Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically to a cardboard box structure with an inner lining and cushioning protection function. Background Technology

[0002] Colored cardboard boxes are a common packaging material widely used in product transportation and sales. They are typically made of multi-layered cardboard and printed with brightly colored patterns and text, providing not only good protection but also attracting consumer attention. Colored cardboard boxes can be designed in various shapes and sizes to meet diverse packaging needs. Their advantages include being lightweight, environmentally friendly, recyclable, and offering good moisture and shock resistance, making them widely used in industries such as electronics, food, and gifts.

[0003] Patent CN217754965U discloses a cardboard box with a cushioning protection structure, including a cardboard box body. The cardboard box body includes an outer shell, four anti-collision corner guards, an inner shell, a placement pad, and an air bladder. The outer shell is fitted onto the outer side of the inner shell. Anti-collision corner guards are fixedly installed on the four sides of the outer shell. An air bladder is connected to the connection between the outer shell and the inner shell. A placement pad is fixedly installed at the bottom of the inner wall of the inner shell. The outer shell includes a waterproof paper frame, a film bubble frame, and a connecting frame. The inner shell includes a foam frame, an air column bag frame, and an inner paper frame. This utility model provides a cardboard box with a cushioning protection structure. By setting an outer shell, an inner shell, and an air bladder, the air bladder supports the inner shell from the outside, preventing the cushioning force from being transmitted to the inner shell and causing deformation of the inner shell. The gas filled in the film bubble frame on the outer shell cushions external forces, preventing deformation of the outer shell, improving the cushioning capacity of the cardboard box body, preventing deformation or damage to the items inside the cardboard box, and reducing the transportation cost of the cardboard box.

[0004] The aforementioned existing technology uses airbags to support the outer side of the inner shell, preventing the transmission of cushioning force to the inner shell and thus preventing deformation. The gas filled in the thin film bubble frame of the outer shell can effectively buffer external forces, thereby improving the cushioning capacity of the carton body and reducing the risk of damage to the items inside. However, this technology has some shortcomings in practical applications. For example, the use of airbags requires an external air supply device through an air inlet pipe, and the air inlet and exhaust pipes protrude from the outer side of the carton body, affecting the handling and stacking of the carton and causing inconvenience to users. In view of this, we propose an inner-lined color box carton structure with cushioning protection function, aiming to solve these problems in the existing technology and improve the convenience and safety of packaging. Summary of the Invention

[0005] The purpose of this invention is to provide a linerboard carton structure with cushioning and protection functions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A lined color box carton structure with cushioning protection function includes a carton, with inner flaps on the left and right sides of the top of the carton and outer flaps on the front and rear sides of the top of the carton. The carton is used to provide external support and overall structural frame, and is closed by the inner flaps and outer flaps. The bottom of the inner wall of the cardboard box is equipped with a rubber pad to absorb the impact force from the bottom and reduce the transmission of vibration to the inner cardboard box. The inner cardboard box is placed on top of the rubber pad. The inner cardboard box serves as a secondary packaging container and uses honeycomb cardboard and pearl cotton to achieve multi-level cushioning. The inner wall of the inner cardboard box is lined with a sponge liner to prevent friction damage to the surface of the items. Fragile items placed inside the sponge liner can be further protected by filling with foam or other protective materials. The top of the inner cardboard box is equipped with a sponge top pad to provide elastic cushioning at the top.

[0007] Preferably, when the carton is closed, the inner side of the inner flap abuts against the top of the sponge top pad.

[0008] Preferably, the outer wall of the sponge top pad is attached to the inner wall of the carton, and the sponge top pad enhances the overall stability by attaching to the inner wall of the carton.

[0009] Preferably, the four sides of the inner cardboard box are all made of honeycomb paperboard. The honeycomb paperboard disperses pressure and improves compressive strength through its honeycomb hollow structure. The sponge lining is adhered to the inner wall of the inner cardboard box.

[0010] Preferably, the outer side of the inner cardboard box is evenly distributed with multiple pearl cotton fibers, which are arranged vertically to absorb lateral impact forces.

[0011] Preferably, the side of the pearl cotton furrowed away from the inner cardboard box abuts against the inner wall of the carton, and the pearl cotton achieves lateral cushioning by tightly abutting against the inner wall of the carton.

[0012] Preferably, the pearl cotton has multiple equally spaced strip openings on the side away from the inner cardboard box. The strip openings optimize the elastic cushioning effect of the pearl cotton by increasing the deformation space.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This cushioned and protective inner-lined color box carton structure, through the synergistic effect of pearl cotton, honeycomb cardboard and sponge lining, eliminates the need for external airbags or inflation equipment, simplifies the structural design, avoids the inconvenience of handling and stacking caused by the exposed air intake pipe of traditional airbags, and significantly improves the convenience and safety of packaging.

[0014] 2. The inner lining color box structure with cushioning protection adopts a multi-layer cushioning design to form a multi-level protection system, which effectively reduces the risk of damage to the goods by external forces from different directions during transportation, and is especially suitable for the protection of fragile and high-value goods.

[0015] 3. The inner lining color box structure with cushioning protection uses the honeycomb hollow structure of honeycomb cardboard and the strip opening design of pearl cotton to reduce the overall weight while ensuring compression resistance. In addition, all materials are lightweight and recyclable, meeting environmental protection requirements. Attached Figure Description

[0019] Please see Figures 1-4 This utility model provides a technical solution: The inner lining color box carton structure with cushioning protection function includes a carton 100. The left and right sides of the top of the carton 100 are provided with inner flaps 110, and the front and rear sides of the top of the carton 100 are provided with outer flaps 120. The carton 100 is used to provide external support and overall structural frame, and is closed by the inner flaps 110 and the outer flaps 120. A rubber pad 200 is placed at the bottom of the inner wall of the cardboard box 100. The rubber pad 200 is used to absorb the impact force at the bottom and reduce the vibration transmitted to the inner cardboard box 300. The inner cardboard box 300 is placed on top of the rubber pad 200. The inner cardboard box 300 serves as a secondary packaging container and achieves multi-level cushioning through honeycomb cardboard 310 and pearl cotton 400. The inner wall of the inner cardboard box 300 is provided with a sponge liner 500. The sponge liner 500 is used to prevent friction damage to the surface of the items. Fragile items placed inside the sponge liner 500 can be further protected by filling with foam particles or other protective materials. A sponge top pad 600 is placed on top of the inner cardboard box 300 to provide elastic cushioning at the top.

[0020] In this embodiment, when the carton 100 is closed, the inner side of the inner flap 110 abuts against the top of the sponge top pad 600.

[0021] Specifically, the outer wall of the sponge top pad 600 is attached to the inner wall of the cardboard box 100, and the sponge top pad 600 enhances the overall stability by attaching to the inner wall of the cardboard box 100.

[0022] Furthermore, the four sides of the inner cardboard box 300 are all made of honeycomb paperboard 310. The honeycomb paperboard 310 disperses pressure through its honeycomb hollow structure, thereby improving its compressive strength. The sponge liner 500 is bonded to the inner wall of the inner cardboard box 300.

[0023] Furthermore, multiple pearl cotton 400s are evenly distributed on the outer side of the inner cardboard box 300. The pearl cotton 400s are arranged vertically and absorb lateral impact forces.

[0024] Furthermore, the side of the pearl cotton 400 away from the inner cardboard box 300 abuts against the inner wall of the carton 100, and the pearl cotton 400 achieves lateral cushioning by closely abutting against the inner wall of the carton 100.

[0025] Furthermore, multiple equally spaced slots 401 are provided on the side of the pearl cotton 400 away from the inner cardboard box 300. The slots 401 optimize the elastic cushioning effect of the pearl cotton 400 by increasing the deformation space. In this embodiment, the inner-lined color box carton structure with cushioning protection function is used as follows: First, a rubber pad 200 is placed at the bottom of the inner wall of the carton 100 to absorb the vertical impact force generated during transportation; then, the inner carton 300 is placed on top of the rubber pad 200. The four sides of the inner carton 300 are made of honeycomb cardboard 310, which disperses external pressure through the honeycomb hollow structure; a sponge liner 500 is adhered to the inner wall of the inner carton 300 to prevent friction damage to the surface of the item, and the space between the item and the sponge liner 500 can be filled with foam blocks or foam particles; multiple pearl cotton 400s are vertically and evenly distributed on the outer side of the inner carton 300, with the pearl cotton 400s being far away from the inner carton 300. One side abuts against the inner wall of the carton 100, absorbing lateral impact through high-density foam material. The strip-shaped opening 401 on the surface of the pearl cotton 400 optimizes the elastic cushioning effect by increasing the deformation space. Finally, the sponge top pad 600 is placed on top of the inner carton 300. When the carton 100 is closed, the inner flap 110 and the outer flap 120 together press the sponge top pad 600, so that its outer wall fits against the inner wall of the carton 100 to enhance stability. At the same time, the elastic compression of the sponge top pad 600 provides top cushioning protection. After packaging, the carton 100 forms a sealed structure through the closure of the inner flap 110 and the outer flap 120, ensuring that the contents are protected from damage by external forces in multiple directions during transportation.
