MULTI-LAYERED BOTTLE

摘要

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/(m².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 × 100 = 200 (a: average thickness (µm) of the barrel section barrier layer, b: average thickness (µm) 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.
