[0030] As another embodiment of the present invention, it also includes a side plate 13, which is disposed between the outer paper card 1 and the cover plate 3.
[0031] In another embodiment of this utility model, the cover plate 3, the side plate 13 and the outer paper card 1 are integrally formed.
[0032] This invention provides a fully paper-based packaging for flexible metal sheets, primarily using corrugated cardboard as the base material. Through ingenious structural design, the product is suspended and secured, effectively protecting the flexible thin metal sheet from impact and compression during transportation and storage. This packaging features simple forming, low paper consumption, no nails or adhesives, and is environmentally friendly and recyclable. It meets ISTA 2A testing requirements, satisfying the protection needs of high-intensity transportation environments.
[0033] The packaging and assembly process is as follows:
[0034] First, as shown in Figure 3, the supporting paper tube 5 is folded along the pre-reserved crease line on the inner paper card 2, and the iron sheet 12 is placed on the supporting paper tube 5. The flexible thin iron sheet 12 is suspended and fixed inside the packaging to avoid direct contact between the product and the inner wall of the packaging box, thereby reducing impact and vibration during transportation. The first paper tube 6 is folded along the crease line and abuts against one side of the supporting paper tube 5. The height of the first paper tube 6 is higher than that of the supporting paper tube 5. The first paper clip 7 consists of several pieces of paper cut from the first paper tube 6 and remains connected to the first paper tube 6, as shown in Figures 1 and 4. The iron sheet 12 is located between the supporting paper tube 5 and the first paper clip 7, achieving reliable fixation of the product in a clever and low-cost manner. The first paper tube 6 also provides fixed support for the side of the iron sheet 12.
[0035] Next, as shown in Figure 2, the second paper tube 8 is folded along the pre-reserved crease line on the outer paper card 1. The folded inner paper card 2 is placed on the outer paper card 1, and the second paper buckle 9 is pressed against the top of the iron sheet 12. At the same time, the second paper tube 8 supports and fixes the end of the iron sheet 12. The buckle and paper square tube formed by folding corrugated cardboard are tightly attached to both sides of the inner wall of the packaging box and perfectly integrated with the box body. When subjected to impact, it first bears and disperses most of the pressure, effectively playing a protective role.
[0036] Finally, the cover plate 3 and side plate 13 are folded towards the outer paper card 1, and the tongue 11 of the cover plate 3 is inserted into the insertion hole 10 of the second paper tube 8 to seal the packaging. The folded side plate 13 forms the side of the entire packaging, thus completing the packaging assembly, as shown in Figure 7. The use of corrugated cardboard folds to form snaps eliminates the need for glue, tape, and other adhesive substances, meeting environmental protection requirements. The packaging is reliable in strength and easy to operate, requiring no tools for easy disassembly, thus achieving environmentally friendly all-paper packaging.
[0037] By utilizing the snap-fit mechanism formed by folding corrugated cardboard and paper square tubes, a flexible thin iron sheet 12 is suspended and fixed inside the packaging, preventing direct contact between the product and the inner wall of the box, thus reducing impact and vibration during transportation. The packaging design is simple, adhesive-free, easy to operate, and environmentally friendly, aligning with current green and environmentally friendly development trends. It also reduces packaging costs and increases aesthetics. Users can easily disassemble the packaging by hand without the need for scissors or other tools, enhancing the user experience.
[0038] This invention uses all-paper material (corrugated cardboard), which is fully biodegradable and recyclable, avoiding the environmental pollution caused by traditional plastic packaging (such as EPS and EPE), and aligning with the trend of green packaging development. Through snap-fit and paper square tube structures, a flexible thin iron sheet is suspended and fixed inside the packaging, preventing direct contact between the product and the inner wall of the box, effectively reducing impact and vibration during transportation. The internal design of the packaging features a cushioning support structure formed by multiple layers of folded corrugated cardboard, significantly improving compression and impact resistance, ensuring product safety under high-intensity transportation environments. The packaging design of this invention meets ISTA 2A testing requirements and is suitable for harsh transportation environments. Optimized structural design reduces paper usage, lowering packaging weight and production costs. Avoiding the use of auxiliary materials such as metal staples and adhesives further reduces material costs and production complexity. Modular design and simplified production processes improve production efficiency, making it suitable for large-scale application.
[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
