Abstract: A liquid dispensing apparatus for sequentially gravity feeding the liquid contents from a plurality of liquid containers into a closed manifold for selective dispensing therefrom. The manifold itself is disposed in a generally horizontal position and includes a plurality of individual container receivers extending generally vertically upward therefrom and in liquid communication therewith. Each receiver includes means for supporting a liquid container in an inverted, vertically disposed position with successive ones of the containers having their liquid outlets positioned at a different vertical level than the liquid outlet levels of the other containers. This arrangement permits the establishment of an initial steady state liquid level wherein all the container liquid outlets are at least covered by liquid to prevent further liquid flow therefrom. When a selected portion of liquid is removed from the manifold for dispensing or other use, the initial steady state liquid level is temporarily lowered so as to uncover the highest vertically disposed container liquid outlet. This uncovering permits air to flow into the container to facilitate liquid flow therefrom until the initial steady state liquid level is again reestablished to block further liquid flow. At all times during liquid dispensing from the manifold itself, replacement liquid is only drawn from the container having its liquid opening at the highest vertical level and which also has liquid therein. The arrangement further includes a normally closed flow valve associated with each container. A container support and sealing means is provided for each receiver to assure proper location and retention of the containers relative thereto.
