By this arrangement, a preset or predetermined number of panels 24 can be properly and securely disposed within the holder 212 with every two adjacent panels 24 is interposed with a buffering pad 23. Once the preset or predetermined number of panels 24 is disposed within the holder 212, the cover lid 211 is covered onto the holder 212. Then the packaging device 20 can be erected and then put onto a carrier or vehicle and transported to next workstation. Once the packaging device 20 is erected or held vertically, the positioning device 22 is located on top portion. Since the buffering pads 23 are engaged with the positioning device 22. all the buffering pads 23 are held vertically therefore providing excellent buffering protection.
[0042] Alternatively, the tab portion 231 can be omitted and the retaining holes 232 can be defined along the side of the buffering pad 231.
[0043] Alternatively, the positioning device 22 can be fixedly attached to a ceiling of the cover lid 211 and extends downward. In assembling, a first buffering pad 23 can be laid down the bottom of the holder 23 firstly, and then a panel 24 is placed onto the first buffering pad 23. Then, a second buffering pad 23 is deployed over the first panel 24, and then a second panel 24 is disposed thereon. With a layer of buffering pad 23, and a layer of panel 24, a preset or predetermined number of panels 24 can be disposed within the holder 212.

Accordingly, the positioning device 22 can be bolted within the threaded recess 2121. The holder 212 can be provided with a plurality of threaded recesses 2121, and they can be arranged on a side of the bottom. Alternatively, opposite sides of the bottom can be arranged with the threaded recesses 2121, or alternatively, totally four sides of the bottom can be defined with threaded recesses 2121. In other alternatively, the positioning device 22 can be arranged in the bottom of the holder 212 based on different buffering pads 23 of different dimensions. As a result, different buffering pads 23 can all be used in a common holder 212. Alternatively, the threaded recess 2121 can also be arranged on the ceiling of the cover lid 211. Since it works and functions in the same way, no further description is given.
[0047] Alternatively, the positioning device 22 can use other arrangement other than threaded engagement between the threaded portion 221 and threaded recess 2121. For example, a projection can he directly formed on the bottom of the holder 212 and then extends therefrom. Alternatively, the projection can also be rooted from the ceiling and extends downward therefrom. The projection can be any geometry, such as circular, rectangular, and other suitable shape.
[0048] In the present invention, the positioning device 22 is disposed on the inner surface the container 21, and the buffering pads 23 and the panels 24 are alternatively disposed in the space defined by the container 21. In addition, the retaining holes 232 of the buffering pads 23 are engaged with the positioning device 22. The buffering pads 23 can be selected from soft material of cost effective. After the cover lid 211 is engaged with the holder 212, the packaging device 20 can be readily carried by an automatic vehicle and other suitable means. Once the packaging device 20 is erected vertically, the buffering pads 23 are also held vertically with the help of the positioning device 22. The buffering pads 23 will not slack down because of its softness. As a result, no matter how the packaging device 20 is arranged, every two adjacent panels 24 are well separated and protected by the buffering pad 23 sandwiched therebetween. Since the buffering pads 23 can be selected from soft material of cost effective, the cost is therefore reduced.
