摘要：
A multilayered container having an intermediate layer that contains a resin composition B obtained by blending a resin composition A that contains at least a resin (a) having a hydroxyl group with a carboxyl compound (b) of which the α-carbon is quaternary and of which the carboxyl group is forming no metal salt, wherein a ratio (COOH/OH) of the amount of the carboxyl groups of the carboxyl compound (b) to the amount of the hydroxyl groups of the resin (a) in the resin composition A is not more than 0.4. The multilayered container maintains excellent anti-eluting property and flavor-retaining property even when it is subjected to the retort sterilization.
