No international sales. SOME HISTORY: Clamped Glass-Lid Jars (Lightning Jars)
In 1882, Henry William Putnam of Bennington, Vermont, invented a fruit jar that used a glass lid and a metal clamp to hold the lid in place. These "Lightning jars" became popular because no metal (which could rust, breaking the seal or contaminating the food) contacted the food and the metal clamps made the lids themselves easier to seal and remove (hence the "Lightning" name).Alexander H. Kerr founded the Hermetic Fruit Jar Company in 1903 and among the first commercial products were the Economy and Self Sealing jars. The Economy jars were the first wide-mouth jars, and easy to fill. They also incorporated aspects from two 1903 patents held by another inventor, Julius Landsberger: a metal lid with a permanently attached gasket. This made the lids easy to use and inexpensive. Mr. Kerr later (1915) invented a smaller, flat metal disk with the same permanent composition gasket. The lid sealed on the top of a mason jar; a threaded metal ring held the lid down during the hot water processing. This allowed re-use of old canning jars together with inexpensive and easy to use disposable lids. The jar we know today was born! This two-part lid system transformed home canning safety and is still in use today.
