Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard box technology, and more specifically, it relates to an environmentally friendly high-strength corrugated cardboard box. Background Technology

[0002] Corrugated cardboard boxes are packaging containers made from corrugated cardboard. They are composed of multiple layers of cardboard with a corrugated core providing cushioning and support. They offer advantages such as light weight, low cost, ease of processing, and recyclability, making them environmentally friendly. Furthermore, their strength can be enhanced through strategic structural design to meet the packaging needs of various items. Widely used in logistics, transportation, and retail, they are an important product in the modern packaging industry.

[0003] Based on the above, the inventors have discovered the following problems: When using current corrugated cardboard boxes, since items need to be placed inside the box, the top and bottom sides of the box are provided with openings and flip-up covers. After the items are placed inside the box, the covers are closed and sealed. However, in order to make the box easy to open, the covers are mostly fixed with tape, which results in low strength in the cover area.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide environmentally friendly high-strength corrugated cardboard boxes, in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an environmentally friendly, high-strength corrugated cardboard box, thus solving the problem of low strength in the cover area of ​​current corrugated cardboard boxes.

[0006] The purpose and effectiveness of this environmentally friendly high-strength corrugated cardboard box are achieved through the following specific technical means:

[0007] An environmentally friendly, high-strength corrugated cardboard box includes a main body, which includes a box body. A pair of flip-up covers are installed on the upper and lower sides of the box body. Thickened portions are installed on the surface of the covers. When the covers are closed, three sides of the thickened portions contact the inner wall of the box body.

[0008] Furthermore, the connection between the box body and the cover is integral, and the connection is provided with creases to facilitate the flipping of the cover.

[0009] Furthermore, two of the inner walls of the housing are fitted with support portions, the upper and lower ends of which are in contact with the thickened portion.

[0010] Furthermore, the main body of the carton is made of corrugated board, which includes a face paper layer and a core layer. The face paper layer is laminated on the upper and lower sides of the core layer, and the core layer has a wavy structure.

[0011] Furthermore, the core layer is made of plastic, specifically polyethylene or polypropylene.

[0012] Furthermore, the outer surface of the face paper layer is coated with a waterproof coating, which is an environmentally friendly water-based polyurethane waterproof coating with a thickness of 0.05-0.2 mm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When in use, the thickened and supporting parts of this invention can effectively support the cover plate, thereby greatly improving the compressive strength of the carton cover plate. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides an environmentally friendly high-strength corrugated cardboard box, including a cardboard box body 1. The cardboard box body 1 includes a box body 2. The length, width and height of the box body 2 can be customized. The box body 2 is a hollow cuboid with openings at the top and bottom. A pair of cover plates 3 are installed on the top and bottom sides of the box body 2. When the pair of cover plates 3 are closed, they can seal the opening of the box body 2. A thickened part 4 is installed on the surface of the cover plate 3. When the cover plate 3 is closed, three sides of the thickened part 4 are in contact with the inner wall of the box body 2.

[0028] When in use, first close one of the pairs of covers 3 and secure them with tape. Then place the items to be placed in the box 2 and close the top cover 3. When the surface of the thickened part 4 on the same side as the connection between the cover 3 and the box 2 comes into contact with the inner wall of the box 2, the box 2 can provide support for the thickened part 4, thereby providing support for the cover 3 and improving the compressive strength of the cover 3.

[0029] The connection between the box body 2 and the cover plate 3 is an integral piece, and the connection is provided with creases to facilitate the flipping of the cover plate 3.

[0030] In some embodiments, support portions 5 are installed on the surfaces of two opposing inner walls of the housing 2. These inner walls are not connected to the cover plate 3, and both the upper and lower ends of the support portions 5 are in contact with the thickened portions 4.

[0031] With the use of the support part 5, when the cover plate 3 is closed, the thickened part 4 comes into contact with the support part 5, and the support part 5 provides a supporting force to the thickened part 4, thereby providing a supporting force to the cover plate 3 and further improving the compressive strength of the cover plate 3.

[0032] The main body 1 of the carton is made of corrugated board, which includes a face paper layer 101 and a core layer 102. The face paper layer 101 is laminated on the upper and lower sides of the core layer 102, and the core layer 102 has a wavy structure. The wavy core layer 102 has high compressive strength.

[0033] In some embodiments, the core layer 102 is made of plastic, specifically polyethylene or polypropylene. Plastic core layers offer higher strength compared to paper core layers 102.

[0034] In some embodiments, the outer surface of the face paper layer 101 is coated with a waterproof coating 6, which is an environmentally friendly water-based polyurethane waterproof coating, and the thickness of the waterproof coating 6 is 0.05-0.2 mm.

[0035] The use of waterproof coating 6 can improve the overall waterproofness of the carton body 1.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
