Description

L'invention concerne un applicateur pour produit cosmétique et un ensemble applicateur associé.The invention relates to an applicator for a cosmetic product and an associated applicator assembly.

On connait des applicateurs pour produit cosmétique, notamment destiné à être appliqué sur les cils tel que du mascara, comprenant une âme s'étendant suivant une direction longitudinale principale et une pluralité de protubérances répartie le long de l'âme et faisant saillie depuis ladite âme.Applicators are known for a cosmetic product, in particular intended to be applied to the eyelashes such as mascara, comprising a core extending in a main longitudinal direction and a plurality of protuberances distributed along the core and projecting from said core. .

De manière classique, l'applicateur comprend des zones présentant une plus grande souplesse afin d'obtenir, au niveau de ces zones, une plus grande précision lors de l'application du produit cosmétique. Pour cela, il est par exemple connu d'attribuer à ces zones des protubérances de plus grande longueur et donc de plus grande souplesse.Conventionally, the applicator comprises zones exhibiting greater flexibility in order to obtain, at these zones, greater precision during the application of the cosmetic product. For this, it is for example known to assign these areas protuberances of greater length and therefore greater flexibility.

De telles protubérances sont efficaces pour peigner les cils, notamment car elles permettent de séparer les cils les uns des autres et de les allonger, lors de l'application du produit cosmétique.Such protuberances are effective for combing the eyelashes, in particular because they make it possible to separate the eyelashes from one another and to lengthen them, during the application of the cosmetic product.

Or, de telles protubérances sont souvent trop essorées, lorsque l'applicateur est extrait du récipient comprenant le produit cosmétique et que le goulot muni d'un essoreur dudit récipient essore la pluralité de protubérances dudit applicateur. Les protubérances les plus longues se trouvent donc souvent insuffisamment chargées en produit cosmétique de sorte qu'après application du produit cosmétique, les cils peuvent manquer de volume.However, such protuberances are often too wrung out, when the applicator is extracted from the container comprising the cosmetic product and the neck provided with a wringer of said container wrings out the plurality of protuberances of said applicator. The longest protuberances are therefore often insufficiently loaded with cosmetic product so that after application of the cosmetic product, the eyelashes may lack volume.

Il existe plusieurs solutions pour augmenter la flexibilité d'un applicateur et/ou le stockage en produit cosmétique.There are several solutions for increasing the flexibility of an applicator and / or the storage of cosmetic product.

Par exemple, le document FR3 004 906 divulgue un applicateur comportant une âme ayant une pluralité de gorges qui augmentent sa flexibilité et le document FR3 018 436 divulgue un applicateur comportant une âme présentant au moins une zone de flexion.For example, the document FR3 004 906 discloses an applicator comprising a core having a plurality of grooves which increase its flexibility and the document FR3 018 436 discloses an applicator comprising a core having at least one flexion zone.

Dans un autre exemple, le document FR3 017 782 divulgue un applicateur comprenant une âme et une pluralité de protubérances formant au moins une rangée de plateaux formant des interstices angulaire entre lesdits plateaux.In another example, the document FR3 017 782 discloses an applicator comprising a core and a plurality of protuberances forming at least one row of trays forming angular interstices between said trays.

La présente invention a pour but de proposer une solution alternative pour créer des zones de souplesse le long de l'applicateur.The object of the present invention is to propose an alternative solution for creating zones of flexibility along the applicator.

Ainsi, l'invention concerne un applicateur pour produit cosmétique comprenant une âme s'étendant suivant une direction d'extension longitudinale principale, dite direction principale, et une pluralité de protubérances faisant saillie à partir de l'âme.Thus, the invention relates to an applicator for a cosmetic product comprising a core extending in a main longitudinal direction of extension, called main direction, and a plurality of protrusions protruding from the core.

Selon l'invention, l'âme comprend une pluralité de zones de souplesse successivement agencées le long de la direction principale, au niveau desquelles l'âme est amincie suivant un axe d'amincissement sensiblement orthogonal par rapport à la direction principale de sorte à former deux cavités radialement opposées par rapport à ladite direction principale, l'applicateur comprenant au moins une zone de souplesse présentant un axe d'amincissement décalé angulairement par rapport à l'axe d'amincissement d'une zone de souplesse qui lui est adjacente.According to the invention, the core comprises a plurality of zones of flexibility successively arranged along the main direction, at the level of which the core is thinned along a substantially orthogonal thinning axis by relative to the main direction so as to form two radially opposite cavities with respect to said main direction, the applicator comprising at least one zone of flexibility having a thinning axis angularly offset with respect to the thinning axis of a zone of flexibility which is adjacent to it.

Les zones de souplesse ménagées sur l'âme permettent de conférer de la souplesse aux protubérances agencées au niveau desdites zones de souplesse sans qu'il soit nécessaire de jouer sur la longueur desdites protubérances. Ainsi, il est possible d'appliquer le produit cosmétique avec plus de précision au niveau des zones de souplesse, tout en s'assurant que les protubérances sont suffisamment chargées en produit cosmétique. Autrement dit, les protubérances qui se trouvent au niveau de ces zones n'ont pas à présenter une longueur trop grande pour assurer la souplesse recherchée. Encore autrement dit, les protubérances qui se trouvent au niveau de ces zones n'ont pas à être allongées pour assurer la souplesse recherchée.The zones of flexibility provided on the core make it possible to confer flexibility on the protuberances arranged at the level of said zones of flexibility without it being necessary to play on the length of said protuberances. Thus, it is possible to apply the cosmetic product with more precision in the areas of flexibility, while ensuring that the protuberances are sufficiently loaded with cosmetic product. In other words, the protuberances which are located at these zones do not have to have too great a length to ensure the desired flexibility. In other words, the protuberances which are located at the level of these zones do not have to be lengthened to ensure the desired flexibility.

Cela permet de peigner les cils tout en leur donnant du volume, lors de l'application du produit cosmétique.This makes it possible to comb the eyelashes while giving them volume, during the application of the cosmetic product.

Par ailleurs, les cavités réalisées par amincissement de l'âme au niveau desdites zones de souplesse forment des réservoirs à produit cosmétique. Cela participe également à assurer une charge suffisante des protubérances, lors de l'application du produit cosmétique.Furthermore, the cavities produced by thinning the core at the level of said zones of flexibility form cosmetic product reservoirs. This also helps to ensure a sufficient load of the protuberances, during the application of the cosmetic product.

En outre, le fait de décaler angulairement, d'une zone de souplesse à une autre, l'amincissement réalisé au niveau desdites zones de souplesse a pour effet d'obtenir, suivant la direction principale, une âme flexible autour de différents axes de flexion. Cela a pour avantage de ne pas obliger un utilisateur à donner à l'applicateur une orientation initiale spécifique avant d'appliquer le produit cosmétique. Autrement dit, l'utilisateur n'a pas à apprendre une nouvelle gestuelle pour utiliser cet applicateur.In addition, the fact of angularly shifting, from one zone of flexibility to another, the thinning carried out at the level of said zones of flexibility has the effect of obtaining, in the main direction, a flexible core around different axes of flexion. . This has the advantage of not requiring a user to give the applicator a specific initial orientation before applying the cosmetic product. In other words, the user does not have to learn a new gesture to use this applicator.

The invention will be better understood, and other aims, details, characteristics and advantages thereof will emerge more clearly in the course of the detailed explanatory description which follows, of at least one embodiment of the invention given to by way of purely illustrative and non-limiting example, with reference to the appended schematic drawings.
On these drawings:

Les figures 1 à 4 et 5a, 5b montrent un applicateur 10 pour produit cosmétique selon un mode de réalisation de l'invention. Le produit cosmétique est notamment destiné à être appliqué sur les cils tel que du mascara.The figures 1 to 4 and 5a, 5b show an applicator 10 for a cosmetic product according to one embodiment of the invention. The cosmetic product is intended in particular to be applied to the eyelashes, such as mascara.

L'applicateur 10 comprend une âme 11 s'étendant suivant une direction d'extension longitudinale principale X, dite direction principale X, et une pluralité de protubérances 12 faisant saillie à partir de l'âme 11. On entend par « protubérances faisant saillie à partir de l'âme » que les protubérances 12 comprennent une base se situant au niveau de l'âme 11 et qui s'étendent en direction d'une extrémité libre 24 opposée.The applicator 10 comprises a core 11 extending in a main longitudinal direction of extension X, referred to as the main direction X, and a plurality of protuberances 12 projecting from the core 11. The term “protrusions protruding from the core 11” is understood to mean. from the web ”that the protrusions 12 include a base lying at the level of the web 11 and which extend in the direction of an opposite free end 24.

L'âme 11 comprend en outre une pluralité de zones de souplesse 13a, 13b successivement agencées le long de la direction principale X, au niveau desquelles l'âme 11 est amincie suivant un axe d'amincissement 14a, 14b sensiblement orthogonal par rapport à la direction principale X de sorte à former deux cavités 15a, 15b radialement opposées par rapport à ladite direction principale X. (voir figures 1, 2 et 4).The core 11 further comprises a plurality of flexibility zones 13a, 13b successively arranged along the main direction X, at the level of which the core 11 is thinned along a thinning axis 14a, 14b substantially orthogonal with respect to the main direction X so as to form two cavities 15a, 15b radially opposed with respect to said main direction X. (see figures 1 , 2 and 4 ).

Autrement dit, au niveau de chaque zone de souplesse 13a, 13b, l'âme 11 est amincie suivant un axe d'amincissement 14a, 14b. Cet amincissement est réalisé, suivant l'axe d'amincissement 14a, 14b, aussi bien d'un côté que de l'autre de la direction principale X formant ainsi les deux cavités 15a, 15b. Encore autrement dit, au niveau de chaque zone de souplesse 13a, 13b, l'âme 11 est amincie de manière globalement symétrique de part et d'autre de la direction principale X.In other words, at each zone of flexibility 13a, 13b, the core 11 is thinned along a thinning axis 14a, 14b. This thinning is carried out, along the thinning axis 14a, 14b, both on one side and the other of the main direction X, thus forming the two cavities 15a, 15b. In other words, at the level of each zone of flexibility 13a, 13b, the core 11 is thinned in a generally symmetrical manner on either side of the main direction X.

De cette manière, l'âme 11 est plus souple au niveau des cavités 15a, 15b des zones de souplesse 13a, 13b, cette souplesse étant transmise aux protubérances 12 agencées au niveau desdites cavités 15a, 15b afin notamment d'appliquer le produit cosmétique avec plus de précision au niveau de ces zones de souplesse 13a, 13b. Ainsi, il est possible d'augmenter localement la précision de l'applicateur 10 sans toutefois augmenter la longueur des protubérances 12 pour en augmenter la souplesse et donc sans perdre en charge de produit cosmétique sur lesdites protubérances 12. L'applicateur 10 permet donc à la fois de peigner les cils et de leur donner du volume, lors de l'application du produit cosmétique. En outre, les cavités 15a, 15b forment des réservoirs de produit cosmétique, permettant ainsi de charger davantage les protubérances 12 en produit cosmétique en vue de donner plus de volume aux cils, lors de l'application dudit produit cosmétique.In this way, the core 11 is more flexible at the level of the cavities 15a, 15b of the zones of flexibility 13a, 13b, this flexibility being transmitted to the protuberances 12 arranged at the level of said cavities 15a, 15b in order in particular to apply the cosmetic product with more precision at the level of these zones of flexibility 13a, 13b. Thus, it is possible to locally increase the precision of the applicator 10 without, however, increasing the length of the protuberances 12 in order to increase their flexibility and therefore without losing the load of cosmetic product on said protuberances 12. The applicator 10 therefore allows both combing the eyelashes and giving them volume, during the application of the cosmetic product. In addition, the cavities 15a, 15b form cosmetic product reservoirs, thus making it possible to load the protuberances 12 more with cosmetic product in order to give more volume to the eyelashes, during the application of said cosmetic product.

L'une au moins des zones de souplesse 13a, 13b présente un axe d'amincissement 14a, 14b décalé angulairement, autour de la direction principale X, par rapport à l'axe d'amincissement 14b, 14a d'une zone de souplesse 13b, 13a qui lui est adjacente. On entend par « décalés angulairement » le fait que lesdits axes d'amincissement 14a, 14b forment ensemble un angle de décalage α non nul et strictement inférieur à 180°. L'angle de décalage α est visible sur les figures 3 et 4. On entend encore par « décalés angulairement » le fait que lesdits axes d'amincissement 14a, 14b ne sont pas parallèles entre eux.At least one of the flexibility zones 13a, 13b has a thinning axis 14a, 14b angularly offset, around the main direction X, with respect to the thinning axis 14b, 14a of a flexibility zone 13b , 13a which is adjacent to it. The term “angularly offset” is understood to mean the fact that said thinning axes 14a, 14b together form a non-zero offset angle α which is strictly less than 180 °. The offset angle α is visible on the figures 3 and 4 . The term “angularly offset” also means the fact that said thinning axes 14a, 14b are not mutually parallel.

De cette manière, l'âme 11 présente des zones de souplesse 13a, 13b qui peuvent chacune fléchir autour d'un axe 22, dit axe transversal, orthogonal à la direction principale X et à l'axe d'amincissement 14a, 14b associé à ladite zone de souplesse 13a, 13b, ces axes transversaux 22 pouvant être différents d'une zone de souplesse 13a, 13b à une autre. Ainsi, il n'est pas nécessaire de donner à l'applicateur 10 une orientation initiale spécifique avant d'appliquer le produit cosmétique, l'applicateur 10 étant flexible, le long de l'âme 11, autour de plusieurs axes transversaux 22. L'utilisateur de l'applicateur de l'invention n'a donc pas à adapter sa gestuelle habituelle.In this way, the core 11 has zones of flexibility 13a, 13b which can each flex around an axis 22, said transverse axis, orthogonal to the main direction X and to the thinning axis 14a, 14b associated with said zone of flexibility 13a, 13b, these transverse axes 22 possibly being different from one zone of flexibility 13a, 13b to another. Thus, it is not necessary to give the applicator 10 a specific initial orientation before applying the cosmetic product, the applicator 10 being flexible, along the core 11, around several transverse axes 22. L The user of the applicator of the invention therefore does not have to adapt his usual gestures.

L'âme 11 est ici représentée pleine. Elle pourra cependant être creuse sans sortir du cadre de l'invention.The core 11 is here represented full. It may however be hollow without departing from the scope of the invention.

L'âme 11 comprend, suivant la direction principale X, une extrémité proximale 16 prolongée par un manchon 17 dépourvu de protubérances et une extrémité distale 18 opposée à la portion proximale 16. Le manchon 17 est destiné à coopérer avec une tige (non illustrée). L'extrémité distale 18 comprend une extrémité libre 20. L'extrémité libre 20 présente par exemple une surface plane 21 agencée perpendiculairement à la direction principale X. L'extrémité libre 20 est dépourvue de protubérances 12.The core 11 comprises, in the main direction X, a proximal end 16 extended by a sleeve 17 devoid of protuberances and a distal end 18 opposite to the proximal portion 16. The sleeve 17 is intended to cooperate with a rod (not shown) . The distal end 18 comprises a free end 20. The free end 20 has for example a flat surface 21 arranged perpendicular to the main direction X. The free end 20 is devoid of protrusions 12.

En variante, l'extrémité libre 20 pourra présenter des protubérances 12.As a variant, the free end 20 may have protrusions 12.

L'âme 11 peut comprendre une succession de zones de souplesse 13a, 13b présentant des axes d'amincissement 14a, 14b qui sont décalés angulairement les uns par rapport aux autres, autour de la direction principale X.The core 11 can comprise a succession of zones of flexibility 13a, 13b having thinning axes 14a, 14b which are angularly offset with respect to each other, around the main direction X.

L'âme 11 comprend par exemple une alternance de premières zones de souplesse 13a dont les axes d'amincissement 14a sont parallèles entre eux et de deuxièmes zones de souplesse 13b dont les axes d'amincissement 14b sont parallèles entre eux et décalés angulairement par rapport aux axes d'amincissement 14a des premières zones de souplesse 13a, autour de la direction principale X (figures 1, 2, 3, 4, 5a et 5b).The core 11 comprises for example an alternation of first zones of flexibility 13a whose thinning axes 14a are mutually parallel and of second zones of flexibility 13b whose thinning axes 14b are parallel to each other and angularly offset with respect to each other. thinning axes 14a of the first flexibility zones 13a, around the main direction X ( figures 1 , 2 , 3 , 4 , 5a and 5b ).

A titre d'exemple, une zone de souplesse sur deux, suivant la direction principale X, est une première zone de souplesse 13a et une zone de souplesse sur deux, suivant la direction principale X, est une deuxième zone de souplesse 13b. D'autres motifs de premières et de deuxièmes zones de souplesse 13a, 13b peuvent être prévus sans sortir du cadre de l'invention. On pourra notamment avoir une succession d'au moins deux premières zones de souplesse 13a avec une ou plusieurs deuxièmes zones de souplesse 13b.By way of example, every second zone of flexibility, along the main direction X, is a first zone of flexibility 13a and every second zone of flexibility, along the main direction X, is a second zone of flexibility 13b. Other patterns of first and second zones of flexibility 13a, 13b can be provided without departing from the scope of the invention. In particular, it is possible to have a succession of at least two first zones of flexibility 13a with one or more second zones of flexibility 13b.

L'angle de décalage α entre les axes d'amincissement 14a, 14b des premières et deuxièmes zones de souplesse 13a, 13b est par exemple compris entre 45 et 135°. De préférence, l'angle de décalage α est de l'ordre de 90° (figures 1, 2, 4, 5a et 5b). Autrement dit, l'âme 11 comprend de préférence une alternance de zones de souplesse 13a, 13b présentant des axes d'amincissement 14a, 14b orthogonaux entre eux.The offset angle α between the thinning axes 14a, 14b of the first and second flexibility zones 13a, 13b is for example between 45 and 135 °. Preferably, the offset angle α is of the order of 90 ° ( figures 1 , 2 , 4 , 5a and 5b ). In other words, the core 11 preferably comprises an alternation of zones of flexibility 13a, 13b having thinning axes 14a, 14b which are orthogonal to one another.

Cela est illustré à l'aide des figures 5a et 5b qui illustrent chacune une section de l'âme 11 le long de la direction principale X, en deux endroits distincts le long de cette direction X - voir la figure 2 pour le positionnement de l'axe de coupe A-A (figure 5a) et pour celui de la coupe B-B (figure 5b). La figure 5a illustre une coupe en forme sensiblement rectangulaire dont le plus grand côté s'étend le long de l'axe 14b ; tandis que la figure 5b illustre une coupe sensiblement rectangulaire dont le plus grand côté s'étend le long de l'axe 14a, ces deux axes étant ici orthogonaux.This is illustrated using the figures 5a and 5b which each illustrate a section of the web 11 along the main direction X, in two distinct places along this direction X - see figure 2 for positioning the cutting axis AA ( figure 5a ) and for that of the BB cut ( figure 5b ). The figure 5a illustrates a section in substantially rectangular shape, the longer side of which extends along the axis 14b; while the figure 5b illustrates a substantially rectangular section, the largest side of which extends along the axis 14a, these two axes being here orthogonal.

Les zones de souplesse 13a, 13b peuvent être localisées sur une portion discrète de la direction principale X de l'âme 11. Autrement dit, les zones de souplesse 13a, 13b peuvent être localisées sur une partie seulement de l'âme 11. Les zones de souplesse 13a, 13b sont par exemple localisées sur une portion de l'âme 11 (modes de réalisation non illustrés ici).The zones of flexibility 13a, 13b can be located on a discrete portion of the main direction X of the core 11. In other words, the zones of flexibility 13a, 13b can be located on only part of the core 11. The zones of flexibility 13a, 13b are for example located on a portion of the core 11 (embodiments not illustrated here).

Par exemple, elles peuvent être localisées sur première portion P1 de l'âme 11, qui s'étend à partir de l'extrémité distale 18 de l'âme 11 vers l'extrémité proximale 16 l'âme 11 sur une distance n'excédant pas la moitié de la longueur de l'âme 11 (voir figure 2 pour le repère des zones P1, P2 et P3).For example, they can be located on the first portion P1 of the core 11, which extends from the distal end 18 of the core 11 towards the proximal end 16 the core 11 over a distance not exceeding not half the length of the web 11 (see figure 2 for the marking of zones P1, P2 and P3).

Elles peuvent aussi être localisées sur seconde portion P2 de l'âme 11, qui s'étend entre l'extrémité distale 18 de l'âme 11 et l'extrémité proximale 16 l'âme 11 sur une distance n'excédant pas la moitié de la longueur de l'âme 11.They can also be located on the second portion P2 of the core 11, which extends between the distal end 18 of the core 11 and the proximal end 16 the core 11 over a distance not exceeding half of web length 11.

Elles peuvent aussi être localisées sur troisième portion P3 de l'âme 11, qui s'étend à partir de l'extrémité proximale 16 de l'âme 11 vers l'extrémité distale 18 de l'âme 11 sur une distance n'excédant pas la moitié de la longueur de l'âme 11.They can also be located on the third portion P3 of the core 11, which extends from the proximal end 16 of the core 11 towards the distal end 18 of the core 11 over a distance not exceeding half the length of the web 11.

Elles peuvent encore résulter d'une combinaison des exemples précités, ceci sans sortir du cadre de l'invention ; à savoir, être localisées sur les première et seconde portions P1, P2, sur les première et troisième portions P1, P3 et/ou sur les seconde et troisième portions P2, P3.They can also result from a combination of the aforementioned examples, without departing from the scope of the invention; namely, to be located on the first and second portions P1, P2, on the first and third portions P1, P3 and / or on the second and third portions P2, P3.

Les cavités 15a, 15b formées par l'amincissement de l'âme 11 sont par exemple symétriques par rapport à un plan sensiblement orthogonal à l'axe d'amincissement 14a, 14b qui leur est associé et comprenant la direction principale X.The cavities 15a, 15b formed by the thinning of the core 11 are for example symmetrical with respect to a plane substantially orthogonal to the thinning axis 14a, 14b which is associated with them and comprising the main direction X.

Les cavités 15a, 15b peuvent en outre être concaves suivant la direction principale X.The cavities 15a, 15b can also be concave in the main direction X.

Les cavités 15a, 15b peuvent aussi présenter une forme polygonale, par exemple triangulaire ou encore carrée ou rectangulaire, suivant la direction principale X. Les arêtes des cavités 15a, 15b peuvent en outre être atténuées par des congés de raccordement ou des arrondis.The cavities 15a, 15b can also have a polygonal shape, for example triangular or even square or rectangular, in the main direction X. The edges of the cavities 15a, 15b can also be attenuated by fillets or rounded offs.

Les cavités 15a, 15b présentent par exemple une dimension maximale suivant l'axe transversal 22 qui leur est associé, dite dimension transversale DT, égale au diamètre maximum dmax de l'âme 11 (figure 1). De cette manière, les cavités 15a, 15b forment chacune une rainure s'étendant suivant l'axe transversal 22 qui leur est associé, qui est débouchante à chacune de ses extrémités suivant ledit axe transversal 22. Cela augmente la souplesse de l'âme 11 au niveau des zones de souplesse 13a, 13b.The cavities 15a, 15b have for example a maximum dimension along the transverse axis 22 which is associated with them, called the transverse dimension D T , equal to the maximum diameter d max of the core 11 ( figure 1 ). In this way, the cavities 15a, 15b each form a groove extending along the transverse axis 22 which is associated with them, which opens out at each of its ends along said transverse axis 22. This increases the flexibility of the core 11. at the flexibility zones 13a, 13b.

Les cavités 15a, 15b des zones de souplesse 13a, 13b peuvent être de dimension maximale égale suivant la direction principale X, dimension maximale dite dimension longitudinale DL1. La dimension longitudinale DL1 des cavités 15a, 15b des zones de souplesse 13a, 13b est par exemple comprise entre 1.5 et 15mm. La dimension longitudinale DL1 est de préférence de l'ordre de 1.8mm.The cavities 15a, 15b of the zones of flexibility 13a, 13b can be of equal maximum dimension along the main direction X, the maximum dimension known as the longitudinal dimension D L1 . The longitudinal dimension D L1 of the cavities 15a, 15b of the zones of flexibility 13a, 13b is for example between 1.5 and 15mm. The longitudinal dimension D L1 is preferably of the order of 1.8mm.

En variante, la dimension longitudinale DL1 des cavités 15a, 15b des zones de souplesse 13a, 13b peut varier d'une zone de souplesse à l'autre.As a variant, the longitudinal dimension D L1 of the cavities 15a, 15b of the zones of flexibility 13a, 13b can vary from one zone of flexibility to another.

En outre, les cavités 15a, 15b des zones de souplesse 13a, 13b peuvent présenter la même profondeur suivant l'axe d'amincissement 14a, 14b qui leur est associé. En variante, la profondeur des cavités 15a, 15b des zones de souplesse 13a, 13b peut varier d'une zone de souplesse à l'autre.In addition, the cavities 15a, 15b of the flexibility zones 13a, 13b may have the same depth along the thinning axis 14a, 14b which is theirs. associate. As a variant, the depth of the cavities 15a, 15b of the flexibility zones 13a, 13b can vary from one flexibility zone to another.

L'extrémité libre 20 de l'âme 11 présente par exemple, suivant la direction principale X, une forme comprenant un pan incliné, voire une forme globalement pointue. Cela permet de limiter l'accumulation de produit cosmétique au niveau de ladite extrémité libre 20 et donc d'éviter que le nez de l'utilisateur ne soit souillé lors de la manipulation de l'applicateur 10.The free end 20 of the core 11 has for example, along the main direction X, a shape comprising an inclined face, or even a generally pointed shape. This makes it possible to limit the accumulation of cosmetic product at said free end 20 and therefore to prevent the user's nose from being soiled when handling the applicator 10.

Pour cela, l'extrémité libre 20 de l'âme 11 peut elle-même comprendre une zone de souplesse 13c au niveau de laquelle ladite extrémité libre 20 de l'âme 11 est amincie suivant un axe d'amincissement sensiblement orthogonal à la direction principale X, de sorte à former deux cavités 15c radialement opposées par rapport à ladite direction principale X (figure 3).For this, the free end 20 of the core 11 may itself comprise a zone of flexibility 13c at the level of which said free end 20 of the core 11 is thinned along a thinning axis substantially orthogonal to the main direction. X, so as to form two radially opposed cavities 15c with respect to said main direction X ( figure 3 ).

La zone de souplesse 13c de l'extrémité libre 20 présente un axe d'amincissement décalé angulairement par rapport à l'axe d'amincissement 14a de la zone de souplesse 13a qui lui est adjacente. La zone de souplesse 13c de l'extrémité libre 20 présente de préférence un axe d'amincissement sensiblement orthogonal avec l'axe d'amincissement 14a de la zone de souplesse 13a adjacente.The flexibility zone 13c of the free end 20 has a thinning axis angularly offset with respect to the thinning axis 14a of the flexibility zone 13a which is adjacent to it. The flexibility zone 13c of the free end 20 preferably has a thinning axis that is substantially orthogonal with the thinning axis 14a of the adjacent flexibility zone 13a.

Les deux cavités 15c formées à l'extrémité libre 20 de l'âme 11 présentent par exemple une dimension longitudinale DL2 inférieure à celle des cavités 15a, 15b des autres zones de souplesse 13a, 13b. Ladite dimension longitudinale DL2 sera comprise entre 0.1 et 3mm.The two cavities 15c formed at the free end 20 of the core 11 have, for example, a longitudinal dimension D L2 less than that of the cavities 15a, 15b of the other zones of flexibility 13a, 13b. Said longitudinal dimension D L2 will be between 0.1 and 3mm.

Elle pourra aussi se présenter sous la forme d'une extrémité arrondie, biseautée, droite et/ou chanfreinée, ceci sans sortir du cadre de l'invention.It may also be in the form of a rounded, bevelled, straight and / or chamfered end, this without departing from the scope of the invention.

Les protubérances 12 s'étendent par exemple radialement par rapport à la direction principale X. En d'autres termes, les protubérances 12 font saillie selon une direction sensiblement normale à ladite direction principale X, dite direction radiale.The protuberances 12 extend for example radially with respect to the main direction X. In other words, the protrusions 12 project in a direction substantially normal to said main direction X, called the radial direction.

La pluralité de protubérances 12 est par exemple répartie par rangées 23 s'étendant suivant la direction principale X. Les rangées 23 de protubérances 12 sont particulièrement visibles sur la figure 3. L'applicateur 10 comprend par exemple douze rangées 23 de protubérances 12.The plurality of protrusions 12 is for example distributed by rows 23 extending in the main direction X. The rows 23 of protuberances 12 are particularly visible on the line. figure 3 . The applicator 10 comprises for example twelve rows 23 of protuberances 12.

Un pas ρ entre les protubérances 12 d'une même rangée 23 est par exemple compris entre 0.6 et 1.5mm. Le pas ρ entre les protubérances 12 d'une même rangée est de préférence de l'ordre de 1.25mm. Chaque rangée 23 peut en outre avoir le même pas ρ entre ses protubérances 12 (figure 1).A pitch ρ between the protuberances 12 of the same row 23 is for example between 0.6 and 1.5mm. The pitch ρ between the protuberances 12 of the same row is preferably of the order of 1.25mm. Each row 23 can also have the same pitch ρ between its protuberances 12 ( figure 1 ).

Les rangées 23 de protubérances 12 sont par exemple réparties de manière uniforme autour de la direction principale X. Autrement dit, les protubérances 12 de chaque rangée 23 sont agencées à égale distance angulaire des protubérances 12 des rangées 23 qui leur sont adjacentes.The rows 23 of protuberances 12 are for example distributed uniformly around the main direction X. In other words, the protuberances 12 of each row 23 are arranged at an equal angular distance from the protuberances 12 of the rows 23 which are adjacent to them.

Les protubérances 12 de chaque rangée 23 sont par exemple agencées à une distance angulaire de π 6

Figure imgb0001
rad par rapport aux protubérances 12 des rangées 23 qui lui sont adjacentes.The protrusions 12 of each row 23 are for example arranged at an angular distance of π 6
Figure imgb0001
 rad with respect to the protuberances 12 of the rows 23 which are adjacent to it.

Les protubérances 12 de deux rangées 23 adjacentes sont par exemple décalées les unes par rapport aux autres suivant la direction principale X.The protuberances 12 of two adjacent rows 23 are for example offset with respect to each other in the main direction X.

Les protubérances 12 d'une rangée 23 peuvent en outre être décalées d'une même distance suivant la direction principale X, par rapport aux protubérances 12 des deux rangées 23 qui lui sont adjacentes.The protuberances 12 of a row 23 can also be offset by the same distance in the main direction X, with respect to the protuberances 12 of the two rows 23 which are adjacent thereto.

Les protubérances 12 d'une rangée 23 sur deux sont par exemple décalées d'une même distance suivant la direction principale X, par rapport aux protubérances 12 des rangées 23 qui lui sont adjacentes. Les protubérances d'une rangée 23 sur deux peuvent en outre être décalées, voire en quinconce le long de la direction principale X, par rapport aux protubérances 12 des rangées 23 qui lui sont adjacentes.The protuberances 12 of a row 23 out of two are for example offset by the same distance in the main direction X, with respect to the protuberances 12 of the rows 23 which are adjacent thereto. The protuberances of one row 23 out of two can also be offset, or even staggered, along the main direction X, with respect to the protuberances 12 of the rows 23 which are adjacent to it.

Il est intéressant de noter que les extrémités libres 24 des protubérances 12 définissent ensemble une enveloppe E.It is interesting to note that the free ends 24 of the protuberances 12 together define an envelope E.

L'enveloppe E présente par exemple une forme globalement tronconique.The envelope E has for example a generally frustoconical shape.

De préférence, la petite section du tronc de cône formé par l'enveloppe E est agencée en regard de l'extrémité libre 20 de l'âme 11, tandis que la grande section du tronc de cône formé par l'enveloppe E est agencée à l'opposé de l'extrémité libre 20 de l'âme 11.Preferably, the small section of the truncated cone formed by the casing E is arranged opposite the free end 20 of the core 11, while the large section of the truncated cone formed by the casing E is arranged at the opposite of the free end 20 of the core 11.

L'enveloppe présente par exemple un diamètre maximum compris entre 4 et 10mm, de préférence compris entre 5 et 8mm.The envelope has for example a maximum diameter of between 4 and 10mm, preferably between 5 and 8mm.

La longueur L des protubérances 12, définie entre la direction principale X et l'extrémité libre 24 des protubérances 12, varie d'une rangée 23 de protubérances 12 à une autre. On entend par « longueur L des protubérances 12 », l'extension radiale des protubérances entre l'axe X de l'âme 11 et l'extrémité libre la protubérance » (voir fig. 1). La longueur L est par exemple comprise entre 2.0 et 5.0mm et plus particulièrement entre 2.5 et 4.0mm.The length L of the protrusions 12, defined between the main direction X and the free end 24 of the protuberances 12, varies from one row 23 of protuberances 12 to another. The term “length L of the protuberances 12” is understood to mean the radial extension of the protuberances between the X axis of the core 11 and the free end of the protuberance ”(see fig. 1 ). The length L is for example between 2.0 and 5.0mm and more particularly between 2.5 and 4.0mm.

La longueur L des protubérances 12 d'une rangée 23 sur deux sont, en moyenne, inférieure à la longueur L des protubérances 12 des rangées 23 qui lui sont adjacentes.The length L of the protuberances 12 of a row 23 out of two are, on average, less than the length L of the protrusions 12 of the rows 23 which are adjacent to it.

La longueur L des protubérances 12 peut également varier au sein d'une même rangée 23 de protubérances 12.The length L of the protuberances 12 can also vary within the same row 23 of protuberances 12.

La longueur L des protubérances 12 d'une même rangée 23 augmente par exemple à mesure que l'on s'éloigne de l'extrémité libre 20 de l'âme 11.The length L of the protuberances 12 of the same row 23 increases for example as one moves away from the free end 20 of the core 11.

Les protubérances 12 sont par exemple globalement tronconiques. On entend par «globalement tronconique » le fait que la section des protubérances 12 augmente ou diminue progressivement depuis la base vers l'extrémité libre 24 desdites protubérances 12. De préférence, la base des protubérances 12 est de plus grande section que l'extrémité libre 24 desdites protubérances 12.The protuberances 12 are for example generally frustoconical. By “generally frustoconical” is meant the fact that the section of the protuberances 12 increases or decreases progressively from the base towards the free end 24 of said protuberances 12. Preferably, the base of the protuberances 12 has a larger section than the free end. 24 of said protrusions 12.

Les protubérances 12 présentent en outre chacune une section de forme en demi-ellipse - par exemple en demi-ovale - formant une surface plane 25, et sont positionnées de sorte que les surfaces planes 25 des protubérances 12 soient orientées dans le même sens giratoire.The protrusions 12 further each have a half-elliptical - for example half-oval - shaped section forming a flat surface 25, and are positioned so that the flat surfaces 25 of the protrusions 12 are oriented in the same gyratory direction.

L'âme 11 peut comprendre des protubérances 12 faisant saillie depuis les zones de souplesse 13a, 13b de l'âme 11.The core 11 may include protuberances 12 projecting from the zones of flexibility 13a, 13b of the core 11.

Aucune protubérance 12 peut en variante s'étendre depuis une, plusieurs ou toutes les zones de souplesse 13a, 13b de l'âme 11.No protuberance 12 can alternatively extend from one, more or all of the zones of flexibility 13a, 13b of the core 11.

Les protubérances 12 sont par exemple issues de matière de l'âme 11.The protuberances 12 are for example made from material of the core 11.

L'âme 11 peut être une âme moulée, notamment en matière plastique. L'âme 11 et les protubérances 12 sont par exemple moulées ensemble. Les protubérances 12 peuvent en variante être surmoulées sur l'âme 12. L'âme 11 et les protubérances 12 peuvent être moulées en un matériau à base de LDPE (ou « polyéthylène basse densité »). D'autres matériaux peuvent être utilisés, à savoir la matière « EXACT » commercialisée par la société ExxonMobil ou la matière « HYTREL » commercialisée par la société Dupont de Nemours, voire un mélange de ces matières.The core 11 can be a molded core, in particular made of plastic. The core 11 and the protuberances 12 are for example molded together. The protuberances 12 may alternatively be overmolded on the core 12. The core 11 and the protuberances 12 may be molded from a material based on LDPE (or “low density polyethylene”). Other materials can be used, namely the “EXACT” material sold by the company ExxonMobil or the “HYTREL” material sold by the company Dupont de Nemours, or even a mixture of these materials.

Le diamètre maximum dmax de l'âme 11 est par exemple compris entre 2 et 6mm.The maximum diameter d max of the core 11 is for example between 2 and 6mm.

On comprendra que les zones de souplesse 13a, 13b présentent un avantage particulier, lorsque l'âme 11 a un grand diamètre maximum dmax, notamment un diamètre maximum dmax compris entre 4 et 6mm. De telles âmes 11 seront nommées dans la suite de la description « âmes à grand diamètre ».It will be understood that the zones of flexibility 13a, 13b have a particular advantage, when the core 11 has a large maximum diameter d max , in particular a maximum diameter d max of between 4 and 6mm. Such cores 11 will be referred to in the remainder of the description as “large diameter cores”.

Les âmes 11 à grand diamètre sont intéressantes car les protubérances 12 qui en font saillie sont globalement plus courtes, pour un même diamètre d'enveloppe E qu'une âme 11 de plus petit diamètre maximum dmax, de sorte qu'avec les âmes 11 à grand diamètre, il est possible d'attaquer les cils de l'utilisateur dès la racine et donc de les charger davantage en produit cosmétique, lors de l'application du produit cosmétique. Les âmes 11 à grand diamètre permettent ainsi de donner du volume aux cils de l'utilisateur.The large diameter webs 11 are interesting because the protuberances 12 which protrude from them are generally shorter, for the same envelope diameter E than a web 11 of smaller maximum diameter d max , so that with webs 11 with a large diameter, it is possible to attack the user's eyelashes from the root and therefore to load them more with cosmetic product, during the application of the cosmetic product. The large-diameter cores 11 thus make it possible to give volume to the user's eyelashes.

Les âmes 11 à grand diamètre sont aussi intéressantes car elles peuvent accueillir un plus grand nombre de rangées de protubérances 12 autour de la direction principale X, et ainsi améliorer le peignage et donc la séparation des cils de l'utilisateur, lors de l'application du produit cosmétique.The large-diameter cores 11 are also interesting because they can accommodate a greater number of rows of protuberances 12 around the main direction X, and thus improve the combing and therefore the separation of the user's eyelashes, during the application. cosmetic product.

Les âmes 11 à grand diamètre ont cependant tendance à être plus rigides du fait de leur grand diamètre maximum dmax, de sorte que les zones de souplesse 13a, 13b permettent de contrebalancer cette tendance en leur conférant plus de souplesse et en augmentant ainsi la précision avec laquelle le produit cosmétique est appliqué sur les cils de l'utilisateur.The large diameter cores 11 however tend to be more rigid due to their large maximum diameter d max , so that the flexibility zones 13a, 13b make it possible to counteract this tendency by giving them more flexibility and thus increasing the precision. with which the cosmetic product is applied to the eyelashes of the user.

Le cas échéant, les protubérances 12 faisant saillie depuis les zones de souplesse 13a, 13b des âmes 11 à grand diamètre sont en outre plus longues et donc plus souples, sans que le diamètre maximum de l'enveloppe E ne soit augmenté, de sorte que lesdites protubérances 12 permettent, en complémentarité avec les zones de souplesse 13a, 13b, d'améliorer le peignage de cils de l'utilisateur et donc la séparation et l'allongement desdits cils, lors de l'application du produit cosmétique.Where appropriate, the protuberances 12 projecting from the zones of flexibility 13a, 13b of the cores 11 with a large diameter are also longer and therefore more flexible, without the maximum diameter of the envelope E being increased, so that said protuberances 12 make it possible, in complementarity with the zones of flexibility 13a, 13b, to improve the combing of the user's eyelashes and therefore the separation and lengthening of said eyelashes, during the application of the cosmetic product.

Il est à noter, aussi, que l'applicateur 10 forme avantageusement une brosse.It should also be noted that the applicator 10 advantageously forms a brush.

Il est à noter, encore, que l'invention concerne aussi un ensemble applicateur pour produit cosmétique, comprenant un récipient comprenant un corps formant un réservoir R destiné à contenir le produit cosmétique, et un applicateur 10 tel que décrit ci-dessus configuré pour se déplacer par rapport au récipient entre une position de fermeture de l'ensemble dans laquelle l'applicateur 10 est fixé sur le récipient et l'applicateur 10 est logé à l'intérieur du réservoir, et une position d'ouverture de l'ensemble dans laquelle l'applicateur 10 libère le récipient et l'applicateur est disposé à l'extérieur du réservoir (voir figure 6).It should be noted, again, that the invention also relates to an applicator assembly for a cosmetic product, comprising a container comprising a body forming a reservoir R intended to contain the cosmetic product, and an applicator 10 as described above configured to stand. move relative to the container between a closed position of the assembly in which the applicator 10 is attached to the container and the applicator 10 is housed inside the reservoir, and an open position of the assembly in which the applicator 10 releases the container and the applicator is placed outside the reservoir (see figure 6 ).

Il est à noter également que des variantes de réalisation sont bien sûr possibles. Notamment il est aussi envisageable, dans des exemples de réalisation supplémentaires, non illustrés ici, que :

  • l'âme 11 comprend en outre des troisièmes zones de souplesse dont les axes d'amincissement sont parallèles entre eux et décalés angulairement par rapport aux axes d'amincissement 14a, 14b des premières et deuxièmes zones de souplesse 13a, 13b ;
  • l'âme 11 comprend une alternance de premières zones de souplesse 13a, de deuxième zones de souplesse 13b et de troisièmes zones de souplesse ;
  • une zone de souplesse sur trois, suivant la direction principale X, est une première zone de souplesse 13a, une zone de souplesse sur trois, suivant la direction principale X, est une deuxième zone de souplesse 13b et une zone de souplesse sur trois, suivant la direction principale X, est une troisième zone de souplesse.
  • les axes d'amincissement 14a, 14b des premières, deuxièmes et troisièmes zones de souplesse 13a, 13b forment respectivement entre eux un angle de décalage α de l'ordre de 60°.
It should also be noted that variant embodiments are of course possible. In particular, it is also conceivable, in additional exemplary embodiments, not illustrated here, that:
  • the core 11 further comprises third zones of flexibility, the thinning axes of which are mutually parallel and angularly offset with respect to the thinning axes 14a, 14b of the first and second zones of flexibility 13a, 13b;
  • the core 11 comprises an alternation of first zones of flexibility 13a, of second zones of flexibility 13b and of third zones of flexibility;
  • one out of three zones of flexibility, along the main direction X, is a first zone of flexibility 13a, one of three zones of flexibility, along the main direction X, is a second zone of flexibility 13b and one of three zones of flexibility, according to the main direction X is a third flexibility zone.
  • the thinning axes 14a, 14b of the first, second and third flexibility zones 13a, 13b respectively form an offset angle α of the order of 60 ° between them.
