The fuel, light petroleum distillate or synthetic isoparaffinic hydrocarbon (commonly referred to as lighter fluid or naphtha), is poured into the ball, which absorbs it.It also contains a tube that holds a short, cylindrical flint.On June 5, 2012, the company manufactured its 500,000,000th lighter as well as celebrated its 80th anniversary.
and Private First Class Reginald "Malik" Edwards, the rifleman 9th Regiment, US Marine Corps Danang (June 1965-March 1966) whose profile comprises chapter one of Wallace Terry's book, Bloods: An Oral History of the Vietnam War by Black Veterans (1984), describe the use of Zippo lighters in search and destroy missions during the Vietnam War. On the left of the underside was stamped a letter A–L, denoting the month (A = January, B = February, C = March, etc.).
Edwards stated: "when you say level a village, you don't use torches. On the right was a Roman numeral which denoted the year, beginning with II in 1986.
Thousands of different styles and designs have been made in the eight decades since their introduction including military versions for specific regiments.
Since its invention Zippos have been sold around the world and have been described "a legendary and distinct symbol of Americana".
The cases of Zippo lighters are typically made of brass and are rectangular with a hinged top.
On most models, the top of the case is slightly curved.
Much of the early Zippo lighter advertising are works of art painted by hand, and as technology has evolved, so has the design and finish of the Zippo lighter.
The basic mechanism of the Zippo lighter has remained unchanged.
A consequence of the windproofing is that it is hard to extinguish a Zippo by blowing out the flame. It was for burnin' shit down." All Zippo windproof lighters carry an unlimited lifetime guarantee, promoted using the trademarked phrase "It works or we fix it for free." The corporate web site boasts: "in almost 75 years, no one has ever spent a cent on the mechanical repair of a Zippo lighter regardless of the lighter’s age or condition." In mid-1955, Zippo started year coding their lighters by the use of dots.
However, if the flame is blown from the top down, it will be easily extinguished. From 1966 until 1973 the year code was denoted by combinations of vertical lines.
Since its inception Zippo Lighters have been almost exclusively manufactured in the United States, with the exception of those manufactured in Niagara, Canada (an operation that has since been shut down). Blaisdell founded Zippo Manufacturing Company in 1932, and produced the first Zippo lighter in early 1933, being inspired by an Austrian cigarette lighter of similar design made by IMCO.
