<p><P>PROBLEM TO BE SOLVED: To improve heat insulation properties by restricting a portion producing heat bridge only to the periphery of a cylindrical opening portion to shut off heat from escaping therefrom or entering therein, in a vacuum heat insulation container with its cylindrical opening part formed projecting outward. <P>SOLUTION: The vacuum heat insulation container is constituted of a container 11 having a cylindrical opening part 15 projecting outward and a vacuum heat insulation member 21 covering the outer face of the container 11 as well as surrounding the side faces 15a of the cylindrical opening part 15 with the cylindrical opening part 15. The vacuum heat insulation member 21 stores a heat insulation body 25 shaped in a double structure bag body 24 comprising an inner bag 22 and an outer bag 23, and makes the space between the inner bag 22 and the outer bag 23 vacuum. The heat insulation body 25 is constituted of a bottom block 25a, a cylindrical side block 25b and an upper block 25c. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
