ABSTRACT:
A fluid dispenser includes a cylindrical body which is open at one end and which has an opening in its side wall adjacent the other end to communicate with fluid material inside a container in which the dispenser is mounted. A second cylinder having openings in opposed side walls is slidably mounted within the body and is connected to a plunger for axially moving the inner cylinder which is normally biased inwardly so that fluid material may pass into the interior of the inner cylinder. As the plunger is activated, a closure member first slides under the opening in the cylindrical body to prevent additional material from leaving the container. Further movement of the plunger pushes the end of the inner cylinder out of the body of the dispenser to expose the opening in the side wall to thereby dispense the fluid material which had been in the interior thereof.
