Abstract
Abstract A single-action ultra-thin cigarette lighter in a card-like format having a taper terminating in a blade-shaped bottom edge making it possible to wedge the lighter between the corresponding faces of the inner and outer wrappers of a standard crushable cigarette pack to serve as a stiffener therefor without significant deformation of the pack. The lighter includes a narrow reservoir for liquefied gas having front and rear walls whose width approaches that of the wrapper faces and whose length is somewhat shorter, the walls being inclined to form the taper. Mounted on top of the reservoir to seal the liquefied gas therein is a similarly narrow lighter assembly that includes a spark generator, a valve having an inlet extending into the reservoir below, and a movable hollow stem which is normally held in a closed position. A push-button operated actuator, when pressed in by the user, raises the stem to open the valve and thereby release gas therefrom, and at the same time actuates the generator to produce a spark which ignites the gas.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
183 words
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.
Claim 2
Dependent Claim
183 words
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.
Claim 3
Dependent Claim
17 words
A lighter as set forth in claim 1, wherein said reservoir is molded of synthetic plastic material.
Claim 4
Dependent Claim
29 words
A lighter as set forth in claim 2, wherein said reservoir includes molded reinforcing ribs joined to said front ad rear walls to resist the pressure of the gas.
Claim 5
Dependent Claim
25 words
A lighter as set forth in claim 1, wherein said spark generator is formed by an abrading wheel whose underside is engaged by a flint.
Claim 6
Dependent Claim
30 words
A lighter as set forth in claim 4, wherein said means is constituted by a push-button operated actuator which when pushed in, simultaneously activates the generator and opens the valve.
Claim 7
Dependent Claim
33 words
A lighter as set forth in claim 1, wherein said spark generator includes a piezoelectric element which when activated by a trigger mechanism produces a high voltage which is applied to spark-gap electrodes.
Claim 8
Dependent Claim
31 words
A lighter as set forth in claim 6 wherein said means is constituted by a push button-operated actuator which when pushed in, simultaneously operates the trigger mechanism and opens the valve.
Claim 9
Dependent Claim
26 words
A lighter as set forth in claim 1 wherein said walls are joined by spaced ribs which act to resist the pressure produced by said gas.
