Description

La présente invention concerne un dispositif pour l'obturation d'une bouteille, comprenant un bouchon à introduire dans son goulot et une coiffe (ou capsule) emmanchable sur son col, laquelle coiffe comporte deux parties l'une formant jupe et l'autre opercule, solidarisées par des moyens de liaison comportant des zones d'amorce de rupture.The present invention relates to a device for closing a bottle, comprising a cap to be introduced into its neck and a cap (or capsule) emmanchable on his neck, which cap has two parts, one forming a skirt and the other operculum secured by connecting means having rupture initiation zones.

Les bouteilles pour boisson, en particulier les bouteilles réalisées en verre, comportent un corps, ou ventre, qui se resserre en partie supérieure pour former un col terminé par un goulot.Beverage bottles, in particular bottles made of glass, have a body, or belly, which tightens at the top to form a collar terminated by a neck.

Les coiffes ou capsules, généralement dénommées coiffes de surbouchage, comprennent une jupe tubulaire pour protéger le col des bouteilles, prolongée par un opercule agencé pour protéger un bouchon rapporté au sein du goulot. La face supérieure de l'opercule amovible sert fréquemment de support pour une vignette fiscale.The caps or caps, generally called overcaps, comprise a tubular skirt to protect the neck of the bottles, extended by a cover arranged to protect a plug reported in the neck. The upper face of the removable lid is frequently used as a support for a tax sticker.

Certaines coiffes sont réalisées par moulage de matière plastique, et sont positionnées par emmanchement à force sur le col de la bouteille.Some caps are made by plastic molding, and are positioned by press fitting on the neck of the bottle.

Lorsqu'un individu souhaite ouvrir la bouteille, il lui faut retirer l'opercule, puis extraire le bouchon.When an individual wishes to open the bottle, he must remove the lid, then extract the cap.

L'enlèvement de l'opercule s'effectue parfois manuellement, ou plus généralement à l'aide d'un outil coupant approprié (par exemple un couteau, ou similaire).The removal of the lid is sometimes done manually, or more generally with the aid of a suitable cutting tool (for example a knife, or the like).

Pour réaliser une séparation nette et esthétique entre l'opercule et la jupe, comme décrit dans les documents DE-103 45 654 ou FR-2 280 560 , il peut être prévu de solidariser ces deux parties de coiffe par des moyens comportant des zones d'amorce de rupture.
La coiffe est alors équipée d'une languette périphérique amovible, placée entre la jupe et l'opercule, que l'on enlève manuellement au moment de l'ouverture de la bouteille.To achieve a clear and aesthetic separation between the cover and the skirt, as described in the documents DE-103 45 654 or FR-2 280 560 it may be provided to secure these two parts of the cap by means having breaking initiation areas.
The cap is then equipped with a removable peripheral tongue placed between the skirt and the cap, which is removed manually at the time of opening of the bottle.

Cette languette amovible n'est cependant pas toujours facile à enlever et elle complique la structure de la coiffeThis removable tongue is however not always easy to remove and it complicates the structure of the cap

D'autre part, comme décrit dans le document DE-10 2006 033 413 , qui divulgue un dispositif selon le préambule de la revendication 1, on connait encore des ensembles coiffe/bouchon associés par des moyens de came, qui sont agencés pour faciliter l'extraction du bouchon par un mouvement de rotation de la coiffe.On the other hand, as described in the document DE-10 2006 033 413 , which discloses a device according to the preamble of claim 1, there is also known associated cap / cap assemblies by cam means, which are arranged to facilitate the extraction of the cap by a rotational movement of the cap.

Avec ce type de structure, au moment de l'ouverture de la bouteille, un mouvement de rotation de la coiffe lui permet de remonter le long du col de la bouteille grâce aux moyens de came supérieurs. Et des systèmes de butées ménagées sur les parois internes de la coiffe viennent prendre appui sous la tête du bouchon qui déborde radialement du goulot, de manière à initier l'extraction du corps de bouchon enfoncé dans le goulot.With this type of structure, at the time of opening of the bottle, a rotational movement of the cap allows it to go up along the neck of the bottle through the upper cam means. And stop systems arranged on the inner walls of the cap come to bear under the head of the cap that overflows radially of the neck, so as to initiate extraction of the plug body embedded in the neck.

Mais la coiffe reste ici d'un seul tenant pour pouvoir remonter entièrement et assurer sa fonction d'extraction du bouchon ; il n'est donc aucunement question ici de sa séparation en deux parties jupe/opercule, ni de solutionner un problème lié à une telle séparation.But the cap remains here in one piece to be able to go back fully and ensure its cap extraction function; there is therefore no question here of its separation into two parts skirt / cap, nor solve a problem related to such separation.

En outre, l'aménagement des butées à l'intérieur de la coiffe nécessite la présence d'un épaulement sur le pourtour de la tête du bouchon, qui impose son débordement radial et donc oblige à un dimensionnement important inesthétique et susceptible de poser problème.In addition, the arrangement of the stops inside the cap requires the presence of a shoulder on the periphery of the cap head, which imposes its radial overflow and therefore requires a significant dimensioning unsightly and likely to cause problems.

Dans ce contexte, il existe un besoin pour un dispositif d'obturation pour bouteilles, dont l'opercule de la coiffe soit facilement détachable manuellement par rapport à la jupe de la coiffe, sans effort excessif ni accessoire.In this context, there is a need for a closure device for bottles, the lid of the cap is easily detachable manually relative to the skirt of the cap, without excessive effort or accessory.

Pour cela, le dispositif d'obturation selon l'invention comprend :

  1. (i) un bouchon comportant deux parties cylindriques s'étendant dans le prolongement l'une de l'autre selon un axe longitudinal, formant respectivement un corps de bouchon et une tête de bouchon, laquelle tête de bouchon présente un diamètre qui est supérieur au diamètre dudit corps de bouchon, et laquelle tête de bouchon comporte - une surface inférieure, raccordée audit corps de bouchon et - une surface supérieure libre, située à l'opposé de ladite surface inférieure selon ledit axe longitudinal, et
  2. (ii) une coiffé tubulaire présentant un axe longitudinal et au sein de laquelle ledit bouchon est destiné à venir se loger coaxialement, laquelle coiffe comporte deux parties s'étendant dans le prolongement l'une de l'autre selon ledit axe longitudinal, formant respectivement - une jupe, destinée à s'étendre en regard et à distance dudit corps de bouchon, comportant des moyens pour son verrouillage en translation sur la bouteille, et - un opercule, destiné à recouvrir ladite tête de bouchon, lequel opercule et laquelle jupe tubulaire sont solidarisés l'un avec l'autre par des moyens de liaison comportant des zones d'amorce de rupture.
For this purpose, the closure device according to the invention comprises:
  1. (i) a plug having two cylindrical portions extending in line with one another along a longitudinal axis, respectively forming a plug body and a plug head, which plug head has a diameter which is greater than diameter of said plug body, and which plug head has - a bottom surface, connected to said plug body and - a free top surface, located opposite said bottom surface along said longitudinal axis, and
  2. (ii) a tubular hairstyle having a longitudinal axis and in which said plug is intended to be housed coaxially, which cap comprises two parts extending in the extension of one another along said longitudinal axis, respectively forming a skirt intended to extend facing and at a distance from said cap body, comprising means for locking it in translation on the bottle, and a cap for covering said cap head, which covers and which tubular skirt are secured to one another by connecting means having breaking initiation zones.

Conformément à l'invention, la tête de bouchon et l'opercule comportent des moyens de came qui coopèrent entre eux pour provoquer, lors d'une manoeuvre en rotation dudit opercule par rapport à ladite tête de bouchon autour desdits axes longitudinaux, un mouvement en translation dudit opercule par rapport à ladite tête de bouchon selon lesdits axes longitudinaux et dans un sens orienté depuis la surface inférieure vers la surface supérieure de ladite tête de bouchon, de sorte qu'une fois ce dispositif d'obturation convenablement rapporté sur le goulot d'une bouteille, ladite manoeuvre manuelle en rotation dudit opercule de coiffe provoque un écartement des bordures solidarisées et ainsi la dégradation desdits moyens de liaison.According to the invention, the cap head and the cap comprise cam means which cooperate with one another to cause, during a rotational operation of said cap relative to said cap head about said longitudinal axes, a movement in translation of said cap relative to said cap head along said longitudinal axes and in a direction directed from the lower surface towards the upper surface of said cap head, so that once this closure device is properly attached to the neck of the cap; a bottle, said manual maneuver in rotation of said cap cap causes a spacing of the joined edges and thus the degradation of said connecting means.

Cette structure est intéressante du fait de sa simplicité et en ce qu'elle permet de dégrader les moyens de liaison par un effort relativement réduit.This structure is interesting because of its simplicity and in that it allows to degrade the connecting means by a relatively reduced effort.

Elle permet en plus de conserver un mouvement de rotation pour le détachement de l'opercule et pour la rupture des moyens de liaison, du type présent sur les capsules à vis, cela sur une bouteille dont le goulot est dépourvu de profil particulier, notamment d'un filetage ou d'un pas de vis.
On évite ainsi l'emploi d'une bouteille munie d'un filetage au niveau du goulot, avec les coûts de revient élevés et les problèmes d'étanchéité qui en découlent.It also makes it possible to maintain a rotational movement for detaching the lid and for breaking the connecting means, of the type present on the screw caps, on a bottle whose neck has no particular profile, particularly a thread or a screw thread.
This avoids the use of a bottle with a thread at the neck, with high cost and sealing problems that result.

D'autres caractéristiques avantageuses de l'invention, pouvant être prises indépendamment ou en combinaison, sont précisées ci-dessous.Other advantageous features of the invention, which can be taken independently or in combination, are specified below.

Les moyens de came comprennent avantageusement deux parties, l'une ménagée sur ledit opercule et l'autre ménagée sur ladite tête de bouchon, avec :

De préférence, la première partie des moyens de came comporte plusieurs paires de rampes successives (au moins deux paires de rampes), réparties autour de l'axe longitudinal, lesquelles paires de rampes comportent chacune un point de jonction à partir duquel s'étendent lesdites deux rampes avec chacune une pente ascendante selon un sens de rotation inverse l'une par rapport à l'autre ; et les pions comportent une surface d'extrémité en Vé dont les pentes sont complémentaires desdites deux rampes ; cette structure particulière autorise une manoeuvre manuelle en rotation de l'opercule selon deux sens inverses l'un par rapport à l'autre, horaire et anti-horaire (dits encore « droite » et « gauche »).Again in this case, or the ramps each advantageously have an upward slope in a given direction of rotation about the longitudinal axis; and the one or more pins advantageously comprise an end surface having a slope complementary to said associated ramp.
Preferably, the first part of the cam means comprises several pairs of successive ramps (at least two pairs of ramps), distributed around the longitudinal axis, which pairs of ramps each comprise a junction point from which said two ramps each with an upward slope in a direction of rotation opposite to each other; and the pins have a V-shaped end surface whose slopes are complementary to said two ramps; this particular structure allows a manual operation in rotation of the lid in two opposite directions with respect to each other, hourly and anti-clockwise (also called "right" and "left").

Toujours dans ce cas, la première partie des moyens de came est avantageusement ménagée sur la tête de bouchon, et la seconde partie des moyens de came est ménagée sur l'opercule.Still in this case, the first part of the cam means is advantageously formed on the cap head, and the second part of the cam means is provided on the cap.

De préférence, la tête de bouchon comporte alors une paroi tubulaire centrale et une paroi tubulaire périphérique, à distance l'une de l'autre, dont les bordures inférieures sont raccordées par une couronne formant la surface inférieure de la tête de bouchon ; la bordure supérieure de la paroi tubulaire centrale définit la surface supérieure de la tête de bouchon, et la bordure supérieure de l'une desdites parois tubulaires constitue lesdites rampes.
L'opercule comporte avantageusement une paroi tubulaire prolongeant une paroi de fond ; en outre, la surface intérieure de ladite paroi tubulaire de l'opercule et la surface intérieure des pions de l'opercule coopèrent, respectivement, avec les parois tubulaires périphérique et centrale de la tête de bouchon pour le guidage en rotation dudit opercule.Preferably, the plug head then comprises a central tubular wall and a peripheral tubular wall, at a distance from one another, the edges of which lower are connected by a ring forming the lower surface of the plug head; the upper edge of the central tubular wall defines the upper surface of the plug head, and the upper edge of one of said tubular walls constitutes said ramps.
The lid advantageously comprises a tubular wall extending a bottom wall; in addition, the inner surface of said tubular wall of the cap and the inner surface of the pins of the cap cooperate, respectively, with the peripheral and central tubular walls of the cap head for rotational guiding said cap.

Selon un mode de réalisation préféré, la tête de bouchon et l'opercule comportent encore :

  • des moyens de butée en rotation, pour limiter la manoeuvre en rotation dudit opercule par rapport à ladite tête de bouchon sur un secteur angulaire donné et ainsi définir une position de fin de course écartée, et
  • des moyens de verrouillage pour bloquer, au moins en translation, ledit opercule sur ladite tête de bouchon, dans ladite position écartée.
According to a preferred embodiment, the cap head and the cap further comprise:
  • rotational stop means for limiting the rotational operation of said cap relative to said plug head over a given angular sector and thus defining a remote end position, and
  • locking means for locking, at least in translation, said lid on said plug head, in said spaced position.

Les moyens de butée comprennent avantageusement au moins une cloison radiale, contre laquelle vient buter l'un des pions lors de la manoeuvre de l'opercule en position écartée.The abutment means advantageously comprise at least one radial partition, against which abuts one of the pins during the operation of the operculum in the separated position.

Les moyens de verrouillage consistent avantageusement en des structures complémentaires coopérant par emboîtement élastique du type clipsage.The locking means advantageously consist of complementary structures cooperating by elastic interlocking clipping type.

Ces moyens de verrouillage par emboîtement élastique sont de préférence ménagés pour assurer également le maintien de la tête de bouchon dans ledit opercule avant la manoeuvre en rotation de ce dernier.These locking means by elastic interlocking are preferably formed to also ensure the maintenance of the plug head in said lid before the rotating operation of the latter.

L'opercule comporte encore de préférence une paroi tubulaire dont la surface extérieure est munie d'un motif facilitant l'agrippement, notamment pour sa manoeuvre en rotation.The lid preferably further comprises a tubular wall whose outer surface is provided with a pattern facilitating the gripping, in particular for its maneuver in rotation.

La présente invention concerne également une bouteille équipée d'un dispositif d'obturation tel que défini ci-dessus, cette bouteille comportant avantageusement un goulot dépourvu de profil particulier, notamment de filetage.The present invention also relates to a bottle equipped with a closure device as defined above, this bottle advantageously comprising a neck devoid of particular profile, especially thread.

Tel que représenté sur les figures 1 à 4, le dispositif d'obturation 1 selon l'invention est destiné à être rapporté sur une bouteille B. As shown on the Figures 1 to 4 , the shutter device 1 according to the invention is intended to be attached to a bottle B.

La bouteille B, de structure classique, est avantageusement destinée à contenir une boisson, en particulier du vin.Bottle B , of conventional structure, is advantageously intended to contain a beverage, in particular wine.

Une telle bouteille B est avantageusement réalisée en verre.Such a bottle B is advantageously made of glass.

Cette bouteille B comprend un corps (dénommé encore « ventre » ou « fût », non représenté), surmonté d'un col C (figures 1 à 4) plus étroit et effilé, lui-même terminé par un goulot G (visible sur les figures 3 et 4).This bottle B comprises a body (also called "belly" or "barrel", not shown), surmounted by a neck C ( Figures 1 to 4 ) narrower and tapered, itself terminated by a G neck (visible on the Figures 3 and 4 ).

Le col C comporte un collet monobloc D (visible sur figures 3 et 4), désigné couramment sous l'appellation de « bague », destiné à coopérer avec le dispositif d'obturation 1.The collar C has a one-piece collar D (visible on Figures 3 and 4 ), commonly referred to as a "ring", intended to cooperate with the closure device 1.

Le collet monobloc D consiste en une bague monobloc choisie parmi notamment les catégories courantes suivantes : « bague cétie » ou « bague plate unique », « bague cétie carrée », « bague carrée » ou « bague pleine ».The one-piece collar D consists of a monoblock ring selected from among the following common categories: "CÉTIE ring" or "single flat ring", "square-shaped ring", "square ring" or "full ring".

Le dispositif d'obturation 1 selon l'invention, représenté sur les figures 1 à 5, se compose ici de deux pièces distinctes :

  1. (i) un bouchon 2 (visible sur les figures 3 à 5) qui comporte - un corps de bouchon 3, destiné à fermer le goulot G pour empêcher l'écoulement de liquide, et - une tête de bouchon 4, destinée à venir reposer sur le goulot G et dans le prolongement du col C, et
  2. (ii) une coiffe tubulaire 5 qui comporte - une jupe tubulaire 6, destinée à s'étendre en regard du corps de bouchon 3 et à recouvrir au moins une partie de la hauteur du col C de la bouteille B, et - un opercule 7, destiné à recouvrir la tête 4 du bouchon 2.
The shutter device 1 according to the invention, represented on the Figures 1 to 5 , consists here of two separate pieces:
  1. (i) a plug 2 (visible on the Figures 3 to 5 ) which comprises - a plug body 3 intended to close the neck G to prevent the flow of liquid, and - a plug head 4 intended to rest on the neck G and in the extension of the neck C , and
  2. (ii) a tubular cap 5 which comprises - a tubular skirt 6 intended to extend facing the cap body 3 and to cover at least a portion of the height of the neck C of the bottle B, and - a cap 7 , intended to cover the head 4 of the plug 2.

Le bouchon 2 et la coiffe tubulaire 5 sont avantageusement réalisés par moulage d'une matière plastique, par exemple du polyéthylène haute densité. Ils constituent ici chacun une pièce monobloc.The cap 2 and the tubular cap 5 are advantageously made by molding a plastic material, for example high density polyethylene. They constitute here each a monobloc piece.

En particulier, la jupe tubulaire 6 et l'opercule 7 de la coiffe 5 sont solidarisés l'un avec l'autre par des moyens de liaison 8 comportant des zones d'amorce de rupture 8a ; ces moyens de liaison 8 sont décrits plus en détails ci-après en relation avec les figures 11 à 14.In particular, the tubular skirt 6 and the cover 7 of the cuff 5 are made integral with one another by connecting means 8 having predetermined breaking zones 8 a; these connecting means 8 are described in more detail below in connection with the Figures 11 to 14 .

Selon l'invention, la tête 4 du bouchon 3 et l'opercule 7 de la coiffe 5 coopèrent entre eux par des moyens de came pour guider une manoeuvre de cet opercule 7 selon un mouvement hélicoïdal par rapport à la tête de bouchon 4 associée, de manière à limiter l'effort et à optimiser le mouvement nécessaire à la rupture des moyens de liaison 8 une fois ce dispositif d'obturation 1 installé sur une bouteille B.
De plus, l'opercule 7 de la coiffe 5 présente ici l'intérêt de pouvoir faire partie intégrante du bouchon 2 (figure 4), pour faciliter les opérations d'extraction et de mise en place de ce dernier.According to the invention, the head 4 of the cap 3 and the cap 7 of the cap 5 cooperate with each other by cam means to guide a maneuvering of this cap 7 in a helical movement with respect to the associated cap head 4, so as to limit the effort and optimize the movement required to break the connection means 8 once the closure device 1 installed on a bottle B.
In addition, the cap 7 of the cap 5 here has the advantage of being able to be an integral part of the cap 2 ( figure 4 ), to facilitate the operations of extraction and implementation of the latter.

La structure du bouchon 2 est décrite plus en détails ci-dessous en relation avec les figures 6 à 10.The structure of the plug 2 is described in more detail below in connection with the Figures 6 to 10 .

Le corps 3 et la tête 4 du bouchon 2 constituent deux parties cylindriques qui s'étendent dans le prolongement l'une de l'autre et coaxialement l'une par rapport à l'autre selon un axe longitudinal 2'.The body 3 and the head 4 of the plug 2 constitute two cylindrical portions which extend in the extension of one another and coaxially with respect to one another along a longitudinal axis 2 '.

Le corps 3 du bouchon 2 se compose ici d'une paroi tubulaire 10 dont la bordure inférieure, opposée à la tête de bouchon 4, est raccordée à une paroi de fond 11.The body 3 of the plug 2 here consists of a tubular wall 10 whose bottom edge, opposite the plug head 4, is connected to a bottom wall 11.

La paroi tubulaire 10 s'étend coaxialement à l'axe longitudinal 2' précité ; la paroi de fond 11 s'étend perpendiculaire à ce même axe longitudinal 2'.The tubular wall 10 extends coaxially with the aforementioned longitudinal axis 2 '; the bottom wall 11 extends perpendicular to the same longitudinal axis 2 '.

La paroi tubulaire 10 est pourvue de moyens d'étanchéité 12, constitués ici par plusieurs nervures annulaires d'étanchéité superposées.
Ces moyens d'étanchéité 12 sont destinés à épouser la surface intérieure du col C, au niveau du goulot G, pour empêcher tout écoulement de liquide.The tubular wall 10 is provided with sealing means 12, constituted here by a plurality of superimposed annular sealing ribs.
These sealing means 12 are intended to fit the inner surface of the neck C , at the neck G , to prevent any flow of liquid.

La tête 4 du bouchon 2 présente un diamètre qui est supérieur au diamètre du corps 3 du bouchon 2, et qui est sensiblement égal, voire légèrement inférieur, au diamètre extérieur du goulot G de la bouteille B.The head 4 of the plug 2 has a diameter which is greater than the diameter of the body 3 of the plug 2, and which is substantially equal to or even slightly less than the external diameter of the neck G of the bottle B.

Cette tête 4 de bouchon 2 est délimitée - par une surface inférieure 13, raccordée audit corps de bouchon 3 et formant un épaulement inférieur annulaire, et - une surface supérieure 14, située à l'opposé de ladite surface inférieure 13 et du corps 3 de bouchon 2 selon ledit axe longitudinal 2'.This plug head 2 is delimited by a lower surface 13, connected to said plug body 3 and forming an annular lower shoulder, and an upper surface 14 situated opposite said lower surface 13 and the body 3 of the plug. plug 2 along said longitudinal axis 2 '.

Ces surfaces inférieure 13 et supérieure 14 s'étendent ici chacune dans un plan perpendiculaire à l'axe longitudinal 2' du bouchon 2.These bottom 13 and top 14 surfaces each extend in a plane perpendicular to the longitudinal axis 2 'of the cap 2.

La tête 4 se compose ici de deux parois tubulaires 15 et 16, s'étendant coaxialement l'une par rapport à l'autre et coaxialement à l'axe longitudinal 2'.The head 4 here consists of two tubular walls 15 and 16, extending coaxially with each other and coaxially with the longitudinal axis 2 '.

Une première paroi tubulaire 15, centrale, est formée par une bande supérieure de la paroi tubulaire 10 du corps 3, à l'opposé de la paroi de fond 11 (figure 8).A first central tubular wall 15 is formed by an upper band of the tubular wall 10 of the body 3, opposite the bottom wall 11 ( figure 8 ).

La bordure supérieure libre 15a de cette paroi tubulaire centrale 15, de forme circulaire vue de dessus (figure 10), s'étend ici dans un plan orienté perpendiculairement à l'axe longitudinal 2' et définit la surface supérieure 14 de la tête de bouchon 4.The upper free edge 15 a of this central tubular wall 15, of circular shape seen from above ( figure 10 ), extends here in a plane oriented perpendicularly to the longitudinal axis 2 'and defines the upper surface 14 of the plug head 4.

La seconde paroi tubulaire 16, périphérique, s'étend quant à elle parallèlement et à distance de la paroi centrale 15.
Cette paroi tubulaire périphérique 16 constitue la surface périphérique cylindrique de la tête 4 du bouchon 2.The second peripheral tubular wall 16 extends in parallel and at a distance from the central wall 15.
This tubular peripheral wall 16 constitutes the cylindrical peripheral surface of the head 4 of the stopper 2.

La bordure supérieure libre 16a de cette paroi tubulaire extérieure 16 est de forme annulaire/circulaire vue de dessus (figure 10), et présente un profil constitué d'une pluralité de rampes hélicoïdales 17 successives pour constituer une partie coulisse des moyens de came.The free upper edge 16a of the outer tubular wall 16 is annular / circular top view ( figure 10 ), and has a profile consisting of a plurality of successive helical ramps 17 to form a slide portion of the cam means.

Les rampes 17 sont réparties autour de l'axe longitudinal 2' et s'étendent chacune sur un secteur angulaire donné.The ramps 17 are distributed around the longitudinal axis 2 'and each extend over a given angular sector.

Chacune de ces rampes 17 présente une pente ascendante selon un sens de rotation donné autour de l'axe longitudinal 2'.Each of these ramps 17 has an upward slope in a given direction of rotation about the longitudinal axis 2 '.

Par « pente ascendante », on entend le sens de rotation (horaire ou anti-horaire, selon le cas) dans lequel la rampe 17, vue de dessus (figure 10), chemine depuis une extrémité amont située du côté de la surface inférieure 13 de la tête 4 jusqu'à une extrémité aval située du côté de la surface supérieure 14 de la même tête 4."Upward slope" means the direction of rotation (clockwise or anticlockwise, as the case may be) in which ramp 17, viewed from above ( figure 10 ), runs from an upstream end located on the side of the lower surface 13 of the head 4 to a downstream end located on the side of the upper surface 14 of the same head 4.

Plus précisément, la bordure supérieure 16a de cette paroi tubulaire extérieure 16 comporte plusieurs paires de rampes 17 successives, ici au nombre de quatre, réparties autour de l'axe longitudinal 2'.More specifically, the upper edge 16a of the outer tubular wall 16 comprises a plurality of pairs of successive ramps 17, here four in number, distributed about the longitudinal axis 2 '.

Chaque paire de rampes 17 comporte un point de jonction amont 18 situé du côté de la surface inférieure 13, à partir duquel s'étendent les deux rampes 17 avec chacune une pente ascendante selon un sens de rotation inverse l'une par rapport à l'autre.
Ainsi, tel que représenté sur les figures 7 et 10 et tenant compte de l'axe longitudinal 2', chaque paire comporte une première rampe 17a croissante dans un sens horaire et une seconde rampe 17b croissante dans un sens inverse, anti-horaire.Each pair of ramps 17 has an upstream junction point 18 located on the side of the lower surface 13, from which extend the two ramps 17 each with an upward slope in a direction of rotation opposite to one another. other.
Thus, as represented on the Figures 7 and 10 and taking into account the longitudinal axis 2 ', each pair comprises a first ramp 17a increasing in a clockwise and a second ramp 17b increasing in a direction opposite direction, counterclockwise.

Les deux rampes 17 ont avantageusement la même valeur de pente par rapport au plan perpendiculaire à l'axe longitudinal 2'.The two ramps 17 advantageously have the same slope value with respect to the plane perpendicular to the longitudinal axis 2 '.

Chaque paire de rampes 17 présente ainsi, vue de côté, une forme générale de Vé s'ouvrant en direction de la surface supérieure 14.Each pair of ramps 17 thus has, viewed from the side, a general shape of V e opening in the direction of the upper surface 14.

Dans le présent mode de réalisation, une première rampe 17a d'une paire est en plus directement raccordée avec une seconde rampe 17b d'une paire juxtaposée. Cette liaison est réalisée par un point de jonction aval 19 qui se situe dans le plan passant par la surface supérieure 14 (c'est-à-dire ici le plan passant par la bordure libre 15a de la paroi tubulaire centrale 15) ou approximativement dans ce plan.In this embodiment, a first ramp 17a of a pair is further directly connected with a second ramp 17b of a juxtaposed pair. This connection is performed by a downstream junction point 19 which lies in the plane passing through the upper surface 14 (that is to say here the plane passing through the free edge 15a of the central tubular wall 15) or approximately in this plan.

La paroi tubulaire extérieure 16 est encore munie, au niveau de sa surface extérieure, de plusieurs nervures annulaires superposées 20.
Tel que développé ci-après, ces nervures annulaires 20 constituent des moyens de verrouillage destinés à bloquer l'opercule 7 sur la tête de bouchon 4 dans une position de fin de course pivotée.The outer tubular wall 16 is further provided, at its outer surface, with several superposed annular ribs 20.
As developed below, these annular ribs 20 constitute locking means for locking the cap 7 on the cap head 4 in a rotated end position.

En outre, les parois tubulaires 15 et 16 délimitent, entre elle, un espace annulaire 21 en forme de couronne, qui s'ouvre du côté de la surface supérieure 14.In addition, the tubular walls 15 and 16 delimit, between it, an annular space 21 in the form of a crown, which opens on the side of the upper surface 14.

Ces parois tubulaires 15 et 16 sont reliées par des cloisons radiales 22, ménagées chacune au niveau de l'un des points de jonction aval 19 raccordant deux paires de rampes 17.
Tel que développé ci-après, ces cloisons radiales 22 constituent des moyens de butée pour limiter la manoeuvre en rotation de l'opercule 7 de la coiffe 5 par rapport à la tête 4 du bouchon 2 sur un secteur angulaire donné, et ainsi définir une position de fin de course correspondant à la position écartée pivotée.These tubular walls 15 and 16 are connected by radial partitions 22, each formed at one of the downstream junction points 19 connecting two pairs of ramps 17.
As developed below, these radial partitions 22 constitute abutment means for limiting the rotational operation of the cap 7 of the cap 5 relative to the head 4 of the plug 2 on a given angular sector, and thus to define a end position corresponding to the rotated spread position.

Pour être complet, les bordures inférieures de ces deux parois tubulaires 15 et 16 sont raccordées par une couronne 23 formant la surface inférieure 13 de la tête de bouchon 4.To be complete, the lower edges of these two tubular walls 15 and 16 are connected by a ring 23 forming the lower surface 13 of the plug head 4.

En l'occurrence et uniquement à titre d'exemple, le corps de bouchon 3 et la tête de bouchon 4 présentent, respectivement, un diamètre de l'ordre de 17 à 20 mm et de l'ordre de 24 à 28 mm ; le corps de bouchon 3 et la tête de bouchon 4 présentent encore, respectivement, une hauteur de l'ordre de 14 à 21 mm et de l'ordre de 5 à 10 mm. Ces dimensions sont adaptées à façon, en fonction de la bouteille à équiper.In this case and only by way of example, the plug body 3 and the plug head 4 have, respectively, a diameter of the order of 17 to 20 mm and of the order of 24 to 28 mm; the plug body 3 and the plug head 4 still have, respectively, a height of the order of 14 to 21 mm and of the order of 5 to 10 mm. These dimensions are adapted to the way, depending on the bottle to be equipped.

Les paires de rampes 17 sont au nombre de quatre, et s'étendent chacune sur un secteur angulaire F de l'ordre de 90°.The pairs of ramps 17 are four in number, and each extends over an angular sector F of the order of 90 °.

Chaque rampe 17 s'étend ainsi avantageusement sur un secteur angulaire G de 45°, entre un point de jonction amont 18 et un point de jonction aval 19, avec une pente ascendante entre ces deux points.Each ramp 17 thus advantageously extends over an angular sector G of 45 °, between an upstream junction point 18 and a downstream junction point 19, with an ascending slope between these two points.

A titre d'exemple, vue de côté selon la figure 7, chaque rampe 17 définit un angle A avec un plan perpendiculaire à l'axe longitudinal 2', dont la valeur est avantageusement de l'ordre de 5° à 45°, de préférence de l'ordre de 13° à 15°.For example, side view according to the figure 7 each ramp 17 defines an angle A with a plane perpendicular to the longitudinal axis 2 ', the value of which is advantageously of the order of 5 ° to 45 °, preferably of the order of 13 ° to 15 °.

Les deux rampes 17 d'une paire définissent ainsi entre elles un angle de préférence de l'ordre de 150° à 154°.The two ramps 17 of a pair thus define between them an angle of preference of the order of 150 ° to 154 °.

La hauteur E, séparant le point de jonction amont 18 et le point de jonction aval 19, est par exemple de l'ordre de 1,5 mm à 6 mm (figure 7).The height E , separating the upstream junction point 18 and the downstream junction point 19, is for example of the order of 1.5 mm to 6 mm ( figure 7 ).

La coiffe tubulaire 5 est décrite quant à elle ci-dessous en relation avec les figures 11 à 14.The tubular cap 5 is described as for it below in relation to the Figures 11 to 14 .

La jupe 6 et l'opercule 7 de cette coiffe 5 constituent deux parties cylindriques qui s'étendent dans le prolongement l'une de l'autre, cela selon un axe longitudinal 5'. Par souci de simplification, on désigne ainsi l'axe longitudinal de la jupe 6 et l'axe longitudinal de l'opercule 7 par le même repère 5'.The skirt 6 and the cover 7 of this cap 5 constitute two cylindrical portions which extend in the extension of one another, that along a longitudinal axis 5 '. For the sake of simplification, the longitudinal axis of the skirt 6 and the longitudinal axis of the cap 7 are thus designated by the same reference numeral 5 '.

La jupe 6 présente avantageusement une structure telle que décrite dans le document FR-2 946 960 .The skirt 6 advantageously has a structure as described in the document FR-2,946,960 .

Cette jupe 6 est délimitée par deux bordures annulaires : - une bordure inférieure 25, à l'opposée de l'opercule 7, et - une bordure supérieure 26, située du côté de l'opercule 7.This skirt 6 is delimited by two annular borders: - a lower edge 25, opposite the operculum 7, and - an upper edge 26, located on the side of the lid 7.

La bordure supérieure 26 de la jupe 5 comporte une petite lèvre périphérique 27, en saillie vers l'extérieur, qui est structurée pour limiter, voire éviter, la formation de gouttes lorsque, après le service, on relève la bouteille B équipée.The upper edge 26 of the skirt 5 comprises a small outwardly projecting peripheral lip 27, which is structured to limit or even prevent the formation of drops when, after the service, the equipped bottle B is raised.

Cette lèvre monobloc 27 s'étend sur toute la périphérie de la bordure supérieure 26 de la jupe 5 ; elle présente une section triangulaire dont la base est solidaire de la jupe 5 et dont l'épaisseur décroit progressivement en s'éloignant de l'axe longitudinal 5' (visible en particulier figures 15 et 16).This one-piece lip 27 extends over the entire periphery of the upper edge 26 of the skirt 5; it has a triangular section whose base is integral with the skirt 5 and whose thickness decreases progressively away from the longitudinal axis 5 '(visible in particular Figures 15 and 16 ).

La face supérieure de la lèvre 27 est plane, et elle s'étend dans un plan perpendiculaire à l'axe longitudinal 5'. Son côté inférieur, qui raccorde la pointe à la jupe 5 est plan ou sensiblement plan ; il s'étend de manière rentrante du haut vers le bas, formant un angle par rapport au plan de la face supérieure compris entre 5° et 40° (de préférence de l'ordre de 30°).The upper face of the lip 27 is flat, and it extends in a plane perpendicular to the longitudinal axis 5 '. Its lower side, which connects the tip to the skirt 5 is plane or substantially plane; it extends in a reentrant manner from top to bottom, forming an angle with respect to the plane of the upper face between 5 ° and 40 ° (preferably of the order of 30 °).

D'autre part, la largeur de la face supérieure de la lèvre 27, partant de la face externe de la jupe 5, est comprise entre 0,1 et 0,8 mm, de préférence voisine de 0,5 ou 0,6 mm.On the other hand, the width of the upper face of the lip 27, starting from the outer face of the skirt 5, is between 0.1 and 0.8 mm, preferably close to 0.5 or 0.6 mm. .

Cette jupe 6 comporte encore des moyens pour sa solidarisation efficace sur le col C de la bouteille B muni du collet monobloc D.This skirt 6 further comprises means for its effective attachment to the neck C of the bottle B provided with the one-piece collar D.

Ces moyens de verrouillage consistent ici en une gorge interne annulaire 28, s'ouvrant vers l'axe longitudinal 5' et définie par deux épaulements annulaires (formant ainsi un décrochement annulaire vers l'extérieur), au sein de laquelle vient se loger le collet monobloc D précité par emboîtement à force.These locking means here consist of an annular internal groove 28, opening towards the longitudinal axis 5 'and defined by two annular shoulders (thus forming an annular recess towards the outside), within which the collar is housed monoblock D aforesaid by interlocking force.

La bande supérieure de la jupe 6, qui s'étend au-dessus de cette gorge interne 28, a avantageusement un diamètre constant, ou sensiblement constant, jusqu'à la bordure supérieure 26.The upper band of the skirt 6, which extends above this internal groove 28, advantageously has a constant diameter, or substantially constant, to the upper edge 26.

L'opercule 7 se compose quant à lui d'une paroi tubulaire 29 qui est délimitée - par une bordure supérieure 29a raccordée à une paroi de fond 30, et - par une bordure inférieure 29b, liée avec la bordure supérieure 26 de la jupe tubulaire 6.The cap 7 consists for its part of a tubular wall 29 which is defined - by an upper edge 29 has connected to a bottom wall 30, and - by a lower edge 29 b, connected with the upper edge 26 of the tubular skirt 6.

La paroi tubulaire 29 s'étend coaxialement à l'axe longitudinal 5' précité ; la paroi de fond 30 s'étend perpendiculairement à ce même axe longitudinal 5'.The tubular wall 29 extends coaxially with the aforementioned longitudinal axis 5 '; the bottom wall 30 extends perpendicularly to the same longitudinal axis 5 '.

Tel que représenté sur la figure 15, cet opercule 7 comporte une surface intérieure 7a destinée à recouvrir la tête de bouchon 4, qui est formée par :

  • la surface intérieure 29c de la paroi tubulaire 29, destinée à venir en regard de la paroi périphérique 16 de la tête de bouchon 4, et
  • la surface inférieure 30a de la paroi de fond 30, destinée à venir en regard de la surface supérieure 14 de la tête de bouchon 4.
As shown on the figure 15 This cover 7 has an inner surface 7a for covering the plug head 4, which is formed by:
  • the inner surface 29c of the tubular wall 29, intended to come opposite the peripheral wall 16 of the plug head 4, and
  • the lower surface 30 a of the bottom wall 30, intended to come next to the upper surface 14 of the plug head 4.

Cette surface intérieure 7a est équipée de plusieurs pions monoblocs 31 qui sont destinés chacun à coopérer avec l'une des paires de rampes 17 de la tête de bouchon 7, pour constituer une partie coulisseau des moyens de came.This inner surface 7a is equipped with several one-piece pins 31 which are each intended to cooperate with one of the pairs of ramps 17 of the plug head 7, to constitute a runner portion of the cam means.

Pour cela, les pions monoblocs 31 sont répartis autour de l'axe longitudinal 5', et ils sont espacés les uns des autres du secteur angulaire F pour coopérer avec l'une au moins des rampes 17.
En l'occurrence, ces pions 31, au nombre de quatre, sont espacés d'un secteur angulaire F de l'ordre de 90°, autour de l'axe longitudinal 5'.For this purpose, the one-piece pins 31 are distributed around the longitudinal axis 5 ', and they are spaced from each other from the angular sector F to cooperate with at least one of the ramps 17.
In this case, these pins 31, four in number, are spaced from an angular sector F of the order of 90 °, about the longitudinal axis 5 '.

Les pions 31 sont ici raccordés à la surface inférieure 30a de la paroi de fond 30 et à la surface intérieure 29c de la paroi tubulaire 29.The pins 31 are here connected to the lower surface 30 a of the bottom wall 30 and the inner surface 29c of the tubular wall 29.

Ces pions 31 comportent une surface inférieure libre 32, à l'opposé de la paroi de fond 30, destinée à coopérer avec les rampes 17 de la tête de bouchon 4 (visible sur les figures 14, 15 et 16).These pins 31 comprise a lower free surface 32, opposite the bottom wall 30, intended to cooperate with the ramps 17 of the plug head 4 (visible on the figures 14 , 15 and 16 ).

Pour cela, cette surface inférieure 32 est diédrique, présentant une forme générale de Vé qui se compose de deux volets 32a et 32b inclinés l'un par rapport à l'autre.For this, the bottom surface 32 is dihedral, being generally V-shaped, which consists of two parts 32 a and 32 b are inclined with respect to one another.

Les volets 32a et 32b s'étendent depuis un point de jonction amont 32c, ménagé à distance de la paroi de fond 30, et présentent chacun une pente ascendante selon un sens de rotation inverse l'un par rapport à l'autre.The shutters 32 a and 32 b extend from a junction point upstream 32 c, arranged at a distance from the bottom wall 30, and each have an upward slope in a reverse direction of rotation relative to each other .

Par « pente ascendante », pour l'opercule 7 observé du côté de la face supérieure de sa paroi de fond 30, on entend le sens de rotation (horaire ou anti-horaire, selon le cas) dans lequel le volet 32a ou 32b chemine depuis une extrémité amont 32c située à distance de la paroi de fond 30 jusqu'à une extrémité aval libre située du côté de cette paroi de fond 30.
Ainsi, tel que représenté sur les figures 15 et 16, et tenant compte de l'axe longitudinal 5', un premier volet 32a est croissant dans un sens horaire et un second volet 32b est croissant dans un sens inverse, anti-horaire.By "upward slope", for the lid 7 observed on the side of the upper face of its bottom wall 30, is meant the direction of rotation (clockwise or counterclockwise, as appropriate) in which the flap 32 has or 32 b runs from an upstream end 32 c located away from the bottom wall 30 to a free downstream end located on the side of this bottom wall 30.
Thus, as represented on the Figures 15 and 16 , And taking into account the longitudinal axis 5 ', a first flap 32 a is increasing in a clockwise direction and a second flap 32b is growing in a reverse direction, counterclockwise.

Les pentes de ces volets 32a et 32b sont complémentaires, respectivement, des deux rampes 17a et 17b associées.The slopes of the flaps 32 a and 32 b are complementary, respectively, of the two ramps 17 and 17b associated.

A titre d'exemple, vu de côté selon la figure 15, chaque volet incliné 32a et 32b définit un angle A avec un plan perpendiculaire à l'axe longitudinal 5', identique ou similaire à celui décrit ci-dessus en relation avec les rampes 17 du bouchon.As an example, viewed from the side according to the figure 15 , Each inclined flap 32 a and 32 b defines an angle A with a plane perpendicular to the longitudinal axis 5 ', the same or similar to that described above in connection with the ramps 17 of the cap.

Ainsi, là encore, l'angle A est avantageusement de l'ordre de 5° à 45°, de préférence de l'ordre de 13° à 15°.Thus, again, the angle A is advantageously of the order of 5 ° to 45 °, preferably of the order of 13 ° to 15 °.

Les deux volets 32a et 32b définissent ainsi entre eux un angle avantageusement de l'ordre de 206° à 210°.The two flaps 32a and 32b thus define between them an angle advantageously in the range of 206 ° to 210 °.

La surface inférieure libre 32 des pions 31 est munie d'une nervure 33, ménagée à distance de la paroi tubulaire périphérique 29.The lower free surface 32 of the pins 31 is provided with a rib 33, arranged at a distance from the peripheral tubular wall 29.

Cette nervure 33 est destinée à venir se loger dans la couronne 21 de la tête de bouchon 4, tel qu'illustré par la figure 5, pour participer au guidage en rotation de l'opercule 7 et pour venir buter contre l'une des cloisons radiales 22.This rib 33 is intended to be housed in the ring 21 of the cap head 4, as illustrated by the figure 5 , to participate in guiding rotation of the cover 7 and to abut against one of the radial partitions 22.

Sur sa surface intérieure 29c, la paroi tubulaire 29 comporte encore des nervures annulaires superposées 34 pour constituer une seconde partie des moyens de verrouillage destinés à bloquer l'opercule 7 sur la tête de bouchon 4 dans une position pivotée par emboîtement élastique du type clipsage.On its inner surface 29c , the tubular wall 29 further comprises superimposed annular ribs 34 to form a second part of the locking means for locking the cap 7 on the cap head 4 in a pivoted position by resilient interlocking clipping type .

La paroi tubulaire 29 présente encore une surface extérieure munie d'une pluralité de stries verticales, pour faciliter son agrippement en particulier lors des opérations de mise en rotation de l'opercule 7 par un utilisateur.The tubular wall 29 also has an outer surface provided with a plurality of vertical ridges, to facilitate its gripping particularly during operations of rotation of the lid 7 by a user.

Pour être complet, les moyens de liaison 8 comportent des zones d'amorce de rupture 8a, consistant ici en des plots monoblocs d'attachement qui sont répartis autour de l'axe longitudinal 5' de la coiffe 5 (figures 13 à 15).For completeness, the connecting means 8 comprise predetermined breaking zones 8a, consisting here monoblock pads of attachment that are distributed around the longitudinal axis 5 'of the cap 5 ( Figures 13 to 15 ).

Ces zones d'amorce de rupture 8a (dont le nombre peut être compris entre 3 et 10, de préférence de l'ordre de 6) constituent des sites de moindre résistance, reliant la bordure inférieure 29b de la paroi tubulaire 29 de l'opercule 7 et la bordure supérieure 26 de la jupe 6 de la coiffe 5.These fracture initiation zones 8 has (the number can be between 3 and 10, preferably of the order of 6) are least resistance sites, connecting the lower edge 29 b of the tubular wall 29 of the opercule 7 and the upper edge 26 of the skirt 6 of the cap 5.

En pratique, le dispositif d'obturation 1 est obtenu par introduction du bouchon 2 dans la coiffe 5 (figure 5).In practice, the closure device 1 is obtained by introducing the plug 2 into the cap 5 ( figure 5 ).

Pour cela, le bouchon 2 est convenablement orienté avec sa tête 4 introduite en premier et en regard de l'opercule 7 ; le bouchon 2 est en plus orienté coaxialement à la coiffe 5 lors de cette introduction.For this purpose, the stopper 2 is suitably oriented with its head 4 inserted first and opposite the cover 7; the plug 2 is additionally oriented coaxially with the cap 5 during this introduction.

Une fois convenablement introduit (figure 5), le bouchon 2 et la coiffe 5 s'étendent coaxialement l'un par rapport à l'autre, leurs axes longitudinaux 2' et 5' étant confondus.Once properly introduced ( figure 5 ), the plug 2 and the cap 5 extend coaxially with respect to each other, their longitudinal axes 2 'and 5' being merged.

La jupe 6 de la coiffe 5 s'étend en regard et à distance du corps de bouchon 3.The skirt 6 of the cap 5 extends opposite and at a distance from the cap body 3.

L'opercule 7 de la coiffe 5 recouvre la tête de bouchon 4, avec sa paroi de fond 30 en appui sur la surface supérieure 14 de la tête 4 et sa paroi tubulaire 29 épousant la paroi tubulaire périphérique 16 de la tête 4.The cover 7 of the cap 5 covers the cap head 4, with its bottom wall 30 bearing on the upper surface 14 of the head 4 and its tubular wall 29 conforming to the peripheral tubular wall 16 of the head 4.

Le bouchon 2 est enfoncé de sorte que le point de jonction 32c de chaque pion 31 vienne se placer au niveau du point de jonction amont 18 d'une paire de rampes 17, et de sorte que les volets 32a et 32b de chaque pion 31 épousent respectivement les pentes 17a et 17b d'une paire (figure 15).
Cette position enfoncée est ici avantageusement maintenue par le positionnement des nervures 34 de l'opercule 7 directement sous les nervures 20 équipant la tête de bouchon 4. Cette particularité permet de dissocier l'opération d'assemblage du dispositif 1 et l'opération de pose sur une bouteille.The plug 2 is pressed so that the junction point 32 c of each pin 31 comes to lie at the upstream junction 18 of a pair of ramps 17 and so that the shutters 32 a and 32 b of each pin 31 respectively embrace the slopes 17a and 17b of a pair ( figure 15 ).
This depressed position is here advantageously maintained by the positioning of the ribs 34 of the cover 7 directly under the ribs 20 equipping the plug head 4. This feature allows to separate the assembly operation of the device 1 and the laying operation on a bottle.

Ce dispositif d'obturation 1 peut ensuite être rapporté sur une bouteille B à obturer, par emmanchement à force selon une direction coaxiale à leurs axes longitudinaux 2' et 5' confondus.This closure device 1 can then be attached to a bottle B to be plugged by press fitting in a direction coaxial with their longitudinal axes 2 'and 5' together.

Lors de cet enfoncement, la jupe de coiffe 6 vient recouvrir le col de bouteille C (figures 1 à 4) ; sa bordure supérieure 26 s'étend au niveau du goulot G. La gorge intérieure 28 reçoit le collet D de la bouteille B, pour assurer le verrouillage en translation de la jupe 6 sur le col C (figures 3 et 4).During this depression, the cap skirt 6 comes to cover the bottle neck C ( Figures 1 to 4 ); its upper edge 26 extends at the neck G. The inner groove 28 receives the collar D of the bottle B, to ensure the translation locking of the skirt 6 on the neck C ( Figures 3 and 4 ).

Dans le même temps, le corps 3 du bouchon 2 s'introduit au travers du goulot G de la bouteille B pour assurer son obturation aux liquides (figure 3).At the same time, the body 3 of the stopper 2 is introduced through the neck G of the bottle B to ensure its filling with liquids ( figure 3 ).

Cet enfoncement axial est poursuivi jusqu'à ce que la surface inférieure 13 de la tête 4 du bouchon 2 prenne appui sur le goulot G (figures 3 et 15).This axial depression is continued until the lower surface 13 of the head 4 of the cap 2 bears on the neck G ( figures 3 and 15 ).

Lorsqu'une personne souhaite accéder au liquide conditionné dans la bouteille B, il lui suffit d'exercer tout d'abord une manoeuvre en rotation sur l'opercule 7 de la coiffe 5 autour de son axe longitudinal 5', par exemple selon un sens de rotation anti-horaire sur les figures 15 et 16 (représenté par la flèche S sur la figure 16).When a person wishes to access the conditioned liquid in the bottle B, it is sufficient for him to first exert a rotating maneuver on the cap 7 of the cap 5 about its longitudinal axis 5 ', for example in one direction anti-clockwise rotation on Figures 15 and 16 (represented by the arrow S on the figure 16 ).

De manière alternative, du fait de l'agencement des rampes 17 par paires, l'utilisateur pourrait tout aussi bien faire subir un mouvement de rotation horaire à l'opercule 7.Alternatively, because of the arrangement of the ramps 17 in pairs, the user could just as well perform a rotational movement of the lid 7 hourly.

Le mouvement de rotation pour la dégradation des moyens de liaison jupe/opercule peut donc être réalisé dans les deux sens.The rotational movement for the degradation of the skirt / seal connection means can therefore be realized in both directions.

En outre, la manoeuvre de rotation correspondante peut être appliquée soit sur l'opercule, avec maintien de la bouteille, soit sur la bouteille, avec maintien de l'opercule.In addition, the corresponding rotation maneuver can be applied either to the lid, with holding the bottle, or on the bottle, with holding the lid.

L'opercule 7 est pivoté selon un secteur angulaire G donné, en l'occurrence de l'ordre de 25° à 45°, jusqu'à une position de fin de course écartée dans laquelle les pions 31 viennent chacun en butée contre l'une des cloisons radiales 22 (figure 16).The cover 7 is pivoted according to a given angular sector G , in this case of the order of 25 ° to 45 °, to a position of end of race apart in which the pins 31 each abut against the one of the radial partitions 22 ( figure 16 ).

Cette rotation de l'opercule 7 est guidée par la coopération entre :

  • la surface intérieure des pions 31 et la paroi tubulaire centrale 15 de la tête de bouchon 4,
  • la nervure 33 des pions 31 et la couronne 21 de la tête de bouchon 4, et
  • la surface intérieure 29c de la paroi tubulaire 29 de l'opercule 7 et la paroi tubulaire extérieure 16 de la tête de bouchon 4.
This rotation of the cap 7 is guided by the cooperation between:
  • the inner surface of the pins 31 and the central tubular wall 15 of the cap head 4,
  • the rib 33 of the pins 31 and the ring 21 of the plug head 4, and
  • the inner surface 29c of the tubular wall 29 of the cap 7 and the outer tubular wall 16 of the cap head 4.

Le bouchon 2 étant verrouillé en rotation par son corps 3 enfoncé dans le goulot G, les pions 31 de cet opercule 7 cheminent chacun le long de l'une des rampes 17 de chaque paire, en direction de leurs points de jonction aval 19 respectifs. En l'occurrence, le volet 32b de chaque pion 31, de pente croissante dans le sens anti-horaire, chemine le long de la rampe 17b de chaque paire, de pente croissante également dans le sens anti-horaire.The plug 2 being locked in rotation by its body 3 driven into the neck G , the pins 31 of the cover 7 each run along one of the ramps 17 of each pair, in the direction of their respective downstream junction points 19. In this case, the flap 32b of each pin 31, increasing slope in the anti-clockwise direction, runs along the ramp 17b of each pair, also increasing slope in the anti-clockwise direction.

Ce chemin de came provoque ainsi, simultanément, un déplacement de l'opercule 7 selon une rotation coaxiale aux axes longitudinaux 2' et 5', et selon un sens de translation T orienté depuis la surface inférieure 13 vers la surface supérieure 14 de la tête de bouchon 4 (figure 16).This cam path thus simultaneously causes the cap 7 to move in a rotation coaxial with the longitudinal axes 2 'and 5', and in a direction of translation T oriented from the lower surface 13 towards the upper surface 14 of the head. cap 4 ( figure 16 ).

Ce mouvement provoque l'écartement de l'opercule 7 par rapport à la jupe 6 verrouillée en translation (figure 16), et en particulier l'éloignement :

  • de la paroi de fond 30 de l'opercule 7 par rapport à la surface supérieure 14 de la tête de bouchon 4, et
  • de la bordure inférieure 29b de la paroi tubulaire 29 de l'opercule 7 par rapport à la bordure supérieure 26 de la jupe 6.
This movement causes the operculum 7 to move away from the skirt 6 locked in translation ( figure 16 ), and in particular the distance:
  • the bottom wall 30 of the cap 7 with respect to the upper surface 14 of the cap head 4, and
  • the lower edge 29b of the tubular wall 29 of the cover 7 relative to the upper edge 26 of the skirt 6.

En pratique, ce déplacement en translation est par exemple de quelques millimètres, ici de l'ordre de 1 à 5 mm.In practice, this displacement in translation is for example a few millimeters, here of the order of 1 to 5 mm.

Ce déplacement hélicoïdal de l'opercule 7, par rapport à la jupe 6, assure la dégradation des zones de rupture 8a constitutives des moyens de liaison 8, en particulier avec un effort réduit.This helical displacement of the cap 7, with respect to the skirt 6, ensures the degradation of the breaking zones 8 a constituting the connecting means 8, in particular with a reduced effort.

Dans la position écartée obtenue, les moyens de verrouillage 20, 34 coopèrent ensemble par emboîtement élastique, de sorte que l'opercule 7 est bloqué en translation dans cette position écartée par rapport à la tête de bouchon 4 (figure 16).In the spaced position obtained, the locking means 20, 34 cooperate together by elastic interlocking, so that the cover 7 is locked in translation in this position spaced from the plug head 4 ( figure 16 ).

L'opérateur peut poursuivre son effort sur l'opercule 7 par une action combinant rotation et traction, de sorte à extraire progressivement le corps de bouchon 3 par rapport au goulot G de la bouteille B (figure 4).
En particulier, si l'opérateur poursuit sa manoeuvre en rotation dans le sens anti-horaire, les pions 31 en appui sur les cloisons radiales 22 peuvent provoquer une rotation du corps de bouchon 3 dans son goulot G également dans le sens anti-horaire.The operator can continue his effort on the cover 7 by an action combining rotation and traction, so as to progressively extract the cap body 3 with respect to the neck G of the bottle B ( figure 4 ).
In particular, if the operator continues his maneuver in rotation in the counterclockwise direction, the pins 31 resting on the radial partitions 22 may cause rotation of the plug body 3 in its neck G also in the counterclockwise direction.

Le bouchon 2 et l'opercule 7, solidaire de la tête de bouchon 4, constituent ensemble une pièce détachable (figure 4).The cap 2 and the cap 7, integral with the cap head 4, together constitute a detachable piece ( figure 4 ).

Si l'utilisateur souhaite reboucher sa bouteille B, il lui suffit de saisir l'opercule 7 porté par le bouchon 2, puis de réintroduire à force le corps de bouchon 3 au sein du goulot G.If the user wishes to close his bottle B, it is sufficient for him to grasp the cap 7 carried by the stopper 2, then reintroducing the stopper body 3 into the neck G.

La position écartée précitée, obtenue par les moyens de verrouillage 20, 34, constitue un témoin d'ouverture efficace.The aforesaid spaced position, obtained by the locking means 20, 34, is an effective opening indicator.

Le dispositif d'obturation 1 selon l'invention a l'intérêt de consister en un ensemble « combiné » bouchon avec coiffe, pouvant être assemblé avant sa pose sur une bouteille.The closure device 1 according to the invention has the advantage of consisting of a "combined" cap with cap, which can be assembled before it is placed on a bottle.

De plus, ce dispositif d'obturation 1 a l'intérêt d'offrir une manoeuvre en rotation de l'opercule sur une bouteille dépourvue de pas de vis, ce qui permet de préserver dés coûts de revient limités et d'optimiser l'effort nécessaire pour la rupture des moyens de liaison.In addition, this closure device 1 has the advantage of providing a maneuver in rotation of the lid on a bottle devoid of screw thread, which allows to preserve limited cost and optimize effort necessary for the breaking of the connecting means.
