WE CLAIM:
[Claim 1]
A thermal insulation double container comprising:
a cup-shaped inner container comprising a cylindrical cup body member and a bottom member sealing a bottom of the cylindrical cup body member; and
an exterior sleeve covering the cup body member so as to form a thermal insulation space between the sleeve and an external surface of the cup body member of the cup-shaped inner container, wherein
the cup body member and the bottom member are each formed of a lamination in which at least a substrate layer made of paper, an adhesive layer, a barrier layer, and a seal layer are laminated, and
the adhesive layer comprises a resin composition comprising one or more selected from the group consisting of an epoxy group-containing compound, a silane group-containing compound, a carboxylic acid group-containing compound and an acid anhydride-containing compound. [Claim 2]
The thermal insulation double container according to claim 1, wherein a thickness of the adhesive layer is 15 Jim or more and 50 fjm or less. [Claim 3]
The thermal insulation double container according to claim 1 or 2, wherein the barrier layer comprises a resin

film and an inorganic oxide-deposited film or a metal-deposited film laminated on one side of the resin film. [Claim 4]
The thermal insulation double container according to any one of claims 1 to 3, wherein any one or both of the seal layer in the lamination forming the cup body member and the seal layer in the lamination forming the bottom member have a density of 0.900 or more and 0.925 or less and a melt index of 1.0 or more and 20.0 or less, and comprise an ethylene-a-olefin copolymer resin obtained by polymerization with a single-site-type catalyst. [Claim 5]
The thermal insulation double container according to claim 4, wherein a pasting layer is provided between the barrier layer and the seal layer. [Claim 6]
The thermal insulation double container according to claim 4 or 5, wherein a melting point of the adhesive layer is higher than a melting point of the seal layer.
