Description

La présente invention concerne une tête de distribution destinée à équiper un dispositif de conditionnement et de distribution d'un produit, notamment cosmétique ou dermatologique. Un tel produit peut être distribué notamment sous forme d'une crème, d'un gel, d'une mousse ou d'un spray.The present invention relates to a dispensing head intended to equip a device for packaging and distributing a product, in particular cosmetic or dermatological. Such a product can be distributed in particular as a cream, gel, foam or spray.

Généralement, une tête de distribution, telle que visée par la présente invention, est destinée à équiper un dispositif de conditionnement et de distribution qui comprend un réservoir contenant le produit à distribuer, pourvu d'une extrémité ouverte, sur laquelle est fixé un organe de distribution. Un tel organe de distribution peut être une pompe ou une valve qui est surmontée d'une tête de distribution. Une tête de distribution de ce type permet à l'utilisateur d'acheminer le produit sortant du réservoir vers un orifice de distribution. Elle peut en outre permettre de commander l'actionnement de l'organe de distribution, pour éjecter une dose de produit hors du réservoir.Generally, a distribution head, as referred to herein invention is intended to equip a packaging and distribution which comprises a reservoir containing the product to be distributed, provided an open end, on which is fixed a dispensing member. Such dispensing member may be a pump or a valve which is surmounted a distribution head. A distribution head of this type allows the user to convey the product leaving the reservoir towards a port of distribution. It can also make it possible to control the actuation of the dispensing member, for ejecting a dose of product from the reservoir.

Pour certaines utilisations nécessitant une application relativement précise, il est connu d'utiliser une tête de distribution équipant un récipient dans laquelle l'orifice de distribution est formé à l'extrémité d'un élément allongé tel qu'une canule.For certain uses requiring a relatively precise application, it is known to use a dispensing head fitted to a container in which the dispensing orifice is formed at the end of an elongated element such as a cannula.

Le brevet FR 2 594 808 décrit un exemple d'un distributeur de type aérosol comprenant un réservoir équipé d'une valve et surmonté d'une telle tête de distribution. La canule est en outre mobile et peut prendre deux positions de distribution différentes. Toutefois, il n'est pas prévu que la canule puisse prendre une position de fermeture.Patent FR 2,594,808 describes an example of an aerosol dispenser comprising a reservoir fitted with a valve and surmounted by such a head distribution. The cannula is also mobile and can take two positions of different distribution. However, it is not intended that the cannula could take a closed position.

Le brevet US 3,116,856 décrit également un exemple d'un distributeur du type aérosol comprenant un réservoir équipé d'une valve et surmonté d'une telle tête de distribution. Selon ce document, la tête de distribution comprend une première partie fixée sur le réservoir et une canule, mobile par rapport à cette première partie, entre une position de distribution et une position de fermeture. En position de distribution, c'est-à-dire lorsque l'orifice de distribution peut communiquer avec l'intérieur du réservoir en activant la valve, la canule est disposée selon un axe perpendiculaire à l'axe du récipient. En position de fermeture, c'est-à-dire lorsque l'orifice de distribution ne peut pas communiquer avec l'intérieur du réservoir, la canule se place le long de la paroi latérale du réservoir, selon un axe parallèle à l'axe du réservoir. Ainsi, pour passer de la position de distribution à la position de fermeture, l'utilisateur doit juste appuyer sur la canule selon un axe sensiblement parallèle à l'axe du récipient de manière à faire pivoter la canule autour d'un axe perpendiculaire à l'axe du récipient.US Patent 3,116,856 also describes an example of a dispenser of the type aerosol comprising a reservoir equipped with a valve and surmounted by such a head of distribution. According to this document, the distribution head includes a first part fixed on the reservoir and a cannula, movable relative to this first part, between a dispensing position and a closed position. In the dispensing position, i.e. when the dispensing orifice can communicate with the interior of the reservoir by activating the valve, the cannula is arranged along an axis perpendicular to the axis of the container. In position of closing, i.e. when the dispensing opening cannot communicate with the inside of the tank, the cannula is placed along the side wall of the tank, along an axis parallel to the axis of the tank. So, to go from the dispensing position to the closed position, the user just has to press on the cannula along an axis substantially parallel to the axis of the container so as to rotate the cannula around an axis perpendicular to the axis of the container.

L'invention a pour objet une nouvelle tête de distribution destinée à être montée sur un réservoir d'axe X qui comprend un premier élément muni d'un orifice de sortie intérieur apte à être en communication sélective avec l'intérieur du réservoir, et un second élément, traversé par un conduit qui débouche sur un orifice de distribution. Le second élément est apte à pivoter autour d'un axe Y oblique par rapport à l'axe X de manière à passer d'une position de fermeture dans laquelle le second élément obture l'orifice de sortie intérieur, à une position de distribution dans laquelle l'orifice de sortie intérieur est en communication, via le conduit, avec l'orifice de distribution. La tête de distribution est en outre configurée pour activer un organe de distribution prévu sur le réservoir, notamment une pompe ou une valve, de manière à mettre en communication l'orifice de sortie intérieur du premier élément avec l'intérieur du réservoir.The subject of the invention is a new dispensing head intended to be mounted on an X-axis reservoir which comprises a first element provided with a interior outlet capable of being in selective communication with the interior of the tank, and a second element, crossed by a conduit which leads to a dispensing orifice. The second element is able to pivot around a Y axis oblique to the X axis so as to pass from a closed position in which the second element blocks the interior outlet orifice, at a dispensing position in which the interior outlet is in communication, via the conduit, with the dispensing orifice. The head of distribution is further configured to activate a planned distribution member on the tank, in particular a pump or a valve, so as to communication the interior outlet of the first element with the interior of the tank.

Pour passer d'une position d'utilisation à une position de fermeture, il suffit ainsi de faire pivoter une partie de la tête de distribution autour d'un axe Y qui est oblique par rapport à l'axe X du réservoir.To move from a position of use to a closed position, it suffices to rotate part of the dispensing head around a Y axis which is oblique to the X axis of the tank.

Selon un exemple de réalisation, le second élément, c'est-à-dire la partie mobile de la tête de distribution, peut comprendre un organe de montage d'axe Y monté dans le premier élément de manière à pivoter autour de son axe Y. Le second élément peut en outre comprendre une canule, à savoir un élément allongé, traversée par une portion du conduit et qui débouche dans l'orifice de distribution. Du fait que l'orifice de distribution soit formé à l'extrémité d'un élément relativement allongé, la tête de distribution est capable de distribuer du produit de façon précise et directive.According to an exemplary embodiment, the second element, that is to say the part movable from the dispensing head, may include a shaft mounting member Y mounted in the first element so as to pivot around its Y axis. second element may further comprise a cannula, namely an element elongated, crossed by a portion of the conduit and which opens into the orifice of distribution. Because the dispensing orifice is formed at the end of a relatively elongated element, the dispensing head is capable of dispensing produces with precision and direction.

L'axe de la canule peut avantageusement former un angle non nul avec l'axe de l'organe de montage, notamment un angle d'environ 45°. Ainsi, la canule ne s'étend pas dans l'axe Y autour duquel elle pivote de sorte qu'il est relativement facile, grâce à sa forme allongée, de la saisir et de la faire pivoter autour de l'axe Y en la faisant décrire un mouvement circulaire autour de l'axe Y.The axis of the cannula can advantageously form a non-zero angle with the axis of the mounting member, in particular an angle of about 45 °. Thus, the cannula does not not extend in the Y axis around which it pivots so that it is relatively easy, thanks to its elongated shape, to grasp it and rotate it around the Y axis by making it describe a circular movement around the Y axis.

Selon un exemple particulier, l'axe Y forme un angle d'environ 45° avec l'axe X du réservoir.According to a particular example, the Y axis forms an angle of about 45 ° with the X axis of the tank.

La canule peut être en dehors de l'axe X en position de distribution de la tête de distribution. L'orifice de distribution qui se trouve à l'extrémité libre de la canule est ainsi relativement éloigné de l'axe du réservoir et donc de la main de l'utilisateur qui tient le réservoir. On évite ainsi que le produit qui sort par l'orifice de distribution ne vienne souiller les doigts de l'utilisateur.The cannula can be outside the X axis in the dispensing position of the head of distribution. The dispensing opening which is at the free end of the cannula is thus relatively distant from the axis of the reservoir and therefore from the hand of the user holding the tank. This avoids that the product that leaves through the orifice dispenser does not stain the user's fingers.

La canule peut être sensiblement dans l'axe X lorsqu'elle est en position de fermeture. Ainsi, dans cette position la canule n'augmente pas l'encombrement latéral du dispositif de conditionnement et de distribution qu'elle équipe.The cannula can be substantially in the X axis when it is in the position of closing. Thus, in this position the cannula does not increase the size side of the packaging and distribution device it equips.

Selon un mode de réalisation particulier de l'invention, l'organe de montage comprend une paroi latérale, notamment cylindrique de révolution, comportant au moins une ouverture, et est traversé par une seconde portion du conduit. L'organe de montage est monté pivotant dans une cavité formée dans le premier élément dans laquelle débouche l'orifice de sortie intérieur, ladite cavité et l'organe de montage ayant des formes complémentaires. L'organe de montage est monté dans la cavité de manière telle que, en position de fermeture de la tête de distribution, sa paroi latérale obture de manière étanche l'orifice de sortie intérieur et que, en position de distribution, l'ouverture est au moins en partie en regard de l'orifice de sortie intérieur.According to a particular embodiment of the invention, the mounting member comprises a side wall, in particular cylindrical of revolution, comprising at least one opening, and is crossed by a second portion of the conduit. The mounting member is pivotally mounted in a cavity formed in the first element into which the interior outlet orifice opens, said cavity and the mounting member having complementary shapes. The organ of mounting is mounted in the cavity in such a way that, in the position of closing the dispensing head, its side wall seals tightly the interior outlet and that, in the dispensing position, the opening is at less partially opposite the interior outlet.

L'organe de montage peut être maintenu dans le premier élément par frottement, ou encore par encliquetage, par exemple grâce à une saillie annulaire prévue sur la paroi extérieure de l'organe de montage et qui coopère avec une gorge annulaire prévue sur la paroi interne de la cavité, ou inversement.The mounting member can be held in the first element by friction, or even by snap-fastening, for example thanks to a projection annular provided on the outer wall of the mounting member and which cooperates with an annular groove provided on the internal wall of the cavity, or Conversely.

Le premier élément de la tête de distribution peut être directement monté sur le réservoir. Il comprend alors des moyens de fixation destinés à fixer ladite tête sur le réservoir, notamment par serrage, encliquetage ou vissage.The first element of the dispensing head can be directly mounted on the tank. It then comprises fixing means intended to fix said head. on the tank, in particular by tightening, snap-fastening or screwing.

Le second élément peut être obtenu de moulage d'une seule pièce d'un matériau thermoplastique. Le premier élément peut également être obtenu de moulage d'une seule pièce d'un matériau thermoplastique.The second element can be obtained from a single piece molding of a thermoplastic material. The first element can also be obtained from one-piece molding of a thermoplastic material.

L'invention concerne également un dispositif de conditionnement et de distribution d'un produit, notamment cosmétique comprenant un réservoir d'axe X et une tête de distribution telle que celle qui vient d'être décrite précédemment.The invention also relates to a device for packaging and distribution of a product, in particular a cosmetic, comprising an axis reservoir X and a distribution head such as the one just described previously.

La tête de distribution peut sensiblement ne pas déborder la plus grande section transversale S, selon un plan perpendiculaire à l'axe X, du réservoir lorsque le dispositif est observé dans l'axe X du réservoir et lorsque le second élément est en position de fermeture. Dans cette position de fermeture, le dispositif a un encombrement latéral peu important puisqu'il est simplement limité à l'encombrement du réservoir. Ainsi, un tel distributeur est relativement peu encombrant à stocker.The dispensing head may not significantly overflow the largest cross section S, along a plane perpendicular to the X axis, of the reservoir when the device is observed in the X axis of the tank and when the second element is in the closed position. In this closed position, the device has a small lateral dimension since it is simply limited to the size of the tank. So, such a distributor is relatively space-saving to store.

Lorsque le second élément est en position de distribution, la tête de distribution déborde la plus grande section transversale S, selon un plan perpendiculaire à l'axe X, du réservoir lorsque le dispositif est observé dans l'axe X du réservoir. When the second element is in the dispensing position, the dispensing head extends beyond the largest cross section S, along a plane perpendicular to the X axis of the reservoir when the device is observed in the X axis of the reservoir.

Le dispositif peut en outre comprendre un organe de distribution équipant le réservoir et pourvu d'un organe d'activation avec lequel est couplé le premier élément. L'organe de distribution est par exemple constitué d'une valve de type valve aérosol, ou encore d'une pompe à actionnement manuel. Ainsi, la tête de distribution et en particulier le premier élément sert également de bouton-poussoir pour commander l'actionnement de l'organe de distribution.The device may also include a distribution member equipping the reservoir and provided with an activation member with which the first is coupled element. The dispensing member is for example constituted by a valve of the type aerosol valve, or a manually operated pump. So the head of distribution and in particular the first element also serves as a push button to control the actuation of the dispensing member.

Le dispositif selon l'invention est particulièrement utile pour le conditionnement et la distribution d'un produit cosmétique, ou dermatologique, notamment sous forme d'une crème, d'une mousse, d'un gel ou d'un spray.The device according to the invention is particularly useful for packaging and the distribution of a cosmetic or dermatological product, in particular under form of a cream, foam, gel or spray.

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:
  • Figure 1 illustrates an elevational view of an embodiment of a device for packaging and dispensing a product surmounted by a dispensing head according to the invention;

On a représenté sur les figures 1 à 4B un exemple d'un dispositif 1 de conditionnement et de distribution équipé d'une tête de distribution 10 selon l'invention. There is shown in Figures 1 to 4B an example of a device 1 of packaging and distribution equipped with a distribution head 10 according to the invention.

Le dispositif 1 comprend un réservoir 20 d'axe X, réalisé par exemple en aluminium. Il est évident que tout autre matériau peut être utilisé pour réaliser le réservoir et en particulier du fer blanc ou du plastique. Le réservoir 20 comprend une paroi latérale 21, de forme générale cylindrique de section transversale S circulaire et constante sur la majeure partie de sa hauteur, fermée à une première extrémité par un fond 22. La seconde extrémité du réservoir comporte un épaulement 23 surmonté d'un col ouvert sur lequel est serti un organe de distribution 30.The device 1 comprises a reservoir 20 of axis X, produced for example in aluminum. It is obvious that any other material can be used to make the tank and in particular tinplate or plastic. The tank 20 comprises a side wall 21, of generally cylindrical section transverse S circular and constant over most of its height, closed at one end by a bottom 22. The second end of the tank has a shoulder 23 surmounted by an open neck on which is set with a distribution member 30.

L'organe de distribution 30, qui n'est pas représenté de façon détaillée sur les figures, est par exemple constitué d'une valve de type aérosol, le réservoir étant pressurisé. Une coupelle de montage 32, sertie sur le col ouvert du réservoir, supporte un organe d'activation 31. L'organe d'activation est une tige de valve qui peut être activée axialement, c'est-à-dire une valve à enfoncement, en réponse à une pression exercée dessus. Lorsque cesse la pression d'actionnement, un moyen de rappel, notamment un ressort, contraint la tige de valve en position de fermeture de la valve. La tige de valve est formée sensiblement dans l'axe X du réservoir et déborde axialement l'ouverture du réservoir. Alternativement, on peut utiliser une valve dont la tige de valve peut être activée latéralement, c'est-à-dire une valve à basculement.The distribution member 30, which is not shown in detail on the figures, for example consists of an aerosol type valve, the reservoir being pressurized. A mounting cup 32, set on the open neck of the reservoir, supports an activation member 31. The activation member is a rod valve which can be activated axially, i.e. a push-in valve, in response to pressure exerted on it. When the pressure stops actuation, a return means, in particular a spring, constrains the rod valve in valve closed position. The valve stem is formed substantially in the X axis of the tank and axially extends beyond the opening of the tank. Alternatively, a valve can be used, the valve stem of which can be activated laterally, i.e. a tilting valve.

En variante, on peut envisager d'utiliser un organe de distribution constitué d'une pompe. Dans ce cas, l'actionnement de la pompe se fait généralement par une pression exercée axialement qui provoque le déplacement axial d'un organe d'activation. L'organe d'activation est couplé à un piston dont le déplacement à l'intérieur du corps de pompe, dans un sens, provoque la sortie sous pression du produit, et dans l'autre sens, provoque l'aspiration du produit dans le corps de pompe. Généralement le piston est contraint dans sa position correspondant au volume maximal de la chambre de pompage au moyen d'un ressort.As a variant, it is possible to envisage using a distribution member constituted of a pump. In this case, the pump is usually actuated by an axially exerted pressure which causes the axial displacement of a activating organ. The activation member is coupled to a piston whose movement inside the pump body, in one direction, causes the output under product pressure, and in the other direction, causes product suction in the pump body. Generally the piston is constrained in its position corresponding to the maximum volume of the pumping chamber by means of a spring.

La tête de distribution 10, représentée de façon plus détaillée aux figures 3A et 3B, est formée essentiellement d'un premier élément 11 constituant un corps, prévu pour être monté sur le réservoir 20, et d'un second élément 12, mobile par rapport au corps 11.The dispensing head 10, shown in more detail in FIGS. 3A and 3B, is essentially formed of a first element 11 constituting a body, designed to be mounted on the tank 20, and a second element 12, mobile relative to the body 11.

Le corps 11 est obtenu de moulage d'une seule pièce d'un matériau thermoplastique, par exemple d'un polypropylène. Le corps comprend, dans sa partie inférieure, une jupe de montage 110 montée par serrage sur la coupelle 32 de l'organe de distribution de manière à solidariser la tête de distribution avec le réservoir. Avantageusement, la paroi intérieure de la jupe de montage comprend un premier décrochement 110a qui serre la coupelle et, sur au moins une partie de sa périphérie, un second décrochement 110b qui vient en butée sur la coupelle 32. Cette butée 110b permet de monter la tête de distribution sur le réservoir selon une position précise, notamment pour limiter l'enfoncement axial de la tête de distribution sur le réservoir et ainsi éviter d'activer la tige de valve lors du montage. En variante, la paroi intérieure de la jupe de montage peut comporter un godron, non représenté, qui vient s'encliqueter sous la coupelle 32, ou encore dans une gorge, non représentée prévue sur la paroi du réservoir 20. La jupe 110 coiffe la partie supérieure du réservoir au niveau de l'épaulement et présente une section transversale sensiblement égale à celle du reste du réservoir de sorte que la paroi extérieure de la jupe de montage constitue un prolongement de la paroi latérale du réservoir, sans débordement latéral.The body 11 is obtained by molding in one piece of a material thermoplastic, for example polypropylene. The body understands, in its lower part, a mounting skirt 110 mounted by clamping on the cup 32 of the dispensing member so as to secure the dispensing head with the tank. Advantageously, the inner wall of the mounting skirt includes a first step 110a which clamps the cup and, on at least part of its periphery, a second step 110b which abuts on the cup 32. This stop 110b makes it possible to mount the dispensing head on the tank in a precise position, in particular to limit the axial depression of the dispensing head on the reservoir and thus avoid activate the valve stem during assembly. Alternatively, the inner wall of the mounting skirt may include a godron, not shown, which comes snap under the cup 32, or into a groove, not shown provided on the wall of the tank 20. The skirt 110 covers the upper part of the reservoir at the shoulder and has a cross section substantially equal to that of the rest of the tank so that the wall outside of the mounting skirt is an extension of the side wall of the tank, without lateral overflow.

La partie supérieure du corps 11 de la tête de distribution constitue un bouton poussoir. Pour activer la tige de valve 31, la partie supérieure du corps 11 de la tête de distribution comprend un manchon 119 qui vient s'emmancher sur la tige de valve 31 avec laquelle il est couplé. Le manchon permet de transmettre à la tige de valve la pression exercée par un utilisateur sur la surface extérieure de la tête de distribution afin de l'enfoncer de manière à ouvrir la valve.The upper part of the body 11 of the dispensing head constitutes a button button. To activate the valve stem 31, the upper part of the body 11 of the dispensing head includes a sleeve 119 which is fitted onto the valve stem 31 with which it is coupled. The sleeve allows to transmit at the valve stem the pressure exerted by a user on the exterior surface of the dispensing head in order to push it in so as to open the valve.

Pour permettre l'actionnement de la tige de valve, la partie supérieure du corps peut être déplacée par rapport au réservoir, et donc par rapport à la jupe qui elle-même est fixe par rapport au réservoir. A cet effet, la partie supérieure du corps 11 est reliée à la jupe 110 par une paroi intermédiaire 111, cylindrique de révolution. Cette paroi intermédiaire 111 a un diamètre plus petit que le diamètre de la jupe de montage 110 et n'est pas montée de façon concentrique avec la jupe de montage 110. En effet, la paroi 111 est formée par un prolongement axial 112 d'une petite portion angulaire de la jupe de montage 110 alors que le bord inférieur 111 a du reste de la paroi 111 est libre. La portion angulaire 112 fait ainsi office de charnière et le bord libre 111a peut s'enfoncer à l'intérieur de la jupe de montage. Un rebord transversal 113 s'étend avantageusement radialement à partir de l'extrémité supérieure de la jupe de montage 110, qui n'est pas continue avec la paroi intermédiaire 111, pour ne laisser qu'une ouverture 114 juste suffisante pour permettre l'enfoncement du bouton-poussoir sans qu'une trop grande ouverture ne soit formée dans la tête de distribution.To allow actuation of the valve stem, the upper part of the body can be moved relative to the tank, and therefore relative to the skirt which itself is fixed relative to the reservoir. For this purpose, the upper part of the body 11 is connected to the skirt 110 by an intermediate wall 111, cylindrical of revolution. This intermediate wall 111 has a smaller diameter than the diameter of the mounting skirt 110 and is not mounted concentrically with the mounting skirt 110. In fact, the wall 111 is formed by a axial extension 112 of a small angular portion of the mounting skirt 110 while the lower edge 111a of the rest of the wall 111 is free. The angular portion 112 thus acts as a hinge and the free edge 111a can sink into the inside of the mounting skirt. A transverse ledge 113 advantageously extends radially from the upper end of the mounting skirt 110, which is not continuous with the intermediate wall 111, to leave only an opening 114 just sufficient to allow pushing in the push button without too large an opening formed in the dispensing head.

Pour recevoir l'élément mobile 12 de la tête de distribution, la partie supérieure du corps 12 comprend une cavité 117. La cavité 117 a un axe géométrique Y qui forme avec l'axe X du réservoir, un angle α environ égal à 45°. La cavité 117 est délimitée par une paroi latérale cylindrique 117a qui coupe l'axe X, et par un fond 117b. Une gorge annulaire 117c, dont la fonction sera détaillée par la suite, s'étend dans un plan perpendiculaire à l'axe Y dans la paroi latérale 117a, à l'opposé du fond 117b.To receive the movable element 12 of the dispensing head, the upper part of the body 12 comprises a cavity 117. The cavity 117 has a geometric axis Y which forms with the axis X of the reservoir, an angle α approximately equal to 45 °. The cavity 117 is delimited by a cylindrical side wall 117a which intersects the axis X, and by a bottom 117b. An annular groove 117c, the function of which will be detailed by thereafter, extends in a plane perpendicular to the Y axis in the side wall 117a, opposite the bottom 117b.

La cavité 117 est destinée à être mise en communication avec l'intérieur du réservoir. A cet effet, un canal 118, formé sensiblement dans l'axe X du réservoir, débouche à une première extrémité 118a dans la paroi latérale 117b de la cavité 117. La seconde extrémité 118b du canal 118 débouche dans le manchon 119 couplé à la tige de valve 31. Lorsque, en réponse à une pression exercée sur la tête de distribution le manchon enfonce la tige de valve, la valve s'ouvre mettant ainsi l'intérieur du réservoir en communication avec le canal 118.The cavity 117 is intended to be placed in communication with the interior of the tank. To this end, a channel 118, formed substantially in the X axis of the tank, opens at a first end 118a into the side wall 117b of the cavity 117. The second end 118b of the channel 118 opens into the sleeve 119 coupled to valve stem 31. When in response to pressure exerted on the dispensing head the sleeve pushes in the valve stem, the valve opens thus placing the interior of the tank in communication with the channel 118.

L'élément mobile 12 de la tête de distribution comprend un élément allongé 120 constitué par une canule, de forme extérieure sensiblement tronconique. La canule 120 est traversée par un premier conduit 121a qui débouche à une extrémité de la canule sur un orifice de distribution 122.The movable element 12 of the dispensing head comprises an elongated element 120 consisting of a cannula, of substantially frustoconical external shape. The cannula 120 is crossed by a first conduit 121a which leads to a end of the cannula on a dispensing orifice 122.

La canule est montée dans le corps 11 de la tête de distribution par un organe de montage 123 constitué par une paroi cylindrique de révolution formée à l'extrémité de la canule opposée à l'orifice de distribution 122. L'organe de montage 123 et la cavité 117 dans laquelle il vient s'insérer ont des formes sensiblement complémentaires. La paroi cylindrique 123 vient en effet en contact étanche avec la paroi de la cavité 117 tout en autorisant l'organe de montage à pivoter autour de l'axe Y. Un cordon annulaire 123a, formé sur la paroi extérieure de l'organe de montage, est prévu pour se loger dans la gorge annulaire 117c de la cavité de manière à maintenir l'élément mobile 12 en position dans le corps 11 de la tête, tout en autorisant, là encore, l'organe de montage à pivoter autour de l'axe Y. L'organe de montage est traversé par un second conduit 121b qui communique avec le premier conduit 121a qui traverse la canule. Une ouverture 124 est formée sur une portion angulaire de la paroi formant l'organe de montage 123, dans sa partie inférieure, l'ouverture pouvant venir en regard de l'orifice de sortie intérieur 118a défini par l'extrémité du canal 118 qui débouche dans la cavité 117. Ainsi, dans une première position de l'élément mobile 12, l'orifice de sortie intérieur 118a est en communication, via l'ouverture 124, avec le conduit 121 et donc avec l'orifice de distribution 122. Dans une seconde position de l'élément mobile 12, l'orifice de sortie intérieur 118a est obturé par la paroi 123 de l'organe de montage. Alternativement, on peut prévoir que le canal 118 débouche, non pas dans la paroi latérale de l'organe de montage, mais dans son fond, le fond étant alors partiellement ouvert de manière à obtenir une position de distribution et une position d'ouverture.The cannula is mounted in the body 11 of the dispensing head by a member mounting 123 constituted by a cylindrical wall of revolution formed at the end of the cannula opposite the dispensing orifice 122. The mounting 123 and the cavity 117 in which it is inserted have shapes appreciably complementary. The cylindrical wall 123 indeed comes in tight contact with the wall of the cavity 117 while allowing the member to mounting to pivot around the Y axis. An annular bead 123a, formed on the outer wall of the mounting member, is designed to be housed in the groove annular 117c of the cavity so as to maintain the movable element 12 in position in the body 11 of the head, while still allowing, again, the mounting to pivot around the Y axis. The mounting member is traversed by a second conduit 121b which communicates with the first conduit 121a which crosses the cannula. An opening 124 is formed on an angular portion of the wall forming the mounting member 123, in its lower part, the opening can come opposite the interior outlet orifice 118a defined by the end of channel 118 which opens into cavity 117. Thus, in a first position of the movable element 12, the interior outlet orifice 118a is in communication, via the opening 124, with the conduit 121 and therefore with the orifice of distribution 122. In a second position of the movable element 12, the orifice internal outlet 118a is closed by the wall 123 of the mounting member. Alternatively, provision can be made for the channel 118 to open, not in the side wall of the mounting member, but in its bottom, the bottom then being partially open so as to obtain a distribution position and a open position.

La canule 120 a un axe géométrique Z qui forme avec l'axe Y de l'organe de montage, dans un plan passant par l'ouverture 124, un angle β environ égal à 45° en se rapprochant de l'ouverture 124. Ainsi, en position de distribution, c'est-à-dire lorsque l'ouverture 124 est en regard de l'orifice de sortie intérieur 118a formé dans l'axe X du réservoir, la canule 120 est sensiblement perpendiculaire à l'axe X du réservoir. Lorsque la canule est sensiblement dans l'axe X du réservoir, l'ouverture 124 est en regard d'une zone de la paroi délimitant la cavité 117 diamétralement opposée à l'orifice de sortie intérieur 118a, de sorte que l'orifice de sortie intérieur 118a est en regard de la paroi 123 de l'organe de montage.The cannula 120 has a geometric axis Z which forms with the axis Y of the organ of mounting, in a plane passing through the opening 124, an angle β approximately equal to 45 ° by approaching the opening 124. Thus, in the dispensing position, that is to say when the opening 124 is opposite the interior outlet orifice 118a formed in the axis X of the reservoir, the cannula 120 is substantially perpendicular to the X axis of the tank. When the cannula is substantially in the axis X of the reservoir, the opening 124 is facing an area of the wall delimiting the cavity 117 diametrically opposite to the interior outlet orifice 118a, so that the interior outlet 118a faces the wall 123 of the mounting member.

Selon l'exemple de réalisation du dispositif décrit, la partie supérieure du corps 12 a une forme générale externe bombée, cette surface bombée étant coupée par deux surfaces sensiblement planes.According to the embodiment of the device described, the upper part of the body 12 has a generally curved external shape, this curved surface being cut by two substantially flat surfaces.

Une première surface plane 116 coupe en partie le dôme selon un axe oblique par rapport à l'axe X du réservoir, en particulier selon un axe perpendiculaire à l'axe Y. La cavité cylindrique 117 qui reçoit l'organe de montage de l'élément mobile 12, débouche sensiblement au centre de cette surface 116. De son côté, la canule 120 est entourée à sa base, c'est-à-dire du côté de l'organe de montage, d'une calotte hémisphérique 125 dont la base plane vient en appui sur la surface plane 116 du corps 12. La courbure de la calotte 125 est telle qu'elle continue la forme bombée de la partie supérieure du corps 12.A first planar surface 116 partially cuts the dome along an oblique axis with respect to the X axis of the tank, in particular along an axis perpendicular to the Y axis. The cylindrical cavity 117 which receives the element mounting member mobile 12, opens substantially at the center of this surface 116. From its side, the cannula 120 is surrounded at its base, that is to say on the side of the mounting, of a hemispherical cap 125 whose flat base comes to bear on the flat surface 116 of the body 12. The curvature of the cap 125 is such that it continues the convex shape of the upper part of the body 12.

La surface bombée de la partie supérieure du corps est également coupée par une seconde surface sensiblement plane 115, voire légèrement concave, qui coupe une autre partie du dôme dans un autre plan oblique par rapport à l'axe X du réservoir. Il s'agit d'une surface continue qui a pour fonction d'identifier la zone sur laquelle l'utilisateur peut appuyer pour enfoncer le bouton-poussoir.The curved surface of the upper body is also cut by a second substantially planar surface 115, even slightly concave, which cuts another part of the dome in another plane oblique to the axis Tank X. It is a continuous surface which has the function of identifying the area on which the user can press to press the push button.

En position de fermeture, la canule est sensiblement dans l'axe X du réservoir comme cela est représenté aux figures 3A et 4A et ne déborde donc pas la section transversale S du réservoir. Dans cette position de fermeture, on peut prévoir que la tête de distribution est recouverte d'un capuchon amovible, non représenté, qui interdit tout basculement de la canule.In the closed position, the cannula is substantially in the X axis of the reservoir as shown in Figures 3A and 4A and therefore does not extend beyond the cross section S of the tank. In this closed position, you can provide that the dispensing head is covered with a removable cap, not shown, which prohibits any tilting of the cannula.

Afin de faciliter l'utilisation du dispositif selon l'invention on peut repérer les deux positions que peut prendre l'élément mobile 12 et qui correspondent, d'une part, à la position de distribution et, d'autre part, à la position de fermeture. A cet effet, on peut par exemple prévoir une marque visuelle sur la surface bombée de la partie supérieure du corps avec laquelle peuvent être mises en regard successivement deux marques prévues sur la portion mobile 12. La mise en regard d'une première marque correspond alors à la position de distribution et la mise en regard d'une seconde marque correspond à la position de fermeture. Les marques peuvent être formées par exemple par des couleurs différentes ou encore des lettres différentes suffisamment explicites pour permettre à l'utilisateur d'identifier la position de distribution et la position de fermeture.In order to facilitate the use of the device according to the invention, it is possible to identify the two positions which the movable element 12 can take and which correspond, on the one hand, at the distribution position and, on the other hand, at the distribution position closing. For this purpose, one can for example provide a visual mark on the curved surface of the upper body with which can be successively compared two marks provided on the movable portion 12. The comparison of a first mark then corresponds to the position of distribution and comparison of a second brand corresponds to the position closing. The marks can be formed for example by colors different letters or different letters explicit enough to allow the user to identify the dispensing position and the closing.

Alternativement ou en complément, les deux positions peuvent être repérées mécaniquement. On peut en effet prévoir un picot sur la base plane de la calotte hémisphérique 125 qui coopère avec une gorge en arc de cercle formée sur la surface plane 116 de la partie supérieure du corps, les deux extrémités de l'arc de cercle de la gorge correspondant aux deux positions de la tête de distribution. Ainsi, lorsque l'élément mobile pivote autour de l'axe Y, le picot se déplace dans la gorge en arc de cercle et vient en butée aux deux extrémités de la gorge.Alternatively or in addition, the two positions can be identified mechanically. We can indeed provide a pin on the flat base of the hemispherical cap 125 which cooperates with a groove in an arc on the flat surface 116 of the upper part of the body, the two ends of the arc of the throat corresponding to the two positions of the head of distribution. Thus, when the movable element pivots about the Y axis, the pin is moves in the groove in an arc and abuts at both ends throat.

Pour utiliser le dispositif 1, l'utilisateur place la canule 120 selon un axe sensiblement perpendiculaire à l'axe X du réservoir en faisant pivoter l'ensemble de la partie mobile 12 autour de l'axe Y, le mouvement circulaire de la canule étant matérialisé par la flèche F sur la figure 3B. Dans cette position représentée aux figures 3B et 4B, l'orifice de sortie intérieur 118a est en communication avec l'orifice de distribution 122. En outre, dans cette position, la canule déborde latéralement la section transversale S du réservoir, comme on le voit à la figure 4B, de sorte que l'orifice de distribution 122 est relativement éloigné du réservoir et de la main de l'utilisateur lorsqu'il tient le dispositif pour appuyer sur le bouton-poussoir. L'utilisateur peut alors enfoncer le bouton-poussoir en appuyant sur la surface 115 afin d'enfoncer le manchon ainsi que la tige de valve, ce mouvement étant autorisé par le fait que la partie supérieure de la tête de distribution bascule autour de la charnière 112 et que le bord libre 111 a de la paroi intermédiaire 11 peut s'enfoncer à l'intérieur de la jupe de montage 110. La valve s'ouvre alors de manière à laisser sortir du réservoir le produit pressurisé contenu dans le réservoir. Le produit est ensuite distribué par l'orifice de distribution via le canal 118 et le conduit 121a et 121b.To use the device 1, the user places the cannula 120 along an axis substantially perpendicular to the X axis of the tank by rotating the entire mobile part 12 around the Y axis, the circular movement of the cannula being materialized by the arrow F in FIG. 3B. In this position shown in FIGS. 3B and 4B, the interior outlet orifice 118a is in communication with the dispensing orifice 122. In addition, in this position, the cannula laterally extends beyond the cross section S of the reservoir, as as seen in Figure 4B, so that the dispensing orifice 122 is relatively far from the tank and the user's hand when holding the device for pressing the push button. The user can then press the push button by pressing on the surface 115 in order to push in the sleeve as well as the valve stem, this movement being authorized by the fact that the part top of the dispensing head swings around the hinge 112 and that the free edge 111a of the intermediate wall 11 can sink inside the mounting skirt 110. The valve then opens so as to let out of the tank the pressurized product contained in the tank. The product is then distributed by the distribution orifice via the channel 118 and the conduit 121a and 121b.

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.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. It is obvious that there are variations be made without departing from the spirit of the invention as claimed below.
