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.

Abstract: A nonaqueous composition for external use on the skin including a strongly hydrophilic amphiphilic solid active ingredient-surfactant complex dissolved or dispersed as a particle having a particle size of 2 nm to 200 nm in an oil phase. A strongly hydrophilic amphiphilic solid active ingredient-surfactant complex dissolved or dispersed as a particle having a particle size of 2 nm to 200 nm in the oil phase can be prepared by: adding a strongly hydrophilic amphiphilic solid active ingredient to a water phase to obtain a water phase mixture; adding a surfactant to an oil phase to obtain an oil phase mixture; mixing the obtained water phase mixture with the oil phase mixture to obtain a water-in-oil emulsion; freeze-drying the water-in-oil emulsion to obtain a strongly hydrophilic amphiphilic solid active ingredient-surfactant complex; and dissolving or dispersing the obtained strongly hydrophilic amphiphilic solid active ingredient-surfactant complex in an oil.

Abstract: A refill for a container device for cosmetic product that includes a vessel configured to contain such a product, the vessel including a lateral wall. The lateral wall of the vessel has, over at least part of its outside surface, a member made of elastomer material connected to the vessel and which is at least partly in relief in relation to the outside surface of the lateral wall of the vessel. The refill thus formed is able to be held in a casing of suitable shape, by virtue of the members in relief of elastomer material formed on the outside wall of the vessel. The invention also relates to a casing for a cosmetic product container device including a casing and such a refill.

Abstract: A refillable cosmetic product container device that is configured to receive a refill configured to contain the cosmetic product by an opening in order to put it in place in a reception volume defined by an inside wall of the casing. The inside wall has, over at least part of its surface, a member made of elastomer material connected to the casing and which is at least partly in relief relative to the inside wall of the casing.
