Glass packaging ensuring container integrity
A strengthened glass container or vessel such as, but not limited to, vials for holding pharmaceutical products or vaccines in a hermetic and/or sterile state. The strengthened glass container undergoes a strengthening process that produces compression at the surface and tension within the container wall. The strengthening process is designed such that the tension within the wall is great enough to ensure catastrophic failure of the container, thus rendering the product unusable, should sterility be compromised by a through-wall crack. The tension is greater than a threshold central tension, above which catastrophic failure of the container is guaranteed, thus eliminating any potential for violation of pharmaceutical integrity.
STRESS FEATURES FOR CRACK REDIRECTION AND PROTECTION IN GLASS CONTAINERS
A glass container comprises a glass body comprising a first region under a compressive stress extending from a surface of the glass body to a depth of compression and a second region extending from the depth of compression into a thickness of the glass body, the second region being under a tensile stress. The glass container also includes a localized compressive stress region having a localized compressive stress extending from the surface to a localized depth of compression within the body. The localized depth of compression is greater than the depth of compression of the first region. The glass container also includes a crack re-direction region extending in a predetermined propagation direction, wherein the crack re-direction region possesses a higher tensile stress than the tensile stress in the second region in a sub-region of the crack re-direction region, the sub-region extending substantially perpendicular to the predetermined propagation direction.

DRINKING IMPLEMENT WITH IMPROVED BREAKING STRENGTH AND MOUTH FEEL
A drinking implement includes a first end section with a first opening and a second end section with a second opening. A wall made of glass extends from the first opening to the second opening. At least one of the first end section or the second end section is designed as a specific end section having at least partially a ridge, an outer edge, and an inner edge. An outer transition angle and an inner transition angle both have absolute values of less than 90 degrees.

Damage-resistant glass articles and method
A strengthened glass article has opposing first and second compressively stressed surface portions bound to a tensilely stressed core portion, with the first surface portion having a higher level of compressive surface stress than the second surface portion for improved resistance to surface damage, the compressively stressed surface portions being provided by lamination, ion-exchange, thermal tempering, or combinations thereof to control the stress profiles and limit the fracture energies of the articles.
DRINKING IMPLEMENT WITH HIGH STRENGTH
A drinking implement includes: a first opening; a lumen; a second opening fluidly coupled to the first opening and the lumen; and a wall including a glass and extending from the first opening to the second opening and surrounding the lumen. The wall has an inner surface facing toward the lumen and an outer surface facing away from the lumen. The wall has a first compressive stress layer extending from the inner surface to a first depth within the wall, a second compressive stress layer extending from the outer surface to a second depth within the wall, and a tensile stress layer disposed within the wall at a depth between the first compressive stress layer and the second compressive stress layer. The second depth is from 0.05% to 25% of a thickness of the wall.
Pharmaceutical glass packaging assuring pharmaceutical sterility
A sterile glass pharmaceutical container or vessel such as, but not limited to, vials for holding pharmaceutical products or vaccines in a hermetic and/or sterile state. The sterile glass pharmaceutical container undergoes a strengthening process that produces compression at the surface and tension within the container wall. The strengthening process is designed such that the tension within the wall is great enough to ensure catastrophic failure of the pharmaceutical container, thus rendering the product unusable, should sterility be compromised by a through-wall crack. The tension is greater than a threshold central tension, above which catastrophic failure of the pharmaceutical container is guaranteed, thus eliminating any potential for violation of pharmaceutical integrity or sterility (such as stable cracks) in the glass packaging which are not easily identifiable in an otherwise seemingly intact pharmaceutical container.
