Definitions

  • the present invention relates to an applicator for applying a product to the eyebrows, a packaging and application device comprising such an applicator, and a method for cosmetic treatment of the eyebrows.
  • the U.S. Pat. No. 8,051,860 thus discloses a device for applying a cosmetic coloring composition in the region of the eyebrows, comprising an endpiece impregnated with said composition. Such a device is used in the manner of a pad.
  • EP 1 649 777 A2 discloses a device for packaging a product and for applying it to the eyelashes or eyebrows, in particular mascara, said device comprising a comb with a relatively small number of teeth. Such a device is suitable very particularly for making up the eyelashes at the corner of the eye.
  • WO 2010/007588 A2 discloses an applicator comprising teeth that extend in different directions and that are connected to a body of generally cylindrical shape along the longitudinal axis of the application member. Although the application of product to the eyelashes is envisioned, such an applicator is nevertheless more particularly suitable for applying the product to the eyelashes.
  • the invention aims to meet this need and it achieves this by virtue of an applicator comprising
  • length designates the longitudinal direction of the application member
  • width designates the perpendicular direction
  • the user has available an applicator which is very particularly suitable for precisely making up the eyebrow fringe.
  • the user can use the applicator to color the eyebrows, without staining the skin.
  • this applicator is used with a container which is provided with a wiping element, as explained in detail below.
  • the stem of the applicator can be made relatively fine and does not greatly obstruct the view of the eyebrow fringe when the user is applying makeup.
  • a narrower shape at the end of the application member is compatible with an implantation of the spikes that is suitable for precise and effective making up of the fringe of the eyebrows, and the distal end of the application member can thus be used to manage the eyebrows, likewise the back of the application member, opposite the application face, which can be made without application element.
  • the applicator can comprise a succession of a maximum of four or five spikes, in the direction of the length of the application face and/or of three to five spikes in the direction of the width of the application face.
  • the total number of spikes carried by the application member is thus relatively small and preferably between 8 and 15.
  • a relatively low number of spikes is advantageous in that it facilitates the management of the eyebrows and the engagement of the hairs between the spikes.
  • the application member is preferably used with a cosmetic composition that is more fluid than a mascara conventionally used for making up the eyelashes of the eyelid.
  • All the spikes are preferably implanted on the portion of decreasing width of the application face.
  • the back of the application member, opposite the application face carrying the spikes is smooth. This back can be used to manage the hairs while applying makeup, as indicated above.
  • the spikes can be arranged in rows, preferably at a constant spacing within one and the same row and, better still, a constant spacing between the spikes of all the rows.
  • the number of spikes per row decreases in the direction away from a longitudinal median plane of the application member.
  • the application member comprises a central row which comprises the greatest number of spikes, and the other rows comprise fewer spikes than this central row.
  • the latter is preferably situated along a median plane of symmetry of the application member.
  • the spikes can be arranged in substantially concentric arcs of implantation around a point situated to the front of the application member.
  • the spikes can be arranged in rows that are aligned in the direction of the length of the application face.
  • the spikes can be arranged in rows parallel to the longitudinal axis of the application member. These rows may or may not be offset with respect to one another in the longitudinal direction of the application member, the offset between two adjacent rows being, for example, between 1 ⁇ 4 and 3 ⁇ 4 of the mean spacing between the spikes within one and the same row, said spacing being measured at the base of the spikes.
  • the spikes are preferably of a longitudinal axis parallel to a same direction, which is preferably not parallel and not perpendicular to a longitudinal axis of the application member.
  • the longitudinal axis of the spikes preferably forms, with the longitudinal axis of the application member, an angle that is not a right angle, such that the spikes are oriented obliquely with respect to the longitudinal axis of the stem, preferably by an angle ⁇ of between 30 and 80°.
  • the spikes are thus preferably oriented toward the front of the applicator.
  • no spike is of a longitudinal axis parallel to the longitudinal axis of the stem.
  • no spike is of a longitudinal axis perpendicular to the longitudinal axis of the stem.
  • the longitudinal axis of the application member prefferably coincident or not to be coincident with the longitudinal axis of the stem.
  • the application face can be slightly convex toward the outside, and the envelope surface defined by the free ends of the spikes can also be convex toward the outside, for example being parallel to the application face.
  • the free ends of the spikes all belong to one and the same plane, which is preferably not parallel to the longitudinal axis of the application member.
  • the body of the application member preferably has a general shape flattened in a flattening plane, which can be oriented generally perpendicularly with respect to a median plane for the application face.
  • the greatest width of the body of the application member is preferably greater than the length of the largest of the spikes.
  • the greatest width w max of the body of the application member can be greater than the diameter d tige of the stem of the applicator in its region adjacent to the application member.
  • the axes of the spikes can be oriented substantially perpendicularly with respect to said flattening plane.
  • a flattened shape of the body of the application member is advantageous in that it tends to ovalize the wiping element to the passage of the application member and may lead to further wiping of the spikes, which reduces the quantity of product present at their end and reduces the risk of staining the skin by excessive application of product.
  • the application member may have a symmetrical shape with respect to a longitudinal median plane. At least one row of spikes can extend in this longitudinal median plane.
  • the spikes are molded in one piece with the body of the application member and are preferably made of an elastomer material so as to impart flexibility to the application member.
  • the application member can have a sufficient flexibility such that the spikes and/or the body of the application member can deform during passage through the wiping element and/or during the application of the product to the eyebrows.
  • the application member preferably comprises an endpiece which is molded integrally with the body of the application member.
  • This endpiece serves for mounting the application member in the stem, the latter having a recess for this purpose.
  • the longitudinal axis of the endpiece can form an angle which is not zero with the longitudinal axis of the body of the application member.
  • the longitudinal axis of the body of the application member is coincident with the longitudinal axis of the endpiece.
  • the spikes are not flocked, since this reduces the quantity of product retained at the end and, hence, reduces the risk of applying product to the skin.
  • the spikes can be of the same length. However, the spikes are preferably of a variable length.
  • the application member comprises a spike of greater length situated near its distal end.
  • This spike is preferably of a longitudinal axis situated in a median plane of symmetry of the application member.
  • the length of the spikes can thus increase toward the free end of the application member, preferably increasing by at least 20%, for example going from 2.4 mm to 3 mm, or in this case by 25%.
  • a longer spike, near the distal end of the application member, is advantageous in that it provides the user both with a spike that is well wiped and also with a reserve of product near this spike, said reserve being composed of the drop of product that tends to remain in the continuation of the application member after wiping, since it is not removed by the wiping element.
  • Such a spike may help the user perform precise and careful making up of the eyebrows.
  • the application face to which the spikes are connected is preferably inclined with respect to the longitudinal axis of the application member.
  • the spikes can be connected non-rectilinearly to this application face, preferably leaning slightly forward when the application member is observed in cross section in a plane parallel to its longitudinal axis, for example in cross section in a median plane when the application member comprises a central row extending along this median plane.
  • the longest spike can be connected via its base to the application face at a position set back from the free end of the application member, by a distance which is for example substantially equal to the distance separating it from the following spike within the row.
  • the application member comprises a central row of at least three spikes, preferably four spikes, of which the length increases, preferably linearly, toward the free end of the application member, and two lateral rows of at least two spikes each, preferably offset axially with respect to the central row by about half the spacing between two consecutive teeth, measured at their base, of the central row.
  • all the spikes are present on a portion of the application face whose length decreases toward the free end of the application member.
  • the spikes are connected to an inclined application face and are preferably of mutually parallel longitudinal axes, all preferably inclined toward the front.
  • a further subject of the invention is a packaging and application device, comprising an applicator according to the invention and a container containing the product to be applied.
  • This container is preferably provided with an element which serves for wiping the stem and the application member and through which the application member passes when the applicator is withdrawn from the container. It is particularly advantageous that the body of the application member is wider than the smallest internal diameter of the wiping element, since this makes it possible to wipe the spikes more vigorously, the tip thereof thus carrying less product, which fact reduces the risk of staining the skin and can allow makeup to be applied with care.
  • the applicator can comprise a grip element designed to close the container when the latter is not in use. The stem of the applicator is connected to this grip element.
  • a further subject of the invention is a method for making up the eyebrows, in which method a cosmetic product is applied, with the aid of the applicator according to the invention, to the eyebrows.
  • the product is advantageously taken from a container provided with a wiping element.
  • the product is applied with the aid of the spikes and of the application face.
  • the back of the application member can be used to move the hairs without seeking to apply product.

  • the packaging and application device 1 shown in FIG. 1 comprises an applicator 10 according to the invention and a container 20 containing a product P to be applied to the eyebrows with the aid of the applicator 10 .
  • the applicator 10 comprises a stem 11 which is connected to a grip element 12 designed to be fixed on the container 20 when the latter is not in use, so as to close the container sealingly.
  • the stem 11 carries an application member 30 according to the invention, comprising spikes 34 .
  • the stem 11 can be rectilinear and have a circular cross section.
  • the application member 30 can extend along a longitudinal axis X, which can be coincident with that of the stem 11 , as illustrated.
  • the applicator 10 can be fixed to the container 20 in various ways, for example by screwing the grip element 12 onto a neck 21 of the container 20 .
  • This neck 21 can at least partially accommodate an element 25 for wiping the stem 11 and the application member 30 , it being possible for this wiping element 25 to be of any type known per se, in particular one with a flexible lip as illustrated, for example, in FIG. 45 of the publication WO 2010/007588 A2 or in FIGS. 25 to 28 of the application FR 2 900 036.
  • the smallest diameter of the wiping element 25 can be equal to the diameter of the stem 11 , in its portion adjacent to the application member.
  • the product P can also be contained in a container designed to allow the application member 30 to be charged with product without passing through a wiping element.
  • the product can be contained in a container provided with a foam or with a wall permeable to the product, in contact with which the application member 30 can be charged with product.
  • the product is brought into contact with the application member by being removed by the latter directly from a pot containing the product or is applied to the application member 30 by withdrawal from a tube.
  • the stem 11 can have any shape; however, the stem 11 preferably has a circular cross section of which the diameter d tige is smaller than the greatest transverse dimension w max of the application member 30 . Thus, the latter deforms the wiping element 25 as it passes through.
  • the stem 11 can be hollow or solid and provided at its distal end with a recess into which an endpiece 31 of the application member 30 , visible in FIG. 2 , can be introduced.
  • This endpiece 31 can be fixed in the recess of the stem 11 by any known means, for example by stapling, crimping, adhesive bonding, screwing, snap-fastening or welding.
  • the stem 11 is produced in one piece with the application member 30 by molding using one or more materials.
  • the container 20 can have a body made of thermoplastic material or glass, of any shape, and opaque or transparent.

  • the body 32 has a circular shoulder 37 in the area of the connection to the endpiece 31 , and the diameter of this shoulder 37 at the base of the body 32 corresponds to the external diameter of the stem 11 , such that the body 32 takes up a position externally in the continuation of the stem 11 , without any appreciable discontinuity.
  • the body 32 of the application member defines an application face 33 which carries the spikes 34 .
  • the application member 30 is made in one piece by the molding of a single thermoplastic material, preferably a single elastomeric material.

  • the maximum width w max of the body 32 of the application member 30 is, for example, between 4 mm and 8 mm, being for example equal to 6 mm.
  • the thickness of the portion 38 can likewise decrease, as can be seen in FIG. 3 , in the direction of the free end 36 .

  • the body 32 of the application member 30 is wider than the internal diameter of the wiping element 25 , since this makes it possible to dilate the wiping lip as the application member 30 passes through and thus to wipe the spikes 34 more vigorously, so as to leave less product near the free end thereof.
  • the application member 30 has a transverse section flattened in a flattening plane F, which is generally perpendicular to the longitudinal axis of the spikes 34 after axial projection thereof on a plane perpendicular to the longitudinal axis of the body 32 , as can be seen in FIG. 4 .
