Abstract: A method of manufacturing an off-center container includes: stretching a preform made of resin having a bottomed shape with a stretching rod, heating the preform; and blow-molding the off-center container, in which a central axis of a neck portion is displaced from a central axis of a body portion, by introducing a pressurized fluid into the preform disposed in a mold. The container has a flat shape and a dimension in a first direction in a cross section is longer than in a second direction perpendicular to the first direction. In a circumferential cross section of the preform, a thickness of a first region corresponding to a surface extending in the first direction of the container is set to be thicker than a thickness of a second region corresponding to a surface extending in the second direction of the container.

Abstract: A blow molding machine includes a support member and a moving mechanism that moves the support member to a projecting position a storing position. The blow molding machine includes a first fixed fulcrum shaft, and the support member includes a base end portion rotatably supported by the first fixed fulcrum shaft and a free end portion provided with a first movable fulcrum shaft. The moving mechanism includes a plurality of links connected rotatably to each other, one of the plurality of links being rotatably supported by the movable fulcrum shaft of the support member, and, when the support member is set at the projecting position, the plurality of links are maintained linearly by a first angle fixing tool, thereby enabling the plurality of links to serve as a leg portion that supports the free end portion of the support member.
