Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, and in particular to a corrugated cardboard box with a paper handle. Background Technology

[0002] Corrugated cardboard boxes with paper handles are widely used in e-commerce logistics, daily shopping, food packaging, and small appliance transportation due to their advantages such as low cost, recyclability, and light weight. However, in practical applications, the structural defects of traditional corrugated cardboard boxes with paper handles have gradually become apparent, leading to limitations in user experience and safety. Specific problems are as follows.

[0003] 1. Traditional paper handles are fixedly connected to the cardboard box. When the handle or its connecting part (such as the edge of the through hole) is damaged, the entire cardboard box will be unusable because it cannot be lifted. For example, if the handle of a corrugated cardboard box used to store clothes and toys in the home is broken, it will be difficult to move even if the box is intact, and it can only be discarded, which is both wasteful of resources and does not conform to the concept of environmental protection.

[0004] 2. In warehouses or home storage, traditional corrugated cardboard boxes with paper handles cannot be stacked tightly because the handles protrude from the top. The handles are easily crushed by the cardboard boxes above, or the protrusions cause the stack to be unstable, posing a risk of collapse. To solve this problem, warehouse staff often need to remove the handles before stacking. However, traditional handles and cardboard boxes are mostly integrated structures, and removing them can easily damage the main body of the cardboard box, making the cardboard box unusable and increasing packaging costs.

[0005] In conclusion, traditional corrugated cardboard boxes with paper handles have poor adaptability and cannot be adjusted for application scenarios involving the handling and stacking of light and heavy items. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a corrugated cardboard box with paper handles, solving the problem that traditional corrugated cardboard boxes with paper handles have poor adaptability and cannot be adjusted for application scenarios involving the handling and stacking of light and heavy objects.

[0030] This application provides a corrugated cardboard box with paper handles, which effectively solves the problem that traditional corrugated cardboard boxes with paper handles have poor adaptability and cannot be adjusted for application scenarios involving the handling and stacking of light and heavy objects.

[0031] Example

[0032] like Figure 1 - Figure 8 As shown, the technical solution in this application embodiment effectively solves the technical problem that traditional corrugated cardboard boxes with paper handles have poor adaptability and cannot be adjusted for application scenarios involving the handling and stacking of light and heavy objects. The overall idea is as follows:

[0033] To address the problems existing in the prior art, this utility model provides a corrugated cardboard box with paper handles, including a cardboard box body 1, two handle plates 3 are provided on the top of the cardboard box body 1, stiffening plates 2 are fixedly installed on the left and right sides of the two handle plates 3, and a top plate 5 is fixedly installed on the bottom of the four stiffening plates 2. Two side plates 7 are provided on the left and right sides of the cardboard box body 1, and the four side plates 7 are fixedly connected to the four top plates 5 respectively.

[0034] The reinforcing components are installed at the through holes of the handle plate 3 and the carton body 1, respectively, and are used to reinforce the through holes;

[0035] A connecting component is mounted on side panel 7 and is used to connect the reinforcing component.

[0036] Furthermore, the enhancement components include:

[0037] Three first carrying rings 4 are respectively inserted into the through holes on both sides of the carton body 1 and one of the handle plates 3. Two second carrying rings 14 are inserted into the through holes on the other side of the other handle plate 3 and the inner walls on both sides of the carton body 1. The three second carrying rings 14 are respectively connected to the three second carrying rings 14.

[0038] Furthermore, the connection components include:

[0039] Two adapter plates 8 are respectively located on the opposite side of the two first carrying rings 4 below. The two adapter plates 8 are fixedly connected to the two sets of side plates 7 respectively. Cover plates 9 are inserted into the opposite side of the two second carrying rings 14 below. Multiple connecting ropes 12 are fixedly installed at the bottom of the two adapter plates 8. Multiple limiting balls 13 are provided on the opposite side of the two cover plates 9. The other ends of the multiple connecting ropes 12 are fixedly connected to the multiple limiting balls 13 respectively.

[0040] Furthermore, both cover plates 9 have multiple limiting holes 10 on their side walls.

[0041] Furthermore, the inner diameter of the lower part of the limiting hole 10 is the same as the outer diameter of the limiting ball 13, and the inner diameter of the other parts of the limiting hole 10 is the same as the outer diameter of the connecting rope 12. The outer diameter of the connecting rope 12 is smaller than the outer diameter of the limiting ball 13.

[0042] Furthermore, multiple limiting posts 11 are fixedly installed on one side of each of the three first carrying rings 4, and the other side of the multiple limiting posts 11 passes through and engages with the two second carrying rings 14 respectively.

[0043] Furthermore, multiple locking blocks 15 are fixedly installed on the opposite side of both cover plates 9, and the multiple locking blocks 15 are respectively inserted into the notches at one end of multiple limiting posts 11.

[0044] Furthermore, a connecting plate 6 is fixedly installed between the tops of two adjacent top plates 5.

[0045] in:

[0046] Carton body 1: Made of corrugated cardboard, it has a rectangular hollow structure to hold the items to be packaged. The top is reserved for the installation position of the handle assembly, and the side walls have through holes for the installation of the reinforcement assembly.

[0047] Rib 2: One rib is fixedly installed on each of the left and right sides of each handle plate 3, for a total of four. It is made of rigid cardboard and is inclined to connect the handle plate 3 and the top plate 5. It is used to enhance the load-bearing capacity of the handle plate 3 and prevent the handle plate 3 from tearing due to excessive force.

[0048] Handle plate 3: There are two in total, symmetrically arranged on the top of the carton body 1. They are made of rigid cardboard and have a through hole in the middle for the hand to pass through for installing reinforcement components. They are the lifting parts that are directly subjected to force.

[0049] First carrying ring 4: There are three in total. They are made of plastic and have an oval structure. One side has a protrusion for insertion. They are respectively inserted into the outside of the through holes on both sides of the carton body 1 and the outside of the through hole of one of the handle plates 3, serving as the outer reinforcement structure at the through holes.

[0050] Top plate 5: One of each of the four stiffening plates 2 at the bottom is made of rigid cardboard and is horizontally set at the top edge of the carton body 1. It is connected to the stiffening plates 2 and the side plates 7 and plays a structural support role in connecting the top and bottom.

[0051] Connecting plate 6: It is fixedly installed between the tops of two adjacent top plates 5. It is made of flexible cardboard and is connected by adhesive. It is used to limit the separation angle of the top plates 5 and ensure the overall structural coordination of the handle assembly.

[0052] Side panels 7: Two are provided on each of the left and right sides of the carton body 1, for a total of four. They are set perpendicular to the top plate 5. One end is fixedly connected to the top plate 5, and the other end is connected to the side wall of the carton body 1 through a fold line. They can rotate synchronously with the top plate 5, thereby enhancing the structural stability of the top of the carton body 1.

[0053] Adapter plate 8: There are two in total. They are made of plastic and are respectively set on the opposite side of the first carrying ring 4 on both sides of the carton body 1. They are fixedly connected to the corresponding two sets of side plates 7 by adhesive bonding and serve as the connection medium between the connecting component and the side plate 7.

[0054] Cover plate 9: There are two in total. They are made of plastic and have a plate-like structure. They are inserted into the opposite side of the second carrying ring 14 on both sides of the carton body 1. They are used to close the inner opening of the second carrying ring 14 and to support the connecting structure of the connecting rope 12.

[0055] Limiting hole 10: It is opened on the side wall of the cover plate 9 and has a stepped hole structure. The inner diameter of the lower part is the same as the outer diameter of the limiting ball 13, and the inner diameter of the other parts is the same as the outer diameter of the connecting rope 12. When the limiting ball 13 is located at the lower end of the limiting hole 10, the connecting rope 12 is fixed to the cover plate 9. When the limiting ball 13 moves from the lower end to other parts, it can be disengaged from the limiting hole 10, thereby separating the connecting rope 12 from the cover plate 9.

[0056] Limiting post 11: Multiple of these are fixedly installed on one side of each first carrying ring 4. They are made of plastic, with one end fixed to the first carrying ring 4 and the other end passing through the second carrying ring 14 with a notch. Through the through-and-lock action, the first carrying ring 4 and the second carrying ring 14 are ensured not to separate after being connected, thus enhancing the overall integrity of the reinforced component.

[0057] Connecting rope 12: Made of plastic, it is fixedly installed at the bottom of each adapter plate 8 in a number matching the number of limit balls 13, and the other end is fixedly connected to the limit ball 13 for connecting the adapter plate 8 and the cover plate 9.

[0058] Limiting ball 13: Made of plastic, spherical structure, with a diameter larger than that of connecting rope 12, set on the opposite side of cover plate 9, and cooperates with the limiting hole 10 opened on the side wall of cover plate 9 to achieve connection or separation.

[0059] Second handle ring 14: There are three in total. They are made of the same material and have the same structure as the first handle ring 4. They are oval in shape and have grooves on the inside that match the protrusions of the first handle ring 4. They are respectively inserted into the through holes on both sides of the carton body 1 and the through hole on another handle plate 3, and are connected to the corresponding first handle ring 4 to form a double-layer reinforced structure to jointly bear the lifting force.

[0060] The locking block 15 is matched in number with the limiting post 11 and is fixedly installed on the opposite side of each cover plate 9. It is made of plastic and its shape is adapted to the notch at one end of the limiting post 11. By locking into the notch of the limiting post 11, the limiting part of the limiting post 11 is kept open, preventing it from closing and detaching from the second carrying ring 14 due to force.

[0061] Working principle:

[0062] First, when the items inside the cardboard box 1 are relatively light, you can lift the cardboard box 1 by holding the combination of the first carrying ring 4 and the second carrying ring 14 on the handle plate 3.

[0063] The second step is to stack the cardboard box bodies 1. If the items inside the cardboard box bodies 1 are heavy, the limiting ball 13 can be pushed down to move to the lower end of the limiting hole 10. Then the limiting ball 13 and the connecting rope 12 can be separated from the cover plate 9. Then the adapter plate 8, side plate 7, top plate 5, stiffening plate 2 and handle plate 3 can be removed from the cardboard box bodies 1, so that multiple cardboard box bodies 1 can be stacked.

[0064] Third, if the items stored in the main body 1 of the cardboard box are heavy or if the structural side panel 7, top panel 5, stiffening plate 2 and handle plate 3 are damaged, the main body 1 of the cardboard box needs to be moved. Based on the second step, the cover plate 9 can be pushed inward to separate the cover plate 9 from the second carrying ring 14. Then, the staff can use their hands to pass through the two sets of first carrying rings 4 and second carrying rings 14 to carry the box by hand, so as to avoid the entire box being scrapped due to damage to the handle part of the one-piece paper box.

[0065] Fourth step: Insert the locking block 15 into the notch of the limiting post 11 so that the limiting part at one end of the limiting post 11 is always in an open state, preventing the limiting part from closing and detaching from the second carrying ring 14.

[0066] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
