Abstract

The invention relates to a fluid product dispenser. The inventive dispenser consists of: a first fluid product dispensing element (1) which is associated with a first fluid product container (15), said first element comprising a first actuating rod (11) which can move along a first rod axis between a rest position and an actuated position; and a second fluid product dispensing element (2) which is associated with a second fluid product container (25), said second element comprising a second actuating rod (21) which can move along a second rod axis between a rest position and an actuated position. Moreover, the first rod (11) comprises a free end (111) which faces in a first direction and the second rod (21) comprises a second free end (211) which faces in a second direction. The two dispensing elements are disposed in relation to one another such that the first and second rod axes extend in parallel, but the first and second free ends are facing in opposite directions. In this way, one of said dispensing elements is disposed backwards in relation to the other element. The invention is characterised in that air is not recirculated into at least one of the containers, such that the volume of said container reduces as the fluid product is extracted therefrom.

Description

Distributeur de produit fluide Fluid dispenser
La présente invention concerne un distributeur de produit fluide comprenant deux organes de distribution de produits fluides, liquides ou pulvérulents, tels que des pompes ou des valves. Chaque organe de distribution est associé à un réservoir respectif contenant du produit fluide. Les produits fluides des deux réservoirs peuvent être de nature identique ou différente. Ce genre de distributeur est souvent désigné sous le terme de « duo » dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie.The present invention relates to a fluid dispenser comprising two organs for dispensing fluid, liquid or pulverulent products, such as pumps or valves. Each dispensing member is associated with a respective reservoir containing fluid. The fluid products of the two tanks can be identical or different in nature. This type of distributor is often referred to as a "duo" in the fields of perfumery, cosmetics or even pharmacy.
De manière conventionnelle, ces distributeurs de type duo sont agencés de telle sorte que les réservoirs sont disposés côte à côte. Lorsque le distributeur est maintenu en position debout, les fonds des réservoirs sont situés en bas et les organes de distribution (pompes) sont disposés au sommet des réservoirs. En général, une tête de distribution commune vient coiffer les deux organes de distribution. Chaque organe de distribution comprend en général un corps à l'intérieur duquel une tige d'actionnement est déplaçable axialement entre une position de repos et une position actionnée. La tige d'actionnement comprend une extrémité libre qui pointe vers le haut. Dans un distributeur duo classique, les deux tiges d'actionnement pointent vers le haut. La tête de distribution est rapportée et fixée sur les extrémités libres des tiges d'actionnement. La tête d'actionnement forme également un ou deux orifice(s) de distribution. En résumé, un distributeur duo se constitue une juxtaposition de deux distributeurs classiques constitués d'un réservoir et d'un organe de distribution auxquels est associée une tête de distribution commune formant la sortie de distribution.Conventionally, these duo type distributors are arranged so that the tanks are arranged side by side. When the dispenser is kept in a standing position, the bottoms of the tanks are located at the bottom and the distribution members (pumps) are arranged at the top of the tanks. In general, a common dispensing head covers the two dispensing members. Each dispensing member generally comprises a body inside which an actuating rod is axially movable between a rest position and an actuated position. The actuating rod has a free end which points upwards. In a classic duo dispenser, the two actuating rods point upwards. The dispensing head is attached and fixed to the free ends of the actuating rods. The actuating head also forms one or two dispensing orifice (s). In summary, a dual dispenser is a juxtaposition of two conventional dispensers consisting of a reservoir and a dispensing member with which is associated a common dispensing head forming the dispensing outlet.
Ce genre de distributeur duo présente plusieurs désavantages. Premièrement, du fait que les réservoirs sont disposés côté à côté, cela augmente considérablement et obligatoirement la section du distributeur. Très souvent, les distributeurs duo présentent un aspect trapu avec une tête de distribution imposante. Ensuite, la force d'appui qu'il est nécessaire d'appliquer sur la tête de distribution commune doit être supérieure à la somme ou au cumul des forces qu'il faut appliquer sur chaque tige d'actionnement. Il en résulte que les distributeurs duo sont assez difficiles à actionner du fait qu'ils présentent une très grande résistance à l'actionnement. Si l'on réalise un distributeur duo à l'aide de pompe standard ayant une force d'actionnement standard, on obtient une force d'appui doublée pour la tête de distribution du distributeur duo. Un but de l'invention est de remédier aux inconvénients précités de l'art antérieur en définissant un distributeur du type duo présentant une configuration différente et dont la force d'actionnement ou d'appui peut être maintenue à un niveau convenable et agréable tout en utilisant des organes de distribution standards. On connaît du document US-3 451 593 un distributeur duo comprenant deux bidons aérosols munis de valves et contenant un produit fluide sous pression. Les bidons sont disposés l'un au-dessus de l'autre avec les valves se faisant face. Le distributeur comprend en outre une tête de distribution commune à laquelle sont connectées les deux valves. En appuyant sur le fond du bidon disposé à l'envers, on actionne les deux valves simultanément. Les produits fluides des deux bidons sont alors refoulés vers la tête de distribution où ils sont mélangés avant d'être distribués.This kind of duo distributor has several disadvantages. Firstly, because the tanks are arranged side by side, this considerably increases and necessarily the section of the distributor. Very often, duo dispensers have a stocky appearance with an imposing dispensing head. Then, the bearing force which it is necessary to apply to the common dispensing head must be greater than the sum or the sum of the forces which must be applied to each actuating rod. As a result, the Duo dispensers are quite difficult to actuate because they have a very high resistance to actuation. If a duo dispenser is produced using a standard pump having a standard actuating force, a double pressing force is obtained for the dispensing head of the duo dispenser. An object of the invention is to remedy the aforementioned drawbacks of the prior art by defining a dispenser of the duo type having a different configuration and whose actuation or support force can be maintained at a suitable and pleasant level while using standard distribution devices. Document US-3,451,593 discloses a dual dispenser comprising two aerosol cans provided with valves and containing a fluid product under pressure. The cans are arranged one above the other with the valves facing each other. The dispenser further includes a common dispensing head to which the two valves are connected. By pressing the bottom of the container arranged upside down, the two valves are actuated simultaneously. The fluid products from the two cans are then discharged to the dispensing head where they are mixed before being dispensed.
Le bidon disposé à l'endroit est pourvu d'un tube-plongeur, alors que le distributeur disposé à l'envers en est dépourvu. Si l'utilisateur utilise ce distributeur à l'envers ou incliné, la distribution simultanée des deux distributeurs n'est plus assurée.The container placed at the front is provided with a dip tube, while the distributor arranged upside down is devoid of it. If the user uses this distributor upside down or inclined, the simultaneous distribution of the two distributors is no longer ensured.
De plus, les produits fluides sont au contact des gaz propulseurs dans les bidons sous pression.In addition, the fluids are in contact with the propellants in the pressurized containers.
Le but de la présente invention est de remédier aux inconvénients du distributeur de l'art antérieur susmentionné.The object of the present invention is to remedy the drawbacks of the dispenser of the above-mentioned prior art.
Pour atteindre ces buts, la présente invention propose un distributeur de produit fluide comprenant un premier organe de distribution de produit fluide associé à un premier réservoir de produit fluide, ledit premier organe comprenant une première tige d'actionnement déplaçable selon un premier axe de tige entre une position de repos et une position actionnée, et un second organe de distribution de produit fluide associé à un second réservoir de produit fluide, ledit second organe comprenant une seconde tige d'actionnement déplaçable selon un second axe de tige entre une position de repos et une position actionnée, la première tige comprenant une extrémité libre pointant dans une première direction et la seconde tige ayant une seconde extrémité libre pointant dans une seconde direction, les deux organes étant disposés l'un par rapport à l'autre avec les premier et second axes de tige s'étendant parallèlement et avec la première direction opposée à la seconde direction de sorte qu'un organe de distribution est disposé à l'envers par rapport à l'autre organe de distribution, caractérisé en ce que au moins un des réservoirs est sans reprise d'air, son volume diminuant à mesure que du produit fluide en est extrait. .To achieve these goals, the present invention provides a fluid dispenser comprising a first fluid dispenser member associated with a first fluid reservoir, said first member comprising a first actuating rod movable along a first rod axis between a rest position and an actuated position, and a second fluid dispenser member associated with a second fluid reservoir, said second member comprising a second actuating rod movable along a second rod axis between a rest position and an actuated position, the first rod comprising a free end pointing in a first direction and the second rod having a second free end pointing in a second direction, the two members being arranged relative to each other with the first and second rod axes extending parallel and with the first direction opposite to the second direction so that a distribution member is arranged upside down with respect to the other dispensing member, characterized in that at least one of the reservoirs is without air intake, its volume decreasing as fluid is extracted from it. .
Avantageusement, les deux axes de tige sont confondus. Ainsi, la présente invention propose de disposer les deux organes de distribution l'un au-dessus de l'autre avec leur tige d'actionnement pointant l'une vers l'autre. Un organe de distribution est alors à l'endroit, et l'autre organe de distribution est à l'envers. Les réservoirs peuvent ainsi être disposés l'un au-dessus de l'autre, et non plus côte à côte comme c'est le cas dans l'art antérieur. Le distributeur peut alors présenter un aspect allongé ou longiligne qui est plus esthétique que l'aspect trapu de l'art antérieur. En outre, la force d'appui nécessaire pour actionner le distributeur est seulement égale à la force d'appui la plus grande d'un des deux organes de distribution. En effet, dans cette configuration superposée, les forces d'appui ne s'additionnent pas comme c'est le cas avec la disposition juxtaposée de l'art antérieur. De ce fait, la force d'appui nécessaire pour actionner le distributeur selon l'invention est bien plus faible, puisque seulement égale à la force d'appui de l'organe de distribution le plus dur à actionner. Selon un mode de réalisation avantageux, les organes de distribution sont des pompes. Avantageusement, au moins un des réservoirs est choisi dans le groupe formé des réservoirs à piston-suiveur et des poches souples de volume variable.Advantageously, the two rod axes are combined. Thus, the present invention proposes to arrange the two distribution members one above the other with their actuating rod pointing towards one another. One dispenser is then upside down, and the other dispenser is upside down. The reservoirs can thus be arranged one above the other, and no longer side by side as is the case in the prior art. The dispenser can then have an elongated or elongated appearance which is more aesthetic than the stocky appearance of the prior art. In addition, the support force required to actuate the dispenser is only equal to the greater support force of one of the two dispensing members. Indeed, in this superimposed configuration, the support forces do not add up as is the case with the juxtaposed arrangement of the prior art. Therefore, the support force necessary to actuate the dispenser according to the invention is much lower, since only equal to the support force of the hardest dispensing member to actuate. According to an advantageous embodiment, the distribution members are pumps. Advantageously, at least one of the tanks is chosen from the group formed by piston-follower tanks and flexible bags of variable volume.
Selon une forme de réalisation, le distributeur comprend un poussoir déplaçable selon un axe de poussée s'étendant parallèlement aux axes de tiges, ledit poussoir, lorsque soumis à une force de poussée, sollicitant une extrémité libre de tige vers l'autre extrémité de tige. Avantageusement, ledit poussoir agit sur un réservoir pour le déplacer vers l'autre réservoir, les tiges d'actionnement des deux organes de distribution restant statiques l'une par rapport à l'autre tout en se déplaçant ensemble vers les réservoirs. Selon une forme de réalisation, le poussoir forme un logement de réception pour un réservoir de produit fluide.According to one embodiment, the dispenser comprises a pusher movable along a thrust axis extending parallel to the rod axes, said pusher, when subjected to a thrust force, urging one end rod free to the other rod end. Advantageously, said pusher acts on a reservoir to move it towards the other reservoir, the actuating rods of the two dispensing members remaining static with respect to each other while moving together towards the reservoirs. According to one embodiment, the pusher forms a receiving housing for a fluid reservoir.
Avantageusement, le poussoir comprend des moyens de guidage axial pour assurer le déplacement axial du réservoir qu'il sollicite. De préférence, un réservoir est reçu dans une coque, une tête de distribution commune aux deux organes de distribution étant coulissante axialement dans la coque, ledit poussoir étant coulissant axialement dans la coque.Advantageously, the pusher comprises axial guide means for ensuring the axial displacement of the reservoir which it requests. Preferably, a reservoir is received in a hull, a dispensing head common to the two dispensing members being sliding axially in the hull, said pusher being sliding axially in the hull.
Selon une forme de réalisation pratique, le distributeur de produit fluide comprend une tête de distribution pourvue d'au moins un conduit de sortie débouchant au niveau d'au moins un orifice de distribution, ladite tête comprenant deux manchons de raccordement communiquant avec ledit au moins un conduit de sortie et recevant chacun une extrémité libre d'une tige d'actionnement, les deux manchons étant solidaires en déplacement l'un de l'autre. Avantageusement, la tête forme des moyens de guidage pour un organe de distribution.According to a practical embodiment, the fluid dispenser comprises a dispensing head provided with at least one outlet duct opening at at least one dispensing orifice, said head comprising two connection sleeves communicating with said at least an outlet conduit and each receiving a free end of an actuating rod, the two sleeves being integral in displacement with one another. Advantageously, the head forms guide means for a dispensing member.
Selon un autre aspect de l'invention, un organe de distribution est situé au-dessus de son réservoir et l'autre organe de distribution est situé en dessous de son réservoir, l'organe de distribution situé en dessous du réservoir étant pourvu d'un tube d'éventation qui s'étend dans le réservoir hors du produit fluide. En variante, au moins un des réservoirs est sans reprise d'air, son volume diminuant à mesure que du produit fluide en est extrait. L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif deux modes de réalisation de l'invention.According to another aspect of the invention, a dispensing member is located above its reservoir and the other dispensing member is located below its reservoir, the dispensing member located below the reservoir being provided with a vent tube which extends into the reservoir outside the fluid product. As a variant, at least one of the reservoirs has no air intake, its volume decreasing as the fluid product is extracted therefrom. The invention will now be described more fully with reference to the accompanying drawings which give two embodiments of the invention by way of non-limiting example.
Sur les figures :In the figures:
- la figure 1 est une vue en coupe transversale verticale à travers un distributeur de produit fluide selon un premier mode de réalisation de rinvention en position de repos, - la figure 2 est une vue du distributeur de la figure 1 en position actionnée, etFIG. 1 is a vertical cross-section view through a fluid dispenser according to a first embodiment of the invention in the rest position, FIG. 2 is a view of the dispenser of FIG. 1 in the actuated position, and
- la figure 3 est une vue en section transversale verticale à travers un distributeur de produit fluide selon un second mode de réalisation de l'invention en position de repos.- Figure 3 is a vertical cross-sectional view through a fluid dispenser according to a second embodiment of the invention in the rest position.
Dans les deux modes de réalisation utilisés pour illustrer la présente invention, le distributeur de produit fluide de l'invention est un distributeur duo comprenant deux réservoirs 15, 25, deux organes de distribution, en l'occurrence des pompes 1, 2 et une tête de distribution commune 5. Des valves peuvent très bien être utilisées à la place des pompes, les valves étant plus adaptés à la distribution de poudres sèches ou en suspension.In the two embodiments used to illustrate the present invention, the fluid dispenser of the invention is a duo dispenser comprising two reservoirs 15, 25, two dispensing members, in this case pumps 1, 2 and a head common dispensing 5. Valves may very well be used in place of pumps, the valves being more suitable for dispensing dry or suspended powders.
Selon l'invention, lorsque le distributeur est maintenu dans une position debout, qui est une position de repos d'appui sur une surface plane, mais également une position d'utilisation normale et logique, une pompe, en l'occurrence la pompe 1, est placée ou disposée en dessous de la pompe 2. Ainsi, la pompe 1 sera dénommée pompe inférieure et la pompe 2 sera dénommée pompe supérieure.According to the invention, when the dispenser is held in a standing position, which is a resting position for resting on a flat surface, but also a position for normal and logical use, a pump, in this case the pump 1 , is placed or arranged below the pump 2. Thus, the pump 1 will be called the lower pump and the pump 2 will be called the upper pump.
Il en est de même avec les réservoirs 15 et 25. Le réservoir 15 est le réservoir inférieur associé à la pompe inférieure 1 et le réservoir 25 est le réservoir supérieur associé à la pompe supérieure 2. Dans les modes de réalisation des figures, le réservoir 15 est situé en dessous de la pompe 1 et le réservoir 25 est situé au-dessus de la pompe 2.It is the same with the reservoirs 15 and 25. The reservoir 15 is the lower reservoir associated with the lower pump 1 and the reservoir 25 is the upper reservoir associated with the upper pump 2. In the embodiments of the figures, the reservoir 15 is located below the pump 1 and the reservoir 25 is located above the pump 2.
Selon l'invention, la tête de distribution commune 5 est disposée entre les pompes 1 et 2. Une autre disposition des réservoirs par rapport aux pompes est possible en restant dans le cadre de l'invention en maintenant toutefois comme caractéristique avantageuse qu'une pompe en l'occurrence la pompe 2 est située au-dessus de la pompe inférieure 1.According to the invention, the common dispensing head 5 is disposed between the pumps 1 and 2. Another arrangement of the reservoirs with respect to the pumps is possible while remaining within the scope of the invention, however maintaining as an advantageous characteristic that a pump in this case the pump 2 is located above the lower pump 1.
Selon l'invention, la pompe inférieure 1 comprend un corps 12 et une tige d'actionnement 11 qui est déplaçable axialement le long d'un axe de tige X-X.According to the invention, the lower pump 1 comprises a body 12 and an actuating rod 11 which is axially movable along a rod axis X-X.
De manière symétrique, la pompe supérieure 2 comprend un corps de pompe 22 et une tige d'actionnement 21 déplaçable axialement selon le même axe de tige X-X. Ainsi, les deux tiges 11 et 21 sont disposées de manière alignée sur un axe de tige commun X-X. On peut toutefois prévoir que les axes des tiges 11 et 21 ne soient pas confondus, mais juste parallèles. L'alignement des axes de tiges est une forme de réalisation préférée.Symmetrically, the upper pump 2 comprises a pump body 22 and an actuating rod 21 movable axially along the same rod axis XX. Thus, the two rods 11 and 21 are arranged in an aligned manner on a common rod axis XX. It can however be provided that the axes of the rods 11 and 21 are not merged, but just parallel. Alignment of the rod axes is a preferred embodiment.
La tige 11 de la pompe inférieure 1 comprend une extrémité libre 111 qui pointe vers le haut sur les figures. De manière symétrique, la tige d'actionnement 21 de la pompe supérieure 2 comprend une extrémité libre 211 qui pointe vers le bas. Lorsque les axes de tiges des deux tiges sont confondus comme c'est le cas sur les figures, rextrémité libre 111 de la tige 11 pointe vers extrémité libre 211 de la tige 21. Plus généralement, on peut dire que la pompe inférieure 1 est disposée à l'endroit, alors que la pompe supérieure 2 est disposée à l'envers.The rod 11 of the lower pump 1 comprises a free end 111 which points upwards in the figures. Symmetrically, the actuating rod 21 of the upper pump 2 comprises a free end 211 which points downwards. When the rod axes of the two rods are merged as is the case in the figures, free end 111 of rod 11 points towards free end 211 of rod 21. More generally, it can be said that the lower pump 1 is arranged upright, while the upper pump 2 is arranged upside down.
Les extrémités libres 111 et 211 des tiges 11 et 21 sont connectées à la tête de distribution commune 5. Dans les deux formes de réalisation de l'invention représentées sur les figures, les tiges d'actionnement 111 et 211 défimssent intérieurement un conduit de sortie de produit fluide par lequel le produit fluide pressurisé à l'intérieur des pompes est refoulé lors de leur actionnement. La tête de distribution commune 5 comprend un ou deux canaux de distribution débouchant au niveau d'un ou de deux orifices de distribution respectifs 510, 520. Sur les différentes figures, la tête de distribution 5 comprend deux canaux de distribution distincts 51 et 52 connectés respectivement aux extrémités libres 111 et 211 des tiges d'actionnement respectives 11 et 21. Ainsi, le produit fluide refoulé à travers la tige d'actionnement 11 peut ensuite s'écouler à travers le canal de distribution 51 pour déboucher au niveau de l'orifice de distribution 510. De manière symétrique, le produit refoulé à travers la tige d'actionnementThe free ends 111 and 211 of the rods 11 and 21 are connected to the common dispensing head 5. In the two embodiments of the invention shown in the figures, the actuating rods 111 and 211 internally define an outlet conduit fluid product by which the pressurized fluid product inside the pumps is discharged when they are actuated. The common distribution head 5 comprises one or two distribution channels opening out at one or two respective distribution orifices 510, 520. In the various figures, the distribution head 5 comprises two separate distribution channels 51 and 52 connected respectively at the free ends 111 and 211 of the respective actuating rods 11 and 21. Thus, the fluid product discharged through the actuating rod 11 can then flow through the distribution channel 51 to open at the dispensing orifice 510. Symmetrically, the product discharged through the actuating rod
21 peut s'écouler à travers le canal de distribution 52 et déboucher au niveau de l'orifice de distribution 520. Dans la forme de réalisation particulière, le canal 52 s'étend de manière centrale axiale alors que le conduit 51 s'étend de manière concentrique autour du canal 52. L'orifice de distribution 510 se présente ainsi sous la forme d'un annulaire entourant l'orifice de distribution central 520. Il ne s'agit là que d'une forme de réalisation particulière. Les deux canaux 51 et 52 peuvent également s'étendre de manière adjacente et déboucher au niveau de deux orifices de distribution disposés côte à côte.21 can flow through the distribution channel 52 and open at the distribution orifice 520. In the particular embodiment, the channel 52 extends centrally axially while the conduit 51 extends from concentrically around the channel 52. The dispensing orifice 510 is thus in the form of an annular surrounding the central dispensing orifice 520. This is only a particular embodiment. The two channels 51 and 52 can also extend adjacent to each other and lead to two distribution orifices arranged side by side.
Une autre caractéristique commune aux deux modes de réalisation représentée sur les figures réside dans le fait que le distributeur comprend une coque extérieure 4, de préférence réalisée en un matériau sensiblement rigide.Another characteristic common to the two embodiments shown in the figures lies in the fact that the dispenser comprises an outer shell 4, preferably made of a substantially rigid material.
Cette coque 4 contient avantageusement le réservoir inférieur 15, la pompe inférieure 1, la tête de distribution commune 5, la pompe supérieure 2 et optionnellement ou partiellement le réservoir supérieur 25. La coque 4 comprend un fond fermé 42 à partir duquel s'élève un fût sensiblement cylindrique 4L Le fût 41 peut comprendre une ouverture 44 à travers laquelle passent les canaux de distribution 51, 52 de sorte que leurs orifices de distribution respectifs s'étendent hors de la coque. La coque 4 peut servir de moyen de maintien ou de stabilisation du réservoir 15, de la pompe inférieure 1, ainsi que de moyens de guidage pour la tête de distribution commune 5, la pompe supérieure 2 et éventuellement le réservoir supérieur 25. La structure détaillée de ces différents moyens sera décrite ci-après en référence aux figures.This shell 4 advantageously contains the lower reservoir 15, the lower pump 1, the common dispensing head 5, the upper pump 2 and optionally or partially the upper reservoir 25. The shell 4 comprises a closed bottom 42 from which rises a substantially cylindrical barrel 4L The barrel 41 may include an opening 44 through which the distribution channels 51, 52 pass so that their respective distribution orifices extend out of the shell. The shell 4 can serve as a means of holding or stabilizing the reservoir 15, of the lower pump 1, as well as of guiding means for the common dispensing head 5, the upper pump 2 and possibly the upper reservoir 25. The detailed structure of these different means will be described below with reference to the figures.
Dans les deux modes de réalisation, le distributeur comprend un poussoir 3 ou 231. Ce poussoir est accessible à partir de l'extrémité supérieure ouverte de la coque 4. La coque 4 peut se présenter sous la forme d'un tube de section circulaire ou autre dont le fond 42 est fermé et dont l'extrémité supérieure est ouverte. Le poussoir 3 ; 231 permet d'exercer une force dans la direction de l'axe de tige commun X-X. Dans les deux formes de réalisation des figures, le poussoir agit sur le réservoir supérieur 25, et la force est ainsi transmise à la pompe supérieure 2, à la tête de distribution commune 5, à la pompe inférieure 1, puis sur le réservoir 15 et enfin sur le fond 42 de la coque 4. L'utilisateur peut par exemple maintenir le distributeur à l'aide d'une main en le saisissant par le fut 41 de la coque 4 et appuyer sur le poussoir 3 ; 231 à l'aide d'un doigt de cette même main, par exemple l'index. Il s'agit là d'un geste tout à fait naturel pour l'actionnement d'un distributeur. L'enfoncement du poussoir engendre un déplacement axial de la pompe supérieure 2, de la tête de distribution communeIn the two embodiments, the dispenser comprises a pusher 3 or 231. This pusher is accessible from the open upper end of the shell 4. The shell 4 can be in the form of a tube of circular cross section or another whose bottom 42 is closed and whose upper end is open. Pusher 3; 231 allows to exert a force in the direction of the common rod axis X-X. In the two embodiments of the figures, the pusher acts on the upper reservoir 25, and the force is thus transmitted to the upper pump 2, to the common dispensing head 5, to the lower pump 1, then to the reservoir 15 and finally on the bottom 42 of the shell 4. The user can for example hold the dispenser with one hand by grasping it by the barrel 41 of the shell 4 and pressing the pusher 3; 231 using a finger of this same hand, for example the index finger. This is a completely natural gesture for the actuation of a distributor. Pressing the plunger generates an axial displacement of the upper pump 2, of the common dispensing head
5 et de la tige d'actionnement 11 de la pompe inférieure 1, par rapport à la coque 4 dans une direction s'étendant dans l'axe commun de tige X-X. Plus précisément, lorsque l'on appuie sur le poussoir 3 ; 231, le réservoir supérieur 25 est entraîné vers le bas avec le corps 22 de la pompe supérieure 2. Dans les formes de réalisation particulières représentées sur les dessins, le sous-ensemble constitué par le poussoir, le réservoir supérieur 25 et le corps 22 de la pompe supérieure 2 se déplace unitairement. D'autre part, le corps 12 de la pompe inférieure 1 et le réservoir inférieur 15 sont statiques par rapport à la coque 4. us forment de ce fait un second sous-ensemble statique inférieur. Lorsque le sous- ensemble supérieur se déplace vers le sous-ensemble inférieur, ceci a pour effet d'enfoncer la tige d'actionnement 21 à l'intérieur du corps 22 de la pompe supérieure 2 et d'enfoncer la tige d'actionnement 11 de la pompe inférieure 1 dans le corps 12. Etant donné que la tête de distribution 5 est connectée entre les deux tiges, celle-ci se déplace également. Dans les modes de réalisation des figures, on peut dire que la tige d'actionnement 21 se déplace vers le réservoir 25 et la tige d'actionnement 11 se déplacer vers le réservoir 15. La tête de distribution commune 5 se déplace à la fois vers le réservoir 25 et le réservoir 15 en se déplaçant en même temps vers le bas par rapport à la coque 4.5 and the actuating rod 11 of the lower pump 1, relative to the shell 4 in a direction extending in the common axis of rod XX. More precisely, when the pusher 3 is pressed; 231, the upper reservoir 25 is driven downwards with the body 22 of the upper pump 2. In the particular embodiments shown in the drawings, the subassembly consisting of the pusher, the upper reservoir 25 and the body 22 of the upper pump 2 moves unitarily. On the other hand, the body 12 of the lower pump 1 and the lower reservoir 15 are static with respect to the shell 4. They therefore form a second lower static sub-assembly. When the upper sub-assembly moves towards the lower sub-assembly, this has the effect of driving the actuating rod 21 inside the body 22 of the upper pump 2 and of driving the actuating rod 11 of the lower pump 1 in the body 12. Since the dispensing head 5 is connected between the two rods, the latter also moves. In the embodiments of the figures, it can be said that the actuating rod 21 moves towards the reservoir 25 and the actuating rod 11 moves towards the reservoir 15. The common dispensing head 5 moves at the same time the reservoir 25 and the reservoir 15 while moving downward at the same time relative to the shell 4.
Avec cette disposition particulière des pompes 1 et 2, en l'occurrence de manière superposée avec la pompe supérieure disposée à l'envers, la force d'appui nécessaire pour enfoncer le poussoir est seulement égale à la force d'actionnement de la pompe la plus dure à actionner. Si les deux pompes ont la même charge ou résistance d'actionnement, la force d'appui sur le poussoir est seulement égale à la charge d'une pompe, et non pas à la somme des charges des deux pompes, comme c'est le cas lorsque les deux pompes sont disposées de manière côte à côte avec leur tige d'actionnement pointant dans le même sens.With this particular arrangement of pumps 1 and 2, in this case superimposed with the upper pump arranged upside down, the pressing force necessary to depress the pusher is only equal to the actuating force of the pump. harder to operate. If the two pumps have the same load or actuating resistance, the pressing force on the pusher is only equal to the load of one pump, and not to the sum of the loads of the two pumps, as is the case when the two pumps are arranged side by side with their actuating rod pointing in the same direction.
On réduit ainsi considérablement la force d'appui nécessaire pour l' actionnement du distributeur. De plus, le distributeur peut avoir un aspect esthétique allongé, et non plus trapu comme avec les distributeurs duo de l'art antérieur dans lesquels les deux réservoirs étaient disposés côte à côte. On se référera maintenant aux figures 1 et 2 pour expliquer de manière plus approfondie le premier mode de réalisation de l'invention. Le réservoir inférieur 15 est défini par un récipient 16 qui est rigide ou semi-rigide. Le récipient 16 comprend un fond 17 qui peut venir en appui sur le fond 42 de la coque 4. Le diamètre extérieur du récipient 16 peut être choisi de manière à pouvoir être inséré sensiblement sans jeu à l'intérieur du fût 41 de la coque 4. Ainsi, le récipient 16 est parfaitement maintenu à l'intérieur de la coque 4 au niveau de son fond 17 mais également au niveau de sa paroi latérale. Le récipient 16 comprend à son extrémité opposée au fond 17 un col 18 qui définit une ouverture faisant communiquer le réservoir 15 avec l'extérieur. La pompe 1 est disposée partiellement dans l'ouverture formée par le col 18. Le corps 12 comprend une collerette de fixation 17 en appui sur le bord d'extrémité supérieure du col 18. Une bague de fixation 6 est utilisée pour maintenir la collerette 13 sur le col 18. La bague 6 est ici une bague d'encliquetage venant coopérer avec l'extérieur du col 18. La bague 6 comprend également une couronne extérieure qui vient en prise avec la paroi interne du fût 41 de la coque 4 pour maintenir fixement la pompe 1 ainsi que le récipient 16 à l'intérieur de la coque 4. Etant donné que le récipient 16 est rigide ou semi-rigide, la pompe 1 est pourvue d'un tube plongeur 14 qui s'étend dans le réservoir 15 jusqu'au niveau du fond 17. En position debout, le niveau NI du produit fluide à l'intérieur du réservoir 15, lorsque celui-ci est rempli, se situe au niveau ou juste en dessous du col 18.This considerably reduces the contact force necessary for actuating the dispenser. In addition, the dispenser can have an elongated aesthetic appearance, and no longer chunky as with the dual dispensers of the prior art in which the two tanks were arranged side by side. Reference will now be made to FIGS. 1 and 2 to explain in more detail the first embodiment of the invention. The reservoir lower 15 is defined by a container 16 which is rigid or semi-rigid. The container 16 comprises a bottom 17 which can come to bear on the bottom 42 of the shell 4. The outside diameter of the container 16 can be chosen so that it can be inserted substantially without play inside the barrel 41 of the shell 4 Thus, the container 16 is perfectly maintained inside the shell 4 at its bottom 17 but also at its side wall. The container 16 comprises at its end opposite the bottom 17 a neck 18 which defines an opening communicating the tank 15 with the outside. The pump 1 is partially disposed in the opening formed by the neck 18. The body 12 comprises a fixing flange 17 bearing on the upper end edge of the neck 18. A fixing ring 6 is used to hold the flange 13 on the neck 18. The ring 6 is here a snap ring coming to cooperate with the outside of the neck 18. The ring 6 also includes an outer ring which engages with the internal wall of the barrel 41 of the shell 4 to maintain fixedly the pump 1 as well as the container 16 inside the shell 4. Since the container 16 is rigid or semi-rigid, the pump 1 is provided with a dip tube 14 which extends into the reservoir 15 up to the level of the bottom 17. In the standing position, the level NI of the fluid inside the reservoir 15, when the latter is filled, is located at or just below the neck 18.
Le réservoir supérieur 15 est formé par un récipient rigide ou semi-rigide 26 définissant un col 28 dans lequel la pompe 2 est fixée au moyen d'un système de fixation quelconque. Une bague de fixation classique peut par exemple être utilisée. Le récipient 26 comprend un fond 27 orienté vers le haut. Le niveau N2 du produit fluide à l'intérieur du réservoir 25, lorsque celui-ci est rempli, est situé sensiblement au niveau du fond 27. Etant donné que le récipient 26 est rigide, et de ce fait sensiblement indéformable, il est nécessaire de compenser le volume de produit fluide extrait du réservoir par un volume sensiblement correspondant d'air. Pour ce faire, la pompe supérieure 2 est pourvue d'un tube d'éventation 24 qui s'étend dans le réservoir 25 sensiblement jusqu'au niveau du fond supérieurThe upper reservoir 15 is formed by a rigid or semi-rigid container 26 defining a neck 28 in which the pump 2 is fixed by means of any fixing system. A conventional fixing ring can for example be used. The container 26 comprises a bottom 27 oriented upwards. The level N2 of the fluid inside the reservoir 25, when the latter is filled, is situated substantially at the level of the bottom 27. Since the container 26 is rigid, and therefore substantially non-deformable, it is necessary to compensate for the volume of fluid extracted from the reservoir with a substantially corresponding volume of air. To do this, the upper pump 2 is provided with a vent tube 24 which extends in the tank 25 substantially up to the level of the upper bottom.
27. Le récipient 26 est ici associé à un poussoir 3 comprenant une surface supérieure d'appui 31 sur la périphérie de laquelle s'étend vers le bas une jupe de guidage 32. Cette jupe 32 forme également en association avec une bride 33 un logement 34 à l'intérieur duquel le récipient 26 est reçu de manière fixe et stable. Le fond 27 vient en contact de la surface d'appui 31. La jupe de guidage périphérique 32 est adaptée à coulisser sans étanchéité à l'intérieur de la coque 4. Plus précisément, la coque 4 définit une avancée de guidage 43 située juste au- dessus des orifices de distribution 510, 520. La jupe de guidage 32 est sensiblement cylindrique et de forme sensiblement correspondante à la section de la coque 4 au niveau de l'avancée 43. Ainsi, le poussoir 3 peut se déplacer axialement de manière parfaitement stable le long de l'axe commun X-X.27. The container 26 is here associated with a pusher 3 comprising an upper bearing surface 31 on the periphery of which extends downwards a guide skirt 32. This skirt 32 also forms, in association with a flange 33, a housing 34 to the interior of which the container 26 is received in a fixed and stable manner. The bottom 27 comes into contact with the bearing surface 31. The peripheral guide skirt 32 is adapted to slide without sealing inside the shell 4. More precisely, the shell 4 defines a guide projection 43 located just at the - Above the distribution orifices 510, 520. The guide skirt 32 is substantially cylindrical and of shape substantially corresponding to the section of the shell 4 at the level of the projection 43. Thus, the pusher 3 can move axially perfectly stable along the common axis XX.
La tête de distribution 5 comprend, outre ses deux canaux de distribution 51 et 52, deux manchons de raccordement 53 et 54 pour les extrémités libres respectives 111 et 121 des tiges d'actionnement respectives 11, 21. La tête 5 comprend également une douille de guidage 57 à l'intérieur de laquelle la pompe supérieure 2 ou sa bague de fixation peut se déplacer de manière axiale et stable le long de l'axe commun X-X. D'autre part, la tête 5 comprend plusieurs parois de guidage 55, 56 destinées à coulisser de manière non étanche à l'intérieur de la coque 4 pour assurer un déplacement axial et stable de la tête 5 le long de l'axe commun X-X.The distribution head 5 comprises, in addition to its two distribution channels 51 and 52, two connection sleeves 53 and 54 for the respective free ends 111 and 121 of the respective actuating rods 11, 21. The head 5 also includes a socket guide 57 inside which the upper pump 2 or its fixing ring can move axially and stably along the common axis XX. On the other hand, the head 5 comprises several guide walls 55, 56 intended to slide in leaktight manner inside the shell 4 to ensure an axial and stable movement of the head 5 along the common axis XX .
Ainsi, en appuyant sur la surface d'appui 31 du poussoir 3, la force d'appui est transmise au fond supérieur 27 du réservoir 25, puis à la pompe supérieure 2, ce qui a pour effet d'enfoncer sa tige d'actionnement 21 à l'intérieur du corps 22. De manière symétrique, la force d'appui enfonce la tige d'actionnement 11 dans le corps 12 de la pompe inférieure 1. En résultat, la tête de distribution 5 se déplace légèrement vers le bas. De manière concomitante, les produits fluides respectifs issus des deux tiges d'actionnement 11 et 21 s'écoulent à travers les canaux de distribution 51 et 52 pour parvenir simultanément ou consécutivement au niveau des orifices de distribution 510, 520. On peut prévoir des pompes ayant la même capacité de distribution, ou au contraire des capacités de distribution différentes. On peut également choisir des pompes ayant la même charge ou résistance d'actionnement, ou au contraire des pompes ayant des charges ou résistances d'actionnement différentes. Cela influera sur la quantité de produit distribué ainsi que sur la séquence de distribution des produits fluides au niveau des orifices de distribution respectifs. Il est plus facile de choisir des pompes ayant la même charge ou résistance d'actionnement.Thus, by pressing on the bearing surface 31 of the pusher 3, the bearing force is transmitted to the upper bottom 27 of the reservoir 25, then to the upper pump 2, which has the effect of driving its actuating rod 21 inside the body 22. Symmetrically, the pressing force pushes the actuating rod 11 into the body 12 of the lower pump 1. As a result, the dispensing head 5 moves slightly downwards. Concomitantly, the respective fluid products from the two actuating rods 11 and 21 flow through the distribution channels 51 and 52 to reach simultaneously or consecutively at the distribution orifices 510, 520. Pumps can be provided having the same distribution capacity, or on the contrary different distribution capacities. You can also choose pumps with the same actuation load or resistance, or on the contrary of pumps having different actuation loads or resistances. This will affect the amount of product dispensed as well as the distribution sequence of the fluid products at the respective dispensing ports. It is easier to choose pumps with the same actuation load or resistance.
On se référera maintenant au mode de réalisation de la figure 3. Les pompes 1 et 2 peuvent être identiques à celles du premier mode de réalisation. Il en est de même pour la tête 5. La différence principale avec le mode de réalisation précédent réside dans les réservoirs 15 et 25. En effet, le réservoir 15 est défini par un récipient déformable 16' qui peut par exemple être réalisé par injection soufflage. On peut également utiliser une poche souple Hbrement déformable réalisée à partir d'un film complexe. L'avantage avec ce genre de récipient déformable 16' est que le volume utile du réservoir 15 diminue à mesure que du produit fluide en est extrait par l'intermédiaire de la pompe. Dans ce mode de réalisation de la figure 3, le récipient 16' est une poche réalisée par injection soufflage comprenant un col sensiblement rigide 18. Le récipient 16' est maintenu à l'intérieur d'une enveloppe rigide 7 par l'intermédiaire d'un élément de maintien qui se présente sous la forme d'une collerette entourant le col 18 et venant en prise avec sa périphérie extérieure avec l'intérieur de l'enveloppe rigide 7. La pompe 1 est disposée à l'intérieur du col 18 et maintenue en place à l'aide d'une bague de fixation 6' qui définit un logement de fixation 61 pour la pompe 1 et une couronne de verrouillage 63 qui vient en prise avec l'enveloppe rigide 7 pour bloquer l'élément de maintien 8 en place.Reference will now be made to the embodiment of FIG. 3. The pumps 1 and 2 can be identical to those of the first embodiment. It is the same for the head 5. The main difference with the previous embodiment resides in the tanks 15 and 25. In fact, the tank 15 is defined by a deformable container 16 'which can for example be produced by injection blowing . One can also use a flexible pocket Deformably deformable made from a complex film. The advantage with this kind of deformable container 16 ′ is that the useful volume of the reservoir 15 decreases as fluid is extracted therefrom via the pump. In this embodiment of FIG. 3, the container 16 'is a pocket produced by injection blowing comprising a substantially rigid neck 18. The container 16' is held inside a rigid envelope 7 by means of a retaining element which is in the form of a collar surrounding the neck 18 and engaging with its outer periphery with the inside of the rigid envelope 7. The pump 1 is disposed inside the neck 18 and held in place with a fixing ring 6 'which defines a fixing housing 61 for the pump 1 and a locking ring 63 which engages with the rigid casing 7 to block the holding element 8 in place.
Le réservoir supérieur 25 est constitué par un récipient rigide 26' à l'intérieur duquel est disposé un piston-suiveur ou racleur 27'. Le piston-suiveur a pour fonction de se déplacer à mesure que du produit fluide est distribué par la pompe 2 pour diminuer le volume utile du réservoir 25. Ainsi, tout comme un récipient déformable, le système à piston-suiveur permet une distribution de produit fluide sans reprise d'air dans le réservoir. Le poussoir 231 est ici formé par un capuchon rapporté sur le fond ouvert du récipient rigide 26'. On peut même dire que le capot définit le fond du récipient 26'. Une autre particularité de ce mode de réalisation réside dans l'utilisation d'un ressort de réglage 215 disposé entre la pompe 2 et la tête de distribution 5. Ce ressort 215 permet de modifier la charge ou résistance d'actionnement de la pompe. La raideur du ressort de réglage 215 vient s'ajouter à la raideur du ressort interne de rappel de la pompe qui sollicite la tige d'actionnement vers sa position de repos. Ainsi, la charge totale de l'ensemble formé par la pompe et le ressort de réglage peut être réglée à une valeur recherchée en utilisant un ressort de réglage adéquat. C'est donc le ressort de réglage qui permet de régler la charge totale. On peut ainsi obtenir un distributeur duo équipé de deux pompes différentes possédant des charges ou résistances d'actionnement quelconques : le ressort de réglage 215 va permettre de régler la charge d'actionnement d'une pompe par rapport à la charge d'actionnement de l'autre pompe. Ceci permet par exemple d'équilibrer les charges des deux pompes. Ceci permet également de déséquilibrer les charges des deux pompes. Au niveau de la distribution, cela permet de déterminer la séquence de distribution provenant des deux pompes.The upper reservoir 25 is constituted by a rigid container 26 'inside which is disposed a piston follower or scraper 27'. The function of the follower piston is to move as fluid is distributed by pump 2 to reduce the useful volume of the reservoir 25. Thus, like a deformable container, the follower piston system allows product distribution fluid without air intake in the tank. The pusher 231 is here formed by a cap attached to the open bottom of the rigid container 26 '. We can even say that the cover defines the bottom of the container 26 '. Another particular feature of this embodiment lies in the use of an adjustment spring 215 disposed between the pump 2 and the dispensing head 5. This spring 215 makes it possible to modify the load or actuation resistance of the pump. The stiffness of the adjustment spring 215 is added to the stiffness of the internal return spring of the pump which biases the actuating rod towards its rest position. Thus, the total load of the assembly formed by the pump and the adjusting spring can be adjusted to a desired value using an adequate adjusting spring. It is therefore the adjustment spring which makes it possible to adjust the total load. One can thus obtain a duo distributor equipped with two different pumps having any actuation loads or resistances: the adjustment spring 215 will make it possible to adjust the actuation load of a pump relative to the actuation load of the other pump. This allows for example to balance the loads of the two pumps. This also makes it possible to unbalance the loads of the two pumps. At the distribution level, this determines the distribution sequence from the two pumps.
Le produit fluide d'une pompe peut être distribué avant celui de l'autre pompe. On peut également obtenir une distribution simultanée. On assure ainsi une distribution séquencée souhaitée des produits fluides issus des deux pompes. On peut également jouer sur la section et la largeur des canaux de distribution pour déterminer la séquence de distribution.The fluid from one pump can be dispensed before that from the other pump. You can also get simultaneous distribution. This ensures a desired sequenced distribution of the fluid products from the two pumps. We can also play on the section and the width of the distribution channels to determine the distribution sequence.
Grâce à l'utilisation de réservoir sans reprise d'air, on peut se passer du tube plongeur et du tube d'éventation du premier mode de réalisation. On peut également remarquer que le poussoir peut se présenter sous la simple forme d'un fond de récipient de réservoir. La coque 4 est également très facile à fabriquer et permet de masquer tous les éléments constitutifs du distributeur duo. Thanks to the use of a reservoir without air intake, one can do without the dip tube and the vent tube of the first embodiment. It can also be noted that the pusher can be in the simple form of a tank container bottom. The shell 4 is also very easy to manufacture and makes it possible to hide all the constituent elements of the duo dispenser.
