ABSTRACT:
A pump dispenser has a nozzle body on which is rotatably disposed a nozzle cap having two orifices which selectively align with a swirl chamber formed in the front end of the body. One orifice is formed with a surrounding cup-like structure to retain the last drop of liquid after discharge. The other is formed with a pair of diagonal parallel ribs on opposite sides of the orifice to effect an elongated narrow landing pattern for the spray.
