Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, specifically a corrugated cardboard box with cushioning function. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. Due to their superior performance and ease of processing, corrugated boxes have gradually replaced wooden crates and other transport packaging containers, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are also considered environmentally friendly products, benefiting both the environment and the loading and unloading process.

[0003] A composite corrugated cardboard box, with application number 202322943770.7, includes a corrugated cardboard box body. A plastic pad is placed on the bottom of the corrugated cardboard box body, a cushioning layer is placed on top of the plastic pad, and a plastic cover is placed on top of the cushioning layer. The cushioning layer, located within a composite bottom plate, reduces the impact of bumps on the contents of the corrugated cardboard box during transportation. The cushioning layer is placed on the plastic pad and then sealed by the plastic cover, which is convenient. However, the corrugated cardboard box has low compression and impact resistance, and its cushioning effect on the inner sidewalls of the box is poor. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated cardboard box with a cushioning function to solve the problems of low compression and collision resistance of existing corrugated cardboard boxes and poor cushioning effect on the inner sidewalls of corrugated cardboard boxes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard box with a cushioning function, comprising a corrugated cardboard box body, a folded cover on the upper part of the corrugated cardboard box body, a first reinforcing rib on the inner wall of the corrugated cardboard box body, a first cushioning hole inside the first reinforcing rib, and a first cushioning block inserted into the first cushioning hole, a cushioning bottom plate snapped into the inner bottom of the corrugated cardboard box body, a second reinforcing rib on the lower side of the cushioning bottom plate, a second cushioning hole inside the second reinforcing rib, and a second cushioning block inserted into the second cushioning hole.

[0006] Furthermore, both the first and second reinforcing ribs are configured as hollow semi-cylindrical shapes, and the thickness of the first and second reinforcing ribs is twice the thickness of the side wall of the corrugated cardboard box.

[0007] Furthermore, a reinforcing plate is provided between the first reinforcing rib and the corrugated cardboard box body, and the reinforcing plate is a trapezoidal plate.

[0008] Furthermore, the reinforcing plate is provided with multiple plates at equal intervals, and a third buffer hole is provided inside the reinforcing plate.

[0009] Furthermore, the inner wall of the second buffer hole of the second reinforcing rib is also provided with a third reinforcing rib, and the second buffer block is provided with a fourth buffer hole.

[0010] Furthermore, the outer side of the buffer base plate is provided with a limiting groove, and the limiting groove is slidably disposed with the lower end outer wall of the first reinforcing rib.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features a first reinforcing rib on the inner wall of the corrugated cardboard box and a second reinforcing rib on the lower side of the buffer bottom plate, which increases the structural strength of the corrugated cardboard box and improves its resistance to pressure and impact. Furthermore, the first buffer hole and the first buffer block inside the first reinforcing rib can buffer the inner wall of the corrugated cardboard box, while the second buffer hole and the second buffer block inside the second reinforcing rib on the lower side of the buffer bottom plate can buffer the bottom of the cardboard box, resulting in a good buffering effect.

[0013] 2. This utility model provides a reinforcing plate between the first reinforcing rib and the corrugated cardboard box body. The reinforcing plate is trapezoidal and has multiple plates spaced at equal intervals. The reinforcing plate also has a third buffer hole inside, which increases the stability of the connection and fixation between the first reinforcing rib and the corrugated cardboard box body, and facilitates the improvement of the structural strength and buffering effect of the first reinforcing rib.

[0014] 3. The present invention provides a third reinforcing rib on the inner wall of the second buffer hole of the second reinforcing rib, which increases the internal structural strength of the second reinforcing rib. The second buffer block is provided with a fourth buffer hole, which reduces the weight of the second buffer block and improves the buffering effect of the second buffer block.
