Description

[Technical field]

[0001] The present invention relates to a sheet storage box. [Background technology]

[0002] A sheet storage box is structured so that tissue paper or other sheets are stored in a box (also called a carton) made of cardboard or the like, and are pulled out from an opening on the top of the box. Conventional sheet storage boxes are bulky if disposed of as is after use, so they are designed to be disassembled after use (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5920962 Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to provide a sheet storage box that can be easily disassembled. [Means for solving the problem]

[0005] A first aspect of the present invention is a folding folding apparatus having a top surface with a sheet removal opening, a bottom surface, a pair of side surfaces, and a pair of end surfaces, the end surfaces having a top surface flap extending from an edge of the top surface, a bottom surface flap extending from an edge of the bottom surface, and side surfaces extending from edges of the side surfaces, the bottom surface flap being arranged outside the side surfaces flaps, the top surface flap being arranged outside the bottom surface flap, the top surface flap being joined to the bottom surface flap and the side surfaces flaps, the bottom surface flap and the side surfaces flaps not being joined, and the top surface flap This is a sheet storage box in which a first cutout portion is formed on the bottom side of the wrap, a part of the top flap corresponding to the first cutout portion forms a cutout flap connected to the top flap, the cutout flap has a base end extending from an edge on the bottom side of the top flap to the top side, the cutout flap is formed so as to be able to tilt toward the inside of the side flap along the base end, and when the cutout flap is tilted toward the inside of the side flap, an opening corresponding to the part of the first cutout portion is formed on the end surface.

[0006] In this specification, a sheet storage box refers to a box in which sheets are removably stored. The bottom flap and the side flap are not joined together means that the bottom flap and the side flap are not joined together while the top flap is joined to the bottom flap and the side flap. The inside of the side flap refers to the inside of the sheet storage box. The notched flap is inclined means that the notched flap is inclined toward the inside of the sheet storage box with respect to the end surface.

[0007] In the first aspect, when the notch flaps are inclined inwardly of the side flaps, an opening corresponding to a part of the first notch is formed on the end surface, so that a finger hole for dismantling the sheet storage box can be formed on the end surface. Also, by inserting a finger into this finger hole, the finger can be hooked on the top flap, and by pulling the finger hooked on the top flap toward yourself, the sheet storage box can be easily dismantled.

[0008] In the first aspect, the notch flap is formed to be inclined inward of the side flaps along the base end, so that the notch flap can be easily pushed into the inside of the sheet storage box, and the finger hole can be formed with little force. Also, the top flap is joined to the bottom flap and the side flaps, but the bottom flap and the side flaps are not joined, so that the sheet storage box can be disassembled with little force.

[0009] Furthermore, in the first aspect, the inwardly inclined notched flaps of the side flaps connect to the top flaps, so that no waste such as broken pieces is generated when the sheet storage box is disassembled. Therefore, in the first aspect, the sheet storage box can be easily disposed of after use.

[0010] A second aspect of the present invention is a sheet storage box in which a mountain fold is formed at a base end of the cutout flap. In the second aspect, by providing a mountain fold at the base end of the cutout flap, the cutout flap can be easily folded starting from the base end.

[0011] As a result, in the second aspect, when the cutout flap is pushed into the inside of the seat storage box to form a finger hole for disassembly on the end wall, it is possible to prevent the cutout flap from bending, folding in an unexpected place, or tearing.

[0012] A third aspect of the present invention is a sheet storage box in which the base end of the cutout flap is inclined inwardly toward the first cutout portion from the bottom surface side toward the top surface side. In the third aspect, by inclining the base end of the cutout flap inwardly toward the first cutout portion in this manner, when the cutout flap is inclined inwardly toward the side flap, the contour of the opening (finger hole) formed in the end surface can be enlarged. This makes it easier to insert a finger into the finger hole formed in the end surface.

[0013] A fourth aspect of the present invention is a sheet storage box in which a tearing score line is formed on the top flap, and the notch flap is formed by tearing the tearing score line. In this specification, the tearing score line refers to a score line where cuts and ties (uncut portions between two cuts) are arranged alternately, and when a tie is broken, the adjacent cuts on both sides become continuous cuts.

[0014] In the fourth embodiment, the top flap is formed with a tearing score line, and when the tearing score line is torn, a notch flap is formed, so that, before the sheet storage box is disassembled (before and during use of the sheet storage box), finger holes for disassembly are unlikely to be formed on the end surface unless the tearing score line is torn. Also, after use of the sheet storage box, the sheet storage box can be disassembled by tearing each tearing score line.

[0015] A fifth aspect of the present invention is a sheet storage box in which the tearing score line extends from the bottom edge of the top flap to the top end of the base end. In the fifth aspect, by providing a tearing score line that extends from the bottom edge of the top flap to the top end of the base end, a notch flap that can be inclined inwardly of the side flap along the base end when the tearing score line is torn can be formed.

[0016] A sixth aspect of the present invention is a sheet storage box in which the shape of the tearing score line is a curved line that is convex from the bottom edge of the top flap toward the top. In the sixth aspect, by making the shape of the tearing score line curved, the force for tearing the tearing score line is easily transmitted along the tearing score line. Therefore, in the sixth aspect, the notch flap can be pushed into the inside of the sheet storage box with less force, and finger holes for disassembly can be easily formed.

[0017] In the sixth aspect, the shape of the tearing score line is curved from the bottom edge of the top flap toward the top side, so that the shape of the first cutout portion formed in the top flap after the tearing score line is torn is approximately semicircular. Therefore, in the sixth aspect, the edge of the finger hole for disassembly is arc-shaped, making it easy to insert fingers into the finger hole for disassembly, and reducing the burden on the fingers even if the edge of the finger hole hits the fingers when they are put in the finger hole.

[0018] A seventh aspect of the present invention is a sheet storage box, in which at least a part of the tearing score line has a pair of cuts extending parallel to each other. In this specification, a pair of cuts extending parallel to each other indicates that the cuts constituting the tearing score line are each composed of two cuts arranged parallel to each other.

[0019] In the seventh aspect, at least a part of the tearing score line has a pair of cuts extending parallel to each other, so that the part of the tearing score line composed of the pair of cuts can be easily torn. Therefore, in the seventh aspect, the opening (finger hole) formed on the end surface can be easily formed, and the sheet storage box can be easily disassembled.

[0020] An eighth aspect of the present invention is a sheet storage box in which the edge of the bottom side of the cutout flap curves toward the top side. In the eighth aspect, by curving the edge of the bottom side of the cutout flap toward the top side, the portion of the cutout flap that overlaps with the bottom flap can be reduced. This allows the cutout flap to be pushed into the inside of the sheet storage box with even less force, making it easier to form finger holes for disassembly.

[0021] A ninth aspect of the present invention is a sheet storage box in which a second cutout portion is formed on the top side of the bottom flap by cutting out a portion of the bottom flap, and the second cutout portion is covered by the cutout flap without the cutout flap being inclined inwardly of the side flap.

[0022] In the ninth aspect, the second cutout portion formed on the top side of the bottom flap is covered by the cutout flap connected to the top flap when the cutout flap is not inclined inward of the side flap, so that the portion of the cutout flap that overlaps with the bottom flap can be further reduced. This allows the cutout flap to be pushed into the seat storage box with even less force, making it even easier to form finger holes for disassembly. Effect of the Invention

[0023] According to one aspect of the present invention, the sheet storage box can be easily disassembled. [Brief description of the drawings]

[0046] The material of the box body 10 is not limited, and for example, base paper J made mainly of pulp is used. Here, base paper refers to hard and thick paper that is used as a material for assembling the box body 10. The pulp composition of the base paper can be a known composition for boxes. For example, the pulp blending ratio can be 50 mass% or more, preferably 90 mass% or more, and more preferably 100 mass%. In this embodiment, coated cardboard made of virgin pulp, recycled paper pulp, etc. is used as the base paper.

[0047] The dimensions of the box 10 are not limited and can be determined depending on the amount and dimensions of the sheets S to be stored. The dimensions of the box 10 can be, for example, a length in the longitudinal direction (X direction) of the box 10 of 100 mm to 300 mm, and preferably 150 mm to 280 mm. The width in the lateral direction (Y direction) can be 100 mm to 150 mm, and preferably 100 mm to 130 mm. Furthermore, the height in the height direction (Z direction) can be 30 mm to 150 mm, and preferably 40 mm to 100 mm.

[0048] The basis weight of the box body 10 is not limited, but from the viewpoint of ensuring sufficient strength to withstand use, the basis weight of the base paper is set to 200 g / m 2 More than 500g / m 2 can be less than or equal to 230 g / m 2 More than 450g / m 2 More preferably, it is 270 g / m or less. 2 More than 430g / m 2In this specification, the basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0049] The thickness of the box 10 is not particularly limited, and may be a paper thickness measured under the environment of JIS P 8111 (1998). For example, when the box 10 is made of coated cardboard, the paper thickness of the box 10 may be 0.1 mm or more and 3 mm or less, preferably 0.3 mm or more and 2 mm or less, and more preferably 0.5 mm or more and 1 mm or less.

[0050] In this embodiment, the multiple sheets S contained in the box 10 are configured as a sheet stack SL in which the multiple sheets S are stacked in the height direction (Z direction) (FIG. 4).

[0051] The material of the sheet S is not particularly limited, and may be, for example, a sheet of paper, nonwoven fabric, cloth, or the like, and is preferably a paper sheet (hereinafter referred to as a paper sheet). The pulp composition may be a known composition for paper sheets. For example, the blending ratio of pulp may be 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

[0052] The basis weight of the sheet S is not particularly limited, but may be 5 g / m in the case of paper depending on the number of plies. 2 More than 80g / m 2 For non-woven fabrics, the limit is 20 g / m 2 More than 100g / m 2 The following is preferable. The basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0053] The thickness of the sheet S is not particularly limited, and may be a paper thickness measured under the environment of JIS P 8111 (1998). For example, the thickness of the paper sheet constituting the sheet S may be 50 μm or more and 500 μm or less per two plies, and is preferably 60 μm or more and 330 μm or less.

[0054] The use of the sheet S is not limited to tissue paper, and it can be applied to products such as toilet paper, kitchen paper, paper towels, disposable diapers for babies or for elderly care, sanitary napkins, etc. Sanitary thin paper such as tissue paper also includes sanitary thin paper containing moisturizing ingredients (for example, lotion tissue, etc.). The sheet S can be applied to any of industrial, household, and portable uses.

[0055] The number of plies of the sheet S can be 1 or more, preferably 1, and more preferably 2 (two plies). The shape of the sheet S is not particularly limited, and for example, it is preferable that the shape of the two-ply sheet when folded is rectangular in a plan view.

[0056] The form of the sheet stack SL is not particularly limited, and examples thereof include a sheet stack in which the sheets S are alternately stacked in a folded state (a so-called pop-up type sheet stack SL), a sheet stack in which a plurality of sheets (or a plurality of sets of sheets S) are simply stacked, a sheet stack in which the sheets S are stacked in a folded state, etc. From the viewpoint of pulling out the sheets S one by one or one set at a time, the form of the sheet stack SL is preferably a pop-up type sheet stack SL.

[0057] The dimensions of the sheet laminate SL are, for example, in the case of tissue paper, a length in the longitudinal direction (X direction) of 150 mm to 250 mm, a length in the lateral direction (Y direction) of 60 mm to 130 mm, and a height in the height direction (Z direction) of 20 mm to 110 mm. Such a sheet laminate can be manufactured, for example, by a rotary or multi-stand interfolder.

[0058] The outlet 20 is formed on the top surface 11 of the box 10, and has a shape that allows the sheet (tissue paper) S stored in the box 10 to be taken out from the top surface 11 side. The outlet 20 is formed in the center of the longitudinal direction (X direction) of the top surface 11, and constitutes a substantially rectangular or elliptical opening whose longitudinal direction is along the longitudinal direction (X direction) of the top surface 11.

[0059] The length of the outlet 20 in the longitudinal direction (X direction) and the width in the lateral direction (Y direction) can be appropriately determined based on the size of the sheets S. In this embodiment, the outlet 20 is formed along the longitudinal direction (X direction) at the middle of the lateral direction (Y direction) of the top surface 11 of the sheet storage box 100, but is not limited to this and may have other shapes as long as the sheets S can be taken out.

[0060] Before use, the sheet storage box 100 has a lid 22 formed integrally with the sheet storage box 100 on the top surface 11 via a tearing score line 21. When in use, the lid 22 is torn off along the tearing score line 21 to form an outlet 20 on the top surface 11. This allows the sheets S in the storage space to be taken out upward from the outlet 20. In this embodiment, the tearing score line 21 indicates a cut line such as a perforation along which the lid 22 is torn off when in use (FIG. 1).

[0061] In addition, at the outlet 20 on the top surface 11, a resin film (so-called window film) 30 having a slit 31 in the longitudinal direction (X direction) is provided so as to cover the outlet 20 from the back surface of the top surface 11 (the inside of the box body 10 of the sheet storage box 100).

[0062] The resin film 30 is fixed to the back surface of the top surface 11 by an adhesive or the like applied around the outlet 20. The sheet S is taken out through a slit 31 in the resin film 30. The material of the resin film 30 may be, but is not limited to, polyethylene or polypropylene.

[0063] In this embodiment, a cutout portion 40 is formed by cutting out a part of the top flap 151 on the bottom surface 12 side of the top flap 151. Also, a cutout portion 70 is formed by cutting out a part of the top flap 161 on the bottom surface 12 side of the top flap 161. The cutout portions 40 and 70 are examples of first cutout portions in the sheet storage box of this embodiment.

[0064] A part of the top surface flap 151 corresponding to the cutout portion 40 constitutes a cutout flap 155 connected to the top surface flap 151. Moreover, a part of the top surface flap 161 corresponding to the cutout portion 70 constitutes a cutout flap 165 connected to the top surface flap 161 (FIGS. 2 to 4).

[0065] The cutout flap 155 has a base end 42 extending toward the top surface 11 from an edge 151A on the bottom surface 12 side of the top surface flap 151. The cutout flap 165 has a base end 72 extending toward the top surface 11 from an edge 161A on the bottom surface 12 side of the top surface flap 161 (FIGS. 2 to 4).

[0066] The notched flap 155 is formed so as to be inclined inward of the side flaps 153, 154 along the base end 42. The notched flap 165 is formed so as to be inclined inward of the side flaps 163, 164 along the base end 72. Here, the inside of the side flaps 153, 154, 163, 164 refers to the inside of the box body 10 of the sheet storage box 100.

[0067] In this embodiment, the cutout flap 155 can be inclined toward the inside of the sheet storage box 100 (box body 10) with respect to the end surface 15. Also, the cutout flap 165 can be inclined toward the inside of the sheet storage box 100 (box body 10) with respect to the end surface 16.

[0068] In the sheet storage box 100 of this embodiment, an opening OP corresponding to a part of the notch 40 is formed in the end face 15 with the notch flap 155 of the end face 15 inclined toward the inside of the side flaps 153, 154. Also, an opening OP corresponding to a part of the notch 70 is formed in the end face 16 with the notch flap 165 of the end face 16 inclined toward the inside of the side flaps 163, 164.

[0069] In the sheet storage box 100 of this embodiment, a mountain fold F extending from the end 42A to the end 42B is formed at the base end 42 of the notched flap 155. Also, a mountain fold F extending from the end 72A to the end 72B is formed at the base end 72 of the notched flap 165.

[0070] In the sheet storage box 100 of this embodiment, on the end surface 15, the base end 42 of the cutout flap 155 is inclined toward the inside of the cutout portion 40 from the bottom surface 12 toward the top surface 11 (FIGS. 2 to 5). Also, on the end surface 16, the base end 72 of the cutout flap 165 is inclined toward the inside of the cutout portion 70 from the bottom surface 12 toward the top surface 11 (FIGS. 2 to 5).

[0071] In the sheet storage box 100 of this embodiment, the top flap 151 is formed with a tear-open cut line 41. Also, the top flap 161 is formed with a tear-open cut line 71. Then, the notch flap 155 is formed by tearing the tear-open cut line 41. Also, the notch flap 165 is formed by tearing the tear-open cut line 71.

[0072] Here, the tearing cut lines 41, 71 are perforations in which cuts C and ties T (the uncut portions between two cuts C) are arranged alternately, and when a tie T is broken, the adjacent cuts C on both sides become continuous cuts (Figure 5).

[0073] In addition, the length of each cut C in the tearing score lines 41, 71 can be 0.3 mm to 40 mm, preferably 0.5 mm to 35 mm, and more preferably 1 mm to 30 mm. Also, the length of each tie T can be 0.3 mm to 2.5 mm, preferably 0.5 mm to 1.5 mm, and more preferably 0.8 mm to 1.2 mm.

[0074] In the sheet storage box 100 of this embodiment, the tearing score line 41 extends from the edge 151A on the bottom surface 12 side of the top flap 151 toward the end 42B on the top surface 11 side of the base end 42. In addition, the tearing score line 71 extends from the edge 161A on the bottom surface 12 side of the top flap 161 toward the end 72B on the top surface 11 side of the base end 72.

[0075] In the sheet storage box 100 of this embodiment, the shape of the tearing score line 41 is a curved shape (arcuate shape) that is convex from the edge 151A on the bottom surface 12 side of the top flap 151 toward the top surface 11. Also, the shape of the tearing score line 71 is a curved shape (arcuate shape) that is convex from the edge 161A on the bottom surface 12 side of the top flap 161 toward the top surface 11.

[0076] In the sheet storage box 100 of this embodiment, in the top flap 151 of the end surface 15, an edge 155A of the notched flap 155 on the bottom surface 12 side is curved toward the top surface 11. In addition, in the top flap 161 of the end surface 16, an edge 165A of the notched flap 165 on the bottom surface 12 side is curved toward the top surface 11 (FIGS. 1 to 5).

[0077] Specifically, edge 155A of cutout flap 155 on the bottom surface 12 side forms curved portion 50 that is convex from bottom surface 12 side toward top surface 11 side. Also, edge 165A of cutout flap 165 on the bottom surface 12 side forms curved portion 80 that is convex from bottom surface 12 side toward top surface 11 side (FIGS. 1 to 5).

[0078] In this embodiment, the shape of the curved portions 50, 80 is an arc shape that is convex from the top surface 11 side toward the bottom surface 12 side, but is not limited to this shape. The shape of the curved portions 50, 80 may be, for example, a rectangular shape, a trapezoidal shape that is convex from the top surface 11 side toward the bottom surface 12 side, or the like. The shapes of the curved portions 50, 80 may be different from each other.

[0079] In addition, on the end surface 15, the tearing score line 41 is arranged so that the shortest distance D2 between the end 41A of the tearing score line 41 on the top surface 11 side and the edge 11A of the top surface 11 is longer than the shortest distance D1 between the end 41A of the tearing score line 41 on the top surface 11 side and the curved portion 50 of the top surface flap 151 (FIG. 4). Also, on the end surface 16, the tearing score line 71 is arranged so that the shortest distance between the end of the tearing score line 71 on the top surface 11 side and the edge 11A of the top surface 11 is longer than the shortest distance between the end of the tearing score line 71 on the top surface 11 side and the curved portion 80 of the top surface flap 161 (FIGS. 1 and 2).

[0080] In the sheet storage box 100 of this embodiment, a cutout portion 60 is formed by cutting out a part of the bottom flap 152 on the end surface 15 of the bottom flap 152 on the top surface 11 side of the bottom flap 152. The cutout portion 60 is covered by the cutout flap 155 without being inclined inward of the side flaps 153 and 154.

[0081] In this embodiment, the shape of the cutout 60 is rectangular, but is not limited to this shape. The shape of the cutout 60 may be, for example, an arc shape or a trapezoid shape that is convex from the top surface 11 side to the bottom surface 12 side.

[0082] Also, on the end face 16, a cutout portion 90 is formed by cutting out a part of the bottom flap 162 on the top face 11 side of the bottom flap 162. Then, this cutout portion 90 is covered by the cutout flap 165 without the cutout flap 165 being inclined inward of the side flaps 163, 164.

[0083] In this embodiment, the shape of the cutouts 60 and 90 is rectangular, but is not limited to this shape. The shape of the cutouts 60 and 90 may be, for example, an arc shape or a trapezoid shape that is convex from the top surface 11 side to the bottom surface 12 side. The shapes of the cutouts 60 and 90 may be different from each other.

[0084] Here, the state in which the notch flap 155 is not inclined inwardly of the side flaps 153, 154 refers to the state before the tearing cut line 41 of the top flap 151 is torn at the end surface 15. Also, the state in which the notch flap 165 is not inclined inwardly of the side flaps 163, 164 refers to the state before the tearing cut line 71 of the top flap 161 is torn at the end surface 16. The notches 60, 90 are examples of second notches in the sheet storage box of this embodiment.

[0085] In addition, in the end face 15, the curved portion 50 of the top flap 151 and the notch 60 of the bottom flap 152 are formed so that the shortest distance D3 between the edge 11A of the top face 11 and the curved portion 50 of the top flap 151 is longer than the shortest distance D4 between the notch 60 of the bottom flap 152 and the edge 12A of the bottom face 12 (FIG. 4). In addition, in the end face 16, the curved portion 80 of the top flap 161 and the notch 90 of the bottom flap 162 are formed so that the shortest distance between the edge 11A of the top face 11 and the curved portion 80 of the top flap 161 is longer than the shortest distance between the notch 90 of the bottom flap 162 and the edge 12A of the bottom face 12 (FIGS. 1 and 2).

[0086] Also, on the end surface 15, the curved portion 50 of the top surface flap 151 and the cutout portion 60 of the bottom surface flap 152 are formed so that the width L1 of the curved portion 50 of the top surface flap 151 in the short direction (Y direction) is longer than the width L3 of the cutout portion 60 of the bottom surface flap 152 (FIG. 4). Also, on the end surface 16, the curved portion 80 of the top surface flap 161 and the cutout portion 90 of the bottom surface flap 162 are formed so that the width of the curved portion 80 of the top surface flap 161 in the short direction (Y direction) is longer than the width of the cutout portion 90 of the bottom surface flap 162 (FIGS. 1 and 2).

[0087] Also, on the end face 15, the width L3 of the notch 60 of the bottom flap 152 is formed to be shorter than the distance L2 between the edge 153A of the side flap 153 and the edge 154A of the side flap 154 ​​(FIG. 4). Also, on the end face 16, the width of the notch 90 of the bottom flap 162 is formed to be shorter than the distance between the edge 163A of the side flap 163 and the edge 164A of the side flap 164 (FIGS. 1 and 2).

[0088] The effects of the first embodiment will be described below. In the sheet storage box 100 of the first embodiment, as described above, with the notch flap 155 inclined toward the inside of the side flaps 153 and 154, an opening OP corresponding to a part of the notch 40 (first notch) is formed in the end surface 15, so that a finger hole for disassembling the sheet storage box 100 can be formed in the end surface 15.

[0089] In addition, with the cutout flap 165 inclined inwardly of the side flaps 163, 164, an opening OP corresponding to a part of the cutout portion 70 (first cutout portion) is formed in the end surface 16, so that a finger hole for dismantling the sheet storage box 100 can be formed in the end surface 16 (Figures 1 and 6).

[0090] Furthermore, by inserting a finger P into a finger hole formed in the end face 15, the finger P can be hooked on the top surface flap 151, and by pulling the finger P hooked on the top surface flap 151 toward yourself, the sheet storage box 100 can be easily dismantled. Furthermore, by inserting a finger P into a finger hole formed in the end face 16, the finger P can be hooked on the top surface flap 161, and by pulling the finger P hooked on the top surface flap 161 toward yourself, the sheet storage box 100 can be easily dismantled (FIGS. 6 to 8).

[0091] Also, on end surface 15, notch flap 155 is formed so as to be inclined inward of side flaps 153, 154 along base end 42, so that notch flap 155 can be easily pushed into the inside of sheet storage box 100 (box body 10), and finger holes for dismantling can be formed in end surface 15 with little force. Also, on end surface 16, notch flap 165 is formed so as to be inclined inward of side flaps 163, 164 along base end 72, so that notch flap 165 can be easily pushed into the inside of sheet storage box 100 (box body 10), and finger holes for dismantling can be formed in end surface 16 with little force (FIGS. 1 and 6).

[0092] Moreover, at the end surface 15, the top surface flap 151 is joined to the bottom surface flap 152 and the side surface flaps 153, 154, and the bottom surface flap 152 and the side surface flaps 153, 154 are not joined, so that the sheet storage box 100 (box body 10) can be dismantled with less force. At the end surface 16, the top surface flap 161 is joined to the bottom surface flap 162 and the side surface flaps 163, 164, and the bottom surface flap 162 and the side surface flaps 163, 164 are not joined, so that the sheet storage box 100 (box body 10) can be dismantled with less force (FIGS. 6 to 8).

[0093] As described above, by protruding the portions of the side flaps 153, 154 on the end face 15 that are joined to the top flap 151 toward the top flap 151, the joining surface (not shown) of the bottom flap 152 to the top flap 151 and the joining surfaces (not shown) of the side flaps 153, 154 to the top flap 151 can be made flush.

[0094] In addition, by protruding the portions of the side flaps 163, 164 that are joined to the top flap 161 on the end face 16 toward the top flap 161, the joining surface (not shown) of the bottom flap 162 to the top flap 161 and the joining surfaces (not shown) of the side flaps 163, 164 to the top flap 161 can be made flush.

[0095] This allows the joining distance (not shown) between the top surface flap 151 and the side surface flaps 153, 154 to be shortened on the end surface 15, thereby reducing the amount of adhesive required to join the top surface flap 151 and the side surface flaps 153, 154. Also, since the amount of adhesive required to join the top surface flap 151 and the side surface flaps 153, 154 is reduced, the joining between the top surface flap 151 and the side surface flaps 153, 154 becomes easier to undo, so that the sheet storage box 100 (box body 10) can be dismantled with less force (see FIGS. 6 to 8).

[0096] Also, since the joining distance (not shown) between the top flap 161 and the side flaps 163, 164 can be shortened on the end surface 16, it is possible to reduce the amount of adhesive required to join the top flap 161 and the side flaps 163, 164. Also, since the amount of adhesive required to join the top flap 161 and the side flaps 163, 164 is reduced in this way, the joining between the top flap 161 and the side flaps 163, 164 becomes easier to release, so that the sheet storage box 100 can be dismantled with less force (FIGS. 6 and 7).

[0097] Furthermore, on the end surface 15, the inwardly inclined notched flaps 155 of the side flaps 153, 154 are connected to the top surface flap 151, so that no waste such as broken pieces is generated when the sheet storage box 100 (box body 10) is dismantled. Also, on the end surface 16, the inwardly inclined notched flaps 165 of the side flaps 163, 164 are connected to the top surface flap 161, so that no waste such as broken pieces is generated when the sheet storage box 100 (box body 10) is dismantled. Therefore, in this embodiment, the sheet storage box 100 can be easily disposed of after use (FIGS. 7 and 8).

[0098] In this embodiment, as described above, by providing a mountain fold F at the base end 42 of the cutout flap 155 on the end surface 15, the cutout flap 155 can be easily bent starting from the base end 42. This makes it possible to prevent the cutout flap 155 from bending, bending at an unexpected part, or tearing when the cutout flap 155 is pushed into the inside of the sheet storage box 100 (box body 10) and a finger hole for disassembly is formed (FIGS. 2, 3, and 8).

[0099] Also, by providing a mountain fold F at the base end 72 of the cutout flap 165 on the end surface 16, the cutout flap 165 can be easily bent starting from the base end 72. This makes it possible to prevent the cutout flap 165 from bending, bending at an unexpected part, or tearing when the cutout flap 165 is pushed into the inside of the sheet storage box 100 (box body 10) on the end surface 16 to form a finger hole for disassembly (FIGS. 1, 2, 6, and 7).

[0100] In this embodiment, as described above, the base end 42 of the cutout flap 155 is disposed on the end face 15 so as to be inclined toward the inside of the cutout portion 40 from the bottom face 12 toward the top face 11, so that when the cutout flap 155 is inclined toward the inside of the side flap, the contour of the opening (finger hole) formed on the end face 15 can be enlarged. This makes it easier to insert a finger into the finger hole formed on the end face 15 (FIGS. 2 to 5, 8).

[0101] Furthermore, by arranging the base end 72 of the cutout flap 165 on the end face 16 so as to be inclined toward the inside of the cutout portion 70 from the bottom face 12 toward the top face 11, it is possible to enlarge the contour of the opening (finger hole) formed on the end face 16 when the cutout flap 165 is inclined toward the inside of the side flap. This makes it easier to insert a finger into the finger hole formed on the end face 16 (Figs. 1, 2, 6, and 7).

[0102] In this embodiment, as described above, the tearing score lines 41 are formed on the top surface flaps 151 of the end surface 15, and when the tearing score lines 41 are torn, the notch flaps 155 are formed. Therefore, before the sheet storage box 100 (box body 10) is disassembled (before and during use of the sheet storage box 100), finger holes for disassembly are unlikely to be formed on the end surface 15 unless the tearing score lines 41 are torn (FIGS. 2 to 4). After use of the sheet storage box 100, the sheet storage box 100 (box body 10) can be disassembled by tearing each tearing score line 41 (see FIG. 6 to FIG. 8).

[0103] Also, the top flap 161 of the end face 16 is formed with a tearing cut line 71, and when the tearing cut line 71 is torn, a notch flap 165 is formed, so that, before the sheet storage box 100 (box body 10) is disassembled (before and during use of the sheet storage box 100), finger holes for disassembly are unlikely to be formed on the end face 16 unless the tearing cut line 71 is torn (FIGS. 1 and 2). Also, after use of the sheet storage box 100, the sheet storage box 100 (box body 10) can be disassembled by tearing each tearing cut line 71 (FIGS. 6 and 7).

[0104] In this embodiment, as described above, the end face 15 has a cut line 41 for splitting that extends from the edge 151A of the top surface flap 151 on the bottom surface 12 side toward the end 42B of the base end 42 on the top surface 11 side. This allows the end face 15 to form a notch flap 155 that can be inclined inwardly of the side surface flaps 153, 154 along the base end 42 when the cut line 41 for splitting is split (FIGS. 2 to 5).

[0105] Also, a cut line 71 for cleaving is provided on the end face 16, which extends from the edge 161A of the top surface flap 161 on the bottom surface 12 side toward the end 72B of the base end 72 on the top surface 11 side. As a result, when the cut line 71 for cleaving is cleaved on the end face 16, a notch flap 165 can be formed that can be inclined inward of the side surface flaps 163, 164 along the base end 72 (FIGS. 1, 2, 3 to 5).

[0106] In this embodiment, as described above, by making the shape of the tearing score line 41 curved on the end surface 15, the force for tearing the tearing score line 41 is easily transmitted along the tearing score line 41. Therefore, on the end surface 15, the notched flap 155 can be pushed into the inside of the sheet storage box 100 (box body 10) with little force, and finger holes for disassembly can be easily formed (FIGS. 2 to 5 and 8).

[0107] Furthermore, by making the shape of the tearing cut line 71 curved on the end surface 16, the force for tearing the tearing cut line 71 is easily transmitted along the tearing cut line 71. Therefore, on the end surface 16, the cutout flap 165 can be pushed into the inside of the sheet storage box 100 (box body 10) with little force, and finger holes for disassembly can be easily formed (FIGS. 1, 2, 6, and 7).

[0108] Also, on the end surface 15, the shape of the tearing cut line 41 is curved from the edge 151A on the bottom surface 12 side of the top surface flap 151 toward the top surface 11 side, so that the shape of the notch 40 (first notch) formed in the top surface flap 151 after the tearing cut line 41 is torn is approximately semicircular. Therefore, on the end surface 15, the edge of the finger hole for disassembly (edge ​​40A of the opening OP corresponding to a part of the notch 40) is arc-shaped, making it easy to insert fingers into the finger hole for disassembly, and reducing the burden on the fingers even if the edge 40A of the finger hole hits the finger when the finger is put in the finger hole (FIGS. 2 to 5, 8).

[0109] Also, on the end surface 16, the shape of the tearing cut line 71 is curved from the edge 161A on the bottom surface 12 side of the top surface flap 161 toward the top surface 11 side, so that the shape of the notch 70 (first notch) formed in the top surface flap 161 after the tearing cut line 71 is torn is approximately semicircular. Therefore, on the end surface 16, the edge of the finger hole for disassembly (edge ​​70A of the opening OP corresponding to a part of the notch 70) is arc-shaped, making it easy to insert fingers into the finger hole for disassembly, and reducing the burden on the fingers even if the edge of the finger hole (edge ​​70A of the opening OP) hits the finger when the finger is put in the finger hole (Figs. 1, 2, 6, 7).

[0110] In this embodiment, as described above, the edge 155A of the cutout flap 155 on the bottom surface 12 side is curved toward the top surface 11 on the end surface 15, thereby making it possible to reduce the portion of the cutout flap 155 that overlaps with the bottom surface flap 152. This allows the cutout flap 155 to be pushed into the sheet storage box 100 (box body 10) with even less force on the end surface 15, making it easier to form finger holes for disassembly (FIGS. 2 to 5 and 8).

[0111] Also, on the end surface 16, the edge 165A of the cutout flap 165 on the bottom surface 12 side is curved toward the top surface 11, thereby making it possible to reduce the portion of the cutout flap 165 that overlaps with the bottom surface flap 162. As a result, on the end surface 16, the cutout flap 165 can be pushed into the sheet storage box 100 (box body 10) with even less force, making it easier to form finger holes for disassembly (FIGS. 1, 2, 6, and 7).

[0112] In this embodiment, as described above, on the end surface 15, when the cutout flap 155 is not inclined inwardly toward the side flaps 153, 154, the cutout portion 60 (second cutout portion) formed on the top surface 11 side of the bottom flap 152 is covered by the cutout flap 155 connected to the top flap 151, thereby making it possible to further reduce the portion of the cutout flap 155 that overlaps with the bottom flap 152.

[0113] Specifically, as shown in Fig. 8, the distance D5 between the edge 40A of the opening OP corresponding to a part of the cutout 40 and the edge 60A of the cutout 60 (second cutout) on the bottom surface 12 side can be increased. This allows the cutout flap 155 to be pushed into the sheet storage box 100 (box body 10) with even less force on the end surface 15, making it even easier to form finger holes for disassembly (Figs. 2 to 5 and 8).

[0114] In this embodiment, as described above, on the end surface 16, the cutout flap 165 is not inclined toward the inside of the side flaps 163 and 164, and the cutout portion 90 (second cutout portion) formed on the top surface 11 side of the bottom flap 162 is covered by the cutout flap 165 connected to the top surface flap 161, thereby making it possible to further reduce the portion of the cutout flap 165 that overlaps with the bottom surface flap 162. As a result, on the end surface 16, as with the end surface 15, the cutout flap 165 can be pushed into the inside of the sheet storage box 100 (box body 10) with even less force, making it even easier to form finger holes for disassembly (FIGS. 1, 2, 6, and 7).

[0115] 9 is an enlarged view of the cutout flap and its surroundings in the sheet storage box of the second embodiment. In the sheet storage box according to the second embodiment, at least a part of the tearing score line 41 has a pair of cuts extending parallel to each other on the end surface 15. In this embodiment, the pair of cuts extending parallel to each other are formed by two cuts C1 and C2 arranged parallel to each other on the edge 41B of the tearing score line 41 on the top surface 11 side (FIG. 9).

[0116] In addition, at least a part of the splitting score line 71 has a pair of cuts extending parallel to each other on the end surface 16. In this embodiment, the pair of cuts extending parallel to each other are configured as two cuts arranged parallel to each other, each of which constitutes an edge of the splitting score line 71 on the top surface 11 side (not shown).

[0117] In the second embodiment, at least a part of the tearing score line 41 has a pair of cuts C1, C2 extending parallel to each other on the end surface 15, so that a part of the tearing score line 41 formed by the pair of cuts C1, C2 can be easily torn. Therefore, in this embodiment, it becomes easy to form an opening (finger hole) on the end surface 15, and it becomes easy to disassemble the sheet storage box (FIG. 9).

[0118] In addition, at least a part of the tearing score line 71 has a pair of cuts extending parallel to each other on the end surface 16, so that the part of the tearing score line 71 composed of the pair of cuts can be easily torn. Therefore, in this embodiment, it becomes easy to form the opening (finger hole) on the end surface 16, and the sheet storage box can be easily disassembled.

[0119] Although an embodiment of the present invention has been described above, the present invention is not limited to a specific embodiment, and various modifications and changes are possible within the scope of the invention described in the claims. [Explanation of symbols]
