PROBLEM TO BE SOLVED: To provide a cylindrical container which has a double structure formed by inner and outer tubes and achieves higher cold/heat insulation performance.SOLUTION: A container has: a body part formed by a cylinder having a double structure composed of an inner tube and an outer tube; and a bottom part and a lid part for sealing. The container stores a content in a center part of the inner tube. The inner tube is formed by a lamination body including an aluminium foil. The outer tube is formed by a lamination body including a foam layer. A space between the inner tube and the outer tube is filled with a cold insulator.SELECTED DRAWING: Figure 1 |
