Abstract
A disposable cigarette gas lighter has a snuffing cover on a plastic fuel reservoir. The snuffing cover is rotatably mounted on the lighter independently of a sparking wheel. When lighting the lighter, the snuffing cover is opened with the thumb which is used for rotating the sparking wheel so that the snuffing cover will be opened when the sparking wheel is rotated. When closing the snuffing cover, the snuffing cover is closed independently of the sparking wheel. Further, the snuffing cover can be opened without rotating the sparking wheel so that the sparking wheel is not rotated when the snuffing cover is accidentally opened.
