An improved structure of paper cup, which comprising: a cup body and bottom; the cup body is designed with an annular side wall, and an outward folded arced cup edge is set on the ring edge at one end; the annular side wall is provided with an annular side wall mated with the annular side wall of the cup body far away from the cup edge to form holding space; the cup body and bottom form a holding space; particularly, an inflexed edge is formed at the annular side walls where the cup body is abutted with the cup bottom, thus reducing the height of the annular side wall for the mating of the cup body and bottom; when a large number of paper cups are stacked, the gap between cups could be reduced, thus increasing the storage amount and saving the storage and transportation cost.
