Abstract
The present invention is a metered liquid squeezable dispenser, which includes a squeezable container having an open end and neck for dispensing liquid. A trap chamber base non-rotatably attached to the container and a trap chamber is rotatably attached to the trap chamber base. A dip tube is located in the base and extends into the container. There is an air inlet orifice located on the base. The trap chamber has a dispensing outlet, at least one metered dosage inlet pipe passing through the bottom of the trap chamber, extending upwardly therefrom for a predetermined height, and an air pipe passing through its bottom. The base and trap chamber align with one another for squeeze, metered dose filling, and then rotational realignment for squeeze dispensing.
