Description
Tapa de fácil apertura.Easy opening lid.
La presente invención, tapa de fácil apertura, concierne al ámbito de los envases metálicos, concretamente de los envases utilizados para la comercialización de alimentos, tales como latas de conserva, botes, etc, y se centra específicamente sobre los medios de apertura de su tapa, comúnmente denominados de "fácil apertura".The present invention, easy opening lid, concerns the field of metal packaging, specifically of packaging used for food marketing, such like canned cans, boats, etc., and it focuses specifically on the opening means of its lid, commonly referred to as "easy opening".
Específicamente la invención afecta a la clásica hendidura o incisión de que están provistas las tapas de este tipo de envases, para facilitar la apertura de los mismos mediante una anilla troqueladora-desgarradora.Specifically the invention affects the classic slit or incision that covers of this type are provided of containers, to facilitate the opening of the same by means of a punching-tearing ring.
En el ámbito preferente de aplicación práctica de la invención, el del envasado estanco de alimentos, se utilizan habitualmente envases metálicos sobre cuya tapa se establece una línea de incisión o hendidura perimetral, así como una anilla dotada de un vértice troquelador que queda superpuesto a la citada línea de incisión, de manera que en condiciones normales la anilla resulta paralela y adyacente a la tapa, mientras que durante la maniobra de apertura bascula sobre esta misma de manera que inicialmente y a través de su vértice troquelador provoca el inicio del rasgado de la tapa, y seguidamente se produce el desgarro total de la misma por tracción sobre la citada anilla.In the preferred scope of practical application of the invention, that of the sealed food packaging, are used usually metal containers on whose lid a incision line or perimeter groove, as well as a ring equipped with a die-cutting vertex that is superimposed on the aforementioned incision line, so that under normal conditions the ring it is parallel and adjacent to the lid, while during opening maneuver scales on it so that initially and through its die-cutting vertex causes the onset of tearing the lid, and then the total tear occurs of the same by traction on said ring.
Esta solución, perfectamente válida desde el punto de vista teórico, presenta en la práctica problemas derivados de un posicionamiento incorrecto de la anilla. En este sentido sucede con cierta frecuencia que, durante el proceso de fabricación de la anilla, o en los posteriores procesos de cierre, llenado, esterilización, manutención, etc, del envase, dicha anilla sufre un pequeño giro que provoca una modificación en la posición teórica prevista para su vértice troquelador con respecto a la incisión de la tapa, dado que la anilla gira sobre el punto de fijación de la misma a la tapa, acusadamente excéntrico con respecto a esta última, mientras que la línea de incisión describe una trayectoria paralela y próxima al contorno de dicha tapa, con lo que se produce un mayor o menor distanciamiento entre el vértice troquelador de la anilla y la incisión de la tapa, que provoca un aumento considerable del esfuerzo necesario para iniciar la operación de apertura, es decir, para producir el troquelado o rotura de la línea de incisión, a partir del cual se produce el posterior desgarramiento de la tapa.This solution, perfectly valid from the theoretical point of view, presents in practice derived problems of an incorrect positioning of the ring. In this sense it happens with some frequency that, during the manufacturing process of the ring, or in the subsequent processes of closing, filling, sterilization, maintenance, etc., of the container, said ring suffers a small turn that causes a change in the theoretical position provided for its punching vertex with respect to the incision of the cover, since the ring rotates on the fixing point of the same to the lid, sharply eccentric with respect to this last, while the incision line describes a trajectory parallel and close to the contour of said lid, which produces a greater or lesser distance between the die-cutting vertex of the ring and the incision of the lid, which causes an increase considerable effort required to start the operation of opening, that is, to produce the die cut or breakage of the incision line, from which the posterior is produced tearing of the lid.
Este aumento del esfuerzo contribuye a incrementar sustancialmente el número de tapas en las que la anilla no vence la incisión y no se logra abrir la tapa, produciéndose en ocasiones incluso la rotura de la anilla al deformarse el agujero que una ésta a la tapa mediante un remache, con el consecuente desprendimiento de la anilla e inutilización del mecanismo de apertura del envase.This increased effort contributes to substantially increase the number of caps on which the ring the incision does not expire and the lid cannot be opened, occurring in occasions even the ring breakage when the hole deforms that one is attached to the lid by means of a rivet, with the consequent ring detachment and useless mechanism opening of the container
La patente estadounidense US3,762,596-B, describe una tapa de lata con medios sobre la misma que impiden el giro de la anilla consistentes dichos medios en sendas proyecciones hacia fuera a ambos lados de la anilla. Asimismo presenta una línea de incisión cuya trayectoria en la zona de acción de la anilla es diferente a la del resto de dicha línea de incisión. Concretamente la línea de incisión en esa zona inicial de rotura es elíptica para distanciar la línea de incisión del borde de la lata y facilitar el proceso de fabricación de la lata. Los dispositivos empleados para impedir el giro de la anilla no aseguran, aunque si disminuyen, que durante la manipulación de la lata en los distintos procesos de fabricación de la misma esta no gire ligeramente. Debido a la configuración elíptica de la línea de incisión en su zona de rotura inicial, un mínimo giro de la anilla impedirá que el vértice troquelador de la misma incida sobre la zona de rotura inicial, derivándose por tanto los problemas anteriormente mencionados en la apertura de la lata.U.S. patent US3,762,596-B, describes a can lid with means on the same that prevent the rotation of the ring consistent said media in two outward projections on both sides of the ring. It also presents an incision line whose trajectory in the area of action of the ring is different from that of the rest of the ring incision line Specifically the incision line in that area Initial breakage is elliptical to distance the incision line from the edge of the can and facilitate the manufacturing process of the can. The devices used to prevent ring rotation they do not assure, although they diminish, that during the manipulation of the can in the different manufacturing processes of it is Do not turn slightly. Due to the elliptical configuration of the line of incision in its initial break zone, a minimum turn of the ring will prevent the punching vertex of the same impact on the initial break zone, thus deriving the problems previously mentioned in the opening of the can.
Las mejoras que la invención propone resuelven de forma plenamente satisfactoria la problemática anteriormente expuesta, asegurando una correcta funcionalidad de la anilla troqueladora, incluso cuando dicha anilla se encuentra sustancialmente girada con respecto a su posición teórica correcta.The improvements proposed by the invention solve in a fully satisfactory way the problem previously exposed, ensuring correct ring functionality die cutter, even when said ring is substantially rotated with respect to its theoretical position correct.
Para ello y de forma más concreta la invención consiste en variar la trayectoria de la línea de incisión, concretamente en el tramo de la misma enfrentado a la anilla troqueladora, de manera que manteniendo dicha línea de incisión una trayectoria general paralela y próxima al contorno de la tapa, en dicha zona de enfrentamiento a la anilla sufre dos inflexiones simétricas con respecto al punto teórico de troquelado, que enmarcan a un tramo intermedio en el que la trayectoria de la incisión es arqueada, concretamente con un centro de curvatura establecido en correspondencia con el remache de la anilla, de manera que ante un supuesto giro para esta última su vértice troquelador se sigue manteniendo sobre la citada incisión.For this and more specifically the invention consists in varying the trajectory of the incision line, specifically in the same section facing the ring die cutter, so that keeping said incision line a general path parallel and close to the contour of the lid, in said ring facing zone suffers two inflections symmetric with respect to the theoretical point of die cutting, which frame an intermediate section in which the trajectory of the incision is arched, specifically with a center of curvature established in correspondence with the rivet of the ring, of so that before a supposed turn for the latter its vertex die cutter is still maintained on the aforementioned incision.
La amplitud del citado tramo arqueado con curvatura en el remache de la anilla variará en función de diferentes criterios constructivos, debiendo ser éste mayor de 1º, aunque es conveniente que el mencionado tramo arqueado no supere los 80º.The amplitude of the aforementioned arched section with curvature in the rivet of the ring will vary depending on different constructive criteria, this must be greater than 1º, although it is convenient that the mentioned arched section does not exceed 80º.
El citado tramo arqueado se unirá al resto de la incisión a través de inflexiones también redondeadas, que "suavicen" la trayectoria de dicha incisión y que, en consecuencia, favorezcan el desgarro de la tapa.The aforementioned arched section will join the rest of the incision through also rounded inflections, which "soften" the trajectory of that incision and, in consequently, favor tearing the lid.
Evidentemente, las mejoras de la invención son aplicables tanto a tapas circulares como a tapas elípticas o rectangulares, que son las tres configuraciones habituales en este tipo de envases metálicos.Obviously, the improvements of the invention are applicable to both circular caps and elliptical caps or rectangular, which are the usual three configurations in this Type of metal containers.
En cualquier caso y de acuerdo con la estructuración descrita, se consigue que incluso ante un giro considerable de la anilla, que pueda llegar a ser de 10º a derechas o a izquierdas, dicha anilla mantenga su vértice troquelador situado sobre la línea de incisión, provocando el correcto troquelado de la misma con un esfuerzo mínimo.In any case and in accordance with the structuring described, it is achieved that even before a turn considerable of the ring, which can become 10º to right or on the left, said ring keeps its punching vertex located on the incision line, causing the correct punching of the same with minimal effort.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:
La figura 1.- Muestra una representación esquemática en planta de una tapa de apertura fácil para envases metálicos dotada de las mejoras objeto de la presente invención.Figure 1.- Shows a representation Schematic plan of an easy opening lid for packaging Metallic endowed with the improvements object of the present invention.
La figura 2.- Muestra un detalle ampliado de la tapa de la figura anterior, a nivel de la zona de la misma en la que se establecen dichas mejoras.Figure 2.- Shows an enlarged detail of the cover of the previous figure, at the level of the area of the same in the that these improvements are established.
La figura 3.- Muestra, según una representación similar a la figura 1, otro tipo de tapa convencional de apertura fácil, dotada también de las mejoras de la invención.Figure 3.- Shows, according to a representation similar to figure 1, another type of conventional opening lid easy, also equipped with the improvements of the invention.
A la vista de las figuras reseñadas, y más concretamente de la figura 1, puede observarse como las mejoras de la invención son aplicables a una tapa materializada en un cuerpo laminar (1), en este caso de contorno circunferencia, por estar dicha tapa destinada a un envase cilíndrico, dotada de una franja marginal (2) a través de la que, por agrafado o por cualquier otro medio, el cuerpo (1) se fija a la embocadura del envase, no representado, y contando por dentro de dicha franja marginal con una incisión o hendidura perimetral (3), destinada al rasgado de la tapa (1) durante la maniobra de apertura del envase, apertura que se lleva a cabo con la colaboración de una anilla (4) fijada al cuerpo (1) de la tapa con la colaboración de un remache (5), y dotada, en oposición a la anilla propiamente dicha (4), de un vértice troquelador (6) que debe quedar situado sobre la línea de incisión (3), sobre la que actúa cuando se efectúa manualmente la basculación de la anilla (4) sobre el remache (5) de fijación al cuerpo (1) de la tapa. La tapa (1) puede adoptar la configuración circular de la figura 1, la configuración rectangular de vértices redondeados de la figura 3 o cualquier otra configuración habitual en este tipo de envases, como por ejemplo la configuración elíptica, estando además normalmente dotada de embuticiones (7) que rigidizan su estructura.In view of the figures outlined, and more specifically of figure 1, it can be seen as the improvements of the invention are applicable to a cover materialized in a body laminar (1), in this case of circumference contour, for being said lid intended for a cylindrical container, provided with a strip marginal (2) through which, by engrafado or by any other medium, the body (1) is fixed to the mouth of the container, not represented, and counting within said marginal strip with an incision or perimeter groove (3), intended for tearing the lid (1) during the opening maneuver of the container, opening that it is carried out with the collaboration of a ring (4) fixed to the body (1) of the lid with the collaboration of a rivet (5), and provided, as opposed to the ring itself (4), of a punching point vertex (6) that must be located on the line of incision (3), on which it acts when the tilt of the ring (4) over the rivet (5) fixing to the body (1) of the lid. The cover (1) can adopt the configuration circular of figure 1, the rectangular configuration of vertices rounded in figure 3 or any other usual configuration in this type of packaging, such as the configuration elliptical, being also normally provided with embuticiones (7) that stiffen its structure.
Pues bien, a partir de esta estructuración básica y convencional, de acuerdo ya con la invención, la línea de incisión (3), en su zona de enfrentamiento a la anilla (4), sufre una variación en su trayectoria, determinante de un tramo de rotura (8) en forma de arco de circunferencia, con centro de curvatura (9) establecido en correspondencia con el centro del remache (5), como se observa especialmente en la figura 2, de manera que el punto medio de este tramo arqueado de rotura (8) se sitúa en correspondencia con el punto teórico (10) previsto para el accionamiento del vértice troquelador (6) de la anilla (4), cuando ésta se encuentra correctamente ubicada en el contexto de la tapa (1).Well, from this structuring basic and conventional, according to the invention, the line of incision (3), in its zone of confrontation with the ring (4), suffers a variation in its trajectory, determining a breakage section (8) in the form of an arc of circumference, with a center of curvature (9) established in correspondence with the center of the rivet (5), as it is especially observed in figure 2, so that the point middle of this arcuate section of breakage (8) is located in correspondence with the theoretical point (10) provided for actuation of the punching vertex (6) of the ring (4), when it is correctly located in the context of the lid (one).
Esto trae consigo, como ya se ha dicho con anterioridad, que ante un eventual giro de la anilla (4) en cualquier momento a lo largo del proceso de manipulación del envase, su vértice troquelador (6) se siga manteniendo perfectamente enfrentado a la línea de incisión (3), concretamente a lo largo de este tramo de rotura (8), con lo que se asegura que las condiciones de rasgado sean óptimas.This brings with it, as already stated with before, that before a possible turn of the ring (4) in any time throughout the process of handling the container, its die cutter vertex (6) is still maintained perfectly facing the incision line (3), specifically along this section of breakage (8), which ensures that the Tear conditions are optimal.
Como también se ha dicho con anterioridad, la amplitud del citado tramo de rotura (8) con centro de curvatura (9) coincidente con el eje del remache (5) puede variar entre 1º y 80º, siendo preferiblemente la amplitud de dicho arco de 20º, 10º a cada lado del punto teórico (10) previsto para el accionamiento del vértice troquelador (6) de la anilla (4), cuando ésta se encuentra correctamente ubicada en el contexto de la tapa (1), y dicho tramo de rotura (8) se unirá al resto de la línea de incisión (3) mediante inflexiones dobles, contrapuestas y arqueadas (11-11'), que faciliten el desgarro de la tapa (1), evitando la existencia de acodamientos vivos en dicha línea de incisión (3) que pudieran repercutir negativamente en el rasgado de la tapa.As also stated previously, the amplitude of said section of breakage (8) with center of curvature (9) coinciding with the axis of the rivet (5) can vary between 1º and 80º, preferably the amplitude of said arc of 20 °, 10 ° at each side of the theoretical point (10) provided for the actuation of the punching point vertex (6) of the ring (4), when it is correctly located in the context of the cover (1), and said section Breaking (8) will join the rest of the incision line (3) by double, opposite and arched inflections (11-11 '), which facilitate tearing of the lid (1), avoiding the existence of live couplings in said line of incision (3) that could have a negative impact on the tearing of the lid
