Description

Technical Field

[0001] The utility model relates to the technical field of cup covers, in particular to a leak-proof one-piece cup cover for a disposable beverage cup. Background Art

[0002] In the fast-paced modern life, disposable beverage cups are widely used due to their convenience and hygiene, especially in the catering industry. However, behind this convenience, there is also a long-standing problem that has not been effectively solved - liquid leakage. When consumers carry beverages to move or drink, liquid leakage often occurs due to imperfect cup design or poor sealing of the cup lid, which not only brings inconvenience to consumers, but also increases the cleaning and maintenance costs of merchants.

[0003] Traditional disposable beverage cups usually adopt a split cup lid design, that is, the cup lid and the cup body are two independent parts, connected by a simple screw or snap method. Although this design meets the basic sealing requirements to a certain extent, it has many shortcomings in actual use. First, since there are often tiny gaps at the connection between the cup lid and the cup body, these gaps are easy to expand when the cup is tilted or impacted by external forces, causing liquid leakage. Secondly, the sealing performance of the split cup lid will gradually decrease after multiple openings and closings, especially in high temperature or humid environments, the aging of the material will accelerate this process. Finally, the traditional cup lid design often only focuses on sealing and ignores the convenience and comfort of user use, such as requiring too much force or complex operations when opening or closing, which may be a challenge for children or people with insufficient hand strength.
