DETAILED DESCRIPTION OF THE INVENTION

[0012] The following describes an embodiment of the present invention with reference to the accompanying drawings. The accompanying drawings are an example of an embodiment of the invention, and in the drawings, parts with the same reference numerals represent the same objects. Furthermore, the shapes and dimensional ratios of each part in each drawing are not necessarily accurate.

[0013] <Overall structure> As shown in Fig. 1, the packaging box 1 for plate members according to the embodiment of the present invention is for storing plate members 100. Examples of the plate members 100 include fragile plate members such as marble plates and glass plates, but the plate members 100 are not limited to these and may be other plate members.

[0014] The packaging box 1 for plate members in this embodiment has an internal storage space 10 capable of storing plate members 100, and has a thin rectangular parallelepiped shape, while being open to the outside through an opening 27. Specifically, the packaging box 1 for plate members includes a side wall portion 2, a bottom portion 3, and a lid portion 4.

[0015] 1, the board member packing box 1 is defined as having a height direction H along the height direction of the side wall portion 2, a width direction W perpendicular to the height direction H, and a depth direction D. Since the board member packing box 1 has a thin rectangular parallelepiped shape, the depth is smaller than the width.

[0016] <Side wall> The side wall portion 2 will be described below with reference to Fig. 1. As shown in the plan view of Fig. 3(A), the side wall portion 2 in this embodiment is configured in a cylindrical shape (specifically, a rectangular cylindrical shape). Therefore, both ends of the side wall portion 2 in the height direction are open. As shown in Fig. 2, the side wall portion 2 has a pair of first side wall pieces 21 and a pair of second side wall pieces 23.

[0017] <Pair of first side wall pieces> The pair of first side wall pieces 21 are formed of a laminate (first laminate) 50 made by stacking multiple sheets of cardboard. The laminate 50 is a plate-like body. By making the first side wall pieces 21 out of the cardboard laminate 50, the strength and cushioning properties of the first side wall pieces 21 are improved, thereby reducing the impact and vibration that are applied to the packed plate member 100.

[0018] 1 to 3, the stack 50 is formed by stacking three sheets of corrugated cardboard, but this is not limited thereto, and the number of sheets of corrugated cardboard in the stack 50 is determined depending on the required strength and degree of shock absorption. The corrugated cardboard that makes up the stack 50 may be double-flute cardboard made of C5 material, but this is not limited thereto, and other types of corrugated cardboard, such as single-flute cardboard made of other materials, may also be used. Furthermore, the size of the corrugated cardboard that makes up the stack 50 may be, for example, 1290 mm wide, 600 mm high, and 3 mm thick, but other sizes may also be used.

[0019] As shown in FIG. 3(A), the pair of first side wall pieces 21 (stacked body 50) are arranged to face each other with a gap in between in the depth direction D. In this case, the stacking direction of the cardboards of the stacked body 50 coincides with the depth direction D. Also, as shown in FIG. 3(A), each cardboard that makes up the stacked body 50 is oriented so that the corrugated shape that forms the core extends along the width direction W.

[0020] The pair of second side wall pieces 23 are formed of a laminate (second laminate) 52 made by stacking multiple sheets of corrugated cardboard. In Figures 1 to 3, the laminate 52 is a rod-like body with a substantially rectangular cross section when cut perpendicular to the longitudinal direction of the laminate 52, but this is not limited to this and it may be a plate-like body depending on the size of the plate member 100. By forming the second side wall pieces 23 as the corrugated cardboard laminate 52, the strength and cushioning properties of the second side wall pieces 23 are improved, and therefore the impact and vibration applied to the packed plate member 100 can be reduced.

[0021] 1 to 3, stack 52 is formed by stacking three sheets of corrugated cardboard, but this is not limited to this, and the number of sheets of corrugated cardboard in stack 52 is determined depending on the required strength and degree of shock absorption. Examples of corrugated cardboard that constitutes stack 52 include double-flute corrugated cardboard made of C5 material, but this is not limited to this, and other types of corrugated cardboard, such as single-flute corrugated cardboard made of other materials, may also be used. Furthermore, examples of the size of the corrugated cardboard that constitutes stack 52 include corrugated cardboard with a width of 30 mm, a height of 550 mm, and a thickness of 3 mm, but other sizes may also be used.

[0022] As shown in FIG. 3(A), the pair of second side wall pieces 23 (stacked body 52) are arranged to face each other with a gap in the width direction W. In this case, the stacking direction of the cardboards in stacked body 52 coincides with the depth direction D. Furthermore, as shown in FIG. 3(B), each cardboard that makes up stacked body 52 is oriented so that the corrugated shape that forms the core extends along the height direction H.

[0023] The pair of second side wall pieces 23 are arranged so as to be interposed between the pair of first side wall pieces 21 at both ends of the pair of first side wall pieces 21 in the width direction, and are connected to the pair of first side wall pieces 21 with an adhesive or the like. At this time, the pair of second side wall pieces 23 are arranged so that an area R in which the bottom portion 3 is to be placed is secured directly below the pair of second side wall pieces 23.

[0024] The space surrounded by the pair of first side wall pieces 21 and the pair of second side wall pieces 23 becomes the storage space 10 for the plate member 100. When the plate member 100 is stored in the storage space 10, the innermost corrugated cardboard 210 of the pair of first side wall pieces 21 faces both flat surface portions 101, 102 of the plate member 100 (see FIG. 1), and the pair of second side wall pieces 23 faces both thick surface portions 103, 104 of the plate member 100 (see FIG. 1).

[0025] Considering the work involved in storing the plate member 100 in the plate member packaging box 1, it is preferable that there be a small gap between the plate member 100 and the innermost cardboard 210 of the pair of first side wall pieces 21 and between the plate member 100 and the innermost surface of the pair of second side wall pieces 23. However, it is preferable that the gap be such that rattle of the plate member 100 is minimized.

[0026] <Bottom part> The bottom surface portion 3 closes one opening (first opening) 25 (see FIG. 3(B)) of the side wall portion 2. The bottom surface portion 3 is composed of a laminate (third laminate) 54 made by stacking multiple sheets of corrugated cardboard. In FIGS. 1 to 3, the laminate 54 is a rod-like body whose cross section cut perpendicular to the longitudinal direction of the laminate 54 is substantially rectangular, but this is not limited to this and the laminate 54 may be a plate-like body depending on the size of the plate member 100. By using the cardboard laminate 54 for the bottom surface portion 3, the strength and cushioning properties of the bottom surface portion 3 are improved, thereby reducing the impact and vibration that may be applied to the packed plate member 100.

[0027] 1 to 3, stack 54 is formed by stacking three sheets of corrugated cardboard, but this is not limited to this, and the number of sheets of corrugated cardboard stacked in stack 54 is determined depending on the required strength and degree of shock absorption. Examples of corrugated cardboard that constitutes stack 54 include double-flute corrugated cardboard made of C5 material, but this is not limited to this, and other types of corrugated cardboard, such as single-flute corrugated cardboard made of other materials, may also be used. Furthermore, examples of the size of the corrugated cardboard that constitutes stack 54 include corrugated cardboard with a width of 1290 mm, a height of 50 mm, and a thickness of 3 mm, but other sizes may also be used.

[0028] As shown in FIG. 3(C), the bottom surface portion 3 is disposed in region R so as to be interposed between the pair of first side wall pieces 21 at the lower ends in the height direction of the pair of first side wall pieces 21 and contact the lower ends in the height direction of the pair of first side wall pieces 21 and the pair of second side wall pieces 23, and is connected to the pair of first side wall pieces 21 and the pair of second side wall pieces 23 with an adhesive or the like. At this time, the stacking direction of the cardboard sheets in the stack 54 coincides with the depth direction D. As a result, the stacking direction of the cardboard sheets in the stack 54 coincides with the stacking direction of the cardboard sheets in the stacks 50 and 52. Furthermore, each cardboard sheet in the stack 54 is oriented so that the corrugated shape forming the core extends along the width direction W.

[0029] The bottom surface portion 3 supports the plate member 100. Therefore, the length of the bottom surface portion 3 in the height direction H is determined taking into consideration the load received from the plate member 100.

[0030] <Lid> The lid portion 4 is configured to be able to open and close the other opening (second opening) 27 of the side wall portion 2. The lid portion 4 is continuous with the upper end of the side wall portion 2 in the height direction H.

[0031] Specifically, the lid portion 4 is formed of a lid-side corrugated cardboard (second corrugated cardboard) 40 that is continuous with the outermost corrugated cardboard (first corrugated cardboard) 212 of the stack 50 that forms the first side wall piece 21 at one end (top end) in the height direction H of the outermost corrugated cardboard 212. The outermost corrugated cardboard 212 and the lid-side corrugated cardboard 40 are preferably formed from a single piece of corrugated cardboard. A fold line 42 is formed on the single piece of corrugated cardboard at the boundary between the outermost corrugated cardboard 212 and the lid-side corrugated cardboard 40. As shown in FIG. 3(C), the lid-side corrugated cardboard 40 bends relative to the outermost corrugated cardboard 212 at the fold line 42 and tilts toward the other opening 27 of the side wall portion 2, closing the opening 27. When opening 27, the lid-side corrugated cardboard 40 is swung about the fold line 42 so that it stands up. In other words, the lid-side corrugated cardboard 40 is configured to be able to open and close the opening 27 by swung about the fold line 42.

[0032] The lid portion 4 is not limited to being continuous with the outermost corrugated cardboard 212 of the stack 50, but may be continuous with a corrugated cardboard at another position constituting the stack 50, or may be continuous with multiple corrugated cardboards of the stack 50. As a result, the lid portion 4 may be formed from a stack of multiple corrugated cardboards, or may be formed from a single corrugated cardboard. The lid portion 4 may be provided on one or both of the pair of first side wall pieces 21. In either case, the corrugated cardboard that forms at least a part of the stack 50 and is continuous with the lid-side corrugated cardboard (second corrugated cardboard) 40 may be called the first corrugated cardboard to distinguish it from other corrugated cardboards.

[0033] <Packaging method for plate components> To pack the plate member 100 in the plate member packing box 1, there are a first packing method in which the plate member 100 is lifted and inserted into the plate member packing box 1, and a second packing method in which the plate member packing box 1 is lifted and the plate member packing box 1 is placed over the plate member 100.

[0034] In the first packaging method, after inserting the plate member 100 into the storage space 10 of the plate member packaging box 1, the lid portion 4 is closed and fixed to the side wall portion 2 with tape or the like. The first packaging method is effective when the plate member 100 is light in weight.

[0035] In the second packaging method, the plate member packaging box 1 is lifted and placed over the plate member 100 so that the plate member 100 is inserted into the storage space 10, and then the position of the plate member packaging box 1 is changed so that the opening 27 faces upward. Thereafter, the lid portion 4 is closed and fixed to the side wall portion 2 with tape or the like. The second packaging method is effective when the plate member 100 is heavy.

[0036] In both the first and second packaging methods, the plate members 100 can be packaged mainly using only the plate member packaging box 1, so that the effort and time required for the packaging work can be reduced.

[0037] The packaging box for plate members of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made within the scope of the present invention without departing from the gist of the present invention.
