Description

L'invention a trait à un dispositif de bouchage et à un récipient équipé d'un tel dispositif. L'invention a également trait à un procédé de fabrication d'un tel dispositif et à un procédé de bouchage d'un récipient à l'aide d'un tel dispositif.The invention relates to a closure device and to a container equipped with such a device. The invention also relates to a method of manufacturing such a device and to a method of capping a container using such a device.

Dans le domaine du conditionnement de produits alimentaires, il est connu d'équiper une bouteille en matière plastique extrudée ou soufflée d'un opercule pelable soudé par chauffage par induction sur le bord du goulot de la bouteille. Un tel opercule doit être pelé manuellement et jeté lors de la première utilisation du contenu d'une telle bouteille. Cette opération de pelage est relativement délicate et peut être imparfaitement réalisée, notamment par un enfant ou une personne âgée dont les doigts ont perdu de leur agilité. En outre, cette opération impose à l'utilisateur de se rapprocher d'une poubelle pour jeter l'opercule, sauf à laisser celui-ci traîner sur une table.In the field of food product packaging, it is known to equip an extruded or blown plastic bottle with a peelable seal laminated by induction heating on the edge of the neck of the bottle. Such a cover must be peeled manually and discarded during the first use of the contents of such a bottle. This peeling operation is relatively delicate and may be imperfectly performed, especially by a child or a senior whose fingers have lost their agility. In addition, this operation requires the user to approach a trash to throw the lid, except to let it drag on a table.

Il est connu de CH-A-556 274 d'équiper un bouchon d'une nervure interne destinée à retenir en position un disque pourvu d'une feuille d'aluminium. Pour installer le disque dans le bouchon, il est nécessaire de le déformer temporairement. Il en résulte qu'une déformation du disque en sens opposé peut conduire à son extraction involontaire du bouchon, en particulier lors de la première ouverture d'une bouteille. En outre, lors de la mise en place du disque dans le bouchon, il existe un risque d'endommagement de son bord périphérique, ce qui affecte négativement l'étanchéité obtenue. Ainsi, un tel dispositif ne peut pas être considéré comme fiable.It is known from CH-A-556 274 to equip a plug with an internal rib intended to hold a disk provided with an aluminum foil in position. To install the disc in the cap, it is necessary to deform it temporarily. As a result, deformation of the disc in the opposite direction may lead to its involuntary extraction of the plug, in particular during the first opening of a bottle. In addition, when placing the disc in the cap, there is a risk of damage to its peripheral edge, which adversely affects the seal obtained. Thus, such a device can not be considered reliable.

Il en va de même pour les dispositifs connus de US-A-5,346,082, US-A-4,473,163 et US-A-5,984,124.The same applies to the known devices of US-A-5,346,082, US-A-4,473,163 and US-A-5,984,124.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau dispositif de bouchage qui comprend un opercule d'obturation soudé sur un goulot avant la première utilisation d'un récipient, dans lequel il n'est pas nécessaire de peler manuellement l'opercule pour avoir accès au contenu du récipient et dont le fonctionnement est fiable.It is these drawbacks that the invention intends to remedy more particularly by proposing a new closure device which comprises a closure cap welded on a neck before the first use of a container, in which it is not necessary. to manually peel the lid to access the contents of the container and whose operation is reliable.

Dans cet esprit, l'invention concerne un dispositif de bouchage d'un récipient pourvu d'un goulot fileté, ce dispositif comprenant un bouchon apte à obturer ce goulot, un opercule apte à être collé ou scellé sur le bord de ce goulot, un disque d'étanchéité, sur lequel est fixé l'opercule, ce disque faisant saillie radialement à l'extérieur du goulot, et une bague coiffée par le bouchon et pourvue d'un filetage interne apte à coopérer avec le filetage externe du goulot, cette bague étant équipée d'au moins une saillie qui s'étend en direction du disque et qui est apte à exercer sur le disque un effort de poussée, dans un sens d'écartement du disque par rapport au goulot, la saillie précitée s'étendant à partir d'un bord supérieur de la bague, essentiellement selon une direction axiale.With this in mind, the invention relates to a closure device for a container provided with a threaded neck, this device comprising a stopper capable of closing off this neck, a cover able to be glued or sealed on the edge of this neck, a sealing disk, on which is fixed the lid, this disk protruding radially outside the neck, and a ring capped by the cap and provided with an internal thread adapted to cooperate with the external thread of the neck, this ring being provided with at least one protrusion which extends towards the disc and which is able to exert on the disc a thrust force, in a direction of separation of the disc from the neck, the aforementioned projection extending from an upper edge of the ring, essentially in an axial direction.

Grâce à l'invention, une manipulation appropriée de la bague permet d'exercer, grâce à la saillie, une poussée localisée et suffisante pour éloigner le disque du goulot, ce qui permet de désolidariser l'opercule, qui reste solidaire du disque, par rapport au goulot. Ainsi, on peut se dispenser de l'opération fastidieuse de pelage manuel de l'opercule, telle que nécessaire dans l'état de la technique. Si on le souhaite, la désolidarisation de l'opercule par rapport au goulot peut être indiquée par un signal sonore, par exemple de type « clic ». L'orientation particulière de la saillie selon une direction axiale lui permet d'agir efficacement sur le disque.Thanks to the invention, an appropriate manipulation of the ring makes it possible to exert, thanks to the protrusion, a localized thrust and sufficient to move the disc away from the neck, which makes it possible to separate the lid, which remains secured to the disc, by compared to the bottleneck. Thus, one can dispense with the tedious operation of manual peeling of the lid, as necessary in the state of the art. If desired, the separation of the lid from the neck may be indicated by a sound signal, for example of the "click" type. The particular orientation of the projection in an axial direction allows it to act effectively on the disc.

L'invention concerne également un récipient, tel qu'une bouteille en matière plastique, équipé d'un dispositif de bouchage tel que précédemment décrit. Un tel récipient est plus facile à manipuler que des matériels connus, notamment lors de sa première utilisation.The invention also relates to a container, such as a plastic bottle, equipped with a closure device as previously described. Such a container is easier to handle than known materials, especially when first used.

L'invention concerne également un procédé de fabrication d'un dispositif tel que précédemment décrit et, plus spécifiquement, un procédé dans lequel on met en oeuvre des étapes consistant à :

  • a) - fabriquer une bague pourvue d'un filetage interne apte à coopérer avec le filetage externe du goulot ;
  • b) - fabriquer un disque d'étanchéité ;
  • c) - munir la bague, sur sa surface radiale externe, de reliefs ;
  • d) - munir la bague d'au moins une saillie s'étendant, à partir d'un bord de cette bague, essentiellement selon une direction axiale ;
  • e) - fabriquer un capuchon apte à coiffer le goulot et la bague vissée sur ce goulot ;
  • f) - munir ce capuchon, sur sa surface radiale interne, de reliefs ;
  • g) - introduire le disque d'étanchéité dans le capuchon ;
  • h) - introduire la bague dans le capuchon en amenant en prise les reliefs, prévus respectivement sur la surface radiale externe de la bague et sur la surface radiale interne du capuchon, en dirigeant les saillies vers ledit disque et en bloquant ledit disque dans le capuchon grâce à ladite bague.
The invention also relates to a method of manufacturing a device as previously described and, more specifically, to a method in which steps are performed consisting in:
  • a) - manufacture a ring provided with an internal thread adapted to cooperate with the external thread of the neck;
  • b) - manufacture a sealing disc;
  • c) - provide the ring, on its outer radial surface, reliefs;
  • d) - providing the ring with at least one protrusion extending from an edge of this ring substantially in an axial direction;
  • e) - making a cap adapted to cap the neck and the ring screwed on this neck;
  • f) - provide this cap, on its inner radial surface, reliefs;
  • g) - insert the sealing disc into the cap;
  • h) - inserting the ring into the cap by engaging the reliefs provided respectively on the outer radial surface of the ring and on the inner radial surface of the cap, directing the projections toward said disk and blocking said disk in the cap thanks to said ring.

De façon avantageuse, les étape c) et d) sont réalisées en même temps que l'étape a) qui est une étape de moulage de la bague.Advantageously, steps c) and d) are performed at the same time as step a) which is a step of molding the ring.

De même, l'étape f) est avantageusement réalisée en même temps que l'étape e) qui est une étape de moulage du capuchon.Similarly, step f) is advantageously performed at the same time as step e) which is a step of molding the cap.

Selon un aspect avantageux de l'invention, lors des étapes a) à f), la bague, le capuchon, le disque et la saillie sont dimensionnés et positionnés, de telle sorte que la saillie est apte à retirer le disque du goulot, lors du dévissage du dispositif par rapport au goulot.According to an advantageous aspect of the invention, during steps a) to f), the ring, the cap, the disc and the projection are dimensioned and positioned, so that the projection is able to remove the disc from the neck, when unscrewing the device relative to the neck.

L'invention concerne enfin un procédé de bouchage d'un récipient au moyen d'un dispositif fabriqué selon le procédé mentionné ci-dessus, dans lequel on fixe le disque sur le goulot, par exemple par thermo-scellage d'un opercule porté par le disque, après mise en place du dispositif sur le goulot.The invention finally relates to a method of capping a container by means of a device manufactured according to the method mentioned above, in which the disc is fixed on the neck, for example by heat-sealing a lid carried by the disc, after placing the device on the neck.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre, de deux modes de réalisation d'un récipient et d'un dispositif de bouchage conformes à l'invention, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés, dans lesquels :

  • la figure 1 est une vue en perspective, avec arrachement partiel, du goulot d'une bouteille équipée d'un dispositif de bouchage conforme à l'invention ;
  • la figure 2 est une vue en perspective éclatée du dispositif de bouchage de la figure 1 ;
  • la figure 3 est une demi-coupe axiale de principe du goulot d'une bouteille équipé du dispositif de bouchage des figures 1 et 2 ;
  • la figure 4 est une coupe axiale de principe d'un dispositif de bouchage conforme à un second mode de réalisation de l'invention monté sur le goulot d'une bouteille et
  • la figure 5 est une vue analogue à la figure 1 pour le dispositif de la figure 4, le goulot de la bouteille étant également éclaté. On y a indiqué en IV-IV le plan de coupe de la figure 4.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the description which follows, of two embodiments of a container and a closure device according to the invention, given only by way of example and with reference to the accompanying drawings, in which:
  • Figure 1 is a perspective view, partially broken away, of the neck of a bottle equipped with a closure device according to the invention;
  • Figure 2 is an exploded perspective view of the closure device of Figure 1;
  • Figure 3 is an axial half-section of the principle of the neck of a bottle equipped with the closure device of Figures 1 and 2;
  • FIG. 4 is an axial sectional view of a closure device according to a second embodiment of FIG. realization of the invention mounted on the neck of a bottle and
  • Figure 5 is a view similar to Figure 1 for the device of Figure 4, the neck of the bottle being also exploded. IV-IV shows the sectional plan of Figure 4.

La bouteille B représentée aux figures 1 et 3 comprend un goulot 101 pourvu d'un filet externe 111 et d'une partie 112 dont la surface externe 114 est destinée à recevoir en appui un opercule 122 réalisé dans un complexe à base d'aluminium et appartenant à un dispositif de bouchage 102. Cet opercule est collé, sur sensiblement toute sa surface, sur un disque 121 dont le bord périphérique 321 dépasse radialement à l'extérieur de la surface radiale externe 115 du goulot 101, le diamètre D121 du disque 121 étant supérieur au diamètre D115 de la surface 115.The bottle B shown in FIGS. 1 and 3 comprises a neck 101 provided with an external thread 111 and a part 112 whose outer surface 114 is intended to receive a lid 122 made of an aluminum-based complex and belonging to a closure device 102. This operculum is bonded, over substantially its entire surface, to a disk 121 whose peripheral edge 321 protrudes radially outside the outer radial surface 115 of the neck 101, the diameter D 121 of the disc 121 being greater than the diameter D 115 of the surface 115.

Une bague 124 est prévue pour être vissée sur le goulot 101 et est pourvue, à cet effet, d'un filet interne 341 apte à coopérer avec le filet 111. Cette bague est équipée de trois saillies 344, 344' et 344'' qui s'étendent, à partir de son bord 345 le plus proche du disque 121, globalement selon des directions parallèles à l'axe central X-X' du goulot 101. La saillie 344 est définie par une surface 344a globalement parallèle à l'axe X-X' et une surface inclinée 344b formant rampe, ainsi que cela ressort des explications qui suivent. Les autres saillies ont sensiblement la même forme. Les saillies sont régulièrement réparties sur le bord 345.A ring 124 is provided to be screwed onto the neck 101 and is provided, for this purpose, with an internal thread 341 adapted to cooperate with the thread 111. This ring is equipped with three protrusions 344, 344 'and 344' 'which extend, from its edge 345 closest to the disc 121, generally in directions parallel to the central axis XX 'of the neck 101. The projection 344 is defined by a surface 344a generally parallel to the axis XX' and an inclined surface 344b forming a ramp, as is apparent from the explanations that follow. The other projections have substantially the same shape. The projections are regularly distributed on the edge 345.

Un capuchon 125 monobloc en matière plastique est prévu pour être monté sur le goulot 101 en entourant la bague 124. Le fond 351 de ce capuchon est parallèle au disque 121 et se prolonge par une jupe 352 qui entoure la bague 124. En pratique, le disque 121 est disposé au voisinage de la surface interne 353 du fond 351, deux nervures circulaires 351a et 351b permettant d'exercer sur le disque 321 un effort localisé F2 de placage de l'opercule 122 contre le bord 113 du goulot 101.A one-piece plastic cap 125 is provided to be mounted on the neck 101 by surrounding the ring 124. The bottom 351 of this cap is parallel to the disk 121 and is extended by a skirt 352 which surrounds the ring 124. In practice, the disc 121 is disposed in the vicinity of the inner surface 353 of the bottom 351, two 351 has circular ribs 351 and b possible to exert on the disc 321 a localized effort F 2 of the cover plating 122 against the edge 113 of the neck 101.

Par ailleurs, la jupe 352 est pourvue d'une série de dents 354 ménagée sur sa surface radiale interne 355, ces dents étant configurées et positionnées de telle sorte qu'elles peuvent être en prise avec des dents 346 ménagées sur la surface radiale externe 347 de la bague 124. Ainsi, les éléments 124 et 125 sont solidaires en rotation autour de l'axe X-X'.Furthermore, the skirt 352 is provided with a series of teeth 354 formed on its inner radial surface 355, these teeth being configured and positioned so that they can be engaged with teeth 346 formed on the outer radial surface 347. of the ring 124. Thus, the elements 124 and 125 are integral in rotation about the axis X-X '.

La jupe 352 est également pourvue d'un retour 356 prévu pour s'engager dans une gorge annulaire 348 ménagée dans la surface 347, de telle sorte que les éléments 124 et 125 sont également solidaires en translation parallèlement à l'axe X-X'.The skirt 352 is also provided with a return 356 designed to engage an annular groove 348 formed in the surface 347, so that the elements 124 and 125 are also integral in translation parallel to the axis X-X ' .

Une bague d'inviolabilité est constituée par une partie 349 de la bague 124 reliée à sa partie principale par une zone sécable 349a, la partie 349 étant bloquée sur le goulot 101 par une collerette circulaire 116.A tamperproof ring is constituted by a portion 349 of the ring 124 connected to its main portion by a breakable zone 349 a, the portion 349 being locked to the neck 101 by a circular flange 116.

L'opercule 122 est collé sur le bord 112 jusqu'à la première utilisation de la bouteille B.The cover 122 is stuck on the edge 112 until the first use of the bottle B.

Lorsqu'un effort de dévissage est exercé sur le capuchon 125, celui-ci entraîne la bague 124 du fait de la coopération des dents 346 et 354. Ceci a pour effet de déplacer les saillies 344, 344' et 344'' en direction du bord 321 du disque 121, puis d'exercer sur ce bord un effort de poussée F3 suffisant pour séparer l'opercule 122 de la surface 114, puisque la liaison entre les éléments 121 et 122 est permanente. Le caractère incliné de la surface 344b et des surfaces équivalentes confère à l'effort F3 un caractère progressif en fonction de la rotation de la bague 124.When an unscrewing force is exerted on the cap 125, the latter drives the ring 124 due to the cooperation of the teeth 346 and 354. This has the effect of moving the projections 344, 344 'and 344''towards the edge 321 of the disk 121, then to exert on this edge a thrust force F 3 sufficient to separate the cap 122 of the surface 114, since the connection between the elements 121 and 122 is permanent. The inclined nature of the surface 344 b and equivalent surfaces gives the force F 3 a progressive character depending on the rotation of the ring 124.

L'effort de poussée ou de décollement F3 est concentré au voisinage du bord 321 du disque 121, ce qui améliore son efficacité.The thrust force or detachment F 3 is concentrated near the edge 321 of the disk 121, which improves its efficiency.

Le disque 121 conserve une configuration plane, quelle que soit la force de serrage de la bague 124 sur le goulot 101.The disk 121 retains a flat configuration, regardless of the clamping force of the ring 124 on the neck 101.

En particulier, le disque 121 équipé de l'opercule 122 peut être mis en place contre le fond 351 du capuchon 125 sans être déformé car il peut être mis en place avant que la bague 124 ne soit elle-même introduite dans le capuchon 125.In particular, the disk 121 equipped with the cap 122 can be placed against the bottom 351 of the cap 125 without being deformed because it can be put in place before the ring 124 is itself inserted into the cap 125.

Lorsque le disque est soumis à l'effort localisé F3 exercé par les saillies 344, 344' et 344'', il est possible qu'il fléchisse pendant une phase transitoire de décollement de l'opercule 122 par rapport au goulot 101. Pour ce faire, l'espace prévu pour la réception du bord 321 entre la bague 124 et le capuchon 125 doit être suffisamment large et le fait de réaliser l'ensemble 124-125 en deux pièces permet de ménager un tel espace sans difficultés lors des opérations de moulage respectives de ces pièces, ce qui ne serait pas nécessairement le cas si un tel ensemble était moulé en une seule opération. En outre, les pièces 124 et 125 peuvent réalisées dans des couleurs différentes, ce qui permet à un utilisateur de reconnaître immédiatement le type de dispositif de bouchage qu'il a à manipuler.When the disk is subjected to the localized force F 3 exerted by the projections 344, 344 'and 344'', it is possible for it to bend during a transitional phase of detachment of the cap 122 with respect to the neck 101. this, the space provided for the reception of the edge 321 between the ring 124 and the cap 125 must be sufficiently wide and the fact of making the assembly 124-125 in two parts allows to provide such a space without difficulties during operations respective parts, which would not necessarily be the case if such an assembly were molded in a single operation. In addition, the parts 124 and 125 can be made in different colors, which allows a user to immediately recognize the type of closure device he has to handle.

Lorsqu'il convient de reboucher la bouteille B, il suffit de revisser la bague 124, ce qui a pour effet de plaquer le disque 121 contre la partie 112 du goulot 101 par une nouvelle transmission de l'effort F2 entre les nervures 351a et 351b et le disque 121.Where it is appropriate to reseal the bottle B, it is sufficient to screw the collar 124, which has the effect of pressing the disc 121 against the portion 112 of the neck 101 by a new transmission of the force F 2 between the ribs 351 has and 351 b and the disc 121.

En d'autres termes, le dispositif 102 est aussi aisé à utiliser qu'un bouchon classique dépourvu d'opercule, alors qu'il assure une fermeture totalement étanche du récipient qu'il équipe tant qu'il n'a pas été au moins une fois retiré de celui-ci.In other words, the device 102 is as easy to use as a conventional cap without a lid, while it ensures a completely sealed closure of the container that he equips as long as he has not been removed from it at least once.

La fabrication du dispositif de bouchage 102 a lieu en moulant d'une part la bague 124 et d'autre part le capuchon 125 dans leurs configurations représentées à la figure 2. Lors de ces opérations de moulage, on forme les saillies 344, 344' et 344'' et les dents 346 de la bague 124, de même que les dents 354 du capuchon 125.The manufacture of the closure device 102 takes place by molding on the one hand the ring 124 and on the other hand the cap 125 in their configurations shown in Figure 2. During these molding operations, the projections 344, 344 'are formed. and 344 '' and the teeth 346 of the ring 124, as well as the teeth 354 of the cap 125.

Par ailleurs, on fabrique, par moulage, le disque d'étanchéité 121 et on colle l'opercule 122 sur ce disque.In addition, the sealing disc 121 is made by molding, and the cover 122 is bonded to this disc.

On introduit alors le disque d'étanchéité dans le capuchon de telle sorte que le disque 121 vient au voisinage immédiat de la surface interne 353 du fond 351, en appui sur les nervures 351a et 351b. On place le disque dans une position telle que l'opercule 122 est situé sur la face du disque 121 opposé au fond 351.Then introducing the sealing disc in the cap so that the disc 121 comes in close proximity to the inner surface 353 of bottom 351, resting on the ribs 351 a and 351 b. The disc is placed in a position such that the cover 122 is located on the face of the disc 121 opposite the bottom 351.

On met alors en place la bague 124 dans le capuchon 125 en amenant en prise les dents 346 et 354 et en dirigeant les saillies 344, 344' et 344'' vers le disque, ce qui induit un blocage du disque et de l'opercule entre le fond 351 et les saillies 344, 344' et 344''.The ring 124 is then placed in the cap 125 by engaging the teeth 346 and 354 and directing the protrusions 344, 344 'and 344' 'towards the disk, which induces a blocking of the disc and the operculum between the bottom 351 and the projections 344, 344 'and 344' '.

On note que ce mode de fabrication du dispositif 102 n'induit pas de déformation du disque 121 pour sa mise en place, à la différence des procédés de fabrication des dispositifs connus, par exemple de CH-A-556 274.Note that this method of manufacturing the device 102 does not induce deformation of the disk 121 for its implementation, unlike manufacturing processes of known devices, for example CH-A-556 274.

Dans le second mode de réalisation de l'invention représenté aux figures 4 et 5, les éléments analogues à ceux du premier mode de réalisation portent des références identiques.In the second embodiment of the invention shown in Figures 4 and 5, the elements similar to those of the first embodiment bear identical references.

La bouteille B de ce mode de réalisation comprend un goulot 101 pourvu d'un filetage externe 111 sur lequel vient en prise une bague 124 pourvue d'un filetage 341.The bottle B of this embodiment comprises a neck 101 provided with an external thread 111 on which a ring 124 provided with a thread 341 engages.

Cette bague est pourvue de plusieurs saillies, dont une seule est visible aux figures 4 et 5 avec la référence 344 et qui s'étendent globalement à partir d'un bord 345 de la bague 124 selon une direction parallèle à un axe central X-X' du goulot, de la bague et d'un capuchon associé 125.This ring is provided with several projections, only one of which is visible in FIGS. 4 and 5 with the reference 344 and which extend generally from an edge 345 of the ring 124 in a direction parallel to a central axis XX 'of the neck, the ring and an associated cap 125.

La bague 124 a une géométrie quelque peu différente de celle du premier mode de réalisation mais son fonctionnement est analogue.The ring 124 has a geometry somewhat different from that of the first embodiment but its operation is similar.

En particulier, la bague est pourvue de dents 346 aptes à coopérer avec des dents internes 354 de la jupe 352 du capuchon 125, de façon à être entraînées en rotation autour de l'axe X-X' par ce capuchon, ce qui induit un déplacement de la bague 124 à l'opposé du fond de la bouteille B, ceci ayant pour effet d'amener les saillies 344 et équivalentes en appui contre le bord périphérique 321 du disque 121 et de permettre sa désolidarisation par rapport à une partie inclinée 112 du goulot 101.In particular, the ring is provided with teeth 346 adapted to cooperate with internal teeth 354 of the skirt 352 of the cap 125, so as to be rotated about the axis XX 'by this cap, which induces a displacement of the ring 124 opposite the bottom of the bottle B, this having the effect of bringing the protrusions 344 and equivalent in abutment against the peripheral edge 321 of the disc 121 and to allow its separation from an inclined portion 112 of the neck 101.

Comme précédemment, le disque 121 peut être mis en place contre le fond 351 du capuchon 125 avant que la bague 124 ne soit introduite dans ce capuchon.As before, the disc 121 can be placed against the bottom 351 of the cap 125 before the ring 124 is introduced into this cap.

La bague 124 est pourvue d'une collerette radiale externe 348 adaptée pour être reçue dans un épaulement interne 358 de la jupe 352, ce qui assure un positionnement efficace de ces éléments 124 et 125 l'un par rapport à l'autre. On remarque que, lorsque la bouteille B est fermée, la saillie 344 est écartée du disque 121 d'une distance d non nulle, ce qui évite que le bord 321 ne soit déformé localement par les saillies 344 et équivalentes.The ring 124 is provided with an outer radial flange 348 adapted to be received in an internal shoulder 358 of the skirt 352, which ensures an effective positioning of these elements 124 and 125 relative to each other. Note that when the bottle B is closed, the projection 344 is spaced from the disc 121 by a distance d non-zero, which prevents the edge 321 is locally deformed by the projections 344 and the like.

L'assemblage du dispositif 102 de ce mode de réalisation est effectué avec un procédé analogue à celui explicité en référence au premier mode de réalisation.The assembly of the device 102 of this embodiment is performed with a method similar to that explained with reference to the first embodiment.

Quel que soit le mode de réalisation envisagé, le mode de montage du disque 121 dans le capuchon 125 évite les risques d'endommagement du disque, un tel endommagement affectant négativement l'étanchéité du bouchage obtenu. Ceci est important dans la mesure où un bouchage asceptique est souvent recherché.Whatever the embodiment envisaged, the mounting method of the disc 121 in the cap 125 avoids the risk of damaging the disc, such damage negatively affecting the tightness of the closure obtained. This is important since an asceptic plugging is often sought.

L'invention n'est pas limitée aux modes de réalisation décrits qui peuvent être amendés. En particulier, les caractéristiques techniques des deux modes de réalisation représentés peuvent être combinées entre elles.The invention is not limited to the embodiments described which can be amended. In particular, the technical features of the two embodiments shown can be combined with each other.
