PROBLEM TO BE SOLVED: To provide a draw-molded multilayer container with excellent interlayer adhesion, appearance, uniformity of layer thickness and self-supporting ability. SOLUTION: The container includes, as an intermediate layer, an ethylene-vinyl alcohol copolymer (A) obtained by saponifying a copolymer including the following structural unit (1), preferably the copolymer obtained by copolymerizing 3, 4-diacyloxy-1-butene, a vinyl-ester-based monomer and ethylene, and at least polyolefin-based resin (B) layers on both external layers. X refers to an arbitrary linkage chain except ether linkage, R1-R4 independently refer to arbitrary substituents, and n refers to 0 or 1. COPYRIGHT: (C)2006,JPO&NCIPI
