Description

La présente invention concerne un ensemble selon le préambule de la revendication 1.The present invention relates to an assembly according to the preamble of claim 1.

Certaines boissons et notamment la bière sont conditionnées en fûts métalliques consignés. Bien qu'il existe des fûts de différentes capacités, leurs format et contenance sont en voie de normalisation.Certain drinks and in particular beer are packaged in returnable metal barrels. Although there are barrels of different capacities, their format and capacity are being standardized.

Un tel fût à bière en inox est représenté dans la vue découpée de la figure 1.Such a stainless steel beer keg is shown in the cut-out view of FIG. 1.

Ce fût 1 se compose d'une paroi latérale 2 munie de nervures de renforcement 3, 4, de deux fonds 5, 6 dont l'un (6) est équipé d'un embout 7 muni de la valve 8. Cette valve, non représentée en détail, est accessible par la face avant de l'embout 7 et se prolonge par un tube plongeur 9 qui sert au prélèvement ou au remplissage du liquide.This barrel 1 consists of a side wall 2 provided with reinforcing ribs 3, 4, two bottoms 5, 6 one of which (6) is equipped with a nozzle 7 provided with the valve 8. This valve, not shown in detail, is accessible from the front face of the nozzle 7 and is extended by a dip tube 9 which is used for withdrawing or filling the liquid.

L'embout 7 dépasse du fond 6 sur une certaine hauteur qui est néanmoins inférieure à la hauteur du bord 10 du fût.The end piece 7 protrudes from the bottom 6 over a certain height which is nevertheless less than the height of the edge 10 of the barrel.

Les fûts sont souvent manipulés de manière très violente, qu'ils soient pleins ou vides.The barrels are often handled in a very violent way, whether full or empty.

Dans le cas d'un fût de bière, le remplissage se fait à travers la valve. A la fin du remplissage avec la bière, on introduit du gaz carbonique qui remonte dans le fût sous le fond 6 (lorsque le fût est disposé dans la position d'utilisation représentée à la figure 1) de manière à jouer le rôle de gaz propulseur pour le prélèvement de la bière.In the case of a beer keg, filling is done through the valve. At the end of filling with beer, carbon dioxide is introduced which rises in the keg under the bottom 6 (when the keg is disposed in the position of use shown in Figure 1) so as to play the role of propellant for the withdrawal of beer.

Lors de la mise en perce, la valve est reliée à la tuyauterie et à la robinetterie du comptoir. La valve comporte une mécanique de précision et des joints d'étanchéité. Cette valve est l'élément essentiel et le plus fragile du fût de bière. La figure 2 montre, en coupe, la forme de la valve dont la description ne sera pas détaillée.When drilling, the valve is connected to the counter piping and fittings. The valve includes precision mechanics and seals. This valve is the essential and most fragile element of the beer keg. Figure 2 shows, in section, the shape of the valve, the description of which will not be detailed.

Le bon fonctionnement de sa valve est un élément déterminant dans la distribution de la bière dite "à la pression".The proper functioning of its valve is a determining factor in the distribution of so-called "draft" beer.

Du fait de l'importance primordiale de la valve qui ne doit pas fuir et laisser s'échapper du liquide ou du gaz pendant le stockage ou le transport, la valve est vérifiée de façon très soigneuse au moment du retour des fûts à la brasserie.Due to the paramount importance of the valve which must not leak and allow liquid or gas to escape during storage or transport, the valve is checked very carefully when the barrels are returned to the brewery.

Pour protéger la valve, il est connu (US-4 616 763) de munir celle-ci d'une capsule en plastique ou en aluminium. La capsule en plastique est une pièce extrudée. Pour comporter un marquage à la marque du produit, il faut fabriquer des séries importantes pour que le prix unitaire ne devient pas prohibitif. Il n'est donc pas envisageable de munir ces capsules d'indications très précises sur la date de mise en fût de la bière, le type particulier de bière, etc...To protect the valve, it is known (US Pat. No. 4,616,763) to provide the latter with a plastic or aluminum capsule. The plastic capsule is an extruded part. To include a brand marking of the product, it is necessary to manufacture large series so that the unit price does not become prohibitive. It is therefore not possible to provide these capsules with very precise indications on the date of barrel drafting of beer, the particular type of beer, etc.

Enfin, la capsule dont la forme est particulière ne convient qu'à une seule dimension de valve.Finally, the capsule, which has a particular shape, is suitable for only one valve dimension.

Au moment de la mise en perce du fût, il faut arracher la capsule en plastique avec un couteau. On risque ainsi de détériorer les lèvres en caoutchouc de la valve.When piercing the barrel, you must tear off the plastic capsule with a knife. There is thus a risk of damaging the rubber lips of the valve.

Les capes en aluminium, qui protègent les embouts à valve connus, sont des pièces en aluminium découpées dans une bande qui est gaufrée à la date de conditionnement. Le morceau de feuillard d'aluminium est coupant pour les mains qui le manipulent comme pour la valve que la cape est sensée protéger.The aluminum caps, which protect the known valve ends, are aluminum parts cut from a strip which is embossed on the packaging date. The piece of aluminum foil is cutting for the hands handling it as for the valve that the cape is supposed to protect.

Pour mettre le fût en perce, il faut déchirer la capsule d'aluminium avec une pince. Il faut éviter, à tout prix, que des morceaux de métal ne restent sur la valve car ils endommageraient la valve. De manière générale, cet enlèvement, soit de la capsule en matière plastique soit de la cape en aluminium, est une opération désagréable à effectuer et dangereuse.To pierce the barrel, you must tear the aluminum capsule with pliers. Avoid at all costs that pieces of metal remain on the valve as they will damage the valve. Generally, this removal, either of the plastic capsule or of the aluminum cap, is an unpleasant operation to perform and dangerous.

En outre, les systèmes de protection actuels présentent l'inconvénient que les indications portées sur la capsule en plastique sont incomplètes et peu visibles ; lorsque la capsule en plastique ou la cape en aluminium a été enlevée, il n'est plus possible de connaître la marque de bière contenue dans le fût, la date du dernier remplissage et le lieu de conditionnement.In addition, current protection systems have the disadvantage that the indications on the plastic capsule are incomplete and hardly visible; when the plastic cap or the aluminum cap has been removed, it is no longer possible to know the brand of beer contained in the keg, the date of the last filling and the place of packaging.

Il est également connu (voir document EP-A-O 038 468) de fermer des bouteilles à l'aide d'un disque rigide coiffant l'ouverture du col et fixé au col par un manchon thermorétracté s'accrochant au disque et au renforcement du col. Le disque a un diamètre supérieur à celui du renforcement pour être retenu par le manchon thermorétracté.It is also known (see document EP-AO 038 468) to close bottles using a rigid disc covering the neck opening and fixed to the neck by a heat-shrunk sleeve clinging to the disc and strengthening the neck . The disc has a diameter greater than that of the reinforcement to be retained by the heat-shrunk sleeve.

Pour l'ouverture de la bouteille on déchire la partie inférieure du manchon alors que la partie supérieure reste accrochée à la rondelle et forme un capuchon.To open the bottle, the lower part of the sleeve is torn while the upper part remains attached to the washer and forms a cap.

La présente invention a pour but de remédier à ces inconvénients et se proposer de créer un dispositif de protection d'une valve de fût, notamment de fût de bière, permettant de protéger efficacement la valve contre tous les endommagements, qui puisse s'adapter à des valves et embouts de valve de dimensions différentes, et permette d'avoir des indications relatives au contenu du fût, même après que celui-ci ait été mis en perce.The object of the present invention is to remedy these drawbacks and to propose creating a device for protecting a keg valve, in particular beer keg, making it possible to effectively protect the valve against all damage, which can be adapted to valves and valve tips of different dimensions, and allows to have indications relating to the contents of the barrel, even after it has been pierced.

A cet effet, l'invention concerne un dispositif de protection du type ci-dessus, caractérisé par les caractéristiques de la première revendication.To this end, the invention relates to a protection device of the above type, characterized by the features of the first claim.

Ce dispositif se met en place de manière très simple et de manière automatique ou manuelle, et il suffit de placer la plaquette sur la valve puis d'emmancher le manchon thermorétractable par-dessus l'embout de la valve et par-dessus la plaquette. On fait alors rétracter le manchon, par exemple à l'aide d'un courant d'air chaud. Le manchon emprisonne la plaquette et s'accroche à l'embout.This device is set up in a very simple manner and automatically or manually, and it suffices to place the plate on the valve and then to fit the heat-shrinkable sleeve over the end of the valve and over the plate. The sleeve is then retracted, for example using a stream of hot air. The sleeve traps the plate and hangs on the end piece.

La plaquette a une forme correspondant à celle de la valve ou de l'embout, c'est-à-dire, en général, une forme circulaire. Toutefois, si d'autres formes d'embout devaient exister, il est simple de réaliser une plaquette de forme différente.The plate has a shape corresponding to that of the valve or the nozzle, that is to say, in general, a circular shape. However, if other forms of tip should exist, it is simple to make a plate of different shape.

Comme la plaquette n'a pas à déborder par rapport à la face avant de l'embout muni de la valve, il est possible d'utiliser la même plaquette pour différents types de fûts.As the plate does not have to project beyond the front face of the nozzle fitted with the valve, it is possible to use the same plate for different types of barrels.

Les indications relatives au produit contenu dans le fût peuvent être imprimées ou marquées sur le manchon. Cette impression peut se faire à plat, avant la réalisation du manchon. Ainsi, il est particulièrement intéressant d'imprimer des bandes de matière thermorétractable mono-orientée, à plat, pour avoir une meilleure qualité d'impression, puis de replier cette bande pour former un tube. Le tube est lui même mis en bobine et est débité à la longueur des manchons dans la machine de mise en place automatique ou manuellement si cette mise en place se fait ainsi.The indications relating to the product contained in the barrel can be printed or marked on the sleeve. This printing can be done flat, before making the sleeve. Thus, it is particularly interesting to print strips of heat-shrinkable mono-oriented material, flat, to have a better printing quality, then to fold this strip to form a tube. The tube is itself reeled and cut to the length of the sleeves in the automatic positioning machine or manually if this positioning is done in this way.

La bande d'arrachage est prédécoupée ou plus généralement réalisée dans la bande avant ou après impression, de sorte que le manchon, même avant thermorétraction, comporte cette bande d'arrachage. Cela facilite l'intervention de l'utilisateur qui met le fût en perce ; celui-ci n'a pas à utiliser d'outils particuliers et notamment de couteau.The tear strip is precut or more generally made in the strip before or after printing, so that the sleeve, even before heat shrinking, comprises this tear strip. This facilitates the intervention of the user who pierces the barrel; this one does not have to use particular tools and in particular of knife.

Grâce à la partie "inférieure" du manchon qui reste fixée à l'embout, l'utilisateur a, à tout moment, les indications relatives au produit contenu dans le fût. Il peut connaître sa nature exacte, sa date de mise dans le fût, etc... Pour le fabricant, cela simplifie le conditionnement car il n'a pas à coller d'étiquette sur le fond du fût, étiquette qui, lorsque les fûts sont stockés à l'extérieur, risque d'être détériorés par la pluie ou encore qu'il faut enlever au moment du retour des fûts puisque le fût ne reçoit pas nécessairement toujours le même type de produit ou de bière.Thanks to the "lower" part of the sleeve which remains fixed to the end piece, the user has, at any time, the indications relating to the product contained in the barrel. It can know its exact nature, its date of placing in the barrel, etc ... For the manufacturer, this simplifies the packaging because it does not have to stick a label on the bottom of the barrel, label which, when the barrels are stored outside, risk of being damaged by the rain or even that must be removed when returning the kegs since the keg does not necessarily always receive the same type of product or beer.

La présente invention sera décrite de manière plus détaillée à l'aide des dessins annexés, dans lesquels :

  • la figure 1 est une vue en perspective arrachée d'un exemple de fût à bière auquel s'applique l'invention,
  • la figure 2 est une vue de détail de la partie supérieure du fût de la figure 1, coupée au niveau de la valve,
  • la figure 3 montre la valve d'un fût sur laquelle a été placé le dispositif de protection avant thermorétraction,
  • la figure 4 montre la valve et le dispositif de protection après thermorétraction,
  • la figure 5 montre un manchon appartenant au dispositif de protection, manchon qui est replié à plat.
The present invention will be described in more detail with the aid of the appended drawings, in which:
  • FIG. 1 is a cutaway perspective view of an example of a beer keg to which the invention applies,
  • FIG. 2 is a detailed view of the upper part of the barrel of FIG. 1, cut at the level of the valve,
  • FIG. 3 shows the valve of a barrel on which the protection device before heat shrinking has been placed,
  • FIG. 4 shows the valve and the protection device after heat shrinking,
  • FIG. 5 shows a sleeve belonging to the protection device, a sleeve which is folded flat.

Selon la figure 3, le dispositif de protection se compose d'une plaquette de recouvrement 11 placée sur la valve 8 portée par l'embout tubulaire 7 solidaire du fond 6 du fût. Le dispositif comporte également un manchon thermorétractable 12 coiffant la plaquette 11, l'embout 7 et la valve 8 pour maintenir la plaquette 11 appliquée contre la face avant de l'embout 7 par-dessus la valve 8.According to Figure 3, the protection device consists of a cover plate 11 placed on the valve 8 carried by the tubular end piece 7 secured to the bottom 6 of the barrel. The device also includes a heat-shrinkable sleeve 12 covering the wafer 11, the end piece 7 and the valve 8 to keep the wafer 11 applied against the front face of the end piece 7 over the valve 8.

La figure 3 montre le dispositif de protection (11, 12) après sa mise en place.Figure 3 shows the protection device (11, 12) after its installation.

Lorsque le manchon 12 est mis en place comme mis en place comme décrit ci-dessus, il n'est pas encore thermorétracté. Il est suffisamment grand pour s'emmancher facilement sur l'embout 7 et la plaquette 11.When the sleeve 12 is put in place as put in place as described above, it is not yet shrunk. It is large enough to fit easily on the nozzle 7 and the plate 11.

Ce manchon 12 est, de préférence, en une matière synthétique mono-orientée et en particulier en polychlorure de vinyle PVC. La plaquette 11 est en général une plaquette de forme circulaire et d'un diamètre légèrement plus faible que le bord supérieur de l'embout et de la valve 7, 8. Il peut également avoir d'autres formes si, dans des cas particuliers, l'embout devait avoir une forme polygonale ou autre.This sleeve 12 is preferably made of a mono-oriented synthetic material and in particular of polyvinyl chloride PVC. The wafer 11 is generally a wafer of circular shape and of a diameter slightly smaller than the upper edge of the end piece and of the valve 7, 8. It can also have other shapes if, in particular cases, the tip should have a polygonal or other shape.

La figure 5 montre une vue en perspective d'un manchon 12 après sa réalisation.Figure 5 shows a perspective view of a sleeve 12 after its completion.

En effet, il est préférable, pour réaliser le manchon 12, de partir d'une bande de matière thermorétractable, d'imprimer cette bande en la munissant des informations 13 relatives à la nature du produit, sa date de fabrication ou de conditionnement, etc ... Il est également intéressant de munir la bande de lignes transversales prédécoupées 14 ainsi que d'une bande d'arrachage 15. La bande d'arrachage 15 rejoint, de préférence, le bord supérieur 16 du futur manchon 12 à la prédécoupe transversale 14.Indeed, it is preferable, to produce the sleeve 12, from a strip of heat-shrinkable material, to print this strip by providing it with information 13 relating to the nature of the product, its date of manufacture or of packaging, etc. ... It is also advantageous to provide the strip with precut transverse lines 14 as well as with a tear strip 15. The tear strip 15 preferably joins the upper edge 16 of the future sleeve 12 with transverse precut 14.

Une fois ces différentes opérations réalisées sur la bande, celle-ci est repliée de manière que ces bords 17, 18 se recouvrent et soient collés pour former un manchon. Le manchon est alors, de préférence, enroulé sur une bobine et est débité au moment de son utilisation. On obtient alors le manchon à plat 12 apparaissant à la figure 5.Once these various operations have been carried out on the strip, the latter is folded back so that these edges 17, 18 overlap and are glued to form a sleeve. The sleeve is then preferably wound on a reel and is cut off when it is used. This gives the flat sleeve 12 appearing in FIG. 5.

Sur ce manchon, il y aura une partie inférieure 19 et une partie supérieure 20. Après rétraction et comme cela apparaît sur la figure 4, pour mettre le fût en perce et pouvoir enlever la plaquette 11 dégageant la valve 8, on déchire la bande d'arrachage 15 jusqu'à la prédécoupe 14. Cela permet d'enlever simplement la partie "supérieure" 20 du manchon alors que la partie inférieure 19 reste accrochée sur l'embout. Il est ainsi possible, après mise en perce, d'avoir toujours les indications 13 sur l'embout du fût.On this sleeve, there will be a lower part 19 and an upper part 20. After shrinking and as it appears in FIG. 4, to pierce the barrel and be able to remove the plate 11 releasing the valve 8, the strip d is torn. 'tearing off 15 up to the precut 14. This makes it possible to simply remove the "upper" part 20 of the sleeve while the lower part 19 remains attached to the end piece. It is thus possible, after drilling, to always have the indications 13 on the end of the barrel.

De façon avantageuse, la partie inférieure 19 peut comporter une bande d'arrachage 21 partant du bord inférieur 22 du manchon et arrivant jusqu'à la prédécoupe transversale 14. Cette bande 21 est non-alignée sur la bande d'arrachage 15. Ainsi, la bande d'arrachage 21 permet d'enlever facilement la partie inférieure 19 sans nécessiter d'outils. Comme les bandes d'arrachage 15, 21 ne sont pas situées dans le prolongement l'une de l'autre, il n'y a aucun risque qu'au moment de l'enlèvement de la bande d'arrachage 15, on détache également la partie inférieure 19 du manchon.Advantageously, the lower part 19 may comprise a tear strip 21 starting from the lower edge 22 of the sleeve and arriving up to the transverse precut 14. This strip 21 is non-aligned with the tear strip 15. Thus, the tear strip 21 makes it easy to remove the lower part 19 without the need for tools. As the tear strips 15, 21 are not located in the extension of each other, there is no risk that when removing the tear strip 15, it is also detached the lower part 19 of the sleeve.

Bien que la description faite ci-dessus concerne principalement un fût de bière, l'invention peut s'appliquer dans les mêmes conditions à tout fût analogue, comportant une valve comme celle d'un fût de bière.Although the description given above mainly concerns a keg of beer, the invention can be applied under the same conditions to any similar keg, comprising a valve like that of a keg of beer.
