  • Applicator heads designed to be heated.
  • Application W099/22782 teaches curving the eyelashes with the aid of a ceramic heating element.
  • Application FR 2 890 543 describes a double turn of a heating resistance wire intended to curl the eyelashes.
  • Application EP 0 848 920 discloses a device for curling the eyelashes, comprising a curved part adapted to the morphology of the eye and the eyelashes which is partially in contact with the eyelashes during use.
  • the temperature of the heating element is maintained between 80°C and 120°C.
  • Application EP 1 543 741 describes a heating member located between two rows of projecting elements.
  • Applicators for making up the eyelashes and eyebrows said applicators being designed to heat and liquefy the composition to be applied.
  • Application FR 2 899 445 describes an applicator that uses electrostatic properties of the applicator element.
  • the known devices tend to differentiate between the combing and curling of the eyelashes. There exists a need to allow combing and curling of the eyelashes in a single hand movement and to benefit from a device for making up the eyelashes that is capable of producing a satisfactory curling effect.
  • the subject of the invention is an applicator for applying a product to keratin fibers, in particular the eyelashes and eyebrows, comprising an applicator member having:
  • a heating element comprising a heating resistance wire comprising two adjacent portions which are preferably approximately parallel to one another and define a space between one another, several teeth connected to the core being disposed in this space.
  • the invention makes it possible, in a single hand movement, to comb the eyelashes with the teeth and to subject the eyelashes to the heat released by the heating element, in particular by way of contact between the eyelashes and the heating element.
  • the user can choose to heat the eyelashes with the heating element in order to curl them, while loading the eyelashes with product and combing them with the teeth.
  • the resistance wire is heating when an electric current passes through it and when it releases heat by the Joule effect.
  • the surface temperature of the heating element during use is, for example, between 60°C and 90°C, preferably approximately equal to 70°C. This temperature allows effective curling of the eyelashes while ensuring comfort during application.
  • the maximum temperature of the heating element is for example reached after 5 s to 60 s of heating.
  • the applicator may comprise an electric circuit designed to control the temperature of the heating element, or to regulate it.
  • the applicator member may be called either “comb” or “brush” in the case of the present invention, and the “teeth” may also be called “bristles”.
  • the free ends of the teeth may define an envelope surface which extends along a longitudinal axis that may coincide with the longitudinal axis of the core and possibly also coincide with a longitudinal axis of the heating element.
  • the envelope surface may have a greatest transverse dimension, for example diameter, that is substantially constant along at least a part of the length of the applicator member.
  • the envelope surface may also have a section which varies on moving along its longitudinal axis.
  • the section may pass through an extreme at a distance from the axial ends of the envelope surface, this extreme being for example a maximum or a minimum.
  • the envelope surface may have the shape of a peanut or a rugby ball, be frustoconical or biconical, or have any other shape that is known for a mascara brush.

  • the longitudinal row of teeth may be parallel to the longitudinal axis of the core.
  • transverse row denotes a succession of teeth located in a plane transverse to the longitudinal axis of the core and following one another around the core.
  • longitudinal axis of the core should be understood as meaning the line which connects all of the centers of mass of the cross sections of the core.
  • the longitudinal axis may in certain cases be a central axis, or even an axis of symmetry for the core, in particular when the core has a cross section whose contour has the general shape of a regular polygon or is circular.

  • the teeth may have a thickness of between 0.05 and 2 mm, better still between 0.2 and 0.5 mm. When the thickness is less than 0.5 mm, the teeth are relatively thin and may also be relatively flexible when the material of which they are made is a flexible material.
  • the thickness of the teeth may be chosen for example depending on the type of makeup result to be achieved and/or on the nature of the eyelashes to be treated and/or on the rheology of the product.
  • teeth length or “tooth height” denotes the distance measured in the direction of elongation of the tooth between the free end of the tooth and its base, by way of which it is connected to the core.
  • the length of a tooth is thus measured from the core of the applicator member.
  • the teeth may have a length of between about 0.5 and 15 mm, and preferably between 2 and 5 mm.

  • the heating wire 70 may comprise an electrically conductive core 72, made for example of nichrome, containing for example 60% by mass of nickel and 16% by mass of chromium, and an electrically insulating outer coating 73, for example enameling.
  • the heating wire has no electrically insulating outer coating.
  • the diameter of the heating wire 70 is for example between 0.05 mm and 3 mm, being in the region of for example 0.7 mm.
