Description

La présente invention a trait à une tête pour la distribution d'un produit de consistance visqueuse selon le préambule de la revendication 1, notamment sous forme d'une pâte, d'un gel, d'une crème, d'un lait, tels que pouvant être utilisés notamment dans le domaine de la cosmétique ou de la pharmacie. L'invention concerne également un ensemble de conditionnement et de distribution équipé d'une telle tête. L'invention est tout particulièrement adaptée aux dispositifs nécessitant une reprise d'air, et dont le contenu doit être protégé des microbes ou bactéries contenus dans l'air ambiant.The present invention relates to a head for dispensing a product of viscous consistency according to the preamble of claim 1, in particular in the form of a paste, a gel, a cream, a milk, such as can be used in particular in the field of cosmetic or pharmacy. The invention also relates to a set of packaging and distribution equipped with such a head. The invention is everything particularly suitable for devices requiring air intake, and whose contents must be protected from microbes or bacteria contained in the ambient air.

On connaít un certain nombre de dispositifs dans lesquels l'orifice de reprise d'air nécessaire à son fonctionnement est isolé du contenu du récipient par un filtre pouvant être imbibé d'une composition anti microbienne. De tels dispositifs sont décrits notamment dans la demande de brevet EP-A-0 500 249. Dans ce dispositif, destiné au conditionnement et à la distribution de compositions stériles, la reprise d'air est effectuée via un circuit distinct du circuit de distribution du produit. Bien que satisfaisant du point de vue de la protection de la composition stérile, ce dispositif, en raison de la présence de deux circuits différents, présente l'inconvénient d'être relativement complexe, et, de ce fait coûteux à réaliser. En outre, le produit résiduel situé entre le filtre et l'orifice de sortie du produit peut être au contact d'air non filtré. Enfin, le filtre est placé derrière un ou plusieurs orifices de reprise d'air, lesquels sont sujets à encrassement.We know a number of devices in which the air intake orifice necessary for its operation is isolated from the contents of the container by a filter can be soaked with an anti microbial composition. Such devices are described in particular in patent application EP-A-0 500 249. In this device, intended for the packaging and distribution of sterile compositions, the air intake is carried out via a circuit separate from the distribution circuit of the product. Although satisfactory from the point of view of the protection of the composition sterile, this device, due to the presence of two different circuits, presents the disadvantage of being relatively complex, and therefore costly to carry out. In in addition, the residual product located between the filter and the product outlet may be in contact with unfiltered air. Finally, the filter is placed behind one or more orifices return air, which are subject to contamination.

Des dispositifs similaires sont décrits dans la demande de brevet EP-A-0 485 342 et dans la demande PCT 93/10015. Les inconvénients sont les mêmes que ceux discutés en référence à la demande EP-A-0 500 249.Similar devices are described in patent application EP-A-0 485 342 and in PCT application 93/10015. The disadvantages are the same as those discussed with reference to application EP-A-0 500,249.

Du document FR-A-2 588 835 il est connu de distribuer du produit au travers des pores ou orifices d'une membrane fixée sur le goulot d'un flacon. Un des inconvénients d'une telle structure tient principalement au fait que, le produit s'écoulant au travers des pores, il empêche toute reprise d'air au travers des pores dans la mesure ou ceux-ci, lorsque cesse la pression apte à provoquer la distribution, sont remplis de produit. En outre, un tel dispositif permet difficilement la distribution de compositions très visqueuses. En outre les pores, en subissant au fil des utilisations, une succession de dilatations/repos, ont leur section au repos pouvant se modifier de manière substantielle entre la première utilisation du récipient et la dernière.From document FR-A-2 588 835, it is known to distribute product through pores or orifices of a membrane fixed on the neck of a bottle. One of disadvantages of such a structure is mainly due to the fact that, the product flowing through the pores, it prevents any return of air through the pores as far as these, when the pressure stops capable of causing the distribution, are filled with product. In addition, such a device hardly allows the distribution of very viscous compositions. Additionally pores, undergoing over the uses, a succession of dilations / rest, have their section at rest that can change substantially between the first use of the container and the last.

Une tête selon le préambule de la revendication 1 est connue du WO-A-92 12065. Aussi, est-ce un des objets de l'invention que de réaliser une tête de distribution d'un produit devant être conservé dans des conditions relativement stériles, et résolvant en tout ou partie, les problèmes discutés en référence aux dispositifs conventionnels.A head according to the preamble of claim 1 is known from WO-A-92 12065. Also, is it one of the objects of the invention to produce a dispensing head a product to be stored under relatively sterile conditions, and solving all or part of the problems discussed with reference to the devices conventional.

C'est en particulier un objet de l'invention que de fournir un dispositif dans lequel la distribution du produit et la reprise d'air sont réalisées au travers du même circuit, tout en permettant une protection satisfaisante du produit au regard des microbes ou bactéries de l'air ambiant.It is in particular an object of the invention to provide a device in which product distribution and air intake are carried out through the same circuit, while allowing satisfactory protection of the product with regard to ambient air microbes or bacteria.

D'autres objets de l'invention apparaítront de manière détaillée dans la description qui suit.Other objects of the invention will appear in detail in the description following.

Selon l'invention, ces objets sont atteints en réalisant une tête pour la distribution d'un produit visqueux contenu à l'intérieur d'un récipient, ladite tête étant du type à au moins un orifice de sortie obturé sélectivement par un organe d'obturation sous forme d'un élément élastiquement déformable apte à s'écarter sous la pression du produit pour dégager ledit ou lesdits orifice(s) et laisser passer le produit en vue de sa distribution, et à revenir par rappel élastique, en contact de fermeture avec un siège formé par ladite tête de distribution, lorsque cesse la pression, une portion constituée d'un matériau poreux, étanche au produit, étant prévue de manière à permettre, une reprise d'air filtré à l'intérieur dudit récipient, au travers dudit matériau poreux, ladite portion étant au moins en partie, accessible directement depuis l'extérieur de la tête de distribution, ledit (ou lesdits) orifice(s) de sortie étant distinct(s) des pores ou cellules formant la portion poreuse. En d'autres termes, une partie au moins de ladite portion est en communication directe avec l'extérieur. Une telle structure se distingue des dispositifs conventionnels dans lesquels, notamment, l'élément de filtration est disposé à l'intérieur de la tête de distribution, et est en communication avec l'extérieur via un ou plusieurs orifices, généralement de petite taille.According to the invention, these objects are achieved by making a head for the distribution of a viscous product contained inside a container, said head being of the at least one outlet orifice selectively closed by a shutter member under form of an elastically deformable element capable of spreading under the pressure of the product to clear said orifice (s) and allow the product to pass through of its distribution, and to return by elastic return, in closing contact with a seat formed by said dispensing head, when the pressure ceases, a portion made of a porous material, impermeable to the product, being provided with so as to allow a return of filtered air inside said container, through of said porous material, said portion being at least partially accessible directly from the outside of the dispensing head, said orifice (s) outlet being distinct from the pores or cells forming the porous portion. In in other words, at least part of said portion is in communication direct to the outside. Such a structure is distinguished from the devices in which, in particular, the filter element is arranged at inside the distribution head, and is in communication with the outside via a or several orifices, generally small.

Le produit s'écoule au travers du ou des orifices de sortie, réalisés entre le siège et une extrémité libre ou un bord libre de la membrane. Le produit ne s'écoule donc pas au travers des pores de la portion poreuse, lesquels peuvent jouer pleinement leur fonction de reprise d'air lorsque la membrane élastiquement déformable revient en position de fermeture. En d'autres termes, le produit sort par un ou plusieurs orifices formés entre le siège et la membrane lorsque celle-ci est écartée, tandis que la reprise d'air est assurée au moyens d'orifices distincts de l'orifice de sortie, en l'occurrence par les pores ou cellules de ladite portion poreuse. Les deux fonctions peuvent être assurées de manière pleinement efficace. A la différence du document FR-2 588 835, dans lequel la taille des pores augmente sous la pression du produit pour laisser passer ce dernier, selon l'invention, la taille des pores n'augmente pas lors de la distribution. Au contraire, lorsque le matériau est constitué d'un bloc de mousse à cellules ouvertes, les cellules ouvertes peuvent même se comprimer sous la pression du produit, en fonction de la position du bloc de mousse par rapport au flux de produit.The product flows through the outlet orifices, made between the seat and a free end or a free edge of the membrane. The product does not flow therefore not through the pores of the porous portion, which can act fully their return air function when the membrane resiliently deformable returns to the closed position. In other words, the product comes out by one or more orifices formed between the seat and the membrane when the latter is discarded, while the air intake is ensured by means of separate orifices of the outlet, in this case by the pores or cells of said portion porous. Both functions can be fully performed effective. Unlike document FR-2 588 835, in which the size of the pores increases under the pressure of the product to let it pass, according to the invention, the pore size does not increase during distribution. On the contrary, when the material consists of a block of open cell foam, the open cells can even compress under product pressure, depending on the position of the foam block in relation to the product flow.

La réalisation de la tête de distribution se trouve ainsi simplifiée en permettant de se dispenser d'orifices ou passages auxiliaires propres à définir un circuit de reprise d'air distinct du circuit de distribution du produit, lesquels orifices ou passages sont souvent sujets à encrassement. En outre, le produit est parfaitement isolé de l'air ambiant, et des microbes ou bactéries de l'air ambiant. Par ailleurs, la conception de la tête de distribution à reprise d'air peut être identique dans sa forme à celle d'une tête de distribution sans reprise d'air. Elle nécessite seulement pour ladite portion, un matériau différent de ceux utilisés traditionnellement pour des systèmes sans reprise d'air. Le surcoût est négligeable.The realization of the dispensing head is thus simplified by allowing dispense with orifices or auxiliary passages suitable for defining a circuit of air intake separate from the product distribution circuit, which orifices or passages are often subject to contamination. In addition, the product is perfectly isolated from ambient air, and microbes or bacteria from ambient air. Furthermore, the design of the return air distribution head can be identical in shape to that of a distribution head without air intake. She requires only for said portion, a material different from those used traditionally for systems without return air. The additional cost is negligible.

De plus, un tel élément poreux dont une partie au moins est directement accessible depuis l'extérieur du récipient peut être nettoyé facilement, simplement en le passant sous l'eau chaude, ce qui était plus difficile à réaliser pour les dispositifs conventionnels où la partie filtrante était située derrière un orifice formé dans une paroi de la tête de distribution. En outre, la surface réalisant la filtration d'air et la reprise d'air est beaucoup plus grande que lorsque la reprise d'air est effectuée via un ou plusieurs orifices. A titre d'exemple, la surface d'échange avec l'extérieur peut aller de quelques mm2 à quelques cm2.In addition, such a porous element at least part of which is directly accessible from the outside of the container can be easily cleaned, simply by passing it under hot water, which was more difficult to achieve for conventional devices where the part filter was located behind an orifice formed in a wall of the dispensing head. In addition, the area carrying out the air filtration and the air intake is much larger than when the air intake is carried out via one or more orifices. For example, the exchange surface with the outside can range from a few mm 2 to a few cm 2 .

Avantageusement, le matériau poreux peut être imbibé d'un produit antimicrobien, de manière à améliorer encore la protection du produit contenu dans le récipient. A titre d'indication, le matériau poreux à une porosité comprise entre 1 µm et 500 µm, et de préférence, comprise entre 10 µm et 200 µm. La porosité du matériau est choisie, en fonction notamment de la viscosité et de la nature du produit conditionné.Advantageously, the porous material can be soaked with an antimicrobial product, so as to further improve the protection of the product contained in the container. As an indication, the porous material has a porosity between 1 µm and 500 µm, and preferably between 10 µm and 200 µm. The porosity of the material is chosen, depending in particular on the viscosity and the nature of the product conditioning.

Avantageusement, ladite portion est constituée de tout ou partie de l'organe d'obturation ou du siège, de manière à permettre une reprise d'air sensiblement au voisinage du ou des orifices de sortie du produit. Ainsi, l'acheminement du produit depuis le récipient vers l'orifice de sortie se fait par le même circuit que celui de l'air vers le récipient, les orifices d'entrée d'air étant toutefois différents du ou des orifices de sortie du produit. Les orifices d'entrée d'air étant situés à proximité du ou des orifices de sortie du produit, tout le produit contenu dans le récipient, y compris le produit résiduel dans le circuit de sortie du produit, en amont de l'organe d'obturation est conservé dans des conditions relativement stériles. Par ailleurs, la reprise d'air localisée de manière adjacente à l'orifice de sortie permet une meilleure fermeture, notamment plus rapide, de l'organe d'obturation. En outre, dans le cas où l'ensemble est recouvert, notamment en position de stockage, d'un capot ou d'un capuchon, celui-ci peut être de taille réduite par rapport à ceux utilisés dans les dispositifs conventionnels, dans la mesure, où seule la zone entourant l'orifice de sortie à besoin d'être recouverte.Advantageously, said portion consists of all or part of the organ shutter or seat, so as to allow an air intake substantially in the vicinity of the product outlet orifices. Thus, the routing of the product from the container to the outlet is done by the same circuit as that of the air towards the container, the air inlet orifices being different from the or product outlet ports. The air inlet ports being located at near the product outlet port (s), all the product contained in the container, including the residual product in the product outlet circuit, in upstream of the obturation member is kept under relatively conditions sterile. In addition, the air intake located adjacent to the orifice of outlet allows better, especially faster, closure of the organ shutter. In addition, in the case where the assembly is covered, in particular in storage position, hood or cap, this can be of size reduced compared to those used in conventional devices, in the measure, where only the area surrounding the outlet needs to be covered.

Avantageusement en effet, la tête de distribution est surmontée d'un capot amovible, pour améliorer la protection du produit en position de stockage.Advantageously, in fact, the dispensing head is surmounted by a cover removable, to improve product protection in the storage position.

Selon un premier mode de réalisation, le siège est situé au centre d'une ouverture formée par ladite tête de distribution, l'organe d'obturation étant constitué d'un organe annulaire dont un bord intérieur libre, délimite avec le siège, l'orifice de sortie du produit, ledit bord intérieur étant, en position de fermeture en appui sur ledit siège. Le siège peut être maintenu en position dans l'ouverture au moyen de pattes disposées radialement tout autour du siège central, et reliées d'une part au siège, et d'autre part à un élément de montage disposé dans ladite ouverture.According to a first embodiment, the seat is located in the center of an opening formed by said dispensing head, the shutter member consisting of a annular member including a free inner edge, defining with the seat, the orifice outlet of the product, said inner edge being, in the closed position pressing on said seat. The seat can be held in position in the opening by means of legs arranged radially all around the central seat, and connected on the one hand to the seat, and secondly to a mounting element disposed in said opening.

Selon un second mode de réalisation, le siège est constitué d'un organe annulaire monté dans une ouverture formée par ladite tête de distribution, l'organe d'obturation étant monté de manière à, sous la pression du produit, dégager au moins un orifice de sortie situé sur une portion périphérique de ladite ouverture.According to a second embodiment, the seat consists of an annular member mounted in an opening formed by said dispensing head, the member shutter being mounted so as to, under the pressure of the product, release at at least one outlet orifice situated on a peripheral portion of said opening.

Le récipient peut être à parois déformables, le produit étant mis sous pression par appui exercé sur lesdites parois déformables. A titre d'exemple, il s'agit d'un tube ou d'un flacon souple.The container may have deformable walls, the product being pressurized by support exerted on said deformable walls. For example, it is a tube or a flexible bottle.

Selon un mode de réalisation, la tête de distribution forme un bouton poussoir apte à être monté sur une tige creuse surmontant une pompe à actionnement manuel, ledit bouton poussoir permettant l'actionnement de ladite pompe. Cela rend possible l'utilisation d'une pompe ne comportant pas de reprise d'air propre à la pompe, permettant ainsi de réaliser une pompe avec un coût de revient réduit de manière substantielle par rapport aux pompes conventionnelles.According to one embodiment, the dispensing head forms a push button suitable for mounting on a hollow rod surmounting an actuating pump manual, said push button allowing actuation of said pump. it makes it possible to use a pump that does not have an air return specific to the pump, thus making it possible to produce a pump with a reduced cost price substantially compared to conventional pumps.

Selon un autre mode de réalisation, la tête de distribution forme un embout de distribution apte à permettre une application localisée du produit, ledit embout comportant une première partie en un matériau poreux formant le siège (ou l'organe d'obturation), et une seconde partie en un matériau non poreux, et formant ledit organe d'obturation (ou le siège). Un tel embout est particulièrement adapté à la distribution d'un produit capillaire, lorsque celle-ci doit être localisée, notamment à la base des cheveux.According to another embodiment, the dispensing head forms a nozzle distribution capable of allowing localized application of the product, said nozzle comprising a first part made of a porous material forming the seat (or the shutter member), and a second part made of a non-porous material, and forming said shutter member (or seat). Such a tip is particularly suitable for dispensing a hair product, when it must be located, especially at the base of the hair.

Avantageusement, ledit embout de distribution présente un corps monté sur le récipient, ladite seconde partie étant obtenue de moulage avec le corps. Un tel embout peut être réalisé en polyéthylène basse densité.Advantageously, said dispensing nozzle has a body mounted on the container, said second part being obtained by molding with the body. Such tip can be made of low density polyethylene.

Selon un autre mode de réalisation avantageux, l'organe d'obturation est formé d'un matériau poreux, élastiquement déformable. On réalise ainsi d'une seule pièce, un élément formant à la fois un organe d'obturation pour le produit, et dont la structure intrinsèque du matériau qui le constitue, autorise la reprise d'air au travers dudit matériau.According to another advantageous embodiment, the shutter member is formed of a porous, elastically deformable material. We thus realize with a single part, an element forming both a shutter member for the product, and of which the intrinsic structure of the material that constitutes it, allows air to be taken in across said material.

A titre d'indication, le matériau poreux élastiquement déformable est constitué d'un fritté de thermoplastique semi-cristallin, notamment un fritté de copolymère d'éthylène et d'acétate de vinyle, ou de polyéthylène très basse densité, ou d'une mousse de polyuréthane à cellules ouvertes, etc.. D'autres matériaux encore peuvent être utilisés.As an indication, the elastically deformable porous material consists of a semi-crystalline thermoplastic sinter, in particular a copolymer sinter ethylene and vinyl acetate, or very low density polyethylene, or a polyurethane foam with open cells, etc. Other materials still can be used.

Le siège peut être constitué d'un matériau rigide ou semi rigide tels que les polyoléfines, notamment les polypropylènes, les polyéthylènes haute densité ou basse densité, ou tels que les chlorures de polyvinyle, etc..The seat can be made of a rigid or semi-rigid material such as polyolefins, in particular polypropylenes, high density polyethylenes or low density, or such as polyvinyl chlorides, etc.

Selon une variante, le siège est constitué d'un matériau poreux tels que les frittés de polyoléfine, notamment de polyéthylène haute densité ou basse densité, les frittés de polypropylène, les frittés de polyéthylène et de polypropylène, les frittés de thermoplastique semi-cristallin, notamment les frittés de copolymère d'éthylène et d'acétate de vinyle, ou de polyéthylène très basse densité, ou tels que les mousses de polyuréthane, etc.. Alternatively, the seat is made of a porous material such as sintered polyolefin, in particular high density or low density polyethylene, the sintered polypropylene, sintered polyethylene and polypropylene, sintered of semi-crystalline thermoplastic, in particular sintered ethylene copolymer and vinyl acetate, or very low density polyethylene, or such as polyurethane foams, etc.

Dans l'hypothèse où l'organe d'obturation est réalisé en un matériau élastiquement déformable, non poreux, celui-ci peut être réalisé en un matériau tels les élastomères naturels, synthétiques ou thermoplastiques, notamment les copolymères de polypropylène et de SEBS, les copolymères de styrène-butadiène ou d'éthylène-vinyl-acétate, les polyéthylènes très basse densité, les caoutchoucs nitriles, le polychloroprène ou néoprène, les terpolymères d'éthylène, de propylène et d'un diène monomère (EPDM), les copolymères de butadiène et d'acrylonitrile, les polyuréthanes, les chlorures de polyvinyle plastifiés, les caoutchoucs réticulés, notamment à base de silicone, etc..In the event that the shutter member is made of a material elastically deformable, non-porous, it can be made of a material such as natural, synthetic or thermoplastic elastomers, in particular polypropylene and SEBS copolymers, styrene-butadiene copolymers or ethylene vinyl acetate, very low density polyethylenes, rubbers nitriles, polychloroprene or neoprene, terpolymers of ethylene, propylene and a diene monomer (EPDM), butadiene copolymers and acrylonitrile, polyurethanes, plasticized polyvinyl chlorides, crosslinked rubbers, in particular based on silicone, etc.

Selon l'invention, on réalise également un ensemble de conditionnement et de distribution comportant un récipient contenant un produit de consistance visqueuse, et surmonté d'une tête de distribution, caractérisé en ce que la tête de distribution est conforme à la présente invention.According to the invention, a packaging and packaging assembly is also produced. distribution comprising a container containing a consistency product viscous, and surmounted by a dispensing head, characterized in that the distribution is in accordance with the present invention.

Le produit peut être un produit cosmétique ou pharmaceutique, notamment une crème, un gel, un lait, une pâte, etc..The product can be a cosmetic or pharmaceutical product, in particular a cream, gel, milk, paste, etc.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • la figure 1 représente un premier mode de réalisation d'une tête de distribution selon l'invention;

Le récipient 1 illustré à la figure 1, est un flacon à parois souples, notamment en un mélange de polyéthylène et de polypropylène, et comprend un corps 2 fermé par un fond et surmonté d'un col 3. Sur le col 3, est montée, notamment par claquage, une tête de distribution 10. La tête de distribution comporte une jupe extérieure 11 formant un habillage, et deux jupes internes 12, 13, définissant entre elles une gorge annulaire 14 destinée à recevoir le bord libre 15 du col 3. La jupe 12 porte un bourrelet de claquage 16 apte à coopérer avec un cordon 17 porté par la surface extérieure du col 3. La coopération des deux jupes 12, 13 assure avec le col un montage étanche de la tête de distribution 10 sur le récipient. La tête 10 présente une ouverture 19 délimitée par un bord 18. Sur le bord 18, est monté en force (ou par tout autre moyen) un organe d'obturation 20, sous forme d'un élément annulaire dont le bord intérieur 21 est libre et délimite un orifice de sortie 29. En position de repos, le bord intérieur 21 est en appui sur un siège central 22. Le siège central 22 forme un dôme, localisé essentiellement dans le col 3 du récipient 1 et dont le sommet est en communication directe avec l'extérieur. Le siège central est porté par des pattes radiales 23 (par exemple, au nombre de trois) dont une extrémité est solidaire du siège 22, et dont l'autre extrémité est solidaire d'un élément annulaire 24 monté en force à l'intérieur de l'ouverture 19. Selon un mode de réalisation particulier, le siège 22 est constitué d'un matériau rigide ou semi rigide, poreux, notamment d'un fritté de polypropylène, de polyéthylène haute densité, ou de polyéthylène basse densité. Alternativement, un matériau plus souple pourrait être utilisé, notamment un fritté de copolymère d'éthylène et d'acétate de vinyle. Dans la pratique, tout matériau étanche au produit contenu dans le récipient, et apte à laisser passer l'air peut être utilisé.The container 1 illustrated in FIG. 1 is a bottle with flexible walls, in particular in a mixture of polyethylene and polypropylene, and comprises a closed body 2 by a bottom and surmounted by a neck 3. On the neck 3, is mounted, in particular by breakdown, a dispensing head 10. The dispensing head comprises a skirt outer 11 forming a covering, and two internal skirts 12, 13, defining between them an annular groove 14 intended to receive the free edge 15 of the neck 3. The skirt 12 carries a snap bead 16 able to cooperate with a cord 17 carried by the outer surface of the collar 3. The cooperation of the two skirts 12, 13 ensures with the neck a tight mounting of the dispensing head 10 on the container. The head 10 has an opening 19 delimited by an edge 18. On the edge 18, is fitted in force (or by any other means) a shutter member 20, in the form of an annular element whose inner edge 21 is free and delimits a outlet orifice 29. In the rest position, the inner edge 21 is supported on a central seat 22. The central seat 22 forms a dome, located essentially in the neck 3 of the container 1 and the top of which is in direct communication with outside. The central seat is carried by radial lugs 23 (for example, at the number of three), one end of which is integral with the seat 22, and the other of which end is integral with an annular element 24 forcibly mounted inside the opening 19. According to a particular embodiment, the seat 22 is constituted a rigid or semi-rigid, porous material, in particular a sintered polypropylene, high density polyethylene, or low density polyethylene. Alternatively, a more flexible material could be used, in particular a sintered material of ethylene and vinyl acetate copolymer. In practice, any material impermeable to the product contained in the container, and capable of allowing air to pass can to be used.

L'organe d'obturation est constitué d'un matériau souple, élastiquement déformable, notamment un copolymère d'éthylène de propylène et d'un diène (EPDM). Pour distribuer une dose de produit, l'utilisatrice exerce une pression sur les parois 24 du récipient 1. Sous la poussée du produit, le bord libre 21 de l'organe d'obturation 20, s'écarte du siège 22 (position représentée en traits pointillés) pour laisser passer le produit au travers de l'orifice de sortie 29 (flèches en traits continus) situé entre le siège et le bord libre ou l'extrémité libre de la membrane élastiquement déformable lorsque celle-ci est en position fléchie. L'utilisatrice peut prélever le produit avec le doigt. Lorsque cesse la pression, le bord libre 21 revient en position sur le siège 22. A ce moment, sous l'effet de la dépression à l'intérieur du récipient 1, de l'air est aspiré dans le flacon en passant au travers des pores du matériau poreux constituant le siège 22, et ce, jusqu'à l'équilibre des pressions (flèches entraits interrompus). On réalise ainsi une fermeture propre, avec un système de reprise d'air formé au niveau de la sortie du produit. L'air est filtré par le matériau poreux, ce qui contribue à protéger le produit, et à le conserver dans des conditions relativement stériles. Un agent antimicrobien peut être contenu dans le matériau poreux de manière à protéger encore davantage le produit.The obturation member is made of a flexible material, elastically deformable, especially a copolymer of ethylene propylene and a diene (EPDM). To dispense a dose of product, the user presses the walls 24 of the container 1. Under the thrust of the product, the free edge 21 of the shutter member 20 moves away from the seat 22 (position shown in lines dotted) to let the product pass through the outlet orifice 29 (arrows in solid lines) located between the seat and the free edge or the free end of the elastically deformable membrane when the latter is in the flexed position. The user can take the product with the finger. When the pressure stops, the free edge 21 returns to position on seat 22. At this time, under the effect of the vacuum inside container 1, air is drawn into the bottle while passing through the pores of the porous material constituting the seat 22, and this, until pressure balance (broken arrows interrupted). We thus realize a clean closure, with an air intake system formed at the outlet of the product. The air is filtered by the porous material, which helps protect the product, and keep it in relatively sterile conditions. An agent antimicrobial may be contained in the porous material so as to protect the product even more.

Un couvercle 25 est prévu pour recouvrir de façon amovible l'ouverture 19. Le couvercle 25 est articulé autour d'un axe 26, et présente une jupe d'étanchéité 27 apte à venir en contact étanche tout autour du bord latéral extérieur 28 formé par l'organe d'obturation 20.A cover 25 is provided for removably covering the opening 19. The cover 25 is articulated around an axis 26, and has a sealing skirt 27 able to come into tight contact all around the outer lateral edge 28 formed by the shutter member 20.

Dans le mode de réalisation de la figure 2, le siège 22 est constitué d'un élément annulaire, dont une portion 30 est surélevée par rapport au bord libre délimitant l'ouverture 19, et émerge par rapport audit bord libre de manière à être en communication directe avec l'extérieur. La portion 30 est légèrement inclinée en direction de l'ouverture. Le siège 22 est monté en force dans l'ouverture 19. L'organe d'obturation 20 est monté par collage, soudure, claquage, ou tout autre moyen sur l'ouverture 19, et présente une extrémité libre formant une lèvre 31 en regard de la partie surélevée 30 du siège 22, ladite lèvre obturant en position de repos, un orifice de sortie 51. Ainsi, sous la pression du produit, la lèvre 31, en appui sur la partie surélevée du siège 22, fléchit par rapport à ce dernier (position représentée en pointillés) pour laisser passer le produit, au travers de l'orifice 51 (flèches en traits continus). Lorsque cesse la pression, la lèvre 31 revient en position d'obturation sur le siège 22. Sous l'effet de la dépression créée à l'intérieur du récipient 1, de l'air est aspiré dans le récipient, via la partie émergente 30 du siège 22 (flèches en traits interrompus).In the embodiment of Figure 2, the seat 22 consists of an element annular, a portion 30 of which is raised relative to the free edge delimiting the opening 19, and emerges with respect to said free edge so as to be in direct communication with the outside. The portion 30 is slightly inclined in opening direction. The seat 22 is forcibly mounted in the opening 19. The shutter member 20 is mounted by gluing, welding, snapping, or any other means on the opening 19, and has a free end forming a lip 31 in look of the raised part 30 of the seat 22, said lip closing in position rest, an outlet orifice 51. Thus, under the pressure of the product, the lip 31, in support on the raised part of the seat 22, flexes relative to the latter (position shown in dotted lines) to allow the product to pass through the orifice 51 (arrows in solid lines). When the pressure stops, the lip 31 returns to shutter position on seat 22. Under the effect of the vacuum created at inside the container 1, air is drawn into the container, via the part emerging from seat 22 (arrows in broken lines).

Dans le mode de réalisation de la figure 3, la tête de distribution 10 est représentée sous forme d'un bouton poussoir 36 apte à surmonter un récipient équipé d'une pompe. A cet effet, la tête de distribution 10 comporte une jupe axiale 32 de diamètre interne adapté pour être monté en force sur une tige de pompe 35. La jupe axiale 32 débouche sur un passage 33, sensiblement perpendiculaire à la jupe axiale 32, lequel passage débouche sur une ouverture 19, à l'intérieur de laquelle est disposé un siège central 22, en matériau poreux. Le siège 22 forme un dôme dont le sommet est en communication directe avec l'extérieur du récipient. Le siège est maintenu dans l'ouverture 19, par montage en force dans un évidement 52 prévu dans la paroi latérale de la jupe axiale 32. L'ouverture 19 est obturée par un organe d'obturation 20, sous forme d'un élément annulaire, élastiquement déformable, monté par claquage à l'intérieur de l'ouverture 19. De la même manière que pour le mode de réalisation de la figure 1, l'organe d'obturation 20 présente un bord intérieur 21 en appui sur le siège 22, et délimitant un orifice de sortie 29. Dans ce mode de réalisation, le siège poreux 22 est constitué d'un fritté de polyéthylène très basse densité. L'organe d'obturation 20 est formée en PVC plastifié. Le fonctionnement de ce mode de réalisation est identique au mode de réalisation de la figure 1, hormis le fait que la sortie du produit sous pression est produite par une pompe à actionnement manuel, dont l'actionnement est commandé en exerçant une pression sur la surface d'appui 34 formée par le bouton poussoir 36.In the embodiment of FIG. 3, the dispensing head 10 is represented in the form of a push button 36 capable of overcoming a container equipped with a pump. To this end, the dispensing head 10 includes a skirt axial 32 of internal diameter adapted to be mounted by force on a rod pump 35. The axial skirt 32 opens onto a passage 33, substantially perpendicular to the axial skirt 32, which passage leads to an opening 19, inside which is disposed a central seat 22, made of porous material. The seat 22 forms a dome, the top of which is in direct communication with the outside of the container. The seat is held in the opening 19, by mounting in force in a recess 52 provided in the side wall of the axial skirt 32. The opening 19 is closed by a shutter member 20, in the form of a annular element, elastically deformable, mounted by snap inside the opening 19. In the same way as for the embodiment of the figure 1, the shutter member 20 has an inner edge 21 bearing on the seat 22, and delimiting an outlet orifice 29. In this embodiment, the porous seat 22 is made of a very low density polyethylene sinter. The organ shutter 20 is formed of plasticized PVC. How this mode works embodiment is identical to the embodiment of Figure 1, except that the pressure product output is produced by an actuating pump manual, actuation of which is controlled by pressing the bearing surface 34 formed by the push button 36.

Dans le mode de réalisation de la figure 4, la tête de distribution 10 se présente sous forme d'un embout 40 permettant une application localisée du produit à distribuer. La surface extérieure du col 3 du récipient 1 présente un filetage 41, apte à coopérer avec un filetage correspondant 42 prévu sur une surface intérieure de l'embout 40. Une jupe intérieure 43 améliore l'étanchéité du montage. L'embout 40 forme un passage axial 44, débouchant sur un orifice de sortie 45 délimité d'une part par une portion de bord 46 formant partie intégrante de l'embout de distribution 40, et s'étendant sur environ 180°. L'embout est réalisé en un matériau souple, notamment un polyéthylène basse densité, de sorte que la portion de bord 46 forme un organe d'obturation élastiquement déformable 20. L'orifice 45 est délimité d'autre part par un élément rapporté 47, en matériau poreux, notamment un fritté de polypropylène, formant un siège 22 pour l'organe d'obturation 20. L'élément rapporté 47 s'étend sur 180°, et peut être soudé ou collé à l'intérieur de l'embout 40. En d'autres termes, l'élément 47 dont la surface extérieure est en contact direct avec l'air environnant, participe en outre à la définition du circuit de sortie du produit, à savoir le passage axial 44. On réduit ainsi la taille du capot ou capuchon destiné, le cas échéant, à améliorer la protection de l'ensemble en position de stockage. Seul l'embout doit être recouvert.In the embodiment of Figure 4, the dispensing head 10 is presented in the form of a nozzle 40 allowing a localized application of the product to distribute. The outer surface of the neck 3 of the container 1 has a thread 41, able to cooperate with a corresponding thread 42 provided on a surface inside of the end piece 40. An inside skirt 43 improves the tightness of the mounting. The end piece 40 forms an axial passage 44, opening onto an orifice of outlet 45 delimited on the one hand by an edge portion 46 forming an integral part of the dispensing nozzle 40, and extending over approximately 180 °. The tip is made in a flexible material, in particular a low density polyethylene, so that the edge portion 46 forms an elastically deformable closure member 20. The orifice 45 is delimited on the other hand by an added element 47, made of material porous, in particular a polypropylene frit, forming a seat 22 for the organ shutter 20. The insert 47 extends over 180 °, and can be welded or glued to the inside of the end piece 40. In other words, the element 47 whose surface outside is in direct contact with the surrounding air, also contributes to the definition of the product outlet circuit, namely the axial passage 44. We reduce thus the size of the hood or cap intended, if necessary, to improve the protection of the assembly in storage position. Only the tip should be covered.

En exerçant une pression sur les parois 24 du récipient, le produit est chassé vers l'orifice de sortie 45, et provoque l'écartement de la partie élastiquement déformable 20, laquelle fléchit pour s'écarter du siège 22 pour laisser passer le produit au travers de l'orifice 45. Le produit peut être appliqué directement de façon localisée sur une surface à traiter. Lorsque cesse la pression, la partie élastiquement déformable 20 revient en appui sur le siège 22, de l'air étant aspiré au travers du matériau poreux formant le siège 22, et ce jusqu'à l'équilibre des pressions.By exerting pressure on the walls 24 of the container, the product is expelled towards the outlet orifice 45, and causes the separation of the part elastically deformable 20, which flexes to move away from the seat 22 to let the product through port 45. The product can be applied directly from localized on a surface to be treated. When the pressure stops, the part elastically deformable 20 comes to rest on the seat 22, air being sucked through the porous material forming the seat 22, until the equilibrium of the pressures.

Selon une variante du mode de réalisation de la figure 4, la portion 46, obtenue de moulage avec l'embout de distribution, est constituée d'un matériau rigide tel qu'un polypropylène, de manière à définir un siège rigide pour la portion 47, élastiquement déformable, faisant office d'organe d'obturation. Dans cette hypothèse, la portion élastiquement déformable est en outre, poreuse, de manière à permettre la reprise d'air à l'intérieur du récipient. A titre d'exemple, la portion 47 est réalisée en fritté de copolymère d'éthylène et d'acétate de vinyle. According to a variant of the embodiment of FIG. 4, the portion 46, obtained from molding with the dispensing nozzle, is made of a rigid material such than polypropylene, so as to define a rigid seat for the portion 47, elastically deformable, acting as a sealing member. In this hypothesis, the elastically deformable portion is also porous, so to allow air to be taken up inside the container. For example, portion 47 is made of sintered copolymer of ethylene and vinyl acetate.

Dans le mode de réalisation de la figure 5, la tête de distribution est de constitution identique à celle décrite en référence à la figure 1. Toutefois, selon ce mode de réalisation, le siège 22 est non poreux, et forme partie intégrante de la tête de distribution, avec laquelle il est obtenu de moulage. A titre d'exemple, la tête de distribution, est réalisée en polypropylène. Selon ce mode de réalisation, l'organe d'obturation 20 est constitué d'un matériau souple, élastiquement déformable, et poreux, de manière à permettre la reprise d'air. A titre d'exemple, on utilise une mousse à cellules ouvertes à base de polyuréthane, un fritté de copolymère d'éthylène et d'acétate de vinyle, ou un fritté de polyéthylène très basse densité. L'organe élastiquement déformable 20 est monté dans l'ouverture 19, soit par collage, ou par soudure. Ainsi, cette fois, lorsque l'organe d'obturation 20 revient en position de fermeture sur le siège 22, la reprise d'air se fait non pas par le siège 22, mais par l'organe d'obturation 20 lui-même, dont une partie est en contact direct avec l'extérieur du récipient, et dont la nature permet le passage de l'air sous l'effet de la dépression présente dans le récipient 1. Ainsi, selon ce mode de réalisation, l'organe de fermeture, assure, outre la fonction d'ouverture et de fermeture du récipient, la fonction de reprise d'air.In the embodiment of Figure 5, the dispensing head is constitution identical to that described with reference to Figure 1. However, according to this embodiment, the seat 22 is non-porous, and forms an integral part of the dispensing head, with which it is obtained from molding. For example, the dispensing head, is made of polypropylene. According to this embodiment, the shutter member 20 is made of a flexible material, elastically deformable, and porous, so as to allow the return of air. For exemple, an open cell foam based on polyurethane, a sintered copolymer of ethylene and vinyl acetate, or a sintered polyethylene low density. The elastically deformable member 20 is mounted in the opening 19, either by gluing, or by welding. So this time when the shutter 20 returns to the closed position on the seat 22, the air intake is not by the seat 22, but by the shutter member 20 itself, part of which is in direct contact with the outside of the container, and the nature of which allows the passage of the air under the effect of the depression present in the container 1. Thus, according to embodiment, the closing member, ensures, in addition to the opening function and the container, the air return function.

En position fermée du couvercle 25, un bord 50, formant partie intégrante du couvercle 25, vient en appui sur l'extrémité libre de l'organe d'obturation 20, de manière à le maintenir plaqué en appui sur le siège 22, améliorant ainsi l'étanchéité à la fermeture.In the closed position of the cover 25, an edge 50, forming an integral part of the cover 25, bears on the free end of the shutter member 20, so as to keep it pressed against the seat 22, thus improving sealing on closing.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the invention as claimed below.
