The inner side of the inner convex ring is set to be an annular cambered surface, and when the easy-open cover is torn, articles in the container are poured out or stretched into the container to take the articles, the inner side edge of the buffer pressing ring cannot be scratched.
As a still further preferable mode of the utility model, the inclination of the annular inclined plane is 60-80 degrees. The annular inclined plane is preferably 60-80 degrees, and the cover surface is guided by the annular inclined plane in the upward pulling process to deform less, so that the labor is saved.
Compared with the prior art, the utility model has the following advantages:
the metal easy-open cover with higher safety is provided with the annular guide surface at the inner side of the buffer pressing ring, when the cover surface is torn and pulled upwards, the annular guide surface plays a role in guiding the edge of the cover surface, and the edge of the cover surface can move upwards from the lower end of the buffer pressing ring along the annular guide surface and finally separate from the upper end of the buffer pressing ring, so that the pulling-up cover surface is more labor-saving, smoother and stable, the shaking of the container is avoided, and further the liquid in the container is prevented from being spilled due to the forced cover opening.
