Claim 2:
3. 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 square-circle combined cigarette with a cross section at one end being a circle and a cross section at the other end being a square;
wherein inner packaging case paper of the square-circle combined cigarette comprises a square-circular-cigarette filling and compressing positioning sleeve, a square-circular-cigarette inner cavity fixing sleeve, a square-circular-cigarette middle layer fixing sleeve, and a square-circular-cigarette partition board;
the square-circular-cigarette filling and compressing positioning sleeve is the same as the square-cigarette filling and compressing positioning sleeve in claim 1;
the square-circular-cigarette inner cavity fixing sleeve comprises a square-circular-cigarette first side plate, left and right sides of the square-circular-cigarette first side plate are respectively connected with square-circular-cigarette second side plates, one end of each square-circular-cigarette second side plate far away from the square-circular-cigarette first side plate is connected with a square-circular-cigarette third side plate, and upper and lower edges of the square-circular-cigarette third side plate have square-circular-cigarette side wings;
the square-circular-cigarette second side plate and the square-circular-cigarette third side plate are folded towards a side of the square-circular-cigarette first side plate, and the square-circular-cigarette side wings are folded towards a side of the square-circular-cigarette second side plate to form a square-circular-cigarette trapezoidal groove, the square-circular-cigarette first side plate is a plane where an upper bottom of the square-circular-cigarette trapezoidal groove is located, the square-circular-cigarette third side plate is a plane where a waist of the square-circular-cigarette trapezoidal groove is located, and the square-circular-cigarette second side plate is perpendicular to the square-circular-cigarette first side plate and is located on an outer side of the square-circular-cigarette third side plate; and the square-circular-cigarette second side plate, the square-circular-cigarette third side plate and the square-circular-cigarette side wings are folded to form a square-circular-cigarette triangular prism, and a bottom surface of the square-circular-cigarette triangular prism is located on the square-circular-cigarette first side plate, so as to define the plane where the upper bottom of the square-circular-cigarette trapezoidal groove is located;
the square-circular-cigarette middle layer fixing sleeve comprises two square-circular-cigarette fourth side plates, two square-circular-cigarette fifth side plates, two square-circular-cigarette sixth side plates, and one square-circular-cigarette seventh side plate;
the square-circular-cigarette sixth side plates and the square-circular-cigarette fifth side plate are located on two sides of the square-circular-cigarette fourth side plate, and the square-circular-cigarette seventh side plate is located between the two square-circular-cigarette sixth side plates; and the square-circular-cigarette fifth side plates and the square-circular-cigarette sixth side plates are consistent in size and shape;
the square-circular-cigarette seventh side plate is a first isosceles trapezoid, one side close to the square-circular-cigarette fourth side plates is a bottom of the first isosceles trapezoid, the square-circular-cigarette seventh side plate has a second isosceles trapezoid crease line, similarly, one side close to the square-circular-cigarette fourth side plates is a bottom of the second isosceles trapezoid crease line, the square-circular-cigarette seventh side plates is capable of being folded to form a square-circular-cigarette trapezoidal protrusion by folding along the second isosceles trapezoid crease line, and a trapezoidal notch corresponding to the square-circular-cigarette seventh side plate is formed between the two square-circular-cigarette fifth side plates;
the square-circular-cigarette fifth side plates are folded towards a direction of the square-circular-cigarette sixth side plates through the square-circular-cigarette fourth side plates, the square-circular-cigarette fifth side plates are relatively parallel to the square-circular-cigarette sixth side plates to be capable of forming two right-angle grooves, and the square-circular-cigarette trapezoidal protrusion is located between the two right-angle grooves;
the right-angle grooves are inserted in the square-circular-cigarette trapezoidal groove, the square-circular-cigarette filling and compressing positioning sleeve is folded into a first cuboid, the square-circular-cigarette trapezoidal groove is wrapped with the first cuboid to form an upper layer, a middle layer and a lower layer, and the right-angle grooves are the middle layer;
the square-circular-cigarette partition board comprises a square-circular-cigarette plate main body and a plurality of square-circular-cigarette vertical spacers perpendicular to the square-circular-cigarette plate main body and erected on the square-circular-cigarette plate main body, each square-circular-cigarette vertical spacer is inserted into a gap between the adjacent cigarettes so as to generate fixing and extruding effects on cigarettes on two sides of the square-circular-cigarette vertical spacer; and
circular cigarettes in the square-circular-cigarette trapezoidal groove are changed into cigarettes with one ends being square and the other ends being circular under four kinds of fixing and extruding of the square-circular-cigarette filling and compressing positioning sleeve, the square-circular-cigarette inner cavity fixing sleeve, the square-circular-cigarette middle layer fixing sleeve, and the square-circular-cigarette partition board.
