Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to a modular cardboard box structure with auxiliary nesting components. Background Technology

[0002] Cardboard boxes are widely used as a common packaging and storage container in warehousing, logistics, display, and tool storage. To categorize, secure, or cushion the items inside, internal partitions, supports, and other nesting components are typically required. Current technologies commonly employ pre-fabricated foam linings, cardboard dividers secured with tape, or fixed-size plastic dividers.

[0003] However, these existing solutions have significant limitations. For example, prefabricated foam linings or fixed-size dividers have a fixed internal structure, which cannot be flexibly adjusted according to the actual size and shape of the items, resulting in low space utilization or inability to accommodate items of different sizes. While using tape to temporarily fix cardboard partitions offers some flexibility, it is cumbersome and time-consuming, and the tape is difficult to remove and reuse without damage after application. Furthermore, the connection strength is often insufficient, making them prone to shifting or falling off during transportation. In addition, these solutions typically lack the ability to quickly reconfigure the internal layout, making it difficult to meet the needs of scenarios requiring frequent changes to stored or displayed content. Utility Model Content

[0004] The main technical problem this utility model addresses is how to provide a modular cardboard box structure with a flexible and quick internal space layout and a strong connection, so as to overcome the defects of existing technologies where nested components are fixed, inconvenient to adjust, or have unstable connections.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a modular cardboard box structure with auxiliary nesting components, including a modular cardboard box body and at least one auxiliary nesting component. The auxiliary nesting component consists of multiple standardized panels, each made of a lightweight, rigid material, with flexible magnetic strips embedded in its edges or interior. Magnetic strips are embedded in the inner wall of the modular cardboard box body at predetermined vertical strip positions. These magnetic strips are magnetically attracted to the flexible magnetic strips on the panels, allowing the panels to be detachably fixed to any of the vertical strip positions on the inner wall of the modular cardboard box body via magnetic adsorption, thereby forming different internal compartments or layered structures.

[0006] Preferably, the lightweight rigid material is polypropylene plastic or high-grammage cardboard.

[0007] Preferably, the edge of the panel is provided with a covering layer, and the flexible magnetic strip is embedded in the covering layer.

[0008] Preferably, the magnetic strip is an ferrous metal strip or a magnetic strip with the opposite polarity to the flexible magnetic strip.

[0009] Preferably, the panel is also provided with a standard interface, which is a slot or a protrusion structure, to enable adjacent panels to be spliced ​​together to build a more complex three-dimensional support structure.

[0010] Preferably, the inner wall of the modular carton body is provided with visual markings for indicating the position of the vertical stripes.

[0011] The beneficial effects of this invention are as follows: Due to the structure of the panel with embedded flexible magnetic strips cooperating with the magnetic strips on the inner wall of the box, users can quickly and easily attach the panel to any preset position inside the box according to the size and shape of the items, achieving instant and flexible reconstruction of the internal space layout. This magnetic connection method requires no tools or adhesives, is easy to assemble and disassemble, and provides a firm and reliable connection, preventing displacement during transportation. At the same time, the standardized panel design facilitates production, management, and system expansion, and can adapt to boxes of various sizes, significantly improving the adaptability and ease of use of the cardboard box in warehousing, display, and storage scenarios.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0018] Please see Figures 1 to 4 This utility model provides a modular cardboard box structure with auxiliary nesting components. The structure mainly includes a modular cardboard box body 1 and at least one auxiliary nesting component 2.

[0019] The modular carton body 1 has a conventional rectangular box structure, made of corrugated cardboard or other rigid cardboard through folding and gluing. Its key improvement lies in the structure of the inner wall 11. During manufacturing, multiple magnetic strips 12 are embedded at predetermined positions on the inner wall 11. These magnetic strips 12 are arranged to form a regular vertical stripe array 13. To facilitate user positioning, visual markings 14 corresponding to the vertical stripe array 13, such as crosshairs or dots, can be printed or embossed on the inner wall 11. In this embodiment, the magnetic strips 12 are preferably ferrous metal strips, which are fixed to the cardboard interlayer of the inner wall 11 by adhesive or hot pressing. In other alternative embodiments, the magnetic strips 12 can also be magnetic strips with opposite polarity to the magnetic strips on the auxiliary nesting assembly 2.

[0020] The auxiliary nesting assembly 2 consists of multiple standardized panels 21. Each panel 21 includes a lightweight rigid substrate 211. The substrate 211 can be made of polypropylene (PP) plastic, high-density polyethylene (HDPE), or cardboard to ensure that the panel 21 has sufficient supporting strength while being lightweight. A covering layer 213 is provided at the edge of the lightweight rigid substrate 211, which can be made of plastic or rubber. One or more flexible magnetic strips 212 are pre-embedded in the covering layer 213. The magnetic poles of the flexible magnetic strips 212 are aligned to ensure that they can generate sufficient attraction force with the iron magnetic strips 12 on the inner wall 11 of the housing.

[0021] In addition, to construct more complex three-dimensional structures, standard interfaces are designed on panel 21. These standard interfaces can be slots 214 formed on one edge of panel 21 and protrusions 215 formed on the opposite edge. The dimensions of the protrusions 215 match the dimensions of the slots 214, allowing the protrusions 215 of one panel 21 to be inserted into the slots 214 of another panel 21, thereby achieving mechanical splicing and angle fixation between the two panels 21.

[0022] Working Principle and Assembly Process: The working principle of this utility model is based on magnetic adsorption and mechanical splicing. When the user needs to configure the internal layout of the modular carton body 1, the working process is as follows: 1. Layout planning: Users plan the required compartments or layered structures based on the size and shape of the items to be stored.

[0023] 2. Panel Selection and Fixing: The user selects the required number and type of panels 21. The side of panel 21 with the flexible magnetic strip 212 is placed close to the selected vertical strip 13 position on the inner wall 11 of the enclosure. Due to magnetic force, the panel 21 will be quickly and firmly attracted to the magnetic strip 12. By attracting multiple panels 21 at different positions on the vertical strip 13, basic structures such as horizontal partitions, vertical partitions, or L-shaped brackets can be quickly formed.

[0024] 3. Assembling Complex Structures: For support structures requiring higher strength or more complex shapes, the user can align the protrusions 215 of one panel 21 and insert it into the slots 214 of another panel 21. Through this insertion method, multiple panels 21 can be interconnected to form a stable three-dimensional frame, such as... Figure 4 As shown.

[0025] 4. Adjustment and Reassembly: When a layout change is required, the user simply needs to overcome the magnetic force to remove panel 21 from the inner wall 11, or disconnect the panels 21 from each other, and then reattach and reassemble them according to the new plan. The entire process requires no tools, tape, or other consumables.

[0026] As can be seen from the above specific embodiments, this invention achieves rapid, flexible, and robust reconfigurability of the internal structure of the carton by combining magnetic adsorption with standard interface splicing. Magnetic adsorption provides a convenient and reversible fixing method between the panel 21 and the carton body, while mechanical insertion enhances the overall rigidity and load-bearing capacity of the combined structure between the panels 21. The standardized design makes the system easy to manufacture and expand, and can be widely adapted to various scenarios that require frequent adjustments to the internal space, such as logistics sorting, retail display, and tool and equipment storage.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications and variations. For example, the shape of the panel 21 is not limited to a rectangle, but can also be triangular, trapezoidal, etc.; the standard interface can also be in the form of hooks and slots, Velcro, etc. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
