PROBLEM TO BE SOLVED: To improve the heat insulation performance and the durability without forming a plated layer by bonding an outer container comprising an inner wall body and an outer wall body with an inner container which is multiple-layered with different synthetic resin materials across a space layer, and filling the prescribed low thermal conductive gas in the space layer to form a heat insulation layer. SOLUTION: A container 1 comprises a multi-colored multiple-layered inner container 2, and an outer container comprising an inner wall body 3 which is injection-molded so as to be laminated on each other and an outer wall body 4, the inner container 2 is stored in the inner wall body 3 of the outer container keeping a space layer therebetween, and an end part 2c of the inner container is integrated with an end part 3a of the inner wall body of the outer container to form a double-walled structure. At least one kind of xenon gas, krypton gas and argon gas is introduced in the space layer 5 through an open hole part 3b, and sealed by a sealing plate 9 to form a heat insulation layer 6. The inner container 2 provided with excellent gas barrier property can be obtained without plating the outer surface of the inner container 2 by forming the inner container 2 of the excellent gas barrier property resin and the humidity-proof resin. |
