Description

La présente invention concerne un ensemble applicateur pour un produit fluide, notamment un produit cosmétique.The present invention relates to an applicator assembly for a fluid product, in particular a cosmetic product.

Le produit fluide peut être sous forme liquide ou sous forme de crème ou de pâte plus ou moins visqueuse. Le produit fluide est, par exemple, un mascara ou un "eye-liner".The fluid product can be in liquid form or in the form of a more or less viscous cream or paste. The fluid product is, for example, a mascara or an "eyeliner".

Les ensembles applicateurs de ce type sont, de façon connue, constitués par un flacon muni d'un goulot, par un capuchon qui vient se fixer, le plus souvent par vissage, sur le goulot pour fermer le flacon et d'un applicateur fixé sur une tige qui est solidaire du capuchon. Ces ensembles comportent également, de façon connue, un essoreur qui est muni d'une lèvre de raclage, généralement souple, qui est fixé sur le goulot du flacon et qui est destiné à éliminer, lors du prélèvement du produit, l'excès de produit sur l'applicateur ; l'applicateur a le plus souvent en section, sur une partie de sa longueur, des dimensions supérieures à celles de la tige. Dans ces ensembles, en position de stockage, lorsque le capuchon est fixé sur le flacon, l'applicateur est plongé dans le produit et la tige portant l'applicateur traverse l'essoreur. Quand on retire le capuchon pour prélever le produit, l'applicateur passe à travers l'essoreur et la lèvre de l'essoreur râcle l'applicateur, ce qui élimine l'excès de produit sur l'applicateur.Applicator assemblies of this type are, in known manner, constituted by a bottle provided with a neck, by a cap which is fixed, most often by screwing, on the neck to close the bottle and by an applicator fixed on a rod which is integral with the cap. These assemblies also comprise, in known manner, a wringer which is provided with a scraping lip, generally flexible, which is fixed to the neck of the bottle and which is intended to remove, during the withdrawal of the product, the excess product on the applicator; the applicator most often has in section, over a part of its length, dimensions greater than those of the rod. In these assemblies, in the storage position, when the cap is fixed to the bottle, the applicator is immersed in the product and the rod carrying the applicator passes through the wiper. When the cap is removed to withdraw the product, the applicator passes through the wiper and the wiper lip scrapes the applicator, which eliminates the excess product on the applicator.

Mais ce type d'ensemble applicateur présente un inconvénient. La lèvre de l'essoreur ménage, en général, une ouverture dont la section est voisine de celle de la section transversale de la tige portant l'applicateur, ce qui est nécessaire pour assurer l'étanchéité de l'ensemble. Dans ces conditions, la tige agit comme un piston et il se crée une dépression dans le flacon lorsqu'on retire la tige. Lorsque l'applicateur passe à travers l'essoreur, le produit essoré est aspiré sous l'effet de la dépression et vient se déposer à l'extrémité de l'applicateur. Il se forme ainsi à l'extrémité de l'applicateur une goutte, ou un amas de produit, gênant le maquillage et ayant tendance à encrasser l'applicateur.However, this type of applicator assembly has a drawback. The wiper lip generally cleans an opening, the cross section of which is close to that of the cross section of the rod carrying the applicator, which is necessary for sealing the assembly. Under these conditions, the rod acts like a piston and a vacuum is created in the bottle when the rod is removed. When the applicator passes through the wiper, the wrung product is sucked under the effect of the vacuum and is deposited at the end of the applicator. There is thus formed at the end of the applicator a drop, or a heap of product, interfering with the makeup and having a tendency to clog the applicator.

La présente invention concerne un ensemble applicateur qui remédie à cet inconvénient.The present invention relates to an applicator assembly which overcomes this drawback.

La présente invention a pour objet un ensemble applicateur d'un produit fluide, notamment un produit cosmétique, comprenant un flacon, un capuchon pour fermer ledit flacon, un applicateur disposé à l'extrémité d'une tige solidaire du capuchon et un essoreur muni d'une lèvre, l'applicateur étant entièrement plongé dans le flacon et la tige traversant l'essoreur lorsque le capuchon est fixé, et l'applicateur passant entièrement à travers l'essoreur lorsque le capuchon est séparé du flacon lors du prélèvement du produit, caractérisé par le fait que la lèvre de l'essoreur est au moins partiellement floquée à l'aide de fibres de flocage.The subject of the present invention is an applicator assembly for a fluid product, in particular a cosmetic product, comprising a bottle, a cap for closing said bottle, an applicator disposed at the end of a rod secured to the cap and a wringer provided with a lip, the applicator being entirely immersed in the bottle and the rod passing through the wiper when the cap is attached, and the applicator passing entirely through the wiper when the cap is separated from the bottle when the product is withdrawn, characterized in that the wiper lip is at least partially flocked using flocking fibers.

En effet, on a trouvé que la présence de fibres de flocage sur la lèvre de l'essoreur permet d'obtenir une rentrée d'air dans le flacon suffisante pour qu'il n'y ait plus formation d'une dépression lorsqu'on retire la tige portant l'applicateur, tout en préservant une étanchéité suffisante vis-à-vis du produit contenu dans le flacon. Il ne se forme pratiquement plus de goutte, ou d'amas de produit, à l'extrémité de l'applicateur et, si elle se forme, les fibres de flocage se referment comme un diaphragme après le passage de l'applicateur, et coupent et/ou absorbent l'excès de produit à l'extrémité de l'applicateur. Par ailleurs, on a constaté que la tige reste plus propre qu'en l'absence de fibres de flocage. De plus, on a constaté que la présence de fibres de flocage ne modifie pas la quantité efficace de produit restant sur l'applicateur.Indeed, it has been found that the presence of flocking fibers on the wringer of the wiper makes it possible to obtain a sufficient return of air into the bottle so that there is no longer the formation of a depression when removes the rod carrying the applicator, while preserving a sufficient seal against the product contained in the bottle. There is practically no more drop or clump of product at the end of the applicator and, if it forms, the flocking fibers close like a diaphragm after the passage of the applicator, and cut and / or absorb the excess product at the end of the applicator. Furthermore, it has been found that the rod remains cleaner than in the absence of flocking fibers. In addition, it has been found that the presence of flocking fibers does not modify the effective amount of product remaining on the applicator.

Le flocage est effectué de façon connue en enduisant, au moins partiellement, la lèvre de l'essoreur à l'aide d'une colle ou adhésif liquide, par pulvérisation ou par trempage, puis en faisant passer l'essoreur enduit de colle dans un lit de fibres de flocage maintenues en suspension. Les fibres se déposent sur la surface enduite par attraction électrostatique et, dans la majorité des cas, les fibres s'orientent pratiquement perpendiculairement à la surface enduite. Les fibres de flocage peuvent être, avantageusement, en nylon, en coton, en polyester, en rayonne. Leur longueur est, généralement, comprise entre 0,2 et 2 mm.The flocking is carried out in a known manner by coating, at least partially, the lip of the wringer with a glue or liquid adhesive, by spraying or by dipping, then by passing the wringer wrinkled with glue in a bed of flocking fibers kept in suspension. The fibers are deposited on the coated surface by electrostatic attraction and, in the majority of cases, the fibers orient themselves practically perpendicular to the coated surface. The flocking fibers can advantageously be made of nylon, cotton, polyester, rayon. Their length is generally between 0.2 and 2 mm.

Dans l'ensemble applicateur selon l'invention, la tige a en section, de préférence, des dimensions inférieures aux dimensions de l'ouverture de l'essoreur, c'est-à-dire des dimensions inférieures à celles nécessaires pour que la tige ait juste le jeu nécessaire pour traverser l'essoreur. Les fibres de flocage ont donc, de préférence, au moins la longueur nécessaire pour combler l'espace entre la lèvre de l'essoreur et la tige. Par exemple, lorsque l'ouverture de la lèvre est circulaire et que la tige est cylindrique, les fibres de flocage ont avantageusement au moins une longueur égale à la différence entre le rayon de l'ouverture et le rayon de la section de la tige. Les fibres peuvent cependant avoir une longueur supérieure, voire très supérieure, notamment en fonction de l'extrémité de l'applicateur d'où l'excès de produit doit être retiré.In the applicator assembly according to the invention, the rod preferably has a cross section of dimensions smaller than the dimensions of the wiper opening, that is to say dimensions less than those necessary so that the rod has just the clearance necessary to pass through the wiper. The flocking fibers therefore preferably have at least the length necessary to fill the space between the wiper lip and the rod. For example, when the opening of the lip is circular and the rod is cylindrical, the flocking fibers advantageously have at least a length equal to the difference between the radius of the opening and the radius of the section of the rod. The fibers may, however, have a longer, or even much longer, length, in particular depending on the end of the applicator from which the excess product must be removed.

Selon un mode de réalisation préféré, la tige portant l'applicateur comporte un rétreint disposé au niveau de la lèvre de l'essoreur lorsque le capuchon est fixé, c'est-à-dire en position de stockage. On évite ainsi que la tige ne tasse, pendant le stockage, les fibres de flocage lorsque celles-ci ont une longueur très supérieure à celle juste nécessaire pour combler l'espace entre la lèvre de l'essoreur et la tige en dehors du rétreint.According to a preferred embodiment, the rod carrying the applicator comprises a constriction disposed at the level of the wiper lip when the cap is fixed, that is to say in the storage position. This avoids that the rod does not cup, during storage, the flocking fibers when these have a length much greater than that just necessary to fill the space between the wiper lip and the rod outside the neck.

Il faut noter qu'un avantage de la présente invention est de permettre de modifier la longueur des fibres de flocage pour ajuster un essoreur donné à un applicateur donné, muni d'une tige donnée. En d'autres termes, un même essoreur peut être adapté à plusieurs types d'applicateurs en modifiant simplement la longueur des fibres de flocage, ce qui est intéressant d'un point de vue industriel.It should be noted that an advantage of the present invention is that it makes it possible to modify the length of the flocking fibers to adjust a given wringer to a given applicator, provided with a given rod. In other words, the same wringer can be adapted to several types of applicators by simply modifying the length of the flocking fibers, which is advantageous from an industrial point of view.

L'essoreur utilisé selon l'invention peut avoir toute forme connue dans ce type d'ensemble applicateur, notamment dans les ensembles applicateurs pour mascara. L'ouverture formée par la lèvre de l'essoreur peut être par exemple circulaire, ovale ou carrée ; elle peut également être en étoile. L'essoreur peut comporter une jupe, ou ne pas comporter de jupe. S'il comporte une jupe, celle-ci peut être fendue, pour donner plus de souplesse. L'essoreur peut comporter deux étages, les deux étages faisant partie d'une seule pièce ou de deux pièces différentes. Dans les essoreurs à deux étages, de préférence, seul le premier étage, c'est-à-dire celui le plus éloigné du capuchon, est pourvu d'un flocage selon l'invention.The wiper used according to the invention may have any form known in this type of applicator assembly, in particular in applicator assemblies for mascara. The opening formed by the wiper lip can be for example circular, oval or square; it can also be a star. The wringer may have a skirt, or may not have a skirt. If it has a skirt, it can be split, to give more flexibility. The wringer can have two stages, the two stages being part of a single part or of two different parts. In two-stage wipers, preferably only the first stage, that is to say the one furthest from the cap, is provided with flocking according to the invention.

L'ouverture de la lèvre de l'essoreur, dans le cas des applicateurs pour produits cosmétiques, a généralement une dimension maximale en section pouvant varier entre 2 mm et 15 mm.The opening of the wiper lip, in the case of applicators for cosmetic products, generally has a maximum dimension in section which can vary between 2 mm and 15 mm.

L'essoreur peut, de façon connue, être moulé en matière thermoplastique dure ou semi-souple ou en élastomère.The wiper can, in known manner, be molded from hard or semi-flexible thermoplastic material or from elastomer.

L'applicateur peut être tout applicateur connu dans ce type d'ensemble applicateur. Il peut être, par exemple, constitué d'une brosse, d'un pinceau, d'une pointe, en particulier conique, en mousse plastique ou en feutre capillaire ou d'une pointe munie de flocage.The applicator can be any known applicator in this type of applicator assembly. It can be, for example, made up of a brush, a paint brush, a point, in particular conical, made of plastic foam or capillary felt or a point provided with flocking.

L'ensemble applicateur représenté sur la figure 1 est désigné dans son ensemble par la référence 1. Il est constitué par un flacon 2, un capuchon 3 fixé sur le flacon 2, un applicateur 4 porté par une tige 5 solidaire du capuchon 3 et par un essoreur 6.The applicator assembly shown in FIG. 1 is generally designated by the reference 1. It consists of a bottle 2, a cap 3 fixed on the bottle 2, an applicator 4 carried by a rod 5 secured to the cap 3 and by a wringer 6.

Le flacon 2 est constitué d'un corps cylindrique 21 relié à un goulot 22 de plus faible diamètre par un épaulement 23. Le goulot 22 est muni extérieurement d'un filet 24.The bottle 2 consists of a cylindrical body 21 connected to a neck 22 of smaller diameter by a shoulder 23. The neck 22 is externally provided with a thread 24.

Le capuchon 3 comporte un fond plat 31 circulaire et une jupe cylindrique 32 à section circulaire munie sur sa face intérieure d'un filet 33 susceptible de coopérer avec le filet 24 du goulot 22.The cap 3 comprises a circular flat bottom 31 and a cylindrical skirt 32 of circular section provided on its inner face with a thread 33 capable of cooperating with the thread 24 of the neck 22.

L'applicateur 4 est, par exemple, une brosse spirale de forme générale conique. Ladite brosse est fixée sur la tige 5. Cette tige 5 se termine par une jupe de fixation cylindrique 51 dont le diamètre externe est égal, au jeu nécessaire près, au diamètre interne de la jupe 32. La jupe 51 est montée à force dans le capuchon 3. La tige 5 est constituée par un élément cylindrique 52 muni d'un rétreint de plus faible diamètre 53 disposé de façon qu'en position de stockage, c'est-à-dire lorsque le couvercle 3 est vissé sur le flacon 2, ledit rétreint 53 se trouve au niveau de la lèvre de l'essoreur 6.The applicator 4 is, for example, a spiral brush of generally conical shape. Said brush is fixed on the rod 5. This rod 5 ends in a cylindrical fixing skirt 51 whose external diameter is equal, apart from the necessary clearance, to the internal diameter of the skirt 32. The skirt 51 is forcibly mounted in the cap 3. The rod 5 is constituted by a cylindrical element 52 provided with a constriction of smaller diameter 53 arranged so that in the storage position, that is to say say when the cover 3 is screwed onto the bottle 2, said constriction 53 is located at the level of the wiper 6.

L'essoreur 6 représenté sur la figure 1 est du type à jupe. Il comporte un premier élément cylindrique 61 de diamètre extérieur égal, au jeu nécessaire près pour son montage, au diamètre interne du goulot. Ledit élément 61 est muni à une extrémité d'une collerette externe de retenue 62 qui vient reposer sur le bord libre du goulot 22 et à son autre extrémité d'une jupe cylindrique 63 formant la lèvre de l'essoreur 6. Cette lèvre 63 est partiellement recouverte de fibres de flocage 64, ces fibres étant fixées sur le bord et sur une certaine hauteur des surfaces externe et interne de la lèvre 63.The wiper 6 shown in Figure 1 is of the skirt type. It comprises a first cylindrical element 61 with an external diameter equal, apart from the clearance necessary for its assembly, to the internal diameter of the neck. Said element 61 is provided at one end with an external retaining flange 62 which comes to rest on the free edge of the neck 22 and at its other end with a cylindrical skirt 63 forming the lip of the wiper 6. This lip 63 is partially covered with flocking fibers 64, these fibers being fixed on the edge and on a certain height of the external and internal surfaces of the lip 63.

En position de stockage (comme représenté sur la figure 1), le capuchon 3 est vissé sur le goulot 22 du flacon 2. L'applicateur 4 est contenu dans le corps 21 du flacon 2 et plonge dans le produit à appliquer ; le rétreint 53 de l'élément cylindrique 52 de la tige 5 est disposé au niveau de la lèvre 63 de l'essoreur 6.In the storage position (as shown in FIG. 1), the cap 3 is screwed onto the neck 22 of the bottle 2. The applicator 4 is contained in the body 21 of the bottle 2 and is immersed in the product to be applied; the constriction 53 of the cylindrical element 52 of the rod 5 is disposed at the level of the lip 63 of the wiper 6.

Lorsque l'utilisateur désire prélever du produit, il dévisse le capuchon 3 et tire sur la tige 5 portant l'applicateur 4. L'élément cylindrique 52 passe dans la lèvre 63 de l'essoreur 6 où elle est en contact avec les fibres de flocage 64. La présence des fibres de flocage 64 entre l'élément cylindrique 52 et la lèvre 63 de l'essoreur 6 permet à l'air de pénétrer dans le flacon 2 et il ne se forme pas de dépression. L'applicateur 4 passe ensuite à travers la lèvre 63 de l'essoreur 6. La lèvre 63 de l'essoreur élimine l'excès de produit chargé sur l'applicateur 4. L'utilisateur peut alors procéder à l'application du produit. Après application, l'utilisateur rentre l'applicateur dans le flacon 2 et visse le capuchon 3. L'ensemble applicateur est prêt pour un nouvel usage.When the user wishes to withdraw product, he unscrews the cap 3 and pulls on the rod 5 carrying the applicator 4. The cylindrical element 52 passes through the lip 63 of the wiper 6 where it is in contact with the fibers of flocking 64. The presence of the flocking fibers 64 between the cylindrical element 52 and the lip 63 of the wiper 6 allows air to enter the bottle 2 and there is no depression formed. The applicator 4 then passes through the lip 63 of the wiper 6. The lip 63 of the wiper eliminates the excess of product loaded on the applicator 4. The user can then proceed to apply the product. After application, the user returns the applicator to the bottle 2 and screws the cap 3. The applicator assembly is ready for new use.

La figure 2 représente un essoreur en étoile, désigné dans son ensemble par 106. L'essoreur est constitué par un élément cylindrique 161 portant une collerette externe de retenue 162. La lèvre 163 de l'essoreur 106 est constituée par un fond bombé fermant l'élément 161 et découpé en étoile de façon à former des languettes, quatre dans l'exemple représenté. Des fibres de flocage 164 sont fixées, en partie, sur les faces externe et interne des languettes, et sur le bord de celles-ci.FIG. 2 represents a star wringer, designated as a whole by 106. The wringer is constituted by a cylindrical element 161 carrying an external retaining collar 162. The lip 163 of the wringer 106 is constituted by a convex bottom closing l element 161 and cut into a star so as to form tongues, four in the example shown. Flocking fibers 164 are fixed, in part, on the external and internal faces of the tongues, and on the edge of these.

La figure 3 représente un essoreur à jupe fendue qui est désigné dans son ensemble par 206. Cet essoreur comporte un élément cylindrique 261 muni à une extrémité d'une collerette externe de retenue 262 et à l'autre extrémité d'une lèvre d'essorage 263. Cette lèvre 263 est constituée par une jupe conique munie de deux fentes longitudinales 265 diamètralement opposées s'étendant sur la majeure partie de sa hauteur. Des fibres de flocage 264 sont déposées sur le bord et sur une partie des surfaces externe et interne de la lèvre 263.FIG. 3 represents a wringer with a split skirt which is generally designated by 206. This wringer comprises a cylindrical element 261 provided at one end with an external retaining flange 262 and at the other end with a wringing lip 263. This lip 263 is constituted by a conical skirt provided with two diametrically opposite longitudinal slots 265 extending over most of its height. Flocking fibers 264 are deposited on the edge and on part of the external and internal surfaces of the lip 263.

Les figures 4A et 4B représentent respectivement un flacon 302a, 302b sur le goulot duquel est monté un essoreur 306a, 306b ne comportant pas de jupe. Les lèvres 363a, 363b sont constituées par une collerette annulaire de section transversale triangulaire ménageant une ouverture 366a, 366b circulaire. Sur la figure 4A, qui correspond à l'art antérieur, on voit que l'ouverture 366a a un diamètre égal, au jeu nécessaire près, au diamètre de la tige 305a portant l'applicateur 304a. De cette façon, on évite les fuites du produit contenu dans le flacon pendant le stockage, mais, lorsqu'on tire la tige 305a lors du prélèvement de produit, il se forme une dépression dans le flacon 302a. Le produit essoré sur l'applicateur ne retombe pas dans le flacon mais est aspiré par la dépression et vient se déposer à l'extrémité de l'applicateur où il forme une goutte ou un amas gênant le maquillage.FIGS. 4A and 4B respectively represent a bottle 302 a , 302 b on the neck of which a wiper 306 a , 306 b is mounted, not comprising a skirt. The lips 363 a , 363 b consist of an annular collar of triangular cross section providing an opening 366 a , 366 b circular. In Figure 4A, which corresponds to the prior art, it is seen that the opening 366 has a diameter, for the necessary clearance, to the diameter of the rod 305 carrying the applicator 304 has a. In this way, it prevents leakage of the product contained in the bottle during storage but, when pulling the stem 305 has at the product removal, is formed a depression in the bottle 302. The product wrung out on the applicator does not fall back into the bottle but is sucked up by the vacuum and comes to settle at the end of the applicator where it forms a drop or a heap hindering make-up.

L'essoreur selon l'invention est représenté sur la figure 4B. Dans l'essoreur 306b selon l'invention, la lèvre 363b est munie de fibres de flocage 364 sur ses faces interne et externe et sur le bord. On voit sur cette figure que le diamètre de l'ouverture de la lèvre 366b est supérieur au diamètre de la tige et que les fibres déposées par flocage viennent remplir l'espace annulaire entre le bord de l'ouverture 366b et la tige 305b. On obtient ainsi un bon essorage de l'applicateur tout en laissant passer de l'air. Il ne se forme, par conséquent, plus de goutte ou d'amas de produit à la pointe de l'applicateur. La collerette annulaire formant la lèvre d'essorage 363b est également munie sur sa face tournée vers le flacon de fibres de flocage. Ces fibres ont l'avantage de freiner le retour du produit essoré vers l'ouverture de l'essoreur 306b et empêchent, par conséquent, le produit essoré de revenir sur l'applicateur 304b.The wiper according to the invention is shown in Figure 4B. In the wiper 306 b according to the invention, the lip 363 b is provided with flocking fibers 364 on its internal and external faces and on the edge. It can be seen in this figure that the diameter of the opening of the lip 366 b is greater than the diameter of the rod and that the fibers deposited by flocking fill the annular space between the edge of the opening 366 b and the rod 305 b . A good spin of the applicator is thus obtained while allowing air to pass through. There is therefore no longer a drop or heap of product at the tip of the applicator. The annular flange forming the wiping lip 363 b is also provided on its face facing the bottle of flocking fibers. These fibers have the advantage of slowing the return of the wrung product towards the opening of the wringer 306 b and consequently prevent the wrung product from returning to the applicator 304 b .

La figure 5 représente un essoreur 406 selon l'invention, comportant deux étages et constitué d'une seule pièce. Il est formé d'un élément cylindrique muni à une extrémité d'une collerette de retenue 462 tournée vers l'extérieur et à l'autre extrémité d'une collerette formant lèvre d'essorage 463 tournée vers l'intérieur ménageant une ouverture circulaire axiale 466. Les fibres de flocage 464 sont déposées sur les faces interne et externe et sur le bord de la lèvre d'essorage 463. A l'intérieur de l'élément 461 est disposée une seconde collerette 467 formant un second étage d'essorage. Cette seconde collerette 467 est dépourvue de fibre de flocageFIG. 5 represents a wiper 406 according to the invention, comprising two stages and consisting of a single piece. It is formed by a cylindrical element provided at one end with a retaining flange 462 facing outwards and at the other end with a flange forming a wiping lip 463 facing inwards providing an axial circular opening 466. The flocking fibers 464 are deposited on the internal and external faces and on the edge of the wiping lip 463. Inside the element 461 is disposed a second flange 467 forming a second wiping stage. This second flange 467 is devoid of flocking fiber

La figure 6 représente un essoreur 506 à deux étages qui est constitué de deux pièces : une première pièce constitue l'élément cylindrique 561 portant la collerette de retenue 562 tournée vers l'extérieur et la collerette interne 567 formant le second étage d'essorage. La seconde pièce forme la lèvre d'essorage 563. Elle est fixée à l'élément 561 par un système rainure-bourrelet et forme une collerette conique ménageant une ouverture axiale 566. Les faces externe et interne et le bord de la collerette 563 sont recouverts de fibres 564 par flocage.FIG. 6 represents a two-stage wiper 506 which consists of two parts: a first part constitutes the cylindrical element 561 carrying the retaining flange 562 facing outwards and the internal flange 567 forming the second wiping stage. The second part forms the wiping lip 563. It is fixed to the element 561 by a groove-bead system and forms a conical flange providing an axial opening 566. The external and internal faces and the edge of the flange 563 are covered 564 fibers by flocking.
