    摘要： There is provided a multilayer bottle including outermost and innermost layers each made mainly of a polyester (A) and at least one barrier layer interposed between the outermost and innermost layers. The polyester (A) is a thermoplastic resin obtained by polymerizing a dicarboxylic acid component containing 80 mol % or more of terephthalic acid with a diol component containing 80 mol % or more of ethylene glycol. The barrier layer is composed of a polyamide (B) and a polyamide (C). The polyamide (B) is obtained by polycondensing a diamine component containing 70 mol % or more of m-xylylenediamine with a dicarboxylic acid component containing 70 mol % or more of an α,ω-linear aliphatic dicarboxylic acid having 4 to 20 carbon atoms. The polyamide (C) has a higher saturation water content than that of the polyamide (B) as measured at 23° C. and 50% RH under 1 atm, and a content of the polyamide (C) in the barrier layer is 20% by weight or less on the basis of a weight of the barrier layer. The multilayer bottle hardly suffers from delamination upon dropping or upon exposure to impact and, therefore, is not required to have a shape with less irregularities or less bends for preventing the delamination, and further has a large freedom of design choice.
