Abstract
There is provided a multilayer bottle comprising a barrel portion including an outermost layer, an innermost layer and at least one barrier layer interposed between the outermost layer and the innermost layer, which satisfies the requirements represented by the following formulae (1) to (3) at the same time:OTR≦0.2 cc·mm/(m·day·atm)  (1)where OTR represents an average oxygen transmission rate of the barrier layer of the barrel portion;20≦(Average degree of orientation of barrier layer of barrel portion)≦45; and  (2)0≦×100≦200  (3)where 'a' represents an average thickness (μm) of the barrier layer of the barrel portion; and 'b' represents an average thickness (μm) of the barrier layer of a bottom portion of the bottle. The multilayer bottle is free from delamination owing to impact upon dropping even when the bottle is formed with irregularities and bends and therefore exhibits a large freedom of design choice.
