Description

Title of the invention: Applicator comprising an application member produced by additive synthesis

The present invention relates to a cosmetic product applicator on the eyelashes and / or eyebrows, in particular a make-up or care product, for example mascara, and the corresponding packaging and application devices. The invention also relates to a process for manufacturing such an applicator and to the associated makeup process.

Technical area

It is known from international application WO 2008113939 a method of manufacturing a cosmetic product applicator on the eyelashes and / or eyebrows by additive synthesis. The applicator has an applicator member having a core and teeth extending from the core. The teeth are devoid of reliefs and each extend in a plane transverse to the longitudinal axis of the core.

The international application WO 2017/098134 discloses a cosmetic product applicator on the eyelashes and / or eyebrows comprising protuberances in the form of a loop extending to the surface of the core and rectilinear protuberances. The latter may have secondary protrusions extending from them transversely to the longitudinal axis of the core.

Summary of the invention

The invention aims to meet this objective and relates, according to one of its aspects, to an applicator of a cosmetic product, comprising an application organ obtained by additive synthesis, the application organ comprising:

[0007] · a core extending along a longitudinal axis, and • a plurality of application elements extending from the core, including application elements each comprising:

· A body of elongated shape, and • at least one protrusion extending laterally from the body at least partially towards a first longitudinal end of the organ

Application, all the protrusions being such that, for any cross section of the protrusion, each point located on the outer surface of the protrusion in this section is connected to at least one point on the outer surface of the protrusion each other cross section taken by progressing from the section towards the distal end of the protuberance (“next” cross section), by a vector oriented perpendicular to the longitudinal axis of the core and / or oriented towards the first longitudinal end of the application body.

By "application elements" is meant individualizable projecting elements, intended to come into engagement with the eyelashes and / or eyebrows.

By “a vector oriented perpendicular to the longitudinal axis of the core and / or oriented towards the first longitudinal end of the applicator member”, it is understood that the vector is defined by a component oriented perpendicular to the longitudinal axis of the core and / or a component oriented towards the first longitudinal end of the applicator member.

"Cross sections of the protrusion" means sections perpendicular to the extension axis of the protrusion.

By “in the direction of the first longitudinal end of the applicator member”, it is understood that • for all the cross sections of the protuberance, progressing from the base of the protuberance towards its distal end, each point of the external surface of the protuberance is connected to at least one point on the outer surface of the protuberance of each following cross section by a vector oriented perpendicular to the longitudinal axis of the core and / or oriented towards the distal end of the organ d 'application or • for all cross sections of the protuberance, progressing from the base of the protuberance to its distal end, each point on the outer surface of the protrusion connects to at least one point on the outer surface of the protuberance each following cross section by a vector oriented perpendicular to the longitudinal axis of the core and / or oriented towards the proximal end of the applicator member.

Thus, all the application elements are devoid of protuberances extending towards the second end of the applicator member and all the protrusions are devoid of portion extending towards the second end of the applicator member relative to at the base of said portion.

The fact that the applicator is obtained by additive synthesis allows it to be obtained in a single step, the various constituent elements of the applicator having come into one with each other without it being necessary to use a mold. This also makes it possible to have new forms of applicator, in particular impossible to produce by injection molding due to the presence of undercuts.

The presence of protrusions on at least some application elements makes it possible to facilitate the loading of the applicator with a cosmetic product, by increasing the surface area of the applicator and by creating reserves of product, in particular at the junction of the protrusions with the corresponding application element. This improves the load of eyelash product during application. This also makes it possible to "raise" the level where the composition accumulates on the applicator part, by providing surfaces adapted to its accumulation at a certain radial distance from the core.

In addition, the fact that the protrusions are as described above limits the extension of the protrusions laterally or to a single side of the brush, which allows to provide if desired free spaces between the elements d application to facilitate the penetration of the eyelashes between them. As a result, the load of eyelashes with product during application is improved while allowing good handling and separation of the eyelashes and smoothing of the product on their surface.

Preferably the application member is in one piece. By "monoblock", it is understood that the applicator member is made in one piece. The applicator member can be made from a single thermoplastic material. As a variant, the applicator member may comprise several materials, in particular parts made of different materials melted together at their junction during their manufacture so as to form only one piece. For example, the core comprises a core made of a flexible material covered with an envelope made of a more rigid material, the two materials being melted together at their junctions.

The applicator may include a rod to which the application member is fixed, in particular having a housing in which is held a tip of the application member. Preferably, the endpiece extends along the longitudinal axis of the core, which can be straight or curved.

Preferably, the applicator is symmetrical about its longitudinal axis.

The applicator may have no plane of symmetry.

The applicator member can be obtained from a pre-established digital model by solidification of a raw material slice by slice from a second longitudinal end of the applicator towards the first longitudinal end of the applicator member, in particular from its distal end to its proximal end or preferably from its proximal end to its distal end. When the first longitudinal end of the applicator member is the distal end, the applicator member can be obtained from a pre-established digital model by solidification of a raw material slice by slice from its end proximal to its distal end and when the first longitudinal end of the applicator member is the proximal end, the applicator member can be obtained from a pre-established digital model by solidification of a raw material cut by slice from its distal end to its proximal end.

The fact that the protrusions are as described above allows, during production by additive manufacturing, in particular by a printing process by Digital Light Processing (DLP), that all the portions of the solidified protrusions slice by edge are attached to the core by the application element. A portion that is not, at a time of the synthesis of the applicator by a DLP printing process, attached to the core could due to the manufacturing process being done in a liquid bath, move, which would not allow a synthesis conforming to the numerical model.

Finally, the presence of at least one protuberance on the body of the application elements makes it possible to benefit from at least one reserve of product distant from a certain radial distance from the core, which makes it possible to load the eyelashes and / or eyebrows without having to engage them deeply within the application member.

Preferably, the applicator member is made of a material chosen from semi-crystalline thermoplastic materials, in particular a polyamide such as Nylon 12. These materials make it possible to obtain parts of good mechanical and thermal resistance.

Alternatively, the applicator member is made of a material chosen from materials which can be polymerized by light irradiation, in particular photo-crosslinkable materials, materials which can be polymerized by catalysis or materials which can be polymerized by the application of heat, in particular thermo materials. -crosslinkable. This allows manufacturing by an additive synthesis process in which the solidification of the material is done by light irradiation, in particular using a laser, by localized catalysis or by localized application of heat.

In another variant, the applicator member is made of a material chosen from ceramics or metals.

Preferably, the applicator member may have an envelope surface of circular section.

The envelope surface can be of any shape. Preferably, the envelope surface is cylindrical.

Alternatively, the section of the envelope surface is of continuously variable dimension along the longitudinal axis of the core, in particular decreasing in the direction of the ends of the applicator member and being able to pass through one or more extrema . This in particular facilitates the application of the cosmetic product to the eyelashes at the corner of the eye. The envelope surface is defined by the distal end of at least part of the application elements. For example, the envelope surface may have a side view of the applicator member with a substantially polygonal, oval, in particular circular, ogival, oblong shape or a peanut shape.

Preferably, the envelope surface is defined by the distal end of the application elements having at least one protuberance.

The core extends along a longitudinal axis.

By "longitudinal axis of the core" is meant the line joining all of the barycenters of the cross sections of the core. The longitudinal axis may be a central axis, or even an axis of symmetry for the core, in particular when the core has a circular cross section or in the general shape of a regular polygon. The longitudinal axis of the core may be straight or curved and may be contained in a plane, which may be a plane of symmetry for some, if not all, of the cross sections of the core. Preferably, the longitudinal axis of the core is rectilinear, and coincides with the longitudinal axis of a rod supporting the application member.

Preferably, the longitudinal axis of the core is rectilinear. Alternatively, this axis may have one or more curvatures.

The core may be, in cross section, of circular or polygonal shape.

The core can be full or hollow.

The core may include longitudinal openings. These allow you to accumulate product. Thus, the autonomy of the applicator and its load capacity in cosmetic product is increased. Openwork can also allow flexibility of the soul.

Preferably, the core has at least one helical groove rotating around the longitudinal axis of the core, preferably at least two helical grooves rotating around the longitudinal axis of the core, opposite and likewise not. Such grooves allow the creation of cosmetic product reserves on the core.

Preferably, the bodies of the application elements having at least one protuberance each have an extension axis:

- extending in a plane transverse to the longitudinal axis of the core, or - inclined at least partially towards the first longitudinal end of the applicator member.

The fact that the bodies of the application elements are not inclined towards the second end of the application member makes it possible to promote the penetration of the eyelashes and / or eyebrows between the application elements of the application member. 'application. This also prevents material from being solidified during additive synthesis of the application member without it being attached to the core by a bridge of material.

Preferably, the application elements comprising at least one protuberance each include a plurality of protrusions extending laterally from the body. This improves the separation of the eyelashes and benefits from several product reserves, especially in height on the application elements.

Preferably, the application member includes application elements without protuberance. The application elements without protuberance are preferably inclined at least partially towards the first longitudinal end of the application member. This makes it possible in particular to limit the presence of space devoid of application element in side view of the applicator, that is to say in view perpendicular to the longitudinal axis of the core.

The application elements without protuberance can be inclined relative to the radial axis of the core at their base at an angle between 0 and 90 °, better between 5 and 30 °, even better between 10 and 20 °.

Alternatively, the application elements without protuberance have any other shape, in particular the shape of a tooth or a V shape. The distal end of the application elements without protuberance can be widened, preferably flattened in a flattening plane transverse to the longitudinal axis of the core. For example, the enlarged end of the body has a disc, cross or V shape.

Alternatively, all the application elements each include:

· An elongated body, and • at least one protrusion extending laterally from the body at least partially in the direction of a first longitudinal end of the applicator member,

All the protrusions being such that, for any cross section of the protuberance, each point located on the outer surface of the protuberance in this section is connected to at least one point on the outer surface of the protuberance in each other cross section taken progressively from the section towards the distal end of the protuberance (“next” cross section), by a vector oriented perpendicular to the longitudinal axis of the core and / or oriented towards the first longitudinal end of the organ d 'application.

Preferably, the row or rows of application elements extend helically around the longitudinal axis of the core by following a helix having the same pitch as the helical groove or grooves and preferably at equal distance of the two helical grooves.

The row application elements can be aligned following the helix defined by the corresponding groove.

The rows of application elements can have an alternation of application elements having at least one protuberance and application elements without protuberance. This allows both good separation of the eyelashes and / or eyebrows, in particular by the application elements without protuberance and a good load of cosmetic product of the eyelashes and eyebrows, in particular by the application elements having at least one protuberance.

As a variant, all of the application elements comprise a body and at least one protuberance as mentioned.

The height of at least one application element, measured from the core, can be between 0.3 mm and 5 mm, or even between 0.5 mm and 3 mm.

"Height of an application element" means the distance measured along the extension axis of the application element between its free end and its base by which it is connected to the core.

Preferably, the height of the application elements having at least one protrusion varies, for example monotonously, when one moves along the longitudinal axis of the core. In a variant, the height of the application elements having at least one protuberance is constant along the longitudinal axis of the core. The height of the application elements having at least one protuberance may decrease in the direction of the distal and proximal ends of the application member.

Preferably, the height of the application elements without protuberance varies, for example monotonously, when one moves along the longitudinal axis of the core. In a variant, the height of the application elements without protuberance is constant along the longitudinal axis of the core. The height of the application elements without protuberance may decrease in the direction of the distal and proximal ends of the application member, which may facilitate the crossing of the wiper member.

Preferably, the distal ends of the applicator elements having at least one protuberance define the envelope surface of the applicator member.

detailed description

FIG. 1 shows a device 1 for packaging and application produced in accordance with the invention, comprising an applicator 2 and an associated container 3 containing a product P to be applied to the eyelashes and / or the eyebrows, for example mascara or a skincare product.

The container 3 comprises, in the example considered, a threaded neck 4 and the applicator 2 comprises a closure cap 5 arranged to be fixed on the neck 4 in order to close the container 3 in a sealed manner in the absence of use, the closure cap 5 also constituting a gripping member for the applicator 2.

The container 3 can also be produced otherwise.

The container 3 also includes a wiping member 6, for example inserted in the neck 4.

The applicator 2 comprises a rod 7 with a longitudinal axis Y, which is connected at its upper end to the closure cap 5 and, at its lower end, to an applicator member 8. The latter comprises a core 10 carrying application elements 18, extending from the core 10 and all around the latter.

This wiping member 6, which can be any, comprises in the example considered a lip arranged to wipe the rod 7 and the application member 8 when the applicator 2 is removed from the container 3. The lip defines a spin orifice 6a of diameter adapted to that of the rod.

The wiper member 6 can be made of elastomer.

The wiping member 6 may include a wiping orifice 6a of circular shape, possibly with slots.

The diameter of the wiping orifice 6a of the wiping member 6 is for example between 2.5 and 6 mm, being for example of the order of 3.5 mm or 5 mm.

The wiper member 6 may optionally have undulations, allowing the wiper orifice to widen more easily when the applicator member 8 passes.

The wiper can still be adjustable, if necessary.

In the example illustrated, the rod 7 has a circular cross section but it is not beyond the scope of the present invention when the rod 7 has a different section, the fixing of the cap 5 on the container 3 can then be carried out other than by screwing, if necessary. The wiping member 6 is adapted to the shape of the rod 7 and to that of the application member 8, if necessary.

Preferably and as in the example considered, the longitudinal axis Y of the rod 7 is rectilinear and coincides with the longitudinal axis of the container 3 when the applicator 2 is in place thereon, but it does not leave the framework of the present invention when the rod 7 is not straight, forming for example an elbow.

The rod 7 may comprise, if necessary, an annular constriction on its portion which comes to be positioned facing the lip of the wiping member 6, so as not to mechanically stress the latter excessively during storage.

The rod 7 to which the applicator member 8 is fixed may be at least partially, in particular entirely, flexible, in particular near the applicator member.

The fixing of the applicator member 8 on the rod 7 can be done by any means and in particular by force mounting, snap-fastening, bonding, stapling or crimping welding, in a corresponding housing provided at the end of the rod 7. The applicator member 8 may comprise, as illustrated in FIG. 2, a nozzle 9 allowing its fixing in a corresponding housing of the rod 7.

An example of an applicator member according to the invention is described in relation to FIGS. 2 to 9 below.

The applicator member 8 has a core 10 and a plurality of applicator elements 18 extending from the core 10.

The core 10 is of elongated shape along a longitudinal axis X. The longitudinal axis X is rectilinear but as a variant could be of another shape, in particular curved. The longitudinal axis X is central, but it could be otherwise.

The length H of the core 10 is, for example, between 15 mm and 27 mm.

As illustrated in FIGS. 8 and 9 in particular, the core 10 has two grooves 16 and 17 each rotating around the longitudinal axis of the core X by following respective helices 13 and 15. The two propellers 13 and 15 are opposite one another relative to the longitudinal axis X and similarly not. The propellers 13 and 15 rotate around the X axis over more than one turn, in particular over more than 6 turns, for example over substantially 8 turns.

The applicator member 8 comprises two rows of applicator elements 18 extending around the core, each following the helical path of one of the two propellers 13 and 15. These rows extend between the two grooves 16 and 17, preferably equidistant from the latter. It could be otherwise. For example, in a variant, the applicator member 8 comprises rows of applicator elements which do not follow the helical path of the grooves 16 and 17. The rows of applicator elements 18 can be helical but s 'extend along the helical grooves 16 and 17.

Alternatively, the core is a solid cylindrical and the rows of application elements 18 extend helically or along the longitudinal axis of the core X.

Each row for example has between 2 and 500 application elements, better still between 5 and 200 application elements.

Each row has for example between 20 and 150 pins, better between 50 and 100 pins.

The application elements are aligned at the base with each other along the corresponding row.

Each row has two kinds of application elements which alternate between them:

Application elements 18a comprising a body 20 and protuberances extending laterally from the body 20, and application elements 18b without protuberance.

The application elements 18b devoid of protuberance may be in the form of pins having a circular section and tapering towards their distal end. As illustrated in FIG. 9, the application elements 18b can be inclined towards the distal end 11 of the application member 8 relative to the radial axis at their base by an angle a of between 5 ° and 25 °, for example substantially equal to 15 °.

The bodies 20 of the applicator elements 18a can be in the form of pins having a circular section and tapering towards their distal end. As illustrated in FIG. 8, the bodies 20 of the application elements 18a can extend along an extension axis C in a plane transverse to the longitudinal axis of the core 10. The extension axes can be inclined relative to the radial axis R at their base by an angle β between 5 ° and 25 °, for example substantially equal to 15 °. The bodies 20 of the application elements 18a can therefore be transverse to the longitudinal axis X of the core and inclined relative to the radial axis R at their base.

The application elements 18a have several protrusions 22 extending along three sides of the body 20. As illustrated in FIG. 8, the application elements 18a may have one or more protrusions 22a and 22b extending each along an extension axis P contained in a transverse plane of the core 10 and one or more protrusions 22c each extending along an extension axis contained in a longitudinal plane of the core in the direction of the distal end 11 of the applicator member 8. The protrusions 22a and 22b can extend on either side of the body 20. All of the applicator elements 18 are devoid of protrusions extending in the direction of the proximal end 13 of the application body 8.

The protrusions 22, as illustrated, are all of substantially identical shape but it could be otherwise.

The protrusions 22a and 22b extend from the body of the same height h while being symmetrical to each other with respect to a median plane M. As can be seen in FIG. 7, the protrusions 22c s' extend at their base from a height on the body different from the protrusions 22a and 22b. The difference in height d on the body 20 of the protrusions 22c and 22a or 22bb can be between 0 and 1.5mm.

In the case where the application elements have several protrusions 22a, respectively 22b, respectively 22c extending on the same side of the body, the latter can be identical and are connected to the body at heights h different from that latest. In the example illustrated, the protrusions 22a or 22b extending on the same side of the body 20 are spaced apart from each other by a height h _a of between 0.05 and 2 mm, better still between 0.1 mm and 1 mm . The protrusions 22c extending on the same side of the body 20 are spaced apart from each other by a height h _c of between 0.1 and 3 mm, preferably between 0.5 and 1 mm. The height h _c is greater than the height h _a .

The height L of the body, measured from the core along the straight part C _a of the axis of elongation C from the base of the application element 20 _p to its distal end 20 _d , can be between 0.2 mm and 5 mm, for example between 0.5 mm and 3 mm.

The extension axes P of the protrusions 22a, 22b and 22c form, for example, as illustrated, all an angle γ with the extension axis C of the body between 45 ° and 135 °, preferably different from 90 °. In the example illustrated, the protrusions extend partially towards the base of the corresponding application element 18a, the angle γ is substantially equal to 65 °.

[0200] Each application element 18a is symmetrical with respect to a median plane M but it could be otherwise.

Preferably, the application elements 18a have protuberances 22 extending in the upper half of the application element so as to constitute product reserves in height.

As illustrated in Figure 10, all the protrusions 22 of the application elements 18a are such that, for all the cross sections T of the protrusion 22, progressing from the base 23 of the protrusion 22 towards its end distal 24, each point of the external surface of the protrusion is connected to at least one point of the external surface of the protuberance of each following cross section by a vector V _p oriented perpendicular to the longitudinal axis X and / or oriented towards l distal end 11 of the applicator member 8. Thus, in the illustrated case, point B ₂ of the external surface of the protuberance 22c of the cross section T ₂ is connected to point B1 of the external surface of the protuberance 22c of the cross section Ti by the vector V _p having a vector component Vpperp perpendicular to the longitudinal axis X and a vector component Vpparorïenté towards the distal end 11 of the applicator member ication 8.

The application elements 18a define, by their distal ends, an envelope surface Si, shown in FIG. 3, in which the application member 18 is inscribed. The envelope surface Si is of substantially cylindrical shape with the exception of its distal end which has a reduced diameter.

The application elements 18b may define by their distal ends an additional envelope surface S ₂ , shown in FIG. 4, inscribed in the envelope surface Si and of the same shape. The distance e between the additional envelope surface S ₂ and the envelope surface Si can be constant, in particular between 0 and 3mm, for example substantially equal to 0.5mm. Thus, the application elements 18b can be smaller than the adjacent application elements 18a, the distance between the distal ends of the adjacent application elements 18a and 18b in projection along an axis transverse to the core 10 being equal to the distance e.

In the embodiment presented above, the protrusions 22 are all of the same shape, but it could be otherwise. For example, the protrusions 22c could have a different shape from the protrusions 22a and 22b, in particular because of their orientations relative to the different core.

FIGS. 11 to 27 illustrate shapes of the protrusions 22c which differ from those of the embodiments of FIGS. 1 to 10.

The protrusions illustrated in Figures 11 to 19 could also extend in a transverse plane of the longitudinal axis C of the different body while remaining oriented laterally to the longitudinal axis X and / or towards the end distal 11 of the applicator member.

As illustrated in Figures 11 to 14, the protrusion 22c can form a beak towards the base 30 or the distal end 32 of the body; the spout can be connected to the core 10 by planar, concave or convex surfaces towards the outside. For example, the protuberance 22c can have two flat surfaces connected to each other and to the body to form a beak oriented towards the base 30 of the body 20, as illustrated in FIG. 11, or oriented towards the distal end 32 of the body, as illustrated in FIG. 12, or the protuberance 22c may have a concave surface and a convex surface to form a beak oriented towards the base 30 of the body 20, as illustrated in FIG. 13, or towards the distal end 32 of the body, as illustrated in FIG. 14.

As illustrated in FIG. 15, the protuberance 22c can be of triangular shape by connecting to the body by one of its edges.

The protrusion 22c can form a boss on the body, as illustrated in FIG. 16.

As illustrated in Figures 17 and 18, the protuberance 22c can form a hook oriented towards the base 30 of the body 20, as illustrated in Figure 19, or towards the distal end 32 of the body, as is illustrated in figure 18.

The protrusion 22c can be in the form of a loop extending in a plane transverse to the axis C, as illustrated in FIG. 19.

As illustrated in Figures 20 to 22, the protrusion 22c may include an enlarged end 24 in front view and / or in top view, flattened or not, oriented perpendicular to the axis C, as illustrated in the figure 20, or forming an angle with the latter, as illustrated in FIG. 21.

The protrusion 22c may have a curved extension axis P. The protrusion 22c can then extend at its end laterally to the longitudinal axis X, as illustrated in FIG. 23.

The protrusion 22c can form a loop extending in a plane transverse to the extension axis C, as illustrated in FIG. 24.

FIG. 25 represents a variant of protuberance 22a or 22b extending partially towards the distal end 11 of the applicator member. The protrusion 22a has a curved extension axis so that its distal end is oriented towards the distal end 11 of the applicator member. In this embodiment, the application elements 18a can be devoid of protuberances 22c extending from their base towards the distal end 11 of the application member.

In the embodiment presented above, the application elements 18a have protuberances 22 extending in two different transverse planes of the extension axis C, but it could be otherwise. For example, the application elements could only have one or more protuberances 22c as illustrated in FIGS. 11 to 22, or protuberances 22a and 22c only, or have protuberances 22 extending in three different transverse planes as illustrated in FIG. 49, or present one or more protrusions oriented along a plane transverse to the extension axis C forming a non-zero and non-perpendicular angle with the longitudinal axis X of the core as illustrated in Figures 47 and 48.

In the embodiment presented above, the application elements 18a have several protrusions 22 extending one above the other on the body, but it could be otherwise. The application elements 18a could only have a protuberance in a transverse direction of the body 20.

In the embodiment presented above, the body 20 of the application elements is in the form of pins extending along a rectilinear axis C. However, it could have any other form achievable by additive manufacturing, for example

[0220] - a flattened shape as illustrated in FIGS. 32, 36, 37, 40, 41, 43 and 45,

a shape widened at its distal end in the direction transverse to the longitudinal axis X, as illustrated in FIGS. 26 to 29, 32 and 39, and / or at its base, as illustrated in FIGS. 32, 36-38, 41, 43 and 45, - a shape extending along a curved extension axis C, as illustrated in FIGS. 30 and 42, 44 and 46, for example in the form of a hook at its distal end as illustrated in FIGS. 42 and 44, - a form having one or more elbows, as illustrated in FIGS. 28, 29, 31 to 38 and 45,

- a shape extending for example in the form of a V, as illustrated in FIG. 38, or of an X or having a V or an X at the end, as illustrated in FIGS. 28 and 29,

- a shape extending in the shape of an arrow, the point being oriented towards the distal end 32 of the body, as illustrated in FIG. 39, or towards the base 30, as illustrated in FIG. 40, and / or

- a form forming a loop, as illustrated in FIGS. 30 and 46.

As illustrated in Figures 30, 33 to 35 and 46, the body 20 may be full or hollow.

Preferably, the body 20 of the application elements 18a is such that, for all the cross sections T of the body, progressing from the base 30 of the body 20 towards its distal end 32, each point of the external surface of the body is connected to at least one point on the external surface of the body of each following cross section by a vector V _c oriented perpendicular to the longitudinal axis X and / or oriented towards the distal end 11 of the core 10. The body therefore does not have a portion extending towards the proximal end 13 of the core. The invention is not limited to the embodiments described above. Other forms of protuberances and of bodies are possible and other distribution of protuberances on the body also. The embodiments described above are combinable, unless the opposite is explicitly mentioned. The applicator member may comprise only one kind of applicator elements comprising at least one protuberance. The bodies of the application elements may not all be of the same shape.

In the embodiment described above, the application elements and the protuberances are devoid of portions extending towards the proximal end 13 of the core and at least one protuberance extends at least partially towards the distal end 11 of the applicator member. As a variant, the application elements and the protuberances are devoid of portions extending towards the distal end 11 of the application member and at least one protuberance extends at least partially towards the proximal end 13 of the 'implementing body.

The applicator member 8 can be manufactured using a device for manufacturing by additive synthesis from a digital model of the applicator member 8.

The digital model faithfully represents Application Organ 8 in three dimensions and can be generated using computer-aided design software such as SolidWorks 3D.

As illustrated in Figures 50a-f and 51, the manufacturing device 50 may include a printing medium 51, a powder material distributor 53 intended to deliver a layer of powder material 63 on the printing medium 51 , a first agent dispenser 55 for delivering one or more coalescing agents 65 to the layer of powder material 63, a second agent dispenser 57 for providing one or more coalescing modifier agents 67 and an energy source 59 .

During manufacture, the powder material dispenser 53 deposits a first layer of powder material 63 over the entire surface of the print medium 51 as illustrated in FIG. 50a by moving the material distributor 53 along the Yd axis. One or more coalescing agents 65 and / or coalescing modifiers 67 are then deposited on parts of the layer 63, as shown in FIG. 50a, by moving associated distributors along the axis Yd. The parts of the layer 63 on which the agents 65 and the modifiers 67 are deposited are determined according to the digital model formed previously.

Once the coalescing agents 65 and coalescing modifiers 67 are deposited, the latter at least partially penetrate the layer 63, as can be seen in FIG. 50b. Finally, energy is applied to the entire layer 63 using the source 51. The application of this energy makes it possible to cause the parts on which the coalescing agent (s) 65 have been applied to melt at least partially, which allows, once the layer has cooled, to solidify the melted parts as illustrated in FIG. 50c. The modifiers 67 make it possible to have edges of the merged zones free by preventing the fusion of the peripheral zones. After the layer of material 63 has been treated, as described above, a new layer 73 of pulverulent material is deposited on the layer 63 previously treated as illustrated in FIG. 50d. The process explained above can then be repeated to generate the three-dimensional applicator layer by layer as illustrated in Figures 50d-f.

During manufacture, the support 51 moves along the z axis so that as new layers of material are deposited, a predetermined space is maintained between the surface of the deposited layer most recently and the distributors 55 and 57. As a variant, the support 51 is not mobile along the axis z and the distributors 55 and 57 can be mobile along this axis.

Preferably, the applicator member 8 is manufactured using this device from its proximal end 13, that is to say from that intended to be attached to the rod 7, at its distal end 11. The reverse is also possible.

A manufacturing process of this type, suitable for producing the applicator, is described in particular in international applications W02015106816.

Alternatively, the applicator member 8 is manufactured using a different additive synthesis manufacturing device, in particular by light irradiation of a photo-crosslinkable material, as illustrated in FIGS. 52 and 53 In the example considered, the manufacturing device can comprise a light source 40, a tray 42 disposed above the light source 40 and a support 46. The tray 42 is transparent at least partially to the radiation emitted by the light source. . It contains a photo-crosslinkable liquid material 44.

During production, the light source 40 is controlled according to the digital model to crosslink the liquid material 44 in a formation zone between the support 46 and the plate 42, according to a pattern depending on the digital model. The crosslinked portions of the liquid material 44 are solid. Before manufacture, as illustrated in FIG. 52, the support 46 is immersed in the liquid material 44 and the formation zone is in contact with the support 46, so that the liquid material 44 is crosslinked on the support 46 while being attached to it. latest. During manufacture, as illustrated in FIG. 53, the support 46 is moved away from the light source 40 at the speed of manufacture of the applicator member 8, so that the crosslinked parts are produced in successive layers, each reticulated layer attached to the previous one.

The tray 42 may have a surface 48 between the support 46 and the light source 40 in fluid communication with a source of polymerization inhibitor, in particular a source of oxygen. The polymerization inhibitor makes it possible to maintain liquid material 44 in liquid form, by preventing its polymerization by light irradiation, in a fluid zone of non-zero thickness. This fluid zone extends from the surface 48 towards the formation zone and allows the circulation of the liquid towards the formation zone. Preferably, the fluid zone has a height of between 10 μm and 100 μm.

The interface between the fluid zone and the formation zone may not be straightforward but may be formed from a polymerization gradient. In this case, the support 46 is moved continuously and the irradiation by the light source 40 is continuous.

Preferably, the applicator member 8 is manufactured using this installation from its proximal end 13 to its distal end 11. The reverse is also possible.

After the manufacture of the applicator member 8, the latter is detached from the support 46 and heated to stiffen and smooth the structure.

A manufacturing process of this type, suitable for producing the applicator, is described in particular in international applications WO2014126830 and WO2014126837.

As a variant, the applicator member 8 is manufactured using a device for manufacturing by different additive synthesis, in particular by printing by filament deposition (EDM), stereolithography (SLA) or selective laser sintering ( SLS).

The invention is not limited to the exemplary embodiments described above.

The device may include a product reservoir and the applicator is mounted by its proximal end 13 on the reservoir. In this case, the applicator has a hollow core and openings allowing the cosmetic product to be supplied to the applicator.
