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 actuation inhibiting mechanism requires a downward displacement and a tilted displacement in order to allow full depression of the actuator and activation of an ignition mechanism. Preferably, at least one biasing element is provided so that when the actuator is displaced through the application of force by a user, it returns to the initial blocking position when the force is removed.
