Abstract

A method for treating hot glass containers that are moved through a treatment zone. The treatment zone is a system which utilizes heated compressed air aspirators rather than electric motor driven blowers to cause a treatment vapor laden air contained in chambers to be propelled across the width of the ware conveyor from both sides at adjacent, horizontally spaced, points in the conveyor length. The resultant streams of heated air and vapor laden air will impinge on the containers carried on the conveyor and are of a size to cover the container height to about the shoulder. The vapor and air that passes the containers from one direction is captured and fed to the chamber for feeding in the other direction. Thus the vapor laden air is recirculated from side to side with additional concentrated treatment vapors introduced to maintain a certain level of tin or titanium in the vapors so as to produce the metal oxide coating on the containers. In addition, streams of air propelled by heated compressed air aspirators rather than motor driven blowers sweep across the finish portion of the container immediately above the vapor laden streams to effectively keep the metal oxide coating from forming on the threads or finish of the container.
