Description

Technical Field

[0001] This utility model relates to the field of packaging cartons, and in particular to packaging cartons that can be quickly assembled and folded. Background Technology

[0002] Cardboard boxes, as a common logistics and product packaging container, are widely used in various industries due to their low cost, ease of processing, and good cushioning and protection properties. To further improve ease of use and production efficiency, various types of packaging boxes that can be quickly assembled and bent into one piece have appeared on the market.

[0003] Currently, these one-piece molded packaging cartons are typically die-cut from a single piece of cardboard and bent using pre-crease lines to quickly form a complete box with a bottom, side panels, and a lid. This structure eliminates complex splicing and gluing steps, greatly improving packaging efficiency.

[0004] However, existing one-piece bent cardboard boxes also have a significant drawback: their interior is typically a single, undivided storage cavity. When multiple small items need to be transported or stored simultaneously, they are prone to collision and compression within the box, leading to damage or disarray. To achieve internal partitioning, separate dividers or partitions usually need to be manufactured and installed separately. This not only increases material costs and production steps but also makes the assembly process of the entire packaging structure cumbersome, contradicting the original intention of rapid assembly. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a packaging carton that can be quickly assembled and folded, which can effectively solve the technical problem of needing to produce and install separate partitions to separate storage compartments.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A quick-assembly and foldable packaging carton includes a carton body, which comprises an integrally bent bottom plate, side plates, and a cover plate. The side plates include a front side plate, a rear side plate, a left side plate, and a right side plate, which are located around the bottom plate. The cover plate is connected to the rear side plate at the end away from the bottom plate. The front side plate, rear side plate, left side plate, and right side plate are bent toward the bottom plate to form an upward-facing storage cavity. The cover plate covers the opening of the storage cavity after bending. One end of the left side plate and the right side plate is bent to form a positioning plate. The positioning plate is bent toward the storage cavity. The end of the positioning plate away from the side plate is bent to form a partition plate. The end of the partition plate away from the positioning plate is provided with a positioning block. The side plate opposite to the positioning plate is provided with a positioning hole corresponding to the positioning block. The partition plate divides the storage cavity into two or more receiving areas.

[0008] Furthermore, the left and right side plates are provided with fixed side plates that bend toward the bottom plate at the ends away from the bottom plate. After bending, the fixed side plates are parallel to the left and right side plates and form positioning slots. Positioning blocks are provided on the edges of the fixed side plates, and corresponding positioning holes are provided on the bottom plate. Positioning parts are provided at both ends of the front and rear side plates. After bending, the positioning parts are inserted into the positioning slots.

[0009] Furthermore, the end of the cover plate away from the rear side plate is bent to form a front baffle, and the two ends of the front baffle are bent to form fixing inserts, which are paired and inserted into positioning slots.

[0010] Furthermore, the side plate of the partition plate is bent with a reinforcing plate. The reinforcing plate has the same size as the partition plate and is attached to the partition plate after bending. The reinforcing plate is provided with a positioning block on the side facing the bottom plate, and the bottom plate is provided with a corresponding positioning hole.

[0011] Furthermore, the two ends of the cover plate are bent to form a cover insertion plate. When the cover plate closes the storage cavity, the cover insertion plate is inserted into the storage cavity and fits against the side plate of the storage cavity.

[0012] Compared with existing technologies, the advantages of this invention are: while maintaining the advantages of integrated bending and rapid folding of packaging cartons, it achieves internal space division of the storage cavity. Through positioning plates and partition plates extending from the integrated bending of the side panels, and with positioning blocks at the ends of the partition plates that cooperate with positioning holes on the opposite side panels, the partition plates can be installed synchronously and stably during the box assembly process, dividing a single storage cavity into two or more independent storage areas. This partition structure requires no additional independent parts, being completely integrally bent and formed with the box body. This avoids the cost and hassle of additional production and installation of partition plates, while ensuring the overall structural strength and ease of assembly of the packaging. It effectively solves the problem of mixed placement of items inside the box, making it highly practical. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] The following is combined with Figures 1-2 A detailed description of the quick-assembly and foldable packaging carton of this utility model is provided below:

[0018] A quick-assembly and foldable packaging carton includes a carton body, which includes an integrally bent bottom plate 1, side plates, and a cover plate 6. The side plates include a front side plate 2, a rear side plate 3, a left side plate 4, and a right side plate 5. The front side plate 2, rear side plate 3, left side plate 4, and right side plate 5 are located around the bottom plate 1. The cover plate 6 is connected to the end of the rear side plate 3 away from the bottom plate 1. The front side plate 2, rear side plate 3, left side plate 4, and right side plate 5 are bent toward the bottom plate 1 to form an upward-facing storage cavity. The cover plate 6 is bent to cover the opening of the storage cavity. One end of the left side plate 4 and right side plate 5 is bent to form a positioning plate 7. The positioning plate 7 is bent toward the storage cavity. The end of the positioning plate 7 away from the side plate is bent to form a partition plate 8. The end of the partition plate 8 away from the positioning plate 7 is provided with a positioning insert 16. The side plate opposite to the positioning plate 7 is provided with a positioning hole 17 corresponding to the positioning insert 16. The partition plate 8 divides the storage cavity into two or more receiving areas 9.

[0019] While retaining the advantages of integrated bending and rapid folding of the packaging carton, this design achieves internal space division within the storage cavity. Through positioning plates 7 and partition plates 8 extending from the integrated bending of the side panels, and with positioning inserts 16 at the ends of partition plates 8 that engage with positioning holes 17 on the opposite side panels, the partition plates 8 can be installed synchronously and securely during carton assembly, dividing the single storage cavity into two or more independent compartments 9. This partition structure requires no additional independent components, being completely integrated with the carton body through bending. This avoids the cost and hassle of additional production and installation of partition plates 8, while ensuring the overall structural strength and ease of assembly of the packaging. It effectively solves the problem of mixed storage of items inside the carton, making it highly practical.

[0020] The left side panel 4 and right side panel 5 have fixed side panels 10 that bend towards the bottom plate 1 at their ends away from the bottom plate 1. After bending, the fixed side panels 10 are parallel to the left side panel 4 and right side panel 5, forming positioning slots 18. Positioning inserts 16 are provided on the edges of the fixed side panels 10, and corresponding positioning holes 17 are provided on the bottom plate 1. Positioning parts 11 are provided at both ends of the front side panel 2 and rear side panel 3. After bending, the positioning parts 11 are inserted into the positioning slots 18. By providing bendable fixed side panels 10 on the left side panel 4 and right side panel 5 and engaging them with the positioning parts 11 on the front and rear side panels 3, the structural rigidity and overall stability of the four corners of the box are greatly enhanced. This slot-type connection method tightly locks the four side panels together, forming a sturdy frame that can effectively resist external compression and impact, preventing the box from deforming or falling apart during transportation.

[0021] The end of the cover plate 6 away from the rear side panel 3 is bent to form a front baffle 12. Both ends of the front baffle 12 are bent to form fixing inserts 13. The fixing inserts 13 are paired and inserted into the positioning slots 18. When the cover plate 6 is closed, the front baffle 12 and the fixing inserts 13 can be inserted into the positioning slots 18 on both sides of the box. This achieves a multi-point, stable connection between the cover plate 6 and the box, making the closed state more secure and effectively preventing the cover plate 6 from popping open due to accidental impact or vibration. It also enhances the overall integrity and aesthetics of the front of the box by 90 degrees, improving the protection level of the packaging.

[0022] The two ends of the cover plate 6 are bent to form closing inserts 14. When the cover plate 6 closes the storage cavity, the closing inserts 14 are inserted into the storage cavity and fit against the side plate of the storage cavity, adding two lateral support points to the cover plate 6, restricting its left and right movement, and making the closing structure more stable. In addition, this structure also improves the anti-theft and anti-accidental opening performance of the packaging box to a certain extent.

[0023] The side panels of the partition plate 8 are bent with reinforcing plates 15. The reinforcing plates 15 are the same size as the partition plate 8 and fit snugly against the partition plate 8 after bending. A positioning block 16 is provided on the side of the reinforcing plate 15 facing the bottom plate 1, and the bottom plate 1 is provided with a corresponding positioning hole 17. This significantly increases the thickness and bending strength of the partition plate 8, enabling it to better withstand the lateral pressure from the items in the two side receiving areas 9, preventing the partition plate 8 from bending or being damaged in the middle, and ensuring the long-term effectiveness of the partitioning effect. At the same time, fixing the bottom of the partition plate 8 to the bottom plate 1 further improves the stability of the entire internal support structure.

[0024] This embodiment provides a packaging carton that can be quickly assembled and folded. The carton is integrally formed from a single sheet of corrugated cardboard through die-cutting and creasing processes. When unfolded, it forms a flat, plate-like structure, facilitating transportation and storage.

[0025] Basic structure of the box: The packaging carton includes a box body. The core of the box body is a rectangular base plate 1. On the four sides of the base plate 1, a front side plate 2, a rear side plate 3, a left side plate 4, and a right side plate 5 are connected in sequence by pre-pressed bending lines. At the end of the rear side plate 3 away from the base plate 1, a cover plate 6 is connected by a bending line.

[0026] Side panel fixing and reinforcement structure: To achieve a more stable box structure, fixed side panels 10 are integrally bent at the ends of the left side panel 4 and right side panel 5 away from the bottom plate 1. During assembly, the fixed side panel 10 is bent 90 degrees toward the bottom plate 1, so that it is parallel to and tightly attached to the inner wall of the side panel, thereby forming a vertical positioning slot 18 between the two.

[0027] Meanwhile, flexible positioning parts 11 are provided at both ends of the front side panel 2 and the rear side panel 3. When all the side panels are erected and closed, the positioning parts 11 at both ends of the front side panel 2 and the rear side panel 3 are bent inward by 90 degrees and inserted precisely into the positioning slots 18 formed on the left and right sides. This structure, through mechanical interlocking, tightly connects the four side panels into a sturdy rectangular frame, significantly enhancing the pressure resistance of the corners of the box.

[0028] Internal space partitioning structure: To achieve internal partitioning, positioning plates 7 are integrally bent at one end of the left side plate 4 and the right side plate 5 via a bending line. The positioning plates 7 are bent toward the inside of the storage cavity. At the free end of each positioning plate 7, a partition plate 8 is formed by bending.

[0029] To further strengthen the partition plate 8, a reinforcing plate 15 of the same size is connected to its side. During assembly, the reinforcing plate 15 is first bent towards the partition plate 8 and fully fitted to it, thereby forming a thickened composite plate structure. A positioning block 16 is provided at the free end of this composite plate. Correspondingly, a positioning hole 17 is provided on the side plate opposite to this positioning block 16. In addition, a positioning block 16 is also provided on the lower edge of the reinforcing plate 15, and a matching positioning hole 17 is also provided at the corresponding position on the base plate 1.

[0030] The assembly process is as follows: After erecting the side panel, first bend the positioning plate 7 and the partition plate 8 with the reinforcing plate 15. Insert the positioning block 16 at the free end of the partition plate 8 into the positioning hole 17 of the opposite side panel, and at the same time insert the positioning block 16 at the bottom of the partition plate 8 into the positioning hole 17 of the base plate 1. In this way, the partition plate 8 is fixed in both its height direction and bottom, resulting in an extremely stable structure that effectively divides the storage cavity into multiple independent storage areas 9.

[0031] The cover plate 6 has a closing structure: at the end of the cover plate 6 away from the rear side plate 3, a front baffle 12 is formed by bending. At both ends of the front baffle 12, fixing inserts 13 are formed by bending. In addition, closing inserts 14 are formed by bending on both sides of the cover plate 6. When it is necessary to close the packaging box, the cover plate 6 is bent downwards to cover the opening of the storage cavity.

[0032] During this process: the cover plates 14 on both sides of the cover plate 6 will be inserted downward into the storage cavity and closely adhere to the inner wall of the side plate. The front baffle 12 at the front end of the cover plate 6 will then be fastened to the outside of the front side plate 2, while the fixing plates 13 at both ends will be precisely inserted into the positioning slots 18 formed by the fixing side plate 10, the left side plate 4, and the right side plate 5.

[0033] 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.
