Claim 6:
7. A method for manufacturing and packaging a special-shaped cigarette, comprising the following steps:
1) Designing inner packaging case paper capable of being folded into a special-shaped cigarette accommodating cavity;
2) Folding the inner packaging case paper to form the special-shaped cigarette accommodating cavity;
1) Filling an interior of the special-shaped cigarette accommodating cavity with an ordinary cigarette; and
2) Shelving for a certain period of time, so that a cross section of the ordinary cigarette changes from a circle to a special shape under fixing and extruding effects of the special-shaped cigarette accommodating cavity and the ordinary cigarette is accommodated in the special-shaped cigarette accommodating cavity, wherein
a diameter of an inscribed circle of the special-shaped cigarette accommodating cavity is less than a diameter of the ordinary cigarette, and a material of the inner packaging case paper is a paperboard or a food grade polyvinyl chloride sheet;
the special-shaped cigarette is a hexagonal cigarette with a cross section being a hexagon;
wherein the packaging case paper comprises at least two layers of hexagonal-cigarette inner cavity partition boards, the hexagonal-cigarette inner cavity partition boards are provided with hexagonal-cigarette crease lines in advance, and are folded along the crease lines into a hexagonal-cigarette trapezoidal protrusion and a hexagonal-cigarette trapezoidal groove that are sequentially connected and have a cross section being a trapezoid, the hexagonal-cigarette trapezoidal protrusion and the hexagonal-cigarette trapezoidal groove have the same size and shape, the folded two layers of hexagonal-cigarette inner cavity partition boards are stacked in an obverse-reverse opposite mode, the hexagonal-cigarette trapezoidal protrusion of the hexagonal-cigarette inner cavity partition board on an upper layer is opposite to the hexagonal-cigarette trapezoidal groove of the hexagonal-cigarette inner cavity partition board on a lower layer to be capable of forming a plurality of sequentially connected cigarette accommodating cavities with cross sections being hexagons, and the cigarette accommodating cavities generate fixing and extruding effects on cigarettes to cause cross sections of the cigarettes to become hexagons and the cigarettes be accommodated in the cigarette accommodating cavities.
