Description

Technical Field

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

[0002] Currently, corrugated cardboard is widely used as packaging for various commodities due to its light weight, low price, simple production, wide range of uses, and recyclability, and has become one of the main materials for making packaging containers that has experienced rapid development to date. Chinese patent CN216581831U discloses a moisture-resistant and shock-proof corrugated cardboard box, aiming to solve the problem that existing cardboard boxes have overly simple structures and poor moisture resistance, allowing moisture to easily enter the corrugated cardboard box during use, damaging the box structure and affecting its service life. The key technical points are: it includes a cardboard box body, with multiple waterproof strips at the bottom, protective strips at the four corners, and two top covers. The inner wall of the cardboard box body has mounting grooves containing a desiccant. The cardboard box body includes corrugated paper and inner and outer corrugated paper layers respectively disposed on both sides of the corrugated paper, with a waterproof coating on the surface of the outer corrugated paper layer. This invention only has waterproof strips at the bottom, effectively preventing the corrugated paper from getting damp.

[0003] While the corrugated cardboard boxes described in the aforementioned patents improve the moisture-proof performance of the boxes to some extent, their structural design still needs improvement. For example, the waterproof strip is only placed inside the cardboard box, which provides relatively weak protection for the bottom of the box. Moisture may still seep through the bottom, affecting the overall service life of the cardboard box. In addition, the desiccant installation slot is located on the inner wall and is fixed, making it impossible to flexibly replace or add according to actual usage needs, resulting in poor ease of use. Utility Model Content

[0004] The purpose of this invention is to provide a bottom-resistant corrugated cardboard box, which strengthens the bottom of the box and allows the melamine board to be replaced with more suitable waterproof and moisture-proof materials depending on the usage environment, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottom moisture-resistant corrugated cardboard box, comprising a corrugated cardboard box, a reinforced base plate provided at the lower end of the corrugated cardboard box, a connecting groove provided on the reinforced base plate at a corresponding position on the corrugated cardboard box, and an adhesive application groove provided at the lower end of the reinforced base plate, wherein a melamine board is provided on the adhesive application groove, and a cap is provided at the upper end of the corrugated cardboard box.

[0006] Preferably, a support strip base is provided at the upper end of the melamine board, and the support strip base is bonded to the melamine board.

[0007] Preferably, the support bar base is provided with a support bar, and the support bar and the support bar base are integrally formed.

[0008] Preferably, the reinforced chassis has a front-end outer fixing block on one side of the connecting groove, and the front-end outer fixing block is integrally formed with the reinforced chassis.

[0009] Preferably, the reinforced chassis is provided with side outer fixing blocks on both sides of the connecting groove.

[0010] Preferably, the connecting groove has a front inner fixing block on the side away from the front outer fixing block.

[0011] Preferably, the connecting groove has an inner side fixing block on the side away from the outer side fixing block.

[0012] Preferably, a fixing bolt is provided on the inner side fixing block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a reinforced base at the bottom of the corrugated cardboard box, replacing the original paper bottom. This not only strengthens the bottom of the box but also utilizes a stacked and bonded structure. The reinforced base contains a melamine board, which is inherently strong and moisture-proof, effectively preventing moisture from entering the box.

[0014] By setting a support strip base at the top of the melamine board, and setting multiple support strips on the support strip base, the support strips can lift up the items inside the corrugated cardboard box. Even if the corrugated cardboard box is invaded by liquid, causing the liquid to accumulate on the support strip base, it can prevent the objects from directly contacting the liquid.
