Title (EN) A NOZZLE AND A DISPENSER HAVING SUCH A NOZZLE
(FR) UNE BUSE ET UN DISPENSATEUR AYANT UNE TELLE BUSE
Abstract:
(EN) 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.
(FR) L’invention concerne une buse permettant de générer une pulvérisation de liquide ayant une sortie avec une projection effilée (12) et deux ou plusieurs orifices de sortie (14) qui s’ouvrent vers une région de paroi latérale pentue de la projection effilée (12). La projection effilée (12) et les orifices (14) sont configurés pour qu’une portion du liquide (15) émise de chaque orifice de sortie est atomisée pour constituer une pulvérisation (15A) tandis qu’une autre portion du liquide émise de chaque orifice s’écoule le long de la surface effilée vers une extrémité distale de la projection où le liquide provenant de tous les orifices se combine pour constituer un jet central (15B) s’écoulant de l’extrémité distale de la projection sur une distance donnée avant atomisation (15C). La projection effilée (12) possède un angle d’inclinaison dans la fourchette allant de 40 degrés à 80 degrés et l’axe de chacun des orifices de sortie diverge vers l’extérieur à partir d’un axe longitudinal de la projection sans dépasser 10 degrés et de préférence sans dépasser 5 degrés. Elle comporte également une description de dispensateur de liquide comprenant la buse, avec les revendications en annexe.
