Abstract
Provided is a resin container manufacturing method including: an injection molding process of injection molding a plurality of preforms along a predetermined arrangement direction; a temperature adjustment process of adjusting a temperature of the preform; and a blow molding process of molding a resin container from the preform. After the injection molding process, the preform and the container are conveyed along a conveying direction intersecting the arrangement direction over the temperature adjustment process and the blow molding process. The temperature adjustment process includes a first temperature adjustment process of adjusting the temperature of the preform, a second temperature adjustment process of adjusting the temperature of the preform under a condition different from that of the first temperature adjustment process, and a fine adjustment process of finely adjusting the temperature of the preform.
