Description

La présente invention a pour objet un dispositif de distribution d'un produit liquide.The present invention relates to a device for dispensing a liquid product.

Plus précisément, elle a pour objet un dispositif de distribution d'un produit liquide comprenant un récipient muni à sa partie supérieure d'un organe de distribution actionnable par enfoncement, un capot coiffant l'organe de distribution et le récipient, un organe d'actionnement en forme de levier étant articulé sur l'avant du capot, ledit organe d'actionnement permettant de réaliser à volonté l'enfoncement nécessaire au fonctionnement dudit organe de distribution, ledit capot comportant également sur sa face avant une buse de distribution alimentée par un canal de distribution prévu dans ledit capot et ayant au moins deux portions d'extrémités dont l'une alimente directement la buse de distribution et dont l'autre s'étend axialement, un moyen de raccordement muni d'un passage étant prévu entre l'organe de distribution et l'autre extrémité du canal de distribution qui s'étend axialement, ledit organe d'actionnement coopérant avec ledit moyen de raccordement pour réaliser l'enfoncement nécessaire au fonctionnement dudit organe de distribution.More specifically, it relates to a device for dispensing a liquid product comprising a container provided at its upper part with a dispensing member operable by pressing in, a cover covering the dispensing member and the container, a member for actuation in the form of a lever being articulated on the front of the cover, said actuation member making it possible to achieve at will the depression necessary for the operation of said distribution member, said cover also comprising on its front face a distribution nozzle supplied by a distribution channel provided in said cover and having at least two end portions, one of which directly feeds the distribution nozzle and the other of which extends axially, a connection means provided with a passage being provided between the distribution member and the other end of the distribution channel which extends axially, said actuating member cooperating with said connection means for r carry out the insertion necessary for the operation of said dispensing member.

Un tel dispositif est, par exemple, décrit dans FR-A-2 682 937 ; il présente l'avantage que, la buse de distribution étant portée par le capot, il n'est pas nécessaire de prévoir une échancrure dans le capot, comme c'est le cas lorsque la buse de distribution est portée par une tête de distribution qui est déplacée axialement, par rapport au capot, telle que celle décrite dans FR-A-2 675 403 ; l'échancrure dans le capot nécessite un positionnement de celui-ci par rapport au récipient, même lorsque la tête de distribution est centrée par rapport au récipient, et risque, en outre, d'affaiblir la tenue mécanique dudit capot.Such a device is, for example, described in FR-A-2 682 937; it has the advantage that, the dispensing nozzle being carried by the cover, it is not necessary to provide a notch in the cover, as is the case when the dispensing nozzle is carried by a dispensing head which is moved axially, relative to the cover, such as that described in FR-A-2 675 403; the indentation in the cover requires positioning of the latter relative to the container, even when the dispensing head is centered relative to the container, and risks, moreover, weakening the mechanical strength of said cover.

Malheureusement, le dispositif tel que décrit dans FR-A-2 682 937 présente l'inconvénient suivant: le moyen de raccordement prévu entre l'organe de distribution et le canal de distribution est solidaire de ceux-ci pour des raisons d'étanchéité, mais doit être prévu flexible du fait que le canal de distribution est porté par une partie déformable du capot solidaire de l'organe d'actionnement ; dès lors, la flexibilité toute relative du moyen de raccordement conduit à des sollicitations transversales de l'organe de distribution.Unfortunately, the device as described in FR-A-2 682 937 has the following drawback: the connection means provided between the distribution member and the distribution channel is integral with the latter for sealing reasons, but must be provided flexible because the distribution channel is carried by a deformable part of the cover secured to the actuating member; therefore, the relative flexibility of the connection means leads to transverse stresses on the dispensing member.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Ainsi, selon l'invention, un dispositif de distribution d'un produit liquide comprenant un récipient muni à sa partie supérieure d'un organe de distribution actionnable par enfoncement, un capot coiffant l'organe de distribution et le récipient, un organe d'actionnement en forme de levier étant articulé sur l'avant du capot, ledit organe d'actionnement permettant de réaliser à volonté l'enfoncement nécessaire au fonctionnement dudit organe de distribution, ledit capot comportant également sur sa face avant une buse de distribution alimentée par un canal de distribution prévu dans ledit capot et ayant au moins deux portions d'extrémités dont l'une alimente directement la buse de distribution et dont l'autre s'étend axialement, un moyen de raccordement muni d'un passage étant prévu entre l'organe de distribution et l'autre extrémité du canal de distribution qui s'étend axialement, ledit organe d'actionnement coopérant avec ledit moyen de raccordement pour réaliser l'enfoncement nécessaire au fonctionnement dudit organe de distribution, est caractérisé par le fait que le moyen de raccordement est raccordé de façon étanche à l'extrémité axiale du canal de distribution par rapport à laquelle il est déplaçable axialement.Thus, according to the invention, a device for dispensing a liquid product comprising a container provided at its upper part with a dispensing member actuable by pressing in, a cover covering the dispensing member and the container, a member for actuation in the form of a lever being articulated on the front of the cover, said actuation member making it possible to achieve at will the depression necessary for the operation of said distribution member, said cover also comprising on its front face a distribution nozzle supplied by a distribution channel provided in said cover and having at least two end portions, one of which directly feeds the distribution nozzle and the other of which extends axially, a connection means provided with a passage being provided between the distribution member and the other end of the distribution channel which extends axially, said actuating member cooperating with said connection means to produce the depression necessary for the operation of said dispensing member, is characterized in that the connection means is tightly connected to the axial end of the dispensing channel with respect to which it is axially displaceable.

Avantageusement, le moyen de raccordement comporte à sa partie supérieure un embout cylindrique monté à coulissement de façon étanche dans l'extrémité axiale à section correspondante du canal de distribution ; le moyen de raccordement comporte à sa partie inférieure un logement cylindrique avec lequel coopère de façon étanche, et en butée axiale, l'organe de distribution.Advantageously, the connection means comprises at its upper part a cylindrical end piece slidingly mounted in leaktight manner in the axial end with corresponding section of the distribution channel; the connection means comprises at its lower part a cylindrical housing with which cooperates sealingly, and in axial abutment, the dispensing member.

Selon une variante de réalisation, l'organe de distribution est une pompe montée sur la partie supérieure du récipient et dont la tige de manoeuvre est emmanchée dans le logement cylindrique du moyen de raccordement.According to an alternative embodiment, the dispensing member is a pump mounted on the upper part of the container and the operating rod of which is fitted into the cylindrical housing of the connection means.

Selon une autre variante, l'organe de distribution est une valve montée sur la partie supérieure du récipient et dont la tige de manoeuvre est emmanchée dans le logement cylindrique du moyen de raccordement.According to another variant, the dispensing member is a valve mounted on the upper part of the container and the stem of which maneuver is fitted into the cylindrical housing of the connection means.

De préférence, le moyen de raccordement comporte une collerette circulaire avec laquelle coopère l'organe d'actionnement en forme de levier.Preferably, the connection means comprises a circular collar with which the lever-shaped actuating member cooperates.

L'organe d'actionnement est articulé sur l'avant du capot au moyen d'une charnière-film, l'organe d'actionnement et le capot étant venus ensemble de moulage. En variante, l'organe d'actionnement est relié à l'avant du capot au moyen d'une charnière à tourillons ou de toute autre charnière, le capot et l'organe d'actionnement étant réalisés en deux pièces distinctes.The actuator is articulated on the front of the cover by means of a film hinge, the actuator and the cover having come together to be molded. As a variant, the actuating member is connected to the front of the cover by means of a journal hinge or any other hinge, the cover and the actuating member being produced in two separate parts.

Avantageusement, l'embout cylindrique du moyen de raccordement porte une lèvre d'étanchéité venue de moulage avec le moyen de raccordement.Advantageously, the cylindrical end piece of the connection means carries a sealing lip molded with the connection means.

L'organe de distribution est monté excentré par rapport à l'axe longitudinal du récipient, des moyens d'orientation angulaire étant prévus pour positionner le capot relativement à l'organe de distribution, donc au récipient ; les moyens d'orientation sont constitués par la forme de la section transversale du récipient et du capot.The dispensing member is mounted offset from the longitudinal axis of the container, angular orientation means being provided for positioning the cover relative to the dispensing member, therefore to the container; the orientation means are constituted by the shape of the cross section of the container and the cover.

En variante, l'organe de distribution est centré sur l'axe longitudinal du récipient.Alternatively, the dispensing member is centered on the longitudinal axis of the container.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire, maintenant, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur les dessins annexés.To better understand the object of the invention, we will now describe, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawings.

En se reportant aux figures 1 à 4, un dispositif de distribution d'un produit liquide comprend un récipient 2 muni à sa partie supérieure d'un organe de distribution 3 constitué d'une pompe dont on voit en 31 la tige de manoeuvre ; la pompe 3 et le récipient 2 sont coiffés d'un capot 1 ; des godrons d'accrochage 21, 22, complémentaires, sont portés respectivement par le capot 1 et le récipient 2 à leur périphérie, pour maintenir axialement le capot 1 sur le récipient 2.Referring to Figures 1 to 4, a device for dispensing a liquid product comprises a container 2 provided at its upper part with a dispensing member 3 consisting of a pump, the operating rod of which can be seen at 31; the pump 3 and the container 2 are capped with a cover 1; hooking flutes 21, 22, complementary, are carried respectively by the cover 1 and the container 2 at their periphery, in order to maintain the cover 1 axially on the container 2.

Le capot 1 comprend une paroi cylindrique 11 qui comporte sur sa face avant une buse de distribution 4, associée comme connu en soi à un pion de centrage 16 ménagé dans un pilier transversal 12 supportant un guide axial 13, le pilier 12 et le guide 13 étant venus de moulage avec le capot 1 ; le guide axial 13 est muni d'un alésage 14 cylindrique, à section circulaire, ouvert à son extrémité inférieure, et dont l'axe est parallèle à l'axe longitudinal du récipient 2 et du capot 1, et confondu avec celui de la tige 31 de la pompe 3 ; un passage transversal 15 fait communiquer la buse de distribution 4 avec l'alésage 14 : ainsi, un canal de distribution pour la buse 4 est constitué par le passage 15 et l'alésage 14. Un moyen de raccordement 6 est prévu entre ce canal de distribution 14-15 et la pompe 3.The cover 1 comprises a cylindrical wall 11 which has on its front face a dispensing nozzle 4, associated as known per se with a centering pin 16 formed in a transverse pillar 12 supporting an axial guide 13, the pillar 12 and the guide 13 having come from molding with the cover 1; the axial guide 13 is provided with a cylindrical bore 14, of circular section, open at its lower end, and whose axis is parallel to the longitudinal axis of the container 2 and of the cover 1, and coincides with that of the rod 31 of pump 3; a transverse passage 15 communicates the distribution nozzle 4 with the bore 14: thus, a distribution channel for the nozzle 4 is constituted by the passage 15 and the bore 14. A connection means 6 is provided between this channel distribution 14-15 and pump 3.

Ce moyen de raccordement 6 comporte à sa partie inférieure un logement cylindrique 65 ménagé dans sa partie inférieure 61 et dans lequel est emmanchée de façon étanche la tige de manoeuvre 31 de la pompe 3, qui, comme on le sait, est creusée d'un passage 32 ; une butée axiale 67 portée par le moyen de raccordement 6 coopère avec l'extrémité de la tige 31, de sorte qu'une action verticale sur le moyen de raccordement 6, comme décrit ci-dessous, est transmise à la tige de manoeuvre 31 de la pompe 3.This connection means 6 comprises at its lower part a cylindrical housing 65 formed in its lower part 61 and in which is tightly fitted the operating rod 31 of the pump 3, which, as is known, is hollowed out with a passage 32; an axial stop 67 carried by the connection means 6 cooperates with the end of the rod 31, so that a vertical action on the connection means 6, as described below, is transmitted to the operating rod 31 of pump 3.

Le moyen de raccordement 6 comporte à sa partie supérieure un embout cylindrique 63 à section circulaire monté à coulissement, de façon étanche, dans l'alésage 14 du guide axial 13 ; l'étanchéité est assurée par une lèvre 66 périphérique, mieux visible sur la figure 4, ménagée à la surface extérieure de l'embout 63 et venue de moulage avec le moyen de raccordement 6.The connection means 6 comprises at its upper part a cylindrical end piece 63 of circular section mounted to slide, in leaktight manner, in the bore 14 of the axial guide 13; sealing is ensured by a peripheral lip 66, better visible in FIG. 4, formed on the outer surface of the endpiece 63 and molded with the connection means 6.

Le moyen de raccordement 6 est traversé par un passage 64 ; ainsi, lorsque l'ensemble est monté, le passage 32 de la tige creuse 31 de la pompe 3 est relié en permanence à la buse de distribution 4, via le passage 64, l'alésage 14, et le passage 15.The connection means 6 is crossed by a passage 64; thus, when the assembly is mounted, the passage 32 of the hollow rod 31 of the pump 3 is permanently connected to the dispensing nozzle 4, via the passage 64, the bore 14, and the passage 15.

Le dispositif de distribution comprend également un organe d'actionnement en forme de levier 5 ; le levier 5 est articulé sur l'avant du capot 1, légèrement au dessus de la buse de distribution 4 : dans l'exemple représenté, cette articulation est réalisée par des charnières-film 51, le levier 5 et le capot 1 étant moulés ensemble d'une seule pièce ; bien entendu, l'articulation peut être réalisée autrement, le capot 1 et le levier 5 étant deux pièces distinctes, indépendantes.The dispensing device also comprises a lever-shaped actuating member 5; the lever 5 is articulated on the front of the cover 1, slightly above the dispensing nozzle 4: in the example shown, this articulation is produced by film hinges 51, the lever 5 and the cover 1 being molded together in one piece; of course, the articulation can be achieved otherwise, the cover 1 and the lever 5 being two separate, independent parts.

Le levier 5 a une forme générale de L ayant une aile 56 pratiquement transversale lorsque le dispositif est au repos, qui ferme la partie supérieure du capot 1, et une aile axiale 57, reliées par une paroi en secteurs 55 : le capot 1 présente une échancrure 17 facilitant la préhension du levier 5, la paroi en secteurs 55 fermant en quelque sorte l'ouverture créée par l'échancrure 17.The lever 5 has a general shape of L having a substantially transverse wing 56 when the device is at rest, which closes the upper part of the cover 1, and an axial wing 57, connected by a wall in sectors 55: the cover 1 has a indentation 17 facilitating the gripping of the lever 5, the wall in sectors 55 in a way closing the opening created by the indentation 17.

Le levier 5 constitue un organe d'actionnement pour l'enfoncement de la tige de manoeuvre 31 de la pompe 3 pour la mise en oeuvre de celle-ci. A cet effet, l'aile 56 du levier 5 porte deux cames 52 s'étendant dans deux plans parallèles entre eux et parallèles à l'axe longitudinal du dispositif de distribution ; les deux cames 52 sont placées de part et d'autre du guide axial 13 ; les profils 53 des cames 52 coopèrent en fonctionnement avec une collerette circulaire 62 transversale portée par le moyen de raccordement 6 et placée axialement entre l'embout 63 du moyen de raccordement 6 et sa partie inférieure 61 qui porte le logement cylindrique 65. L'aile 56 du levier 5 est munie d'une échancrure 54 permettant le passage du pilier 12 lors du débattement du levier 5 autour de son articulation 51.The lever 5 constitutes an actuating member for the insertion of the operating rod 31 of the pump 3 for the implementation of the latter. To this end, the wing 56 of the lever 5 carries two cams 52 extending in two planes parallel to each other and parallel to the longitudinal axis of the dispensing device; the two cams 52 are placed on either side of the axial guide 13; the profiles 53 of the cams 52 cooperate in operation with a circular circular collar 62 carried by the connection means 6 and placed axially between the end piece 63 of the connection means 6 and its lower part 61 which carries the cylindrical housing 65. The wing 56 of the lever 5 is provided with a notch 54 allowing passage of the pillar 12 during the movement of the lever 5 around its articulation 51.

Ainsi, une action sur le levier 5 fait basculer celui-ci autour de son articulation 51, comme montré à la figure 2 : les profils 53 des cames 52, en coopérant avec la collerette 62 du moyen de raccordement 6, exercent une action sur la tige 31 de la pompe 3, action transmise par la butée 67 ; lorsque l'action sur le levier 5 est relachée, le ressort de rappel, non représenté, associé à la tige 31 et prévu dans la pompe 3, comme cela est connu, rappelle le moyen de raccordement 6 et donc le levier 5 vers la position représentée à la figure 1 : en répétant l'action décrite ci-dessus sur le levier 5, la pompe 3 est mise en oeuvre et du liquide est distribué à travers la buse 4.Thus, an action on the lever 5 switches it around its articulation 51, as shown in FIG. 2: the profiles 53 of the cams 52, by cooperating with the flange 62 of the connection means 6, exert an action on the rod 31 of the pump 3, action transmitted by the stop 67; when the action on the lever 5 is released, the return spring, not shown, associated with the rod 31 and provided in the pump 3, as is known, recalls the connection means 6 and therefore the lever 5 towards the position represented in the FIG. 1: by repeating the action described above on the lever 5, the pump 3 is implemented and liquid is distributed through the nozzle 4.

Grâce à l'invention, le moyen de raccordement 6 étant guidé axialement en permanence dans le guide axial 13, les composantes transversales des efforts sur la tige 31 sont minimisés et conduisent à un bon fonctionnement de la pompe 3 en assurant à celle-ci une grande longévité ; les composantes transversales des efforts sur la tige 31 peuvent être encore réduites si, avantageusement, les profils 53 des cames 52 sont des profils en développantes de cercle, ces cercles étant centrés sur l'articulation 51 du levier 5, les points les plus bas de chacun des profils 53 des cames 52, au contact de la collerette 62, étant situés dans un même plan passant par l'axe de la tige 31 et du moyen de raccordement 6 : le point d'application des efforts transmis par les deux cames 52 est dès lors sur l'axe de la tige 31.Thanks to the invention, the connection means 6 being guided axially permanently in the axial guide 13, the transverse components of the forces on the rod 31 are minimized and lead to a good operation of the pump 3 by ensuring that it great longevity; the transverse components of the forces on the rod 31 can be further reduced if, advantageously, the profiles 53 of the cams 52 are profiles of involutes of a circle, these circles being centered on the articulation 51 of the lever 5, the lowest points of each of the profiles 53 of the cams 52, in contact with the flange 62, being located in the same plane passing through the axis of the rod 31 and of the connection means 6: the point of application of the forces transmitted by the two cams 52 is therefore on the axis of the rod 31.

Selon la variante qui vient d'être décrite, la pompe 3 est montée excentrée par rapport à l'axe longitudinal du récipient 2 : dès lors, le capot 1 doit être orienté pour positionner correctement le capot 1 et le guide axial 13 ainsi que le levier 5 par rapport à la pompe 3, donc au récipient 2 ; ceci est obtenu en donnant une forme particulière à la section transversale du récipient 2 et du capot 1 ; cette forme est par exemple oblongue comme cela est partiellement visible sur la figure 2.According to the variant which has just been described, the pump 3 is mounted eccentric with respect to the longitudinal axis of the container 2: therefore, the cover 1 must be oriented to correctly position the cover 1 and the axial guide 13 as well as the lever 5 relative to the pump 3, therefore to the container 2; this is obtained by giving a particular shape to the cross section of the container 2 and of the cover 1; this shape is for example oblong as is partially visible in FIG. 2.

Selon la variante de la figure 5, l'organe de distribution est centré sur l'axe longitudinal du récipient : selon cette variante, un récipient 102, de révolution, porte à l'intérieur un organe de distribution constitué d'une valve de distribution dont on voit en 131 la tige de manoeuvre ; le pilier 112 porté par le capot 101 et supportant le guide 113 est plus long que précédemment ; le levier 105 agit, comme précédemment, sur le moyen de raccordement 6 qui actionne la tige 131 de valve ; le fluide sous pression contenu dans le récipient 102 permet la distribution du liquide à travers la buse 104. Selon cette variante, le récipient 102 et le capot 101 sont de révolution et, comme on le voit, il n'est pas nécessaire de prévoir des moyens d'indexation du capot 101 par rapport au récipient 102.According to the variant of FIG. 5, the dispensing member is centered on the longitudinal axis of the container: according to this variant, a container 102, of revolution, carries inside a dispensing member consisting of a dispensing valve of which we see in 131 the operating rod; the pillar 112 carried by the cover 101 and supporting the guide 113 is longer than previously; the lever 105 acts, as before, on the connection means 6 which actuates the valve stem 131; the pressurized fluid contained in the container 102 allows the distribution of the liquid through the nozzle 104. According to this variant, the container 102 and the cover 101 are of revolution and, as can be seen, it is not necessary to provide means for indexing the cover 101 relative to the container 102.
