[0002] A packaging can is a container with a roughly uniform cross-sectional shape throughout the can body, a short neck, and an inner diameter slightly smaller than the inner neck of the can body, or no neck at all. It is a type of rigid packaging, made of high-strength packaging material and highly resistant to deformation. The packaging process involves filling, followed by sealing the can mouth. It can be used for transport packaging, outer packaging, commercial packaging, or inner packaging.

[0003] Patent authorization announcement number CN215591469U discloses a sealed tea packaging can, comprising: a can body, comprising a can body formed by one-time stretching, the upper end of the can body being contracted inward, the upper end of the can body opening being blanked and stretched to form a convex rim, the open end of the rim being curled inward to form a buckle; a cover, detachably mounted on the can body, comprising an outer cover, the outer cover comprising a top plate, the outer circumference of the top plate extending toward the can body to form a cover wall, a boss-shaped inner cover fixed to the inner surface of the top plate on one side of the top plate proximal to the can body, a gap being formed between the inner cover and the cover wall, and the rim being interference-fitted with the cover. The sealed tea packaging can provided by this utility model is reusable and has excellent sealing performance.

[0004] However, the above technical solution has the following shortcomings: although the interference fit between the convex edge of the can mouth and the cover can better ensure the sealing between the two, it requires a lot of force to open the cover, resulting in a poor user experience.
