Technical Field
[0001] This utility model relates to the field of cardboard box technology, specifically to a moisture-proof and pressure-resistant structure for color box cardboard boxes. Background Technology
[0002] Color boxes / cartons are a widely used packaging form in the modern packaging industry, characterized by their attractive appearance, lightweight design, and ease of processing. They are widely used for packaging food, daily necessities, electronic products, and gifts. Color boxes typically use cardboard or corrugated paper as the main material, complemented by exquisite printed designs, effectively enhancing the product's perceived quality and market competitiveness. However, due to the high hygroscopicity of cardboard and corrugated paper, they easily absorb moisture from the air in humid environments, causing the boxes to become soft and lose their structural strength and protective performance. To address this issue, existing color boxes / cartons are usually covered with a moisture-proof film to reduce the direct impact of moisture on the box itself. However, relying solely on the external moisture-proof film is insufficient to completely prevent moisture intrusion, especially in high-humidity environments, where moisture can still enter the box through gaps or other means, directly damaging the contents.
[0003] Patent CN218369514U discloses a pressure-resistant color box with a moisture-proof structure, including a main box body with a lid. The main box body contains a partition frame mechanism with reinforcement and moisture-proof functions. An insert plate body is flipped along one set of folds, and then one end of the insert plate body is flipped along another set of folds, aligning one end of the insert plate body with a slot. One end of the insert plate body is pushed into the slot, and a lever is engaged, causing one end of the insert plate body to be fully inserted into the slot. Finally, the lid is placed on the main box body. A Z-shaped insert plate seals the desiccant in the storage cavity. Since edible items are placed inside the partition frame body, the desiccant is separated from the edible items. Therefore, the combination of the partition frame body and the Z-shaped insert plate not only prevents children from accidentally ingesting the desiccant, but also provides support to the interior of the main box body, reinforcing it and enhancing its pressure resistance.
[0004] The aforementioned existing technology effectively isolates the desiccant from edible items through a partition frame mechanism, avoiding the safety hazard of children accidentally ingesting the desiccant. Simultaneously, the partition frame body and the Z-shaped insert plate work together to support and reinforce the interior of the main box, enhancing the box's pressure resistance. However, this design also has certain limitations. Specifically, the partition frame body adopts a grid-like structure. While this structure provides pressure resistance and separation, it significantly occupies internal space within the main box, resulting in a substantial reduction in the capacity for storing items. This is particularly problematic in applications where internal space is critical, significantly limiting its efficiency. Therefore, we propose a moisture-proof and pressure-resistant structure for color boxes and cartons. Utility Model Content
[0005] The purpose of this utility model is to provide a moisture-proof and pressure-resistant structure for color boxes and cartons to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The moisture-proof and pressure-resistant structure of the color box carton includes a box body, with a lid fitted on the top of the box body. Both the outer surfaces of the box body and the lid are coated with a waterproof coating, which can be a water-based acrylic coating. This coating is used to prevent moisture from damaging the box body and lid without affecting the appearance of the color box carton, thereby enhancing its moisture-proof performance. The box body is equipped with moisture-proof and pressure-resistant components, which are used to reinforce the structure of the box body and contain desiccants to absorb moisture inside the box, thereby enhancing the pressure resistance of the box body and further improving the moisture-proof effect.
[0008] The moisture-proof and pressure-resistant components include four rectangular vertical tubes arranged in a matrix. The four rectangular vertical tubes are located at the four corners of the inner wall of the box, providing vertical support for the box and preventing deformation of the corners due to external pressure. Between two rectangular vertical tubes arranged front to back, there are multiple first reinforcing strips arranged vertically at equal intervals to enhance the pressure resistance of the box in the front-back direction. At the same time, their fit with the inner wall of the box further stabilizes the structure of the box. Between two rectangular vertical tubes arranged left to right, there are multiple second reinforcing strips arranged vertically at equal intervals to enhance the pressure resistance of the box in the left-right direction. They also work together with the rectangular vertical tubes and the first reinforcing strips to further improve the stability and pressure-bearing capacity of the overall structure.
[0009] A reinforcing plate is placed inside the rectangular vertical tube to enhance the strength of the rectangular vertical tube body and prevent it from deforming, thereby improving the load-bearing capacity of the overall moisture-proof and pressure-resistant components. A rectangular sliding plate is provided at the bottom of the reinforcing plate. The outer wall of the rectangular sliding plate is in contact with the inner wall of the rectangular vertical tube. When the desiccant needs to be replaced, simply pull the reinforcing plate upwards, and the rectangular sliding plate can carry the desiccant inside the rectangular vertical tube upwards, making it convenient for the user to replace the desiccant.
[0010] Desiccant is placed inside the rectangular vertical tubes and on both sides of the reinforcing vertical plate to absorb moisture inside the box and further prevent moisture from damaging the internal items. Multiple vent holes a are opened on the opposite sides of the two rectangular vertical tubes arranged front to back, and multiple vent holes b are opened on the opposite sides of the two rectangular vertical tubes arranged left to right. Ventilation holes a and b are used to enhance air circulation inside the box, improve the moisture absorption efficiency of the desiccant, and prevent moisture from accumulating.
[0011] Preferably, a rubber sealing liner is bonded to the side of the inner wall of the lid. The inner wall of the rubber sealing liner is tightly fitted to the outer wall of the box to form an effective sealing structure, preventing moisture from entering the box through the gap between the lid and the box, and further improving the moisture-proof effect.
[0012] Preferably, a pressure-resistant base plate is placed at the bottom of the inner wall of the box to support the items and enhance the pressure resistance of the bottom of the box. The pressure-resistant base plate has a first L-shaped clearance opening at each of its four corners. The bottom ends of the four rectangular vertical tubes are respectively located in the four first L-shaped clearance openings. The first L-shaped clearance openings are used to accommodate the bottom ends of the rectangular vertical tubes, ensuring that the rectangular vertical tubes can be placed stably on the pressure-resistant base plate, thereby preventing them from moving or tilting.
[0013] Preferably, each of the four rectangular vertical tubes has an L-shaped positioning block on its outer wall near the bottom. The bottom of the L-shaped positioning block abuts against the top of the pressure-resistant base plate, further improving the stability of the pressure-resistant base plate.
[0014] Preferably, each of the four rectangular vertical tubes has an L-shaped support block on its outer wall near the top. The top of the four L-shaped support blocks jointly supports a pressure-resistant top plate. The pressure-resistant top plate is used to disperse the external pressure on the top of the box and protect the internal items from damage. Each of the four corners of the pressure-resistant top plate has a second L-shaped clearance opening to avoid the rectangular vertical tubes, so that the pressure-resistant top plate can be matched and installed with the rectangular vertical tubes to ensure the stability of the overall structure.
[0015] Preferably, the opposite sides of the two first reinforcing strips arranged on the left and right sides respectively fit against the left and right sides of the inner wall of the box, which is used to further stabilize the position of the first reinforcing strips and improve the compressive strength of the left and right sides of the box. The front and rear ends of the first reinforcing strips are provided with first inserts, and the opposite sides of the two rectangular vertical tubes arranged on the front and rear sides are provided with first slots for the first inserts to be inserted, which is used to achieve a stable connection between the first reinforcing strips and the rectangular vertical tubes.
[0016] Preferably, the opposite sides of the two second reinforcing strips arranged in a front-to-back manner are respectively attached to the front and back sides of the inner wall of the box to further stabilize the position of the second reinforcing strips and improve the compressive strength of the front and back sides of the box. The left and right ends of the second reinforcing strips are provided with second inserts, and the opposite sides of the two rectangular vertical tubes arranged in a left-to-right manner are provided with second slots for the second inserts to be inserted, so as to achieve a stable connection between the second reinforcing strips and the rectangular vertical tubes.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The moisture-proof and pressure-resistant structure of this color box carton features a rubber sealing liner bonded to the inner wall of the lid, forming a sealed structure to prevent moisture from entering the carton through the gap between the lid and the carton body. By installing moisture-proof and pressure-resistant components inside the carton, the internal structure is reinforced, significantly enhancing the carton's pressure resistance. Rectangular vertical tubes are distributed at the four corners of the carton, providing vertical support and preventing deformation of the corners under external pressure. The first and second reinforcing strips work together to enhance the carton's pressure resistance in the front-back and left-right directions, while also working in conjunction with the rectangular vertical tubes to improve the overall structural stability and pressure-bearing capacity, thus enabling the color box carton to withstand greater stacking pressure.
[0019] 2. The moisture-proof and pressure-resistant structure of this color box carton, through the layout design of rectangular vertical tubes, first reinforcing strips and second reinforcing strips, achieves reinforcement and moisture-proof functions while avoiding the problem of existing grid-shaped partition frame structures occupying a large amount of internal space. The rectangular vertical tubes are only arranged at the four corners of the box, and the first and second reinforcing strips are arranged at equal intervals, maximizing the preservation of effective internal space and improving the volume ratio of items. It is particularly suitable for scenarios with high internal space requirements.
[0020] 3. The color box carton has a moisture-proof and pressure-resistant structure. The rectangular vertical tube is designed with a reinforcing vertical plate and a rectangular sliding plate. When the desiccant needs to be replaced, the user only needs to pull the reinforcing vertical plate upwards. The rectangular sliding plate can move the desiccant in the rectangular vertical tube upwards, making it convenient for the user to take out and replace the desiccant, thus improving the user experience.
[0021] 4. The color box carton has a moisture-proof and pressure-resistant structure. The side walls of the rectangular vertical tubes are designed with ventilation holes a and b. These ventilation holes help to enhance the air circulation inside the box, improve the moisture absorption efficiency of the desiccant, and further improve the moisture-proof effect inside the box.
[0022] 5. The moisture-proof and pressure-resistant structure of this color box carton features an L-shaped support block at the top of the rectangular vertical tube supporting the pressure-resistant top plate, and an L-shaped positioning block at the bottom of the rectangular vertical tube working in conjunction with the pressure-resistant bottom plate. This design effectively disperses external pressure, evenly transferring the pressure acting on the top of the box to the rectangular vertical tube and the pressure-resistant bottom plate, thereby protecting the items inside the box from damage or deformation. It is particularly suitable for logistics transportation or long-term storage scenarios. Attached Figure Description

Insert the second slot 401 to secure it, ensuring that the first reinforcing strip 41 and the second reinforcing strip 42 are arranged equidistantly vertically to form a stable moisture-proof and pressure-resistant component 4. Next, install the four rectangular vertical tubes 40 at the four corners of the pressure-resistant base plate 5, so that the bottom end of the rectangular vertical tube 40 is embedded in the first L-shaped clearance opening 50, and ensure that the bottom L-shaped positioning block 404 of the rectangular vertical tube 40 is in contact with and fits against the top of the pressure-resistant base plate 5 for stable positioning. Then, place an appropriate amount of desiccant inside each rectangular vertical tube 40 along both sides of the reinforcing vertical plate 43 to absorb moisture and protect the internal items. Finally, place the items in the box. 1. Next, place the pressure-resistant top plate 6 on top of the four rectangular vertical pipes 40, ensuring that the second L-shaped clearance openings 60 at the four corners of the pressure-resistant top plate 6 match the top of the rectangular vertical pipes 40.

Finally, place the box cover 2 on top of the box body 1, ensuring that the rubber sealing liner 3 on the inner wall of the box cover 2 adheres to the outer wall of the box body 1 to form a sealed structure. During use, the waterproof coating on the outer surfaces of the box body 1 and the box cover 2 prevents external moisture from entering, and the rubber sealing liner 3 further seals and protects against moisture. The moisture-proof and pressure-resistant bottom plate 5 provides bottom support and supports the internal items. The rectangular vertical tube 40 provides vertical support for the box body 1.
