Description

Technical Field

[0001] This utility model relates to the field of corrugated packaging technology, specifically to a full-paper ring cavity buffer liner assembly and its packaging box. Background Technology

[0002] Electronic products use materials such as EPS (polystyrene foam) as packaging cushioning linings mainly because these materials have good cushioning performance and low cost. Therefore, EPS is widely used in the packaging of high-end electronic products, such as laptops and tablets, due to its lightweight, high strength and excellent cushioning performance.

[0003] With increasing global environmental awareness and the establishment of "green trade barriers" by various countries, traditional non-biodegradable materials such as EPS are gradually being replaced by environmentally friendly materials such as corrugated cardboard. As a green packaging material, corrugated cardboard has advantages such as low cost, readily available materials, mature production processes, good processing performance, and easy recycling. Furthermore, corrugated cardboard has a wide operating temperature range, which can meet the packaging needs of various electronic products.

[0004] Because sheet corrugated cardboard has relatively weak cushioning and load-bearing capacity, especially under high-impact conditions, it may not be able to completely replace traditional materials such as EPS. Therefore, a special design using folded corrugated cardboard structures is needed to form a cushioning liner to improve its cushioning and load-bearing effect, thereby better protecting the product. However, the folded structure has a large volume after forming, requiring it to be disassembled into different components for storage and transportation. Furthermore, the formed components cannot be folded and compressed again during storage and transportation, resulting in a large storage and transportation space requirement and a significant increase in storage and transportation costs. In addition, the components must be reassembled during use, leading to low efficiency.

[0005] Therefore, it is necessary to develop a cushioning liner that combines the cushioning performance of a foldable structure with the ability to be folded after molding to reduce storage and transportation space in order to solve this problem. Summary of the Invention

[0006] The purpose of this utility model is to provide a full paper ring cavity cushioning liner assembly and a packaging box with a full paper ring cavity cushioning liner, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0008] A paper-based ring-shaped cushioning liner is provided. The paper-based ring-shaped cushioning liner is integrally folded from a single piece of corrugated cardboard. The formed three-dimensional paper-based ring-shaped cushioning liner can be folded again into a sheet structure. The paper-based ring-shaped cushioning liner includes an inner wall of the ring cavity, an outer wall of the ring cavity, a bottom support, and an elastic cushioning structure sandwiched between the inner wall of the ring cavity and the outer wall of the ring cavity. The inner wall of the ring cavity and the outer wall of the ring cavity are connected by a connecting piece. The elastic cushioning structure and the bottom support are both extended and folded outward from the outer wall of the ring cavity, and both have an M-shaped cushioning structure.

[0009] Furthermore, both the inner wall and the outer wall of the annular cavity include four sequentially connected flaps.

[0010] Furthermore, one side of the inner wall of the annular cavity extends outward from the locking bottom.

[0011] Furthermore, the elastic buffer structure and the M-shaped buffer structure of the base are also provided with a square-shaped buffer structure.

[0012] The present invention also discloses a packaging box with a full paper ring cavity cushioning liner, wherein at least one pair of full paper ring cavity cushioning liners are arranged opposite each other inside the packaging box, and the two ends of the packaged item are respectively fitted and fixed inside the full paper ring cavity cushioning liner.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes an elastic buffer structure composed of an M-shaped buffer structure and a U-shaped buffer structure sandwiched between the inner and outer walls of the ring cavity to form a buffer ring cavity. The packaged product is placed within the space formed by the inner walls of the ring cavity. When the product is impacted, the spring-like M-structure can effectively release the impact force and has resilience, while the U-shaped structure supplements the elasticity of the M-structure, preventing the packaging from being damaged or failing after impact. The finished all-paper ring cavity buffer liner is foldable, facilitating transportation and reducing transportation and storage costs. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-4 As shown, this embodiment discloses a full-paper ring cavity buffer liner. The full-paper ring cavity buffer liner is integrally folded from a single piece of corrugated cardboard. The formed three-dimensional full-paper ring cavity buffer liner can be folded again into a sheet structure. The full-paper ring cavity buffer liner includes an inner ring cavity wall 1, an outer ring cavity wall 2, a bottom support 3, and an elastic buffer structure 4 sandwiched between the inner ring cavity wall 1 and the outer ring cavity wall 2. The inner ring cavity wall 1 and the outer ring cavity wall 2 are connected by a connecting piece 5. The elastic buffer structure 4 and the bottom support 3 are both extended and folded outward from the outer ring cavity wall 2, and both have an M-shaped buffer structure.

[0026] The inner wall 1 of the annular cavity includes four sequentially connected flaps: inner flap 12, inner flap 23, inner flap 34, and inner flap 45. The outer wall 2 of the annular cavity includes four sequentially connected flaps: outer flap 11, outer flap 22, outer flap 33, and outer flap 44. The inner flap 23 of the inner wall 1 and the outer flap 33 of the outer wall 2 are connected by a connecting piece 5.

[0027] One side of the inner wall 1 of the annular cavity extends outward to form a self-locking bottom 11. The self-locking bottom 11 is for providing support for the bottom of the inner wall 1 of the annular cavity after it is bonded and formed, and also provides a certain buffer support for the bottom of the all-paper annular cavity buffer liner.

[0028] The M-shaped buffer structure 41 of the elastic buffer structure 4 is formed by extending and folding the outer flaps 21, 22, 23, and 24 of the outer wall 2 of the annular cavity outward. Each flap of the outer wall 2 of the annular cavity extends outward to form two M-shaped buffer structures 41. The two M-shaped buffer structures 41 are connected by a support piece. The height of the support piece is the same as the height of the outer wall 2 of the annular cavity. In addition to connecting the two M-shaped buffer structures 41, the support piece can also strengthen the support performance of the outer wall 2 of the annular cavity and enhance the load-bearing performance of the entire paper annular cavity buffer liner.

[0029] The base 3 extends outward from the other side of the outer flap 21 of the outer wall of the annular cavity 2 and is folded to form an M-shaped buffer structure 31, which provides a buffering effect for the bottom of the all-paper annular cavity buffer liner.

[0030] Both the M-shaped buffer structure 41 of the elastic buffer structure 4 and the M-shaped buffer structure 31 of the base support 3 are provided with a square-shaped buffer structure 42. The square-shaped buffer structure 42 also has a similar M-shaped buffer structure, providing elastic rebound energy to the M-shaped buffer structure 31 and the M-shaped buffer structure 41, and also providing a certain impact buffer.

[0031] The present invention also discloses a packaging box with a full paper ring cavity cushioning liner. At least one pair of full paper ring cavity cushioning liners are arranged opposite each other inside the packaging box. The two ends of the packaged items are respectively fitted and fixed inside the full paper ring cavity cushioning liners, so that the packaged items are completely protected by the full paper ring cavity cushioning liners.

[0032] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
