Liquid Dispensing Assemblies includes a liquid supply line that extends into an ejection spout located above a fill chamber, closely adjacent the inner surface of a refrigerator door. The ejection spout defines a nozzle that is angled downwardly and rearwardly to direct the discharge path of the spout into a container placed in the fill chamber. This assembly to be coupled to a resilient-walled vessel includes a tip defining an unobstructed bore positioned to be in direct communication with the vessel when coupled to the vessel. The tip includes a valve structured to allow drop-wise liquid dispensing and to prevent liquid back flow at zero as well as near zero pressure differentials across the valve. The assembly also includes at least one vent opening structured to allow air into and out of the vessel. It provides a cap having an antibacterial liner. The combination of the filtration element, antibacterial liner in the cap and the ability of the valve to prevent back flow. It enables the solution in the vessel to remain sterile without preservatives.
