ABSTRACT:
A child-resistant disposable lighter relies for its effectiveness on differences in the ways young children and adults think rather than on presumed (but often non-existent) strength or dexterity differences. The child-resistant feature comprises a combination lock mechanism that incorporates at least one directly manipulated member, and, in some embodiments, at least one indirectly movable member. Some embodiments incorporate a feature that arrests rotation of the spark wheel when the thumb lever is locked in the child-resistant condition.
