ABSTRACT A reuseable pressurized container and metering device for dis- pensing predetermined amounts of fluid. The device includes a metering chamber having two apertures with a central stem disposed therein. Two sealing rings are mounted on the stem, each adjacent an aperture, and are adapted to allow fluid to be forced into a reservoir through the metering device but are arranged to prevent the flow of fluids out of the metering device except when the stem is displaced by pressing a button attached at one end. One of the rings on the stem seals the metering chamber from an external charging and discharging passage and the other ring simultan- eously seals the metering chamber from the reservoir while the fluids contained within the metering chamber are being discharged, thereby limit- ing the quantity of fluid which can be dispensed. Following the discharge of all the fluids in the metering chamber, the button is released and one ring seals the metering chamber from the discharge conduit and the other is released to replace the metering chamber into communication with the reservoir. Additionally the stem can be set so as to provide for a con- tinuous flow of fluids from the reservoir through the metering chamber and out of the discharge passage. A plurality of telescoping inserts can be disposed within the metering chamber so as to reduce the volume, thereby reducing the quantity of fluid that can enter and thereby limit further the quantity of fluid which can be dispensed.
