Abstract:
The present invention relates to a paper pulp molded cup lid. In particular, when two cup lids are stacked, a cambered concave surface of a lower inclined annular side wall of an upper cup lid is fitted to a cambered outer wall of a cambered sealing portion of a lower cup lid, and by means of the cambered concave surface of an inner side surface of the lower inclined annular side wall being in surface contact with the cambered outer wall of the cambered sealing portion of the other cup lid, the two cup lids are in surface contact without creating an impression. Moreover, the contact surfaces herein are in cambered contact, which serves a guiding function during stacking, such that a plurality of cup lids are easily stacked in order, and are not prone to falling or moving radially.
