CONTAINERS OF A STRENGTHENED BOROSILICATE GLASS WITH INCREASED DAMAGE TOLERANCE Russian patent published in 2017 - IPC C03C17/28 C03C21/00 C03B27/00 

FIELD: packaging industry.

SUBSTANCE: housing formed of a glass composition of Type I, Class B, in accordance with standard ASTM E438-92, the housing having HGB2 hydrolytic resistance class or higher according to ISO 719. Casing glass container is strengthened by ion exchange. On the outer surface of the housing is located a smooth coating the organic layer. The outer surface of the housing with a smooth coating layer has a friction coefficient of less than or equal to 0.7. The coating layer is thermally stable at a temperature of at least about 260°C for 30 minutes.

EFFECT: increased resistance to delamination, damage, increase the strength of the glass container.
