Abstract

The device of the invention permits the dispensing of measures of a given volume of a liquid contained in a deformable container. It provides increased safety. It comprises in particular a one-piece displaceable safety element (5) comprising an upper gripping part (6) having a transverse closing face (7), a hollow central part forming a valve (8) and a lower part (9) forming a slide and outlet orifice, also hollow. This safety element thus comprising an axial hollow (10) is mounted so as to slide axially on the tube (1) via its lower part (9) between two limimt positions where it may be held. In the lowre closed position where the central part (8) of the safety element (5) is active, it then prevents the passage of liquid from the container to the cup via the tube (1) and its feed and outlet holes (3). In the upper open position, where this passage is made possible via axial and lateral holes (11) in the lower part (9) and and axial hollow ( 10) with which they communicate, the central part (8) is then inactive, the upper gripping part (6) of the safety element (5) projects permanently, at least partially, from the cup, the safety element (5) being such that, once the cap has been removed by the user, the latter must, in order to be able to use the device for dispensing measures, deliberately move the safety element (5) from its lower closed position to its upper open position by activating the upper gripping part (6).

Description

L'invention concerne un dispositif de distribution de doses de volume donné d'un liquide contenu dans un conteneur déformable comportant un organe de sécurité.The invention relates to a device for dispensing doses of a given volume of a liquid contained in a deformable container comprising a safety member.

On connaît déjà un dispositif de distribution de doses de volume donné d'un liquide contenu dans un conteneur déformable, du type comportant d'une part une cuvette fixée dans le col du conteneur et dans le fond de laquelle existe un trou d'amenée du liquide et, d'autre part une tubulure logée intégralement dans la cuvette, fixée au fond et en communication avec le trou d'amenée par son extrémité inférieure, pourvue, à son extrémité supérieure d'un trou de sortie, le dispositif de distribution pouvant être protégé par un capuchon amovible. On peut se référer, notamment, au document FR 2 572 056. Bien que cela ne soit que peu probable, on peut craindre, avec un tel dispositif que l'utilisateur ayant enlevé le capuchon ne se rende pas compte que le dispositif est, dans cette situation, prêt à être utilisé.There is already known a device for dispensing doses of given volume of a liquid contained in a deformable container, of the type comprising on the one hand a bowl fixed in the neck of the container and in the bottom of which there is a hole for feeding the liquid and, on the other hand, a tube housed integrally in the bowl, fixed to the bottom and in communication with the supply hole by its lower end, provided, at its upper end with an outlet hole, the dispensing device being able to be protected by a removable cap. We can refer, in particular, to the document FR 2 572 056. Although this is only very unlikely, it is to be feared, with such a device that the user who has removed the cap may not realize that the device is, in this situation, ready to use.

On connaît d'autres variantes de réalisation de dispositifs de distribution de doses mais ils sont réalisés différemment et ne résolvent pas le problème posé (voir documents US-A-3 123 259, 3 120 910, 3 095 128, 3 252 634).Other variants of dose distribution devices are known, but they are produced differently and do not solve the problem posed (see documents US-A-3,123,259, 3,120,910, 3,095,128, 3,252,634).

L'invention vise donc à résoudre ce problème de sécurité.The invention therefore aims to solve this security problem.

A cet effet, l'invention propose un dispositif de sécurité du type mentionné précédemment qui comporte, en outre, un organe de sécurité déplaçable, monobloc, comprenant une partie supérieure de préhension, ayant une face de fermeture transversale, une partie médiane formant clapet, creuse et une partie inférieure formant coulisse et orifice de sortie également creuse, cet organe de sécurité comportant ainsi un creux axial étant monté à coulissement axial sur la tubulaire par sa partie inférieure, entre deux positions extrêmes où il peut se trouver maintenu à savoir d'une part une position inférieure de fermeture où la partie médiane de l'organe de sécurité est active et empêche le passage de liquide depuis le conteneur jusqu'à la cuvette via la tubulure et ses trous d'amenée et de sortie et, d'autre part, une position supérieure d'ouverture où ce passage est rendu possible via des lumières axiales et latérales de la partie inférieure et le creux axial avec lequel elles communiquent, la partie médiane étant alors inactive, la partie supérieure de préhension de l'organe de sécurité étant saillante, en permanence, au moins partiellement, de la cuvette, l'organe de sécurité étant tel qu'une fois le capuchon enlevé par l'utilisateur, ce dernier doit, pour pouvoir utiliser le dispositif de distribution de doses, faire passer volontairement l'organe de sécurité de sa position inférieure de fermeture à sa position supérieure d'ouverture en actionnant la partie supérieure de préhension.To this end, the invention provides a safety device of the type mentioned above which further comprises a movable, one-piece safety member, comprising an upper gripping part, having a transverse closing face, a middle part forming a valve, hollow and a lower part forming a slide and outlet hole also hollow, this safety member thus comprising an axial hollow being mounted to slide axially on the tubular by its lower part, between two extreme positions where it can be maintained, namely firstly a lower closed position where the middle part of the safety member is active and prevents the passage of liquid from the container to the bowl via the tubing and its inlet and outlet holes and, on the other hand, an upper opening position where this passage is made possible via axial and lateral openings in the lower part and the axial recess with which they communicate, the part median then being inactive, the upper gripping part of the safety member being protruding, permanently, at least partially, from the bowl, the safety member being such that once the cap has been removed by the user, this the latter must, in order to be able to use the dose distribution device, voluntarily move the safety member from its lower closed position to its upper open position by actuating the upper gripping part.

On connaît déjà, par ailleurs, des dispositifs formant clapet déplaçables coulissement axial (voir par exemple document FR 2 563 190). Mais de tels dispositifs ne sont pas adaptés pour être associés à des dispositifs de distribution tels que ceux mentionnés précédemment.Are already known, moreover, devices forming a valve which can be displaced axially sliding (see for example document FR 2 563 190). However, such devices are not suitable for being associated with distribution devices such as those mentioned above.

Les autres caractéristiques de l'invention résulteront de la description qui suivra en référence aux dessins annexés dans lesquels:

  • . Les figures 1 et 2 sont deux vues extérieures et en élévation du dispositif de distribution selon l'invention, représenté partiellement seulement (la cuvette, le conteneur, le capuchon n'étant pas représentés), respectivement en position inférieure de fermeture et en position supérieure d'ouverture.
  • . La figure 3 est une vue également partielle d'un dispositif de distribution selon l'invention en position supérieure d'ouverture, à l'extérieur et en élévation (demi-vue droite) et en coupe axiale (demi-vue gauche).

  • . Les figures 5 et 6 sont deux vues en coupe axiale de l'organe de sécurité et du manchon de guidage respectivement.
The other characteristics of the invention will result from the description which follows with reference to the accompanying drawings in which:
  • . Figures 1 and 2 are two exterior views and in elevation of the dispensing device according to the invention, shown only partially (the bowl, the container, the cap not being shown), respectively in the lower closed position and in the upper position opening hours.

L'invention concerne un dispositif de distribution de doses de volume donné d'un liquide contenu dans un conteneur déformable, du type général de celui décrit dans le document FR 2 572 056 auquel on peut se référer expressément. Pour cette raison, la structure générale d'un tel dispositif n'est pas de nouveau décrite ici en détail, la description étant limitée aux seuls moyens de sécurité additionnels.The invention relates to a device for dispensing volume doses. given of a liquid contained in a deformable container, of the general type of that described in document FR 2 572 056 to which one can expressly refer. For this reason, the general structure of such a device is not described again here in detail, the description being limited to only additional security means.

Pour mémoire, on se contente donc de rappeler qu'un tel dispositif de distribution est du type comportant d'une part une cuvette fixée dans le col du conteneur et dans le fond de laquelle existe un trou d'amenée du liquide et, d'autre part une tubulure 1 logée intégralement dans la cuvette, fixée au fond et en communication avec le trou d'amenée par son extrémité inférieure, pourvue, à son extrémité supérieure 2 d'un trou de sortie 3, le dispositif de distribution pouvant être protégé par un capuchon amovible. Le conteneur, son col, la cuvette et le capuchon amovible ne sont pas représentés sur les dessins.For the record, we are therefore content to recall that such a dispensing device is of the type comprising on the one hand a bowl fixed in the neck of the container and at the bottom of which there is a liquid supply hole and, on the other hand a tube 1 housed integrally in the bowl, fixed to the bottom and in communication with the supply hole by its lower end, provided, at its upper end 2 with an outlet hole 3, the dispensing device being able to be protected by a removable cap. The container, its neck, the bowl and the removable cap are not shown in the drawings.

Un tel dispositif de distribution est destiné, par exemple, à un liquide d'entretien ménager (de viscosité plus ou moins grande). Un tel conteneur avec son dispositif de distribution est destiné à être utilisé en étant d'axe 4 au moins sensiblement vertical, le dispositif de distribution étant en partie haute. Les indications figurant dans la description relativement aux qualificatifs "supérieur", "inférieur" ou équivalents, se réfèrent à cette position particulière d'utilisation. Toutefois, il est évident que le dispositif de distribution et le conteneur peuvent être placés dans d'autres positions, notamment horizontale, pour le stockage ou le transport par exemple.Such a dispensing device is intended, for example, for a household cleaning liquid (of greater or lesser viscosity). Such a container with its dispensing device is intended to be used with an axis 4 at least substantially vertical, the dispensing device being at the top. The indications appearing in the description relative to the qualifiers "superior", "inferior" or equivalent, refer to this particular position of use. However, it is obvious that the dispensing device and the container can be placed in other positions, in particular horizontal, for storage or transport for example.

Selon l'invention, le dispositif de distribution comporte, en outre, un organe de sécurité 5 déplaçable, monobloc, comprenant une partie supérieure de préhension 6, ayant une face de fermeture transversale 7, une partie médiane formant clapet 8, creuse et une partie inférieure 9 formant coulisse et orifice de sortie également creuse, cet organe de sécurité comportant ainsi un creux axial 10 étant monté à coulissement axial sur la tubulure 1 par sa partie inférieure 9, entre deux positions extrêmes où il peut se trouver maintenu à savoir d'une part une position inférieure de fermeture où la partie médiane 8 de l'organe de sécurité 5 est active et empêche le passage de liquide depuis le conteneur jusqu'à la cuvette via la tubulure 1 et ses trous d'amenée et de sortie 3 et, d'autre part, une position supérieure d'ouverture où ce passage est rendu possible via des lumières axiales et latérales 11 de la partie inférieure 9 et le creux axial 10 avec lequel elles communiquent, la partie médiane 8 étant alors inactive, la partie supérieure de préhension 6 de l'organe de sécurité 5 étant saillante, en permanence, au moins partiellement, de la cuvette, l'organe de sécurité 5 étant tel qu'une fois le capuchon enlevé par l'utilisateur, ce dernier doit pour pouvoir utiliser le dispositif de distribution de doses, faire passer volontairement l'organe de sécurité 5 de sa position inférieure de fermeture à sa position supérieure d'ouverture en actionnant la partie supérieure de préhension 6.According to the invention, the dispensing device further comprises a movable one-piece safety member 5, comprising an upper gripping part 6, having a transverse closing face 7, a central part forming a valve 8, hollow and a part lower 9 forming a slide and also hollow outlet orifice, this safety member thus comprising an axial recess 10 being mounted to slide axially on the tube 1 by its lower part 9, between two extreme positions where it can be maintained, namely on the one hand a lower closed position where the middle part 8 of the safety member 5 is active and prevents the passage of liquid from the container to the bowl via the tubing 1 and its inlet and outlet holes 3 and, on the other hand, an upper open position where this passage is made possible via axial and lateral lights 11 of the lower part 9 and the axial recess 10 with which they communicate, the middle part 8 then being inactive, the upper gripping part 6 of the safety member 5 being protruding, permanently, at least partially, from the bowl, the safety member 5 being such that once the cap has been removed by the user, the latter must, in order to be able to use the dose distribution device, voluntarily move the safety member 5 from its lower closed position to its upper position opening by actuating the upper gripping part 6.

Préférentiellement, l'organe de sécurité 5 est réalisé en matière plastique d'une seule pièce. Il a une forme générale extérieure au moins sensiblement pseudo-cylindrique, pseudo-conique ou tronconique, pseudo-prismatique, pseudo-pyramidale ou tronc de pyramide ou une combinaison de telles formes générales. En particulier, il présente un diamètre extérieur plus grand dans la partie inférieure 9 que dans la partie médiane 8. A cet effet, l'organe de sécurité 5 peut avoir une forme extérieure allant en s'élargissant de façon continue en ce qui concerne son diamètre extérieure, depuis son extrémité libre supérieure 12 de plus petit diamètre extérieur jusqu'à son extrémité libre inférieure 13 de plus grand diamètre extérieur.Preferably, the security member 5 is made of plastic in one piece. It has a general external shape at least substantially pseudo-cylindrical, pseudo-conical or frustoconical, pseudo-prismatic, pseudo-pyramidal or trunk of a pyramid or a combination of such general forms. In particular, it has a larger outside diameter in the lower part 9 than in the middle part 8. For this purpose, the safety member 5 can have an external shape which widens continuously as regards its outer diameter, from its upper free end 12 of smaller outside diameter to its lower free end 13 of larger outside diameter.

La partie supérieure de préhension 6 est en forme générale de tige, notamment creuse la face de fermeture transversale 7 étant située à son extrémité libre supérieure 12, la face latérale extérieure 14 de celle-ci étant pourvue, le cas échéant, de reliefs 15 d'accrochage facilitant la préhension. Par exemple, les reliefs 15 sont des saillies 15a et creux 15b alternés, s'étendant axialement.The upper gripping part 6 is generally in the form of a rod, in particular hollow the transverse closing face 7 being situated at its upper free end 12, the external lateral face 14 thereof being provided, where appropriate, with reliefs 15 d 'hooking facilitating gripping. For example, the reliefs 15 are alternating projections 15a and hollow 15b, extending axially.

Dans ce cas, l'organe de sécurité 5 est totalement creux. Le creux axial 10 est de diamètre intérieur plus grand dans la partie inférieure 9 que dans la partie médiane 8.In this case, the safety member 5 is completely hollow. The axial recess 10 has a larger internal diameter in the lower part 9 than in the middle part 8.

Par exemple et pour des utilisations tels que des liquides d'entretien ménager, la cuvette peut avoir, une longueur axiale de l'ordre de 3,5cm, et un diamètre de l'ordre de 3 cm. La tubulure 1 peut avoir une longueur axiale de l'ordre de 2,5cm et un diamètre extérieur de l'ordre de 0,75cm. L'organe de sécurité 5 peut avoir une longueur axiale de l'ordre de 4,5cm et un diamètre extérieur allant de l'ordre de 0,9cm à l'extrémité libre supérieure 12 à de l'ordre de 1,7cm à l'extrémité libre inférieure 13. Sa course axiale peut être de l'ordre de 0,7cm. Naturellement, ces valeurs ne sont que purement illustratives d'un exemple de réalisation particulier. Mais elles ne limitent pas la portée de l'invention.For example and for uses such as household cleaning liquids, the bowl may have an axial length of the order of 3.5 cm, and a diameter of the order of 3 cm. Tubing 1 can have an axial length of around 2.5 cm and an outside diameter of around 0.75 cm. The safety member 5 can have an axial length of the order of 4.5 cm and an outside diameter ranging from around 0.9 cm at the upper free end 12 to around 1.7 cm at 1 'lower free end 13. Its axial travel can be of the order of 0.7 cm. Naturally, these values are only purely illustrative of a particular embodiment. However, they do not limit the scope of the invention.

Dans la forme représentée, le trou de sortie 3 est latéral et la tubulure 1 comporte, à son extrémité supérieure 2 une face transversale libre 16 ce qui a pour effet que le jet de liquide issu du conteneur lorsqu'on le presse a un trajet en sortie de la tubulure 1 qui est transversal (c'est-à-dire sensiblement perpendiculaire à l'axe 4) et dirigé vers la paroi interne latérale 17 du creux 10 (et non axial).In the form shown, the outlet hole 3 is lateral and the tubing 1 has, at its upper end 2 a free transverse face 16 which has the effect that the jet of liquid from the container when it is pressed has a path in outlet of the pipe 1 which is transverse (that is to say substantially perpendicular to the axis 4) and directed towards the lateral internal wall 17 of the hollow 10 (and not axial).

Le clapet de la partie médiane 8 est constitué par sa face latérale intérieure 18 qui en position inférieure de fermeture coopère, avec étanchéité, avec la tubulure 1, en deçà de son trou de sortie 3. La face 18 fait partie de la paroi 17 et en constitue un tronçon axial de la partie médiane 8. Par exemple la face 18 est ajustée dimensionnellement pour coopérer avec frottement étanche sur un tronçon 19 de la face extérieure latérale de la tubulure 1 adjacent au trou 3 en direction opposée à la face transversale libre 16 (c'est-à-dire en direction du fond de la cuvette). Ce tronçon 19 peut avoir une certaine longueur axiale, de manière que l'étanchéité soit renforcée. En variantes, la face 18 peut avoir une légère conicité avec son sommet dirigé vers l'extrémité libre supérieure 12. Ou encore, elle peut présenter une ou plusieurs saillies périphériques internes 20 présentant par exemple une certain élasticité pour épouser le tronçon 19.The valve of the middle part 8 is constituted by its inner lateral face 18 which in the lower closed position cooperates, with sealing, with the tube 1, below its outlet hole 3. The face 18 forms part of the wall 17 and constitutes an axial section of the middle portion 8. For example the face 18 is dimensionally adjusted to cooperate with sealed friction on a section 19 of the lateral external face of the pipe 1 adjacent to the hole 3 in the direction opposite to the free transverse face 16 (i.e. towards the bottom of the bowl). This section 19 may have a certain axial length, so that the seal is reinforced. As a variant, the face 18 may have a slight taper with its apex directed towards the upper free end 12. Or, it may have one or more internal peripheral projections 20 having, for example, a certain elasticity to match the section 19.

En position supérieure d'ouverture, la tubulure 1 est essentiellement écartée radialement de la paroi 17 du creux 10. En particulier, la face 18 qui, en position de fermeture fait fonction de clapet est alors écartée axialement du tronçon 19 et, par exemple, située au moins sensiblement au dessus de la face transversale 16. En regard du trou de sortie 3 en sens transversal radial dans cette position d'ouverture la paroi 17 est écartée transversalement radialement ce qui ménage le passage pour l'écoulement du liquide. A cet effet, le tronçon axial de la paroi 17 au droit, en sens transversal radial, du trou de sortie 3, en position d'ouverture peut présenter une conicité dont le sommet est vers l'extrémité libre 12, ce qui favorise la réalisation du passage du liquide.In the upper open position, the tube 1 is essentially spaced radially from the wall 17 of the recess 10. In particular, the face 18 which, in the closed position acts as a valve is then spaced axially from the section 19 and, for example, located at least substantially above the transverse face 16. Opposite the outlet hole 3 in radial transverse direction in this open position, the wall 17 is spaced transversely radially which saves the passage for the flow of the liquid. To this end, the axial section of the wall 17 to the right, in radial transverse direction, of the outlet hole 3, in the open position may have a taper whose apex is towards the free end 12, which promotes the realization the passage of liquid.

Pour assurer le coulissement de l'organe de sécurité 5, le dispositif comporte un manchon 21 de guidage placé à l'extérieur autour et fixé rigidement à la tubulure 1 dans sa partie inférieure, ce manchon 21 comportant des reliefs de guidage axial et de blocage à coulissement de l'organe de sécurité 5 en position inférieure de fermeture et supérieure d'ouverture. Le manchon 21 comporte pour chaque lumière 11 de l'organe de sécurité 5 un relief en forme de saillie axiale 22a extérieure et à l'extrémité supérieure libre de cette dernière une saillie transversale extérieure 22b, cette saillie transversale extérieure 22b coopérant avec la lumière 11. La partie inférieure 9 comporte, à l'extrémité libre inférieure 13 une nervure périphérique extérieure 23. Les saillies transversales extérieures 22b du manchon 21 sont situées au moins sensiblement aux extrémités supérieures et inférieures 24, 25 de lumière 11 lorsque l'organe de sécurité 5 est respectivement en positions inférieure de fermeture et supérieure d'ouverture. L'organe de sécurité 5 est monté à force sur le manchon de guidage 21, les saillies transversales 22b ayant à cet effet de bords supérieurs 26 inclinés formant clapet. L'organe de sécurité 5 est monté à frottement doux sur le manchon de guidage 21. Par exemple, il est prévu quatre lumières 11 et quatre reliefs 22 disposés à 90° autour de l'axe 4. Toutefois, il peut être prévu un nombre différent de lumières 11 et de reliefs 22 dès lors que les fonctions de guidage à coulisement et de passage de liquide sont remplies.To ensure the sliding of the safety member 5, the device comprises a guide sleeve 21 placed outside around and rigidly fixed to the tube 1 in its lower part, this sleeve 21 comprising reliefs of axial guide and blocking sliding of the safety member 5 in the lower closed and upper open position. The sleeve 21 has, for each lumen 11 of the safety member 5, a relief in the form of an external axial projection 22a and at the free upper end of the latter an external transverse projection 22b, this external transverse projection 22b cooperating with the light 11 The lower part 9 comprises, at the lower free end 13 an external peripheral rib 23. The external transverse projections 22b of the sleeve 21 are located at least substantially at the upper and lower ends 24, 25 of lumen 11 when the safety member 5 is respectively in the lower closed and upper open positions. The safety member 5 is forcibly mounted on the guide sleeve 21, the transverse projections 22b having for this purpose inclined upper edges 26 forming a valve. The safety member 5 is mounted with gentle friction on the guide sleeve 21. For example, four slots 11 and four reliefs 22 are provided arranged at 90 ° around the axis 4. However, a number can be provided different from lights 11 and reliefs 22 as soon as the sliding guide and liquid passage functions are fulfilled.

Une lumière 11 a, en élévation, une forme générale rectangulaire étroite dont la longueur s'étend parallèlement à l'axe 4. La lumière 11 s'étand sur la partie inférieure 9 entre la nervure 23 et le raccordement avec la partie médiane 8. En position de fermeture, les lumières 11 sont situées radialement au droit du manchon 21. En position d'ouverture elles sont situées, substantiellement au dessus du manchon 21, au droit de la tubulure 1.A lumen 11 has, in elevation, a generally narrow rectangular shape whose length extends parallel to the axis 4. The lumen 11 extends over the lower part 9 between the rib 23 and the connection with the middle part 8. In the closed position, the openings 11 are located radially to the right of the sleeve 21. In the open position they are located, substantially above the sleeve 21, at the right of the pipe 1.

Le manchon 21 comporte essentiellement une paroi latérale 27, d'axe 4, fixée rigidement à la tubulure 1, paroi 27 sur laquelle s'étendent les reliefs 22.The sleeve 21 essentially comprises a side wall 27, of axis 4, rigidly fixed to the pipe 1, wall 27 on which the reliefs 22 extend.

En particulier, les saillies axiales 22a s'étendent sur la totalité ou presque totalité de la hauteur axiale du manchon 21. Et les saillies transversales 22b sont situées à l'endroit ou au voisinage du bord supérieur du manchon 21.In particular, the axial projections 22a extend over all or almost all of the axial height of the sleeve 21. And the transverse projections 22b are located at or near the upper edge of the sleeve 21.

Selon une autre caractéristique, les dimensions relatives en sens axial sont telles que lorsque le capuchon est placé sur le col du conteneur, dans son état de fermeture, il interfère avec l'organe de sécurité 5 pour que ce dernier soit en position inférieure de fermeture. En particulier la face transversale du capuchon vient en blocage sur l'extrémité libre supérieure 12.According to another characteristic, the relative dimensions in the axial direction are such that when the cap is placed on the neck of the container, in its closed state, it interferes with the safety member 5 so that the latter is in the lower closed position . In particular, the transverse face of the cap comes to lock on the upper free end 12.

Ainsi que cela résulte de ce qui précède, les lumières 11 participent, en combinaison avec les reliefs 22, au guidage de l'organe de sécurité 5 dans son mouvement de coulisement axial. Par ailleurs, elles permettent l'évacuation du liquide, en position d'ouverture de l'organe de sécurité 5.As follows from the above, the lights 11 participate, in combination with the reliefs 22, in guiding the safety member 5 in its axial sliding movement. Furthermore, they allow the evacuation of the liquid, in the open position of the safety member 5.
