AI Technical Summary
The existing technology has difficulties in producing container lids made of natural fiber materials, especially due to the problems of uneven density and inconsistent mechanical properties, which lead to large differences in the thickness of the lids and are prone to cracking or excessive deformation.
A groove is provided at the protruding element of the container cover. By appropriately determining the size of the groove, the thickness of the cover is ensured to remain constant or reduce variability between different areas, thereby achieving uniform compaction of the material, uniform density and consistency of mechanical properties.
The uniformity of density and stability of mechanical properties of the container cover are achieved, cracking or excessive deformation of areas with too low density is avoided, and the overall quality of the cover is improved.
