Description

L'invention concerne le domaine des capsules et plus spécialement les capsules de bouchage à vis destinées à fermer des récipients ou des bouteilles dont la bague de verrerie comporte un filetage.The invention relates to the field of capsules and more particularly capsules of screw cap intended to close containers or bottles whose ring glassware has a thread.

Ces bouteilles sont typiquement des bouteilles d'apéritifs, de liqueurs, d'alcools, de boissons alcoolisées, dont la consommation est typiquement échelonnée, ce qui nécessite de pouvoir fermer et ouvrir, éventuellement un grand nombre de fois lesdites bouteilles.These bottles are typically bottles of aperitifs, liqueurs, alcohols, alcoholic beverages, the consumption of which is typically staggered, which requires the ability to close and open, possibly a large number of times said bottles.

Ces capsules comprennent le plus souvent une bande d'inviolabilité ou de garantie.These capsules most often include a tamper-evident or guarantee strip.

ETAT DE LA TECHNIQUESTATE OF THE ART

On connaít déjà un grand nombre de capsules de bouchage avec bande de garantie.We already know a large number of caps with guarantee tape.

Certaines de ces capsules sont en matière plastique, comme décrit dans le brevet européen n° 0107 680 au nom de la demanderesse, et typiquement destinées au bouchage de bouteilles d'eau en matière plastique.Some of these capsules are made of plastic, as described in the patent n ° 0107 680 in the name of the plaintiff, and typically intended for capping of plastic water bottles.

D'autres sont métalliques, comme décrites dans le brevet français n° 2 677 333 ou dans les demandes de brevet français n° 9705182 ou 9706009 au nom de la demanderesse, et typiquement destinées au bouchage de bouteilles d'alcools, apéritifs et spiritueux.Others are metallic, as described in French Patent No. 2,677,333 or in French patent applications no. 9705182 or 9706009 in the name of the applicant, and typically intended for corking bottles of alcohol, aperitifs and spirits.

On connaít également le document FR-A1-2 752 560 qui décrit un procédé pour réaliser un bouchon, procédé qui consiste à :

  • mouler par injection une première partie interne définissant un fond, une paroi latérale à filetage interne et une bague d'inviolabilité,
  • surmouler par injection une seconde partie externe formant coque, sur le fond et la paroi latérale de ladite première partie interne.
We also know the document FR-A1-2 752 560 which describes a process for producing a plug, a process which consists in:
  • injection molding a first internal part defining a bottom, a side wall with internal thread and a tamper-evident ring,
  • overmolding by injection a second external part forming a shell, on the bottom and the side wall of said first internal part.

Le préambule de la revendication 1 est basé sur cet état de la technique. The preamble of claim 1 is based on this state of the art.

PROBLEME POSEPROBLEM

Les capsules de bouchage forment une partie importante du conditionnement des liquides et participent pour une part non négligeable à l'aspect final, à l'image du produit conditionné. The closure capsules form an important part of the packaging of liquids and play a significant part in the final appearance, like the conditioned product.

L'invention vise à satisfaire une demande toujours plus grande pour des produits qui permettent une différenciation, une nouveauté de l'esthétique dans un domaine où les contraintes sont nombreuses et où, compte tenu de ces contraintes, les possibilités de modifications sont très limitées.The invention aims to satisfy an ever-increasing demand for products which allow a differentiation, a novelty of aesthetics in a field where constraints are numerous and where, given these constraints, the possibilities of modifications are very limited.

Ces contraintes, outre celles résultant des fonctions d'usage évidentes, sont d'abord des contraintes de fabrication industrielle des capsules à grande cadence, à un coût qui ne soit pas prohibitif.These constraints, in addition to those resulting from obvious usage functions, are first of all constraints of industrial production of capsules at high speed, at a cost that does not is not prohibitive.

Ce sont ensuite des contraintes chez le conditionneur du produit à conditionner. Chez ce dernier, toute modification de la capsule ne doit pas remettre en cause les procédés de conditionnements, les équipements et les cadences de production standard, sauf éventuellement en cas de diminution globale des coûts de production.These are then constraints at the conditioner of the product to be packaged. At this last, any modification of the capsule must not call into question the packaging, equipment and standard production rates, except possibly in the event of an overall reduction in production costs.

A ces contraintes s'ajoutent celles du consommateur final. En matière d'ouverture de récipient ou bouteille, ce dernier a des habitudes ou des possibilités dont on doit toujours tenir compte dans la conception de la capsule de bouchage.To these constraints are added those of the final consumer. In terms of openness container or bottle, the latter has habits or possibilities which one must always take this into account when designing the closure cap.

Ces problèmes sont résolus par la capsule selon la revendication 1.These problems are solved by the capsule according to claim 1.

Sur ces figures, l'étanchéité de la capsule est assurée par un joint rapporté (35), sauf à la figure 3b où elle est assurée par une lèvre d'étanchéité (36).For convenience, two methods have been shown face to face in Figures 1a and 1b, 2a and 2b, 3a and 3b, Sa and 5b, 6a and 6b. In these figures, the sealing of the capsule is ensured by an attached seal (35), except in Figure 3b where it is provided by a lip sealing (36).

    Les figures 7 et 8 sont des coupes transversales perpendiculairement à l'axe (12) de la capsule (1).Figures 7 and 8 are cross sections perpendicular to the axis (12) of the capsule (1).

    Les figures 1a et 2a, de même que les figures 3a, 5a et 6a, correspondent à une première modalité de bande de garantie, avant une première ouverture à la figure 1a et après une première ouverture à la figure 2a, dans laquelle à la fois la jupe intérieure (31) et la jupe extérieure (41) présentent à leur extrémité une série de ponts (33, 42) et une bande de garantie (34, 43).Figures 1a and 2a, as well as Figures 3a, 5a and 6a, correspond to a first guarantee strip modality, before a first opening in FIG. 1a and after a first opening in FIG. 2a, in which both the internal skirt (31) and the skirt outer (41) have at their end a series of bridges (33, 42) and a strip of warranty (34, 43).

    La bande de garantie intérieure (34) comprend une couronne intérieure (340) et des pattes d'accrochage (341) flexibles qui tendent à s'écarter vers le goulot.The interior warranty strip (34) includes an interior crown (340) and flexible hooking lugs (341) which tend to deviate towards the neck.

    La bande de garantie extérieure (43) présente un rebord (430) qui passe au-dessous de l'extrémité basse de la bande de garantie intérieure (34), de sorte qu'à l'ouverture, les deux bandes de garantie (34) et (43) tombent sur le goulot et indiquent clairement qu'une première ouverture a déjà eu lieu.The external guarantee strip (43) has a rim (430) which passes below the lower end of the interior guarantee strip (34), so that, when opened, the two guarantee strips (34) and (43) fall on the neck and clearly indicate that a first opening has already taken place.

    Les figures 1b et 2b, de même que les figures 3b, 5b et 6b, correspondent à une seconde modalité de bande de garantie, avant une première ouverture à la figure 1b et après une première ouverture à la figure 2b, dans laquelle seule la jupe intérieure (31) présente une série de ponts (33) et une bande de garantie (34). Dans ce cas, la jupe extérieure (41) est suffisamment longue pour cacher la bande de garantie (34) avant la première ouverture, mais suffisamment courte pour que, les ponts (33) une fois rompus, la bande de garantie devienne visible (sur la figure 2b) et indique clairement qu'une première ouverture a déjà eu lieu.Figures 1b and 2b, as well as Figures 3b, 5b and 6b, correspond to a second guarantee strip modality, before a first opening in FIG. 1b and after a first opening in FIG. 2b, in which only the inner skirt (31) has a series of bridges (33) and a guarantee strip (34). In this case, the outer skirt (41) is long enough to hide the guarantee strip (34) before the first opening, but short enough so that, once the bridges (33) are broken, the guarantee strip becomes visible (in Figure 2b) and clearly indicates that a first opening has already happened.

    Sur les figures la à 2b, ladite partie extérieure (4) recouvre entièrement ladite partie intérieure (3) et a typiquement une forme cylindrique, la tête (40) étant plate, et la jupe (41) étant cylindrique.In Figures la to 2b, said outer part (4) completely covers said part interior (3) and typically has a cylindrical shape, the head (40) being flat, and the skirt (41) being cylindrical.

    Les figures 3a, 3b, 5a, 5b, 6a, 6b et 7 sont notamment relatives à des variantes de ladite partie extérieure (4).Figures 3a, 3b, 5a, 5b, 6a, 6b and 7 relate in particular to variants of said external part (4).

    Figure 3a : la partie extérieure (4) forme une tête de champignon.Figure 3a: the outer part (4) forms a mushroom head.

    Figure 3b : ladite jupe extérieure (41) présente un profil à deux segments de droites raccordés.Figure 3b: said outer skirt (41) has a profile with two straight segments connected.

    Cette partie extérieure peut être soit en matière plastique moulée, soit en métal embouti puis assemblé à ladite jupe intérieure (31).This outer part can be either molded plastic or stamped metal then assembled to said inner skirt (31).

    Figure 5a et 5b : ladite partie extérieure (4) se limite à une jupe extérieure (41), qui recouvre ladite jupe intérieure (31) en totalité à la figure 5a, et en majeure partie à la figure 5b, le diamètre de ladite partie intérieure (3) étant un plus grand là où ladite jupe extérieure (41) est absente de manière à ce que ladite capsule ait une jupe (11) cylindrique de même rayon sur toute sa hauteur.Figure 5a and 5b: said outer part (4) is limited to an outer skirt (41), which covers said inner skirt (31) entirely in FIG. 5a, and mainly in the Figure 5b, the diameter of said inner part (3) being greater where said skirt outer (41) is absent so that said capsule has a skirt (11) cylindrical with the same radius over its entire height.

    Figures 6a et 6b : ladite tête intérieure (30) est recouverte partiellement par ladite tête extérieure (40).Figures 6a and 6b: said inner head (30) is partially covered by said head exterior (40).

    A la figure 6a, l'épaisseur de la tête intérieure (30) est augmentée là où la tête extérieure (40) est absente pour obtenir une tête plane (10) uniforme, contrairement au cas de la figure 6b.In Figure 6a, the thickness of the inner head (30) is increased where the outer head (40) is absent to obtain a uniform flat head (10), unlike the case of the Figure 6b.

    Figure 7 : ladite jupe extérieure (41) présente une forme quelconque non cylindrique.Figure 7: said outer skirt (41) has any non-cylindrical shape.

    Les figures 4a à 4e représentent des portions de jupes intérieure (31) et extérieure (41) et illustrent des modalités d'assemblage desdites parties intérieure (31) et extérieure (41) à l'aide de moyens d'ancrage circulaires (44) formés par coopération d'éléments circulaires mâles sur une partie, avec des éléments femelles sur l'autre partie en regard, de manière à supprimer la possibilité d'un déplacement relatif, dans le sens axial, entre ladite partie intérieure (3) et ladite partie extérieure (4).FIGS. 4a to 4e represent portions of inner (31) and outer (41) skirts and illustrate methods of assembling said inner (31) and outer (41) parts to using circular anchoring means (44) formed by cooperation of elements male circulars on one part, with female elements on the other part opposite, so as to eliminate the possibility of a relative movement, in the axial direction, between said inner part (3) and said outer part (4).

    La figure 8 illustre une modalité d'assemblage desdites parties intérieure (31) et extérieure (41) à l'aide de moyens d'ancrage verticaux ou axiaux (45) formés par coopération de nervures axiales sur la surface extérieure de ladite jupe intérieure (31) avec des rainures axiales sur la surface intérieure de ladite jupe extérieure (41), de manière à solidariser en rotation, par un moyen mécanique, lesdites parties intérieure (3) et extérieure (4).FIG. 8 illustrates a method of assembling said interior parts (31) and exterior (41) using vertical or axial anchoring means (45) formed by cooperation of axial ribs on the outer surface of said inner skirt (31) with axial grooves on the inner surface of said outer skirt (41), so as to secure in rotation, by mechanical means, said inner parts (3) and exterior (4).

    Les figures 9a et 9b illustrent une modalité d'assemblage dans laquelle la jupe intérieure (31) présente sur sa surface extérieure un évidemment cylindrique (37) dans lequel peut être emmanché une jupe (41).Figures 9a and 9b illustrate an assembly method in which the inner skirt (31) has on its outer surface a cylindrical recess (37) in which can to be fitted a skirt (41).

    Les figures 10a et 10b illustrent une autre modalité de l'invention dans laquelle ladite partie extérieure (4) est elle-même composite et constituée d'un assemblage d'une tête (400) et d'une jupe (410), le matériau constituant ladite tête (400) et celui constituant ladite jupe (410) pouvant être les mêmes ou être différents, ce qui augmente encore les possibilités de créations. Figures 10a and 10b illustrate another method of the invention in which said outer part (4) is itself composite and consists of an assembly of a head (400) and a skirt (410), the material constituting said head (400) and that constituting said skirt (410) can be the same or be different, which further increases the possibilities of creations.

    Les figures 11a à 11d illustrent des possibilités de décor par traitement de surface localisé d'une jupe en aluminium, de manière à obtenir un contraste de couleur, de brillant, de rugosité, en un mot d'aspect, entre les partie hachurées (410) et le fond (411) non hachuré.FIGS. 11a to 11d illustrate possibilities of decoration by surface treatment located with an aluminum skirt, so as to obtain a color contrast, shiny, roughness, in a word of appearance, between the hatched parts (410) and the bottom (411) not hatched.

    Les figures 12a à 12f sont des vues en coupe axiale partielle (figure 12a) ou agrandies (12b à 12f) qui illustrent des modalités de moyens de compression radial et/ou axial destinés à augmenter l'étanchéité :Figures 12a to 12f are partial axial section views (Figure 12a) or enlarged (12b to 12f) which illustrate modalities of radial and / or axial compression means intended to increase the tightness:

    La figure 12a illustre deux modalités d'un moyen de compression radiale.Figure 12a illustrates two modalities of a radial compression means.

    Dans la modalité représentée à la partie gauche de la figure 12a, qui est agrandie à la figure 12b, le moyen de compression forme une marche d'escalier avec Ea > Er, et la tête intérieure a la forme d'un bord annulaire qui recouvre sensiblement le buvant (22) du goulot.In the modality shown on the left side of Figure 12a, which is enlarged at the FIG. 12b, the compression means forms a stair step with Ea> Er, and the inner head in the form of an annular edge which substantially covers the rim (22) bottleneck.

    Par contre, dans la modalité représentée à la partie droite de la figure 12a, qui est agrandie à la figure 12c, le moyen de compression forme une marche d'escalier avec Ea voisin de Er, et la tête intérieure (30) est pleine.On the other hand, in the modality represented on the right part of figure 12a, which is enlarged in FIG. 12c, the compression means forms a stair step with Ea neighbor of Er, and the inner head (30) is full.

    La figure 12d illustre un exemple de compression axiale à l'aide d'une nervure circulaire (300). Une nervure circulaire ou rebord de maintien (312) permet au joint de rester solidaire de la capsule avant utilisation.Figure 12d illustrates an example of axial compression using a rib circular (300). A circular rib or retaining flange (312) allows the seal to remain attached to the capsule before use.

    La figure 12e illustre un exemple d'insert assurant une compression radiale avec une partie rayonnée (311), l'insert étant dépourvu de tête intérieure.Figure 12e illustrates an example of an insert ensuring radial compression with a radiated part (311), the insert having no internal head.

    La figure 12f illustre un exemple d'insert assurant une compression radiale avec un moyen de compression solidaire de ladite tête intérieure (30) et non de ladite jupe (31). FIG. 12f illustrates an example of an insert ensuring radial compression with a compression means integral with said inner head (30) and not with said skirt (31).

    DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

    Selon l'invention, ladite partie extérieure (4) peut comprendre une jupe (41), et éventuellement une tête (40), dite extérieure.According to the invention, said outer part (4) can comprise a skirt (41), and possibly a head (40), said to be external.

    La plupart des figures illustrent cette modalité.Most of the figures illustrate this modality.

    Cependant, des effets décoratifs spéciaux pourraient être obtenus dans le cas où la jupe de la capsule (1) serait constituée pour partie d'une portion de ladite jupe intérieure (31) et pour partie d'une portion de la dite jupe extérieure (41), comme ce serait le cas à la figure 5b avec une jupe extérieure (41) plus courte.However, special decorative effects could be obtained in the case where the skirt of the capsule (1) would partly consist of a portion of said inner skirt (31) and part of a portion of said outer skirt (41), as would be the case with Figure 5b with a shorter outer skirt (41).

    Typiquement, ladite partie extérieure (4) peut présenter une jupe (41) droite, typiquement cylindrique, ce qui correspond au cas le plus courant, mais l'invention permet aussi justement de créer des capsules de forme originale, à jupe (11) droite non cylindrique comme représenté en coupe à la figure 7, ou à jupe non droite, comme représenté à la figure 3a.Typically, said outer part (4) may have a straight skirt (41), typically cylindrical, which corresponds to the most common case, but the invention also allows you to create capsules of original shape, with a straight skirt (11) not cylindrical as shown in section in FIG. 7, or with a non-straight skirt, as shown in Figure 3a.

    Ladite partie extérieure (4) peut former une surface de révolution, de rayon constant ou non selon la hauteur considérée, comme illustré à la figure 3a.Said outer part (4) can form a surface of revolution, of constant radius or not according to the height considered, as illustrated in Figure 3a.

    Dans tous les cas, ladite partie extérieure (4), de forme extérieure quelconque, est solidarisée à ladite partie intérieure (3) et pour cela, ladite partie extérieure (4) et ladite partie intérieure (3) utilisent comme moyen dudit assemblage, un moyen d'ancrage, mécanique (44,45) ou chimique, typiquement par collage.In all cases, said external part (4), of any external form, is secured to said inner part (3) and for this, said outer part (4) and said inner part (3) use as means of said assembly, an anchoring means, mechanical (44,45) or chemical, typically by bonding.

    Des moyens d'ancrage mécaniques ont été représentés aux figures 4a à 4e et 8. Les parties intérieure (3) et extérieure (4) peuvent aussi être assemblées par encliquetage ou clipsage, les matériaux et/ou l'épaisseur des parties (3) et (4) pouvant permettre une élasticité et des effets ressorts permettant leur assemblage.Mechanical anchoring means have been shown in Figures 4a to 4e and 8. The interior (3) and exterior (4) parts can also be snap-fitted or clipping, the materials and / or the thickness of the parts (3) and (4) being able to allow a elasticity and spring effects allowing their assembly.

    Sur les autres figures, le moyen d'ancrage n'a pas été représenté, car il est constitué par un collage, à l'aide d'une couche d'adhésif, ou un thermoscellage, de tout ou partie de ladite partie intérieure (3) sur tout ou partie de ladite partie extérieure (4). In the other figures, the anchoring means has not been shown, since it consists of bonding, using a layer of adhesive, or heat sealing, all or part of said inner part (3) over all or part of said outer part (4).

    Selon l'invention, ladite partie intérieure (3) peut être un insert en PP, doté d'un filetage intérieur (32), dont la bande de garantie (34) comprend des pattes d'accrochage (341). Un tel insert peut être obtenu par moulage ou injection de PP. Il est possible d'obtenir un tel insert plastique comme décrit dans le brevet européen n° 107 680 au nom de la demanderesse.According to the invention, said inner part (3) can be a PP insert, provided with a thread interior (32), the guarantee strip (34) of which includes hooking lugs (341). Such an insert can be obtained by molding or injection of PP. It is possible to get such a plastic insert as described in European Patent No. 107,680 in the name of Applicant.

    Selon une modalité de l'invention, ladite partie extérieure (4) peut être métallique, ou comprendre intérieurement une partie métallique, et être fixée audit insert (3), par collage.According to one embodiment of the invention, said external part (4) can be metallic, or internally comprise a metal part, and be fixed to said insert (3), by bonding.

    Dans ce cas, ladite partie extérieure (4) peut être en aluminium traité en surface, typiquement brossé ou anodisé, pour créer une apparence ou une couleur " métallique ".In this case, said outer part (4) can be made of surface-treated aluminum, typically brushed or anodized, to create a "metallic" appearance or color.

    Selon une autre modalité de l'invention, ladite partie extérieure (4) peut être en matière plastique, typiquement en polystyrène, et être fixée audit insert par assemblage mécanique ou par collage. De préférence, ladite partie (4) extérieure en matière plastique est métallisée.According to another embodiment of the invention, said external part (4) can be made of plastic, typically made of polystyrene, and be fixed to said insert by assembly mechanical or by bonding. Preferably, said outer part (4) in material plastic is metallized.

    Que ce soit par utilisation d'aluminium traité en surface ou par métallisation d'une matière plastique, I'invention permet d'obtenir une très grande variété d'effets décoratifs.Whether by using surface treated aluminum or by metallizing a plastic material, the invention provides a very wide variety of effects decorative.

    Les capsules selon l'invention peuvent comprendre tout type de bande de garantie connu en lui-même. Typiquement, ladite bande de garantie (34) comprend une couronne intérieure (340) munie d'éléments d'accrochage (341), typiquement des pattes ou crochets, tournés vers l'intérieur de ladite capsule, et encliquetés sous ladite bague (20), de manière à ce que, lors de ladite première ouverture, les ponts (33) se rompent, ladite bande de garantie (34) étant empêchée de se déplacer vers le haut grâce à la coopération desdits éléments (341) avec ladite bague (20). de manière à ce que ladite bande de garantie (34), séparée du reste de ladite capsule, soit la preuve visible de ladite première ouverture.The capsules according to the invention can comprise any type of known guarantee strip in himself. Typically, said guarantee strip (34) comprises a crown interior (340) provided with hooking elements (341), typically legs or hooks, turned towards the inside of said capsule, and snapped under said ring (20), so that, during said first opening, the bridges (33) break, said guarantee strip (34) being prevented from moving upward by cooperation said elements (341) with said ring (20). so that said strip of guarantee (34), separated from the rest of the said capsule, ie visible proof of the said first opening.

    Un exemple de bande de garantie, parmi de nombreux autres connus, est donné dans le brevet européen n° 107 680. An example of a guarantee band, among many others known, is given in the European Patent No. 107,680.

    Dans les cas de capsules illustrées aux figures 1b, 3b, 5b et 6b, la jupe extérieure (41) masque ladite bande de garantie (34), avant la première ouverture. Mais, à la première ouverture, durant laquelle les ponts (33) sont rompus, la bande de garantie, séparée du reste de la jupe, tombe et descend de quelques millimètres sur le goulot et devient de ce fait visible, même sur une bouteille fermée, comme illustré à la figure 2b.In the cases of capsules illustrated in FIGS. 1b, 3b, 5b and 6b, the outer skirt (41) mask said guarantee strip (34), before the first opening. But at the first opening, during which the bridges (33) are broken, the guarantee strip, separated from the rest of the skirt, falls and descends a few millimeters on the neck and becomes made visible, even on a closed bottle, as shown in Figure 2b.

    Selon une autre modalité illustrée notamment aux figures 1a et 1b, ladite jupe extérieure (41). tout comme la jupe intérieure (31), comprend des ponts (42) la reliant à une couronne (43) dite extérieure, ladite couronne extérieure étant bloquée vers le haut par ladite couronne intérieure (340), typiquement grâce à un rebord inférieur (430) de ladite couronne extérieure (43), de sorte que, lors de ladite première ouverture, les couronnes extérieure (43) et intérieure (340) soient séparées du reste de ladite capsule.According to another method illustrated in particular in Figures 1a and 1b, said outer skirt (41). just like the inner skirt (31), includes bridges (42) connecting it to a said outer ring (43), said outer ring being blocked upwards by said inner ring (340), typically thanks to a lower rim (430) of said outer crown (43), so that, when said first opening, the crowns exterior (43) and interior (340) are separated from the rest of said capsule.

    Dans tous les cas, la bague (20), en bloquant, lors du premier dévissage, les pattes d'accrochage (341) ou tout élément d'une bande de garantie de ladite partie intérieure (3) remplissant une fonction équivalente, entraíne la rupture des ponts (33), puis éventuellement celle des ponts (42), et donc la chute sur le goulot de la bouteille de la bande de garantie - ce qui permet de voir, de manière non équivoque, qu'une première ouverture a déjà bien eu lieu.In all cases, the ring (20), by blocking, during the first unscrewing, the tabs of attachment (341) or any element of a guarantee strip of said interior part (3) fulfilling an equivalent function, causes the bridges to break (33), then possibly that of the bridges (42), and therefore the fall on the neck of the bottle of the guarantee strip - which makes it possible to see, unequivocally, that a first opening has already taken place.

    Les capsules selon l'invention peuvent comprendre tout moyen de bouchage connu en lui-même, typiquement par l'emploi soit d'une lèvre circulaire (36) solidaire de ladite tête intérieure, comme illustré à la figure 3b, soit d'un joint rapporté (35) comme illustré sur les autres figures relatives à la capsule (1).The capsules according to the invention can comprise any means of closure known in itself, typically by the use of either a circular lip (36) integral with said inner head, as illustrated in FIG. 3b, or of an attached seal (35) as illustrated in the other figures relating to the capsule (1).

    Plus précisément, les capsules peuvent comprendre, en vue d'assurer l'étanchéité du récipient une fois bouché, un joint rapporté (35) de diamètre suffisant pour recouvrir leMore specifically, the capsules may include, in order to ensure the tightness of the container closed, a gasket (35) of sufficient diameter to cover the

    buvant (22) du goulot (2) et un moyen de compression axial et/ou radial porté par la surface intérieure dudit insert, pour appliquer de manière étanche ledit joint sur le buvant (22) dudit goulot (2) lors dudit bouchage. drinking (22) from the neck (2) and an axial and / or radial compression means carried by the inner surface of said insert, for sealingly applying said seal to the drinking (22) of said neck (2) during said plugging.

    Un moyen de compression est dit axial lorsqu'il s'applique sur la partie supérieure (220) du buvant, et il est dit radial dans les autres cas, lorsqu'il s'applique soit sur la partie rayonnée (221) soit sur la partie verticale (222) du buvant, comme illustré à la figure 12d.A compression means is said to be axial when it is applied to the upper part (220) of the drink, and it is said to be radial in the other cases, when it is applied either on the part radiated (221) either on the vertical part (222) of the rim, as illustrated in the figure 12d.

    Ledit moyen de compression axial peut comprendre une nervure circulaire (300) formée sur la paroi intérieure de ladite tête intérieure (30) destinée à comprimer ledit joint sur la partie supérieure (220) dudit buvant (22), typiquement plane, comme illustré à la figure 12d.The axial compression means may include a circular rib (300) formed on the inner wall of said inner head (30) intended to compress said seal on the upper part (220) of said drink (22), typically flat, as illustrated in the figure 12d.

    Ledit moyen de compression radial peut comprendre une surépaisseur annulaire (310,302) formée sur ladite jupe intérieure (31) ou sur ladite tête intérieure (30), typiquement au niveau de la jonction (301) entre la tête intérieure (30) et la jupe intérieure (31), et destinée à comprimer ledit joint sur tout ou partie de la partie rayonnée (221), typiquement inclinée, et/ou sur la partie radiale (222), typiquement verticale, du buvant (22). Cette surépaisseur peut être solidaire de la jupe intérieure (31), comme illustré aux figures 12a à 12e avec le repère "310", ou solidaire de la tête intérieure (30), comme illustré à la figure 12f avec le repère " 302 ".Said radial compression means may include an annular allowance (310.302) formed on said inner skirt (31) or on said inner head (30), typically at the junction (301) between the inner head (30) and the skirt interior (31), and intended to compress said seal over all or part of the part radiated (221), typically inclined, and / or on the radial part (222), typically vertical, from the drink (22). This additional thickness may be integral with the inner skirt (31), as illustrated in FIGS. 12a to 12e with the reference "310", or integral with the head interior (30), as illustrated in FIG. 12f with the reference "302".

    Selon une variante illustrée sur les figures 12a à 12d, ladite surépaisseur annulaire (310) peut avoir la forme d'une marche d'escalier annulaire placée à l'angle annulaire intérieur formé à la jonction de la tête intérieure (30) et la jupe intérieure (31).According to a variant illustrated in FIGS. 12a to 12d, said annular allowance (310) may be in the form of an annular staircase placed at the annular angle interior formed at the junction of the interior head (30) and the interior skirt (31).

    Selon une autre variante illustrée à la figure 12b, ladite tête intérieure (30) peut comprendre un bord annulaire (38) avec une partie centrale ajourée, typiquement en regard de l'orifice (23) dudit goulot (2). Cette variante permet d'économiser du poids et de la matière pour l'insert plastique (3), en particulier dans le cas d'un moyen de compression radial.According to another variant illustrated in FIG. 12b, said inner head (30) can comprise an annular edge (38) with a perforated central part, typically in look of the orifice (23) of said neck (2). This variant saves weight and material for the plastic insert (3), in particular in the case of a means of radial compression.

    En effet, la demanderesse a pu constater que, plus l'effort de compression est de type radial, plus il est possible de diminuer l'épaisseur de ladite tête intérieure (30).Indeed, the Applicant has been able to observe that the more the compression force is of the type radial, the more it is possible to reduce the thickness of said inner head (30).

    Dans ce cas, comme illustré à la figure 12e, la capsule présente les caractéristiques suivantes :

  • a) ladite tête intérieure (30) présente une épaisseur allant de 0 à 0,5 mm,
  • b) ledit moyen de compression est typiquement radial, et
  • c) ce moyen de compression présente une partie rayonnée (311) présentant une courbure typiquement voisine de celle de la partie rayonnée (221) dudit buvant qui est en regard.
    • In this case, as illustrated in FIG. 12e, the capsule has the following characteristics:
  • a) said inner head (30) has a thickness ranging from 0 to 0.5 mm,
  • b) said compression means is typically radial, and
  • c) this compression means has a radiated part (311) having a curvature typically close to that of the radiated part (221) of said drink which is opposite.

    • Cette modalité permet de diminuer la hauteur de la capsule typiquement de 1 à 2 mm, ce qui peut être très utile en pratique, compte tenu des contraintes de la normalisation dans ce domaine de l'emballage.This modality makes it possible to decrease the height of the capsule typically from 1 to 2 mm, this which can be very useful in practice, given the constraints of standardization in this area of packaging.

    L'homme du métier peut adapter la forme et les dimensions exactes de l'insert et des moyens de compression axial et/ou radial, par exemples les épaisseurs Ea et Er comme illustré à la figure 12b. En effet, il peut choisir l'épaisseur dudit moyen de compression, en fonction notamment de l'épaisseur Ej du joint et de l'espace Eo entre ledit goulot et ladite capsule, pour que ledit récipient soit bouché de manière étanche par ladite capsule, l'épaisseur du joint localement comprimé ou la distance E entre l'extrémité dudit moyen de compression et ledit buvant étant alors typiquement comprise entre 0,2.Ej et 0,7.Ej, avec Ej typiquement compris entre 1 et 2,5 mm.A person skilled in the art can adapt the exact shape and dimensions of the insert and the axial and / or radial compression means, for example the thicknesses Ea and Er as illustrated in Figure 12b. In fact, he can choose the thickness of said compression means, depending in particular on the thickness Ej of the joint and the space Eo between said neck and said capsule, so that said container is sealed by said capsule, the thickness of the locally compressed joint or the distance E between the end said compression means and said drink then typically being between 0.2 EJ and 0.7 EJ, with Ej typically between 1 and 2.5 mm.
