The assembly comprises a pair of substantially identical unitary plastic molded units, each unit having a tubular stem formed with a piston at one end and a nozzle head at the other. Each unit has a female snap-type connector facing to one side and spaced therefrom a male snap-type connector facing to the same side, the molded units being disposed side-by-side with the male snap-type connectors snappingly received into the female snap-type connectors of the respective stems.

Piston/nozzle assembly for simultaneous pump dispenser

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.

Nozzle for pump dispensers

A tulip-type check valve is housed in a cylindrical chamber, the length of which is greater than the check valve itself so that during the pressure stroke of the pump, the valve moves forward in its chamber and flexes to permit flow about its periphery. During the suction stroke, the valve closes and is drawn backward upstream in its chamber and there is a sucking back of liquid between the check valve and the orifice to obviate nozzle the drip.
