Description

La présente invention a pour objet un dispositif doseur adaptable sur des contenants divers rigides ou souples tels que flacons, tubes ou pots, utilisés notamment dans le domaine de la pharmacie, de la cosmétologie ou de l'industrie alimentaire.The present invention relates to a metering device adaptable to various rigid or flexible containers such as bottles, tubes or jars, used in particular in the field of pharmacy, cosmetology or the food industry.

Il existe à ce jour divers types de dispositifs doseurs qui mettent tous en oeuvre un certain nombre de pièces telles que ressorts, billes, clapets, bouchons et autres. Outre que la fabrication et l'assemblage de ces pièces sont onéreux en main d'oeuvre, ces dispositifs présentent généralement l'inconvénient d'une étanchéité insuffisante ainsi que d'une reprise d'air extérieur vers l'intérieur pendant leur ouverture et leur fermeture, ce qui nécessite d'incorporer des conservateurs au contenu afin d'éviter son oxydation.To date, there are various types of metering devices which all use a certain number of parts such as springs, balls, valves, plugs and the like. In addition to the fact that the manufacture and assembly of these parts are expensive in terms of labor, these devices generally have the drawback of an insufficient seal as well as of an intake of outside air towards the inside during their opening and their closure, which requires incorporating preservatives into the contents in order to avoid its oxidation.

Pour pallier ces inconvénients, les demandeurs ont proposé dans le brevet français FR-A-2.674.024 un dispositif doseur comprenant une pièce intérieure en matériau déformable élastique qui, lorsqu'on appuie sur le poussoir du contenant, se déforme et permet l'expulsion d'une dose du contenu et qui, en reprenant sa forme initiale, crée une dépression permettant par aspiration de recréer une dose dans une chambre dose, le contenu aspiré passant par un clapet constitué dans la pièce intérieure déformable et relié à celle-ci par un pont de matière.To overcome these drawbacks, the applicants have proposed in French patent FR-A-2,674,024 a metering device comprising an inner part made of elastic deformable material which, when the pusher of the container is pressed, deforms and allows expulsion of a dose of the content and which, by resuming its initial form, creates a depression allowing by suction to recreate a dose in a dose chamber, the sucked content passing through a valve formed in the deformable inner part and connected to it by a bridge of matter.

Ce dispositif présente toutefois l'inconvénient de ne pas permettre le dosage de produits de haute viscosité. En outre la pièce élastique a parfois des difficultés à reprendre sa forme et sa place initiales, ce qui peut occasionner une certaine reprise d'air extérieur.However, this device has the drawback of not allowing the dosing of high viscosity products. In addition, the elastic piece sometimes has difficulties in resuming its original shape and place, which can cause a certain recovery of outside air.

La présente invention vise à remédier à ces divers inconvénients en proposant un dispositif doseur qui permet de doser toutes sortes de produits, même de haute viscosité, avec une plus grande fiabilité, notamment au plan de l'étanchéité, et qui permet en outre de créer des doses de volume important.The present invention aims to remedy these various drawbacks by proposing a metering device which makes it possible to meter all kinds of products, even of high viscosity, with greater reliability, in particular in terms of sealing, and which also makes it possible to create large volume doses.

Le dispositif objet de la présente invention se caractérise essentiellement en ce qu'il comprend en combinaison :

  • a) un bouton poussoir abritant une chambre-dose délimitée par une paroi périphérique et une paroi supérieure, et traversée centralement par un tube qui communique avec l'ouverture d'expulsion, et qui est percé radialement, à proximité de son extrémité inférieure, d'au moins une ouverture ;
  • b) un support adaptable sur le contenant, sur lequel s'adapte et peut coulisser axialement le bouton poussoir, et dont la partie supérieure est fermée par une paroi qui comporte une ouverture centrale permettant le passage du tube du bouton poussoir et au moins un orifice, d'axe parallèle à ladite ouverture, pratiqué en périphérie dudit support ;
  • c) une pièce en matériau déformable élastique, disposée entre le bouton poussoir et le support, comprenant une partie tubulaire extensible fermée à sa base par une paroi et abritant le tube du bouton poussoir, dont l'extrémité inférieure vient en appui contre ladite paroi, et comprenant également, autour du bord supérieur de ladite partie tubulaire, une collerette apte à s'insérer dans la paroi supérieure du support en obturant le ou les orifices périphériques de ladite paroi, ladite collerette comportant à sa face supérieure une gorge annulaire bordée extérieurement par une lèvre qui s'applique contre la face interne de la paroi extérieure du bouton poussoir, ladite collerette étant apte à se déformer pour libérer ledit ou lesdits orifices périphériques de la paroi supérieure dudit support.
The device which is the subject of the present invention is essentially characterized in that it comprises in combination:
  • a) a push button housing a dose chamber delimited by a peripheral wall and an upper wall, and traversed centrally by a tube which communicates with the expulsion opening, and which is drilled radially, near its lower end, d '' at least one opening;
  • b) an adaptable support on the container, on which the push button fits and can slide axially, and the upper part of which is closed by a wall which has a central opening allowing the passage of the push button tube and at least one orifice , with an axis parallel to said opening, made on the periphery of said support;
  • c) a piece of elastic deformable material, disposed between the push button and the support, comprising an expandable tubular part closed at its base by a wall and housing the push button tube, the lower end of which bears against said wall, and also comprising, around the upper edge of said tubular part, a collar capable of being inserted into the upper wall of the support by closing the peripheral orifice (s) of said wall, said collar comprising on its upper face an annular groove bordered externally by a lip which is applied against the internal face of the external wall of the push button, said flange being able to deform to release said one or more peripheral orifices from the upper wall of said support.

Le fonctionnement du dispositif selon l'invention est le suivant: une pression sur le bouton poussoir fait coulisser celui-ci sur le support, ce qui a pour effet de comprimer, entre la paroi supérieure du bouton poussoir et la collerette de la pièce en matériau déformable, le produit contenu dans la chambre-dose, lequel passe entre le tube et la partie tubulaire de ladite pièce, s'échappe par le ou les orifices pratiqués radialement dans le tube et remonte dans celui-ci jusqu'à l'ouverture d'expulsion, après quoi la partie tubulaire de ladite pièce, qui a été étirée, reprend sa forme initiale, d'une part en provoquant la remontée du bouton poussoir et en osbtruant le ou lesdits orifices radiaux, empêchant de ce fait la reprise d'air ou le retour du produit contenu dans le tube ; et d'autre part en provoquant l'aspiration dans la chambre-dose du produit du contenant, qui passe par le ou les orifices périphériques de la paroi supérieure du support en repoussant la collerette et en passant entre la lèvre périphérique et la face interne de la paroi du bouton poussoir.The operation of the device according to the invention is as follows: a pressure on the push button slides it on the support, which has the effect of compressing, between the upper wall of the push button and the collar of the piece of material deformable, the product contained in the dose chamber, which passes between the tube and the tubular part of said part, escapes through the orifice (s) made radially in the tube and rises in the latter until the expulsion opening, after which the tubular part of said part, which has been stretched, resumes its initial shape, on the one hand by causing the push-button to go back up and by occluding the said radial orifice (s), thereby preventing the return of air or the return of the product contained in the tube; and on the other hand by causing the suction into the dose chamber of the product from the container, which passes through the peripheral orifice (s) of the upper wall of the support by pushing back the collar and passing between the peripheral lip and the internal face of the wall of the push button.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente quelques modes de réalisation non limitatifs.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents some non-limiting embodiments.

Si on se réfère à la figure 1 on peut voir qu'un dispositif selon l'invention comporte un bouton poussoir 1 adapté sur un support 2 sur lequel il peut coulisser verticalement, et qui est adapté sur un contenant, non représenté.If we refer to Figure 1 we can see that a device according to the invention comprises a push button 1 adapted on a support 2 on which it can slide vertically, and which is adapted on a container, not shown.

Le bouton poussoir 1 comporte une paroi extérieure tubulaire 10 délimitant, avec une paroi supérieure 11, un espace 12 d'un certain volume constituant une chambre dose.The push button 1 has a tubular outer wall 10 defining, with an upper wall 11, a space 12 of a certain volume constituting a dose chamber.

Le bouton poussoir 1 comporte également un tube 13 qui traverse l'espace 12, communiquant avec une ouverture d'expulsion 14, et qui est percé radialement d'un orifice 15 disposé à courte distance de son extrémité inférieure 16.The push button 1 also comprises a tube 13 which crosses the space 12, communicating with an expulsion opening 14, and which is pierced radially with an orifice 15 disposed a short distance from its lower end 16.

Le support 2 comprend une paroi supérieure 20 percée d'un orifice central 21 et d'orifices périphériques 22, dont un seul est visible sur la figure. Un tube plongeur 4 est d'autre part adapté sur le support 2.The support 2 comprises an upper wall 20 pierced with a central orifice 21 and peripheral orifices 22, only one of which is visible in the figure. A dip tube 4 is on the other hand adapted on the support 2.

Le dispositif comprend également une pièce 3 en matériau déformable élastique adaptée sur le support 2, entre celui-ci et le bouton poussoir 1.The device also comprises a part 3 of elastic deformable material adapted on the support 2, between the latter and the push button 1.

Comme on peut le voir sur la figure 3, la pièce déformable 3 comporte une partie centrale tubulaire 30 fermée à son extrémité inférieure par une paroi 32, et son extrémité supérieure est bordée par une collerette 33 comportant à sa face supérieure une gorge annulaire 34 bordée extérieurement par une lèvre périphérique 35.As can be seen in FIG. 3, the deformable part 3 comprises a tubular central part 30 closed at its lower end by a wall 32, and its upper end is bordered by a collar 33 having on its upper face an annular groove 34 bordered externally by a peripheral lip 35.

Si on se réfère également à la figure 2 on peut voir que l'orifice central 21 de la paroi supérieure 20 du support 2 est bordée d'une nervure 23 sur laquelle s'adapte la pièce 3, qui comporte à cet effet une rainure annulaire 36 entre la collerette 33 et la partie tubulaire 30.If one also refers to FIG. 2, it can be seen that the central orifice 21 of the upper wall 20 of the support 2 is bordered by a rib 23 on which the part 3 fits, which for this purpose has an annular groove 36 between the collar 33 and the tubular part 30.

Le tube 13 du bouton poussoir 1 est logé dans la partie tubulaire 30 de la pièce 3, son extrémité 16 au contact de la paroi 32, tandis que la collerette 33 est appliquée contre la paroi 20, obturant ainsi les orifices 22, et que la lèvre 35 est appliquée contre la face interne 17 de la paroi extérieure tubulaire 10 du bouton poussoir 1.The tube 13 of the push button 1 is housed in the tubular part 30 of the part 3, its end 16 in contact with the wall 32, while the flange 33 is applied against the wall 20, thus closing the orifices 22, and that the lip 35 is applied against the internal face 17 of the tubular external wall 10 of the push button 1.

L'expulsion d'une dose est réalisée de la manière suivante: une pression sur le bouton poussoir 1 provoque la descente du tube 13 qui déforme longitudinalement la partie tubulaire 30 de la pièce 3, le produit contenu dans la chambre-dose 12 est comprimé contre la collerette 33, ce qui a pour effet d'une part d'appliquer celle-ci contre la paroi supérieure 20 du support 2 et d'obturer ainsi les orifices 22, et d'autre part d'appliquer la lèvre périphérique 35 contre la face interne 17 de la paroi 10, ce qui renforce l'obturation en interdisant le désamorçage de la dose, tandis que le produit, repoussé entre le tube 13 et la partie tubulaire 30, s'échappe par l'orifice radial 15 du tube 13 et remonte dans ce dernier jusqu'à l'ouverture d'expulsion 14.The expulsion of a dose is carried out as follows: pressing the push button 1 causes the tube 13 to descend, which deforms longitudinally the tubular part 30 of the part 3, the product contained in the dose chamber 12 is compressed against the collar 33, which has the effect of, on the one hand, applying the latter against the upper wall 20 of the support 2 and thus to close the orifices 22, and on the other hand to apply the peripheral lip 35 against the internal face 17 of the wall 10, which reinforces the closure by preventing the defusing of the dose, while the product, repelled between the tube 13 and the tubular part 30, escapes through the radial orifice 15 of the tube 13 and rises in the latter until the expulsion opening 14.

Après l'expulsion de la dose et le relâchement de la pression sur le bouton poussoir 1, la partie tubulaire 30 de la pièce 3 reprend sa forme initiale et se plaque contre l'orifice 15, empêchant ainsi une reprise d'air et le retour du produit, et entraînant la remontée du bouton poussoir 1, ce qui crée dans la chambre dose 12 une dépression qui provoque l'aspiration du produit contenu dans le tube plongeur 4, lequel passe par les orifices périphériques 22 et emplit la chambre dose 12, la collerette 33 se soulevant sous la pression et la lèvre 35 se décollant de la face interne 17 de la paroi 10.After the expulsion of the dose and the release of the pressure on the push button 1, the tubular part 30 of the part 3 resumes its initial shape and is pressed against the orifice 15, thus preventing an air intake and the return of the product, and causing the push-button 1 to rise, which creates a vacuum in the dose chamber 12 which causes the suction of the product contained in the dip tube 4, which passes through the peripheral orifices 22 and fills the dose chamber 12, the flange 33 lifting under pressure and the lip 35 peeling off from the internal face 17 of the wall 10.

La paroi 10 du bouton poussoir 1 peut être avantageusement réalisée en un matériau transparent, pour permettre à l'utilisateur de voir la dose dans son intégralité, ce qui n'est pas réalisable avec les dispositifs doseurs connus.The wall 10 of the push button 1 can advantageously be made of a transparent material, to allow the user to see the dose in its entirety, which is not possible with known metering devices.

Sur la figure 1 on peut voir qu'une bague 24 est solidarisée extérieurement au support 2 en vue d'être introduite dans le contenant, un épaulement périphérique 25 limitant cette introduction, la paroi 10 du bouton poussoir 1 coulissant entre cette bague 24 et le support 2.In Figure 1 we can see that a ring 24 is secured externally to the support 2 to be introduced into the container, a peripheral shoulder 25 limiting this introduction, the wall 10 of the push button 1 sliding between this ring 24 and the support 2.

Le mode de réalisation représenté en figure 1 comprend un tube plongeur 4 et est à reprise d'air extérieur, et dans ce cas la bague 24 comporte, sous l'épaulement 25, un orifice 24' permettant l'entrée de l'air extérieur dans le contenant.The embodiment shown in Figure 1 comprises a dip tube 4 and is with external air intake, and in this case the ring 24 has, under the shoulder 25, an orifice 24 'allowing the entry of outside air in the container.

En référence aux figures 4a, 4b et 4c on peut voir que l'adaptation du dispositif selon l'invention sur un contenant, non représenté, peut être réalisée de différentes façons.With reference to FIGS. 4a, 4b and 4c, it can be seen that the adaptation of the device according to the invention to a container, not shown, can be carried out in different ways.

Sur la figure 4a l'épaulement 25 de la bague 24 prend appui sur le bord du contenant par l'intermédiaire d'un joint annulaire 26, la solidarisation étant réalisée au moyen d'une douille filetée 5.In FIG. 4a, the shoulder 25 of the ring 24 bears on the edge of the container by means of an annular seal 26, the connection being effected by means of a threaded sleeve 5.

Sur la figure 4b, l'épaulement 25 est prolongé vers le bas par une partie annulaire 27 munie d'un filetage 28.In FIG. 4b, the shoulder 25 is extended downwards by an annular part 27 provided with a thread 28.

Sur la figure 4c, la partie annulaire 27 comporte un cran 29 permettant son encliquetage sur le contenant.In FIG. 4c, the annular part 27 has a notch 29 allowing it to snap onto the container.

Si on se réfère maintenant à la figure 5 on peut voir que dans une variante du dispositif selon l'invention, destinée notamment au dosage d'un produit liquide, le support 2, la bague 24 et le contenant 6 sont d'une seule pièce, une fente 24' permettant la reprise d'air extérieur.Referring now to FIG. 5, it can be seen that in a variant of the device according to the invention, intended in particular for dosing a liquid product, the support 2, the ring 24 and the container 6 are in one piece , a slot 24 'allowing the intake of outside air.

Si on se réfère enfin à la figure 6 on peut voir un autre mode de réalisation du dispositif selon l'invention, sans reprise d'air extérieur, où un piston 60 coulisse dans le contenant 6.If we finally refer to FIG. 6, we can see another embodiment of the device according to the invention, without intake of outside air, where a piston 60 slides in the container 6.

Il va de soi que la présente invention ne saurait être limitée à la description qui précède de quelques-uns de ses modes de réalisation, susceptibles de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention.It goes without saying that the present invention cannot be limited to the foregoing description of some of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.
