For the purpose of the above, the present invention is a paper cup cover structure comprising a cup body, which is made of paper, and has a flat cup edge on the outer edge of the outer cup mouth, and the outer edge of the cup edge has a flat surface; and a cup cover corresponding to the inner wall surface of the flat surface of the cup body, and an annular card groove is recessed, and a pushing portion is extended under the annular card slot to make the cup edge The ring card slot is combined.

In the above embodiment of the present invention, the edge of the cup is included in the outer end edge and an extension is provided on the lower ring.

In the above embodiment of the present invention, the edge of the cup and the extension portion thereof are formed by folding and pressing a bead formed on the periphery of the cup mouth.

In the above embodiment of the present creation, the pushing portion is slightly inverted outward in a barbed shape.

In the above embodiment of the present invention, the pushing portion is outwardly extended to be inclined in an outer shape.

In the above embodiment of the present invention, the inner loop of the pushing portion is provided with a plurality of ribs for abutting against the lower end edge of the cup edge.

In the above embodiment of the present invention, the top of the cup cover protrudes upwardly from the edge of the cup edge of the cup body, and a flange is formed by the flange inwardly inclined downward along the inner wall surface of the cup body. The recessed portion is in close contact with the inner wall surface of the cup body, and the flange is further provided with a lower groove, and the lower groove is provided with an abutting top portion, and the abutting top portion abuts against the cup edge.

In the above embodiment of the present invention, the top surface of the cup lid is inclined downward along the inner wall surface of the cup body, and the recess portion is in close contact with the inner wall surface of the cup body.

In the above embodiment of the present invention, the cup edge is formed by plastic molding or paper forming by frame molding or paper pressing.

In the above embodiment of the present creation, the cup can be in a downward state in the molding die, and the horizontal state is restored after being taken out.
