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.

A method of protecting a portion of the surface of a glass bottle in at least one area from scuffing due to contact with bottle handling and filling equipment, other bottles, and bottle containers, comprising the steps of:
- (a) providing a glass bottle defining a circumferential groove in the larger diameter area or areas of said bottle,
- (b) rotating the bottle about a horizontal axis,
- (c) applying uncured plastic liquid to only the said larger diameter area or areas of said bottle by flow coating said plastic liquid into said circumferential groove from a liquid applicator nozzle means, an amount of plastic liquid being applied which is sufficient to fill completely said circumferential groove, and
- (d) curing said plastic liquid to produce a bottle which is protected from scuffing by a circumferential band of plastic material in the area to be protected.
A method of protecting a portion of the surface of a glass bottle in at least one area from scuffing due to contact with bottle handling and filling equipment, other bottles, and bottle containers, comprising the steps of:
- (a) providing a glass bottle having a larger diameter area or areas to be protected,
- (b) priming said bottle,
- (c) preheating the primed bottle,
- (d) rotating the bottle about a horizontal axis,
- (e) applying uncured, thickened, plastic liquid to only said larger diameter area or areas of said bottle surface by flow coating said plastic liquid from a liquid applicator nozzle means,
- (f) rapidly curing said plastic liquid to produce a bottle which is protected from scuffing by a circumferential band of plastic material in the area to be protected.
