Abstract
Abstract A cigarette lighter has a cylindrical fuel-containing reservoir provided on one end with a burner, a valve having a lever operable to feed fuel from the reservoir to the burner, and a striker wheel for sparking across the burner and igniting the fuel. A metal cap covers this end and has a cutout receiving the wheel and in the line with the burner. A metal tab blocks that portion of the cutout aligned with the burner and is connected to the rest of the cap by a plurality of destructible webs. This tab has a tongue extending up over the striker wheel and out above the lever so that the striker wheel cannot be actuated, nor can the lever, and the burner is covered. This protective arrangement is removable after sale to expose the lever, striker wheel, and burner and allow use of the lighter.
