Kilner jar

A Kilner jar is a rubber-sealed, glass jar used for preserving (bottling) food.

It was first produced in 1900 by John Kilner & Co., Yorkshire, England.

[1][2][3] The Kilner Jar was originally invented by John Kilner (1792–1857) and associates,[4] and made by a firm of glass bottlemakers from Yorkshire called Kilner which he set up.

[5] The original Kilner bottlemakers operated from 1842, when the company was first founded, until 1937, when the company went into liquidation.

In 2003,[6] The Rayware Group purchased the Ravenhead name, including the design, patent and trademark of the original Kilner jar[dubious – discuss] and continues to produce them today in China.
