A NOZZLE AND A DISPENSER HAVING SUCH A NOZZLE

摘要

A nozzle for generating a spray of liquid has an outlet with a tapered protrusion (12) and two or more outlet orifices (14) which open through a sloping side wall region of the tapered protrusion (12). The tapered protrusion (12) and the orifices (14) are configured so that a portion of the liquid (15) emitted from each outlet orifice atomises to form a spray (15A) whilst a further portion of the liquid emitted from each orifice flows along the tapering surface towards a distal end of the protrusion where the liquid from all the orifices combines to form a core jet (15B) which streams from the distal end of the protrusion for a distance before atomising (15C). The tapered protrusion (12) has an angle of inclination in the range of 40 degrees to 80 degrees and the axis of each of the outlet orifices diverges outwardly from a longitudinal axis of the protrusion by no more than 10 degrees and preferably by no more than 5 degrees. A liquid dispenser comprising the nozzle is also described and claimed.
