  • Strengthened glass articles with separation features
    Patent number: 11530155
    Abstract: A method of forming a strengthened glass article is provided. The method includes providing a strengthened glass article. The strengthened glass article is in the form of a container including a sidewall having an exterior surface and an interior surface that encloses an interior volume. The sidewall has an exterior strengthened surface layer that includes the exterior surface, an interior strengthened surface layer that includes the interior surface and a central layer between the exterior strengthened surface layer and the interior strengthened surface layer that is under a tensile stress. A laser-induced intended line of separation is formed in the central layer at a predetermined depth between the exterior strengthened surface layer and the interior strengthened surface layer by irradiating the sidewall with a laser without separating the glass article.
