Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a cardboard box with good moisture-proof and breathable properties. Background Technology

[0002] In warehousing and transportation scenarios, cardboard boxes are commonly used packaging containers, and the stored items are often damaged by moisture due to humid environments. Existing cardboard boxes mostly rely on a single moisture-proof coating for moisture protection, which has the following shortcomings: First, the cardboard box is in direct contact with the ground, allowing ground moisture to easily penetrate into the interior through the bottom of the box; second, it lacks an effective air intake and exhaust system, preventing moisture from being discharged and dried in time, leading to mold growth; third, external moisture can easily enter through gaps or openings in the box, making it difficult to form an effective moisture barrier. Therefore, it is necessary to develop a cardboard box with good moisture resistance and breathability to address these shortcomings. Utility Model Content

[0003] The purpose of this utility model is to provide a cardboard box with good moisture-proof and breathable properties. By setting up a support component, it avoids contact with the ground and gets damp. It is also equipped with an air inlet drying mechanism and a one-way air outlet mechanism to block external moisture from entering and to exhaust internal moisture.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a cardboard box with good moisture-proof and breathable properties, comprising a box body, a top cover, and a bottom cover. The top cover is folded and connected to the upper edge of the box body, and the bottom cover is folded and connected to the lower edge of the box body. Moisture-proof films are attached to the inner and outer sides of the box body, the top cover, and the bottom cover. Support components are attached to the four side wall edges of the box body, the edge of the top cover, and the edge of the bottom cover. An air inlet is opened on one side wall of the box body, and an air outlet is opened on the opposite side wall. An air inlet drying mechanism is installed at the air inlet, and a one-way air outlet mechanism is installed at the air outlet.

[0006] Preferably, the support assembly includes several support blocks and an L-shaped support plate. The support blocks are evenly distributed around the edges of the top cover and the bottom cover and are fixed with double-sided adhesive. The support plates are evenly distributed at the upper and lower ends of each edge of the box and are fixed by riveting and adhesive. Both the support blocks and the support plates have a honeycomb hollow structure, and rubber moisture-proof pads are pasted at both the upper and lower ends. The two layers of moisture-proof pads are supported by the hollow structure.

[0007] Preferably, the air intake drying mechanism includes a drying box filled with silica gel desiccant or calcium chloride desiccant. The side of the drying box facing the inside of the box has several through holes, which are offset from the air intake.

[0008] Preferably, the one-way air outlet mechanism includes a one-way valve, which is fixed inside the air outlet.

[0009] Preferably, a baffle is provided on the inner side of the box near the drying box. The baffle has two locations on both sides of the drying box.

[0019] The core of this utility model is to provide a cardboard box with good moisture-proof and breathable properties. By setting up a support component, it avoids contact with the ground and gets damp. It is also equipped with an air inlet drying mechanism and a one-way air outlet mechanism to block external moisture from entering and to exhaust internal moisture.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Refer to the attached diagram. Figure 1 This is a schematic diagram of the main structure of the cardboard box with good moisture-proof and breathable properties according to this utility model; Figure 2 This is a schematic diagram of the left-side structure of the cardboard box with good moisture-proof and breathable properties according to this utility model; Figure 3 This is a right-side view of the structure of the cardboard box with good moisture-proof and breathable properties according to this utility model; Figure 4 This is a schematic diagram of the main sectional view of the cardboard box with good moisture-proof and breathable properties according to this utility model; Figure 5 This is a schematic diagram of the support block.

[0023] In one specific implementation, such as Figures 1-5 As shown, a moisture-proof and breathable cardboard box includes a box body 1, a top cover 2, and a bottom cover 3. The top cover 2 is folded and connected to the upper edge of the box body 1, and the bottom cover 3 is folded and connected to the lower edge of the box body 1 using crease lines. Moisture-proof films are laminated to the inner and outer sides of the box body 1, top cover 2, and bottom cover 3. The box body 1 is made of three-layer corrugated cardboard, providing load-bearing strength. The outer and inner walls of the box body 1 are fully laminated with PET moisture-proof film using hot melt adhesive. During lamination, it is ensured that there are no wrinkles or bubbles, and the edges of the moisture-proof film extend to the bonding surfaces of the top cover 2 and bottom cover 3, forming a continuous moisture barrier to prevent moisture penetration at the connection between the side walls and the cover. The top cover 2 and bottom cover 3 are made of the same material as the box body 1, and the inner sides are laminated with PET moisture-proof film of the same specifications. The top cover 2 is folded and connected to the upper edge of the box body 1, and the bottom cover 3 is folded and connected to the lower edge of the box body 1 using waterproof tape, further enhancing the sealing performance.

[0024] In one specific implementation, such as Figures 1-5 As shown, support components 4 are attached to the four side edges of the box 1, the edge of the top cover 2, and the edge of the bottom cover 3. These components lift the box 1, prevent ground moisture from entering, prevent slipping, and isolate the boxes 1 when arranged together, allowing for airflow between them. The support components 4 include several support blocks 401 and an L-shaped support plate 402. Four support blocks 401 are evenly distributed around the edge of the top cover 2, and four support blocks 401 are also distributed around the edge of the bottom cover 3, fixed to the top cover 2 and bottom cover 3 respectively with double-sided adhesive. One support block 401 is fixed at each of the top and bottom ends of the four side edges of the box 1, secured by a combination of rivets and adhesive. The moisture-proof pads 403 at the top and bottom ends of the support plate 402 are aligned with the support blocks 401, and the height of the support plate 402 is flush with the edge of the box 1, ensuring even force distribution when the box 1 is placed and that its height off the ground is consistent with that of the support blocks 401. The support block 401 and the support plate 402 are connected by a hollow structure 404, which is made of ABS plastic and has a honeycomb structure inside. Moisture-proof pads 403 are attached to both the top and bottom ends. The moisture-proof pads 403 are made of rubber and have diamond-shaped anti-slip patterns on the surface, which not only block ground moisture but also prevent the cardboard box from sliding.

[0025] In one specific implementation, such as Figures 1-5 As shown, an air inlet 5 is provided on one side wall of the housing 1, and an air inlet drying mechanism 7 is installed at the air inlet 5. The air inlet drying mechanism 7 includes a drying box 701, which is filled with silica gel desiccant or calcium chloride desiccant. The drying box 701 is detachably installed inside the air inlet 5. The side of the drying box 701 facing the inside of the housing 1 has several through holes 702 evenly distributed. The through holes 702 are offset from the air inlet 5 to prevent airflow from directly impacting the items and to ensure uniform diffusion of dry air.

[0026] Specifically, a baffle 9 is provided on the inner side of the housing 1 near the drying box 701. The baffle 9 has two locations on both sides of the drying box 701. The drying box 701 is fitted between the baffle 9 and the side wall of the housing 1. The upper and lower ends of the drying box 701 abut against the upper and lower end faces of the inner cavity of the housing 1 to ensure a stable installation.

[0027] In one specific implementation, such as Figures 1-5 As shown, an air outlet 6 is provided on the opposite side wall of the enclosure 1, and a one-way air outlet mechanism 8 is installed at the air outlet 6. The one-way air outlet mechanism 8 includes a one-way valve 801, which is fixed inside the air outlet 6 by bolts; the one-way valve 801 only allows the gas inside the enclosure to be discharged outward, and external gas cannot flow back in, ensuring the integrity of the moisture barrier.

[0028] When using this moisture-proof and breathable cardboard box, place the items inside the box body 1, close the top cover 2, and fasten the folding buckles. Apply waterproof tape to the buckle surfaces to enhance the seal. Place the box on the warehouse floor. At this time, the bottom cover 3 support block 401 and the lower support plate 402 of the box body 1 are lifted off the box body 1, and the moisture-proof mat 403 contacts the ground with its anti-slip texture to prevent slipping. Outside air enters the drying box 701 through the air inlet 5, is dried by the desiccant, and then enters the box through the through hole 702. Moisture or residual moisture from the items inside the box, under the pressure difference between the inside and outside of the box, pushes the one-way valve 801 to open, and is discharged to the outside through the air outlet 6, forming a continuous cycle of dry air intake and moisture exhaust, maintaining a dry environment inside the box.

[0029] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
