CÁPSULA PARA REALIZAR INFUSIONES EN MÁQUINAS Sector de la técnica CAPSULE TO MAKE INFUSIONS IN MACHINES Technical sector
La presente invención está relacionada con la presentación de productos destinados para la preparación de infusiones, proponiendo una cápsula contenedora de una cantidad dosificada de producto para infusiones, con unas características de realización de dicha cápsula que la hacen constructivamente ventajosa en las condiciones necesarias para ser utilizada eficazmente en las máquinas de preparación de infusiones. The present invention is related to the presentation of products intended for the preparation of infusions, proposing a capsule containing a dosed amount of product for infusions, with performance characteristics of said capsule that make it constructively advantageous under the conditions necessary to be used. effectively in infusion preparation machines.
Estado de la técnica Entre las distintas formas de presentación y comercialización de productos destinados para realizar infusiones, como el café y otros, una solución que actualmente está muy en práctica es la presentación en cápsulas contenedoras de una cantidad dosificada de producto de infusión. Un tipo convencional de cápsulas al respecto, son unas cápsulas constituidas por un pequeño recipiente troncoconoide de lámina de aluminio o de plástico, con cierre mediante una lámina fijada sobre la embocadura, alojando en el interior el producto de infusión. State of the art Among the different forms of presentation and marketing of products intended for infusions, such as coffee and others, a solution that is currently very much in practice is the presentation in capsules containing a dosed quantity of infusion product. A conventional type of capsules in this regard, are capsules constituted by a small trunk-shaped container of aluminum or plastic foil, with closure by means of a foil fixed on the mouth, housing the infusion product inside.
Dichas cápsulas están destinadas para utilizarse en máquinas de preparación de infusiones, en las cuales se calienta un líquido, fundamentalmente agua, que se proyecta sobre la lámina de cierre de la cápsula, para que penetre en el interior, en donde se impregna de la sustancia del producto de infusión, realizándose así una infusión que se suministra por una salida al exterior de la máquina. Existen máquinas para preparar infusiones con dichas cápsulas, que disponen de un cabezal provisto con agujas, mediante el cual se perfora la lámina de cierre de las cápsulas para que el líquido caliente a presión pueda entrar al interior y establecer en contacto con el producto de infusión contenido dentro de las cápsulas. Para esa operación las cápsulas se tienen que sujetar en una posición concreta dentro de la máquina de preparación de las infusiones, lo cual se determina mediante una relación entre la forma de las cápsulas y la forma del alojamiento de inserción en las máquinas, de manera que las cápsulas solo se pueden introducir en la máquina en una posición. Pero además, la sujeción de las cápsulas se tiene que realizar con estanqueidad, para que la función de la infusión se realice con efectividad mediante el líquido caliente a presión. Said capsules are intended for use in infusion preparation machines, in which a liquid, essentially water, is projected onto the closure sheet of the capsule, so that it penetrates inside, where it is impregnated with the substance. of the infusion product, thus carrying out an infusion that is supplied by an outlet to the outside of the machine. There are machines for preparing infusions with said capsules, which have a head provided with needles, through which the capsule closure sheet is perforated so that the hot pressurized liquid can enter inside and establish contact with the infusion product content inside the capsules. For this operation the capsules must be held in a specific position within the infusion preparation machine, which is determined by a relationship between the shape of the capsules and the shape of the insertion housing in the machines, so that the capsules can only be inserted into the machine in one position. But in addition, the clamping of the capsules has to be done tightly, so that the function of the infusion is carried out effectively by means of the hot liquid under pressure.
Para esa sujeción con estanqueidad, las cápsulas realizadas de plástico se determinan con un reborde periférico en la embocadura, de un material plástico más blando que el resto el cuerpo de la cápsula, lo cual hace que la realización constructiva de dichas cápsulas sea complicada y costosa; en tanto que las cápsulas realizadas de lámina de aluminio se determinan con un reborde periférico en la embocadura, sobre el cual se aplica un recubrimiento de un material elástico que se aplica como una pintura sobre dicho reborde de la cápsula; resultando esta solución también complicada y costosa, además de que la capa de material elástico aplicada como recubrimiento no asegura una efectividad de junta para conseguir la estanqueidad en la sujeción de las cápsulas. For that tightness, the capsules made of plastic are determined with a peripheral flange at the mouth, of a softer plastic material than the rest of the capsule body, which makes the constructive realization of said capsules complicated and expensive ; while the capsules made of aluminum foil are determined with a peripheral flange in the mouth, on which a coating of an elastic material is applied which is applied as a paint on said flange of the capsule; This solution is also complicated and expensive, in addition to the fact that the layer of elastic material applied as a coating does not ensure a seal effectiveness to achieve the tightness of the capsules.
Objeto de la invención Object of the invention
De acuerdo con la invención se propone una cápsula para infusiones, con una realización que aporta unas características de realización estructural que la hacen ventajosa constructivamente y para la utilización en máquinas de preparación de infusiones. According to the invention, a capsule for infusions is proposed, with an embodiment that provides structural performance characteristics that make it constructively advantageous and for use in infusion preparation machines.
Esta cápsula objeto de la invención consta de un cuerpo recipiente de forma troncoconoide, realizado de lámina de aluminio y abierto por la base mayor, determinando dicho cuerpo en el borde de la embocadura un ala periférica hacia el exterior, sobre la cual se fija una lámina de cierre cubriendo la embocadura, incorporándose además sobre dicha ala periférica una anilla de material elástico, la cual se fija solidariamente a esa ala periférica del cuerpo recipiente mediante termo-soldadura. This capsule object of the invention consists of a container body with a truncated conoid shape, made of aluminum foil and opened by the main base, said body at the edge of the mouth determining a peripheral wing towards the outside, on which a sheet is fixed of closing covering the mouth, also incorporating on said peripheral wing a ring of elastic material, which is fixedly attached to that peripheral wing of the container body by heat welding.
Se tiene así una cápsula en la que la anilla de material elástico hace las funciones de junta para la estanqueidad de la sujeción de la cápsula en las máquinas de preparación de infusiones, con una gran efectividad para dicha función, ya que constituye una capa de material elástico que al ser comprimida por presión establece una perfecta estanqueidad; estando prevista dicha anilla además en el borde exterior con un regruesado que determina a modo de un reborde, el cual incrementa aún más la efectividad para establece la estanqueidad cuando se hace un apresado sobre el ala periférica para sujetar la cápsula en las máquinas de preparación de infusiones. Además, al ser la anilla de material elástico un elemento independiente que se fija después de la conformación del cuerpo recipiente de la cápsula, no afecta a la realización de dicho cuerpo recipiente y la fijación posterior de dicha anilla sobre el ala periférica de dicho cuerpo recipiente de la cápsula, es muy fácil de realizar. There is thus a capsule in which the ring of elastic material acts as a seal for sealing the capsule in the infusion preparation machines, with great effectiveness for said function, since it constitutes a layer of material elastic that when compressed by pressure establishes a perfect seal; said ring being also provided on the outer edge with a backing which determines as a flange, which further increases the effectiveness to establish the tightness when a clamping is made on the peripheral wing to hold the capsule in the preparation machines of infusions Furthermore, since the ring of elastic material is an independent element that is fixed after the conformation of the container body of the capsule, does not affect the realization of said container body and the subsequent fixation of said ring on the peripheral wing of said container body of the capsule, it is very easy to perform.
Por todo ello, la cápsula preconizada resulta de unas características de realización muy ventajosas, adquiriendo vida propia y carácter preferente respecto de las cápsulas convencionales del mismo tipo que se utilizan para la preparación de infusiones en máquinas de dicha función. Therefore, the recommended capsule results from very advantageous performance characteristics, acquiring its own life and preferential character with respect to conventional capsules of the same type that are used for the preparation of infusions in machines of said function.

Descripción detallada de la invención El objeto de la invención se refiere a una cápsula para infusiones, de las que se utilizan en máquinas de preparación de infusiones, en las cuales se proyecta un líquido a presión para que penetre en la cápsula y se impregne de la sustancia de un producto de infusión contenido en el interior. La cápsula preconizada consta de un cuerpo recipiente (1) realizado de lámina de aluminio, presentando una forma troncoconoide abierta por la base mayor, en donde se dispone una lámina de cierre (2) que cubre la embocadura, yendo en el interior una cantidad dosificada de un producto (3) de infusión. En el borde de la embocadura el cuerpo recipiente (1) posee un ala periférica (4) hacia el exterior, sobre la cual se fija la lámina de cierre (2) estableciendo una obturación hermética que mantiene al producto (3), con su aroma y efluentes, confinados en el interior. DETAILED DESCRIPTION OF THE INVENTION The object of the invention relates to an infusion capsule, of which are used in infusion preparation machines, in which a pressurized liquid is projected to penetrate the capsule and be impregnated with the substance of an infusion product contained inside. The recommended capsule consists of a container body (1) made of aluminum foil, presenting a trunk-shaped conoid shape opened by the major base, where a closure sheet (2) is provided that covers the mouth, going inside a dosed quantity of an infusion product (3). At the edge of the mouth the container body (1) has a peripheral wing (4) towards the outside, on which the closure sheet (2) is fixed establishing a hermetic seal that keeps the product (3), with its aroma and effluents, confined inside.
Sobre esa ala periférica (4) del borde de la embocadura del cuerpo recipiente (1) se dispone además una anilla (5) accesoria de material elástico, la cual se fija de una manera solidaria mediante termo-soldadura sobre la mencionada ala periférica (4). On that peripheral wing (4) of the edge of the mouth of the container body (1) there is also an accessory ring (5) of elastic material, which is fixed in a solidary manner by heat welding on said peripheral wing (4 ).
Dicha anilla (5) accesoria posee un regruesamiento (5.1) en el borde exterior, mediante el cual determina a modo de un reborde en el contorno exterior del ala periférica (4), sobre la cual el resto de la anilla (5) determina una capa de material elástico que queda sobrepuesta a dicha ala periférica (4). Said accessory ring (5) has a thickening (5.1) on the outer edge, by means of which it determines by way of a flange on the outer contour of the peripheral wing (4), on which the rest of the ring (5) determines a layer of elastic material that is superimposed on said peripheral wing (4).
Con ello resulta una cápsula en la que el cuerpo recipiente (1) queda cerrado de manera hermética por la lámina de cierre (2), conteniendo en el interior al producto (3) de infusión totalmente protegido y aislado del exterior, presentando el conjunto una forma adecuada para la inserción en las máquinas de preparación de infusiones y sujeción en el interior de las mismas en posición para ser taladrada la lámina de cierre (2) por un cabezal de agujas, con el fin de que una proyección de líquido caliente a presión penetre el interior para su impregnación con la sustancia del producto (3), realizándose así la infusión. Para esa función, la anilla (5) de material elástico fijada sobre el ala periférica (4) del borde de la embocadura del cuerpo recipiente (1), hace de junta para que la cápsula pueda sujetarse con una gran efectividad de estanqueidad por apresado sobre el ala periférica (4), permitiendo así optimizar la función operativa de la realización de las infusiones en las máquinas de utilización de la cápsula. This results in a capsule in which the container body (1) is closed tightly by the closure sheet (2), containing inside the infusion product (3) fully protected and isolated from the outside, the assembly presenting a suitable form for the insertion in the infusion preparation machines and clamping inside them in position to be drilled the closing sheet (2) by a needle head, so that a projection of hot liquid under pressure penetrate the interior for impregnation with the substance of the product (3), thus making the infusion. For this function, the ring (5) of elastic material fixed on the peripheral wing (4) of the edge of the mouth of the container body (1), acts as a seal so that the capsule can be held with a great sealing effectiveness by pressing on the peripheral wing (4), thus allowing to optimize the operative function of the realization of infusions in the machines using the capsule.
