Abstract

The invention concerns a device for dispensing a dose of liquid or gel products comprising a dispensing head axially mobile mounted on a product reservoir and provided with an outlet conduit and a metering chamber delimited by an intake valve and by a piston whereof the rod is connected to said head and which is equipped with an exhaust valve. The invention is characterized in that the rod of the piston extends inside the chamber through a projecting lower end providing sealed locking of the intake valve when the head is in low position.

Description

La présente invention conceme un dispositif pour le dosage d'un produit liquide ou en gel.The present invention relates to a device for the determination of a liquid or gel product.

Plus précisément, le dispositif de l'invention est du type comprenant une tête de distribution mobile axialement en coiffant un réservoir de produit et pourvue d'un conduit de sortie et une chambre de dosage délimitée, d'une part, par un clapet d'admission et, d'autre part, par un piston dont la tige est raccordée à ladite tête et qui est équipé d'un clapet d'échappement.More specifically, the device of the invention is of the type comprising a dispensing head axially movable by capping a product reservoir and provided with an outlet duct and a metering chamber delimited, on the one hand, by a flap valve. intake and, secondly, by a piston whose rod is connected to said head and which is equipped with an exhaust valve.

Cependant, les dispositifs de ce type sont complexes, en particulier du fait que le clapet d'échappement doit garantir et maintenir l'étanchéité de la chambre en partie supérieure, cette demière étant toujours remplie de produit lorsque le dispositif se trouve en position de repos.However, the devices of this type are complex, in particular because the exhaust valve must guarantee and maintain the tightness of the chamber in the upper part, the latter always being filled with product when the device is in the rest position. .

En outre, ces dispositifs comprennent généralement un organe de rappel de la tête en position haute constitué d'un ressort hélicoïdal métallique.In addition, these devices generally comprise a return member of the head in the high position consisting of a metal coil spring.

Ce ressort, outre, les problèmes de recyclabilité, est une pièce qu'il est difficile de positionner de façon fonctionnelle sans nuire à l'efficacité ou à l'encombrement du dispositif.This spring, besides the recyclability problems, is a piece that is difficult to position in a functional manner without affecting the efficiency or the size of the device.

EP 0 974 401 divulgue un dispositif de ce type, pourvu d'un ressort de rappel de la tête en position haute, dans lequel la tige du piston se prolonge à l'intérieur de la chambre par une extrémité inférieure en saillie assurant le verrouillage étanche du clapet d'admission en position basse de la tête et dans lequel la chambre est ménagée dans une douille cylindroconiqe pourvue d'une collerette supérieure d'accrochage sur le bord du réservoir.EP 0 974 401 discloses a device of this type, provided with a return spring of the head in the high position, in which the piston rod is extended inside the chamber by a projecting lower end ensuring the tight locking the intake valve in the low position of the head and wherein the chamber is formed in a cylindroconiqe sleeve provided with an upper catching collar on the edge of the tank.

Dans ce dispositif connu, la tête est retenue en position haute vis-à-vis d'une séparation par rapport au réservoir par une collerette.In this known device, the head is held in the upper position with respect to a separation relative to the reservoir by a flange.

La tête est retenue en position basse par un système à baïonnette qui est mis en oeuvre par un appui sur la tête et une rotation de cette demière. Toutefois, dans cette position basse, un léger débattement vertical de la tête est possible et l'étanchéité du verrouillage du clapet risque de ne pas être toujours assurée. De plus, lorsqu'elle est en position haute, la tête peut facilement être déplacée vers le bas, provoquant un actionnement intempestif du dispositif.The head is held in the low position by a bayonet system which is implemented by a support on the head and a rotation of the latter. However, in this low position, a slight vertical deflection of the head is possible and the sealing of the valve lock may not always be ensured. In addition, when it is in the high position, the head can easily be moved downwards, causing inadvertent actuation of the device.

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante.The present invention aims to solve these technical problems satisfactorily.

Ce but est atteint selon l'invention grâce au fait que la tête de distribution comporte une jupe latérale externe pourvue de premiers moyens de blocage susceptibles de coopérer par encliquetage avec des deuxièmes moyens de blocage inférieur ménagés sur ladite collerette pour bloquer la tête en position basse et susceptibles de coopérer avec des deuxièmes moyens de blocage supérieur pour retenir la tête en position haute, vis-à-vis d'un arrachement et au fait que le dispositif est exempt d'un moyen de rappel du déplacement de la tête de distribution.This object is achieved according to the invention by virtue of the fact that the dispensing head comprises an external lateral skirt provided with first locking means capable of cooperating by snapping with second lower locking means provided on said flange to lock the head in a low position. and capable of cooperating with second upper locking means for holding the head in the up position, with respect to a tearing and the fact that the device is free of a means for returning the displacement of the dispensing head.

Grâce à ces dispositions, même si, la tête étant en position haute, on exerçait un appui involontaire sur cette demière la conduisant à se déplacer vers le bas, elle serait automatiquement bloquée en position basse par un simple encliquetage, pour éviter un nouveau remplissage de la chambre de dosage.Thanks to these arrangements, even if, the head being in the up position, it was involuntarily pressed on the latter leading to move downwards, it would be automatically locked in the lower position by a simple snap, to avoid a new filling of the dosing chamber.

Avantageusement, les premiers moyens de blocage sont formés en partie inférieure de la jupe latérale externe.Advantageously, the first blocking means are formed in the lower part of the outer side skirt.

Avantageusement, les premiers moyens de blocage sont formés par une nervure de blocage, tandis que les deuxièmes moyens de blocage inférieur sont formés par un rétreint inférieur.Advantageously, the first locking means are formed by a locking rib, while the second lower locking means are formed by a lower necking.

Les deuxièmes moyens de blocage supérieurs sont quant à eux avantageusement formés par un jonc supérieur apte à retenir la nervure de blocage.The second upper locking means are advantageously formed by an upper ring adapted to retain the locking rib.

Cette nervure et ce jonc peuvent être dimensionnés pour générer, lors du coulissement de la jupe de la tête contre la collerette, des forces de frottement nécessitant l'application d'un effort minimum déterminé pour déplacer la tête.This rib and this ring can be sized to generate, during sliding of the skirt of the head against the collar, friction forces requiring the application of a minimum force determined to move the head.

En variante, les deuxièmes moyens de blocage supérieur peuvent coopérer par encliquetage avec les premiers moyens de blocage en position haute de la tête.As a variant, the second upper locking means can cooperate by snapping with the first locking means in the high position of the head.

Par exemple, ces deuxièmes moyens de blocage supérieur peuvent être formés par un rétreint supérieur, analogue au rétreint inférieur.For example, these second upper blocking means may be formed by an upper necking, similar to the lower necking.

De préférence, ladite collerette est pourvue d'un orifice d'évent éventuellement prolongé par une saignée ménagée sur la paroi exteme de la douille.Preferably, said collar is provided with a vent orifice possibly extended by a groove formed on the outer wall of the sleeve.

Dans ce cas, l'orifice d'évent est avantageusement disposé au travers d'un épaulement de liaison avec le corps de la douille. De plus, avantageusement, ladite tête comporte une paroi interne cylindrique, coaxiale avec ladite jupe, et destinée à obturer l'orifice d'évent en position basse de la tête.In this case, the vent orifice is advantageously disposed through a shoulder of connection with the body of the sleeve. In addition, advantageously, said head has a cylindrical inner wall, coaxial with said skirt, and intended to close the vent orifice in the lower position of the head.

Selon une autre caractéristique, la tige du piston comporte un conduit d'éjection axial débouchant, en partie haute, dans une cavité de ladite tête où est logé le clapet d'échappement.According to another characteristic, the piston rod comprises an axial ejection duct opening, at the top, in a cavity of said head where the exhaust valve is housed.

Selon une variante, ladite cavité est ménagée dans un manchon solidaire de la partie inférieure de la tête et raccordé coaxialement à l'extrémité supérieure de la tige du piston.According to a variant, said cavity is formed in a sleeve integral with the lower part of the head and coaxially connected to the upper end of the piston rod.

De préférence, la paroi supérieure de ladite cavité est pourvue de canaux communiquant avec le conduit de sortie du produit.Preferably, the upper wall of said cavity is provided with channels communicating with the product outlet duct.

Selon encore une autre caractéristique, le clapet d'admission comprend un tube axial en saillie à l'intérieur de la chambre et dans lequel vient s'engager l'extrémité inférieure de la tige du piston en position basse de la tête.According to yet another feature, the intake valve comprises an axial tube projecting inside the chamber and in which is engaged the lower end of the piston rod in the lower position of the head.

Selon une variante, la paroi latérale dudit tube comporte au moins une lumière pour le passage du produit.Alternatively, the side wall of said tube has at least one lumen for the passage of the product.

Selon une autre variante, le clapet d'admission et/ou le clapet d'échappement comprennent une bille mobile obturante.According to another variant, the intake valve and / or the exhaust valve comprise a movable ball shutter.

Le dispositif de l'invention s'affranchit par une structure simple constituée de peu de pièces d'un quelconque moyen de rappel du type ressort. Il est, en outre, facile à fabriquer, et donc fiable et économique.The device of the invention is overcome by a simple structure consisting of few parts of any spring type of return means. It is, moreover, easy to manufacture, and therefore reliable and economical.

Ce dispositif trouve aussi bien son application dans le domaine de la pharmacie où il peut permettre le dosage et la distribution notamment de sirops que dans le domaine des produits cosmétiques ou alimentaires.This device is equally applicable in the field of pharmacy where it can allow dosing and distribution including syrups in the field of cosmetics or food.

L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins, sur lesquels :

  • la figure 1 représente une vue en coupe d'un mode de réalisation du dispositif de l'invention.
  • Les figures 2A à 2D représentent des vues en coupe du dispositif de la figure 1, monté sur un réservoir de produit, pendant les différentes phases de la distribution.
The invention will be better understood on reading the description which follows with reference to the drawings, in which:
  • Figure 1 shows a sectional view of an embodiment of the device of the invention.
  • Figures 2A to 2D show sectional views of the device of Figure 1, mounted on a product reservoir, during the different phases of the distribution.

Le dispositif représenté sur la figure 1 est destiné au dosage de produits liquides ou en gel. A cet effet, le dispositif comprend une tête de distribution 1 mobile axialement en coiffant un réservoir R de produit (dont seul le col C est apparent sur la figure 1). La tête 1 est pourvue d'un conduit 11 de sortie du produit.The device shown in FIG. 1 is intended for the dosing of liquid or gel products. For this purpose, the device comprises a dispensing head 1 movable axially by capping a product tank R (of which only the neck C is apparent in Figure 1). The head 1 is provided with a conduit 11 of the product outlet.

Le dispositif comprend également une chambre de dosage 20 délimitée, d'une part, par un clapet d'admission 22 et, d'autre part, par un piston 3 dont la tige 31 est raccordée à la tête 1. Le piston 3 est équipé d'un clapet d'échappement 32.The device also comprises a metering chamber 20 delimited, on the one hand, by an inlet valve 22 and, on the other hand, by a piston 3 whose rod 31 is connected to the head 1. The piston 3 is equipped an exhaust valve 32.

Dans le mode de réalisation représenté, les clapets d'admission et d'échappement comprennent chacun une bille mobile obturante. La chambre 20 est ménagée ici dans une douille 2 à corps cylindroconique, pourvue d'une collerette supérieure 21 d'accrochage sur le bord du col C du réservoir.In the embodiment shown, the intake and exhaust valves each comprise a movable ball shutter. The chamber 20 is formed here in a sleeve 2 to cylindroconic body, provided with an upper collar 21 for hooking on the edge of the neck C of the tank.

La tige 31 du piston 3 se prolonge à l'intérieur de la chambre 20 par une extrémité inférieure 31 a en saillie qui assure le verrouillage du clapet d'admission 22, en position basse de la tête 1.The rod 31 of the piston 3 is extended inside the chamber 20 by a lower end 31a projecting which locks the inlet valve 22, in the lower position of the head 1.

La tête 1 comporte une jupe latérale externe 12 pourvue à sa partie inférieure d'une nervure de blocage 12a susceptible de coopérer avec deux butées de blocage ménagées sur la paroi exteme de la collerette 21.The head 1 comprises an outer lateral skirt 12 provided at its lower part with a locking rib 12a capable of cooperating with two locking stops provided on the outer wall of the collar 21.

Ces deux butées sont formées respectivement d'un jonc supérieur 21 a limitant la course de la tête vers le haut et d'un rétreint inférieur 21b assurant la retenue de la tête 1 en position basse par encliquetage amovible de la nervure 12a.These two stops are formed respectively of an upper ring 21a limiting the stroke of the head upwards and a lower necking 21b ensuring the retention of the head 1 in the low position by detachable snapping of the rib 12a.

La périphérie intérieure de la jupe 12 présente une gorge annulaire 12b dans laquelle pénètre par encliquetage le jonc 21 a en position basse de la tête 1.The inner periphery of the skirt 12 has an annular groove 12b into which the snap ring 21a snaps into the lower position of the head 1.

Dans cette position basse, l'extrémité 31 a du piston 31 peut très légèrement s'écraser élastiquement contre le clapet 22 et/ou le siège 2a du clapet 2 peut légèrement se déformer élastiquement pour assurer la fermeture étanche de ce clapet.In this low position, the end 31a of the piston 31 may very slightly crash resiliently against the valve 22 and / or the seat 2a of the valve 2 may slightly deform elastically to ensure the sealing of this valve.

Le déplacement axial de la tige 1 s'effectue par traction ou appui manuels en mode tiré-poussé en l'absence d'un quelconque moyen de rappel et de façon guidée par contact de glissement de la nervure 12a sur la paroi exteme de la collerette 21, entre les deux butées 21 a, 21 b.The axial displacement of the rod 1 is effected by pulling or manual support in pull-pushed mode in the absence of any return means and in a guided manner by sliding contact of the rib 12a on the outer wall of the collar 21, between the two stops 21 a, 21 b.

La collerette 21 est pourvue, le cas échéant, d'un orifice d'évent 210. Cet orifice est disposé au travers de l'épaulement 212 de liaison avec le corps de la douille 2.The flange 21 is provided, if necessary, with a vent orifice 210. This orifice is disposed through the shoulder 212 of connection with the body of the sleeve 2.

Lorsque le col C est emprisonné avec un léger serrage entre le corps de la douille 2 et la paroi latérale de la collerette 21, il est prévu de prolonger l'orifice 210 par une saignée verticale (non représentée) réalisée sur la paroi exteme du corps de la douille 2.When the neck C is trapped with a slight tightening between the body of the sleeve 2 and the side wall of the collar 21, it is intended to extend the orifice 210 by a vertical groove (not shown) made on the outer wall of the body of the socket 2.

Dans le mode de réalisation représenté, cette saignée n'est pas nécessaire du fait qu'il existe un espace intercalaire autorisant le passage de la reprise d'air dans le réservoir via l'orifice 210.In the embodiment shown, this bleeding is not necessary because there is an intermediate space allowing the passage of the return of air into the tank via the orifice 210.

De même, le très léger jeu existant entre la paroi interne de la jupe 12 et en particulier la nervure 12a, d'une part, et la paroi externe de la collerette 21, d'autre part, est suffisant pour permettre la reprise d'air.Similarly, the very slight clearance between the inner wall of the skirt 12 and in particular the rib 12a, on the one hand, and the outer wall of the collar 21, on the other hand, is sufficient to allow the recovery of air.

La tête 1 comporte une paroi interne cylindrique 14 située coaxialement et radialement à l'intérieur de la jupe 12 et destinée à obturer l'orifice d'évent 210 en position basse de la tête 1.The head 1 has a cylindrical inner wall 14 located coaxially and radially inside the skirt 12 and intended to close the vent orifice 210 in the lower position of the head 1.

A cet effet, la paroi 14 est disposée au droit de l'orifice 210 et son épaisseur est supérieure au diamètre de l'orifice 210.For this purpose, the wall 14 is disposed in line with the orifice 210 and its thickness is greater than the diameter of the orifice 210.

En position basse de la tête 1, la paroi dans laquelle est formé l'épaulement 212 peut légèrement se déformer élastiquement vers l'intérieur du récipient sous l'effet de la pression exercée par la paroi cylindrique 14 pour garantir l'obturation de l'évent 210.In the lower position of the head 1, the wall in which the shoulder 212 is formed may slightly deform elastically towards the inside of the container under the effect of the pressure exerted by the cylindrical wall 14 to guarantee the closure of the vent 210.

La tige 31 du piston 3 comporte, sur toute sa hauteur, un conduit d'éjection axial 30 débouchant, en partie haute, dans une cavité 10 de la tête 1 où est logé le clapet d'échappement 32 à bille. L'extrémité inférieure du conduit 30 délimite l'orifice d'évacuation du produit à partir de la chambre 20.The rod 31 of the piston 3 comprises, over its entire height, an axial ejection duct 30 opening, at the top, into a cavity 10 of the head 1 which houses the exhaust valve 32 ball. The lower end of the duct 30 delimits the outlet orifice of the product from the chamber 20.

La cavité 10 est ménagée dans un manchon 13 solidaire de la partie inférieure de la tête 1 et raccordé coaxialement à l'extrémité supérieure de la tige 31.The cavity 10 is formed in a sleeve 13 secured to the lower part of the head 1 and coaxially connected to the upper end of the rod 31.

La paroi supérieure de la cavité 10 est pourvue d'un réseau de canaux 10a communiquant avec le conduit 11 de sortie du produit et permettant le passage du produit lorsque la bille du clapet 32 est plaquée contre ladite paroi en phase de distribution (voir figure 2C) sous la pression du produit éjecté.The upper wall of the cavity 10 is provided with a network of channels 10a communicating with the outlet duct 11 of the product and allowing the passage of the product when the ball of the valve 32 is pressed against said wall in the distribution phase (see Figure 2C) under the pressure of the ejected product.

La clapet d'admission 22 comprend un tube axial 23 qui fait saillie à l'intérieur de la chambre 20 et dans lequel vient s'engager l'extrémité inférieure 31 a de la tige 31 du piston 3 en position basse de la tête 1.The intake valve 22 comprises an axial tube 23 which projects inside the chamber 20 and into which the lower end 31a of the rod 31 of the piston 3 engages in the lower position of the head 1.

Cet engagement, qui s'effectue sans serrage radial, est poursuivi jusqu'à mise en appui de l'extrémité 31a de la tige 31 contre la bille du clapet 22. Le verrouillage du clapet dans cette position d'étanchéité correspondant au calage de la bille dans le fond du tube 23 est garanti par encliquetage de la nervure 12a dans le rétreint 21 b de la collerette 21 comme représenté sur les figures 2A et 2D.This engagement, which occurs without radial clamping, is continued until the end 31a of the rod 31 bears against the ball of the valve 22. The locking of the valve in this sealing position corresponding to the setting of the ball in the bottom of the tube 23 is guaranteed by snapping of the rib 12a in the necking 21 b of the flange 21 as shown in Figures 2A and 2D.

La paroi latérale du tube 23 comporte au moins une lumière 23a permettant le passage transversal du produit en phase de remplissage de la chambre par montée de la tête 1 et aspiration du produit comme représenté sur la figure 2B.The side wall of the tube 23 comprises at least one slot 23a allowing the transverse passage of the product in the filling phase of the chamber by mounting the head 1 and suction of the product as shown in Figure 2B.
