[Previous technology] Electronic products such as notebook computers are in the process of being transported. Because it is easily damaged by external impacts, the packaging structure is more demanding. At present, the more common practice is to provide multiple buffer devices in the package, such as separators, paper or plastic linings, plastic-filled foams, and foam cushions, to avoid sloshing during the delivery of electronic products. It hits the wall of the package and protects the electronics inside the package. However, such cushioning devices often have uneven edges, so it is easy to cut and use I. Moreover, plastic buffers will have an adverse effect on the ecological environment. In contrast, paper buffers not only reduce the impact on the ecological environment, but also reduce the space required for warehouse health, and have a competitive advantage in cost. At present, the more commonly used paper buffering device is made by directly molding the paper m by means of a mold. Alternatively, the paperboard may be cut into various shapes according to the design requirements, and then formed by folding and pasting. Conventional packaging boxes often contain different types of structurally asymmetric buffering devices, increasing the cost of production assembly, transportation, and material handling of the cushioning device. Therefore, how to provide a cushioning device which can be folded by using a paper material and has a flat shape and a symmetrical structure is a user [invention] 200827257 The purpose of the present invention is to provide a packaging box and The cushioning device, wherein the cushioning device can support and fix the articles in the package to prevent the damage of the article caused by the impact force of the outside.

In order for the cushioning device 300 to provide a better cushioning effect, the first flat plate 342 has a buffer opening 363 disposed thereon. The buffer opening 363 is, for example, a long strip opening, and the length of the buffer opening u 363 may be about two thirds of the length of the buffer device 300. Figure 4 is a schematic view of a sheet material of a cushioning device in accordance with a preferred embodiment of the present invention. Referring to Figure 4, the material of the sheet 5 is preferably selected from paper materials such as corrugated paper, coated paper, etc., and the wave direction of the material (for example, corrugated paper) is taken as "axial pressure". It can enhance the structure and assist the carton to withstand the pressure resistance of the stack. The plate 5 can be directly pressed or formed by the mold using a mold or cut with a single-board. Before the sheet is folded, it is - The flat paperboard can form a buffer device after the folding process. The plate 5 includes a bottom plate 31, two long side plates 320, two short side plates 330, and two receiving structures 341a, (4). In detail, the bottom plate 310 has a rectangular shape, for example, and the long side 311 of the bottom plate 31 is sequentially connected to the long side plate 320, the first flat plate 342, the second flat plate 344, and the third flat plate 349. The long side plate 320 and the bottom plate 310 have A first fold line 351 ′ between the first flat plate 342 and the long side plate 320 has a second fold line 352 ′. The second flat plate 344 and the first flat plate 342 have a third fold line 353 , and the second flat plate 349 and the second flat plate Between 344 has a fourth A fold line 354. A slit 361 and a slit 362 which are parallel to each other are formed on the first flat plate 342 and the second flat plate 344. Above the first flat plate 342, a slit line 361 and a slit f slit 362 have a fifth fold line. 355, on the second plate 344, a slit line 361 and a quilt 362 have a sixth fold line 3 56 and a seventh fold line 357. The first fold line 351, the second fold line 352, the third fold line 353, the first The four fold line 354, the fifth fold line 355, the sixth fold line 356, and the seventh fold line 357 are parallel to each other, and the slit 361 is perpendicular to the first fold line 351. The fifth fold line 355, the sixth fold line 356, the seventh fold line 357, and the slit 361 And the slit 362 defines a concave side plate 346 and a concave bottom plate 348. Continuing to refer to Fig. 4, the short side plate 33 is connected to the short side of the bottom plate 31, and the edge 312 has an eighth fold line 358 between the short side plate 330 and the bottom plate 310. The short side panel 330 has at least one first fixing piece 332 connected to the short side side plate 330, and a first ninth folding line 359 between the first fixing piece 332 and the short side side plate 33. The short side side plate 330 has two second fixing pieces. 334, connected to the short side side plate 330. The second fixing piece 334 and the short side side plate 330 have a The tenth fold line 360 〇 refers to FIG. 2, FIG. 3 and FIG. 4 at the same time, and the sheet material 500 can be folded by the following steps to form a cushioning device.
