METHOD FOR ENHANCING THE STRENGTH OF A GLASS CONTAINER AND STRENGTH ENHANCED GLASS CONTAINER

摘要

A method for enhancing the strength of glass containers is presented wherein the containers are preheated to 500 DEG C and coated with the strength enhancement coating within six (6) hours after the heat treatment. In one embodiment, a coating station (26) for the strength enhancing coating is located between the exit from a lehr (18) and a cold end spray station (20). In a second embodiment, the strength enhancing coating station (26) is positioned downstream of the cold end station (20).
