Kilner jar
A Kilner jar is a jar that has a rubber ring to seal the top. It does not let out any air, and helps to store food. It was invented by the Kilner family and made by John Kilner & Co in Yorkshire, England. Most jars made now-a-days have metal tops instead of rubber. They are also known as Terrine Jars.
