The cases were configured such that they could be joined together and the overlapping folded halves on each side could be joined together.

(Effects) In the case according to the first aspect of the present invention, the case can be configured by folding a square sheet, which is the outer skin of the case, in half. At this time, cases of different sizes can be formed depending on the direction of folding.

For example, assuming that the ratio of the side to the end of the rectangular sheet is 4: 2, if the sheet is folded in half along a straight line connecting the respective centers of the opposing ends, a case of a ratio of 4: 1 is obtained. When folded in half along a straight line connecting the approximate centers on both sides, a case of a ratio of 2 to 2 in length and width is obtained. Furthermore, if this is folded in half, it will be 2/4 in length and width, one-quarter the area of the original sheet.
This is a one-to-one case.

At each end and each side of the rectangular sheet, a lid piece protrudes from a half of an end and a side divided at the center.
The lid pieces protrude so as not to be adjacent to each other with the vertex between the end and the side interposed therebetween, so that the half of the protruding end (side) of the lid piece with the vertex in between and the side without the lid piece ( Half of the edge) is adjacent. Each lid piece is bendable with respect to the sheet.

Furthermore, the halves of each bent end overlap each other, and the upper right end without the lid, the lower right end with the lid, and the upper left end with the lid and the lower left without the lid are A case of one size is completed by bending each lid piece, coupling the coupling means and the coupled means, and closing the open end.

In a state of being folded in half along a straight line connecting the respective centers of the opposing sides, the opposing ends are superimposed, and the upper right end without the lid, the upper left end with the lid, and the lid A certain lower right end portion and a lower left end portion without a lid piece are folded and the coupling means and the coupled means are coupled to each other by folding the lid piece, so that the opposite ends are closed and the cylindrical object is closed. Can be formed. Furthermore, the folded halves overlap each other, and the upper right part and the upper left part, and the lower right part and the lower left part are respectively connected to close the opening of the cylindrical body, Cases of other sizes are completed.

Since the two differently sized cases formed in this way can be further folded in half, the case according to the invention of claim 1 can selectively use three sizes with one. It has the advantage of being able to.

In the case according to the second aspect of the present invention, the rectangular sheet that is the outer skin of the case has flexibility, so that it is folded in half, and each end and each of the two ends are similar to the case according to the first aspect of the present invention. A case can be constructed by joining the sides. At that time, depending on which direction to fold,
Cases of different sizes can be configured and can be folded in half, so that one can selectively use three sizes.

In the case according to the third aspect of the present invention, the rectangular sheet that is the outer skin of the case is formed by connecting four identical rectangular partial sheets by substantially touching one of the vertices of each partial sheet. It is configured to be foldable in half along a straight line connecting the respective centers of the opposite ends, and is connected so as to be foldable in half along a straight line connecting the respective centers of the opposite sides.

9, 10, and 11 are provided.

Each male hook 6a, 6b, 6c, 6d and each female hook 7a, 7b, 7c, 7d are arranged such that the other hooks are adjacent to each other, with each vertex 1a, 1b, 1c, 1d of the base 1 interposed therebetween. Are located in That is,
The peripheral edge of the base 1 is turned counterclockwise in FIG.
Female hook 7a, vertex 1a, male hook 6b, female hook 7b, vertex 1d, male hook 6c, female hook 7c, vertex 1c, male hook 6d, female hook 7d,
Vertex 1d is arranged in order.

Each male hook 6 can be repeatedly connected to and removed from at least the female hook provided on the same side and the female hook provided on the opposite side. I.e. male hook
6a can be connected to the female hook 7a on the same side and the female hook 7c on the opposite side. In this embodiment, each male hook 6 and each female hook 7 are of the same type.

Since the base 1 is made of a flexible vinyl sheet,
It can be bent freely. Therefore, the base 1 has two center lines C1, C
2 can be folded to have half the area of the original base 1.

 Next, the operation of the present embodiment will be described.

As described above, the base 1 can be bent along the two center lines C1 and C2. The center line C1 in the development of FIG.
FIG. 3 shows a state in which the short sides 4 and 5 are folded along a valley according to FIG. In addition, in the developed view of FIG. 1, a state in which the long sides 2 and 3 are bent along the center line C2 along the center line C2 is shown in FIG.

Further, if the male hook 6a and the female hook 7a, the male hook 6c and the female hook 7c at the end of the cylindrical member are bent and connected to the lid pieces 8 and 10, respectively, the size of the original base 1 is reduced to half. The case for accommodating the sheet-like material is formed.

For example, if the original base 1 is B4 size,
It is a size that just fits the thing of the size.

From the state where the four lid pieces 8 to 11 are closed, the connection between any one of the male hook 6 and the female hook 7 is removed, and the articles are put in and closed again, whereby the articles are stored.

In FIG. 4, the base 1 bent along C2
Are the long sides 2 and 3 facing each other, and the vertices 1b and 1a,
Vertex 1c and vertex 1d overlap. In this state, the base 1 is half of the original area, but is folded into an elongated shape as compared with the case where the base 1 is folded along the center line C1 shown in FIG.
The long side 2 (3) center line C2 of the original base 1 forms a side, and the short sides 4, 5 of the original base 1 are folded in half to form an end.

In this state, when the male hook 6a and the female hook 7c, and the male hook 6c and the female hook 7a at the side portions are connected by bending the lid pieces 10 and 8, respectively, an elongated cylindrical body having both open ends is formed. Further, if the male hook 6b and the female hook 7b, and the male hook 6d and the female hook 7d at the ends of the elongated cylindrical body are joined by bending the lid pieces 9 and 11, respectively, one half of the original base 1 can be obtained. A case for storing an elongated article having a size is formed.

Further, when the folded object shown in FIGS. 3 and 4 is folded again, a case having a quarter of the area of the original base 1 as shown in FIGS. 5 and 6 is formed. .

When the case folded into the shape shown in FIG. 3 is folded along a valley along C2, the shape becomes as shown in FIG. The back surface is shown in FIG. For example, if the original base 1 is B4 size, by removing the male hook 6c and the female hook 7c and opening the lid piece 10, or by removing the male hook 6d and the female hook 7d and opening the lid piece 11 , B6 size sheet-like objects can be accommodated.

When the case folded into the shape shown in FIG. 4 is folded along the valley along C1, the male hook 6a and the female hook 6a
The articles are stored by removing the lid 7 and removing the lid 10 or by removing the male hook 6d and the female hook 7b and opening the lid 11.

Therefore, the sheets 20a and 20c are the same, the sheets 20b and 20d are the same, and there are two sheets of two types each.

The four sheets 20a to 20d are composed of a lid piece 21, a female hook 2
2. The vertices formed by the sides on which the male hooks 23 are not provided are collected at one point, and are arranged such that sheets of different types are arranged side by side. The sheets 20a to 20d are joined to each other by a flexible cloth tape.

Therefore, the case of this embodiment can be folded in half on the cloth tapes 24 and 25 similarly to the embodiment shown in FIGS. 1 to 6, and each female hook 22 and each male hook 23 are joined to each other. By closing the lid piece 21, it is possible to configure a form for storing articles.

Further, each lid piece 21 is provided with a folding margin 26a, 26b, 26c, 26d, and when the lid piece 21 is bent to connect the male hook 22 and the female hook 23, each folding margin 26 is , Each sheet
It is orthogonal to 20 and each lid piece 21, and therefore has the thickness of the case.
Therefore, more articles such as documents can be stored.

Also, the case according to the present invention can be combined into a single case by combining a plurality of cases.

FIG. 8 shows a composite case in which two cases of the embodiment shown in FIGS. 1 to 6 are combined.

In the figure, of the two cases constituting the composite case, members of the case constituting the rear surface of the composite case are shown with dashes.

That is, the female hook 6a and the male hook 7a ', 6b and 7b', 6c and 7c ', and 6d and 7d' are connected to the connecting members of both cases.
Male hooks 7a and 6a ', 7d and 6b', 7c and 6c ', 7b and 6d'
Are combined.

By configuring a composite case by combining a plurality of cases in this way, a sheet having the same dimensions as the case can be stored. For example, if the base is a B4 size, it is possible to store a B4 size sheet by combining the two cases as shown in FIG. As mentioned earlier, the case of base size B4,
We were able to store B5 size items in half, and B6 size items in quarter, but by combining multiple same cases,
B4 size and B3 size can be supported by combining four cases, which is very versatile.
