To provide a molded bottle with a bottom, particularly a molded bottle having more enhanced impact resistance at a bottom part, and a molding die for molding the same.

The injection blow molded approximately cylindrical bottle with the bottom is composed of a polyphenylsulfon resin. The molded bottle has a bottom outer face wall formed of a concave raised to a gradual sphericity toward the center of the bottom part from the periphery side. A concentric central diving section is formed toward the upper part from the central part surface of the spherical concave. Further, an annular outside diving section is formed at the outside of the concentric central diving section through the intermediary of a concentric convex inside outer ring section. In addition, the bottom part inside wall of the molded bottle has an even spherical surface without irregularity. Also, the molding die for manufacturing the above molded bottle is provided.
