Abstract
Abstract A gas lighter comprises a cylindrical tank having a filler valve and a burner valve connected to a burner by a conduit. An electrical ignition device is enclosed within a semi-cylindrical holder and a semi-cylindrical, axially displaceable actuating member, the actuating member being provided with means for operating the ignition device and means for opening the burner valve. The tank holder and actuating member are surrounded and held together by a one-part tubular sleeve having an aperture to permit manual movement of the actuating member.
