Description

Technical Field

[0001] This utility model relates to the field of cardboard box structure technology, and in particular to an embedded one-piece molded cardboard box structure. Background Technology

[0002] In the field of modern logistics and commodity packaging, cardboard boxes are one of the most widely used packaging containers. Their design goals have always revolved around reducing production costs, improving assembly efficiency, enhancing protective performance, and meeting environmental protection requirements. Traditional cardboard boxes are usually composed of multiple parts such as bottom cardboard, side cardboard, and lid. During production, they need to be glued or nailed together. The assembly process relies on manual operation, which is inefficient and prone to instability due to glue overflow or loose nails. Although some improved cardboard boxes adopt a folding design to reduce splicing steps, the top closure still requires additional tape or locks, which not only increases material costs but also affects recycling due to tape residue or lost locks. In addition, the surface of traditional cardboard boxes is mostly smooth, which can easily lead to slippage and drop during handling. Furthermore, they lack convenient classification labeling design, requiring additional labels in logistics and warehousing scenarios, which affects information identification efficiency.

[0003] Chinese patent discloses a high-strength cardboard box (publication number: CN 213677591 U) including a cardboard box body. The cardboard box body includes a bottom plate, four side plates disposed on the bottom plate, and a cover plate disposed on the side plates. The bottom plate, side plates, and cover plate are integrally formed. A support column is provided between every two adjacent side plates. The cross-section of the support column is triangular. A reinforcing structure is provided on the bottom plate. The reinforcing structure includes a support tray, a support top plate, and multiple support plates. Cavities are provided in the side plates and the cover plate. However, this cardboard box has problems such as low production and assembly efficiency, insufficient environmental protection and stability, poor handling safety, and lack of classification management function. Therefore, an embedded integrally formed cardboard box structure is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low production and assembly efficiency, insufficient environmental protection and stability, poor handling safety and lack of classification and management functions of traditional cardboard boxes in the prior art, and to propose an embedded one-piece molded cardboard box structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The embedded one-piece molded carton structure of this utility model includes an integrally molded carton body. The carton body is characterized by being made of foldable molding material, comprising a bottom support plate, and four side panels surrounding the bottom support plate. Embedded snap-fit ​​structures are provided on the top perimeter of the four side panels, connecting end-to-end to form a closed carton body. The embedded snap-fit ​​structures are pre-formed along the fold lines of the carton body. This structure, through its one-piece molding design, eliminates the need for multi-part assembly during carton manufacturing, simplifying the production process and improving efficiency. The embedded snap-fit ​​structure design eliminates the need for glue or nails during assembly, allowing for secure closure through its own structure, thus improving assembly convenience and environmental friendliness. The pre-formed fold lines make the snap-fit ​​structure more accurate and stable during folding, enhancing the overall structural strength and reliability of the carton body.

[0006] Preferably, the connection between the bottom support plate and the four side wall panels is provided with pre-formed creases. The side wall panels can be folded vertically along the pre-formed creases 90°-180° relative to the bottom support plate to form an upright box. The design of the pre-formed creases allows the side wall panels to be folded quickly at a predetermined angle, which is convenient for flat laying during transportation and storage, and also supports rapid unfolding to form an upright box, adapting to various usage scenarios.

[0007] Preferably, the embedded snap-fit ​​structure includes a first side plate and a second side plate, with two of each side plate corresponding to each other. The first side plate has a snap-fit ​​tongue, and the second side plate has a snap-fit ​​slot. The snap-fit ​​tongue and the snap-fit ​​slot cooperate with each other. Through the embedded cooperation design of the tongue and slot, a stable closure of the snap-fit ​​structure at the top of the box is achieved. Assembly can be completed without external tools or fasteners, making the operation simple and quick. This structural design enhances the sealing and overall stability of the box, preventing accidental opening during transportation or stacking, and improving the safety and reliability of the packaging.

[0008] Preferably, the top edges of the four side panels of the box are provided with embedded handle grooves, and the inner walls of the embedded handle grooves are provided with anti-slip textures. The embedded handle groove design allows users to directly lift the box using its own structure when carrying it, without the need for additional handle components, simplifying the design and reducing costs; the anti-slip textures enhance the friction between the hand and the handle groove, making the lifting process more stable and improving the comfort and safety of handling, especially suitable for scenarios requiring frequent handling.

[0009] Preferably, one side of each of the four side panels of the container is provided with an index label slot, which is transparent. The index label slot allows users to easily insert labels from the outside of the container, facilitating the classification, identification, and management of items inside. This is particularly suitable for scenarios requiring rapid content identification, such as logistics and warehousing. The transparent design makes the label content clearly visible, allowing information to be obtained without opening the container, thus improving the efficiency and accuracy of information retrieval.

[0010] Preferably, the box body is made of three-layer corrugated paper composite board, with a water-based ink-printed anti-slip textured layer on its surface. The use of three-layer corrugated paper composite board gives the box body excellent pressure resistance, impact resistance, and cushioning performance, effectively protecting the items inside from external pressure and vibration. The water-based ink-printed anti-slip textured layer not only meets environmental protection requirements but also enhances the friction of the box surface, preventing slippage during handling or stacking, thus improving safety and stability. Furthermore, the use of environmentally friendly materials aligns with the modern packaging industry's requirements for sustainable development.

[0011] The advantages of this utility model are:

[0012] This application's embedded one-piece molded cardboard box structure integrates the bottom support plate and four side panels into a single sheet material through an integrated folding material design. Pre-formed creases enable rapid folding and unfolding, significantly simplifying the production and assembly process of traditional cardboard boxes that require multiple parts. The embedded snap-fit ​​structure at the top of the box connects end-to-end through the snap-fit ​​tongue of the first side panel and the snap-fit ​​slot of the second side panel, forming a nail-free closure. This avoids environmental pollution and cumbersome operation associated with auxiliary fasteners while ensuring structural stability during transportation and stacking. Embedded handle grooves on the top edges of the four side panels, combined with anti-slip textured inner walls, allow users to directly utilize the box's structure for handling, improving operational comfort and safety. Transparent index label slots on one side of each side panel support quick insertion of classification labels, facilitating information identification and management in logistics and warehousing scenarios. The box is made of three-layer corrugated paper composite board, with a water-based ink-printed anti-slip textured layer on the surface. This enhances pressure and impact resistance while meeting environmental protection requirements and further improving surface friction to prevent slippage. The overall structure achieves a unified balance of efficiency, environmental friendliness, and functionality throughout the entire process from production and assembly to use, making it particularly suitable for scenarios requiring rapid packaging, convenient handling, and information management, such as e-commerce logistics, fast-moving consumer goods packaging, and display packaging.

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 scope of protection of the present utility model. Example

[0021] Please see Figure 1-5As shown, an embedded one-piece molded carton structure includes a one-piece molded carton body 1. The carton body 1 is characterized by being constructed from a foldable molding material, comprising a bottom support plate 3, and four side panels 2 surrounding the bottom support plate 3. Embedded snap-fit ​​structures are provided around the top perimeter of each side panel 2, connecting end-to-end to form a closed carton body 1. These embedded snap-fit ​​structures are pre-formed along the fold lines of the carton body 1. This structure, through its one-piece molding design, eliminates the need for multi-part assembly during carton manufacturing, simplifying the production process and improving efficiency. The embedded snap-fit ​​structure design allows the carton body 1 to close securely without the need for glue or nails during assembly, enhancing assembly convenience and environmental friendliness. The pre-formed fold lines make the snap-fit ​​structure more accurate and stable during folding, strengthening the overall structural strength and reliability of the carton body 1.

[0022] In this embodiment, pre-formed creases are provided at the connection between the bottom support plate 3 and the four side wall panels 2. The side wall panels can be folded vertically along the pre-formed creases 90°-180° relative to the bottom support plate 3 to form an upright box 1. The design of the pre-formed creases allows the side wall panels to be folded quickly at a predetermined angle, which is convenient for flat laying during transportation and storage, and also supports rapid unfolding to form an upright box 1, adapting to various usage scenarios.

[0023] In this embodiment, the embedded snap-fit ​​structure includes a first side plate 4 and a second side plate 6, with two of each side plate 4 and two corresponding side plates 6. The first side plate 4 is provided with a snap-fit ​​tongue 5, and the second side plate 6 is provided with a snap-fit ​​slot 7. The snap-fit ​​tongue 5 and the snap-fit ​​slot 7 cooperate with each other. Through the embedded cooperation design of the tongue and slot, the top snap-fit ​​structure of the box 1 is securely closed, and assembly can be completed without external tools or fasteners, making the operation simple and quick. This structural design enhances the sealing and overall stability of the box 1, preventing accidental opening during transportation or stacking, and improving the safety and reliability of the packaging.

[0024] In this embodiment, the top edges of the four side wall panels 2 of the box body 1 are provided with embedded handle grooves 8, and the inner wall of the embedded handle grooves 8 is provided with anti-slip textures 9. The design of the embedded handle grooves 8 allows users to directly lift the box body 1 using its own structure when carrying it, without the need for additional handle components, simplifying the design and reducing costs; the anti-slip textures 9 enhance the friction between the hand and the handle groove, making the lifting process more stable, improving the comfort and safety of carrying, and is especially suitable for scenarios that require frequent carrying.

[0025] In this embodiment, one side of each of the four side panels 2 of the box 1 is provided with an index label slot 10, which is a transparent structure. The index label slot 10 allows users to easily insert labels from the outside of the box 1, facilitating the classification, identification, and management of items inside the box. This is particularly suitable for scenarios requiring rapid content identification, such as logistics and warehousing. The transparent structure makes the label content clearly visible, allowing information to be obtained without opening the box 1, thus improving the efficiency and accuracy of information retrieval.

[0026] In this embodiment, the material of the box body 1 is a three-layer corrugated paper composite board, and its surface is provided with a water-based ink printed anti-slip texture layer. The use of the three-layer corrugated paper composite board gives the box body 1 good pressure resistance, impact resistance and cushioning performance, which can effectively protect the items inside the box from the influence of external pressure and vibration; the water-based ink printed anti-slip texture layer not only meets environmental protection requirements, but also enhances the friction of the surface of the box body 1, preventing slippage during handling or stacking, and improving the safety and stability of use; at the same time, the use of environmentally friendly materials also meets the requirements of the modern packaging industry for sustainable development.

[0027] The implementation principle of this embodiment is as follows:

[0028] Folding and unfolding stage: The initial state of the carton is a flat folded material, with the bottom support plate 3 and the four side panels 2 connected by pre-formed creases. The user folds the four side panels 2 vertically along the creases by 90°-180°, so that the carton 1 unfolds from a flat state into an upright frame. At this time, the bottom support plate 3 naturally forms the bottom load-bearing surface of the carton 1, and the four side panels 2 enclose and form the sides of the carton 1.

[0029] Top Closing Stage: The unfolded cabinet 1 features an embedded snap-fit ​​structure around its top perimeter. This structure consists of snap-fit ​​tongues 5 on two first side panels 4 and snap-fit ​​slots 7 on two second side panels 6. The user inserts the tongues of the first side panels 4 into the slots of the adjacent second side panels 6. The snap-fit ​​between the tongues and slots achieves seamless connection of the four sides of the top, forming a gapless closure. During this process, the snap-fit ​​structure is positioned along the pre-set fold lines of the cabinet 1, ensuring precise alignment of the tongues and slots, allowing for a secure closure without additional adjustments.

[0030] Handling and labeling stage: After the box 1 is closed, the user can directly insert their hands into the embedded handle grooves 8 at the top of the four side wall panels 2 for handling. The anti-slip texture 9 on the inner wall increases the friction of the hands and prevents slippage. If classified management is required, the index label can be inserted into the transparent slot on one side of the side wall panel. The label content is clearly visible through the transparent structure, which makes it easy to quickly identify the information of the items in the box.

[0031] Structural stability guaranteed: The three-layer corrugated paper composite board provides physical support for the box body 1 to resist pressure and impact. The water-based ink printed anti-slip texture layer on the surface further enhances the surface friction and prevents the box body 1 from sliding during stacking or handling. The embedded design of the snap-fit ​​structure makes the top self-locking after closing, so it is not easy to open accidentally even if it is subjected to external impact, ensuring the safety of the items inside the box.
