Dispenser for a product in powder form

Abstract

The dispenser ( 1 ) for a product in powder form, typically a cosmetic product, includes a body ( 2 ) forming a cavity ( 20 ) intended to contain said product in powder form and fitted with an upper aperture ( 21 ), a means ( 4 ) for applying said powder, and a cap ( 3 ) intended to seal said upper aperture ( 21 ) via an engagement means ( 11 ), and is characterised in that: a) said engagement means ( 11 ) is selected in such a way that an axial and/or radial compression is exerted between said body ( 2 ) and said cap ( 3 ), and that said cavity ( 20 ) is thus typically leakproof when said dispenser ( 1 ) is closed, b) said cavity ( 20 ) includes a lower part ( 22 ) and an upper part ( 23 ) separated by a plate ( 5, 24 ) integral with said body ( 2 ) and fitted with orifices ( 50, 240 ), said lower part ( 22 ) containing said product in powder form, said plate ( 5, 24 ) allowing said product to move, via said orifices ( 50, 240 ), towards said application means ( 4 ), c) said application means ( 4 ) is a removable application means. Advantages: a dispenser straightforward in design, easy to miniaturise and to make leakproof.
