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. A dip tube extends downwardly from the container insert and is in communication with the valve so that liquid in the bottle 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 low micron mesh filter is provided at the discharge end of the dispensing system for preventing contaminants from flowing therethrough. 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.
