Description

Tête de distribution de produit fluide et procédé de fabrication d'une telle tête Fluid product distribution head and method of manufacturing such a head

La présente invention concerne une tête de distribution de produit fluide destinée à être associée à, ou montée sur, un organe de distribution de produit fluide. L'invention concerne également un procédé de fabrication d'une telle tête de distribution. La tête de distribution comprend dans le cadre de la présente invention un corps définissant un canal de sortie pour le produit fluide, un gicleur définissant un orifice de distribution et une surcapsule montée sur le corps de manière à en masquer au moins une partie. Une telle tête de distribution peut être utilisée dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie. Le document FR 2 774367 décrit une telle tête de distribution comprenant un corps, un gicleur, et une surcapsule. Le corps est rapporté de manière fixe à rintérieur de la surcapsule. Le maintien du corps à l'intérieur de la surcapsule est assuré par les forces de frottement entre la paroi externe du corps et la paroi interne de la surcapsule. La surcapsule masque la paroi supérieure et la paroi périphérique du corps. Le gicleur est monté préalablement sur le corps avant l'engagement du corps dans la surcapsule, ou en variante, le gicleur est inséré dans le corps une fois que le corps est engagé dans la surcapsule. Dans les deux cas, la surcapsule comprend un fût définissant une fenêtre au niveau de laquelle est positionné l'orifice de distribution formé par le gicleur. Avec cette tête de distribution de l'art antérieur précité, le montage de la tête de distribution s'effectue en deux opérations de montage distinctes, à savoir le montage du gicleur sur le corps et le montage du corps dans la surcapsule. D'autre part, le montage du corps dans la surcapsule nécessite des tolérances très faibles afin d'assurer un bon maintien du corps dans la surcapsule. A l'inverse, l'engagement du corps dans la surcapsule doit pouvoir s'effectuer avec une force d'emmanchage raisonnable. C'est pourquoi, à la fois la surcapsule et le corps doivent être réalisés avec une grande précision, ce qui augmente les coûts de fabrication. Il en est de même en ce qui concerne le gicleur et le corps. Pour résoudre les problèmes précités de l'art antérieur, la tête de distribution de produit fluide de l'invention prévoit que la surcapsule est surmoulée sur le corps. Par surmoulage, on entend que le corps forme une partie du moule de la surcapsule. Ainsi, une partie de la surface externe de la matière plastique injectée dans le moule de la surcapsule va venir directement en contact intime avec le corps. Ce contact réahse une adhérence qui résulte en une fixation solide de la surcapsule sur le corps. Avec cette technique de surmoulage, on assure que la surcapsule suit de manière intime tout les contours et aspérités du corps. Avantageusement, le corps comprend une surface supérieure et une surface périphérique, la surcapsule est surmoulée sur la surface supérieure, et avantageusement aussi sur la surface périphérique. Dans certains cas, il peut être également être avantageux que la surcapsule soit surmoulée sur le gicleur préalablement monté sur le corps. Etant donné que la surcapsule n'est jamais en contact du produit fluide à distribuer, elle peut être réalisée en une matière plastique incompatible avec le produit fluide. Selon une autre caractéristique intéressante de l'invention, la surcapsule comprend un fut pourvu d'une fenêtre pour le passage du gicleur à monter sur le corps en l'engageant à travers la fenêtre. , ; Avantageusement, l'orifice de distribution est positionné dans la fenêtre. En variante, l'orifice de distribution est positionné en retrait de la fenêtre sensiblement au xtiveau d'une surface externe du corps. De préférence, la fenêtre présente une forme tronconique qui s'évase vers l'extérieur. La surface tronconique sert de cône de diffusion qui permet de canaliser le jet de produit fluide pulvérisé à travers l'orifice de distribution. Selon un autre aspect de l'invention, le corps comprend une jupe périphérique formant extérieurement la surface périphérique, ladite jupe étant pourvue d'une ouverture donnant sur un logement de réception pour le gicleur, ledit logement formant avantageusement un noyau autour duquel le gicleur est engagé en force. Selon une autre caractéristique, un élément intercalaire est disposé entre le corps et la surcapsule, ladite surcapsule étant réalisée en un matériau translucide ou transparent de sorte que l'élément intercalaire est visible à travers la surcapsule. Il est à noter que l'interposition de cet élément intercalaire entre le corps et la surcapsule peut être mise en œuvre sans que la surcapsule ne soit surmoulée sur le corps. La caractéristique liée à l'élément intercalaire peut donc être protégeable indépendamment. Selon une autre caractéristique, le gicleur fait saillie vers l' extérieur à partir de la surface périphérique. Grâce à cette technique de surmoulage, il est possible de réaliser la surcapsule alors que le gicleur est préalablement monté sur le corps. Ceci n'est pas possible avec la tête de distribution du document FR 2 774 367. La tête de distribution selon l'invention peut notamment servir de poussoir. Dans ce cas, la surcapsule peut définir une surface d'appui destinée à l'application d'une pression pour actionner l'organe de distribution. L'invention définit également un procédé de fabrication d'une tête de distribution de produit fluide destinée à être associée à un organe de distribution de produit fluide, ladite tète comprenant un corps définissant un canal de sortie pour le produit fluide, un gicleur définissant un orifice de distribution et une surcapsule montée sur le corps de manière à en masquer au moins une partie, ledit procédé comprenant successivement une première étape de surmoulage de la surcapsule sur le corps et une seconde étape de montage du gicleur sur le corps. En variante, l'invention peut également prévoir un procédé de fabrication d'une tête de distribution de produit fluide destinée à être associée à un organe de distribution de produit fluide, ladite tête comprenant un corps définissant un canal de sortie pour le produit fluide, un gicleur définissant un orifice de distribution et une surcapsule montée sur le corps de manière à en masquer au moins une partie, le procédé comprenant successivement une première étape de montage du gicleur sur le corps et une seconde étape de surmoulage de la surcapsule sur le corps, et éventuellement sur le gideur. Avantageusement, un élément intercalaire peut être disposé entre le corps et la surcapsule, ladite surcapsule étant réahsée en un matériau transparent ou translucide. Ceci est valable pour les deux variantes de procédés de fabrication. L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemples non limitatifs plusieurs modes de réalisation de l'invention. Sur les figures : la figure 1 est une vue en coupe transversale verticale à travers un corps équipé d'un gideur selon un premier mode de réalisation, la figure 2 est une vue similaire à celle de la figure 1 avec une surcapsule surmoulée sur le corps de la figure 1, la figure 3 est vue en coupe transversale verticale à travers une tête de distribution selon un second mode de réalisation de l'invention, la figure 4 est une vue en coupe transversale verticale à travers un corps et un gicleur selon un troisième mode de réalisation, la figure 5 est une vue similaire à celle de la figure 4 avec une surcapsule surmoulée sur le corps de la figure 4, la figure 6 est une vue en coupe transversale verticale à travers un corps et un gicleur selon un quatrième mode de réalisation de l'invention, et la figure 7 est une vue similaire à celle de la figure 6 avec une surcapsule surmoulée sur le corps de la figure 6. Dans tous les modes de réalisation représentés sur les figures, la tête de distribution comprend trois éléments constitutifs, à savoir un corps 1, un gicleur 2 ou 2' et une surcapsule 3. Il n'est cependant pas exclu que le corps et le gicleur soient réalisés de manière monobloc ou d'une manière équivalente. Le corps 1 est identique dans tous les modes de réalisation des figures. Cependant, on peut prévoir d'autres formes pour le corps 1. Dans le cas des figures, il s'agit d'un corps conçu pour former une tête de distribution du type poussoir sur lequel on appuie à l'aide d'un doigt pour actionner l'organe de distribution qui peut être une pompe ou une valve. On peut toutefois imaginer que le corps soit destiné à être assodé à un organe de distribution (pompe ou valve) de manière totalement dissociée du poussoir d'actionnement. Dans ce cas, le corps 1 est destiné à être monté de manière fixe par rapport au corps de la pompe ou de la valve et au réservoir. Ainsi, sur les figures, le corps de poussoir 1 peut être du type standard réahse en une matière plastique injedée moulée qui est compatible avec le produit fluide à distribuer. Ced s'explique du fait que le produit fluide vient en contart de la matière constitutive du corps 1. Le corps comprend un plateau supérieur 11 qui définit une surface supérieure externe 111. Le corps comprend également une jupe périphérique 12 qui définit une surface externe périphérique 121. La surface supérieure 111 se raccorde sur son bord périphérique extérieur de manière avantageusement arrondie à la surface périphérique sensiblement ou parfaitement cylindrique 121. Le plateau 11 et la jupe 12 définissent ainsi une forme de godet renversé. Le corps forme intérieurement en dessous du plateau 111 un manchon de raccordement 13 et un logement de réception 14. Le manchon 13 définit un conduit interne de sortie 131 à travers lequel le produit fluide refoulé par la pompe ou la valve s'écoule dans le logement 14 à travers un petit canal de liaison 134. Le logement 14, plus visible sur la figure 3, définit une ouverture 142 au niveau de la jupe périphérique 12. Le logement 14 contient un noyau 141 formé de manière monobloc par le corps 1. Le noyau définit extérieurement un annulaire de réception pour le gideur 2 ou 2' comme on le verra d-après. Il s'agit là d'une conception tout à fait classique pour un corps de poussoir standard. Le gideur 2 ou 2', suivant les modes de réalisation, comprend une douille de base 20 de forme sensiblement cylindrique et obturée à une de ses extrémités par une paroi de distribution. Cette paroi de distribution est traversée par un orifice de distribution 21 qui peut être du type pulvérisateur ou non. Une partie de la douille 20 définit une couronne de fixation 24 destinée à venir en prise dans le logement annulaire formé autour du noyau 141. Optionnellement, comme représenté sur les figures 1, 2 et 3, le gicleur peut comprend une pièce de remplissage 23. Cette pièce 23 peut coopérer avec la paroi de distribution de manière à former un système de tourbillonnement, dassiquement constitué de canaux de tourbillomiement radiaux débouchant dans une chambre de tourbillonnement centrale centrée sur l'orifice de distribution 21. En l'absence de pièce de remplissage 23, c'est la surface frontale du noyau 141 qui coopère avec la paroi de distribution pour former le système de tourbillonnement 22. A vrai dire, la conception particulière du gideur 2 ou 2' n'est pas critique pour la présente invention. Il suffit que le gicleur coopère avec le corps pour remplir sa fondion de pulvérisation du produit fluide. Dans la forme de réalisation du gideur 2 des figures 1, 2 et 3, le gicleur fait saillie vers l'extérieur à partir de la surface périphérique 121 du corps. On peut également dire que l'orifice de distribution 21 est projeté radialement vers l'extérieur par rapport à la surface périphérique 121. En revanche, dans le mode de réalisation du gicleur 2' des figures 4 à 7, l'orifice de distribution 21 est sensiblement aligné avec la surface périphérique 121. On peut également dire que le gicleur est inscrit dans le logement formé par le corps. On peut également imaginer des formes de réalisation dans lesquels l'orifice de distribution est situé en retrait à l'intérieur du logement formé par le corps de sorte que l'orifice est décalé vers rintérieur par rapport à la surface périphérique 121. On peut également noter que le gicleur 2 ou 2' est monté par engagement latéral ou radial dans le logement 14 par rapport à l'axe X représenté sur la figure 4. La surcapsule 3 est montée sur le corps 1 en venant en contact d'une partie ou de la totalité de la surface supérieure 111 et de la surface périphériqueThe present invention relates to a fluid dispenser head intended to be associated with, or mounted on, a fluid dispenser member. The invention also relates to a method of manufacturing such a dispensing head. The dispensing head comprises, within the framework of the present invention, a body defining an outlet channel for the fluid product, a nozzle defining a dispensing orifice and an over-cap mounted on the body so as to mask at least part of it. Such a dispensing head can be used in the fields of perfumery, cosmetics or even pharmacy. Document FR 2 774367 describes such a dispensing head comprising a body, a nozzle, and an overcap. The body is fixedly attached to the interior of the overcap. The maintenance of the body inside the over-cap is ensured by the friction forces between the external wall of the body and the internal wall of the over-cap. The overcaps mask the upper wall and the peripheral wall of the body. The nozzle is previously mounted on the body before the body is engaged in the overcap, or alternatively, the nozzle is inserted into the body once the body is engaged in the overcap. In both cases, the over-cap comprises a barrel defining a window at the level of which is positioned the dispensing orifice formed by the nozzle. With this dispensing head of the aforementioned prior art, the mounting of the dispensing head is carried out in two separate mounting operations, namely the mounting of the nozzle on the body and the mounting of the body in the overcap. On the other hand, mounting the body in the overcap requires very small tolerances in order to ensure good support of the body in the overcap. Conversely, the engagement of the body in the overcap must be able to be carried out with a reasonable grip force. This is why both the overcap and the body must be produced with great precision, which increases the manufacturing costs. The same applies to the nozzle and the body. To solve the aforementioned problems of the prior art, the fluid dispenser head of the invention provides that the overcap is overmolded on the body. By overmolding is meant that the body forms part of the mold of the overcap. Thus, part of the external surface of the plastic material injected into the mold of the overcap will come directly into intimate contact with the body. This contact reaffirms an adhesion which results in a solid fixation of the overcap on the body. With this overmolding technique, we ensure that the overcap follows intimately all the contours and roughness of the body. Advantageously, the body comprises an upper surface and a peripheral surface, the overcap is overmolded on the upper surface, and advantageously also on the peripheral surface. In some cases, it may also be advantageous for the overcap to be overmolded on the nozzle previously mounted on the body. Since the overcap is never in contact with the fluid to be dispensed, it can be made of a plastic material incompatible with the fluid. According to another advantageous characteristic of the invention, the over-cap comprises a barrel provided with a window for the passage of the nozzle to be mounted on the body by engaging it through the window. , ; Advantageously, the dispensing orifice is positioned in the window. Alternatively, the dispensing orifice is positioned set back from the window substantially at the level of an external surface of the body. Preferably, the window has a frustoconical shape which widens outwards. The frustoconical surface serves as a diffusion cone which makes it possible to channel the jet of sprayed fluid product through the dispensing orifice. According to another aspect of the invention, the body comprises a peripheral skirt externally forming the peripheral surface, said skirt being provided with an opening giving onto a housing for receiving the nozzle, said housing advantageously forming a core around which the nozzle is committed in force. According to another characteristic, an intermediate element is disposed between the body and the over-cap, said over-cap being made of a material translucent or transparent so that the insert is visible through the overcap. It should be noted that the interposition of this intermediate element between the body and the over-cap can be implemented without the over-cap being molded onto the body. The characteristic linked to the intermediate element can therefore be protected independently. According to another characteristic, the nozzle projects outward from the peripheral surface. Thanks to this overmolding technique, it is possible to produce the overcap while the nozzle is previously mounted on the body. This is not possible with the dispensing head of document FR 2 774 367. The dispensing head according to the invention can in particular serve as a pusher. In this case, the overcap can define a bearing surface intended for the application of pressure to actuate the dispensing member. The invention also defines a method of manufacturing a fluid dispenser head intended to be associated with a fluid dispenser member, said head comprising a body defining an outlet channel for the fluid product, a nozzle defining a dispensing orifice and an over-cap mounted on the body so as to mask at least a part of it, said method successively comprising a first step of overmolding the over-cap on the body and a second step of mounting the nozzle on the body. As a variant, the invention may also provide a method for manufacturing a fluid product distribution head intended to be associated with a fluid product distribution member, said head comprising a body defining an outlet channel for the fluid product, a nozzle defining a dispensing orifice and an over-cap mounted on the body so as to mask at least a part of it, the method successively comprising a first step of mounting the nozzle on the body and a second step of overmolding the over-cap on the body , and possibly on the nozzle. Advantageously, an intermediate element can be disposed between the body and the over-cap, said over-cap being re-formed in a transparent or translucent material. This applies to both variants of the manufacturing process. The invention will now be described more fully with reference to the accompanying drawings which give, by way of nonlimiting examples, several embodiments of the invention. In the figures: FIG. 1 is a view in vertical transverse section through a body equipped with a nozzle according to a first embodiment, FIG. 2 is a view similar to that of FIG. 1 with an overcapsule overmolded on the body of Figure 1, Figure 3 is a vertical cross-sectional view through a dispensing head according to a second embodiment of the invention, Figure 4 is a vertical cross-sectional view through a body and a nozzle according to a third embodiment, Figure 5 is a view similar to that of Figure 4 with an over-molded overmold on the body of Figure 4, Figure 6 is a vertical cross-sectional view through a body and a nozzle according to a fourth embodiment of the invention, and FIG. 7 is a view similar to that of FIG. 6 with an overmold encapsulated on the body of FIG. 6. In all the embodiments represented in the figures, the he dispensing head comprises three constituent elements, namely a body 1, a nozzle 2 or 2 'and an overcap 3. It is not however excluded that the body and the nozzle are produced in a single piece or in an equivalent manner . The body 1 is identical in all the embodiments of the figures. However, other forms can be provided for the body 1. In the case of the figures, it is a body designed to form a dispensing head of the pusher type, which is pressed with a finger. to actuate the dispensing member which can be a pump or a valve. One can however imagine that the body is intended to be associated with a distribution member (pump or valve) completely dissociated from the actuator. In this case, the body 1 is intended to be fixedly mounted relative to the body of the pump or of the valve and to the reservoir. Thus, in the figures, the pusher body 1 can be of the standard type reheated in a molded injected plastic which is compatible with the fluid to be dispensed. Ced is explained by the fact that the fluid product comes in contart from the material constituting the body 1. The body comprises an upper plate 11 which defines an external upper surface 111. The body also comprises a peripheral skirt 12 which defines a peripheral external surface 121. The upper surface 111 is connected on its outer peripheral edge advantageously rounded to the substantially or perfectly cylindrical peripheral surface 121. The plate 11 and the skirt 12 thus define an inverted cup shape. The body internally forms below the plate 111 a connection sleeve 13 and a receiving housing 14. The sleeve 13 defines an internal outlet conduit 131 through which the fluid product discharged by the pump or the valve flows into the housing 14 through a small connecting channel 134. The housing 14, more visible in FIG. 3, defines an opening 142 at the peripheral skirt 12. The housing 14 contains a core 141 formed integrally by the body 1. The nucleus externally defines an annular reception for the 2 or 2 'nozzle as will be seen below. This is a completely classic design for a standard pusher body. The nozzle 2 or 2 ', according to the embodiments, comprises a base sleeve 20 of substantially cylindrical shape and closed at one of its ends by a distribution wall. This distribution wall is traversed by a distribution orifice 21 which may or may not be of the sprayer type. A part of the sleeve 20 defines a fixing ring 24 intended to come into engagement in the annular housing formed around the core 141. Optionally, as shown in FIGS. 1, 2 and 3, the nozzle can comprise a filling part 23. This part 23 can cooperate with the distribution wall so as to form a swirl system, basically made up of radial swirl channels opening into a central vortex centered on the dispensing orifice 21. In the absence of a filling part 23, it is the front surface of the core 141 which cooperates with the dispensing wall to form the vortex system 22. In fact, the particular design of the nozzle 2 or 2 'is not critical to the present invention. It is sufficient for the nozzle to cooperate with the body to fill its spraying foundation with the fluid product. In the embodiment of the nozzle 2 of Figures 1, 2 and 3, the nozzle protrudes outward from the peripheral surface 121 of the body. It could also be said that the dispensing orifice 21 is projected radially outward relative to the peripheral surface 121. On the other hand, in the embodiment of the nozzle 2 'in FIGS. 4 to 7, the dispensing orifice 21 is substantially aligned with the peripheral surface 121. It can also be said that the nozzle is inscribed in the housing formed by the body. One can also imagine embodiments in which the dispensing orifice is set back inside the housing formed by the body so that the orifice is offset inwards relative to the peripheral surface 121. It is also possible note that the nozzle 2 or 2 ′ is mounted by lateral or radial engagement in the housing 14 relative to the axis X shown in FIG. 4. The overcap 3 is mounted on the body 1 by coming into contact with a part or of the whole of the upper surface 111 and of the peripheral surface

121. Toutefois, la surcapsule peut dans certains cas de réalisation venir en contad d'une partie ou de la totalité de la surface supérieure 111, en laissant la surface périphérique 121 visible ou démasquée. La surcapsule 3 masque ainsi la majeure partie de la surface externe du corps 1 en laissant toutefois sa face inférieure ouverte et dégagée de manière à pouvoir monter la tête de distribution sur un organe de distribution telle qu'une pompe ou une valve. En effet, le manchon de raccordement 13 doit rester accessible. La surcapsule 3 comprend une paroi d'appui 31 formant une surface extérieure d'appui 312. D'autre part, la surcapsule 3 comprend un fût périphérique sensiblement cylindrique 32 qui entoure la jupe 12 du corps 1. La paroi d'appui 31 comprend une surface intérieure 311 qui vient en contad time avec la surface supérieure 111 du plateau 11. D'autre part, le fût 32 forme une surface interne 321 qui vient avantageusement en contad intime avec la surface périphérique extérieure 121 de la jupe 12. Le fût 32 est également traversé par une fenêtre 322 qui fait communiquer l'extérieur du fût avec l'intérieur du fût. Cette fenêtre 322 est destinée au passage ou à la réception du gicleur 2 ou 2', suivant les modes de réalisation, comme on le .verra d-après. La surcapsule 3 peut également venir en contad intime avec le gicleur 2 au niveau de la fenêtre 322, comme on peut le voir sur la figure 2. Dans un autre mode de réalisation représenté sur les figures 5 et 7, la fenêtre 322 peut être réalisée avec une forme tronconique 323 qui s'évase vers l'extérieur. Bien entendu, la fenêtre 322 doit être positionnée de manière alignée avec le logement 14 du corps 1 destiné à recevoir le gicleur 2 ou 2'. La surcapsule 3 peut être réahsée en une matière plastique esthétique qui peut éventuellement être incompatible avec le produit fluide à distribuer. Elle peut également être réahse en matière transparente ou dans une matière offrant un contad de toucher soyeux ou caoutchouteux. Selon l'invention, la surcapsule 3 est surmoulée sur le corps 1, et avantageusement également sur le gicleur 2. Cela signifie que la surcapsule 3 est diredement moulée sur le corps et/ou le gicleur 2. Cette technique permet d'obtenir un contact intime entre les surfaces de la surcapsule et du corps et/ou gideur. Dans le premier mode de réalisation des figures 1 et 2, le gicleur 2 est préalablement engagé radialement dans son logement 14 formé par le corps 1. A l'état monté, l'orifice de distribution 21 du gideur fait saillie vers l'extérieur par rapport à la jupe 12. Ensuite, la surcapsule 3 est surmoulée sur le corps 1 ainsi que sur le gicleur 2. Le surmoulage de la surcapsule permet de maintenir définitivement le gicleur 2 sur le corps 1. On obtient ainsi une tête composite parfaitement unitaire et indémontable : c'est la surcapsule qui réahse la cohésion de l'ensemble de la tête. On peut noter que l'orifice de distribution 21 est situé dans la fenêtre 322 qui entoure de manière intime le gicleur 2. Plus précisément, le gicleur 21 est situé à proximité de la surface externe du fût 32 de la surcapsule 3. Dans le second mode de réalisation de la figure 3, la surcapsule 3 est d'abord surmoulée sur le corps 1. Une broche centrée sur le logement 14 permet de réaliser la fenêtre 322 dans la surcapsule 3. Une opération ultérieure de montage consiste à engager le gicleur 2 à travers la fenêtre 322 jusqu 'à ce qu'il vienne en prise définitive de montage dans le logement 14 du corps 1. En position finale, la tête de distribution se présente sous la forme représentée sur la figure 2. Toutefois, il n'y a pas de contad intime d'adhésion entre la surcapsule 3 et le gideur 2. Dans le troisième mode de réalisation des figures 4 et 5, le gicleur 2' est préalablement monté sur le corps 1. Toutefois, l'orifice de distribution 21 ne fait pas saillie hors du corps, mais reste aligné avec la jupe 12. Une opération ultérieure de moulage consiste à surmouler la surcapsule 3 sur le corps 1 avec le gicleur 2' préalablement monté. Une broche centrée sur le gicleur 2' permet de réaliser une fenêtre tronconique 322 dont la paroi tronconique 323 sert de cône de diffusion pour le jet de produit pulvérisé. Dans le quatrième mode de réalisation des figures 6 et 7, le corps 1 et le gideur 2' peuvent être identique à ceux de la figure 4, c'est-à-dire avec le gicleur 2' préalablement monté sur le corps 1. Toutefois, dans ce mode de réalisation, un élément intercalaire 4 est disposé sur la surface supérieure 111 du corps 1. Cet élément intercalaire 4 peut être simplement déposé ou encore fixé sur le corps 1.121. However, the overcapsule may in certain embodiments come in contad of part or all of the upper surface 111, leaving the peripheral surface 121 visible or unmasked. The overcap 3 thus masks the major part of the external surface of the body 1, however leaving its lower face open and free so as to be able to mount the dispensing head on a dispensing member such as a pump or a valve. In fact, the connection sleeve 13 must remain accessible. The overcap 3 comprises a support wall 31 forming an external support surface 312. On the other hand, the overcap 3 includes a substantially cylindrical peripheral barrel 32 which surrounds the skirt 12 of the body 1. The support wall 31 comprises an inner surface 311 which comes in contad time with the upper surface 111 of the plate 11. On the other hand, the barrel 32 forms an internal surface 321 which advantageously comes into intimate contad with the external peripheral surface 121 of the skirt 12. The barrel 32 is also crossed by a window 322 which communicates the outside of the barrel with the inside of the barrel. This window 322 is intended for the passage or reception of the nozzle 2 or 2 ′, according to the embodiments, as will be seen below. The overcap 3 can also come in close contact with the nozzle 2 at the level of the window 322, as can be seen in FIG. 2. In another embodiment shown in FIGS. 5 and 7, the window 322 can be produced with a frustoconical shape 323 which flares outwards. Of course, the window 322 must be positioned in alignment with the housing 14 of the body 1 intended to receive the nozzle 2 or 2 '. The overcap 3 can be reahsée in an aesthetic plastic material which may possibly be incompatible with the fluid product to be dispensed. It can also be re-sheathed in transparent material or in a material offering a contad of silky or rubbery feel. According to the invention, the over-cap 3 is molded onto the body 1, and advantageously also onto the nozzle 2. This means that the over-cap 3 is directly molded onto the body and / or the nozzle 2. This technique makes it possible to obtain a contact intimate between the surfaces of the overcap and the body and / or gideur. In the first embodiment of Figures 1 and 2, the nozzle 2 is previously engaged radially in its housing 14 formed by the body 1. In the assembled state, the dispensing orifice 21 of the nozzle protrudes outwardly relative to the skirt 12. Then, the over-cap 3 is overmolded on the body 1 as well as on the nozzle 2. The overmolding of the over-cap makes it possible to permanently maintain the nozzle 2 on the body 1. This gives a perfectly unitary composite head and cannot be dismantled: it is the overcap which reheats the cohesion of the whole head. It may be noted that the dispensing orifice 21 is located in the window 322 which intimately surrounds the nozzle 2. More precisely, the nozzle 21 is located near the external surface of the barrel 32 of the overcap 3. In the second embodiment of FIG. 3, the overcap 3 is first molded onto the body 1. A pin centered on the housing 14 makes it possible to make the window 322 in the overcap 3. A subsequent mounting operation consists in engaging the nozzle 2 through the window 322 until it comes into final mounting in the housing 14 of the body 1. In the final position, the dispensing head is in the form shown in FIG. 2. However, there is no intimate adhesion contad between the overcap 3 and the nozzle 2. In the third embodiment of FIGS. 4 and 5, the nozzle 2 ′ is previously mounted on the body 1. However, the orifice distribution 21 does not protrude from the body, but remains aligned with the skirt 12. A subsequent molding operation consists of overmolding the overcap 3 on the body 1 with the nozzle 2 'previously mounted. A spindle centered on the nozzle 2 'makes it possible to produce a frustoconical window 322 whose frustoconical wall 323 serves as a diffusion cone for the jet of sprayed product. In the fourth embodiment of Figures 6 and 7, the body 1 and the nozzle 2 'may be identical to those of Figure 4, that is to say with the nozzle 2' previously mounted on the body 1. However , in this embodiment, an intermediate element 4 is arranged on the upper surface 111 of the body 1. This intermediate element 4 can be simply deposited or even fixed on the body 1.

On peut même prévoir de surmouler le corps 1 sur l'élément intercalaire 4. Cet élément intercalaire 4 peut remplir une fonction esthétique ou décorative. Bien que l'élément 4 est représenté sur la surface supérieure 111, on peut également imaginer qu'il s'étend aussi ou uniquement sur la surface périphérique 121. Une opération ultérieure de moulage consiste à surmouler la surcapsule 3 sur le corpsOne can even provide for overmolding the body 1 on the intermediate element 4. This intermediate element 4 can fulfill an aesthetic or decorative function. Although the element 4 is shown on the upper surface 111, it can also be imagined that it also or only extends over the peripheral surface 121. A subsequent molding operation consists in overmolding the overcap 3 on the body

1 et sur l'élément intercalaire 4. L'élément intercalaire 4 est ainsi intercalé entre le corps 1 et la surcapsule 3. De préférence, dans ce cas, la surcapsule 3 est réalisée en un matériau transparent ou transludde de manière à laisser l'élément intercalaire 4 visible à travers la surcapsule 3. Autrement, la surcapsule 3 peut être identique à celle de la figure 5 c'est-à-dire avec une fenêtre tronconique 322. H est à noter que l'interposition d'un élément intercalaire avantageusement esthétique ou décoratif peut être mise en œuvre avec une surcapsule rapportée ou fixée de manière quelconque sur le corps, sans qu'il soit obhgatoirement nécessaire que la surcapsule 3 soit surmoulée sur le corps 1. On peut notamment imaginer que la surcapsule 3 soit seulement rapportée en force sur le corps 1, comme le document de l'art antérieur FR 2 774 367. Le terme « surmoulage » est un équivalent des termes « comoulage » ou « bi-injection ». Il signifie généralement qu'un élément, en roccurrence la surcapsule, est moulée sur un autre élément, à savoir le corps et/ou le gideur. Grâce à cette technique de surmoulage, on élimine tous défauts de tolérance au niveau du corps 1 et de la surcapsule 3. En outre, on élimine une opération de montage et on améliore également la fixation du gideur 2 sur le corps 1. 1 and on the intermediate element 4. The intermediate element 4 is thus interposed between the body 1 and the overcap 3. Preferably, in this case, the overcap 3 is made of a transparent or translucent material so as to leave the intermediate element 4 visible through the over-cap 3. Otherwise, the over-cap 3 may be identical to that of FIG. 5, that is to say with a frustoconical window 322. It should be noted that the interposition of an advantageously aesthetic or decorative intermediate element can be implemented with an added over-cap or fixed in any manner on the body, without it being necessarily necessary for the over-cap 3 to be overmolded on the body 1. One can in particular imagine that the overcap 3 is only brought into force on the body 1, like the document of the prior art FR 2 774 367. The term “overmolding” is an equivalent of the terms “co-molding” or “bi -injection ”. It generally means that an element, in this case the overcap, is molded on another element, namely the body and / or the nozzle. Thanks to this overmolding technique, all tolerance defects are eliminated at the level of the body 1 and of the overcapsule 3. In addition, an assembly operation is eliminated and the fixing of the nozzle 2 on the body 1 is also improved.
