Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional technique, in order to prevent the storage box with a base plate from losing its shape, complicated operations such as partially pasting were required.

[0005] Therefore, an object of the present invention is to be able to create a storage box with a base plate from a single sheet with simple operations.

Means for Solving the Problems

[0006] The sheet according to the present invention is a single sheet that can be folded to create a storage box with a base plate, and has the following configuration (Aspect 1). The sheet comprises a base portion, a box-forming portion, a slit window portion, and a tongue portion. The base portion is the part that becomes the base plate. The box-forming portion is the part that becomes the storage box and is connected to a first edge, which is one of the edges of the base portion. The slit window portion is opened in the base portion so as to be parallel to the first edge. The tongue portion is connected to a second edge, which is an edge of the box-forming portion that is formed parallel to the first edge at a position opposite to the first edge. Then, the sheet is folded along the first edge, using that fold as a fold line, and along at least one fold line provided parallel to the first edge in the box-forming section. Furthermore, the tongue portion is inserted into the slit window portion, thereby forming a storage box with the box-forming section and the first region, which is the area between the slit window portion and the first edge in the base section.

[0007] According to the above embodiment 1, it becomes possible to form a storage box by a simple operation such as folding the sheet along the fold line and then inserting the tongue portion into the slit window portion.

[0008] The sheet according to the above embodiment 1 may have the following configuration (embodiment 2). The sheet further comprises a first claw portion and a first insertion slit. The first claw portion is a claw portion connected to the tip edge of the tongue portion. The first insertion slit is a slit for inserting and locking the first claw portion, and is formed on the same line as the first end edge or within a first region. The sheet is then folded along the second end edge, which is used as a fold line, and the first claw portion is further inserted into the first insertion slit.

[0009] According to the above embodiment 2, the tongue portion can be fixed in close contact with the back surface of the base plate (the surface opposite to the surface on which the storage box is formed) by a simple operation such as inserting the first claw portion into the first insertion slit, and as a result it becomes possible to create a storage box with a base plate that is less prone to losing its shape.

[0010] The sheet according to the above embodiment 2 may have the following configuration (embodiment 3). The first insertion slit is formed in the first region at a position away from both the first edge and the slit window. The first claw portion, when inserted into the first insertion slit, becomes a partition plate that divides the space inside the storage box into two spatial regions.

[0011] According to embodiment 3 described above, the first claw portion can be given not only the function of a component for creating a storage box with a base plate that is resistant to deformation, but also the function of a partition plate.

[0012] A sheet according to any of the above embodiments 1 to 3 may have the following configuration (embodiment 4). The sheet further comprises a cover portion, a second claw portion, and a second insertion slit. The cover portion is connected to the third edge of the base portion, which is formed parallel to the first edge at a position opposite to the first edge of the base portion. The second claw portion is a claw portion connected to the tip edge of the cover portion. The second insertion slit is a slit for inserting and locking the second claw portion, and is formed on the same line as the second edge. The sheet is then folded along the third edge, which is used as a fold line, and the second claw portion is inserted into the second insertion slit.

[0013] According to embodiment 4 described above, the tongue portion can be fixed to the base portion (base plate) so as not to come out of the slit window portion by a simple operation such as inserting the second claw portion into the second insertion slit portion, and as a result it becomes possible to create a storage box with a base plate that is less prone to losing its shape.

[0014] A sheet relating to any of the above embodiments 1 to 4 may have the following configuration (embodiment 5). The box-forming portion has a main body divided into three regions by two fold lines provided parallel to the first edge, and these three regions are designated as the second region, the third region, and the fourth region in order from the one closest to the first edge, and at least one side edge of these three regions is formed to be on the same straight line. The box-forming portion further has a pair of flap portions connected to the side edge of the second region and the side edge of the fourth region, respectively, and a pair of flap extension portions connected to the leading edges of the pair of flap portions, respectively. The side edge of the second region, the side edge of the fourth region, and the leading edges of the pair of flap portions are all fold lines, and after the tongue portion is inserted into the slit window portion, the sheet is folded along these fold lines, causing the pair of flap extension portions to overlap each other inside the storage box.

[0015] According to embodiment 5 described above, by utilizing a pair of overlapping flap extensions within the storage box, it becomes possible to prevent rattling of the stored items in the lateral direction (along the first edge) within the storage box. [Effects of the Invention]

[0016] According to the present invention, a storage box with a base plate can be easily manufactured from a single sheet of material. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0018] [1] Embodiment [1-1] Structure of the storage box with a base plate Figure 1 is a perspective view of a storage box with a base plate (finished form) that can be made from sheet Q according to the embodiment. In this embodiment, the storage box with a base plate comprises a base plate 1 and a rectangular parallelepiped storage box 2 fixed to the base plate 1. The base plate 1 can be provided with holes 11 for hanging it by hooking it onto a display shelf. In addition, information about the items (items to be stored) to be stored in the storage box 2 (such as the name of the items and their characteristics) can be written on the front 10a (the surface on which the storage box 2 is formed) and the back 10b (the surface opposite to the surface on which the storage box 2 is formed).

[0019] [1-2] Sheet structure Figure 2 is an unfolded view of sheet Q according to the embodiment. As shown in this figure, sheet Q is a single continuous sheet, and it is possible to create a storage box with a base plate by simple operations on the sheet (such as folding, inserting, and tucking). Specifically, it is as follows. Note that sheet Q is not limited to paper material, but can also be made of resin material such as plastic, as long as it does not break when folded.

[0020] Sheet Q comprises a base portion 31, a box-forming portion 32, a slit window portion 33, a tongue portion 34, a first claw portion 35A, and a first insertion slit 36A.

[0021] The base portion 31 is the part that becomes the base plate 1. In this embodiment, the base portion 31 is formed in a rectangular shape. Hereinafter, one of the four edges that constitute the outer periphery of the rectangular base portion 31 (the lower edge in Figure 2) will be called the "first edge J1", and the two edges that extend perpendicularly to the first edge J1 will be called the "side edges K1a" and "side edges K1b", respectively. The unfolded view in Figure 2 is an unfolded view of sheet Q when the base portion 31 is viewed from the side that becomes the front surface 10a of the base plate 1, and each dashed line in Figure 2 (excluding the leader lines for adding reference numerals) indicates that it is part of the outer periphery of each part (including the base portion 31) or each region described below, and also indicates that it is a valley fold line.

[0022] A slit window portion 33 is provided in this base portion 31. Specifically, the slit window portion 33 is provided in the base portion 31 so as to be parallel to the first edge J1, in other words, so as to be aligned with the direction of extension of the first edge J1. The area between the slit window portion 33 and the first edge J1 of the base portion 31 (hereinafter referred to as the "first area R1") becomes the back wall 20a (see Figure 1) of the six walls that make up the rectangular storage box 2.

[0023] The box-forming section 32 is the part that becomes the storage box 2. In this embodiment, the box-forming section 32 has a rectangular main body section 320 connected to the base section 31 at the first edge J1. More specifically, the main body section 320 is divided into three regions by two fold lines Lt1 and Lt2 provided parallel to the first edge J1. These three regions are the parts that become the bottom wall 20b, the front wall 20c, and the top wall 20d (see Figure 1) of the six walls that make up the storage box 2. Hereinafter, these three regions will be referred to as "second region R2", "third region R3", and "fourth region R4", in order from the one closest to the first edge J1. Also, of the four edges that make up the outer periphery of each region, the two edges that extend perpendicular to the first edge J1 will both be referred to as "side edges".

[0024] As a result, one side edge K2a, K3a, and K4a of the three regions are formed to be on the same straight line, and furthermore, the other side edge K2b, K3b, and K4b of the three regions are also formed to be on the same straight line. In addition, in this embodiment, one side edge K2a, K3a, and K4a are formed to be on the same straight line as the side edge K1a of the base portion 31, and the other side edge K2b, K3b, and K4b are formed to be on the same straight line as the side edge K1b of the base portion 31. Furthermore, because the main body portion 320 has a rectangular shape, the edge opposite to the first edge J1 of the four edges that constitute the outer periphery of the main body portion 320 (hereinafter referred to as the "second edge J2") is formed to be parallel to the first edge J1.

[0025] Furthermore, in this embodiment, in order that the storage box 2 produced from the box forming section 32 is rectangular parallelepiped, the second region R2 and the fourth region R4 are formed so that their vertical widths Wr2 and Wr4 (widths in the direction perpendicular to the first edge J1) are the same, and the third region R3 is formed so that its vertical width Wr3 is the same as the vertical width Wr1 of the first region R1.

[0026] The box-forming section 32 further includes a pair of flap sections 321A, another pair of flap sections 321B, two rectangular lid sections 322A and 322B, and two tuck sections 323A and 323B. Specifically, the pair of flap sections 321A are connected to one side edge K2a and K4a of the second region R2 and the fourth region R4, respectively, and the other pair of flap sections 321B are connected to the other side edge K2b and K4b of the second region R2 and the fourth region R4, respectively. The two lid sections 322A and 322B are connected to both side edges K3a and K3b of the third region R3, respectively. These two lid sections 322A and 322B form two side walls 20e and 20f (see Figure 1) of the six walls that make up the storage box 2. The two tack portions 323A and 323B are connected to the leading edges MtA and MtB of the two lid portions 322A and 322B, respectively.

[0027] The tongue portion 34 is connected to the main body portion 320 at the second end edge J2. In this embodiment, the tongue portion 34 is rectangular in shape, and its width Wc (width in the direction along the first end edge J1) is configured to be smaller than the length Xs of the slit window portion 33. Furthermore, the tongue portion 34 is configured such that its length Yc (length from the second end edge J2 to the tip edge MtC on the opposite side of the second end edge J2) in the direction perpendicular to the first end edge J1 is the same as the vertical width Wr1 of the first region R1 in the same direction (distance between the slit window portion 33 and the first end edge J1).

[0028] The first claw portion 35A is a claw portion connected to the tip edge MtC of the tongue portion 34 (the edge opposite to the second edge J2). Similar to the tongue portion 34, the first claw portion 35A is configured such that its lateral width Wd (width in the direction along the first edge J1) is smaller than the length Xs of the slit window portion 33.

[0029] The first insertion slit 36A is a slit for inserting and locking the first claw portion 35A, and in this embodiment it is formed on the same line as the first end edge J1.

[0030] [1-3] How to create a storage box with a base plate from a sheet Figures 3(A) to 6(B) are perspective views showing the procedure for creating a storage box with a base plate from sheet Q. In these figures, dashed lines and dotted lines (excluding leader lines for adding symbols) indicate valley fold lines and mountain fold lines, respectively.

[0031] First, the sheet Q is folded along the first edge J1, which serves as the fold line (see Figure 3(A)). Next, the sheet Q is folded along the two fold lines Lt1 and Lt2 provided on the box forming section 32, and then the tongue portion 34 is inserted into the slit window portion 33 (see Figures 3(B) and 4(A)). As a result, the back wall 20a, bottom wall 20b, front wall 20c, and top wall 20d of the six walls (see Figure 1) that make up the rectangular storage box 2 are formed by four regions, from the first region R1 to the fourth region R4.

[0032] Subsequently, the tip edge MtC of the tongue portion 34 is used as a fold line, and the sheet Q is folded along this fold line, thereby orienting the first claw portion 35A downward relative to the tongue portion 34 (see Figure 4(B)). Then, the second end edge J2 is used as a fold line, and the sheet Q is folded along this fold line, and the first claw portion 35A is inserted into the first insertion slit 36A (see Figure 5). This allows the tongue portion 34 to be fixed in close contact with the back surface 10b of the base plate 1 (the surface opposite to the surface where the storage box 2 is formed (front surface 10a)). Thus, it becomes possible to create a storage box 2 on the front surface 10a of the base plate 1 that is resistant to deformation.

[0033] Subsequently, in order to close the openings on both sides of the storage box 2, the sheet Q is folded along the side edges K2a and K2b of the second region R2 and the side edges K4a and K4b of the fourth region R4, using these fold lines as fold lines, thereby covering one opening of the storage box 2 with a pair of flap portions 321A and the other opening of the storage box 2 with a pair of flap portions 321B (see Figure 6(A)).

[0034] Then, using the side edges K3a and K3b of the third region R3 and the leading edges MtA and MtB of the two lid portions 322A and 322B as fold lines, the sheet Q is folded along these fold lines. Furthermore, the two tuck portions 323A and 323B are inserted into the openings on both sides of the storage box 2, respectively, along the first region R1, thereby closing those openings with the two lid portions 322A and 322B (see Figure 6(B)). This forms a rectangular parallelepiped-shaped storage box 2 that is resistant to deformation.

[0035] Thus, with the sheet Q of this embodiment, it is possible to create a storage box with a base plate that is resistant to deformation by simply folding the sheet Q along the fold line, inserting the tongue portion 34 into the slit window portion 33, and further inserting the first claw portion 35A into the first insertion slit 36A.

[0036] [2] Variant [2-1] First variation In the embodiment described above, sheet Q may have the following configuration.

[0037] Figure 7 is an unfolded view of sheet Q according to the first modified example. In this modified example, the first insertion slit 36A is formed within the first region R1 at a position away from both the first edge J1 and the slit window 33. Furthermore, the tongue portion 34 is configured such that the length Yc of the tongue portion 34 in the direction perpendicular to the first edge J1 (length from the second edge J2 to the tip edge MtC) is the same as the distance Zr1 from the slit window 33 to the first insertion slit 36A in the same direction.

[0038] Figure 8(A) is a partial front view showing the main part of the storage box with a base plate (finished form) that can be made from sheet Q according to the first modified example, and Figure 8(B) is an end view of the section cut along line V1-V1 in Figure 8(A). In this modified example, as shown in Figure 8(B), the first claw portion 35A (a claw portion connected to the tip edge MtC of the tongue portion 34) is inserted into the first insertion slit 36A, thereby becoming a partition plate that divides the space Sp inside the storage box 2 into two spatial regions Sp1 and Sp2.

[0039] According to this first modification, the first claw portion 35A can be given not only the function of a component that creates a storage box with a base plate that is resistant to deformation, but also the function of a partition plate. As a result, two items (items to be stored) can be stored in the storage box 2 separated by the first claw portion 35A. Furthermore, by appropriately changing the formation position of the first insertion slit 36A within the first region R1, two spatial regions Sp1 and Sp2 with different volumes can be formed inside the storage box 2.

[0040] [2-2] Second variation In the embodiment described above, sheet Q may have the following configuration. Note that the configuration of the second modified example described below can also be applied to the first modified example described above.

[0041] Figure 9 is an unfolded view of sheet Q according to the second modified example. In this modified example, sheet Q further comprises a cover portion 37, a second claw portion 35B, a second insertion slit 36B, and a pair of wing portions 38.

[0042] The cover portion 37 is a part that covers a portion of the front surface 10a of the base plate 1, and is connected to the edge of the base portion 31 that will become the base plate 1 that is opposite to the first edge J1 (the edge formed parallel to the first edge J1 at a position opposite to the first edge J1; hereinafter this edge will be referred to as the "third edge J3"). In this embodiment, the cover portion 37 is formed in a rectangular shape, and both side edges K7a and K7b are formed to be in the same straight line as both side edges K1a and K1b of the base portion 31, respectively. Furthermore, the cover portion 37 is configured such that the length Yd of the cover portion 37 in the direction perpendicular to the first edge J1 (the length from the third edge J3 to the tip edge MtD opposite to the third edge J3) is the same as the distance Zr2 from the third edge J3 to the slit window portion 33 in the same direction.

[0043] The second claw portion 35B is a claw portion connected to the tip edge MtD of the cover portion 37 (the edge opposite to the third end edge J3).

[0044] The second insertion slit 36B is a slit for inserting and locking the second claw portion 35B, and in this modified example, it is formed on the same line as the second end edge J2.

[0045] The pair of wing portions 38 are used overlapping the front surface 10a of the base plate 1, and are connected to the portion between the third end edge J3 and the slit window portion 33 of both side edges K1a and K1b of the base portion 31.

[0046] Figure 10 is a perspective view showing an intermediate state (corresponding to Figure 5) in the procedure for creating a storage box with a base plate from sheet Q according to the second modified example. Figures 11(A) and 11(B) are perspective views showing the procedure continuing from Figure 10. In this modified example, after inserting the first claw portion 35A into the first insertion slit 36A (see Figure 10), the sheet Q is first folded along the fold lines between the third end edge J3 of both side edges K1a and K1b of the base portion 31 and the slit window portion 33, thereby overlapping the pair of wing portions 38 onto the front surface of the base portion 31 (the surface that becomes the front surface 10a of the base plate 1). Subsequently, using the third edge J3 as a fold line, the sheet Q is folded along this line, thereby overlapping the cover portion 37 with the pair of wing portions 38, and further inserting the second claw portion 35B into the second insertion slit 36B (see Figures 11(A) and 11(B)).

[0047] With this second modification, the tongue portion 34 can be fixed to the base portion 31 (base plate 1) so as not to come out of the slit window portion 33 by a simple operation such as inserting the second claw portion 35B into the second insertion slit 36B. Therefore, the synergistic effect of inserting the first claw portion 35A into the first insertion slit 36A and inserting the second claw portion 35B into the second insertion slit 36B makes it possible to create a storage box with a base plate that is stronger and less prone to deformation.

[0048] Furthermore, according to this modified version, the pair of wing sections 38 can be superimposed on the front surface 10a of the base plate 1, and the cover section 37 can be superimposed on top of them. This makes it possible to store a sheet-like item (an item different from the item stored in the storage box 2) between the base plate 1 and the cover section 37. In addition, since the portion of the front surface 10a of the base plate 1 that is covered by the cover section 37 can be hidden from external view, it becomes possible to write highly confidential information on that portion.

[0049] [2-3] Third variation In the second modified example described above, sheet Q may have the following configuration.

[0050] Figure 12 is an unfolded view of sheet Q according to the third modified example. In this modified example, sheet Q is provided with a second claw portion 35B and a second insertion slit 36B, while the first claw portion 35A and the first insertion slit 36A are omitted. In addition, in this modified example, the tongue portion 34 is configured such that its length Yc is shorter than the vertical width Wr1 of the first region R1 of the base portion 31.

[0051] Figure 13 is a perspective view showing an intermediate state in the procedure for creating a storage box with a base plate from sheet Q according to the third modified example. In this modified example, after inserting the tongue portion 34 into the slit window portion 33, the sheet Q is folded along the second edge J2, which is used as a fold line, so that the tongue portion 34 is aligned with the back surface of the base portion 31 (the surface that becomes the back surface 10b of the base plate 1) (see Figure 13). Then, similar to the fourth modified example, the pair of wing portions 38 are placed on the front surface 10a of the base plate 1, and then the second claw portion 35B is inserted into the second insertion slit 36B (see Figures 11(A) and 11(B)).

[0052] In this third modification, as in the second modification, the tongue portion 34 can be fixed to the base portion 31 (base plate 1) so as not to come out of the slit window portion 33 by a simple operation such as inserting the second claw portion 35B into the second insertion slit 36B. As a result, it becomes possible to create a storage box with a base plate that is less prone to losing its shape.

[0053] [2-4] Fourth variation In the embodiments described above, sheet Q may have the following configuration. Note that the configuration of the fourth modified example described below can also be applied to the first to third modified examples described above.

[0054] Figure 14 is an unfolded view of sheet Q according to the fourth modified example. In sheet Q of this modified example, the box-forming portion 32 further has a pair of flap extensions 324. Specifically, the pair of flap extensions 324 are connected to the leading edge MtE of the pair of flap portions 321A (the edge opposite to the side edges K2a and K4a).

[0055] Figure 15(A) is a partial side view showing the main part of a storage box with a base plate (before closing the lid 322A) that can be made from sheet Q according to the fourth modification, and Figure 15(B) is an end view showing a part of the cut section along line V2-V2 in Figure 15(A). In this modification, before closing one opening of the storage box 2 with the lid 322A (see Figure 15(A)), the side edge K2a of the second region R2, the side edge K4a of the fourth region R4, and the leading edge MtE of the pair of flap portions 321A are all used as fold lines, and sheet Q is folded along these fold lines so that the pair of flap portions 321A are placed over one opening of the storage box 2, and the pair of flap extensions 324 are overlapped with each other inside the storage box 2 (see Figure 15(B)).

[0056] According to this fourth modification, by utilizing a pair of overlapping flap extensions 324 within the storage box 2, it becomes possible to prevent rattling of the items (storage items; shown by a dashed line in Figure 15(B)) in the lateral direction (along the first edge J1) within the storage box 2.

[0057] Furthermore, the pair of flap extensions 324 may be provided not only on one of the pair of flap portions 321A, but also on the tip edge MtE of the other pair of flap portions 321B.

[0058] [2-5] Fifth variation In the sheet Q described above, the main body 320 of the box-forming section 32 is not limited to being divided into three regions by two fold lines provided parallel to the first edge J1, but may be appropriately modified to be divided by at least one fold line provided parallel to the first edge J1. This makes it possible to create storage boxes 2 whose cross-sectional shape (cross-section perpendicular to the first edge J1) is not limited to a rectangle, but can be other shapes such as a triangle or other polygons.

[0059] The above-described embodiments and modifications should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims, rather than by the above-described embodiments and modifications. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the claims. [Explanation of Symbols]
