Method and apparatus for producing bottle-type synthetic resin containers
CA 2452116 A1
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 200C to 230C 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 170C to 195C in the case of polyethylene terephthalate resin.
