PROBLEM TO BE SOLVED: To provide a cold insulating container capable of reducing variance between the cold insulation performance of the bottom cold insulating container and that of another cold insulating container even when such cold insulating containers are stacked in a vertical direction.SOLUTION: A cold insulating container 10 includes a container body 20 and a lid body 30 to be attached thereto, and is used to be stacked on other cold insulating containers in a vertical direction. A plurality of bottom part through holes 26 are formed on a bottom part 24 of the container body 20. On an outside bottom surface 20b constituting the bottom part 24 of the container body 20, a plurality of support projections 27 supporting the cold insulating container 10 are formed. A packaged article whose weight is equivalent to 80% of the volume of a storage space in terms of water, is stored in the storage space of the cold insulating container. The support projections 27 are so formed that when such cold insulating containers are stacked in the vertical direction by the number of stages selected from any of three to six and are loaded on a loading surface, the bottom part through holes 26 cannot be closed by the loading surface, and when they are stacked by more than the selected number of stages and are loaded on the loading surface, the bottom part through holes 26 are closed by the loading surface since the support projections 27 of the bottom cold insulating container 10 are compressed and deformed.SELECTED DRAWING: Figure 8 |
