One embodiment of the present invention is described below.

First, with reference to Figures 1 and 2, we will explain the sheet container 100 according to one embodiment of the present invention.

The sheet container 100 is configured to store a plurality of folded sheets 3 impregnated with a liquid (e.g., a medicinal liquid) in a stacked state. As shown in FIG. 1, the sheet container 100 includes a bag-shaped container body 110 and a lid member 120 provided on the container body 110.

The container body 110 has an internal space for storing multiple folded sheets 3 (see FIG. 2). The container body 110 is formed, for example, using a laminated film, and is flexible and configured to be impermeable to liquids. An opening (not shown) is formed on the upper surface 111 of the container body 110, and a lid member 120 is provided to cover the opening.

The lid member 120 is provided to seal the internal space of the container body 110 and to enable removal of the folding sheet 3 from the internal space. The lid member 120 is integrally formed from resin. As shown in FIG. 2, the lid member 120 includes a base portion 121 attached to the upper surface 111 of the container body 110, an outlet 122 formed in the base portion 121, a lid body 123 that opens and closes the outlet 122, and a hinge portion 124 that rotatably connects the lid body 123 to the base portion 121.

The base portion 121 is formed in a plate shape and is provided to close the opening of the top surface 111. The removal opening 122 is formed to penetrate the base portion 121 and is provided to open the internal space of the container body 110. This allows the user to remove the folding sheet 3 from the internal space through the removal opening 122. The lid body 123 is provided rotatably on the base portion 121 via a hinge portion 124.

As shown in FIG. 1, when the lid 123 closes the removal opening 122, the internal space of the container body 110 is sealed, and as shown in FIG. 2, when the lid 123 opens the removal opening 122, the folding sheet 3 can be removed. The hinge portion 124 is disposed at the upper end (the end on the Y1 direction side) of the base portion 121, and is formed to extend in the left-right direction (X1 and X2 directions). That is, the axial direction of the rotation shaft of the hinge portion 124 faces the left-right direction.

Here, in the sheet container 100, the folding sheet 3 is contained in the container body 110 so that sides 11 and 12 (described later) of the folding sheet 3 appear at the removal opening 122 and face in the left-right direction. In other words, the sides 11 and 12 of the folding sheet 3 face in the same direction as the axial direction of the rotation shaft of the hinge portion 124.

-Method of forming a folding sheet-
Next, a method of forming the folded sheets 3 to be stored in the sheet storage body 100 will be described with reference to FIGS.

The foldable sheet 3 is formed by folding the sheet material 1. The sheet material 1 is made of, for example, a nonwoven fabric, is capable of being impregnated with liquid, and is configured to be foldable. As shown in FIG. 3, the sheet material 1 is rectangular and has sides 11 to 14. Sides 11 and 12 are the long sides, and sides 13 and 14 are the short sides.

Sides 11 and 12 are disposed opposite each other and are formed to extend parallel to the left-right direction (X1 and X2 directions). Sides 13 and 14 are disposed opposite each other and are formed to extend parallel to the up-down direction (Y1 and Y2 directions). Side 13 is formed to connect one end (end on the X1 direction side) of side 11 to one end (end on the X1 direction side) of side 12. Side 14 is formed to connect the other end (end on the X2 direction side) of side 11 to the other end (end on the X2 direction side) of side 12. Sides 11, 12, 13, and 14 are examples of the "first side", "second side", "third side", and "fourth side" of the present invention, respectively.

In the method for forming the folding sheet 3 according to this embodiment, the sheet material 1 is first folded along the first fold F1 and the second fold F2. The first fold F1 connects a point P1 that is the closest to side 13 among the points obtained by dividing side 11 into four equal parts, and a point P2 that is the closest to side 13 among the points obtained by dividing side 12 into four equal parts. The second fold F2 connects a point P3 that is the closest to side 14 among the points obtained by dividing side 11 into four equal parts, and a point P4 that is the closest to side 14 among the points obtained by dividing side 12 into four equal parts. The first fold F1 and the second fold F2 extend parallel to sides 13 and 14. At the second fold F2, the sheet material 1 is folded in the opposite direction to the first fold F1. For example, the left portion of sheet material 1 is moved in the R1 direction (back side) so as to overlap with the center portion of sheet material 1, and the right portion of sheet material 1 is moved in the R2 direction (front side) so as to overlap with the center portion of sheet material 1.

As a result, as shown in FIG. 4, the sheet material 2 is formed in a state in which the surface portions 22 and 23 are overlapped with the surface portion 21. The surface portion 21 is the surface between the first fold F1 and the second fold F2, the surface portion 22 is the surface between the first fold F1 and the side 13, and the surface portion 23 is the surface between the second fold F2 and the side 14. The surface portion 22 is disposed on one side (opposite to the Z direction) of the surface portion 21, and the surface portion 23 is disposed on the other side (Z direction side) of the surface portion 21. The sheet material 2 is folded back at the first fold F1 and the second fold F2 so that the sides 13 and 14 are aligned in the left-right direction (X1 and X2 directions). The surfaces 21, 22, and 23 are examples of the "first surface portion," "second surface portion," and "third surface portion" of the present invention, respectively.

Next, the sheet material 2 is folded along the third fold F3 and the fourth fold F4. The third fold F3 connects a point P5 that is the closest to the side 11 among the points obtained by dividing the first fold F1 into four equal parts, and a point P6 that is the closest to the side 11 among the points obtained by dividing the second fold F2 into four equal parts. The fourth fold F4 connects a point P7 that is the closest to the side 12 among the points obtained by dividing the first fold F1 into four equal parts, and a point P8 that is the closest to the side 12 among the points obtained by dividing the second fold F2 into four equal parts. The third fold F3 and the fourth fold F4 extend parallel to the sides 11 and 12. The fourth fold F4 is folded to the same side as the third fold F3. For example, the upper part of the sheet material 2 is moved in the R3 direction (towards the front side) so as to overlap with the central part of the sheet material 2, and the lower part of the sheet material 2 is moved in the R4 direction (towards the front side) so as to overlap with the central part of the sheet material 2.

In this way, the folded sheet 3 is formed as shown in Figures 5 and 6. The folded sheet 3 is folded back at the third fold F3 and the fourth fold F4 so that the sides 11 and 12 are aligned in the vertical direction (Y1 and Y2 directions).

- Folding seat structure -
Next, the structure of the folding sheet 3 will be described with reference to Figures 5 to 7. In Figure 7, the valley folds are indicated by dashed lines and the mountain folds are indicated by dashed two-dot lines.

The folding sheet 3 is folded so that the area of the sheet material 1 is reduced to 1/4. As shown in FIG. 7, the folding sheet 3 has surface portions 31a, 31b, 31c, 32a, 32b, 32c, 33a, 33b, and 33c.

Surface portion 31a is defined by the first fold F1, the second fold F2, the third fold F3, and the fourth fold F4, surface portion 31b is defined by side 11, the first fold F1, the second fold F2, and the third fold F3, and surface portion 31c is defined by side 12, the first fold F1, the second fold F2, and the fourth fold F4. Surface portion 32a is defined by side 13, the first fold F1, the third fold F3, and the fourth fold F4, surface portion 32b is defined by side 11, side 13, the first fold F1, and the third fold F3, and surface portion 32c is defined by side 12, side 13, the first fold F1, and the fourth fold F4. Surface portion 33a is defined by side 14, the second fold F2, the third fold F3, and the fourth fold F4, surface portion 33b is defined by side 11, side 14, the second fold F2, and the third fold F3, and surface portion 33c is defined by side 12, side 14, the second fold F2, and the fourth fold F4.

The areas of surface portions 31b, 31c, 32a, and 33a are the same, and the areas of surface portions 32b, 32c, 33b, and 33c are the same. The area of surface portion 31a is 1/4 of the area of sheet material 1. The areas of surfaces 31b, 31c, 32a, and 33a are 1/2 of the area of surface portion 31a. The areas of surfaces 32b, 32c, 33b, and 33c are 1/4 of the area of surface portion 31a.

The left end (X1 direction end) of the surface 31a is connected to the left end of the surface 32a via the first fold F1, and the right end (X2 direction end) of the surface 31a is connected to the right end of the surface 33a via the second fold F2. The upper end (Y1 direction end) of the surface 31a is connected to the upper end of the surface 31b via the third fold F3, and the lower end (Y2 direction end) of the surface 31a is connected to the lower end of the surface 31c via the fourth fold F4. The upper end of the surface 32a is connected to the upper end of the surface 32b via the third fold F3, and the lower end of the surface 32a is connected to the lower end of the surface 32c via the fourth fold F4. The upper end of the surface 33a is connected to the upper end of the surface 33b via the third fold F3, and the lower end of the surface 33a is connected to the lower end of the surface 33c via the fourth fold F4. The left end of surface 31b is connected to the left end of surface 32b via a first fold F1, and the right end of surface 31b is connected to the right end of surface 33b via a second fold F2. The left end of surface 31c is connected to the left end of surface 32c via a first fold F1, and the right end of surface 31c is connected to the right end of surface 33c via a second fold F2.

In the upper left part of the folding sheet 3 (see Figures 5 and 6), the surfaces 32a, 31a, 31b, and 32b are stacked in this order in the thickness direction (Z direction). In the lower left part of the folding sheet 3, the surfaces 32a, 31a, 31c, and 32c are stacked in this order in the thickness direction (Z direction). In the upper right part of the folding sheet 3, the surfaces 31a, 33a, 33b, and 31b are stacked in this order in the thickness direction (Z direction). In the lower right part of the folding sheet 3, the surfaces 31a, 33a, 33c, and 31c are stacked in this order in the thickness direction (Z direction).

-effect-
As described above, this embodiment includes a step of folding the left portion of the sheet material 1 along the first fold F1 and a step of folding the right portion of the sheet material 1 to the opposite side along the second fold F2, and a step of folding the upper portion of the sheet material 2 along the third fold F3 and a step of folding the lower portion of the sheet material 2 to the same side along the fourth fold F4. By configuring in this way, it is possible to form a folded sheet 3 that is easily unfolded when removed from the sheet container 100.

In addition, in this embodiment, sides 11 and 12 appear at the removal opening 122, and thus the area between the third fold F3 and side 11 is doubled, and the area between the fourth fold F4 and side 12 is doubled, making the doubled areas easier to grasp, and thus forming a folded sheet 3 that is easy to remove from the sheet container 100.

In addition, in this embodiment, the sides 11 and 12 of the folding sheet 3 are oriented in the axial direction of the pivot shaft of the hinge portion 124, so that the operation of opening the lid body 123 and the operation of removing the folding sheet 3 after opening the lid body 123 can be performed consecutively in a natural flow. In other words, it is difficult for the operation of changing the orientation of the container body 110 to be sandwiched between the operation of opening the lid body 123 and the operation of removing the folding sheet 3.

-Other embodiments-
It should be noted that the embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention is not interpreted solely by the above-described embodiments, but is defined by the claims. The technical scope of the present invention includes all modifications within the scope and meaning equivalent to the claims.

For example, in the above embodiment, an example was shown in which the lid member 120 was integrally formed from resin, but this is not limiting, and the lid member may be formed from a flexible film. In this case, the lid member may be adhered to a portion of the periphery of the opening of the container body in a manner that makes it difficult to peel off, and adhered to the remaining portion of the periphery of the opening of the container body in a manner that makes it easy to peel off.

In the above embodiment, the folding sheet 3 is stored in the container body 110 so that the surface 32a of the folding sheet 3 is disposed on the lower side. However, the present invention is not limited to this. The folding sheet 3 may be stored in the container body 110 so that the surface 32a of the folding sheet 3 is disposed on the upper side. In other words, the folding sheet 3 may be stored in the container body 110 so that only side 13 of sides 11 to 14 (only the third side of the first to fourth sides in the present invention) appears at the opening of the container body 110 (the removal opening 122 when the lid member 120 is provided).

In addition, in the above embodiment, an example was shown in which the folding sheet 3 is stored in the container body 110 so that the sides 11 and 12 of the folding sheet 3 face the axial direction of the rotation axis of the hinge part 124, but this is not limited thereto, and the folding sheet 3 may be stored in the container body 110 so that the sides 11 and 12 of the folding sheet 3 do not face the axial direction of the rotation axis of the hinge part 124.

The present invention can be used for a method for forming a folded sheet by folding a sheet material, and for a sheet container that contains a folded sheet formed using the method for forming the folded sheet.
