Description

DESCRIPTION

Application member for applying cosmetic product by stamping on the skin

The present invention relates to the field of applicators for applying a cosmetic product to the skin, especially applicators for applying a make-up product to the eyes and in particular applicators for applying an eyeliner to the eyelids.

In this field, it is known to manufacture the applicator in the form of a pencil whose lead forms an application member that allows one to draw a line of eyeliner on the eyelids, at the base of the eyelashes and/or that allows one to draw a tail at the outer corner of the eye.

In this field, applicators are also known in the form of a pen with a hollow body that forms a product container that communicates with an application member that has the shape of a tip made of a porous material, generally a felt, fed with product by capillary action and that allows a line of eyeliner to be drawn on the eyelids, at the base of the eyelashes, and/or that allows a tail to be drawn at the outer corner of the eye.

Furthermore, in this field there are applicators in the form of dip applicators, which comprise a handling element, a stem and an application member supported at the end of the stem and intended to be dipped into a container containing the product to be applied in order to be loaded with the product and to allow a line of eyeliner to be drawn on the eyelids, at the base of the eyelashes, and/or to allow a tail to be drawn at the outer corner of the eye.

However, the use of such eyeliner drawing applicators, whereby the applicator member is placed in contact with the eyelid and moved parallel to the lash line to draw a line of eyeliner, requires a certain amount of practice and a certain dexterity to draw a defined, continuous and precise line of eyeliner on the eyelids.

Furthermore, particularly in the case of older users, the drawing action associated with the eyeliner applicator may cause a certain amount of deformation of the eyelid as the applicator member is passed over the eyelid, which tends to create an uneven line and intensify the fine lines of the eyelid.

Thus, in order to overcome these drawbacks, applicators have been developed which are equipped with members for applying a cosmetic product by stamping onto the skin. In such applicators, the application member has an application surface suitable for being loaded with cosmetic product by placing the application surface in contact with the cosmetic product and for being placed at least partially in contact with the skin to deposit by stamping thereon a line or a stroke of cosmetic product whose shape and contour substantially correspond to the shape and contour of the part of the application surface placed in contact with the skin.

By means of such applicators, the action of applying a cosmetic product, and in particular eyeliner, to the eyelids is facilitated, since the stamping action is easier to control for inexperienced users than that in which a line of eyeliner is drawn using an application member that slides along the eyelid.

Furthermore, with such stamping applicators, the eyelid is not deformed during the application of the eyeliner and thus the eyeliner line formed in this way is sharper and more precise, particularly in the case of older users, whose eyelids tend to deform or fold easily when an application member is slid over them.

Document FR3026620 in the name of the present applicant describes such a stamping applicator, wherein the application member is provided at the end of a handle and is in the form of a spatula, one of whose drop-shaped faces is provided to allow the application by stamping of a line of eyeliner forming a corner of the eye.

However, with such an applicator, only the corner of the eye can be formed on a user's eyelids and the applicator member is not suitable for forming an eyeliner line on the eyelids at the base of the eyelashes.

US9635924 also describes a stamping applicator in which the applicator member received at the end of a handle has an overall triangular shape and is intended only for stamping application from the corner of the eye to the outer corner of the eyes and is not suitable for forming a line of eyeliner on the eyelids at the base of the eyelashes. FR3031282 describes an applicator for stamping a cosmetic product onto the skin.

The present invention is intended to overcome these drawbacks and, to this end, proposes an application member for applying a cosmetic product by stamping on the skin, in particular for applying eyeliner to the eyelids, defining a longitudinal axis, a transverse axis perpendicular to the longitudinal axis and an antero-posterior axis perpendicular to the longitudinal axis and the transverse axis, and having a front application surface suitable to be loaded with cosmetic product by placing the front application surface in contact with the cosmetic product and to be placed at least partially in contact with the skin to deposit by stamping thereon a line or a stroke of cosmetic product whose shape and contour substantially correspond to the shape and contour of the part of the front application surface placed in contact with the skin, wherein the front application surface has an elongated shape along the transverse axis and is convex outwards when the application member is viewed in the plane defined by the longitudinal axis and the transverse axis and wherein the front application surface has a curved contour defining a concavity when the application member is viewed in the plane defined by the transverse axis and the anteroposterior axis.

By these arrangements, the application of an eyeliner line on the eyelid, the shape and contour of which correspond to those of the part of the front application surface placed in contact with the skin, is carried out in an easy and ergonomic manner for an inexperienced user, and in a precise manner for an older user, by placing at least a part of the front application surface in contact with the eyelid, at the base of the eyelashes, with the transverse axis of the application member extending substantially parallel to the lash line and in particular with the longitudinal axis of the application member extending substantially perpendicular to the eyelid.

A user can adopt different gestures to apply the cosmetic product by stamping using the application member according to the invention.

In a first gesture of use, the user loads the entire front application surface with the cosmetic product and places substantially the entire front application surface in contact with the skin to deposit on it by stamping a line of a cosmetic product whose shape and contour substantially correspond to the shape and contour of the front application surface.

In this manner, the application of an eyeliner line to the eyelid whose shape and contour substantially correspond to that of the front application surface is achieved by placing the product-loaded front 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 eyelash implantation line and preferably with the longitudinal axis of the applicator member extending substantially perpendicular to the eyelid, and rolling the front application surface over the eyelid by rotating the applicator member about the anteroposterior axis alternately in a first and a second direction of rotation.

The outwardly convex shape of the frontal application surface, when the applicator member is viewed in the plane defined by the longitudinal axis and the transverse axis, advantageously facilitates this rolling movement of the frontal application surface on the eyelid, by rotating the applicator member around the anteroposterior axis.

In a second gesture of use, the user loads all or part of the front application surface with the cosmetic product and places only a part of the front application surface loaded with the product, for example a central part or a lateral part, in particular a lateral half, of the front application surface, in contact with the skin to deposit on it by stamping a line of cosmetic product whose shape and contour substantially correspond to the shape and contour of the part of the front application surface placed in contact with the skin.

In this way, the application of an eyeliner line on the eyelid whose shape and contour substantially correspond to those of the part of the front application surface placed in contact with the skin is achieved by placing a part of the front application surface loaded with the product in contact with the eyelid, at the base of the eyelashes, with the transverse axis of the applicator member extending substantially parallel to the eyelash implantation line, in particular with the longitudinal axis of the applicator member extending substantially perpendicular to the eyelid and preferably without rolling the front application surface over the eyelid.

If the dimensions of the applicator member are such that several successive adjacent applications are needed to achieve the application of a complete line of eyeliner on an eyelid at the base of an eyelash, this line extending from the outer corner of an eye to the inner corner of an eye, then, with the first gesture, the user can advantageously achieve the application of a complete line of eyeliner in a smaller number of successive applications compared to the second gesture. However, this first gesture requires rolling the front application surface on the eyelid, by rotating the applicator member about the anterior-posterior axis, which may be complicated for some users who prefer to adopt the second gesture, even if it requires a greater number of successive applications to form a complete line of eyeliner at the base of the lashes.

An application member according to the invention may be in the form of a tip which may be connected to a handle and, in particular, to an end of a handle which may be manipulated by a user.

The application element according to the invention is advantageously used at the end of a handle that can be manipulated by the user. Thus, the application member has, along the longitudinal axis, an end for fixing to a handle and an opposite application end supporting the front application surface.

The expression "elongated shape along the transverse axis" for the front application surface should be understood to mean that the front application surface has a larger dimension along the transverse axis than along the antero-posterior axis or along the longitudinal axis.

This elongated shape of the front application surface makes it possible, by stamping on the skin, to form a line whose shape and contour correspond to the shape and contour of the part of the front application surface placed in contact with the skin and, in this way, elongated, on the eyelid, at the base of the eyelashes.

Furthermore, the expression "front application surface which is convex towards the outside when the application member is viewed in the plane defined by the longitudinal axis and the transverse axis" should be understood to mean that the intersection between the front application surface and any plane parallel thereto defined by the longitudinal axis and the transverse axis is a curved segment, in particular a circular segment, which is convex towards the outside of the application member.

The outwardly convex profile of the front application surface in the plane defined by the longitudinal axis and the transverse axis makes it possible to easily and precisely apply, by stamping, a line of eyeliner at the base of the eyelashes, both on the domed part of the eyelid and also on the hollow parts of the eyelid located in the region of the inner and outer corners of an eye.

Furthermore, this outwardly convex profile of the front application surface promotes the rolling movement of the front application surface on the eyelid, by rotating the applicator member around the antero-posterior axis, within the framework of the first gesture of use described above.

The expression "front application surface having a curved contour defining a concavity when the application member is viewed in the plane defined by the transverse axis and the antero-posterior axis" should be understood to mean that the intersection between the front application surface and any plane parallel thereto defined by the transverse axis and the antero-posterior axis, or the cross-section of the front application surface in the plane parallel thereto defined by the transverse axis and the antero-posterior axis, has a closed curved contour, in particular bean-shaped extending along a curved extension axis, especially an arc of a circle.

The curved contour of the front application surface in the plane defined by the transverse axis and the antero-posterior axis makes it possible to further improve the ease, ergonomics and precision of application by stamping a line of eyeliner at the base of the eyelashes, whereby the concavity defined by this curved contour adapts to the curvature of the lash line, so that the applied line of eyeliner follows this lash line as precisely as possible.

According to other advantageous aspects, the applicator according to the invention as defined in claim 1 incorporates one or more of the following features:

- the front application surface has a circular profile when the application member is viewed in the plane defined by the longitudinal axis and the transverse axis, said circular profile preferably having a radius of curvature less than or equal to 60 mm, in particular between 30 mm and 50 mm, in particular approximately 40 mm. By these arrangements, the curvature of the front application surface in the plane defined by the longitudinal axis and the transverse axis is particularly suitable for a defined and precise application of the eyeliner both on the domed part of the eyelid and also on the hollow parts of the eyelid located in the region of the inner and outer corners of an eye. Furthermore, said curvature of the front application surface in the plane defined by the longitudinal axis and the transverse axis facilitates the rolling movement of the front application surface on the eyelid, by rotating the application member around the antero-posterior axis within the framework of the first gesture of use set out above.

- the curved contour of the front application surface in the plane defined by the transverse axis and the antero-posterior axis extends along a curved axis, said curved axis advantageously forming an arc of a circle preferably having a radius of curvature comprised between 30 mm and 200 mm, and in particular of approximately 50 mm. By these arrangements, the curvature of the front application surface in the plane defined by the transverse axis and the antero-posterior axis is particularly suitable for further improving the ease, ergonomics and precision of the application by stamping of a line of eyeliner at the base of the eyelashes, wherein the concavity defined by this curved contour adapts to the curvature of the eyelash line, so that the applied line of eyeliner follows this eyelash line as precisely as possible.

- the front application surface is substantially flat when the application member is viewed in the plane defined by the longitudinal axis and the antero-posterior axis. In other words, the intersection between the front application surface and any plane parallel thereto defined by the longitudinal axis and the antero-posterior axis is a substantially rectilinear segment. Thanks to these provisions, an applicator member is provided which ensures a certain comfort of application, in which the application surface does not have in the plane defined by the longitudinal axis and the antero-posterior axis any annoying, even potentially harmful, edge when placed in contact with the skin, while ensuring a controlled, constant and relatively thin width of the line of cosmetic product on the skin, and in particular of the line of eyeliner applied to the eyelids.

- 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 extremity and an opposite second lateral extremity and a thickness measured along the antero-posterior axis between a first edge and a second opposite edge, and the thickness of the front application surface varies when moving along the transverse axis, and is minimum at the first lateral extremity and/or at the second lateral extremity. By these arrangements, a stamping application member is obtained, the front application surface of which is tapered in the direction of one or both of its lateral extremities, making it possible to apply to the eyelid, and in particular to the ends of the eyelid located in the region of the inner and outer corners of the eye, a line of eyeliner at the tapered end, which contributes to the aesthetic appeal of the resulting make-up. Furthermore, by the shape of the front application surface of the application member which is thinned at the lateral extremities, it is possible to apply a curved eyeliner line, which follows the curvature of the eyelid at the base of the eyelashes, formed from multiple adjacent lines deposited by stamping using the application member, with an angular displacement around the longitudinal axis between the adjacent lines, so as to form a substantially continuous contour, i.e. a contour which has substantially no sharp recesses/angles, in particular at the junction between two adjacent lines. As a variant, the thickness of the front application surface is substantially constant when moving along the transverse axis. In particular, when the front application surface has a curved contour in the plane defined by the transverse axis and the antero-posterior axis, said contour extending along a curved axis forming an arc of a circle, the thickness of the front application surface is substantially constant when moving along this curved axis. By these arrangements, a line of cosmetic product applied to the skin by the front application surface will correspondingly have a substantially constant thickness throughout its length. This constant thickness of the front application surface when viewed in the plane defined by the transverse axis and the antero-posterior axis, combined with the curved contour of the front application surface in this same plane, also advantageously allows to apply a curved line of eyeliner, following the curvature of the eyelid at the base of the eyelashes, formed from multiple adjacent lines deposited by stamping using the application member, with an angular displacement around the longitudinal axis between the adjacent lines, to form a substantially continuous contour, i.e. a contour having substantially no sharp recesses/angles, in particular at the junction between two adjacent lines.

- the thickness of the front application surface is minimal, and in particular zero, at the first lateral end and/or at the second lateral end, the first and second edges of the front application surface meeting at the first lateral end and/or at the second lateral end. Thanks to these arrangements, an applicator member is provided for drawing a line of eyeliner on the eyelid whose ends located at the inner and outer corners of the eye are thin and aesthetic.

- the thickness of the front application surface varies continuously as it moves along the transverse axis, said front application surface having, in projection on a plane perpendicular to the longitudinal axis, a substantially oval shape, in particular an ellipsoidal shape. As a variant, the first and second edges of the front application surface meet at the first lateral end and/or at the second lateral end forming a rounded shape, said front application surface having, in projection on the plane defined by the transverse axis and the antero-posterior axis, a substantially oblong curved shape. Such shapes are particularly suitable for allowing adjacent lines of eyeliner to be formed on the eyelid, successively deposited by partially overlapping at their ends, so as to jointly form on the eyelid a continuous line, in particular a curved line, of eyeliner over the entire length of the eyelid, adapting to the topology thereof. Such a particular shape makes it possible to apply a curved line of eyeliner, following the curvature of the eyelid at the base of the eyelashes, formed from multiple adjacent lines deposited by stamping using the application member, with an angular displacement around the longitudinal axis between the adjacent lines, so as to form a contour of substantially continuous curvature, i.e. a contour having substantially no sharp recesses/angles, in particular at the junction between two adjacent lines.

- the maximum thickness of the front application surface, which is preferably midway between the first and second lateral ends of the front application surface, is between 0.5 mm and 2.5 mm, and is preferably approximately 1.3 mm.

- the width of the front application surface is advantageously between 10 and 20 and in particular is approximately 15 mm.

- the first edge and/or the second edge of the front application surface has, in particular at the first and/or second lateral end, an edge protruding from the front application face along the longitudinal axis. Said protruding edge advantageously makes it possible to create a cosmetic product container between the front application surface and this protruding edge, thereby increasing the amount of cosmetic product that can be carried in the application member and improving the autonomy thereof, requiring the user to refill it with product less frequently.

In an advantageous arrangement, the application member also has a lateral application surface adjacent to the front application surface and extending substantially perpendicular thereto, said lateral application surface preferably being concave outwards when the application member is viewed in the plane defined by the longitudinal axis and the transverse axis.

The implementation of said lateral application surface forming an acute angle with the front application surface is particularly advantageous to limit the risk of smearing between a stroke of product deposited by the front application surface and a stroke of product deposited by the lateral application surface.

Furthermore, when the applicator member according to the invention is fixed to a handle, in particular with the longitudinal axis of the handle coinciding with the longitudinal axis of the applicator member, the implementation of said lateral application surface is particularly convenient in terms of ergonomics of use, in particular for depositing a stroke of product, especially eyeliner, on the inner corner of an eye while preventing the handle from hitting against the bridge of the nose, as would be the case if the application of the product on the inner corner of the eye were achieved by means of the front application surface. Indeed, in such a case, when a stroke of eyeliner is applied on the inner corner of an eye by means of the lateral application surface, the handle is positioned with its longitudinal axis extending substantially parallel to the eyelid and, in this way, the risk of hitting the bridge of the nose during this application is limited.

The expression "lateral application surface which is concave towards the outside when the application member is viewed in the plane defined by the longitudinal axis and the transverse axis" should be understood to mean that the intersection between the lateral application surface and any plane parallel thereto defined by the longitudinal axis and the transverse axis is a curved segment, in particular a circular segment, which is concave towards the outside of the application member.

The outwardly concave profile of the lateral application surface in the plane defined by the longitudinal axis and the transverse axis makes it possible to easily and precisely apply by stamping a line of eyeliner at the base of the eyelashes, in particular in the hollow parts of the eyelid located in the region of the inner and outer corners of an eye.

Preferably, the lateral application surface has a circular profile when the application element is viewed in the plane defined by the longitudinal axis and the transverse axis, said circular profile preferably having a radius of curvature comprised between 140 mm and 170 mm, in particular approximately 155 mm. By these arrangements, the curvature of the lateral application surface in the plane defined by the longitudinal axis and the transverse axis is particularly suitable for the defined and precise application of an eyeliner line, in particular in the hollow parts of the eyelid situated in the region of the inner and outer corners of the eye.

Alternatively, the lateral application surface is flat or convex outwardly when the applicator member is viewed in the plane defined by the longitudinal axis and the transverse axis.

According to an advantageous arrangement of the invention, the lateral application surface has a slit in the plane defined by the longitudinal axis and the transverse axis. With the implementation of this slit, and preferably of a slit on each lateral application surface, the height of the application member along the longitudinal axis is reduced in its lateral parts relative to the height of its central part. These lateral parts of the application member, which have slits perpendicular thereto, thus have greater flexibility, especially in the directions of the longitudinal axis and the anterior-posterior axis, than the central part of the application member. These arrangements are particularly advantageous for applying a curved line of eyeliner, following the curvature of the eyelid at the base of the eyelashes, formed from multiple adjacent lines deposited by stamping using the application member, wherein the flexibility of the lateral portions of the application member allows the user to modify the deformation of the application member to obtain a substantially continuous contour, i.e. a contour having substantially no sharp recesses/angles, in particular at the junction between two adjacent lines.

In one embodiment of the invention, it may be provided that at least the front application surface of the application member is flocked. Such flocking makes it possible, in particular, to increase the autonomy of the application member.

The present invention also relates to an applicator for applying a cosmetic product by stamping on the skin, in particular for applying eyeliner to the eyelids, comprising:

- a handle extending along a longitudinal axis between a first end and an opposite second end;

- an application member as defined above fixed to the first end of the handle, wherein said longitudinal axis of the handle preferably coincides with the longitudinal axis of the application member.

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

Advantageously, the cross section of the handle in the plane defined by the transverse axis and the anteroposterior axis has a curved contour defining a concavity, said concavity preferably having the same orientation as the concavity defined by the curved contour of the front engagement surface in the plane defined by the transverse axis and the anteroposterior axis.

Preferably, the curved contour of the front application surface belonging to the application member in the plane defined by the transverse axis and the antero-posterior axis and/or the curved contour of the cross section of the handle in this same plane is/are symmetrical with respect to the plane defined by the longitudinal axis and the antero-posterior axis.

By these arrangements, the handle and the application member of the applicator according to the invention both have a concave shape of the same orientation along the longitudinal axis in the plane defined by the transverse axis and the antero-posterior axis, so that the user intuitively and ergonomically determines how to hold the applicator in order to orient the concavity of the front application surface of the application member appropriately relative to his or her eyelid, i.e. in the direction of the eye to be made up.

Preferably, the curved contour of the cross section of the handle in the plane defined by the transverse axis and the antero-posterior axis extends along a curved axis, said curved axis advantageously forming an arc of a circle preferably having a radius of curvature comprised between 10 mm and 35 mm, and in particular approximately 15 mm.

In this way, the curvature of the handle in the plane defined by the transverse axis and the antero-posterior axis can be more pronounced than the curvature of the front application surface in this same plane. In other words, the radius of curvature of the handle in the plane defined by the transverse axis and the antero-posterior axis can be smaller than the radius of curvature of the front application surface in this same plane. This is particularly advantageous insofar as, the curvature of the front application surface being adapted to the curvature of the lash line, it can be relatively small (relatively large radius of curvature) and difficult for the user to detect in order to hold and manipulate the applicator in the appropriate orientation. The more pronounced curvature of the handle in the plane defined by the transverse axis and the antero-posterior axis more clearly indicates to the user the appropriate orientation for maneuvering and manipulating the applicator.

In an advantageous arrangement, the second end of the handle is equipped with a secondary application member having a secondary application surface suitable to be loaded with cosmetic product by placing the secondary application surface in contact with the cosmetic product and to be placed in contact with the skin to deposit by stamping thereon a line of cosmetic product whose shape and contour substantially correspond to the shape and contour of the secondary application surface, wherein the secondary application surface extends in particular in a plane forming an angle with the longitudinal axis of the handle and preferably having a triangular or drop-shaped outer contour.

This creates an applicator that allows you to simultaneously apply, by stamping, a line of eyeliner along the eyelid, at the base of the eyelashes, and a tail of eyeliner, in the shape of a triangle or a drop, in the outer corner of the eye.

In one embodiment of the invention, it may be provided that at least the secondary application surface of the secondary application member is flocked. Such flocking makes it possible, in particular, to increase the autonomy of the secondary application member.

According to a preferred embodiment of the invention, the application member and/or the secondary application member is/are fixed to the first end and/or the second end of the handle by overmolding. Such an arrangement makes it possible to simplify the manufacture of the applicator and limit the costs thereof, and also to facilitate its use in the form of a single object.

To this end, the first and second ends of the handle advantageously have protuberances defining hollow portions that promote overmolding attachment of the engagement member and/or the secondary engagement member to the handle.

As a variant, the application member and/or the secondary application member are co-injected with the handle.

Preferably, the handle is made of a relatively rigid plastic, especially a thermoplastic material, such as polypropylene (PP), polyethylene (PE), polyamide (PA) or the like. Said relatively rigid plastic may have, for example, a Shore hardness greater than 80 Shore D.

Preferably, the application member and/or the secondary application member is/are made of a relatively flexible plastic, such as a silicone, a rubber or a thermoplastic elastomer (TPE). Said relatively flexible plastic may have, for example, a Shore hardness between 20 Shore A and 80 Shore D.

The term "relatively rigid" should be understood to mean that the plastic from which the handle is made has a greater rigidity than that from which the engagement member and/or the secondary engagement member are made. Similarly, the term "relatively flexible" should be understood to mean that the plastic from which the engagement member and the secondary engagement member are made has a greater flexibility than that from which the handle is made.

Advantageously, the material from which the handle is made and the material from which the application member is made have a difference in hardness of at least 10 Shore units, better still at least 20 Shore units.

The invention also relates to an assembly for packaging and applying by stamping a cosmetic product, in particular eyeliner, according to claim 14, comprising:

- a container containing the cosmetic product to be applied;

- an applicator as described above.

According to another aspect of the present invention, there is proposed a process according to claim 15 for applying a cosmetic product to the skin, in particular for applying eyeliner to the eyelids, comprising the steps consisting of:

- providing a packaging and application assembly as described in claim 14;

- loading at least a portion of the front application surface with the cosmetic product to be applied by placing said portion of the front application surface in contact with the cosmetic product contained in the container;

- applying the cosmetic product loaded on the front application surface onto the skin by placing it in contact with the skin, preferably placing the longitudinal axis of the application member substantially perpendicular to the skin surface and, where appropriate, orienting the concavity of the front application surface in the direction of the eye, to deposit by stamping on the skin a line of cosmetic product whose shape and contour substantially correspond to the shape and contour of the part of the front application surface placed in contact with the skin.

In an advantageous arrangement, the process according to the invention comprises multiple successive steps of applying the cosmetic product loaded on the front application surface onto the skin, wherein the lines of cosmetic product successively deposited on the skin are adjacent to one another and preferably partially overlap, so as to jointly form on the skin a continuous line, in particular a continuous curved line, of cosmetic product.

By the shape of the front application surface of the application member which is tapered at the lateral extremities, it is possible to apply a curved line of eyeliner, which follows the curvature of the eyelid at the base of the eyelashes, formed from multiple adjacent lines deposited by stamping using the application member, with an angular displacement around the longitudinal axis between the adjacent lines, to form a contour of substantially continuous curvature, i.e. a contour having substantially no sharp recesses/angles, in particular at the junction between two adjacent lines.

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 approximately 2 mm.

In the case of using an application member comprising a lateral application surface, as described above, the process according to the invention advantageously comprises the following additional steps:

- load the side application surface with the cosmetic product to be applied by placing the side application surface in contact with the cosmetic product contained in the container;

- applying the cosmetic product loaded on the lateral application surface onto the skin, in particular on an inner corner of the eyelid, by placing it in contact with the skin, wherein the longitudinal axis of the application member is preferably positioned substantially parallel to the skin surface, to deposit by stamping thereon a line of cosmetic product whose shape and contour substantially correspond to the shape and contour of the lateral application surface, wherein in particular said line deposited by the lateral application surface is adjacent to, and is partially overlapped with, a line of cosmetic product deposited by the front application surface.

In the case of using an applicator provided with a secondary application member, as described above, the process according to the invention advantageously comprises the following additional steps:

- loading the secondary application surface with the cosmetic product to be applied by placing the secondary application surface in contact with the cosmetic product contained in the container;

- applying the cosmetic product loaded on the secondary application surface onto the skin, in particular on an outer corner of the eyelid, by placing it in contact with the skin to deposit by stamping thereon a line of cosmetic product whose shape and contour substantially correspond to the shape and contour of the secondary application surface, wherein preferably said line deposited by the secondary application surface is connected to a line of cosmetic product deposited by the front application surface.

By means of the process according to the invention, the eyes can be completely made up in an easy, ergonomic and precise manner by means of an eyeliner composition comprising the line extending over the eyelids at the base of the eyelashes between the inner corner and the outer corner of the eye, and also the corner situated at the outer corner of the eyes, by means of successive stamping operations.

The first end 21 of the handle 2 is equipped with an engagement member 3 or primary engagement member, and the second end 22 of the handle 2 is equipped with a secondary engagement member 4, as will be seen in more detail below.

The main application member 3 is in the form of a tip connected to the first end 21 of the handle 2 which can be manipulated by a user.

The main application member 3 provided for the stamping application of the cosmetic product P onto the skin, in particular for the application of eyeliner to the eyelids, defines a longitudinal X axis, a transverse Y axis perpendicular to the longitudinal X axis and an antero-posterior Z axis perpendicular to the longitudinal X axis and the transverse Y axis.

In the embodiments illustrated in the figures, when the engagement member 3 is fixed to the first end 21 of the handle 2, the longitudinal axis X of the main engagement member 3 coincides with the longitudinal axis X' of the handle 2.

As variants not shown, the longitudinal axis X of the engagement member 3 may be parallel to, or may form an angle with, the longitudinal axis X' of the handle 2 when the engagement member 3 is fixed to the first end 21 of the handle 2, wherein a displacement or deflection arm may connect, for example, the engagement member 3 to the first end 21 of the handle 2.

As seen in Figures 1 to 4, the main application member 3 has a front application surface 30 suitable to be loaded with the cosmetic product P to be applied, in the present case an eyeliner composition, the front application surface 30 being placed in contact with the cosmetic product P and to be placed at least partially in contact with the skin, in the present case the eyelids, especially at the base of the eyelashes, so as to deposit by stamping thereon a line of product P whose shape and contour substantially correspond to the shape and contour of the part of the front application surface 30 placed in contact with the skin.

The main application member 3 has along the longitudinal axis X a first end 37 constituting an end for fixing to the handle 2 and an opposite second end 38 supporting the front application surface 30. According to the invention, and as clearly seen in particular in Figures 3 and 4, the front application surface 30 has an elongated shape along the transverse axis Y, which is convex outwards when the application member 3 is viewed in the plane defined by the longitudinal axis X and the transverse axis Y.

The expression "elongated shape along the transverse Y axis” should be understood to mean that the front application surface has a larger dimension along this transverse Y axis and that its dimensions along the longitudinal X axis and along the antero-posterior Z axis are smaller than along the transverse Y axis. Furthermore, and as seen more specifically in Figure 3, the front application surface 30 advantageously has a circular profile, in other words, the front application surface 30 extends along an arc of a circle, when the main application member 3 is viewed in the plane defined by the longitudinal X axis and the transverse Y axis, or X, Y plane.

Thus, the expression "front application surface 30 which is convex towards the outside when the application member is viewed in the plane defined by the longitudinal X axis and the transverse Y axis" should be understood to mean that the intersection between the front application surface 30 and any plane parallel thereto defined by the longitudinal X axis and the transverse Y axis is a curved segment, in particular a circular segment, which is convex towards the outside of the main application member 3.

Advantageously, the circular profile of the front application surface 30 in the X, Y plane has a radius of curvature of less than or equal to 60 mm, in particular between 30 mm and 50 mm, and in particular approximately 40 mm. Such curvature is particularly advantageous for being able to easily and precisely apply a line of eyeliner composition both on the domed part of the eyelid and also on the hollow parts of the eyelid located in particular at the ends of the eyelid in the region of the inner and outer corners of an eye.

Furthermore, and as can be seen in Figures 1 to 4, the front application surface 30 is substantially flat when the main application member 3 is viewed in the plane defined by the longitudinal X axis and the antero-posterior Z axis, or X, Z plane. In other words, the intersection between the front application surface 30 and any plane parallel to the X, Z plane is a substantially straight line segment.

As a variant, it may be provided that the front application surface 30 is convex towards the outside when the main application member 30 is viewed in the plane defined by the longitudinal X axis and the antero-posterior Z axis, or X, Z plane. Thus, in this variant, the intersection between the front application surface 30 and any plane parallel to the X, Z plane is a substantially curved segment, in particular a circular segment.

As seen in particular in Figures 3 and 4, the front engagement surface 30 extends over a height h along the longitudinal axis X between its first end 37 for attachment to the handle and its second end 38 supporting the front engagement surface 30.

The front application surface 30 further has a width I measured along the transverse Y axis between a first lateral end 31 and an opposite second lateral end 32.

The width I of the front application surface 30 is advantageously between 10 mm and 20 mm and in particular is approximately 15 mm.

Finally, the front application surface 30 has a thickness e measured along the antero-posterior Z axis between a first edge 33 and an opposite second edge 34.

According to an advantageous arrangement of the invention, the thickness e of the front application surface 30 varies as it moves along the transverse axis Y, and is minimum at the first lateral end 31 and at the second lateral end 32. In this way, a main stamping application member 3 is obtained, the front application surface 30 of which is tapered in the direction of its lateral ends 31, 32, making it possible to apply to the eyelid, and in particular to the ends of the eyelid situated in the region of the inner and outer corners of the eye, a line of eyeliner at the tapered end, which contributes to the aesthetic appeal of the resulting make-up. Furthermore, and as will be presented in more detail in the remainder of the present description, by the shape of the front application surface 30 of the main application member 3 which is thinned at the lateral ends 31, 32, it is possible to apply a curved line of eyeliner, which follows the curvature of the eyelid at the base of the eyelashes, formed from multiple adjacent lines deposited by stamping using the application member 3, with an angular displacement around the longitudinal axis X between the adjacent lines, so as to form a contour of substantially continuous curvature, i.e. a contour having substantially no pronounced recesses/angles, in particular at the junction between two adjacent lines.

More specifically, in the embodiments illustrated in the figures, the thickness e of the front engagement surface 30 is zero at the first and second side extremities 31, 32, wherein the first and second edges 33, 34 of the front engagement surface 30 meet at these first and second side extremities 31, 32.

Even more specifically, in the embodiments illustrated in Figures 1 to 11, and as can be seen in particular in Figure 4, the thickness e of the front application surface 30 varies continuously when moving along the transverse Y axis, wherein said front application surface 30 has, in projection in a plane perpendicular to the longitudinal X axis, a substantially oval shape, in particular an ellipsoidal shape.

The maximum thickness of the front application surface, which, in the illustrated embodiments, is midway between the first and second side extremities 31, 32 of the front application surface 30, is between 0.5 mm and 2.5 mm, and is preferably about 1.3 mm.

According to an advantageous arrangement of the invention, the front engagement surface 30 of the main engagement member 3 is extended laterally by lateral engagement surfaces 35, 36 extending substantially perpendicular to the front engagement surface 30.

Like the front application surface 30, the side application surfaces 35, 36 are suitable for being loaded with the cosmetic product P by placing the side application surfaces 35, 36 in contact with the cosmetic product P and for being placed in contact with the skin to deposit by stamping on it a line of cosmetic product P whose shape and contour substantially correspond to the shape and contour of the side application surfaces 35, 36.

Advantageously, the lateral engagement surfaces 35, 36 are concave outwards when the engagement member is viewed in the X, Y plane.

The expression "concave towards the outside when the application member is viewed in the X, Y plane" should be understood to mean that the intersection between the lateral application surfaces 35, 36 and any plane parallel to the X, Y plane is a curved segment, in particular a circular segment, which is concave towards the outside of the main application member 3.

As will be described later herein, the outwardly concave profile of the lateral application surfaces 35, 36 in the X, Y plane makes it possible to easily and accurately apply, by stamping, a line of eyeliner at the base of the eyelashes, in particular in the hollow parts of the eyelid located in the region of the inner and outer corners of an eye.

Preferably, the lateral application surfaces 35, 36 have a circular profile when the main application member 3 is viewed in the X, Y plane, wherein preferably said circular profile has a radius of curvature comprised between 140 mm and 170 mm, in particular about 155 mm. By these arrangements, the curvature of the lateral application surfaces 35, 36 in the X, Y plane is particularly suitable for the defined and precise application of an eyeliner line, in particular in the hollow parts of the eyelid situated in the region of the inner and outer corners of the eye.

Figures 6 and 7 illustrate an applicator for stamping application of a cosmetic product using an applicator member according to a second embodiment not forming part of the invention. This second embodiment of the invention differs from the first in that the lateral application surfaces 35, 36 have a larger dimension along the longitudinal axis X.

Thus, in the first embodiment, the main application member 3 has, along the longitudinal axis X, a height h comprised between 3 mm and 6 mm, for example, approximately 4.5 mm, and, in the second embodiment, the main application member 3 has, along the longitudinal axis X, a height h comprised between 10 mm and 20 mm, for example, approximately 15 mm.

Furthermore, and as can be seen in particular in Figures 1 to 3, the second end 22 of the handle 2 is equipped with a secondary engagement member 4.

This secondary application member 4 has a secondary application surface 40 suitable to be loaded with the cosmetic product P by placing the secondary application surface 40 in contact with the cosmetic product P and to be placed in contact with the skin to deposit by stamping thereon a line of cosmetic product P whose shape and contour substantially correspond to the shape and contour of the secondary application surface 40.

The secondary application surface 40 extends in a plane forming an angle with the longitudinal axis X’ of the handle 2 and has a triangular or teardrop-shaped outer contour.

This secondary application member 4 allows for the stamping application of a line of eyeliner to the outer corner of the eye.

In this way, an applicator 1 is obtained which allows the application by stamping of both a line of eyeliner along the eyelid, at the base of the eyelashes, using the front application surface 30 and the side application surfaces 35, 36 belonging to the main application member 3, and a tail of eyeliner in the outer corner of the eye, using the secondary application surface 40 belonging to the secondary application member 4.

Preferably, the handle 2 and the main and secondary application members 3, 4 of the applicator are made of plastic.

More precisely, the handle 2 is advantageously made of a relatively rigid plastic, especially a thermoplastic material, such as polypropylene (PP), polyethylene (PE), polyamide (PA) or the like. Said relatively rigid plastic may have, for example, a Shore hardness greater than 80 Shore D.

Furthermore, the primary application member 3 and the secondary application member 4 are made of a relatively flexible plastic, such as a silicone, a rubber or a thermoplastic elastomer (TPE). Said relatively flexible plastic may have, for example, a Shore hardness between 20 Shore A and 80 Shore D.

The expression "relatively rigid" should be understood to mean that the plastic from which the handle 2 is made has a greater rigidity than that from which the main engagement member 3 and the secondary engagement member 4 are made. Similarly, the expression "relatively flexible" should be understood to mean that the plastic from which the main engagement member 3 and the secondary engagement member 4 are made has a greater flexibility than that from which the handle 2 is made.

Advantageously, the material from which the handle 2 is made and the material from which the main engagement member 3 and the secondary engagement member 4 are made have a difference in hardness of at least 10 Shore units, better still at least 20 Shore units.

Advantageously, the main application member 3 and the secondary application member 4 are mounted on the handle 2 of the applicator 1 by overmolding.

To this end, the first and second ends 21, 22 of the handle 2 advantageously have protuberances defining hollow portions to promote overmolding attachment of the primary engagement member 3 and the secondary engagement member 4 to the handle 2.

The first end 21 of the handle 2 that receives the main engagement member 3 thus has an arc 210 defining a gap with the main body of the handle 2 into which the constituent material of the main engagement member 3 penetrates during overmolding of the main engagement member 3 onto the handle 2.

The second end 22 of the handle 2 that receives the secondary application member 4 thus has a pin 220 optionally provided with a radial slot that allows to define reliefs to promote the fixing of the secondary application member by overmolding on the second end 22 of the handle 2.

As a variant, the bolt is adapted to be grippingly inserted into a complementary housing provided in the secondary engagement member 4.

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

The present invention also relates to a set, illustrated in Figure 8, comprising an applicator 1 as described above, and a container 5 containing the product P to be applied using the applicator, in the present case an eyeliner composition to be applied to the eyelids.

Next, with reference to Figures 5 and 8 to 11, a method according to the invention will be described for the stamping application of an eyeliner composition onto the eyelids using the applicator as described above.

In a first stage of the process according to the invention, an assembly is provided for packaging and applying the cosmetic product as described above and as seen in Figure 8.

In a second step, at least a portion of the front application surface 30 is loaded with the cosmetic product P to be applied, in the present case an eyeliner composition, placing said portion of the front application surface 30 in contact with the cosmetic product P contained in the container 5.

According to the first gestures of use, the user loads the entire front application surface 30 with the cosmetic product P to be applied, in this case an eyeliner composition, bringing the entire front application surface 30 into contact with the cosmetic product P contained in the container 5.

According to the second gestures of use, the user can load the entire front application surface 30 or only a part of the front application surface 30, for example a central part or a lateral part, in particular a lateral half, of the front application surface, with the cosmetic product P to be applied, in this case an eyeliner composition, by bringing the entire front application surface 30 or only a part of the front application surface into contact with the cosmetic product P contained in the container 5.

In a third step, and as can be seen in Figure 9, the cosmetic product P loaded on the front application surface 30 is applied to an eyelid by placing the front application surface 30 in contact with the eyelid, the transverse axis Y of the application member 3 preferably extending substantially parallel to the eyelash implantation line, and the longitudinal axis X of the application member 3 preferably being placed substantially perpendicular to the surface of the eyelid, to deposit by stamping thereon a line t of cosmetic product P, the shape and contour of which substantially correspond to the shape and contour of the part of the front application surface 30 placed in contact with the eyelid.

In the first gestures of use, the user places substantially the entire front application surface 30 in contact with the skin to deposit by stamping a trace of cosmetic product P whose shape and contour substantially correspond to the shape and contour of the front application surface 30.

Thus, according to this first gesture of use, the application of a stroke of eyeliner t on the eyelid whose shape and contour substantially correspond to those of the front application surface 30 is achieved by placing the product-loaded front application surface 30 in contact with the eyelid, at the base of the eyelashes, with the transverse Y axis of the applicator member 3 extending substantially parallel to the eyelash implantation line and preferably with the longitudinal X axis of the applicator member 3 extending substantially perpendicular to the eyelid, and by rolling the front application surface 30 on the eyelid, by rotating the applicator member 3 about the antero-posterior Z axis, alternately in a first and in a second direction of rotation, as illustrated in Figure 12.

In this Figure 12, the applicator 1 is illustrated in the three successive stamping application positions which make it possible to produce a complete line of eyeliner on an eyelid by the first gestures of use, with the longitudinal axis X1, X2, X3 occupying three successive positions on the eyelid, along the lash line, and extending in each case substantially perpendicular to the eyelid, wherein the front application surface 30 is caused to roll on the eyelid by rotation of the applicator member 3 about the antero-posterior axis Z, alternately in a first and a second direction of rotation, as illustrated by the double arrows in Figure 12.

The outwardly convex shape of the frontal application surface 30 when the applicator member 3 is viewed in the plane defined by the longitudinal X axis and the transverse Y axis advantageously facilitates this rolling movement of the frontal application surface 30 on the eyelid, by rotating the applicator member 3 around the antero-posterior Z axis.

According to the second gestures of use, the user loads all or part of the front application surface 30 with the cosmetic product and places only a part of the front surface 30 that is loaded with product, for example a central part or a lateral part, in particular a lateral half, of the front application surface 30, in contact with the skin to deposit by stamping a trace of a cosmetic product whose shape and contour substantially correspond to the shape and contour of the part of the front application surface 30 placed in contact with the skin.

Thus, according to this second gesture of use, the application of a stroke of eyeliner on the eyelid whose shape and contour substantially correspond to those of the part of the front application surface 30 placed in contact with the eyelid is carried out by placing a part of the front application surface 30 loaded with product in contact with the eyelid, at the base of the eyelashes, with the transverse axis Y of the applicator member 3 extending substantially parallel to the eyelash implantation line, especially with the longitudinal axis X of the applicator member 3 extending substantially perpendicular to the eyelid and preferably without rolling the front application surface 30 on the eyelid, as shown in Figure 13.

In this Figure 13, the applicator 1 is illustrated in the five successive stamping application positions that make it possible to produce a complete line of eyeliner on an eyelid by the second gestures of use, with the longitudinal axis X1, X2, X3, X4, X5 occupying five successive positions on the eyelid, along the lash implantation line, and each time extending substantially perpendicular to the eyelid. Unlike the first gesture of use, in the second gesture of use, the applicator is not rotated about the anteroposterior axis and a user applies the product on the eyelid with a light touch, moving the applicator according to the normal to the eyelid.

In an advantageous arrangement of the process according to the invention, multiple successive steps of applying the loaded eyeliner composition P on the front application surface 30 to the eyelid are carried out to form thereon an eyeliner line along the entire length of the eyelid, at the base of the eyelashes, between the ends of the eyelid located in the region of the inner corner C1 and the outer corner C2 of the eye, as can be seen in Figure 11.

As can be seen in this Figure 11, the eyeliner composition lines P successively deposited on the skin are adjacent to each other and partially overlapped, to jointly form on the skin a continuous curved line T, following the topology of the eyelid at the base of the eyelashes between the ends of the eyelid located in the region of the inner corner C1 and the outer corner C2 of the eye.

Figure 5 illustrates successive applications by stamping three strokes t1, t2, t3 of eyeliner by means of the applicator of Figures 1 to 4 according to the first gestures of use, in which the user loads the entire front application surface with the product P and applies the loaded product on an eyelid by bringing the entire front application surface 30 into contact with the eyelid, at the base of the eyelashes, with the transverse axis Y1, Y2, Y3 of the applicator member 3 extending substantially parallel to the eyelash implantation line and preferably with the longitudinal axis X1, X2, X3 of the applicator member 3 extending substantially perpendicular to the eyelid, and rolling the front application surface 30 on the eyelid, by rotating the applicator member 3 around the antero-posterior axis, alternately in a first and in a second direction of rotation, as illustrated in Figure 12.

According to an advantageous arrangement of the process according to the invention, according to the first or second gestures of use, and as shown in Figure 5, two adjacent lines t1, t2, t3 of the eyeliner composition P successively deposited on the skin are superimposed over a length Lsp1, Lsp2 comprised between 0.5 mm and 5 mm, preferably between 1 and 3 mm, in particular approximately 2 mm.

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

Thus, in the embodiment illustrated in Figure 5, the overlap length Lsp1 between the first line t1 and the second line t2 is measured along the transverse Y2 axis 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 Y3 axis of the third line t3.

Furthermore, and according to another advantageous arrangement of the process according to the invention, the successive steps of applying the eyeliner composition P using the front application surface 30 are performed by imparting an angular displacement a1, a2 about the longitudinal axis X between a first line tn of the eyeliner composition and an adjacent line tn+1.

In this way, and as can be seen in Figure 5, the first line t1 of the eyeliner composition P is deposited on the eyelid by placing the transverse axis Y1 in a first angular orientation around the longitudinal axis X, intended to adapt to the location of the eyelid on which it is desired to apply a first line t1 of the eyeliner composition P.

A second line t2 is then applied by angularly shifting the application member around its longitudinal X axis by an angle a1 and partially overlapping the second line t2 with the first line t1 over an overlap length Lsp1.

A third line t3 is then applied by angularly shifting the application member about its longitudinal X axis by an angle a2 and partially overlapping the third line t3 with the second line t2 over a length Lsp2 of overlap.

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.

However, these overlap lengths Lsp1, Lsp2 may be different without departing from the scope of the present invention, the essential feature being that all the lines form a continuous curved T line, which follows the topology of the eyelid at the base of the eyelashes between the ends of the eyelid located in the region of the inner corner C1 and the outer corner C2 of the eye.

Similarly, in the illustrated embodiment, the angles a1, a2 of displacement about the longitudinal axis X between the transverse axes of the first and second lines t1, t2, on the one hand, and of the second and third lines t2, t3, on the other hand, are equal.

However, the displacement angles a1, a2 may be different without departing from the scope of the present invention, the essential feature being that all the lines form a continuous curved T line, which follows the topology of the eyelid at the base of the eyelashes between the ends of the eyelid located in the region of the inner corner C1 and the outer corner C2 of the eye.

Furthermore, although in the illustrated embodiment three lines t1, t2, t3 are applied to together form a continuous curved T line that follows the topology of the eyelid at the base of the eyelashes between the ends of the eyelid located in the region of the inner corner C1 and the outer corner C2 of the eye, this T line could be produced with more or less than three lines.

In particular, and as seen in Figure 13, the second gesture of use of the applicator member according to the invention imposes a greater number of successive applications to form a complete line of eyeliner at the base of the eyelashes than the first gesture of use.

In the illustrated exemplary embodiments, a complete line of eyeliner at the base of the lashes from the inner corner C1 to the outer corner C2 of an eye is performed in three successive applications when the user adopts the first usage gestures as seen in Figure 12 and in five successive applications when the user adopts the second usage gestures, as shown in Figure 13.

As can be seen in Figure 5, the ellipsoidal shape of the front application surface projected onto a Y, Z plane, combined with the partial overlap of two adjacent lines t1, t2, t3, makes it possible to produce a resulting T line whose contour is curved and continuous, i.e. it has essentially no sharp recesses/angles, in particular at the junction between two adjacent lines.

According to an advantageous arrangement, and as illustrated in Figure 11, the process according to the invention may comprise the additional steps consisting of:

- loading a lateral application surface 35, 36 with the eyeliner composition P to be applied by placing the lateral application surface 35, 36 in contact with the eyeliner composition P contained in the container 5; and

- applying the eyeliner composition P loaded on the lateral application surface 35, 36 onto the skin, in particular at an inner corner C1 of the eyelid, by placing it in contact with the skin, wherein the longitudinal axis X of the application member 3 is preferably positioned substantially parallel to the skin surface, to deposit by stamping thereon a line of eyeliner composition P whose shape and contour substantially correspond to the shape and contour of the lateral application surface 35, 36, wherein said line deposited by the lateral application surface 35, 36 is adjacent to, and partially overlaps with, a line t of eyeliner composition P deposited by the front application surface 30.

Finally, the process according to the invention may advantageously comprise a step of finishing the application of the eyeliner composition on the eyelid, consisting of forming a V-shaped corner at the outer corner C2 of the eye, as illustrated in Figures 10 and 11.

Thus, the process according to the invention advantageously comprises the additional steps consisting of:

- loading the secondary application surface 40 of the secondary application member 4 with the eyeliner composition P to be applied by placing the secondary application surface 40 in contact with the eyeliner composition P contained in the container 5; and

- applying the eyeliner composition P loaded on the secondary application surface 40 on the skin, in particular on an outer corner C2 of the eyelid, by placing it in contact with the skin to deposit by stamping thereon a line ts of eyeliner composition P whose shape and contour substantially correspond to the shape and contour of the secondary application surface 40, wherein said line tss deposited by the secondary application surface 40 is adjacent to a line t of eyeliner composition P deposited by the front application surface 30.

In this way, by means of the application member 3, the applicator 1 and the process according to the invention, it is possible to apply by stamping on the eyelid a line T which follows the topology of the eyelid at the base of the eyelashes between the ends of the eyelid situated in the region of the inner corner C1 and the outer corner C2 of the eye, and whose contour is curved and continuous, i.e. it has substantially no pronounced recesses/angles, in particular at the junction between two adjacent lines deposited successively.

By means of the process according to the invention, the eyes can be completely made up in an easy, ergonomic and precise manner by means of an eyeliner composition comprising the T line extending over the eyelids at the base of the eyelashes between the inner corner C1 and the outer corner C2 of the eye, and also the V corner located at the outer corner of the eyes, by means of successive stamping operations.

Figures 14 to 21 show an applicator 1' for the application by stamping of the cosmetic product P on the skin, in particular for the application of eyeliner on the eyelids, in a second embodiment according to the invention.

In these figures, elements identical or similar to those of the first embodiment of the applicator are designated with the same reference signs, to which the punctuation mark ' is added.

These elements which are common between the first and second embodiments of the applicator according to the invention will not be described again in detail: only the elements which distinguish the second embodiment from the first will form the subject of the following detailed description.

As can be seen in particular in Figures 14, 15, 19 and 20, the applicator 1' comprises a handle 2' extending along a longitudinal axis X' between a first end 21' and an opposite second end 22'.

The first end 21' of the handle 2' is equipped with an engagement member 3' or primary engagement member, and the second end 22' of the handle 2' is equipped with a secondary engagement member 4'.

In the implementation example illustrated in these Figures 14, 15, 19 and 20, this secondary application member 4' is identical to that described in relation to the first embodiment of an applicator according to the invention.

As a variant, the second end 22' of the handle 2' may be provided with an eyeliner application tip, such as a tip made of fibrous material, for example felt, or a tip made of elastomer. Advantageously, said eyeliner application tip is fluidly connected to an eyeliner reservoir integrated in the handle 2' to be supplied with eyeliner, especially by capillary action or by flow.

The main application member 3' is in the form of a tip connected to the first end 21' of the handle 2' which can be manipulated by a user.

The main application member 3' provided for the application by stamping of the cosmetic product P on the skin, in particular for the application of eyeliner to the eyelids, defines a longitudinal X axis, a transverse Y axis perpendicular to the longitudinal X axis and an antero-posterior Z axis perpendicular to the longitudinal X axis and the transverse Y axis.

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

As seen in these figures, the main application member 3' has a front application surface 30' suitable to be loaded with the cosmetic product P to be applied, in this case an eyeliner composition, by placing at least a part of the front application surface 30' in contact with the cosmetic product P, and to be placed in contact with the skin, in this case the eyelids, especially at the base of the eyelashes, to deposit by stamping thereon a line of product P whose shape and contour substantially correspond to the shape and contour of the part of the front application surface 30' placed in contact with the skin.

The main application member 3' has along the longitudinal axis X a first end 37' constituting an end for fixing to the handle 2' and an opposite second end 38' supporting the front application surface 30'. As described in relation to the first embodiment of the applicator 1 not according to the invention, the front application surface 30' has an elongated shape along the transverse axis Y, which is convex outwards when the application member 3' is viewed in the plane defined by the longitudinal axis X and the transverse axis Y.

Similarly, the front application surface 30' further has a width I' measured along the transverse Y axis between a first lateral end 31' and an opposite second lateral end 32'.

The width l' of the front application surface 30' is advantageously between 10 and 20 and in particular is approximately 15 mm.

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 according to the invention has a curved contour defining a concavity C when the application member 3' is viewed in the plane defined by the transverse Y axis and the antero-posterior Z axis.

The curved contour of the 30' frontal application surface in the plane defined by the transverse Y axis and the anteroposterior Z axis extends along a curved Ac axis.

Advantageously, this curved axis Ac forms an arc of a circle preferably having a radius of curvature R less than or equal to 60 mm, in particular between 30 mm and 200 mm.

In the implementation example illustrated in Figures 14 to 21, and as can be seen in particular in Figure 17, the radius R of curvature of the curved axis Ac is approximately 50 mm.

The concavity C defined by the curved contour of the front application surface 30' in the Y, Z plane advantageously has a depth p along the Z axis between 0.2 mm and 1.5 mm. In the implementation example illustrated in particular in Figure 17, this depth p is approximately 0.7 mm.

By these arrangements, the curvature of the front application surface 30' in the plane defined by the transverse Y axis and the antero-posterior Z axis is particularly suitable for improving the ease, ergonomics and precision of the application by stamping of a line of eyeliner at the base of the eyelashes, wherein the concavity C defined by this curved contour adapts to the curvature of the eyelash line, so that the applied line of eyeliner follows this eyelash line as precisely as possible.

Advantageously, in the implementation examples illustrated in Figures 14 to 21, the cross section of the handle 2' in the plane defined by the transverse Y axis and the antero-posterior Z axis also has a curved contour defining a concavity C'. This concavity C' has the same orientation as the concavity C defined by the curved contour of the front engagement surface 30' in this same plane defined by the transverse axis and the antero-posterior axis.

The curved contour of the front engagement surface 30' belonging to the engagement member 3' in the plane defined by the transverse Y axis and the antero-posterior Z axis and 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 X axis and the antero-posterior Y axis. In other words, the curved contour of the front engagement surface 30' belonging to the engagement member 3' in the plane defined by the transverse Y axis and the antero-posterior Z axis and the curved contour of the cross section of the handle 2' in this same plane are centered relative to each other on the Y, Z axes. Preferably, these two curved contours are also centered relative to each other on the longitudinal X axis.

By these arrangements, the handle 2' and the application member 3' of the applicator 1' both have a concave shape of the same orientation along the longitudinal axis X in the plane defined by the transverse axis Y and the antero-posterior axis Z, so that the user determines, in an intuitive and ergonomic manner, how to hold the applicator 1' so as to orient the concavity C of the front application surface 30' of the application member 3' appropriately relative to his or her eyelid, i.e. in the direction of the eye to be made up.

The curved contour of the cross section of the handle 2' in the plane defined by the transverse Y axis and the anteroposterior Z axis advantageously extends along a curved Ac' axis.

This curved axis Ac' advantageously forms an arc of a circle preferably having a radius R' of curvature between 10 mm and 35 mm.

In the implementation example illustrated in Figures 14 to 21, and as can be seen in particular in Figure 18, the radius R’ of curvature of the curved axis Ac’ is approximately 15 mm.

The concavity C' defined by the curved contour of the cross section of the handle 2' in the Y, Z plane advantageously has a depth p' along the Z axis of between 0.4 mm and 3 mm. In the exemplary embodiment illustrated in particular in Figure 17, this depth p' is approximately 0.9 mm.

Thus, the curvature of the 2' handle in the plane defined by the transverse Y axis and the antero-posterior Z axis is more pronounced than the curvature of the 30' frontal application surface in this same plane.

In other words, the radius R’ of curvature of the handle 2' in the plane defined by the transverse Y axis and the anteroposterior Z axis is less than the radius R of curvature of the frontal application surface 30' in this same plane.

The more pronounced curvature of the handle 2' in the plane defined by the transverse Y axis and the antero-posterior Z axis clearly indicates to the user the appropriate orientation for maneuvering and manipulating the applicator 1'.

As seen in particular in Figure 16, the thickness e of the front application surface 30' is substantially constant as it moves along the transverse Y axis, following the curved Ac axis.

The first and second edges 33', 34' of the front application surface 30' meet at the first lateral end 31' and the second lateral end 32', forming a rounded shape.

The front application surface 30' has, in projection onto the plane defined by the transverse Y axis and the antero-posterior Z axis, a substantially oblong curved shape.

In an advantageous arrangement, the first edge 33' and the second edge 34' of the front engagement surface 30' have, in particular at the first lateral end 31' and at the second lateral end 32', an edge protruding from the front engagement surface 30' along the longitudinal axis.

Said edge, the projection distance of which along the longitudinal axis X relative to the front application surface 30' may be comprised, for example, between 0.05 mm and 1 mm, or even 1.5 mm, advantageously makes it possible to create a container for cosmetic product between the front application surface 30' and this protruding edge, thus increasing the quantity of cosmetic product that can be carried in the application member 3' and improving its autonomy, in that the user must refill it with product less frequently. According to an advantageous arrangement, and as can be seen in Figures 19 and 20, each of the lateral application surfaces 35', 36' has a slit 350', 360' in the plane defined by the longitudinal axis X and the transverse axis Y.

The height hf of the application member 3' along the longitudinal axis X is thus reduced in its lateral parts in relation to the height h of its central part. These lateral parts of the application member 3', which have slits 350', 360' perpendicular thereto, thus have greater flexibility, especially in the directions of the longitudinal axis X and the anterior-posterior axis Z, than the central part of the application member 3'.

As can be seen very clearly in Figure 21 which illustrates, in a manner analogous to Figure 5, an eyeliner line T’ obtained after the successive application of three eyeliner lines t1', t2', t3', by using, according to the first gestures of use, an application member 3’ whose front application surface 30’ is convex towards the outside when viewed in the X, Y plane, and which also has a curved contour defining a concavity C when viewed in the Y, Z plane, a continuous, defined and smooth line T’ can be produced, with a relatively pronounced curvature and which follows the topology of the eyelid on which the eyeliner is applied, at the base of the eyelashes.

In one embodiment of the invention, it may be provided that the application member 3, 3', or at least the front application surface 30, 30' of the application member 3, 3', and/or the secondary application member 4, 4', or at least the secondary application surface 40, 40', are flocked.

The application members 3, 3' according to the first and second embodiments can be used with the first or second use gestures.
