ABSTRACT:
A child-resistant lockable lighter has an actuating lever which can be slid to and fro between a locked position and a released position. In its released position, the lever is pivotable for opening a gas valve. In its locked position, the lever is prevented from pivoting and, also is wedged against the side wheels of the spark wheel so as to prevent rotation of the spark wheel. The pulling force required to displace the locking lever from its locked position to its released position is greater than that which can be exerted by a child.
