Description

Technical Field

[0001] The utility model belongs to the technical field of packaging and printing, and specifically relates to a protective carton. Background Art

[0002] A carton is a packaging container made of paper, typically constructed by gluing together multiple layers of cardboard to create a structure with a certain degree of rigidity and strength. The main materials used for cartons include corrugated cardboard, kraft paper, and whiteboard. Corrugated cardboard is widely used due to its lightweight and excellent cushioning properties. Cartons can be customized into various shapes and sizes and are widely used in packaging, transportation, and storage. With the development of globalization and a market economy, commodity distribution and supply chain management have become increasingly complex. Cartons, with their adaptability and cost-effectiveness, meet diverse packaging needs while also helping to reduce logistics costs. Their light weight and low cost make them suitable for large-scale production and widespread use. During transportation, cartons are often subjected to compression, impact, and friction. The edges of cartons are most directly affected by these external forces, making them susceptible to knocks and damage during loading, unloading, and stacking.

[0003] In summary, when cartons are being transported, their edges are easily bumped or damaged, affecting their appearance. Utility Model Content

[0004] In view of this, the utility model provides a protective carton, which can solve the problem that the edges of the carton are easily bumped or damaged during transportation, thereby affecting the appearance.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a protective carton, which includes a carton, a corner protection assembly and a buffer assembly. The carton is a hollow rectangular structure, which is formed by folding and gluing multiple buffer paper boards and is used to accommodate articles. The corner protection assemblies are arranged at the edges of the outside of the carton, and the corner protection assemblies are fixedly connected to the edges of the carton by glue. The corner protection assemblies are used to reinforce the edges of the carton to prevent bumps. The buffer assembly is provided at the folded edge inside the carton, and the buffer assembly is clamped between the inner wall of the carton and the articles inside the carton. The buffer assembly is used to fill the gap and reduce the impact between the articles and the carton.

[0007] The technical effects of a protective carton provided by the present invention are as follows: by providing a corner protection assembly, the structural strength of the edges of the carton can be improved, external pressure can be effectively dispersed and withstood, the risk of damage to the corners of the box body can be reduced, and by providing additional support and protection, the carton can be effectively prevented from being deformed or damaged at the corners during transportation and stacking. The corner protection assembly can effectively protect the corners of the carton from direct impact, thereby reducing damage caused by collisions. At the same time, it can prevent the corners of the carton from being torn or broken during transportation. By providing a buffer assembly, external shocks and vibrations can be effectively absorbed and dispersed, thereby reducing the direct impact of these forces on the items in the carton. The buffer assembly can form a protective layer inside the carton, so that the packaged contents do not directly contact the inner wall of the carton during transportation or handling, thereby reducing damage caused by bumps or collisions. The buffer assembly can reduce the direct impact of external forces on the edges of the carton, and prevent the carton from being deformed or torn during transportation and handling.

[0008] On the basis of the above technical solution, a protective carton of the present invention can also be improved as follows:

[0009] Among them, the corner guard assembly includes a corner guard plate, transverse reinforcement ribs and longitudinal reinforcement ribs. The corner guard plate is arranged on the outside of the edge of the carton, and the transverse reinforcement ribs and longitudinal reinforcement ribs are arranged on the inside of the corner guard plate. The transverse reinforcement ribs and longitudinal reinforcement ribs are fixedly connected to the corner guard plate. The transverse reinforcement ribs and longitudinal reinforcement ribs are used to enhance the strength and hardness of the corner guard plate.

[0010] Furthermore, the transverse reinforcing ribs are arranged parallel to the long sides of the corner guards, and the transverse reinforcing ribs are used to enhance the ability of the corner guards to resist longitudinal bending. The longitudinal reinforcing ribs are arranged perpendicular to the long sides of the corner guards, and are used to enhance the ability of the corner guards to resist transverse bending.

[0011] Furthermore, the corner guard is an L-shaped structure, and is made by gluing together multiple layers of corrugated cardboard.

[0012] Furthermore, the buffer component includes an airbag, a foam board and a buffer cardboard, the airbag is used to accommodate air and absorb impact force through extrusion deformation, the buffer cardboard is used to absorb impact force through structural deformation, the airbag is sandwiched between the foam board and the buffer cardboard, and the buffer cardboard is bonded to the foam board by glue.

[0013] Furthermore, the airbag includes an airbag membrane and an inflation valve. The airbag membrane is a long strip structure. The end of the airbag membrane is fixedly connected to the inflation valve, and the inflation valve is used to inflate air into the airbag membrane.

[0014] Furthermore, the buffer paperboard is made of three layers of polyethylene foam, polyurethane foam and polystyrene foam.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: polyethylene foam has good cushioning performance and chemical corrosion resistance; polyurethane foam has high resilience and impact resistance; polystyrene foam has good cushioning performance and thermal insulation performance.

[0016] Furthermore, the foam board is made of multi-layer corrugated cardboard.
