[0036] The present invention includes the following embodiments.

[0037] As Figures 1 to 3As shown, the present utility model provides a carton 100 facilitating the loading and unloading of heavy objects, including an independent first cardboard 10 and a second cardboard 20. The first cardboard 10 and the second cardboard 20 are two separate components. In this embodiment, both the first cardboard 10 and the second cardboard 20 are made of BC corrugated paper.

[0038] Among them, the first cardboard 10 includes a plurality of paper walls 30 connected together. After the plurality of paper walls 30 of the first cardboard 20 are folded, they can form the bottom wall and four side walls of the box body. Among the two relatively arranged side walls, each side wall is formed by at least two parts being snap-connected together to form a combined wall 50, and the combined wall 50 can be disassembled. As Figure 3 shown, the plurality of paper walls 30 of the first cardboard 10 form the bottom wall, the front and rear side walls arranged oppositely, and the left and right side walls of the box body. The front side wall among them is formed by two separately arranged paper walls being snap-connected together to form a combined wall 50, and the rear side wall is also formed by two separately arranged paper walls being snap-connected together to form a combined wall 50. Because the combined wall 50 is formed by two separately arranged paper walls being snap-connected, it can be disassembled and is very convenient to disassemble.

[0039] The second cardboard 20 of the present utility model includes a plurality of paper walls 40 connected together. After the plurality of paper walls 40 of the second cardboard 20 are folded, they can cover the outside of the bottom wall and the combined wall 50 surrounded by the first cardboard 10. As Figure 3 shown, after the plurality of paper walls 40 of the second cardboard 20 are folded, they cover the outside of the bottom wall, the front side wall, and the rear side wall surrounded by the first cardboard 10.

[0040] Preferably, on the sides of the first side wall 32 and the second side wall 33 of the first cardboard 10 away from the first bottom wall 31, there are respectively provided a foldable first top wall 34 and a second top wall 35. After the first top wall 34 and the second top wall 35 are folded, they together form the top wall of the box body to protect the top of the items in the box.

[0041] When loading items into the carton 100 of the present utility model, first place the first cardboard 10 and the second cardboard 20 crosswise, with the first cardboard 10 above the second cardboard 20. Then move the item onto the bottom wall of the first cardboard 10, and then fold the other paper walls of the first cardboard 10 to surround the item on all sides, forming the front, back, left, and right side walls of the box. The front and back side walls are formed by the snap connection of two folded paper walls. Then fold the second cardboard 20 to wrap the front and back side walls of the first cardboard 10 to prevent the front and back side walls formed by the first cardboard 10 from coming loose. Then fold the first top wall 34 and the second top wall 35 to cover the top of the object, and then it can be packed. When taking out the item, first remove the outer packaging of the box, then open the second cardboard 20 to expose the front and back side walls of the first cardboard 20. Then loosen the snap connection of the front and back side walls of the first cardboard 20, and then the entire first cardboard 10 will automatically spread out to completely expose the item, so that the item can be easily taken away. That is, the carton 100 of the present utility model is very convenient for loading and unloading heavy items, without having to put in or take out from the top of the box. Especially when taking out heavy items, just open the side wall of the box, which is very practical.

[0042] In this embodiment, as Figure 3 shown, when assembling the carton 100, first place the first cardboard 10 and the second cardboard 20 crosswise, with the first cardboard 10 above the second cardboard 20. In this way, the bottom of the entire box is composed of the bottom paper walls of the first cardboard 10 and the second cardboard 20 stacked together, which not only improves the support strength of the bottom of the box, but also, since the bottom is directly stacked, there is no need for bottom sealing, and the use of packing tape is also reduced.

[0043] Preferably, on at least two parts forming the combined wall 50, there are respectively provided a protrusion 53 and a notch 54 that can be mutually engaged. As Figure 1 and Figure 3 shown, the protrusion 53 and the notch 54 on the paper wall of the first cardboard 10 form a snap structure, so that two paper walls on the first cardboard 10 are engaged together to form the combined wall 50. The snap structure of the protrusion 53 and the notch 54 is simple and easy to implement.

[0044] Specifically, referring to Figure 3 and Figure 4, in this embodiment, the multiple paper walls 30 of the first cardboard 10 include a first bottom wall 31, a first side wall 32 and a second side wall 33 that are connected to two opposite sides of the first bottom wall 31 and can be folded. First engaging walls 321 and second engaging walls 322 that can be folded are respectively arranged on two opposite sides of the first side wall 32, and third engaging walls 331 and fourth engaging walls 332 that can be folded are respectively arranged on two opposite sides of the second side wall 33. The first engaging wall 321 can be engaged with the third engaging wall 331 to form a first combined wall 51, and the second engaging wall 322 can be engaged with the fourth engaging wall 332 to form a second combined wall 52. In this embodiment, after the first side wall 32 and the second side wall 33 are respectively folded relative to the first bottom wall 31, they form the left side wall and the right side wall of the box body. The first engaging wall 321 at the lower end and the second engaging wall 322 at the upper end of the first side wall 32 can be folded relative to the first side wall 32, and the third engaging wall 331 at the lower end and the fourth engaging wall 332 at the upper end of the second side wall 33 can be folded relative to the second side wall 33. Since the first engaging wall 321 and the third engaging wall 331 are located on the same side of the first bottom wall 31, the first engaging wall 321 and the third engaging wall 331 can be engaged together to form the front side wall of the box body; similarly, since the second engaging wall 322 and the fourth engaging wall 332 are located on the same side of the first bottom wall 31, the second engaging wall 322 and the fourth engaging wall 332 can be engaged together to form the rear side wall of the box body. That is, in this embodiment, the front and rear side walls of the box body are both combined walls and can be disassembled.

[0045] In this embodiment, the first engaging wall 321, the second engaging wall 322, the third engaging wall 331, and the fourth engaging wall 332 are all provided with the protrusions 53 and the notches 54 so that the first engaging wall 321 and the third engaging wall 331 are mutually engaged, and the second engaging wall 322 and the fourth engaging wall 332 are mutually engaged. As Figure 3 shown, in the front combined wall of the box body, it is formed by the mutual engagement of the protrusions 53 and the notches 54 on the first engaging wall 321 and the third engaging wall 331 respectively; in the rear combined wall of the box body, it is formed by the mutual engagement of the protrusions 53 and the notches 54 on the third engaging wall 322 and the fourth engaging wall 332 respectively. In this way, when assembling and disassembling the front and rear side walls of the box body, it is very simple and fast.

[0046] Refer to Figure 3 and Figure 5, the multiple paper walls 40 of the second cardboard 20 in this embodiment include a second bottom wall 41, a fifth side wall 42 and a sixth side wall 43 which are connected to two opposite sides of the second bottom wall 41 and can be folded. The second bottom wall 42 can cover the first bottom wall 31, and the fifth side wall 42 and the sixth side wall 43 can respectively cover the first combined wall 51 and the second combined wall 52. Plug-in walls 44 are provided on both the fifth side wall 42 and the sixth side wall 43 and can be inserted into and clamped in the box body. The second bottom wall 41 is attached to the lower part of the first bottom wall 31, and the second bottom wall 41 and the first bottom wall 31 are superposed together to jointly form the bottom wall of the box body, that is, the bottom of the box body in this embodiment is a double-layer structure.

[0047] Meanwhile, the fifth side wall 42 and the sixth side wall 43 of the second cardboard 20 are respectively attached to the front side wall and the rear side wall of the box body surrounded by the first cardboard 10, so that the two combined walls can be covered and surrounded during the assembly process, preventing the front side wall and the rear side wall surrounded by the first cardboard 10 from loosening and ensuring the firmness of the box body packaging.

[0048] The plug-in walls 44 on the fifth side wall 42 and the sixth side wall 43 are used to be inserted into and clamped in the box body surrounded by the first cardboard 10, so that the second cardboard 20 and the first cardboard 10 are firmly connected and combined.

[0049] Specifically, the plug-in wall 44 includes a folded top wall 441 provided on the side of the fifth side wall 42 or the sixth side wall 43 away from the second bottom wall 42, and clamping ears 442 provided on two opposite sides of the folded top wall 441 and can be folded. After the two folded top walls 441 are folded around the front and rear combined walls of the box body, they can enclose the top wall of the box body, and the clamping ears 442 can abut against the inner walls of the front and rear combined walls of the box body to prevent the second cardboard 20 from detaching from the first cardboard 10.

[0050] Preferably, referring to Figure 4 and Figure 5 , plugs 70 are provided on the clamping ears 442, and sockets 60 are respectively provided at the joints of the first side wall 32 with the first engaging wall 321 and the second engaging wall 322, and at the joints of the second side wall 33 with the third engaging wall 331 and the fourth engaging wall 332. The plugs 70 can be inserted into the sockets 60. That is, during the process of combining the first cardboard 10 and the second cardboard 20 into a box body, the plugs 70 on the clamping ears 442 of the second cardboard 20 can be inserted into the sockets 60 on the first cardboard 10. In this way, in the assembled carton, the clamping ears 442 of the second cardboard 20 can not only be clamped in the box body, but also be inserted into the sockets 60 of the first cardboard 10, making the assembly more firm.

[0051] Further, support bumps 80 are provided on one side of the first engaging wall 321, the second engaging wall 322 adjacent to the first top wall 34, one side of the third engaging wall 331, and the fourth engaging wall 332 adjacent to the second top wall 35. After the cardboard box 100 is assembled, the support bumps 80 can support and hold the folded first top wall 34 and the second top wall 35 of the first cardboard 10, preventing the first top wall 34 and the second top wall 35 from collapsing inside the box body.

[0052] Preferably, handle holes 90 are provided on both the fifth side wall 42 and the sixth side wall 43. The provision of the handle holes 90 facilitates lifting the assembled box body.

[0053] Further, the handle hole 90 is formed by intermittently processing the paper wall to form a continuous breaking line, and then folding the paper wall inward at the continuous breaking line to fracture and fold this part of the paper wall, which can achieve the effect of lifting the cardboard box without cutting hands.

[0054] As a way, the assembly process of the cardboard box 100 of the present utility model is as follows:

[0055] 1. First, place the first cardboard 10 and the second cardboard 20 crosswise, with the first cardboard 10 above the second cardboard 20, and then place heavy items on the first bottom wall 31 of the first cardboard 10. As Figure 3 shown, subsequently, turn up the first side wall 32 and the second side wall 33 of the first cardboard 10 to form the left side wall and the right side wall of the box body. Turn the first engaging wall 321 on the first side wall 32 to the right, turn the third engaging wall 331 on the second side wall 33 to the left, and lock and engage the convex blocks 53 and the notches 54 of the first engaging wall 321 and the third engaging wall 331 with each other to form the front side wall of the box body; turn the second engaging wall 322 on the first side wall 32 to the right, turn the fourth engaging wall 332 on the second side wall 33 to the left, and lock and engage the convex blocks 53 and the notches 54 of the second engaging wall 322 and the fourth engaging wall 332 with each other to form the rear side wall of the box body.

[0056] 2. Subsequently, turn up the fifth side wall 42 and the sixth side wall 43 of the second cardboard 20 and cover them outside the front and rear side walls of the box body to form the double-layer front and rear side walls of the box body; then turn up the folding top wall 441 of the insertion wall 44 of the second cardboard 20 and fold it into the box body, and fold and lock it in the box body through the lugs 442, as Figure 6 shown.

[0057] 3. Finally, turn the first top wall 34 and the second top wall 35 of the first cardboard 10 relative to each other and fold them to cover the top of the box body, as Figure 7 shown, and then pack.

[0058] The opening process of the cardboard box 100 of the present utility model is as follows:

[0059] First, open the first top wall 34 and the second top wall 35, then open the insertion wall 44 outward, and then directly pat open the engaging structures on the front and rear side walls of the first cardboard 10. The box can then be directly dispersed and opened, and subsequently, the heavy product contained therein can be taken out. Therefore, when the carton 100 of the present utility model is used for packaging heavy products, it is more convenient both when taking out and placing the products.
