Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the sizes of the glass substrates stored in the substrate packaging box may differ not only in height but also in width, there are a large number of types of substrate packaging boxes prepared according to the height and width of the glass substrates. When using various types of substrate packaging boxes, it is necessary to individually calculate the transport volume of glass substrates of each size that varies over time and ensure the maximum required number of substrate packaging boxes for each size. Substrate packaging boxes that are not used for each size have been constantly generated. Due to the increase in the size of the glass substrates, the storage space for the unused substrate packaging boxes has hindered the efficient use of space at the production site.

Modes for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described. The present invention is not limited to the content described in the following embodiments, and design changes can be appropriately made within the scope that satisfies the configuration of the present invention. In the following description, the same parts or parts having the same functions are commonly and appropriately used with the same reference numerals among different drawings, and the repeated description thereof will be omitted as appropriate. Each aspect of the present invention may be appropriately combined within the scope not departing from the gist of the present invention.

[0016] (Embodiment 1) The substrate packaging box of Embodiment 1 will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view schematically showing the substrate packaging box of Embodiment 1. FIG. 2 is a schematic view of the substrate packaging box of Embodiment 1 with the lid removed as viewed from the direction (A) shown in FIG. 1. FIG. 3 is a schematic cross-sectional view of the substrate packaging box of Embodiment 1 cut at the height of (B) shown in FIG. 1.

[0017] As shown in FIG. 1, the substrate packaging box of Embodiment 1 (hereinafter also simply referred to as "box") is composed of a lid 30, an upper body 10, and a lower body 20. With the lid 30, the upper body 10, and the lower body 20 combined, a substrate is stored in the box. The lid 30 is detachable, and by removing the lid 30, the substrate can be taken in and out of the box. The type of the substrate to be stored is not particularly limited, but a glass substrate is preferable, and examples thereof include glass substrates for displays such as liquid crystal panels. The materials of the lid 30, the upper body 10, and the lower body 20 constituting the substrate packaging box are not particularly limited, and resins such as ABS resin and polyvinyl chloride can be used. In the substrate packaging box of Embodiment 1, the upper body 10 and the lower body 20 are detachable, and by replacing the upper body 10, substrates of different sizes can be stored.

[0018] The lid 30 is a substantially plate-shaped member provided with a fitting portion with the upper body 10 at the outer edge on the upper body 10 side, and has a third groove for holding the end of the substrate on the inner surface on the upper body 10 side. By providing the third groove, the substrates can be stored with a space therebetween, so that it is easy to prevent the substrate from being damaged. The third groove of the lid 30 is disposed at a position facing the second groove 24 provided on the bottom surface 21 of the lower body 20. Since the lid 30 and the lower body 20 are commonly used regardless of the size of the substrate, the lid 30, the second groove 24, and the third groove are sized according to the maximum size of the substrate assumed to be stored. The widths of the second groove 24 and the third groove may correspond to the thickness of one substrate, or may correspond to the thickness of a dozen to several dozen substrates.

[0019] The upper body 10 is a cylindrical or annular member having a substantially rectangular opening. The upper body 10 has side wall portions forming four side surfaces, and the upper and lower portions are openings, and does not have upper and lower surfaces. A fitting portion with the lid 30 is provided at the outer edge of the upper body 10 on the lid 30 side, and a fitting portion with the lower body 20 is provided at the outer edge of the upper body 10 on the lower body 20 side. Further, the upper body 10 is provided with a first groove for holding the end of the substrate and a substrate size adjusting spacer 12 on two opposite surfaces out of the four surfaces constituting the inner side (inner surface of the side surface) of the side wall portion of the upper body 10. The first groove and the substrate size adjusting spacer 12 extend from the inner side of the side wall portion of the upper body 10 to the inner side of the side wall portion of the lower body 20. The upper ends of the first groove and the substrate size adjusting spacer 12 are located near the end of the side wall portion on the lid 30 side. The lower ends of the first groove and the substrate size adjusting spacer 12 are located below the joint portion between the upper body 10 and the lower body 20 and are disposed inside the side wall portion of the lower body 20.

[0020] The first groove for holding the end of the substrate is a recess formed between groove side walls 14 protruding from the inner surface of the side surface of the upper body 10. The first groove can hold the end in the width direction of the substrate. The first grooves are arranged in a plurality of rows parallel to each other.

[0021] The spacer 12 for substrate size adjustment is a member that adjusts the distance between the bottom surfaces of two opposing grooves for holding substrates so as to correspond to the size of the substrate to be stored in the width direction. Note that the height of the upper part 10 of the main body corresponds to and is adjusted according to the size of the substrate to be stored in the height direction. As a result, the length of the groove for holding the substrate and the length of the spacer 12 for substrate size adjustment in the height direction correspond to the size of the substrate to be stored in the height direction. The substrate packing box of the present embodiment can accommodate various types of substrates with different sizes in the width direction and the height direction by replacing the upper part 10 of the main body provided with grooves for holding substrates and the spacer 12 for substrate size adjustment provided in specific sizes.

[0022] The lower part 20 of the main body is a container-shaped member having a substantially rectangular opening at the upper part. The lower part 20 of the main body has side wall parts forming four side surfaces and a bottom part forming a bottom surface, with the upper part being an opening and having no upper surface. As described above, the upper surface (bottom surface) 21 of the bottom part of the lower part 20 of the main body has a second groove 24 for holding the end of the substrate, and the second groove 24 is arranged at a position facing a third groove arranged on the inner surface of the lid 30. The second groove 24 of the lower part 20 of the main body is a recess formed between groove side walls 22 protruding from the bottom surface 21. Although no groove for holding the substrate is provided on the inner surface of the side wall part of the lower part 20 of the main body, it may be provided. Further, a handle 26 may be provided on the outer surface of the side wall part of the lower part 20 of the main body. The side surface on which the handle 26 is provided is not particularly limited, and it may be provided on only one side surface, two side surfaces, three side surfaces, or four side surfaces, but it is preferably provided on two opposing side surfaces in terms of ease of handling.

[0023] When the distance from the upper surface (bottom surface) 21 of the bottom part to the joint part (fitting part) with the upper part 10 of the main body in the lower part 20 of the main body is defined as the "height of the lower part 20 of the main body", and the distance from the joint part (fitting part) with the lower part 20 of the main body in the upper part 10 of the main body to the upper end of the side wall part is defined as the "height of the upper part 10 of the main body", it is preferable that the height of the lower part 20 of the main body is equal to or greater than the height of the upper part 10 of the main body. That is, it is preferable that the height of the lower part 20 of the main body is the same as the height of the upper part 10 of the main body or greater than the height of the upper part 10 of the main body. According to such a configuration, the ratio of the part corresponding to the general-purpose product (the lower part 20 of the main body) in the entire substrate packaging box can be increased.

[0024] According to the present embodiment, by adjusting the dimensions of the upper part 10 of the main body, the first groove for holding the end part of the substrate, and the substrate size adjustment spacer 12 according to the size of the substrate, for various types of substrates with different sizes, while the lid 30 and the lower part 20 of the main body can be commonly used, a substrate packaging box corresponding to the storage of various types of substrates can be provided. That is, by configuring the substrate packaging box with a part that can be diverted for substrates of any size (the lower part 20 of the main body and the lid 30) and a part that changes the position of the groove for holding the substrate according to the size of the substrate (the upper part 10 of the main body provided with the first groove and the substrate size adjustment spacer 12), the volume of the constituent members of the substrate packaging box required for storing various types of substrates can be reduced, and the storage space for the substrate packaging box can be reduced.

[0025] (Embodiment 2) The substrate packaging box of Embodiment 2 is different from Embodiment 1 in that an attachment 111 provided with a groove for holding a substrate (first groove) provided in a specific size and a substrate size adjustment spacer 112 is attached to the upper part 110 of the main body of the substrate packaging box, instead of using the upper part 10 of the main body provided with a groove for holding a substrate (first groove) provided in a specific size and a substrate size adjustment spacer 12.

[0026] The substrate packaging box of Embodiment 2 will be described with reference to FIGS. 4 to 6. Regarding the matters common to Embodiment 1, the description will be partially omitted. FIG. 4 is a perspective view schematically showing the substrate packaging box of Embodiment 2. FIG. 5 is a schematic view of the substrate packaging box of Embodiment 2 with the lid removed, as viewed from the direction (A) shown in FIG. 4. FIG. 6 is a schematic cross-sectional view of the substrate packaging box of Embodiment 2 when cut at the height (B) shown in FIG. 4.

[0027] As shown in FIG. 4, the substrate packaging box of Embodiment 2 (hereinafter, also simply referred to as "box") is composed of a lid 30, an upper body 110, an attachment 111, and a lower body 120. The attachment 111 is attached to the upper body 110, and with the lid 30, the upper body 110, and the lower body 120 combined, a substrate is stored in the box. The lid 30 is detachable, and the substrate can be taken in and out of the box with the lid 30 removed. In the substrate packaging box of Embodiment 2, the attachment 111 is detachably provided on the inner surface side of the side wall portion of the upper body 110 and the inner surface side of the side wall portion of the lower body 120. By replacing the attachment 111, substrates of different sizes can be stored.

[0028] The lid 30 is a substantially plate-shaped member provided with a fitting portion with the upper body 110 at the outer edge on the upper body 110 side, and has a groove for holding the substrate on the inner surface on the upper body 110 side. By providing the groove, the substrates can be stored with a space therebetween, so it is easy to prevent damage to the substrates. The groove of the lid 30 is arranged at a position opposite to a second groove 24 provided on the bottom surface 21 of the lower body 120. Since the lid 30 and the lower body 120 are commonly used regardless of the size of the substrate, the lid 30 and the groove are sized according to the maximum size of the substrate assumed to be stored. The width of the groove may correspond to the thickness of one substrate, or may correspond to the thickness of a dozen to several dozen substrates.

[0029] The upper part 110 of the main body is a cylindrical member having a substantially rectangular opening, and has side wall portions forming four side surfaces, and does not have an upper surface and a lower surface. A fitting portion with the lid body 30 is provided at the outer edge of the upper part 110 of the main body on the lid body 30 side, and a fitting portion with the lower part 120 of the main body is provided at the outer edge on the lower part 120 side of the main body. Further, the upper part 110 of the main body has a structure for fixing the attachment 111 on two opposite surfaces out of the four surfaces constituting the inner side (inner surface of the side surface) of the side wall portion of the upper part 110 of the main body. The structure for fixing the attachment 111 is not particularly limited, and examples thereof include a groove that can be fitted with a convex portion of the attachment 111.

[0030] The attachment 111 is provided with a first groove for holding the end portion of the substrate and a substrate size adjusting spacer 112. Further, it has a structure for attaching to the upper part 110 and the lower part 120 of the main body. The structure for attaching to the upper part 110 and the lower part 120 of the main body is not particularly limited, and examples thereof include a convex portion that can be fitted with the groove of the upper part 110 and the groove of the lower part 120 of the main body. Note that the attachment 111 of the present embodiment is attached to both the upper part 110 and the lower part 120 of the main body, but it may be attached to either one of the upper part 110 and the lower part 120 of the main body.

[0031] The groove for holding the substrate is a recess formed between groove side walls 114 protruding from the surface of the attachment 111 (the surface not in contact with the upper part 110 of the main body). The end portions in the width direction of the substrate can be held by the groove for holding the substrate. The groove for holding the substrate extends from the upper end on the lid body 30 side of the attachment 111 to the lower end on the lower part 20 side of the main body, and is arranged in a plurality of rows parallel to each other.

[0032] The substrate size adjustment spacer 112 is a member that adjusts the distance between the bottom surfaces of two opposing substrate holding grooves so as to correspond to the widthwise size of the substrate to be stored. Note that the heightwise size of the substrate to be stored is adjusted corresponding to the heightwise length of the main body upper portion 110 and the heightwise length of the attachment 111. Thereby, the length of the substrate holding groove and the heightwise length of the substrate size adjustment spacer 112 become corresponding to the heightwise size of the substrate to be stored. The substrate packaging box of the present embodiment can accommodate various types of substrates having different widthwise sizes and heightwise sizes by replacing the attachment 111 provided with the substrate holding groove and the substrate size adjustment spacer 12 provided in a specific size.

[0033] The main body lower portion 120 is a member having a substantially rectangular opening at the upper portion and having a side wall portion forming four side surfaces and a bottom portion forming a bottom surface, and does not have an upper surface. Further, the main body lower portion 120 has a structure for fixing the attachment 111 on two opposing surfaces out of the four surfaces constituting the inner side (inner surface of the side surface) of the side wall portion of the main body lower portion 120. The structure for fixing the attachment 111 is not particularly limited, and examples thereof include a groove that can be fitted with a convex portion of the attachment 111. This groove is disposed at a position connected to the groove for fixing the attachment 111 of the main body upper portion 110. As described above, the bottom surface (inner surface of the bottom portion) 21 of the main body lower portion 120 has a second groove 24 for holding a substrate, and this second groove 24 is disposed at a position facing the groove disposed on the inner surface of the lid body 30. The second groove 24 for holding a substrate in the main body lower portion 120 is a recess formed between groove side walls 22 protruding from the bottom surface 21. Further, a handle 26 may be provided on the outer surface of the side wall portion of the main body lower portion 120. The side surface on which the handle 26 is provided is not particularly limited, and it may be provided on only one side surface, two side surfaces, three side surfaces, or four side surfaces, but it is preferably provided on two opposing side surfaces in terms of ease of handling.

[0034] According to this embodiment, by adjusting the dimensions of the upper body 110 and the attachment 111 according to the size of the substrate, for various types of substrates with different sizes, while the lid 30, the upper body 110, and the lower body 120 can be commonly used, a substrate packaging box corresponding to the storage of various types of substrates can be provided. That is, by configuring the substrate packaging box with parts that can be diverted for substrates of any size (the upper body 110, the lower body 120, and the lid 30) and parts that change the position of the groove for holding the substrate according to the size of the substrate (the attachment 111), the volume of the constituent members of the substrate packaging box required for storing various types of substrates can be reduced, and the storage space for the substrate packaging box can be reduced.
