Description

Technical Field

[0001] This utility model relates to the field of paper packaging box technology, and in particular to a multi-sided snap-lock foldable paper packaging box. Background Technology

[0002] In the current paper packaging box industry, common box structures are relatively simple, mostly assembled using simple folding and gluing methods. For example, some paper packaging boxes are simply folded into box shape using simple creases, and then the edges are fixed with glue or tape. This assembly method is not only cumbersome, but also prone to deformation and falling apart during transportation and storage due to the lack of effective connecting and restraining structures, resulting in poor stability and sturdiness of the packaging box.

[0003] Furthermore, while some paper packaging boxes possess certain connecting structures, their complex structures result in high production costs, and the assembly process requires specialized tools or complex procedures, hindering large-scale production and practical application. Simultaneously, existing paper packaging boxes also fall short in terms of reusability and foldable storage, failing to meet the demands of modern logistics and packaging industries for environmental protection, convenience, and efficiency. Therefore, developing a simple, easy-to-assemble, stable, and foldable paper packaging box is of significant practical importance. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing assembly method, which is not only cumbersome to operate, but also complex in structure and high in manufacturing cost due to the lack of effective connection and limiting structure during transportation and storage. Furthermore, the assembly process requires professional tools or complicated operating steps, which is not conducive to large-scale production and practical application. Therefore, this utility model proposes a multi-sided snap-lock interlocking foldable paper packaging box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-sided snap-lock interlocking foldable paper packaging box includes a bottom paper shell and a top cardboard. The top of the bottom paper shell is integrally formed with multiple bendable outer cardboards, which cooperate to form a polygon. The top cardboard is snapped onto the multiple outer cardboards. Two first bent cardboards are integrally formed on one side of the outer cardboards. The interior of the first bent cardboards has a strip-shaped hole, and the interior of the multiple first bent cardboards is provided with the same connecting component for connecting the outer cardboards. The top of the bottom cardboard shell is provided with a limiting component for limiting the outer cardboard and the bottom cardboard shell.

[0006] In one possible design, the connecting assembly includes multiple internal reinforcing cardboards connected end to end, one of the internal reinforcing cardboards having a break in the middle, and the top and bottom of the internal reinforcing cardboards being integrally formed with foldable extension cardboards, the internal reinforcing cardboards being used in conjunction with strip holes.

[0007] In one possible design, one side of the lower extension cardboard is integrally formed with a foldable second bent cardboard, the interior of which has a second insertion hole.

[0008] In one possible design, the limiting component includes a pressure plate, the bottom of which is integrally formed with a plurality of first connecting cardboards, the interior of which has a plurality of first insertion holes, and the bottom of which has an annular groove, wherein the first insertion holes and the second insertion holes are used in conjunction with the first connecting cardboards.

[0009] In one possible design, one end of the first connecting cardboard is integrally formed with a foldable insert cardboard, and the inner wall of the annular groove is provided with a plurality of insert slots, which engage with the insert cardboard, and the size of the insert slot is larger than the size of the insert cardboard.

[0010] In one possible design, the outer wall of the pressure plate has multiple rectangular holes that engage with two adjacent first bending cardboard pieces.

[0011] In this application, during use, multiple outer cardboard pieces are bent inward from the side of the bottom cardboard shell, forming a polygon. The multiple first-bent cardboard pieces on the sides of the outer cardboard pieces are then joined together, and multiple slotted holes are connected. The second-bent cardboard piece and the extension cardboard piece are folded towards the side of the inner reinforcing cardboard piece. The entire inner reinforcing cardboard piece is then inserted through the multiple slotted holes. Because the inner reinforcing cardboard piece has a break, one end of the piece can be inserted and then exit through the last slotted hole, allowing the multiple outer cardboard pieces to be connected together. The extension cardboard piece and the second-bent cardboard piece can then be folded outward and wedged between the multiple first-bent cardboard pieces. The inner reinforcing cardboard piece cannot be directly pulled out, thus improving the stability of the device. The second insertion hole is aligned with the first insertion hole. The pressure plate is pressed onto the top of the bottom cardboard shell, and the first connecting cardboard piece and the insert cardboard piece are inserted through the first and second insertion holes into the annular groove. The insert cardboard piece is then bent, with one end inserted into the insertion groove. The insertion groove is larger than the insert cardboard piece for easy insertion. Finally, the top cardboard piece is closed, completing the assembly of the box.

[0012] Beneficial Effects: This multi-sided, interlocking, foldable paper packaging box is easy to assemble. Simply bend multiple outer cardboard pieces from the sides of the bottom shell inwards to form a polygon. At this point, the multiple first-folded cardboard pieces on the sides of the outer cardboard pieces fit together, and the multiple slotted holes are connected. Next, insert the inner reinforcing cardboard through the slotted holes, and then fold the extension cardboard and second-folded cardboard outwards to lock them between the first-folded cardboard pieces, thus completing the connection of the outer cardboard pieces. Then, press the pressure plate onto the top of the bottom shell, and insert the first connecting cardboard and the insert cardboard through the first and second insertion holes into the annular groove. The insert cardboard is then bent and inserted into the insertion slot. Finally, the top cardboard is placed on top. The entire assembly process is simple and quick, requiring no professional tools or complex operations, greatly improving assembly efficiency.

[0013] Multiple outer cardboard sheets are connected together by an internal reinforcing cardboard, which has a slit, allowing one end to pass through the last slot after insertion. Simultaneously, the extension cardboard and the second folded cardboard are folded outwards and secured between the multiple first folded cardboard sheets, effectively preventing the internal reinforcing cardboard from being pulled out directly and enhancing the connection stability between the outer cardboard sheets. Furthermore, the pressure plate is fixed to the bottom cardboard shell by the first connecting cardboard and the insert cardboard, further improving the structural stability of the entire packaging box and preventing deformation or scattering during transportation and storage.

[0014] This paper packaging box features a foldable design. When not in use, the outer cardboard, the first fold cardboard, the extended cardboard, and the second fold cardboard can all be folded, significantly reducing the space occupied by the box and facilitating transportation and storage. This foldable feature also aligns with environmental protection principles, promoting the rational use and recycling of resources.

[0015] The bottom of the pressure plate in the limiting assembly is integrally formed with multiple first connecting cardboard pieces. Multiple first insertion holes are formed inside the bottom cardboard shell, and an annular groove is formed at the bottom of the bottom cardboard shell. One end of each first connecting cardboard piece is integrally formed with a foldable insert cardboard piece, and multiple insertion slots are formed on the inner wall of the annular groove. During assembly, the first connecting cardboard pieces and the insert cardboard pieces pass through the first and second insertion holes into the annular groove. The insert cardboard pieces are bent and inserted into the insertion slots, and the size of the insertion slots is larger than the size of the insert cardboard pieces. This design makes the limiting more precise and reliable, effectively preventing the pressure plate from loosening or shifting, and ensuring the overall structural stability of the packaging box.

[0016] Multiple rectangular holes on the outer wall of the pressure plate engage with the two adjacent first-fold cardboard sections. This design ensures a tighter connection between the pressure plate and the outer cardboard, further enhancing the adaptability and stability of the packaging box. Simultaneously, this engagement method facilitates assembly and disassembly, improving the practicality and flexibility of the packaging box. Attached Figure Description

Multiple first insertion holes 6 are opened inside the bottom cardboard shell 1. An annular groove 5 is opened on the bottom of the bottom cardboard shell 1. The first insertion holes 6 and second insertion holes 12 are used in conjunction with the first connecting cardboards 9. A foldable insert cardboard 4 is integrally formed on one end of the first connecting cardboard 9. The insert cardboard 4 is made of paper. Multiple insertion slots 10 are opened on the inner wall of the annular groove 5. The insertion slots 10 engage with the insert cardboard 4. The size of the insertion slots 10 is larger than the size of the insert cardboard 4 to facilitate the insertion of the insert cardboard 4. After the outer cardboard 2 is connected, the pressure plate 7 is pressed on the top of the bottom cardboard 1, and the first connecting cardboard 9 and the insert cardboard 4 are passed through the first insertion hole 6 and the second insertion hole 12 into the interior of the annular groove 5. Then the insert cardboard 4 is bent and one end of the insert cardboard 4 is inserted into the interior of the insertion groove 10 to limit the outer cardboard 2 and the bottom cardboard 1.

[0023] This multi-faceted, interlocking, foldable paper packaging box has a simple structure and is easy to assemble. Through internal reinforcing cardboard 8 and pressure plate 7, it effectively connects and limits the box, improving its stability and robustness, and preventing deformation or scattering during transportation and storage. Furthermore, the box is foldable; when not in use, the outer cardboard 2, first-bend cardboard 11, extension cardboard 14, and second-bend cardboard 15 can all be folded, significantly reducing the space occupied by the box, facilitating transportation and storage, meeting the requirements of environmental protection, convenience, and efficiency, and is conducive to large-scale production and practical application.
