Description

TAPA DE CIERRE PARA UN RECIPIENTE DE FÁCIL APERTURA CLOSING LID FOR AN EASY TO OPEN CONTAINER
La presente invención se refiere a una tapa de cierre para un recipiente de fácil apertura. Más en concreto, la invención proporciona una tapa de cierre para un recipiente de los denominados habitualmente como abre-fácil y destinado a contener cualquier tipo de alimento envasado, siendo el recipiente del tipo de los que están conformados por un cuerpo metálico, en particular cilindrico, y una tapa de cierre inicialmente integral al recipiente cuya apertura se realiza por tracción de una anilla dispuesta en la cara vista de dicha tapa y fijada a la misma por un remache. The present invention relates to a closure cap for an easy-open container. More specifically, the invention provides a closing lid for a container of the so-called commonly easy-open and intended to contain any type of packaged food, the container being of the type that consists of a metal body, in particular cylindrical , and a closing lid initially integral to the container, the opening of which is carried out by pulling a ring arranged on the exposed face of said lid and fixed to it by a rivet.
Son bien conocidos los recipientes denominados comúnmente como“latas de conserva” equipados con un sistema de apertura abre-fácil. Estos sistemas de apertura abre-fácil usualmente consisten en una tapa unida al recipiente de forma separable gracias a una línea de corte prevista para su debilitamiento y que presenta en su cara vista una anilla de tracción que permite separar angularmente la tapa dejando al descubierto al menos parte del contenido de la misma. Containers commonly referred to as "canning cans" equipped with an easy-open system are well known. These easy-open opening systems usually consist of a lid that can be attached to the container in a detachable way thanks to a cut line designed to weaken it and that has a pull ring on its exposed face that allows the lid to be angularly separated, exposing at least part of the content of it.
Estas latas de conserva conocidas presentan ciertas desventajas asociadas al propio sistema de apertura. Por una parte, la necesidad de traccionar la anilla conlleva aplicar en primer lugar una fuerza para separar parcialmente dicha anilla de la superficie de la tapa y, en segundo lugar, una fuerza de tracción hacia arriba sobre la anilla que permita arrastrar con ella la propia tapa con el fin de separarla del cuerpo del envase. These known canning cans have certain disadvantages associated with the opening system itself. On the one hand, the need to pull the ring involves first applying a force to partially separate said ring from the surface of the cover and, secondly, an upward pulling force on the ring that allows it to be dragged with the ring itself. lid in order to separate it from the body of the container.
Con respecto al primer punto, a menudo es necesario el uso de alguna herramienta para realizar esta acción, ya que puede resultar difícil separar la anilla de la tapa a la vista de que dicho levantamiento se produce no sólo mediante una fuerza de palanca contra el remache que fija la anilla a la tapa, sino también contra el propio cuerpo de la lata. A menudo esta fuerza aplicada hace que la anilla se desprenda del remache, imposibilitando así la apertura del envase. En cuanto a la fuerza de tracción hacia arriba sobre la anilla, ésta depende no sólo de la resistencia de la línea de corte en la periferia de la zona de unión de la tapa al envase, sino también del diseño del propio remache, ya que la apertura de la tapa habitualmente se facilita por la fuerza de palanca que un extremo de la anilla en la zona del remache hace sobre el cuerpo de la lata, estando limitado por tanto el ángulo en que se tracciona de la anilla a aproximadamente 22Q. Regarding the first point, the use of some tool is often necessary to carry out this action, since it can be difficult to separate the ring from the cover, given that said lifting occurs not only by means of a lever force against the rivet. that fixes the ring to the lid, but also against the body of the can. Often this applied force causes the ring to detach from the rivet, thus making it impossible to open the container. As for the upward pulling force on the ring, it depends not only on the resistance of the cutting line at the periphery of the area where the lid is attached to the container, but also on the design of the rivet itself, since the Opening of the lid is usually facilitated by the levering force that one end of the ring in the area of the rivet makes on the body of the can, thus being limited to the angle in which the ring is pulled to approximately 22 Q.
La presente invención soluciona las desventajas antes citadas de las latas de conserva ya conocidas, proporcionando una tapa de cierre para un recipiente de los denominados habitualmente como abre-fácil destinado a contener cualquier tipo de alimento envasado donde esencialmente la especial conformación del remache que une la anilla de tracción a la tapa permite una fácil apertura con un mayor ángulo de levantamiento de la anilla y sin riesgo de desprendimiento de la misma. The present invention solves the aforementioned disadvantages of the canned cans already known, providing a closing lid for a container of the so-called commonly easy-open intended to contain any type of packaged food where essentially the special shape of the rivet that joins the cover pull ring allows easy opening with a greater angle of lifting of the ring and without risk of detachment.
Tal como se ha mencionado anteriormente, el recipiente es del tipo de los que están conformados por un cuerpo metálico, en particular cilindrico, y una tapa de cierre inicialmente integral al recipiente cuya apertura se realiza por tracción de una anilla dispuesta en la cara vista de dicha tapa y fijada a la misma por un remache. As mentioned above, the container is of the type made up of a metal body, in particular a cylindrical one, and a closing cover initially integral to the container, the opening of which is carried out by pulling a ring arranged on the exposed face of said lid and fixed to it by a rivet.
Así, la tapa de cierre de la presente invención es del tipo de las que presentan una anilla de tracción fijada a la tapa de un recipiente metálico mediante un remache. Dicha anilla de tracción tiene esencialmente forma de cuña redondeada en su extremo más ancho y trapezoidal en su extremo opuesto, uniéndose por este extremo trapezoidal a la tapa mediante un remache. Thus, the closure cap of the present invention is of the type with a pull ring attached to the lid of a metal container by means of a rivet. Said pull ring is essentially wedge-shaped rounded at its widest end and trapezoidal at its opposite end, being joined by this trapezoidal end to the cover by means of a rivet.
En este extremo trapezoidal, la anilla tiene una depresión también trapezoidal que presenta una línea de debilitamiento en forma de U que perimetra parcialmente el remache circular. También en este extremo, la anilla presenta una prolongación esencialmente triangular cuyo vértice define el punto de apoyo de la anilla contra la tapa para la apertura. At this trapezoidal end, the ring has a trapezoidal depression that also has a U-shaped line of weakness that partially surrounds the circular rivet. Also at this end, the ring has an essentially triangular extension whose vertex defines the point of support of the ring against the cover for opening.
Este diseño del conjunto de la anilla y el remache de la tapa de la invención permite una apertura con un ángulo de 29Q, sensiblemente mayor al que proporcionan las tapas abre-fácil del estado de la técnica, facilitando con ello la apertura del envase y evitando los inconvenientes anteriormente citados. This design of the ring and rivet assembly of the cover of the invention allows an opening with an angle of 29 Q , significantly greater than that They provide the easy-open lids of the state of the art, thereby facilitating the opening of the container and avoiding the aforementioned drawbacks.
A continuación, se describe la invención en base a una forma de realización de la misma y en referencia a las figuras adjuntas, en las cuales se muestra: Figura 1 : una vista superior de la tapa de cierre de la invención. Figura 2: detalle de la anilla de la tapa de la figura 1. Figura 3a: corte en sección de una tapa convencional por la zona de la anilla. Figura 3b: corte en sección de la figura 3a en estado de levantamiento de la anilla. Figura 4a: corte en sección según la línea A de la tapa de la figura 1 por la zona de la anilla y detalle de rebaje. In the following, the invention is described based on an embodiment thereof and with reference to the attached figures, in which it is shown: Figure 1: a top view of the closure cap of the invention. Figure 2: detail of the ring of the cover of figure 1. Figure 3a: sectional cut of a conventional cover in the area of the ring.

Figura 4b: corte en sección de la figura 4a en estado de levantamiento de la anilla. Figure 4b: sectional cut of figure 4a in the lifting state of the ring.
Como se observa en la figura 1 , la tapa de cierre (1 ) de la presente invención es del tipo de las que presentan una anilla de tracción (2) fijada a la tapa (1 ) de un recipiente metálico mediante un remache circular (3). As seen in Figure 1, the closure cap (1) of the present invention is of the type that has a pull ring (2) attached to the lid (1) of a metal container by means of a circular rivet (3 ).
En referencia a las figuras 1 y 2, esta anilla de tracción (2) tiene esencialmente forma de cuña redondeada en su extremo más ancho y trapezoidal en su extremo opuesto, uniéndose por este extremo trapezoidal a la tapa (1 ) mediante el remache (3). With reference to Figures 1 and 2, this pull ring (2) is essentially wedge-shaped rounded at its widest end and trapezoidal at its opposite end, being joined by this trapezoidal end to the cover (1) by means of the rivet (3 ).
En este extremo trapezoidal, la anilla (2) presenta una depresión también trapezoidal que incluye una línea de debilitamiento en forma de U (4) perimetrando parcialmente el remache (3). También en este extremo, la anilla presenta una prolongación esencialmente triangular (5) cuyo vértice define el punto de apoyo de la anilla contra la tapa para la apertura. En uso, durante el levantamiento de la anilla (2) y la separación de la tapa (1 ), la cooperación de la línea de debilitamiento (4), la prolongación (5) y el remache (3) permite la apertura de la tapa. At this trapezoidal end, the ring (2) has a trapezoidal depression that includes a weakening line in the form of a U (4), partially surrounding the rivet (3). Also at this end, the ring has an essentially triangular extension (5) whose vertex defines the point of support of the ring against the cover for opening. In use, during the lifting of the ring (2) and the separation of the cover (1), the cooperation of the weakening line (4), the extension (5) and the rivet (3) allows the opening of the cover .
Como se observa en las figuras 3a y 3b, el ángulo de apertura de la anilla está determinado por el diámetro (A) del remache (3) y por la distancia (B) desde el punto (10) donde termina la línea de debilitamiento (4) hasta la punta de la anilla, que es la zona que ejerce la fuerza sobre dicha línea de debilitamiento para romper el metal. Cuando se ejerce entonces una fuerza hacia arriba sobre la anilla de tracción, una zona intermedia (C) entre el remache (3) y la punta de la anilla se deforma gracias a la línea de debilitamiento y a la geometría del conjunto. As seen in Figures 3a and 3b, the ring opening angle is determined by the diameter (A) of the rivet (3) and by the distance (B) from the point (10) where the line of weakening ends ( 4) to the tip of the ring, which is the area that exerts force on said line of weakness to break the metal. When an upward force is then exerted on the pull ring, an intermediate zone (C) between the rivet (3) and the tip of the ring is deformed thanks to the line of weakness and the geometry of the assembly.
En la figura 3b se observa que el ángulo que forma la tapa y la anilla levantada es de 22Q en una tapa convencional. Figure 3b shows that the angle between the cover and the raised ring is 22 Q in a conventional cover.
La tapa proporcionada por la invención y en particular el conjunto de la anilla (2) y el remache (3) permite una apertura mayor a una tapa convencional, tal como un ángulo de 29Q frente, a los 22Q de una tapa convencional, facilitando con ello la apertura del envase y disminuyendo la fuerza necesaria para ello. The cover provided by the invention and in particular the assembly of the ring (2) and the rivet (3) allows a larger opening to a conventional cover, such as an angle of 29 Q in front, than the 22 Q of a conventional cover, thereby facilitating the opening of the container and reducing the force necessary for it.
Para ello, en la tapa de la invención, la distancia (B’) desde el punto (10) donde termina la línea de debilitamiento (4) hasta la punta de la anilla se reduce, teniendo una longitud (B’) < (B), de forma que B’ = 0,66 B. For this, in the cover of the invention, the distance (B ') from the point (10) where the weakening line (4) ends to the tip of the ring is reduced, having a length (B') <(B ), so that B '= 0.66 B.
Así, tal como se muestra en las figuras 4a y 4b, con respecto a la longitud de la anilla (L) de la tapa de la invención, la distancia entre el final de la línea de debilitamiento (4) y la punta de la anilla es B’ = L/13,5. Thus, as shown in Figures 4a and 4b, with respect to the length of the ring (L) of the cap of the invention, the distance between the end of the line of weakness (4) and the tip of the ring is B '= L / 13.5.
En una realización preferente, esta distancia (B’) es de 2,75 mm. In a preferred embodiment, this distance (B ’) is 2.75 mm.
Por ejemplo, para conseguir esta mayor distancia (B’) en un ejemplo de realización se aumenta el diámetro (A) del remache (3). For example, in order to achieve this greater distance (B ’) in one embodiment, the diameter (A) of the rivet (3) is increased.
Además, la tapa de la invención presenta, en correspondencia con la prolongación esencialmente triangular (5) cuyo vértice define el punto de apoyo de la anilla contra la tapa, un rebaje cóncavo (6) que facilita el pivote del extremo de la anilla sobre la tapa con el fin de ayudar aún más a la apertura. En una realización preferente, dicho rebaje tiene radio de 0,7 mm. Furthermore, the cover of the invention has, in correspondence with the essentially triangular extension (5) whose vertex defines the point of support of the ring against the cover, a concave recess (6) that facilitates the pivoting of the end of the ring on the cover in order to further aid opening. In a preferred embodiment, said recess has a radius of 0.7 mm.
Igualmente, para facilitar la apertura, el extremo redondeado y opuesto a la zona del remache de la anilla de tracción (2) forma un ángulo de 174Q con respecto al plano de la superficie de la tapa, lo que permite que se alcancen 29Q en el extremo de la punta de la anilla con mayor rapidez. Likewise, to facilitate opening, the rounded end opposite the area of the rivet of the pull ring (2) forms an angle of 174 Q with respect to the plane of the surface of the cover, allowing 29 Q to be reached at the tip end of the ring faster.
