    [0001] The present invention relates to a unit for applying a cosmetic product to human keratin materials, in particular eyelashes or eyebrows. "Cosmetic product" means any composition as defined in Council Directive 93/35 / EEC of 14 June 1993. More specifically, the present invention relates to a cosmetic product application unit for an applicator comprising a dispensing zone. receiving the application unit, said application unit comprising: a substantially longitudinal support, said support comprising a first portion adapted to removably attach said support to the receiving area, and a second portion forming a less a receiving compartment of the cosmetic product; and a mass of cosmetic product to be applied to human keratin materials, said cosmetic product being different from a material forming the support. EP 1 955 610 discloses an applicator tip exclusively composed of an eyelash makeup composition, molded and adapted to be mounted by fitting on a heating medium having a finger shape. However, such a tip composed of a cosmetic product mounted directly on the heating support soiled this support which must be cleaned after each use. In addition, the handling of the tips composed solely of a makeup composition can cause a soiling of the fingers of the user. The Applicant has provided solutions to these problems by means of an application unit of the aforementioned type, in particular described in the document WO2011 / 131907. Such an application unit is typically manufactured according to a two-step injection molding process, as described in said document.
    [0002] However, the shapes of the present application units can cause deformation of the support at certain stages of the manufacturing process. In order to solve this problem, the invention relates to an application unit of the aforementioned type, in which an external surface of the mass of cosmetic product comprises at least one longitudinal bead extending continuously, substantially over the entire second portion of the support. According to other advantageous aspects of the invention, the application unit comprises one or more of the following characteristics, taken individually or according to all the possible technical combinations: the support comprises at least two separate receiving compartments others by ribs; - the ribs extend substantially transversely to the support, an outer surface of said ribs being partially covered by the longitudinal bead; the application unit comprises a longitudinal element connecting at least two transverse ribs, an outer surface of said longitudinal element being covered with cosmetic product; the support and the mass of cosmetic products are curved with respect to a longitudinal axis, the receiving compartments and the mass of cosmetic product being arranged in a concavity of the curvature. the outer surface of the mass of cosmetic product comprises two longitudinal beads, extending continuously, substantially over the entire second portion of the support, said two beads being arranged symmetrically with respect to a longitudinal plane of symmetry of the support. The invention also relates to a method for producing a cosmetic product application unit as described above, said method comprising the following steps: providing a first half-mold having a first impression and a second half-mold having a second cavity, the first and second indentations defining a first injection volume to form the support; injecting a first material into the first injection volume to form the support; dissociating the first and second half-molds, the support 20 remaining in the first cavity; providing a third half-mold having a third impression, the first and third imprints defining a second injection volume for forming the mass of cosmetic product; injecting cosmetic product into the second injection volume to form the mass. The third footprint has a groove for forming the longitudinal bead.
    [0003] According to other advantageous aspects of the invention, the method comprises one or more of the following characteristics, taken separately or according to all the possible technical combinations: a point of injection of the cosmetic product is substantially on a plane of longitudinal symmetry of the support; The third cavity comprises two grooves for the formation of two longitudinal beads, said grooves being arranged symmetrically with respect to a longitudinal plane of symmetry of the second injection volume. The invention furthermore relates to an assembly comprising: a unit for applying a cosmetic product as described above; and an applicator 35 comprising a heating receiving zone adapted to receive the application unit, the heating receiving zone being able to heat the mass of cosmetic product at a temperature inducing a change of state of said cosmetic product. The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example and with reference to the drawings, in which: FIG. 1 is a perspective view of a an assembly according to one embodiment of the invention; Figure 2 is a perspective view of an application unit according to one embodiment of the invention; Figure 3 is a longitudinal sectional view of the application unit of Figure 2; Figure 4 is a longitudinal sectional view of the application unit of Figures 2 and 3, during a first step of a manufacturing method according to one embodiment of the invention; Figure 5 is a cross-sectional view of the application unit of Figures 2-4 during a second step of said manufacturing process. Figure 1 on the one hand, and Figures 2 and 3 on the other hand, respectively represent two elements 10, 30 of an assembly for the application of a cosmetic product, according to one embodiment of the invention. Said assembly is particularly intended for the application of a cosmetic product to human keratin materials, in particular eyelashes or eyebrows. Figure 1 shows a heating applicator 10, similar to an applicator described in WO2011 / 131907. The applicator 10 comprises a handle 12 extending mainly along a longitudinal axis 14. The applicator 10 further comprises an applicator rod 16, which extends the handle 12 along the axis 14. A base is considered orthonormée (X, Y, Z), the axis 14 being parallel to the X direction. The rod 16 comprises a heating electric resistance, connected to a source of electrical energy housed in the handle 12. The rod 16 comprises for example a A metal tubular casing 18 enclosing an electrical insulating core (not shown), said core being traversed by a resistive electrical conductor (not shown) extending over the entire length of the casing 18. The electric heating resistor has for example a power nominal between 0.5 and 2 W and allows to reach a temperature above 50 ° C, for example a temperature of 70 ° C for an ambient temperature of 20 ° C.
    [0004] The source of electrical energy housed in the handle 12 is, for example, an electric battery. The heating is actuated by means of a switch 17 located on the handle 12. One end of the rod 16, opposite the handle 12, forms a receiving zone 5 of a cosmetic product application unit. In the embodiment of Figure 1, the receiving zone 20 has a curved shape in a plane (X, Y). The curve is substantially in an arc. Preferably, the curve has a radius of curvature of between 10 and 100 mm, more preferably between 20 and 30 mm, to best adapt to the application of the product on the eyelashes.
    [0005] Figures 2 and 3 show a cosmetic product application unit 30 according to one embodiment of the invention. The application unit 30 is able to be assembled to the receiving zone 20 of the applicator 10 of FIG. 1. The application unit 30 has an elongated shape and extends substantially along a longitudinal axis 32. When the application unit 30 is assembled to the receiving area 20 of the applicator 10, the axes 14 and 32 are merged. The same orthonormal base (X, Y, Z) is considered as in FIG. 1, the axis 32 being parallel to the direction X. The application unit 30 comprises a support 34 made of plastic and a mass 36 of cosmetic product P, carried by the support 34.
    [0006] The application unit 30, and therefore the support 34 and the mass 36, have a plane of symmetry (X, Y) containing the axis 32 and corresponding to the section plane of FIG. 3. The support 34 has the form of a tubular sleeve, in order to be able to be threaded on the rod 16 at the receiving zone 20. An inner wall 38 of the support 34 has a shape substantially complementary to an external shape of the metal casing 18, at the The support 34 has two longitudinal branches 40, 42, substantially disposed along the axis 32. At their ends along said axis 32, the longitudinal branches 40, 42 are connected by the proximal ends 44 and 42. The distal end 46 corresponds to the end furthest from the handle 12 when the application unit 30 is assembled to the receiving zone 20 of the applicator 10. The distal end 46 has a solid wall disposed in a plane (Y, Z). On the other hand, the proximal end 44 is open to allow the application unit 30 to be slipped onto the receiving zone 20 of the shaft 16. The longitudinal branches 40, 42 and the proximal 44 and distal ends 46 part of the inner wall 38 of the support 34, which allows the fixing of said support 34 removably on the reception zone 20.
    [0007] Furthermore, a frame formed by the longitudinal branches 40, 42 and the proximal 44 and distal ends 46 defines an area 48 capable of containing a cosmetic product. Preferably, the support 34 comprises a longitudinal slot 50, separating the longitudinal branches 40, 42. The slot 50 allows the support 34 to deform elastically by conforming to the shape of the receiving zone 20. In this case, an internal section the support 34 at rest is slightly smaller than a section of the reception zone 20. The slot 50 preferably extends over at least 50% of a length of the support 34 along the axis 32, more preferably at least 90 % of said length. The slot preferably extends in the plane of symmetry (X, Y) of the unit 30. The slot 50 has for example a width of between 0.5 mm and 1.5 mm, measured between the two longitudinal branches 40 and 42. In the embodiment of Figures 2 and 3, the support 34 is slightly bent in the plane of symmetry (X, Y) of the unit 30. The support 34 can thus marry the curvature of the receiving zone 20 as shown in Figure 1. The slot 50 is located on the side of the convexity of the curvature. On the side of the concavity of the curvature, the zone 48 of the support 34 comprises a series of ribs 52. Each end of the ribs 52 rests on a longitudinal limb 40, 42 of the support 34. In the embodiment of FIGS. 3, the ribs 52 are mutually parallel and oriented transversely, that is to say in planes (Y, Z). According to a variant described in the document WO2011 / 131907, the ribs 52 are inclined with respect to the planes (Y, Z). Preferably, the support 34 comprises between two and twenty ribs.
    [0008] Preferably, the support 34 has an even number of ribs, for reasons detailed below. In the example of Figures 2 and 3, the support 34 has sixteen ribs. A thickness of the ribs 52, measured in the X direction, is preferably between 0.5 mm and 1.5 mm.
    [0009] As seen in FIG. 5, in section along a plane (Y, Z), the ribs 52 of the support 34 have a crescent shape, between an internal profile 54 and an external profile 56. The internal profile 54 of the ribs 52 is part of the inner wall 38 of the support 34. In the example of Figure 3, the support 34 has a longitudinal dorsal 58 connecting the transverse ribs 52. The dorsal 58 has the shape of a wire disposed at the 35 of the internal profile 54 of the ribs 52. The dorsal 58 is part of the inner wall 38 of the support 34. The ends of the dorsal 58 are respectively connected to the proximal end 44 and the distal end 46 of the support 34. The dorsal 58 reinforces the structure formed by the transverse ribs 52. The dorsal has for example a substantially rectangular section in a plane (Y, Z), a side of the rectangle having for example a length of between 0.1 mm and 0.5 mm. In the example of FIG. 3, the dorsal 58 is disposed in the plane of symmetry (X, Y) of the unit 30. According to a variant not shown, the dorsal 58 is disposed in another plane (X, Y) . According to another variant not shown, the support 34 comprises at least two longitudinal ridges connecting the transverse ribs 52, said 10 dorsals being preferably parallel to each other. As can be seen in FIG. 3, two consecutive ribs 52 have crescent surfaces 60, 62 situated opposite one another in (Y, Z) planes. The dorsal 58 and the surfaces 60, 62 define compartments 64 for receiving a cosmetic product.
    [0010] The support 34 is for example made of plastic, in particular a polyolefin such as polyethylene (PE) or polypropylene (PP) or, alternatively, non-polyolefinic materials such as styrene-acrylonitrile (SAN), acrylonitrilebutadiene styrene (ABS) or polyoxymethylene (POM). These plastics are optionally filled with particles or mineral fibers, for example metal oxides, powder or fiberglass or carbon black, for example to improve and / or control the transfer of heat in the support 34 to the cosmetic product P and / or to improve the rigidity of the support 34. The mass 36 of cosmetic product P is integral with the support 34 on the side of the zone 48, the cosmetic product P being in particular received in the compartments 64 between the ribs 52. The mass 36 has an internal surface 66, in particular located between the internal profiles 54 of the ribs 52. The inner surface 66 of the mass 36 is continuous with the inner surface 38 of the support 34. The internal surfaces 38, 66 define a shape complementary to the external shape of the receiving zone 20 of the applicator 10.
    [0011] When the application unit 30 is assembled to the receiving zone 20, the inner surface 66 of the mass 36 is in contact with the casing 18 of the rod 16. The mass 36 also has an outer surface 68, intended to come into contact with the keratinous fibers. At the plane of symmetry (X, Y) of the unit 30, the outer profile 56 of the ribs 52 is flush with the outer surface 68 of the mass 36. At the level of said plane of symmetry, the ribs 52 are therefore visible since the outside the application unit 30.
    [0012] As can be seen in FIG. 2, the mass 36 also has two longitudinal beads 70, 72, forming part of the outer surface 68. The beads 70, 72 extend continuously in the length of the application unit. 30, substantially over the entire area 48 receiving the cosmetic product P. The beads 70, 72 of cosmetic product P cover the ribs 52, which are not visible from the outside at said beads. In the example of Figure 2, the longitudinal beads 70, 72 are arranged symmetrically with respect to the plane of symmetry (X, Y) of the unit 30. Other provisions of the beads are possible. According to variants not shown, the application unit 30 comprises a single longitudinal bead, or even more than two beads. The cosmetic product P forming mass 36 is, for example, an eyelash makeup composition having a property that varies as a function of temperature. Said property is for example a running character, in particular of dmax at 5 mm, d max being determined according to the protocol described in paragraphs [0120] to [0127] of document EP 1 955 610. The cosmetic product P is for example a composition comprising at least one reversible polymer that is solid at room temperature. By "solid" is meant a product that does not flow under the effect of gravity at 20 ° C. The cosmetic product P comprises, for example, at least one compound chosen from the following list: polymers and copolymers comprising at least one alkene monomer, in particular ethylene-based copolymers, polyvinyl acetate homopolymers, silicone resins, the film-forming ethylenic block polymers, which preferably comprise at least a first block and at least a second block having different glass transition temperatures (Tg), said first and second blocks being interconnected by an intermediate block comprising at least one monomer constituent of the first block and at least one constituent monomer of the second block, copolymers of dienes and styrene, sulfopolyesters, copolymers of alkene and vinyl acetate, in particular copolymers of ethylene and vinyl acetate; Ethylene-octene copolymers, vinyl polyacetate homopolymers, T-silicone resins, such as polyphenylsiloxanes, film-forming ethylenic block copolymers and derived essentially from monomers selected from alkyl methacrylates, acrylates, and the like. alkyl, and mixtures thereof, copolymers of butadiene and styrene, copolymers obtained by condensation of di-ethylene glycol, cyclohexane di-methanol, isophthalic acid, sulfoisophthalic acid, and mixtures thereof. Preferably, the cosmetic product P has a melting point greater than or equal to 50 ° C., for example close to 54 ° C.
    [0013] Preferentially, the support 34 carries a mass 36 comprising between 10 mg and 100 mg of cosmetic product P, more preferably between 20 mg and 50 mg of product, more preferably approximately 30 mg of product. This quantity is particularly suitable for a single use, for example to make up one or two eyelashes fringes.
    [0014] In the example of Figures 1 to 3, the receiving area 20 of the applicator 10 and the application unit 30 are bent as described above. According to a variant not shown, the receiving zone 20 and the application unit 30 have a substantially rectilinear shape along the axes 14 and 32. A method of manufacturing the application unit 30 will now be described, in 20 4 and 5. This is an injection molding process, similar to the method described in WO2011 / 131907. "Injection molding" means the molding of a part by injecting a material in a fluid state, at a pressure greater than atmospheric pressure, into a closed volume with the exception of an orifice of injection of matter.
    [0015] A device for manufacturing the application unit 30 comprises in particular a first half-mold 80 and a second half-mold 82. The first half-mold 80 comprises at least one first cavity 84. Preferably, the first half-mold 80 comprises a series of identical first impressions 84. The second half-mold 82 comprises at least one second cavity 86. Preferably, the second half-mold 82 comprises a series of identical second impressions 86. When the first half-mold 80 and the second half-mold 82 are placed in contact with each other as in FIG. 4, each first cavity 84 coincides with a second cavity 86 so as to define a first volume 88. injection of material to form the support 34.
    [0016] The second half mold 82 further comprises an injection channel 90 which opens on the second cavity 86 at a first injection point 92. As an example, the first injection point 92, shown in FIG. FIG. 2 is situated on the proximal end 44 of the support 34 in the plane of symmetry (X, Y) of the unit 30. Preferably, the second half-mold 82 comprises a series of identical injection channels 90, each of the channels opening onto a second cavity 86. In a first step of manufacturing the application unit 30, the first half-mold 80 and the second half-mold 82 are arranged in contact with each other . A material 94 in the fluid state is then injected into the first injection volume 88 via the injection channel 90, to form the support 34. As shown in FIG. 4, the first volume of FIG. injection 88 is then completely filled with material 94. The injection of the material 94 is preferably carried out at a temperature above 110 ° C for the material to be in the fluid state. Once the injection is complete, the assembly of the first half-mold 80 and the second half-mold 82 is cooled to solidify the material 94.
    [0017] The first half-mold 80 and the second half-mold 82 are then dissociated. The support 34, obtained by cooling the material 94, remains in the first cavity 84 of the first half-mold 80. The first half-mold 80 is then brought into contact with a third half-mold 96 as shown in FIG.
    [0018] The third half-mold 96 comprises at least one third cavity 98. The first cavity 84 coincides with the third cavity 98 so as to define, with the support 34, a second volume 99 for injecting cosmetic product P to form the mass. 36. As can be seen in FIG. 5, the third impression 98 has two longitudinal grooves 100, 102 for the formation of the longitudinal beads, respectively 70 and 72. The longitudinal grooves 100, 102 are arranged symmetrically with respect to the plane of symmetry (X , Y) of the unit 30. Preferably, the third half-mold 96 comprises a series of identical third impressions 98. When the first half-mold 80 and the third half-mold 96 are arranged in contact with each other as in FIG. 5, each first cavity 84 coincides with a third cavity 98 so as to define a second volume. 99. The third half-mold 96 further comprises an injection channel 104, shown in dashed lines in FIG. 5. The injection channel 104 opens onto the third impression 98 at a second injection point 106. By way of example, the second injection point 106, shown in FIG. 2, is located in the plane of symmetry (X, Y) of the unit 30, substantially equidistant from the proximal end 44 and distally 46. The support 34 preferably comprising an even number of ribs 52, an equal number of ribs 52 is preferably located on either side of the second injection point 106. In the example of FIG. 5, the second point injection 106 is located away from the rain In a variation not shown, the second injection point is located in a longitudinal groove. Preferably, the third half-mold 96 comprises a series of identical injection channels 104, each channel opening onto a third cavity 98. In a second manufacturing step of the application unit 30, the first half-mold 80 and the third half-mold 96 are arranged in contact with each other. The compartments 64 of the support 34, able to receive the cosmetic product P, are then delimited by the ribs 52, the dorsal 58, the first cavity 84 and the third cavity 98. The product P in the fluid state is then injected into the second injection volume 99 through the injection channel 104. The fluid product P first fills the compartment 64 positioned at the second injection point 106. Via the longitudinal grooves 100 , 102, the product P then successively fills, step by step, all the compartments 64 of the zone 48. The second injection volume 99 is then completely filled with product P. The injection of the product P is preferentially carried out at a temperature above 50 ° C for the material to be in the fluid state. In order not to melt the support 34 during the injection of the product P, the injection temperature of the product P is chosen to be lower than a melting point of the material 94. According to a variant of the process described above, the material 94 and the product P are injected into the first volume 88 and the second volume 99 by several injection points.
    [0019] Once the injection is complete, the assembly of the first half-mold 80 and the third half-mold 96 is cooled to solidify the product P, forming the mass 36. The first half-mold 80 and the third half-mold 96 are then dissociated. The unit 30 obtained is then ejected from the first cavity 84 of the first half-mold 80, by means not shown.
    [0020] During the injection of the product P, the diffusion of the product is effected by means of the longitudinal grooves 100, 102 formed in the half-mold 96. The product stream 3028732 11 P thus exerts little mechanical stress on the ribs 52. In contrast, in WO2011 / 131907, the product P passes from one compartment to another through a groove formed in the support at the base of the ribs. During the injection of the product P, the process described above thus generates less deformation of the ribs than the method of document WO2011 / 131907. Moreover, the presence of the dorsal 58 contributes to stabilizing the ribs 52 during the injection of the product P. The above characteristics therefore make it possible to reduce the percentage of units rejected at the end of the process due to deformation of the support. 34.
    [0021] The above method of manufacturing the application unit 30 is effected for example by means of a molding press (not shown) as described in WO2011 / 131907. A method of using an application set as described above will now be described. First, a user assembles an application unit 30 to the reception area 20 of the applicator 10, in particular by threading the support 34 on the rod 16 at the proximal end 44. application 30 is disposed on the receiving zone 20 so that the mass 36 of cosmetic product is located inside the curvature of said receiving zone 20. The user then presses the switch 17 of the handle 12. The temperature of the metal shell 18 increases, causing the softening or melting of the mass 36 of cosmetic product. In particular, the beads 70, 72 soften or melt. By holding the applicator 10 by the handle 12, the user then brings the receiving zone 20 closer to the makeup eyelashes. So that the curvature of the receiving zone 20 substantially matches the shape of the edge of the eyelid, the user positions his eye on the concavity side of said receiving zone 20, the axis 14 being disposed substantially perpendicularly to a plane of the eyelid. symmetry of the face. In Figure 1, such a plane of symmetry is a plane (Y, Z).
    [0022] The user then passes the mass 36 on his eyelashes. The product P, softened or melted, is deposited on the eyelashes. In particular, the product P forming the beads 70, 72 is deposited on the eyelashes. After use, the user easily removes the application unit 30 from the rod 16, by a reverse movement of the assembly movement. If necessary, a new application unit 30 is then assembled to the rod 16. Such a change of application unit can be made without waiting for the cooling of the rod 16.
    [0023] The assembly described above is for example marketed in the form of a kit, comprising on the one hand an applicator 10, and on the other hand one or more application units 30. According to a first variant, all the units of FIG. application 30 of the same kit are identical. According to another variant, two application units 30 of the same kit comprise a different support 34 and / or a mass 36 of different cosmetic product P. 10
