<p>Disclosed is a multilayer bottle having an outermost layer and innermost layer composed of a thermoplastic polyester resin, and at least one barrier layer arranged between the outermost layer and the innermost layer. The barrier layer is composed of at least two components, namely a polyamide obtained by polycondensing a diamine component mainly containing methaxylylenediamine and a dicarboxylic acid component mainly containing an alpha,omega-linear aliphatic dicarboxylic acid, and a thermoplastic resin having a lower molecular weight than the polyamide. Since separation due to dropping or impact hardly occurs in this multilayer bottle, it is not necessary for this multilayer bottled to have a shape with less projected, recessed and bent portions for preventing separations. Consequently, this multilayer bottle has a high degree of freedom in design.</p> |
