[0036] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0037] As described in the background section, in order to ensure the firmness of the cardboard box joints, if glue is used for fixing, the glue needs to be applied evenly and precisely to specific areas, which usually requires the use of specialized equipment or tools, increasing the complexity of the operation; the amount of glue used needs to be precisely controlled during the glue application process to avoid too much or too little, which requires a high level of skill from the operator; the glue needs a certain amount of time to dry and cure completely, and the waiting time directly affects production efficiency.

[0038] If self-adhesive stickers are used for fixing, the size of the stickers needs to be cut according to the corresponding position, and special equipment or tools are required, which increases the complexity of the operation. The stickers also need to be aligned with the corresponding position during the application process; otherwise, stickers that are not in the designated area will cause unsightly damage or even affect the placement of products inside the box. During the assembly of the box, the film on the self-adhesive stickers needs to be removed, which also increases the assembly process and time, and reduces assembly efficiency.

[0039] In view of this, embodiments of this application provide an adhesive packaging box. By clamping at least a portion of the interlocking plate between the inner and outer panels and utilizing the interlocking of the first and second interlocking parts, the assembly of the top panel, the first adhesive component, and the second adhesive component does not require the use of glue or self-adhesive stickers, reducing reliance on specialized equipment and tools and lowering operational complexity. The interlocking structure of the first and second interlocking parts enables rapid fixing, eliminating the waiting time for glue drying and self-adhesive sticker alignment, thus improving production efficiency. The design of the interlocking parts provides a robust connection, ensuring the stability and sealing of the top panel and the main body. The cooperative use of the inner and outer panels increases support and pressure resistance. The use of glue and self-adhesive stickers is reduced, lowering material costs and environmental impact.

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0042] This application provides a glue-free packaging box, including a main body 100 and a top plate 200. The fixed end of the top plate 200 is connected to the main body 100, and the top plate 200 can cover the top of the main body 100.

[0043] The top plate 200 is provided with a first fitting member 300 and a second fitting member 400 that can fit against the outside of the main body 100. The first fitting member 300 is located at the movable end of the top plate 200, and the second fitting member 400 is located on the side of the top plate 200.

[0044] The first mating component 300 includes an inner plate 310 and an outer plate 320 connected to each other. The outer plate 320 is located inside the outer plate 320, and the inner plate 310 is provided with a first insertion part 321.

[0045] The second mating part 400 is provided with a plug plate 410 on the side near the movable end. At least a portion of the plug plate 410 is located between the inner plate 310 and the outer plate 320. The plug plate 410 is provided with a second plug part 411, and the first plug part 321 and the second plug part 411 are plugged in and engaged.

[0046] It should be noted that, for ease of understanding, the above description is a description of the assembled packaging box, not a description of the unfolded packaging box.

[0047] refer to Figures 1-5 To make it easier to indicate that the dotted line represents the part of the first bonding component 300 that is covered, it can be understood that the main body 100 serves as the main storage space of the packaging box, used to place and protect the product.

[0048] The fixed end of the top plate 200 is connected to the main body 100 and can be placed on the top of the main body 100 to form a closed structure.

[0049] The first fitting element 300 and the second fitting element 400 surround the side of the top plate 200 to form a cover structure, allowing it to be fastened to the main body 100 and flexibly open and close the cavity of the main body 100. It should be noted that when the top plate 200 is fastened to the main body 100, the first fitting element 300 and the second fitting element 400 are attached to the outer side wall of the main body 100.

[0050] At least a portion of the plug-in plate 410 is located between the inner plate 310 and the outer plate 320, indicating that the inner plate 310 presses a portion of the plug-in plate 410 onto the outer plate 320. The first plug-in portion 321 of the inner plate 310 and the second plug-in portion 411 of the plug-in plate 410 are plugged in and engaged, serving as a locking mechanism. At the same time, since the plug-in plate 410 is pressed under the inner plate 310, the second plug-in portion 411 of the plug-in plate 410 will suppress the upward flipping tendency of the first plug-in portion 321 of the inner plate 310. It is equivalent to the inner plate 310 of the first bonding member 300 fixing the second bonding member 400 by stacking, while the plug-in plate 410 of the second bonding member 400 fixing the first bonding member 300, forming an interlocking structure, which serves as a structural fixation mechanism and avoids fixation by adhesive method.

[0051] By clamping at least a portion of the plug-in plate 410 between the inner plate 310 and the outer plate 320, and utilizing the first plug-in portion 321 and the second plug-in portion 411 for interlocking, the assembly of the top plate 200, the first bonding member 300, and the second bonding member 400 does not require the use of glue or self-adhesive stickers, reducing reliance on specialized equipment and tools and lowering operational complexity. The interlocking structure of the first plug-in portion 321 and the second plug-in portion 411 enables rapid fixing, eliminating the waiting time for glue drying and self-adhesive sticker alignment, thus improving production efficiency. The design of the plug-in plate 410 provides a robust connection, ensuring the stability and sealing of the top plate 200 and the main body 100. The combined use of the inner plate 310 and the outer plate 320 increases support and pressure resistance. The reduced use of glue and self-adhesive stickers lowers material costs and environmental impact.

[0052] In some possible implementations, the first plug portion 321 is configured as a plug connector, and the second plug portion 411 is configured as a plug slot, wherein the plug connector can be inserted into the plug slot.

[0053] It is known that the first plug-in portion 321 (plug connector) is designed to be inserted into the second plug-in portion 411 (plug slot). The first plug-in portion 321 (plug connector) is fixed by the second plug-in portion 411 (plug slot), so that the outer plate 320 is fixed by the plug plate 410, preventing the outer plate 320 from tilting upwards, and making the outer plate 320 fit against the inner plate 310, which is equivalent to forming the front edge of the cover.

[0054] The second plug part 411 (plug slot) is designed to accommodate the plug and provides a fixing point for the first plug part 321 (plug).

[0055] The mating of the connector and slot provides a secure connection, simplifying the assembly process; the elimination of glue or adhesive stickers reduces reliance on specialized equipment and tools, and lowers operational complexity.

[0056] In some possible implementations, the plug-in plate 410 includes a first connecting plate 412 and a second connecting plate 413 connected together, with the first connecting plate 412 located between the inner plate 310 and the outer plate 320.

[0057] The second connecting plate 413 is located on the outside of the inner plate 310 and the outer plate 320. The second connecting plate 413 is attached to the top plate 200 and is provided with a plug-in groove.

[0058] It is known that the first connecting plate 412 is located between the inner plate 310 and the outer plate 320, ensuring that the first connecting plate 412 can provide stable support and connection between the inner plate 310 and the outer plate 320, and that the position of the second bonding member 400 can be fixed by the inner plate 310 and the outer plate 320.

[0059] Referring to the figure, the second connecting plate 413 is bent relative to the first connecting plate 412 and fits against the top plate 200, providing a fixing point for the first insertion part 321 (plug).

[0060] By setting a first connecting plate 412 and a second connecting plate 413 in the plug-in plate 410, and setting a plug-in groove on the second connecting plate 413, the packaging carton achieves a more stable glue-free fixing method, which improves the assembly efficiency of the packaging carton; the design of the first connecting plate 412 and the second connecting plate 413 provides multi-level support and connection, ensuring the stability of the structure.

[0061] In some possible implementations, the first end of the inner plate 310 is connected to the outer plate 320, and the second end of the inner plate 310 is provided with a connector.

[0062] When the connector is inserted into the connector slot, at least a portion of the connector is located between the top plate 200 and the second connecting plate 413.

[0063] It is known that the first end of the inner plate 310 is connected to the outer plate 320, ensuring that the inner plate 310 and the outer plate 320 form an integral structure, providing a stable foundation. The plug is designed at the second end of the inner plate 310, so that it can cooperate with the plug slot after the inner plate 310 is folded relative to the outer plate 320 to achieve a stable connection.

[0064] When the connector is inserted into the socket, at least a portion of the connector is pressed between the top plate 200 and the second connecting plate 413. This clamping action allows the connector to be stably fixed in the socket and prevents it from loosening.

[0065] During assembly, due to the bendability of the cardboard box itself, after the connector is placed into the connector slot, the connector is bent to fit between the connector slot and the top plate 200 to avoid protrusion.

[0066] In some possible implementations, the length of the inner panel 310 is less than the length of the outer panel 320; or, the length of the inner panel 310 is equal to the length of the outer panel 320.

[0067] It is known that when the length of the inner plate 310 is less than the length of the outer plate 320, the inner plate 310 can be more easily positioned and operated during insertion, because the shorter inner plate 310 can be better inserted into the insertion slot under the protection of the outer plate 320.

[0068] When the length of the inner panel 310 is equal to the length of the outer panel 320, ensuring that the edges of the two are aligned, a larger contact area and support force can be provided, ensuring the overall stability of the inner panel 310 and the outer panel 320.

[0069] By changing the length design of the inner panel 310 and the outer panel 320, higher structural stability and support can be provided as needed. Different length designs can be selected according to different application requirements to provide the best performance and user experience.

[0070] In some possible implementations, there may be two second bonding members 400, which are arranged opposite to each other.

[0071] The plug plates 410 of the two second bonding components 400 are used in conjunction with the first bonding component 300.

[0072] Understandably, the two second bonding parts 400 are positioned opposite each other, and this symmetrical design helps to distribute the force evenly, ensuring the stability of the packaging box in all directions.

[0073] The plug plates 410 of the two second mating parts 400 are used in conjunction with the first mating part 300 to ensure the robustness of the plug-in structure and provide a stronger fixing effect through multiple contact points.

[0074] With the plug plate 410 used in conjunction with the first fitting member 300, the second fitting member 400 forms the two side edges of the cover, which together with the front edge formed by the first fitting member 300 and the top plate 200 form the cover structure, which can be fastened to the main body 100.

[0075] During assembly, firstly, the second mating part 400 is bent relative to the top plate 200 (generally at 90°), and the insert plate 410 is bent relative to the second mating part 400 (generally at 90°); the inner plate 310 is bent relative to the top plate 200 (generally at 90°), and the insert plate 410 is then mated with the inner plate 310; next, the outer plate 320 is bent and mated with the inner plate 310, and the insert plate 410 is sandwiched between the inner plate 310 and the outer plate 320; the second connecting plate 413 is bent relative to the first connecting plate 412 and then mated with the top plate 200; the first insert part 321 and the second insert part 411 are then inserted and mated, and the second insert part 411 is bent and mated with the top plate 200. It should be noted that the above folding and assembly sequence is not unique and can be adjusted according to actual operating habits.

[0076] In some possible implementations, the main body 100 includes a base plate 110 and a plurality of side plates 120 disposed at the edge of the base plate 110.

[0077] The multiple side panels 120 include two first side panels 121 arranged opposite to each other and two second side panels 122 arranged opposite to each other. The first side panels 121 are connected to the two second side panels 122, and the second side panels 122 are connected to the two first side panels 121.

[0078] As can be seen from the slippage, the base plate 110, as the foundation of the packaging box, bears the weight of the entire structure and the internal products.

[0079] Multiple side panels 120 are disposed at the edge of the base plate 110 to form the side walls of the packaging box, providing lateral support and protection.

[0080] The two first side plates 121 are arranged opposite each other to provide longitudinal support and stability; the two second side plates 122 are arranged opposite each other to provide lateral support and stability; the staggered connection of the first side plates 121 and the second side plates 122 forms a closed frame structure, which improves the overall rigidity and stability.

[0081] The design of the base plate 110 and multiple side plates 120 provides multi-directional support and stability, ensuring the safety of the packaging box during transportation and storage. The relative arrangement and connection of the side plates 120 enables a fixation method without glue or self-adhesive stickers, reducing reliance on specialized equipment and tools. The design of the plates 120 enables rapid assembly through staggered connections, eliminating the waiting time for glue drying and self-adhesive sticker alignment.

[0082] refer to Figure 4 In some possible implementations, the first side plate 121 is provided with a connecting structure 123, and the connecting structures 123 of the two first side plates 121 are connected to each other.

[0083] The second side plate 122 is located outside the two connecting structures 123. The second side plate 122 is provided with a connector 1221 and is fixed to the connecting structure 123 through the connector 1221.

[0084] It is understood that each first side plate 121 is provided with a connecting structure 123 for connecting two first side plates 121 to each other. The connecting structure 123 is located inside the second side plate 122 and can also provide additional lateral support.

[0085] By providing a connecting structure 123 on the first side plate 121 and a connector 1221 on the second side plate 122, the packaging box achieves a stable glue-free fixing method, which simplifies the assembly process and enhances the stability of the overall structure.

[0086] In some embodiments, the connecting structure 123 has a first through hole 141 and the second side plate 122 has a corresponding second through hole 142. The first through hole 141 and the second through hole 142 overlap to form a point of leverage for lifting the packaging box.

[0087] In some possible implementations, the connecting structure 123 is provided with a hook part 1231, the hook parts 1231 of the two connecting structures 123 are staggered, and the hook parts 1231 of the two connecting structures 123 are used in conjunction.

[0088] Understandably, the hook portion 1231 is used to achieve a mechanical connection between the two connecting structures 123. The hook portions 1231 of the two connecting structures 123 are misaligned, ensuring that the two connecting structures 123 can achieve a stable interlock through the hook portions 1231. Through the interlocking of the hook portions 1231, the positions of the two first side plates 121 are fixed, preventing the two first side plates 121 from tilting outward and maintaining the structural stability of the main body 100.

[0089] The design of the hook part 1231 provides a robust mechanical connection, ensuring the safety of the packaging carton during transportation and storage; the design of the hook part 1231 enables a fixation method without glue or self-adhesive stickers, reducing reliance on specialized equipment and tools; the design of the hook part 1231 enables rapid assembly through mechanical interlocking, eliminating the waiting time for glue drying and self-adhesive sticker alignment.

[0090] In some possible implementations, a mounting port 130 is provided between the connecting structure 123 and the first side plate 121; the connector 1221 can be inserted into the mounting port 130.

[0091] It is understood that the mounting port 130 is designed to accommodate the connector 1221 to achieve a stable connection; the connector 1221 can be inserted into the mounting port 130, and through this insertion method, the connector 1221 fixes the second side plate 122 to the first side plate 121.

[0092] The design of mounting port 130 and connector 1221 provides a robust mechanical connection, ensuring the safety of the packaging carton during transportation and storage; the design of mounting port 130 and connector 1221 enables a fixation method without glue or self-adhesive stickers, reducing reliance on specialized equipment and tools; the design of mounting port 130 and connector 1221 enables rapid assembly through mechanical interlocking, improving assembly efficiency.
