Abstract
A safety lighter is disclosed. The lighter comprises a lighter body, a nozzle, a mounting frame disposed on the lighter body, and an actuating lever which is reciprocatingly mounted on the mounting frame between forward and rearward positions. The front end of the lever grips the nozzle and moves it from its lower position, where gas cannot escape from said nozzle, to the nozzle's upper position where gas is ejected from said nozzle. The rear end of the lever has a downwardly extending projection which can be received into a recess in the top of the lighter body when the lever is in the forward position. When the lever is in the rearward position and the rear end of the lever is pressed downward, its projection comes into vertical engagement with the top of the lighter body, which prevents the lever from pivoting far enough to lift the nozzle. In a preferred embodiment a spring is disposed in the recess, which spring acts to urge the lever rearward and also acts to urge the rear end of the lever to pivot upward.
