Description

Technical Field

[0001] The utility model belongs to the technical field of packaging cartons, and in particular relates to a high-strength buffer-type packaging cartons. Background Art

[0002] At present, when fragile items are placed inside a carton for transportation, if the carton falls during transportation or collides with other objects, the impact force transmitted to the inside of the carton can easily cause damage to the fragile items inside, and when a sharp object collides with the side wall of the carton, it can easily penetrate into the carton and damage the items inside the carton. Among them, the "high-strength cushioning packaging carton" disclosed in the application number "CN202223220251.X" is also an increasingly mature technology. By arranging multiple arc plates arranged alternately and staggered inside the buffer cavity, the arc plates can be used to cushion the carton when it is impacted. Initial buffering is performed, and at the same time, the inner cavity and the buffer cavity are connected to each other through the connection of the through hole. When a sharp object pierces the inner cavity, the impact force can be buffered under the buffering action of the buffer rubber airbag, and it is buffered in conjunction with the cardboard frame, thereby improving the overall strength of the packaging carton. However, the device also has the following defects: in actual use, multiple components need to be bonded in advance, which is not convenient for quickly combining cardboard into a box body, affecting large-scale assembly line production. After the carton is stored for a long time, it will become damp and soften, affecting the hardness of the carton, and seriously affecting the service life and impact resistance of the carton. After placing items in the carton, there is a lack of load-bearing support structure for multiple boxes to be stacked easily. Utility Model Content
