Description

Description

Title of the invention: Spiral cosmetic applicator

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.

We know from international application WO 2016/050790 a cosmetic product applicator comprising a molded application member comprising a core and application elements extending from the core, the core comprising at least two grooves helical extending along the longitudinal axis of the core.

Application W02008 / 113939 describes an applicator of a cosmetic product manufactured by additive synthesis having a plurality of grooves extending helically around the core in less than one turn.

There is a need to further improve the applicators for the application of a product, in particular mascara, on the eyelashes and / or the eyebrows, in order to improve their performance and, if necessary, allow the obtaining special makeup effects.

Summary of the invention

The invention aims to meet this objective and relates to, according to one of its aspects, an applicator of a cosmetic product on the eyelashes and / or the eyebrows comprising a monoblock application member in at least a non-thermoplastic material, the applicator member comprising:

• a core extending along a longitudinal axis, the core comprising at least one helical groove extending along the longitudinal axis around the latter and forming more than one turn around the longitudinal axis of the core, • at least one row of application elements extending from the core helically around the longitudinal axis of the core, along the helical groove, in particular parallel to the latter.

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

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. Alternatively, this axis may have one or more curvatures.

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 invention allows to obtain, on the application member, in particular along the groove, at least one zone forming a reservoir, not emptied of its content during the extraction of the applicator, thus providing after wringing a surplus of product over the entire length of the core and on all sides. This surplus product allows, from the first application, a significant and satisfactory load of eyelash and / or eyebrow product.

The groove forms a twist on the core. During makeup, the groove gradually empties of its content. The eyelashes and / or eyebrows are thus suitably covered with product without the user having to reload the applicator too frequently by reintroducing it into the container.

We can play on the depth of the grooves to adjust the level of product load of the applicator after passing through the wiper member.

The fact that the groove and the row of application element makes more than one turn around the longitudinal axis of the core makes it possible to have an abundance of application elements around the core allowing good lash load.

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 end piece extends along the longitudinal axis of the core.

Preferably, the applicator has no plane of symmetry.

Preferably, the application member is obtained by additive synthesis. 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.

The applicator member can be obtained from a pre-established digital model by solidification of a raw material section by section from one end to the other of the application member, in particular from its end distal at its proximal end or preferably from its proximal end to its distal end.

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.

As a variant, 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 application of heat, in particular heat-crosslinkable materials. 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.

As a variant, 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 application 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.

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

The soul 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 two helical grooves rotating around the longitudinal axis of the core over more than one turn, opposite and likewise not the two grooves being preferably parallel with respect to one another to the other. Such grooves allow the creation of cosmetic product reserves on the core.

Preferably, the or each helical groove forms a plurality of turns around the longitudinal axis of the core, in particular between 2 and 60 turns, better between 3 and 40 turns over the entire length of the member. application.

Alternatively, the core is cylindrical.

The application elements can be in the form of pins or teeth.

By "teeth" is meant application elements having at least one flattened cross section. The teeth can be as described in patent applications FR 3006566 and FR 3004905.

The application elements can each be full or hollow.

Preferably, the row of application element forms a plurality of turns around the longitudinal axis of the core, in particular between 2 and 60 turns, better between 3 and 40 turns over the entire length of the enforcement body. Such a quantity of turns allows the applicator member to have an aspect supplied with applicator elements and gives the impression that the applicator elements are arranged in a random manner.

The or each row can have a number of application elements between 2 and 500 elements, better still, between 5 and 300.

The application elements may extend in at least two helical rows around the longitudinal axis of the core, in particular in the case where the core has at least two grooves, the rows possibly being parallel to the grooves .

Preferably, the application elements of each row have bases aligned with each other along a helix parallel to the groove or grooves.

The applicator member may include a row of applicator elements extending along the groove.

Preferably, the consecutive application elements of a row are all spaced by the same distance, defined between the axes of extension of two consecutive application elements at their base, between 0.1 mm and 5 mm, better between 0.5 mm and 1 mm.

Preferably, the application elements extend in one or more helical rows forming turns around the longitudinal axis of the core, and the application elements which extend from adjacent turns the along the longitudinal axis of the core do not overlap at their bases, when the applicator member is viewed from the front, that is to say along its longitudinal axis.

Preferably, the application elements each extend along an axis of extension perpendicular to the longitudinal axis of the application member and / or towards a first longitudinal end of the application member, especially the distal end.

The application elements can be of the same shape or of different shapes.

The application body can include two kinds of application elements. Preferably, the applicator member comprises first applicator elements in the form of pins and second applicator elements of a shape different from the first applicator elements, in particular in the form of teeth, of a loop and / or comprising one or more surface reliefs, for example one or more protrusions and / or an enlarged head. Preferably, the application elements of each kind are all oriented in the same way with respect to the radial axis of the core at their base.

The or each row of application elements can have an alternation of first application elements and second application elements. This allows both good separation of the eyelashes and / or eyebrows, in particular by the pins, and a good load of cosmetic product from the eyelashes and eyebrows, in particular by the application elements having at least one protuberance.

Alternatively, each row of application elements has only one kind of application element, the adjacent rows of application elements having different application elements, different or not. Preferably, the application elements are all oriented in the same way with respect to the radial axis of the core at their base.

Preferably, the second application elements each comprise a body and one or more protrusions extending from the body.

The body of the second application elements can extend along an axis of extension, straight or not. The extension axis of the body of the second application elements may have a curved end portion, in particular in the form of a hook. The hook preferably extends perpendicularly to the longitudinal axis of the core or towards the first end of the applicator member.

The body of the second application elements may have an enlarged distal end. The widened distal end is preferably flattened according to a flattening plane. The flattening plane of the widened distal end is preferably a plane transverse to the longitudinal axis of the core. For example, the enlarged end of the body has a disc, cross or V shape.

The enlarged distal end may have a rounded shape at least outward. For example, the distal end may be disc-shaped or umbrella-shaped. Alternatively, it may have a head having edges oriented towards the outside, chamfered in order to limit the projecting corners towards the outside. This makes it possible to have a distal end devoid of projecting elements, which makes possible contact of the applicator member with the eyelids softer. This can only reassure the user and encourage him to approach the application member as close as possible to the eye, which makes it possible to apply the cosmetic product to the base of the eyelashes, or encourage him to exercise stronger pressure with the applicator member on the eyelashes and / or eyebrows, which allows a better load of cosmetic product on the eyelashes.

The enlarged distal end may be full.

Alternatively, the enlarged distal end is hollow. Its hollow appearance can give the application elements a certain flexibility. It also makes it possible to accumulate product by surface tension and thus to increase the autonomy of the applicator and / or to increase the carrying capacity of the applicator, without losing the capacity for separation and combing. Eyelash. The hollow in the distal end may have an opening to the outside.

Preferably, the widened distal ends of the second application elements are all solid, or the widened distal ends of the second application elements are all hollow.

At least one protuberance can extend from the distal half of the body of the second application element. This allows to have a reserve of product in height on the application element, that is to say at a non-zero distance from the soul, which makes it more easily accessible to the eyelashes and / or eyebrows.

Preferably, the protrusions extend along axes of extension forming at their base a non-zero angle with the axis of extension of the body of the corresponding application element, in particular forming an angle between 45 and 90 °, preferably not perpendicular to the extension axis of the corresponding body, better between 60 and 75 °. The protrusions can be oriented radially outwards, or preferably towards the longitudinal axis of the applicator member. This can facilitate the penetration of the eyelashes between the application elements and improve the attachment of the eyelashes by the protrusions, which can facilitate the smoothing of the product on their surface.

The protrusions each extend along a straight or curved extension axis.

At least two protrusions of a second application element, preferably of each second application element, can extend along axes of extension located, at the base of the protrusions, in different planes containing l longitudinal axis of the body. These planes can form an angle between 0 and 180 ° between them (limits excluded), preferably between 45 and 125 °.

At least two protrusions of a second application element, preferably of each second application element comprising protrusions, can extend from opposite faces of the body.

At least two protrusions of a second application element, preferably of each second application element, can extend along extension axes located at the base of the protrusions, in the same longitudinal plane of the body.

At least two protrusions of a second application element, preferably of each second application element, can extend from the body at different heights thereon relative to its base. The two protrusions extending at different heights on the body can extend along extension axes located at the base of the protrusions in the same longitudinal plane of the body or in different longitudinal planes.

The second application elements may each comprise at least three protuberances, one of which extends progressing towards one end of the application member and the other two extend while progressing laterally with respect to the soul and extending from opposite sides of the body.

The second application elements can form a loop with or without surface reliefs. The loop can be connected to the core by two ends spaced from each other.

The loop can be opened or closed.

By "open loop" it should be understood that the outline of the loop has an opening forming an opening. This can be positioned at a non-zero distance from the core, for example at the level of the central portion, so as to separate the application element into two separate parts each connected to the core by one of the two feet. connection. The opening could be positioned elsewhere, for example at the connection to the core so that the application element is connected to the core by a single foot.

The fact that the loop is open can allow eyelash penetration through the opening and / or give more flexibility to wringing.

The opening may have a width less than or equal to 0.3 mm, better than 0.2 mm, even better than 0.1 mm.

Preferably, the second application elements are each symmetrical with respect to a median plane. The second application elements may or may not have an axis of symmetry.

Preferably, the second application elements extend in a plane transverse to the longitudinal axis of the core while being inclined at their base relative to a radius extending from the core, in particular by forming an angle between 0 and 90 °, better between 5 and 30 °, even better between 10 and 20 °. This makes it possible in particular to limit the presence of space devoid of an application element, in particular in front view of the applicator, that is to say in view along the longitudinal axis of the core.

Preferably, the second application elements are perpendicular to their base at the surface of the core from which they extend.

Alternatively, the second application elements each have an extension axis inclined at least partially towards the same 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 first application elements are preferably inclined at least partially towards the same longitudinal end of the application member.

The first application elements 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 °. This makes it possible in particular to limit the presence of space devoid of an application element, in particular in front view of the applicator, that is to say in view along the longitudinal axis of the core.

Preferably, the first application elements are of circular or polygonal cross section.

The first elements of application can extend along a straight line of extension or not. Their distal end may be curved and have a hook.

Alternatively, the first application elements have any other shape, in particular the shape of a tooth or a V shape. The distal end of the application elements devoid of protuberance can be widened, preferably flattened according to 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.

The height of at least one application element, measured from the core, can be between 0.2 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 second application elements varies, for example monotonously, when one moves along the longitudinal axis of the core. Alternatively, the height of the second application elements is constant along the longitudinal axis of the core. The height of the second application elements may decrease towards the distal and proximal ends of the application member.

Preferably, the height of the first application elements varies, for example monotonously, when one moves along the longitudinal axis of the core. In a variant, the height of the first application elements is constant along the longitudinal axis of the core. The height of the first application elements can decrease towards the distal and proximal ends of the application member, which can facilitate the passage of the wiper member.

Preferably, the distal ends of the second application elements define the envelope surface of the application member.

Preferably, the distal ends of the first application elements define a secondary envelope surface inscribed in the envelope surface of the application member. The secondary envelope surface can be spaced from the envelope surface of the applicator member, in cross section, by a constant distance.

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 wring the rod 7 and the applicator 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 attachment of the applicator member 8 to the rod 7 can be done by any means and in particular by force fitting, snap-fastening, gluing, 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 will now be described in relation to FIGS. 2 to 9.

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.

As a variant, 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 has, for example, between 2 and 500 application elements, better still between 5 and 200 application elements.

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 protrusions 22 extending laterally from the body 20, and • application elements 18b in the form of pins.

The applicator elements 18b have a circular section and taper towards their distal end. As illustrated in FIG. 9, the application elements 18b can all be inclined towards the distal end 11 of the application member 8 with respect to a radius at their base, at the same angle a between 0 ° and 90 °, better between 5 and 30 °, even better between 10 and 20 °, for example substantially equal to 15 °.

The bodies 20 of the applicator elements 18a may 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 gitudinal axis Ion of the core 10. The extension axes can all be inclined relative to the radial axis R at their base by the same 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 from 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 extend at their base from a height on the body different from that of the protrusions 22a and 22b. The difference in height d on the body 20 of the protrusions 22c and 22a or 22b can be between 0 and 1.5mm.

In the case where the application elements have several protuberances 22a, 22b or 22c respectively extending on the same side of the body, the latter may be identical and be connected to the body at heights h different from the latter. . 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 1mm. 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 rectilinear part C _a of the elongation axis C of the base of the application element 20 _p at its distal end 20 _d , can be between 0.2 mm and 5 mm, preferably 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 cor17, the angle γ being for example substantially equal to 65 °.

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 FIG. 10, all the protrusions 22 of the application elements 18a are such that, for all the cross sections T of the protuberance 22, progressing from the base 23 of the protuberance 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 can 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 3 mm, 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 have a shape different from that of the protrusions 22a and 22b, in particular because of their orientations relative to the different core.

Other embodiments of the invention are described below in connection with Figures 11 to 31. They differ from the first embodiment by the shape of the application elements 18 and their arrangement on the core 10.

Only the differences of these embodiments with respect to the first embodiment are described.

In the example illustrated in Figures 11 to 16, each applicator element 18a comprises a body 20 and two protrusions 22a and 22b extending laterally from the body 20. The body 20 has an enlarged distal end 20b.

The enlarged distal end 20b of each body 20, as illustrated in FIG. 14a, can be rounded, in particular in the form of a disc.

[0164] Preferably, the distal end is flattened along a plane of symmetry M _o of the application element as illustrated in FIG. 14b, so that it does not protrude laterally from the base. In this example, the application element is delimited in profile view by two parallel planes Mi; M ₂ . These are spaced a distance A less than or equal to the largest dimension of the base of the applicator element. However, it could be otherwise and the distal end 20b may not be flattened.

The application elements 18a extend along extension axes Y all inclined relative to the radial axis R at their base, in particular by the same angle β. The extension axes Y may extend in a transverse plane of the longitudinal axis X or, preferably, be inclined relative to such a transverse plane.

The application elements 18b are all inclined relative to the radial axis R at their base, in particular by the same angle a. The applicator elements 18b can extend in a plane transverse to the longitudinal axis X or, preferably, be inclined relative to such a transverse plane.

The length d of the widened distal part 22, measured along the axis of elongation Y, is for example greater than or equal to 0.1 mm, better still 0.5 mm.

The ratio d / l, where l denotes the total height of the body 20, is for example between 15% and 50%.

The application elements 18a each have two protrusions 22a and 22b each extending along an extension axis P contained in the same plane, in particular by being oriented circumferentially around the core. The protrusions 22a and 22b extend on either side of the body 20.

The protrusions 22a and 22b, as illustrated, are all of substantially identical shapes. They have a constant cross section and a rounded distal end. As a variant, the cross section can vary, in particular decrease towards their distal end.

The protrusions 22a and 22b extend from the body from the same height h, being symmetrical to each other with respect to the extension axis Y.

The extension axes P of the protrusions 22a and 22b each form an external angle γ with the extension axis Y of the body between 45 ° and 135 °. In the example illustrated, the protrusions extend in the direction of the free end of the corresponding application element 18a, the angle γ being substantially equal to 120 °.

The application elements 18a have protuberances 22a; 22b extending in the distal half of the application element, so as to constitute product reserves at a distance from the soul.

Preferably, each application element 18a is symmetrical with respect to a median plane M, but it could be otherwise.

In the example considered, as can be seen in particular in FIGS. 15 to 17, the free ends of the application elements 18a define an envelope surface SI of the application member 8, of rectilinear longitudinal axis and coincident with the longitudinal axis X of the core 10. The envelope SI is symmetrical in revolution around said axis X, having in particular the shape of a peanut, that is to say of elongated cylindrical shape and comprising a throttling at its center, as can be seen in particular in Figure 6. The envelope surface SI has, in the example illustrated, a cross section which varies over the entire length of the applicator member 8, admitting in particular three local minima , at points substantially corresponding to the distal end of the applicator member, in the middle of the length H of the applicator member 8 and to the proximal end of the applicator member.

The application elements 18b are substantially identical to the additional application elements described in relation to the first embodiment.

They differ from those described above in that the angle a is between 0 ° and 10 °, for example substantially equal to 5 °.

In the embodiment of FIGS. 19 to 23, the applicator member 8 comprises only one kind of applicator elements 18 extending from the core 10.

The application elements 18 each comprise a body 20 and two protuberances 22 projecting from the surface of the body 20. The latter has a straight portion 20a extending from its base and a distal end 20b bent, preferably in the form of a hook.

Preferably, the body 20 extends along an elongation axis C having a straight portion at the level of the straight portion 20a and a curved portion at the distal end 20b bent of the body 20. The axis elongation C may have a curvature having a radius of curvature r of between 0.2 and 2 mm, preferably substantially equal to 0.3 mm.

Preferably, the distal end 20b of the body extends in an arc of a circle with an angular extent λ between 90 ° and 180 °, better still between 135 ° and 180 °, for example substantially equal to 150 ° .

[0182] Preferably, the rectilinear portion 20a has a decreasing cross section from the base towards the distal end 20b.

[0183] Preferably, the elongation axis C extends in a plane transverse to the longitudinal axis of the core.

The protrusions 22 are also bent. They extend along an axis of extension P contained in the same plane as the body 20, in particular in a plane transverse to the longitudinal axis X of the core 10. The protrusions 22 preferably extend on the same side of the body 20 as the distal end 20b. They extend to different heights of the body 20 from the rectilinear portion 20a of the body.

Preferably, the extension axes P of the protrusions are curved and have a radius of curvature r _p substantially identical to that r of the distal end 20b. Preferably, the protrusions extend along an arc of a circle of angular extent λ _ρ less than the distal end 20b.

Preferably, the distal end 20a and the protuberances 22 extend laterally from the body 20 up to the same distance d from the straight part of the elongation axis C.

As illustrated in FIG. 23, the application elements 18 preferably extend radially, ie the rectilinear part of their axis of elongation C is substantially coincident with a radius Y starting from the axis X at their based.

As can be seen in Figures 19 and 20, the application elements 18 are arranged in two helical rows nested around the longitudinal axis X of the core. The distal ends 20b of the application elements 18c of the first row are preferably oriented on one side of the straight portion 20a of the body opposite to that of the application elements 18d of the second row. This accentuates the abundant effect of the application elements on the core in front view, as illustrated in FIG. 20.

In the example considered, as visible in particular in FIG. 22, the free ends of the application elements 18 define an envelope surface S of the application member 8, of rectilinear longitudinal axis and coinciding with the longitudinal axis X of the core 10. The envelope S is symmetrical in revolution about said axis X, in particular having a cross section passing through a maximum at its center, that is to say having a portion of increasing section of l the proximal end towards the distal end, then a portion of decreasing section up to the distal end. The envelope surface SI has, in the example illustrated, a cross section which varies over the entire length of the applicator member 8.

In the embodiment illustrated in FIGS. 24 to 27, the applicator member 8 has applicator elements 18a in the form of a loop and applicator elements 18b in the form of pins.

The application elements 18a extend from the core by two straight feet 20a connected together at their distal ends by a rounded portion 20b. The rounded portion 20b has reliefs 40 on its outwardly facing surface in the form of several bumps separated by a hollow. Such reliefs make it possible to constitute product reserves.

The application elements 18a extend radially in a longitudinal plane of the core 10.

The application elements 18b extend radially.

In this embodiment, the application elements 18a and 18b do not alternate within the helical rows. The applicator member 8 comprises two nested helical rows, one of the rows being a row of applicator elements 18a in the form of loops as described above, and the other row being a row of elements 18b application in the form of spikes.

In the embodiment illustrated in FIGS. 28 to 31, the applicator member 8 includes applicator elements 18a in the form of loops and applicator elements 18b in the form of pins.

The application elements 18a extend from the core by two feet 20a connected together at their distal ends by a rounded portion 20b, as illustrated in FIG. 31. The feet 20a are wavy but they could alternatively be straight.

The application elements 18a extend in a transverse plane of the core 10.

The applicator elements 18b in the form of pins extend radially. The application elements 18a can extend along an axis of elongation C which forms a non-zero angle β with a radius at the base of the application element 18a, as illustrated in FIG. 31.

In this embodiment, the application elements 18a and 18b do not alternate in the helical rows. The applicator member 8 has four nested helical rows. Two of the rows are rows of application elements 18a in the form of loops as described above, extending over the respective strands of material 12 and 14 from the core 10 between the grooves 16 and 17, and the other two rows are rows of application elements 18b in the form of pins extending in the grooves 16 and 17 respectively, as illustrated in FIGS. 28 and 30.

The invention is not limited to the embodiments described above. In particular, the forms of application elements of the various embodiments can be combined with the different arrangements of application elements on the core described above.

The forms of application elements can be other than those described above.

For example, the applicator element may include one or more protuberances in the form of a beak oriented towards the outside or towards the core and connecting to the core by planar, concave or convex surfaces , in the form of a triangle connecting to the body by one of its edges, in the form of a boss of the body, in the form of a hook oriented towards the base or outside, in the form of 'a loop or in the form of a mushroom.

The application element may also have an enlarged distal end in the form of a half-disc. The enlarged distal end can be solid or hollow.

The application elements may be in the form of teeth with or without one or more protruding reliefs, pins having one or more elbows, V-shaped, X or having a V or X at the end , or in the form of an open loop. Application elements may not have an axis of symmetry.

In the examples illustrated, the application elements 18a of the application members are all in one or two forms. The app body could have more than two different forms of app elements.

[0206] 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 32a-f and 33, 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. 32a 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. 32a, 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. 32b. 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. 32c. 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. 32d. The process explained above can then be repeated to generate the three-dimensional applicator layer by layer as illustrated in Figures 32d-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 device for manufacturing by different additive synthesis, in particular by light irradiation of a photo-crosslinkable material, as illustrated in FIGS. 34 and 35 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. 34, 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. 35, 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 tank 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.

[0216] 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 embodiments described above.

The device can include a product reservoir and the applicator can be mounted by its proximal end 13 on the reservoir. In this case, the applicator has a hollow core and at least one perforation allowing the cosmetic product to be supplied to the applicator.
