An object of the present invention is to improve shock resistance of nursing bottles formed of a PES resin so as to provide them with such a sufficient falling impact strength that they can be used pleasantly and safely. The injection-blow-molded PES nursing bottle of the present invention has a gate flash (6) at a central portion of a bottom (5), the flash being generated when the resin is previously injected to prepare a parison. The central bottom portion (5) is raised to be of a convex shape to bulge up towards a mouth of the bottle. A height 'h' of such a raised bottom portion is from 9 % to 20 % of an inner diameter 'R' that is possessed by a floor-engaging rim of the bottom, the rim being generally circular in a bottom plan view.
