El mismo solicitante de la CH605293 solicitó la ES2061284 con fecha 28 de enero de 1.992, sobre un cartucho cerrado con filtro, que alcanza a concretar el modo de debilitamiento de la capa protectora anterior. ES 2097831 de 4 de mayo de 1.992, del mismo solicitante de la CH605293, por cartucho cerrado para la confección de una bebida, divulga la membrana de salida, expresada como opérculo en distintas formas, medidas y grosores, en forma básicamente similar a la FR2211924 antes mencionada, eventualmente dotado de filtro. Se aprecia una profusión de documentos muy amplia, con divulgaciones muy anteriores a veinte años atrás, y que sin perjuicio de que también existen otros documentos posteriores, esta patente va a centrar su punto de partida en aquella tecnología ya obsoleta, divulgada, caducada por transcurso del tiempo, para presentar las innovaciones derivadas de las características del producto, del material y del modo de realizarlo. The same applicant of CH605293 requested ES2061284 dated January 28, 1992, on a closed cartridge with filter, which manages to specify the weakening mode of the previous protective layer. ES 2097831 of May 4, 1992, of the same applicant of CH605293, by closed cartridge for the preparation of a beverage, discloses the outlet membrane, expressed as an operculum in different shapes, measures and thicknesses, in a manner basically similar to FR2211924 mentioned above, eventually equipped with a filter. There is a very wide profusion of documents, with disclosures well before twenty years ago, and without prejudice to the existence of other subsequent documents, this patent is going to focus its starting point on that technology that is already obsolete, disclosed, expired for the duration of time, to present the innovations derived from the characteristics of the product, the material and the way of carrying it out.
Explicación de la invención Explanation of the invention.
La presente invención consiste en una cápsula para cafeteras monodosis que tiene como característica ser idónea, sencilla, apta para las máquinas en las que se utilizaba el cartucho de la patente CH605293 y con aquellas máquinas de diseño posterior en las que utilizan las mismas cápsulas que dichas máquinas anteriores, y particularmente en las que se utiliza la misma tecnología de retención de cápsula, de inyección de agua y de desecho de producto, y cuya estructura supone la posibilidad de ser fabricadas en un material plástico con sellado anterior de aluminio, y que está reforzada y debilitada en las zonas adecuadas para desarrollar la función sin producir problemas derivados de la deformación del plástico, arrugado, reducción, falta de ajuste, pérdidas o cualquier otra. The present invention consists of a capsule for single-dose coffee machines whose characteristic is to be suitable, simple, suitable for the machines in which the CH605293 patent cartridge was used and with those subsequent design machines in which they use the same capsules as said previous machines, and particularly in which the same capsule retention, water injection and product disposal technology is used, and whose structure implies the possibility of being manufactured in a plastic material with a previous aluminum seal, and which is reinforced and weakened in the appropriate areas to develop the function without producing problems derived from the deformation of the plastic, wrinkling, reduction, lack of adjustment, losses or any other.
La geometría proporcionada a la base menor de la cápsula con dos porciones troncocónicas separadas axialmente logra evitar la deformación que se produce en el caso de que ambas porciones formen un único tronco de cono, debido a que se aumenta su momento de inercia respecto a un plano perpendicular a la dirección del eje del tronco de cono, y, por lo tanto una mayor resistencia respecto a la dirección de incidencia de los medios de perforación. The geometry provided to the smaller base of the capsule with two axially separated frustoconical portions manages to avoid deformation that occurs in the case that both portions form a single cone trunk, because their moment of inertia is increased relative to a plane perpendicular to the direction of the cone trunk axis, and, therefore, a greater resistance to the direction of incidence of the drilling means.
Además, la geometría proporcionada al reborde de la base mayor, provista de unos rebordes exterior e interior, y un grosor determinado, dotan a la cápsula de una resistencia en la zona de sujeción en las máquinas correspondientes que impide su deformación, y por tanto de goteos indeseados, al tiempo que es lo suficientemente fina en la zona en que apoya la corona de sujeción de la máquina, de modo que su comportamiento es el deseado. Si fuera más grueso tendría mayor resistencia, pero no sería adecuada para su uso en determinadas máquinas, de modo que con la configuración que se describe dichas cápsulas son idóneas para su uso en cualquier máquina para esta configuración de cápsula. In addition, the geometry provided to the flange of the major base, provided with outer and inner flanges, and a certain thickness, give the capsule a resistance in the area of subjection in the corresponding machines that prevents its deformation, and therefore of unwanted drips, while it is thin enough in the area that supports the machine's clamping crown, so that its behavior is as desired. If it were thicker it would have greater resistance, but it would not be suitable for use in certain machines, so that with the configuration described, said capsules are suitable for use in any machine for this capsule configuration.

Al menos las nervaduras (5) están provistas de una primera porción (51) de unión con la base menor (4), y particularmente con la primera porción (43) de dicha base menor (4), que tienen un mayor grosor que el resto de la nervadura; estas nervaduras alcanzan normalmente una cuarta parte de la altura del cuerpo en forma de tronco de cono (2), y con una dimensión radial de entre 0,5mm y 4mm y un grosor de entre 0,2mm y 2,5mm . Algunas o todas estas nervaduras pueden, no obstante, estar prolongadas parcial o totalmente hasta la base mayor (3), en la que la porción prolongada (52) tiene igual o menor dimensión radial e igual o menor grosor que la primera porción (51) . Según una realización idónea, el número de nervaduras (5) es seis. In the part corresponding to the inside of the capsule in the inner portion (40) a central greasing (44) is formed with respect to the wall forming said inner portion (40). The cone-shaped body (2) preferably has a thickness greater than 0.6 mm and optimally 0.9 mm, and preferably is provided internally with a set of ribs (5) in planes transverse to the surface of said body (planes that pass through the axis of the cone trunk). At least the ribs (5) are provided with a first portion (51) of connection with the minor base (4), and particularly with the first portion (43) of said minor base (4), which are thicker than the rest of the rib; these ribs normally reach a quarter of the height of the body in the form of a cone trunk (2), and with a radial dimension between 0.5mm and 4mm and a thickness between 0.2mm and 2.5mm. Some or all of these ribs may, however, be partially or totally extended to the major base (3), in which the prolonged portion (52) has the same or smaller radial dimension and is equal or smaller than the first portion (51) . According to an ideal embodiment, the number of ribs (5) is six.
La base mayor esta rodeada de un reborde en un plano transversal, que está provisto inferiormente (en la zona orientada hacia la base menor) de una acanaladura perimetral (61); la acanaladura perimetral (61) presenta un reborde externo (62), orientado hacia abajo (hacia la base menor), con un grosor de entre 0,5 mm y 0,8 mm, y una altura de entre 1,2 mm y 1,5 mm, y preferentemente 1,3 mm ; según una opción comprende también un reborde interno (63), también orientado hacia abajo; el reborde interno (63) está dispuesto de forma contigua al cuerpo en forma de trono de cono (2) con un grosor total de entre 1,3 mm y 1,85 mm, y cuya superficie inferior está provista de unas pequeñas acanaladuras concéntricas (64); según una opción, dichas acanaladuras tienen una altura de 0, 15 mm ; según una opción preferida, se disponen cuatro acanaladuras concéntricas (64) formadas por un dentado de igual sección y perfil triangular, con una altura de entre 0,9 mm y 1,2 mm . The major base is surrounded by a flange in a transverse plane, which is provided inferiorly (in the area oriented towards the minor base) of a perimeter groove (61); the perimeter groove (61) has an external flange (62), oriented downwards (towards the base smaller), with a thickness between 0.5 mm and 0.8 mm, and a height between 1.2 mm and 1.5 mm, and preferably 1.3 mm; according to one option it also comprises an internal flange (63), also oriented downwards; the internal flange (63) is arranged contiguously to the cone-shaped body (2) with a total thickness of between 1.3 mm and 1.85 mm, and whose lower surface is provided with small concentric grooves ( 64); according to one option, said grooves have a height of 0.15 mm; According to a preferred option, four concentric grooves (64) formed by a tooth of the same section and triangular profile are arranged, with a height between 0.9 mm and 1.2 mm.
Las dimensiones indicadas, particularmente los grosores de las distintas paredes, permiten una estabilidad dimensional que permite que la cápsula sea perforada sin deterioro de su integridad, y al mismo tiempo no es dimensionalmente vulnerable a las temperaturas que tienen lugar en la elaboración de las bebidas. The indicated dimensions, particularly the thicknesses of the different walls, allow dimensional stability that allows the capsule to be perforated without deterioration of its integrity, and at the same time it is not dimensionally vulnerable to the temperatures that take place in the production of the beverages.
La superficie interior del cuerpo en forma de tronco de cono (2) puede estar dotada de una o más nervaduras (7), normalmente nervaduras perimetrales paralelas. The inner surface of the cone-shaped body (2) can be provided with one or more ribs (7), usually parallel perimeter ribs.
