Technical Field
[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a self-locking corrugated 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 their usage has always been the first among various 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, and have become the main force of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products, which are beneficial to environmental protection and loading and unloading transportation. The self-locking structure at the bottom of traditional corrugated boxes is easily affected by the weight of the goods, causing the problem of expansion, and the box cover is mostly directly installed, which is also prone to the problem of accidental opening. For this reason, we propose a self-locking corrugated box. Utility Model Content
