[0002] Corrugated boxes are a common packaging container used in logistics, warehousing, and daily life for packaging, transporting, and storing various items. However, traditional corrugated boxes have many shortcomings in terms of waterproof performance, structural strength, and tearability.

[0003] First, traditional corrugated boxes often suffer from material or structural design flaws, making them prone to water leakage in humid or rainy environments, thus affecting the quality of the contents. Second, during transportation, corrugated boxes may be subjected to external impacts such as drops and compression. If the structural strength is insufficient, the box may deform or even break, damaging the contents. Furthermore, traditional corrugated boxes often require tools such as scissors or knives to open, which not only increases the complexity of use but also risks damaging the contents due to improper handling.

[0004] Chinese Patent No. CN202222287654.X discloses a corrugated cardboard box with a cushioning structure. It achieves the effect of protecting the corrugated box body by installing a fixing frame at the bottom inside the corrugated box body and using a spring damper structure. However, the corrugated box has problems such as poor waterproof performance, inconvenient opening, easy damage to the internal items due to moisture, and complicated operation that may damage the internal items. In view of this, a waterproof and easy-to-tear corrugated box is provided. Utility Model Content

[0005] The main purpose of this utility model is to provide a waterproof and easy-to-tear corrugated box to solve the problems mentioned in the related technology, such as poor waterproof performance, inconvenient opening, easy damage to internal items due to moisture, and complicated operation that may damage internal items.

[0006] To achieve the above objectives, according to one aspect of this utility model, a waterproof and easy-to-tear corrugated box is provided, comprising a main shell, side shells symmetrically connected to both ends of the main shell, connecting shells and sealing shells fixedly connected to both ends of the main shell, with the connecting shells and sealing shells facing each other, fixing plates fixedly connected to the four corner edges of the inner wall of the main shell, the fixing plates being used to enhance the structural strength of the main shell, and a waterproof plate fixedly connected inside the main shell, with two sets of tear-off notches symmetrically opened through the sealing shell on both sides.

[0007] Furthermore, the fixing plate has a triangular arc-shaped structure and is made of reinforced fiberboard.

[0008] Furthermore, the waterproof membrane has a rounded rectangular structure, and several partitions are fixedly connected to the side wall of the waterproof membrane, and the side wall of the partitions is fixedly connected to the inner wall of the main shell.

[0009] Furthermore, the waterproof membrane has several buffer layers fixedly connected to its sidewalls. The buffer layers are located between two adjacent partitions, and the space between the two adjacent partitions is filled with moisture-absorbing material.

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] Please see Figures 1-7 As shown, the purpose of this embodiment is to provide a waterproof and easy-to-tear corrugated box, including a main shell 1. Side shells 2 are symmetrically connected to both ends of the main shell 1. Connecting shells 3 and sealing shells 4 are fixedly connected to both ends of the main shell 1, and the connecting shells 3 and sealing shells 4 are arranged opposite to each other. Fixing plates 11 are fixedly connected to the four corner edges of the inner wall of the main shell 1. The fixing plates 11 are used to enhance the structural strength of the main shell 1. A waterproof plate 5 is fixedly connected inside the main shell 1. Two sets of tear-off notches 43 are symmetrically opened through the sealing shells 4.

[0030] The fixing plate 11 has a triangular arc-shaped structure, which is not only aesthetically pleasing, but also, due to the stability principle of a triangle, allows it to effectively resist forces and pressures from all directions. The arc-shaped design helps to disperse these forces, reducing stress concentration points and thus extending the service life of the corrugated box. Furthermore, the fixing plate 11 is made of reinforced fiberboard, combining the lightweight of cardboard with the strength of fiber materials, enabling it to withstand greater loads. It also possesses excellent tear and bending resistance, which is crucial for improving the overall structural strength of the corrugated box. The fixing plate 11 is fixedly connected to the four corner edges of the inner wall of the main shell 1, forming a stable support frame that can resist external impacts and compression, protecting the internal contents from damage.

[0031] For waterproofing, the waterproof membrane 5 uses an environmentally friendly waterproof coating that is non-toxic and harmless, with no adverse effects on human health or the environment. Simultaneously, the waterproof membrane 5 has a rounded rectangular structure, improving its tear and bending resistance. It also adheres to the inner wall of the main housing 1, forming an effective waterproof barrier to prevent moisture and damage to internal items. Several partitions 51 are fixedly connected to the sidewalls of the waterproof membrane 5, and the sidewalls of these partitions 51 are fixedly connected to the inner wall of the main housing 1. Therefore, the waterproof membrane 5 is fixedly connected inside the main housing 1.

[0032] Several buffer layers 52 are fixedly connected to the side wall of the waterproof board 5. The buffer layer 52 is located between two adjacent partitions 51. Its main function is to absorb and disperse the impact force from the outside and protect the internal items from damage. The space between the two adjacent partitions 51 is also filled with moisture-absorbing materials, such as silica gel and activated carbon, which can absorb and lock in the moisture in the air and prevent the internal items from getting damp and deteriorating. Especially in humid or high-temperature environments, it not only improves the waterproof performance of the corrugated box, but also extends the shelf life of the internal items. In addition, the waterproof board 5 can block the penetration of water.

[0033] An adhesive tape layer 41 is fixedly connected to the inner wall of one end of the sealing shell 4. A high-performance pressure-sensitive adhesive material is selected. This material not only ensures that the adhesive tape layer 41 has excellent adhesion, but also has excellent sealing performance, effectively preventing the intrusion of external moisture and dust, creating a dry and clean storage environment for the inside of the corrugated box. Furthermore, a semi-circular slot 31 is provided through one end of the connecting shell 3. This semi-circular slot 31 not only provides a comfortable grip space for the user, allowing the user to easily insert their fingers and apply force when folding and sealing the corrugated box, but its smooth lines and rounded edges also prevent the user from being scratched or uncomfortable during use.

[0034] When using the corrugated box for packing, the user must first fold the side shell 2 inwards by 90° to tightly connect it with the main shell 1, forming a complete and stable box structure. Figure 1As shown, the connecting shell 3 is then folded inwards by 90°, ensuring its sidewall fits tightly against the sidewall of the side shell 2. Finally, the sealing shell 4 is folded inwards by 90°, ensuring its sidewall fits tightly against the sidewall of the connecting shell 3. At this point, the user simply needs to gently press the sealing shell 4 to firmly adhere the adhesive layer 41 to the sidewall of the connecting shell 3, thus sealing the corrugated box and ensuring a dry and clean internal environment. It is worth noting that during the sealing process, the user needs to ensure that the adhesive layer 41 is smoothly adhered to the sidewall of the connecting shell 3 without air bubbles to further improve the sealing performance of the corrugated box. Simultaneously, due to the excellent adhesion and sealing properties of the adhesive layer 41, it maintains a stable adhesion effect even in humid or high-temperature environments, thereby ensuring a long-term dry and clean internal environment for the corrugated box.

[0035] A rigid strip 42 is embedded within the sealing shell 4, located between two sets of notches 43, providing crucial structural support. The rigid strip 42 also provides the user with a clear tearing direction. Several grooves 44 are symmetrically formed along the left and right sides of the sealing shell 4, aligned vertically with the notches 43, providing a clear tearing path. Creases are formed between the grooves 44 at the top and bottom, further enhancing the ease of tearing the sealing shell 4. When opening the corrugated box, simply pull the solid portion between the notches 43. With forceful tearing, the grooves 44 are first pulled open, forming a clear tear line. Under the combined action of the rigid strip 42 and the creases, the sealing shell 4 folds and breaks along the predetermined path, ultimately tearing out a complete strip to open the corrugated box. The entire process is simple and easy, requiring no additional tools or equipment, providing great convenience to the user.

[0036] Several reinforcing strips 12 are fixedly connected to the outer wall of the main shell 1. The reinforcing strips 12 are wavy in shape. During the transportation of the corrugated box, the reinforcing strips 12 can withstand the impact force from the outside to a certain extent. When the box is subjected to impacts such as drops, squeezing, or collisions, the reinforcing strips 12 can respond quickly and absorb the impact force, thereby protecting the main shell 1 and the contents from damage. At the same time, the wavy design of the reinforcing strips 12 also gives the corrugated box a more beautiful and unique appearance, enhancing its market competitiveness.

[0037] In practical use, when a corrugated box needs to be packaged, fold the side shells 2 at one end of the corrugated box inward by 90°. Then, fold the connecting shell 3 inward by 90°, so that its side wall is tightly fitted with the side wall of the folded side shell 2. Finally, fold the sealing shell 4 inward by 90°, so that its side wall is tightly fitted with the side wall of the connecting shell 3. It is necessary to ensure that the adhesive tape layer 41 is tightly adhered to the outer wall of the connecting shell 3. Then, put the items into the corrugated box, seal the other end of the corrugated box according to the above steps, and the moisture in the air inside the corrugated box is blocked by the partition 5. The moisture-absorbing material in section 1 absorbs moisture to maintain dryness and waterproof performance; when it is necessary to open the corrugated box, simply pull the solid part between the notches 43 at both ends of the sealing shell 4. As the user pulls hard, the groove 44 will be pulled open first, forming a clear tear line. Under the combined action of the hard strip 42 and the crease, the sealing shell 4 will fold and break along the predetermined path, and finally tear out a complete strip to open the corrugated box. Then unfold the sealing shell 4, and then insert your fingers into the slot 31 to rotate and open the connecting shell 3. Finally, open the side shell 2 to take out the items inside the corrugated box.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
