Single-action ultra-thin cigarette lighter

A cigarette lighter in an ultra-thin card-like format for inse-tion between the corresponding front or rear rectangular faces of the inner and outer wrappers of a standard, crushable cigarette pack without significant distortion thereof, said lighter comprising:

• (A) an open-top narrow reservoir filled with liquefied gas and having a width close to that of said rectangular faces and whose length is somewhat shorter than that of said rectangular faces, said reservoir having front and rear walls which are inclined to create a taper terminating at the bottom edge of the reservoir which is blade-shaped, making it possible to wedge the lighter between said faces;
• and
• (B) a similarly narrow lighter assembly mounted on top of the reservoir to seal the liquefied gas therein, said assembly including a spark generator, a normally closed valve having an inlet extending into the reservoir to admit gas therefrom into a hollow stem having an outlet adjacent the spark generator, and manually-operated means to actuate the generator to produce a spark and to open the valve to emit gas from the outlet to be ignited by the spark.
