Title:
VACUUM INSULATION MATERIAL AND INSULATED BOX USING VACUUM INSULATION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/255884
Kind Code:
A1
Abstract:
The present invention addresses the problem of making it easy for a vacuum insulation material in which a flat core material is sealed in a depressurized state by a sheath material to be mounted on a curved surface. A vacuum insulation material that comprises a flat core material (3) and a sheath material (2) that covers the core material (3). First grooves (21) are formed in a width direction W center part (11) of the core material (3), and second grooves (22) are formed in two end parts (12, 13) of the core material (3) that are on either side of the center part (11) in the width direction W. When sealed in a depressurized state, the core material (3) deforms such that the curvature of the two end parts (12, 13) is greater than the curvature of the center part (11). As a result, the end parts (12, 13) can be easily mounted along a curved surface, and separation of the vacuum insulation material (1) from the curved surface can be reduced.
