[0002] Packaging boxes play a crucial role in the modern product packaging industry. They are containers formed by cutting and folding raw materials to create specific shapes, tailored to the packaging and storage needs of different items. From a protective perspective, they effectively resist collisions, compression, and environmental damage during transportation, ensuring the product remains intact. Aesthetically, unique designs, exquisite patterns, and color combinations can instantly attract consumers' attention and stimulate their desire to purchase. From a marketing perspective, packaging boxes carry brand concepts and product information, serving as an important carrier for brand image communication and helping products stand out in fierce market competition. Today, with the growing awareness of environmental protection, green and environmentally friendly packaging materials and designs have become a new trend in the industry, meeting functional needs while also considering sustainable development.
[0003] In the prior art, most packaging boxes include a box body and a carrying handle. The box body is rectangular and has an opening design, and is used to place items. The carrying handle is fixedly connected to the box body and is close to the opening of the box body, and is used by the user to lift the entire box body.
[0004] Regarding the aforementioned technologies, the two ends of the carrying straps are mostly fixed to the box body by adhesive bonding. This connection method is not strong enough, and when the weight of the items inside the box is large, the carrying strap is prone to breaking off from the box body. Therefore, it needs to be improved. Utility Model Content
[0005] To improve the stability of the connection between the carrying strap and the box body, this application provides a load-bearing packaging box.
[0006] The load-bearing packaging box provided in this application adopts the following technical solution:

Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.
[0035] This application discloses a load-bearing packaging box. (Refer to...) Figure 1The packaging box includes a box body 1 and a carrying strap 2. The box body 1 has an opening and forms a rectangular receiving cavity 3 for placing items. In this embodiment, the box body 1 is made of paper material, but other materials, such as plastic, can also be used. The side of the box body 1 near the opening is folded inward to form a folding plate 4, which is located inside the receiving cavity 3. The two ends of the carrying strap 2 are connected to the folding plate 4 by sewing. The material of the carrying strap 2 can be, but is not limited to, plastic, polyester, and nylon. The end of the carrying strap 2 is located between the folding plate 4 and the inner wall of the box body 1. The folding plate 4 is glued to the inner wall of the box body 1. The end of the carrying strap 2 is sewn to the folding plate 4 with needle and thread, and the folding plate 4 is glued to the box body 1, which further fixes the carrying strap 2 between the folding plate 4 and the box body 1, thereby improving the connection stability between the carrying strap 2 and the box body 1 and reducing the possibility of the carrying strap 2 breaking off from the box body 1.
[0036] The folding plate 4 has two slits 5, with the two ends of the carrying strap 2 positioned within each slit 5. The slits 5 allow space for the ends of the carrying strap 2 to connect to the folding plate 4. Specifically, the inner wall of the box body 1 is coated with a waterproof layer. This waterproof layer forms a waterproof barrier on the surface of the box, reducing the impact of moisture on the packaging material, maintaining the shape and structural stability of the box, preventing distortion, bending, and other deformations, ensuring the box maintains a neat appearance, extending its lifespan, and allowing it to remain in good condition for longer during storage and display. The outer surface of the box body 1 is coated with a paint layer, which gives the surface a glossy finish. This gloss reflects light, making the box look brighter and more refined, enhancing its overall texture and giving it a high-end, luxurious feel. The outer surface of the box body 1 is also decorated with decorative patterns, which enhance its aesthetic appeal. In this embodiment, the decorative pattern is a brand logo, which serves as a brand promotional element.
[0037] In some embodiments, the bottom of the box 1 adopts a honeycomb core structure. The hexagonal structure of the honeycomb core gives it high compressive strength in all directions in the plane, allowing the bottom to withstand greater pressure without easily deforming. Protective pads 6 are provided on the edges of the box 1 along its height direction. The box 1 has four edges along its height direction; the protective pads 6 are made of an elastic material, such as rubber or sponge, and have an L-shaped cross-section. Since several edges of the box 1 are prone to contact and collision with the outside environment, the design of the protective pads 6 can protect these edges and reduce damage to the box 1 caused by impacts.
[0038] Reference Figure 2In addition, in other embodiments, a baffle 7 is rotatably connected to the box body 1. Two baffles 7 are symmetrically arranged along the height direction of the box body 1, and both baffles 7 are located within the receiving cavity 3. The baffle 7 is rectangular, with one end connected to the inner wall of the box body 1 and the other end moving in an arc. The axis of rotation of the baffle 7 is along the width direction of the box body 1 and close to the opening of the box body 1; when an item is placed in the receiving cavity 3, the baffle 7 is used to block the opening of the box body 1.
[0039] When packaging items, first rotate the baffle 7 so that it is outside the receiving cavity 3. Then place the items inside the receiving cavity 3, and finally place the baffle 7 over the top of the items to provide cover and reduce external dust contamination. When the packaging box is not in use, the baffle 7 is inside the receiving cavity 3 and will not affect the overall appearance of the packaging box.
[0040] The implementation principle of a load-bearing packaging box according to an embodiment of this application is as follows: the end of the carrying strap 2 is firmly fixed to the folding plate 4 using a needle and thread sewing process. Simultaneously, the folding plate 4 is tightly connected to the box body 1 through a bonding method, thereby securing the carrying strap 2 firmly between the folding plate 4 and the box body 1. This connection method effectively enhances the connection stability between the carrying strap 2 and the box body 1, ensuring that the carrying strap 2 is not easily detached or loosened during use, providing a reliable guarantee for the normal use of the product.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
