Description
Tapa de fácil apertura.Easy opening lid.
La presente invención, una tapa de fácil apertura, se aplica al campo de los recipientes de metal, específicamente de aquellos recipientes usados para la comercialización de alimentos, tales como latas, botes, etc., y se centra específicamente en los medios de apertura de la tapa de los mismos, habitualmente denominados "de fácil apertura".The present invention, an easy cover opening, applies to the field of metal containers, specifically of those containers used for food marketing, such as cans, cans, etc., and it specifically focuses on the opening means of the lid of the themselves, usually called "easy to open".
La presente invención se refiere específicamente a la ranura o corte clásico que están previstos en tapas de este tipo de recipientes, para facilitar la apertura de los mismos mediante una lengüeta anular de perforación y arranque.The present invention specifically relates to the classic groove or cut that are provided in the covers of this type of containers, to facilitate the opening of the same by means of an annular tongue of perforation and start.
En el alcance preferido de aplicación práctica de la invención, el envasado hermético de alimentos, se usan de manera convencional recipientes de metal, cuya tapa está dotada de una línea de corte o ranura perimétrica, así como de una lengüeta anular dotada de un vértice de perforación que se solapa con dicha línea de corte, de manera que en condiciones normales, la lengüeta anular es paralela y adyacente a la tapa, mientras que durante la maniobra de apertura, bascula sobre la misma de manera que inicialmente, y a través de su vértice de perforación, provoca el comienzo del arranque de la tapa, y entonces provoca el arranque completo de la misma tirando de dicha lengüeta anular.In the preferred scope of practical application of the invention, the hermetic food packaging, are used of conventional way metal containers, whose lid is equipped with a cutting line or perimeter groove, as well as a tongue annular provided with a perforation vertex that overlaps with said cutting line, so that under normal conditions, the tongue annular is parallel and adjacent to the lid, while during opening maneuver, swings over it so that initially, and through its drilling vertex, it causes start of the lid start, and then causes the start full of it by pulling said ring tongue.
Esta solución, perfectamente válida desde el
punto de vista teórico, presenta inconvenientes en la práctica
derivados de una colocación incorrecta de la lengüeta anular. En
este aspecto, ocurre con bastante frecuencia que, durante el
proceso de fabricación de la lengüeta anular, o en los procesos
posteriores de sellado, llenado, esterilización, manipulación, etc.
del recipiente, dicha lengüeta anular sufre un ligero giro,
provocando una modificación de la posición teórica prevista para su
vértice de perforación con respecto al corte de la tapa, ya que la
lengüeta anular gira alrededor del punto en el que está fijada a la
tapa, considerablemente excéntrico con respecto a la última,
mientras que la línea de corte define una trayectoria paralela y
próxima al contorno de dicha tapa, por lo que se produce más o
menos separación entre el vértice de perforación de la lengüeta
anular y el corte de la tapa, provocando un aumento significativo de
la fuerza necesaria para comenzar la operación de apertura, es
decir, para provocar la perforación o rotura de la línea de corte,
tras lo cual la tapa se arranca posterior-
mente.This solution, which is perfectly valid from a theoretical point of view, has problems in practice due to incorrect positioning of the ring tongue. In this aspect, it happens quite frequently that, during the manufacturing process of the ring tongue, or in the subsequent processes of sealing, filling, sterilization, handling, etc. of the container, said annular tongue undergoes a slight rotation, causing a modification of the theoretical position provided for its perforation vertex with respect to the cut of the lid, since the annular tongue rotates around the point at which it is fixed to the lid, considerably eccentric with respect to the last one, while the cutting line defines a path parallel and close to the contour of said cover, whereby more or less separation occurs between the piercing vertex of the annular tongue and the cut of the lid , causing a significant increase in the force necessary to begin the opening operation, that is, to cause the perforation or breakage of the cutting line, after which the cover is torn off later-
mind.
Este aumento de fuerza contribuye a aumentar de manera significativa el número de tapas en las que la lengüeta anular no puede superar el corte y no abre la tapa, incluso provocando en ocasiones que la lengüeta anular se rompa ya que el orificio que conecta la lengüeta anular a la tapa mediante un remache se deforma, con la liberación posterior de la lengüeta anular y la incapacidad de usar el mecanismo de apertura del recipiente.This increase in strength helps increase significantly the number of caps on which the tongue annular can not overcome the cut and does not open the lid, even sometimes causing the ring tongue to break as the hole that connects the ring tongue to the cover by means of a rivet deforms, with the posterior release of the tongue annul and the inability to use the opening mechanism of the container.
La patente estadounidense US3.762.596-B da a conocer un tapa de lata que tiene medios sobre la misma que impiden el giro de la lengüeta anular, consistiendo dichos medios en salientes hacia fuera respectivos en ambos lados de la lengüeta anular. También tiene una línea de corte cuya trayectoria en la zona de funcionamiento de la lengüeta anular es distinta de la del resto de dicha línea de corte. Específicamente, la línea de corte en esa zona de rotura inicial es elíptica para separar la línea de corte del borde de la lata y para facilitar el proceso de fabricación de la lata. Los dispositivos usados para impedir el giro de la lengüeta anular no garantizan que, durante la manipulación de la lata en los distintos procesos de fabricación de la misma, no girará ligeramente, aunque sí reduce dicho giro. Debido a la configuración elíptica de la línea de corte en su zona de rotura inicial, un giro mínimo de la lengüeta anular impedirá que el vértice de perforación de la misma actúe sobre dicha zona de rotura inicial, originando por tanto los inconvenientes mencionados anteriormente a la hora de abrir la lata.U.S. patent US3,762,596-B discloses a can lid that has means thereon preventing the rotation of the ring tongue, said means consisting of respective outward projections in both sides of the ring tongue. It also has a cut line whose trajectory in the operating area of the ring tongue it is different from that of the rest of said cut line. Specifically, the cut line in that initial break zone is elliptical to separate the cutting line from the edge of the can and to facilitate the can manufacturing process. The devices used to prevent rotation of the ring tongue do not guarantee that, during the manipulation of the can in the different processes of manufacture of the same, will not turn slightly, although it does reduce Said turn. Due to the elliptical configuration of the cutting line in its initial break zone, a minimum rotation of the ring tongue it will prevent the drilling vertex of it from acting on said initial break zone, thus originating the drawbacks mentioned above when opening the can.
Las mejoras propuestas por la invención resuelven de manera satisfactoria el inconveniente explicado anteriormente, garantizando un funcionamiento apropiado de la lengüeta anular de perforación, incluso cuando dicha lengüeta anular se gira significativamente con respecto a su posición correcta teórica.The improvements proposed by the invention satisfactorily solve the problem explained previously, ensuring proper operation of the annular piercing tongue, even when said tongue annular rotates significantly with respect to its position theoretical correct.
Por tanto, de manera más específica, la invención supone cambiar la trayectoria de la línea de corte, específicamente en el segmento de la misma enfrentado a la lengüeta anular de perforación, de manera que manteniendo dicha línea de corte una trayectoria general paralela y próxima al contorno de la tapa, en dicha zona enfrentada a la lengüeta anular, sufre dos inflexiones simétricas con respecto al punto de perforación teórico, que enmarcan un segmento intermedio en el que la trayectoria del corte es arqueada, específicamente con un centro de curvatura dispuesto en correspondencia con el remache de la lengüeta anular, de manera que tras un giro de la lengüeta anular, su vértice de perforación se mantiene en su lugar sobre dicho corte.Therefore, more specifically, the invention involves changing the trajectory of the cutting line, specifically in the segment of it facing the tongue annular drilling, so that maintaining said line of cut a general path parallel to the contour of the cover, in said area facing the ring tongue, suffers two symmetrical inflections with respect to the theoretical drilling point, that frame an intermediate segment in which the trajectory of the cut is arched, specifically with a center of curvature arranged in correspondence with the rivet of the ring tongue, so that after a turn of the ring tongue, its vertex of perforation is held in place over said cut.
La amplitud de dicho segmento arqueado con una curvatura en el remache de la lengüeta anular variará según distintos criterios de construcción, siendo esta amplitud necesariamente superior a 1º, aunque es conveniente que dicho segmento arqueado no supere los 80º.The amplitude of said arched segment with a curvature in the rivet of the ring tongue will vary according to different construction criteria, this amplitude being necessarily higher than 1, although it is convenient that said arched segment does not exceed 80º.
Dicho segmento arqueado se unirá al resto del corte a través de inflexiones también redondeadas que "suavizan" la trayectoria de dicho corte y que, en consecuencia, favorecen el arranque de la tapa.Said arched segment will join the rest of the cut through also rounded inflections that "soften" the trajectory of said cut and that, in Consequently, they favor the start of the lid.
Evidentemente, las mejoras de la invención pueden aplicarse a tapas tanto circulares como elípticas o rectangulares, que son las tres configuraciones convencionales en este tipo de recipientes de metal.Obviously, the improvements of the invention they can be applied to both circular and elliptical caps or rectangular, which are the three conventional configurations in This type of metal containers.
En cualquier caso y según la estructura descrita, se logra que, incluso debido a un giro significativo de la lengüeta anular, que puede alcanzar los 10º a la derecha o a la izquierda, dicha lengüeta anular mantenga su vértice de perforación sobre la línea de corte, provocando la perforación apropiada de la misma con una fuerza mínima.In any case and according to the structure described, it is achieved that, even due to a significant turn of the ring tongue, which can reach 10º to the right or to the left, said ring tongue keep its piercing vertex on the cutting line, causing the proper perforation of the same with minimal force.
Para complementar la descripción que está realizándose y con el fin de ayudar a comprender mejor las características de la invención según una realización práctica preferida de la misma, se adjunta un conjunto de dibujos a dicha descripción como una parte integrante de la misma que, con un carácter ilustrativo y no limitativo, muestran lo siguiente:To complement the description that is performing and in order to help you better understand the characteristics of the invention according to a practical embodiment preferred thereof, a set of drawings is attached to said description as an integral part of it that, with a Illustrative and non-limiting, show the following:
La figura 1 muestra una vista en planta esquemática de una tapa de fácil apertura para recipientes de metal dotada de las mejoras objeto de la presente invención.Figure 1 shows a plan view schematic of an easy opening lid for metal containers equipped with the improvements object of the present invention.
La figura 2 muestra una vista en detalle ampliada de la tapa de la figura anterior, en la zona de la misma en la que se realizan dichas mejoras.Figure 2 shows a detail view enlarged of the cover of the previous figure, in the zone of the same in which these improvements are made.
La figura 3 muestra, según una vista similar a la figura 1, otro tipo de tapa de fácil apertura convencional, también dotada de las mejoras de la invención.Figure 3 shows, according to a view similar to Figure 1, another type of conventional easy open lid, also endowed with the improvements of the invention.
A la vista de las figuras, y más específicamente de la figura 1, puede verse cómo las mejoras de la invención pueden aplicarse a una tapa hecha de un cuerpo (1) laminar, que tiene un contorno circunferencial en este caso, ya que esta tapa está prevista para un recipiente cilíndrico, dotado de una tira (2) marginal a través de la que, mediante sellado por costura o mediante cualquier otro medio, el cuerpo (1) se fija a la abertura del recipiente, no mostrada, y está dotado dentro de dicha tira marginal de un corte o ranura (3) perimétrica que está prevista para arrancar la tapa (1) durante la maniobra de apertura del recipiente, apertura que se realiza con la colaboración de una lengüeta (4) anular fijada al cuerpo (1) de la tapa con la colaboración de un remache (5), y dotado de, en oposición a la propia lengüeta (4) anular, un vértice (6) de perforación que debe situarse sobre la línea (3) de corte sobre la que actúa cuando la lengüeta (4) anular se bascula manualmente sobre el remache (5) que fija la lengüeta anular al cuerpo (1) de la tapa. La tapa (1) puede adoptar la configuración circular de la figura 1, la configuración rectangular con vértices redondeados de la figura 3, o cualquier otra configuración convencional en este tipo de recipientes, tales como una configuración elíptica, que normalmente también está dotada de embuticiones (7) refuerzan su
\hbox{estructura.} In view of the figures, and more specifically of Figure 1, it can be seen how the improvements of the invention can be applied to a cover made of a laminar body (1), which has a circumferential contour in this case, since this cover it is provided for a cylindrical container, provided with a marginal strip (2) through which, by seam sealing or by any other means, the body (1) is fixed to the opening of the container, not shown, and is provided within said marginal strip of a perimeter cut or groove (3) that is intended to tear off the lid (1) during the opening maneuver of the container, opening which is carried out in collaboration with an annular tongue (4) fixed to the body ( 1) of the cover with the collaboration of a rivet (5), and provided, as opposed to the ring tongue (4) itself, a drilling vertex (6) that must be placed on the line (3) of cut on the which acts when the ring tongue (4) is manually swung entity on the rivet (5) that fixes the ring tongue to the body (1) of the cover. The lid (1) can adopt the circular configuration of Figure 1, the rectangular configuration with rounded vertices of Figure 3, or any other conventional configuration in this type of containers, such as an elliptical configuration, which is normally also provided with embossments. (7) reinforce your \ hbox {structure.}
Por tanto, a partir de esta estructura básica y convencional, ya según la invención, la línea (3) de corte, en su zona en la que se enfrenta a la lengüeta (4) anular, sufre una variación en su trayectoria, definiendo un segmento (8) de rotura en una forma de arco de circunferencia, que tiene un centro (9) de curvatura dispuesto en correspondencia con el centro del remache (5), tal como puede verse en particular en la figura 2, de manera que el punto medio de este segmento (8) de rotura arqueado se sitúa en correspondencia con el punto (10) teórico previsto para hacer funcionar el vértice (6) de perforación de la lengüeta (4) anular cuando ésta se sitúa correctamente en el contexto de la tapa (1).Therefore, from this basic structure and conventional, already according to the invention, the cutting line (3), in its area where the ring tongue (4) faces, suffers a variation in its trajectory, defining a segment (8) of breakage in a circle arc shape, which has a center (9) of curvature arranged in correspondence with the center of the rivet (5), as can be seen in particular in Figure 2, so that the midpoint of this arcuate break segment (8) is located in correspondence with the theoretical point (10) planned to make operate the piercing vertex (6) of the annular tongue (4) when it is correctly placed in the context of the lid (one).
Tal como se mencionó anteriormente, esto da como resultado que, tras un giro accidental de la lengüeta (4) anular, en cualquier momento a lo largo del proceso de manipulación del recipiente, su vértice (6) de perforación se mantiene perfectamente en su lugar enfrentado a la línea (3) de corte, específicamente a lo largo de este segmento (8) de rotura, garantizando así que las condiciones de arranque son óptimas.As mentioned earlier, this gives as result that, after an accidental rotation of the ring tongue (4), at any time throughout the process of handling the container, its drilling vertex (6) is perfectly maintained instead facing the cutting line (3), specifically length of this segment (8) of breakage, thus ensuring that boot conditions are optimal.
Tal como también se mencionó anteriormente, la amplitud de dicho segmento (8) de rotura con un centro (9) de curvatura que coincide con el eje del remache (5) puede estar comprendida entre 1º y 80º, siendo la amplitud de dicho arco preferiblemente de 20º, 10º en cada lado del punto (10) teórico previsto para hacer funcionar el vértice (6) de perforación de la lengüeta (4) anular cuando ésta se sitúa correctamente en el contexto de la tapa (1), y dicho segmento (8) de rotura se unirá al resto de la línea (3) de corte mediante inflexiones (11-11') dobles, de desviación y arqueadas, que facilitan el arranque de la tapa (1), impidiendo la existencia de curvas agudas en dicha línea (3) de corte que podrían afectar de manera negativa el arranque de la tapa.As also mentioned above, the amplitude of said break segment (8) with a center (9) of curvature that coincides with the axis of the rivet (5) may be between 1º and 80º, being the amplitude of said arc preferably of 20º, 10º on each side of the theoretical point (10) intended to operate the drilling vertex (6) of the tab (4) cancel when it is correctly positioned in the context of the cover (1), and said break segment (8) will join the rest of the cutting line (3) by inflections (11-11 ') double, deviation and arched, which facilitate the removal of the lid (1), preventing the existence of sharp curves in said cutting line (3) that could affect Negative way the lid starts.
