Description

ACCESSOIRES POUR CONTENEURS DE LIQUIDES ALIMENTAIRES, ACCESSORIES FOR CONTAINERS OF FOOD LIQUIDS,
NOTAMMENT D'EAUESPECIALLY WATER
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 fountain for dispensing food liquids, in particular water, and to accessories for such a fountain. It generally relates to a reservoir for food liquid 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 1 ' avantage de ne pas nécessiter de tuyauterie de distribution et les qualités de 1 ' eau distribuée sont les mêmes que celles de l'eau vendue en bouteille à usage unique.Water dispenser fountains of the bottle type are more and more widespread in public and private places. Such fountains have the advantage of not requiring distribution piping and the qualities of the water distributed are the same as those of 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 cylinders are, in general, semi-rigid and of large capacity. Thus for cost reasons they are not of the 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. Lorsque les bonbonnes sont vides elles sont nettoyées puis remplies de nouveau.Each bottle generally has a cap closed by a security disc. To install the cylinder in such a fountain, it is therefore necessary to remove the tablet and pass a water distribution pipe that forms part of the fountain through the plug. When the cylinders are empty they are cleaned and then refilled.
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 cylinders, this did not guarantee a total quality of this operation and that an accidental residual pollution remained possible.
Les risques sont d'ailleurs tels que les autorités sanitaires s ' en inquiètent .The risks are also such that the health authorities are concerned.
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 object of the invention is to guarantee a water distribution fountain and, more generally, containers for food liquids such as fruit juices, against any risk of accidental pollution.
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, a reservoir for a fountain for dispensing liquid food which comprises, on the one hand, a cylinder with a substantially rigid wall and, on the other hand, a flexible pocket, preferably expandable by filling with liquid, and for single use, this pocket 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. 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.Thus, the liquid food to be dispensed is contained in a single-use bag, which offers the same guarantees of food safety as for distribution in a single-use bottle. In addition, the bag being flexible, unlike a rigid tank, it does not include any volume remaining available for an air inlet when it empties. Thus, unlike the fountains currently used, 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 1 ' invention peut être utilisée avec les bonbonnes classiques, actuellement en service. Dans ces conditions l'invention n'oblige pas à des investissements importants. 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. 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. 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.The flexible pocket of the fountain according to the invention can be used with conventional bottles, currently in use. Under these conditions, the invention does not require significant investment. Since the flexible pouch does not strictly conform to the internal walls of the container, the air between the pocket and the internal walls of the container provides insulation and guarantees better frost resistance. Given that with the flexible pocket of the fountain according to the invention there is practically no longer any risk of contamination by a defect in washing the cylinder, the health constraints imposed on this washing 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 cylinders can be increased, which presents, on the one hand, an economic advantage and, on the other hand, limits the amount of waste caused by the scrapping of the cylinders. In a preferred embodiment, the pocket is made of elastic material. In this case, the elasticity facilitates the distribution of the liquid because, when this pocket 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 1 ' évacuer pour permettre que la poche vienne contre la paroi de la bonbonne.When the flexible bag is being filled, the volume of the space separating the bag from the internal wall of the cylinder decreases. If air is present in this volume it is necessary to evacuate it to allow the bag 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.To this end, according to one embodiment, the cylinder has an air discharge opening or vent. This embodiment has the advantage of preventing the use of cylinders without a protective pocket.
Dans une variante 1 ' 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 pocket is secured to a ring or a closure cap for the cylinder which comprises at least one air discharge 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 method of filling with liquid food from a bottle intended to be installed in a dispensing fountain of such a liquid, in which the liquid is introduced into a flexible bag, for single use, introduced into the bottle , the flexible pocket being such that at the end of filling it is applied against the internal walls of the cylinder.
De préférence, lors du remplissage, la partie interne de la bonbonne qui se trouve à 1 ' extérieur de la poche est maintenue à pression atmosphérique.Preferably, during filling, the internal part of the bottle which is outside the bag is kept 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 process for dispensing liquid food using a bottle filled in accordance with the process defined above, in which, during the distribution, the internal part of the bottle 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 . Cette poche est, par exemple, en matériau élastique, son volume initial, avant remplissage, étant sensiblement inférieur au volume intérieur de la bonbonne.The invention also relates to a disposable bag for the application of the filling process defined above. This pocket is, for example, made of elastic material, its initial volume, before filling, being substantially less than the interior volume of the cylinder.
La poche comprend, dans une réalisation, un rebord destiné à chevaucher le goulot de la bonbonne. 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 1 ' atmosphère 1 ' espace intérieur de la bonbonne qui est extérieur à la poche.The pocket comprises, in one embodiment, a rim intended to overlap the neck of the cylinder. 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 less than the inside diameter of the neck of the bottle and the cap having minus a hole to put in communication with the atmosphere the interior space of the cylinder which is exterior to the pocket.
Selon une réalisation, cet ensemble est tel que le bouchon présente une ouverture centrale pour 1 ' introduction et l'évacuation de liquide, et cette ouverture centrale est bordée par une paroi intérieure cylindrique dont est solidaire 1 ' ouverture de la poche.According to one embodiment, this assembly is such that the plug has a central opening for the introduction and evacuation of liquid, and this central opening is bordered by a cylindrical inner wall to which the opening of the pocket is attached.
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 1 ' installation de la bonbonne dans une fontaine de distribution de liquide.The plug may further include, to plug its central opening, a central plug cooperating by snap-fastening with the cylindrical inner wall. According to one embodiment, the central plug has a cylindrical part central closed by an inner end cap which is separable from the central cap when installing 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 avecThe 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
1 ' atmosphère 1 ' espace intérieur de la bonbonne qui est extérieur à la poche.1 atmosphere 1 interior space of the cylinder 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 1 ' atmosphère extérieur et 1 ' espace intérieur de la bonbonne qui est extérieur à la poche.The invention also relates to a cylinder for the application of the filling method defined above which comprises at least one hole for relating the external atmosphere and the internal space of the cylinder which is external to the pocket.
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 a drinking liquid dispensing fountain which is characterized in that it comprises a flexible pocket, for single use, filled with the liquid to be dispensed and intended to be introduced into the fountain for this dispensing, the pocket flexible being such that as it empties of the liquid, its wall remains in contact with the free surface of this liquid so that there is practically no empty space inside the pocket, partially drained of liquid.
Le matériau de la paroi de la poche souple est de préférence élastique. Dans une réalisation, la poche comprend un rebord destiné à chevaucher un goulot de bonbonne.The material of the wall of the flexible pocket is preferably elastic. In one embodiment, the pocket includes a rim intended to overlap 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 1 ' introduction et 1 ' 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. 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. 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. Les prédécoupes ont, par exemple, des directions radiales ou une forme de spirale.The pocket can be attached to a bottle cap. In this case, the bottle cap has, for example, a central opening for the introduction and evacuation of liquid, this opening being bordered by a cylindrical inner wall to which the opening of the pocket is attached. 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, molded onto the end rim of the cylindrical inner wall of the plug. The bottle cap may further include, for closing its central opening, a central cap cooperating by snap-fastening with the cylindrical inner wall. The opening edge of the pocket cooperates, in one embodiment, with the end rim of the cylindrical interior wall in the form of a gutter and is held against this rim when the central plug is put in place. In the latter case, a ring can be provided interposed between the end edge of the pocket and an end edge of a sleeve of the central plug. The central cap has, in one embodiment, a central cylindrical part closed by an inner end cap which is separable from the central cap when installing a bottle in a liquid dispensing fountain. The central plug has, according to one embodiment, a central cylindrical part closed by a precut element, these precuts allow the passage of a tube during the installation of a cylinder in a liquid dispensing fountain. 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 1 ' atmosphère 1 ' espace intérieur d'une bonbonne qui est extérieur à la poche.The accessory may include a ring secured to the opening of the pocket, this ring having at least one channel for communicating with the atmosphere 1 inside space of a cylinder which is outside the pocket.

Dans le mode de réalisation de 1 ' 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. 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.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 one not connected to a pipe of a distribution network, one provides a cylinder 10 of substantially rigid plastic material, for example transparent and, to guarantee the cleanliness of the water distributed, 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. 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 cylinder 10 and its diameter is substantially smaller than that of the neck 14 of the cylinder (FIG. 2). Generally, the diameter and length of the expandable or elastic pocket will be determined by the viscosity of the liquid food.
Après remplissage en eau la poche 12 épouse la paroi interne de la bonbonne. Dans cet exemple la poche 12 présente une ouverture bordée par un rebord 16 chevauchant le goulot 14 (figures 1 et 3).After filling with water, the pocket 12 follows the internal wall of the cylinder. In this example, the pocket 12 has an opening bordered by a flange 16 overlapping the neck 14 (Figures 1 and 3).
Pour permettre 1 ' 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 1 ' 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. Après remplissage la bonbonne est fermée par un bouchon 20 (figure 3) de type connu.To allow the application of the bag 12 against the internal wall of the cylinder 10 (Figure 2) it is necessary that during the filling of water in the bag 12 1 air in the cylinder 10 can be evacuated. To this end, in this embodiment, the cylinder 10 has at least one hole (not shown) at any location. 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. Le bouchon 20 comporte une ouverture centrale 26 bordée par une partie cylindrique 28 plongeant à 1 ' intérieur de la bonbonne et 1 ' 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. L'ouverture centrale 26 est fermée par une pastilleThis known plug 20 comprises a skirt 22 retained by snap-fastening by the upper part 24 of the neck, the external wall of which is covered by the rim 16 of the pocket 12. The plug 20 has a central opening 26 bordered by a cylindrical part 28 dipping to 1 'interior of the cylinder and 1 interior end of this cylindrical portion 28 is closed by an inner plug 30 which itself has two flanges 32 and 34. The flange 32 is applied against the inner wall of the cylindrical wall 28 while that the flange 34 is applied against the external wall of the cylindrical wall 28. The internal plug 30 is held at the end of the wall 28 by snap-fastening the flange 34 onto an external bead 36 of this wall 28. The central opening 26 is closed by a patch
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.40. The glue applying the patch 40 against the external wall of the plug 20 is such that when the patch 40 is detached it can no longer be bonded. Thus, a cylinder without a tablet 40 should not be used because it does not include the tablet constituting a guarantee against unauthorized access to the interior of the cylinder.
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 1 ' eau de la bonbonne peut s'évacuer. Le conduit 42 est relié à un robinet (non montré) extérieur.In a manner also known per se, the opening 26, the wall 28 and the plug 30 are intended to cooperate with a distribution tube 42 of the fountain. When the bottle is installed in the fountain, the neck is turned downwards (that is to say in the opposite direction to that shown in FIGS. 1, 2 and 3) and the distribution tube 42 is made to penetrate into the opening 26. The end of this tube 42 which enters the cylinder is closed. It pushes the inner plug 30 which remains, in principle, snapped at the end of the pipe 42 as shown in broken lines in Figure 3. This conduit 42 has, inside the cylinder, openings 44 through which 1 ' water from the cylinder may drain. The duct 42 is connected to an external tap (not shown).
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. 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.When the bottle is extracted from the fountain, the stopper 30 in principle comes back to its place at the end of the cylindrical wall 28, which guarantees the tightness of the bottle after its separation from the fountain. 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 cap are installed before or after filling depending on 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 bottle 12 has the same hygiene guarantees as the water distributed 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 pocket 12 according to the invention. In Figure 4 we see that the bag is full while in Figure 4a the water fills only about a quarter of the volume of the cylinder 10. During the distribution of water, the bag being flexible, it does not outside air does not rise through the liquid because the bag tends to return to its initial low volume. Thus, the water does not come into contact with the outside air, which constitutes 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. 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. 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 1 ' ensemble de la cuve de distribution, ce qui ne peut être le cas avec l'utilisation d'une poche à usage unique.The water contained in the bag 12 is distributed only 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 water distribution. Thus, it can be seen that, with the invention, it is possible to continue to use conventional bottles and caps and that it is not necessary to modify the water distribution fountains, while considerably reducing the risks. water contamination. In fact, during filling, residues which may remain in the cylinder after washing will not have a contaminating effect and the air surrounding the water distribution fountain does not pass through the water distributed. The presence of the pocket 12 also limits the risks for the water distribution tank during filling. In fact, with the conventional filling process, provision is made to return too much water returning from the filled cylinders to the distribution tank. Thus, with the current system, a contaminated cylinder can contaminate the entire distribution tank, which cannot be the case with the use of a disposable bag.
Dans le mode de réalisation de 1 ' 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 conventional fountains are, on the one hand, a drilling of the cylinder according to the variant chosen and, on the other hand, flexible pockets of low price.
Dans le mode de réalisation de 1 ' 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 which is shown in Figure 5 the bag 60 is secured to a cap 62 for closing the bottle (not shown in Figure 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 rébord 22 dans le mode de réalisation représenté sur la figure 3, c'est-à- dire destiné à s ' encliqeter sur le haut du goulot de la bonbonne. 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. 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.This stopper 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 includes an outer rim 70 similar to the rim 22 in the embodiment shown in Figure 3, that is to say intended to snap onto the top of the neck of the cylinder. The edges of the opening of the pocket 60 are secured, for example by gluing or heat-bonding, to the inner face of the wall 64, between the cylindrical wall 68 and the outer rim 70. A central plug 72 is intended to close the central opening 66 after filling of the pocket 60, the cap 62 being installed on the neck of the cylinder.
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 comprises at least one hole 74 for evacuating air which is located between its outer periphery and the pocket 60. This hole 74 makes it possible to evacuate the air located between the pocket 60 and the internal wall of the cylinder when the pocket 60 is filled. This hole 74 also makes it possible to bring air into the cylinder outside the pocket 60, when the latter empties 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 1 ' 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 external cylindrical edge 76 intended to cooperate by snap-fastening with the internal 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 internal 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 part 86 intended to allow the passage of the water distribution tube from the fountain (as described in relation to FIG. 3). The conduit 86 is closed by an internal plug 88 similar to the plug 30 shown in FIG. 3 and having the same role 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. On va maintenant décrire en relation avec les figuresThis plug 88, like the plug 30, is detached from the cylindrical conduit 86 when the cylinder is installed in the fountain and returns to close this conduit when the cylinder is removed from the fountain. However, it may happen that during the operation to extract the fountain bottle, the inner plug 88 (like the inner plug 30 in FIG. 3) does not come back to plug the duct 86 and remains in the pocket 60 to be discarded. However, this malfunction does not constitute a drawback since the pocket 60 must be discarded. We will now describe in relation to the figures
7 et 8 un mode de réalisation de 1 ' 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.7 and 8 an embodiment of the invention which allows the use of a bottle cap of the conventional type, that is to say a cap similar to the cap 20 described in relation to FIG. 3, without however having to drill the cylinder to allow the evacuation of air during filling as well as the introduction of air during water distribution.
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.To this end, the opening of the pocket 90 (FIG. 7) is integral with a ring 92, the lower face of which is intended to bear on the upper edge 94 of the cylinder 96 and this lower face of the ring 92 has at least one groove 98 which opens, on one side, inside 100 of the cylinder, between the pocket 90 and the internal wall of this cylinder, and, on the other side, outside of the cylinder .
Dans 1 ' exemple on prévoit une pluralité de telles rainures 98χ, 982, etc- (figure 8) .In the example, a plurality of such grooves 98χ, 982, etc. - are provided (FIG. 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 plug is not installed during filling of the bag 90 with water. On the other hand, as described in relation to 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 cylinder. However, the plug does not ensure complete airtightness and therefore allows the introduction of air into the space between the pocket 90 and the cylinder 96. This air flow rate is however less than during filling. However, this difference between the flow rates is not a drawback since the water distribution takes place much more slowly than the water filling.
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 bag 90 is filled with water 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 provided 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 distribution of water in the fountain, an overpressure is applied around the pocket in the bottle.
Dans le mode de réalisation de l'invention qui est représenté sur les figures 9, 10 et 11, le bouchon 110 comporte vers 1 ' 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 Figures 9, 10 and 11, the plug 110 has inwardly a sleeve 112, for example similar to the sleeve 68 of the embodiment shown in Figure 6, having its lower end a gutter 114 which is secured by overmolding 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 118]_, II82 régulièrement espacés et dont le rebord comporte des lumières 120χ, etc. également régulièrement espacées.For this purpose, the stopper is, for example, made of polyethylene or polypropylene with a gutter 114 whose bottom has holes 118] _, II82 regularly spaced and whose rim has lights 120χ, 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 gutter is immersed in a bath of molten latex to produce the pocket 116 welded and overmolded in the gutter as shown in FIG. 11.
Dans ce cas, c'est l'ensemble du bouchon et de la poche qui est jetable.In this case, it is the entire cap and pocket which is disposable.
Dans 1 ' exemple représenté sur les figures 12 , 13 etIn the example shown in FIGS. 12, 13 and
14, le bouchon 122 comporte une partie périphérique 122 et une partie centrale 134. La partie périphérique comprend un manchon14, the plug 122 comprises a peripheral part 122 and a central part 134. The peripheral part comprises a sleeve
124 avec à son extrémité une gorge 126 recevant le bord roulé124 with at its end a groove 126 receiving the rolled edge
128 de la poche 130.128 of 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 by means of a ring 132 cooperating with the central part 134 which has an outer sleeve 138 whose end edges 140 press the ring 132 against the rolled edge 128 in order to apply to the bottom of the groove 126 when the central part 134 of the plug is associated with the peripheral part 122 by cooperation of a projection 144 of the sleeve 138 in a groove 146 of the central sleeve of the peripheral part 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 part of the sleeve 124 is greater than the diameter of the rest of the sleeve so as to produce 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 part 134 of the stopper comprises a central sleeve 152 similar to the sleeve 86 of the example in FIG. 6 which ends at its lower end by a frustoconical part 154 having a role similar to the element 88 of FIG. 6, namely that it prevents, or limits, leaks of liquid when the bottle 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. Dans l'exemple montré sur la figure 14, l'élément 154 est découpé en spirale 160.In these two examples, this element 154 has cutouts, or precuts, to allow the tube 42 (FIG. 3) to be able to penetrate inside the carboy. 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. 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 by the fact that the cylindrical central part of the main plug 170 has an upper part 172 of larger diameter into which the central plug 174 engages by click 176 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 ends with a rim 184, facing 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 which is shown in Figure 16 differs from that shown in Figure 15 by the fact that the wall 178 does not have a lower edge. The pocket 192 is welded to the lower part 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 material of the pocket 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 embodiments, it is the flexible nature of the bag which prevents that, during the dispensing of liquid, air can enter the liquid because the upper part of the bag which empties s' collapses by gravity and leaves practically no room for air return. In other words, the upper part folds up and remains practically in contact with the free surface of the remaining liquid. In the case of an elastic pocket, the folds are fewer.
