Description

La présente invention concerne un bouchon, notamment pour flacon ou récipient à goulot, pourvu d'une fermeture à clapet coulissant. Plus particulièrement, elle concerne un bouchon pour un goulot fileté ou prévu pour s'enclencher de manière étanche sur ce dernier, ce bouchon étant pourvu d'un orifice de versement pouvant être fermé de manière étanche et ouvert de façon à fournir un débit variable à la demande, par le déplacement en glissement d'un clapet maintenu plaqué sur lui par l'intermédiaire d'une glissière et d'une plaque de couvercle fendue, ce clapet étant pourvu d'une partie plissée arrière, solidaire de cette plaque fendue du côté opposé à l'orifice de versement, et adaptée pour le maintenir en position de fermeture.The present invention relates to a stopper, in particular for a bottle or a container with a neck, provided with a sliding valve closure. More particularly, it relates to a stopper for a threaded neck or intended to engage in a leaktight manner on the latter, this stopper being provided with a pouring orifice which can be closed in a leaktight manner and open so as to provide a variable flow to the request, by the sliding movement of a valve kept pressed against it by means of a slide and a slotted cover plate, this valve being provided with a pleated rear part, integral with this slotted plate side opposite to the pouring orifice, and adapted to keep it in the closed position.

Dans la technique actuelle appliquée pour le bouchage de flacons ou récipients à goulot, destinés à contenir notamment des produits cosmétiques liquides ou des produits en poudre, on connait de nombreux types de bouchons qui comportent un petit orifice rond de déversement, permettant de libérer le contenant du flacon ou récipient considéré, en général sous forme d'un filet dont le débit ne varie pas, cet orifice pouvant être ouvert ou fermé à la demande par le basculage d'un clapet monté sur charnière et constituant bien souvent le capsulage sur bouchon.In the current technique applied for the closure of bottles or containers with necks, intended to contain in particular liquid cosmetic products or powdered products, many types of caps are known which have a small round pouring orifice, making it possible to release the container. of the bottle or container considered, in general in the form of a net, the flow rate of which does not vary, this orifice being able to be opened or closed on demand by tilting a valve mounted on a hinge and very often constituting the capping on a cap.

Ces types de bouchons connus sont pour la plupart critiqués par les utilisateurs, en général pour trois raisons principales, la dimension de l'orifice de versement qui est trop faible si bien que celui-ci s'engorge rapidement, l'impossibilité de faire varier le débit du produit contenu, et l'étanchéité précaire de la fermeture qui occasionne des dépôts de produit, lesquels provoquent des difficultés à l'utilisateur pour l'ouvrir à nouveau et/ou la fermer.These types of known plugs are mostly criticized by users, in general for three main reasons, the dimension of the pouring orifice which is too small so that it becomes quickly engorged, the impossibility of varying the flow of the product contained, and the precarious tightness of the closure which causes deposits of product, which cause difficulties for the user to open it again and / or close it.

On connait également des bouchons avec fermeture à clapet coulissant correspondant au préambule de la revendication 1, tel que celui décrit, par exemple, dans le brevet US-A 3 792 803 (KESSLER). Ce bouchon est adapté pour se fixer sur un flacon ou un récipient à goulot, de manière classique, par filetage ou enclenchement forcé et comporte un orifice de versement de forte taille pratiqué dans son dessus, lequel est pourvu d'une fermeture sous forme d'un clapet plaqué sur cet orifice, ce clapet étant constitué par une languette dont l'extrémité libre avant est adaptée pour pouvoir glisser longitudinalement en étant guidée et forcée en pression sur l'orifice par des glissières latérales à celui-ci, cette languette étant maintenue en position de fermeture par un élément élastique disposé transversalement dans sa partie médiane et ancré à ses deux extrémités latérales au-delà des glissières dans le dessus du bouchon.There are also known plugs with sliding valve closure corresponding to the preamble of claim 1, such as that described, for example, in US-A 3,792,803 (KESSLER). This stopper is suitable for fixing to a bottle or a container with a neck, in a conventional manner, by threading or forced engagement and comprises a large pouring orifice practiced in its top, which is provided with a closure in the form of a valve plated on this orifice, this valve being constituted by a tongue, the front free end of which is adapted to be able to slide longitudinally while being guided and forced into pressure on the orifice by lateral slides to the latter, this tongue being maintained in the closed position by an elastic element arranged transversely in its middle part and anchored at its two lateral ends beyond the slides in the top of the stopper.

On connait également, par le brevet DE- A 3 336 274 (LIBIT) un bouchon avec fermeture à clapet coulissant. Ce bouchon est constitué de trois pièces moulées séparément, le corps du bouchon proprement dit, la languette coulissante constituant le clapet, et un élément élastique de rappel de celle-ci en position de fermeture.We also know, from patent DE-A 3,336,274 (LIBIT) a plug with sliding valve closure. This plug consists of three parts molded separately, the body of the plug proper, the sliding tab constituting the valve, and an elastic return member thereof in the closed position.

Ces deux bouchons connus de la technique antérieure présentent certains inconvénients en ce sens que les diverses pièces qui les composent sont fabriquées séparément et doivent été assemblées pour rendre les bouchons utilisables sur des récipients, d'où un temps de fabrication et de montage assez onéreux et, par ailleurs, rien n'est prévu pour maintenir le clapet coulissant ou languette dans ses glissières latérales, mis à part leur forme en biseau, si bien qu'après un certain temps d'utilisation, suite à des dépôts de produit possibles autour de l'orifice de versement, le clapet tend à sortir de ses glissières et n'assure plus une fermeture étanche.These two plugs known from the prior art have certain drawbacks in the sense that the various parts that compose them are manufactured separately and must be assembled to make the plugs usable on containers, hence a fairly expensive manufacturing and assembly time and , moreover, nothing is provided to maintain the sliding valve or tongue in its lateral slides, apart from their bevelled shape, so that after a certain time of use, following possible deposits of product around the pouring orifice, the valve tends to come out of its slides and no longer ensures a tight closure.

En conséquence, l'un des buts de l'invention est de fournir un bouchon avec fermeture à clapet coulissant qui élimine, par sa constitution, la majeure partie des inconvénients évoqués précédemment des bouchons de ce type, connus dans la technique antérieure et que, pour ce faire, il soit pourvu d'une partie supérieure d'appui et de maintien du clapet coulissant dans ses glissières et, de plus, qui puisse être fabriqué en une seule pièce moulée, si bien que pour son utilisation il sera seulement nécessaire de basculer ladite partie supérieure sur le dessus du corps du bouchon et de forcer sur elle pour engager le clapet dans ses glissières et enclencher la périphérie de cette partie supérieure dans un rebord périphérique correspondant du dessus du corps du bouchon.Consequently, one of the objects of the invention is to provide a stopper with sliding valve closure which eliminates, by its constitution, most of the drawbacks mentioned above of stoppers of this type, known in the prior art and which, to do this, it is provided with an upper part for supporting and holding the sliding valve in its slides and, moreover, which can be manufactured in a single molded part, so that for its use it will only be necessary to tilt said upper part on top of the body of the plug and force on it to engage the valve in its slides and engage the periphery of this upper part in a corresponding peripheral rim of the top of the body of the plug.

Conformément à la présente invention, un tel bouchon avec fermeture à clapet coulissant, fabriqué par moulage en une seule pièce, est remarquable en ce que l'extrémité arrière de la languette formant le clapet est pourvue d'une partie plissée en accordéon, et en ce que sa paroi de dessus est surmontée par une plaque de couvercle sous forme d'une plaque fendue dont la fente en forme de U a des bords latéraux longitudinaux adaptés pour maintenir la languette dans les glissières latérales sans gêner son coulissement, la largeur transversale de cette fente étant prévue pour permettre à un doigt d'en- trainer la languette en coulissement d'ouverture ou de fermeture de l'orifice de versement et étant conçue de largeur légérement moindre que celle de la languette et de la partie plissée, laquelle est située dans le prolongement de cette languette et fait corps avec elle du côté opposé à l'orifice de versement, l'extrémité fermée ou fond de la fente donnant naissance à l'autre extrémité de cette partie plissée, laquelle est située dans un plan horizontal en position de repos en ayant ses plis disposés transversalement et perpendiculairement à l'axe longitudinal de la languette et étant adaptée pour maintenir cette dernière en position de fermeture sans tendre à la remener en arrière.According to the present invention, such a cap with sliding valve closure, produced by molding in one piece, is remarkable in that the rear end of the tongue forming the valve is provided with an accordion-pleated part, and in that its top wall is surmounted by a cover plate in the form of a slit plate whose U-shaped slot has longitudinal lateral edges adapted to hold the tongue in the side rails without hindering its sliding, the transverse width of this slot being provided to allow a finger to entrain the tongue in sliding opening or closing of the pouring orifice and being designed of width slightly less than that of the tongue and of the pleated part, which is located in the extension of this tab and is integral with it on the side opposite to the pouring orifice, the closed end or bottom of the slot giving rise ssance at the other end of this pleated part, which is located in a horizontal plane in the rest position by having its folds arranged transversely and perpendicular to the longitudinal axis of the tongue and being adapted to maintain the latter in the closed position without tend to bring it back.

Par ailleurs, ladite plaque de couvercle sous forme de plaque fendue fait corps avec la paroi de dessus par une partie de charnière située dans le prolongement de la fente et écartée de l'extrémité fermée de celle-ci, qui fait corps avec l'extrémité correspondante de la partie plissée, cette plaque fendue, outre sa partie de charnière, étant enclenchée à force par son bord périphérique, dans un rebord d'enclenchement, saillant vers le haut, sur la périphérie de ladite paroi de dessus.Furthermore, said cover plate in the form of a split plate forms a body with the top wall by a hinge part situated in the extension of the slot and separated from the closed end of the latter, which forms a body with the end corresponding to the pleated part, this split plate, in addition to its hinge part, being forcibly engaged by its peripheral edge, in an interlocking rim, projecting upward, on the periphery of said top wall.

En outre, cette plaque de couvercle sous forme de plaque fendue, la languette coulissante avec sa partie plissée, ainsi que la ou les jupes extérieure et intérieure et la paroi de dessus du bouchon sont fabriquées par moulage en une seule pièce avec la plaque fendue dans sa position déclenchée du rebord d'enclenchement, la mise en position d'utilisation de ce bouchon après démoulage ne nécessitant que la mise en position enclenchée de cette plaque fendue au-dessus de la paroi de dessus.In addition, this cover plate in the form of a split plate, the sliding tab with its pleated part, as well as the outer and inner skirt (s) and the top wall of the cap are produced by molding in one piece with the split plate in its triggered position of the interlocking rim, the placing in the position of use of this plug after demolding only requiring the positioning in the engaged position of this slit plate above the top wall.

En définitive, pour assurer à ce bouchon, avant utilisation, une certaine inviolabilité, l'extrémité libre de la languette est pourvue d'une patte anti-recul de celle-ci, destinée à être arrachée ou coupée pour permettre l'action d'ouverture.Ultimately, to ensure that this plug, before use, a certain inviolability, the free end of the tongue is provided with an anti-recoil tab thereof, intended to be torn off or cut to allow the action of opening.

D'autres caractéristiques de l'invention apparai- tront de la description suivante d'un mode de réalisation de ce bouchon, donné à titre d'exemple non limitatif, et représenté schématiquement dans les dessins ci-joints, dans lesquels:

  • - la figure 1 est une vue en coupe et en élévation du bouchon, prise dans l'axe médian longitudinal à la languette formant le clapet coulissant;
  • - la figure 2 est une vue en plan du dessus du bouchon représenté dans la figure 1;
  • - la figure 3 est une vue en perspective du bouchon représenté dans les figures 1 et 2, alors qu'il est en position de démoulage en une seule pièce, avant le basculage et l'enclenchement de sa partie de couvercle sur sa paroi de dessus, provoquant la mise en place de la languette dans les glissières.
Other characteristics of the invention will appear from the following description of an embodiment of this plug, given by way of nonlimiting example, and represented schematically in the attached drawings, in which:
  • - Figure 1 is a sectional view in elevation of the plug, taken in the longitudinal median axis with the tongue forming the sliding valve;
  • - Figure 2 is a top plan view of the plug shown in Figure 1;
  • - Figure 3 is a perspective view of the plug shown in Figures 1 and 2, while it is in the mold release position in one piece, before the tilting and engagement of its cover portion on its top wall , causing the tongue to fit into the slides.

Comme on le remarque de ces figures, le bouchon conforme à l'invention, représenté schématiquement, est du type classique à enclenchement forcé sur le goulot d'un flacon ou d'un récipient et, pour ce faire, comporte une jupe extérieure 1 et une jupe intérieure 2 au goulot. Ce bouchon est pourvu d'un orifice de versement 3 rond, situé dans sa paroi de dessus 4 et fermé par le clapet 5 adapté pour pouvoir glisser longitudinalement. Ce clapet est constitué par une partie de languette 6, pourvue de saillies supérieures 20 de prise digitale, et une partie arrière 7 plissée en forme d'accordeon. La partie de languette 6 est pourvue latéralement de lévres 9 en forme de biseau, adaptées pour se loger et glisser dans des glissières 10 prévues encastrées dans la paroi de dessus 4 du bouchon. La partie de languette 6 est pourvue inférieurement d'une faible protubérance 12 ayant la forme de l'orifice de versement 3 et destinée à s'engager dans celui-ci lorsque le clapet 5 est en position de fermeture. La paroi de dessus 4 du bouchon est pourvue sensiblement périphériquement, d'un rebord 21 saillant vers le haut et adapté pour permettre l'enclenchement du bord d'une plaque de couvercle sous forme d'une plaque fendue 22 supérieure. Cette plaque fendue est adaptée pour maintenir la partie de languette 6 engagée dans les glissières 10 et empêcher la partie plissée 7 de se relever lors d'une manoeuvre digitale d'ouverture du clapet 5. Pour ce faire, la fente 23 de cette plaque 22 est prévue de largeur légérement moindre que celle de la partie de languette 6 et de la partie plissée 7.As can be seen from these figures, the stopper according to the invention, shown diagrammatically, is of the conventional type with forced engagement on the neck of a bottle or container and, to do this, comprises an outer skirt 1 and an interior skirt 2 at the neck. This plug is provided with a round pouring orifice 3, located in its top wall 4 and closed by the valve 5 adapted to be able to slide longitudinally. This valve is constituted by a tongue part 6, provided with upper projections 20 for digital grip, and a rear part 7 pleated in the form of an accordion. The tongue portion 6 is provided laterally with bevelled lips 9, adapted to be housed and slide in slides 10 provided embedded in the top wall 4 of the plug. The tongue part 6 is provided below with a small protuberance 12 having the shape of the pouring orifice 3 and intended to engage therein when the valve 5 is in the closed position. The top wall 4 of the plug is provided substantially peripherally with a rim 21 projecting upwards and adapted to allow the engagement of the edge of a cover plate in the form of a split slit plate 22 above. This slotted plate is adapted to keep the tongue part 6 engaged in the slides 10 and prevent the pleated part 7 from rising up during a digital operation of opening the valve 5. To do this, the slot 23 of this plate 22 is provided with a width slightly less than that of the tongue part 6 and of the pleated part 7.

On doit noter également, comme on le voit au mieux dans la figure 3, représentant le bouchon en position de démoulage, que l'extrémité arrière 24 de la partie plissée 7 prend naissance et est solidaire du fond de la fente 23 de la plaque 22, laquelle est prévue solidaire du dessus 4 du bouchon par une partie de charnière 25.It should also be noted, as best seen in Figure 3, showing the plug in the release position, that the rear end 24 of the pleated part 7 arises and is integral with the bottom of the slot 23 of the plate 22 , which is provided integral with the top 4 of the plug by a hinge part 25.

En outre afin d'assurer une sorte d'inviolabilité de la fermeture avant utilisation, l'extrémité libre de la partie de languette 6, est pourvue d'une patte 17 de verrouillage adaptée pour être arrachée ou sectionnée lors de la première utilisation.Furthermore, in order to ensure a sort of inviolability of the closure before use, the free end of the tongue part 6 is provided with a locking tab 17 adapted to be torn off or severed during the first use.
