ABSTRACT:
A child-resistant lighter includes a pushbutton depressible toward an upper end portion of the lighter body to operate a normally closed valve to an open condition that releases a combustible gas for ignition by sparks produced by means operated when the pushbutton is depressed. Wall members spaced apart on the upper end portion define a slot at a rearward end of the upper end portion. A stop member slidable longitudinally on the upper end portion includes a blocking member that normally blocks depression of a lower surface of the pushbutton whereby it is normally locked. A neck portion of the stop member extending through the slot has a projecting end defining an actuator having resilient arm members having free ends slidably engaged with outboard surfaces of the wall members such that the arm members flex when the actuator is pushed inwardly toward the slot and a longitudinally-directed return bias is thereby imparted to the actuator. Pushing the actuator first inwardly and then upwardly moves the blocking member first longitudinally inwardly removed from the pushbutton's lower surface and then into a resiliently maintained frictional contact with an inner side of the pushbutton whereby the pushbutton is unlocked. Depression of the pushbutton depresses the blocking member and after release of the pushbutton the blocking member is returned under the pushbutton's lower surface by the return bias of the actuator.
