Description

Distributeur de produit fluide  Fluid dispenser
La présente invention concerne un distributeur de produit fluide comprenant deux réservoirs, deux pompes et deux poussoirs, à savoir un premier poussoir pour actionner une première pompe reliée à un premier réservoir contenant un premier produit fluide, et un deuxième poussoir pour actionner une deuxième pompe reliée à un deuxième réservoir contenant un deuxième produit fluide. Les domaines d'application privilégiés de la présente invention sont ceux de la parfumerie, de la cosmétique ou encore de la pharmacie. The present invention relates to a fluid dispenser comprising two tanks, two pumps and two pushers, namely a first pusher for actuating a first pump connected to a first reservoir containing a first fluid, and a second pusher for actuating a second pump connected. to a second reservoir containing a second fluid product. The preferred fields of application of the present invention are those of perfumery, cosmetics or even pharmacy.
Dans l'art antérieur on connaît déjà des distributeurs de type duo comprenant deux réservoirs, deux pompes et un poussoir commun permettant l'actionnement simultané des deux pompes. On connaît également des systèmes de répartition permettant de faire varier les doses de produit fluide distribuées par les deux pompes. Ainsi, en appuyant sur le poussoir commun, on peut distribuer uniquement du produit fluide issu de la première pompe, du produit fluide issu de la deuxième pompe, ou un mélange plus ou moins dosé des produits fluides issus des deux pompes simultanément.  In the prior art duo type distributors are already known comprising two tanks, two pumps and a common pusher for the simultaneous actuation of the two pumps. Distribution systems are also known for varying the doses of fluid dispensed by the two pumps. Thus, by pressing the common pusher, it is possible to dispense only the fluid product from the first pump, the fluid product from the second pump, or a more or less proportioned mixture of the fluid products from the two pumps simultaneously.
Le document FR2793479 décrit un distributeur de type duo comprenant deux poussoirs dépourvus d'orifice de distribution et un poussoir commun qui agit simultanément sur les deux poussoirs et qui forme un orifice de distribution commun unique. Le document CN2545134 décrit un distributeur de type duo comprenant deux poussoirs dépourvus d'orifice de distribution et un poussoir commun qui agit simultanément sur les deux poussoirs, mais qui ne définit pas d'orifice de distribution.  FR2793479 discloses a duo-type dispenser comprising two pushers without a dispensing orifice and a common pusher which acts simultaneously on the two pushers and which forms a single common dispensing orifice. The document CN2545134 describes a duo-type dispenser comprising two pushers without a dispensing orifice and a common push-button which acts simultaneously on the two pushers, but which does not define a dispensing orifice.
La présente invention a pour but de définir un autre type de distributeur duo à deux réservoirs et deux pompes, mais dont l'utilisation est plus simple pour l'utilisateur. En effet, l'utilisateur doit très simplement pouvoir distribuer uniquement le premier produit fluide ou le second produit fluide ou encore un mélange de ces deux produits fluides. Pour ce faire, la présente invention propose un distributeur de produit fluide comprenant deux réservoirs, deux pompes et deux poussoirs, à savoir un premier poussoir pour actionner une première pompe reliée à un premier réservoir contenant un premier produit fluide, et un deuxième poussoir pour actionner une deuxième pompe reliée à un deuxième réservoir contenant un deuxième produit fluide, le distributeur comprenant en outre un troisième poussoir pour distribuer un mélange des premier et deuxième produits fluides, le premier produit fluide étant distribué à travers un premier orifice de distribution, le deuxième produit fluide est distribué à travers un deuxième orifice de distribution, caractérisé en ce que le mélange des deux produits fluides est distribué à travers un troisième orifice de distribution formé par le troisième poussoir. The object of the present invention is to define another type of duo distributor with two tanks and two pumps, but whose use is simpler for the user. Indeed, the user must very simply be able to distribute only the first fluid product or the second fluid or a mixture of these two fluid products. To do this, the present invention provides a fluid dispenser comprising two tanks, two pumps and two pushers, namely a first pusher for actuating a first pump connected to a first reservoir containing a first fluid, and a second pusher for actuating a second pump connected to a second tank containing a second fluid, the dispenser further comprising a third pusher for dispensing a mixture of the first and second fluid products, the first fluid being dispensed through a first dispensing orifice, the second product fluid is dispensed through a second dispensing orifice, characterized in that the mixture of the two fluids is dispensed through a third dispensing orifice formed by the third pusher.
Lorsque l'utilisateur veut une dose du premier produit fluide il appuie sur le premier poussoir, lorsqu'il veut une dose du second produit fluide il appuie sur le second poussoir et lorsqu'il veut une dose combinée des premier et second produits fluides il appuie sur le troisième poussoir.  When the user wants a dose of the first fluid product he presses the first pusher, when he wants a dose of the second fluid he presses the second pusher and when he wants a combined dose of the first and second fluids he supports on the third pusher.
Selon un autre mode de réalisation avantageux, le troisième poussoir est monté sur une troisième pompe reliée aux premier et deuxième réservoirs. L'actionnement de ce troisième poussoir est donc totalement indépendant de l'actionnement des deux premiers poussoirs. Selon une forme de réalisation, un réservoir tampon de mélange est interposé entre la troisième pompe et les premier et deuxième réservoirs. Avantageusement, le réservoir tampon est relié aux premier et deuxième réservoirs par deux conduits équipés chacun d'un clapet anti-retour, les produits fluides étant aspirés par la troisième pompe dans le réservoir tampon à travers les conduits. Selon une autre forme de réalisation, la troisième pompe comprend deux tubes plongeurs s'étendant respectivement dans les premier et deuxième réservoirs. Dans les deux modes de réalisation, l'actionnement du troisième poussoir permet à la troisième pompe de prélever du produit fluide soit directement dans les deux premiers réservoirs soit indirectement à travers le réservoir tampon. Selon un autre aspect avantageux de la présente invention, les première et deuxième pompes définissent chacune un passage d'éventation interne qui est ouvert par actionnement des poussoirs, le troisième poussoir appuyant légèrement en fin de course sur les premier et deuxième poussoirs pour ouvrir les passages d'éventation internes des première et deuxième pompes. Avantageusement, le troisième poussoir comprend une collerette qui fait saillie vers l'extérieur au-dessus des premier et deuxième poussoirs, la distance axiale séparant la collerette des premier et deuxième poussoirs étant légèrement inférieure à la course du troisième poussoir. Ainsi, en actionnant le troisième poussoir, on évente les premier et second réservoirs. According to another advantageous embodiment, the third pusher is mounted on a third pump connected to the first and second tanks. The actuation of this third pusher is completely independent of the actuation of the first two pushers. According to one embodiment, a mixing buffer tank is interposed between the third pump and the first and second tanks. Advantageously, the buffer tank is connected to the first and second tanks by two conduits each equipped with a check valve, the fluid products being sucked by the third pump into the buffer tank through the conduits. According to another embodiment, the third pump comprises two plunger tubes respectively extending into the first and second reservoirs. In both embodiments, the actuation of the third pusher allows the third pump to take fluid either directly into the first two tanks or indirectly through the buffer tank. According to another advantageous aspect of the present invention, the first and second pumps each define an internal venting passage which is opened by actuation of the pushers, the third pushing button slightly pressing at the end of the race on the first and second pushers to open the passages. internal venting of the first and second pumps. Advantageously, the third pusher comprises a collar which protrudes outwardly above the first and second pushers, the axial distance separating the flange of the first and second pushers being slightly less than the stroke of the third pusher. Thus, by actuating the third pusher, fans the first and second tanks.
Un des principes de l'invention réside dans le fait de mettre en œuvre un troisième poussoir avec un troisième orifice de distribution qui permet de distribuer un mélange des produits fluides contenus dans les deux réservoirs. Le troisième poussoir peut agir directement sur les deux premiers poussoirs ou actionner une troisième pompe reliée directement ou indirectement aux deux réservoirs.  One of the principles of the invention lies in the fact of implementing a third pusher with a third dispensing orifice which allows to distribute a mixture of the fluid products contained in the two tanks. The third pusher can act directly on the first two pushers or actuate a third pump connected directly or indirectly to the two tanks.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints, donnant à titre d'exemples non limitatifs, trois modes de réalisation de l'invention.  The invention will now be further described with reference to the accompanying drawings, giving by way of non-limiting examples, three embodiments of the invention.
Sur les figures :  In the figures:
La figure 1 est une vue très schématique représentant un distributeur de l'art antérieur,  FIG. 1 is a very schematic view showing a distributor of the prior art,
Les figures 2 et 3 sont des vues très schématiques représentant respectivement deux modes de réalisation de la présente invention,  FIGS. 2 and 3 are very schematic views respectively representing two embodiments of the present invention,
La figure 4 est une vue plus détaillée du troisième mode de réalisation en position enfoncée du troisième poussoir, permettant ainsi l'éventation des deux premiers réservoirs, et  FIG. 4 is a more detailed view of the third embodiment in the depressed position of the third pusher, thus allowing the first two reservoirs to vent, and
La figure 5 est un vue agrandie du détail A de la figure 4 permettant de visualiser le cheminement de l'air d'éventation.  Figure 5 is an enlarged view of detail A of Figure 4 for viewing the path of the vent air.
Dans les trois modes de réalisation des figures 1 à 3, les distributeurs comprennent un premier réservoir R1 contenant un premier produit fluide F1 et un second réservoir R2 contenant un deuxième produit fluide F2. Les distributeurs comprennent également une première pompe P1 associée au premier réservoir R1 et une deuxième pompe P2 associée au deuxième réservoir R2. La première pompe P1 est pourvue d'un premier poussoir B1 et la deuxième pompe P2 est pourvue d'un deuxième poussoir B2. Les pompes P1 et P2 sont également pourvues de tubes plongeurs T1 , T2 qui s'étendent respectivement dans les réservoirs R1 et R2 pour acheminer du produit fluide aux pompes P1 , P2. Ainsi, lorsque l'utilisateur appuie sur le premier poussoir B1 , du produit fluide F1 issu du premier réservoir R1 est acheminé à travers le tube plongeur T1 la pompe P1 et jusqu'à un orifice de distribution. Il en est de même pour le poussoir B2 dont l'actionnement permet la distribution du deuxième produit fluide F2 au niveau de l'orifice de distribution. In the three embodiments of FIGS. 1 to 3, the distributors comprise a first reservoir R1 containing a first fluid product F1 and a second reservoir R2 containing a second fluid product F2. The distributors also include a first pump P1 associated with the first tank R1 and a second pump P2 associated with the second tank R2. The first pump P1 is provided with a first pusher B1 and the second pump P2 is provided with a second pusher B2. The pumps P1 and P2 are also provided with plunger tubes T1, T2 which respectively extend into the tanks R1 and R2 for conveying fluid to the pumps P1, P2. Thus, when the user presses the first pusher B1, fluid F1 from the first tank R1 is conveyed through the plunger tube T1 pump P1 and up to a dispensing orifice. It is the same for the B2 pusher whose actuation allows the distribution of the second fluid product F2 at the dispensing orifice.
Dans les trois modes de réalisation, le distributeur est pourvu d'un troisième poussoir B3 qui permet de distribuer un mélange des premier et deuxième produits fluides F1 , F2.  In all three embodiments, the dispenser is provided with a third pusher B3 which makes it possible to dispense a mixture of the first and second fluid products F1, F2.
Dans le premier mode de réalisation de la figure 1 qui représente l'art antérieur, le troisième poussoir T3 agit directement sur les premier et second poussoirs B1 , B2 de sorte qu'un mélange des deux produits fluides F1 , F2 est distribué au niveau de l'orifice de distribution O, qui est commun aux trois poussoirs B1 , B2, B3. Bien que non représenté, le distributeur du premier mode de réalisation pourrait intégrer trois orifices de distribution distincts pour les trois poussoirs respectivement. Il faut bien comprendre que l'actionnement du premier poussoir B1 laisse les deux autres poussoirs B2, B3 statiques. Il en est de même pour le deuxième poussoir B2. En revanche, lorsque l'on actionne le troisième poussoir B3, il entraîne avec lui les deux premiers poussoirs B1 , B2.  In the first embodiment of FIG. 1, which represents the prior art, the third pusher T3 acts directly on the first and second pushbuttons B1, B2 so that a mixture of the two fluid products F1, F2 is distributed at the level of FIG. the dispensing orifice O, which is common to the three pushers B1, B2, B3. Although not shown, the distributor of the first embodiment could integrate three separate dispensing ports for the three pushers respectively. It should be understood that the actuation of the first pusher B1 leaves the other two pushers B2, B3 static. It is the same for the second push B2. On the other hand, when the third pusher B3 is actuated, it carries with it the first two pushers B1, B2.
Dans le second mode de réalisation de l'invention de la figure 2, le troisième poussoir B3 est monté sur une troisième pompe P3 équipée d'un troisième tube plongeur T3 qui s'étend à l'intérieur d'un réservoir tampon de mélange R3, qui est distinct des réservoirs R1 et R2. Le réservoir tampon R3 est ensuite relié au premier réservoir R1 par un premier conduit C1 pourvu d'un clapet anti-retour V1 . De manière symétrique, le réservoir tampon R3 est également relié au deuxième réservoir R2 par un second conduit C2 équipé d'un clapet anti-retour V2. Les clapets V1 , V2 peuvent par exemple être montés sur les réservoirs R1 , R2 respectivement. Il faut encore noter que chaque poussoir B1 , B2 et B3 est pourvu d'un orifice de distribution propre 01 , 02 et 03. Ainsi, lorsque l'utilisateur veut distribuer une dose du premier produit fluide F1 , il appuie sur le premier poussoir B1 . De manière similaire, lorsqu'il veut distribuer une dose de produit F2 il appuie sur le deuxième poussoir B2. Et lorsqu'il veut distribuer un mélange des deux produits fluides F1 , F2 il appuie sur le troisième poussoir B3, qui actionne la pompe P3 qui va prélever un mélange de produit fluide déjà présent dans le réservoir tampon R3. Le mélange de produit fluide F1 + F2 présent dans le réservoir tampon R3 ne peut en aucun cas regagner les réservoirs R1 et R2 du fait de la présence des deux clapets anti-retour V1 , V2. En actionnant le poussoir B3, la pompe P3 puise le mélange de produit fluide F1 + F2 dans le réservoir R3 ce qui a pour effet d'aspirer du produit fluide F1 du réservoir R1 et du produit fluide F2 du réservoir R2 à travers les deux conduits C1 et C2, respectivement. In the second embodiment of the invention of FIG. 2, the third pusher B3 is mounted on a third pump P3 equipped with a third plunger tube T3 which extends inside a mixing buffer tank R3. , which is distinct from the tanks R1 and R2. The buffer tank R3 is then connected to the first tank R1 by a first pipe C1 provided with a non-return valve V1. In a symmetrical way, the buffer tank R3 is also connected to the second tank R2 by a second conduit C2 equipped with a non-return valve V2. The valves V1, V2 may for example be mounted on the tanks R1, R2 respectively. It should also be noted that each pusher B1, B2 and B3 is provided with a proper dispensing orifice 01, 02 and 03. Thus, when the user wants to dispense a dose of the first fluid product F1, he presses the first pusher B1 . Similarly, when he wants to dispense a dose of F2 product he presses the second push B2. And when he wants to distribute a mixture of the two fluid products F1, F2 he presses the third pusher B3, which actuates the pump P3 which will take a mixture of fluid already present in the buffer tank R3. The mixture of fluid product F1 + F2 present in the buffer tank R3 can not in any case regain the tanks R1 and R2 because of the presence of two check valves V1, V2. By actuating the pusher B3, the pump P3 draws the mixture of fluid product F1 + F2 into the tank R3, which has the effect of drawing fluid F1 from the tank R1 and the fluid product F2 from the tank R2 through the two ducts. C1 and C2, respectively.
Dans le troisième mode de réalisation de l'invention de la figure 3, le troisième poussoir B3 incorpore un orifice de distribution 03 et est monté sur une troisième pompe P3 équipée de deux tubes plongeurs, à savoir un tube plongeur T31 qui s'étend dans le premier réservoir R1 et un second tube plongeur T32 qui s'étend dans le deuxième réservoir R2. Le fonctionnement de ce distributeur est très simple : en appuyant sur le poussoir B1 ou B2, le distributeur distribue un seul produit fluide F1 ou F2, et en appuyant sur le poussoir B3, le distributeur distribue un mélange des deux produits fluides F1 , F2 à travers les tubes plongeurs T31 , T32 et la pompe P3.  In the third embodiment of the invention of FIG. 3, the third pusher B3 incorporates a dispensing orifice 03 and is mounted on a third pump P3 equipped with two plunger tubes, namely a dip tube T31 which extends into the first tank R1 and a second dip tube T32 which extends into the second tank R2. The operation of this dispenser is very simple: by pressing the pushbutton B1 or B2, the dispenser distributes a single fluid product F1 or F2, and pressing the pushbutton B3, the distributor distributes a mixture of the two fluid products F1, F2 to through the T31, T32 dip tubes and the P3 pump.
Selon un aspect particulièrement avantageux de l'invention, l'actionnement du troisième poussoir B3 peut engendrer l'éventation des deux réservoirs R1 , R2 à travers les passages d'éventation propres des pompes P1 , P2. Sur la figure 4, le poussoir B3 est représenté en position complètement enfoncée, et l'on peut voir qu'il comprend une collerette D3 qui vient en contact appuyé sur les poussoirs B1 et B2 de manière à les enfoncer légèrement. Cela est possible en disposant le troisième poussoir B3 de sorte que la distance d visible sur la figure 3 le séparant des deux autres poussoirs est légèrement inférieure à la course totale du poussoir B3. Ainsi, en fin de course du poussoir B3, la collerette D3 vient appuyer simultanément sur les deux autres poussoirs B1 , B2. Sur la figure 5, on voit un détail de la figure 4 qui laisse apparaître le passage d'éventation permettant à l'air extérieur de pénétrer à l'intérieur des réservoirs R1 et R2 lors de chaque actionnement, et notamment lors de l'actionnement du troisième poussoir B3. De manière tout à fait classique, le passage d'éventation est coupé en position de repos de la pompe par un piston coulissant à l'intérieur d'un fût de coulissement défini par les pompes. According to a particularly advantageous aspect of the invention, the actuation of the third pusher B3 can cause the two reservoirs R1, R2 to vent through the clean venting passages of the pumps P1, P2. In FIG. 4, the pusher B3 is shown in the fully depressed position, and it can be seen that it comprises a flange D3 which comes into pressed contact with the pushbuttons B1 and B2 so as to push lightly. This is possible by arranging the third pusher B3 so that the distance d visible in Figure 3 separating it from the other two pushers is slightly less than the total stroke of the pusher B3. Thus, at the end of the stroke of the pusher B3, the flange D3 comes to simultaneously press the two other pushers B1, B2. In Figure 5, we see a detail of Figure 4 which reveals the venting passage allowing the outside air to enter the tanks R1 and R2 during each actuation, especially during actuation of the third pusher B3. In a completely conventional manner, the venting passage is cut in the rest position of the pump by a piston sliding inside a sliding shaft defined by the pumps.
Grâce à l'invention, on dispose d'un distributeur de type duo, mais comprenant trois poussoirs distincts avec trois orifices de distribution respectifs, permettant respectivement de distribuer le premier produit fluide, le deuxième produit fluide ou un mélange des deux produits fluides.  Thanks to the invention, there is a duo-type dispenser, but comprising three separate pushers with three respective dispensing orifices, respectively for dispensing the first fluid, the second fluid or a mixture of the two fluids.
