Definitions
- the present invention relates to a stopper for a container capable of containing a fluid, and more particularly relates to such a stopper intended for use on a container filled with a sparkling drink (or carbonated drink).
- liquid drinks contain dissolved gas (such as carbon dioxide) to give them a sparkling character.
- dissolved gas such as carbon dioxide
- a user wishes to consume the drink, he opens the cap of the container, which has the effect of bringing the liquid drink into contact with the ambient (external) atmosphere.
- the partial pressure of the ambient atmosphere being low for the dissolved gas, part of the gas dissolved in the liquid beverage is released.
- the liquid drink thus loses a significant amount of dissolved gas, which reduces its sparkling character.
- the organoleptic qualities of the drink are thus irreversibly affected.
- the carbonated drink containers are fitted with a tight stopper that it is recommended to replace the neck of the container tightly as soon as the desired quantity of drink has been poured into it. a glass.
- the container When using such devices, the container is inclined with its neck facing downwards, the bottom of the container being arranged at a greater height than the neck.
- the pouring sleeve is rotated, which causes the bottom wall to translate, until the inner face of the bottom wall no longer seals off the pouring orifice of the neck.
- the drink is then pushed downward (through the neck) by the effect of gravity and the pressure inside the container.
- the liquid drink after having passed the pouring orifice, travels through the threaded connection between the stopper and the neck to go up in a direction opposite to the direction of pouring.
- the liquid beverage then travels through a peripheral passage formed between the stopper and the pouring sleeve before escaping out of the pouring sleeve to be collected in a glass.
- the document US 2,348,014 A describes an assembly comprising a container and a cap for pouring liquid out of the container without having to completely remove the cap.
- the beverage enters the threaded connection between the stopper and the neck of the container, which again is not desirable for reasons of hygiene.
- the neck of the container has a longitudinal channel on its periphery which gives it a special and complex shape.
- the document US 2013/0058595 A1 describes an assembly comprising a flexible-walled container and a stopper.
- the cap must be completely removed to pour content out of the container.
- the container is provided with a special neck with a threaded section and a long distal cylindrical section.
- the distal cylindrical section is longer than the threaded section, so that, when the neck and the stopper no longer cooperate by screwing, the stopper remains fitted onto said distal cylindrical section by means of a seal in the form of an annular lip.
- the annular seal scrapes the distal cylindrical section of the neck and thus brings back into the orifice of the neck the content which may have started to come out of the container when the cap was unscrewed.
- the document FR 2 077 957 A1 describes an assembly comprising a container and a cap, according to the preamble of claim 1.
- a problem proposed by the present invention is to design an assembly comprising a container and a cap making it possible to limit the losses of gas dissolved in a beverage contained in the container, and which is also simple and inexpensive to manufacture.
- the present invention aims to provide an assembly comprising a container and a cap which enables easier and faster dispensing of carbonated drink, even when the volume left vacant by the liquid in the container is small, and under conditions of. Improved hygiene.
- the present invention aims to provide a cap capable of being maneuvered, without special precautions, like a conventional cap without risk of deterioration.
- the invention provides an assembly according to claim 1.
- cap of such an assembly can be done either in the traditional way (by removal leading to a complete separation of the cap away from the container) or according to a use similar to that described in the documents.
- US 5,897,037 A and US 2010/0001018 A1 by an orientation of the container in which the bottom of the container is raised to a height greater than that of the neck, then the stopper is maneuvered without separation away from the container) to limit the losses of gas dissolved in the carbonated drink contained in the container. Its structure is also simple and inexpensive to manufacture.
- the first sealing means When the container is oriented to limit gas losses and the cap is moved to the pouring position, the first sealing means are moved away from the annular end curb and no longer block the pouring opening. tightly.
- the liquid contained in the container then exits through the pouring opening under the effect of gravity and the internal pressure of the container (as well as under the effect of a possible deformation of the container by clamping in the hand of the user).
- the second sealing means oppose the passage of liquid between the distal cylindrical section of the neck and the stopper in the direction of the threaded sections of the stopper and of the neck, and the liquid then passes through said at least one peripheral passage formed between the edge peripheral of the first sealing means and the peripheral skirt.
- the liquid accesses the orifice passing through the space between the first face (called the upper face) and the inner face, and exits in the form of a jet.
- the liquid does not pass over the threaded sides of the neck, so that its path has fewer recesses and less resistance for the liquid to exit from the container. Furthermore, the second sealing means opposing the passage of liquid between the cylindrical section of the neck and the stopper, the risk of drops of drink flowing along the bottle after use is reduced.
- the stopper according to the invention When the stopper according to the invention is used with a deformable container (with a flexible wall for example) containing a non-carbonated drink, a deformation of the container (by clamping in the user's hand for example) makes it possible to extract the drink in the form of a jet through the through orifice. The user can then drink “from the jet”, without his lips coming into contact with the stopper, which is appreciable for reasons of hygiene when the user does not have a glass.
- the distal cylindrical section of the neck located between the pouring orifice and the external thread of the neck, can extend along a length less than the length along which the external thread extends over the neck.
- the second sealing means may comprise an annular lip extending from and away from the peripheral skirt, and shaped so that its free end comes to bear resiliently against said cylindrical section of the neck.
- an annular lip is easy to manufacture in one piece with the peripheral skirt and provides an effective seal. The result is a reduction in the number of parts and lower manufacturing costs.
- the annular seal (O-ring for example) also provides a good seal, even if it has the drawback, compared with the annular lip, of being an additional attached part.
- the first sealing means in the closed position, may bear against the inner face of the bottom wall so as to prevent any passage of fluid between the first face (called the upper face) of the first sealing means and the inner face of the bottom wall. Satisfactory sealing is thus maintained in the closed position, even if the sealing of the pouring orifice by pressing the first sealing means on the annular end pavement was defective. And the constituent parts of the stopper can have very simple shapes that are easy to manufacture.
- the axial spacing generated by the user between the inner face of the bottom wall and the annular end curb will result, in the first axial direction, in a release of the first sealing means between the curb annular end and the inner face.
- This allows the creation of a space between the annular end sidewalk and the second face (called the lower face), and a space between the first face (called the upper face) and the interior face, and provides the conduction path allowing the passage of fluid.
- the space between the first face (called the upper face) and the inner face can be permanently provided by spacer means.
- the space between the first face (called the upper face) and the inner face being permanent, the distance between the inner face of the bottom wall and the annular end curb that the user must generate to reach the pouring position only serves to spare the space between the annular end sidewalk and the second face (called the lower face).
- the distance between the inner face of the bottom wall and the annular end pavement that must be generated by the The user is noticeably half the size. This results in unscrewing of the cap at a smaller angular amplitude, which is more comfortable for the user and limits the risks of too much unscrewing which could lead to complete separation of the cap and the container.
- the spacer means may comprise a plurality of studs extending from and away from the inner face of the bottom wall in the first axial direction, separated from each other. by spacers.
- the pads make it possible to maintain the first sealing means at a predetermined distance from the inner face of the bottom wall of the stopper, while allowing liquid to pass between them.
- the space between the first face (called the upper face) and the inner face is thus maintained in a simple and efficient manner.
- the studs can be arranged substantially in a circle and so as to come at least partly in correspondence of the annular end pavement.
- Such pads make it possible, in the closed position, to improve the pressing of the first sealing means against the annular end curb of the neck for satisfactory sealing of the pouring orifice of the neck.
- the spacer means may comprise, on the first face (called the upper face) of said first sealing means in the general form of a disc, a plurality of protuberances intended to bear on the inner face of the bottom wall and separated from each other by spacers.
- the protuberances make it possible to maintain the first sealing means at a predetermined distance from the inner face of the bottom wall of the stopper, while allowing liquid to pass between them. We thus maintain in a simple way and effective the space between the first face (called the upper face) and the inner face.
- the protuberances can be arranged substantially in a circle and so as to come at least partly in correspondence with the annular end curb.
- Such protuberances make it possible, in the closed position, to improve the pressing of the first sealing means against the annular end curb of the neck for satisfactory sealing of the pouring orifice of the neck.
- protuberances of the second variant of the second embodiment and the studs of the first variant of the second embodiment can also be used in combination.
- the first face (called the upper face) and / or the second face (called the lower face) of said first sealing means in the general form of a disc may (may) include stiffening ribs, said ribs extending along substantially radial directions.
- the ribs make it possible to reinforce the rigidity of the first sealing means in the general form of a disc in order to limit the risks of the latter being deformed by the internal pressure of the container, which deformations could cause leaks in the closed position.
- the ribs arranged on the first face (called the upper face) of the first sealing means may also have a sufficient height to play the role of spacers intended to bear on the inner face of the bottom wall, such as the previously mentioned growths.
- the first face (called the upper face) of said first sealing means in the general form of a disc can be concave.
- Such a shape makes it possible to keep for the liquid a substantially constant flow section from the periphery of the first sealing means to the through orifice, avoiding excessive braking by viscosity and limiting the risks of turbulence and gas bubble formation before liquid exits through the through hole.
- a stud can extend in the first axial direction from the first face (called upper face) of said first sealing means, its cross section gradually reducing away from the first face (called upper face) of said first sealing means.
- This stud intended to be located substantially in correspondence with the through hole in the first axial direction, allows the flow of liquid from said at least one peripheral passage to be gradually deflected in order to direct it towards the through orifice. It is in particular possible to use a conical or frustoconical stud. This nipple helps to limit the risks of turbulence and the formation of gas bubbles before the liquid exits through the through hole.
- the second face (referred to as the lower face) of said first sealing means in the general form of a disc may be convex.
- a convexity makes it possible to guide the liquid leaving the container through the pouring orifice towards said at least one peripheral passage. This limits the turbulence during the flow of the liquid, turbulence which would contribute to increasing the gas losses of the liquid extracted from the container.
- said first sealing means in the general form of a disc, an annular hollow intended to receive the annular end sidewalk. It is thus achieved, in the closed position, a nesting of the annular end sidewalk and the first sealing means.
- This cooperation of shapes provides baffles which help to improve the seal in the closed position.
- annular hollow can be provided by an annular thinning of the thickness of the first generally disc-shaped sealing means.
- annular hollow can be provided by a single annular rib or by several concentric annular ribs projecting from the second face (called the lower face) of said first sealing means in the general shape of a disc.
- the outer face of the bottom wall may be substantially planar and substantially perpendicular to the first axial direction.
- Such a shape allows the reception in support of another container (in the case of stacking, during palletization for example).

- second sealing means 15 are provided, located away from the inner face 8b of the bottom wall 8 and beyond said at least one peripheral passage 11 in the first axial direction II.
- the second sealing means 15 are intended to come, for any position of the stopper 1 between the pouring position to the closed position, in sealed contact around a cylindrical section 16 distal from the neck 5, which cylindrical section 16 distal extends from and away from the pouring hole 7 (see figures 6 , 7 , 11 , 12 , 17 , 18 , 21 and 22 ), and has a cylindrical outer surface with a circular cross section.
- the first sealing means 3 allow a passage of fluid in a conduction path comprising a space E between the annular end sidewalk 6 and the lower face 3b of the first sealing means 3, said at least one peripheral passage 11 and a space 25 between the upper face 3a of the first sealing means 3 and the internal face 8b of the bottom wall 8, said conduction path extending to the through orifice 9.
- the second sealing means 15 comprise an annular lip 17 extending from and away from the peripheral skirt 10 ( figures 1 , 8 and 16 especially).
- the annular lip 17 is shaped so that its free end 17a comes to rest resiliently all around said cylindrical section 16 distal from the neck 5 ( figures 6 , 7 , 11 , 12 , 17 and 18 ).
- the annular lip 17 is formed integrally with the stopper part 2, for example by a plastic injection process.
- the distal cylindrical section 16 situated between the pouring orifice 7 and the external thread 5a of the neck 5 extends along a length less than the length along which the external thread 5a extends over the neck. 5, as in most bottlenecks used in containers on the market.
- the peripheral skirt 10 of the plug thus extends over a short length in the first axial direction II (only a little greater than the length of the external thread 5a). All of this contributes to the simple and inexpensive formation of an assembly 100 according to the invention.
- the first sealing means 3 in the general form of a disc comprise four radial tabs 23a to 23d protruding beyond the diameter D1 of the first sealing means 3 in the form of a disc.

- the upper face 3a of said first sealing means 3 in the general form of a disc comprises eight stiffening ribs 20a to 20h, said ribs 20a to 20h extending in substantially radial directions.
- the ribs 20a to 20h also contribute to guiding the liquid towards the center of the first sealing means 3, that is to say in the direction of the through hole 9 located in correspondence ( figures 17 , 18 , 21 and 22 ). This guidance limits the risk of turbulence in the flow, and thus reduces gas losses from the liquid. A different number of ribs is however possible.
- the ribs 20a to 20h may project away from the upper face 3a at a height allowing them to (in addition) perform the same function as the spacer means 12.
- the lower face 3b of said first sealing means 3 in the general form of a disc comprises eight stiffening ribs 21a to 21h. Said ribs 21a to 21h extend in substantially radial directions. They meet at the center of the first sealing means 3, thus forming a pattern substantially in the form of an eight-pointed star.
- the ribs 21a to 21h also contribute to guiding the liquid towards the peripheral edge 3c of the first sealing means 3, that is to say by direction of the peripheral passage 11 located between the first sealing means 3 and the peripheral skirt 10 ( figures 16 and 20 especially). This guidance limits the risk of turbulence in the flow, and thus reduces gas losses from the liquid. A different number of ribs is however possible.
- the lower face 3b of said first sealing means 3 in the general form of a disc is convex.
- the upper face 3a of said first sealing means 3 in the general form of a disc is concave, and more particularly frustoconical.
- annular hollow 22 intended to receive the annular end pavement 6 has been formed on the lower face 3b of said first sealing means 3 in the general form of a disc.
- This annular hollow 22 is defined by a crown lying between two concentric annular ribs 22a and 22b.
- the annular hollow 22 is maintained substantially in correspondence with the annular end curb 6 of the neck 5 by the radial tabs 23a to 23d. It is nevertheless possible to provide an annular hollow while retaining only one of the annular ribs 22a and 22b.
- the outer face 8a of the bottom wall 8 is substantially planar and substantially perpendicular to the first axial direction II (which coincides with the axis of elongation of the container 4) to facilitate a stacking of several containers 4 fitted with a cap 1.
- the second sealing means 15 are located, in the first axial direction I-I, between the internal face 8b of the bottom wall 8 and the internal thread 10a.
- first sealing means 3 of the figures 3 and 4 can be used in combination with cap part 2 of the figure 19 , with or without providing spacer means 12.
- the spacer means 12 may comprise studs 13 (on the inner face 8b) and / or protuberances 14 (on the upper face 3a).
- the stopper 1 further comprises a closure element 26 sealingly closing the through orifice 9 to prevent the penetration of impurities into the stopper 1 when it is not in use.
- the closure element 26 comprises a flange 26a, substantially in the form of a disc for example, provided with a protuberance 26b.
- the protuberance 26b is shaped so as to be able to engage in a reversible manner in force in the through orifice 9 (by clipping or snap-fastening, for example) in order to close it in a sealed manner.

Description
La présente invention concerne un bouchon pour conteneur apte à contenir un fluide, et concerne plus particulièrement un tel bouchon destiné à être utilisé sur un conteneur rempli d'une boisson pétillante (ou boisson gazeuse).The present invention relates to a stopper for a container capable of containing a fluid, and more particularly relates to such a stopper intended for use on a container filled with a sparkling drink (or carbonated drink).
De nombreuses boissons liquides contiennent du gaz dissout (tel que du dioxyde de carbone) pour leur conférer un caractère pétillant. Lorsqu'un utilisateur souhaite consommer la boisson, il ouvre le bouchon du conteneur, ce qui a pour effet de mettre la boisson liquide au contact de l'atmosphère ambiante (extérieure). La pression partielle de l'atmosphère ambiante étant faible pour le gaz dissout, une partie du gaz dissout dans la boisson liquide est libérée. La boisson liquide perd ainsi une quantité importante de gaz dissout, ce qui diminue son caractère pétillant. Les qualités organoleptiques de la boisson sont ainsi irréversiblement affectées.Many liquid drinks contain dissolved gas (such as carbon dioxide) to give them a sparkling character. When a user wishes to consume the drink, he opens the cap of the container, which has the effect of bringing the liquid drink into contact with the ambient (external) atmosphere. The partial pressure of the ambient atmosphere being low for the dissolved gas, part of the gas dissolved in the liquid beverage is released. The liquid drink thus loses a significant amount of dissolved gas, which reduces its sparkling character. The organoleptic qualities of the drink are thus irreversibly affected.
Pour limiter la perte de gaz dissout dans la boisson liquide (dégazéification), les conteneurs de boissons gazeuses sont munis d'un bouchon étanche qu'il est recommandé de replacer sur le goulot du conteneur de façon étanche aussitôt la quantité de boisson souhaitée versée dans un verre.To limit the loss of gas dissolved in the liquid drink (degassing), the carbonated drink containers are fitted with a tight stopper that it is recommended to replace the neck of the container tightly as soon as the desired quantity of drink has been poured into it. a glass.
Mais même après que le conteneur ait été refermé, du gaz dissout dans la boisson liquide se libère dans le volume du conteneur laissé libre par le volume de boisson consommé, et ce jusqu'à atteinte d'une pression d'équilibre entre le gaz contenu dans la phase gazeuse et dans la phase liquide (boisson) contenues dans le conteneur.But even after the container has been closed, gas dissolved in the liquid drink is released in the volume of the container left free by the volume of drink consumed, until an equilibrium pressure is reached between the gas contained in the gas phase and in the liquid phase (drink) contained in the container.
Lors de l'ouverture suivante du conteneur, le gaz passé en phase gazeuse s'échappera à nouveau. Après rebouchage du conteneur, un nouvel équilibre se créera encore par libération d'une partie du gaz dissout hors de la boisson liquide. Ainsi, au fur et à mesure de l'ouverture de son conteneur, une boisson gazeuse perd inexorablement de plus en plus le gaz qui y était dissout et voit en conséquence ses qualités organoleptiques (et à tout le moins son caractère pétillant) se dégrader.The next time the container is opened, the gas that has passed into the gaseous phase will escape again. After recapping the container, a new equilibrium will be created again by releasing part of the dissolved gas out of the liquid beverage. Thus, as its container is opened, a carbonated drink inexorably loses more and more of the gas which was dissolved therein and consequently sees its organoleptic qualities (and at least its sparkling character) deteriorate.
Pour limiter la libération de gaz dissout hors de la boisson liquide, on connaît des documents
- une paroi de fond à face extérieure et face intérieure, munie d'un orifice traversant,
- une jupe périphérique se développant depuis et à l'écart de la face intérieure de la paroi de fond selon une première direction axiale,
- un manchon de versage venant recouvrir le bouchon en étant couplé en rotation à ce dernier, ledit manchon de versage étant destiné à être en contact étanche à sa base avec une collerette du conteneur.
- a bottom wall with an exterior face and an interior face, provided with a through orifice,
- a peripheral skirt developing from and away from the inner face of the bottom wall in a first axial direction,
- a pouring sleeve covering the stopper while being coupled in rotation to the latter, said pouring sleeve being intended to be in sealed contact at its base with a collar of the container.
Lors de l'utilisation de tels dispositifs, le conteneur est incliné avec son goulot orienté vers le bas, le fond du conteneur étant disposé à une hauteur plus importante que le goulot. Le manchon de versage est mis en rotation, ce qui entraîne une translation de la paroi de fond, jusqu'à ce que la face intérieure de la paroi de fond n'obture plus de façon étanche l'orifice de versage du goulot. La boisson est alors poussée vers le bas (à travers le goulot) par l'effet de la gravité et de la pression intérieure du conteneur. La boisson liquide, après avoir franchi l'orifice de versage, chemine à travers la liaison filetée entre le bouchon et le goulot pour remonter dans un sens inverse au sens de versage. La boisson liquide chemine ensuite dans un passage périphérique ménagé entre le bouchon et le manchon de versage avant de s'échapper hors du manchon de versage pour être recueillie dans un verre.When using such devices, the container is inclined with its neck facing downwards, the bottom of the container being arranged at a greater height than the neck. The pouring sleeve is rotated, which causes the bottom wall to translate, until the inner face of the bottom wall no longer seals off the pouring orifice of the neck. The drink is then pushed downward (through the neck) by the effect of gravity and the pressure inside the container. The liquid drink, after having passed the pouring orifice, travels through the threaded connection between the stopper and the neck to go up in a direction opposite to the direction of pouring. The liquid beverage then travels through a peripheral passage formed between the stopper and the pouring sleeve before escaping out of the pouring sleeve to be collected in a glass.

Un problème proposé par la présente invention est de concevoir un ensemble comprenant un conteneur et un bouchon permettant de limiter les pertes de gaz dissout dans une boisson contenue dans le conteneur, et qui soit en outre simple et peu onéreux à fabriquer.A problem proposed by the present invention is to design an assembly comprising a container and a cap making it possible to limit the losses of gas dissolved in a beverage contained in the container, and which is also simple and inexpensive to manufacture.
Simultanément, la présente invention vise à procurer un ensemble comprenant un conteneur et un bouchon qui permette une distribution plus facile et plus rapide de boisson gazeuse, même lorsque le volume laissé vacant par le liquide dans le conteneur est faible, et dans des conditions d'hygiène améliorées.Selon un autre aspect, la présente invention vise à fournir un bouchon capable d'être manœuvré, sans précautions particulières, comme un bouchon classique sans risque de détérioration.At the same time, the present invention aims to provide an assembly comprising a container and a cap which enables easier and faster dispensing of carbonated drink, even when the volume left vacant by the liquid in the container is small, and under conditions of. Improved hygiene. According to another aspect, the present invention aims to provide a cap capable of being maneuvered, without special precautions, like a conventional cap without risk of deterioration.
Pour atteindre ces objets ainsi que d'autres, l'invention propose un ensemble selon la revendication 1.To achieve these and other objects, the invention provides an assembly according to
L'utilisation du bouchon d'un tel ensemble peut se faire indifféremment de façon traditionnelle (par retrait menant à une séparation complète du bouchon à l'écart du conteneur) ou selon une utilisation similaire à celle décrite dans les documents
Lorsque le conteneur est orienté pour limiter les pertes de gaz et que le bouchon est déplacé en position de versage, les premiers moyens d'étanchéité sont déplacés à l'écart du trottoir d'extrémité annulaire et n'obturent plus l'orifice de versage de façon étanche. Le liquide contenu dans le conteneur sort alors par l'orifice de versage sous l'effet de la gravité et de la pression interne du conteneur (ainsi que sous l'effet d'une éventuelle déformation du conteneur par serrage dans la main de l'utilisateur). Les deuxièmes moyens d'étanchéité s'opposent au passage de liquide entre le tronçon cylindrique distal du goulot et le bouchon en direction des tronçons filetés du bouchon et du goulot, et le liquide transite ensuite par ledit au moins un passage périphérique ménagé entre le bord périphérique des premiers moyens d'étanchéité et la jupe périphérique. Le liquide accède ensuite à l'orifice traversant par l'espace entre la première face (dite face supérieure) et la face intérieure, et sort sous la forme d'un jet.When the container is oriented to limit gas losses and the cap is moved to the pouring position, the first sealing means are moved away from the annular end curb and no longer block the pouring opening. tightly. The liquid contained in the container then exits through the pouring opening under the effect of gravity and the internal pressure of the container (as well as under the effect of a possible deformation of the container by clamping in the hand of the user). The second sealing means oppose the passage of liquid between the distal cylindrical section of the neck and the stopper in the direction of the threaded sections of the stopper and of the neck, and the liquid then passes through said at least one peripheral passage formed between the edge peripheral of the first sealing means and the peripheral skirt. The liquid then accesses the orifice passing through the space between the first face (called the upper face) and the inner face, and exits in the form of a jet.
Le liquide ne transite pas sur les flancs filetés du goulot, de sorte que son parcours présente moins de recoins et une résistance moindre pour la sortie du liquide hors du conteneur. Par ailleurs, les deuxièmes moyens d'étanchéité s'opposant au passage de liquide entre le tronçon cylindrique du goulot et le bouchon, le risque de gouttes de boisson coulant le long de la bouteille après usage est réduit.The liquid does not pass over the threaded sides of the neck, so that its path has fewer recesses and less resistance for the liquid to exit from the container. Furthermore, the second sealing means opposing the passage of liquid between the cylindrical section of the neck and the stopper, the risk of drops of drink flowing along the bottle after use is reduced.
Lorsque le bouchon selon l'invention est utilisé avec un conteneur déformable (avec une paroi souple par exemple) contenant une boisson non gazeuse, une déformation du conteneur (par serrage dans la main de l'utilisateur par exemple) permet d'extraire la boisson sous la forme d'un jet à travers l'orifice traversant. L'utilisateur peut alors boire « au jet », sans que ses lèvres n'entrent en contact avec le bouchon, ce qui est appréciable pour des raisons d'hygiène lorsque l'utilisateur ne dispose pas d'un verre.When the stopper according to the invention is used with a deformable container (with a flexible wall for example) containing a non-carbonated drink, a deformation of the container (by clamping in the user's hand for example) makes it possible to extract the drink in the form of a jet through the through orifice. The user can then drink “from the jet”, without his lips coming into contact with the stopper, which is appreciable for reasons of hygiene when the user does not have a glass.
Avantageusement, le tronçon cylindrique distal du goulot, situé entre l'orifice de versage et le filetage extérieur du goulot, peut s'étendre selon une longueur inférieure à la longueur selon laquelle s'étend le filetage extérieur sur le goulot.Advantageously, the distal cylindrical section of the neck, located between the pouring orifice and the external thread of the neck, can extend along a length less than the length along which the external thread extends over the neck.
Cela permet de former un ensemble selon l'invention de façon simple et peu onéreuse :
- en utilisant de façon économique la majeure partie des conteneurs existants sur le marché, qui comportent généralement un goulot pourvu, entre son orifice de versage et son filetage extérieur, d'un tronçon cylindrique distal s'étendant selon une longueur inférieure à la longueur selon laquelle s'étend le filetage extérieur sur le goulot,
- en utilisant un bouchon comportant une jupe périphérique de longueur réduite selon la première direction axiale, ce qui limite les coûts de matière.
- by economically using the major part of the existing containers on the market, which generally comprise a neck provided, between its pouring orifice and its external thread, with a distal cylindrical section extending along a length less than the length along which the external thread extends over the neck,
- by using a plug comprising a peripheral skirt of reduced length in the first axial direction, which limits material costs.
De préférence, les deuxièmes moyens d'étanchéité peuvent comprendre une lèvre annulaire s'étendant depuis et à l'écart de la jupe périphérique, et conformée pour que son extrémité libre vienne en appui élastique contre ledit tronçon cylindrique du goulot. Une telle lèvre annulaire est facile à fabriquer d'une pièce avec la jupe périphérique et procure une étanchéité efficace. Il en résulte une réduction du nombre de pièces et des coûts de fabrication amoindris.Preferably, the second sealing means may comprise an annular lip extending from and away from the peripheral skirt, and shaped so that its free end comes to bear resiliently against said cylindrical section of the neck. Such an annular lip is easy to manufacture in one piece with the peripheral skirt and provides an effective seal. The result is a reduction in the number of parts and lower manufacturing costs.
En alternative, on peut prévoir que :
- la jupe périphérique comprend une gorge annulaire intérieure, ladite gorge annulaire intérieure étant située au-delà dudit au moins un passage périphérique à l'écart de la paroi de fond selon la première direction axiale,
- les deuxièmes moyens d'étanchéité comprennent un joint annulaire, rapporté dans ladite gorge annulaire intérieure, et conformé pour venir en appui élastique contre ledit tronçon cylindrique du goulot.
- the peripheral skirt comprises an internal annular groove, said internal annular groove being located beyond said at least one peripheral passage away from the bottom wall in the first axial direction,
- the second sealing means comprise an annular seal, fitted in said inner annular groove, and shaped to come into elastic abutment against said cylindrical section of the neck.
Le joint annulaire (torique par exemple) procure également une bonne étanchéité, même s'il présente l'inconvénient, par rapport à la lèvre annulaire, d'être une pièce rapportée supplémentaire.The annular seal (O-ring for example) also provides a good seal, even if it has the drawback, compared with the annular lip, of being an additional attached part.
Dans un premier mode de réalisation, en position d'obturation, les premiers moyens d'étanchéité peuvent être en appui contre la face intérieure de la paroi de fond de façon à empêcher tout passage de fluide entre la première face (dite face supérieure) des premiers moyens d'étanchéité et la face intérieure de la paroi de fond. On maintient ainsi une étanchéité satisfaisante en position d'obturation, et ce même si l'obturation de l'orifice de versage par appui des premiers moyens d'étanchéité sur le trottoir d'extrémité annulaire était défectueuse. Et les éléments constitutifs du bouchon peuvent avoir des formes très simples et faciles à fabriquer.In a first embodiment, in the closed position, the first sealing means may bear against the inner face of the bottom wall so as to prevent any passage of fluid between the first face (called the upper face) of the first sealing means and the inner face of the bottom wall. Satisfactory sealing is thus maintained in the closed position, even if the sealing of the pouring orifice by pressing the first sealing means on the annular end pavement was defective. And the constituent parts of the stopper can have very simple shapes that are easy to manufacture.
En position de versage, l'écartement axial généré par l'utilisateur entre la face intérieure de la paroi de fond et le trottoir d'extrémité annulaire résultera, selon la première direction axiale, en une libération des premiers moyens d'étanchéité entre le trottoir d'extrémité annulaire et la face intérieure. Cela autorise la création d'un espace entre le trottoir d'extrémité annulaire et la deuxième face (dite face inférieure), et d'un espace entre la première face (dite face supérieure) et la face intérieure, et procure le chemin de conduction autorisant le passage de fluide.In the pouring position, the axial spacing generated by the user between the inner face of the bottom wall and the annular end curb will result, in the first axial direction, in a release of the first sealing means between the curb annular end and the inner face. This allows the creation of a space between the annular end sidewalk and the second face (called the lower face), and a space between the first face (called the upper face) and the interior face, and provides the conduction path allowing the passage of fluid.
Dans un deuxième mode de réalisation, l'espace entre la première face (dite face supérieure) et la face intérieure peut être ménagé en permanence par des moyens d'entretoise. L'espace entre la première face (dite face supérieure) et la face intérieure étant permanent, l'écartement entre la face intérieure de la paroi de fond et le trottoir d'extrémité annulaire que doit générer l'utilisateur pour parvenir en position de versage ne sert plus qu'à ménager l'espace entre le trottoir d'extrémité annulaire et la deuxième face (dite face inférieure). Ainsi, pour parvenir en position de versage à un débit sensiblement identique au débit qui serait obtenu dans le cadre du premier mode de réalisation, l'écartement entre la face intérieure de la paroi de fond et le trottoir d'extrémité annulaire que doit générer l'utilisateur est sensiblement deux fois moins grand. Cela se traduit par un dévissage du bouchon selon une amplitude angulaire moindre, ce qui est plus confortable pour l'utilisateur et limite les risques d'un dévissage trop important pouvant mener à une séparation complète du bouchon et du conteneur.In a second embodiment, the space between the first face (called the upper face) and the inner face can be permanently provided by spacer means. The space between the first face (called the upper face) and the inner face being permanent, the distance between the inner face of the bottom wall and the annular end curb that the user must generate to reach the pouring position only serves to spare the space between the annular end sidewalk and the second face (called the lower face). Thus, in order to reach the pouring position at a flow rate substantially identical to the flow rate which would be obtained in the context of the first embodiment, the distance between the inner face of the bottom wall and the annular end pavement that must be generated by the The user is noticeably half the size. This results in unscrewing of the cap at a smaller angular amplitude, which is more comfortable for the user and limits the risks of too much unscrewing which could lead to complete separation of the cap and the container.
Dans une première variante du deuxième mode de réalisation, les moyens d'entretoise peuvent comprendre une pluralité de plots s'étendant depuis et à l'écart de la face intérieure de la paroi de fond selon la première direction axiale, séparés les uns des autres par des espaces intercalaires. Les plots permettent de maintenir les premiers moyens d'étanchéité à une distance prédéterminée de la face intérieure de la paroi de fond du bouchon, tout en autorisant le passage de liquide entre eux. On maintient ainsi de façon simple et efficace l'espace entre la première face (dite face supérieure) et la face intérieure.In a first variant of the second embodiment, the spacer means may comprise a plurality of studs extending from and away from the inner face of the bottom wall in the first axial direction, separated from each other. by spacers. The pads make it possible to maintain the first sealing means at a predetermined distance from the inner face of the bottom wall of the stopper, while allowing liquid to pass between them. The space between the first face (called the upper face) and the inner face is thus maintained in a simple and efficient manner.
Avantageusement, des plots peuvent être disposés sensiblement en cercle et de façon à venir au moins en partie en correspondance du trottoir d'extrémité annulaire. De tels plots permettent, en position d'obturation, d'améliorer le pressage des premiers moyens d'étanchéité contre le trottoir d'extrémité annulaire du goulot pour une obturation satisfaisante de l'orifice de versage du goulot.Advantageously, the studs can be arranged substantially in a circle and so as to come at least partly in correspondence of the annular end pavement. Such pads make it possible, in the closed position, to improve the pressing of the first sealing means against the annular end curb of the neck for satisfactory sealing of the pouring orifice of the neck.
Dans une deuxième variante du deuxième mode de réalisation, les moyens d'entretoise peuvent comprendre, sur la première face (dite face supérieure) desdits premiers moyens d'étanchéité en forme générale de disque, une pluralité d'excroissances destinées à venir en appui sur la face intérieure de la paroi de fond et séparées les unes des autres par des espaces intercalaires. Les excroissances permettent de maintenir les premiers moyens d'étanchéité à une distance prédéterminée de la face intérieure de la paroi de fond du bouchon, tout en autorisant le passage de liquide entre elles. On maintient ainsi de façon simple et efficace l'espace entre la première face (dite face supérieure) et la face intérieure.In a second variant of the second embodiment, the spacer means may comprise, on the first face (called the upper face) of said first sealing means in the general form of a disc, a plurality of protuberances intended to bear on the inner face of the bottom wall and separated from each other by spacers. The protuberances make it possible to maintain the first sealing means at a predetermined distance from the inner face of the bottom wall of the stopper, while allowing liquid to pass between them. We thus maintain in a simple way and effective the space between the first face (called the upper face) and the inner face.
Avantageusement, des excroissances peuvent être disposées sensiblement en cercle et de façon à venir au moins en partie en correspondance du trottoir d'extrémité annulaire. De telles excroissances permettent, en position d'obturation, d'améliorer le pressage des premiers moyens d'étanchéité contre le trottoir d'extrémité annulaire du goulot pour une obturation satisfaisante de l'orifice de versage du goulot.Advantageously, the protuberances can be arranged substantially in a circle and so as to come at least partly in correspondence with the annular end curb. Such protuberances make it possible, in the closed position, to improve the pressing of the first sealing means against the annular end curb of the neck for satisfactory sealing of the pouring orifice of the neck.
Il doit être noté que les excroissances de la deuxième variante du deuxième mode de réalisation et les plots de la première variante du deuxième mode de réalisation peuvent également être utilisés en combinaison.It should be noted that the protuberances of the second variant of the second embodiment and the studs of the first variant of the second embodiment can also be used in combination.
De préférence, la première face (dite face supérieure) et/ou la deuxième face (dite face inférieure) desdits premiers moyens d'étanchéité en forme générale de disque peut (peuvent) comporter des nervures de rigidification, lesdites nervures s'étendant selon des directions sensiblement radiales. Les nervures permettent de renforcer la rigidité des premiers moyens d'étanchéité en forme générale de disque pour limiter les risques de déformations de ceux-ci par la pression intérieure du conteneur, lesquelles déformations pourraient occasionner des fuites en position d'obturation. A noter que les nervures disposées sur la première face (dite face supérieure) des premiers moyens d'étanchéité peuvent également présenter une hauteur suffisante pour jouer un rôle d'entretoises destinées à venir en appui sur la face intérieure de la paroi de fond, comme les excroissances précédemment mentionnées.Preferably, the first face (called the upper face) and / or the second face (called the lower face) of said first sealing means in the general form of a disc may (may) include stiffening ribs, said ribs extending along substantially radial directions. The ribs make it possible to reinforce the rigidity of the first sealing means in the general form of a disc in order to limit the risks of the latter being deformed by the internal pressure of the container, which deformations could cause leaks in the closed position. Note that the ribs arranged on the first face (called the upper face) of the first sealing means may also have a sufficient height to play the role of spacers intended to bear on the inner face of the bottom wall, such as the previously mentioned growths.
Avantageusement, la première face (dite face supérieure) desdits premiers moyens d'étanchéité en forme générale de disque peut être concave.Advantageously, the first face (called the upper face) of said first sealing means in the general form of a disc can be concave.
Une telle forme (avantageusement conique ou tronconique) permet de conserver pour le liquide une section d'écoulement sensiblement constante depuis la périphérie des premiers moyens d'étanchéité jusqu'à l'orifice traversant, évitant un freinage excessif par viscosité et limitant les risques de turbulences et de formation de bulles de gaz avant la sortie du liquide par le trou traversant.Such a shape (advantageously conical or frustoconical) makes it possible to keep for the liquid a substantially constant flow section from the periphery of the first sealing means to the through orifice, avoiding excessive braking by viscosity and limiting the risks of turbulence and gas bubble formation before liquid exits through the through hole.
Avantageusement, un téton peut s'étendre selon la première direction axiale depuis la première face (dite face supérieure) desdits premiers moyens d'étanchéité, sa section transversale se réduisant progressivement à l'écart de la première face (dite face supérieure) desdits premiers moyens d'étanchéité. Ce téton, destiné à être situé sensiblement en correspondance du trou traversant selon la première direction axiale, permet de dévier de façon progressive le flux de liquide en provenance dudit au moins un passage périphérique pour le diriger vers l'orifice traversant. On peut notamment avoir recours à un téton conique ou tronconique. Ce téton contribue à limiter les risques de turbulences et de formation de bulles de gaz avant la sortie du liquide par le trou traversant.Advantageously, a stud can extend in the first axial direction from the first face (called upper face) of said first sealing means, its cross section gradually reducing away from the first face (called upper face) of said first sealing means. This stud, intended to be located substantially in correspondence with the through hole in the first axial direction, allows the flow of liquid from said at least one peripheral passage to be gradually deflected in order to direct it towards the through orifice. It is in particular possible to use a conical or frustoconical stud. This nipple helps to limit the risks of turbulence and the formation of gas bubbles before the liquid exits through the through hole.
De préférence, la deuxième face (dite face inférieure) desdits premiers moyens d'étanchéité en forme générale de disque peut être convexe. Une telle convexité permet de guider le liquide sortant du conteneur par l'orifice de versage vers ledit au moins un passage périphérique. On limite ainsi les turbulences lors de l'écoulement du liquide, turbulences qui contribueraient à augmenter les pertes en gaz du liquide extrait hors du conteneur.Preferably, the second face (referred to as the lower face) of said first sealing means in the general form of a disc may be convex. Such a convexity makes it possible to guide the liquid leaving the container through the pouring orifice towards said at least one peripheral passage. This limits the turbulence during the flow of the liquid, turbulence which would contribute to increasing the gas losses of the liquid extracted from the container.
Avantageusement, il peut être ménagé, sur la deuxième face (dite face inférieure) desdits premiers moyens d'étanchéité en forme générale de disque, un creux annulaire destiné à recevoir le trottoir d'extrémité annulaire. Il est ainsi réalisé, en position d'obturation, une imbrication du trottoir d'extrémité annulaire et des premiers moyens d'étanchéité. Cette coopération de formes procure des chicanes qui contribuent à améliorer l'étanchéité en position d'obturation.Advantageously, there may be provided on the second face (called the lower face) of said first sealing means in the general form of a disc, an annular hollow intended to receive the annular end sidewalk. It is thus achieved, in the closed position, a nesting of the annular end sidewalk and the first sealing means. This cooperation of shapes provides baffles which help to improve the seal in the closed position.
Il doit être noté que le creux annulaire peut être procuré par un amincissement annulaire de l'épaisseur des premiers moyens d'étanchéité en forme générale de disque. En alternative (ou en complément), le creux annulaire peut être procuré par une unique nervure annulaire ou par plusieurs nervures annulaires concentriques faisant saillie sur la deuxième face (dite face inférieure) desdits premiers moyens d'étanchéité en forme générale de disque.It should be noted that the annular hollow can be provided by an annular thinning of the thickness of the first generally disc-shaped sealing means. As an alternative (or in addition), the annular hollow can be provided by a single annular rib or by several concentric annular ribs projecting from the second face (called the lower face) of said first sealing means in the general shape of a disc.
De préférence, la face extérieure de la paroi de fond peut être sensiblement plane et sensiblement perpendiculaire à la première direction axiale. Une telle forme permet la réception en appui d'un autre conteneur (cas d'un empilage, lors d'une palettisation par exemple).Preferably, the outer face of the bottom wall may be substantially planar and substantially perpendicular to the first axial direction. Such a shape allows the reception in support of another container (in the case of stacking, during palletization for example).
De préférence, pour éviter la pénétration d'impuretés dans le bouchon, on peut prévoir un élément d'obturation apte à obturer de façon étanche l'orifice traversant par un engagement en force réversible dans l'orifice traversant.Preferably, to prevent the penetration of impurities into the stopper, there can be provided a closure element capable of sealing off the through orifice by a reversible force engagement in the through orifice.

Par ailleurs, les excroissances 14 peuvent adopter dans le cadre de la deuxième variante du deuxième mode de réalisation ou dans le cadre du troisième mode de réalisation, une forme identique ou similaire à celle des plots 13, et inversement pour les plots 13 dans le cadre de la première variante du deuxième mode de réalisation.Furthermore, the
Dans tous les modes de réalisation on prévoit des deuxièmes moyens d'étanchéité 15, situés à l'écart de la face intérieure 8b de la paroi de fond 8 et au-delà dudit au moins un passage périphérique 11 selon la première direction axiale I-I. Les deuxièmes moyens d'étanchéité 15 sont destinés à venir, pour toute position du bouchon 1 entre la position de versage jusqu'en position d'obturation, en contact étanche autour d'un tronçon cylindrique 16 distal du goulot 5, lequel tronçon cylindrique 16 distal s'étend depuis et à l'écart de l'orifice de versage 7 (voir

un passage périphérique 11 à l'écart de la paroi de fond 8 selon la première direction axiale I-I, - les deuxièmes moyens d'étanchéité 15 comprennent un joint annulaire 19 (torique en l'espèce), rapporté dans ladite gorge annulaire intérieure 18, et conformé pour venir en appui élastique contre ledit tronçon cylindrique 16 distal du goulot 5.

peripheral skirt 10 comprises an internalannular groove 18, said internalannular groove 18 being located beyond said at least oneperipheral passage 11 away from thebottom wall 8 in the first axial direction II, - the second sealing means 15 comprise an annular seal 19 (O-ring in this case), fitted in said internal
annular groove 18, and shaped to come into elastic abutment against saidcylindrical section 16 distal of theneck 5.
Dans tous les modes de réalisation, le tronçon cylindrique 16 distal situé entre l'orifice de versage 7 et le filetage extérieur 5a du goulot 5 s'étend selon une longueur inférieure à la longueur selon laquelle s'étend le filetage extérieur 5a sur le goulot 5, comme dans la plupart des goulots utilisés dans les conteneurs présents sur le marché. Pour recevoir convenablement le filetage extérieur 5a et le tronçon cylindrique 16, la jupe périphérique 10 du bouchon s'étend ainsi selon une longueur peu importante selon la première direction axiale I-I (seulement un peu supérieure à la longueur du filetage extérieur 5a).

Lors de l'assemblage de la partie de bouchon 2 et des premiers moyens d'étanchéité 3 pour former le bouchon 1, les languettes radiales 23a à 23d et/ou les deuxièmes moyens d'étanchéité 15 se déforment élastiquement pour permettre la pénétration des premiers moyens d'étanchéité 3 entre la face intérieure 8b et les deuxièmes moyens d'étanchéité 15 (selon la première direction axiale I-I). Les languettes radiales 23a à 23d sont reçues avec un faible jeu radial à l'intérieur de la jupe périphérique 10 pour centrer de façon satisfaisante les premiers moyens d'étanchéité 3 pour un bon positionnement face au trottoir d'extrémité annulaire 6 du goulot 5.During the assembly of the
En alternative ou en complément des languettes radiales 23a à 23d, on peut prévoir, sur le tronçon de jupe périphérique 10 présentant un diamètre intérieur D2, une pluralité de tétons radiaux (au moins trois ou quatre de préférence) prenant par exemple naissance simultanément sur la face intérieure 8b et sur la jupe périphérique 10, les tétons radiaux définissant entre eux un diamètre égal ou peu inférieur à D1.

Dans tous les modes de réalisation illustrés sur les figures, on observe que :
- la jupe périphérique 10 comporte un filetage intérieur 10a apte à coopérer par vissage avec un filetage extérieur 5a du goulot 5 du conteneur 4,
- le tronçon cylindrique 16 du
goulot 5, autour duquel les deuxièmes moyens d'étanchéité 15 sont destinés à venir en contact étanche en positions de versage et d'obturation du bouchon, est situé entre l'orifice de versage 7 et le filetage extérieur 5a du goulot 5.

L'engagement en force peut être dimensionné de façon à pouvoir résister à une pression interne du conteneur 4 pouvant aller jusqu'à 6 bars (par élévation de la température et/ou agitation du liquide par exemple). De cette façon, on limite les risques d'une éjection fortuite de l'élément obturateur 26 dès que le bouchon 1 a été disposé en position de versage par un utilisateur. L'utilisateur doit nécessairement procéder à un retrait volontaire de l'élément d'obturation 26 pour extraire de la boisson hors du conteneur 4 à travers l'orifice traversant 9.The force engagement can be dimensioned so as to be able to withstand an internal pressure of the
L'élément d'obturation 26 peut avoir une forme facilitant sa préhension par un utilisateur. En l'espèce, l'élément obturateur 26 comporte une dépouille latérale sur une partie de la hauteur du flasque 26a pour faciliter l'engagement d'un ongle entre le flasque 26a et la face extérieure 8a de la paroi de fond 8.The

Si un utilisateur souhaite retirer le bouchon 1 comme un bouchon conventionnel, il peut dévisser le bouchon 1 jusqu'à séparation complète du bouchon 1 et du conteneur 4. Lors de cette séparation, les premiers moyens d'étanchéité 3 en forme de disque sont maintenus captifs à proximité de la face intérieure 8b par la coopération des languettes radiales 23a à 23d avec les deuxièmes moyens d'étanchéité 15. L'utilisateur peut alors orienter le conteneur 4 de façon à provoquer un écoulement de la boisson liquide à travers l'orifice de versage 7 vers l'extérieur.If a user wishes to remove the
Lorsque l'utilisateur a fini de se servir, il rapporte le bouchon 1 par vissage sur le goulot 5. Les premiers moyens d'étanchéité 3 en forme de disque étant maintenus captifs sont automatiquement disposés en bonne place en correspondance du trottoir d'extrémité annulaire 6 du goulot 5. L'utilisateur peut alors poursuivre le vissage jusqu'à amener le bouchon 1 en position d'obturation.When the user has finished using, he brings the
L'utilisateur peut en revanche souhaiter provoquer un écoulement de la boisson du conteneur 4 tout en limitant la baisse en concentration du gaz dissout dans la boisson restant dans le conteneur 4, et ce afin d'en préserver les propriétés organoleptiques.On the other hand, the user may wish to cause the drink to flow from the
Pour ce faire, l'utilisateur commence par orienter le conteneur 4 avec son goulot vers le bas, comme illustré sur les

Il est alors créé un écart axial selon la première direction axiale I-I entre la face intérieure 8b de la paroi de fond 8 et le trottoir d'extrémité annulaire 6 du goulot 5.An axial gap is then created in the first axial direction I-I between the
Dans le cadre du premier mode de réalisation (
- un espace E axial entre le trottoir d'extrémité annulaire 6 et la
face inférieure 3b des premiers moyensd'étanchéité 3, un espace 25 axial entrela face supérieure 3a des premiers moyensd'étanchéité 3 et laface intérieure 8b de la paroi de fond 8.
- an axial space E between the
annular end curb 6 and thelower face 3b of the first sealing means 3, - an
axial space 25 between theupper face 3a of the first sealing means 3 and theinternal face 8b of thebottom wall 8.
Les espaces E et 25 étant en communication avec le passage périphérique 11, il est ainsi autorisé par les premiers moyens d'étanchéité 3 un passage de fluide dans un chemin de conduction comprenant l'espace E, le passage périphérique 11 et l'espace 25, ledit chemin de conduction s'étendant jusqu'à l'orifice traversant 9 pour permettre au liquide de sortir.The spaces E and 25 being in communication with the

Là encore, les espaces E et 25 étant en communication avec le passage périphérique 11, il est ainsi autorisé par les premiers moyens d'étanchéité 3 un passage de fluide dans un chemin de conduction comprenant l'espace E, le passage périphérique 11 et l'espace 25, ledit chemin de conduction s'étendant jusqu'à l'orifice traversant 9 pour permettre au liquide de sortir.Here again, the spaces E and 25 being in communication with the
Les deuxièmes moyens d'étanchéité 15 assurent un contact étanche entre la jupe périphérique 10 et le tronçon cylindrique 16 du goulot 5. Ainsi, le liquide ne peut pas pénétrer dans les filetages 10a et 5a. Les filetages sont ainsi préservés de tout contact avec la boisson. Cela limite les risques de développement de bactéries qui pourraient se retrouver dans le verre de l'utilisateur. Et cela évite également un encrassement des filetages 10a et 5a pouvant rendre difficile la manœuvre en rotation du bouchon 1 par rapport au goulot 5, surtout si la boisson contient du sucre.The second sealing means 15 provide sealed contact between the
Après sa sortie à travers l'orifice de versage 7, le liquide chemine par le passage périphérique 11 ménagé en permanence entre le bord périphérique 3c des premiers moyens d'étanchéité 3 et la jupe périphérique 10, puis, après être passé par les espaces laissés vacants par les moyens d'entretoise 12 (espaces intercalaires 13a ménagés entre les plots 13) dans le cas de la
Lorsque la quantité de boisson désirée a été versée hors du conteneur 4, l'utilisateur effectue un mouvement de rotation relative entre le bouchon 1 et le conteneur 4 par lequel le bouchon 1 est amené dans la position d'obturation illustrée sur les
