Abstract
Abstract A cigarette lighter has a cylindrical fuel-containing housing provided at its head with a burner, a valve having a lever operable to feed fuel from the housing interior to the burner, and a striker wheel for sparking across the burner and igniting fuel issuing therefrom. A shield surrounds the projecting end of the valve lever and prevents its actuation. This shield is releasably connected to the housing by a plurality of frangible webs to allow its removal after purchase of the lighter. These webs are integrally formed with the shield and with the synthetic-resin reservoir body of the housing or with the metallic head cap thereof.
