ABSTRACT:
A lighter has few moving parts. A lid assembly which closes a fuel supply and which rotates a flint wheel can be controlled by the same spring or other resilient means which bears a flint against the flint wheel. The lid assembly has one or more cams which bear against cam guides; the shape of these cams and guides are such that the spring produces a turning moment on the lid assembly which keeps the lid assembly closed when in the closed position and open when in the open position. A second spring can be provided, thereby increasing the turning moment on the lid assembly without increasing friction between the flint and the flint wheel. The cam guides can be formed as part of the body of the lighter, guides, or they can be provided in a separate structure housed within the lighter body, guides.
