Flat cigarette lighter

Claim 1

In combination with a standard soft cigarette pack wherein cigarettes are housed within an inner wrapper to form a crushable body which is enveloped and sealed within an outer wrapper having a rectangular face, said inner wrapper having a corresponding face which is spaced from the outer wrapper face by the insertion therebetween of a flat, ultra-thin cigarette lighter when the top portion of the outer wrapper is removed to provide access to the cigarettes, whereby the inserted lighter then functions as a stiffener to resist crushing of the pack without substantially altering the overall dimensions thereof, said lighter comprising: A a shallow generally rectangular container having a card format molded of synthetic plastic material to provide a reservoir which is filled with a liquefied gas that subjects the container to high internal pressure, said container having front and rear walls defined by parallel plates which are joined together by ribs to resist the pressure produced by the liquefied gas, said container having a width approaching the width of said wrapper faces, a length that is somewhat shorter than that of the wrapper faces and a thinness which allows insertion of the container in the space between said wrapper faces without distortion of the pack; and B a lighter assembly mounted on the upper portion of the container and having substantially the same thinness, said assembly including a normally-closed valve whose inlet is coupled to the reservoir, a nozzle communicating with the valve to emit said gas when the valve is opened, a spark generator adjacent said nozzle, said generator, when actuated, producing sparks, and a manually-operated actuator operatively coupled to said valve, whereby when the actuator is operated it acts to open said valve to cause gas to be emitted from said nozzle to be ignited by sparks from the generator.
