ABSTRACT:
A vented housing has a tubular inlet for receiving liquid from a container and for venting the container. The housing provides a measured volume determined by the inlet position in the housing. An upper valve engages the inlet and a lower valve linked to the upper valve engages a discharge port for discharging the measured volume. The upper valve closes the inlet when the measured volume is dispensed through the discharge port. The upper valve is removable to provide a continuous pour mode. The upper valve when closed has a valve clearance sufficiently small to cut off vent action to the container to stop the flow of liquid through the inlet and sufficiently large to permit sliding action of the valve within the inlet without significant mechanical pressure contact between the valve and the inlet.
