Abstract
A post-molding cooling apparatus directs a stream of cooling fluid against a concave interior surface of a molded article to cool the molded article. The apparatus includes an outlet positioned to direct the stream of cooling fluid into an open end of the molded article. The interior surface of the molded article is concave. The outlet is configured to direct the stream of cooling fluid in a helical direction such that at least a portion of the concave interior surface of the molded article acts as a curved surface relative to a direction of flow of the stream of cooling fluid to create turbulent flow of the stream of cooling fluid against the concave interior surface of the molded article along a length of the concave interior surface from the open end of the molded article toward a closed end of the molded article.
