Technical Field

[0001] The utility model relates to the field of paper boxes, in particular to a paper box with strong support Background Art

[0002] Paper boxes are usually used as packages for commodities or outer protective layers for items. The volume of a paper box changes according to the size of the commodity. There are usually various pattern or text prompts on paper boxes, such as "Handle with Care", "Keep Dry", "This Side Up", "Stacking Limit", "Protect from Sun", "Moisture Proof", "Quality Safety", "Do Not Tumble", "Do Not Trample", "Attention to Fire", "Fragile Items", "Environmental Greening", "Protect from Heat", "Food", "Anti-odor", etc., to remind users and protect the items inside from damage. Commonly used paper boxes have three layers or five layers, and seven-layer ones are used less frequently. Each layer is divided into inner paper, corrugated paper, core paper, and face paper.

At the same time, it can also prevent the sharp parts of the items from hitting the corners and causing damage to the carton, and the auxiliary components 4 can reinforce the side plates of the carton, thereby further enhancing the overall support force of the carton.

[0050] The cross-section of the corner support bar frame 3 is a triangular structure.

[0051] The triangular structure has strong support force and can stably support the corners of the carton, thereby increasing the support force of the carton.

[0052] In this technical solution, the corner support bar frames 3 are used to provide support for the corners of the carton.

[0053] The auxiliary component 4 includes a buffer cotton strip 41, and the buffer cotton strip 41 is detachably placed inside the corner support bar frame 3.

[0054] In this technical solution, the buffer cotton strip 41 can endow the corner support strip frame 3 with a certain buffering function, and can protect both the object and the corner of the carton at the same time.

[0055] The buffer cotton strip 41 is detachably installed inside the corner support strip frame 3. The buffer cotton strip 41 can reduce the impact force from the items inside the carton and the impact force from the outside of the carton, reducing the probability of carton damage and facilitating the use of the carton.

[0056] The auxiliary component 4 further includes a reinforcing frame 42. A reinforcing frame 42 is arranged between adjacent corner support strip frames 3, and both ends of the reinforcing frame 42 are respectively in contact with one side of the corner support strip frame 3.

[0064] The first support strip columns 8 and the second support strip columns 9 are respectively arranged on both sides of the support layer board 7, and the first support strip columns 8 and the second support strip columns 9 are arranged in a staggered manner.

[0065] In this technical solution, the first support strip columns 8 and the second support strip columns 9 can further increase the structural strength of the carton board 2.

[0066] A plurality of reinforcing rib strips 10 are connected inside both the inner layer board 5 and the outer layer board 6, and adjacent two reinforcing rib strips 10 are connected to each other;

[0067] The reinforcing rib strip 10 is of a hollow structure, and the cross-section of the reinforcing rib strip 10 is in a regular hexagon structure.

[0068] In this technical solution, the reinforcing ribs 10 can be used to increase the structural strength of the inner layer board 5 and the outer layer board 6 respectively. At the same time, due to the hollow design, the weight of the cardboard box can be reduced.

[0069] The first support bar columns 8 and the second support bar columns 9 distributed in an alternating manner can increase the structural strength of the cardboard box board 2. At the same time, the support layer board 7 enables the cardboard box board 2 to have a certain buffering performance.

[0070] Moreover, the reinforcing ribs 10 can increase the structural strength of the inner layer board 5 and the outer layer board 6. At the same time, due to the hollow design, the weight of the cardboard box board 2 can be reduced, thus facilitating the transportation and use of the cardboard box.
