Description
DISPOSITIF A RECIPIENT RIGIDE ET POCHE CYLINDRIQUE SOUPLE POUR LE CONDITIONNEMENT DE FLUIDES. DEVICE WITH RIGID CONTAINER AND FLEXIBLE CYLINDRICAL POCKET FOR PACKAGING OF FLUIDS.
La présente invention concerne un dispositif de conditionnement et de distribution de produit fluide, et plus particulièrement un nouveau dispositif de conditionnement et de distribution de produit fluide, liquide ou pâteux, du type comportant une poche souple placée dans un récipient rigide, associée à une pompe ou une valve, assurant le stockage du produit fluide à l'abri de l'air et sa distribution dans de bonnes conditions d'efficacité.The present invention relates to a device for packaging and dispensing a fluid product, and more particularly to a new device for packaging and dispensing a fluid product, liquid or pasty, of the type comprising a flexible bag placed in a rigid container, associated with a pump. or a valve, ensuring the storage of the fluid product away from air and its distribution under good conditions of efficiency.
Les dispositifs de conditionnement et de distribution de fluide du type flacon-poche sont bien connus. Ces dispositifs comportent généralement un récipient à coque rigide dans lequel est placée une poche souple rétractable, qui se rétracte au fur et à mesure que le produit en est extrait. L'expulsion du produit hors de la poche peut être obtenue au moyen d'une pompe "airless" ou sans reprise d'air, ou sous la pression d'un gaz propulseur agissant dans le flacon, sur la paroi de la poche. Dans le cas de l'expulsion du produit hors de la poche au moyen d'une pompe sans reprise d'air, un évent est prévu, généralement dans le fond ou dans le col du flacon, pour permettre à l'air extérieur de pénétrer dans l'espace situé entre le flacon et la poche à chaque actionnement de la pompe et permettre ainsi à la poche de se rétracter en maintenant une pression suffisante sur ses parois. Un exemple de réalisation suivant cette technique est décrit dans le brevet FR 2.723.356 relatif à un dispositif comportant une poche en matière plastique souple, telle que polyéthylène ou polypropylène, dans un récipient rigide dont le col comporte une entrée d'air.Devices for packaging and dispensing fluid of the bottle-pocket type are well known. These devices generally include a rigid shell container in which a flexible retractable pocket is placed, which retracts as the product is extracted therefrom. The expulsion of the product from the bag can be obtained by means of an "airless" pump or without air intake, or under the pressure of a propellant acting in the bottle, on the wall of the bag. In the case of the expulsion of the product out of the bag by means of a pump without air intake, a vent is provided, generally at the bottom or in the neck of the bottle, to allow outside air to enter in the space between the bottle and the bag on each actuation of the pump and thus allow the bag to retract while maintaining sufficient pressure on its walls. An exemplary embodiment according to this technique is described in patent FR 2,723,356 relating to a device comprising a pocket made of flexible plastic material, such as polyethylene or polypropylene, in a rigid container whose neck has an air inlet.
Un autre exemple de poche en matière plastique souple dont la paroi est fixée sur un col annulaire, est décrit dans le brevet US 6.189.744. La poche est tubulaire dans sa partie haute, près du col, et aplatie dans sa partie basse. Les difficultés rencontrées dans cette technique sont souvent liées aux plis que peut former la paroi de la poche lors de sa rétractation, qui peuvent limiter l'efficacité de la distribution du fluide en formant des volumes de rétention de produit, et à la difficulté d'assurer une étanchéité satisfaisante de la poche permettant de préserver l'intégrité du produit qui y est contenu. Les produits que contiennent les poches sont en effet souvent sensibles à l'oxydation sous l'action de l'oxygène de l'air et peuvent se dégrader si de l'air s'introduit dans la poche. Les défauts d' étanchéité se rencontrent souvent au niveau de la jonction de la poche et de la pompe. Ils peuvent aussi résulter d'une certaine porosité des matériaux utilisés pour la réalisation de la poche. Enfin, les plis formés par la paroi de la poche au cours de sa rétractation peuvent entraîner des déchirures susceptibles de laisser passer de l'air qui atteint alors le produit contenu dans la poche.Another example of a flexible plastic bag, the wall of which is fixed to an annular neck, is described in US Patent 6,189,744. The pocket is tubular in its upper part, near the neck, and flattened in its lower part. The difficulties encountered in this technique are often linked to the folds that the wall of the pocket can form during its retraction, which can limit the efficiency of the distribution of the fluid by forming product retention volumes, and to the difficulty of ensure a satisfactory seal of the bag to preserve the integrity of the product contained therein. The products contained in the bags are indeed often sensitive to oxidation under the action of oxygen in the air and can degrade if air is introduced into the bag. Sealing faults are often encountered at the junction of the bag and the pump. They can also result from a certain porosity of the materials used for the production of the bag. Finally, the folds formed by the wall of the pocket during its retraction can cause tears capable of letting air pass which then reaches the product contained in the pocket.
Un autre exemple de réalisation de flacon-poche est décrit dans le brevet FR 2.770.834, qui concerne un dispositif destiné à éviter le percement et la déchirure de la poche lors de sa vidange. A cet effet, la poche, réalisée en matière souple telle que feuille plastique ou d'aluminium, contient un flotteur libre empêchant une trop forte rétractation de la poche et limitant ainsi les risques de déchirure. Les poches réalisées en feuilles d'aluminium ou en matières multicouches du type plastique / aluminium, comme celles utilisées dans le dispositif du brevet précité, présentent de bonnes qualités d' étanchéité de leur paroi, mais la présence du flotteur peut gêner l'évacuation du produit hors de la poche et limiter l'efficacité du dispositif d'extraction. De plus, les poches d'aluminium sont réalisées sous forme de feuilles superposées, soudées par leur bord, s 'adaptant généralement sur un col ou une bague rigide assurant la liaison avec la pompe, ou la valve, et le récipient rigide. La fabrication de telles poches est relativement simple, et diverses mentions et dessins peuvent y être imprimés aisément, mais ce système présente l'inconvénient que la feuille, avant remplissage, a une forme aplatie, exigeant de recourir à un outillage complexe spécialement adapté pour pouvoir y introduire le produit. Les opérations de remplissage impliquent généralement de devoir faire d'abord le vide dans la poche avant de procéder à un remplissage partiel, puis à opérer dans une dernière étape sous gaz neutre. Les poches en matière plastique, par exemple en polyéthylène ou polypropylène comme celle décrite dans la demande de brevet WO 97.09124, permettent de simplifier l'opération de remplissage de la poche, mais ne garantissent pas une étanchéité satisfaisante susceptible de convenir au condition- nement de produits très fragiles se dégradant au contact de l'air. Or les techniques d'extrusion ou d'extrusion soufflage utilisées pour la fabrication de telles poches en matière plastique sont totalement inadaptées aux poches comportant une ou plusieurs feuilles métalliques. De plus, il est difficile d'obtenir et de maintenir une bonne étanchéité des soudures des bords des feuilles métalliques, par exemple d'aluminium en raison des déformations et des tensions auxquelles elles sont soumises en cours d'utilisation.Another exemplary embodiment of a pocket bottle is described in patent FR 2,770,834, which relates to a device intended to prevent piercing and tearing of the pocket during its emptying. To this end, the pocket, made of flexible material such as plastic or aluminum foil, contains a free float preventing excessive shrinkage of the pocket and thus limiting the risks of tearing. The bags made of aluminum sheets or of multilayer materials of the plastic / aluminum type, such as those used in the device of the aforementioned patent, have good sealing qualities of their wall, but the presence of the float can hinder the evacuation of the product out of the bag and limit the efficiency of the extraction device. In addition, the aluminum pockets are made in the form of superimposed sheets, welded by their edge, generally adapting to a neck or a rigid ring ensuring the connection with the pump, or the valve, and the rigid container. The manufacture of such bags is relatively simple, and various mentions and drawings can be easily printed there, but this system has the disadvantage that the sheet, before filling, has a flattened shape, requiring the use of complex tools specially adapted to be able to introduce the product. The filling operations generally imply having to first empty the bag before carrying out partial filling, then operating in a last step under neutral gas. The plastic bags, for example polyethylene or polypropylene bags like that described in patent application WO 97.09124, make it possible to simplify the filling operation of the bag, but do not guarantee a satisfactory seal capable of being suitable for the packaging of very fragile products degrading on contact with air. However, the extrusion or blow molding techniques used for the manufacture of such plastic bags are totally unsuitable for bags comprising one or more metal sheets. In addition, it is difficult to obtain and maintain good sealing of the welds of the edges of the metal sheets, for example of aluminum, due to the deformations and tensions to which they are subjected during use.
La présente invention a précisément pour objet un dispo- sitif de conditionnement et de distribution de produit fluide, liquide ou pâteux, du type comportant une poche souple étanche placée dans un récipient rigide, associée à une pompe ou une valve, assurant une très bonne facilité de remplissage de la poche sans qu'il soit nécessaire de recourir à un outillage complexe ou spécialement adapté.The object of the present invention is precisely a device for packaging and dispensing a fluid, liquid or pasty product, of the type comprising a watertight flexible pouch placed in a rigid container, associated with a pump or a valve, ensuring very good ease. filling the bag without the need for complex or specially adapted tools.
L'invention a aussi pour objet un dispositif de conditionnement et de distribution de produit fluide du type comportant une poche souple étanche placée dans un récipient rigide, assurant un parfait conditionnement du produit au moyen d'une excellente étanchéité de la poche. L'invention a enfin pour objet un procédé de fabrication d'une poche cylindrique comme indiqué ci-dessus.The invention also relates to a device for packaging and dispensing a fluid product of the type comprising a sealed flexible pouch placed in a rigid container, ensuring perfect packaging of the product by means of excellent sealing of the pouch. The invention finally relates to a method of manufacturing a cylindrical pocket as indicated above.
Le dispositif de conditionnement et de distribution de produit fluide suivant la présente invention est du type comportant une poche souple étanche placée dans un récipient rigide, associée à une pompe ou une valve, et se distingue en ce que la poche comprend une paroi cylindrique constituée par au moins une feuille métallique ou de matière plastique enroulée suivant un cylindre dont les bords sont fixés de manière étanche à deux flasques dont l'un forme le fond de la poche et l'autre une bague de fixation au récipient et à la pompe ou à la valve .The device for packaging and dispensing a fluid product according to the present invention is of the type comprising a sealed flexible pocket placed in a rigid container, associated with a pump or a valve, and is distinguished in that the pocket comprises a cylindrical wall constituted by at least one metal or plastic sheet wound in a cylinder, the edges of which are tightly fixed to two flanges, one of which forms the bottom of the bag and the other a ring for fixing to the container and to the pump or to the valve.
Suivant une forme préférentielle de réalisation, la poche cylindrique comprend un complexe multicouche associant plusieurs films métalliques ou un film métallique, de préférence en aluminium, revêtu d'un film plastique sur l'une au moins de ses faces. Ce complexe multicouche est enroulé sur deux flasques en métal ou en matière plastique. Une forme particulièrement avantageuse de réalisation comprend une feuille d'aluminium intercalée entre deux films plastiques.According to a preferred embodiment, the cylindrical pocket comprises a multilayer complex associating several metallic films or a metallic film, preferably made of aluminum, coated with a plastic film on at least one of its faces. This multi-layer complex is wound on two metal or plastic flanges. A particularly advantageous embodiment comprises an aluminum foil sandwiched between two plastic films.
Les films plastiques utilisés dans les complexes multicouches peuvent être choisis parmi un polyethylene, un polypropylène, un polyamide, etc.The plastic films used in the multilayer complexes can be chosen from polyethylene, polypropylene, polyamide, etc.
La feuille multicouche est fixée par ses bords à la périphérie de chaque flasque, et refermée suivant une génératrice du cylindre.The multilayer sheet is fixed by its edges to the periphery of each flange, and closed along a generatrix of the cylinder.
Un tel revêtement composite multicouche s'avère particulièrement utile lorsqu'une étanchéité rigoureuse est indispensable, ou lorsque la nature du produit contenu dans la poche l'exige.Such a multilayer composite coating proves to be particularly useful when a tight seal is essential, or when the nature of the product contained in the pocket requires it.
Suivant une variante, on peut utiliser une feuille d'aluminium enroulée sur deux flasques en métal ou en matière plastique, deux bords opposés de la feuille étant soudés l'un sur l'autre suivant une génératrice du cylindre. Suivant une autre forme de réalisation de l'invention, la feuille multicouche est un complexe matière plastique / polymère barrière / matière plastique, et par exemple un film EVOH intercalé entre deux films de polyethylene ou de polypropylène. L'EVOH est un polymère éthylène - alcool vinylique offrant de bonnes caractéristiques de barrière aux gaz, en particulier à l'oxygène et à la vapeur d'eau.According to a variant, an aluminum foil wound on two metal or plastic flanges can be used, two opposite edges of the sheet being welded to one another along a generatrix of the cylinder. According to another embodiment of the invention, the multilayer sheet is a plastic material / barrier polymer / plastic material complex, and for example an EVOH film interposed between two films of polyethylene or polypropylene. EVOH is an ethylene-vinyl alcohol polymer offering good barrier characteristics to gases, in particular to oxygen and water vapor.
Dans un autre exemple conforme à l'invention, on peut utiliser un complexe à quatre couches, soit polyethylene / polyamide / aluminium / téréphtalate de polyethylene.In another example according to the invention, a four-layer complex can be used, namely polyethylene / polyamide / aluminum / polyethylene terephthalate.
Comme indiqué ci-dessus, la feuille métallique, ou la feuille multicouche, est fixée sur la périphérie de chacun des deux flasques, de préférence par collage ou par soudage, selon la nature du matériau utilisé pour les flasques. L'un des deux flasques forme un disque plein et constitue le fond de la poche, tandis que l'autre présente une ouverture et sert de bague de fixation, d'une part au flacon rigide, d'autre part à la pompe ou à la valve utilisée pour l'extraction du produit contenu dans la poche. L'ouverture pratiquée dans le flasque servant de bague est de préférence axiale, mais elle peut être déportée, selon la forme du cylindre et les effets recherchés.As indicated above, the metal sheet, or the multilayer sheet, is fixed to the periphery of each of the two flanges, preferably by gluing or by welding, depending on the nature of the material used for the flanges. One of the two flanges forms a solid disc and constitutes the bottom of the pocket, while the other has an opening and serves as a fixing ring, on the one hand to the rigid bottle, on the other hand to the pump or to the valve used for the extraction of the product contained in the bag. The opening in the flange serving as a ring is preferably axial, but it can be offset, depending on the shape of the cylinder and the desired effects.
Le cylindre formé par la feuille métallique, ou le complexe multicouche, et les deux flasques est de préférence un cylindre droit à section circulaire, les flasques étant alors en forme de disques circulaires, mais d'autres formes peuvent être réalisées sans difficulté, et par exemple les flasques peuvent avoir une forme elliptique, ou une forme quelconque continue ou polygonale, selon l'effet esthétique recherché ou imposé par la forme du flacon rigide. Les deux flasques ont de préférence la même forme pour faciliter la fixation de la feuille métallique, mais le cas échéant ils peuvent avoir une forme différente, ou une forme homothétique.The cylinder formed by the metal sheet, or the multilayer complex, and the two flanges is preferably a straight cylinder with circular section, the flanges then being in the form of circular disks, but other shapes can be produced without difficulty, and by example the flanges can have an elliptical shape, or any continuous or polygonal shape, depending on the aesthetic effect sought or imposed by the shape of the rigid bottle. The two flanges preferably have the same shape to facilitate the fixing of the metal sheet, but if necessary they can have a different shape, or a homothetic shape.
Les flasques peuvent être métalliques ou réalisés en matière plastique, par exemple par moulage. Il est également possible de donner au flasque formant le fond une forme évidée en son centre, le flasque ayant alors une forme torique, dont l'ouverture centrale peut être fermée par le film de la paroi cylindrique, ou un autre film. La fabrication de la poche cylindrique suivant la présente invention s'effectue au moyen d'un appareillage usuel permettant d'enrouler une feuille métallique, plastique ou multicouche, par ses bords sur la périphérie des deux flasques maintenus sur un même axe l'un en face de l'autre. La feuille est découpée à la longueur voulue, correspondant à la circonférence des flasques augmentée d'une longueur suffisante pour permettre la fermeture par soudure bord à bord, après collage des bords latéraux sur la périphérie des flasques. Le flacon-poche suivant la présente invention présente l'avantage de pouvoir être facilement rempli sans qu'il soit nécessaire de disposer d'un outillage complexe, contrairement aux poches en aluminium classiques. Conformément à la présente invention, le remplissage peut s'effectuer avec un outillage standard, par simple gravité, ce qui assure une très bonne régularité de remplissage. De plus, la grande liberté de forme de la poche permet de l'adapter aisément à des flacons rigides de formes variées.The flanges can be metallic or made of plastic, for example by molding. he is also possible to give the flange forming the bottom a hollow shape in its center, the flange then having a toric shape, the central opening of which can be closed by the film of the cylindrical wall, or another film. The manufacture of the cylindrical pocket according to the present invention is carried out by means of a conventional apparatus making it possible to wind a metallic, plastic or multilayer sheet, by its edges on the periphery of the two flanges maintained on the same axis, one in opposite each other. The sheet is cut to the desired length, corresponding to the circumference of the flanges increased by a length sufficient to allow closing by edge-to-edge welding, after bonding of the lateral edges on the periphery of the flanges. The pocket bottle according to the present invention has the advantage of being easy to fill without the need for complex tools, unlike conventional aluminum pockets. In accordance with the present invention, filling can be carried out with standard tools, by simple gravity, which ensures very good filling regularity. In addition, the great freedom of shape of the bag makes it easy to adapt it to rigid bottles of various shapes.
Diverses mentions et dessins peuvent être apposés sur la poche, comme dans le cas des poches classiques en aluminium de forme aplatie, la seule contrainte étant de le faire avant l'opération de fixation de la feuille sur les flasques.Various statements and designs can be affixed to the pocket, as in the case of conventional flattened aluminum pockets, the only constraint being to do so before the operation of fixing the sheet to the flanges.
Malgré l'absence d'élasticité de la feuille métallique, le taux de restitution du produit, c'est-à-dire le rapport entre le volume de produit introduit dans la poche lors du remplissage et le volume extrait au cours de l'utilisation, est excellent, supérieur à 90 %, et supérieur à celui généralement obtenu avec des poches plates classiques.Despite the lack of elasticity of the metal foil, the rate of return of the product, that is to say the ratio between the volume of product introduced into the bag during filling and the volume extracted during use , is excellent, greater than 90%, and greater than that generally obtained with conventional flat pockets.
En raison de sa forme cylindrique s ' appuyant sur les deux flasques rigides, lors de son utilisation et de l'extraction du produit qui y est contenu, la poche ne se plisse pas comme dans le cas des poches plates en aluminium, mais se rétracte régulièrement en limitant les risques de fissuration ou de déchirure. De plus, le nombre de soudures est limité par rapport à une poche en aluminium classique, et la fiabilité de la poche s'en trouve améliorée.Due to its cylindrical shape pressing on the two rigid flanges, during its use and extraction of the product contained therein, the pocket does not wrinkle as in the case of flat aluminum pockets, but shrinks regularly, limiting the risk of cracking or tearing. In addition, the number of welds is limited compared to a conventional aluminum pocket, and the reliability of the pocket is improved.
Un des avantages du dispositif de la présente invention est que la poche peut être assemblée au flacon sans pliage préalable, et donc sans risque de détérioration de ses qualités d' étanchéité. De plus, l'assemblage de la poche au flacon peut être effectué à cadences élevées.One of the advantages of the device of the present invention is that the bag can be assembled to the bottle without prior folding, and therefore without risk of deterioration of its sealing qualities. In addition, the assembly of the bag to the bottle can be carried out at high rates.
Un exemple de réalisation de poche souple en aluminium pour dispositif du type flacon poche conforme à la présente invention est décrit ci-après en référence aux dessins annexés qui représentent :An exemplary embodiment of a flexible aluminum pouch for a device of the pouch bottle type in accordance with the present invention is described below with reference to the appended drawings which represent:
Figure 1 : une vue en coupe d'une poche suivant la présente invention comportant une feuille en complexe multicouche fixée sur un fond et une bague en matière thermoplastique. Figure 2 : une vue en coupe et en perspective de la poche de la Figure 1.Figure 1: a sectional view of a pocket according to the present invention comprising a sheet of multilayer complex attached to a bottom and a ring of thermoplastic material. Figure 2: a sectional and perspective view of the pocket of Figure 1.
Figure 3 : une vue en perspective de la poche de la Figure 1 montrant comment s'effectue la soudure longitudinale de la feuille d'aluminium constituant la paroi de la poche. Figure 4 : une vue en coupe de la poche de la Figure 1 mise en place dans un flacon rigide comportant une pompe.Figure 3: a perspective view of the pocket of Figure 1 showing how the longitudinal welding of the aluminum foil constituting the wall of the pocket takes place. Figure 4: a sectional view of the pocket of Figure 1 placed in a rigid bottle with a pump.
La poche (1) représentée sur la Figure 1 comprend une paroi cylindrique (2) constituée par une feuille d'aluminium enroulée sur les deux flasques (3) et (4) . Le flasque inférieur (3) a la forme d'un disque plein (5) à bord relevé formant une surface annulaire (6) sur laquelle est fixée le bord de la feuille (2) par collage. Le flasque supérieur (4) a la forme d'une bague traversée en son centre par un orifice (7) et comportant un bord relevé formant une surface annulaire (8) sur laquelle est collé l'autre bord de la feuille (2), limitée par un rebord (9) de diamètre légèrement supérieur à celui de la paroi cylindrique (2) .The pocket (1) shown in Figure 1 comprises a cylindrical wall (2) formed by an aluminum foil wound on the two flanges (3) and (4). The lower flange (3) has the shape of a solid disc (5) with raised edge forming an annular surface (6) on which the edge of the sheet (2) is fixed by gluing. The upper flange (4) has the shape of a ring crossed in its center by an orifice (7) and comprising a raised edge forming an annular surface (8) on which the other edge of the sheet (2) is stuck, limited by a rim (9) of diameter slightly greater than that of the cylindrical wall (2).
Comme le montre la Figure 3, les deux bords (2', 2") de la feuille d'aluminium (2), découpée à la longueur voulue, sont soudés l'un sur l'autre suivant une génératrice du cylindre, après collage des deux bordures latérales (2a, 2b) sur les surfaces annulaires, (6) et (8) respectivement, des flasques .As shown in Figure 3, the two edges (2 ', 2 ") of the aluminum sheet (2), cut to the desired length, are welded to each other along a generatrix of the cylinder, after bonding of the two lateral edges (2a, 2b) on the annular surfaces, (6) and (8) respectively, the flanges.
La poche (1) est introduite dans un flacon cylindrique (10) comme le représente la Figure 4. Le bord (9) de la bague (4) vient se fixer par encliquetage dans une rainure (11) formée dans la surface interne de la paroi (12) du flacon rigide.The pocket (1) is introduced into a cylindrical bottle (10) as shown in Figure 4. The edge (9) of the ring (4) is fixed by snap-fastening in a groove (11) formed in the internal surface of the wall (12) of the rigid bottle.
Une pompe (13) complétée par un poussoir (14) est montée de manière étanche sur le col de la poche (1). L' étanchéité peut être assurée de manière usuelle, par exemple au moyen d'un joint annulaire (15). Une pression sur le poussoir (14) provoque la sortie d'une dose par la buse (16), entraînant une rétractation de la poche (1) . Un évent pratiqué dans le flacon permet à l'air extérieur d'entre dans le volume situé entre le flacon (10) et la poche (1) et à la poche de se rétracter au fur et à mesure que l'on actionne le poussoir (14).A pump (13) supplemented by a pusher (14) is mounted in leaktight manner on the neck of the pocket (1). Sealing can be ensured in the usual way, for example by means of an annular seal (15). A pressure on the pusher (14) causes the exit of a dose by the nozzle (16), causing a retraction of the bag (1). A vent in the bottle allows the outside air to enter the volume between the bottle (10) and the pocket (1) and the pocket to retract as the pusher is actuated (14).
La poche utilisée dans le dispositif de la Figure 4 comporte un flasque (3) dont le fond est évidé, l'ouverture étant masquée par une feuille d'aluminium (17) améliorant la souplesse de la poche (1) . The pocket used in the device of Figure 4 has a flange (3) whose bottom is hollowed out, the opening being masked by an aluminum sheet (17) improving the flexibility of the pocket (1).
