    摘要: A pulp molded cup lid includes a lid top portion, a transverse extension portion and a longitudinal extension portion. The transverse extension portion is connected to a lower side of an outer edge of the lid top portion and extends radially outward. The longitudinal extension portion is connected to an outer edge of the transverse extension portion and extends axially downward. The longitudinal extension portion is cylindrical. The pulp molded cup lid further includes an inner convex buckle disposed on an inner wall of the longitudinal extension portion. The inner convex buckle is integrally formed with the longitudinal extension portion. The inner convex buckle protrudes inward relative to the inner wall of the longitudinal extension portion. An outer wall of the longitudinal extension portion defines a rolling groove. The rolling groove is configured to further reduce an inner diameter of the inner convex buckle.
