DESCRIPCIONDESCRIPTION
Un procedimiento, un sistema y un envase para la preparation de una bebida bajo presion de un fluido.A procedure, a system and a container for the preparation of a beverage under pressure of a fluid.
Sector tecnico de la invencionTechnical sector of the invention
La invencion se refiere a un procedimiento y a un sistema para la preparacion por percolation de una bebida, tal como cafe, y a un envase apto para la puesta practica del sistema y el procedimiento.The invention relates to a method and a system for the preparation by percolation of a beverage, such as coffee, and a container suitable for the practical implementation of the system and the procedure.
Antecedentes de la invencionBackground of the invention
Los sistemas conocidos de preparacion de una bebida por percolacion que combinan una capsula que encierra un producto soluble y una maquina con un dispositivo para la extraction del contenido de la capsula, mediante la circulation forzada de un fluido a presion a traves de la capsula, presentan algunos inconvenientes.The known systems of preparation of a percolating beverage that combine a capsule that encloses a soluble product and a machine with a device for extracting the contents of the capsule, by forced circulation of a pressurized fluid through the capsule, have Some inconvenients.
Desde la propuesta como la descrita en el documento de patente FR 2617389, de 1987, han venido presentandose multiples formas de realization que tienen en comun el empleo de una capsula en forma de copela, provista de un reborde circular en su abertura sobre la que se aplica una membrana o lamina de perforable que cierra la copela, que aloja o contiene una dosis de un producto soluble o adecuado para preparar una infusion. Durante la preparacion de la bebida, se encierra la copela en una cavidad o camara de extraccion formada alrededor de la copela aplicandose sobre su reborde anular un elemento de cierre, de forma similar a la copela y que la envuelve, provisto de medios para perforar el fondo de la copela e introducir fluido a presion en la citada cavidad de extraccion. En una forma de realizacion el fluido se ve forzado a penetrar en la copela a traves de su fondo y eso provoca la deformation y posterior perforation de la lamina rompible que cierra la citada copela, permitiendo un flujo de fluido a presion a traves de la copela.From the proposal as described in patent document FR 2617389, of 1987, multiple forms of realization have been presented that have in common the use of a capsule in the form of a cup, provided with a circular flange in its opening on which apply a pierceable membrane or sheet that closes the cup, which houses or contains a dose of a soluble or suitable product to prepare an infusion. During the preparation of the beverage, the cup is enclosed in a cavity or extraction chamber formed around the cup by applying a closing element on its annular flange, similar to the cup and wrapping it, provided with means to pierce the bottom of the cup and introduce pressurized fluid into said extraction cavity. In one embodiment, the fluid is forced to penetrate the cup through its bottom and that causes deformation and subsequent perforation of the breakable sheet that closes said cup, allowing a flow of pressurized fluid through the cup. .
Son numerosas las propuestas que pretenden dar solution a un acoplamiento estanco entre este elemento de cierre y el reborde anular de la capsula. Tal es el caso por ejemplo de las soluciones descritas en los documentos de patente EP 2289820 y EP 2068684.There are numerous proposals that aim to provide a solution for a tight coupling between this closure element and the annular flange of the capsule. Such is the case, for example, of the solutions described in patent documents EP 2289820 and EP 2068684.
Estos sistemas presentan aun ciertos inconvenientes pendientes de resolver. Por ejemplo, mientras que las capsulas son de un solo uso el elemento de cierre que emplea la maquina es siempre el mismo. Esto significa que dicho elemento de cierre, ademas de tener que estar preparado para estar asiduamente en contacto directo con el fluido empleado para la preparacion de la bebida, puede quedar impregnado del contenido originalmente encerrado en la capsula. Y es que a pesar de que algunas capsulas o sistemas incorporan medios para evitar que la extraccion de los medios de perforacion del fondo de la capsula arrastren consigo trazas del producto contenido en las capsulas, no es evitable que trazas de estos productos queden adheridas a los medios de perforacion y por lo tanto sean susceptibles de quedar suspendidos en la camara de elaboration formada alrededor de una nueva capsula durante la preparacion de una nueva bebida.These systems still have certain problems pending resolution. For example, while the capsules are for single use, the closure element used by the machine is always the same. This means that said closing element, in addition to having to be prepared to be in regular contact with the fluid used for the preparation of the beverage, can be impregnated with the content originally enclosed in the capsule. And although some capsules or systems incorporate means to prevent the extraction of the means of perforation from the bottom of the capsule drag with them traces of the product contained in the capsules, it is not avoidable that traces of these products are adhered to the drilling means and therefore are likely to be suspended in the processing chamber formed around a new capsule during the preparation of a new beverage.
Estos medios de perforacion son tambien un inconveniente a la hora de proteger los usuarios contra una mala manipulacion de las maquinas. Es deseable por lo tanto poder prescindir o eliminar de los elementos de cierre cualquier medio para la perforacion de la capsula que, siendo accesibles para el usuario, puedan lastimarlo.These drilling means are also an inconvenience when it comes to protecting the users against a bad manipulation of the machines. It is therefore desirable to be able to dispense with or eliminate from the closure elements any means for perforating the capsule that, being accessible to the user, can harm it.

Otro inconveniente asociado a estos elementos de cierre es su limpieza y mantenimiento. Normalmente de dificil acceso para el usuario, su interior se ensucia y sobre la superficie en contacto con el fluido utilizado para la preparation de la bebida puede depositarse por ejemplo cal cuando se emplea corrientemente agua de la red.Another drawback associated with these closing elements is their cleaning and maintenance. Normally of difficult access for the user, its interior becomes dirty and on the surface in contact with the fluid used for the preparation of the beverage can be deposited for example lime when water is commonly used from the network.
Otro inconveniente es que puedan quedar restos del fluido empleado en la camara de elaboration cuando una bebida ya se ha preparado, que pueden originar goteos indeseados cuando se separa el elemento de cierre de la capsula.Another drawback is that there may be remnants of the fluid used in the brewing chamber when a beverage has already been prepared, which may cause unwanted drips when the closure element of the capsule is separated.
Es un objetivo de la presente invention un procedimiento, un sistema y un dispositivo que resuelvan estos inconvenientes. Tambien es un objetivo de la invencion un envase que, ademas poder contribuir a resolver estos mismos inconvenientes tambien presente ulteriores ventajas respecto de las capsulas conocidas.It is an objective of the present invention a method, a system and a device that solve these inconveniences. It is also an objective of the invention a package that, in addition to being able to contribute to solving these same drawbacks also presents further advantages over known capsules.
En el ambito de las capsulas que contienen dosis de productos empleados para la confection de una bebida por percolation son bastamente conocidas las capsulas que comprenden un cuerpo en forma de copela cuya embocadura superior esta cerrada por una lamina. Si se desea preservar los productos sin necesidad de envasar las capsulas es preciso que el material empleado para la fabricacion de las capsulas y de las mencionadas laminas sea un material barrera, que no permita el paso de humedad y oxigeno.In the field of capsules containing doses of products used for the preparation of a beverage by percolation, capsules comprising a cup-shaped body whose upper mouth is closed by a laminate are widely known. If it is desired to preserve the products without the need to pack the capsules, it is necessary that the material used for the manufacture of the capsules and of the aforementioned sheets be a barrier material, which does not allow the passage of moisture and oxygen.
Las maquinas utilizadas para la preparacion de las bebidas a partir de una capsula estan especialmente disenadas para una capsula con una configuration determinada. Una capsula que no tenga esta configuracion no podra emplearse pues en la maquina. Ademas, las maquinas pueden estar provistas o desprovistas de elementos que intervienen en la preparacion de la bebida, tales como filtros. Esto significa que si la maquina no esta por ejemplo equipada con un filtro, la capsula debera comprender un elemento que desempene esta funcion, y a la inversa.The machines used for the preparation of beverages from a capsule are specially designed for a capsule with a certain configuration. A capsule that does not have this configuration can not be used in the machine. In addition, the machines may be provided or devoid of elements involved in the preparation of the beverage, such as filters. This means that if the machine is not, for example, equipped with a filter, the capsule should comprise an element that performs this function, and vice versa.
Es tambien un objetivo de la invencion un envase versatil, preparado para poderse utilizar en mas de una maquina. Tambien es un objeto de la invencion un envase que no requiera de una manipulation engorrosa para el usuario para la preparacion de la bebida. Por ejemplo, existen capsulas que precisan que un elemento desprendible, tal como una lamina, sea retirada o separada de la capsula para que esta pueda evacuar la bebida que se prepara. Consecuentemente este elemento, desechable, tiene que tirarse a un contenedor o lugar adecuado para no ensuciar los alrededores de la maquina.It is also an objective of the invention a versatile container, prepared to be used in more than one machine. Also an object of the invention is a container that does not require a cumbersome manipulation for the user for the preparation of the beverage. For example, there are capsules that require that a removable element, such as a sheet, be removed or separated from the capsule so that it can evacuate the beverage being prepared. Consequently, this disposable element has to be thrown into a suitable container or place so as not to dirty the surroundings of the machine.
La invencion pretende pues dar a conocer un envase que, ademas de estar preparado para poderse emplear en maquinas que requieran un formato de capsula distinto esto sea posible sin tener que manipular lamina de cierre alguna.The invention thus aims to disclose a package that, in addition to being prepared to be able to be used in machines that require a different capsule format, this is possible without having to handle any closing foil.
Finalmente, la solution debe ser apta para que, de una forma economica, el producto quede preservado del exterior sin necesidad de alojar el envase en un estuche o similar.Finally, the solution must be suitable so that, in an economical way, the product is preserved from the outside without the need to house the container in a case or similar.

In any case, the wall 8 extends below the closure element 3.
De emplearse el envase 1 como ilustran las Figs. 1 y 2, la pared 8 queda ubicada en el lado de salida de la bebida y puede desempenar la funcion de pared de suministro de la bebida que sale de la capsula 2.If container 1 is used as illustrated in Figs. 1 and 2, the wall 8 is located on the outlet side of the beverage and can perform the function of supply wall of the beverage leaving the capsule 2.
De emplearse el envase 1 como ilustra la Figs. 5, la pared 8 queda ubicada en el lado de suministro del fluido empleado para la preparacion de la bebida, tal como agua, y esta destinada a determinar junto con el fondo 4 de la capsula 2 una camara 100 de elaboration de la bebida, que sustituye las camaras actualmente formadas por un elemento de la maquina que se cierra alrededor de las capsulas.If container 1 is used as illustrated in Figs. 5, the wall 8 is located on the supply side of the fluid used for the preparation of the beverage, such as water, and is intended to determine together with the bottom 4 of the capsule 2 a chamber 100 for making the beverage, which It replaces the cameras currently formed by an element of the machine that closes around the capsules.
En los ejemplos, la pared 8 esta dotada de al menos una abertura 9 para el paso de la infusion al exterior del envase 1, en un caso, o del agua al interior de la capsula 2 en el otro caso, durante la eventual preparacion de la bebida sin haberse retirado previamente el adaptador 7 de la capsula 2. La pared 8 tambien esta dotada de unos medios de rotura 10 o perforation del elemento de cierre 3 de la capsula explicados en mayor detalle mas adelante.In the examples, the wall 8 is provided with at least one opening 9 for the infusion passage outside the container 1, in one case, or the water inside the capsule 2 in the other case, during the eventual preparation of the drink without having previously removed the adapter 7 from the capsule 2. The wall 8 is also provided with means of rupture 10 or perforation of the closure element 3 of the capsule explained in greater detail below.
El envase 1 no solo ofrece dos formatos diferentes, con o sin el adaptador 7, que lo hace apto para dos maquinas convencionales distintas, sino que ademas ofrece la posibilidad de poderse emplear disponiendo el envase 1 orientado con la pared 8 en el lado de suministro del fluido utilizado para la preparacion de la bebida y utilizar la camara 100 como camara de elaboracion, desproveyendo a las maquinas de elementos de cierre que desempenen esta funcion, todo elloThe container 1 not only offers two different formats, with or without the adapter 7, which makes it suitable for two different conventional machines, but also offers the possibility of being able to be used by arranging the container 1 oriented with the wall 8 on the supply side of the fluid used for the preparation of the beverage and use chamber 100 as a processing chamber, depriving the machines of closing elements that perform this function, all this

como se ilustra en la Figs. 5 a la que posteriormente se hace referenda.as illustrated in Figs. 5 to which reference is made later.
En los ejemplos, el adaptador 7 esta acoplado a la capsula 2 con capacidad de desplazarse respecto de esta entre al menos dos posiciones, de las que la primera es una posicion de espera (A), mostrada en la Fig. 1, en la que los medios de rotura 10 o perforation dispuestos en la pared 8 del adaptador 7 no danan el elemento de cierre 3 de la capsula; y la segunda es una posicion operativa (B), mostrada en las Figs. 2 y 5, en la que los citados medios de rotura 10 o perforacion rompen o perforan dicho elemento de cierre 3.In the examples, the adapter 7 is coupled to the capsule 2 with the ability to move with respect to it between at least two positions, of which the first is a waiting position (A), shown in Fig. 1, in which the rupture means 10 or perforation arranged in the wall 8 of the adapter 7 do not damage the closure element 3 of the capsule; and the second is an operating position (B), shown in Figs. 2 and 5, wherein said means of breakage 10 or perforation break or pierce said closure element 3.
El adaptador 7 se desplaza respecto de la capsula 2 en la direction que indican las flechas de la Fig. 2. Este desplazamiento habilita la capsula 2 para la evacuation de la infusion independientemente de si esta se preparara utilizandose el envase 1 con o sin el adaptador 7, en el caso de prepararse la bebida empleando una maquina convencional; y para la entrada del agua desde la camara 100, en el caso de prepararse la bebida segun ilustran la Fig. 5.The adapter 7 moves with respect to the capsule 2 in the direction indicated by the arrows in Fig. 2. This displacement enables the capsule 2 for evacuation of the infusion regardless of whether it is prepared using the container 1 with or without the adapter. 7, in the case of preparing the beverage using a conventional machine; and for the entry of water from chamber 100, in the case of preparing the beverage as illustrated in Fig. 5.
Ventajosamente, al ser el elemento de cierre 3 impermeable al oxlgeno, no es preciso que el adaptador 7 quede acoplado a la capsula 2 de una forma perfectamente estanca, ni que el adaptador 7 sea de un material impermeable al oxlgeno. Preferiblemente eso si, el adaptador 7 estara dimensionado para quedar acoplado con ajuste a la capsula 2, de forma que no pueda desprenderse de forma accidental de la capsula 2. Se preve pues que la posicion de espera (A) sea una posicion de pre-ajuste en la que la capsula 2 quede a presion ajustada dentro del adaptador 7. En este sentido, se preve que la capsula 2 y el adaptador 7 esten dotados de medios complementarios para la retention del adaptador 7 en la posicion de espera (A), mediante por ejemplo el alojamiento de un saliente provisto en uno de la capsula 2 o el adaptador 7 en un entrante provisto en el otro de la capsula 2 o el adaptador 7.Advantageously, since the closure element 3 is oxygen impermeable, it is not necessary that the adapter 7 be coupled to the capsule 2 in a perfectly tight manner, nor that the adapter 7 is made of an oxygen impermeable material. Preferably that if, the adapter 7 will be sized to be fitted with adjustment to the capsule 2, so that it cannot accidentally detach from the capsule 2. It is therefore expected that the waiting position (A) is a pre-position adjustment in which the capsule 2 is pressed into the adapter 7. In this sense, it is envisaged that the capsule 2 and the adapter 7 are provided with complementary means for retaining the adapter 7 in the waiting position (A), by for example the housing of a projection provided in one of the capsule 2 or the adapter 7 in a recess provided in the other of the capsule 2 or the adapter 7.
Volviendo a la posicion operativa (B) antes descrita, las Figs. 1 y 2 ilustran como el fondo 4 de la capsula 2 presenta al menos una proyeccion 11 dirigida hacia el elemento de cierre 3 sobre el que se apoya este cuando los medios de rotura 10 o perforacion de la pared de suministro 8 ejercen una presion contra el elemento de cierre 3. En el ejemplo esta proyeccion 11 (tambien mostrada en la Fig. 4a) esta formada por una concavidad 12 (tambien visible en la Fig. 4c) formada en el fondo 4 de la capsula 2, en concreto en su centro.Returning to the operative position (B) described above, Figs. 1 and 2 illustrate how the bottom 4 of the capsule 2 has at least one projection 11 directed towards the closure element 3 on which it rests when the rupture means 10 or perforation of the supply wall 8 exerts a pressure against the closure element 3. In the example this projection 11 (also shown in Fig. 4a) is formed by a concavity 12 (also visible in Fig. 4c) formed on the bottom 4 of the capsule 2, specifically in its center .
La capsula 2 y el adaptador 7 estan especialmente configurados para que pueda producirse este desplazamiento relativo de una forma simple pero efectiva.The capsule 2 and the adapter 7 are specially configured so that this relative displacement can occur in a simple but effective way.
Para ello, el fondo 4 de la capsula 2 comprende una portion anular periferica 4a, de enlace con la pared lateral 13 de la capsula 2; una porcion central 4b con los pasajes 6; y un resalte anular 4c, que se extiende desde la cara inferior del fondo 4 y que delimita la citada porcion central 4b, en cuyo canto inferior 4d esta adherido de forma estanca el elemento de cierre 3.To this end, the bottom 4 of the capsule 2 comprises a peripheral annular portion 4a, of connection with the side wall 13 of the capsule 2; a central portion 4b with passages 6; and an annular shoulder 4c, which extends from the bottom face of the bottom 4 and that delimits the said central portion 4b, in which lower edge 4d the sealing element 3 is bonded tightly.
A su vez, la pared 8 del adaptador 7 comprende una porcion central concava 8b que enlaza con una primera pared lateral 8c que se apoya y resbala por fuera del resalte anular 4c de la capsula 2, resalte anular 4c que sirve de gula para el desplazamiento del adaptador 7 entre sus posiciones de espera (A) y operativas (B).In turn, the wall 8 of the adapter 7 comprises a concave central portion 8b that links with a first side wall 8c that rests and slides outside the annular shoulder 4c of the capsule 2, annular shoulder 4c which serves as a guide for displacement of the adapter 7 between its waiting (A) and operational (B) positions.
El adaptador 7 comprende ademas en conexion con la primera pared lateral 8c una porcion anular de apoyo 8a, configurada para quedar aplicada contra la porcion periferica 4a del fondo de la capsula 2 cuando el adaptador ocupa la posicion operativa (B), que a su vez conecta con una segunda pared lateral 14, configurada para apoyarse con cierta presion y para deslizar sobre la superficie exterior de la pared lateral 13 de la capsula 2.The adapter 7 also comprises in connection with the first side wall 8c an annular support portion 8a, configured to be applied against the peripheral portion 4a of the bottom of the capsule 2 when the adapter occupies the operative position (B), which in turn connects with a second side wall 14, configured to rest with a certain pressure and to slide on the outer surface of the side wall 13 of the capsule 2.

En una forma de realization alternativa, se preve que la pared 8 tenga capacidad de deformarse elasticamente en direction al elemento de cierre 3 y de adoptar al menos dos estados, de los que el primero es un estado de espera en el que los medios de rotura 10 o perforation del adaptador no alcanzan o danan el elemento de cierre 3; y el segundo es un estado operativo en el que los citados medios de rotura 10 o perforation rompen o perforan dicho elemento de cierre 3. La pared de suministro 8 pasa de un estado a otro al ejercerse una presion digital desde el exterior sobre ella, volviendo automaticamente al estado de espera una vez deja de ejercerse esta presion exterior. Naturalmente, en este caso no es preciso que el adaptador 7 tenga capacidad de desplazarse respecto de la capsula 2 como ocurre en el ejemplo de las Figs. 1 y 2.In an alternative embodiment, it is envisioned that the wall 8 has the ability to elastically deform in the direction of the closure element 3 and to adopt at least two states, of which the first is a waiting state in which the breaking means 10 or perforation of the adapter does not reach or damage the closure element 3; and the second is an operational state in which said means of rupture 10 or perforation break or perforate said closure element 3. The supply wall 8 passes from one state to another when a digital pressure is exerted from the outside on it, returning automatically to the waiting state once this external pressure stops exerting. Naturally, in this case it is not necessary for the adapter 7 to be able to move with respect to the capsule 2 as in the example of Figs. 1 and 2.
En cualquier caso los medios de rotura 10 o perforation del elemento de cierre 3 comprenderlan una serie de proyecciones, preferiblemente en punta, que se elevan desde la cara interior de la pared 8.In any case, the rupture means 10 or perforation of the closure element 3 will comprise a series of projections, preferably pointed, that rise from the inner face of the wall 8.
La portion central 8b de esta pared 8 actua de colector de la infusion durante la eventual preparacion de esta con el envase 1 sin retirarse el adaptador 7 y empleando una maquina convencional.The central portion 8b of this wall 8 acts as a collector of the infusion during the eventual preparation thereof with the container 1 without removing the adapter 7 and using a conventional machine.
Alternativamente, el adaptador 7 puede retirarse, desproveyendo al envase 1 de la pared 8. Asl se obtiene un formato diferente que puede ser compatible con otra maquina convencional. Ventajosamente, no es preciso manipular el elemento de cierre 3 ni por el usuario ni por ningun mecanismo de la maquina para habilitar la capsula 2 para evacuar la infusion pues el elemento de cierre 3 puede haberse desgarrado o roto empleando los medios de rotura 10 o perforation del adaptador 7 antes de que este sea retirado de la capsula 2.Alternatively, the adapter 7 can be removed, depriving the container 1 of the wall 8. Thus a different format is obtained that can be compatible with another conventional machine. Advantageously, it is not necessary to manipulate the closure element 3 neither by the user nor by any mechanism of the machine to enable the capsule 2 to evacuate the infusion since the closure element 3 may have been torn or broken using the means of breaking 10 or perforation of adapter 7 before it is removed from capsule 2.
El desplazamiento relativo entre la capsula 2 y el adaptador 7 no necesariamente debe ser realizado manualmente, pues se preve que la propia maquina realice esta funcion cuando se emplea el envase 1 con el adaptador 7 en una maquina convencional, al cerrar la camara de elaboration de la maquina alrededor del envase 1.The relative displacement between the capsule 2 and the adapter 7 does not necessarily have to be done manually, since it is envisaged that the machine itself will perform this function when the container 1 with the adapter 7 is used in a conventional machine, when closing the processing chamber of the machine around the container 1.
La Figs. 5 muestra un sistema para la preparation de una bebida empleando el envase ilustrado en las Figs. 1 a 4. Este sistema toma ventaja de que la pared 8 puede formar con el fondo 4 de la capsula 2 una camara 100 estanca, adecuada para realizar la funcion de camara de elaboration en sustitucion de las camaras que vienen empleando las maquinas convencionales.Figs. 5 shows a system for the preparation of a beverage using the package illustrated in Figs. 1 to 4. This system takes advantage of the fact that the wall 8 can form a sealed chamber 100 with the bottom 4 of the capsule 2, suitable to perform the function of the processing chamber in substitution of the chambers that the conventional machines have been using.
El sistema de la Fig. 5 comprende el envase 1 y un dispositivo 101 para la preparation de la bebida equipado con medios de inyeccion 102 de un fluido a presion en el interior de la camara 100 del envase 1 a traves de la abertura 9 de la pared 8 del citado envase 1, y una placa de extraction 103, del tipo ya conocidas, que perforara la lamina exterior 15 que cierra la embocadura de la capsula 2 cuando esta se aplaste contra la placa de extraction 103 por efecto del aumento de la presion en el interior de la capsula 2.The system of Fig. 5 comprises the container 1 and a device 101 for the preparation of the beverage equipped with injection means 102 of a pressurized fluid inside the chamber 100 of the container 1 through the opening 9 of the wall 8 of said container 1, and an extraction plate 103, of the type already known, that will pierce the outer sheet 15 that closes the mouth of the capsule 2 when it is crushed against the extraction plate 103 due to the increase in pressure inside the capsule 2.
Para proceder a obtener una bebida, se preve segun una forma de realization disponer el envase 1 de la Fig. 1 en un alojamiento del dispositivo 101, eso es con el adaptador 7 en la position de espera (A); accionar unos medios provistos en el dispositivo 101 para asegurar el acople estanco 104 entre la capsula 2 y el adaptador 7, por ejemplo desplazando el adaptador 7 respecto de la capsula 2 en la direction que indican las flechas de la Fig. 2 hasta que el adaptador alcanza la position operativa (B) ilustrada en la Fig. 5, estableciendose comunicacion hidraulica entre la capsula 2 y la camara 100 al romperse el elemento de cierre 3 por la action de los medios de rotura 10 o perforation; e introducir agua a presion en la camaraTo proceed to obtain a beverage, it is provided according to one embodiment to arrange the container 1 of Fig. 1 in a housing of the device 101, that is with the adapter 7 in the waiting position (A); actuate means provided in the device 101 to ensure the tight coupling 104 between the capsule 2 and the adapter 7, for example by moving the adapter 7 with respect to the capsule 2 in the direction indicated by the arrows in Fig. 2 until the adapter it reaches the operating position (B) illustrated in Fig. 5, establishing hydraulic communication between the capsule 2 and the chamber 100 when the closing element 3 is broken by the action of the breaking means 10 or perforation; and introduce pressurized water into the chamber

100 mediante los medios de inyeccion 102. Esta agua se vera forzada a penetrar en la capsula 2 y a atravesarla en contacto con el producto 5 obteniendose una bebida 105 que saldra por las perforaciones de la lamina exterior 15.100 by means of injection 102. This water will be forced to penetrate the capsule 2 and pass through it in contact with the product 5, obtaining a beverage 105 that will flow through the perforations of the outer sheet 15.
Cabe notar que, al proveerse la pared 8 del adaptador 8 con los medios de rotura 10 o perforation del elemento de cierre 3, el dispositivo 101 puede carecer de pinchos o medios similares para perforar el envase 1 o la capsula 2. Esto significa que se elimina otro componente del dispositivo sujeto a contaminarse o que puede causar danos en el usuario por una mala practica.It should be noted that, when the wall 8 of the adapter 8 is provided with the rupture means 10 or perforation of the closure element 3, the device 101 may lack skewers or similar means to pierce the container 1 or the capsule 2. This means that removes another component of the device subject to contamination or that may cause damage to the user due to bad practice.
Observese que el envase 1 se dispone con la pared 8 en el lado de suministro del fluido empleado para la preparacion de la bebida. Con el proposito de evitar el desplazamiento del producto 5 en el interior de la capsula 2 puede ser de interes disponer dentro de la capsula 2 un disco perforado 16 o simular, encajado a presion dentro de la capsula 2 que impida que el producto 5 se acumule sobre la cara interior de la lamina exterior 15 que cierra la embocadura de la capsula 2.Note that the container 1 is arranged with the wall 8 on the supply side of the fluid used for the preparation of the beverage. In order to avoid the displacement of the product 5 inside the capsule 2, it may be of interest to have a perforated disk 16 or simulate inside the capsule 2, snapped inside the capsule 2 that prevents the product 5 from accumulating on the inner face of the outer sheet 15 that closes the mouth of the capsule 2.
Tambien se preve, segun otra forma de realization, que el desplazamiento del adaptador desde la position de espera (A) y operativa (B) pueda ser realizada manualmente por un usuario previamente a colocar el envase 1 en el alojamiento del dispositivo 101.It is also provided, according to another form of realization, that the displacement of the adapter from the standby (A) and operative (B) position can be performed manually by a user prior to placing the container 1 in the housing of the device 101.
En el ejemplo de la Fig. 5, los medios para asegurar el acople estanco 104 entre la capsula 2 y el adaptador 7 comprenden un pisador que apoya sobre la cara exterior de pared anular de apoyo 8a de la pared 8, y ejerce presion sobre esta para aplicarla a presion contra la portion anular periferica 4a de la capsula 2, actuando ambas a modo de brida o junta de estanqueidad para que la camara 100 sea estanca.In the example of Fig. 5, the means for securing the tight fitting 104 between the capsule 2 and the adapter 7 comprise a treadmill that rests on the outer face of the annular supporting wall 8a of the wall 8, and exerts pressure on it. to apply it under pressure against the peripheral annular portion 4a of the capsule 2, both acting as a flange or seal so that the chamber 100 is sealed.
En este caso el pisador presentarla una superficie de apoyo anular, dimensionada en correspondencia con las dimensiones de la pared anular de apoyo 8a del adaptador 7.In this case the treadmill will have an annular support surface, sized in correspondence with the dimensions of the annular support wall 8a of the adapter 7.
Notese que no es imprescindible que el pisador procure una camara estanca que cierre sobre la pared 8 del adaptador 7, ya que esta parte del dispositivo 101 no sera inundada de agua.Note that it is not essential that the treadmill procure a sealed chamber that closes on the wall 8 of the adapter 7, since this part of the device 101 will not be flooded with water.
Como se ha descrito ya anteriormente, disponiendose el adaptador 7 en la posicion operativa (B) se dota al envase 1 entre la capsula 2 y la pared 8 de una camara de elaboration 100 destinada a recibir y a contener un fluido a presion para la preparation de la bebida. A tal efecto, la forma, el material y/o grosor del fondo 4 de la capsula 2 y de la pared 8 del adaptador deben ser los adecuados para soportar en el interior de la camara 100 de elaboracion las presiones de trabajo que emplean los sistemas de bombeo de los dispositivos convencionales, usualmente superiores a 15 bar.As described above, by placing the adapter 7 in the operative position (B) the container 1 is provided between the capsule 2 and the wall 8 of a processing chamber 100 intended to receive and contain a pressurized fluid for the preparation of the drink. For this purpose, the shape, material and / or thickness of the bottom 4 of the capsule 2 and of the wall 8 of the adapter must be adequate to support the working pressures used by the systems inside the processing chamber 100 for pumping conventional devices, usually over 15 bar.
La Fig. 6 ilustra esquematicamente un envase 1’ que representa una alternativa constructiva al envase 1. En este envase 1’, tambien apto para la puesta en practica del procedimiento de la invencion, en la posicion operativa (B) un reborde anular 18 del adaptador 7 quedara aplicado a presion contra la cara enfrentada de un ala 17 o voladizo provisto a tal efecto en la capsula 2. Segun este ejemplo, los medios para asegurar el acople estanco 104 entre la capsula 2 y el adaptador 7 envuelven lateralmente al envase 1 ’ aunque, como se ha dicho anteriormente, no es preciso que procuren una camara estanca alrededor del envase 1’. A modo de ejemplo, el pisador puede comprender una superficie de apoyo anular dimensionada en correspondencia con el reborde anular 18 del adaptador 7 pero estar dotado por ejemplo de aberturas, orificios o ranuras en aquellas parte no destinadas a pisar sobre el adaptador 7. La invention contempla por ejemplo que los medios para asegurar el acople estanco 104 entre la capsula 2 y el adaptador 7 recuerden una jaula, tal y como ilustra esquematicamente la Fig. 9.Fig. 6 schematically illustrates a container 1 'representing a constructive alternative to container 1. In this package 1', also suitable for the implementation of the method of the invention, in the operative position (B) an annular flange 18 of the adapter 7 will be applied under pressure against the facing face of a wing 17 or cantilever provided for this purpose in the capsule 2. According to this example, the means to ensure the tight coupling 104 between the capsule 2 and the adapter 7 laterally wrap the container 1 'although, as stated above, it is not necessary to seek a sealed chamber around the container 1'. By way of example, the treadmill may comprise an annular support surface dimensioned in correspondence with the annular flange 18 of the adapter 7 but be provided, for example, with openings, holes or grooves in those parts not intended to step on the adapter 7. The invention contemplates, for example, that the means for ensuring the tight coupling 104 between the capsule 2 and the adapter 7 remember a cage, as schematically illustrated in Fig. 9.

En el ejemplo de las Figs. 7 a 9 se muestra esquematicamente un sistema analogo al anteriormente descrito pero que emplea un envase 1’’ diferente a los anteriores.In the example of Figs. 7 to 9 schematically shows an analogous system to the one described above but that uses a 1 ’container different from the previous ones.
El envase 1’’ es similar al de la Fig. 6 y combina una capsula 2 con un adaptador 7 pero se diferencia respecto de este ultimo en que el saliente anular 19 del adaptador 7 que recibira el apoyo de los medios para asegurar el acople estanco 104 del dispositivo 101 no es la misma parte del adaptador 7 destinada a cooperar con la capsula 2 para garantizar el acople estanco entre estos.The package 1 '' is similar to that of Fig. 6 and combines a capsule 2 with an adapter 7 but differs from the latter in that the annular projection 19 of the adapter 7 that will receive the support of the means to ensure the tight coupling 104 of the device 101 is not the same part of the adapter 7 intended to cooperate with the capsule 2 to ensure the tight coupling between them.
Las Figs. 10a y 10b muestran una secuencia del procedimiento para la preparation de la bebida mediante el empleo de la capsula 1’’. Mientras la Fig. 10a muestra el envase 1’’ cuando el adaptador adopta la position de espera (A), la Fig. 10b muestra el instante en el que el desplazamiento de los medios para asegurar el acople estanco 104 del dispositivo 101 en direction al envase 1’’ topan con el saliente anular 19 del adaptador y arrastran este en la direction que indica la flecha de la Fig. 10b hasta que el canto 20 del adaptador 7 queda aplicado a presion contra el ala 17 o voladizo provisto en la capsula 2, adoptando entonces el adaptador la posicion operativa (B). Simultaneamente, los medios de inyeccion 102 se acoplan de forma estanca en la abertura 9 de la pared 8 e inyectan fluido a presion en el interior de la camara 100 del envase 1’’’. Este fluido inunda la camara 100 y penetra en la capsula 2 a traves de la comunicacion que establecen los medios de rotura 10 o perforacion del adaptador 7. La bebida obtenida saldra de la capsula 2 por el extremo opuesto al de entrada, para lo cual se preve que el dispositivo 101 comprenda una placa de extraction, en si conocida, que perfore la lamina externa que eventualmente cierre la capsula 2 en el citado extremo de salida.Figs. 10a and 10b show a sequence of the procedure for the preparation of the beverage by using the 1 ’capsule. While Fig. 10a shows the container 1 '' when the adapter adopts the waiting position (A), Fig. 10b shows the moment in which the displacement of the means to ensure the tight coupling 104 of the device 101 in the direction of container 1 '' bumps into the annular projection 19 of the adapter and pulls it in the direction indicated by the arrow in Fig. 10b until the edge 20 of the adapter 7 is applied under pressure against the wing 17 or cantilever provided in the capsule 2 , then adopting the adapter operating position (B). Simultaneously, the injection means 102 are tightly coupled in the opening 9 of the wall 8 and inject fluid under pressure into the chamber 100 of the container 1 ’’. This fluid floods the chamber 100 and penetrates the capsule 2 through the communication established by the means of rupture 10 or perforation of the adapter 7. The beverage obtained will leave the capsule 2 at the opposite end to the inlet, for which it provides that the device 101 comprises an extraction plate, known per se, that punctures the outer lamina that eventually closes the capsule 2 at said exit end.
La parte de la capsula 2 que es rota o perforada por los medios de rotura 10 o perforation del adaptador 7 pueden comprender un elemento de cierre similar al del envase 1 de las Figs. 1 y 2 o estar formado por un fondo unido sin solution de continuidad con la pared lateral de la capsula 2, fondo formado por el mismo material del que esta hecha la capsula 2.The part of the capsule 2 that is broken or perforated by the rupture means 10 or perforation of the adapter 7 may comprise a closure element similar to that of the container 1 of Figs. 1 and 2 or be formed by a bottom joined without continuity solution with the side wall of the capsule 2, bottom formed by the same material from which the capsule 2 is made.
El procedimiento y el sistema de la invention pueden ponerse en practica con envases de diferentes materiales sin alterar la naturaleza del procedimiento o el sistema. Mientras la capsula 2 del envase 1 esta especialmente disenada para preservar el producto 5 contenido sin que el adaptador 7 contribuya a tal fin, es posible tambien proveer al envase de un adaptador 7 de material barrera, impermeable al oxlgeno, y a la capsula 2 de un elemento de cierre 3 sin estas propiedades o incluso sin elemento de cierre. En este caso no obstante la abertura o aberturas 9 en la pared 8 del adaptador deberan estar obturadas o cerradas por un medio o dispositivo que garantice su cierre estanco y el paso de oxlgeno, medio o dispositivo que debera ser retirado o manipulado para establecer comunicacion hidraulica entre la camara 100 y el exterior. Asimismo, es posible el empleo de envases que comprendan la combination de una capsula que contiene el producto para preparar la bebida y un correspondiente adaptador acoplado a la capsula por fuera, que la envuelve parcialmente y que provee al envase de una pared que determina, junto con una parte de la capsula, una camara sin que sea preciso desplazar el adaptador respecto de la capsula para garantizar el acople estanco entre la el adaptador y la citada capsula. En este caso o bien la parte de la capsula que determina una pared de la camara es permeable a los fluidos o el dispositivo empelado para la preparacion de la bebida puede incluir medios adecuados para romper o perforar esta parte de la capsula.The process and the system of the invention can be practiced with containers of different materials without altering the nature of the procedure or the system. While the capsule 2 of the container 1 is specially designed to preserve the contained product 5 without the adapter 7 contributing to that end, it is also possible to provide the container with an adapter 7 of oxygen-impermeable barrier material, and the capsule 2 of a closure element 3 without these properties or even without closure element. In this case, however, the opening or openings 9 in the wall 8 of the adapter must be sealed or closed by a means or device that guarantees its tight seal and the passage of oxygen, medium or device that must be removed or manipulated to establish hydraulic communication. between the camera 100 and the outside. Likewise, it is possible to use packages comprising the combination of a capsule containing the product to prepare the beverage and a corresponding adapter attached to the capsule on the outside, which partially wraps it and provides the container with a wall that determines, together with a part of the capsule, a camera without it being necessary to move the adapter with respect to the capsule to ensure the tight coupling between the adapter and said capsule. In this case either the part of the capsule that determines a wall of the chamber is permeable to fluids or the device used for the preparation of the beverage may include suitable means to break or pierce this part of the capsule.
