  • These spiral-shaped mixing line guide 37 can also be implemented in a particularly compact design of the mixing device 30 ', 31'.
  • the inventive curved course of the respective mixing section 34, 37 can basically just not just as shown in the embodiments, d. H. realize two-dimensional but also spatially, d. H. three-dimensional. Above all, the three-dimensional curved course of the mixing section, wherein the curves not only run in a single plane, allows a more space-saving design of the mixing section 35, 35 'and the entire mixing device 30, 31, 30', 31 '.
  • the exemplary embodiments of the mixing device 30, 31, 30 ', 31' according to FIGS. 1-4 furthermore also have a straight mixing section 38, which on the one hand connects downstream to the curved mixing section 34, 37 and on the other hand terminates with the outlet opening 33.
  • This straight mixing section 38 is useful especially for the dispenser 1 shown for hair cosmetic product compositions, since such a straight mixing section 38 with nozzle-like outlet opening 33 allows a particularly accurate portioning and exact local application of the product composition.
  • FIGS. 1-4 illustrate the solution according to the invention using the example of a hair cosmetic dispenser 1 with a particularly user-friendly pressure vessel.

Abstract

L'invention concerne un dispositif de distribution ainsi qu'un distributeur (1) associé pour des compositions coulantes de produit, les différents composants de la composition de produit étant retenus séparément les uns des autres à l'intérieur du distributeur (1) jusqu'à la distribution proprement dite du produit. Pour simplifier la manipulation du distributeur (1), ce dernier comprend en conséquence un dispositif de distribution (10) qui sert à distribuer la composition de produit à plusieurs composants et qui présente un élément d'actionnement (11) servant à activer la distribution du produit, au moins deux ouvertures d'entrée (32) pour les composants du produit, au moins une ouverture de sortie (33) servant à distribuer la composition de produit, les ouvertures d'entrée (32) et l'ouverture de sortie (33) étant en liaison fluidique, et un dispositif de mélange (30, 31) agencé entre les ouvertures d'entrée (32) et l'ouverture de sortie (33), lequel comprend un parcours de mélange (35, 35') du type canal, à travers lequel les composants de produit peuvent circuler et présentant des chicanes d'écoulement (36), servant au mélange, provoqué par l'écoulement, des composants de produit. La longueur (L) du parcours de mélange (35) est supérieure à la plus grande dimension extérieure (I) du dispositif de distribution (10).
