Description

The present invention relates to an assembly for the massage and or dispensing of a cosmetic product contained in a container retained on a body of said assembly. Preferably, the massage is obtained by rotating the massage member of this assembly.

"Cosmetic product" means a product as defined in Council Directive 93/35 / EEC of 14 June 1993.

We know by the patent US 3,994,290 a massage device comprising a rotary massage unit rotated by a motor and carrying a plurality of freely mounted balls thereon. The massage device is mounted on a body also receiving a container containing a product that can be dispensed to said beads via a channel. The container has a unidirectional duckbill valve, the opening of which can only be obtained in response to a depression created in a chamber of the body adjacent to this valve. Such depression can be obtained in the chamber because of the relative sizes and shapes of the chamber and of said channel in communication with this chamber, in particular during the return of the container from a position partially depressed in said chamber to its initial position.

The patent application WO97 / 22326 describes a massage device comprising a handle at one end of which is mounted a rotatable piece relative to the handle. The moving part comprises a product reservoir whose wall forms a massage surface. The wall includes rotatably mounted balls that communicate with both the interior of the reservoir and the massage surface to bring the product from the reservoir to the surface. The reservoir is thus coupled to the massage surface so that when the massage surface is rotated, the reservoir containing the product also rotates. In addition, as soon as the massage surface is applied to the skin, the product is carried by the beads on the skin. This device does not allow to massage only without applying a product.

A problem posed by massage devices of the state of the art is that they are not easy to grip, and also that it is not easy to selectively dispense product or to control the rotational drive of the massage member.

In addition, the device described in the patent application WO97 / 22326 does not allow to independently change the product reservoir and the massage member.

• un récipient contenant ledit produit, notamment un produit cosmétique,
• un corps sur lequel est monté le récipient,
• un organe de massage monté sur ce corps,
• un moyen d'entraînement en rotation autour d'un axe de rotation dudit organe de massage relativement au corps et au récipient, et
• un conduit en communication fluidique entre une sortie du récipient et l'organe de massage,

caractérisé en ce que le récipient comporte un axe allongé entre ladite sortie et un fond du récipient, cet axe étant parallèle à l'axe de rotation.For this purpose, the invention relates to a set of massage and or dispensing of a product comprising

• a container containing said product, in particular a cosmetic product,
• a body on which the container is mounted,
• a massage member mounted on this body,
• means for driving in rotation about an axis of rotation of said massage member relative to the body and the container, and
• a conduit in fluid communication between an outlet of the container and the massage member,

characterized in that the container has an elongate axis between said outlet and a bottom of the container, this axis being parallel to the axis of rotation.

Another problem posed by massage devices of the state of the art is that they do not provide reliable and easy to implement solutions for the distribution of a product simultaneously or independently massage. In addition, with the devices of the state of the art product distribution is random when the container is no longer completely full.

Advantageously, the container is configured for packaging and dispensing a product under pressure, the conduit being connected to an outlet of a dispensing valve of the container.

The container may be arranged relative to the body so as to form a gripping member of the assembly. A closed bottom of said container, opposite the dispensing valve, can then form a gripping member.

An actuating member of the valve may protrude from the outer periphery of the body. This actuating member may comprise a lever arm. In particular, the actuation of the valve can be obtained by depressing the valve stem. Alternatively and or in addition, the actuation of the valve can be obtained by tilting or tilting of the valve stem.

For example, the duct may comprise a section parallel to the axis of rotation, and in particular a section of axis substantially coincident with the axis of rotation. During the rotation of the massage member, this duct section remains fixed which limits the problems of dynamic sealing. The container may comprise a main axis of elongation parallel to the axis of rotation of the massage member. In particular, the container may be mounted on the body at a first axially opposite end, relative to the axis of rotation of the massage member, at a second end of said body where the massage member is retained.

Advantageously, the container can be removably mounted on the body. The container may be snap-retained in a body cavity.

The container may comprise a wall delimiting inside it a compartment containing a product to be sprayed and a gas under pressure mixed at least in part.

Alternatively, the container may comprise two compartments of variable volume, a first compartment in communication with the valve and containing the product to be sprayed and a second compartment containing a propellant, the wall being impermeable to the product and the propellant.

Advantageously, the massage member may be removably mounted on the body. The massage member may have an application surface provided with at least one relief, in particular an eccentric relief, or a plurality of reliefs of different shapes and different heights

The massage member may comprise a removable tip having said application surface. The user can thus obtain different applications depending on the chosen massage member. For example, the massage member may comprise a foam tip when the massage has for example a slimming sight, or a tuft of hair when the massage is for example intended to replace the badger necessary to spread the shaving foam, or for cleaning the skin, or an abrasive application surface, for example obtained by inclusion of alumina particles in a resin or foam, when a micro dermabrasion of the upper layers of the epidermis or "peeling" is sought.

The massage member may comprise a structure retaining free balls in rotation in the housing of the massage member.

The massage member may comprise an elastically deformable portion, for example made in a closed-cell foam or in an elastomeric material, to tolerate the surface differences of the areas of the body to be massaged.

The application surface of the massage member may have a substantially rotational symmetry about an axis of symmetry, the application surface being rotated by the drive means about said axis of symmetry.

The drive means may comprise a motor, for example powered by a battery, for example a battery housed in the body or by the sector, controlled by a control member. The motor can drive the application member in rotation directly or indirectly, for example by means of movement transmission members, for example to reduce the speed of rotation and increase the torque.

The invention also relates to a massage member for rotatably and removably mounted on a body of an assembly according to the invention.

The invention also relates to a kit comprising an assembly according to the invention and a plurality of containers, the latter being arranged to be mounted selectively and removably on the body of this assembly. In such a kit, the containers preferably contain different products.

The kit may comprise a plurality of massage members, the latter being arranged to be mounted selectively and removably on the body of this assembly. Thus, according to for example the desired massage effect, the user selects the massage member comprising reliefs adapted to obtain this massage effect. In such a kit, the massage members preferably comprise different reliefs.

• fournir un kit comme enseigné ci-dessus,
• sélectionner un récipient,
• monter le récipient sélectionné sur le corps de l'ensemble,
• appliquer du produit sur le corps
• masser la zone du corps où le produit a été appliqué avec l'organe de massage entraîné en rotation.

The subject of the invention is also a cosmetic and non-therapeutic method for applying a product to a surface of the body, characterized in that it consists in:

• provide a kit as taught above,
• select a container,
• mount the selected container on the body of the assembly,
• apply product on the body
• massage the area of the body where the product has been applied with the massage member rotated.

In the context of such a method, preferably, the user selects a massage member to be mounted on the body of the assembly as a function of the selected container.

The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented only as an indication and in no way limitative of the invention. The figures show:

• Figure 1 : a partially truncated profile view of an assembly according to the invention;
• Figures 2 and 3 longitudinal sectional views of containers configured to be mounted in an assembly according to the invention;

The Figure 1 shows an assembly 1 according to the invention in which a massage member 2 is detached from a body 3 on which is mounted a container 4 adapted to distribute the product P it contains through the massage member 2 via the at least one duct 5 opening at an application surface 6 of this massage member 2 by at least one outlet orifice 7 of said massage member 2.

The container 4 is a device adapted to contain and distribute under pressure a product P, in liquid or pasty form. The container 4 is called "aerosol". Such a container 4 allows the product P to be propelled into the duct or channel 5 through the massage member 2.

The container 4 comprises a rigid outer enclosure 8, preferably of metal or plastic. It also comprises a dispensing valve 9 mounted generally on a cup 10 retained, for example by swelling, on the outer enclosure 8. The container 4 allows the continuous dispensing of the product P, with a continuous flow, during the phase where the valve 9 is kept open.

The enclosure 8 may contain the product and the propellant. In order to distribute the product, when the stem 11 of the dispensing valve 9 is actuated, it is necessary that the valve 9 is continuously supplied with product, for example by means of a dip tube, if the density of the product to be distribute is greater than that of the propellant and if the container is presented "head up", namely with the valve 9 above the enclosure 8.

For example, in order to be able to dispense the product in any position, the product P to be dispensed and the propellant gas are separately packaged in the chamber 8 as shown on the drawings. Figures 2 and 3 , the container 4 can then be of the type of those taught in the document FR-2841159 .

To do this, as shown Figure 2 the product can be packaged in a pocket 12 with flexible walls, in communication with the dispensing valve 9. A propellant G2 is packaged in a volume formed between the outer surface of the pocket 12 and the inner wall of the outer enclosure 8 The interior volume of the pocket 12 defines a first compartment 14 and the volume of the enclosure 8 outside the pocket 12 defines a second compartment 15.

Alternately, Figure 3 , the product P is kept separate from the propellant gas G2 by means of a piston 13 able to slide in sealed support against the inner surface of the outer enclosure 8 so that the container 4 is separated into two compartments, a first compartment 14 , in communication with the dispensing valve 9, containing the product P and a second compartment 15, between the piston 13 and the bottom of the container, containing the propellant gas G2.

To dispense the product with such devices, it causes the opening of the dispensing valve 9, by depression and or tilting of the rod 11 protruding from the body 16 of the valve 9. The body 16 of the valve 9 is in position fixed axial relative to the outer enclosure 8 insofar as it is retained in the cup 10, for example by crimping, the cup 10 also being fixed axial position relative to the enclosure 8.

When the dispensing valve 9 is open, the pressure exerted by the propellant G2 on the bag 12 or the piston 13 acts and presses the product P by the dispensing valve 9 out of the pocket or the first compartment.

The product P can then be distributed in the form of a paste, in particular cream or gel, liquid, spray or in the form of foam.

In the first compartment 14 or inside volume of the bag 12, the product P to be sprayed can be mixed with a first propellant G1 or a solvent with a high vapor pressure, while the second compartment contains the second thruster G2, the wall of the pocket 12 or the piston 13 being impermeable to the product and the thrusters.

The first propellant G1 is chosen for example from hydrocarbons or dimethyl ether, alone or mixed. The second propellant G2 is for example a compressed or liquefied gas, for example a mixture of propane, butane and isobutane, or compressed air.

The pocket 12 may be made of a metalloplastic complex, in particular an alumino-plastic complex comprising an aluminum layer and at least one layer of a thermoplastic material, in particular a polyamide, a polyethylene, a polyethylene terephthalate or a polypropylene.

The container 4 is designed to be removably mounted in the body 3. It is for example provided to be retained by clamping or snap-fastening with complementary means provided on the inner periphery of a cavity 17 formed in the body 3. In particular, these means cooperate with an annular bead formed by the junction between the cup 10 and the external enclosure 8.

The massage member 2 forms a tip 40 having the application surface 6, this tip 40 being retained on a support 41. The tip 40 may be removable relative to the support 41, and for example retained by means of type to bayonet on this support 41. Alternatively the tip 40 can be retained by snapping on the support 41. Figure 1 , the tip 40 is integral, for example glued or heat-sealed, to the support 41.

The massage member 2 is provided to be rotated relative to the body 3 by drive means provided inside the body 3. The drive means comprise a motor 19 powered by a battery 20, the battery 20 being connected to a control member 21 making it possible selectively to authorize or not powering the motor 19, and consequently driving the massage member 2 into rotation or not. The battery 20 is formed by at least one battery, even several batteries, housed in the body 3. Alternatively, the motor 19 may be powered by the sector.

The control member 21 can make it possible to select different rotational speeds of the motor 19. The control member 21 can form an electrical switch provided with a rotary selector protruding from the body 3 so as to be able to be respectively placed in three positions: a first off position, a second position corresponding to a first rotational speed, and a third position corresponding to a second rotational speed. In particular, the control member 21 may comprise a continuous variator of the speed of rotation of the motor 19 for a finer adjustment of the desired massage, and in particular according to the massage member 2 set up and / or the surface of skin to massage.

The motor 19 rotates a toothed wheel 22 cooperating with a set of gears 23 transmitting the movement to the massage member 2. Indeed, the massage member 2, and more particularly the support 41 has a toothed surface ( not shown) cooperating with one of the gears of the gear system 23. The gear assembly 23 forms a means for reducing the speed of rotation of the massage member, the gear 23 for increasing the torque.

The toothed surface is annular and traversed at its center by the channel 5. The channel 5 is partly formed inside a tube 25 disposed in the body 3, a first end 26 is connected to the end of the valve stem 11 through which the product P is dispensed. At a second end 27, the tube 25 is in engagement with a mounting skirt (not shown) of the massage member 2, and more particularly of the support 41. This mounting skirt is internal and concentric with the toothed surface, it is in fluid communication with the outlet port 7. Indeed, the mounting skirt opens into an interior space 29 of the massage member 2, this interior space 29 being formed for example between the support 41 and the tip 40 , so that the application surface 6 is traversed by at least one supply channel 30 connecting the interior space 29 to the outlet port 7. As shown Figure 1 the application surface 6 is traversed by a plurality of feed channels such as part in the inner space 29 and on the other hand by as many outlets as 7.

The axis X around which the massage member 2 is rotated corresponds preferably to the axis of symmetry of revolution of the inner periphery of the mounting skirt and the outer periphery of the portion of the tube 25 located between the ends 26. and 27. Between the ends 26 and 27, the channel 5 forms a first section elongating along the axis of rotation X.

When the massage member 2 is driven in rotation, the mounting skirt is rotated relative to the tube 25 which remains stationary in rotation relative to the body 3. For this purpose, it is possible to provide an annular ring between the tube 25 and the mounting skirt to maintain the tightness of this connection even when one is rotated relative to the other.

According to a variant not shown, the tube 25 may be flexible so as to bypass if necessary the parts provided in the body 3.

The assembly 1 is provided so that the product distribution P can be obtained independently of the rotational drive of the massage member 2. In the assembly 1 according to the invention, the X and Y axes are parallel to each other . The container 4 is then retained at one end of the body 3 axially opposite the end at which the massage member 2 is mounted. In this case, the actuation of the valve 9 is obtained by depressing, and this depression is in particular obtained by relative displacement of the container 4 relative to the body 3, insofar as the tube 25 is here in fixed axial position inside the body 3.

To obtain the product distribution with such an assembly 1, the user grasps with one hand the outer periphery of the body 3 and with his other hand the outer periphery of the container 4 to bring them closer together. Alternatively, the user can apply the application surface 6 against a skin area to be treated, and then depending on the gripping area he chooses, he can selectively distribute the product or not. Indeed, if the user grasps the outer periphery of the body 3 when the application surface 6 is applied against the skin, then the container 4 remains in fixed axial position relative to the body 3, and the valve 9 remains closed. There is no product distribution.

On the other hand, if the user grasps the outer periphery of the receptacle 4, the receptacle 4 may be partially seated in the cavity 17 of the body 3, and the valve 9 may be made to open and then allow dispensing of product, depending on the force with which the application surface 6 of the assembly 1 is applied against the skin.

When the user grasps the container 4 at its outer periphery protruding from the body 3, and to ensure that only a translation movement of the container 4 relative to the body 3 is allowed, the container 4 is provided with a flange 36 to guide and possibly limit the displacement of the container 4 relative to the body 3. This collar 36 cooperates with the side wall 35.

The side wall 35 of the container 4 is preferably cylindrical, the container 4 having a bottom 37 axially opposite, relative to the Y axis, to the cup 10 carrying the valve 9. The bottom 37 is closed. It optionally comprises a plug 38 to allow the second compartment 15 to be pressurized when the thruster G2 has to be injected via a syringe through this plug 38, Figures 2 and 3 .

In the embodiments of the invention, the bottom 37 and at least a portion of the side wall 35 protrude from the body 3. In particular, the portion of the side wall 35 projecting from this body 3 represents more than half of this area. side wall 35 relative to the main axis of elongation Y. Thus the bottom 37 and the portion of the side wall 35 form a gripping means of the assembly 1.

In addition, this portion of the container 4 visible, unmasked by the body 3, when the container 4 is mounted in the body 3, allows the user to read the indications of the product and or the recommended methods of use which may be inscribed on this side wall 35.

In particular, a method of implementing this assembly 1 is useful to know when the assembly 1 is not completely assembled and ready for use, in particular when it is supplied in the form of a kit 100, Figure 4 , possibly with several massage members such as 2 having different application surfaces selectively and removably mounted on the body 3, and with a plurality of containers such as 4 having different products, these containers being selectively mountable and Removable way on the body 3.

The method for applying a product to a surface of the body to be treated by means of this set 1 may consist of selecting a massage member such as 2 depending on the product contained in the container 4 which has been selected, to mount this massage member on the body 3, and bring the valve 9 in the open position so that the product is dispensed at the application surface 6 to be applied to the body. Then, simultaneously or not with the product distribution, the user can massage the area of the body where the product has been applied with the massage member rotated.

In particular, massage members adapted to be mounted on the body 3 to be rotated may have different application surfaces. They may have reliefs and / or a surface condition allowing the user to massage and / or clean the skin.

Application surfaces such as massage members may be made from natural or synthetic fibers (woven, nonwoven, wadding), natural or synthetic sponge, or from a variety of materials. The massage members may also be impregnated with a second product, for example having antimicrobial or coloring properties.

In the embodiment shown, the application surface 6 is formed from a block of thermocompromised foam optionally covered with a textile, having reliefs 39 arranged in a regular manner over the entire application face 6. In particular they are arranged in two concentric lines L _e and L _i , circular, centered on the axis of rotation X. Such an organ application is for example obtained in accordance with the teaching of patents FR-2,674,183 and FR-2,811,872 . Some of the reliefs may be traversed by a channel such as 30. In particular, in the case where the application surface 6 is fed by several channels such as 30, these can also open at a distance from the reliefs such as 39. The reliefs such as 39 form in this example domed bosses.

In particular, the application surface 6 of the massage member has a symmetry substantially of revolution about an axis of symmetry superimposable on the axis of rotation X.

As a variant, the application surface 6 is provided with a single relief such that 39a is eccentric relative to the axis of rotation X when the massage member 2 is mounted on the body 3, Figure 5a .

Alternatively, the application surface 6 comprises a plurality of reliefs such as 39 of different shapes and different heights, as shown Figure 5b .

Figure 5c , the application surface 6 can be presented on the removable tip 40 relative to the support 41 adapted to be retained on the body 3, the support 41 and the tip 40 together forming the massage member 2 can be rotated . Endpieces such as 40 adapted to be mounted on the support 41 may have respectively different application surfaces. In this example, the tip 40 has a groove 42 adapted to cooperate by snapping with a groove 43 on an inner periphery of a skirt 44 of the support 41. The skirt 44 extends in a direction opposite to the mounting skirt .

This tip 40 may be made of foam, or in an elastically deformable material, especially an elastomer, for example a PVC, PU, EVA, Nitrile, Silicone, butyl SEBS, EPDM, etc..

Preferably, the application surface 6 comprises an elastically deformable portion, for example made of elastomer, to impart a comfort when applying on the skin. It may be at least partially made from elastically deformable material such as PVC, PU, EVA, Nitrile, Silicone, butyl SEBS, EPDM, etc.

In a variant, Figure 5d , the massage member 2 may comprise a structure retaining free-running balls 45 each respectively in housings 46 of the application surface 6 of the massage member 2.

Alternately, Figure 5e , the application surface 6 may have a tuft of bristles 47 intended to be applied against the skin area to be massaged. The massage member can then be used as a shaving brush to form foam with the product spread on the face, prior to shaving.

In a variant, when the purpose of the massage is to clean the skin in depth, the application surface 6 may be abrasive, for example obtained by inclusion of alumina particles in a resin or a foam.

Throughout the description, the phrase "having one" should be considered synonymous with "having at least one", unless the opposite is specified.
