Description

Technical Field

[0001] This utility model relates to the field of packaging paper box technology, and in particular to a green anti-crushing packaging paper box with multi-layer composite dynamic cushioning of biodegradable materials. Background Technology

[0002] In recent years, with the transformation of social lifestyles and the growing popularity of environmental protection concepts, the lunchbox packaging industry is undergoing unprecedented technological innovation. Green anti-crush packaging boxes with multi-layer composite dynamic cushioning made of biodegradable materials are a product that conforms to this trend.

[0003] However, in the current technology, existing biodegradable packaging boxes lack user-friendly opening guidance designs. Most packaging boxes rely solely on simple opening prompts, without considering the differences in strength and usage habits of different users. They do not have structures or auxiliary opening parts to facilitate the application of force. Users can only try to open them based on experience and intuition. This leads to the embarrassing situation in actual use where users cannot control the opening force, often resulting in the box being torn apart by excessive force or unable to open the packaging due to insufficient force, which greatly affects the user experience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a green, compression-resistant packaging cardboard box with multi-layered composite dynamic cushioning made of biodegradable materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a green anti-crush packaging paper box with multi-layer composite dynamic cushioning of biodegradable materials, comprising: a paper box bottom plate, wherein a paper box top plate is slidably connected to the paper box bottom plate;

[0006] A cardboard box connecting assembly includes a rubber connecting layer fixedly connected to a cardboard box base plate, a rigid plastic layer fixedly connected to the rubber connecting layer, a second connecting plate fixedly connected to a cardboard box top plate, a conical block fixedly connected to the cardboard box base plate via a first connecting plate, a vertical rod fixedly connected to the first connecting plate via a horizontal bar, a transmission block slidably connected to the vertical rod, a fixing ring fixedly connected to the cardboard box base plate, and a connecting rod fixedly connected to the transmission block.

[0007] In a preferred embodiment, both the first connecting plate and the bottom plate of the cardboard box have openings. A crossbar is slidably connected to the openings on the bottom plate of the cardboard box and the first connecting plate. A limiting plate is provided on the crossbar. There are two limiting plates. The limiting plate on the side away from the rigid plastic layer is slidably connected to the crossbar, and the limiting plate on the side closer to the rigid plastic layer is fixedly connected to the crossbar.

[0008] The above technical solution employs the following: During use, a limiting plate fixed to the crossbar acts as a stop, preventing the crossbar from completely detaching from the cardboard box bottom plate. A sliding limiting plate also serves a stopping function. After the crossbar is pulled out of the cardboard box bottom plate, pressing the sliding limiting plate causes it to hook onto the outer wall of the bottom plate via barbs. Finally, a plastic rod is inserted into an opening on the crossbar to complete the stopping of the crossbar.

[0009] In a preferred embodiment, the transmission block is provided with an inclined groove, and the vertical rod is slidably connected in the inclined groove.

[0010] The above technical solution allows the transmission block to move when the vertical rod slides in the inclined groove.

[0011] In a preferred embodiment, a fixing tube is fixedly connected to the bottom plate of the cardboard box, and a fastening cap is threaded onto the fixing tube.

[0012] The above technical solution involves fixing a tube to the bottom plate of the cardboard box, allowing spare plastic rods to be inserted into the tube for storage during use.

[0013] In one preferred embodiment, a barbed hook is fixedly connected to the limiting plate.

[0014] Using the above technical solution: when in use, the barbs on the limiting plate can initially hang the limiting plate on the bottom plate of the cardboard box.

[0015] In one preferred embodiment, the crossbar has an opening.

[0016] The above technical solution is adopted: by opening holes in the crossbar, it is easy to insert a plastic rod to limit the crossbar and prevent the two first connecting plates from detaching from the bottom plate of the cardboard box at different times.

[0017] In a preferred embodiment, an opening is provided on the side of the second connecting plate near the first connecting plate.

[0018] The above technical solution is adopted: by opening a hole in the second connecting plate, it is convenient to use the conical block to be inserted into the opening in the second connecting plate to complete the fixation of the top plate and the bottom plate of the cardboard box.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, one of the two limiting discs is fixedly connected to the crossbar, while the other is slidable. During disassembly, the user only needs to remove the slidable limiting disc from the outer wall of the cardboard box bottom plate, releasing the fixed state formed by the barbed engagement transmission. Then, press the crossbar. During the retraction of the crossbar, it drives the vertical rod to slide in the opposite direction within the inclined groove of the transmission block. Utilizing the inclined surface transmission principle of the inclined groove, the transmission block drives the connecting rod to slide to both sides, disengaging from the clamping of the fixed ring. In this way, the first connecting plate loses its secondary fixing constraint and can be easily removed along with the top plate of the cardboard box. The entire disassembly process does not require additional tools, and the operation is simple and intuitive. This solves the problem in the prior art where excessive force often tears the cardboard box or insufficient force prevents the packaging from being opened. Attached Figure Description

[0032] 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.

[0033] A green, compression-resistant packaging cardboard box with multi-layer composite dynamic cushioning made of biodegradable materials, comprising: a cardboard box base plate 1, and a cardboard box top plate 11 slidably connected to the cardboard box base plate 1;

[0034] The cardboard box connecting assembly 2 includes a rubber connecting layer 22 fixedly connected to the cardboard box bottom plate 1, a rigid plastic layer 21 fixedly connected to the rubber connecting layer 22, a second connecting plate 5 fixedly connected to the cardboard box top plate 11, a conical block 24 fixedly connected to the cardboard box bottom plate 1 via a first connecting plate 23, a vertical rod 26 fixedly connected to the first connecting plate 23 via a horizontal bar 25, a transmission block 27 slidably connected to the vertical rod 26, a fixing ring 28 fixedly connected to the cardboard box bottom plate 1, and a connecting rod 29 fixedly connected to the transmission block 27.

[0035] In this utility model, when food is placed on the rigid plastic layer 21, the rigid plastic layer 21 will move down slightly, causing the rubber connecting layer 22 to undergo slight elastic deformation. At this time, the crossbar 25 is pushed out a bit, and the staff can pinch the crossbar 25, pull it out, and press the limiting plate 210 to make it hang on the outer wall of the cardboard box bottom plate 1.

[0036] During this process, the vertical rod 26 is moved by the horizontal rod 25 and slides in the inclined groove 3 on the transmission block 27, which drives the inclined grooves 3 on both sides to move inward and clamp the connecting rod 29 into the fixing ring 28. At this time, the tightness of the connection between the first connecting plate 23 and the bottom plate 1 of the carton is enhanced, and it is not just the first connecting plate 23 and the bottom plate 1 of the carton that are connected by the horizontal rod 25.

[0037] Align and snap the crossbar 25 fixed at the bottom of the top plate 11 of the cardboard box with the conical block 24 to complete the connection between the bottom plate 1 and the top plate 11 of the cardboard box.

[0038] Since the transmission block 27 is pressed against the bottom of the inner wall of the cardboard box base plate 1, it will not be displaced.

[0039] When it is necessary to separate the bottom plate 1 of the cardboard box from the top plate 11 of the cardboard box, simply remove the limiting plate 210 from the bottom plate 1 of the cardboard box and press the crossbar 25 into the bottom plate 1 of the cardboard box. At this time, the crossbar 25 drives the vertical bar 26 to slide on the inclined groove 3, and the transmission block 27 drives the connecting rod 29 to slide to both sides to disengage from the fixing ring 28. At this time, the first connecting plate 23 can be removed together with the top plate 11 of the cardboard box.

[0040] like Figures 1 to 5 As shown, both the first connecting plate 23 and the bottom plate 1 of the cardboard box have openings. A crossbar 25 is slidably connected to the bottom plate 1 and the opening on the first connecting plate 23. A limiting plate 210 is provided on the crossbar 25. There are two limiting plates 210. The limiting plate 210 on the side away from the rigid plastic layer 21 is slidably connected to the crossbar 25, and the limiting plate 210 on the side closer to the rigid plastic layer 21 is fixedly connected to the crossbar 25. The first connecting plate 23 and the bottom plate 1 have openings at corresponding positions, and the sliding crossbar is built into them. 25. Two limiting discs 210 are provided on the crossbar 25. The limiting disc 210 closer to the rigid plastic layer 21 is fixedly connected to the crossbar 25 to prevent the crossbar 25 from completely detaching from the cardboard box base 1 during use, ensuring the integrity of the packaging structure. The limiting disc 210 further away from the rigid plastic layer 21 is slidably connected to the crossbar 25. When the crossbar 25 is pulled out from the cardboard box base 1, pressing this sliding limiting disc 210 allows its barbed structure to quickly hook onto the outer wall of the cardboard box base 1. A plastic rod is then inserted into the opening of the crossbar 25 for secondary positioning. This design ensures the stability of the packaging connection during transportation and allows users to control the force when unpacking, avoiding damage to the packaging due to improper force.

[0041] like Figure 4 As shown, the transmission block 27 has an inclined groove 3, and the vertical rod 26 is slidably connected within the inclined groove 3. When the horizontal rod 25 drives the vertical rod 26 to move, according to the principle of inclined plane transmission, the sliding of the vertical rod 26 within the inclined groove 3 is converted into the lateral displacement of the transmission block 27, thereby driving the connecting rod 29 to perform an opening and closing action. Through this transmission method, the connection between the first connecting plate 23 and the bottom plate of the carton is upgraded from a single horizontal rod 25 connection to a double stable connection structure. When the packaging is subjected to external pressure, this structure can effectively disperse the impact force, significantly improve the anti-crushing performance of the packaging and the reliability of the connection, and provide more reliable protection for the contents.

[0042] like Figures 1 to 5 As shown, a fixing tube 4 is fixedly connected to the bottom plate 1 of the cardboard box, and a fastening cap 41 is threadedly connected to the fixing tube 4. The fixing tube 4 is fixedly installed on the bottom plate 1 of the cardboard box and equipped with a threaded fastening cap 41. This fixing tube 4 is specially designed to store spare plastic rods. The threaded fastening cap 41 can securely seal the plastic rods to prevent them from falling off and being lost during transportation. When it is necessary to limit and fix the crossbar 25, the user can take out the plastic rod from the fixing tube 4 at any time and insert it into the opening of the crossbar 25 to achieve the limit operation. This integrated storage design improves the convenience and efficiency of operation in the packaging assembly and disassembly process.

[0043] like Figure 5As shown, a barb is fixedly connected to the limiting disc 210. When the limiting disc 210 contacts the bottom plate 1 of the cardboard box, the barb can initially engage with the surface of the bottom plate 1, assisting the barb structure in achieving a quick and stable limiting effect. Compared to relying solely on barbs for limiting, the presence of the barb effectively reduces the difficulty for users to press the limiting disc 210, making the limiting process easier and faster, further enhancing the stability of the limiting and optimizing the user experience during packaging operations.

[0044] like Figure 5 As shown, the crossbar 25 has an opening of a specific size. This opening is adapted to the spare plastic rod. When the plastic rod is inserted, it can effectively limit the movement range of the crossbar 25, ensuring that the first connecting plates 23 on both sides can be subjected to force and detach from the bottom plate 1 of the cardboard box simultaneously during the packaging disassembly process. This design avoids the situation where the packaging is damaged due to excessive local force caused by asynchronous disassembly, ensuring the integrity and smoothness of the packaging disassembly process and improving the reliability of the packaging.

[0045] like Figures 1 to 3 As shown, an opening is provided on the side of the second connecting plate 5 near the first connecting plate 23. The opening matches the size and shape of the conical block 24 fixed on the bottom plate 1 of the carton. During the packaging assembly process, the top plate 11 of the carton is slid down, and the conical block 24 can be smoothly inserted into the opening of the second connecting plate 5 to form a tight fitting connection. This connection method not only simplifies the assembly process of the top plate 11 and the bottom plate of the carton, but also effectively disperses the impact of external forces during transportation, enhances the stability of the overall packaging structure, and provides solid and reliable protection for the contents.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
