Description

PROCEDE POUR LA REALISATION D'UN BOUCHON ET BOUCHON OBTENU DESCRIPTION PROCESS FOR PRODUCING A PLUG AND PLUG OBTAINED DESCRIPTION
DOMAINE DE L'INVENTIONFIELD OF THE INVENTION
L'invention concerne un procédé pour la réalisation d'un bouchon en liège, du genre consistant généralement : a) à obtenir un bouchon, taillé directement dans la masse ou reconstitué, délimité par un cylindre et par deux extrémités, conçu pour obturer le col d'une bouteille destinée à contenir tout type de liquide, notamment un vin tranquille ou effervescent ou un spiritueux ; b) à lui appliquer une opération de traitement bactéricide globale ; c) à recouvrir au moins une partie de son cylindre d'une pellicule d'un matériau, notamment du silicone ou de la paraffine, destiné à faciliter son bouchage et son débouchage ; d) à recouvrir au moins l'une de ses extrémités d'une pellicule d'un matériau, notamment un élastomère, de qualité alimentaire ou non, coloré ou non, possédant la propriété d'être perméable aux petites molécules de gaz telles que N2, O2 et CO2 et imperméable aux liquides et aux grosses molécules de gaz à cycles aromatiques.The invention relates to a method for producing a cork stopper, of the type generally consisting in: a) obtaining a stopper, cut directly in the mass or reconstituted, delimited by a cylinder and by two ends, designed to seal the neck a bottle intended to contain any type of liquid, in particular a still or sparkling wine or a spirit; b) to apply to it a global bactericidal treatment operation; c) covering at least part of its cylinder with a film of a material, in particular silicone or paraffin, intended to facilitate its corking and unclogging; d) covering at least one of its ends with a film of a material, in particular an elastomer, of food grade or not, colored or not, having the property of being permeable to small gas molecules such as N 2 , O 2 and CO 2 and impermeable to liquids and large molecules of gases with aromatic cycles.
Le procédé selon l'invention consiste plus particulièrement à accroître l'adhérence de la pellicule destinée à recouvrir au moins l'une des extrémités dudit bouchon.The method according to the invention consists more particularly in increasing the adhesion of the film intended to cover at least one of the ends of said stopper.
L'invention concerne également le bouchon obtenu par la mise en œuvre dudit procédé. ARRIERE PLAN TECHNOLOGIQUEThe invention also relates to the plug obtained by the implementation of said method. TECHNOLOGICAL BACKGROUND
Le liège, qui est constitué de cellules végétales poreuses, laisse passer l'oxygène de l'air ambiant qui est un facteur d'oxydation de la plupart des liquides.Cork, which is made up of porous plant cells, allows oxygen to pass from the ambient air, which is an oxidation factor for most liquids.
La face interne du bouchon s'imprègne, dans le temps, par perfusion, du liquide contenu dans le flacon avec pour conséquences une modification des qualités organoleptiques du contenu (goût de bouchon) et un écoulement de celui-ci hors du flacon conduisant au rejet pur et simple du contenu.The internal face of the stopper is impregnated, over time, by perfusion, with the liquid contained in the bottle with the consequence of a modification of the organoleptic qualities of the contents (stopper taste) and a flow of the latter out of the bottle leading to rejection. outright content.
La face externe du bouchon se détériore, dans le temps, par simple contact avec. l'ambiance humide des caves et l'action cryptogamique des champignons parasites avec pour conséquence le remplacement du bouchon, le réajustement du niveau de liquide évaporé ou le nettoyage du goulot avant l'encapsulation définitive.The external face of the plug deteriorates over time by simple contact with. the humid atmosphere of the cellars and the cryptogamic action of the parasitic mushrooms with as a consequence the replacement of the stopper, the readjustment of the level of evaporated liquid or the cleaning of the neck before the final encapsulation.
Ce problème étant majeur, de nombreuses techniques, pour essayer de remédier à ces divers inconvénients, ont vu le jour.This problem is major, many techniques, to try to remedy these various drawbacks, have emerged.
Parmi celles-ci, on peut citer : a) celle décrite dans le brevet FR1573650 qui consiste, dans le cas d'un bouchon à Champagne reconstitué par encollage :Among these, we can cite: a) that described in patent FR1573650 which consists, in the case of a Champagne cork reconstituted by sizing:
-dans le but d'améliorer sa finition, à poncer son cylindre et à rogner ses deux extrémités ; - dans le but de faciliter sa sortie du goulot au moment du débouchage, à enduire de paraffine la partie de son cylindre qui sera en contact avec le goulot de la bouteille ; - dans le but d'améliorer sa qualité, à enduire une partie du bouchon de produits à base de silicones ; b) celle décrite dans le brevet FR-2644142 qui consiste à recouvrir au moins l'une des faces opposés du bouchon d'un revêtement souple du type élastomère coloré.-in order to improve its finish, sand its cylinder and trim its two ends; - in order to facilitate its exit from the neck when uncorking, to coat with paraffin the part of its cylinder which will be in contact with the neck of the bottle; - in order to improve its quality, to coat part of the cap with silicone-based products; b) that described in patent FR-2644142 which consists in covering at least one of the opposite faces of the plug with a flexible coating of the colored elastomer type.
Le premier document ne traite pas du recouvrement des extrémités du bouchon. En outre, les opérations de ponçage du cylindre et de rognage de ses extrémités ne sont effectuées que pour des raisons de finition après encollage et avant toute opération de traitement du liège. Le deuxième document traite plus particulièrement d'un recouvrement, par un élastomère coloré, des extrémités du bouchon.The first document does not deal with the covering of the ends of the stopper. In addition, the operations of sanding the cylinder and trimming its ends are only carried out for reasons of finishing after gluing and before any cork treatment operation. The second document deals more particularly with a covering, with a colored elastomer, of the ends of the stopper.
Malheureusement, les techniques connues, destinées à recouvrir les extrémités d'un bouchon par une pellicule protectrice, se sont avérées manquant de fiabilité à cause du manque d'adhérence des surfaces en contact provoquant des déchirures et des soulèvements de la pellicule d'élastomère sur les bords lors de sa mise en place sur le goulot de la bouteille et également dans le temps. En effet, dans le processus de fabrication des bouchons il y a deux étapes importantes, la première consistant à traiter le liège avec des produits bactéricides, la deuxième consistant à recouvrir le corps du liège de silicone et de paraffine pour en faciliter le bouchage et le débouchage.Unfortunately, known techniques, intended to cover the ends of a stopper with a protective film, have proved to be unreliable due to the lack of adhesion of the surfaces in contact causing tears and lifts of the elastomer film on the edges when it is placed on the neck of the bottle and also over time. In fact, in the cork manufacturing process there are two important stages, the first consisting in treating the cork with bactericidal products, the second consisting in covering the body of the cork with silicone and paraffin to facilitate the corking and the uncorking.
Les résidus laissés à la surface des bouchons par l'une et/ou l'autre de ces étapes, est à l'origine du manque d'adhérence de la pellicule protectrice, en particulier sur leurs extrémités. RESUME DE L'INVENTION L'invention vise à réaliser une étape nouvelle dans le processus de fabrication d'un bouchon qui consiste, pour accroître l'adhérence de la pellicule sur au moins l'une des extrémités du bouchon qu'elle est destinée à recouvrir, à poncer, ou à rogner, avant la mise en place de ladite pellicule, toute la surface à recouvrir. Outre l'aspect consistant à évacuer de la surface concernée les matières diminuant l'adhérence de la pellicule protectrice, y compris les résidus naturels du liège comme par exemple la subérine, l'opération de ponçage a également pour effet d'ouvrir les cellules du liège augmentant ainsi, de manière importante, les surfaces en contact donc bien évidemment l'adhérence de la pellicule destinée à recouvrir la surface en question. L'invention consiste également à poncer, ou à rogner, pour en accroître l'adhérence, le cylindre du bouchon avant de le recouvrir du même matériau que celui utilisé pour recouvrir ses extrémités.The residues left on the surface of the plugs by one and / or the other of these stages, is the cause of the lack of adhesion of the protective film, in particular on their ends. SUMMARY OF THE INVENTION The invention aims to achieve a new step in the process of manufacturing a stopper which consists, in order to increase the adhesion of the film on at least one of the ends of the stopper that it is intended to cover, sand, or trim, before placing said film, the entire surface to be covered. In addition to the aspect of removing from the surface concerned the materials which reduce the adhesion of the protective film, including the natural residues of cork like for example suberin, the sanding operation also has the effect of opening the cork cells thus increasing, in a significant way, the surfaces in contact therefore obviously the adhesion of the film intended to cover the surface in question. The invention also consists in sanding, or trimming, in order to increase the adhesion, the cylinder of the plug before covering it with the same material as that used to cover its ends.
Elle consiste également, dans ce cas, à recouvrir les extrémités et le cylindre du bouchon au cours de la même opération. PRESENTATION DES FIGURESIt also consists, in this case, in covering the ends and the cylinder of the plug during the same operation. PRESENTATION OF THE FIGURES
