  An applicator for applying the product to human keratinous fibers, in order to improve its performance, more specifically to facilitate easy application of makeup and to bring various possible effects to the user, Further improvements are needed to enable effective retention and to provide an ergonomic applicator.

The present invention seeks to fulfill this object and its subject matter, according to one of the aspects of the present invention, a cosmetic, make-up or care product comprising human keratin fibers, in particular eyelashes and / or Or an applicator for applying to the eyelashes, comprising a handle and an applicator member at its distal end having a core extending along the longitudinal axis,
The handle has a linear portion extending along a linear longitudinal axis and a curved portion extending along a curvilinear longitudinal axis,
The distance between the longitudinal axis of the straight part of the handle and the longitudinal axis of the curved part of the handle, measured perpendicular to the longitudinal axis of said straight part, curves in the direction of the distal end of the handle Increase along at least a portion of the length of the
The distance between the longitudinal axis of the core and the longitudinal axis of the straight portion of the handle, measured perpendicular to the longitudinal axis of said straight portion, is the distance of the applicator member from the distal end of the handle It is an applicator that decreases by moving away at least partially.

  The handle is thus advantageously curved in a specific bending direction relative to said longitudinal axis of the straight section distally, the applicator member extending in a direction opposite to this bending direction .

  Thus, the handle can form an elbow-like bend at the point where it is attached to the applicator member. This elbow-like flex creates a gap between the handle and the applicator member, resulting in an ergonomic shape and advantageous geometry for the applicator. Thus, applying a product using this applicator is easy and intuitive.

  According to the present invention, the user can hold the applicator variously depending on the area to which the product is applied, so that the user can easily achieve the makeup effect. The user can in particular reach eyelashes located at the outer and inner ends of the eye without being disturbed by the handle touching the user's cheeks, as in some known applicators.

  The applicator according to the invention furthermore enables a very different make-up application angle compared to known applicators.

  Finally, loading the product onto the applicator can also help to make up the short eyelashes at the end of the eye, as the core at the proximal and distal ends of the applicator member Because the application element supported by can be rubbed in more than that located midway along the applicator member.

  The expression "longitudinal axis of the element" denotes a line connecting all the centroids of the cross sections of the element extending along said axis. The longitudinal axis may be a central axis, and may even be the axis of symmetry of the element, in particular when the element has a circular cross-section or a cross-section having the general shape of a regular polygon. The longitudinal axis may be contained in a plane, which may be a plane of symmetry for some or even all of the cross sections of the element.

  The distance between the longitudinal axis of the straight part of the handle and the longitudinal axis of the curved part of the handle advantageously reaches a maximum value at the point at which the applicator member is mounted on the handle. This maximum may be between 1.5 mm and 5.5 mm, better still between 2.65 mm and 4.5 mm.

  The distance between the longitudinal axis of the core and the longitudinal axis of the straight part of the handle is advantageously at a distance from the proximal and distal ends of the core, in particular three minutes of the length of the core At the point of the core, which is located between one-third and two-thirds of the core, and then, preferably, in the direction of the distal end of the core, in particular in the longitudinal axis of the linear part of the It increases until the maximum value of the distance between the curved part and the longitudinal axis is reached.

  The core of the applicator member advantageously extends along a longitudinal axis that is different from the longitudinal axis of the straight portion of the handle and the longitudinal axis of the curved portion of the handle.

  In a preferred embodiment, the longitudinal axis of the core of the applicator member extends, in particular, along at least a part of its length along the arc of a circle with a constant radius of curvature to form a curve. In one variation, the longitudinal axis of the core of the applicator member extends along at least a portion of its length along the arc of a circle having a variable radius of curvature.

The core advantageously extends along the longitudinal axis at an angle other than zero with the longitudinal axis of the straight portion of the handle at at least one point along its length.

  In one variation, the core of the applicator member extends along a linear longitudinal axis.

When the longitudinal axis of the core of the applicator member is curvilinear, and the absolute value of the difference between the radius of curvature R ₂ of the radius of curvature R ₁ and a core of curved portions of the handle, the radius of curvature of the curved portion of the handle The ratio | R ₁ −R ₂ | / R _{1 with} is between 0.1 and 3 and better still between 0.2 and 1.6. The radius of curvature of the curved portion of the handle and the radius of curvature of the core of the applicator member are preferably substantially the same.

  The tangent of the core of the applicator member may be parallel to the longitudinal axis of the straight portion of the handle.

  The distal end of the core may be off-center relative to the proximal end of the handle.

Core and Applicator Element The applicator member advantageously comprises an applicator element supported by the core and arranged in a plurality of longitudinal rows all around the core.

  The expression "application element" denotes an individually distinguishable projecting element which is intended to engage human keratin fibers.

  These application elements can be spikes, blades or arches.

  The number of longitudinal rows may be even. In total, there may be at least six longitudinal rows of application elements.

  The first face of the core comprises at least two longitudinal outer rows of application elements and a longitudinal central row of application elements which they surround, in particular axially offset with respect to the two outer rows. You may support it. The expression "axially offset longitudinal row" means that the application elements of the same stage in the outer array occupy the same position along the longitudinal axis of the core as the application elements of the same stage in the central array It should be understood as meaning not to do.

  The application elements in the two outer rows may be spikes having a half cone shape, and the application elements in the central row may be spikes having a pyramidal shape.

  The spacing between the application elements in the longitudinal row on the second and third faces and on the ridges between them is greater than the spacing between the application elements in the longitudinal row on the first face It may be large, in particular twice as large. The expression "spacing between application elements in a longitudinal row" means that between the two application elements of step n and step n + 1, two corresponding to each of the two application elements along the longitudinal axis of the row It should be understood to mean the measured distance between the intermediate planes.

  Within one and the same longitudinal row, the two application elements of stage n and stage n + 1, in particular the spacing between the two spikes, are between 0.25 mm and 3 mm, better still between 0.65 mm and 2.2 mm. You may

  This arrangement and shape of the application element along the face of the core of the applicator member provides the user with different makeup effects depending on the face used. The user can deposit the product on the eyelashes using the first side and use the remaining portion of the applicator member to separate and curl the eyelashes.

  The height of the application element may be constant along the longitudinal axis of the core. In one variant, the height of the application element varies, for example monotonically, along the longitudinal axis of the core. Within one longitudinal row, the height of the application element can be reduced in the direction of the distal end of the core, in particular along at least half the visible length of the applicator member.

  The application element may have a width of between 0.15 mm and 1.2 mm, better still between 0.35 mm and 0.85 mm. The expression "width of the application element" denotes the maximum transverse dimension of the application element in cross section along the longitudinal axis of the core.
