Ring-pull lid and ring-pull can thereof

Abstract

The invention relates to a ring-pull lid. The ring-pull lid comprises a lid body and a ring-pull. An opening piece formed in a nicking manner is arranged on the top face of the lid body from the center of the lid body to the edge of the lid body. The ring-pull is connected with the opening piece at the center position of the lid body. The ring-pull lid is characterized in that the opening piece comprises a tearing starting part, a tearing and separating part, a tearing part and a disengaging part which are sequentially distributed along the center of the lid body towards the edge of the lid body, and a thickness difference exists between the adjacent parts. Compared with the prior art, the ring-pull lid has the beneficial effects that the opening piece on the ring-pull lid is designed to be provided with the tearing starting part, the tearing and separating part, transitional parts and the disengaging part all of which have thickness differences, the purpose of lifting the opening piece most conveniently and quickly with less labor is achieved, the opening piece can be prevented from being pulled broken, and the problem that the opening piece flies off when the opening piece is torn quickly and other problems can be prevented. The invention further provides a ring-pull can.

Description

technical field [0001] The invention relates to the technical field of pop can processing, in particular to a pop-top lid and a pop-top can. Background technique [0002] As a packaging can for beverages, pop cans are widely used because of their small size, easy portability, and strong freshness retention. [0003] Existing pop cans generally include a tank body and a pull-out lid arranged on the top of the tank body. see figure 1 , which is a structural schematic diagram of an existing pull cover. The pull cover includes a cover body 01 and a pull ring 02. The top surface of the cover body 01 is provided with a ring of opening pieces 011 formed by thumb marks from the center of the cover body to the edge of the cover body. The pull ring 02 is on the cover body. The center is connected with the opening piece 011. When drinking, hook the pull ring 02 with your fingers, and pull the opening piece 011 along the notch, and then tear the opening piece 011 from the cover body...

AI Technical Summary

Problems solved by technology

[0004] The thickness of the current opening piece 011 is usually set as a two-stage difference structure that is thinner at the riveted part of the pull ring 02 and thicker at other positions. When the other positions are too thick, when the opening piece 011 is pulled, the pull ring 02 is easily separated from the riveting place and the opening. The opening piece 011 is detached, and the opening piece 011 cannot be effectively torn; or when the opening piece 011 is pulled, the opening piece 011 cannot be pulled apart according to the notch, so that the opening piece 011 is broken, so that the opening piece 11 cannot be effectively torn

And when other positions are too thin, it will affect the pressure bearing capacity of the opening piece 011, which will easily lead to the problem of leakage

In addition, if the surface area of ​​the existing opening piece 011 is set too large, the occurrence of the above-mentioned problems will be exacerbated. Therefore, the existing opening piece 011 is usually set smaller, so that after the opening piece 011 is torn off, the cover surface is exposed. The opening of the can is also small, which also makes it extremely inconvenient for users to drink canned beverages
