Abstract
Abstract A burner for a gas fuel cigarette lighter is disclosed which provides a distributor to produce a plurality of gas jets, and an outer shield arranged so that a circular flame is produced which is windproof. This burner structure prevents deposition of carbon around the valve stem, due to incomplete combustion of the fuel, and avoids cleaning and repair.
