Title:
気体吸着デバイスおよび真空断熱材
Document Type and Number:
Japanese Patent JP7209352
Kind Code:
B2
Abstract:
To provide a gas adsorption device capable of preventing an opening hole from being in a packaging container in a stage of manufacturing a vacuum heat insulating material, and capable of realizing stabilization of performance of the vacuum heat insulating material, and provide a vacuum heat insulating material.SOLUTION: A gas adsorption device comprises a packaging container 11, a gas adsorbent 12, and an opening member 14. The opening member 14 comprises a coil spring-like elastic member 20 composed of a plurality of winding parts 23, a pin support part 21, an opening pin 22, and a grip part 24 for sandwiching the packaging container 11. The opening pin 22 is formed so that the tip part of the opening pin 22 does not come into contact with the packaging container 11 in a state where the elastic member 20 is compressed and deformed and the respective winding parts 23 come in contact with each other.SELECTED DRAWING: Figure 1
