Abstract
It is an object of the present invention to provide a hollow bottle made of polyester, which has excellent heat resistance and is not likely to undergo deformation or change in capacity even if a liquid of high temperature is filled therein. The present invention relates to a hollow bottle formed by blow molding polyester, which has a thickness in the range of 200 to 400 μm, and satisfies that Δd=d−dis not less than −7 kg/mand more than 7 kg/m, with d[kg/m] being a density of a part ranging from an outer surface up to 50 μm inward, and d[kg/m] being a density of a part of the body portion ranging from an inner surface up to 50 μm inward. The polyester is preferably polyethylene terephthalate, and it is preferable that d=1370 to 1375 kg/m, while d=1373 to 1378 kg/m.
