Abstract:
A cigarette lighter has a removable fuel cartridge with a reservoir for holding flammable liquid fuel, a valve for controlling the flow of fuel into and from the reservoir, an ignition actuator for causing ignition of the fuel, a nozzle for causing the ignited fuel to form a lighting flame, and a valve actuator that cooperates with the ignition actuator to open the valve as the ignition actuator is actuated. The reservoir has a transparent portion which is aligned with a window in the lighter housing to allow external observation of the fuel level in the reservoir. The transparent portion includes indicia for gauging the amount of fuel. The indicia is structurally contoured to provide means for engaging the reservoir to remove the fuel cartridge from the lighter.
