Glass containers with improved strength and improved damage tolerance

A coated borosilicate glass pharmaceutical package comprising:

• a body formed from a borosilicate glass body having a Type 1 chemical durability according to USP 660, the body having an interior surface and an exterior surface and a wall extending therebetween;
• and
• a lubricous coating having a thickness of less than or equal to 90 nm positioned on at least a portion of the exterior surface but not on any portion of the interior surface, the lubricous coating comprising a polymer, wherein:
• the portion of the exterior surface of the coated borosilicate glass pharmaceutical package with the lubricous coating has a coefficient of friction of less than or equal to 0.6 relative to a like-coated borosilicate glass pharmaceutical package formed from the same glass composition after a depyrogenation cycle comprising exposure to a temperature of 250° C. for a time period of 30 minutes;
• and
• a light transmission through the portion of the exterior surface of the coated borosilicate glass pharmaceutical package is greater than or equal to about 55% of a light transmission through an uncoated borosilicate glass pharmaceutical package formed from the same glass composition for each wavelength from about 400 nm to about 700 nm after the depyrogenation cycle.

A coated glass pharmaceutical package comprising:

• a glass body having a Type 1 Class glass composition according to ASTM Standard E438-92 wherein the glass composition has at least a class A2 base resistance or better according to ISO 695, at least a type HGB2 hydrolytic resistance or better according to ISO 719 and a Type 1 chemical durability according to USP <660>,
• the glass body having and an interior surface and an exterior surface and a wall extending therebetween;
• and
• a lubricous coating having a thickness of less than or equal to 90 nm positioned on at least a portion of the exterior surface but not on any portion of the interior surface, wherein:
• the portion of the exterior surface of the coated glass pharmaceutical package with the lubricous coating has a coefficient of friction that is at least 20% less than an uncoated glass pharmaceutical package formed from the same glass composition;
• a horizontal compression strength of the coated glass pharmaceutical package is at least 10% greater than an uncoated glass pharmaceutical package formed from the same glass composition;
• and
• the coefficient of friction of the coated glass pharmaceutical package is a maximum coefficient of friction measured relative to a second coated glass pharmaceutical package in a vial-on-vial testing jig under a normal load of 30 N, the second coated glass pharmaceutical package formed from the same glass composition and comprising the lubricous coating on at least a portion of a second exterior outer surface of the second coated glass pharmaceutical package and subjected to the same environmental conditions prior to measurement,
• wherein the lubricous coating is a polymer.
