Abstract
The invention realizes easy manufacturing of a flat container molded by blow molding, in which the wall thickness of a container wall is made uniform, and which provides improved mechanical strength, heat resistance, etc. and has a good appearance. The flat container obtained by the blow molding of a polyester resin is characterized in that the container has a flatness ratio of not less than 1.3, and in that its body has a wall thickness ratio of a maximum wall thickness to a minimum wall thickness of not more than 1.6, a difference in elongation between a maximally stretched portion and a minimally stretched portion of not more than 150% in a tensile test at 95° C., a crystallinity of not less than 30%, and a difference in TMA non-load change between a maximally stretched portion and a minimally stretched portion of not more than 500 μm at 75° C. and 100° C.
