VACUUM HEAT INSULATION BOX BODY

摘要

PROBLEM TO BE SOLVED: To provide a vacuum heat insulation box body which uses a gas adsorption device capable of maintaining adsorption performance of a gas adsorbent till use.

SOLUTION: The gas adsorption device 1 which is disposed with a core material 16 within a space 17 formed between an outer box 14 and an inner box 15 comprises a container consisting of the gas adsorbent, a moisture adsorbent and a gas permeability retardant element. The container is configured so that the interior is partitioned into at least two or more accommodation spaces by a partition capable of adjusting permeability. The gas adsorbent and the moisture adsorbent are accommodated in different accommodation spaces of the containers. The vacuum heat insulation box body is configured so as to have a through-hole at predetermined temperature rise in the container which forms the accommodation space in which the moisture adsorbent is accommodated.
