Abstract

A combined lighter and pen includes a pen part and a lighter part detachably combined with each other. The pen part has an internally threaded top section. The lighter part includes a gas container provided at its upper end with an ignition device as well as a gas nozzle, and at its lower end with an externally threaded engagement section detachably engageable with the threaded top section of the pen part. The gas container is slidably received by a hollow outer casing which engages with an internally threaded upper cap. The upper cap is provided with a removable metal net which is heated by a flame projected from the gas nozzle. The lighter is operated by an operating piece movably received by a side opening of the outer casing such that its pressing part rests on a side section of the nozzle control piece and comes into close contact with a top end of the ignition switch of the ignition device. When pressed down, the operating piece presses down the nozzle control piece as well as the ignition switch. The operating piece is supported by a clip such that it is positioned in a place in the side opening of the outer casing.
