Description

La présente invention concerne un bouchon destructible à usage unique réalisé en une matière thermoplastique qui, par son extrémité inférieure, est fixée à demeure et de façon étanche sur le bord libre d'un goulot d'une bouteille et qui comprend une obturation frontale et une paroi latérale dite jupe dont l'extrémité supérieure est raccordée à ladite obturation.The present invention relates to a single-use destructible stopper made of a thermoplastic material which, by its lower end, is fixed permanently and sealingly to the free edge of a neck of a bottle and which comprises a front closure and a side wall known as a skirt, the upper end of which is connected to said closure.

Un bouchon de ce type est connu, par exemple par le brevet GB 931 695. Dans ce cas, la jupe est de forme conique dont la pointe est terminée par un petit houchon qui, après avoir été découpé, libère un passage étroit permettant la distribution goutte à goutte d'un liquide. Ce bouchon connu ne permet pas l'écoulement rapide du liquide contenu dans le récipient et, en plus, retient toujours une quantité plus ou moins grande de liquide dans sa partie conique, ce qui peut être dangereux lorsque le liquide est toxique.A plug of this type is known, for example from patent GB 931 695. In this case, the skirt is conical in shape, the tip of which is terminated by a small hook which, after being cut, frees a narrow passage allowing distribution. drip of a liquid. This known stopper does not allow the rapid flow of the liquid contained in the container and, in addition, always retains a greater or lesser quantity of liquid in its conical part, which can be dangerous when the liquid is toxic.

D'autres bouchons, par exemple, connus par le brevet GB 869 398 et le brevet FR 2.115.833 sont réutilisables et destinés au rebouchage du récipient, ce qui est un inconvénient lorsque ce récipient contient une dose unitaire de produit, par exemple toxique ou curatif, qui doit être utilisée en une seule fois et qu'en vue d'inciter l'utilisateur à ne pas conserver une partie de la dose unitaire, ce récipient ne doit pas pouvoir être rebouché avec le bouchon d'origine. Par ailleurs, les bouchons connus de ce typene se prêtent pas à un découpage facile et automatique lorsque l'outil de coupe est logé dans le goulot d'un autre récipient.Other stoppers, for example, known from patent GB 869 398 and patent FR 2 115 833 are reusable and intended for recapping the container, which is a drawback when this container contains a unit dose of product, for example toxic or curative, which must be used all at once and in order to encourage the user not to keep part of the unit dose, this container must not be able to be refilled with the original cap. Furthermore, the known plugs of this type do not lend themselves to easy and automatic cutting when the cutting tool is housed in the neck of another container.

La presente invention supprime ces inconvenients et a pour but de proposer un bouchon du type initialement mentionné et offrant les possibilités d'une manipulation unique facile et sans danger.The present invention eliminates these drawbacks and aims to provide a plug of the type initially mentioned and offering the possibilities of easy and safe single handling.

Ce but est atteint grâce à un bouchon destructible conforme à la revendication 1.This object is achieved by a destructible plug according to claim 1.

D'autres particularites de l'invention sont exposées dans les revendications 2 à 11.Other features of the invention are set out in claims 2 to 11.

L'invention concerne aussi un récipient tel que flacon, bouteille, tube, pot, etc. muni d'un bouchon conforme aux caractéristiques susmentionnées.The invention also relates to a container such as a bottle, bottle, tube, pot, etc. fitted with a plug conforming to the above characteristics.

Tel que représente sur le dessin annexe, le bouchon destructible 1, de préference en matièrethermoplastique est fixé à demeure sur le bord 2a d'un goulot 2 d'un récipient également en matière thermoplastique non représenté. Le bouchon destructible 1 presente, tout au moins à sa partie inférieure, une section transversale similaire a celle du goulot 2, par exemple circulaire, ovale, ou polygonale et comprend, à son extremité supérieure, une paroi d'obturation 3 qui peut être légèrement bombée vers l'extérieur (fig. 2) ou vers l'intérieur (fig. 5) et qui est prolongée vers le bas (c'est-à-dire vers le récipient) par une jupe latérale 4 dont l'extrémité inférieure 4a est conformée en un bourrelet munie d'une rainure ou gorge annulaire coaxiale 4b dont les flancs latéraux 4c et 4d coiffent le bord 2a du goulot 2. Le bouchon 1 étant réalisé en une matière thermoplastique, la fixation étanchede sa jupe 4 sur le bord 2a du goulot 2 peut se faire par collage ou par soudure à chaud par exemple à ultrasons.As shown in the accompanying drawing, the destructible plug 1, preferably made of thermoplastic material, is permanently fixed to the edge 2a of a neck 2 of a container also made of thermoplastic material, not shown. The destructible plug 1 has, at least at its lower part, a cross section similar to that of the neck 2, for example circular, oval, or polygonal and comprises, at its upper end, a closure wall 3 which may be slightly curved outwards (fig. 2) or inwards (fig. 5) and which is extended downwards (that is to say towards the container) by a side skirt 4 whose lower end 4a is shaped as a bead provided with a coaxial annular groove or groove 4b, the lateral flanks 4c and 4d covering the edge 2a of the neck 2. The plug 1 being made of a thermoplastic material, the waterproof fixing of its skirt 4 on the edge 2a the neck 2 can be made by gluing or by hot welding, for example ultrasonic.

Le flanc latéral intérieur 4d de l'extrémité inférieure de la jupe 4 penetre sur une faible longueur dans le goulot 2 et est applique contre la face interieure dudit goulot 2. Ce flanc latéral interieur 4d se trouve par exemple dans le prolongement de la partie de jupe 4e située au-dessous du bourrelet 4a et éu bord de goulot 2a (fig 1 à3).The internal lateral flank 4d of the lower end of the skirt 4 penetrates a short length into the neck 2 and is applied against the interior face of said neck 2. This internal lateral flank 4d is for example in the extension of the part of 4th skirt located below the bead 4a and at the edge of the neck 2a (fig 1 to 3).

A partir de la face exterieurc de la jupe laterale 4 sont ménagées dans celle-ci deux gorges annulaires 5, 6, paralleles entre-elles et perpendiculaires à l'axe 7 du goulot 2. Ces gorges annulaires 5,6 se trouvent en face de zones annulaires d'affaiblissement 8, 9 dont l'épaisseur est plus faible que l'epaisseur normale de la paroi de la jupe laterale 4 et qui peuvent être déchirées. Les gorges annulaires 5,6 et les zones d'affaiblissement 8,9 delimitent dans la jupe 4 une bande annulaire de déchirement 10 qui, par l'intermédiaire d'une pièce d'ecartemenf radial 11, est reliée à une languette de prehension 12 s'etendant, sur une courte distance, parallélément à la bande 10. Comme on peut le voir sur la figure 3, le bande de déchirement 10 présente au voisinage immédiat de le pièce d'écartement 11, dans sa partie recouverte par la languette de préhension 12, un amincissement 13 facilitant le début de l'arrachement de la partie de bande solidaire de la pièce d'ecartement 11. Bien entendu, le bouchon 1 étant réalisé en une matière thermoplastique et venu de moulage, tous les éléments constitutifs dudit bouchon 1 sont d'une seule pièce. L'épaisseur de la jupe 4 et la largeur ou haueteur axiale de la bande de dechirement 10 sont telles que la résistance à la traction de ladite bande 10 soit suffisante pour assurer le déchirement de la jupe 4 aux endroits des zonesd'affaiblissement 8,9, c'est-à-dire des gorges 5,6 et pour empêcher à la fois la rupture de ladite bande 10. Pour éviter que la partie supérieure 4e de la jupe 4, partie 4e solidaire de la paroi frontale d'obturation 3, après arrachement de la bande 10 ne puisse servir de bouchon, il est avantageux de prévoir la zone d'affaiblissement supérieure 8 au voisinage immédiat du bord de ladite paroi d'obturation 3From the outer face of the side skirt 4 are formed therein two annular grooves 5, 6, mutually parallel and perpendicular to the axis 7 of the neck 2. These annular grooves 5,6 are located opposite annular zones of weakness 8, 9 whose thickness is less than the normal thickness of the wall of the side skirt 4 and which can be torn. The annular grooves 5,6 and the weakening zones 8,9 delimit in the skirt 4 an annular tear strip 10 which, by means of a radial spacer 11, is connected to a gripping tongue 12 extending, over a short distance, parallel to the strip 10. As can be seen in FIG. 3, the tear strip 10 has in the immediate vicinity of the spacer 11, its part covered by the tongue of gripping 12, a thinning 13 facilitating the start of the tearing off of the strip part integral with the spacer 11. Of course, the plug 1 being made of a thermoplastic material and molded, all the constituent elements of said plug 1 are in one piece. The thickness of the skirt 4 and the width or axial height of the tear strip 10 are such that the tensile strength of said strip 10 is sufficient to ensure the tear of the skirt 4 at the locations of the weakening zones 8.9 , that is to say grooves 5,6 and to prevent both the rupture of said strip 10. To prevent the upper part 4e of the skirt 4, part 4 secured to the front closure wall 3, after tearing of the strip 10 cannot serve as a plug, it is advantageous to provide the upper weakening zone 8 in the immediate vicinity of the edge of said closure wall 3

Grâce à l'invention, l'ouverture du récipient non représenté est extrêmement simple et sans danger et doit se faire par la destruction du bouchon 1. Il suffit de tirer sur la languette de préhension 13 de façon à la faire tourner autour du goulot 2 à partir de son extrémité libre en direction de la pièce d'écartement 11. On constatera que la bande de déchirement 10 se séparera completement de la partie inférieure 4a de la jupe 4, partie inférieure 4a comprenant le bourrelet 4c et fixée à demeure sur le goulot 2, et que sur une faible longueur, elle restera attachée à la partie supérieure 4e de la jupe 4 ou à la paroi d'obturation 3, ce qui évite tout contact des doigts avec cette dernière.Thanks to the invention, the opening of the container, not shown, is extremely simple and harmless and must be done by destroying the plug 1. It suffices to pull on the gripping tab 13 so as to rotate it around the neck 2. from its free end in the direction of the spacer 11. It will be seen that the tear strip 10 will completely separate from the lower part 4a of the skirt 4, lower part 4a comprising the bead 4c and permanently fixed to the neck 2, and that over a short length, it will remain attached to the upper part 4 of the skirt 4 or to the closure wall 3, which avoids any contact of the fingers with the latter.

Le mode de réalisation du bouchonl représenté sur les figures 4 et 5 se distingue de celui représenté sur les figures 1 à 3 du fait que seule la partie inférieure 4a de la jupe 4, partie 4a engagée sur une faible longueur dans le goulot 2 d'un récipient non représenté tel qu'un flacon, présente la forme d'un cylindre à section transversale circulaire tandis que la partie intermédiaire 4f et la partie supérieure 4e de la jupe, bien que s'inscrivant dans un cylindre situé dans le prolongement de la partie cylindrique inférieure 4a de la jupe 4, comporte, du côté diamétralement opposé à la languette 12, un méplat tical 14 qui, vu en plan, est une sécante au cercle résultant de la projection en plan de la jupe cylindrique 4 du bouchon 1. La largeur de ce méplat 14 est relativement faible et ne s'étend pas au-delà d'un angle a d'une cinquantaine de degrés.The embodiment of the plug shown in Figures 4 and 5 differs from that shown in Figures 1 to 3 in that only the lower part 4a of the skirt 4, part 4a engaged over a short length in the neck 2 of a container, not shown, such as a bottle, has the shape of a cylinder with a circular cross-section while the intermediate part 4f and the upper part 4e of the skirt, although being part of a cylinder situated in the extension of the lower cylindrical part 4a of the skirt 4, comprises, on the side diametrically opposite the tongue 12, a tical flat 14 which, seen in plan, is secant to the circle resulting from the planar projection of the cylindrical skirt 4 of the plug 1. The width of this flat 14 is relatively small and does not extend beyond an angle a of about fifty degrees.

La jupe 4 comprend entre son extrémité cylindrique inférieure 4a pénétrant dans le goulot 2 d'un recipient non représenté en matière thermoplastique, et sa partie intermédiaire 4f une bride transversale annulaire 15 qui sert à la fixation du bouchon 1 dans un logement annulaire 16 prévu à l'extrémité supérieure du goulot 2. Ce logement annulaire 16 est délimité par une paroi cylindrique verticale 17 qui constitue le bord 2a, élargi par rapport au reste du goulot 2, et qui est de faible hauteur, notamment inférieur à la hauteur de la bride 15,et qui est suivie, en bas, par un épaulement intérieur 18 se raccordant à l'intérieur, sur la partie rétrécie du goulot 2, partie rétrécie recevant l'extrémité inférieure cylindrique 4a de la jupe 4. Avantageusement, la face inférieure de la bride 15 est munie d'une nervure de soudure 19de section transversale triangulaire. Comme ceci ressort des figures 4 et 5, la paroi du méplat 14 comprend une face extérieure verticale plane qui est située à l'intérieur du pourtour général cylindrique de la jupe 4 et une facs intérieure qui fait saillie vers la chambre 20 délimitée par le bouchon 1. La partie intermédiaire 4f de la jupe 4, qui présente une forme générale cylindrique, à l'exception du méplat 14 comporte une gorge horizontale d'affaiblissement 21 qui sert au guidage d'un outil de coupe et qui s'étend sur toute la partie du pourtour cylindrique de la jupe 4 et s'arrête au niveau du méplat 14.The skirt 4 comprises between its lower cylindrical end 4a penetrating into the neck 2 of a container not shown in thermoplastic material, and its intermediate part 4f an annular transverse flange 15 which serves for fixing the plug 1 in an annular housing 16 provided for the upper end of the neck 2. This annular housing 16 is delimited by a vertical cylindrical wall 17 which constitutes the edge 2a, widened with respect to the rest of the neck 2, and which is of low height, in particular less than the height of the flange 15, and which is followed, below, by an internal shoulder 18 connecting to the interior, on the narrowed part of the neck 2, narrowed part receiving the cylindrical lower end 4a of the skirt 4. Advantageously, the lower face of the flange 15 is provided with a welding rib 19 of triangular cross section. As can be seen from FIGS. 4 and 5, the wall of the flat part 14 comprises a flat vertical outer face which is situated inside the general cylindrical periphery of the skirt 4 and an inner facet which projects towards the chamber 20 delimited by the plug. 1. The intermediate part 4f of the skirt 4, which has a generally cylindrical shape, with the exception of the flat 14 has a horizontal weakening groove 21 which is used to guide a cutting tool and which extends over any the part of the cylindrical periphery of the skirt 4 and stops at the level of the flat 14.

La partie supérieure 4a de la jupe est séparée de la partie intermédiaire 4f par un épaulement horizontal 22 qui se termine par une paroi verticale plane 23 parallele au méplat 14 et qui coupe le rayon perpendiculaire de la partie cylindrique de la jupe 4 environ à mi-distance entre l'axe 7 et la périphérie de ladite partie cylindrique. Grâce à cette conception, on peut donner à la languette de préhension 12 la forme d'un arc de cercle situé à l'intérieur du pourtour cylindrique de la jupe 4 et se raccordant directement, c'est-à-dire sans pièce d'écartement, à la bande de déchirement 10. L'angle 5 inclu par la languette de préhension 12 en arc de cercle et la paroi verticale plane 23 est de l'ordre de 90° à 110 degrés. A son extrémité frontale, la languette de préhension 12 peut être reliée à la jupe 4 par un voile 24 extra-mince facilement déchirable et, à son autre extrémité, la languette de préhension 12 se raccorde directement à la bande de déchirement 10 prévue à la partie supérieure 4e de la jupe 4 sur tout le pourtour de celle-ci et délimitée, en haut et en bas, par les deux gorges annulaires horizontales 5, 6 et les zones annulaires d'affaiblissement correspondantes 8, 9.The upper part 4a of the skirt is separated from the intermediate part 4f by a horizontal shoulder 22 which ends in a flat vertical wall 23 parallel to the flat 14 and which intersects the perpendicular radius of the cylindrical part of the skirt 4 approximately halfway distance between axis 7 and the periphery of said cylindrical part. Thanks to this design, it is possible to give the gripping tongue 12 the shape of an arc of a circle situated inside the cylindrical periphery of the skirt 4 and connecting directly, that is to say without piece of spacing, to the tear strip 10. The angle 5 included by the gripping tab 12 in an arc of a circle and the flat vertical wall 23 is of the order of 90 ° to 110 degrees. At its front end, the gripping tab 12 can be connected to the skirt 4 by an extra-thin veil 24 which can easily be torn off and, at its other end, the gripping tab 12 is connected directly to the tearing strip 10 provided at the upper part 4e of the skirt 4 over the entire periphery thereof and bounded, at the top and at the bottom, by the two horizontal annular grooves 5, 6 and the corresponding annular weakening zones 8, 9.

Il est à noter que du fait que la languette de préhension 12 est située à l'intérieur du pourtour cylindrique de la jupe 4, celle-ci ne peut être arrachée intempestivement avec la bande de déchirement 10 et, en plus, le bouchon 1 peut être introduit dans un dispositif de decoupe non représenté qui, par exemple,. peut agir au niveau de la gorge 21 prévue sur la partie intermédiaire 4f de la jupe 4. La face supérieure 15a de la bride 15 peut, dans ce cas, servir de face d'appui et de guidage.It should be noted that due to the fact that the gripping tongue 12 is situated inside the cylindrical periphery of the skirt 4, the latter cannot be torn off inadvertently with the tear strip 10 and, in addition, the plug 1 can be introduced into a not shown cutting device which, for example ,. can act at the level of the groove 21 provided on the intermediate part 4f of the skirt 4. The upper face 15a of the flange 15 can, in this case, serve as a bearing and guiding face.

Notons également que lorsqu'il s'agit d'un dispositif de découpe n'agissant que sur la périphérie cylindrique de la jupe 4, le bouchon 1 n'est pas découpé à l'endroit du méplat 14, de sorte que les parties intermédiaire et superieure 4f et 4e du bouchon 1 peuvent être retirées de ce dispositit après la découpe du bouchon 1.Note also that when it is a cutting device acting only on the cylindrical periphery of the skirt 4, the plug 1 is not cut at the location of the flat 14, so that the intermediate parts and upper 4f and 4e of the plug 1 can be removed from this device after the plug 1 has been cut.

Les différents modes de réalisation précédemment décrits peuvent subir un certain nombre de modifications sans que l'on sorte pour cela du cadre de protection défini par les revendications annexées. Ainsi, la paroi frontale d'obturation 3 peut être munie de zones d'affaiblissement 25 qui favorisent la destruction de ladite paroi 3 et qui s'étendent sur celle-ci soit radialement soit suivant au moins une spirale.The various embodiments described above can undergo a number of modifications without departing from the protective framework defined by the appended claims. Thus, the front closure wall 3 can be provided with weakening zones 25 which promote the destruction of said wall 3 and which extend thereon either radially or in at least one spiral.
