[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of the pressure-resistant cigarette box of this utility model, please refer to... Figs. 1 to 4 A pressure-resistant cigarette box includes a cover 100, a cushioning layer 200, a support frame 400, and a box body 300. The inner sidewalls of the box body 300 are provided with mounting grooves 310. The outer sidewalls of the support frame 400 are provided with mounting parts 410 that cooperate with the mounting grooves 310. The inner sidewall of the cover 100 is provided with a slot 110. The locking blocks 210 on the outer periphery of the cushioning layer 200 connect to the slot 110 to position the cushioning layer 200 inside the cover 100.

[0028] Specifically, because the inner wall of the box 300 has a mounting groove 310, the support frame 400 is installed around the box 300 through the connection between the mounting part 410 and the mounting groove 310, effectively supporting the side wall of the box 300 and preventing the carton from deforming due to external pressure during transportation or storage; at the same time, it increases the overall structural strength and load-bearing capacity of the carton, making it more stable during transportation, handling and stacking, reducing the possibility of deformation due to weight when the carton is stacked, thereby protecting the cigarette box inside the carton. Because the buffer layer 200 is positioned inside the cover 100 by engaging with the slot 110 through the latch 210, the buffer layer 200 can absorb impact and vibration, and through elastic deformation, it keeps the cigarette box tightly against the support frame 400 inside the box 300, preventing the cigarette box from being squeezed and deformed or worn by shaking, and preventing the cover 100 from being deformed by pressure. The separate design of the cover 100 and the box 300 supports quick opening and closing, allowing the same cover 100 to match various heights of the box 300, reducing costs. In addition, the detachable installation of the support frame 400 and the buffer layer 200 allows for quick and easy replacement in case of partial damage, reducing maintenance costs.

[0029] Furthermore, the slot 110 of the cover has a T-shaped structure, and the shape of the locking block 210 matches the slot 110. The bottom cross-sectional area of ​​the slot 110 is smaller than the top cross-sectional area. Specifically, the T-shaped slot 110 and the locking block 120 are locked together without the need for additional adhesive, thus avoiding the problem of the buffer layer 200 loosening or detaching due to vibration during transportation, which is common with traditional adhesive methods. In addition, because the bottom cross-sectional area of ​​the slot 110 is smaller than the top cross-sectional area, the buffer layer 200 is less likely to detach from the cover 100 after being inserted into the slot 110.

[0030] Furthermore, the buffer layer 200 has a density of 80–120 kg / m³. 3 The EVA foam material has evenly distributed ventilation holes on its surface, and the bottom of the cushioning layer 200 is attached to the top surface of the support frame 400. Specifically, the foam is lightweight, and the high-density foam has good support performance, effectively relieving vibration and stacking pressure during transportation, and preventing carton deformation and cigarette breakage. Because the foam has evenly distributed micro-ventilation holes, it helps keep the inside of the carton dry; and the bottom of the cushioning layer 200, attached to the top surface of the support frame 400, maintains the airtightness of the box body 300.

[0031] Furthermore, the mounting groove 310 of the box has a trapezoidal or dovetail-shaped cross-section, and the mounting part 410 of the support frame is adapted to the shape of the mounting groove 310. Specifically, the inclined surface of the trapezoidal or dovetail-shaped mounting groove 310 fits tightly with the mounting part 410, increasing the contact area, reducing the risk of the support frame loosening, and enhancing the structural strength and deformation resistance of the box 300. Preferably, the support frame 400 consists of four separate side panels, each side panel having a mounting part 410 adapted to the mounting groove 310 on one side. Specifically, before assembly, the side panels can be stacked and stored without occupying too much space; when assembling the carton, the side panels are then installed one by one on the inner side wall of the box 300.

[0032] Furthermore, the support frame 400 is made of high-density corrugated cardboard, and the interior of the corrugated cardboard has multiple parallel vertical support columns 420. Specifically, the multiple support columns 420 enhance the longitudinal load-bearing capacity of the box, making it suitable for multi-layer stacking of cartons.

[0033] Furthermore, the support frame 400 is injection molded from ABS plastic. Specifically, the plastic support frame with a certain degree of rigidity enhances the load-bearing capacity of the box 300, maintaining its supporting strength even in humid environments. The plastic material also facilitates disassembly and cleaning, keeping the box clean. Preferably, the inner wall of the support frame 400 is integrally molded with a snap-fit ​​structure for assembling and fixing partitions. Specifically, partitions can be assembled on the inner side of the support frame 400, dividing the inner cavity of the box 300 into multiple cavities. The partitions further enhance the carton's resistance to deformation and prevent concentrated local stress.

[0034] Furthermore, the bottom of the box 300 is provided with a reinforcing layer 320, which is a composite structure of double-layer corrugated cardboard sandwiched with a plastic sheet. Specifically, the reinforcing layer improves the compressive strength of the bottom of the box 300, and the plastic sheet sandwiched in the middle can effectively block external moisture penetration.

[0035] Furthermore, the four corners of the enclosure 300 are covered with protective corner protectors 330, which are made of rubber or silicone. Specifically, the rubber or silicone protective corner protectors 330 protect the four outer corners of the enclosure 300 from impact. The protective corner protectors 330 can be attached to the enclosure 300 with double-sided tape or hot melt adhesive.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
