Detailed Description

Examples

Fig. 1 is the structural schematic diagram of the high-strength thermal insulation carton embodiment of the utility model, fig. 2 is the utility model relates to a bottom structural schematic diagram of high-strength thermal insulation carton embodiment. As shown in the figure, the high-strength heat preservation carton comprises a carton body 1 and a carton cover 2, wherein the carton cover 2 is positioned above the carton body 1 and covers the carton body 1. The box body 1 is closely contacted with the box cover 2, and the adhesive tape can be wound at the connecting surface of the box body 1 and the box cover 2 so as to improve the heat preservation effect of the carton and the connecting strength between the box body 1 and the box cover 2.

Fig. 4 is a schematic structural view of a corner protector 3 according to an embodiment of the present invention. As shown in the figure, the edges of the side surface and the bottom surface of the box body 1 are provided with angle protectors 3, and the edges of the box cover 2 are provided with the angle protectors 3. The corner protector 3 comprises a guard 15, the guard 15 being of cardboard. The protector sheet 15 has a fold line 13 in the middle portion along the longitudinal direction thereof, and the fold line 13 extends along the entire length of the protector sheet 15. The side of the cover sheet 15 is provided with a notch 14, and the bottom of the notch 14 is located on the crease line 13. In this embodiment, the protective plate 15 is provided with two notches 14, and one corner protector 3 is adopted to cover half of the box body 1 or the box cover 2.
