Description

[Technical field]

[0001] The present invention relates to the field of applicators for applying cosmetic products to the skin, in particular for applying make-up products to the eyes, and in particular for applying eyeliner to the eyelids. [Background technology]

[0002] It is known practice in the art to make applicators in the form of a pencil, the lead of which forms the application member that enables a line of eyeliner to be drawn on the eyelid at the base of the eyelashes and / or a flick to be drawn at the outer corner of the eye.

[0003] Applicators in the form of pens are also known in the art, the body of which is hollow and which forms a product reservoir which communicates with an application member in the form of a tip made of a porous material, generally felt, into which the product is delivered by capillary action, enabling a line of eyeliner to be drawn on the eyelid at the base of the eyelashes and / or a flick to be drawn on the outer corner of the eye.

[0004] There also exist applicators in the field in the form of dip applicators, which comprise a handling element, a handle and an application member carried at the end of the handle and intended to be dipped into a container containing the product to be applied in order to load it with the product and to enable a line of eyeliner to be drawn on the eyelid at the base of the eyelashes and / or a flick on the outer corner of the eye.

[0005] However, the use of such eyeliner applicators by drawing, where the application member is placed in contact with the eyelid and drawn parallel to the lash line to draw a line of eyeliner, requires a certain amount of practice and a certain dexterity to draw a sharp, continuous and precise line of eyeliner on the eyelid.

[0006] Additionally, especially for older users, the drawing action associated with an eyeliner applicator can cause a certain amount of deformation of the eyelid as the application member passes over the eyelid, which tends to produce irregular lines and accentuate fine lines on the eyelid.

[0007] Therefore, to overcome these drawbacks, applicators have been developed that include a member for applying a cosmetic product by stamping it onto the skin, in which the application member has an application surface suitable for being placed at least partially in contact with the skin for loading the cosmetic product by placing the application surface in contact with the cosmetic product, and for depositing on the skin by stamping a line or imprint of the cosmetic product, the shape and contour of which substantially corresponds to the shape and contour of the portion of the application surface that is placed in contact with the skin.

[0008] Such applicators facilitate the act of applying cosmetic products, and in particular eyeliner, to the eyelid, since the stamping action is easier for an inexperienced user to control than when a line of eyeliner is drawn using an application member that is slid along the eyelid.

[0009] Furthermore, with such stamp applicators, the eyelids are not deformed during application of the eyeliner, and therefore the eyeliner line is thus formed more clearly and precisely, especially for older users whose eyelids tend to be easily deformed or folded as the applicator member slides over them.

[0010] Patent document 1 in the name of the present applicant describes such a stamp applicator, in which the application member is provided at the end of a handle and is in the form of a spatula, one teardrop-shaped surface of which is adapted to enable stamp application of a line of eyeliner forming a flick at the corner of the eye.

[0011] However, such applicators can only create a flick on a user's eyelid at the outer corner of the eye, and the application member is not suitable for creating a line of eyeliner on the eyelid at the base of the eyelashes.

[0012] US Patent No. 5,399,943 similarly describes a stamp applicator in which the application member received at the end of a handle has a generally triangular shape and is intended only for flick stamp application at the outer corner of the eye and is not suitable for forming a line of eyeliner on the eyelid at the base of the eyelashes. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] French Patent No. 3026620 [Patent Document 2] U.S. Patent No. 9,635,924 Summary of the Invention [Means for solving the problem]

[0014] The present invention is directed to overcoming these drawbacks and, to this end, proposes an application member for applying a cosmetic product by stamping it on the skin, in particular for applying an eyeliner to the eyelids, defining a longitudinal axis, a transverse axis perpendicular to the longitudinal axis and a front-to-back axis perpendicular to the longitudinal and transverse axes, having a pre-application surface suitable for being placed at least partially in contact with the skin for loading the cosmetic product by placing the pre-application surface in contact with the cosmetic product and for depositing on the skin by stamping a line or trace of the cosmetic product, the shape and contour of which substantially correspond to the shape and contour of the portion of the pre-application surface placed in contact with the skin, the pre-application surface having an elongated shape along the transverse axis and which is outwardly convex when the application member is viewed in the plane defined by the longitudinal and transverse axes.

[0015] These conditions allow the application of a line of eyeliner to the eyelid, the shape and contour of which corresponds to that of the part of the front application surface placed in contact with the skin, to be carried out easily and ergonomically for inexperienced users and in a precise manner for older users, by placing at least a part of the front application surface in contact with the eyelid at the root of the eyelashes, with the transverse axis of the application member extending substantially parallel to the eyelash line and, in particular, with the longitudinal axis of the application member extending substantially perpendicular to the eyelid.

[0016] A user may adopt different gestures to apply cosmetic product with a stamp using an application member according to the present invention.

[0017] According to a first gesture of use, the user loads the entire pre-application surface with cosmetic product and places substantially the entire pre-application surface in contact with the skin to deposit on the skin by stamping a line of cosmetic product, the line of cosmetic product having a shape and contour substantially corresponding to the shape and contour of the pre-application surface.

[0018] Thus, application of a line of eyeliner to the eyelid, the shape and contour of which substantially corresponds to that of the pre-application surface, is achieved by placing the product-loaded pre-application surface in contact with the eyelid at the base of the eyelashes, with the transverse axis of the applicator member extending substantially parallel to the line of implantation of the eyelashes and preferably with the longitudinal axis of the applicator member extending substantially perpendicular to the eyelid, and by rolling the pre-application surface over the eyelid by rotation of the applicator member about its anterior-posterior axis, alternately in first and second rotational directions.

[0019] The outwardly convex shape of the pre-application surface when the applicator member is viewed in a plane defined by the longitudinal and transverse axes advantageously facilitates this rolling movement of the pre-application surface on the eyelid upon rotation of the applicator member about the anterior-posterior axis.

[0020] According to a second gesture of use, the user loads all or a portion of the pre-application surface with cosmetic product and places only the product-loaded portion of the pre-application surface, for example a central portion or a side portion, particularly a side half, of the pre-application surface in contact with the skin in order to deposit on the skin a line of cosmetic product by stamping the line of cosmetic product, the shape and contour of which substantially corresponds to the shape and contour of the portion of the pre-application surface that has been brought into contact with the skin.

[0021] Thus, application of a line of eyeliner to the eyelid, the shape and contour of which substantially corresponds to that of the portion of the front application surface placed in contact with the skin, is achieved by placing the product-loaded portion of the front application surface in contact with the eyelid at the base of the eyelashes, preferably without rolling the front application surface over the eyelid, with the transverse axis of the applicator member extending substantially parallel to the line of implantation of the eyelashes and in particular with the longitudinal axis of the applicator member extending substantially perpendicular to the eyelid.

[0022] Where the dimensions of the applicator member are such that application of a full line of eyeliner on the eyelid at the base of the lashes requires several adjacent successive applications to achieve application of the full line of eyeliner, the line extending from the outer corner to the inner corner of the eye, the first gesture may advantageously allow the user to achieve application of the full line of eyeliner with fewer successive applications than the second gesture, however this first gesture requires rolling of the front application surface on the eyelid by rotation of the applicator member about a front-to-back axis, which may be cumbersome for some users who prefer to employ the second gesture even though it requires a greater number of successive applications to form a full line of eyeliner at the base of the lashes.

[0023] The application member according to the invention may be in the form of a handle which can be handled by a user, in particular a tip which can be connected to the end of the handle.

[0024] The application member according to the invention is advantageously used at the end of a handle which can be used by a user, and therefore has along its longitudinal axis an end for attachment to the handle and an opposite application end carrying a front application surface.

[0025] The term "elongated shape along the transverse axis" with respect to the pre-applied surface should be understood to mean that the pre-applied surface has a greater dimension along the transverse axis than along the front-to-rear axis or along the longitudinal axis.

[0026] Such an elongated shape of the pre-application surface makes it possible to stamp onto the skin a line, the shape and contour of which corresponds to the shape and contour of the portion of the pre-application surface that is placed in contact with the skin, thus forming an elongated line on the eyelid at the base of the eyelashes.

[0027] Furthermore, the term "a pre-application surface which is outwardly convex when the applicator member is viewed in the plane defined by the longitudinal and transverse axes" should be understood to mean that the intersection between the pre-application surface and any plane parallel to it defined by the longitudinal and transverse axes is a curved segment, in particular a circular segment, which is convex towards the exterior of the applicator member.

[0028] The outwardly convex profile of the pre-application surface in the plane defined by the longitudinal and transverse axes makes it possible to easily and accurately stamp and apply a line of eyeliner to the root of the eyelashes, in the domed portion of the eyelid as well as in the recessed portions of the eyelid located in the inner and outer corner areas.

[0029] Furthermore, this outwardly convex profile of the pre-application surface encourages a rolling movement of the pre-application surface on the eyelid upon rotation of the applicator member about the anterior-posterior axis within the frame of the first gesture of use identified above.

[0030] According to a particularly advantageous condition of the invention, when the applicator member is viewed in a plane defined by the transverse axis and the longitudinal axis, the front application surface has a curved contour defining a concave surface.

[0031] The term "pre-application surface having a curved contour defining a concave surface when the application member is viewed in a plane defined by the transverse axis and the longitudinal axis" should be understood as meaning that the intersection between the pre-application surface and any plane parallel to it defined by the transverse axis and the longitudinal axis, or a cross-section of the pre-application surface in a plane parallel to it defined by the transverse axis and the longitudinal axis, has a curved extension, in particular a bean-shaped curved closed contour extending along the axis of a circular arc.

[0032] The curved profile of the pre-application surface in the plane defined by the transverse and anterior-posterior axes can further improve the ease, ergonomics and precision of stamping a line of eyeliner at the base of the lashes, with the concave surface defined by the curved profile conforming to the curvature of the lash line so that the applied eyeliner line follows the lash line as closely as possible.

[0033] According to other advantageous aspects, the applicator according to the invention comprises one or more of the following characteristics, either separately or in all technically possible combinations, namely: - the front application surface has a circular profile when the applicator member is viewed in the plane defined by the longitudinal and transverse axes, said circular profile having a radius of curvature preferably less than 60 mm, in particular between 30 mm and 50 mm, in particular about 40 mm. According to these conditions, the curvature of the front application surface in the plane defined by the longitudinal and transverse axes is particularly well suited for a sharp and precise application of the eyeliner in the concave parts of the eyelid located in the inner and outer corner regions as well as in the domed parts of the eyelid. Moreover, such a curvature of the front application surface in the plane defined by the longitudinal and transverse axes facilitates a rolling movement of the front application surface on the eyelid by rotation of the applicator member about the anterior-posterior axis within the frame of the first gesture of use as revealed above. - the curved contour of the pre-application surface in the plane defined by the transverse and anteroposterior axes extends along a curved axis, said curved axis advantageously forming a circular arc with a radius of curvature preferably between 30 mm and 200 mm, in particular about 50 mm. According to these conditions, the curvature of the pre-application surface in the plane defined by the transverse and anteroposterior axes is particularly well suited to further improve the ease, ergonomics and precision of the stamp application of the eyeliner line at the root of the eyelashes, the concavity defined by this curved contour being adapted to the curvature of the eyelash line in such a way that the applied eyeliner line follows this eyelash line as closely as possible. - the front application surface is substantially flat when the applicator member is seen in the plane defined by the longitudinal and anteroposterior axes. In other words, the intersection between the front application surface and any plane defined by the longitudinal and anteroposterior axes and parallel thereto is a substantially straight line segment. Thanks to these conditions, an applicator member is provided which ensures a particular comfort of application, the application surface being free of any unpleasant and even potentially harmful edges when placed in contact with the skin in the plane defined by the longitudinal and anteroposterior axes, and at the same time ensuring a controlled, constant and relatively precise width of the cosmetic product on the skin, in particular of the eyeliner line applied to the eyelid. - the front application surface extends over a height along the longitudinal axis and has a width measured along the transverse axis between a first lateral end and an opposite second lateral end, a thickness measured along the longitudinal axis between the first edge and the opposite second edge, and a thickness of the front application surface which varies when moving along the transverse axis and is a minimum at the first lateral end and / or at the second lateral end. According to these conditions, a stamp application member is obtained, the front application surface of which narrows in the direction of one or both of its lateral ends, which makes it possible to apply a line of eyeliner with the narrowed end on the eyelid, in particular on the ends of the eyelid located in the inner and outer corner regions, which contributes to the aesthetic appeal of the resulting make-up. Furthermore, due to the shape of the pre-application surface of the application member, which is thinned at the lateral ends, it is possible to apply a curved line of eyeliner that follows the curvature of the eyelid at the base of the eyelashes, formed from a plurality of adjacent lines superimposed by stamping with the application member, with an angular shift about the longitudinal axis between the adjacent lines, in order to form a substantially continuous contour, i.e. a contour with substantially no recesses / sharp angles, in particular at the junction between two adjacent lines. As a variant, the thickness of the pre-application surface is substantially constant when moving along the transverse axis. In particular, when the pre-application surface has a curved contour in the plane defined by the transverse axis and the longitudinal axis, said contour extends along a curved axis forming a circular arc, and the thickness of the pre-application surface is substantially constant when moving along this curved axis. According to these conditions, the line of cosmetic product applied to the skin by the pre-application surface will correspondingly have a substantially constant thickness over its entire length. This constant thickness of the pre-applied surface when viewed in the plane defined by the transverse and anterior-posterior axes, combined with the curved contour of the pre-applied surface in this same plane, advantageously makes it possible to apply a curved line of eyeliner that follows the curvature of the eyelid at the base of the eyelashes, formed from a plurality of adjacent lines that are layered by stamping using an application member, with an angular shift about the longitudinal axis between adjacent lines to form a substantially continuous contour, i.e. a contour that has substantially no recesses / distinct angles, especially at the junction between two adjacent lines. - the thickness of the pre-application surface is minimal, in particular zero, at the first lateral end and / or at the second lateral end, and the first and second edges of the pre-application surface meet at the first lateral end and / or at the second lateral end. Thanks to these conditions, an applicator member for creating an eyeliner line on the eyelid, the ends of which are located at the inner and outer corners of the eye, are provided that are precise and aesthetic. - the thickness of the front application surface varies continuously when moving along the transverse axis, said front application surface having a substantially oval, in particular elliptical, shape when projected in a plane perpendicular to the longitudinal axis. As a variant, the first and second edges of the front application surface meet at the first and / or second lateral ends to form a rounded shape, said front application surface having a curved, substantially oblong, shape when projected in the plane defined by the transverse and anterior-posterior axes. Such a shape is particularly suitable for making it possible to form adjacent lines of eyeliner on the eyelid, successively stacked by partially overlapping at their ends, in order to form continuous lines of eyeliner over the entire length of the eyelid together on the eyelid by adapting to the topology of the eyelid, in particular curved lines. Such a shape in particular allows for the application of a curved line of eyeliner that follows the curvature of the eyelid at the base of the eyelashes, formed from a plurality of adjacent lines that are layered by stamping with an application member, with an angular shift about the longitudinal axis between the adjacent lines to form a contour of substantially continuous curvature, i.e. a contour that has substantially no recess / distinct angles, in particular at the junction between two adjacent lines. The maximum thickness of the pre-coated surface, preferably midway between the first and second lateral ends of the pre-coated surface, is between 0.5 mm and 2.5 mm, preferably about 1.3 mm. The width of the pre-applied surface is advantageously between 10 and 20, in particular about 15 mm. - the first and / or second edge of the pre-application surface has, in particular at the first and / or second side end, a rim protruding from the pre-application surface along the longitudinal axis. Such a protruding rim advantageously makes it possible to create a reserve of cosmetic product between the pre-application surface and said protruding rim, thus increasing the amount of cosmetic product that the application member can carry and improving its autonomy and reducing the frequency with which the user must load it with product.

[0034] According to advantageous conditions, the application member also has an application side surface adjacent to the front application surface and extending substantially perpendicularly therefrom, said application side surface being preferably outwardly concave when the application member is viewed in a plane defined by the longitudinal axis and the transverse axis.

[0035] Such an implementation of the application side surface or application flank which forms an acute angle with the previous application surface is particularly advantageous for limiting the risk of contamination between the product traces deposited by the previous application surface and the product traces deposited by the application side surface.

[0036] Moreover, when the application member according to the invention is attached to a handle, in particular with the longitudinal axis of the handle coinciding with the longitudinal axis of the applicator member, such an implementation of the application side surface is particularly convenient in terms of the ergonomics of use, in particular for the build-up of product, in particular eyeliner traces, at the inner corner of the eye, while avoiding the handle hitting the bridge of the nose, as may occur if application of the product at the inner corner of the eye is achieved by means of the front application surface. Indeed, in such a case, when applying a trace of eyeliner at the inner corner of the eye by means of the application side surface, the handle is placed with its longitudinal axis extending substantially parallel to the eyelid, so that the risk of hitting the bridge of the nose during this application is limited.

[0037] The term "an application side which is outwardly concave when the application member is viewed in the plane defined by the longitudinal and transverse axes" should be understood to mean that the intersection between the application side and any plane parallel to it defined by the longitudinal and transverse axes is a curved segment, in particular a circular segment, which is concave towards the exterior of the application member.

[0038] The outwardly concave profile of the application side in the plane defined by the longitudinal and transverse axes allows for easy and precise application, by stamping, of a line of eyeliner at the base of the eyelashes, particularly in the recessed portions of the eyelid located in the inner and outer corner areas.

[0039] Preferably, the application side has a circular profile when the application member is viewed in the plane defined by the longitudinal and transverse axes, said circular profile preferably having a radius of curvature of 140 mm to 170 mm, in particular about 155 mm. According to these conditions, the curvature of the application side in the plane defined by the longitudinal and transverse axes is particularly well suited for a sharp and precise application of a line of eyeliner in the concave parts of the eyelid, in particular located in the area of ​​the inner and outer corners of the eye.

[0040] Alternatively, the application side surface is flat or outwardly convex when the applicator member is viewed in the plane defined by the longitudinal and transverse axes.

[0041] According to advantageous conditions of the invention, the applicator side has a notch in the plane defined by the longitudinal axis and the transverse axis. In the implementation of this notch, preferably on each applicator side, the height of the applicator member along the longitudinal axis is reduced at that side compared to the height of its central part. These sides of the applicator member which have a notch perpendicular thereto are therefore more flexible than the central part of the applicator member, in particular in the direction of the longitudinal axis and the anterior-posterior axis. These conditions are particularly advantageous for applying curved lines of eyeliner which follow the curvature of the eyelid at the base of the eyelashes, formed from a number of adjacent lines superimposed by stamping with the applicator member, the flexibility of the sides of the applicator member allowing the user to correct the deformation of the applicator member, in particular to obtain a substantially continuous contour at the junction between two adjacent lines, i.e. a contour with substantially no recesses / sharp angles.

[0042] In one embodiment of the invention it may be envisaged that at least the pre-application surface of the application member carries a flocking, such flocking being in particular capable of increasing the autonomy of the application member.

[0043] The present invention relates to an applicator for applying a cosmetic product by stamping it onto the skin, in particular for applying eyeliner to the eyelids, comprising: - a handle extending along a longitudinal axis between a first end and an opposing second end; - an application member attached to a first end of a handle as defined above, said longitudinal axis of the handle preferably coinciding with the longitudinal axis of the application member; The present invention also covers an applicator including:

[0044] As a variant, the longitudinal axis of the handle may be parallel to the longitudinal axis of the application member or may form an angle with it.

[0045] Advantageously, the cross-section of the handle in the plane defined by the transverse axis and the longitudinal axis has a curved contour defining a concave surface, said concave surface preferably having the same orientation as the concave surface defined by the curved contour of the pre-application surface in the plane defined by the transverse axis and the longitudinal axis.

[0046] Preferably, the curved contour of the front application surface belonging to the application member in the plane defined by the transverse axis and the longitudinal axis and / or the curved contour of the cross-sectional view of the handle in this same plane is symmetrical with respect to the plane defined by the longitudinal axis and the longitudinal axis.

[0047] According to these conditions, both the handle and the application member of the applicator according to the invention have a concave shape with the same orientation along the longitudinal axis in the plane defined by the transverse axis and the anterior-posterior axis, so that the user intuitively and ergonomically decides how to hold the applicator in order to orient the concave surface of the front application surface of the application member appropriately relative to her eyelid, i.e. in the direction of the eye to be made up.

[0048] Preferably, the curved profile of the cross-section of the handle in the plane defined by the transverse axis and the longitudinal axis extends along a curved axis, said curved axis advantageously forming a circular arc having a radius of curvature preferably between 10 mm and 35 mm, in particular about 15 mm.

[0049] The curvature of the handle in the plane defined by the transverse and anteroposterior axes may therefore be more pronounced than the curvature of the pre-application surface in this same plane. In other words, the radius of curvature of the handle in the plane defined by the transverse and anteroposterior axes may therefore be smaller than the radius of curvature of the pre-application surface in this same plane. This is particularly advantageous insofar as the curvature of the pre-application surface is adapted to the curvature of the lash line, which may be relatively small (relatively large radius of curvature) for the user and may be difficult for the user to find in order for her to hold and operate the applicator in the proper orientation. The more pronounced curvature of the handle in the plane defined by the transverse and anteroposterior axes more clearly indicates to the user the proper orientation for handling and operating the applicator.

[0050] According to advantageous conditions, the second end of the handle is provided with an auxiliary application member having an application surface suitable for being placed in contact with the skin for loading the cosmetic product by placing the auxiliary application surface in contact with the cosmetic product and for depositing thereon a line of cosmetic product by stamping a line the shape and contour of which substantially corresponds to the shape and contour of the auxiliary application surface, the auxiliary application surface in particular extending in a plane forming an angle with the longitudinal axis of the handle and preferably having a triangular or teardrop-shaped outer contour.

[0051] An applicator is thus obtained which makes it possible to simultaneously apply, by stamping, a line of eyeliner along the eyelid at the base of the eyelashes and a flick of eyeliner in the form of a triangle or drop at the outer corner of the eye.

[0052] In one embodiment of the invention, it can be envisaged that at least the auxiliary application surface of the auxiliary application member carries a flocking. Such a flocking makes it possible in particular to increase the autonomy of the auxiliary application member.

[0053] According to a preferred embodiment of the invention, the application member and / or the auxiliary application member are attached to the first and / or second end of the handle by overmolding, such a provision making it possible to simplify the manufacture of the applicator and to reduce its costs, and also to facilitate its use in the form of a single object.

[0054] To this end, the first and second ends of the handle advantageously have protrusions defining hollow portions that facilitate attachment of the application member and / or auxiliary application member to the handle by overmolding.

[0055] As a variant, the application member and / or the auxiliary application member are co-injected with the handle.

[0056] Preferably, the handle is made of a relatively rigid plastic, in particular a thermoplastic material, such as polypropylene (PP), polyethylene (PE), polyamide (PA), etc. Such a relatively rigid plastic may for example have a Shore hardness of greater than 80 Shore D.

[0057] Preferably, the application member and / or the auxiliary application member are made of a relatively flexible plastic, such as silicone, rubber or a thermoplastic elastomer (TPE). Such a relatively flexible plastic may have a Shore hardness of, for example, 20 Shore A to 80 Shore D.

[0058] The term "relatively rigid" should be understood to mean that the plastic from which the handle is made is more rigid than the plastic from which the application member and / or auxiliary application member are made. Similarly, the term "relatively flexible" should be understood to mean that the plastic from which the application member and / or auxiliary application member are made is more flexible than the plastic from which the handle is made.

[0059] Advantageously, the material making the handle and the material making the applicator member have a difference in hardness of at least 10 Shore units, even better at least 20 Shore units.

[0060] The invention also relates to an assembly for packaging and stamp application of a cosmetic product, in particular an eyeliner, comprising: - a container containing the cosmetic product to be applied, - the applicator previously described; The present invention relates to an assembly including:

[0061] According to another aspect of the invention, there is provided a method for applying a cosmetic product to the skin, in particular for applying eyeliner to the eyelids, comprising the steps of: - providing a packaging and application assembly as described above; - loading the cosmetic product to be applied onto at least a portion of the pre-application surface by placing said portion of the pre-application surface in contact with the cosmetic product contained in the container; - applying the cosmetic product loaded on the pre-application surface by placing it in contact with the skin in order to deposit a line of cosmetic product on the skin by stamping the line, the shape and contour of which substantially corresponds to the shape and contour of the portion of the pre-application surface placed in contact with the skin, the longitudinal axis of the application member being preferably arranged substantially perpendicular to the surface of the skin and, where appropriate, the concave surface of the pre-application surface being oriented towards the eye; A method is proposed comprising the steps:

[0062] According to advantageous conditions, the method according to the invention comprises a number of successive steps of applying the cosmetic product loaded on the pre-application surface to the skin, the lines of cosmetic product successively layered on the skin being adjacent to each other and preferably partially overlapping, so as to together form a continuous line of cosmetic product on the skin, in particular a continuous curved line.

[0063] Due to the shape of the front application surface of the application member, which is thinner at the lateral ends, it is possible to apply a curved line of eyeliner that follows the curvature of the eyelid at the base of the eyelashes, formed from a number of adjacent lines that are layered by stamping with the application member, with an angular shift about the longitudinal axis between the adjacent lines to form a contour of substantially continuous curvature, i.e. a contour that has substantially no recesses / distinct angles, especially at the junction between two adjacent lines.

[0064] Advantageously, two adjacent lines of cosmetic product successively deposited on the skin overlap over a length of between 0.5 mm and 5 mm, preferably between 1 and 3 mm, in particular about 2 mm.

[0065] When using an application member comprising an application side as described above, the method according to the invention advantageously comprises the following additional steps: - loading the cosmetic product to be applied onto the application side by placing the application side in contact with the cosmetic product contained in the container; - applying the cosmetic product loaded on the application side to the skin, in particular at the inner corner of the eyelid, by placing it in contact with the skin in order to deposit on the skin a line of cosmetic product, the shape and contour of which substantially corresponds to the shape and contour of the application side, the longitudinal axis of the application member being preferably arranged substantially parallel to the surface of the skin, in particular such that said line deposited by the application side is adjacent to and partially overlaps the line of cosmetic product deposited by the previous application side; Includes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0070] 1 to 4 show an applicator 1 for stamp application of a cosmetic product P to the skin, in particular for application of an eyeliner to the eyelids, in a first embodiment, using an applicator member according to a first embodiment of the invention.

[0071] As can be seen in FIGS. 1-3, the applicator 1 includes a handle 2 extending along a longitudinal axis X′ between a first end 21 and an opposing second end 22 .

[0072] As will be seen in more detail herein below, a first end 21 of the handle 2 is provided with an application member 3 or primary application member and a second end 22 of the handle 2 is provided with an auxiliary application member 4 .

[0073] The main application member 3 is in the form of a tip connected to a first end 21 of the handle 2 that can be handled by a user.

[0074] The main application member 3, provided for stamp application of a cosmetic product P to the skin, in particular for application of eyeliner to the eyelids, defines a longitudinal axis X, a transverse axis Y perpendicular to the longitudinal axis X, and a front-to-back axis Z perpendicular to the longitudinal axis X and the transverse axis Y.

[0075] In the embodiment shown, the longitudinal axis X of the main application member 3 coincides with the longitudinal axis X′ of the handle 2 when the application member 3 is attached to the first end 21 of the handle 2 .

[0076] In a variant not shown, the longitudinal axis X of the application member 3 may be parallel to the longitudinal axis X' of the handle 2 or form an angle with the longitudinal axis X of the handle 2 when the application member 3 is attached to the first end 21 of the handle 2, and an offset or displaced arm may, for example, connect the application member 3 to the first end 21 of the handle 2.

[0077] As can be seen in Figures 1 to 4, the main application member 3 has a pre-application surface 30 suitable for being placed at least partially in contact with the skin, in the present case the eyelid, and in particular the roots of the eyelashes, for loading the cosmetic product P, in the present case an eyeliner composition, to be applied by placing the pre-application surface 30 in contact with the cosmetic product P, and for depositing on the skin by stamping a line of product P, the shape and contour of which substantially corresponds to the shape and contour of the portion of the pre-application surface 30 placed in contact with the skin.

[0078] The main application member 3 has, along a longitudinal axis X, a first end 37 constituting an end for attachment to the handle 2 and an opposite second end 38 carrying the front application surface 30 .

[0079] According to the invention, and as is particularly apparent in Figures 3 and 4, the front application surface 30 has an elongated shape along the transverse axis Y, which is outwardly convex when the application member 3 is viewed in the plane defined by the longitudinal axis X and the transverse axis Y.

[0080] The term "elongated along transverse axis Y" should be understood to mean that the pre-applied surface has a greater dimension along this transverse axis Y, and that its dimensions along the longitudinal axis X and along the longitudinal axis Z are less than the dimensions along the transverse axis Y.

[0081] Furthermore, and as can be seen more particularly in FIG. 3 , the pre-application surface 30 advantageously has a circular profile, in other words the pre-application surface 30 extends along a circular arc when the main application member 3 is viewed in the plane defined by the longitudinal axis X and the transverse axis Y, i.e. in the plane X, Y.

[0082] Thus, the term "a pre-application surface 30 which is outwardly convex when the applicator member is viewed in the plane defined by the longitudinal axis X and the transverse axis Y" should be understood as meaning that the intersection between the pre-application surface 30 and any plane parallel to it defined by the longitudinal axis X and the transverse axis Y is a curved segment, in particular a circular segment, which is convex towards the outside of the main applicator member 3.

[0083] Advantageously, the circular profile of the front application surface 30 in the plane X, Y has a radius of curvature of less than or equal to 60 mm, in particular between 30 mm and 50 mm, in particular about 40 mm. Such a curvature is particularly advantageous for making it possible to easily and accurately apply a line of eyeliner composition not only to the domed part of the eyelid, but also to the concave parts of the eyelid at the edge of the eyelid, in particular in the inner and outer corner regions.

[0084] 1-4, the pre-application surface 30 is substantially flat when the main application member 3 is viewed in the plane defined by the longitudinal axis X and the front-to-rear axis Z, i.e. in plane X, Z. In other words, the intersection between the pre-application surface 30 and any plane parallel to planes X, Z is a substantially straight line segment.

[0085] As a variant, it can be envisaged that the pre-application surface 30 is outwardly convex when the main application member 3 is viewed in the plane defined by the longitudinal axis X and the longitudinal axis Z, i.e. in the plane X, Z. In this variant, the intersection between the pre-application surface 30 and any plane parallel to the planes X, Z is therefore a substantially curved segment, in particular a circular segment.

[0086] In particular, as can be seen in Figures 3 and 4, the pre-application surface 30 extends for a height h along a longitudinal axis X between its first end 37 for attachment to a handle and its second end 38 which carries the pre-application surface 30.

[0087] Pre-coat surface 30 further has a width l measured along transverse axis Y between first lateral end 31 and opposite second lateral end 32 .

[0088] The width l of the pre-application surface 30 is advantageously between 10 mm and 20 mm, in particular about 15 mm.

[0089] Finally, the pre-coat surface 30 has a thickness measured along a front-to-rear axis between a first edge 33 and an opposing second edge 34 .

[0090] According to an advantageous condition of the invention, the thickness e of the pre-application surface 30 varies when moving along the transverse axis Y and is a minimum at the first lateral end 31 and at the second lateral end 32 .

[0091] Thus, a main stamp application member 3 is obtained, the front application surface 30 of which narrows in the direction of its lateral ends 31, 32, making it possible to apply a line of eyeliner with a narrower edge to the eyelid, in particular to the edge of the eyelid located in the inner and outer corner region, which contributes to the aesthetic appeal of the resulting makeup.

[0092] Furthermore, as will be presented in more detail in the remaining part of the description of the invention, the shape of the front application surface 30 of the main application member 3, which is thinner at the lateral ends 31, 32, makes it possible to apply a curved line of eyeliner that follows the curvature of the eyelid at the root of the eyelashes, formed from a plurality of adjacent lines that are stacked by stamping using the application member 3, with an angular shift about the longitudinal axis X between the adjacent lines to form a contour of substantially continuous curvature, i.e. a contour that has substantially no recesses / distinct angles, especially at the junction between two adjacent lines.

[0093] More specifically, in the illustrated embodiment, the thickness e of the pre-coated surface 30 is zero at the first and second side ends 31, 32, and the first and second edges 33, 34 of the pre-coated surface 30 meet at these first and second side ends 31, 32.

[0094] Even more specifically, in the embodiment shown in Figures 1 to 11, and as can be seen in particular in Figure 4, the thickness e of the pre-application surface 30 varies continuously when moving along the transverse axis Y, said pre-application surface 30 having, projected in a plane perpendicular to the longitudinal axis X, a substantially elliptical shape, in particular an elliptical shape.

[0095] The maximum thickness of the pre-coated surface, in the illustrated embodiment, is halfway between the first and second ends 31, 32 of the pre-coated surface 30 and is between 0.5 mm and 2.5 mm, preferably about 1.3 mm.

[0096] According to an advantageous condition of the invention, the pre-application surface 30 of the main application member 3 is laterally elongated by application sides 35 , 36 which extend substantially perpendicularly to the pre-application surface 30 .

[0097] In the manner of the pre-application surface 30, the application sides 35, 36 are suitable for loading the cosmetic product P by placing the application sides 35, 36 in contact with the cosmetic product P, and for placing the application sides 35, 36 in contact with the skin for depositing a line of the cosmetic product P on the skin by stamping a line of the cosmetic product P whose shape and contour substantially correspond to the shape and contour of the application sides 35, 36.

[0098] Advantageously, the application sides 35, 36 are outwardly concave when the application member is viewed in the plane X,Y.

[0099] The term "outwardly concave when the application member is viewed in the plane X, Y" should be understood to mean that the intersection between the application sides 35, 36 and any plane parallel to the plane X, Y is a curved segment, in particular a circular segment, that is concave towards the outside of the main application member 3.

[0100] As will be explained herein below, the outwardly concave profile of the application sides 35, 36 in planes X, Y allows for easy and precise stamping to apply a line of eyeliner to the base of the eyelashes, particularly in the recessed portions of the eyelid located in the inner and outer corner areas.

[0101] Preferably, the application sides 35, 36 have a circular profile when the main application member 3 is viewed in the plane X, Y, said circular profile preferably having a radius of curvature between 140 mm and 170 mm, in particular about 155 mm. Due to these conditions, the curvature of the application sides 35, 36 in the plane X, Y is particularly well suited for a sharp and precise application of a line of eyeliner in the hollow parts of the eyelid, in particular located in the area of ​​the inner and outer corners of the eye.

[0102] 6 and 7 show an applicator for stamp application of a cosmetic product using an application member according to a second embodiment of the invention. This second embodiment of the invention differs from the first in that the application sides 35, 36 have a larger dimension along the longitudinal axis X.

[0103] Thus, in the first embodiment, the main application member 3 has a height along the longitudinal axis X of 3 mm to 6 mm, for example about 4.5 mm, and in the second embodiment, the main application member 3 has a height h along the longitudinal axis X of 10 mm to 20 mm, for example about 15 mm.

[0104] Furthermore, as can be seen particularly in FIGS. 1-3, the second end 22 of the handle 2 is provided with an auxiliary application member 4 .

[0105] The auxiliary application member 4 has an auxiliary application surface 40 suitable for loading the cosmetic product P by placing the auxiliary application surface 40 in contact with the cosmetic product P, and for placing it in contact with the skin for laminating it onto the skin by stamping a line ts of the cosmetic product P, the shape and contour of which substantially corresponds to the shape and contour of the auxiliary application surface 40.

[0106] The auxiliary application surface 40 extends in a plane which forms an angle with the longitudinal axis X' of the handle 2 and has a triangular or teardrop-shaped outer contour.

[0107] This auxiliary application member 4 enables stamp application of eyeliner to the outer corner of the eye.

[0108] An applicator 1 is thus obtained, which allows both the stamp application of a line of eyeliner along the eyelid at the base of the eyelashes using the front application surface 30 and application sides 35, 36 belonging to the main application member 3, and the stamp application of a flick of eyeliner to the outer corner of the eye using the auxiliary application surface 40 belonging to the auxiliary application member 4.

[0109] Preferably, the handle 2 and the main and auxiliary application members 3, 4 of the applicator are made of plastic.

[0110] More precisely, the handle 2 is advantageously made of a relatively rigid plastic, in particular a thermoplastic material, such as polypropylene (PP), polyethylene (PE), polyamide (PA), etc. Such a relatively rigid plastic may for example have a Shore hardness greater than 80 Shore D.

[0111] Furthermore, the main application member 3 and the auxiliary application member 4 are made of a relatively flexible plastic, such as silicone, rubber or a thermoplastic elastomer (TPE). Such a relatively flexible plastic may have a shore hardness of, for example, 20 Shore A to 80 Shore D.

[0112] The term "relatively rigid" should be understood to mean that the plastic from which the handle 2 is made has a greater rigidity than the plastic from which the main application member 3 and the auxiliary application member 4 are made. Similarly, the term "relatively flexible" should be understood to mean that the plastic from which the main application member 3 and the auxiliary application member 4 are made has a greater flexibility than the plastic from which the handle 2 is made.

[0113] Advantageously, the material making the handle 2 and the material making the main application member 3 and the auxiliary application member 4 have a difference in hardness of at least 10 Shore units, and even better at least 20 Shore units.

[0114] Advantageously, the main application member 3 and the auxiliary application member 4 are assembled to the handle 2 of the applicator 1 by overmolding.

[0115] To this end, the first and second ends 21, 22 of the handle 2 advantageously have protrusions defining hollow portions to facilitate attachment of the main application member 3 and the auxiliary application member 4 to the handle 2 by overmolding.

[0116] The first end 21 of the handle 2 which receives the main application member 3 therefore has an arc 210 which defines a hollow with the body of the handle 2, into which the component material of the main application member 3 penetrates during overmolding of the main application member 3 onto the handle 2.

[0117] The second end 22 of the handle 2 which receives the auxiliary application member 4 therefore has a stud 220, optionally provided with a radial groove, which makes it possible to define a relief to facilitate attachment of the auxiliary application member by overmolding onto the second end 22 of the handle 2.

[0118] As a variant, the stud is adapted to be inserted by gripping inside a complementary housing provided in the auxiliary application member 4 .

[0119] According to yet another variant, the main application member 3 and / or the auxiliary application member 4 are co-injected with the handle 2 .

[0120] The present invention also relates to an assembly, shown in FIG. 8, comprising the applicator 1 previously described, a container 5 containing a product P to be applied using the applicator, and, in the present case, an eyeliner composition to be applied to the eyelids.

[0121] A method according to the invention for stamp application of an eyeliner composition to the eyelid using the applicator previously described will now be described with reference to Figures 5 and 8-11.

[0122] In a first step of the method according to the invention, an assembly for packaging and applying a cosmetic product as previously described and seen in FIG. 8 is provided.

[0123] In a second step, at least a portion of the pre-application surface 30 is loaded with the cosmetic product P to be applied, in this case an eyeliner composition, by placing said portion of the pre-application surface 30 in contact with the cosmetic product P contained in the container 5.

[0124] According to a first gesture of use, the user loads the cosmetic product P, in this case an eyeliner composition, which is to be applied to the entire pre-application surface 30, by contacting the entire pre-application surface 30 with the cosmetic product P contained in the container 5.

[0125] According to a second gesture of use, the user can load the entire pre-application surface 30 or only a part of the pre-application surface 30, for example the central or side part of the pre-application surface, in particular the side half, with the cosmetic product P to be applied, in this case an eyeliner composition, by contacting the entire pre-application surface 30 or only a part of the pre-application surface 30 with the cosmetic product P contained in the container 5.

[0126] In a third step, as can be seen in FIG. 9 , the cosmetic product P loaded on the pre-application surface 30 is applied to the eyelid by bringing the pre-application surface 30 into contact with the eyelid in order to deposit, by stamping, a line t of the cosmetic product P, the shape and contour of which substantially corresponds to the shape and contour of the portion of the pre-application surface 30 placed in contact with the eyelid, the transverse axis Y of the application member 3 preferably extending substantially parallel to the line of eyelash implantation and the longitudinal axis X of the application member 3 preferably being arranged substantially perpendicular to the surface of the eyelid.

[0127] According to a first gesture of use, the user places substantially all of the pre-application surface 30 in contact with the skin in order to deposit, by stamping, a trace of the cosmetic product P, the shape and contour of which substantially corresponds to the shape and contour of the pre-application surface 30, on the skin.

[0128] Thus, according to this first gesture of use, application of an eyeliner trace t, the shape and contour of which substantially corresponds to that of the front application surface 30, to the eyelid is achieved by placing the product-loaded front application surface 30 in contact with the eyelid at the root of the eyelashes, with the transverse axis Y of the applicator member 3 extending substantially parallel to the line of implantation of the eyelashes and the longitudinal axis X of the applicator member 3 preferably extending substantially perpendicular to the eyelid, and by rolling the front application surface 30 over the eyelid by rotation of the applicator member 3 about the front-to-back axis Z, alternating in first and second rotational directions, as shown in FIG. 12 .

[0129] In this FIG. 12, the applicator 1 is shown in three successive positions of stamp application making it possible to create a complete line of eyeliner on the eyelid with a first gesture of use, the longitudinal axes X1, X2, X3 occupying three successive positions on the eyelid along the eyelash implantation line and extending in each case substantially perpendicular to the eyelid, the front application surface 30 then being adapted to roll over the eyelid by rotation of the applicator member 3 about the front-to-rear axis Z, alternating in a first and a second rotational direction, as indicated by the double arrow in FIG. 12.

[0130] The outwardly convex shape of the pre-application surface 30 when viewing the applicator member 3 in the plane defined by the longitudinal axis X and the transverse axis Y advantageously facilitates this rolling movement of the pre-application surface 30 on the eyelid upon rotation of the applicator member 3 about the anterior-posterior axis Z.

[0131] According to a second gesture of use, the user loads all or part of the pre-application surface 30 with cosmetic product and places only a portion of the product-loaded surface 30, for example a central or side portion of the pre-application surface 30, in contact with the skin, in order to deposit, by stamping, a trace of the cosmetic product, the shape and contour of which substantially corresponds to the shape and contour of the portion of the pre-application surface 30 placed in contact with the skin.

[0132] Thus, according to this second gesture of use, the application of an eyeliner trace onto the eyelid, the shape and contour of which substantially corresponds to that of the portion of the front application surface 30 placed in contact with the eyelid, is performed by placing a portion of the front application surface 30 loaded with product in contact with the eyelid at the root of the eyelashes, as shown in FIG. 13, with the transverse axis Y of the applicator member 3 extending substantially parallel to the eyelash implantation line and in particular with the longitudinal axis X of the applicator member 3 extending substantially perpendicular to the eyelid, preferably without the front application surface 30 rolling on the eyelid.

[0133] In this figure 13, the applicator 1 is shown in five successive positions of stamp application that allow a second gesture of use to create a complete line of eyeliner on the eyelid, with the longitudinal axes X1, X2, X3, X4, X5 occupying five successive positions on the eyelid along the line of implantation of the eyelashes and each time extending substantially perpendicular to the eyelid. Unlike the first gesture of use, in the second gesture of use the applicator does not tingled around the anterior-posterior axis and the user applies the product to the eyelid by light contact and moves the applicator perpendicular to the eyelid.

[0134] According to advantageous conditions of the method according to the invention, several successive steps of application to the eyelid of the eyeliner composition P loaded on the front application surface 30 are carried out in order to form a line of eyeliner on the eyelid between the edges of the eyelid located in the region of the inner corner C1 and the outer corner C2 of the eye, at the base of the eyelashes and along the entire length of the eyelid, as can be seen in FIG. 11 .

[0135] As can be seen in this FIG. 11, the lines of eyeliner composition P successively deposited on the skin are adjacent to one another and partially overlap to form together on the skin a continuous curved line T that follows the topology of the eyelid, at the base of the eyelashes, between the edges of the eyelid located in the areas of the inner corner C1 and outer corner C2 of the eye.

[0136] FIG. 5 shows the successive application by stamping three traces t1, t2, t3 of eyeliner by the applicator of FIGS. 1 to 4 according to a first gesture of use, in which the user loads the entire front application surface with product P and applies the loaded product to the eyelid by rolling the front application surface 30 over the eyelid and bringing the entire front application surface 30 into contact with the eyelid at the root of the eyelashes by rotation of the applicator member 3 about its anterior-posterior axis alternately in a first and a second rotational direction as shown in FIG. 12, with the transverse axes Y1, Y2, Y3 of the applicator member 3 extending substantially parallel to the line of implantation of the eyelashes and preferably with the longitudinal axes X1, X2, X3 of the applicator member 3 extending substantially perpendicular to the eyelid.

[0137] According to advantageous conditions of the method according to the invention by the first or second gesture of use and as represented in FIG. 5, two adjacent lines t1, t2, t3 of eyeliner composition P successively deposited on the skin overlap over a length Lsp1, Lsp2 of 0.5 mm to 5 mm, preferably 1 to 3 mm, in particular about 2 mm.

[0138] This overlap length Lsp1, Lsp2 of the first and second adjacent lines t1, t2 and t2, t3 is measured along the transverse axis Y2, Y3 of the applied second line t2, t3.

[0139] Thus, in the embodiment shown in FIG. 5, the overlap length Lsp1 between the first line t1 and the second line t2 is measured along the transverse axis Y2 of the second line t2, and the overlap length Lsp2 between the second line t2 and the third line t3 is measured along the transverse axis Y3 of the third line t3.

[0140] Furthermore, and according to another advantageous condition of the method according to the invention, the successive steps of applying the eyeliner composition P using the pre-application surface 30 are carried out by imparting an angular shift α1, α2 about the longitudinal axis X between a first line tn and an adjacent line tn+1 of the eyeliner composition.

[0141] Thus, and as can be seen in FIG. 5 , the first line t1 of eyeliner composition P is layered on the eyelid by placing the transverse axis Y1 at a first angular orientation about the longitudinal axis X that is intended to be adapted to the location on the eyelid where it is desired to apply the first line t1 of eyeliner composition P.

[0142] A second line t2 is then applied by angularly shifting the applicator member about its longitudinal axis X by an angle α1 and by partially overlapping the second line t2 with the first line t1 over an overlap length Lsp1.

[0143] A third line t3 is then applied by angularly shifting the applicator member about its longitudinal axis X by an angle α2 and by partially overlapping the third line t3 with the second line t2 over an overlap length Lsp2.

[0144] In the illustrated embodiment, the overlap lengths Lsp1, Lsp2 between the first and second lines t1, t2 on the one hand and the second and third lines t2, t3 on the other hand are equal.

[0145] However, these overlap lengths Lsp1, Lsp2 may be different without departing from the spirit of the invention, the essential feature being that all of the lines form a continuous curved line T that follows the topology of the eyelid at the base of the eyelashes between the edges of the eyelid located in the area of ​​the inner corner C1 and the outer corner C2 of the eye.

[0146] Similarly, in the illustrated embodiment, the shift angles α1, α2 about the longitudinal axis X between the transverse axes of the first and second lines t1, t2 on the one hand and the transverse axes of the second and third lines t2, t3 on the other hand are identical.

[0147] However, the shift angles α1, α2 may be different without departing from the spirit of the invention, the essential feature being that all of the lines form a continuous curved line T that follows the topology of the eyelid at the base of the eyelashes between the edges of the eyelid located in the area of ​​the inner corner C1 and the outer corner C2 of the eye.

[0148] Furthermore, in the illustrated embodiment, the three lines t1, t2, t3 are applied together to form a continuous curved line T that follows the topology of the eyelid at the base of the eyelashes between the edges of the eyelid located in the area of ​​the inner corner C1 and the outer corner C2 of the eye, although this line T can be made of more or less than three lines.

[0149] In particular, and as can be seen in FIG. 13, the second gesture of use of the applicator member according to the present invention imposes a greater number of successive applications to form a complete line of eyeliner at the base of the eyelashes as the first gesture of use.

[0150] In the illustrated exemplary embodiment, a complete line of eyeliner at the base of the eyelashes from the inner corner C1 of the eye to the outer corner C2 of the eye is created in three successive applications if the user employs the first gesture of use seen in FIG. 12, and in five successive applications if the user employs the second gesture of use shown in FIG. 13.

[0151] As can be seen in FIG. 5, the elliptical shape of the pre-applied surface projecting in planes Y, Z combined with the partial overlap of two adjacent lines t1, t2, t3 makes it possible to create a resulting line T whose contour is both curved and continuous, i.e., essentially without a recess / distinct angle, in particular at the junction between two adjacent lines.

[0152] Advantageously, and as shown in FIG. 11, the method according to the invention comprises the additional step of: - loading the application sides 35, 36 with the eyeliner composition P to be applied by placing said application sides 35, 36 in contact with the eyeliner composition P contained in the container 5; - applying the eyeliner composition P loaded on the application side 35, 36 to the skin, in particular at the inner corner C1 of the eyelid, by placing it in contact with the skin, in order to deposit on the skin a line of eyeliner composition P, the shape and contour of which substantially corresponds to the shape and contour of the application sides 35, 36, the longitudinal axis X of the application member 3 being preferably arranged substantially parallel to the surface of the skin, said line deposited by the application sides 35, 36 being adjacent to and partially overlapping the line t of eyeliner composition P deposited by the previous application side 30; The method may include the additional step of:

[0153] Finally, the method according to the invention may advantageously comprise a step of completing the application of the eyeliner composition to the eyelid by forming an upturned V at the outer corner C2 of the eye as shown in Figures 10 and 11.

[0154] The method according to the invention therefore advantageously comprises the additional step - loading the eyeliner composition P to be applied onto the auxiliary application surface 40 of the auxiliary application member 4 by placing said auxiliary application surface 40 in contact with the eyeliner composition P contained in a container 5; - applying the eyeliner composition P loaded on the auxiliary application surface 40 to the skin, in particular at the outer corner C2 of the eyelid, by placing it in contact with the skin in order to deposit on the skin by stamping a line ts of the eyeliner composition P, the shape and contour of which substantially corresponds to the shape and contour of the auxiliary application surface 40, said line tss deposited by the auxiliary application surface 40 being adjacent to the line t of the eyeliner composition P deposited by the front application surface 30; The method includes the additional step of:

[0155] Thus, the application member 3, applicator 1 and method according to the invention make it possible to apply by stamping to the eyelid a line T which follows the topology of the eyelid at the base of the eyelashes, between the edges of the eyelid located in the region of the inner corner C1 and the outer corner C2 of the eye, the contour of the line T being both curved and continuous, i.e. having substantially no recess / distinct angle at the junction between two consecutively superimposed adjacent lines.

[0156] By the method according to the invention, the eyes can be easily, ergonomically, accurately and completely made up with an eyeliner composition, by successive stamping operations, comprising a line T extending across the eyelid at the base of the eyelashes between the inner corner C1 and the outer corner C2 of the eye, and also a flick V located at the outer corner of the eye.

[0157] 14 to 21 show an applicator 1' for stamp application of a cosmetic product P to the skin, in particular for application of an eyeliner to the eyelids, in a second embodiment.

[0158] In these figures, elements that are identical or similar to those in the first embodiment of the applicator are designated by the same reference numerals with the addition of the punctuation mark '.

[0159] Those elements common between the first and second embodiments of the applicator according to the present invention will not be described in detail again, and only the elements that distinguish the second embodiment from the first embodiment will be the subject of the detailed description below.

[0160] As can be seen particularly in Figures 14, 15, 19 and 20, the applicator 1' includes a handle 2' that extends along a longitudinal axis X' between a first end 21' and an opposing second end 22'.

[0161] A first end 21' of the handle 2' carries an application member 3' or main application member and a second end 22' of the handle 2' carries an auxiliary application member 4'.

[0162] In these implementations shown in Figures 14, 15, 19 and 20, this auxiliary application member 4' is identical to the one described in connection with the first embodiment of the applicator according to the invention.

[0163] As a variant, the second end 22' of the handle 2' may be provided with an eyeliner application nib, for example a nib made of a fibrous material, for example felt, or a nib made of an elastomer. Such an eyeliner application nib is advantageously fluidly connected to an eyeliner reservoir integrated in the handle 2', in particular so that the eyeliner is supplied by capillary action or flow.

[0164] The main application member 3' is in the form of a tip connected to a first end 21' of the handle 2' that can be handled by a user.

[0165] The main application member 3', provided for stamp application of a cosmetic product P to the skin, in particular for application of eyeliner to the eyelids, defines a longitudinal axis X, a transverse axis Y perpendicular to the longitudinal axis X, and a front-to-back axis Z perpendicular to the longitudinal axis X and to the transverse axis Y.

[0166] As can be seen in Figures 14, 15, 19 and 20, when the applicator member 3' is attached to the first end 21' of the handle 2', the longitudinal axis X of the main applicator member 3' coincides with the longitudinal axis X' of the handle 2'.

[0167] As can be seen in these figures, the main application member 3' has a pre-application surface 30' suitable for being placed in contact with the skin, in this case the eyelid, in particular at the base of the eyelashes, for loading the cosmetic product P to be applied, in this case an eyeliner composition, by placing at least a part of the pre-application surface 30' in contact with the cosmetic product P, and for depositing on the skin by stamping a line of product P, the shape and contour of which substantially corresponds to the shape and contour of the part of the pre-application surface 30' placed in contact with the skin.

[0168] The main application member 3' has, along a longitudinal axis X, a first end 37' constituting an end for attachment to the handle 2' and an opposite second end 38' carrying the front application surface 30'.

[0169] As described in connection with the first embodiment of the applicator 1 according to the present invention, the front application surface 30' has an elongated shape along the transverse axis Y that is outwardly convex when the application member 3' is viewed in the plane defined by the longitudinal axis X and the transverse axis Y.

[0170] Similarly, pre-application surface 30' further has a width l' measured along transverse axis Y between first lateral end 31' and opposite second lateral end 32'.

[0171] The width l' of the pre-application surface 30' is advantageously between 10 and 20, in particular about 15 mm.

[0172] Furthermore, as can also be seen in Figure 16, the front application surface 30' of the application member 3' belonging to the applicator 1' according to the second embodiment of the present invention has a curved contour defining a concave surface C when the application member 3' is viewed in a plane defined by the transverse axis Y and the longitudinal axis Z.

[0173] The curved profile of pre-application surface 30' in the plane defined by transverse axis Y and longitudinal axis Z extends along curved axis Ac.

[0174] This curved axis Ac advantageously forms a circular arc with a radius of curvature R less than or equal to 60 mm, in particular between 30 mm and 200 mm.

[0175] In the implementation shown in FIGS. 14-21, as can be seen particularly in FIG. 17, the radius of curvature R of the curved axis Ac is about 50 mm.

[0176] The concave surface C defined by the curved contour of the pre-applied surface 30' in the planes Y, Z advantageously has a depth p along the Z axis of between 0.2 mm and 1.5 mm. In particular, in the implementation shown in FIG. 17, this depth p is about 0.7 mm.

[0177] According to these conditions, the curvature of the front application surface 30' in the plane defined by the transverse axis Y and the anterior-posterior axis Z is particularly well suited to enhance the ease, ergonomics and precision of stamping a line of eyeliner at the root of the eyelashes, the concave surface C defined by this curved contour being adapted to the curvature of the lash line so that the applied line of eyeliner follows this lash line as closely as possible.

[0178] Advantageously, in the implementations shown in Figures 14-21, the cross-section of the handle 2' in the plane defined by the transverse axis Y and the longitudinal axis Z also has a curved profile defining a concave surface C' having the same orientation as the concave surface C defined by the curved profile of the front application surface 30' in this same plane defined by the transverse axis and the longitudinal axis.

[0179] The curved contour of the front application surface 30' belonging to the application member 3' in the plane defined by the transverse axis Y and the longitudinal axis Z, as well as the curved contour of the cross section of the handle 2' in this same plane, are symmetrical with respect to the plane defined by the longitudinal axis X and the longitudinal axis Y. In other words, the curved contour of the front application surface 30' belonging to the application member 3' in the plane defined by the transverse axis Y and the longitudinal axis Z, as well as the curved contour of the cross section of the handle 2' in this same plane, are centred relative to one another on the axes Y, Z. Preferably, these two curved contours are also centred relative to one another on the longitudinal axis X.

[0180] According to these conditions, the handle 2' and the application member 3' of the applicator 1' both have a concave shape with the same orientation along the longitudinal axis X in the plane defined by the transverse axis Y and the longitudinal axis Z, so that the user intuitively and ergonomically decides how to hold the applicator 1' in order to orient the concave surface C of the front application surface 30' of the application member 3' appropriately relative to her eyelid, i.e. in the direction of the eye that is to be made up.

[0181] The curved profile of the cross section of the handle 2' in the plane defined by the transverse axis Y and the longitudinal axis Z advantageously extends along a curved axis Ac'.

[0182] This curved axis Ac' advantageously forms a circular arc having a radius of curvature R' preferably between 10 mm and 35 mm.

[0183] In the implementation shown in FIGS. 14-21, as can be seen particularly in FIG. 18, the radius of curvature R' of the curved axis Ac' is about 15 mm.

[0184] The concave surface C' defined by the curved contour of the cross section of the handle 2' in the plane Y, Z advantageously has a depth p' along the Z axis of between 0.4 mm and 3 mm. In particular, in the implementation shown in Figure 17, this depth p' is about 0.9 mm.

[0185] The curvature of the handle 2' in the plane defined by the transverse axis Y and the longitudinal axis Z is therefore more pronounced than the curvature of the front application surface 30' in this same plane.

[0186] In other words, the radius of curvature R' of the handle 2' in the plane defined by the transverse axis Y and the longitudinal axis Z is less than the radius of curvature R of the front application surface 30' in this same plane.

[0187] The more pronounced curvature of the handle 2' in the plane defined by the transverse axis Y and the longitudinal axis Z clearly indicates to the user the proper orientation for handling and manipulating the applicator 1'.

[0188] As can be seen particularly in FIG. 16, the thickness e of pre-coat surface 30' is substantially constant as it moves along transverse axis Y following curved axis Ac.

[0189] First and second edges 33', 34' of front application surface 30' meet at first lateral end 31' and second lateral end 32' to form a rounded shape.

[0190] The front application surface 30' projects above a plane defined by the transverse axis Y and the longitudinal axis Z and has a curved, substantially oblong shape.

[0191] According to advantageous conditions, the first edge 33' and the second edge 34' of the pre-application surface 30' have rims, in particular at the first lateral end 31' and the second lateral end 32', which protrude from the pre-application surface 30' along the longitudinal axis.

[0192] Such a rim, the protruding distance of which along the longitudinal axis X relative to the pre-application surface 30' may be, for example, between 0.05 mm and 1 mm, or even 1.5 mm, advantageously makes it possible to create a reserve of cosmetic product between the pre-application surface 30' and this protruding rim, thus increasing the amount of cosmetic product that can be carried on the application member 3' and enhancing its autonomy and reducing the frequency with which the user has to load it with product.

[0193] Advantageously, the application sides 35', 36' each have indentations 350', 360' in the plane defined by the longitudinal axis X and the transverse axis Y, as can be seen in FIGS.

[0194] The height hf of the applicator member 3' along the longitudinal axis X is therefore reduced at its sides compared to the height h of its central part. Those sides of the applicator member 3' which have the indentations 350', 360' perpendicular thereto are therefore more flexible than the central part of the applicator member 3', in particular in the direction of the longitudinal axis X and the longitudinal axis Z.

[0195] As can be clearly seen in FIG. 21 which shows an eyeliner line T' obtained after successive application of three lines of eyeliner t1', t2', t3' by use, in a first gesture of use, of an application member 3', similar to FIG. 5, whose front application surface 30' is outwardly convex when viewed in the plane X, Y and has a curved contour defining a concave surface C when viewed in the plane Y, Z, a continuous, sharp and non-concave line T' can be created, with a relatively pronounced curvature, following the topology of the eyelid, where the eyeliner is applied to the root of the eyelashes.

[0196] In one implementation of the invention, the application member 3, 3' or at least the front application surface 30, 30' of the application member 3, 3' and / or the auxiliary application member 4, 4' or at least the auxiliary application surface 40, 40' is / are adapted to have a flocking.

[0197] The application members 3, 3' according to the first and second embodiments can be used with a first or a second gesture of use. [Explanation of symbols]
