- the external face 107 of the dispensing dome 104 uniformly delivers product.
- a protective cover 129 is provided to protect the application member 104.
- the user applies the external face 107 of the dome 104 against the surface to be treated, for example the skin to be depilated from one leg. He then moves the applicator laterally. This results in a friction force which results in the deformation of the flexible element 130, and, consequently, a substantially radial displacement of the cup 124, relative to the reservoir 102 and relative to the axis of the valve 120. It a changeover ensues lateral of the rod 122 and therefore an opening of the valve, with simultaneous ejection of the depilation gel conditioned under pressure in the reservoir 102.
- the gel arrives on the internal face 109 of the dispensing dome 104, then it is distributed over this whole face internal and, under the effect of the distribution pressure, it passes through the frit constituting the dome 104 to come flush with the external face 107 of this dome.
- the gel is then distributed by friction on the leg; during an excess of product, the friction force decreases, which causes the valve 120 to close under the effect of the elastic return means, provided inside the valve.
- this applicator is particularly reliable, and there can be no leakage.
- the approval of a topical application by means of this applicator is very satisfactory, because the user feels a soft and non-greasy application with a freshness effect.
- the application can be carried out directly without prior turning over of the applicator.

Description
La présente invention se rapporte à un applicateur de produit crémeux, pâteux ou se présentant sous forme de mousse, ayant un organe d'application poreux rigide, servant d'élément applicateur du produit sur la surface devant recevoir le produit, selon la première partie de la revendication 1 (EP-A-0 155 349).The present invention relates to an applicator for a creamy, pasty product or in the form of a foam, having a rigid porous application member, serving as an applicator element for the product on the surface to receive the product, according to the first part of claim 1 (EP-A-0 155 349).
Plus précisément, la présente invention se rapporte à un applicateur de pâte, crème, de mousse ou gel, notamment un applicateur destiné à l'application, par voie topique, sur la peau d'un utilisateur d'un produit à action cosmétique ou dermopharmaceutique, tel qu'une crème déodorante, parfumante, amincissante ou épilatoire, une crème pour le visage, ou encore un gel pour traiter le cuir chevelu.More specifically, the present invention relates to an applicator for paste, cream, foam or gel, in particular an applicator intended for the application, topically, to the skin of a user of a product with cosmetic or dermopharmaceutical action. , such as a deodorant, perfuming, slimming or depilatory cream, a face cream, or even a gel to treat the scalp.
Dans le cas particulier de produit déodorant ou antitranspirant, on a déjà proposé d'assurer l'application du produit au moyen d'un bâton solide, dit "raisin", contenant l'actif à appliquer sur la peau de l'utilisateur ; ce raisin est conditionné, habituellement, dans un étui permettant son déplacement sur la peau au fur et à mesure de sa consommation.In the particular case of deodorant or antiperspirant product, it has already been proposed to ensure the application of the product by means of a solid stick, called "grape", containing the active ingredient to be applied to the skin of the user; this grape is usually packaged in a case allowing it to be moved over the skin as it is consumed.
Les inconvénients d'une telle présentation sont, d'une part, la nécessité pour le conditionnement du produit d'outillages spéciaux et onéreux et, d'autre part, la conservation du raisin qui n'est généralement pas parfaitement assurée. En effet, la composition solide utilisée contient un important pourcentage d'alcool et le conditionnement n'est généralement pas suffisamment étanche pour empêcher l'évaporation de l'alcool, et donc le dessèchement du produit. Il se produit donc une dégradation du raisin qui rend inutilisable le produit, notamment en fin de consommation. En outre, le confort d'utilisation n'est pas parfaitement satisfaisante par manque de souplesse du raisin. De plus, notamment sur les zones sensibles du corps comme les aisselles, les compositions connues donnent une impression d'application grasse. En résumé, l'utilisateur souhaite une application douce et non grasse du produit déodorant avec un effet rafraîchissant.The disadvantages of such a presentation are, on the one hand, the need for packaging the product of special and expensive tools and, on the other hand, the conservation of the grape which is generally not perfectly ensured. Indeed, the solid composition used contains a large percentage of alcohol and the packaging is generally not sufficiently tight to prevent the evaporation of the alcohol, and therefore the drying of the product. There is therefore a degradation of the grapes which makes the product unusable, especially at the end of consumption. In addition, the comfort of use is not perfectly satisfactory due to the grape's lack of flexibility. In addition, especially on sensitive areas of the body such as the armpits, the known compositions give the impression of oily application. In summary, the user wants a gentle, non-greasy application of the deodorant product with a refreshing effect.
On a déjà proposé de remédier à ces inconvénients en proposant un applicateur du type flacon, qui contient une composition liquide, ce flacon étant surmonté d'une tête de distribution portant un dôme distributeur réalisé en un matériau poreux rigide servant d'élément applicateur. Ce type d'applicateur est décrit, par exemple, dans les documents EP-A-0 167 657 et FR-A-2 647 034.It has already been proposed to remedy these drawbacks by proposing an applicator of the bottle type, which contains a liquid composition, this bottle being surmounted by a dispensing head carrying a dispensing dome made of a rigid porous material serving as an applicator element. This type of applicator is described, for example, in documents EP-A-0 167 657 and FR-A-2 647 034.
Selon le document EP-A-0 155 349 l'applicateur comporte des moyens de compression assistant le passage du produit par capillarité.According to document EP-A-0 155 349 the applicator comprises compression means assisting the passage of the product by capillary action.
L'inconvénient de ce type de conditionnement est double : d'une part, pour assurer la fermeture du flacon lorsque le produit n'est pas utilisé, il est nécessaire de prévoir une tête de distribution relativement compliquée, ce qui augmente de façon importante le coût du conditionnement d'autre part, pour appliquer le produit sur la peau, il est nécessaire, d'effectuer une action préalable amenant le liquide dans le dôme poreux. Dans ces deux documents antérieurs, cette action consiste en un retournement préalable du flacon pour que le produit descende par gravité dans le dôme poreux (tête en bas). En outre, ce type de conditionnement nécessite une composition peu visqueuse, en règle générale à forte teneur en alcool, ce qui limite d'une part l'emploi de nouvelles matières premières pour le formulateur. Par ailleurs, les compositions corporelles alcooliques ne sont pas très «cosmétiques» et risquent d'être mal supportées par le consommateur, notamment à peau sensible. D'autre part, lorsque cet applicateur se trouve couché, par exemple lors d'un voyage de l'utilisateur, il se produit des fuites de produit, notamment lorsque le capot de protection est mal fermé, ce qui est préjudiciable.The disadvantage of this type of packaging is twofold: firstly, to ensure the closure of the bottle when the product is not used, it is necessary to provide a relatively complicated dispensing head, which significantly increases the cost of packaging on the other hand, to apply the product to the skin, it is necessary to perform a prior action bringing the liquid into the porous dome. In these two previous documents, this action consists of a prior inversion of the bottle so that the product descends by gravity into the porous dome (upside down). In addition, this type of packaging requires a low-viscosity composition, as a rule to high alcohol content, which limits on the one hand the use of new raw materials for the formulator. Furthermore, alcoholic body compositions are not very "cosmetic" and risk being poorly supported by the consumer, in particular with sensitive skin. On the other hand, when this applicator is lying down, for example during a travel of the user, product leaks occur, especially when the protective cover is not closed properly, which is detrimental.
La présente invention permet d'éviter les inconvénients mentionnés ci-dessus en proposant le produit industriel nouveau qui consiste en un applicateur contenant un produit visqueux, d'application très douce ; cette application peut être effectuée aisément sur tous les endroits du corps humain, et plus spécialement sur les aisselles et les jambes, avec un étalement régulier et homogène du produit. Cet applicateur peut même être utilisé avec un mouvement de massage en vue de favoriser la pénétration du produit dans la peau.The present invention makes it possible to avoid the drawbacks mentioned above by proposing the new industrial product which consists of an applicator containing a viscous product, of very gentle application; this application can be carried out easily on all the places of the human body, and more especially on the armpits and the legs, with a regular and homogeneous spreading of the product. This applicator can even be used with a massage movement to promote the penetration of the product into the skin.
Ainsi, la présente invention se rapporte selon la revendication 1 à un applicateur d'un produit de consistance visqueuse, comportant un réservoir de de produit et un organe d'application rigide comportant des pores communiquant entre eux dans toutes les directions caractérisé en ce que la porosité est telle que le passage du produit au travers des pores par gravité et/ou par capillarité est empêché pour le produit ayant une viscosité choisie, et en ce qu'il comprend, en outre, des moyens de compression du produit aptes à produire une pression suffisante sur le produit pour le pousser au travers des pores, lors de la distribution d'une dose de produit.Thus, the present invention relates according to
Avantageusement, les moyens de compression sont de nature mécanique et comportent, selon une première variante de réalisation, un piston associé à un moyen de manoeuvre du piston. Ce moyen de manoeuvre peut être constitué par une tige mobile en rotation, munie d'un filetage solidaire d'un élément d'actionnement tel qu'une molette, le filetage de la tige coopérant avec un filetage complémentaire pratiqué dans le piston.Advantageously, the compression means are mechanical in nature and comprise, according to a first alternative embodiment, a piston associated with a means for operating the piston. This operating means can be constituted by a rod movable in rotation, provided with a thread integral with an actuating element such as a knurling wheel, the thread of the rod cooperating with a complementary thread made in the piston.
Dans ce cas, l'élément d'actionnement de l'ensemble applicateur de l'invention a, avantageusement, une forme ovale ou allongée perpendiculairement à l'axe de rotation de la tige, de sorte que cet élément forme un bras de levier facilitant la remontée du piston, lors de l'utilisation.In this case, the actuating element of the applicator assembly of the invention advantageously has an oval or elongated shape perpendicular to the axis of rotation of the rod, so that this element forms a lever arm facilitating raising the piston during use.
L'organe d'application est avantageusement un dôme ayant une surface d'application continue, sensiblement convexe ou plane, pouvant comporter une légère dépression. Ce dôme distributeur peut être constitué d'un matériau fritté rigide, non déformable en céramique ou en plastique, obtenu notamment par compression à chaud de particules de matière plastique ou céramique. Ce fritté comporte des pores communiquant entre eux, de façon omnidirectionnelle, et a une porosité comprise allant de 1 µm à 500 µm, la gamme de porosité préférée s'étendant de 50 µm à 300 µm.The applicator member is advantageously a dome having a continuous application surface, substantially convex or planar, which may include a slight depression. This dispensing dome can be made of a rigid, non-deformable sintered material made of ceramic or plastic, obtained in particular by hot compression of particles of plastic or ceramic material. This frit has pores communicating with each other, in an omnidirectional manner, and has a porosity ranging from 1 μm to 500 μm, the preferred porosity range extending from 50 μm to 300 μm.
Le choix de la porosité est généralement effectué en tenant compte de trois paramètres : d'une part, du débit de passage désiré pour le produit à appliquer, d'autre part, de l'état de surface du dôme poreux, qui doit être compatible avec la surface à traiter, et enfin de la viscosité du produit. Pour définir la porosité, de façon connue, on mesure le débit de passage d'un produit à travers une épaisseur donnée du fritté sous une différence de pression prédéterminée et on en déduit la section équivalente d'une canalisation assurant le même débit dans les mêmes conditions. Cette section équivalente permet ainsi la détermination du diamètre moyen d'un pore quand on connaît statistiquement le nombre de pores par unité de surface du dôme.The choice of porosity is generally made taking into account three parameters: on the one hand, the desired flow rate for the product to be on the other hand, apply the surface condition of the porous dome, which must be compatible with the surface to be treated, and finally the viscosity of the product. To define the porosity, in a known manner, the flow rate of a product is measured through a given thickness of the frit under a predetermined pressure difference and the equivalent section of a pipe is deduced therefrom ensuring the same flow rate in the same conditions. This equivalent section thus allows the determination of the average diameter of a pore when we statistically know the number of pores per unit area of the dome.
Lorsque le dôme distributeur est réalisé en un fritté de matière plastique, il peut être constitué par des résines synthétiques telles que des polyéthylènes de haute ou basse densité, des polypropylènes ou des fluorures de polyvinyle. En variante, le dôme peut être réalisé, également, en une mousse synthétique rigide à cellules ouvertes.When the dispensing dome is made of a plastic frit, it can be made of synthetic resins such as high or low density polyethylenes, polypropylenes or polyvinyl fluorides. Alternatively, the dome can also be made of a rigid synthetic foam with open cells.
Pour pouvoir effectuer une application du produit en toute douceur, le dôme a, avantageusement, une surface d'application dont la rugosité moyenne est choisie dans la gamme allant de 0,5 µm à 100 µm, et de préférence dans la gamme allant de 6 µm à 50 µm.In order to be able to apply the product smoothly, the dome advantageously has an application surface the average roughness of which is chosen from the range from 0.5 μm to 100 μm, and preferably from the range from 6 µm to 50 µm.
Selon une autre variante de réalisation intéressante, les moyens de compression peuvent comporter un gaz propulseur et une valve de distribution coopérant avec la tête de distribution. Cette valve est actionnée par l'utilisateur lors de l'application du produit sur la peau. On peut avantageusement prévoir que cette valve de distribution soit une valve à ouverture par basculement latéral de sa tige émergente. Le produit peut être renfermé dans une poche disposée à l'intérieur du réservoir, séparant le produit et le gaz propulseur. Dans ce cas, si le produit est un produit moussant, la poche contient, en outre un agent d'expansion de mousse tel que l'isobutane, par exemple.According to another interesting alternative embodiment, the compression means may comprise a propellant gas and a distribution valve cooperating with the distribution head. This valve is actuated by the user when the product is applied to the skin. Advantageously, it is possible to provide for this dispensing valve to be an opening valve by lateral tilting of its emerging rod. The product can be enclosed in a pocket disposed inside the tank, separating the product and the propellant. In this case, if the product is a foaming product, the bag also contains a foaming agent such as isobutane, for example.
Selon cette réalisation, le réservoir est un bidon cylindrique, dont le sommet porte une valve de distribution. Un moyen de fixation est prévu sur le bidon pour fixer une frette, cette dernière portant la tête de distribution.According to this embodiment, the reservoir is a cylindrical container, the top of which carries a dispensing valve. A fixing means is provided on the container for fixing a hoop, the latter carrying the dispensing head.
Pour augmenter encore la douceur d'application du produit, des moyens de suspension élastiques peuvent être prévus, disposés, par exemple, entre l'organe d'application et le réservoir de produit, et plus particulièrement, entre l'organe d'application et la frette.To further increase the smoothness of application of the product, elastic suspension means can be provided, arranged, for example, between the application member and the product reservoir, and more particularly, between the application member and the fret.
Dans la variante à gaz propulseur, les moyens de suspension peuvent avantageusement relier l'extrémité de la frette, qui est la plus éloignée de sa zone de fixation sur le bidon, à la périphérie du support du dôme distributeur. Dans ce cas, la frette et les moyens de suspension peuvent être constitués d'une paroi continue entourant la valve de distribution de la tête de distribution fixée sur le réservoir. Bien entendu, ces moyens de suspension pourraient également être réalisés de façon discontinue, par une pluralité de secteurs successifs, par exemple sous forme de languettes.In the propellant variant, the suspension means can advantageously connect the end of the hoop, which is furthest from its zone of attachment to the container, at the periphery of the support of the dispensing dome. In this case, the hoop and the suspension means may consist of a continuous wall surrounding the dispensing valve of the dispensing head fixed on the reservoir. Of course, these suspension means could also be produced discontinuously, by a plurality of successive sectors, for example in the form of tongues.
Selon un mode de réalisation particulièrement économique, la tête de distribution est réalisée d'une seule pièce par moulage de matière plastique. Avantageusement, la tête de distribution est, hormis les moyens de suspension du dôme distributeur, une pièce ayant un axe de révolution, qui est généralement l'axe du bidon.According to a particularly economical embodiment, the dispensing head is made in one piece by molding plastic material. Advantageously, the dispensing head is, apart from the means for suspending the dispensing dome, a part having an axis of revolution, which is generally the axis of the container.
Selon une autre variante encore de réalisation, les moyens de compression peuvent comporter une pompe de distribution coopérant avec un bras de levier articulé avec la tête de distribution. Cette pompe est actionnée par l'utilisateur lors de l'application du produit sur la peau.According to yet another alternative embodiment, the compression means may comprise a dispensing pump cooperating with a lever arm articulated with the dispensing head. This pump is actuated by the user when the product is applied to the skin.
Selon une autre variante, la pompe peut être une pompe à air, créant une surpression dans le réservoir, cette surpression agissant sur le produit pour en provoquer sa distribution.According to another variant, the pump can be an air pump, creating an overpressure in the tank, this overpressure acting on the product to cause its distribution.
La consistance du produit à appliquer est visqueuse ; avantageusement celle-ci est choisie dans la gamme allant de 50 mPa·s à 7 Pa·s, et de préférence dans la gamme allant de 90 mPa·s à 5 Pa·s.The consistency of the product to be applied is viscous; advantageously this is chosen in the range going from 50 mPa · s to 7 Pa · s, and preferably in the range going from 90 mPa · s to 5 Pa · s.
L'invention a encore pour objet un déodorant selon la revendication 12 comportant un réservoir d'un produit déodorant ou antitranspirant, un organe d'application rigide du produit pourvu de pores communiquant entre eux dans toutes les directions la porosité est telle que le passage du produit au travers les pores par gravité et/ou capillarité est empêché pour le produit ayant une viscosité choisie, et des moyens de compression du produit aptes à produire une pression suffisante sur le produit pour assurer son passage à travers les pores, lors de l'application du produit.The invention also relates to a deodorant according to
Avantageusement, l'organe d'application a la forme d'un dôme.Advantageously, the applicator member has the shape of a dome.
Pour mieux faire comprendre la présente invention, on va en décrire maintenant, à titre d'exemples purement illustratifs et nullement limitatifs, deux modes de réalisation d'applicateurs conforme à l'invention, représentés sur les dessins annexés.To better understand the present invention, we will now describe, by way of purely illustrative and in no way limitative, two embodiments of applicators according to the invention, shown in the accompanying drawings.
La figure 1 représente un applicateur, selon l'invention, en coupe axiale, selon un premier mode de réalisation de l'invention, en position de stockage.FIG. 1 represents an applicator, according to the invention, in axial section, according to a first embodiment of the invention, in the storage position.
La figure 1a est une vue selon la direction Ia-Ia de la figure 1.FIG. 1a is a view in the direction Ia-Ia of FIG. 1.
La figure 2 représente, en coupe axiale, un second mode de réalisation d'un applicateur de l'invention.FIG. 2 represents, in axial section, a second embodiment of an applicator of the invention.
Ainsi, l'applicateur 1 montré sur la figure 1, comporte un réservoir 2 renfermant un produit P, par exemple une crème désodorisante et comportant un corps cylindrique 9 ayant un axe longitudinal A. La section du corps perpendiculaire à l'axe peut être circulaire, mais on préfère, suivant la présente réalisation, une section ovale, pour des raisons expliquées plus loin.Thus, the
Sur cette figure, ce corps cylindrique 9 comporte à une de ses extrémités une tête de distribution 3 munie d'un organe d'application 4 poreux, rigide et non déformable, en forme de dôme. Cette tête 3 comporte, en outre, une zone 28 de diamètre réduit qui constitue le siège d'un capot de protection 29, dont la section interne correspond à la section externe de la zone 28. La deuxième extrémité du corps 9, opposée à l'organe 4, comporte un élément d'actionnement 10 en forme de poignée allongée, de même section ovale que le réservoir, cette poignée étant montée pivotante autour de l'axe A de l'ensemble.In this figure, this cylindrical body 9 has at one of its ends a dispensing
La paroi 10a latérale de l'élément d'actionnement 10 constitue une surface de préhension qui est accessible sur toute la périphérie de l'élément 10. Un utilisateur peut ainsi saisir l'élément 10 et le faire pivoter autour de l'axe A, comme symbolisé sur la figure 1 par la flèche F.The side wall 10a of the
En particulier, l'élément 10 offre des zones d'appui préférentielles, repérées sur la figure 1a, sur lesquelles on va appliquer une force symbolisée par deux flèches Fa. On comprend que le couple de forces Fa que l'on exerce, peut être un couple important, du fait de la forme allongée de l'élément 10.In particular, the
Comme représenté sur la figure 1, le corps 9 comporte intérieurement un piston 6 dont la section correspond précisément à la section interne du corps 9. Ce piston 6 comporte en son centre un orifice 20 taraudé 12a, traversé par une tige 8 muni d'un filetage 12. Cette tige 8 s'étend sur presque toute la hauteur du corps 9. La tige 8 est montée librement en rotation autour de l'axe A de l'ensemble, tout en étant immobilisée axialement, grâce à un épaulement 8a tronconique de la paroi de fond 22 du corps 9. Cette paroi 22 présente une forme adaptée pour recevoir la tête tronconique 13 de la tige filetée 8. En effet, la paroi de fond 22 comporte un orifice 14 prolongé vers le bas par un bord tronconique 15, formant un palier pour la partie tronconique de la tête 13 de la tige 8. Le bord tronconique 15 est raccordé à une partie plane 23 de la paroi de fond 22. L'épaulement 8a est entouré d'une manchette élastique 16, pour assurer l'étanchéité de l'intérieur du réservoir 2 vis-à-vis de l'extérieur, empêchant ainsi toute pénétration d'air ambiant qui pourrait entraîner le dessèchement ou la dégradation du produit conditionné.As shown in FIG. 1, the body 9 internally comprises a
La tête 13 de la tige 8 est solidaire de l'élément d'actionnement 10. En effet, cette tête se raccorde à un plateau 24 de forme ovale de même dimension que la section du corps 9. Les bords de ce plateau 24 se raccordent à la paroi 10a latérale de l'élément d'actionnement 10. Le fond de l'élément 10 est fermé par un plateau 10b qui a la même forme et la même dimension que le plateau 24.The
La partie plane 23 du fond 22 et le plateau 24 sont pourvus de systèmes bossage 25/partie en creux 26, disposés l'un en vis-à-vis de l'autre et coopérant l'un avec l'autre, ce système permettant à l'utilisateur de repositionner aisément l'élément d'actionnement 10 dans le prolongement du corps 9.The
En outre, le piston 6 comporte à sa périphérie une lèvre d'étanchéité 6a qui s'appuie fortement contre la paroi latérale du corps 9, et assure une étanchéité parfaite entre le réservoir 2 et le volume 2a défini entre le piston 6 et le fond 22.In addition, the
Conformément à un aspect intéressant de l'invention, le pas de vis de la tige 8 est choisi en fonction de la viscosité du produit et de la taille des pores 5 de l'organe d'application 4 : pour un produit de viscosité élevée et une taille de pores faible, le pas de vis doit être faible, et inversement.In accordance with an interesting aspect of the invention, the thread of the
L'organe d'application peut être constitué d'un matériau fritté céramique ou plastique, notamment d'un matériau obtenu par compression à chaud de particules ; par exemple, on peut utiliser un fritté obtenu par compression de billes calibrées de polyéthylène, ce fritté ayant une porosité comprise entre 1 µm et 200 µm. Pour cette gamme de porosité, le pas de vis doit être faible.The applicator member may consist of a ceramic or plastic sintered material, in particular of a material obtained by hot compression of particles; for example, a frit obtained by compression of calibrated polyethylene beads can be used, this sinter having a porosity of between 1 μm and 200 μm. For this porosity range, the screw pitch must be low.
Dans l'exemple considéré, l'organe d'application 4 a une porosité de 40 µm environ. Sa face externe 7 a une forme bombée dont la convexité est tournée vers l'extérieur. La rugosité de la surface 7 du dôme 4 est telle que la moyenne Ra des écarts de rugosité est de l'ordre de 15 µm ; Ra est la moyenne arithmétique des écarts entre la surface réelle et la surface médiane ; cette moyenne arithmétique est donnée par la formule:
Le produit P contenu dans le réservoir 2 a une viscosité de 120 mPa·s environ.The product P contained in the tank 2 has a viscosity of approximately 120 mPa · s.
Cet applicateur permet une application douce et aisée sur une zone large de la peau, par exemple sur les aisselles.This applicator allows a soft and easy application on a wide area of the skin, for example on the armpits.
Sur la figure 2 on a désigné par la référence 101 l'applicateur de produit de consistance visqueuse selon une autre variante de réalisation de l'invention.In FIG. 2, the product applicator of viscous consistency has been designated by the
En se référant à cette figure, on voit que l'on a désigné par 102 le réservoir pressurisé de l'applicateur. Ce réservoir est un bidon cylindrique de section droite circulaire, dont le sommet est conformé en une ogive 110, qui porte, à sa partie supérieure, une coupelle de valve 112 solidarisée du bidon par un bourrelet de sertissage 114. La coupelle de valve porte, selon son axe A, une valve de distribution 120 comportant une tige émergente 122 ; l'ouverture de la valve 120 s'effectue par basculement latéral de la tige émergente 122.Referring to this figure, it can be seen that the pressurized reservoir of the applicator has been designated by 102. This reservoir is a cylindrical container of circular cross section, the top of which is shaped like a
Dans la zone de jonction de l'ogive 110 avec la paroi cylindrique du réservoir 102, on voit une gorge d'encliquetage périphérique 116.In the junction of the
Dans le réservoir 102, est conditionné sous pression le produit, par exemple un gel d'épilation. Ce gel a une viscosité d'environ 300 mPa·s. La pressurisation du réservoir peut être réalisée, soit en mettant directement le produit en contact avec le gaz propulseur, soit en séparant le produit et le gaz propulseur par un piston mobile ou par une poche souple déformable, ce qui libère, dans ce dernier cas, de l'obligation d'utiliser l'applicateur dans une position déterminée, soit valve en haut, soit valve en bas.In the
Sur le réservoir est fixé une tête de distribution 103, qui comporte, d'une part, une frette cylindrique 118, et d'autre part, une seconde coupelle 124, qui constitue le support de l'organe d'application 104 en forme de dôme, constitué d'un matériau semblable à celui décrit à la figure 1. Cette frette comporte intérieurement, à sa base, un bourrelet d'encliquetage annulaire 117, qui est destiné à coopérer avec la gorge d'encliquetage 116.On the reservoir is fixed a dispensing
La tête de distribution 103 comporte, en outre, un élément souple 130, qui relie la coupelle 124 et la frette 118. L'élément souple 130 est formé par plusieurs languettes régulièrement reparties. La liaison frette - coupelle 124 est effectuée selon une zone arrondie 131, dont la convexité est tournée vers le bourrelet d'encliquetage 117. La frette 118 et l'élément souple 130 ont une forme générale cylindrique et sont disposés coaxialement. La frette est reliée à l'élément souple au niveau de son extrémité libre 119. En outre, l'élément souple 130 se raccorde à la coupelle 124 le long de sa bordure opposée à l'extrémité 119. Dans sa zone centrale, la coupelle 124 est solidaire d'un embout 126 creux de forme cylindrique. Cet embout comporte selon son axe un passage 128, dans lequel est engagée l'extrémité libre de la tige émergente 122 de la valve 120, pour obtenir un raccordement étanche entre cette tige et l'embout 126.The dispensing
Des canaux 125 sensiblement radiaux sont ménagés entre la face interne du support 124 et la face inférieure du dôme distributeur 104, lesdits canaux pouvant être réalisés dans le dôme distributeur lui-même et/ou dans la paroi du support : ces canaux ont l'avantage d'assurer une bonne répartition du produit à distribuer. Ainsi, la face externe 107 du dôme distributeur 104 délivre uniformément du produit.
Un capot de protection 129 est prévu pour protéger l'organe d'application 104.A
Pour mettre en oeuvre l'applicateur ci-dessus, l'utilisateur applique la face externe 107 du dôme 104 contre la surface à traiter, par exemple la peau à épiler d'une jambe. ll déplace alors latéralement l'applicateur. ll en résulte une force de friction qui entraîne la déformation de l'élément souple 130, et, par conséquent, un déplacement sensiblement radial de la coupelle 124, par rapport au réservoir 102 et par rapport à l'axe de la valve 120. Il s'en suit un basculement latéral de la tige 122 et donc une ouverture de la valve, avec éjection simultanée du gel d'épilation conditionné sous pression dans le réservoir 102. Le gel arrive sur la face interne 109 du dôme distributeur 104, puis il se répartit sur toute cette face interne et, sous l'effet de la pression de distribution, il traverse le fritté constitutif du dôme 104 pour venir affleurer sur la face externe 107 de ce dôme.To use the above applicator, the user applies the
Le gel est alors distribué par friction sur la jambe ; lors d'un excès de produit, la force de friction diminue, ce qui entraîne la fermeture de la valve 120 sous l'effet du moyen de rappel élastique, prévu à l'intérieur de la valve.The gel is then distributed by friction on the leg; during an excess of product, the friction force decreases, which causes the
L'utilisation de cet applicateur est particulièrement fiable, et il ne peut y avoir de fuite. En outre, l'agrément d'une application topique au moyen de cet applicateur est très satisfaisante, car l'utilisateur ressent une application douce et non grasse avec un effet de fraîcheur. Par ailleurs, l'application peut être effectuée directement sans retournement préalable de l'applicateur.The use of this applicator is particularly reliable, and there can be no leakage. In addition, the approval of a topical application by means of this applicator is very satisfactory, because the user feels a soft and non-greasy application with a freshness effect. Furthermore, the application can be carried out directly without prior turning over of the applicator.
