Glass containers with delamination resistance and improved strength
First Claim
1. A glass container comprising:
- a glass body having an inner surface, an outer surface and a wall thickness extending between the outer surface and the inner surface, wherein at least the inner surface of the glass body has a delamination factor less than or equal to 10; and
a compressively stressed layer extending from the outer surface of the glass body into the wall thickness, the compressively stressed layer having a surface compressive stress greater than or equal to 150 MPa.

Abstract
The glass containers described herein have at least two performance attributes selected from resistance to delamination, improved strength, and increased damage resistance. In one embodiment, a glass container with resistance to delamination and improved strength may include a body having an inner surface, an outer surface and a wall thickness extending between the outer surface and the inner surface. At least the inner surface of the body may have a delamination factor less than or equal to 10. The glass container may further include a compressively stressed layer extending from the outer surface of the body into the wall thickness. The compressively stressed layer may have a surface compressive stress greater than or equal to 150 MPa.

41. A glass container comprising:
-
a body having an inner surface, an outer surface and a wall thickness extending between the outer surface and the inner surface, wherein at least the inner surface of the body is formed from a Type I, Class B glass according to ASTM Standard E438-92; a compressively stressed layer extending into the wall thickness, the compressively stressed layer having a surface compressive stress greater than or equal to 150 MPa; and a barrier coating positioned on the inner surface of the body such that a composition contained in the glass container contacts the barrier coating and not the inner surface of the body. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51)

52. A glass container comprising:
-
a body having an inner surface, an outer surface and a wall thickness extending from the outer surface to the inner surface, wherein the body is formed from a glass composition which is free from constituent components which form species that volatilize significantly at temperatures corresponding to a viscosity in a range from about 200 poise to about 100 kilopoise; and a compressively stressed layer extending from the outer surface of the body into the wall thickness, the compressively stressed layer having a surface compressive stress greater than or equal to 150 MPa. - View Dependent Claims (53, 54, 55, 56, 57)
