Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, in particular to a corrugated paperboard which is convenient for stacking. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of wavy core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. It is mainly used to make cartons, carton cores and other packaging materials for fragile goods.

[0003] When corrugated cardboard is currently folded into cartons, it is necessary to glue the head and tail together with adhesives such as glue. This is generally achieved on the production line through automated devices, which is inconvenient to use in some temporary sites and requires a certain amount of time to wait for the glue to be firmly attached. In addition, empty cartons take up a lot of transportation space and are generally transported in a flat state of corrugated cardboard. However, the surface is relatively smooth, and when stacked to a certain height during transportation, it is very easy to collapse under the action of external forces, which may even endanger the lives of relevant personnel in severe cases. Therefore, we propose a corrugated cardboard that is easy to stack to solve the above problems. Utility Model Content

Furthermore, due to the trapezoidal structure of the trapezoidal plastic box 6, the upper end of the trapezoidal plastic box 6 on the lower side can be inserted into the interior of the trapezoidal plastic box 6 on the upper side, thereby achieving an all-round limiting relationship through the snap-fit ​​relationship between the trapezoidal plastic boxes 6. The stacking stability between the corrugated cardboard bodies 1 is greatly improved through this structure, and the collapse caused by sliding between the corrugated cardboard bodies 1 is effectively reduced, which is safer. In addition, when the corrugated cardboard bodies 1 need to be used as a group When loading the carton, after the head and tail cardboards are butted together according to the bending rule of the pressing groove 2, the connecting plate 4 is tightly attached to the inner side of the opening cardboard, and then the trapezoidal plastic box 6 is passed through the through hole 13. By rotating the flap 11 to a horizontal position, the anti-slipping member 12 can correspond to the positioning tube 14 one by one, so that the anti-slipping member 12 is pressed into the interior of the positioning tube 14 to complete the snap-fit ​​fixation, which is equivalent to the structure of a male buckle and a female buckle, and is not described here. Then, it can be quickly folded into a carton for use, which is simple and fast, and does not require the use of glue for bonding, so there is no need to wait for the bonding time. It is very convenient to use in some temporary venues, and it also avoids the limitation of no glue. At the same time, when carrying the packaged cartons, the hand hole 15 allows the user to better find the force point, improves the user experience, and plays a role in ventilation.
