Claim 4:
5. 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;
3) Filling an interior of the special-shaped cigarette accommodating cavity with an ordinary cigarette; and
4) 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 triangular cigarette with a cross section being a triangle;
wherein the packaging case paper comprises a triangular-cigarette first inner cavity partition board and a triangular-cigarette second inner cavity partition board;
the triangular-cigarette first inner cavity partition board is provided with a plurality of parallel crease lines in advance, and is folded along the crease lines into a triangular-cigarette first triangular protrusion and a triangular-cigarette first triangular groove that are sequentially connected and have a cross section being a triangle, and the triangular-cigarette first triangular protrusion and the triangular-cigarette first triangular groove have the same size and shape;
the triangular-cigarette second inner cavity partition board is provided with a plurality of parallel crease lines in advance, and is folded along the crease lines into a triangular-cigarette second triangular protrusion and a triangular-cigarette second triangular groove that are sequentially connected and have a cross section being a triangle, the triangular-cigarette second triangular protrusion and the triangular-cigarette second triangular groovehave the same size and shape, and the triangular-cigarette second triangular groove internally has a vertical triangular-cigarette spacer;
the folded triangular-cigarette first inner cavity partition board and triangular-cigarette second inner cavity partition board are stacked in an obverse-reverse opposite mode, the triangular-cigarette first triangular protrusion of the triangular-cigarette first inner cavity partition board on the upper layer is opposite to the triangular-cigarette second triangular groove of the triangular-cigarette second inner cavity partition board on the lower layer to be capable of forming a plurality of sequentially connected cigarette accommodating cavities with the cross section being a rhombus, and the vertical triangular-cigarette spacer in the triangular-cigarette second triangular groove is respectively connected to a triangular vertex of the triangular-cigarette first triangular protrusion on the upper layer and a triangular vertex of the triangular-cigarette second triangular groove on the lower layer, so as to divide the rhombic cigarette accommodating cavities into middle-layer triangular accommodating cavities on two sides of the vertical triangular-cigarette spacer; and
the triangular-cigarette first triangular groove is an upper-layer triangular accommodating cavity, and the triangular-cigarette second triangular protrusion is a lower-layer triangular accommodating cavity; and the upper-layer triangular accommodating cavity, the middle-layer triangular accommodating cavities and the lower-layer triangular accommodating cavity have fixing and extruding effects on the cigarettes, so that cross sections of circular cigarettes become triangles and the circular cigarettes are accommodated in the accommodating cavities.
