The present invention provides a heat-insulating paper cup, which comprising: a cup body, which consists of a conical cylindrical wall, a cup bottom and a cup rim; a glued heat-insulating tube, with its inner wall sleeved onto the exterior of the conical cylindrical wall of the cup body; and the heat-insulating tube and the conical cylindrical wall of the cup body are adhered securely by glue; the heat-insulating tube is of conical cylindrical shape and mated with the conical cylindrical wall; moreover, the external wall of the heat-insulating tube is designed with a smooth surface; multiple raised lines, protruded at interval onto the inner wall of the heat-insulating tube, and mated with the conical cylindrical wall of the cup body; multiple hollow ducts, set into the heat-insulating tube at interval in tune with the raised lines; with this design, the novel heat-insulating paper cup can facilitate the advertisement printing and fabrication with better applicability; the raised lines on the inner wall of the heat-insulating tube can support the ribs, thus enhancing the structural strength and robustness of the heat-insulating tube and avoiding squashing during manual holding.
