Definitions

  • the present invention relates to a device for packaging and applying a liquid composition, in particular a liquid cosmetic composition, comprising solid particles sensitive to a magnetic field, comprising:
  • An applicator adapted to be mounted on the container and having a rod and an applicator head secured to one end of the rod, the rod and the applicator head being adapted to be inserted into the container when the applicator is mounted on the container ;
  • the liquid cosmetic composition comprises a liquid phase and solid particles such as nacres sensitive or not to a magnetic field, the cosmetic composition being intended to be applied to the eyelashes, to the lips, on the nails, on the hair or on the skin of a user.
  • the applicator when the solid particles are sensitive to a magnetic field, the applicator then comprises a magnetic applicator head in order to better load the applicator head and / or guide the solid particles to obtain optical effects at the time of application.
  • the application of the composition as example described in document FR 2 947 432 A1 in the name of the Applicant.
  • Other devices comprise, as magnetic part, a magnet separated from the applicator and used just after application of the composition to create patterns by orienting the solid particles under the effect of the magnetic field of the magnet, as for example described in document FR 2 876 011 Al.
  • solid particles indifferent to a magnetic field is even more widespread since it concerns a very large number of cosmetic formulations. It is indeed widely known to use solid particles in a more or less viscous liquid composition to sometimes form a paste as for most mascaras for example. These solid particles are generally called “fillers” and this goes from nacres to pigments, through some natural or synthetic fibers that are used to obtain various well-known effects.
  • compositions generally comprise at most about 10 to 15% by weight of solid particles. Beyond this, it becomes difficult to disperse them stably and homogeneously in a composition, but also to be able to spread the composition on a surface that it is with the hand and even more with an applicator whose applicator head must be able to be loaded with adequately produced.
  • a homogeneous composition comprising solid particles that remain stable because no or little mobility in the composition and / or if one wants to use a higher concentration of solid particles, it is necessary to to be able to increase the viscosity of the composition.
  • thickeners are generally added to try to obtain the desired viscosity for a given composition.
  • the viscosity of the composition is not well adapted, solid particle clusters will form when it is too high or they will settle at the bottom of the container when it is too low. If the formula becomes too thick, the loading of the applicator head and the spreading of the product then become difficult. It is well known to consumers of cosmetic products in particular and mascara in particular, that it quickly becomes necessary to use the applicator, in particular the stem and the applicator head, as an agitator by making round trips in the container to slightly fluidize the composition to load the applicator head. This practice is not without adverse consequences on the properties of the composition, because it dries more quickly in contact with the air which causes an even faster increase in its viscosity.
  • the present invention aims to overcome these disadvantages by providing a device that allows a application of the liquid composition comprising solid particles, including in large quantities, which is as reproducible as possible and of the most constant quality possible over time, and which is simple to use.

  • the magnetic part of the rod makes it possible to attract on the one hand a sufficient quantity according to the desired application of solid particles sensitive to a magnetic field which then accumulate on the rod of the applicator by coming saturating the magnetic part in solid particles.
  • the extraction of the applicator from the container makes it possible to release the solid particles accumulated on the rod by contact with the organ of cleaning, these solid particles then locally and momentarily modify the viscosity of the liquid phase in the vicinity of the stem and especially the applicator head.
  • the device according to the invention thus makes it possible, in a manner and in situ for each use, to temporarily and locally modify the viscosity of the composition, which has a great many advantages.
  • this allows the applicator head to be loaded with a cosmetic composition comprising a large and reproducible quantity of solid particles dispersed in the liquid phase, the higher viscosity of which is better suited to a deposit on a surface, especially in the use in cosmetics, and especially on keratinous fibers.

ARRIERE-PLAN DE L'INVENTION  BACKGROUND OF THE INVENTION
On connaît dans le domaine cosmétique des dispositifs de ce type dans lesquels la composition cosmétique liquide comprend une phase liquide et des particule solides comme des nacres sensibles ou non à un champ magnétique, la composition cosmétique étant destinée à être appliquée sur les cils, sur les lèvres, sur les ongles, sur les cheveux ou encore sur la peau d'une utilisatrice .  In the field of cosmetics, devices of this type are known in which the liquid cosmetic composition comprises a liquid phase and solid particles such as nacres sensitive or not to a magnetic field, the cosmetic composition being intended to be applied to the eyelashes, to the lips, on the nails, on the hair or on the skin of a user.
D'une manière générale, lorsque les particules solides sont sensibles à un champ magnétique, 1 ' applicateur comprend alors une tête applicatrice aimantée afin de mieux charger la tête applicatrice et/ou d'orienter les particules solides pour obtenir des effets optiques au moment de l'application de la composition, comme par exemple décrit dans le document FR 2 947 432 Al au nom de la Demanderesse. D'autres dispositifs comprennent, comme partie magnétique, un aimant séparé de 1 ' applicateur et utilisé juste après application de la composition pour créer des motifs en orientant les particules solides sous l'effet du champ magnétique de l'aimant, comme par exemple décrit dans le document FR 2 876 011 Al. In general, when the solid particles are sensitive to a magnetic field, the applicator then comprises a magnetic applicator head in order to better load the applicator head and / or guide the solid particles to obtain optical effects at the time of application. the application of the composition, as example described in document FR 2 947 432 A1 in the name of the Applicant. Other devices comprise, as magnetic part, a magnet separated from the applicator and used just after application of the composition to create patterns by orienting the solid particles under the effect of the magnetic field of the magnet, as for example described in document FR 2 876 011 Al.
Le cas des particules solides indifférentes à un champ magnétique est encore plus répandu puisqu'il concerne un très grand nombre de formulations cosmétiques. Il est en effet très largement connu d'utiliser des particules solides dans une composition liquide plus ou moins visqueuse jusqu'à former parfois une pâte comme pour la majorité des mascaras par exemple. Ces particules solides sont généralement appelées « charges » et cela va des nacres aux pigments, en passant par certaines fibres naturelles ou synthétiques qui sont utilisées pour obtenir divers effets bien connus.  The case of solid particles indifferent to a magnetic field is even more widespread since it concerns a very large number of cosmetic formulations. It is indeed widely known to use solid particles in a more or less viscous liquid composition to sometimes form a paste as for most mascaras for example. These solid particles are generally called "fillers" and this goes from nacres to pigments, through some natural or synthetic fibers that are used to obtain various well-known effects.
Toutefois, l'emploi de ces particules solides, sensibles ou non à un champ magnétique, se heurte à des problèmes techniques récurrents et connexes qui ont trait à la concentration maximale possible de ces particules solides dans une composition donnée, à la possibilité de pouvoir ensuite déposer une telle composition sur une surface, ainsi qu'au dessèchement de telles compositions qui sont en général relativement visqueuses et donc particulièrement sensibles à ce dernier phénomène.  However, the use of these solid particles, whether or not sensitive to a magnetic field, faces recurrent and related technical problems which relate to the maximum possible concentration of these solid particles in a given composition, to the possibility of being able to then depositing such a composition on a surface, and the drying of such compositions which are generally relatively viscous and therefore particularly sensitive to the latter phenomenon.
En effet, de telles compositions comprennent en général au maximum environ 10 à 15% en poids de particules solides. Au-delà, il devient difficile de les disperser de manière stable et homogène dans une composition, mais aussi de pouvoir étaler la composition sur une surface que ce soit avec la main et encore plus avec un applicateur dont la tête applicatrice doit pouvoir être chargée en produit de manière adéquate. En pratique, si l'on veut pouvoir disposer d'une composition homogène comprenant des particules solides qui restent bien stables car pas ou peu mobiles dans la composition et/ou si l'on veut utiliser une concentration en particules solides plus importante, il faut pouvoir augmenter la viscosité de la composition. Indeed, such compositions generally comprise at most about 10 to 15% by weight of solid particles. Beyond this, it becomes difficult to disperse them stably and homogeneously in a composition, but also to be able to spread the composition on a surface that it is with the hand and even more with an applicator whose applicator head must be able to be loaded with adequately produced. In practice, if one wants to be able to have a homogeneous composition comprising solid particles that remain stable because no or little mobility in the composition and / or if one wants to use a higher concentration of solid particles, it is necessary to to be able to increase the viscosity of the composition.
Pour cela, on ajoute généralement des épaississants pour essayer d'obtenir la viscosité souhaitée pour une composition donnée.  For this, thickeners are generally added to try to obtain the desired viscosity for a given composition.
Si la viscosité de la composition n'est pas bien adaptée, des amas de particules solides vont se former lorsqu'elle est trop élevée ou bien ces dernières vont sédimenter au fond du récipient lorsqu'elle est trop faible. Si la formule devient trop épaisse, le chargement de la tête applicatrice et l'étalement du produit deviennent alors difficiles. Il est bien connu des consommatrices de produits cosmétiques notamment et de mascara en particulier, qu'il devient assez vite nécessaire d'utiliser 1 ' applicateur , en particulier la tige et la tête applicatrice, comme un agitateur en faisant des aller- retours dans le récipient pour fluidifier un peu la composition afin de charger la tête applicatrice. Cette pratique n'est toutefois pas sans conséquences néfastes sur les propriétés de la composition, car elle l'assèche plus rapidement au contact de l'air ce qui engendre une augmentation encore plus rapide de sa viscosité.  If the viscosity of the composition is not well adapted, solid particle clusters will form when it is too high or they will settle at the bottom of the container when it is too low. If the formula becomes too thick, the loading of the applicator head and the spreading of the product then become difficult. It is well known to consumers of cosmetic products in particular and mascara in particular, that it quickly becomes necessary to use the applicator, in particular the stem and the applicator head, as an agitator by making round trips in the container to slightly fluidize the composition to load the applicator head. This practice is not without adverse consequences on the properties of the composition, because it dries more quickly in contact with the air which causes an even faster increase in its viscosity.
Ainsi, il devient donc au fil des utilisations de plus en plus difficile, et au bout d'un moment impossible, de maintenir un chargement optimal de la tête applicatrice en produit contenant des particules solides. Dans le cas d'un mascara, un pourcentage non négligeable du produit initialement vendu devient même inutilisable et donc perdu.  Thus, it becomes more and more difficult, and after an impossible time, to maintain optimal loading of the applicator head product containing solid particles. In the case of a mascara, a significant percentage of the product initially sold becomes even unusable and therefore lost.
OBJETS DE L'INVENTION  OBJECTS OF THE INVENTION
La présente invention a pour but de pallier ces inconvénients en proposant un dispositif qui permette une application de la composition liquide comprenant des particules solides, y compris en quantité très importante, qui soit la plus reproductible possible et d'une qualité la plus constante possible au fil du temps, et qui soit simple à utiliser. The present invention aims to overcome these disadvantages by providing a device that allows a application of the liquid composition comprising solid particles, including in large quantities, which is as reproducible as possible and of the most constant quality possible over time, and which is simple to use.
A cet effet, l'invention a pour objet un dispositif de conditionnement et d'application d'une composition liquide comprenant des particules solides sensibles à un champ magnétique du type précité, caractérisé en ce que la tige de 1 ' applicateur comprend une partie magnétique apte à générer un champ magnétique adapté pour attirer et maintenir sur la tige, au moins dans une position de repos, au moins une partie desdites particules solides, ladite partie magnétique s 'étendant au moins sur une partie d'une zone de la tige qui s'étend entre la tête applicatrice et l'organe de nettoyage lorsque 1 ' applicateur est monté sur le récipient .  For this purpose, the subject of the invention is a device for packaging and applying a liquid composition comprising solid particles sensitive to a magnetic field of the aforementioned type, characterized in that the rod of the applicator comprises a magnetic part. adapted to generate a magnetic field adapted to attract and maintain on the rod, at least in a rest position, at least a portion of said solid particles, said magnetic portion extending at least over a portion of an area of the rod which extends between the applicator head and the cleaning member when the applicator is mounted on the container.
Grâce à ces dispositions, la partie magnétique de la tige permet d'attirer d'une part une quantité suffisante selon l'application souhaitée de particules solides sensibles à un champ magnétique qui s'accumulent alors sur la tige de 1 ' applicateur en venant saturer la partie magnétique en particules solides.  Thanks to these provisions, the magnetic part of the rod makes it possible to attract on the one hand a sufficient quantity according to the desired application of solid particles sensitive to a magnetic field which then accumulate on the rod of the applicator by coming saturating the magnetic part in solid particles.
D'autre part, si des particules solides sont présentes en excès, elles peuvent sédimenter au fond du récipient grâce à leur mobilité dans la phase liquide en échappant à l'influence du champ magnétique de la partie magnétique. Cet excès de particules solides peut aussi constituer une réserve en vue d'utilisations futures afin de permettre un usage optimal prolongé en fixant le plus longtemps possible sur la partie magnétique de la tige une quantité efficace de particules solides.  On the other hand, if solid particles are present in excess, they can sediment at the bottom of the container due to their mobility in the liquid phase while escaping the influence of the magnetic field of the magnetic part. This excess of solid particles can also constitute a reserve for future uses to allow a prolonged optimal use by fixing as long as possible on the magnetic part of the rod an effective amount of solid particles.
Enfin, l'extraction de 1 ' applicateur hors du récipient permet de libérer les particules solides accumulées sur la tige par contact avec l'organe de nettoyage, ces particules solides venant alors modifier localement et momentanément la viscosité de la phase liquide au voisinage de la tige et surtout de la tête applicatrice . Finally, the extraction of the applicator from the container makes it possible to release the solid particles accumulated on the rod by contact with the organ of cleaning, these solid particles then locally and momentarily modify the viscosity of the liquid phase in the vicinity of the stem and especially the applicator head.
Le dispositif selon l'invention permet donc à façon et in situ à chaque utilisation de modifier temporairement et localement la viscosité de la composition, ce qui présente de très nombreux avantages.  The device according to the invention thus makes it possible, in a manner and in situ for each use, to temporarily and locally modify the viscosity of the composition, which has a great many advantages.
Tout d'abord, cela permet le chargement de la tête applicatrice avec une composition cosmétique comprenant une quantité importante et reproductible de particules solides dispersées dans la phase liquide dont la viscosité plus élevée est mieux adaptée à un dépôt sur une surface, notamment dans le cadre d'une utilisation en cosmétique, et tout particulièrement sur des fibres kératiniques .  Firstly, this allows the applicator head to be loaded with a cosmetic composition comprising a large and reproducible quantity of solid particles dispersed in the liquid phase, the higher viscosity of which is better suited to a deposit on a surface, especially in the use in cosmetics, and especially on keratinous fibers.
De plus, cette augmentation de viscosité, qui dépend de la fraction volumique de particules solides qui se dispersent dans la phase liquide, n'ayant lieu qu'au moment du chargement de la tête applicatrice dans le cadre d'une utilisation, il est possible d'utiliser une phase liquide de viscosité inférieure. Une telle phase liquide permet d'ajouter une quantité de particules solides nettement supérieure aux quantités connues de l'art antérieur et de pouvoir disposer d'un dispositif de conditionnement et d'application nettement moins sensible au phénomène de dessèchement.  In addition, this increase in viscosity, which depends on the volume fraction of solid particles that disperse in the liquid phase, takes place only at the time of loading of the applicator head in the context of use, it is possible to use a liquid phase of lower viscosity. Such a liquid phase makes it possible to add a quantity of solid particles which is clearly greater than the known quantities of the prior art and to have a packaging and application device which is clearly less sensitive to the phenomenon of drying out.

DESCRIPTION PLUS DETAILLEE  DESCRIPTION DETAILED
Sur les différentes Figures, les mêmes références désignent des éléments identiques ou similaires.  In the various figures, the same references designate identical or similar elements.
La Figure 1 illustre un dispositif 10 de conditionnement et d'application d'une composition liquide selon un premier mode de réalisation de l'invention et dans une position initiale de repos ou hors utilisation, la composition liquide comprenant des particules solides sensibles à un champ magnétique et étant ici du mascara destiné à être appliqué sur les cils d'une utilisatrice.  FIG. 1 illustrates a device 10 for packaging and applying a liquid composition according to a first embodiment of the invention and in an initial position of rest or out of use, the liquid composition comprising solid particles sensitive to a field magnetic and here being mascara intended to be applied to the eyelashes of a user.
Le dispositif 10 comprend un récipient 12 contenant le mascara 14 et un applicateur 16 monté sur le récipient 12.  The device 10 comprises a container 12 containing the mascara 14 and an applicator 16 mounted on the container 12.
Le récipient 12 comprend un corps 18 et un col 20 s 'étendant dans le prolongement du corps 18 en formant un décrochement par rapport au corps 18. Dans l'exemple considéré, le corps 18 présente une forme sensiblement cylindrique d'axe Z et une section transversale sensiblement carrée. The container 12 comprises a body 18 and a neck 20 extending in the extension of the body 18 forming a recess relative to the body 18. In the example considered, the body 18 has a substantially cylindrical shape Z axis and a substantially square cross section.
Le col 10, de forme sensiblement cylindrique d'axe Z et de section transversale sensiblement circulaire, comporte un filetage extérieur 22.  The neck 10, substantially cylindrical in shape of Z axis and of substantially circular cross section, has an external thread 22.
Avantageusement, le récipient 12 est fabriqué à partir d'un matériau sensiblement transparent ou translucide, par exemple un verre ou une matière plastique telle qu'un polyéthylène téréphtalate (PET) ou un polyamide (PA) .  Advantageously, the container 12 is made from a substantially transparent or translucent material, for example a glass or a plastic material such as a polyethylene terephthalate (PET) or a polyamide (PA).
L ' applicateur 16 comprend un bouchon 24, une tige 26 et une tête applicatrice 28.  The applicator 16 comprises a plug 24, a rod 26 and an applicator head 28.
Le bouchon 24 comprend une jupe intérieure 30 de forme sensiblement cylindrique d'axe Z et de section transversale sensiblement circulaire, et munie d'un filetage intérieur 32 complémentaire du filetage extérieur 22 du col 10 afin de visser le bouchon 24 sur le col 10 et obturer le récipient 12 de manière étanche.  The plug 24 comprises an inner skirt 30 of substantially cylindrical shape with a Z axis and a substantially circular cross section, and provided with an internal thread 32 complementary to the external thread 22 of the neck 10 in order to screw the plug 24 onto the neck 10 and seal the container 12 in a sealed manner.
La jupe intérieure 30 est entourée par une jupe extérieure 34 de forme sensiblement cylindrique d'axe Z et de section transversale identique à celle du corps 18. La présence de la jupe extérieure 34 est optionnelle car cette jupe a un rôle essentiellement esthétique.  The inner skirt 30 is surrounded by an outer skirt 34 of substantially cylindrical shape Z axis and cross section identical to that of the body 18. The presence of the outer skirt 34 is optional because this skirt has an essentially aesthetic role.
Les jupes intérieure 30 et extérieure 34 sont surmontées d'un organe de préhension 36.  The inner and outer skirts 34 are surmounted by a gripping member 36.
La tige 26 comprend un tube creux 38 qui s'étend entre le bouchon 24 et la tête applicatrice 28 et qui pénètre à l'intérieur du récipient 12 lorsque le bouchon 24 obture le récipient 12. En particulier, le tube 38 s'étend suivant l'axe Z entre une extrémité proximale 38a et une extrémité distale 38b, et présente par exemple une section transversale sensiblement circulaire et constante suivant l'axe Z.  The rod 26 comprises a hollow tube 38 which extends between the plug 24 and the applicator head 28 and which penetrates inside the receptacle 12 when the plug 24 closes the receptacle 12. In particular, the tube 38 extends according to the Z axis between a proximal end 38a and a distal end 38b, and for example has a substantially circular cross section and constant along the Z axis.
Le tube 38 présente par exemple une longueur sensiblement égale à 50 mm et un diamètre extérieur sensiblement égal à 4,4 mm. The tube 38 has for example a length substantially equal to 50 mm and an outer diameter substantially equal to 4.4 mm.
L'extrémité proximale 38a du tube 38 est solidaire du bouchon 24 tandis que la tête applicatrice 28 est solidaire de l'extrémité distale 38b.  The proximal end 38a of the tube 38 is integral with the plug 24 while the applicator head 28 is integral with the distal end 38b.
Dans le mode de réalisation décrit ici, la tête applicatrice 28 est formée par un faisceau de poils formant un pinceau.  In the embodiment described here, the applicator head 28 is formed by a bundle of bristles forming a brush.
En variante, la tête applicatrice peut être formée par un peigne, une brosse, une mousse, un embout fileté, un embout floqué ou tout autre moyen apte à exercer une fonction analogue.  Alternatively, the applicator head may be formed by a comb, a brush, a foam, a threaded tip, a flocked tip or any other means capable of performing a similar function.
Le dispositif 10 comprend un organe de nettoyage 40 de la tige 26 disposé dans le récipient 12 au niveau du décrochement formé entre le corps 18 et le col 20. L'organe de nettoyage 40 permet de libérer des particules solides se trouvant sur la tige 26 de 1 ' applicateur 16 lors de son extraction du récipient 12 comme cela sera expliqué plus en détail ultérieurement, ce qui permet d'agiter les particules solides dans la phase liquide de la composition cosmétique, ici le mascara 14, au voisinage de la tige 26 et de la tête applicatrice 28. Grâce à ces dispositions, la viscosité de la composition liquide est ainsi momentanément et localement augmentée, ce qui permet de mieux charger la tête applicatrice 28 en particules solides et de limiter les phénomènes générant un dessèchement de la composition cosmétique .  The device 10 comprises a cleaning member 40 of the rod 26 disposed in the container 12 at the recess formed between the body 18 and the neck 20. The cleaning member 40 releases solid particles on the rod 26 of the applicator 16 during its extraction from the container 12 as will be explained in more detail later, which makes it possible to stir the solid particles in the liquid phase of the cosmetic composition, here the mascara 14, in the vicinity of the stem 26 and the applicator head 28. Thanks to these provisions, the viscosity of the liquid composition is thus momentarily and locally increased, which makes it possible to better load the applicator head 28 in solid particles and to limit the phenomena generating drying of the cosmetic composition. .
Selon une variante préférée, l'organe de nettoyage 40 est un manchon inséré dans le col 20 du récipient 12 et fabriqué à partir d'un matériau relativement souple obturant le col 20 et se déformant élastiquement au passage de 1 ' applicateur 16.  According to a preferred variant, the cleaning member 40 is a sleeve inserted in the neck 20 of the container 12 and made from a relatively flexible material closing the neck 20 and elastically deforming the passage of the applicator 16.
Dans l'exemple considéré, l'organe de nettoyage 40 est constitué d'une mousse souple mais il est possible d'utiliser tout type d'essoreur habituellement utilisé en cosmétique . In the example considered, the cleaning member 40 is made of a flexible foam but it is possible to use any type of wiper usually used in cosmetic.
En variante, l'organe de nettoyage 40 peut être formé directement par le col 20 du récipient 12.  Alternatively, the cleaning member 40 may be formed directly by the neck 20 of the container 12.
Afin de pouvoir stocker momentanément sur la tige 26 des particules solides contenues dans le mascara 14, la tige 26 comprend une partie magnétique 42 apte à générer un champ magnétique adapté pour attirer et maintenir sur la tige, au moins dans la position de repos, au moins une partie des particules solides.  In order to temporarily store on the rod 26 solid particles contained in the mascara 14, the rod 26 comprises a magnetic portion 42 capable of generating a magnetic field adapted to attract and hold on the rod, at least in the rest position, to least part of the solid particles.
Par « partie magnétique » on entend une partie apte à générer un champ magnétique, qu'elle soit aimantée ou aimantable .  By "magnetic part" is meant a portion capable of generating a magnetic field, whether magnetized or magnetizable.
La partie magnétique 42 est située entre le bouchon 24 et la tête applicatrice 28. Plus particulièrement, la partie magnétique 42 s'étend au moins sur une partie d'une zone 46 de la tige 26 qui s'étend entre la tête applicatrice 28 et l'organe de nettoyage 40 lorsque 1 ' applicateur 16 est monté sur le récipient 12.  The magnetic portion 42 is located between the plug 24 and the applicator head 28. More particularly, the magnetic portion 42 extends over at least a portion of an area 46 of the rod 26 which extends between the applicator head 28 and the cleaning member 40 when the applicator 16 is mounted on the container 12.
Dans le premier mode de réalisation de la Figure 1, la partie magnétique 42 comprend un aimant plein 44 disposé sur un tronçon central 47 de la zone 46 de la tige 26. On considère alors que la partie magnétique s'étend seulement sur une partie de la zone 46 de la tige 26 de manière continue .  In the first embodiment of Figure 1, the magnetic portion 42 comprises a solid magnet 44 disposed on a central portion 47 of the zone 46 of the rod 26. It is then considered that the magnetic portion extends only over a portion of the zone 46 of the rod 26 in a continuous manner.
L'aimant 44 présente une forme sensiblement cylindrique, par exemple de longueur comprise entre 10 et 12 mm, et une section transversale sensiblement circulaire, par exemple de 2 mm de diamètre. En variante, l'aimant 44 peut présenter une forme quelconque appropriée, par exemple parallélépipédique, triangulaire, etc.  The magnet 44 has a substantially cylindrical shape, for example of length between 10 and 12 mm, and a substantially circular cross section, for example 2 mm in diameter. Alternatively, the magnet 44 may have any suitable shape, for example parallelepiped, triangular, etc.
L'aimant 44 peut être emmanché ou collé à l'intérieur du tube 38.  The magnet 44 can be fitted or glued inside the tube 38.
En variante, l'aimant 44 est surmoulé lors de la fabrication de la tige 26.  Alternatively, the magnet 44 is overmolded during the manufacture of the rod 26.
L'aimant 44 est de préférence un aimant permanent fabriqué à partir d'un matériau ferromagnétique ou à partir d'un matériau comprenant des particules magnétiques ou magnétisables . The magnet 44 is preferably a permanent magnet manufactured from a ferromagnetic material or from a material comprising magnetic or magnetizable particles.
On entend par « particules magnétiques ou magnétisables » des particules présentant une susceptibilité magnétique non nulle, c'est-à-dire sensibles à l'action d'un champ magnétique.  The term "magnetic particles or magnetizable particles" having a non-zero magnetic susceptibility, that is to say sensitive to the action of a magnetic field.
L'aimant 44 est apte à générer un champ magnétique orienté suivant l'axe Z ou non.  The magnet 44 is able to generate a magnetic field oriented along the Z axis or not.
La composition cosmétique 14 comprend une phase liquide 48 et des particules solides 52 sensibles à un champ magnétique.  The cosmetic composition 14 comprises a liquid phase 48 and solid particles 52 sensitive to a magnetic field.
La phase liquide 48 est une dispersion aqueuse desdites particules solides 52 dans un polymère filmogène hydrosoluble ou hydrodispersible de type acrylique et/ou polyacrylique ou un mélange de tels polymères filmogènes.  The liquid phase 48 is an aqueous dispersion of said solid particles 52 in a water-soluble or water-dispersible film-forming polymer of acrylic and / or polyacrylic type or a mixture of such film-forming polymers.
De manière générale, la dispersion aqueuse comprend en pourcentage en poids par rapport au poids total de la dispersion aqueuse :  In general, the aqueous dispersion comprises in percentage by weight relative to the total weight of the aqueous dispersion:
- qsp eau ;  - qsp water;
5 à 90% au moins d'un polymère ou d'un mélange de polymères de type acrylates et/ou polyacrylates comme agent filmogène, mieux de 20 à 50%, encore mieux de 30 à 40% ; et de manière facultative  At least 5 to 90% of a polymer or a mixture of polymers of acrylate and / or polyacrylate type as film-forming agent, more preferably 20 to 50%, more preferably 30 to 40%; and optionally
- 1 à 30% au moins d'un sucre en Ce ou C12 comme agent plastifiant, mieux de 5 à 15% ; et/ou At least 1 to 30% of a sugar in Ce or C 1 2 as a plasticizer, better still 5 to 15%; and or
0 à 15% d'alcool éthylique.  0 to 15% of ethyl alcohol.
La phase liquide 48 présente une viscosité comprise entre 5xl0~3 Pa.s et 5xl0_1 Pa.s, ces valeurs ayant été obtenues par des mesures rhéologiques réalisées sur un rhéomètre ARES-G2 à une vitesse de 100 CIÎT1 et dans une cuve de 30 mL avec ailettes. Cette gamme de viscosités exclut donc les compositions cosmétiques pâteuses dans lesquelles les particules solides y sont dispersées de manière stable donc sensiblement immobile et permet de contenir une concentration plus importante de particules solides . The liquid phase 48 has a viscosity of 3 Pa.s and 5xl0 ~ 5xl0 _1 Pa.s, these values having been obtained by rheological measurements performed on an ARES-G2 rheometer at a speed of 100 CIIT 1 and in a tank 30 mL with fins. This range of viscosities thus excludes pasty cosmetic compositions in which the solid particles are stably dispersed therein and therefore substantially immobile and allows contain a higher concentration of solid particles.
La phase liquide 48 comprend ainsi de l'eau, un polymère filmogène, un plastifiant de type sucre, un alcool et un conservateur.  The liquid phase 48 thus comprises water, a film-forming polymer, a sugar-type plasticizer, an alcohol and a preservative.
Le polymère est indispensable pour pouvoir créer un film sur les cils. Il peut être choisi parmi les polymères hydrosolubles ou hydrodispersibles comme les latex qui sont des polymères filmogènes de type acrylates/polyacrylates, les polymères et copolymères de vinylpyrrolidones et les alcools polyvinyliques , soit plus généralement dans toute la famille des acryliques. Bien entendu, il peut s'agir aussi d'un mélange de polymères filmogènes. De préférence, le polymère choisi est transparent en masse afin de bien visualiser les particules solides et d'améliorer ainsi l'esthétisme du produit. De tels polymères peuvent être par exemple ceux commercialisés sous les noms Syntran®, Covacryl®, Ultrasol® et Daitosol®.  The polymer is essential to create a film on the eyelashes. It may be chosen from water-soluble or water-dispersible polymers such as latexes which are film-forming polymers of the acrylate / polyacrylate type, polymers and copolymers of vinylpyrrolidones and polyvinyl alcohols, or more generally in the entire family of acrylics. Of course, it may also be a mixture of film-forming polymers. Preferably, the chosen polymer is transparent in bulk so as to clearly visualize the solid particles and thus improve the aesthetics of the product. Such polymers may be for example those marketed under the names Syntran®, Covacryl®, Ultrasol® and Daitosol®.
Le plastifiant est indispensable ou facultatif selon la nature du polymère. Afin d'avoir un film intéressant, il est indispensable d'avoir un plastifiant associé au polymère filmogène. Le plastifiant peut être un polyol qui peut être choisi parmi les sucres et leurs dérivés, en particulier leurs esters ou leurs éthers. Le sucre est par exemple choisi parmi les sucres en C6 et les sucres en C12. Un sucre en C6 peut être le glucose, le sorbitol, le mannitol ou le galactitol. Un sucre en C12 peut être le saccharose ou le lactitol. Le polyol peut être choisi parmi les polyalkylène-glycols , notamment les poly ( oxyalkylène en C2-C5) et plus particulièrement un poly(oxyde d'éthylène) et/ou un poly(oxyde de propylène) . Le polyol est de préférence choisi parmi le glycérol, le sorbitol et les glycols. Selon un mode de réalisation avantageux, le polyol est le sorbitol, par exemple celui commercialisé sous le nom Néosorb 70/02®. L'alcool éthylique n'est pas indispensable mais sa présence permet d'accélérer le séchage de la composition. The plasticizer is indispensable or optional depending on the nature of the polymer. In order to have an interesting film, it is essential to have a plasticizer associated with the film-forming polymer. The plasticizer may be a polyol which may be chosen from sugars and their derivatives, in particular their esters or their ethers. The sugar is, for example, chosen from C 6 sugars and C 1 2 sugars. A C 6 sugar may be glucose, sorbitol, mannitol or galactitol. A C 1 2 sugar may be sucrose or lactitol. The polyol may be chosen from polyalkylene glycols, in particular poly (oxyalkylene C2-C5) and more particularly poly (ethylene oxide) and / or poly (propylene oxide). The polyol is preferably selected from glycerol, sorbitol and glycols. According to an advantageous embodiment, the polyol is sorbitol, for example that marketed under the name Neosorb 70 / 02®. Ethyl alcohol is not essential, but its presence makes it possible to accelerate the drying of the composition.
Le conservateur est vivement recommandé. Les plus couramment utilisés sont le phénoxyéthanol mais aussi les parahydroxy benzoates de méthyl, d'éthyl, de propyl ou de butyl et l'acide sorbique.  The curator is highly recommended. The most commonly used are phenoxyethanol but also parahydroxy benzoates of methyl, ethyl, propyl or butyl and sorbic acid.
Ainsi, de manière générale, la composition liquide 14 comprend en pourcentage en poids par rapport au poids total de la composition liquide 14 :  Thus, in general, the liquid composition 14 comprises in percentage by weight relative to the total weight of the liquid composition 14:
- qsp eau ;  - qsp water;
5 à 90% au moins d'un polymère ou d'un mélange de polymères de type acrylates et/ou polyacrylates comme agent filmogène, mieux de 20 à 50%, encore mieux de 30 à 40% ;  At least 5 to 90% of a polymer or a mixture of polymers of acrylate and / or polyacrylate type as film-forming agent, more preferably 20 to 50%, more preferably 30 to 40%;
- 0,5 à 50% de particules solides 52 sensibles à un champ magnétique, mieux de 0,5 à 20%, encore mieux de 10 à 15% ; et de manière facultative  0.5 to 50% of solid particles 52 sensitive to a magnetic field, better still from 0.5 to 20%, more preferably from 10 to 15%; and optionally
l à 30% au moins d'un sucre en C6 ou C12 comme agent plastifiant, mieux de 5 à 15% ; et/ou  at least 30% of a C6 or C12 sugar as plasticizer, better still 5 to 15%; and or
- 0 à 15% d'alcool éthylique.  0 to 15% of ethyl alcohol.
Les particules solides 52 sont des particules magnétiques ou magnétisables qui sont sensibles à un champ magnétique et qui sont adaptées pour être attirées par l'aimant 44.  The solid particles 52 are magnetic or magnetizable particles which are sensitive to a magnetic field and which are adapted to be attracted by the magnet 44.
Les particules solides 52 peuvent comprendre tout matériau magnétique tel que le nickel, le cobalt, le fer, leurs alliages et oxydes, notamment l'oxyde de fer Fe304. The solid particles 52 may comprise any magnetic material such as nickel, cobalt, iron, their alloys and oxides, especially iron oxide Fe 3 O 4 .
Avantageusement, les particules solides 52 présentent également des propriétés optiques de réflexion et/ou de diffraction de la lumière, en particulier lorsque la phase liquide 48 est transparente ou translucide.  Advantageously, the solid particles 52 also have optical properties of reflection and / or diffraction of light, in particular when the liquid phase 48 is transparent or translucent.
De préférence, les particules solides 52 sont des nacres magnétiques comportant de l'oxyde de fer Fe304. Par exemple, les associations suivantes sont possibles : mica/oxyde de fer, mica/titane/oxyde de fer, borosilicate/oxyde de fer, borosilicate/titane/oxyde de fer, silice/oxyde de fer, aluminium/silice/oxyde de fer et alumine/oxyde de fer. De telles nacres sont par exemple commercialisées sous les noms Colorona Blackstar®, Cloisonné Nu Antique®, Sunpearl Shadow®, Refecks Blackened®, Sunprizma®, Mica Black®. Preferably, the solid particles 52 are magnetic nacres comprising Fe 3 O 4 iron oxide. For example, the following combinations are possible: mica / iron oxide, mica / titanium / iron oxide, borosilicate / iron oxide, borosilicate / titanium / iron oxide, silica / iron oxide, aluminum / silica / iron oxide and alumina / iron oxide. Such nacres are for example marketed under the names Colorona Blackstar®, Naked Cloisonne Antique®, Sunpearl Shadow®, Refecks Blackened®, Sunprizma®, Mica Black®.
La dimension des particules solides 52 est comprise entre 0,1 et 700pm.  The size of the solid particles 52 is between 0.1 and 700 μm.
La composition liquide 14 peut être obtenue par dispersion des différents éléments à l'aide d'un mélangeur de type Rayneri. Dans une première phase, on mélange de l'eau, le polymère, le plastifiant, l'alcool et le conservateur à 350 tr/min pendant 30 minutes. Lorsque la phase obtenue est bien homogène, on ajoute les nacres à 350 tr/min et on mélange pendant 10 minutes. En préambule à ce mode opératoire, si le plastifiant est un sucre, il peut être nécessaire de le chauffer au préalable si celui-ci est légèrement cristallisé afin de le ré-homogénéiser .  The liquid composition 14 can be obtained by dispersing the various elements using a Rayneri type mixer. In a first phase, water, the polymer, the plasticizer, the alcohol and the preservative are mixed at 350 rpm for 30 minutes. When the phase obtained is homogeneous, the nacres are added at 350 rpm and mixed for 10 minutes. In the preamble to this procedure, if the plasticizer is a sugar, it may be necessary to heat it beforehand if it is slightly crystallized in order to re-homogenize it.
En variante, les particules solides 52 peuvent être des fibres chargées en oxyde de fer.  Alternatively, the solid particles 52 may be fibers loaded with iron oxide.
Les propriétés magnétiques de l'aimant 44 sont avantageusement choisies en fonction de la viscosité du milieu, de la nature ou composition des particules solides 52, de leur sensibilité magnétique et/ou de leur concentration, de manière à exercer sur les particules solides 52 une force d'attraction suffisante pour les attirer et les maintenir sur la tige 26 au moins lorsque la tige 26 est au repos dans le récipient 12.  The magnetic properties of the magnet 44 are advantageously chosen according to the viscosity of the medium, the nature or composition of the solid particles 52, their magnetic sensitivity and / or their concentration, so as to exert on the solid particles 52 a sufficient attraction force to attract and hold them on the rod 26 at least when the rod 26 is at rest in the container 12.

Tableau 2  Table 2
Le fonctionnement du dispositif 10 est expliqué ci- dessous . The operation of the device 10 is explained below.
Initialement, le dispositif 10 est dans la position initiale de repos avant utilisation illustrée sur la Figure 1.  Initially, the device 10 is in the initial rest position before use illustrated in FIG.
Dans cette position, le bouchon 24 est vissé sur le col 20 et obture de manière étanche le récipient 12.  In this position, the plug 24 is screwed onto the neck 20 and sealingly closes the container 12.
La tige 26 et la tête applicatrice 28 trempent dans le mascara 14.  The rod 26 and the applicator head 28 dipped in the mascara 14.
Une partie des particules solides 52 s'est agglomérée sur la tige 26 au niveau de l'aimant 44, tandis que les autres particules solides 52 reposent au fond du récipient 12.  Part of the solid particles 52 has agglomerated on the rod 26 at the level of the magnet 44, while the other solid particles 52 are at the bottom of the container 12.
Lorsqu'une utilisatrice souhaite appliquer le mascara 14 sur ses cils, elle saisit l'organe de préhension 36, dévisse le bouchon 24 et extrait la tige 26 du récipient 12 sans agitation préalable obligatoire juste avant une première utilisation.  When a user wishes to apply the mascara 14 on her eyelashes, she grasps the gripping member 36, unscrews the cap 24 and extracts the stem 26 of the container 12 without prior mandatory agitation just before a first use.
La tige 26 solidaire du bouchon 24 est alors entraînée au moins en translation par rapport au récipient 12.  The rod 26 secured to the plug 24 is then driven at least in translation relative to the container 12.
Comme illustré sur la Figure 2, le mouvement de translation et aussi ici de rotation de la tige 26 libère une partie des particules solides 52 qui se sont accumulées au niveau de l'aimant 44, en générant un « vortex » de particules solides 52 qui tourbillonnent sensiblement autour de l'axe Z au voisinage de la tige 26 et donc à proximité de la tête applicatrice 28 lors de l'extraction de 1 ' applicateur 16 hors du récipient 12. As illustrated in FIG. 2, the translational and also rotational movement of the rod 26 releases a part of the solid particles 52 which have accumulated at the level of the magnet 44, generating a "vortex" of solid particles 52 which substantially swirl around the Z axis in the vicinity of the rod 26 and therefore to near the applicator head 28 during the extraction of the applicator 16 from the container 12.
Les propriétés magnétiques de l'aimant 44 peuvent donc être également choisies de façon à ce qu'un déplacement de la tige 26 par rapport au récipient 12 entraîne la libération des particules solides 52 attirées sur la tige 26. Cette possibilité est particulièrement adaptée lorsque le récipient et la composition sont transparents et/ou translucides afin de créer des effets visuels dans le récipient 12.  The magnetic properties of the magnet 44 can therefore also be chosen so that a displacement of the rod 26 relative to the container 12 causes the release of the solid particles 52 attracted to the rod 26. This possibility is particularly suitable when the container and composition are transparent and / or translucent to create visual effects in the container 12.
Lorsque le bouchon 24 est complètement dévissé du récipient 12, l'utilisatrice poursuit le mouvement d'extraction de 1 ' applicateur 16 hors du récipient 12 en déplaçant 1 ' applicateur 16 selon l'axe Z.  When the cap 24 is completely unscrewed from the container 12, the user continues the extraction movement of the applicator 16 from the container 12 by moving the applicator 16 along the axis Z.
Le passage de la tige 26 à travers l'organe de nettoyage 40 libère les particules solides 52 qui se sont accumulées au niveau de l'aimant 44 et qui n'ont pas été libérées par la rotation de la tige 26. Ces particules solides 52 tombent alors dans la phase liquide 48 du mascara 14 sous forme de pluie de particules solides 52 (Figure 3 ) .  The passage of the rod 26 through the cleaning member 40 releases the solid particles 52 which have accumulated at the level of the magnet 44 and which have not been released by the rotation of the rod 26. These solid particles 52 then fall into the liquid phase 48 of mascara 14 in the form of rain of solid particles 52 (Figure 3).
L'ensemble des particules solides 52 qui se sont agglomérées sur la tige 26 au niveau de l'aimant 44 sont ainsi dispersées dans la phase liquide 48 du mascara 14 au voisinage de la tige 26 et de la tête applicatrice 28, et forment ainsi momentanément dans la phase liquide 48 une phase dont la viscosité est sensiblement augmentée du fait de la présence d'une quantité importante de particules solides 52.  All of the solid particles 52 which have agglomerated on the rod 26 at the level of the magnet 44 are thus dispersed in the liquid phase 48 of the mascara 14 in the vicinity of the rod 26 and the applicator head 28, and thus form momentarily in the liquid phase 48 a phase whose viscosity is substantially increased due to the presence of a large quantity of solid particles 52.
La tête applicatrice 28 traverse alors ce nuage de particules solides 52 et se charge du mascara 14 qui vient d'être homogénéisé et qui peut ainsi être appliqué par l'utilisatrice sur ses cils (Figure 4). L'utilisatrice vient en quelque sorte d'ajuster temporairement au voisinage de la tête applicatrice 28 la viscosité de la composition liquide 14 afin d'en optimiser le chargement sur la tête applicatrice 28 avec une quantité optimale et reproductible de particules solides 52. The applicator head 28 then passes through this cloud of solid particles 52 and takes charge of the mascara 14 which has just been homogenized and which can thus be applied by the user to her eyelashes (FIG. 4). The user is in a way to adjust temporarily to the vicinity of the applicator head 28 the viscosity of the liquid composition 14 to optimize loading on the applicator head 28 with an optimal and reproducible amount of solid particles 52.
Grâce à ces dispositions, on garantit un prélèvement optimal de particules solides 52 à chaque utilisation, ce qui permet d'obtenir un effet esthétique plus homogène dans le temps et préserve le potentiel d'application de la composition restante en limitant sa dégradation, contrairement aux dispositifs de l'art antérieur dans lesquels la concentration en particules solides augmente lorsqu'on prélève à chaque utilisation trop de composition liquide et pas assez de particules solides qui au final sont perdues.  Thanks to these provisions, an optimal collection of solid particles 52 is guaranteed at each use, which makes it possible to obtain a more homogeneous aesthetic effect over time and preserves the application potential of the remaining composition by limiting its degradation, unlike the devices of the prior art in which the concentration of solid particles increases when each use is taken too much liquid composition and not enough solid particles which ultimately are lost.
Une fois l'application terminée, l'utilisatrice insère la tête applicatrice 28 et la tige 26 dans le récipient et visse le bouchon 24 sur le col 20.  Once the application is completed, the user inserts the applicator head 28 and the rod 26 into the container and screws the stopper 24 onto the neck 20.
Une partie des particules solides 52 toujours en suspension dans la phase liquide est attirée par l'aimant 44 et s'agglomère alors sur la tige 26, tandis que le reste des particules solides 52 tombe au fond du récipient 12. Le dispositif 10 se retrouve dans la position de repos illustrée sur la Figure 1 avec une quantité moindre de mascara 14.  Part of the solid particles 52 still suspended in the liquid phase is attracted by the magnet 44 and then agglomerates on the rod 26, while the rest of the solid particles 52 fall to the bottom of the container 12. The device 10 is found in the rest position shown in Figure 1 with a lesser amount of mascara 14.
Le dispositif 10 peut être commercialisé seul ou faire partie d'un kit de maquillage pour les cils. Un tel kit peut ainsi comprendre un premier dispositif d'application et de conditionnement d'un premier mascara servant notamment de base de mascara (« base coat ») , et d'un second dispositif de conditionnement et d'application selon l'invention contenant un second mascara servant notamment de finition de mascara (« top coat ») .  The device 10 may be marketed alone or be part of a makeup kit for eyelashes. Such a kit may thus comprise a first device for applying and conditioning a first mascara serving in particular as mascara base ("base coat"), and a second device for packaging and application according to the invention containing a second mascara used for finishing mascara ("top coat").
La Figure 5 illustre un dispositif 110 de conditionnement et d'application d'une composition liquide selon un deuxième mode de réalisation de l'invention.  Figure 5 illustrates a device 110 for packaging and applying a liquid composition according to a second embodiment of the invention.
Ce deuxième mode de réalisation de l'invention diffère du premier mode de réalisation des Figures 1 à 4 en ce que la partie magnétique 142 de la tige 126 comprend trois aimants identiques les uns aux autres, dont un aimant central 144 disposé sur le tronçon central 147 de la zone 146 de la tige 126, et deux aimants d'extrémité 144', 144'' disposés de part et d'autre de l'aimant central 144 et sensiblement à équidistance de l'aimant central 144. On considère alors que la partie magnétique 142 s'étend sur toute la zone 146 de la tige 126 de manière discontinue. This second embodiment of the invention differs from the first embodiment of Figures 1 to 4 in that the magnetic portion 142 of the rod 126 comprises three magnets identical to each other, including a central magnet 144 disposed on the central portion 147 of the zone 146 of the rod 126 , and two end magnets 144 ', 144''disposed on either side of the central magnet 144 and substantially equidistant from the central magnet 144. It is then considered that the magnetic portion 142 extends over any the zone 146 of the rod 126 in a discontinuous manner.
Les particules solides 152 sont donc accumulées sur la tige 126 en trois emplacements différents, permettant ainsi de créer un motif à l'intérieur du récipient 112 lorsque le dispositif 110 est en position de repos.  The solid particles 152 are thus accumulated on the rod 126 in three different locations, thus creating a pattern inside the container 112 when the device 110 is in the rest position.
La phase liquide 148 du mascara 114 et le corps 118 du récipient 112 étant transparents et/ou translucides, ce motif est visible par l'utilisatrice.  The liquid phase 148 of the mascara 114 and the body 118 of the container 112 being transparent and / or translucent, this pattern is visible to the user.
Les particules solides 152 sont donc toujours visibles par l'utilisatrice, qu'elles soient à l'intérieur du récipient 112 ou sur ses cils.  The solid particles 152 are always visible to the user, whether they are inside the container 112 or on her eyelashes.
En variante, la partie magnétique 142 comprend un nombre différent d'aimants, par exemple deux, quatre ou plus, qui peuvent être disposés les uns par rapport aux autres de manière quelconque le long de la zone 146 de la tige 126.  Alternatively, the magnetic portion 142 comprises a different number of magnets, for example two, four or more, which may be arranged relative to one another in any way along the zone 146 of the rod 126.
La Figure 6 illustre un dispositif 210 de conditionnement et d'application d'une composition liquide selon un troisième mode de réalisation de l'invention.  Figure 6 illustrates a device 210 for packaging and applying a liquid composition according to a third embodiment of the invention.
Ce troisième mode de réalisation de l'invention diffère du deuxième mode de réalisation de la Figure 5 en ce que les trois aimants 244, 244 ', 244 '' présentent des forces d'aimantation différentes les unes des autres. Ici, la force d'aimantation de l'aimant distal 244'' est supérieure à celle de l'aimant central 244 qui est elle- même supérieure à celle de l'aimant proximal 244', créant ainsi un gradient de champ magnétique orienté le long de l'axe longitudinal Z de la tige 226 vers son extrémité distale 238b. This third embodiment of the invention differs from the second embodiment of Figure 5 in that the three magnets 244, 244 ', 244''have different magnetization forces from each other. Here, the magnetization force of the distal magnet 244 '' is greater than that of the central magnet 244 which is itself greater than that of the proximal magnet 244 ', thereby creating a magnetic field gradient oriented on the along the longitudinal axis Z of the rod 226 towards its distal end 238b.
En variante, un gradient de champ magnétique peut également être créé avec des aimants de tailles différentes. On peut aussi jouer sur les lignes de champ magnétique pour créer des motifs.  Alternatively, a magnetic field gradient can also be created with magnets of different sizes. You can also play on magnetic field lines to create patterns.
En fonction du nombre d'aimants, de leur taille, de leur position sur la tige, de leur force d'aimantation et de l'orientation de chaque champ magnétique, les particules solides vont s'accumuler sur la tige de façon différente d'un dispositif à un autre. Il est ainsi possible de créer un très grand nombre de motifs différents pour le dispositif .  Depending on the number of magnets, their size, their position on the rod, their magnetization force and the orientation of each magnetic field, the solid particles will accumulate on the stem in a different way from one device to another. It is thus possible to create a very large number of different patterns for the device.
Dans un quatrième mode de réalisation de l'invention, la partie magnétique est constituée par des particules magnétiques ou magnétisables intégrées au matériau constitutif de la tige. Par exemple, la tige peut être réalisée à l'aide d'un aimant de type « terre rare », par exemple le néodyme, ou en matière plastique magnétisable, la matière plastique s 'aimantant dans le moule de transformation, et surmoulée d'une peau de protection jouant un rôle barrière entre la composition liquide et la tige.  In a fourth embodiment of the invention, the magnetic part is constituted by magnetic or magnetizable particles integrated in the material constituting the rod. For example, the rod can be made using a rare earth type magnet, for example neodymium, or magnetizable plastic material, the plastic material magnetized in the transformation mold, and overmolded a protective skin acting as a barrier between the liquid composition and the stem.
Ces particules peuvent être localisées en un ou plusieurs endroits prédéterminés de la zone de la tige, par exemple au niveau de son tronçon central et/ou de ses extrémités, et présenter des concentrations différentes d'un endroit de la zone de la tige à un autre.  These particles may be located at one or more predetermined locations in the area of the stem, for example at its central section and / or at its ends, and may have different concentrations from one location in the stem area to one other.
En variante, les particules peuvent être distribuées sur toute la longueur de la zone de la tige, de manière homogène c'est-à-dire avec une concentration sensiblement constante le long de la zone de la tige, ou inhomogène c'est-à-dire avec une concentration variable le long de la zone de la tige. On considère alors que la partie magnétique s'étend sensiblement sur toute la longueur de la zone de la tige de manière continue. Alternatively, the particles may be distributed over the entire length of the zone of the stem, homogeneously that is to say with a substantially constant concentration along the area of the stem, or inhomogeneous that is to say say with a variable concentration along the area of the stem. It is then considered that the magnetic part extends substantially over the entire length of the rod area continuously.
Il est ainsi possible de créer un grand nombre de motifs différents pour le dispositif en fonction de la position des particules magnétiques ou magnétisables formant la tige et/ou de leur concentration.  It is thus possible to create a large number of different patterns for the device depending on the position of the magnetic or magnetizable particles forming the rod and / or their concentration.
La tige est par exemple obtenue par injection ou par bi-injection de matière plastique chargée en particules aimantées .  The rod is for example obtained by injection or by bi-injection of plastic material loaded with magnetic particles.
Dans un cinquième mode de réalisation de l'invention, la tête applicatrice comprend également une partie magnétique apte à attirer les particules solides de la composition cosmétique. Par exemple, la tête applicatrice peut comprendre un aimant. En variante, la tête applicatrice comprend un embout métallique recouvert d'un flocage et relié par un fil métallique à un aimant central disposé dans la tige.  In a fifth embodiment of the invention, the applicator head also comprises a magnetic part capable of attracting the solid particles of the cosmetic composition. For example, the applicator head may comprise a magnet. Alternatively, the applicator head comprises a metal tip covered with a flocking and connected by a wire to a central magnet disposed in the rod.
L'invention propose donc un dispositif de conditionnement et d'application d'une composition liquide, notamment cosmétique, qui est simple à utiliser et dont le résultat d'application de la composition est satisfaisant et procure l'effet visuel souhaité.  The invention therefore proposes a device for packaging and applying a liquid composition, in particular a cosmetic composition, which is simple to use and whose application result of the composition is satisfactory and provides the desired visual effect.
En effet, le simple dévissage du bouchon combiné à l'extraction de la tige à travers l'organe de nettoyage permet de modifier localement et momentanément la viscosité de la composition cosmétique pour mieux charger la tête applicatrice en particules solides sans avoir à mettre en œuvre obligatoirement une étape d'agitation comme celles connues de l'art antérieur et qui sont néfastes. La gestuelle habituelle de l'utilisatrice pour un mascara s'en trouve ainsi changée.  Indeed, the simple unscrewing of the plug combined with the extraction of the rod through the cleaning member makes it possible locally and momentarily to modify the viscosity of the cosmetic composition in order to better load the applicator head with solid particles without having to implement necessarily a stirring step as those known from the prior art and which are harmful. The usual gesture of the user for a mascara is thus changed.
En particulier, avec le dispositif selon l'invention, il n'est pas nécessaire d'agiter le récipient ni de « pistonner », c'est-à-dire d'effectuer des mouvements de va-et-vient avec 1 ' applicateur , pour homogénéiser la composition cosmétique juste avant son application. Ceci permet non seulement de simplifier l'utilisation du dispositif, mais également de prolonger la durée de vie de la composition cosmétique en limitant l'introduction d'air à l'intérieur du récipient, limitant de ce fait le dessèchement de la composition cosmétique au cours du temps, qui constitue un problème majeur pour toute composition cosmétique et tout particulièrement un mascara. In particular, with the device according to the invention, it is not necessary to stir the container or to "pump", that is to say, to perform back-and-forth movements with the applicator to homogenize the cosmetic composition just before its application. This not only simplifies the use of the device, but also extends the life of the cosmetic composition by limiting the introduction of air into the container, thereby limiting the drying of the cosmetic composition to course of time, which is a major problem for any cosmetic composition and especially a mascara.
De plus, en limitant le dessèchement de la composition cosmétique, on limite non seulement la perte de produit mais on limite également l'encrassement de la tête applicatrice . En effet, selon l'invention, le produit plus visqueux restant après application retourne dans une phase liquide nettement moins visqueuse et en quantité nettement plus importante, ce qui permet au produit de revenir à une valeur de viscosité plus faible et donc d'une certaine façon de « nettoyer » la tête applicatrice. On dispose ainsi d'une tête applicatrice dont les propriétés ne se dégradent pas ou alors nettement moins rapidement car on remet le dispositif dans un état initial après chaque utilisation grâce à la mobilité des particules solides.  In addition, by limiting the drying of the cosmetic composition, not only the loss of product is limited but also the fouling of the applicator head. Indeed, according to the invention, the more viscous product remaining after application returns to a much less viscous liquid phase and in a much larger quantity, which allows the product to return to a lower viscosity value and therefore a certain how to "clean" the applicator head. This provides an applicator head whose properties do not degrade or much less quickly because the device is returned to an initial state after each use through the mobility of solid particles.
Grâce au dispositif selon l'invention, il est en outre possible de supprimer les épaississants devenus inutiles. Or ces épaississants, comme les cires en particulier, confèrent à la composition de la matité. Il est donc possible avec l'invention de s'affranchir de ce problème et d'avoir une composition brillante. Cela joue un rôle important avec les compositions colorées ainsi que pour le rendu des effets optiques comme les phénomènes de réflexion/réfraction engendrés par certaines particules solides comme les nacres.  Thanks to the device according to the invention, it is also possible to remove thickeners become useless. These thickeners, like waxes in particular, confer on the composition of dullness. It is therefore possible with the invention to overcome this problem and to have a brilliant composition. This plays an important role with the colored compositions as well as for the rendering of the optical effects such as the reflection / refraction phenomena generated by certain solid particles such as nacres.
Par ailleurs, la composition cosmétique présentant une phase liquide, le dispositif selon l'invention permet non seulement d'appliquer la composition cosmétique de manière optimale, notamment sous forme de film, mais également de rendre visibles les particules solides, créant ainsi un aspect et un effet visuel satisfaisants. Furthermore, since the cosmetic composition has a liquid phase, the device according to the invention makes it possible not only to apply the cosmetic composition optimally, especially in the form of a film, but also to make the solid particles visible, creating thus a satisfactory appearance and visual effect.
De plus, le dispositif présente au repos une esthétique surprenante et agréable qui peut être modulée en fonction de la composition, de la position et des propriétés magnétiques de la partie magnétique.  In addition, the device has at rest a surprising and pleasant aesthetic that can be modulated according to the composition, position and magnetic properties of the magnetic part.
L'invention a été décrite en se référant à du mascara comme composition cosmétique et aux cils comme application, mais il est tout à fait possible d'utiliser l'invention pour d'autres applications, par exemple un mascara pour cheveux et plus généralement toutes fibres kératiniques , un vernis à ongles, un rouge à lèvres liquide, un gloss, etc.  The invention has been described with reference to mascara as a cosmetic composition and eyelashes as an application, but it is quite possible to use the invention for other applications, for example a mascara for hair and more generally all keratinous fibers, a nail polish, a liquid lipstick, a gloss, etc.
