Description

La présente invention concerne un procédé de fabrication d'une capsule de surbouchage, c'est-à-dire d'une capsule munie d'une jupe cylindrique dont le bord est destiné à être serti sur la bague du goulot d'une bouteille déjà équipée d'un bouchon de fermeture. La présente invention concerne également une capsule de surbouchage obtenu par un tel procédé.The present invention relates to a method for manufacturing an overcapping cap, that is to say a cap provided with a cylindrical skirt, the edge of which is intended to be crimped onto the ring of the neck of a bottle already fitted with a closure cap. The present invention also relates to an overcap capsule obtained by such a process.

Lors de l'ouverture d'une bouteille ainsi fermée, il est d'usage de ne retirer que le sommet de la capsule en laissant subsister sa jupe, ce qui, si l'on désire une découpe propre et nette, nécessite l'emploi d'un couteau.When opening a closed bottle, it is customary to remove only the top of the capsule, leaving its skirt, which, if you want a clean and neat cut, requires the use with a knife.

Pour permettre d'atteindre ce résultat, on a utilisé des capsules de surbouchage munies d'une jupe cylindrique dont le bord est destiné à être serti sur la bague du goulot d'une bouteille déjà équipée d'un bouchon de fermeture et dans la jupe de laquelle il est prévu, au niveau souhaité de sa découpe, une bande pré-découpée de forme annulaire présentant, de part et d'autre d'une interruption, des extrémités conformées en deux languettes de préhension disposées symétriquement par rapport à ladite interruption. Une capsule de ce genre est décrite dans le brevet CH-A-345 552.To achieve this result, overcap capsules were used fitted with a cylindrical skirt, the edge of which is intended to be crimped onto the neck of the neck of a bottle already fitted with a closure cap and into the skirt. from which there is provided, at the desired level of its cutting, a pre-cut strip of annular shape having, on either side of an interruption, ends shaped into two gripping tabs arranged symmetrically with respect to said interruption. A capsule of this kind is described in patent CH-A-345,552.

La présence des deux languettes de préhension a pour avantage d'éviter d'appliquer un couple sur la capsule et de l'entraîner en rotation puisque lors du déchirage de la capsule, l'opérateur agit simultanément et symétriquement sur les deux languettes.The presence of the two gripping tabs has the advantage of avoiding applying a torque to the capsule and of driving it in rotation since during the tearing of the capsule, the operator acts simultaneously and symmetrically on the two tabs.

Toutefois, dans certaines capsules, telle que celle révélée par le brevet 345.552 précité, pour faciliter la préhension des languettes, on a prévu des aspérités telles que des ondulations ou autres déformations obtenues par gaufrage ou moletage ou de toute autre manière appropriée.However, in certain capsules, such as that disclosed by the aforementioned patent 345,552, to facilitate the gripping of the tongues, roughness is provided such as undulations or other deformations obtained by embossing or knurling or in any other appropriate manner.

Ces perfectionnements, bien que facilitant le déchirage de la capsule, ont l'inconvénient d'en renchérir considérablement le prix de revient. En effet, pour réaliser ces ondulations ou autres sur les languettes qui seules en sont pourvues, il est nécessaire d'effectuer une reprise de la capsule après avoir réalisé, par exemple, la présente découpe de la bande et la découpe des languettes et il faut aussi repérer la position des languettes pour réaliser les ondulations uniquement sur elles.These improvements, although facilitating the tearing of the capsule, have the drawback of considerably increasing the cost price. Indeed, to achieve these undulations or others on the tongues which alone are provided with it, it is necessary to carry out a recovery of the capsule after having carried out, for example, the present cutting of the strip and the cutting of the tongues and it is necessary also locate the position of the tabs to make the corrugations only on them.

La présente invention vise à remédier à cet inconvénient. A cet effet, suivant le procédé de fabrication d'une capsule du type énoncé dans le préambule de la revendication 1 (et du type décrit dans le brevet CH-A-345 552), les aspérités que présente chaque languette sont réalisées par moletage ou moulurage, avant le découpage desdites languettes, sur toute la longueur de la bande pré-découpée. La présente invention a également pour objet une capsule de surbouchage du type énoncé dans le préambule de la revendication 2 (et du type décrit dans le brevet CH-A-345 552), caractérisé en ce qu'elle est fabriquée par le procédé ci-dessus défini et qu'elle présente des aspérités sur toute la longueur de la bande prédécoupée.The present invention aims to remedy this drawback. To this end, according to the method of manufacturing a capsule of the type set out in the preamble of claim 1 (and of the type described in patent CH-A-345 552), the roughness of each tongue is produced by knurling or molding, before cutting said tabs, over the entire length of the pre-cut strip. The present invention also relates to an overcap capsule of the type stated in the preamble of claim 2 (and of the type described in patent CH-A-345 552), characterized in that it is produced by the process below. defined top and has roughness along the entire length of the precut strip.

Naturellement, pour diminuer encore les risques de rotation de la capsule, lors du déchirage de sa bande pré-découpée, on peut prévoir des moyens améliorant sa liaison en rotation au goulot de la bouteille, par exemple à l'aide d'un revêtement intérieur permettant son collage ou son scellage ou créant une forte friction.Naturally, to further reduce the risks of rotation of the capsule, during the tearing of its pre-cut strip, one can provide means improving its connection in rotation to the neck of the bottle, for example using an inner coating allowing its bonding or its sealing or creating a strong friction.

Dans le cas où le goulot de la bouteille présente un évidement, on peut aussi prévoir une déformation de la capsule formant un ergot qui pénètre dans ledit évidement.In the case where the neck of the bottle has a recess, it is also possible to provide for a deformation of the capsule forming a lug which penetrates into said recess.

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 cette capsule de surbouchage.

  • Figure 1 est une vue en élévation avant sertissage sur le goulot d'une bouteille.
  • Figure 2 est une vue en coupe axiale du goulot d'une bouteille équipée de cette capsule.
In any case, the invention will be clearly understood with the aid of the description which follows with reference to the appended schematic drawing showing by way of nonlimiting example an embodiment of this overcap capsule.
  • Figure 1 is an elevational view before crimping on the neck of a bottle.
  • Figure 2 is an axial sectional view of the neck of a bottle equipped with this cap.

Comme le montre le dessin, la capsule 2 selon l'invention est du type présentant un sommet plan 2a permettant sa fiscalisation et une jupe cylindrique 2b apte à être engagée sur le goulot 3a d'une bouteille 3 préalablement fermée par un bouchon 4. La collerette 2c que la capsule 2 présente à l'extrémité libre de sa jupe 2b n'est prévue que pour des facilités de distribution des capsules dans les machines servant à leur mise en place sur les bouteilles. Cette capsule 2 est donc destinée à être sertie sur le goulot 3a et plus particulièrement au-dessous de la bague 3b que présente ce goulot 3a.As the drawing shows, the capsule 2 according to the invention is of the type having a flat top 2a allowing it to be taxed and a cylindrical skirt 2b capable of being engaged on the neck 3a of a bottle 3 previously closed by a stopper 4. The flange 2c that the capsule 2 has at the free end of its skirt 2b is only provided for ease of dispensing the capsules in the machines used to place them on the bottles. This capsule 2 is therefore intended to be crimped onto the neck 3a and more particularly below the ring 3b that this neck 3a has.

Pour permettre sa réalisation avec un matériau d'un bas prix de revient, telle qu'une feuille d'aluminium, cette capsule 2 présente, dans sa jupe cylindrique 2b, une bande pré-découpée 5 de forme annulaire et présentant une interruption 6 d'où il résulte la préhension de deux extrémités 5a dans cette bande 5. Comme le montre la figure 1, chaque extrémité 5a est conformée en languette de préhension, c'est-à-dire qu'elle est détachée latéralement des deux parties de la jupe cylindrique 2b qui l'encadre.To allow its realization with a material of a low cost price, such as aluminum foil, this capsule 2 has, in its cylindrical skirt 2b, a pre-cut strip 5 of annular shape and having an interruption 6 d 'where it results in the gripping of two ends 5a in this strip 5. As shown in Figure 1, each end 5a is shaped as a gripping tab, that is to say that it is detached laterally from the two parts of the cylindrical skirt 2b which frames it.

On comprend aisément que, lors du déchirage de la capsule 2, en agissant simultanément sur les deux languettes 5a, on ne crée aucun couple tendant à faire pivoter la capsule 2 sur le goulot 3a, ce qui ne serait pas le cas si cette capsule ne présentait q'une seule languette de préhension et non deux languettes disposées symétriquement de part et d'autre de l'interruption 6 de la bande 5.It is easily understood that, during the tearing of the capsule 2, by acting simultaneously on the two tabs 5a, no torque is created tending to rotate the capsule 2 on the neck 3a, which would not be the case if this capsule does not had only one gripping tab and not two tongues arranged symmetrically on either side of the interruption 6 of the strip 5.

Grâce à cette disposition, il n'est pas non plus nécessaire de prévoir une jupe 2b s'étendant bien au-delà du bord inférieur de la bague 3b du goulot 3a de la bouteille 3.Thanks to this arrangement, it is also not necessary to provide a skirt 2b extending well beyond the lower edge of the ring 3b of the neck 3a of the bottle 3.

Comme le montre également la figure 1, pour faciliter le déchirage de cette capsule en améliorant la tenue de ces languettes 5a entre les doigts de l'utilisateur, chacune d'elles est ondulée transversalement ce qui, en raccourcissant leur longueur, augmente la largeur de l'interruption 6 et facilite encore leur préhension.As also shown in Figure 1, to facilitate the tearing of this capsule by improving the holding of these tabs 5a between the fingers of the user, each of them is corrugated transversely which, by shortening their length, increases the width of the interruption 6 and further facilitates their gripping.

Il faut noter que ces languettes 5a ne sont pas en saillie par rapport à la jupe 2b de la capsule 2 et, par conséquent, ne perturbent pas le fonctionnement des machines de distribution des capsules sur les bouteilles.It should be noted that these tongues 5a are not protruding with respect to the skirt 2b of the capsule 2 and, consequently, do not disturb the operation of the machines for dispensing the capsules on the bottles.

Comme représenté en traits mixtes sur la figure 1, dans un but de simplification considérable de la fabrication de cette capsule, non seulement les languettes 5a sont pourvues d'aspérités telles que des ondulations transversales mais toute la bande 5. En effet, il est plus facile de réaliser le formage de ces aspérités par moletage ou moulurage avant le découpage desdites languettes.As shown in phantom in Figure 1, in order to considerably simplify the manufacture of this capsule, not only the tabs 5a are provided with roughness such as transverse undulations but the entire strip 5. In fact, it is more easy to perform the forming of these asperities by knurling or molding before cutting said tabs.

Si on le souhaite, il est évidemment possible d'améliorer la liaison en rotation de la capsule 2 sur le goulot 3a, par exemple, en prévoyant un revêtement intérieur permettant son collage ou son séchage, ou tout au moins présentant un fort coefficient de frottement par rapport à la matière dont est constitué ledit collage.If desired, it is obviously possible to improve the rotational connection of the capsule 2 on the neck 3a, for example, by providing an inner coating allowing it to be bonded or dried, or at least having a high coefficient of friction. compared to the material of which said collage is made.

Dans le même but, on pourrait prévoir tout aussi bien un évidement dans le goulot 3a, par exemple une encoche de sa bague 3b et une déformation de la jupe 2b de la capsule 2 formant un ergot susceptible de pénétrer dans l'évidement précité.For the same purpose, one could just as well provide a recess in the neck 3a, for example a notch in its ring 3b and a deformation of the skirt 2b of the capsule 2 forming a lug capable of entering the aforementioned recess.
