Abstract:
1. A storage container storing preserved goods and having an electrical cooling function, the storage container including a container body and a lid capable of optionally opening and closing a space in the container body, wherein the space enclosed by the container body and the lid forms a storage room for storing the preserved goods, each of the container body and the lid has a heat insulating portion disposed to surround the storage room and a heat accumulating portion at least partly disposed between the storage room and the heat insulating portion, the heat accumulating portion is made of at least one type of material that causes phase transition between a liquid phase and a solid phase at a temperature between a controllable temperature inside the storage room during a stationary operation and a living environmental temperature around the storage room, and a value obtained by dividing temperature conductivity of the material by an amount of the material used per unit area of a wall surface of the storage room is smaller in the heat accumulating portion arranged near a first area where a temperature is more apt to come closer to the living environmental temperature under a temperature distribution that is formed inside the storage room with changes over time after the electrical cooling function is stopped in a stationary operation state, than in the heat accumulating portion arranged near a second area where a temperature is less apt to come closer to the living environmental temperature under the temperature distribution.
