La présente invention concerne un dispositif de distribution de produit fluide, et plus particulièrement un dispositif de pulvérisation. The present invention relates to a fluid dispensing device, and more particularly to a spraying device.
Les dispositifs de produit fluide sont bien connus dans l'état de la technique, et comportent généralement un réservoir sur lequel est monté un organe de distribution telle qu'une pompe ou une valve doseuse, qui est actionnée au moyen d'une tête de distribution ou d'un poussoir pour expulser une dose de produit à travers un orifice de distribution. Lorsque l'organe de distribution est une pompe, celui-ci comporte généralement un corps de pompe dans lequel un piston coulisse de manière étanche, ledit piston étant actionné par une tige d'actionnement qui est déplacé manuellement par l'utilisateur. La pompe est reliée à un canal d'expulsion qui aboutit à l'orifice de distribution pour distribuer le produit vers l'utilisateur. Fluid product devices are well known in the art, and generally include a reservoir on which is mounted a dispensing member such as a pump or a metering valve, which is actuated by means of a dispensing head or a pusher to expel a dose of product through a dispensing orifice. When the dispensing member is a pump, it generally comprises a pump body in which a piston slides in leaktight manner, said piston being actuated by an actuating rod which is moved manually by the user. The pump is connected to an expulsion channel which ends at the dispensing orifice to dispense the product to the user.
La présente invention a pour but de fournir un dispositif de distribution de produit fluide qui comporte moins de pièces constitutives. The object of the present invention is to provide a device for dispensing a fluid product which comprises fewer constituent parts.
La présente invention a encore pour but de fournir un dispositif de distribution de produit fluide qui soit simple et peu coûteux à fabriquer et à assembler. The present invention also aims to provide a fluid dispensing device which is simple and inexpensive to manufacture and assemble.
La présente invention a également pour but de fournir un dispositif de distribution de produit fluide qui élimine totalement tous risques de contamination du produit contenu à l'intérieur du dispositif, en toute circonstance. The present invention also aims to provide a fluid dispenser device which totally eliminates all risks of contamination of the product contained inside the device, in all circumstances.
La présente invention a donc pour objet un dispositif de distribution de produit fluide, comportant une pompe comportant un corps de pompe et un piston monté coulissant de manière étanche dans ledit corps de pompe, ledit piston étant déplacé par une tige d'actionnement, ledit dispositif comportant un élément tubulaire creux relié à ladite pompe et définissant un canal d'expulsion qui se termine par un orifice de distribution, un insert rigide étant disposé dans ledit canal d'expulsion pour limiter le volume mort, caractérisé en ce que ledit élément tubulaire creux comportant l'orifice de distribution, ladite tige d'actionnement et ledit piston sont réalisés en une seule pièce monobloc. The present invention therefore relates to a fluid dispenser device, comprising a pump comprising a pump body and a piston mounted to slide in leaktight manner in said pump body, said piston being moved by an actuating rod, said device comprising a hollow tubular element connected to said pump and defining an expulsion channel which ends in a dispensing orifice, a rigid insert being disposed in said expulsion channel to limit the dead volume, characterized in that said hollow tubular element comprising the dispensing orifice, said actuating rod and said piston are produced in a single piece.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
Avantageusement, un insert rigide est disposé dans ledit canal d'expulsion pour limiter le volume mort. Advantageously, a rigid insert is placed in said expulsion channel to limit the dead volume.
Avantageusement, un obturateur est disposé dans ledit canal d'expulsion, en aval dudit orifice de distribution
Avantageusement, la pompe comporte un second piston coulissant dans ledit corps de pompe, ledit second piston formant aussi partie de ladite pièce monobloc. Advantageously, a shutter is disposed in said expulsion channel, downstream of said dispensing orifice
Advantageously, the pump comprises a second piston sliding in said pump body, said second piston also forming part of said piece.
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante d'un mode de réalisation particulier de celle-ci, en référence à la figure unique jointe, donnée à titre d'exemple non limitatif, et qui représente une vue schématique en section transversale un dispositif de distribution de produit fluide selon un mode de réalisation avantageux de la présente invention. Other characteristics and advantages of the present invention will appear more clearly during the following detailed description of a particular embodiment thereof, with reference to the attached single figure, given by way of nonlimiting example, and which represents a schematic cross-sectional view of a fluid dispenser device according to an advantageous embodiment of the present invention.
La présente invention s'applique à tous types de dispositif de distribution de produit fluide, et l'exemple représenté sur la figure unique n'est qu'un mode de réalisation avantageux, la présente invention n'étant nullement limitée à ce mode de réalisation. The present invention applies to all types of fluid dispensing device, and the example shown in the single figure is only an advantageous embodiment, the present invention being in no way limited to this embodiment. .
Le dispositif de distribution de produit fluide comporte un réservoir (non représenté), sur lequel est fixée une pompe 10 au moyen d'une bague de fixation 20. En l'occurrence, sur la figure, il s'agit d'une bague encliquetable. Bien entendu, tous types de moyen de fixation sont envisageables. La pompe 10 comporte un corps de pompe 11 relié à l'intérieur du réservoir, et dans lequel coulisse un piston 12, de manière étanche, pour distribuer sélectivement le produit contenu dans le réservoir. The fluid dispenser device comprises a reservoir (not shown), on which a pump 10 is fixed by means of a fixing ring 20. In this case, in the figure, it is a snap ring . Of course, all types of fixing means can be envisaged. The pump 10 comprises a pump body 11 connected to the interior of the reservoir, and in which a piston 12 slides, in leaktight manner, for selectively distributing the product contained in the reservoir.
Le piston 12 est actionné par une tige d'actionnement 13 qui est déplacé manuellement par l'utilisateur au moyen d'un poussoir 30 comportant des surfaces d'appui correspondantes pour l'actionnement du dispositif. Bien entendu, la forme du poussoir 30 peut être quelconque. Le dispositif comporte en outre un élément tubulaire creux 15 qui définit à l'intérieur un canal d'expulsion 16 relié d'une part à la pompe 10 et d'autre part à un orifice de distribution 17 qui termine ledit canal d'expulsion 16. Ledit orifice de distribution 17 est donc défini par l'extrémité dudit élément tubulaire creux The piston 12 is actuated by an actuating rod 13 which is moved manually by the user by means of a pusher 30 having corresponding bearing surfaces for actuating the device. Of course, the shape of the pusher 30 can be arbitrary. The device further comprises a hollow tubular element 15 which defines inside an expulsion channel 16 connected on the one hand to the pump 10 and on the other hand to a dispensing orifice 17 which terminates said expulsion channel 16 Said dispensing orifice 17 is therefore defined by the end of said hollow tubular element

15, comme visible sur la figure. De préférence, un insert rigide 18 est disposé dans ledit canal d'expulsion 16 pour limiter le volume mort, ce qui favorise la pulvérisation du produit. Avantageusement, on peut disposer un profil de pulvérisation au niveau de l'orifice de distribution 17 et/ou un obturateur 50, comme représenté sur la figure. 15, as shown in the figure. Preferably, a rigid insert 18 is placed in said expulsion channel 16 to limit the dead volume, which promotes spraying of the product. Advantageously, there may be a spray profile at the distribution orifice 17 and / or a shutter 50, as shown in the figure.
Selon l'invention, l'élément tubulaire creux 15, la tige d'actionnement
13 et ledit piston 12 sont réalisés en une seule pièce monobloc 100. Ainsi, tout risque de contamination du produit contenu dans la pompe est empêché du fait qu'il est impossible de désolidariser l'orifice de distribution 17 de la pompe 10, comme cela est le cas avec les dispositifs de distribution de produit fluide connus. En effet, généralement, l'orifice de distribution fait partie de la tête de distribution, et un enlèvement de ladite tête de distribution implique un risque de contamination au niveau de la jonction entre la pompe et la tête. Ici, la pièce monobloc 100, avec éventuellement la présence de l'obturateur 50 au niveau de l'orifice de distribution 17, garantie une élimination totale du risque de contamination. De plus, la présente invention permet de réaliser un dispositif de distribution de produit fluide avec moins de pièces constitutives, la pièce 100 pouvant être moulée aisément, de sorte que le coût de fabrication est diminué. According to the invention, the hollow tubular element 15, the actuating rod
13 and said piston 12 are made in a single piece 100. Thus, any risk of contamination of the product contained in the pump is prevented because it is impossible to separate the dispensing orifice 17 from the pump 10, like this is the case with known fluid dispenser devices. Indeed, generally, the dispensing orifice is part of the dispensing head, and a removal of said dispensing head implies a risk of contamination at the junction between the pump and the head. Here, the single piece 100, possibly with the presence of the shutter 50 at the distribution orifice 17, guarantees total elimination of the risk of contamination. In addition, the present invention makes it possible to produce a fluid dispenser device with fewer constituent parts, the part 100 being able to be molded easily, so that the manufacturing cost is reduced.
En référence à la figure unique, la pompe 10 représentée peut comporter un second piston 19 qui est également coulissant de manière étanche dans ledit corps de pompe 11, ledit second piston formant également partie de ladite pièce monobloc 100. With reference to the single figure, the pump 10 shown may include a second piston 19 which is also sliding in leaktight manner in said pump body 11, said second piston also forming part of said monobloc part 100.
La présente invention a été représentée en référence à un exemple de réalisation, mais il est entendu que l'homme du métier peut y apporter toutes les modifications souhaitées sans sortir du cadre de la présente invention qui est définie par les revendications annexées. The present invention has been shown with reference to an exemplary embodiment, but it is understood that a person skilled in the art can make any desired modifications thereto without departing from the scope of the present invention which is defined by the appended claims.
