  • Patent number: 9091474
    Abstract: A storage container can maintain a temperature inside a storage room not to cause a temperature distribution for a certain time even if the operation is stopped. In a storage container 1 storing preserved goods and having an electrical cooling function, the storage container 1 includes a container body 10 and a door 20. A space enclosed by the container body 10 and the door 20 forms a storage room 100. The container body 10 and the door 20 have respectively heat insulating portions 12, 22 and heat accumulating portions 14, 24. The heat accumulating portions 14, 24 are each made of at least one type of material that causes liquid-solid phase transition at a temperature between a controllable temperature inside the storage room 100 and a living environmental temperature.
