Description

TECHNICAL FIELD

[0001] The present invention relates to an applicator device for applying a fluid or paste product on keratin fibers or on the skin. In particular, the present invention relates to an applicator device for applying a skincare, makeup or care product on the hair, the eyelashes, the eyebrows, the skin or the lips. BACKGROUND

[0002] Currently, applicator devices exist for applying a product of fluid or paste type on keratin fibers, such as mascara brushes, comprising a central core in elongated form extending along a longitudinal axis and at least one row of elongated spikes comprising a first end embedded in the core and a second free end. Generally, the spikes and the core are formed in a single piece by molding, forming an integral body with each other. For example, document FR 2 937 514 describes such an applicator device. One drawback of products of this type is that the spikes are monolithic and that the section of the end of the spikes embedded in the core is larger than the section of the spikes at their free end, especially for reasons of molding technique. Thus, the spikes are relatively inflexible whatever the material used. Indeed, in use of the applicator device, the spikes will offer a certain resistance when they come into contact with the keratin fibers (or the skin) either frontally or laterally. Thus, the spikes can prick the eyelids when making up the eyelashes, or prick the skin when treating the eyebrows, or prick the lips or the scalp.

[0003] Document US 2012 / 0170965 provides a solution to this comfort problem, which describes a spike comprising a conical anchoring end whose section is still as large as before, and a very flexible free end which can be bent back so that the tip does not prick the skin. However, this solution has two drawbacks. The first is that the flexibility of the free end and the fact that it is bent back no longer allow the keratin fibers to untangle during the application. The other drawback is that the base of the spike is rigid and that the product present between the rigid bases of the spikes cannot rise to the free end of the spikes to be applied to the keratin fibers or the skin. SUMMARY

[0004] One object of the present invention is to provide an applicator device for applying a fluid or paste product which makes it possible to optimally apply the product while bringing an enhanced comfort to its user.

[0005] To this end, according to the application, there is provided an applicator device for applying a fluid or paste product to keratin fibers or to the skin (epidermis), comprising an elongated core extending along a longitudinal axis X and in the form of a longitudinal cylinder and a plurality of spines distributed on the core, each spine extending from an anchoring end in the core to a free end and being integral with the core, characterized in that each spine comprises, from the anchoring end to the free end, a proximal segment, a bridge and a distal segment, at least one of the proximal segment and the bridge forming a flexible connection.

[0006] Thus, this structure of the spine makes it possible to retain a sufficiently rigid distal segment to allow it to disengage the keratin fibers when they are guided, the flexible connection formed by the proximal segment and / or the bridge acting as a damper so that, when the free end of the spine comes into contact with the underlying skin, it is able to eliminate the sensation of stinging. The deformation obtained in use at the base of the spine makes it possible for the product present at this tip to rise to the free end of the spine.

[0052] DETAILED DESCRIPTION

[0053] With reference to Figure 15 A first embodiment of an applicator device 1 according to the application will now be described. Here, the applicator device 1 according to the application is a mascara brush. Here, it comprises a core 2 extending longitudinally along a longitudinal axis X. The core 2 can have a cross-section that is constant or not constant over the entire length. In the most common embodiment, the cross-section is constant, or the cross-section decreases gradually from the proximal end, which engages with the tube and / or the holding shaft, to the distal free end. Typically, the core 2 has a generally cylindrical shape, the axis of rotation of which is preferably the longitudinal axis X. Thus, the cross-section of the core 2 can have a circular, polygonal, elliptical or other form. It can be axisymmetric. The core 2 can be solid or hollow. The person skilled in the art will choose the most suitable core according to the economic and / or technical constraints.

[0054] Moreover, the applicator device 1 according to the application comprises a plurality of spikes 10 distributed on the core 2. The spikes 10 extend protrusively from the peripheral surface of the core 2. The spikes 10 are, for example, formed integrally with the core 2. Notably, the spikes 10 are obtained by moulding together with the core 2. Here, as illustrated, the spikes 10 are distributed in adjacent rows extending longitudinally in pairs parallel to the longitudinal axis X. The spikes 10 of the same row extend in the same way from the core 2 parallel to each other according to the same orientation. Here, when considering two adjacent rows, the spikes 10 of one of the adjacent rows are oriented differently from the spikes 10 of the other of the adjacent rows, for example, as illustrated in Figure 1. Figure 15 ​As a variant, the orientation is 90°.

[0055] With reference to figure 1, a first embodiment of a spike 10 of an applicator device 1 according to the application is now described in more detail. The spike 10 comprises an anchoring end 14 and a free end 12. The anchoring end 14 is connected to the core 2 of the applicator device 1 according to the application. The spike 10 thus extends from the anchoring end 14 to the free end 12, here in the plane of symmetry P. From the anchoring end 14, the spike 10 comprises a proximal segment 13, followed by a bridge 15, then by a distal segment 11, and finally by the free end 12. The bridge 15 serves as a connection between the proximal segment 13 and the distal segment 11. The distal segment 11 here comprises a main extension in the form of a taper. The proximal segment 13 here has a curved form like a cross, the vertex of which is here at a distance from the bridge 15, then the height of the bridge 15 being lower than the height of this vertex. As a variant, the bridge 15 is at the height of the vertex of the curved form of the proximal segment 13. This curved form of the proximal segment 13 enables it to give the proximal segment 13 a certain flexibility. Thus, the proximal segment 13 forms a flexible connection between the anchoring end 14 (and thus the core 2 of the applicator device 1 according to the application) and the bridge 15.

[0056] According to different variant embodiments, the bridge 15 is positioned on the free end of the curved form of the proximal segment 13, this free end of the curved form of the proximal segment 13 forming a skirt in a direction that can be parallel to the axis X (that is to say, the bridge 15 is at the height of the vertex of the curved form of the proximal segment 13), or in a direction that brings it closer to the axis X (the height at which the bridge 15 is located being lower than the height of the vertex of the curved form of the proximal segment 13), or conversely, in a direction that brings it away from the axis X.

[0057] According to the variant embodiment of the spike 10 illustrated in Figure 2 According to the variant embodiment of the spike 10 illustrated in

[0058] According to the second variant embodiment of the spike 10 illustrated in Figure 3 According to the second variant embodiment of the spike 10 illustrated in

[0059] According to a third variant embodiment of the spike 10 shown in figure 4, the proximal segment 313 of the spike 310 is made thinner and has a flat face 301 which is contained in the plane of symmetry P. Moreover, as such, the distal segment 311 is made thinner and has a flat face 302 which is also contained in the plane of symmetry P. This arrangement is such that the proximal segment 313 extends on one side of the plane of symmetry P, while the distal segment 311 extends on the other side of the plane of symmetry P. Moreover, this flat face 302 is continuous in the bridge 315, thereby providing the latter with a flexibility which is added to the flexibility of the proximal segment 313. Again, as for the bridges 15, 215, according to different variant embodiments, the bridge 315 is positioned on the free end of the curved form of the proximal segment 313, this free end of the curved form of the proximal segment 313 forming a skirt in a direction which can be parallel to the axis X (that is to say, the bridge 315 is located at the height of the vertex of the curved form of the proximal segment 313), or closer to the axis X (the bridge 315 is located at a height which is lower than the height of the vertex of the curved form of the proximal segment 313), or, on the contrary, further away from the axis X.

[0060] Figure 5 shows a fourth variant embodiment of the spike 10. The spike 410 differs from the spike 10 in that it comprises a distal segment 11 whose main extension is oriented at an angle a with respect to the plane of symmetry P. In Figure 6 In the variant 411 shown, the main extension is in the plane of symmetry P, but at an angle a with respect to the vertical. More generally, in this variant embodiment, the main extension has an orientation which is contained within the cone angle at the vertex, which here is located at the height of the bridge 15.

[0061] In Figure 7 to Figure 9 , a fifth variant of the spike 10 is shown, as well as an inclination. The spike 10 comprises a distal segment comprising a main extension 11a and a secondary extension 11b which extend from the bridge 15 and which form an angle with respect to each other. The spike 10 comprises a distal segment comprising a main extension 11a and a secondary extension 17 which extend from the side wall of the main extension 11a. The spike 10 comprises a distal segment comprising a main extension 11a and a secondary extension 18 which extend from the proximal segment 13.

[0062] Figure 10A sixth variant embodiment of spike 10 is shown in Figure 12. Spike 104 also comprises a flexible foot 16 at its proximal end segment 13, which extends between the bridge 15 and the core 2 and supports the distal end segment 11. The flexibility of the flexible foot 16 is such that, when the free end 12 of the spike 104 is subjected to pressure, the proximal end segment 13 still forms a flexible connection between the bridge 15 and the anchoring end 14. However, when in use, when the spike 104 comes into contact, at its free end 12, with the lip of a tube stored in the applicator device 1 according to the application and containing a fluid product therein, the flexible foot 16 holds the spike 104 while preventing it from elongating or tilting backwards. Figure 11 and Figure 12 Variant embodiments 105 and 106 of spikes 102 and 101 respectively comprising a flexible foot 16 are shown.

[0063] Figure 13 shows a seventh variant embodiment of spike 10. This variant spike 510 comprises, from the anchoring end 14 to the free end 12, a proximal end segment 513, a bridge 515 and a distal end segment 511. In addition, the spike 510 comprises a lateral face 514 which extends over the entire height of the spike 510 and lies on a circle C. The circle C is in a plane at right angles to the longitudinal axis X, the intersection point of which with the plane in which the circle C lies being on the circle C. This structure of the face of the spike supported by the circle C is described in detail in document FR 2 937 514, which can be consulted for more comprehensive information.

[0064] Again, as for the bridges 15, 215, 315, according to the different variant embodiments, the bridge 515 is positioned on the free end of the curved form of the proximal end segment 513, this free end of the curved form of the proximal end segment 513 forming a skirt in a direction which can be parallel to the axis X (that is to say, the bridge 515 is at the height of the apex of the curved form of the proximal end segment 513), or closer to the axis X (the height at which the bridge 515 is located being lower than the height of the apex of the curved form of the proximal end segment 513), or, on the contrary, further away from the axis X.

[0065] A eighth variant embodiment of spike 10 is shown in Figure 14. The spike 610 of this variant embodiment comprises, from the anchoring end 14 to the free end 12, a proximal end segment 613, a bridge 615 and a distal end segment 611. The main difference lies in the fact that the anchoring end 14 is here substantially perpendicular to the bridge 615, so that the spike 610, when seen from the side, resembles a twisted "S" ( Figure 14a ), when seen from the front ( Figure 14b ), the spike 610 is contained in a plane of symmetry P.

[0066] Figure 37 and Figure 38The layout of the plurality of spikes 610 in an embodiment of applicator device 5 according to the application is shown. As previously indicated, the spikes 610 of the same row extend from the core 2 in the same way parallel to each other in the same orientation: here, the plane of symmetry P of the spikes 610 is substantially at right angles to the longitudinal axis X. Again, when considering two adjacent rows, the orientation of the spikes 610 of one of the adjacent rows is different from the direction of the spikes 610 of the other of the adjacent rows by 180°, while being longitudinally displaced from one row to the other. Thus, in Figure 38 The front view shown, applicator device 5 according to the application exhibits a series of protrusions (here five protrusions) distributed evenly on the circumference of the core 2.

[0067] Figure 40 Another layout of the plurality of spikes 610 in an embodiment of applicator device 7 according to the application is shown. As previously indicated, the spikes 610 of the same row extend from the core 2 in the same way parallel to each other according to the same orientation: here, the plane of symmetry P of the spikes 610 substantially passes through the longitudinal axis X. Again, when considering two adjacent rows, the orientation of the spikes 610 of one of the adjacent rows is different from the direction of the spikes 610 of the other of the adjacent rows by 180°.

[0068] Figure 41 A similar layout of the plurality of spikes 610 in an embodiment of applicator device 8 according to the application is shown.

[0069] Reference is now made to Figures 16 to Figure 22 A second embodiment of a spike 710 for an applicator device according to the application is described. The spike 710 differs from the previously described spike 10 in that the proximal segment comprises an arcuate shape resulting from two symmetrical curved shapes 713 which are mirror images of each other. Here, each curved shape 713 is similar to the proximal segment 13 of the previously described spike 10. A bridge 715 is located at the junction of the two curved shapes 713, each curved shape 713 forming an anchoring foot extending from the anchoring end 14. The distal segment 11 extends from the bridge 715 to the free end 12.

[0070] In a first variant embodiment shown in Figure 17, the spike 720 comprises a thinner arcuate shape 723 with a flat face 726 contained in the plane of symmetry P. This flat face 726 continues in the bridge 725, thereby providing the latter with a certain flexibility which increases the flexibility of the proximal segment.

[0071] In a second variant embodiment shown in Figure 18, the spike 730 comprises a thinner arcuate shape 723 with a flat face 726 contained in the plane of symmetry P. This flat face 726 continues in the bridge 725, thereby providing the latter with a certain flexibility which increases the flexibility of the proximal segment. Figure 18In the second variant embodiment shown, the spike 730 comprises an arc shape formed by two thinner curved shapes 733 and 734, each of which has a flat face 726 and 736 respectively contained in the plane of symmetry P. This arrangement is such that one of the curved shapes 733 extends on one side of the plane of symmetry P, while the other of the curved shapes 734 extends on the other side of the plane of symmetry P.

[0072] Again, with regard to the bridges 15, 215, 315, according to different variant embodiments, the bridges 715, 725 are positioned on the free end of the curved form of the proximal segment 713, 723, 733, 734 which forms a skirt in a direction which can be parallel to the axis X (that is to say, the bridges 715, 725 are located at the height of the vertex of the curved form of the proximal segment 713, 723, 733, 734), or in a direction which brings it closer to the axis X (the bridges 715, 725 are located at a height lower than the height of the vertex of the curved form of the proximal segment 713, 723, 733, 734), or vice versa, in a direction which brings it further away from the axis X.

[0073] Figure 19 And Figure 20 The layout of a plurality of spikes 710 on an applicator device 3 according to the application is shown. As indicated previously, the spikes 710 on the same row extend from the core 2 in the same way according to the same orientation, parallel to each other. For example, the row comprises spikes 710 from top to bottom, the plane of symmetry P of which is substantially at right angles to the longitudinal axis X. While the spikes 710 of the row adjacent to these two rows are oriented from top to bottom at 90°, their plane of symmetry P substantially passes through the longitudinal axis X of the core 2. Moreover, the spikes 710 are arranged so that, of the three spikes 710 adjacent to each other, one spike in the top row and two spikes from one of the two adjacent rows have the same anchoring foot 713a. In one variant embodiment, this common anchoring foot 713b is shortened so that, in repose, the anchoring foot 713b extends at a distance from the peripheral surface of the core 2 and faces the peripheral surface of the core 2, as shown in Figure 21 In this case, the anchoring foot 713b acts as a bearing abutment so that, during use of the applicator device 3a according to the application, the flexibility of the spike 716 having this common anchoring foot 713b can be adjusted. Figure 22In another such variant embodiment of the applicator device 3b according to the application shown in the middle, the shared anchoring foot 713c is reduced to a simple connection between the spikes 718. The shared anchoring feet 713a, 713b and 713c can be mixed in the same layout with the spikes 710, 716, 717 and 718. This makes it possible to adjust the flexibility of the spikes of the applicator device according to the application.

[0074] Reference is now made to Figure 23 to Figure 26 A third embodiment of a spike for the applicator device 4 according to the application is described. From the anchoring end 14, the spike 1010 comprises a proximal segment 1013, a bridge 1015 and a distal segment 11, 1011 extending to the free end 12. The distal segment here comprises a main extension 11 extending from the bridge 1015 and a secondary extension 1011 extending from the bridge 1015 at a distance along and from the main extension 11. Here, the bridge 1015 forms a flexible connection between the proximal segment 1013 and the distal segments 11, 1011. The secondary extension 1011 forms an angle with the main extension 11 on the symmetry plane P. In Figure 26 In a variant of the spike 1010b shown, the secondary extension 1011b also forms an angle with the symmetry plane P.

[0075] In Figure 23 and 24 Embodiments of a plurality of spikes 1010 and 1010b in an embodiment of the applicator device 4 according to the application are shown. Here, the spikes 1010 form a first longitudinal row, while the spikes 1010b form a second longitudinal row adjacent to the first longitudinal row. Here, the spikes 1010 are oriented in the same direction, their symmetry planes P being at right angles to the longitudinal axis X, and the spikes 1010b are oriented at 90° with respect to the spikes 1010, their symmetry planes P passing through the longitudinal axis X. Other layouts can be derived from those already described with respect to the other embodiments of spikes.

[0076] Fig. 27 and Figure 28 Variants 1110 of the spike 1010 and 1110b of the spike 1010b are shown. These variants comprise a second secondary extension symmetrical to the first previously described, 1011 and 1011b respectively.

[0077] In Figure 29 the variant embodiment 1110c differs from the two previous embodiments, in particular from the spike 1110, in that the main extension 1111 is not tapered, but curved.

[0078] In Figure 30, peg 1210 is a variant embodiment of pegs 1110 and 1110b in which secondary extensions 1011 and 1011b are at 90° to each other. In Figure 31, peg 1310 is a variant embodiment of peg 1210 in which secondary extensions 1011 and 1011b are located on bridge 1015, offset in height: thus, each of secondary extensions 1011, 1011b extends protrudingly from the associated independent flexible bridge 1015.

[0079] Figure 33 shows versions 1410, 1410b of a peg comprising three secondary extensions 1011, 1011b. As such, Figure 34 shows versions 1510, 1510b of a peg comprising four secondary extensions 1011, 1011b. The different secondary extensions can or can not be distributed evenly around primary extension 11.

[0080] Figure 32 shows another variant embodiment of peg 1010. This variant peg 1610 comprises, from anchoring end 14 to free end 12, a proximal segment 1613, a bridge 1615 and distal segments 1611, 1617. This distal segment comprises a primary extension 1611 and a secondary extension 1617 extending from bridge 1615 along and at a distance from primary extension 1611. Furthermore, peg 1610 comprises a first side face 1612 extending along proximal segment 1613, bridge 1615 and primary extension 1611 over the entire height of peg 1610 and located on a circle C. Circle C is in a plane at right angles to longitudinal axis X, the intersection of longitudinal axis X with the plane in which circle C is located being on circle C. This structure of the face of the peg supported by circle C is described in detail in document FR 2 937 514, which can be consulted for more comprehensive information. Moreover, secondary extension 1617 comprises a second side face 1618 facing in the opposite direction to first side face 1612 and located on a circle D.

[0081] Figure 39 Figure 6 shows an applicator device 6 according to the application comprising a layout of a plurality of pegs 1110 and 1510. This layout comprises longitudinal rows of pegs 1510, each of these rows being surrounded on either side by longitudinal adjacent rows comprising pegs 1110.

[0082] Figure 35 shows another variant embodiment of a spike 1710 for an applicator device according to the application. From the anchoring end 14, the spike 1710 comprises a proximal segment 1713, a bridge 1715 and a distal segment 1711, 1717 extending to the free end 12. The distal segment comprises a main extension 1717 extending in unison with the proximal segment 1713 via the bridge 1715. The main extension 1717 comprises an inner flat face 1717a lying in the plane P of the spike 1710. The distal segment further comprises a secondary extension 1711 extending along and at a distance from the main extension 1717. The secondary extension 1711 comprises an inner flat face 1711a not accompanying the plane P and extending facing and at a distance from the plane P.

[0083] Figure 36 shows yet another variant embodiment of a spike 1810 for an applicator device according to the application. From the anchoring end 14, the spike 1810 comprises a proximal segment 1813, a bridge 1815 and a distal segment 1711, 1717 extending to the free end 12. The distal segment comprises a main extension extending in unison with the proximal segment 1813 via the bridge 1815 and having two branches 1717 which are mirror-symmetrical. The branches 1717 comprise an inner flat face 1717a lying in the plane P of the spike 1810. The distal segment further comprises a secondary extension 1711 extending along and at a distance from the main extension. The secondary extension 1711 comprises an inner flat face 1711a not accompanying the plane P and extending facing and at a distance from the plane P.

[0084] The extensions 1717 and / or 1711 extend vertically or straight in the figures, or in a curved manner along a single curve or along several curves.

[0085] So far, the applicator devices according to the application have been described in the form of a main mascara brush or the like. Other forms are also needed for applications to the epidermis (skin, lips).

[0086] With reference to Figures 42 and 43, another embodiment of an applicator device 2020 according to the application is now described. This applicator device 2020 according to the application comprises a hollow core 2000 comprising a tube 2001 comprising a longitudinal slot 2002. The outer surface of the tube 2001 comprises a layout of spikes 2010 which can have the structure of one of the previously described spikes. As shown, this structure of the core 2000 allows it to be unfolded to become flat. This makes it possible to mould such a core comprising complex spikes in the form of its substantially cylindrical tube, allowing the complex spikes to be demoulded, as previously described, or otherwise, which would be difficult or even impossible to do directly in the flat and / or unfolded form of the core. Figure 42b ​

[0087] The applicator device 2020 according to the application also comprises a support 2021 comprising a receiving housing 2023 flanked on either side by a skid 2022. Once the core 2000 has been deployed, it is introduced into the housing 2023 by sliding it along the skids 2022. Finally, the applicator device 2020 according to the application forms a spatula for applying a fluid or pasty product on the skin.

[0088] With reference to Figure 44, a second embodiment of a deployable hollow core 3000 is now described. In this variant embodiment, the core 2000 comprises a tube 3001 comprising longitudinal slots 3002. The outer surface of the tube 3001 comprises a layout of spikes 10 which can have the structure of one of the aforementioned spikes. At one end, the core 3000 comprises a substantially conical nose cone 3003. At the end where the nose cone 3003 is placed, the tube 3001 comprises an inclined cut 3004. This cut will enable the tube 3001 to be deployed without being impeded by the nose cone 3003. Moreover, as illustrated, the core 3000 comprises longitudinal apertures 3005 which pass through the thickness of the tube 3001 and are situated between the longitudinal rows of spikes 10. In a variant embodiment, the core 3000 does not comprise longitudinal apertures.

[0089] With reference to Figure 45, the applicator device 3020 according to the application comprises a support 3021 intended to receive the core 3000 by sliding. This support comprises a main body 3023 in the form of a sabre comprising two longitudinal reservoirs 3022 which are open at the top and are intended to receive the liquid or pasty product to be applied. The main body 3023 terminates in a guard 3024. As illustrated in Figure 45, the deployable hollow core 3000 is slid onto the main body 3023 of the support 3021, the form of which is arranged to cause the tube 3001 to be progressively deployed until the core 3000 is in bearing contact with the guard 3024, the nose cone 3003 receiving the tip of the main body of the support 3021. Once in place, the longitudinal apertures 3005 allow the product stored in the reservoirs 3022 to reach the spikes 10.

[0090] Figure 46 A first variant of the support 3120 is illustrated in which the main body 3123 is solid and does not have reservoirs.

[0091] Figure 47 illustrates a second variant of the support 3220 in which the main body 3223 comprises a recess 3222 which serves as a reservoir for the product once the core 3000 has been placed in position on the support 3220.

[0092] Figure 48 shows a third variant of the support 3320, in which the body 3323 comprises a series of bosses 3322 protruding from the top face, which are covered by the core 3000 once it is in place on the support 3320, the spacing between the bosses 3322 forming product reservoirs. It should be noted that, in addition, these spacings leave "voids" between the top face of the support 3320 and the inner surface of the core 3000. These "voids" thus allow the core 3000 to flex when the makeup is applied, making the application gesture softer and more tactile (comfortable), then the spikes push the core 3000, which slightly "collapses" opposite the spacings of the support 3320.

[0093] Figure 49 A variant embodiment 3420 of one of the aforementioned supports is shown, in which the body 3423 comprises a layout of spikes 10 (which can have the structure of one of the aforementioned spikes) on the face opposite the surface covered by the core 3000 once it is in place.

[0094] Figure 50 to Figure 52 A variant embodiment 3520 of one of the aforementioned supports, in particular the support 3021, is shown. The support 3520 is similar to the support 3021, except that it also comprises a conduit 3025 that passes coaxially through the handle 3026 of the shield 3024 so as to emerge in the longitudinal reservoir 3022 that is open at the top of the body 3023. In Figure 52 In the use shown, the makeup or care product P follows the course indicated by the arrow FP, entering the conduit 3025 through the rear of the handle 3026, then flowing into the reservoir 3022, and exiting by passing through the longitudinal orifice 3005 of the core 3000 placed in position on the support 3520.

[0095] Reference is made to Figure 53 to Figure 56 A variant embodiment 3620 of one of the aforementioned supports, in particular the support 3120, is now described, without being limited thereto. The support 3620 is similar to the support 3120, except that it also comprises a conduit 3125 that passes longitudinally through the support 3620 from the end of the handle 3026 of the shield 3024 to the end 3126 of the body 3123. In Figure 55 or Figure 56 In the use shown, the makeup or care product P follows the course indicated by the arrow FP, entering the conduit 3125 through the rear of the handle 3026, then flowing along the conduit 3125, in the manner of the lead of a mechanical pencil, through the end 3126.

[0096] Here, the support 3620 is mounted with a hollow core 3009, which is a variant embodiment of the aforementioned hollow core 3000, which is adapted to the support 3620 so as to free the output end 3126 of the conduit 3125. Moreover, the support 3620 comprises a face 3624, which is substantially opposite the face of the support 3620 on which the hollow core 3009 is mounted, which has a specific structure: a flocking coating or an additional layer of soft material such as a sponge, a unit or microstructure with the face 3624, or even any layer of soft and microstructured material which has the same effect as the natural use of the tip of the user's finger.

[0097] In Figure 57 and 58 In the variant embodiment of the applicator device according to the application shown in Figure 36, the latter comprises a shaft 3700 mounted on the handle 3026 of the support 3620 and comprises means 3701, 3710 for achieving the flow of the product P, as indicated by the arrow FP. The achieving means 3701 are push buttons 3701 on which a pushing force 3702 causes the flow of the product P. Furthermore, the achieving means 3710 are rings 3710 mounted so as to rotate and arranged so that the rotation 3712 of the rings 3710 causes the flow of the product P. To this end, the push buttons 3701 or the rings 3710 act on a product P dosing system arranged inside the shaft 3700. According to the consistency of the product P used, this dosing system is a pump or a device of the automatic pencil type.

[0098] As can be seen from the above, as mentioned previously, for the applicator device according to the application, this structure of the spike makes it possible to maintain a sufficiently rigid distal section to allow the uncoiling of the keratin fibres when they are guided, the flexible connection formed by the proximal section and / or the bridge acting as a damper so as to be able to eliminate the sensation of pricking when the free end of the spike comes into contact with the underlying skin. Moreover, the deformation obtained in use at the bottom of the spike makes it possible for the product present at this tip to rise to the free end of the spike.

[0099] Finally, the applicator device according to the application makes it possible to improve the management of the cosmetic or care product and its application on the keratin fibres (while ensuring their optimal separation) or the epidermis, while providing optimal comfort for its user.

[0100] Obviously, many modifications can be made to the application without, in any way, departing from the scope thereof.
