A lighter is a portable device used to generate a flame.
It consists of a metal or plastic container filled with a flammable fluid or pressurized liquid gas, a means of ignition, and some provision for extinguishing the flame.
A typical form of lighter is the permanent match, consisting of a fuel-filled metal shell and separate metal rod serving as wick.
The rod is removed and scratched against a flint on the side of the case to create a spark. Its internal wick catches fire, resembling a match.
The flame is extinguished by placing the rod into the shell, where it absorbs fuel for the next use.
