The seventh figure is a partial actuation diagram of the elastic opening of the cup cover of the present invention.

Referring to the second to fifth figures, the cup lid structure of the disposable beverage cup of the present invention has an inner concave surface 31 on the inner side surface and a snap fit on the lid edge 321 of the lid 3. The portion 32 is fastened to the cup flange 41 of a beverage cup 4, and the fastening portion 32 is provided with a content groove 323 for the cup flange 41 to be inserted into the receiving portion. The content groove 323 is respectively provided with a first fastening edge 322 and a second fastening edge 324 on both sides of the inner surface 320, wherein:

The lid 3 of the lid 3 is provided with at least one elastic notch 34. The two sides 341 and 342 of the elastic notch 34 have moderate expansion elasticity (as shown in FIG. 7 ), whereby the structure can be applied to different manufacturers. The use of the beverage cups produced by the fasteners.

The inner surface 320 of the above-mentioned content groove 323 is adhered with an annular leakage preventing layer 33, and the annular leakage preventing layer 33 is correspondingly disposed at a position where the cup flange 41 is in contact with the content groove 323, thereby the cup The mouth flange 41 is sealed to prevent leakage of the lid 3 and the beverage cup 4 The beverage leakage occurred after the combination.

The elastic notch 34 has a notch width W of less than 1 mm.

The elastic notch 34 has a notch depth H extending longitudinally upward from the edge of the cover edge 321 through the first fastening edge 322 but not extending to the position of the annular leakage preventing layer 33, so that the two sides of the elastic opening 34 can be maintained. 341, 342 have a moderate opening elasticity to accommodate the fastening of the beverage cup 4 produced by different manufacturers.

As shown in the sixth embodiment, the inner surface 320 of the content groove 323 is further recessed with a concave groove 325, and a part of the annular leakage preventing layer 33 is adhered into the concave groove 325, so as to be more deeply adhered thereto. The inner surface 320.

The annular leakage preventing layer 33 is adhered to the inner surface 320 of the content groove 323 of the cup cover 3, and the annular leakage preventing layer 33 protrudes from the inner surface 320.

The annular leakage preventing layer 33 is an elastic body to provide a tight force when the cup flange 41 is engaged.
