PROBLEM TO BE SOLVED: To provide an cold box, in which an object to be cooled is housed together with a cold reserving material and the temperature of the object to be cooled is kept in a predetermined range, and which is made comparatively lightweight, is easy to carry, and has excellent durability, in which it is extremely easy to take out and put in the object to be cooled and the cold reserving material and in addition, the temperature of the object to be cooled can be kept constant over a long time.SOLUTION: The cold box includes: a portable outer case 1 having a flexible structure and an inner case 2 having thermal insulation properties. The inner case 2 is disposed to be positioned in the outer case 1 while leaving a gap on the outside surface side of an inner case body 20. A partition member of a structure, in which a cylindrical body is erected along the center line of the inner case body 20, is disposed in the inner case body 20. In a state where a lid 11 of the outer case 1 and a cover 21 of the inner case 2 are opened, the object to be cooled can be directly taken out from and put in the inside of the cylindrical body from above, and the cold reserving material can be directly taken out from and put in the outer peripheral part of the cylindrical body from above.COPYRIGHT: (C)2013,JPO&INPIT【課題】保冷材と共に被冷却物を収容して当該被冷却物の温度を所定範囲に保持する保冷容器であって、比較的軽量で携行し易く、耐久性に優れ、被冷却物や保冷材の出し入れが極めて容易であり、しかも、被冷却物の温度を長時間に渡って一定に保持し得る保冷容器を提供する。【解決手段】保冷容器は、柔軟な構造を有する可搬式の外箱1と、断熱性を有する内箱2とを備え、内箱2は、内箱本体20の外側面側に隙間を設けて外箱1の中に位置決めされた状態に配置される。内箱本体20内には、当該内箱本体の中心線に沿って筒状体を立設した構造の仕切部材が配置されており、外箱1の蓋11及び内箱2の蓋21を開けた状態において、筒状体の内部に被冷却物を上方から直接出し入れ可能で且つ筒状体の外周部に保冷材を上方から直接出し入れ可能に構成されている。【選択図】図1
