Description

Technical Field

[0001] This invention belongs to the field of tobacco packaging technology, and specifically relates to a slotted cigarette packaging box. Background Technology

[0002] As consumers increasingly demand personalized cigarette packaging, the top-and-bottom box, a type of handmade cigarette pack with sharp edges and a sturdy appearance, is favored by many consumers among mid-to-high-end cigarette pack types. However, because top-and-bottom boxes require manual forming and processing, production costs are high, the manufacturing cycle is long, and the printing process is not fully mechanized. Furthermore, the filling process must also incorporate automated cigarette-filling equipment, increasing the complexity of the process.

[0003] However, the commonly used mechanized small cigarette boxes are packaged using an embossing process. After the packaging is formed, the embossed corners are relatively rounded, lacking the sharp corners and full, high-end feel of handmade boxes with top and bottom lids.

[0004] There is an existing carton slotting technology, but the carton slotting process only requires ensuring that the slot lines are accurate, straight, and stable in a straight line to achieve the three-dimensional structure and clear, sharp-edged effect of the carton. However, the positioning and slotting process for small boxes is more difficult because the box shape of small boxes is more complex, with more slot lines, requiring staggered and positioned slotting. Otherwise, the thickness of the paper itself will affect the bending and deformation of the outer paper surface during folding, resulting in an uneven appearance of the cigarette pack and affecting its aesthetics. Because the small box slotting process is less used in the tobacco packaging technology field, currently, the selection of paper substrates can only be determined by testing the flatness and angles of each surface of the box after actual slotting to see if the paper substrate is suitable for slotting. This experimental efficiency is low, leading to a longer product development cycle. Summary of the Invention

[0093] (2) Use a cutting device to cut the paper substrate or slotted paper substrate into test samples;

[0094] (3) Install the test sample on the stiffness fixture and start the stiffness tester to obtain the crease stiffness of the test sample.

[0095] In step S3, the grooving depth is 0.10mm–0.20mm, 0.20mm–0.30mm, 0.30mm–0.50mm, or 0.50–1.00mm. The grooving width is 0.10mm–0.50mm, 0.50mm–1.50mm, 1.50mm–3.50mm, or 3.50–4.00mm. The groove line is set along the crease of the grooving line; the crease of the grooving line is set on the grooving paper substrate to form the edge of the grooved cigarette packaging box.

[0096] refer to Figure 1In some embodiments, a typical slotted cigarette packaging box includes a box section 1 and a flip-top lid 2; the box section 1 includes a front wall 11, a bottom wall 12, and a rear wall 13 connected in sequence; the front wall has first box side walls 14 on two opposite sides, and the rear wall has second box side walls 15 on two opposite sides; during the molding of the box section, the first box side walls are bonded to the second box side walls, or the second box side walls are bonded to the first box side walls; the flip-top lid 2 includes a lid rear wall 21, a lid top wall 22, a lid front wall 23, and a lid inner sheet 24 connected in sequence; the lid rear wall has first lid side walls 25 on two opposite sides, and the lid front wall has first lid side walls 25 on two opposite sides, and the lid rear ... Each side has a second cover sidewall 26; during the forming of the flip-top lid, the first cover sidewall is bonded to the second cover sidewall, or vice versa; the first box sidewall is folded to the front wall, with the crease being an indentation line crease; the second box sidewall is folded to the rear wall, with the crease being an indentation line crease 7; the front wall, bottom wall, and rear wall are all folded to form creases, with the creases being slotted lines crease 6; the first cover sidewall is folded to the rear wall, with the crease being an indentation line crease; the second cover sidewall is folded to the front wall, with the crease being an indentation line crease; the rear wall, top wall, and front wall are all folded to form creases, with the creases being slotted lines crease. Compared to indentation lines, slotted lines have spaced notches, making them less prone to wrinkles and bulges during folding and easier to fold. Two opposite sides of the bottom wall are provided with first bottom corner pieces 16. The first bottom corner pieces are connected to one of the first box side walls and the second box side walls. One side of the first bottom corner piece is folded and connected to one of the first box side walls and the second box side walls by an indentation line or a slotting line. The remaining periphery of the first bottom corner piece is a cutting line. Two opposite sides of the top wall are provided with second bottom corner pieces 27. The second bottom corner pieces are connected to one of the first lid side walls and the second lid side walls. One side of the second bottom corner piece is folded and connected to one of the first lid side walls and the second lid side walls by an indentation line or a slotting line. The remaining periphery of the second bottom corner piece is a cutting line 8. One of the first box side walls and the second box side walls is provided with an adhesive dispensing area 5. The adhesive dispensing area is distributed with adhesive penetration points. The adhesive penetration point structure facilitates the penetration of adhesive, thereby making the two more firmly bonded. Preferably, the adhesive dispensing area occupies 2 / 3-4 / 5 of the entire side wall area. One of the first and second cover sidewalls has an adhesive application area with adhesive dots distributed within it. The top and rear walls of the cover have staggered lines (4) on their sides, with the lines offset from each other. The cut line (8) on the top wall and the indentation line (7) on the rear wall are also staggered. Preferably, the difference in the staggered lines is designed based on the thickness of the cardboard; for example, if the cardboard thickness is 0.5mm, the difference in line position is designed to be 0.5mm. The advantage of this staggered line design is that when the box is rolled and formed, the front dimension is larger than the back dimension, with a 0.5mm margin on each side, allowing the larger front to wrap the smaller back. A slit (3) is provided between the second box sidewall and the first cover sidewall, facilitating folding and connection.

[0097] The first box has its side wall folded and connected to the front wall, with the crease forming the first edge of the slotted cigarette packaging box; the second box has its side wall folded and connected to the rear wall, with the crease forming the second edge of the slotted cigarette packaging box; the front wall, bottom wall, and rear wall are all folded and connected, with the crease forming the third edge of the slotted cigarette packaging box; the first lid's side wall is folded and connected to the lid's rear wall, with the crease forming the fourth edge of the slotted cigarette packaging box; the second lid's side wall is folded and connected to the lid's front wall, with the crease forming the fifth edge of the slotted cigarette packaging box; and the lid's rear wall, top wall, and front wall are all folded and connected, with the crease forming the sixth edge of the slotted cigarette packaging box.

[0098] In step S5, if the stiffness difference is less than zero, it is determined that the slotted paper substrate is not suitable for forming a slotted cigarette packaging box. In step S5, the larger the stiffness difference, the more suitable the slotted paper substrate is for forming a slotted cigarette packaging box.

[0099] At least one of the edges of a slotted cigarette pack can be formed by creases, for example, see [example missing]. Figure 1 The second cover sidewall is bonded to the first cover sidewall; the first box sidewall is folded to the front wall, with the crease being the crease line 7; the second box sidewall is folded to the rear wall, with the crease being the crease line 7; the front wall, bottom wall, and rear wall are all folded together, with the crease being the slotted line 6; the first cover sidewall is folded to the rear wall, with the crease being the crease line 7; the second cover sidewall is folded to the front wall, with the crease being the crease line 7; the rear wall, top wall, and front wall are all folded together, with the crease being the slotted line 6. Compared to crease lines, slotted lines have spaced notches, making them less prone to wrinkles and bulges during folding and easier to fold.

[0100] The substrate for slotted paper is white cardboard, transfer paper, or composite paper.

[0101] Hard-pack cigarette packaging boxes are designed to hold 20 cigarettes.

[0102] Example

[0103] The present invention will be further described below with reference to specific embodiments. In each embodiment, the paper substrate used is a commercially available product, and its manufacturing process basically includes:

[0104] Platinum embossed composite paper: paper and film lamination → back coating → drying → varnishing → drying → winding → slitting → packaging.

[0105] Transfer silver column paper: paper and film lamination → back coating → drying → peeling → varnishing → drying → winding → slitting → packaging.

[0106] Aluminum foil composite paper: Aluminum foil lamination → PET lamination → Embossing → Slicing into sheets.

[0107] Before slotting, the parameters of the paper substrate are as follows:

[0108] Table 1. Slot width and depth of paper substrate

[0109]

[0110] Referring to the grooving methods in Chinese patents 202410229748.2 and 202310843510.4, grooving is performed on the paper substrate, with the groove lines referring to... Figure 2 The first groove line 10, the second groove line 20, the third groove line 30, the fourth groove line 40, the fifth groove line 50 and the sixth groove line 60.

[0111] The slot width and depth are shown in Table 2.

[0112] Table 2. Slot width and depth

[0113]

[0114] After slotting, testing Figure 1 The stiffness of each groove is shown in Table 3. In other embodiments, the grooves may also be formed in other substrates used to form the corners of the rigid box.

[0115] Table 3. Groove line stiffness after grooving

[0116]

[0117] Appearance evaluation

[0118] Fold each paper substrate into a GDX rigid box to obtain three of each: platinum embossed composite paper box 1000, transfer silver cylindrical paper 2000, aluminum foil composite paper (gold) 3000, and aluminum foil composite paper (silver) 4000. (Reference) Figures 3-5 The angles of each corner and the flatness of each surface on the box were measured, and the data were compiled into Tables 4, 5, 6, and 7. The largest side of the hard box with opening line 101 is the front 100. Figure 4 The spatial relationships shown are as follows: the other surfaces are, in order, the back surface 200, the top surface 300, the bottom surface 400, the left side surface 500, and the right side surface 600.

[0126]

[0127]

[0128] Table 7. Aluminum Foil Composite Paper (Silver)

[0129]

[0130]

[0131]

[0132] It can be seen that, in terms of angular sharpness and stability, platinum embossed composite paper is superior to transferred silver column paper, which is superior to aluminum foil composite paper (gold), which is superior to aluminum foil composite paper (silver). When the angle data are close to 90 degrees, the rigid box packaging has sharp edges and a highly impactful visual effect.

[0133] In addition, in terms of flatness and edge length stability, platinum embossed composite paper is superior to transferred silver luminous paper, which is superior to aluminum foil composite paper (gold), which is superior to aluminum foil composite paper (silver). The smaller the flatness, the more stable the edge length, which also means that the rigid box packaging box has sharp edges. At the same time, it also shows that the substrate has good adaptability to the grooving process, and still has good flatness and stability after grooving and boxing.

[0134] Furthermore, paper substrates with an average stiffness of more than the original stiffness of the paper substrate before slotting are more suitable for slotting, resulting in rigid packaging boxes with a superior appearance. Moreover, the greater the stiffness difference, the more suitable the paper substrate is for slotting, and the better the appearance of the resulting rigid packaging box.

[0135] Similarly, it should be noted that although the present invention has been described with reference to the specific embodiments described above, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and various equivalent changes or substitutions can be made without departing from the spirit of the present invention.
