4, in the blanking step S1, the paper container 100 is formed in a multi-ply paper sheet 200 to which a corrugated paper sheet 220 is applied so that an air layer is formed inside to improve the heat insulation (keeping warm / cold) And then removing the container-formed paper 300 in a disk-shaped size. In the embodiment of the present invention, the paper container raw paper 200 is formed into a multi-layer structure so that an air layer can be formed therein. In the embodiment of the present invention, a corrugated paperboard 210 (also called a cup paper or a paper container) 220) + foodstuff 230 (which forms the outer surface of the paper container), and the like. A process of separating the container forming paper 300 into a disk-like shape in such a size that the paper container 100 can be formed through the wooden form in the multi-ply paper 200 to which the corrugated cardboard 220 is applied is performed in a blanking step S1 Process &quot;). In this blanking step S1, it is preferable to form the corrugation 121 (also referred to as "corrugation") on the container forming paper 300 so that the paper container forming in the container forming step S3 is easily performed. That is, when the container forming paper 300 is radially pressed to form the corrugations 121, The paper container of the container forming paper 300 can be easily formed while being deformed along the lines of the wrinkles 121.
