Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically to a shock-resistant and detachable packaging carton. Background Technology

[0002] Cardboard box packaging refers to the packaging of products using paper boxes during the distribution process to protect the products, facilitate storage and transportation, and promote sales. Cardboard box packaging is one of the most widely used packaging methods. Unlike wooden crates, woven bags, cloth bags, and plastic boxes, cardboard box packaging is lightweight, easy to print, easy to design and form, and inexpensive, making it widely used for both sales and transport packaging of goods.

[0003] A known Chinese patent (application number: CN202420016303.1) discloses a portable packaging carton, relating to the field of packaging carton technology. It includes a carton body and a lifting component. The carton body has a through hole communicating with its interior. Both ends of the lifting component pass through the through hole into the carton body, and both ends of the lifting component are connected to anti-detachment parts. The cross-sectional area of ​​the anti-detachment parts is larger than the opening area of ​​the through hole. This application allows the lifting component to be hung on the hand, fingers, or wrist, carrying the carton by hand, allowing the operator to keep their other fingers or hand free for other operations. Simultaneously, the lifting component allows the operator to carry the carton by hand, which, compared to carrying or holding it with both hands, frees up one hand and is relatively less strenuous and easier.

[0004] However, in implementing the relevant technology, the following problems were found with the aforementioned portable packaging carton: Existing packaging cartons are usually not easy to disassemble, and users may need to use knives or other tools to open the carton, which increases the difficulty of operation and safety hazards. The carton cannot be disassembled and reassembled, making it difficult for users to use it for other purposes, which reduces its added value. Furthermore, existing packaging cartons lack impact resistance, and therefore the carton cannot effectively absorb impact force, which may cause the contents to break or be damaged during transportation. Therefore, an impact-resistant and detachable packaging carton is proposed. Utility Model Content

The carton cannot be disassembled and reassembled, making it difficult for users to use it for other purposes, reducing added value. In addition, existing packaging cartons lack shock resistance, so the carton cannot effectively absorb impact force, which may lead to the breakage or damage of the contents during transportation.

[0006] The technical solution of this utility model is as follows: a shock-resistant and detachable packaging carton, comprising: a U-shaped carton board;

[0007] The U-shaped cardboard box is slidably connected by grooves opened on both sides of the inner wall of the box, and triangular plates are provided at the four corners of the outer wall of the U-shaped cardboard box.

[0008] The double-walled cardboard, pearl cotton, and thickened kraft paper are disposed on the U-shaped cardboard board and the outer wall of the cardboard board, with the pearl cotton located between the double-walled cardboard board and the thickened kraft paper.

[0009] Preferably, a cover plate is placed on the top of the U-shaped cardboard box, and strip plates are fixedly installed on both sides of the cover plate.

[0013] Preferably, the U-shaped cardboard board and the inner wall of the cardboard board are coated with a moisture-proof coating, specifically a nano-water-repellent agent.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] During disassembly, the cardboard is pulled upwards, allowing it to slide upwards through a groove and disassemble. Items inside the U-shaped cardboard can then be retrieved without the need for knives or other tools. After retrieving the items, the cardboard can be inserted back into the groove to reassemble it for reuse. The double-walled cardboard, with its composite structure of two layers of corrugated core paper and three layers of outer paper, provides excellent compression and impact resistance, protecting the contents. The use of pearl cotton significantly enhances cushioning, absorbing impacts. Furthermore, the thickened kraft paper, with its tough texture, long fibers, and tear resistance, effectively protects the contents. Attached Figure Description
