A molded container having a wall composed of a thermoplastic resin oriented in at least one direction on the wall face, wherein the container wall consists essentially of a single layer of a blend composed mainly of a plurality of melt-extrudable thermoplastic resins, each of said thermoplastic resins having a solubility parameter (Sp) of at least 9.5, each of said thermoplastic resins having an oxygen permeability lower than 5×10-11 ccㆍcm/cm2ㆍsecㆍcmHg, said thermoplastic resins being chosen so that the difference (D4.5, one (A) of said thermoplastic resins having an oxygen permeability lower than 5×10-11 ccㆍcm/cm2ㆍsecㆍcmHg and being an ethylene-vinyl alcohol copolymer having an ethylene content of 25 to 50 mole %, another (B) of said thermoplastic resins having an oxygen permeability lower than 5×10-11 ccㆍcm/cm2ㆍsecㆍcmHg and including at least one member selected from homopolyamides and copolyamides having 3 to 30 amide groups per 100 carbon atoms in the molecule, said blend being one formed by mixing said resin (A) and said resin (B) at a weight ratio (A):(B) of from 90:10 to 10:90 with the elongation of said blend being higher than the arithmetric mean (ed5% in the orientation direction of said container wall. A container formed by biaxial draw-blow molding of a parison composed of a thermoplastic resin, said parison having a multi-layer structure including at least one layer of a blend composed mainly of a plurality of melt-extrudable thermoplastic resins, each melt-extrudable thermoplastic resin having a solubility parameter (Sp) of at least 9.5, and at least one layer composed of a creep-resistant thermoplastic resin in which the sum of the instantaneous modulus (Eg) and retardation modulus (E1) at a temperature of 23°C. and a stress of 7×107 dyne/cm2 is at least 1×1010 dyne/cm2 and which has a steady state flow viscosity (h∽) of at least 1×1017 poise and a retardation time (tR) shorter than 6×106 sec, each of said thermoplastic resins in said blend having an oxygen permeability lower than 5×10-11 ccㆍcm/cm2ㆍsecㆍcmHg, one (A) of said thermoplastic resins in said blend being an ethylene-vinyl alcohol copolymer having an ethylene content of 25 to 50 mole %, another (B) of said thermoplastic resins in said blend including at least one member selected from the group consisting of homopolyamides and copolyamides having 3 to 30 amide groups per 100 carbon atoms in the molecule, said blend being one formed by mixing said resin (A) and said resin (B) at a weight ratio (A):(B) of from 90:10 to 10:90, with the difference (D4.5 and the elongation of said resin blend being higher than the arithmetric mean (ed5% in the orientation direction of said container wall.
