A multi-layered bottle having a barrel section including an outermost layer, an innermost layer, and at least one barrier layer between the outermost layer and the innermost layer. The multi-layered bottle satisfies the following conditions at the same time: (1) OTR <= 0.2 cc mm/(m^2.day.atm)(OTR is an average oxygen permeability coefficient of the barrel section barrier layer), (2) 20 <= average degree of orientation of the barrel section barrier layer <= 45, and (3) 0 <= b/a x 10 <= 200 (a: average thickness (mum) of the barrel section barrier layer, b: average thickness (mum) of a bottom section barrier layer). The multi-layered bottle is, although it has projected/recessed sections and bent sections, less likely to have interlayer separation and, as a consequence, has a high degree of design freedom. |
