Description

« CAPSULE POUR LA PREPARATION D'UNE BOISSON TELLE QUE DU  "CAPSULE FOR THE PREPARATION OF A BEVERAGE SUCH AS

Domaine de l'invention Field of the invention
La présente invention a pour objet une capsule destinée à recevoir une substance pour la préparation d'une boisson, pour une machine à café ayant un logement pour la capsule et un piston muni de picots répartis dans une zone d'action pour presser la capsule dans le logement de la machine en s'appuyant contre la capsule, la capsule ayant un fond et une paroi latérale s 'inscrivant globalement dans un tronc de cône dont l'ouverture munie d'un rebord est couverte par un opercule après chargement du produit.  The present invention relates to a capsule for receiving a substance for the preparation of a beverage, for a coffee machine having a housing for the capsule and a piston provided with pins distributed in an action zone for pressing the capsule in the housing of the machine bearing against the capsule, the capsule having a bottom and a side wall s' enrolling globally in a truncated cone whose opening provided with a rim is covered by a cap after loading the product.
Etat de la technique  State of the art
On connaît une multiplicité de capsules ayant les formes les plus diverses pour être utilisées dans une machine dans laquelle la capsule est percée pour injecter de l'eau chaude / vapeur d'eau et préparer une boisson telle que du café ou une infusion.  A multiplicity of capsules having the most diverse shapes are known to be used in a machine in which the capsule is pierced to inject hot water / steam and prepare a beverage such as coffee or an infusion.
Selon le type de capsule, suivant qu'il s'agit d'une capsule non pré-percée, les picots percent le fond ou d'une capsule prépercée, les picots viennent dans une gorge circulaire du fond correspondant la zone d'action des picots qui, dans ce cas, ne touchent pas le fond.  Depending on the type of capsule, depending on whether it is a non-pre-pierced capsule, the pimples pierce the bottom or a pre-drilled capsule, the pimples come in a circular groove of the bottom corresponding to the action zone of the pimples which, in this case, do not touch the bottom.
Les capsules pré-percées doivent être fermées hermétiquement par un emballage supplémentaire ou suremballage, ce qui complique la fabrication par cette étape d'emballage après le remplissage de la capsule.  The pre-drilled capsules must be sealed with additional packaging or overpack, which complicates the manufacturing by this packaging step after filling the capsule.
La conservation des arômes n'est pas complètement garantie car les arômes diffusent à travers les pré-perçages dans le volume de l'emballage.  The conservation of flavors is not completely guaranteed because the aromas diffuse through the pre-boring in the volume of the packaging.
L'encombrement de la capsule ainsi emballée ou suremballée est important ce qui augmente d'autant le volume de conditionnement des capsules dans des boîtes et au final le volume de déchets.  The size of the capsule thus packaged or overpacked is important, which increases the volume of packaging capsules in boxes and ultimately the volume of waste.
Dans le cas de capsules non pré-percées, la fabrication est difficile car il faut diminuer l'épaisseur du fond pour permettre le perçage par les picots. En résumé, le problème de ces capsules est la complexité de leur forme et leur conditionnement pour conserver la substance contenue dans la capsule de façon aussi hermétique que possible pour la protéger contre la détérioration des caractéristiques organoleptiques du produit et plus généralement conserver la qualité du produit, pour obtenir une boisson aussi proche que possible d'une boisson telle que du café ou une infusion préparée directement à partir d'une substance fraîche (poudre de café ou produit d'infusion). In the case of non-pre-drilled capsules, the manufacture is difficult because it is necessary to reduce the thickness of the bottom to allow drilling by the pins. In summary, the problem of these capsules is the complexity of their shape and their packaging to preserve the substance contained in the capsule as hermetically as possible to protect it against the deterioration of the organoleptic characteristics of the product and more generally to maintain the quality of the product , to obtain a drink as close as possible to a drink such as coffee or an infusion prepared directly from a fresh substance (coffee powder or infusion product).
But de l'invention Purpose of the invention
La présente invention a pour but de développer une capsule du type ci-dessus, simple, réduisant le conditionnement servant à conserver l'herméticité sans compliquer la fabrication et l'utilisation de la capsule ou rendre plus difficile sa mise en place ou son extraction de la cavité de la machine et dans cette optique, 1 "invention a également pour but de réaliser une capsule biodégradable et en particulier une capsule compostable.  The present invention aims to develop a capsule of the above type, simple, reducing the packaging used to maintain hermeticity without complicating the manufacture and use of the capsule or make it more difficult to set up or extract it. In this view, the invention also aims at producing a biodegradable capsule and in particular a compostable capsule.
Exposé et avantages de l'invention Description and advantages of the invention
A cet effet, l'invention a pour objet une capsule du type défini ci-dessus, caractérisé en ce que le fond est subdivisé en une zone centrale et une zone périphérique comportant des secteurs périphériques bordés par une ligne de rupture laissant entre les secteurs périphériques une bande de liaison avec la zone centrale, et chaque secteur restant relié au fond par une zone de liaison, la zone périphérique étant dans la zone d'action des picots du piston pour être déformée par les picots poussant au moins certains secteurs périphériques pour les ouvrir en déchirant les lignes de rupture.  For this purpose, the subject of the invention is a capsule of the type defined above, characterized in that the bottom is subdivided into a central zone and a peripheral zone comprising peripheral sectors bordered by a rupture line leaving between the peripheral sectors. a connecting strip with the central zone, and each sector remaining connected to the bottom by a connecting zone, the peripheral zone being in the zone of action of the pins of the piston to be deformed by the pins pushing at least some peripheral sectors for the open by tearing the break lines.
La capsule selon l'invention a l'avantage d'être d'une parfaite herméticité sans pour autant compliquer le percement du fond. Elle ne risque pas d'être déformée et de rester coincée dans la cavité de la machine, grâce à la rigidité du fond dont tous les secteurs en contact avec les picots s'ouvrent et s'escamotent vers l'intérieur ; le picot qui rencontre éventuellement une bande de liaison repousse celle-ci, ouvrant les lignes de rupture voisines sans déformer le fond de manière irréversible, ce qui garantit des entrées de liquide réparties sur le fond, répartissant régulièrement le liquide dans le produit. La capsule selon l'invention a l'avantage de réduire au minimum le conditionnement puisqu 'étant parfaitement étanche, elle ne nécessite à priori aucun suremballage ce qui réduit les déchets mis à la poubelle. The capsule according to the invention has the advantage of being perfectly hermetic without complicating the piercing of the bottom. It is not likely to be deformed and get stuck in the cavity of the machine, thanks to the rigidity of the bottom of which all sectors in contact with the pins open and retract inwards; the pin which eventually encounters a connecting strip pushes it, opening the neighboring rupture lines without deforming the bottom irreversibly, which ensures liquid inlets distributed on the bottom, regularly distributing the liquid in the product. The capsule according to the invention has the advantage of minimizing the packaging since it is perfectly sealed, it does not require a priori overpackaging which reduces the waste put in the trash.
Les secteurs périphériques sont en nombre supérieur à celui des picots du piston pour qu'au moins certains des picots rencontrent un secteur périphérique pour l'ouvrir alors que le cas échéant le picot arrivant sur une bande de liaison entre deux secteurs déforme le fond et cette déformation déchire au moins partiellement l'une ou l'autre des lignes de rupture les plus proches pour ouvrir au moins partiellement le secteur correspondant.  The peripheral sectors are in number greater than that of the pins of the piston so that at least some of the pins meet a peripheral sector to open it while, if necessary, the pin arriving on a connecting strip between two sectors deforms the bottom and this deformation at least partially tears one or the other of the nearest breaking lines to at least partially open the corresponding sector.
Comme selon une autre caractéristique, les bandes de liaison relient le bord extérieur du fond à sa zone centrale à travers la zone périphérique, elles renforcent le fond et évitent toute déformation globale ; si un picot rencontre une bande de liaison, il ne déforme que cette bande de liaison sans déformer l'ensemble du fond. Cette déformation étant en général élastique, il n'y a pas de déformation globale de la capsule risquant de coincer celle-ci dans son logement de la machine.  As according to another characteristic, the connecting strips connect the outer edge of the bottom to its central zone through the peripheral zone, they reinforce the bottom and avoid any global deformation; if a pin encounters a connecting strip, it deforms only this connecting strip without deforming the entire bottom. This deformation is generally elastic, there is no overall deformation of the capsule may trap it in its housing of the machine.
Suivant une autre caractéristique avantageuse, la ligne de rupture d'un secteur est formée d'un segment extérieur et de deux branches orientées vers la zone centrale, les branches de deux lignes de rupture voisines laissant entre elles la bande de liaison.  According to another advantageous characteristic, the breaking line of a sector is formed of an outer segment and two branches oriented towards the central zone, the branches of two adjacent rupture lines leaving between them the connecting strip.
De façon avantageuse, la zone de liaison relie le secteur à la zone centrale du fond ou inversement, la zone de liaison relie le sec- teur au bord du fond. Dans les deux cas, sous la poussée d'un picot, le secteur se déchire suivant la ligne de rupture et s'ouvre vers l'intérieur de la capsule pour constituer un passage pour le liquide.  Advantageously, the connection zone connects the sector to the central zone of the bottom or vice versa, the connection zone connects the sector to the edge of the bottom. In both cases, under the pressure of a pin, the sector tears along the line of rupture and opens towards the inside of the capsule to form a passage for the liquid.
Suivant une autre caractéristique avantageuse, les secteurs périphériques sont identiques et leur nombre est supérieur à celui des picots du piston. D'une manière particulièrement avantageuse, le nombre des secteurs périphériques est supérieur d'une unité à celui des picots. Ainsi, d'une part, tous les picots ne risquent pas de rencontrer des bandes de liaison, le risque étant limité à la rencontre d'un picot et d'une bande de liaison, les autres picots agissant directement sur les secteurs périphériques pour les ouvrir. Ainsi, globalement et sur toute la périphérie du fond, il y aura des passages pour le liquide, ce qui évite les passages préférentiels à travers la masse de produit contenu dans la capsule. According to another advantageous characteristic, the peripheral sectors are identical and their number is greater than that of the pins of the piston. In a particularly advantageous manner, the number of peripheral sectors is one unit higher than that of the pins. Thus, on the one hand, all the pins are not likely to encounter binding strips, the risk being limited to the meeting of a pin and a connecting strip, the other pins acting directly on the peripheral sectors for open. Thus, globally and over the entire periphery of the bottom, there will be passages for the liquid, which avoids the preferential passages through the mass of product contained in the capsule.
Suivant une autre caractéristique avantageuse, la cap- suie est réalisée par un procédé d'injection-compression, la capsule entière étant réalisée par injection et la ligne de rupture obtenue par compression à partir de l'intérieur de la capsule. La ligne de rupture est ainsi l'empreinte de l'outil de compression qui ne traverse la paroi du fond que sur une partie de son épaisseur, par exemple à « mi-chair ».  According to another advantageous characteristic, the capture is carried out by an injection-compression process, the whole capsule being produced by injection and the rupture line obtained by compression from the inside of the capsule. The line of rupture is thus the impression of the compression tool which crosses the wall of the bottom only over a part of its thickness, for example to "half-flesh".
On a ainsi l'avantage d'un fond extérieur parfaitement lisse et d'une ligne de rupture ouverte vers l'intérieur du fond, ce qui évite tout accrochage de la capsule sur une aspérité et le risque d'ouverture partielle ou de blessure du fond de la capsule au cours des manipulations de remplissage et de conditionnement.  This has the advantage of a perfectly smooth outer bottom and a break line open towards the inside of the bottom, which avoids any attachment of the capsule on an asperity and the risk of partial opening or injury of the Bottom of the capsule during filling and conditioning manipulations.
Selon une autre caractéristique avantageuse, la paroi latérale a forme de révolution autour de l'axe de la capsule a une partie supérieure tronconique reliée au fond par une partie renforcée composée d'une ceinture tronconique d'angle supérieur à celui de la partie supérieure, rejoignant une surface cylindrique elle-même reliée au fond par une couronne tronconique d'angle supérieur à celui de la paroi latérale, la ceinture tronconique étant renforcée côté intérieur de la capsule par un premier ensemble de goussets orientés radialement et formant des appuis pour l'empilage de capsules vides les unes dans les autres et la surface cylindrique et la couronne tronconique étant renforcées inté- rieurement par un deuxième ensemble de goussets orientés radialement et décalés angulairement par rapport au gousset du premier ensemble.  According to another advantageous characteristic, the side wall has a shape of revolution around the axis of the capsule has a frustoconical upper portion connected to the bottom by a reinforced portion consisting of a frustoconical belt angle greater than that of the upper part, joining a cylindrical surface itself connected to the bottom by a frustoconical crown angle greater than that of the side wall, the frustoconical belt being reinforced on the inside of the capsule by a first set of gussets oriented radially and forming supports for the stacking empty capsules into each other and the cylindrical surface and the frustoconical crown being internally reinforced by a second set of gussets oriented radially and angularly offset from the gusset of the first set.
La capsule dont la paroi latérale globalement de forme tronconique a ainsi été renforcée évite d'être déformée par le piston et de rester coincée dans la cavité de la machine. Les éléments de renfor- cernent se réalisent directement au moulage sans nécessiter de moule complexe avec des parties mobiles.  The capsule whose generally frustoconical side wall has been reinforced avoids being deformed by the piston and remain stuck in the cavity of the machine. Reinforcing elements are directly molded without requiring a complex mold with moving parts.
Suivant une autre caractéristique avantageuse le fond est composé d'une zone centrale et d'une zone périphérique rejoignant la paroi latérale par un bord, la zone périphérique étant occupée par les secteurs et la zone centrale étant formée d'une couronne bombée dans le prolongement de la forme bombée de la zone périphérique et reliée à une couronne plate entourant un dôme creux. According to another advantageous characteristic the bottom is composed of a central zone and a peripheral zone joining the lateral wall by an edge, the peripheral zone being occupied by the sectors and the central zone being formed of a domed crown in the extension of the curved shape of the peripheral zone and connected to a flat crown surrounding a hollow dome.
Le fond ainsi structuré est particulièrement rigide pour résister à la poussée du piston pour que cette poussée ouvre les secteurs sans déformer le fond et permettent de transmettre les éventuels efforts induits par le piston dont un picot rencontrerait une partie du fond autre qu'un secteur ; l'effort sera alors transmis de manière répartie en périphérie à la partie « inférieure » de la paroi de la capsule pour être ainsi appliqué de façon répartie sur toute la périphérie de la paroi conique, même dans le cas d'une capsule biodégradable ou compos- table.  The bottom thus structured is particularly rigid to withstand the thrust of the piston so that this thrust opens the sectors without deforming the bottom and allow to transmit the possible forces induced by the piston which a pin meet a part of the bottom other than a sector; the force will then be transmitted distributed peripherally to the "lower" part of the wall of the capsule so as to be applied in a distributed manner over the entire periphery of the conical wall, even in the case of a biodegradable or composite capsule - table.
En effet, suivant une autre caractéristique, l'invention permet de réaliser des capsules biodégradables et notamment compos- tables. Une telle capsule est caractérisée en ce que la capsule est en un matériau biodégradable et notamment compostable, choisi dans un groupe incluant le PLA et les mélanges de celui-ci et la partie supérieure tronconique et la partie inférieure sont d'épaisseur réduite par rapport à celle de la partie inférieure et du fond.  According to another characteristic, the invention makes it possible to produce biodegradable and in particular composable capsules. Such a capsule is characterized in that the capsule is made of a biodegradable and in particular compostable material, chosen from a group including PLA and mixtures thereof and the frustoconical upper part and the lower part are of reduced thickness compared to that of the lower part and the bottom.
Suivant une autre caractéristique avantageuse, la capsule caractérisée en ce que le gousset du second ensemble est situé sensiblement au milieu du segment extérieur de la ligne de rupture d'un secteur périphérique.  According to another advantageous characteristic, the capsule characterized in that the gusset of the second set is located substantially in the middle of the outer segment of the rupture line of a peripheral sector.
Cette disposition du gousset du deuxième ensemble permet avec les goussets du premier ensemble et les bandes de liaison, d'entourer rigidement les secteurs périphériques de façon que sous la poussée d'un picot la poussée s'exerce uniquement sur le secteur périphérique rencontré par le picot. Dans le cas d'un picot rencontrant une partie autre qu'un secteur du fond, le fond sera légèrement déformé et cette déformation rompra la ligne de rupture de part et d'autre de ce point d'appui du picot.  This arrangement of the gusset of the second assembly makes it possible, with the gussets of the first assembly and the connecting strips, to rigidly surround the peripheral sectors so that, under the thrust of a pin, the thrust is exerted solely on the peripheral sector encountered by the pin. In the case of a pin meeting a portion other than a sector of the bottom, the bottom will be slightly deformed and this deformation will break the line of rupture on either side of this point of support of the pin.

Description de modes de réalisation de l'invention  Description of Embodiments of the Invention
Selon la figure 1 , l'invention a pour objet une capsule 1 pour une machine de préparation d'une boisson telle que du café ou une infusion. Cette capsule 1 a une forme globale de révolution autour de son axe XX avec un fond 1 1 , une paroi latérale 12, tronconique, et un dessus ouvert, muni d'un rebord 13 recevant un opercule fermant hermétiquement l'ouverture pour emprisonner le produit dans la capsule.  According to Figure 1, the invention relates to a capsule 1 for a machine for preparing a drink such as coffee or an infusion. This capsule 1 has an overall shape of revolution about its axis XX with a bottom January 1, a side wall 12, frustoconical, and an open top, provided with a flange 13 receiving a cap sealing the opening to trap the product in the capsule.
Par convention, pour simplifier la description de la capsule 1 , il sera fait référence à l'orientation verticale de la capsule représentée aux figures 1 , 2 et suivantes, le bord 13 pour l'opercule étant situé en haut et le fond 1 1 en bas. Plus précisément et selon la vue en coupe axiale de la figure 2 et la vue de dessus de la figure 3, la capsule 1 a un rebord 13 dont le dessus est plat pour y fixer l'opercule ; le dessous du rebord 13 comporte des lèvres d'étanchéité pour recevoir le bord du piston et réa- liser l'étanchéité. By convention, to simplify the description of the capsule 1, reference will be made to the vertical orientation of the capsule shown in Figures 1, 2 and following, the edge 13 for the cap being located at the top and the bottom 1 1 in low. More specifically and according to the axial sectional view of Figure 2 and the top view of Figure 3, the capsule 1 has a flange 13 whose top is flat to fix the lid; the underside of the rim 13 has sealing lips for receiving the edge of the piston and for sealing.
La capsule a une paroi latérale 12 formée d'une partie supérieure tronconique 121 et d'une partie inférieure renforcée, ayant une ceinture tronconique 122 munie intérieurement d'un premier ensemble de goussets 21 , régulièrement répartis par groupes de trois. Les goussets 21 dans les plans radiaux renforcent la ceinture tronconique 122 et forment par leur coin, des appuis 21 1 pour l'empilage de capsules vides (figure 6).  The capsule has a side wall 12 formed of a frustoconical upper portion 121 and a reinforced lower portion, having a frustoconical belt 122 provided internally with a first set of gussets 21, regularly distributed in groups of three. The gussets 21 in the radial planes reinforce the frustoconical belt 122 and form by their corner, supports 21 1 for stacking empty capsules (Figure 6).
La ceinture tronconique 122 d'angle de cône supérieur à celui de la partie 121 rejoint une surface cylindrique 123 se poursui- vant par une couronne tronconique 124 d'angle de cône relativement grand rejoignant le fond 1 1 par son bord 1 13.  The frustoconical belt 122 cone angle greater than that of the portion 121 joined a cylindrical surface 123 continuing with a frustoconical crown 124 of relatively large cone angle joining the bottom 1 1 by its edge January 13.
La surface cylindrique 123 et la surface tronconique 124 sont munies intérieurement d'un second ensemble de goussets 22 dans des plans radiaux, assurant le renforcement de la partie inférieure et du fond 1 1 selon une répartition qui apparaît plus clairement à la figure 3.  The cylindrical surface 123 and the frustoconical surface 124 are internally provided with a second set of gussets 22 in radial planes, ensuring the reinforcement of the lower part and the bottom 1 1 in a distribution which appears more clearly in FIG.
Les parties 121 , 122, 123, 124 de la paroi latérale 12 ont une épaisseur réduite à l'exception des goussets 21 , 22 et d'un anneau 23 renforçant intérieurement la surface cylindrique 123.  The portions 121, 122, 123, 124 of the side wall 12 have a reduced thickness except for the gussets 21, 22 and a ring 23 internally reinforcing the cylindrical surface 123.
La capsule 1 selon l'invention est une capsule non pré- percée dont le fond 1 1 , sans ouverture, est hermétique avant l'action du piston de la machine.  The capsule 1 according to the invention is a non-pre-pierced capsule whose bottom 1 1, without opening, is hermetic before the action of the piston of the machine.
La figure 3 est une vue de dessus de la capsule 1 montrant la structure intérieure de sa partie inférieure et de son fond 1 1 , selon l'orientation en rotation autour de son axe vertical de symétrie de rotation XX de la capsule. A la figure 2, le plan de coupe est le plan (II II) de la figure 3 qui n'est pas un plan de symétrie ni même de pseudosymétrie comme les plans (VA, VA) et (VB, VB).  Figure 3 is a top view of the capsule 1 showing the inner structure of its lower part and its bottom 1 1, according to the rotational orientation about its vertical axis of rotational symmetry XX of the capsule. In Figure 2, the section plane is the plane (II II) of Figure 3 which is not a plane of symmetry or even pseudosymmetry as the planes (VA, VA) and (VB, VB).
A l'intérieur du rebord 13 apparaissent les goussets 21 et leurs appuis 21 1 ainsi que les goussets 22. Les goussets 22 au nombre de quatre sont répartis régulièrement en laissant entre eux chaque fois un quadrant dans lequel se trouvent trois goussets 21 eux aussi régulièrement répartis dans chaque quadrant sans être dans le prolongement radial des goussets 22. Inside the rim 13 appear the gussets 21 and their supports 21 1 and the gussets 22. The gussets 22 four in number are regularly distributed leaving each other between them a quadrant in which there are three gussets 21 also regularly distributed in each quadrant without being in the radial extension of the gussets 22.
Le fond 1 1 est subdivisé géométriquement en une zone centrale 1 1 1 et une zone périphérique 1 12 allant jusqu'au bord 1 13 du fond, à sa jonction avec la couronne tronconique 124 de la paroi latérale 12. Schématiquement, la zone centrale 1 1 1 est délimitée par un cercle et la zone périphérique 1 12 est celle comprise entre ce cercle et le bord 1 13 du fond.  The bottom 1 1 is subdivided geometrically into a central zone 1 1 1 and a peripheral zone 1 12 up to the edge 1 13 of the bottom, at its junction with the frustoconical crown 124 of the side wall 12. Schematically, the central zone 1 1 1 is delimited by a circle and the peripheral zone 1 12 is that between this circle and the edge 1 13 of the bottom.
Le fond 1 1 comporte des secteurs périphériques 14 situés dans la zone périphérique 1 12 et délimités chacun par une ligne de rupture 15 composée d'un segment extérieur 151 , sensiblement parallèle au bord du fond et de deux branches 152, radiales ou globalement orientées vers la zone centrale de façon à délimiter le secteur 14 sur trois côtés en laissant la continuité de la matière du fond vers la zone centrale 1 1 1. Cette continuité de la matière est schématisée par une ligne en traits interrompus correspondant à une zone de liaison 17 qui s'étend sur une certaine largeur dans la direction radiale.  The bottom 1 1 has peripheral sectors 14 located in the peripheral zone 1 12 and each delimited by a break line 15 composed of an outer segment 151, substantially parallel to the edge of the bottom and two branches 152, radial or generally oriented towards the central zone so as to delimit the sector 14 on three sides leaving the continuity of the material from the bottom to the central zone 1 1 1. This continuity of the material is shown schematically by a dashed line corresponding to a connecting zone 17 which extends over a certain width in the radial direction.
Plus précisément, la ligne de rupture 15 se compose du segment extérieur 151 longeant à une certaine distance le bord 1 13 du fond et se poursuivant à chaque extrémité par une courte branche 152 laissant subsister la zone de liaison 17 reliant le secteur 14 à la zone centrale 1 1 1 du fond et constituant une zone charnière permettant au secteur 14 d'être détaché du fond 1 1 par la rupture partielle ou totale de sa ligne de rupture 15 pour se soulever par rapport à la surface du fond par l'effet de charnière réalisé par cette zone de liaison 17.  More specifically, the rupture line 15 consists of the outer segment 151 running at a distance from the edge 1 13 of the bottom and continuing at each end by a short branch 152 leaving the connecting zone 17 connecting the sector 14 to the zone central 1 1 1 of the bottom and constituting a hinge zone allowing the sector 14 to be detached from the bottom 1 1 by the partial or total breaking of its breaking line 15 to lift from the surface of the bottom by the effect of hinge made by this connecting zone 17.
La ligne de rupture 15 est formée de préférence par un affaiblissement de la matière au moment de la fabrication de la capsule, par injection-compression, laissant lisse la surface extérieure du fond de sorte que comme indiqué ci-dessus, la ligne de rupture 15 apparaît à l'intérieur de la capsule et non à l'extérieur. Mais la solution inverse n'est pas exclue. La ligne de rupture 15 est simplement une réduction de l'épaisseur de la matière sans traverser l'épaisseur, ni présenter de perçage de façon que le fond 1 1 soit parfaitement étanche comme le res- tant de la capsule. Les secteurs 14 sont séparés par des bandes de liaison 16 reliant le bord 1 13 à la zone centrale 1 1 1 à travers la zone périphérique 1 12 de façon à rigidifier le fond 1 1 pour qu'il ne risque pas de s'enfoncer au contact avec un picot. The rupture line 15 is preferably formed by a weakening of the material at the time of manufacture of the capsule, by injection-compression, leaving the outer surface of the bottom smooth so that, as indicated above, the rupture line 15 appears inside the capsule and not on the outside. But the opposite solution is not excluded. The breaking line 15 is simply a reduction in the thickness of the material without going through the thickness, or having a bore so that the bottom 1 1 is perfectly sealed as the remaining capsule. The sectors 14 are separated by connecting strips 16 connecting the edge 1 13 to the central zone 1 1 1 through the peripheral zone 1 12 so as to stiffen the bottom 1 1 so that it does not risk sinking into the contact with a picot.
Les bandes de liaison 16 sont dans l'alignement radial du gousset médian 21 de chaque groupe de trois goussets. Les secteurs 14 entre les bandes de liaison 16 sont symétriques par rapport à une direction radiale respective passant par un gousset 22 de la couronne tron- conique 124 de sorte que le bord 1 13 du fond est renforcé au-delà du segment extérieur 151 de la ligne de rupture 15. Dans cette disposition, les goussets 22 sont également soutenus par les groupes de goussets 21 de la ceinture tronconique 122.  The connecting strips 16 are in the radial alignment of the middle gusset 21 of each group of three gussets. The sectors 14 between the connecting strips 16 are symmetrical with respect to a respective radial direction passing through a gusset 22 of the truncated ring gear 124 so that the edge 13 of the bottom is reinforced beyond the outer segment 151 of the In this arrangement, the gussets 22 are also supported by the groups of gussets 21 of the frustoconical belt 122.
Les goussets 21 , 22 et les bandes de liaison 16 forment ainsi un réseau d'éléments de renforcement entourant la ligne de rup- ture 15 de chaque secteur 14.  The gussets 21, 22 and the connecting strips 16 thus form an array of reinforcing elements surrounding the break line 15 of each sector 14.
La zone périphérique 1 12 dans laquelle se trouvent les secteurs 14 a une forme bombée.  The peripheral zone 1 12 in which sectors 14 are located has a convex shape.
La zone centrale 1 1 1 se compose d'une couronne 1 1 1a, de forme bombée avec à l'intérieur de celle-ci une couronne plate 1 lb et au centre un dôme 1 1 le en creux.  The central zone 1 1 1 consists of a crown 1 1 1a, domed shape with inside thereof a flat ring 1 lb and in the center a dome 1 1 the hollow.
La forme bombée de la couronne 1 1 1a prolonge la forme bombée de la zone périphérique 1 12.  The curved shape of the crown 1 1 1a extends the curved shape of the peripheral zone 1 12.
En résumé, la succession des formes de révolution 121 , 122, 123, 124 et leurs lignes de jonction 122a, 123a, 124a entre elles et la ligne de jonction formée par le bord 1 13, avec le fond 1 1 ainsi que les renforts intérieurs constitués par les ensembles de goussets 21 , 22 et l'anneau 23 réalisent une partie inférieure de la capsule, y compris le fond, particulièrement rigide pour ne pas se déformer sous la poussée du piston.  In summary, the succession of the forms of revolution 121, 122, 123, 124 and their junction lines 122a, 123a, 124a between them and the junction line formed by the edge 1 13, with the bottom 1 1 and the internal reinforcements constituted by sets of gussets 21, 22 and the ring 23 provide a lower portion of the capsule, including the bottom, particularly rigid not to deform under the thrust of the piston.
II est à souligner que le plan de coupe (II II) passant par les deux secteurs 14 et le segment extérieur 151 des deux lignes de rupture 15 laissent apparaître ses lignes de rupture à la figure 4A.  It should be emphasized that the section plane (II II) passing through the two sectors 14 and the outer segment 151 of the two rupture lines 15 reveal its break lines in FIG. 4A.
Selon la figure 4B la capsule 1 se place dans le logement d'une machine connue en soi, non représentée qui réalise l'étanchéité entre l'amont et l'aval de la capsule selon le sens de passage du liquide, au niveau du rebord 13 et de l'opercule de façon que le liquide injecté soit obligé de traverser la capsule 1 et ne puisse la contourner vers la sortie, côté opercule. Le fond 1 1 de la capsule est exposé à la poussée des picots 31 du piston qui le percent pour injecter du liquide d'extraction dans la cavité de la capsule et ressortir comme boisson par l'opercule ouvert. According to Figure 4B the capsule 1 is placed in the housing of a machine known per se, not shown which provides sealing between the upstream and downstream of the capsule in the direction of passage of the liquid, at the rim 13 and the lid so that the injected liquid is forced through the capsule 1 and can not bypass the exit side operculum. The bottom 1 1 of the capsule is exposed to the thrust of the pins 31 of the piston which pierce it to inject extraction liquid in the cavity of the capsule and out as a drink by the open lid.
Les picots 31 sont répartis sur le piston dans une zone d'action 3 annulaire et notamment sur un cercle centré sur l'axe du piston qui est aussi l'axe XX de la capsule. La zone d'action 3 che- vauche la zone périphérique 1 12 et la couronne bombée 1 1 1a entre le bord 1 13 et la couronne plate 1 1 1b  The pins 31 are distributed over the piston in an annular action zone 3 and in particular on a circle centered on the axis of the piston which is also the axis XX of the capsule. The action zone 3 flips the peripheral zone 1 12 and the curved crown 1 1 1a between the edge 1 13 and the flat crown 1 1 1b
Comme les secteurs périphériques 14 sont de préférence répartis régulièrement autour de l'axe XX et que leur nombre est supérieur à celui des picots, cela évite que tous les picots risquent d'arriver sur des bandes de liaison 16. Il faut en effet que les picots du piston arrivent sur la surface des secteurs 14 ou du moins à la base des secteurs et non sur les bandes de liaison 16.  As the peripheral sectors 14 are preferably regularly distributed around the axis XX and their number is greater than that of the pins, this prevents all the pins from arriving on binding strips 16. It is indeed necessary that the Piston pins arrive on the surface of sectors 14 or at least at the base of the sectors and not on the connecting strips 16.
En général, il y a trois picots 31 régulièrement répartis autour de l'axe du piston de sorte que le fond 1 1 comporte de préfé- rence quatre secteurs 14.  In general, there are three pins 31 regularly distributed around the axis of the piston so that the bottom 1 1 preferably comprises four sectors 14.
Le nombre de secteurs 14 est juste supérieur à celui des picots 31 de préférence d'une unité pour avoir une entrée globale de liquide régulièrement répartie, assurant un bon épuisement du produit contenu dans la capsule. Ainsi, et comme cela apparaît à la figure 4C très schématique, pour cette disposition usuelle des picots 31 , au moins deux secteurs 14 seront complètement ouverts et les deux autres le seront partiellement alors que pour un nombre plus grand de secteurs 14, certains ne seraient pas dans le périmètre d'action des picots 31.  The number of sectors 14 is just greater than that of the pins 31, preferably one unit to have an evenly distributed overall liquid intake, ensuring good exhaustion of the product contained in the capsule. Thus, and as appears in Figure 4C very schematic, for this usual arrangement of the pins 31, at least two sectors 14 will be fully open and the other two will be partially while for a larger number of sectors 14, some would be not within the scope of action of the pins 31.
Comme l'orientation de la capsule 1 autour de son axe XX, dans le logement de la machine n'est pas imposée par la forme puisque la capsule est symétrique en rotation et que son orientation est aléatoire, la distribution et la forme des segments 14 du fond sont conçues pour que :  As the orientation of the capsule 1 about its axis XX, in the housing of the machine is not imposed by the shape since the capsule is symmetrical in rotation and that its orientation is random, the distribution and the shape of the segments 14 from the bottom are designed so that:
- les picots 31 puissent pousser au moins certains secteurs 14 pour ouvrir la ligne de rupture 15 sans déformer le bord 1 13 ; - si un picot 31 arrive sur une bande de liaison 16, celle-ci n'est pas percée par le picot, mais déformée avec une partie de la zone centrale 1 1 1 , ce qui provoque la déchirure au moins locale de la ligne de rupture 15 à proximité mais ne risque pas de déformer la capsule et de la coincer dans le logement de la machine. - The pins 31 can push at least some sectors 14 to open the break line 15 without deforming the edge 1 13; - If a pin 31 arrives on a connecting strip 16, it is not pierced by the pin, but deformed with a portion of the central area 1 1 1, which causes the tear least local of the line of rupture 15 nearby but will not deform the capsule and jam in the housing of the machine.
L'intérieur du fond 1 1 est couvert par une nappe non représentée, formant un filtre mécanique retenant le produit.  The inside of the bottom 1 1 is covered by a not shown sheet, forming a mechanical filter retaining the product.
La figure 4B montre la répartition usuelle des picots 31 du piston. Il s'agit de trois picots 31 situés sur un cercle centré sur l'axe XX. Plus généralement, les picots 31 peuvent avoir une répartition différente, aussi la figure 4B montre-t-elle la surface annulaire constituant la zone d'action 3 des picots. Cette zone chevauche les secteurs 14, leur zone de liaison 17 et la limite géométrique (selon le dessin) entre la zone périphérique 1 12 et la zone centrale 1 1 1.  Figure 4B shows the usual distribution of the pins 31 of the piston. These are three pins 31 located on a circle centered on the axis XX. More generally, the pins 31 may have a different distribution, also Figure 4B shows the annular surface constituting the action zone 3 of the pins. This zone overlaps the sectors 14, their connecting zone 17 and the geometric limit (according to the drawing) between the peripheral zone 1 12 and the central zone 1 1 1.
L'orientation de la capsule 1 par rapport aux picots 21 est aléatoire, aussi tous les secteurs périphériques 14 ne sont-ils pas nécessairement en face de picots 31. Dans l'exemple représenté, le prolongement de la bande de liaison 16 arrive sur un picot de sorte que la surface du fond qui ne peut être percée par le picot à cause de son épaisseur, est déformée et partiellement enfoncée dans la capsule. Cette déformation met en tension les deux branches 152 de part et d'autre de cette bande de liaison 16.  The orientation of the capsule 1 relative to the pins 21 is random, and all the peripheral sectors 14 are not necessarily in front of pins 31. In the example shown, the extension of the connecting strip 16 arrives on a picot so that the bottom surface that can not be pierced by the pin because of its thickness, is deformed and partially embedded in the capsule. This deformation puts in tension the two branches 152 on either side of this connecting strip 16.
La figure 4C montre l'ouverture des secteurs 14 par la poussée des picots 31 contre le fond de la capsule. Les secteurs péri- phériques 14 s'ouvrent différemment suivant l'orientation relative entre le fond 1 1 de la capsule et la position des picots 31.  FIG. 4C shows the opening of the sectors 14 by the thrust of the pins 31 against the bottom of the capsule. The peripheral sectors 14 open differently depending on the relative orientation between the bottom 1 1 of the capsule and the position of the pins 31.
Pour mettre en évidence l'ouverture des secteurs 14, les différentes parties du fond sont ombrées pour laisser en blanc les parties ouvertes des secteurs 14.  To highlight the opening of the sectors 14, the different parts of the bottom are shaded to leave blank the open parts of the sectors 14.
Le mouvement de fermeture de la machine produit l'ouverture de certains secteurs 14 du fond par les picots 21 du piston avant l'injection de fluide extracteur. Les secteurs périphériques 14 fonctionnant comme des sortes d'ouïes, laissant passer le fluide selon différentes veines traversant le produit de la capsule. Cet avantage de répartition des points d'entrée du fluide est d'autant plus marquant que l'ouverture des secteurs est orientée vers le bord 1 13 de la paroi périphérique et non vers le centre, de sorte que le fluide arrive en de multiples points dans la masse de produit, évitant les chemins préférentiels qui traverseraient le produit suivant des lignes de moindre résistance et généraient des pertes de matière non infusée. The closing movement of the machine produces the opening of certain sectors 14 of the bottom by the pins 21 of the piston before the extraction fluid injection. The peripheral sectors 14 functioning as kinds of gills, letting the fluid pass through different veins passing through the product of the capsule. This advantage of distribution of the points of entry of the fluid is even more striking than the opening of the sectors is oriented towards the edge 13 of the peripheral wall and not towards the center, so that the fluid arrives at multiple points in the mass of product, avoiding the preferential paths which would cross the product along lines of less resistance and generated losses of non-infused material.
La capsule 1 décrite ci-dessus est de préférence réalisée en un matériau biodégradable et notamment compostable, choisi dans le groupe de matériaux incluant le PLA (acide polylactique) ou des mélanges de celui-ci et d'autres matériaux biodégradables ou compos- tables. Comme ce matériaux a, dans certains cas, tendance à gonfler si bien que la capsule pourrait se bloquer dans la cavité de la machine, il est avantageux de réduire l'épaisseur de la paroi pour diminuer les dimensions extérieures de la capsule au niveau de la paroi latérale 12. Cela est possible sans risquer que la capsuler ne soit déformée par la poussée du piston de la machine car cette poussée du piston agit pratiquement dans la direction de la partie supérieure tronconique 121 de la paroi 12, soutenue par la cavité de la machine ; cette poussée du piston est reçue par le fond 1 1 et la partie inférieure 121 , 122, 123, 124, renforcée de la capsule de sorte que la poussée est répartie régulièrement.  The capsule 1 described above is preferably made of a biodegradable and in particular compostable material selected from the group of materials including PLA (polylactic acid) or mixtures thereof and other biodegradable or composable materials. As this material has, in some cases, a tendency to swell so that the capsule could lock in the cavity of the machine, it is advantageous to reduce the thickness of the wall to reduce the external dimensions of the capsule at the level of the This is possible without the risk of the capsulator being deformed by the thrust of the piston of the machine because this thrust of the piston acts substantially in the direction of the frustoconical upper portion 121 of the wall 12, supported by the cavity of the machine; this thrust of the piston is received by the bottom 1 1 and the lower portion 121, 122, 123, 124, reinforced with the capsule so that the thrust is evenly distributed.
Cette partie inférieure renforcée peut avoir une paroi d'épaisseur réduite.  This reinforced lower part may have a wall of reduced thickness.
En revanche, le fond est d'épaisseur plus grande car la poussée s'exerce contre la surface du fond 1 1.  On the other hand, the bottom is of greater thickness because the thrust is exerted against the surface of the bottom 1 1.
A titre d'exemple, l'épaisseur de la paroi latérale 12 peut être de l'ordre de 0,50 millimètre et celle du fond, de l'ordre de 0,80 millimètre. La réduction d'épaisseur réalisant la ligne de rupture 15 laissera une épaisseur de matière de l'ordre de 0, 10 millimètre.  For example, the thickness of the side wall 12 may be of the order of 0.50 millimeter and that of the bottom, of the order of 0.80 millimeter. The reduction in thickness forming the rupture line 15 will leave a material thickness of the order of 0.10 millimeters.
Les vues en coupe des figures 5A, 5B selon les plans de coupe (VA, VA) (VB, VB) de la figure 2 montrent la section des goussets 21 (figure 5A) et celle des goussets 22 (figure 5B).  The sectional views of FIGS. 5A, 5B along the section planes (VA, VA) (VB, VB) of FIG. 2 show the section of the gussets 21 (FIG. 5A) and that of the gussets 22 (FIG. 5B).
La figure 6 montre l'empilage de deux capsules 1 , 1 ' ayant un encombrement axial (Ho) et une différence de hauteur (d) entre les deux capsules 1 , 1 '.  Figure 6 shows the stack of two capsules 1, 1 'having an axial size (Ho) and a difference in height (d) between the two capsules 1, 1'.
Dans cet empilage (figure 6), la vue de détail (figure 7A) montre l'appui de la couronne tronconique 124 de la capsule 1 ' sur les appuis 21 1 de la capsule 1. Cet appui permet d'avoir un écart e entre les parois 121 des deux capsules 1 , 1 ' comme le montre la figure 7B. Cette disposition relative permet d'une part d'empiler les capsules vides avec un encombrement réduit au minimum et d'autre part, d'éviter que les capsules ne « collent » les unes aux autres par leur partie tronco- nique 121 et rendent difficile le désempilage automatique pour le remplissage des capsules. In this stack (FIG. 6), the detail view (FIG. 7A) shows the support of the frustoconical crown 124 of the capsule 1 'on the supports 21 1 of the capsule 1. This support allows a gap e between the walls 121 of the two capsules 1, 1 'as shown in Figure 7B. This relative arrangement makes it possible, on the one hand, to stack the empty capsules with a minimum space requirement and, on the other hand, to prevent the capsules from "sticking" to one another by their tronconic portion 121 and make it difficult to automatic destacking for filling the capsules.
