Description

L'invention a pour objet un dispositif de bouchon verseur.The subject of the invention is a pouring plug device.

Elle vise, en particulier, un tel dispositif propre à être utilisé pour le bouchage de récipients du type des bouteilles ou flacons prévus pour renfermer des produits pâteux ou visqueux.It relates, in particular, to such a device suitable for being used for capping receptacles of the type of bottles or flasks intended to contain pasty or viscous products.

Les bouchons de récipients contenant de tels produits doivent satisfaire à des conditions variées, parfois contradictoires, comme être d'une manipulation aisée, d'un faible coût, d'une bonne étanchéité pour éviter l'altération des qualités du produit emballé, tout en permet­tant d'assurer les garanties de sécurité exigées à la fois par les utilisa­teurs des produits eu égard à l'intégrité du contenu du récipient lors de sa première utilisation et en ce qui concerne les fabrications des produits eu égard, également, à la conservation des qualités desdits produits dans le récipient au cours du temps.The caps of containers containing such products must meet various conditions, sometimes contradictory, such as being easy to handle, low cost, good sealing to avoid alteration of the qualities of the packaged product, while making it possible to ensure the guarantees of safety required both by the users of the products having regard to the integrity of the contents of the container during its first use and as regards the manufacturing of the products having regard, also, to the conservation of the qualities of said products in the container over time.

Pour répondre à ces conditions, en particulier à celles men­tionnées ci-dessus, on a déjà proposé des bouchons verseurs comprenant un opercule interne, sous forme d'une membrane qui obture le débouché du récipient d'une part et, d'autre part, une bande de garantie ou d'inviolabilité qui doit être retirée préalablement à la première utilisa­tion du récipient pour donner accès au contenu de celui-ci. Un exemple d'un tel dispositif, plus particulièrement prévu pour satisfaire aux normes imposées par la règlementation concernant le conditionnement de liquides dangereux est décrit dans FR-A-2 565 208. Il prévoit un opercule de fermeture du débouché du récipient moulé d'une pièce avec un organe verseur dont il est arrachable, de sorte que la capsule que comporte le dispositif doit d'abord être retirée du verseur pour permettre l'accès à l'opercule, la capsule ne pouvant pas ainsi être rendue inséparable du verseur. Une telle disposition, à savoir une capsule inséparable du verseur est cependant très intéressante dans de très nombreuses applications, notamment celles qui concernent le condition­ nement de récipients pour produits alimentaires comme, par exemple, et que sans que cette indication ait quelque caractère limitatif que ce soit, des récipients souples pour condiments comme de la moutarde ou du ketchup, etc... ou des produits tels que des shampooings etc...To meet these conditions, in particular those mentioned above, pouring caps have already been proposed comprising an internal seal, in the form of a membrane which closes the opening of the container on the one hand and, on the other hand, a security or tamper-evident strip which must be removed before the first use of the container to give access to its contents. An example of such a device, more particularly intended to meet the standards imposed by the regulations concerning the packaging of dangerous liquids is described in FR-A-2 565 208. It provides a closure for closing the outlet of the molded container of a piece with a pouring member from which it is tear-off, so that the capsule that the device comprises must first be withdrawn from the pourer to allow access to the cover, the capsule cannot thus be made inseparable from the pourer. Such an arrangement, namely a capsule separable from the pourer, is however very advantageous in very many applications, in particular those relating to the condition containers for food products such as, for example, and without this indication having any limiting nature whatsoever, flexible containers for condiments such as mustard or ketchup, etc. or products such as shampoos etc. ...

C'est, précisément, un but de l'invention de fournir un disposi­tif de bouchon verseur perfectionné que satisfasse à toutes les conditions exigées, rappelées ci-dessus, en particulier celle mentionné en dernier lieu.It is, precisely, an object of the invention to provide an improved pouring plug device which satisfies all the required conditions, recalled above, in particular that mentioned last.

C'est, à cet égard, un but de l'invention de fournir un tel dispositif dans lequel le débouché du récipient qu'il équipe soit obturé par un opercule aussi longtemps qu'un premier actionnement n'a pas eu lieu, et qui interdise un tel actionnement tant qu'une bande d'inviola­bilité n'a pas été retirée.It is, in this regard, an object of the invention to provide such a device in which the opening of the container which it equips is closed by a cover as long as a first actuation has not taken place, and which prohibits such activation until a tamper-evident band has been removed.

C'est, aussi, un but de l'invention de fournir un tel dispositif de bouchon-verseur bien approprié pour équiper des récipients pour produits pâteux ou visqueux, par le fait qu'il assure en permanence une certaine protection du contenu du récipient, tout en étant à bou­chage et débouchage simples et sûrs.It is also an object of the invention to provide such a pouring plug device which is very suitable for equipping containers for pasty or viscous products, by the fact that it permanently ensures a certain protection of the contents of the container, while being simple and safe to plug and unclog.

Un dispositif de bouchon verseur selon l'invention, notamment pour un récipient souple du type de ceux destinés à contenir un produit pâteux ou visqueux comportant un bouchon proprement dit conformé suivant un capot muni de moyens de fixation au goulot du récipient et une coiffe ou capsule mobile par rapport audit bouchon proprement dit, ainsi qu'une bande de garantie ou d'inviolabilité reliée de façon arrachable à ladite coiffe et qui coopère avec ledit bouchon proprement dit pour interdire tout mouvement relatif de la coiffe par rapport au bouchon proprement dit aussi longtemps qu'elle n'a pas été arrachée, est caractérisé en ce que la coiffe et le bouchon proprement dit sont munis de moyens complémentaires interdisant la séparation de l'un par rapport à l'autre tout en assurant le guidage du déplacement de la première par rapport au second, le premier déplacement de ladite coiffe par rapport au bouchon proprement dit qui suit l'arrachage de la bande de garantie provoquant le perçage d'un opercule en forme de membrane solidarisé par ses deux faces, d'une part, de l'orifice du débouché du récipient et, d'autre part, du bouchon proprement dit, ce premier actionnement provoquant simultanément dans ladite coiffe le débouchage d'un orifice de sortie du produit contenu dans le récipient.A pourer stopper device according to the invention, in particular for a flexible container of the type of those intended to contain a pasty or viscous product comprising a stopper proper shaped according to a cover provided with means for fixing to the neck of the container and a cap or capsule movable relative to said cap itself, as well as a guarantee or tamper-proof band connected in a detachable manner to said cap and which cooperates with said cap itself to prevent any relative movement of the cap relative to the cap itself as long that it has not been torn off, is characterized in that the cap and the plug proper are provided with complementary means preventing the separation of one from the other while guiding the movement of the first relative to the second, the first movement of said cap relative to the cap itself which follows the tearing of the guarantee strip causing the piercing of a membrane-shaped cover secured by its two faces, on the one hand, of the orifice of the opening of the container and, on the other hand, of the cap properly said, this first actuation simultaneously causing in said cap the opening of an outlet for the product contained in the container.

Dans une forme de réalisation préférée, lesdits moyens com­plémentaires sont constitués le plus simplement par un chemin de came et des têtons de vissage hélicoïdal conjuguées portées, l'une par la coiffe, et les autres par le bouchon proprement dit.In a preferred embodiment, said complementary means consist most simply of a cam track and of helical screwing studs conjugate carried, one by the cap, and the others by the plug itself.

Dans cette même forme de réalisation, on prévoit, selon une autre caractéristique de l'invention, que des lumières soient ménagées dans le sommet du bouchon proprement dit, lesdites lumières, obturées aussi longtemps que l'opercule en forme de membrane n'a pas été percé, servant à livrer passage à des organes de perçage de ladite membrane solides de la coiffe, lors du premier mouvement relatif du bouchon et de la coiffe.In this same embodiment, provision is made, according to another characteristic of the invention, for openings to be made in the top of the plug proper, said openings, closed as long as the membrane-shaped cover has not been pierced, serving to give passage to the piercing members of said solid membrane of the cap, during the first relative movement of the cap and the cap.

Dans une forme d'exécution préférée, l'invention prévoit que le bouchon proprement dit porte, sur sa face de sommet, un doigt dirigé vers l'extérieur du récipient lorsque le bouchon est en place, de hauteur telle que le premier actionnement de la coiffe par rapport au bouchon proprement dit amène l'extrémité dudit doigt distante du bouchon à coopérer avec une pastille d'obturation d'un orifice de ladite coiffe pour provoquer l'arrachage de celle-ci et ainsi former l'orifice de sortie du produit contenu dans le récipient.In a preferred embodiment, the invention provides that the cap itself carries, on its crown face, a finger directed towards the outside of the container when the cap is in place, of a height such that the first actuation of the cap relative to the plug proper causes the end of said finger distant from the cap to cooperate with a sealing plug of an orifice of said cap to cause the tearing of the latter and thus form the outlet for the product contained in the container.

Selon encore une autre caractéristique de l'invention, la face de sommet du bouchon proprement dit qui porte le doigt mentionné ci-dessus, porte également une cheminée coaxiale audit doigt et dont le diamètre est sensiblement celui d'un cercle limitant les lumières ménagées dans ladite face et conformées suivant des parties de couron­nes annulaires.According to yet another characteristic of the invention, the top face of the plug proper which carries the finger mentioned above, also carries a chimney coaxial with said finger and whose diameter is substantially that of a circle limiting the lights made in said face and shaped according to parts of annular rings.

Lorsque les organes de perçage sont ménagés par des poinçons ou analogues prévus aux extrémités d'une jupe qui dépend de la coiffe, on prévoit avantageusement que le diamètre de ladite jupe soit légère­ment inférieur à celui de la cheminée du bouchon proprement dit, favorisant dans une certaine mesure le mouvement de translation/­rotation de la coiffe par rapport au bouchon proprement dit d'une part et, d'autre part, l'étanchéité du bouchage si l'on prévoit sur le bord libre de la coiffe et de la cheminée, respectivement, des bourrelets ou analogues.When the piercing members are formed by punches or the like provided at the ends of a skirt which depends on the cap, provision is advantageously made for the diameter of said skirt to be slightly less than that of the chimney of the plug proper, favoring in a to some extent the translational / rotational movement of the cap relative to the plug proper on the one hand and, on the other hand, the sealing of the plugging if provided on the free edge of the cap and the chimney, respectively, of the beads or the like.

L'invention sera mieux comprise par la description qui suit, faite à titre d'exemple, et en référence aux dessins annexés dans lesquels :

On se réfère d'abord aux figures 1 à 5 qui illustrent la structure d'un dispositif selon l'invention, destiné à équiper un récipient R, du type de ceux à parois souples et prévu pour enfermer un produit pâteux ou visqueux. Il comprend essentiellement un bouchon proprement dit 10, figures 2 et 3 et une coiffe ou capsule 11, figures 4 et 5. Le bouchon 10 proprement dit en matière plastique du type PPO 2, par exemple, est moulé suivant un corps cylindrique 12, présentant sur sa face interne un filetage 13 destiné à coopérer avec le filetage conjugé du col C du récipient R, et une paroi plane d'extrémité 15 reliée au corps 12 par un pli ou épaulement 14. La paroi 15 est percée d'au moins deux lumières opposées 16 et 17 ayant en plan quelque peu la forme d'une partie de couronne et entre lesquelles est érigé, en saillie sur la face externe 18 de la paroi 15, un doigt creux 19 dirigé à l'opposé du corps 12 par rapport à ladite paroi 15. De cette dernière, fait également saillie, une cheminée 20 coaxiale au doigt 19, dont le diamètre est sensiblement celui du cercle limitant les lumières 16 et 17 sur leur périphérie externe et qui présente à son extrémité libre et sur sa face interne un léger bourrelet 20a.Reference is first made to FIGS. 1 to 5 which illustrate the structure of a device according to the invention, intended to equip a container R, of the type of those with flexible walls and intended to enclose a pasty or viscous product. It essentially comprises a plug proper 10, FIGS. 2 and 3 and a cap or capsule 11, FIGS. 4 and 5. The plug 10 proper of PPO type plastic 2, for example, is molded according to a cylindrical body 12, having on its internal face a thread 13 intended to cooperate with the conjugate thread of the neck C of the container R, and a flat end wall 15 connected to the body 12 by a fold or shoulder 14. The wall 15 is pierced with at least two opposite openings 16 and 17 having in plan somewhat the shape of a part of a crown and between which there is erected, projecting from the external face 18 of the wall 15, a hollow finger 19 directed opposite the body 12 with respect to to said wall 15. From the latter, also protrudes, a chimney 20 coaxial with the finger 19, the diameter of which is substantially that of the circle limiting the openings 16 and 17 on their external periphery and which has at its free end and on its face int erne a slight bead 20a.

A son extrémité distante de celle de raccord à la paroi 15 le corps 12 est conformé suivant une jupe tronconique 25, ménageant sur sa face externe une zone d'appui plane 26 reliée à la face externe 27 dudit corps par un pan coupé 28 et sur sa face interne 29 présente une denture, du type crémaillère, non représentée, propre à coopérer avec une denture correspondante, également non représentée, du col C du récipient R pour s'opposer à l'enlèvement du bouchon proprement dit par rapport audit récipient lequel, préalablement à la mise en place du bouchon proprement dit et après remplissage est obturé à son débouché par un opercule 30, avantageusement une membrane thermo-scellée sur la face plane d'extrémité 31 du col C.At its end distant from that of connection to the wall 15, the body 12 is shaped according to a frustoconical skirt 25, providing on its external face a planar support zone 26 connected to the external face 27 of said body by a cutaway 28 and on its internal face 29 has a toothing, of the rack type, not shown, adapted to cooperate with a corresponding toothing, also not shown, of the neck C of the container R to oppose the removal of the plug proper with respect to said container which , prior to the establishment of the plug proper and after filling is closed at its outlet by a cover 30, advantageously a thermosealed membrane on the flat end face 31 of the neck C.

Avec le bouchon 10 proprement dit est propre à coopérer la coiffe ou capsule 11, figures 4 et 5 et qui, dans la forme de réalisa­tion décrite et représentée, comprend un corps cylindrique 40 sur la face interne 41 duquel sont ménagées des chemins de came 42 dont une est montrée sur la figure 4, lesits chemins de came s'étendant à partir d'une gorge circulaire 42a ménagée au voisinage du bord libre du corps et étant prévues pour coopérer avec au moins deux têtons 45 et 46 de formes et de dimensions conjugées prévues en des zones equidistantes sur la surface externe 27 du corps 12 du bouchon 10 proprement dit.With the plug 10 proper is suitable for cooperating the cap or capsule 11, Figures 4 and 5 and which, in the embodiment described and shown, comprises a cylindrical body 40 on the inner face 41 of which are cam tracks 42 one of which is shown in FIG. 4, said cam paths extending from a circular groove 42a formed in the vicinity of the free edge of the body and being designed to cooperate with at least two pins 45 and 46 of shapes and dimensions conjugates provided in equidistant zones on the external surface 27 of the body 12 of the plug 10 proper.

A l'extrémité libre du corps 40 de la coiffe 11 est attachée une bande d'inviolabilité 50 dont une extrémité présente une languette 51 de préhension permettant l'arrachage facile de ladite languette par rapport au corps 40 auquel elle est reliée par une zone 52 de très faible épaisseur ou par des pontets, la hauteur de ladite bande 50, comme mesurée parallèlement à l'axe A du dispositif, étant sensiblement égale à la distance qui sépare le bord inférieur circulaire 53 du corps 40 de la face d'appui 26 du bouchon proprement dit lorsque celui-ci et la coiffe sont solidarisés entre eux, dans une première condition du bouchon verseur qui est celle montrée sur la figure 1 et qui corres­pond à celle de sortie de l'usine de conditionement, c'est-à-dire en particulier avec l'opercule 30 intact et les têtons 45 et 46 dans la gorge 42a.At the free end of the body 40 of the cap 11 is attached a tamper-evident band 50, one end of which has a gripping tongue 51 allowing the easy pulling of said tongue relative to the body 40 to which it is connected by a zone 52 very thin or with bridges, the height of said strip 50, as measured parallel to the axis A of the device, being substantially equal to the distance between the circular lower edge 53 of the body 40 of the bearing face 26 of the plug proper when the latter and the cap are secured to each other, in a first condition of the pouring plug which is that shown in FIG. 1 and which corresponds to that on leaving the packaging plant, that is to say say in particular with the cover 30 intact and the pins 45 and 46 in the groove 42a.

A son extrémité distante de celle à laquelle est initialement attachée la bande de garantie 50, le corps 40 se poursuit par une partie tronconique 60 laquelle se termine par une paroi 61 sensiblement ortho­gonale à l'axe A du dispositif et dont la zone centrale est découpée suivant des arcs de cercle, comme montrés en 62, 63 et 64 sur la figure 5 pour ménager une pastille centrale 70 reliée au reste de la paroi par des pontets 65, 66, 67, de faible épaisseur et faciles à briser lorsqu'une force dirigée dans le sens de la flèche F est appliquée par le doigt 19 sur ladite pastille.At its end distant from that at which is initially attached to the guarantee strip 50, the body 40 continues with a frusto-conical part 60 which ends in a wall 61 substantially orthogonal to the axis A of the device and the central zone of which is cut along arcs of a circle, as shown at 62 , 63 and 64 in Figure 5 to provide a central patch 70 connected to the rest of the wall by bridges 65, 66, 67, thin and easy to break when a force directed in the direction of arrow F is applied by finger 19 on said patch.

De la paroi 61 dépend, vers l'intérieur de la coiffe, une jupe 71 d'un diamètre externe correspondant sensiblement au diamètre interne de cheminée 20 et qui, à son extrémité libre, présente un léger bourrelet 71a, analogue au bourrelet 20a de la cheminée 20. La jupe 71 est aussi conformée, sur son bord libre 72, suivant au moins deux poinçons 73 opposés comportant chacun une pointe 74 et qui, lorsque le dispositif est assemblé, sont en regard des lumières 16 et 17 du bouchon 10 proprement dit, alors masquées par l'opercule 30.From the wall 61 depends, towards the inside of the cap, a skirt 71 with an external diameter corresponding substantially to the internal diameter of the chimney 20 and which, at its free end, has a slight bead 71a, similar to the bead 20a of the chimney 20. The skirt 71 is also shaped, on its free edge 72, along at least two opposite punches 73 each comprising a point 74 and which, when the device is assembled, are opposite the slots 16 and 17 of the plug 10 proper , then masked by the cover 30.

Le fonctionnement du dispositif selon l'invention résulte immédiatement de ce qui précède.The operation of the device according to the invention results immediately from the above.

Après remplissage du récipient R par le produit qu'il est destiné à contenir, l'opercule 30 est thermoscellé sur le débouché du récipient dans le cas du thermoscellage par conduction et l'ensemble du dispositif, c'est-à-dire le bouchon 10 proprement dit et la coiffe 11, est rapporté sur le col C du récipient par vissage. Lors du thermo­scellage par induction, l'ensemble bouchon/opercule est, après remplis­sage, vissé sur le facon et thermoscellé. Lorsque, à partir de cette condition, on souhaite utiliser le récipient pour la première fois, on procède d'abord à l'arrachage de la bande d'inviolabilité 50, par une simple traction sur la languette 51. Il n'existe alors plus d'obstacle au mouvement relatif de la coiffe par rapport au bouchon proprement dit et l'on peut alors percer l'opercule 30 en déplaçant la coiffe 11 par rapport au bouchon proprement dit, en faisant progresser la coiffe par un mouvement hélicoïdal qui fait coopérer les chemins de came 42 et les têtons 45 et 46 jusqu'à amener ladite coiffe dans la position montrée sur la partie gauche de la figure 6. Au cours de ce mouvement, les poinçons 73 perforent l'opercule 30 et le découpent sensiblement suivant la périphérie des lumières 16, 17.After filling the container R with the product it is intended to contain, the cover 30 is heat sealed on the opening of the container in the case of conduction heat sealing and the entire device, that is to say the cap. 10 proper and the cap 11, is attached to the neck C of the container by screwing. During induction heat sealing, the cap / seal assembly is, after filling, screwed onto the mold and heat sealed. When, from this condition, it is desired to use the container for the first time, the first step is to tear off the tamper-evident band 50, by a simple pull on the tab 51. There then no longer exists obstacle to the relative movement of the cap relative to the cap itself and one can then pierce the cover 30 by moving the cap 11 relative to the cap itself, by advancing the cap by a helical movement which makes cooperate the cam tracks 42 and the pins 45 and 46 until bringing said cap in the position shown on the left-hand side of FIG. 6. During this movement, the punches 73 perforate the cover 30 and cut it out substantially along the periphery of the lights 16, 17.

Simultanément, au cours de ce premier actionnement, la coopération du doigt 19 et de la pastille 70 de la paroi 61 provoque la rupture des pontets 65, 66 et 67 pour former l'orifice de sortie O du produit, comme montré sur la partie droite de la figure 6 où le trajet de sortie du produit est montré par la flèche en pointillés T à partir du récipient, au travers des lumières 16, 17, dans l'espace ménagé entre le doigt 19 et la jupe 71, jusqu'à l'orifice O.Simultaneously, during this first actuation, the cooperation of the finger 19 and the patch 70 of the wall 61 causes the bridges 65, 66 and 67 to rupture to form the outlet orifice O of the product, as shown on the right side in Figure 6 where the product outlet path is shown by the dotted arrow T from the container, through the slots 16, 17, in the space between the finger 19 and the skirt 71, up to l orifice O.

Lorsque, après utilisation du récipient, celui-ci doit être rebouché, un actionnement inverse de la coiffe par rapport au bouchon assure la fermeture, c'est-à-dire le retour dans la condition montrée sur la partie gauche de la figure 6.When, after use of the container, it must be capped, an inverse actuation of the cap relative to the cap ensures the closure, that is to say the return to the condition shown on the left side of FIG. 6.

La présence des bourrelets 71a et 20a qui coopèrent avec la cheminée 20 et la jupe 71, respectivement, contribue à la bonne étanchéité.The presence of the beads 71a and 20a which cooperate with the chimney 20 and the skirt 71, respectively, contributes to good sealing.
