[0002] Packaging boxes play a crucial role in product distribution. As an important packaging material, they fulfill multiple functions, including protecting products, facilitating storage, and supporting sales. Common types of packaging boxes include wooden crates, cardboard boxes, and plastic boxes.

[0003] Among the many types of packaging boxes available today, pallet cartons stand out. Their high strength allows for four-way forklift operation, greatly simplifying the workflow and effectively improving space utilization. Pallet cartons are primarily used for storing large items and play a crucial role in long-distance transportation, providing reliable packaging protection for large goods during their transit.

[0004] Some existing pallet cartons present significant environmental and functional problems. First, these cartons are mostly made of non-biodegradable materials, causing long-term environmental stress after disposal, which contradicts growing environmental protection demands. Second, traditional packing and securing methods are inefficient and lack stability, easily leading to damage to goods during transportation due to loose ropes or inconvenient packing. Furthermore, from a structural design perspective, traditional pallet cartons are mostly fixed structures; once one side is damaged, they become unusable, resulting in significant resource waste. Therefore, to address these issues, an environmentally friendly pallet carton is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an environmentally friendly pallet carton, which aims to improve the problems of existing pallet carton materials being difficult to recycle, unstable packaging, and non-replaceable structure after damage.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an environmentally friendly pallet carton, comprising a pallet base 1, two honeycomb paperboards (first type 2), two honeycomb paperboards (second type 3), and a carton lid 4. The pallet base 1, honeycomb paperboards (first type 2), honeycomb paperboards (second type 3), and carton lid 4 are all made of honeycomb paper core material, which is easily recyclable. The pallet base 1 is used to support the weight of the honeycomb paperboards and goods above. The inner wall of the bottom end of the carton lid 4 engages with the outer top end of the two honeycomb paperboards (first type 2), and the inner wall of the bottom end of the carton lid 4 engages with the outer top end of the two honeycomb paperboards (second type 3). The carton lid 4 is a frame-shaped paper lid, and the carton lid 4 wraps around the honeycomb paperboards (second type 3) and honeycomb paperboards (first type 2) through inner grooves, thereby increasing the stability of the top of the carton.

[0033] refer to Figure 2 , Figure 3 The bottom of the pallet base 1 is fixedly connected to three support legs 5, which are used to support the pallet base 1. The bottom of the pallet base 1 is detachably connected to four hook blocks 6. The hook blocks 6 are symmetrical structures that hang upside down at the bottom of the pallet base 1. The hook blocks 6 are used to provide fixing points for the packing ropes. During the packing process, one end of the rope is tied here.

[0034] Two collars 7 are fixedly connected to the opposite sides of two honeycomb cardboard units 2. The collars 7 are made of metal or plastic and have a suitable inner diameter to allow the packing rope to pass through smoothly and facilitate user disassembly of the honeycomb cardboard units 2. Four abutment rollers 8 are slidably connected to the side of the collars 7 away from the honeycomb cardboard units 2, sliding through the collars 7 on this side. A leaf spring 9 is fixedly connected to the end of each abutment roller 8 away from the honeycomb cardboard units 2. The inner side of the leaf spring 9 is fixedly connected to the abutment roller 8, and the outer side of the abutment roller 8 passes through the leaf spring 9 and connects to a limiting ring 10. The side of the leaf spring 9 closest to the rotating roller 11 is fixedly connected to the side of the collars 7 away from the honeycomb cardboard units 2. The leaf spring 9 has a certain elasticity, which can maintain pressure on the rotating roller 11 and the rope at all times, continuously assisting the rope sliding and positioning during the packing process, ensuring smooth packing operation and stable packing results.

[0035] Two abutment rollers 8 are fixedly connected to one end of the honeycomb cardboard 2 with limiting rings 10. A rotating roller 11 is rotatably connected to the inner wall of the middle portion of the two limiting rings 10. The limiting rings 10 ensure that the rotating roller 11 can rotate stably within the inner wall of the collar 7, while also cooperating with the abutment rollers 8. The outer part of the rotating roller 11 is rotatably connected to the inner wall of the collar 7, providing limiting and support for the rotating roller 11. When the rope passes through the collar 7, the rotating roller 11, under the pressure of the abutment rollers 8, makes close contact with the rope and rotates, reducing friction between the rope and the collar 7, allowing the rope to pass through the collar 7 more smoothly, improving packaging efficiency. Simultaneously, it cooperates with the abutment rollers 8 to position and assist in the sliding of the rope.

[0036] refer to Figure 1 , Figure 4 The honeycomb cardboard 12 has connecting components on both sides to assist in folding the carton. These components include four corner protectors 13. A square groove 12 is provided at the top of the pallet bottom 1. The outer bottom edge of the honeycomb cardboard 12 engages with the inner wall of the square groove 12. The square groove 12 has grooves at the top of the pallet bottom 1 that match the outer bottom edges of the honeycomb cardboard 12 and honeycomb cardboard 23. The outer bottom edge of the honeycomb cardboard 23 engages with the inner wall of the square groove 12. The adjacent sides of the corner protectors 13 are fixedly connected to the outside of the honeycomb cardboard 12. The square groove 12 provides engagement positions for the bottom edges of the honeycomb cardboard 12 and honeycomb cardboard 23, achieving precise positioning and connection between the honeycomb cardboard and the pallet bottom 1, thus enhancing the stability and integrity of the entire carton structure.

[0037] The corner protector 13 has a slot 14 on the side near the honeycomb paperboard 2 3. The corner protector 13 covers the connection between the honeycomb paperboard 1 2 and the honeycomb paperboard 2 3, increasing the rigidity of the carton's corners. The bottom of the slot 14 engages with the inner wall of the square groove 12, and the front and rear sides of the honeycomb paperboard 2 3 engage with the inner wall of the slot 14. The slot 14 serves two purposes: firstly, it protects and strengthens the corners of the honeycomb paperboard 1 2; secondly, it engages with the locking blocks of the honeycomb paperboard 2 3 to connect the honeycomb paperboard 2 3 and the honeycomb paperboard 1 2, jointly constructing the side structure of the carton and improving its stability and reliability.

[0038] Corner protectors 15 are fixedly connected to the four outer corners of the carton lid 4. The inner bottom wall of the corner protector 15 engages with the outer top of the slot 14, the inner bottom wall of the corner protector 15 engages with the outer top of the honeycomb paperboard 2 3, and the inner bottom wall of the corner protector 15 engages with the outer top of the honeycomb paperboard 2. The corner protectors 15 wrap the connection between the carton lid 4, the honeycomb paperboard 2, and the honeycomb paperboard 3, increasing the hardness of the corners.

[0039] Working principle: When using this carton, the honeycomb cardboard 1 2 can be aligned with the square groove 12 of the pallet bottom 1 and locked onto both sides of the pallet bottom 1. Then, the honeycomb cardboard 2 3 is aligned with the corresponding corner protector 13. The protruding locking blocks on both sides of the honeycomb cardboard 2 3 slide into the locking groove 14 of the corner protector 13 until the bottom end of the honeycomb cardboard 2 3 is locked and fixed in the square groove 12. This completes the quick installation of the carton and makes it convenient for users to use.

[0040] After the cardboard box is assembled, the user can place the items to be transported inside the assembled box, then align the box lid 4 with the tops of the honeycomb cardboard 1 2 and honeycomb cardboard 2 3 and snap it shut to close the box. Next, loop one end of the packing rope onto the hook block 6, and then pass it through the loop 7. As it passes through the loop 7, the abutment roller 8, under the elastic force of the leaf spring 9, will push against the rotating roller 11 and slide on the rope surface. This assists in the sliding of the packing rope while limiting its position, preventing it from falling to the ground and ensuring the packing rope adheres to the outside of the box. Finally, tie all the ropes passing through the loop 7 at the top of the box lid 4. This process only secures one side of the box. By tightening the ropes, the two honeycomb cardboard 1 2 are pressed against and snapped shut by the honeycomb cardboard 2 3, further strengthening the box's stability.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
