PROBLEM TO BE SOLVED: To provide a cold insulation container which is capable of suppressing deterioration of freshness.SOLUTION: A cold insulation container comprises a container body 3 and a top lid for opening and closing an opening 2 of the container body 3, with the container body 3 comprising a bottom wall 30, left and right side walls 310, 310 erected from the bottom wall 30 and front and back side walls 320, 320 which are erected from the bottom wall 30 and are mutually connected with the left and right side walls 310, 310. On inner surfaces 310A of the side walls 310, 310 in one direction, vertical recessed grooves 310M are formed in middle sections in a longitudinal direction, for fitting side ends of a partition plate 5 which partitions the space inside the container body 3 into a plurality of spaces 3A, 3B, and on the bottom wall 30, horizontal recessed grooves 30M are formed for fitting a lower end of the partition plate 5 fitted to the vertical recessed grooves 30M. On the bottom wall 30, recessed grooves 30N for guiding liquid are formed for guiding liquid in such a manner that they intersect with the horizontal recessed grooves 30M so as to allow exchange of liquid between the spaces 3A and 3B partitioned by the partition plate 5. |
