1. An isothermal container comprising:
a heat insulating container including i) an outer cover material formed in a box shape having side faces and a bottom face with an open upper face, ii) an inner cover material disposed inside the outer cover material, iii) a core material disposed between the outer cover material and the inner cover material, and iv) an adsorbent disposed between the outer cover material and the inner cover material, the outer cover material and the inner cover material facing each other, the hear insulating container including a housing space inside the heat insulating container;
a heat insulating lid configured to close the heat insulating container;
a protection case that covers outside of the heat insulating container and outside of the heat insulating lid;
a box body housed in the housing space inside the heat insulating container;
a box lid configured to close the box body; and
a phase change material provided on a bottom portion and a wall portion of the box body and the box lid, wherein
the inner cover material has a first flange portion on an outer peripheral edge of the inner cover material such that the first flange portion extends outward away from the housing space and beyond the respective side faces of the outer cover material,
the outer cover material has a second flange portion on an outer peripheral edge of the inner cover material such that the second flange extends outward away from the housing space and beyond the respective side faces of the outer cover material,
the first flange portion of the inner cover material and the second flange portion of the outer cover material join each other such that the first flange portion of the inner cover material overlaps the second flange portion of the outer cover material in plan view, and
the heat insulating lid overlaps a joined part of the first flange portion and the second flange portion in plan view such that the heat insulating lid, the first flange portion, and the second flange portion are arranged in the mentioned order from a heat insulating lid side toward a heat insulating container side.
