Abstract: A method of manufacturing a resin container having a flat cross-sectional shape includes a temperature adjusting step of preliminarily blowing a resin preform in a first mold to mold an intermediate molded body having a diameter larger than a diameter of a container short diameter side and adjusting a temperature of the intermediate molded body in the first mold, and a blow molding step of bringing the temperature-adjusted intermediate molded body into contact with a second mold to compress the intermediate molded body in a container short diameter direction, and then stretching and blow molding the intermediate molded body in the second mold to manufacture the resin container.

Abstract: A temperature adjustment mold for adjusting a temperature of a preform that is injection-molded, has a bottomed shape, and is made of resin includes one or more adjusting portions that face a part of an outer peripheral surface of a body portion of the preform and locally heat a predetermined portion in a circumferential direction of the preform. The adjusting portion is disposed such that a gap is formed in the circumferential direction, and an attachment position is adjustable in the circumferential direction.

Abstract: Provided is a resin container for a water server, the container including an upper surface portion where a liquid inlet and outlet portion is formed, a side surface portion connected to the upper surface portion, and a bottom surface portion disposed on a side opposite to the upper surface portion and connected to the side surface portion. A round corner surface portion is formed to the side surface portion such that the container has a polygonal shape with round corners when the container is viewed from an upper surface portion side. A wall thickness of a shoulder portion of the upper surface portion which is defined between the round corner surface portion of the side surface portion and the inlet and outlet portion is larger than a wall thickness of a portion of the upper surface portion which is adjacent to the shoulder portion.
