According to the invention, the cap comprises a zone (17) which can be broken off from the outer part (9), permitting its opening during unscrewing of the cap (1), ends, on the one hand, in an empty space (18) between the outer part (9) and the skirt (5), which empty space (18) terminates in the downstream direction with respect to the direction of unscrewing of the cap (1) in at least one attachment (19) which cannot be broken during unscrewing of the cap (1) belonging to the said linking means (11), and, on the other hand, in either a breakable zone (20a) or a cut (20b) or an interruption of continuity (20c) of the inner part (10) so that, when the cap (1) is unscrewed, the tamper evidence strip (8) remains attached to the capping part (3). <IMAGE>

Description

L'invention concerne un bouchon à vis en matière plastique comprenant une bague d'inviolabilité à partie interne retournée à l'intérieur ; un emballage comprenant la combinaison d'un tel bouchon et d'un récipient ; un procédé de fabrication d'un tel bouchon ; et un procédé de fabrication d'un tel emballage.The invention relates to a screw cap made of material plastic including a tamper evident ring internal returned inside; a packaging including the combination of such a stopper and a container; a method of manufacturing such a plug; and a method of manufacture of such packaging.

On connaít déjà des bouchons à vis en matière plastique comprenant :

  • une partie de bouchage ayant une paroi transversale d'extrémité, et une jupe attenante à cette paroi et pourvue d'un filetage interne ;
  • des éventuels moyens d'étanchéité rapportés ou intégrés à la partie de bouchage ;
  • et, d'une seule pièce avec la partie de bouchage, une bague d'inviolabilité ayant une partie externe fermée sur elle-même, disposée dans le prolongement de la jupe et reliée à celle-ci par des moyens de liaison circonférentiellement espacés situés entre les bords libres de la partie externe et de la jupe, et directement attenant à son autre bord, le bord aminci d'une partie interne susceptible de pivoter autour de lui par rapport à la partie externe, cette partie interne étant destinée à être retournée à l'intérieur de la bague en étant dirigée vers la paroi transversale d'extrémité en venant interférer avec une saillie d'un récipient auquel est destiné le bouchon.
We already know plastic screw caps comprising:
  • a plugging part having a transverse end wall, and a skirt adjoining this wall and provided with an internal thread;
  • any sealing means added or integrated into the closure part;
  • and, in one piece with the closure part, a tamper-evident ring having an external part closed on itself, arranged in the extension of the skirt and connected to the latter by circumferentially spaced connecting means located between the free edges of the external part and of the skirt, and directly adjacent to its other edge, the thinned edge of an internal part capable of pivoting around it relative to the external part, this internal part being intended to be returned to the inside of the ring being directed towards the transverse end wall while coming to interfere with a projection of a container for which the stopper is intended.

Dans l'état de la technique illustré par les documents US-A-4 613 052, US-A-4 352 436, US-A-4 653 657, les moyens de liaison de la partie externe, donc de la bague d'inviolabilité, à la jupe sont constitués par des ponts frangibles rompus lors du dévissage du bouchon.In the state of the art illustrated by documents US-A-4 613 052, US-A-4 352 436, US-A-4 653 657, the means of connection of the external part, therefore of the tamper-evident ring, to the skirt consist of frangible bridges broken when unscrewing the cap.

Lorsque le bouchon est dévissé, les ponts frangibles sont rompus et la bague est séparée de la partie de bouchage tout en restant enfilée sur le goulot du récipient dont il est difficile de l'enlever étant donné que la partie interne de la bague vient en blocage contre la saillie du récipient.When the cap is unscrewed, the frangible bridges are broken and the ring is separated from the closure part while remaining threaded on the neck from the container which is difficult to remove since the inner part of the ring locks against the projection of the container.

L'invention a pour but un bouchon à vis du type précédemment mentionné dans lequel la bague d'inviolabilité peut être dégagée du goulot du récipient.The object of the invention is a screw cap of the type mentioned above. wherein the tamper-evident ring can be released from the neck of the container.

Il est connu du document WO91/17090 un bouchon tel que défini dans le préambule de la revendication 1.Document WO91 / 17090 is known for a plug as defined in the preamble of claim 1.

L'invention concerne un bouchon 1 destiné à un récipient 2, l'ensemble formant un emballage.The invention relates to a plug 1 intended for a container 2, the assembly forming a package.

Le bouchon 1 est de type à vis et en matière plastique.The plug 1 is of the screw and material type. plastic.

Il comprend d'abord une partie de bouchage 3 ayant une paroi transversale d'extrémité 4, et une jupe 5 attenante à cette paroi 4 et pourvue d'un filetage interne 6.It first comprises a closure part 3 having a transverse end wall 4, and a skirt 5 adjoining this wall 4 and provided with an internal thread 6.

Le bouchon 1 comprend ensuite d'éventuels moyens d'étanchéité 7. Ceux-ci sont soit intégrés à la partie de bouchage 3 (voir figure 1), soit rapportés sur celle-ci (voir figure 4).The plug 1 then comprises possible means 7. These are either integrated into the part of plugging 3 (see Figure 1), or reported thereon (see figure 4).

Le bouchon 1 comprend enfin une bague d'inviolabilité 8 qui vient de fabrication d'une seule pièce avec la partie de bouchage 3.The plug 1 finally comprises a ring inviolability 8 which comes from the manufacture of a single part with plugging part 3.

La bague 8 comprend une partie externe 9 et une partie interne 10.The ring 8 comprises an external part 9 and a internal part 10.

La partie externe 9 est fermée sur elle-même et elle est disposée dans le prolongement de la jupe 5.The external part 9 is closed on itself and it is arranged in the extension of the skirt 5.

La partie externe 9 est reliée à la jupe 5 par des moyens de liaison il circonférentiellement espacés les uns des autres, situés entre les bords libres 12, 13 de la partie externe 9 et de la jupe 5 respectivement.The external part 9 is connected to the skirt 5 by connecting means it circumferentially spaced apart others, located between the free edges 12, 13 of the external part 9 and skirt 5 respectively.

La partie interne 10 est directement attenante à la partie externe 9. A cet effet, la partie interne 10 comprend un bord aminci 14 attenant à l'autre bord 15 de la partie externe 9. La partie externe 9 est donc limitée du côté de la jupe par le bord libre 12 et du côté opposé par l'autre bord 15.Internal part 10 is directly adjacent to the external part 9. For this purpose, the internal part 10 includes a thinned edge 14 adjoining the other edge 15 of the external part 9. The external part 9 is therefore limited from the side of the skirt by the free edge 12 and on the opposite side by the other edge 15.

La partie interne 10 est susceptible de pivoter autour du bord aminci 14 par rapport à la partie externe 9.The internal part 10 is capable of pivoting around the thinned edge 14 relative to the external part 9.

La partie interne 10 est destinée à être retournée à l'intérieur de la bague 8 en étant dirigée vers la paroi transversale 4.The internal part 10 is intended to be returned inside the ring 8, being directed towards the transverse wall 4.

Lorsque le bouchon 1 est monté vissé sur le récipient 2, la partie interne 10 vient interférer avec une saillie 16 du récipient 2 (voir figure 18).When the plug 1 is mounted screwed onto the container 2, the internal part 10 interferes with a projection 16 of container 2 (see Figure 18).

La partie externe 9 comprend une ou plusieurs zones frangibles 17. Celle-ci permet l'ouverture de la partie externe lors du dévissage du bouchon 1.The external part 9 comprises one or more frangible areas 17. This allows the opening of the external part when unscrewing the cap 1.

Une telle zone frangible 17 aboutit en premier lieu dans un espace libre 18 entre la partie externe 9 et la jupe 5. Cet espace vide 18 est borné vers l'aval par au moins une attache non frangible 19 lors du dévissage du bouchon. Une telle attache non frangible 19 appartient aux moyens de liaison 11. Une zone frangible 17 de la partie externe 9 aboutit en second lieu dans soit une zone frangible 20a, soit une coupure 20b, soit une solution de continuité 20c de la partie interne 10.Such a frangible zone 17 ends first place in a free space 18 between the external part 9 and the skirt 5. This empty space 18 is bounded downstream by at minus a non-frangible fastener 19 when unscrewing the plug. Such a non-frangible fastener 19 belongs to the connecting means 11. A frangible zone 17 of the part external 9 secondly ends up in either an area frangible 20a, either a cut 20b, or a solution of continuity 20c of the internal part 10.

Lors du dévissage du bouchon 1, la bande d'inviolabilité 8 reste ainsi associée à la partie de bouchage 3. When unscrewing the plug 1, the strip inviolability 8 thus remains associated with the part of capping 3.

Les termes amont, aval utilisés se réfèrent au sens de dévissage du bouchon.The terms upstream, downstream used refer to direction of unscrewing the cap.

Les termes axial, transversal se réfèrent à l'axe 21 du bouchon.The terms axial, transverse refer to axis 21 of the plug.

On entend par "zone frangible" une zone où la matière plastique peut être rompue par un effort suffisant qui lui est appliqué. Une telle zone frangible peut comprendre un amincissement de la matière plastique. Un tel amincissement peut être constitué par un enfoncement tel qu'une rainure. Une telle rainure peut être réalisée à partir de la face externe (figure 10A) de la face interne (figure 10B) ou des deux faces externe et interne (figure 10C) de la partie externe 9 ou de la partie interne 10."Frangible area" means an area where the plastic material can be broken by sufficient effort applied to it. Such a frangible area can include a thinning of the plastic. Such thinning can be constituted by a depression such than a groove. Such a groove can be made at from the outer face (Figure 10A) from the inner face (figure 10B) or both external and internal faces (figure 10C) of the external part 9 or of the internal part 10.

On entend par "coupure" une zone où il y a rupture de la continuité de la matière plastique sans espace vide substantiel. Un cas typique de rupture est une fente sans enlèvement de matière."Cut" means an area where there is a break continuity of the plastic without empty space substantial. A typical case of rupture is a crack without removal of material.

On entend par "solution de continuité" une zone où il y a rupture de la continuité de la matière plastique avec un espace vide 20d."Continuity solution" means an area where there is a break in the continuity of the plastic with empty space 20d.

Les figures 11A, 11B, 11C illustrent les trois modes de réalisation correspondant pour la partie interne 10. Une zone frangible 20a est représentée sur la figure 11A. Une coupure 20b est représentée sur la figure 11B. Une solution de continuité 20c avec son espace vide 20d est représentée sur la figure 11C. Une zone frangible 17 de la partie externe 9 s'étend, dans les réalisations considérées, dans une direction générale inclinée par rapport à l'axe 21 du bouchon. Cette direction est opposée au sens du filetage 6 ainsi que cela est bien visible sur les figures 1 à 3. Une zone frangible 20a ou une coupure 20c de la partie interne 10 s'étend dans une direction générale inclinée par rapport à l'axe 21 du bouchon 1.Figures 11A, 11B, 11C illustrate the three corresponding embodiments for the internal part 10. A frangible zone 20a is shown in the figure 11A. A cut 20b is shown in Figure 11B. A continuity solution 20c with its empty space 20d is shown in Figure 11C. A frangible zone 17 of the external part 9 extends, in the embodiments considered, in a general direction inclined by relative to the axis 21 of the plug. This direction is opposite in the sense of thread 6 as is clearly visible on Figures 1 to 3. A frangible zone 20a or a cut 20c of the internal part 10 extends in one direction general inclined with respect to the axis 21 of the plug 1.

Dans une première réalisation, cette direction est dans le sens du filetage 6 (voir figure 17A). Cette réalisation correspond au cas où lors de la fabrication du bouchon, lorsque la partie interne 10 vient en prolongation de la partie externe 9, la zone frangible 20a ou la coupure 20b vient elle-même en prolongation de la zone frangible 17.In a first embodiment, this direction is in the direction of thread 6 (see Figure 17A). This realization corresponds to the case where during the manufacture of the plug, when the internal part 10 comes into extension of the external part 9, the frangible zone 20a or the cut 20b itself comes as an extension of the frangible zone 17.

Dans une seconde réalisation, la direction de la zone frangible 20a ou de la coupure 20b est la même que celle de la zone frangible 17 c'est-à-dire opposée au sens du filetage 6. Cette situation se présente lorsque, au moment de la fabrication du bouchon, la zone frangible 20a ou la coupure 20b s'étend dans une direction sensiblement symétrique à celle de la zone frangible 17 par rapport à un plan transversal passant par les bords 14, 15.In a second embodiment, the management of frangible area 20a or the break 20b is the same as that of frangible zone 17, that is to say opposite to the meaning of thread 6. This situation arises when, at at the time of manufacture of the stopper, the frangible zone 20a or the cut 20b extends in a direction substantially symmetrical to that of frangible zone 17 with respect to a transverse plane passing through the edges 14, 15.

La direction générale d'inclinaison de la zone frangible 17, 20a ou de la coupure 20b fait un angle compris entre 30° et 80° avec l'axe 21. Préférentiellement, cet angle est égal ou voisin de 45°.The general tilt direction of the area frangible 17, 20a or cut 20b makes an angle between 30 ° and 80 ° with axis 21. Preferably, this angle is equal to or close to 45 °.

Préférentiellement, l'angle d'inclinaison de la zone frangible 17 et celui de la zone frangible 20a ou de la coupure 20b est le même.Preferably, the angle of inclination of the frangible zone 17 and that of frangible zone 20a or cut 20b is the same.

Une zone frangible 17 s'étend du bord 12 au bord 15 opposé. Une zone frangible 20a ou une coupure 20b ou une solution de continuité 20c s'étend du bord aminci 14 au bord libre 22 de la partie interne 10.A frangible zone 17 extends from edge 12 to edge 15 opposite. A frangible zone 20a or a cut 20b or a continuity solution 20c extends from the thinned edge 14 to free edge 22 of the internal part 10.

Une zone frangible 17, 20a ou une coupure 20b s'étend essentiellement le long d'une direction rectiligne.A frangible zone 17, 20a or a cut 20b essentially extends along a straight direction.

Dans la réalisation de la figure 12, la zone frangible 17 aboutit dans l'espace vide 18 de façon sensiblement orthogonale à l'axe 21. Il s'ensuit que la zone frangible 17 vient prolonger sensiblement l'espace vide 18, ce qui est de nature à favoriser la rupture la zone frangible 17.In the embodiment of Figure 12, the area frangible 17 ends up in empty space 18 so substantially orthogonal to axis 21. It follows that the frangible zone 17 substantially extends the space vacuum 18, which is likely to favor the rupture the frangible area 17.

Dans cette réalisation et dans le cas où la zone frangible 17 s'étend essentiellement le long d'une direction rectiligne inclinée par rapport à l'axe 21, il est prévu que la zone frangible 17 se termine, du côté du bord 12 par un tronçon incurvé 23.In this realization and in case the area frangible 17 extends essentially along a rectilinear direction inclined with respect to the axis 21, it the frangible zone 17 is expected to end, on the side of the edge 12 by a curved section 23.

Dans la réalisation de la figure 13, une zone frangible 17 de la partie externe 9 présente un tronçon 24 orthogonal à l'axe 21 du bouchon. Ce tronçon orthogonal 24 est interposé entre deux tronçons 24a, 24b inclinés par rapport à l'axe 21. Cette disposition permet une transmission des forces dans le sens de l'axe 21.In the embodiment of FIG. 13, an area frangible 17 of the external part 9 has a section 24 orthogonal to axis 21 of the plug. This orthogonal section 24 is interposed between two sections 24a, 24b inclined by relative to axis 21. This arrangement allows a transmission of forces in the direction of axis 21.

Dans une autre réalisation non représentée, la zone frangible 17 comporte plusieurs tronçons 24.In another embodiment not shown, the area frangible 17 comprises several sections 24.

Une attache non frangible 19 jouxte immédiatement la partie extrême d'une zone frangible 17 de la partie externe 9 aboutissant au bord libre 12 de celle-ci. Lors du dévissage du bouchon 1, l'espace vide 18 tend à être élargi. Lorsque l'on arrive à l'endroit d'une attache non frangible 19 qui ne peut être rompue par simple dévissage du bouchon 1, les forces axiales s'appliquent immédiatement à la zone frangible 17 puisque celle-ci est attenante à l'attache non frangible 19. L'attache non frangible 19 contribue à transférer les forces de rupture découlant du bouchon 1 à la zone frangible 17.A non-frangible fastener 19 immediately adjoins the extreme part of a frangible area 17 of the part outer 9 leading to the free edge 12 thereof. During the unscrewing the plug 1, the empty space 18 tends to be expanded. When you reach the place of a non-fastening frangible 19 which cannot be broken by simply unscrewing plug 1, axial forces apply immediately to frangible zone 17 since this adjoins the non-frangible tie 19. The non-frangible tie 19 helps to transfer the breaking forces arising from the plug 1 at frangible area 17.

Si une attache non frangible 19 n'est pas rompue lors du dévissage du bouchon 1, elle peut être d'une tenue insuffisante de manière que, après dévissage du bouchon, elle puisse être rompue par un effort de traction suffisant exercé par l'utilisateur.If a non-frangible tie 19 is not broken when unscrewing the cap 1, it can be held insufficient so that, after unscrewing the cap, it can be broken by sufficient tensile force exercised by the user.

Dans cette réalisation, le bouchon une fois débouché comporte, attenant à la partie de bouchage 3, la bague d'inviolabilité 8. L'utilisateur peut alors séparer la bague d'inviolabilité 8 de la partie de bouchage 3. Non seulement le récipient 2 sera alors dépourvu de bague 8 restant enfilée autour de son goulot, mais encore la bague 8 sera séparée de la partie de bouchage 3.In this embodiment, the cap once outlet has, adjacent to the plugging part 3, the tamper-evident ring 8. The user can then separate the tamper-evident ring 8 of the closure part 3. No only the container 2 will then have no ring 8 remaining threaded around its neck, but still the ring 8 will be separated from the plugging part 3.

Une solution de continuité 20c de la partie interne 10 constituée par l'espace vide 20d s'étend circonférentiellement autour de l'axe 21. L'ouverture de l'arc de cet espace vide est compris entre 20° et 100° et préférentiellement entre 30° et 90°. Cet arc a une ouverture correspondant sensiblement à celle de l'attache non frangible 19 disposée en regard. Dans la réalisation de la figure 7, les deux bords limites d'une solution de continuité 20c de la partie interne 10 sont disposés dans des plans sensiblement axiaux du bouchon 1. Dans la variante de réalisation de la figure 2, ces bords sont placés de façon divergente depuis le bord aminci 14 jusqu'au bord libre 22. A 20c continuity solution for the internal part 10 constituted by the empty space 20d extends circumferentially around the axis 21. The opening of the arc of this empty space is between 20 ° and 100 ° and preferably between 30 ° and 90 °. This bow has a opening corresponding substantially to that of the fastener non frangible 19 arranged opposite. In the realization of Figure 7, the two boundary edges of a solution of continuity 20c of the internal part 10 are arranged in substantially axial planes of the plug 1. In the variant of FIG. 2, these edges are diverging from the thinned edge 14 to the free edge 22.

Les bords limites d'une solution de continuité 20c de la partie interne 10 sont inclinés avec un angle égal ou de l'ordre de 45° sur l'axe 21 du bouchon 1.The boundary edges of a 20c continuity solution of the internal part 10 are inclined at an equal angle or of the order of 45 ° on the axis 21 of the plug 1.

La partie externe 9 a une épaisseur sensiblement constante sur toute sa périphérie et sa hauteur axiale à l'exception de la ou des zone(s) frangible(s) 17 qu'elle comporte. Cette épaisseur est au plus sensiblement égale, ou éventuellement inférieure, à celle de la jupe 5. Cette dernière comporte préférentiellement des godrons disposés axialement favorisant la tenue de la partie de bouchage 3 dans les doigts de l'utilisateur et empêchant le glissement relatif.The external part 9 has a thickness which is substantially constant over its entire periphery and its axial height at the exception of frangible area (s) 17 that it behaves. This thickness is at most substantially equal, or possibly lower, than that of skirt 5. This last preferably comprises gadroons arranged axially favoring the holding of the plugging part 3 in the user's fingers and preventing slipping relative.

Dans la réalisation des figures 1, 4 et 6, la partie interne 10 s'étend sur une hauteur axiale qui est au plus égale à la hauteur axiale de la partie externe 9. La partie externe 9 recouvre alors totalement la partie interne 10. En particulier, la partie interne 10 s'étend sur environ la moitié de la hauteur axiale de celle de la partie externe 9 (voir figure 4).In the embodiment of Figures 1, 4 and 6, the internal part 10 extends over an axial height which is at more equal to the axial height of the external part 9. The external part 9 then completely covers the part internal 10. In particular, the internal part 10 extends about half the axial height of that of the external part 9 (see figure 4).

Dans une autre variante de réalisation (figure 14), la partie interne 10 s'étend sur une hauteur axiale supérieure à celle de la partie externe 9. La partie externe 9 ne recouvre alors que partiellement la partie interne 10 qui est partiellement située au droit de la jupe 5 vers son bord libre 13.In another alternative embodiment (FIG. 14), the internal part 10 extends over an axial height greater than that of the external part 9. The part external 9 only partially covers the part internal 10 which is partially located to the right of the skirt 5 towards its free edge 13.

Dans les réalisations représentées, la partie interne 10 a, en section droite axiale, une forme générale triangulaire ou trapézoïdale avec un sommet défini par le bord aminci 14 et une base opposée définie par le bord libre 22 épaissi. L'épaisseur de la partie interne 10 va alors en croissant régulièrement du bord 14 au bord libre opposé 22.In the realizations represented, the part internal 10 has, in axial cross section, a general shape triangular or trapezoidal with a vertex defined by the thinned edge 14 and an opposite base defined by the edge free 22 thickened. The thickness of the internal part 10 goes then increasing steadily from edge 14 to free edge opposite 22.

Dans une première modalité de réalisation de l'invention, les moyens de liaison 11 sont constitués par les seules attaches non frangibles 19. Dans ce cas, il est prévu au moins deux zones frangibles 17 de la partie externe 9 et deux zones frangibles 20a de la partie interne 10. La partie interne 10 est ainsi pourvue de zones frangibles 20a plutôt que de coupures 20b ou de solution de continuité 20c de manière que la partie interne 10 constitue un anneau fermé sur lui-même contribuant à la tenue de la partie externe 9.In a first embodiment of the invention, the connecting means 11 are constituted by the only non-frangible fasteners 19. In this case, it is provided at least two frangible areas 17 of the part outer 9 and two frangible zones 20a of the inner part 10. The internal part 10 is thus provided with zones frangibles 20a rather than cuts 20b or solution of continuity 20c so that the internal part 10 constitutes a ring closed on itself contributing to the holding of the external part 9.

Dans un autre mode d'exécution de l'invention, les moyens de liaison 11 sont constitués par les attaches non frangibles 19 et également par des ponts frangibles 26 circonférentiellement espacés les uns des autres, rompus lors du dévissage du bouchon.In another embodiment of the invention, the connecting means 11 are formed by the fasteners not frangible 19 and also by frangible bridges 26 circumferentially spaced from each other, broken when unscrewing the cap.

Les variantes des figures 1 à 8 correspondent au cas où les moyens de liaisons 11 comprennent des attaches non frangibles 19 et des ponts frangibles 26. La variante de la figure 9 correspond au cas où les moyens de liaison 11 ne comprennent que des attaches non frangibles 19. Aucun pont frangible tel que 26 n'étant alors prévu.The variants of Figures 1 to 8 correspond to case where the connecting means 11 comprise fasteners non-frangible 19 and frangible bridges 26. The variant of Figure 9 corresponds to the case where the connecting means 11 include only non-frangible fasteners 19. None frangible bridge such as 26 then being provided.

On se réfère maintenant plus spécialement aux figures 5 et 15.We now refer more specifically to Figures 5 and 15.

Un pont frangible 26 a, en section droite transversale, une forme générale triangulaire avec une base attenante à la face interne de la jupe 5 et de la partie externe 9 et un sommet opposé vers l'extérieur. La disposition de ce pont est telle que le démoulage du bouchon est rendu possible. Le sommet du pont frangible 26 et disposé légèrement en retrait par rapport à la face externe de la jupe 5 et de la partie externe 9. En élévation axiale, un pont frangible 26 a une forme générale triangulaire ou trapézoïdale avec un grand côté attenant à la partie externe 9 ou un sommet ou un petit côté attenant à la jupe 5.A frangible bridge 26 a, in cross section transverse, a general triangular shape with a base adjoining the internal face of the skirt 5 and the part external 9 and a vertex opposite towards the outside. The arrangement of this bridge is such that the release of the plug is made possible. The top of frangible bridge 26 and placed slightly behind the face outer of the skirt 5 and the outer part 9. In axial elevation, a frangible bridge 26 has a general shape triangular or trapezoidal with a large side adjoining the external part 9 or an apex or a small adjoining side at the skirt 5.

Dans une réalisation possible, un pont frangible 26 s'étend dans une direction générale inclinée par rapport à l'axe du bouchon (voir le pont frangible de droite sur la figure 15). Cette direction générale est inclinée dans le même sens que le filetage 6.In one possible embodiment, a frangible bridge 26 extends in a general direction inclined to the axis of the plug (see the right frangible bridge on the figure 15). This general direction is inclined in the same direction as thread 6.

Le bouchon selon l'invention comprend, lorsqu'il est prévu des ponts frangibles 26, le minimum de ponts. Ce nombre minimum est de l'ordre de quatre, cinq ou six.The stopper according to the invention comprises, when Frangible bridges 26 are provided, the minimum of bridges. This minimum number is around four, five or six.

Une attache non frangible 19 est éloignée du premier pont frangible 26 situé vers l'amont d'un arc dont l'ouverture est comprise entre 45° et 90°.A non-frangible fastener 19 is distant from the first frangible bridge 26 located upstream of an arc whose the opening is between 45 ° and 90 °.

Une attache non frangible 19 peut également avoir pour fonction d'assurer une solidarisation en rotation de la bague 8 par rapport à la partie de bouchage 3.A non-frangible tie 19 can also have for the function of securing in rotation of the ring 8 relative to the plugging part 3.

Selon une autre caractéristique, le bouchon comporte également au moins un appui axial sous la forme d'une saillie de la jupe 5 et/ou de la partie externe 10, prolongeant celle-ci à partir de son bord libre 13, 12 en direction de celle-là. Une telle saillie est située dans l'espace vide 18. Elle a pour effet d'éviter l'écrasement de l'espace vide 18 lors du montage du bouchon 1 sur le récipient 2. Un tel appui 27 se présente comme circonférentiellement étendu sur un arc dont l'ouverture est inférieur à 40° environ. Deux appuis adjacents sont séparés l'un de l'autre par au moins un pont frangible 26 ou une attache non frangible 19. Deux appuis 27 adjacents sont séparés l'un de l'autre par au plus quatre ponts frangibles 26. Une attache non frangible 19 est éloignée du premier pont frangible 26 par un appui 27. Un appui 27 attenant à la jupe 5 a une épaisseur radiale sensiblement égale à celle de la jupe 5 et présentent des bords axiaux arrondis (voir figure 5). Des appuis 27 occupent de l'ordre du tiers à la moitié de la circonférence de l'espace vide 18. Différents types d'appuis sont illustrés sur la figure 16. Le premier appui à gauche vient prolonger la jupe 5. Le deuxième appui vient prolonger la partie externe 9. Le troisième appui est réalisé à partir d'une prolongation de la jupe 5 et d'une prolongation de la partie externe 9. Enfin, le quatrième et dernier appui est du même type que le précédent, chacune des deux parties venant dépasser l'autre de manière à permettre un blocage en rotation. Une attache non frangible 19 est située sensiblement diamétralement opposée à une autre attache non frangible 19 ou à un pont frangible 26.According to another characteristic, the stopper also includes at least one axial support in the form a projection of the skirt 5 and / or of the external part 10, extending it from its free edge 13, 12 in direction of that one. Such a projection is located in empty space 18. It has the effect of preventing overwriting of the empty space 18 when mounting the plug 1 on the container 2. Such a support 27 appears as circumferentially extended on an arc whose opening is less than about 40 °. Two adjacent supports are separated from each other by at least one frangible bridge 26 or a non-frangible tie 19. Two adjacent supports 27 are separated from each other by up to four bridges frangible 26. A non-frangible fastener 19 is distant from the first frangible bridge 26 by a support 27. A support 27 adjoining the skirt 5 has a substantially radial thickness equal to that of skirt 5 and have axial edges rounded (see Figure 5). Supports 27 occupy order from one third to half the circumference of the empty space 18. Different types of supports are illustrated in the figure 16. The first press on the left extends skirt 5. The second press extends the external part 9. The third press is carried out from an extension of the skirt 5 and an extension of the external part 9. Finally, the fourth and last press is of the same type as the previous one, each of the two parts coming beyond the other so as to allow a rotation lock. A non-frangible fastener 19 is located substantially diametrically opposite to another non-frangible fastener 19 or a frangible bridge 26.

On se réfère maintenant aux figures 1, 4, 6 et 18 qui montrent une partie interne 10 inclinée par rapport à la partie externe 9 avec un angle de l'ordre de 10° à 60°, plus spécialement de l'ordre de 20° à 40° et notamment égale ou de l'ordre de 30°. Cet angle est tel que le dévissage du bouchon 1 sollicite la partie interne 10 à pivotement de son bord aminci 14 dans le sens tendant à l'écarter. La partie interne 10 a un bord libre 22 écarté radialement de la partie externe 9 ou de la jupe 5. We now refer to Figures 1, 4, 6 and 18 which show an internal part 10 inclined with respect to the external part 9 with an angle of the order of 10 ° to 60 °, more especially of the order of 20 ° to 40 ° and in particular equal or about 30 °. This angle is such that the unscrewing the plug 1 urges the internal part 10 to pivoting of its thinned edge 14 in the direction tending to dismiss it. The internal part 10 has a free edge 22 apart radially from the external part 9 or from the skirt 5.

La partie interne 10 est, lorsque le bouchon 1 est monté sur le récipient 2, disposée sensiblement de la même manière que sur le bouchon 1 avant montage, une fois la partie 10 retournée à l'intérieur de la bague 8. Le jeu existe entre la partie interne 10 et la partie externe 9 où la jupe 5 permet de rattraper les écarts dimensionnels tendant aux tolérances notamment sur le récipient 2. Ce rattrapage de jeu est rendu possible d'autant plus que le blocage de la partie interne 10 sur la saillie 16, s'effectue vers l'intérieur c'est-à-dire en direction de l'axe 21 et non vers l'extérieur en direction de la partie externe 9.The internal part 10 is, when the plug 1 is mounted on container 2, arranged substantially the same so that on the plug 1 before mounting, once the part 10 turned inside the ring 8. The game exists between the internal part 10 and the external part 9 where the skirt 5 makes it possible to make up for dimensional differences tending to tolerances especially on container 2. This game catching up is made possible especially since the blocking of the internal part 10 on the projection 16, takes place inward, i.e. towards axis 21 and not outwards towards the part external 9.

On se réfère maintenant plus spécialement aux figures 1 à 3 qui illustrent une première variante de réalisation.We now refer more specifically to Figures 1 to 3 which illustrate a first variant of production.

Dans cette variante, le bouchon 1 comprend une attache non frangible 19 unique et une solution de continuité 20c de la partie interne 10 également unique. Dans d'autres réalisations de la même variante, il peut être substitué à la solution de continuité 20c une zone frangible 20a ou une coupure 20b. Dans l'exemple illustré sur les dessins, il est prévu quatre ponts frangibles 26 répartis de façon sensiblement régulière sur une moitié de la périphérie du bouchon 1 à l'opposé de la zone frangible 17 de la partie externe 9 et de la solution de continuité 20c de la partie interne 10. De plus, il est prévu trois appuis 27 dont deux sont sensiblement diamétralement opposés l'un à l'autre et le troisième diamétralement opposé à l'attache non frangible 19. Ainsi, en remontant vers l'amont, à partir de la zone frangible 17, on rencontre successivement un premier appui 27, un premier pont puis un deuxième pont frangible 26, un deuxième appui 27, un troisième pont 26, un troisième appui 27, un troisième et dernier appui 27, un quatrième et dernier pont 26 et, enfin, trois attaches non frangibles 19. Dans cette réalisation, la partie interne 10 se présente sous la forme d'un anneau ouvert ou fermé mais en un seul tenant.In this variant, the plug 1 comprises a single non-frangible fastener 19 and a solution of continuity 20c of the internal part 10 also unique. In other embodiments of the same variant, it can be substituted for the 20c continuity solution an area frangible 20a or a cut 20b. In the illustrated example in the drawings, four frangible bridges are provided 26 distributed approximately evenly over half of the periphery of the plug 1 opposite the frangible zone 17 of the external part 9 and of the continuity solution 20c of the internal part 10. In addition, there are three supports 27 of which two are substantially diametrically opposite each other and the third diametrically opposite the non-frangible fastener 19. Thus, going up upstream, from frangible zone 17, we successively meets a first support 27, a first bridge then a second frangible bridge 26, a second support 27, a third bridge 26, a third support 27, a third and last support 27, a fourth and last bridge 26 and, finally, three non-frangible fasteners 19. In this embodiment, the internal part 10 is in the form an open or closed ring but in one piece.

On se réfère maintenant plus spécialement aux figures 4 et 5 qui illustrent une deuxième variante de réalisation.We now refer more specifically to Figures 4 and 5 which illustrate a second variant of production.

Dans cette deuxième variante, il est prévu deux attaches non frangibles 19, sensiblement diamétralement opposées l'une à l'autre ainsi que deux solutions de continuité 20c de la partie interne 10 également sensiblement diamétralement opposée l'une à l'autre. Comme précédemment, il peut être substitué à des solutions de continuité 20c, des zones frangibles 20a ou des coupures 20b.In this second variant, two non-frangible fasteners 19, substantially diametrically opposite each other as well as two solutions of continuity 20c of the internal part 10 also substantially diametrically opposed to each other. As previously, it can be substituted for solutions of continuity 20c, frangible areas 20a or cuts 20b.

Dans cette variante, il existe six ponts frangibles 26 sensiblement diamétralement opposés les uns aux autres, situés dans la partie médiane de la partie externe 9. Il est prévu de plus quatre appuis 27, deux à deux opposés, séparés soit par des ponts frangibles 26, soit par des attaches non frangibles 19. Ainsi, en tournant autour de l'axe 21 vers l'amont en partant d'une zone frangible 17, on rencontre successivement un premier appui 27, un premier puis un deuxième puis un troisième pont frangible 26, un deuxième appui 27, une attache non frangible 19, une zone frangible 17, un troisième appui 27, un quatrième puis un cinquième puis un sixième pont frangible 26, un quatrième et dernier appui 27 et, enfin, la seconde attache non frangible 19. In this variant, there are six frangible bridges 26 substantially diametrically opposed to each other, located in the middle part of the external part 9. It is also provided four supports 27, two opposite two, separated either by frangible bridges 26 or by non-frangible fasteners 19. So, turning around the axis 21 upstream from a frangible zone 17, there is successively a first support 27, a first then a second then a third frangible bridge 26, a second support 27, a non-frangible fastener 19, a zone frangible 17, a third support 27, a fourth then a fifth then a sixth frangible bridge 26, a fourth and last support 27 and, finally, the second attachment not frangible 19.

On se réfère maintenant plus spécialement aux figures 6, 7 et 8 qui illustrent une troisième variante de réalisation.We now refer more specifically to Figures 6, 7 and 8 which illustrate a third variant of production.

Dans cette variante, il est prévu trois attaches non frangibles 19 disposées sensiblement à 120° l'une de l'autre et trois solutions de continuité 20c de la partie interne 10 également sensiblement disposées à 120° l'une de l'autre. Dans cette réalisation, il y a six ponts frangibles 26, disposés sensiblement à 120° l'un de l'autre situés sensiblement dans la partie médiane des éléments de la partie interne 10 séparés par les solutions de continuité et diamétralement opposés aux attaches non frangibles 19. Egalement, il est prévu six appuis 27 sensiblement à 120° l'un de l'autre. En tournant autour de l'axe 21 vers l'amont à partir d'une première zone frangible 17, on rencontre successivement un premier appui 27, un premier et un deuxième pont frangible 26, un deuxième appui 27, une attache non frangible 19, une deuxième zone frangible 17, un quatrième appui 27, un troisième puis un quatrième pont frangible 26, un quatrième appui 27, une attache non frangible 19, la troisième et dernière zone frangible 17, un cinquième puis un sixième dernier pont frangible 26, un sixième et dernier appui 27 et, enfin, une troisième attache non frangible 19.In this variant, three fasteners are provided non-frangible 19 arranged substantially at 120 ° one of the other and three 20c continuity solutions of the part internal 10 also substantially arranged at 120 ° one of the other. In this realization, there are six bridges frangible 26, arranged substantially at 120 ° from one another located substantially in the middle part of the elements of the internal part 10 separated by the solutions of continuity and diametrically opposed to the fasteners not frangibles 19. Also, six supports are provided 27 approximately 120 ° from each other. Turning around axis 21 upstream from a first zone frangible 17, there is successively a first support 27, a first and a second frangible bridge 26, a second support 27, a non-frangible fastener 19, a second frangible zone 17, a fourth support 27, a third then a fourth frangible bridge 26, a fourth support 27, a non-frangible fastener 19, the third and last frangible zone 17, a fifth then a sixth last frangible bridge 26, a sixth and last support 27 and, finally, a third non-frangible fastener 19.

On se réfère maintenant plus spécialement à la figure 9 qui illustre une quatrième variante de réalisation. Dans cette variante de réalisation, il est prévu quatre attaches non frangibles 19 sensiblement écartées l'une de l'autre d'un quart de tour. Dans le cas de la variante illustrée par le dessin, les attaches non frangibles 19 constituent à elles seules les moyens de liaison 11, le bouchon 1 étant dépourvu de ponts frangibles 26. La partie interne 10 comprend alors quatre zones frangibles 20a sensiblement écartées l'une de l'autre d'un quart de tour.We now refer more specifically to the Figure 9 which illustrates a fourth variant of production. In this alternative embodiment, it is provided four non-frangible fasteners 19 substantially separated from each other by a quarter turn. In the case of the variant illustrated by the drawing, the fasteners not frangibles 19 alone constitute the means of connection 11, the plug 1 being devoid of frangible bridges 26. The internal part 10 then comprises four zones frangibles 20a substantially separated from each other by a quarter turn.

Dans une réalisation non représenté, il est prévu quatre ponts frangibles 26 et quatre zones frangibles 20a ou coupure 20b ou solution de continuité 20c de la partie interne 10 sensiblement écartés l'un de l'autre d'un quart de tour.In an embodiment not shown, provision is made four frangible bridges 26 and four frangible zones 20a or cut 20b or continuity solution 20c of the part internal 10 noticeably separated from each other by a quarter of turn.

Selon l'invention, la partie interne 10 est limitée par le bord libre 22 qui se trouve dans un ou plusieurs plans P qui peuvent être inclinés par rapport à un plan de référence R orthogonal à l'axe 21 du bouchon.According to the invention, the internal part 10 is limited by the free edge 22 which is in one or more P planes which can be tilted with respect to a plane of reference R orthogonal to axis 21 of the cap.

Le plan R est par exemple le plan défini par le bord 15 de la partie externe 9.The plane R is for example the plane defined by the edge 15 of the external part 9.

Dans une cinqième et une sixième variante de réalisation, le bord libre 22 se trouve tout entier sensiblement dans un seul et même plan (voir figures 19 et 20). Dans une septième variante, le bord libre 22 se trouve situé dans plusieurs plans P (voir figure 21). Dans ce dernier cas, la partie interne 10 peut présenter des sortes d'indentations plus ou moins accentuées et en nombres plus ou moins importants. Dans la cinqième variante réalisée figure 19, le plan P est incliné dans le sens du filetage 6 du bouchon, dans la sixième variante de la figure 20, le plan P est incliné dans le sens opposé du filetage 6 du bouchon. In a fifth and a sixth variant of realization, the free edge 22 is entirely substantially in a single plane (see Figures 19 and 20). In a seventh variant, the free edge 22 is located in several planes P (see Figure 21). In this last case, the internal part 10 can present sorts more or less accentuated indentations and more or less important. In the fifth variant carried out Figure 19, the plane P is inclined in the direction of the thread 6 of the plug, in the sixth variant of FIG. 20, the plane P is inclined in the opposite direction of thread 6 of the plug.

Le plan P est incliné par rapport au plan R avec un angle compris entre 0 et 10° environ et préférentiellement de l'ordre de 3 à 4°.The plane P is inclined with respect to the plane R with a angle between 0 and 10 ° approximately and preferably on the order of 3 to 4 °.

Selon l'invention (figures 20 et 21), la zone frangible 17 est située en regard ou au voisinage du regard d'une localisation de la partie interne 10 ou celle-ci est de plus grande longueur axiale. Cette localisation correspond à un "point haut" 30 du bord libre 22 se trouvant le plus loin des bords 14 et 15 et le plus près de la paroi transversale d'extrémité 4.According to the invention (Figures 20 and 21), the area frangible 17 is located opposite or in the vicinity of the gaze of a location of the internal part 10 or this is of greater axial length. This location corresponds to a "high point" 30 of the free edge 22 finding furthest from edges 14 and 15 and closest to the transverse end wall 4.

Dans le cas le plus général, il existe aussi pour le bord libre 22 un "point bas" 31 le plus près des bords 14 et 15 et le plus loin de la paroi 4.In the most general case, it also exists for the free edge 22 a "low point" 31 closest to the edges 14 and 15 and farthest from the wall 4.

Si le point haut 30 est préférentiellement proche d'une zone frangible 17, inversement, une zone frangible 20a ou une coupure 20b ou une solution de continuité 20c de la partie interne 10 est située en regard ou au voisinage du regard d'une localisation de la partie interne 10 où celle-ci est de plus petite longueur axiale c'est-à-dire en regard ou au voisinage du point bas 31.If the high point 30 is preferably close a frangible zone 17, conversely, a frangible zone 20a or a cut 20b or a continuity solution 20c of the internal part 10 is located opposite or in the vicinity from the look of a location of the internal part 10 where this is of smaller axial length, that is to say in look or near the low point 31.

Le plan P peut avoir, par rapport au plan transversal de référence R1 défini par le bord 15 trois positions différentes :

  • soit le plan P coupe le plan R1 le long d'une ligne sensiblement tangente à la partie externe 9. (figure 22) Dans ce cas, cela définit pour la partie interne 10 une une solution de de continuité 20c au point bas 31.
  • soit le plan P coupe le plan R1 à l'intérieur même du bouchon c'est-à-dire de façon sécante par rapport à la partie externe 9 (figure 22b). Cela permet alors de définir une solution de continuité 20c, ou une coupure 20b, ou une zone frangible 20a au point bas 31.
  • soit enfin, le plan P coupe le plan R1 à l'extérieur de la partie externe 9 (figure 22c). Cela définit pour la partie interne 10 une solution de continuité 20c au point bas 31.
The plane P can have, with respect to the transverse reference plane R1 defined by the edge 15, three different positions:
  • either the plane P intersects the plane R1 along a line substantially tangent to the external part 9. (FIG. 22) In this case, this defines for the internal part 10 a continuity solution 20c at the low point 31.
  • either the plane P intersects the plane R1 inside the plug itself, that is to say in a secant manner with respect to the external part 9 (FIG. 22b). This then makes it possible to define a continuity solution 20c, or a break 20b, or a frangible zone 20a at the low point 31.
  • or finally, the plane P intersects the plane R1 outside of the external part 9 (FIG. 22c). This defines for the internal part 10 a continuity solution 20c at the low point 31.

Dans une autre variante de réalisation, une partie de la partie interne 10 dépasse axialement la partie externe et une partie ne la dépasse pas (figure 22d).In another alternative embodiment, part of the internal part 10 axially exceeds the part external and a part does not exceed it (figure 22d).

Le procédé de fabrication d'un bouchon tel qu'il vient d'être décrit consiste en ce que, tout d'abord, on le réalise par injection avec la partie interne 10 venant en prolongation de la partie externe 9. Ensuite, on fait pivoter la partie interne 10 autour de son bord aminci 14 pour être ainsi retourné à l'intérieur de la bague 8.The method of manufacturing a stopper as it just described is that, first of all, we produced by injection with the internal part 10 coming in extension of the external part 9. Then, we do pivot the internal part 10 around its thinned edge 14 to be returned inside the ring 8.

La partie interne 10 étant ainsi retournée à l'intérieur de la bague 8, le bouchon 1 peut être vissé sur le récipient 2.The internal part 10 thus being returned to inside the ring 8, the plug 1 can be screwed onto container 2.

Bien que seuls certains modes de réalisation de l'invention aient été décrits, il est évident que toute modification apportée dans le même esprit par l'homme du métier ne sortirait pas du cadre de la présente invention. Par exemple toute combinaison entre elle des différentes variantes décrites ne sortirait pas du cadre de l'invention. En particulier, les dispositions particulières des moyens de liaison décrites dans les variantes une à quatre sont combinables avec l'une quelconque des variantes cinq à sept concernant l'inclinaison du bord libre.Although only certain embodiments of the invention have been described, it is obvious that any modification made in the same spirit by the man of the profession would not depart from the scope of the present invention. For example any combination of different variants described would not be beyond the scope of the invention. In particular, the special provisions connecting means described in variants one to four can be combined with any of the variants five to seven concerning the inclination of the free edge.
