Title:
VACUUM THERMAL INSULATION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2024/084774
Kind Code:
A1
Abstract:
The present disclosure provides a vacuum thermal insulation material which is capable of suppressing the formation of a heat bridge, while ensuring gas barrier properties, and which enables easy identification of the position of an adsorption device. This vacuum thermal insulation material comprises a core material 11, an adsorption device 20 which adsorbs air or moisture, and an outer cover material 30 which has gas barrier properties; and the core material 11 and the adsorption device 20 are covered and vacuum sealed by the outer cover material 30. The outer cover material 30 is formed of a laminate film, the entire surface of which is transparent; and the adsorption device 20 comprises an opening 24 that brings the outside and the inside of the adsorption device 20 into communication with each other, and an opening mechanism 25 for the opening 24.
