John Kilner (1792-1857) invented the Kilner jar along and later founded the John Kilner & Co glass company in 1842. Although enjoying success, rival glass manufacturers quickly started to produce similar items causing the Kilner family business to go bankrupt in 1937. The patents and trademarks of the Kilner Jar were sold to the United Glass Bottle Company where more modern Kilner jars are still being produced today.
