Description

La présente invention concerne un distributeur duo comprenant deux pompes associées respectivement à deux réservoirs de produits fluides différents. Les deux pompes comprennent chacune un corps de pompe fixe et une tige d'actionnement déplaçable axialement sur une course axiale. Le distributeur duo comprend aussi une tête de distribution commune ayant un canal de sortie formant un orifice de distribution pour les produits fluides issus des tiges d'actionnement des deux pompes. Les domaines privilégiés de l'invention sont ceux de la cosmétique et de la pharmacie.The present invention relates to a duo dispenser comprising two pumps associated respectively with two reservoirs of different fluid products. The two pumps each comprise a stationary pump body and an actuating rod movable axially on an axial stroke. The duo distributor also comprises a common distribution head having an outlet channel forming a distribution orifice for the fluid products coming from the actuating rods of the two pumps. The privileged fields of the invention are those of cosmetics and pharmacy.

Dans l'art antérieur, on connaît déjà des distributeurs duo à doses réglables. Selon un mode de réalisation répandu, le distributeur comprend une bague rotative qui forme intérieurement une rampe ou des gradins annulaires qui servent de butée axiale pour un poussoir, limitant ainsi la course d'actionnement et de ce fait la dose de produit fluide distribuée. Les bagues à rampe permettent une variation continue des doses et les bagues à gradins permettent une variation étagée des doses. Extérieurement, la bague rotative forme un organe de préhension que l'utilisateur peut saisir pour entraîner la bague en rotation. Des indications ou des curseurs sont prévus sur la bague rotative ou à proximité directe pour informer l'utilisateur du positionnement précis de la bague, et ainsi du réglage des doses. Le document US 2004/251274 A1 divulgue un distributeur duo avec un insert de réglage (10) comportant des fenêtres (9) donnant accès à l'insert de réglage et permettant de régler les proportions des produits P1 et P2 dans le mélange distribué. Ledit insert étant donc indépendant du bouton poussoir.In the prior art, dual dispensers with adjustable doses are already known. According to a widespread embodiment, the dispenser comprises a rotating ring which internally forms a ramp or annular steps which serve as an axial stop for a pusher, thus limiting the actuation stroke and therefore the dose of fluid dispensed. Ramp rings allow a continuous variation of the doses and the stepped rings allow a staged variation of the doses. Externally, the rotating ring forms a gripping member that the user can grip to drive the ring in rotation. Indications or cursors are provided on the rotating ring or in close proximity to inform the user of the precise positioning of the ring, and thus of the dose setting. The document US 2004/251274 A1 discloses a duo dispenser with an adjustment insert (10) comprising windows (9) giving access to the adjustment insert and making it possible to adjust the proportions of the products P1 and P2 in the mixture distributed. Said insert therefore being independent of the push button.

Le document DE 39 11 089 A1 divulgue un insert de réglage formé par une couronne ou roue externe directement accessible par l'utilisateur.The document DE 39 11 089 A1 discloses an adjustment insert formed by an external crown or wheel directly accessible by the user.

Le document FR 2 909 982 A1 divulgue un poussoir ayant une fenêtre allongée 98. L'insert de réglage (89) s'étendant à travers cette fenêtre 98 et étant déplaçable de cette fenêtre de manière à faire tourner une bague (8) à l'intérieur du poussoir 9 qui lui est bloqué en rotation.The document FR 2 909 982 A1 discloses a pusher having an elongated window 98. The adjustment insert (89) extending through this window 98 and being movable from this window so as to rotate a ring (8) inside the pusher 9 which thereto. is blocked in rotation.

Le document WO 2010/003091 divulgue une came déplaçable par actionnement d'un élément glissant indépendant du bouton poussoir.The document WO 2010/003091 discloses a movable cam by actuation of a sliding element independent of the push button.

La présente invention cherche à définir un distributeur duo dont le réglage de doses est plus discret en supprimant la bague rotative préhensible, qui est clairement visible et qui confère au distributeur un côté technique marqué. En d'autres termes, le but de l'invention est de conserver une bague rotative apte à limiter les hauteurs de course des tiges d'actionnement, mais de rendre l'organe de préhension le plus discret possible. Un objectif de l'invention est de confondre l'organe de préhension avec un autre organe du distributeur, de manière à l'intégrer parfaitement.The present invention seeks to define a duo dispenser whose dose adjustment is more discreet by eliminating the gripping rotary ring, which is clearly visible and which gives the dispenser a marked technical aspect. In other words, the aim of the invention is to keep a rotary ring capable of limiting the stroke heights of the actuating rods, but to make the gripping member as discreet as possible. An objective of the invention is to confuse the gripping member with another part of the distributor, so as to integrate it perfectly.

Pour ce faire, la présente invention propose que la tête de distribution commune comprenne :

  • une coiffe montée sur les tiges d'actionnement et formant l'orifice de distribution,
  • un poussoir monté sur la coiffe pour la déplacer axialement en va-et-vient, le poussoir étant en outre monté rotatif sur et par rapport à la coiffe, et
  • un insert de réglage disposé en-dessous de la coiffe et solidaire du poussoir de manière à tourner avec lui, la coiffe venant en butée sur l'insert de réglage, limitant ainsi la course axiale des tiges d'actionnement.
To do this, the present invention proposes that the common distribution head comprises:
  • a cap mounted on the actuating rods and forming the dispensing orifice,
  • a pusher mounted on the cap to move it axially back and forth, the pusher being further rotatably mounted on and relative to the cap, and
  • an adjustment insert arranged below the cover and integral with the pusher so as to rotate with it, the cover abutting on the adjustment insert, thus limiting the axial travel of the actuating rods.

Ainsi, c'est le poussoir rotatif qui remplit la fonction supplémentaire d'organe de préhension et d'actionnement de l'insert de réglage. On peut aussi dire que les fonctions de limitation de course et d'actionnement sont dissociées : la fonction de limitation étant assurée par l'insert de réglage et la fonction d'actionnement de l'insert de réglage étant assurée par le poussoir. L'organe d'actionnement de l'insert de réglage est confondu avec le poussoir, dont la fonction première et conventionnelle est d'actionner les tiges d'actionnement des pompes. Il est de ce fait possible de masquer ou dissimuler parfaitement l'organe d'actionnement de l'insert de réglage en ne donnant que peu d'information, voire aucune, sur la fonction supplémentaire du poussoir. Le distributeur peut alors présenter une configuration conventionnelle, à savoir celle d'un distributeur ne comprenant qu'un réservoir et seule une pompe.Thus, it is the rotary plunger which fulfills the additional function of gripping and actuating member of the adjustment insert. It can also be said that the stroke limitation and actuation functions are separate: the limitation function being provided by the adjustment insert and the actuation function of the adjustment insert being provided by the push-button. The actuator of the adjustment insert is the same as the pusher, the primary and conventional function of which is to actuate the actuating rods of the pumps. It is therefore possible to perfectly hide or conceal the actuator of the adjustment insert by giving little or no information on the additional function of the pusher. The dispenser can then have a conventional configuration, namely that of a dispenser comprising only one reservoir and only one pump.

Avantageusement, la coiffe appuie l'insert de réglage sur les corps de pompe en fin de course du poussoir. Ainsi, l'insert de réglage est pris en sandwich entre la coiffe et les corps de pompe.Advantageously, the cap rests the adjustment insert on the pump bodies at the end of the stroke of the pusher. Thus, the adjustment insert is sandwiched between the cover and the pump bodies.

Selon un mode de réalisation avantageux, l'insert de réglage comprend une platine de réglage formant deux ouvertures de passage pour les deux tiges d'actionnement. La platine de réglage est prise en sandwich entre la coiffe et les corps de pompe. Avantageusement, les ouvertures de passage sont bordées par des plages de butée de hauteurs axiales différentes. De préférence, la platine de réglage présente des épaisseurs de paroi différentes au niveau des plages de butée. Les ouvertures de passage peuvent présenter une forme de haricot.According to an advantageous embodiment, the adjustment insert comprises an adjustment plate forming two passage openings for the two actuating rods. The adjustment plate is sandwiched between the cover and the pump bodies. Advantageously, the passage openings are bordered by stop areas of different axial heights. Preferably, the adjustment plate has different wall thicknesses at the level of the abutment areas. The passage openings may have the shape of a bean.

Selon un autre aspect avantageux de l'invention, l'insert de réglage est connecté au poussoir par une broche axiale qui traverse la coiffe, le poussoir formant un logement dans lequel la broche axiale est reçue en étant bloquée en rotation. Ainsi, la coiffe est interposée entre le poussoir et la platine de réglage avec la broche axiale traversant la coiffe de manière centrée. Le poussoir et l'insert de réglage tournent ensemble autour d'un axe passant par la broche axiale, alors que la coiffe qui est disposée entre eux est fixe en rotation. Par ailleurs, le poussoir se déplace axialement en entraînant avec lui la coiffe. D'autre part, la broche axiale de l'insert peut coulisser, avec ou sans frottement, dans le logement du poussoir. Avantageusement, la broche axiale présente une section transversale polygonale adaptée à coopérer avec le logement du poussoir pour un entrainement en rotation et un coulissement axial. Le poussoir peut être limité en rotation par l'insert de réglage engagé autour des tiges d'actionnement. Avantageusement, la coiffe comprend deux manchons de raccordement qui viennent en butée sur des plages de butée. En variante, le sommet des corps de pompe pourrait venir en butée avec les plages de butée.According to another advantageous aspect of the invention, the adjustment insert is connected to the pusher by an axial pin which passes through the cap, the pusher forming a housing in which the axial pin is received while being locked in rotation. Thus, the cap is interposed between the pusher and the adjustment plate with the axial pin passing through the cap in a centered manner. The pusher and the adjustment insert rotate together around an axis passing through the axial spindle, while the cap which is arranged between them is fixed in rotation. Furthermore, the pusher moves axially, taking the cap with it. On the other hand, the axial pin of the insert can slide, with or without friction, in the housing of the pusher. Advantageously, the axial spindle has a polygonal cross section adapted to cooperate with the housing of the pusher for driving in rotation and axial sliding. The pusher can be limited in rotation by the adjustment insert engaged around the actuating rods. Advantageously, the cap comprises two connection sleeves which abut on the abutment pads. As a variant, the top of the pump bodies could come into abutment with the abutment pads.

Selon une autre caractéristique avantageuse, l'orifice de distribution est engagé dans une fenêtre formée par un capot d'habillage, l'orifice de distribution se déplaçant axialement dans cette fenêtre par appui sur le poussoir. Le poussoir peut être engagé dans le capot d'habillage, masquant ainsi l'insert de réglage et la coiffe, hormis au niveau de son orifice de distribution qui est engagé dans la fenêtre.According to another advantageous characteristic, the dispensing orifice is engaged in a window formed by a covering cover, the dispensing orifice moving axially in this window by pressing on the pusher. The pusher can be engaged in the covering cover, thus masking the adjustment insert and the cover, except at the level of its dispensing orifice which is engaged in the window.

L'esprit de l'invention réside dans le fait d'intégrer ou de déporter l'actionnement des moyens de réglage de doses dans un organe classique du distributeur, et notamment son poussoir, de sorte que le distributeur duo peut retrouver une configuration classique de distributeur mono (un réservoir et une pompe). Le fait de relier le poussoir à l'insert de réglage à travers la coiffe est une caractéristique intéressante.The spirit of the invention lies in the fact of integrating or deporting the actuation of the dose adjustment means in a conventional member of the dispenser, and in particular its pusher, so that the dual dispenser can find a classic configuration of mono distributor (one tank and one pump). An interesting feature is the connection of the pusher to the adjustment insert through the cap.

L'invention sera maintenant décrite plus en détail en référence aux dessins joints, donnant à titre d'exemple non limitatif, un mode de réalisation de l'invention.The invention will now be described in more detail with reference to the accompanying drawings, giving by way of non-limiting example, one embodiment of the invention.

On se référera tout d'abord à la figure 1 pour décrire en détail tous les éléments constitutifs du distributeur de l'invention. Très brièvement, le distributeur comprend un réservoir principal R1 formant une coque extérieure, un étui 6 formant un réservoir secondaire R2 (figures 6 et 7), un couvercle 5 monté sur les deux réservoirs R1 et R2 et servant de support à deux pompes P1 et P2 munies de tubes plongeurs T1 et T2. Chaque pompe comprend un corps de pompe P10, P20 ainsi qu'une tige d'actionnement ou de soupape P11, P21 qui coulisse axialement en va-et-vient. La partie supérieure du distributeur comprend une coiffe 1 montée sur les extrémités libres D2 tige de soupape P11, P21 et définissant un canal interne qui mène à un gicleur 15 formant un orifice de distribution O. Cette partie supérieure du distributeur comprend également un poussoir 2 monté sur la coiffe 1 pour la déplacer axialement en enfonçant les tiges de soupape P11, P21. Cette partie supérieure du distributeur comprend aussi un capot d'habillage 4 qui est monté sur le réservoir principal R1 de manière à masquer tous les éléments constitutifs, excepté le poussoir 2 et le gicleur 15. Selon l'invention, la partie supérieure du distributeur comprend également un insert de réglage 3 qui permet de faire varier les courses des tiges d'actionnement P11, P21, et ainsi les doses de produits fluides distribuées par les pompes P1, P2. Telle est l'architecture globale du distributeur selon cette forme de réalisation de l'invention.We will first of all refer to the figure 1 to describe in detail all the constituent elements of the dispenser of the invention. Very briefly, the dispenser comprises a main reservoir R1 forming an outer shell, a case 6 forming a secondary reservoir R2 ( figures 6 and 7 ), a cover 5 mounted on the two reservoirs R1 and R2 and serving as a support for two pumps P1 and P2 fitted with dip tubes T1 and T2. Each pump comprises a pump body P10, P20 as well as an actuating or valve rod P11, P21 which slides axially back and forth. The upper part of the distributor comprises a cover 1 mounted on the free ends D2 valve stem P11, P21 and defining an internal channel which leads to a nozzle 15 forming a distribution orifice O. This upper part of the distributor also comprises a pusher 2 mounted on the cover 1 to move it axially by pushing in the valve stems P11, P21. This upper part of the dispenser also comprises a covering cover 4 which is mounted on the main reservoir R1 so as to hide all the constituent elements, except the pusher 2 and the nozzle 15. According to the invention, the upper part of the dispenser also comprises an adjustment insert 3 which makes it possible to vary the strokes of the actuating rods P11, P21, and thus the doses of fluid products distributed by the pumps P1, P2. This is the overall architecture of the distributor according to this embodiment of the invention.

Sur la figure 2, on ne voit que la partie supérieure du distributeur comprenant la coiffe 1, le poussoir 2, l'insert de réglage 3 et le capot d'habillage 4. Le poussoir 2 comprend des moyens d'accrochage 21 destinés à coopérer avec des profils d'accrochage 14 formés par la coiffe 1. Ainsi, le poussoir 2 est solidaire en déplacement axial de la coiffe 1. Toutefois, le poussoir 2 est libre en rotation par rapport à la coiffe 1.On the figure 2 , we see only the upper part of the dispenser comprising the cover 1, the pusher 2, the adjustment insert 3 and the covering cover 4. The pusher 2 comprises hooking means 21 intended to cooperate with the profiles of 'hooking 14 formed by the cap 1. Thus, the pusher 2 is integral in axial displacement of the cap 1. However, the pusher 2 is free to rotate relative to the cap 1.

La coiffe 1 comprend deux manchons de raccordement 11 et 12 qui sont adaptés à venir s'emmancher sur les extrémités libres des tiges d'actionnement P11 et P21 des deux pompes. Bien que non visible, un canal interne relie ces deux manchons de raccordement 11 et 12 à un logement gicleur 13 qui débouche latéralement. Ce logement de gicleur 13 reçoit un gicleur 15 formant un orifice de distribution O. Le gicleur 15 peut distribuer le mélange de produit fluide sous diverses formes : spray, filet, noisette, etc. La coiffe 1 comprend également un passage central axial vertical 10 qui s'étend sensiblement entre les deux manchons de raccordement 11 et 12.The cover 1 comprises two connection sleeves 11 and 12 which are adapted to fit onto the free ends of the actuating rods P11 and P21 of the two pumps. Although not visible, an internal channel connects these two connection sleeves 11 and 12 to a nozzle housing 13 which opens out laterally. This nozzle housing 13 receives a nozzle 15 forming a distribution orifice O. The nozzle 15 can distribute the fluid mixture in various forms: spray, net, hazelnut, etc. The cover 1 also comprises a vertical axial central passage 10 which extends substantially between the two connection sleeves 11 and 12.

L'insert de réglage 3 comprend une platine de réglage 31 formant deux ouvertures de passage 32 pour les deux tiges d'actionnement P11, P21. L'insert de réglage 3 comprend également une broche axiale 34 qui s'étend vers le haut à partir de la platine de réglage 31. Cette broche axiale 34 présente une section transversale de forme polygonale ou toute autre forme permettant de la bloquer en rotation. Cette broche axiale 34 peut être pourvue d'un ou plusieurs profils d'encliquetage 34a.The adjustment insert 3 comprises an adjustment plate 31 forming two passage openings 32 for the two actuating rods P11, P21. The adjustment insert 3 also comprises an axial pin 34 which extends upwards from the adjustment plate 31. This axial pin 34 has a cross section of polygonal shape or any other shape allowing it to be blocked in rotation. This axial pin 34 can be provided with one or more snap-fit profiles 34a.

Le capot d'habillage 4 présente ici une forme ogivale non limitative. Le capot est percé d'une fenêtre oblongue 45 destinée à recevoir le gicleur 15. La forme oblongue verticale permet au gicleur 15 de se déplacer axialement lorsque l'on appuie sur le poussoir 2.The covering cover 4 here has a non-limiting ogival shape. The cover is pierced with an oblong window 45 intended to receive the nozzle 15. The vertical oblong shape allows the nozzle 15 to move axially when the push-button 2 is pressed.

On se référera maintenant aux figures 3 et 4 pour expliquer la structure fine de l'insert de réglage 3 et sa coopération avec les tiges de soupape P11 et P21. Comme susmentionné, les deux tiges de soupape P11 et P21 s'étendent à travers les ouvertures de passage 32 formées par la platine de réglage 31 de l'insert de réglage 3. On peut remarquer que les ouvertures de passage 32 sont disposées de manière symétrique autour de la broche axiale 34, et présentent avantageusement une forme de haricot ou de rein. On comprend aisément que la platine de réglage 31 peut être déplacée en rotation autour d'un axe vertical passant par la broche axiale 34, de sorte que les tiges d'actionnement P11 et P21 se déplacent à l'intérieur des ouvertures de passage 32. On peut également remarquer que les ouvertures de passage 32 sont bordées par des plages de butée 33h, 33l et 33i qui présentent des hauteurs axiales différentes. Ceci est plus clairement visible sur la figure 4. Les plages de butée intermédiaires 33i forment des rampes qui permettent de relier les plages de butée hautes 33h aux plages de butée basses 33l. Ainsi, pour une même ouverture de passage 32, ces plages de butée sont reliées entre elles pour former une boucle continue fermée qui définit le bord de l'ouverture de passage 32. Les plages de butée hautes 33h correspondent à une épaisseur maximale de la platine de réglage 31, alors que les plages de butée basses 33l correspondent à une épaisseur minimale de la platine de réglage 31. Ainsi, en fonction de leur positionnement dans les ouvertures de passage 32, les tiges de soupape P11 et P21 sont soit bordées principalement par les plages de butée hautes 33h, soit bordées principalement par les plages de butée basses 33l.We will now refer to figures 3 and 4 to explain the fine structure of the adjustment insert 3 and its cooperation with the valve stems P11 and P21. As mentioned above, the two valve stems P11 and P21 extend through the passage openings 32 formed by the adjustment plate 31 of the adjustment insert 3. It can be noted that the passage openings 32 are arranged symmetrically. around the axial pin 34, and advantageously have the shape of a kidney or kidney. It is easily understood that the adjustment plate 31 can be moved in rotation about a vertical axis passing through the axial spindle 34, so that the actuating rods P11 and P21 move inside the passage openings 32. It can also be noted that the passage openings 32 are bordered by abutment areas 33h, 33l and 33i which have different axial heights. This is more clearly visible on the figure 4 . The intermediate stop areas 33i form ramps which make it possible to connect the high stop areas 33h to the low stop areas 33l. Thus, for the same passage opening 32, these stop areas are interconnected to form a closed continuous loop which defines the edge of the passage opening 32. The upper stop areas 33h correspond to a maximum thickness of the plate. adjustment 31, while the lower stop ranges 33l correspond to a minimum thickness of the adjustment plate 31. Thus, depending on their positioning in the passage openings 32, the valve stems P11 and P21 are either bordered mainly by the high stop ranges 33h, or bordered mainly by the low stop zones 33l.

Sur la figure 5, on peut voir le distributeur à l'état monté, qui ne laisse apparaître que le réservoir principal R1, le capot d'habillage 4, le poussoir 2 et le gicleur 15 positionné dans la fenêtre oblongue 45 de l'habillage 4. En appuyant sur le poussoir 2, le gicleur 15 se déplace axialement dans la fenêtre oblongue 45 et distribue un mélange de produits fluides.On the figure 5 , we can see the distributor in the mounted state, which only lets appear the main tank R1, the covering cover 4, the push button 2 and the nozzle 15 positioned in the oblong window 45 of the covering 4. By pressing on the pusher 2, the nozzle 15 moves axially in the oblong window 45 and dispenses a mixture of fluid products.

En se référant à la figure 6, on peut tout de suite remarquer que la coiffe 1 est interposée entre le poussoir 2 et la platine de réglage 31 de l'insert de réglage 3. La broche axiale 34 de l'insert de réglage 3 passe à travers le passage central axial vertical 10 de la coiffe 1 et vient s'engager à l'intérieur d'un logement 23 formé par le poussoir 2. Ce logement 23 présente une section transversale qui coopère avec la broche axiale 34 de section transversale polygonale de manière à empêcher toute rotation relative entre le poussoir 2 et l'insert de réglage 3. La broche 34 et le logement 23 peuvent par exemple présenter une section carrée, hexagonale ou encore en forme de de croix ou d'étoile. La broche 34 est ainsi bloquée en rotation dans le logement 23, de sorte que l'insert de réglage est solidaire en rotation du poussoir 2. Cependant, la broche 34 peut coulisser axialement, librement ou avec un léger frottement, dans le logement 23 sur une petite course axiale, qui peut être limitée par le profil d'encliquetage 34a. C'est pourquoi on peut constater un petit espace de débattement 24 dans le logement 23 au-dessus de la broche axiale 34. Quant à la coiffe 1, elle est montée fixement en rotation, du fait qu'elle est emmanchée sur les tiges d'actionnement P11 et P21. Ainsi, le poussoir 2 et son insert de réglage 3 peuvent tourner autour d'un axe vertical passant par la broche axiale 34 sur une course angulaire qui est limitée par les ouvertures de passage 32. Dans cet exemple non limitatif, l'angle de rotation du poussoir et de l'insert est de l'ordre de 45 à 60°. Cet angle peut bien entendu varier en modifiant la forme ou plus particulièrement la longueur des ouvertures de passage 32.With reference to the figure 6 , we can immediately notice that the cap 1 is interposed between the pusher 2 and the adjustment plate 31 of the adjustment insert 3. The axial pin 34 of the adjustment insert 3 goes to through the vertical axial central passage 10 of the cover 1 and engages inside a housing 23 formed by the pusher 2. This housing 23 has a cross section which cooperates with the axial pin 34 of polygonal cross section of so as to prevent any relative rotation between the pusher 2 and the adjustment insert 3. The pin 34 and the housing 23 may for example have a square, hexagonal or even cross or star shaped section. The spindle 34 is thus locked in rotation in the housing 23, so that the adjustment insert is integral in rotation with the pusher 2. However, the spindle 34 can slide axially, freely or with a slight friction, in the housing 23 on a small axial travel, which can be limited by the ratchet profile 34a. This is why we can see a small clearance 24 space in the housing 23 above the axial spindle 34. As for the cap 1, it is mounted fixedly in rotation, because it is fitted on the rods of 'actuation P11 and P21. Thus, the pusher 2 and its adjustment insert 3 can rotate about a vertical axis passing through the axial spindle 34 over an angular travel which is limited by the passage openings 32. In this non-limiting example, the angle of rotation of the pusher and of the insert is of the order of 45 to 60 °. This angle can of course vary by modifying the shape or more particularly the length of the passage openings 32.

On peut remarquer que les manchons de raccordement 11 et 12 viennent en contact ou en butée avec la face supérieure de la platine de réglage 31 au niveau des plages de butée bordant les ouvertures de passage 32. Sur la figure 6, les manchons de raccordement 11 et 12 viennent en butée avec les plages de butée hautes 33h, correspondant à l'épaisseur maximale de la platine de réglage 31. Sur la figure 6 correspondant à l'état de repos, les tiges d'actionnement P11 et P21 sont étendues au maximum, de sorte que la platine de réglage 31 est disposée en éloignement des corps de pompe P10 et P20.It can be noted that the connection sleeves 11 and 12 come into contact or abut with the upper face of the adjustment plate 31 at the level of the abutment areas bordering the passage openings 32. On the figure 6 , the connection sleeves 11 and 12 come into abutment with the upper abutment areas 33h, corresponding to the maximum thickness of the adjustment plate 31. On the figure 6 corresponding to the rest state, the actuating rods P11 and P21 are extended to the maximum, so that the adjustment plate 31 is disposed away from the pump bodies P10 and P20.

On peut comprendre qu'en tournant le poussoir 2 l'insert de réglage va être entraîné en rotation, déplaçant ainsi les ouvertures de passage 32 autour des tiges de soupape P11, P21. En partant de la position représentée sur la figure 6 correspondant à des tiges de soupape P11, P21 situées au niveau des plages de butée hautes 33h, on peut faire tourner le poussoir de manière à amener les tiges de soupape P11 et P21 au niveau des plages de butée basses 33l.It can be understood that by turning the pusher 2 the adjustment insert will be driven in rotation, thus moving the passage openings 32 around the valve stems P11, P21. Starting from the position shown on the figure 6 corresponding to valve rods P11, P21 located at the level of the upper stop areas 33h, the tappet can be rotated so as to bring the valve rods P11 and P21 to the level of the lower stop areas 33l.

Sur la figure 7, le distributeur est dans un état actionné ou enfoncé, correspondant à un appui axial sur le poussoir 2. L'ensemble formé par le poussoir 2, l'insert 3 et la coiffe 1 a été déplacé vers le bas en enfonçant les tiges de soupape P11 et P21. On peut remarquer que la platine de réglage 31 est alors en butée sur les corps de pompe P10 et P20. Du fait de l'interposition de la platine de réglage 31 entre les manchons de raccordement 11, 12 et les corps de pompe P10, P20, les tiges de soupape P11 et P21 n'ont pas été enfoncées complètement, limitant la course axiale des tiges de soupape, réduisant ainsi le volume de la dose de produit fluide distribuée. La platine de réglage 31 remplit ainsi un rôle d'entretoise entre les manchons 11, 12 et les corps de pompe P10, P20. En faisant tourner le poussoir 2, et de ce fait la platine de réglage 31, on peut augmenter le volume des doses distribuées en positionnant les plages de butée basses 33l autour des manchons de raccordement 11, 12. Les manchons pourront alors pénétrer dans la platine de réglage 31 jusqu'à venir en butée avec les plages de butée basses 33l. Ceci nécessite un léger déplacement de l'insert de réglage 3 par rapport au poussoir 2, rendu possible par le petit espace de débattement 24 situé au sommet du logement 23, dans lequel peut pénétrer la broche axiale 34.On the figure 7 , the distributor is in an actuated or depressed state, corresponding to an axial bearing on the tappet 2. The assembly formed by the tappet 2, the insert 3 and the cover 1 has been moved downwards by pressing the valve stems P11 and P21. It can be noted that the adjustment plate 31 is then in abutment on the pump bodies P10 and P20. Due to the interposition of the adjustment plate 31 between the connection sleeves 11, 12 and the pump bodies P10, P20, the valve stems P11 and P21 were not inserted completely, limiting the axial travel of the stems valve, thus reducing the volume of the dose of fluid dispensed. The adjustment plate 31 thus fulfills the role of a spacer between the sleeves 11, 12 and the pump bodies P10, P20. By rotating the pusher 2, and therefore the adjustment plate 31, the volume of the doses dispensed can be increased by positioning the bottom stop areas 33l around the connection sleeves 11, 12. The sleeves can then enter the plate. adjustment 31 until it comes to a stop with the lower end stops 33l. This requires a slight movement of the adjustment insert 3 relative to the pusher 2, made possible by the small clearance 24 located at the top of the housing 23, into which the axial spindle 34 can penetrate.

On peut ainsi faire varier les doses de produit fluide distribuées en faisant très simplement tourner le poussoir 2. On peut ainsi dire que l'organe d'actionnement de l'insert de réglage 3 est formé ou constitué par le poussoir 2. Cela permet d'avoir une configuration tout à fait classique pour un distributeur, comme on peut le voir sur la figure 5. En effet, ce distributeur ne laisse pas apparaitre qu'il comprend deux réservoirs et deux pompes, et de surcroit, il ne comprend pas d'organe d'actionnement spécifique pour régler les doses de produit fluide distribuées, étant donné que c'est le poussoir 2 qui remplit cette fonction.It is thus possible to vary the doses of fluid product dispensed by very simply turning the pusher 2. It can thus be said that the actuator of the adjustment insert 3 is formed or constituted by the pusher 2. This makes it possible to '' have a completely classic configuration for a distributor, as can be seen on the figure 5 . Indeed, this dispenser does not show that it comprises two reservoirs and two pumps, and in addition, it does not include a specific actuator to adjust the doses of fluid dispensed, given that it is the push-button 2 which fulfills this function.

Sur les figures, les plages de butée 33h, 33l, 33i sont situées du même côté que la broche axiale 34. En variante, les plages de butée pourraient être situées sur le côté opposé de la platine de réglage et coopérer avec les parties supérieures des corps de pompe P10, P11 ou des rondelles engagées autour des tiges de soupape et reposant sur les parties supérieures des corps de pompe P10, P11.In the figures, the stop areas 33h, 33l, 33i are located on the same side as the axial spindle 34. As a variant, the stop areas could be located on the opposite side of the adjustment plate and cooperate with the upper parts of the pump casing P10, P11 or washers engaged around the valve stems and resting on the upper parts of pump casings P10, P11.

Sur les figures, la platine de réglage 31 forme deux plages de butée stables, à savoir la plage haute 33h et la plage basse 33l. Sans sortir du cadre de l'invention, la platine de réglage 31 peut former plus de deux plages de butée stables, en prévoyant par exemple une ou plusieurs plages intermédiaires stables à la place de la plage intermédiaire instable 33i.In the figures, the adjustment plate 31 forms two stable stop ranges, namely the high range 33h and the lower range 33l. Without departing from the scope of the invention, the adjustment plate 31 can form more than two stable stop ranges, for example by providing one or more stable intermediate ranges instead of the unstable intermediate range 33i.

Dans le mode de réalisation décrit, l'orifice de distribution est commun. On peut toutefois envisager un orifice de distribution ayant deux sorties de produit fluide, sans pour autant sortir du cadre de l'invention.In the embodiment described, the dispensing orifice is common. It is however possible to envisage a dispensing orifice having two fluid product outlets, without however departing from the scope of the invention.

On peut également voir sur les figures 6 et 7 que l'étui 6 forme le réservoir secondaire R2, ainsi qu'un manchon 62 qui repose sur un épaulement interne du réservoir R1. Ainsi, le tube plongeur T1 puise un produit fluide contenu dans le réservoir secondaire R2, alors que le tube plongeur T2 puise directement dans le réservoir principal R1 pour distribuer un autre produit fluide, qui est avantageusement différent du produit fluide du réservoir secondaire R2. Le couvercle 5 est monté à la fois sur l'étui 6 et sur le réservoir principal R1 et supporte les deux corps de pompe P10 et P20 de manière stable et étanche. Il ne s'agit là que de caractéristiques qui ne sont en aucun cas limitatives pour l'invention.We can also see on the figures 6 and 7 that the case 6 forms the secondary reservoir R2, as well as a sleeve 62 which rests on an internal shoulder of the reservoir R1. Thus, the dip tube T1 draws a fluid product contained in the secondary reservoir R2, while the dip tube T2 draws directly from the main reservoir R1 to dispense another fluid product, which is advantageously different from the fluid product of the secondary reservoir R2. The cover 5 is mounted both on the case 6 and on the main reservoir R1 and supports the two pump bodies P10 and P20 in a stable and sealed manner. These are only characteristics which are in no way limiting for the invention.

Grâce à l'invention, on dispose d'un distributeur duo à dose réglable au moyen du poussoir. Cela permet de réaliser un distributeur duo ayant l'apparence d'un distributeur simple ne comprenant qu'un réservoir, une pompe et un poussoir. En fonction des informations apposées sur le distributeur, l'utilisateur est plus ou moins bien informé de la fonction supplémentaire du poussoir.Thanks to the invention, there is a duo dispenser with an adjustable dose by means of the pusher. This makes it possible to produce a duo dispenser having the appearance of a simple dispenser comprising only a reservoir, a pump and a pusher. Depending on the information affixed to the dispenser, the user is more or less well informed of the additional function of the pusher.
