    Cosmetic product application device for keratin fibers, packaging and application unit and associated method
    The present invention relates to a device for applying a cosmetic product for keratin fibers, in particular for the eyelashes, intended to be immersed in a container of cosmetic product, of the type comprising:
    a heating support comprising a gripping member and a heating element along a longitudinal axis X from the gripping member, the heating element comprising a metal sheath,
    an applicator member comprising a sleeve extending along the longitudinal axis X, the sleeve being suitable for threading around the sheath, the applicator member comprising a plurality of separation / combing elements extending laterally projecting from the sleeve, the sleeve defining a plurality of through openings intended to bring the cosmetic product into contact with the metal sheath of the heating support.
    In particular, the heating element of the heating support further comprises a resistive wire placed inside the sheath and in thermal contact with an internal wall of the sheath.
    As a variant or in addition, provision may be made for the heating element of the heating support to comprise a plurality of discrete heating resistors distributed along and around the longitudinal axis, and in thermal contact with an internal wall of the sheath.
    By “cosmetic product” is meant within the meaning of the present invention a product as defined in Regulation (EC) No. 1223/2009 cLi European Parliament and of the Council dated November 30, 2009, relating to cosmetic products.
    The cosmetic product intended to be applied by the application device according to the invention is in particular in the form of a powder, a compacted solid, or a fluid such as a liquid. The product is advantageously a product intended to be placed on the keratin fibers of a user, such as the eyelashes. The product is for example a makeup product such as a mascara.
    It is known to apply a makeup product such as a mascara using a heating application device, intended to curl and / or lengthen the eyelashes. Document FR3035576 describes a heating application device of the aforementioned type on which an application member is fitted in the form of a comb.
    One of the technical and safety constraints weighing in the development of this type of heating mascara is that the heating element intended to come into contact with the mascara and potentially with the eyelashes (in this case the metal sheath) must be around 65 ° C - 70 ° C for, on the one hand, sufficiently heating the cosmetic product so that it is in its effective zone, and on the other hand, limiting the risks of eyelash, eyelid or other burns of the user.
    In order to bring the cosmetic product to a temperature as close as possible to the temperature of the hot element, it is known to provide access openings to this hot element through the application comb.
    However, this type of application device can still be improved. The presence of an asymmetrical comb requires dexterity on the part of the user in order to best position the application device relative to the eyelashes, so that the application of the cosmetic product is optimal. In addition, it is necessary to immerse the application device very regularly in the reservoir in order to refill it with cosmetic product.
    An object of the invention is to obtain a heating application device which is simple to use and which allows optimal application of the cosmetic product to the eyelashes.
    To this end, the subject of the invention is an application device of the aforementioned type, in which for any axial plane passing through the longitudinal axis X, the sleeve comprises at least a first separation / combing element and defines at least one first through opening on a first side of the axial plane, the sleeve comprising at least one second separation / combing element and defining at least one second through opening on a second side of the axial plane.
    Thus, thanks to the application device according to the invention, it is easy for the user to apply the mascara without having to seek a particular position of the application member relative to the eyelashes since the separation / combing elements and the through openings are distributed all around the applicator member. The applicator device of the application device according to the invention also allows greater autonomy of use without the need to recharge the application device repeatedly by immersing it in the product tank.
    According to an advantageous aspect of the invention, the separation / combing elements are aligned in a first plurality of rows, the through openings being aligned in a second plurality of rows, said rows of the first plurality and said rows of the second plurality being distributed around the longitudinal axis X, each row extending along a generatrix of the sleeve.
    The presence of rows of combing / separating elements and rows of through openings optimizes the application of the cosmetic product to the keratin fibers by improving the capacities of the applicator member in terms of loading of cosmetic product and performance. separation / combing of keratin fibers.
    According to variants, the applicator member comprises at least a first series of rows of separation / combing elements along which the separation / combing elements are spaced from each other by a first constant distance di and a second series of rows of separation / combing elements along which the separation / combing elements are spaced from each other by a second constant distance d 2 , d 2 being greater than dp
    As a variant, the applicator member alternately comprises a row of separation / combing elements belonging to the first series of rows and a row of separation / combing elements belonging to the second series of rows.
    Alternatively, the separation / combing elements of a row belonging to the second series of rows are staggered with respect to the separation / combing elements of the adjacent row belonging to the first series of rows.
    As a variant, at least one row of separation / combing elements and one row of through openings extend along the same generatrix of the sleeve, so as to have, along said generatrix, alternation between separating / combing elements and through openings.
    The arrangement of the separation / combing elements, in particular in staggered rows, creates a tortuosity, a baffle for the keratin fibers promoting the loading of cosmetic product by slowing down the fibers during their combing / separation. The separation / combing elements guide the fiber towards a through opening, so that it is loaded with cosmetic product.
    According to a variant, the through openings have a cross section whose larger dimension extends substantially in a direction perpendicular to the longitudinal axis X.
    The keratin fibers thus plunge as close as possible to the heating element and are loaded with cosmetic product heated to optimal temperature.
    Alternatively, the through openings have a diamond-shaped section, said diamond having a larger diagonal extending substantially in a direction perpendicular to the longitudinal axis X.
    The diamond shape of the through opening optimizes the number and size of the through openings on the applicator member. It also improves the implantation and the number of separation / combing elements on the applicator member. It allows improved dipping of the fiber in the cosmetic product.
    According to variants, the through openings have a first cylindrical projection pi on an internal surface of the sleeve and a second cylindrical projection p 2 on an external surface of the sleeve, the first projection p! having an area less than the area of the second projection p 2 . As a variant, the first projection Pi has a dimension ai along the longitudinal axis X and a dimension bi in a direction perpendicular to the longitudinal axis X and in that the second projection p 2 has a dimension a 2 along the longitudinal axis X and a dimension b 2 in a direction perpendicular to the longitudinal axis X, the ratio a 2 / a! being greater than the ratio b 2 / b !.
    The through openings are flared towards the external surface of the applicator member. The loading of the cosmetic product at optimal temperature on the keratin fibers is thus favored, the keratin fibers being caused to "plunge" inside the cosmetic product reserves constituted by the through openings as close as possible to the heating element.
    The invention also relates to a set of packaging and application comprising:
    - a cosmetic product tank,
    - An application device as defined above, the application member being suitable for being immersed in the tank to collect cosmetic product.
    The packaging and application assembly according to the invention is particularly suited to the needs of a user, since it comprises both the application device and the cosmetic product reservoir in which the application member can to be immersed.
    The subject of the invention is also a process for applying a cosmetic product to a keratin fiber, in particular an eyelash, comprising the following steps:
    - entry of an application device as defined above,
    - activation of the heating element,
    - collection of cosmetic product in a tank, the cosmetic product accumulating in the through openings,
    - impression of a rotational movement around the longitudinal axis X of the application device and / or a translational movement perpendicular to the longitudinal axis,
    - passage of a keratin fiber through a through opening and loading of cosmetic product onto the keratin fiber,
    - combing and stretching of the keratin fiber in a direction substantially perpendicular to the longitudinal axis X by means of the separation / combing elements located on either side of the through opening.
    The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example and made with reference to the appended drawings, in which:
    Figure 1 is a partial view, in exploded perspective, of an application device according to the invention, Figure 2 is a view taken in section along a vertical median plane of the application device according to the invention, Figures 3 and 4 are side views of the application member of the application device of FIG. 1, FIG. 5 is a longitudinal section along the plane V of FIG. 3, FIGS. 6 and 7 are respectively views in front end and rear end of the applicator member of Figure 3, and Figure 8 is a schematic cross section along plane VIII of the applicator member of Figure 3.
    Figures 1 to 8 show a partial view of an application device 10 according to the invention. The application device 10 is intended to be combined with a reservoir 11 of cosmetic product to form a packaging and application unit.
    The application device 10 is intended to apply a cosmetic product, in particular a cosmetic makeup and / or care product, in particular a mascara, to the keratin fibers of a user, in particular the eyelashes or the eyebrows.
    The application device 10 includes an application member 12. It also includes a heating support 14 on which the application member 12 is permanently or removably assembled.
    The heating support 14 has an elongated shape, extending substantially along a first longitudinal axis X. The heating support 14 comprises in particular a gripping member 18 in the form of a handle arranged along the longitudinal axis X. The support heater 14 also comprises a heating element 20, capable of heating the cosmetic product and / or the keratin fibers of the user, in particular the eyelashes or the eyebrows.
    The gripping element 18 comprises a proximal part (not shown) and a distal part 22, adjacent along the longitudinal axis X. In contrast to the proximal part, the distal part 22 has a distal end 24. L the distal end 24 comprises a mechanism for assembling the application member 12.
    The distal part 22 of the gripping element 18 is formed in one piece, in particular by a thermoplastic material. The distal part 22 has a shape of revolution around the longitudinal axis X. An internal wall of the distal part 22 has a cylindrical shape, defining a tubular cavity 26 which crosses said distal part 22 along the longitudinal axis X.
    An external wall of the distal part 22 has a shoulder 28 axially delimiting the distal end 24. Said distal end 24 has an external diameter smaller than the external diameter of the rest of the distal part 22.
    As described below, the applicator member 12 is suitable for being fitted on the distal end 24, to come into axial abutment against the shoulder 28.
    The heating element 20 comprises a tubular metallic sheath 38, of substantially cylindrical shape, preferably cylindrical of revolution. The tubular metal sheath 38 is for example made of stainless steel, in particular stainless steel 316. By way of example, the sheath 38 has an external diameter of approximately 2 mm and an axial length of approximately 40 mm. The sheath 38 extends here along the first longitudinal axis X.
    The tubular metal sheath 38 has a proximal part 42 and a distal part 44, adjacent along the longitudinal axis X. The proximal part 42 is disposed inside the gripping element 18 and the distal part 44 forms a axial projection relative to the distal end 24 of the gripping member 18.
    A proximal end 46 of the tubular sheath 38 is open. A distal end 48 of said sheath 38 is preferably closed. The sheath 38 is in particular manufactured by a deep drawing process or produced from an open tube provided with a shutter at its distal end 48. Alternatively, the distal end is open.
    In this example, the proximal part 42 of the sheath 38 is inserted into the distal part 22 of the handle 18. The tubular cavity 26 of the distal part 22 extends the tube formed by the sheath 38, along the longitudinal axis X.
    The heating element 20 also comprises a resistive assembly 50, visible in FIG. 1.
    The resistive assembly 50 comprises a rod 52, capable of being inserted into the tubular metal sheath 38. Preferably, the rod 52 is made of an electrically insulating material such as a plastic. As a variant, the resistive assembly 50 is devoid of support 52.
    The resistive assembly 50 further comprises a resistive wire 54 wound around the rod 52. The resistive wire 54 is for example made of Nichrome with a diameter of 0.14 mm.
    Preferably, the resistive wire 54 is wound over a whole length of the rod 52. Advantageously, the resistive wire 54 is wound in the form of a double helix around the rod 52, so that two ends 56 of said wire extend in the gripping element 18 from a proximal end 58 of the rod 52.
    The rod 52 is inserted into the tubular metal sheath 38, so that the resistive wire 54 is in thermal contact with an internal wall of said sheath. Preferably, the wire 54 is bonded to the internal wall of the sheath 38, using an adhesive allowing good thermal conduction between said wire 54 and the sheath 38.
    The resistive assembly 50 further comprises a temperature sensor 60, disposed on the rod 52 and in thermal contact with the internal wall of the sheath. The sensor 60 is for example a CTN thermistor.
    The heating element 20 further comprises a source of electrical energy (not shown), housed in the proximal part of the gripping element 18. The ends 56 of the resistive wire 54 extend into the tubular cavity 26 of the gripping element 18 and are connected to said source of electrical energy, which thus supplies the wire 54. Advantageously, the energy source is connected to a switch disposed on the surface of the proximal part of the gripping element 18.
    Preferably, the heating element 20 further comprises an electronic regulation device (not shown), housed in the proximal part of the gripping element 18. Such an electronic device comprises for example an electronic card to which the sensor is connected temperature 60. Such an electronic device makes it possible in particular to limit the temperature measured by the sensor 60 to a determined range. Such a range is for example defined between 50 ° C. and 70 ° C. A user's risk of burns is thus limited.
    The applicator member 12 is illustrated in more detail in Figures 3 to 7.
    Advantageously, the applicator member 12 is formed in one piece. It is made of thermoplastic or metallic material. For example, the applicator member 12 is made of one or more of the materials chosen from the following list: a silicone, latex, a reinforced sliding material, butyl, EPDM, a nitrile, a thermoplastic elastomer , a polyester, polyamide, polyethylene or vinyl elastomer, a polyolefin such as PE or PP, PVC, EVA, PS, SEBS, SIS, PET, POM, PU, SAM, PA, PMMA. The applicator member 11 is for example made of materials known under the brands Teflon®, Hytrel®, Cariflex®, Alixine®, Santoprene®, Pebax®, Pollobas®.
    The applicator member 12 comprises a cylindrical sleeve 135 applied to the heating element 20 and a plurality of separation / combing elements 137 extending laterally projecting from the sleeve 135. The sleeve 135 defines a plurality of openings through 139 in said sleeve 135, intended to bring the cosmetic product into contact with the heating element 20.
    As visible in FIGS. 1 and 2, the sleeve 135 defines an internal cavity 143 of elongated shape. The internal cavity 143 has an open proximal end 145 (Figure 7) and a closed distal end 147 (Figure 6). At the proximal end 145, the internal cavity 143 has a shape complementary to the distal end 24 of the gripping member 18.
    The sleeve 135 has a proximal mounting part 150A on the distal part 22 of the gripping element 18, a rounded distal part 150B and an intermediate part 150C situated between the proximal part 150A and the distal part 150B.
    The proximal mounting part 150A is here tubular around the longitudinal axis X. It advantageously comprises an element for fixing 149 to the assembly mechanism carried by the distal part 22 of the gripping element 18. In this example, the mechanism assembly comprises an annular projection (not shown) and the fixing element 149 is formed by a circumferential groove receiving the annular projection.
    The through openings 139 are distributed circumferentially around the longitudinal axis X. Thus, for any axial plane passing through the longitudinal axis X, the applicator member 12 defines at least one first through opening 139 on a first side of the axial plane, and defines at least one second through opening 139 on a second side of the axial plane.
    The through openings 139 constitute cosmetic product traps in which the keratin fibers are caused to immerse during application. The keratin fibers are loaded with cosmetic product heated to the optimum temperature for use by the heating element 20 by plunging into the through openings as close as possible thereto.
    As shown in Figures 3 to 5, the through openings 139 are aligned in a plurality of rows 149 distributed circumferentially around the longitudinal axis X. Each row 149 extends along a generatrix of the sleeve 135.
    In the embodiment shown in Figures 3 to 5, the through openings 139 are aligned in a number of rows 149 between four and twelve, for example six. The number of through openings 139 per row 149 is between five and fifteen, for example three rows 149 have nine through openings 139 and three rows 149 have eight through openings 139.
    The through openings 139 are for example spaced at a constant pitch p along a row 149. The pitch p is advantageously identical from one row 149 to another. For example, the through openings 139 are spaced apart by a pitch of between 0.8 mm and 1.2 mm, typically 1 mm.
    In this example, the through openings 139 in each row 149 are offset longitudinally from the through openings 139 in the adjacent rows 149. The through openings 139 are thus staggered from one row 149 to another.
    This particular arrangement avoids that during the application of the cosmetic product, a keratin fiber does not pass directly from one through opening 139 to another, in particular during the rotation of the application device 10 relative to the keratin fibers.
    Advantageously, the through openings 139 have a cross section whose larger dimension extends substantially in a direction perpendicular to the longitudinal axis X.
    In the example of Figure 3, the through openings 139 have a diamond-shaped cross section.
    Thus, the diamond shape optimizes the number and size of the through openings 139 on the application device member 12. This increases the loading of the application member 12 in cosmetic product.
    Alternatively, the cross section of the through openings 139 has any polygonal shape such as a square or rectangle shape. In another variant, the cross section of the through openings 139 has a circular or elliptical shape or comprises at least one circular, elliptical or curved portion.
    In the example illustrated by Figures 3 to 5, the diamond-shaped section of the through openings 139 has a larger diagonal which extends substantially in the direction perpendicular to the longitudinal axis X.
    This characteristic allows the keratin fibers to plunge into the through openings 139 while being as close as possible to the heating element 20 and thus to be loaded with cosmetic product heated to optimal temperature.
    Advantageously, the through openings 139 have a first cylindrical projection p! on an internal surface of the sleeve 135 visible in FIG. 5, the area of which is less than the area of a second cylindrical projection p 2 on an external surface of the sleeve 135 visible in FIG. 4.
    The edges 151 of the through openings 139 are thus chamfered so that the through openings 139 have a flared shape from an internal surface to an external surface of the sleeve 135.
    Advantageously also, the first cylindrical projection pi and the second cylindrical projection p 2 respectively have a dimension ai and a dimension a 2 along the longitudinal axis X and, a dimension bi and a dimension b 2 in a direction perpendicular to the longitudinal axis X, so that the ratio a 2 / ai is greater than the ratio b ^ bp As can be seen in Figure 2, the chamfer of the long diagonal of the rhombus is wider than that of the small diagonal of the rhombus. Thus, the through opening 139 is more flared between the internal surface and the external surface of the sleeve 135 in the direction perpendicular to the longitudinal axis X.
    The chamfering of the edges 151 of the through opening 139 promotes the loading of the keratin fibers with cosmetic product as close as possible to the heating element 20.
    The separation / combing elements 137 are distributed circumferentially around the longitudinal axis X. Thus, for any axial plane passing through the longitudinal axis X, the applicator member 12 comprises at least a first separation / combing element 137 on a first side of the axial plane, and comprises at least one second separation / combing element 137 on a second side of the axial plane.
    The separation / combing elements 137 are aligned in a second plurality of rows 153, 155 distributed circumferentially around the longitudinal axis X. Each row 153, 155 of separation / combing elements 137 extends along a generatrix of the sleeve 135 The application device 10 according to the invention comprises a number of rows 153, 155 between eight and eighteen, for example twelve.
    The separation / combing elements 137 are for example formed by studs projecting towards the outside of the sleeve 135. Each spike here has a shape that tapers towards a free end.
    The separation / combing elements 137 have for example a length of between 1 mm and 5 mm, typically 3 mm.
    The application member 12 comprises at least a first plurality of rows 153 of separation / combing elements 137 along which the separation / combing elements 137 are spaced from each other by a first constant distance d v The member d application 12 further comprises a second plurality of rows 155 of separation / combing elements 137 along which the separation / combing elements 137 are spaced from each other by a second constant distance d 2 . According to the invention, the distance d 2 is greater than di.
    Thus, the rows 153 have a higher density of separation / combing elements 137 than the rows 155.
    In the embodiment presented, the application device 10 comprises between four and ten rows 153, for example, six rows 153 for which the separation / combing elements 137 are spaced apart by a distance di of between 0.2 mm and 2 mm, for example 0.5 mm.
    The application device 10 comprises between four and ten rows 155, for example, six rows 155 for which the separation / combing elements 137 are spaced by a distance d 2 of between 0.2 mm and 2 mm, for example 0 , 5 mm.
    As shown in FIGS. 3 and 4, the applicator member 12 alternately comprises a row 153 of separation / combing elements 137 of the first plurality of rows 153 and a row 155 of separation / combing elements 137 of the second plurality of rows 155. Preferably, the separation / combing elements 137 of a row 155 are staggered relative to the separation / combing elements 137 of the adjacent row 153.
    Advantageously, the rows 155 of separation / combing elements 137 and the rows 149 of through openings 139 extend along the same generatrix of the sleeve 135, so as to have, along said generatrix, an alternation between separating elements / combing 137 and through openings 139.
    As shown in Figure 3, each combing / separating element 137 of a row 155 is arranged axially opposite a through opening 139 of an adjacent row 149. Advantageously, the combing / separating element 137 is located axially in the middle of the through opening 139.
    At least two successive separation / combing elements 137 in a row 153 are located axially opposite a through opening 139, on either side of the middle of the through opening 139, defining a gap 156 for guiding towards opening 139. Advantageously, a combing / separating element 137 of a row 155 is placed opposite the gap 156.
    Thus, the combing / separating elements 137 are distributed over the sleeve 135 along two helices, of opposite pitch, interlacing the through openings 139. The separation / combing elements are uniformly spaced along one helix.
    This particular implantation of the separation / combing elements 137 forms successive baffles which the keratin fibers bypass during application. The keratin fibers thus bend to pass between the separation / combing elements 137. The keratin fibers are also braked by the separation / combing elements 137 so that they become loaded with cosmetic product by plunging into the through openings 139 containing the product cosmetic at the optimal temperature.
    The operation of a packaging and application unit implementing an application device 10 according to the invention will now be described with reference to Figures 3 and 7.
    In a first step, the user enters an application device 10 according to the invention, as described above. More specifically, the user grasps the gripping member 18 of the application device 10 attached to the reservoir 11 with the application member 12 soaking in the cosmetic product. It activates the switch on the surface of the gripping member 18. The electrical energy source then supplies the heating element 20, under the control of the electronic regulation device, to heat the heating element 20 to a temperature between 50 ° C and 70 ° C.
    The user then immerses the applicator member 12 in the container 11 of cosmetic product. The cosmetic product extending in the through openings 139 of the applicator member 12 is then heated in contact with the heating element 20 to the desired temperature, between 50 ° C and 70 ° C
    Then, the user extracts the application device 10 from the reservoir 11 and prints a rotation and / or translation movement of the application device at the level of the keratin fibers.
    As a variant, provision may be made for the heating element 20 to be powered by the electrical energy source only once the application device 10 has been extracted from the reservoir 11, with the cosmetic product loaded on the application member 10 , in particular in the through openings 139, in particular so as not to subject the cosmetic product contained in the reservoir 11 to a superfluous heating / cooling cycle.
    As illustrated in FIGS. 3 and 8, the keratin fiber 157 is guided by two separation / combing elements 137 of a row 153 towards the long diagonal of a through opening 139 to load with cosmetic product at optimal temperature.
    The keratin fiber 157 is then combed and stretched in a direction substantially perpendicular to the longitudinal axis X by passing between two separation / combing elements 137 of an adjacent row 153 and bypassing a separation / combing element 137 of a row 155.
    The application process can be repeated successively by the user.
    Between each repetition or after several repetitions of the process, the user can recharge the application device 10 in cosmetic product by immersing it in the product tank.
    Thus, the application device 10 according to the invention has the advantage of comprising an application member 12 which is simple to use. Indeed, the cosmetic product can be applied without having to seek a particular angular position of the applicator member 12 relative to the keratin fibers. The applicator member 12 is also more efficient in terms of recharging cosmetic product. The autonomy of the application device 10 is thus increased and the user does not need to frequently recharge the application device 10 with a cosmetic product.
    In addition, in order to apply the cosmetic product at a temperature as close as possible to the temperature of the heating element 20, the application member 12 of the application device 10 according to the invention has through openings 139 distributed over the entire periphery of the applicator member 12. The large number and the particular shape of the through openings 139 allow the keratin fibers to plunge as deeply as possible, into the through opening 139, as close as possible to the element heating in the direction perpendicular to the longitudinal axis X to load the cosmetic product as efficiently as possible on the fibers.
    The implantation of the separation / combing elements 137 relative to the through openings 139 allows separation, combing and optimal stretching of the keratin fibers.
