Abstract

The applicator has a protection cap which caps on an end of a tubular reservoir (1). The cap is formed of inner and outer caps, where the inner cap is fixed hermetically on an applicator nozzle (19). The reservoir has an elastic portion (2) that acts as atmospheric pump and that permits to forward a product to a brush (8) through the nozzle by pressing walls of the reservoir.

Description

La présente invention concerne un applicateur de produits liquides ouThe present invention relates to an applicator for liquid products or

visqueux constitué d'un pinceau solidaire d'un réservoir comportant des moyens pour alimenter, en produit, le faisceau de poils et l'empêcher de sécher, hors utilisation. viscous consisting of a brush integral with a reservoir having means for supplying, in product, the bundle of bristles and preventing it from drying, out of use.

Cette invention est particulièrement destinée à l'application des vernis à ongles, dans le 5 domaine cosmétique, mais elle peut aussi avoir une grande utilité dans le secteur domestique ou artistique, pour étendre colle ou peinture, par exemple. This invention is particularly intended for the application of nail polishes, in the cosmetic field, but it can also have great utility in the domestic or artistic sector, for example to extend glue or paint.

Il existe traditionnellement, sur le marché commercial, un type d'applicateur dont le but est semblable. Il est constitué d'un flacon sur lequel est vissé un capuchon muni d'une tige où est fixé un pinceau qui trempe en permanence dans le produit à appliquer. Ce système garantit le non séchage du faisceau de poils, quand l'applicateur n'est pas utilisé, mais présente trois inconvénients: nécessité de re-imbiber constamment le pinceau dans le flacon pour une utilisation continue, risque de chavirement du flacon et épaississement du produit à l'intérieur, par évaporation, quand on utilise le pinceau. Traditionally, there is a type of applicator on the commercial market with a similar purpose. It consists of a bottle on which is screwed a cap provided with a rod which is fixed a brush which constantly soaks in the product to be applied. This system guarantees the non-drying of the hair bundle, when the applicator is not used, but has three drawbacks: need to constantly re-soak the brush in the bottle for continuous use, risk of capsizing the bottle and thickening of the produced indoors, by evaporation, when using the brush.

Pour remédier à ces inconvénients, certains inventeurs ont imaginé des pinceaux solidaires de réservoirs en forme de stylo et l'un d'entre eux a même été commercialisé, dans le domaine du cosmétique. Toutefois, leur mode de fonctionnement peu pratique et la complexité de leur mécanisme, conférant un prix de revient excessif', n'ont pas contribué à la vulgarisation attendue. To overcome these drawbacks, some inventors have designed brushes solidarity pen-shaped tanks and one of them has even been marketed in the field of cosmetics. However, their impractical mode of operation and the complexity of their mechanism, conferring an excessive cost price, have not contributed to the expected extension.

Le dispositif selon l'invention permet de remédier à tous les inconvénients décrits. The device according to the invention overcomes all the disadvantages described.

Utilisant le principe d'une pompe atmosphérique manuelle, son usage est des plus commodes. Il nécessite de simples pressions de doigts, appliqués sur une partie déterminée de son réservoir tubulaire, pour alimenter en produit le pinceau et l'étendre sur les parties à couvrir, sans changer la position de la main sur l'applicateur. Très peu de pièces sont nécessaires pour sa mise en oeuvre, laissant augurer un prix de revient assez modéré. Il permet de gagner un temps appréciable, en supprimant l'imprégnation répétitive du pinceau dans le récipient contenant le produit à appliquer. L'évaporation de celui-ci n'est plus à craindre, du fait de l'étanchéité parfaite du dispositif. Using the principle of a manual atmospheric pump, its use is most convenient. It requires simple finger pressure, applied to a specific part of its tubular reservoir, to supply the product with the brush and spread on the parts to be covered, without changing the position of the hand on the applicator. Very few parts are necessary for its implementation, suggesting a fairly moderate cost price. It saves valuable time by eliminating the repetitive impregnation of the brush in the container containing the product to be applied. The evaporation of the latter is no longer to be feared, because of the perfect tightness of the device.

Selon le mode de réalisation du dispositif, qui parait le plus opportun, le réservoir distributeur de produit épouse la forme d'un tube de dimension utile, dont une partie est rendue élastique par amincissement de la paroi. Ce réservoir comporte, à l'une de ses extrémités, un embout tronconique, pourvu d'un passage axial longitudinalement rainuré, lequel est équipé d'une tige munie d'un faisceau de poils qui dépasse de l'orifice libre de l'embout. Quand on presse la partie élastique du réservoir remplissant la fonction de pompe atmosphérique, pinceau dirigé vers le bas, le produit qu'il contient est chassé vers l'embout, circule le long des rainures et imbibe le pinceau, sur sa périphérie, aussi fréquemment que l'exige l'objet à recouvrir. Hors utilisation, un double capuchon étanche coiffe le dispositif, afin de garantir le non séchage du faisceau de poils et la protection de la partie amincie et fragilisée du réservoir. According to the embodiment of the device, which seems most appropriate, the product dispenser tank takes the form of a useful size tube, a portion of which is made elastic by thinning of the wall. This tank comprises, at one of its ends, a frustoconical tip, provided with a longitudinally grooved axial passage, which is equipped with a rod provided with a bundle of bristles which protrudes from the free orifice of the nozzle . When pressing the elastic portion of the reservoir performing the function of atmospheric pump, brush directed downwards, the product it contains is driven towards the tip, circulates along the grooves and soaks the brush on its periphery, as frequently as required by the object to be covered. Out of use, a double waterproof cap covers the device, in order to guarantee the non-drying of the pile bundle and the protection of the thinned and weakened part of the tank.

Pour fixer l'objet de l'invention sans cependant le limiter, les deux planches de dessins annexées illustrent, à titre d'exemple, un mode de réalisation du dispositif. To fix the object of the invention without however limiting it, the two plates of attached drawings illustrate, by way of example, an embodiment of the device.

Tel qu'il est représenté aux figures 1 et 2, le dispositif comporte un réservoir tubulaire 1, réalisé en matière rigide ou semi rigide et fermé à l'une de ses extrémités. Ce réservoir 1 comporte, à proximité de son extrémité distale, une portion souple et élastique 2 faisant office de pompe atmosphérique, obtenue, par exemple, en amincissant au moulage la matière dans laquelle est fabriquée ledit réservoir 1. Un embout 19 ferme le réservoir 1 à cette extrémité distale. Il est constitué d'un goulot 3, de forme tronconique, pourvu d'un passage axial 4, muni d'une ou de préférence plusieurs rainures longitudinales 5, à l'intérieur duquel est fixée une tige 6, dont l'extrémité proximale déborde utilement dans le réservoir 1 pour interdire l'obturation des rainures 5 par les billes 7 de malaxage du produit 18, logées dans ledit réservoir 1. L'extrémité distale de la tige 6 est disposée en retrait par rapport à l'orifice de sortie 9 du passage axial 4 et porte un faisceau de poils 8 qui dépasse, d'environ trois fois la valeur de son diamètre, du même orifice de sortie 9, ces mesures favorisant efficacement l'imprégnation du pinceau 8 et l'étalement rapide du produit 18, sur la surface à recouvrir. As shown in Figures 1 and 2, the device comprises a tubular reservoir 1, made of rigid or semi-rigid material and closed at one of its ends. This reservoir 1 comprises, near its distal end, a flexible and resilient portion 2 acting as an atmospheric pump, obtained, for example, by thinning the molding material in which is made said reservoir 1. A nozzle 19 closes the reservoir 1 at this distal end. It consists of a neck 3 of frustoconical shape, provided with an axial passage 4, provided with one or preferably several longitudinal grooves 5, inside which is fixed a rod 6, whose proximal end overflows usefully in the tank 1 to prohibit the closing of the grooves 5 by the balls 7 of mixing of the product 18, housed in said reservoir 1. The distal end of the rod 6 is set back with respect to the outlet orifice 9 the axial passage 4 and carries a bundle of bristles 8 which exceeds, by about three times the value of its diameter, the same outlet orifice 9, these measures effectively promoting the impregnation of the brush 8 and the rapid spreading of the product 18 , on the surface to be covered.

Sur les figures 1 et 3, le goulot 3 de l'embout 19 est muni extérieurement, près du réservoir 1, d'un filetage 10 qui permet, à un capuchon interne 11 (fig.5 et 6), de forme tronconique, de venir se visser sur le dispositif et d'assurer son étanchéité en écrasant un joint souple 12, placé au bout du filetage 10, contre le débordement périphérique 13 du réservoir 1. Coiffant le capuchon interne 11 (fig. 7, 8 et 9), un capuchon externe 14, muni d'au moins une rainure longitudinale interne 15, coulisse sur le dispositif, jusqu'à venir masquer, pour la protéger des heurts, la paroi fragilisée de la pompe atmosphérique 2 du réservoir 1, en alignant sa rainure interne 15 sur l'ergot 16 dont est muni le capuchon 11, ainsi que sur l'ergot 17, situé sur le réservoir 1 (fig.1, 3, 4 et 7). Ce capuchon externe 14 a une double fonction: protéger la pompe 2 mais également assurer la fermeture complète du capuchon interne 11, par l'alignement obligé de l'ergot 16 avec l'ergot 17 (fig.7, 8, et 9). In FIGS. 1 and 3, the neck 3 of the nozzle 19 is provided externally, near the tank 1, with a thread 10 which makes it possible, for an internal cap 11 (FIGS. 5 and 6), of frustoconical shape, to screw on the device and ensure its sealing by crushing a flexible seal 12, placed at the end of the thread 10, against the peripheral overflow 13 of the tank 1. Styling the inner cap 11 (Figures 7, 8 and 9), an outer cap 14, provided with at least one internal longitudinal groove 15, slides on the device, until it comes to mask, to protect it from the clashes, the weakened wall of the atmospheric pump 2 of the tank 1, by aligning its internal groove 15 on the lug 16 which is provided with the cap 11, and on the lug 17, located on the tank 1 (Fig.1, 3, 4 and 7). This external cap 14 has a dual function: protect the pump 2 but also ensure the complete closure of the inner cap 11, by the alignment of the lug 16 with the lug 17 (Fig.7, 8, and 9).

Lorsque les deux capuchons i l et 14 sont retirés et que l'on incline le dispositif (fig. 1 et 2), pinceau 8 dirigé vers le bas, il suffit d'appuyer du bout des doigts sur la portion élastique 2 du réservoir 1 pour augmenter la pression atmosphérique à l'intérieur du dispositif et chasser un peu du produit 18 qu'il contient le long des rainures 5 du goulot 3, jusqu'au faisceau de poils 8. Quand on relâche la pression des doigts sur la pompe 2, sa paroi élastique tend à reprendre sa forme initiale, en aspirant une quantité d'air égale à celle du produit expulsé. When the two caps 11 and 14 are removed and that the device is inclined (FIG 1 and 2), brush 8 directed downwards, simply press with the fingertips on the elastic portion 2 of the tank 1 to increase the atmospheric pressure inside the device and drive some of the product 18 it contains along the grooves 5 of the neck 3, to the bundle of bristles 8. When the pressure of the fingers is released on the pump 2, its elastic wall tends to return to its original shape, sucking a quantity of air equal to that of the expelled product.

L'opération peut être renouvelé autant de fois que le nécessite la reimbibition du pinceau 8. The operation can be renewed as many times as the reimbibition of the brush 8 requires.

Le dispositif, objet de l'invention, peut être utilisé dans tous les cas où l'imprégnation d'un pinceau gagne à être assuré d'une manière continue, pendant l'application d'un produit, sans qu'il soit nécessaire de le nettoyer après usage, par crainte de séchage du faisceau de poils. Ce dispositif peut être utilisé dans le domaine cosmétique, domestique, artistique, médical et industriel, pour l'application des peintures, teintures, colles, certains produits pharmaceutiques et, bien sûr, les vernis à ongles. The device, object of the invention, can be used in all cases where the impregnation of a brush to be assured in a continuous manner, during the application of a product, without it being necessary to clean it after use, for fear of drying the bundle of hair. This device can be used in the cosmetic, domestic, artistic, medical and industrial fields, for the application of paints, dyes, glues, certain pharmaceutical products and, of course, nail polish.
