ABSTRACT OF THE DISCLOSURE A feed tube assembly for a dispenser of potable liquid is described. The dispenser has a base with an inverted seat adapted to receive a neck of an inverted liquid container. The seat has a fluid flow channel extending therethrough in which the feed tube is positioned. The feed tube assembly includes a feed tube having at least one radial fluid flow passage. A guard sleeve is telescopically positioned on the feed tube. The sleeve is axially movable along the feed tube between a closed position obstructing the at least one radial fluid flow passage and an open position spaced from the at least one radial fluid flow passage. A contact surface extends outwardly from the sleeve. When a container is placed on the seat the container exerts a force upon the contact surface thereby moving the sleeve to an open position and exposing the at least one radial fluid flow passage to a flow of liquid from the container. The sleeve is maintained in the closed position when the container is removed thereby preventing the ingress of contaminants through the at least one radial fluid flow passage.
