[0002] In the modern logistics and packaging industry, corrugated cardboard boxes are a commonly used packaging container, widely used in the transportation and storage of various products. However, in actual use, corrugated cardboard boxes often face various external forces of compression and impact. For example, during stacking, handling, and transportation, problems such as box deformation and damage can easily occur, thus affecting the protective effect on the product and the integrity of the packaging.

[0003] Existing corrugated cardboard boxes have certain limitations in terms of compression resistance, and cannot meet the packaging needs of some products with high strength requirements. For example, for some heavy, irregularly shaped, or fragile products, ordinary corrugated cardboard boxes are easily damaged under heavy pressure, resulting in product damage and economic losses for businesses and consumers. Therefore, we propose a high-strength compression-resistant corrugated cardboard box to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength, compression-resistant corrugated cardboard box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a high-strength, compression-resistant corrugated cardboard box.

[0025] Reference Figure 1-4 A high-strength, compression-resistant corrugated cardboard box includes a corrugated cardboard box body 1. The corrugated cardboard box body 1 includes an inner cardboard 101, a cushioning layer 102, and an outer cardboard 103. The inner cardboard 101 is disposed inside the outer cardboard 103, and a cushioning layer 102 is provided between the inner cardboard 101 and the outer cardboard 103. A reinforcing component 2 is provided between the inner cardboard 101 and the outer cardboard 103. The reinforcing component 2 includes a reinforcing corner plate 201, a reinforcing rib 1 202, and a reinforcing rib 203. Reinforcing corner plates 201 are pasted at the four corners of the corrugated cardboard box body 1, and the reinforcing corner plates 201 are located between the inner cardboard 101 and the outer cardboard 103. A reinforcing rib 1 202 is installed between two adjacent reinforcing corner plates 201 in the left-right direction, and a reinforcing rib 203 is installed between two adjacent reinforcing corner plates 201 in the front-back direction.

[0026] In this embodiment, the reinforcement component 2 also includes a support frame plate 302, which is fixedly pasted between the inner cardboard 101 and the outer cardboard 103. Multiple anti-compression rods 301 are fixedly installed at the bottom of the support frame plate 302. The bottom ends of the anti-compression rods 301 are fixedly installed on the support frame plate 302, and the multiple anti-compression rods 301 are arranged in a rectangular and equally spaced manner.

[0027] In this embodiment, the buffer layer 102 includes a first fixing cardboard 401, a second fixing cardboard 402, and a sealing strip 403. The first fixing cardboard 401 is fixedly pasted on the outside of the inner cardboard 101, and the second fixing cardboard 402 is fixedly installed on the inner wall of the outer cardboard 103. The sealing strip 403 is pasted between the first fixing cardboard 401 and the second fixing cardboard 402. The first fixing cardboard 401, the second fixing cardboard 402, and the sealing strip 403 together form a relatively closed buffer space, effectively blocking the intrusion of external dust, moisture, and other impurities.

[0028] In this embodiment, multiple V-shaped buffer cardboard 501s are fixedly connected between fixed cardboard 1 401 and fixed cardboard 2 402, and the multiple V-shaped buffer cardboard 501s are evenly spaced. Multiple bubble balls 502 are placed inside each V-shaped buffer cardboard 501, and multiple bubble balls 502 are placed between adjacent V-shaped buffer cardboard 501s. When an impact force is applied to the V-shaped buffer cardboard 501, its V-shaped structure undergoes elastic deformation, absorbing a large amount of impact energy during the deformation process. The evenly spaced multiple V-shaped buffer cardboard 501s form a multi-layered, all-around buffer system, allowing the entire buffer layer 102 to more evenly distribute the impact force. The addition of bubble balls 502 and 503 further optimizes the buffering effect. These bubble balls have good elasticity and deformation capacity.

[0029] In this embodiment, the reinforcing corner plate 201 is made of high-strength alloy cardboard with a thickness of 2-4 mm. Its surface is treated with waterproof and wear-resistant materials, and the corners of the reinforcing corner plate 201 are rounded to avoid scratching other components during installation and use, while further enhancing the pressure resistance of the corners.

[0030] In this embodiment, the V-shaped cushioning cardboard 501 is made of biodegradable honeycomb paper material. The bending angle of the V-shaped cushioning cardboard 501 is 120 degrees. This angle and structural design have been optimized through mechanical simulation, which can save materials to the greatest extent and reduce the overall weight of the carton while ensuring cushioning performance.

[0031] In this invention, the reinforcing corner plates 201 are made of high-strength material and are precisely glued to the four corners of the corrugated cardboard box body 1, greatly enhancing the load-bearing capacity of the box's corners. Simultaneously, the rational arrangement of reinforcing ribs 202 and 203 effectively reinforces the sides of the box from a mechanical perspective. They can evenly distribute the pressure acting on the sides of the box, preventing deformation caused by excessive local pressure. The coordinated work of the support frame plate 302 and the anti-pressure rods 301 provides a stable bottom support structure for the entire box. When the box carries heavy loads, the support frame plate 302 can evenly transmit the pressure to the multiple anti-pressure rods 301, which then stably transmit the pressure to the ground.

[0032] The meticulously designed cushioning layer 102 provides comprehensive protection for the items inside the carton. The fixing cardboard 1 401, fixing cardboard 2 402, and sealing strip 403 together create a relatively enclosed cushioning space, effectively preventing the intrusion of external dust, moisture, and other impurities, thus preventing these impurities from corroding the cushioning material and ensuring long-term stability of the cushioning performance. The V-shaped cushioning cardboard 501, with its unique structure, exhibits excellent cushioning performance when subjected to external impact. When impact force acts on the V-shaped cushioning cardboard 501, its V-shaped structure undergoes elastic deformation, absorbing a large amount of impact energy during the deformation process. Multiple V-shaped cushioning cardboards 501 are evenly spaced, forming a multi-layered, all-around cushioning system, allowing the entire cushioning layer 102 to more evenly distribute the impact force. Furthermore, the addition of bubble balls 1 502 and 2 503 further optimizes the cushioning effect. These bubble balls have good elasticity and deformation capacity; when impacted, they not only deform to absorb energy but also further disperse the impact force through mutual compression.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
