[0002] A disposable paper cup is a paper cup that is easy to carry and use. It is a common drinking tool in many households and public places. With the development of the times, people's environmental awareness is getting stronger and stronger. Conventional disposable water cups usually use recycled polyethylene, which will undergo cracking changes during the reprocessing process and produce many harmful compounds. It is easier to migrate into the water during use, which can easily cause environmental pollution. In addition, due to the material problem, the existing disposable paper cups have unsatisfactory heat insulation and can easily cause burns. Therefore, in view of the above situation, a degradable water-resistant cup and a production method thereof are proposed. Summary of the invention

The disc structure 101 is provided with a first opening 102 and a second opening 103, the first opening 102 is arc-shaped and is provided around the arc of the disc structure 101, the first opening 102 is provided at both ends, the first opening 102 enables the upper cup body 2 to communicate with the lower cup body 3, the second opening 103 is provided in the middle of the disc structure 101 and a cover sheet 104 is connected to the second opening 103, a cross scratch 105 is provided on the cover sheet 104, the cross scratch 105 enables the cover sheet 104 to be opened so as to achieve communication between the lower cup body 3 and the upper cup body 2, and the disc structure 101 is used for drinking tea or making tea and other similar occasions; The folding portion 6 is foldable, and the unfolded shape of the folding portion 6 is a trapezoidal structure that is longer at the top and shorter at the bottom. A folding line 601 is provided on the folding portion 6, and the folding portion 6 forms a zigzag structure through the folding line 601 and is foldable; The upper surface of the handheld portion 7 is provided with a support block 701 and a gripping block 702. The support block 701 is an isosceles trapezoidal structure and is made of PBAT material. The gripping block 702 is hemispherical and covers the support block 701. The gripping block 702 is made of gelatin. The support block is used for support, so it is a hard material and increases the hardness of the handheld portion. The gripping block is used for holding, so it is a soft material and increases the hand feel and anti-slip property when holding.

When the tea leaves are bagged, the bagged tea leaves are inserted into the cross scratches 105, which will cause the cover sheet 104 to limit the bagged tea leaves, making it difficult for the bagged tea leaves to slide out, thereby preventing the tea bag from falling and splashing the tea on the drinker's face when drinking tea. When drinking, the drinker picks up the water cup body 1 through the hand-held part 7 to drink. The support block 701 and the grip block 702 on the hand-held part 7 work together to prevent the drinker from getting hot when picking up the water cup body and to increase the drinker's hand feel and anti-slip performance when picking up the cup.
