Definitions

  • the present invention relates to an applicator for applying a cosmetic, makeup or care product to keratin materials, in particular keratin fibers, for example the eyelashes and/or eyebrows, and also to a packaging and application device comprising such an applicator.
  • the invention relates more particularly to an applicator comprising a wand that has a distal end extending along a longitudinal axis and a molded applicator member fixed to the end of the wand, the applicator member comprising a core and teeth extending from the core.
  • the subject of the invention is in particular an applicator in which the core does not extend entirely in the axis of the wand.
  • Patent application FR 2 939 619 relates to an applicator having two different application faces.
  • the applicator member comprises rows of large teeth and rows of small teeth, the rows of large teeth and of small teeth differing by way of the spacing between the teeth, the number of teeth in a row or the thickness of a tooth measured perpendicularly to its direction of elongation.
  • the invention aims to further improve applicators intended for applying makeup to the eyelashes and eyebrows, in particular to make it possible to provide at least two different types of makeup, with a single applicator and in a simple and reliable manner.
  • the invention aims to meet all or part of these needs.
  • an applicator for applying a cosmetic, makeup or care product to the eyelashes or eyebrows comprising a wand that has a distal end extending along a longitudinal axis X and a molded applicator member located at the distal end of the wand, the applicator member comprising:
  • teeth extending from the core the teeth having free ends that define an envelope surface E of the applicator member
  • the envelope surface E having a cross section with a flattened shape along a flattening plane P at at least one point on its length, better still along at least half of its length, even better still along its entire length, and
  • the longitudinal axis Y of the core extending in a plane Q perpendicular to the flattening plane P of the cross section of the envelope surface and being inclined in this plane Q at a non-zero angle a with respect to the longitudinal axis X of the distal end of the wand.
  • the inclination of the applicator member with respect to the wand makes it possible to define two main application faces, on on the side toward which the core is inclined and the other on the opposite side. These two main application faces can make it possible to obtain different makeup results, in particular by virtue of their different orientations with respect to the longitudinal axis X of the distal end of the wand.
  • more makeup can be applied when the user brings the face located on the side of the inclination of the core into contact with the eyelashes.
  • the makeup can be applied with a more combing and separating effect when the user brings the face located on the side opposite the inclination of the core into contact with the eyelashes.
  • the user can use only one of these faces, or a plurality thereof, during successive phases of the same application of makeup.
  • the user can use two different faces in succession or alternately, and can succeed in depositing more product on the eyelashes without having to reload the applicator member with product, for example without having to dip it into a container again during the application of the makeup.
  • the applicator according to the invention thus makes it possible to deposit large quantities of product on the eyelashes or eyebrows while ensuring that the latter are combed and separated in a satisfactory manner. Furthermore, the makeup result obtained can be reproducible if necessary.
  • the applicator according to the invention makes it easier to obtain a satisfactory makeup result, even when the user is inexperienced. Inclination

  • the core may be approximately rectilinear.
  • the angle at one point of the core with the longitudinal axis of the end of the wand is given by the tangent to the longitudinal axis of the core at this point.

  • the applicator may have large teeth and small teeth in the same cross section.
  • the difference between the length of the large teeth and the length of the small teeth may be greater than 0.2 mm.
