ABSTRACT:
A disposable lighter includes a pushbutton depressible toward a top wall of the lighter's upper end portion to operate a normally closed valve to an open position that releases fuel for ignition by sparks generated by rolling a flintwheel. A spring is added having a U-shaped first portion mounted in a recess in the lighter's upper end portion under the pushbutton. A second portion of the spring extends from a resilient first arm of the first portion and defines a stop member slidably mounted on the top wall under a peg depending from the pushbutton. An actuator part of the second portion projects outwardly of the upper end portion and is pushable inwardly to slide the stop member from an initial position that blocks depression of the pushbutton whereby the valve normally cannot be operated to its open position, to an alternate position wherein an opening in the stop member permits depression of the pushbutton by entry of the peg into such opening. The actuator pushes the stop member against the resistance of the first arm whereby the stop member and actuator are biased to return to their initial position. A first-portion second arm preferably carries a third arm a resilient free end of which holds the stop member at its alternate position until the pushbutton is depressed. Preferably, an obstacle imposes circuitous inward movement of the actuator.
