Description

La présente invention se rapporte à un ensemble verseur et capsule de bouchage en matière plastique, pour des bouteilles ou des récipients analogues, comprenant un verseur avec des moyens pour sa fixation à un goulot de bouteile ou un orifice de récipient analogue, une capsule rapportée de façon amovible sur le verseur de manière à coiffer et obturer ce dernier, et des moyens d'inviolabilité comprenant une bande de garantie reliée de façon arrachable au verseur et coopérant avec la capsule de manière à interdire l'enlèvement de la capsule sans arrachage préalable de la bande de garantie.The present invention relates to a pouring assembly and closure cap made of plastic material, for bottles or similar containers, comprising a pouring device with means for its attachment to a bottle neck or a similar container orifice, an attached capsule of removably on the pourer so as to cover and close the latter, and tamper-proof means comprising a guarantee strip detachably connected to the pourer and cooperating with the capsule so as to prohibit the removal of the capsule without prior removal from the warranty strip.

Sur les ensembles verseurs et capsules de bouchage connus de ce type, la capsule est retenue sur le verseur par encliquetage ou par vissage, et la bande de garantie s'étend depuis le verseur vers le haut sur une partie plus ou moins importante de la hauteur de la capsule. Le but de cette bande de garantie est d'empêcher le plus possible la préhension de la capsule, et de ce fait la possibilité, de retirer la capsule du verseur sans arracher ou abîmer cette bande. L'inviolabilité que procurent ces ensembles connus n'est pas toujours satisfaisante, notamment dans le cas où la capsule est retenue sur le verseur, non pas par vissage ou par encliquetage, mais simplement par le serrage exercé sur le bec verseur par une jupe interne d'étanchéité formée sur la capsule de manière à coopérer par forçage avec le bec verseur.On known pouring assemblies and caps of this type, the capsule is retained on the pourer by snap-fastening or by screwing, and the guarantee strip extends from the pourer upwards over a greater or lesser part of the height. of the capsule. The purpose of this guarantee strip is to prevent gripping of the capsule as much as possible, and therefore the possibility of removing the capsule from the pourer without tearing off or damaging this strip. The inviolability provided by these known assemblies is not always satisfactory, in particular in the case where the capsule is retained on the pourer, not by screwing or snap-fastening, but simply by the tightening exerted on the pouring spout by an internal skirt. seal formed on the capsule so as to cooperate by forcing with the spout.

La présente invention a pour objet un ensemble verseur et capsule de bouchage offrant une inviolabilité améliorée, sans augmentation du prix de revient de l'ensemble.The present invention relates to a pouring assembly and closure cap offering improved inviolability, without increasing the cost price of the assembly.

Sur l'ensemble verseur et capsule de bouchage conforme à l'invention, la bande de garantie reliée de façon arrachable au verseur s'étend, depuis le verseur, sur toute la hauteur de la capsule et présente, à son extrémité libre, un retour annulaire intérieur qui coiffe le bord extérieur supérieur de la capsule.On the pourer and closure cap assembly in accordance with the invention, the guarantee strip detachably connected to the pourer extends, from the pourer, over the entire height of the capsule and has, at its free end, a return inner ring which covers the upper outer edge of the capsule.

La bande de garantie de l'ensemble conforme à l'invention entoure donc la capsule non seulement sur toute sa hauteur, mais également à l'endroit de son bord supérieur, de sorte qu'il est impossible de saisir la capsule tant que la bande de garantie n'a pas été arrachée.The guarantee strip of the assembly according to the invention therefore surrounds the capsule not only over its entire height, but also at the place of its upper edge, so that it is impossible to grasp the capsule as long as the strip warranty has not been removed.

De préférence, la capsule présente, sur sa face supérieure, un épaulement annulaire contre lequel porte l'extrémité dudit retour intérieur de la bande de garantie.Preferably, the capsule has, on its upper face, an annular shoulder against which bears the end of said interior return of the guarantee strip.

Cela réduit encore les possibilités de violation dans la mesure où le retour intérieur de la bande de garantie ne fait pas saillie sur le dessus de la capsule, de sorte qu'il est impossible, sans détériorer la bande de garantie, d'introduire par exemple un objet effilé entre la capsule et la bande de garantie, à l'endroit du retour intérieur de cette dernière.This further reduces the possibility of violation since the inside return of the guarantee strip does not protrude from the top of the capsule, so that it is impossible, without damaging the guarantee strip, to introduce for example a tapered object between the capsule and the warranty strip, at the location of the latter's internal return.

Pour simplifier la fabrication du verseur et de la bande de garantie d'une seule pièce par moulage, il est avantageux que le retour intérieur de la bande de garantie soit interrompu par des encoches réparties sur le pourtour. Ces encoches procurent au retour intérieur de la bande de garantie une élasticité suffisante pour permettre le démoulage de ce retour par déformation élastique.To simplify the manufacture of the pourer and the guarantee strip in one piece by molding, it is advantageous for the interior return of the guarantee strip to be interrupted by notches distributed around the periphery. These notches provide the internal return of the guarantee strip with sufficient elasticity to allow the demoulding of this return by elastic deformation.

A la fois pour améliorer l'inviolabilité et pour améliorer l'étanchéité aux gaz (pénétration d'air en cas de conditonnement à chaud et échappement de gaz neutre en cas de conditonnement sous atmosphère de gaz neutre) avant l'arrachage de la bande de garantie, le retour intérieur de la bande de garantie peut être soudé à la capsule.Both to improve the inviolability and to improve the gas tightness (air penetration in the case of hot packaging and neutral gas exhaust in the event of packaging in a neutral gas atmosphere) before tearing off the strip of guarantee, the inside return of the guarantee strip can be welded to the capsule.

Toujours pour améliorer l'étanchéité, il est avantageux que la bande de garantie soit reliée au verseur par une ligne de liaison continue sur tout le pourtour et par des ponts de liaison renforcés répartis sur le pourtour.Still to improve sealing, it is advantageous for the guarantee strip to be connected to the pourer by a continuous connection line all around the perimeter and by reinforced connection bridges distributed around the perimeter.

Suivant un mode de réalisation avantageux, l'ensemble conforme à l'invention peut comprendre un film s'étendant sur la face supérieure de la capsule et soudé sur le retour intérieur de la bande de garantie, sur tout le pourtour.According to an advantageous embodiment, the assembly according to the invention may comprise a film extending over the upper face of the capsule and welded to the inside return of the guarantee strip, around the entire periphery.

Un tel film, par exemple en aluminium ou en d'autres matériaux, ralentit encore les échanges gazeux éventuels entre l'intérieur et l'extérieur, augmente la protection aux rayons ultraviolets, ce qui désirable lors du conditionnement de certains produits sensibles, et procure une surprotection, c'est-à-dire une amélioration de l'inviolabilité, recherchée en particulier pour le conditionnement de produits pharmaceutiques.Such a film, for example made of aluminum or other materials, further slows the possible gas exchanges between the interior and the exterior, increases protection against ultraviolet rays, which is desirable when packaging certain sensitive products, and provides overprotection, that is to say an improvement in inviolability, sought in particular for the packaging of pharmaceutical products.

Pour faciliter la réunion, avant la pose de l'ensemble verseur et capsule de bouchage sur un goulot de bouteille, de la capsule, d'une part, et du verseur avec bande de garantie d'autre part, après fabrication séparée de ces deux éléments, il est avantageux que la capsule présente une forme extérieure en cône convergeant depuis la face supérieure vers le bord inférieur de la capsule. Cette forme en cône simplifie l'enfoncement de la capsule à l'intérieur de la bande de garantie depuis le côté du retour intérieur de cette dernière.To facilitate the assembly, before the installation of the pouring and capping cap assembly on a bottle neck, of the cap, on the one hand, and of the pourer with guarantee band, on the other hand, after separate manufacture of these two elements, it is advantageous for the capsule to have an outer conical shape converging from the upper face towards the lower edge of the capsule. This cone shape simplifies the insertion of the capsule inside the guarantee strip from the inside return side of the latter.

Dans le but d'améliorer également l'inviolabilité de l'ensemble verseur et capsule de bouchage au niveau de la liaison du verseur avec le goulot de la bouteille, le verseur comportant au moins un jupe annulaire entourant extérieurement le goulot et munie d'un bourrelet intérieur pour l'accrochage dans une gorge extérieur du goulot, ladite jupe présente un prolongement s'étendant vers le bas au-delà du bourrelet d'accrochage, pour venir porter par son extrémité inférieure sur un épaulement extérieur du goulot. Ledit prolongement présente plusieurs zones d'épaisseur réduite en forme de rainures verticales.In order to also improve the inviolability of the pouring assembly and closure cap at the connection of the pourer with the neck of the bottle, the pourer comprising at least one annular skirt externally surrounding the neck and provided with a inner bead for hooking in an outer groove of the neck, said skirt has an extension extending downwards beyond the hook bead, to come to bear by its lower end on an outer shoulder of the neck. Said extension has several zones of reduced thickness in the form of vertical grooves.

Ainsi, si l'on cherche à enlever de force le verseur du goulot en introduisant par exemple un objet effilé entre ledit épaulement du goulot et l'extrémité inférieure du prolongement de la jupe extérieure du verseur, les zones d'épaisseur réduite, donc frangibles, de ce prolongement se rompent, ce qui indique qu'une violation a eu lieu.Thus, if it is sought to forcibly remove the spout from the neck by introducing, for example, a tapered object between said shoulder of the neck and the lower end of the extension of the outer skirt of the spout, the zones of reduced thickness, therefore frangible , of this extension break, which indicates that a violation has occurred.

Pour faciliter la mise en place de l'ensemble verseur et capsule de bouchage sur le goulot de bouteille, il est avantageux que la jupe extérieure du verseur présente intérieurement, entre lesdites zones d'épaisseur réduite, des rampes entre ledit prolongement et le bourrelet d'accrochage.To facilitate the installation of the pourer and closure cap assembly on the bottle neck, it is advantageous that the outer skirt of the pourer has internally, between said zones of reduced thickness, ramps between said extension and the bead d 'hanging.

En se référant au dessin annexé, on va décrire ci-après plus en détail un mode de réalisation illustratif et non limitatif d'un ensemble verseur et capsule de bouchage conforme à l'invention; sur le dessin :

  • la figure 1 est une coupe suivant I-I de la figure 2 d'un ensemble verseur et capsule de bouchage conforme à l'invention;
  • la figure 2 est une vue en plan de l'ensemble de la figure 1.
Referring to the appended drawing, there will be described below in more detail an illustrative and nonlimiting embodiment of a pouring assembly and closure cap according to the invention; on the drawing :
  • Figure 1 is a section along II of Figure 2 of a pouring assembly and closure cap according to the invention;
  • Figure 2 is a plan view of the assembly of Figure 1.

Tel qu'illustré par les dessins, l'ensemble verseur et capsule de bouchage comprend un verseur 1 et une capsule de bouchage 2, tous deux en matière plastique, par exemple en polyéthylène.As illustrated by the drawings, the pourer and stopper cap assembly comprises a pourer 1 and a stopper cap 2, both made of plastic, for example polyethylene.

Le verseur 1 comprend deux jupes 3 et 4 concentriques, de forme générale cylindrique, à savoir une jupe intérieure 3 sensiblement lisse et une jupe extérieure 4 comportant un bourrelet annulaire intérieur 5, à peu près à mi-hauteur. Le verseur 1 est enfoncé sur le goulot 6 d'une bouteille de manière que la jupe intérieure 3 pénètre à l'intérieur du goulot et que la jupe extérieure 4 entoure extérieurement le goulot, le bourrelet 5 venant s'encliqueter dans une gorge extérieure 7 du goulot.The pourer 1 comprises two concentric skirts 3 and 4, of generally cylindrical shape, namely a substantially smooth inner skirt 3 and an outer skirt 4 comprising an inner annular bead 5, about halfway up. The pourer 1 is pressed onto the neck 6 of a bottle so that the inner skirt 3 penetrates inside the neck and that the outer skirt 4 externally surrounds the neck, the bead 5 snapping into an outer groove 7 bottleneck.

Les deux jupes 3 et 4 sont réunies par une partie annulaire de liaison 8. La jupe intérieure 3 est prolongée vers le haut, au-delà de la partie de liaison 8, sous la forme d'un bec verseur 9 dont le bord annulaire supérieur 10 est recourbé vers l'extérieur.The two skirts 3 and 4 are joined by an annular connecting part 8. The inner skirt 3 is extended upwards, beyond the connecting part 8, in the form of a pouring spout 9 whose upper annular edge 10 is curved outwards.

En dessous du bourrelet d'accrochage 5, la jupe extérieure 4 comporte un prolongement 11 dont l'extrémité inférieure porte contre un épaulement extérieur 12 du goulot 6. Ce prolongement 11 présente plusieurs zones 13 d'épaisseur réduite, réparties sur le pourtour. Les zones 13 d'épaisseur réduite dont une seule est visible sur la partie gauche de la figure 1 se présentent sous la forme de rainures verticales dans la face intérieure du prolongement 11.Below the attachment bead 5, the outer skirt 4 has an extension 11 whose lower end bears against an outer shoulder 12 of the neck 6. This extension 11 has several zones 13 of reduced thickness, distributed around the periphery. The zones 13 of reduced thickness, only one of which is visible on the left-hand side of FIG. 1 are in the form of vertical grooves in the internal face of the extension 11.

On reconnaît par ailleurs, sur la partie droite de la figure 1, que des rampes 14 sont prévues, entre les zones 13 d'épaisseur réduite, sur la face intérieure du prolongement 11, en dessous du bourrelet d'accrochage 5, pour faciliter l'enfoncement du verseur 1 sur le goulot de bouteille 6.It is also recognized, on the right-hand side of FIG. 1, that ramps 14 are provided, between the zones 13 of reduced thickness, on the inner face of the extension 11, below the attachment bead 5, to facilitate the sinking of the pourer 1 on the bottle neck 6.

La capsule 2 est formée d'un fond 15 sur lequel font saillie vers le bas deux jupes 16, 17 concentriques, de forme générale sensiblement cylindrique. La jupe intérieure 16 est destinée à coopérer par forçage avec l'intérieur du bec verseur 9, pour assurer la fermeture étanche de ce dernier.The capsule 2 is formed by a bottom 15 on which two concentric skirts 16, 17 project downwards, of generally substantially cylindrical shape. The inner skirt 16 is intended to cooperate by forcing with the interior of the pouring spout 9, to ensure the sealed closure of the latter.

La jupe extérieure 17 de la capsule 2 sert à la préhension de la capsule 2 et de butée limitant l'enfoncement de la jupe intérieure 16 dans le verseur 9. A cet effet, l'extrémité inférieure de la jupe extérieure 17 porte, lorsque la capsule est enfoncée à fond, sur la partie de liaison 8 des deux jupes 3 et 4 du verseur 1.The outer skirt 17 of the capsule 2 is used for gripping the capsule 2 and a stop limiting the sinking of the inner skirt 16 in the pourer 9. To this end, the lower end of the outer skirt 17 carries, when the capsule is pushed in fully, on the connecting part 8 of the two skirts 3 and 4 of the pourer 1.

La jupe extérieure 17 de la capsule 2 présente intérieurement une forme cylindrique et extérieurement une forme générale en tronc de cône convergeant depuis le fond 15 vers le bord inférieur de la jupe. Tel que cela est visible sur le côté gauche de la figure 1, la jupe 17 est formée d'une partie supérieure 18 épaisse, d'une partie inférieure 19 mince, et d'une partie de raccordement 20 ayant une forme extérieure fortement tronconique. La comparaison'des parties de gauche et de droite de la figure 1 montre que des nervures verticales 21 réparties sur le pourtour raccordent, sur la face extérieure de la jupe 17, les deux parties 18, 19 avec une conicité plus faible que celle de la surface extérieure de la partie intermédiaire 20. Ces nervures 21 qui constituent une sorte de moletage facilitant la préhension de la capsule 2 donnent à cette dernière une forme extérieure générale tronconique.The outer skirt 17 of the capsule 2 has internally a cylindrical shape and externally a general frusto-conical shape converging from the bottom 15 towards the lower edge of the skirt. As can be seen on the left side of FIG. 1, the skirt 17 is formed from a thick upper part 18, from a thin lower part 19, and from a connection part 20 having a strongly frustoconical external shape. The comparison of the left and right parts of FIG. 1 shows that vertical ribs 21 distributed around the periphery connect, on the external face of the skirt 17, the two parts 18, 19 with a smaller taper than that of the outer surface of the intermediate part 20. These ribs 21 which constitute a sort of knurling facilitating the gripping of the capsule 2 give the latter a generally frustoconical outer shape.

Le fond 15 de la capsule 2 porte, sur sa face supérieure faible distance de son bord extérieur, un bourrelet annulaire 22 qui se trouve sensiblement dans le prolongement de la partie 19 de la jupe 17.The bottom 15 of the capsule 2 carries, on its upper face a short distance from its outer edge, an annular bead 22 which is located substantially in the extension of the part 19 of the skirt 17.

Une bande de garantie 23 arrachable est réalisée d'une seule pièce avec le verseur 1. Tel que cela apparaît sur la figure 2, la bande de garantie 23 s'étend sur tout le pourtour de la capsule 2 et présente une zone d'affaiblissement 24 et une patte d'arrachage 25 située d'un côté de la zone d'affaiblissement 24, l'extrémité libre de la patte 25 étant reliée à la bande 23 par un pont de liaison 26 frangible.A removable security strip 23 is produced in one piece with the pourer 1. As shown in FIG. 2, the guarantee strip 23 extends around the entire periphery of the capsule 2 and has a weakening zone 24 and a tear-off tab 25 located on one side of the weakening zone 24, the free end of the tab 25 being connected to the strip 23 by a frangible connecting bridge 26.

La bande 23 est reliée par son bord inférieur au bord extérieur de la partie de liaison 8 du verseur 1 par une mince ligne de liaison 27 périphérique renforcée, en plusieurs endroits répartis sur le pourtour, par des ponts 28 plus épais (voir partie de gauche et partie de droite de la figure 1).The strip 23 is connected by its lower edge to the outer edge of the connecting part 8 of the pourer 1 by a thin peripheral connecting line 27 reinforced, in several places distributed around the periphery, by thicker bridges 28 (see part on the left and right part of figure 1).

La bande de garantie 23 s'étend depuis sa zone de liaison (27, 28) au verseur 1 vers le haut sur toute la hauteur de la capsule 2 et présente, à son extrémité supérieure, un retour intérieur 29 qui coiffe le bord extérieur du fond 15 de la capsule 2, l'extrémité libre du retour intérieur 29 venant porter contre l'épaulement que constitue la nervure annulaire 22 du fond 15 de la capsule 2. La hauteur de la nervure 22 est égale ou supérieure à l'épaisseur de la bande 23 à l'endroit du retour 29. De cette manière, le retour 29 se trouve en retrait par rapport à la face supérieure du bourrelet 22, ou tout au plus à ras de cette face supérieure du bourrelet 22.The guarantee strip 23 extends from its connection zone (27, 28) to the pourer 1 upwards over the entire height of the capsule 2 and has, at its upper end, an inner return 29 which covers the outer edge of the bottom 15 of the capsule 2, the free end of the inner return 29 coming to bear against the shoulder formed by the annular rib 22 of the bottom 15 of the capsule 2. The height of the rib 22 is equal to or greater than the thickness of the strip 23 at the location of the return 29. In this way, the return 29 is set back relative to the upper face of the bead 22, or at most flush with this upper face of the bead 22.

Le retour intérieur 29 de la bande de garantie 23 comporte plusieurs encoches 30 réparties sur le pourtour. Les encoches 30 ont pour but de donner au retour 29 une élasticité suffisante pour permettre une déformation vers l'extérieur du retour 29 lors de l'enfoncement de la capsule 2 sur le verseur 1 muni de la bande de garantie 23. En effet, pendant cet enfoncement, le retour 29 se trouve déformé vers l'extérieur par la jupe extérieure 17, de forme générale extérieure tronconique, le retour 29 se détendant vers l'intérieur pour reprendre la forme visible sur la figure 1, c'està-dire pour coiffer le bord supérieur extérieur de la capsule 2, lorsque cette dernière est enfoncée à fond, l'extrémité inférieure de la jupe 19 de la capsule 2 portant contre la partie de liaison 8 du verseur 1.The internal return 29 of the guarantee strip 23 comprises several notches 30 distributed around the periphery. The notches 30 are intended to give the return 29 sufficient elasticity to allow deformation towards the outside of the return 29 when the capsule 2 is pressed in on the pourer 1 provided with the guarantee strip 23. In fact, during this depression, the return 29 is deformed towards the outside by the external skirt 17, of generally frustoconical external shape, the return 29 expanding inwards to resume the shape visible in FIG. 1, that is to say for cover the upper outer edge of the capsule 2, when the latter is fully pressed, the lower end of the skirt 19 of the capsule 2 bearing against the connecting part 8 of the pourer 1.

On reconnaît enfin sur les figures 1 et 2 que la bande de garantie 23 comporte des nervures extérieures 31 qui prolongent vers le haut les ponts épais 28 reliant la bande 23 au verseur 1.Finally, it can be seen in FIGS. 1 and 2 that the guarantee strip 23 has external ribs 31 which extend upwards the thick bridges 28 connecting the strip 23 to the pourer 1.

Enfin il y a lieu de noter que le verseur 1 comporte à l'intérieur de sa jupe intérieure 3, un réseau de barrettes reliant une tige centrale 32 visible sur la figure 1 au corps inférieur de la jupe 3. Le but de cet agencement est d'une part de régulariser la coulée, par le verseur, du liquide conditionné dans le récipient équipé de l'ensemble verseur et capsule de bouchage, et d'autre part de simplifier le moulage par injection du verseur. L'injection s'effectue en effet par la tige 32 (carotte) et les barrettes constituent des canaux d'alimentation de l'ensemble du moule.Finally, it should be noted that the pourer 1 has inside its internal skirt 3, a network of bars connecting a central rod 32 visible in FIG. 1 to the lower body of the skirt 3. The purpose of this arrangement is on the one hand to regulate the pouring, by the pourer, of the liquid conditioned in the container equipped with the pouring assembly and closure cap, and on the other hand to simplify the injection molding of the pourer. The injection is effected by the rod 32 (carrot) and the bars constitute supply channels for the entire mold.

Pour améliorer l'étanchéité de l'ensemble verseur et capsule de bouchage avant l'arrachage de la bande de garantie, il est possible de relier le retour intérieur 29 de la bande de garantie 23 par soudage, par exemple à l'aide d'un outil chauffé, au bourrelet 22 de la capsule 2.To improve the leaktightness of the pouring and capping capsule assembly before tearing off the guarantee strip, it is possible to connect the internal return 29 of the guarantee strip 23 by welding, for example using a heated tool, to the bead 22 of the capsule 2.

De plus, comme indiqué en tirets sur la figure 1, une feuille 33, par exemple d'aluminium ou de matière plastique, peut être rapportée sur le dessus de la capsule en étant soudée sur le rebord 29.In addition, as indicated in dashes in FIG. 1, a sheet 33, for example of aluminum or plastic, can be attached to the top of the capsule by being welded to the flange 29.

Sur l'ensemble verseur et capsule de bouchage, toute tentative de violation, préalablement à l'arrachage de la bande de garantie, que se soit au niveau de la liaison verseur 1 - goulot de bouteille 6 ou de la liaison capsule 2 - bande de garantie 3, provoque un endommagement décelable à l'oeil nu (rupture de la partie inférieure 11 de la jupe extérieure 4 du verseur 1 à l'endroit des zones d'affaiblissement 13, rupture de la bande de garantie à l'endroit de la zone d'affaiblissement 24).On the pourer and closure cap assembly, any attempted violation, prior to tearing off the guarantee strip, whether at the pouring link 1 - bottle neck 6 or the capsule 2 - sealing strip link warranty 3, causes damage detectable to the naked eye (rupture of the lower part 11 of the outer skirt 4 of the pourer 1 at the location of the weakening zones 13, rupture of the warranty strip at the location of the weakening zone 24).

De plus, l'ensemble verseur et capsule de bouchage conforme à l'invention procure une étanchéité parfaite et empêche en particulier tout passage de gaz (entrée d'air ou sortie de gaz,protecteur), d'où un allongement de la durée de conservation possible du produit conditionné, dans le cas où, en plus deI la liaison étanche entre la bande de garantie et le verseur, une liaison étanche est prévue également entre la bande de garantie et la capsule (par soudage du retour 29 à la capsule 15 et/ou par l'utilisation d'une feuille supplémentaire soudée sur le retour de la bande de garantie).In addition, the pouring and closure cap assembly according to the invention provides perfect sealing and in particular prevents any passage of gas (air inlet or gas outlet, protective), hence an extension of the duration of possible conservation of the packaged product, in the case where, in addition to the sealed connection between the guarantee strip and the pourer, a sealed connection is also provided between the guarantee strip and the capsule (by welding the return 29 to the capsule 15 and / or by the use of an additional sheet welded on the return of the guarantee strip).
