1947:
The first gas fueled lighter, the Gentry - a table lighter, is introduced by the Quercia family owned Flaminaire Company and is shortly followed by a pocket model called the Crillion. An identical lighter was marketed under license in the USA by the Parker Pen Company - the Parker Flaminaire in the 1950s. The early butane lighters all used proprietary single use gas tanks. When the tank was empty, you bought another one - a good revenue stream for the manufacturers. Later this evolved to a system of refillable tanks that used proprietary cylinders to fill them - you had to buy the right gas cylinder for your lighter. A little further on butane gas could be bought from third party manufacturers - who often included adapters so you could refill any of several brands of lighters. Eventually almost all butane lighters used standardized filler mechanisms. In some cases, it is possible to still get the old lighters and work on the tanks to make them refillable and end up with a working lighter.
1961:
The French Samec Company introduces the first disposable butane lighter - the Cricket. The disposable lighter was to have almost as much a transforming effect on the lighter industry as the flint because it ushered in a new age of very cheap, disposable lighters and effectively put most of the makers of durable lighters out of business over a period of time. Cricket was acquired by Gillette (safety razors / blades) in 1970 and introduced in the USA in 1972.
1962:
The first patent application for a piezoelectric lighter is submitted by Sapphire-Molectric - a subsidiary of Colibri - and designed by Hans Lowenthal and Martin Paul Levy. The second patent was submitted in Japan in 1964 by Mansei Koyo. The first piezoelectric to hit the market was the Maruman Business Table Lighter in 1966. The Colibri Moletric 80 was the earliest pocket size piezoelectric lighter - the Molectric 88, which came out 2 years later, is also pictured. This ushers in the piezoelectric ignition that replaces flint and a host of piezoelectric lighters in the mid-1960s through the 1970s. Still very much in use, they are no longer as common as they once were. The name 'piezo' derives from the Greek 'piezen' meaning 'to press'. A piezoelectric device consists of a small, spring-loaded hammer which, when a button is pressed, hits a crystal of PZT or quartz crystal. Quartz is piezoelectric, which means that it creates a voltage when deformed. This sudden forceful deformation produces a high voltage and subsequent electrical discharge, which ignites the gas. The discovery of and earliest research on the phenomenon of piezoelectricity was in the mid-1800s. Many synthetic materials have also been produced to generate the piezoelectric effect.
