Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to an extra-large high-strength corrugated paper box. Background Art

[0002] Corrugated cardboard is die-cut, creased, and stapled or glued together to create corrugated boxes. Corrugated boxes are the most widely used packaging product, consistently leading the way in terms of volume consumption. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes, with their superior performance and processability, have gradually replaced wooden boxes and other transport containers, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating storage and transportation, they also enhance product aesthetics and promote their value. Corrugated boxes are environmentally friendly and facilitate both loading and unloading. When packaging and transporting some large appliances, 0203 boxes (large-lid boxes) are required, which also imposes certain structural requirements. The compressive strength of a corrugated box is measured by the maximum load and deformation required to break the box under uniform dynamic pressure applied by a compression testing machine.

[0003] After searching the existing public patent number: CN202020736558.7, the public patent name is: A high-strength corrugated box, belonging to the field of carton manufacturing, a high-strength corrugated box, including an outer shell, a pair of box covers are provided at the upper end of the outer shell, and the inner side wall of the outer shell is opened with a pair of placement grooves, and the inner walls of the pair of placement grooves are fixedly connected with a fixing plate, and the upper ends of the pair of fixing plates are fixedly connected with a rotating shaft, and the pair of rotating shafts are rotatably connected to the fixing plate through the rotating shaft. The upper ends of the pair of box covers are opened with a slide groove, the pair of slide grooves are on the same horizontal axis, and the inside of the slide grooves are slidably connected with a slide rod, and the pair of slide rods are arranged in opposite directions, and the upper ends of the slide rods are fixedly connected with a handle, and the ends of the pair of box covers close to each other are fixedly connected to the support rod, and the upper ends of the pair of support rods are opened with a pair of through holes, which can realize the corrugated box to carry heavier items when in use, reduce the wear of the corrugated box during transportation, and effectively ensure that the items inside the box are not damaged.

[0004] However, the above-mentioned carton lacks reinforcement for the corners, has a light and insufficient structure, and the internal space cannot be adjusted during use. This will result in a large amount of filler being required to wrap the items if the items placed are small, so there is room for improvement. Utility Model Content
