A lighter 1 comprises a fuel container 2, a wick 3, a valve arrangement 4 comprising a valve 5 and an annular flange 6, a spring 10 biasing a flint 9 into contact with a sparking wheel 10, and a lever 14 pivoting on axles 16 in a groove 20 and is moveable between a valve operating and non-operating position. Groove 20 comprises a distorted Y-shape with a first end 21, second end 22 and a third end 23. Lever 14 has a thumb end 17, webs 27 either side of a formation 30 and an operating end 15 comprising a portion 28 which is larger than the flange 6 and a portion 29 which is smaller than the flange6. When lever 14 is depressed it contacts structure 19 so that valve 5 is not operated and only when lever 14 is laterally pushed in so that the axles 16 move to the second end 22 and then depressed so that axles 16 move to the third end 23 does the portion 29 engage flange 6 and permit valve 5 to be lifted and fuel to flow. When the pressure is released, lever 14 returns to the valve non-operating position where axle 16 is located at the first end 21. Spring 10 maybe different types of coil spring (fig 10) or a bent flat strip (fig 11). The lighter may have a wind shield 21. Groove 20 maybe of different shapes (figs 8, 9). |
