Definitions

  • the invention relates to cosmetic product applicators.
  • a mascara article, or “mascara”, conventionally comprises a case, a reservoir of mascara and an applicator.
  • applicators There are two types of applicators, those of the brush type and those injected.
  • a brush-type applicator forms a brush which comprises bristles formed by fibers trapped in a twisted metal wire forming the core of the applicator.
  • An injected applicator is one piece and has plastic bristles or teeth.
  • Such applicators give satisfactory results for the user. But the user is always looking for new or better makeup effects. For example, the user sometimes seeks a “natural” makeup effect in which the separation of the eyelashes does not have an excessively regular appearance.
  • One object of the invention is therefore to improve cosmetic product applicators.
  • the non-regular arrangement of the supports along the longitudinal axis of the applicator makes it possible to separate the eyelashes also in a non-regular manner.
  • This type of separation is particularly interesting since it makes it possible to obtain a “ruffled” effect and thus gives the impression of denser and more voluminous eyelashes.
  • This non-regularity can for example correspond to supports spaced apart two by two by variable distances along the longitudinal axis of the applicator or else to supports oriented in several different non-parallel directions.
  • the applicator has parts of different configurations which can be used for different respective make-up gestures or make-up modes.
  • One of the parties can, for example, promote the coating of the eyelashes by means of the product, another the separation of the eyelashes or their curling, yet another the fine makeup of certain areas.
  • the number of supports arranged in a non-regular manner may be equal to four, five, six or more.
  • the number of protrusions per support may be at least two. He can by example be three, four, five, six or more.
  • At least one of the supports is different from all the others by a dimension of the support and/or a shape of the support.
  • the supports are all different from one another by a dimension of the support and/or a shape of the support.
  • At least one of the supports has no axis of symmetry and/or no plane of symmetry.
  • the support has no symmetry with respect to the longitudinal axis of the applicator or along a plane radial to this same axis.
  • At least one of the supports has a non-flat face.
  • At least one of the supports has an unregulated surface, all the supports preferably having an unregulated face.
  • the supports have for example at least one concave portion and/or at least one convex portion.
  • At least one of the supports has the general shape of a sheet.
  • These sheets may have a generally wavy shape.
  • their shape may be oblong, cordate (heart-shaped), lanceolate, oval, elliptical, deltoid or webbed.
  • At least one of the supports comprises at least two through openings.
  • the cosmetic product carried by the support can flow through it so as to be distributed homogeneously over several faces of the support and between the different supports.
  • the outline of these openings may have different general shapes.
  • At least a part of at least one of the supports is formed by a ramification of branches, the ramification forming the openings.
  • branches can be elongated and extend outwards from a middle portion of the support. Or that the various branches of a support meet at their distal end in order to form the openings of the support.
  • the supports are distributed in pairs of adjacent supports along the longitudinal axis of the applicator, each support being closer to the support of the same pair than to the other supports.
  • the grouping of the supports leads to the creation of portions of the applicator denser than others in supports and therefore in protrusions carried by these supports.
  • the appearance of alternating portions of the applicator more or less dense in protrusions further increases the irregular appearance of the applicator.
  • the supports follow one another along the longitudinal axis of the applicator and at least two of the supports directly following each other form a cell between them.
  • This cell is capable of containing cosmetic product after the applicator has come out of a reservoir of product.
  • This cell therefore also forms a reserve of product when the applicator is taken out of the reservoir and makes it possible to reduce the number of times that the user is obliged to plunge the applicator back into the reservoir.
  • the volume of this cell depends in particular on the distance which separates the two supports which form it as well as on the size of these supports. Thus, the further apart these two supports are, the greater the volume of the cell will be and vice versa. In addition, the greater the dimension of the two supports, the greater the volume of the cell and vice versa.
  • the cell passes through a longitudinal axis of the applicator.
  • the applicator comprises at least two cells which communicate with each other via at least one opening of one of the supports.
  • the product comprised in these cells is distributed homogeneously between the different cells in order to obtain a better makeup result.
  • the supports have in their middle portion a through opening which facilitates the communication of the two cells between which the opening is located.
  • the protuberances form spines which extend from the support.
  • These thorns that extend the supports have the function of applying mascara to the eyelashes, combing them and separating them. They are, for example, thin and straight or slightly curved. These spines oriented in non-regular directions make it possible to accentuate the disordered effect of the eyelashes. It is of course possible to provide for these thorns to have different shapes, for example hook, zigzag or even helical shapes.
  • the protuberances which extend from the same support do not form a repeating pattern.
  • the protuberances of any one of the supports are not arranged in the same way as the protuberances of the other supports.
  • the applicator has no axis of symmetry and/or no plane of symmetry.
  • the applicator does not include an axis of symmetry along the main longitudinal axis of the applicator and/or does not have symmetry along a longitudinal plane or a horizontal plane. Again, the messy effect is enhanced by this feature.
  • the applicator has no core.
  • the applicator comprises a free end that is thinner than the rest of the applicator.
  • This characteristic facilitates the introduction of the applicator into a case of the cosmetic product article. It also facilitates the make-up of small eyelashes or the execution of corrections during make-up.
  • the applicator has an open cell foam structure.
  • This structure gives the applicator greater flexibility, particularly in bending. This is a flexibility of the entire structure and in particular of the surface envelope of the applicator, like a natural sponge. This flexibility is found particularly at the level of the protuberances, which facilitates make-up.
  • the structure of the applicator can also be described as an open-pore foam structure. This structure is formed by a network of branches which are connected to each other in a punctual manner at points distributed in the volume defined by the external envelope of the brush.

Description

L'invention concerne les applicateurs de produit cosmétique.The invention relates to cosmetic product applicators.

Un article de mascara, ou « mascara », comprend classiquement un étui, un réservoir de mascara et un applicateur. Il existe deux types d'applicateurs, ceux de type goupillon et ceux injectés. Un applicateur de type goupillon forme une brosse qui comprend des poils formés par des fibres emprisonnées dans un fil métallique torsadé formant l'âme de l'applicateur. Un applicateur injecté est d'une seule pièce et comporte des poils ou des dents en matière plastique. De tels applicateurs donnent des résultats satisfaisants pour l'utilisatrice. Mais l'utilisatrice est toujours à la recherche de nouveaux ou de meilleurs effets de maquillage. Par exemple l'utilisatrice recherche parfois un effet de maquillage « naturel » dans lequel la séparation des cils n'a pas un aspect trop régulier.A mascara article, or “mascara”, conventionally comprises a case, a reservoir of mascara and an applicator. There are two types of applicators, those of the brush type and those injected. A brush-type applicator forms a brush which comprises bristles formed by fibers trapped in a twisted metal wire forming the core of the applicator. An injected applicator is one piece and has plastic bristles or teeth. Such applicators give satisfactory results for the user. But the user is always looking for new or better makeup effects. For example, the user sometimes seeks a “natural” makeup effect in which the separation of the eyelashes does not have an excessively regular appearance.

Un but de l'invention est donc d'améliorer les applicateurs de produit cosmétique.One object of the invention is therefore to improve cosmetic product applicators.

A cet effet, on prévoit selon l'invention un applicateur de produit tel que défini dans la revendication 1. Des modes de réalisation préférés sont définis dans les revendications dépendantes.To this end, according to the invention, a product applicator as defined in claim 1 is provided. Preferred embodiments are defined in the dependent claims.

L'arrangement non régulier des supports le long de l'axe longitudinal de l'applicateur permet de séparer les cils d'une manière elle aussi non régulière. Ce type de séparation est particulièrement intéressant puisqu'il permet d'obtenir un effet « ébouriffé » et donne ainsi l'impression de cils plus denses et plus volumineux. Cette non-régularité peut par exemple correspondre à des supports espacés deux à deux par des distances variables le long de l'axe longitudinal de l'applicateur ou alors à des supports orientés dans plusieurs directions différentes non parallèles.The non-regular arrangement of the supports along the longitudinal axis of the applicator makes it possible to separate the eyelashes also in a non-regular manner. This type of separation is particularly interesting since it makes it possible to obtain a “ruffled” effect and thus gives the impression of denser and more voluminous eyelashes. This non-regularity can for example correspond to supports spaced apart two by two by variable distances along the longitudinal axis of the applicator or else to supports oriented in several different non-parallel directions.

De plus, en raison de sa structure non régulière, l'applicateur présente des parties de configurations différentes qui peuvent être utilisées pour des gestes de maquillage ou des modes de maquillage respectifs différents. Une des parties peut par exemple favoriser l'enduction des cils au moyens du produit, une autre la séparation des cils ou leur recourbement, une autre encore le maquillage fin de certaines zones.In addition, due to its non-regular structure, the applicator has parts of different configurations which can be used for different respective make-up gestures or make-up modes. One of the parties can, for example, promote the coating of the eyelashes by means of the product, another the separation of the eyelashes or their curling, yet another the fine makeup of certain areas.

Le nombre de supports agencés de manière non-régulière pourra être égal à quatre, cinq, six ou supérieur.The number of supports arranged in a non-regular manner may be equal to four, five, six or more.

Le nombre de protubérances par support pourra être d'au moins deux. Il pourra par exemple être trois, quatre, cinq, six ou plus.The number of protrusions per support may be at least two. He can by example be three, four, five, six or more.

De préférence, au moins un des supports est différent de tous les autres par une dimension du support et/ou une forme du support.Preferably, at least one of the supports is different from all the others by a dimension of the support and/or a shape of the support.

Cette caractéristique permet d'amplifier le phénomène de non régularité et donc d'améliorer encore le résultat de maquillage. On peut envisager que tous les supports aient la même forme mais qu'ils aient chacun une dimension différente. On peut également envisager que les supports aient tous des formes différentes.This characteristic makes it possible to amplify the phenomenon of non-regularity and therefore to further improve the makeup result. It is possible to envisage that all the supports have the same shape but that they each have a different dimension. It is also possible to envisage that the supports all have different shapes.

De préférence encore, les supports sont tous différents les uns des autres par une dimension du support et/ou une forme du support.Preferably again, the supports are all different from one another by a dimension of the support and/or a shape of the support.

Avantageusement, au moins un des supports ne présente aucun axe de symétrie et/ou aucun plan de symétrie.Advantageously, at least one of the supports has no axis of symmetry and/or no plane of symmetry.

Cette caractéristique amplifie elle aussi le phénomène de séparation non régulière des cils et permet ainsi d'améliorer le résultat de maquillage en donnant aux cils un aspect encore plus volumineux et plus dense. Plus particulièrement, le support ne présente pas de symétrie par rapport à l'axe longitudinal de l'applicateur ou selon un plan radial à ce même axe.This characteristic also amplifies the phenomenon of irregular separation of the eyelashes and thus makes it possible to improve the makeup result by giving the eyelashes an even more voluminous and denser appearance. More particularly, the support has no symmetry with respect to the longitudinal axis of the applicator or along a plane radial to this same axis.

On peut prévoir qu'aucun des supports ne présente d'axe de symétrie et/ou de plan de symétrie.Provision can be made for none of the supports to have an axis of symmetry and/or a plane of symmetry.

On peut prévoir qu'il n'y a pas de symétrie selon un plan perpendiculaire à l'axe entre deux supports de l'applicateur.Provision can be made for there to be no symmetry along a plane perpendicular to the axis between two supports of the applicator.

De préférence, au moins un des supports présente une face non plane.Preferably, at least one of the supports has a non-flat face.

De préférence encore, au moins un des supports présente une surface non réglée, tous les supports présentant de préférence une face non réglée.More preferably, at least one of the supports has an unregulated surface, all the supports preferably having an unregulated face.

Les supports présentent par exemple au moins une portion concave et/ou au moins une portion convexe. Encore une fois, cette caractéristique participe à la séparation non régulière des cils, favorisant ainsi encore le résultat de maquillage décrit précédemment.The supports have for example at least one concave portion and/or at least one convex portion. Once again, this characteristic participates in the non-regular separation of the eyelashes, thus further promoting the make-up result described above.

Avantageusement, au moins un des supports a une forme générale de feuille.Advantageously, at least one of the supports has the general shape of a sheet.

Ces feuilles peuvent présenter une forme générale ondulée. De plus, leur forme pourra être oblongue, cordée (en forme de coeur), lancéolée, ovale, elliptique, deltoïde ou palmée.These sheets may have a generally wavy shape. In addition, their shape may be oblong, cordate (heart-shaped), lanceolate, oval, elliptical, deltoid or webbed.

De manière avantageuse, au moins un des supports comprend au moins deux ouvertures traversantes.Advantageously, at least one of the supports comprises at least two through openings.

Ainsi, le produit cosmétique porté par le support peut s'écouler à travers lui de façon à se répartir de manière homogène sur plusieurs faces du support et entre les différents supports. Le contour de ces ouvertures peut présenter des formes générales différentes. On peut par exemple prévoir des contours de forme ovale, circulaire, rectangulaire, oblongue ou encore des contours n'ayant pas une forme géométrique particulière.Thus, the cosmetic product carried by the support can flow through it so as to be distributed homogeneously over several faces of the support and between the different supports. The outline of these openings may have different general shapes. One can for example provide contours of oval, circular shape, rectangular, oblong or contours that do not have a particular geometric shape.

De préférence, au moins une partie d'au moins un des supports est formée par une ramification de branches, la ramification formant les ouvertures.Preferably, at least a part of at least one of the supports is formed by a ramification of branches, the ramification forming the openings.

On peut prévoir que ces branches sont allongées et s'étendent vers l'extérieur à partir d'une portion médiane du support. Ou encore que les différentes branches d'un support se rejoignent à leur extrémité distale afin de former les ouvertures du support.Provision can be made for these branches to be elongated and extend outwards from a middle portion of the support. Or that the various branches of a support meet at their distal end in order to form the openings of the support.

De manière préférée, les supports sont répartis par paires de supports adjacents le long de l'axe longitudinal de l'applicateur, chaque support étant plus proche du support de la même paire que des autres supports.Preferably, the supports are distributed in pairs of adjacent supports along the longitudinal axis of the applicator, each support being closer to the support of the same pair than to the other supports.

Le groupement des supports entraine la création de portions de l'applicateur plus denses que d'autres en supports et donc en protubérances portées par ces supports. Ainsi, l'apparition d'alternance de portions de l'applicateur plus ou moins denses en protubérances permet encore d'augmenter l'aspect irrégulier de l'applicateur. On peut prévoir que ces groupements comprennent plus que deux supports, par exemple trois, quatre ou cinq. On peut envisager que les supports d'une même paire fusionnent au moins en partie au niveau d'une portion médiane de ceux-ci formant leur jonction.The grouping of the supports leads to the creation of portions of the applicator denser than others in supports and therefore in protrusions carried by these supports. Thus, the appearance of alternating portions of the applicator more or less dense in protrusions further increases the irregular appearance of the applicator. Provision can be made for these groups to comprise more than two supports, for example three, four or five. It is possible to envisage that the supports of the same pair merge at least in part at the level of a middle portion thereof forming their junction.

Les supports se font suite le long de l'axe longitudinal de l'applicateur et au moins deux des supports se faisant directement suite forment entre eux une alvéole.The supports follow one another along the longitudinal axis of the applicator and at least two of the supports directly following each other form a cell between them.

Cette alvéole est apte à contenir du produit cosmétique après que l'applicateur soit sorti d'un réservoir de produit. Cette alvéole forme donc elle aussi une réserve de produit lorsque l'applicateur est sorti du réservoir et permet de réduire le nombre de fois que l'utilisatrice est obligée de replonger l'applicateur dans le réservoir. Le volume de cette alvéole dépend notamment de la distance qui sépare les deux supports qui la forment ainsi que de la dimension de ces supports. Ainsi, plus ces deux supports seront éloignés, plus le volume de l'alvéole sera grand et inversement. En outre, plus la dimension des deux supports sera grande, plus le volume de l'alvéole sera grand et inversement.This cell is capable of containing cosmetic product after the applicator has come out of a reservoir of product. This cell therefore also forms a reserve of product when the applicator is taken out of the reservoir and makes it possible to reduce the number of times that the user is obliged to plunge the applicator back into the reservoir. The volume of this cell depends in particular on the distance which separates the two supports which form it as well as on the size of these supports. Thus, the further apart these two supports are, the greater the volume of the cell will be and vice versa. In addition, the greater the dimension of the two supports, the greater the volume of the cell and vice versa.

L'alvéole traverse un axe longitudinal de l'applicateur.The cell passes through a longitudinal axis of the applicator.

On favorise ainsi une répartition du produit tout autour de l'axe longitudinal de l'applicateur. Cette répartition permet de charger en produit la plus grande partie de l'applicateur et évite une accumulation excessive de produit dans certaines zones de l'applicateur, susceptible d'engendrer le dépôt d'une trop grande quantité de produit sur les cils et l'apparition de paquets.This promotes distribution of the product all around the longitudinal axis of the applicator. This distribution makes it possible to load most of the applicator with product and avoids an excessive accumulation of product in certain areas of the applicator, which could lead to the deposit of too much product on the eyelashes and the eyelashes. appearance of packets.

L'applicateur comprend au moins deux alvéoles qui communiquent entre elles via au moins une ouverture d'un des supports.The applicator comprises at least two cells which communicate with each other via at least one opening of one of the supports.

Ainsi, le produit compris dans ces alvéoles se répartit de manière homogène entre les différentes alvéoles afin d'obtenir un meilleur résultat de maquillage. De préférence, les supports présentent dans leur portion médiane une ouverture traversante qui facilite la mise en communication des deux alvéoles entre lesquelles l'ouverture est située.Thus, the product comprised in these cells is distributed homogeneously between the different cells in order to obtain a better makeup result. Preferably, the supports have in their middle portion a through opening which facilitates the communication of the two cells between which the opening is located.

De préférence, les protubérances forment des épines qui s'étendent à partir du support.Preferably, the protuberances form spines which extend from the support.

Ces épines qui prolongent les supports ont pour fonction d'appliquer le mascara sur les cils, de les peigner et de les séparer. Elles sont par exemple fines et rectilignes ou légèrement courbes. Ces épines orientées dans des directions non régulières permettent d'accentuer l'effet de désordre des cils. On peut bien entendu prévoir que ces épines aient des formes différentes par exemple des formes en crochet, en zigzag ou encore en hélice.These thorns that extend the supports have the function of applying mascara to the eyelashes, combing them and separating them. They are, for example, thin and straight or slightly curved. These spines oriented in non-regular directions make it possible to accentuate the disordered effect of the eyelashes. It is of course possible to provide for these thorns to have different shapes, for example hook, zigzag or even helical shapes.

Avantageusement, les protubérances qui s'étendent à partir d'un même support ne forment pas de motif répétitif.Advantageously, the protuberances which extend from the same support do not form a repeating pattern.

Avantageusement encore, les protubérances de l'un quelconque des supports ne sont pas disposées de la même façon que les protubérances des autres supports.Advantageously again, the protuberances of any one of the supports are not arranged in the same way as the protuberances of the other supports.

Ces deux caractéristiques favorisent elles aussi l'effet de désordre des cils et les avantages qui ont été cités.These two characteristics also promote the effect of disorder of the eyelashes and the advantages which have been cited.

De préférence, l'applicateur ne présente aucun axe de symétrie et/ou aucun plan de symétrie.Preferably, the applicator has no axis of symmetry and/or no plane of symmetry.

Plus particulièrement, l'applicateur ne comprend pas d'axe de symétrie selon l'axe longitudinal principal de l'applicateur et/ou ne présente pas de symétrie selon un plan longitudinal ou un plan horizontal. Encore une fois, l'effet de désordre est amélioré par cette caractéristique.More particularly, the applicator does not include an axis of symmetry along the main longitudinal axis of the applicator and/or does not have symmetry along a longitudinal plane or a horizontal plane. Again, the messy effect is enhanced by this feature.

De manière avantageuse, l'applicateur est dépourvu d'âme.Advantageously, the applicator has no core.

Cette caractéristique donne à l'applicateur une plus grande souplesse, ce qui rend notamment l'application plus agréable pour l'utilisatrice. En outre, dans le cas où l'applicateur présente des alvéoles, la souplesse de l'applicateur due à l'absence d'âme favorise la sortie du produit hors des alvéoles lorsque l'utilisatrice utilise l'applicateur. L'absence d'âme implique que la structure de l'applicateur est autoporteuse.This characteristic gives the applicator greater flexibility, which in particular makes the application more pleasant for the user. Furthermore, in the case where the applicator has cells, the flexibility of the applicator due to the absence of a core promotes the exit of the product from the cells when the user uses the applicator. The absence of a core implies that the structure of the applicator is self-supporting.

De préférence, l'applicateur comprend une extrémité libre amincie par rapport au reste de l'applicateur.Preferably, the applicator comprises a free end that is thinner than the rest of the applicator.

Cette caractéristique permet de faciliter l'introduction de l'applicateur dans un étui de l'article de produit cosmétique. Elle facilite aussi le maquillage des petits cils ou l'exécution de corrections lors du maquillage.This characteristic facilitates the introduction of the applicator into a case of the cosmetic product article. It also facilitates the make-up of small eyelashes or the execution of corrections during make-up.

Avantageusement, l'applicateur a une structure en mousse à cellule ouverte.Advantageously, the applicator has an open cell foam structure.

Cette structure confère à l'applicateur une souplesse plus importante notamment en flexion. Il s'agit d'une souplesse de toute la structure et en particulier de la surface enveloppe de l'applicateur, à la manière d'une éponge naturelle. Cette souplesse se retrouve particulièrement au niveau des protubérances, ce qui facilite le maquillage. On peut également qualifier la structure de l'applicateur de structure en mousse à pores ouverts. Cette structure est formée par un réseau de branches qui sont reliées les unes aux autres de façon ponctuelle en des points répartis dans le volume défini par l'enveloppe externe de la brosse.This structure gives the applicator greater flexibility, particularly in bending. This is a flexibility of the entire structure and in particular of the surface envelope of the applicator, like a natural sponge. This flexibility is found particularly at the level of the protuberances, which facilitates make-up. The structure of the applicator can also be described as an open-pore foam structure. This structure is formed by a network of branches which are connected to each other in a punctual manner at points distributed in the volume defined by the external envelope of the brush.

On peut prévoir que l'applicateur est d'une seule pièce.Provision can be made for the applicator to be in one piece.

La réalisation en une seule pièce présente notamment l'avantage d'être plus rapide à produire. L'applicateur peut être composé d'un matériau unique ou de plusieurs matériaux différents.The production in one piece has the particular advantage of being faster to produce. The applicator can be made of a single material or several different materials.

Plusieurs techniques permettent la réalisation d'un applicateur d'une seule pièce, telles que le moulage par injection ou la synthèse additive.Several techniques allow the production of a one-piece applicator, such as injection molding or additive synthesis.

On peut prévoir aussi selon l'invention un applicateur tel qu'illustré aux figures 3A et 3B.It is also possible according to the invention to provide an applicator as illustrated in figure 3A And 3B .

On prévoit en outre selon l'invention un article de cosmétique comprenant un applicateur tel que décrit précédemment.There is also provided according to the invention a cosmetic article comprising an applicator as described above.

On prévoit également selon l'invention un procédé de fabrication par synthèse additive d'un applicateur tel que décrit précédemment, comprenant les étapes :

  • d'obtention de données relatives à l'applicateur ; et
  • de synthèse additive de l'applicateur au moyen des données.
There is also provided according to the invention a method of manufacturing by additive synthesis of an applicator as described above, comprising the steps:
  • obtaining data relating to the applicator; And
  • of additive synthesis of the applicator by means of the data.

L'avantage de ce mode de fabrication est notamment qu'il permet la réalisation d'applicateurs possédant une structure complexe, qui serait difficile voire impossible à réaliser par injection, compte tenu notamment de l'existence de certaines parties en contre-dépouille.The advantage of this method of manufacture is in particular that it allows the production of applicators having a complex structure, which would be difficult or even impossible to produce by injection, taking into account in particular the existence of certain undercut parts.

Différents procédés de synthèse additive connus de l'homme du métier peuvent être utilisés pour fabriquer l'invention. On peut par exemple citer le frittage sélectif par laser (ou SLS pour Sélective Laser Sintering) et la stéréolithographie (SLA). Un exemple de procédé de fabrication d'un applicateur de produit cosmétique par synthèse additive est décrit dans la demande WO 2008/113939 au nom de la demanderesse.Various additive synthesis methods known to those skilled in the art can be used to manufacture the invention. Mention may be made, for example, of selective laser sintering (or SLS for Selective Laser Sintering) and stereolithography (SLA). An example of a process for manufacturing a cosmetic product applicator by additive synthesis is described in the application WO 2008/113939 on behalf of the plaintiff.

On prévoit également selon l'invention un fichier informatique comprenant des données aptes à être utilisées par un programme d'ordinateur pour commander la mise en oeuvre du procédé tel que décrit précédemment.Provision is also made according to the invention for a computer file comprising data capable of being used by a computer program to control the implementation of the method as described previously.

On prévoit aussi selon l'invention un support d'enregistrement électronique comprenant sous forme enregistrée des données permettant de mettre en oeuvre le procédé tel que décrit précédemment.Provision is also made according to the invention for an electronic recording medium comprising, in recorded form, data making it possible to implement the method as described above.

Enfin, on prévoit également selon l'invention un procédé de mise à disposition d'un fichier tel que décrit précédemment en vue de son téléchargement sur un réseau de télécommunication.Finally, provision is also made according to the invention for a method of making available a file as described previously with a view to downloading it onto a telecommunications network.

Nous allons maintenant présenter un mode de réalisation de l'invention à titre d'exemple non limitatif en référence aux dessins sur lesquels :

  • la figure 1 est une vue en coupe longitudinale schématique d'un article de cosmétique selon un mode de réalisation de l'invention ;
  • la figure 2 est une représentation schématique de l'applicateur de l'article de la figure 1 ;
  • les figures 3A et 3B sont des vues respectivement de côté et en perspective de l'applicateur de l'article des figures 1 et 2 ;
  • la figure 4 est une vue depuis son extrémité libre de l'applicateur des figures 3A et 3B ; et
  • les figures 5A à 5D sont des vues en perspective d'une portion proximale de l'applicateur des figures 3A à 4 montrant une paire de supports.
We will now present an embodiment of the invention by way of non-limiting example with reference to the drawings in which:
  • there figure 1 is a schematic longitudinal sectional view of a cosmetic article according to one embodiment of the invention;
  • there picture 2 is a schematic representation of the applicator section of the figure 1 ;
  • THE figure 3A And 3B are respectively side and perspective views of the applicator of the article of the figures 1 and 2 ;
  • there figure 4 is a view from its free end of the applicator of the figure 3A And 3B ; And
  • THE figures 5A to 5D are perspective views of a proximal portion of the applicator of the figures 3A to 4 showing a pair of brackets.

Nous allons maintenant présenter un mode de réalisation de l'article et du procédé selon l'invention en référence aux figures 1 à 5D. Il sera ici décrit un applicateur de mascara mais on peut bien entendu prévoir l'utilisation de l'applicateur avec un autre produit cosmétique, par exemple du verni à ongles ou du rouge à lèvres.We will now present an embodiment of the article and of the method according to the invention with reference to the figures 1 to 5D . A mascara applicator will be described here but it is of course possible to provide for the use of the applicator with another cosmetic product, for example nail varnish or lipstick.

L'applicateur 1 de mascara décrit dans ce mode de réalisation fait partie d'un article de cosmétique 2 comprenant un capuchon ou bouchon 3, auquel est rigidement lié l'applicateur 1, et un étui 4 comprenant un réservoir de mascara 5 et un essoreur 6 (voir figure 1) logé dans un col du réservoir sur lequel le capuchon peut être fixé, par exemple vissé, de façon amovible pour fermer le réservoir et l'article. L'applicateur s'étend alors dans le réservoir et baigne dans le mascara.The mascara applicator 1 described in this embodiment is part of a cosmetic article 2 comprising a cap or stopper 3, to which the applicator 1 is rigidly attached, and a case 4 comprising a reservoir of mascara 5 and a wiper 6 (see figure 1 ) housed in a neck of the reservoir on which the cap can be fixed, for example screwed, removably to close the reservoir and the article. The applicator then extends into the reservoir and bathes in the mascara.

Bien entendu, d'autres types d'articles avec des applicateurs de mascara peuvent être envisagés comme par exemple des articles de type « stylo » dans lesquels l'applicateur n'est pas lié à un capuchon ou encore des articles dans lesquels l'applicateur ne baigne pas dans la réserve de mascara lorsqu'il n'est pas utilisé.Of course, other types of articles with mascara applicators can be envisaged, for example "pen" type articles in which the applicator is not attached to a cap or even articles in which the applicator does not bathe in mascara reserve when not in use.

L'applicateur est porté par une tige 8 qui le relie au capuchon 3. L'article a une forme générale cylindrique, à section circulaire, carré ou elliptique, et est allongé suivant son axe longitudinal 9. La tige 8 présente une forme générale cylindrique et son axe longitudinal est confondu avec l'axe longitudinal 9 de l'applicateur. La tige et l'applicateur sont liés par une de leurs extrémités (voir figure 3A).The applicator is carried by a rod 8 which connects it to the cap 3. The article has a generally cylindrical shape, with a circular, square or elliptical section, and is elongated along its longitudinal axis 9. The rod 8 has a generally cylindrical shape and its longitudinal axis coincides with the longitudinal axis 9 of the applicator. The rod and the applicator are linked by one of their ends (see Figure 3A ).

L'article peut présenter d'autres formes générales, par exemple une forme générale sphérique, parallélépipédique ou encore cubique.The article may have other general shapes, for example a general spherical, parallelepipedic or even cubic shape.

L'applicateurThe applicator

L'applicateur comprend des supports 10 de protubérances et des protubérances 11. Dans le cas présent, l'applicateur 1 comprend douze supports 10 de protubérances, chacun comprenant entre dix et trente protubérances 11. Bien entendu, le nombre de supports 10 ainsi que le nombre de protubérances peut varier. On peut envisager la présence d'un nombre réduit de supports, par exemple cinq, six, sept, huit, neuf, dix, ou onze, ou d'un nombre plus élevé de support, par exemple quatorze, quinze, seize, dix-sept, dix-huit etc. On peut également envisager qu'un nombre plus important de protubérances soit présent sur un même support, par exemple trente-cinq, quarante ou quarante-cinq, ou un nombre plus faible, par exemple compris entre un et dix.The applicator comprises supports 10 for protrusions and protrusions 11. In the present case, the applicator 1 comprises twelve supports 10 for protrusions, each comprising between ten and thirty protrusions 11. Of course, the number of supports 10 as well as the number of protrusions may vary. It is possible to envisage the presence of a reduced number of supports, for example five, six, seven, eight, nine, ten, or eleven, or of a higher number of supports, for example fourteen, fifteen, sixteen, ten- seven, eighteen etc. It is also possible to envisage a larger number of protuberances being present on the same support, for example thirty-five, forty or forty-five, or a smaller number, for example between one and ten.

Chaque support est plat en l'espèce de façon à présenter deux faces opposées l'une à l'autre. Dans le présent exemple, chaque face est non plane et même non réglée, et présente une ou plusieurs courbures convexes et/ou une ou plusieurs courbures concaves. On peut prévoir qu'un seul ou certains des supports présentent une face non réglée. On peut également prévoir qu'au moins certains des supports soient plans, voire que tous les supports soient plans.Each support is flat in this case so as to present two faces opposite to each other. In the present example, each face is non-planar and even non-regulated, and has one or more convex curvatures and/or one or more concave curvatures. Provision can be made for only one or some of the supports to have an unregulated face. Provision can also be made for at least some of the supports to be flat, or even for all the supports to be flat.

En outre, aucun support ne présente de plan de symétrie ni d'axe de symétrie. Tous les supports sont différents les uns des autres aussi bien par leur forme que par leurs dimensions. On peut bien entendu prévoir que tous les supports soient identiques ou qu'au moins certains des supports soient identiques.In addition, no support has a plane of symmetry or an axis of symmetry. All supports are different from each other both in shape and size. Provision can of course be made for all the supports to be identical or for at least some of the supports to be identical.

Certains des supports ont par exemple une forme de tuile, de selle de cheval, de portion de cylindre, de cône ou encore de tore. Un des supports peut avoir une de ces formes et un autre une autre de ces formes.Some of the supports have for example the shape of a tile, a horse saddle, a portion of a cylinder, a cone or even a torus. One of the supports can have one of these shapes and another another of these shapes.

Dans le cas présent, chaque support 10 est en contact avec au moins un autre support de l'applicateur et forme avec lui une jonction en au moins un point voire le long d'une ligne ou d'une courbe.In the present case, each support 10 is in contact with at least one other support of the applicator and forms with it a junction at at least one point or even along a line or a curve.

Les supports 10 sont disposés le long de l'axe 9 de manière non régulière.The supports 10 are arranged along the axis 9 in a non-regular manner.

Chaque support 10 présente dans une portion médiane une ouverture centrale traversante 12 à partir de laquelle s'étendent plusieurs branches 13. En l'espèce, les ouvertures centrales 12 des supports 10 sont toutes situées le long de l'axe 9. On peut également prévoir qu'au moins une des ouvertures centrales 12 ne soit pas située le long de l'axe 9, voire que toutes les ouvertures centrales 12 ne soient pas situées le long de l'axe 9.Toutes les branches 13 du support sont ramifiées deux à deux de sorte à former entre elles des ouvertures 14 de forme générale ovale allongée. On peut bien entendu prévoir des ouvertures 14 ayant une forme générale différente, par exemple circulaire, rectangulaire, oblongue, ou encore ne possédant aucune forme particulière.Each support 10 has in a middle portion a through central opening 12 from which several branches 13 extend. In this case, the central openings 12 of the supports 10 are all located along the axis 9. provide that at least one of the central openings 12 is not located along the axis 9, or even that all the central openings 12 are not located along the axis 9. All the branches 13 of the support are branched two two so as to form between them openings 14 of generally elongated oval shape. It is of course possible to provide openings 14 having a different general shape, for example circular, rectangular, oblong, or even having no particular shape.

Les supports 10 sont regroupés par paires 15 de supports voisins l'uns de l'autre (voir figures 5A à 5D). Les supports d'une paire sont globalement plus proches l'un de l'autre que des autres paires de supports de l'applicateur. Une paire 15 de supports 10 comprend deux supports qui se suivent directement suivant l'axe 9 et qui fusionnent, c'est-à-dire qu'ils ont une jonction mutuelle, sur au moins une partie de leur portion médiane respective. Dans le cas présent, l'applicateur comprend six paires 15 de supports qui se font suite le long de l'axe 9.The supports 10 are grouped together in pairs 15 of supports neighboring each other (see figures 5A to 5D ). The supports of a pair are generally closer to each other than to the other pairs of supports of the applicator. A pair 15 of supports 10 comprises two supports which follow each other directly along the axis 9 and which merge, that is to say they have a mutual junction, over at least part of their respective middle portion. In the present case, the applicator comprises six pairs 15 of supports which follow one another along the axis 9.

Ici, les supports d'une même paire 15 sont pour la plupart entrelacés. Plus précisément, si on définit une face supérieure et une face inférieure des supports au sein d'une paire 15 comprenant un support proximal et un support distal, une partie du support proximal sera en regard de la face supérieure du support distal et une autre partie du support proximal sera en regard de la face inférieure du support distal. On peut bien entendu prévoir qu'aucune paire 15 n'est composée de supports entrelacés ou que seulement certaines paires le sont. On peut également prévoir des groupements de supports comprenant un nombre différent de supports 10. Par exemple, on peut prévoir des groupements de trois, quatre ou cinq supports qui fusionnent tous ensemble au niveau d'au moins une partie de leur portion médiane.Here, the supports of the same pair 15 are for the most part interleaved. More precisely, if an upper face and a lower face of the supports are defined within a pair comprising a proximal support and a distal support, a part of the proximal support will face the upper face of the distal support and another part of the proximal bracket will face the underside of the distal bracket. It is of course possible to provide that no pair 15 is composed of interleaved supports or that only certain pairs are. It is also possible to provide groups of supports comprising a different number of supports 10. For example, it is possible to provide groups of three, four or five supports which all merge together at the level of at least part of their middle portion.

Deux paires 15 successives définissent entre elles une alvéole 16. L'applicateur comprend ainsi cinq alvéoles 16. L'alvéole est formée par la courbure des supports des paires respectives qui sont en regard l'un de l'autre.Two successive pairs 15 define between them a cell 16. The applicator thus comprises five cells 16. The cell is formed by the curvature of the supports of the respective pairs which are opposite one another.

Chaque alvéole 16 communique avec l'alvéole qui lui fait suite ou la précède directement suivant l'axe 9. Cette communication se fait via les ouvertures 12, 14 des supports qui forment les alvéoles. On peut bien entendu prévoir qu'au moins une des alvéoles 16 ne communique avec aucune autre alvéole. Chaque alvéole traverse l'axe longitudinal 9 et forme ainsi un tunnel. On peut bien entendu prévoir qu'aucune ne traverse l'axe ou qu'une, ou certaines des alvéoles seulement traverse cet axe 9. Dans le cas présent, les directions des alvéoles sont radiales à l'axe 9. On peut prévoir une orientation différente.Each cell 16 communicates with the cell which follows it or directly precedes it along the axis 9. This communication takes place via the openings 12, 14 of the supports which form the cells. It is of course possible to provide that at least one of the cells 16 does not communicate with any other cell. Each cell crosses the longitudinal axis 9 and thus forms a tunnel. One can of course provide that none crosses the axis or that one, or some of the cells only crosses this axis 9. In the present case, the directions of the cells are radial to the axis 9. One can provide an orientation different.

Dans un mode de réalisation alternatif, on peut prévoir que les alvéoles ne soient pas délimitées par deux paires 15 de supports mais simplement par deux supports 10.In an alternative embodiment, it is possible to provide that the cells are not delimited by two pairs 15 of supports but simply by two supports 10.

Comme il a déjà été dit précédemment, chaque support 10 comprend entre dix et trente protubérances 11. Ces protubérances 11 sont de forme générale courbe ou rectiligne et forment ici des épines qui s'étendent à partir du support. Sur un même support 10, au moins une des protubérances 11 possède une forme et/ou une dimension et/ou une orientation différente de celles des autres protubérances. Dans le cas présent, chaque protubérance possède une combinaison de ces caractéristiques (forme, dimension et orientation) unique au sein de l'applicateur. On peut prévoir que plusieurs protubérances aient les mêmes caractéristiques de forme, dimension et orientation au sein d'un applicateur.As has already been said previously, each support 10 comprises between ten and thirty protrusions 11. These protuberances 11 are generally curved or rectilinear in shape and here form thorns which extend from the support. On the same support 10, at least one of the protuberances 11 has a shape and/or a dimension and/or an orientation different from those of the other protuberances. In the present case, each protuberance has a unique combination of these characteristics (shape, dimension and orientation) within the applicator. We can predict that several protrusions have the same shape, size and orientation characteristics within an applicator.

Certaines protubérances, voire toutes, pourraient être formées par des doigts, des poils ou des brins plutôt que par des épines.Some, if not all, protuberances could be formed by fingers, hairs, or twigs rather than spines.

Les caractéristiques qui précèdent donnent à l'applicateur du présent exemple une forme désordonnée, irrégulière et ébouriffée. On observe en particulier que les supports, tout comme les protubérances, s'étendent respectivement dans toutes les directions. Il en est de même pour les alvéoles. On remarque aussi qu'il présente de nombreuses faces en contre-dépouille.The foregoing characteristics give the applicator of the present example a messy, irregular and ruffled shape. It is observed in particular that the supports, like the protuberances, extend respectively in all directions. The same is true for the cells. We also notice that it has many undercut faces.

L'applicateur est dépourvu d'âme, ce qui lui confère une grande souplesse et rend ainsi l'application plus agréable pour l'utilisatrice. Cette souplesse favorise la sortie du produit hors des alvéoles lorsque l'utilisatrice utilise l'applicateur. L'absence d'âme implique que la structure de l'applicateur est autoporteuse.The applicator has no core, which gives it great flexibility and thus makes application more pleasant for the user. This flexibility promotes the exit of the product from the cells when the user uses the applicator. The absence of a core implies that the structure of the applicator is self-supporting.

Utilisation de l'applicateurUse of the applicator

Dans un premier temps, l'utilisatrice manipule l'applicateur 1 en tenant le capuchon 3 entre ses doigts et plonge l'applicateur 1 dans la réserve de mascara 5 de l'article 2. Lors de cette étape, les alvéoles 16, les ouvertures 12, 14 ainsi que les supports 10 et les protubérances 11 se chargent en mascara.Initially, the user manipulates the applicator 1 while holding the cap 3 between her fingers and immerses the applicator 1 in the reserve of mascara 5 of the article 2. During this step, the cells 16, the openings 12, 14 as well as the supports 10 and the protrusions 11 are loaded with mascara.

Lors de la sortie de l'applicateur hors du réservoir et donc de son passage à travers l'essoreur 6, l'applicateur est essoré mais les alvéoles conservent tout ou partie de cette réserve de mascara. Cet essorage contribue aussi à répartir le produit dans et sur l'applicateur, le produit pouvant traverser les ouvertures et les alvéoles.When the applicator leaves the reservoir and therefore passes through wiper 6, the applicator is wrung out but the cells retain all or part of this reserve of mascara. This wiping also contributes to distributing the product in and on the applicator, the product being able to pass through the openings and the cells.

Lors de l'utilisation, l'utilisatrice approche l'applicateur de ses cils afin de les maquiller et utilise pour cela un mouvement de maquillage classique, essentiellement vertical. Le mascara présent sur les épines 11 et sur les supports 10 est ainsi déposé sur les cils. Les épines 11 ainsi que les bords des supports 10 lissent ce mascara déposé afin d'éviter la formation de paquets et assurent également une fonction de peignage des cils. Comme chaque épine, ainsi que chaque support, présente des dimensions et/ou des orientations et/ou des formes différentes, on obtient un peignage des cils dans des directions différentes qui favorise l'effet « ébouriffé » recherché.During use, the user brings the applicator closer to her eyelashes in order to make them up and uses a conventional, essentially vertical make-up movement for this purpose. The mascara present on the spines 11 and on the supports 10 is thus deposited on the eyelashes. The thorns 11 as well as the edges of the supports 10 smooth this deposited mascara in order to avoid the formation of clumps and also perform a function of combing the eyelashes. Since each spine, as well as each support, has different dimensions and/or orientations and/or shapes, the eyelashes are combed in different directions, which promotes the desired “disheveled” effect.

Lors de l'application, l'applicateur se comporte comme une éponge du fait de sa souplesse et rejette du mascara dans les zones de contact, c'est-à-dire dans les zones d'application, ce qui facilite le maquillage en réduisant notamment le nombre de fois où l'utilisatrice doit replonger l'applicateur dans le réservoir en orientant le mascara dans les endroits où il y en a besoin.During application, the applicator behaves like a sponge due to its flexibility and rejects mascara in the contact zones, that is to say in the application zones, which facilitates makeup by reducing in particular the number of times the user has to dip the applicator back into the reservoir, directing the mascara in the places where it is needed.

Plus précisément, lorsque l'applicateur 1 est pressé contre une zone des cils, il se comprime localement du fait de sa souplesse. Le mascara présent dans une alvéole 16 à proximité de cette zone de compression est dirigé de ce fait vers la zone d'application. Ce mascara peut notamment se répandre, depuis son alvéole 16, sur le ou les supports 10 formant l'alvéole puis sur les épines 11 et est ainsi disponible pour l'application. Les ouvertures 14, 12 des supports permettent également au mascara de se répandre de support en support au sein de l'applicateur, cela permettant notamment de mobiliser du mascara qui est relativement éloigné de la zone d'application.More precisely, when the applicator 1 is pressed against an area of the eyelashes, it compresses locally due to its flexibility. The mascara present in a cell 16 close to this compression zone is therefore directed towards the application zone. This mascara can in particular spread, from its cell 16, on the support or supports 10 forming the cell then on the thorns 11 and is thus available for application. The openings 14, 12 of the supports also allow the mascara to spread from support to support within the applicator, this notably making it possible to mobilize mascara which is relatively far from the application zone.

Le procédé de fabricationThe manufacturing process

L'applicateur présenté ci-dessus est fabriqué d'une seule pièce. Plus particulièrement, cet applicateur est ici fabriqué par synthèse additive, aussi appelé impression tridimensionnelle.The applicator shown above is made in one piece. More particularly, this applicator is here manufactured by additive synthesis, also called three-dimensional printing.

Toute matière appropriée convient pour réaliser l'applicateur. Cela peut être une matière plastique par exemple un polyamide, notamment un polyamide 1102, un PEBA 2301, ou bien une résine de type ABS, ou encore un métal en poudre tel qu'un acier inoxydable ou du titane.Any appropriate material is suitable for making the applicator. This may be a plastic material, for example a polyamide, in particular a polyamide 1102, a PEBA 2301, or else an ABS-type resin, or even a powdered metal such as stainless steel or titanium.

La matière peut être rigide mais sera de préférence élastiquement flexible. Il est préférable que la matière, en association avec les caractéristiques de forme de l'applicateur, lui donne une certaine souplesse, en particulier au niveau des supports et surtout des protubérances.The material may be rigid but will preferably be elastically flexible. It is preferable that the material, in association with the characteristics of the shape of the applicator, give it a certain flexibility, in particular at the level of the supports and especially of the protrusions.

On rappelle qu'un applicateur de mascara a généralement une longueur inférieure à 20 mm.It is recalled that a mascara applicator generally has a length of less than 20 mm.

Plusieurs procédés de synthèse additive peuvent être utilisés pour la réalisation d'un applicateur tel que décrit précédemment. On peut citer notamment le frittage sélectif par laser à partir de matière en poudre et la stéréolithographie (SLA). Dans le cas présent, un procédé de frittage sélectif par laser est utilisé, ce procédé présentant l'avantage de permettre la fabrication d'objets ayant une forme complexe.Several additive synthesis methods can be used to produce an applicator as described previously. Mention may in particular be made of selective laser sintering from powdered material and stereolithography (SLA). In the present case, a selective laser sintering process is used, this process having the advantage of allowing the manufacture of objects having a complex shape.

L'applicateur est dans un premier temps conçu sur un logiciel de conception assisté par ordinateur (CAO). Un fichier au format STL comprenant les données de conception de l'applicateur ainsi conçu est ensuite exporté. Ces données déterminent la forme de l'applicateur. D'autres formats de fichier standards pour la synthèse additive peuvent être utilisés.The applicator is initially designed using computer-aided design (CAD) software. A file in STL format comprising the design data of the applicator thus designed is then exported. These data determine the shape of the applicator. Other standard file formats for additive synthesis can be used.

Ce fichier est ensuite traité par un logiciel fourni par le constructeur de la machine utilisée pour réaliser la synthèse additive. Ce logiciel découpe en sections le fichier sous la forme d'une centaine d'images numériques au format SLI ou BFF, chacune d'elles correspondant à une couche du modèle à imprimer, c'est-à-dire à une section de l'applicateur prise dans un plan perpendiculaire à l'axe 9. Ces données sont ensuite transmises à l'imprimante afin qu'elle produise l'applicateur.This file is then processed by software provided by the manufacturer of the machine used to perform the additive synthesis. This software cuts the file into sections in the form of a hundred digital images in SLI or BFF format, each of them corresponding to a layer of the model to be printed, i.e. to a section of the applicator taken in a plane perpendicular to axis 9. These data are then transmitted to the printer to produce the applicator.

Une fois la synthèse terminée, des traitements peuvent être appliqués à l'applicateur afin par exemple d'en améliorer l'aspect.Once the synthesis is complete, treatments can be applied to the applicator in order, for example, to improve its appearance.

Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci.Of course, many modifications may be made to the invention without departing from the scope thereof.

Le mode de réalisation présenté ci-dessus concerne les applicateurs de mascara mais on peut appliquer ces caractéristiques à d'autres types d'applicateur de produit cosmétique tels que des applicateurs de vernis à ongles ou des applicateurs de produit cosmétique pour les sourcils ou les cheveux.The embodiment presented above relates to mascara applicators but these characteristics can be applied to other types of cosmetic product applicator such as nail varnish applicators or cosmetic product applicators for the eyebrows or the hair .

On peut prévoir un applicateur dans lequel les supports sont répartis de manière régulière mais sur lesquels les protubérances sont réparties de manière non régulière.It is possible to provide an applicator in which the supports are distributed in a regular manner but on which the protrusions are distributed in a non-regular manner.

On peut également prévoir un applicateur dans lequel les supports sont identiques et présentent chacun la même organisation de protubérances, ces supports étant répartis de manière non régulière le long de l'axe longitudinal de l'applicateur.It is also possible to provide an applicator in which the supports are identical and each have the same organization of protrusions, these supports being distributed unevenly along the longitudinal axis of the applicator.

On peut également prévoir que l'applicateur comprend une structure d'exosquelette.Provision can also be made for the applicator to comprise an exoskeleton structure.

On peut prévoir un applicateur comprenant des supports présentant au moins trois ouvertures possédant chacune une direction principale d'ouverture différente.It is possible to provide an applicator comprising supports having at least three openings each having a different main direction of opening.
