The first buffering bar 21, the second buffering bar 22, and the third buffering bar 23 are preferably made from the same material which can be ethyl vinyl acetate (EVA) or expandable polyethylene (EPE) or other suitable material.

The packaging device can be used to support and protect the panel. Furthermore, the packaging device can be used on protecting and supporting any panels from electronics, such as a liquid crystal display panel, a glass substrate, and a glass substrate for solar energy, and other displaying panels.

FIG. 2 is a depiction of how the packaging device shown in FIG. 1 is used along with a liquid crystal display panel. As shown in FIG. 2, the panel 20 to be packed can be a glass substrate, a liquid crystal display panel, a glass substrate, and a glass substrate for solar energy, and other displaying panels. The packaging device 30, 31, 32 and 33 are identical to the corner guard 10 shown in FIG. 1. Each of the packaging device 30, 31, 32 and 33 is attached to a corresponding corner of the panel 20 and the panel 20 is further supported and protected by the first buffering bar 21, the second buffering bar 22, and the third buffering bar 23. By this arrangement, the panel 20 is properly and reasonably supported and protected.

FIG. 3 is an unfolded view of the packaging device shown in FIG. 1 before it is folded. As shown in FIGS. 1 and 3, the corner guard 10 includes a first central portion 11, a pair of second side portions 12, 13 and a pair of third end portions 14, 15.

The first central portion 11 includes a pair of first longitudinal sides 111, 112 with the second side portions 12, 13 interconnected thereto respectively. The second side portions 12 includes a bottom 121 which is perpendicular to the first longitudinal side 111, and the other second side portion 13 has a bottom 131 which is perpendicular to the longitudinal side 112. The second side portions 12, 13 can be folded up as centered on the central portion 11 and arranged in parallel to each other.

The third end portion 14 are each interconnected to the bottom 121 of the side portion 12, and the other end portion 15 is interconnected to the bottom 131 of the side portion 13. The third end portions 14, 15 can be folded up with respect to the second side portion 12, 13, and then overlapped and glued together.

In the current embodiment, the first central portion 11 and the third end portion 14, 15 are rectangular shaped, while the second side portions 12, 13 have the triangular shape. 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.
