Abstract
A bottle-shaped container of saturated polyester having frosted or ground surface is manufactured by the steps of heating the outer layer portion of the injection-molded preformed piece to thereby crystallize the outer layer portion to opacify in white, and blow-molding the preformed piece in a blowing mold having at least part of its inner surface formed with rough surface sandblasted in advance to thereby form the rough surface on the bottle-shaped container on the crystallized outer layer portion surface. Thus, the bottle-shaped container incorporates pearl-like ground surface desired in a shape on the surface instead of the glossy surface peculiar to synthetic resin.
