ABSTRACT:
Improved apparatus for coating glass containers provides a coating on the body for improved resistance to impact breakage and abrasion, while coating of threads or lugs at the open tops of the containers is limited to about one-tenth, or less, of the coating on the surfaces of the body, which surfaces are exposed to contact with other containers during handling. The apparatus provides a laminar flow of fluid which is free of coating-precursor chemical over the threads or lugs in a manner which minimizes turbulence and intermixing with the coating stream.
