PROBLEM TO BE SOLVED: To improve the dimensional precision and the strength, improve the heat-insulating effect, and at the same time, facilitate a classification disposal, and improve the design property by facilitating a printing on the surface by fitting an external cylinder made of paper on a container main body, being a plastic molded article on which protruding ribs are provided. SOLUTION: On the body section 2 of a cup-shape container 1 which is injection-molded using a polyolefin based resin or the like, a plurality of protruding ribs 5 are formed into a vertical line shape from the upper end to the lower end. Then, on a flange 4 at the opening, a lid material 6 comprising a laminated sheet having a sealant layer on the innermost surface is peelably sealed. Then, an external cylinder 10 made of paper, which is formed into a cylindrical form of an inverted frustum shape, is fitted on the container main body 1, and both bodies are integrated by bringing the internal surface of the external cylinder 10 into contact with the outer peripheries of the protruding ribs 5 of the container main body 1. By this constitution, this heat-insulating container which displays a high heat-insulating action, has a high rigidity and a high compression strength, on the surface of which, pictures or displays can be easily printed, and in addition, which can be easily disassembled, can be obtained.
