PROBLEM TO BE SOLVED: To provide a new paper container having good stacking properties before use, and capable of forming a desired insulation space just before use.SOLUTION: A paper container includes: a paper container body comprising a top opening increasing the diameter toward an upper part, a paper body member having a rim part with the opening upper edge curled outward and a paper bottom plate member fixed to the bottom of the body member; and a paper cylindrical belly band fitted in the lower part of the rim part of the container body. In the paper container, a protrusion locking part is disposed on the lower edge outer circumferential surface of the body member, and a height of the cylindrical belly band is higher than the height from the lower side of the rim of the body member to the lower end of the body member. Accordingly, an insulation space can be formed between the outer wall surface of the body member and the inner wall surface of the cylindrical belly band, by locking the lower end of the cylindrical belly band to the upper end part of the protrusion locking part. |
