Abstract
Dispensing device for a cosmetic product stored in heterogeneous form including solid elements in suspension. The device includes a reservoir, a dispensing tip, a guide duct for transporting the product between the reservoir and the dispensing tip, and a product flow inducer configured to cause product flow from the reservoir to the dispensing tip. The guide duct includes a solid elements rupture configured to rupture the solid elements. The solid elements rupture includes a first stage at an exit from the reservoir forming a first portion of the guide duct and includes a changing transverse cross-section that has, at the exit, edges projecting within the guide duct. A second stage, near the dispensing tip, forms a second portion of the guide duct having a progressing cross-sectional restriction. The invention also relates to an assembly that includes such device and a cosmetic or care product that includes solid elements in suspension.
