Detailed ways

The packaging box of the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. the

As shown in Figures 1 to 4, the packaging box of the present utility model is composed of an integrated foamed polyethylene (EPE) sheet 10, and the foamed polyethylene sheet 10 includes a first side plate 11 , the second side plate 12, the third side plate 13, the fourth side plate 14, the bottom plate 15 and the cover plate 16; 14 is oppositely arranged, the first side plate 11, the second side plate 12, the third side plate 13 and the cover plate 16 respectively have an inner end and a plurality of outer ends, and the fourth side plate 14 has two opposite inner ends With the two opposite outer ends, the inner ends of the first side plate 11, the second side plate 12 and the third side plate 13 and one of the inner ends of the fourth side plate 14 are respectively connected around the bottom plate 15. Another inner end of the four side plates 14 is also connected with the inner end of the cover plate 16, the first side plate 11, the second side plate 12, the third side plate 13, the fourth side plate 14 and the outer surface of the cover plate 16. The end is provided with a locking structure 100 which cooperates with each other. the

Between the inner ends of the first side plate 11 , the second side plate 12 and the third side plate 13 and one of the inner ends of the fourth side plate 14 and the surroundings of the bottom plate 15 and the other side of the fourth side plate 14 The inner end and the inner end of the cover plate 16 are respectively connected by a half-cut board 101, and the half-cut board 101 is cut by a half tangent (the depth of the tangent slit is 2/3 of the thickness of the sheet, and 1/3 is reserved) After the EPE sheet, it is easier to peel off the cut EPE layer and keep the uncut part. The width and thickness of the half-cut board 101 are 1/3 of the thickness of the foamed polyethylene sheet 10, and the whole sheet is foamed. After the polyethylene sheet 10 is folded and used, the area inside the dotted line box is the use area of the packaging box (as shown in FIG. 1 ). the

The thickness of the half-cut board 101 can be one-third of the thickness of the first side board 11, the second side board 12, the third side board 13, the fourth side board 14, the bottom board 15 or the cover board 16, and the locking structure 100 Including convex button structures 111, 121, 131, 161 and concave button structures 112, 122, 132, 142, 162, the convex button structures 111, 121, 131, 161 and corresponding concave button structures 112, 122, 132, 142 , 162 can engage with each other. the

Each convex buckle structure 111, 121, 131, 161 has two opposite inclined sides and a top surface connecting the two inclined sides, and each inclined side protrudes outward near the top surface at an angle of 15~ 30 degrees (as shown in Figure 2); each concave buckle structure 112, 122, 132, 142, 162 has two opposite inclined side walls, each inclined side wall includes an inner surface and a top surface connected to the side, The inclination angle of the inner surface protruding outward near the top surface is 15-30 degrees (as shown in Figure 2). This structure makes the mortise joints between the plates increase the locking force of the plates. the

The locking structure 100 on the outer end side of the first side plate 11 and the third side plate 13 corresponds to the locking structure 100 on the outer end side of the second side plate 12 and the fourth side plate 14 respectively; The locking structure 100 on the outer end of the board 16 corresponds to the locking structure 100 on the top surface of the outer end of the first side plate 11 , the second side plate 12 , and the third side plate 13 respectively. The packaging box using this technology can be easily three-dimensionally formed only by the locking structure of the box piece itself during packaging, and the operation is simple, fast and efficient. The waste after packaging and use can be disassembled into sheets for easy recycling , transportation, saving costs. The whole sheet is formed into three dimensions, and the operation is simple, fast and efficient. the

The packaging box is made of expanded polyethylene (EPE) material bonded by multi-layer sheets. After the EPE material is subjected to external impact and vibration, it can cushion and absorb shock without cracking. It protects the fruit inside well; in actual use, EPE materials of different thicknesses can be selected to make processing containers according to actual needs to meet the transportation and packaging requirements of fruits; the waste after packaging can be disassembled into flakes, which is convenient for recycling. Shipping saves costs. the
