PROBLEM TO BE SOLVED: To provide a squeezing vessel which is non-adsorptive to active principles and perfume of contents such as medicines and food. SOLUTION: This squeezing vessel is formed by blow-molding multi-layered parison with a bottom opening end heat-sealed, and the multi-layered parison is a laminate comprising an olefin resin outer layer, an inner layer of substantially amorphous copolymer polyester which consists of diol other than cyclohexane methanol and dicarboxyl acid other than isophthalic acid while diol consisting of ethylene glycol and diol other than ethylene glycol and mole percentage of ethylene glycol to diol other than ethylene glycol is 50:50 to 95:5, and an adhesive resin intermediate layer, and the bottom-sealed part is substantially amorphous with inner layers bonded to each other.
