Description

Technical Field

[0001] The utility model relates to the technical field of paper cover application, in particular to a novel air-deflation and leakage-proof paper cover. Background Art

[0002] Common paper covers are usually made of double-piece or single-piece paper, or paper covers molded from pulp. When this type of paper cover is used with a paper cup, the outer edge of the paper cover is used to hold the curled edge of the paper cup. However, this fastening method causes the joint between the paper cover and the paper cup to become loose when affected by the temperature and water vapor of the beverage in the cup, thereby creating a gap and causing beverage leakage. In addition, the traditional paper cover structure does not clamp the curled edge of the paper cup from both the inner and outer sides of the curled edge of the paper cup, which makes it easy for the beverage to leak along the cup mouth, and there is also a risk of the cover coming off, resulting in the undesirable phenomenon of beverage spilling. Utility Model Content
