The cooling cup for a drink is composed of a cup body(10) having a handle(11), outer and inner cups(12,13) doubly molded, and a combining hole(14) perforated at the lower end of the outer cup; a heat insulating material filled into a space between the outer and inner cups of the cup body; a refrigerant body(30) having a refrigerant cylinder(32) filled with a refrigerant and placed on the bottom side of the inner cup of the cup body to cool down the beverage contained in the inner cup; an upper cover(40) settled on the upper end of the cup body, closed up by a sealing ring(41), and provided with a hole(42) bored at one side; and a lower cover(50) fitted to the lower side of the cup body and thread-joined to the combining hole perforated at the lower end of the outer cup. |
