Abstract
A forming mold is used when forming a preform, which has a neck portion and a barrel portion, and whose barrel portion is filled with a molding material over the entire axial direction thereof, by injection molding; forming a space part in the barrel portion of the preform to convert the preform into an intermediate molded product; and blow-molding the intermediate molded product to form a hollow container which is a final molded product. The forming mold is equipped with a boring rod which is inserted from the neck portion side into the barrel portion of the preform to form the space part of at least a predetermined depth in the barrel portion.
