Description

Technical Field

[0001] This utility model relates to the field of paper box technology, specifically a reinforced paper box. Background Technology

[0002] Cardboard boxes are widely used in the sales packaging of food, pharmaceuticals, and electronics products. They are characterized by low processing costs and convenient storage and transportation, making them particularly suitable for automated packaging and display. Folding cardboard boxes, due to their flat transport characteristics, can significantly reduce logistics costs and are also suitable for the sealed packaging of liquid goods such as juice and milk. Cardboard box materials are easily recyclable and biodegradable, aligning with environmental trends; their lightweight design reduces transportation energy consumption, and their reuse can lower living costs.

[0003] A search revealed Chinese utility model patent CN222023044U, "A Reinforced Cardboard Box." This utility model relates to the field of cardboard box technology and includes a cardboard box body. A reinforcement component is installed inside the cardboard box body. A limiting component and a fixing component are respectively installed inside and on the top of the reinforcement component. The fixing component includes a fixing plate A, a fixing plate B, a movable block, and a limiting block. A groove is formed at the center of the top of the fixing plate B. The advantage of this utility model is that by setting up the fixing plate A, fixing plate B, movable block, and limiting block, the movable block is moved outward, and then the fixing plates A and B are flipped, so that the fixing plates A and B are at the same horizontal height. The inertia of the telescopic spring is used to move the limiting block into the groove, causing the fixing plates A and B to interlock. This effectively protects the items inside the cardboard box, preventing damage during handling or movement.

[0004] Existing devices have the following problems when in use: During transportation, the cardboard box is damaged by collisions, and the contents inside are also damaged. Usually, an internal structure is added to the inside of the cardboard box to reduce the damage to the cardboard box and its contents.
