Abstract
An improved cigarette and method of manufacture utilizes a specialized paper incorporating a narrow air tube portion along one of its longitudinal edges, and an elongated, generally rod-shaped rolling bar inserted into and through the air tube, used to roll up and capture tobacco spread over the paper's surface. The specialized cigarette paper incorporates a strip of small filter "flaps" into the construction of the air tube. The resultant cigarette emplaces the tobacco within a single, continuously spiraling envelope of cigarette paper about the central, longitudinal air-tube axis, with the filter flaps extending radially inward to filter the cigarette smoke.
Claims8
An improved cigarette comprising:
- an elongated paper cylinder having an outside surface and an inside surface, and an interior volume, said interior volume having a longitudinal axis;
- a generally hollow central air tube portion having an inside surface and an outside surface, said air tube extending along said interior volume longitudinal axis and including a plurality of filter flap members extending generally radially inward from said air tube inside surface;
- and
- a paper layer defining a diminishing-radius spiral extending from said paper cylinder inside surface to said central air tube outside surface, wherein a smoking substance is captured adjacent said paper layer and between said paper cylinder inside surface and said central air tube outside surface.
An improved cigarette paper comprising:
- a generally rectangular sheet having a top surface and a first and second longitudinal edge;
- a first adhesive strip applied adjacent said first longitudinal edge;
- a second adhesive strip applied adjacent said second longitudinal edge;
- and
- a plurality of filter flaps incorporated into said paper adjacent said first adhesive strip, so that said first longitudinal edge can be folded over onto said sheet top surface to form a tube, and said filter flaps are captured within said tube.
