Abstract: A method for manufacturing a resin container includes a first step of accommodating an injection-molded bottomed resin preform in a temperature-adjusted mold and adjusting a temperature of the preform by the mold, a second step of moving the mold by a predetermined amount in an axial direction with respect to the preform by a lifting and lowering device and then stopping the mold, and causing an air ejection part arranged on an upper surface side of the mold to face a portion of the preform to be cooled, a third step of ejecting air from the air ejection part to locally cool the portion to be cooled of the preform positioned in the axial direction, and a blow molding step of blow molding the preform whose temperature has been adjusted through the first to third steps and manufacturing a resin container.

Abstract: The present application includes an injection molding step and a stretch blow molding step. The stretch blow molding step is configured to include: a first step in which preliminary blow air is introduced into a preform to stretch the preform in a state in which a stretching rod does not contact the bottom of the preform; a second step which is executed after the first step, and in which the preliminary blow air is introduced into the preform and the stretching rod is moved at a set speed and pressed against the bottom of the preform to stretch the preform; and a third step which is executed after the second step, and in which final blow air is introduced into the preform to stretch the preform.

Abstract: This resin-made container is provided with: a neck portion having a content inlet-outlet portion; a lateral surface portion connected to the neck portion; and a bottom portion that is disposed on the side opposite to the neck portion and that is connected to the lateral surface portion. The resin-made container is produced by a stretch blow molding process. The bottom portion has formed therein a bulge section that protrudes downward in the vertical direction. The bulge section is disposed in an eccentric region, of the bottom portion, positioned outside a region demarcated by perpendicularly projecting an opening plane of the inlet-outlet portion of the neck portion.
