Description

Technical Field

[0001] This utility model belongs to the field of packaging, and in particular relates to the structural design of packaging boxes for heavy-duty lawn mowers. Background Technology

[0002] As people's living standards improve, more and more families own private gardens or lawns. Lawns often grow faster due to seasonal and climatic factors. To maintain the beauty and integrity of the lawn, lawnmowers can help homeowners easily maintain it and keep it looking good. During the peak growing season, such as spring and autumn, cool-season lawns may need to be mowed weekly. Warm-season lawns, however, require more frequent mowing during the summer's peak growing season, possibly every five days. The lawnmower was originally invented to solve the inefficiency and labor-intensive problems of traditional mowing methods, while also meeting people's needs for lawn maintenance. Before the invention of lawnmowers, people mainly relied on hand-held long-handled sickles to mow grass, a method that was not only inefficient but also very labor-intensive. Especially on large lawns or pastures, manual mowing required a lot of labor and time, and it was difficult to ensure the evenness and smoothness of the mowing. When transporting lawnmowers to customers' homes, the stability, safety, and integrity of the packaging are crucial considerations. Paper-plastic packaging, with its significant advantages, has become the preferred choice. Paper-plastic assembly is far simpler than traditional environmentally friendly corrugated cardboard, eliminating complex folding and forming steps and saving manpower. It also provides ample protection, an attractive appearance, and excellent shock absorption, fulfilling all the performance requirements for transport packaging. The pulp pallet industry is poised to develop towards environmental friendliness, intelligence, functionality, and high performance in the future, while its application scenarios will continue to expand, resulting in a broad market prospect.

[0003] Currently, lawnmower exports are typically shipped in the form of complete machines, parts, and accessory packages, with packaging types including cartons, pallets, and wooden crates. Common packaging techniques often suffer from over-packaging and large volume. Therefore, rationally planning loading schemes to improve container loading efficiency is crucial. How to compress cushioning space while ensuring safety is a key consideration. Furthermore, packaging design should be tailored to different transportation environments, durations, and machine sizes, adjusting cushioning materials to meet transportation needs. Labor costs are currently a major component of total costs for businesses, typically accounting for 17%-25%. Excessive labor costs can weaken a company's competitiveness in the international market; therefore, minimizing packaging steps and minimizing worker assembly and handling are important design considerations. The "2024-2025 Energy Conservation and Carbon Reduction Action Plan" aims to reduce energy consumption per unit of GDP and lower carbon dioxide emissions, strengthen carbon emission intensity management, and implement energy conservation and carbon reduction actions across various sectors and industries. The paper industry, as a major carbon emitter, is taking a series of measures. With the advancement of global plastic bans and restrictions, the paper and plastics industry has received strong policy support. Utility Model Content

[0019] like Figure 1As shown, the present invention provides a packaging box for a heavy-duty lawnmower, including an outer box 100 and an inner liner assembly 200 placed inside the outer box 100. The inner liner assembly 200 includes an upper liner 10 and a lower liner 20. The upper liner 10 includes two interlocking layers of paper-plastic material, an upper paper tray 11 and an upper composite paper tray 12. When the upper paper tray 11 and the upper composite paper tray 12 are interlocked, an upper storage cavity 30 is left between them. The lower liner 20 includes two interlocking layers of paper-plastic material, a lower paper tray 21 and a lower composite paper tray 22. When the lower paper tray 21 and the lower composite paper tray 22 are interlocked, a lower storage cavity 40 is left between them. The present invention adopts a double-layer snap-fit ​​structure for the inner lining cushioning part to increase the strength of the inner lining. With the increase in the strength of the inner lining, the packaging volume can be reduced as much as possible, solving the problem of excessively large packaging in the prior art, and reducing warehousing and transportation costs as much as possible. The upper storage cavity 30 is used to store small accessories or tools F of the product W, while the lower storage cavity 40 can place detachable components G of the product, such as chains.

[0020] Depend on Figure 2 and Figure 3 As shown, although this utility model adopts a double-layer structure to increase cushioning resistance, its specific structural design still requires more ingenious design for support. The upper paper tray 11 of this utility model has a first protrusion 111 and a first groove 112. The upper composite paper tray 12 has a second groove 121 corresponding to the first protrusion 111 and a second protrusion 122 corresponding to the first groove 112. The lower paper tray 21 has a third protrusion 211 and a third groove 212. The lower composite paper tray 22 has a fourth groove 221 corresponding to the third protrusion 211 and a second protrusion 222 corresponding to the third groove 212. The upper pad 10 and lower pad 20 of this utility model are designed with various convex and concave structures to support impacts in all directions and improve cushioning capacity. Due to the double-layer design and the fit of various convex and concave structures, the cushioning and impact resistance can be maximized. All the protrusions are designed according to the product shape, which can not only play a cushioning role, but also play a product positioning role.

[0021] Depend on Figure 2 and Figure 3As shown, the lower composite paper tray 22 of this invention has a fifth groove 223 on its side, and a mesh-like first reinforcing rib 224 is molded at the bottom of the fifth groove 223. The lower paper tray 21 has a fifth protrusion 213 corresponding to the fifth groove 223, and a mesh-like second reinforcing rib 214 is molded at the bottom of the fifth protrusion 213. The upper composite paper tray 12 has a sixth groove 123 on its side corresponding to the fifth groove 223, and a mesh-like third reinforcing rib 124 is molded at the bottom of the sixth groove 123. The upper paper tray 11 has a sixth protrusion 113 corresponding to the sixth groove 123, and a mesh-like fourth reinforcing rib 114 is molded at the bottom of the sixth protrusion 113. This invention incorporates a partial support structure between the various convex and concave structures. During the paper-plastic palletizing process, slurry may accumulate at the bottom of the fifth groove 223 and the sixth groove 123. By utilizing this process, a support structure can be installed at these locations, not only saving on post-processing steps but also providing stronger support for the pallet structure and improving the overall impact resistance of the packaging. The positioning structure designed on the sides of the upper and lower paddings allows for a reduction in packaging size by utilizing the product's support structure. Positioning the external support structure (such as a support rod) at the fifth groove 223 and the sixth groove 123 utilizes the product's own protective structure to ensure product safety, reducing the need for additional side cushioning components in the packaging and thus reducing the overall packaging size.

[0022] Depend on Figure 2 and Figure 3 As can be seen from the diagram, the third protrusion 211 in this invention includes strip-shaped protrusions running longitudinally and transversely on the lower paper tray 21, with a seventh groove 215 molded through the middle of the strip-shaped protrusions. The first protrusion 111 includes strip-shaped protrusions running longitudinally and transversely on the upper paper tray 11, with an eighth groove 115 molded through the middle of the strip-shaped protrusions. The structural design of the strip ribs being discontinuous in this invention is mainly to adapt to the packaging requirements of some horizontal bars or connecting rods in the packaged products, and more importantly, to improve the impact resistance of the ribs. The discontinuous structural design improves the buffering capacity of the ribs, and the supporting structures in various directions also significantly improve the impact resistance of the ribs.

[0023] Depend on Figure 4As can be seen from the diagram, the packaging box of this utility model also includes an inner liner 30, which is made of cardboard folded into a cylindrical support structure. The cylindrical support structure folded on the inner liner 30 includes a transverse support 31 and a longitudinal support 32. The packaging box of this utility model is designed with an internal support structure, mainly to prevent impacts on the internal components of the product during transportation or loading and unloading, thus affecting the product's performance. Therefore, this utility model designs an internal support structure to support the internal components of the product and ensure its safety.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
