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

A pulp-molded paper lid for a beverage cup and a method of manufacturing the same are introduced. While the pulp-molded paper lid supports external pressure to accommodate the convex protruding ring of the cup body therein， by pre-applying the insertion force of the convex protruding ring， the elastic mechanism of the pulp-molded paper lid is formed by pulp molding. It is pre-compressed so as to compressively deform along the inner direction respectively opposite to the radial direction of the paper lid. By removing the external pressure， the movable support wall and the outermost side wall of the elastic generating mechanism apply elastic repulsive forces in two opposite directions by the elongation deformation occurring between them to clamp the two opposite sides of the convex protruding ring. do. The elastic generating mechanism is released from the pre-compression 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.
