    专利说明:

    The present invention relates to a duo distributor comprising two different fluid product reservoirs, two pumps and a common distribution head, this common distribution head comprising an outlet channel forming an outlet orifice, this outlet channel being fed with the fluid products from both pumps. The preferred fields of application of the present invention are those of cosmetics and pharmacy, or even perfumery.
    In the prior art, dual dispensers have long been known to dispense two different fluid products from separate reservoirs through a single common dispenser port. FR2654016 is an example: it describes a duo distributor comprising a rotary wedge which is movable above the actuating rod of one of the pumps to vary the depression of the actuating rod, and therefore the dose to mix with the dose driven by the other pump.
    The present invention is not intended to vary the dose dispensed by the pumps by acting on the stroke of one of the actuating rods, but rather to phase out the distribution of fluid products at the end of the race, so that a only fluid product is distributed through the dispenser orifice at the end of the dispensing phase. In other words, the dispensing orifice is in contact with only one fluid product out of the dispensing phase, or the dispenser orifice is in contact with the two fluid products only during the dispensing phases.
    To achieve this goal, the present invention provides a dual dispenser comprising two pumps respectively associated with two different fluid product reservoirs and a common dispensing head, said common dispensing head comprising an outlet channel forming an outlet orifice, said dispensing channel. the outlet being fed with the fluid products from the two pumps, in which: the two pumps comprise actuating rods axially displaceable on strokes of different lengths, namely a first actuating rod having a long stroke and a second rod; actuator having a short stroke, - the common dispensing head comprises a pivoting member which forms two bearing elements for simultaneously moving the two actuating rods to an axial height corresponding to the short stroke, the bearing elements continuing then their movements by pivoting / rotating the pivoting member to finish the long race.
    Thus, the two bearing elements travel, from the rest position of the common distribution head, first an identical path, symmetrical and synchronous, then, when the second actuating rod having a short stroke has been fully depressed, the support elements initiate a pivotal / rotational movement of the pivoting member, so that the bearing element associated with the first actuating rod having a long stroke continues its axial path until that the first actuating rod is fully depressed. It is preferable that the actuating forces of the two actuating rods are substantially or perfectly identical. Otherwise, it is necessary to provide axial guiding means that allow an identical, symmetrical and synchronous displacement of the two support elements.
    According to an advantageous characteristic of the invention, the two support elements are integral in displacement from one another. Preferably, the two support elements are integral with the outlet channel. More preferably still, the two support elements extend on both sides of the outlet channel, advantageously symmetrically. The output channel may for example be straight over at least a portion of its length, and the two support members may extend symmetrically opposite from the channel.
    According to another advantageous aspect of the invention, the two support elements pivot around the outlet channel. This induces a slight rotation of the outlet channel on itself, since it acts as a pivot axis for the two support elements.
    According to another advantageous aspect of the invention, the pivoting member may comprise at least one thrust transmission zone, and advantageously two, so that an axial thrust exerted on this thrust transmission zone first causes the displacement translating the two support elements and the output channel on the short stroke, then then a slight rotation of the output channel on itself and the pivoting of the support elements to complete the long run. In other words, the outlet channel and its two support elements first move translatively on the short stroke, then pivot about the contact point of the bearing member which abuts at the level of the second operating rod fully depressed. The support element associated with the first actuating rod continues its downward movement, not in a translative manner, but on the contrary by describing an arc whose radius corresponds to the distance between the contact points of the two support elements. The exit channel also describes a slight arc, but a lower radius, ie half that of the support elements.
    According to another advantageous characteristic of the invention, the common distribution head comprises a hood which comes into bearing contact on the thrust transmission zones. Advantageously, the outlet channel comprises a thrust transmission zone near each of its ends. Advantageously, the support elements extend substantially perpendicularly to the outlet channel between the two thrust transmission zones. The formation of two zones of thrust transmission makes it possible to distribute the thrust in a balanced manner over the length of the outlet channel, and the fact of positioning the transmission zones at the ends of the channel makes it possible to keep the channel perfectly stable during its operation. displacement.
    According to a very interesting aspect, the first actuating rod having the long stroke can be connected to the outlet channel closer to the dispensing orifice than the second actuating rod having the short stroke. Thus, the fluid product from the first actuating rod (having a long stroke) will pass alone and last through the dispensing orifice during each dispensing phase, so that in the rest position, it will There is only the fluid product from the first actuating rod at the dispensing orifice. This is particularly advantageous when the fluid product from the second actuating rod is sensitive, "denatable" or "deteriorated" in contact with the air. By using a fluid product (derived from the first actuating rod) which is more stable and / or with disinfecting or bactericidal properties, it is ensured that there will be no contaminated or altered residue of fluid product at the level of the fluid. dispensing orifice.
    According to a practical embodiment, each actuating rod may be capped with a cap defining a support plate for its respective support element and a connecting end receiving a flexible conduit which connects the outlet channel. This cap can simply be force-fitted on the free end of the actuating rod. The spirit of the invention lies in the principle of actuating the two pumps via a rotary member which moves first translatively on the race common to the two pumps, and then by rotation or pivoting to complete the actuation of the pump with the longest stroke. Thus, one of the pumps will dispense the fluid product after the other pump at the end of the dispensing phase to expose the dispensing orifice, and a section of the outlet channel, only to a single fluid product, which will advantageously have stable properties disinfectant and / or bactericidal. The invention will now be described in more detail with reference to the accompanying drawings, giving by way of non-limiting example, an embodiment of the invention.
    In the figures: - Figure 1 is an exploded perspective view of a dispenser according to the present invention, the two tanks not shown, - Figure 2 is a vertical cross-sectional view through the dispenser of the FIG. 1 in the assembled state in the rest position, in the absence of reservoirs, FIG. 3 is a top view in transparency of FIG. 2, FIG. 4 is a view similar to that of FIG. the dispensing head having made the short stroke, and - Figure 5 is a view similar to that of Figure 4 with the dispensing head having made the long stroke.
    Reference will be made independently to FIGS. 1 to 3 to describe in detail the structure of a duo dispenser according to the invention capable of simultaneously dispensing two fluid products of different natures, textures and / or properties. The entire dispenser will be described with the exception of the two fluid reservoirs containing the different fluid products. An optional hull containing the two tanks is not shown either. In any case, the two tanks as well as the shell are not critical for the present invention, which is located at the top of the dispenser.
    Thus, the dispenser of the invention comprises two pumps P1 and P2 each comprising a pump body P10 and P20 and two actuating rods P11 and P21 which are movable axially back and forth in their respective pump bodies P10 and P20 against a return spring not shown. Actuating rods P11 and P21, which protrude upwards from the bodies P10 and P20, are movable on different stroke heights, namely a long stroke for the actuating rod P11 and a shorter stroke for the rod. actuator P21. The pumps P1 and P2 each define a pump chamber of the same or different volumes. On the other hand, it can be advantageous for the actuating rods P11 and P21 to have a resistance that is substantially identical to or the same as the depression. Otherwise, it would be necessary within the scope of the invention specific means to compensate for any difference in resistance to depression of the two actuating rods.
    Each pump P1, P2 also comprises a fixing ring P12, P22 for fixedly mounting and sealing the pump on the neck of a respective reservoir (not shown). The type of attachment is not critical to the present invention.
    The duo distributor of the invention also comprises a telescope 3 defining two receiving housings 3P1 and 3P2, respectively for the pumps P1 and P2. As can be seen in FIG. 2, the fastening rings P12 and P22 are tightly received within the two receiving housings 3P1 and 3P2 in order to lock the rings on the necks of the tanks. This is a configuration quite classic in the field of cosmetics. The telescope 3 can cooperate with a shell (not shown) in which are received the two tanks (not shown).
    The dual dispenser of the invention also comprises two caps C1 and C2 which cap respectively the free ends of the actuating rods P11 and P21, as can be seen in Figure 2. The caps C1 and C2 may be identical, or slightly different, for example to adapt to actuating rods of different diameters. Each cap C1, C2 comprises a support plate C11, C21 and a lateral connection end C12, C22. This connection piece communicates directly with the actuating rods P11, P21, so that the fluid products discharged through the actuating rods reach its two connecting pieces C12, C22. The support plates C11, C21 extend substantially perpendicular to the axis of movement of the actuating rods P11, P21. Advantageously, each support plate is partially surrounded by a notched crown C13, C23.
    The duo distributor of the invention also comprises a pivoting member 1, which may advantageously be made integrally. This pivoting member 1 comprises an outlet channel 10, which here has a rectilinear configuration. This outlet channel 10 is closed at one of its ends and defines at its other end an opening 12 in which is embedded a nozzle 13 which defines a dispensing orifice 14. Thus, the fluid product that arrives in the outlet channel 10 in out through the dispensing orifice 14 of the nozzle 13 which closes the opening 12. It may also be noted that the two ends of the channel 10 are reinforced so as to define two thrust transmission zones 11, as will be explained hereinafter. after. The outlet channel 10 comprises two connecting pieces 16, 17 which each receive a flexible duct 18, 19 respectively connected to the connection ends C12, C22 of the two caps C1 and C2. The flexible ducts 18 and 19 can be embedded in the end pieces 16, 17, C12 and C22, or, alternatively, be made integrally with either the pivoting member 1, or with the caps C1 and C2. It is more clearly seen in FIG. 3 how the flexible ducts 18 and 19 connect the end pieces 16, 17, C12 and C22, exhibiting a bent configuration. It can be seen in FIGS. 1 and 3 that the tip 16 is disposed near the nozzle 13, and therefore the dispensing orifice 14, while the connection tip 17 is located near the end opposite the nozzle 13. Therefore, the fluid product from the pump P1 and traveling through the cap C1 and the flexible conduit 18 is injected into the outlet channel 10 in the direct vicinity of the dispensing orifice 14. The fluid product from the pump P2 must instead traverse the entire length of the duct of the outlet channel 10. The pivoting member 1 also forms two support elements 1C1 and 1C2 which extend perpendicular to the outlet channel 10 symmetrically and opposite . It could be said that the outlet channel 10 and the two support elements 1C1 and 1C2 have an overall configuration in the shape of a cross. As a result, the two supporting elements 1C1 and 1C2 are integral with each other via the outlet channel 10. Each support element is in the form of an elongate tab which defines its free end, a bearing head 15 which is oriented downwards, and which comes into contact with the support plate C11, C21 of the caps C1, C2, as shown in Figure 2. The support elements 1C1 and 1C2 extend through the indentations of the indented crowns C13 and C23 to allow their respective bearing heads 15 to come into contact with the support plates C11, C21. Advantageously, the support heads 15 extend in the extension of the actuating rods P11, P21. It may also be noted that the bearing elements 1C1 and 1C2 are connected to the outlet channel 10 substantially midway between the two thrust transmission zones 11 situated at the two opposite ends of the channel 10.
    The duo distributor of the invention also comprises a cover 2, here oval, which defines an upper bearing surface 21 and a peripheral skirt 22 which is pierced with a hole 23 which will come opposite the nozzle 13 The cover 2 also comprises a retaining sleeve 24 in which the cap C1 is fixedly received. On the other hand, the cover 2 also comprises a guide sleeve 25 which surrounds the cap C2, allowing it to slide inside. As can be seen in Figure 2, the skirt 22 of the cover 2 extends around the bezel 3, so as to completely hide the caps C1, C2 and the dispensing member and support 1.
    The two caps C1 and C2, the pivoting member 1 and the cover 2 together form a fluid dispensing head, which is common to both pumps P1 and P2.
    In FIG. 2, the dispenser is in its rest configuration, with the two actuating rods P11 and P21 in their extended position as far as possible out of their respective pump bodies P10, P20. The two support plates C11 and C21 are located substantially or perfectly at the same height. It is obviously the same for the two support heads 15 of the two support elements 1C1 and 1C2. The lower face of the support surface 21 of the cover 2 is in contact with the outlet channel 10 at the two thrust transmission zones 11. From this rest position, the user can press with the help of one or more fingers on the bearing surface 21 of the cover 2 with a pushing force sufficient to move the cover 2 towards the bezel 3. The thrust thus exerted on the cover 2 is transmitted to the outlet channel 10 at the level of these two areas of thrust transmission 11. Next, the thrust force is transmitted through the two thrust members 1C1 and 1C2 to the bearing heads 15 which are in pressed contact against the support plates C11 and C21. The thrust is then transmitted to the actuating rods P11 and P21, which are forced to sink inside their respective pump bodies P10 and P20. Due to the fact that the actuating rods P11 and P21 have the same or almost identical resistance to being driven, and because the bearing elements 1C1 and 1C2 are symmetrically identical, the two actuating rods P11 and P21 sink simultaneously until the operating rod P21, which has the smallest stroke, is fully depressed. This intermediate and instantaneous position is shown in FIG. 4. The two actuating rods P11 and P21 then performed the same stroke, namely the short stroke which is the maximum stroke of the actuating rod P21. The different fluid products from the two pumps P1 and P2 were then simultaneously run in parallel through their respective actuating rods P11, P21, their respective caps C1, C2, their respective flexible ducts 18, 19 to reach the channel 10 or the two fluid products are mixed before being distributed through the single common distribution port 14. The simultaneous distribution of the two fluid products has taken place from the rest configuration of Figure 2 to the configuration intermediate of Figure 4. The user who continues to exert a pressure force on the bearing surface 21 will still move the cover 2 down, transmitting the thrust to the pivoting member 1 at the two zones of pushing transmission 11 of the outlet channel 10. Since the head 15 of the support element 1C2 is locked in position because the actuating rod P21 is compliant ment pressed, the thrust transmitted to the output channel 10 induces an additional downward displacement of the support head 15 of the 1C1 support element. This has the effect of fully driving the actuating rod P11, so that it then made its full long run. During this complementary race, the fluid product from the pump P1 was injected into the outlet channel 10 and then through the dispensing orifice 14. It should be noted that only the fluid product from the pump P1 passes through the dispensing orifice 14 at the end of the dispensing phase, the distribution of the other fluid product from the pump P2 having been completed when the actuating rod P21 has made all of its short stroke.
    Comparing FIGS. 4 and 5, it can be seen that the orientation of the two support elements 1C1 and 1C2 has been modified. Indeed, in FIG. 4, the two support elements 1C1 and 1C2 extend in a substantially horizontal plane, whereas in FIG. 5, these same support elements extend in a plane which is slightly inclined towards the right. Therefore, referring to the cover 2, the support members 1C1 and 1C2 have made a slight pivoting or rotation movement about the point of contact of the bearing head 15 against the support plate C21. It is the same for the output channel 10 which has performed a corresponding slight pivoting. On the other hand, referring to the outlet channel 10, it can be said that the outlet channel (10) has made a slight rotation on itself and the support elements (1C1, 1C2) have made a pivoting movement around the exit channel (10) to end the long run.
    The fact that the pump P1 dispenses fluid alone at the end of the dispensing phase eliminates the fluid product from the pump P2 when the dispenser is in the rest position. Thus, the fluid product from the pump P2 is present at the dispensing orifice 14 only during the distribution phase, and still not in its entirety, since at the end of the distribution phase only the product from the pump P1 passes through the dispensing orifice 14. It can then be recalled that the fluid product from the pump P1 is injected into the outlet channel 10 near the nozzle 13, at the connection tip 16, as can be seen in FIG. 3. This implies that a very small amount of fluid produced from the pump P1 is sufficient to remove the fluid product from the pump P2 at the dispensing orifice 14, at the end of the distribution phase. In the rest position as shown in FIG. 4, the fluid product coming from the pump P2 fills most of the outlet channel 10, with the exception of its end close to the nozzle 13.
    The duo dispenser of the present invention is particularly advantageous for dispensing two fluid products of different types and / or properties. For example, the fluid dispensed by the pump P2 may be a sensitive fluid or easily degradable, while the fluid dispensed by the pump P1 may be a fluid product more stable, more resistant or still having bactericidal or disinfecting properties. For example, it is possible for the pump P1 to dispense an alcoholic solution. Thus, at the end of each distribution phase, the dispensing orifice 14 is cleaned by the passage of a minute dose of alcoholic solution which ensures perfect cleanliness of the nozzle 13.
    Thanks to the invention, there is a duo distributor whose dispensing orifice can not be the seat of a proliferation of microbes or bacteria, which could be harmful to the dispensed fluid products or to the user.
