Abstract

The invention provides a metal screw cap, a zip-top can and a manufacturing method of the metal screw cap, and relates to the technical field of packaging containers. The metal screw cap comprises a screw cap body, a channel used for liquid to flow out is defined by the inner wall of the screw cap body, the screw cap body comprises a threaded part, an arc-shaped part and an edge folding part, thearc-shaped part is provided with a plurality of arc-shaped sections connected end to end, at least two arc-shaped sections are different in radius, the threaded part is used for being in threaded sealing connection with a cap body, and the edge folding part is used for sealing of the edge folding part and a flanging of the can body in a coiled mode. The metal screw cap with the threaded part is arranged, so that the zip-top can can be sealed again after being opened, liquid in the zip-top can can be prevented from being polluted or wasted, when the arc-shaped sections are formed by the arc-shaped part of the metal screw cap by adopting a stamping mode or when the zip-top can is filled with the liquid with certain pressure, the metal screw cap can keep good stability, and therefore the yield of the zip-top can can be advantageously increased.

Description

technical field [0001] The invention relates to the technical field of packaging containers, in particular to a metal screw cap, a pop can and a method for manufacturing the metal screw cap. Background technique [0002] Due to the advantages of easy portability, safe use and high recycling value, cans are widely used in the packaging of liquid products such as beverages, beer, and water. [0003] In the prior art, pop-top cans include a can body and an easy-open lid. Flanges are provided on the body of the can, and crimps are provided on the easy-open lid. The flanging on the can body is pressed into the curl on the easy-open lid to form an interlocking structure. This interlocking structure is then compressed to complete the seam seal. [0004] However, the pop cans in the prior art cannot be reclosed after being opened, and when the liquid in the pop cans cannot be drunk in time, it is easy to be polluted or wasted. Contents of the invention [0005] Embodiments of th...
