Description

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

The container is conventionally provided with a wiper member which wipes the rod of the applicator during its extraction from the container. The behavior of the applicator member through the wiper member depends on many factors such as the shape and nature of the lip of the wiper member and the arrangement of the application elements on the wiper member. the implementing body.

A compromise must be found regarding the amount of product that is left on the applicator for makeup. A too vigorous spin of the application member makes the latter too little load and requires the user to frequently plunge the applicator into the container. Insufficient wringing leaves an excess of product difficult to manage and may lead to packets of product present on poorly separated eyelashes. Applications EP 1 070 466, WO 01/05272 and WO 01/05273 are known applicators comprising application elements located on one side of a core, consisting of a base surmounted by a substantially shaped body. cylindrical or conical. There is a need to further improve the applicators for the application of a product, on the eyelashes and / or the eyebrows, to improve their performance, and more particularly to promote the creation on the application member of zones more loaded product, which allow easy makeup and a fast and abundant load of eyelashes and / or eyebrows, while maintaining a high capacity of separation of eyelashes and / or eyebrows.

The invention aims to meet this objective and has the object, according to one of its aspects, an applicator for applying a cosmetic product, makeup or care, on the eyelashes and / or the eyebrows, comprising a body of molded application comprising: - a core extending along a longitudinal axis, - pins carried by the core and arranged in a plurality of longitudinal rows, applicator in which, in a longitudinal row on at least two around the longitudinal axis of the core, at least one pin is reinforced at its base and extends between pins without reinforcement.

Thanks to the invention, the pins which are reinforced bend less during the extraction of the applicator, which tends to reduce the spin of the soul at their level. This makes it possible to obtain, on the applicator member, particularly in the vicinity of these reinforced pins, between the rows of pins and between the nubs of the rows, reservoir zones that are less dewatered during the passage of the applicator. through the wiper member, thus providing for makeup, if desired, a surplus of product over the entire length of the soul and all around it. This surplus of product allows, from the first application, a significant and satisfactory load of product of the eyelashes and / or eyebrows. During makeup, these reservoir areas are gradually emptied of their contents, when the eyelashes and / or the eyebrows come into contact with them. The latter are thus suitably loaded with product without the user having to recharge the applicator too frequently by reintroducing it into the container. In addition, the reinforced pimples can help smooth the product on the eyelashes and separate them by creating an additional contact surface with the eyelashes.

It is possible to play during the manufacture of the applicator member on the height and shape of the reinforcements, and on the number and arrangement of reinforced pins, to adjust the level of the product load of the applicator after spinning. By "Payne longitudinal axis" is meant the line joining all the centroids of the cross sections of the soul. The longitudinal axis may be a central axis or an axis of symmetry for the core, especially when the core has a circular cross section or generally polygonal regular shape. 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 all cross sections of the soul. Preferably, the longitudinal axis of the core is rectilinear.

By "pin" means an individualizable projecting element intended to come into engagement with the eyelashes and / or the eyebrows. Reinforced pimples Preferably, on more than half the length of a longitudinal row, one picot out of two is reinforced at its base.

Also preferably, in every other longitudinal row, every second pin is advantageously reinforced at its base, with the exception of the pin closest to the distal end of the core, which may remain unprepared. reinforcement.

In a variant, several reinforced pins follow each other in the same longitudinal row. Within a longitudinal row, the ratio between the number of reinforced barbs and the total number of barbs of this row can be between 1/3 and 3/4, better 3/8 and 5/8. The adjacent pins of a reinforced pin may be devoid of reinforcement, including the two pins which are adjacent to it within the circumferential row to which the reinforced pin belongs, and the two nearest pins in the two adjacent longitudinal rows. By "circumferential row of pins", or ring of pins, it is necessary to understand a row formed by pins occupying the same axial position on the longitudinal axis of the core. A circumferential row on two advantageously comprises reinforced pins. The circumferential rows of the proximal and distal ends of the core are preferably devoid of reinforced pins.

The reinforced pins advantageously comprise a reinforcement at their base extending over only a portion of the height of the reinforced pin. The reinforced pins may have a shoulder defining the reinforcement of the rest of the reinforced pin. This shoulder may extend perpendicular to the axis of elongation of the pin.

The reinforced pins preferably have, above the corresponding reinforcements, a serni-conical or semi-prismatic shaped body, that is to say for example having a first planar face and a second rounded or prismatic face. In one variant, the reinforced pins have, above corresponding reinforcements, a body of any other shape, in particular a form of revolution, cylindrical or tapered, for example conical, or a frustoconical or pyramidal shape, in particular with a hexagonal base. The reinforced pins advantageously extend along an axis of rectilinear elongation. The reinforcements of the reinforced pins may have a cross section of elongate shape, preferably elongate in the direction of the longitudinal axis of the core. This can increase the flexural strength against a force exerted in the direction of the longitudinal axis of the core, which is the case when extracting the applicator. Reinforcements of the reinforced spikes may have a cross section that increases in proximity to the core.

Reinforcements of the reinforced pins advantageously have a cross section, taken perpendicular to the axis of elongation of the pins, substantially rectangular and, when viewed from the front in a direction perpendicular to the major axis along which extend the long sides of their section cross section, an isosceles trapezium profile. In variants, the reinforcements of the reinforced pins have, in front view, another shape, for example a triangular or rectangular profile. Preferably, the major axis along which extend the long sides of the cross section reinforced reinforcement pins is oriented parallel to the longitudinal axis of the core. In a variant, this major axis is oriented obliquely or perpendicularly to the longitudinal axis of the core. Reinforcements of the reinforced barbs are advantageously not contiguous to other barbs at their base. The height of the reinforcements may be less than half the total height of the reinforced pins. By "reinforcement height" is meant the distance measured along the axis of elongation of the pin between the top of the reinforcement and its base through which it is connected to the core. By "total height of a reinforced pin" means the distance measured along the axis of elongation of the pin between its free end and the base of the reinforcement by which it is connected to the core. The ratio between the height of each reinforcement and the total height of the pin that it reinforces is preferably between 0.1 and 1.7, more preferably between 0.3 and 1.4. The height of the reinforcements may be constant along the longitudinal axis of the core, being in particular between 0.1 mm and 2.5 mm, better between 0.17 mm and 1.55 mm. In a variant, the height of the reinforcements varies along the longitudinal axis of the core, for example within one or more longitudinal rows and / or from one longitudinal row to the other. The reinforced pins are advantageously of the same height as the pins without reinforcement. The thickness of the reinforcements may be between 0.35 mm and 1.2 mm, better still between 0.45 mm and 1 mm, being in particular equal to about 0.85 mm. By "thickness of a reinforcement" is meant the largest transverse dimension of the reinforcement, in section perpendicular to the longitudinal axis of the core. The width of the reinforcements at their base is advantageously constant along the longitudinal axis of the core. By "width of a reinforcement at its base" is meant the transverse dimension of the reinforcement, in section along the longitudinal axis of the core, at the connection point of the reinforcement on the core. The width of the reinforcements at their base may be between 0.35 mm and 1.5 mm, for example equal to about 0.85 mm. The width of the reinforcements at their apex can be between 0.3 mm and 1.2 mm, for example equal to about 0.7 mm. By "width of a reinforcement at its top" means the transverse dimension of the reinforcement, in section along the longitudinal axis of the core, at the point of connection with the rest of the pin it reinforces. Soul and Spikes The spikes advantageously extend from the core and all around it. The number of longitudinal rows can be even. There may be at least eight longitudinal rows of pins in total, including sixteen rows including eight longitudinal rows with reinforced pins. The longitudinal rows are preferably rectilinear. The axis of each longitudinal row is preferably parallel to the longitudinal axis of the core. Each longitudinal row is preferably axially offset with respect to the consecutive longitudinal row. By "axially offset longitudinal rows", it should be understood that the pins of the same rank in these rows do not occupy the same position along the longitudinal axis of the core. The pins of the same rank of the longitudinal rows without reinforced pins can all occupy the same axial position along the longitudinal axis of the core. Reinforced pins having the same rank of the longitudinal rows having reinforced pins may all have the same axial position along the longitudinal axis of the core. The pins of two adjacent longitudinal rows may be non-contiguous at their base. Within the same longitudinal row, the spacing between two n and n + 1 nubs, measured along the longitudinal axis of the row, between the two respective median planes of the two pins, may be between 0 , 5 mm and 2.5 mm, better still between 1 mm and 2 mm, being in particular equal to about 1.7 mm. Within the same longitudinal row with reinforced barbs, the interval between two barbs of rows n and n + 1, one of which is reinforced and the other not, measured along the longitudinal axis of the row between the base of the reinforcement and the base of the adjacent pin, may be between 0.3 mm and 2 mm, better between 0.7 mm and 1.4 mm, being in particular equal to about 1 mm. Within the same longitudinal row with no reinforced pimples, the interval between two pits of ranks n and n + 1, measured along the longitudinal axis of the row, between the two pimple bases facing each other, may be between 0.3 mm and 2 mm, better between 0.9 mm and 1.7 mm, being in particular equal to about 1.2 mm. The implantation of the pins may be such that the angular offset around the longitudinal axis of the core, between the pins of two consecutive rings of pins, is not zero, preferably being equal to half the angular pitch fl between two consecutive pins 10 of the same ring. At least one pin may extend from the core along an axis of elongation perpendicular to the surface of the core at the point of connection of the pin to the core. Preferably, the spikes each extend from the core along an axis of elongation perpendicular to the surface of the core, at the point of connection of the spikes to the core. This axis of elongation may be radial. The surface of the core on which the pins are connected may be a surface of revolution. Alternatively, the axis of elongation of the pins forms an angle different from 90 ° with the surface of the core at the point of connection of the pins to the core. The height of at least one pin, better of each pin or the majority of pins, measured from the core, may be between 0.5 mm and 3.5 mm, better between 0.75 mm and 2 mm. Preferably, the height of the pins varies, for example monotonically, as one moves along the longitudinal axis of the core. Within a longitudinal row, the height of the pins preferably decreases towards the distal end of the core, especially over at least half the apparent length of the applicator member. In a variant, the height of the pins is constant along the longitudinal axis of the core. The pins of the longitudinal rows without reinforcement are advantageously of conical shape. In variants, said spikes are of any form, in particular of cylindrical or tapered, semi-conical, frustoconical or pyramidal shape, in particular with a hexagonal base. In a further variant, the pins have, in front view, an asymmetric shape and an outwardly convex edge, tapering over at least a portion of their height away from the core and have a decreasing width. towards said convex edge. The cross section of the pins of longitudinal rows without reinforcement may be of substantially circular, semicircular (so-called half-moon), elliptical or semi-elliptical shape, or still be other, for example polygonal, in particular hexagonal. The pins without reinforcement belonging to a longitudinal row having reinforced pins are advantageously of the same general shape as the body of said reinforced barbs of the row above the reinforcement, being in particular of semi-conical shape. The cross section of the pins without reinforcement belonging to a longitudinal row having reinforced pins is advantageously semicircular (so-called half-moon). Within the longitudinal rows having reinforced pins, in the case where the pins of these rows all have a semi-conical shape, the flat faces of each pin are advantageously oriented in the same circumferential direction around the longitudinal axis of the spring. . At least one pin may be terminated by a rounded free end, particularly hemispherical, whose radius of curvature may be between 0.05 mm and 0.2 mm, being for example equal to about 0.15 min. Some pins of the applicator, in particular the pins belonging to the longitudinal rows without reinforcement, may have a thickness of between 0.2 mm and 0.85 mm, better still between 0.45 mm and 0.75 mm, being in particular equal to About 0.5 mm. "Thickness of a pin" means the largest transverse dimension of the pin, in section, perpendicular to the axis of elongation of the pin and the longitudinal axis of the core. The thickness of the pins without reinforcement belonging to the longitudinal rows comprising reinforced pins may be equal to half the thickness of the pins belonging to the longitudinal rows devoid of reinforcement, especially in the case where the pins without reinforcement belonging to the longitudinal rows having reinforced pins are of serni-conical shape. The pins without reinforcement may have a width of between 0.2 mm and 0.8 mm, better between 0.35 mm and 0.65 mm, being in particular equal to about 0.5 mm. By "width of a pin" means the largest transverse dimension of the pin, in section along the longitudinal axis of the core. The free ends of the pins of the applicator member define an envelope surface of the applicator member, which is for example cylindrical of revolution 5 over at least part of its length. 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 pimples. The envelope surface may also have a cross section which varies over all or part of the length of the applicator member. The cross section of the envelope surface may for example admit one or more extrema and for example at least one local minimum and two local maxima. The diameter of the envelope surface passing through the apex of the smaller height pins may be between 4 mm and 7.5 mm, being for example equal to about 5.5 mm. The diameter of the envelope surface of the applicator member passing through the apex of the spikes of greater height may be between 6.5 mm and 12 mm, being for example equal to 7.7 mm approximately. The core may have a cross section, taken perpendicularly to its longitudinal axis, of any shape, in particular circular. The largest cross section of the core, namely its diameter in the case where the cross section of the core is of circular shape, can be between 1.8 mm and 3.2 mm, being in particular equal to 2 , About 8 mm. The core, pins and reinforcements and reinforced pin bodies may be molded from the same material, or alternatively may be made of at least two different materials. The core and / or the pins and / or the reinforcements are preferably made of a thermoplastic material, in particular an elastomeric thermoplastic material. Applicator The applicator may comprise a rod carrying at a first end 30 the applicator member and fixed at a second end to a gripping member. The core may be solid, being for example molded with a fixing end to the rod of the applicator.

The applicator member may be fixed on the rod by snapping, gluing, welding, crimping, stamping, stapling, forced insertion, cold or hot, for example by mounting a tip of the application member. in a housing of the stem. Alternatively, the rod is received in a housing provided in the core.

The rod and the applicator member may also be molded in one piece, in the same thermoplastic material or not. The pins and / or their reinforcements 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 core may extend along a longitudinal axis making in at least one point of its length a non-zero angle with the longitudinal axis of the rod to which is fixed the core. The applicator member may be bent at its connection to the rod. 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 15 mm and 35 mm, better still between 22 mm and 29 mm, for example equal to approximately 24.5 mm. The applicator may comprise between 108 and 600 pins, for example between 128 and 256 pins. The first pin along the longitudinal axis of the core from the rod may be disposed at a non-zero distance from the proximal end of the core, in particular between 0.2 mm and 0.7 mm. The last pin along the longitudinal axis of the core from the rod may be disposed at a non-zero distance from the distal end of the core, in particular between 0.25 mm and 0.9 min. The invention also relates to a device for packaging and applying a product on the eyelashes and / or the eyebrows, comprising an applicator according to the invention, as defined above, and a container containing the product to apply. 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 ratio between the diameter of the circumscribed circle centered on the longitudinal axis of the core and passing through the vertices of the reinforcements, in cross-section perpendicular to the longitudinal axis of the core, and the diameter of the orifice defined by the lip of the wiper member may be between 0.7 and 1.45.

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 diagrammatic elevational view, with partial longitudinal section, of an example of a packaging and application device produced in accordance with the invention; FIG. 2 represents, in isolation, in perspective, the applicator member of FIG. FIGS. 2A and 213 represent details of the applicator member of FIG. 2; FIG. 3 is a section III-III of a detail of the applicator member of FIG. 2; FIG. 4 is a section along IV-IV of a detail of the applicator member of FIG. 2; FIG. 5 is a section along VV of the applicator member of FIG. 2; and FIG. FIG. 6 is a flat developed view illustrating the arrangement of a portion of the pins on the surface of the core of an applicator member. ion 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 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 closing cap 5 arranged to be fixed on the neck 4 in order to close the container 3 in a sealed manner in the absence of use, the closure cap 5 also constituting a gripping member for the applicator 2. The latter comprises a rod 7 of longitudinal axis Y, which is connected at its upper end to the closure cap 5 and, at its lower end, to an applicator member 8. The latter comprises a core 10 carrying pins 18, 15 and 16, extending from the core 10 and all around thereof. As seen in Figure 2, the first pin 18 along the longitudinal axis X of the core 10 from the rod 7 is disposed at a distance d, not zero from the proximal end 11 of the core, for example equal to about 0.51 mm. The last pin 15 along the longitudinal axis X of the core 10 starting from the rod 7 is disposed at a non-zero distance dd from the distal end 12 of the core 10, for example equal to about 0.55 mm . 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 application 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. The diameter of the wiping orifice 6a is typically between 3 and 5.5 mm, being for example of the order of 4.5 mm or 5 mm. 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 to that of the applicator member 8, as the case may be. Preferably and as in the example considered, the longitudinal axis Y of the rod 7 is rectilinear and coincides with the longitudinal axis of the container 3 when the applicator 2 is in place thereon, but it does not leave the of the present invention when the rod 7 is non-rectilinear, forming for example a bend. 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 comprise, as illustrated in FIG. 2, a nozzle 9 enabling it to be fixed in a corresponding housing of the rod 7. The fixing of the applicator member 8 in this housing of the rod 7 can be done by any means and particularly by force fitting, latching, gluing, welding stapling or crimping.

Referring to Figure 2, we see that the core 10 is of elongate shape along a longitudinal axis X, which is rectilinear in the example described. The longitudinal axis X may be central, as illustrated. The apparent length H of the applicator member 8 is for example equal to 24.5 mm. In the example illustrated, the pins 18, 15 and 16 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 pins to the core. 10. As can be seen in particular in FIG. 2, in a longitudinal row 17 of two, a pin 16 of two is reinforced at its base and extends between two pins 15 without reinforcement, with the exception of the pin closer to the distal end 12 of the core 10, which remains devoid of reinforcement. The circumferential rows located at the proximal ends 11 and distal 12 of the core 10 are advantageously devoid of reinforced pins 16.

As can be seen in FIG. 6, a reinforced pin 16 is thus advantageously surrounded by six pins 18, 15 devoid of reinforcement: the two pins 15 which are adjacent to it within the ring 21 of pins to which it belongs, and two pins 18 each belonging to the two adjacent longitudinal rows 19 and 20. Preferably, as in the example described, a ring 21 of pins in two has reinforced pins 16. The pins 18, 15 and 16 can be arranged on the body of application 8 according to a plurality of rectilinear longitudinal rows 17, 19, 20, as can be seen in FIGS. 2 and 6, each longitudinal row 17 of pins being axially offset with respect to the adjacent longitudinal row 19.

The pins 18 of each longitudinal row without reinforcement advantageously all occupy the same axial position along the longitudinal axis X of the core 10, as shown in Figure 6, for example between the longitudinal rows 19 and 20. The pins reinforced 16 of a longitudinal row having reinforced pins on two may all have the same axial position along the longitudinal axis X of the core 10.

In the example under consideration, the number of longitudinal rows is even, being for example equal to sixteen, including eight longitudinal rows comprising reinforced pins 16.

Preferably, the reinforced pins 16 extend along a linear axis of elongation W and advantageously comprise a reinforcement 13 at their base 16a extending over only a portion of their height. The reinforced pins 16 advantageously have a shoulder 16e delimiting the reinforcement 13 of the rest of the reinforced pin. As can be seen in the figures, the reinforced pins 16 have, above the corresponding reinforcements 13, a body 16b of semi-conical shape. Reinforcements 13 reinforced pins 16 may have a cross section of elongated and substantially rectangular shape, visible in particular in Figure 6. When viewed from the front in a direction perpendicular to the axis Z along which extend the long sides 13a of their transverse section, the reinforcements 13 have an isosceles trapezium profile, visible in FIG. 3, their cross section increasing towards the core 10. Preferably, the axis Z along which the long sides 13a of the cross-section of the reinforcements 13 of the reinforced pins 16 is oriented parallel to the longitudinal axis X of the core 10. As can be seen in FIG. 2B, the lateral flanks 13g of the reinforcements 13 when these are observed from the front, can be connected by roundings 13b to the front face 13f of the reinforcement. The lateral flanks 13g are planar, as is the front face 13f. As shown in Figure 6, the body 16b of each reinforced pin 16 may extend in the extension of the reinforcement 13 above it on the side of the flat face 16d of the pin 16. On the opposite side, the body 16b can form a recess db width with the reinforcement 13 above it. The width db is for example between 0.05 mm and 0.65 mm. In a variant, the body 16b of the reinforced pin 16 does not form a recess with the reinforcement 13 above it.

In the example considered, the height h ,. reinforcement 13 is less than half the total height h, reinforced pins 16, as shown in Figure 3. The ratio h, / h, between the height of each reinforcement 13 and the total height of the pin 16 that he strength is between 0.1 and 1.7 better between 0.3 and 1.4. The height h, reinforcements 13 may be constant along the longitudinal axis X of the core 10, as in the example described, being for example between 0.1 mm and 2.5 mm, better between 0, 17 mm and 1.55 mm. In a variant not shown, the height h ,. reinforcement 13 varies along the longitudinal axis X of the core 10, for example within one or more longitudinal rows 17 and / or from one longitudinal row to the other.

The reinforced pins 16 are advantageously of the same height as the pins 18, 15 devoid of reinforcement. The thickness e, reinforcements 13, visible in Figure 6, may be between 0.45 mm and 1.5 mm, being for example equal to 0.85 mm.

The width 1b of the reinforcements 13 at their base 13a is advantageously constant along the longitudinal axis X of the core 10. The width 1b of the reinforcements 13 at their base 13a may be between 0.35 mm and 1.5 mm. , being for example equal to about 0.85 mm. The width l of the reinforcements 13 at their apex 13e can be between 0.3 mm and 1.2 mm, being for example equal to about 0.7 mm.

The evkea ratio between the diameter qi 'of the circumscribed circle centered on the longitudinal axis X of the core 10 and passing through the vertices 13e of the reinforcements 13 and the diameter ÇOa of the orifice 6a defined by the lip of the organ wiper 6 can be between 0.7 and 1.45. The pins 18 and 15 may have various shapes. In the example considered, and as visible in particular in Figure 4, the pins 18 belonging to the longitudinal rows without reinforcement are conical. As can be seen in particular in FIG. 2, the pins 15 without reinforcement and belonging to the longitudinal rows comprising reinforced pins 16 are of semi-conical shape, the flat faces of each pin being advantageously oriented in the same circumferential direction.

The pins 18, 15 and 16 of two longitudinal rows 17, 19 adjacent may be non-contiguous to their base, as shown in Figure 2A. The reinforcements 13 of the reinforced pins 16 are advantageously all non-contiguous at their base. As can be seen in FIG. 2, the height of the spikes 18, 15 and 16 may vary as one moves along the longitudinal axis X of the core 10. The height may decrease towards the distal end 12 of the core 10, in order to facilitate the engagement in the container 3. The height hp of the pins 18, 15 devoid of reinforcement can be between 0.5 mm and 3.5 mm, better between 0.75 mm and 2 mm. mm. With reference to FIG. 5, the diameter 92 of the envelope surface formed by the pins 18, 15 and 16 of smaller height can be between 4 mm and 7.5 mm, being for example equal to 5.5 mm . The diameter 91 of the envelope surface of the applicator member 8 formed by the pins 18, 15 and 16 of greater height can be between 6.5 mm and 12 mm, for example equal to 7.7 mm approximately .

The thickness ep of the pins 18 belonging to the longitudinal rows without reinforcement may be between 0.45 mm and 0.75 mm, being for example equal to about 0.5 mm, as in the example considered. The thickness of the nubs 15 without reinforcement belonging to the longitudinal rows comprising reinforced pins 16 may be equal to half the thickness ep of the nubs 18 belonging to the longitudinal rows devoid of reinforcement, especially in the case where the nubs 15 lacked reinforcement belonging to the longitudinal rows with reinforced pins 16 are of semi-conical shape. The width 1 of a pin 18, 15 without reinforcement may be between 0.2 mm and 0.65 mm, being for example equal to about 0.5 mm. As can be seen in FIG. 5, the implantation of the pins 18, 15 and 16 may be such that the angle α about the longitudinal axis X of the core 10, between two consecutive rings 21 and 22 of pins 18, 15 and / or 16, each formed by pins 18, 15 and / or 16 occupying the same axial position on the longitudinal axis X of the web 10, being non-zero, being for example equal to half the angular pitch fi between two consecutive nubs of a crown. In the same longitudinal row 17 or 19, the spacing Sp between two consecutive pins 18 or 15 and 16 may be between 1 mm and 2 mm, being for example equal to 1.7 mm, as in the example described. Within the same longitudinal row 17 having pins 16 having a reinforcement 13, the gap Sr between two n-rows of n and n + 1, one of which includes a reinforcement 13 and the other 15 is The gap, measured between the base 13a of the reinforcement 13 and the base 15a of the adjacent pin, may be between 0.7 mm and 1.4 mm, for example equal to about 1 mm. Within the same longitudinal row 19 without pins having a reinforcement, the interval Sb between two nubs 18 of rows n and n + 1, measured between the two bases 18a of the pins 18 facing each other, can be between 0.9 mm and 1.7 mm, being for example equal to about 1.2 mm. In the example considered. the free ends 28 of the pins 18, 15 and 16 define an envelope surface S of the applicator member 8, of rectilinear longitudinal axis and coincident with the longitudinal axis X of the core 10, symmetrical of revolution around said X axis.

The pins 18, 15, 16 and the reinforcements 13 are made, in the example in question, in one piece by molding thermoplastic material with the core 10. It can be used to mold the application member 8 any material thermoplastic, relatively rigid or not, for example SEBS, silicone, latex, reinforced slip material, butyl, EPDM, nitrile, thermoplastic elastomer, polyester, polyamide, polyethylene elastomer or vinyl, a polyolefin such as PE or PP, 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, optionally a graphite-filled material. The materials known under the trade names Teflon, Hytrel®, Cariflee, Santoprene, Pebax and Pollobae can be used, this list not being limiting. To use the device 1, the user unscrews the closure cap 5 and extracts the applicator member 8 from the container 3.

After passing through the applicator member 8 of the wiper member 6, a certain quantity of product P remains around the pins 16 having a reinforcement 13, the reinforced pins 16 do not fold at their base during the passage of the wiper member 6, creating product reservoirs P along the entire length of the core 10 and on all sides, for satisfactorily loading the eyelashes and / or eyebrows product P.

Of course, the invention is not limited to the embodiment which has 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.

As a further variant, the applicator member 8 may be rotatable, that is to say it may be rotated about the longitudinal axis X of the core 10, for example during the application, combing or removal of the product P. In another variant, the applicator member 8 may be heated, that is to say include a heating element for heating the keratinous fibers, the eyelashes 30 and / or the eyebrows, and / or the pins 18, 15, 16 and / or the core 10 and / or the reinforcements 13 of the applicator member 8. It is also possible that the applicator member 8 either vibrating, rotating and heating, or solely vibrating and rotating, or solely vibrating and heating, or only rotating and heating, or solely vibrating or solely rotating or heating only. The applicator member 8 may comprise any bactericidal agent such as silver salts, copper salts, preservatives and at least one agent for preserving the product P. The core 10 and / or the pins 18, 15, 16 and / or the reinforcements 13 may, in addition, comprise particles, for example a filler, in particular a magnetic, bacteriostatic or moisture-absorbing compound, or a compound intended to create on the surface spikes 18, 15, 16 and / or reinforcements 13 roughness or to promote the sliding eyelashes and / or eyebrows on the pins and / or reinforcements. At least one of the core 10 and a pin 18, 15, 16 and a reinforcement 13 can be flocked, or receive any hot or mechanical treatment. The phrase "comprising one" shall be understood as being synonymous with "comprising at least one", and "between" means inclusive, unless the contrary is specified.
