Disposable lighter with child resistant device
A child resistant device, incorporated with a disposable lighter, includes a pair of shelter wheels, each having a U-shaped cross section, supported on two sides of two driving wheels respectively and partially covering circumferential teeth surfaces of the two driving wheels respectively to define an actuating edge at an uncovered portion of the circumferential teeth surface of each of the driving wheels. Therefore, the disposable lighter only allows an adult's thumb to press on the shelter wheels until the surface skin of the adult's thumb contact with the actuating edges to rotate the driving wheels so as to ignite the disposable lighter.
