[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products, and their usage has always been the highest among all packaging products, including calcium-plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also beautify and promote goods. Corrugated boxes are green and environmentally friendly products, which are beneficial to the environment and facilitate loading, unloading and transportation.

[0003] Traditional corrugated cardboard express boxes typically rely on a large amount of tape for sealing. The sealing process requires manual cutting and pasting of tape, which is not only cumbersome and time-consuming, reducing logistics packaging efficiency, but also, since most tapes are made of non-biodegradable plastic, the resulting "tape waste" causes serious environmental pollution, contradicting the current advocacy of green and environmentally friendly concepts. At the same time, the process of unpacking the express box is also extremely inconvenient for consumers, often requiring the use of tools such as scissors and utility knives. Improper handling may result in hand injuries or damage to the goods inside the box, posing certain safety hazards. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a quick-release, tape-free corrugated cardboard express box technical solution: It includes a cardboard box 1, with two cover plates 2 connected to the top of the cardboard box 1. Each cover plate 2 has a magnetic attraction structure 3 on its top. The magnetic attraction structure 3 includes two connecting blocks 301 installed on the top of the cardboard box 1. Each connecting block 301 is externally connected to a flexible pull plate 302. Each flexible pull plate 302 has a first mounting groove 307 at its bottom, and a first flexible magnet 306 is installed inside each first mounting groove 307. Each cover plate 2 has a groove on its top. The slot 303 has a second mounting slot 304 inside, and a second flexible magnet 305 is installed inside each second mounting slot 304. The magnetic structure 3 has a snap-fit ​​structure 9 on the outside. The carton 1 is closed by two cover plates 2 in conjunction with the magnetic structure 3. The bottom of the flexible pull plate 302 is fixed by the connecting block 301. The first flexible magnet 306 in the first mounting slot 307 and the second flexible magnet 305 in the second mounting slot 304 in the slot 303 of the cover plate 2 form a magnetic attraction, which replaces the traditional tape to achieve sealing.

[0024] like Figure 1 and Figure 3 As shown, the snap-fit ​​structure 9 includes a first snap-fit ​​plate 901 and a second snap-fit ​​plate 902. The first snap-fit ​​plate 901 is connected to one of the flexible pull plates 302, and the second snap-fit ​​plate 902 is connected to the other flexible pull plate 302. The design of the first snap-fit ​​plate 901 and the second snap-fit ​​plate 902 respectively connecting to the two flexible pull plates 302 enhances the fixing effect of the magnetic attraction structure 3.

[0025] like Figure 3 As shown, the second card plate 902 has a first card slot 903 on its outside. The first card plate 901 is engaged with the second card plate 902 through the first card slot 903. The engagement design of the first card slot 903 of the second card plate 902 and the first card plate 901 achieves a balance between mechanical locking and convenient operation. The card slot connection eliminates the need for complicated alignment during the engagement process. The engagement can be completed by simply pushing the flexible pull plate 302. When opening, the flexible pull plate 302 can be pulled to separate the two plates.

[0026] like Figure 2 and Figure 4 As shown, the bottom of the carton 1 is connected to a first bottom cover 4 and a second bottom cover 5 respectively. The outside of the first bottom cover 4 is provided with a second slot 15, and the outside of the second bottom cover 5 is connected to a movable block 6. The movable block 6 is engaged with the first bottom cover 4 through the second slot 15. The engagement design of the first bottom cover 4 and the second bottom cover 5 at the bottom of the carton 1 through the movable block 6 and the second slot 15 solves the problem of stability and reusability of the bottom seal.

[0027] like Figure 1 and Figure 2As shown, the outer side of the carton 1 has two grip slots 7, and each grip slot 7 has a handle 8 installed inside. The design of the outer grip slots 7 and the inner handle 8 of the carton 1 improves the convenience and comfort of handling.

[0028] like Figure 4 As shown, four longitudinal strips 12 and four transverse strips 13 are installed inside the carton 1. Each longitudinal strip 12 is connected to the transverse strip 13. The connection design of the longitudinal strips 12 and transverse strips 13 inside the carton 1 enhances the overall load-bearing capacity and anti-deformation performance of the carton. The longitudinal strips 12 and transverse strips 13 form a grid-like support structure, which can distribute the pressure of the contents on the carton wall and prevent the side wall from collapsing due to the loading of heavy objects or stacking and squeezing.

[0029] like Figure 4 As shown, the interior of carton 1 is equipped with two first support bars 11 and two second support bars 14. Each first support bar 11 and each second support bar 14 is in contact with the first bottom cover 4 and the second bottom cover 5. The design of the first support bars 11 and the second support bars 14 contacting the first bottom cover 4 and the second bottom cover 5 enhances the bottom load-bearing capacity and structural stability. The bottom is the core area for the load-bearing of the carton. Through close contact with the bottom cover 2, the support bars evenly distribute the weight of the items to the entire bottom, preventing damage due to excessive local stress.

[0030] like Figure 3 As shown, each cover plate 2 has two through slots 10 on its upper part. The through slots 10 can serve as auxiliary force points when opening the box, and users can easily lift the cover plate 2 through the through slots 10.

[0031] The working principle of this utility model is as follows: When sealing, first flip the two cover plates 2 to cover the top opening of the carton 1, and then flip the flexible pull plate 302 fixed by the connecting block 301 downwards, so that the first flexible magnet 306 in the first mounting groove 307 at the bottom of the flexible pull plate 302 and the second flexible magnet 305 in the second mounting groove 304 in the groove 303 of the cover plate 2 are magnetically attached to achieve initial fixation. At the same time, the snap-fit ​​structure 9 outside the magnetic structure 3 forms a secondary reinforcement through the first snap-fit ​​plate 901 and the second snap-fit ​​plate 902 cooperating with the first snap-fit ​​groove 903. No tools are needed when opening. First, separate the snap-fit ​​effect of the snap-fit ​​structure 9, and then pull the flexible pull plate 302 to overcome the magnetic attraction force and separate the magnets. Finally, flip the cover plate 2 to open the carton 1.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
