Storage container utilizing two different heat insulating materials in combination with a temperature control unit and a heat storage material placed within the container

摘要

Performance of heat insulation between the outside of a storage container and the inside of a storage chamber is effectively improved. The storage container includes a container body having an opening, a door member closing the opening in an openable and closable manner, and a temperature-controlled unit having a function of making a temperature inside a storage chamber 2 enclosed by the container body and the door member be different from a temperature outside the storage chamber. The container body includes a first heat-insulating material 14, a second heat-insulating material 15 which is provided partially on the opposite side to the storage chamber 2 with respect to the first heat-insulating material 14 and has thermal conductivity lower than that of the first heat-insulating material 14, and a heat-storage material 16 which is provided at least partially in a region where the second heat-insulating material 15 is not provided as viewed from a thickness direction of the first heat-insulating material 14 on the same side as the storage chamber 2 with respect to the first heat-insulating material 14 and is formed of one or more kinds of raw material where phase transition is caused between a liquid phase and a solid phase at a temperature between the temperature outside the storage chamber 2 and the temperature inside the storage chamber 2 obtained by the function of the temperature-controlled unit.

1. A storage container comprising:
a container body having an opening; a door member closing the opening in an openable and closable manner; and a temperature-controlled unit having a function of making a temperature inside a storage chamber enclosed by the container body and the door member different from a temperature outside the storage chamber, wherein the container body includes a first heat-insulating material, a second heat-insulating material which is provided partially on the opposite side to the storage chamber with respect to the first heat-insulating material and has thermal conductivity lower than thermal conductivity of the first heat-insulating material, and a stationary heat-storage material which is continuously and fixedly provided at least partially in a region where the second heat-insulating material is not provided as viewed from a thickness direction of the first heat-insulating material on the same side as the storage chamber with respect to the first heat-insulating material and is formed of one or more kinds of raw material where phase transition is caused between a liquid phase and a solid phase at a temperature between the temperature outside the storage chamber and the temperature inside the storage chamber obtained by the function of the temperature-controlled unit.
