[0025] Example: A plastic-free biodegradable film-wrapped paper cup, such as Figures 1-4 As shown, the device includes an outer paper cup 1 and an inner paper cup 2 located inside the outer paper cup 1. The outer paper cup 1 includes a vertical groove 6, a connecting groove 12 fixedly disposed at one end of the vertical groove 6, and a holding groove 5 for holding wastewater. The vertical groove 6 is used to guide the wastewater, and the connecting groove 12 is used to connect the vertical groove 6 and the holding groove 5. The inner paper cup 2 is located inside the outer paper cup 1, and the upper ends of the inner paper cup 2 and the outer paper cup 1 are flush. The mouths of the two paper cups are connected by the paper cup material, making it convenient for users to drink water. At the same time, both the outer paper cup 1 and the inner paper cup 2 are wrapped with a plastic-free biodegradable film. The inner paper cup 2 is provided with a hole in its upper half. Hole 3: If the user does not pay attention to the water flow rate when filling the cup, and the water level reaches hole 3, the water in the cup will flow out through hole 3. A vertical groove 6 is provided, and the vertical groove 6 is connected to hole 3 via a guide device. This allows the water flowing out of hole 3 to flow into the vertical groove 6 through the guide device. Simultaneously, the vertical groove 6 is fixedly connected to the connecting groove 12, allowing the water in the vertical groove 6 to flow into the connecting groove 12. The connecting groove 12 is used to connect the vertical groove 6 to the holding tank 5, thus ensuring that the water in the inner paper cup 2 does not overflow, and preventing the user from being scalded when using the paper cup.

[0026] like Figures 1-4As shown, at least three holes 3 are provided on the inner side of the inner paper cup 2. The holes 3 are all located on the half side of the inner paper cup 2, in the upper half of the inner paper cup 2. At least three guide grooves 4 are fixedly installed on the outer wall of the inner paper cup 2. The guide grooves 4 are connected to the holes 3. By providing at least three holes 3 on the inner side of the inner paper cup 2, if the user does not pay attention to the water flow rate when filling the cup, and the water level reaches the hole 3, the water in the cup will flow out through the hole 3. Since the holes 3 are all located on the half side of the inner paper cup 2, they will not affect the user's use. By providing guide grooves 4 and connecting them to the holes 3, the water flowing out of the holes 3 flows to the guide grooves 4, thereby ensuring that the water level of the inner paper cup 2 is not higher than the holes 3, so that the user will not be scalded by the overflowing water.

[0027] like Figures 1-4 As shown, the guide groove 4 is fixedly connected to the vertical groove 6. The guide groove 4 is located at the end of the vertical groove 6 away from the connecting groove 12. A base 9 is fixedly installed at the bottom of the outer paper cup 1. The base 9 is made of rigid material and is higher than the holding groove 5. By setting the guide groove 4 to be fixedly connected to the vertical groove 6, the water flowing out of the hole 3 flows through the guide groove 4 to the vertical groove 6. At the same time, by setting the base 9 to be made of rigid material, it is ensured that the outer paper cup 1 can remain stable when placed and will not tip over, making it easier for users to use. At the same time, the base 9 is higher than the holding groove 5, so that the holding groove 5 will not affect the contact between the base 9 and the placing surface, further ensuring the stability of the paper cup.

[0028] like Figures 1-4 As shown, guide plates 8 are fixedly installed on both sides of the vertical groove 6 and the connecting groove 12. One side of the guide plate 8 abuts against the outer side of the inner paper cup 2. The outer paper cup 1 has a cavity 11 inside, which is used to place the inner paper cup 2. By fixing guide plates 8 on both sides of the vertical groove 6 and the connecting groove 12, and abutting the outer side of the inner paper cup 2, the water flowing out of the hole 3 will flow along the vertical groove 6 and the connecting groove 12. Due to the obstruction of the guide plate 8, the water will not flow to the outside of the vertical groove 6 and the connecting groove 12, which further ensures the drying of the paper cup and the flow of wastewater into the holding tank 5. By setting the cavity 11, the inner paper cup 2 is easy to place and the vertical groove 6 is easy to connect with the guide groove 4 and the connecting groove 12.

[0029] Working principle: When the water level is higher than the hole 3, water will flow out from the hole 3. The guide groove 4 is connected to the hole 3, so that the water flowing out of the hole 3 flows into the guide groove 4, thus ensuring that the water level of the inner paper cup 2 is not higher than the hole 3, so that the user will not be scalded by the overflowing water. The guide groove 4 is fixedly connected to the vertical groove 6, so that the water flowing out of the hole 3 flows into the vertical groove 6 through the guide groove 4. At the same time, the vertical groove 6 is fixedly connected to the connecting groove 12, so that the water in the vertical groove 6 flows into the connecting groove 12, and then into the holding groove 5, thus ensuring that the water in the inner paper cup 2 will not overflow, so that the user will not be scalded when using the paper cup. At the same time, by setting the bottom 9 to be made of rigid material, it ensures that the outer paper cup 1 can remain stable when placed and will not tip over, making it easier for the user to use. In addition, the bottom 9 is higher than the holding groove 5, so that the holding groove 5 will not affect the contact between the bottom 9 and the placement surface, further ensuring the stability of the paper cup placement.
