A disposable gas lighter of the butane-fuel type comprises a flow-reducing membrane upstream of the valve and designed to limit the height of the flame. The membrane includes a mesoporous layer whose pores have a radius ranging from 20 to 500 ANGSTROM ngstroms and positioned so that an upstream face of this membrane communicates directly with the interior of the liquid fuel reservoir, i.e. without a wicking structure. |
