[0015] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] Example 1.

[0017] like Figure 1 and Figure 2 As shown, the cardboard packaging structure described in this embodiment includes a plate-like base layer 1 and a contact layer 2 with a wavy structure, the troughs of the wavy structure form a storage space 3, and a first straight section 4 is formed along the wave bottom of the wavy structure, and the contact layer 2 is fixedly connected to the base layer 1 through the first straight section 4.

[0018] In specific implementation, the base layer 1 and the contact layer 2 are made of recycled paper, and the base layer 1 and the contact layer 2 have certain strength and toughness, ensuring that the base layer 1 has sufficient strength to support the entire packaging structure. At the same time, the contact layer 2 is manufactured to have a wavy structure, and the trough of the wavy structure (storage space 3) is specially designed to accommodate long straight products to ensure that the products are stably placed inside the package.

[0019] Specifically, the wave bottom of the wavy structure (contact layer 2) extends to form a first straight section 4, which serves as a connection point between the contact layer 2 and the base layer 1. The two are connected and fixed by an adhesive or other appropriate fixing method to ensure that the two layers (1, 2) have sufficient contact area to form a stable packaging structure, thereby improving the overall load-bearing capacity of the packaging structure.

[0020] When in use, first place the long straight products in turn into the storage space 3 formed by the wavy contact layer 2 to ensure that each product is properly supported and protected. After the products are placed, the packaging structure is finally packaged, such as using tape, strapping tape or other packaging boxes to seal the package to ensure the safety of the products during transportation.

[0021] In this way, the design of the aforementioned storage space 3 provides good support and cushioning protection, reduces friction and impact during transportation, reduces the risk of product damage, and is very suitable for the compact arrangement of long straight-shaped products such as pens, thereby improving packaging efficiency and space utilization. At the same time, the use of recycled paper and simplified connection methods helps to reduce the production cost of the packaging structure, responds to the concept of environmental protection, and meets the current market demand for sustainable products. In addition, the structural design of the plate-like base layer 1 and the wavy contact layer 2 is convenient for handling and display, and is suitable for the needs of retail environments and logistics transportation.

[0022] As some optional implementations, Figure 1 and Figure 2 As shown, in order to improve the overall stability of the packaging structure, a second straight section 5 is provided in each crest of the contact layer 2, and the second straight section 5 is located between the crest of the corresponding crest and the bottom of the adjacent crest, and the plane where the second straight section 5 is located is perpendicular to the plane where the first straight section 4 is located.

[0023] In this embodiment, if Figure 2 As shown, the adjacent second straight section 5 is combined with the first straight section 4 to form a unique "ㄩ"-shaped structure. When multiple packaging structures are stacked, this "ㄩ"-shaped structure can effectively improve the compressive strength of the packaging structure without excessive deformation or collapse, thereby protecting the internal products from damage.

[0024] As some optional implementations, Figure 1 and Figure 2 As shown, the first straight section 4 and the second straight section 5 are connected by a rounded transition.

[0025] In this embodiment, the structural design of the rounded corner transition, on the one hand, can reduce stress concentration points compared to the arc-shaped transition, and can effectively disperse local stress, especially when subjected to greater pressure, to improve the overall strength of the packaging structure; on the other hand, for the scenario where the packaging structure needs to curl and fold, the rounded corner transition can reduce the resistance during the folding process, making the folding smoother and reducing the risk of material damage at the fold.

[0026] As some optional implementations, Figure 1 and Figure 2As shown, for the convenience of stacking and storage, the crests of all crests of the contact layer 2 are located on the same horizontal plane. With this structural design, the crests form a plane, which can more evenly disperse the pressure from above, reducing the risk of a single crest being subjected to excessive pressure during stacking, storage or transportation.

[0027] The cardboard packaging structure provided in this embodiment, through its unique wavy structural layer design, not only gives the packaging excellent cushioning performance and reinforced structural strength, but also improves packaging efficiency through sophisticated space utilization. In addition, the structure is made of environmentally friendly recycled paper materials, which not only effectively replaces traditional plastic packaging materials and reduces the burden on the environment, but also complies with the concept of sustainable development, bringing a new solution that is both environmentally friendly and efficient to the modern packaging industry.

[0028] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
