Definitions
- a system for dispensing a liquid such as perfume includes a liquid dispensing apparatus and a liquid reservoir.
- Such systems are known for dispensing a liquid such as perfume and which each comprise a device for pumping liquid and dispensing the pumped liquid as well as a liquid reservoir on which the device is permanently mounted.
- a device for pumping liquid and dispensing the pumped liquid as well as a liquid reservoir on which the device is permanently mounted.
- the second end of the dip tube forms a perforation member which extends to the bottom of the reservoir in order to pump the liquid there under the action of the pump.
- the dimensioning of the rigid tube must be very precise so that the tube is able to reach the bottom of the tank without however touching it so as not to damage it.
- the tube must therefore be of a length less than the inner length of the tank, which will therefore not guarantee its complete emptying.
- the invention provides for remedying at least one of the aforementioned drawbacks by proposing a new liquid distribution system that is more reliable than those of the prior art.
- the subject of the invention is thus a system for distributing a liquid in accordance with claim 1.
- the liquid reservoir is not an integral part of the device but is installed in it removably.
- the tank has its own liquid return (or rise) system (internal suction tube or dip tube) which reacts under the action of a vacuum caused by the pumping and distribution device in order to bring the liquid back up. from the bottom of the tank to the top of it.
- the main hollow needle only serves as a first interface to, on the one hand, perforate the reservoir and, on the other hand, allow the liquid brought from the bottom of the reservoir to exit from the latter and be conveyed to the device. pumping and distribution.
- the main hollow needle does not have the function of fetching the liquid from the bottom of the reservoir as in the prior art and is therefore not part of the liquid return system. Thus, there is no need to size a hollow needle very precisely so that it can pick up the liquid at the bottom of the tank without damaging it, the tank being in fact already equipped with its own liquid return system. .
- the secondary hollow needle serves, for its part, as a second interface for, on the one hand, perforating the reservoir and, on the other hand, bringing the external air of compensation inside the reservoir (return means d 'air).
- the apparatus according to the invention is judiciously designed so that the said at least two main and secondary needles serving as fluidic interfaces (as explained above) between the pumping and distribution device and the reservoir are integral with one part. intermediary of the apparatus which is distinct from said device.
- the device can be a device conventional as found in the trade and only the part of the device comprising the part with the needles is specific.
- the device for pumping and dispensing liquid can therefore be replaced without having to touch the part to which said at least two needles are subject.
- the device is therefore particularly simple to design and manufacture since it does not require the design of a specific pump.
- the pumping and liquid distribution device used in the device incorporates in itself its own ventilation system.
- the configuration of the device is therefore simple since it uses the sealing capacity of the venting system of the pumping device and therefore does not require a separate and independent venting system: when the pumping device is not activated, the venting system is not activated and outside air cannot enter the device and the secondary needle. On the contrary, when the device is actuated, the outside air enters the device via the venting system which is open and reaches the secondary needle and therefore the reservoir with which the needle. makes the connection.
- the activation of the venting system therefore does not require a separate action on the part of the user since it systematically intervenes as soon as the pumping action is exerted by the user.
- the liquid is pumped from the bottom of the tank through the free end of the dip tube, rises in the main needle which is connected to the tube and passes through the pumping and dispensing device to be distributed outside.
- the fluid circuits or paths for air and liquid are sealed with respect to each other so as not to disturb or even hinder the operation of the system (the two circuits or paths are physically separated in order to avoid preferentially sucking in air when pumping liquid).
- the secondary needle is not in contact with the main needle in the reservoir insofar as said main needle is tightly connected to the dip tube.
- the liquid reservoir When the liquid reservoir is empty, it is removed from the device and another full reservoir is put in its place.
- the device can therefore be reused a many times without having to throw away the entire distribution and pumping system (device and tank).
- the mounting of the needles on an intermediate part of the device (forming a needle support), independent of the pumping and dispensing device, makes it possible to fix the needles more reliably (for example by overmolding) than on said device.
- the risks of the needles detaching from the part forming the support over time are reduced compared with the apparatus of the the aforementioned prior art.
- hollow needles for example of the hypodermic needle type, makes it possible to have a liquid reservoir which is permanently closed (during transport and use) and which does not need to be opened in order to be used. In fact, it suffices to introduce the reservoir into the device and to put it in place in the position of use by pushing it towards the needles so that they perforate the reservoir (more particularly the means of plugging or closing the tank) and that, by actuating the distribution device, liquid can be distributed (eg sprayed) and air introduced into the tank.
- the simple gesture of removing the empty tank from the device allows you to disengage the needles from the tank and replace the empty tank with a full tank.
- the main needle is not intended to go to the bottom of the reservoir insofar as the latter already incorporates its own liquid return system (dip tube). Therefore, the length of the needle must be sufficient to be able to perforate the reservoir and penetrate inside without having to extend to the bottom as in the prior art.
- the length of the main needle (like that of the secondary needle) is thus considered to be small in relation to a main dimension of the reservoir, for example in relation to the length or height of the reservoir if the latter has a general shape. elongated, for example substantially cylindrical.
- the needles can be much shorter than the piercing tube of the above apparatus. It follows that the race to be carried out by the needles to exit the reservoir is much smaller than in the prior art, which can make the withdrawal movement easier. Moreover, as these needles are short, the risk of breaking them is lower than in the prior art. In addition, the part of the main needle capable of plunging into the liquid is small (or zero depending on the arrangement) so that the reservoir change can be carried out cleanly, without the liquid dripping. Finally, as the needles are short, it is possible to provide a covering to hide them and prevent the user from injuring himself, whereas in the state of the art, it is impossible to produce a covering completely masking the needle. at the risk of not being able to access the tank.
- the needles can be arranged in different configurations: side by side in a contiguous manner or well apart from one another, centered or not with respect to the tank, concentric with respect to one another, etc. .
- the needles can also adopt different lengths with respect to each other, or even different internal diameters.
- the needles usually have a bevel-cut perforator end like the hypodermic type needles.
- the dip tube can be flexible (plastic), which facilitates its installation inside the reservoir to the bottom thereof.
- the flexible dip tube can be longer than the interior height of the reservoir and, because of its flexibility, it therefore curves in contact with the bottom of the reservoir, thus making it possible to guarantee the full return of the liquid. This configuration allows it to absorb the variations in height that may exist from one tank to another.
- the invention further relates to a method of installing a liquid reservoir in a liquid distribution apparatus of a liquid distribution system as briefly described above, the method comprising the introduction of the reservoir in the apparatus and its placement in said apparatus in a position of use in which said at least two hollow needles perforate the liquid reservoir with a view to sucking the liquid therefrom as a result of a pumping action on the device for pumping liquid and distributing the pumped liquid.
- the figure 6 shows tank R without the device.
- the device A has a generally elongated shape along a Z axis (this axis corresponds to the vertical axis when the device is in the vertical position of use as on the figure 1a ).
- Apparatus A more particularly comprises an outer casing 12 having a generally hollow cylindrical shape.
- the casing 12 has two opposite open ends 12a, 12b which are arranged along the longitudinal axis Z.
- the cylindrical shape of the outer casing 12 extends from its so-called lower end 12b over almost its entire height. Near the upper end 12a the casing takes the shape of a truncated cone towards the end 12a to form a reduced opening relative to the opening of the opposite lower end 12b.
- the apparatus A comprises a device 14 for pumping liquid and distributing the pumped liquid which is mounted at the upper end 12a of the casing as shown generally in FIG. 1a.
- Device 14 includes an upper block 16 which protrudes beyond the opening in end 12a.
- This block comprises a first so-called distribution part 18 which extends transversely along almost the entire diameter of the opening of the upper end 12a.
- the part 18 is partially recessed in its central part to receive, from below, a second part 20 elongated perpendicularly along the axis Z.
- the part 18 is provided, in its peripheral part, with a liquid distribution member 22 ( here, it is a spray device) which opens onto the outside.
- the second part 20 is pierced along its entire height (along the Z axis) with a central through channel which communicates with the liquid distribution member 22 via channels internal to the part 18.
- the upper block 16 is covered, in its part projecting above the opening of the upper end 12a, with a cap 23 which can slide through the opening following a bearing on said cap.
- the apparatus comprises a lower block 30 housed inside the casing 12 and which extends from a lower zone located at a distance from the lower end 12b of the envelope to a high zone located in the part. of the envelope in the form of a truncated cone.
- the lower block 30 comprises a cylindrical body 32 open at its lower end 32a and closed at its upper end 32b by a transverse wall 34.
- This wall 34 is surmounted by a hollow neck 36 of diameter smaller than the diameter of the body 32 and which s 'extends to the upper zone located in the part of the envelope in the form of a truncated cone.
- the neck 36 defines an internal housing.
- a cylindrical-shaped part 38 forming a turret extends axially into the internal housing from the wall 34 and is surmounted by a cylindrical chimney 40.
- the assembly formed by the body 32 and the neck 36 has an axial symmetry with respect to a central longitudinal axis S ( fig.2 ).
- the lower block 30 is centered inside the casing 12 and the S axis coincides with the Z axis.
- the part 38 is eccentric with respect to the axis of axial symmetry S but the chimney 40 is aligned along this axis.
- the part 38 is pierced in its height or thickness (Z axis) by two through channels 38a, 38b parallel.
- the central channel 38a is aligned with the axis S and the chimney 40 which extends it upwards.
- the eccentric channel 38b is disposed between the central channel 38a and the wall of the neck 36.
- the channel 38a surmounted by the chimney 40 and the channel 38b each place the interior of the body 32 in communication with the internal housing of the neck 36.
- the device 14 also comprises a part 42 of generally elongated shape which has a body 42a pierced in its center by an elongated through channel 42b aligned along the Z axis.
- the part 42 comprises a cylindrical skirt 42c which extends from from an upper end of the body, upwards away from said body.
- the skirt is shaped so as to provide inside said skirt a central cavity 42d aligned with the through channel 42b.
- the skirt 42c is provided with an external shoulder.
- the part 42 is engaged inside the internal housing of the neck 36 and is fixed to the part 38 so that the chimney 40 is fitted inside the through channel 42b.
- the outer shoulder of the skirt 42c rests on a washer 44 which is itself mounted to bear on the free upper edge of the neck 36.
- a cap 46 has a profile in axial section ( fig.1a ) which follows the external profile of the skirt 42c, of its shoulder and of the washer and covers these elements.
- the cover 46 is pierced in its middle in order to let the second part 20 of the upper block 16 partially penetrate and slide inside the central cavity 42d.
- a ventilation system (not shown on the figure 1a ) is integrated into the device 14, as on most pumps used in perfumery, in order to put the outside of the device in communication with the internal housing at the neck 36 for the return of air necessary for the operation of the dispensing system. liquid.
- the figure 1b illustrates in more detail an example of a liquid pumping and dispensing device which can be used to form the device 14 of figures 1b and 1c .
- the device 14 is mounted directly on a tank conventional 1 while in Figure la it is mounted on an apparatus to which a reservoir is connected via hollow needles which will be described below.
- the device 14 also comprises a first upper valve system 29 (seat 29a and movable valve 29b such as a ball) arranged between the piston and the rod and a second lower valve system 31 (seat 31a and movable valve 31b such as a ball) arranged in the lower part of the sleeve 42.
- a first upper valve system 29 (seat 29a and movable valve 29b such as a ball) arranged between the piston and the rod
- a second lower valve system 31 (seat 31a and movable valve 31b such as a ball) arranged in the lower part of the sleeve 42.
- the sleeve 42 has one or more through holes 33 in its wall which delimits the chamber or cavity 42d inside which the piston 21 slides.
- This or these holes 33 are made in an area of the wall at the level (altitude) of which is the piston 21 when the device is in its rest position, that is to say when the pumping device is not actuated ( figure 1b ).
- the hole or holes 33 place a first space inside the reservoir and which surrounds the liner 42 with a second space located between the body of the piston 21 and the internal surface of the wall of the liner in communication.
- This second space does not communicate with the remaining part of the sleeve (both above the piston and below) due to the tightness of the contact between the body of the piston 21 and the wall of the sleeve 42, via the lips top and bottom sealing on the piston body.
- the cover 46 and a part 47 (optional) located below are drilled in their center and the central hole has a diameter greater than the outer diameter of the rod 27 in its portion 27a in order to release a radial space 35 between the edges of the central hole and the rod.
- the enlarged diameter portion 27b of the rod abuts against the part 47, thus preventing the radial space 35 open to the outside from communicating with the inside of the jacket 42.
- the venting of the device is therefore not activated because the pumping device is not activated.
- a fluid path is thus established between the exterior of the device and the interior of the reservoir for the external compensation air.
- the venting system is thus formed by the radial space 35 and the hole or holes 33 which are placed in communication with each other following the actuation of the device (insertion of the part 20 into the room 42)
- a so-called main hollow needle 50 is fixed, by overmolding, inside the central channel 38a on the side of the wall 34 which faces the housing internal to the body 32.
- the main needle 50 thus fixed in the wall 34 of the body which it passes through, protrudes into the aforementioned housing by a free perforating end 50a.
- the main needle 50 inserted into the channel 38a thus places the internal housing of the body 32 (in which a liquid reservoir is inserted) in communication with, successively, the chimney 40, the cavity 42d, the channel 20a of the second part 20 and the channels internal to the first distribution part 18 (liquid distribution member 22).
- a so-called secondary hollow needle 52 is fixed, by overmolding, inside the peripheral channel 38b on the side of the wall 34 which faces the internal housing of the body 32.
- each needle 50, 52 can be force-fitted or glued inside its channel.
- the secondary needle 52 thus fixed in the wall 34 of the body which it passes through, protrudes into the aforementioned housing by a free perforating end 52a.
- the secondary needle 52 puts the internal housing of the body 32 in communication (permanently) with the internal housing of the neck 36 and (temporarily) with the exterior of the device (of the system), via the venting system described above with reference to the figures 1b and 1c , when actuating the pumping device 14.
- the needles are for example of the hypodermic type and for example have the same lengths. However, in a variant not shown, their respective lengths may be different from one needle to another.
- the needles have lengths which are much less than the length of the body 32 (and therefore of the device) insofar as their function is not to fetch the liquid from the reservoir but only to serve as fluidic interfaces in two separate fluidic circuits (for the liquid and for the external compensation air) and sealed with respect to each other.
- the reservoir itself comprises an integral liquid return system which acts in response to a suction of air created by the pumping device 14. It will be noted that the two needles are thus mounted on a part. (the needles are attached to part 32) separate and independent of the pumping and dispensing device 14 (part 42 and upper block 16).
- the upper block 16 is axially movable along the Z axis relative to the fixed lower block 30 when a user exerts pressure on the cap 23. More particularly, as already mentioned above with reference to figure 1c , the second part 20 is able to slide inside the cavity 42d, which allows, when the second part 20 rises, to create a depression in all the aligned channels and in the main needle 50 in order to suck up liquid.

- the spring 93 is compressed between the upper 60 and lower stops 78a, 80a and 82a.
- the apparatus A is then ready for use in the position of use illustrated in FIG.

- the secondary needle 52 concomitantly ensures an entry of air into the reservoir during pumping of the liquid in order to compensate for the volume of pumped liquid.

- the two circuits or fluidic paths are separated and sealed from one another.
- the perforating end of the secondary needle 52 through which the outside air enters the reservoir opens into an upper zone remote from the lower zone in which the liquid is pumped.
- the pumped liquid circulates in the dip tube, the cavity 106, the main needle 50 and the part 42 which are mounted in a sealed manner relative to each other, thus preventing any encounter between the air and the liquid.
- the reservoir R is removed when all (or almost) of the liquid has been consumed or else for other reasons (eg: wish of the user to change perfume). To do this, simply press on the bottom of the tank as indicated by the arrow on the figure 8c (same movement to be performed as to insert the tank at the figure 8a ).
- the second tab 94 which is then no longer constrained laterally by the hook 62c in the direction of the tab 92 is then elastically brought back laterally in a position parallel to that of the first tab 92 as illustrated in FIG. figure 8e .
- the sleeve is no longer locked and the spring 94 is released by pushing the sleeve down in the direction indicated by the arrow on the figure 8e .
- the tab 94 is however still radially constrained by the wall of the body 32 as long as the descent of the sheath continues and until it reaches the portion 62a of the slot 62.
- the lug 94a then engages there naturally in an elastic manner to return to it. to its undeformed shape of the figure 8a .
- the reservoir can then be simply removed by the user by pulling with the fingers on the open end. Since the main needle does not soak in the liquid, the withdrawal of the reservoir can be carried out more cleanly than in the prior art.
- the liquid reservoir does not need to be opened by the user to gain access to the liquid.
- the device is simple and reliable in design.
- the needles 50 and 52 are inaccessible from the outside of the apparatus because they are protected by the casing 12 and the body 32.
- the needles are arranged at the bottom of the internal housing of the elongated body 32 which is itself arranged set back from the opening of the lower open end 12b of the envelope.

Description
L'invention concerne un système de distribution d'un liquide tel que du parfum, comprenant un appareil de distribution de liquide et un réservoir de liquide.A system for dispensing a liquid such as perfume includes a liquid dispensing apparatus and a liquid reservoir.
On connait de tels systèmes de distribution d'un liquide tel que du parfum et qui comprennent chacun un dispositif de pompage de liquide et de distribution du liquide pompé ainsi qu'un réservoir de liquide sur lequel est monté de façon permanente le dispositif. Lorsque le liquide est épuisé il faut jeter l'appareil et en acheter un nouveau rempli de liquide.Such systems are known for dispensing a liquid such as perfume and which each comprise a device for pumping liquid and dispensing the pumped liquid as well as a liquid reservoir on which the device is permanently mounted. When the liquid is used up, the device must be discarded and a new one filled with liquid must be purchased.

- un dispositif de pompage et de pulvérisation du liquide pompé comprenant un pulvérisateur, une pompe et un tube plongeur rigide raccordé par une première extrémité à la pompe,
- un réservoir possédant une pastille qui est perforable par la deuxième extrémité du tube plongeur.
- a device for pumping and spraying the pumped liquid comprising a sprayer, a pump and a rigid dip tube connected by a first end to the pump,
- a reservoir having a pellet which can be punctured by the second end of the dip tube.
La deuxième extrémité du tube plongeur forme un organe de perforation qui s'étend jusque dans le fond du réservoir afin d'y pomper le liquide sous l'action de la pompe.The second end of the dip tube forms a perforation member which extends to the bottom of the reservoir in order to pump the liquid there under the action of the pump.
Ce système n'est toutefois pas satisfaisant. En effet, il nécessite de remettre en question la conception et la fabrication des dispositifs de pompage et de pulvérisation conventionnels en leur adjoignant un tube rigide. La fiabilité au cours du temps de la tenue mécanique du tube au dispositif d'un tel appareil est loin d'être prouvée, notamment en raison des multiples mouvements de retrait du réservoir pour en retirer le tube.However, this system is not satisfactory. In fact, it requires questioning the design and manufacture of conventional pumping and spraying devices by adding a rigid tube to them. The reliability over time of the mechanical strength of the tube to the device of such a device is far from being proven, in particular because of the multiple movements of withdrawal of the reservoir in order to remove the tube therefrom.
Par ailleurs, le dimensionnement du tube rigide doit être très précis pour que le tube soit apte à atteindre le fond du réservoir sans toutefois le toucher afin de ne pas l'endommager. Le tube doit donc être d'une longueur inférieure à la longueur Intérieure du réservoir, ce qui ne permettra donc pas de garantir son vidage intégral.Furthermore, the dimensioning of the rigid tube must be very precise so that the tube is able to reach the bottom of the tank without however touching it so as not to damage it. The tube must therefore be of a length less than the inner length of the tank, which will therefore not guarantee its complete emptying.
Enfin, il est difficile de changer de réservoir proprement, puisque du liquide présent sur le tube plongeur risque de goutter.Finally, it is difficult to change the reservoir properly, since the liquid present on the dip tube risks dripping.

L'invention prévoit de remédier à au moins un des inconvénients précités en proposant un nouveau système de distribution de liquide plus fiable que ceux de l'art antérieur.The invention provides for remedying at least one of the aforementioned drawbacks by proposing a new liquid distribution system that is more reliable than those of the prior art.
L'invention a ainsi pour objet un système de distribution d'un liquide conforme à la revendication 1.The subject of the invention is thus a system for distributing a liquid in accordance with
Le réservoir de liquide ne fait pas partie intégrante de l'appareil mais est installé dans celui-ci de manière amovible. Le réservoir possède son propre système de restitution (ou de remontée) de liquide (tube interne d'aspiration ou tube plongeur) qui réagit sous l'action d'une dépression provoquée par le dispositif de pompage et de distribution afin de faire remonter le liquide du fond du réservoir vers le haut de celui-ci. L'aiguille creuse principale ne sert que de première interface pour, d'une part, perforer le réservoir et, d'autre part, permettre au liquide amené du fond du réservoir de sortir de celui-ci et d'être acheminé vers le dispositif de pompage et de distribution. L'aiguille creuse principale n'a pas pour fonction d'aller chercher le liquide au fond du réservoir comme dans l'art antérieur et ne fait donc pas partie du système de restitution de liquide. Ainsi, il n'y a pas à dimensionner de façon très précise une aiguille creuse afin qu'elle puisse aller chercher le liquide au fond du réservoir sans l'endommager, le réservoir étant en effet déjà équipé de son propre système de restitution de liquide.The liquid reservoir is not an integral part of the device but is installed in it removably. The tank has its own liquid return (or rise) system (internal suction tube or dip tube) which reacts under the action of a vacuum caused by the pumping and distribution device in order to bring the liquid back up. from the bottom of the tank to the top of it. The main hollow needle only serves as a first interface to, on the one hand, perforate the reservoir and, on the other hand, allow the liquid brought from the bottom of the reservoir to exit from the latter and be conveyed to the device. pumping and distribution. The main hollow needle does not have the function of fetching the liquid from the bottom of the reservoir as in the prior art and is therefore not part of the liquid return system. Thus, there is no need to size a hollow needle very precisely so that it can pick up the liquid at the bottom of the tank without damaging it, the tank being in fact already equipped with its own liquid return system. .
L'aiguille creuse secondaire sert, quant à elle, de deuxième interface pour, d'une part, perforer le réservoir et, d'autre part, amener de l'air extérieur de compensation à l'intérieur du réservoir (moyen de reprise d'air).The secondary hollow needle serves, for its part, as a second interface for, on the one hand, perforating the reservoir and, on the other hand, bringing the external air of compensation inside the reservoir (return means d 'air).
L'appareil selon l'invention est judicieusement conçu pour que les dites au moins deux aiguilles principale et secondaire servant d'interfaces fluidiques (comme exposé ci-dessus) entre le dispositif de pompage et de distribution et le réservoir soient solidaires d'une pièce intermédiaire de l'appareil qui est distincte dudit dispositif. Ainsi, le dispositif peut être un dispositif conventionnel tel qu'on en trouve dans le commerce et seule la partie de l'appareil comportant la pièce avec les aiguilles est spécifique.The apparatus according to the invention is judiciously designed so that the said at least two main and secondary needles serving as fluidic interfaces (as explained above) between the pumping and distribution device and the reservoir are integral with one part. intermediary of the apparatus which is distinct from said device. Thus, the device can be a device conventional as found in the trade and only the part of the device comprising the part with the needles is specific.
Le dispositif de pompage et de distribution de liquide peut donc être remplacé sans avoir besoin de toucher à la pièce à laquelle sont assujetties lesdites au moins deux aiguilles.The device for pumping and dispensing liquid can therefore be replaced without having to touch the part to which said at least two needles are subject.
L'appareil est donc particulièrement simple de conception et de fabrication puisqu'il ne nécessite pas de concevoir une pompe spécifique.The device is therefore particularly simple to design and manufacture since it does not require the design of a specific pump.
Le dispositif de pompage et de distribution de liquide utilisé dans l'appareil intègre en lui-même son propre système de mise à l'air libre. La configuration de l'appareil est donc simple puisqu'elle utilise la capacité d'étanchéité du système de mise à l'air libre du dispositif de pompage et ne nécessite donc pas un système de mise à l'air libre séparé et indépendant : lorsque le dispositif de pompage n'est pas actionné, le système de mise à l'air libre n'est pas activé et l'air extérieur ne peut pénétrer dans le dispositif et dans l'aiguille secondaire. Au contraire, lorsque le dispositif est actionné, l'air extérieur entre dans le dispositif via le système de mise à l'air libre qui est ouvert et parvient jusqu'à l'aiguille secondaire et donc jusqu'au réservoir avec lequel l'aiguille fait le lien. L'activation du système de mise à l'air libre ne nécessite donc pas une action séparée de la part de l'utilisateur puisqu'elle intervient systématiquement dès lors que l'action de pompage est exercée par l'utilisateur. Simultanément, le liquide est pompé depuis le fond du réservoir par l'extrémité libre du tube plongeur, remonte dans l'aiguille principale qui est reliée au tube et traverse le dispositif de pompage et de distribution pour être distribué à l'extérieur. Dans la configuration de l'appareil, les circuits fluidiques ou chemins pour l'air et le liquide (en sens inverse l'un de l'autre) sont étanches l'un par rapport à l'autre afin de ne pas perturber, voire entraver le fonctionnement du système (les deux circuits ou chemins sont dissociés physiquement afin d'éviter d'aspirer préférentiellement de l'air lors du pompage de liquide). En particulier, l'aiguille secondaire n'est pas en contact avec l'aiguille principale dans le réservoir dans la mesure où ladite aiguille principale est reliée de manière étanche au tube plongeur.The pumping and liquid distribution device used in the device incorporates in itself its own ventilation system. The configuration of the device is therefore simple since it uses the sealing capacity of the venting system of the pumping device and therefore does not require a separate and independent venting system: when the pumping device is not activated, the venting system is not activated and outside air cannot enter the device and the secondary needle. On the contrary, when the device is actuated, the outside air enters the device via the venting system which is open and reaches the secondary needle and therefore the reservoir with which the needle. makes the connection. The activation of the venting system therefore does not require a separate action on the part of the user since it systematically intervenes as soon as the pumping action is exerted by the user. Simultaneously, the liquid is pumped from the bottom of the tank through the free end of the dip tube, rises in the main needle which is connected to the tube and passes through the pumping and dispensing device to be distributed outside. In the configuration of the device, the fluid circuits or paths for air and liquid (in the opposite direction to each other) are sealed with respect to each other so as not to disturb or even hinder the operation of the system (the two circuits or paths are physically separated in order to avoid preferentially sucking in air when pumping liquid). In particular, the secondary needle is not in contact with the main needle in the reservoir insofar as said main needle is tightly connected to the dip tube.
Lorsque le réservoir de liquide est vide, il est retiré de l'appareil et un autre réservoir plein est mis à sa place. L'appareil peut donc être réutilisé un grand nombre de fois sans avoir à jeter l'ensemble du système de distribution et de pompage (appareil et réservoir).When the liquid reservoir is empty, it is removed from the device and another full reservoir is put in its place. The device can therefore be reused a many times without having to throw away the entire distribution and pumping system (device and tank).
Par ailleurs, le montage des aiguilles sur une pièce intermédiaire de l'appareil (formant support d'aiguilles), indépendante du dispositif de pompage et de distribution, permet de fixer les aiguilles de manière plus fiable (par exemple par surmoulage) que sur ledit dispositif. Ainsi, lorsque l'on retire le réservoir de l'appareil pour désengager les aiguilles (à chaque changement de réservoir), les risques de détachement des aiguilles de la pièce formant support au cours du temps sont réduits par rapport à l'appareil de l'art antérieur précité.Moreover, the mounting of the needles on an intermediate part of the device (forming a needle support), independent of the pumping and dispensing device, makes it possible to fix the needles more reliably (for example by overmolding) than on said device. Thus, when the reservoir is removed from the apparatus to disengage the needles (at each change of reservoir), the risks of the needles detaching from the part forming the support over time are reduced compared with the apparatus of the the aforementioned prior art.
L'utilisation d'aiguilles creuses par exemple de type aiguille hypodermique permet d'avoir un réservoir de liquide obturé en permanence (durant le transport et l'utilisation) et qui n'a pas besoin d'être ouvert pour être utilisé. En effet, il suffit d'introduire le réservoir dans l'appareil et de le mettre en place en position d'utilisation en le poussant vers les aiguilles pour que celles-ci perforent le réservoir (plus particulièrement le moyen de bouchage ou de fermeture du réservoir) et que, par actionnement du dispositif de distribution, du liquide puisse être distribué (ex : pulvérisé) et de l'air introduit dans le réservoir.The use of hollow needles, for example of the hypodermic needle type, makes it possible to have a liquid reservoir which is permanently closed (during transport and use) and which does not need to be opened in order to be used. In fact, it suffices to introduce the reservoir into the device and to put it in place in the position of use by pushing it towards the needles so that they perforate the reservoir (more particularly the means of plugging or closing the tank) and that, by actuating the distribution device, liquid can be distributed (eg sprayed) and air introduced into the tank.
Le simple geste de retrait du réservoir vide de l'appareil permet de désengager les aiguilles du réservoir et de remplacer le réservoir vide par un réservoir plein.The simple gesture of removing the empty tank from the device allows you to disengage the needles from the tank and replace the empty tank with a full tank.
L'aiguille principale n'a pas pour but d'aller au fond du réservoir dans la mesure où celui-ci intègre déjà son propre système de restitution de liquide (tube plongeur). De ce fait la longueur de l'aiguille doit être suffisante pour pouvoir perforer le réservoir et pénétrer à l'intérieur sans avoir besoin de s'étendre jusqu'au fond comme dans l'art antérieur. La longueur de l'aiguille principale (tout comme celle de l'aiguille secondaire) est ainsi considérée comme petite par rapport à une dimension principale du réservoir, par exemple par rapport à la longueur ou hauteur du réservoir si celui-ci a une forme générale allongée, par exemple sensiblement cylindrique.The main needle is not intended to go to the bottom of the reservoir insofar as the latter already incorporates its own liquid return system (dip tube). Therefore, the length of the needle must be sufficient to be able to perforate the reservoir and penetrate inside without having to extend to the bottom as in the prior art. The length of the main needle (like that of the secondary needle) is thus considered to be small in relation to a main dimension of the reservoir, for example in relation to the length or height of the reservoir if the latter has a general shape. elongated, for example substantially cylindrical.
Par conséquent, les aiguilles peuvent être bien plus courtes que le tube perforant de l'appareil précité. Il s'ensuit que la course à effectuer par les aiguilles pour sortir du réservoir est bien plus réduite que dans l'art antérieur, ce qui peut rendre plus facile le mouvement de retrait. Par ailleurs, comme ces aiguilles sont courtes, le risque de les casser est moins élevé que dans l'art antérieur. De plus, la partie de l'aiguille principale susceptible de plonger dans le liquide est faible (ou nulle selon l'agencement) si bien que le changement de réservoir peut être réalisé proprement, sans que du liquide ne goutte. Enfin, comme les aiguilles sont courtes, il est possible de prévoir un habillage pour les masquer et éviter à l'utilisateur de se blesser, alors que dans l'état de la technique, il est impossible de réaliser un habillage masquant complètement l'aiguille au risque de ne plus pouvoir accéder au réservoir.Therefore, the needles can be much shorter than the piercing tube of the above apparatus. It follows that the race to be carried out by the needles to exit the reservoir is much smaller than in the prior art, which can make the withdrawal movement easier. Moreover, as these needles are short, the risk of breaking them is lower than in the prior art. In addition, the part of the main needle capable of plunging into the liquid is small (or zero depending on the arrangement) so that the reservoir change can be carried out cleanly, without the liquid dripping. Finally, as the needles are short, it is possible to provide a covering to hide them and prevent the user from injuring himself, whereas in the state of the art, it is impossible to produce a covering completely masking the needle. at the risk of not being able to access the tank.
On notera que les aiguilles peuvent être disposées suivant différentes configurations : côte à côte de manière accolée ou bien distantes l'une de l'autre, centrées ou non par rapport au réservoir, concentriques l'une par rapport à l'autre........ Les aiguilles peuvent également adopter des longueurs différentes l'une par rapport à l'autre, voire des diamètres internes différents. Les aiguilles ont généralement une extrémité perforatrice taillée en biseau comme les aiguilles de type hypodermique.It will be noted that the needles can be arranged in different configurations: side by side in a contiguous manner or well apart from one another, centered or not with respect to the tank, concentric with respect to one another, etc. ..... The needles can also adopt different lengths with respect to each other, or even different internal diameters. The needles usually have a bevel-cut perforator end like the hypodermic type needles.
Le tube plongeur peut être souple (en plastique), ce qui facilite sa mise en place à l'intérieur du réservoir jusqu'au fond de celui-ci. Le tube plongeur souple peut être plus long que la hauteur intérieure du réservoir et, du fait de sa souplesse, il se courbe donc au contact du fond du réservoir, permettant ainsi de garantir la restitution intégrale du liquide. Cette configuration lui permet d'absorber les variations de hauteur qui peuvent exister d'un réservoir à l'autre.The dip tube can be flexible (plastic), which facilitates its installation inside the reservoir to the bottom thereof. The flexible dip tube can be longer than the interior height of the reservoir and, because of its flexibility, it therefore curves in contact with the bottom of the reservoir, thus making it possible to guarantee the full return of the liquid. This configuration allows it to absorb the variations in height that may exist from one tank to another.

Ce bloc comporte une première pièce dite de distribution 18 qui s'étend transversalement suivant la quasi-totalité du diamètre de l'ouverture de l'extrémité supérieure 12a. La pièce 18 est partiellement évidée dans sa partie centrale pour recevoir, par le dessous, une deuxième pièce 20 allongée perpendiculairement suivant l'axe Z. La pièce 18 est munie, dans sa partie périphérique, d'un organe de distribution de liquide 22 (ici, il s'agit d'un organe de pulvérisation) qui débouche sur l'extérieur.

Le bloc inférieur 30 comprend un corps cylindrique 32 ouvert à son extrémité inférieure 32a et fermé à son extrémité supérieure 32b par une paroi transversale 34. Cette paroi 34 est surmontée d'un col creux 36 de diamètre inférieur au diamètre du corps 32 et qui s'étend jusque dans la zone haute située dans la partie de l'enveloppe en forme de tronc de cône.The
Le col 36 définit un logement interne. Une pièce 38 de forme cylindrique formant tourelle s'étend axialement dans le logement interne à partir de la paroi 34 et est surmontée d'une cheminée cylindrique 40.The
L'ensemble formé du corps 32 et du col 36 présente une symétrie axiale par rapport à un axe longitudinal central S (
La pièce 38 est excentrée par rapport à l'axe de symétrie axiale S mais la cheminée 40 est alignée suivant cet axe. La pièce 38 est percée dans sa hauteur ou épaisseur (axe Z) par deux canaux traversants 38a, 38b parallèles. Le canal central 38a est aligné avec l'axe S et la cheminée 40 qui le prolonge vers le haut. Le canal excentré 38b est disposé entre le canal central 38a et la paroi du col 36. Le canal 38a surmonté de la cheminée 40 et le canal 38b mettent chacun en communication l'intérieur du corps 32 avec le logement interne au col 36.The

La pièce 42 est engagée à l'intérieur du logement interne au col 36 et est fixée sur la pièce 38 de manière à ce que la cheminée 40 soit emmanchée à l'intérieur du canal traversant 42b.

La pièce 20 comprend deux parties :
un piston 21 qui est apte à coulisser à l'intérieur de la pièce 42 formant une chemise en comprimant un ressort de rappel 25 logé sous le piston,- une tige creuse 27 comprenant une portion allongée 27a dont l'extrémité supérieure est fixée à la pièce 18 et une portion de diamètre élargi 27b qui est insérée dans le
piston 21 et fixée à ce dernier.
- a
piston 21 which is able to slide inside thepart 42 forming a sleeve by compressing areturn spring 25 housed under the piston, - a
hollow rod 27 comprising an elongate portion 27a, the upper end of which is fixed to thepart 18 and a portion of enlarged diameter 27b which is inserted into thepiston 21 and fixed to the latter.
Le dispositif 14 comprend également un premier système de clapet supérieur 29 (siège 29a et clapet mobile 29b tel qu'une bille) disposé entre le piston et la tige et un deuxième système de clapet inférieur 31 (siège 31a et clapet mobile 31b tel qu'une bille) disposé en partie basse de la chemise 42.The

As shown on
Une aiguille creuse dite secondaire 52 est fixée, par surmoulage, à l'intérieur du canal périphérique 38b du côté de la paroi 34 qui fait face au logement interne au corps 32. A titre de variante non représentée, chaque aiguille 50, 52 peut être emmanchée en force ou collée à l'intérieur de son canal. L'aiguille secondaire 52, ainsi fixée dans la paroi 34 du corps qu'elle traverse, fait saillie dans le logement précité par une extrémité libre perforatrice 52a.A so-called secondary
L'aiguille secondaire 52 met, quant à elle, le logement interne au corps 32 en communication (de manière permanente) avec le logement interne au col 36 et (de manière temporaire) avec l'extérieur de l'appareil (du système), via le système de mise à l'air libre décrit ci-dessus en référence aux
Les aiguilles sont par exemple du type hypodermique et ont par exemple les mêmes longueurs. Toutefois, dans une variante non représentée, leurs longueurs respectives peuvent être différentes d'une aiguille à l'autre. De façon générale, les aiguilles ont des longueurs qui sont bien inférieures à la longueur du corps 32 (et donc de l'appareil) dans la mesure où elles n'ont pas pour fonction d'aller chercher le liquide dans le réservoir mais uniquement de servir d'interfaces fluidiques dans deux circuits fluidiques distincts (pour le liquide et pour l'air extérieur de compensation) et étanches l'un par rapport à l'autre. Comme on le verra plus loin le réservoir comporte en lui-même un système de restitution intégral de liquide qui agit en réponse à une aspiration d'air créée par le dispositif de pompage 14. On notera que les deux aiguilles sont ainsi montées sur une pièce (les aiguilles sont assujetties à la pièce 32) distincte et indépendante du dispositif 14 de pompage et de distribution (pièce 42 et bloc supérieur 16).The needles are for example of the hypodermic type and for example have the same lengths. However, in a variant not shown, their respective lengths may be different from one needle to another. In general, the needles have lengths which are much less than the length of the body 32 (and therefore of the device) insofar as their function is not to fetch the liquid from the reservoir but only to serve as fluidic interfaces in two separate fluidic circuits (for the liquid and for the external compensation air) and sealed with respect to each other. As will be seen below, the reservoir itself comprises an integral liquid return system which acts in response to a suction of air created by the
Le bloc supérieur 16 est mobile axialement le long de l'axe Z par rapport au bloc inférieur fixe 30 lorsqu'un utilisateur exerce une pression sur la coiffe 23. Plus particulièrement, comme déjà mentionné ci-dessus en référence à la
Le corps 32 est pourvu sur sa surface externe d'une collerette 60 disposée sensiblement à mi-hauteur et qui vient en contact avec la surface interne de l'enveloppe 12.The
Une lumière 62 (
Des évidements longitudinaux 64, 66, 68 sont aménagés sur la surface interne du corps 32, sur une partie de l'épaisseur de la paroi cylindrique dudit corps. Ces évidements sont espacés angulairement l'un de l'autre et s'étendent à partir de l'extrémité libre inférieure 32a du corps sur une hauteur inférieure à la hauteur à laquelle est disposée la collerette 60. Les évidements sont ouverts chacun à leur extrémité inférieure 64a, 66a, 68a afin de pouvoir y introduire par le dessous une pièce de forme complémentaire à celle de l'évidement. Les évidements sont fermés à leur extrémité supérieure par un rebord 64b, 66b, 68b.
L'appareil A comporte également une pièce formant fourreau 70 (
La pièce 70, appelée ci-après fourreau, a une forme légèrement tronconique avec une partie inférieure de diamètre légèrement supérieur à celui de la partie supérieure. La pièce 70 est ouverte à ses deux extrémités opposées 70a, 70b et comporte, à son extrémité supérieure 70a, une collerette interne 71 qui réduit le diamètre de l'ouverture.The
Dans sa partie inférieure le fourreau 70 présente plusieurs découpes longitudinales distribuées radialement suivant la circonférence de manière à former des pattes présentant une élasticité radiale. La paroi du fourreau dans sa partie inférieure comporte ainsi plusieurs pattes élastiques, par exemple trois 72, 74, 76, qui s'étendent à partir de la mi-hauteur du fourreau jusqu'à l'extrémité libre inférieure 70b et qui sont espacées les unes des autres angulairement par des portions de paroi cylindriques rigides 78, 80, 82. Les portions de paroi rigides sont pourvues à leur extrémité libre d'un rebord périphérique externe 78a, 80a, 82a. La distribution angulaire des pattes correspond à celle des évidements 64, 66, 68 du corps 32 dans la mesure où les pattes sont destinées à s'engager dans les évidements lorsque le fourreau est introduit à l'intérieur du corps (
Les pattes élastiques 72, 74, 76, sont munies sur au moins une partie de leur surface interne, notamment dans leur partie basse, d'un revêtement adhérent 84, 86, 88 sous la forme d'un patin d'adhérence par exemple en caoutchouc. En pratique, le patin d'adhérence s'étend sur la surface interne de chaque patte sous la forme d'une bande qui part à mi-hauteur de la patte jusqu'à l'extrémité libre de la patte et forme un retour vers l'extérieur en passant sous ladite extrémité libre. Les patins sont par exemple surmoulés sur les pattes et le retour du patin est utilisé pour le démoulage. Les patins pourraient toutefois être collés ou encliquetés sur les pattes.The
Une fenêtre 90 par exemple rectangulaire est découpée dans la paroi cylindrique du fourreau (sous la collerette 71). Une première patte allongée 92 s'étend, à partir d'un décroché pratiqué dans la collerette 71, axialement à l'intérieur de cette fenêtre (sur une partie de sa hauteur) et est munie à son extrémité libre d'un retour ou ergot 92a dirigé vers l'extérieur. La patte 92 ainsi conformée est disposée parallèlement à la paroi cylindrique du fourreau et présente une élasticité radiale.A
Une deuxième patte allongée 94, de même longueur que la première patte 92, s'étend, à partir de la collerette 71, à l'intérieur de la fenêtre 90 (sur une partie de sa hauteur), immédiatement à côté de la première patte 92. La deuxième patte 94 est munie à son extrémité libre d'un retour ou ergot 94a dirigé vers l'extérieur. La deuxième patte n'est pas disposée parallèlement à la paroi cylindrique du fourreau mais est inclinée par rapport à celle-ci. L'extrémité libre de la deuxième patte 94 fait saillie hors de la fenêtre 90 en position de repos (

Le réservoir R illustré sur la
Le réservoir comporte une pièce formant insert 102 engagée à l'intérieur du passage délimité par le col et qui y est maintenue en position. Le moyen de bouchage 104 (pièce d'obturation) du réservoir vient coiffer l'insert 102 afin d'assurer l'étanchéité du réservoir. Le moyen de bouchage est configuré pour être apte à être perforé par les aiguilles 50 et 52 de l'appareil. Le moyen de bouchage est par exemple réalisé dans un matériau qui est perforable par aiguilles 50 et 52. Ce matériau peut être apte ou non à se refermer après retrait des aiguilles. Le moyen de bouchage est par exemple une membrane qui présente une épaisseur suffisante pour que, lorsque les aiguilles sont retirées, le moyen de bouchage se referme et assure ainsi l'étanchéité. L'épaisseur ne doit toutefois pas être trop élevée afin de pouvoir être perforée facilement par les aiguilles. L'épaisseur varie notamment en fonction de la nature du matériau et des diamètres des aiguilles. Par exemple, l'épaisseur peut varier de 1 à 5mm.The reservoir comprises a part forming an
Le matériau constitutif du moyen de bouchage est par exemple réalisé en élastomère (ex : caoutchouc). Toutefois, le matériau pourrait être en thermoplastique, en silicone, en mousse...The material constituting the closure means is for example made of elastomer (eg rubber). However, the material could be thermoplastic, silicone, foam ...
Plus particulièrement, l'insert 102 comprend un corps de forme générale cylindrique qui est inséré dans le passage du col et comprend :
- une chambre ou cavité centrale 106 cylindrique munie en partie basse d'un orifice 106a communiquant avec l'extrémité supérieure 108a d'un tube souple d'aspiration de liquide ou tube plongeur 108 (
ce tube plongeur 108 s'étend jusqu'au fond du réservoir comme illustré sur lafigure 1 et son extrémité supérieure 108a est introduite en force dans une excroissance cylindrique creuse 109 solidaire du fond de l'insert ; le tube étant souple et plus long que la longueur interne axiale du réservoir, il se courbe à son extrémité inférieure 108b pour venir au contact du fond, ce qui permet de vider intégralement le réservoir de son liquide), - une chambre ou cavité périphérique 110 de forme annulaire, coaxiale à la cavité centrale et qui est munie en partie basse d'un orifice 110a communiquant, avec la partie haute du réservoir.

cavity 106 provided at the bottom with anorifice 106a communicating with theupper end 108a of a flexible liquid suction tube or dip tube 108 (thisdip tube 108 extends to the bottom of the tank as shown onfigure 1 and itsupper end 108a is forcefully introduced into a hollowcylindrical protuberance 109 integral with the bottom of the insert; the tube being flexible and longer than the axial internal length of the reservoir, it curves at itslower end 108b to come into contact with the bottom, which makes it possible to completely empty the reservoir of its liquid), - a peripheral chamber or
cavity 110 of annular shape, coaxial with the central cavity and which is provided in the lower part with anorifice 110a communicating with the upper part of the reservoir.
Les deux cavités ou chambres 106 et 110 sont isolées l'une de l'autre.The two cavities or
Comme représenté sur la
L'insert 102 comporte en partie haute du corps une extension périphérique formant un épaulement 102a. Une rondelle 112 est disposée sur le bord libre supérieur du col 100 et l'épaulement 102a s'appuie sur cette rondelle. Cette rondelle est un joint d'étanchéité.The
La cavité centrale 106 de l'insert 102 est délimitée par une portion cylindrique centrale 102b qui est plus haute que le reste du corps et notamment que l'épaulement 102a. Cette différence de hauteur permet de réaliser une étanchéité tubulaire entre les deux cavités 106 et 110. L'isolation fiable entre les deux cavités est ainsi plus simple à obtenir qu'en essayant de réaliser une étanchéité plane.The
La pièce de bouchage ou d'obturation 104 en élastomère est conformée sur sa face inférieure de manière à s'emboîter dans la partie supérieure de l'insert 102 et, notamment, sur l'extrémité libre de la portion cylindrique centrale 102b ainsi que dans une gorge annulaire 102c de l'épaulement 102a.The elastomeric plugging or sealing
La pièce d'obturation 104 a plus particulièrement une partie centrale 104a en forme de disque qui est creusé dans sa face inférieure pour y loger la partie supérieure 102b de l'insert. Une collerette périphérique 104b entoure la partie centrale 104a dans sa partie basse et est pourvue, sur sa face inférieure, d'un rebord annulaire qui s'étend axialement vers le bas afin de s'engager dans la gorge annulaire 102c.The
On notera que dans une variante non représentée la pièce d'obturation et la pièce formant insert font partie d'une seule et même pièce.It will be noted that in a variant not shown, the closure part and the part forming an insert form part of one and the same part.
Le réservoir R comporte une pièce annulaire de serrage 114 qui a une forme générale cylindrique 114a entourant, d'une part, le col 100 et, d'autre part, l'empilement constitué de la rondelle 112, de l'épaulement 102a et de la collerette 104b. La partie basse 114b de la pièce 114 est amenée, par sertissage, en appui sous un épaulement externe du col 100. La pièce 114 forme en partie haute un retour interne 114c dirigé vers la partie centrale 104a et qui s'étend au-dessus de l'épaulement 102a et de la collerette 104b. La pièce 114 forme une capsule de sertissageThe reservoir R comprises an
Le retour interne 114c est incliné vers le bas en direction de la collerette 104b de manière à presser fermement ladite collerette.The
La pièce de serrage 114 enserre ainsi l'ensemble formé par le col 100 et l'empilement de la rondelle 112, de l'épaulement 102a et de la collerette 104b.The
Le réservoir R comporte, autour de l'ensemble des éléments précités, une pièce 116 ayant une forme de virole 116a. La virole 116a comporte à sa partie supérieure un rebord intérieur 116b s'étendant perpendiculairement à la virole en direction de la partie centrale 104a.The reservoir R comprises, around all of the aforementioned elements, a
Le bord intérieur libre du rebord 116b est recourbé vers le bas contre la collerette 104b de manière à emprisonner et masquer l'assemblage formé des éléments 112, 102a, 114 et 104b.The free inner edge of the
Le réservoir qui vient d'être décrit (après avoir été rempli de liquide et bouché) est apte à être introduit dans l'appareil des figures la à 5 pour être perforé par les aiguilles 50 et 52 de la figure la.The reservoir which has just been described (after having been filled with liquid and stoppered) is suitable for being introduced into the apparatus of FIGS. La to 5 in order to be perforated by
En l'absence du réservoir dans l'appareil le fourreau 70 est dans une position dite basse illustrée en pointillés sur la figure la et repérée par la référence 70(B).In the absence of the reservoir in the apparatus, the
Lorsqu'un réservoir R doit être chargé dans l'appareil, l'utilisateur l'introduit axialement à l'intérieur de l'enveloppe 12 (suivant l'axe longitudinal Z) par l'extrémité 12b.When a reservoir R must be loaded into the device, the user introduces it axially inside the casing 12 (along the longitudinal axis Z) through the
Le réservoir R est inséré partiellement à l'intérieur du logement axial délimité par le fourreau situé en position basse 70(B) jusqu'à venir en butée contre la face interne de la collerette 71 du fourreau et adopte la position illustrée sur la
Dans cette position (
Les portions d'adhérence aménagées sur les pattes élastiques 72, 74, 76 du fourreau jouent leur rôle en adhérant à la surface externe du réservoir, bloquant ainsi le réservoir axialement afin d'empêcher sa descente lorsqu'il est engagé dans le fourreau en position d'utilisation.The grip portions provided on the
Lorsque l'utilisateur pousse davantage le réservoir ou cartouche R vers le haut suivant la flèche de la
Lors de ce mouvement l'ergot ou élément saillant 94a est guidé dans la lumière 62 par la forme de rampe de celle-ci (chemin de came) le long des première et deuxième portions 62a, 62b et se déforme latéralement en direction de la patte 92 pour suivre la rampe.During this movement, the lug or projecting element 94a is guided in the light 62 by the ramp shape of the latter (cam track) along the first and
Sous la poussée, l'ensemble constitué du fourreau et du réservoir pénètre davantage à l'intérieur du corps 32 jusqu'à ce que les aiguilles 50 et 52 (non représentées sur les
Simultanément, l'ergot 94a déformé latéralement de manière élastique atteint la cote axiale du décroché 62c.Simultaneously, the lug 94a elastically deformed laterally reaches the axial dimension of the
N'étant plus forcé à se déformer latéralement par la rampe, l'ergot 94a est rappelé élastiquement en direction de sa position non déformée et s'engage dans le décroché 62c qui forme un élément de retenue de l'ergot du fourreau. Toutefois, l'ergot 94a ne peut revenir complètement à sa position non déformée de la
Le fourreau 70 est ainsi bloqué ou verrouillé en position haute qui est repérée par la référence 70 (H) sur la
L'appareil A est alors prêt à être utilisé dans la position d'utilisation illustrée sur la figure la.The apparatus A is then ready for use in the position of use illustrated in FIG.
La description qui va suivre du fonctionnement du système en vue de distribuer du liquide est faite en relation avec le dispositif de pompage et de distribution 14 de la figure la par souci de simplicité. Toutefois, il sera fait référence aux
Des appuis verticaux successifs d'un utilisateur sur le bloc mobile supérieur 16 permettent de faire coulisser la deuxième pièce 20 dans la cavité centrale 42c et, en remontant, de créer une aspiration de liquide (pompage) du réservoir à l'orifice de distribution de l'organe 22. Cette remontée de liquide est effectuée par l'intermédiaire, successivement, du tube plongeur 108, de la cavité centrale 106, de l'aiguille principale 50, de la cheminée 40, du canal 42b, de la cavité 42d, du canal 20a et des canaux internes à la première pièce 18 (dispositif 14). On notera que le tube plongeur souple 108 forme le système de restitution intégrale de liquide du réservoir (appelé également système de contrôle du taux de restitution) qui, sous l'action du dispositif de pompage 14, assure la remontée du liquide depuis le fond du réservoir.Successive vertical supports by a user on the upper
L'aiguille principale 50 forme ainsi une première interface de communication pour le liquide entre le tube plongeur 108 du réservoir (via la chambre 106 dans ce mode réalisation) et le dispositif 14, lorsque ce dernier est actionné pour pomper du liquide, afin d'établir un premier circuit fluidique pour le liquide, depuis l'extrémité inférieure 108b du tube plongeur touchant le fond du réservoir jusqu'à l'organe 22.The
L'aiguille secondaire 52 assure concomitamment une entrée d'air dans le réservoir lors du pompage du liquide afin de compenser le volume de liquide pompé. L'aiguille secondaire 52 forme ainsi une deuxième interface de communication pour l'air extérieur de compensation entre le système de mise à l'air libre du dispositif 14 (sur la
Ainsi conçus les deux circuits ou chemins fluidiques sont séparés et étanches l'un par rapport à l'autre. En particulier, l'extrémité perforante de l'aiguille secondaire 52 par laquelle l'air extérieur pénètre dans le réservoir débouche dans une zone supérieure éloignée de la zone inférieure dans laquelle est pompé le liquide. Le liquide pompé circule dans le tube plongeur, la cavité 106, l'aiguille principale 50 et la pièce 42 qui sont montées de manière étanche l'un par rapport à l'autre, empêchant ainsi toute rencontre entre l'air et le liquide.Thus designed, the two circuits or fluidic paths are separated and sealed from one another. In particular, the perforating end of the
On notera que lors de l'utilisation du dispositif de pompage on n'exerce pas d'effort sur le réservoir. En effet, ceci est rendu possible par la structure de l'appareil dans laquelle le dispositif de pompage est en appui sur une partie (haute) du bloc inférieur 30 fixe tandis que le réservoir sollicite pour son insertion, par l'intermédiaire du fourreau, une autre partie (basse) du bloc 30. De même, lors de l'insertion du réservoir il n'y a aucune poussée exercée sur le dispositif de pompage. Cette structure d'appareil permet d'avoir une cartouche ou recharge de conception simple qui ne nécessite notamment pas de système d'accrochage mécanique/blocage entre la recharge et le dispositif de pompage.It will be noted that when using the pumping device, no force is exerted on the reservoir. Indeed, this is made possible by the structure of the apparatus in which the pumping device is supported on a (upper) part of the fixed
Le réservoir R est retiré lorsque la totalité (ou presque) du liquide a été consommée ou bien pour d'autres raisons (ex. : souhait de l'utilisateur de changer de parfum). Pour ce faire, il suffit d'appuyer sur le fond du réservoir comme indiqué par la flèche de la
Dans la mesure où la partie supérieure de l'ergot 94a est biseautée le mouvement imposé au fourreau permet à l'ergot 94a de se déformer radialement vers l'arrière au contact avec le bord supérieur du décroché 62c et, ainsi, de sortir dudit décroché (
Dans cette position il entre alors en contact avec l'ergot 92a de la première patte 92, comme indiqué plus haut lors de la description de l'agencement et des formes respectives complémentaires des deux ergots.In this position, it then comes into contact with the
La deuxième patte 94 qui n'est alors plus contrainte latéralement par le décroché 62c en direction de la patte 92 est alors ramenée latéralement de façon élastique dans une position parallèle à celle de la première patte 92 comme illustré sur la
La patte 94 est toutefois toujours contrainte radialement par la paroi du corps 32 tant que la descente du fourreau se poursuit et jusqu'à atteindre la portion 62a de la lumière 62. L'ergot 94a s'y engage alors naturellement de façon élastique pour revenir à sa forme non déformée de la
Le réservoir peut alors être simplement retiré par l'utilisateur en tirant avec les doigts sur l'extrémité débouchante. L'aiguille principale ne trempant pas dans le liquide, le retrait du réservoir peut être effectué plus proprement que dans l'art antérieur.The reservoir can then be simply removed by the user by pulling with the fingers on the open end. Since the main needle does not soak in the liquid, the withdrawal of the reservoir can be carried out more cleanly than in the prior art.
On notera que la mise en place d'un réservoir de liquide R dans l'appareil A jusqu'à sa position d'utilisation et son retrait sont particulièrement simples à réaliser pour un utilisateur.It will be noted that the placing of a reservoir of liquid R in the device A up to its position of use and its removal are particularly simple to carry out for a user.
Le réservoir de liquide n'a pas besoin d'être ouvert par l'utilisateur pour avoir accès au liquide.The liquid reservoir does not need to be opened by the user to gain access to the liquid.
L'appareil est simple et fiable de conception.The device is simple and reliable in design.
Les aiguilles 50 et 52 sont inaccessibles de l'extérieur de l'appareil car elles sont protégées par l'enveloppe 12 et le corps 32.The
Plus particulièrement, les aiguilles sont disposées au fond du logement interne du corps allongé 32 qui est lui-même disposé en retrait de l'ouverture de l'extrémité ouverte inférieure 12b de l'enveloppe.More particularly, the needles are arranged at the bottom of the internal housing of the
Même en l'absence de réservoir, les doigts d'un utilisateur ne peuvent entrer en contact avec les aiguilles.Even in the absence of a reservoir, a user's fingers cannot come into contact with the needles.
