AI Technical Summary
While existing corrugated cardboard boxes improve stability during transportation by incorporating frames and limiting materials, they also increase production costs and inconvenience in use. Furthermore, damaged tape can easily cause the boxes to open, failing to effectively protect the integrity of the goods.
The carton lid is secured with elastic bands and limit buckles, and a shock-absorbing membrane is installed on the inside of the corrugated cardboard. The shock-absorbing membrane can be inflated, and the cushioning structure of the corrugated cardboard interlayer is a composite square to enhance the compression resistance.
It effectively prevents the carton from opening and the goods from being damaged without increasing the weight of the carton, thus improving stability and shock absorption during transportation.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of corrugated cardboard box technology, specifically relating to a corrugated cardboard box with good shock absorption effect. Background Technology
[0002] Corrugated cardboard boxes are made from corrugated cardboard through processes such as die-cutting, creasing, stapling, or gluing. Corrugated cardboard consists of multiple layers of paper, with a corrugated core, giving the box excellent compression resistance and cushioning properties. Corrugated cardboard boxes are widely used in the packaging and transportation of various goods, including food, beverages, electronics, and daily necessities. They not only protect goods from damage but also facilitate warehousing and transportation.
[0003] To more effectively ensure the integrity of goods during transportation, existing corrugated cardboard boxes improve stability by setting up a frame for support and placing limiting and shock-absorbing materials inside the box. Although the protection is in place, it will cause inconvenience to the storage, stacking and transportation of the cardboard boxes before use, and significantly increase production costs and packaging weight. Utility Model Content
[0004] The purpose of this utility model is to provide a corrugated cardboard box with good shock absorption effect, including a corrugated cardboard body, which is formed into a cuboid by folds. The top and bottom two sets of cover plates of the corrugated cardboard body are provided with elastic bands and limiting buckles. The elastic bands are fixed to one side of each set of cover plates, and the limiting buckles are fixed to the other side of each set of cover plates. It also includes a shock-absorbing membrane, which is disposed inside the corrugated cardboard body.
[0005] Preferably, the edge portion of the shock-absorbing membrane is fixed to the corrugated cardboard body, and the middle portion of the shock-absorbing membrane is an air-filled space.
[0006] Preferably, the damping membrane also has an air inlet.
[0007] Preferably, the corrugated cardboard body has a cushioning structure in its interlayer, and the cushioning structure is a composite square structure.
[0008] Preferably, the middle portion of the shock-absorbing membrane is filled with polyethylene foam particles.
[0009] The beneficial effects of this utility model are:
[0010] The use of elastic bands and locking buckles ensures that even if the tape breaks after the corrugated cardboard box is loaded, the lid will not pop open and the goods will not leak out, thus preventing damage and ensuring the integrity of the goods. The shock-absorbing membrane inside the corrugated cardboard inflates when air is injected during loading, providing excellent shock absorption and preventing damage caused by the goods colliding with the inner wall of the box. By folding the corrugated cardboard layers into a square structure, the compressive strength of the cardboard is maximized, effectively preventing deformation and damage during transportation and improving the stability of the corrugated cardboard box.
[0011] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] like Figures 1 to 3 As shown, this embodiment provides a corrugated cardboard box with good shock absorption, including a corrugated cardboard body 1. The corrugated cardboard body 1 is formed into a cuboid by folds. The top and bottom two sets of flaps of the corrugated cardboard body 1 are each provided with elastic bands 2 and limiting buckles 3. The base of the elastic band 2 is fixed to one side of each set of flaps by hot melt adhesive, and the bottom of the limiting buckle 3 is fixed to the other side of each set of flaps by hot melt adhesive. In normal circumstances, cardboard boxes for express delivery are sealed with tape. In this embodiment, double protection is adopted. After the cardboard box is sealed with tape, the elastic band 2 is pulled up and put on the surface of the corresponding limiting buckle 3, which can generate a pulling force on the top flap and prevent the cardboard box flap from breaking open due to external force and gravity.
[0021] It also includes a shock-absorbing membrane 4, which is disposed inside the corrugated cardboard body 1. In this embodiment, the shock-absorbing membrane 4 is made of a soft heat-sealable plastic film, and the shock-absorbing membranes 4 on each side are interconnected. The edges of the shock-absorbing membrane 4 are sealed and fixed to the corrugated cardboard body 1 by a heat-sealing rod. The middle part of the shock-absorbing membrane 4 is an inflation space. The shock-absorbing membrane 4 also has an inflation port 6. The middle part of the shock-absorbing membrane 4 is filled with polyethylene foam particles 5 to prevent the shock-absorbing membrane 4 from leaking air and drying out during transportation, thus losing its shock-absorbing function. The polyethylene foam particles 5 can still play a stress-relieving role. When the corrugated cardboard body 1 is in the stacked state of the storage box, the shock-absorbing membrane 4 is in a contracted state. When the corrugated cardboard body 1 is put into use, it is only necessary to inflate the inflation port 6 and heat-seal it to make the shock-absorbing membrane 4 bulge out, which can achieve the shock-absorbing effect without increasing the weight of the box itself.
[0022] The corrugated cardboard body 1 has a buffer structure 7 in its interlayer. The buffer structure 7 is a composite square structure, that is, the square has triangular diagonal braces inside, which can transmit the external pressure to both sides of the square and the internal diagonal surface at the same time, thereby increasing the resistance to external pressure, achieving a better buffering effect, and increasing the stability of the buffer structure 7.
[0023] All the devices selected in this application (parts whose specific structures are not specified) are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
