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.
