Abstract
A gas-fueled cigarette lighter having front and rear walls defined by plates which are joined together by a plurality of ribs to resist pressure produced by the gas, wherein the lighter has a flat ultra-thin format which lends itself to insertion between the inner and outer wrappers of a standard cigarette pack so that the smoker is never at a loss for a light and the inserted lighter functions as a stiffener to prevent crushing of the pack. The lighter is constituted by a card-like body having a shallow reservoir therein filled with liquified gas. Fitting into a corner cut-out in the body is a lighter assembly whose thickness is not greater than that of the body. The assembly includes a valve-controlled nozzle coupled to the reservoir and an adjacent thumb wheel against which a flint is pressed such that when the wheel is turned it abrades the flint to generate sparks that ignite vapor emitted from the nozzle.
