For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0027] In one embodiment of the present application, as Figures 1-5As shown, a crush-resistant folding carton for cigarettes is provided, including a cuboid carton body 100, each adjacent face of the carton body 100 is provided with a triangular corner protector 110, a pair of opposite panels in the horizontal direction of the carton body 100 are provided as a plate A 130 and a plate B 140, the middle end of the plate A 130 and the plate B 140 is provided with a vertical downward fold 150, so that the plate A 130 and the plate B 140 are folded in half along the fold 150. Another pair of opposite panels in the horizontal direction of the carton body 100 are provided as a plate C 160 and a plate D 170, the plate C 160 and the plate D 170 are sequentially provided with a wear-resistant layer 300, a moisture-proof layer 310, a hardening layer 320 and a corrugated layer 340 from outside to inside, and the hardening layer 320 includes a ring 321 at the middle end and a guide strip 322 extending from the ring 321 to the four corners of the same face.

[0028] Specifically, the initial carton is in a folded state when it is not unfolded, at this time the plate A 130 and the plate B 140 are folded in opposite directions and along the fold 150 to form a small-volume carton folding state. When packaging is needed, the carton is unfolded, and each corner is provided with a triangular corner protector 110, which serves as a cuboid skeleton support structure, and the stacking stability is greatly increased. The plate A 130 and the plate B 140 are unfolded and quickly restored to the original shape. The middle end ring 321 provides core support, and the guide strip 322 extends to the four corners to disperse external force impact and improve local compression resistance. The moisture-proof layer 310 effectively blocks moisture, the wear-resistant layer 300 reduces the edge wear rate, and prolongs the packaging life. In addition, the plate A 130, the plate B 140, the plate C 160 and the plate D 170 are sequentially provided with a wear-resistant layer 300, a moisture-proof layer 310, a hardening layer 320 and a corrugated layer 340 from outside to inside, and the hardening layer 320 located in the plate A 130 and the plate B 140 can be folded in half by hinging to facilitate storage.

[0029] Further, as shown in Figures 1-2 The inner surface of the plate A 130 and the plate B 140 extends a butt joint column 200 in the horizontal direction, which is disconnected into two sections at the fold 150. A rotary knob fastening device 210 is fixed on the fold 150, which fixes the two butt joint columns 200 so that the plate A 130 or the plate B 140 cannot be folded in half. Specifically, the butt joint column 200 forms a transverse support inside the carton body 100, cooperates with the triangular corner protector 110 and the support cross strip to form a three-dimensional reinforcement network, which significantly improves the compression resistance of the carton body 100. After the rotary knob fastening device 210 is locked, the butt joint column 200 limits the folding of the plate A 130 / plate B 140, avoiding the collapse of the parallel faces of the carton body 100 due to local stress during stacking or transportation.

[0030] Further, as shown in Figures 1-3As shown, the knob buckling device 210 is fixed on the fold part 150 by the elastic member 270; the knob buckling device 210 comprises parallel upper limiting plates 220 and lower limiting plates 230, and a partition plate 240 is arranged between the two plates to separate a left open cavity 250 and a right open cavity 260, and the left abutting column 200 is embedded into the left open cavity 250. The right abutting column 200 is embedded into the right open cavity 260, and the knob buckling device 210 is clamped with the two abutting columns 200. Specifically, the knob buckling device 210 can be fixed on the carton by the rubber band, and the rubber band has a certain deformation capacity, which will flexibly clamp the knob buckling device 210 on the abutting column 200 and also ensure that the knob buckling device 210 remains stable in the locked state. In addition, the inner end face of the knob buckling device 210 is in an open state, and the outer end face is provided with a shielding plate, the knob buckling device 210 is buckled from the inner end face and abuts against the outer end face to limit the abutting columns 200 at both ends. In addition, when it is necessary to fold the carton, the knob buckling device 210 can be flexibly pulled out and turned over by the rubber band to unlock the buckling.

[0031] Further, the corrugated layer 340 is arranged in a cross or 45° staggered manner to form a net-like supporting effect. The cross or 45° staggered arrangement of the corrugated layer 340 converts point-like support into planar support, forms a multi-directional force channel, absorbs impact energy, and reduces the damage rate of goods.

[0032] Further, as shown in the figure, Figures 4-5 Further, the fiber layer 330 is arranged between the hardening layer 320 and the corrugated layer 340, and the fiber layer 330 is composed of kraft paper mixed with carbon fiber short filaments. The carbon fiber short filaments have a high elastic modulus, can effectively absorb impact energy, and reduce vibration damage of goods during transportation.

[0033] Further, the moisture-proof layer 310 is composed of graphene oxide. The chemical formula of graphene oxide is GO. In a low-humidity environment, GO layers are tightly stacked, and the moisture-proof performance is excellent. In a high-humidity environment, GO layers can slightly expand to fill micro pores, further enhancing the barrier effect.

[0034] Further, the wear-resistant layer 300 is composed of water-based polyurethane. The introduction of the water-based polyurethane wear-resistant layer 300 significantly improves the wear resistance of the box 100, and cooperates with the moisture-proof layer 310, the fiber layer 330, and the corrugated layer 340 to realize the integrated design of "wear resistance-moisture-proof-load bearing-impact resistance".

[0035] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
