Abstract

The invention relates to a tin of the type in which the body (1) thereof comprises: a leak-tight lid (3) which is removed upon opening and an upper removable cover (6) which can be used to re-seal the body (1) if the tin has been opened and the lid (3) removed, but all of the contents therein have not been consumed. The inventive tin is characterised in that it comprises a flat elastic ring (8), made for example from rubber, which is considerably wide and which has a diameter that is substantially smaller than that of the body (1) of the tin. Said ring acts as a bridge between the body (1) and the cover (6); mechanically stabilising said elements and providing a seal between same.

Description

LATA DE CONSERVAS PERFECCIONADA CONSERVED CAN OF PERFECTED
D E S C R I P C I Ó ND E S C R I P C I Ó N
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a una lata de conservas, del tipo de las que incorporan una sobretapa desmontable, inicialmente inoperante, que tras la apertura de la lata permite restablecer el cierre de la misma, cuando el consumo de su contenido no se realiza de una sola vez.The present invention relates to a can of canned food, of the type that incorporates a removable, initially inoperative, overlay that, after opening the can, allows the closure of the can to be restored, when the consumption of its contents is not made of a once.
El objeto de la invención es conseguir que las condiciones de cierre estanco primitivas se restablezcan tras la apertura inicial de la lata.The object of the invention is to ensure that the primitive sealing conditions are restored after the initial opening of the can.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido las latas de conserva están estructuradas mediante un cuerpo que en unos casos es prismático-rectangular, en otros cilindrico y en otros de planta elíptica, que al menos en correspondencia con una de sus bases incorpora un reborde perimetral con una doble función, por un lado permitir el cierre estanco de la lata y por otro facilitar su posterior apertura cuando ésta se lleva a cabo con un abrelatas.As it is known, the canned cans are structured by a body that in some cases is prismatic-rectangular, in others cylindrical and in others elliptical, which at least in correspondence with one of its bases incorporates a perimeter flange with a double function, on the one hand, allow the sealed closure of the can and on the other, facilitate its later opening when it is carried out with a can opener.
El sistema clásico de apertura mediante abrelatas está tendiendo a desaparecer, sustituido por el comúnmente denominado "abre-fácil" consistente en establecer sobre la base de apertura de la lata una línea de debilitamiento perimetral que permite un fácil rasgado del material constitutivo de dicha base con la colaboración de una anilla que actúa simultáneamente como medio iniciador del rasgado, mediante basculación, y como medio de tracción para completar dicho rasgado.The classic opening system by means of can openers is tending to disappear, replaced by the commonly called "easy-opening" consisting of establishing a perimeter weakening line on the base of the can that allows easy tearing of the constituent material of said base with the collaboration of a ring that acts simultaneously as a tearing initiator, by tilting, and as a means of traction to complete said tearing.
Por otro lado y como es evidente cuanto mayor es la capacidad de la lata menor es la incidencia de los costos de envasado en el precio final del producto, por lo que es habitual la presencia en el mercado de latas de conservas con una capacidad superior a lo que podría considerarse una dosis de consumo, latas cuyo problema fundamental se centra en mantener una situación de cierre adecuada, una vez que se ha iniciado el consumo de su contenido.On the other hand, and as is evident, the greater the capacity of the can, the lower the incidence of packaging costs in the final price of the product, which is why the presence of canned cans with a capacity greater than what could be considered a dose of consumption, cans whose fundamental problem is focused on maintaining an adequate closing situation, once the consumption of its contents has begun.
En este sentido son conocidas latas de conserva que, a partir de la estructuración convencional y citada de cualquier lata de este tipo, incorporan una sobretapa físicamente independiente de la lata propiamente dicha, que tras la apertura de la misma y eliminación de la base correspondiente, permite restablecer la situación de cierre acoplándose a la embocadura de la lata y contando a tal efecto con un faldón perimetral que se solapa parcial y exteriormente a la pared lateral del cuerpo de la lata.In this sense, canned cans are known which, from the conventional and cited structuring of any such can, incorporate an overcap physically independent of the can itself, which after opening it and eliminating the corresponding base, it allows to restore the closing situation by coupling to the mouth of the can and counting for this purpose with a perimeter skirt that partially and externally overlaps the side wall of the can body.
Esta solución, si bien resulta aceptable, no asegura la debida estanqueidad en el cierre de la lata, por lo que resulta inviable cuando se trata de productos delicados.This solution, although acceptable, does not ensure proper tightness in the closure of the can, so it is unfeasible when it comes to delicate products.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La lata de conservas que la invención propone ha sido perfeccionada en orden a resolver de forma plenamente satisfactoria la problemática anteriormente expuesta, asegurando un cierre absolutamente estanco de la lata, una vez que se ha producido la apertura inicial de la misma, situación de cierre estanco que se mantiene indefinidamente con independencia de las veces que sea manipulada la sobretapa.The can of cans that the invention proposes has been perfected in order to solve in a fully satisfactory manner the above-mentioned problem, ensuring an absolutely tight closure of the can, once the initial opening of the can has occurred, a situation of tight closing that remains indefinitely regardless of the times manipulated the overcap.
Para ello y de forma más concreta dicha lata, partiendo de la estructuración básica y convencional anteriormente citada, es decir de la participación en la misma de una sobretapa utilizable tras la apertura inicial de la misma, centra sus características en la incorporación de un anillo elástico y plano, debidamente infradimensionado con respecto al perímetro de la lata como para que en situación de montaje resulte fuertemente presionado contra la misma, y de anchura a su vez adecuada para solaparse conjuntamente al faldón lateral de la sobretapa y a la pared lateral del cuerpo de la lata, de manera que el anillo elástico actúa como puente entre ambos elementos, que además de estabilizarlos firmemente, hermetiza la ranura de unión entre ellos.For this purpose and more specifically, said can, based on the basic and conventional structuring mentioned above, that is to say, the participation in it of a usable overcap after the initial opening of the same, focuses its characteristics on the incorporation of an elastic ring and flat, duly under-sized with respect to the perimeter of the can so that in a situation of assembly it is strongly pressed against it, and of width in turn suitable for overlapping together the side skirt of the overcap and the side wall of the body of the can, so that the elastic ring acts as a bridge between both elements, which in addition to stabilizing them firmly, seals the joint groove between them.
DESCRIPCIÓN DE LOS DIBUJOSDESCRIPTION OF THE DRAWINGS
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 made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. In an illustrative and non-limiting manner, the following has been represented:
La figura 1.- Muestra un despieze en perspectiva de una lata de conservas realizada de acuerdo con los perfeccionamientos objeto de la presente invención.Figure 1 shows a perspective breath of a can of canned food made in accordance with the improvements object of the present invention.

La figura 3.- Muestra, finalmente, un detalle parcial en sección diametral de la lata en situación de cierre, tras la apertura inicial de la misma.Figure 2.- Shows, also according to a perspective view, the same assembly of the previous figure, duly assembled. Figure 3.- It shows, finally, a partial detail in diametral section of the can in a closed situation, after its initial opening.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como la lata de conservas que la invención propone está constituida, como es convencional, a partir de un cuerpo (1) , que en el ejemplo de realización práctica representado en las figuras adopta una configuración cilindrica, pero que podría adoptar cualquier otra configuración, como por ejemplo una configuración prismática, sin que ello afecte a la esencia de la invención, cuerpo (1) dotado a nivel de su base superior de un reborde perimetral (2) a través del que, mediante agrafado, se fija al cuerpo (1) la tapa de cierre (3) determinante de una perfecta hermeticidad para el interior de la lata, tapa (3) que pude ser indistintamente eliminable de forma clásica, con un abrelatas, o que como en el ejemplo de realización práctica de las figuras puede estar dotada de una línea de debilitamiento (4) , obtenida por troquelado, a través de la que la tapa (3) es desgarrable con la colaboración de la clásica anilla (5) , sin que tampoco el sistema de apertura utilizado afecte a la esencia de la invención.In view of the aforementioned figures, it can be seen how the can of cans that the invention proposes is constituted, as is conventional, from a body (1), which in the example of practical embodiment represented in the figures adopts a cylindrical configuration, but that it could adopt any other configuration, such as a prismatic configuration, without affecting the essence of the invention, body (1) provided at the level of its upper base with a perimeter flange (2) through which, by attached, the closing lid (3) determining a perfect tightness for the inside of the can, lid (3) that can be indistinctly removable in a classical way, with a can opener, or which as in the case is attached to the body (1) An example of a practical embodiment of the figures can be provided with a weakening line (4), obtained by die-cutting, through which the cover (3) is tear-off with the collaboration of the classic ring (5), s in that the opening system used does not affect the essence of the invention.
Como también es convencional la lata propiamente dicha (1-3) se complementa con una sobretapa desmontableAs is conventional, the can itself (1-3) is complemented by a removable overcap
(6) materializada en una especia de cazoleta acoplable a la extremidad superior de cuerpo (1) a cuya pared lateral se solapa parcialmente mediante un faldón perimetral (7) , de manera que una vez eliminada la tapa (3) , mediante corte o rasgado, la sobretapa (6) permite restablecer la situación de cierre para la lata.(6) materialized in a spice of cup attachable to the upper body end (1) whose side wall partially overlaps by means of a perimeter skirt (7), so that once the cover (3) is removed, by cutting or tearing , the overcap (6) allows to restore the closing situation for the can.
Pues bien, a partir de esta estructuración básica y convencional, la lata que se preconiza incorpora además un anillo plano (8) , de un material elástico, como por ejemplo goma, de considerable anchura y de diámetro acusadamente infradimensionado con respecto al diámetro del cuerpo (1) , para que en el montaje del anillo (8) sobre este último se produzca una notable deformación de dicho anillo, que asegura, además de una perfecta estabilidad posicional con el mismo, unas óptimas condiciones de cierre estanco.Well, from this basic structuring and conventional, the can that is recommended also incorporates a flat ring (8), of an elastic material, such as rubber, of considerable width and of a markedly under-sized diameter with respect to the diameter of the body (1), so that in the assembly of the ring (8) on the latter there is a notable deformation of said ring, which ensures, in addition to a perfect positional stability therewith, optimal sealing conditions.
Este anillo está destinado a afectar simultáneamente al faldón perimetral (7) de la sobretapa (6) y parcial o totalmente a la pared lateral del cuerpo (1) , tal como se observa en la sección de la figura (3) , de manera que no solo inmoviliza la sobretapa (6) con respecto al cuerpo (1) de la lata, sino que además, al quedar fuertemente presionado contra ambos elementos, asegura un cierre estanco de la ranura o intersticio (9) de unión entre ellos . This ring is intended to simultaneously affect the perimeter skirt (7) of the overcap (6) and partially or totally the side wall of the body (1), as seen in the section of figure (3), so that Not only does it immobilize the overcap (6) with respect to the body (1) of the can, but also, being strongly pressed against both elements, ensures a tight seal of the groove or gap (9) of union between them.
