Abstract
A liquid dispenser system uses a container that has a reservoir in the bottom of the container and an opening in the top of the container. The dispenser has a cover, which covers the opening in the container and a draw tube that extends from the cover into the reservoir. An end of the draw tube in the reservoir has a plurality of inlets. The average cross-section of the reservoir below the inlets of the draw tube is less than one fourth of the average cross-section of the rest of the container. As a result of the difference in average cross-sections, the invention reduces the amount of liquid that the dispenser is not able to dispense, which reduces wasted liquid. In a production environment, the reduction in waste results in a reduction in down time.
