ABSTRACT:
A dispensing device for dispensing measured doses of liquid during each dispensing cycle. A fluid-tight bottle is provided with a well at its bottom. A hollow shell fits in the well and includes an opening permitting flow of material from the bottle into the shell. A tubular stem extends from the shell through the top of the bottle and terminates in a dispensing spout. A vent tube exceeds from the interior of the bottle adjacent to the shell and terminates in an upper end located outside of the bottle. The vent tube is apertured inside of the bottle, and a shutter is provided to control the aperture exposure to adjust the level at which the liquid can rise in the shell.
