Description

La présente invention est relative au domaine du bouchage des bouteilles contenant des vins effervescents, ou toutes boissons ou liquides gazeux.The present invention relates to the field of corking bottles containing sparkling wines, or any drinks or carbonated liquids.

Une application particulièrement intéressante de l'invention concerne le bouchage des bouteilles de vins de Champagne.A particularly interesting application of the invention relates to the corking of bottles of Champagne wines.

De tels bouchons pour vins effervescents, de forme initiale sensiblement cylindrique avant bouchage, présentent une partie enfoncée à l'état comprimé dans le col de bouteille dite partie d'obturation et une partie qui dépasse du col de bouteille dite partie de tête.Such stoppers for sparkling wines, of substantially cylindrical initial shape before corking, have a part inserted in the compressed state into the bottle neck called the sealing part and a part which protrudes from the bottle neck called the head part.

Après bouchage, la partie de tête du bouchon reprend sensiblement sa forme initiale alors que la partie d'obturation reste comprimée radialement au diamètre intérieur du col de bouteille. Après débouchage, les bouchons adoptent une forme en champignon caractéristique d'un maintien en bouteille relativement long.After corking, the head part of the stopper substantially returns to its initial shape while the sealing part remains compressed radially to the inside diameter of the bottle neck. After uncorking, the corks adopt a mushroom shape characteristic of a relatively long bottling.

Selon une première conception historique de bouchons pour vins de Champagne, ces bouchons comprennent un corps réalisé en liège naturel et une ou plusieurs rondelles fixées à l'extrémité inférieure de ce corps et réalisées également en liège naturel. De tels bouchons sont appelés généralement bouchons "tout liège".According to a first historical conception of stoppers for Champagne wines, these stoppers comprise a body made of natural cork and one or more washers fixed to the lower end of this body and also made of natural cork. Such stoppers are generally called "all cork" stoppers.

Cependant, de tels bouchons entièrement en liège naturel ne permettent pas d'assurer une bonne obturation du col de bouteille, ce qui peut provoquer l'obtention de bouteilles dites couleuses.However, such stoppers made entirely of natural cork do not make it possible to ensure good sealing of the bottle neck, which can cause so-called pouring bottles to be obtained.

Pour améliorer les propriétés de bouchage, selon une deuxième conception des bouchons, le corps en liège naturel est remplacé par un corps réalisé en liège aggloméré.To improve the corking properties, according to a second design of the corks, the body of natural cork is replaced by a body made of agglomerated cork.

Le corps en liège aggloméré de tels bouchons est composé de granulés de liège naturel liés par de la colle. En outre, des adjuvants peuvent également être ajoutés à ce corps. La colle et les adjuvants sont issus de ressources fossiles, non renouvelables et à forte empreinte carbone.The agglomerated cork body of such stoppers is made of natural cork granules bonded together by glue. In addition, adjuvants can also be added to this body. The glue and adjuvants are derived from fossil resources, non-renewable and with a high carbon footprint.

La présente invention vise à prévoir un bouchon pour vins effervescents, notamment de type Champagne, ou liquide gazeux permettant de réduire la consommation de matières fossiles sans altérer les propriétés de bouchage de la partie d'obturation du bouchon.The present invention aims to provide a stopper for sparkling wines, in particular of the Champagne type, or gaseous liquid making it possible to reduce the consumption of fossil materials without altering the stoppering properties of the sealing part of the stopper.

L'invention concerne un bouchon pour le bouchage d'un col de bouteille de vin effervescent ou de liquide gazeux s'étendant selon un axe longitudinal, et comprenant un corps de bouchon et au moins une rondelle inférieure en liège naturel fixée à une extrémité inférieure dudit corps de bouchon.The invention relates to a stopper for sealing a neck of a bottle of sparkling wine or gaseous liquid extending along a longitudinal axis, and comprising a stopper body and at least one lower washer made of natural cork fixed to a lower end. of said plug body.

Selon une caractéristique générale, le bouchon comprend en outre, fixée à une extrémité supérieure du corps de bouchon, au moins une rondelle supérieure en liège naturel avec un veinage orienté transversalement à l'axe longitudinal dudit bouchon.According to a general characteristic, the stopper further comprises, fixed to an upper end of the stopper body, at least one upper washer of natural cork with a grain oriented transversely to the longitudinal axis of said stopper.

Selon une autre caractéristique générale, le corps de bouchon est en liège naturel avec un veinage orienté selon l'axe longitudinal dudit bouchon.According to another general characteristic, the stopper body is made of natural cork with a grain oriented along the longitudinal axis of said stopper.

On entend par « veinage du liège naturel », les veines correspondant à l'arrêt de croissance des cellules du liège naturel pendant la période hivernale.The term “natural cork veining” is understood to mean the veins corresponding to the stopping of growth of natural cork cells during the winter period.

Par « veinage orienté transversalement à l'axe longitudinal dudit bouchon », on entend que le veinage est orienté selon une direction générale perpendiculaire, ou sensiblement perpendiculaire, à l'axe longitudinal du bouchon.By “grain oriented transversely to the longitudinal axis of said stopper” is meant that the grain is oriented in a general direction perpendicular, or substantially perpendicular, to the longitudinal axis of the stopper.

Par « veinage orienté selon l'axe longitudinal dudit bouchon », on entend que le veinage est orienté selon une direction générale parallèle, ou sensiblement parallèle, à l'axe longitudinal du bouchon.By “grain oriented along the longitudinal axis of said stopper” is meant that the grain is oriented in a general direction parallel, or substantially parallel, to the longitudinal axis of the stopper.

La demanderesse a déterminé que l'orientation du veinage du liège naturel du corps de bouchon combinée à l'orientation du veinage du liège naturel de ladite rondelle supérieure permet d'obtenir une qualité de bouchage similaire à celle des bouchons conventionnels précités avec un corps en liège aggloméré, et améliore aussi sensiblement l'obturation obtenue avec des bouchons "tout liège" existants.The Applicant has determined that the orientation of the veining of the natural cork of the stopper body combined with the orientation of the veining of the natural cork of said upper washer makes it possible to obtain a sealing quality similar to that of the aforementioned conventional corks with a body in agglomerated cork, and also significantly improves the sealing obtained with existing "all cork" stoppers.

L'orientation du veinage du liège de ladite rondelle supérieure permet l'obtention d'une rondelle plus rigide, notamment après l'opération de museletage, ce qui contribue à une meilleure étanchéité sur le buvant du col de bouteille associé.The orientation of the veining of the cork of said upper washer makes it possible to obtain a more rigid washer, in particular after the wire-wrapping operation, which contributes to a better seal on the rim of the associated bottle neck.

Par ailleurs, le bouchon de l'invention est réalisé par assemblage de pièces qui sont réalisées en liège naturel, ce qui diminue fortement la part de matières fossiles.Furthermore, the stopper of the invention is produced by assembling parts which are made of natural cork, which greatly reduces the proportion of fossil materials.

Selon un mode de réalisation particulier, le corps de bouchon est formé d'une pluralité de parties assemblées entre elles et empilées transversalement à l'axe longitudinal dudit bouchon.According to a particular embodiment, the stopper body is formed from a plurality of parts assembled together and stacked transversely to the longitudinal axis of said stopper.

Préférentiellement, le corps de bouchon est formé d'au moins trois parties.Preferably, the stopper body is formed from at least three parts.

La réalisation du corps de bouchon en plusieurs parties, préférentiellement trois, empilées selon un axe transversal est particulièrement avantageuse dans la mesure où cela permet d'assurer une bonne étanchéité dans le sens radial à l'intérieur du col de bouteille associé, même si la qualité du liège naturel d'une des parties du corps de bouchon est moins bonne.The production of the stopper body in several parts, preferably three, stacked along a transverse axis is particularly advantageous insofar as this makes it possible to ensure good sealing in the radial direction inside the associated bottle neck, even if the The quality of the natural cork of one of the parts of the stopper body is less good.

En effet, la ou les autres parties du corps de bouchon qui tendent par élasticité à reprendre leur volume initial en réaction à leur compression radiale à l'intérieur du col de bouteille, agissent radialement sur cette partie du corps de bouchon ce qui favorise le maintien du contact radial entre cette partie et le col de bouteille.Indeed, the other part (s) of the stopper body which tend by elasticity to resume their initial volume in reaction to their radial compression inside the bottle neck, act radially on this part of the stopper body which promotes retention. radial contact between this part and the bottle neck.

De préférence, les parties adjacentes du corps de bouchon sont assemblées entre elles le long d'un plan de fixation parallèle à l'axe longitudinal dudit bouchon. Ceci facilite la fabrication du corps de bouchon.Preferably, the adjacent parts of the stopper body are assembled together along a fixing plane parallel to the longitudinal axis of said stopper. This facilitates the manufacture of the stopper body.

Les parties du corps de bouchon peuvent être assemblées entre elles par collage.The parts of the stopper body can be assembled together by gluing.

Dans un mode de réalisation, le liège naturel de ladite rondelle inférieure présente un veinage orienté transversalement à l'axe longitudinal dudit bouchon.In one embodiment, the natural cork of said lower washer has a veining oriented transversely to the longitudinal axis of said stopper.

Selon un mode de réalisation particulier, la distance H1 séparant une face d'extrémité inférieure de ladite rondelle inférieure d'une interface entre le corps de bouchon et ladite rondelle supérieure est supérieure ou égale à 50 % de la hauteur H totale du bouchon.According to a particular embodiment, the distance H 1 separating a lower end face of said lower washer from an interface between the stopper body and said upper washer is greater than or equal to 50% of the total height H of the stopper.

On entend par « interface entre le corps de bouchon et ladite rondelle supérieure », la zone ou plan de fixation du corps de bouchon avec cette rondelle. Cette fixation peut par exemple être réalisée par collage.The term “interface between the stopper body and said upper washer” is understood to mean the area or plane of attachment of the stopper body to this washer. This fixing can for example be carried out by gluing.

On entend par « face d'extrémité inférieure de ladite rondelle inférieure », la face de la rondelle destinée à venir en contact avec le vin.The expression “lower end face of said lower washer” is understood to mean the face of the washer intended to come into contact with the wine.

De façon optionnelle, le bouchon peut présenter, avant bouchage, un épaulement délimitant une surface d'appui destinée à venir en contact contre le buvant du col de bouteille. Cet épaulement peut être situé dans un plan radial contenant l'interface entre le corps de bouchon et ladite rondelle supérieure. Alternativement, l'épaulement peut être décalé axialement du côté de ladite rondelle inférieure par rapport à ladite interface.Optionally, the stopper may have, before corking, a shoulder delimiting a bearing surface intended to come into contact against the rim of the bottle neck. This shoulder may be located in a radial plane containing the interface between the stopper body and said upper washer. Alternatively, the shoulder can be offset axially on the side of said lower washer with respect to said interface.

On entend par « buvant du col de bouteille », la surface annulaire d'extrémité du col de bouteille.By "drinking from the bottle neck" is meant the annular end surface of the bottle neck.

Dans un mode de réalisation, le bouchon présente, avant bouchage, une forme générale tronconique s'évasant du côté de ladite rondelle inférieure.In one embodiment, the stopper has, before plugging, a generally frustoconical shape widening out on the side of said lower washer.

L'invention concerne également une bouteille contenant un vin effervescent ou un liquide gazeux munie d'un col délimitant un buvant et comprenant un bouchon tel que défini précédemment. Ladite rondelle inférieure et au moins une partie du corps de bouchon forment une portion d'obturation enfoncée dans le col de bouteille. Ladite rondelle supérieure forme au moins en partie une portion de tête du bouchon dépassant du col de bouteille.The invention also relates to a bottle containing an effervescent wine or a gaseous liquid provided with a neck delimiting a drink and comprising a stopper as defined above. Said lower washer and at least part of the stopper body form a sealing portion sunk into the bottle neck. Said upper washer forms at least in part a head portion of the stopper projecting from the bottle neck.

L'invention concerne encore un procédé de bouchage d'un col de bouteille de vin effervescent ou de liquide gazeux, à l'aide d'un bouchon tel que défini précédemment, dans lequel le bouchon est comprimé sur toute sa hauteur, puis est enfoncé dans le col de bouteille jusqu'à ce qu'une interface entre le corps de bouchon et ladite rondelle supérieure est située dans un plan radial contenant le buvant dudit col ou est décalée axialement vers l'extérieur du col par rapport audit buvant.

  • a vertical axis X directed from bottom to top, and
  • a transverse axis Y, orthogonal to the vertical axis X and horizontal.

Le bouchon 10 est de forme générale cylindrique. Le bouchon 10 comprend un corps 14 de bouchon intermédiaire et deux rondelles 16, 18 inférieures empilées axialement et situées à une extrémité 14a inférieure dudit corps de bouchon.The stopper 10 is generally cylindrical in shape. The stopper 10 comprises an intermediate stopper body 14 and two lower washers 16, 18 stacked axially and located at a lower end 14a of said stopper body.

Le bouchon 10 comprend également une rondelle 20 de tête supérieure qui est fixée à une extrémité 14b supérieure du corps de bouchon opposée axialement à l'extrémité 14a inférieure. Les extrémités 14a, 14b délimitent axialement le corps 14 de bouchon. La rondelle 20 supérieure est située axialement du côté opposé aux rondelles 16, 18 inférieures par rapport au corps 14 de bouchon.The stopper 10 also includes an upper head washer 20 which is attached to an upper end 14b of the stopper body axially opposite to the lower end 14a. The ends 14a, 14b axially delimit the body 14 of the stopper. The upper washer 20 is located axially on the side opposite the lower washers 16, 18 with respect to the plug body 14.

Comme cela sera décrit plus en détail par la suite, le corps 14 de bouchon est formé d'une pluralité de parties 22 à 26 assemblées entre elles. Les parties 22 à 26 sont empilées les unes contre les autres dans le sens transversal.As will be described in more detail later, the stopper body 14 is formed from a plurality of parts 22 to 26 assembled together. The parts 22 to 26 are stacked against each other in the transverse direction.

Chacune des rondelles 16 à 20 est réalisée en liège naturel. La rondelle 20 supérieure présente une forme cylindrique. Le diamètre de la rondelle 20 est égal à celui du corps 14 de bouchon. La rondelle 20 supérieure peut par exemple être fixée au corps 14 de bouchon par collage.Each of the washers 16 to 20 is made of natural cork. The upper washer 20 has a cylindrical shape. The diameter of the washer 20 is equal to that of the body 14 of the plug. The upper washer 20 can for example be fixed to the body 14 of the plug by gluing.

Les rondelles 16, 18 inférieures sont fixées entre elles, la rondelle 16 étant fixée à l'extrémité 14a inférieure du corps de bouchon. Chacune de ces fixations peut par exemple être réalisée par collage. La rondelle 18 est fixée à l'extrémité inférieure du corps 14 de bouchon par l'intermédiaire de la rondelle 16. Chaque rondelle 16, 18 présente une forme cylindrique. Le diamètre des rondelles 16, 18 est égal à celui du corps 14 de bouchon.The lower washers 16, 18 are fixed together, the washer 16 being fixed to the lower end 14a of the stopper body. Each of these fasteners can for example be produced by gluing. The washer 18 is fixed to the lower end of the plug body 14 by means of the washer 16. Each washer 16, 18 has a cylindrical shape. The diameter of the washers 16, 18 is equal to that of the stopper body 14.

Généralement, pour les rondelles 16 et 18, on parle respectivement de rondelles intermédiaire et miroir. La rondelle 18 comprend une face d'extrémité inférieure 28 plane destinée à venir en contact avec le vin. Dans l'exemple de réalisation illustré, le bouchon 10 comprend deux rondelles 16, 18 inférieures de hauteur identique. Alternativement, il est possible de prévoir un nombre différent de rondelles, par exemple un ou trois, et/ou des rondelles de hauteurs différentes.Generally, for washers 16 and 18, one speaks respectively of intermediate and mirror washers. The washer 18 comprises a flat lower end face 28 intended to come into contact with the wine. In the exemplary embodiment illustrated, the stopper 10 comprises two lower washers 16, 18 of identical height. Alternatively, it is possible to provide a different number of washers, for example one or three, and / or washers of different heights.

Le veinage 16a, 18a, 20a du liège naturel de chacune des rondelles 16 à 20 est orienté transversalement à l'axe longitudinal 12 du bouchon. Chaque veinage 16a, 18a, 20a s'étend ici selon une direction générale sensiblement perpendiculaire à l'axe longitudinal 12.The veining 16a, 18a, 20a of the natural cork of each of the washers 16 to 20 is oriented transversely to the longitudinal axis 12 of the stopper. Each veining 16a, 18a, 20a extends here in a general direction substantially perpendicular to the longitudinal axis 12.

Comme indiqué précédemment, le corps 14 de bouchon est formé par les parties 22 à 26 assemblées entre elles. Chaque partie 22 à 26 est réalisée en liège naturel. Le veinage 22a, 24a, 26a du liège naturel de chacune des parties 22 à 26 est orienté selon l'axe longitudinal 12 du bouchon. Chaque veinage 22a, 24a, 26a s'étend ici selon une direction générale sensiblement parallèle à l'axe longitudinal 12. Le veinage 22a, 24a, 26a du liège naturel de chacune des parties 22 à 26 s'étend sensiblement perpendiculairement aux veinages 16a à 20a du liège naturel des rondelles 16 à 20.As indicated above, the stopper body 14 is formed by the parts 22 to 26 assembled together. Each part 22 to 26 is made of natural cork. The veining 22a, 24a, 26a of the natural cork of each of the parts 22 to 26 is oriented along the longitudinal axis 12 of the stopper. Each veining 22a, 24a, 26a extends here in a general direction substantially parallel to the longitudinal axis 12. The veining 22a, 24a, 26a of the natural cork of each of the parts 22 to 26 extends substantially perpendicular to the veins 16a to 20a of natural cork from washers 16 to 20.

Les parties 22 à 26 du corps 14 de bouchon sont fixées deux à deux entre elles. Les parties 22, 24 sont fixées transversalement de part et d'autre de la partie 26. Les parties 22, 24 adjacentes sont fixées entre elles le long d'un plan d'assemblage ou de fixation 30 vertical. Les parties 24, 26 adjacentes sont fixées entre elles le long d'un plan de fixation 32 vertical. Les plans de fixation 30, 32 sont parallèles à l'axe 12 longitudinal du bouchon. Les parties 22 à 26 du corps 14 de bouchon sont fixées par collage. Le corps 14 de bouchon présente une forme cylindrique. Chaque partie 22 à 26 se présente sous la forme d'un tronçon de cylindre comme cela est illustré aux figures 1 et 2.The parts 22 to 26 of the stopper body 14 are fixed in pairs to one another. The parts 22, 24 are fixed transversely on either side of the part 26. The adjacent parts 22, 24 are fixed together along a vertical assembly or fixing plane. The adjacent parts 24, 26 are fixed together along a vertical fixing plane 32. The fixing planes 30, 32 are parallel to the longitudinal axis 12 of the stopper. The parts 22 to 26 of the stopper body 14 are fixed by gluing. The stopper body 14 has a cylindrical shape. Each part 22 to 26 is in the form of a cylinder section as illustrated in figures 1 and 2 .

Les extrémités inférieures des parties 22 à 26 sont coplanaires et forment l'extrémité 14a inférieure du corps de bouchon. Les extrémités supérieures des parties 22 à 26 sont coplanaires et forment l'extrémité 14b supérieure du corps de bouchon.The lower ends of parts 22 to 26 are coplanar and form the lower end 14a of the stopper body. The upper ends of the parts 22 to 26 are coplanar and form the upper end 14b of the stopper body.

Dans l'exemple de réalisation illustré, les dimensions transversales des parties 22 à 26 sont égales entre elles. En variante, il est possible de prévoir pour les parties 22 à 26 des dimensions transversales différentes.In the exemplary embodiment illustrated, the transverse dimensions of the parts 22 to 26 are equal to each other. As a variant, it is possible to provide for the parts 22 to 26 different transverse dimensions.

Dans l'exemple de réalisation illustré, le corps 14 de bouchon est subdivisé en trois parties 22 à 26. Alternativement, le corps 14 de bouchon pourrait être subdivisé en un nombre différent de parties 22 à 26, par exemple deux ou quatre. Dans une autre variante de réalisation, le corps 14 de bouchon pourrait être réalisé monobloc, i.e. en une seule pièce.In the illustrated embodiment, the stopper body 14 is subdivided into three parts 22 to 26. Alternatively, the stopper body 14 could be subdivided into a different number of parts 22 to 26, for example two or four. In another variant embodiment, the stopper body 14 could be made in one piece, i.e. in one piece.

L'interface ou plan de fixation entre le corps 14 de bouchon et la rondelle 20 supérieure est illustrée sur la figure 1 par la référence 34. La hauteur H1 axiale séparant cette interface 34 de la face d'extrémité inférieure 28 de la rondelle 18 est supérieure ou égale à 50 % de la hauteur H totale du bouchon 10. De préférence, la distance H1 est supérieure ou égale à 56 % de la hauteur H.The interface or plane of attachment between the plug body 14 and the upper washer 20 is illustrated in the figure. figure 1 by the reference 34. The axial height H1 separating this interface 34 from the lower end face 28 of the washer 18 is greater than or equal to 50% of the total height H of the plug 10. Preferably, the distance H1 is greater or equal to 56% of the height H.

La hauteur H2 axiale séparant l'interface 34 de la face d'extrémité supérieure 36 de la rondelle 20 est supérieure ou égale à 22.5 % de la hauteur H totale du bouchon 10, et inférieure ou égale à 44 % de cette hauteur H. La hauteur H3 du corps 14 de bouchon peut par exemple être comprise entre 33 % et 54 % de la hauteur H.The axial height H2 separating the interface 34 from the upper end face 36 of the washer 20 is greater than or equal to 22.5% of the total height H of the plug 10, and less than or equal to 44% of this height H. The height H3 of the stopper body 14 can for example be between 33% and 54% of the height H.

A titre indicatif, le diamètre du bouchon 10 est de préférence de 33 mm en dimension nominale. En variante, il est possible de prévoir un diamètre conventionnel de 31 mm en dimension nominale. A titre indicatif, la hauteur H du bouchon 10 est de préférence de 51 mm en dimension nominale. A titre indicatif, la hauteur H1 axiale peut être égale à 31 mm, et les hauteurs H2 et H3 peuvent être chacune égale à 19 mm.As an indication, the diameter of the plug 10 is preferably 33 mm in nominal size. Alternatively, it is possible to provide a conventional diameter of 31 mm in nominal size. As an indication, the height H of the plug 10 is preferably 51 mm in nominal size. As an indication, the axial height H1 may be equal to 31 mm, and the heights H2 and H3 may each be equal to 19 mm.

Sur la figure 3 est illustré un col 40 de bouteille qui est bouché à l'aide du bouchon 10 décrit précédemment. Dans cet exemple de réalisation, l'interface 34 est décalée axialement vers l'extérieur par rapport au buvant 42 du col de bouteille. Les rondelles 16, 18 inférieures et une partie du corps 14 de bouchon sont enfoncées dans le col 40 de bouteille et forment la portion d'obturation du bouchon 10. L'autre partie du corps 14 de bouchon et la rondelle 20 supérieure dépassent du col 40 et forment la portion de tête du bouchon.On the figure 3 illustrated is a bottle neck 40 which is stoppered using the stopper 10 described above. In this exemplary embodiment, the interface 34 is offset axially outwardly with respect to the mouthpiece 42 of the bottle neck. The lower washers 16, 18 and a part of the stopper body 14 are pressed into the neck 40 of the bottle and form the sealing portion of the stopper 10. The other part of the stopper body 14 and the upper washer 20 protrude from the neck 40 and form the head portion of the stopper.

Comme indiqué précédemment, dans l'exemple de réalisation illustré, l'interface 34 est décalée axialement vers l'extérieur par rapport au buvant 42 du col de bouteille. L'interface 34 est située dans une zone du bouchon 10 qui a retrouvé son diamètre initial, après la compression et l'enfoncement dans le col 40 de bouteille. Ainsi, lors du débouchage du col 40 de bouteille, le risque de rupture de la fixation entre la rondelle 20 supérieure et le corps 14 de bouchon est limité. Avantageusement, l'interface 34 peut être positionné au minimum trois mm au-dessus du buvant 42 du col de bouteille.As indicated above, in the exemplary embodiment illustrated, the interface 34 is offset axially outwardly with respect to the mouthpiece 42 of the bottle neck. The interface 34 is located in a zone of the stopper 10 which has regained its initial diameter, after compression and insertion into the neck 40 of the bottle. Thus, during the unblocking of the neck 40 of the bottle, the risk of rupture of the attachment between the upper washer 20 and the body 14 of the stopper is limited. Advantageously, the interface 34 can be positioned at least three mm above the mouthpiece 42 of the bottle neck.

Alternativement, il reste possible de prévoir un enfoncement du bouchon 10 à l'intérieur du col 40 de bouteille de sorte que l'interface 34 est située dans le plan radial contenant le buvant 42 du col. Dans ce cas, les rondelles 16, 18 inférieures et la totalité du corps 14 de bouchon sont enfoncées dans le col 40 de bouteille, seule la rondelle 20 supérieure dépasse du col et forme la portion de tête du bouchon. Cependant, par rapport au positionnement de l'interface 34 tel qu'indiqué précédemment, lors du débouchage du col 40 de bouteille, le risque de désolidarisation de la rondelle 20 du corps 14 de bouchon est ici augmenté. Dans une autre alternative, l'interface 34 peut être décalée axialement à l'intérieur du col 40 de bouteille par rapport au buvant 42 du col.Alternatively, it remains possible to provide a depression of the stopper 10 inside the neck 40 of the bottle so that the interface 34 is located in the radial plane containing the mouthpiece 42 of the neck. In this case, the lower washers 16, 18 and the whole of the stopper body 14 are pressed into the bottle neck 40, only the upper washer 20 protrudes from the neck and forms the head portion of the stopper. However, compared to the positioning of the interface 34 as indicated above, when unblocking the neck 40 of the bottle, the risk of disconnection of the washer 20 from the body 14 of the stopper is here increased. In another alternative, the interface 34 can be offset axially inside the neck 40 of the bottle with respect to the mouthpiece 42 of the neck.

A l'étape de bouchage du col 40 de bouteille telle qu'illustrée à la figure 3, la plaque de muselet et le muselet empêchant l'expulsion du bouchon 10 n'ont pas encore été fixés sur celui-ci.At the stage of corking the neck 40 of the bottle as illustrated in figure 3 , the muselet plate and the muselet preventing the expulsion of the stopper 10 have not yet been fixed thereon.

Dans le premier exemple de réalisation illustré, le bouchon 10 présente, avant bouchage, une surface extérieure cylindrique sur toute sa hauteur.In the first exemplary embodiment illustrated, the stopper 10 has, before plugging, a cylindrical outer surface over its entire height.

Dans l'exemple de réalisation illustré à la figure 4, sur laquelle les éléments identiques portent les mêmes références, le bouchon 10 présente avant bouchage un épaulement 44 annulaire qui est orienté axialement vers le bas, i.e. en direction des rondelles 16, 18 inférieures. L'épaulement 44 s'étend radialement. A titre indicatif, pour un bouchon présentant un diamètre de 33 mm, la dimension radiale de l'épaulement peut être comprise entre 0.5 mm et 4 mm.In the exemplary embodiment illustrated in figure 4 , on which the identical elements bear the same references, the stopper 10 has, before plugging, an annular shoulder 44 which is oriented axially downwards, ie in the direction of the lower washers 16, 18. The shoulder 44 extends radially. As an indication, for a plug having a diameter of 33 mm, the radial dimension of the shoulder may be between 0.5 mm and 4 mm.

L'épaulement 44 est formé sur le corps 14 de bouchon. L'épaulement 44 délimite une surface d'appui destiné à venir en contact contre le buvant du col de bouteille lors de l'enfoncement du bouchon dans ce col. Ainsi, on garantit la précision et la régularité de la profondeur de bouchage. Après bouchage, le positionnement souhaité de l'interface 34 du bouchon 10 relativement au buvant du col de bouteille est garanti.The shoulder 44 is formed on the body 14 of the plug. The shoulder 44 defines a bearing surface intended to come into contact against the drink of the bottle neck when inserting the stopper in this neck. This guarantees the precision and regularity of the plugging depth. After corking, the desired positioning of the interface 34 of the stopper 10 relative to the rim of the bottle neck is guaranteed.

L'épaulement 44 est ici décalé axialement vers le bas, i.e. du côté des rondelles 16, 18 inférieures, par rapport à l'interface 34. En variante, il est possible de prévoir une disposition relative de l'interface 34 et de l'épaulement 44 de sorte à ce qu'ils soient situés dans le même plan radial.The shoulder 44 is here offset axially downwards, ie on the side of the lower washers 16, 18, relative to the interface 34. As a variant, it is possible to provide a relative arrangement of the interface 34 and of the shoulder 44 so that they are located in the same radial plane.

Dans cet exemple de réalisation, la surface extérieure du bouchon 10, qui est située axialement entre l'épaulement 44 et la face d'extrémité inférieure 28 de la rondelle 18, présente une forme tronconique s'évasant vers le bas. La surface extérieure du reste du bouchon 10 est cylindrique.In this exemplary embodiment, the outer surface of the plug 10, which is located axially between the shoulder 44 and the lower end face 28 of the washer 18, has a frustoconical shape widening downwards. The outer surface of the remainder of cap 10 is cylindrical.

Dans les exemples de réalisation illustrés, au moins une partie du bouchon 10 présente, avant bouchage, une surface extérieure cylindrique. Alternativement, le bouchon 10 peut présenter sur toute sa hauteur une surface extérieure tronconique. A titre indicatif, le diamètre du bouchon 10 au niveau de son extrémité supérieure est de préférence de 31 mm en dimension nominale. Le diamètre du bouchon 10 au niveau de son extrémité inférieure est de préférence de 33 mm en dimension nominale.In the exemplary embodiments illustrated, at least part of the stopper 10 has, before corking, a cylindrical outer surface. Alternatively, the stopper 10 can have a frustoconical outer surface over its entire height. As an indication, the diameter of the plug 10 at its upper end is preferably 31 mm in nominal size. The diameter of the plug 10 at its lower end is preferably 33 mm in nominal size.

L'invention a été illustrée sur la base d'un bouchon comprenant une unique rondelle de tête supérieure en liège naturel. En variante, il est possible, sans sortir du cadre de l'invention, de prévoir un bouchon qui comprend plusieurs rondelles supérieures empilées.The invention has been illustrated on the basis of a stopper comprising a single upper head washer made of natural cork. As a variant, it is possible, without departing from the scope of the invention, to provide a plug which comprises several stacked upper washers.
