Description

CAPSULE POUR LA PREPARATION D'UNE BOISSON ET DISPOSITIF CAPSULE FOR PREPARING A BEVERAGE AND DEVICE
Domaine de l'inventionField of the invention
La présente invention se situe dans le domaine de la préparation de boissons, p.ex. à base de café, par extraction d'une dose concentrée, p. ex. de café moulu, contenue dans une capsule. Elle se rapporte plus particulièrement aux doses utilisées à cet effet ainsi qu'aux dispositifs utilisant de telles doses.The present invention is in the field of the preparation of beverages, eg coffee-based, by extraction of a concentrated dose, e.g. ex. ground coffee, contained in a capsule. It relates more particularly to the doses used for this purpose as well as devices using such doses.
Etat de la technique Des capsules et des machines fonctionnant selon le principe précité existent depuis de nombreuses décennies.State of the art Capsules and machines operating according to the aforementioned principle have existed for many decades.
Les brevets US 2 899 886, US 2 968 560, US 3 403 617 et US 3 607 297 décrivent des dispositifs où la capsule est initialement perforée en plusieurs endroits, puis traversée par de l'eau sous pression.US Pat. Nos. 2,899,886, US 2,968,560, US 3,403,617 and US 3,607,297 disclose devices in which the capsule is initially perforated in a plurality of locations and then passed through water under pressure.
La capsule décrite dans le brevet CH 605 293 ou dans le brevet EP 0 242 556 B1 comporte une membrane dans sa partie inférieure. De l'eau sous pression est initialement introduite dans la partie supérieure de la capsule, après percement de ladite capsule au moyen d'un élément tranchant (p.ex. une lame), ce qui entraîne un gonflement de la capsule, principalement au niveau de la membrane. A partir d'une certaine pression, la membrane se déchire, autorisant de la sorte l'écoulement d'un mélange eau-café.The capsule described in patent CH 605 293 or in patent EP 0 242 556 B1 comprises a membrane in its lower part. Water under pressure is initially introduced into the upper part of the capsule, after piercing said capsule by means of a cutting element (eg a blade), which causes the capsule to swell, mainly at the level of the capsule. of the membrane. From a certain pressure, the membrane tears, thus allowing the flow of a water-coffee mixture.
D'autres capsules munies d'une membrane sont décrites dans les documents brevets suivants : EP 0 468 079 A, EP 0 806 373 A, EP 0 554 469 A.Other capsules provided with a membrane are described in the following patent documents: EP 0 468 079 A, EP 0 806 373 A, EP 0 554 469 A.
Exposé général de l'inventionGeneral presentation of the invention
Un des objectifs de la présente invention réside dans une amélioration du mélange eau-café qui se produit à l'intérieur de la capsule.One of the objectives of the present invention is to improve the water-coffee mixture which occurs inside the capsule.
Un autre objectif réside dans une amélioration de la sécurité liée à l'utilisation des dispositifs pour capsules. Un autre objectif consiste à simplifier l'entretien des dispositifs pour capsules.Another objective is to improve the safety associated with the use of capsule devices. Another goal is to simplify the maintenance of capsule devices.
Cet objectif est atteint en dotant la paroi latérale et/ou la face supérieure de la capsule de plusieurs reliefs auto-perçants.This objective is achieved by providing the lateral wall and / or the upper face of the capsule of several self-piercing reliefs.
Les reliefs sont disposés et conçus de manière à se perforer lors de leur déformation, de préférence simultanément, par un élément déformant qui prend appui sur la capsule, comme par exemple un mandrin.The reliefs are arranged and designed to perforate during deformation, preferably simultaneously, by a deforming element which bears on the capsule, such as a mandrel.
Dans la présente invention les reliefs peuvent être formés par gaufrage, étampage, thermoformage ou tout autre méthode adaptée au but recherché.In the present invention the reliefs can be formed by embossing, stamping, thermoforming or any other method adapted to the desired purpose.
Les reliefs se caractérisent en ce qu'il forment une surface relativement faible, dans tous les cas bien inférieure à la surface totale de la face latérale et/ou de face supérieure de la capsule. Ainsi, lorsque l'élément déformant est actionné, c'est au niveau des reliefs que la capsule est percée par leur déformation qui résulte dans une auto-perforation.The reliefs are characterized in that they form a relatively small surface, in all cases much smaller than the total surface of the lateral face and / or upper face of the capsule. Thus, when the deforming element is actuated, it is at the level of the reliefs that the capsule is pierced by their deformation which results in a self-perforation.
La capsule selon l'invention peut être avantageusement utilisée dans un dispositif comprenant une cage à capsule dépourvue d'éléments tranchants, le simple contact de la paroi interne avec le ou les reliefs auto-perçants assurant un écoulement du liquide à travers la capsule.The capsule according to the invention can be advantageously used in a device comprising a capsule cage devoid of cutting elements, the simple contact of the inner wall with the self-piercing relief or reliefs ensuring a liquid flow through the capsule.
Exposé détaillé de l'inventionDetailed exposition of the invention
L'invention est décrite plus en détail ci-après au moyen d'exemples non-limitatifs illustrés par les figures suivantes :The invention is described in more detail below by means of non-limiting examples illustrated by the following figures:
La figure 1 illustre un premier exemple de capsule selon l'invention La figure 2 illustre un vue de détail de la capsule de la figure 1 Les figures 3 et 4 illustrent des vues en coupe de la capsule Les figures 5 et 7 illustrent schématiquement un exemple de dispositif utilisant une capsule selon l'inventionFIG. 1 illustrates a first example of a capsule according to the invention. FIG. 2 illustrates a detail view of the capsule of FIG. 1. FIGS. 3 and 4 illustrate sectional views of the capsule. FIGS. 5 and 7 schematically illustrate an example of a device using a capsule according to the invention

Les figures 1 à 4 illustrent des capsules comprenant un corps creux 1 , une paroi latérale 2, une face supérieure 3 et une face inférieure 4, cette dernière comportant une membrane d'extraction (non illustrée).Figures 1 to 4 illustrate capsules comprising a hollow body 1, a side wall 2, an upper face 3 and a lower face 4, the latter having an extraction membrane (not shown).
Comme on peut le voir sur les figures 1 à 4, la face supérieure 3 comporte une série de reliefs 5 qui sont auto-perçants par déformation, comme il sera expliqué plus loin dans la présente description.As can be seen in Figures 1 to 4, the upper face 3 comprises a series of reliefs 5 which are self-piercing by deformation, as will be explained later in this description.
Chaque relief 5 a une caractéristique d'auto-percement lorsque l'on applique un élément de pression sur la zone qui comprend lesdits reliefs 5.Each relief 5 has a self-piercing characteristic when a pressure element is applied to the area which comprises said reliefs 5.
Les figures 5 à 8 illustrent schématiquement un dispositif utilisant les capsules selon l'invention et comprenant des moyens permettant l'activation de l'auto- percement des reliefs 5. Plus précisément, le dispositif comprend un mandrin 8 déplaçable axialement (voir les figures 5 à 7) , ledit mandrin 8 comportant une paroi de pression 9 qui vient d'appuyer contre les reliefs lors du déplacement relatif du mandrin 8 par rapport à la capsule 1. Ainsi, lorsque le mandrin 8 est déplacé en direction de la capsule, la paroi 9 vient d'appuyer contre les reliefs 5 et les déforme provocant ainsi leur auto-percement, et libérant le passage pour l'eau.Figures 5 to 8 schematically illustrate a device using the capsules according to the invention and comprising means for activating the self-drilling reliefs 5. More specifically, the device comprises a mandrel 8 axially displaceable (see Figures 5 7), said mandrel 8 having a pressure wall 9 which bears against the reliefs during the relative movement of the mandrel 8 relative to the capsule 1. Thus, when the mandrel 8 is moved towards the capsule, the wall 9 has just pressed against the reliefs 5 and deforms thereby provoking their self-piercing, and releasing the passage for water.
La présence de plusieurs reliefs 5 en différents endroits de la capsule, et par conséquent de plusieurs lieux de perforation, a pour avantage d'améliorer considérablement le mélange eau-café à l'intérieur de la capsule.The presence of several reliefs 5 in different parts of the capsule, and therefore of several places of perforation, has the advantage of considerably improving the water-coffee mixture inside the capsule.
L'avantage du système selon l'invention est sa simplicité de construction et d'emploi. En outre, il n'est plus nécessaire de prévoir des moyens de coupe ou de perçage sur le mandrin, comme cela est le cas dans les systèmes connus. Ainsi, l'invention est aussi plus simple à entretenir et nettoyer.The advantage of the system according to the invention is its simplicity of construction and use. In addition, it is no longer necessary to provide cutting means or drilling on the mandrel, as is the case in known systems. Thus, the invention is also simpler to maintain and clean.
L'invention ne se limite pas aux exemples illustrés.The invention is not limited to the illustrated examples.
N'importe quelle forme de relief peut être envisagée. Idem pour la distribution et le nombre des reliefs.Any form of relief can be considered. Ditto for the distribution and the number of reliefs.
De préférence, la capsule est formée d'un matériau biodégradable.Preferably, the capsule is formed of a biodegradable material.
Avantageusement, le matériau biodégradable peut être d'origine végétale.Advantageously, the biodegradable material may be of plant origin.
Selon une variante, le matériau comprend les composants suivants : Amidon (> 70 %), fibres, protéines, lipides, glycérine d'origine végétale, résines biodégradables.According to one variant, the material comprises the following components: Starch (> 70%), fibers, proteins, lipids, glycerin of vegetable origin, biodegradable resins.
Selon une autre variante, le matériau comprend les composants suivants : Amidon (> 70 %), fibres, protéines, lipides, résine biodégradable, colorant minéral.According to another variant, the material comprises the following components: starch (> 70%), fibers, proteins, lipids, biodegradable resin, mineral dye.
A relever enfin que la capsule selon l'invention peut également être utilisée avec des dispositifs de l'état de la technique qui sont dotés de lames pour l'introduction de l'eau dans la capsule. Finally, note that the capsule according to the invention can also be used with devices of the state of the art which are provided with blades for introducing water into the capsule.
