Abstract

PURPOSE:To obtain the titled hollow body, a bottom section thereof is smooth, in which there is no whitening section and which is uniformly transparent, by a method wherein a parison is projected and molded, cut when a temperature of a gate section reaches a specified temperature and blow-molded. CONSTITUTION:When manufacturing a parison, which is formed by projecting and molding polyethylene terephthalate and in a bottom section thereof there is a trace of a gate section, the gate section is cut from a parison body when a temperature of a section to be cut of the gate section reaches 60-80 deg.C after injection molding. The parison is heated at a temperature at which an orientation, blow-molding is possible, and orientation, blow-molded.
