Description

La présente invention a pour objet un dispositif de bouchage de sécurité à usage unique.The present invention relates to a disposable safety closure device.

Certains produits dangereux actuellement sur le marché, tels que l'eau de javel sont conditionnés dans des doses qui, après ouverture, doivent être utilisées en une seule fois. Les bouchages utilisés sont de type encliqueté ou soudé par ultra-sons mais aucun d'entre eux n'est prévu pour résister à l'ouverture par un jeune enfant. En revanche, ces dispositifs de bouchage évitent toute possibilité de rebouchage du contenant après la première ouverture.Certain dangerous products currently on the market, such as bleach, are packaged in doses which, after opening, must be used all at once. The closures used are of the snap-on or ultrasonic welded type, but none of them is designed to resist opening by a young child. However, these closure devices avoid any possibility of recapping the container after the first opening.

D'autres dispositifs de bouchage sont de type "child proof', c'est-à-dire possèdent une structure telle que l'ouverture du récipient équipé ne puisse être réalisée que par coordination de plusieurs mouvements.Other closure devices are of the "child proof" type, that is to say have a structure such that the opening of the fitted container can only be achieved by coordination of several movements.

Le but de l'invention est de fournir un dispositif de bouchage de sécurité, c'est-à-dire un dispositif ne pouvant être ouvert facilement par un jeune enfant, ou ouvert de façon accidentelle, et qui soit à usage unique, c'est-à-dire quine puisse plus assurer la fermeture du contenant qu'il équipe après première ouverture.The object of the invention is to provide a safety closure device, that is to say a device which cannot be opened easily by a young child, or opened accidentally, and which is for single use, it that is to say, it can no longer ensure the closure of the container it equips after first opening.

A cet effet, le dispositif qu'elle concerne comprend en combinaison :

  • - un bouchon équipé de moyens de fixation irréversible sur le col d'un récipient, comportant au-delà de ce col une partie tubulaire dont l'extrémité libre est obturée par un opercule, est reliée à la partie fixée sur le col du récipient par une zone annulaire comportant un amincissement de matière, et est équipée d'une languette de déchirage faisant saillie du côté opposé au récipient, la zone de la partie tubulaire solidaire du récipient comportant au-delà du bord du col, une lèvre fais- sant saillie radialement vers l'extérieur dans laquelle sont ménagées des découpes de forme déterminée et,
  • - une cape de sécurité comportant une jupe circulaire entourant la partie tubulaire du bouchon et recouvrant la languette de déchirage, dont l'extrémité située du côté du col du récipient comporte un rebord tourné radialement vers l'extérieur, prolongé par une jupe cylindrique destinée à recouvrir la lèvre du bouchon sur une hauteur au moins égale à l'épaisseur de cette lèvre, et dont l'extrémité libre comprend au moins un retour vers l'intérieur, le nombre et la forme de ces retours correspondant à ceux des découpes ménagées dans la lèvre du bouchon.
To this end, the device which it concerns comprises in combination:
  • - A stopper fitted with irreversible fixing means on the neck of a container, comprising beyond this neck a tubular part, the free end of which is closed by a cover, is connected to the part fixed to the neck of the container by an annular zone comprising a thinning of material, and is equipped with a tear-off tab projecting from the side opposite to the container, the zone of the tubular part integral with the container comprising beyond the edge of the neck, a projecting lip radially outward in which are cutouts of determined shape and,
  • a safety cap comprising a circular skirt surrounding the tubular part of the stopper and covering the tear-off tab, the end of which located on the side of the neck of the container has a rim turned radially outwards, extended by a cylindrical skirt intended for cover the lip of the plug over a height at least equal to the thickness of this lip, and the free end of which includes at least one return towards the inside, the number and the shape of these returns corresponding to those of the cutouts provided in the lip of the cap.

La cape recouvrant le bouchon assure la sécurité de la fermeture du récipient, du fait que cette cape ne peut être retirée du bouchon qu'après avoir réalisé son positionnement angulaire de façon précise, de telle sorte que les retours qu'elle comporte se trouvent dans l'alignement des ouvertures ménagées dans la lèvre du bouchon. Pour sa part, le bouchon ne peut servir à la fermeture du récipient, après une première ouverture, puisque cette première ouverture se traduit par la désolidarisation de la partie du bouchon comportant l'opercule de fermeture et de la partie du bouchon montée sur le col du récipient.The cap covering the cap ensures the safety of the closure of the container, since this cap can only be removed from the cap after having achieved its angular positioning in a precise manner, so that the returns which it comprises are in the alignment of the openings in the lip of the stopper. For its part, the stopper cannot be used to close the container, after a first opening, since this first opening results in the separation of the part of the stopper comprising the closure cap and the part of the stopper mounted on the neck. of the container.

Conformément à une autre caractéristique de l'invention, la languette de déchirage s'étend dans le prolongement de la partie tubulaire, sur une partie de la périphérie de celle-ci.According to another characteristic of the invention, the tear-off tongue extends in the extension of the tubular part, over a part of the periphery thereof.

Avantageusement, la cape de sécurité comprend, à l'extrémité libre de la jupe circulaire, un retour vers l'intérieurqui, recouvrant le bord supérieur de la languette, comporte une partie centrale ouverte.Advantageously, the safety cap comprises, at the free end of the circular skirt, an inward return which, covering the upper edge of the tongue, has an open central part.

Cette caractéristique est avantageuse car la cape, tout en assurant une excellente protection de la languette de déchirage du bouchon, laisse, par sa partie centrale ouverte, la vision directe de la partie centrale du bouchon. Cela permet à un consommateur souhaitant acheter le récipient équipé de ce dispositif, de vérifier instantanément et visuellement que l'opercule de bouchage n'a pas été détérioré.This characteristic is advantageous because the cap, while ensuring excellent protection of the tear-off tab of the cap, leaves, by its open central part, direct vision of the central part of the cap. This allows a consumer wishing to buy the container equipped with this device, to instantly and visually check that the closure cap has not been damaged.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce dispositif de bouchage.

  • Figure 1 en est une vue en perspective ;
  • Figure 2 est une vue en perspective avec coupe par un plan médian longitudinal du bouchon ;
  • Figure 3 est une vue en coupe longitudinale et à échelle agrandie du dispositif de bouchage en position montée sur le col d'un récipient ;
  • Figures 4 et 5 sont deux vues en coupe longitudinale du bouchon respectivement avant ouverture et après ouverture ;
  • Figure 6 est une vue en coupe du bouchon selon la ligne VI-VI de figure 3.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of this closure device.
  • Figure 1 is a perspective view;
  • Figure 2 is a perspective view with section through a longitudinal median plane of the plug;
  • Figure 3 is a longitudinal sectional view on an enlarged scale of the closure device in the mounted position on the neck of a container;
  • Figures 4 and 5 are two views in longitudinal section of the plug respectively before opening and after opening;
  • Figure 6 is a sectional view of the plug along line VI-VI of Figure 3.

Le dispositif de bouchage, selon l'invention, désigné par la référence générale 2 à la figure 1, comprend un bouchon 3 et une cape de sécurité 4 destinés à venir se fixer par-dessus le bouchon.The closure device according to the invention, designated by the general reference 2 in FIG. 1, comprises a stopper 3 and a safety cap 4 intended to be fixed over the stopper.

Le bouchon 3 comporte un profil emboîtant creux 5 destiné à venir coiffer le bord supérieur 6 du col 7 d'un récipient. L'accrochage de l'emboîtement creux 5 sur le col du récipient est réalisé par l'intermédiaire d'épaulement 8 et de bossage 9 complémentaires, ménagés respectivement sur le col 7 et sur le bouchon. Ce montage est tel qu'il soit irréversible. Afin d'éviter que l'on puisse désolidariser le bouchon du col du récipient, par exemple à l'aide d'un outil, un épaulement 10 que comporte le col 7 vient affleurer au niveau de l'extrémité inférieure du bouchon. Au-dessus du bord 6 du col du récipient, le bouchon se prolonge vers l'extérieur par une partie tubulaire 12, dont l'extrémité libre est obturée par un opercule 13. La partie tubulaire 12 comporte une zone amincie de matière 14, susceptible d'être déchirée. Afin de permettre ce déchirage, il est prévu une languette 15 qui fait saillie du côté opposé au col du récipient 7, cette languette 15 s'étendant dans le prolongement de la partie tubulaire, sur une partie de la périphérie de celle-ci. Entre la zone amincie 14 et l'emboîtement 5, la partie tubulaire 15 comporte une lèvre 16 faisant saillie radialement vers l'extérieur, dans laquelle sont ménagées des découpes 17 de forme déterminée. Comme montré au dessin et notamment à la figure 6, la forme de ces découpes n'est pas régulière, et leur répartition angulaire n'est également pas régulière.The plug 3 comprises a hollow interlocking profile 5 intended to come over the upper edge 6 of the neck 7 of a container. The hooking of the hollow socket 5 on the neck of the container is carried out by means of shoulder 8 and complementary boss 9, formed respectively on the neck 7 and on the cap. This arrangement is such that it is irreversible. In order to prevent the cap from being able to be detached from the neck of the container, for example using a tool, a shoulder 10 which the neck 7 includes is flush with the lower end of the cap. Above the edge 6 of the container neck, the stopper is extended outwards by a tubular part 12, the free end of which is closed by a cover 13. The tubular part 12 comprises a thinned zone of material 14, capable of to be torn apart. In order to allow this tearing, a tongue 15 is provided which projects from the side opposite the neck of the container 7, this tongue 15 extending in the extension of the tubular part, over a part of the periphery thereof. Between the thinned zone 14 and the socket 5, the tubular part 15 comprises a lip 16 projecting radially outwards, in which are cutouts 17 of determined shape. As shown in the drawing and in particular in Figure 6, the shape of these cutouts is not regular, and their angular distribution is also not regular.

La cape de sécurité 4 comporte, pour sa part, une jupe circulaire 18 entourant la partie tubulaire 12 du bouchon et recouvrant la languette de déchirage 15. A cet effet, la jupe 18 comporte un retour 19 vers l'intérieur qui recouvre la languette, le bord intérieur de ce retour délimitant une ouverture centrale 20. L'extrémité de la jupe 18 située du côté du col du récipient comporte un rebord 22 tourné radialementvers l'extérieur, est destiné à venir prendre appui sur la lèvre 16 du bouchon. Ce rebord 22 est prolongé du côté du col du récipient par une partie 23 en forme de jupe cylindrique d'une hauteur au moins égale à l'épaisseur de la lèvre 16. L'extrémité libre de la jupe 23 comporte au moins un retour 24 vers l'intérieur, le nombre et la forme des retours 24 correspondant à ceux des découpes 17 ménagées dans la lèvre 16 du bouchon. Ces retours 24 sont susceptibles de passer sous la lèvre 16 pour constituer des organes d'accrochage de la cape de sécurité vis-à-vis du bouchon. Il ressort de cette structure qu'en position de fermeture du récipient, la cape est accrochée sur le bouchon et occupe une position angulaire vis-à-vis de celui-ci. Pour réaliser l'ouverture du récipient, il convient donc d'amener la cape 4 dans une position angulaire telle que les retours 24 qu'elle comporte soient disposés en regard des découpes 17 de la lèvre 16. Ce positionnement angulaire peut être facilité par mise en coïncidence de repères, ménagés respectivement sur le bouchon et sur la cape. Une fois cette mise en coïncidence réalisée, la cape 4 est retirée par déplacement axial. Il peut alors être procédé à l'ouverture du bouchon en exerçant une traction sur la languette 15, assurant la désolidarisation de celle-ci et des éléments qui en sont solidaires tels que l'opercule 13, vis-à-vis de la partie du bouchon montée sur le col du récipient, par déchirure de la zone amincie 14. Les figures 4 et 5 représentent le bouchon 3 respectivement avant ouverture, et après ouverture. Il ressort de cette structure qu'après ouverture le récipient ne peut plus être fermé.The safety cap 4 comprises, for its part, a circular skirt 18 surrounding the tubular part 12 of the stopper and covering the tear-off tab 15. For this purpose, the skirt 18 has a return 19 towards the inside which covers the tab, the inner edge of this return defining a central opening 20. The end of the skirt 18 located on the side of the container neck has a flange 22 turned radially outwards, is intended to come to bear on the lip 16 of the plug. This rim 22 is extended on the side of the container neck by a part 23 in the form of a cylindrical skirt with a height at least equal to the thickness of the lip 16. The free end of the skirt 23 has at least one return 24 inward, the number and shape of the returns 24 corresponding to those of the cutouts 17 formed in the lip 16 of the plug. These returns 24 are capable of passing under the lip 16 to constitute fastening members of the safety cap vis-à-vis the cap. It emerges from this structure that in the closed position of the container, the cap is hung on the stopper and occupies an angular position with respect thereto. To achieve the opening of the container, it is therefore necessary to bring the cap 4 in an angular position such that the returns 24 which it comprises are arranged opposite the cutouts 17 of the lip 16. This angular positioning can be facilitated by placing coinciding with marks, formed respectively on the cap and on the cap. Once this coincidence has been achieved, the cap 4 is removed by axial displacement. The plug can then be opened by exerting traction on the tongue 15, ensuring the separation of the latter and of the elements which are integral therewith such as the cover 13, with respect to the part of the cap mounted on the neck of the container, by tearing the thinned zone 14. FIGS. 4 and 5 show the cap 3 respectively before opening, and after opening. It emerges from this structure that after opening the container can no longer be closed.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un dispositif de bouchage à usage unique, et de sécurité puisque sa structure évite toute ouverture accidentelle.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a disposable closure device, and safety since its structure avoids any accidental opening.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce dispositif de bouchage décrit ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation.It goes without saying that the invention is not limited to the sole embodiment of this closure device described above by way of example, on the contrary, it embraces all of the variant embodiments thereof.

C'est ainsi, notamment, que la forme et le nombre des ouvertures 17 ménagées dans la lèvre 16 et des retours 24 solidaires de la cape 4, pourraient être différents, ou encore que l'extrémité libre de la cape 4 pourrait ne pas comporter une ouverture 20 mais être obturée par un voile de matière, sans que l'on sorte pour autant du cadre de l'invention.Thus, in particular, that the shape and the number of openings 17 formed in the lip 16 and the returns 24 integral with the cap 4, could be different, or even that the free end of the cap 4 could not include an opening 20 but be closed by a veil of material, without departing from the scope of the invention.
