Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a packaging structure. Background Technology

[0002] In the complete industrial chain of air conditioner manufacturing and sales, packaging, as a crucial transitional step from the production field to the distribution field, plays a vital role in ensuring the safety and integrity of air conditioners during transportation and storage. Appropriate packaging structures not only prevent air conditioners from being damaged by collisions, compression, moisture, etc., in the complex and ever-changing logistics environment, ensuring that the product reaches consumers in good condition, but also directly affect the company's production efficiency, cost control, and market competitiveness.

[0003] Currently, the packaging structures widely used for air conditioners in the market have revealed some problems that urgently need to be addressed during design and actual use. Among these, the excessive amount of packaging materials is a particularly prominent issue. Existing packaging solutions, in order to meet the comprehensive protection needs of air conditioners, often require the use of multiple different types of packaging materials. For example, thick foam plastic is used to cushion and protect the key components of the air conditioner, preventing damage from impacts during transportation; cardboard boxes serve as the main load-bearing containers, providing structural support for the air conditioner; in addition, various securing straps, moisture-proof bags, and other auxiliary packaging materials may also be involved.

[0004] The sheer variety of packaging materials presents an exceptionally complex packaging process. On the production line, workers must apply various packaging materials precisely to the air conditioner in a specific order and manner. Each packaging step requires strict operating procedures to ensure packaging quality and effectiveness. For example, when placing foam cushioning components, their position must be precise and tightly fitted to the contours of the air conditioner; otherwise, they will not provide the necessary cushioning. When sealing cardboard boxes, careful folding and pasting are necessary to ensure the boxes are airtight and secure. This complex packaging process not only demands high levels of worker skill, increasing training and labor costs, but also significantly extends the packaging time for a single air conditioner.

[0005] From a production efficiency perspective, the complexity of the packaging process has become a bottleneck restricting the entire air conditioner production flow. In today's increasingly competitive market, production efficiency directly affects a company's capacity and delivery speed. The cumbersome packaging process caused by existing packaging structures increases the operation time at each workstation on the production line, slows down the production cycle, and reduces the number of air conditioners that can be packaged per unit of time. This not only affects the company's production scale and economic benefits but may also lead to an inability to meet market demand in a timely manner and missed business opportunities.

[0006] Therefore, developing a new packaging structure for air conditioners that can effectively protect the air conditioners while reducing the use of packaging materials, simplifying the packaging process, and improving production efficiency has become a pressing technical problem for the air conditioner manufacturing industry. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a packaging structure.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] In one specific embodiment, the first packaging component includes a first inner box and a first outer box, the first inner box being connected to the inside of the first outer box, and the second packaging component includes a second inner box and a second outer box, the second inner box being connected to the inside of the second outer box; the first inner box is adapted to the second inner box, and the first outer box is adapted to the second outer box.

[0011] In one specific embodiment, the first inner box has a first cavity, the second inner box has a second cavity corresponding to the first cavity, and the first cavity and the second cavity are combined to form the storage cavity.

[0012] In one specific embodiment, both the first cavity and the second cavity are provided with limiting slots on their sides.

[0013] In one specific embodiment, the first inner box is provided with a limiting boss, and the second inner box is provided with a limiting groove corresponding to the limiting boss.

[0014] In one specific embodiment, the height of the limiting boss is greater than 5mm.

[0015] In one specific embodiment, the thickness of the first inner box and the second inner box is greater than 10 mm, and the thickness of the first outer box and the second outer box is greater than 20 mm.

[0016] In one specific embodiment, the first inner box protrudes from the first outer box, and the second inner box is recessed into the second outer box.

[0017] In one specific embodiment, both the first outer box and the second outer box have rope grooves on their outer periphery.

[0018] In one specific embodiment, both the first outer box and the second outer box are square in shape and have ridges formed around their edges, with adhesive tape attached to the ridges.

[0019] The advantages of this packaging structure compared to the prior art are as follows: the packaging structure is composed of a first packaging component and a second packaging component. During packaging, the air conditioner only needs to be placed in the second packaging component, and then the first packaging component is closed to complete the entire packaging process. This simplified operation reduces packaging steps, shortens the packaging time for a single air conditioner, and improves production efficiency. In addition, by designing the closing method of the first packaging component and the second packaging component to form a storage cavity for placing the air conditioner, the use of packaging materials is minimized while ensuring effective protection of the air conditioner.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0040] See Figures 1 to 9 As shown, this utility model discloses a specific embodiment of a packaging structure, including: a first packaging component 10 and a second packaging component 20, wherein the first packaging component 10 covers the second packaging component 20 and forms a storage cavity for placing items.

[0041] Specifically, the first packaging component 10 can be made of materials with a certain strength and toughness, such as high-strength corrugated cardboard or plastic sheets. Its shape is designed as a lid-like structure to fit the second packaging component 20. Taking a common household air conditioner as an example, if the air conditioner is rectangular in shape, the first packaging component 10 can be designed as a corresponding rectangular lid, with its size slightly larger than the projected size of the air conditioner in the corresponding direction, to ensure it can completely cover the second packaging component 20. Reinforcing structures, such as folded cardboard reinforcing ribs or raised ridges on the plastic sheets, can be added to the edges to enhance the structural strength of the lid and prevent deformation due to compression during transportation. The second packaging component 20 is also customized according to the shape and size of the air conditioner. It typically serves as the base supporting the air conditioner and can be made of the same material as the first packaging component 10 or a thicker material to ensure load-bearing capacity. For example, it can be made of double or multiple layers of corrugated cardboard or molded from a single piece of plastic with a certain degree of rigidity. The internal shape of the second packaging component 20 matches the bottom contour of the air conditioner and has corresponding grooves or protrusions for initial positioning and fixation of the air conditioner. For example, a special recessed area is provided at the location of heavier components such as the air conditioner compressor to make the air conditioner more stable.

[0042] At the contact edges of the first packaging component 10 and the second packaging component 20, mechanical connection structures can be provided to achieve a stable closing. For example, multiple buckles can be provided on the edge of the first packaging component 10, and corresponding slots can be provided at the corresponding positions on the second packaging component 20. When the first packaging component 10 is closed onto the second packaging component 20, the buckles can accurately engage in the slots, achieving a secure connection between the two. This connection method is simple to operate; simply align the first packaging component 10 with the second packaging component 20 and press down to allow the buckles to engage in the slots to complete the closing. Furthermore, to facilitate opening the packaging, the buckles and slots can be designed using materials with a certain degree of elasticity, so that when it is necessary to open the packaging, only a certain amount of external force is required to disengage the buckles from the slots.

[0043] Once the first packaging component 10 is placed on top of the second packaging component 20, the space between them forms a storage cavity for placing items. The size and shape of this cavity are precisely designed according to the item to be placed (such as an air conditioner), ensuring that the item can be placed securely without shifting during transport due to excessive space or being too small to fit. When placing the item, the air conditioner is first placed stably on the second packaging component 20, and its internal positioning structure is used to initially secure it. Then, the first packaging component 10 is slowly placed on top of the second packaging component 20, ensuring the clips accurately engage with the slots, completing the packaging process.

[0044] In other words, by constructing a packaging structure using the first packaging component 10 and the second packaging component 20, the air conditioner only needs to be placed in the second packaging component 20, and then the first packaging component 10 is closed to complete the entire packaging process. This simplified operation reduces packaging steps, shortens the packaging time for a single air conditioner, and improves production efficiency. Furthermore, by designing the closing mechanism of the first packaging component 10 and the second packaging component 20 to form a storage cavity for the air conditioner, the use of packaging materials is minimized while ensuring effective protection of the air conditioner. Additionally, the first packaging component 10 and the second packaging component 20 are tightly connected by a mechanical connection to form a stable storage cavity. This structure effectively prevents the goods from shifting or being damaged during transportation due to external pressure or collisions. For example, during long-distance transportation, even if encountering bumpy roads or collisions, the goods can maintain a relatively stable state within the storage cavity. Moreover, the materials used in the first packaging component 10 and the second packaging component 20, such as corrugated cardboard and plastic sheets, are mostly recyclable. After the packaging is used, these materials can be recycled and reused, reducing environmental pollution and conforming to the concept of sustainable development.

[0045] See Figures 1 to 9 As shown, in one embodiment, the first packaging component 10 includes a first inner box 11 and a first outer box 12, the first inner box 11 being connected to the inner side of the first outer box 12; the second packaging component 20 includes a second inner box 21 and a second outer box 22, the second inner box 21 being connected to the inner side of the second outer box 22; the first inner box 11 is adapted to the second inner box 21, and the first outer box 12 is adapted to the second outer box 22.

[0046] Specifically, the first outer box 12 can be made of high-strength, rigid materials, such as double-layer corrugated cardboard or high-density plastic sheets. Its shape is designed as a regular box structure, such as a cuboid, to meet common packaging needs. The edges and corners of the box can be reinforced, such as by increasing the number of folds in the cardboard or adding plastic corner protectors to enhance its resistance to compression and impact. Meanwhile, the surface of the first outer box 12 can be printed as needed, such as with company logos, product information, and shipping markings. The first inner box 11 is also customized according to the shape and size of the items to be placed. It is connected to the inside of the first outer box 12, and the connection method can be adhesive bonding, snap-fit ​​fixing, or integral molding. For example, if adhesive bonding is used, environmentally friendly adhesive is applied to the corresponding positions on the inside of the first outer box 12, and then the first inner box 11 is accurately placed and a certain pressure is applied to firmly bond it. The material of the first inner box 11 can be relatively soft and elastic, such as foam plastic or thickened pearl cotton, for cushioning and protecting the items. Its internal shape matches the corresponding part of the item, with corresponding grooves or protrusions to better secure the item.

[0047] The structure and materials of the second outer box 22 are similar to those of the first outer box 12 to ensure the stability and strength of the overall packaging structure. Its size and shape must be compatible with the first outer box 12 so that they fit tightly when closed. The second outer box 22 may also have features to facilitate handling, such as handle holes or grooves, for easy operation during transport and loading / unloading. The second inner box 21 is connected to the inside of the second outer box 22, and its connection method and material selection are similar to those of the first inner box 11. The second inner box 21 is mainly used to carry the items, working together with the first inner box 11 to provide comprehensive protection. Its internal structure is designed according to the bottom shape of the items, allowing it to fit tightly against the bottom of the items and prevent them from shifting inside the packaging.

[0048] In other words, the double-layer design of the first outer box 12 and the second outer box 22, as well as the first inner box 11 and the second inner box 21, provides multi-layered cushioning protection. When the packaging is subjected to external impact, the first outer box 12 and the second outer box 22 first absorb some of the energy, and then the first inner box 11 and the second inner box 21 further cushion the remaining impact force, effectively reducing the vibration and collision of the item and protecting it from damage. Furthermore, the fitting design of the first inner box 11 and the second inner box 21 allows the item to be precisely positioned and fixed within the packaging. The item is tightly wrapped between the two inner boxes, preventing it from moving around freely within the packaging and avoiding friction and collision caused by movement, further improving the protective effect of the item. Additionally, the fitting design of the first outer box 12 and the second outer box 22 ensures a tight fit of the packaging structure. When the two are closed, they form a whole, enhancing the strength and stability of the packaging and better resisting external pressure and compression. For example, during stacking storage or transportation, the tightly fitting outer box structure can evenly distribute pressure, preventing packaging deformation or damage.

[0049] See Figures 2 to 9 As shown, in one embodiment, the first inner box 11 is provided with a first cavity 111, and the second inner box 21 is provided with a second cavity 211 corresponding to the first cavity 111, and the first cavity 111 and the second cavity 211 are combined to form the storage cavity.

[0050] Specifically, the first cavity 111 is designed based on the shape of the upper part of the item to be placed. For example, if the packaged item is an electronic product with a curved top and specific protruding structures, the first cavity 111 needs to precisely fit these features. The design of the second cavity 211 matches the shape of the lower part of the item.

[0051] In other words, the first cavity 111 and the second cavity 211 are designed according to the upper and lower shapes of the item, respectively. The combined cavity provides a tight fit, offering comprehensive and precise protection. The item will not shake or collide within the cavity, effectively preventing damage caused by vibration and compression during transportation. For example, for precision electronic devices, this snug fit protects sensitive internal components from external impacts. Furthermore, the materials of the first inner box 11 and the second inner box 21 typically have a certain degree of elasticity, such as foam or sponge, which cushion and absorb shocks when the item is subjected to external impact. When the packaging is bumped or squeezed, the cavity material absorbs and disperses some energy, reducing the impact force transmitted to the item and further protecting its safety. Additionally, since the first cavity 111 and the second cavity 211 correspond to the upper and lower parts of the item, when the item needs to be removed, simply open the first packaging assembly 10 to detach the upper part of the item from the first cavity 111, and then remove the item from the second cavity 211. The operation is convenient and quick. Similarly, items are placed in the reverse order, which improves the efficiency of taking and putting in items.

[0052] See Figure 2 , Figure 5 , Figure 6 and Figure 9 As shown, in one embodiment, both the first cavity 111 and the second cavity 211 are provided with limiting slots 112 on their sides.

[0053] Specifically, the shape and size of the limiting slot 112 are designed according to the shape characteristics of the side of the item. For example, if the side of the item has a protruding cylindrical part, the limiting slot 112 is designed as a matching semi-circular groove; if the side of the item has an irregular protrusion structure, the limiting slot 112 is customized according to the contour of the protrusion structure. The item is placed in the second cavity 211, so that the corresponding part of the side of the item is embedded in the limiting slot 112 on the side of the second cavity 211. Then, the first packaging component 10 is placed on top of the second packaging component 20, so that the side of the upper part of the item is embedded in the limiting slot 112 on the side of the first cavity 111. At this time, the item is firmly fixed in the storage cavity by the limiting slot 112 and cannot move around freely.

[0054] In other words, the limiting slot 112 restricts the item from multiple directions, effectively preventing the item from swaying horizontally, vertically, or tilting during transportation and storage. For example, during vehicle transportation, due to road bumps, the packaging will be subjected to impact forces from various directions. The limiting slot 112 can firmly hold the item in place, preventing the item from colliding with the inner wall of the packaging, thereby protecting the item from damage.

[0055] See Figures 2 to 9As shown, in one embodiment, the first inner box 11 is provided with a limiting protrusion 113, and the second inner box 21 is provided with a limiting groove 212 corresponding to the limiting protrusion 113.

[0056] Specifically, the shape of the limiting boss 113 can be square or circular. The shape of the limiting groove 212 corresponds to that of the limiting boss 113. If the limiting boss 113 is square, then the limiting groove 212 is a square groove; if the limiting boss 113 is circular, then the limiting groove 212 is a circular groove. Its size should be slightly larger than that of the limiting boss 113 to leave a certain assembly gap, generally between 0.1 and 0.3 mm, to facilitate the smooth insertion of the limiting boss 113 into the limiting groove 212.

[0057] In other words, the limiting protrusion 113 and the limiting groove 212 effectively restrict the relative movement of the first inner box 11 and the second inner box 21 during transportation. When the packaging is subjected to external impact or vibration, the limiting protrusion 113 is engaged in the limiting groove 212, preventing the first inner box 11 and the second inner box 21 from misaligning or separating, thereby maintaining the overall structural stability of the packaging and preventing damage to the goods due to loose packaging structure. This limiting structure increases the impact resistance of the packaging. During transportation, bumps and collisions caused by vehicle movement will generate significant impact forces. The cooperation between the limiting protrusion 113 and the limiting groove 212 can distribute the impact force across the entire packaging structure, reducing excessive local stress and improving the packaging's protective performance for the goods.

[0058] In one embodiment, the height of the limiting boss 113 is greater than 5 mm.

[0059] Specifically, the height of the limiting boss 113 is greater than 5 mm. After the first inner box 11 and the second inner box 21 are closed, the contact area between the limiting boss 113 and the limiting groove 212 is larger, thus providing greater limiting resistance. When the packaging structure is subjected to external forces, it can more effectively prevent the relative movement of the first inner box 11 and the second inner box 21, reduce the shaking amplitude of the items within the packaging structure, and improve the stability of the packaging. In addition, during transportation, the items may encounter significant impact forces, such as sudden braking or collisions. The higher limiting boss 113 can withstand greater impact forces without deformation or damage, ensuring that the limiting function is always effective and protecting the items from damage.

[0060] In one embodiment, the thickness of the first inner box 11 and the second inner box 21 is greater than 10 mm, and the thickness of the first outer box 12 and the second outer box 22 is greater than 20 mm.

[0061] Specifically, thicker inner and outer boxes provide greater cushioning. When the packaging is subjected to external impacts, such as falling objects or collisions, the materials of the inner and outer boxes deform, absorbing and dispersing the impact energy and reducing the impact force transmitted to the items. For example, in logistics transportation, goods may be impacted by other goods; inner boxes thicker than 10mm and outer boxes thicker than 20mm can effectively protect the contents from damage. Additionally, during transportation, vehicle movement generates vibrations, and thicker packaging can act as a vibration damper. The materials of the inner and outer boxes can absorb and attenuate vibration energy, reducing the amplitude of shaking of items within the packaging and protecting the delicate components of the items from vibration. This cushioning protection is particularly important for vibration-sensitive items such as electronic products and optical instruments. Furthermore, thicker outer boxes have higher compressive strength and can withstand the pressure of stacking. During warehouse storage or transportation, multiple packages are stacked together; thicker outer boxes can prevent the packaging from being crushed, protecting the contents from compression. For example, in large warehouses, goods may be stacked several meters high. Outer boxes thicker than 20mm ensure the safety of the bottom packaging and the goods themselves. Furthermore, thicker packaging materials are more wear-resistant and durable, able to withstand friction, collisions, and other external forces during transportation. Compared to thinner packaging, inner boxes thicker than 10mm and outer boxes thicker than 20mm are less prone to damage or tearing, thus extending the packaging's lifespan. For packaging that needs to be used multiple times, such as reusable logistics packaging, this feature can reduce packaging costs.

[0062] See Figures 2 to 9 As shown, in one embodiment, the first inner box 11 protrudes from the first outer box 12, and the second inner box 21 is recessed into the second outer box 22.

[0063] Specifically, the size of the first inner box 11 protruding from the first outer box 12 is determined based on the packaging dimensions, the size of the items, and the required limiting effect. Generally, the protrusion size can be between 5-15 mm. For example, if the items inside the packaging are large and require more precise limiting, the protrusion size can be designed to be 10-15 mm; if the items are small, the protrusion size can be designed to be 5-10 mm. The size of the second inner box 21 recessed within the second outer box 22 should match the size of the first inner box 11 protruding from the first outer box 12 to ensure that after the first packaging component 10 closes the second packaging component 20, the second outer box 22 can accurately limit the first inner box 11. The recessed size can also be between 5-15 mm, with the specific value adjusted according to the protrusion size of the first inner box 11.

[0064] In other words, the second outer box 22 not only restricts the horizontal movement of the first packaging component 10 but also limits its vertical swaying to a certain extent. When the packaging structure is subjected to external force, the protruding part of the first inner box 11 and the concave part of the second outer box 22 cooperate to form a stable limiting structure, effectively reducing the shaking and displacement of the packaging structure during transportation and storage, and improving the stability of the packaging structure. In addition, by precisely designing the size and shape of the protrusion of the first inner box 11 and the concave part of the second outer box 22, high-precision limiting can be achieved. This precise limiting can ensure that the items inside the packaging structure will not collide or be damaged due to the shaking of the packaging structure during transportation, especially for some precision electronic equipment, optical instruments, and other items with high positional accuracy requirements, providing better protection.

[0065] See Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, both the first outer box 12 and the second outer box 22 are provided with rope grooves 121 on their outer periphery.

[0066] Specifically, the location of the binding groove 121 is determined based on the shape and size of the first outer box 12 and the second outer box 22, as well as the requirements for the binding rope. Typically, the binding groove 121 can be located on the four sides of the outer box, especially the two opposite long sides, facilitating binding operations from different directions. For example, for a cuboid-shaped outer box, a binding groove 121 is placed in the middle of the long side, ensuring the stability of the binding rope without affecting the normal opening and closing of the outer box. The size of the binding groove 121 is determined based on the diameter and number of binding ropes. The width of the groove should be slightly larger than the diameter of the binding rope, generally 1-2 mm larger, to ensure that the binding rope can be easily placed into the groove without easily slipping out. The depth of the groove can be designed according to actual needs, typically between 3-8 mm. Too shallow a depth may result in the binding rope not being securely fixed, while too deep a depth may affect the structural strength of the outer box. Suitable binding ropes should be selected; their material can be nylon, polyester fiber, etc., which have high strength and abrasion resistance. The diameter of the binding rope should be selected according to the size of the binding rope groove 121 to ensure it can be smoothly inserted into the groove. Place one end of the binding rope into the binding rope groove 121 of the first outer box 12 or the second outer box 22, and then use glue or tape to attach and fix the binding rope in the groove. Glue can be instant adhesive, epoxy resin glue, etc., which have the characteristics of fast curing and strong adhesion; tape can be double-sided tape or cloth tape, which is easy to use.

[0067] In other words, the binding groove 121 provides a fixed position for the binding rope, eliminating the need for operators to spend time searching for suitable binding points. Operators simply place the binding rope into the groove to perform the binding operation, significantly improving the binding efficiency of the packaging structure. Especially in batch packaging operations, it can significantly shorten packaging time and increase production efficiency. Furthermore, the binding groove 121 restricts the movement of the binding rope, preventing slippage or loosening during use. The binding rope, constrained by the sidewalls of the groove, can wrap more tightly around the outer box, enhancing the binding stability of the packaging structure and effectively preventing the packaging structure from unraveling during transportation.

[0068] In one embodiment, both the first outer box 12 and the second outer box 22 are square in shape and have ridges around their edges, with adhesive tape attached to the ridges.

[0069] Specifically, the presence of the corrugations increases the thickness and structural strength of the outer box, enabling it to withstand greater external pressure. During stacking storage or transportation, multiple packaging structures are piled together, with the lower outer box bearing the weight of the upper packaging structure. The combined action of the corrugations and adhesive tape effectively disperses pressure, preventing the outer box from being crushed and protecting the internal contents from damage. When the outer box is subjected to collisions or impacts, the corrugations and adhesive tape act as buffers and disperses the impact force. The elastic deformation of the corrugations absorbs some of the impact energy, while the adhesive tape secures the corrugations, preventing excessive deformation or breakage under impact, thereby reducing the impact on the internal contents. Furthermore, during the transportation and handling of the packaging structure, the corrugations of the outer box are prone to friction and collision with surrounding objects, leading to wear or damage. The adhesive tape applied to the corrugations forms a protective layer, reducing direct contact between the corrugations and external objects, lowering the risk of corrugation wear, and extending the lifespan of the outer box. Additionally, the connection between the corrugations and adhesive tape enhances the overall structural stability of the outer box, preventing deformation during use. Even if the outer box is subjected to a certain external force, the corners and adhesive tape can maintain the shape of the outer box, ensuring that the packaging structure can perform its function of protecting the goods normally.

[0070] In one embodiment, the first inner box 11 and the second inner box 21 are integrally molded from pulp, and the first outer box 12 and the second outer box 22 are composite molded from honeycomb paperboard.

[0071] Specifically, both the molded pulp inner box and the honeycomb cardboard outer box are made of paper, a recyclable resource. After use, these packaging materials can be recycled and reprocessed into new paper products, reducing the consumption of natural resources and minimizing environmental pollution. Furthermore, paper materials gradually degrade in the natural environment, unlike some plastic packaging materials which persist in the environment for extended periods, causing "white pollution." The use of all-paper packaging aligns with the concept of sustainable development and is beneficial for protecting the ecological environment. In addition, the molded pulp inner box has excellent cushioning properties; its internal fiber structure absorbs and disperses external impacts, effectively protecting the contents from damage. The honeycomb cardboard outer box has high strength and rigidity, capable of withstanding certain pressure and impacts, providing reliable protection for the inner box and its contents. The honeycomb cardboard molded composite outer box has a stable structure; its honeycomb core layer evenly distributes stress, improving the outer box's resistance to compression and bending. Simultaneously, the molding process allows for precise control of the outer box's shape and dimensions, ensuring packaging consistency and stability. Furthermore, using waste paper and cardboard scraps as raw materials for pulp-molded inner boxes, and kraft paper as raw material for honeycomb cardboard outer boxes, offers a wide range of readily available and relatively inexpensive raw material sources, effectively reducing packaging production costs. Pulp molding and honeycomb cardboard molding processes are relatively simple, with lower equipment investment and operating costs. Simultaneously, these processes can be automated, improving production efficiency and further reducing production costs.

[0072] In one embodiment, a protective film is applied to the first outer box 12 and the second outer box 22, or text content such as product information and production information is printed on the surface of the first outer box 12 and the second outer box 22.

[0073] Specifically, protective film forms a barrier on the surface of the outer box, effectively preventing dust and debris from adhering to it, keeping the box clean and aesthetically pleasing. This is especially important for products with high requirements for packaging appearance, enhancing the overall product image. In addition, protective film has a certain degree of abrasion and scratch resistance, reducing scratches and wear on the outer box during transportation, storage, and use, extending its lifespan. Particularly in packaging that requires frequent handling and stacking, protective film provides excellent protection. Some protective films also have good moisture-proof and stain-proof properties, preventing moisture and stains from penetrating into the inner box and protecting the contents from damage. This is highly advantageous for product packaging that requires high humidity and cleanliness.

[0074] By printing product and production information on the outer box, consumers can easily access important information such as the product's name, specifications, model, production date, and shelf life, facilitating product selection and use. Simultaneously, production information helps companies trace and manage product quality. Furthermore, the printed text can incorporate the company's brand logo and slogans, serving as a form of brand promotion. Exquisite printing design can enhance brand awareness and reputation, strengthening consumer recognition and trust. Additionally, special printing processes or inks, such as anti-counterfeiting inks and microtext printing, can be used to print anti-counterfeiting information on the outer box surface, preventing counterfeit and substandard products and protecting the legitimate rights and interests of both businesses and consumers.

[0075] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
