Abstract: A hollow feed tube has a pair of generally radial openings adjacent the tip end thereof for dispensing water from an inverted bottle having a cap with an axially inwardly extending central recess. The feed tube is dimensioned to penetrate and sealingly engage the cap recess and disengage a sealing plug from the recess when the inverted water bottle is lowered onto the feed tube so as to expose the radial openings to water in the bottle. A conical diverter is disposed within the tip end of the hollow feed tube for intercepting bubbles of replacement air rising upwardly through the hollow feed tube and diverting the bubbles outwardly through one radial opening while water from the bottle flows inwardly through the other radial opening.
