Description

DESCRIPTION DESCRIPTION
TITRE : Applicateur pour produit cosmétique, notamment du mascara, ensemble applicateur associé et procédé de fabrication d’un tel applicateur TITLE: Applicator for cosmetic product, in particular mascara, associated applicator assembly and method of manufacturing such an applicator
Domaine technique de l'invention Technical field of the invention
L’invention concerne un applicateur pour produit cosmétique, notamment du mascara, et un ensemble applicateur associé. L’invention concerne en outre un procédé pour la fabrication d’un tel applicateur. The invention relates to an applicator for a cosmetic product, in particular mascara, and an associated applicator assembly. The invention further relates to a process for the manufacture of such an applicator.
Arrière-plan technique Technical background
Les applicateurs mascara peuvent être obtenus à partir d’éléments fibreux maintenus entre les parties longitudinales d’une broche métallique torsadée ; ils sont alors communément appelés « brosses torsadées ». Les extrémités des éléments fibreux forment habituellement des enveloppes selon une direction d’extension longitudinale de la brosse. Les brosses torsadées présentent, par leur mode de fabrication, une enveloppe de forme cylindrique qui offre peu de possibilités en termes d’effets de maquillage. De nombreuses solutions ont déjà été proposées pour conférer des formes variées à des brosses torsadées. Mascara applicators can be obtained from fibrous elements held between the longitudinal parts of a twisted metal pin; they are then commonly called "twisted brushes". The ends of the fibrous elements usually form envelopes in a direction of longitudinal extension of the brush. The twisted brushes have, by their mode of manufacture, a cylindrical envelope which offers few possibilities in terms of makeup effects. Numerous solutions have already been proposed for imparting various shapes to twisted brushes.
Les applicateurs mascara peuvent aussi être obtenus par moulage par injection de matière plastique, ils sont alors communément appelés « brosses plastiques ». Ainsi les brosses plastiques peuvent présenter des formes originales afin de proposer des effets de maquillage particuliers. Mascara applicators can also be obtained by injection molding of plastic material, they are then commonly called “plastic brushes”. Thus the plastic brushes can have original shapes in order to offer particular makeup effects.
Il existe cependant toujours un besoin de perfectionnement des applicateurs mascara, notamment pour obtenir des applicateurs assurant une charge suffisante en produit cosmétique et une bonne restitution de celui-ci, tout en conservant une souplesse d’application du produit cosmétique. However, there is still a need to improve mascara applicators, in particular to obtain applicators ensuring a sufficient load of cosmetic product and good restitution of the latter, while maintaining flexibility of application of the cosmetic product.
Résumé de l'invention L’invention concerne un applicateur pour produit cosmétique, comprenant : Summary of the invention The invention relates to an applicator for a cosmetic product, comprising:

Ladite âme et/ou le au moins un élément mobile comprennent une pluralité de protubérances faisant saillie. - at least one mobile element extending over all or part of a length of the core from a first end attached to the core to a second free end moving relative to the core. Said core and / or the at least one movable element comprise a plurality of protruding protuberances.
Contrairement aux applicateurs comprenant des éléments dont les deux extrémités sont fixés à l’âme pour lesquels une pression sur ces éléments entraîne une déformation élastique, par exemple en M avec un pincement central et une répartition non-uniforme du produit cosmétique le long de l’âme, dans un tel applicateur, une pression sur l’élément mobile entraîne un déplacement de celui-ci par rapport à l’âme ce qui conduit à une répartition du produit cosmétique sur toute la longueur de l’âme. Unlike applicators comprising elements whose two ends are fixed to the core for which pressure on these elements results in an elastic deformation, for example in M with a central pinch and a non-uniform distribution of the cosmetic product along the core, in such an applicator, pressure on the movable element causes the latter to move relative to the core, which results in distribution of the cosmetic product over the entire length of the core.
Cette amélioration de la répartition du produit cosmétique permet un meilleur chargement en produit cosmétique et les cils peuvent être enveloppés d’un maximum de produit cosmétique ce qui augmente l’effet de volume, notamment en fonction de la pression exercée. Il est ainsi possible de diminuer la longueur des protubérances pour améliorer le peignage des cils. This improvement in the distribution of the cosmetic product allows a better loading of cosmetic product and the eyelashes can be wrapped in a maximum of cosmetic product which increases the volume effect, in particular as a function of the pressure exerted. It is thus possible to reduce the length of the protuberances in order to improve the combing of the eyelashes.
Par ailleurs, l’utilisation d’un élément s’étendant sur tout ou partie d’une longueur de l’âme permet d’utiliser une âme présentant une section transversale de dimension inférieure à celle d’un applicateur classique. Cela permet d’avoir un applicateur plus souple. De même, le déplacement par rapport à l’âme d’une des extrémités de l’élément mobile permet aussi d’apporter de la souplesse à l’applicateur. Furthermore, the use of an element extending over all or part of a length of the core makes it possible to use a core having a cross section of smaller dimension than that of a conventional applicator. This allows for a more flexible applicator. Likewise, the displacement of one end of the movable element relative to the core also allows flexibility in the applicator.

Description détaillée de l'invention Detailed description of the invention
Comme illustré sur la figure 1 , l’invention concerne un applicateur 1 pour produit cosmétique, notamment pour mascara, comprenant une âme 2 s’étendant le long d’une direction d’extension longitudinale, dite direction principale et repérée X sur la figure 1. L’âme 2 présente une extrémité proximale 2b apte à être fixée à une tige 3 d’applicateur 1 par un manchon 4 prolongeant l’âme 2, et une extrémité libre, appelée aussi extrémité distale 2a, opposée à l’extrémité proximale 2b le long de la direction principale X. Selon l’invention, l’applicateur 1 comprend en outre au moins un élément 5, 5A, 5B mobile s’étendant sur tout ou partie d’une longueur de l’âme 2 d’une première extrémité 5a, 5aA, 5aB fixée à l’âme 2 vers une deuxième extrémité 5b, 5bA, 5bB libre en déplacement par rapport à l’âme 2. La deuxième extrémité 5b, 5bA, 5bB est opposée à la première extrémité 5a, 5aA, 5aB. L’applicateur 1 comprend en outre une pluralité de protubérances 7.1 venues de matière avec l’âme 2 et une pluralité de protubérances 7.2, 7.2a, 7.2B venues de matière avec l’élément 5, 5A, 5B mobile. As illustrated in FIG. 1, the invention relates to an applicator 1 for a cosmetic product, in particular for a mascara, comprising a core 2 extending along a direction of longitudinal extension, called the main direction and marked X in FIG. 1. The core 2 has a proximal end 2b capable of being fixed to a rod 3 of applicator 1 by a sleeve 4 extending the core 2, and a free end, also called distal end 2a, opposite the proximal end 2b along the main direction X. According to the invention, the applicator 1 further comprises at least one mobile element 5, 5A, 5B extending over all or part of a length of the core 2 from a first end 5a, 5aA, 5aB fixed to the core 2 towards a second end 5b, 5bA, 5bB free in displacement relative to the core 2. The second end 5b, 5bA, 5bB is opposite the first end 5a, 5aA, 5aB. The applicator 1 further comprises a plurality of protrusions 7.1 integral with the core 2 and a plurality of protuberances 7.2, 7.2a, 7.2B integral with the mobile element 5, 5A, 5B.
De façon avantageuse, l’âme 2, l’élément 5, 5A, 5B mobile et les protubérances 7.1 , 7.2, 7.2a, 7.2B sont ainsi réalisés en une seule pièce. Advantageously, the core 2, the mobile element 5, 5A, 5B and the protuberances 7.1, 7.2, 7.2a, 7.2B are thus made in one piece.
Le manchon 4 est dépourvu de protubérances. The sleeve 4 is devoid of protuberances.
De façon avantageuse, ledit au moins un élément 5, 5A, 5B mobile se déplace selon un débattement angulaire par rapport à l’âme 2. De préférence, le débattement angulaire est compris entre -30° et +30°, voire entre -10° et +10°, voire de préférence entre -2,5° et +2,5°. Advantageously, said at least one mobile element 5, 5A, 5B moves according to an angular movement with respect to the web 2. Preferably, the angular movement is between -30 ° and + 30 °, or even between -10 ° and + 10 °, or even preferably between -2.5 ° and + 2.5 °.
Dans le mode de réalisation représenté aux figures 1 à 6, l’élément 5 mobile comprend trois branches 9 s’étendant selon la direction d’extension X de l’âme 2 de la première extrémité 5a fixée au niveau de l’extrémité distale 2a de l’âme 2 vers la deuxième extrémité 5b reliée à un anneau 1 1 formant l’extrémité libre en déplacement par rapport à l’âme 2 de l’élément 5 mobile. L’anneau 1 1 entoure l’âme de manière à ce que l’âme passe à travers celui-ci. De façon avantageuse, l’anneau 1 1 est circulaire. L’anneau présente une surface interne 11 i dirigée vers l’âme 2 et une surface externe 1 1 e dirigée vers l’extérieure Les branches 9 s’étendent sur toute la longueur de l’âme 2 de l’extrémité distale 2a de celle-ci à laquelle elles sont fixées vers son extrémité proximale 2b où elles sont libres en déplacement par rapport à l’âme 2. In the embodiment shown in Figures 1 to 6, the mobile element 5 comprises three branches 9 extending in the direction of extension X of the core 2 of the first end 5a fixed at the level of the distal end 2a of the core 2 towards the second end 5b connected to a ring 1 1 forming the free end in displacement with respect to the core 2 of the movable element 5. The ring 1 1 surrounds the soul so that the soul passes through it. Advantageously, the ring 1 1 is circular. The ring has an internal surface 11 i directed towards the core 2 and an external surface 1 1 e directed towards the outside The branches 9 extend over the entire length of the core 2 from the distal end 2a of that - here to which they are fixed towards its proximal end 2b where they are free to move relative to the core 2.
Les branches 9 sont régulièrement angulairement réparties autour de l’âme 2. The branches 9 are regularly angularly distributed around the core 2.
De préférence, les branches sont régulièrement angulairement réparties autour de l’anneau 1 1 . Preferably, the branches are regularly angularly distributed around the ring 1 1.
Dans le mode de réalisation illustré aux figures 1 à 6, les trois branches sont ainsi espacées régulièrement autour de la direction principale X avec un espace angulaire sensiblement égal à 120° d’angle. In the embodiment illustrated in Figures 1 to 6, the three branches are thus regularly spaced around the main direction X with an angular space substantially equal to 120 ° angle.
De façon avantageuse, l’élément 5 mobile peut ainsi se déplacer selon un débattement angulaire par rapport à l’âme 2 selon des directions transversales à la direction principale. Advantageously, the mobile element 5 can thus move according to an angular movement relative to the web 2 in directions transverse to the main direction.
De façon avantageuse, l’anneau 1 1 permet de lier entre-elles les branches 9 de manière à former un ensemble solidaire (l’élément 5 mobile) dont un mouvement d’une zone (une des branches 9, par exemple) entraîne le mouvement d’une autre zone (une autre des branches 9, par exemple). Autrement dit, l’anneau 1 1 permet de rendre le mouvement d’une des branches 9 dépendante du mouvement d’une autre ou des autres branches 9. Advantageously, the ring 1 1 allows the branches 9 to be linked together so as to form an integral assembly (the movable element 5) of which a movement of an area (one of the branches 9, for example) causes the movement of another zone (another of the branches 9, for example). In other words, the ring 1 1 makes it possible to make the movement of one of the branches 9 dependent on the movement of another or other branches 9.
Les branches 9 restent solidaires l’une par rapport à l’autre grâce à l’anneau 1 1 . The branches 9 remain integral with each other thanks to the ring 1 1.
Le débattement angulaire par rapport à l’âme 2 est induit, par exemple, lors de l’application du produit cosmétique, par la résistance entre le produit cosmétique et la surface à maquiller ou encore lors de la sortie et/ou l’entrée d’un récipient 13 contenant le produit cosmétique. The angular movement with respect to the core 2 is induced, for example, during the application of the cosmetic product, by the resistance between the cosmetic product and the surface to be made up or even during the exit and / or the entry of 'a container 13 containing the cosmetic product.
De façon avantageuse, l’anneau est dimensionné de manière optimale pour permettre le déplacement angulaire de l’élément 5 mobile et pour fonctionner avec un goulot ou un orifice d’ouverture 14 du récipient 13. Advantageously, the ring is optimally dimensioned to allow the angular displacement of the element 5 mobile and to operate with a neck or an opening 14 of the container 13.
De façon avantageuse, les branches 9 sont raccordées à l’âme 2 par une seule de leur extrémité. Advantageously, the branches 9 are connected to the core 2 by only one of their end.
Dans le mode de réalisation illustré aux figures 1 à 6, l’élément 5 mobile est ainsi libre de tout contact avec l’âme 2 à l’exception d’une extrémité, ici l’extrémité distale 5b. In the embodiment illustrated in Figures 1 to 6, the movable element 5 is thus free from any contact with the core 2 except for one end, here the distal end 5b.
Les trois branches 9 sont séparées par trois ouvertures 15 longitudinales de forme allongée selon la direction d’extension X de l’âme 2 et forment une paroi autour de l’âme 2. The three branches 9 are separated by three longitudinal openings 15 of elongated shape in the direction of extension X of the core 2 and form a wall around the core 2.
De façon avantageuse, les ouvertures 15 sont régulièrement angulairement réparties autour de l’âme 2. Advantageously, the openings 15 are regularly angularly distributed around the core 2.
Dans le mode de réalisation illustré aux figures 1 à 6, les trois ouvertures 15 sont ainsi espacées régulièrement autour de la direction principale X avec un espace angulaire sensiblement égal à 120° d’angle. In the embodiment illustrated in Figures 1 to 6, the three openings 15 are thus regularly spaced around the main direction X with an angular space substantially equal to 120 ° angle.
L’élément 5 mobile a ainsi une forme d’ogive allongée selon une direction sensiblement coaxiale à la direction principale X et enveloppe l’âme 2 sur toute sa longueur. The mobile element 5 thus has the shape of an elongated bullet in a direction substantially coaxial with the main direction X and envelops the core 2 over its entire length.
Les protubérances 7.1 de l’âme 2 font saillie à travers les ouvertures 15 et chacune des branches 9 comprend aussi des protubérances 7.2 de manière à ce que des rangées longitudinales de protubérances 7.2 de l’élément 5 mobile alternent avec des rangées longitudinales de protubérances 7.1 de l’âme 2. L’applicateur 1 comprend ainsi des protubérances 7.2 mobiles agencées sur les banches 9 de l’élément 5 mobile et des protubérances 7.1 fixes agencées sur l’âme 2. The protrusions 7.1 of the core 2 protrude through the openings 15 and each of the branches 9 also comprises protrusions 7.2 so that longitudinal rows of protuberances 7.2 of the mobile element 5 alternate with longitudinal rows of protuberances 7.1 of the core 2. The applicator 1 thus comprises movable protuberances 7.2 arranged on the formwork 9 of the movable element 5 and fixed protuberances 7.1 arranged on the core 2.
La présence de l’élément 5 mobile permet d’avoir un applicateur 1 présentant une enveloppe E externe volumineuse, mais dont l’âme 2 centrale présente un diamètre restreint ce qui en améliore la flexibilité et ainsi la souplesse d’utilisation. The presence of the mobile element 5 makes it possible to have an applicator 1 having a bulky outer envelope E, but the central core 2 of which has a small diameter, which improves its flexibility and thus the flexibility of use.
L’enveloppe E est formée par des extrémités libres 72 des protubérances 7.1 , 7.2 agencées sur l’âme et l’élément 5 mobile. L’enveloppe E présente ici une section transversale de forme générale circulaire. The envelope E is formed by free ends 72 of the protuberances 7.1, 7.2 arranged on the core and the mobile element 5. The envelope E here has a cross section of generally circular shape.
Le fait qu’une extrémité 5a, 5b de l’élément 5 mobile soit libre en déplacement par rapport à l’âme 2 permet un mouvement homogène sur toute la longueur de l’élément 5 mobile lorsqu’une pression est exercée ce qui entraîne une meilleure répartition et/ou une meilleure expulsion du produit cosmétique le long de l’âme 2. Les cils peuvent être enveloppés d’un maximum de produit cosmétique ce qui augmente l’effet de volume. The fact that one end 5a, 5b of the movable element 5 is free to move relative to the core 2 allows homogeneous movement over the entire length of the movable element 5 when pressure is exerted which results in a better distribution and / or better expulsion of the cosmetic product along the core 2. The eyelashes can be wrapped in a maximum of cosmetic product, which increases the volume effect.
L’élément 5 mobile permettant une meilleure homogénéité du produit cosmétique le long de l’âme 2, il est alors possible, de façon avantageuse, de diminuer la longueur des protubérances 7.1 , 7.2 de manière à favoriser le peignage. The mobile element 5 allowing better homogeneity of the cosmetic product along the core 2, it is then possible, advantageously, to reduce the length of the protuberances 7.1, 7.2 so as to promote combing.
Le déplacement de l’élément 5 mobile permet ainsi, avantageusement de faire varier la longueur de la portion des protubérances 7.1 sortant de l’ouverture 15. Ainsi, avec un même applicateur, en fonction de la position de l’élément 5 mobile par rapport à l’âme 2, il est possible d’avoir l’impression d’utiliser un applicateur avec des protubérances longues (avantageuses pour la charge en produit cosmétique) ou des protubérances courtes (avantageuses pour le peignage des cils). The movement of the mobile element 5 thus advantageously makes it possible to vary the length of the portion of the protuberances 7.1 emerging from the opening 15. Thus, with the same applicator, as a function of the position of the mobile element 5 with respect to at core 2, it is possible to have the impression of using an applicator with long protuberances (advantageous for the cosmetic product load) or short protuberances (advantageous for combing the eyelashes).
Mis à part une extrémité de l’élément 5 mobile, le reste est situé radialement à une distance d de ladite âme 2 de manière à former un volume réservoir V. Apart from one end of the mobile element 5, the rest is located radially at a distance d from said core 2 so as to form a reservoir volume V.
Autrement dit, il est possible de stocker du produit cosmétique dans l’espace compris radialement entre l’élément 5 mobile et l’âme 2, c'est-à-dire entre une surface interne 5i de l’élément 5 mobile et une surface externe 2e de l’âme 2. In other words, it is possible to store cosmetic product in the space comprised radially between the mobile element 5 and the core 2, that is to say between an internal surface 5i of the mobile element 5 and a surface external 2nd of web 2.
La distance d peut ainsi varier, en particulier diminuer, lorsqu’une pression est appliquée sur l’élément 5 mobile, tel qu’illustré à la figure 3. Ce mouvement radial provoque l’expulsion du produit cosmétique stocké dans le volume réservoir V. De façon avantageuse, les ouvertures 15 peuvent aussi servir de réservoir pour le produit cosmétique. The distance d can thus vary, in particular decrease, when pressure is applied to the mobile element 5, as illustrated in FIG. 3. This radial movement causes the expulsion of the cosmetic product stored in the reservoir volume V. Advantageously, the openings 15 can also serve as a reservoir for the cosmetic product.
Là encore, le mouvement de l’élément 5 mobile permet de rendre plus ou moins disponible le produit cosmétique stocké. Here again, the movement of the mobile element 5 makes it possible to make the stored cosmetic product more or less available.
Lorsque l’élément 5 mobile est proche de l’âme 2 le produit cosmétique est facilement disponible et restituable aux cils. Inversement, lorsque l’élément 5 mobile est éloigné de l’âme 2, le produit cosmétique est moins disponible et les protubérances 7.1 de l’âme 2 servent alors, par exemple, au peignage des cils. When the mobile element 5 is close to the core 2, the cosmetic product is easily available and can be returned to the eyelashes. Conversely, when the mobile element 5 is moved away from the core 2, the cosmetic product is less available and the protuberances 7.1 of the core 2 are then used, for example, for combing the eyelashes.
Dans le mode de réalisation représenté aux figures 1 à 6, les protubérances 7.1 , 7.2 font saillie à partir de l’âme 2 et de l’élément 5 mobile, notamment à partir des surfaces externes des branches 9, suivant une direction sensiblement normale par rapport à la direction principale X, dite direction radiale. In the embodiment shown in Figures 1 to 6, the protuberances 7.1, 7.2 protrude from the core 2 and the movable element 5, in particular from the outer surfaces of the branches 9, in a direction substantially normal by relative to the main direction X, called the radial direction.
On entend par « les protubérances 7.1 , 7.2 font saillie à partir de l’âme 2 et de l’élément 5 mobile suivant une direction sensiblement normale par rapport à la direction principale X », des protubérances 7.1 , 7.2 qui font saillie dans un plan comprenant la direction principale X et une direction radiale de la direction X. Autrement dit, les protubérances 7.1 , 7.2 pourront être inclinées, dans ce plan, vers l’extrémité proximale et/ou distale, ceci sans sortir du cadre de l’invention. The expression “the protuberances 7.1, 7.2 protrude from the web 2 and the movable element 5 in a direction substantially normal to the main direction X” is understood to mean protrusions 7.1, 7.2 which protrude in a plane comprising the main direction X and a radial direction of the direction X. In other words, the protuberances 7.1, 7.2 may be inclined, in this plane, towards the proximal and / or distal end, this without departing from the scope of the invention.
Dans d’autres modes de réalisation non représentés, les protubérances 7.1 , 7.2 peuvent présenter une inclinaison. Elles peuvent, par exemple, faire saillie à partir de l’âme 2 en formant un angle avec la direction principale X différent de 90 °. Autrement dit, les protubérances 7.1 , 7.2 peuvent être inclinées vers l’extrémité distale 2a de l’âme 2 ou inclinées vers l’extrémité proximale 2b de l’âme 2. Toute autre inclinaison peut être aussi envisageable. Les protubérances 7.1 , 7.2 peuvent aussi présenter une inclinaison différente l’une par rapport à l’autre. Les protubérances 7.1 , 7.2 s’étendent d’une extrémité 71 solidaire de l’âme 2 ou de l’élément 5 mobile vers l’extrémité libre 72 selon une direction d’élongation de manière à définir une longueur.In other embodiments not shown, the protuberances 7.1, 7.2 may have an inclination. They can, for example, project from the core 2 by forming an angle with the main direction X other than 90 °. In other words, the protuberances 7.1, 7.2 can be inclined towards the distal end 2a of the core 2 or inclined towards the proximal end 2b of the core 2. Any other inclination can also be envisaged. The protuberances 7.1, 7.2 can also have a different inclination with respect to one another. The protrusions 7.1, 7.2 extend from one end 71 integral with the core 2 or the movable element 5 towards the free end 72 in an elongation direction so as to define a length.
On entend par « longueur » des protubérances 7.1 , 7.2, la longueur mesurée entre la périphérie radiale de l’âme 2 ou de l’élément 5 mobile et l’extrémité distale libre 72 de la protubérance 7.1 , 7.2. Autrement dit, on entend par « longueur » des protubérances 7.1 , 7.2 leur extension radiale mesurée à partir de la base de la protubérance 7.1 , 7.2, en projection sur un plan orthogonal à la direction principale X. The term "length" of the protuberances 7.1, 7.2 is understood to mean the length measured between the radial periphery of the core 2 or of the mobile element 5 and the free distal end 72 of the protuberance 7.1, 7.2. In other words, by "length" of the protuberances 7.1, 7.2 is meant their radial extension measured from the base of the protuberance 7.1, 7.2, in projection on a plane orthogonal to the main direction X.
Dans le mode de réalisation représenté, les protubérances 7.1 , faisant saillie de l’âme 2 et les protubérances 7.2 faisant saillie des branches 9 de l’élément 5 mobile présentent des longueurs différentes de manière que la distance entre le centre de l’âme 2 et l’extrémité libre 72 des protubérances 7.1 , 7.2 comprise dans un même plan transversal à l’axe principal X soit sensiblement identique. In the embodiment shown, the protuberances 7.1, projecting from the core 2 and the protuberances 7.2 projecting from the branches 9 of the mobile element 5 have different lengths so that the distance between the center of the core 2 and the free end 72 of the protuberances 7.1, 7.2 included in the same plane transverse to the main axis X is substantially identical.
En revanche, la distance entre le centre de l’âme 2 et l’extrémité libre 72 des protubérances 7.1 , 7.2 diminue en direction des extrémités proximale 1 b et distale 1 a de l’applicateur 1 de manière à former une enveloppe E en forme d’ogive. L’enveloppe E présente un diamètre DE maximal au niveau du centre de la longueur de l’âme 2. L’enveloppe E en forme d’ogive facilite notamment l’insertion de l’applicateur 1 à travers le goulot ou l’orifice d’ouverture 14 du récipient 13 contenant le produit cosmétique et l’application du produit cosmétique au niveau du coin interne de l’œil. On the other hand, the distance between the center of the core 2 and the free end 72 of the protuberances 7.1, 7.2 decreases towards the proximal 1b and distal 1a ends of the applicator 1 so as to form an envelope E in the form of warhead. The envelope E has a maximum diameter DE at the level of the center of the length of the core 2. The envelope E in the form of an ogive facilitates in particular the insertion of the applicator 1 through the neck or the orifice d. opening 14 of the container 13 containing the cosmetic product and the application of the cosmetic product at the level of the inner corner of the eye.
Dans d’autres modes de réalisation non représentés, la distance entre le centre de l’âme 2 et l’extrémité libre 72 des protubérances 7.1 , 7.2 peut varier de manière, par exemple, à former une enveloppe de forme sensiblement cylindrique ou de forme originale présentant des zones convexes et/ou concaves. Dans le mode de réalisation illustré aux figures 1 à 6, les protubérances 7.1 , 7.2 présentent une section transversale quadrilatère, notamment carré, de dimension et de forme identique sur toute leur longueur. In other embodiments not shown, the distance between the center of the core 2 and the free end 72 of the protuberances 7.1, 7.2 can vary so as, for example, to form an envelope of substantially cylindrical shape or shape. original with convex and / or concave areas. In the embodiment illustrated in Figures 1 to 6, the protuberances 7.1, 7.2 have a quadrilateral cross section, in particular square, of identical size and shape over their entire length.
Il est aussi envisageable dans un mode de réalisation non représenté que les protubérances 7.1 , 7.2 présentent une section transversale dont la dimension est supérieure au voisinage de l’extrémité 71 qu’au voisinage de l’extrémité libre 72 de la protubérance 7.1 , 7.2. Autrement dit, la section transversale de la protubérance 7.1 , 7.2 présente une dimension qui diminue de l’extrémité 71 vers l’extrémité libre 72. It is also conceivable in an embodiment not shown that the protuberances 7.1, 7.2 have a cross section whose dimension is greater in the vicinity of the end 71 than in the vicinity of the free end 72 of the protrusion 7.1, 7.2. In other words, the cross section of the protrusion 7.1, 7.2 has a dimension which decreases from the end 71 towards the free end 72.
L’âme 2 peut être pleine ou creuse sans sortir du cadre de l’invention. The core 2 can be solid or hollow without departing from the scope of the invention.
L’âme 2 présente ici une section transversale par rapport à la direction longitudinale X qui est circulaire. The core 2 here has a cross section with respect to the longitudinal direction X which is circular.
Dans des modes de réalisation non représentés, l’âme 2 peut aussi présenter une section transversale autre que circulaire, sans sortir du cadre de l’invention. La section transversale peut ainsi être polygonale, telle que triangulaire, ou en forme de quadrilatère, ou encore en forme de croix, d’étoile ou oblongue. L’âme 2 est de préférence de section transversale sensiblement constante de son extrémité proximale 2b à son extrémité distale 2a, tout du moins jusqu’à une partie évasée qui peut éventuellement être présente au niveau de l’extrémité distale 2a de l’âme 2. In embodiments not shown, the core 2 can also have a cross section other than circular, without departing from the scope of the invention. The cross section can thus be polygonal, such as triangular, or in the shape of a quadrilateral, or even in the shape of a cross, a star or an oblong. The core 2 is preferably of substantially constant cross section from its proximal end 2b to its distal end 2a, at least up to a flared part which may optionally be present at the level of the distal end 2a of the core 2. .
Dans le mode de réalisation représenté aux figures 1 à 6, les protubérances 7.1 , 7.2 faisant saillie de l’âme 2 et de l’élément 5 mobile sont agencées en trois rangées longitudinales R1 de protubérances 7.1 issues de l’âme 2 et en trois rangées R2 longitudinales de protubérances 7.2 issues de l’élément 5 mobile. Chacune des rangées R1 , R2 est formée de cinq lignes L1 , L2 de protubérances 7.1 , 7.2 parallèles à l’axe principal X arrangées de manière à ce que les protubérances 7.1 , 7.2 forment deux lignes qui s’entrecroisent au niveau d’une protubérance commune. In the embodiment shown in Figures 1 to 6, the protrusions 7.1, 7.2 projecting from the core 2 and the mobile element 5 are arranged in three longitudinal rows R1 of protuberances 7.1 from the core 2 and in three R2 longitudinal rows of protrusions 7.2 from the mobile element 5. Each of the rows R1, R2 is formed by five lines L1, L2 of protrusions 7.1, 7.2 parallel to the main axis X arranged in so that the protuberances 7.1, 7.2 form two lines which intersect at the level of a common protuberance.
Il est aussi envisageable, dans d’autres modes de réalisation non représentées que chacune des rangées soit une seule ligne de protubérances 7.1 , 7.2 parallèles à la direction principale X ou inclinées par rapport à la direction principale X, ou qu’elles s’enroulent de manière hélicoïdale autour de l’âme ou tout autre arrangement possibles. It is also conceivable, in other embodiments not shown, for each of the rows to be a single line of protuberances 7.1, 7.2 parallel to the main direction X or inclined with respect to the main direction X, or for them to wind up. helically around the core or any other possible arrangement.
L’enroulement hélicoïdal peut être tel que le décalage angulaire est compris entre 2 et 10°, de préférence de 5°, de manière à ce que vue de l’extrémité distale, les protubérances semblent former un disque plein. The helical winding can be such that the angular offset is between 2 and 10 °, preferably 5 °, so that when viewed from the distal end the protrusions appear to form a solid disc.
Comme autres arrangements possibles, les protubérances peuvent par exemple être agencées de manière à former un zigzag, ou encore une ondulation, c’est-à-dire être agencées de part et d’autre de l’axe principale X de manière à former des crêtes opposées, ou encore autrement dit de manière à former des angles alternativement saillants et rentrants. As other possible arrangements, the protuberances can for example be arranged so as to form a zigzag, or else an undulation, that is to say, be arranged on either side of the main axis X so as to form opposite ridges, or in other words so as to form alternately salient and re-entrant angles.
Dans d’autres modes de réalisation non représentés, les protubérances 7.1 , 7.2 faisant saillie de l’âme 2 et des deux branches 9 peuvent être disposées de façon aléatoire sans former de rangées longitudinales. In other embodiments not shown, the protrusions 7.1, 7.2 projecting from the core 2 and from the two branches 9 can be arranged randomly without forming longitudinal rows.
Dans un deuxième mode de réalisation illustré à la figure 7, l’applicateur 1 comprend deux éléments 5A, 5B mobiles. In a second embodiment illustrated in Figure 7, the applicator 1 comprises two mobile elements 5A, 5B.
Chacun des éléments 5A, 5B mobiles s’étend sur une partie de la longueur de l’âme 2 d’une première extrémité 5aA, 5aB fixée à l’âme 2 vers une deuxième extrémité 5bA, 5bB libre en déplacement par rapport à l’âme 2. Each of the movable elements 5A, 5B extends over part of the length of the core 2 from a first end 5aA, 5aB fixed to the core 2 towards a second end 5bA, 5bB free to move relative to the soul 2.
Le premier élément mobile, dit élément 5A mobile distal, est relié à l’âme 2 par une première extrémité 5aA fixée au niveau de l’extrémité distale 2a de l’âme 2. L’élément 5A mobile s’étend en direction de l’extrémité proximale 2b de l’âme 2 jusqu’à la deuxième extrémité 5bA libre en déplacement par rapport à l’âme 2 qui est située environ au centre de la longueur de l’âme 2. The first mobile element, called the distal mobile element 5A, is connected to the core 2 by a first end 5aA fixed at the level of the distal end 2a of the core 2. The mobile element 5A extends in the direction of the core. 'proximal end 2b of the core 2 up to the second end 5bA free in displacement with respect to the core 2 which is located approximately in the center of the length of the core 2.
Le deuxième élément mobile, dit élément 5B mobile proximal, est relié à l’âme 2 par une première extrémité 5aB fixée au niveau de l’extrémité proximale 2b de l’âme 2. L’élément 5B mobile s’étend en direction de l’extrémité distale 2a de l’âme 2 jusqu’à la deuxième extrémité 5bB libre en déplacement par rapport à l’âme 2 qui est située environ au centre de la longueur de l’âme 2. Autrement dit, chacun des éléments 5A, 5B mobiles se fait face à face de manière symétrique par rapport à un plan P orthogonal à la direction principale X. Les deux éléments 5A, 5B mobiles sont des images l’un de l’autre dans un miroir. Les deux éléments 5A, 5B mobiles forment ainsi une structure de forme ovoïde comme une cage autour de l’âme 2. The second mobile element, called the proximal mobile element 5B, is connected to the core 2 by a first end 5aB fixed at the level of the proximal end 2b of the core 2. The mobile element 5B extends in the direction of the core. 'distal end 2a of the core 2 to the second end 5bB free to move relative to the core 2 which is located approximately at the center of the length of the core 2. In other words, each of the elements 5A, 5B movable faces each other symmetrically with respect to a plane P orthogonal to the main direction X. The two movable elements 5A, 5B are images of one another in a mirror. The two mobile elements 5A, 5B thus form an ovoid-shaped structure like a cage around the core 2.
Chacun des éléments 5A, 5B mobiles est mobile par rapport à l’âme 2 indépendamment l’un de l’autre. Il est ainsi possible qu’un seul des deux éléments 5A, 5B mobiles présente un déplacement angulaire par rapport à l’âme 2, alors que l’autre des deux éléments 5B, 5A mobiles ne présente pas de déplacement. Cela offre une variété supplémentaire d’effets de maquillage. Each of the movable elements 5A, 5B is movable relative to the core 2 independently of one another. It is thus possible that only one of the two mobile elements 5A, 5B exhibits angular displacement with respect to the core 2, while the other of the two mobile elements 5B, 5A does not exhibit any displacement. This provides an additional variety of makeup effects.
Ce mode de réalisation diffère du premier de par la présence de deux éléments 5A, 5B mobiles qui s’étendent sur une partie seulement de l’âme 2. This embodiment differs from the first in the presence of two mobile elements 5A, 5B which extend over only part of the core 2.
Chacun des éléments 5A, 5B mobiles est sensiblement similaire à l’élément mobile 5 décrit précédemment dans le premier mode de réalisation. Each of the movable elements 5A, 5B is substantially similar to the movable element 5 described above in the first embodiment.
Par conséquent ce qui est décrit précédemment pour le premier mode de réalisation s’applique aussi pour ce deuxième mode de réalisation, en adaptant à la présence de deux éléments 5A, 5B mobiles. Consequently, what is described above for the first embodiment also applies for this second embodiment, adapting to the presence of two mobile elements 5A, 5B.
Les signes de références du premier mode de réalisation ont été repris. Ils sont suivis de la lettre « A » en ce qui concerne les signes de référence de l’élément 5A mobile distal et ils sont suivis de la lettre « B » en ce qui concerne les signes de référence de l’élément 5B mobile proximal. The reference signs of the first embodiment have been used. They are followed by the letter "A" with respect to the reference signs of the distal movable 5A element and they are followed of the letter "B" as regards the reference signs of the proximal movable element 5B.
Dans un autre mode de réalisation non représenté, les deux éléments mobiles peuvent être différents l’un de l’autre, notamment ils peuvent ne pas être symétriques. Par exemple, un des éléments mobiles peut s’étendre sur une longueur de l’âme supérieure à la longueur sur laquelle s’étend l’autre élément mobile. In another embodiment not shown, the two mobile elements may be different from each other, in particular they may not be symmetrical. For example, one of the movable elements may extend over a length of the core greater than the length over which the other movable element extends.
De façon avantageuse, l’applicateur 1 est une pièce unique monolithique obtenue sans assemblage. Autrement dit, l’applicateur 1 est non obtenu par assemblage. Advantageously, the applicator 1 is a single monolithic part obtained without assembly. In other words, the applicator 1 is not obtained by assembly.
Assemblage s’entend ici comme le fait de mettre ensemble, réunir au moins deux éléments isolés, mais n’exclue pas la possibilité de plusieurs étapes. Assembly is understood here as putting together, bringing together at least two isolated elements, but does not exclude the possibility of several steps.
Il est à noter aussi que l’applicateur 1 forme avantageusement une brosse. It should also be noted that the applicator 1 advantageously forms a brush.
De préférence, l’applicateur 1 décrit ci-dessus est obtenu par un procédé de fabrication additive. Preferably, the applicator 1 described above is obtained by an additive manufacturing process.
On entend par procédé de fabrication additive, un procédé de fabrication par ajout de matière, généralement assisté par ordinateur. Un tel procédé de fabrication est aussi appelé impression tridimensionnelle ou encore impression 3D. The term “additive manufacturing process” is understood to mean a manufacturing process by adding material, generally aided by computer. Such a manufacturing process is also called three-dimensional printing or even 3D printing.
De façon avantageuse, l’utilisation de l’impression tridimensionnelle peut permettre de réaliser en une seule étape un applicateur 1 en une seule pièce et en continuité de matière comprenant une âme 2 et au moins un élément 5, 5A, 5B mobile dont une extrémité est fixée à l’âme 2 et l’autre est libre en déplacement par rapport à l’âme 2, chacun présentant des protubérances 7.1 , 7.2, 7.2A, 7.2B. Un tel applicateur 1 pourrait s’avérer très complexe voire impossible à obtenir, notamment en une seule pièce, par un procédé classique de moulage par injection. Il est ainsi possible de réaliser, directement et par une unique opération de fabrication, l’applicateur 1. De plus, cette technique permet de s’affranchir de l’utilisation de moules complexes. Advantageously, the use of three-dimensional printing can make it possible to produce in a single step an applicator 1 in a single piece and in continuity of material comprising a core 2 and at least one mobile element 5, 5A, 5B, one end of which is fixed to the web 2 and the other is free to move relative to the web 2, each having protrusions 7.1, 7.2, 7.2A, 7.2B. Such an applicator 1 could turn out to be very complex or even impossible to obtain, in particular in a single piece, by a conventional injection molding process. It is thus possible to produce, directly and by a single manufacturing operation, the applicator 1. In addition, this This technique eliminates the need for complex molds.
Il peut aussi être envisagé en variante de réalisation que l’impression tridimensionnelle soit utilisée pour former l’âme 2 avec le manchon 4 et/ou la tige 3. It can also be envisaged as an alternative embodiment that the three-dimensional printing is used to form the core 2 with the sleeve 4 and / or the rod 3.

Le modèle numérique est un fichier informatique qui correspond à un modèle virtuel de l’applicateur 1. Pour l’obtenir, l’applicateur 1 est tout d’abord modélisé de manière à obtenir un modèle CAO qui est ensuite converti dans un format approprié tel qu’un fichier .STL. Le fichier est ensuite exploité sur une machine de fabrication additive. Lors de sa lecture, le modèle numérique est découpé en un certain nombre de couches en fonction de la précision souhaitée. De préférence, les couches correspondent à une section transversale de l’applicateur 1 , c'est-à-dire une section de l’applicateur 1 prise dans un plan perpendiculaire à la direction principale X. The digital model is a computer file which corresponds to a virtual model of the applicator 1. To obtain it, the applicator 1 is first of all modeled so as to obtain a CAD model which is then converted into an appropriate format such as than a .STL file. The file is then exploited on a machine of additive manufacturing. When it is read, the digital model is cut into a number of layers depending on the desired precision. Preferably, the layers correspond to a cross section of the applicator 1, that is to say a section of the applicator 1 taken in a plane perpendicular to the main direction X.
Les matériaux appropriés pour fabriquer l’applicateur 1 par une impression tridimensionnelle sont les polyamides, les résines photosensibles, l’acide polylactique (PLA), l’acrylonitrile butadiène styrène (ABS). Suitable materials for making the applicator 1 by three-dimensional printing are polyamides, photosensitive resins, polylactic acid (PLA), acrylonitrile butadiene styrene (ABS).
L’invention concerne aussi un ensemble applicateur 16 pour produit cosmétique, comprenant le récipient 13 comprenant un corps 17 formant un réservoir destiné à contenir le produit cosmétique (non représenté), et un applicateur 1 , tel que décrit précédemment, adapté pour être fixé sur le récipient 13, de sorte que l’applicateur 1 est logé à l’intérieur du réservoir. L’applicateur 1 est fixé, par exemple, à une extrémité proximale de la tige 3, elle-même fixée à un bouchon 18 avantageusement vissé au récipient 13. The invention also relates to an applicator assembly 16 for a cosmetic product, comprising the container 13 comprising a body 17 forming a reservoir intended to contain the cosmetic product (not shown), and an applicator 1, as described above, adapted to be attached to the cosmetic product. the container 13, so that the applicator 1 is housed inside the reservoir. The applicator 1 is fixed, for example, to a proximal end of the rod 3, itself fixed to a stopper 18 advantageously screwed to the container 13.
De façon avantageuse, le récipient 13 comprend un essoreur 19 fixé à l’intérieur du récipient 13, notamment dans le goulot ou l’orifice d’ouverture 14 du récipient 13. Advantageously, the container 13 comprises a wringer 19 fixed inside the container 13, in particular in the neck or the opening hole 14 of the container 13.
De préférence, le au moins un élément 5, 5A, 5B mobile présente une section transversale au niveau de l’extrémité libre de diamètre inférieur à un diamètre interne de l’essoreur 19. L’applicateur 1 peut ainsi entrer et/ou sortir du récipient 13 sans que le au moins un élément 5, 5A, 5B mobile soit endommagé au moment du passage à travers l’essoreur 19. Preferably, the at least one movable element 5, 5A, 5B has a cross section at the level of the free end of diameter smaller than an internal diameter of the wiper 19. The applicator 1 can thus enter and / or exit the. container 13 without the at least one mobile element 5, 5A, 5B being damaged when passing through the wiper 19.
De façon avantageuse, l’enveloppe E de l’applicateur 1 formée par les extrémités libres 72 des protubérances 7.1 , 7.2, 7.2A, 7.2B présente une section transversale de forme générale circulaire et dont le diamètre maximal est sensible identique au diamètre intérieur de l’essoreur 19. De façon avantageuse, l’anneau 1 1 est dimensionné de manière optimale pour permettre le déplacement angulaire de l’élément 5, 5A, 5B mobile et pour fonctionner avec l’essoreur 19. Advantageously, the envelope E of the applicator 1 formed by the free ends 72 of the protuberances 7.1, 7.2, 7.2A, 7.2B has a cross section of generally circular shape and the maximum diameter of which is substantially identical to the internal diameter of the wringer 19. Advantageously, the ring 1 1 is optimally sized to allow the angular displacement of the mobile element 5, 5A, 5B and to operate with the wiper 19.
Ainsi le passage de l’applicateur 1 à travers l’essoreur 19 permet de retirer le surplus de produit cosmétique mais aussi d’homogénéiser la répartition du produit cosmétique le long de l’âme 2 du fait de la liberté de mouvement de l’élément 5, 5A, 5B mobile, notamment le débattement angulaire. Thus, the passage of the applicator 1 through the wiper 19 makes it possible to remove the surplus of cosmetic product but also to homogenize the distribution of the cosmetic product along the core 2 due to the freedom of movement of the element. 5, 5A, 5B mobile, in particular the angular movement.
