ABSTRACT:
A closed loop dispensing system for use on a liquid container such as a bottle or the like for dispensing the liquid contents from the bottle. The outlet opening of the bottle is closed by a throat plug having a valve positioned therein which is open when the container cap is mounted on the container, but which automatically closes when the cap is removed from the container. An inlet opening is provided in the container insert so that liquid may be drawn therethrough. A closure cap is mounted on the bottle and has a dispensing tube extending therefrom for dispensing liquid from the container to a mixing machine or the like. A check valve is associated with the cap for preventing backflow from the dispensing tube to the container and for permitting liquid flow from the container to the dispensing tube in response to suction being applied to the dispensing tube. A precise discharge metering orifice is provided in the valve body as a substitution for proportioners which are normally located downstream of the dispensing system. A valve permits ambient air to enter the interior of the container as liquid is drawn therefrom. The valve prevents the flow of liquid therethrough.
