1. A sunken-type cup lid, for covering on a cup mouth of a cup body storing a liquid, which is made by using a wet pulp-molding technique to thermally compress a paper pulp in a way of integrally shaping three-dimensional overall sizes of the entire sunken-type cup lid, comprising:
a covering panel;
a leaning-on portion, formed around an outermost perimeter of the covering panel and having an outer peripheral sidewall downwardly extended to be tightly fitted onto an inner circumferential sidewall of the cup body in a tight-fit manner;
an outlet, formed within the covering panel;
a drinking spout, disposed on the covering panel and liquid-communicated with the outlet; and
a camber-holding portion, formed around an upper section of the leaning-on portion and outwardly extended to downwardly and tightly fit overneath the cup mouth; and
wherein the covering panel forms thereon a dome structure, with an upper convex-curved surface, which is upwardly cambered in a specific radian from a bottom of the sunken-type cup lid, to be in a manner that the camber-holding portion, the leaning-on portion and the upper convex-curved surface of the covering panel commonly delimit a sunken chamber with a storing space for storing the liquid overflowing out of the outlet, and the upper convex-curved surface forms thereon an uppermost apex and a plurality of low apexes, and the plurality of low apexes that are located along the outermost perimeter of the covering panel are integrally connected with a lowest section of the leaning-on portion, to respectively delimit a plurality of U-shaped cross-sectional bend portions, wherein an upper section of the drinking spout is formed with a drinking aperture which is located higher than the camber-holding portion, and an outer peripheral sidewall of the drinking spout is downwardly incline-extended to integrally intersect with the upper convex-curved surface of the covering panel, in a way of forming an intersectional boundary, with an obtuse angle, on a bottom of the outer peripheral sidewall of the drinking spout.
