Description

La présente invention concerne l'industrie des petites pompes manuelles couramment utilisées pour la distribution ou la pulvérisation de substances liquides ou semi-liquides, notamment de produits ménagers, d'entretien ou cosmétiques, ou encore de produits pharmaceutiques.The present invention relates to the industry of small manual pumps commonly used for the distribution or spraying of liquid or semi-liquid substances, in particular household, maintenance or cosmetic products, or even pharmaceutical products.

Les pompes du commerce doivent être maintenues généralement verticales, avec une certaine liberté d'inclinaison,pour fonctionner correctement.Commercial pumps must be kept generally vertical, with some freedom of tilt, to function properly.

On a conçu également des conditionnements pouvant être utilisés indifféremment en position verticale normale ou retournée, plus particulièrement en conditionnement aérosol .We have also designed packaging that can be used indifferently in normal or inverted vertical position, more particularly in aerosol packaging.

Ces dispositifs connus font généralement appel à un ou plusieurs clapets gravimétriques à billes qui conditionnent l'admission du liquide à la pompe, ou à la valve,par un tube plongeur débouchant au fond du récipient ou au niveau de l'attache de l'autre extrémité du tube plongeur, en bout de la pompe ou de la valve.These known devices generally use one or more gravimetric ball valves which condition the admission of the liquid to the pump, or to the valve, by a dip tube opening out at the bottom of the container or at the level of the attachment of the other. end of the dip tube, at the end of the pump or valve.

Cependant, le fonctionnement de ces dispositifs connus est incertain pour des inclinaisons importantes, voisines à ± 5% de l'horizontale, car la ou les billes n'occupent pas alors une position opérationnelle stable dans leur logement.However, the operation of these known devices is uncertain for large inclinations, close to ± 5% of the horizontal, since the ball or balls do not then occupy a stable operational position in their housing.

L'invention a pour but de pallier les inconvénients précités des dispositifs classiques et de permettre de réaliser des pompes fonctionnant pratiquement en toutes positions.The invention aims to overcome the aforementioned drawbacks of conventional devices and to make it possible to produce pumps operating in practically any position.

L'invention a pour objet une pompe à commande manuelle utilisable en toutes positions, comprenant un corps de pompe solidarisable du col d'un récipient renfermant la substance à distribuer, prolongé à l'intérieur du récipient par un tube axial plongeant jusqu'au fond du récipient et communiquant avec l'intérieur du corps de pompe, l'élément mobile de la pompe sollicité par un ressort de rappel en éloignement de l'élément fixe de la pompe,étant solidaire d'un poussoir manuel axial comportant une buse de distribution de la substance pompée, en communication avec l'intérieur du corps de pompe, - pompe caractérisée en ce qu'elle comporte un premier clapet antiretour non gravimétrique d'admission, intercalé entre le tube plongeur, et le corps de pompe, un clapet gravimétrique d'interdiction d'admission en position retournée intercalé entre le tube plongeur et le premier clapet, un second clapet antiretour non gravimétrique, d'admission par une dérivation entre le premier clapet et le clapet gravimétrique, s'ouvrant en réponse à une dépression aval et un clapet antiretour de refoulement intercalé entre l'intérieur du corps de pompe et la buse.The subject of the invention is a manually operated pump usable in any position, comprising a pump body which can be secured to the neck of a container. containing the substance to be dispensed, extended inside the container by an axial tube plunging to the bottom of the container and communicating with the interior of the pump body, the movable element of the pump urged by a return spring away the fixed element of the pump, being integral with an axial manual pusher comprising a nozzle for distributing the pumped substance, in communication with the interior of the pump body, - pump characterized in that it comprises a first valve non-gravimetric intake check valve, interposed between the dip tube, and the pump body, a gravimetric intake prohibition valve in the inverted position inserted between the dip tube and the first valve, a second non-gravimetric check valve, inlet bypass between the first valve and the gravimetric valve, opening in response to a downstream vacuum and a non-return valve interposed between the interior of the pump body and the bu se.

Le corps de pompe peut comprendre un socle solidarisable du col du récipient, prolongé axialement, vers l'intérieur du récipient par un téton tubulaire de fixation du tube plongeur, et vers l'intérieur du corps de pompe par un piston fixe annulaire coulissant à l'intérieur d'un cylindre mobile solidaire du poussoir.The pump body may comprise a base which can be secured to the neck of the container, extended axially towards the inside of the container by a tubular stud for fixing the dip tube, and towards the inside of the pump body by a fixed annular piston sliding at inside of a movable cylinder secured to the pusher.

Le cylindre peut coulisser librement sur une course limitée à l'intérieur d'un prolongement cylindrique issu du socle.The cylinder can slide freely over a limited stroke inside a cylindrical extension from the base.

Le socle peut être réalisé simplement en forme de plateau annulaire en appui étanche contre la tranche du col du récipient.The base can be produced simply in the form of an annular plate in leaktight support against the edge of the neck of the container.

Le socle peut présenter un logement tubulaire axial dans lequel est insérée la base d'un piston tubulaire souple, borgne, dont le fond est découpé pour former une languette en appui élastique sur un épaulement annulaire du fond du logement avec lequel elle constitue le premier clapet antiretour non gravimétrique.The base may have an axial tubular housing in which is inserted the base of a flexible, blind tubular piston, the bottom of which is cut to form a tab in elastic support on an annular shoulder of the bottom of the housing with which it constitutes the first non-gravimetric non-return valve.

Dans un mode de réalisation,le piston présente une jupe annulaire élastique en saillie sur sa paroi latérale, qui coopère avec un bourrelet annulaire du socle pour former un troisième clapet antiretour non gravimétrique, d'aération de l'intérieur du récipient par un passage latéral entre le piston et le socle, débouchant à l'intérieur du récipient.In one embodiment, the piston has an elastic annular skirt projecting from its side wall, which cooperates with an annular bead of the base to form a third non-gravimetric non-return valve, ventilating the interior of the container by a lateral passage between the piston and the base, opening inside the container.

Dans un mode de réalisation pratique, le clapet gravimétrique d'interdiction d'admission en position retournée est constitué par une bille maintenue dans une cage à-bille dont une moitié est constituée par l'extrémité d'un embout tubulaire,inséré dans le téton tubulaire de fixation du tube plongeurprésen- tant un épaulement de repos de la bille avec un passage en contournement, et dont l'autre moitié est constituée par la base d'un chapeau tronconique ouvert débouchant axialement en dessous du premier clapet.In a practical embodiment, the gravimetric valve for prohibiting admission in the inverted position consists of a ball held in a ball cage, one half of which is formed by the end of a tubular end piece, inserted in the stud. tubular for fixing the dip tube having a shoulder for resting the ball with a bypass passage, and the other half of which is constituted by the base of an open frustoconical cap opening axially below the first valve.

Il est alors avantageux que le téton tubulaire soit percé d'une lumière radiale de dérivation faisant communiquer l'intérieur du récipient avec l'intérieur du téton autour du chapeau tronconique,dont l'extrémité de la paroi extérieure vient en appui élastique contre un épaulement annulaire du téton, pour constituer le second clapet antiretour non gravimétrique d'admission en dérivation du tube plongeur.It is then advantageous for the tubular stud to be pierced with a radial bypass lumen communicating the interior of the container with the interior of the stud around the frustoconical cap, the end of the outer wall of which bears resiliently against a shoulder. annular of the nipple, to constitute the second non-gravimetric non-return valve for intake in derivation of the dip tube.

Il est commode que le passage latéral d'aération débouche dans la lumière radiale de dérivation percée dans le téton du socle.It is convenient for the lateral ventilation passage to open into the radial bypass lumen pierced in the nipple of the base.

Dans un autre mode de réalisation avantageux, le clapet antiretour est constitué par une rondelle élastique bi- conique en forme de doigt de gant retournée dont la partie conique retournée interne vient porter élastiquement contre une tige axiale cylindrique issue du fond du cylindre,pour former un clapet non gravimétrique de refoulement entre l'intérieur du corps de pompe et un passage latéral à la tige communiquant avec la buse de distribution.In another advantageous embodiment, the check valve return consists of a bi-conical elastic washer in the form of an inverted glove finger, the internal inverted conical part of which bears elastically against a cylindrical axial rod coming from the bottom of the cylinder, to form a non-gravimetric delivery valve between the interior of the pump body and a lateral passage to the rod communicating with the dispensing nozzle.

L'invention sera mieux comprise à la lecture de la description détaillée qui va suivre et à l'examen des dessins annexés qui représentent, à titre d'exemple non limitatif un mode de réalisation de l'invention.The invention will be better understood on reading the detailed description which follows and on examining the appended drawings which represent, by way of non-limiting example, an embodiment of the invention.

La pompe représentée sur ces figures comprend essentiellement un corps de pompe l,assujetti par l'intermédiaire d'un joint annulaire d'étanchéité 11 sur le col 13 d'un récipient 14.The pump shown in these figures essentially comprises a pump body 1, secured by means of an annular seal 11 on the neck 13 of a container 14.

Dans le mode de réalisation représenté, le corps est maintenu sur le col du récipient par une capsule en métal malléable 35 qui est sertie en dessous de la carnette du col du flacon. En variante, elle pourrait aussi bien être vissée sur un col à vis.In the embodiment shown, the body is held on the neck of the container by a malleable metal capsule 35 which is crimped below the the neck of the bottle. Alternatively, it could as well be screwed onto a screw neck.

Ce corps de pompe 1 comprend un socle 12,prolongé axialement vers l'intérieur du récipient par un téton tubulaire 16,dans lequel est inséré un embout tubulaire 8 à une extrémité duquel est inséré un tube plongeur 3, débouchant au fond du récipient 14 qui renferme la substance 15 à distribuer.This pump body 1 comprises a base 12, extended axially towards the inside of the container by a tubular stud 16, into which is inserted a tubular end piece 8 at one end of which is inserted a dip tube 3, opening at the bottom of the container 14 which contains substance 15 to distribute.

L'autre extrémité de l'embout tubulaire 8 constitue la partie inférieure d'une cage à bille et présente un épaulement annulaire 28 sur lequel peut venir reposer une bille 26, cependant qu'une fente radiale 29 constitue un passage en détournement autour de la bille 26 pour permettre à la substance 15 de contourner la bille. La partie supérieure de la cage à bille est constituée par un chapeau tronconique 30, en matériau élastique, dont l'extrémité de la paroi extérieure vient en appui élastique contre un épaulement annulaire 31 du téton 16,pour constituer un clapet antiretour non gravimétrique d'admission de la substance 15,en dérivation du tube plongeur 3 par une lumière radiale 10 de dérivation percée dans le téton 16 du socle 12, lorsque le récipient est retourné.The other end of the tubular end piece 8 constitutes the lower part of a ball cage and has an annular shoulder 28 on which a ball 26 can come to rest, while a radial slot 29 constitutes a diversion passage around the ball 26 to allow substance 15 to bypass the ball. The upper part of the ball cage is constituted by a frustoconical cap 30, made of elastic material, the end of the outer wall of which bears in elastic support against an annular shoulder 31 of the stud 16, to form a non-gravimetric check valve of inlet of the substance 15, bypassing the dip tube 3 by a radial lumen 10 bypass pierced in the stud 16 of the base 12, when the container is inverted.

Le socle 12 est prolongé axialement à l'opposé du téton 16,portant le tube plongeur et la cage à bille, par un logement tubulaire axial 19 dans lequel est insérée la base du piston tubulaire souple et borgne 4 dont le fond est découpé pour former une languette 21, qui vient en appui élastique sur un épaulement annulaire 22 du fond du logement 19 avec lequel elle constitue un clapet antiretour non gravimétrique,qui autorise l'entrée de la substance à distribuer en provenance du tube plongeur en position normale,et en provenance du canal de dérivation 10 en position retournée,sous contrôle de la lèvre du chapeau tronconique 30,qui s'incurve élastiquement de son siège constitué par l'épaulement 31 sous l'effet de l'aspiration.The base 12 is extended axially opposite the stud 16, carrying the plunger tube and the ball cage, by an axial tubular housing 19 in which is inserted the base of the flexible and blind tubular piston 4 whose bottom is cut to form a tongue 21, which comes into resilient abutment on an annular shoulder 22 of the bottom of the housing 19 with which it constitutes a non-gravimetric non-return valve, which allows the entry of the substance to be dispensed from the dip tube in the normal position, and coming from the bypass channel 10 in the inverted position, under control of the lip of the frustoconical cap 30, which curves elastically from its seat formed by the shoulder 31 under the effect of the suction.

Par contre, lors de la compression (figure 3), la languette 21 porte en appui étanche contre l'épaulement 22 pour interdire tout refoulement de ce côté de la substance préalablement aspirée dans le corps de pompe.On the other hand, during compression (FIG. 3), the tongue 21 bears in leaktight support against the shoulder 22 to prevent any backflow on this side of the substance previously sucked into the pump body.

Le piston 4 présente également une jupe annulaire 23,en saillie sur sa paroi latérale,qui porte élastiquement sur un bourrelet annulaire 24 du socle 12 pour former un clapet antiretour non gravimétrique, qui permet l'aération de l'intérieur du récipient lorsqu'une dépression s'y manifeste,par entrée d'air extérieur dans un passage formé par une rainure radiale 25 creusée dans le socle 12 qui débouche, d'une part dans l'espace entre la jupe 23 du piston et le bourrelet 24, et d'autre part dans le conduit radial 10 du téton tubulaire portant le tube plongeur.The piston 4 also has an annular skirt 23, projecting from its side wall, which bears elastically on an annular bead 24 of the base 12 to form a non-gravimetric non-return valve, which allows ventilation of the interior of the container when a depression is manifested therein, by entry of outside air into a passage formed by a radial groove 25 hollowed out in the base 12 which opens, on the one hand into the space between the skirt 23 of the piston and the bead 24, and d on the other hand in the radial duct 10 of the tubular stud carrying the dip tube.

Le piston 4, fixe, coulisse à l'intérieur d'un cylindre.2 mobile,solidaire d'un poussoir manuel 5 à l'intérieur d'un prolongement cylindrique 18 issu du socle 12.The fixed piston 4 slides inside a movable cylinder. 2 secured to a manual pusher 5 inside a cylindrical extension 18 coming from the base 12.

La course du cylindre 2 est limitée par un épaulement annulaire 36 de l'extrémité du prolongement cylindrique l8,contre lequel vient porter un épaulement extérieur 37 du cylindre 2.The stroke of the cylinder 2 is limited by an annular shoulder 36 of the end of the cylindrical extension 18, against which comes an outer shoulder 37 of the cylinder 2.

Dans le mode de réalisation représenté, le socle 2 est inséré élastiquement dans le prolongement cylindrique 18 dans lequel il vient s'encliqueter,et l'assemblage est affermi par une cheminée 38 prolongeant la capsule 35.In the embodiment shown, the base 2 is inserted elastically in the cylindrical extension 18 into which it snaps, and the assembly is strengthened by a chimney 38 extending the capsule 35.

Le fond du cylindre 2 est prolongé par un embout tubulaire 39 qui vient s'insérer de façon étanche à l'intérieur du poussoir 5,en communication avec un conduit radial 40 débouchant dans une buse de pulvérisation classique 6,à effet tourbillonnaire dans le mode de réalisation représenté.The bottom of the cylinder 2 is extended by a tubular end piece 39 which fits tightly inside the pusher 5, in communication with a radial duct 40 opening into a conventional spray nozzle 6, with a vortex effect in the mode shown.

En variante, la buse peut être remplacée par un simple ajutage.Alternatively, the nozzle can be replaced by a simple nozzle.

L'embout tubulaire 39 communique avec l'intérieur du cylindre 2 par un conduit désaxé 34,parallèle à une tige axiale 33 faisant saillie à l'intérieur du cylindre 2. Une rondelle élastique 7 biconique,en forme de doigt de gant retourné,repose contre le fond du cylindre 2 contre lequel elleest appuyée par un ressort 17 prenant, par ailleurs, appui sur le fond du piston 4 pour solliciter en permanence le cylindre 2 à l'opposé du piston 4.The tubular end piece 39 communicates with the interior of the cylinder 2 by an offset axis 34, parallel to an axial rod 33 projecting inside the cylinder 2. A biconical elastic washer 7, in the form of an inverted glove finger, rests against the bottom of the cylinder 2 against which it is supported by a spring 17 taking, moreover, support on the bottom of the piston 4 to permanently urge the cylinder 2 opposite the piston 4.

La partie conique retournée interne 32 de la rondelle 7 porte élastiquement autour de la tige 33, formant ainsi un clapet non gravimétrique de refoulement qui autorise le passage de la substance lors du refoulement vers la buse 6 par le passage 34, l'embout 39 et le canal 40, mais interdit toute entrée d'air lors de l'aspiration.The internal inverted conical part 32 of the washer 7 bears elastically around the rod 33, thus forming a non-gravimetric delivery valve which allows the passage of the substance during the delivery to the nozzle 6 through the passage 34, the nozzle 39 and channel 40, but prohibits any entry of air during aspiration.

Ainsi, grâce à la combinaison de clapets gravimétrique et non gravimétrique, la pompe suivant l'invention peut fonctionner efficacement en, pratiquement, toutes positions, à condition que l'extrémité du tube plongeur 3, ou le passage radial 10, soit immergé dans la substance à distribuer.Thus, thanks to the combination of gravimetric and non-gravimetric valves, the pump according to the invention can operate efficiently in practically any position, provided that the end of the dip tube 3, or the radial passage 10, is immersed in the substance to distribute.

L'invention permet d'obtenir une efficacité de fonctionnement maximum sur pratiquement 360°, contrairement aux autres systèmes connus, notamment grâce à la disposition des organes moteurs au-dessus du col du récipient, et au logement des organes d'inversion au voisinage immédiat des organes moteurs, dans la carnette du récipient, ce qui réduit au maximum, en position horizontale, le volume annulaire de produit à distribuer entre l'intérieur du col du récipient et le téton tubulaire de la pompe.The invention makes it possible to obtain maximum operating efficiency over practically 360 °, unlike other known systems, in particular thanks to the arrangement of the driving members above the neck of the container, and to the housing of the reversing members. sion in the immediate vicinity of the drive members, in the container bag, which minimizes, in a horizontal position, the annular volume of product to be distributed between the inside of the container neck and the tubular pin of the pump.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et représenté, elle est susceptible de nombreuses variantes accessibles à l'homme de l'art, suivant les applications envisagées sans s'écarter pour cela du cadre de l'invention.Of course, the invention is in no way limited to the embodiment described and shown, it is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged without departing from the scope of the invention.
