[0002] Corrugated cardboard, also known as corrugated paperboard, is made by gluing at least one layer of corrugated paper and one layer of linerboard (also called boxboard). It exhibits good elasticity and extensibility. It is primarily used to manufacture cartons, cardboard inserts, and other packaging materials for fragile goods. It is primarily made from traditional straw pulp and waste paper, which is beaten to create a base similar to yellow cardboard. This is then machined and rolled into a corrugated shape. The surface is then bonded to the linerboard with adhesives such as sodium silicate.

[0003] In the prior art: Patent publication number CN202321775499.4 discloses a moisture-proof corrugated paper packaging box, comprising a box body, wherein thickened portions are provided at the edges on both sides of the lower side of the box body, wherein the thickened portions include a first supporting corrugated portion fixed to the outer surface of the box body, an intermediate layer fixed to the side of the first supporting corrugated portion away from the box body, a second supporting corrugated portion fixed to the side of the intermediate layer away from the first supporting corrugated portion, and an outer layer supporting portion fixed to the primary side of the second supporting corrugated portion away from the intermediate layer;

[0004] The above-mentioned corrugated paper packaging box still has some problems in actual use. For example, the entire box body is still designed with corrugated paper, which has poor moisture-proof effect. After being damp, the entire packaging box softens, which will deteriorate the structural stability of the packaging box and lead to scrapping. For this reason, we propose a moisture-proof corrugated paper packaging box. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 , this embodiment provides a technical solution: a moisture-proof corrugated paper packaging box, comprising an outer packaging box 1 and a moisture-proof mechanism 2;

[0023] Outer packaging box 1: a corrugated box 4 is adhered to its interior, and an upper cover 7 is provided on the upper end of the corrugated box 4. The outer packaging box 1 is an EVA foam pad. When the corrugated paper packaging box is needed, the upper cover 7 can be manually opened to put the goods to be packaged into the interior of the corrugated box 4;

[0024] Moisture-proof mechanism 2: It includes an outer rubber strip frame 21, an inner rubber strip frame 22, a rubber connecting strip 23 and a honeycomb panel 24. The outer rubber strip frame 21 is fixedly connected to the outer surface of the outer packaging box 1, the inner side wall of the inner rubber strip frame 22 is fixedly connected to the outer surface of the corrugated box 4, the outer surface of the inner rubber strip frame 22 is fixedly connected to the inner side wall of the outer packaging box 1, the inner lower side of the outer rubber strip frame 21 is fixedly connected to the honeycomb panel 24, and the inner wall of the honeycomb panel 24 is fixedly connected to the outer surface lower side of the outer packaging box 1. The side is fixedly connected, and the moisture-proof mechanism 2 also includes a rubber connecting strip 23, which is fixedly connected between the inner side wall of the outer rubber strip frame 21 and the outer surface of the inner rubber strip frame 22. The side wall of the outer packaging box 1 is provided with evenly distributed avoidance grooves 5, and the inner walls of the four avoidance grooves 5 are respectively fixedly connected to the outer surface of the rubber connecting strip 23 on the same side. The lower side wall of the outer rubber strip frame 21 is fixedly connected with a bottom support strip 6 symmetrically on the left and right. The middle part of the left side wall of the outer rubber strip frame 21 is fixedly connected to the outer surface of the rubber connecting strip 23. When the packaging box is placed on a relatively humid placement surface, the honeycomb panel 24 will first support the outer packaging box 1, and also prevent the moisture on the humid placement surface from invading the outer packaging box 1 and the corrugated box 4. At the same time, the bottom support bar 6 can realize flexible contact with the placement surface to further protect the entire packaging box.

[0025] The working principle of the moisture-proof corrugated paper packaging box provided by the present invention is as follows: when the corrugated paper packaging box needs to be used, the upper cover 7 can be manually opened to put the goods to be packaged into the interior of the corrugated box 4. At this time, the staff can move the corrugated paper packaging box at will by the lifting handle 3. When the staff lifts the corrugated paper packaging box, the lifting force will be dispersed to the outside of the entire outer rubber strip frame 21 through the lifting handle 3, and then absorbed by the outer rubber strip frame 21 and the inner rubber strip frame 22, preventing the lifting force from being directly absorbed by the corrugated box 4. After the corrugated box 4 is filled with goods, the entire packaging box can be sealed with tape. At this time, when the packaging box is invaded by external moisture, the EVA foam material of the outer packaging box 1 will block the moisture to prevent the moisture from further invading the corrugated box 4 and then wetting the corrugated box 4. When the packaging box is placed on a relatively humid placement surface, the honeycomb panel 24 will first support the outer packaging box 1, and will also block the moisture from the humid placement surface from invading the outer packaging box 1 and the corrugated box 4. At the same time, the bottom support bar 6 realizes flexible contact with the placement surface to further protect the entire packaging box.
