  • the Figure 4 is a front view of an outlet wall according to another variant; and
  • the Figure 5 is a sectional view of an extraction device in which is inserted the capsule of the Figure 1 .

La capsule 2 illustrée sur la Figure 1 est propre à permettre l'extraction d'une boisson sous pression. La capsule 2 est propre à contenir une substance alimentaire à extraire sous pressions.The capsule 2 illustrated on the Figure 1 is suitable to allow the extraction of a drink under pressure. The capsule 2 is able to contain a food substance to extract under pressure.

La capsule 2 comprend une paroi latérale 6 s'étendant suivant un axe longitudinal X-X, une paroi d'entrée 8 fermant une première extrémité arrière de la paroi latérale 6, et une paroi de sortie 10 fermant une deuxième extrémité avant de la paroi latérale 6.The capsule 2 comprises a side wall 6 extending along a longitudinal axis XX, an inlet wall 8 closing a first rear end of the side wall 6, and an outlet wall 10 closing a second front end of the side wall 6 .

La capsule 2 comprend un rebord 12 annulaire entourant l'extrémité avant de la paroi latérale 6 et s'étendant radialement vers l'extérieur à partir de la paroi latérale 6.The capsule 2 comprises an annular flange 12 surrounding the front end of the side wall 6 and extending radially outwardly from the side wall 6.

La paroi latérale 6, la paroi d'entrée 8 et la paroi de sortie 10 délimitent ensemble une chambre 14 de réception d'une substance alimentaire pour l'extraction d'une boisson, par exemple du café. La substance présente dans la capsule 2 n'est pas représentée sur les dessins pour des raisons de clarté.The side wall 6, the inlet wall 8 and the outlet wall 10 together define a chamber 14 for receiving a food substance for extracting a beverage, for example coffee. The substance present in the capsule 2 is not shown in the drawings for the sake of clarity.

La paroi d'entrée 8 est propre à permettre l'entrée d'un liquide d'extraction sous pression, de préférence de l'eau, et la paroi de sortie 10 est propre à permettre la sortie du liquide d'extraction après passage au travers de la substance contenue dans la capsule 2.The inlet wall 8 is adapted to allow the entry of a pressurized extraction liquid, preferably water, and the outlet wall 10 is adapted to allow the exit extraction liquid after passage through the substance contained in the capsule 2.

La paroi latérale 6 et la paroi d'entrée 8 sont venues de matière. Elles définissent un corps réalisé d'un seul tenant en forme de coupelle. La paroi latérale 6 et la paroi d'entrée 8 sont par exemple moulées par injection de matière plastique.The side wall 6 and the inlet wall 8 are integral. They define a body made in one piece in the form of a cup. The side wall 6 and the inlet wall 8 are for example molded by plastic injection.

La paroi latérale 6 est sensiblement tronconique de révolution autour de l'axe longitudinal X-X. La paroi latérale 6 s'évase de son extrémité arrière vers son extrémité avant. La paroi latérale 6 est rigide.The side wall 6 is substantially frustoconical of revolution about the longitudinal axis X-X. The side wall 6 flares from its rear end to its front end. The side wall 6 is rigid.

La paroi d'entrée 8 est étanche à l'air et à l'eau et est prévue pour se rompre sous l'effet d'un fluide sous pression à l'extérieur de la capsule 2.The inlet wall 8 is airtight and watertight and is designed to rupture under the effect of a fluid under pressure outside the capsule 2.

La paroi d'entrée 8 comprend un dôme 16 central en forme de calotte sphérique. Le dôme 16 est à concavité orientée vers l'intérieur de la capsule 2. Le dôme s'étend transversalement à l'axe X-X. Le dôme 16 est déformable vers l'intérieur de la capsule 2 sous l'effet du fluide sous pression à l'extérieur de la capsule 2.The inlet wall 8 comprises a central dome 16 shaped spherical cap. The dome 16 is concavity oriented towards the inside of the capsule 2. The dome extends transversely to the axis X-X. The dome 16 is deformable towards the inside of the capsule 2 under the effect of the fluid under pressure outside the capsule 2.

La paroi d'entrée 8 comprend une région périphérique 18 annulaire entourant le dôme 16. Le dôme 16 est disposé en retrait vers l'intérieur de la capsule 2 par rapport à l'extrémité arrière de la capsule 2. La région périphérique 18 comprend une portion périphérique 20 annulaire et une portion axiale 22. La portion périphérique 20 entoure la portion axiale 20. La portion axiale 22 est tubulaire et s'étend axialement suivant l'axe X-X en rentrant vers l'intérieur de la capsule 2 à partir d'un bord interne de la portion périphérique 20. La portion axiale 22 est tronconique convergeant vers l'intérieur de la capsule 2. Le dôme 16 est fixé à l'extrémité axiale de la portion axiale 22 située vers l'intérieur de la capsule 2, adjacent à la paroi de sortie 10.The inlet wall 8 comprises an annular peripheral region 18 surrounding the dome 16. The dome 16 is set back towards the inside of the capsule 2 with respect to the rear end of the capsule 2. The peripheral region 18 comprises a annular peripheral portion 20 and an axial portion 22. The peripheral portion 20 surrounds the axial portion 20. The axial portion 22 is tubular and extends axially along the axis XX while returning towards the inside of the capsule 2 from an inner edge of the peripheral portion 20. The axial portion 22 is frustoconical converging towards the inside of the capsule 2. The dome 16 is attached to the axial end of the axial portion 22 located towards the inside of the capsule 2, adjacent to the outlet wall 10.

La portion axiale 22 et le dôme 16 délimitent dans la paroi d'entrée 8 un évidement 24 extérieur ouvert vers l'arrière et dont le fond est formé par le dôme 16 et la surface latérale par la portion axiale 22.The axial portion 22 and the dome 16 delimit in the inlet wall 8 an open recess 24 open towards the rear and whose bottom is formed by the dome 16 and the lateral surface by the axial portion 22.

La paroi d'entrée 8 comprend une zone de moindre résistance 26 à la périphérie du dôme 16. La zone de moindre résistance 26 relie la périphérie du dôme 16 à la région périphérique 18, plus précisément à la portion tubulaire 20.The inlet wall 8 comprises a zone of weakness 26 at the periphery of the dome 16. The zone of weakness 26 connects the periphery of the dome 16 to the peripheral region 18, more precisely to the tubular portion 20.

La zone de moindre résistance 26 est tubulaire et s'étend axialement suivant l'axe X-X. La zone de moindre résistance 26 se présente sous la forme d'une bande dont l'épaisseur, prise radialement à l'axe X-X, est inférieure à celle de la portion axiale 22. L'épaisseur de la zone de moindre résistance 26 est également inférieure à l'épaisseur du dôme 16. La zone de moindre résistance 26 prolonge axialement la portion axiale 22 et se raccorde à la périphérie du dôme 16.The zone of weakness 26 is tubular and extends axially along the axis XX. The zone of least resistance 26 is in the form of a strip whose thickness, taken radially at the axis XX, is smaller than that of the axial portion 22. The thickness of the zone of least resistance 26 is also less than the thickness of the dome 16. The zone of least resistance 26 extends axially the axial portion 22 and is connected to the periphery of the dome 16.

Lorsqu'un fluide sous pression est amené sur la paroi d'entrée 8, le fluide exerce un effort axial sur le dôme 16. Le dôme 16 résiste en transmet l'effort axial à la zone de moindre résistance 26 qui est sollicitée en tension axialement comme illustré par les flèches F1 sur la Figure 1. Le dôme 16 tend à s'écraser axialement en se dilatant radialement à sa périphérie. Le dôme 16 en s'écrasant sollicite la zone de moindre résistance 26 radialement vers l'extérieur comme illustré par les flèches F2 sur la Figure 1. La zone de moindre résistance 26 est sollicitée axialement dans sa direction d'extension et en cisaillement dans sa direction de moindre épaisseur. Il en résulte que la zone de moindre résistance 26 rompt facilement sous une pression contrôlée.When a pressurized fluid is fed to the inlet wall 8, the fluid exerts an axial force on the dome 16. The dome 16 resists transmits the axial force to the zone of weakness 26 which is stressed axially as illustrated by the arrows F1 on the Figure 1 . The dome 16 tends to collapse axially by expanding radially at its periphery. The dome 16 crashing solicits the zone of weakness 26 radially outwards as illustrated by the arrows F2 on the Figure 1 . The zone of least resistance 26 is biased axially in its direction of extension and shear in its direction of lesser thickness. As a result, the zone of least resistance 26 easily breaks under controlled pressure.

Dans un mode de réalisation, le dôme 16 est à action brusque et peut se retourner sous l'effet de la pression d'un fluide sur la paroi d'entrée 8. Le dôme 16 se retourne brusquement de façon que sa concavité s'inverse sous l'effet du fluide sous pression comme illustré en pointillés sur la Figure 1. Lorsqu'un fluide sous pression est amené sur la paroi d'entrée 8, le fluide exerce un effort sur le dôme 16. Le dôme 16 résiste jusqu'à une pression déterminée du fluide et peut se retourner brusquement de sorte que sa concavité s'inverse. En cas de retournement, le dôme 16 et la zone de moindre résistance 26 subissent des déformations importantes qui provoquent des ruptures dans le dôme 16 et/ou ou dans la zone de moindre résistance 26. Les ruptures provoquées sont suffisantes pour laisser entrer l'eau de préparation de la boisson dans la capsule. La pression de retournement du dôme 16 peut être calibrée facilement ce qui permet de contrôler avec précision la pression d'entrée de l'eau et par conséquent la qualité d'extraction de la substance contenue dans la capsule 2.In one embodiment, the dome 16 is a snap action and can turn under the effect of the pressure of a fluid on the inlet wall 8. The dome 16 turns sharply so that its concavity is reversed under the effect of the fluid under pressure as illustrated in dashed lines on the Figure 1 . When a pressurized fluid is fed to the inlet wall 8, the fluid exerts a force on the dome 16. The dome 16 withstands a specific pressure of the fluid and can turn around suddenly so that its concavity reverse. In the event of a reversal, the dome 16 and the zone of least resistance 26 undergo significant deformations which cause breaks in the dome 16 and / or in the zone of least resistance 26. The breaks caused are sufficient to let the water in. of preparation of the drink in the capsule. The reversal pressure of the dome 16 can be calibrated easily which allows to control accurately the water inlet pressure and therefore the quality of extraction of the substance contained in the capsule 2.

La portion tubulaire 20 rentrante rigidifie la région périphérique 18 de la paroi d'entrée 8 ce qui permet de concentrer les déformations dans le dôme 16 et la zone de moindre résistance 26.The reentrant tubular portion 20 stiffens the peripheral region 18 of the inlet wall 8, which makes it possible to concentrate the deformations in the dome 16 and the zone of weakness 26.

La paroi de sortie 10 est rapportée sur le corps 4. La paroi de sortie 10 et la surface interne 28 de la paroi latérale 6 comprennent des reliefs complémentaires d'encliquetage permettant d'encliqueter la paroi de sortie 10 dans l'extrémité avant de la paroi latérale 8.The outlet wall 10 is attached to the body 4. The outlet wall 10 and the inner surface 28 of the side wall 6 comprise complementary snap-in reliefs for snapping the outlet wall 10 into the front end of the outlet. side wall 8.

Comme illustré sur les Figures 1 et 2, la paroi de sortie 10 est de forme discoïdale. La paroi de sortie 10 comprend un cadre 30 périphérique et un filtre 32 s'étendant en travers du cadre 30 et comprenant des orifices 34 pour le passage de l'eau.As illustrated on Figures 1 and 2 the outlet wall 10 is of disc shape. The outlet wall 10 includes a peripheral frame 30 and a filter 32 extending across the frame 30 and including orifices 34 for the passage of water.

Le reliefs d'encliquetage comprennent une nervure de fixation 36 annulaire et une gorge de fixation 38 annulaire complémentaires, prévue l'une sur le paroi latérale 6 et l'autre sur le cadre 30. La nervure de fixation 36 est prévue pour s'encliqueter dans la gorge de fixation 38. La nervure de fixation 36 est ménagée sur la tranche 40 du cadre et la gorge de fixation 38 est ménagée dans la surface interne 28 de la paroi latérale 6.The detent reliefs comprise an annular fixing rib 36 and a complementary annular fixing groove 38, provided on the side wall 6 and the other on the frame 30. The fastening rib 36 is designed to engage with each other. in the fixing groove 38. The fixing rib 36 is formed on the edge 40 of the frame and the fixing groove 38 is formed in the inner surface 28 of the side wall 6.

Le cadre 30 est autoportant de façon à conserver sa forme et assurer l'encliquetage de la paroi de sortie 10 dans la paroi latérale 6. Le cadre 30 fait saillie vers l'avant par rapport à l'extrémité avant du corps 4 et notamment par rapport au rebord 12. Ainsi, le cadre 30 peut venir en appui contre un support d'un dispositif d'extraction.The frame 30 is self-supporting so as to retain its shape and ensure the latching of the outlet wall 10 in the side wall 6. The frame 30 projects forwardly with respect to the front end of the body 4 and in particular by 12. Thus, the frame 30 can bear against a support of an extraction device.

Le cadre 30 est plus épais que le filtre 32. Le filtre 32 est ainsi disposé en retrait vers l'intérieur de la capsule 2 par rapport à la face externe 30A avant du cadre 30 tournée vers l'extérieur de la capsule 2. Ceci évite que le filtre 32 se déchire contre des reliefs d'un support d'un dispositif d'extraction propre à recevoir la capsule 2.The frame 30 is thicker than the filter 32. The filter 32 is thus set back towards the inside of the capsule 2 with respect to the external face 30A before the frame 30 turned towards the outside of the capsule 2. This avoids that the filter 32 tears against reliefs of a support of an extraction device adapted to receive the capsule 2.

Les orifices 34 sont suffisamment petits pour retenir la substance, suffisamment nombreux pour laisser passer la boisson préparée, et de préférence répartis sur la surface du filtre 32 pour assurer une extraction correcte de la substance.The orifices 34 are sufficiently small to retain the substance, sufficiently numerous to let the beverage prepared, and preferably distributed over the surface of the filter 32 to ensure a correct extraction of the substance.

Comme représenté sur la Figure 1, le cadre 30 et le filtre 32 sont venus de matière. Ils sont par exemple réalisés en matière plastique moulée par injection.As shown on the Figure 1 the frame 30 and the filter 32 are integral. They are for example made of plastic injection molded.

Dans une variante illustrée sur la Figure 3, le cadre 30 est rapporté sur le filtre 32. Le cadre 30 est par exemple surmoulé sur le filtre 32, de préférence sur la région marginale du filtre 32. La région marginale du filtre 32 est noyée dans l'épaisseur du cadre 30.In an illustrated variant on the Figure 3 , the frame 30 is attached to the filter 32. The frame 30 is for example overmolded on the filter 32, preferably on the marginal region of the filter 32. The marginal region of the filter 32 is embedded in the thickness of the frame 30.

Le filtre 32 est formé par exemple d'un filtre, d'un film percé ou d'un tissu. Le filtre 32 est réalisé en matière plastique, en fibres naturelles, synthétiques ou métallique ouen métal. Le filtre 32 est par exemple un film en aluminium percé.The filter 32 is formed for example of a filter, a pierced film or a fabric. The filter 32 is made of plastic, natural fibers, synthetic or metal or metal. The filter 32 is for example a perforated aluminum film.

Le cadre 30 est par exemple en matière plastique injectée sous pression. Une matière plastique formant le cadre 30 est par exemple différente d'une matière plastique formant le filtre 32. Le cadre 30 est réalisé dans une matière plastique permettant l'obtention d'un cadre rigide autoportant.The frame 30 is for example of plastic material injected under pressure. A plastic material forming the frame 30 is for example different from a plastic material forming the filter 32. The frame 30 is made of a plastic material for obtaining a rigid self-supporting frame.

Dans une variante illustrée sur la Figure 4, la paroi de sortie 10 comprend des traverses de renfort 41 s'étendant transversalement en travers du cadre 30. Les traverses de renfort 41 sont venues de matière avec le cadre 30. Des traverses de renfort 41 sont prévues sur la face externe du filtre 32 tournée vers l'extérieur de la capsule 2 et/ou la face interne du filtre 32 tournée vers l'intérieur de la capsule 2.In an illustrated variant on the Figure 4 , the outlet wall 10 comprises reinforcing cross-members 41 extending transversely across the frame 30. The reinforcing cross-members 41 are integral with the frame 30. Reinforcing cross-members 41 are provided on the outer face of the filter 32 turned towards the outside of the capsule 2 and / or the internal face of the filter 32 turned towards the inside of the capsule 2.

Comme représentées sur la Figure 4, les traverses de renfort 41 forment une croix. En variante, les traverses de renfort sont agencées différemment.As represented on the Figure 4 , reinforcing cross members 41 form a cross. In a variant, the reinforcing crosspieces are arranged differently.

La paroi de sortie 10 peut être obtenue facilement et à faible coût. Ses orifices 34 calibrés permettent de contrôler la pression de sortie de la boisson. La capsule 2 est fabriquée facilement en remplissant le corps 4 avec la substance puis en fixant la paroi de sortie 10 mécaniquement sur le corps 4 par simple clipsage de la paroi de sortie 10 dans la paroi latérale 8. Cette opération de fixation est simple, fiable et facilement industrialisable à grande échelle. Le clipsage permet de compacter la substance.The outlet wall 10 can be obtained easily and at low cost. Its orifices 34 calibrated to control the outlet pressure of the drink. The capsule 2 is manufactured easily by filling the body 4 with the substance and then fixing the wall of output 10 mechanically on the body 4 by simply clipping the outlet wall 10 in the side wall 8. This fastening operation is simple, reliable and easily industrialized on a large scale. Clipping can compact the substance.

Le rebord 12 est rapporté sur la paroi latérale 6. Le rebord 12 entoure l'extrémité avant ouverte de la paroi latérale 6 du corps 4. Le rebord 12 s'étend radialement vers l'extérieur à partir de la surface externe 42 de la paroi latérale 6. Il ne supporte pas d'élément d'étanchéité rapporté ou de relief d'étanchéité déformable.The flange 12 is attached to the side wall 6.

Le deuxième matériau plastique est par exemple un élastomère thermoplastique (TPE) ou du polyuréthane (PU) qui sont des matériaux peu couteux.Preferably, the flange 12 is made of a second plastic material, different from the first plastic material. The second plastic material is preferably chosen to be a low cost material. The second plastic material is for example a thermoplastic elastomer (TPE) or polyurethane (PU) which are inexpensive materials.

De préférence, les premier et deuxième matériaux plastiques sont des matériaux compatibles, c'est-à-dire des matériaux adaptés pour polymériser l'un avec l'autre. Ainsi, il est possible de produire des capsules 2 à coût réduit. Ces capsules étant destinées à être produites en très grandes séries, cela permet de réaliser des économies importantes.Preferably, the first and second plastic materials are compatible materials, i.e. materials adapted to polymerize with each other. Thus, it is possible to produce capsules 2 at reduced cost. These capsules being intended to be produced in very large series, this allows significant savings.

Le deuxième matériau peut être coloré dans la masse. Ainsi, il est possible de colorer différemment les rebords 10 de capsules 2 contenant différentes substances, de façon à distinguer aisément une capsule 2 contenant une première substance d'une autre capsule 2 contenant une deuxième substance, différente de la première.The second material can be colored in the mass. Thus, it is possible to color differently the rims 10 of capsules 2 containing different substances, so as to easily distinguish a capsule 2 containing a first substance from another capsule 2 containing a second substance, different from the first.

La capsule 2 comprend une membrane 50 d'étanchéité recouvrant la paroi de sortie 10 pour fermer de manière étanche la capsule 2 à l'extrémité avant de la paroi latérale 6. La membrane 50 est fixée sur le rebord 12 sans être fixée sur la paroi de sortie 10.The capsule 2 comprises a sealing membrane 50 covering the outlet wall 10 to seal the capsule 2 at the front end of the wall. 6. The membrane 50 is fixed on the flange 12 without being fixed on the outlet wall 10.

La membrane 50 est pelable de façon à pouvoir être retirée avant usage par un utilisateur. En variante, la membrane 50 est prévue pour se déchirer sous l'effet d'un fluide sous pression. Dans ce cas, elle comprend par exemple des lignes de faiblesse.The membrane 50 is peelable so that it can be removed before use by a user. Alternatively, the membrane 50 is provided to tear under the effect of a fluid under pressure. In this case, it includes, for example, lines of weakness.

La capsule 2 est représentée sur la Figure 5 insérée dans un dispositif 60 d'extraction de boisson. Ce dispositif 60 d'extraction comprend un logement 62 de réception de la capsule 2 et un conduit 64 d'amenée d'eau sous pression débouchant à l'intérieur du logement 62. Le logement 62 présente une forme complémentaire de celle de la capsule 2. Le conduit 64 débouche dans la capsule 2 à proximité de la paroi d'entrée 8. Le logement 62 présente un support 66 contre lequel l'extrémité avant de la capsule 2 est en appui. Le support 66 comprend au moins un orifice 68 d'évacuation de la boisson.The capsule 2 is represented on the Figure 5 inserted into a beverage extraction device 60. This extraction device 60 comprises a housing 62 for receiving the capsule 2 and a conduit 64 for supplying pressurized water opening into the housing 62. The housing 62 has a shape complementary to that of the capsule 2 The conduit 64 opens into the capsule 2 near the inlet wall 8. The housing 62 has a support 66 against which the front end of the capsule 2 is supported. The support 66 comprises at least one orifice 68 for discharging the beverage.

En fonctionnement, la membrane 50 est retirée et la capsule 2 est insérée dans le logement 62. De l'eau est amenée sous pression dans le logement 62. L'eau sous pression exerce une pression sur le dôme 16. Le dôme 16 sollicite en retour la zone de moindre résistance 26 axialement en traction et radialement en cisaillement. La zone de moindre résistance 26 rompt sous l'effet de la pression de l'eau. L'eau traverse la substance contenue dans la capsule, puis ressort par la paroi de sortie 10 au travers du filtre 32.In operation, the membrane 50 is removed and the capsule 2 is inserted into the housing 62. Water is brought under pressure into the housing 62. The pressurized water exerts a pressure on the dome 16. The dome 16 in return the zone of least resistance 26 axially in tension and radially in shear. The zone of least resistance 26 breaks under the effect of the pressure of the water. The water passes through the substance contained in the capsule, then exits through the outlet wall 10 through the filter 32.

Dans le cas d'un dôme à action brusque, le dôme 16 peut se retourner lorsque la pression de retournement du dôme 16 est atteinte et la paroi d'entrée 8 se rompt.In the case of a sudden-action dome, the dome 16 can turn around when the return pressure of the dome 16 is reached and the inlet wall 8 breaks.

Le cadre 30 de la paroi de sortie 10 est en appui sur le support 66 est n'est pas délogé de la paroi latérale 6 sous l'effet de la pression de l'eau. Le filtre 32 est en retrait vers l'intérieur de la capsule 2 par rapport au cadre 30 et ne se déchire par sur le support 66. Il en résulte que les conditions de sortie de la boisson qui dépendent notamment du nombre d'orifices 34 et de leur section, sont maîtrisées.The frame 30 of the outlet wall 10 is supported on the support 66 and is not dislodged from the side wall 6 under the effect of the pressure of the water. The filter 32 is withdrawn towards the inside of the capsule 2 with respect to the frame 30 and does not tear on the support 66. As a result, the conditions of exit of the drink which depend in particular on the number of orifices 34 and of their section, are mastered.

L'invention s'applique aux capsules pour l'extraction de café sous pression et à des capsules pour l'extraction d'autres boissons sous pression, telle que le thé, le chocolat, etc.... Ainsi, l'invention concerne de manière générale une capsule pour l'extraction d'une boisson sous pression.The invention applies to capsules for the extraction of coffee under pressure and to capsules for the extraction of other pressurized beverages, such as tea, chocolate, etc. Thus, the invention concerns generally a capsule for extracting a drink under pressure.
