Abstract: PURPOSE:To improve the barrier performance against gas such as oxygen, carbon dioxide, or the like, and water vapor by forming a multilayer vessel comprising at least two layers of thermoplastic polyester having a specified composition and polyolefin. CONSTITUTION:A perform is molded by injection molding, which comprises at least two layers of a thermoplastic layer containing an ethylene naphthalate unit of 80mol% as a repeated unit and a polyolefinic layer. It is then subjected to draw/blow molding in at least single axis direction at a temperature of 110-170 deg.C, to thereby form a multilayer vessel. The used polyolefin preferably contains a propylene unit of 70mol% as a repeated unit, and also may be a copolymer of olefin such as 1-octane of 30mol%. In order to enhance the transparency, and the barrier performance against gas such as oxygen, carbon dioxide or the like in the vessel, it is preferable to effect the draw-molding in at least a single axis direction.
