ABSTRACT:
A gas lighter with a safety device which is composed of a lock lever and a resilient leaf. The resilient leaf is defined, on the upper portion of a lighter body and on the path of a depressible actuating means, by a pair of slits formed parallel to each other and longitudinally. The resilient leaf, which is slidably surrounded with the lock lever, is at the upper end thereof incurved towards the lighter body. When the lock lever is positioned at the lowermost end of the slits, i.e., a locked position, the incurved portion of the resilient leaf is engaged with a recess at the lowermost end of the actuating means, thereby preventing the depression of the actuating means. When the lock lever is thrust uppermost along the slits, i.e., up to an unlocked position, the incurved end of the resilient leaf is forcibly straightened, whereby the disengaged actuating means can be depressed.
