Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a novel pressure-resistant packaging box. Background Technology

[0002] Packaging boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and there are various specifications and models. Cardboard boxes commonly have three or five layers, while seven layers are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while corrugated paper is used for the core paper. The color and feel of each type of paper are different, and the paper produced by different manufacturers also varies in color and feel.

[0003] During logistics transportation and goods storage, the compressive strength of packaging boxes directly affects the safety of the contents. Existing ordinary cardboard boxes or conventional packaging structures are prone to deformation, collapse, or bulging when subjected to external stacking or impact, resulting in damage to the contents.

[0004] While some reinforced packaging boxes exist, such as those that improve pressure resistance by incorporating a support frame or filling with cushioning materials, these methods often suffer from problems like complex structures, high production costs, inconvenient assembly, or poor environmental performance. For example, some support structures are not firmly integrated with the box body and are prone to displacement or failure under long-term pressure; other solutions increase packaging time and material costs due to the excessive number of components. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the background art mentioned above, and to provide a new type of pressure-resistant packaging box that is simple in structure, easy to assemble, has significant pressure resistance, and is cost-controllable.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a novel pressure-resistant packaging box, comprising a packaging box body, wherein an inner lining support is provided inside the packaging box body, the support plate of the inner lining support is close to the inner wall of the packaging box body, and an arched plate is provided on the top of the inner lining support, the arched plate comprising two inclined side wings and two opposing vertical surfaces, the support plate respectively supporting the two side wings, and inverted buckle plates that are inserted and fastened to the outside of the packaging box body are connected to the two vertical surfaces, thereby forming a pressure-resistant structure of internal support and external locking for the arched plate.

[0007] Furthermore, the inner lining support includes four support plates symmetrically attached to two opposite inner walls of the packaging box, with the bottom and side surfaces of the support plates respectively bonded to the inner bottom and inner wall surfaces of the packaging box.

[0008] Furthermore, the inner lining support also includes a base plate connected to the bottom of the support plate, and L-shaped reinforcing plates that fit into the four corners of the packaging box are connected to the four corners of the base plate. The L-shaped reinforcing plates are at the same height as the support plate.

[0009] Furthermore, the inverted buckle plate is T-shaped and includes a connecting part connected to the vertical surface. One end of the connecting part is connected to a buckle plate that is symmetrically arranged vertically. The buckle plate is J-shaped and its root is connected to the connecting part. The two buckle plates are spaced apart.

[0010] Furthermore, both sides of the packaging box have through openings, and the two buckle plates are inserted through the through openings and locked to the outside of the packaging box.

[0011] Furthermore, several reinforcing ribs are provided between the two side wings and the horizontal surface of the arched plate.

[0012] Furthermore, the top opening of the packaging box is connected to a lid, which is folded and sealed with adhesive tape. The two ends of the tape are respectively attached to the two sides of the packaging box, and the adhesive side of the tape covers and attaches the two buckle plates respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the combined design of the inner lining support and the arched plate, the top pressure is effectively distributed to the side walls and bottom of the box, avoiding stress concentration and greatly enhancing the overall pressure bearing capacity; the support plate, bottom plate and L-shaped reinforcing plate in the inner lining support form a three-dimensional support system, which enhances the stability of the box corners and side walls and prevents bulging or collapse; the arched plate forms a fixed mechanism that combines internal and external support through the through-locking method of the internal support and the external inverted plate, preventing component displacement and ensuring long-term structural reliability.

[0014] 2. The reinforcing ribs between the arched panel and the side wings further enhance the bending strength of the arched structure, making it less prone to deformation under heavy pressure. The sealing tape not only seals the box lid but also covers and secures the outer panels, providing secondary reinforcement and improving the overall structural integrity.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0019] Combination Figures 1 to 7 As shown, this utility model provides a novel pressure-resistant packaging box, including a packaging box body 1, an inner lining support 2, an arched plate 4, an inverted snap plate 7, and other main components. The packaging box body 1 is made of conventional cardboard or similar materials and has a rectangular box structure, including a bottom, side walls, and a top opening, with a foldable flip-top lid 12 on the top.

[0020] like Figure 2 As shown, in this embodiment, an inner lining support 2 is provided inside the packaging box 1. The inner lining support 2 includes four support plates 3, which are symmetrically attached to two opposite inner walls of the packaging box 1. The bottom and side surfaces of each support plate 3 are fixed to the inner bottom and inner wall surfaces of the packaging box 1 by adhesive bonding, thereby providing stable internal support.

[0021] like Figure 3-4 As shown, in another embodiment, the inner lining support 2 also includes a base plate 8 connected to the bottom of the support plate 3. L-shaped reinforcing plates 9 are connected to the four corners of the base plate 8. These L-shaped reinforcing plates 9 fit tightly against the four inner corners of the packaging box 1, and their height is consistent with that of the support plate 3. The L-shaped reinforcing plates 9 further enhance the structural strength of the corners of the packaging box 1, preventing deformation under pressure.

[0022] like Figure 4 and Figure 5 As shown, the top of the inner lining support 2 is supported by an arched plate 4. The arched plate 4 includes two inclined side wings 5 ​​and two opposing vertical surfaces 6. The support plate 3 supports the two side wings 5 ​​respectively, so that the arched plate 4 can evenly distribute the pressure from above. To enhance the rigidity of the arched plate 4, several reinforcing ribs 11 are provided between the two side wings 5 ​​and the horizontal surface of the arched plate 4. The reinforcing ribs 11 are provided by bonding or integral molding, which effectively improves the bending resistance of the arched plate 4.

[0023] like Figure 6 As shown, inverted snap plates 7 are connected to the two vertical surfaces 6 of the arched plate 4. The inverted snap plates 7 are T-shaped and include a connecting part 71 connected to the vertical surface 6. One end of the connecting part 71 is connected to a snap plate 72 that is symmetrically arranged vertically. The snap plates 72 are J-shaped and are connected to the connecting part 71 at their base. The two snap plates 72 are spaced apart.

[0024] Both sides of the packaging box 1 have through openings 10. During assembly, the assembler pinches the two snap plates 72 on the same side towards each other (i.e., clamps them horizontally towards the middle), then inserts the two snap plates 72 through the inside into the through openings 10, and then releases the two snap plates 72. At this time, the two snap plates 72 spring back to the upper and lower sides respectively, and lock onto the outside of the packaging box 1 (e.g., Figure 1 and Figure 7 (As shown). This design allows the arched panel 4 to be double-fixed by internal supports and external locking, forming a stable compression-resistant structure.

[0025] like Figure 7 As shown, the top opening of the packaging box 1 is sealed by folding and flipping the lid 12. After sealing, tape 13 is used to bond the lid 12 to the packaging box 1. The two ends of the tape 13 are respectively bonded to the two sides of the packaging box 1, and its adhesive surface covers and bonds the two snap-on plates 72. This not only achieves the sealing of the box, but also further fixes the snap-on plates 7, preventing them from loosening on the one hand, and strengthening the locking force on the arched plate 4 and the pressure resistance of the arched plate 4 on the other hand.

[0026] Working principle; First, the items are placed inside the packaging box 1. Then, the arched plate 4 is installed. This is achieved through the support of the inner lining support 2 and the through-locking of the outer inverted plate 7, forming a combined internal and external fixing mechanism. When the packaging box is subjected to external pressure, the arched plate 4 transmits the pressure to the inner lining support 2 via the side wings 5. The inner lining support 2 then distributes the pressure to the box walls and corners via the support plate 3 and L-shaped reinforcing plate 9. Simultaneously, the inverted plate 7 is locked to the outside of the box through the through-hole 10, preventing the arched plate 4 from shifting or warping. The reinforcing rib 11 enhances the load-bearing capacity of the arched plate 4, while the adhesive tape 13 ensures the long-term stability of the inverted plate 7. The entire structure works synergistically, significantly improving the packaging box's pressure resistance and overall reliability.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
