Abstract

Sistema de cierre con precinto para envases de plástico, en los que una (o más) lengüetas desgarrables evidencian la apertura del envase. Este sistema perfeccionado permite el poder construir la tapa con salientes o agarres interiores y también con salientes o agarres exteriores. Sirven para que el exterior dificulte la apertura fraudulenta del envase y, al mismo tiempo, este sistema permite una apertura mucho más cómoda que con los modelos antiguos o actuales, que necesitan el uso de las dos manos para su apertura y con el presente sistema no es necesario.Closure system with seal for plastic containers, in which one (or more) tear-off tabs show the opening of the container. This improved system allows to be able to build the lid with protrusions or internal grips and also with protrusions or external grips. They serve to make the exterior difficult the fraudulent opening of the container and, at the same time, this system allows a much more comfortable opening than with the old or current models, which need the use of both hands for opening and with the present system not necessary.

Description

Sistema de cierre con precinto para envases de plástico.Closure system with seal for packaging plastic.

Object of the invention

La presente invención, para la que se solicita el registro como Patente de Invención, consiste, como su título indica, en un nuevo cierre con precinto para envases de plástico, del tipo de los empleados preferentemente para contener productos alimenticios y que incorporan una tapa de plástico que se acopla sobre la boca del envase para obtener el cierre de seguridad del mismo, presentando, además, como novedad un medio de apertura fácil para el usuario.The present invention, for which it is requested Registration as an Invention Patent, consists, as its title indicates, in a new closure with seal for plastic containers, of the type of employees preferably to contain products food and incorporating a plastic lid that fits over the mouth of the container to obtain the safety closure of the same, presenting, in addition, as a novelty an easy opening means for the user.

Background of the invention

Conocidísimos son los envases de plástico, preferentemente destinados a contener productos alimenticios, que están provistos de una tapa con unos pliegues periféricos que definen un alojamiento en el que se introduce la boca del envase, ejerciendo exteriormente la periferia de la tapa una presión sobre dicha boca con el fin de inmovilizarla sobre él.Well-known are plastic containers, preferably intended to contain food products, which they are provided with a cover with peripheral folds that define a housing in which the mouth of the container is introduced, exerting externally the periphery of the lid a pressure on said mouth in order to immobilize it on him.

Pero estos tipos elementales de tapa, presentan unos cierres de seguridad que, si bien son seguros, poseen unos sistemas de apertura difíciles, engorrosos e imperfectos que perjudican la practicidad de la tapa, llegando a estropear el envase y causando el sistema una incomodidad al usuario.But these elementary cover types present some safety locks that, although they are safe, have some difficult, cumbersome and imperfect opening systems that impair the practicality of the lid, causing damage to the packaging and causing the system an inconvenience to the user.

Description of the invention

Para solventar los problemas que ocasiona una apertura difícil, se ha ideado un sistema de cierre con precinto para los envases de plástico, objeto de la presente invención, que presenta unas particularidades constructivas que permiten, no solamente un cierre de seguridad, sino también observar, según la posición del cierre si el envase ha sido abierto o manipulado para tal fin. Pero, también y de forma preferente aporta un sistema de apertura, rápido y sencillo, dentro de su capacidad de cierre de seguridad, que aporta una ventaja importante respecto a los cierres existentes en el mercado.To solve the problems caused by a difficult opening, a closure system with seal has been devised for plastic containers, object of the present invention, which it presents constructive peculiarities that allow, not only a safety lock, but also observe, according to the closing position if the container has been opened or handled to such end But, also and preferably provides a system of opening, fast and simple, within its closing capacity of security, which provides an important advantage over closures existing in the market.

Esta propiedad de sistema de cierre con precinto consiste en que la lengüeta desgarrable que evidencia la apertura del envase, no queda enganchada a la tapa, sino que sólo sirve para que al desgarrarla haya un espacio por donde poner los dedos para levantar la tapa.This property closing system with seal is that the tear-off tongue that evidences the opening of the container, it is not hooked to the lid, but only serves so that when tearing it there is a space to put your fingers To lift the lid.

Description of the drawings

Este sistema perfeccionado permite el poder construir la tapa (1) con salientes o agarres interiores (9) y también con salientes o agarres exteriores (7), que en el caso del dibujo sirven para que el saliente exterior (7) dificulte la apertura fraudulenta del envase.This perfected system allows power build the cover (1) with protrusions or inner grips (9) and also with projections or external grips (7), which in the case of drawing serve to make the outer projection (7) difficult the fraudulent opening of the container.

El cuerpo (2) del envase tiene un saliente (5) que se acopla al saliente (4) de la tapa en todo su perímetro, exceptuando los dos o más enganches (6) que entran en la ranura (10), de la lengüeta desgarrable. Estos enganches (6), son los que impiden la apertura del envase sin el previo desgarro de la lengüeta (11) siguiendo las zonas debilitadas (8).The body (2) of the container has a projection (5) which attaches to the projection (4) of the cover in all its perimeter, except for the two or more hooks (6) that enter the slot (10), of the tear tab. These hooks (6), are the ones that prevent the opening of the container without the previous tearing of the tab (11) following the weakened areas (8).

Con el número (10), se puede apreciar la zona de ajuste de la tapa con el envase, que da hermeticidad al envase.With the number (10), you can see the area of adjustment of the lid with the container, which gives tightness to the container.

Este sistema, al poder tener los salientes interiores (9) o salientes exteriores (7) o ambos tipos a la vez, permite una apertura del envase mucho más cómoda que con los modelos actuales, en que se necesita normalmente del uso de las dos manos, para proceder a la apertura una vez rotas las lengüetas del precinto.This system, being able to have the projections interior (9) or exterior projections (7) or both types at the same time, it allows a much more comfortable opening of the container than with current models, in which the use of the two is normally required hands, to proceed to the opening once broken the tabs of the seal.
