Description
La présente invention concerne un dispositif de distribution d'un produit liquide à pâteux destiné à être mis en place à l'extrémité ouverte d'un contenant rigide, et constitué par un système doseur permettant la distribution d'une quantité prédéterminée de produit à délivrer.The present invention relates to a device for dispensing a liquid to pasty product intended to be put in place at the open end of a rigid container, and constituted by a metering system for dispensing a predetermined quantity of product to be delivered. .
Les premières pompes furent conçues pour des parfums initialement, et ont dérivé ensuite vers les pompes médicales. Ces pompes ont toujours mis en avant la précision de la dose, la protection du produit et la répétabilité.The first pumps were designed for perfumes initially, and then drifted to medical pumps. These pumps have always emphasized the precision of the dose, the protection of the product and the repeatability.
En conséquence de quoi, l'efficacité des pompes ayant primé sur le prix, le nombre de pièces d'une pompe standard oscille entre dix et quinze selon les modèles.As a result of which, the efficiency of the pumps having prevailed on the price, the number of parts of a standard pump oscillates between ten and fifteen according to the models.
L'utilisation de telles pompes a ensuite été adoptée pour la distribution de tous produits liquides à pâteux, que ce soit par exemple alimentaires, de produits cosmétiques, de produits d'hygiène, santé, beauté ou de produits solaires.The use of such pumps was then adopted for the distribution of any liquid to pasty products, whether for example food, cosmetics, hygiene products, health, beauty or solar products.
L'objectif était alors de simplifier la vie des utilisateurs en permettant d'obtenir une dose par un mouvement simple.The goal was then to simplify the life of the users by allowing to obtain a dose by a simple movement.
Mais à partir du moment où les pompes se sont positionnées sur des marchés à plus faible valeur ajoutée, tel que l'alimentaire ou la cosmétique, l'hygiène, santé et beauté, le prix des pompes a constitué un frein.But from the moment that the pumps were positioned in markets with lower added value, such as food or cosmetics, hygiene, health and beauty, the price of pumps has been a drag.
La plupart de ces nouveaux produits utilisant ces pompes sont des produits jetables, avec une durée d'utilisation réduite. De plus, leurs exigences en termes de précision de dose et de répétabilité sont plus réduites.Most of these new products using these pumps are disposable products with reduced service life. In addition, their requirements in terms of dose accuracy and repeatability are reduced.
Il existe actuellement sur le marché un certain nombre de produits comportant des pompes, mais beaucoup de ces pompes représentent une réponse exagérée à l'attente du consommateur, du point de vue capacités techniques et coûts.There are currently a number of pumped products on the market, but many of these pumps represent an exaggerated response to consumer expectations from the point of view of technical capabilities and costs.
Cette problématique de coût apparaît depuis peu avec la démocratisation des produits, initialement haut de gamme, à adapter à la grande distribution.This problem of cost appears recently with the democratization of products, initially high-end, to adapt to large-scale distribution.
C'est ainsi qu'a déjà été recherchée la réalisation d'un système de distribution par pompe présentant peu de pièces, en tout cas le moins possible, de manière à le rendre économique, et que de nombreux brevets ont été déposés dans ce domaine, décrivant des pompes comportant par exemple cinq pièces : une pièce par valve + base + bouton poussoir + chambre déformable.Thus, it has already been sought the realization of a pump dispensing system with few parts, at least as little as possible, so as to make it economical, and that many patents have been filed in this field. , describing pumps comprising for example five parts: one piece per valve + base + push button + deformable chamber.
Mais si la première vague de pompes simplifiées avait une volonté de réduire les coûts de production, la deuxième a recherché à augmenter la qualité.But if the first wave of simplified pumps had a desire to reduce production costs, the second sought to increase quality.
C'est ainsi que le brevet
- un élément de base destiné à être mis en place sur le contenant par son extrémité inférieure,
- un bouton poussoir muni d'un bec de distribution monté télescopiquement à la partie supérieure de l'élément de base et susceptible d'agir en pompage par rapport à ce dernier, à l'encontre d'un organe de rappel constitué par
- un soufflet élastiquement déformable assurant la liaison étanche entre d'une part une chambre interne de l'élément de base, ouverte vers le contenant pour permettre le passage du produit au travers d'une ouverture, et d'autre part, à son extrémité supérieure, une chambre interne du bouton poussoir dans laquelle débouche un trou du bec de distribution.
- a base element intended to be placed on the container by its lower end,
- a push button provided with a dispensing spout telescopically mounted on the upper part of the base element and capable of acting in pumping with respect to the latter, against a return member constituted by
- an elastically deformable bellows providing the sealed connection between an internal chamber of the base element, open towards the container to allow the passage of the product through an opening, and on the other hand, at its upper end. , an internal chamber of the push button in which opens a hole of the dispensing spout.
Cependant, ce système distributeur précité présente un inconvénient majeur.However, this aforementioned dispensing system has a major disadvantage.
En effet, lors d'un appui accidentel sur le contenant sur lequel ce distributeur est positionné, du produit peut être distribué inopinément, du fait que les différentes valves et soupapes d'ouverture-fermeture situées dans le circuit fonctionnant dans le même sens ne permettent pas d'empêcher la sortie du produit.Indeed, during an accidental support on the container on which this distributor is positioned, the product can be dispensed unexpectedly, because the different valves and opening-closing valves located in the circuit operating in the same direction do not prevent the exit of the product.
Il peut advenir également que le contenant fermé par le distributeur soit soumis à une dépression comme dans le cas d'un voyage en avion ou en cas de changement de température. Dans ces cas là, les différentes valves et soupapes d'ouverture-fermeture situés dans le circuit fonctionnant dans le même sens ne permettent pas d'empêcher la sortie du produit, occasionnant par la même une pollution de l'environnement.It may also happen that the container closed by the distributor is subjected to a depression as in the case of a trip by plane or in case of change of temperature. In these cases, the various valves and opening-closing valves located in the circuit operating in the same direction do not prevent the exit of the product, thereby causing environmental pollution.
La présente invention a pour but de remédier à cet inconvénient et concerne à cet effet un dispositif de distribution d'un produit liquide à pâteux destiné à être mis en place à l'extrémité ouverte d'un contenant rigide et constitué par une pompe manuelle de dosage permettant la délivrance d'une quantité prédéterminée de produit à distribuer, comprenant :
- un élément de base destiné à être mis en place sur le contenant par son extrémité inférieure, par un moyen d'accroche ou d'adhésion tel que clipsage ou vissage
- un bouton poussoir muni d'un bec de distribution monté télescopiquement à la partie supérieure de l'élément de base et susceptible d'agir en pompage par rapport à ce dernier, à l'encontre d'un organe de rappel constitué par
- un soufflet élastiquement déformable assurant la liaison étanche entre d'une part une chambre interne de l'élément de base, ouverte vers le contenant pour permettre le passage du produit au travers d'une ouverture, et d'autre part, à son extrémité supérieure, une chambre interne du bouton poussoir dans laquelle débouche un trou du bec de distribution, associé à des moyens d'ouverture-fermeture, réalisés à l'extrémité supérieure dudit soufflet,
- une première collerette périphérique interne réalisée à l'extrémité supérieure du soufflet, se logeant dans une gorge annulaire interne du bouton poussoir formant chambre, et en appui sur une de ses parois interne qu'elle enserre élastiquement selon une force prédéterminée, de façon à assurer l'étanchéité ou à être soulevée radialement sous une certaine pression du produit lors de la compression du soufflet et du produit qu'il contient et permettre ainsi son transfert dans la gorge annulaire, ladite première collerette étant associée à
- une seconde collerette du soufflet, concentrique à la première, se logeant dans la même gorge du bouton poussoir, mais en appui sur la paroi externe de celle-ci dans laquelle débouche l'orifice du bec de distribution, ladite seconde collerette étant d'une hauteur telle à ne pas obturer ledit orifice, l'ouverture ou la fermeture de ce dernier s'effectuant par l'intermédiaire d'une languette de verrouillage concave, issue de la collerette, de hauteur et de largeur au moins telles à obturer l'orifice par plaquage, ou à le libérer au cours d'une action en rotation, dans un sens ou dans l'autre, sur ledit bouton poussoir, par rapport à l'élément de base, et conséquemment au soufflet, et à sa languette, demeurant fixes.
- a base element intended to be placed on the container by its lower end, by means of attachment or adhesion such as clipping or screwing
- a push button provided with a dispensing spout telescopically mounted on the upper part of the base element and capable of acting in pumping with respect to the latter, against a return member constituted by
- an elastically deformable bellows providing the sealed connection between an internal chamber of the base element, open towards the container to allow the passage of the product through an opening, and on the other hand, at its upper end. an internal chamber of the push button into which a hole of the dispensing spout opens, associated with opening-closing means, made at the upper end of said bellows,
- a first internal peripheral flange formed at the upper end of the bellows, housed in an annular groove inside the pushbutton forming a chamber, and resting on one of its inner walls which it elastically encloses according to a predetermined force, so as to ensure the seal or to be lifted radially under a certain pressure of the product during compression of the bellows and the product it contains and thus allow its transfer into the annular groove, said first collar being associated with
- a second flange of the bellows, concentric with the first, housed in the same groove of the push button, but resting on the outer wall thereof in which opens the orifice of the dispensing spout, said second collar being of a height such as not to close said orifice, the opening or closing of the latter being effected by means of a locking tab concave, resulting from the collar, of height and width at least such to close the orifice by plating, or to release it during a rotating action, in one direction or the other, on said push button, relative to the base element, and consequently the bellows, and its tongue, remaining fixed.
De cette manière, tout appui accidentel, selon le but recherché, sur le bouton poussoir en position de fermeture interdira la sortie du produit par opposition de la languette de verrouillage, dont le plaquage contre l'orifice du bec n'en sera qu'accentué par la pression du produit. C'est la languette de verrouillage qui fera opposition à cette sortie.In this way, any accidental support, depending on the purpose, on the push button in the closed position will prohibit the release of the product as opposed to the locking tongue, the plating against the mouth of the nozzle will be accentuated by the pressure of the product. This is the locking tab that will oppose this exit.
L'invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.

Les moyens d'indexation du soufflet sont constitués par au moins une dent radiale 22, réalisée sur le fond de la chambre interne 12 de l'élément de base 6, destinée à coopérer avec une encoche correspondante 23 de la base 21 du soufflet 11.The indexing means of the bellows consist of at least one
Selon le présent exemple de réalisation, la base 21 du soufflet 11 comporte trois encoches d'indexation et d'anti-rotation radiales 23 formant entre elles des angles au centre de 120°, 125° et 115°, s'emboîtant sur des dents correspondantes 22 de la chambre interne 12.According to the present embodiment, the
Un autre moyen de réalisation de l'indexation est de positionner un décroché 42 dans le tube 38 de la base 6, de manière à pouvoir assembler le soufflet 11 en indexant la position de la lamelle 20 du soufflet 11 par rapport à la position du décroché 42 de la base 6. Les encoches 22 et 23 seraient cependant conservées pour assurer une anti rotation du soufflet 11 par rapport à la base 6, mais pourraient alors être d'angles identiques.Another embodiment of the indexing is to position a
Selon une autre caractéristique de l'invention, le bouton poussoir 8 comporte des moyens d'indexation par rapport à l'élément de base 6, et conséquemment du soufflet 11 et de sa languette de verrouillage 20 du bec 9, qui sont fixes par rapport à l'élément de base 6.According to another characteristic of the invention, the
Ces moyens d'indexation sont constitués par au moins une nervure axiale 24 réalisée sur la paroi interne du bouton poussoir 8 destinée à coopérer avec une rainure correspondante 25 d'une jupe interne 26 de l'élément de base 6 délimitant sa chambre interne 12 d'une part, et un logement périphérique 27 avec la paroi externe 28 dudit élément de base 6 d'autre part, lequel logement 27 est destiné à recevoir la paroi du bouton poussoir 8 et permettre à la fois son coulissement axial et sa rotation à l'intérieur de celui-ci.These indexing means are constituted by at least one
Ceci permet un déplacement du bouton poussoir 8 dans l'élément de base 6 de manière bien rectiligne, et limite ainsi l'effet de descente ou de remontée de guingois, du fait du guidage obtenu.This allows a displacement of the
Selon le présent exemple de réalisation, la jupe 26 de l'élément de base 6 comporte trois rainures 25 destinées à coopérer avec trois nervures axiales correspondantes 24 du bouton poussoir 8, pour constituer leurs moyens d'indexation, selon des angles de 120° chacun.According to the present embodiment, the
Selon une autre caractéristique de l'invention, la hauteur des rainures 25 de la jupe 26 est inférieure d'une part à la hauteur de celle-ci, du fait de décrochements sectoriels 29 qui y sont réalisés, du même côté de chaque rainure 25, et d'autre part inférieure à la hauteur des nervures 24 du bouton poussoir 8, de manière à autoriser son coulissement axial selon une certaine course, dans une position d'ouverture, et donc de pompage du produit, ou son blocage en fermeture en position haute, après rotation dans le sens des décrochements 29, mettant l'extrémité basse des nervures 24 dudit bouton poussoir 8 en butée contre les décrochements 29 de la jupe 26.According to another characteristic of the invention, the height of the
L'angle au centre des décrochements sectoriels 29 est fonction de la course rotative souhaitée.The angle at the center of the
Selon une autre caractéristique de l'invention, l'extrémité périphérique haute de la jupe interne 26 de l'élément de base 6 et l'extrémité périphérique basse de la paroi du bouton poussoir 8 comportent des moyens d'encliquetage 30,31 disposés respectivement à l'extérieur de la jupe 26 et à l'intérieur du bouton poussoir 8, de manière à autoriser une course axiale de celui-ci ainsi que sa rotation en position haute, tout en assurant sa retenue axiale sur l'élément de base 6.According to another characteristic of the invention, the upper peripheral end of the
De cette manière, la partie d'accrochage située sur le bouton poussoir ne gêne en rien la réalisation et le démoulage de la pièce vers le bas. Du côté de l'élément de base, cela permet de cacher la partie d'encliquetage et de pouvoir modifier la rigidité du clipsage en travaillant sur les formes des parties clipsantes discontinues.In this way, the attachment portion located on the push button does not interfere with the production and demolding of the workpiece downwards. On the side of the base member, this allows to hide the snap portion and to be able to modify the rigidity of the clipping by working on the shapes of the discontinuous clipping parts.
Selon un autre mode de réalisation en
Selon une autre caractéristique de l'invention, la première collerette périphérique interne 16 du soufflet 11, en appui sur la paroi interne 17 de la gorge 14 du bouton poussoir 8 dans laquelle il est logé, forme une géométrie convexe par rapport à celle-ci, puis concave avant que le produit 2 ne sorte entre ladite collerette 16 et la paroi interne 17 de la gorge 14 du bouton poussoir 8, avant de s'échapper par son bec 9, puis qui redevient convexe lors de la cessation de la pression positive dans le soufflet 11. (Voir
En effet, une géométrie convexe de la collerette 16 permet de pouvoir assurer un gonflement périphérique de celle-ci avant qu'elle ne s'ouvre, et que du produit ne passe entre la paroi de ladite gorge et ladite collerette.In fact, a convex geometry of the
Ce gonflement limite le volume situé entre la collerette et le canal de distribution de la collerette 16 et l'orifice 15 du bec de distribution 9.This swelling limits the volume located between the flange and the dispensing channel of the
Le produit est ensuite distribué normalement. Lorsque la pression exercée cesse ainsi que la délivrance du produit 2, le soufflet 11 est ramené en position initiale par son effet de mémoire élastique. La dépression occasionnée dans le soufflet 11 du fait de son retour en position initiale ramène la collerette 16 d'une position concave à une position convexe.The product is then distributed normally. When the pressure exerted ceases and the delivery of the
Cette variation de cambrure occasionne une variation du volume présent dans l'espace compris entre la collerette 16 et l'orifice 15 de distribution, et par là même une réaspiration du produit situé dans cet orifice, évitant la création d'un résidu à ce niveau, donnant une impression de salissure.This camber variation causes a variation of the volume present in the space between the
Selon une autre caractéristique de l'invention comme présenté sur une autre version, le dispositif comporte des moyens de reprise d'air constitués par au moins un évent constitué par :
- au moins une gorge axiale 32 réalisées sur une partie du filetage 33 de l'élément de
base 6, devant coopérer avecun filetage 34 du contenant 4, - au moins une
gorge radiale 35 en communication avecla gorge axiale 32 est réalisée sous la paroi 36 de la chambre 12 de l'élément debase 6, - des passages axiaux 37 réalisés selon des génératrices d'une cheminée axiale 38 de l'élément de
base 6 plongeant dans le contenant 4, ladite cheminée 38 comportant, dans sa partie haute, adjacente à la paroi de la chambre 12, troisbossages 39 disposés périphériquement, définissant entre eux lesditspassages 37, - un joint d'étanchéité déformable 40 interposé entre la
base du col 3 du contenant 4 et le dessous 36 de la chambre 12 de l'élément debase 6, comportant lagorge radiale 35, lequel joint 40 à un diamètre intérieur sensiblement égal à celui dans lequel s'inscrivent les bossages 39 en laissant libres lespassages 37 et un diamètre extérieur tel à ne pas occulter lagorge axiale 32 du filetage 33 de l'élément debase 6.
- at least one
axial groove 32 made on a portion of thethread 33 of thebase element 6, to cooperate with athread 34 of thecontainer 4, - at least one
radial groove 35 in communication with theaxial groove 32 is formed under thewall 36 of thechamber 12 of thebase element 6, -
axial passages 37 made in generatrices of anaxial chimney 38 of thebase element 6 immersed in thecontainer 4, saidchimney 38 comprising, in its upper part, adjacent to the wall of thechamber 12, threebosses 39 arranged peripherally, defining between them saidpassages 37, - a
deformable seal 40 interposed between the base of theneck 3 of thecontainer 4 and the bottom 36 of thechamber 12 of thebase member 6, comprising theradial groove 35, which seal 40 has an inside diameter substantially equal to that in which thebosses 39 are inserted, leaving thepassages 37 free and an outside diameter such as not to obscure theaxial groove 32 of thethread 33 of thebase element 6.
De cette manière, la reprise d'air s'effectue à partir de l'air ambiant extérieur en passant sans discontinuité par la gorge axiale 32, puis la gorge radiale 35, puis les passages périphériques 39, vers l'intérieur du contenant 4.In this way, the return of air is effected from the outside ambient air passing without discontinuity through the
A noter qu'un tel évent est suffisamment grand pour laisser passer de l'air dans un flux quasi statique, mais trop fin pour laisser passer du liquide, même soumis à une forte pression.Note that such a vent is large enough to let air in an almost static flow, but too fine to let liquid, even under strong pressure.
Dans l'art antérieur, il était connu de réaliser une reprise d'air à travers un ensemble de trous situés à la périphérie et surmontés d'une collerette qui permet de laisser entrer l'air tout en empêchant de laisser sortir le produit.In the prior art, it was known to make a return air through a set of holes located at the periphery and surmounted by a collar that allows air to enter while preventing the product from leaving.
L'effet néfaste d'utiliser une lèvre souple est son manque d'efficacité pour empêcher que des produits liquides ne fuient par cet endroit.The detrimental effect of using a soft lip is its lack of efficiency to prevent liquid products from leaking through this place.
De plus, la fragilité de ce type de lèvre pouvant être détériorée par un coup lors du transport ou de l'assemblage par exemple compromet une bonne étanchéité. Enfin, dans le cas de hausse de la pression dans le contenant, due par exemple à une exposition à une source de chaleur, à partir du moment où le produit ne force pas le passage dans la pompe, la pression peut forcer le produit à passer à travers le trou de reprise d'air et à s'infiltrer à la périphérie de la lèvre d'étanchéité précitée.In addition, the fragility of this type of lip can be damaged by a blow during transportation or assembly for example compromises a good seal. Finally, in the case of increased pressure in the container, for example due to exposure to a heat source, from the moment when the product does not force the passage through the pump, the pressure can force the product to pass. through the air intake hole and to infiltrate the periphery of the aforementioned sealing lip.
Avantageusement, les différentes pièces du système sont réalisées en matières plastiques.Advantageously, the various parts of the system are made of plastics.
Avantageusement, le soufflet est réalisé en une matière plastique, de préférence élastiquement déformable.Advantageously, the bellows is made of a plastic material, preferably elastically deformable.
Avantageusement, la matière constitutive du soufflet présente l'élasticité du caoutchouc et est en même temps en mesure de fournir, entre les deux éléments de boîtier, les forces de rappel nécessaires pour le pompage. C'est ainsi que le choix a été orienté vers une matière plastique suffisamment souple pour assurer une bonne étanchéité au niveau des collerettes, suffisamment nerveuse pour assurer un retour en position initiale et assurer une dépression, et suffisamment résistante au fluage pour permettre de conserver les serrages initiaux ainsi que conserver une répétabilité de course de compression et donc de dose.Advantageously, the constituent material of the bellows has the elasticity of the rubber and is at the same time able to provide, between the two housing elements, the restoring forces necessary for pumping. Thus, the choice was directed to a plastic material sufficiently flexible to ensure a good seal at the collars, sufficiently nervous to ensure a return to the initial position and ensure a vacuum, and sufficiently resistant to creep to allow to retain the initial tightening and maintain a repeatability of compression stroke and therefore dose.
Préférentiellement, le soufflet est réalisé en polyuréthane injectable.Preferably, the bellows is made of injectable polyurethane.
Egalement, pourraient être utilisés du SANTOPRENE (Polypropylène modifié Caoutchouc Ethylène-Propylène Diène), ou des HYTREL (Thermoplastique Elastomère Ether-Ester, DRYFLEX (Thermoplastique Styrénique Styrène-Ethylène-Butadiène-Styrène) matières qui n'existaient pas il y a une vingtaine d'années, ainsi que vers certaines références de polyéthylènes réalisés ou modifiés pour garantir une nervosité et une tenue acceptable au fluage.Also, could be used SANTOPRENE (Polypropylene modified Ethylene-Propylene Diene Rubber), or HYTREL (Thermoplastic Elastomer Ether-Ester, DRYFLEX (Styrene Thermoplastic Styrene-Ethylene-Butadiene-Styrene) materials that did not exist there are twenty of years, as well as towards certain references of polyethylenes made or modified to guarantee a nervousness and an acceptable resistance to creep.
Les noms sont les noms commerciaux, entre parenthèses les noms chimiques.The names are the trade names, in parentheses the chemical names.
Ces matières présentent toutes les caractéristiques énoncées plus haut.These materials have all the characteristics listed above.
Selon une autre caractéristique de l'invention, un ressort (non représenté) métallique ou non, est disposé autour du soufflet 11.According to another characteristic of the invention, a spring (not shown) metal or not, is arranged around the
En effet, dans le cas de la distribution de produits très visqueux où la résilience du soufflet ne suffit pas pour assurer son retour en position initiale suffisamment rapidement et n'assure pas une dépression répétable menant à des doses identiques, un ressort complémentaire peut s'avérer utile pour aider ce retour en position initiale, tout en conservant une élasticité suffisante au niveau des collerettes.Indeed, in the case of the dispensing of highly viscous products where the resilience of the bellows is not sufficient to ensure its return to the initial position sufficiently quickly and does not ensure a repeatable depression leading to identical doses, a complementary spring can s' prove useful to help this return to the initial position, while maintaining sufficient elasticity at the collars.
