The Kilner Jar was originally made by a firm of glass bottlemakers from Yorkshire called Kilner. The original Kilner bottlemakers, operated from 1842 when the company was first founded until when 1937 when the company went into bankruptcy. The Kilner Company was taken to court in 1871 over the coal smoke coming from their Thornhill Lees chimneys and the Judge ordered that "no man has the right to interfere with the supply of pure air". The company was forced to close down to convert to gas furnaces and struggled along for a few years despite 3,000 people losing their jobs. In 1937 there was a bankruptcy sale, in which the patent rights to the "Kilner Jar" were sold to the United Glass Bottle company along with the rights to the very similar "Mason" jar that had also been made by Kilner.
In 2000, The Rayware Group purchased the design, patent and trademark of the original Kilner jar and continues to produce them today.
