Description

Technical Field

[0001] The utility model relates to a corrugated paper box, in particular to a high-strength paper box. Background Art

[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and the usage has always been the first among all kinds of packaging products. Including calcium plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, becoming the main force of transport packaging. In addition to protecting goods and facilitating storage and transportation, it also plays a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products, which are beneficial to the environment and convenient for loading and unloading.

[0003] However, due to the average bending strength of corrugated paperboard, the strength of corrugated boxes is also average. Therefore, during transportation and use, when corrugated boxes are bumped, they are easily deformed. This will not only cause damage to the corrugated box itself, but also affect the goods packaged in it. Especially in the express delivery industry, the strength of the corrugated box will directly affect the probability of damage to the express delivery. For this reason, the corrugated box production industry urgently needs to solve the current problem of insufficient strength of corrugated boxes. Summary of the invention

[0004] The utility model provides a high-strength paper box, which solves the problem of insufficient strength of corrugated paper boxes in the prior art.

[0006] The utility model can be produced by conventional production processes, specifically: cardboard is obtained by cutting process, and then a folding line is pressed on the cardboard by a pressing process, and finally a finished product is obtained by slotting. The finished product is the unfolded state of the carton. It is necessary to first bend the four side panels into a head-to-tail butt-jointed state, and glue and fix the connecting piece to the inner surface of the fourth side panel, and then start to bend all the folding areas in sequence, fold inward along the inward folding line, and fold outward along the outward folding line. After the folding is completed, it is glued or fixed by nailing the box nails, or other fixing methods, and finally all the cover plates are turned inward and closed. It should be noted that the upper and lower cover plates corresponding to the second side panel and the fourth side panel are located on the outside, and the upper and lower cover plates corresponding to the first side panel and the third side panel are located on the inside. After the utility model is folded into a box body, because the internal space is occupied by the cardboard ribs generated by the inward folding of the folding area, under the premise of the same external dimensions, the available storage space inside the utility model will be reduced compared with the conventional box body, but due to the strengthening effect of the cardboard ribs, the overall anti-bending and anti-deformation performance of the utility model has been greatly improved, and the overall strength is improved.

[0007] Furthermore, at least two annular cable ties are included, and the annular cable ties are arranged around the first side plate, the second side plate, the third side plate and the fourth side plate, so that all the first folding areas and all the second folding areas are in a folded state.

[0008] Therefore, compared with the prior art, the present invention has the following characteristics: 1. After the present invention is folded into a box, the internal space is occupied by the cardboard ribs generated by the inward folding of the folding area, resulting in a reduction in the internal available storage space of the present invention compared with a conventional box under the premise of the same outer dimensions. However, due to the reinforcing effect of the cardboard ribs, the overall anti-bending and anti-deformation performance of the present invention is greatly improved, and the overall strength is improved.

[0017] The present embodiment can be produced by conventional production processes, specifically: cardboard is obtained by cutting, folding lines are pressed on the cardboard by pressing lines, and finally slotting is performed to obtain the finished product. The finished product is the unfolded state of the carton.

[0018] The spacing between any inward-turning fold line and outward-turning fold line in the same folding area is between 10 and 40 mm. This distance is approximately equal to the protruding height of the cardboard ribs. If the value is too small, it will greatly increase the difficulty of bending the sheet. If the value is too large, the cardboard ribs themselves will occupy too much storage space and increase instability.

[0019] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
