ABSTRACT:
The invention includes a child-resistant mechanism for a utility lighter. The child-resistant mechanism includes an operation member for activating the piezoelectric unit. The operation member has an inoperable position and an operable position. Attached to the back side of the operation member is a horizontal lever for activating the fuel-release lever as the operation member is moved into the operable position then depressed in one motion by the finger of a user. A spring, attached to the horizontal lever, urges the operation member into the inoperable position. Further the horizontal lever cannot activate the fuel-release lever as the operation member is depressed while in the inoperable position because the horizontal lever and the fuel-release lever are not aligned.
