Description

La présente invention concerne un récipient muni d'un dispositif élastique de fermeture, ledit récipient comportant un canal de sortie du produit à distribuer, l'orifice dudit canal étant fermé par une membrane dont au moins une partie élastique se déforme sous la pression du produit distribué et dégage des ouvertures qui étaient jusqu'alors obturées grâce aux propriétés élastiques de la membrane.The present invention relates to a container provided with an elastic closure device, said container comprising an outlet channel for the product to be dispensed, the orifice of said channel being closed by a membrane of which at least one elastic part is deformed under the pressure of the product. distributes and releases openings that were previously closed thanks to the elastic properties of the membrane.

Il est connu par FR-A-1 092 480 de protéger le produit contenu dans un récipient après la première utilisation, sans que l'utilisateur ait à faire une opération particulière ; pour ce faire, on adapte, sur le col d'un récipient déformable par pression de l'utilisateur sur ses parois (par exemple un tube), une coiffe comportant au moins une partie élastique déformable sous la pression du produit distribué ; la coiffe peut être munie de fentes ou de trous, qui s'ouvrent lors de sa déformation, ou une partie élastique de la coiffe peut former un clapet qui coopère avec un siège rigide. Cependant, l'étanchéité à l'air de ce type de fermeture n'est pas toujours satisfaisante et, en cas de stockage prolongé, il y a fréquemment une rentrée d'air susceptible de provoquer l'altération du produit contenu dans le récipient. Pour améliorer l'étanchéité, on a proposé de recouvrir la coiffe d'un capuchon. Mais, dans ce cas, l'utilisateur doit penser à fixer le capuchon après chaque usage, ce qui lui enlève le bénéfice de l'utilisation d'un dispositif de fermeture élastique.It is known from FR-A-1 092 480 to protect the product contained in a container after the first use, without the user having to do a particular operation; to do this, it adapts, on the neck of a container deformable by pressure of the user on its walls (for example a tube), a cap comprising at least one elastic part deformable under the pressure of the product dispensed; the cap can be provided with slots or holes, which open during its deformation, or an elastic part of the cap can form a valve which cooperates with a rigid seat. However, the airtightness of this type of closure is not always satisfactory and, in the event of prolonged storage, there is frequently an air intake likely to cause the alteration of the product contained in the container. To improve sealing, it has been proposed to cover the cap with a cap. However, in this case, the user must remember to fix the cap after each use, which takes away the benefit of using an elastic closure device.

La présente invention a pour but de fournir un dispositif élastique de fermeture permettant d'obtenir une bonne étanchéité sans qu'il soit nécessaire de le recouvrir par un capuchon après chaque usage.The object of the present invention is to provide an elastic closure device allowing good sealing to be obtained without it being necessary to cover it with a cap after each use.

Le but de la présente invention est atteint en utilisant une membrane comportant à la fois un pointeau obturateur qui ferme l'orifice de sortie du canal et au moins une ouverture qui est fermée lorsque la membrane est en position de fermeture.The object of the present invention is achieved by using a membrane comprising both a shutter needle which closes the outlet orifice of the channel and at least one opening which is closed when the membrane is in the closed position.

La présente invention a, par conséquent, pour objet un récipient muni d'un dispositif élastique de fermeture, ledit récipient comportant un canal de sortie du produit à distribuer, dont l'orifice est fermé par une membrane en matériau élastique dont au moins une partie se déforme sous la pression du produit, lors de sa distribution, et dégage au moins un passage qui était jusqu'alors obturé en raison des propriétés élastiques du matériau de la membrane, caractérisé par le fait que la face de la membrane tournée vers le récipient est munie d'un pointeau obturateur de l'orifice du canal de sortie et que la membrane est munie d'au moins une ouverture susceptible d'assurer la distribution du produit.The present invention therefore relates to a container provided with an elastic closure device, said container comprising an outlet channel for the product to be dispensed, the orifice of which is closed by a membrane of elastic material of which at least part deforms under the pressure of the product, during its distribution, and clears at least one passage which was hitherto closed due to the elastic properties of the membrane material, characterized in that the face of the membrane facing the container is provided with a needle shutter of the orifice of the outlet channel and that the membrane is provided with at least one opening capable of ensuring the distribution of the product.

Le fonctionnement du dispositif élastique de fermeture selon l'invention est assuré de la façon suivante : sous la pression du produit distribué, le pointeau obturateur se dégage de l'orifice du canal de sortie et simultanément la membrane gonfle; lorsque la déformation de la membrane est suffisante, la (ou les) ouverture(s), qui étai(ent) jusqu'alors fermée(s), grâce à l'élasticité de la membrane, s'ouvre(nt) pour dégager un passage par où peut s'écouler le produit à distribuer. Lorsque la pression excercée par le produit cesse, la membrane élastique reprend sa position de repos, la (ou les) ouverture(s) se referme(nt) et le pointeau obturateur revient boucher à nouveau l'orifice du canal de sortie. On voit que, selon l'invention, la membrane élastique assure à elle seule un double système de fermeture qui permet d'obtenir une étanchéité satisfaisante.The functioning of the elastic closure device according to the invention is ensured in the following manner: under the pressure of the dispensed product, the shutter needle emerges from the orifice of the outlet channel and simultaneously the membrane swells; when the deformation of the membrane is sufficient, the opening (s), which was previously closed, thanks to the elasticity of the membrane, opens (s) to release a passage through which the product to be dispensed can flow. When the pressure exerted by the product ceases, the elastic membrane returns to its rest position, the opening (s) close (s) and the shutter needle returns to plug the orifice of the outlet channel again. It can be seen that, according to the invention, the elastic membrane alone provides a double closure system which makes it possible to obtain a satisfactory seal.

Le dispositif élastique de fermeture selon l'invention peut aussi bien être adapté sur un récipient dont la paroi est déformable que sur un récipient pressurisé qui contient un agent propulseur et sur lequel est fixée une tête de distribution comportant le canal de sortie et son orifice.The elastic closure device according to the invention can be adapted as well on a container whose wall is deformable as on a pressurized container which contains a propellant and on which is fixed a dispensing head comprising the outlet channel and its orifice.

La membrane peut être construite en tout matériau élastiquement déformable tel que caoutchouc naturel ou synthétique, caoutchouc de silicone ou en copolymère éthylène-acétate de vinyle (EVA).The membrane can be constructed from any elastically deformable material such as natural or synthetic rubber, silicone rubber or from ethylene-vinyl acetate copolymer (EVA).

Selon un mode de réalisation préféré du dispositif élastique, la membrane est symétrique par rapport à l'axe de poussée du produit à distribuer, le pointeau obturateur étant situé sur cet axe et l′ (ou les) ouverture(s) étant excentrée(s) par rapport à cet axe.According to a preferred embodiment of the elastic device, the membrane is symmetrical with respect to the thrust axis of the product to be dispensed, the shutter needle being located on this axis and the opening (s) being eccentric (s) ) with respect to this axis.

L'orifice de sortie est, de préférence, ménagé dans une pièce en matériau rigide qui sert de siège à la membrane élastique, la membrane recouvrant la totalité de ladite pièce et étant fixée sur la périphérie de ladite pièce.The outlet orifice is preferably formed in a piece of rigid material which serves as a seat for the elastic membrane, the membrane covering the whole of said piece and being fixed to the periphery of said piece.

Le pointeau a, de préférence, une forme conique.The needle preferably has a conical shape.

Les ouvertures peuvent, selon un premier mode de réalisation, être constituées par des microtrous, par exemple percés à l'aide d'une aiguille, ou des fentes de dimension telle que leur bord puisse s'écarter lors de la déformation de la membrane élastique et revenir en contact pratiquement étanche par élasticité lorsque la membrane est en position de fermeture. Selon un autre mode de réalisation, l′ (les) ouverture(s) est (sont) constituée(s) par des trous ou fentes dont le bord coopère avec la surface rigide d'un élément faisant saillie à partir du siège dans lequel est ménagé l'orifice du canal de sortie.The openings can, according to a first embodiment, be constituted by micro-holes, for example drilled using a needle, or slots of dimension such that their edge can move apart during the deformation of the elastic membrane and return to practically sealed contact by elasticity when the membrane is in the closed position. According to another embodiment, the opening (s) is (are) constituted (s) by holes or slots whose edge cooperates with the rigid surface of an element projecting from the seat in which is formed the orifice of the outlet channel.

Le dispositif de fermeture représenté sur la figure 1 est adapté sur un récipient 1 en matériau souple que l'utilisateur peut déformer par pression manuelle sur sa paroi latérale 11. Le récipient contient le produit à distribuer. Il est muni d'un goulot 12 cylindrique constitué de deux parties de diamètres différents 12a et 12b, la partie de plus faible diamètre 12b étant la plus proche de l'extrémité du goulot 12. La partie 12b du goulot 12 est fermée par une pièce en plastique rigide 13 légèrement bombée disposée perpendiculairement à l'axe du goulot. Dans cette pièce 13 a été ménagé un orifice 14. L'orifice 14 est l'orifice du canal de sortie du produit, qui est distribué par le goulot 12 du récipient 1. Selon le mode de réalisation représenté sur les figures 1 à 3, l'orifice 14 a la forme d'un entonnoir dont la partie conique s'ouvre vers l'extérieur.The closure device shown in FIG. 1 is adapted to a container 1 made of flexible material that the user can deform by manual pressure on its side wall 11. The container contains the product to be dispensed. It is provided with a cylindrical neck 12 made up of two parts of different diameters 12 a and 12 b , the part of smaller diameter 12 b being closest to the end of the neck 12. The part 12 b of the neck 12 is closed by a rigid plastic piece 13 slightly curved disposed perpendicular to the axis of the neck. In this part 13 has been formed an orifice 14. The orifice 14 is the orifice of the product outlet channel, which is distributed by the neck 12 of the container 1. According to the embodiment shown in Figures 1 to 3, the orifice 14 has the shape of a funnel whose conical part opens outwards.

La pièce 13 disposée sur le goulot 12 est entièrement recouverte par une membrane 2 en matériau élastique. Cette membrane 2 est fixée sur la périphérie de la pièce 13 par un bourrelet 21 s'emboîtant dans une gorge 15 ménagée sur la paroi externe de la partie 12b du goulot. Sur la face de la membrane 2, qui est en regard de la pièce 13 est disposé un pointeau 22 de forme conique, qui a le même axe que le goulot. Le pointeau 22 a, à sa base, un diamètre égal, au jeu nécessaire près, à celui de la plus grande base de la partie tronconique de l'orifice 14 ménagé dans la pièce 13. Une série de trous 23 sont régulièrement espacés sur un cercle dont le centre est situé sur l'axe du goulot 12 et dont le diamètre est inférieur à celui de la partie 12b du goulot. Ces trous ont été percés à l'aide d'une aiguille.The part 13 placed on the neck 12 is entirely covered by a membrane 2 made of elastic material. This membrane 2 is fixed on the periphery of the part 13 by a bead 21 fitting into a groove 15 formed on the external wall of the part 12 b of the neck. On the face of the membrane 2, which faces the part 13, is arranged a needle 22 of conical shape, which has the same axis as the neck. The needle 22 has, at its base, a diameter equal, apart from the necessary clearance, to that of the largest base of the frustoconical part of the orifice 14 formed in the part 13. A series of holes 23 are regularly spaced on a circle whose center is located on the axis of the neck 12 and whose diameter is less than that of the part 12 b of the neck. These holes were drilled using a needle.

Le fonctionnement du dispositif de fermeture est le suivant. En position de repos (voir figure 1), le pointeau 22 repose de façon étanche dans l'orifice 14 ; la paroi intérieure de la membrane 2 repose entièrement sur la face supérieure de la pièce 13 qui sert par conséquent de siège à ladite membrane. Les trous 23 sont maintenus fermés grâce à l'élasticité de la membrane 2. Lorsque l'utilisateur désire distribuer le produit contenu dans le récipient 1, il appuie manuellement sur la paroi latérale 11 du récipient 1 de façon à le déformer et à faire diminuer son volume interne. Le produit passe dans le goulot 12 et exerce une pression sur le pointeau 22 qui, grâce à l'élasticité de la membrane 2, dégage l'orifice 14. Sous la poussée du produit à distribuer la membrane 2 continue à se déformer et gonfle en créant un espace E entre la membrane 2 et la pièce 13 formant siège (voir figure 2), espace E qui se remplit de produit. Pour finir, la déformation de la membrane 2 provoque l'ouverture des trous 23 (voir figure 3). La distribution du produit commence.The operation of the closing device is as follows. In the rest position (see FIG. 1), the needle 22 rests tightly in the orifice 14; the inner wall of the membrane 2 rests entirely on the upper face of the part 13 which therefore serves as a seat for said membrane. The holes 23 are kept closed thanks to the elasticity of the membrane 2. When the user wishes to distribute the product contained in the container 1, he presses manually on the side wall 11 of the container 1 so as to deform it and reduce its internal volume. The product passes through the neck 12 and exerts a pressure on the needle 22 which, thanks to the elasticity of the membrane 2, releases the orifice 14. Under the pressure of the product to distribute the membrane 2 continues to deform and swells in creating a space E between the membrane 2 and the part 13 forming a seat (see FIG. 2), space E which is filled with product. For finally, the deformation of the membrane 2 causes the holes 23 to open (see FIG. 3). The distribution of the product begins.

Lorsque l'utilisateur cesse d'appuyer sur les parois 11 du récipient 1, les parois reprennent leur forme initiale, il se produit une légère aspiration et le produit cesse d'exercer une pression sur la membrane 2 qui revient à sa position initiale de fermeture par élasticité. Les trous 23 se ferment immédiatement et il n'y a pas de reprise d'air. Le produit n'est donc pas en contact avec l'air au cours du stockage. Le pointeau 22 revient fermer l'orifice 14 et la membrane 2 revient au contact de la pièce 13. Le récipient est à nouveau fermé et peut être stocké, sans risque d'altération par l'air du produit qu'il contient.When the user stops pressing on the walls 11 of the container 1, the walls return to their initial shape, a slight suction is produced and the product ceases to exert pressure on the membrane 2 which returns to its initial closed position by elasticity. The holes 23 close immediately and there is no air intake. The product is therefore not in contact with air during storage. The needle 22 returns to close the orifice 14 and the membrane 2 returns to contact with the part 13. The container is again closed and can be stored, without risk of alteration by the air of the product that it contains.

Dans le mode de réalisation représenté sur les figures 4 à 6, le récipient 101 est identique à celui représenté sur les figures 1 à 3. Dans la description qui suit et sur les figures 4 à 6, les pièces identiques à celles décrites ci-dessus pour les figures 1 à 3 ou ayant la même fonction portent le même numéro augmenté de 100. Le goulot 112 est fermé par une pièce 113 dans laquelle est ménagé l'orifice 114 du canal de sortie du produit distribué par le goulot 112. La pièce 113 est munie d'un téton cylindrique 116. La membrane 102 est fixée sur le goulot par un système d'encliquetage (bourrelet 121 - gorge 115) ; elle porte sur sa face interne un pointeau 122. Une ouverture 123 est ménagée dans la membrane, cette ouverture étant disposée de façon telle et ayant un diamètre tel que le téton 116 puisse pénétrer dans l'ouverture 123 et la boucher.In the embodiment shown in Figures 4 to 6, the container 101 is identical to that shown in Figures 1 to 3. In the following description and in Figures 4 to 6, the parts identical to those described above for FIGS. 1 to 3 or having the same function have the same number increased by 100. The neck 112 is closed by a piece 113 in which is formed the orifice 114 of the outlet channel of the product dispensed by the neck 112. The piece 113 is provided with a cylindrical stud 116. The membrane 102 is fixed to the neck by a latching system (bead 121 - groove 115); it carries on its internal face a needle 122. An opening 123 is formed in the membrane, this opening being arranged in such a way and having a diameter such that the nipple 116 can penetrate into the opening 123 and plug it.

Le fonctionnement du dispositif de fermeture est analogue à celui décrit dans le cas du dispositif des figures 1 à 3. La poussée du produit déforme la membrane 102 de façon à faire d'abord sortir le pointeau 122 de l'orifice 114 (voir figure 5), puis à provoquer la formation d'un espace E entre la membrane 102 et la pièce 113, et pour finir (voir figure 6), à dégager le téton 116 de l'ouverture 123. Lorsque la poussée du produit cesse, la membrane 102 reprend sa place sur la pièce 113, le téton 116 fermant l'ouverture 123 et le pointeau 122 fermant l'orifice 114.The operation of the closure device is analogous to that described in the case of the device in FIGS. 1 to 3. The thrust of the product deforms the membrane 102 so as to first make the needle 122 exit from the orifice 114 (see FIG. 5), then to cause the formation of a space E between the membrane 102 and the part 113, and to finish (see FIG. 6 ), to release the stud 116 from the opening 123. When the thrust of the product stops, the membrane 102 resumes its place on the part 113, the stud 116 closing the opening 123 and the needle 122 closing the orifice 114.

Dans les modes de réalisation représentés sur les figures 7 à 10, le produit à distribuer est contenu dans un récipient pressurisé muni d'une tête de distribution.In the embodiments shown in FIGS. 7 to 10, the product to be dispensed is contained in a pressurized container provided with a dispensing head.

Comme on peut le voir sur la figure 7, le récipient 201 est fermé par une coupelle de valve 211 fixée par un bourrelet de sertissage sur le bord supérieur du récipient 201, une valve 212 étant sertie au centre de la coupelle 211 ; la tige de valve émerge hors de la coupelle. Une tête de distribution 203 est fixée par claquage sur le bourrelet de sertissage par une jupe fixe 231. Une partie mobile 233 formant bouton-poussoir est reliée par une charnière 235 à la jupe 231. La partie mobile 233 comporte un plateau 233a, dont le plan moyen est, dans l'ensemble, perpendiculaire à l'axe de la tige de valve 212. Sur la face inférieure de ce plateau est ménagé un alésage 233b dans lequel peut s'insérer la tige de valve 212 ; la face supérieure dudit plateau comporte une partie plane 233c sur laquelle l'utilisateur peut appuyer pour enfoncer le bouton-poussoir. Sur la face supérieure du plateau 233 est disposé un élément en forme de trompette 236, qui est incliné par rapport à l'axe de la tige de valve 212. Dans cet élément 236 est ménagé un canal 232, qui s'ouvre vers l'extérieur par un orifice 234 de forme tronconique s'évasant vers l'extérieur ; l'autre extrémité du canal 232 débouche dans l'alésage 233b. Sur l'extrémité libre de l'élément en trompette 236 est fixée une membrane élastique 202, la fixation étant effectuée à l'aide d'un retour de la membrane en matériau élastique qui vient se placer sous le bord de l'extrémité libre de l'élément en trompette 236.As can be seen in FIG. 7, the container 201 is closed by a valve cup 211 fixed by a crimping bead on the upper edge of the container 201, a valve 212 being crimped in the center of the cup 211; the valve stem emerges from the cup. A dispensing head 203 is fixed by snap-fastening on the crimping bead by a fixed skirt 231. A mobile part 233 forming a push button is connected by a hinge 235 to the skirt 231. The mobile part 233 comprises a plate 233 a , of which the mean plane is, overall, perpendicular to the axis of the valve stem 212. On the underside of this plate is formed a bore 233 b in which the valve stem 212 can be inserted; the upper face of said plate has a flat part 233 c on which the user can press to depress the push button. On the upper face of the plate 233 is arranged a trumpet-shaped element 236, which is inclined relative to the axis of the valve stem 212. In this element 236 is formed a channel 232, which opens towards the outside by an orifice 234 of frustoconical shape widening towards the outside; the other end of channel 232 leads in bore 233 b . On the free end of the trumpet element 236 is fixed an elastic membrane 202, the fixing being effected by means of a return of the membrane of elastic material which is placed under the edge of the free end of the trumpet element 236.

La face intérieure de la membrane 202 porte un pointeau 222 de forme conique ayant le même axe que le canal 232 et ayant des dimensions telles qu'il puisse coopérer de façon étanche avec l'orifice tronconique 234. Dans le mode de réalisation représenté sur les figures 7 et 8, une série de trous 223 percés à l'aide d'une aiguille, sont disposés sur un cercle, dont le centre est disposé sur l'axe du canal 232.The inner face of the membrane 202 carries a needle 222 of conical shape having the same axis as the channel 232 and having dimensions such that it can cooperate in a sealed manner with the frustoconical orifice 234. In the embodiment shown in the Figures 7 and 8, a series of holes 223 drilled with a needle, are arranged on a circle, the center of which is arranged on the axis of the channel 232.

Le fonctionnement du dispositif de fermeture est le suivant : en position de repos, la membrane 202 repose sur la face externe 236a de l'élément 236 qui constitue le siège de la membrane ; le pointeau 222 ferme de façon étanche l'orifice 234 et les ouvertures 223 sont fermées grâce à l'élasticité de la membrane 202.The operation of the closing device is as follows: in the rest position, the membrane 202 rests on the external face 236 a of the element 236 which constitutes the seat of the membrane; the needle 222 sealingly closes the orifice 234 and the openings 223 are closed thanks to the elasticity of the membrane 202.

Lorsque l'utilisateur désire distribuer le produit contenu dans le récipient 201, il appuie sur le poussoir 233c, provoquant l'enfoncement de la partie mobile 233 et, par conséquent, l'enfoncement de la tige de valve 212. Le produit sous pression contenu dans le récipient 201, sort de la tige de valve 212 et passe dans le canal 232. Il pousse sur le pointeau 222 qui dégage l'orifice 234 grâce à la déformation de la membrane en matériau élastique 202. Sous la poussée du produit, la déformation de la membrane 202 se poursuit et il se forme un espace E entre la membrane et la face externe 236a de l'élément 236 ; pour finir les trous 223 s'ouvrent par distension de la membrane. Le produit est alors distribué par les trous 223.When the user wishes to dispense the product contained in the container 201, he presses the pusher 233 c , causing the sinking of the movable part 233 and, consequently, the sinking of the valve stem 212. The product under pressure contained in the container 201, leaves the valve stem 212 and passes through the channel 232. It pushes on the needle 222 which releases the orifice 234 thanks to the deformation of the membrane of elastic material 202. Under the pressure of the product, the deformation of the membrane 202 continues and a space E is formed between the membrane and the external face 236 a of the element 236; finally the holes 223 open by distension of the membrane. The product is then distributed through holes 223.

Lorsque l'utilisateur cesse d'appuyer sur le poussoir 233c, le produit cesse d'exercer une pression sur la membrane 202 qui revient par élasticité en position de repos.When the user stops pressing the pusher 233 c , the product ceases to exert pressure on the membrane 202 which returns by elasticity to the rest position.

Dans le mode de réalisation illustré sur les figures 9 et 10, le récipient 301 est identique au récipient 201 illustré sur les figures 7 et 8. Dans la suite de la description, les éléments identiques ou ayant la même fonction que les éléments figurant sur les figures 7 et 8 seront désignés par le même chiffre augmenté de 100.In the embodiment illustrated in Figures 9 and 10, the container 301 is identical to the container 201 illustrated in Figures 7 and 8. In the following description, the elements identical or having the same function as the elements appearing on the Figures 7 and 8 will be designated by the same number increased by 100.

La tête de distribution 303 est identique à la tête de distribution 203, à cette différence près que la face extérieure de l'élément 336 en forme de trompette porte un téton cylindrique 338. La membrane 302 est aussi identique à la membrane 202, à cette différence près qu'à la place des trous 223, elle comporte une ouverture 323 ayant un diamètre tel que le téton 338 puisse y pénétrer à contact étanche.The dispensing head 303 is identical to the dispensing head 203, except that the external face of the element 336 in the shape of a trumpet carries a cylindrical stud 338. The membrane 302 is also identical to the membrane 202, except that difference except that instead of the holes 223, it has an opening 323 having a diameter such that the stud 338 can penetrate there in sealed contact.

Le fonctionnement du dispositif de fermeture est analogue à celui décrit pour le mode de réalisation illustré sur les figures 7 et 8, à cette différence près que la déformation de la membrane 302 provoque le désengagement du téton 338 de l'ouverture 323 et que le produit est distribué par l'ouverture 323 ainsi dégagée.The operation of the closure device is analogous to that described for the embodiment illustrated in FIGS. 7 and 8, except that the deformation of the membrane 302 causes the disengagement of the stud 338 from the opening 323 and that the product is distributed through the opening 323 thus released.
