Apparatus for dispensing squirts of liquid into the top openings of a moving train of regularly spaced-apart containers, including a rotating circular band having a plurality of nozzle openings spaced about it and aligned directly over the container top openings, and a fixed manifold device slidingly sealed to the band and supplied with liquid under pressure so that each time a nozzle opening passes the manifold it supplies a squirt of liquid into a corresponding container moving along beneath it. Automatic shut-off of the dispenser is provided in the absence of a container by sensing the absence of the container at an upstream position and automatically moving the manifold device axially out of alignment with the path of the nozzle openings to prevent squirting of liquid into a gap in the train. Another manifold slidingly sealed to the band is supplied with pressurized air so that each nozzle is blown clean of liquid immediately after it completes its dispensing action.
