Beschreibung
Zusammenfassung:	PURPOSE:To obtain the titled container with efficiently increased impact resistance by forming the 1st compressive stress layers on the inner and outer surfaces of a glass container by rakpid cooling and by superposing the 2nd compressive stress layer with a higher ion exchange rate on the inner surface and the 3rd compressive stress layer with a lower ion exchange rate on the outer surface. CONSTITUTION:This glass container holds a double layer consisting of the 1st compressive stress layer provided by rapid cooling and the 2nd compressive stress layer with a higher ion exchange rate on the inner surface and a double layer consisting of the 1st compressive stress layer provided by rapid cooling and the 3rd compressive stress layer with a lower ion exchange rate on the outer surface. An applicable glass container is made of soda lime silica glass in general, and the preferred stress value of the 1st compressive stress layers obtd. by rapid cooling is 100-750kg/cm . K salt is used as alkali salt for ion exchange. The preferred average thickness of the body of the container is 1.0-2.5mm.. This container has superior strength to external force such as contact and an impact applied to the outer surface.
