Description

Technical Field

[0001] This utility model belongs to the field of tobacco product packaging technology, specifically relating to a dual-compartment moisture-retaining cigarette packaging box that controls the flavor of two different flavored cigarettes and preserves their freshness and moisture. Background Technology

[0002] With the development and innovation of cigarette categories, packaging formats containing two or more flavors per pack have become a new consumer trend and technological reserve, capable of meeting consumers' diverse daily taste needs. Currently, many traditional preservation and moisture-control packaging materials exist on the market, but they suffer from the following problems: 1. They typically use single-compartment packaging; only one flavor of cigarette is available, making it impossible to achieve packaging of two or more flavors per pack and control over aroma. 2. Packaging materials are usually flat sheets, resulting in relatively low production efficiency. 3. Existing technology uses single-layer materials, leading to insufficient packaging structural strength and unstable heat-sealing performance, affecting the overall product quality. Therefore, there is an urgent need for a novel, precisely engineered, dual-compartment or multi-compartment flavor-control packaging box suitable for high-speed automated production, along with its preparation method.

[0003] This utility model is proposed for this purpose. Utility Model Content

[0037] like Figure 1 As shown, this utility model discloses a double-compartment moisture-retaining cigarette packaging box, which contains two inner boxes, each inner box including a frame paper 1 as shown. Figure 2 As shown, the inner lining paper 2 wrapped around the frame paper 1 is as follows: Figure 5 As shown, and the self-adhesive seal 3 is pasted on the upper center opening of the inner box. Figure 7 As shown.

[0038] The two inner boxes are cubic in shape and the same size; the frame paper 1 is rectangular in shape, with a U-shaped opening 12 at the top center and a U-shaped tongue 17 at the bottom center, the U-shaped tongue 17 being exactly the same size as the U-shaped opening 12. Figure 2 As shown; there is a vertical crease line 13 on each side of the frame paper 1 at a certain distance from the edge; there is a fold line 18 between the U-shaped tongue 17 and the frame paper 1; the left and right side walls of the frame paper 1 are folded inward along the crease line 13, and the U-shaped tongue 17 is folded inward along the fold line 18 to form the front end face 14, the left end face 15, the right end face 16, and the bottom end face; the frame paper 1 serves as the supporting structure of the inner box to ensure the strength of the inner box, therefore, the frame paper 1 has certain requirements for hardness; the inner lining paper 2 wraps around the folded frame paper 1 to form a sealed hexagonal inner box; the upper center of the front of each inner box has an opening in the inner lining paper 2, which is a U-shaped cut 22; the U-shaped cut 22 extends upward to the upper end face of the inner box; the U-shaped cut 22 corresponds to the U-shaped opening 12 of the frame paper 1, as shown. Figure 5As shown, this is used for taking out cigarettes; the self-adhesive seal 3 is pasted around the U-shaped cut 22 and extends to the top and rear surfaces of the inner box; the self-adhesive seal 3 is rectangular, and its front side includes: a folded rear surface 31, a folded top surface 32, a folded front surface 33, and a front opening area 34. The folded rear surface 31 has three positioning marks 35 for detection and positioning; the back of the self-adhesive seal 3 includes an adhesive area 36 and a non-adhesive area 37. The adhesive area 36 corresponds to the folded rear surface 31, folded top surface 32, and folded front surface 33 on the front side, and the non-adhesive area 37 corresponds to the front opening area 34, as shown. Figure 7 As shown.

[0039] The U-shaped tongue 17 or U-shaped opening 12 has a width of 24mm and a height of 12mm; the U-shaped cut 22 has a width of 20mm and a height of 21mm; the folded frame paper 1 has a height of 88mm, a width of 30mm, and a thickness of 11mm; the self-adhesive seal 3 has a length of 50mm and a width of 28mm, the height of the non-adhesive area 37 is 10mm, and the height of the folded front end face 33 is 16mm; the self-adhesive seal 3 is a functional seal that can be repeatedly opened and sealed to ensure odor control and freshness of the compartment and prevent cross-contamination of odors between the two compartments.

[0040] The inner liner 2 has a three-layer composite structure: the middle layer is an aluminized PET (VMPET) film layer, and the inner and outer layers are biaxially oriented polypropylene (BOPP) film layers. Using this type of liner ensures that the outer layer can be heat-pressed to form a sealed inner box while maintaining its moisture-retaining properties. This is because the aluminized PET (VMPET) film layer has excellent moisture and oxygen barrier properties, ensuring long-term stable humidity inside the inner box and preventing odor transfer. Therefore, the three-layer composite structure ensures excellent heat-sealing performance and moisture-retaining barrier properties.
