US Patent 7147463 Lock mechanism for increasing the saftey of a lighter

A child resistant lighter includes a housing having a trigger slideably mounted thereon. A latch, internal to the housing, prevents movement of the trigger and thus prevents ignition of the lighter. A lever is pivotally mounted on the trigger. In one position, the lever is flush with the trigger, and not readily discernable as a lock release mechanism. In a second position, the lever is raised off of the trigger. In the raised position, the lever contacts the latch to slide the latch in a direction that enables movement of the trigger.
