3. All joints of the carton are laminated by using a paperboard surface and a surface, and are bonded by using hot melt adhesive. The condition that a plurality of positions of the conventional carton are that the end faces of the paper boards are butted with the end faces and a gap is inevitably formed does not exist. This results in a greatly improved closure of the carton.
4. The carton has 9 paper boards which are overlapped and bonded, wherein 8 paper boards are overlapped with each other in a face-to-face mode, and one paper board is folded by 90 degrees and is overlapped with the plane of the other paper board after being extruded with the end face of the other paper board (refer to fig. 8). The cardboard has certain deformation after receiving the extrusion, and this deformation can let the junction closure better.
5. The integral top cover of the carton is overlapped and bonded on the four vertical surfaces, so that the closure of the carton is enhanced, and the stability of the carton is further enhanced. And the bearing capacity can be further enhanced due to the improvement of the stability.
