  • Patent number: 6669466
    Abstract: The present invention is directed to a utility lighter having a housing, a nozzle, a lighter fluid reservoir, a conduit, an igniter assembly, a valve actuator, and a locking device. The housing has a top side, a bottom side, sides, a distal end, and a proximal end. The nozzle extends away from the distal end and has a nozzle tip. The lighter fluid reservoir is in the distal end. The conduit delivers the lighter fluid from the reservoir through the conduit to the nozzle tip. The igniter assembly generates a spark at a spark gap near the nozzle tip to ignite the lighter fluid, and has a piezoelectric component. The valve actuator is associated with the lighter fluid for selectively releasing the lighter fluid from the reservoir, and the igniter assembly.
