Abstract

The present invention pertains to a method for filling a carboy with liquid foodstuff designed to be installed in a fountain for distribution of such a liquid. The liquid is introduced in a disposable flexible liner, inserted in the carboy, the flexible liner being such that it is pressed against the internal walls of the carboy at the end of the filling process. During the filling, the internal part of the carboy, which is on the outside of the liner, is preferably maintained at atmospheric pressure.

Description

L'invention est relative à une fontaine de distribution de liquides alimentaires, notamment d'eau, et à des accessoires pour une telle fontaine. Elle concerne de façon générale un réservoir de liquide alimentaire et des accessoires pour un tel réservoir.The invention relates to a dispensing fountain of food liquids, especially water, and accessories for such a fountain. It generally relates to a food liquid reservoir and accessories for such a reservoir.

Les fontaines de distribution d'eau du type à bonbonne sont de plus en plus répandues dans les lieux publics ou privés. De telles fontaines présentent l'avantage de ne pas nécessiter de tuyauterie de distribution et les qualités de l'eau distribuée sont les mêmes que celles de l'eau vendue en bouteille à usage unique.Bottle type water fountains are becoming more common in public and private spaces. Such fountains have the advantage of not requiring distribution piping and the qualities of the distributed water are the same as those of the water sold in a single-use bottle.

Les bonbonnes sont, en général, semi-rigides et de grande capacité. Ainsi pour des raisons de coût elles ne sont pas de type jetable comme les bouteilles d'eau, mais réutilisables, c'est-à-dire remplissables plusieurs fois.The carboys are, in general, semi-rigid and of great capacity. Thus for reasons of cost they are not disposable type like water bottles, but reusable, that is to say, refillable several times.

Chaque bonbonne comporte généralement un bouchon fermé par une pastille de sécurité. Pour installer la bonbonne dans une telle fontaine il faut donc enlever la pastille et faire passer à travers le bouchon un tuyau de distribution d'eau faisant partie de la fontaine.Each bottle usually has a cap closed by a security chip. To install the bottle in such a fountain must remove the pellet and pass through the cap a water distribution pipe part of the fountain.

Lorsque les bonbonnes sont vides elles sont nettoyées puis remplies de nouveau.When the bottles are empty they are cleaned and filled again.

On a constaté que malgré le lavage des bonbonnes, celui ci ne garantissait pas une qualité totale de cette opération et qu'une pollution résiduelle accidentelle restait possible.It was found that despite the washing of the bottles, it did not guarantee a total quality of this operation and that accidental residual pollution remained possible.

Les risques sont d'ailleurs tels que les autorités sanitaires s'en inquiètent.The risks are, moreover, such that the health authorities are worried about it.

L'invention a pour but de garantir une fontaine de distribution d'eau et, de façon plus générale, des conteneurs pour liquides alimentaires tels que des jus de fruits, contre tous risques de pollutions accidentelles.The invention aims to ensure a water dispensing fountain and, more generally, containers for liquid foods such as fruit juice, against all risks of accidental pollution.

Un dispositif connu, décrit dans le document DE-U-87 05 463, est dédié à la collecte de déchets et polluants liquides ou visqueux. Ce dispositif est constitué d'un conteneur rigide à l'intérieur duquel est disposée une poche souple, un canal assurant le passage de l'air entre le conteneur et la poche.A known device, described in DE-U-87 05 463, is dedicated to the collection of liquid and viscous waste and pollutants. This device consists of a rigid container inside which is disposed a flexible bag, a channel ensuring the passage of air between the container and the bag.

Un autre dispositif connu, décrit dans le document FR 2 094 286, permet la conservation de produits sensibles. Ce récipient comporte une enveloppe à paroi extérieure déformable percée d'un trou, et contenant une vessie souple. Le récipient se vidange par pression de la main par un utilisateur, ce dernier devant obturer avec son pouce le trou disposé sur l'enveloppe extérieure.Another known device, described in document FR 2 094 286, allows the preservation of sensitive products. This container has a casing with deformable outer wall pierced with a hole, and containing a flexible bladder. The container is emptied by the pressure of the hand by a user, the latter having to seal with his thumb the hole disposed on the outer casing.

Ces dispositifs ne sont pas spécifiquement adaptés à la distribution d'un liquide alimentaire.These devices are not specifically adapted to the distribution of a food liquid.

L'invention concerne ainsi, selon un premier de ses aspects, un réservoir pour fontaine de distribution de liquide alimentaire qui comprend, d'une part, une bonbonne à paroi sensiblement rigide et, d'autre part, une poche souple, de préférence extensible par remplissage du liquide, et à usage unique, cette poche étant telle qu'elle peut s'appliquer contre les parois internes de la bonbonne lorsque le réservoir est rempli de liquide.The invention thus relates, according to a first of its aspects, to a reservoir for a liquid food dispensing fountain which comprises, on the one hand, a bottle with a substantially rigid wall and, on the other hand, a flexible pouch, preferably extensible by filling the liquid, and disposable, this bag being such that it can be applied against the internal walls of the cylinder when the tank is filled with liquid.

Ainsi le liquide alimentaire à distribuer est contenu dans une poche à usage unique, ce qui offre les mêmes garanties de sécurité alimentaire que pour la distribution en bouteille à usage unique.Thus the food liquid to be dispensed is contained in a single-use bag, which offers the same guarantees of food safety as for single-use bottle dispensing.

En outre la poche étant souple, contrairement à un réservoir rigide, elle ne comprend pas de volume restant disponible pour une entrée d'air quand elle se vide. Ainsi, à la différence des fontaines utilisées actuellement, l'air extérieur ne s'introduit pas dans la poche et n'est pas en contact avec le liquide, ce qui supprime les risques de pollution du liquide restant à distribuer.In addition the bag being flexible, unlike a rigid tank, it does not include a volume remaining available for an air inlet when it empties. Thus, unlike fountains currently used, the outside air does not enter the pocket and is not in contact with the liquid, which eliminates the risk of pollution of the liquid remaining to be dispensed.

La poche souple de la fontaine selon l'invention peut être utilisée avec les bonbonnes classiques, actuellement en service. Dans ces conditions l'invention n'oblige pas à des investissements importants.The flexible pouch of the fountain according to the invention can be used with conventional cylinders, currently in use. Under these conditions the invention does not require significant investments.

La poche souple n'épousant pas rigoureusement les parois internes du conteneur, l'air se trouvant entre la poche et les parois internes du conteneur assure une isolation et garantit une meilleure résistance au gel.The flexible pouch does not closely match the inner walls of the container, the air between the bag and the inner walls of the container provides insulation and guarantees better frost resistance.

Etant donné qu'avec la poche souple de la fontaine selon l'invention il n'y a pratiquement plus de risque de contamination par un défaut de lavage de la bonbonne, les contraintes sanitaires imposées à ce lavage peuvent être relâchées. En outre, il est envisageable de ne plus limiter le nombre d'utilisations de chaque bonbonne comme c'est le cas aujourd'hui. Autrement dit la durée de vie des bonbonnes peut être augmentée ce qui présente, d'une part, un intérêt économique et, d'autre part, limite la quantité de déchets provoquée par la mise au rebut des bonbonnes.Since with the flexible pouch of the fountain according to the invention there is practically no risk of contamination by a lack of washing of the cylinder, the sanitary constraints imposed on this wash can be relaxed. In addition, it is possible to no longer limit the number of uses of each cylinder as is the case today. In other words, the life of the bottles can be increased which has, on the one hand, an economic interest and on the other hand, limits the amount of waste caused by the scrapping of the bottles.

Dans une réalisation préférée la poche est en matériau élastique. Dans ce cas, l'élasticité facilite la distribution du liquide car, quand cette poche est remplie, elle exerce une légère pression sur le liquide.In a preferred embodiment the pocket is of elastic material. In this case, the elasticity facilitates the distribution of the liquid because, when this bag is filled, it exerts a slight pressure on the liquid.

Lorsque la poche souple est en cours de remplissage le volume de l'espace séparant la poche de la paroi interne de la bonbonne diminue. Si de l'air est présent dans ce volume il est nécessaire de l'évacuer pour permettre que la poche vienne contre la paroi de la bonbonne.When the flexible pouch is being filled the volume of the space separating the pocket from the inner wall of the carboy decreases. If air is present in this volume it is necessary to evacuate it to allow the pocket to come against the wall of the cylinder.

A cet effet, selon une réalisation, la bonbonne présente une ouverture ou évent d'évacuation d'air. Cette réalisation présente l'avantage d'empêcher l'utilisation des bonbonnes sans poche de protection.For this purpose, according to one embodiment, the carboy has an opening or vent of air evacuation. This embodiment has the advantage of preventing the use of cylinders without a protective pocket.

Dans une variante l'ouverture de la poche est solidaire d'une bague ou d'un bouchon de fermeture de la bonbonne qui comporte au moins une ouverture d'évacuation d'air.In a variant, the opening of the bag is integral with a ring or a closure cap of the bottle which has at least one air outlet opening.

L'invention concerne ainsi un procédé de remplissage en liquide alimentaire d'une bonbonne destinée à être installée dans une fontaine de distribution d'un tel liquide, dans lequel le liquide est introduit dans une poche souple, à usage unique, introduite dans la bonbonne, la poche souple étant telle qu'à la fin du remplissage elle s'applique contre les parois internes de la bonbonne.The invention thus relates to a food liquid filling process of a bottle intended to be installed in a dispensing fountain of such a liquid, in which the liquid is introduced into a flexible pouch, for single use, introduced into the bottle. , the flexible pouch being such that at the end of filling it is applied against the inner walls of the cylinder.

De préférence, lors du remplissage, la partie interne de la bonbonne qui se trouve à l'extérieur de la poche est maintenue à pression atmosphérique.Preferably, during filling, the inner part of the carboy which is outside the bag is maintained at atmospheric pressure.

L'invention concerne aussi un procédé de distribution de liquide alimentaire à l'aide d'une bonbonne remplie conformément au procédé défini ci-dessus, dans lequel, lors de la distribution, la partie interne de la bonbonne qui se trouve à l'extérieur de la poche est maintenue à une pression atmosphérique ou à une pression supérieure.The invention also relates to a method of dispensing liquid food using a cylinder filled according to the method defined above, in which, during distribution, the inner part of the cylinder which is outside of the bag is maintained at atmospheric pressure or at a higher pressure.

L'invention se rapporte aussi à une poche à usage unique pour l'application du procédé de remplissage défini ci-dessus.The invention also relates to a disposable bag for the application of the filling method defined above.

Cette poche est, par exemple, en matériau élastique, son volume initial, avant remplissage, étant sensiblement inférieur au volume intérieur de la bonbonne.This pocket is, for example, an elastic material, its initial volume, before filling, being substantially less than the internal volume of the cylinder.

La poche comprend, dans une réalisation, un rebord destiné à chevaucher le goulot de la bonbonne.The pocket comprises, in one embodiment, a flange for overlapping the neck of the bottle.

L'invention concerne également un ensemble à poche et bouchon de bonbonne dans lequel l'ouverture de la poche est solidaire du bouchon, le diamètre de l'ouverture de la poche étant inférieur au diamètre intérieur de goulot de la bonbonne et le bouchon présentant au moins un trou pour mettre en communication avec l'atmosphère l'espace intérieur de la bonbonne qui est extérieur à la poche.The invention also relates to a bag and bottle cap assembly in which the opening of the bag is integral with the cap, the diameter of the opening of the bag being smaller than the internal diameter of the neck of the bottle and the plug having the less a hole to port with the atmosphere the interior space of the carboy that is outside the pocket.

Selon une réalisation, cet ensemble est tel que le bouchon présente une ouverture centrale pour l'introduction et l'évacuation de liquide, et cette ouverture centrale est bordée par une paroi intérieure cylindrique dont est solidaire l'ouverture de la poche.According to one embodiment, this assembly is such that the plug has a central opening for the introduction and discharge of liquid, and this central opening is bordered by a cylindrical inner wall which is secured to the opening of the pocket.

Le bouchon peut comporter, en outre, pour boucher son ouverture centrale, un bouchon central coopérant par encliquetage avec la paroi intérieure cylindrique. Selon une réalisation, le bouchon central présente une partie cylindrique centrale fermée par un bouchon intérieur d'extrémité qui est séparable du bouchon central lors de l'installation de la bonbonne dans une fontaine de distribution de liquide.The cap may further comprise, to plug its central opening, a central plug cooperating by snapping with the cylindrical inner wall. According to one embodiment, the central plug has a cylindrical portion central closed by an inner end cap which is separable from the central plug during the installation of the bottle in a liquid dispensing fountain.

L'invention se rapporte également à un ensemble à poche et bague solidaire de l'ouverture de la poche, cette bague présentant au moins un canal pour mettre en communication avec l'atmosphère l'espace intérieur de la bonbonne qui est extérieur à la poche.The invention also relates to a pocket and ring assembly integral with the opening of the pocket, this ring having at least one channel for communicating with the atmosphere the interior space of the carboy which is outside the pocket .

L'invention concerne aussi une bonbonne pour l'application du procédé de remplissage défini ci-dessus qui comprend au moins un trou pour mettre en relation l'atmosphère extérieur et l'espace intérieur de la bonbonne qui est extérieur à la poche.The invention also relates to a bottle for the application of the filling method defined above which comprises at least one hole for connecting the external atmosphere and the internal space of the bottle which is outside the bag.

L'invention concerne aussi un accessoire pour fontaine de distribution de liquide alimentaire qui est caractérisé en ce qu'il comporte une poche souple, à usage unique, remplie du liquide à distribuer et destinée à être introduite dans la fontaine pour cette distribution, la poche souple étant telle qu'au fur et à mesure qu'elle se vide du liquide, sa paroi reste en contact avec la surface libre de ce liquide afin qu'il ne subsiste pratiquement pas d'espace vide à l'intérieur de la poche, partiellement vidée de liquide.The invention also relates to an accessory for drinking fountain dispensing liquid which is characterized in that it comprises a flexible pouch, disposable, filled with the liquid to be dispensed and intended to be introduced into the fountain for this distribution, the pocket flexible being such that as it empties the liquid, its wall remains in contact with the free surface of the liquid so that there is virtually no empty space inside the pocket, partially emptied of liquid.

Le matériau de la paroi de la poche souple est de préférence élastique.The material of the wall of the flexible bag is preferably elastic.

Dans une réalisation, la poche comprend un rebord destiné à chevaucher un goulot de bonbonne.In one embodiment, the pouch includes a flange for overlapping a bottle neck.

La poche peut être solidaire d'un bouchon de bonbonne. Dans ce cas, le bouchon de bonbonne présente, par exemple, une ouverture centrale pour l'introduction et l'évacuation de liquide, cette ouverture étant bordée par une paroi intérieure cylindrique dont est solidaire l'ouverture de la poche. Dans une réalisation, l'extrémité de la paroi intérieure cylindrique présente un rebord dont est solidaire l'ouverture de la poche. Le bord d'ouverture de la poche est, par exemple, surmoulé au rebord d'extrémité de la paroi intérieure cylindrique du bouchon. Le bouchon de bonbonne peut comporter, en outre, pour boucher son ouverture centrale, un bouchon central coopérant par encliquetage avec la paroi intérieure cylindrique. Le bord d'ouverture de la poche coopère, dans une réalisation, avec le rebord d'extrémité de la paroi intérieure cylindrique en forme de gouttière et est maintenu contre ce rebord quand le bouchon central est mis en place. Dans ce dernier cas, on peut prévoir une bague interposée entre le bord d'extrémité de la poche et une arête d'extrémité d'un manchon du bouchon central.The pocket can be secured to a bottle cap. In this case, the cylinder cap has, for example, a central opening for the introduction and discharge of liquid, this opening being bordered by a cylindrical inner wall which is secured to the opening of the pocket. In one embodiment, the end of the cylindrical inner wall has a rim which is secured to the opening of the pocket. The opening edge of the pocket is, for example, overmolded at the end rim of the cylindrical inner wall of the plug. The bottle cap may further comprise, to plug its central opening, a central plug cooperating by snapping with the cylindrical inner wall. The opening edge of the pocket cooperates, in one embodiment, with the end flange of the gutter-shaped cylindrical inner wall and is held against this flange when the central plug is put in place. In the latter case, it is possible to provide a ring interposed between the end edge of the pocket and an end edge of a sleeve of the central plug.

Le bouchon central présente, dans un mode de réalisation, une partie cylindrique centrale fermée par un bouchon intérieur d'extrémité qui est séparable du bouchon central lors de l'installation d'une bonbonne dans une fontaine de distribution de liquide.The central plug has, in one embodiment, a central cylindrical portion closed by an inner end cap which is separable from the central plug during the installation of a cylinder in a liquid dispensing fountain.

Le bouchon central présente, selon une réalisation, une partie cylindrique centrale fermée par un élément à prédécoupes, ces prédécoupes permettant le passage d'un tube lors de l'installation d'une bonbonne dans une fontaine de distribution de liquide.The central plug has, in one embodiment, a central cylindrical portion closed by a pre-cut element, these pre-cuts allowing the passage of a tube during the installation of a cylinder in a liquid dispensing fountain.

Les prédécoupes ont, par exemple, des directions radiales ou une forme de spirale.Pre-cuts have, for example, radial directions or a spiral shape.

L'accessoire peut comprendre une bague solidaire de l'ouverture de la poche, cette bague présentant au moins un canal pour mettre en communication avec l'atmosphère l'espace intérieur d'une bonbonne qui est extérieur à la poche.The accessory may comprise a ring integral with the opening of the pocket, this ring having at least one channel for communicating with the atmosphere the interior space of a cylinder which is outside the pocket.

Dans le mode de réalisation de l'invention qui est représenté sur les figures 1 et 2, pour la distribution d'eau dans une fontaine autonome, c'est-à-dire non connectée à une canalisation d'un réseau de distribution, on prévoit une bonbonne 10 en matière plastique sensiblement rigide, par exemple transparente et, pour garantir la propreté de l'eau distribuée, celle-ci est contenue dans une poche 12 en matériau élastomère qui, avant remplissage (figure 1), présente un volume sensiblement inférieur à celui de la bonbonne 10.In the embodiment of the invention which is shown in FIGS. 1 and 2, for the distribution of water in an autonomous fountain, that is to say not connected to a pipe of a distribution network, one provides a cylinder 10 of substantially rigid plastic, for example transparent and, to ensure the cleanliness of the dispensed water, it is contained in a bag 12 of elastomeric material which, before filling (Figure 1), has a volume substantially less than that of the cylinder 10.

Par exemple comme on peut le voir sur la figure 1, avant remplissage, la longueur de la poche 12 est environ égale à la moitié de la hauteur de la bonbonne 10 et son diamètre est sensiblement plus faible que celui du goulot 14 de la bonbonne (figure 2). De façon générale, le diamètre et la longueur de la poche extensible ou élastique seront déterminés par la viscosité du liquide alimentaire.For example, as can be seen in FIG. 1, before filling, the length of the bag 12 is approximately equal to half the height of the bottle 10 and its diameter is substantially smaller than that of the neck 14 of the bottle ( Figure 2). In general, the diameter and the length of the extensible or elastic bag will be determined by the viscosity of the liquid food.

Après remplissage en eau la poche 12 épouse la paroi interne de la bonbonne.After filling the bag with water 12 marries the inner wall of the bottle.

Dans cet exemple la poche 12 présente une ouverture bordée par un rebord 16 chevauchant le goulot 14 (figures 1 et 3) .In this example the pocket 12 has an opening bordered by a flange 16 overlapping the neck 14 (Figures 1 and 3).

Pour permettre l'application de la poche 12 contre la paroi interne de la bonbonne 10 (figure 2) il est nécessaire qu'au cours du remplissage en eau de la poche 12 l'air se trouvant dans la bonbonne 10 puisse être évacué. A cet effet, dans cette réalisation, la bonbonne 10 comporte au moins un trou (non montré) en un emplacement quelconque.To allow the application of the bag 12 against the inner wall of the cylinder 10 (Figure 2) it is necessary that during the water filling of the bag 12 the air in the cylinder 10 can be evacuated. For this purpose, in this embodiment, the cylinder 10 has at least one hole (not shown) at any location.

Après remplissage la bonbonne est fermée par un bouchon 20 (figure 3) de type connu.After filling the bottle is closed by a plug 20 (Figure 3) of known type.

Ce bouchon 20 connu comporte une jupe 22 retenue par encliquetage par la partie supérieure 24 du goulot dont la paroi externe est recouverte par le rebord 16 de la poche 12.This known stopper 20 comprises a skirt 22 held snap-fitting by the upper part 24 of the neck whose outer wall is covered by the rim 16 of the pocket 12.

Le bouchon 20 comporte une ouverture centrale 26 bordée par une partie cylindrique 28 plongeant à l'intérieur de la bonbonne et l'extrémité intérieure de cette partie cylindrique 28 est fermée par un bouchon intérieur 30 qui comporte lui-même deux rebords 32 et 34. Le rebord 32 vient s'appliquer contre la paroi interne de la paroi cylindrique 28 tandis que le rebord 34 s'applique contre la paroi externe de la paroi cylindrique 28. Le bouchon intérieur 30 est maintenu à l'extrémité de la paroi 28 grâce à un encliquetage du rebord 34 sur un bourrelet externe 36 de cette paroi 28.The plug 20 has a central opening 26 bordered by a cylindrical portion 28 immersed inside the cylinder and the inner end of this cylindrical portion 28 is closed by an inner plug 30 which itself comprises two flanges 32 and 34. The flange 32 is pressed against the inner wall of the cylindrical wall 28 while the flange 34 is applied against the outer wall of the cylindrical wall 28. The inner cap 30 is held at the end of the wall 28 by means of a snap of the flange 34 on an outer bead 36 of this wall 28.

L'ouverture centrale 26 est fermée par une pastille 40. La colle appliquant la pastille 40 contre la paroi externe du bouchon 20 est telle que lorsque la pastille 40 est décollée elle ne peut plus être recollée. Ainsi, une bonbonne dépourvue de pastille 40 ne doit pas être utilisée car elle ne comporte pas la pastille constituant une garantie contre un accès non autorisé à l'intérieur de la bonbonne.The central opening 26 is closed by a pellet 40. The adhesive applying the pellet 40 against the outer wall of the plug 20 is such that when the pellet 40 is peeled off it can not be glued again. Thus, a carboy devoid of pellet 40 should not be used because it does not include the pellet constituting a guarantee against unauthorized access to the interior of the bottle.

De façon également en soi connue l'ouverture 26, la paroi 28 et le bouchon 30 sont destinés à coopérer avec un tube de distribution 42 de la fontaine. Ainsi, quand la bonbonne est installée dans la fontaine le goulot est tourné vers le bas (c'est-à-dire dans le sens contraire de celui montré sur les figures 1, 2 et 3) et on fait pénétrer le tube de distribution 42 dans l'ouverture 26. L'extrémité de ce tube 42 qui pénètre dans la bonbonne est fermée. Elle repousse le bouchon intérieur 30 qui reste, en principe, encliqueté à l'extrémité du tuyau 42 comme représenté en traits interrompus sur la figure 3. Ce conduit 42 présente, à l'intérieur de la bonbonne, des ouvertures 44 par lesquelles l'eau de la bonbonne peut s'évacuer. Le conduit 42 est relié à un robinet (non montré) extérieur.Also in known manner the opening 26, the wall 28 and the cap 30 are intended to cooperate with a dispensing tube 42 of the fountain. So when the bottle is installed in the fountain the neck is turned down (That is to say in the opposite direction to that shown in Figures 1, 2 and 3) and is introduced into the delivery tube 42 in the opening 26. The end of this tube 42 which enters the bottle is closed. It pushes the inner plug 30 which remains, in principle, latched to the end of the pipe 42 as shown in phantom in Figure 3. This conduit 42 has, inside the carboy, openings 44 through which the water from the bottle can drain. The conduit 42 is connected to a tap (not shown) outside.

Lorsque la bonbonne est extraite de la fontaine, le bouchon 30 vient en principe reprendre sa place à l'extrémité de la paroi cylindrique 28, ce qui garantit l'étanchéité de la bonbonne après sa séparation de la fontaine.When the bottle is removed from the fountain, the cap 30 is in principle resume its place at the end of the cylindrical wall 28, which ensures the tightness of the bottle after its separation from the fountain.

Ensuite la bonbonne est envoyée à un centre de nettoyage et de remplissage. Dans ce centre le bouchon 20 et la poche 12 sont jetés, la bonbonne est nettoyée et on installe une nouvelle poche 12 et un nouveau bouchon avant ou après remplissage selon la variante utilisée, ce qui garantit la propreté du réservoir.Then the bottle is sent to a cleaning and filling center. In this center the cap 20 and the bag 12 are discarded, the bottle is cleaned and a new bag 12 and a new plug is installed before or after filling according to the variant used, which guarantees the cleanliness of the tank.

Ainsi, la fontaine équipée d'une bonbonne à poche 12 présente les mêmes garanties d'hygiène que l'eau distribuée dans des bouteilles à usage unique.Thus, the fountain equipped with a pocket cylinder 12 has the same hygiene guarantees as the water dispensed in single-use bottles.

Les figures 4 et 4a représentent une fontaine 50 équipée d'une bonbonne 10 et d'une poche intérieure 12 conforme à l'invention. Sur la figure 4 on voit que la poche est pleine alors que sur la figure 4a l'eau ne remplit plus qu'environ le quart du volume de la bonbonne 10. Lors de la distribution d'eau, la poche étant souple, il ne se produit pas de remontée d'air extérieur à travers le liquide car la poche tend à reprendre son faible volume initial. Ainsi, l'eau n'entre pas en contact avec l'air extérieur, ce qui constitue une garantie supplémentaire de la qualité du liquide embouteillé.Figures 4 and 4a show a fountain 50 equipped with a cylinder 10 and an inner bag 12 according to the invention. In FIG. 4, it can be seen that the bag is full whereas in FIG. 4a the water only fills about a quarter of the volume of the bottle 10. When dispensing water, the bag being flexible, it does not there is no rise of outside air through the liquid because the pocket tends to resume its low initial volume. Thus, the water does not come into contact with the outside air, which is an additional guarantee of the quality of the bottled liquid.

L'eau contenue dans la poche 12 est distribuée uniquement par gravité. Cependant, dans le cas où la poche 12 est en matériau élastique, l'élasticité exerce une légère pression qui améliore la régularité de la distribution de l'eau.The water contained in the pocket 12 is distributed solely by gravity. However, in the case where the pocket 12 is made of elastic material, the elasticity exerts a slight pressure which improves the regularity of the distribution of the water.

Ainsi, on constate, qu'avec l'invention, on peut continuer à utiliser les bonbonnes et les bouchons classiques et qu'il n'est pas nécessaire de modifier les fontaines de distribution d'eau, tout en diminuant de façon importante les risques de contamination de l'eau. En effet, lors du remplissage, des résidus pouvant rester dans la bonbonne après lavage n'auront pas d'effet contaminant et l'air environnant la fontaine de distribution d'eau ne traverse pas l'eau distribuée.Thus, it can be seen that, with the invention, it is still possible to use conventional bottles and plugs and that it is not necessary to modify the water dispensing fountains while significantly reducing the risks. of water contamination. Indeed, during the filling, residues that can remain in the cylinder after washing will have no contaminating effect and the air surrounding the water dispensing fountain does not cross the distributed water.

La présence de la poche 12 limite également les risques pour la cuve de distribution d'eau en cours de remplissage. En effet, avec le procédé classique de remplissage on prévoit de reverser dans la cuve de distribution les trop pleins d'eau revenant des bonbonnes remplies. Ainsi, avec le système actuel, une bonbonne contaminée peut contaminer l'ensemble de la cuve de distribution, ce qui ne peut être le cas avec l'utilisation d'une poche à usage unique.The presence of the pocket 12 also limits the risks for the water dispensing tank being filled. Indeed, with the conventional method of filling is expected to return to the dispensing tank too full of water returning filled carboys. Thus, with the current system, a contaminated tank can contaminate the entire dispensing tank, which can not be the case with the use of a disposable pocket.

Dans le mode de réalisation de l'invention décrit ci-dessus les seules modifications apportées aux fontaines classiques sont, d'une part, un perçage de la bonbonne en fonction de la variante retenue et, d'autre part, des poches souples de faible prix.In the embodiment of the invention described above, the only modifications made to the conventional fountains are, on the one hand, a piercing of the carboy according to the variant chosen and, on the other hand, weak flexible pockets. price.

Dans le mode de réalisation de l'invention qui est représenté sur la figure 5 la poche 60 est solidaire d'un bouchon 62 destiné à fermer la bonbonne (non montrée sur la figure 5).In the embodiment of the invention shown in FIG. 5, the bag 60 is secured to a stopper 62 intended to close the bottle (not shown in FIG. 5).

Ce bouchon 62 comporte ainsi une paroi supérieure 64 avec une ouverture centrale 66, bordée par une paroi cylindrique 68 en saillie vers l'intérieur de la poche 60. Le bouchon comprend également un rebord extérieur 70 analogue au rebord 22 dans le mode de réalisation représenté sur la figure 3, c'est-à-dire destiné à s'encliqueter sur le haut du goulot de la bonbonne.This plug 62 thus comprises an upper wall 64 with a central opening 66, bordered by a cylindrical wall 68 projecting towards the inside of the pocket 60. The stopper also comprises an outer rim 70 similar to the rim 22 in the embodiment shown in Figure 3, that is to say intended to snap on the top of the neck of the bottle.

Les bords de l'ouverture de la poche 60 sont solidaires, par exemple par collage ou thermocollage, de la face intérieure de la paroi 64, entre la paroi cylindrique 68 et le rebord extérieur 70.The edges of the opening of the pocket 60 are integral, for example by gluing or heat-sealing, of the inner face of the wall 64, between the cylindrical wall 68 and the outer rim 70.

Un bouchon central 72 est destiné à fermer l'ouverture centrale 66 après remplissage de la poche 60, le bouchon 62 étant installé sur le goulot de la bonbonne.A central plug 72 is intended to close the central opening 66 after filling the bag 60, the plug 62 being installed on the neck of the bottle.

La paroi supérieure 64 comporte au moins un trou 74 d'évacuation d'air qui se trouve entre sa périphérie extérieure et la poche 60. Ce trou 74 permet d'évacuer l'air se trouvant entre la poche 60 et la paroi interne de la bonbonne quand on remplit la poche 60. Ce trou 74 permet aussi de faire rentrer de l'air dans la bonbonne à l'extérieur de la poche 60, quand cette dernière se vide en cours d'utilisation, c'est-à-dire lorsqu'elle est installée sur la fontaine.The upper wall 64 has at least one air discharge hole 74 which is located between its outer periphery and the pocket 60. This hole 74 serves to evacuate the air between the pocket 60 and the inner wall of the when filling the pocket 60. This hole 74 also allows air to enter the bottle outside the pocket 60, when the latter becomes empty during use, that is to say when installed on the fountain.

La figure 6 correspond à une variante de réalisation de la figure 5. Dans cet exemple l'arête supérieure de la poche 60 est solidaire de la paroi cylindrique interne 68. Le bouchon central 72 présente un bord cylindrique externe 76 destiné à coopérer par encliquetage avec la paroi cylindrique interne 68. Dans cet exemple le bord 76 du bouchon central 72 présente une rainure 80 destinée à coopérer avec une nervure 82 de la face interne de la paroi 68.FIG. 6 corresponds to an alternative embodiment of FIG. 5. In this example, the upper edge of the pocket 60 is integral with the internal cylindrical wall 68. The central plug 72 has an outer cylindrical edge 76 intended to cooperate by snapping with the inner cylindrical wall 68. In this example the edge 76 of the central plug 72 has a groove 80 intended to cooperate with a rib 82 of the inner face of the wall 68.

Le bouchon central 72 comporte une ouverture centrale 84 bordée par une partie cylindrique interne 86 destinée à laisser le passage du tube de distribution d'eau de la fontaine (comme décrit en relation avec la figure 3). Le conduit 86 est fermé par un bouchon interne 88 analogue au bouchon 30 représenté sur la figure 3 et ayant le même rôle que ce bouchon 30.The central plug 72 has a central opening 84 bordered by an internal cylindrical portion 86 intended to allow the passage of the water dispensing tube of the fountain (as described in connection with Figure 3). The conduit 86 is closed by an inner plug 88 similar to the plug 30 shown in FIG. 3 and having the same function as this plug 30.

Ce bouchon 88, comme le bouchon 30, est désolidarisé du conduit cylindrique 86 quand la bonbonne est installée dans la fontaine et revient fermer ce conduit quand la bonbonne est retirée de la fontaine. Il peut cependant arriver qu'au cours de l'opération d'extraction de la bonbonne de la fontaine, le bouchon intérieur 88 (tout comme le bouchon interne 30 de la figure 3) ne revienne pas boucher le conduit 86 et reste dans la poche 60 à jeter. Mais ce défaut de fonctionnement ne constitue pas un inconvénient puisque la poche 60 doit être jetée.This cap 88, like the cap 30, is disengaged from the cylindrical duct 86 when the bottle is installed in the fountain and returns close this duct when the bottle is removed from the fountain. However, it may happen that during the extraction operation of the fountain bottle, the inner cap 88 (just like the inner cap 30 of Figure 3) does not clog the conduit 86 and remains in the pocket 60 to throw. But this malfunction is not a disadvantage since the pocket 60 must be discarded.

On va maintenant décrire en relation avec les figures 7 et 8 un mode de réalisation de l'invention qui permet d'utiliser un bouchon de bonbonne du type classique, c'est-à-dire un bouchon analogue au bouchon 20 décrit en relation avec la figure 3, sans cependant avoir à percer la bonbonne pour permettre l'évacuation d'air lors du remplissage ainsi que l'introduction d'air lors de la distribution d'eau.An embodiment of the invention will now be described with reference to FIGS. 7 and 8, which makes it possible to use a bottle cap of the conventional type, that is to say a plug similar to the stopper 20 described in connection with FIG. Figure 3, without however having to drill the cylinder to allow the evacuation of air during the filling and the introduction of air during the distribution of water.

A cet effet, l'ouverture de la poche 90 (figure 7) est solidaire d'une bague 92 dont la face inférieure est destinée à s'appuyer sur l'arête supérieure 94 de la bonbonne 96 et cette face inférieure de la bague 92 présente au moins une rainure 98 qui débouche, d'un côté, à l'intérieur 100 de la bonbonne, entre la poche 90 et la paroi interne de cette bonbonne, et, de l'autre côté, à l'extérieur de la bonbonne.For this purpose, the opening of the pocket 90 (FIG. 7) is integral with a ring 92 whose lower face is intended to bear on the upper edge 94 of the bottle 96 and this lower face of the ring 92. has at least one groove 98 which opens, on one side, inside 100 of the carboy, between the pocket 90 and the inner wall of this carboy, and on the other side, outside the carboy .

Dans l'exemple on prévoit une pluralité de telles rainures 981, 982, etc. (figure 8).In the example there is provided a plurality of such grooves 98 1 , 98 2 , etc. (Figure 8).

Le bouchon de fermeture n'est pas installé lors du remplissage en eau de la poche 90. Par contre, comme décrit en relation avec la figure 3, lors de la distribution d'eau le bouchon (non montré sur la figure 7) est installé. Ce bouchon s'oppose partiellement à l'entrée d'air dans l'espace entre la poche 90 et la bonbonne. Toutefois le bouchon n'assure pas une étanchéité complète à l'air et permet donc l'introduction d'air dans l'espace entre la poche 90 et la bonbonne 96. Ce débit d'air est cependant moins important que lors du remplissage. Mais cette différence entre les débits ne constitue pas un inconvénient car la distribution d'eau s'effectue beaucoup plus lentement que le remplissage en eau.The closure cap is not installed during the water filling of the pocket 90. On the other hand, as described in connection with FIG. 3, during the water distribution the plug (not shown in FIG. 7) is installed . This plug partially opposes the entry of air into the space between the pocket 90 and the bottle. However, the cap does not provide complete airtightness and therefore allows the introduction of air into the space between the bag 90 and the cylinder 96. This air flow is however less important than during the filling. But this difference between flow rates is not a disadvantage because the distribution of water is much slower than filling water.

Pour diminuer le nombre ou la section des canaux 98, le remplissage en eau de la poche 90 peut s'effectuer en éloignant la bague 92 de l'arête 94 de la bonbonne 96. Dans ces conditions, l'air se trouvant dans la bonbonne à l'extérieur de la poche 90 peut, lors du remplissage, s'échapper par l'espace ménagé entre l'arête 94 et la bague 92.To reduce the number or the section of the channels 98, the water filling of the pocket 90 can be carried out by moving the ring 92 away from the edge 94 of the cylinder 96. In these conditions, the air in the cylinder outside the pocket 90 can, during filling, escape through the space between the edge 94 and the ring 92.

Quel que soit le mode de réalisation, dans une variante, pour faciliter la distribution d'eau dans la fontaine, on applique dans la bonbonne une surpression autour de la poche.Whatever the embodiment, in a variant, to facilitate the dispensing of water into the fountain, there is applied in the bottle an overpressure around the pocket.

Dans le mode de réalisation de l'invention qui est représenté sur les figures 9, 10 et 11, le bouchon 110 comporte vers l'intérieur un manchon 112, par exemple analogue au manchon 68 de la réalisation représentée sur la figure 6, présentant à son extrémité inférieure une gouttière 114 de laquelle est solidaire par surmoulage la poche 116 (figure 11).In the embodiment of the invention which is shown in FIGS. 9, 10 and 11, the plug 110 has inwardly a sleeve 112, for example similar to the sleeve 68 of the embodiment shown in FIG. its lower end a gutter 114 which is secured by overmoulding the pocket 116 (Figure 11).

À cet effet, le bouchon est, par exemple, réalisé en polyéthylène ou polypropylène avec une gouttière 114 dont le fond présente des trous 1181, 1182 régulièrement espacés et dont le rebord comporte des lumières 1201, etc. également régulièrement espacées.For this purpose, the cap is, for example, made of polyethylene or polypropylene with a gutter 114 whose bottom has holes 118 1 , 118 2 regularly spaced and whose rim comprises lights 120 1 , etc. also regularly spaced.

Ensuite, cette gouttière est plongée dans un bain de latex fondu pour réaliser la poche 116 soudée et surmoulée à la gouttière comme représenté sur la figure 11.Then, this channel is immersed in a bath of molten latex to make the pocket 116 welded and overmolded to the gutter as shown in Figure 11.

Dans ce cas, c'est l'ensemble du bouchon et de la poche qui est jetable.In this case, it is the entire plug and the pocket that is disposable.

Dans l'exemple représenté sur les figures 12, 13 et 14, le bouchon 122 comporte une partie périphérique 122 et une partie centrale 134. La partie périphérique comprend un manchon 124 avec à son extrémité une gorge 126 recevant le bord roulé 128 de la poche 130.In the example shown in FIGS. 12, 13 and 14, the plug 122 comprises a peripheral portion 122 and a central portion 134. The peripheral portion comprises a sleeve 124 with at its end a groove 126 receiving the rolled edge 128 of the pocket 130.

Le bord roulé 128 est maintenu au fond de la gorge 126 grâce à une bague 132 coopérant avec la partie centrale 134 qui présente un manchon extérieur 138 dont les arêtes d'extrémité 140 viennent appuyer la bague 132 contre le bord roulé 128 afin de l'appliquer au fond de la gorge 126 lorsque la partie centrale 134 du bouchon est associée à la partie périphérique 122 par coopération d'une saillie 144 du manchon 138 dans une rainure 146 du manchon central de la partie périphérique 122 du bouchon.The rolled edge 128 is held at the bottom of the groove 126 through a ring 132 cooperating with the central portion 134 which has an outer sleeve 138 whose end edges 140 support the ring 132 against the rolled edge 128 to the apply to the bottom of the groove 126 when the central portion 134 of the plug is associated with the peripheral portion 122 by cooperation of a projection 144 of the sleeve 138 in a groove 146 of the central sleeve of the peripheral portion 122 of the plug.

Dans cette réalisation, le diamètre de la partie d'extrémité du manchon 124 est supérieur au diamètre du reste du manchon de façon à réaliser un rebord 150 constituant une butée supérieure pour la bague 132.In this embodiment, the diameter of the end portion of the sleeve 124 is greater than the diameter of the remainder of the sleeve so as to provide a flange 150 constituting an upper stop for the ring 132.

Dans la réalisation montrée sur la figure 12, la partie centrale 134 du bouchon comporte un manchon central 152 analogue au manchon 86 de l'exemple de la figure 6 qui se termine à son extrémité inférieure par une partie tronconique 154 ayant un rôle analogue à l'élément 88 de la figure 6, à savoir qu'il empêche, ou limite, des fuites de liquide quand on extrait la bonbonne de la fontaine.In the embodiment shown in FIG. 12, the central portion 134 of the cap comprises a central sleeve 152 similar to the sleeve 86 of the example of FIG. 6, which ends at its lower end with a frustoconical portion 154 having a role similar to that of FIG. element 88 of Figure 6, namely that it prevents, or limits, leakage of liquid when the cylinder is extracted from the fountain.

Dans ces deux exemples, cet élément 154 présente des découpes, ou prédécoupes, pour permettre que le tube 42 (figure 3) puisse pénétrer à l'intérieur de la bonbonne. Dans la réalisation montrée sur la figure 13, les prédécoupes ont une forme radiale, c'est-à-dire que les découpes 156 convergent au centre 158, selon l'axe 160 du bouchon.In these two examples, this element 154 has cutouts, or pre-cuts, to allow the tube 42 (Figure 3) to penetrate inside the bottle. In the embodiment shown in FIG. 13, the precuts have a radial shape, that is to say that the cuts 156 converge at the center 158, along the axis 160 of the plug.

Dans l'exemple montré sur la figure 14, l'élément 154 est découpé en spirale 160.In the example shown in FIG. 14, the element 154 is cut into a spiral 160.

L'exemple représenté sur la figure 15 se distingue de celui représenté sur la figure 12 par le fait que la partie centrale cylindrique du bouchon principal 170 présente une partie supérieure 172 de plus grand diamètre dans laquelle pénètre par cliquetage 176 le bouchon central 174 et cette partie supérieure 172 est prolongée vers le bas par une autre paroi cylindrique 178 de plus faible diamètre raccordée par un épaulement 180 à la partie supérieure 172. Cet épaulement 180 constitue un appui pour l'extrémité inférieure 182 du bouchon central 174.The example shown in FIG. 15 differs from that shown in FIG. 12 in that the central cylindrical portion of the main plug 170 has an upper portion 172 of larger diameter in which ratchet 176 engages the central plug 174 and this upper part 172 is extended downwards by another cylindrical wall 178 of smaller diameter connected by a shoulder 180 to the upper part 172. This shoulder 180 constitutes a support for the lower end 182 of the central plug 174.

La paroi cylindrique 178 se termine par un rebord 184, tourné vers l'intérieur, auquel est soudée la poche 190.The cylindrical wall 178 terminates in a flange 184, turned inwards, to which the pocket 190 is welded.

Le mode de réalisation de l'invention qui est représenté sur la figure 16 se distingue de celui représenté sur la figure 15 par le fait que la paroi 178 ne présente pas de rebord inférieur. La poche 192 est soudée à la partie inférieure 194 de cette paroi 178.The embodiment of the invention shown in FIG. 16 differs from that shown in FIG. Figure 15 in that the wall 178 does not have a lower rim. The pocket 192 is welded to the lower portion 194 of this wall 178.

Dans ces modes de réalisation, le matériau de la poche est soit souple et expansible, soit souple et non-expansible.In these embodiments, the pouch material is either flexible and expandable, or flexible and non-expandable.

De façon générale, dans toutes les réalisations, c'est le caractère souple de la poche qui empêche que, lors de la distribution de liquide, de l'air puisse pénétrer dans le liquide car la partie supérieure de la poche qui se vide s'affaisse par gravité et ne laisse pratiquement pas de place pour un retour d'air. Autrement dit, la partie supérieure se replie et reste pratiquement en contact avec la surface libre du liquide restant. Dans le cas d'une poche élastique, les plis sont moins nombreux.In general, in all the embodiments, it is the flexible nature of the pouch which prevents that, during the distribution of liquid, air can penetrate into the liquid because the upper part of the empty bag is empty. gravity collapses and leaves virtually no room for air return. In other words, the upper part folds and remains substantially in contact with the free surface of the remaining liquid. In the case of an elastic pocket, the folds are fewer.
