ABSTRACT:
A method for producing bottle-type containers made of a synthetic resin, e.g., polyethylene-terephthalate resin, includes a heat treatment step for heating and crystallizing a neck portion of a perform corresponding to a neck portion of a container. In a first stage of the heat treatment step, the neck portion of the perform is temporarily heated to a temperature below a melting point of the synthetic resin, e.g., approximately 200° C. to 230° C. in the case of polyethylene terephthalate resin. In a subsequent second stage, the neck portion is maintained at a temperature within a range in which crystallization of the synthetic resin is promoted, e.g. approximately 170° C. to 195° C. in the case of polyethylene terephthalate resin.
