PROBLEM TO BE SOLVED: To facilitate setting of different coolant injecting conditions by identifying the information of a hold keeping box affixed with inherent information concerning to the flow-in quantity of a coolant through a sensor, determining the flow-in quantity of the coolant based on the inherent information thus read out and controlling a coolant injection means. SOLUTION: A truck 40 for mounting a rectangular prism collapsible thermal insulating cold keeping box 10 is fixed with four casters 43 to the underside of a box mounting board 41. A fence 42 is stood on the upper side of the mounting board 41 and a cooler 44 is mounted on the side face side thereof. A sensor 45 projecting from the cooler 44 can read out a bar code indicative of the coolant injection time for the cold keeping box 10. A central processing unit reads out the coolant injection time from the information at the bar code read out by means of the sensor 45 and controls a coolant injector to inject the coolant for a specified time into the built-up cold keeping box 10 from a coolant injection nozzle 46. |
