Description

The present invention relates to applicators for applying a cosmetic, make-up or care product to human keratin fibers, in particular eyelashes and / or eyebrows, in particular mascara, and packaging and application devices comprising a container containing the product to be applied and the applicator.

These applicators comprise, in a manner known per se, a rod and an applicator member at the end thereof. The rod may extend along a rectilinear longitudinal axis or not. The applicator member may comprise a core extending along a rectilinear longitudinal axis or not, and extend in alignment with the rod or form a bend therewith. These configurations provide the user with different grips and possibilities of use, to vary the effects of make-up. US Pat. No. 3,343,551 and WO 99/22782 disclose applicators having a bend between an applicator member and a rod extending along a rectilinear longitudinal axis. The application FR 2 738 466 describes an applicator comprising a curved rod and an applicator member extending along a rectilinear longitudinal axis, in the extension of the curvature of the rod, or forming a bend therewith. The applications FR 2 831 033 and JP 58 88912 disclose applicators comprising a rod extending along a longitudinal axis and a curved application member.

There is a need to further improve the applicators for the application of a product on human keratinous fibers, in order to improve their performance, and more particularly to allow an effective grip and have an ergonomic applicator, in order to promote easy makeup and offer the user various possible effects.

The invention aims to meet this objective and has the purpose, according to one of its aspects, an applicator for applying a cosmetic product, makeup or care, on human keratin fibers, including eyelashes and / or eyebrows , comprising a rod and, at the distal end thereof, an applicator member comprising a core extending along a longitudinal axis, an applicator in which the rod comprises a rectilinear portion extending along a rectilinear longitudinal axis and a curved portion extending along a curvilinear longitudinal axis, the distance between the longitudinal axis of the rectilinear portion of the rod and the longitudinal axis of the curved portion of the rod, measured perpendicularly to said axis, increasing towards the distal end of the stem, over at least a portion of the length of the curved portion, and the distance between the longitudinal axis of the core and the longitudinal axis of the rectilinear portion of the stem, measured perpen niquely to said axis, tapering away from the distal end of the rod, over at least a portion of the length of the applicator member. The stem is thus advantageously curved distally in a certain direction of curvature with respect to said longitudinal axis of the rectilinear portion, the applicator member extending in a direction opposite to this direction of curvature. The rod can thus form an elbow at its connection to the applicator member. This elbow provides a clearance between the rod and the applicator member, giving an ergonomic shape and an interesting geometry to the applicator. Its use for the application of the product is thus easy and intuitive. The invention offers the user a simple management of the makeup effect, because it can hold the applicator in different ways depending on the application area of the product. It can in particular reach the eyelashes located at the outer and inner corners of the eye, without being hindered by a contact of the stem with his cheek, as with some known applicators.

The applicator according to the invention also allows very different makeup angles compared to known applicators. Finally, the product load on the applicator can also contribute to helping the makeup of the small eyelashes at the corner of the eye, because the application elements carried by the soul at the proximal and distal ends of the organ application may be more drained than those located mid-length of the application member. By "longitudinal axis of an element" is meant the line joining the set of centroids of the cross sections of the element extending along said axis. The longitudinal axis may be a central axis or an axis of symmetry for said element, especially when the latter has a circular cross section or generally polygonal regular shape. The longitudinal axis may be contained in a plane, which may be a plane of symmetry for some or all of the cross sections of said element.

Rod and application member Preferably, the rectilinear portion of the rod extends over at least half the length thereof, especially over at least two-thirds of the length thereof. The curved portion of the rod may extend in an arc of a circle of constant radius of curvature. In a variant, the curved portion of the rod extends along an arc of a circle of variable radius of curvature. The cross section of the curved portion of the shank may shrink, at least a portion of the length thereof, toward the distal end of the shank. The distance between the longitudinal axis of the rectilinear portion of the rod and the longitudinal axis of the curved portion of the rod advantageously reaches a maximum at the point of connection of the applicator member to the rod. This maximum can be between 1.5 mm and 5.5 mm, better between 2.65 mm and 4.5 mm. The distance between the longitudinal axis of the core and the longitudinal axis of the rectilinear portion of the stem advantageously passes through a minimum at a point of the core located at a distance from the proximal and distal ends thereof, particularly between one-third and two-thirds of the length of the core, and then preferably increases towards the distal end of the core, in particular until reaching the maximum of the distance between the longitudinal axis of the straight portion of the core. rod and the longitudinal axis of the curved portion of the rod.

The core of the applicator member advantageously extends along a longitudinal axis different from the longitudinal axis of the rectilinear portion of the rod and the longitudinal axis of the curved portion of the rod. In a preferred embodiment, the longitudinal axis of the core of the applicator member is curvilinear, extending in particular over at least part of its length along an arc of a circle of constant radius of curvature. In a variant, the longitudinal axis of the core of the applicator member extends, over at least part of its length, along an arc of a circle of variable radius of curvature. The user can position the hollow portion of the applicator member facing the eye to apply the product on the eyelashes. The core advantageously extends along a longitudinal axis making at least one point of its length a non-zero angle with the longitudinal axis of the rectilinear portion of the rod. In a variant, the core of the applicator member extends along a rectilinear longitudinal axis.

In the case where the longitudinal axis of the core of the applicator member is curvilinear, the ratio 1R1-R21 / R1 of the difference in absolute value between the radius of curvature R1 of the curved portion of the rod and the R2 of the core, on the radius of curvature of the curved portion of the rod, may be between 0.1 and 3, better between 0.2 and 1.6.

The radii of curvature of the curved portion of the rod and the core of the applicator member are preferably substantially equal. A tangent to the core of the applicator member may be parallel to the longitudinal axis of the rectilinear portion of the rod. The angular offset between the longitudinal axis of the rectilinear portion of the stem and a line passing on the one hand by the distal end of the stem and on the other hand intersecting this axis at the point where the stem begins to s' curving, can be between 5 ° and 55 °, better between 10 ° and 45 °. The distal end of the core and the distal end of the shaft may be located on the same straight line parallel to the longitudinal axis of the straight portion of the shaft.

The core may extend on the same side of the longitudinal axis of the rectilinear portion of the shaft as the distal end of the shaft. The distal end of the core may be eccentric with respect to the proximal end of the shaft. Core and application elements The application member advantageously comprises application elements carried by the core and arranged all around it in a plurality of longitudinal rows. "Application element" means an individualizable projecting element intended to come into engagement with human keratin fibers.

These application elements may be pimples, blades or arches. In a preferred embodiment of the invention, the core of the applicator member has a cross section, taken perpendicular to its longitudinal axis, of generally triangular shape. In variants, the core has a cross section of another shape, in particular circular. The largest transverse dimension of the core may be between 1.6 mm and 5 mm. The core may have three faces, a first face bearing at least one longitudinal row of application elements, and second and third faces each carrying at least one longitudinal row of application elements, in particular two rows, the core bearing for example an additional longitudinal row of application elements located on a ridge between the second and third faces. The axis of each longitudinal row is preferably parallel to the longitudinal axis of the core.

The number of longitudinal rows can be even. There may be at least six longitudinal rows of application elements in total. The first face of the core may carry at least two longitudinal outer rows of application elements flanking a longitudinal central row of application elements, in particular axially offset with respect to said two outer rows. By "axially displaced longitudinal row", it should be understood that the application elements of the same rank of the outer rows do not occupy the same position along the longitudinal axis of the core as those of the central row. The application elements of the two outer rows may be semi-conical shaped pins, and those of the central row of pyramidal shape pins.

The application elements of the second and third faces of the core and the ridge between the latter may be conically shaped pins. In a variant, the first face of the core carries a single longitudinal row of blade-shaped application elements, each extending in particular transversely to the longitudinal axis of the core.

These blade-shaped application members may have reinforcements on their sides extending transversely to the longitudinal axis of the core. In a variant, the core may carry blade-shaped application elements making more than one half-turn about its longitudinal axis, for example a complete turn, and forming rings.

In variants, some or all the application elements are pins of any other shape, in particular of cylindrical or tapered, frustoconical, or pyramidal shape, in particular with a hexagonal base. In a further variant, some or all of the application elements are spikes which, in front view, have an asymmetric shape and an outwardly convex edge, tapering over at least a portion of their height in their entirety. away from the soul, and have a decreasing width towards said convex edge. The cross section of the applicator elements, in particular the pins, may be of substantially circular, semi-circular (so-called half-moon), elliptical or semi-elliptical shape, or still be other, for example polygonal, in particular hexagonal.

At least one applicator element may be terminated by a rounded free end, particularly hemispherical, whose radius of curvature may be between 0.04 mm and 0.2 mm. The aforementioned pins of the second and third faces of the core and the ridge between them can be arranged around the longitudinal axis of the core according to circumferential rows of application elements, two consecutive circumferential rows according to the longitudinal axis of the core being angularly offset by a non-zero angle, in particular equal to half the angular pitch between the application elements of a circumferential row.

The spacing between the application elements of the longitudinal rows of the second and third faces and the peak between them may be greater than the spacing between the application elements of the longitudinal rows of the first face, in particular twice as large. "Spacing between the application elements of a longitudinal row" means the distance between two application elements of rows n and n + 1, measured along the longitudinal axis of the row, between two respective median planes of the two application elements. Within the same longitudinal row, the spacing between two application elements, in particular two pins, of ranks n and n + 1, may be between 0.25 mm and 3 mm, better still between 0.65 mm and 2.2 mm.

The arrangement and shape of the application elements according to the faces of the core of the applicator member provide different makeup effects to the user depending on the faces used. The latter can use the first side to load the eyelashes product, and the rest of the application member to separate and curl the eyelashes. At least one applicator element may extend from the core along an axis of elongation locally perpendicular to the surface of the core, at the point of connection of the applicator element to the core. Preferably, the application elements each extend from the core along an axis of elongation locally perpendicular to the surface of the core, at the point of connection of the application elements to the core. This axis of elongation can be radial.

Alternatively, the elongation axis of the applicator elements forms an angle different from 90 ° with the web surface at the point of connection of the application elements to the core.

The height of the application elements may vary from one longitudinal row to another. In the case where the first face of the core carries at least two longitudinal outer rows of application elements flanking a longitudinal central row of application elements, the height of the application elements of the longitudinal rows of the first face can be greater than those of the application elements of the longitudinal rows of the second and third faces and the ridge between them. In the case where the first face of the core carries a single longitudinal row of blade-shaped application elements, the height of these application elements is less than that of the application elements of the longitudinal rows of the second and third faces and the ridge between them. In a variant, the application elements all have the same height from one longitudinal row to the next. The height of at least one application element, preferably of each application element or the majority of the application elements, may be between 0.15 mm and 3.75 mm, better between 0.5 mm and 2.5 mm. By "height of an application element" is meant the distance measured along the axis of elongation of the applicator element between its free end and its base by which it is connected to the core. The height of the application elements may be constant along the longitudinal axis of the core. In a variant, the height of the application elements varies, for example in a monotonous manner, as one moves along the longitudinal axis of the core. Within a longitudinal row, the height of the application elements may decrease towards the distal end of the core, in particular over at least half of the apparent length of the applicator member. The application elements may have a width of between 0.15 mm and 1.2 mm, more preferably between 0.35 mm and 0.85 mm. By "width of an application element" is meant the largest transverse dimension of the application element, in section, along the longitudinal axis of the core. In the case where the first face of the core carries a single longitudinal row of blade-shaped application elements, these application elements may have a length, measured perpendicular to the longitudinal axis of the core, included between 0.5 mm and 4 mm, better between 1 mm and 3.5 mm. The free ends of the application members of the applicator member define an envelope surface of the applicator member, which for example has a general crescent shape in side view.

The envelope surface of the applicator member may be of greater transverse dimension that is substantially constant over at least a portion of the length of the applicator member, in particular over more than half of the portion of the core bearing the application elements.

The core and the application elements may be molded in the same material, or alternatively may be made of at least two different materials. The core and / or the application elements are preferably made of a thermoplastic material, in particular an elastomeric thermoplastic material. In a variant, the applicator member is a twisted core brush. In this case, the core of the applicator member may comprise at least two branches of a wire folded on itself and twisted together, defining turns, and bristles can be caught between the turns of the soul. Applicator The rod may be attached at a second end to a grasping member.

The applicator member may be molded, being in particular made by bi-injection or mono-injection with the rod. The applicator member may be fixed on the rod by force-fitting, cold or hot, overmoulding, stamping, crimping, screwing, especially in the case where the applicator member is a twisted core brush, The core is preferably inserted after its manufacture in a pre-existing housing of the rod. In variants, the applicator member is fixed on the rod by snapping, gluing, welding, stapling, for example by mounting a tip of the applicator member in a housing of the rod. In another variant, the rod is received in a housing provided in the core. The core of the applicator member may be solid, being for example molded with a fixing end to the rod of the applicator. The application elements may be made of a material more or less rigid than a material used to make the rod of the applicator to which the core is connected. The rod may comprise a first portion, rigid, extended distally by a second portion, more flexible, for example elastomer, carrying the applicator member. The apparent length of the applicator member may be between 14 mm and 35 mm, better still between 19 mm and 28 mm.

The applicator can have between 50 and 680 application elements, better between 70 and 420 application elements. Application Device The invention further relates to a device for packaging and applying a cosmetic, makeup or care product to human keratin fibers, in particular eyelashes and / or eyebrows, comprising an applicator according to the invention and a container containing the product to be applied. The gripping member of the applicator may constitute a cap for closing the container.

The container preferably comprises a wiper member adapted to dewater the rod and the applicator member, comprising a wiper lip. The product is preferably a mascara. The invention will be better understood on reading the following detailed description of a nonlimiting example of implementation thereof, and on examining the appended drawing, in which: FIG. a schematic view in elevation, with partial longitudinal section, of an exemplary packaging and application device produced in accordance with the invention; FIG. 2 represents, in isolation, in perspective and in side view, the device of FIG. application and the rod of the device of FIG. 1, FIG. 3 represents, in perspective and in front view, the applicator member and the rod of the device of FIG. 1, FIG. perspective and in plan view, the applicator member of the device of FIG. 1; FIG. 5 represents, in perspective and in a view from below, the applicator member of the device of FIG. FIG. 5A represents a detail of the applicator member of FIG. 5, and - Figure 6 represents in isolation, in perspective and in side view, an alternative embodiment of an applicator member according to the invention.

FIG. 1 shows a device 1 for packaging and application made according to the invention, comprising an applicator 2 and an associated container 3 containing a product P to be applied to human keratin fibers, in particular on the eyelashes and / or the eyebrows, for example mascara or a care product.

The container 3 comprises, in the example considered, a threaded neck 4 and the applicator 2 comprises a closure cap 5 arranged to be fixed on the neck 4 in order to close the container 3 tightly in the absence of use , the closing cap 5 also constituting a gripping member for the applicator 2.

The latter comprises a rod 7, which is connected at its proximal end 12 to the closure cap 5 and, at its distal end 11, to an applicator member 8, comprising a core 10 extending along a longitudinal axis X, central in the example described. The container 3 also comprises a wiper member 6, inserted in the neck 4.

This wiper member 6, which may be of any suitable type, comprises in the example in question a lip arranged to dewater the rod 7 and the applicator member 8 when the applicator 2 is removed from the container 3. The lip defines a wiper orifice 6a of diameter adapted to that of the rod 7. The wiper member 6 may be made of elastomer. The wiping orifice 6a is for example circular in shape.

In the example shown, the rod 7 has a circular cross section but it is not beyond the scope of the present invention when the rod 7 has a different section, the fixing of the cap 5 on the container 3 can then be performed otherwise than by screwing, if necessary. The wiper member 6 is adapted to the shape of the rod 7 and that of the applicator member 8, where appropriate.

Preferably and as in the example considered, the rod 7 comprises a rectilinear portion 7a extending along a rectilinear longitudinal axis Y about two-thirds of the length of the rod, and a curved portion 7b extending along an axis curvilinear longitudinal Z. As shown in particular in Figure 2, the distance dt between the longitudinal axis Y of the straight portion 7a of the rod 7 and the longitudinal axis Z of the curved portion 7b of the rod 7, measured perpendicular to said axis Y, advantageously increases towards the distal end 11 of the rod 7, reaching a maximum Dt at the point of connection of the applicator member 8 to the rod 7, in particular between 1.5 mm and 5.5 mm better between 2.65 mm and 4.5 mm.

Preferably, and as in the example under consideration, the distance d between the longitudinal axis X of the core 10 of the applicator member 8 and the longitudinal axis Y of the rectilinear portion 7a of the rod 7, measured perpendicularly to said Y axis, decreases away from the distal end 11 of the rod 7, over a portion of the length of the applicator member 8. The rod 7 thus advantageously forms a bend at its level. distal end 11.

Preferably and as in the example described, the curved portion 7b of the rod 7 extends along an arc of a circle of constant radius of curvature R1. The cross section of the curved portion 7b of the rod 7 narrows advantageously towards the distal end 11 of the rod 7, as can be seen in FIG. 2.

The longitudinal axis Y of the rectilinear portion 7a of the rod 7 may coincide with the longitudinal axis of the container 3 when the applicator 2 is in place thereon. The rod 7 may comprise, where appropriate, an annular necking on its portion which is positioned opposite the lip of the wiper member 6, so as not to mechanically stress it excessively during storage.

The applicator member 8 may be molded, being for example made by bi-injection or mono-injection with the rod 7. The applicator member 8 may comprise a tip 9 allowing its attachment in a corresponding housing of the rod. 7. Fixing the applicator member 8 in this housing of the rod 7 can be done by any means and in particular by force fitting, latching, gluing, welding stapling or crimping. Preferably, and as in the example under consideration, the longitudinal axis X of the core 10 of the applicator member 8 is curvilinear, as can be seen in FIG. 2, extending along an arc of a circle of radius of curvature R2 constant. The radii of curvature R1 and R2 of the curved portion of the rod and the core of the applicator member are substantially equal in the example described. Preferably, and as in the example under consideration, the longitudinal axis X of the core 10 forms a non-zero angle with the longitudinal axis Y. As can be seen in particular in FIG. 2, the distance d between the longitudinal axis X of the core 10 and the longitudinal axis Y of the rectilinear portion 7a of the rod 7 advantageously passes through a minimum D, at a point of the core 10 located at a distance from its proximal ends 14 and distal 13, half length in the example, then increases towards the distal end 13 of the core 10, for example until reaching again the maximum D. A tangent T to the core 10 of the application member 8 may be parallel to the longitudinal axis Y of the rectilinear portion 7a of the rod 7, in particular the tangent to the curved portion 8a of the applicator member 8 in the case where the latter is curved, as shown in FIG. 2. The angular offset y between the longitudinal axis Y of the rectilinear portion 7a of the rod 7 and a straight line D pass by the distal end 11 of the rod 7 and this axis Y, at the location 7c where the rod 7 begins to curve, can be between 5 ° and 55 °, better between 10 ° and 45 °. The distal end 13 of the core 10 and the distal end 11 of the rod 7 are located, in the example described and as shown in Figure 2, on a straight line Dp parallel to the longitudinal axis Y of the portion rectilinear 7a of the rod 7. The core 10 may extend on the same side of the longitudinal axis Y as the distal end 11 of the rod 7, as can be seen in particular in FIG. 2. As represented in FIG. the distal end 13 of the core 10 may be eccentric with respect to the proximal end 12 of the stem 7. In the example of FIGS. 1 to 5A, the core 10 carries application elements in the form of pins 18, 16, 15 and / or 19, extending from the core 10 and all around it in a plurality of longitudinal rows. The axis of each longitudinal row of application elements is preferably parallel to the longitudinal axis X of the core 10. The apparent length H of the applicator member 8 is for example equal to 26.5 mm . In the illustrated example, the application elements 18, 16, 15 and 19 extend from the core 10 each along an axis of elongation W perpendicular to the surface of the core, at the point of connection of the application elements to the core 10. As can be seen in particular in FIG. 3, the core 10 of the applicator member 8 has, in the example under consideration, a cross section, taken perpendicularly to its longitudinal axis X, of triangular general shape, the core 10 having three faces 21, 22,23. The first face 21 can carry three parallel longitudinal rows 31, 32 33 of application elements 16, 15, including two longitudinal outer rows 31, 33 surrounding a longitudinal central row 32, axially offset with respect to said two outer rows 31, 32 , as particularly visible in Figure 5. As shown in Figures 3 and 4, the second and third faces 22, 23 of the core 10 may each carry two longitudinal rows 34, 35, 37, 38 of application elements 18 , the core 10 bearing an additional longitudinal row 36 of application elements 18 situated on a peak 24 between the second and third faces 22, 23. As can be seen in FIG. 4, the application elements 18 of the second and third faces 22, 23 of the core 10 and the ridge 24 between them may be arranged around the longitudinal axis X of the core 10 in circumferential rows of application elements 18, two consecutive circumferential rows 41, 42 along the longitudinal axis X of the core 10 being preferably angularly offset by a non-zero angle, in particular equal to half the angular pitch between the application elements 18 of a circumferential row 41. The application elements 18, 16 and 15 may have various shapes.

In the example considered, and as visible in particular in FIGS. 4 and 5A, the application elements 18 belonging to the second and third faces 22, 23 and to the peak 24 are of conical shape, the application elements 16 belonging to the rows 31, 33 of the first face 21 are of semi-conical shape, and the application elements 15 belonging to the central row 32 of the first face 21 are of pyramidal shape.

The spacing Spi between the application elements 18 of the longitudinal rows of the second and third faces 22, 23 and the peak 24 between the latter is greater, in the example under consideration, at the spacing Sp2 between the application elements. 16, 15 of the longitudinal rows of the first face 21, especially twice as large. The height of the application elements 16, 15 of the longitudinal rows 31, 32, 33 of the first face 21 is greater, in the example described, than those of the application elements 18 of the longitudinal rows 34, 35, 36, 37 , 38 of the second and third faces 22, 23 and the peak 24 therebetween, as can be seen in FIG. 3. In a variant that is not illustrated, the application elements 18, 16, and 15 all have the same height. one longitudinal row to another.

In the example considered, the height of the application elements 18, 16 and 15 is constant along the longitudinal axis X of the core 10, within each longitudinal row. In a variant not shown, the height of the application elements 18, 16 and 15 varies as one moves along the longitudinal axis X of the core 10.

The height of the application elements 18, 16 and 15 may be between 0.5 mm and 2.5 mm. In the variant shown in Figure 6, the first face 21 of the core 10 carries a longitudinal row 39 of blade-shaped application members 19, each extending transversely to the longitudinal axis X of the soul 10. These application elements 19 comprise, in the example described, reinforcements 19a on their sides extending transversely to the longitudinal axis X. The height of these application elements 19 is advantageously lower than that of the elements d application 18 longitudinal rows 34, 35, 36, 37, 38 of the second and third faces 22, 23 and the peak 24 between them. In the examples considered, the free ends 28 of the application elements 18, 16, 15 and / or 19 define an envelope surface S of the applicator member 8, of longitudinal axis coinciding with the longitudinal axis X of the 10, non-symmetrical about said X axis, having a general crescent moon shape, in side view as in Figure 2. The application elements 18, 16, 15 and / or 19 are made in the example considered, in one piece by molding thermoplastic material with the core 10. Can be used to mold the applicator member 8 any thermoplastic material, relatively rigid or not, for example SEBS, silicone, latex , a reinforced slip material, butyl, EPDM, a nitrile, a thermoplastic elastomer, a polyester, polyamide, polyethylene or vinyl elastomer, a polyolefin such as PE or PP, PVC, PVC EVA, PS, SEBS, SIS, PET, POM, PU, SAM, PA, PMMA. It is also possible to use a ceramic, for example based on alumina, a resin, for example of the urea-formaldehyde type, possibly a graphite-laden material. It is possible to use the materials known under the trade names Teflon, Hytrel, Cariflex®, Alixine, Santoprene, Pebax® and Pollobas, this list not being limiting. In a variant not shown, the applicator member 8 is a twisted core brush. In this case, the core 10 of the applicator member 8 can comprise at least two branches of a wire folded on itself and twisted together, defining turns, and bristles can be caught between the turns of the core 10. To use the device 1, the user removes the closure cap 5 and extracts the applicator member 8 from the container 3. The user can use the first face 21 to load the eyelashes and / or the eyebrows in product P, and the rest of the applicator member 8 for separating and bending eyelashes and / or eyebrows. Thanks to the elbow between the rod 7 and the applicator member 8, the user can in particular reach the eyelashes at the outer and inner corners without being bothered by the rod 7 touching his cheek.

Of course, the invention is not limited to the embodiments which have just been described. The applicator member 8 may be vibrating, that is to say that it may be applied to it during application, combing or sampling of the product P, for example as described in application WO 2006 / 090,343.

In another variant, the applicator member 8 may be heated, that is to say comprise a heating element for heating the keratinous fibers, the eyelashes and / or the eyebrows, and / or the application elements. , 16, 15 and / or 19 and / or the core 10 of the applicator member 8. The applicator member 8 can comprise any bactericidal agent such as silver salts, copper salts, preservatives as well as at least one preservative agent of the product P. The core 10 and / or the application elements 18, 16, 15 and / or 19 may, in addition, comprise particles, for example a filler, in particular a magnetic compound, bacteriostatic or moisture absorber, or a compound for creating on the surface of the application elements 18, 16, 15 and / or 19 a roughness or to promote the sliding of the eyelashes and / or the eyebrows on the elements of application. At least one of the core 10 and an applicator element 18, 16, 15 or 19 may be flocked, or receive any hot or mechanical treatment.
