Description

L'invention a pour objet une bouteille destinée à contenir une boisson pétillante ou gazeuse, notamment du champagne et présentant un goulot apte à recevoir en son intérieur un bouchon déformabie.The subject of the invention is a bottle intended to contain a sparkling or carbonated drink, in particular champagne and having a neck capable of receiving a deformable stopper inside.

La fermeture d'une bouteille contenant une boisson pétillante ou gazeuse, par exemple une bouteille de champagne, de vin mousseux ou de cidre de Normandie est réalisée à l'aide d'un bouchon déformable en liège ou en matière plastique, le bouchon étant généralement assuré sur la bouteille à l'aide d'une couronne de fil de fer, appelée panier, le tout étant enfermé dans une capsule métallique.The closure of a bottle containing a sparkling or carbonated drink, for example a bottle of champagne, sparkling wine or Normandy cider is carried out using a deformable cork or plastic stopper, the stopper generally being secured on the bottle using a crown of wire, called a basket, all enclosed in a metal capsule.

Lorsqu'on veut déboucher la bouteille, on enlève le panier après avoir déchiré la capsule métallique entourant le goulot. Dès que le panier est enlevé, s'il s'agit d'une bouteille de champagne ou de vin mousseux, ou le bouchon sort seul et l'opérateur est surpris, ou l'opérateur a de grosses difficultés à le décoller de la surface intérieure du goulot. Il doit alors le pousser avec l'extrémité des pouces tout en tenant le goulot dans ses mains. Dès que le bouchon est décollé, ou il sort seul, ou l'opérateur doit effectuer plusieurs rotations du bouchon par rapport au goulot pour arriver à le faire sortir.When we want to unclog the bottle, we remove the basket after tearing the metal capsule surrounding the neck. As soon as the basket is removed, if it is a bottle of champagne or sparkling wine, or the cork comes out alone and the operator is surprised, or the operator has great difficulty peeling it off the surface inside of the neck. He must then push it with the tips of the thumbs while holding the neck in his hands. As soon as the cap is unstuck, or it comes out alone, or the operator must make several rotations of the cap relative to the neck to get it out.

Le but de la présente invention est de supprimer ces inconvénients et de proposer une bouteille présentant un goulot permettant de décoller le bouchon d'un simple mouvement du poignet et de réaliser ou contrôler la sortie dudit bouchon en poursuivant ce même mouvement.The object of the present invention is to eliminate these drawbacks and to propose a bottle having a neck allowing the cap to be detached with a simple movement of the wrist and to produce or control the outlet of said cap while continuing this same movement.

La bouteille selon l'invention est caractérisée en ce que la partie intérieure du goulot présente au moins deux rainures ou nervures descendant le long du goulot selon un pas rapide sur une longueur correspondant sensiblement à la longueur du bouchon destinée à être introduite dans le gouiot et parcourant au plus un demi-pas.The bottle according to the invention is characterized in that the inner part of the neck has at least two grooves or ribs descending along the neck in a rapid step over a length corresponding substantially to the length of the stopper intended to be introduced into the necker and walking at most half a step.

Selon un mode d'exécution, trois nervures peuvent descendre à l'intérieur du goulot, les nervures étant régulièrement réparties sur le pourtour intérieur du goulot. Les nervures peuvent d'autre part prendre naissance à une certaine distance du haut du goulot, qui présente une surface intérieure cylindrique lisse jusqu'à la naissance des nervures.According to one embodiment, three ribs can descend inside the neck, the ribs being regularly distributed over the inner periphery of the neck. The ribs can also originate at a certain distance from the top of the neck, which has a smooth cylindrical interior surface until the ribs are born.

Selon un autre mode d'exécution, des nervures peuvent descendre à l'intérieur du goulot en s'élargissant dans le sens de la circonférence du goulot au fur et à mesure de leur descente dans le goulot.According to another embodiment, ribs can descend inside the neck by widening in the direction of the circumference of the neck as they descend into the neck.

Selon un troisième mode d'exécution, au moins deux rainures de plusieurs millimètres de largeur mesurées sur la circonférence descendent dans le goulot et se présentent sous forme de surfaces gauches dont la section par un plan perpendiculaire à l'axe du goulot comporte des segments de droite reliant les rainures, la courbe fermée ainsi constituée dans le plan descendant à l'intérieur du goulot en effectuant une rotation.According to a third embodiment, at least two grooves of several millimeters in width measured on the circumference descend into the neck and are in the form of left surfaces whose section by a plane perpendicular to the axis of the neck comprises segments of straight connecting the grooves, the closed curve thus formed in the downward plane inside the neck by performing a rotation.

Le goulot de bouteille représenté dans les fig. 1 à 10 est un goulot destiné à être fermé par un bouchon présentant une partie supérieure dépassant le goulot et susceptible d'être saisi dans la main de l'utilisateur lorsque celui-ci veut déboucher la bouteille. Le type de goulot qui sera décrit ci-dessous est donc prévu pour les bouteilles comprenant des liquides, notamment des breuvages tels que champagnes, vins champagnisés ou mousseux, vins, cidres, etc.The bottle neck shown in Figs. 1 to 10 is a neck intended to be closed by a stopper having an upper part projecting from the neck and capable of being grasped in the hand of the user when the latter wishes to unclog the bottle. The type of neck which will be described below is therefore intended for bottles comprising liquids, in particular beverages such as champagnes, champagnized or sparkling wines, wines, ciders, etc.

Dans le mode d'exécution des fig. 1 et 2, le goulot 1 est fermé à l'aide d'un bouchon 2 de type utilisé pour les bouteilles de champagne ou de cidre de Normandie et comprenant une tête 3 et une partie inférieure 4 enfilée dans le goulot 1. Le bouchon 2, qui est habituellement en liège, sera assuré sur le goulot 1 de manière connue avec un panier de fil de fer non représenté formant deux couronnes placées respectivement sur la tête 3 du bouchon 2 et contre les rebords annulaires 5 autour du goulot 1, les deux couronnes étant maintenues ensemble par quatre fils de fer de liaison régulièrement réparties autour de la périphérie du goulot 1. Comme représenté dans les fig. 1 et 2, l'intérieur du goulot 1 présente deux rainures hélicoïdales 6 et 7 opposées à 180° sur la circonférence du goulot 1 et partant du haut du goulot 1 et descendant dans son intérieur dans le sens des aiguilles d'une montre (fig. 2). Les rainures 6 et 7 présentent une configuration semblable à une partie de sinusoïde très aplatie, les bords des rainures se raccordant tangentiellement et sans discontinuité au pourtour intérieur du goulot 1 selon une courbure à grand rayon. Les rainures 6 et 7 descendent à l'intérieur du goulot 1 en effectuant environ 1/4 de tour dans le sens des aiguilles d'une montre et s'étendent sur une longueur plus petite que la longueur sur laquelle descend l'extrémité de la partie inférieure 4 du bouchon 2. D'autre part, l'épaisseur des rainures 6 et 7 mesurée perpendiculairement à la paroi du goulot, va en s'amincissant au fur et à mesure que les rainures descendent le long du goulot 1 pour disparaître et se confondre avec la partie intérieure du goulot, comme représenté en 8 dans la fig. 2.In the embodiment of fig. 1 and 2, the neck 1 is closed using a cap 2 of the type used for bottles of champagne or Normandy cider and comprising a head 3 and a lower part 4 threaded into the neck 1. The cap 2 , which is usually made of cork, will be provided on the neck 1 in a known manner with a wire basket, not shown, forming two crowns placed respectively on the head 3 of the plug 2 and against the annular edges 5 around the neck 1, both crowns being held together by four connecting wires regularly distributed around the periphery of the neck 1. As shown in FIGS. 1 and 2, the inside of the neck 1 has two helical grooves 6 and 7 opposite 180 ° on the circumference of the neck 1 and starting from the top of the neck 1 and descending in its interior in a clockwise direction (fig 2). The grooves 6 and 7 have a configuration similar to a very flat sinusoid part, the edges of the grooves connecting tangentially ment and without discontinuity around the inside of the neck 1 according to a curvature with a large radius. The grooves 6 and 7 descend inside the neck 1 by carrying out approximately 1/4 of a turn clockwise and extend over a shorter length than the length over which the end of the lower part 4 of the plug 2. On the other hand, the thickness of the grooves 6 and 7 measured perpendicular to the wall of the neck, becomes thinner as the grooves descend along the neck 1 to disappear and merge with the inside of the neck, as shown in 8 in fig. 2.

Le fait que les rainures 6 et 7 présentent un profil sous forme d'une partie de sinusoïde très aplatie avec des extrémités rejoignant tangentiellement la périphérie intérieure du goulot 1 permet au bouchon d'épouser totalement la configuration des rainures 6 et 7 dès qu'il est introduit dans le goulot 1. La surface latérale de la partie inférieure 4 du bouchon est donc partout en contact avec la surface intérieure du goulot 1, y compris sur toute la largeur des rainures 6 et 7 qui sont volontairement réalisées de manière à être larges, peu profondes et sans arêtes ou dicontinuités sur lesquelles ou à côté desquelles le bouchon pourrait ne pas s'appliquer et laisser des passages ou sorties vers l'extrémité supérieure du goulot.The fact that the grooves 6 and 7 have a profile in the form of a very flat sinusoid part with ends tangentially joining the inner periphery of the neck 1 allows the plug to fully conform to the configuration of the grooves 6 and 7 as soon as it is introduced into the neck 1. The lateral surface of the lower part 4 of the plug is therefore everywhere in contact with the internal surface of the neck 1, including over the entire width of the grooves 6 and 7 which are deliberately made so as to be wide , shallow and without edges or dicontinuities on or near which the plug may not apply and leave passages or outlets towards the upper end of the neck.

Les rainures 6 et 7 du mode d'exécution des fig. 1 et 2 auront approximativement une largeur moyenne allant jusqu'à deux millimètres. Les bouchons des bouteilles de vins champagnisés étant agencés pour entrer dans les goulots sur une distance de 3 à 4 centimètres, les rainures 6 et 7 auront une longueur de 3 centimètres au plus. Selon une variante, on peut prévoir comme représenté en 9 selon la ligne pointillée dans la fig. 1, un goulot dont la partie inférieure va en s'élargissant. Le bouchon 2 sera ainsi mieux tenu dans le goulot 1, étant donné qu'il devra subir une déformation pour pouvoir être sorti.The grooves 6 and 7 of the embodiment of FIGS. 1 and 2 will have an average width of up to two millimeters. The corks of champagne bottles being arranged to enter the necks over a distance of 3 to 4 centimeters, the grooves 6 and 7 will have a length of 3 centimeters at most. Alternatively, one can provide as shown in 9 along the dotted line in FIG. 1, a neck, the lower part of which widens. The plug 2 will thus be better held in the neck 1, since it will have to undergo a deformation to be able to be removed.

Le bouchon 2 est mis en place dans le goulot représenté dans les fig. 1 et 2 de manière connue. La partie supérieure du bouchon 2 est ensuite pressée de manière à former la tête 3 lors de la mise en place de la couronne de fil de fer non représentée destinée à assurer le bouchon sur la bouteille. Le goulot est ensuite enfermé dans une capsule non représentée. Pour ouvrir la bouteille, on enlève préalablement la capsule et la couronne de fil de fer non représentées et l'on saisit la tête 3 du bouchon dans la main. Il suffit alors de faire tourner d'un quart de tour environ le bouchon dans le sens contraire des aiguilles d'une montre pour pouvoir le sortir. Il est à remarquer que le bouchon est sous pression et que la rotation qui lui est appliquée sert à le décoller des parois intérieures du goulot 1 et à contrôler sa sortie qui est donc partiellement due à la poussée exercée sur la surface libre de la partie inférieure 4. La caractéristique intéressante des rainures de guidage 6 et 7 réside dans le fait qu'elles s'étendent sur environ un quart de tour de la circonférence du goulot. La bouteille peut donc être débouchée et la sortie du bouchon 2 contrôlée par un simple coup de poignet de l'utilisateur. Il suffit donc d'empoigner la tête 3 du bouchon 2 et de le sortir en une fois par un seul et unique mouvement du poignet.The plug 2 is placed in the neck shown in FIGS. 1 and 2 in a known manner. The upper part of the stopper 2 is then pressed so as to form the head 3 when the crown of wire, not shown, intended to secure the stopper on the bottle is put in place. The neck is then enclosed in a capsule, not shown. To open the bottle, the capsule and the crown of wire (not shown) are removed beforehand and the head 3 of the stopper is grasped in the hand. It then suffices to turn the cap about a quarter of a turn anti-clockwise to be able to remove it. It should be noted that the plug is under pressure and that the rotation which is applied to it serves to detach it from the interior walls of the neck 1 and to control its exit which is therefore partially due to the thrust exerted on the free surface of the lower part 4. The interesting characteristic of the guide grooves 6 and 7 lies in the fact that they extend over approximately a quarter of a turn of the circumference of the neck. The bottle can therefore be uncorked and the outlet from the stopper 2 controlled by a simple wrist from the user. It therefore suffices to grasp the head 3 of the plug 2 and take it out at once by a single movement of the wrist.

Les rainures 6 et 7 auront une largeur (mesurée sur la circonférence du goulot allant de 1 à quelques millimètres et une profondeur (mesurée sur le rayon) allant jusqu'au plus deux millimètres.The grooves 6 and 7 will have a width (measured on the circumference of the neck ranging from 1 to a few millimeters and a depth (measured on the radius) of up to two millimeters.

Dans le mode d'exécution des fig. 3 et 4, le goulot 1 muni de son rebord extérieur 5 présente sur sa surface intérieure 14 trois petites nervures 11, 12 et 13 descendant dans le goulot 1 en parcourant environ 1/3 de la circonférence dudit goulot. Les rainures 11 à 13 présentent une configuration circulaire de moins de un millimètre d'épaisseur (mesurée sur la circonférence) et de profondeur (mesurée sur le rayon du goulot 1). Dans le mode d'exécution des fig. 3 et 4, les nervures 11 à 13 présentent un profil arrondi, mais il est évident qu'elles peuvent dans des variantes non représentées être de section carrée ou rectangulaire, voire même triangulaire. Vu leur petite dimension, elles ne vont pas en s'amincissant au fur et à mesure de leur descente à l'intérieur du goulot 1 et présentent par conséquent le même profil sur toute leur longueur. Seule leur extrémité 14 est arrondie et s'amincit pour mourir sur la surface intérieure du goulot, de manière à ce que cette extrémité ne retienne pas le bouchon non représenté lorsqu'il est enlevé dans le cas où l'extrémité inférieure de ce dernier pénètre dans le goulot 1 au-delà des rainures 11 à 13. Des essais effectués par le déposant avec un prototype conforme au mode d'exécution des fig. 3 et 4 et présentant des rainures de forme carrée de 1/2 millimètre de côté environ ont montré qu'un bouchon de liège reste parfaitement étanche lorsqu'il est enfilé dans le goulot 1.In the embodiment of fig. 3 and 4, the neck 1 provided with its outer rim 5 has on its inner surface 14 three small ribs 11, 12 and 13 descending into the neck 1 by traversing approximately 1/3 of the circumference of said neck. The grooves 11 to 13 have a circular configuration of less than a millimeter in thickness (measured on the circumference) and in depth (measured on the radius of the neck 1). In the embodiment of fig. 3 and 4, the ribs 11 to 13 have a rounded profile, but it is obvious that in variants not shown, they may be of square or rectangular section, or even triangular. Given their small size, they do not become thinner as they descend inside the neck 1 and therefore have the same profile over their entire length. Only their end 14 is rounded and thins to die on the interior surface of the neck, so that this end does not retain the stopper, not shown when it is removed in the case where the lower end of the latter penetrates. in the neck 1 beyond the grooves 11 to 13. Tests carried out by the applicant with a prototype conforming to the embodiment of FIGS. 3 and 4 and having square grooves of approximately 1/2 millimeter on a side have shown that a cork stopper remains perfectly tight when it is threaded into the neck 1.

Dans le mode d'exécution des fig. 5 et 6, le goulot 1 est un goulot d'une bouteille destinée à contenir du champagne. Selon la méthode champenoise, le vin est, lors d'une des phases de vinification, mis en bouteille et bouché avec une petite capsule non représentée en matière plastique de 10 millimètres de longueur introduite dans le goulot. Dès que cette capsule appelée « bidule a a été mise en place, le vin repose quelques temps et les impuretés qu'il peut contenir montent dans le liquide pour s'assembler sous cette capsule. Le goulot de la bouteille est alors fortement refroidi et il se forme sous la capsule appelée « bidule un glaçon contenant les impuretés qui sera éjecté par la suite. Le détail de la méthode champenoise ne sera pas donné ci-après, car cette méhode est complexe et sort du cadre de la présente description. Il suffit de savoir que les bouteilles utilisées en Champagne doivent obligatoirement permettre la fermeture momentanée avec la capsule appelée « bidule », et le mode d'exécution des fig. 5 et 6 est une bouteille de ce type, qui sera fermée à l'aide du bouchon en liège 2 comprenant lorsqu'il est en place sur le goulot 1 une tête 3 de forme arrondie et une partie inférieure 4 enfilée à l'intérieur du goulot 1 sur une longueur d'au moins 20 millimètres. Le bouchon 2 sera assuré sur le goulot 1 de manière connue avec un fil de fer non représenté formant un panier fixé respectivement sur la tête 3 du bouchon 2 et sous le rebord annulaire 5 du goulot 1. L'intérieur du goulot 1 présente six nervures hélicoïdales 16 régulièrement réparties sur sa périphérie et descendant le long des parois intérieures selon le sens des aiguilles d'une montre. Comme représenté dans la fig. 6, les nervures 16 présentent une configuration arrondie, sans arête coupante. Le haut 17, comme le bas 18 de chaque nervure 16 présente également une forme arrondie pour éviter toute détérioration du bouchon 2, lorsque celui-ci est mis en place ou enlevé. Comme représenté dans la fig. 5, les parois intérieures du goulot sont parfaitement cylindriques sur une distance de environ 20 millimètres, à partir du haut du goulot 1, le diamètre de l'intérieur du goulot 1 commençant à s'élargir après cette distance de 20 mm. Il est visible sur la fig. 5 que la paroi intérieure du goulot 1 est parfaitement lisse sur les dix premiers millimètres, les nervures 16 s'étendant sur les dix millimètres suivant pour s'arrêter par conséquent à 20 millimètres du haut du goulot. Le fait que les surfaces intérieures du goulot 1 sont lisses sur les dix premiers millimètres permet la mise en place de la capsule en plastique appelée « bidule et le mode d'exécution des fig. 5 et 6 peut être utilisé pour contenir des vins de champagne et permettre toutes les opérations inhérentes à ce procédé de champagnisation.In the embodiment of fig. 5 and 6, the neck 1 is a neck of a bottle intended to contain champagne. According to the Champagne method, the wine is, during one of the vinification phases, bottled and capped with a small capsule, not shown, made of plastic, 10 millimeters in length, introduced into the neck. As soon as this capsule called “bidule has been put in place, the wine rests for some time and the impurities that it can contain rise in the liquid to assemble under this capsule. The neck of the bottle is then strongly cooled and it is formed under the capsule called “bidule an ice cube containing the impurities which will be ejected thereafter. The details of the Champagne method will not be given below, since this method is complex and is beyond the scope of this description. It is enough to know that the bottles used in Champagne must obligatorily allow the temporary closing with the capsule called "bidule", and the mode of execution of fig. 5 and 6 is a bottle of this type, which will be closed using the cork stopper 2 comprising when in place on the neck 1 a head 3 of rounded shape and a lower part 4 threaded inside the neck 1 over a length of at least 20 millimeters. The plug 2 will be provided on the neck 1 in a known manner with an iron wire, not shown, forming a basket fixed respectively on the head 3 of the plug 2 and under the annular rim 5 of the neck 1. The interior of the neck 1 has six ribs helical 16 regularly distributed over its periphery and descending along the interior walls in a clockwise direction. As shown in fig. 6, the ribs 16 have a rounded configuration, without a cutting edge. The top 17, like the bottom 18 of each rib 16 also has a rounded shape to avoid any deterioration of the plug 2, when the latter is put in place or removed. As shown in fig. 5, the interior walls of the neck are perfectly cylindrical over a distance of about 20 millimeters, from the top of the neck 1, the inside diameter of the neck 1 starting to widen after this distance of 20 mm. It is visible in fig. 5 that the inside wall of the neck 1 is perfectly smooth over the first ten millimeters, the ribs 16 extending over the next ten millimeters, therefore stopping 20 millimeters from the top of the neck. The fact that the interior surfaces of the neck 1 are smooth over the first ten millimeters allows the establishment of the plastic capsule called “contraption and the embodiment of FIGS. 5 and 6 can be used to contain champagne wines and allow all the operations inherent in this champagnisation process.

Comme visible sur les fig. 5 et 6, les nervures 16 sont de petite dimension et présentent une largeur de moins d'un millimètre et une longueur de 10 mm. Elles forment un angle de 30° environ avec la verticale, de sorte que le bouchon peut être sorti après une rotation de un demi-tour au maximum.As seen in fig. 5 and 6, the ribs 16 are small and have a width of less than a millimeter and a length of 10 mm. They form an angle of approximately 30 ° with the vertical, so that the plug can be removed after a maximum rotation of half a turn.

Le bouchon 2 est mis en place.dans le goulot 1 représenté dans les fig. 5 et 6 de manière connue, c'est-à-dire de manière à être enfoncé d'au moins 20 mm dans le goulot de la bouteille et de laisser au-dessus de l'extrémité supérieure du goulot une partie qui sera ensuite pressée de manière à former la tête 3. Cette tête 3 servira à la mise en place du panier de fil de fer non représenté destiné à assurer fermement le bouchon sur la bouteille. Le goulot est ensuite enfermé dans une capsule métallique non représentée. Pour ouvrir la bouteille, on enlève préalablement cette capsule et le panier de fil de fer non représenté. On saisit ensuite la tête 3 du bouchon 2 dans la main et il suffit alors de faire tourner le bouchon de 1/4 à 1/2 tour dans le sens contraire des aiguilles d'une montre pour pouvoir le sortir. Le liquide à l'intérieur de la bouteille étant sous pression, la rotation que l'utilisateur imprime avec sa main au bouchon sert d'abord à décoller le bouchon des parois intérieures du goulot et à contrôler sa sortie qui est par conséquent partiellement due à la poussée exercée sur la surface libre de la partie inférieure 4 dudit bouchon. La caractéristique intéressante des rainures 16 du mode d'exécution des fig. 5 et 6 réside dans le fait que les rainures de guidage 16 s'étendent sur une partie de la circonférence intérieure du goulot 1 en formant un angle approximatif de 30° avec la verticale. Le bouchon peut donc être sorti par une rotation d'un demi tour au plus exécutée par la main de l'utilisateur. Comme les rainures commencent après 10 mm environ à partir du sommet du goulot, la capsule plastique normalement utilisée dans la méthode champenoise pour la fabrication des champagnes peut être introduite dans le goulot et retirée. Il est finalement à remarquer que l'extrémité 18 des nervures 6 se situe à l'endroit où la paroi intérieure du goulot 1 est encore cylindrique. Les nervures 6 étant de très petites dimensions, il n'y a pas lieu de craindre qu'elles retiennent le glaçon contenant les impuretés lorsque celui-ci sera éjecté.The plug 2 is placed in the neck 1 shown in FIGS. 5 and 6 in a known manner, that is to say so as to be pressed at least 20 mm into the neck of the bottle and to leave above the upper end of the neck a portion which will then be pressed so as to form the head 3. This head 3 will be used for the establishment of the wire basket, not shown, intended to firmly secure the stopper on the bottle. The neck is then enclosed in a metal capsule, not shown. To open the bottle, this capsule and the wire basket, not shown, are removed beforehand. The head 3 of the plug 2 is then grasped in the hand and it then suffices to rotate the plug 1/4 to 1/2 turn counterclockwise to be able to remove it. The liquid inside the bottle being under pressure, the rotation that the user prints with his hand to the stopper is first used to unstick the stopper from the inside walls of the neck and to control its exit which is consequently partly due to the thrust exerted on the free surface of the lower part 4 of said plug. The interesting feature of the grooves 16 of the embodiment of FIGS. 5 and 6 resides in the fact that the guide grooves 16 extend over part of the inner circumference of the neck 1 at an approximate angle of 30 ° with the vertical. The plug can therefore be removed by a rotation of at most half a turn executed by the hand of the user. As the grooves start after approximately 10 mm from the top of the neck, the plastic capsule normally used in the Champagne method for the production of champagnes can be introduced into the neck and removed. Finally, it should be noted that the end 18 of the ribs 6 is located at the point where the interior wall of the neck 1 is still cylindrical. The ribs 6 being very small, there is no reason to fear that they will retain the ice cube containing the impurities when the latter is ejected.

Bien que le mode d'exécution des fig. 5 et 6 qui vient d'être décrit concerne un goulot de bouteille de champagne présentant six nervures, il est évident que ce nombre de nervures peut être augmenté ou diminué. Il est encore plus évident pour l'homme du métier que plus le nombre de nervures est grand, plus leur largeur dans le sens de la circonférence et leur hauteur dans le sens du diamètre peuvent être de dimensions réduites. En effet, lorsque la main de l'utilisateur imprime une rotation au bouchon 2, les nervures 6 présentent des flancs contre lesquels s'appuye le bouchon pour tourner. Par conséquent, un grand nombre de nervures permet de réduire les surfaces de ces flancs et par conséquent les grandeurs (largeur dans le sens de la circonférence et hauteur dans le sens du diamètre) de ces rainures.Although the mode of execution of fig. 5 and 6 which has just been described relates to a neck of a champagne bottle having six ribs, it is obvious that this number of ribs can be increased or decreased. It is even more obvious to a person skilled in the art that the greater the number of ribs, the smaller their width in the direction of the circumference and their height in the direction of the diameter. In fact, when the hand of the user rotates the plug 2, the ribs 6 have flanks against which the plug bears to rotate. Consequently, a large number of ribs makes it possible to reduce the surfaces of these flanks and consequently the sizes (width in the direction of the circumference and height in the direction of the diameter) of these grooves.

Dans le mode d'exécution des fig. 7 et 8, le goulot 1 est muni comme le mode d'exécution précédent sur son pourtour extérieur d'un rebord 5 qui permettra de retenir le bas du panier de fil de fer destiné à assurer un bouchon non représenté. Le goulot 1 présente une paroi intérieure sensiblement cylindrique sur au moins 20 mm de profondeur à partir du haut du goulot. Sur cette partie cylindrique sont prévues trois nervures 20 régulièrement réparties sur le pourtour de la circonférence intérieure du goulot 1. Ces nervures 20 descendent selon une spirale à l'intérieur du goulot 1 dans le sens des aiguilles d'une montre et forment un angle d'environ 30° avec la verticale. Chaque rainure parcourt environ 1/3 de la circonférence du goulot et elles vont en s'amincissant dans leur largeur (dimension mesurée sur la circonférence du goulot) au fur et à mesure qu'elles se rapprochent du bord supérieur du goulot. Dans le mode d'exécution des fig. 7 et 8, leur hauteur (dimension mesurée sur le diamètre du goulot) reste sensiblement constante. Selon une première variante, les rainures 20 peuvent présenter une hauteur (dimension mesurée selon le diamètre du goulot 1) qui va en s'amincissant au fur et à mesure que l'on descend à l'intérieur de la bouteille comme représenté par la ligne pointillée 21 de la fig. 8. Selon une deuxième variante, la rainure peut ne pas s'étendre sur les 20 mm de la partie cylindrique de la paroi intérieure du goulot 1, mais s'arrêter avant comme représenté en 22 sur la fig. 7.In the embodiment of fig. 7 and 8, the neck 1 is provided like the previous embodiment on its outer periphery with a rim 5 which will retain the bottom of the wire basket intended to ensure a stopper not shown. The neck 1 has a substantially cylindrical inner wall at least 20 mm deep from the top of the neck. On this cylindrical part are provided three ribs 20 regularly distributed around the periphery of the inner circumference of the neck 1. These ribs 20 descend in a spiral inside the neck 1 in a clockwise direction and form an angle d '' about 30 ° with the vertical. Each groove runs around 1/3 of the circumference of the neck and they become thinner in width (dimension measured on the circumference of the neck) as they approach the upper edge of the neck. In the embodiment of fig. 7 and 8, their height (dimension measured on the diameter of the neck) remains substantially constant. According to a first variant, the grooves 20 may have a height (dimension measured according to the diameter of the neck 1) which becomes thinner as one descends inside. of the bottle as shown by the dotted line 21 in fig. 8. According to a second variant, the groove may not extend over the 20 mm of the cylindrical part of the interior wall of the neck 1, but stop before as shown at 22 in FIG. 7.

Comme les rainures du mode d'exécution précédent, les rainures 20 du mode d'exécution des fig. 7 et 8 sont de forme arrondie et ne présentent pas d'arête coupante dans le but d'éviter d'endommager les bouchons. L'extrémité supérieure 23 et inférieure 24 des rainures présentent également une forme arrondie. Les rainures 20 présentent à leur extrémité inférieure 24 une largeur mesurée dans le sens de la circonférence de plus de 1 mm, et une hauteur mesurée dans le sens du diamètre de moins de 1 mm. A leur partie supérieure, les rainures 10 présentent une hauteur de moins de 1 mm et une largeur également inférieure à 1 mm. Il va de soi que les dimensions données ci-dessus sont un ordre de grandeur et qu'elles peuvent varier en fonction de nombreux facteurs, par exemple en fonction de la qualité des bouchons ou de la matière qui constitue ces bouchons.Like the grooves of the previous embodiment, the grooves 20 of the embodiment of FIGS. 7 and 8 are rounded in shape and do not have a cutting edge in order to avoid damaging the plugs. The upper 23 and lower 24 ends of the grooves also have a rounded shape. The grooves 20 have at their lower end 24 a width measured in the direction of the circumference of more than 1 mm, and a height measured in the direction of the diameter of less than 1 mm. At their upper part, the grooves 10 have a height of less than 1 mm and a width also less than 1 mm. It goes without saying that the dimensions given above are an order of magnitude and that they can vary as a function of many factors, for example as a function of the quality of the plugs or of the material which constitutes these plugs.

Dans le mode d'exécution des fig. 9 et 10, le goulot 1 présente comme dans les modes d'exécution précédents un rebord 5 qui permettra de fixer un panier de fil de fer non représenté à sa partie inférieure et dont la partie supérieure viendra s'appliquer contre une tête d'un bouchon également non représentée. Comme représenté dans la fig. 10, le goulot se présente à sa partie supérieure sous la forme d'un triangle équilatéral dont les sommets sont arrondis, tel que représenté en 25. Par rapport à un orifice circulaire de configuration normale représenté en pointillé selon la ligne 26 de la fig. 10, le profil du goulot présente donc une succession de creux 27 et de parties aplaties 28, respectivement 29, 30 et 31, 32. Cette configuration sous forme d'un triangle équilatéral aux sommets arrondis entre à l'intérieur du goulot selon une spirale dans le sens des aiguilles d'une montre et s'étend sur environ 20 mm. On comprend aisément que les creux 27, 29 et 31 forment chacun une rainure qui descend à l'intérieur du goulot avec un mouvement de rotation dans le sens des aiguilles d'une montre. De même, les parties 28, 30 et 32 forment des surfaces de guidage présentant la même inclinaison que les rainures 27, 29 et 31. La configuration du pourtour 25 de la surface intérieure du goulot 1 est réalisée de manière à présenter la même surface que la configuration circulaire normale représentée par la ligne pointillée 26 (fig. 10). De cette manière, on pourra placer à l'intérieur du goulot 1 du mode d'exécution des fig. 9 et 10, un bouchon semblable au bouchon normalement utilisé pour les goulots normaux à configuration circulaire. Lorsque le bouchon sera mis en place, il remplira totalement l'intérieur du goulot en occupant la place laissée par les rainures 27, 29 et 31 et en étant repoussé par les parties 28, 30 et 32. Lorsque l'on fera tourner le bouchon dans le sens contraire aux aiguilles d'une montre, les rainures 27, 29 et 31 de même que les parties plates 28, 30 et 32 guideront le bouchon hors du goulot. Comme dans les modes d'exécution précédents, l'intérieur du goulot 1 représenté dans les fig. 9 et 10 sera formé de manière à pouvoir enlever un bouchon par rotation en lui faisant parcourir entre 1/3 et 1/2 tour. D'autre part, la configuration triangulaire de l'intérieur du goulot s'étendra comme mentionné plus haut sur environ 20 mm, étant entendu qu'elle peut être augmentée ou raccourcie selon la qualité des bouchons (dureté, élasticité, ...) ou le genre de bouchons utilisés.In the embodiment of fig. 9 and 10, the neck 1 has, as in the previous embodiments, a flange 5 which will make it possible to fix a basket of wire, not shown, at its lower part and the upper part of which will be applied against a head of a cap also not shown. As shown in fig. 10, the neck is presented at its upper part in the form of an equilateral triangle, the vertices of which are rounded, as shown in 25. With respect to a circular orifice of normal configuration shown in dotted lines along line 26 in FIG. 10, the profile of the neck therefore has a succession of hollows 27 and flattened parts 28, respectively 29, 30 and 31, 32. This configuration in the form of an equilateral triangle with rounded vertices enters inside the neck according to a spiral clockwise and extends for approximately 20 mm. It is easily understood that the hollows 27, 29 and 31 each form a groove which descends inside the neck with a rotational movement in the clockwise direction. Similarly, the parts 28, 30 and 32 form guide surfaces having the same inclination as the grooves 27, 29 and 31. The configuration of the periphery 25 of the internal surface of the neck 1 is made so as to have the same surface as the normal circular configuration represented by the dotted line 26 (fig. 10). In this way, it will be possible to place inside the neck 1 of the embodiment of FIGS. 9 and 10, a plug similar to the plug normally used for normal necks with circular configuration. When the plug is in place, it will completely fill the inside of the neck, occupying the space left by the grooves 27, 29 and 31 and being pushed back by the parts 28, 30 and 32. When the plug is rotated anticlockwise, the grooves 27, 29 and 31 as well as the flat parts 28, 30 and 32 will guide the plug out of the neck. As in the previous embodiments, the inside of the neck 1 shown in FIGS. 9 and 10 will be formed so as to be able to remove a plug by rotation, making it travel between 1/3 and 1/2 turn. On the other hand, the triangular configuration of the inside of the neck will extend as mentioned above over about 20 mm, it being understood that it can be increased or shortened depending on the quality of the caps (hardness, elasticity, ...) or the kind of plugs used.

Il est évident que les goulots de bouteille décrits en regard des modes d'exécution des fig. 1 à 10 sont principalement destinés à être moulés sur des bouteilles de verre, destinées à contenir du champagne, du vin champagnisé ou du cidre pétillant et bouchées en général avec des bouchons de liège. Cependant, il est clair que les goulots qui viennent d'être décrits peuvent également être obturés par des bouchons en matière plastique souple ou en caoutchouc présentant une élasticité suffisante pour épouser étroitement toutes les rainures prévues à l'intérieur des goulots.It is obvious that the bottle necks described with regard to the embodiments of FIGS. 1 to 10 are mainly intended to be molded on glass bottles, intended to contain champagne, champagne or sparkling cider and generally corked with corks. However, it is clear that the necks which have just been described can also be closed by plugs made of flexible plastic material or rubber having sufficient elasticity to closely fit all the grooves provided inside the necks.

La fermeture de la bouteille sera prévue au moyen d'un bouchon déformable présentant une partie supérieure susceptible d'être prise dans la main de l'utilisateur. Il n'est pas nécessaire non plus que la bouteille contienne un liquide sous pression pour que son ouverture s'effectue facilement. L'homme du métier comprend aisément que la pression contenue dans une bouteille équipée d'un goulot et d'un bouchon tels que décrits ci-dessus aide et facilite la sortie du bouchon, le mouvement du poignet ne servant alors qu'à décoller les surfaces adjacentes du bouchon et de l'intérieur du goulot, puis à contrôler la sortie dudit bouchon. Par contre, dans le cas où la bouteille ne contient pas un fluide sous pression, la sortie du bouchon sera effectuée par la rotation donnée au bouchon par la main de l'utilisateur.The closure of the bottle will be provided by means of a deformable cap having an upper part capable of being taken in the hand of the user. Neither is it necessary for the bottle to contain a pressurized liquid for it to be easily opened. Those skilled in the art can easily understand that the pressure contained in a bottle equipped with a neck and a stopper as described above helps and facilitates the exit of the stopper, the movement of the wrist then only serving to take off the adjacent surfaces of the plug and the inside of the neck, then controlling the outlet of said plug. On the other hand, in the case where the bottle does not contain a fluid under pressure, the outlet of the stopper will be carried out by the rotation given to the stopper by the hand of the user.

L'idée maîtresse de l'invention consiste donc en un goulot présentant des surfaces de guidage descendant dans son intérieur selon un sens de rotation, de manière que le bouchon qui ferme la bouteille puisse être sorti sans qu'il soit nécessaire d'effectuer plusieurs rotations successives par rapport à la bouteille. Par conséquent, le bouchon devra pouvoir être sorti par une rotation de 1/4 à 1/2 tour de circonférence.The main idea of the invention therefore consists of a neck having guide surfaces descending in its interior in a direction of rotation, so that the stopper which closes the bottle can be removed without it being necessary to perform several successive rotations with respect to the bottle. Consequently, the plug must be able to be removed by a rotation of 1/4 to 1/2 turn in circumference.

7. Bottle according to claim 1, characterized by the fact that the grooves or ribs (6, 7 ; 11, 12, 13 ; 16 ; 20 ; 27, 29, 31) have a triangular section.
8. Bottle according to claim 1, characterized by the fact that the ribs (16) begin at a certain distance from the top of the neck which has a smooth inner cylindrical surface until the beginning of the ribs.
9. Bottle according to claim 1, characterized by the fact that the width of the ribs (20), measured along the circumference of the neck, increases as they descend into the neck.
10. Bottle according to claim 9, characterized by the fact that the height of the ribs (20), measured in the direction of the neck diameter, decreases as they descend into the neck.
11. Bottle according to claim 1, characterized by the fact that the neck has a cylindrical shape extending over 20 millimeters, with its diameter then increasing (fig. 5 to 10).
12. Bottle according to claim 1, characterized by the fact that the width and the height of the ribs, measured along the neck circumference and, respectively, on the neck diameter, are less then 1 mm (fig. 3, 4 ; 5, 6).
