PULP-MOLDED PAPER LID FOR BEVERAGE CUP AND METHOD FOR FABRICATING THE SAME

A pulp molded paper lid for beverage cups and a method of manufacturing the same are introduced. While the pulp-molded paper lid bears the external pressure therein to accommodate the convex protrusion ring of the cup body， by the pre-application of the insertion force of the convex protrusion ring， the generated elastic mechanism of the pulp-molded paper lid is pulp-molded. The paper is pre-compressed to be compressed and deformed along the inner direction， respectively， facing the radial direction of the lid. By removing the external pressure， the movable support wall and the outermost side wall of the elastic generating mechanism apply elastic repulsive force in two opposite directions by elongation deformation occurring between them to clamp and hold the two opposing sides of the convex protruding ring. do. The elastic generating mechanism is released from the precompression in order to apply a pre-applied elastic force along the radial direction in order to strengthen the clamp holding and avoid the technical problems of the prior art.
