That is to say, the packaging structure 300 of the present embodiment can hold the article 301 together by the abutting portion 344 of the intermediate buffer body 340 against the bump 330, thereby enhancing the protection of the packaging structure 300 against the article 301.

In the foregoing embodiment, the abutting projections 330 are integrally formed with the buffer rod 320, for example, and the number thereof may be determined according to actual needs. However, in other embodiments, the abutting bumps 330 and the bumper rods 320 may be made of different materials and assembled to each other. As shown in FIG. 9, the bumper bar 420 can have the same number of mating holes 422 as the abutment tabs 430 to facilitate partial engagement of the abutment tabs 430 therein. Alternatively, as shown in FIG. 10 , the abutting protrusion 530 has a through hole 532 , and the buffer rod 520 is disposed through the through hole 532 . In the embodiment shown in FIG. 9 and FIG. 10, the buffer rod 420 and the buffer rod 520 can be made of cardboard, and the material against the protrusion 430 and the abutting protrusion 530 is, for example, foamed polyethylene.

As can be seen from the above, the abutting lugs attached to the bumper bar can provide protection against damage that is easily damaged when the article to be packaged is dropped. In the case of a flat panel display, in the drop test, if the drop height is 61 cm, the flat panel display covered with the package structure of the present invention is received at the position corresponding to the bump (the lower edge of the flat display) The impact force is 149.88G, where G is the acceleration of gravity. In contrast to the conventional four-piece packaging structure 100 of Figure 1, the impact force experienced by the abutment bumps is substantially reduced by about 200G.

In summary, the packaging structure of the present invention is designed with a buffer rod between the two corner buffers, and abutting bumps are connected to the buffer rods, which can be Provides more complete protection when items are dropped to reduce the chance of damage during shipment. Moreover, since the buffer rod is detachably assembled between the two corner cushion bodies, not only the inventory space of the packaging structure can be reduced, but also the mold opening cost of the packaging structure can be reduced.

In addition, in the package structure of the present invention, the corner cushion body and the buffer rod are assembled to each other, and the engaging surface may be a sloped surface to increase the engagement area, thereby improving the engaging force. Moreover, designing the engaging surface as a bevel can also avoid the problem of the right angle accumulation of the corner cushion body and the buffer rod during assembly, thereby improving the cleanliness of the packaging line. In addition, the draft angle of the corner buffer or the buffer rod during the manufacturing process can be increased to prevent the snap block from being broken due to insufficient structural thickness.

While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
