About Owens-Illinois
Owens-Illinois Glass Company was formed in 1929 when the Owens Bottle Company combined with the Illinois Glass Company. The business brought together major producers associated with Toledo, Ohio, and Alton, Illinois. Its predecessors had helped develop the automatic manufacture of glass containers, allowing large quantities of bottles and jars to be made with consistent shapes. The combined company adopted a mark joining the Illinois diamond with an oval and central I.
The company produced containers for drinks, medicines, food and household products across an extensive factory network. Plant and date codes often accompany the manufacturer’s emblem, although their position and interpretation vary with the type of bottle. Duraglas, introduced in 1940, identified a stronger glass formula. Its script wordmark appears on many surviving containers alongside the company logo. An I within an oval began replacing the diamond design in 1954, but older moulds remained in use for years.
In 1965 the corporate name became Owens-Illinois, Inc., reflecting a business that had diversified beyond its original container operations. The acquisition of Brockway in 1988 expanded the glass business, and later international acquisitions widened its manufacturing network. The joined O-I logo became another familiar identification mark. A corporate restructuring in January 2020 created O-I Glass, Inc. Bottle bases therefore preserve several generations of branding rather than one universal mark.
