## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of packaging material, and in particular to a package box of liquid crystal glass.
2. The Related Arts
In the field of manufacture of liquid crystal display devices, the manufacture of liquid crystal display devices includes a process of assembling, which assembles various components, including a liquid crystal glass, a main control circuit, and an enclosure, together. These components are each manufactured in advance and packaged for being later assembled to form a complete liquid crystal display device. The liquid crystal glass, after being manufactured, is packaged in a liquid crystal glass package box and then shipped in box to a corresponding assembling station. Commonly used package boxes include paper boxes and plastic cases. Paper boxes have better cushioning property but are of poor stiffness for serving as liquid crystal glass package boxes. Plastic cases have better structures so as to not easily have objected contained therein damaged by applications of external forces and are of low prices so as to be fit to packaging of fragile articles. However, plastic cases show poor cushioning performance so that cushioning blocks must be additionally provided inside the cases to effect cushioning.
As shown in FIGS. 1 and 2, which are schematic views showing a conventional liquid crystal glass package box, the conventional liquid crystal glass package box comprises a box body 100, mounting sections 300 arranged inside the box body 100, and cushioning blocks 500 that are mounted on the mounting sections 300 and are arranged to engage a piece of liquid crystal glass. These cushioning blocks 500 are adhesively bonded to the mounting sections 300. A packaged piece of liquid crystal glass is so set that edges thereof are positioned on the cushioning blocks 500. In shipping the liquid crystal glass, the cushioning blocks 500 provide an effective protection to the liquid crystal glass and prevent the liquid crystal glass from being damaged by external forces. Commonly used cushioning blocks 500 are often made of foaming substances, such as expandable polyethylene (EPE) and ethylene-vinyl acetate (EVA) copolymer. The package boxes, after being used, can be collected and for re-use. However, during the process of use, the cushioning blocks 500 may get damaged and must be removed and re-worked. However, since the cushioning blocks 500 are adhesively bonded to the mounting sections 300, re-working easily suffers residues of adhesive. This increases the difficulty of removing and re-working thereby lowering the efficiency of re-working.

The mounting sections 4 each comprise a first receiving channel 404 and a through hole 408 respectively corresponding to the retention section 64 and the projection 68 of the respective cushioning device 6. To assemble, the retention sections 64 are respectively received in the first receiving channels 404 and the projections 68 are respectively fit into the through hole 408 to fix the cushioning devices 6 inside the box body 2. When a piece of liquid crystal glass 8 is packed in the box body 2, edges of the liquid crystal glass 8 are positioned on the cushioning sections 62. During shipping, the liquid crystal glass 8 may compress the cushioning sections 62 and the cushioning sections 62 that are made of a foamed material provide a cushioning effect to protect the liquid crystal glass 8 against damage.
The box body 2 may comprise a top cover (not shown) and a bottom case 22 mating the top cover. The mounting sections 4 are fixed inside the bottom case 22. The bottom case 22 comprises a bottom board 222 and side boards 224 perpendicularly connected to the bottom board 222. The mounting sections 4 are mounted to the bottom board 222. Preferably, the mounting sections 4 are arranged at locations corresponding to opposite ends of each of the side boards 224.
The bottom case 22 and the plurality of mounting sections 4 are integrally formed. Each of the mounting sections 4 comprises first and second mounting plates 42, 44 that are parallel to each other and first and second reinforcing plates 46, 48 that are connected to the first and second mounting plates 42, 44. The first and second reinforcing plates 46, 48 are both perpendicularly connected to the respective side board 224. The first and second mounting plates 42, 44 are parallel to the side board 224 to which the first and second reinforcing plates 46, 48 are connected. The second mounting plate 44 is arranged between the first mounting plate 42 and the side board 224. The first and second mounting plates 42, 44 form therebetween the first receiving channel 404. The second mounting plate 44 and the side board 224 form therebetween a second receiving channel 406. The through hole 408 is formed in the second mounting plate 44.
