Description

A push-pull double-layer cigarette packaging box and its opening and closing method Technical Field

[0001] This invention belongs to the technical field of cigarette packaging boxes, specifically relating to a push-pull double-layer cigarette packaging box and its opening and closing method. Background Technology

[0002] With the continued development of the global economy and the improvement of consumers' living standards, especially the increasing pursuit of personalized and diversified consumption experiences by young consumers, the tobacco industry is facing unprecedented changes and challenges. This trend is particularly evident in the cigarette market, where consumers are no longer satisfied with traditional single-flavor cigarette products, but are more inclined to try new products with novel and unique tastes in order to obtain a richer and more personalized smoking experience.

[0003] To meet this market demand, cigarette companies have increased their R&D investment, striving to enhance their brand competitiveness and achieve brand differentiation strategies through technological innovation and product upgrades. Among these efforts, developing cigarette products with different flavors has become a key focus for companies. This strategy not only requires companies to be bold in their cigarette formulas, incorporating various flavor elements such as fruits, herbs, and spices, but also prompts them to explore more advanced and flexible production processes and packaging technologies to support the realization of diverse flavors.

[0004] In recent years, capsule-shaped flavoring technology has emerged as a major innovation in the cigarette industry. Its ability to release unique aromas and deliver a delightful taste during smoking has quickly gained widespread market recognition and consumer favor. This technology involves embedding capsules containing different flavored essential oils inside the cigarette filter. When the smoker pops the capsule, the essential oils are released, mixing with the tobacco smoke to create a completely new smoking experience. The successful application of this technology has not only enriched the flavor options for cigarettes but also provided new possibilities for innovative cigarette packaging design.

[0005] However, despite significant progress in cigarette flavor innovation and production technology, the current cigarette market still faces considerable innovation gaps in product packaging, particularly in the design and opening mechanisms of boxes for dual- or multi-flavor cigarettes. Traditional cigarette box designs often focus on protecting cigarettes from damage and ease of carrying, while remaining relatively simplistic and homogenous in terms of enhancing user experience and product appeal. Especially with the emerging category of dual-flavor cigarettes, designing a box shape and opening mechanism that effectively distinguishes and displays different flavors while allowing consumers to easily choose their preferred flavor has become a major technical challenge that urgently needs to be addressed.

[0006] To address the above problems, this invention is proposed. Summary of the Invention

[0007] This invention provides a push-pull double-layer cigarette packaging box, comprising:

[0008] The lower outer shell 1, the upper outer shell 2, the inner box 3, the lower inner box 4, and the connecting parts 5.

[0009] The lower outer shell 1 is a cuboid with an opening on the upper wall, located at the bottom of the entire cigarette packaging box, and includes: a first front wall 11, a first rear wall 12, a first left wall 14, a first right wall 13 and a first lower wall 15. The first front wall 11, the first rear wall 12, the first left wall 14, the first right wall 13 and the first lower wall 15 form a hollow bottom cover of the cigarette packaging box.

[0010] The upper outer shell 2 is a cuboid with an opening at the bottom wall, located at the top of the entire cigarette packaging box, and includes: a second front wall 21, a second rear wall 22, a second left wall 24, a second right wall 23, and a second upper wall 25. The second front wall 21, the second rear wall 22, the second left wall 24, the second right wall 23, and the second upper wall 25 form a hollow top cover of the cigarette packaging box.

[0011] The inner box 3 is located inside the entire cigarette packaging box. It is a cuboid with an open upper wall and includes: a third front wall 31, a third rear wall 32, a third left wall 34, a third right wall 33, a third lower wall 36, and a partition 35. The inner box 3 is partially fitted and fixed inside the lower outer shell 1. The partition 35 is located between the third front wall 31 and the third rear wall 32 and is arranged parallel to the third front wall 31 and the third rear wall 32. The third front wall 31, the third left wall 34, the third right wall 33, the third lower wall 36, and the partition 35 form an upper cigarette holder. The third rear wall 32, the third left wall 34, the third right wall 33, the third lower wall 36, and the partition 35 form a lower inner box 4 holder. A hollow area 100 is opened in the lower part of the partition 35.

[0012] The lower inner box 4 is a cuboid with an opening on the upper wall, comprising: a fourth front wall 41, a fourth rear wall 42, a fourth left wall 44, a fourth right wall 43, and a fourth lower wall 45. These four walls form a lower cigarette holder. A U-shaped cutout 200 is provided on the side of the fourth rear wall 42 near the opening on the upper wall of the lower inner box 4, which serves to close and open the lower inner box 4 during the pushing and pulling of the upper outer shell 2. A cutting latch 210 is provided at the bottom of the fourth front wall 41. During the pushing and pulling of the upper outer shell 2, the cutting latch 210 engages on the side above the hollowed-out area 100, positioning the lower inner box 4 during its opening stroke. The cutting area of ​​the cutting latch 210 extends to the junction of the fourth front wall 41 and the fourth lower wall 45; the cutting latch 210 is tightly attached to the lower part of the hollowed-out area 100.

[0013] The connecting component 5 is in the shape of an inverted T. The shoulder width of the inverted T is greater than the width of the U-shaped cutout 200. The shoulder of the inverted T is positioned below the U-shaped cutout 200, and the head of the inverted T is attached to the inner wall of the second rear wall 22.

[0014] Preferably, the upper and lower cigarette storage compartments contain cigarettes of the same or different flavors.

[0015] Preferably, the third left wall 34, the third right wall 33, the fourth left wall 44, and the fourth right wall 43 are trapezoidal in shape.

[0016] Preferably, the height of the third front wall 31 is lower than the height of the partition 35.

[0017] Preferably, the height of the fourth front wall 41 is lower than the height of the fourth rear wall 42.

[0018] Preferably, both the lower outer shell 1 and the upper outer shell 2 are made of rigid cardboard, which has strong paper hardness and thickness, and provides good packaging compression resistance for the inner box and cigarettes.

[0019] Preferably, the thickness of the rigid cardboard is in the range of 0.3mm-1cm.

[0020] The above parts are connected by crease lines.

[0021] In another aspect, the present invention provides a method for opening and closing the cigarette packaging box, the opening method comprising the following steps:

[0022] The user holds the lower outer shell 1 with one hand and presses the upper outer shell 2 with the other hand, pulling it upwards away from the lower outer shell 1. As the upper outer shell 2 is pulled, the cutting buckle 210 is raised at a certain angle and moves from below the hollow area 100 to above until the cutting buckle 210 is locked on the side above the hollow area 100. At this time, the upper cigarette holder and the lower cigarette holder are fully exposed.

[0023] At the same time, the inverted T-shaped shoulder moves upward along the inner wall of the U-shaped cutout 200 until the inverted T-shaped shoulder is stuck at the top of the U-shaped cutout 200, at which point the lower inner box 4 is fully opened.

[0024] The closure method includes the following steps:

[0025] The user holds the lower outer shell 1 with one hand and presses the upper outer shell 2 with the other hand, pushing it downwards along the direction close to the lower outer shell 1. As the upper outer shell 2 is pushed, the inverted T-shaped shoulder moves downwards along the inner wall of the U-shaped cutout 200 until the inverted T-shaped shoulder is stuck below the U-shaped cutout 200. At this time, the lower inner box 4 is completely closed.

[0026] At the same time, the cutting buckle 210 moves from above to below the hollow area 100 until the cutting buckle 210 is tightly attached to the lower side of the hollow area 100, at which point the upper cigarette holder and the lower cigarette holder are completely covered.

[0027] Preferably, the angle at which the cutting buckle 210 is raised is 3-10 degrees.

[0028] The beneficial effects of this invention are:

[0029] 1. The push-pull double-layer cigarette packaging box provided by this invention cleverly divides the internal space of the packaging box into upper and lower layers by designing a partition in the inner box. The upper and lower cigarette storage compartments can store cigarettes of different flavors respectively. This design not only meets consumers' needs for diverse cigarette flavors, but also allows consumers to easily select the desired flavor of cigarettes according to their personal preferences, greatly improving the user experience.

[0030] 2. The push-pull double-layer cigarette packaging box provided by this invention adopts an innovative push-pull opening and closing method. Users can easily open and close the packaging box by simply pulling up or pushing down the outer shell, simplifying the opening process, reducing the complexity of user operation, improving user efficiency, and making the operation process more comfortable and pleasant, further enhancing user satisfaction with the product. The packaging box opens more smoothly and steadily, avoiding problems such as damage or cigarette spillage caused by improper opening methods of traditional cigarette boxes.

[0031] During opening: The user holds the lower outer shell with one hand and pulls the upper outer shell upwards away from the lower outer shell with the other hand. As the upper outer shell is pulled, the cutting latch rises at a certain angle, moving from below the cutout area to above, until the cutting latch is locked on the upper side of the cutout area. At this point, the upper and lower cigarette compartments are fully exposed. Simultaneously, the inverted T-shaped shoulder moves upwards along the inner wall of the U-shaped cut until the inverted T-shaped shoulder is locked at the top of the U-shaped cut, at which point the lower inner box is fully opened.

[0032] During the closing process: The user holds the lower outer shell with one hand and presses the upper outer shell with the other hand, pushing it downwards along the direction close to the lower outer shell. As the upper outer shell is pushed, the inverted T-shaped shoulder moves downwards along the inner wall of the U-shaped cut until the inverted T-shaped shoulder is stuck below the U-shaped cut. At this time, the lower inner box is completely closed.

[0033] At the same time, the cutting clip moves from the top to the bottom of the hollowed-out area until the cutting clip is tightly attached to the bottom side of the hollowed-out area, at which point the upper cigarette storage compartment and the lower cigarette storage compartment are completely covered.

[0034] During the sliding process of the upper outer shell, the U-shaped cutout and the inverted T-shaped structure of the connecting component work together, with the shoulder of the connecting component always locked within the inverted U-shaped cutout, providing a stable guide and limit for the lower inner box. Simultaneously, the cutting latch located at the bottom of the front wall of the lower inner box also plays a crucial role. This cutting latch rises at a certain angle during the pulling of the upper outer shell, moving from below the cutout area to above until it locks securely on the upper side of the cutout area, thus limiting movement and ensuring that the lower inner box does not move excessively or slip when pulled upwards. When the lower inner box is pulled to its foremost position, the cutting latch locks securely on the upper side of the cutout area, achieving stable fixation.

[0035] 3. The push-pull double-layer cigarette packaging box provided by this invention emphasizes the integration of personalized elements in its appearance design. For example, the trapezoidal wall design not only enhances the three-dimensionality of the packaging box but also makes it more in line with modern aesthetic trends. At the same time, the push-pull opening and closing mechanism brings consumers a brand-new user experience, increasing the product's fun and interactivity, thereby enhancing the product's market competitiveness and brand image.

[0036] 4. The push-pull double-layer cigarette packaging box provided by the present invention has both the lower and upper outer shells made of rigid cardboard, which has strong paper hardness and thickness, and has good packaging pressure resistance for the inner box and cigarettes. The sturdy hard box outer shell design can better protect the cigarettes and prevent them from getting damp or damaged.

[0037] 5. The cigarette packaging box of this invention has a simple design, strong practicality, and is very suitable for industrial production. Attached Figure Description
