Claims: What is claimed is:

1. A method for completely enclosing two contiguous regions of a glass container which comprises the steps of:

providing a reservoir having formed thereon a doctoring edge having a radius of curvature substantially corresponding to the radius of curvature of a first region of said glass container, said reservoir containing molten organic polymeric material extending said reservoir containing said molten material from a remote location to a location adjacent said first region of said glass container after said glass container is at a coating application station;

supplying molten organic polymeric material to said reservoir at a flow rate sufficient to maintain said reservoir in a substantially overflow condition at the time of extension from said remote location;

contacting said first region of said glass container with said overflowing organic polymeric material;

flowing said molten organic polymeric material direectly from the reservoir onto said first region of said glass container and simultaneously doctoring said flowing material by moving said reservoir and said glass container relative to one another through 360.degree. with respect to the circumference of said glass contaner while said glass container is in contact with said overflowing organic polymeric material to thereby cause said first region to be completely enclosed with a substantially uniform layer of said organic polymeric material;

retracting said reservoir to said remote location after said relative 360.degree. movement has taken place;

placing a hollow tubular member of a contractable thermoplastic material around the second region of said glass container; and

contracting said thermoplastic tubular member into a snug fitting conforming engagement with said second region of said glass container to thereby completely enclose said second region.

2. The method of claim 1 wherein the step of placing a hollow tubular member around the second region includes the step of:

abutting said hollow tubular member with a marginal edge of said layer of organic polymeric material.

3. The method of claim 1 wherein the step of placing a hollow tubular member around the second region includes the step of:

overlapping a portion of a marginal edge of said layer of organic polymeric material with said hollow tubular member.

4. A method for enclosing a localized region of a glass container with a layer of an organic polymeric material which comprises the steps of:

providing a reservoir having formed thereon a doctoring edge having a radius of curvature subtantially corresponding to the radius of curvature of said localized region, said reservoir containing molten organic polymeric material;

positioning said reservoir containing said molten organic polymeric material in a location adjacent to said localized region;

supplying molten organic polymeric material to said reservoir at a flow rate sufficient to maintain said reservoir in a substantially overflow condition;

contacting a portion of said localized region of said glass container with said overflowing organic polymeric material;

flowing said molten organic polymeric material directly from the reservoir onto said localized region of said glass container by moving said reservoir and said glass container relative to one another through 360 degrees with respect to the circumference of said glass container while said glass container is in contact with said overflowing organic polymeric material;

simultaneously with the flow of organic polymeric material onto said localized region, doctoring said flowing organic polymeric material to thereby completely enclose said localized region with a substantially uniform layer of said organic polymeric material; and

retracting said reservoir to a location remote from said glass container after said relative 360.degree. movement has taken place.
