Refill device for dispensing a cosmetic product

Abstract

A device for refilling a first container, fitted with a threaded first neck and a vaporization head, includes a second container for a liquid, a connection component including a first bearing plate for engaging the first neck and a second bearing plate engaging the second container, a median wall including a central orifice, and a means of closing the second container or the central orifice. The connection component engages an axially movable component capable of sliding inside the connection component, to form a valve, the movable component being able to move, under the action of an axial constraint, from a closed position “F” to an open position “O”, or, under the action of a spring, from the position “O” to the position “F”. The movable component includes a radial projection for engaging the first neck so that the first neck exerts an axial constraint on the radial projection.
