Description

Distributeur de produit fluide Fluid dispenser
La présente invention concerne un distributeur de produit fluide comprenant un réservoir de produit fluide et un organe de distribution sous la forme d'une membrane vibrante. En général, la membrane vibrante est perforée d'un ou de plusieurs trous de distribution à travers lesquels le produit fluide est distribué sous l'effet de la vibration de la membrane. Pour faire vibrer cette membrane perforée, il est en général prévu des moyens de vibration : un élément piezo électrique peut constituer de bons moyens de vibration pour faire vibrer la membrane. La présente invention concerne plus particulièrement le domaine de la cosmétique, de la parfumerie ou encore de la pharmacie. Le distributeur présente par conséquent une taille relativement réduite susceptible d'être saisi à l'aide d'une main de l'utilisateur. L'utilisateur devra en outre pouvoir actionner le distributeur à l'aide d'une seule main en appuyant sur un bouton d'actionnement destiné à activer les moyens de vibration de la membrane.The present invention relates to a fluid dispenser comprising a fluid reservoir and a dispensing member in the form of a vibrating membrane. In general, the vibrating membrane is perforated with one or more dispensing holes through which the fluid is distributed under the effect of the vibration of the membrane. In order to vibrate this perforated membrane, vibration means are generally provided: a piezoelectric element can constitute good vibration means for vibrating the membrane. The present invention relates more particularly to the field of cosmetics, perfumery or even pharmacy. The dispenser therefore has a relatively small size capable of being grasped with the hand of the user. The user must also be able to actuate the dispenser with one hand by pressing an actuation button intended to activate the vibration means of the membrane.
Dans une pompe classique qui marche par aspiration et refoulement, la pression qui règne à l'intérieur du réservoir n'influe pas directement sur le fonctionnement de la pompe. En effet, une pompe classique peut fonctionner avec un réservoir sous pression ou en dépression, à condition de ne pas atteindre des valeurs extrêmes. Ceci n'est pas le cas avec une membrane vibrante perforée qui ne dispose pas de clapet d'entrée ni de sortie. Par conséquent, le produit fluide doit être alimenté à la membrane vibrante avec une pression sensiblement égale à la pression atmosphérique. Une très légère dépression ou une très légère surpression est cependant acceptable. En effet, si le réservoir est sous pression, du produit fluide peut fuir à travers les trous de la membrane perforée, ce qui résulterait en des suintements inacceptables. A l'inverse, une dépression à l'intérieur du réservoir entraînerait une pénétration d'air dans le distributeur à travers les trous de la membrane perforée. En outre, la pulvérisation serait de très mauvaise qualité. Dans les documents EP 0 615 470 et EP 0 696 234, il est décrit des distributeurs de produit fluide comprenant un réservoir et une membrane perforée mais en vibration à l'aide d'un élément piezo-électrique. Pour alimenter la membrane perforée depuis le réservoir, il est prévu des moyens d'alimentation en fluide qui font la liaison entre le réservoir et la membrane. Etant donné que la membrane perforée est située au-dessus du réservoir en condition normale d'utilisation, il est nécessaire de faire monter le produit fluide à encontre de la gravité. Pour cela, les moyens d'alimentation sont des conduits capillaires dans lesquels le produit fluide monte naturellement jusqu'en contact de la membrane perforée.In a conventional pump which works by suction and discharge, the pressure which prevails inside the tank does not directly influence the operation of the pump. Indeed, a conventional pump can operate with a tank under pressure or under vacuum, provided that it does not reach extreme values. This is not the case with a perforated vibrating membrane which does not have an inlet or outlet valve. Consequently, the fluid product must be supplied to the vibrating membrane with a pressure substantially equal to atmospheric pressure. A very slight depression or a very slight overpressure is however acceptable. Indeed, if the tank is under pressure, fluid can leak through the holes in the perforated membrane, which would result in unacceptable seepage. Conversely, a vacuum inside the tank would cause air to enter the distributor through the holes in the perforated membrane. In addition, the spray would be of very poor quality. In documents EP 0 615 470 and EP 0 696 234, there are described fluid dispensers comprising a reservoir and a membrane perforated but vibrating using a piezoelectric element. To supply the perforated membrane from the reservoir, fluid supply means are provided which make the connection between the reservoir and the membrane. Since the perforated membrane is located above the tank under normal conditions of use, it is necessary to raise the fluid against gravity. For this, the supply means are capillary conduits in which the fluid product rises naturally up to contact with the perforated membrane.
Cependant, il n'est pas toujours aisé de contrôler l'alimentation du fait qu'elle est réalisée par capillarité.However, it is not always easy to control the feeding because it is carried out by capillary action.
Par conséquent, la présente invention se propose de remédier aux inconvénients précités de l'art antérieur provenant de la capillarité en définissant un autre type d'alimentation de produit fluide depuis le réservoir jusqu'à la membrane vibrante. Les documents US-4 882 096 et JP-04 236962 décrivent des distributeurs à membrane perforée vibrante qui sont alimentées par gravité. Toutefois, ce type de distributeurs est sujet à des fuites au niveau de la membrane perforée en raison de la pression exercée par la colonne de fluide formée par le réservoir situé au-dessus. Pour résoudre ce problème, il est prévu que le réservoir, en condition normale d'utilisation, est situé au-dessus de la membrane perforée de sorte que le produit fluide est alimenté par gravité à la membrane depuis le réservoir, et que la membrane est reliée au réservoir par un passage pourvu d'un clapet d'admission apte à ouvrir et couper sélectivement le passage. Ainsi, l'alimentation de la membrane n'est plus dépendante d'un phénomène physique particulier (capillarité) qui induit un caractère aléatoire. Grâce à la gravité, la membrane est assurément et directement alimentée en produit fluide avec une pression sensiblement égale à la pression atmosphérique. L'expression « en condition normale d'utilisation » signifie la période d'actionnement du bouton pour activer les moyens de vibration. En d'autre terme, l'invention prévoit que le réservoir est situé au-dessus de la membrane lorsque l'on appuie sur le bouton d'actionnement.Consequently, the present invention proposes to remedy the aforementioned drawbacks of the prior art originating from capillary action by defining another type of supply of fluid product from the reservoir to the vibrating membrane. Documents US-4 882 096 and JP-04 236962 describe distributors with vibrating perforated membranes which are fed by gravity. However, this type of dispenser is subject to leaks at the perforated membrane due to the pressure exerted by the column of fluid formed by the reservoir located above. To solve this problem, it is provided that the reservoir, under normal conditions of use, is situated above the perforated membrane so that the fluid product is fed by gravity to the membrane from the reservoir, and that the membrane is connected to the tank by a passage provided with an intake valve able to selectively open and cut the passage. Thus, the supply of the membrane is no longer dependent on a particular physical phenomenon (capillarity) which induces a random character. Thanks to gravity, the membrane is assured and directly supplied with fluid product with a pressure substantially equal to atmospheric pressure. The expression “in normal condition of use” means the period of actuation of the button to activate the vibration means. In other words, the invention provides that the tank is located above the membrane when the actuation button is pressed.
De préférence, les moyens de vibration et le clapet d'admission sont commandés électriquement. Grâce à ce clapet d'admission, il est possible d'isoler la membrane du réservoir de sorte qu'elle n'est soumise à aucune pression. On évite ainsi tout risque de fuite ou de suintement de produit fluide au travers des trous de la membrane perforée. Avantageusement, le clapet d'admission ne s'ouvre que lors des périodes d'actionnement du distributeur, c'est à dire lorsque l'on appuie sur le bouton d'actionnement. Par exemple, le bouton d'actionnement peut commander simultanément l'activation des moyens de vibration et l'ouverture du clapet d'admission. Ainsi, la membrane perforée n'est alimentée en produit fluide que lors des périodes d'actionnement du distributeur.Preferably, the vibration means and the intake valve are electrically controlled. Thanks to this inlet valve, it is possible to isolate the membrane from the tank so that it is not subjected to any pressure. This avoids any risk of leakage or seepage of fluid through the holes in the perforated membrane. Advantageously, the intake valve opens only during periods of actuation of the dispenser, that is to say when the actuation button is pressed. For example, the actuation button can simultaneously control the activation of the vibration means and the opening of the intake valve. Thus, the perforated membrane is supplied with fluid only during periods of actuation of the dispenser.
Avantageusement, le distributeur comprend un fond destiné à venir en contact de repos avec une surface sensiblement horizontale, le réservoir étant alors situé au-dessus de la membrane vibrante.Advantageously, the dispenser comprises a bottom intended to come into rest contact with a substantially horizontal surface, the reservoir then being located above the vibrating membrane.
Selon une autre caractéristique de l'invention, le réservoir comprend une partie supérieure pourvue d'un passage d'éventation. Avantageusement, le passage d'éventation comprend un élément de matière poreuse. Grâce au passage d'éventation, on assure que le produit fluide à l'intérieur du réservoir est toujours à une pression sensiblement égale à la pression atmosphérique. De plus, en plaçant ce passage au sommet du distributeur, on évite toute fuite de produit fluide à travers le passage. Ces caractéristiques liées à l'éventation peuvent être mises en œuvre dans un distributeur à membrane perforée vibrante alimentée par gravité dépourvu de clapet d'admission. Selon une autre caractéristique, le bouton d'actionnement est situé au niveau de la partie supérieure du réservoir, le passage d'éventation étant formé autour du bouton d'actionnement. On peut également dire que le passage d'éventation est formé entre le bouton d'actionnement et la partie supérieure du réservoir. Avantageusement, le bouton d'actionnement masque l'élément de matière poreuse. On se sert donc du bouton d'actionnement pour réaliser et masquer le passage d'éventation. Un tel bouton d'actionnement à éventation incorporé peut être mis en œuvre sur un distributeur à membrane alimenté par gravité, mais dépourvu de clapet d'admission.According to another characteristic of the invention, the reservoir comprises an upper part provided with a venting passage. Advantageously, the venting passage comprises an element of porous material. Thanks to the venting passage, it is ensured that the fluid inside the reservoir is always at a pressure substantially equal to atmospheric pressure. In addition, by placing this passage at the top of the dispenser, any leakage of fluid is avoided through the passage. These venting-related characteristics can be implemented in a distributor with a vibrating perforated membrane fed by gravity without an inlet valve. According to another characteristic, the actuation button is located at the top of the tank, the venting passage being formed around the actuation button. We can also say that the venting passage is formed between the actuation button and the upper part of the tank. Advantageously, the actuation button masks the element of porous material. We therefore use the actuation button to make and hide the vent passage. Such a vented actuation button incorporated can be implemented on a diaphragm distributor fed by gravity, but without an inlet valve.
L'invention sera maintenant plus amplement décrite en référence au dessin joint donnant à titre d'exemple non limitatif un mode de réalisation de l'invention. La figure unique est une coupe transversale verticale à travers un distributeur de produit fluide selon l'invention.The invention will now be described more fully with reference to the accompanying drawing, which gives an embodiment of the invention by way of non-limiting example. The single figure is a vertical cross section through a fluid dispenser according to the invention.
Le distributeur comprend une embase 1 sur laquelle est monté un réservoir 2.The distributor comprises a base 1 on which a reservoir 2 is mounted.
L'embase 1 forme une coque en deux parties 10 et 12 reliées ensemble sur leur périphérie par un système d'encliquetage 13. L'embase 1 peut présenter une forme quelconque en section transversale horizontale, par exemple circulaire, elliptique ou polygonale. Dans sa section verticale, l'embase est relativement plate et comprend, au niveau de sa partie de coque inférieure 10, un fond 11 sur lequel le distributeur peut reposer naturellement de manière stable. L'embase 1 comprend une ouverture 14 dans laquelle est logée une membrane vibrante 3. Cette ouverture 14 peut être située sur la ligne de jonction de la partie de coque inférieure 10 avec la partie de coque supérieure 12. En outre, la partie de coque supérieure 12 définit une grande ouverture dans laquelle est disposé le réservoir 2. Pour maintenir le réservoir 2 dans l'ouverture, la partie de coque supérieure 12 est formée avec un bord de retenue 15 apte à maintenir fixement le réservoir 2 sur l'embase 1.The base 1 forms a shell in two parts 10 and 12 connected together on their periphery by a latching system 13. The base 1 can have any shape in horizontal cross section, for example circular, elliptical or polygonal. In its vertical section, the base is relatively flat and comprises, at its lower shell part 10, a bottom 11 on which the dispenser can rest naturally in a stable manner. The base 1 comprises an opening 14 in which a vibrating membrane 3 is housed. This opening 14 can be located on the junction line of the lower shell part 10 with the upper shell part 12. In addition, the shell part upper 12 defines a large opening in which the tank 2 is disposed. To keep the tank 2 in the opening, the upper shell part 12 is formed with a retaining edge 15 capable of fixedly holding the tank 2 on the base 1 .
D'autre part, l'embase 1 contient un clapet d'admission 4, un électroaimant 5, une ou plusieurs piles 6 ainsi qu'un système électronique de commande 7. Le réservoir 2 comprend un fond 22 et un dôme 20 reliés ensemble au niveau de leur périphérie respective 24 et 25 avec un joint 26 éventuellement interposé pour assurer l'étanchéité. Le réservoir 2 ainsi formé est maintenu fixement dans la partie supérieure de coque 12 au niveau de leurs périphéries 24, 25. Le dôme 20 comprend une partie supérieure 21 qui définit le sommet du dôme. Selon l'invention, la partie supérieure 21 est pourvue d'une ouverture 210 définie par un petit manchon 211. Un élément de matière poreuse 91 est inséré dans le petit manchon 211 et obture ainsi le passage, tout en laissant passer l'air. Il est ainsi créé un passage d'éventation par lequel de l'air extérieur peut pénétrer à l'intérieur du réservoir à mesure que du produit fluide est distribué à travers la membrane perforée 3. Selon une autre caractéristique de l'invention, un bouton d'actionnement 9 est également prévu au niveau de l'ouverture 210 de la partie supérieure 21 du dôme 20. Ce bouton d'actionnement 9 peut se présenter sous la forme d'un contacteur tactile. Ce bouton 9 est situé juste au-dessus de l'élément de matière poreuse 91 en définissant entre lui et le petit manchon 211 un passage d'éventation 92 qui permet à l'air extérieur de venir en contact de l'élément de matière poreuse 91. Ainsi, le passage d'éventation est formé autour du bouton 9 et masque en outre l'élément de matière poreuse 91. Il est à noter que le bouton 9 est idéalement placé de manière opposée au fond 11 par lequel le distributeur peut reposer sur une surface sensiblement horizontale.On the other hand, the base 1 contains an intake valve 4, an electromagnet 5, one or more batteries 6 as well as an electronic control system 7. The tank 2 comprises a bottom 22 and a dome 20 connected together to the level of their respective peripheries 24 and 25 with a seal 26 possibly interposed to ensure sealing. The reservoir 2 thus formed is fixedly held in the upper shell part 12 at their peripheries 24, 25. The dome 20 comprises an upper part 21 which defines the top of the dome. According to the invention, the upper part 21 is provided with an opening 210 defined by a small sleeve 211. An element of porous material 91 is inserted in the small sleeve 211 and thus blocks the passage, while letting the air pass. There is thus created a vent passage through which outside air can penetrate inside the tank as fluid is distributed through the perforated membrane 3. According to another characteristic of the invention, a button actuation 9 is also provided at the opening 210 of the upper part 21 of the dome 20. This actuation button 9 may be in the form of a touch switch. This button 9 is located just above the element of porous material 91 by defining between it and the small sleeve 211 a vent passage 92 which allows outside air to come into contact with the element of porous material 91. Thus, the venting passage is formed around the button 9 and further masks the element of porous material 91. It should be noted that the button 9 is ideally placed opposite the bottom 11 by which the dispenser can rest on a substantially horizontal surface.
D'autre part, le bouton 9 qui peut être un contacteur électrique est relié par une ligne d'alimentation 8 sous la forme d'une piste plate, au système électronique de commande 7. La ligne d'alimentation 8 peut par exemple courir le long du dôme 20 et pénétrer dans l'embase 1 au niveau du bord de retenue 15. Ainsi, en appuyant sur le bouton 9 le circuit électrique est fermé et le système électronique de commande est alimenté. Le fond 22 du réservoir 2 définit une ouverture de sortie 23 qui se prolonge par un passage d'alimentation en produit fluide 27 qui définit juste en aval de l'ouverture 23 une première section de passage 271 qui est dirigée vers le bas. Cette première section de passage 271 est définie par une tubulure 230 formée par le fond 22 du réservoir. Cette tubulure 230 sert également de raccordement à un corps de clapet 40 qui définit un manchon de raccordement 46 sur la tubulure 230. Au-delà de la première section de passage 271, le corps de clapet 40 définit une seconde section de passage 272 au niveau de laquelle est formé un clapet d'admission 4. Ce clapet d'admission 4 est un clapet électromagnétique comprenant un noyau ferromagnétique 41 situé dans la seconde section de passage 272 qui est obturée à une extrémité par un bouchon 45. L' électroaimant 5 est situé juste derrière le bouchon 45 de sorte qu'il peut induire un champ électromagnétique jusqu'au niveau du noyau ferromagnétique 41. D'autre part, une bille de clapet 43, en acier par exemple, est plaqué sur un siège 44 formé par le corps 4 par un ressort 42. Par conséquent, au repos, c'est à dire en l'absence d'alimentation de l' électroaimant 5, la bille 43 assure l'étanchéité au niveau du siège 44 et isole par conséquent la membrane vibrante 3 du réservoir 2. En revanche, dès que l'électroaimant 5 est alimenté, le noyau ferromagnétique 41 devient aimanté et attire la bille 43 qui se déplace alors contre l'effet du ressort 42 pour se décoller de son siège 44 et établir une communication entre la seconde section de passage 272 et une section de passage ultérieure 273 qui est en communication directe avec un espace 274 situé en contact des trous de passage 30 de la membrane perforée 3.On the other hand, the button 9 which can be an electrical contactor is connected by a supply line 8 in the form of a flat track, to the electronic control system 7. The supply line 8 can for example run the along the dome 20 and enter the base 1 at the retaining edge 15. Thus, by pressing the button 9 the electrical circuit is closed and the electronic control system is supplied. The bottom 22 of the tank 2 defines an outlet opening 23 which is extended by a fluid product supply passage 27 which defines just downstream of the opening 23 a first passage section 271 which is directed downwards. This first passage section 271 is defined by a tube 230 formed by the bottom 22 of the tank. This tubing 230 also serves as a connection to a valve body 40 which defines a connection sleeve 46 on the tubing 230. Beyond the first passage section 271, the valve body 40 defines a second passage section 272 at the level from which an inlet valve 4 is formed. This inlet valve 4 is an electromagnetic valve comprising a ferromagnetic core 41 located in the second passage section 272 which is closed at one end by a plug 45. The electromagnet 5 is located just behind the plug 45 so it can induce an electromagnetic field up to the level of the ferromagnetic core 41. On the other hand, a valve ball 43, made of steel for example, is pressed against a seat 44 formed by the body 4 by a spring 42. Consequently, at rest , that is to say in the absence of supply of the electromagnet 5, the ball 43 seals at the level of the seat 44 and consequently isolates the vibrating membrane 3 from the reservoir 2. On the other hand, as soon as the electromagnet 5 is energized, the ferromagnetic core 41 becomes magnetized and attracts the ball 43 which then moves against the effect of the spring 42 to detach from its seat 44 and establish communication between the second passage section 272 and a passage section 273 which is in direct communication with a space 274 situated in contact with the passage holes 30 of the perforated membrane 3.
Selon l'invention, la membrane perforée 3 est directement alimentée en produit fluide depuis le réservoir 2 du seul fait de la gravité lorsque le clapet d'admission 4 est ouvert. On peut dire que la membrane est alors en contact direct du produit fluide du réservoir, car le passage 27 peut être considéré comme une partie ou une extension du réservoir. En effet, on peut tout à fait bien imaginer des formes de réalisation dans lesquelles la membrane est située directement au niveau du réservoir pour en constituer une partie de paroi. En d'autres termes, la membrane est reliée directement en continu et en permanence au réservoir, lorsque le clapet est ouvert. Ceci est possible du fait que le réservoir 2 est situé au-dessus de la membrane perforée 3 lorsque le distributeur est maintenu dans la position représentée sur la figure unique, c'est à dire avec le fond dirigé vers le bas et le bouton d'actionnement dirigé vers le haut. Cette alimentation par gravité est possible du fait de l'orientation du passage d'alimentation 27 qui s'étend d'abord vers le bas avec sa première section 271 puis horizontalement vers la membrane 3 avec ses sections 272 et 273. Pour assurer un bon fonctionnement, c'est à dire une bonne qualité de pulvérisation au niveau de la membrane perforée 3, il suffit que le clapet d'admission 4 soit ouvert pendant les périodes d'actionnement du distributeur. En revanche, il est avantageux que la membrane 3 soit isolée du réservoir 2 lorsque le distributeur est au repos de sorte que toute fuite ou suintement à travers les trous 30 de la membrane perforée 3 est évité(e). Selon une forme de réalisation pratique, le bouton 9 peut à la fois commander la mise sous tension du système électronique de commande de l'élément piezo-électrique 34 et de l' électro-aimant 5, et ceci de manière simultanée de sorte que l'ouverture du clapet coïncide avec la pulvérisation du produit à travers la membrane. Lorsque le clapet est ouvert, le passage établit une communication directe continue depuis le réservoir jusqu'à la membrane perforée qui forme ainsi un élément de paroi du réservoir avec sa paroi interne.According to the invention, the perforated membrane 3 is directly supplied with fluid from the reservoir 2 by the mere fact of gravity when the intake valve 4 is open. We can say that the membrane is then in direct contact with the fluid in the reservoir, since the passage 27 can be considered as a part or an extension of the reservoir. Indeed, one can quite well imagine embodiments in which the membrane is located directly at the level of the reservoir to form part of the wall. In other words, the membrane is directly and continuously connected directly to the reservoir, when the valve is open. This is possible because the reservoir 2 is located above the perforated membrane 3 when the dispenser is held in the position shown in the single figure, that is to say with the bottom facing down and the button. actuation directed upwards. This gravity feed is possible due to the orientation of the feed passage 27 which first extends downward with its first section 271 and then horizontally towards the membrane 3 with its sections 272 and 273. To ensure good operation, that is to say a good quality of spraying at the level of the perforated membrane 3, it suffices that the inlet valve 4 is open during the actuation periods of the dispenser. On the other hand, it is advantageous for the membrane 3 to be isolated from the reservoir 2 when the dispenser is at rest so that any leak or seepage through the holes 30 in the perforated membrane 3 is avoided. According to a practical embodiment, the button 9 can both control the powering up of the electronic control system of the piezoelectric element 34 and the electromagnet 5, and this simultaneously so that the The opening of the valve coincides with the spraying of the product through the membrane. When the valve is open, the passage establishes continuous direct communication from the tank to the perforated membrane which thus forms a wall element of the tank with its internal wall.
Grâce à l'invention, une membrane perforée vibrante peut être alimentée en produit fluide à partir d'un réservoir à une pression sensiblement égale à la pression atmosphérique et sans risque de fuite au niveau de la membrane lorsque le distributeur est au repos. Thanks to the invention, a vibrating perforated membrane can be supplied with fluid from a reservoir at a pressure substantially equal to atmospheric pressure and without risk of leakage at the membrane when the dispenser is at rest.
