Of course, they should not be limited to such shapes as those shapes can be readily modified according to the field requirements.
FIG. 4 illustrates the corresponding positions of the buffering bars arranged over the corner guard of FIG. 3. As shown, there are the first buffering bar 21, the second buffering bar 22, and the third buffering bar 23, and each of the first buffering bar 21, the second buffering bar 22, and the third buffering bar 23 is attached or glued to corresponding portions of the corner guard 10. Substantially, the first buffering bar 21 is attached to the first central portion 11; the second buffering bar 22 is attached to the end portion 14 of the corner guard 10 so as to support one of the two corresponding end surfaces of the panel 20. The third buffering bar 23 is attached to the second side portion 13 and creates a gap with respect to the second side portion 12 such that the corner of the panel 20 can be inserted into that gap. The third buffering bar 23 is served to support the front or back surface of the panel 20.
Referring to FIG. 5 which is a partial enlarged view showing encircled portion of A in FIG. 2. As shown in FIG. 5, the panel 20 to be packed is provided with projection 201 on its frontal or back surface, and a buffering pad 202 is attached onto the projection 201. The buffering pad 202 can be glued onto the top of the projection 201 or with other suitable measurements. By this arrangement, the panel 20 can be prevented from damaging resulted from transversal movement of the projection 201 from adjacent panel 20.
In the preferred embodiment of the present invention, the projection 201 and the third buffering bar 23 are located at the same surface of the panel 20. In addition, the overall height of the projection 201 and the buffering pad 202 is smaller than or equal to the height of the third buffering bar 23 and the thickness of the second side portion 13 of the corner guard 10. By this arrangement, the panel 20 can be effectively supported and protected. Furthermore, the overall thickness can also be reduced.
The buffering pad 201, the first buffering bar 21, the second buffering bar 22, and the third buffering bar 23 are made from same material, such as ethyl vinyl acetate (EVA) or expandable polyethylene (EPE).
In conclusion, the packaging device effectively embodies as a corner protecting device which can effectively provide buffering result to the panel, while with the minimum packaging material used. With a great deal of packaging material saved, the overall cost is effectively reduced.
