating the dispensing mechanism and dispensing the desired amount of liquid through the outlet of the dispensing device. The dispensing mechanism includes a central shaft with a first end engaged with the actuator button, a second end is positioned adjacent the outlet, and a plunger assembly is supported on the central shaft intermediate the first and second ends for substantially sealed engagement with an internal surface of the liquid cartridge and central shaft to move the plunger assembly and liquid toward the outlet upon actuation of the actuator button. Upon deactivation of the actuator button, the central shaft slidably moves or retracts through the plunger assembly, without moving the plunger assembly.

The device for packaging and dispensing a product including a storage container (12) provided with at least one variable-volume compartment (22) containing the product, a pressurizing means (30) able to permanently pressurize the product contained in the compartment, and a dispensing head (14) having a mounting base (32) attached to the container. The dispensing head further includes a dispensing member (34) mounted inside the mounting base (32) with the ability to move in rotation, a piston (36) with the ability to move in translation inside the dispensing member (34) and able to delimit, inside the said member, opposing first and second metering chambers (60, 62), and at least first and second orifices (56, 58) formed on the dispensing member (34) and respectively able to be in direct fluidic communication with the first and second metering chambers (60, 62).

An exhaust valve assembly for a bottle attachment apparatus for handling liquids has a valve housing which forms a valve chamber having an inlet and an outlet, an exhaust valve body disposed on the inlet in the valve chamber, and a safety valve body disposed on the outlet in the valve chamber. The exhaust valve body is biased toward an exhaust valve seat, counter to the flow direction of the liquid and the safety valve body is biased toward a safety valve seat in the flow direction of the liquid. The safety valve seat is integrally molded on the valve housing.

A dispensing closure for dispensing a flowable product from a squeeze-type product container includes a closure body having an upper deck, an exit orifice, and a skirt configured to attach to the product container. A measuring reservoir is received in engagement with a lower surface of the upper deck. The measuring reservoir is filled with a measured dose of flowable product through flow ports when the container is inverted. A piston valve is slidably movable within the measuring reservoir between an open position and a closed position. The piston valve is movable from the open position to the closed position to dispense the measured dose of product responsive to pressure within the container induced by squeezing.

An attachment for a beverage container may include a cap configured to attach to an opening in the beverage container. The cap includes an opening. The attachment also include a tube passing through the cap. A beverage in the beverage container can flow through the tube and out of the opening in the cap. The attachment also includes a container attached to the tube and configured to hold a liquid. The container includes an opening to allow the liquid to flow from the container into the tube and out of the opening in the cap. The attachment also comprises a restrictor between the opening of the container and the tube, such that the liquid begins to exit the opening in the cap before the beverage begins to exit the opening in the cap.

A syringe assembly contains a fluid material, preferably two reactive fluid materials. The syringe assembly includes a syringe body having at least one barrel and a piston assembly movable within the barrel. An activatable plunger is in contact with the piston assembly effects dispensing movement of the piston assembly. The piston assembly includes an outer piston in sealed engagement with the barrel and an inner piston in sealed engagement with the outer piston. The inner piston is movable within the outer piston with and against the bias of a spring to maintain the inner piston in contact with the reactive material in the barrel upon thermal expansion and contraction of the reactive material.

An improved valve assembly having a material inlet, a metering chamber and a port. A valve element reciprocates within a valve passageway, such that in a first condition, a flow path is created for material to flow from the inlet to the metering chamber and the valve element forms a metal-to-metal seal of the flow path to the discharge port. The valve element then slides to the second condition, to unseal the passageway to the discharge port, and forms a metal-to-metal seal of the flow path to the inlet. A piston forces the material out of the metering chamber, and because the flow path to the discharge port is unsealed and the flow path to the inlet is sealed, the material is directed from the metering chamber, to the discharge port, where it can be dispensed as desired.
