Description

Title of the invention: Fluid or pasty product applicator device and fluid or pasty product dispenser comprising such a device. technical field

[0001] The invention relates to the field of applicators for fluid or pasty cosmetic products such as mascara.

[0002] The invention relates more specifically to a device for applying a fluid or paste-like product and a dispenser for a fluid or paste-like product comprising such a device. Prior art

[0003] In order to apply fluid or paste cosmetic products, such as mascara, it is known to use fluid or paste product dispensers.

[0004] Such dispensers for fluid or paste products generally comprise: - a cosmetic product applicator assembly including a cap, a rod and an applicator device, the cap having a skirt, suitable for cooperating with a neck of a bottle, and the rod extending from the skirt and having a second end on which the applicator device is mounted, - the bottle including the neck, the skirt being shaped to cooperate with said neck, the bottle being intended to contain the cosmetic product and - a wringer arranged in said bottle to wring the applicator device and thus ensure good distribution of the cosmetic product on the applicator device when removing the applicator assembly.

[0005] To ensure proper application of the cosmetic product to keratin fibers or to a portion of the epidermis and / or mucous membrane, the applicator device comprises a longitudinal core and a plurality of pins arranged in rows along at least a portion of the core's length, each pin extending longitudinally from the core. The pins capture the cosmetic product and deliver it to the keratin fibers or to the portion of the epidermis and / or mucous membrane when the applicator device is pressed against said fibers or the portion of the epidermis and / or mucous membrane. However, this delivery of the cosmetic product is not always optimal, and the person using the dispenser often needs to apply the product in several steps to achieve the desired and even application.

[0006] To optimize this application, various options are possible. For example, document EP 3468412 B1 proposes structuring the pins, either by creating cavities along the pin or protrusions, in order to define along these The last of the reservoirs are capable of capturing cosmetic product. The nubs allow for the capture of more cosmetic product, so this optimization allows for the application of more product in a single pass.

[0007] It is also known from document EP 3261487 B1 to optimize the shape of the bristles in order to guide the keratin fibers during product application. This document demonstrates, in Figures 16 to 17B, the creation of a loop (open or closed) on a distal portion of the bristle in order to guide the keratin fibers during product application. Such bristles allow for a more homogeneous application of cosmetic product onto the keratin fibers.

[0008] However, while these solutions make it possible to improve either the amount of cosmetic product applied to the keratin fibers or the homogeneity of this application, there is currently no satisfactory solution which makes it possible to apply an appropriate amount of cosmetic product homogeneously to the keratin fibers.

[0009] Similarly, none of these solutions allows for the application of a cosmetic product in the form of "tubing" (more commonly known by its English name) in a single application. Indeed, while the pin shapes described in document EP 3261487 B1 may allow for application in the form of "tubing," the quantity of product they allow is insufficient for application along the entire length of the keratin fibers. Thus, there is currently no applicator device that allows for the single application of a cosmetic product in the form of "tubing." Description of the invention

[0010] The invention aims to remedy at least in part the above disadvantages and thus aims to provide an applicator device allowing optimized application of fluid or paste cosmetic product on keratin fibers.

[0011] The invention also aims to provide an applicator device which allows the application of a cosmetic product in the form of a "tube" by "sheathing" this over the entire length of a keratin fiber in one go.

[0012] The invention relates to this purpose an applicator device (10) for applying a fluid or paste-like product to keratin fibers or to a portion of epidermis and / or mucous membrane, comprising: - a longitudinal core extending along a longitudinal axis XX; - a plurality of pins arranged in at least a first row along at least a portion of the length of the core, each pin extending longitudinally from the core, or from a possible extension of the core, presenting a portion proximal to the core, or to said extension, and a distal portion extending from the proximal, the distal part representing between 10 and 90% of a total length of said picot.

[0013] At least a portion of the spikes includes a distal portion comprising at least a first portion of enlarged cross-section curved with respect to the proximal portion with an enlargement along an enlargement line included in a plane perpendicular to the longitudinal axis XX so as to delimit a first surface for retention of the fluid or paste product and for guidance of keratin fibers during the application of said fluid or paste product.

[0014] With this type of spike, the first portion of the distal part combines both a reservoir shape, through the orientation of the retention surface which tends to retain the product when the applicator device is removed from the product bottle, and guidance of the keratin fibers within said reservoir, through the curved shape of the retention surface. Thus, with this guidance of the keratin fibers in a cosmetic product reservoir, optimized application of the cosmetic product is achieved.

[0015] Moreover, with this curved shape and the quantity of product which is stored by the retention surface, it is easy to obtain a product application in the form of "tubing".

[0016] The first portion of the curved enlarged section may have the curvature centered around an axis parallel to the enlargement line D.

[0017] This curvature of the first portion of the enlarged section can be complex; for example, the first portion may have two distinct curvatures across its width. It should also be noted that an enlargement line according to the invention can be defined with respect to a plane perpendicular to the longitudinal axis XX. Equivalently, and as shown in the figures in this document, it is also conceivable that such an enlargement line could be defined as a line perpendicular to a plane J parallel to the longitudinal axis of the web, also known to those skilled in the art as the "parting plane." Thus, according to an alternative and equivalent definition, the enlargement line is a line perpendicular to the parting plane, which is parallel to the longitudinal axis XX of the web.

[0018] It should be noted that such a widening along a widening line means that the first portion of the stud, in a longitudinal direction z of the stud and in an orthogonal projection of the portion onto a plane defined by the widening line and the longitudinal direction z, has a width that is increased relative to the proximal portion. More specifically, as can be seen in Figures 8D, 14C, 16C, 19C, and 20C, the first portion has a significantly greater width in such a projection than the proximal portion. This maximum width of the first portion in this same orthogonal projection can be greater than at least one and a half times that of the proximal part, or even two times, or three times that of the proximal part.

[0019] According to one possibility of the invention, the proximal portion of the spike has a face extending along the joint plane and therefore parallel to the longitudinal axis XX of the core.

[0020] Each stud, or at least a portion of the studs, may further comprise a second portion of an enlarged cross-section curved with respect to the proximal portion, with an enlargement along the line of enlargement so that this second portion delimits a second surface for the retention of the fluid or paste product and for guiding keratin fibers during the application of said fluid or paste product.

[0021] Such a second portion of the curved enlarged section allows, in addition to providing a second storage area for the fluid or pasty product, to form between the two portions a guide for the keratin fibers.

[0022] For each spike, at least a portion of the spikes, the first portion and the second portion face each other over at least part of their width so as to delimit between them a basin extending longitudinally along the line of widening to retain fluid or pasty product and for the guidance of keratotic fibers.

[0023] Such a limitation of a cup allows an optimized guiding function of keratin fibers.

[0024] For each pin of at least one part of the pins, one of the first and second portion can widen from the proximal part in a single direction of the widening line, the other of the first and second portion widening from the proximal part in two directions of the widening line.

[0025] In this way, the portion widening along the two directions of the widening line presents, along the widening line, a greater product storage capacity than that of the other portion while maintaining a good guiding function of the keratin fiber.

[0026] For each pin of the at least part of the pins, the first portion and the second portion both widen from the proximal part in two directions of the line of widening.

[0027] In this way, the spike offers maximum storage capacity in fluid or pasty product.

[0028] Each stud, or at least a portion thereof, may further comprise a third portion of an enlarged cross-section curved along the line of enlargement so that this third portion delimits a third and fourth surface for retaining the fluid or paste-like product and for guiding keratin fibers during the application of said fluid or paste-like product, the third portion being disposed between the first portion and the second portion so as to delimit between the first and third portion a first guiding basin for keratotic fibers and between the second and third portion a second guiding basin.

[0029] With such a third portion, each spike has maximum storage capacity while offering two guidance pathways for the keratin fibers. Thus, it is possible to obtain optimal product application with a reduced number of spikes.

[0030] At least two pins of the at least part of the pins and of the first row can be connected to each other at their distal part.

[0031] In this way, the bristles in the same row, linked together, are joined and made more rigid, while still being able, due to the elasticity of their proximal portion 111, to partially deform to conform to the implantation of the eyelashes. This results in better adhesion of the bristles during the application of the fluid or paste product to the keratin fibers.

[0032] The at least two pins of the at least a part of the pins and of the first row can be connected to each other by one end of the first portion of one and one end of the second portion of the other.

[0033] The pins of at least a part of the pins can be arranged according to at least the first row and a second row, said first and second rows being separated from each other by a third row of pins of a type distinct from the pins of at least a part of the pins, said pins of the third row extending preferentially longitudinally from the core with a decreasing cross-section.

[0034] In this way, the applicator device combines the benefits of the pins according to the invention with those of the prior art pins.

[0035] The pins of at least a part of the pins are arranged according to at least the first row and a second row successive to each other.

[0036] In this way, it is possible to align the pins of the first and second row in order to provide optimal guidance of the keratin fibers.

[0037] The pins in the second row may have an orientation reversed from those in the pins in the first row.

[0038] With such an inverted orientation, the spikes present their first portions and their possible second and third portions aligned in order to offer an application of fluid or pasty product on the keratin fibers and a guidance of the latter particularly homogeneous; since each of the two sides of the keratin fibers benefits from an application of product with a first portion and with possible second and third portions.

[0039] The core may have at least one longitudinal extension and at least one first row of studs may extend along said longitudinal extension, said longitudinal extension preferably being an arch extending along the rest of the core and being connected to the latter at at least one end of the core.

[0040] In this way, with such an extension, the spikes according to the invention can be arranged according to this extension with a shape, that of the extension, conforming best to the shape of the keratin fibers or of the portion of epidermis and / or mucous membrane on which the fluid or pasty product is to be applied.

[0041] The first portion may have a first and second lateral sub-parts having a distinct curvature from each other, the first and second lateral sub-parts being preferably separated from each other by a plane parallel to the longitudinal axis of the core.

[0042] The first portion may have a curvature along an axis substantially parallel to the line of widening or making an angle of less than 45° with the line of widening.

[0043] In this way, it is possible to optimize the shape of the spike according to the invention for the storage and / or guidance of keratin fibers.

[0044] The invention further relates to a cosmetic product dispenser, comprising: - a cosmetic product applicator assembly comprising a cap, a rod and an applicator device according to the invention, the cap having a skirt, adapted to cooperate with a neck of a bottle, and the rod extending from the skirt and having a second end on which the applicator device is mounted, - the bottle comprising a neck, the skirt of the rod / cap element being shaped to cooperate with the neck of the bottle, - a wiper arranged in said bottle.

[0045] Such a cosmetic product dispenser benefits from the advantages associated with the applicator device equipping its applicator assembly and therefore allows an optimized application of fluid or pasty product. Brief description of the drawings

[0073] Detailed description of particular embodiments

[0074] Fig. 1 illustrates a cosmetic product dispenser 1 to allow the application of fluid or paste cosmetic products on keratin fibers or on a portion of epidermis and / or mucous membrane, said dispenser 1 comprising an applicator device allowing optimized application of cosmetic products, particularly on keratin fibers.

[0075] Such a cosmetic product dispenser 1 comprises: - a cosmetic product applicator assembly 10, 20 comprising a cap 211, a rod 212 and an applicator device 10, the cap 211 having a skirt, adapted to cooperate with a neck 21 of a bottle 20, and the rod 212 extending from the skirt 211 and having a second end on which the applicator device 10 is mounted, - the bottle 20 comprising the neck 21, the skirt 111 being shaped to cooperate with the neck 21 of the bottle 20, - a 40-inch wringer arranged in said bottle 20.

[0076] According to the configuration illustrated in [Fig.1], the hood 211 and the rod 212 form a hood / rod element 210.

[0077] The invention specifically relates to the cosmetic product applicator device 10, the rest of the dispenser 1, not having any specificity related to the invention, is not described further in this document.

[0078] Figures 2A to 2C illustrate an applicator device 10 according to a first embodiment of the invention. This applicator device 10 is, in this first embodiment, as well as those of the other embodiments described in this document, independent of the rest of the applicator assembly 10, 20. The applicator device 10 can be mounted, for example, by press fitting, screwing, or elastic snap-fitting. Alternatively, the applicator device 10 can be formed integrally with the end of the rod 212.

[0079] According to the invention, the applicator device 10 comprises: - a longitudinal core 100 extending along a longitudinal axis XX, - a plurality of pins 110A, 110C arranged in at least a first row 120A, 120C along at least a portion of a length of the core 100, each pin 110A, 110C extending longitudinally from the core 100 by presenting a proximal portion 111 to the core 100, and a distal portion 115 extending from the proximal portion 111, the distal portion 115 representing between 10 and 90% of a total length of said pin 110A, 110C.

[0080] According to the invention, at least a portion of the pins 110A, 110C comprise the distal portion 115 having at least a first portion 116 of enlarged cross-section curved relative to the proximal portion 111 with an enlargement the along an expansion line D included in a plane perpendicular to the longitudinal axis XX so as to delimit a first retention surface of the fluid or pasty product and of guidance of keratin fibers Cl during the application of said fluid or pasty product.

[0081] The web 100 may have an elongated shape. The web 100 may have a constant or variable cross-section along its length. In most common embodiments, the cross-section is either constant or decreases from a proximal end intended to engage with the rod 212 to a free distal end. Generally, the web 100 is overall cylindrical, preferably of revolution about the longitudinal axis XX. Thus, the cross-section of the web 100 may be circular, polygonal, oval, or other. It may be asymmetrical. The web 100 may be solid or hollow. Those skilled in the art will choose the most suitable web 100 based on economic and / or technical constraints. Cylindrical in the present embodiment, other possible shapes are shown later in this document with reference to Figures 20A to 21.

[0082] The pins 110A, 110B, 110C extend from the core, arranged in several rows 120A, 120B, 120C, in the present embodiment, 16 rows. It may be noted that, according to one possibility of the invention, the applicator device 10 according to this first embodiment comprises an alternation of rows 120A, 120C of pins 110A, HOC according to the invention and rows 120B of conventional pins 110B, i.e., elongated pins having a decreasing cross-section. Thus, we can see in particular that certain pins 110A, HOC according to the invention are arranged according to a first row 120A and a second row 120C, the said first and second rows 120A, 120C being separated from each other by a third row 120B of pins 110B of a type distinct from the pins according to the invention, the said pins 110B of the third row extending preferentially longitudinally from the core 110 by presenting a decreasing section (that is to say by presenting a conical shape)..

[0083] As shown in Figures 3A to 3C, the pins 110A according to the invention are in a two-part form, with the proximal part 111 at the core 100, and the distal part 115 extending from the proximal part 1. In the present embodiment, the proximal part 111 has a substantially constant rectangular cross-section along the pin 110A. According to the invention, the distal part has the first portion 116 of enlarged cross-section curved relative to the proximal part 111 with an enlargement along an enlargement line D situated in a plane perpendicular to the longitudinal axis XX.

[0084] According to an alternative definition and as shown in [Fig. 3A], the widening line D is a line perpendicular to a plane J parallel to the axis The longitudinal plane of the core, also known to those skilled in the art as the "parting plane." In the present embodiment, the parting plane J corresponds to one of the faces of the proximal portion 111. According to one possibility of the invention, in this first embodiment, the first portion 116 presents its widening relative to the first portion 111 along only one direction of the widening line D. Thus, according to the present embodiment, the entire pin is presented along only one side of the parting plane J, with neither the proximal portion 111 nor the distal portion 115 extending to the other side of the parting plane J.

[0085] It should be noted that with such a widening along a widening line D, the first portion 115 of the pin 110A, in a longitudinal direction z of the pin and in an orthogonal projection of the portion onto a plane defined by the widening line D and the longitudinal direction z, exhibits an increasing width. More specifically, as shown in [Fig. 3A], the first portion 115 has a significantly greater width in such a projection compared to the proximal portion. This maximum width of the first portion in this same orthogonal projection can be at least one and a half times that of the proximal portion, or even two or three times.

[0086] Figures 3B and 3C show the curvature C of the first portion 116 of the distal part 115 of the spike 110A. The curvature C of the first portion 116 is centered around an axis parallel to the widening line D. This curvature C tends to shift the first retention surface of the spike 110A from a transverse orientation with respect to the longitudinal direction z of the spike 110A to an orientation parallel to this longitudinal direction. In this way, with such a direction tending to be parallel to the longitudinal direction z of the spike 110A, the first retention surface is able to resist the wiper 40 during the removal of the applicator device 10 from the bottle in order to maintain a reserve of product.

[0087] It is this capacity to retain the cosmetic product P and to apply it to keratin fibers (particularly eyelashes) that is shown in Figures 4A to 4C. Indeed, these figures show that when the person using the applicator device 10 brings the applicator device 10 close to their eyes E and eyelashes Cl in a typical orientation (the longitudinal axis XX parallel to the horizontal of the face), the eyelashes Cl naturally settle into the guide formed by the curvature of the first portion. As shown in Figures 4B and 4C, the retention surface allows the cosmetic product to be stored in the space defined by the curvature of the first portion. Since this quantity of product is greater than that allowed by the prongs of the prior art, a pass of the applicator device allows a larger quantity of cosmetic product to be applied.

[0088] It should also be noted, as shown in Figures 4B and 4C, that such guidance in a product reservoir area can also allow product application in the form of "tubing", which is not generally the case with prior art pins.

[0089] According to one embodiment reproduced in the present embodiment, this guidance can be optimized by an arrangement of the pins 110A, 11 OC in successive rows of pins 120A, 120C according to the invention, the pins of the second row HOC having an orientation inverted from the pins of the preceding first row 110A. Thus, taking the example of the pins 110A, 110C of the first and second rows 120A, 120C, the pins 120B of the second row 120C have an orientation corresponding to an axial symmetry of the pins 120A of the first row 110A around an axis perpendicular to the longitudinal axis XX and passing through the proximal part 111 of the pin 110A.Thus, if we take two pins 110A, 110B from the first and second rows 120A, 120C respectively, substantially aligned with each other (along a direction perpendicular to the longitudinal axis XX, the two pins exhibiting a slight offset), the curvatures of the first retention surfaces will form a guide in which the keratin fibers Cl can slide and become loaded with cosmetic product. This alignment is particularly visible in [Fig. 5B], which illustrates an applicator device 10 according to a variant of the first embodiment.

[0090] Thus, Figures 5A and 5B illustrate an applicator device 10 according to a variant of the first embodiment. An applicator device 10 according to this variant differs from an applicator device 10 according to the first embodiment in that it comprises only pins 110A, HOC according to the invention distributed in two rows 120A, 20C arranged on one face of the core 100.

[0091] Whether it is the applicator device 100 according to the first embodiment or according to its variant, it can be manufactured either by injection molding, by addition of material such as three-dimensional printing or stereolithography, from a wide variety of possible materials and hardnesses. Preferably, the applicator device can be made by injection molding of a thermoplastic material, a thermoplastic or vulcanizable elastomer having antimicrobial and / or antibacterial properties, such as those taught in US document 2017 / 130027 A1.

[0092] Figures 6A to 6C illustrate a pin 110A of an applicator device 10 according to a second embodiment. Such an applicator device 10 according to this second embodiment is distinguished by the fact that the first portion 116 has a greater curvature than the pins 110A according to the first embodiment.

[0093] Thus the applicator device 10 according to this second embodiment differs from the applicator device 10 according to the first embodiment by the shape of the first portion 116.

[0094] As can be seen in Figures 6A and 6C, the 110A pin according to this second embodiment has a first portion with a greater curvature C than that of a 110A pin according to the first embodiment, and extending over a greater height. Thus, the 110A pin according to this second embodiment has a larger retention surface and therefore allows for greater storage of cosmetic product than a 110A pin according to the first embodiment.

[0095] Figures 7A to 7C illustrate a pin 110A of an applicator device 10 according to a third embodiment in which the first portion 116 has an enlargement including a hollow. An applicator device 10 according to this third embodiment differs from an applicator device according to the first embodiment in that the first portion 116 of the pins 110A according to this third embodiment has a different shape from that of the pins 110A according to the first embodiment.

[0096] It can indeed be seen in [Fig.7A] that a pin 110A of an applicator device 10 according to this third embodiment has a first portion 116 which, starting from the proximal part 111, has: - a first portion of height over which it widens along the first direction of the widening line D, - a second section of height over which it narrows, - a third section of height over which it widens again, - a fourth portion of height on which it has a narrowing to define the top of the spike.

[0097] With such an intermediate narrowing, the bristle 110A according to this third embodiment has a retention surface comprising an end sub-portion capable of flexing relative to the rest of the retention surface, thereby facilitating the reception of the eyelash Cl when the applicator device 10 is used to apply cosmetic product to the eyelashes Cl of a person using said device. It should also be noted that such a bristle 110A has a shape resembling that of a leaf.

[0098] Figures 8A to 8D illustrate the pins of an applicator device 10 according to a fourth embodiment in which the pins 110A, HOC according to the invention comprise a distal portion having a second portion 117. An applicator device 10 according to this fourth embodiment differs from an applicator device 10 according to the first embodiment in that its pins 110A, HOC according to the invention present a second portion 117 and in that the pins arranged of pins 110A, HOC according to this fourth embodiment.

[0099] The 110A studs according to this fourth embodiment comprise a distal portion 115 which, in addition to the first portion 116, includes a second portion 117. In accordance with the principle of the invention, the second portion also has a curved, enlarged cross-section relative to the proximal portion 111, with an enlargement along the enlargement line D such that this second portion defines a second surface for retaining the fluid or paste-like product and for guiding keratin fibers during the application of said fluid or paste-like product. Furthermore, unlike the first portion 116 of the 110A studs according to the first embodiment, the first and second portions 110A according to this fourth embodiment enlarge along both directions of the enlargement line D.

[0100] In the present embodiment, the first and second portions respectively have a first and second curvature C, C' each along an axis of curvature substantially parallel to the line of widening D.

[0101] As can be seen in Figures 8A to 8D, in this fourth embodiment, for the pins 110A according to the invention, the first portion 116 and the second portion 117 face each other across their width so as to define between them a basin extending longitudinally along the widening line D for retaining fluid or pasty products and for guiding keratotic fibers. It should also be noted that the first and second portions 116, 117 respectively have a first curvature C and a second curvature C' which are opposite each other and facing each other to form the first and second retention surfaces and define between them the basin extending longitudinally along the widening line D.

[0102] Figures 9A to 9C illustrate an applicator device 10 according to a fifth embodiment in which the second portion 117 of the pins 110A, 110C according to the invention widens only in one direction of the widening line D. An applicator device 10 according to this fifth embodiment differs from an applicator device 10 according to the fourth embodiment in that the second portion 117 of the pins 110A, 110C according to the invention widens only in one direction of the widening line D. It will also be noted, as shown in Figures 10A to 10C, that while the majority of the pins according to the invention conform to the present embodiment and have the configuration illustrated in Figures 10A to 10C, the pins arranged at the distal free end of the core 100 have a conformation conforming to the first embodiment and illustrated on figures 3A to 3C.

[0103] As shown in [Fig.1OA], a pin 110A according to this fifth embodiment differs from a pin 110A according to the fourth embodiment in that the second portion 117 widens life-to-life of the proximal part 111 only in one direction of the widening line D. Thus, in this fifth embodiment, the second portion 117 extends only on one side of the joint plane J.

[0104] In the present embodiment, as can be seen in [Fig. 10A], the pins 110A according to the invention have the first portion 116 and the second portion 117 facing each other over the width of the second portion 117 and therefore over a part of the width of the first portion 116.

[0105] It can also be seen in Figures 9A to 9C that in the present embodiment, although, as in the first embodiment, the pins 110A, 110C of successive rows 120A, 120C of pins according to the invention have an inverted orientation, unlike those of the first embodiment, the pins of these two rows are aligned, thus ensuring the formation of a guide for the eyelashes formed by the

[0106] Figures 1 IA and 1 IB illustrate an applicator device 10 according to a variant of the fifth embodiment having a conformation similar to the variant of the first embodiment illustrated in Figures 5A and 5B. Thus an applicator device 10 according to this variant differs from an applicator device 10 according to the fifth embodiment in that it comprises only pins 110A, HOC according to the invention distributed according to two rows 120A, 120C arranged on one face of the core 100.

[0107] Figures 12A to 12C illustrate a pin 110A of an applicator device 10 according to a second variant of the fifth embodiment in which the pins 110A according to the invention have a first portion 116 which, extending in both directions of the widening line D, has a reduced width compared to the second portion 117. Thus, the applicator device 10 according to this second variant of the fifth embodiment differs from an applicator device 10 according to the fifth embodiment in that each of these pins 110A according to the invention has a first portion 116 which, extending in both directions of the widening line D, has a reduced width compared to the second portion 117.

[0108] As can be seen in [Fig. 12A], the width of the first portion 116 extending from the joint plane J along the same line of widening as the second portion 117, and therefore opposite the latter, has a particularly reduced width. Thus, in the present variant of the fifth embodiment, the basin formed between the first and second portions 116, 117 is particularly narrow.

[0109] Figures 13A to 13D illustrate an applicator device 10 according to a sixth embodiment in which the pins 110A according to the invention comprise a distal part having a third portion 118. An applicator device 10 according to this sixth embodiment differs from an applicator device 10 in that the pins according to the invention comprise a distal part 115 having a third portion 118 and in that the core 100 has at its distal free end only pins according to the prior art.

[0110] Figures 14A to 14C illustrate a 110A spike according to this sixth embodiment, and Figures 13C and 13D show a close-up and a close-sectional view of the applicator device according to this sixth embodiment. These figures show that a 110A spike according to this sixth embodiment comprises a distal portion having, in addition to first and second portions 116, 117, a third portion 118. The third portion 118 of the 110A spikes of this embodiment is a portion with an enlarged cross-section curved along the enlargement line D such that this third portion 118 delimits a third and fourth surface for retaining the fluid or paste-like product and for guiding keratin fibers during the application of said fluid or paste-like product.The third portion 118 is arranged between the first portion 116 and the second portion 117 so as to delimit between the first and third portions 116, 118 a first guiding basin for keratotic fibers and between the second and third portions 117, 118 a second guiding basin.

[0111] In the present embodiment, the third portion 118 has a first and second curvature C*, C” centered around an axis parallel to the widening axis and with respect to the first and second portions 116, 117 respectively. To do this, the third portion 118 has, from the proximal part 111 and along a line perpendicular to the widening line D, a section which reduces and ends with a peak of the pin 110A.

[0112] Figures 15A to 15C illustrate an applicator device according to a variant of this sixth embodiment in which the pins 110A, HOC according to the invention in the same row 120A, 120B are connected to each other. An applicator device 10 according to this variant of the sixth embodiment differs from an applicator device 10 according to the sixth embodiment in that the pins 110A, HOC according to the invention in the same row 120A, 120B are connected to each other.

[0113] It can indeed be seen in particular in [Fig. 15C] that in the present embodiment, two successive pins 110A, 110a of the same row 120A are connected to each other by their first and second portions 116, 117 respectively. In this way, the pins 110A, 110a of the same row 110A, HOC being connected together, They are joined together and made more rigid while being able, due to the elasticity of their proximal portion 111, to partially deform to fit the implantation of the eyelashes.

[0114] Figures 16A to 16C illustrate the pins of an applicator device 10 according to a seventh embodiment in which the pins 110A, 110a of the same row are connected in pairs. An applicator device 10 according to this seventh embodiment differs from an applicator device according to the fourth embodiment in that the pins 110A, 110a of the same row are connected in pairs and have a reversed orientation so as to be connected together by their first portion 116, 116a.

[0115] As can be seen in [Fig. 10A], a pin 110A, 110a according to this seventh embodiment has a conformation similar to that of a pin 110A according to the fourth embodiment. The two successive pins 110A, 110a of the same row 120A thus have an inverted configuration and are connected to each other by their first portion 116, 116a of their distal part 115, 115a, the proximal parts 111, 111a remaining disjoint. The second portions 117, 117a of these two pins 110A, 110a are oriented opposite to each other. Thus the curvatures C, c of the first portions 116, 116a of the two successive pins 110A, 110a are opposite each other, while the curvatures C', c' of the second portions 117, 117a of the two successive pins 110A, 110a are opposite each other.

[0116] In the present embodiment, the two pins 110A, 110a of such a pair of pins 110A, 110a, in order to allow the formation of such a link, have their proximal part 111 brought closer to those of the pins of the pairs that follow them in the same row 120A. With such a link between their first portions 116, 116a, the two pins 110A, 110a together have a shape similar to that of a pin 110A according to the sixth embodiment.

[0117] Of course, while the pins of the present embodiments have relatively simple shapes, the enlargement of the first portion 116 and of the possible second and third portions 117, 118 and of the proximal part 111 of the pins 110A, 110C, 110A can be made more complex without departing from the scope of the invention, provided that the distal part comprises a first portion 116 with an enlarged cross-section that is curved relative to the proximal part 111, with an enlargement along the line of enlargement. Figures 18A to 19D illustrate such examples of shapes.

[0118] Thus, figures 17A to 17D illustrate a stud 110A according to a variant of the fifth embodiment. An applicator device 10 according to this variant differs from an applicator device 10 according to the fifth embodiment in that the proximal part has a curved cross-section and in that the first portion has an asymmetrical shape with respect to the joint plane J.

[0119] [Fig. 17A] shows that the proximal portion extends from the web 100 with a variable cross-section, comprising a first sub-section with a decreasing cross-section, then a second sub-section with an increasing cross-section, and finally a third sub-section with a decreasing cross-section. The first portion 116, as shown in [Fig. 8C], exhibits an asymmetry with respect to the joint plane, the left portion (in [Fig. 18C]) being smaller than the right-hand section.

[0120] Identical to Figures 17A to 17D, Figures 18A to 18D illustrate a stud 110A according to another variant of the fifth embodiment. An applicator device 10 according to this variant differs from an applicator device 10 according to the fifth embodiment in that the proximal part has a curved cross-section extending on both sides of the parting plane and in that the first portion 116 has an asymmetrical shape with respect to the parting plane J.

[0121] According to the principle of the invention, the first portion 116 and the possible second and third portions 117, 118, have an enlarged curved section with respect to the proximal part 111. This curvature can be homogeneous over the entire width of said portion 116, 117, 118, for example around an axis of curvature parallel to the line of enlargement D, or vary along the width of the pin 110A according to the invention.

[0122] Such a possibility is illustrated by a first variant of the applicator device 10 according to the fourth embodiment of the invention shown in Figures 19A to 19E. An applicator device 10 according to such a first variant differs from an applicator device 10 according to the fourth embodiment in that the pins 110A according to the invention each comprise a first and a second portion 116, 117 each comprising a first and second lateral sub-parts 1161, 1162, 1171, 1172 having a distinct curvature from one another, the first and second lateral sub-parts 1161, 1162, 1171, 1172 being delimited from one another by the joint plane J which is parallel to the longitudinal axis XX of the core 100.

[0123] As can be seen in Figures 19B, 19C, and 19E, each of the first and second lateral sub-parts 1161, 1162, 1171, 1172 of the first and second portions 116, 117 has a distinct curvature Cl, C'1, C2, C'2, each centered around a distinct axis of curvature Acl, Ac2, Ac3, Ac4. It should be noted that, according to the present variant, unlike the other embodiments and variants described above, these axes Acl, Ac2, Ac3, Ac4 form an angle with respect to the widening line D and are not parallel to it. Thus, according to the present variant, the axes of curvature Acl, Ac2, Ac3, Ac4 of the first and second lateral sub-parts 1161, 1162, 1171, 1172 of the first and second portion 116, 117 form an angle of 30° with respect to the widening line D.

[0124] More generally, each curvature Cl, C'1, C2, C'2 presented by one of the portions 116, 117 of the distal part of a pin 110A according to the invention can be according to an axis substantially parallel to the widening line D or making an angle of less than 45° with the widening line D.

[0125] It can be seen that with such distinct curvatures Cl, C'1, C2, C'2 of the first and second lateral sub-parts 1161, 1162, 1171, 1172 of the first and second portions 116, 117, in the present embodiment, the basin delimited by the first and second portions 116, 117 has a funnel shape for the keratin fibers, whether they arrive from one side or the other of the notch. Therefore, in addition to optimized guidance, such a funnel shape facilitates the application of cosmetic products in the form of a "tube" by "sheathing" them along the entire length of a keratin fiber.

[0126] In the same way as for the application device 10 according to this first variant of the fourth embodiment, it is also conceivable that the distal part 115 of a pin 110A has a curvature extending in a direction opposite to the longitudinal direction 7 of the pin 110A. With such a curvature, the pin 110A according to the invention may have one of its portions which extends at least in part downwards, i.e. towards its proximal portion 111.

[0127] In order to illustrate such a possibility, figures 20A to 20E show a pin 110A according to a second variant of the fourth embodiment presenting such a configuration. An applicator device 10 according to this second variant of the fourth embodiment differs from an applicator according to the first variant of the fourth embodiment in that the first lateral sub-parts 1161, 1171 of the first and second portion 116, 117 have a curvature Cl, Cl' whose axis of curvature Acl, Ac3 is oriented towards the proximal portion 111, i.e. towards the "down" of said pin 110A, and the axes of the second lateral sub-parts 1161, 1171 of the first and second portion 116, 117 are oriented substantially perpendicular to the proximal portion 111, i.e. to the "horizontal" of said pin 11OA.It can be seen that a stud 110A according to the invention of this second variant of the fourth embodiment has a noticeable crosswise orientation with respect to the joint plane J. Indeed, according to this variant, the first and second portions 116, 115, and the recess which it delimits, have an orientation forming an angle of 30° with respect to the direction perpendicular to the joint plane J, whereas in the embodiments and variants described above, apart from the first variant of the fourth embodiment, the first portion 116 and the possible second and third portions 117, 118 have an orientation perpendicular to the joint plane J.

[0128] In a manner identical to the first variant of the fourth embodiment, the first and second portion 116, 117 of each pin 110A according to the invention have a first and second lateral sub-part 1161, 1162, 1171, 1172. As shown in Figures 20B and 20C, the axis of curvature Acl, Ac3 of the first lateral sub-parts 1161, 1171 of the first and second portions 116, 117 has an angle of less than 90° (here between 50° and 90°, or even between 60° and 80°) with respect to the longitudinal direction z of the pin 110A towards the proximal part 111. The axis of curvature Ac2, Ac4 of the second lateral sub-parts 1162, 1172 of the first and second portions 116, 117 has an angle of 90° with respect to the longitudinal direction z of the pin 11 IA. Moreover, as shown in [Fig.20E], these same axes of curvature Acl, Ac2, Ac3, Ac4 of the first and second sub-parts 1161, 1162, 1171, 1172 have an angle of 30° with respect to the joint plane J.

[0129] Similarly, if the pins 110A according to the invention can have shapes other than those described in the various embodiments described above, the configuration of the applicator device 10 itself and the arrangement of the pins 110A, 110B, 110C on the core 10 can be different without departing from the scope of the invention. Figures 21A to 22 illustrate such a possibility.

[0130] Thus, figures 20A to 20E illustrate an applicator device 10 according to a variant of the fifth embodiment. An applicator device 10 according to this variant of the embodiment differs from an applicator device 10 according to the fifth embodiment in that the core has a circular arc cross-section comprising a convex face 101 and a concave face 102, and in that the concave face has only prior art studs.

[0131] As can be seen in Figures 20A to 20C, the convex face 101 of the core has a configuration similar to that of the applicator device 10 according to the fifth embodiment, while the concave face 102 has five rows of prior art pins (i.e., with a generally conical shape). It should be noted that in the present variant, the core has a constant cross-section over most of its length.

[0132] Figure 22 illustrates an applicator device 10 according to another variant of the fifth embodiment. An applicator device 10 according to this other variant differs from an applicator device 10 according to the fifth embodiment in that the core has a circular arc cross-section comprising a convex face 101 and a concave face 102, in that the concave face has only prior art studs and in that the concave face 102 has, in addition to a lateral concavity as is the case for the previous variant, a longitudinal concavity.

[0133] Thus, in addition to the differences presented by the previous variant of the fifth embodiment, the core according to this other variant has a lateral section that varies along its entire length so as to exhibit a longitudinal concavity. Thus, the core 100 has, at its concave face 102 and its end proximal to its distal free end, a lateral section which decreases and then increases in a curved shape.

[0134] It should also be noted that while in all the embodiments and variants described above the core 100 is monolithic, it is also conceivable, without departing from the scope of the invention, that the core 100 may include extensions, as is the case in the possibility not included in the scope of the invention shown in Figures 21A to 21F. Such extensions may be longitudinal and preferably arches extending along the rest of the core 100, connected to it at at least one end of the core 100, or even at both. In such a configuration, the pins 110A, 110B according to the invention may be arranged along this extension in an arrangement similar to those described in the embodiments / variants shown in connection with Figures 2 to 20.

[0135] If, of course, within the framework of the present invention, the curved shape of the first portion 116 of the distal part 115 of the studs according to the invention makes it possible to offer storage of cosmetic product while offering guidance of keratin fibers, in accordance with figures 21A to 21F, it is possible to obtain an approaching advantage by providing on the core 110 or on several extensions thereof, surface structures.

[0136] It can indeed be seen in Figures 23A to 23F that an applicator device according to the present possibility not included according to the invention comprises: - a longitudinal 100 core extending along a longitudinal axis XX; - a plurality of pins 110 arranged according to at least a first row 120, each pin 110 extending longitudinally from the core 100, or from one of the extensions 105A, 105B, 105C, of ​​the core 100, presenting a part proximal to the core 100, or to said extension 105A, 105B, 105C.

[0137] In accordance with this possibility not included in the scope of the invention, the core 100 and its extensions 105A, 105B, 105C have, along at least a portion of the rows 120 of studs 110 they comprise, a surface structure 130, 130A, 130B, 130C in the form of successive depressions 131, 131A, 131B, 131C along said portion of the corresponding row 120A of studs 110A, two successive depressions 131, 131A, 131B, 131C being connected to each other by an edge extending in a direction (D) contained in a plane perpendicular to the longitudinal axis XX so as to provide guidance for keratin fibers (C) during the application of said product fluid or pasty.

[0138] More specifically, it can be seen that the structures 130, 130A, 130B, 130C have a structuring pitch that is a multiple of that of the pins 110A of the corresponding row 120A, the structures 130, 130A, 130B, 130C having in the configuration illustrated in Figures 21A to 21F a pitch twice that of the pins 110A of the corresponding row. In this same configuration, the edges of the structures are aligned with one pin 120A on two of the corresponding row, each pin corresponding to an edge extending from said edge.

[0139] It can also be seen that in the configuration illustrated in Figures 21A, 21F, for each structure 130A, 130B, 130C, the corresponding pins 110 extend from said structure 130A, 130B, 130C with a substantially identical extension length, such that the pins 110 corresponding to the edges and those corresponding to the bottoms of the basins have different apparent heights relative to the longitudinal axis D. Thus, in [Fig. 21C], the pins 110 corresponding to the bottoms of the basins have a reduced apparent height relative to the longitudinal axis XX compared to those corresponding to the edges.

[0140] According to the configuration of the present embodiment not included in the invention, the web 100 has a first face 101 and a second face 102 opposite the first face 101. The first face 101 of the web 100 has longitudinal extensions 105A, 105B, 105C, while the second face 102 has no such extensions. The extensions 105A, 105B, 105C arranged on the first face 101 have surface structures 130A, 130B, 130C, and the second face 102 also has surface structures 130.

[0141] As shown in Figures 21D and 21E, the core 100 more precisely has three longitudinal extensions 105A, 105B, 105C, arches, and, for each of these arches 105A, 105B, 105C, the row 120A of pins 110A and the corresponding structure 130A, 130B, 130C extend along said arch. Such longitudinal extensions 105A in the form of arches extend along the entire length of the core 100, being connected to it at both ends of the core 100. Of course, alternatively, without departing from this possibility, each of the extensions can be connected to only one of the two ends of the core 100.

[0142] According to the present configuration illustrated in Figures 21D and 21F, each surface structure 130, 130A, 130B, 130C is separated from the surface structure 130, 130A, 130B, 130C which succeeds it along a perimeter of the core 100 by a longitudinal portion 135 not provided with a surface structure. Such a longitudinal portion 135 of the core 100 not provided with surface structuring separating two surface structurings 130, 130A, 130B, 130C is presented in the context of the present configuration of the possibility not included in the scope of the invention in the form of a hollow of the core 100 vis-à-vis the two surface structurings 130, 130A, 130B, 130C which it separates.

[0143] Therefore, an applicator device according to this possibility not included in the scope of the invention can be defined by means of the following independent characteristics or according to the indicated dependency:

[0144] Feature 1: Applicator device 10 for applying a fluid or paste-like product to keratin fibers or to a portion of epidermis and / or mucous membrane, comprising: - a longitudinal core extending along a longitudinal axis XX; - a plurality of 110 pins arranged in at least one first row, each pin extending longitudinally from the core, or from a possible extension of the core, presenting a portion proximal to the core, or to said extension,

[0145] in which the core, or possible extension of the core, has along at least a part of said first row 120 of studs, a surface structure 130, 130A, 130B, 130C in the form of successive cups 131 along said part of the first row 120 of studs 110, two successive cups 131 being connected to each other by an edge extending along a direction D included in a plane perpendicular to the longitudinal axis XX so as to provide guidance for keratin fibers Cl during the application of said fluid or paste product.

[0147] Feature 3: Applicator device according to feature 2 of the first possibility not included in the scope of the invention, in which the structure 130, 130A, 130B, 130C has a pitch twice that of the pins 110 of the at least one row 120 and in which the edges of the structure are aligned with one pin 120 on two of the at least one row 120, each pin corresponding to an edge extending from said edge.
