ABSTRACT:
A method of protecting at least one portion of the surface of a glass bottle from scuffing due to contact with bottle handling and filling equipment, other bottles, and bottle containers, comprises the step of providing a glass bottle defining a circumferential groove in the area to be protected. The bottle is rotated about a horizontal axis and an uncured plastic liquid is applied to the bottle surface by flow coating the plastic into the circumferential groove. An amount of plastic liquid is applied which is sufficient to fill completely the circumferential groove. The plastic liquid is then cured to produce a bottle which is protected from scuffing by a circumferential band of plastic material in the area to be protected.
