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.COPYRIGHT: (C)2014,JPO&INPIT【課題】鮮度が落ちてしまうことが抑制できる保冷容器を提供する。【解決手段】容器本体3と、容器本体3の開口部2を開閉する上蓋とを備え、容器本体3は、底壁30と、底壁30から立設された左右側壁310,310と、底壁30から立設され左右側壁310,310と互いに連結された前後側壁320,320とを備え、一方の側壁310,310の長さ方向中間部の内面310Aに、容器本体3内の空間を複数の空間3A,3Bに仕切る仕切板5の両側端が嵌合する縦凹溝310Mが形成され、縦凹溝30Mに嵌合した仕切板5の下端が嵌合する横凹溝30Mが底壁30に形成され、仕切板5で仕切られた空間3A,3B同士間での液体のやり取りが行えるよう、液体を案内するための液体案内用の凹溝30Nが横凹溝30Mと交差するように底壁30に形成されている。【選択図】 図2
