Description

Pompe à chemise coulissante Sliding jacket pump
La présente invention concerne une pompe destinée plus particulièrement au dosage et à la distribution de produits cosmétiques liquides tels que des crèmes ou des gels.The present invention relates to a pump intended more particularly for the dosing and dispensing of liquid cosmetic products such as creams or gels.
Les pompes connues qui sont utilisées dans ce type d'application comprennent généralement un corps délimitant une chambre de dosage pourvue en partie basse d'un orifice d'admission et présentant, en partie haute, une ouverture dans laquelle est introduit un manchon porté par une tête d'actionnement à déplacement axial pourvue d'un conduit d'éjection et d'un élément d'obturation et coopérant, par ailleurs, avec un ressort de rappel monté à l'extérieur dudit corps. Cette disposition permet d'éviter que le ressort qui est métallique ne soit au contact du produit et n'entraîne des phénomènes de dégradation physicochimiques.Known pumps which are used in this type of application generally comprise a body delimiting a metering chamber provided in the lower part of an intake orifice and having, in the upper part, an opening in which is introduced a sleeve carried by a axial displacement actuating head provided with an ejection duct and a closure element and cooperating, moreover, with a return spring mounted outside said body. This arrangement makes it possible to prevent the spring which is metallic from being in contact with the product and causing physicochemical degradation phenomena.
Le déplacement de la tête d'actionnement relativement au corps a un effet de piston qui provoque la compression du produit à l'intérieur de la chambre et sa sortie via le conduit d'éjection.The movement of the actuating head relative to the body has a piston effect which causes the product to compress within the chamber and exit via the ejection duct.
L'orifice d'admission est, quant à lui, susceptible d'être obturé, au moins lors de la phase de délivrance du produit, par un clapet généralement à bille. Toutefois, ce clapet est indépendant des autres éléments constitutifs de la pompe et est réalisé sous forme de pièces rapportées sur le corps ce qui crée à la fois des problèmes d'étanchéité, de coordination dans le fonctionnement et des difficultés d'assemblage.The inlet port is, in turn, likely to be closed, at least during the product delivery phase, by a generally ball valve. However, this valve is independent of the other components of the pump and is made in the form of inserts on the body which creates both sealing problems, coordination in operation and assembly difficulties.
De plus, un tel clapet est soumis aux forces de gravité et son fonctionnement peut devenir défectueux dans le cas d'une utilisation de la pompe en position inclinée ou inversée.In addition, such a valve is subjected to the forces of gravity and its operation may become defective in the case of use of the pump in an inclined or inverted position.
La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante.The present invention aims to solve these technical problems satisfactorily.
Ce but est atteint selon l'invention au moyen d'une pompe du type précédent caractérisée en ce que le corps renferme une chemise déplaçable axialement dans ladite chambre et au moins partiellement à l'intérieur du manchon et qui porte un clapet inférieur susceptible de fermer l'orifice d'admission. Selon une caractéristique avantageuse, ladite chemise comporte, en partie basse, une jupe d'étanchéité qui est en contact avec la paroi interne de la chambre.This object is achieved according to the invention by means of a pump of the above type, characterized in that the body encloses an axially displaceable liner. in said chamber and at least partially inside the sleeve and which carries a lower valve capable of closing the inlet port. According to an advantageous characteristic, said jacket comprises, in the lower part, a sealing skirt which is in contact with the inner wall of the chamber.
Selon une autre caractéristique, ladite chemise comporte, en partie haute, une lèvre périphérique qui est en contact de friction étanche avec la paroi interne du manchon.According to another characteristic, said liner comprises, at the top, a peripheral lip which is in sealed frictional contact with the inner wall of the sleeve.
Avantageusement, ladite chemise comporte un épaulement périphérique susceptible de venir en butée avec une saillie annulaire portée par la paroi interne du corps pour limiter sa course vers le haut.Advantageously, said liner has a peripheral shoulder capable of abutting with an annular projection carried by the inner wall of the body to limit its upward stroke.
Selon une variante, ledit clapet comprend une coupelle centrale raccordée à la paroi de ladite chemise par des ailettes radiales. De préférence, ladite coupelle a une section complémentaire de celle de l'orifice d'admission.According to a variant, said valve comprises a central cup connected to the wall of said jacket by radial fins. Preferably, said cup has a section complementary to that of the inlet orifice.
Selon une autre variante, le corps comporte un orifice d'évent débouchant, en partie basse, dans la chambre et susceptible de communiquer avec un compartiment atmosphérique annulaire ménagé à la périphérie de la chemise.According to another variant, the body comprises a vent opening opening, at the bottom, in the chamber and capable of communicating with an annular atmospheric compartment formed at the periphery of the jacket.
Avantageusement, ledit orifice d'évent est susceptible d'être isolé de manière étanche du compartiment atmosphérique par une bavette annulaire portée par la partie inférieure de la chemise.Advantageously, said vent orifice is capable of being sealed from the atmospheric compartment by an annular flap carried by the lower part of the jacket.
De préférence, ladite bavette et ladite jupe délimitent entre elles une gorge périphérique qui vient coiffer une nervure circulaire portée par le fond de la chambre.Preferably, said flap and said skirt delimit between them a peripheral groove which caps a circular rib carried by the bottom of the chamber.
Selon une variante, ledit élément d'obturation du conduit d'éjection est associé à une tige de commande mobile axialement dans ladite chemise. Dans ce cas, il est prévu que ladite chemise comporte un collet supérieur de guidage de ladite tige de commande.According to a variant, said closure element of the ejection duct is associated with a control rod movable axially in said liner. In this case, it is provided that said liner comprises an upper collar for guiding said control rod.
Il est aussi possible de prévoir que la paroi interne de ladite chemise est pourvue d'un jonc de retenue axiale de la tige de commande. Selon une autre caractéristique, le corps est réalisé d'une seule pièce avec une bague de fixation de la pompe sur le col d'un récipient.It is also possible to provide that the inner wall of said liner is provided with an axial retaining ring of the control rod. According to another characteristic, the body is made in one piece with a ring for fixing the pump on the neck of a container.
La pompe de l'invention a une structure simple et de prix de revient économique qui assure un niveau élevé d'étanchéité pour le produit.The pump of the invention has a simple structure and economic cost that ensures a high level of tightness for the product.
Elle permet d'assurer, en outre, un mode de distribution fiable du produit avec un dosage précis et reproductible et offre une adaptabilité et une coopération performante avec différentes variantes de têtes d'actionnement à fermeture d'extrémité.It also ensures reliable dispensing of the product with precise and reproducible dosing and offers adaptability and efficient cooperation with different variants of end-closing actuating heads.
La pompe de l'invention s'applique aussi bien à un distributeur atmosphérique qu'à un distributeur sans reprise d'air (« airless »).The pump of the invention is applicable to both an atmospheric dispenser and a dispenser without air intake ("airless").
Dans une application atmosphérique, la reprise d'air s'effectue selon un mode original qui présente toutes les garanties d'étanchéité et de régularité requises. Dans une application sans reprise d'air et selon le type de récipient utilisé, la pompe peut ne pas comporter d'orifice d'évent.In an atmospheric application, the return air is made in an original mode that has all the guarantees of tightness and regularity required. In an application without air intake and depending on the type of container used, the pump may not have a vent port.

La chemise 3 comporte aussi, en partie basse, une jupe d'étanchéité 31 qui est en contact avec la paroi interne de la chambre.The duct 20 is provided with a shutter element 4, for example, in the form of a valve which, in the embodiment of FIG. 1, is arranged upstream and, in the embodiment of FIG. , is at the downstream end of said duct. According to the invention, the body 1 encloses a cylindrical jacket 3 that is axially displaceable in the chamber and at least partially inside the sleeve 21 and carries a lower valve 30 capable of closing off the inlet orifice 10. The jacket 3 also comprises, in the lower part, a sealing skirt 31 which is in contact with the inner wall of the chamber.
Sur la figure 2, le fond de la chambre porte une nervure circulaire 13 qui s'étend autour de l'orifice 10 et sur la face intérieure de laquelle le bord inférieur de la jupe 31 est en appui étanche.In Figure 2, the bottom of the chamber carries a circular rib 13 which extends around the orifice 10 and on the inside of which the lower edge of the skirt 31 is in sealing engagement.
En partie haute, la chemise 3 comporte une lèvre périphérique 32 qui est en contact de friction étanche avec la paroi interne du manchon 21 et qui assure, en outre, lors du coulissement, le raclage du produit.In the upper part, the liner 3 comprises a peripheral lip 32 which is in sealing friction contact with the inner wall of the sleeve 21 and which further ensures, during sliding, the scraping of the product.
Le volume intérieur de la chemise 3 et celui du manchon 21 jusqu'à l'entrée du conduit d'éjection 20, constitue le volume d'une dose de produit.The internal volume of the liner 3 and that of the sleeve 21 to the inlet of the ejection duct 20 constitutes the volume of a dose of product.
Le clapet d'admission 30 comprend une coupelle centrale 30a raccordée à la paroi de la chemise 3 par un jeu d'ailettes radiales 30b comme représenté sur la figure 4B. La coupelle 30a a, de préférence, une section complémentaire de celle de l'orifice d'admission 10 et a, par exemple ici, une forme tronconique ou bien, selon une variante non représentée, sphérique.The intake valve 30 comprises a central cup 30a connected to the wall of the jacket 3 by a set of radial fins 30b as shown in Figure 4B. The cup 30a preferably has a section complementary to that of the inlet orifice 10 and has, for example here, a frustoconical shape or, according to a variant not shown, spherical.
Dans le cas d'applications atmosphériques, comme pour les modes de réalisation des figures 1 et 2, le corps 1 de la pompe comporte un orifice d'évent 11 débouchant, en partie basse, dans la chambre et susceptible de communiquer avec un compartiment annulaire 33 ménagé à la périphérie de la chemise 3 entre sa paroi externe et la paroi interne du corps 1. L'orifice d'évent 11 est susceptible d'être isolé de manière étanche du compartiment 33, notamment lorsque la pompe est au repos et lors de la phase de délivrance du produit, par une bavette annulaire 35 portée par la partie inférieure de la chemise 3, comme représentée sur les figures 4A et 4B.In the case of atmospheric applications, as for the embodiments of FIGS. 1 and 2, the body 1 of the pump comprises a vent orifice 11 opening, at the bottom, into the chamber and capable of communicating with an annular compartment. 33 formed at the periphery of the liner 3 between its outer wall and the inner wall of the body 1. The vent orifice 11 is capable of being isolated in a sealed manner from the compartment 33, especially when the pump is at rest and when the delivery phase of the product, by an annular flap 35 carried by the lower part of the sleeve 3, as shown in Figures 4A and 4B.
Dans le mode de réalisation de la figure 2, la bavette 35 et la jupe d'étanchéité 31 délimitent entre elles une gorge périphérique 12 qui vient coiffer la nervure circulaire 13 du fond de la chambre. La chemise 3 comporte un épaulement périphérique 36 susceptible de venir en butée étanche avec une saillie annulaire 16 portée par la paroi interne du corps pour limiter la course de ladite chemise vers le haut (voir figures 2, 4A et 4B).In the embodiment of Figure 2, the flap 35 and the sealing skirt 31 delimit between them a peripheral groove 12 which caps the circular rib 13 of the bottom of the chamber. The liner 3 has a peripheral shoulder 36 capable of sealingly abutting with an annular projection 16 carried by the inner wall of the body to limit the stroke of said liner upwards (see FIGS. 2, 4A and 4B).
Dans le mode de réalisation de la figure 2, la portée comprise entre l'extrémité inférieure de la bavette 35 et l'épaulement 36 assure le calage axial de la chemise 3 dans la chambre.In the embodiment of Figure 2, the range between the lower end of the flap 35 and the shoulder 36 ensures the axial setting of the sleeve 3 in the chamber.
Dans le mode de réalisation de la figure 1 , la bavette est très courte et c'est donc sa face supérieure qui délimite l'épaulement 36.In the embodiment of FIG. 1, the flap is very short and it is therefore its upper face that delimits the shoulder 36.
Dans les deux modes de réalisation des figures 1 et 2, l'élément d'obturation 4 est associé à une tige de commande 41 qui est mobile axialement dans la chemise 3. Toutefois, d "autres types de clapets comme, par exemple, un clapet à ressort, conviendraient.In both embodiments of Figures 1 and 2, the closure member 4 is associated with a control rod 41 which is axially movable in the jacket 3. However, other types of valves such as, for example, a spring check valve, would fit.
Dans le mode de réalisation de la figure 1 , l'élément d'obturation 4 est un clapet dont le siège est formé d'une portée tronconique ménagée à la partie supérieure du manchon 21 et qui forme, par ailleurs, un épaulement formant butée haute pour la chemise 3.In the embodiment of FIG. 1, the shut-off element 4 is a valve whose seat is formed of a frustoconical bearing formed at the upper part of the sleeve 21 and which, moreover, forms a shoulder forming a high stop. for the shirt 3.
Dans le mode de réalisation de la figure 2, l'élément d'obturation 4 est un clapet à pointeau 42 rétractable dans le conduit 20.In the embodiment of FIG. 2, the shutter element 4 is a needle valve 42 retractable in the duct 20.
La chemise 3 comporte un collet supérieur 37 de guidage de la tige 41 et cette dernière a un diamètre inférieur au diamètre intérieur de l'alésage central 34 de la chemise 3 pour offrir un passage au produit sortant.The liner 3 comprises an upper flange 37 for guiding the rod 41 and the latter has a diameter smaller than the inside diameter of the central bore 34 of the liner 3 to provide a passage for the outgoing product.
Le passage du produit peut aussi, selon une variante, s'effectuer via des rainures longitudinales ménagées sur la tige 41. Toutefois, la paroi interne de la chemise 3 est pourvue d'un jonc 34a permettant la retenue axiale de l'extrémité de la tige 41 qui présente sur la figure 2 une section chanfreinée. Les figures 3A à 3F illustrent les phases successives de la délivrance du produit avec la pompe de l'invention en version atmosphérique selon la variante de la figure 1. Dans un objectif de clarté, le produit liquide n'y a pas été représenté.The passage of the product can also, according to a variant, be carried out via longitudinal grooves formed on the rod 41. However, the inner wall of the liner 3 is provided with a rod 34a allowing the axial retention of the end of the rod 41 which has in Figure 2 a chamfered section. FIGS. 3A to 3F illustrate the successive phases of the delivery of the product with the pump of the invention in an atmospheric version according to the variant of FIG. 1. For the sake of clarity, the liquid product has not been shown.
La position représentée sur la figure 3A correspond à la position de repos de la pompe.The position shown in Figure 3A corresponds to the rest position of the pump.
Dans cette position, la chambre est remplie de produit et, du fait de la butée de la saillie 23 contre la collerette 14, le ressort R reste légèrement comprimé pour maintenir la tête 2 vers le haut et, par voie de conséquence, l'élément d'obturation 4 en appui étanche sur son siège.In this position, the chamber is filled with product and, because of the abutment of the projection 23 against the collar 14, the spring R remains slightly compressed to maintain the head 2 upwards and, consequently, the element shutter 4 in waterproof support on its seat.
L'étanchéité est renforcée du fait que l'extrémité de la tige 41 de l'élément 4 est tirée vers le bas par son accrochage sur le jonc 34a.The seal is reinforced because the end of the rod 41 of the element 4 is pulled down by its attachment to the rod 34a.
La chemise 3 est ici en position haute et le clapet d'admission 30 est ouvert.The liner 3 is here in the up position and the inlet valve 30 is open.
L'épaulement périphérique 36 est en appui étanche sur la face inférieure de la saillie annulaire 16, empêchant ainsi tout échange entre l'intérieur du récipient et l'extérieur.The peripheral shoulder 36 bears tightly against the underside of the annular projection 16, thus preventing any exchange between the inside of the container and the outside.
La position représentée sur la figure 3B correspond au début de la phase d'appui sur la tête 2 dont la force est matérialisée par une flèche axiale.The position shown in FIG. 3B corresponds to the beginning of the phase of bearing on the head 2, the force of which is represented by an axial arrow.
Le contact de friction entre la lèvre 32 de la chemise 3 et la paroi interne du manchon 21 assure la solidarisation de l'ensemble constitué des deux pièces et de l'élément d'obturation 4 dans leur mouvement conjoint de descente. Le léger serrage résultant de ce contact offre, néanmoins, une résistance supérieure au serrage entre la jupe 31 et la paroi du corps 1.The frictional contact between the lip 32 of the liner 3 and the inner wall of the sleeve 21 secures the assembly consisting of the two parts and the closure element 4 in their joint descent movement. The slight tightening resulting from this contact, however, offers a greater resistance to clamping between the skirt 31 and the wall of the body 1.
Suite à ce mouvement, le clapet 30 vient fermer l'orifice d'admission 10 et interdire ainsi tout refoulement vers le récipient du produit contenu dans la chambre.Following this movement, the valve 30 closes the inlet port 10 and thus prohibit any discharge to the container of the product contained in the chamber.
Parallèlement, la bavette 35 dégage l'orifice d'évent 11 et permet sa communication avec le compartiment annulaire 33 qui est lui-même en communication avec l'extérieur.At the same time, the flap 35 disengages the vent orifice 11 and allows it to communicate with the annular compartment 33 which is itself in communication with the outside.
Sur la figure 3C, l'utilisateur maintient son appui et la tête 2 poursuit donc sa descente alors que la chemise 3 est en butée dans le fond de la chambre. La résistance de friction du contact chemise 3/manchon 21 est vaincue et cède la place à un glissement raclant de la lèvre 32 sur la paroi interne du manchon tandis que ce dernier continue sa course vers le bas.In FIG. 3C, the user maintains his support and the head 2 thus continues to descend while the liner 3 is in abutment in the bottom of the chamber. The frictional resistance of the contact sleeve 3 / sleeve 21 is overcome and gives way to a scraping sliding of the lip 32 on the inner wall of the sleeve while the latter continues its stroke downwards.
Ce mouvement provoque la compression du produit dans la chambre à la manière d'un piston et entraîne le décollement de l'élément d'obturation 4 de son siège pour libérer le produit qui commence ainsi à s'échapper par le conduit 20.This movement causes the product to be compressed in the chamber in the manner of a piston and causes the closure element 4 to disengage from its seat in order to release the product which thus begins to escape through the conduit 20.
Sur la figure 3D, l'appui étant toujours maintenu, l'élément d'obturation 4 vient se plaquer en position ouverte dans le haut contre la paroi interne du conduit 20 et/ou du capot 22.In FIG. 3D, the support being always maintained, the shut-off element 4 is pressed into the open position at the top against the inner wall of the duct 20 and / or the hood 22.
Le manchon 21 poursuit sa course descendante en comprimant le produit dans la chambre jusqu'à ce le bord supérieur de la chemise 3 (lèvre 32 ou collet 37) vienne en butée contre un épaulement 24 de la tête. A ce moment à partir de la chambre, un volume correspondant à une dose de produit a été délivré à l'utilisateur et la phase de distribution est terminée.The sleeve 21 continues its downward stroke by compressing the product in the chamber until the upper edge of the sleeve 3 (lip 32 or collar 37) comes into abutment against a shoulder 24 of the head. At this time from the chamber, a volume corresponding to a dose of product has been delivered to the user and the dispensing phase is complete.
L'orifice d'évent 11 communique avec le compartiment 33 ce qui autorise une mise à l'atmosphère du réservoir de produit (non représenté) et un équilibrage des pressions.The vent port 11 communicates with the compartment 33 which allows venting of the product reservoir (not shown) and a pressure equalization.
L'utilisateur relâche alors la pression et le ressort R rappelle la tête 2 vers le haut comme représenté sur la figure 3E.The user then releases the pressure and the spring R recalls the head 2 upwards as shown in Figure 3E.
Du fait du contact de friction entre la lèvre 32 et la paroi du manchon 21 , la chemise 3 et la tête 2 remontent d'abord solidairement avec le clapet 30 ce qui conduit à l'ouverture de l'orifice d'admission 10.Because of the frictional contact between the lip 32 and the wall of the sleeve 21, the jacket 3 and the head 2 firstly go up integrally with the valve 30, which leads to the opening of the inlet orifice 10.
La dépression crée dans le corps de la pompe par ce déplacement provoque l'aspiration de produit dans le réservoir via le tube de prise 15 et le remplissage progressif de la chambre de dosage.The depression created in the body of the pump by this displacement causes the suction of product into the reservoir via the intake tube 15 and the progressive filling of the metering chamber.
Conjointement, l'orifice d 'évent 11 se ferme par remise en contact de la bavette 35 contre la paroi interne du corps jusqu'à ce que sa face supérieure formant l'épaulement 36 vienne en butée contre la saillie 16 du corps. Très vite toutefois, la résistance de la lèvre 32 cède et le manchon 21 poursuit sa course ascendante indépendamment de la chemise 3 qui reste bloquée en position basse par la butée 16 du corps.At the same time, the vent orifice 11 closes by bringing the flap 35 into contact with the inner wall of the body until its upper face forming the shoulder 36 comes into abutment against the projection 16 of the body. Very quickly, however, the resistance of the lip 32 yields and the sleeve 21 continues its upward movement independently of the sleeve 3 which remains locked in the lower position by the abutment 16 of the body.
L'élément d'obturation 4 retrouve alors sa position d'étanchéité et ferme ainsi le conduit 20 comme représenté sur la figure 3F et pendant cette phase, la chambre continue de se remplir en produit.The sealing member 4 then returns to its sealing position and thus closes the conduit 20 as shown in Figure 3F and during this phase, the chamber continues to fill in product.
Toujours sous l'action du ressort R, la tête 2 poursuit sa course vers le haut et s'immobilise finalement dans la position de repos de la figure 3A, dans l'attente d'une nouvelle distribution.Still under the action of the spring R, the head 2 continues its upward stroke and finally stops in the rest position of Figure 3A, pending a new distribution.
Dans cette dernière position, le conduit 20 est maintenu dans une position de fermeture étanche grâce à l'action du ressort R et tirage sous tension de la tige 41 de l'élément 4 vers le bas au moyen du jonc 34a.In the latter position, the conduit 20 is held in a sealed position by the action of the spring R and draw tension of the rod 41 of the element 4 downwards by means of the rod 34a.
Bien entendu, cette pompe peut aussi être réalisée sans orifice d'évent dans le cas d'une utilisation sans reprise d'air dite « airless ». Of course, this pump can also be performed without vent port in the case of use without air intake called "airless".
