Abstract

PURPOSE:To prevent a blushing phenomenon from occurring at the point of the projection of a parison to improve the value of a product by a method wherein a cavity is formed between a molded parison bottom under direct heating conduction and a gate to produce the projection on the bottom of the parison. CONSTITUTION:The bottomed parison 2 having a projection 5 on the bottom surface is molded by a parison injection molding machine A, cooled suddenly in the cavity 1 and the barrel part of the parison is molded in an unfrosted state excepting the projection 5 formed at a concave part 6 of the cavity 1 connected with the manifold 4. Then, this parison 2 is heated in a parison heater B and at the same time the cloudy blushed projection 5 made on the bottom surface of the parison 2 is cut with a nipper 12. Then this parison is inserted into a stretch-blow-molding machine C, is stretched with a stretching rod 17 up to a given length, the air is blown in, the parison 2 is expanded to mold the transparent vessel.
