[0002] A cup is a container for people to hold liquids. It can be used to drink tea, water, beverages, etc. Because the cup is open, the liquid in the cup is easily contaminated by dust around it or easily spilled. Therefore, when it is placed for a long time or needs to be transported, it is often covered with a cup cover. The cup cover is provided with a drinking port and a sealing part. When drinking, there is no need to unscrew the cup cover. The sealing part can be opened to drink the liquid in the cup through the drinking port. Since the sealing part rotates on one side of the cup cover after opening, when the cup is tilted, the sealing part can easily hit the user's face. Therefore, a leak-proof cup cover is proposed to prevent the sealing part from hitting the user's face. Utility Model Content
