Abstract

A dispenser/applicator for a liquid such as a cosmetic or medicinal skin product held under pressure in a container (2), released by lateral movement of a valve stem (5), consists of a cover housing (6) with a support (8, 9) for the applicator (10) connected to the valve stem, and an actuator (16, 20, 22, 30) which controls the opening of the valve and the delivery of the liquid to the applicator. The actuator is made in one piece with the cover housing, and its components pivot about at least two axes (17, 21) lying perpendicular to the axis of the container, so that the valve is opened by a pressure applied on a level with its stem. The applicator support is connected to the valve stem by a flexible coupling which keeps the applicator in one position while the valve stem is being moved. The cover housing is made from a rigid or semi-rigid thermoplastic such as polypropylene, polyethylene or other polyolefin.

Description

La présente invention a trait à un dispositif de distribution et d'application pour liquide, et notamment un dispositif utilisable pour l'application par voie topique, sur la peau d'un produit à action cosmétique ou dermopharmaceutique, tel qu'une mousse, un gel, un déodorant, un produit tenseur de buste, un défatiguant pour jambes lourdes, etc. Des applications dans des domaines autres que la cosmétique peuvent être envisagées, notamment dans le domaine des colles. L'invention concerne également un récipient équipé d'un tel dispositif de distribution et d'application.The present invention relates to a dispensing and application device for liquid, and in particular a device which can be used for topical application, on the skin of a cosmetic or dermopharmaceutical product, such as a foam, gel, deodorant, bust-tensor, anti-fatigue product for heavy legs, etc. Applications in fields other than cosmetics can be envisaged, in particular in the field of adhesives. The invention also relates to a container equipped with such a device for distribution and application.

La demande de brevet FR-A-2 713 060 décrit un dispositif applicateur pour liquide comportant un conteneur du liquide à appliquer sur une surface à traiter et un dôme distributeur relié au conteneur pat une tête de distribution, le dôme distributeur étant réalisé en un matériau poreux adapté à l'application du liquide par simple frottement de la face externe du dôme sur la surface à traiter. Le conteneur est un réservoir pressurisé équipé d'une valve de distribution, le dôme distributeur étant porté par un support qui constitue un élément de la tête de distribution et est mécaniquement lié à un embout apte à coopérer avec la valve pour provoquer son ouverture sous l'action d'une sollicitation mécanique exercée sur le dôme distributeur.Patent application FR-A-2 713 060 describes an applicator device for liquid comprising a container of the liquid to be applied to a surface to be treated and a dispensing dome connected to the container by a dispensing head, the dome dispenser being made of a porous material suitable for applying the liquid by simply rubbing the external face of the dome on the surface to be treated. The container is a pressurized tank equipped with a distribution valve, the dome dispenser being carried by a support which constitutes an element of the head of distribution and is mechanically linked to a nozzle capable of cooperating with the valve to cause it to open under the action of a mechanical stress exerted on the dispensing dome.

Un tel dispositif est utilisé notamment pour des produits à effet froid, effet obtenu par la détente du gaz propulseur en surface du dôme poreux. A titre d'exemple, le produit est un défatiguant pour jambes lourdes, pour lesquelles l'effet froid est très positif par son effet vaso-restricteur des micro-capillaires de surface, ou un tenseur pour le buste, pour lequel, l'effet froid est favorable par l'effet tenseur sur les muscles et la peau soutenant les seins.Such a device is used in particular for products with a cold effect, effect obtained by the expansion of the propellant on the surface of the porous dome. For example, the product is a fatigue reliever for heavy legs, for which the cold effect is very positive by its vaso-restrictive effect of surface micro-capillaries, or a tensor for the bust, for which the cold effect is favorable by the tensor effect on the muscles and skin supporting the breasts.

Si un tel dispositif est tout à fait satisfaisant pour une application sur les jambes, il n'en est pas de même pour les produits destinés à être appliqués sur les seins. En réalité, malgré l'effet froid intense et efficace que l'on obtient avec l'application d'une formule adaptée, il se pose néanmoins un problème lié au confort d'usage. En effet, avec le bouton poussoir à dôme poreux, il est nécessaire d'appliquer sur le dôme une force latérale, et dirigée selon l'axe du bidon pour ouvrir la valve à déformation et faire sortir le produit. Or si ce mouvement se fait naturellement sous les aisselles, avec un bon niveau de confort, il n'en est pas de même pour les seins, dans la mesure ou ceux-ci, plus sensibles, ne supportent pas sans douleur, l'effet réactif de la force d'ouverture de la valve.If such a device is entirely satisfactory for application on the legs, it the same is not true for products intended to be applied to the breasts. In reality, despite the intense and effective cold effect obtained with the application of an adapted formula, there is nevertheless a problem linked to the comfort of use. Indeed, with the porous dome push button, it is necessary to apply on the dome a lateral force, and directed along the axis of the container to open the valve to deformation and release the product. Now if this movement occurs naturally under the armpits, with a good level of comfort, it is not the same for the breasts, insofar as these, more sensitive, cannot bear without pain, the reactive effect of the opening force of the valve.

La demande de brevet EP-A- 0 133 369 décrit une tête de distribution sur laquelle est montée une brosse à dents. La valve est une valve à basculement latéral actionnée au moyen d'un bouton poussoir rapporté, disposé sur le côté du support de la brosse à dents. Un tel dispositif est particulièrement coûteux, en raison du nombre de pièces qu'il met en oeuvre. Par ailleurs, ce nombre de pièces important qui le constituent, augmente d'autant sa fragilité.Patent application EP-A- 0 133 369 describes a dispensing head on which mounted a toothbrush. The valve is a side tilt valve operated by means of an attached push button, located on the side of the support toothbrush. Such a device is particularly expensive, because of the number of pieces it implements. Furthermore, this large number of pieces which constitute it, all the more increases its fragility.

La demande PCT WO 95/03234 décrit un dispositif de distribution offrant plusieurs endroits pour actionner la valve de distribution. L'actionnement de la valve est réalisé par basculement autour d'un axe, d'organes répartis en plusieurs endroits sur la périphérie du dispositif de distribution, ce qui pose principalement deux problèmes. Tout d'abord, une telle conception implique une hauteur importante du bouton poussoir, pour le montage de celui-ci, afin que les pièces d'actionnement puissent venir en appui sur un manchon rigide emmanché sur la tige de valve. Par ailleurs, l'actionnement de la valve entraíne un basculement du manchon de sortie du produit, ce qui provoque une position variable de la sortie de produit.PCT application WO 95/03234 describes a distribution device offering several places to operate the dispensing valve. The valve actuation is produced by tilting around an axis, organs distributed in several places on the periphery of the dispensing device, which mainly poses two problems. First of all, such a design implies a significant height of the push button, for mounting it, so that the actuating parts can come to bear on a rigid sleeve fitted on the valve stem. By elsewhere, the actuation of the valve causes a tilting of the outlet sleeve of the product, which causes a variable position of the product outlet.

La demande de brevet DE 3 023 596 décrit un dispositif d'application d'un produit crémeux sur une surface au moyen d'un dispositif équipé d'une valve à basculement latéral commandée par un organe d'actionnement qui agit sur une portion proche de l'applicateur. Un tel dispositif pose sensiblement les mêmes problèmes que ceux décrits en référence au dispositif de la demande PCT WO 95/03234, à savoir la nécessité d'avoir une tête de distribution de hauteur importante, et le basculement de l'applicateur en réponse à l'actionnement de la valve. De tels problèmes peuvent être rédhibitoires pour certaines applications, notamment pour des produits dont l'application sur des surfaces sensibles notamment, doit être localisée de façon très précise.Patent application DE 3 023 596 describes a device for applying a product creamy on a surface by means of a device fitted with a lateral tilting controlled by an actuating member which acts on a portion close to the applicator. Such a device poses substantially the same problems than those described with reference to the PCT WO application device 95/03234, namely the need for a height distribution head important, and the tilting of the applicator in response to the actuation of the valve. Such problems can be prohibitive for certain applications, especially for products whose application on sensitive surfaces in particular, must be located very precisely.

Aussi, est-ce un des objets de la présente invention que de fournir un dispositif de distribution et d'application d'un produit liquide ne présentant pas les inconvénients mentionnés ci-avant, en référence aux dispositifs de la technique antérieure.It is therefore an object of the present invention to provide a device for distribution and application of a liquid product not having the disadvantages mentioned above, with reference to the devices of the technique anterior.

C'est en particulier un objet de l'invention que de fournir un dispositif pour lequel la fonction d'application du produit est indépendante de la fonction d'actionnement de la valve.It is in particular an object of the invention to provide a device for which the product application function is independent of the actuation function valve.

C'est un autre objet de l'invention que de fournir un dispositif de distribution et d'application d'un liquide, à faibles encombrement et prix de revient, et offrant la possibilité d'un montage simple, avec un nombre de pièces limité. Un tel dispositif permet avantageusement, l'utilisation de techniques industrielles modernes pour sa réalisation, telles que l'injection multimatières.It is another object of the invention to provide a distribution device and application of a liquid, with a small footprint and cost price, and offering the possibility of simple assembly, with a limited number of parts. Such a device advantageously allows the use of modern industrial techniques for its realization, such as multi-material injection.

Selon l'invention, ces objets sont atteints en réalisant un dispositif de distribution et d'application d'un produit liquide maintenu sous pression dans un récipient équipé d'une valve dont l'ouverture est commandée par basculement latéral d'une tige de valve, ledit dispositif comportant : un corps, destiné à être monté sur le récipient, ledit corps définissant un support pour un organe d'application du produit sur une surface à traiter, ledit organe d'application étant en communication avec la tige de valve et ; des moyens d'actionnement pour commander l'ouverture de la valve et l'alimentation en liquide de l'organe d'application, caractérisé en ce que les moyens d'actionnement forment une seule pièce avec le corps, et en ce que les moyens d'actionnement sont articulés autour d'au moins deux axes perpendiculaires à l'axe du récipient, de manière à provoquer l'ouverture de la valve par action sensiblement au niveau de la tige de valve. L'action d'ouverture, directement au niveau de la tige de valve permet, outre le fait de réduire la hauteur du dispositif, d'améliorer le temps de réponse à l'ouverture.According to the invention, these objects are achieved by producing a distribution device and applying a liquid product kept under pressure in a container equipped with a valve whose opening is controlled by lateral tilting of a valve stem, said device comprising: a body, intended to be mounted on the container, said body defining a support for a member for applying the product on a surface to be treated, said application member being in communication with the valve stem and; actuation means for controlling the opening of the valve and the supply of liquid to the application member, characterized in that the actuating means form a single piece with the body, and in this that the actuating means are articulated around at least two axes perpendicular to the axis of the container, so as to cause the opening of the valve by action substantially at the level of the valve stem. The opening action, directly at the valve stem, in addition to reducing the height of the device, improve response time to opening.

Selon un mode de réalisation préféré, ledit organe d'application est en communication avec la tige de valve via des moyens de couplage flexibles de manière à maintenir l'organe d'application sensiblement immobile lors du basculement latéral de la tige de valve.According to a preferred embodiment, said applicator member is in communication with the valve stem via flexible coupling means of so as to keep the applicator member substantially immobile during the lateral tilting of the valve stem.

Avantageusement, les moyens d'actionnement comportent un organe de basculement de la tige de valve, ledit organe de basculement de la tige de valve étant solidaire du corps va une première zone d'articulation autour d'un premier axe, et une seconde zone d'articulation autour d'un second axe.Advantageously, the actuation means comprise a member for valve stem tilting, said valve stem tilting member being integral with the body goes a first area of articulation around a first axis, and a second articulation zone around a second axis.

La seconde zone d'articulation peut relier une surface d'appui pour l'actionnement de la valve, à une surface intermédiaire dont une extrémité est solidaire de l'organe de basculement de la tige de valve, ladite zone d'articulation permettant le pliage de la surface d'appui par rapport à la surface intermédiaire selon un angle inférieur ou égal à 90°. Cette caractéristique avantageuse contribue à réduire encore de manière substantielle la hauteur de la tête de distribution, en réduisant la hauteur nécessaire au passage de l'organe de basculement sous le support de l'organe d'application, lors du montage de la tête de distribution.The second articulation zone can connect a bearing surface for actuation of the valve, to an intermediate surface, one end of which is integral with the valve stem tilting member, said articulation zone allowing folding the bearing surface with respect to the intermediate surface according to a angle less than or equal to 90 °. This advantageous characteristic contributes to further reduce the height of the dispensing head substantially, reducing the height necessary for the passage of the tilting member under the support of the applicator member, during mounting of the dispensing head.

Lesdites première et seconde zones d'articulation peuvent être constituées de charnières films. Ceci rend le dispositif adapté aux techniques de fabrication par moulage, de type injection/moulage.Said first and second articulation zones can consist of hinges films. This makes the device suitable for manufacturing techniques by molding, injection / molding type.

Selon un premier mode de réalisation, les moyens de couplage flexibles comportent un manchon dont une extrémité est montée de manière étanche sur la tige de valve, ledit manchon comportant une surface annulaire extérieure, l'organe de basculement de la tige étant formé d'un élément en appui sur une partie de ladite surface annulaire extérieure. Cette caractéristique contribue à simplifier les problèmes d'étanchéité en réduisant le nombre d'interfaces au niveau desquelles l'étanchéité doit être assurée.According to a first embodiment, the flexible coupling means have a sleeve, one end of which is tightly mounted on the valve stem, said sleeve having an outer annular surface, the member of tilting of the rod being formed of an element bearing on a part of said outer annular surface. This feature helps to simplify sealing problems by reducing the number of interfaces at which sealing must be ensured.

Selon un second mode de réalisation, l'organe de basculement de la tige de valve est constitué d'un élément annulaire emmanché sur la tige de valve, les moyens de couplage flexibles comportant un manchon dont une extrémité est montée de manière étanche sur ledit élément annulaire. Ceci permet de simplifier le montage du dispositif de distribution et d'application sur le récipient.According to a second embodiment, the tilting member of the valve stem consists of an annular element fitted on the valve stem, the means flexible coupling comprising a sleeve, one end of which is mounted sealingly on said annular element. This simplifies assembly of the dispensing and application device on the container.

Les moyens de couplage flexibles peuvent être réalisés en un élastomère thermoplastique. Le corps peut être réalisé en un matériau thermoplastique rigide ou semi rigide, tels que les polypropylènes, les polyéthylènes, ou autres polyoléfines. D'autres matériaux encore peuvent être utilisés selon l'invention.The flexible coupling means can be made of an elastomer thermoplastic. The body can be made of a rigid thermoplastic material or semi rigid, such as polypropylenes, polyethylenes, or others polyolefins. Still other materials can be used according to the invention.

Avantageusement, des moyens permettent de verrouiller sélectivement lesdits moyens d'actionnement. Ainsi, on évite tout actionnement intempestif du dispositif, notamment lors de son transport. De tels moyens de verrouillage peuvent comporter au moins une butée, apte à coopérer avec une portion de bord d'un couvercle, destiné à recouvrir de manière amovible ledit organe d'application.Advantageously, means make it possible to selectively lock the said actuation means. This avoids any untimely actuation of the device, especially during transport. Such locking means may include at least one stop, capable of cooperating with an edge portion a cover, intended to removably cover said applicator member.

Le support comporte au moins un orifice pour la mise en communication de l'organe d'application et des moyens de couplage, ledit orifice pouvant être en partie, obturé par des moyens aptes à casser le jet de produit liquide délivré par la valve. Ceci permet une application plus confortable et plus homogène du produit sur toute la surface de l'organe d'application.The support comprises at least one orifice for the communication of the applicator member and coupling means, said orifice being able to be in part, closed by means capable of breaking the jet of liquid product delivered by the valve. This allows a more comfortable and homogeneous application of the product over the entire surface of the applicator member.

Avantageusement encore, le corps avec les moyens d'actionnement, les moyens de couplage flexibles, et éventuellement l'organe d'application, sont réalisés par moulage dans un dispositif à injection multimatières. Advantageously also, the body with the actuation means, the means flexible coupling, and possibly the applicator member, are produced by molding in a multi-material injection device.

L'organe d'application peut être applicateur à cellules ouvertes ou semi ouvertes, tel que, par exemple, un fritté, une mousse alvéolaire, un élastomère à cellules ouvertes ou semi ouvertes.The applicator member can be an open or semi-open cell applicator, such as, for example, a frit, a cellular foam, a cell elastomer open or semi open.

Le liquide peut être un déodorant corporel, un tenseur de buste, un défatiguant pour jambes lourdes, etc..The liquid can be a body deodorant, a bust tensor, a fatigue-relieving agent for heavy legs, etc.

Selon un autre aspect de l'invention, on réalise également un récipient pressurisé, surmonté d'une valve dont l'ouverture est commandée par basculement latéral d'une tige de valve, caractérisé en ce qu'il comprend un dispositif de distribution et d'application selon l'invention.According to another aspect of the invention, a pressurized container is also produced, surmounted by a valve whose opening is controlled by lateral tilting a valve stem, characterized in that it comprises a dispensing device and of application according to the invention.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • Les figures 1A-1B illustrent un premier mode de réalisation du dispositif de distribution et d'application selon l'invention;
  • la figure 2 illustre un second mode de réalisation du dispositif selon l'invention; et
  • les figures 3A-3D illustrent les étapes du montage du dispositif représenté aux figures 1A-1B.
The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • FIGS. 1A-1B illustrate a first embodiment of the dispensing and application device according to the invention;
  • FIG. 2 illustrates a second embodiment of the device according to the invention; and
  • Figures 3A-3D illustrate the steps of mounting the device shown in Figures 1A-1B.

Ainsi que représenté en coupe à la figure 1A, l'ensemble de distribution comprend un récipient pressurisé 2 à l'aide d'un gaz propulseur, sur lequel est monté un dispositif de distribution et d'application 1 selon l'invention. Le dispositif 1 est monté sur le réservoir 2 par claquage au moyen d'un arrangement bourrelet 3/gorge 4. Sur le col du récipient, est montée par sertissage, une valve, comportant une tige de valve émergente 5. La valve est de préférence à basculement latéral, c'est à dire que son ouverture est actionnée en provoquant un basculement de la tige de valve en dehors de l'axe A du bidon 2. La tête de distribution 1 est constituée principalement d'un corps 6 (ou frette) rigide ou semi rigide, de section transversale correspondante à la section du bidon. Cette section transversale peut être circulaire, ou de forme allongée (rectangulaire, elliptique, ovale, etc.). La surface intérieure de la frette comporte au voisinage de son bord inférieur, un bourrelet 3 apte à coopérer par claquage avec une gorge 4 prévue sur la périphérie du bidon de manière à maintenir la tête de distribution sur le bidon. Le corps 6 est de préférence légèrement conique de manière à faciliter son démoulage.As shown in section in FIG. 1A, the distribution assembly includes a pressurized container 2 using a propellant gas, on which is mounted a dispensing and application device 1 according to the invention. Device 1 is mounted on the tank 2 by snapping by means of a bead arrangement 3 / groove 4. A valve is mounted on the neck of the container, comprising an emerging valve stem 5. The valve is preferably at lateral tilting, i.e. its opening is actuated by causing tilting of the valve stem outside the axis A of the container 2. The head of distribution 1 mainly consists of a rigid or semi-rigid body 6 (or hoop) rigid, of cross section corresponding to the section of the container. This section transverse can be circular, or elongated (rectangular, elliptical, oval, etc.). The inner surface of the hoop has in the vicinity of its edge lower, a bead 3 adapted to cooperate by breakdown with a groove 4 provided on the periphery of the container so as to maintain the dispensing head on the can. The body 6 is preferably slightly conical so as to facilitate its demoulding.

Le corps 6 se présente sous forme d'une jupe 7, dont la hauteur est telle que, en position montée de la tête sur le bidon, la partie supérieure de la jupe soit sensiblement à la hauteur de l'extrémité libre de la tige de valve. La jupe 7 est surmontée d'un plateau 8 de diamètre inférieur au diamètre de la jupe, et relié à la jupe 7 par un épaulement 9. Le plateau 8 définit avec l'épaulement 9, un support pour un organe d'application 10, lequel est monté à force sur son support. Alternativement, on prévoit des moyens de type à déformation élastique, pour l'accrochage de l'applicateur sur son support. De même, bien que dans le mode de réalisation illustré, le couplage entre le support de l'organe d'application et la jupe 7 soit rigide, on pourrait selon une alternative, prévoir un couplage plus souple, voire élastique, au moyen de ponts de matière répartis de manière appropriée sur la périphérie du support, de manière à conférer encore plus de douceur à l'application.The body 6 is in the form of a skirt 7, the height of which is such that, in mounted position of the head on the container, the upper part of the skirt is substantially at the height of the free end of the valve stem. Skirt 7 is surmounted by a plate 8 of diameter less than the diameter of the skirt, and connected to the skirt 7 by a shoulder 9. The plate 8 defines with the shoulder 9, a support for an applicator member 10, which is forcibly mounted on its support. Alternatively, means of the elastic deformation type are provided, for the attachment of the applicator to its support. Likewise, although in the mode illustrated, the coupling between the support of the applicator member and the skirt 7 is rigid, we could alternatively provide more coupling flexible, even elastic, by means of material bridges so distributed appropriate on the periphery of the support, so as to give even more smoothness on application.

Des canaux 32, orientés radialement, sont prévus sur la surface du plateau 8, en regard de l'organe d'application, de manière à permettre une bonne répartition du produit sur toute la surface de l'organe d'application. De tels canaux peuvent être également prévus sur la partie verticale de l'épaulement 9. Un rebord annulaire 11 délimite la zone recevant l'organe d'application 10. Le rebord annulaire 11 forme un décrochement par rapport au bord externe de la jupe 7, de manière à recevoir, sensiblement en alignement avec la jupe 7, un couvercle 12 apte à recouvrir de manière amovible l'organe d'application. Un arrangement gorge/nervure (non représenté) permet de maintenir en place le couvercle sur l'applicateur. Channels 32, oriented radially, are provided on the surface of the plate 8, in look of the applicator body, so as to allow a good distribution of the product over the entire surface of the applicator member. Such channels can be also provided on the vertical part of the shoulder 9. An annular rim 11 delimits the area receiving the applicator member 10. The annular rim 11 forms a recess relative to the outer edge of the skirt 7, so as to receive, substantially in alignment with the skirt 7, a cover 12 capable of covering with removably the applicator member. A throat / rib arrangement (not shown) keeps the cover in place on the applicator.

Alternativement, l'organe d'application est réalisé par injection moulage, en même temps que le reste du dispositif 1, avec lequel il forme une seule et même pièce.Alternatively, the applicator member is produced by injection molding, at the same time time than the rest of the device 1, with which it forms a single piece.

L'applicateur peut être constitué d'un matériau fritté céramique ou plastique, notamment d'un matériau obtenu par compression de particules de matière plastique. Par exemple, on peut utiliser un fritté obtenu par compression de billes calibrées de polyéthylène, ledit fritté ayant une porosité comprise entre 10 µm et 500 µm. Le choix de la porosité est généralement effectué en tenant compte de deux paramètres, d'une part, le débit de passage et, d'autre part l'état de surface du dôme poreux, qui doit être compatible avec la surface à traiter. Lorsque le dôme distributeur est réalisé en un fritté de matière plastique, il peut être constitué par des résines synthétiques telles que des polyéthylènes à haute ou basse densité, des polypropylènes ou des fluorures de polyvinyle. Alternativement, l'organe d'application est constitué d'une mousse alvéolaire, à cellules ouvertes ou semi ouvertes. Alternativement encore, on utilise un matériau à cellules fermées, la remontée du produit sur la surface d'application s'effectuant par des micro canaux réalisés dans l'organe d'application, parallèlement à l'axe du bidon. Avantageusement, l'organe d'application est réalisé en un matériau thermoplastique, par un procédé de bi-injection, en utilisant le même matériau que le matériau constitutif du tube flexible 13, qui fera l'objet d'une description plus détaillée ci-après. On peut toutefois utiliser un matériau différent.The applicator can be made of a ceramic or plastic sintered material, in particular of a material obtained by compression of particles of matter plastic. For example, one can use a sinter obtained by compression of balls calibrated of polyethylene, said sintered material having a porosity of between 10 μm and 500 µm. The choice of porosity is generally made taking into account two parameters, on the one hand, the flow rate and, on the other hand, the surface condition porous dome, which must be compatible with the surface to be treated. When the dispenser dome is made of a plastic frit, it can be made by synthetic resins such as high or low polyethylenes density, polypropylenes or polyvinyl fluorides. Alternately, the applicator member consists of a cellular foam, with open cells or semi open. Alternatively again, cell material is used closed, the ascent of the product on the application surface is effected by micro channels produced in the applicator member, parallel to the axis of the container. Advantageously, the applicator member is made of a material thermoplastic, by a bi-injection process, using the same material as the material of the flexible tube 13, which will be described more detailed below. However, a different material can be used.

Le plateau 8 présente sensiblement en son centre, un orifice 14, qui avantageusement, est obturé en partie par un organe faisant saillie 15, disposé de manière à casser le jet de produit liquide délivré par la valve. Ainsi que mentionné précédemment; l'orifice débouche, sur sa face opposée à l'organe d'application 10, sur un manchon souple 13, constitué par exemple d'un élastomère thermoplastique (de type SEBS®, SANTOPRENE® ou KRATON® par exemple). Avantageusement, le corps 6 avec ses moyens d'actionnement, le manchon souple 13, et éventuellement l'applicateur, sont réalisés par bi-injection, de manière à former une seule et même pièce constituée de deux ou plusieurs matériaux différents. The plate 8 has substantially at its center, an orifice 14, which advantageously, is partially closed by a protruding member 15, arranged so as to break the jet of liquid product delivered by the valve. As mentioned previously; the orifice opens out, on its face opposite to the applicator member 10, on a flexible sleeve 13, consisting for example of an elastomer thermoplastic (such as SEBS®, SANTOPRENE® or KRATON® for example). Advantageously, the body 6 with its actuating means, the sleeve flexible 13, and possibly the applicator, are produced by bi-injection, so as to form a single piece made up of two or more different materials.

Le dispositif de distribution et d'application selon l'invention comprend également des moyens permettant d'actionner la valve. Ces moyens d'actionnement forment selon l'invention, une seule pièce avec le corps de la tête de distribution. Ils sont constitués de préférence, d'un matériau rigide ou semi rigide, et comprennent une première portion 16 articulée au voisinage de la zone d'accrochage du corps 6 sur le bidon 2, autour d'un premier axe 17, perpendiculaire à l'axe A du bidon 2. Dans cette configuration, l'axe 17 est situé à une hauteur selon l'axe A, en dessous de la partie émergente de la tige de valve. La portion 16, délimitée par deux découpes latérales 18, 19 (figure 1B) est, en position de repos, sensiblement en alignement avec le corps 6. L'action d'ouverture de la valve est commandée en appuyant sur cette portion 16, le corps de la tête de distribution étant sensiblement immobile. La portion d'appui 16 est reliée à une portion intermédiaire 20, par une articulation autour d'un second axe 21. L'axe 21 est de préférence, paralléle à l'axe 17, et est situé à une hauteur selon l'axe A, sensiblement au voisinage de l'extrémité supérieure de la tige de valve. Avantageusement, les articulations autour des axes 17 et 21 sont réalisées par des charnières films. En position montée illustrée à la figure 1, la portion intermédiaire 20 est repliée sensiblement à l'équerre par rapport à la zone d'appui 16, de manière à ce que, en position montée de la tête de distribution sur le récipient, l'organe de basculement 22 soit en engagement avec la tige de valve. Le zone d'appui 16 est en alignement avec le corps du dispositif.The dispensing and application device according to the invention also comprises means for actuating the valve. These actuation means form according to the invention, a single piece with the body of the dispensing head. They are preferably made of a rigid or semi-rigid material, and include a first portion 16 articulated in the vicinity of the attachment zone of the body 6 on the can 2, around a first axis 17, perpendicular to the axis A of the can 2. In this configuration, axis 17 is located at a height along axis A, below the emerging part of the valve stem. The portion 16, delimited by two lateral cutouts 18, 19 (FIG. 1B) is, in the rest position, substantially in alignment with the body 6. The opening action of the valve is controlled by pressing on this portion 16, the body of the dispensing head being noticeably immobile. The support portion 16 is connected to a portion intermediate 20, by an articulation around a second axis 21. The axis 21 is of preferably parallel to axis 17, and is located at a height along axis A, substantially in the vicinity of the upper end of the valve stem. Advantageously, the articulations around axes 17 and 21 are produced by film hinges. In the mounted position illustrated in FIG. 1, the portion intermediate 20 is folded substantially at right angles to the support zone 16, so that, in the mounted position of the dispensing head on the container, the tilting member 22 is in engagement with the valve stem. The support zone 16 is in alignment with the body of the device.

L'extrémité de la partie intermédiaire 20, opposée à l'axe 21, se termine par un organe annulaire 22, destiné à être emmanché à force sur la tige de valve 5. Le bord supérieur de l'organe annulaire est connecté de manière étanche à l'extrémité inférieure du manchon 13, l'extrémité supérieure du manchon étant en communication avec l'orifice 14. La connexion peut se faire par tout moyen connu (collage, claquage, ou montage en légère compression, etc.). Ainsi, le tube 13 réalise avantageusement une liaison souple entre la tige de valve et le support de l'organe d'application. Cette liaison souple autorise le basculement de la tige de valve 5, sans induire de mouvement sensible de l'organe d'application 10, en réponse au mouvement de la tige de valve 5. Par ailleurs, lorsque le manchon 13 est en légère compression, l'étanchéité est conservée pendant l'actionnement de la valve et la sortie du produit. Contrairement aux dispositifs monopièces de la technique antérieure discutée dans le préambule de la présente description, et selon lesquels, la force visant à actionner la tige de valve était appliquée nettement au dessus de la tige de valve, selon l'invention, la valve est actionnée en appliquant une force sensiblement au niveau de la tige de valve. Ceci permet de limiter de manière substantielle la hauteur du dispositif de distribution.The end of the intermediate part 20, opposite the axis 21, ends in a annular member 22, intended to be force fitted on the valve stem 5. The upper edge of the annular member is tightly connected to the lower end of the sleeve 13, the upper end of the sleeve being in communication with port 14. Connection can be made by any known means (bonding, breakdown, or mounting in slight compression, etc.). So the tube 13 advantageously makes a flexible connection between the valve stem and the support the application body. This flexible connection allows the tilting of the rod of valve 5, without inducing significant movement of the applicator member 10, in response to the movement of the valve stem 5. Furthermore, when the sleeve 13 is in slight compression, the seal is retained during actuation of the valve and the product outlet. Unlike the one-piece devices of the prior art discussed in the preamble to this description, and that the force to actuate the valve stem was applied clearly above the valve stem, according to the invention, the valve is actuated by applying a force substantially at the valve stem. this allows to limit the height of the dispensing device substantially.

En vue de son utilisation, l'utilisatrice applique l'organe d'application 10 sur la surface à traiter. En appuyant sur la zone 16, elle provoque un déplacement radial de la partie intermédiaire 20, qui provoque le basculement par rapport à l'axe A de la tige de valve 5. Le produit sort par l'intermédiaire de la tige de valve, du manchon 13, de l'orifice 14, des canaux 32, et s'infiltre dans les pores constituant l'organe d'application 10, pour remonter jusqu'à sa surface d'application. L'utilisatrice déplace alors l'applicateur latèralement pour étaler le produit sur toute la surface à traiter. Le produit peut ainsi être appliqué sur n'importe quelle surface, sans avoir à exercer de pression de l'organe d'application sur la surface à traiter, pour provoquer l'ouverture de la valve.In view of its use, the user applies the applicator member 10 to the surface to be treated. By pressing on zone 16, it causes a radial displacement of the intermediate part 20, which causes the tilting with respect to the axis A of the valve stem 5. The product leaves via the valve stem, the sleeve 13, orifice 14, channels 32, and infiltrates into the pores constituting the application member 10, to go up to its application surface. The user then moves the applicator sideways to spread the product over all the surface to be treated. The product can thus be applied to any surface, without having to exert pressure from the application member on the surface to be treated, to cause the valve to open.

Lorsque le couvercle 12 est monté sur l'ensemble, l'extrémité inférieure du couvercle est positionnée entre une butée 23 formée sur la portion intermédiaire 20 des moyens d'actionnement, et le rebord annulaire immobile 11 du support de l'organe d'application. Dans cette position, le couvercle 12, empêche tout mouvement d'ouverture de la valve. Avantageusement, une seconde butée 24 intérieure est prévue sur la portion intermédiaire 20.When the cover 12 is mounted on the assembly, the lower end of the cover is positioned between a stop 23 formed on the intermediate portion 20 actuating means, and the stationary annular rim 11 of the support the application body. In this position, the cover 12 prevents any valve opening movement. Advantageously, a second stop 24 interior is provided on the intermediate portion 20.

Les figures 3A-3D auxquelles il est maintenant fait référence, illustrent les principales étapes du montage de la tête de distribution telle que décrite en référence aux figures 1A-1B. Figures 3A-3D to which reference is now made illustrate the main stages of mounting the distribution head as described in reference to Figures 1A-1B.

Selon un mode de réalisation préférentiel, l'ensemble constituant la tête, est obtenu par moulage en une seule fois, en utilisant des presses à injection multimatières. La figure 3A illustre la tête de distribution telle qu'elle ressort du moulage. Les parties 16 et 20 sont à plat, et les canaux constitutifs de l'organe annulaire 22 se démoulent aisément. La légère conicité de la jupe 7 facilite encore le démoulage par le haut de la zone destinée à recevoir les moyens d'actionnement de la valve. Le tube souple est centré sur l'axe de la tête.According to a preferred embodiment, the assembly constituting the head is obtained by molding in one go, using injection presses multimaterials. FIG. 3A illustrates the dispensing head as it emerges from the molding. Parts 16 and 20 are flat, and the constituent channels of the organ ring 22 can easily be removed from the mold. The slight taper of the skirt 7 further facilitates demoulding from the top of the area intended to receive the means valve actuation. The flexible tube is centered on the axis of the head.

A la figure 3B, on réalise un double pliage des moyens d'actionnement, d'une part autour de l'axe 17, et d'autre part autour de l'axe 21. Avantageusement, l'articulation 21 permet un plage tel que l'angle α entre la portion intermédiaire 20 et la zone d'appui 16 soit inférieur à 90°, de manière à faire passer l'organe annulaire 22 sous le support de l'organe d'application 10, et à pouvoir le mettre en engagement avec la tige de valve, sans nécessiter une hauteur trop importante entre l'axe 17 et le support. Cette caractéristique permet de limiter de manière substantielle la hauteur de l'ensemble 1.In FIG. 3B, a double folding of the actuation means is carried out, on the one hand around axis 17, and on the other hand around axis 21. Advantageously, the articulation 21 allows a range such that the angle α between the intermediate portion 20 and the support zone 16 is less than 90 °, so as to pass the member ring 22 under the support of the applicator member 10, and to be able to put it in engagement with the valve stem, without requiring too great a height between axis 17 and the support. This characteristic makes it possible to limit in a way substantial the height of the whole 1.

A la figure 3C, le mouvement de montage se poursuit jusqu'à ce que la zone d'appui 16 soit sensiblement en alignement avec le reste de la jupe 7.In FIG. 3C, the mounting movement continues until the zone support 16 is substantially in alignment with the rest of the skirt 7.

Dans la position illustrée à la figure 3D, l'organe annulaire 22 a été remonté de manière à être en contact avec l'extrémité inférieure du manchon souple 13. La tête de distribution est ainsi prête pour être montée par claquage sur un récipient 2, l'organe annulaire s'emmanchant sur la tige de valve 5. Les différentes cotes sont calculées de manière appropriée pour que le manchon souple 13 soit en légère compression de sorte que l'étanchéité soit réalisée à l'interface entre le manchon 13 et l'organe annulaire 22. Ainsi, la réalisation des moyens d'actionnement avec deux axes d'articulations perpendiculaires à l'axe du bidon permet, par pliage, successif ou simultané, autour des deux axes, de positionner l'organe annulaire 22 sensiblement au niveau de la tige de valve, et de réduire ainsi de manière substantielle la hauteur globale du dispositif. In the position illustrated in FIG. 3D, the annular member 22 has been raised from so as to be in contact with the lower end of the flexible sleeve 13. The dispensing head is thus ready to be mounted by snapping onto a container 2, the annular member fitting onto the valve stem 5. The different dimensions are calculated appropriately so that the flexible sleeve 13 is in slight compression so that sealing takes place at the interface between the sleeve 13 and the annular member 22. Thus, the realization of the means actuation with two axes of articulations perpendicular to the axis of the container allows, by folding, successive or simultaneous, around the two axes, to position the annular member 22 substantially at the level of the valve stem, and to reduce thus substantially the overall height of the device.

La figure 2 à laquelle il est maintenant fait référence, illustre une variante au mode de réalisation des figures 1A et 1B. Selon ce mode de réalisation, le manchon souple 13 est monté serré sur la tige de valve émergente. Le mouvement d'ouverture de la valve est transmis à la tige de valve par l'intermédiaire d'une portion 30, pliée sensiblement à l'équerre par rapport à la portion intermédiaire 20. De la même manière que pour le mode de réalisation des figures 1A et 1B, la force d'ouverture de la valve, est appliquée sensiblement au niveau de la tige de valve, par l'intermédiaire de la portion 30. Cette portion 30 fait basculer la tige de valve par l'intermédiaire du manchon souple 13. Avantageusement, on dispose un moyen de renfort 31 entre la partie intermédiaire 20 et la partie 30, de manière à maintenir un appui efficace entre la partie 30 et la tige de valve 5.FIG. 2, to which reference is now made, illustrates a variant of the mode. of embodiment of FIGS. 1A and 1B. According to this embodiment, the sleeve flexible 13 is mounted tight on the emerging valve stem. Movement valve opening is transmitted to the valve stem via a portion 30, folded substantially at right angles to the intermediate portion 20. In the same way as for the embodiment of FIGS. 1A and 1B, the valve opening force, is applied substantially at the level of the valve, by means of the portion 30. This portion 30 causes the rod to tilt valve via the flexible sleeve 13. Advantageously, there is a reinforcement means 31 between the intermediate part 20 and the part 30, so as to maintain effective support between part 30 and the valve stem 5.

Ainsi qu'il apparaít clairement dans ce mode de réalisation, en position montée du couvercle 12, le bord inférieur de celui-ci est disposé entre les deux butées 23 et 24, de sorte qu'il est impossible d'actionner la valve dans cette position fermée. La butée 24 empêche par ailleurs tout mouvement de dépliage de la partie intermédiaire 20. Les autres parties du dispositif de distribution et d'application sont conformes à ce qui a été décrit en référence aux figures 1A-1B et 3A-3D, et par conséquent, ne nécessitent aucune description supplémentaire.As it clearly appears in this embodiment, in the mounted position of the cover 12, the lower edge thereof is disposed between the two stops 23 and 24, so that it is impossible to actuate the valve in this closed position. The stop 24 also prevents any unfolding movement of the part intermediate 20. The other parts of the dispensing and application system comply with what has been described with reference to FIGS. 1A-1B and 3A-3D, and therefore, do not require any additional description.

On réalise ainsi, un dispositif de distribution et d'application dans lequel la fonction "application" et la fonction "ouverture de la valve" sont totalement déconnectées, et ce, sans augmenter de manière substantielle, ni le coût de revient, ni l'encombrement d'un tel dispositif. Par ailleurs, le nombre de pièces est inchangé. Un tel dispositif peut être utilisé avec toute la douceur et l'efficacité requises pour l'application d'un produit froid, traitant une zone très sensible du corps.This produces a distribution and application device in which the function "application" and the "valve opening" function are totally disconnected, and this, without substantially increasing, neither the cost price, nor the size of such a device. Furthermore, the number of pieces is unchanged. Such a device can be used with all the smoothness and efficiency required for the application of a cold product, treating a very sensitive area of the body.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après. A titre d'exemple, on pourrait prévoir un troisième axe au voisinage de l'organe de basculement de la tige, de manière à retarder légèrement le basculement de la tige par rapport à l'action de l'utilisatrice sur la zone d'appui des moyens d'actionnement. Ceci pourrait constituer une "sécurité" en évitant certains actionnements non intentionnels de la valve.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the spirit of the invention as claimed below. AT by way of example, a third axis could be provided in the vicinity of the tilting of the rod, so as to slightly delay the tilting of the rod relative to the action of the user on the support zone of the means actuation. This could constitute "security" by avoiding certain unintentional valve actuations.
