A storing volume is formed within a box which also houses a temperature detector for detecting the temperature of the gas within the storing volume, a cooling mechanism for cooling the interior of the storing volume, a nitrogen-rich gas supplying device, for supplying nitrogen-rich gas into the storing volume, and a controller which functions in such a manner that it activates the cooling mechanism in response to signals from the temperature detector in order to control the temperature of the interior of the storing volume, and also activates the nitrogen-rich gas supplying device in response to the variation of the gas contents of the storing volume in order to control the gas contents of the storing volume. Due to the function of the nitrogen-rich gas supplying device, the nitrogen concentration can be maintained within the storing volume at a proper level all the time, and therefore the respiration of the fresh foods stored in the storing volume is inhibited, thereby contributing to keeping the fresh foods in a fresh state, and preventing rotting. Further, a pressure regulator prevents the leaking of the cooled nitrogen-rich gas from the interior of the storing volume to the outside.
