Abstract

Le dispositif de distribution avec une cartouche pulvérisateur selon l'invention présente au moins un contenant ainsi que des accessoires tels qu'un mélangeur ou un bouchon de fermeture. La zone de fixation (6) de la cartouche (1) et la zone de fixation (20) des accessoires (2, 29) sont conçues de sorte que les accessoires puissent être placés sur la cartouche et, sans mouvement de rotation, être retirés par pression sur leur zone de retenue (20), des moyens de retenue sur une partie (1) coopérant avec des moyens de retenue sur l'autre partie (2, 29). Pour ce faire, la zone de fixation de la cartouche est munie au moins d'une première paire d'éléments de retenue (14, 15) situés sur des zones latérales opposées, qui ne sont pas prévus pour être sollicités en pression et ces parties de retenue coopèrent avec une première paire correspondante d'éléments de retenue (26, 26A; 30A, 30B) situés sur les accessoires. Dans des modes de réalisation plus perfectionnés, la zone de fixation peut présenter deux paires de moyens de retenue et les contenants de la cartouche peuvent être assemblés ensemble. De tels dispositifs de distribution peuvent être fabriqués de manière économique et sont simples à manipuler.
