Mason jar

In 1858, John Landis Mason received a U.S. patent for his invention known by his name - the Mason jar (No. 22,186). Although hundreds of men and women obtained patents for fruit jars, probably the most well known in the industry has been the Mason jar. It has become a common term for the preserved food jar. Mason developed and patented a shoulder-seal jar with a zinc screw cap. The "Mason jar" had a threaded neck which fit with the threads in a metal cap to screw down to the shoulder of the jar and in this way form a seal. In 1869, a top seal above the threads and under a glass lid was introduced to the jar, thus effecting an excellent seal.[Image: The Gem mason jar, made by Hero Glass Works, Philadelphia, Pennsylvania, circa 1869]
