Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, specifically a high-strength moisture-proof corrugated cardboard box. Background Technology

[0002] The core material of corrugated cardboard boxes is corrugated cardboard, whose structure includes at least one layer of corrugated core paper and two layers of linerboard, which are bonded together to form a multi-layer composite. The manufacturing process includes die-cutting, creasing, nailing or gluing, etc., and finally forming a three-dimensional box. Widely used in the packaging and transportation of goods, it features lightweight, environmental friendliness, excellent compression resistance and cushioning performance; In the existing technology, authorized publication number CN 208377286 U proposes a moisture-proof, high-strength corrugated cardboard box, including a corrugated box assembly, a protective assembly, a label assembly, and a top cover assembly. The corrugated box assembly includes a corrugated box, a handle, a bottom plate, and a support frame. The handle is located on the upper right side surface of the corrugated box, and the corrugated box is glued and fixed to the handle. The bottom plate is located on the lower inner surface of the corrugated box, and the corrugated box is fixedly connected to the bottom plate. The support frame is located on the inner side wall of the bottom plate, and the bottom plate is fixedly connected to the support frame. Although this design can prevent water from seeping into the bottom of the corrugated box, the sealing of the corrugated cardboard box is mostly achieved by overlapping two layers of lids. The strength of the box opening mainly relies on the strength of the corrugated cardboard itself, which can easily lead to deformation at the opening of the corrugated cardboard box during long-term stacking.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: a high-strength moisture-proof corrugated cardboard box, including a corrugated cardboard box body 1;

[0020] Corrugated cardboard box 1: Both its top and bottom ends are open. Outer lids 3 are located at the front and rear ends of the top and bottom surfaces of corrugated cardboard box 1, and inner lids 4 are located at the left and right ends of the top and bottom surfaces of corrugated cardboard box 1. Both outer lids 3 and inner lids 4 are made of corrugated cardboard. A waterproof layer 2 is provided on the outer surfaces of corrugated cardboard box 1, outer lids 3, and inner lids 4. This waterproof layer 2 prevents external moisture from seeping into the corrugated cardboard box, improving its moisture-proof effect. The surface of the inner lid 4 has crease grooves 1-5, 2-6, 3-7, and 4-8 sequentially arranged from the end closest to the center of corrugated cardboard box 1 to the end furthest from the center. The inner lid 4 is then folded along crease grooves 1-5, 2-6, 3-7, and 4-8 in sequence. 6. The inner box cover 4 is bent into a right-angled triangle shape at crease grooves 3 (7) and 4 (8). After packaging, the bent section between crease groove 2 (6) and crease groove 3 (7) is vertical and fits against the inner wall of the corrugated cardboard box 1. The bent section between crease groove 1 (5) and crease groove 2 (6) is horizontal and contacts the outer box cover 3. The inner box cover 4, bent into a right-angled triangle shape, provides stronger support for the outer box cover 3, making the top and bottom openings of the corrugated cardboard box less prone to deformation. It also includes support blocks 9, which are located inside the space formed after the inner box cover 4 is bent. Support blocks 9 are hollow cardboard. The support blocks 9 are inserted into the right-angled triangle shape... Inside the inner box cover 4, to improve the support effect of the inner box cover 4 when bent into a right-angled triangle shape, double-sided adhesive tape 10 is provided at the lower end of the inner box cover 4. After bending, the release paper on the surface of the double-sided adhesive tape 10 is peeled off, and the position of the end of the inner box cover 4 is fixed by the double-sided adhesive tape 10, so that the inner box cover 4 maintains the right-angled triangle bending state. Rubber pads 11 are provided at both ends of the upper surface of the outer box cover 3. The rubber pads 11 are used to make the contact between the outer box cover 3 and the inner box cover 4 tighter, preventing external moisture from entering through gaps and improving the moisture-proof effect. A bendable support cover plate 12 is provided at the end of the outer box cover 3 away from the center of the corrugated cardboard box 1. The support cover plate 12 is inserted into the lateral position. The inner box cover 4 is positioned between the two corresponding inner box covers 4 in the lateral position to provide support and improve the support effect. The distance between crease groove 1 5 and crease groove 2 6 is equal to the distance between crease groove 1 5 and the inner wall of the corrugated cardboard box 1 minus half the thickness of the inner box cover 4. This ensures that after bending, the distance between crease groove 2 6 and the inner wall of the corrugated cardboard box 1 is equal to half the thickness of the cover 4, limiting the left and right position of the inner box cover 4 after bending. This ensures that the bent section located between crease groove 2 6 and crease groove 3 7 is in a vertical state and adheres to the inner wall of the corrugated cardboard box 1. The waterproof layer 2 is an acrylic resin layer, which can be an Ent waterproofing agent. It is environmentally friendly, non-toxic, and easy to operate. It can be directly brushed or sprayed without drying.

[0021] The working principle of the high-strength moisture-proof corrugated cardboard box provided by this utility model is as follows: When using the corrugated cardboard box for packaging, firstly, the inner box cover 4 is bent sequentially along crease groove 1 5, crease groove 2 6, crease groove 3 7, and crease groove 4 8, so that the inner box cover 4 is bent into a right-angled triangle shape. After bending, the release paper on the surface of the double-sided adhesive 10 is peeled off, and the position of the end of the inner box cover 4 is fixed by the double-sided adhesive 10, so that the inner box cover 4 is kept in a right-angled triangle bent state. Then, the inner box cover 4 is rotated 180 degrees so that the inner box cover 4 enters the interior of the corrugated cardboard box body 1. Because the distance from crease groove 1 5 to crease groove 2 6 is equal to the distance from crease groove 1 5 to the inner wall of the corrugated cardboard box body 1 minus half the thickness of the inner box cover 4, the distance from crease groove 2 6 to the inner wall of the corrugated cardboard box body 1 after bending is equal to half the thickness of the box cover 4. The bending section between crease groove 3 and 7 is in a vertical state and fits against the inner wall of the corrugated cardboard box 1. The bending section between crease groove 1 and crease groove 2 is in a horizontal state. Then, the support cover plate 12 is bent to a state perpendicular to the outer box cover 3, and the outer box cover 3 is rotated into the corrugated cardboard box 1. The outer box cover 3 fits against the horizontal surface of the bent inner box cover 4. The inner box cover 4, bent into a right-angled triangle state, provides higher strength support for the outer box cover 3. At the same time, the support cover plate 12 enters between the two inner box covers 4 corresponding to the horizontal position, providing support between the two inner box covers 4 corresponding to the horizontal position, improving the support effect. Finally, the outer box cover 3 is connected to the corrugated cardboard box 1 with tape to complete the packaging. During use, the waterproof layer 2 is used to prevent external moisture from seeping into the interior of the corrugated cardboard box, improving the moisture-proof effect of the corrugated cardboard box.

[0022] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
