Closing lid

Abstract

A closing lid disposed on the extreme pouring opening of a container (200) fitted with an external ring (210), which comprehends a one-piece body that includes a circular central region (110) that presents, on the internal surface, a circumferential groove (121) next to the perimeter, and the ring (120) disposed descendingly from the perimeter of the said circular central region (110), the said ring (120) which presents an upper projection (127) over the external surface of the circular central region (110), and the internal surface of the said ring (120) following the format of the circular central region (110), the said ring (120) which presents, from the circumferential groove (121), a descending projection where the circumferential rims are disposed, followed by a circumferential furrow (123) with a weakening line (1231), if following a descending surface (124) that presents, in the intermediary portion, an arrangement of rims (125) disposed, segmented, and interconnected to the internal region of the descending surface (124) through a flexible connection (1251), the external surface of the ring (120) presenting a catch (126) interconnected to the weakening line (1231).

Description

FIELD OF THE INVENTION[0001]This invention concerns a closing lid for metallic, plastic, and glass containers, preferably, for conditioning products with or without vacuum treatment. More specifically, it comprehends a closing lid consisting of a one-piece body with a circular central region and a ring disposed descendingly from the perimeter of the said circular central region aggregating the functions of closure, sealing, and violability indication, thus eliminating the need to use aluminum seals or the like, and ensuring the re-use of the lid after opening.BACKGROUND OF THE INVENTION[0002]The packaging has always been of fundamental importance for trade development. At first, it existed to contain, protect and make the transportation viable. Nowadays, new functions are incorporated and new roles are played: conserving, exposing, selling the product, and winning over consumers by means of visual communication are part of this new profile.[0003]Modern life requires practicability a...

AI Technical Summary

Benefits of technology

"The invention is a closing lid for food containers that has several technical effects. Firstly, it is made of a single piece with a circular center and a ring that serves as a seal and indicates if the container has been opened. Secondly, it eliminates the need for an aluminum seal to perfectly close the lid. Thirdly, it allows for multiple closings and continuous sealing, and can be reused for other purposes. Fourthly, it ensures the foodstuffs conditioned during consumption are conserved."

Problems solved by technology

The functionality of the closure of cans, which has been improving ever since, also interferes with the choice made by the consumer.

The research reveals that after new systems of opening appeared, the consumption of some canned goods has increased.

The tendency is to improve the closure of the packaging and to avoid the use of knives, scissors, and other objects to open the product, thus diminishing the risk of consumers' injuring themselves while handling the packaging.

Firstly, the conventional type closing lids of cans were of metal and opened by using a can opener, thus eliminating the possibility of re-using the container and generating points of rust harmful to the conditioning of foodstuffs.

Furthermore, the rim of the said seal made difficult the removal of the product and generated the accumulation of residues.

The lid through pressure adapts itself to the external string formed by the body of the can with the safety locks contracting in the act of closure and tending to return to the initial position, thus causing the locking.

When the lid is removed, the fragile connections are broken preventing the lid on the neck of the container to be replaced in its initial integrity.
