Description

La présente invention a pour objet un dispositif d'obturation totale et immédiate, adaptable sur des contenants divers, flacons, tubes, pots, rigides ou souples, utilisables dans les domaines de la pharmacie et de la cosmétologie pour des produits liquides ou pâteux.The present invention relates to a total and immediate sealing device, adaptable to various containers, bottles, tubes, jars, rigid or flexible, usable in the fields of pharmacy and cosmetology for liquid or pasty products.

Dans ces domaines, l'utilisation des produits, qu'ils soient liquides ou pâteux, et quel que soit le contenant, nécessite un dispositif d'obturation efficace, afin d'éviter que lesdits produits ne se dessèchent partiellement.In these fields, the use of products, whether liquid or pasty, and whatever the container, requires an effective sealing device, in order to prevent said products from partially drying out.

Les dispositifs d'obturation actuels sont constitués, dans la majorité des cas, d'un simple bouchon que l'on adapte après utilisation sur l'ouverture du contenant, par vissage ou autre moyen de solidarisation.Current closure devices consist, in most cases, of a simple plug which is adapted after use on the opening of the container, by screwing or other means of attachment.

Dans tous les cas l'obturation s'effectue par positionnement d'un bouchon en matière dure sur un contenant en matière dure, ce qui ne permet pas d'obtenir une parfaite herméticité et entraîne le risque d'une dessication partielle du produit.In all cases, the obturation is carried out by positioning a hard material stopper on a hard material container, which does not make it possible to obtain a perfect airtight and entails the risk of partial drying of the product.

La présente invention vise à remédier cet inconvénient en proposant un dispositif de conception simple et d'un coût de fabrication réduit permettant l'obturation totale et immédiate d'un contenant après utilisation.The present invention aims to remedy this drawback by proposing a device of simple design and of a reduced manufacturing cost allowing total and immediate sealing of a container after use.

Le dispositif d'obturation objet de la présente invention comporte un capuchon réalisé en un matériau déformable élastique, adaptable sur l'ouverture du contenant, ledit capuchon étant percé axialement d'une ouverture dans laquelle s'insère étroitement un corps cylindrique de diamètre inférieur à celui de l'ouverture du contenant, dont l'extrémité située du côté dudit contenant pénètre concentriquement dans ladite ouverture, à la paroi intérieure duquel il est solidarisé fermement en plusieurs points de manière qu'un espace soit ménagé entre ledit corps cylindrique et ladite paroi pour permettre le passage du contenu, liquide ou pâteux, dudit contenant.The closure device which is the subject of the present invention comprises a cap made of an elastic deformable material, adaptable to the opening of the container, said cap being pierced axially with an opening in which a cylindrical body of diameter less than that of the opening of the container, the end of which located on the side of said container penetrates concentrically into said opening, to the internal wall from which it is firmly fixed at several points so that a space is provided between said cylindrical body and said wall to allow the passage of the content, liquid or pasty, of said container.

Lorsque l'on met le contenu sous pression, celui-ci exerce une pression sur la paroi de l'ouverture dudit capuchon en matière déformable, qui s'écarte radialement du corps cylindrique central pour laisser sortir ledit contenu. Lorsque la pression sur le contenu est arrêtée, la paroi de l'ouverture du capuchon, du fait de son élasticité, reprend sa position initiale autour du corps cylindrique, obturant le contenant de façon hermétique.When the content is pressurized, it exerts pressure on the wall of the opening of said cap of deformable material, which moves radially from the central cylindrical body to let out said content. When the pressure on the contents is stopped, the wall of the opening of the cap, due to its elasticity, returns to its initial position around the cylindrical body, sealing the container hermetically.

Le matériau déformable élastique utilisé pour réaliser le capuchon du dispositif selon l'invention peut être un caoutchouc naturel, un élastomère, un silicone ou une matière thermoplastique élastique.The elastic deformable material used to make the cap of the device according to the invention can be a natural rubber, an elastomer, a silicone or an elastic thermoplastic material.

A titre d'exemple de matériaux utilisables on peut citer les copolymères butadiène-styrène ou butadièneacrylonitrile, les polymères du chloroprène, les caoutchoucs butyle, les thioplastes, les copolymères éthylène-acrylate d'éthyle ou éthylène-acétate de vinyle, les polyéthers blocs amides, cette énumération n'étant pas limitative.As examples of materials which can be used, mention may be made of butadiene-styrene or butadiene-acrylonitrile copolymers, chloroprene polymers, rubbers butyl, thioplasts, ethylene-ethyl acrylate or ethylene-vinyl acetate copolymers, polyether block amides, this list not being limiting.

Il est à noter que la présente invention, associée à celle décrite dans la demande de brevet 91/03079 au nom des présents demandeurs concernant un dispositif doseur, permet la réalisation d'un dispositif doseur à obturation totale et immédiate susceptible de multiples utilisations, par mise en oeuvre des propriétés d'élasticité et d'étanchéité d'une pièce réalisée en élastomère, en vue d'aspirer le contenu du récipient sur lequel il est adapté.It should be noted that the present invention, associated with that described in patent application 91/03079 in the name of the present applicants concerning a metering device, allows the production of a metering device with total and immediate closure capable of multiple uses, by implementation of the elasticity and sealing properties of a part made of elastomer, with a view to aspirating the contents of the container on which it is adapted.

En donnant à cette pièce la forme, quelque peu modifiée, du capuchon du dispositif d'obturation objet de la présente invention, et en la plaçant en amont dudit capuchon, on obtient un distributeur doseur obturable totalement et immédiatement, de conception simple, ne nécessitant que très peu de pièces comparativement aux dispositifs équivalents actuellement sur le marché. On peut ainsi réaliser des distributeurs de très faibles doses, notamment du type stilligoutte.By giving this part the somewhat modified form of the cap of the closure device which is the subject of the present invention, and by placing it upstream of said cap, there is obtained a metering distributor which can be closed completely and immediately, of simple design, requiring no very few parts compared to equivalent devices currently on the market. It is thus possible to produce dispensers of very low doses, in particular of the stilligoutte type.

Le dispositif d'obturation selon l'invention peut avantageusement être utilisé pour des produits renfermant des composants volatils tels les vernis à ongles, le corps cylindrique central pouvant alors être prolongé par un pinceau en permettant l'application.The closure device according to the invention can advantageously be used for products containing volatile components such as nail varnishes, the central cylindrical body then being able to be extended by a brush allowing the application.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente quelques modes de réalisation non limitatifs.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents some non-limiting embodiments.

Si on se réfère à la figure 1 on peut voir que le dispositif d'obturation 1 selon la présente invention est assemblé à l'extrémité d'un contenant 2 sur l'ouverture 21 de celui-ci. Ce dispositif d'obturation 1 comporte d'une part un capuchon 10 en matière déformable élastique enserrant l'embouchure du contenant et percé axialement d'une ouverture 11, et d'autre part un corps cylindrique 22 solidaire du contenant 2 concentriquement à l'ouverture 21, ce corps cylindrique 22 étant étroitement inséré dans l'ouverture 11 du capuchon 10.Referring to Figure 1 we can see that the closure device 1 according to the present invention is assembled at the end of a container 2 on the opening 21 thereof. This closure device 1 comprises on the one hand a cap 10 of elastic deformable material enclosing the mouth of the container and pierced axially with an opening 11, and on the other hand a cylindrical body 22 integral with the container 2 concentrically with the opening 21, this cylindrical body 22 being tightly inserted into the opening 11 of the cap 10.

Si on se réfère à la figure la on peut voir que le corps cylindrique 22 est solidarisé à la paroi 24 de l'ouverture 21 par l'intermédiaire de ponts 25 régulièrement espacés, maintenant ledit corps cylindrique 22 à une certaine distance de ladite paroi 24.If we refer to Figure la we can see that the cylindrical body 22 is secured to the wall 24 of the opening 21 by means of regularly spaced bridges 25, keeping said cylindrical body 22 at a certain distance from said wall 24.

Si on se réfère maintenant à la figure 2 on peut voir que lorsque l'on applique une pression sur le contenu 23 celui-ci est comprimé, au niveau de l'ouverture 21, sur la zone de contact entre le corps cylindrique 22 et la paroi interne 12 de l'ouverture 11 du capuchon 10.Du fait de la déformabilité du capuchon 10 cette paroi interne 12 se décolle de la surface du corps cylindrique 22, laissant échapper le contenu 23.Referring now to FIG. 2, it can be seen that when a pressure is applied to the contents 23 the latter is compressed, at the level of the opening 21, on the contact zone between the cylindrical body 22 and the internal wall 12 of the opening 11 of the cap 10. Due to the deformability of the cap 10 this internal wall 12 peels off from the surface of the cylindrical body 22, allowing the contents 23 to escape.

Lorsque la pression est relâchée, le capuchon 10 reprend sa forme initiale et obture le contenant 2, le contenu 23 restant à l'abri de l'air.When the pressure is released, the cap 10 returns to its initial shape and closes the container 2, the content 23 remaining sheltered from the air.

Si on se réfère maintenant à la figure 3 on peut voir que le dispositif d'obturation selon l'invention est adaptable à n'importe quel contenant existant, dès lors que celui-ci possède un moyen de solidarisation tel un pas de vis.If we now refer to Figure 3 we can see that the closure device according to the invention is adaptable to any existing container, since it has a securing means such as a thread.

Sur cette figure 3 on peut voir un contenant 4 comportant une ouverture 40 munie extérieurement d'un pas de vis 41 servant initialement à l'obturation au moyen d'un bouchon classique, sur lequel est adapté un dispositif d'obturation 5 comportant un corps extérieur 50, muni d'un pas de vis 51 permettant sa solidarisation au contenant 4, percé axialement d'une ouverture 52 prolongeant l'ouverture 40, et garnie d'un capuchon 53 en matière déformable élastique lui-même percé d'une ouverture 54 dans laquelle est étroitement inséré un corps cylindrique 55 solidaire du corps extérieur 50 et concentrique à l'ouverture 54.In this figure 3 we can see a container 4 having an opening 40 provided externally with a thread 41 used initially for sealing by means of a conventional plug, on which is adapted a sealing device 5 comprising a body exterior 50, provided with a thread 51 allowing it to be secured to container 4, axially pierced with an opening 52 extending the opening 40, and provided with a cap 53 made of elastic deformable material itself pierced with an opening 54 in which is tightly inserted a cylindrical body 55 integral with the external body 50 and concentric with the opening 54.

Si on se réfère maintenant à la figure 4 on peut voir que le dispositif d'obturation 1 peut être associé à un dispositif doseur 6 tel que celui décrit dans la demande de brevet 91/03079.Referring now to FIG. 4, it can be seen that the closure device 1 can be associated with a metering device 6 such as that described in patent application 91/03079.

Ce dispositif doseur 6 est constitué d'une pièce 60 en matière déformable, comportant une partie 61, semblable au capuchon 10, ayant une ouverture 62 dans laquelle s'insère étroitement un cylindre 27 solidaire du contenant 2 et placé concentriquement dans un tube 28, créant un espace annulaire 29 communiquant avec l'intérieur du contenant 2 renfermant le contenu 23. Cette partie 61 est prolongée périphériquement par un corps tubulaire 63 dont l'extrémité inférieure comporte un rebord 64 permettant sa solidarisation au capot 26 du contenant.This metering device 6 consists of a part 60 made of deformable material, comprising a part 61, similar to the cap 10, having an opening 62 in which a cylinder 27 is tightly inserted integral with the container 2 and placed concentrically in a tube 28, creating an annular space 29 communicating with the interior of the container 2 containing the content 23. This part 61 is extended peripherally by a tubular body 63 whose lower end has a flange 64 allowing its attachment to the cover 26 of the container.

De ce fait, sous l'action d'une pression P sur le capot 26, le corps tubulaire 63 de la pièce 60 est étiré, et le produit contenu dans une chambre-doseuse 65 est expulsé vers l'ouverture 21 du contenant 2. Lors du relâchement du capot 26 la partie tubulaire 63 reprend sa forme initiale, entraînant l'aspiration du contenu 23 dans la chambre 65 par l'espace annulaire 29.As a result, under the action of a pressure P on the cover 26, the tubular body 63 of the part 60 is stretched, and the product contained in a metering chamber 65 is expelled towards the opening 21 of the container 2. When the cover 26 is released, the tubular part 63 returns to its initial shape, causing the contents 23 to be drawn into the chamber 65 through the annular space 29.

Un dispositif d'obturation 1 placé en aval de la chambre-doseuse 65 permet que le contenu 23 de cette chambre-doseuse 65 ne soit pas en contact avec l'air extérieur.A closure device 1 placed downstream of the metering chamber 65 allows the contents 23 of this metering chamber 65 not to be in contact with the outside air.

Si on se réfère maintenant à la figure 5 on peut voir que le dispositif d'obturation selon l'invention peut avantageusement être appliqué à un flacon de vernis à ongle.Referring now to FIG. 5, it can be seen that the closure device according to the invention can advantageously be applied to a bottle of nail varnish.

Dans ce mode de réalisation le corps cylindrique 22 du dispositif d'obturation comporte un prolongement 220 émergeant du capuchon 10 et à l'extrémité duquel et périphériquement sont solidarisés les poils 221 d'un pinceau 222.In this embodiment, the cylindrical body 22 of the closure device has an extension 220 emerging from the cap 10 and at the end of which and peripherally are the bristles 221 of a brush 222.

Le capuchon 10 est à sa base replié vers l'extérieur en un prolongement 13 dont l'extrémité vient recouvrir la base des poils 221 et qui ménage un espace annulaire 14 au-dessus de l'ouverture 11 du capuchon 10.The cap 10 is at its base folded outwards in an extension 13 the end of which covers the base of the bristles 221 and which provides an annular space 14 above the opening 11 of the cap 10.

Au niveau de cet espace annulaire 14, le prolongement 220 du corps cylindrique 22 comporte des ouvertures radiales 223 communiquant avec un canal axial 224 débouchant entre les poils 221.At this annular space 14, the extension 220 of the cylindrical body 22 includes radial openings 223 communicating with an axial channel 224 opening out between the bristles 221.

Une pression sur le contenant 2 a pour effet de chasser le contenu 23 par l'ouverture 11 du capuchon 10, ce contenu 23 se répandant dans l'espace annulaire 14 puis s'écoulant dans le canal axial 224 en passant par les ouvertures 223, jusqu'aux poils 221 du pinceau 222.A pressure on the container 2 has the effect of expelling the content 23 through the opening 11 of the cap 10, this content 23 spreading in the annular space 14 then flowing in the axial channel 224 passing through the openings 223, to the bristles 221 of the brush 222.

L'ensemble comprenant le pinceau et le dispositif d'obturation est recouvert d'un capuchon 20 en matière dure, l'herméticité entre ces deux parties étant assurée par le contact entre la paroi interne de ce capuchon 20 en matière dure et la paroi externe à la fois du capuchon 10 et de son prolongement 13, tous deux réalisés en un seul bloc de matière élastique.The assembly comprising the brush and the shutter device is covered with a cap 20 made of hard material, the hermeticity between these two parts being ensured by the contact between the internal wall of this cap 20 made of hard material and the external wall both of the cap 10 and of its extension 13, both made from a single block of elastic material.

Si on se réfère maintenant aux figures 6 et 6a on peut voir sur ces figures un autre dispositif distributeur de vernis à ongle, ou autre produit de même type, dans lequel le dispositif d'obturation 1 est associé au dispositif doseur 6 décrit précédemment, de manière que la distribution du vernis se fasse par pression sur la tête du distributeur, auquel cas le contenant 2 est en matière souple et placé dans une enveloppe rigide 2′ surmontée d'un capuchon 2˝ en matière dure, l'ensemble pouvant présenter la forme et la taille d'un stylo. Dans ce cas il n'est pas nécessaire de distribuer à chaque pression une dose complète, le dispositif doseur étant avant tout utilisé pour pomper le contenu et l'amener jusqu'au pinceau.If we now refer to FIGS. 6 and 6a, we can see in these figures another device for dispensing nail varnish, or other product of the same type, in which the closure device 1 is associated with the dosing device 6 described above, of so that the varnish is dispensed by pressing on the head of the dispenser, in which case the container 2 is made of flexible material and placed in a rigid envelope 2 ′ surmounted by a cap 2˝ of hard material, the assembly possibly having the shape and size of a pen. In this case it is not necessary to dispense a full dose at each press, the metering device being used above all to pump the contents and bring them up to the brush.

Il va de soi que la présente invention ne saurait être limitée à la description qui précède de certains de ses modes de réalisation, susceptibles de subir des modifications sans pour autant sortir du cadre de l'invention.It goes without saying that the present invention cannot be limited to the foregoing description of some of its embodiments, which are capable of being modified without departing from the scope of the invention.
