Abstract
A cigarette lighter is disclosed having a body defining a fuel reservoir and a threaded passageway extending from the reservoir to the body exterior. An insert is threaded at least partially into the passageway and a set of bendable tabs secured thereabout along a common plane exteriorly of the body. Stop means are provided for limiting rotary movement of the insert through engagement with a member of the set of bendable tabs bent off the common plane. A valve stem is movably disposed within a cavity in the insert with a portion of the valve stem projecting to the exterior thereof. An actuating lever is coupled with the valve stem and interlocked with a fulcrum.
