The utility model is further configured as follows: the top of the cover is also provided with a ventilation hole connecting the inside and outside of the cup.

By adopting the above technical solution, the hot drink inside the cup will cause the inner space to expand outward, affecting the seal between the cup cover and the cup body, and the increased ventilation holes can connect the inside and outside of the cup body, and discharge the expanded air inside the cup body come out.

The utility model is further configured as follows: the lower edge of the straight side is provided with a circle of outer edges inclined outward from the straight side.

By adopting the above technical solution, the outer edge is inclined outward, which facilitates the process of closing and opening the cup lid.

The utility model is further configured as follows: the environmental protection cup cover is integrally manufactured and formed from pulp.

By adopting the above technical solution and using pulp as the raw material, not only can the toxic substances volatilized by the material itself be avoided when used as a cup lid for hot drinks, but also there will be no degradation problem in the later stage of the cup lid, which is more environmentally friendly.

The utility model is further configured as follows: the inner surface of the environmental protection cup cover is provided with an anti-slip grid to increase the friction between it and the cup body.

By adopting the above-mentioned technical solution, the anti-slip grid can increase the frictional force between the cup cover and the curling of the cup body, and improve the connection strength between the two.

The utility model is further configured as follows: the liquid outlet is arranged as a waist-shaped hole and its waist is arranged in an arc toward the center of the top of the cover.

By adopting the above-mentioned technical scheme, when a person drinks the liquid in the cup body, the lip shape will be bent into an arc, and the liquid outlet will be arranged corresponding to this arc shape, which will help improve the sealing performance of the lip to the liquid outlet and prevent the liquid from flowing freely. Leakage from the outlet.
