Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a beer beverage can with a pull ring cover. Background Art

[0002] In beer or beverage packaging, metal cans are used more and more frequently because they are not easy to break, easy to transport, and will not deteriorate due to light, compared to glass bottles. Metal packaging cans mainly include aluminum cans and iron cans. According to the application of existing technologies, aluminum cans have better sealing properties and can effectively prevent the entry of outside air, better protecting the freshness and taste of beer or beverages; at the same time, aluminum cans are relatively light and easier to store and place. The advantages of iron cans are that they are sturdy and not easy to deform, and have good thermal resistance. The disadvantages are that they are heavy, have high transportation pressure, have poor sealing properties, have poor oxygen isolation properties, are easy to rust, and affect the freshness of beer. At the same time, iron cans are inconvenient to open.

[0003] Therefore, it is necessary to develop a beer beverage packaging that can combine the advantages of aluminum cans and iron cans, which is strong and does not deform, can be well sealed and preserved, and is easy to use. Utility Model Content
