GLASS CONTAINERS WITH IMPROVED STRENGTH AND IMPROVED RESISTANCE TO DESTRUCTION Russian patent published in 2019 - IPC B65D1/40 C03C17/00 C03C21/00 

FIELD: package and storage.

SUBSTANCE: invention relates to a glass pharmaceutical package. Package is a glass container having an inwardly facing surface, an outer surface and a wall extending therebetween, wherein the glass container is formed from one of the borosilicate glass composition corresponding to Type 1 criteria according to USP <660>, or alkali aluminosilicate glass having hydrolytic resistance of HGA1 class when analyzed in accordance with ISO 720; and slippery coating having thickness less than or equal to 100 mcm and located on at least part of outer surface. Part of the outer surface of the glass pharmaceutical package with a slippery coating has a friction coefficient that is at least 20 % less than the friction coefficient of the glass pharmaceutical package without coating, and coefficient of friction does not increase by more than 30 % after depyrogenation cycle. Compressive strength of a portion of the outer surface of the glass pharmaceutical package with a slippery coating is at least 10 % greater than that of the uncoated glass pharmaceutical package, and the strength at horizontal compression does not decrease by more than 20 % after the depirogenation cycle.

EFFECT: high resistance to delamination, strength and resistance to breakage.
