A child resistant roll-and-press lighter includes at least one abutment surface (32; 41; 45) which engages a corresponding counterabutment surface (33; 42; 44) on the lever (20; 50, 51). The surfaces disengage to release the lever for pivotal movement, when and only when at least a predetermined minimum force is applied to the lever pad (23) by the user. The abutment or counterabutment surface may be arranged on a transversely deformable, resilient engaging element (30; 43; 46) which engages the corresponding surface in tension. Alternatively the lever may be mounted in elongate slots so as to translate and so disengage the cooperating surfaces when the minimum force is applied by the user. Alternatively the counterabutment surface may be arranged on a sliding catch (51) housed beneath the lever pad. The minimum force is easily applied by the adult user by rotating the wheel assembly (10) at normal speed.
