Abstract: A squeeze container has a flexible and resilient sidewall and a top mouth closed by a cap through which a measuring tube extends into the container to terminate adjacent the container bottom wa1. A normally-closed check valve is fitted to the tube bottom end to allow liquid in the container to enter the tube in a measured quantity when the side wall is squeezed and for retaining the measured quantity of liquid when the tube sidewall is released. The measured liquid in the tube is discharged when the container is inverted and squeezed. After liquid discharge, outside air is admitted within the container to nearly re-establish atmospheric pressure, either through the measuring tube or through a check valve located at the cap. In the first case, the measuring tube check valve is not hermetic when closed, so as to permit air entrance at a slow rate.
