ABSTRACT:
This invention decreases the time required to cool a plastic article, in a blow molding cavity, by circulating a mist in the inside of the blown article. Globules of liquid in the mist contact with the inside surface of the blown article. Preferably this liquid evaporates and removes its latent heat evaporization from the plastic surface. This removes more heat per unit of time than is removed with a breeze of dry air flowing in the blown article. The article is cooled so that it is stiff enough to remove sooner from the blow mold. The mist can be followed by dry air to remove any lingering liquid from a blown container.
