PROBLEM TO BE SOLVED: To provide a cold box capable of performing easy stacking work.SOLUTION: Guide means are provided for guiding the upper cold box along a longitudinal direction when the upper cold box 1 is slid in the longitudinal direction with respect to the lower cold box 1 in order to stack the upper cold box 1 on the lower cold box 1. A plurality of the guide means are provided in a width direction, and include: longitudinal projecting portions 18A which project on one of the bottom surface of a vessel body 10 and the upper surface of an upper cover and extend along the longitudinal direction and widthwise projecting portions 24, 24, 25, 26 which project on the other of the bottom surface of the vessel body 10 and the upper surface of the upper cover and which are positioned at both sides in the width direction perpendicular to the longitudinal direction with respect to the longitudinal projecting portions 18A in guiding.COPYRIGHT: (C)2013,JPO&INPIT【課題】積み上げ作業を容易に行うことができる保冷容器を提供する。【解決手段】下側の保冷容器1に上側の保冷容器1を積み重ねるべく下側の保冷容器1に対して上側の保冷容器1を前後方向に摺動させる際に、前後方向に沿って上側の保冷容器を案内する案内手段を備え、案内手段は、容器本体10の底面又は前記上蓋の上面の一方に突設されると共に前後方向に沿って延設される前後方向凸部18Aと、容器本体10の底面又は前記上蓋の上面の他方に突設されると共に、案内の際に前後方向凸部18Aに対して前後方向に直交する幅方向の両側に位置するように設けられる幅方向凸部24,24,25,26とを備え、幅方向に複数設けられている。【選択図】 図5
