[0002] Corrugated cardboard is the most widely used packaging product, consistently leading the way in terms of usage. For over half a century, thanks to its superior performance and processability, corrugated cardboard has gradually replaced wooden crates and other transport containers, becoming the mainstay of transportation packaging. In addition to protecting goods and facilitating storage and transportation, corrugated cardboard also enhances and promotes products. Corrugated cardboard is a green and environmentally friendly product, contributing to its environmental benefits and ease of handling and transportation.

[0003] The bottom plates of most existing cartons are fixed by snap-fitting and splicing. However, both conventional cartons in the prior art and some functional cartons often have insufficient bottom bearing capacity. When heavy items are stored in the carton and carried, the bottom plate of the carton will be deformed due to the heavy items inside the carton, resulting in insufficient support capacity for the items inside the box, which can easily lead to the bottom of the packaging carton breaking, and even causing the items in the carton to be too heavy and fall out of the carton. In order to avoid this situation, a moisture-proof carton with a bottom reinforcement is proposed to solve the above problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a moisture-proof carton with a bottom reinforcement. By arranging a reinforcement buffer at the bottom of the carton, the supporting effect of the bottom of the carton can be improved and there will be a certain buffering capacity when bearing weight, thereby preventing the bottom of the carton from deforming and affecting the supporting effect of the bottom plate.

[0005] The technical solution for achieving the purpose of the utility model is: a moisture-proof carton with a bottom reinforcement, comprising a box body, an inner bottom wall of the box body is provided with a foam frame, the inner wall of the foam frame is provided with four grooves, the inner walls of multiple grooves are bonded with limiting strips, the inner walls of multiple limiting strips are slidably connected to limiting blocks, the opposite surfaces of multiple limiting blocks are fixedly connected to the same bottom plate, the inner bottom wall of the foam frame is provided with a polyethylene foam buffer layer, the upper surface of the polyethylene foam buffer layer is provided with a connecting cardboard, the upper surface of the connecting cardboard is bonded with multiple arched buffer layers, and the bottom plate is arranged above the arched buffer layer.

[0006] In some embodiments, a paper frame is bonded to the upper surface of the bottom plate, a plurality of engaging notches are formed on the upper surface of the paper frame, and inner walls of the plurality of engaging notches are slidably connected to longitudinal paperboards.

[0007] In some embodiments, the upper surfaces of the plurality of longitudinal paperboards are provided with a plurality of engaging notches, the inner walls of the plurality of engaging notches are slidably connected to transverse paperboards, and the upper surfaces of the transverse paperboards are provided with placement plates.

[0008] In some embodiments, a moisture-proof component is provided on the lower surface of the box;

[0009] The moisture-proof component includes a moisture-proof leg, the upper surface of the moisture-proof leg is provided with an adhesive layer, and the moisture-proof leg is connected to the lower surface of the box through the adhesive layer.

[0010] In some embodiments, a dovetail groove is formed on the lower surface of the moisture-proof leg, a dovetail block is slidably connected to the inner wall of the dovetail groove, and a rubber pad is fixedly connected to the lower surface of the dovetail block.

[0011] In some embodiments, two cover plates are provided on the upper surface of the box.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] The utility model uses the polyethylene foam buffer layer and the arched buffer layer arranged inside the box body to have a buffer effect on the bottom of the box body when heavy objects are placed inside the box body, thereby preventing the bottom of the box body from being deformed and affecting its supporting effect. At the same time, the cross-fixing method of the horizontal cardboard and the vertical cardboard arranged above the bottom plate is engaged with each other to improve the supporting effect of the placement board. The foam frame provided at the bottom of the box body can avoid direct contact with the bottom of the box body, which causes wear of the bottom of the box body and affects the supporting effect.

[0014] The invention solves the problem that when heavy items are stored in existing cartons and transported, the bottom plate of the carton will be deformed due to the heavy items inside the carton, resulting in insufficient support capacity for the items inside the box, which is very likely to cause the bottom of the packaging carton to break.
