Abstract
Delamination resistant glass containers with heat-tolerant coatings are disclosed. In one embodiment, a glass container may include a glass body having an interior surface, an exterior surface and a wall thickness extending from the exterior surface to the interior surface. At least the interior surface of the glass body is delamination resistant. The glass container may further include a heat-tolerant coating positioned on at least a portion of the exterior surface of the glass body. The heat-tolerant coating may be thermally stable at temperatures greater than or equal to 260° C. for 30 minutes.

20. A glass container comprising:
-
a glass body having an interior surface and an exterior surface, wherein at least the interior surface of the glass body has a delamination factor of less than or equal to 10; and a heat-tolerant coating bonded to at least a portion of the exterior surface of the glass body, wherein the exterior surface of the glass body with the heat-tolerant coating has a coefficient of friction of less than about 0.7, wherein the coefficient of friction is a maximum coefficient of friction measured relative to a second glass container in a vial-on-vial testing jig under a normal load of 30 N, the second glass container having a body formed from a same glass composition and comprising the heat-tolerant coating on an at least a portion of the outer surface of a body of the second glass container and subjected to the same environmental conditions prior to measurement. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
