Typically, the glass substrate 10 for notebooks and PCs is commercially available in 10.4 ", 11.3", 12.1 ", 13.3", 14.1 ", 15.0", 15.7 ", and the like for TFT-LCD monitors: 15.1", 18.1 ", 20.1 "and 23.0" are commercially available, and LCD TVs are commercially available in various sizes ranging from 10 "to 40". Glass substrates of various sizes are gradually used in accordance with the trend of larger LCDs. According to the present invention, when storing the glass substrate 10, which is rather small, it is possible to stack the auxiliary plate of a simple form on one side and the like, and thus it is also expected to be useful for storing multiple varieties in one box.

In FIG. 7A, only the main body 120 is mainly described, whereas FIG. 7B illustrates a laminated structure of the main body 120. That is, the cover 130 may be covered on the main body 120, and the main body 120 and the cover 130 may be further stacked on the main body 120 in a multilayer form. However, as shown in FIG. 7B, the main body 120 and the cover 130 may be sequentially stacked, but after the main body 120 is nested several times, only one cover 130 may be finally covered. In this case, since the bottom portion of the main body 120 is in the form of unevenness, a separate protective paper may be added. 4 to 7, the main body 120 and the cover 130 have been described under the assumption that the soft parts 20b and 30b are not included, but the main body 120 described with reference to FIGS. 4 to 7 is illustrated. ) And the cover 130 may also be configured in the soft portion (20b, 30b).

It is a perspective view which shows the state which used the support piece for the box of FIG.

A support piece 150 is further provided in the outer groove 124 of the main body 120 and the outer groove 134 of the cover 130. The support piece 150 is formed in a L shape using a hard synthetic resin, and inserted into each of the outer grooves 124 and 134 as 150 '. The insertion method may alternatively be press fitting, adhesion, or heat fusion. Using the support piece 150 can increase the binding force of the band and at the same time prevent damage to the box due to the binding of the band.

Currently, glass substrates with a thickness of 0.7 mm (0.7 t) are used for large LCD TVs, and glass substrates of 0.5-0.6 mm are used for notebooks. As the competition for slimming of laptops and mobile phones is intensifying, the slimming competition of LCD glass substrates mounted therein is also accelerating. Based on the current glass substrate, the box of the present invention accommodates about 5-30 sheets, preferably about 20 sheets on average. The support piece 150 of the present invention is advantageously used when storing 20 or more glass substrates 10 or when the thickness of the glass substrate 10 becomes slim.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.

According to the above configuration and action, the glass substrate storage box of the present invention can be stacked densely while being optimally protected according to the storage quantity of the glass substrate, thereby increasing the storage efficiency.
