Description

Technical Field

[0001] This utility model belongs to the field of cardboard box technology, and in particular relates to a high-pressure load-bearing packaging cardboard box for cigarettes. Background Technology

[0002] In modern packaging, cigarettes are neatly placed in cigarette boxes after production, and these boxes are then arranged in cardboard boxes for packaging. Corrugated cardboard boxes are commonly used in the market. However, traditional corrugated cardboard boxes, due to their simple structure (mostly single- or double-layered corrugated), are prone to deformation and collapse when stacked or under pressure, making them unsuitable for packaging heavy goods (such as machine parts, home appliances, and industrial raw materials). Humid environments can easily cause cardboard boxes to soften and break, and long-term friction accelerates surface wear, affecting their lifespan. While some reinforced cardboard boxes (such as those reinforced with steel straps) increase load-bearing capacity, they are expensive and heavy, which is not in line with environmental protection trends. Utility Model Content

[0003] The purpose of this utility model is to provide a high-pressure load-bearing packaging carton for cigarettes, which aims to solve the technical problems of existing packaging cartons being easily deformed and prone to moisture.

[0004] To achieve the above objectives, this utility model provides a high-pressure load-bearing packaging carton for cigarettes, comprising a square frame with openings at the top and bottom. Two sets of symmetrical folding plates A and B extend from the bottom opening of the square frame. A folding plate C is bent and positioned at the upper left opening of the square frame. A folding plate D extends downwards perpendicularly from the other end of folding plate C. A through-hole connecting groove is provided on the arc-shaped edge between folding plate C and folding plate D. Several empty slots are provided at the upper right opening of the square frame. Bendable and rotatable hooks are connected to these empty slots, extending into the empty slots to form a snap-fit ​​connection. The square frame consists of a fiber layer, a corrugated layer, a moisture-proof layer, and a wear-resistant layer, arranged sequentially from the inside out.

[0005] Furthermore, the two ends of the folded plate C near the folded plate D are provided with support plates that abut against the square frame; the square frame is provided with support grooves at the positions corresponding to the support plates.

[0006] Furthermore, the square frame is connected to adjacent sides by folding corner protectors, which include a first horizontal bar, a second horizontal bar, and a square block that can be folded in half. One end of the first horizontal bar is connected to one inner side of the square frame, and the other end is connected to one end of the square block. One end of the second horizontal bar is connected to the other adjacent side of the square frame, and the other end is connected to the other end of the square block.

[0007] Furthermore, the square frame also includes a third horizontal bar, one end of which is connected to the inner surface of the folded plate A, and the other end is connected to the part of the square block that is folded in half.

[0008] Furthermore, the fiber layer is composed of kraft paper mixed with carbon fiber short filaments.

[0009] Furthermore, the corrugated layers are arranged orthogonally or at 45° angles to form a mesh support effect.

[0010] Furthermore, the moisture-proof layer is composed of graphene oxide.

[0011] Furthermore, the wear-resistant layer is composed of water-based polyurethane.

[0012] The high-pressure load-bearing packaging cigarette cartons provided in this utility model embodiment have at least one of the following technical effects:

[0013] In this design, the bottom surface is assembled first. The folding plates A / B at the lower opening are folded inwards by 90° to form the bottom support surface. The cigarette box is placed inside the packaging box. The folding plate C at the upper left opening is folded downwards until it is perpendicular to the frame. Then, the folding plate D is inserted into the connecting groove along its curved edge to form a fixed angle. The hook at the upper right opening is folded so that it extends into the empty slot and engages. The top is then sealed, completing the assembly. The fiber layer and the high-strength corrugated layer work together to increase the load-bearing capacity compared to traditional cardboard boxes. The bottom folding plates A / B form a double-layer support structure, distributing pressure and preventing bottom collapse. The curved connecting groove design of folding plates C / D fixes the top sealing angle, preventing loosening during transportation. The elastic engagement of the hook with the empty slot provides additional fixing force, ensuring the box remains stable under vibration. Hot-pressing composite technology is used to integrate the fiber layer, corrugated layer, moisture-proof layer, and wear-resistant layer, providing wear resistance and water resistance, and preventing interlayer delamination.

[0027] In one embodiment of this utility model, a high-pressure load-bearing packaging cigarette carton is provided, including a square frame 100 with openings at the top and bottom. Two sets of symmetrical folding plates A110 and B120 extend from the lower opening of the square frame 100, respectively. A folding plate C130 is provided at the upper left opening of the square frame 100 and bent thereto. A folding plate D140 extends downward and is perpendicular to it at the other end of the folding plate C130. A through connecting groove 150 is provided on the arc-shaped edge between the folding plate C130 and the folding plate D140. A plurality of empty slots 160 are provided at the upper right opening of the square frame 100. A bendable and rotatable hook part 170 is connected to the empty slot 160 and extends into the empty slot 160 to form a snap-fit. The square frame 100 is composed of a fiber layer 200, a corrugated layer 210, a moisture-proof layer 220 and a wear-resistant layer 230 from the inside to the outside.

[0028] Specifically, the bottom surface is assembled first. The folding plate A110 / B at the lower opening is folded inward by 90° to form the bottom support surface. The cigarette box is placed into the packaging box. The folding plate C130 at the upper left opening is folded downward until it is perpendicular to the frame. Then, the folding plate D140 is inserted into the connecting groove 150 along the curved edge to form a fixed angle. The hook part 170 at the upper right opening is folded so that it extends into the empty groove 160 and engages. The top is sealed to complete the assembly. The fiber layer 200 and the high-strength corrugated layer 210 work together to improve the load-bearing capacity compared to traditional cardboard boxes. The bottom folding plate A110 / B forms a double-layer support structure to distribute pressure and prevent the bottom from collapsing. The curved connecting groove 150 design of the folding plate C130 / D fixes the top sealing angle and prevents loosening during transportation. The elastic engagement of the hook part 170 and the empty groove 160 provides additional fixing force to ensure the stability of the box in a vibration environment. Using hot-press composite technology, the fiber layer 200, corrugated layer 210, moisture-proof layer 220 and wear-resistant layer 230 are integrally molded, providing wear resistance and water resistance, and avoiding interlayer delamination.

[0029] Furthermore, the folded plate C130 has support plates 300 at both ends near the folded plate D140 that abut against the square frame 100; the square frame has support grooves 310 at the positions corresponding to the support plates 300. Specifically, the support plates 300 abut against the inner wall of the square frame 100 to form a triangular support structure, preventing the folded plate C130 from sagging.

[0030] Furthermore, folding corner protectors 400 are connected between adjacent sides of the square frame 100. Each folding corner protector 400 includes a first horizontal bar 410, a second horizontal bar 420, and a square block 430 that can be folded in half. One end of the first horizontal bar 410 is connected to one inner surface of the square frame 100, and the other end is connected to one end of the square block 430. One end of the second horizontal bar 420 is connected to the other adjacent side of the square frame 100, and the other end is connected to the other end of the square block 430. The square frame 100 also includes a third horizontal bar 440, one end of which is connected to the inner surface of the folding plate A110, and the other end is connected to the folded portion of the square block 430. Specifically, during the folding assembly of the box, the first horizontal bar 410, the second horizontal bar 420, and the square block 430 are in a flat state; during assembly, the square block 430 changes from a folded state to a flat state, forming a locking structure, thus creating a triangular support between the square frame 100 and the folding plates A110 / B. Provides comprehensive shock protection, reducing cargo damage caused by collisions during transportation.

[0031] Furthermore, the fiber layer 200 is composed of kraft paper mixed with carbon fiber short filaments. Specifically, the carbon fiber short filaments have a high elastic modulus, which can effectively absorb impact energy and reduce vibration damage to goods during transportation.

[0032] Furthermore, the corrugated layer 210 has orthogonal or 45° staggered flutes, forming a mesh support effect. Specifically, the orthogonal or 45° staggered flute arrangement transforms point support into surface support, forming multi-directional force channels, absorbing impact energy, and reducing cargo damage rate.

[0033] Furthermore, the moisture barrier 220 is composed of graphene oxide, the chemical formula of which is GO. In low humidity environments, the GO sheets are tightly stacked, resulting in excellent moisture-proof performance. In high humidity environments, the GO sheets can expand slightly, filling micropores and further enhancing the barrier effect.

[0034] Furthermore, the wear-resistant layer 230 is composed of water-based polyurethane. The introduction of the water-based polyurethane wear-resistant layer 230 significantly improves the wear resistance of the box. At the same time, it works in synergy with the moisture-proof layer 220, fiber layer 200 and corrugated layer 210 to achieve an integrated design of "wear resistance-moisture-load-bearing-impact resistance".

[0035] The above description is only a preferred embodiment of the present utility model and is 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.
