  • This problem is particularly blatant with shaving foam or the like, but also occurs in non-foamed or non-intumescent products and can in particular lead to undesirable contamination of the dispensing devices.
  • WO 2007/104561 A2 discloses a dispensing device.
  • the dispenser has a dispensing head with an outlet space and a downstream outlet valve for preventing a subsequent escape of products. By depressing the dispensing head, the latter can open an associated dispensing valve of the dispensing device via a connection section, so that the product can be dispensed from the dispensing valve via the outlet chamber and the outlet valve.

Abstract

L'invention concerne un dispositif de distribution ainsi qu'une tête de distribution, et leur utilisation. Une soupape de distribution est ouverte par pression vers le bas de la tête de distribution, et le produit à distribuer peut sortir ou être distribué à travers un espace de sortie et par l'intermédiaire d'une soupape de sortie agencée en aval. L'invention vise à éviter, ou du moins à réduire au minimum, l'écoulement ultérieur de gouttes ou de mousse. A cet effet, le volume de l'espace de sortie est tout d'abord réduit lors de l'actionnement de la tête de distribution, puis à nouveau agrandi une fois l'actionnement terminé, en particulier une fois la soupape de distribution fermée, de sorte que le produit est à nouveau aspiré et revient dans l'espace de distribution par la sortie ou la soupape de sortie.
