Description

L'invention concerne un article de produit cosmétique notamment pour les lèvres.The invention relates to an article of cosmetic product, in particular for the lips.

Un rouge à lèvres comprend classiquement un tube ainsi qu'une réserve de produit cosmétique qui peut notamment être sous forme solide ou pâteuse, appelée « raisin ». Le produit est déplacé à une extrémité du tube par un mécanisme afin que l'utilisatrice puisse l'appliquer sur ses lèvres. La formulation du produit est choisie afin d'obtenir le meilleur résultat de maquillage possible tout en assurant une bonne résistance du raisin notamment mécanique et thermique. Pour cela, il est possible de moduler les proportions des quatre composants principaux du raisin, à savoir des cires, des huiles, des beurres et des pigments. Afin d'obtenir de bons résultats de maquillage, il est souhaitable de diminuer la solidité du raisin, procurée en grande partie par les cires en tant qu'éléments structurants, par exemple en augmentant la proportion des huiles et des beurres. Cependant, cette augmentation a pour conséquence une baisse de la résistance mécanique du raisin et favorise donc sa casse. En outre, cette augmentation favorise à terme des phénomènes d'exsudation qui, en plus de dénaturer la formulation initiale du raisin, ont un impact visuel négatif sur le consommateur. On rappelle à ce sujet qu'une utilisatrice est susceptible de conserver un rouge à lèvre pendant plusieurs années.A lipstick conventionally comprises a tube as well as a reserve of cosmetic product which can in particular be in solid or pasty form, called “grape”. The product is moved to one end of the tube by a mechanism so that the user can apply it to her lips. The formulation of the product is chosen in order to obtain the best possible makeup result while ensuring good resistance of the grape, particularly mechanical and thermal. For this, it is possible to modulate the proportions of the four main components of the grape, namely waxes, oils, butters and pigments. In order to obtain good makeup results, it is desirable to reduce the strength of the grape, provided in large part by the waxes as structuring elements, for example by increasing the proportion of oils and butters. However, this increase results in a decrease in the mechanical resistance of the grape and therefore promotes its breakage. In addition, this increase ultimately promotes exudation phenomena which, in addition to denaturing the initial formulation of the grape, have a negative visual impact on the consumer. It is recalled in this regard that a user is likely to keep a lipstick for several years.

Le document EP 1 154 710 A1 divulgue un article de cosmétique selon le préambule de la revendication 1.The document EP 1 154 710 A1 discloses a cosmetic article according to the preamble of claim 1.

Un but de l'invention est donc d'améliorer les articles de cosmétique.An aim of the invention is therefore to improve cosmetic articles.

A cet effet, on prévoit selon l'invention un article de cosmétique selon la revendication 1.For this purpose, according to the invention, a cosmetic article according to claim 1 is provided.

Dans le cas d'un bloc solide de produit cosmétique, le passage à travers les grilles permet de rendre le produit pâteux et donc d'améliorer l'effet de maquillage obtenu et de simplifier l'application du maquillage pour l'utilisatrice. Dans le cas d'un produit cosmétique sous forme pâteuse, ce passage permet de fluidifier le produit afin, encore une fois, d'obtenir un meilleur résultat de maquillage et de simplifier l'application du maquillage par l'utilisatrice.In the case of a solid block of cosmetic product, the passage through the grids makes it possible to make the product pasty and therefore to improve the makeup effect obtained and to simplify the application of makeup for the user. In the case of a cosmetic product in pasty form, this passage makes it possible to thin the product in order, once again, to obtain a better makeup result and to simplify the application of makeup by the user.

De plus, la grille amont engendre une première déstructuration du produit au passage des orifices. La grille aval poursuit ensuite ce travail sur la même fraction de produit. Comme ce travail de ramollissement et d'attendrissement du raisin a lieu en deux étapes, les efforts à produire sur le mécanisme par l'utilisatrice pour l'obtenir peuvent demeurer modérés, par comparaison avec la présence d'une grille unique.In addition, the upstream grid generates a first destructuring of the product as it passes through the orifices. The downstream grid then continues this work on the same fraction of product. As this work of softening and tenderizing the grapes takes place in two stages, the efforts to be produced on the mechanism by the user to obtain it can remain moderate, compared with the presence of a single grid.

De préférence, une plus grande dimension d'un orifice de la grille amont est plus grande qu'une plus grande dimension d'un orifice de la grille aval, le rapport entre ces deux dimensions étant de préférence supérieur à 1 et inférieur ou égal à 100.Preferably, a larger dimension of an orifice in the upstream grid is greater than a larger dimension of an orifice in the downstream grid, the ratio between these two dimensions preferably being greater than 1 and less than or equal to 100.

Ainsi, dans le cas d'un bloc solide de produit, on obtient une déstructuration progressive du bloc qui nécessite encore moins d'effort de la part de l'utilisatrice que s'il n'y avait qu'une grille ou que si les deux grilles avaient les mêmes dimensions. Cela s'applique également dans le cas où le produit est sous forme pâteuse, cet agencement particulier permettant d'obtenir une pâte plus fluide avec un effort réduit.Thus, in the case of a solid block of product, a progressive destructuring of the block is obtained which requires even less effort on the part of the user than if there was only one grid or if the two grids had the same dimensions. This also applies in the case where the product is in pasty form, this particular arrangement making it possible to obtain a more fluid paste with reduced effort.

Au moins une des grilles est tissée et, le tissage étant formé par des fils de chaîne et des fils de trame, les fils de chaîne ont un diamètre différent de celui des fils de trame.At least one of the grids is woven and, the weaving being formed by warp threads and weft threads, the warp threads have a different diameter from that of the weft threads.

Cette disposition particulière permet notamment d'orienter le produit passant au travers de la grille dans une direction souhaitée afin d'obtenir, par exemple, un résultat de maquillage particulier. Cela permet également, dans le cas d'un bloc solide de produit, de déstructurer différemment le bloc selon une direction particulière. Autrement dit, la déstructuration a lieu de façon anisotrope. On peut prévoir que les fils de chaîne ont un diamètre plus important que les fils de trame ou l'inverse. On peut également prévoir que, au sein d'une même grille, les différents fils de chaîne ont des diamètres différents. De même, on peut prévoir que sur une même grille, les différents fils de trame ont des diamètres différents.This particular arrangement makes it possible in particular to orient the product passing through the grid in a desired direction in order to obtain, for example, a particular makeup result. This also makes it possible, in the case of a solid block of product, to destructure the block differently in a particular direction. In other words, the destructuring takes place anisotropically. Provision can be made for the warp threads to have a larger diameter than the weft threads or vice versa. It is also possible to provide that, within the same grid, the different warp threads have different diameters. Likewise, provision can be made for the different weft threads to have different diameters on the same grid.

De préférence, au moins une des grilles est d'une seule pièce.Preferably, at least one of the grids is in one piece.

Cela permet notamment de donner aux contours des ouvertures des formes difficiles à obtenir autrement, par exemple par tissage. On peut envisager la fabrication des grilles par injection ou encore par synthèse additive.This makes it possible in particular to give the outlines of the openings shapes that are difficult to obtain otherwise, for example by weaving. It is possible to envisage manufacturing the grids by injection or else by additive synthesis.

De manière préférée, tous les orifices d'au moins une des grilles ont des contours superposables.Preferably, all the orifices of at least one of the grids have superimposable contours.

Ainsi, on aura une répartition homogène de la pâte de produit sur la grille en sortie des orifices qui permet une application homogène du produit notamment dans le cas où les toutes les grilles présentent cette caractéristiques. On peut également prévoir que toutes les grilles d'un article ont cette caractéristique.Thus, there will be a homogeneous distribution of the product paste on the grid at the outlet of the orifices which allows a homogeneous application of the product, in particular in the case where all the grids have these characteristics. Provision can also be made for all the grids of an article to have this characteristic.

Avantageusement, au moins une des grilles présente des orifices ayant des contours non superposables.Advantageously, at least one of the grids has orifices having non-superimposable contours.

Cette disposition particulière permet notamment d'orienter la pâte de produit dans une direction souhaitée lors de son passage à travers la grille. On peut aussi, par exemple, concentrer davantage la pâte à un endroit particulier de la surface de la grille de sorte que l'application du produit soit plus précise. Dans le cas où deux grilles identiques de ce type sont utilisées, le phénomène d'orientation du produit suivant une direction particulière est encore plus marqué. On peut bien entendu prévoir un nombre de grilles, identiques ou non, plus important.This particular arrangement makes it possible in particular to orient the product paste in a desired direction as it passes through the grid. It is also possible, for example, to further concentrate the paste at a particular location on the surface of the grid so that the application of the product is more precise. In the case where two identical grids of this type are used, the phenomenon of orientation of the product in a particular direction is even more marked. It is of course possible to provide a greater number of grids, identical or not, greater.

De préférence, les contours des orifices ont l'une des formes suivantes : rectangulaire, pentagonale, hexagonale, octogonale, ronde, ovale ou oblongue.Preferably, the outlines of the orifices have one of the following shapes: rectangular, pentagonal, hexagonal, octagonal, round, oval or oblong.

Certaines de ces différentes formes des orifices participent également à l'orientation du produit lors de son passage à travers la grille.Some of these different shapes of the orifices also participate in the orientation of the product as it passes through the grid.

Préférentiellement, une plus grande dimension des orifices d'au moins une des grilles est comprise entre 50 et 450 µm.Preferably, a larger dimension of the orifices of at least one of the grids is between 50 and 450 μm.

De préférence encore, au moins une des grilles est agencée de sorte qu'une distance minimale entre les orifices est comprise entre 100 à 300 µm.More preferably, at least one of the grids is arranged so that a minimum distance between the orifices is between 100 to 300 μm.

Cette disposition participe à obtenir de bons résultats de déstructuration du bloc, dans le cas où le produit est solide, sans que l'utilisatrice ait besoin de fournir un effort trop important. Dans le cas où le produit est pâteux, cette disposition permet d'obtenir de bons résultats de fluidification du produit. On peut prévoir que la distance minimale entre les différents orifices contigus de la grille n'est pas constante entre les différents orifices. On peut en outre prévoir que la répartition des distances minimales entre les orifices contigus de la grille permet de diriger le produit qui passe à travers la grille dans une direction souhaitée.This arrangement helps to obtain good results in the destructuring of the block, in the case where the product is solid, without the user having to provide too much effort. In the case where the product is pasty, this arrangement makes it possible to obtain good results in the fluidization of the product. Provision can be made for the minimum distance between the various contiguous orifices of the grid to be not constant between the various orifices. Provision can also be made for the distribution of the minimum distances between the contiguous orifices of the grid to direct the product which passes through the grid in a desired direction.

Avantageusement, l'article comprend en outre au moins une grille intermédiaire entre les deux grilles, une plus grande dimension des orifices respectifs des grilles diminuant de l'amont vers l'aval par référence à une direction de passage du produit à travers les grilles lors d'une sortie du produit hors de l'article.Advantageously, the article further comprises at least one intermediate grid between the two grids, a larger dimension of the respective openings of the grids decreasing from upstream to downstream with reference to a direction of passage of the product through the grids during an exit of the product from the article.

Cette caractéristique permet de réduire encore l'effort nécessaire pour déstructurer un bloc de produit ou pour obtenir une pâte plus fluide.This characteristic makes it possible to further reduce the effort required to break down a block of product or to obtain a more fluid dough.

De préférence, le produit cosmétique forme un bloc solide.Preferably, the cosmetic product forms a solid block.

Nous allons décrire en référence aux figures 1 à 9 un article de cosmétique pour les lèvres. Nous traiterons ci-dessous du cas dans lequel cet article est un rouge à lèvres. Bien entendu, le produit cosmétique pour les lèvres peut être différent et on ne se limite pas non plus ici aux rouges à lèvres de couleur rouge, la couleur du produit cosmétique pouvant être rose, noire, marron, etc.We will describe with reference to figures 1 to 9 an article of cosmetic for the lips. We will deal with the case in which this item is lipstick below. Of course, the cosmetic product for the lips can be different and we are not limited here either to red lipsticks, the color of the cosmetic product being able to be pink, black, brown, etc.

Le dispositifThe device

L'enveloppe extérieure de l'article 1 de cosmétique représenté à la figure 1 est formée par un corps 2 ainsi qu'un capuchon (non représenté). Le corps présente une butée, formée par un épaulement, contre laquelle le capuchon est apte à venir en appui de sorte que le corps s'emboite en partie dans le capuchon.The outer casing of cosmetic item 1 shown in figure 1 is formed by a body 2 and a cap (not shown). The body has an abutment, formed by a shoulder, against which the cap is able to bear so that the body fits in part into the cap.

Le corps comprend deux portions cylindriques, par exemple à section sensiblement carrée dans un plan transversal au corps de l'applicateur, la seconde section ayant une dimension réduite par rapport à la première section. Ces deux sections sont séparées par la butée. Le corps est creux et ouvert au niveau de ses extrémités distale et proximale. L'ouverture 11 de l'extrémité proximale du corps est partiellement obturée par une partie de fond 3 du corps qui s'étend, à partir de cette extrémité, dans un plan transversal au corps de l'applicateur.The body comprises two cylindrical portions, for example with a substantially square section in a plane transverse to the body of the applicator, the second section having a reduced dimension compared to the first section. These two sections are separated by the stopper. The body is hollow and open at its distal and proximal ends. The opening 11 of the proximal end of the body is partially closed by a bottom part 3 of the body which extends, from this end, in a plane transverse to the body of the applicator.

Une cavité formée par le corps 2 comprend, de l'extérieur vers l'intérieur, en direction d'un axe 13 du corps, un élément tubulaire 4 présentant une rampe en hélice, un tube 5 et un piston 6 dont les axes longitudinaux principaux 13 sont confondus.A cavity formed by the body 2 comprises, from the outside towards the inside, in the direction of an axis 13 of the body, a tubular element 4 having a helical ramp, a tube 5 and a piston 6 whose main longitudinal axes 13 are confused.

L'élément tubulaire 4 (voir figure 8) est de forme générale cylindrique creuse à section circulaire dans un plan perpendiculaire à l'axe longitudinal 13 et est ouvert au niveau de ses deux extrémités. Il présente une face externe sensiblement lisse et une face interne présentant un sillon formant une rampe hélicoïdale 7 s'étendant sur une plus grande partie de la longueur de l'élément tubulaire 4. Sur la figure 8, on distingue huit tours d'hélice. Bien entendu, on pourra prévoir un nombre différent de tours d'hélice, plus grand ou plus faible, en fonction de l'effet souhaité. Cet élément repose par son extrémité proximale sur la partie de fond 3. L'extrémité distale de cet élément 4 s'étend elle sensiblement au niveau de la butée. Cet élément est rigidement fixé au corps 2 de l'article.The tubular element 4 (see figure 8 ) is of generally hollow cylindrical shape with a circular section in a plane perpendicular to the longitudinal axis 13 and is open at its two ends. It has a substantially smooth outer face and an inner face having a groove forming a helical ramp 7 extending over a greater part of the length of the tubular element 4. On the figure 8 , there are eight turns of the propeller. Of course, it is possible to provide a different number of helix turns, greater or less, depending on the desired effect. This element rests by its proximal end on the bottom part 3. The distal end of this element 4 itself extends substantially at the level of the stop. This element is rigidly fixed to the body 2 of the article.

Le tube 5 (voir figure 7) forme un cylindre creux à section circulaire dans un plan perpendiculaire à l'axe 13 et est ouvert au niveau de ses deux extrémités. L'extrémité distale du tube 5 est biseautée. On peut bien entendu prévoir que cette extrémité ne soit pas biseautée. Le tube 5 présente deux échancrures formant deux rampes 8 qui s'étendent depuis l'extrémité proximale du tube jusqu'à une portion médiane du tube. Les rampes sont de forme générale rectiligne allongée parallèles à l'axe 13. Elles sont diamétralement opposées l'une à l'autre de part et d'autre de cet axe.Tube 5 (see figure 7 ) forms a hollow cylinder with a circular section in a plane perpendicular to the axis 13 and is open at its two ends. The distal end of tube 5 is bevelled. It is of course possible to provide that this end is not bevelled. The tube 5 has two notches forming two ramps 8 which extend from the proximal end of the tube to a middle portion of the tube. The ramps are generally rectilinear elongated parallel to the axis 13. They are diametrically opposed to each other on either side of this axis.

Le piston 6 (voir figure 6) forme un cylindre creux à section circulaire dans un plan perpendiculaire à l'axe 13. L'extrémité proximale du piston est ouverte et son extrémité distale en biseau et est fermée par une portion 9 qui est légèrement en retrait par rapport à l'extrémité distale du piston de façon à former une cuvette dans laquelle est engagée la base du raisin. Ceci améliore la liaison entre le raisin et le piston. Sur la figure 1, la portion 9 du piston qui ferme l'extrémité distale est plane et inclinée par rapport à l'axe 13 de sorte qu'elle est aussi biseautée. Le piston présente, au niveau de la face externe de sa portion proximale, deux plots 10 de guidage diamétralement opposés qui s'étendent en saillie de la face externe du piston. Bien entendu, on peut prévoir que les plots soient disposés à d'autres endroits de la face externe du piston. Ces plots sont aptes à parcourir chacun à la fois la rampe rectiligne 8 du tube 5 et la rampe hélicoïdale 7 de l'élément tubulaire 4. Le piston présente en outre au niveau de son extrémité distale un bourrelet d'étanchéité 12 s'étendant sur tout le pourtour de l'extrémité distale du piston.Piston 6 (see figure 6 ) forms a hollow cylinder with a circular section in a plane perpendicular to the axis 13. The proximal end of the piston is open and its distal end bevelled and is closed by a portion 9 which is slightly set back from the end distal of the piston so as to form a bowl in which the base of the grape is engaged. This improves the connection between the grape and the piston. On the figure 1 , the portion 9 of the piston which closes the distal end is flat and inclined with respect to the axis 13 so that it is also bevelled. The piston has, at the level of the external face of its proximal portion, two diametrically opposed guide pins 10 which project from the external face of the piston. Of course, provision can be made for the studs to be arranged at other locations on the outer face of the piston. These studs are each capable of traversing both the rectilinear ramp 8 of the tube 5 and the helical ramp 7 of the tubular element 4. The piston also has at its distal end a sealing bead 12 extending over all around the distal end of the plunger.

La portion proximale du tube 5 est donc logée à l'intérieur du corps et de l'élément tubulaire 4 et sa partie distale s'étend en dehors, en saillie du corps 2 de l'article 1. Le tube est monté mobile à rotation autour de l'axe 13 par rapport à l'ensemble formé par le corps 2 et l'élément tubulaire 4, par des moyens de guidage adaptés. Le piston 6 est lui logé mobile à translation dans le tube 5 grâce à ses plots 10 aptes à parcourir les différentes rampes 7, 8.The proximal portion of the tube 5 is therefore housed inside the body and the tubular element 4 and its distal part extends outside, projecting from the body 2 of the article 1. The tube is mounted so as to be able to rotate. around the axis 13 relative to the assembly formed by the body 2 and the tubular element 4, by suitable guide means. The piston 6 is housed movable in translation in the tube 5 by virtue of its studs 10 capable of traversing the various ramps 7, 8.

L'article 1 comprend en outre un bloc solide 14 de rouge à lèvres ou raisin. Ce raisin 14 a une forme générale cylindrique pleine à section circulaire dans un plan perpendiculaire à l'axe 13. L'extrémité distale du raisin 14 a une forme biseautée. Bien entendu, on peut prévoir d'autres formes de cette extrémité, ces formes étant largement connues de l'homme du métier. Le raisin 14 repose par sa partie proximale sur l'extrémité distale 9 du piston 6. Le piston est donc apte à entrainer en coulissement le raisin 14 le long de l'axe 13 à l'intérieur du tube 5.The article 1 further comprises a solid block 14 of lipstick or grape. This grape 14 has a generally solid cylindrical shape with a circular section in a plane perpendicular to the axis 13. The distal end of the grape 14 has a bevelled shape. Of course, other shapes can be provided for this end, these shapes being widely known to those skilled in the art. The grape 14 rests by its proximal part on the distal end 9 of the piston 6. The piston is therefore able to cause the grape 14 to slide along the axis 13 inside the tube 5.

Ce raisin a un indice de rupture mesuré à 20°C compris entre 0,2 et 20 N (soit environ entre 20 et 2000 grammes-force). L'indice de rupture traduit la résistance mécanique du bloc.This grape has a rupture index measured at 20 ° C of between 0.2 and 20 N (approximately between 20 and 2000 gram-force). The fracture index reflects the mechanical resistance of the block.

Cette mesure est par exemple obtenue avec un banc d'essai de référence TCM 201 M, et un capteur de force 23 (dynamomètre) de référence DFS 5 Kilogramme-Force (KgF) (soit environ 49 N) commercialisés par Chatillon avec une vitesse de descente de tige de 132 mm/min. L'indice de rupture d'un raisin représente la force moyenne qu'il faut appliquer pour casser le raisin.This measurement is for example obtained with a reference test bench TCM 201 M, and a force sensor 23 (dynamometer) of reference DFS 5 Kilogram-Force (KgF) (i.e. approximately 49 N) marketed by Chatillon with a speed of 132 mm / min rod descent. The breaking index of a grape represents the average force that must be applied to break the grape.

Pour la mesure, la température du produit est contrôlée puisqu'elle a un impact direct sur les résultats. Le raisin pourra être porté à la température souhaitée avant la mesure selon des méthodes connues. On peut par exemple laisser le raisin dans une enceinte thermostatée à 20°C ou bien dans une pièce régulée à 20°C. La température du produit est mesurée à l'aide d'un thermomètre inséré au cœur du raisin avant la mesure afin de s'assurer qu'elle soit comprise entre 19,5°C et 21,5°C.For the measurement, the temperature of the product is controlled since it has a direct impact on the results. The grape can be brought to the desired temperature before measurement according to known methods. For example, the grapes can be left in an enclosure thermostatically controlled at 20 ° C or else in a room regulated at 20 ° C. The temperature of the product is measured using a thermometer inserted in the heart of the grape before measurement to ensure that it is between 19.5 ° C and 21.5 ° C.

De manière général, on peut utiliser des capteurs de force de 1 ou 5 KgF, les capteurs de force de 1 KgF permettant des mesures jusqu'à une valeur maximale mesurée de 1000 gF (soit environ 9,8 N), au-delà le capteur 5 KgF doit être utilisé.In general, force sensors of 1 or 5 KgF can be used, force sensors of 1 KgF allowing measurements up to a maximum measured value of 1000 gF (i.e. approximately 9.8 N), beyond the 5 KgF sensor must be used.

En référence à la figure 9, la mesure est effectuée avec un tube 24 de même diamètre que le tube 5. Ce tube 24 est placé à l'horizontal avec le raisin 14 dans son état d'origine dans sa position la plus sortie de l'article possible. Le tube est maintenu immobile avec une bague de calage 20 et une vis de fixation 21, la face biseautée du raisin étant orientée vers le bas (voir figure 9). La tige 22, qui comprend une butée en forme de « V » renversé, descend verticalement à la vitesse programmée, soit 132 mm/min dans le cas présent, entre en contact avec le raisin 14 et le casse. Le dynamomètre 23 donne une valeur qui correspond à la force de compression maximale mesurée pendant la rupture du raisin, c'est-à-dire l'indice de rupture. Plusieurs essais peuvent être réalisés pour une même formulation de raisin afin de pouvoir calculer une moyenne et un écart-type de l'indice de rupture.With reference to the figure 9 , the measurement is carried out with a tube 24 of the same diameter as the tube 5. This tube 24 is placed horizontally with the grape 14 in its original state in its position as far out of the article as possible. The tube is held stationary with a setting ring 20 and a fixing screw 21, the bevelled face of the grape facing downwards (see figure 9 ). The rod 22, which comprises a stop in the shape of an inverted "V", descends vertically at the programmed speed, ie 132 mm / min in this case, comes into contact with the grape 14 and breaks it. The dynamometer 23 gives a value which corresponds to the maximum compressive force measured during the breaking of the grape, that is to say the breaking index. Several tests can be carried out for the same grape formulation in order to be able to calculate an average and a standard deviation of the breaking index.

L'article 1 comprend en outre deux grilles 15 de forme générale plane circulaire. Dans le mode de réalisation présenté, les grilles sont des grilles tissées, par exemple en métal, comprenant des fils de chaîne 18 et des fils de trame 19, ces fils formant des orifices 16 de forme générale rectangulaire. Le fait que les grilles soient en métal est particulièrement avantageux, notamment pour la grille la plus distale, puisque cela procure lors de l'application du produit sur les lèvres un effet « rafraichissant » plaisant pour l'utilisatrice. Une plus grande dimension d, ici une diagonale, des orifices 16 est comprise entre 50 et 450 µm. Les fils de trame et de chaîne ont un diamètre a, b compris entre 100 et 300 µm qui correspond donc également aux valeurs de distances minimales entre les orifices. Les grilles 15 sont rigidement fixées à l'extrémité distale du tube 5 via un support 17. Dans le présent exemple, les orifices de la grille aval sont comme suit :

  • plus grande dimension : 280 µm,
  • largeur : 100 µm,
  • longueur : 261 µm,
  • diamètre des fils de chaine a : 150 µm,
  • diamètre des fils de trame b : 100 µm,
  • distance entre les orifices : 100 µm.
The article 1 further comprises two grids 15 of generally circular planar shape. In the embodiment shown, the grids are woven grids, for example made of metal, comprising warp threads 18 and weft threads 19, these threads forming orifices 16 of generally rectangular shape. The fact that the grids are made of metal is particularly advantageous, in particular for the most distal grid, since this provides, during the application of the product to the lips, a “refreshing” effect which is pleasant for the user. Greater dimension, here a diagonal orifices 16 is between 50 and 450 .mu.m. The weft and warp threads have a diameter a, b of between 100 and 300 μm which therefore also corresponds to the minimum distance values between the orifices. The grids 15 are rigidly fixed to the distal end of the tube 5 via a support 17. In the present example, the holes of the downstream grid are as follows:
  • largest dimension: 280 µm,
  • width: 100 µm,
  • length: 261 µm,
  • diameter of the chain wires a : 150 µm,
  • diameter of the weft threads b : 100 µm,
  • distance between orifices: 100 µm.

Les orifices de la grille amont sont comme suit :

  • plus grande dimension : 400 µm,
  • largeur : 300 µm,
  • longueur : 264,5 µm,
  • diamètre des fils de chaine a : 150 µm,
  • diamètre des fils de trame b : 100 µm,
  • distance entre les orifices : 100 µm.
The upstream grille openings are as follows:
  • largest dimension: 400 µm,
  • width: 300 µm,
  • length: 264.5 µm,
  • diameter of the chain wires a : 150 µm,
  • diameter of the weft threads b : 100 µm,
  • distance between orifices: 100 µm.

Les deux grilles sont ici au contact l'une de l'autre et fixées sur le même support 17. Les deux grilles sont en regard l'une de l'autre et parallèles l'une à l'autre (voir figure 1).The two grids are here in contact with each other and fixed on the same support 17. The two grids are facing each other and parallel to each other (see figure 1 ).

Le support 17 a une forme générale cylindrique à section circulaire dans un plan perpendiculaire à l'axe 13. Les grilles 15 sont par exemple associées au support 17 par surmoulage du support sur les grilles, le support étant réalisée en matière plastique. Le support est lié au tube 5, cette liaison se faisant sur l'ensemble du pourtour de l'extrémité distale du tube.The support 17 has a generally cylindrical shape with a circular section in a plane perpendicular to the axis 13. The grids 15 are for example associated with the support 17 by overmolding the support on the grids, the support being made of plastic. The support is linked to the tube 5, this connection being made over the entire periphery of the distal end of the tube.

Le fonctionnementOperation

Lorsque l'applicateur n'est pas utilisé, le piston 6 est dans sa position la plus basse, c'est-à-dire que son extrémité proximale est au contact de la partie 3 de l'article. Le raisin 14 est situé à distance et en regard de la grille 15 la plus proximale (non illustré).When the applicator is not in use, the piston 6 is in its lowest position, ie its proximal end is in contact with part 3 of the article. The grape 14 is located at a distance from and facing the most proximal grid 15 (not illustrated).

Lors de l'utilisation, l'utilisatrice tient l'article 1 des deux mains, sa première main tenant l'extrémité du tube 5 faisant saillie hors du corps de l'article et son autre main tenant le corps 2 de l'article au niveau de sa portion de plus grande dimension.In use, the user holds the article 1 with both hands, her first hand holding the end of the tube 5 projecting out of the body of the article and her other hand holding the body 2 of the article in the middle. level of its larger portion.

L'utilisatrice applique un mouvement de rotation au corps 2 de l'article par rapport à au tube, autour l'axe 13. Ce mouvement de rotation entraine le parcours de la rampe hélicoïdale 7 de l'élément tubulaire 4 et de la rampe rectiligne 8 du tube 5 par les deux plots de guidage 10 du piston. Ce parcours entraine un mouvement de translation ou coulissement rectiligne du piston 6 suivant l'axe 13, le piston entrainant avec lui le raisin 14. Le mouvement de translation continue jusqu'à ce que le raisin 14 arrive au contact de la grille 15 la plus proximale.The user applies a rotational movement to the body 2 of the article with respect to the tube, around the axis 13. This rotational movement causes the path of the helical ramp 7 of the tubular element 4 and of the rectilinear ramp. 8 of the tube 5 by the two guide pins 10 of the piston. This path causes a translational movement or rectilinear sliding of the piston 6 along the axis 13, the piston bringing with it the grape 14. The translational movement continues until the grape 14 comes into contact with the grid 15 most proximal.

L'utilisatrice continue d'appliquer un mouvement de rotation au corps 2 de l'article faisant ainsi passer l'extrémité du raisin 14 à travers la grille 15 proximale puis la grille 15 distale.The user continues to apply a rotational movement to the body 2 of the article thereby passing the end of the grape 14 through the proximal grid 15 and then the grid 15 distal.

Ce passage à travers les grilles entraine une déstructuration d'une fraction d'extrémité du raisin solide qui est découpée en de fines lamelles qui se réunissent ensuite après le passage des deux grilles, hors de celles-ci et sur la grille distale de sorte à former une pâte homogène. Une fois que la fraction de raisin a traversé les grilles et qu'elle a été déstructurée en pâte, cette pâte est prête à être appliquée. L'utilisatrice peut ainsi aisément appliquer cette pâte sur ses lèvres. Bien entendu, seule l'extrémité du bloc de produit est déstructurée à chaque application, la plus grande partie du raisin gardant son intégrité. Le bloc est progressivement déstructuré au fur et à mesure des applications, tandis qu'il monte vers les grilles.This passage through the grids leads to a destructuring of an end fraction of the solid grape which is cut into thin strips which then meet after the passage of the two grids, out of them and on the distal grid so as to form a homogeneous paste. Once the grape fraction has passed through the grids and has been deconstructed into a paste, this paste is ready to be applied. The user can thus easily apply this paste to her lips. Of course, only the end of the block of product is unstructured for each application, most of the grape retaining its integrity. The block is gradually deconstructed as applications are made, while it rises towards the grids.

La présence de deux grilles au contact l'une de l'autre telle que décrit plus haut présente plusieurs avantages. En effet, cela permet d'avoir une déstructuration du bloc de produit plus importante et d'obtenir ainsi une pâte plus fluide. En outre, notamment si les plus grandes dimensions des orifices 16 de la grille proximale ou amont sont plus grandes que les plus grandes dimensions des orifices 16 de la grille distale ou aval, l'effort à fournir afin de faire traverser les grilles à une partie du raisin est réduit. Le rapport entre ces deux dimensions est supérieur à 1 et inférieur ou égal à 100, et par exemple égal à 60.The presence of two grids in contact with one another as described above has several advantages. In fact, this makes it possible to have a greater destructuring of the block of product and thus to obtain a more fluid dough. In addition, in particular if the largest dimensions of the orifices 16 of the proximal or upstream grid are larger than the largest dimensions of the orifices 16 of the distal or downstream grid, the force to be provided in order to pass the grids through a part of the grape is reduced. The ratio between these two dimensions is greater than 1 and less than or equal to 100, and for example equal to 60.

Ces deux grilles 15 peuvent être de la même matière ou dans des matières différentes. Les deux peuvent en outre avoir des orifices 16 dont les contours ont des formes différentes, que ce soit au sein d'une même grille 15 ou entre les orifices 16 des deux grilles. Par exemple, on peut prévoir une première grille dont les contours des orifices ont une forme rectangulaire et une deuxième grille dont les contours des orifices ont une forme générale oblongue. Bien entendu, un nombre plus grand de grilles peut être envisagé par exemple trois grilles, quatre grilles, cinq grilles ou six grilles.These two grids 15 can be of the same material or of different materials. The two can also have orifices 16 the contours of which have different shapes, whether within the same grid 15 or between the orifices 16 of the two grids. For example, one can provide a first grid whose outlines of the orifices have a rectangular shape and a second grid whose outlines of the orifices have a generally oblong shape. Of course, a larger number of grids can be considered, for example three grids, four grids, five grids or six grids.

Dans un mode de réalisation alternatif présenté à la figure 2, l'article 1 comprend deux grilles 15 qui sont à proximité et en regard l'une de l'autre mais sans contact mutuel cette fois. L'espace entre ces deux grilles est apte à accueillir le raisin après que celui-ci a traversé la première grille, c'est-à-dire la grille proximale et avant son passage à travers la deuxième grille. L'espacement entre ces deux grilles peut être maintenu par exemple par des entretoises.In an alternative embodiment presented in figure 2 , article 1 comprises two grids 15 which are close to and facing each other but without mutual contact this time. The space between these two grids is suitable for receiving the grape after the latter has passed through the first grid, that is to say the proximal grid and before its passage through the second grid. The spacing between these two grids can be maintained for example by spacers.

Les avantages de ce mode de réalisation sont les mêmes que ceux du mode de réalisation précédent. Il permet donc l'obtention d'une pâte de produit plus fluide et de diminuer l'effort à fournir par l'utilisatrice pour passer du raisin solide à la pâte fluide. Comme précédemment, un nombre plus grand de grilles peut être envisagé par exemple trois grilles, quatre grilles, cinq grilles ou six grilles. Ces deux grilles 15 peuvent être de la même matière ou dans des matières différentes. Les deux peuvent en outre avoir des orifices 16 dont les contours ont des formes différentes, que ce soit au sein d'une même grille 15 ou entre les orifices 16 de deux grilles. Par exemple, on peut prévoir une première grille dont les contours des orifices ont une forme rectangulaire et une deuxième grille dont les contours des orifices ont une forme générale oblongue.The advantages of this embodiment are the same as those of the previous embodiment. It therefore makes it possible to obtain a paste of more fluid product and to reduce the effort required by the user to switch from solid grapes to fluid paste. As before, a larger number of grids can be envisaged, for example three grids, four grids, five grids or six grids. These two grids 15 can be of the same material or of different materials. Both may furthermore have orifices 16, the contours of which have different shapes, whether within the same grid 15 or between the orifices 16 of two grids. For example, one can provide a first grid whose outlines of the orifices have a rectangular shape and a second grid whose outlines of the orifices have a generally oblong shape.

Bien entendu, on pourra apporter à l'invention de nombreuses modifications, pourvu que lesdites modifications tombent sous la portée des revendications annexées.Of course, numerous modifications can be made to the invention, provided that said modifications fall within the scope of the appended claims.

Les modes de réalisation présentés utilisent un mécanisme permettant de mouvoir le raisin. Tout autre mécanisme connu de l'homme du métier pourrait être utilisé. Par exemple, les rampes rectilignes peuvent s'étendre à l'extérieur de la pièce portant la rampe hélicoïdale. Toutefois la configuration décrite à l'appui des figures, dans laquelle la rampe hélicoïdale est à l'extérieur des rampes rectilignes, permet de donner un pas réduit à l'hélice et donc de réduire l'effort à fournir par l'utilisatrice pour faire passer le raisin à travers les grilles.The embodiments presented use a mechanism for moving the grape. Any other mechanism known to those skilled in the art could be used. For example, the rectilinear ramps can extend outside the room carrying the helical ramp. However, the configuration described in support of the figures, in which the helical ramp is outside the rectilinear ramps, makes it possible to give a reduced pitch to the propeller and therefore to reduce the force to be provided by the user to make pass the grapes through the grates.

On peut prévoir un mécanisme permettant à l'utilisatrice de fournir directement un effort de coulissement pour faire monter le raisin.A mechanism can be provided allowing the user to directly provide a sliding force to raise the grape.

On peut aussi prévoir un mécanisme dans lequel le raisin est rigidement fixé au corps et c'est au moins une des grilles qui descend sur le raisin pour le déstructurer.It is also possible to provide a mechanism in which the grape is rigidly fixed to the body and it is at least one of the grids which descends on the grape to deconstruct it.

On peut prévoir que l'une des grilles ne soit pas tissée mais soit réalisée par usinage d'une plaque pour y réaliser des orifices ou encore par une technique de fabrication additive (impression 3D).Provision can be made for one of the grids not to be woven but to be produced by machining a plate in order to make orifices therein or even by an additive manufacturing technique (3D printing).

On peut prévoir que la dimension et/ou la répartition des orifices varie sur la surface d'au moins une des grilles.Provision can be made for the size and / or the distribution of the orifices to vary on the surface of at least one of the grids.

On peut également prévoir que les orifices présentent une dimension supérieure à une autre afin de déstructurer la formule davantage dans une direction.Provision can also be made for the orifices to have one dimension greater than another in order to deconstruct the formula further in one direction.

On peut aussi prévoir que la grille soit concave ou convexe.Provision can also be made for the grid to be concave or convex.

On peut prévoir que la grille est en matière plastique, en tissu ou en métal.Provision can be made for the grid to be made of plastic, fabric or metal.

On peut prévoir que le produit cosmétique est destiné à une autre partie du visage. Il peut notamment être appliqué à l'ensemble du corps. Il peut s'agir d'un produit cosmétique différent d'un rouge à lèvres, par exemple d'un produit de soins.Provision can be made for the cosmetic product to be intended for another part of the face. It can in particular be applied to the whole body. It may be a cosmetic product other than a lipstick, for example a care product.
