Description

Technical Field

[0001] This invention relates to the field of packaging box technology, and in particular to a crush-resistant packaging box. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as: cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, PVC boxes, etc. Currently, cardboard boxes are the most common type of packaging box on the market. However, cardboard boxes are made of cardboard, which has limited pressure resistance and is easily deformed by compression.

[0003] Chinese Patent CN219313301U discloses a crush-resistant packaging box, including a box body comprising a surface cardboard board, a reinforcing cardboard board, and a base cardboard board. These three boards are arranged sequentially from top to bottom within the box body. A cover plate is positioned on top of the box body. A supporting transverse plate is located around the inner wall of the box body, with two connecting plates on one side. This crush-resistant packaging box utilizes a multi-layered structure to enhance its strength. The internal reinforcing cardboard boards provide triangular support for the cardboard body, achieving good stability and increasing its resistance to compression. The positioning and stabilizing blocks and grooves facilitate installation of the support base, improving its positioning effectiveness.

[0004] However, the device still has shortcomings: the packaging box is composed of a surface cardboard, a reinforcing cardboard and a base cardboard. During production and processing, it cannot be completed on a single piece of cardboard through simple operations such as stamping and cutting. It needs to be assembled separately, which is more troublesome. Furthermore, the split structure is also troublesome during transportation. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background art by proposing a crush-resistant packaging box.

[0006] The technical solution of the present invention is: a crush-resistant packaging box, comprising a box body, a bottom plate A, a bottom plate B, and a pad.

[0007] The box body includes two opposing side panels A and two opposing side panels B. Adjacent side panels A and B are perpendicularly connected, and a top cover plate is provided on side panel B and rotatably connected thereto. A bottom plate A is located at the bottom of side panel A and integrally connected to it. The bottom plate A is integrally connected to a support plate A. A limiting hole is provided between the bottom plate A and the support plate A, and the end of the support plate A away from the bottom plate A abuts against the top cover plate.

[0008] A base plate B is located at the bottom of the surrounding panel B. The end of the base plate B furthest from the surrounding panel B is integrally connected to a support plate B. The support plate B passes through a limiting hole and is inserted into the box body. The support plate B is slidably connected to the support plate A, and the support plate B and support plate A are perpendicular to each other. A pad is integrally set on the base plate B and is rotatably connected to the base plate B. The pad is inserted into the box body and fits against the corresponding side of the base plate A.

[0009] Preferably, slots are provided on the side of the two upper cover plates that are close to each other, the two slots are connected, and the end of the support plate A away from the bottom plate A is integrally connected to the lifting plate, which passes through the two slots and is slidably connected to them.

[0010] Preferably, the two upper cover plates are provided with mutually cooperating low steps on the side that are close to each other, and mutually cooperating adhesive components are provided in the low steps.

[0011] Preferably, the enclosure B is provided with an air hole communicating with the inside of the box, the enclosure B is provided with a guide frame outside the air hole, the guide frame is provided with a through hole A communicating with the air hole inside the guide frame, the inner side of the guide frame is provided with a sealing plate that is slidably connected to it, the sealing plate is provided with a through hole B, and the through hole B is correspondingly connected to the through hole A on the corresponding side.

[0012] Preferably, ventilation hole A is provided on support plate A, and ventilation hole B is provided on support plate B. Both ventilation hole A and ventilation hole B are connected to air holes.

[0013] Preferably, protective films are provided on the outer surfaces of enclosure A, enclosure B, top cover plate, bottom plate A, and bottom plate B.

[0014] On the other hand, the present invention also proposes a method for folding and packaging a crush-resistant packaging box, comprising the following steps:

[0015] S1. Lay the processed packaging cardboard flat, and press the outer edges of the side panels A and B at both ends of the cardboard together. At this time, side panels A and B form an initial box frame.

[0016] S2. Fold the support plates A on both sides of the bottom plate A so that they are perpendicular to the corresponding side bottom plate A. Then flip the two sides of the bottom plate A and insert the support plates A into the box frame so that the bottom plate A is flush with the bottom opening of the box frame. At this time, the two sides of the support plates A are horizontally mounted in the box frame and support the two sides of the box frame B, thereby improving the impact resistance of the two sides of the box frame B.

[0017] S3. Fold the support plate B and pad on both sides of the bottom plate B so that they are perpendicular to the corresponding side bottom plate B. Then flip the two sides of the bottom plate B and pass the support plate B and pad through the inner side of the limiting hole between the support plate A and the bottom plate A until the support plate B is perpendicular to the support plate A. At this time, the bottom plate B is in contact with the bottom of the box frame, and the support plate B supports the other two side plates of the box frame, improving the impact resistance of the two side plates A.

[0018] S4. Continue to flip the pad so that it fits against the base plate A. At this time, the pad and the corresponding base plate B clamp and engage the base plate A.

[0019] S5. Place the products to be packaged into the corresponding side compartments, pressing the products against the pads. This pressure increases as the products are stacked, causing the pads and base plate A to adhere more tightly. After all products are in place, close the top covers on both sides and seal the package.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] By setting a support plate A at the bottom of base plate A, and setting a limiting hole at the connection between support plate A and base plate A, and setting a support plate B at the bottom of base plate B, support plate B is inserted into the packaging box after being folded and inserted along the limiting hole. At this time, support plate A and support plate B form a cross structure inside the packaging box, supporting the four sides of the packaging box from the middle, thereby improving the packaging box's resistance to compression. At the same time, a pad is set on base plate B. After being folded, the pad is attached to base plate A, and base plate A is clamped by the pad and base plate B. At this time, the bottom of the entire packaging box does not need to be sealed with tape. Moreover, this fit structure becomes more solid as the pressure of the product increases. The multi-layered structure of the bottom of the packaging box further improves its bottom load-bearing capacity and its ability to prevent deformation. Attached Figure Description

[0027] Example 1

[0028] like Figures 1-9As shown, the present invention proposes an anti-crush packaging box, which includes a box body, a bottom plate A6, a bottom plate B7, and a pad 9.

[0029] The box body includes two opposing side panels A1 and two opposing side panels B2. Adjacent side panels A1 and B2 are perpendicularly connected. A top cover plate 3 is provided on side panel B2 and is rotatably connected to it. A bottom plate A6 is provided at the bottom of side panel A1 and integrally connected to it. The bottom plate A6 is integrally connected to a support plate A61. A limiting hole 601 is provided between the bottom plate A6 and the support plate A61, and the end of the support plate A61 away from the bottom plate A6 abuts against the top cover plate 3.

[0030] A base plate B7 is located at the bottom of the surrounding panel B2. The end of the base plate B7 furthest from the surrounding panel B2 is integrally connected to a support plate B8. The support plate B8 passes through a limiting hole 601 and is inserted into the box body. The support plate B8 is slidably connected to the support plate A61, and the support plate B8 and support plate A61 are perpendicular to each other. A pad 9 is integrally mounted on the base plate B7 and is rotatably connected to the base plate B7. The pad 9 is inserted into the box body and fits against the corresponding side base plate A6. Protective films are provided on the outer surfaces of the surrounding panels A1, B2, top cover 3, base plate A6, and base plate B7.

[0031] In this embodiment, the initial state of the packaging box is a complete cardboard structure. The cardboard is punched with slots 301, limiting holes 601 and limiting grooves 801 using a punching machine. The original support plate B8 is cut into a structure of support plate B8 and pad plate 9 using a cutter. Both the pad plate 9 and the support plate B8 can be folded and flipped. The preparation process is simple, convenient and efficient, and easy to assemble. At the same time, the stamping process produces less waste, which improves the utilization rate of the sheet material. The cut and stamped cardboard is stacked for easy transportation. In actual use, the cardboard can be quickly folded into a complete packaging box, which is simple and convenient to operate.

[0032] Example 2

[0033] like Figures 1-9 As shown, the present invention proposes an anti-crush packaging box. Compared with Embodiment 1, slots 301 are provided on the sides of the two upper cover plates 3 that are close to each other. The slots 301 on both sides are connected. The end of the support plate A61 away from the bottom plate A6 is integrally connected to the lifting plate 62. The lifting plate 62 passes through the slots 301 on both sides and is slidably connected to them. The sides of the two upper cover plates 3 that are close to each other are provided with mutually cooperating low steps, and mutually cooperating adhesive components 302 are provided in the low steps.

[0034] In this embodiment, the packaging box usually needs to be easy to hold and carry when in actual use. Ordinary packaging boxes have holes on both side panels, and when transferring and carrying them, it is necessary to lift them with both hands, which is time-consuming and laborious. In addition, it is impossible to hold other objects in this state. At this time, the packaging box can be picked up by grasping the lifting plate 62 with one hand.

[0035] Example 3

[0036] like Figures 1-9 As shown, the present invention proposes an anti-crush packaging box. Compared with Embodiment 1, the surrounding plate B2 is provided with an air hole 201 communicating with the box body. A guide frame 4 is provided on the outside of the surrounding plate B2, covering the outside of the air hole 201. The guide frame 4 is provided with a through hole A401 communicating with the air hole 201. A sealing plate 5 is provided on the inner side of the guide frame 4 and slidably connected thereto. The sealing plate 5 is provided with a through hole B501, which is correspondingly connected to the through hole A401. A ventilation hole A602 is provided on the support plate A61, and a ventilation hole B802 is provided on the support plate B8. Both the ventilation holes A602 and B802 are connected to the air hole 201.

[0037] In this embodiment, for the products inside the packaging box, some need to maintain a sealed environment, while others need to maintain a ventilated environment. When ventilation is required inside the packaging box, the sealing plate 5 can be slid horizontally to connect its through hole B501 with its through hole A401. At this time, outside air can enter the packaging box through one through hole B501, flow through the inside of the packaging box, and then exit through the other through hole B501, forming an air-circulating environment. When ventilation is not required, the sealing plates 5 on both sides can be slid to disconnect the through holes B501 and A401. The operation is simple and convenient, and it gives the packaging box different functions of packing.

[0038] Example 4

[0039] like Figures 4-9 As shown, the present invention proposes an anti-crush packaging box, the folding and packaging operation method of which includes the following steps:

[0040] S1. Lay the processed packaging cardboard flat, and press the outer edges of the side panels A1 and B2 at both ends of the cardboard together. At this time, side panels A1 and B2 form an initial box frame.

[0041] S2. Fold the support plates A61 on both sides of the bottom plate A6 so that they are perpendicular to the corresponding side bottom plate A6. Then flip the two sides of the bottom plate A6 and insert the support plates A61 into the box frame so that the bottom plate A6 is flush with the bottom opening of the box frame. At this time, the two side support plates A61 are horizontally mounted in the box frame and support the two side panels B2 of the box frame, thereby improving the impact resistance of the two side panels B2.

[0042] S3. Fold the support plate B8 and pad 9 on both sides of the bottom plate B7 so that they are perpendicular to the corresponding side bottom plate B7. Then flip the two sides of the bottom plate B7 and pass the support plate B8 and pad 9 through the inner side of the limiting hole 601 between the support plate A61 and the bottom plate A6 until the support plate B8 is perpendicular to the support plate A61. At this time, the bottom plate B7 is in contact with the bottom of the box frame, and the support plate B8 supports the other two side plates of the box frame, improving the impact resistance of the two side plates A1.

[0043] S4. Continue to flip the pad 9 so that the pad 9 fits against the base plate A6. At this time, the pad 9 and the corresponding base plate B7 clamp and engage the base plate A6.

[0044] S5. Place the product to be packaged into the corresponding side compartment. The product presses down on the pad 9, and the pressure increases as the product is stacked, making the pad 9 and the base plate A6 fit tighter and tighter. After the product is placed, cover the two side upper cover plates 3 and seal it.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
