Mason jar is a kind of glass jar with cover originated from the United States. The juice, jelly and milkshake contained in mason jar are popular all over the world because of their health and delicious, changeable shapes and full of literary style. Mason jar was born in the 1850s. It was invented by John Landis Mason, a blacksmith from Philadelphia, USA, and patented in 1858.
Mason jar is made of thick glass can body. It pioneered the threaded bottle mouth. The special cover is composed of a metal sheet and a threaded ring belt. The vacuum in the can can can be realized at the moment of locking, instead of the troublesome practice of using cork and sealing wax to prevent corrosion. Of course, transparent glass also helped people see the changes in the can in time and clearly, which solved the difficult problem of fruit storage in many families at that time.
