PROBLEM TO BE SOLVED: To hold cold reserving force and to prevent water leakage by preventing the opening of a cover body even when the latch of an opening and closing operation part is unlatched at the time of transportation. SOLUTION: This cold insulation box A is provided with a connection part 4 across a containing body 1 and a cover body 2 covering the top of the containing body 1 so as to connect the cover body 2 to be opened and closed. The box A is provided with the opening and closing operation part 5 latching and unlatching the containing body 1 and the cover body 2 on a releasing side opposed to this connection part 4. In this case, a handle 3 is fixed to both side parts orthogonal with the connection part 4 of the containing body 1 by mutually bridging both side parts to be capable of rolling, and a latching means B is provided across this handle 3 and the cover body 2 so as to latch and unlatch the handle 3 to the cover body 2 by moving the handle 3 rise and fall. |
