Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a polyethylene injection oriented blow molded container having uniform thickness, uniform and excellent luster of the whole container and cleanness. SOLUTION: This clean container is obtained by subjecting an ethylene homopolymer or a copolymer of ethylene and an α-olefin to injection orientes blow molding. The ethylene homopolymer or the copolymer of an α-olefin and ethylene has (A) 0.5-10 g/10 minutes melt index (MI2.16 ) at 190 deg.C under 2.16 kg load, (B) 3-6 molecular weight distribution measured by gel permeation chromatography, (C) >=0.935 g/cm density, (D) 1,000 Pa.s to 20,000 Pa.s viscosity (η0.1 ) at 200 deg.C at 0.1 rad/s shear rate and (E) 300 Pa.s to 2,000 Pa.s viscosity (η100 ) at 200 deg.C at 100 rad/s shear rate.
