Abstract
An improved selectively actuatable child resistant lighter device is disclosed which includes a body defining reservoir for containing a combustible gaseous medium such as butane, and having a valve arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. A locking mechanism normally prevents actuation of the valve to the open position. Such child resistant lighter device embodies a resiliently releasable locking latch which prevents movement of a fuel nozzle from a first, or fuel cutoff, position to a second, or fuel flow, position. The locking latch is selectively movable to an unlocked position in which depression of a valve actuator causes the fuel nozzle to move from the fuel cutoff position to the fuel flow position, so that the gaseous medium may be released and ignited by the sparks. The locking latch is resiliently structured and mounted such that once a flame is produced and the valve actuator is released, the locking latch returns to its closed or locked position to prevent actuation of the valve to the open position. To "re-use" the lighter, the locking latch must again be moved to the unlo…
