Abstract
A lighter of the disposable type, ignition of which requires depression of an actuator that is resistant to the manipulations of unintended users. The lighter is normally maintained in a position that prevents depression of the actuator through the incorporation of a mechanism that increases the difficulty of operation. The safety mechanism requires a tilted displacement in order to allow full depression of the actuator and activation of an ignition means. When the mechanism is so displaced through the application of force by a user, it cannot remain displaced without continuous application of such force and will return to the normal, blocking, position when the force is removed.
