Description

Technical Field

[0001] The utility model relates to the technical field of packaging containers, in particular to an easy-to-open cover structure that is convenient to use. Background Art

[0002] In order to facilitate people's daily life, nowadays there are convenience stores selling soda and so on in the streets and alleys. Since soda cans made of glass are expensive and difficult to recycle, few beverages are stored in glass soda cans. Since metal soda cans are often made of aluminum, metal cans can be easily recycled after people finish drinking the beverage, thus improving the utilization rate of materials.

[0003] The top of the metal can is often made of a pull-ring type easy-open cover. The working principle of the pull-ring type easy-open cover is to make an indentation at the opening of the can cover in advance. When the pull-ring is pulled, the indentation is broken by the force applied, thereby achieving the purpose of opening the metal can.

[0004] However, the existing easy-open lid structure is not convenient to open with little effort. When the elderly and children need to drink, it is difficult for them to open the lid by themselves and they need others or tools to open the lid. In addition, the existing easy-open lid structure is not convenient for secondary storage after opening. When there is no secondary storage method after opening, it is very easy for the material inside the metal can to mold. Therefore, an easy-open lid structure is proposed to solve the above problems.
