Description

Pompe de distribution de produit fluide à actionnement manuel Fluid dispensing pump with manual actuation
La présente invention concerne une pompe de distribution de produit fluide à actionnement manuel.The present invention relates to a fluid dispensing pump with manual actuation.
Dans ce type de pompe, il est généralement prévu une pompe montée sur un réservoir contenant le produit fluide, et actionnée au moyen d'une tête de distribution ou poussoir, assemblée sur ladite pompe. La pompe comporte généralement un corps de pompe dans laquelle coulisse un piston entre une position de repos et une position d'actionnement. Ce piston est généralement relié à une tige d'actionnement adaptée à transmettre la force d'actionnement manuel exercée par l'utilisateur sur la tête ou poussoir. Un élément de butée, tel qu'une virole, est généralement assemblé dans le bord supérieur du corps de pompe, pour définir h position de repos dudit piston. Cette virole s'étend généralement à l'intérieur du corps de pompe, de sorte que la tige d'actionnement coulisse à l'intérieur de cette virole. L'étanchéité entre la tige d'actionnement et la pompe est généralement réalisée au niveau du piston qui coulisse de manière étanche à l'intérieur dudit corps de pompe. L'étanchéité entre le corps de pompe, la virole et la bague de fixation est généralement réalisée au moyen d'un joint qui est interposé entre ledit corps de pompe et ladite bague de fixation. La liaison entre la tige d'actionnement et la virole n'est pas nécessairement étanche puisque cette étanchéité est assurée par les points d'étanchéité décrits ci-dessus. Les pompes du type décrit ci-dessus fonctionnent de manière satisfaisante, mais peuvent toutefois présenter certains inconvénients. Ainsi, lorsque l'utilisateur exerce une force d'actionnement qui n'est pas exactement axiale, la tige d'actionnement peut être décentrée pendant son actionnement, ce qui peut entraîner un dysfonctionnement de la pompe ou un actionnement difficile de celle-ci. De même, la tige d'actionnement ne coopérant pas nécessairement de manière étanche avec la virole, il peut y avoir un certain jeu entre ces deux éléments de sorte que la tige d'actionnement n'est pas nécessairement centrée par rapport à la virole et donc par rapport au corps de pompe, ce qui peut entraîner un dysfonctionnement de la pompe lors de son actionnement.In this type of pump, there is generally provided a pump mounted on a reservoir containing the fluid, and actuated by means of a dispensing head or pusher, assembled on said pump. The pump generally comprises a pump body in which a piston slides between a rest position and an actuation position. This piston is generally connected to an actuating rod adapted to transmit the manual actuating force exerted by the user on the head or pusher. A stop element, such as a ferrule, is generally assembled in the upper edge of the pump body, to define h rest position of said piston. This ferrule generally extends inside the pump body, so that the actuating rod slides inside this ferrule. The seal between the actuating rod and the pump is generally carried out at the level of the piston which slides in leaktight manner inside said pump body. The seal between the pump body, the ferrule and the fixing ring is generally achieved by means of a seal which is interposed between said pump body and said fixing ring. The connection between the actuating rod and the ferrule is not necessarily sealed since this sealing is ensured by the sealing points described above. Pumps of the type described above operate satisfactorily, but may however have certain drawbacks. Thus, when the user exerts an actuating force which is not exactly axial, the actuating rod can be offset during its actuation, which can cause a malfunction of the pump or a difficult actuation thereof. Likewise, the actuating rod not necessarily cooperating in a leaktight manner with the ferrule, there may be a certain clearance between these two elements so that the actuating rod is not necessarily centered relative to the ferrule and so compared to the body of pump, which can cause the pump to malfunction when activated.
La présente invention a pour but de fournir une pompe de distribution de produit fluide qui ne reproduit pas les inconvénients susmentionnés. En particulier, la présente invention a pour but de fournir une pompe de distribution de produit fluide à actionnement manuel qui garantisse un fonctionnement sûr et fiable de la pompe, même lorsque la force d'actionnement exercée par l'utilisateur n'est pas exactement axiale.The object of the present invention is to provide a fluid dispensing pump which does not have the abovementioned drawbacks. In particular, the object of the present invention is to provide a pump for dispensing a fluid with manual actuation which guarantees safe and reliable operation of the pump, even when the actuating force exerted by the user is not exactly axial. .
La présente invention a également pour but de fournir une telle pompe qui améliore l'étanchéité.The present invention also aims to provide such a pump which improves sealing.
La présente invention a aussi pour but de fournir une telle pompe qui soit simple et peu coûteuse à fabriquer et à assembler.The present invention also aims to provide such a pump which is simple and inexpensive to manufacture and assemble.
La présente invention a donc pour objet une pompe de distribution de produit fluide à actionnement manuel comprenant un corps de pompe, un piston coulissant de manière étanche dans ledit corps de pompe, entre une position de repos et une position d'actionnement, une tige d'actionnement reliée, de préférence de manière monobloc, audit piston, et une virole, fixée au bord supérieur du corps de pompe, pour définir la position de repos dudit piston, ladite tige d'actionnement coulissant dans ladite virole, caractérisée en ce que ladite virole comporte au moins une lèvre d'étanchéité interne coopérant de manière étanche avec ladite tige d'actionnement.The present invention therefore relates to a fluid dispensing pump with manual actuation comprising a pump body, a piston sliding in leaktight manner in said pump body, between a rest position and an actuation position, a rod of actuation connected, preferably in a single piece, to said piston, and a ferrule, fixed to the upper edge of the pump body, to define the rest position of said piston, said actuating rod sliding in said ferrule, characterized in that said ferrule comprises at least one internal sealing lip cooperating in leaktight manner with said actuating rod.
Avantageusement, ladite au moins une lèvre d'étanchéité s'étend sur toute la périphérie interne de ladite virole.Advantageously, said at least one sealing lip extends over the entire internal periphery of said ferrule.
Avantageusement, ladite au moins une lèvre d'étanchéité est réalisée d'une pièce monobloc avec ladite virole.Advantageously, said at least one sealing lip is made in one piece with said ferrule.
Avantageusement, ladite au moins une lèvre d'étanchéité est souple, de manière à assurer l'étanchéité avec ladite tige d'actionnement, même lorsque la force d'actionnement exercée sur la tige d'actionnement n'est pas exactement axiale. Avantageusement, ladite lèvre d'étanchéité de la virole réalise un centrage et/ ou un guidage de la tige d'actionnement dans ladite virole et/ ou ledit corps de pompe.Advantageously, said at least one sealing lip is flexible, so as to ensure sealing with said actuating rod, even when the actuating force exerted on the actuating rod is not exactly axial. Advantageously, said sealing lip of the ferrule provides centering and / or guiding of the actuating rod in said ferrule and / or said pump body.
Avantageusement, ladite virole est réalisée d'une pièce monobloc avec une bague de fixation prévue pour fixer ladite pompe sur un réservoir de produit fluide.Advantageously, said ferrule is made of a single piece with a fixing ring provided for fixing said pump on a reservoir of fluid product.
Selon une première variante, ladite virole est réalisée en une seule matière.According to a first variant, said ferrule is made of a single material.
Selon une seconde variante, ladite virole est réalisée en plusieurs matières. La présente invention a également pour objet un dispositif de distribution de produit fluide comportant une pompe telle que décrite ci-dessus.According to a second variant, said ferrule is made of several materials. The present invention also relates to a device for dispensing a fluid product comprising a pump as described above.
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante de celle- ci, faite en référence aux dessins joints, donnés à titres d'exemples non limitatifs, et sur lesquels :Other characteristics and advantages of the present invention will appear more clearly during the following detailed description thereof, given with reference to the accompanying drawings, given by way of nonlimiting examples, and in which:
- la figure 1 est une vue schématique en section transversale d'un dispositif de distribution de produit fluide selon un mode de réalisation avantageux de la présente invention, etFIG. 1 is a diagrammatic view in cross section of a device for dispensing a fluid product according to an advantageous embodiment of the present invention, and
- la figure 2 est une vue de détail à échelle agrandie d'une partie du dispositif représenté sur la figure 1.FIG. 2 is a detail view on an enlarged scale of a part of the device shown in FIG. 1.
En référence aux figures, le dispositif de distribution de produit fluide comporte un réservoir 1 contenant le produit fluide à distribuer. Une pompe est montée de manière étanche sur ce réservoir 1 au moyen d'une bague de fixation 50, qui peut être quelconque, et notamment vissable, encliquetable ou sertissable. Une tête de distribution ou poussoir 3 est assemblé(e) sur la pompe pour actionner celle-ci. L'utilisateur qui souhaite utiliser le dispositif, exerce une force axiale sur le poussoir 3, cette force étant transmise par l'intermédiaire d'une tige d'actionnement 30 à un piston 20 qui coulisse de manière étanche à l'intérieur du corps de pompe 10. De préférence, la pompe est une pompe à précompression comportant une chambre de pompe qui contient la dose de produit à expulser à chaque actionnement. De manière connue, un élément de butée, tel qu'une virole 40, est fixé au bord supérieur 11 du corps de pompe 10 pour définir la position de repos du piston 20. Cette virole 40 peut être emmanchée à force dans le corps de pompe 10, ou en variante y être fixée par tout autre moyen approprié.Referring to the figures, the fluid dispenser device comprises a reservoir 1 containing the fluid product to be dispensed. A pump is mounted in leaktight manner on this reservoir 1 by means of a fixing ring 50, which can be any, and in particular screwable, snap-on or crimpable. A dispensing head or pusher 3 is assembled on the pump in order to actuate the latter. The user who wishes to use the device exerts an axial force on the pusher 3, this force being transmitted via an actuating rod 30 to a piston 20 which slides in leaktight manner inside the body of pump 10. Preferably, the pump is a precompression pump comprising a pump chamber which contains the dose of product to be expelled on each actuation. In known manner, a stop element, such as a ferrule 40, is fixed to the upper edge 11 of the pump body 10 to define the rest position of the piston 20. This ferrule 40 can be force-fitted into the pump body 10, or as a variant be fixed there by any other appropriate means .
Par exemple, la virole peut être montée sur le bord supérieur 11 du corps de pompe, puis une bague de fixation 50 est assemblée autour dudit bord supérieur du corps de pompe avec interposition d'un joint d'étanchéité. La bague de fixation 50 est ensuite assemblée sur le réservoir 1, généralement avec interposition d'un joint de col 5. En variante, l'exemple représenté sur les figures montre une virole 40 réalisée d'une pièce monobloc avec ladite bague de fixation 50. Un passage d'air d'éventation 60 peut être prévu dans cette pièce monobloc, et un filtre pour l'air d'éventation pourrait lui être associé (non représenté). De cette manière, on économise des pièces constitutives, et on diminue donc les coûts de fabrication et d'assemblage du dispositif.For example, the ferrule can be mounted on the upper edge 11 of the pump body, then a fixing ring 50 is assembled around said upper edge of the pump body with the interposition of a seal. The fixing ring 50 is then assembled on the reservoir 1, generally with the interposition of a neck gasket 5. As a variant, the example shown in the figures shows a ferrule 40 produced in one piece with said fixing ring 50 A vent air passage 60 can be provided in this monobloc piece, and a filter for the vent air could be associated with it (not shown). In this way, component parts are saved, and the manufacturing and assembly costs of the device are therefore reduced.
La virole 40 comporte avantageusement une partie de guidage 46 adaptée à guider la tige d'actionnement 30 pendant son déplacement.The ferrule 40 advantageously comprises a guide portion 46 adapted to guide the actuating rod 30 during its movement.
Selon l'invention, la virole 40 comporte en outre au moins une lèvre d'étanchéité interne 45, qui s'étend de préférence sur toute la périphérie de la surface interne de ladite virole 40. Cette lèvre d'étanchéité 45 est de préférence souple et coopère de manière étanche avec la tige d'actionnement 30 dans toutes les positions de celle-ci. De préférence, ladite lèvre d'étanchéité 45 est réalisée de manière monobloc avec la virole 40. Cette lèvre d'étanchéité 45 permet de réaliser, de manière économique et simple, simultanément les trois fonctions suivantes :According to the invention, the ferrule 40 further comprises at least one internal sealing lip 45, which preferably extends over the entire periphery of the internal surface of said ferrule 40. This sealing lip 45 is preferably flexible and cooperates sealingly with the actuating rod 30 in all of the positions thereof. Preferably, said sealing lip 45 is produced in a single piece with the ferrule 40. This sealing lip 45 makes it possible, simultaneously and economically, to perform the following three functions:
- la liaison entre la tige d'actionnement 30 et la virole 40 est étanche en toutes positions de la pompe,the connection between the actuating rod 30 and the ferrule 40 is sealed in all positions of the pump,
- la lèvre d'étanchéité 45 est souple et exerce une certaine contrainte radiale sur la tige d'actionnement 30, de sorte que même en cas d'une force d'actionnement qui n'est pas tout à fait axiale, l'étanchéité entre la tige d'actionnement 30 et la virole 40 est maintenue par déformation de ladite lèvre d'étanchéité 45, - la contrainte radiale exercée par la lèvre d'étanchéité 45 sur la tige d'actionnement 30 provoque un centrage de cette tige d'actionnement dans le corps de pompe et dans la virole, en position de repos, mais aussi lors de l' actionnement. La partie de guidage 46 peut aussi contribuer à ce centrage.- The sealing lip 45 is flexible and exerts a certain radial stress on the actuating rod 30, so that even in the event of an actuating force which is not entirely axial, the seal between the actuating rod 30 and the ferrule 40 is held by deformation of said sealing lip 45, - The radial stress exerted by the sealing lip 45 on the actuating rod 30 causes this actuating rod to be centered in the pump body and in the shell, in the rest position, but also during actuation. . The guide portion 46 can also contribute to this centering.
La fiabilité de la pompe est donc améliorée, en ce que les risques de dysfonctionnement ou de blocage de celle-ci lors de l'application d'une force d'actionnement qui ne serait pas exactement axiale, sont éliminés ou pour le moins fortement diminués. Dans le mode de réalisation représenté sur les figures, dans laquelle la virole 40 est réalisée d'une pièce avec la bague de fixation 50, on diminue encore les coûts de fabrication et d'assemblage en diminuant le nombre de pièces constitutives.The reliability of the pump is therefore improved, in that the risks of malfunctioning or of blocking thereof during the application of an actuating force which is not exactly axial, are eliminated or at least greatly reduced . In the embodiment shown in the figures, in which the ferrule 40 is made in one piece with the fixing ring 50, the manufacturing and assembly costs are further reduced by reducing the number of component parts.
La virole 40 peut être réalisée en une seule matière. En variante, elle peut être réalisée en plusieurs matières. En particulier, la lèvre d'étanchéité pourrait être réalisée en un matériau plus souple que le reste de la virole. Ceci permet d'assurer une souplesse optimale de la lèvre pour assurer l'étanchéité, tout en gardant la rigidité nécessaire au bon fonctionnement de la pompe pour le reste de la virole. De même, lorsque la virole 40 est réalisée d'une pièce avec la bague de fixation, différentes matières pourraient être utilisées.The ferrule 40 can be made of a single material. Alternatively, it can be made of several materials. In particular, the sealing lip could be made of a more flexible material than the rest of the shell. This ensures optimum flexibility of the lip to ensure sealing, while retaining the rigidity necessary for the proper functioning of the pump for the rest of the shell. Similarly, when the ferrule 40 is made in one piece with the fixing ring, different materials could be used.
En variante au mode de réalisation représenté, la virole pourrait comporter plusieurs lèvres d'étanchéité décalées axialement. De même, la forme et la position de la lèvre d'étanchéité pourrait être différentes. Ainsi, même si la présente invention a été décrite en référence à un exemple de réalisation particulier, il est entendu qu'un homme du métier peut y apporter toutes modifications sans sortir du cadre de la présente invention tel que défini par les revendications annexées. As an alternative to the embodiment shown, the shell could have several sealing lips offset axially. Likewise, the shape and position of the sealing lip could be different. Thus, even if the present invention has been described with reference to a particular embodiment, it is understood that a person skilled in the art can make any modifications to it without departing from the scope of the present invention as defined by the appended claims.
