GLASS CONTAINERS WITH RESISTANCE TO DELAMINATION AND HIGH RESISTANCE TO DAMAGE Russian patent published in 2019 - IPC B65D1/40 C03C4/20 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to glass containers. Glass body has an inner area extending from approximately 10 nm below the inner surface and having stable homogeneity of the layer such that extreme value of concentration in the layer of each of the components of the glass composition in the inner region is greater than or equal to approximately 80 % or approximately 120 % or less of the concentration of the same constituent component at the middle point of the thickness of the glass body. Also, extreme value of surface concentration of each component in surface area in separate point exceeds or is equal to approximately 70 % and is approximately 130 % or less of the concentration of the same constituent component in the surface region at any other separate point of the inner surface.

EFFECT: increased resistance to peeling and resistance to damage.
