  • the applicator element 22 is here fixed at the level of the second end 18b of the rod 18 by means of a flexible, deformable core 34 elastically to allow the bending of the applicator element 22 relative to the rod 18. More specifically, here, the applicator element 22 is molded onto the core 34.
  • this core 34 is made in one piece with the rod 18.
  • the core 34 and the rod 18 form a single piece.
  • the diameter d 18 of the rod 18 is chosen greater than the diameter d 34 of the core 34 so that the core 34 is flexible with respect to the rod 18, which is rigid.

  • the diameter d 34 of the flexible core 34 is for example greater than 0.3 mm, preferably greater than 0.4 mm.
  • This diameter d 34 can also or alternatively be less than 2.5 mm, preferably less than 1.5 mm, more preferably less than 0.7 mm, more preferably less than or equal to 0.6 mm.
  • the diameter d 34 of the core 34 is equal to 0.5 mm.

  • the length L over which the core 34 extends freely is at least 2 mm, or even at least 3 mm, preferably at least 5 mm.
  • the core 34 is shaped to allow maximum bending of the applicator element 22 relative to the rod 18, by elastic deformation of the core 34, such that a maximum angle ⁇ of bending between the longitudinal direction X 1 of the applicator element at rest and the longitudinal direction X 2 of the applicator element 22 flexed, measured in a longitudinal plane of the applicator device 16 including the longitudinal direction X 1 of the stem 18 and the longitudinal direction X 2 of the applicator element 22, is at least 1°, or even of at least 2°, or even of at least 5°, or even of at least 10°.
  • the applicator element 22 in the position at rest, the applicator element 22 is subjected solely to its weight and to the reaction of the core 34. In the bent position, an additional external force is applied to the applicator element, for example by the material keratin on which the cosmetic product is applied.
  • the core 34 allows a relative movement of the applicator element 22 with respect to the rod 18. It should be noted here that the core 34 being more flexible than the rigid rod 18, it is the core 34 which deforms and not the stem 18, in the event of application of a force to the applicator element 22. This deformation makes it possible to compensate for excessive pressure on the applicator element 22, pressure which could be painful without this deformation. This deformation thus induces greater comfort of application. In addition, this deformation also makes it possible to use an applicator element 22 whose spikes are more rigid, the rigidity of the spikes being particularly advantageous for combing the eyelashes or the eyebrows on which the cosmetic product is applied.
  • the maximum bending between the applicator element 22 and the stem 18, obtained by elastic deformation of the core 34, is limited.
  • the maximum bending angle ⁇ of the applicator element 22, obtained by elastic deformation of the core 34, is at most 30°, preferably at most 20°. Too great a maximum angle of flexion ⁇ can in fact impair the precision of the make-up. Too great a maximum angle of flexion ⁇ can also induce a pressure necessary for the application, which is very high, making the makeup operation tricky.

  • the core 34 is not made in one piece with the rod 18, but with the applicator element 22.

  • the base 32 may in particular be of round section, with a diameter d 32 less than the diameter d 30 of the smallest base of the first zone 30a of the application portion 30.
  • the cylindrical surface of the base 32 is recessed by relation to the surface of the application portion 30, so that the base 32 cannot be in contact with the keratin material on which the cosmetic product is to be applied. This prevents the base 32 from being used to apply the cosmetic product, which would harm the precision of the application of the cosmetic product.
  • the base 32 is thus separate from the application portion 30 of the applicator element 22.
  • the diameter d 32 of the base 32 is for example at least twice smaller than the diameter d 30 of the smallest base of the first zone 30a.

  • the bristled portion 86 thus makes it possible to define the maximum angle of flexion.
  • this bristle portion 86 makes it possible to ensure control of the bending of the core, by the damping induced by the contact of the bristles of the bristle portion on the side wall 60 of the housing 52.
  • the quality, in particular the stiffness, of the tufts of bristles 82 of the application portion 30 can be different from the quality of the tufts of bristles of the hairy zone 86.
  • the stiffness of the tufts of bristles 82 can however be chosen also relatively large, this allowing for example to comb the eyelashes during the application of a mascara, the comfort of application then being ensured by the possible bending of the applicator element 22.
  • This last embodiment is of particularly simple design, the twisted wire necessary for fixing the tufts of bristles being implemented as a core allowing the bending of the applicator element 22 with respect to the rod 18. No other part intermediary is not necessary.
  • the core 34 consists of a twisted metal wire 84, in which the bristles are held.
  • the core strands 34 can be twisted left or right.
  • Core 34 can also be a double core, formed by two elementary cores twisted together. Each elementary core can comprise two strands twisted together and enclosing hairs.
  • the two elementary cores can each be constituted by a branch of a single twisted core folded in the shape of a U, the two branches being twisted together.
  • bristles and in particular bristles having a circular or other than circular cross-section. It is possible in particular to use a mixture of bristles of different kinds or a mixture of bristles of different lengths, of the same kind or not.
  • the bristles can have a diameter of between 6.5 hundredths of a millimeter and 40 hundredths of a millimeter.
  • the cross-section of the bristles can in particular be round, oval, polygonal, circular with a flattened part, star-shaped, cross-shaped, U-shaped, H-shaped, T-shaped, V-shaped.
  • the bristles which are retained between the twisted strands of the core may have, before being placed between the strands of the core, a rectilinear shape or not, for example a wavy shape.
  • the bristles can be subjected to a treatment making it possible to form balls or forks at their ends.
  • the bristles may be flocked.
  • the bristles can be made by extruding a plastic material comprising a filler of particles, for example particles of a moisture-absorbing material, in order to impart a microrelief to the surface of the bristles or to give them magnetic or other properties. .
  • the bristles can be natural or synthetic, for example be made of a material chosen from: PE, PA, in particular PA6, PA6/6, PA6/10 or PA6/12, HYTREL ® , PEBAS ® , silicone, PU, this list n not being limiting.
  • FIG. 9 And 10 illustrate a variant 90 of the embodiment of the figure 8 .
  • the longitudinal direction X 1 of the applicator element 22 at rest and the longitudinal direction X 0 of the rod 18 are not coincident, nor parallel.
  • the longitudinal direction X 1 of the applicator element 22 forms, even at rest, a non-flat angle with the longitudinal direction X 0 of the rod 18.
  • This can allow a particular use of the applicator element 22, in particular by favoring a particular face of the application portion rather than another.
  • the core 34 is bent.
  • the core 34 has two substantially rectilinear sections extending in two directions forming a non-flat angle.
  • core 34 may be curved over at least a portion of its length.
  • the applicator element 22 can bend in the event of use and the longitudinal direction X 2 of the applicator element 22 flexed forms an angle with the longitudinal direction X 1 of the applicator element 22, at rest, as described previously .
  • the deflection can be carried out locally at the level of the elbow formed at rest by the core 34 and/or over all or part of the core extending between the hole 58 and the elbow and/or over all or part of the core extending between the elbow and the free end of the web 34.
  • the longitudinal direction X 2 of the bent applicator element 22 may optionally be aligned with the longitudinal direction X 0 of the stem 18 or, as illustrated in the figure 10 , form an angle with this longitudinal direction X 0 of the rod 18 greater than the angle formed by the longitudinal direction X 1 of the applicator element 22 at rest, with respect to this longitudinal direction X 0 of the rod 18.
  • the figure 11 And 12 illustrate a variant 100 of the embodiment of the figure 8 .
  • the core 34 is here devoid of bristled portion 86, received in the housing 52.
  • all the bristles enclosed in the core 34 are here part of the application portion 30 of the applicator element 22.
  • the maximum flexion of the applicator element 22 with respect to its position at rest can be defined by the core 34 coming into abutment on the end of the side wall 60 of the housing 52.
  • example 110 of figures 13 and 14 differs from example 70 of figures 6 and 7 essentially in that the housing 52 at the end of the rod 18 is tapered.
  • a frustoconical shape makes it easier to mount the applicator element 30.
  • such a frustoconical housing 52 makes it possible to guide the core 34 towards the hole 58 in the stem 18.
  • the diameter of the housing 52 measured at its end into which the hole 58 opens, is substantially equal to the diameter of the hole 58.
  • the length L of the tapered housing 52, measured along the longitudinal direction X 0 of the rod 18, corresponds to the length of the core 34 extending freely. This length L can be within the value ranges indicated previously.
  • the length of the tapered housing 52 can be 10 mm.
  • the diameter d 52 of the housing 52 which corresponds, in the case of a housing 52 tapered to the maximum diameter of housing 52, measured at the end of rod 18, may be between 1 and 3 mm, preferably be equal to 2.5 mm.
  • the frustoconical shape of the housing 52 can be implemented in all the previous examples where the rod 18 has a housing 52, independently of the nature of the applicator element 30 and/or of the core 34.
  • the diameter d 18 of the rod 18 is for example, in example 110 figures 13 and 14 , between 3 mm and 4 mm. This value of the diameter d 18 of the rod 18 can also be applied to the other examples described above.
  • the applicator element can be of any suitable type and/or of any geometry suitable for the application of cosmetic product on keratin materials, in particular keratin fibers such as the eyelashes or the eyebrows.
  • the applicator can be a flocked applicator.
  • the rod 18 is substantially cylindrical.
  • the rod 18 is not flared at its second end 18b where the housing 52 opens out.
  • Such a flare does not appear necessary, which can make the applicator device 50 more difficult to introduce into its container 14.
  • such a flare may also be provided in certain embodiments that are not illustrated.
  • the principle of bending of the core 34 is applicable to any section of this core 34, oval, polygonal or other.
  • the shape of the section of the core can make it possible to favor bending planes of the core with respect to others, which can contribute to making the application of the cosmetic product more precise.
  • the housing 52 is, in the examples described, tubular, of substantially circular cross-section.
  • the cross section of the housing 52 can take any other shape, in particular a shape of ellipse, polygon, in particular square or diamond.
  • the invention can also be implemented for applicators other than mascara applicators, for example for eye shadow applicators, blushers, eyebrow applicators, product applicators on the lips.
