Dispositif d'obturation de l'orifice de distribution d'un distributeur de produit fluide.Device for closing the dispensing orifice of a fluid dispenser.

La présente invention concerne un dispositif d'obturation de l'orifice de distribution d'un distributeur de produit fluide ainsi qu'une tête de distribution et un distributeur de produit fluide comportant un tel dispositif d'obturation.The present invention relates to a device for closing the dispensing orifice of a fluid dispenser as well as a dispensing head and a fluid dispenser comprising such a shutter device.

Il est connu dans l'état de la technique d'utiliser un capot amovible pour obturer l'orifice de distribution d'un tel distributeur.It is known in the prior art to use a removable cover to close the dispensing orifice of such a dispenser.

Le document WO 98/00354 divulgue un capot amovible qui, lorsqu'il est mis en place, obture de manière étanche l'orifice de distribution à l'aide d'un élément d'obturation, en particulier un tampon déformable, disposé sur la paroi de fond du capot. Ce dispositif assure une bonne étanchéité, mais n'empêche pas la contamination, notamment bactérienne, de la petite quantité de produit restant à proximité de l'orifice du distributeur après un actionnement du distributeur. Par conséquent, au prochain actionnement, une petite quantité de produit contaminé risque d'être distribuée.Document WO 98/00354 discloses a removable cover which, when put in place, seals the dispensing orifice with a sealing element, in particular a deformable pad, placed on the hood bottom wall. This device ensures a good seal, but does not prevent contamination, in particular bacterial, of the small amount of product remaining near the orifice of the dispenser after actuation of the dispenser. Therefore, the next time it is operated, a small amount of contaminated product may be dispensed.

Le document WO 93/24164 divulgue un capot fendu adapté à permettre le séchage rapide de la partie de distribution. Ce capot peut comporter dans son fond un tampon absorbant pouvant être imprégné d'un conservateur approprié. Ce tampon doit permettre le séchage rapide et n'agit pas en tant qu'obturateur.Document WO 93/24164 discloses a split cover adapted to allow rapid drying of the dispensing part. This cover may include at its bottom an absorbent pad which can be impregnated with an appropriate preservative. This pad must allow rapid drying and does not act as a shutter.

La présente invention a pour but de fournir un dispositif d'obturation qui ne présente pas les inconvénients précités.The present invention aims to provide a closure device which does not have the aforementioned drawbacks.

En particulier, la présente invention a pour but de fournir un dispositif d'obturation qui empêche toute contamination bactérienne au niveau de l'orifice de distribution entre deux actionnements.In particular, the object of the present invention is to provide a closure device which prevents any bacterial contamination at the level of the dispensing orifice between two actuations.

La présente invention a aussi pour but de fournir un dispositif d'obturation qui soit simple et peu coûteux à fabriquer et à assembler.The present invention also aims to provide a closure device which is simple and inexpensive to manufacture and assemble.

La présente invention a également pour but de fournir un tel dispositif d'obturation qui soit facile à utiliser pour l'utilisateur du distributeur.The present invention also aims to provide such a closure device which is easy to use for the user of the dispenser.

La présente invention a donc pour objet un dispositif d'obturation de l'orifice de distribution d'un distributeur de produit fluide, comportant un capot amovible pourvu d'un élément d'obturation qui, en position fermée, obture ledit orifice, ledit élément d'obturation comportant une substance bactéricide et/ou bactériostatique agissant sur le faible quantité de produit restant au niveau dudit orifice après l' actionnement du distributeur. Avantageusement, l'élément d'obturation a une forme extérieure qui correspond au profil externe de l'orifice d'obturation.The present invention therefore relates to a device for closing the dispensing orifice of a fluid dispenser, comprising a removable cover provided with a closing element which, in the closed position, closes said orifice, said element obturation comprising a bactericidal and / or bacteriostatic substance acting on the small amount of product remaining at said orifice after actuation of the dispenser. Advantageously, the closure element has an external shape which corresponds to the external profile of the closure orifice.

De préférence, ledit élément d'obturation est réalisé sous la forme d'une bille. Avantageusement, l'élément d'obturation est disposé sur une paroi de fond du capot, en saillie de celle-ci.Preferably, said closure element is produced in the form of a ball. Advantageously, the closure element is arranged on a bottom wall of the cover, projecting from the latter.

Selon une première variante, l'élément d'obturation est réalisé en un matériau incorporant la substance bactéricide et/ou bactériostatique.According to a first variant, the closure element is made of a material incorporating the bactericidal and / or bacteriostatic substance.

Selon une seconde variante, l'élément d'obturation est enduit avec la substance bactéricide et/ ou bactériostatique. Avantageusement, ladite substance bactéricide et/ou bactériostatique n'agit que pas contact, sans relarguage d'ions dans le produit.According to a second variant, the sealing element is coated with the bactericidal and / or bacteriostatic substance. Advantageously, said bactericidal and / or bacteriostatic substance acts only on contact, without releasing ions into the product.

La présente invention a aussi pour objet une tête de distribution d'un distributeur de produit fluide, ladite tête de distribution comportant un orifice de distribution et un dispositif d'obturation dudit orifice, tel que défini ci-dessus. Avantageusement, la tête de distribution est un poussoir nasal comportant un orifice de distribution central axial disposé au fond d'une cuvette réalisé dans extrémité de ladite tête de distribution, ledit capot étant réalisé sous la forme d'un manchon creux se fixant autour dudit poussoir nasal, ledit capot comportant une bille fixée sur la paroi de fond dudit capot, ledit diamètre de la bille correspondant sensiblement au diamètre de la cuvette pour éliminer en position fermée du capot toute présence de produit dans ladite cuvette.The present invention also relates to a dispensing head of a fluid dispenser, said dispensing head comprising a dispensing orifice and a device for closing said orifice, as defined above. Advantageously, the dispensing head is a nasal pusher comprising an axial central dispensing orifice disposed at the bottom of a bowl produced in the end of said dispensing head, said cover being produced in the form of a hollow sleeve fixing around said pusher nasal, said cover comprising a ball fixed to the bottom wall of said cover, said diameter of the ball substantially corresponding to the diameter of the bowl to eliminate in the closed position of the cover any presence of product in said bowl.

La présente invention a encore pour objet un distributeur de produit fluide, comportant un réservoir de produit et une tête de distribution, tel qu'un poussoir, pourvue d'un orifice de distribution, comportant un dispositif d'obturation dudit orifice, tel que définit ci-dessus.The present invention also relates to a fluid dispenser, comprising a product reservoir and a dispensing head, such as a pusher, provided with a dispensing orifice, comprising a device for closing said orifice, as defined above.

D'autres caractéristiques et avantages de la présente invention apparaîtront au cours de la description détaillée suivante d'un mode de réalisation avantageux de l'invention, donné à titre d'exemple non limitatif, en référence aux dessins joints, sur lesquels : - la figure 1 est une vue schématique en coupe longitudinale d'un dispositif d'obturation selon un mode de réalisation préféré de l'invention, en position fermée, et la figure 2 est une vue partielle agrandie du dispositif de la figure 1, en position ouverte. La présente invention couvre un dispositif d'obturation ainsi qu'une tête de distribution et un distributeur de produit fluide comportant un tel dispositif d'obturation,. Le dispositif d'obturation de l'invention s'appliquant à tous les types de distributeur, celui-ci ne sera pas décrit en détail ci-après. De même, la tête de distribution 4 représentée sur les dessins est un poussoir nasal, mais le dispositif d'obturation de l'invention ne se limite pas à ce type de poussoir. L'invention s'applique en fait sur tout orifice d'un distributeur de produit susceptible d'être contaminé.Other characteristics and advantages of the present invention will appear during the following detailed description of an advantageous embodiment of the invention, given by way of nonlimiting example, with reference to the accompanying drawings, in which: Figure 1 is a schematic longitudinal sectional view of a closure device according to a preferred embodiment of the invention, in the closed position, and Figure 2 is an enlarged partial view of the device of Figure 1, in the open position . The present invention covers a closure device as well as a dispensing head and a fluid dispenser comprising such a closure device. Since the closure device of the invention applies to all types of dispenser, it will not be described in detail below. Similarly, the dispensing head 4 shown in the drawings is a nasal plunger, but the closure device of the invention is not limited to this type of plunger. The invention is in fact applicable to any orifice of a product dispenser liable to be contaminated.

En référence à la figure 1, le poussoir nasal 4 comprend à son extrémité un orifice de distribution axial 5, et du côté opposé une surface d'appui 6 pour actionner le distributeur, ainsi que des moyens de connexion 7 de la tête 4 sur un organe de distribution, telle qu'une pompe (non représentée). Avantageusement, la tête comporte dans le canal d'expulsion menant à l'orifice 5 un gicleur interne ou insert 19 pour limiter le volume mort. La tête peut également comporter un obturateur disposé en amont de l'orifice.With reference to FIG. 1, the nasal plunger 4 comprises at its end an axial dispensing orifice 5, and on the opposite side a bearing surface 6 for actuating the dispenser, as well as connection means 7 for the head 4 on a dispensing member, such as a pump (not shown). Advantageously, the head comprises in the expulsion channel leading to the orifice 5 an internal nozzle or insert 19 to limit the dead volume. The head may also include a shutter disposed upstream of the orifice.

Le dispositif d'obturation comporte un capot amovible 10, qui, dans sa position fermée représentée sur la figure 1, obture l'orifice de distribution 5. Pour ce faire, ledit capot comprend un élément d'obturation 20. Cet élément d'obturation peut avantageusement être disposé sur une paroi de fond 18 du capot 10, et est de préférence réalisé sous la forme d'une bille.The closure device comprises a removable cover 10, which, in its closed position shown in FIG. 1, closes the dispensing orifice 5. To do this, said cover comprises a closure element 20. This closure element can advantageously be arranged on a bottom wall 18 of the cover 10, and is preferably produced in the form of a ball.

Selon l'invention, ledit élément d'obturation 20 comporte une substance bactéricide et/ou bactériostatique agissant sur le produit restant au niveau dudit orifice 5 après l'actionnement du distributeur. La substance bactéricide et/ ou bactériostatique peut être incorporé dans le matériau constituant l'élément d'obturation 20, où elle peut être enduite sur ledit élément d'obturation 20. De préférence, ladite substance bactéricide et/ ou bactériostatique n'agit que par contact sans relarguage d'ions dans le produit.According to the invention, said closure element 20 comprises a bactericidal and / or bacteriostatic substance acting on the product remaining at said orifice 5 after actuation of the dispenser. The bactericidal and / or bacteriostatic substance can be incorporated into the material constituting the obturating element 20, where it can be coated on said obturating element 20. Preferably, said bactericidal and / or bacteriostatic substance acts only by contact without releasing ions into the product.

En référence à la figure 2, qui est une vue schématique agrandie du dispositif d'obturation de la figure 1 en position ouverte, il est visible que l'orifice de distribution 5 du poussoir nasal 4 est ménagé au fond d'une sorte de cuvette 50 prévue dans la paroi d'extrémité extérieure de ladite tête 4. Cette réalisation correspond à une tête de distribution nasale typique. Il est dans ce cas préféré que l'élément d'obturation 20 du dispositif d'obturation soit réalisé avec une forme extérieure qui corresponde sensiblement à la forme de ladite cuvette 50. De cette manière, lorsque le capot 10 est en position fermée, tout produit restant dans ladite cuvette 50 après l'actionnement du distributeur est enlevé par l'élément d'obturation qui vient occuper le volume correspondant. Ainsi, l'élément d'obturation 20 est avantageusement réalisé sous la forme d'une bille dont le diamètre correspond sensiblement au diamètre de ladite cuvette 50. Lorsque le capot 10 est en position fermée, comme représenté sur la figure 1, la substance bactéricide et/ou bactériostatique dudit élément d'obturation 20 agit avantageusement sur la faible quantité de produit contenu dans le petit canal 51, visible sur la figure 2, qui forme l'orifice de distribution 5 et relie le canal d'expulsion de la tête 4 avec le fond de ladite cuvette 50. Ainsi, toute quantité de produit restant à proximité dudit orifice 5, après l'actionnement du distributeur, est empêché d'être contaminé par la mise en place du capot 10, par l'intermédiaire de l'élément d'obturation 20 comportant une substance bactéricide et/ ou bactériostatique.Referring to Figure 2, which is an enlarged schematic view of the closure device of Figure 1 in the open position, it is visible that the dispensing orifice 5 of the nasal plunger 4 is formed at the bottom of a sort of bowl 50 provided in the outer end wall of said head 4. This embodiment corresponds to a typical nasal delivery head. In this case, it is preferred that the shutter element 20 of the shutter device is made with an external shape which corresponds substantially to the shape of said bowl 50. In this way, when the cover 10 is in closed position, any product remaining in said bowl 50 after actuation of the dispenser is removed by the closure element which comes to occupy the corresponding volume. Thus, the closure element 20 is advantageously produced in the form of a ball whose diameter corresponds substantially to the diameter of said bowl 50. When the cover 10 is in the closed position, as shown in FIG. 1, the bactericidal substance and / or bacteriostatic of said obturation element 20 advantageously acts on the small quantity of product contained in the small channel 51, visible in FIG. 2, which forms the dispensing orifice 5 and connects the expulsion channel of the head 4 with the bottom of said bowl 50. Thus, any quantity of product remaining near said orifice 5, after actuation of the dispenser, is prevented from being contaminated by the installation of the cover 10, by means of the obturation element 20 comprising a bactericidal and / or bacteriostatic substance.

Bien entendu, la présente invention ne se limite pas à l'exemple de réalisation particulier représenté sur les figures et, en particulier, l'élément d'obturation 20 n'est pas nécessairement réalisé sous la forme d'une bille s'adaptant dans une cuvette prévue dans extrémité de la tête de distribution. Au contraire, la présente invention fournit un élément d'obturation 20, incorporant une substance bactéricide et/ ou bactériostatique, et qui en position fermée du capot 10 empêche toute contamination du produit restant dans ou à proximité de l'orifice de distribution 5. Il est même envisageable que l'élément d'obturation 20 pénètre à l'intérieur de l'orifice de distribution 5, si cela est souhaité. De même, le capot 10 n'est pas nécessairement réalisé sous la forme d'un manchon creux tel que représenté sur les dessins, mais au contraire peut avoir toute forme appropriée.Of course, the present invention is not limited to the particular embodiment shown in the figures and, in particular, the closure element 20 is not necessarily produced in the form of a ball fitting in a bowl provided in the end of the dispensing head. On the contrary, the present invention provides a sealing element 20, incorporating a bactericidal and / or bacteriostatic substance, and which in the closed position of the cover 10 prevents any contamination of the product remaining in or near the dispensing orifice 5. It it is even conceivable that the closure element 20 penetrates inside the dispensing orifice 5, if desired. Likewise, the cover 10 is not necessarily produced in the form of a hollow sleeve as shown in the drawings, but on the contrary may have any suitable shape.

Le capot 10 peut être fixé dans sa position fermée sur la tête de distribution 4, avantageusement par encliquetage. Pour ce faire, il peut comporter des moyens de fixation 15 tel qu'une ou plusieurs nervures d'encliquetage qui s'enchquètent sur une partie de ladite tête 4. Bien entendu, les moyens de fixation 15 du capot 10 sur la tête 4 peuvent avoir une forme quelconque appropriée. Ainsi, le capot 10 pourrait être vissé sur la tête 4, ou encore être fixé à un autre élément du distributeur, tel que par exemple le récipient de produit (non représenté). La présente invention fournit donc un dispositif d'obturation de l'orifice de distribution 5 d'un distributeur de produit fluide qui est facile à mettre en place et à retirer, qui garantie une obturation de l'orifice 5 en position fermée, et simultanément empêche toute contamination du produit au niveau dudit orifice de distribution 5 dans cette position fermée. The cover 10 can be fixed in its closed position on the dispensing head 4, advantageously by snap-fastening. To do this, it may include fixing means 15 such as one or more snap-fitting ribs which engage on a part of said head 4. Of course, the fixing means 15 of the cover 10 on the head 4 can have any suitable form. Thus, the cover 10 could be screwed onto the head 4, or even be fixed to another element of the dispenser, such as for example the product container (not shown). The present invention therefore provides a device for closing the dispensing orifice 5 of a fluid dispenser which is easy to set up and remove, which guarantees that the orifice 5 is closed in the closed position, and simultaneously prevents any contamination of the product at the level of said dispensing orifice 5 in this closed position.
