Description

RECHARGE DEVICE FOR DISTRIBUTING A COSMETIC PRODUCT

THE INVENTION

  The invention relates to the field of distributors of cosmetic products, in particular the field of perfume distributors. The invention relates more particularly to the field of refillable dispensers.

STATE OF THE ART

  Refills of perfume bottles typically consist of containers or flasks comprising a threaded neck, closed by a threaded plug.

  Likewise, refillable dispensers typically include a spray head threadably attached to a vial having a threaded neck.

  To refill the dispenser, the usual way to proceed is to unscrew the spray head and manually transfer the contents of the refill, after unscrewing the cap.

  The use of a refill is justified to the extent that, by its quality and its price, the distributor head is a non-disposable object.

  On the other hand, the value of a rechargeable refill relies more on the value of its contents than on the container forming the refill, so that, being of low intrinsic value, the refill of the dispenser is typically discarded or recycled. times empty.

PROBLEMS POSED

  This usual way of proceeding is not without problems.

  Indeed, given the fact that the neck of said refillable dispenser is typically small, it requires a certain address or manual skill to perform the transfer or transfer of perfume from a refill bottle or nurse to the bottle of said dispenser.

  The usual consequences of a transfer, except to be very skilful, are on the one hand a loss of product contained in the refill, often a perfume of great price, and on the other hand, a risk of soiling clothes or hands , with the risk of having a stubborn and lasting smell associated with such an operation, the product or the perfume having been able to spread and impregnate a fabric.

  French Application No. 00 11082 discloses a system for filling a secondary Io bottle from a main bottle. But such a system has a certain complexity of both manufacturing and implementation.

  The plaintiff has therefore sought a means that is both economic and practical, that is to say easy to implement by any user, to avoid the inconveniences associated with the usual way of proceeding.

DESCRIPTION OF THE INVENTION

  According to the invention, the device for refilling a said first container, typically a perfume bottle, provided with a first typically threaded neck and a spray head, comprises: a) a container, called a second container, for containing a typically liquid product to be transferred into said first container, typically perfume, b) a cooperating means having an axial direction and forming a connection piece, typically sealed, of said first and second containers, said connecting piece comprising a first typically threaded base intended to cooperate with said first neck and a second base, typically threaded, cooperating with said second container or with a second neck, typically threaded said second container, said first base and second base being arranged on either side of said second container; a median wall, typically horizontal, comprising a central orifice, so as to confront said first and second econd bottlenecks, and to form a means for transferring said product contained in said second container to said first container, c) a means for closing said second container or said central orifice.

  It is characterized in that: 1) said connecting piece cooperates with a movable part axially able to slide inside said second neck in an axial stroke, said movable part being able to pass under the action of a constraint axial, from an "F" or closed position in which said central orifice is closed, to an "O" or open position in which said central orifice is open, then to pass, under the action of a return means, typically a spring (6), from said position "O" to said position "F", said movable part cooperating with said connecting piece so as to form a valve and so as to form said closure means, 2) said piece mobile comprises a peripheral portion forming a drive means, typically a radial projection, intended to cooperate with said first neck or its upper edge, said first neck or its upper edge exerting on said drive means or ladi radial projection said axial stress when said first neck cooperates with said first neck, typically by screwing said first neck into said first base, and approaches axially said medial wall, 3) said movable part comprises a central portion adapted to cooperate with said connecting piece for forming said valve.

  This combination of means solves the problems posed.

  Indeed, on the one hand, the transfer or transfer of product is limited to two elementary operations, with: unscrewing of the vaporization head in order to clear said first neck of said first container, said first container corresponding to the dispenser to be refilled then the simple screwing of said charging device to said first neck.

  From the moment when the user is able to perform these two simple operations, the result to be obtained, namely a transfer or transfer free of losses and free of soiling, is then reached automatically.

  On the other hand, the device according to the invention forms a valve which opens automatically as soon as the refilling device is screwed onto said first neck corresponding to the bottle to be filled, and which closes automatically as soon as it is unscrewed. the charging device, which is extremely convenient.
