This adjustable metered liquid dispenser has a nonflexible trap chamber set for a predetermined volume and a one-way valve system. This system permits only a metered amount of liquid to flow from the container, and allows various amounts when measured to the lines on the chamber.

A key aspect of this design is that the liquid can be dispensed in any orientation, from horizontal to completely inverted, while maintaining a controlled amount of liquid. This makes the dispenser especially useful for delivering accurate doses of infant or children's medications, or other liquids where precise measuring is required.
