As a transport box used when transferring from a glass maker to a device maker, a box as shown in FIG. 7 has been known.
In FIG. 7, reference numeral 01 denotes a glass substrate transport box, which is composed of a bottomed main body portion 02 having an open upper end and a lid (not shown). In the main body portion 02, both sides or lower sides of a plurality of glass substrates 03 are provided. A pair of insert plates 04 each having a plurality of vertical grooves 04a for supporting (not shown) are inserted. These glass substrates 03 are engaged and supported one by one in the vertical groove 04a of the facing insert plate 04, and the lid is conveyed over the main body 02 so as to press the upper side of the glass substrate 03 from above. However, in recent years, the vertical and horizontal dimensions of the glass substrate have tended to be large, for reasons of increasing the efficiency of transporting the glass substrate, improving the loading efficiency, and reducing the unit price per transported number. Dimensions of 1800 × 2000 × 0.7 have become mainstream.
