Abstract

PURPOSE:To obtain a bottle whose body is molded into a circular shape, by blow molding a resin parison inserted in molds adjusted in a specific temperature range. CONSTITUTION:The parison P of a resin (e.g., polyethylene terephthalate) heated to a moderate temperature is inserted in the mold 1 whose wall face is maintained at 60-100 deg.C (preferably at 70-80 deg.C), and brough into contact with the wall face by introducing a fluid in the parison to form a bottle. In order to prevent the part under the bottle neck becoming thick, the temperature of the part under the bottle neck is preferably maintained 1-5 deg.C higher than that of the other part of the bottle and the parison is inserted in the face of the mold 1. The parison is then drawn not less than four times in the long direction by the drawing rod 4 inserted in it, and shaped by compressed fluid introduced.
