PROBLEM TO BE SOLVED: To improve safety of a double container.SOLUTION: A double container 1 includes: an inner container 14 that is equipped with a curl part 1 at an upper edge peripheral end and is composed of a cylindrical barrel part and a bottom part provided at a lowe end of the barrel part in the way that it closes a lower surface; an outer cylinder 15 which is put over the barrel part to form a heat-insulating space between itself and an outside of the barrel part of the inner container 14 and is fixed; and a lid material 10 which is bonded to the curl part 11 and blocks an upper surface of the barrel part. A cut line is formed on the outer cylinder 15, and a clip piece 21 is cut out of the outer cylinder 15 along the cut line. The clip piece 21 is used for holding an edge part of the lid material 10 that is partially pealed off from the curl part to the curl part 11. By the clip piece 21 being cut out of the outer cylinder 15, a protection piece 16 is provided inside a cut-out hole 15C formed on the outer cylinder 15, and the cut-out hole 15C is blocked from inside by the protection piece 16. |
