Technical Field
[0001] This utility model relates to the field of cardboard box technology, and in particular to an integrated environmentally friendly cardboard box. Background Technology
[0002] Cardboard boxes are the most widely used packaging products in modern society. They can be used to package small items such as clothes and food, as well as large items such as televisions and refrigerators. They have a wide range of applications and are popular due to their low price and good performance. Most cardboard box forming methods use slots cut into the cardboard to splice the cardboard pieces together, or to nail multiple cardboard pieces together. This method results in an unstable structure of the formed cardboard box, and the forming process is relatively complex, requiring multiple machines to work together, which is inefficient.
[0003] Currently, to improve customer experience and facilitate product carrying, a large number of cardboard boxes require carrying handles. Conventional cardboard boxes typically incorporate carrying handles in several ways: 1) Adding a separate plastic carrying handle, which increases cost and is environmentally unfriendly; 2) Using a gift box-style structure with a separately designed carrying handle, which increases paper usage, costs, and space requirements, impacting stacking and transport space; 3) Using a cut-out handle hole in the cardboard box, which requires internal clearance for the handle area, resulting in a poor user experience. Therefore, we propose a new integrated environmentally friendly cardboard box. Utility Model Content

When forming the cardboard box, firstly, fold the first side panel 11, the second side panel 12, the third side panel 13, the fourth side panel 14 and the overlapping surface 2 sequentially along the longitudinal fold line 5. The overlapping surface 2 is parallel and coincident with the first side panel 11. Then, fix the first side panel 11 and the overlapping surface 2 together with tools such as tape or sealing nails. At this time, the first side panel 11, the second side panel 12, the third side panel 13 and the fourth side panel 14 are perpendicular to each other. Next, fold the first bottom panel 31, the first bottom panel 32, the third bottom panel 33 and the fourth bottom panel 34 to form the bottom of the cardboard box. Then, fold the second top cover perpendicular to the second side panel 12 along the first fold line 7. Then, pull up the handle piece along the fifth fold line 83. Then, fold the two handle plates 92 in half along the sixth fold line 93. At this time, the handle plates 92 are perpendicular to the second cover plate 8. In state 1, due to the seventh fold line 94 between the folding plate 91 and the handle plate 92, the folding plate 91 can be inserted into the bottom of the second cover plate 81 and kept parallel to the second cover plate 81. Then, the two flaps 4 are folded along the horizontal positive fold line 6 so that the two flaps 4 are kept parallel to the second cover plate 81. Then, the first insert plate 8 is folded away from the carton along the second fold line 9. Then, the second insert plate 73 is folded perpendicular to the first cover plate 71 along the fourth fold line 75. Then, the first top cover is folded perpendicular to the fourth side plate 14 along the first fold line 7. At this time, the folded handle will pass through the handle groove 72, and the second insert plate 73 will be inserted into the second slot 82 opened on the second cover plate 81. Finally, the first insert plate 8 is folded vertically using the third fold line 10 on the first insert plate 8, and then one end of the first insert plate 8 is inserted into the first slot 74. This invention explains that when stacking cardboard boxes, the fifth fold line 83 can be used to fold the folded handle plate 92 into the handle groove 72, allowing for stacking. Compared to existing integrated environmentally friendly cardboard boxes, this invention features a built-in handle, making it convenient for customers to pick up items and providing a comfortable experience. It utilizes existing cardboard materials, without increasing paper costs, occupying extra space, affecting stacking, or impacting transportation space.
