[Detailed description of the invention] This invention relates to a cardboard document holder.
To enable drawings, etc. to be rolled up into a cylindrical shape and stored, and to extremely easily take in and out the drawings, etc.

The present invention will be explained below based on drawings showing embodiments. First, a first embodiment will be explained based on FIGS. 1 to 9. In the figure, reference numerals 1 and 2 are two corrugated cardboard plates forming a rectangular cylindrical document case, and both plates 1 and 2 are respectively bent into a planar shape and combined with each other to form a rectangular cylindrical document case. . First, as shown in FIGS. 1 and 3, one of the plate bodies 1 has a vertically long rear plate 3 and left and right outer plates 4 and 5 which are connected to both sides of the rear plate 3 and are vertically long. , bending pieces 6 to 8 that are connected to the upper ends of the rear plate 3 and the left and right outer plates 4 and 5 and are bent so as to overlap the inner surfaces of the upper ends of each of the plates 3 to 5; Bottom plate forming flaps 9 to 11 connected to the lower end, and engaging pieces 12 and 1 formed at the free ends of the left and right outer plates 4 and 5 in the vicinity of both upper and lower ends of the left and right outer plates 4 and 5, respectively.
2, 13, and 13. As shown in FIGS. 2 and 3, the other plate 2 includes a front plate 14 that is long in the vertical direction, and is connected to both sides of the front plate 14, and is long in the vertical direction and has a vertically long front plate 14. Left and right inner plates 15 and 16 overlapping the inner surfaces of the left and right outer plates 4 and 5
, an upper lid forming plate portion 17 connected to the upper ends of the front plate 14 and the left and right inner plates 15 and 16, and a folding line 18 formed near the upper end of the front plate 14;
The left and right inner plates 1 are connected to both ends of the folding line 18.
Slits 19 and 20 are formed in the vicinity of the upper ends of the folding line 18 so as to gradually incline upward from both ends of the folding line 18, and slits 19 and 20 are formed in the vicinity of the upper ends of the one plate body 1 below the positions where the slits 19 and 20 are formed. Engagement piece 1
Engagement holes 21, 21, 22, 2 formed near the connection line of the left and right inner plates 15, 16 with respect to the front plate 14 at positions corresponding to 2, 12, 13, 13
2, and between these engagement holes 21, 21 and 22, 22
The front plate 14 and the left and right inner plates 15 are located in between,
a front cover 25 having a substantially semicircular side surface formed with a bent piece 23 and a slit 24 on the front plate 16; and a bottom plate forming flap 2 connected to the lower end of the front plate 14.
It is formed from 6.

More specifically, each of the engaging pieces 12 and 13 of the one plate body 1 has central plate parts 12a and 13a which are bendably connected to the left and right outer plates 4 and 5, and the plate part 1.
It consists of both side plate portions 12b, 12b, 13b, 13b which are bendably connected to both sides of 2a, 13a. Therefore, the engagement pieces 12 and 13 have both end plate portions 12b, 12b, 13b, and 13b bent relative to the central plate portions 12a and 13a, and the engagement holes in the other plate body 2 are opened in the engagement holes 21 and 13, respectively. 22, and after the insertion, both side plate portions 12b, 12b, 13b, 13b return to their original states due to the elasticity of the corrugated board, and can be engaged with the engaging pieces 21, 22. The upper lid forming plate part 17 of the other plate body 2 has an upper plate 27 connected to the upper end of the front plate 14, and a top plate 27 connected to the tip of the upper plate 27 and bent to the lower side of the upper plate 27. lower plate 28
and a middle plate 29 which is integrally connected to the upper ends of the left and right inner plates 15 and 16 and to both left and right sides of the upper plate 27, is bent in half and is sandwiched between the upper plate 27 and the lower plate 28. , 30, and finger holes 27a, 28a are formed in the center of both the upper and lower plates 27, 28 and communicate with each other. The upper lid forming plate portion 17 configured in this manner, the portion of the front plate 14 above the folding line 18, and the slit 19,
Upper left and right inner plates 15 and 16 above 20 form an upper lid 35 that can be opened and closed. A protective sheet 31 is attached to the inner surface of the front plate 14 to protect the folding line 18 at the position where the folding line 18 is formed. The front lid 25 also includes a center plate portion 32 formed by cutting out a part of the front plate 14 and the left and right inner plates 15 and 16, and whose lower end is connected to the front plate 14 in a bendable manner, and this center plate. It consists of semicircular side plate portions 33 and 34 connected to both sides of the central plate portion 32, and a finger rest recess 32a is formed at the center of the upper end of the center plate portion 32. Furthermore, the three bottom plate forming flaps 9 to 11 of the one plate 1 and the one bottom plate forming flap 26 of the other plate 2 have a triangular shape, and the four triangular bottom plates Formation flap 9
The bottom plate 36 is formed by engaging the parts 11 and 26 as shown in FIG.

By the way, when the two plates 1 and 2 are connected to each other, as shown in FIGS. 4 and 7, the upper ends of the left and right inner plates 15 and 16 of the other plate 2 are connected to the one plate 1. is sandwiched between the left and right outer plates 4, 5 and the bent pieces 7, 8. Further, both left and right sides of the upper lid 35 can be fitted inside the bent pieces 7 and 8. Further, the side plate portions 33 and 34 of the front lid 25 overlap the inner surfaces of the left and right outer plates 4 and 5 of one plate body 1.

The rectangular cylindrical document case constructed as described above is the eighth
A large number of containers are stored in parallel in a cardboard collection box 37 constructed as shown in FIG. 9 and FIG. The collection box 37 has two sets of opposing side plates 39, 39, 40, 40 on the long side and the short side in order to store the square cylindrical document containers 38 in two rows.
Bottom plate forming flaps 41, 41, 42, 42 connected to the lower ends of each side plate 39, 39, 40, 40
and protective folding pieces 43, 43, 44, 44 which are connected to the upper ends of the side plates 39, 39, 40, 40 and overlap the inner surfaces of the upper ends of the side plates 39, 39, 40, 40. Therefore, one of the rectangular cylindrical document cases 38 stored in this collection box 37 is taken out from the collection box 37 by hooking one's fingers into the finger hook holes 27a and 28a, and then inserted into the taken out document case 38. Insert or remove a drawing rolled into a cylinder. In this case, if the drawing is long and its upper end reaches near the top cover 35, the top cover 35 is opened to take in and take out the drawing. Also, as shown in Figure 7, if the drawing 45 is short, place the drawing 45 in the document case 3.
They can be stacked in two tiers within the container 8, and can be inserted by opening the top lid 35. Note that the lower drawing 45 can also be inserted by opening the front lid 25. In addition, when drawing the drawings 45 stacked in two levels, open the top cover 35 for the upper drawing 45, and then remove the drawing 45 from the lower side.
Step 5 is performed by opening the front lid 25.

Next, a second embodiment shown in FIGS. 10 to 14 will be described. That is, in this second embodiment, the upper end of the rectangular cylindrical document holder 38a is tilted toward the rear, and the other configuration of the document holder 38a is the same as that of the first embodiment. The collection box 37a is configured to accommodate one row of each of the rectangular cylindrical document holders 38a in the second embodiment and the prismatic cylindrical document holders 38 in the first embodiment, and the schematic structure is shown in FIGS. It is approximately the same as that shown in FIG.

The cardboard document holder of the present invention can be implemented as described above, and drawings, etc. can be stored in a rolled-up cylindrical state, and the drawings, etc. can be taken in and out very easily. Furthermore, assembly can be easily carried out without using any fixing means such as glue, and an inexpensive document holder can be provided.
