Description

Ensemble de préparation de boisson par extraction d'une capsule  Beverage preparation kit by extraction of a capsule
L'invention concerne en général les machines de préparation de boissons par extraction d'une capsule.  The invention generally relates to machines for preparing drinks by extracting a capsule.
Plus précisément, l'invention concerne selon un premier aspect un dispositif comprenant une machine de préparation de boissons par extraction d'une capsule, la machine comportant :  More specifically, according to a first aspect, the invention relates to a device comprising a machine for the preparation of drinks by extraction of a capsule, the machine comprising:
- une partie fixe ;  - a fixed part;
- une partie mobile par rapport à la partie fixe, entre une position ouverte dans laquelle la capsule peut être chargée dans la machine et une position fermée dans laquelle les parties fixe et mobile maintiennent la capsule dans une position d'extraction dans laquelle la boisson est susceptible d'être préparée par extraction de la capsule ;  a movable part relative to the fixed part, between an open position in which the capsule can be loaded into the machine and a closed position in which the fixed and movable parts hold the capsule in an extraction position in which the beverage is capable of being prepared by extraction of the capsule;
- la partie mobile délimitant un réceptacle dans lequel un corps de la capsule est engagé en position d'extraction, le réceptacle ayant un fond présentant une arrivée de fluide, et une ouverture pour l'engagement du corps à l'opposé du fond.  - The movable portion defining a receptacle in which a body of the capsule is engaged in the extraction position, the receptacle having a bottom having a fluid inlet, and an opening for the engagement of the body opposite the bottom.
Une machine de ce type est connue par exemple de EP 2 103 236. Certaines capsules présentent des zones d'entrée de fluide qui s'ouvrent sous l'effet de la pression du fluide dans le réceptacle. La zone d'entrée est typiquement ménagée sur une portion de fond du corps de la capsule, située en vis-à-vis du fond du réceptacle en position d'extraction.  A machine of this type is known from, for example, EP 2,103,236. Some capsules have fluid inlet zones that open under the effect of fluid pressure in the receptacle. The inlet zone is typically formed on a bottom portion of the body of the capsule, located vis-à-vis the bottom of the receptacle in the extraction position.
II arrive que la zone d'entrée de fluide ne s'ouvre pas, ou s'ouvre mal, du fait de l'écoulement du fluide dans le réceptacle. Le fluide tend à contourner la capsule, ce qui réduit la pression du fluide au niveau de la zone d'entrée et empêche le déchirement correct de la zone d'entrée.  It happens that the fluid inlet zone does not open, or opens badly, due to the flow of fluid in the receptacle. The fluid tends to bypass the capsule, which reduces fluid pressure at the inlet area and prevents proper tearing of the inlet area.
Dans ce contexte, l'invention vise à proposer un dispositif dont le fonctionnement est plus fiable avec de telles capsules.  In this context, the invention aims to provide a device whose operation is more reliable with such capsules.
A cette fin, l'invention porte sur un dispositif du type précité, caractérisé en ce que l'ensemble comprend un adaptateur pourvu d'un élément annulaire interposé entre le fond du réceptacle et le corps de la capsule et entourant l'arrivée de fluide, de manière à créer une étanchéité entre le fond et le corps de la capsule.  To this end, the invention relates to a device of the aforementioned type, characterized in that the assembly comprises an adapter provided with an annular element interposed between the bottom of the receptacle and the body of the capsule and surrounding the fluid inlet. , so as to create a seal between the bottom and the body of the capsule.
Ainsi, l'adaptateur évite que le fluide puisse contourner la capsule, et que la pression sur la zone d'entrée soit diminuée. Quand la capsule est du type à ouverture sous la pression du fluide, l'ouverture de la zone d'entrée se fait de manière plus fiable.  Thus, the adapter prevents the fluid can bypass the capsule, and the pressure on the input area is reduced. When the capsule is of the opening type under fluid pressure, the opening of the inlet zone is more reliably.
Par ailleurs, l'élément annulaire permet de déporter légèrement le corps de la capsule vers l'ouverture, par rapport au fond du réceptacle. Or, il peut exister des défauts de forme au fond du réceptacle, notamment au niveau de la ligne de jonction entre le fond et la paroi latérale du réceptacle. Ces défauts de forme sont par exemple des irrégularités de matière, créant des reliefs le long de cette ligne de jonction. Ces reliefs peuvent provoquer un coincement de la capsule à l'intérieur du réceptacle. Le fait de déporter le corps de la capsule vers l'ouverture réduit le risque que la capsule soit coincée par les défauts de forme. Furthermore, the annular element makes it possible to slightly shift the body of the capsule towards the opening, with respect to the bottom of the receptacle. However, there may be defects in shape at the bottom of the receptacle, particularly at the junction line between the bottom and the side wall of the receptacle. These defects of form are for example irregularities of material, creating reliefs along this line of junction. These reliefs can cause jamming of the capsule inside the receptacle. Deporting the body of the capsule towards the opening reduces the risk that the capsule is stuck by defects in shape.
La machine est typiquement une machine à chargement par gravité, comme connue d'EP 2 103 236. En variante, la machine est à chargement horizontal, ou encore d'un tout autre type.  The machine is typically a gravity loading machine, as known from EP 2 103 236. Alternatively, the machine is horizontal loading, or of any other type.
La partie mobile se déplace entre sa position ouverte et sa position fermée par exemple selon un mouvement sensiblement horizontal, comme décrit par exemple dans EP 2 103 236. En variante, la partie mobile se déplace entre ses positions ouverte et fermée par rapport à la partie fixe selon un mouvement hélicoïdal, ou selon une combinaison de translations et de rotations comme par exemple dans le cas où la partie mobile est liée à la partie fixe par un dispositif à baïonnette.  The moving part moves between its open position and its closed position, for example in a substantially horizontal movement, as described for example in EP 2 103 236. In a variant, the movable part moves between its open and closed positions relative to the part fixed in a helical movement, or in a combination of translations and rotations such as in the case where the movable part is connected to the fixed part by a bayonet device.
L'arrivée de fluide est typiquement au centre du fond. En variante, l'arrivée de fluide est décalée par rapport au centre du fond. En tout état de cause, une fois l'élément annulaire en place entre le fond du réceptacle et le corps de la capsule, l'arrivée de fluide est située au droit de la partie centrale évidée de l'élément annulaire.  The fluid inlet is typically in the center of the bottom. In a variant, the fluid inlet is offset relative to the center of the bottom. In any event, once the annular element in place between the bottom of the receptacle and the body of the capsule, the fluid inlet is located at the right of the hollow central portion of the annular element.
L'élément annulaire entoure complètement l'arrivée de fluide, sur 360 °. Il est à contour fermé.  The annular element completely surrounds the fluid inlet, over 360 °. It is closed contour.
Quand la capsule est en position d'extraction, l'élément annulaire porte d'un côté contre le fond du réceptacle et l'autre côté contre le corps de la capsule.  When the capsule is in the extraction position, the annular element carries on one side against the bottom of the receptacle and the other side against the body of the capsule.
L'élément annulaire se présente par exemple sous la forme d'une rondelle sensiblement plate. Elle est par exemple en une matière plastique ou en caoutchouc ou en un métal mou tel que l'aluminium.  The annular element is for example in the form of a substantially flat washer. It is for example a plastic material or rubber or a soft metal such as aluminum.
Une des grandes faces de l'élément annulaire est tournée vers le fond, et l'autre vers l'ouverture, c'est-à-dire vers le corps de la capsule.  One of the large faces of the annular element is turned towards the bottom, and the other towards the opening, that is to say towards the body of the capsule.
Selon un premier mode de réalisation, l'élément annulaire est fixé au réceptacle. Ainsi, l'adaptateur est rapporté dans le réceptacle. Il reste au fond du réceptacle quand la capsule est évacuée. Le même adaptateur est utilisé pour un grand nombre de capsules. La capsule, une fois chargée dans la partie mobile, vient au contact de l'élément annulaire. Un tel mode de réalisation est particulièrement économique. Un même élément annulaire, simple et d'un coût modéré, permet d'augmenter l'étanchéité pour un grand nombre de capsules.  According to a first embodiment, the annular element is fixed to the receptacle. Thus, the adapter is attached to the receptacle. It remains at the bottom of the receptacle when the capsule is evacuated. The same adapter is used for a large number of capsules. The capsule, once loaded in the movable part, comes into contact with the annular element. Such an embodiment is particularly economical. The same annular element, simple and of moderate cost, makes it possible to increase the tightness for a large number of capsules.
Avantageusement, l'invention comporte un élément de blocage coopérant avec une paroi latérale du réceptacle pour bloquer l'adaptateur en position par rapport à la cavité. Un tel mode de blocage est particulièrement simple et économique. L'adaptateur est engagé en force dans le réceptacle, l'élément de blocage étant interposé entre l'élément annulaire et la paroi latérale. Advantageously, the invention comprises a locking element cooperating with a side wall of the receptacle for locking the adapter in position relative to the cavity. Such a blocking mode is particularly simple and economical. The adapter is engaged in force in the receptacle, the locking element being interposed between the annular element and the side wall.
Typiquement, l'élément de blocage est un jonc élastique solidaire de l'élément annulaire. Par exemple, le jonc élastique est disposé autour de l'élément annulaire. Il est rapporté sur la tranche de l'élément annulaire, et prolonge cet élément annulaire radialement vers l'extérieur.  Typically, the locking element is an elastic ring integral with the annular element. For example, the elastic ring is arranged around the annular element. It is attached to the edge of the annular element, and extends this annular element radially outwardly.
Alternativement, l'élément de blocage comprend un ou plusieurs reliefs, venus de matière avec l'élément annulaire. Typiquement, ces reliefs font saillie radialement vers l'extérieur à partir de l'élément annulaire, de manière à coopérer avec la paroi latérale et bloquer l'adaptateur vis-à-vis de cette paroi. Ces reliefs peuvent avoir toute sorte de forme. Ils sont typiquement répartis régulièrement autour de l'élément annulaire. Ce mode de réalisation de l'élément élastique est particulièrement économique, puisque les reliefs sont fabriqués avec l'élément annulaire.  Alternatively, the locking element comprises one or more reliefs, integral with the annular element. Typically, these reliefs project radially outwardly from the annular element, so as to cooperate with the side wall and block the adapter vis-à-vis the wall. These reliefs can have any kind of shape. They are typically regularly distributed around the annular element. This embodiment of the elastic element is particularly economical, since the reliefs are manufactured with the annular element.
Avantageusement, l'adaptateur comprend un organe de poussée et un ressort de compression liant l'organe de poussée à l'élément annulaire, l'organe de poussée étant en appui contre le corps de la capsule et le ressort étant comprimé entre le fond et le corps quand la capsule est en position d'extraction.  Advantageously, the adapter comprises a thrust member and a compression spring linking the thrust member to the annular element, the thrust member being in abutment against the body of the capsule and the spring being compressed between the bottom and the body when the capsule is in the extraction position.
Ainsi, le ressort tend à pousser la capsule vers l'ouverture, par l'intermédiaire de l'organe de poussée. Quand la partie mobile est déplacée de sa position fermée à sa position ouverte après extraction de la capsule, le ressort et l'organe de poussée permettent d'éjecter la capsule hors du réceptacle. Ceci est particulièrement utile quand des défauts de forme risquent de coincer la capsule dans le réceptacle.  Thus, the spring tends to push the capsule towards the opening, through the thrust member. When the movable portion is moved from its closed position to its open position after extraction of the capsule, the spring and the urging member eject the capsule out of the receptacle. This is particularly useful when defects in shape may jam the capsule in the receptacle.
L'organe de poussée est typiquement une plaque qui prend appui sur la partie de fond de la capsule. Elle est agencée de manière à ne pas obturer la zone d'entrée de fluide de la capsule.  The push member is typically a plate that bears on the bottom portion of the capsule. It is arranged so as not to close the fluid inlet zone of the capsule.
Le ressort est typiquement un ressort hélicoïdal dont une extrémité est solidaire de l'élément annulaire, et l'extrémité opposée solidaire de l'organe de poussée. En variante, le ressort est d'un autre type, et est par exemple ressort à lame, ou tout autre type de ressort.  The spring is typically a helical spring, one end of which is integral with the annular element, and the opposite end integral with the thrust member. Alternatively, the spring is of another type, and is for example leaf spring, or any other type of spring.
Selon un second mode de réalisation, l'élément annulaire est fixé au corps de la capsule et entoure une zone d'entrée agencée pour que le fluide pénètre dans la capsule, lors de l'extraction.  According to a second embodiment, the annular element is fixed to the body of the capsule and surrounds an inlet zone arranged so that the fluid enters the capsule during extraction.
Ce second mode de réalisation, l'élément annulaire est solidaire de la capsule. Il n'est pas solidaire du fond du réceptacle. Ainsi, chaque capsule porte un élément annulaire qui lui est propre. L'élément annulaire vient porter contre le fond du réceptacle quand la capsule est en position d'extraction. Ceci présente l'avantage de renforcer la structure de la capsule, autour de la zone d'entrée, notamment quand celle-ci est prévue pour se rompre sous l'effet de la pression de fluide. Dans ce cas, un sous-ensemble contenant un ressort de compression et un organe de poussoir peut être logé à demeure dans le réceptacle. Ce sous-ensemble est indépendant de l'élément annulaire. This second embodiment, the annular element is integral with the capsule. It is not attached to the bottom of the receptacle. Thus, each capsule carries an annular element of its own. The annular element comes to bear against the bottom of the receptacle when the capsule is in the extraction position. This has the advantage of reinforcing the structure of the capsule around the inlet zone, especially when it is intended to break under the effect of fluid pressure. In this case, a subassembly containing a compression spring and a pusher member can be housed permanently in the receptacle. This subset is independent of the annular element.
Typiquement, l'élément annulaire porté par la capsule est métallique. Il est par exemple en un métal mou tel que l'aluminium. Ceci permet de créer un bon niveau d'étanchéité entre la capsule et le fond de la cavité. Ceci permet également de renforcer de manière efficace la structure de la capsule.  Typically, the annular element carried by the capsule is metallic. It is for example a soft metal such as aluminum. This makes it possible to create a good level of tightness between the capsule and the bottom of the cavity. This also makes it possible to effectively strengthen the structure of the capsule.
Selon un second aspect, l'invention porte sur un ensemble comprenant un dispositif ayant les caractéristiques ci-dessus, et une capsule adaptée pour être insérée dans la machine.  According to a second aspect, the invention relates to an assembly comprising a device having the above characteristics, and a capsule adapted to be inserted into the machine.
Avantageusement, le corps de la capsule comprend une portion de fond disposée en vis-à-vis du fond du réceptacle en position d'extraction, avec une zone d'entrée agencée pour que le fluide pénètre dans la capsule lors de l'extraction, la capsule ayant un renfort métallique annulaire rigidement fixé à la portion de fond autour de la zone d'entrée.  Advantageously, the body of the capsule comprises a bottom portion disposed opposite the bottom of the receptacle in the extraction position, with an inlet zone arranged so that the fluid enters the capsule during extraction, the capsule having an annular metal reinforcement rigidly attached to the bottom portion around the entrance area.
Comme indiqué ci-dessus, ce renfort métallique annulaire fait office d'adaptateur, et permet de créer une étanchéité entre le fond du réceptacle et le corps de la capsule.  As indicated above, this annular metal reinforcement serves as an adapter, and allows to create a seal between the bottom of the receptacle and the body of the capsule.
De préférence, le corps de la capsule comprend une portion de fond disposée en vis-à-vis du fond en position d'extraction, avec un dôme et une zone de moindre résistance entourant le dôme prévue pour se rompre sous l'effet de la pression du fluide dans la cavité, la capsule ayant un renfort métallique sur le dôme. Ceci permet de renforcer la structure de la capsule. Ceci permet également de favoriser l'éjection de la capsule hors du réceptacle, notamment sous l'effet du ressort de compression et de l'organe de poussée de l'adaptateur.  Preferably, the body of the capsule comprises a bottom portion disposed opposite the bottom in the extraction position, with a dome and a zone of weakness surrounding the dome provided to break under the effect of the fluid pressure in the cavity, the capsule having a metal reinforcement on the dome. This reinforces the structure of the capsule. This also promotes the ejection of the capsule out of the receptacle, especially under the effect of the compression spring and the push member of the adapter.
La capsule est par exemple du type décrit dans la demande de brevet déposée sous le numéro PCT/FR 201 1/051343, et décrit comme étant du type avec un dôme à retournement brusque.  The capsule is for example of the type described in the patent application filed under the number PCT / FR 201 1/051343, and described as being of the type with a sudden-turning dome.
Le corps de la capsule présente une forme générale de coupelle, et comprend une paroi périphérique, une portion de fond fermant une extrémité arrière du corps et un rebord annulaire entourant une extrémité avant ouverte du corps. L'extrémité avant est fermée typiquement par un opercule. Comme indiqué ci-dessus, selon une variante de réalisation, la portion de fond comporte une zone d'entrée de fluide prévue pour se déchirer sous l'effet de la pression dans le réceptacle. Selon une autre variante de réalisation, la zone d'entrée est pré-percée. Selon encore une autre variante de réalisation, la zone d'entrée est initialement fermée, la machine comportant des couteaux prévus pour ouvrir la zone d'entrée au moment du chargement de la capsule dans le réceptacle. Dans ce cas, l'élément annulaire de l'adaptateur s'étend autour des couteaux. The body of the capsule has a generally cup-like shape, and includes a peripheral wall, a bottom portion closing a rear end of the body and an annular flange surrounding an open front end of the body. The front end is typically closed by a cover. As indicated above, according to an alternative embodiment, the bottom portion comprises a fluid inlet zone designed to tear under the effect of pressure in the receptacle. According to another embodiment, the entrance zone is pre-drilled. According to yet another variant of realization, the inlet area is initially closed, the machine having knives provided to open the inlet area at the time of loading the capsule into the receptacle. In this case, the annular element of the adapter extends around the knives.
La paroi périphérique est typiquement tronconique ou cylindrique.  The peripheral wall is typically frustoconical or cylindrical.
Le corps est typiquement réalisé d'un seul tenant. La paroi latérale, la portion de fond et le rebord annulaire sont venus de matière. Le corps est réalisé en un matériau étanche à l'air et à l'eau, par exemple dans une matière plastique ou en métal.  The body is typically made in one piece. The side wall, the bottom portion and the annular flange are integral. The body is made of an airtight material and water, for example in a plastic or metal.
Le corps et l'opercule de sortie délimitent ensemble une chambre intérieure contenant une substance (non représentée) pour la préparation d'une boisson.  The body and the outlet cap together define an interior chamber containing a substance (not shown) for the preparation of a beverage.
Avantageusement, la capsule comporte une puce électronique, par exemple de type RFID.  Advantageously, the capsule comprises an electronic chip, for example of the RFID type.
Cette puce est prévue pour stocker des informations concernant la vie de la capsule, (date, heure, lieu de fabrication), le type de produit contenu dans la capsule, sa date de péremption, etc ....  This chip is intended to store information about the life of the capsule (date, time, place of manufacture), the type of product contained in the capsule, its expiry date, etc.
De préférence, la machine comporte un dispositif prévu pour échanger des informations avec la puce électronique.  Preferably, the machine comprises a device provided for exchanging information with the electronic chip.
Par exemple, la machine comporte un organe susceptible de lire les informations contenues dans la puce électronique. Ainsi, la machine peut par exemple vérifier que la capsule n'est pas périmée, ou que la capsule contient un produit correspondant à la boisson souhaitée par l'utilisateur, etc .... Le dispositif peut également ajouter des informations dans la puce électronique par exemple la date et l'heure d'utilisation, ou certains paramètres de fonctionnement de la machine au moment de l'extraction de la capsule.  For example, the machine comprises a member capable of reading the information contained in the electronic chip. Thus, the machine can for example verify that the capsule is not outdated, or that the capsule contains a product corresponding to the drink desired by the user, etc. The device can also add information in the microchip for example the date and time of use, or certain operating parameters of the machine at the time of extraction of the capsule.
La puce électronique peut également envoyer des ordres à la machine, par exemple déclencher le fonctionnement de la machine une fois la capsule en position d'extraction et la puce électronique en position au droit de l'organe de lecture.  The electronic chip can also send commands to the machine, for example triggering the operation of the machine once the capsule in the extraction position and the electronic chip in position to the right of the reading member.
La puce électronique peut également être prévue pour échanger des informations avec toutes sortes de capteurs, qui ne font pas partie de la machine, par exemple avec un téléphone portable.  The microchip may also be provided for exchanging information with all kinds of sensors, which are not part of the machine, for example with a mobile phone.
D'autres caractéristiques et avantages de l'invention ressortiront de la description détaillée qui en est donnée ci-dessous, à titre indicatif et nullement limitatif, en référence aux figures annexées parmi lesquelles :  Other features and advantages of the invention will emerge from the detailed description given below, for information only and in no way limitative, with reference to the appended figures among which:
- la Figure 1 est un schéma de principe d'un ensemble conforme à l'invention, pour un premier mode de réalisation de l'invention ;  - Figure 1 is a block diagram of an assembly according to the invention, for a first embodiment of the invention;
- les Figures 2 et 3 sont des vues en coupe et en élévation de deux variantes de réalisation de l'adaptateur de la Figure 1 ; et - la Figure 4 est une représentation schématique d'une capsule pour un second mode de réalisation de l'invention. Figures 2 and 3 are sectional and elevational views of two alternative embodiments of the adapter of Figure 1; and - Figure 4 is a schematic representation of a capsule for a second embodiment of the invention.
L'ensemble 1 représenté sur la Figure 1 comporte une machine de préparation de boissons par extraction 3, un adaptateur 5 et une capsule 7 prévue pour être chargée dans la machine.  The assembly 1 shown in Figure 1 comprises an extraction beverage preparation machine 3, an adapter 5 and a capsule 7 designed to be loaded into the machine.
La capsule 7 représentée sur la Figure 1 comporte un corps 9 en forme générale de coupelle et un opercule 1 1 de sortie, délimitant ensemble une chambre intérieure contenant la substance (non représentée) destinée à être extraite pour la préparation de la boisson. La capsule contient par exemple du café moulu, du thé, avec éventuellement des additifs.  The capsule 7 shown in Figure 1 comprises a body 9 generally cup-shaped and an outlet cap 1 1, defining together an inner chamber containing the substance (not shown) intended to be extracted for the preparation of the drink. The capsule contains for example ground coffee, tea, with possibly additives.
Le corps 9 présente une paroi périphérique 13 de forme tronconique et d'axe X, une portion de fond 15 fermant une extrémité axiale de la paroi 13 et une face frontale ouverte 17 à l'opposé du fond. La paroi tronconique 9 va en s'évasant de la portion de fond 15 vers la face frontale 17. La capsule comporte également une collerette 19, solidaire de la paroi 9. La collerette 19 s'étend dans le plan de la face frontale 17. Elle entoure la paroi 9 et s'étend radialement vers l'extérieur à partir de cette paroi 9. L'opercule 1 1 est collé sur la collerette. Il ferme la face frontale du corps.  The body 9 has a peripheral wall 13 of frustoconical shape and X axis, a bottom portion 15 closing an axial end of the wall 13 and an open end face 17 away from the bottom. The frustoconical wall 9 goes flaring from the bottom portion 15 to the end face 17. The capsule also has a collar 19 secured to the wall 9. The collar 19 extends in the plane of the end face 17. It surrounds the wall 9 and extends radially outwardly from this wall 9. The lid 1 1 is glued to the collar. He closes the front of the body.
La portion de fond 15 est étanche à l'air et à l'eau et est prévue pour se rompre sous l'effet d'un fluide sous pression. Elle comporte un dôme central 21 en forme de calotte sphérique. Le dôme 21 est à concavité orientée vers l'intérieur de la capsule. Le dôme s'étend transversalement à l'axe X. Le dôme est déformable vers l'intérieur de la capsule sous l'effet du fluide sous pression à l'extérieur de la capsule.  The bottom portion 15 is airtight and watertight and is designed to rupture under the effect of a fluid under pressure. It comprises a central dome 21 shaped spherical cap. The dome 21 is concavity oriented towards the inside of the capsule. The dome extends transversely to the axis X. The dome is deformable towards the inside of the capsule under the effect of the fluid under pressure outside the capsule.
La portion de fond 15 comprend encore une région périphérique 23 annulaire entourant le dôme 21 . Le dôme 21 est disposé en retrait vers l'intérieur de la capsule par rapport à l'extrémité arrière de cette capsule. La région périphérique 23 comprend une portion périphérique 25 annulaire et une portion axiale 27. La portion périphérique 25 entoure la portion axiale 27. La portion axiale 27 est tubulaire et s'étend axialement suivant l'axe X en rentrant vers l'intérieur de la capsule à partir d'un rebord interne de la portion périphérique 25. La portion axiale 27 est sensiblement cylindrique. Le dôme 21 est fixé à l'extrémité axiale de la portion axiale 27 située vers l'intérieur de la capsule.  The bottom portion 15 further comprises an annular peripheral region 23 surrounding the dome 21. The dome 21 is recessed towards the inside of the capsule relative to the rear end of this capsule. The peripheral region 23 comprises an annular peripheral portion 25 and an axial portion 27. The peripheral portion 25 surrounds the axial portion 27. The axial portion 27 is tubular and extends axially along the X axis while returning towards the inside of the capsule from an inner rim of the peripheral portion 25. The axial portion 27 is substantially cylindrical. The dome 21 is attached to the axial end of the axial portion 27 located towards the inside of the capsule.
La portion axiale 27 et le dôme 21 délimitent dans la portion de fond 15 un évidement 29 extérieur ouvert vers l'arrière.  The axial portion 27 and the dome 21 delimit in the bottom portion 15 an outer recess 29 open towards the rear.
La portion de fond 15 comprend une zone de moindre résistance 31 à la périphérie du dôme 21 . La zone de moindre résistance relie la périphérie du dôme 21 à la portion axiale 27. L'épaisseur de matière dans la zone de moindre résistance 31 est inférieure à l'épaisseur de matière dans la portion axiale 27 et dans le dôme 21 . La zone de moindre résistance 31 raccorde un bord périphérique extérieur du dôme 21 à une extrémité axiale du tronçon axial 27. The bottom portion 15 comprises a zone of weakness 31 at the periphery of the dome 21. The zone of least resistance connects the periphery of the dome 21 to the axial portion 27. The thickness of material in the zone of weakness 31 is less than the thickness of material in the axial portion 27 and in the dome 21. The area of least The resistor 31 connects an outer peripheral edge of the dome 21 to an axial end of the axial section 27.
Lorsqu'un fluide sous pression est amené sur la portion de fond 15, le fluide exerce un effort axial sur le dôme 21 . Le dôme 21 résiste en transmettant l'effort axial à la zone de moindre résistance 31 . Celui-ci est sollicité en tension axialement. Par ailleurs, le dôme tend à s'écraser axialement en se dilatant radialement à sa périphérie. Le dôme 21 en s'écrasant sollicite la zone de moindre résistance 31 radialement vers l'extérieur. La zone de moindre résistance 31 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 31 rompt facilement sous une pression contrôlée, créant une zone d'entrée de fluide dans la capsule.  When a fluid under pressure is brought on the bottom portion 15, the fluid exerts an axial force on the dome 21. The dome 21 resists transmitting the axial force to the zone of least resistance 31. It is stressed axially. Moreover, the dome tends to collapse axially by expanding radially at its periphery. Dome 21 crashing solicits the zone of weakness 31 radially outwardly. The zone of least resistance 31 is biased axially in its direction of extension and in shear in its direction of lesser thickness. As a result, the zone of least resistance 31 easily breaks under a controlled pressure, creating a fluid entry zone in the capsule.
Dans un mode de réalisation, le dôme 21 est à action brusque et peut se retourner sous l'effet de la pression du fluide sur la paroi d'entrée 15. Le dôme 21 se retourne brusquement de façon que sa concavité s'inverse sous l'effet du fluide sous pression. Ceci contribue à une bonne ouverture de la zone de moindre résistance.  In one embodiment, the dome 21 is a snap action and can turn back under the effect of the fluid pressure on the inlet wall 15. The dome 21 turns around suddenly so that its concavity reverses under the effect of the fluid under pressure. This contributes to a good opening of the area of least resistance.
Un filtre (non représenté) est logé à l'intérieur de la capsule, sensiblement au niveau de la face frontale 17. Il empêche le produit logé à l'intérieur de la capsule de s'échapper. Il est rigidement fixé à la paroi périphérique 13. Une fois l'opercule 1 1 enlevé, le filtre constitue une zone de sortie de fluide hors de la capsule.  A filter (not shown) is housed inside the capsule, substantially at the front face 17. It prevents the product housed inside the capsule from escaping. It is rigidly fixed to the peripheral wall 13. Once the lid 11 is removed, the filter constitutes a fluid outlet zone outside the capsule.
La machine 1 est du type à chargement et à évacuation gravitaire dans l'exemple représenté sur la Figure 1 . Elle comporte un puits 33 permettant l'introduction de la capsule verticalement dans la machine, selon un mouvement allant du haut vers le bas. Après extraction de la capsule, cette capsule tombe dans un bac de collecte des capsules usées, non représenté. Ce bac est placé en partie basse de la machine. La capsule usagée tombe dans le bac gravitairement.  The machine 1 is of gravity loading and discharge type in the example shown in FIG. 1. It comprises a well 33 allowing the introduction of the capsule vertically in the machine, in a movement from top to bottom. After extraction of the capsule, this capsule falls into a used capsule collecting tray, not shown. This tray is placed at the bottom of the machine. The used capsule falls into the tank gravity.
La machine comporte une partie fixe 35 et une partie mobile 37 par rapport à la partie fixe 35, entre une position ouverte représentée sur la Figure 1 et une position fermée (non représentée). La partie fixe 35 comprend, entre autres, une grille 39 prévue pour laisser passer la boisson préparée par extraction de la capsule. Après passage à travers la grille, la boisson s'écoule dans un récipient placé par l'utilisateur sous la machine. Le canal de circulation de la boisson en aval de la grille n'est pas représenté.  The machine comprises a fixed portion 35 and a movable portion 37 relative to the fixed portion 35, between an open position shown in Figure 1 and a closed position (not shown). The fixed part 35 comprises, inter alia, a grid 39 provided to let the beverage prepared by extraction of the capsule. After passing through the grid, the drink flows into a container placed by the user under the machine. The circulation channel of the beverage downstream of the grid is not shown.
La partie mobile 37, comme visible sur la Figure 1 , délimite intérieurement un réceptacle 41 prévu pour recevoir le corps 9 de la capsule. Le réceptacle est délimité par un fond borgne 43, une paroi latérale 45 solidaire du fond 43, et présente une ouverture 47 à l'opposé du fond. L'ouverture 47 est délimitée par un bord libre de la paroi latérale 45. Le fond 43 présente une ouverture 49 d'arrivée de fluide, débouchant dans le réceptacle 41 . The movable portion 37, as visible in Figure 1, internally delimits a receptacle 41 provided for receiving the body 9 of the capsule. The receptacle is delimited by a blind bottom 43, a side wall 45 integral with the bottom 43, and has an opening 47 opposite the bottom. The opening 47 is delimited by a free edge of the side wall 45. The bottom 43 has a fluid inlet opening 49, opening into the receptacle 41.
La machine comporte par ailleurs des moyens pour alimenter le réceptacle 41 en un fluide tel que de la vapeur d'eau ou de l'eau surchauffée, à travers l'arrivée 49.  The machine further comprises means for feeding the receptacle 41 in a fluid such as water vapor or superheated water, through the inlet 49.
Le réceptacle 41 présente une forme générale sensiblement conjuguée de la forme générale du corps 9 de la capsule.  The receptacle 41 has a generally substantially conjugate shape of the general shape of the body 9 of the capsule.
Dans la position ouverte de la partie mobile 37, la capsule peut être chargée gravitairement dans la machine 3. Dans cette position ouverte, la partie mobile 37 est écartée de la grille 39.  In the open position of the mobile part 37, the capsule can be loaded gravitarily in the machine 3. In this open position, the mobile part 37 is spaced from the grid 39.
Dans la position fermée, les parties fixes et mobiles 35 et 37 maintiennent la capsule 7 dans une position d'extraction dans laquelle une boisson est susceptible d'être préparée par extraction de la capsule. Dans cette position fermée, la partie mobile est décalée vers la grille 39. Le corps 9 de la capsule est engagé dans le réceptacle 41 . La collerette 19 est pincée entre la partie mobile 37 et la partie fixe 35, avec éventuellement interposition de joints d'étanchéité. Ainsi, la partie mobile 37 se déplace de sa position ouverte à sa position fermée selon un mouvement général sensiblement rectiligne, qui la rapproche de la partie fixe 35 et plus précisément de la grille 39.  In the closed position, the fixed and movable parts 35 and 37 hold the capsule 7 in an extraction position in which a beverage can be prepared by extraction of the capsule. In this closed position, the mobile part is shifted towards the grid 39. The body 9 of the capsule is engaged in the receptacle 41. The flange 19 is clamped between the movable portion 37 and the fixed portion 35, possibly with the interposition of seals. Thus, the movable portion 37 moves from its open position to its closed position in a generally rectilinear general movement, which brings it closer to the fixed part 35 and more precisely to the grid 39.
La machine comporte encore un mécanisme permettant de commander le déplacement de la partie mobile 37 entre ses positions ouverte et fermée, non représenté.  The machine further comprises a mechanism for controlling the movement of the movable portion 37 between its open and closed positions, not shown.
L'adaptateur 5, représenté sur la Figure 2, comprend un élément annulaire 51 , plaqué contre le fond 43 du réceptacle, un élément élastique 53 destiné à coopérer avec la paroi latérale 45 du réceptacle pour bloquer l'adaptateur en position dans le réceptacle, un organe de poussée 55 et un ressort de compression 57 liant l'organe de poussée 55 à l'élément annulaire 51 . L'élément annulaire 51 est une rondelle plate délimitant intérieurement un passage 39 circulaire pour le fluide d'extraction. Une première grande face 61 de la rondelle est plaquée contre le fond 43 du réceptacle. Une seconde grande face 63 est tournée vers l'ouverture 47. L'élément élastique 53 est un jonc en une matière tel qu'un élastomère, entourant la rondelle 51 . Le jonc 53 est fixé à la tranche de la rondelle 51 . Le jonc 53 coopère avec la paroi latérale 45 pour bloquer l'adaptateur en position, par exemple par complémentarité de forme.  The adapter 5, shown in FIG. 2, comprises an annular element 51, pressed against the bottom 43 of the receptacle, an elastic element 53 intended to cooperate with the lateral wall 45 of the receptacle to block the adapter in position in the receptacle, a thrust member 55 and a compression spring 57 connecting the thrust member 55 to the annular element 51. The annular element 51 is a flat washer internally defining a circular passage 39 for the extraction fluid. A first large face 61 of the washer is pressed against the bottom 43 of the receptacle. A second large face 63 is turned towards the opening 47. The elastic element 53 is a rod made of a material such as an elastomer, surrounding the washer 51. The rod 53 is fixed to the edge of the washer 51. The rod 53 cooperates with the side wall 45 to lock the adapter in position, for example by complementarity of form.
L'organe de poussée 55 est une plaque, disposée en vis-à-vis du passage 59 et décalé vers l'ouverture 47 par rapport à ce passage. L'organe élastique 57 est un ressort hélicoïdal d'axe Y. L'axe Y est l'axe central de la paroi latérale 45. La plaque 55 est sensiblement perpendiculaire à l'axe Y.  The thrust member 55 is a plate, disposed opposite the passage 59 and offset towards the opening 47 with respect to this passage. The elastic member 57 is a helical spring of Y axis. The Y axis is the central axis of the side wall 45. The plate 55 is substantially perpendicular to the Y axis.
Quand la partie mobile est en position fermée et que la capsule est en position d'extraction, la portion de fond 15 est disposée en vis-à-vis du fond 43. Plus précisément, la portion périphérique annulaire 25 est en appui contre l'élément annulaire 51 , de telle sorte que l'élément annulaire est comprimé entre la portion annulaire 25 et le fond 43. L'élément annulaire 51 créé ainsi une étanchéité entre le fond 43 et la portion annulaire 25 du corps. Dans cette situation, l'arrivée de fluide 49 est située en vis-à-vis du passage 59. De même, l'évidement 29 de la capsule est situé au droit du passage 59. When the movable portion is in the closed position and the capsule is in the extraction position, the bottom portion 15 is disposed opposite the bottom 43. More specifically, the annular peripheral portion 25 bears against the annular element 51, so that the annular element is compressed between the annular portion 25 and the bottom 43. The annular element 51 thus creates a seal between the bottom 43 and the annular portion 25 of the body. In this situation, the fluid inlet 49 is located opposite the passage 59. Likewise, the recess 29 of the capsule is located at the right of the passage 59.
Par ailleurs, l'organe de poussée 55 est en appui contre le dôme 21 , le ressort 55 étant comprimé entre l'organe de poussée 55 et l'élément annulaire 51 .  Furthermore, the thrust member 55 bears against the dome 21, the spring 55 being compressed between the thrust member 55 and the annular element 51.
Il est à noter que la section de l'organe de poussée 55 est inférieur à la section du passage 59, de telle sorte que la circulation du fluide n'est pas empêchée.  It should be noted that the section of the thrust member 55 is smaller than the section of the passage 59, so that the circulation of the fluid is not prevented.
Dans une variante de réalisation représentée sur la figure 3, le jonc élastique est remplacé par des reliefs 64, faisant saillie radialement vers l'extérieur à partir de l'élément annulaire 51 . Les reliefs 64 sont venus de matière avec l'élément 51 . Ils sont régulièrement répartis autour de l'élément 51 .  In an alternative embodiment shown in FIG. 3, the elastic ring is replaced by reliefs 64 protruding radially outwardly from the annular element 51. The reliefs 64 are integral with the element 51. They are regularly distributed around the element 51.
Le fonctionnement de l'ensemble décrit ci-dessus va maintenant être détaillé. A l'état initial, la partie mobile 37 de la machine est en position ouverte.  The operation of the assembly described above will now be detailed. In the initial state, the mobile part 37 of the machine is in the open position.
Pour préparer une boisson, l'utilisateur retire d'abord l'opercule 1 1 , de manière à libérer la zone de sortie de la capsule. Puis, il introduit la capsule 7 dans le puits de chargement 33 de la machine. La collerette 19 de la capsule est guidée par des glissières (non représentées) ménagées dans le puits de chargement. Les glissières comportent des reliefs, qui arrêtent le mouvement de la capsule et bloquent cette capsule dans une position intermédiaire représentée sur la Figure 1 .  To prepare a drink, the user first removes the lid 1 1, so as to release the outlet area of the capsule. Then he introduces the capsule 7 into the loading well 33 of the machine. The flange 19 of the capsule is guided by slides (not shown) formed in the loading well. The slides include reliefs, which stop the movement of the capsule and block this capsule in an intermediate position shown in Figure 1.
Dans cette position, la capsule 7 se trouve sensiblement au niveau de la partie mobile 37, suivant la direction verticale. La face frontale 17 est tournée vers la grille 39, et la portion de front 15 est tournée vers l'ouverture 47 de la partie mobile.  In this position, the capsule 7 is substantially at the mobile portion 37, in the vertical direction. The end face 17 is turned towards the grid 39, and the front portion 15 is turned towards the opening 47 of the movable part.
Puis, l'utilisateur actionne le mécanisme permettant de déplacer la partie mobile Then, the user actuates the mechanism for moving the moving part
37 de sa position ouverte à sa position fermée. Au cours du déplacement de la partie mobile, le corps 9 de la capsule pénètre dans le réceptacle 41 . Une fois en position d'extraction, la portion de fond 15 de la capsule, et plus précisément la portion annulaire 25, est en appui contre l'élément annulaire 51 de l'adaptateur. Celui-ci créé une étanchéité vis-à-vis du fluide entre le fond du réceptacle et le corps de la capsule. 37 from its open position to its closed position. During the displacement of the moving part, the body 9 of the capsule enters the receptacle 41. Once in the extraction position, the bottom portion 15 of the capsule, and more precisely the annular portion 25 is in abutment against the annular element 51 of the adapter. This creates a tightness vis-à-vis the fluid between the bottom of the receptacle and the body of the capsule.
Puis, l'utilisateur déclenche la pompe de la machine de telle sorte que le fluide alimente le réceptacle 41 via l'arrivée de fluide 49. Du fait de la présence de l'élément annulaire, le fluide ne contourne pas la capsule en passant entre la portion annulaire 25 et le fond 43. Au contraire, il est concentré sur le dôme, et provoque le retournement brusque du dôme et la rupture de la ligne de moindre résistance 31 . Le fluide circule alors de la zone d'entrée de la capsule, à travers le produit jusqu'au filtre et de là à travers la grille 39. La boisson s'écoule dans la tasse de l'utilisateur. Then, the user triggers the pump of the machine so that the fluid feeds the receptacle 41 via the fluid inlet 49. Due to the presence of the annular element, the fluid does not bypass the capsule passing between the annular portion 25 and the bottom 43. On the contrary, it is concentrated on the dome, and causes the abrupt reversal of the dome and the breaking of the line of least resistance 31. The fluid then circulates from the inlet zone of the capsule, through the product to the filter and from there through the grid 39. The drink flows into the user's cup.
Une fois la préparation de la boisson terminée, l'utilisateur déplace la partie mobile de la position fermée à la position ouverte. La capsule est alors projetée en dehors du réceptacle par l'organe de poussée 55 et le ressort de compression 57. Elle tombe dans le bac de collecte prévu à cet effet, de manière gravitaire.  Once the preparation of the drink is complete, the user moves the moving part from the closed position to the open position. The capsule is then projected outside the receptacle by the thrust member 55 and the compression spring 57. It falls into the collection tray provided for this purpose, in a gravity manner.
Un second mode de réalisation de l'invention va maintenant être détaillé, en référence à la Figure 4. Seuls les points par lesquels ce second mode de réalisation diffère du premier seront détaillés ci-dessous.  A second embodiment of the invention will now be detailed with reference to Figure 4. Only the points by which this second embodiment differs from the first will be detailed below.
Les éléments identiques ou assurant les mêmes fonctions dans les deux modes de réalisation seront désignés par les mêmes références.  Identical elements or providing the same functions in the two embodiments will be designated by the same references.
La machine et l'adaptateur, dans le second mode de réalisation, sont identiques à la machine et à l'adaptateur du premier mode de réalisation.  The machine and the adapter, in the second embodiment, are identical to the machine and the adapter of the first embodiment.
En revanche, la capsule comporte un renfort métallique annulaire 65 rigidement fixé à la portion de fond 15, autour de la zone d'entrée. Le renfort métallique annulaire 65 est rigidement fixé contre la surface extérieure de la capsule. Plus précisément, le renfort métallique est fixé sur la portion périphérique annulaire 25 et entoure complètement la zone d'entrée du fluide. Ce renfort est une couche mince d'un matériau métallique mou tel que l'aluminium. Le renfort métallique annulaire 65 s'étend sensiblement sur toute la région périphérique annulaire, depuis le bord périphérique de l'évidement 29 jusqu'à la paroi périphérique 9.  On the other hand, the capsule comprises an annular metal reinforcement 65 rigidly fixed to the bottom portion 15, around the entry zone. The annular metal reinforcement 65 is rigidly fixed against the outer surface of the capsule. More specifically, the metal reinforcement is fixed on the annular peripheral portion 25 and completely surrounds the inlet zone of the fluid. This reinforcement is a thin layer of a soft metal material such as aluminum. The annular metal reinforcement 65 extends substantially over the entire annular peripheral region, from the peripheral edge of the recess 29 to the peripheral wall 9.
La capsule comporte encore un renfort métallique 67, placé sur le dôme 21 . Il couvre le sommet du dôme et s'arrête à distance de la ligne de moindre résistance 31 . Comme précédemment, le renfort métallique 67 est une couche mince, d'un matériau métallique mou tel que l'aluminium.  The capsule further comprises a metal reinforcement 67 placed on the dome 21. It covers the top of the dome and stops at a distance from the line of least resistance. As before, the metal reinforcement 67 is a thin layer of a soft metal material such as aluminum.
Les renforts 65 et 67 sont prévus pour renforcer la structure de la capsule de telle sorte que celle-ci ne s'affaisse pas sous l'effet de la pression de fluide amenée par l'arrivée 49.  Reinforcements 65 and 67 are provided to reinforce the structure of the capsule so that it does not collapse under the effect of the fluid pressure supplied by the inlet 49.
Dans une variante de réalisation, l'ensemble selon le second mode de réalisation ne comporte pas d'élément annulaire 51 . Celui-ci est remplacé par le renfort métallique annulaire 65, qui est plaqué contre le fond 43 du réceptacle et créé ainsi une étanchéité entre le corps de la capsule et le fond du réceptacle.  In an alternative embodiment, the assembly according to the second embodiment has no annular element 51. This is replaced by the annular metal reinforcement 65, which is pressed against the bottom 43 of the receptacle and thus creates a seal between the body of the capsule and the bottom of the receptacle.
Selon une autre variante de réalisation représentée sur la Figure 4, la capsule comporte une puce RFID 69. La puce RFID est montée par exemple sur la paroi périphérique 13 de la capsule. Dans ce cas, la machine comporte un dispositif de lecture 71 , prévu pour échanger des informations avec la puce RFID 69. Le dispositif 71 est agencé de manière à pouvoir communiquer avec la puce RFID 69 quand la capsule est en position d'extraction et la partie mobile de la machine en position fermée. According to another embodiment shown in Figure 4, the capsule comprises an RFID chip 69. The RFID chip is mounted for example on the peripheral wall 13 of the capsule. In this case, the machine comprises a reading device 71, intended to exchange information with the RFID chip 69. The device 71 is arranged to be able to communicate with the RFID chip 69 when the capsule is in the extraction position and the moving part of the machine in the closed position.
La puce RFID 69 est prévue pour assurer la traçabilité de la capsule. Elle comporte des informations telles que le lieu, la date et l'heure de fabrication de la capsule, les principaux événements de la vie de la capsule (date de livraison, durée de stockage, etc ...), le type de produit stocké dans la capsule, la date de péremption, etc ....  The RFID chip 69 is provided to ensure the traceability of the capsule. It includes information such as the place, date and time of manufacture of the capsule, the main events of the life of the capsule (delivery date, storage duration, etc ...), the type of product stored in the capsule, the expiry date, etc.
Le dispositif de lecture 71 est prévu pour lire les informations stockées dans la puce RFID. Il vérifie par exemple que le type de produit stocké dans la capsule correspond bien au type de boisson que l'utilisateur veut préparer. Il peut également contrôler que la date de péremption de la capsule n'est pas dépassée, ou encore régler les paramètres de fonctionnement de la machine en fonction du produit contenu dans la capsule.  The reading device 71 is provided to read the information stored in the RFID chip. It checks for example that the type of product stored in the capsule corresponds to the type of drink that the user wants to prepare. It can also check that the expiry date of the capsule is not exceeded, or adjust the operating parameters of the machine according to the product contained in the capsule.
Inversement, la puce RFID peut également provoquer l'injection de fluide dans le réceptacle.  Conversely, the RFID chip may also cause fluid injection into the receptacle.
