A bowl cover, a bowl and a die cutting rule
By designing an arc-shaped cut on the bottom of the food bowl lid and setting a release layer locally, the problem of the tongue tip bending at the base is solved, improving the product's appearance and peeling performance, and making it suitable for automated packaging.

AI Technical Summary
The base of the tongue of existing food bowl lids is prone to bending and curling after die-cutting, affecting the product appearance and automated packaging process, and the peeling performance is poor.
The second cut of the lower cover is designed as an arc that is recessed towards the center of the bowl lid, and the maximum arc height distance from the midpoint of the outer edge of the first tongue to the second cut is greater than the vertical distance. Combined with the local setting of the release layer, the obtuse angle area at the root of the tongue is ensured, which enhances the resistance to deformation and the ease of peeling.
It effectively prevents the base of the tongue from warping, improves product appearance quality and production stability, and ensures peeling performance to meet the needs of automated packaging.
