Thermally insulated container
A thermally insulated container includes a container main body having a storage section and an opening, a lid body that covers the opening of the container main body, and an inner box stored in the storage section. The lid body has a convex portion arranged along a periphery of the opening of the container main body and protruding toward an inside of the storage section when the lid body covers the opening. The convex portion faces the inner box, with a gap between the convex portion and the inner box when the lid body covers the opening.
1. A thermally insulated container comprising:
a container main body having a storage section and an opening;
a lid body that covers the opening of the container main body; and
an inner box stored in the storage section,
wherein the lid body has a convex portion, the convex portion being arranged along a periphery of the opening of the container main body and protruding toward an inside of the storage section when the lid body covers the opening,

the heat storage material is disposed closer to an outer surface of the inner box than the heat-transfer body is, and
the inner box is not in contact with a side of the storage section of the container main body.
2. The thermally insulated container according to claim 1 , wherein the convex portion comes into contact with an inner peripheral surface of the storage section when the lid body covers the opening.
3. The thermally insulated container according to claim 1 , wherein a distal end of the convex portion is positioned closer to a bottom portion of the storage section than an end portion of the inner box is, when the lid body covers the opening and the convex portion is located in the storage section.
4. The thermally insulated container according to claim 1 , further comprising
at least two wall bodies adjacent to each other, the at least two wall bodies each being the wall body, and
the at least two wall bodies are coupled to each other, at each one side adjacent to each other, with at least one of a detachable fixing member and the packaging members of the at least two wall bodies.
5. The thermally insulated container according to claim 1 , wherein a portion of the packaging member that covers the heat storage material is a transparent resin.
6. The thermally insulated container according to claim 1 , further comprising a physical quantity sensor disposed inside the inner box.
7. The thermally insulated container according to claim 1 , further comprising
an inner box fixing member configured to fix the inner box, the inner box fixing member being disposed at a bottom portion of the storage section of the container main body.
8. The thermally insulated container according to claim 7 , wherein the inner box fixing member is a separate member from the container main body and is in contact with the side of the storage section of the container main body.
9. The thermally insulated container according to claim 1 , wherein the heat-transfer body has a plate shape.
10. The thermally insulated container according to claim 1 , wherein in a planar view of the wall body, the heat-transfer body is larger than the heat storage material.
11. The thermally insulated container according to claim 1 , wherein at least one of the container main body and the lid body comprises a vacuum heat insulating housing.
12. A thermally insulated container comprising:
a container main body having a storage section and an opening;
a lid body that covers the opening of the container main body;
an inner box stored in the storage section; and
an inner box fixing member configured to fix the inner box, the inner box fixing member being disposed at a bottom portion of the storage section of the container main body,
wherein the lid body has a convex portion, the convex portion being arranged along a periphery of the opening of the container main body and protruding toward an inside of the storage section when the lid body covers the opening,
the convex portion faces the inner box, with a gap between the convex portion and the inner box when the lid body covers the opening,
the inner box is not in contact with a side of the storage section of the container main body,
the inner box fixing member is disposed between the inner box and a bottom portion of the storage section, and has a first surface in contact with the inner box and a second surface facing the bottom portion of the storage section, and
the inner box fixing member has a through hole penetrating from the first surface to the second surface.
13. The thermally insulated container according to claim 12 , wherein
the inner box fixing member is a separate member from the container main body, and
the second surface of the inner box fixing member is in contact with the bottom portion of the storage section of the container main body.
14. The thermally insulated container according to claim 12 , wherein the through hole is hollow.
15. The thermally insulated container according to claim 12 , wherein the through hole is one of a plurality of through holes.
