Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically to an anti-collision and pressure-resistant cardboard box. Background Technology

[0002] Cardboard boxes are packaging containers made primarily of cardboard (such as corrugated paper, kraft paper, etc.). They are widely used in commodity transportation, warehousing, and display. They have the characteristics of protecting goods, facilitating handling, and being environmentally friendly and recyclable. Cardboard boxes themselves have low cost and are easy to seal, making them suitable for product transportation, material handling, etc. They are a common packaging facility in people's lives.

[0003] Cardboard boxes, as the core carrier of modern packaging, combine functionality and economy. Their diverse designs and material choices can meet the needs of different scenarios. Nowadays, cardboard boxes are most commonly used as warehousing packaging products. During logistics transportation, there are often external impacts, which can easily cause cardboard boxes to deform. In severe cases, this can damage the items stored inside. Utility Model Content

After the release paper is removed, the double-sided adhesive layer is exposed. Then, plastic strips are attached to the edges of the main body of the carton, and right-angled ends are formed on the plastic strips. Therefore, the right-angled ends can be adapted to the right angles of the edges. In this way, the plastic strips support the exterior of the main body of the carton, effectively reducing the deformation caused by compression during transportation and improving the overall external deformation resistance.

[0015] The bottom support plates are bonded together with a connecting adhesive layer. The bottom support plates are bonded to the bottom of the carton body using the connecting adhesive layer. Therefore, the bottom of the carton body is supported by two stacked bottom support plates. A first wave sandwich layer is bent and distributed in the bottom support plates.

[0016] The main body of the carton is made of folded cardboard. An inner core cardboard is fixed in the center of the cardboard, and a second wave sandwich is fixed at the top and bottom of the inner core cardboard. The second wave sandwich is designed in a bent shape, so it can improve the strength of the carton body. This achieves the purpose of improving the strength of the carton body and reducing the deformation problem of the carton body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An embodiment of this utility model provides: a shockproof and pressure-resistant cardboard box, including a cardboard box body 1, a bottom support plate 3 stacked and installed on the bottom surface inside the cardboard box body 1, a connecting adhesive layer 2 for bonding and fixing coated on the bottom support plate 3, a solid layer 4 formed in the bottom support plate 3, a first corrugated interlayer 5 fixed in the solid layer 4, a plastic strip 6 assembled on the right-angle side of the cardboard box body 1, a right-angle end 7 formed on the plastic strip 6 matching the right-angle side, a double-sided adhesive layer 8 fixed on the right-angle end 7, and a release paper 9 connected to the outside of the double-sided adhesive layer 8.

[0024] The right-angle end 7 is right-angled and matches the right-angled edge of the carton body 1.

[0025] The plastic strips 6 are symmetrically distributed about the central axis of the carton body 1, and the length of the plastic strips 6 is adapted to the size of the carton body 1.

[0026] One side of the double-sided adhesive layer 8 is bonded and fixed to the right-angle end 7, and the other side of the double-sided adhesive layer 8 is connected to the release paper 9.

[0027] The two bottom support plates 3 are bonded and fixed together by a connecting adhesive layer 2, and the bottom support plate 3 is bonded and fixed to the bottom of the carton body 1 by the connecting adhesive layer 2.

[0028] The main body of the carton 1 is made of folded cardboard, and an inner core cardboard 11 is fixed in the middle of the cardboard body 1.

[0029] The inner core paperboard 11 has a second corrugated interlayer 10 fixed at its upper and lower positions. The second corrugated interlayer 10 is bent and symmetrically distributed about the transverse axis of the inner core paperboard 11.

[0030] The first wave interlayer 5 is bent inside the bottom support plate 3, and the outer wall of the carton body 1 is coated with a waterproof layer.

[0031] Furthermore, the outer wall of the carton body 1 is coated with a waterproof layer, which can be a waterproofing agent, waterproof coating, plastic film, nano-coating, etc.

[0032] Applying a layer of waterproofing agent and then drying it can form a thin film with high transparency and gloss, enhancing waterproof and moisture-proof performance;

[0033] Water-based or oil-based waterproof coatings form a waterproof layer. This coating treatment can be applied to one or both sides, depending on the requirements.

[0034] This process involves laminating a polypropylene or other plastic film onto the surface of the cardboard box using a laminating process, and then bonding them together with an adhesive under heat and pressure. The laminated cardboard box has a glossy, abrasion-resistant surface and a degree of water resistance.

[0035] One method involves coating the surface of the cardboard box with a nano solution, which creates a nano coating with strong waterproof properties, making it suitable for packaging that requires high waterproof performance.

[0036] A solid layer 4 is formed in the bottom support plate 3, and a first wave interlayer 5 is fixed in the solid layer 4. The solid layer 4 can be filled with paper material to fix the position of the first wave interlayer 5.

[0037] Working principle: First, during operation, the main body 1 of the carton is folded from cardboard. Before folding, the two bottom support plates 3 are glued and fixed together with the connecting adhesive layer 2. The bottom support plate 3 is glued and fixed to the bottom of the carton main body 1 using the connecting adhesive layer 2. Therefore, the bottom of the carton main body 1 is supported by two stacked bottom support plates 3. The first wave interlayer 5 is bent and distributed in the bottom support plate 3. The bottom is supported by the cooperation of the two bottom support plates 3 and the first wave interlayer 5. After folding, eight edges are formed on the top and bottom, and four edges on the sides. After tearing off the release paper 9, the double-sided adhesive layer 8 is exposed. Then, the plastic strip 6 is attached to the edge of the carton main body 1. The plastic strip 6 forms a right angle end 7. Therefore, the right angle end 7 can be matched with the right angle of the edge. The plastic strip 6 is used to support the outside of the carton main body 1.
