The child safety lighter includes a pair of pivoted elements one of which engages a valve stem for moving a valve between closed and opened positions upon pivoting the element by application of thumb pressure to a first finger-engageable surface. The second element includes a second finger-engageable surface extending about the outer periphery of the first surface whereby the two surfaces combined correspond in shape essentially to a typical thumb press pad of a conventional lighter. The second element is independently pivotal against the bias of a spring. Because the first surface area is reduced and located between the second surface and the spark wheel of the lighter, increased force and dexterity is necessary to pivot the first lever to actuate the lighter. |
