Abstract
An improved cup structure includes a cup body having an inner cup and an outer cup, with a space disposed between the inner cup and the outer cup. In the cup body, bottoms of the inner and outer cups are connected by an extension rod having an ornament; one end of the extension rod is adhered to an outer bottom of the inner cup and placed in the outer cup with the inner cup. Edges of the inner and outer cup are melted together, and glue is filled from an aperture at the bottom at the outer cup to secure the other end of the extension rod and the ornament within the space.
