Description

Technical Field

[0001] The utility model belongs to the technical field of packaging, and in particular relates to a corrugated paper cushion and a cushioning packaging box. Background Art

[0002] As the world's awareness of environmental protection grows, the application of traditional cushioning materials such as polystyrene foam (EPS) in the field of logistics and transportation is facing severe challenges. EPS materials play an important role in protecting goods from impact damage during transportation with their excellent shock absorption effect, but their disadvantages that cannot be ignored are that they are difficult to degrade in the natural environment, the degradation cycle is as long as hundreds of years, and harmful substances may be released during the degradation process, posing a potential threat to the ecological environment.

[0003] In view of this, seeking an alternative material that is both environmentally friendly and has good cushioning performance has become the focus of the industry. As a widely used packaging material, corrugated cardboard has become an ideal choice to replace plastic cushioning materials such as EPS due to its recyclable and easily degradable environmental characteristics and relatively low cost. However, the traditional corrugated cardboard structure has limitations in providing sufficient cushioning capacity, especially when subjected to complex or high-intensity impacts, the effect is often unsatisfactory.

[0004] Therefore, there is an urgent need for a corrugated paper cushion and cushion packaging box that can effectively alleviate the impact on goods during transportation and conform to the concept of green environmental protection. Utility Model Content

[0012] Further, the outer limiting band is cut from the inside of the corrugated cardboard of the buffer layer.

[0013] Further, an inner limiting opening is formed in the inner bending portion close to the bearing plate. The starting end of the inner limiting band is connected to one end of the buffer layer away from the bearing plate, and the end of the inner limiting band is inserted into the inner limiting opening.

[0014] Further, the inner limiting band is connected to and integrally formed with the end of the corrugated cardboard of the buffer layer.

[0033] Refer to the attached Figure 1 to the attached Figure 7 , which shows a specific embodiment of a corrugated paper cushion and a cushion packaging box provided by the present utility model.

[0034] Refer to the attached Figure 1 , the corrugated paper cushion includes:

[0035] A bearing plate 1, the bearing plate 1 includes a bearing surface 110 and a buffer surface 120;

[0036] Two buffer layers 2 symmetrically arranged at both ends of the buffer surface 120 of the bearing plate 1. The buffer layer 2 is formed by folding corrugated cardboard back and forth multiple times. The buffer layer 2 is formed with a plurality of bending portions 210. A limiting band 220 is connected between the bending portion 210 near the bearing plate 1 and the bending portion 210 far from the bearing plate 1 on the buffer layer 2, for limiting the maximum height of the buffer layer 2.

[0037] Refer to the attached Figure 1 , in the above embodiment, the bearing surface 110 of the bearing plate 1 is used to carry the goods 4, the buffer surface 120 of the bearing plate 1 is used to face the side of the packaging box, the buffer layer 2 is formed by folding corrugated cardboard back and forth multiple times, and its structure is similar to the M shape but the number of folds is not limited. Since the corrugated cardboard folded back and forth is easy to rebound and unfold, in this embodiment, the limiting band 220 is connected from the bending portion 210 near the bearing plate 1 to the bending portion 210 far from the bearing plate 1, limiting the maximum height of the buffer layer 2, avoiding the buffer layer 2 from rebounding and unfolding, and ensuring the stable structure of the cushion.

[0038] Refer to the attached Figure 2 to the attached Figure 4, in the above embodiment, the plurality of bending portions 210 include an outer bending portion 211 and an inner bending portion 212, and the limiting band 220 includes an outer limiting band 221 connected to one end of the outer bending portion 211 and an inner limiting band 222 connected to one end of the inner bending portion 212. In the embodiment, the outer limiting band 221 is used to limit the outer bending portion 211, and the inner limiting band 222 is used to limit the inner bending portion 212, so that the buffer layer 2 does not come apart as a whole.

[0039] Refer to the appendix Figure 4 and the appendix Figure 5 , in the above embodiment, an outer limiting opening 230 is formed in the outer bending portion 211 away from the bearing plate 1. The starting end of the outer limiting band 221 is close to the bearing plate 1, and the end of the outer limiting band 221 is inserted into the outer limiting opening 230. In the embodiment, the end of the outer limiting band 221 is movably arranged, and inserting it into the outer limiting opening 230 realizes the limiting effect on the outer bending portion 211. When not in use, the restriction can be released by pulling out the end of the outer limiting band 221 from the outer limiting opening 230. In the above embodiment, the outer limiting band 221 is cut from the inside of the corrugated cardboard of the buffer layer 2.

[0040] Refer to the appendix Figure 3 and the appendix Figure 5 , in the above embodiment, an inner limiting opening 240 is formed in the inner bending portion 212 close to the bearing plate 1. The starting end of the inner limiting band 222 is connected to one end of the buffer layer 2 away from the bearing plate 1, and the end of the inner limiting band 222 is inserted into the inner limiting opening 240. In the embodiment, the end of the inner limiting band 222 is movably arranged, and inserting it into the inner limiting opening 240 realizes the limiting effect on the inner bending portion 212. Before using it as a buffer pad, both the outer limiting band 221 and the inner limiting band 222 can be taken out from the corresponding limiting openings, so that the buffer layer 2 is in a fully unfolded state, reducing space occupation and facilitating storage. In the above embodiment, the inner limiting band 222 is connected to the end of the corrugated cardboard of the buffer layer 2 and integrally formed.

[0041] Refer to the appendix Figure 5, in the above embodiment, a trapezoidal structure 2221 is provided at the end of the inner limiting band 222, and the width of the end of the trapezoidal structure 2221 is greater than the width of the inner limiting opening 240. In the embodiment, the trapezoidal structure 2221 is configured such that after the inner limiting band 222 is inserted into the inner limiting opening 240, it will not disengage from the inner limiting opening 240 because the width of the end of the trapezoidal structure 2221 is greater than the width of the inner limiting opening 240. Specifically, during installation, the trapezoidal structure 2221 is manually squeezed to deform it and then inserted into the inner limiting opening 240. When the limiting state needs to be released, first untie the outer limiting band 221, and then squeeze and push out the trapezoidal structure 2221 from one side of the outer bending portion 211 to push it out of the inner limiting opening 240. In the above embodiment, two inner limiting openings 240 and two inner limiting bands 222 are provided in the inner bending portion 212.

[0042] See the appendix Figure 5 , in the above embodiment, the buffer layer 2 and the bearing plate 1 are integrally formed structures. In the embodiment, during the production process, only by cutting can an unfolded buffer pad be cut out from a sufficiently large corrugated paper, reducing the splicing steps.
