Description

La présente invention concerne des moyens de bouchage pour bouteille de vin effervescent comme par exemple le champagne.The present invention relates to corking means for bottle of sparkling wine such as champagne.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Le bouchon de champagne est un bouchon en liège naturel ou reconstitué qui est comprimé radialement et introduit à l'état comprimé sur une partie de sa hauteur dans le col d'une bouteille. Ce col présente une contre bague extérieure destinée à assurer la retenue d'un muselet qui, généralement par l'intermédiaire d'une coupelle ou d'une plaque métallique, assure le maintien du bouchon dans le col contre l'effet de la pression régnant dans la bouteille.The champagne cork is a natural or reconstituted cork that is compressed radially and introduced in the compressed state over part of its height into the neck of a bottle. This neck has a counter-outer ring intended to ensure the retention of a wire cap which, generally via a cup or a metal plate, ensures the maintenance of the plug in the neck against the effect of the pressure prevailing in the bottle.

Ce bouchage contribue à l'image et à la notoriété des vins de champagne et les consommateurs y sont sensibles et très attachés.This clogging contributes to the image and reputation of champagne wines and consumers are sensitive and very attached to it.

Et pourtant, ce type de bouchage n'est absolument plus satisfaisant. En effet, sur le plan organoleptique, le liège - dont la qualité diminue et dont la rareté augmente - ne permet plus de conserver au vin une qualité acceptable par le consommateur. Des déviations sensorielles ainsi que des phénomènes d'oxydation sont constatés de plus en plus fréquemment et les récentes études réalisées sur le sujet par les organismes de recherches ou de contrôles mettent en évidence des taux de bouteilles affectées compris entre 5 et 10 pour cent. La clientèle étrangère à cet égard est redoutable en étant particulièrement exigeante.And yet, this type of clogging is absolutely no longer satisfactory. Indeed, organoleptically, cork - whose quality is decreasing and whose scarcity increases - no longer allows the wine to maintain a quality acceptable to the consumer. Sensory deviations as well as oxidation phenomena are being observed more and more frequently and recent studies carried out on the subject by the research or control bodies reveal affected bottle rates of between 5 and 10 per cent. Foreign customers in this respect are formidable in being particularly demanding.

En outre, la nature même du bouchage est une source d'accidents au moment de l'opération d'ouverture de la bouteille par le consommateur. Le bouchon peut en effet lui échapper et être violemment projeté dans l'espace environnant, pouvant briser des objets qui s'y trouvent ou blesser une personne à proximité de la bouteille.In addition, the nature of the clogging is a source of accidents at the time of the operation of opening the bottle by the consumer. The cap can indeed escape and be violently projected into the surrounding space, may break objects that are there or injure a person near the bottle.

Par ailleurs, la compression préalable du bouchon est une source de défauts de la surface extérieure du bouchon qui coopère, avec la surface intérieure du col, à l'étanchéité du bouchage. Il peut alors exister de petites cavités qui, conjuguées avec une hystérésis de l'élasticité du bouchon donc un retard à retrouver sa forme initiale, sont le siège d'une rétention de vin qui sont sources d'amorces de fuite et de pertes d'étanchéité.Furthermore, the prior compression of the plug is a source of defects in the outer surface of the plug which cooperates, with the inner surface of the neck, to the sealing of the closure. There may then be small cavities which, combined with a hysteresis of the elasticity of the cork, thus a delay in recovering its initial shape, are the seat of a retention of wine which are sources of leakage primers and losses of seal.

Dans des solutions de bouchage alternatives au bouchon liège, habituellement utilisées pour les liquides effervescents, l'étanchéité est obtenue par la compression d'un joint sur la surface supérieure du goulot. La qualité de l'étanchéité dépend du taux de compression de ce joint et de la qualité des surfaces d'appui. Ce sont notamment le bouchage mécanique, la capsule couronne ou le bouchage a vis, techniques rencontrées sur les marchés de la bière et des boissons carbonatées. Dans le cas d'un bouchon à tête maintenu en place par un muselet, l'enfoncement du bouchon dans le col est conditionné principalement par les dimensions des pattes du muselet. Or le mode de réalisation du muselet n'autorise pas de précision élevée des dimensions et des variations importantes de longueur de ces dites pattes sont constatées d'un muselet à l'autre. On comprend qu'avec un tel dispositif, la compression d'un éventuel joint placé entre l'épaulement de la tête du bouchon et le buvant de la bague ne peut pas être assurée de façon régulière et maîtrisée.In alternative cork stopper solutions, usually used for effervescent liquids, sealing is achieved by compressing a seal on the upper surface of the neck. The quality of the seal depends on the compression ratio of this seal and the quality of the bearing surfaces. These include mechanical clogging, crown caps or screw caps, techniques encountered in the beer and carbonated beverage markets. In the case of a cap with a head held in place by a wire cap, the depression of the plug in the neck is mainly conditioned by the dimensions of the legs of the muzzle. However, the embodiment of the muzzle does not allow high precision dimensions and significant variations in length of these legs are found from one wire to the other. It is understood that with such a device, the compression of a possible seal placed between the shoulder of the cap head and the rim of the ring can not be provided in a regular and controlled manner.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Le bouchage traditionnel des bouteilles de vins effervescents et de champagne n'étant plus satisfaisant, il existe un besoin d'un bouchage efficace et de longue durée qui, surtout, ne bouscule pas l'image traditionnelle de l'appellation d'origine que les producteurs entretiennent auprès du consommateur.Since traditional bottling of sparkling wine and champagne bottles is no longer satisfactory, there is a need for effective and long-lasting corking which, above all, does not overturn the traditional image of the appellation of origin that producers maintain with the consumer.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

Ce besoin est satisfait grâce à l'invention qui concerne un bouchon pour bouteille de boisson gazeuse, destiné à coopérer avec le col de la bouteille au moyen d'un muselet de retenue, le bouchon comportant une tête extérieure au buvant du col, une partie de guidage du bouchon dans le col, issue de la tête, au moins un joint latéral rapporté dans une gorge de la partie de guidage pour coopérer par appui étanche avec la surface intérieure du col, la tête comportant en outre une jupe de révolution autour de l'axe de la partie de guidage, s'étendant pour coiffer le buvant du col et être encore au contact de la surface extérieure de ce dernier quand le bouchon est retenu en place par le muselet, par une partie sensiblement cylindrique à l'opposé de la tête au voisinage de son bord libre.This need is satisfied by the invention which relates to a plug for a soft drink bottle, intended to cooperate with the neck of the bottle by means of a retaining muselet, the stopper comprising an external head at the rim of the neck, a guiding portion of the stopper in the neck, issuing from the head, at least one lateral seal attached in a groove of the guiding portion to cooperate by sealing with the inner surface of the neck, the head further comprising a skirt of revolution about the axis of the guide portion, extending to cap the rim of the neck and still be in contact with the outer surface of the latter when the cap is held in place by the muselet, a substantially cylindrical portion opposite the head in the vicinity of its free edge.

Ainsi, la structure du bouchon de l'invention permet de prendre en considération les dispersions dimensionnelles des muselets pour assurer une bonne étanchéité du bouchage.Thus, the structure of the plug of the invention makes it possible to take into consideration the dimensional dispersions of the wire straps to ensure a good sealing of the plugging.

La jupe est sensiblement cylindrique dans sa partie opposée à la tête au voisinage de son bord libre. Cette géométrie permet justement d'autoriser un mouvement entre le bouchon et le goulot de la bouteille, qui se produit après l'enfoncement du bouchon au moment où l'on relâche ce dernier, le muselet ayant été posé, ce tout en conservant ce contact entre la jupe et la surface extérieure du buvant.The skirt is substantially cylindrical in its opposite portion to the head in the vicinity of its free edge. This geometry allows precisely to allow movement between the cap and the neck of the bottle, which occurs after the depression of the cap at the moment when it is released, the muselet having been placed, while maintaining this contact between the skirt and the outer surface of the rim.

De manière traditionnelle la tête est dimensionnée pour avoir une partie périphérique qui se trouve à l'aplomb du buvant, cette partie formant ainsi une butée à l'enfoncement du bouchon dans le col située au fond de la jupe susdite. Dans une réalisation particulière, cette tête possède une partie centrale sensiblement cylindrique et une coque périphérique reliée à la partie centrale par des nervures radiales dont l'extrémité inférieure constitue la butée susdite.In the traditional way the head is dimensioned to have a peripheral portion which is in line with the rim, this part thus forming a stop at the depression of the plug in the neck located at the bottom of the aforesaid skirt. In a particular embodiment, this head has a substantially cylindrical central portion and a peripheral shell connected to the central portion by radial ribs whose lower end constitutes the above abutment.

Il est avantageux de réaliser une partie de guidage comportant au-delà du joint latéral par rapport à la tête, une portion en matériau différent de celui de la tête. Dans cette réalisation, la portion susdite de la partie de guidage est rapportée à l'extrémité de la partie centrale de la tête et délimite avec cette dernière un logement périphérique pour le joint latéral. Ainsi, la forme de ce logement peut-elle être une simple gorge circulaire ou affecter une forme plus complexe comme une rainure ondulée en surface de la partie de guidage. Dans ce cas certains sommets de cette ondulation quittent en premier le col, au moment du débouchage et autorisent une décompression contrôlée ou progressive de l'intérieur de la bouteille.It is advantageous to make a guide portion having beyond the lateral seal relative to the head, a portion of material different from that of the head. In this embodiment, the aforesaid portion of the guide portion is attached to the end of the central portion of the head and delimits with the latter a peripheral housing for the lateral joint. Thus, the shape of this housing can it be a simple circular groove or affect a more complex shape such as a corrugated groove on the surface of the guide portion. In this case, certain peaks of this wave first leave the neck at the time of unblocking and allow controlled or progressive decompression of the inside of the bottle.

Cette mise en oeuvre de deux matériaux permet, dans une version luxueuse de l'invention, de réaliser la tête en verre ou en matériau plastique transparent (polyester) tandis que la partie de guidage sera en une autre matière, rapportée sous la tête. Cette autre matière, notamment plastique, présentera d'excellentes propriétés barrière à l'égard des constituants du vin contenu dans la bouteille.This implementation of two materials allows, in a luxurious version of the invention, to achieve the head of glass or transparent plastic material (polyester) while the guide portion will be in another material, reported under the head. This other material, in particular plastic, will have excellent barrier properties with respect to the constituents of the wine contained in the bottle.

De manière préférée, la portion susdite est tubulaire avec une cloison transversale tandis que sa paroi est encochée du côté de son bord libre, à l'opposé de cette cloison.Preferably, the aforesaid portion is tubular with a transverse partition while its wall is notched on the side of its free edge, opposite this partition.

Pour mieux soutenir l'effort du muselet sur le bouchon, la surface extérieure de la tête possède des rainures d'indexation de la position des pattes du muselet au droit des nervures radiales.To better support the force of the cap on the cap, the outer surface of the head has indexing grooves of the position of the legs of the muzzle to the right of the radial ribs.

Par ailleurs, la tête est pourvue à son sommet d'un logement de réception d'une capsule de personnalisation du bouchage. Dans ce cas, le muselet peut être dépourvu de capsule.In addition, the head is provided at its top with a receptacle for receiving a personalization cap closure capsule. In this case, the muzzle may be devoid of capsule.

Enfin, la partie de guidage comporte au moins une rainure de dégazage de la bouteille aboutissant dans la gorge du joint permettant une décompression progressive de l'intérieur de la bouteille en cours d'ouverture et évitant l'expulsion incontrôlée du bouchon.Finally, the guide portion comprises at least one degassing groove of the bottle ending in the throat of the seal allowing a gradual decompression of the inside of the bottle during opening and avoiding the uncontrolled expulsion of the cap.

D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit de modes de réalisation particuliers non limitatifs de l'invention.Other characteristics and advantages of the invention will emerge on reading the following description of particular non-limiting embodiments of the invention.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Le bouchon représenté à la figure 1 comporte une tête 1 réalisée en matériau, par exemple plastique adapté à toutes les variations de décoration souhaitées. A cet égard on peut utiliser des matériaux tels que les thermoplastiques (polyesters par exemple), du verre, du bois ou du métal. Cette tête est ici représentée creuse et peut comporter des gravures soit sur sa face extérieure 1a soit sur sa face intérieure 1b. Dans ce dernier cas la tête est en matériau transparent. Cette tête peut être réalisée par moulage, par pressage, par usinage et ce, en fonction des matériaux utilisés.The plug shown in figure 1 comprises a head 1 made of material, for example plastic adapted to all the desired decoration variations. In this respect it is possible to use materials such as thermoplastics (for example polyesters), glass, wood or metal. This head is shown here hollow and may include prints either on its outer face 1a or on its inside 1b. In the latter case the head is made of transparent material. This head can be made by molding, by pressing, by machining and this, depending on the materials used.

Elle comporte une partie centrale cylindrique 2, pourvue en partie basse d'un bourrelet intérieur 3 et entourée d'une coque périphérique 4 reliée à la partie centrale cylindrique par son sommet.It comprises a central cylindrical portion 2, provided in the lower part of an inner bead 3 and surrounded by a peripheral shell 4 connected to the central cylindrical portion by its top.

La coque périphérique 4 est terminée en partie basse par une jupe de révolution 5 cylindrique dont le diamètre intérieur est sensiblement égal à celui extérieur d'un buvant 6 de col 7 de bouteille comme représenté aux figures 2 et 3. Ainsi, la partie centrale 2 de la tête constitue-t-elle une partie de guidage du bouchon dans le col de la bouteille alors que la jupe 5 vient coiffer le buvant de ce col en étant au contact de la surface extérieure de ce dernier. Cette fonction est assez simple à assurer car le col d'une bouteille est, en verrerie, bien maîtrisé du point de vue des dimensions et de leurs tolérances. La hauteur de la jupe 5 est de l'ordre de 3 à 4 millimètres afin qu'elle reste toujours au contact du col malgré la remontée (de l'ordre de quelques millimètres) du bouchon, qui s'opère sous l'effet de la pression après la pose du muselet.The peripheral shell 4 is terminated at the bottom by a skirt of cylindrical revolution whose inside diameter is substantially equal to that outside of a bottle mouth 7 6 as shown in FIGS. Figures 2 and 3 . Thus, the central portion 2 of the head is a guiding portion of the plug in the neck of the bottle while the skirt 5 is to cap the rim of the neck in contact with the outer surface of the latter. This function is quite simple to ensure because the neck of a bottle is, in glassware, well mastered from the point of view of dimensions and their tolerances. The height of the skirt 5 is of the order of 3 to 4 millimeters so that it always remains in contact with the neck despite the ascent (of the order of a few millimeters) of the plug, which operates under the effect of the pressure after the installation of the muzzle.

La partie centrale 2 de la tête 1 est prolongée par une portion 8 rapportée à son extrémité pour constituer avec la totalité de la partie de guidage du bouchon. Cette portion 8 est ici tubulaire avec une cloison transversale 9 la divisant en une première partie 8a pour sa fixation par encliquetage à l'extrémité de la partie 2 de la tête, grâce à la coopération du bourrelet 3 avec une gorge 10 et une deuxième partie 8b en forme de paroi tubulaire pourvue d'entailles 11.The central portion 2 of the head 1 is extended by a portion 8 attached at its end to form with the entire guide portion of the plug. This portion 8 is here tubular with a transverse partition 9 dividing it into a first portion 8a for its fastening snap at the end of the part 2 of the head, thanks to the cooperation of the bead 3 with a groove 10 and a second part 8b in the form of a tubular wall provided with notches 11.

La portion 8 de la partie de guidage définit, lorsqu'elle est assemblée à la partie centrale 2 de la tête, avec cette partie centrale, une gorge 12 qui peut recevoir un élément d'étanchéité, par exemple un joint torique 13. La gorge 12 est ici annulaire. Elle peut affecter une forme ondulée de réalisation très simple puisque les flancs de la gorge sont portés par deux pièces axialement assemblées. Ce montage présente l'avantage de faciliter la mise en place du joint.The portion 8 of the guide portion defines, when assembled to the central portion 2 of the head, with this central portion, a groove 12 which can receive a sealing member, for example an O-ring 13. The throat 12 is here annular. It can affect a very simple wave form of realization since the sides of the groove are carried by two axially assembled parts. This arrangement has the advantage of facilitating the establishment of the seal.

Dans le mode de réalisation représenté à la figure 1, le col de la bouteille pénètre entre la coque 3 et la partie de guidage 2 sans rencontrer de butée positive à l'enfoncement. Le bouchage doit dans ces conditions être parfaitement contrôlé en ce qui concerne la position relative du col et du bouchon lors de l'enfoncement.In the embodiment shown at figure 1 , the neck of the bottle enters between the shell 3 and the guide portion 2 without encountering a positive stop at the depression. Clogging must in these conditions be perfectly controlled with respect to the relative position of the neck and the plug during the depression.

La réalisation représentée aux figures 2 et 3 fait apparaître entre la partie 2 et la coque 4 des nervures radiales 14 qui, d'une part rigidifient la tête et d'autre part, par leur bord inférieur 14a, formes une butée de contrôle de l'enfoncement au bouchage en venant prendre appui sur la surface supérieure du buvant 6. La position relative du col et du bouchon à la figure 2 est celle lors de la pose du muselet tandis qu'à la figure 3 elle correspond à la position finale prise sous l'effet de la pression existant dans la bouteille.The achievement represented Figures 2 and 3 reveals between the portion 2 and the shell 4 radial ribs 14 which, on the one hand stiffen the head and on the other hand, by their lower edge 14a, forms a stop of control of the depression at the stopper by coming to bear on the upper surface of the rim 6. The relative position of the collar and cork at the figure 2 is the one when laying the muzzle while at the figure 3 it corresponds to the final position taken under the effect of the pressure existing in the bottle.

Une ou plusieurs rainures de décompression 15 sont ménagées le long d'une génératrice de la portion 8b depuis son extrémité libre jusque dans la gorge 12. Cette rainure est le canal d'une fuite de décompression de la bouteille lorsque, au desserrage du muselet, le bouchon remonte progressivement le long du col jusqu'à ce que le joint torique passe au niveau du buvant permettant au gaz de s'échapper sans brutalité. La pression à l'intérieur du récipient baisse et s'équilibre avec la pression atmosphérique. La force d'expulsion qui s'exerçait sur le bouchon devient nulle, la partie 8b, située sous la gorge 12 et qui est d'un diamètre légèrement supérieur au diamètre intérieur du goulot, freine le bouchon et celui-ci est stoppé dans sa course. L'ouverture totale de la bouteille sera alors réalisée facilement et sous contrôle du consommateur par un mouvement de rotation et traction.One or more decompression grooves 15 are formed along a generatrix of the portion 8b from its free end into the groove 12. This groove is the channel of a decompression leak of the bottle when, loosening the muzzle, the cap rises gradually along the neck until the O-ring passes to the level of the rim allowing the gas to escape without brutality. The pressure inside the container drops and equilibrates with the atmospheric pressure. The force of expulsion which was exerted on the plug becomes zero, the part 8b, located under the groove 12 and which is of a diameter slightly greater than the inside diameter of the neck, brakes the plug and it is stopped in its race. The total opening of the bottle will then be carried out easily and under control of the consumer by a rotational movement and traction.

Cet effet de décompression peut également être obtenu par la mise en place d'un joint ondulé comme mentionné ci-dessus.This decompression effect can also be achieved by placing a corrugated seal as mentioned above.

Un muselet 16 est également représenté aux figures 2 et 3. La coque 4 du bouchon peut être pourvue de rainures 17 dans lesquelles viennent se loger les pattes 16a du muselet 16. Ces rainures seront situées au droit des nervures radiales 14 afin d'encaisser l'effort de serrage du muselet. Ce muselet pourra être un muselet sans capsule supérieure, celle-ci 19 ayant été préalablement mise en place dans le logement 18 du sommet du bouchon rapportée ce qui rend plus souple la personnalisation de la bouteille.A muselet 16 is also shown to Figures 2 and 3 . The shell 4 of the plug may be provided with grooves 17 in which are housed the tabs 16a of the muelet 16. These grooves will be located in line with the radial ribs 14 in order to cash the clamping force of the muzzle. This cap may be a cap without upper capsule, the latter 19 having been previously put in place in the housing 18 of the top of the plug reported which makes the customization of the bottle more flexible.

On peut, bien entendu, avec le bouchon de l'invention, mettre en place un muselet traditionnel avec sa plaque de personnalisation débordant sous le cercle supérieur du muselet.We can, of course, with the plug of the invention, set up a traditional muselet with his personalization plate overflowing under the upper circle of the muzzle.

Claims (9)

  1. A stopper for an aerated beverage bottle, the stopper being designed to co-operate with the neck of the bottle by means of a retaining cap, the stopper comprising a head (1) outside the rim (6) of the neck (7), and a guide portion (2, 8) extending from the head for guiding the stopper in the neck, the stopper being characterized in that it includes at least one lateral sealing ring (13) fitted in a groove of the guide portion to co-operate with the inside surface of the neck by bearing thereagainst in leaktight manner, and a skirt (4) in the form of a body of revolution about the axis of the guide portion (2, 8) extending to cover the rim (6) of the neck (7) while being in contact with the outside surface thereof and also being in contact therewith when the stopper is held in place by the retaining cap (16), contact being via a substantially cylindrical portion remote from the head and in the vicinity of the free edge of the skirt.
  2. A stopper according to claim 1, characterized in that the head (1) is dimensioned to have a peripheral portion overlying the rim (6), this portion thus forming an abutment opposing the stopper being pushed into the neck, the abutment being situated at the end of the said skirt.
  3. A stopper according to claim 2, characterized in that the head (1) possesses a central portion (2) that is substantially cylindrical and a peripheral shell (3) that is connected to the central portion by radial webs (14) having bottom ends (14a) constituting the said abutment.
  4. A stopper according to any preceding claim, characterized in that the guide portion (2, 8) includes, beyond the lateral sealing ring (13) going away from the head (1): a fitting (8) fitted to the end of the central portion (2) of the head and co-operating therewith to define a peripheral housing (12) for the lateral sealing ring (13).
  5. A stopper according to claim 4, characterized in that the said fitting (8) of the guide portion is made of a material that is different from the material of the head (1).
  6. A stopper according to claim 4 or claim 5, characterized in that the said fitting (8) is tubular with a transverse partition (9), while its wall has notches (11) extending away from the partition (9) to the free edge of the fitting.
  7. A stopper according to claim 1, characterized in that the outside surface (1a) of the head (1) possesses grooves (17) for indexing the positions of tabs (16a) of the cap (16) in register with the radial webs (14).
  8. A stopper according to any preceding claim, characterized in that the head is provided at its top with a housing (18) for receiving a personalizing crown and seal.
  9. A stopper according to any preceding claim, characterized in that the guide portion (2, 8) includes at least one groove (15) for degassing the bottle and terminating in the housing (12) for the sealing ring (13), thereby enabling the pressure inside the bottle to be reduced progressively during opening.
