Description

L'invention concerne, selon un premier aspect, un bouchon à charnière, monopièce, pour bouteille à bague faisant office de verseur.The invention relates, according to a first aspect, to a hinged cap, one piece, for ring bottle acting as a tipper.

L'invention concerne, selon un deuxième aspect, un emballage formé d'une bouteille pourvue d'un tel bouchon.The invention relates, according to a second aspect, to a packaging formed of a bottle provided with such a stopper.

On connaít déjà des bouchons ou capsules de bouchage ayant un couvercle ou un capuchon pouvant pivoter entre une position d'ouverture pour laquelle au moins une ouverture du bouchon est découverte et une position de fermeture pour laquelle les ouvertures sont couvertes.We already know caps or capsules closure having a pivotable cover or cap between an open position for which at least one opening of the cap is discovered and a position of closure for which the openings are covered.

Ce pivotement s'effectue autour d'une ou plusieurs parties du bouchon formant charnière.This pivoting takes place around one or more parts of the plug forming a hinge.

Des exemples de telles charnières peuvent être trouvés dans les documents suivants : US-5 529 205, US-5 489 035, US-5 540 343, WO-92/13775, WO-95/23097.Examples of such hinges can be found in the following documents: US-5,529,205, US-5 489,035, US-5,540,343, WO-92/13775, WO-95/23097.

Des exemples de tels bouchons ou capsules de bouchage peuvent être trouvés dans les documents suivants : US-4 047 495, US-4 127 221, US-4 203 532, US-4 424 910, US-4 666 068, US-4 718 567, US-4 723 669, US-4 807 768, US-4 815 619, US-4 821 898, US-4 826 026, US-4 887 747, US-5 346 099, US-5 417 350, US-5 423 442, US-5 407 087, US-5 460 282, EP-B-210 138, EP-B-214 095, EP-A-401 292, EP-A-555 624, EP-A-635 436, EP-A-642 451, EP-A-685 406, WO-95/25676, WO-95/25677, FR-2 380 195, FR-2 647 088, FR-2 720 722, FR-2 731 983.Examples of such caps or capsules plugging can be found in the following documents: US-4,047,495, US-4,127,221, US-4,203,532, US-4,424,910, US-4 666 068, US-4 718 567, US-4 723 669, US-4 807 768, US-4 815 619, US-4 821 898, US-4 826 026, US-4 887 747, US-5 346 099, US-5 417 350, US-5 423 442, US-5 407 087, US-5 460 282, EP-B-210 138, EP-B-214 095, EP-A-401 292, EP-A-555 624, EP-A-635 436, EP-A-642 451, EP-A-685 406, WO-95/25676, WO-95/25677, FR-2 380 195, FR-2 647 088, FR-2 720 722, FR-2 731,983.

Dans certaines réalisations, les bouchons ou capsules de bouchage comportant un couvercle ou capuchon pouvant pivoter autour d'une charnière sont conçus de manière telle que lorsque le couvercle, le capuchon est en position d'ouverture du bouchon, l'extrémité du col de la bouteille sur laquelle est fixé le bouchon saille vers l'extérieur.In certain embodiments, the plugs or closures with a cover or cap pivotable around a hinge are designed to so that when the cover, the cap is in opening position of the cap, the end of the neck of the bottle on which the cap protrudes towards outside.

De ce fait, au moins une partie de ce col de bouteille fait alors office de verseur.Because of this, at least part of this cervix bottle then acts as pourer.

L'invention se rapporte à ce type de bouchon, ainsi qu'à une bouteille pourvue de ce type particulier de bouchon.The invention relates to this type of plug, as well than a bottle with this particular type of plug.

On connait du document FR-A-2 294 933 une fermeture pour une bouteille, qui comprend un corps annulaire de support fixé sur la bouteille, un capuchon relié au corps par une articulation, et un anneau de sécurité relié au capuchon par un élément de connexion.Document FR-A-2 294 933 discloses a closure for a bottle, which comprises an annular support body fixed to the bottle, a cap connected to the body by a joint, and a safety ring connected to the cap by a connection.

Un exemple de ce type de bouchon peut également être trouvé dans le document EP-A-680 887.An example of this type of cap can also be found in document EP-A-680 887.

De tels bouchons sont conventionnellement fixés sur les bouteilles par clippage sur une saillie annulaire externe du col des bouteilles au moyen d'un jonc en saillie annulaire interne à une ceinture d'accrochage du bouchon.Such caps are conventionally attached to bottles by clipping onto an annular projection external of the neck of the bottles by means of a projecting rod internal annular to a belt for hanging the plug.

Ce jonc est interrompu au niveau de la partie formant charnière pour le capuchon du bouchon. Lorsque l'axe de la charnière doit être placé sous le jonc d'acrochage du col de la bouteille, ce jonc est interrompu au niveau de la partie formant charnière.This ring is interrupted at the level of the part forming a hinge for the cap of the cap. When the hinge pin must be placed under the rod the neck of the bottle, this ring is interrupted at the hinge part.

Un tel système de bouchage présente certains inconvénients.Such a closure system presents certain disadvantages.

En particulier, lors du rebouchage de la capsule du bouchon, la force exercée à l'opposé de la partie formant charnière sur le capuchon pour refermer et rendre l'ensemble bouchon/bouteille étanche, tend à faire remonter la ceinture d'accrochage du bouchon à l'endroit de l'interruption du jonc d'accrochage.In particular, when filling the capsule of the plug, the force exerted opposite the forming part hinge on the cap to close and return the sealed cap / bottle assembly tends to raise the belt for hanging the plug at the place of the interruption of the snap ring.

L'invention est relative à un bouchon à charnière pour bouteille à bague faisant office de verseur, ledit bouchon ne présentant pas les inconvénients des bouchons de ce type connus dans l'art antérieur.The invention relates to a hinged plug for ring bottle serving as pourer, said cap does not have the disadvantages of this type known in the prior art.

A cette fin, l'invention est relative, selon un premier aspect, à un bouchon destiné à être associé rigidement au col d'une bouteille, ledit bouchon comprenant une ceinture d'accrochage pourvue de premiers moyens d'accrochage coopérant avec des moyens d'accrochage complémentaires disposés sur le col de ladite bouteille, ledit bouchon comprenant en outre un capuchon mobile entre une position de fermeture du bouchon et une position d'ouverture dans laquelle au moins une partie du col de la bouteille saille vers l'extérieur, au moins une partie du bouchon formant charnière entre la ceinture d'accrochage et le capuchon mobile ; les parties de bouchon formant charnière sont pourvues de seconds moyens d'accrochage coopérant avec lesdits moyens d'accrochage complémentaires disposés sur le col de la bouteille, de sorte que lors de la fermeture du capuchon, la ceinture d'accrochage reste en position prédéterminée et sensiblement fixe et ceci notamment au voisinage des parties du bouchon formant charnière.To this end, the invention is relative, according to a first aspect, with a plug intended to be associated rigidly at the neck of a bottle, said cap comprising a fastening belt provided with first means hooking cooperating with hooking means complementary arranged on the neck of said bottle, said plug further comprising a movable cap between a position for closing the cap and a position opening in which at least part of the neck of the bottle protrudes outwards, at least part of the plug forming a hinge between the hanging belt and the movable cap; the cap parts forming hinge are provided with second hooking means cooperating with said additional attachment means arranged on the neck of the bottle, so that when closing the hood, the hanging belt remains in predetermined and substantially fixed position and this especially in the vicinity of the parts of the plug forming hinge.

Selon un mode de réalisation, les premiers moyens d'accrochage sont formés par un jonc en saillie annulaire interne à la ceinture d'accrochage du bouchon, ce jonc coopérant par clippage avec une première saillie annulaire externe du col de la bouteille formant les moyens d'accrochage complémentaires. According to one embodiment, the first means hooks are formed by an annular projecting ring internal to the fastening belt of the cap, this rod cooperating by clipping with a first annular projection external of the neck of the bottle forming the means additional attachment.

Les seconds moyens d'accrochage sont formés, selon un mode de réalisation, par une saillie interne aux parties du bouchon formant charnière, cette saillie interne aux charnières coopérant par clippage avec une saillie externe du col de la bouteille.The second attachment means are formed, according to an embodiment, by a projection internal to the parts of the plug forming a hinge, this internal projection to the hinges cooperating by clipping with a projection outside of the neck of the bottle.

La partie du bouchon formant charnière comprend une zone d'articulation pour le pivotement du capuchon, cette zone d'articulation étant disposée sensiblement dans un plan inférieur au plan du jonc en saillie annulaire interne à la ceinture d'accrochage.The part of the hinge plug comprises a hinge area for pivoting the cap, this articulation zone being arranged substantially in a plane below the plane of the internal annular projecting rod to the hanging belt.

Le capuchon du bouchon comprend, selon un mode de réalisation,

  • une paroi de fond ;
  • une jupe latérale associée rigidement à une première extrémité de la charnière du bouchon, cette première extrémité étant disposée dans un plan situé au-dessus du plan de la première saillie annulaire externe du col de la bouteille.
The cap of the plug comprises, according to one embodiment,
  • a bottom wall;
  • a side skirt rigidly associated with a first end of the hinge of the stopper, this first end being arranged in a plane situated above the plane of the first external annular projection of the neck of the bottle.

Dans la suite du texte, les termes "inférieur", "supérieur", "longitudinal", "transversal" s'entendent par rapport au bouchon 1 fixé sur le col 2 d'axe D'.In the remainder of the text, the terms "lower", "upper", "longitudinal", "transverse" mean by relative to the plug 1 fixed on the neck 2 of axis D '.

Les termes "interne", "externe" sont utilisés en prenant pour référence l'intérieur de la bouteille 3 ou du col 2.The terms "internal", "external" are used in taking as a reference the inside of the bottle 3 or the col 2.

L'on se réfère maintenant à la figure 2.We now refer to Figure 2.

Le col 2 de la bouteille 3 comporte une première saillie annulaire externe 6, disposée selon un plan P2 sensiblement transversal par rapport à l'axe D'.The neck 2 of the bottle 3 has a first external annular projection 6, arranged in a plane P2 substantially transverse to the axis D '.

Cette première saillie 6 forme jonc d'accrochage pour la ceinture d'accrochage 5 du bouchon 1.This first projection 6 forms a snap ring for the fastening belt 5 of the plug 1.

Cette première saillie 6 comporte une face annulaire inférieure 7 formée, lorsqu'on s'éloigne de l'axe D', d'une première partie sensiblement tronconique 8 et d'une seconde partie sensiblement cylindrique 9 d'axe D'.This first projection 6 has a face lower annular 7 formed, when moving away from the axis D ′, of a first substantially frustoconical part 8 and of a second substantially cylindrical part 9 with axis D '.

Le col 2 de la bouteille 3 comporte une deuxième saillie annulaire externe 10 disposée selon un plan P3 sensiblement transversal par rapport à l'axe D' et parallèle à P2.The neck 2 of the bottle 3 has a second external annular projection 10 arranged in a plane P3 substantially transverse to the axis D 'and parallel to P2.

Cette deuxième saillie annulaire 10 est disposée en-dessous de la première saillie 6.This second annular projection 10 is arranged below the first projection 6.

Cette deuxième saillie annulaire 10 comporte une face supérieure 11 formée, lorsque l'on s'éloigne de l'axe D', d'une première partie annulaire 12 sensiblement parallèle à P2, d'une deuxième partie 13 sensiblement cylindrique d'axe D', d'une troisième partie 14 annulaire et sensiblement parallèle à P2, les première 12, deuxième 13 et troisième parties 14 définissant une marche 15 formant appui pour la partie inférieure 16 de la ceinture d'accrochage 5.This second annular projection 10 includes a upper face 11 formed, when moving away from the axis D ', of a first annular part 12 substantially parallel to P2, of a second part 13 substantially cylindrical with axis D ', a third annular part 14 and substantially parallel to P2, the first 12, second 13 and third parts 14 defining a step 15 forming a support for the lower part 16 of the belt hanging 5.

La deuxième saillie annulaire 10 comporte une face latérale externe 17, sensiblement cylindrique d'axe D', cette face latérale 17 étant en continuité avec la face latérale externe 18 de la ceinture d'accrochage 5 lorsque le bouchon 1 est en place sur le col 2 de la bouteille 3.The second annular projection 10 has one face lateral lateral 17, substantially cylindrical with axis D ', this lateral face 17 being in continuity with the face lateral lateral 18 of the fastening belt 5 when the cap 1 is in place on the neck 2 of the bottle 3.

La dimension radiale r1 de la troisième partie 14 de la face supérieure 11 de la saillie 10 est sensiblement égale à l'épaisseur radiale e1 de la ceinture d'accrochage 5.The radial dimension r 1 of the third part 14 of the upper face 11 of the projection 10 is substantially equal to the radial thickness e 1 of the fastening belt 5.

Lorsque le bouchon 1 est en place sur le col 2 de la bouteille 3, la face latérale interne 19 de la ceinture d'accrochage 5 est en appui, dans sa partie inférieure 20 avec la deuxième partie 13 de la face supérieure 11 de la saillie 10.When the plug 1 is in place on the neck 2 of the bottle 3, the internal lateral face 19 of the belt attachment 5 is in support, in its lower part 20 with the second part 13 of the upper face 11 of the projection 10.

Dans le même temps, la face inférieure 21 de la ceinture d'accrochage 5 est en appui sur la troisième partie 14 de la face supérieure 11 de la saillie 10.At the same time, the underside 21 of the fastening belt 5 is supported on the third part 14 of the upper face 11 of the projection 10.

L'on comprend que la marche 15 est de forme complémentaire à la forme de la partie inférieure 16 de la ceinture d'accrochage 5. We understand that step 15 is shaped complementary to the shape of the lower part 16 of the hanging belt 5.

La ceinture d'accrochage 5 comporte sur sa face latérale interne 19 et en partie supérieure 22 une saillie annulaire 23.The fastening belt 5 has on its face internal lateral 19 and upper part 22 a projection ring finger 23.

Cette saillie annulaire 23 comporte une face supérieure 24, sensiblement tronconique, venant en appui contre la face inférieure 7 de la première saillie 6, lorsque le bouchon 1 est en position sur le col 2 de la bouteille 3.This annular projection 23 has a face upper 24, substantially frustoconical, bearing against the underside 7 of the first projection 6, when the plug 1 is in position on the neck 2 of the bottle 3.

Cette saillie annulaire 23 comporte une face inférieure 24', sensiblement tronconique, cette face 24' facilitant le passage de la première saillie 6 du col 2 de la bouteille 3, lors de la mise en place du bouchon 1.This annular projection 23 has a face lower 24 ', substantially frustoconical, this face 24' facilitating the passage of the first projection 6 from the neck 2 of the bottle 3, when the cap 1 is put in place.

La face latérale externe 25 du col 2 de la bouteille 3 est distante, dans sa partie 26 située entre la première saillie 6 et la deuxième saillie 10, de la face latérale interne 19 de la ceinture d'accrochage 5.The external lateral face 25 of the neck 2 of the bottle 3 is distant, in its part 26 located between the first projection 6 and second projection 10, from the front internal lateral 19 of the fastening belt 5.

Un espace annulaire E existe entre cette face 25 et cette face 29.An annular space E exists between this face 25 and this face 29.

Cet espace E est délimité par :

  • la partie 26 sensiblement cylindrique d'axe D' de la face latérale externe 25 du col 2 ;
  • la première partie 12 de la face supérieure 11 de la deuxième saillie annulaire 10 ;
  • la partie 27 de la face latérale interne 19 de la ceinture d'accrochage 5 qui n'est pas en contact avec la première saillie 6 ou la deuxième saillie 10.
This space E is delimited by:
  • the substantially cylindrical part 26 of axis D ′ of the external lateral face 25 of the neck 2;
  • the first part 12 of the upper face 11 of the second annular projection 10;
  • the part 27 of the internal lateral face 19 of the fastening belt 5 which is not in contact with the first projection 6 or the second projection 10.

Dans le mode de réalisation représenté, la dimension radiale r2 de cet espace E dépend des dimensions radiales r3 de la partie 12 de la face 11 ainsi que de la dimension radiale r4 de la face 7 de la première saillie 6.In the embodiment shown, the radial dimension r2 of this space E depends on the dimensions radial r3 of part 12 of face 11 as well as of radial dimension r4 of the face 7 of the first projection 6.

Dans le mode de réalisation représenté, les dimensions radiales r3 et r4 sont sensiblement identiques.In the embodiment shown, the radial dimensions r3 and r4 are substantially identical.

De sorte que la seconde partie 9 de la face 7 de la première saillie 6 est située au droit de la deuxième partie 13 de la face 11 de la deuxième saillie 10. Cette partie 9 de la face 7 de la première saillie 6 étant en appui contre la surface latérale interne 19 de la ceinture d'accrochage 5, au-dessus de la saillie annulaire 23.So that the second part 9 of the face 7 of the first projection 6 is located to the right of the second part 13 of the face 11 of the second projection 10. This part 9 of the face 7 of the first projection 6 being in support against the internal lateral surface 19 of the belt attachment 5, above the annular projection 23.

L'on se réfère maintenant à la figure 3 et à la figure 5.We now refer to Figure 3 and the figure 5.

La ceinture d'accrochage 5 comporte un amincissement 28 formant un site de pliage préférentiel pour une partie 29 du bouchon 1 formant charnière.The fastening belt 5 has a thinning 28 forming a preferential folding site for a part 29 of the plug 1 forming a hinge.

Dans cet amincissement 28, l'épaisseur e2 de la ceinture d'accrochage 5 est localement inférieure à l'épaisseur el de cette ceinture, constante en dehors de cet amincissement 28.In this thinning 28, the thickness e 2 of the fastening belt 5 is locally less than the thickness el of this belt, constant outside this thinning 28.

La charnière 29 du bouchon 1 permet le pivotement du capuchon 4 par rapport à la ceinture d'accrochage 5.The hinge 29 of the plug 1 allows the pivoting of the cap 4 relative to the fastening belt 5.

Cette charnière 29 comporte une saillie interne 30 qui sera décrite plus complètement dans la suite du texte.This hinge 29 has an internal projection 30 which will be described more fully later in the text.

Le capuchon 4 comporte une paroi de fond 31 sensiblement transversale par rapport à l'axe D. The cap 4 has a bottom wall 31 substantially transverse to the axis D.

Le capuchon 4 comporte également une paroi 32 cylindrique d'axe D en saillie sur la face interne 33 de la paroi de fond 31.The cap 4 also has a wall 32 cylindrical with axis D projecting from the internal face 33 of the bottom wall 31.

Cette paroi annulaire 32 comprend une face latérale externe 34 destinée à être au contact avec une partie 35 de la face interne 36 du col 2 de la bouteille 3, lorsque le capuchon 4 est en position de fermeture.This annular wall 32 includes a lateral face external 34 intended to be in contact with a part 35 of the internal face 36 of the neck 2 of the bottle 3, when the cap 4 is in the closed position.

Dans le mode de réalisation représenté, cette paroi 32 est de hauteur, mesurée par rapport à l'axe D, différente près de la charnière 29 qu'à l'opposé de cette charnière 29.In the embodiment shown, this wall 32 is of height, measured with respect to the axis D, different near hinge 29 than opposite this hinge 29.

Le capuchon 4 comporte, à l'opposé de la charnière 29, un décrochement 37 sur sa jupe latérale 38.The cap 4 has, opposite the hinge 29, a recess 37 on its side skirt 38.

Ce décrochement 37 facilite l'ouverture manuelle du capuchon 4.This recess 37 facilitates the manual opening of the cap 4.

Lorsque le capuchon 4 est en situation de fermeture, tel que représenté en figure 4, la face inférieure 39 de la jupe 38 du capuchon 4 n'est pas en appui contre la face supérieure 42 de la ceinture d'accrochage 5.When the cap 4 is in a situation of closure, as shown in Figure 4, the face lower 39 of the skirt 38 of the cap 4 is not in support against the upper face 42 of the belt hanging 5.

De même, la face interne 33 de la paroi de fond 31 du capuchon 4 n'est pas en appui contre l'extrémité supérieure 40 du col 2 de la bouteille 3.Similarly, the internal face 33 of the bottom wall 31 of the cap 4 is not in abutment against the end upper 40 of the neck 2 of the bottle 3.

La saillie 30 de la charnière 29 vient alors en appui contre la face inférieure 7 de la première saillie 6 du col 2, empêchant ainsi un déplacement de la ceinture d'accrochage 5 lorsqu'une force F est exercée sur l'extrémité 41 du capuchon 4, opposée à la charnière 29.The projection 30 of the hinge 29 then comes in support against the underside 7 of the first projection 6 collar 2, preventing movement of the belt attachment 5 when a force F is exerted on the end 41 of the cap 4, opposite the hinge 29.

La position particulière du capuchon 4 par rapport au col 2 ou à la ceinture d'accrochage 5 présente de nombreux avantages.

  • Tout d'abord, l'extrémité supérieure 40 du col 2 de la bouteille sert directement de verseur. Ceci permet une économie de matière comportant par rapport aux bouchons recouvrant l'ouverture 43 du col 2.Dans le mode de réalisation représenté, l'extrémité supérieure 40 du col 2 comporte une saillie annulaire 44 formant rebord anti-gouttes.
  • La distance entre la face inférieure 39 de la jupe 38 du capuchon 4 et la face supérieure 42 de la ceinture d'accrochage permet la disposition d'une bande annulaire 45 dite d'inviolabilité, formant témoin de première ouverture.
The particular position of the cap 4 relative to the neck 2 or to the fastening belt 5 has many advantages.
  • First, the upper end 40 of the neck 2 of the bottle serves directly as a pourer. This allows a saving of material comprising with respect to the caps covering the opening 43 of the neck 2. In the embodiment shown, the upper end 40 of the neck 2 has an annular projection 44 forming an anti-drip rim.
  • The distance between the lower face 39 of the skirt 38 of the cap 4 and the upper face 42 of the fastening belt allows the provision of an annular band 45 called inviolability, forming a witness of first opening.

Dans le mode de réalisation représenté, cette bande d'inviolabilité 45 comporte à une extrémité une languette 46 de préhension pour son déchirage.In the embodiment shown, this strip tamper-evident 45 has a tab at one end 46 gripping for its tearing.

Cette languette 46 recouvre en partie la charnière 29.This tongue 46 partially covers the hinge 29.

Des points frangibles, des parois minces ou toute autre disposition équivalente sont prévues entre la bande 45 et le capuchon 4 et/ou la ceinture d'accrochage 5.Frangible points, thin walls or any other equivalent arrangement is provided between the band 45 and the cap 4 and / or the fastening belt 5.

L'ensemble capuchon 4, ceinture d'accrochage 5 et bande d'inviolabilité 45 peut être monopièce. The cap assembly 4, fastening belt 5 and tamper-evident tape 45 may be one-piece.

Cet ensemble peut être élaboré en un matériau plastique tel que polyéthylène, polypropylène, polyterephtalate d'éthylène.This set can be made of a material plastic such as polyethylene, polypropylene, polyethylene terephthalate.

L'ensemble capuchon 4, ceinture d'accrochage 5 et bande d'inviolabilité 45 peut être multipièces, par exemple en deux pièces, l'une correspondant au bouchon à charnière, l'autre comprenant un verseur destiné à s'adapter sur un col standard de récipient.The cap assembly 4, fastening belt 5 and tamper-evident band 45 can be multi-room, for example in two pieces, one corresponding to the hinged plug, the other comprising a pourer intended to adapt to a standard container neck.

La fixation par clippage de cet ensemble sur le col 2 d'une bouteille 3 peut être effectuée facilement, en une seule étape.Clipping of this assembly on the collar 2 of a bottle 3 can be made easily, in one single step.
