  On the bottom plate 4 in the box body 2 configured as described above, as shown in FIG. 3, there is a bottom pad 44 for supporting a glass substrate of a rectangular parallelepiped having a predetermined thickness made of, for example, a polypropylene-based foam as a hard material. They are attached in parallel in the longitudinal direction at predetermined intervals (four in the embodiment). On the upper surface of the bottom surface pad 44, ribs 42 having a mountain-shaped cross section, for example, configured to form parallel grooves with a pitch interval of 14 mm are formed.

  A side pad 48 separated vertically is attached to the inner surfaces of the opposing side plates 8a, 8b on the short side of the box body 2, and the side pad 48 is composed of a base member 48a and the base member 48a. For example, a guide rib member 48b having a mountain-shaped cross section that forms parallel vertical flutes with a pitch interval of 14 mm, for example.

  When attaching the side pads 48 separated vertically, the vertical grooves formed by the guide rib members 48b on the base member 48a and the parallel grooves formed by the ribs 42 of the bottom surface pads 44 are set so as to be accurately aligned. Has been.

  Specifically, as shown in FIGS. 5A and 5B, on the lower surface of the base member 48a, a thin resin plate or an aluminum thin plate made of a material having good peelability with respect to the aluminum side plates 8a and 8b. The base plate 48a is attached to the opposing surfaces of the aluminum side plates 8a and 8b by applying an adhesive or an adhesive to the adhesive plate 60. It has become so.

  In particular, the side pad 48 adhered to the upper part is damaged because it becomes damaged due to contact with the corners when the glass substrate G is put in and out, and the function as a guide deteriorates and cannot be used for long-term use. Although it has a possible configuration, the side pad 48 attached to the lower part may be replaced, so it is preferable that the side pad 48 is attached in a replaceable manner.

  Therefore, when the base member 48a is peeled off, it is easier to peel off the sticking plate 60 made of a thin resin plate or aluminum thin plate than the case where the base member 48a is directly bonded. You can leave a face.

  A pair of positioning holes 64 are formed on both the left and right sides of the base member 48a, and a pair of positioning pins 62a and 62b are formed on the side plates 8a and 8b facing each other at positions corresponding to the left and right positioning holes 64 of the base member 48a. It is protruding.

  As shown in FIGS. 4A and 4B, the lower ends of the plurality of glass substrates G are supported on the bottoms of the parallel grooves formed by the ribs 42 of the bottom surface pads 44. Is supported in a state where a slight gap S is formed without touching the groove bottom of the side pad 48.

  These longitudinal grooves formed by the guide rib member 48b support the glass substrate G in parallel, and guide the glass substrate G to be accommodated in or removed from the parallel grooves formed between the ribs 42 of the bottom surface pad 44. Function as.

  The guide rib member 48b has a tapered surface tapered from the top surface to the groove bottom so that the cross-sectional shape thereof is substantially C-shaped, and the guide rib member 48b is also near the opening of the box body 2. A mountain-shaped taper surface is formed so that the height on the side gradually decreases toward the opening end.

  Therefore, according to the side pad 48 of the glass substrate transport box configured as described above, as shown in FIG. 5, the transport box 1 is used for a long time to separate the side pad 48 up and down. When the base member 48a is damaged, the base member 48a attached to the opposing surfaces of the side plates 8a and 8b is peeled off from the attaching plate 60, and the base member 48a is replaced. As in the prior art, the trouble of replacing the entire base member is reduced, and the material can be saved.

  In addition, by using the sticking plate 60, the flat adhesive surface can be regenerated without leaving a broken piece of foamed material on the adhesive surface of the opposing side plates 8a and 8b after peeling. Therefore, the opposite side plates 8a and 8b can be used as the bonding surface of the new base member 48a.

  Further, when a new base member 48a is attached to the bonding surfaces of the opposing side plates 8a and 8b, a pair of positioning pins 62a and 62b projecting from the left and right sides of the side plates 8a and 8b, for example, the upper base member By fitting the left and right positioning holes 64 with 48a, anyone can accurately align the vertical groove 46a of the base member 48a with the vertical groove formed in the lower base member 48a.

  Although the example in which the positioning pins 62a and 62b and the positioning hole 64 are used as the means for positioning the side surface pad 48 has been described, for example, a stepped portion for regulating the lateral direction is provided on the bonding surface of the side plates 8a and 8b. However, the present invention is not limited to the examples.

  When the glass substrate G is inserted, the guide rib member 48b having a substantially C-shaped cross section is guided from the top surface to the groove bottom by a tapered surface and a mountain-shaped opening end, so that the glass substrate at the time of insertion There is room for accurate positioning of G. Further, since the thickness of the base member 48a gradually decreases toward the opening end, the base member 48a is centered with respect to the deviation in the width direction of the glass substrate G when inserted near the opening end.

  Next, both side edges of the glass substrate G are inserted into all the longitudinal grooves of the side surface pad 48, and the lower ends thereof are supported by the groove bottoms of the corresponding parallel grooves of the bottom surface pad 44. When closed by the body 3, as shown in FIG. 4B, the upper and lower ends of the plurality of glass substrates G accommodated in the transport box 1 are the glass substrate contact pads 58 on the back surface of the lid 3. It is pressed simultaneously between the pressing surface 58a and the bottom surface pad 44.

  In this way, by applying a load in the vertical axis direction toward the upper and lower ends of the glass substrate G, the glass between the side pads 48 separated vertically as shown in FIGS. 4 (a) and 4 (b). A forced deflection that curves in either the left or right direction orthogonal to the surface of the substrate G is formed.

  In this state, when the transport box 1 is inverted 90 degrees and the glass substrate G is supported in the horizontal direction, even when a load (self-weight) directed downward in the vertical direction perpendicular to the surface of the glass substrate G is applied. Since the upward forced deflection is maintained, the glass substrate G cannot be bent even if it is bent downward due to its own weight, so that contact with the adjacent glass substrate G can be avoided.

  And since the box main body 2 and the cover body 3 have a structure in which a foamed styrene resin (for example, a foamed polyethylene resin) is sandwiched between aluminum composite plates from both sides, the transport box 1 can be configured to be lightweight, and the force acting from the outside. Can alleviate the impact.

  Further, since the box body 2 is reinforced with the bottom frames 10 and 12 and the frame pillars 20 or the upper frames 22 and 24 made of aluminum or the like, a robust box can be provided, and contact with other articles or long-term storage. The box will not be deformed.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and a point or line display unit may be used as a means for positioning the side surface pads. In addition, although the side pads are described as two on the upper and lower sides, they may be configured with three. Furthermore, the upper and lower frame bodies and the frame pillars constituting the frame body are not limited to those made of aluminum, but may be any material that is lightweight and hard, such as stainless steel.
