Definitions

  • Application WO 01/05271 discloses an applicator member comprising applicator elements 1 11 in the form of a fir tree, as illustrated in Figure 3, or in the form of a pine cone, as illustrated in Figure 2. As illustrated in Figures 2 and 3, these applicator elements have, at their periphery, a plurality of protuberances 116 which form notches 114 between one another and are joined to the body of the applicator element 111 having an envelope surface SE. The protuberances 116 end in a point. In the case of the fir-tree shape, illustrated in Figure 3, the protuberances 116 are oriented in the direction of the core 110.
  • the applicator elements extending outwardly from the core, the applicator elements each having at least two adjacent notches that are open in a direction away from the core and do not adjoin one another.
  • the notches do not adjoin one another makes it possible for the notches to be sufficiently rigid to limit the deformation of the applicator element and as a result to provide effective retention of product, and also allows a relatively large contact surface area between the eyelashes and/or eyebrows and the applicator element and as a result makes it possible to provide effective loading of the eyelashes.
  • the expression "longitudinal axis of the core” denotes the line connecting all of the centres of mass of the cross sections of the core.
  • the longitudinal axis may be a central axis, or even an axis of symmetry for the core, in particular when the core has a circular cross section or a cross section in the overall shape of a regular polygon.
  • the longitudinal axis of the core may be rectilinear or curved and may be contained in a plane, which may be a plane of symmetry for some, or even for all of the cross sections of the core.
  • the longitudinal axis of the core is rectilinear.
  • appcator elements denotes individualizable projecting elements that are used to apply the product and to separate the eyelashes and are produced in accordance with the invention.
  • notches denotes small openings, produced in an applicator element, that extend from the interior of the applicator element towards the periphery thereof.
  • the notches are through-notches, that is to say that they open towards the outside on at least two opposite sides of the applicator element.
  • the notches are preferably visible when the applicator element is viewed from the front.

  • the notches are preferably produced in the flattening plane.
  • flatened cross section should be understood as meaning that the applicator elements have, at least over a part of their height, a cross section, measured perpendicularly to their direction of elongation, which has an elongate shape in a flattening plane, that is to say is wider than it is thick.
  • the applicator elements preferably have, in front view, an envelope surface that is approximately in the form of a petal or half a petal.
  • the envelope surface may have, in front view, a width that increases over a part of its height which extends from the base of the applicator element in the direction of the free end of the latter, and then decreases over the rest of its height.
  • the contour of the envelope surface, in front view does not have any angular points. This form makes it possible in particular to have a large contact surface area with the eyelashes and/or eyebrows during the application of the product.
  • the applicator elements have, in front view, a width which increases in the direction of their distal end over their entire height.
  • the applicator elements may each be in the form, in front view, of an inverted truncated triangle.
