Description

Tête de distribution de produit fluide et dispositif incorporant une telle tête. Fluid dispensing head and device incorporating such a head.
La présente invention concerne une tête de distribution destinée à être montée sur ou associée à un réservoir de produit fluide. L'invention concerne également un dispositif de distribution incorporant une telle tête.The present invention relates to a dispensing head intended to be mounted on or associated with a fluid reservoir. The invention also relates to a dispensing device incorporating such a head.
La présente invention a pour domaines d'application privilégiés mais non exclusifs la cosmétique, la parfumerie et la pharmaceutique.The present invention has preferred but not exclusive fields of application for cosmetics, perfumery and pharmaceuticals.
Les dispositifs de distribution de produit fluide de l'art antérieur comprennent en général un récipient rempli de produit fluide, tel qu'une crème, une lotion, un parfum etc, et un organe de distribution, tel qu'une pompe ou une valve, monté sur un col formé par le récipient. Cet organe est apte à prélever le produit fluide contenu dans ledit récipient suite à un actionnement manuel exercé par un utilisateur sur un poussoir. Le montage de cet organe est habituellement assuré au moyen d'une bague de fixation, généralement réalisée en matériau plastique. Une frette d'habillage peut en outre être prévue de manière à recouvrir au moins partiellement cette bague dans un but esthétique et/ou de blocage de la bague sur le col du récipient. De façon plus précise, l'organe de distribution comporte généralement un corps de pompe dans lequel coulisse un piston selon des mouvements de va et vient. Ce piston est généralement solidaire d'une tige d' actionnement déplaçable axialement par appui sur le poussoir. Cette tige d' actionnement définit bien souvent intérieurement un conduit dans lequel le produit fluide peut s'écouler. Ce conduit est alors mis en communication fluidique avec un canal de distribution ménagé dans le poussoir. Ce canal de distribution débouche alors dans un orifice de distribution assurant la sortie du produit fluide. Toutefois, il est à noter que l'actionnement de l'organe de distribution peut être effectué par un poussoir distinct, ne définissant pas de canal de distribution ni d'orifice de distribution. Un tel poussoir est dans ce cas alors uniquement dédié à l'actionnement de l'organe de distribution et ne participe donc pas à l'acheminement du produit fluide en tant que tel. L'orifice de distribution peut donc être soit mobile, c'est-à-dire se déplacer simultanément aux mouvements du poussoir, soit fixe, c'est-à-dire rester en permanence stationnaire en étant ainsi indépendant de la course d' actionnement du poussoir. Généralement, l'orifice de distribution est formé par un gicleur. Un tel gicleur peut donc être qualifié de gicleur mobile ou fixe.Fluid dispensing devices of the prior art generally comprise a container filled with fluid, such as cream, lotion, perfume, etc., and a dispensing member, such as a pump or a valve, mounted on a neck formed by the container. This member is adapted to collect the fluid contained in said container following manual actuation exerted by a user on a pusher. The mounting of this body is usually provided by means of a fixing ring, usually made of plastic material. A trim band may also be provided so as to cover at least partially this ring for aesthetic purposes and / or locking the ring on the neck of the container. More specifically, the dispensing member generally comprises a pump body in which slides a piston in reciprocating movements. This piston is generally integral with an actuating rod axially movable by pressing on the pusher. This actuating rod often defines internally a conduit in which the fluid can flow. This conduit is then placed in fluid communication with a distribution channel formed in the pusher. This distribution channel then opens into a dispensing orifice ensuring the output of the fluid product. However, it should be noted that the actuation of the dispenser member may be performed by a separate pusher, not defining a distribution channel or dispensing orifice. Such a pusher is in this case only dedicated to the actuation of the dispenser member and therefore does not participate in the delivery of the fluid as such. The dispensing orifice can therefore be either mobile, that is to say move simultaneously to the movements of the pusher, or is fixed, that is to say remain permanently stationary and thus be independent of the actuating stroke pusher. Generally, the orifice of distribution is formed by a nozzle. Such a nozzle can be described as mobile or fixed jet.
Le document FR 2 843 639 divulgue un ensemble de distribution de produit fluide intégrant un gicleur fixe. Dans ce cas, la tige d'actionnement solidaire du poussoir se déplace axialement alors que le gicleur reste en permanence dans une position figée. Les déplacements axiaux en va et vient de la tige sont alors compensés par un tube flexible reliant la tige d'actionnement au gicleur. Plus précisément, la tige est pourvue d'un manchon de raccordement et le gicleur est supporté par un porte-gicleur. Le tube flexible relie le manchon au porte-gicleur. Le tube comprend à cet effet deux parties de connexion en prise avec le manchon et le porte-gicleur. Il est alors prévu dans ce cas que les parties de connexion sont toutes deux positionnées latéralement, de préférence d'un même côté par rapport au manchon de raccordement et au porte-gicleur. Le tube flexible s'étend alors dans la tête de distribution de manière à s'écarter d'un plan passant par la tige d'actionnement et le gicleur fixe. Une telle structure est particulièrement appropriée pour des têtes de distribution présentant une section transversale oblongue ou ellipsoïdale.The document FR 2 843 639 discloses a fluid dispenser assembly incorporating a fixed nozzle. In this case, the actuating rod integral with the pusher moves axially while the nozzle remains permanently in a fixed position. The axial movements back and forth from the rod are then compensated by a flexible tube connecting the actuating rod to the nozzle. More specifically, the rod is provided with a connecting sleeve and the nozzle is supported by a nozzle holder. The flexible tube connects the sleeve to the nozzle holder. The tube comprises for this purpose two connection parts engaged with the sleeve and the nozzle holder. It is then provided in this case that the connecting parts are both positioned laterally, preferably on the same side with respect to the connecting sleeve and the nozzle holder. The flexible tube then extends into the dispensing head so as to deviate from a plane passing through the actuating rod and the fixed nozzle. Such a structure is particularly suitable for dispensing heads having an oblong or ellipsoidal cross section.
Un premier inconvénient lié à ce type de dispositif est qu'un tel tube flexible, qui fait saillie radialement vers l'extérieur par rapport au plan passant par la tige d'actionnement et le gicleur fixe, n'est absolument pas compatible avec des têtes de distribution présentant une configuration plus compacte ou allongée, tel qu'une configuration cubique, sphérique, cylindrique, etc. En effet, dans un tel cas, il n'y a pas assez de place dans la tête pour permettre au tube de s'étendre latéralement. On ne peut pas le réaliser plus court, car il doit assurer un accompagnement de la descente de la tige d'actionnement ce qui serait alors à l'origine d'une forte tension créée au niveau des extrémités du tube se connectant sur le porte-gicleur et sur la tige d'actionnement.A first drawback related to this type of device is that such a flexible tube, which protrudes radially outwards with respect to the plane passing through the actuating rod and the fixed nozzle, is absolutely not compatible with heads. dispenser having a more compact or elongated configuration, such as a cubic configuration, spherical, cylindrical, etc. Indeed, in such a case, there is not enough room in the head to allow the tube to extend laterally. It can not be made shorter, because it must provide support for the descent of the actuating rod which would then be at the origin of a high voltage created at the ends of the tube connecting to the holder. nozzle and on the actuating rod.
Un autre inconvénient lié à ce type de dispositif est la difficulté d'assemblage, puisque de tels moyens de raccordement ne peuvent être réalisés de façon monobloc et nécessitent ainsi un préassemblage du tuyau sur le manchon de raccordement et sur le porte-gicleur avant d'être positionnées sur leurs structures d'accueils correspondantes. Ainsi, la mise en place de tels moyens de raccordement s'avère particulièrement difficile et peu compatible avec une industrialisation à grande échelle.Another disadvantage related to this type of device is the difficulty of assembly, since such connection means can not be made in one piece and thus require a pre-assembly of the pipe on the connection sleeve and on the nozzle holder before be positioned on their corresponding reception structures. Thus, the establishment of such connection means turns out particularly difficult and hardly compatible with large-scale industrialization.
La présente invention a donc pour but de définir une tête de distribution de produit fluide surmontant les inconvénients précités de l'art antérieur. Plus particulièrement, la présente invention a pour but de définir une tête de distribution de produit fluide à spray fixe plus facile à produire, à assembler et à coût de revient moindre.The present invention therefore aims to define a fluid dispensing head overcoming the aforementioned drawbacks of the prior art. More particularly, the present invention aims to define a fixed spray fluid dispenser head easier to produce, assemble and lower cost.
Un but de la présente invention est encore de définir une tête de distribution de dimension restreinte et de forme compacte pourvue d'un gicleur fixe. Pour atteindre ces buts, la présente invention propose une tête de distribution de produit fluide destinée à être montée sur un réservoir de produit fluide comprenant un organe de distribution, tel qu'une pompe, destiné à prélever le produit fluide contenu dans ledit réservoir, ledit organe de distribution comprenant un corps et une tige d'actionnement déplaçable axialement dans ledit corps, un poussoir déplaçable axialement pour actionner le déplacement de la tige d'actionnement, un orifice de distribution par lequel le produit fluide est distribué à chaque actionnement de l'organe de distribution, ledit orifice étant monté de manière fixe par rapport au corps et au réservoir, un tube de raccordement flexible, reliant la tige d'actionnement à l'orifice de distribution, ledit tube comprenant une première extrémité de connexion solidaire de la tige d'actionnement et une seconde extrémité de connexion solidaire de l'orifice de distribution, la première extrémité s'étendant sensiblement parallèlement à la tige d'actionnement. Avantageusement, la première extrémité s'étend sensiblement dans le prolongement axial de la tige d'actionnement. Ainsi, le tube souple ou flexible ne part plus latéralement à partir de la tige d'actionnement comme c'est le cas dans le document FR 2 843 639, mais verticalement au-dessus de la tige d'actionnement. Cela permet de réaliser des têtes de distribution à spray fixe dont la configuration générale est plus élancée ou plus haute. En effet, lorsque la tête est étroite et haute, il n'y a pas de place dans la tête autour de la tige d'actionnement. En revanche, il y a de la place au-dessus de la tige d'actionnement. La première extrémité peut être axialement décalée par rapport à la tige tout en restant sensiblement parallèle. La première extrémité peut former un angle par rapport à l'axe de la tige, mais cet angle doit rester faible, de l'ordre de 20°. Selon un autre aspect de l'invention, la seconde extrémité de connexion s'étend sensiblement parallèlement à la première extrémité de connexion. La seconde extrémité peut faire un angle par rapport à la première extrémité, mais cet angle doit rester faible. Avantageusement, ladite tige d'actionnement, lesdites première et seconde extrémités de connexion et l'orifice de distribution s'étendent dans un même plan. Cela implique pratiquement que le tube flexible s'étend dans un plan vertical axial, et qu'il reste dans ce plan, même lors du déplacement de la tige d'actionnement. Le tube se déforme en un endroit qui n'est pas situé au niveau de ses extrémités de connexion. Le tube forme avantageusement une boucle en U, et c'est la partie courbée de la boucle qui se déforme, les extrémités des branches se déplaçant axialement sans déformation. Par conséquent, la configuration et la disposition du tube flexible selon l'invention sont particulièrement bien adaptées aux têtes ayant une course de tige importante.An object of the present invention is still to define a narrow size distribution head and compact shape provided with a fixed nozzle. To achieve these objects, the present invention proposes a fluid dispenser head intended to be mounted on a fluid reservoir comprising a dispensing member, such as a pump, for taking the fluid product contained in said reservoir, said dispensing member comprising a body and an actuating rod axially displaceable in said body, an axially displaceable pusher for actuating the displacement of the actuating rod, a dispensing orifice through which the fluid product is dispensed at each actuation of the dispenser member, said orifice being fixedly mounted relative to the body and the reservoir, a flexible connecting tube connecting the actuating rod to the dispensing orifice, said tube comprising a first connection end secured to the stem; actuator and a second connection end secured to the dispensing orifice, the first end being mite extending substantially parallel to the actuating rod. Advantageously, the first end extends substantially in the axial extension of the actuating rod. Thus, the flexible tube or flexible no longer laterally from the actuating rod as is the case in FR 2,843,639, but vertically above the actuating rod. This allows for fixed spray dispensing heads whose overall configuration is slender or higher. Indeed, when the head is narrow and high, there is no room in the head around the actuating rod. On the other hand, there is room above the actuating rod. The first end may be axially offset relative to the rod while remaining substantially parallel. The first end may form an angle relative to the axis of the rod, but this angle must remain low, of the order of 20 °. According to another aspect of the invention, the second connection end extends substantially parallel to the first connection end. The second end may be at an angle to the first end, but this angle must remain small. Advantageously, said actuating rod, said first and second connection ends and the dispensing orifice extend in the same plane. This practically implies that the flexible tube extends in an axial vertical plane, and that it remains in this plane, even during the displacement of the actuating rod. The tube deforms at a location that is not located at its connecting ends. The tube advantageously forms a U-shaped loop, and it is the curved portion of the loop that deforms, the ends of the branches moving axially without deformation. Therefore, the configuration and arrangement of the flexible tube according to the invention are particularly well suited to heads having a large rod stroke.
Selon une autre caractéristique de l'invention, la première extrémité de connexion est pourvue d'un manchon de raccordement raccordé à la tige d'actionnement et la seconde extrémité est pourvue d'un porte-gicleur recevant un gicleur formant l'orifice de distribution, le porte-gicleur étant monté fixement par rapport au corps et au réservoir. Le porte-gicleur est un type de partie de distribution au niveau de laquelle le produit fluide est distribué. La partie de distribution est pourvue ou non d'un gicleur. Avantageusement, le manchon de raccordement et la partie de distribution sont réalisés monobloc avec le tube de raccordement flexible. L'orientation axiale de la première extrémité de connexion du tube reliée au manchon permet de réaliser l'ensemble par moulage de matière plastique en utilisant une broche rectiligne qui s'étend à partir du manchon et qui forme le conduit du tube. La broche de moulage s'étend jusqu'au porte-gicleur.According to another characteristic of the invention, the first connection end is provided with a connection sleeve connected to the actuating rod and the second end is provided with a nozzle holder receiving a nozzle forming the dispensing orifice. , the nozzle holder being fixedly mounted relative to the body and the tank. The nozzle holder is a type of dispensing part at which the fluid product is dispensed. The dispensing portion is provided with or without a nozzle. Advantageously, the connecting sleeve and the dispensing portion are made in one piece with the flexible connecting tube. The axial orientation of the first connection end of the tube connected to the sleeve allows for the assembly by plastic molding using a straight pin which extends from the sleeve and which forms the conduit of the tube. The molding pin extends to the nozzle holder.
Avantageusement, lesdites première et seconde extrémités de connexion s'étendent respectivement au-dessus du manchon de raccordement et de la partie de distribution.Advantageously, said first and second connection ends respectively extend above the connection sleeve and the distribution part.
Avantageusement, l'orifice de distribution se situe à une hauteur axiale sensiblement identique à la hauteur axiale à laquelle se situe la tige d'actionnement en position de repos. En variante, l'orifice de distribution se situe à une hauteur axiale inférieure à la hauteur axiale à laquelle se situe la tige d'actionnement en position de repos. Cela est possible du fait que la seconde extrémité reliée au porte-gicleur s'étend verticalement parallèlement à l'axe de la tige d'actionnement, et n'occupe ainsi que très peu de place dans la tête, la déformation du tube se produisant au niveau de sa partie coudée.Advantageously, the dispensing orifice is located at an axial height substantially identical to the axial height at which the actuating rod is located in the rest position. Alternatively, the dispensing orifice is at an axial height less than the axial height at which the actuating rod is located in the rest position. This is possible because the second end connected to the nozzle holder extends vertically parallel to the axis of the actuating rod, and thus occupies very little space in the head, the deformation of the tube occurring. at its bent part.
L'invention définit également un distributeur de produit fluide comprenant une tête de distribution de produit fluide telle que définie ci-dessus associée à un réservoir de produit fluide.The invention also defines a fluid dispenser comprising a fluid dispensing head as defined above associated with a fluid reservoir.
L'invention sera plus amplement décrite en référence aux dessins joints, donnant à titre d'exemple non limitatif un mode de réalisation de l'invention. Sur les figures : la figure 1 est une vue éclatée en perspective d'une tête de distribution selon l'invention, la figure 2 est une vue en section transversale longitudinale d'une tête de distribution selon l'invention montée sur un réservoir de produit fluide, ladite tête étant en position de repos, et la figure 3 est une vue en section transversale longitudinale identique à la figure 2 d'une tête en position d'actionnement.The invention will be more fully described with reference to the accompanying drawings, giving by way of non-limiting example an embodiment of the invention. In the figures: FIG. 1 is an exploded perspective view of a dispensing head according to the invention; FIG. 2 is a longitudinal cross-sectional view of a dispensing head according to the invention mounted on a product reservoir; fluid, said head being in the rest position, and Figure 3 is a longitudinal cross-sectional view similar to Figure 2 of a head in the actuating position.
La tête de distribution selon l'invention est destinée à être associée à un réservoir de produit fluide (visible sur les figures 2 et 3). Cette tête de distribution forme ensemble avec le réservoir de produit fluide un dispositif de distribution de produit fluide. En référence à la figure 1, cette tête de distribution comporte un organe de distribution 1, une bague de fixation 2, une frette d'habillage 3, un insert 4, un embout 5 et un poussoir 7.The dispensing head according to the invention is intended to be associated with a fluid reservoir (visible in Figures 2 and 3). This dispensing head together with the fluid reservoir form a fluid dispensing device. With reference to FIG. 1, this dispensing head comprises a dispensing member 1, a fixing ring 2, a trim band 3, an insert 4, a tip 5 and a pusher 7.
L'organe de distribution 1 peut être une pompe ou une valve conventionnelle. En prenant l'exemple d'une pompe, l'organe de distribution 1 comporte un corps de pompe 10 dans lequel est montée une tige d'actionnement 11. Cette tige d'actionnement 11 est généralement solidaire d'un piston (non représenté) apte à coulisser de manière étanche par frottement dans ledit corps de pompe. Cette tige, ce piston et ce corps de pompe définissent ensemble une chambre de pompe, pourvue de clapets d'entrée et de sortie. Selon l'exemple de réalisation fourni, la tige d'actionnement définit intérieurement un canal par lequel du produit fluide peut s'écouler suite à la descente de la tige, ensemble avec le piston, dans le corps de pompe. Le piston et la tige peuvent ensuite être ramenés en position de repos sous l'action d'un ressort de rappel (non représenté), généralement disposé dans le corps de pompe 10. Ce type d'organe de distribution est tout à fait conventionnel, et n'est absolument pas critique pour la présente invention. Tel que visible sur les figures 2 et 3, l'organe de distribution 2 est fixé sur un col C d'un réservoir R au moyen de la bague de fixation 2. Cette bague de fixation peut être une bague à sertir, à visser ou, tel que représenté, à encliqueter. Le mode de fixation de l'organe de distribution sur un réservoir n'étant pas critique pour la présente invention, cette fixation ne sera pas davantage détaillée. La frette d'habillage 3 peut être réalisée en matériau plastique, ou en matériau métallique. Cette frette peut présenter toute configuration appropriée telle qu'une configuration parallélépipédique, cubique, sphérique, ovoïdale, etc. La frette 3 comporte dans le cas présent quatre parois : une paroi avant 30, une paroi arrière 32 et deux parois latérales 31, 33 reliant les parois avant et arrière. Ces parois comportent chacune une face externe et une face interne. La paroi avant 30 est traversée par une ouverture de distribution 300 reliant ainsi la lace interne à la face externe de la paroi avant. La frette entoure la bague 2 et bloque ainsi la bague sur le col. La frette, outre cette fonction de blocage, a une autre fonction plus esthétique en s 'étendant vers le haut de manière à créer un espace interne qui va servir à loger l'insert 4, l'embout 5, le poussoir obturant cet espace interne.The dispensing member 1 may be a pump or a conventional valve. Taking the example of a pump, the dispensing member 1 comprises a pump body 10 in which is mounted an actuating rod 11. This actuating rod 11 is generally integral with a piston (not shown) adapted to slide in a sealed manner by friction in said pump body. This rod, this piston and this pump body together define a pump chamber provided with inlet and outlet valves. According to the exemplary embodiment provided, the actuating rod internally defines a channel through which fluid can flow following the descent of the rod, together with the piston, into the body of pump. The piston and the rod can then be returned to the rest position under the action of a return spring (not shown), generally disposed in the pump body 10. This type of dispensing member is quite conventional, and is absolutely not critical for the present invention. As shown in Figures 2 and 3, the dispensing member 2 is fixed on a neck C of a tank R by means of the fixing ring 2. This fixing ring may be a crimp ring, screw or as shown, snap-fit. The method of attachment of the dispensing member on a reservoir is not critical for the present invention, this attachment will not be further detailed. The trim band 3 may be made of plastic material or metal material. This hoop may have any suitable configuration such as a parallelepipedal configuration, cubic, spherical, ovoid, etc. The hoop 3 comprises in this case four walls: a front wall 30, a rear wall 32 and two side walls 31, 33 connecting the front and rear walls. These walls each comprise an outer face and an inner face. The front wall 30 is traversed by a dispensing opening 300 thus connecting the inner lace to the outer face of the front wall. The hoop surrounds the ring 2 and thus locks the ring on the neck. The hoop, in addition to this locking function, has another more aesthetic function by extending upwardly so as to create an internal space that will be used to house the insert 4, the tip 5, the pusher closing this internal space .
L'insert 4 est une pièce à géométrie complexe comportant tel que représenté sur la figure 1, un cadre 40, une colonne de guidage 41 et une colonne de positionnement 42.The insert 4 is a piece with a complex geometry comprising as shown in FIG. 1, a frame 40, a guide column 41 and a positioning column 42.
Le cadre 40 peut présenter toute forme appropriée. Selon l'exemple représenté, ce cadre est de forme rectangulaire. Ce cadre forme un châssis à partir duquel s'étendent vers le bas ou vers le haut diverses parties constitutives de cet insert.The frame 40 may have any suitable shape. According to the example shown, this frame is rectangular. This frame forms a frame from which extend downward or upward various constituent parts of this insert.
Les colonnes de guidage 41, au nombre de deux, s'étendent vers le haut à partir du cadre 40. Ces deux colonnes de guidage s'étendent dans ce cas sensiblement en vis-à-vis sur les deux largeurs respectives du cadre 40 de l'insert. Dans cet exemple de réalisation, ces colonnes comportent chacune une fente de guidage 410. Le rôle de ces fentes sera expliqué par la suite. Ces colonnes de guidage occupent dans cet exemple une position sensiblement médiane au niveau des largeurs du cadre 40. Les colonnes de positionnement 42 s'étendent vers le haut à partir du cadre 40, sensiblement plus en avant par rapport aux colonnes de guidage 41. Ces colonnes de positionnement, également situées en vis-à-vis, s'étendent à partir de deux coins adjacents du cadre 40. Ces colonnes présentent dans le cas représenté une configuration de cornières en forme de L. Tel que visible sur la figure 1, ces colonnes comportent chacune une rainure de positionnement 420 dont la fonction sera ci-après décrite.The guide columns 41, two in number, extend upwards from the frame 40. These two guide columns extend in this case substantially in facing relation to the two respective widths of the frame 40 of FIG. the insert. In this embodiment, these columns each comprise a guide slot 410. The role of these slots will be explained later. In this example, these guide columns occupy a substantially median position at the widths of the frame 40. The positioning columns 42 extend upwardly from the frame 40, substantially further forward with respect to the guide columns 41. These positioning columns, also located opposite one another, extend from two adjacent corners of the frame 40. These columns have in the case shown a configuration of L-shaped angles. As visible in Figure 1, these columns each comprise a positioning groove 420 whose function will be described below.
Tel que visible sur les figures 2 et 3, cet insert 4 est monté dans la frette 3 et peut être maintenu en position dans cette frette par tous moyens appropriés. Selon l'exemple de réalisation de la figure 1, l'embout 5 comporte différentes parties constitutives, à savoir une partie frontale 50, une partie de distribution 51, un tube de raccordement flexible 52, un manchon de raccordement 53 et une partie de guidage et de transmission de poussée 54.As can be seen in FIGS. 2 and 3, this insert 4 is mounted in the band 3 and can be held in position in this band by any appropriate means. According to the embodiment of Figure 1, the nozzle 5 comprises different component parts, namely a front portion 50, a distribution portion 51, a flexible connecting tube 52, a connecting sleeve 53 and a guide portion and thrust transmission 54.
La partie frontale 50 présente selon le mode de réalisation représenté sur la figure 1 une configuration sensiblement parallélépipédique rectangulaire. Ce parallélépipède rectangle définit deux largeurs à partir desquelles s'étendent de façon légèrement décalée deux barrettes de coulissement 500. Cette pièce frontale définit une ouverture de montage 501 pour un gicleur 6.The front portion 50 has according to the embodiment shown in Figure 1 a substantially parallelepiped rectangular configuration. This rectangular parallelepiped defines two widths from which extend slightly slidably two sliding bars 500. This front part defines a mounting opening 501 for a nozzle 6.
La partie de distribution 51 se présente ici sous la forme d'un porte-gicleur associé à un gicleur 6. Le porte-gicleur 51 s'étend vers l'arrière à partir de ladite pièce frontale 50. Ce porte-gicleur forme une pièce sensiblement cylindrique située dans le prolongement de l'ouverture de montage 501. Ce porte-gicleur peut définir avec le gicleur 6 mis en place un système de tourbillonnement comportant des canaux de tourbillonnement et une chambre de tourbillonnement débouchant sur un orifice de distribution 60 formé par le gicleur 6. Le porte-gicleur et le gicleur définissent un axe de distribution qui est ici perpendiculaire à l'axe de déplacement de la tige.The distribution portion 51 is here in the form of a nozzle holder associated with a nozzle 6. The nozzle holder 51 extends rearwardly from said front piece 50. This nozzle holder forms a part substantially cylindrical located in the extension of the mounting opening 501. This nozzle holder can define with the nozzle 6 set up a swirl system comprising swirl channels and a swirl chamber opening on a dispensing orifice 60 formed by the nozzle 6. The nozzle holder and nozzle define a distribution axis which is here perpendicular to the axis of movement of the rod.
A la place du porte-gicleur, la partie de distribution peut se présenter sous la forme d'une simple sortie de distribution (sans gicleur). Le tube de raccordement flexible 52 relie respectivement, via une première extrémité de connexion 521 et une seconde extrémité de connexion 522, le manchon de raccordement 53 au porte-gicleur 51. La partie de guidage et de transmission de poussée 54 s'étend de part et d'autre du manchon de raccordement 53. Cette partie 54 comporte deux ailettes de guidage 540 et une plate-forme d'appui 541.Instead of the nozzle holder, the dispensing part can be in the form of a simple dispensing outlet (without nozzle). The flexible connecting tube 52 connects, via a first connection end 521 and a second connection end 522 respectively, the connecting sleeve 53 to the nozzle holder 51. The guide portion and thrust transmission 54 extends on either side of the connecting sleeve 53. This portion 54 comprises two guide vanes 540 and a support platform 541.
L'embout 5 est destiné à être fixé d'une part sur la tige d'actionnement 11 par connexion (par exemple par emmanchement) du manchon de raccordement 53 sur l'extrémité libre de la tige d'actionnement 11 et d'autre part à l'insert 4 par engagement des barrettes 500 dans les rainures 420. Lorsque l'embout 5 est mis en place sur l'insert 4, l'ouverture de montage 501 et donc l'orifice de distribution du gicleur se situent en vis-à-vis de l'ouverture de distribution 300 de la fierté. Le manchon de raccordement 53 et l'extrémité de connexion 521 du tube 52 s'étendent axialement, de préférence verticalement dans le prolongement de la tige d'actionnement dans cette position de montage. On peut également envisager que l'extrémité 521 soit décalée axialement par rapport à la tige, tout en restant parallèle. On peut toutefois envisager que l'extrémité 521 s'étende légèrement hors de l'axe. Selon l'invention, dans cette position de montage, les première et seconde extrémités de connexion 521 et 522 du tube de raccordement 52 s'étendent dans un plan confondu avec le plan défini par la tige d'actionnement 11 et l'orifice de distribution (gicleur). Ce plan est le plan de coupe des figures 2 et 3.The tip 5 is intended to be fixed on the one hand on the actuating rod 11 by connection (for example by fitting) of the connecting sleeve 53 on the free end of the actuating rod 11 and secondly to the insert 4 by engaging the bars 500 in the grooves 420. When the nozzle 5 is placed on the insert 4, the mounting opening 501 and therefore the dispensing orifice of the nozzle are located in with respect to the distribution opening 300 of the pride. The connecting sleeve 53 and the connecting end 521 of the tube 52 extend axially, preferably vertically in the extension of the actuating rod in this mounting position. One can also consider that the end 521 is axially offset relative to the rod, while remaining parallel. It can however be envisaged that the end 521 extends slightly off the axis. According to the invention, in this mounting position, the first and second connection ends 521 and 522 of the connecting tube 52 extend in a plane coinciding with the plane defined by the actuating rod 11 and the dispensing orifice. (nozzle). This plane is the sectional plane of Figures 2 and 3.
Tel que visible sur les figures, le tube de raccordement 52 présente une forme de U ou de fer à cheval. Ce tube s'étend de préférence complètement dans le plan défini par la tige 11 et l'ouverture de distribution 300. Ainsi, dans ce cas, les première et seconde extrémités 521, 522 du tube 52 et le tube 52 en son entier se positionnent au-dessus du manchon de raccordement et du porte-gicleur, et non latéralement tel que l'enseigne l'art antérieur, formant alors une arche surplombant la tige 11 et le gicleur 6. Un tel tube met alors en communication fluidique ladite tigeAs shown in the figures, the connecting tube 52 has a U-shape or horseshoe. This tube preferably extends completely in the plane defined by the rod 11 and the dispensing opening 300. Thus, in this case, the first and second ends 521, 522 of the tube 52 and the tube 52 as a whole are positioned. above the connection sleeve and the nozzle holder, and not laterally as taught in the prior art, then forming an arch overhanging the rod 11 and the nozzle 6. Such a tube then in fluid communication with said rod
11 et ledit gicleur 6 sans préoccupation de l'espace existant de part et d'autre de ces deux éléments. La seconde extrémité 522 s'étend avantageusement également sensiblement axialement, c'est-à-dire sensiblement parallèlement à la première extrémité 521. La seconde extrémité est sensiblement perpendiculaire à l'axe de distribution du gicleur. Selon une autre caractéristique avantageuse, le gicleur11 and said nozzle 6 without concern for the existing space on either side of these two elements. The second end 522 advantageously also extends substantially axially, that is to say substantially parallel to the first end 521. The second end is substantially perpendicular to the distribution axis of the nozzle. According to another advantageous characteristic, the nozzle
(orifice de distribution) se situe à une hauteur axiale sensiblement identique à la hauteur axiale à laquelle s'étend la tige d'actionnement au repos ou à une hauteur axiale supérieure. Une telle configuration est donc tout à fait compatible avec des têtes de distribution compacte ou de forme allongée.(dispensing orifice) is located at an axial height substantially identical to the axial height at which the operating rod extends at rest or at a height axial superior. Such a configuration is therefore quite compatible with compact or elongated distribution heads.
Selon un mode de réalisation particulièrement préféré, le manchon de raccordement 53, le tube 52 et le porte-gicleur 51 sont réalisés monobloc. Une telle réalisation présente bien entendu un avantage indéniable d'un point de vue de la fabrication et de l'assemblage de ces moyens de raccordement flexible. Ceci est possible du fait que l'extrémité 521 s'étend axialement. Une broche de moulage peut ainsi former le conduit interne du tube à partir du manchon. Le tube est moulé droit avec le manchon et le porte-gicleur et ensuite coudé. Le poussoir 7 est destiné à être actionné manuellement par un utilisateur. Ce poussoir comporte une paroi supérieure d'actionnement 70 et deux parois de guidage latérales 71. Un bloc de transmission de poussée axiale 72 s'étend vers le bas à partir de la paroi 70. Ce bloc de transmission comporte deux piliers espacés l'un par rapport à l'autre par un interstice 720. Ces piliers comportent tous deux un évidement pourvu d'une âme de fond 720 dont la fonction sera ci-après décrite.According to a particularly preferred embodiment, the connecting sleeve 53, the tube 52 and the nozzle holder 51 are made in one piece. Such an embodiment of course has an undeniable advantage from a point of view of the manufacture and assembly of these flexible connection means. This is possible because the end 521 extends axially. A molding pin can thus form the inner pipe of the tube from the sleeve. The tube is molded straight with the sleeve and the nozzle holder and then bent. The pusher 7 is intended to be operated manually by a user. This pusher comprises an upper actuating wall 70 and two lateral guide walls 71. An axial thrust transmission block 72 extends downwardly from the wall 70. This transmission block comprises two spaced apart pillars. relative to each other by a gap 720. These pillars both have a recess provided with a bottom core 720 whose function will be described below.
Le poussoir 7 est destiné à être encastré dans la frette d'habillage 3 et ainsi à venir se positionner au dessus de l'insert 4 et de l'embout 5. Ce poussoir 7 commande le déplacement de la tige d'actionnement 11 de sa position de repos représentée sur la figure 2 vers sa position d'actionnement représentée sur la figure 3. Pour ce faire, le poussoir 7 guidé axialement par les parois latérales 31, 33 de la frette 3 est actionné par un appui manuel exercé par l'utilisateur. Les âmes de fond 720 des piliers viennent alors en butée contre les plateformes d'appui 541. Ces butées entraînent alors une descente simultanée de la pièce de guidage et de transmission de poussée 54. Cette descente est alors guidée par les ailettes de guidage 540 coulissant dans les fentes de guidage 410 de l'insert 4. La descente de cette pièce 54 actionne alors la tige 11 qui se déplace dans le corps de pompe et entraîne une diminution de volume de la chambre de pompe. Le produit fluide contenu dans la chambre gagne alors le conduit de distribution défini intérieurement par la tige d'actionnement 11, puis le tube de raccordement flexible 52 avant d'être éjecté au niveau de l'orifice de distribution du gicleur 6. Par ailleurs, il est à noter qu'une partie du tube de raccordement flexible 53 peut s'immiscer dans l'interstice 721. Ceci a pour effet de permettre un maintien de l'orientation du tube 52 et ainsi d'éviter que ce tube gène la coopération entre les âmes de fond 720 et les plateformes d'appui 541.The pusher 7 is intended to be embedded in the trim band 3 and thus to be positioned above the insert 4 and the end piece 5. This pusher 7 controls the displacement of the actuating rod 11 of its rest position shown in Figure 2 to its actuating position shown in Figure 3. To do this, the pusher 7 guided axially by the side walls 31, 33 of the hoop 3 is actuated by a manual support exerted by the user. The bottom cores 720 of the pillars then abut against the bearing platforms 541. These stops then cause a simultaneous lowering of the guide and thrust transmission piece 54. This descent is then guided by the sliding guide vanes 540. in the guide slots 410 of the insert 4. The descent of this part 54 then actuates the rod 11 which moves in the pump body and causes a decrease in volume of the pump chamber. The fluid product contained in the chamber then gains the distribution pipe defined internally by the actuating rod 11, then the flexible connecting tube 52 before being ejected at the dispensing orifice of the nozzle 6. Moreover, it should be noted that a portion of the flexible connecting tube 53 may be interfered with in the gap 721. This has the effect of allowing the orientation of the tube 52 to be maintained and thus to prevent this tube gene co-operation between the bottom webs 720 and the support platforms 541.
Bien que la présente invention ait été décrite en référence à un mode de réalisation particulier de celle-ci, il est entendu qu'elle n'est pas limitée par ce mode de réalisation. Au contraire, un homme du métier peut y apporter toute modification utile sans sortir du cadre de la présente invention tel que défini dans les revendications annexées. Although the present invention has been described with reference to a particular embodiment thereof, it is understood that it is not limited by this embodiment. On the contrary, a person skilled in the art can make any useful modification without departing from the scope of the present invention as defined in the appended claims.
