Technical Field
[0001] This utility model relates to the field of packaging boxes, specifically a special packaging box that prevents damage caused by excessive cutting when opening BOPP tape. Background Technology
[0002] In logistics transportation and warehousing management, BOPP (biaxially oriented polypropylene) tape is an important packaging material widely used for sealing, fixing and protecting various commodities. With the development of e-commerce, the demand for BOPP tape has increased dramatically, and the safety and convenience of its packaging and transportation have become the focus of industry attention. In order to improve packaging efficiency and protect goods, a variety of special packaging boxes for BOPP tape have appeared on the market.
[0003] However, in actual use, users often need to use a knife (such as a utility knife) to cut along the top seal of the box when opening it. However, due to factors such as operating technique, knife sharpness, or uneven thickness of the packaging material, the cutting depth is difficult to control precisely. If the cutting is too deep, it can easily damage the BOPP tape inside, causing problems such as cuts, breaks, or adhesion on the tape edges. Therefore, we propose a special packaging box to prevent damage caused by excessive cutting when opening the BOPP tape box. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a special packaging box to prevent damage caused by excessive cutting when opening BOPP tape. This solves the problem that in current practical use, users often need to use a knife (such as a utility knife) to cut along the top seal of the packaging box when opening it. However, due to factors such as operating method, knife sharpness, or uneven thickness of the packaging box material, it is difficult to accurately control the cutting depth. Once the cutting is too deep, it is easy to directly damage the BOPP tape inside, resulting in cuts, breaks, or adhesion on the tape edges.
[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a special packaging box is designed to prevent damage caused by excessive cutting when opening BOPP tape, including a packaging box body, the top of the packaging box body is provided with a box top plate, one end of the box top plate is bent and extended to the surface of the packaging box body to form an easy-tear part for tearing the packaging box.
[0006] Preferably, the top plate of the box is composed of two plates, which are fixed together by tape.
[0007] Preferably, the tear-resistant part consists of a trapezoidal plate formed by bending the top plate of the box and a trapezoidal groove on the surface of the packaging box.
[0008] Preferably, the trapezoidal plate is connected to the trapezoidal groove, and the position where the trapezoidal plate and the trapezoidal groove are connected is provided with multiple easy-tear holes.
[0009] Preferably, the trapezoidal plate has a semi-circular opening at the center of its edge.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model features an easy-tear section. When opening the box, the operator only needs to hold the semi-circular opening with their hand and pull upwards. Under the action of the pulling force, the easy-tear holes between the trapezoidal plate and the trapezoidal groove will break one after another, and the top plate of the box will open smoothly. No knives are needed throughout the process, which greatly improves the safety of the opening process and effectively eliminates the possibility of knives damaging the BOPP tape.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0016] Example 1: A special packaging box to prevent damage caused by excessive cutting when opening BOPP tape, see [link to example]. Figures 1 to 2 The package includes a box body 1, with a top plate 101 on top. One end of the top plate 101 is bent and extends to the surface of the box body 1, forming an easy-tear section for tearing the box. When an operator needs to open the box, they simply insert their finger into the semi-circular opening 202 on the top plate 101 and gently hold it in place. Then, an upward pulling force is applied. Under the action of the pulling force, the easy-tear hole 201 between the trapezoidal plate 2 and the trapezoidal groove 203 begins to bear the force. Under tension, the easy-tear hole 201 will break in sequence. As the easy-tear hole 201 gradually breaks, the connection between the trapezoidal plate 2 and the trapezoidal groove 203 gradually weakens. Under the continuous action of the lifting force, the top plate 101 of the box slowly lifts upward along the path of the breakage of the easy-tear hole 201. As the lifting action continues, the connection between the top plate 101 of the box and the side plate of the box is continuously reduced. Finally, the top plate 101 of the box can be opened smoothly from the packaging box, exposing the BOPP tape loaded inside.
[0017] For details, see Figures 1 to 2The top panel 101 of the box is composed of two panels, which are fixed together by tape.
[0018] For more details, see Figures 1 to 2 The easy-tear section consists of a trapezoidal plate 2 formed by bending the top plate 101 of the box and a trapezoidal groove 203 on the surface of the packaging box 1.
[0019] Further, see Figures 1 to 2 The trapezoidal plate 2 is connected to the trapezoidal groove 203, and multiple easy-tear holes 201 are provided at the connection position between the trapezoidal plate 2 and the trapezoidal groove 203.
[0020] It is worth noting that, see Figures 1 to 2 A semi-circular opening 202 is provided at the middle of the edge of the trapezoidal plate 2.
[0021] When using a special packaging box designed to prevent damage caused by excessively deep cuts when opening BOPP tape, the operator simply inserts their finger into the semi-circular opening 202 on the top panel 101 of the box and gently holds it in place. Then, an upward pulling force is applied. Under the action of the pulling force, the easy-tear hole 201 between the trapezoidal plate 2 and the trapezoidal groove 203 begins to bear the tension. The easy-tear hole 201 will break one after another. As the easy-tear hole 201 gradually breaks, the connection between the trapezoidal plate 2 and the trapezoidal groove 203 gradually weakens. Under the continuous action of the pulling force, the top panel 101 of the box slowly tilts upward along the path of the broken easy-tear hole 201. As the pulling action continues, the connection between the top panel 101 of the box and the side panel of the box is continuously reduced. Finally, the top panel 101 of the box can be smoothly opened from the packaging box, exposing the BOPP tape loaded inside.
