Abstract: A wide-neck synthetic resin container has a neck, a body and a bottom. A top side of the neck is sealed by a cap. The neck includes a neck tubular section, an engagement section protruding outward therefrom and engaging the cap, and a flange protruding outward at the top side. The flange protrudes less than the engagement section. The neck's top side includes a first top side formed by the neck tubular section, and a second top side formed by the flange that is the same height level with the first top side and increases an area of the top side. The neck tubular section has a uniform thickness at an area immediately below the flange and an area where the engagement section is formed. A thickness of the flange is smaller than that of the neck tubular section, and the neck has been crystallized.

Abstract: A neck crystallization method includes inserting a core into the neck, heating the neck using a heater group disposed along a transfer direction while rotating the preform on its axis, and transferring the preform along the transfer direction in a state in which the core is inserted into the neck, and cooling the neck of the preform in a state in which the core is inserted into the neck. The heating of the neck includes a first step that drives first heaters positioned on the upstream side in the transfer direction at a first power, and a second step that drives second heaters positioned on the downstream side of the first heaters at a second power that is lower than the first power until the temperature of the neck reaches a crystallization temperature zone.
