Description

[Technical Field]

[0001] This invention relates to an attachment for a seat storage box. [Background technology]

[0002] In recent years, with increased awareness of hygiene as a measure to prevent infectious diseases, the use of disposable paper towels and tissues has increased as an alternative to cloth towels used by multiple people for drying hands. Paper towels and similar sheets are stored in boxes (also called cartons) made of cardboard or similar material, and the sheets are pulled out from an opening on the top of the box and used in a flat position (see, for example, Patent Document 1). [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Patent No. 4142238 [Overview of the project] [Problems that the invention aims to solve]

[0004] However, conventional sheet storage boxes are bulky because the sheets are stored in cardboard boxes, which limits where they can be placed, especially in bathrooms or other wet areas or confined spaces.

[0005] The object of the present invention is to provide an attachment for a seat storage box that is less restricted in terms of where the seat storage box can be placed. [Means for solving the problem]

[0006] A first aspect of the present invention is an attachment for a sheet storage box, which is detachably attached to a sheet storage box and used to suspend the sheet storage box, comprising: a plate-shaped base; a first locking portion extending flexibly from one edge of the base and locking to the sheet storage box; and a second locking portion formed between the other edge of the base and the one edge and locking the base to external equipment.

[0007] In the first embodiment, a first locking portion extending from one edge of the base is locked to the sheet storage box, and a second locking portion formed between the other edge and the one edge of the base locks the base to the external equipment, thereby allowing the sheet storage box to be suspended from the external equipment.

[0008] Therefore, by using the attachment for the sheet storage box according to the first embodiment, it can be used not only when placed flat but also when suspended from an external device, thus reducing the limitations on the placement of the sheet storage box. In addition, a sheet storage box suspended from an external device can be used hygienically.

[0009] A second aspect of the present invention is an attachment for a sheet storage box according to the first aspect, wherein the second locking portion extends flexibly from both side edges of the base portion toward the base portion, and has a notch on one of the edges between the second locking portion and the base portion.

[0010] In the second embodiment, the second locking portion extending from both side edges of the base has a notch on one edge between the second locking portion and the base. When the second locking portion is bent relative to the base, the notch of the second locking portion is positioned opposite the direction in which the other edge of the base extends. Therefore, when the external equipment is a bar such as a towel rack, the notch of the second locking portion can be stably locked to the bar, allowing the seat storage box to be installed hygienically even in wet areas such as bathrooms.

[0011] A third aspect of the present invention is an attachment for a sheet storage box according to the first or second aspect, further comprising a third locking portion extending from the base end of the first locking portion on the base side and being locked to the sheet storage box.

[0012] In the third embodiment, the third locking portion extending from the base end of the first locking portion is locked to the seat storage box, thereby allowing the first locking portion and the third locking portion to be locked to two different locations on the seat storage box. As a result, the attachment for the seat storage box can be stably attached to the seat storage box.

[0013] A fourth aspect of the present invention is an attachment for a sheet storage box according to the fourth aspect, wherein when the first locking portion is bent relative to the base portion, a through hole is formed near one end edge of the base portion, corresponding to the third locking portion.

[0014] In the fourth embodiment, before the first locking portion is bent relative to the base, the surface from which the third locking portion extends is flush with the surface of the base. However, after the first locking portion is bent relative to the base, the surface from which the third locking portion extends intersects with the surface of the base. Therefore, in the region where the third locking portion was located before the first locking portion was bent relative to the base, a through hole corresponding to the third locking portion is formed after the first locking portion is bent relative to the base.

[0015] In the fourth aspect, with this configuration, when the first locking portion is bent relative to the base, a through hole is formed near one edge of the base, corresponding to the third locking portion. Therefore, the through hole formed near one edge of the base can constitute a second locking portion that locks the base to external equipment. This allows the second locking portion to be locked to external equipment by using a hook or other component, regardless of whether the external equipment is a bar such as a towel rack.

[0016] A fifth aspect of the present invention is a seat storage box attachment according to any of the first to fourth aspects, wherein the seat storage box attachment is formed by cutting out a part of the seat storage box.

[0017] In the fifth aspect, a part of the sheet storage box is cut out to form the attachment for a sheet storage box, whereby the attachment for a sheet storage box cut out from the sheet storage box can be used only when it is desired to use the sheet storage box in a suspended manner. Therefore, in the fifth aspect, the attachment for a sheet storage box can be prepared according to the environment in which the sheet storage box is installed. Effects of the Invention

[0018] According to one aspect of the present invention, an attachment for a sheet storage box that makes the installation location of the sheet storage box less likely to be restricted can be provided. Brief Description of the Drawings

[0024] The seat storage box attachment 100 shown in Figure 1 is detachably attached to the seat storage box 200 in order to suspend the seat storage box 200.

[0025] The material of attachment 100 is not limited; for example, base paper made primarily from pulp, polypropylene, polyethylene, and other plastics can be used.

[0026] Here, the base paper refers to a stiff, thick paper that serves as the material for maintaining the shape of the attachment 100. The pulp composition of the base paper is not particularly limited; for example, the pulp content can be 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass. In this embodiment, coated cardboard made from virgin pulp, recycled paper pulp, etc., is used as the base paper.

[0027] Furthermore, while there are no restrictions on the basis weight of the base paper, from the perspective of ensuring sufficient strength to withstand the use of Attachment 100, the basis weight of the base paper should be 200 g / m². 2 More than 500g / m 2 The following, preferably 230 g / m² 2 More than 450g / m 2 The following, and more preferably 270 g / m² 2 More than 430g / m 2 The following applies. In this specification, basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0028] The thickness of the base paper is not particularly limited, and the paper thickness measured under the conditions of JIS P 8111 (1998) can be used. For example, if the attachment 100 is made of coated cardboard, the paper thickness of the attachment 100 can 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.

[0029] The form of the sheet storage box 200 to which the attachment 100 is attached is not particularly limited. For example, as shown in Figure 2, the sheet storage box 200 has a box body 10 that can accommodate a plurality of sheets S, and an outlet 20 from which the sheets S can be removed. The box body 10 has a top surface 11, a bottom surface 12, a pair of side surfaces 13, 14, and a pair of end surfaces 15, 16, to which the sheet S outlet 20 is provided.

[0030] The box body 10 is a container in which the sheets S are stored. In this embodiment, as shown in Figure 2, the box body 10 is formed in a substantially rectangular parallelepiped shape. The top surface 11 and the bottom surface 12 face the stacking direction (Z direction) of the sheets S, the side surfaces 13 and 14 face the short side direction (Y direction) of the sheet storage box 200, and the end surfaces 15 and 16 face the long side direction (X direction) of the sheet storage box 200.

The bottom surface 12 faces the top surface 11 in the stacking direction (Z direction) of the sheets S and extends in the longitudinal direction (X direction).

[0032] The pair of side surfaces 13 and 14 face each other in a direction perpendicular to the stacking direction (Z direction) and perpendicular to the longitudinal direction (X direction), and extend in the longitudinal direction (X direction). The pair of end surfaces 15 and 16 face each other in the longitudinal direction (X direction).

[0033] As shown in Figures 3 and 4, the box body 10 has a bonding surface (not shown) attached to the edge 12C of the bottom surface 12, to which adhesive (not shown) is provided. The bonding surface is joined to the edge 13D side of the side surface 13.

[0034] The end face 15 is composed of a top flap 151, a bottom flap 152, a side flap 153, and a side flap 154 ​​(Figure 3). The end face 16 is composed of a top flap 161, a bottom flap 162, a side flap 163, and a side flap 164 (Figure 4).

[0035] Specifically, at the end face 15, the top flap 151 extends from the edge 11A of the top surface 11, and the bottom flap 152 extends from the edge 12A of the bottom surface 12 (Figure 3). Also, at the end face 16, the top flap 161 extends from the edge 11B of the top surface 11, and the bottom flap 162 extends from the edge 12B of the bottom surface 12 (Figure 4).

[0036] Furthermore, at the end face 15, a side flap 153 extends from the edge 13A of the side surface 13, and a side flap 154 ​​extends from the edge 14A of the side surface 14. Also, at the end face 16, a side flap 163 extends from the edge 13B of the side surface 13, and a side flap 164 extends from the edge 14B of the side surface 14.

[0037] Furthermore, folds (not shown) are provided on the edges 11A, 11B, 11C, 11D of the top surface 11, the edges 12A, 12B, 12C, 12D of the bottom surface 12, the edges 13A, 13B, 13C, 13D of the side surface 13, and the edges 14A, 14B, 14C, 14D of the side surface 14.

[0038] At each fold, the sides 13, 14 and top flaps 151, 161 can be folded relative to the top surface 11; the sides 14, the adhesive area, and the bottom flaps 152, 162 can be folded relative to the bottom surface 12; the top surface 11 and side flaps 153, 163 can be folded relative to the side surface 13; and the top surface 11, bottom surface 12, and side flaps 154, 164 can be folded relative to the side surface 14.

[0039] On the end face 15, the top flap 151 is positioned outside the bottom flap 152 and the side flaps 153 and 154, with the bottom flap 152 positioned outside the side flaps 153 and 154. Similarly, on the end face 16, the top flap 161 is positioned outside the bottom flap 162 and the side flaps 163 and 164, with the bottom flap 162 positioned outside the side flaps 163 and 164.

[0040] Furthermore, on the end face 15, a pair of adhesives G1 are provided on the side edges 152B and 152C on the edge 152A side of the bottom flap 152, adhesives G2 are provided on the edge 153C and 154C sides of the side flaps 153 and 154, and adhesives G3 are provided on the edge 153B and 154B sides (Figure 3). Note that only adhesives G3 are required on the side flaps 153 and 154, and adhesives G2 do not need to be provided.

[0041] Furthermore, on the end face 16, a pair of adhesives G3 are provided on the side edges 162B and 162C of the bottom flap 162A, adhesives G2 are provided on the side edges 163C and 164C of the side flaps 163 and 164, and adhesives G3 are provided on the side edges 163B and 164B (Figure 4). Note that only adhesives G3 are required on the side flaps 163 and 164, and adhesives G2 are not required.

[0042] The bottom flap 152 is joined to the side flaps 153 and 154 via adhesive G2. In this state, when the top flap 151 is joined to the side flaps 153 and 154 via adhesive G3 and to the bottom flap 152 via adhesive G1, the end face 15 is formed (Figure 3).

[0043] The bottom flap 162 is joined to the side flaps 163 and 164 via adhesive G2. In this state, when the top flap 161 is joined to the side flaps 163 and 164 via adhesive G3 and to the bottom flap 162 via adhesive G1, the end face 16 is formed (Figure 4).

[0044] Furthermore, it is preferable that the adhesives G2 and G3 are applied to the top flap 151 and bottom flap 152 of the end face 15 on the side flaps 153 and 154, respectively. Similarly, it is preferable that the adhesives G2 and G3 are applied to the top flap 161 and bottom flap 162 of the end face 16 on the side flaps 163 and 164, respectively.

[0045] Furthermore, the portions of the side flaps 153 and 154 that are joined to the top flap 151 (the portions to which adhesive is applied) may protrude toward the top flap 151 when joined to the top flap 151. Similarly, the portions of the side flaps 163 and 164 that are joined to the top flap 161 (the portions to which adhesive is applied) may protrude toward the top flap 161 when joined to the top flap 161.

[0046] Furthermore, on the end face 15, the entire top flap 151 is exposed, the portion of the bottom flap 152 that overlaps with the top flap 151 is concealed, and the portion of the bottom flap 152 that does not overlap with the top flap 151 is exposed. In addition, the side flaps 153 and 154 are concealed inside the top flap 151 and bottom flap 152 (Figures 3 and 4).

[0047] Furthermore, on the end face 16, the entire top flap 161 is exposed, the portion of the bottom flap 162 that overlaps with the top flap 161 is concealed, and the portion of the bottom flap 162 that does not overlap with the top flap 161 is exposed. In addition, the side flaps 163 and 164 are concealed inside the top flap 161 and bottom flap 162 (Figures 3 and 4).

[0048] Furthermore, on the end face 15, the side flaps 153 and 154 have edges 153A and 154A facing each other in the short direction (Y direction), edges 153B and 154B positioned on the top surface 11 side, and edges 153C and 154C positioned on the bottom surface 12 side. Similarly, on the end face 16, the side flaps 163 and 164 have edges 163A and 164A facing each other in the short direction (Y direction), edges 163B and 164B positioned on the top surface 11 side, and edges 163C and 164C positioned on the bottom surface 12 side (Figure 3).

[0049] As a result, in the sheet storage box 200, a gap of length K in the short direction (Y direction) is formed between the top flap 151, bottom flap 152, and side flaps 153 and 154 in the thickness direction (X direction) of the end face 15 (Figure 3). Also, a gap of length K in the short direction (Y direction) is formed between the top flap 161, bottom flap 162, and side flaps 163 and 164 in the thickness direction (X direction) of the end face 16 (Figure 4).

[0050] The material of the box body 10 is not limited; for example, base paper made primarily from pulp can be used. The base paper used for the box body 10 can be the same as the base paper used for the attachment 100.

[0051] The dimensions of the box body 10 are not limited, and can be determined depending on the amount, dimensions and the like of the sheets S to be stored. For example, the length of the box body 10 in the longitudinal direction (X direction) can be 100 mm or more and 300 mm or less, preferably 150 mm or more and 280 mm or less.

[0052] In addition, the width of the box body 10 in the transverse direction (Y direction) can be 100 mm or more and 150 mm or less, preferably 100 mm or more and 130 mm or less. Furthermore, the height of the box body 10 in the height direction (Z direction) can be 30 mm or more and 150 mm or less, preferably 40 mm or more and 100 mm or less.

[0053] In this embodiment, the plurality of sheets S accommodated in the box body 10 are configured as a sheet laminate SL in which the plurality of sheets S are laminated in the lamination direction (Z direction) (Fig. 2).

[0054] The material of the sheet S is not particularly limited. For example, sheets such as paper, non-woven fabric or cloth can be used, and paper sheets (hereinafter referred to as paper sheets) are preferable. A known pulp composition for paper sheets can be used for the pulp composition. The blending ratio of pulp can be, for example, 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

[0055] In addition, the basis weight of the sheet S is not particularly limited, but depending on the number of plies, for paper, it is 5 g / m 2 or more and 80 g / m 2 or less, and for non-woven fabric, it is 20 g / m 2 or more and 100 g / m 2 or less is preferable. The basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0056] In addition, the thickness of the sheet S is not particularly limited, and the paper thickness measured under the environment specified in JIS P 8111 (1998) can be adopted. For example, the paper thickness of the paper sheet constituting the sheet S can be 50 µm or more and 500 µm or less per 1 ply (per 2 plies in the case of 2 plies), and preferably 60 µm or more and 330 µm or less.

[0057] The form of Sheet S is not particularly limited and can be applied to items such as paper towels, tissue paper, toilet paper, kitchen paper, baby or adult diapers, and sanitary napkins. Note that sanitary tissue paper such as paper towels and tissue paper also includes sanitary tissue paper containing moisturizing ingredients (e.g., lotion tissue). Furthermore, Sheet S can be used for industrial, household, or portable purposes.

[0058] The number of plies in sheet S can be one or more, preferably one ply or two plies (two layers). The shape of sheet S is not particularly limited, but for example, it is preferable that the shape of a one-ply or two-ply sheet when folded is rectangular in plan view.

[0059] The form of the sheet laminate SL is not particularly limited, and examples include a laminate in which each sheet S is folded and stacked alternately (a so-called pop-up type sheet laminate SL), a laminate in which multiple sheets (or multiple sets) of sheets S are simply stacked, or a laminate in which each sheet S is folded and stacked. However, from the viewpoint of pulling out one sheet or one set of sheets S at a time, a pop-up type sheet laminate SL is preferred.

[0060] The dimensions of the sheet laminate SL are, for example, in the case of paper towels, 150 mm to 250 mm in the longitudinal direction (X direction), 60 mm to 130 mm in the transverse direction (Y direction), and 20 mm to 110 mm in height in the stacking direction (Z direction). Such sheet laminates can be manufactured, for example, by a rotary type or multi-stand type interfolder.

[0061] The dispensing opening 20 is formed on the top surface 11 of the box body 10, and is shaped so that the sheets (tissue paper) S contained in the box body 10 can be removed from the top surface 11 side. The dispensing opening 20 is formed in the center of the longitudinal direction (X direction) of the top surface 11, and forms a roughly rectangular or elliptical opening in which the longitudinal direction (X direction) of the top surface 11 is aligned with the longitudinal direction of the dispensing opening 20 (Figure 2).

[0062] The length in the longitudinal direction (X direction) and the width in the transverse direction (Y direction) of the dispensing opening 20 can be appropriately determined based on the size of the sheet S, etc. In this embodiment, the dispensing opening 20 is formed in a substantially elliptical shape along the longitudinal direction (X direction) in the middle of the transverse direction (Y direction) of the top surface 11 of the sheet storage box 200, but it is not limited to this, and other positions on the top surface 11 and other shapes may be used as long as the sheet S can be removed.

[0063] Before use, the sheet storage box 200 has a lid 22 integrally formed with the top surface 11 via a tearing line 21. When in use, the lid 22 is separated along the tearing line 21, creating an opening 20 on the top surface 11. This allows the sheets S inside the box 10 to be removed through the opening 20 (see Figure 2).

[0064] In this embodiment, the tearing line 21 indicates a perforation or other cutting line used to separate the lid 22 when using the sheet storage box 200 (Figure 2). The tearing line 21 is a perforation in which cuts and ties (uncut portions between two cuts) are arranged alternately, and when a tie breaks, the adjacent cuts become continuous cuts.

[0065] At the splitting cut line 21, the length of each cut can be 0.3 mm or more and 40 mm or less, preferably 0.5 mm or more and 35 mm or less, and more preferably 1 mm or more and 30 mm or less. Also, the length of each tie can be 0.3 mm or more and 2.5 mm or less, preferably 0.5 mm or more and 1.5 mm or less, and more preferably 0.8 mm or more and 1.2 mm or less.

[0066] The lid 22 of the outlet 20 is provided with triggers (not shown) at both ends in the longitudinal direction (X direction). The triggers are made up of tearing lines. The tearing lines are perforations in which cuts and ties are arranged alternately, similar to the lid 22, and when a tie breaks, the cuts on both sides become continuous cuts.

[0067] In this embodiment, when the tearing line of the trigger is opened, an opening (not shown) and a flap (not shown) that is partially connected to the lid 22 are formed. Then, by inserting a fingertip into the opening and pulling up the folded flap and lid 22, the lid 22 is separated from the top surface 11, and an outlet 20 (opening) is formed (Figure 2).

[0068] Furthermore, a resin film (not shown) having slits in the longitudinal direction (X direction) may be provided at the outlet 20 of the top surface 11 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 200).

[0069] The resin film is fixed to the underside of the top surface 11 by adhesive applied around the outlet 20. The sheet S is removed to the outside through the slit in the resin film. The resin film can be made of polyethylene or polypropylene, but is not limited to these materials.

[0070] The sheet storage box 200 has openings 50 and 60 formed on the sides (end faces) 15 and 16 of the box body 10 for dismantling the box body 10 (Figures 3 and 4). Here, the openings 50 and 60 serve as triggers for inserting fingers or fingertips to dismantle the box body 10 after use of the sheet storage box 200.

[0071] Opening 50 is formed in the bottom flap 152 between the edge 151A of the top flap 151 and the bottom surface 12, closer to the edge 151A, and between the edge 153A of the side flap 153 and the edge 154A of the side flap 154 ​​(Figure 4). Opening 60 is formed in the bottom flap 162 between the edge 161A of the top flap 161 and the bottom surface 12, closer to the edge 161A, and between the edge 163A of the side flap 163 and the edge 164A of the side flap 164 (Figure 3).

[0072] The sheet storage box 200 has opening lines 70 and 80 formed on its end faces 15 and 16, which, when opened, create openings 50 and 60. The opening lines 70 and 80 are characterized by alternating cuts C and ties T (uncut portions between two cuts C), where a tie T breaks and the adjacent cuts C become a continuous cut.

[0073] Furthermore, at the splitting cut lines 70 and 80, the length of each cut C can be 0.3 mm or more and 40 mm or less, preferably 0.5 mm or more and 35 mm or less, and more preferably 1 mm or more and 30 mm or less. Also, the length of each tie T can be 0.3 mm or more and 2.5 mm or less, preferably 0.5 mm or more and 1.5 mm or less, and more preferably 0.8 mm or more and 1.2 mm or less.

[0074] In this embodiment, as shown in Figure 3, the tear line 70 is composed of a channel portion 71 and a curved portion 72 and is formed on the bottom flap 152 of the end face 15. The opening 50 corresponds to the portion enclosed by the channel portion 71 and the curved portion 72 of the tear line 70 (a part 15C of the end face 15). The curved portion 72 of the tear line 70 corresponds to a part of the periphery 51 of the opening 50 (Figure 3).

[0075] Furthermore, as shown in Figure 4, the splitting cut line 80 is composed of a channel portion 81 and a curved portion 82, and is formed on the bottom flap 162 of the end face 16. The opening 60 corresponds to the portion enclosed by the channel portion 81 and the curved portion 82 of the splitting cut line 80 (part 16C of the end face 16). The curved portion 82 of the splitting cut line 80 corresponds to a part of the periphery 61 of the opening 60 (Figure 4).

[0076] When the curved portion 72 of the cutting line 70 for opening is opened, a fragment (not shown) is formed with a part of the channel portion 71 as its base, and the opening becomes one in which a part 15C of the end face 15 is surrounded by a part of the periphery 51 of the opening 50 and a part 52 of the edge 151A of the top flap 151 (Figure 3).

[0077] When the curved portion 82 of the cutting line 80 for opening is cut, the opening 60 becomes an opening in which a fragment (not shown) with a part of the channel portion 81 as its base is formed, and a part 16C of the end face 16 is surrounded by a part of the peripheral edge 61 of the opening 60 and a part 62 of the edge 161A of the top flap 161.

[0078] On the end face 15, when a fingertip is inserted into the opening 50, the periphery 51 of the opening 50 (the curved portion 72 of the opening cut line 70) splits open, forming an opening. Similarly, on the end face 16, when a fingertip is inserted into the opening 60 of the end face 16, the periphery 61 of the opening 60 (the curved portion 82 of the opening cut line 80) splits open, forming an opening.

[0079] Then, by inserting the fingertip into the opening 50 and hooking it onto a part 52 of the edge 151A of the top flap 151, and pulling it in the longitudinal direction (X direction) while simultaneously pulling it upward in the height direction (Z direction), the top flap 151 is separated from the bottom flap 152, and at the same time, the bottom flap 152 is also separated from the side flaps 153 and 154.

[0080] Furthermore, if the fingertip inserted into the opening 50 is hooked onto a part 62 of the edge 161A of the top flap 161 and pulled in the longitudinal direction (X direction) while being pulled upward in the height direction (Z direction), the top flap 161 is separated from the bottom flap 162, and at the same time, the bottom flap 162 is separated from the side flaps 163 and 164.

[0081] On the end face 15, the bottom flap 152, from which the top flap 151 has been peeled off, has notches (not shown) corresponding to the channel portion 71 and the curved portion 72 of the opened tearing line 70. Meanwhile, on the back surface of the top flap 151 on the edge 151A side that has been torn from the bottom flap 152, a portion of the bottom flap 152 corresponding to these notches is attached as a broken fragment (not shown).

[0082] Furthermore, on the end face 16, the bottom flap 162 from which the top flap 161 has been peeled off has notches (not shown) corresponding to the channel portion 81 and the curved portion 82 of the opened tearing line 80. On the other hand, on the back surface of the top flap 161 on the edge 161A side that has been torn from the bottom flap 162, a portion of the bottom flap 162 corresponding to these notches is attached as a broken fragment (not shown).

[0083] In this way, the sheet storage box 200 can be dismantled after use through the opening 50 on the end face 15 or the opening 60 on the end face 16. Such a dismantling structure is also disclosed in, for example, Japanese Patent Application Publication No. 2022-11180.

[0084] Returning to the description of attachment 100, attachment 100 has a base portion 110, a first locking portion 120, and second locking portions 130 and 140.

[0085] The base portion 110 is a roughly rectangular plate in plan view. The base portion 110 has a first locking portion 120 and second locking portions 130 and 140 formed thereon.

[0086] The first locking portion 120 extends from one end edge 111 of the base portion 110 in a foldable manner relative to the base portion 110 and is locked to the sheet storage box 200.

[0087] Specifically, the first locking part 120 is locked to the end face 15 of the sheet storage box 200 by being inserted into the inside of the top flap 151 of the end face 15 of the sheet storage box 200 (the gap between the top flap 151 and the bottom flap 152 and the side flaps 153 and 154) (Figures 6 and 7).

[0088] Furthermore, the first locking portion 120 is inserted into the inside of the top flap 161 of the end face 16 of the seat storage box 200 (the gap between the top flap 161 and the bottom flap 162 and side flaps 163, 164), thereby locking to the end face 16 of the seat storage box 200.

[0089] One edge 111 of the base portion 110 constitutes the base ends 120A and 120B of the first locking portion 120. Preferably, folds (parts shown by dashed lines) are formed at the base ends 120A and 120B of the first locking portion 120. This allows the first locking portion 120 to be easily bent relative to the base portion 110, and after bending, it can maintain a stable bent state.

[0090] The size of the first locking portion 120 is not limited, but it is preferable that the width A of the first locking portion 120 is less than or equal to the length K of the gap between the top flaps 151 and 161 of the end faces 15 and 16, as this makes it easier to lock onto the end faces 15 and 16 of the sheet storage box 200. Also, it is preferable that the width A of the first locking portion 120 is less than or equal to the length K of the gap between the top flaps 151 and 161, as this allows the entire first locking portion 120 to be inserted inside the top flaps 151 and 161 of the end faces 15 and 16, resulting in a more stable lock.

[0091] The second locking portions 130 and 140 are formed between the other end edge 112 and the one end edge 111 of the base portion 110, and lock the base portion 110 to the external equipment 300 (see Figure 9).

[0092] Specifically, the second locking portions 130 and 140 extend bendably from both side edges 113 and 114 of the base portion 110, and have notches 130C and 140C on one side of the edge 111 between the second locking portions 130 and 140 and the base portion 110. The notches 130C and 140C are curved toward the second locking portions 130 and 140.

[0093] The second locking portion 130 has a first extension portion 131 that extends away from the base portion 110 and a second extension portion 132 that extends in a direction that curves from the first extension portion 131 toward the first locking portion 120. The second locking portion 140 has a first extension portion 141 that extends away from the base portion 110 and a second extension portion 142 that extends in a direction that curves from the first extension portion 141 toward the first locking portion 120.

[0094] Preferably, the second locking portion 130 has a fold (shown by a dashed line) formed at the base end 130A of the second locking portion 130, which is attached to the side edge 113 of the base portion 110. This allows the second locking portion 130 to be easily bent relative to the base portion 110, and after bending, it can maintain a stable bent state.

[0095] Preferably, the second locking portion 140 has a fold (shown by a dashed line) formed at the base end 140A of the second locking portion 140, which is attached to the side edge 114 of the base portion 110. This allows the second locking portion 140 to be easily bent relative to the base portion 110, and after bending, it can maintain a stable bent state.

[0096] The size of the second locking parts 130 and 140 is not limited, but it is preferable that the width F of the second locking parts 130 and 140 (tip 130B, 140B) be greater than or equal to the distance J between the second extensions 132 and 142 and the base 110, in order to ensure high strength of the second locking parts 130 and 140. Furthermore, it is preferable that the distance J between the second extensions 132 and 142 and the base 110 is greater than the cross-sectional diameter of the external equipment (towel rack bar 300) described later, in order to facilitate locking to the external equipment.

[0097] Furthermore, it is preferable that the length G of the second locking parts 130 and 140 is greater than or equal to the length E of the base part 110, as this makes it less likely for the second locking parts 130 and 140 to come off the external equipment (towel rack 300) to which they are locked (see Figure 9). Also, if the length G of the second locking parts 130 and 140 is longer than the length E of the base part 110, it is preferable that the tips 130B and 140B of the second locking parts 130 and 140 are supported by the end face 15 or end face 16 of the sheet storage box 200 which is tilted when suspended, thus stabilizing the locking of the attachment 100.

[0098] The attachment 100 according to this embodiment further has a third locking portion 150 that extends from the base end (one edge 111) on the base portion 110 side of the first locking portion 120 and locks to the sheet storage box 200.

[0099] In this embodiment, when the first locking portion 120 is bent relative to the base portion 110, a third locking portion 150 is formed extending toward the base portion 110 from the base ends 120A and 120B of the first locking portion 120. The third locking portion 150 is locked to the opening 50 of the end face 15 or the opening 60 of the end face 16, while the first locking portion 120 is locked to the top flap 151 of the end face 15 or the top flap 161 of the end face 16 of the sheet storage box 200 (Figure 8).

[0100] The size of the third locking portion 150 is not limited, but it is preferable that the width C of the third locking portion 150 is less than or equal to the diameter L of the openings 50 and 60 of the end faces 15 and 16, in order to facilitate locking of the third locking portion 150 to the openings 50 and 60 of the end faces 15 and 16. Furthermore, it is preferable that the length D of the third locking portion 150 is more than half the diameter L of the openings 50 and 60 of the end faces 15 and 16, in order to stably lock the third locking portion 150 to the openings 50 and 60 of the end faces 15 and 16.

[0101] Furthermore, in the attachment 100, when the first locking portion 120 is bent relative to the base portion 110, a through hole 110A is formed near one end edge 111 of the base portion 110, corresponding to the third locking portion 150.

[0102] In this embodiment, a channel-shaped slit ST is formed in advance in the base portion 110. When the first locking portion 120 is bent relative to the base portion 110, a third locking portion 150 is formed corresponding to the slit ST, and a through hole 110A is formed on the base portion 110 side.

[0103] The attachment 100 is formed by cutting out a portion of the sheet storage box 200 (see Figure 5). Specifically, a tearing line (perforation) M corresponding to the contour shape of the attachment 100 is provided on the bottom surface 12 of the sheet storage box 200. The perforation M consists of a cut C and a tie T. The cut C and tie T can be formed in the same way as the cut and tie of the lid 22 described above.

[0104] The attachment 100 may be a separate component from the seat storage box 200.

[0105] In this embodiment, a first locking portion 120 extending from one edge 111 of the base portion 110 is locked to the sheet storage box 200, and second locking portions 130 and 140 formed between the other edge 112 and the one edge 111 of the base portion 110 lock the base portion 110 to external equipment (towel rack 300), thereby allowing the sheet storage box 200 to be suspended from the external equipment 300 (Figure 9).

[0106] Therefore, using the attachment 100 of this embodiment, the placement of the sheet storage box 200 is less restricted. In addition, the sheet storage box 200 suspended from the external equipment 300 can be used hygienically (Figure 9).

[0107] In this embodiment, the second locking portions 130 and 140 extending from both side edges 113 and 114 of the base portion 110 have notches 130C and 140C, where one edge 111 side between the second locking portions 130 and 140 and the base portion 110 is cut out. As a result, when the second locking portions 130 and 140 are bent relative to the base portion 110, the notches 130C and 140C of the second locking portions 130 and 140 are positioned opposite to the direction in which the other edge 112 of the base portion 110 extends.

[0108] Therefore, when the external equipment is a towel rack bar 300, the notches 130C and 140C of the second locking parts 130 and 140 can be stably locked to the bar 300, so that the sheet storage box 200 can be hygienically installed even in wet areas such as washrooms (Figure 9).

[0109] In this embodiment, the third locking portion 150, which extends from the base end (one edge 111) of the first locking portion 120 on the base portion 110 side, is locked to the sheet storage box 200, so that the first locking portion 120 and the third locking portion 150 can be locked to two different locations on the sheet storage box 200. Therefore, the attachment 100 can be stably attached to the sheet storage box 200 (Figure 9).

[0110] In this embodiment, before the first locking portion 120 is bent relative to the base portion 110, the surface from which the third locking portion 150 extends is flush with the surface of the base portion 110. However, after the first locking portion 120 is bent relative to the base portion 110, the surface from which the third locking portion 150 extends intersects with the surface of the base portion 110. Therefore, in the region where the third locking portion 150 was located before the first locking portion 120 was bent relative to the base portion 110, a through hole 110A corresponding to the third locking portion 150 is formed after the first locking portion 120 is bent relative to the base portion 110.

[0111] In this embodiment, with this configuration, when the first locking portion 120 is bent relative to the base portion 110, a through hole 110A is formed near one end edge 111 of the base portion 110, corresponding to the third locking portion 150. Therefore, the through hole 110A formed near one end edge 111 of the base portion 110 can constitute second locking portions 130 and 140 that lock the base portion 110 to the external equipment 300. As a result, regardless of whether the external equipment is a bar 300 such as a towel rack, the second locking portions 130 and 140 can be locked to the external equipment by using a member such as a hook.

[0112] In this embodiment, a portion of the sheet storage box 200 is cut out to form the attachment 100. This allows the attachment 100 to be used only when the sheet storage box 200 needs to be suspended. Therefore, in this embodiment, the attachment 100 can be prepared according to the environment in which the sheet storage box 200 is installed.

[0113] Although embodiments of the present invention have been described above, the present invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope of the invention as described in the claims. [Explanation of Symbols]
