Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a moisture-proof and pressure-resistant packaging box. Background Technology

[0002] In the circulation of goods, packaging boxes are widely used as a key carrier in the logistics and storage process. They not only provide physical protection for products, but also allow for identification and classification by printing product information, barcodes, and operating instructions on the boxes.

[0003] Paper packaging boxes are currently the most commonly used type of packaging box. However, existing paper packaging boxes are easily affected by environmental factors during use, especially changes in external humidity and load-bearing pressure. When paper packaging boxes absorb too much moisture or bear too much pressure, the box body will deform or even the box structure will collapse, failing to effectively protect the products inside.

[0004] Therefore, in order to meet the needs of transport packaging, it is necessary to provide a moisture-proof and pressure-resistant packaging box. Utility Model Content

[0005] In view of the existing technology's need for moisture-proof and pressure-resistant packaging boxes, this utility model provides a moisture-proof and pressure-resistant packaging box.

[0006] A moisture-proof and pressure-resistant packaging box includes a box body. A cover plate is fixedly connected to each of the opposite sides of the top opening of the box body, and a liner plate for use with the cover plate is fixedly connected to each of the other opposite sides of the top opening of the box body. A pressure-resistant column is inserted into each corner of the box body. Each pressure-resistant column includes a column body and several moisture-proof particles filled within the column body. A hydrophobic film is provided on both the inner and outer surfaces of the box body, and a cavity is formed within the box body. A moisture-proof pad for absorbing moisture within the cavity is provided at the bottom of the cavity. The box body and the column body are both made of cardboard, and the cardboard includes a core layer and an inner surface layer and an outer surface layer respectively disposed on both sides of the core layer. The core layer includes a core and a first trapezoidal corrugated plate and a second trapezoidal corrugated plate respectively bonded to both sides of the core, with the corrugation direction of the first trapezoidal corrugated plate perpendicular to the corrugation direction of the second trapezoidal corrugated plate. An antibacterial layer is also provided between the outer surface layer and the core layer.

[0007] Furthermore, the column includes an inner column and an outer column that wraps around the inner column. The outer surface of the inner column is provided with several connecting blocks that connect to the inner surface of the outer column, and a receiving cavity is formed between the inner column and the outer column, and the moisture-proof particles are filled in the receiving cavity.

[0008] Furthermore, the moisture-proof mat includes a moisture-proof rubber board, the moisture-proof rubber board has a cavity, and the cavity is provided with a plurality of elastic rubber boards that separate the cavity.

[0009] Furthermore, a support frame is provided inside the cavity. The support frame includes several support rods disposed at the corners of the cavity. The first ends of adjacent support rods are connected by a first connecting rod, and the second ends of adjacent support rods are connected by a second connecting rod, so that the first connecting rod, the second connecting rod, and the corresponding support rod together form a rectangular frame.

[0010] Furthermore, both the inner and outer surface layers include a honeycomb structure plate and an outer panel bonded to one side of the honeycomb structure plate.

[0011] Furthermore, an ink printing layer is provided between the outer surface of the box and the hydrophobic film.

[0012] Furthermore, the core layer, inner surface layer, and outer surface layer are all made of stone paper.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a moisture-proof and pressure-resistant packaging box. By inserting pressure-resistant columns into the corners of the box, the overall pressure resistance of the box is significantly improved. Furthermore, the cardboard core layer of the box body is equipped with mutually perpendicular first and second trapezoidal corrugated plates, which helps to enhance the cardboard's resistance to compression and torsion, further improving the pressure resistance of the box body and columns, and enhancing the overall structural strength of the box. Simultaneously, by filling the columns with moisture-proof particles, applying a hydrophobic film to the inner and outer surfaces of the box, and having a moisture-proof pad at the bottom of the cavity, multi-directional barriers are achieved to prevent external moisture from absorbing too much moisture, effectively preventing the box from softening and deforming, and further ensuring the dryness and safety of the products inside the box.

[0026] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] refer to Figure 1 As shown, a moisture-proof and pressure-resistant packaging box includes a box body 1. A cover plate 2 is fixedly connected to each of the opposite sides of the upper opening of the box body 1, and a liner plate 3, which works in conjunction with the cover plate 2, is fixedly connected to the other opposite sides of the upper opening of the box body 1. In actual use, the liner plate 3 is first folded inward, and then the cover plate 2 is folded inward to close the upper opening of the box body 1.

[0028] Specifically, refer to Figure 1 and Figure 2As shown, a pressure-resistant column 4 is inserted into each corner of the box body 1; the pressure-resistant column 4 includes a column body 41 and a plurality of moisture-proof particles 42 filled inside the column body 41. In this embodiment, the moisture-proof particles 43 are silica gel particles or activated carbon particles.

[0029] Anti-compression columns 4 are inserted at the corners of the box body 1. The column structure 41 provides additional support for the box body 1, which can significantly enhance the compressive strength of the corners of the box body 1. This reduces the risk of overall deformation and damage to the box body 1 due to corner deformation caused by external pressure or collision during stacking and transportation, thereby improving the overall structural stability and durability of the box body 1. Moisture-proof particles 43 can absorb moisture from the inside and surrounding environment of the box body 1, reducing the humidity inside the box body 1. This can protect the products inside the box from moisture damage and also prevent the box body 1 from absorbing too much moisture, which would lead to a decrease in overall compressive strength and structural deformation of the box body 1, thus extending the service life of the box body 1.

[0030] The column 41 includes an inner column 411 and an outer column 412 that wraps around the inner column 411. The outer surface of the inner column 411 is provided with a plurality of connecting blocks 413 that are connected to the inner surface of the outer column 412. A receiving cavity 414 is formed between the inner column 411 and the outer column 412, and the moisture-proof particles 43 are filled in the receiving cavity 414.

[0031] By setting up a receiving cavity 414 and filling it with moisture-proof particles 43, an independent moisture-proof layer is formed, effectively blocking the penetration of moisture from the external environment and preventing moisture from directly contacting the internal structure of the column 41, thus ensuring the stability of the column 41's structure during long-term use. The setting of the connecting block 413 can disperse and transmit external forces, which is beneficial to improving the column 41's resistance to compression, bending, and impact, and extending its service life.

[0032] refer to Figure 3 and Figure 4 As shown, a hydrophobic film 5 is provided on both the inner and outer surfaces of the box 1, and a cavity (not shown in the figure) is formed inside the box 1. A moisture-proof pad 6 for absorbing moisture inside the cavity is provided at the bottom of the cavity. In this embodiment, the hydrophobic film 5 is a solid paraffin film layer or a polyethylene coating.

[0033] The hydrophobic film 5 on the inner and outer surfaces of the cabinet 1 and the moisture-proof pad 6 inside the cavity form a gradient protection, which can effectively prevent environmental moisture from invading and damaging the structure of the cabinet 1, achieve dryness inside the cabinet 1, and improve the moisture-proof effect of the cabinet.

[0034] Among them, reference Figure 1 and Figure 6As shown, a support frame 7 is also provided inside the cavity. The support frame 7 includes a plurality of support rods 71 ​​disposed at the corners of the cavity. The first ends of adjacent support rods 71 ​​are connected by a first connecting rod 72, and the second ends of adjacent support rods 71 ​​are connected by a second connecting rod 73, so that the first connecting rod 72, the second connecting rod 73 and the corresponding support rod 71 together form a rectangular frame.

[0035] Multiple rectangular frames form a support frame 7 inside the box 1, thereby reinforcing the structure of the box 1, improving its structural stability, effectively enhancing its resistance to pressure when stacking the boxes, and preventing the boxes from deforming due to excessive pressure during stacking, which could affect subsequent storage. In actual use, this support frame 7 can be disassembled and reused in different boxes.

[0036] refer to Figure 3 and Figure 5 As shown, the moisture-proof mat 6 includes a moisture-proof rubber sheet 61, with a cavity 62 inside the moisture-proof rubber sheet 61. The cavity 62 is further divided by several elastic rubber sheets 63. The moisture-proof rubber sheet 61 serves to prevent moisture absorption; the elastic rubber sheets 63 divide the cavity 62 into independent units, effectively dispersing the pressure and impact on the moisture-proof rubber sheet 61, thus extending the service life of the moisture-proof mat 6.

[0037] Both the box body 1 and the column body 41 are made of cardboard, which retains the advantages of paper packaging boxes such as lightness and recyclability, and meets environmental protection requirements.

[0038] refer to Figure 3 and Figure 5 As shown, the cardboard 8 includes a core layer 81 and an inner surface layer 82 and an outer surface layer 83 respectively disposed on both sides of the core layer 81; the core layer 81 includes a core 811 and a first trapezoidal corrugated plate 812 and a second trapezoidal corrugated plate 813 respectively bonded to both sides of the core 811, and the corrugation direction of the first trapezoidal corrugated plate 812 is perpendicular to the corrugation direction of the second trapezoidal corrugated plate 813.

[0039] The intersecting and perpendicular arrangement of the first trapezoidal corrugated plate 812 and the second trapezoidal corrugated plate 813 can evenly distribute external stress in all parts of the core layer 81, further enhancing the effect of dispersing the external impact force of the trapezoidal corrugated plate, thereby improving its load-bearing capacity and compressive strength, significantly improving the overall structural stability of the core layer 81, and thus improving the compressive and torsional resistance of the paperboard 8, making the paperboard 8 less prone to deformation or damage when subjected to external forces, and improving the compressive strength and cushioning performance of the paperboard.

[0040] The inner surface layer 82 and the outer surface layer 83 each include a honeycomb structure plate 821 and an outer panel 822 bonded to one side of the honeycomb structure plate 821. Specifically, the honeycomb structure plate 821 of the inner surface layer 82 is bonded to a first trapezoidal corrugated plate 812; the honeycomb structure plate 821 of the outer surface layer 83 is bonded to a second trapezoidal corrugated plate 813; and the hydrophobic film 5 is disposed on the outer surface of the outer panel 822.

[0041] The honeycomb structure panel 821 possesses excellent strength and lightweight properties, effectively distributing external loads, making the structure more stable, and significantly improving the overall load-bearing capacity of the inner surface layer 82 and the outer surface layer 83. The combination of the outer panel 822 and the honeycomb structure panel 301 enhances the overall strength of the cardboard structure and effectively resists external crushing forces.

[0042] In some embodiments, an antibacterial layer 9 is further provided between the outer surface layer 82 and the core layer 81, which can effectively inhibit bacterial growth and reduce damage to the box and internal products caused by bacteria. In this embodiment, the antibacterial layer 9 is a bamboo charcoal fiber layer or a nano-silver antibacterial layer.

[0043] In some embodiments, the core layer 81, inner surface layer 82, and outer surface layer 83 are all made of stone paper. Stone paper is a low-cost and recyclable raw material, and the resulting cardboard 8 is waterproof, moisture-proof, has high structural strength, high and low temperature resistance, and low manufacturing cost.

[0044] In some embodiments, an ink printing layer (not shown in the figure) for decoration or marking is also provided between the outer surface of the housing 1 and the hydrophobic film 5.

[0045] In some embodiments, a support pad 10 is provided at each corner of the bottom outer surface of the housing 1. By providing the support pad 10, the housing 1 can be provided with a certain degree of support.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model and do not limit the utility model to the specific implementations described. Obviously, other modifications and variations can be made based on the content of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
