Description

La présente invention concerne un dispositif de bouchage temporaire pour des bouteilles destinées à contenir plus particulièrement, quoique non exclusivement, un vin de champagne ou analogue.The present invention relates to a temporary corking device for bottles intended to contain more particularly, although not exclusively, a champagne wine or the like.

On sait que pour obtenir un vin de champagne ayant toutes les qualités requises, plusieurs phases et/ou traitements, s'étalant sur plusieurs années, sont nécessaires entre sa mise en bouteille et sa mise en vente sur le marché.We know that to obtain a champagne wine having all the required qualities, several phases and / or treatments, spanning several years, are necessary between its bottling and its sale on the market.

Ainsi, dans la phase d'élaboration du vin, dite de tirage, on utilise, selon la méthode champenoise, un dispositif de bouchage temporaire, double, c'est-à-dire constitué d'un obturateur et d'une capsule de bouchage. Plus particulièrement, l'obturateur, dénommé également "cartouche" par les professionnels, est réalisé en une matière synthétique et présente une forme cylindrique creuse, apte à s'engager à force dans l'ouverture du col de la bouteille jusqu'à ce qu'une saillie annulaire d'une paroi transversale, obturant l'extrémité opposée à celle s'engageant dans l'ouverture, vienne en butée axiale contre une partie correspondante de la face d'extrémité annulaire du col. La capsule métallique maintient par la suite l'obturateur ainsi enfoncé par l'intermédiaire d'une garniture d'étanchéité en liège, sous forme de disque, prévue sur le fond interne de la capsule et s'appliquant contre la face d'extrémité annulaire du col et contre la paroi transversale de l'obturateur. La périphérie latérale de la capsule est, pour cela, sertie sur un rebord annulaire externe dudit col, ce qui assure la fixation du dispositif de bouchage temporaire.Thus, in the wine-making phase, known as the draft, we use, according to the Champagne method, a temporary, double corking device, that is to say consisting of a shutter and a corking capsule. . More particularly, the shutter, also called "cartridge" by professionals, is made of a synthetic material and has a hollow cylindrical shape, able to forcefully engage in the opening of the neck of the bottle until 'An annular projection of a transverse wall, closing the opposite end to that engaging in the opening, comes into axial abutment against a corresponding part of the annular end face of the neck. The metal capsule subsequently holds the shutter thus inserted by means of a cork seal, in the form of a disc, provided on the internal bottom of the capsule and pressing against the annular end face. from the neck and against the transverse wall of the obturator. The lateral periphery of the capsule is, for this, crimped onto an external annular rim of said neck, which ensures the fixing of the temporary closure device.

Ces dispositifs doivent alors garantir une étanchéité parfaite pendant le temps de leur mise en place sur les bouteilles, qui atteint généralement deux années, tout en résistant à la pression interne, comprise entre 6 et 7 bars, des gaz qui prennent naissance au sein du liquide contenu dans les bouteilles. Ensuite, on procède à la phase dite de dégagement qui consiste à retirer ladite capsule pour libérer le gaz engendré, expulsant l'obturateur.These devices must then guarantee a perfect seal during the time of their installation on the bottles, which generally reaches two years, while resistant to internal pressure, between 6 and 7 bars, of gases which arise within the liquid contained in the bottles. Then, we proceed to the so-called release phase which consists in removing said capsule to release the generated gas, expelling the shutter.

Toutefois, il arrive que ces dispositifs de bouchage perdent de leur efficacité en entraînant l'apparition de fuite et/ou de suintement du liquide, contenu dans les bouteilles, vers l'extérieur. Cela est essentiellement dû à la garniture d'étanchéité en liège qui, à cause de la pression élevée s'exerçant sur la paroi transversale de l'obturateur et, donc, sur celle-ci, et de la durée de mise en place, peut se déformer et se dégrader, en raison de ses caractéristiques mécaniques, notamment de tenue à la pression, insuffisantes. Par conséquent, l'étanchéité n'est pas toujours totalement assurée.However, it sometimes happens that these closure devices lose their effectiveness by causing the appearance of leakage and / or seepage of the liquid, contained in the bottles, towards the outside. This is mainly due to the cork gasket which, due to the high pressure exerted on the transverse wall of the shutter and therefore on it, and the duration of installation, can deform and degrade, due to its insufficient mechanical properties, in particular resistance to pressure. Consequently, the seal is not always fully guaranteed.

La présente invention a pour but de remédier à ces inconvénients et concerne un dispositif de bouchage temporaire pour bouteilles permettant d'améliorer le maintien en position dudit obturateur et l'étanchéité vis-à-vis de l'extérieur.The present invention aims to remedy these drawbacks and relates to a temporary corking device for bottles making it possible to improve the holding in position of said shutter and the seal against the outside.

A cet effet, le dispositif de bouchage temporaire pour bouteilles contenant un vin de champagne ou analogue, du type comportant :

  • un obturateur cylindrique, apte à être engagé à force dans l'ouverture du col de la bouteille et obturé par une paroi transversale à saillie annulaire venant en butée axiale contre la face d'extrémité annulaire dudit col ; et,
  • une capsule de bouchage dont la périphérie est destinée à être sertie sur un rebord annulaire externe dudit col, et contre le fond interne de laquelle est prévue une garniture d'étanchéité apte à s'appliquer contre ladite face annulaire du col et contre la paroi transversale dudit obturateur,
est remarquable, selon l'invention, en ce que ladite garniture d'étanchéité est réalisée en une matière synthétique et en ce qu'elle comprend au moins une lèvre annulaire d'étanchéité apte à s'appliquer contre la face d'extrémité annulaire dudit col, et une pluralité de picots aptes à s'appliquer contre la paroi transversale dudit obturateur.To this end, the temporary corking device for bottles containing a champagne wine or the like, of the type comprising:
  • a cylindrical shutter, capable of being forcibly engaged in the opening of the neck of the bottle and closed by a transverse wall with an annular projection coming into axial abutment against the annular end face of said neck; and,
  • a closure cap, the periphery of which is intended to be crimped onto an external annular rim of said neck, and against the internal bottom of which is provided a seal suitable for applying against said annular face of the neck and against the transverse wall said shutter,
is remarkable, according to the invention, in that said seal is made of a synthetic material and in that it comprises at least one annular sealing lip capable of being applied against the annular end face of said neck, and a plurality of pins capable of being applied against the transverse wall of said shutter.

Ainsi, grâce à la nature de la garniture d'étanchéité, en matière synthétique, qui est moins sujette aux déformations et, donc, à la pression exercée sur l'obturateur, qu'une garniture en liège, et à la présence d'une lèvre annulaire pour garantir l'étanchéité et de picots pour maintenir en position ledit obturateur, on réalise un dispositif de bouchage temporaire ayant les caractéristiques mécaniques requises pour résister à la pression interne et éviter les risques de fuite et/ou de suintement.Thus, thanks to the nature of the seal, made of synthetic material, which is less subject to deformation and, therefore, to the pressure exerted on the shutter, than a cork seal, and to the presence of a annular lip to guarantee the tightness and of pins to maintain in position said obturator, a temporary closure device is produced having the mechanical characteristics required to resist the internal pressure and to avoid the risks of leakage and / or seepage.

De préférence, ladite garniture comprend une lèvre annulaire d'étanchéité additionnelle, concentrique à la précédente et apte à s'appliquer contre la face d'extrémité annulaire dudit col. On parfait ainsi l'étanchéité puisqu'elle est obtenue par le contact des deux lèvres sur la face annulaire terminant le col de la bouteille. Avantageusement, les deux lèvres annulaires concentriques forment entre elles un V ou analogue de façon que, lorsque ladite capsule de bouchage est sertie, les bords libres desdites lèvres s'écrasent sur la quasi-totalité de la face annulaire d'extrémité dudit col. Ainsi, l'étanchéité réalisée est optimale puisque les bords écrasés des lèvres arrivent jusqu'au voisinage respectivement de la saillie annulaire dudit obturateur et du rebord annulaire externe.Preferably, said lining comprises an additional annular sealing lip, concentric with the previous one and capable of being applied against the annular end face of said neck. The seal is thus perfected since it is obtained by the contact of the two lips on the annular face ending the neck of the bottle. Advantageously, the two concentric annular lips form between them a V or the like so that, when said closure cap is crimped, the free edges of said lips are crushed over almost the entire annular end face of said neck. Thus, the seal produced is optimal since the crushed edges of the lips arrive up to the vicinity respectively of the annular projection of said obturator and of the external annular rim.

Par ailleurs, lesdits picots peuvent être disposés selon une même circonférence, de façon équi-angulairement répartie les uns par rapport aux autres. Plus particulièrement, lesdits picots sont alors situés sur une circonférence proche de ladite lèvre annulaire, de façon qu'ils s'appliquent sur la saillie annulaire dudit obturateur, elle-même en butée contre la partie correspondante de la face annulaire d'extrémité dudit col. On réalise ainsi un maintien efficace dudit obturateur enfoncé, reprenant au mieux la pression interne.Furthermore, said pins can be arranged according to the same circumference, in an equi-angular manner distributed with respect to each other. More particularly, said pins are then located on a circumference close to said annular lip, so that they are applied to the annular projection of said obturator, itself in abutment against the corresponding part of the annular end face of said neck. This effectively maintains said shutter depressed, taking up internal pressure as best as possible.

The figures of the appended drawing will make it clear how the invention can be implemented. In these figures, identical references designate similar elements.
  • Figure 1 shows, in exploded axial section, an embodiment of said temporary closure device according to the invention, before its introduction into the neck of a bottle.
  • Figure 2 is a bottom view of said closure cap showing said seal.
  • FIG. 3 represents, on an enlarged scale and in axial half-section, the closure device after its installation in the neck of said bottle.

Le dispositif de bouchage temporaire 1, illustré sur la figure 1 et conforme à l'invention, est destiné à être monté dans l'ouverture cylindrique 2A du col 2B d'une bouteille 2 contenant un vin de champagne. Pour cela, le dispositif 1 se compose d'un obturateur cylindrique 3 pour l'ouverture 2A de la bouteille, et d'une capsule de bouchage 4 pour le maintien en position de l'obturateur 3 par sertissage sur un rebord annulaire externe 2C dudit col.The temporary closure device 1, illustrated in FIG. 1 and in accordance with the invention, is intended to be mounted in the cylindrical opening 2A of the neck 2B of a bottle 2 containing a champagne wine. For this, the device 1 consists of a cylindrical shutter 3 for the opening 2A of the bottle, and a closure cap 4 for holding the shutter 3 in position by crimping on an external annular rim 2C of said collar.

Plus particulièrement, l'obturateur 3 est réalisé en une matière synthétique, par exemple en un polyéthylène, et il comprend une jupe latérale cylindrique 3A qui est obturée par une paroi transversale 3B à saillie annulaire 3C à son extrémité 3D opposée à l'extrémité ouverte conique 3E destinée à s'engager dans l'ouverture 2A dudit col de bouteille. Dimensionnellement, le diamètre externe de la jupe latérale 3A à section annulaire est au moins égal, de préférence légèrement supérieur, à celui de l'ouverture 2A. La saillie annulaire 3C de la paroi 3B a pour but de venir en butée axiale contre la face d'extrémité annulaire 2D du col pour limiter l'introduction de l'obturateur 3 dans l'ouverture 2A de la bouteille. Pour cela, le diamètre de la saillie annulaire 3C est déterminé pour s'appliquer sur une partie annulaire 2D1 de ladite face d'extrémité 2D, comprenant également le bord arrondi 2E reliant celle-ci à la paroi interne 2F qui délimite l'ouverture 2A dudit col.More particularly, the shutter 3 is made of a synthetic material, for example a polyethylene, and it comprises a cylindrical side skirt 3A which is closed by a transverse wall 3B with annular projection 3C at its 3D end opposite the open end conical 3E intended to engage in the opening 2A of said neck bottle. Dimensionally, the external diameter of the lateral skirt 3A with annular section is at least equal, preferably slightly greater, than that of the opening 2A. The purpose of the annular projection 3C of the wall 3B is to come into axial abutment against the 2D annular end face of the neck to limit the introduction of the shutter 3 into the opening 2A of the bottle. For this, the diameter of the annular projection 3C is determined to be applied to an annular part 2D1 of said end face 2D, also comprising the rounded edge 2E connecting the latter to the internal wall 2F which delimits the opening 2A of said pass.

Par ailleurs, un renfoncement central 3F est ménagé dans la paroi transversale 3B pour permettre à un outil de poinçonnage, non représenté, d'enfoncer l'obturateur 3 dans l'ouverture 2A du col de la bouteille 2.Furthermore, a central recess 3F is formed in the transverse wall 3B to allow a punching tool, not shown, to push the shutter 3 into the opening 2A of the neck of the bottle 2.

La capsule de bouchage 4 est, quant à elle, métallique et elle comporte usuellement une paroi latérale périphérique crénelée 4A, destinée à être sertie sur un rebord annulaire externe 2C du col, qui prolonge la face annulaire d'extrémité transversale 2D de la bouteille. Le fond 4B de la capsule est pourvu, sur sa face interne 4C, d'une garniture d'étanchéité 5 apte à venir s'appliquer à la fois contre la face annulaire 2D du col de bouteille et contre la paroi transversale 3B à saillie annulaire 3C de l'obturateur.The closure cap 4 is metallic, and it usually comprises a crenellated peripheral lateral wall 4A, intended to be crimped on an external annular rim 2C of the neck, which extends the annular face of 2D transverse end of the bottle. The bottom 4B of the capsule is provided, on its internal face 4C, with a seal 5 capable of coming to be applied both against the 2D annular face of the bottle neck and against the transverse wall 3B with annular projection 3C of the shutter.

Avantageusement, cette garniture d'étanchéité 5 est réalisée en une matière synthétique et elle présente une forme circulaire dont le diamètre correspond sensiblement à celui du fond 4B de la capsule et, par conséquent, à celui de la face d'extrémité annulaire 2D de la bouteille.Advantageously, this seal 5 is made of a synthetic material and it has a circular shape whose diameter corresponds substantially to that of the bottom 4B of the capsule and, consequently, to that of the 2D annular end face of the bottle.

Dans cet exemple préféré de réalisation, la garniture 5 comprend plus particulièrement deux lèvres annulaires d'étanchéité, concentriques 5A et 5B, situées à proximité de sa périphérie, pour venir s'appliquer par leurs bords libres 5A1 et 5B1 contre la face d'extrémité annulaire 2D. On voit notamment sur la figure 1, que les deux lèvres 5A et 5B s'éloignent l'une de l'autre en divergeant, pour former entre elles un V renversé. Ainsi, le bord libre 5A1 de la lèvre d'étanchéité externe 5A se dirige vers l'extérieur, c'est-à-dire vers la périphérie crénelée 4A de la capsule, tandis que le bord libre 5B1 de la lèvre d'étanchéité interne 5B se dirige vers l'intérieur.In this preferred embodiment, the lining 5 more particularly comprises two annular sealing lips, concentric 5A and 5B, located near its periphery, to be applied by their free edges 5A1 and 5B1 against the 2D annular end face. It can be seen in particular in FIG. 1 that the two lips 5A and 5B move away from each other by diverging, to form an inverted V between them. Thus, the free edge 5A1 of the external sealing lip 5A is directed towards the outside, that is to say towards the crenellated periphery 4A of the capsule, while the free edge 5B1 of the internal sealing lip 5B heads inward.

Par ailleurs, comme le montrent les figures 1 et 2, la garniture d'étanchéité 5 est munie d'une pluralité de picots 5C aptes à s'appliquer contre l'obturateur 3. Ces picots 5C font bien entendu saillie de la garniture du même côté que les lèvres concentriques 5A, 5B et présentent une forme identique, légèrement arrondie. On prévoit dans cet exemple six picots 5C équi-angulairement répartis les uns par rapport aux autres sur une même circonférence, proche de la lèvre 5B, pour venir s'appliquer ponctuellement sur la saillie annulaire 3C de l'obturateur 3. On remarque également que la hauteur desdites lèvres d'étanchéité 5A et 5B est supérieure à la somme de la hauteur desdits picots et de l'épaisseur de ladite saillie annulaire, pour permettre un écrasement convenable de ceux-ci sur la face d'extrémité 2D.Furthermore, as shown in FIGS. 1 and 2, the seal 5 is provided with a plurality of pins 5C capable of being applied against the shutter 3. These pins 5C obviously protrude from the seal of the same side that the concentric lips 5A, 5B and have an identical shape, slightly rounded. In this example, six pins 5C are provided which are equiangularly distributed with respect to each other on the same circumference, close to the lip 5B, in order to be applied punctually on the annular projection 3C of the shutter 3. It is also noted that the height of said sealing lips 5A and 5B is greater than the sum of the height of said pins and the thickness of said annular projection, to allow suitable crushing of these on the 2D end face.

La mise en place du dispositif de bouchage temporaire 1 s'effectue en engageant axialement l'obturateur 3 dans l'ouverture 2A de la bouteille. Pour cela, sous l'action de l'outil de poinçonnage, la jupe latérale cylindrique 3A coulisse le long de la paroi 2F délimitant l'ouverture 2A, jusqu'à ce que la saillie annulaire 3C de la paroi transversale 3B vienne en butée contre la partie correspondante 2D1 de ladite face annulaire d'extrémité 2D du col 2B. La capsule de bouchage 4 est ensuite montée de façon que, lors de l'opération de sertissage solidarisant la périphérie crénelée 4A de la capsule avec le rebord annulaire externe 2C du col, les bords libres 5A1 et 5B1 des lèvres concentriques 5A et 5B s'écrasent par déformation élastique contre la face annulaire d'extrémité 2D, et que les picots 5C s'appliquent énergiquement contre la saillie annulaire 3C dudit obturateur 3.The temporary closure device 1 is put in place by axially engaging the shutter 3 in the opening 2A of the bottle. For this, under the action of the punching tool, the cylindrical side skirt 3A slides along the wall 2F delimiting the opening 2A, until the annular projection 3C of the transverse wall 3B abuts against the corresponding 2D1 part of said annular 2D end face of the neck 2B. The closure cap 4 is then mounted so that, during the crimping operation securing the crenellated periphery 4A of the capsule with the external annular rim 2C of the neck, the free edges 5A1 and 5B1 of the concentric lips 5A and 5B are crushed by elastic deformation against the annular end face 2D, and that the pins 5C are applied energetically against the annular projection 3C of said obturator 3.

Comme le montre la figure 3, on réalise d'une part, une double étanchéité entre le dispositif 1 et l'ouverture 2A de la bouteille, au moyen des deux lèvres concentriques 5A, 5B dont les bords écrasés couvrent la presque totalité de la face annulaire 2D, et d'autre part, un maintien efficace dudit obturateur enfoncé grâce à l'action des picots 5C agissant sur la saillie annulaire 3C, à l'aplomb de la partie 2D1 de la face annulaire 2D. On évite alors, par cette garniture 5, les phénomènes de remontée de l'obturateur 3 sous l'action de la pression interne et les risques de suintement de liquide vers l'extérieur.As shown in Figure 3, there is provided on the one hand, a double seal between the device 1 and the opening 2A of the bottle, by means of the two concentric lips 5A, 5B whose crushed edges cover almost the entire face 2D annular, and secondly, effective maintenance of said shutter pressed through the action of pins 5C acting on the annular projection 3C, directly above the 2D1 part of the 2D annular face. This lining 5 then avoids the phenomena of the shutter 3 rising under the action of internal pressure and the risks of liquid seeping outwards.

Claims (5)

  1. Temporary sealing device for bottles containing a champagne or similar wine, of the type including:
    - a cylindrical stopper (3) able to be forcibly engaged in the opening (2A) of the neck of the bottle and closed off by a transverse wall (3B) with an annular projection (3C) axially abutting against the annular end face (2D) of the said neck; and
    - a sealing cap (4), the periphery of which is intended to be crimped over an external annular rim of the said neck, and against the internal end (4B) of which there is provided a seal (5) able to press against the said annular face (2D) of the neck and against the transverse wall (3B) of the said stopper,
    characterized in that the said seal (5) is made of a synthetic substance and in that it comprises at least one annular sealing lip (5A or 5B) able to press against the annular end face (2D) of the said neck, and a plurality of studs (5C) able to press against the transverse wall of the said stopper.
  2. Device according to Claim 1,
    characterized in that the said seal (5) comprises an additional annular sealing lip (5B or 5A) which is concentric with the previous one and able to press against the annular end face (2D) of the said neck.
  3. Device according to Claim 2,
    characterized in that the two concentric annular lips (5A, 5B) form between them a V or the like so that when the said sealing cap (4) is crimped on, the free edges (5A1, 5B1) of the said lips are crushed onto almost all of the annular end face (2D) of the said neck.
  4. Device according to one of the preceding claims 1 to 3,
    characterized in that the said studs (5C) are arranged on one and the same circumference, so that they are distributed equiangularly with respect to one another.
  5. Device according to Claim 4,
    characterized in that the said studs (5C) are situated on a circumference close to the said annular lip (5B) so that they are pressed onto the annular projection (3C) of the said stopper, itself abutting against the corresponding part (2D1) of the annular end face (2D) of the said neck.
