Description

La présente invention a pour objet un dispositif de fermeture pour flacons, bouteilles ou récipients analogues, et elle concerne plus particulièrement un dispositif de fermeture qui assure une protection en nécessitant, pour son ouverture,une manipulation particulière.The present invention relates to a closure device for flasks, bottles or similar containers, and it relates more particularly to a closure device which provides protection by requiring, for its opening, a particular manipulation.

On sait que dans la maison, pour des raisons de sécurité, les jeunes enfants ne doivent pas avoir accès au contenu de certains récipients dont la manipulation ou l'ingestion pourrait entraîner des accidents graves et parfois mortels. Il en est ainsi en particulier des flacons contenant des médicaments et des bouteilles ou récipients renfermant divers produits de nettoyage et d'entretien. En dépit de la vigilance dont peuvent faire preuve les parents, il est parfois inévitable que de tels récipients se trouvent à un moment à la portée d'enfants qui, s'ils arrivent à les déboucher, peuvent alors être victimes d'intoxications ou d'accidents graves.We know that in the home, for safety reasons, young children should not have access to the contents of certain containers whose handling or ingestion could lead to serious and sometimes fatal accidents. This is particularly the case with bottles containing medicines and bottles or containers containing various cleaning and maintenance products. Despite the vigilance which the parents can exercise, it is sometimes inevitable that such containers are at some point within reach of children who, if they manage to uncork them, can then be victims of poisoning or d '' serious accidents.

Une protection, s'ajoutant au rangement des récipients hors de la portée des enfants, consiste à équiper ceux-ci d'un dispositif de fermeture qui, pour réaliser le débouchage, nécessite d'effectuer plusieurs opérations dans un ordre déterminé, ce qui élimine pratiquement la possibilité d'une ouverture intempestive due au hasard en cas de manipulation par un jeune enfant.A protection, in addition to the storage of the containers out of the reach of children, consists in equipping them with a closing device which, in order to unclog, requires carrying out several operations in a determined order, which eliminates practically the possibility of an untimely opening due to chance in case of manipulation by a young child.

La présente invention propose un tel dispositif de bouchage de protection, destiné à se visser sur le col du récipient à boucher, qui est de fabrication simple et peu coûteuse, d'une excellente efficacité de bouchage, qui ne peut pas être ouvert par une manipulation accidentelle en particulier s'il est manoeuvré par un jeune enfant, et qui est réutilisable sans rien perdre de ses qualités.The present invention provides such a protective closure device, intended to be screwed onto the neck of the closure container, which is simple and inexpensive to manufacture, with excellent sealing efficiency, which cannot be opened by manipulation. accidental in particular if it is operated by a young child, and which is reusable without losing anything of its qualities.

On connaît, par le document DE-A-3 041 230, un bouchon de protection qui comprend un capuchon intérieur se vissant sur col du récipient à boucher et un capuchon extérieur conçu pour se déplacer verticalement par rapport au capuchon intérieur en s'appuyant pour son guidage sur la partie externe du capuchon intérieur. La tête du capuchon extérieur présente sur sa face interne des crans qui, lorsque ce capuchon extérieur est enfoncé contre l'action de languettes élastiques, coopérent avec des crans du capuchon interne pour entraîner ce dernier en rotation et dévisser le bouchon. Comme le guidage vertical du capuchon extérieur est assuré par la face extérieure de la jupe du capuchon intérieur, il est nécessaire de réaliser ce dernier en une matière rigide pour ne pas risquer un blocage aléatoire du bouchon lors de son actionnement et cela présente un inconvénient majeur au niveau de l'étanchéité du bouchage. En effet la qualité de l'étanchéité obtenue est bien supérieure lorsque le capuchon intérieur est réalisé en une matière souple.Document DE-A-3 041 230 discloses a protective cap which comprises an inner cap which is screwed onto the neck of the corking container and an outer cap designed to move vertically relative to the inner cap while resting on it. its guide on the outer part of the inner cap. The head of the outer cap has notches on its inner face which, when this outer cap is pressed against the action of elastic tabs, cooperate with notches of the inner cap to drive the latter in rotation and unscrew the cap. As the vertical guide of the outer cap is provided by the outer face of the skirt of the inner cap, it is necessary to make the latter from a rigid material so as not to risk a random blocking of the cap when it is actuated and this has a major drawback at the sealing of the closure. Indeed, the quality of the seal obtained is much higher when the inner cap is made of a flexible material.

On connaît aussi, par le document FR-A-­2 116 536, une fermeture de protection comprenant un capuchon de bouchage qui se visse sur le col du récipient et un capuchon de recouvrement qui présente une possibilité de déplacement vertical limité en s'appuyant, pour son guidage, sur la face extérieure de la jupe du capuchon de bouchage. La limitation de ce déplacement est assurée dans un sens par l'engagement des extrémités retournées se faisant face de collerettes portées par les faces horizontales en regard des deux capuchons. La protection assurée par ce bouchon se situe au niveau du déchirage de la bague d'inviolabilité, et n'est pas assurée en cas de réutilisation du bouchon. En outre, comme dans le cas du document DE-A-3 041 230, le guidage vertical assuré par la partie extérieure du capuchon de bouchage interdit de réaliser ce dernier en une matière souple assurant une bonne étanchéité.Document FR-A-2 116 536 also discloses a protective closure comprising a plugging cap which is screwed onto the neck of the container and a covering cap which presents a possibility of limited vertical movement by resting, for its guidance, on the outside of the skirt of the stopper cap. The limitation of this movement is ensured in one direction by the engagement of the turned ends facing each other with collars carried by the horizontal faces opposite the two caps. The protection provided by this plug is located at the tearing of the tamper-evident ring, and is not ensured in the event of re-use of the plug. In addition, as in the case of document DE-A-3 041 230, the vertical guidance provided by the external part of the plugging cap prevents it from being made of a flexible material ensuring good sealing.

Selon l'invention le bouchon de protection, réalisé en matière plastique moulée, comprend une partie de bouchage se vissant sur le col du récipient et une partie d'actionnement qui est liée à ladite partie de bouchage par des moyens permettant par rapport à celle-ci une possibilité de déplacement vertical limité et guidé, des éléments saillants en regard étant portés par lesdites deux parties de bouchon afin de ne permettre un entraînement en rotation de ladite partie de bouchage par ladite partie d'actionnement que lorsqu'une pression verticale est appliquée à la partie d'actionnement pour provoquer un engagement mutuel desdits éléments saillants et il se caractérise d'une part en ce que la partie de bouchage est constituée en une matière souple et, d'autre part, en ce que le guidage verticale de la partie d'actionnement est assuré intérieurement à la partie de bouchage par coopération continue d'une collerette de la partie de bouchage avec les parois d'une cheminée présentée par la face inerne du dessus de la partie d'actionnement.According to the invention, the protective plug, made of molded plastic, comprises a plugging part which is screwed onto the neck of the container and an actuating part which is linked to said plugging part by means allowing, with respect to the latter. ci a possibility of limited and guided vertical displacement, facing projecting elements being carried by said two plug parts so as to allow a rotary drive of said plugging part by said actuating part only when vertical pressure is applied to the actuating part to cause mutual engagement of said projecting elements and it is characterized on the one hand in that the plugging part is made of a flexible material and, on the other hand, in that the vertical guidance of the actuating part is provided internally to the plugging part by continuous cooperation of a flange of the plugging part with the walls of a chimney presented by the f ace inerne above the actuating part.

On comprend alors que, avec le bouchon selon l'invention, on obtient une excellente étanchéité grâce à la réalisation de la partie de bouchage en une matière souple tout en évitant tout risque de blocage aléatoire du bouchon grâce au guidage intérieur continu du déplacement vertical de la partie d'actionnement.It will then be understood that, with the stopper according to the invention, an excellent seal is obtained thanks to the production of the stopper part in a flexible material while avoiding any risk of random blocking of the stopper thanks to the continuous internal guidance of the vertical displacement of the actuation part.

Avantageusement la partie de bouchage du bouchon selon l'invention est réalisée de façon que sa collerette de guidage, après mise en place du bouchon sur le récipient, se trouve disposée à l'intérieur du col de ce dernier en supprimant tout risque de basculement du récipient lors de l'actionnement du bouchon.Advantageously, the stoppering part of the stopper according to the invention is made so that its guide flange, after the stopper has been placed on the container, is placed inside the neck of the latter, eliminating any risk of tilting of the container when the cap is actuated.

Selon une forme de réalisation préférée, les éléments saillants sont constitués par des crans portés par une face de l'une des parties de bouchon (en particulier par la face inférieure de la partie d'actionnement) et par des rampes obliques portées par la face en regard de l'autre partie de bouchon.According to a preferred embodiment, the projecting elements consist of notches carried by one face of one of the plug parts (in particularly by the underside of the actuating part) and by oblique ramps carried by the opposite face of the other plug part.

On comprend donc que l'ouverture du bouchon, c'est-à-dire son dévissage, ne pourra être obtenue qu'en appliquant à la partie d'actionnement du bouchon, simultanément au mouvement de rotation dans le sens du dévissage, une poussée verticale. Si cette poussée verticale n'est pas appliquée, la coopération des crans et des rampes obliques, lors de la rotation de la partie d'actionnement, provoquera un écartement relatif des deux parties de bouchon empêchant l'engagement mutuel des crans et des rampes obliques et donc l'entraînement en rotation de la partie de bouchage.It is therefore understood that the opening of the plug, that is to say its unscrewing, can only be obtained by applying to the actuating part of the plug, simultaneously with the rotational movement in the direction of unscrewing, a thrust vertical. If this vertical thrust is not applied, the cooperation of the notches and oblique ramps, during the rotation of the actuating part, will cause a relative spacing of the two plug parts preventing mutual engagement of the notches and oblique ramps and therefore the rotational driving of the closure part.

Selon une caractéristique complémentaire importante, la partie de bouchage du bouchon de protection selon l'invention se poursuit à sa partie inférieure par une bague d'inviolabilité que lui est liée par des moyens déchirables (tels par exemple qu'une toile ou une liaison par points), de façon à mettre en évidence la première ouverture du bouchon.According to an important additional characteristic, the plugging part of the protective cap according to the invention continues at its lower part by a tamper-evident ring which is linked to it by tearable means (such as for example a canvas or a connection by points), so as to highlight the first opening of the cap.

Pour bien faire comprendre le bouchon selon l'invention, on en décrira ci-après, à titre d'exemple sans caractère limitatif, une forme d'exécution préférée en référence au dessin schématique annexé dans lequel :

  • la figure 1 est une vue en coupe verticale d'un bouchon selon l'invention représenté en position relevée de protection sur la partie de gauche de la figure et en position enfoncée permettant son ouverture sur la partie de droite ; et
  • la figure 2 est une vue en élévation du bouchon de la figure 1 en position enfoncée, la bague d'inviolabilité étant en place sur la partie de gauche de la figure et étant arrachée sur la partie de droite.
To make the plug according to the invention clear, a preferred embodiment will be described below, by way of example, with reference to the appended schematic drawing in which:
  • Figure 1 is a vertical sectional view of a plug according to the invention shown in the raised protective position on the left part of the figure and in the depressed position allowing its opening on the right part; and
  • Figure 2 is an elevational view of the cap of Figure 1 in the depressed position, the tamper-evident ring being in place on the left part of the figure and being torn off on the right part.

En référence au dessin le bouchon, réalisé en matière plastique moulée, est constitué en deux parties. Il comprend une partie d'obturation souple, par exemple en polyéthylène basse densité, avec un élément intérieur 1 destiné à s'engager dans la col de la bouteille et qui se prolonge vers l'extérieur par une jupe se vissant, dans l'exemple représenté, par un filet double sur un filet double correspondant du col 3 de la bouteille. La jupe 2 est reliée par une toile 4 à une bague d'inviolabilité 5 comportant des crans verticaux intérieurs 6 engagés dans d'autres crans verticaux 7 de la bague 8 du col 3 de la bouteille et se terminant par une languette d'ouverture 9. Sur sa face supérieure l'élément 1 présente une collerette 10 se terminant à son extrémité supérieure par un bourrelet 11.With reference to the drawing, the stopper, made of molded plastic, is made up of two parts. It comprises a flexible sealing part, for example made of low density polyethylene, with an internal element 1 intended to engage in the neck of the bottle and which extends outwards by a skirt which is screwed, in the example shown, by a double thread onto a corresponding double thread from the neck 3 of the bottle. The skirt 2 is connected by a canvas 4 to a tamper-evident ring 5 comprising internal vertical notches 6 engaged in other vertical notches 7 of the ring 8 of the neck 3 of the bottle and ending with an opening tongue 9 On its upper face, the element 1 has a collar 10 ending at its upper end with a bead 11.

La seconde partie du bouchon, qui est une partie d'actionnement réalisée par exemple en polypropylène, comprend un capot extérieur 12 constitué d'une partie supérieure plane se poursuivant par une jupe 13 qui présente un diamètre intérieur légèrement supérieur au diamètre extérieur de la jupe 2 de façon à ne pas engager cette dernière. Cette jupe 13 comporte extérieurement des crans 14 permettant une bonne saisie par l'utilisateur. Sur sa face intérieure la partie plane du capot 12 présente une gorge circulaire 15 en forme de cheminée dans laquelle s'engage avec un léger jeu la collerette 10, la gorge 15 comportant à son extrémité inférieure un rebord 16 dirigé vers l'intérieur qui autorise le déplacement de la collerette 10 à l'intérieur de la gorge 15 tout en interdisant la sortie de la collerette 10 par venue en butée du bourrelet 11 contre le rebord 16 de la gorge 15. Le guidage du déplacement vertical de la seconde partie du bouchon est assurée par la coopération continue de la collerette 10 avec les parois de la gorge 15. Comme on le voit sur la figure 1, la collerette 10 est disposée tout entière à l'intérieur du col 3 du récipient ce qui fournit une excellente assise lors de l'actionnement du bouchon.The second part of the plug, which is an actuating part made for example of polypropylene, comprises an outer cover 12 consisting of a flat upper part continuing with a skirt 13 which has an inside diameter slightly greater than the outside diameter of the skirt 2 so as not to engage the latter. This skirt 13 externally has notches 14 allowing good grip by the user. On its inner face the flat part of the cover 12 has a circular groove 15 in the form of a chimney in which the flange 10 engages with a slight clearance, the groove 15 having at its lower end a flange 16 directed inwards which allows the movement of the flange 10 inside the groove 15 while preventing the exit of the flange 10 by abutment of the bead 11 against the flange 16 of the groove 15. Guiding the vertical movement of the second part of the stopper is ensured by the continuous cooperation of the flange 10 with the walls of the groove 15. As can be seen in FIG. 1, the flange 10 is entirely arranged inside the neck 3 of the container, which provides excellent seating during actuation of the plug.

Sur sa face intérieure la partie plane du capot 12 présente également des crans 17 qui sont disposée en regard de rampes obliques 18 portées en couronne par la partie intérieure 1 du bouchon.On its inner face the flat part of the cover 12 also has notches 17 which are arranged opposite oblique ramps 18 carried in a crown by the internal part 1 of the plug.

Le mode d'utilisation du bouchon est le suivant. Pour une première ouverture, on effectue d'abord une traction manuelle sur la languette 9 pour déchirer la toile 4 et arracher la bague d'inviolabilité 5. On exerce ensuite une pression sur le capot 12 selon la flèche F de la figure 1, de façon à engager les crans 17 de celui-ci entre les rampes 18 de la partie de bouchon 1, puis simultanément on entraine en rotation le capot 12 dans le sens du dévissage ce qui entraine le dévissage de la partie intérieure 1 en raison de l'engagement mutuel des crans 17,18.The method of using the cap is as follows. For a first opening, we first perform manual traction on the tongue 9 to tear the canvas 4 and tear off the tamper-evident ring 5. Pressure is then exerted on the cover 12 according to arrow F in FIG. 1, so as to engage the notches 17 thereof between the ramps 18 of the plug part 1, then simultaneously driving the cover 12 in the direction of unscrewing which causes the unscrewing of the inner part 1 due to the mutual engagement of the notches 17,18.

Si l'effort axial dans la direction de la flèche F est inexistant ou faible (cas d'actionnement par un enfant), l'entrainement en rotation du capot 12 provoque alors le soulèvement de celui-ci par rapport à la partie 1 (par passage des crans 17 sur les rampes obliques 18) sans entrainer en rotation la partie intérieure 1 et donc sans assurer le dévissage du bouchon.If the axial force in the direction of the arrow F is nonexistent or weak (in the case of actuation by a child), the rotational drive of the cover 12 then causes it to be raised relative to the part 1 (by passage of the notches 17 on the oblique ramps 18) without causing the inner part 1 to rotate and therefore without unscrewing the plug.

Le rebouchage s'effectue par vissage du capot 12, en effectuant une faible pression axiale dans la direction de la flèche F.The filling is carried out by screwing the cover 12, by applying a low axial pressure in the direction of the arrow F.

Le processus d'ouverture est avantageusement explicité par un dessin qui est gravé sur le dessus du bouchon mais qui n'a pas été représenté sur les figures de la présente demande de brevet.The opening process is advantageously explained by a design which is engraved on the top of the stopper but which has not been shown in the figures of the present patent application.

On comprendra que la description ci-dessus a été donnée à simple titre d'exemple, sans caractère limitatif, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de l'invention définie par les revendications annexées. En particulier, on a décrit la bande d'inviolabilité 5 comme étant reliée à la jupe 3 de la partie intérieure du bouchon par une toile 4, mais celle-ci pourrait être remplacée par tout autre système de liaison déchirable approprié. De même on a représenté un filet double pour réaliser le vissage de la partie 1 du bouchon sur le col de la bouteille, mais on comprendra que ce filet pourrait être simple.It will be understood that the above description has been given by way of example, without limitation, and that additions or constructive modifications could be made without departing from the scope of the invention defined by the appended claims. In particular, the tamper-evident band 5 has been described as being connected to the skirt 3 of the inner part of the stopper by a fabric 4, but this could be replaced by any other suitable tear-away connection system. Similarly, a double thread has been shown for screwing part 1 of the stopper onto the neck of the bottle, but it will be understood that this thread could be simple.
