Description

Procédé de fabrication d'un obturateur, poussoir et tête de distribution incorporant un tel obturateur. Method of manufacturing a shutter, pusher and dispensing head incorporating such a shutter.
La présente invention concerne un obturateur ainsi qu'un poussoir dans lequel ledit obturateur est monté.The present invention relates to a shutter and a pusher in which said shutter is mounted.
De manière générale, un obturateur a pour fonction de définir un passage de sortie fermé à son extrémité par des moyens d'obturation. Au repos, les moyens d'obturation maintiennent le passage de sortie hermétiquement fermé et dès qu'une pression suffisante est exercée sur le produit fluide se trouvant dans le passage de sortie, les moyens d'obturation s'ouvrent de manière à définir un orifice de distribution à l'extrémité du passage de sortie. Il s'agit là d'un obturateur d'une conception tout à fait classique. L'obturation est réalisé par un contact étanche entre deux pièces. Il a cependant été constaté que ce contact ne présente pas une qualité suffisante pour permettre aux distributeurs sur lesquels l'obturateur est monté d'être parfaitement étanches. Il s'ensuit par conséquent des fuites sous la forme de suintement qui rendent le distributeur peu attrayant. La qualité du contact est donc essentielle pour créer une étanchéité de qualité.In general, a shutter has the function of defining an outlet passage closed at its end by shutter means. At rest, the closure means keep the outlet passage hermetically closed and as soon as sufficient pressure is exerted on the fluid in the outlet passage, the closure means open so as to define an orifice distribution at the end of the outlet passage. This is a shutter with a completely classic design. The obturation is achieved by a tight contact between two parts. However, it has been found that this contact is not of sufficient quality to allow the distributors on which the shutter is mounted to be perfectly sealed. This therefore results in leaks in the form of oozing which make the dispenser unattractive. The quality of the contact is therefore essential to create a quality seal.
Selon un procédé de fabrication conventionnel, les deux pièces sont moulées séparément puis on les assemble. Du fait que ces deux pièces sont moulées séparément, on ne peut garantir que les surfaces de contact sont parfaitement correspondantes et jointives, d'où il en résulte le risque de fuite. En outre, même avec des pièces réalisées avec une très grande précision, elles sont déformées lors de l'assemblage, ce qui nuit à la qualité du contact étanche. Pour ces multiples raisons, l'étanchéité des obturateurs conventionnels n'est pas remarquable.According to a conventional manufacturing process, the two parts are molded separately and then assembled. Since these two parts are molded separately, it cannot be guaranteed that the contact surfaces are perfectly corresponding and contiguous, which results in the risk of leakage. In addition, even with parts produced with very high precision, they are deformed during assembly, which affects the quality of the sealed contact. For these multiple reasons, the sealing of conventional shutters is not remarkable.
Une technique efficace consiste à mouler les deux pièces dans le même moule. Cette technique de moulage est souvent désignée sous le terme de bi-injection. Une telle technique est mise en œuvre sur leur obturateur dans les documents EP-0 713 832 et EP-0 673 852. Dans le premier de ces documents, l'obturateur comprend un embout rigide co-moulé avec une pièce élastique. L'ensemble est ensuite mis en place sur une sortie tubulaire. La pièce élastique est moulée sur l'embout de manière à créer une fixation mécanique étant donné que les matériaux constitutifs des deux pièces sont chimiquement incompatibles. En variante, c'est la sortie tubulaire qui coince la pièce élastique dans l'embout. Dans le second document, la pièce élastique forme un talon d'ancrage pour sa fixation sur une tête de distribution.An effective technique is to mold the two parts in the same mold. This molding technique is often referred to as bi-injection. Such a technique is implemented on their shutter in documents EP-0 713 832 and EP-0 673 852. In the first of these documents, the shutter comprises a rigid end piece co-molded with an elastic piece. The assembly is then placed on a tubular outlet. The elastic part is molded on the end piece so as to create a mechanical fixing since the materials constituting the two parts are chemically incompatible. Alternatively, it is the tubular outlet which clamps the part elastic in the mouthpiece. In the second document, the elastic piece forms an anchor heel for fixing to a dispensing head.
On peut donc remarquer qu'il y a un réel problème à fixer la pièce élastique sur la pièce rigide du fait de leur incompatibilité chimique. La présente invention a pour but de résoudre ce problème de fixation.It can therefore be noted that there is a real problem in fixing the elastic part on the rigid part because of their chemical incompatibility. The object of the present invention is to solve this fixing problem.
Pour atteindre ce but, la présente invention propose un obturateur destiné à être monté sur un organe de distribution de produit fluide pour en obturer la sortie de distribution, ledit obturateur comprenant deux pièces, les deux pièces formant respectivement un noyau sensiblement dur et une enveloppe sensiblement élastique entourant partiellement le noyau, les moyens d'obturation étant définis par une partie élastiquement déformable de l'enveloppe en contact étanche avec le noyau.To achieve this object, the present invention provides a shutter intended to be mounted on a fluid dispenser member for closing the dispensing outlet, said shutter comprising two parts, the two parts respectively forming a substantially hard core and a substantially envelope elastic partially surrounding the core, the closure means being defined by an elastically deformable part of the envelope in sealed contact with the core.
Avantageusement, les deux pièces sont réalisées dans un même moule par un procédé de moulage successif à double injection, les matériaux constituant respectivement les deux pièces étant chimiquement incompatibles de sorte que les deux pièces n'adhèrent pas l'une à l'autre après moulage. La technique de bi-injection présente dans notre cas un avantage particulier : en effet, étant donné que les deux pièces sont moulées successivement dans un même moule, la surface d'une des deux pièces sert de surface de moule pour l'autre pièce, de sorte que les surfaces respectives des deux pièces en contact l'une de l'autre sont parfaitement jointives. En d'autres termes, la surface d'une des pièces est parfaitement conforme au profil de surface de l'autre pièce, puisqu'elle a été moulé dessus. En outre, avec cette technique de moulage, les deux pièces sont moulées à l'état final, ce qui évite une opération ultérieure de montage par emmanchage qui risque d'altérer une des pièces.Advantageously, the two parts are produced in the same mold by a successive double injection molding process, the materials constituting the two parts respectively being chemically incompatible so that the two parts do not adhere to each other after molding. . The bi-injection technique has a particular advantage in our case: in fact, since the two parts are molded successively in the same mold, the surface of one of the two parts serves as the mold surface for the other part, so that the respective surfaces of the two parts in contact with each other are perfectly contiguous. In other words, the surface of one of the parts conforms perfectly to the surface profile of the other part, since it has been molded thereon. In addition, with this molding technique, the two parts are molded in the final state, which avoids a subsequent assembly operation by fitting which risks altering one of the parts.
En commençant par exemple par mouler le noyau, sa surface extérieure servira de surface de moulage pour l'enveloppe qui va ensuite être moulée dessus dans le même moule. A l'inverse, si l'on commence par mouler l'enveloppe, sa surface interne servira de surface de moulage pour le noyau. On garantit ainsi une parfaite concordance des surfaces de l'enveloppe et de noyau définissant le contact étanche.Beginning for example by molding the core, its outer surface will serve as a molding surface for the envelope which will then be molded on it in the same mold. Conversely, if we start by molding the envelope, its internal surface will serve as a molding surface for the core. This guarantees perfect concordance of the envelope and core surfaces defining the tight contact.
En enveloppant au moins partiellement le noyau, l'enveloppe possède une surface de contact étendue avec le noyau, ce qui lui garantit une bonne fixation.By at least partially enveloping the core, the envelope has an extended contact surface with the core, which guarantees good fixation.
L'invention définit également un poussoir de pompe ou de valve formant un logement recevant un obturateur comprenant deux pièces définissant ensemble un passage de sortie (18) et des moyens d'obturation aptes à fermer le passage de sortie au repos et à ouvrir le passage de sortie pour définir un orifice de distribution lorsqu'une pression prédéterminée est appliquée au produit fluide dans le passage de sortie, caractérisé en ce que les deux pièces forment respectivement un noyau sensiblement dur et une enveloppe sensiblement élastique entourant partiellement le noyau, les moyens d'obturation étant définis par une partie élastiquement déformable de l'enveloppe en contact étanche avec le noyau. Avantageusement, les deux pièces sont réalisées dans un même moule par un procédé de moulage successif à double injection, les matériaux constituant respectivement les deux pièces étant chimiquement incompatibles de sorte que les deux pièces n'adhèrent pas l'une à l'autre après moulage.The invention also defines a pump or valve pusher forming a housing receiving a shutter comprising two parts together defining an outlet passage (18) and shutter means able to close the outlet passage at rest and to open the passage outlet to define a dispensing orifice when a predetermined pressure is applied to the fluid in the outlet passage, characterized in that the two parts respectively form a substantially hard core and a substantially elastic envelope partially surrounding the core, the closure means being defined by an elastically deformable part of the envelope in sealed contact with the core. Advantageously, the two parts are produced in the same mold by a successive double injection molding process, the materials constituting the two parts respectively being chemically incompatible so that the two parts do not adhere to each other after molding .
Selon une autre caractéristique, l'enveloppe comprend des moyens d'ancrage sur le noyau. Ainsi, à la sortie du moule, l'obturateur se présente sous la forme d'un élément unitaire réalisé par un moulage bi-injection/bi-matière.According to another characteristic, the envelope comprises means for anchoring to the core. Thus, at the outlet of the mold, the shutter is in the form of a unitary element produced by a bi-injection / bi-material molding.
Selon une autre caractéristique de l'invention, le noyau comprend des moyens d'accrochage dans le logement.According to another characteristic of the invention, the core comprises means for hooking in the housing.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif deux modes de réalisation de l'invention.The invention will now be described more fully with reference to the accompanying drawings which give two embodiments of the invention by way of non-limiting example.
Sur les dessins : la figure 1 est une vue en coupe transversale à travers un poussoir de pompe ou de valve équipé d'un obturateur de l'invention, et les figures 2a et 2b sont des vues en section transversale, resp. horizontale et verticale, à travers un obturateur selon une deuxième forme de réalisation de la présente invention.In the drawings: FIG. 1 is a cross-sectional view through a pump or valve pusher fitted with a shutter of the invention, and FIGS. 2a and 2b are views in cross section, resp. horizontal and vertical, through a shutter according to a second embodiment of the present invention.
En se référant indifféremment aux figures, on voit que l'obturateur désigné dans son ensemble par la référence numérique 1, comprend un noyau interne 15 et une enveloppe externe 11 définissant ensemble un passage de sortie 18 obturé par des moyens d'obturation constitués par un contact étanche d'une partie élastique déformable 12 en contact avec une partie d'extrémité du noyau 15 formant un pointeau 16. A l'état de repos, c'est-à-dire lorsqu'aucune pression n'est exercée sur le produit fluide se trouvant dans le passage 18, la partie élastiquement déformable 12 reste en contact étanche avec le pointeau 16 du noyau 15. En revanche, dès que la pression dans le passage 18 dépasse une valeur prédéterminée, la partie 12 de l'enveloppe 11 se déforme élastiquement vers l'extérieur en définissant un orifice de distribution qui fait communiquer le passage de sortie 18 avec l'extérieur. Dès que la pression descend en dessous de ladite valeur prédéterminée, la partie 12 de l'enveloppe 11 reprend son contact étanche sur le pointeau 16 du noyau 15 et l'obturateur est de nouveau dans son état de repos.Referring indifferently to the figures, it can be seen that the shutter designated as a whole by the reference numeral 1, comprises an internal core 15 and an external casing 11 together defining an outlet passage 18 closed by shutter means constituted by a sealed contact of a deformable elastic part 12 in contact with an end part of the core 15 forming a needle 16. In the rest state, that is to say when no pressure is exerted on the product fluid being in the passage 18, the elastically deformable part 12 remains in sealed contact with the needle 16 of the core 15. On the other hand, as soon as the pressure in the passage 18 exceeds a predetermined value, the part 12 of the envelope 11 elastically deforms outwards by defining a dispensing orifice which communicates the outlet passage 18 with the outside. As soon as the pressure drops below said predetermined value, the part 12 of the envelope 11 resumes its tight contact on the needle 16 of the core 15 and the shutter is again in its rest state.
Dans les deux formes de réalisation, l'enveloppe élastique 11 entoure au moins partiellement le noyau 15, de sorte qu'ils partagent une surface de contact très étendue. Ceci garantie une parfaite fixation de l'enveloppe sur le noyau, sans qu'il soit nécessaire de prévoir des moyens de fixation additionnels comme c'est le cas avec le talon du document EP-0 673 852 et de la sortie tubulaire du document EP-0 713 832.In both embodiments, the elastic envelope 11 at least partially surrounds the core 15, so that they share a very large contact surface. This guarantees perfect attachment of the envelope to the core, without the need for additional attachment means as is the case with the heel of document EP-0 673 852 and the tubular outlet of document EP -0 713 832.
Bien entendu, l'enveloppe externe 11 peut en outre comprendre des moyens d'ancrage 13 sur le noyau, par exemple sous la forme d'une surépaisseur qui s'étend au moins partiellement sur la périphérie de l'enveloppe. Cette surépaisseur ou talon d'ancrage 13 permet encore d'améliorer la fixation de l'enveloppe 11 sur le noyau 15. On peut bien entendu imaginer d'autres formes de réalisation pour les moyens d'ancrage 13, qui ne sont pas obligatoires pour l'invention.Of course, the outer casing 11 may further comprise anchoring means 13 on the core, for example in the form of an additional thickness which extends at least partially over the periphery of the casing. This additional thickness or anchor heel 13 further improves the fixing of the casing 11 on the core 15. It is of course possible to imagine other embodiments for the anchoring means 13, which are not compulsory for the invention.
En se référant maintenant plus particulièrement à la figure 1, on voit que l'obturateur 1 est intégré dans un poussoir 2 destiné à être monté sur la tige d'actionnement d'une pompe ou d'une valve (non représentée). Pour cela, le poussoir 2 définit un logement d'emmanchage 26 destiné à recevoir l'extrémité supérieure libre de la tige d'actionnement de la pompe ou de la valve. Ce logement d'emmanchage 26 fait communiquer la tige d'actionnement creuse de la pompe ou de la valve avec le passage de sortie 18 par l'intermédiaire de conduits de liaison 24 et 25. En outre, le poussoir 2 définit une surface supérieure de poussée et une jupe périphérique cylindrique 23. Pour la réception de l'obturateur 1, le poussoir 2 définit un logement 20 qui débouche latéralement dans la jupe cylindrique 23. Ce logement 20 avant le montage de l'obturateur 1 communique directement avec la tige d'actionnement creuse par l'intermédiaire des conduits 24 et 25. Après montage, le logement 20 est entièrement rempli par l'obturateur 1 à l'exception du passage de sortie 18 qui communique avec les conduits 24 et 25 jusqu'à la tige d'actionnement creuse. Pour la fixation de l'obturateur 1 dans le logement 20 du poussoir 2, le noyau 15 est pourvu de moyens d'accrochage sous la forme d'un bourrelet extérieur 17 qui vient s'encliqueter dans un logement correspondant formé dans le logement 20. On peut bien entendu imaginer d'autres formes de réalisation pour les moyens d'accrochage 17 de l'obturateur 1 dans le logement 20 du poussoir 2. Referring now more particularly to Figure 1, we see that the shutter 1 is integrated in a pusher 2 intended to be mounted on the actuating rod of a pump or a valve (not shown). For this, the pusher 2 defines a fitting housing 26 intended to receive the free upper end of the actuating rod of the pump or of the valve. This fitting housing 26 communicates the hollow actuating rod of the pump or of the valve with the outlet passage 18 by means of connecting conduits 24 and 25. In addition, the pusher 2 defines an upper surface of thrust and a cylindrical peripheral skirt 23. For the reception of the shutter 1, the pusher 2 defines a housing 20 which opens laterally into the cylindrical skirt 23. This housing 20 before mounting the shutter 1 communicates directly with the rod d hollow actuation via the conduits 24 and 25. After assembly, the housing 20 is completely filled by the shutter 1 with the exception of the outlet passage 18 which communicates with the conduits 24 and 25 up to the rod d 'hollow actuation. For fixing the shutter 1 in the housing 20 of the pusher 2, the core 15 is provided with hooking means in the form of an external bead 17 which snaps into a corresponding housing formed in the housing 20. One can of course imagine other embodiments for the attachment means 17 of the shutter 1 in the housing 20 of the pusher 2.
