<p>PURPOSE:To improve the heat insulating effect by forming a multilayered heat insulating part from the heat insulating sheets laminatated in mutilayer form and allowing adsorbent to be interposed in dispersed state between the heat insulating sheets. CONSTITUTION:A multilayered heat insulating part 9 which is formed by laminating the heat insulating sheets 8 is formed on the surface of an inner tank 1, and a vacuum part 7 is formed between the surface of the multilayered heat insulating part 9 and an outer tank 2, and adsorbent 10 is interposed in the dispersed state between the heat insulating sheets 8. Therefore, the gas in the gap between the mutilayered heat insulating part is adsorbed, and the vacuum degree in the gap is improved, and the superior heat insulating effect can be obtained.</p> |
