• au moins un aimant 9 contenu dans un logement 11 présent dans le support 3;
• une tête d'application comprenant au moins une partie réalisée dans un matériau aimantable configuré pour être attiré par le ou les aimants 9, ladite tête d'application présentant une surface d'application supérieure à la moitié de la surface externe totale de ladite tête,

le dispositif 1 étant agencé de sorte que ladite tête d'application puisse être mobile en rotation dans le renfoncement 5.As illustrated on Figures 1 to 3 the application device 1 of a fluid comprises:

• a support 3 comprising a recess 5 having an apparent depth p;
• at least one magnet 9 contained in a housing 11 present in the support 3;
• an application head comprising at least one part made of a magnetizable material configured to be attracted by the magnet (s) 9, said application head having an application surface greater than half of the total external surface of said head,

the device 1 being arranged so that said application head can be rotatable in the recess 5.

In the application device of the invention 1, the application head is held solely by the magnetic force exerted by the magnet or magnets 9 on said head. The various elements forming the application device of the invention 1 are not used to hold the application head in the recess 5. They are therefore arranged to allow a large application area 10 which is greater than half the total external surface of said head. In other words, the majority of the surface of the application head is adapted and configured to be used to apply the fluid, particularly to the skin of the user.

The application surface of the application head corresponds to the external surface of the application head not facing the support 3. Thus, the application surface is in contact with the skin of the user to optionally deposit on the latter the fluid.

The device 1 of the invention is arranged to allow a better rotation of the application head in the recess and therefore a better use of said device 1.

In addition, because of this large area of application 10, a user can easily grasp the application head to remove it from the recess 5. The user can therefore simply and reproducibly remove the application head out of the device application of the invention 1 to clean or change, for example.

The application head may be at least one cylinder of circular cross section, and / or at least one element of revolution of substantially oblong or circular shape such as a substantially spherical ball. In the case of an application head comprising a plurality of cylinders and / or elements of revolution, one or more of said cylinders and / or one or more of said elements of revolution can be applied directly to the skin in order to massage the body. area of the skin on which he (they) is (are) in contact. In parallel, the other cylinders and / or the other elements of revolution may be intended to apply a fluid to the skin.

Each cylinder and each circular circular section revolution element, in particular each ball, typically have a radius greater than the apparent depth of the recess.

In the case of a ball, the application surface is formed by a portion of the ball whose angle at the top may be in particular greater than 180 °, in particular between 200 ° and 250 °, or substantially equal to 220 ° . In other words, the surface of the ball housed in the recess and therefore opposite the support corresponds to the surface of a cone with an angle α at the vertex strictly less than 180 °, in particular between 110 ° and 160 ° . In the case of a cylinder or an element of revolution with a substantially circular cross section, the angle taken is the angle at the center of each cross section, said angle taking the same values as the angle at the vertex mentioned above.

In the case of Figures 1 to 11 the application head is in the form of a ball 13 but may be in another form as mentioned above.

The application head or heads used to apply fluid and / or directly to the skin of the user can be smooth and polished finish, or textured appearance to provide various sensations during the massage and / or the application.

The fluid dispensed by the application device of the invention 1 may be a cosmetic or dermatological fluid. The viscosity of the fluid is adapted so that said fluid can spread over the surface of the ball 13. Thus, the fluid can be in the form of a gel or a cream. As a result, the application of said fluid takes place on the skin of a user, such as the face, the neck or any other part of the body.

As illustrated on Figures 1 to 3 , the application device of the invention 1 may be in the form of a means for dispensing the fluid without containing or storing the latter, such as a spatula.

In this case, as illustrated in figures 1 and 3 , the support 3 may be surmounted by an envelope 15 comprising a gripping portion. The envelope 15 may thus be made of a material capable of holding by welding, gluing, rimming or clipping on the support 3. The material may be for example plastic, metal or wood. As illustrated on the figure 1 , the support 3 may comprise at least one boss 16 configured to be locked in a complementary cavity 17 present on the casing 15 to prevent the casing 15 from sliding on the support 3.

In an illustrated variant on the figure 2 , the support 3 can be configured to form the gripping portion.

The support 3 may be formed of a single piece (see figure 2 ) or on the contrary of a multitude of pieces fitting one into the other.

As a result, the support 3 or the envelope 15 has a substantially conical shape with possibly one or more concavities 16 (see FIG. figure 3 ) or with a non-slip coating so that the fingers or the hand of a user can grip said part.

As illustrated on Figures 4 to 9 , the application device of the invention 1 can be integrated with a device for storing and dispensing the fluid which then comprises a receptacle 21 configured to contain the fluid. In this case, the support 3 can be configured to be mounted on the head 23 of a receptacle 21 arranged to contain the fluid.

The receptacle 21 may be of any shape, in particular a tube, a bottle or a sachet. The receptacle 21 may be made of any type of material, for example, glass, plastic or aluminum.

The application device 1 of the invention is configured so that the ball 13 can be rotatable in the recess 5. According to one embodiment, the ball 13 may be substantially in contact with the bottom of the recess 5. For in this case, the fluid is chosen so as to have an adequate viscosity to be able to spread over the surface of the ball 13 opposite the recess 5 in the manner of a lubricant, namely between the surface of the ball 13 and that from the bottom of the recess 5.

According to an illustrated variant on the Figures 1 to 11 , the recess 5 may comprise one or more elements in relief 7 generating the apparent depth p of recess 5, the device 1 being arranged so that the ball 13 can roll on the raised elements 7 in the recess 5. As a result, the element or elements in relief ensure a spacing e between the surface of the ball 13 opposite the recess 5 and that of said recess.

The raised element or elements 7 are then configured so as to allow a spacing e so that the fluid can flow between the ball 13 and the walls of the recess 5. The spacing e corresponds to the maximum height of the raised elements 7 relative to the wall of the recess 5. The spacing e may have a height of between 0.1 mm and 1 mm, in particular substantially equal to 0.4 mm.

The recess 5 may comprise in particular three elements in relief 7 arranged in the same plane and distributed at an angle substantially equal to 120 ° between them which allows to have the desired spacing e while allowing a stable base of the ball 13 in the recess 5 and therefore free rolling without friction of the ball 13 over the entire concave surface of the recess 5. As shown in FIG. figure 7 , the raised elements 7 in this embodiment form on the wall of the recess 5 a substantially equilateral triangle when viewed from the front said recess 5.

The raised elements 7 can be formed of material with the support 3 (see figure 4 ) or be reported on them (see figure 5 ), in particular via an envelope 25. The envelope 25 can thus be made of metal or plastic, for example.

According to these embodiments, the raised elements 7 may be formed by bosses made in the walls of the recess 5 (see figure 4 ) or by bosses made in said envelope 25 (see figure 5 ).

According to a variant illustrated in Figures 6 to 11 , the raised elements 7 may be formed by one or more rolling bearing balls 27 mounted free to rotate, or rolling, in the support 3, in particular in one or more cavities 28 of the support. To do this, said cavities 28 can be directly formed in the support 3. The bottom of the cavity or cavities 28 can be formed by one or more inserts 29 and 39 in the support 3 (see respectively the figure 6 and the Figures 8 to 11 ).

According to an embodiment illustrated in figure 6 said elements 29 may comprise at least one point-type boss 30 configured to to come into a corresponding cavity 31 of the support 3 in order to block the elements 29 in the support 3.

In a variant illustrated in Figures 8 to 11 , the ball or balls 27 are mounted free in translation, in particular along the central axis 41, so as to vary the apparent depth p of the recess 5. Thus, the ball or balls 27 can each be mounted on a insert 39 mounted on a magnet 9. The insert 39 is mounted free in translation in the housing 11 receiving the magnet 9. As a result, the ball or balls 27 can move up or down in the housing 11 so as to vary the apparent depth p of the recess, namely to give a spacing e between the ball 13 and the recess 5 adjustable between a maximum spacing and a substantially zero spacing in which the ball 13 can come to rest in the bottom of the recess 5 and ensure sealing. The insert 39 may translate along a length in particular between 0mm and 2 mm, in particular equal to 0.5 mm.

The ball or balls 27 may have a diameter of less than or equal to 4 mm.

The bearing ball or balls 27 may all have an identical diameter or different diameters.

The ball or balls 27 may be made of a metallic or plastic material, magnetizable or not. As an example of plastic, mention may be made of polypropylene, or else polyoxymethylene (POM). As an example of metal material, mention may be made of a polished stainless steel that does not require galvanization or a galvanized steel. Said steel can be treated by galvanizing by using in particular palladium as surface layer in finishing. The outer galvanizing layer is typically carried out in the absence of nickel to avoid the risk of allergy.

The seal can be achieved by an external clevis which at the end of screwing is able to press the ball 13 against the bottom of the recess 5 while allowing the closure of said recess 5.

To do this, the bearing ball or balls 27 may each be mounted on a spring or on a POM spring plate and are compressed. Each rolling ball 27 may be associated with one or more substantially hollow supports which allows greater flexibility.

The bearing ball or balls 27 may be replaced by one or more substantially perforated studs so as to provide greater flexibility. The studs can be monoblock with the support 3 which supports the application head.

A translation opening and closing system along the axis of the device 1 of the invention can be used. A ring or a click can activate this system.

The recess 5 typically has a shape substantially complementary to a portion of the ball 13. Therefore, the recess 5 has a substantially half-shell shape.

The apparent depth p corresponds typically to the actual depth of the recess 5 minus the spacing e generated by the relief elements 7, in the embodiment comprising such elements 7.

In the case where the ball 13 is substantially in contact with the bottom of the recess 5, the apparent depth p corresponds to the actual depth of the recess 5.

The radius R of the ball 13 is typically between 3 mm and 20 mm, in particular substantially equal to 6.35 mm.

At least a portion of the ball 13 is made of a magnetizable material configured to be retained by the magnet (s) 9 by a magnetic force. According to a variant illustrated in particular Figures 10 and 11 , the entire ball 13 is made of this magnetizable material.

The magnetizable material is, for example, a galvanized steel. When galvanizing, nickel is not used as an outer layer to avoid an allergic reaction. Palladium may be used as topcoat or surface of the ball 13 to ensure good compatibility with the fluid used, in particular a cosmetic or dermatological fluid. Typically, the deposited palladium layer may have a thickness substantially equal to 0.35 μm.

The application head, in particular the ball 13, can be full or hollow.

An application head, in particular the ball, can be made in any type of magnetizable metal or alloy, such as steel with or without a galvanizing coating or a magnetizable stainless steel, such as steel 420 , 430, 440, JFE443CT or JYH21CT. It is also possible that the application head, including the ball, full comprises a part made of a plastic material, in particular a plastic over-molding one or more magnetizable elements. The plastic material The application head, in particular the ball, may also be in the form of two half-elements, in particular two half-spheres, enclosing one or more elements made of a magnetizable material.

In order to reduce the weight of the application head, the application head, in particular the ball, can be hollow and be made by assembling one or more elements. Said elements may be in the form of two half-elements, in particular two half-spheres, glued, embedded in force or welded. The material used may be any magnetizable material such as a steel treated or not by galvanizing, or a magnetizable stainless steel, such as steel 420, 430, 440 or JFE443CT, treated or not by galvanizing.

In the case of application head, in particular ball, hollow made in a non-magnetizable stainless steel such as steel 304 or 316, the latter may contain one or more ferrous elements magnetizable. Thus, the application head, in particular the hollow ball, can be made in the form of two half-elements, in particular two half-spheres, made of anodized aluminum enclosing at its center one or more free magnetizable elements in motion.

Thus, the application head may be in the form of a plastic shell or metal, including aluminum, containing in its core metal element of smaller size. The use of aluminum shell allows anodization and easy coloring.

The application head may be an element made of a plastic comprising magnetizable ferrous material. As an example of plastic, mention may be made of polypropylene (PP) enriched with ferrous particles.

According to the variant illustrated in Figures 8 and 9 , the ball 13 may thus be in the form of a plastic ball 13a containing in its core a ball 13b of smaller metal diameter. The plastic ball 13a may be in the form of a double plastic shell, particularly reported welded.

The ball 13 may have a substantially smooth surface or on the contrary textured. By "textured" is meant a ball 13 having surface reliefs or irregularities or matte or satin finishes.

As indicated above, at least one magnet 9 is used to retain the ball 13. In particular, the application device of the invention 1 can have one or more magnets 9 of substantially cylindrical shape (see Figures 1 and 2 ) or toric (see Figures 4 to 6 ). According to a variant illustrated in Figures 8 to 11 , the application device of the invention 1 may comprise additional magnets 19 having an annular or ring-shaped section.

The magnet or magnets 9 may be arranged in the support 3 so as to have a uniform magnetic attraction on the ball 13 and thus allow the uniform retention thereof. To do this, the magnet or magnets 9 are mounted in the support substantially symmetrically with respect to the central axis 41 of the application device of the invention 1 passing through the center of the ball 13.

According to a variant illustrated in Figures 8 to 11 , the application device of the invention 1 may comprise a multitude of magnets 9 and 19, in particular of different sizes. Thus, the application device of the invention 1 may comprise three or more magnets which are arranged according to the distribution of the magnetic force generated by the magnets 9 and 19 which is desired.

The support 3 can be formed of a single block (see figures 2 and 5 ) or on the contrary of at least two blocks, also called "parts" (see figures 1 , 4 , 6 and 7 ). The upper part 3a of the support 3 forming the recess 5 is typically made in a single block in order to simplify the manufacture of the application device of the invention 1. The support 3 may comprise one or more lower parts 3b intended to be mounted on the head 23 of a receptacle containing the fluid.

Typically, the support 3 may be made of plastic material, such as polypropylene. The parts 3a and 3b forming the support 3 may be made of the same material or in different materials.

As illustrated on figures 4 and 6 , in the case where the support 3 is formed of two upper parts 3a and lower 3b, said parts 3a and 3b can be assembled by means of clipping preventing the rotation of the two upper parts 3a and 3b lower between them. Thus, the clipping means may comprise a projecting element 37 carried by the lower part 3b coming into a complementary cavity 38 provided in the upper part 3a defining the recess 5. It is also possible for the projecting element 37 to be carried by the upper part 3a and the cavity 38 by the lower part 3b.

The support 3 may be full or well behaved a multitude of housing some of which 11 may contain the magnet or magnets 9 and 19.

The support 3 can be surmounted by an envelope 25 to protect said support 3 and also to avoid the right angles 51 which induce discomfort for the user during the application of the fluid. For this purpose, the casing 25 may be made of aluminum.

In a variant not shown, the support 3 may comprise at least one boss configured to come to lock in a complementary cavity present on the casing 25 to prevent the casing 25 from sliding on the support 3.

As indicated above, the envelope 25 can support the raised elements 7.

Typically, the support 3 comprises at least one opening 55 for conveying the fluid out of the head 23 of the receptacle.

The support 3 may comprise holding means configured to cooperate with the head 23 of the receptacle to hold the latter in place during the application of the fluid by a screwing or latching system. In particular as illustrated on Figures 4 to 6 , the support 3 may comprise a screw thread 61 configured to cooperate with a screw thread 62 present on the head 23 of the receptacle. According to a variant, the retaining means may comprise a projecting element 63 configured to cooperate with a thread 64 of the head of the receptacle allowing quarter-turn latching, for example (see FIG. Figures 8 and 9 ).

As shown on figures 4 and 6 , the support 3 comprises a substantially peripheral ring 71 configured to come to lock on the side wall 73 of a cannula 75 of the head to ensure sealing. The cannula 75 is housed in a housing 77 provided in the support 3. Said cannula 75 may comprise one or more orifices 76 through which the fluid may flow which are arranged at the free end of the cannula 75.

According to a variant represented at figure 5 , the support 3 may include a cannula housing 81 having beveled corners 83 configured to rest on the free end of the cannula 75 to seal.

The support 3 may comprise a central orifice 91 for bringing the fluid to the ball. Said orifice 91 may coincide substantially with an opening of the head 23 of the receptacle or with a channel collecting the fluid from the head 23 of the receptacle.

The application device of the invention may also comprise a cover configured to close said device after use. The cover can be retained on the support or on the envelope by any means known to those skilled in the art, in particular by screwing, clipping or friction. The cover may typically be made of copolyester of cyclohexanedimethanol and purified terephthalic acid (PCTA) or polypropylene (PP). According to one variant, a cover comprising an outgrowth can be housed in the orifice of the cannula 75 in order to guarantee sealing after use. According to this variant, the ball 13 is previously removed from the recess 13.

Thus in the embodiments shown in figures 9 and 11 , the cover 101 is held on the application device of the invention 1 by friction, in particular on a fixed part of the application device 1 of the invention. In these embodiments illustrated in Figures 8 to 11 at least a portion of the magnets 9 are surmounted by the insert 39 which supports a rolling ball 27 which provides a spacing e sufficient to allow the fluid to flow on the surface of the ball 13. An envelope, ring-type , 35 is configured to rotate about the longitudinal axis 41 of the application device of the invention. More specifically, the rotation of the envelope 35 is made around the support 3, in particular the upper part 3a thereof. Such a rotation makes it possible to translate the insert 39 so that the rolling ball 27 moves away from the ball 13 to come into the closed position, as illustrated in FIGS. Figures 9 to 11 . Therefore, the ball 13 attracted by the magnets 9 is housed in the recess 5. Another piece configured to rotate around the central 41 and belonging or not to the support 3 can be used to ensure the movement of the insert 39.

In order to guarantee the seal, the recess 5 may comprise at the bottom a flat portion 105 preventing the fluid from flowing around the ball 13.

The cover 101 once mounted on the application device of the invention 1 can mechanically help to press the ball 13 into the bottom of the recess.
