Description

Technical Field

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

[0002] Corrugated cardboard boxes are a type of packaging box made by laminating shaped core paper and linerboard together. They are then processed through die-cutting, creasing, stapling, or gluing. For over half a century, corrugated cardboard boxes have gradually replaced traditional transport packaging containers such as wooden crates, becoming the mainstay of transport packaging due to their superior performance and ease of processing. For example:

[0003] Chinese Patent Publication No. CN219651603U discloses a moisture-proof corrugated cardboard box. The moisture-proof corrugated cardboard box includes a box body, a moisture-proof mechanism, and a fastening mechanism. The moisture-proof mechanism is connected to the bottom end of the box body. The moisture-proof mechanism includes a bottom frame and plastic films. The bottom end of the box body is embedded in the bottom frame and interference-fitted with it. Two symmetrically distributed plastic films are adhered to the upper inner wall of the bottom frame. This utility model features a moisture-proof mechanism. The interference fit between the bottom frame and the box body prevents the cardboard bottom frame from easily detaching. The bottom frame separates the box from the bottom contact surface, preventing direct contact with water and greatly improving the box's moisture-proof capability. Furthermore, the through-groove on the lower inner wall of the bottom frame reduces the contact area between the bottom frame and water, enhancing the bottom frame's moisture resistance. The two staggered plastic films isolate the bottom end of the box, preventing water from affecting it and further improving the box's moisture-proof effect. The presence of the bending plate 11 increases the strength of the cardboard box.

[0004] Based on existing solutions and actual production and processing, current corrugated cardboard boxes still have some problems, such as:

[0005] 1. When moisture-proofing corrugated cardboard boxes, the bottom frame, plastic film, and rubber pads are used to protect the box from moisture. However, since the plastic film and rubber pads protect the bottom of the box, the moisture-proofing effect on other parts of the box is limited.

[0006] 2. When the strength of corrugated cardboard boxes is improved, bending plates are used. However, the bending plates have limited effect on improving the strength of corrugated cardboard boxes, which can lead to deformation and breakage. Therefore, this utility model provides a moisture-proof corrugated cardboard box to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a moisture-proof corrugated cardboard box to solve the problems mentioned in the background art. When moisture-proofing corrugated cardboard boxes involves using a bottom frame, plastic film, and rubber pads, the moisture-proofing effect on other parts of the box is limited because the plastic film and rubber pads only protect the bottom. Furthermore, while bending plates are used to improve the strength of the corrugated cardboard box, their strength-enhancing effect is limited, leading to deformation and breakage.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof corrugated cardboard box, comprising a corrugated cardboard box body, with a cardboard box cover provided on its upper side;
