According to this, when heat is transferred through the core material 35 in the thickness direction of the vacuum insulation container 3, the heat transfer path becomes longer than the thickness because the heat is transferred through the inorganic fibers, and the heat transfer is suppressed. Therefore, the heat retention of the constant temperature container 1 can be improved.
  • the peripheral edge of the second core material 131 is impregnated with an organic substance made of open cell foam. Therefore, a gap is less likely to occur at the boundary between the second core material 131 made of an inorganic substance and the first core material 31 made of an organic substance. Therefore, the occurrence of a portion where the thickness of the core material 35 is extremely thin is reduced, and the heat retention of the constant temperature container 1 can be improved.
  • the second core material 131 is located at least above the wall portion 132 of the vacuum insulation container 3, that is, near the opening of the wall portion 132. Therefore, the rigidity of the core material 35 near the opening can be improved by the second core material 131 made of an inorganic substance, and the molding accuracy of the opening of the vacuum insulation container 3 can be improved. As a result, a gap is less likely to occur between the opening and the vacuum heat insulating lid 4 that closes the opening, and the heat retention of the vacuum heat insulating container 3 can be improved.
  • the second core material 131 is located closer to the inside of the wall portion 132 of the vacuum insulation container 3.
  • the thermal conductivity of the communication urethane becomes smaller at a temperature lower than room temperature.
  • the vacuum insulation container 3 which is transported near room temperature or at a temperature higher than room temperature
  • heat is retained by arranging a second core material 131 made of an inorganic substance having a small temperature dependence of thermal conductivity near the inside of the wall portion 132. Performance can be improved.
  • a second core material 131 made of an inorganic substance is arranged near the outside of the wall portion 132. May be good. Thereby, the heat retention performance can be improved.
  • the density of the second core material 131 of the inorganic substance is, for example, 150 kg / m 3 or more at atmospheric pressure.
  • the outer outer cover material 34 and the inner outer cover material 33 are made of resin. Since the outer cover material is made of resin, the amount of heat that enters and exits through the outer cover material is reduced as compared with the case where the metal layer is provided, and the heat retention of the vacuum heat insulating container 3 can be improved.
  • the constant temperature container according to the present invention can be suitably used as a constant temperature container for storing articles that are kept cold and warm in a constant temperature range and require quality control during transportation.
  • Constant temperature container Vacuum insulation container (insulation container) 31 1st core material 33 Inner outer cover material 34 Outer outer cover material 35 Core material 131 2nd core material 132 Wall part
