<P>PROBLEM TO BE SOLVED: To prevent deformation of a wall part made to abut on a cold storage target in a container even when a cold storage agent filled in the container is solidified and expanded. <P>SOLUTION: In the container 30 filled with the cold storage agent 40, a deformation wall part 35 formed to be recessed to the inner side of the container 30 is provided in a second wall part 34 constituting a face other than a first wall part 32 made to abut on the cold storage target D. The deformation wall part 35 is formed to be thinner than the first wall part 32 and is more easily deformed to the outer side of the container 30 compared to the first wall part 32. Therefore, when a cold storage body IC1 is cooled, in accordance with expansion of the solidified cold storage agent 40, the deformation wall part 35 is deformed to the outer side of the container 30, so as to prevent deformation of the first wall part 32. However, since the deformation wall part 35 is deformed within a range inside outer peripheral parts 35B and corner parts 35C of the deformation wall part 35, the outer shape dimension of the container 30 is not increased substantially. <P>COPYRIGHT: (C)2011,JPO&INPIT |
