Description

[Technical Field]

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

[0002] In recent years, laminated toilet paper that can be easily pulled out and used with one hand has become widely used in caregiving and other situations (see, for example, Patent Document 1). Furthermore, a technology is known in which a sheet storage box containing such laminated toilet paper is attached to a roll holder for roll-type toilet paper (see, for example, Patent Documents 2 to 4). [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2010-22799 [Patent Document 2] Japanese Patent Publication No. 2001-314346 [Patent Document 3] Patent No. 3511956 [Patent Document 4] Patent No. 5602531 [Overview of the project] [Problems that the invention aims to solve]

[0004] However, in a configuration where the seat storage box is attached to the roll holder, if the seat storage box is hooked onto the inner arm of the roll holder, the direction in which the seat is pulled out is restricted to downward. Also, if a locking piece with a cutout in part of the seat storage box is inserted into the gap of the roll holder, the mounting becomes unstable. Furthermore, if it is attached via an attachment of a separate component, the mounting becomes complicated.

[0005] The objective of this invention is to provide a sheet storage box that is easy to attach to a roll holder, allows for stable attachment, and makes it easy to pull out the sheets. [Means for solving the problem]

[0006] A first aspect of the present invention provides a sheet storage box used attached to a roll sheet holder equipped with an arm, comprising: a rectangular parallelepiped body for housing a sheet stack of multiple sheets; an outlet formed on the top surface of the body for removing the sheets; a first locking portion formed on the side surface of the body for which the arm is inserted and locked; and a second locking portion formed on the same surface as the side surface at a predetermined distance from the first locking portion, for which the arm is inserted and locked while locked to the first locking portion.

[0007] In the first embodiment, the arms of the roll sheet holder are inserted and locked into a first locking portion formed on the side of the main body of the sheet storage box, and the arms of the roll sheet holder are inserted and locked into a second locking portion formed on the same plane as the side of the main body. As a result, the side of the main body is fixed to the arms of the roll sheet holder, so that the sheet storage box can be stably attached to the roll sheet holder.

[0008] Furthermore, in the first embodiment, the sheet storage box can be directly attached to the roll sheet holder, so the sheet storage box can be attached to the roll sheet holder without using a separate component such as an attachment. Therefore, according to the first embodiment, the attachment of the sheet storage box to the roll sheet holder becomes easier.

[0009] Furthermore, in the first embodiment, the side of the sheet storage box body can be locked to the roll sheet holder such that the bottom surface of the body faces the inner wall of the toilet to which the roll sheet holder is fixed. Therefore, according to the first embodiment, with the sheet storage box fixed to the roll sheet holder, the top surface of the body with the opening formed therein can be turned towards the user, making it easier to pull out the sheets from the opening.

[0010] A second aspect of the present invention provides a sheet storage box according to the first aspect, wherein the first locking portion and the second locking portion are openings.

[0011] In the second embodiment, the openings in the first and second locking portions facilitate the insertion of the arms into the first and second locking portions. Therefore, according to the second embodiment, the attachment of the sheet storage box to the roll sheet holder becomes even easier.

[0012] A third aspect of the present invention provides a sheet storage box according to the first or second aspect, wherein the side surface is one long side surface of the main body, and the first locking portion and the second locking portion are formed side by side in the longitudinal direction of the main body.

[0013] In the third embodiment, the side of the main body is one of the long sides of the main body, and the first locking portion and the second locking portion are formed side by side in the longitudinal direction of the main body, so that the sheet storage box can be fixed to the roll sheet holder so that the longitudinal direction of the sheet storage box is horizontal. As a result the opening of the sheet storage box is positioned closer to the roll sheet holder, making it even easier to pull out sheets from the opening.

[0014] A fourth aspect of the present invention provides a sheet storage box according to any one of the first to third aspects, wherein the first locking portion and the second locking portion are formed on extensions extending from the side surface.

[0015] In the fourth embodiment, a first locking portion and a second locking portion are formed on an extension portion extending from the side of the main body, so that a sheet storage box can be placed below the roll sheet holder with the arms locked to the first locking portion and the second locking portion. Furthermore, because the first locking portion and the second locking portion are formed on such an extension portion, a sheet storage box can be easily and stably attached to the roll sheet holder even if the roll sheet holder is composed of a pair of arms connected to a pair of side plates.

[0016] The fifth aspect according to the present invention provides the sheet storage box according to the fourth aspect, in which a cleavage cut line is formed on the side surface, and the extension part is formed by cleavage of the cleavage cut line.

[0017] In the fifth aspect, by providing a cleavage cut line on the side surface of the main body, which forms an extension part when cleaved, the extension part can be formed only when the sheet storage box is attached to the roll sheet holder and used.

[0018] The sixth aspect according to the present invention provides the sheet storage box according to any one of the fifth aspects, in which the extension part is constituted by a part of the side surface, and a fold is provided at the base end of the extension part.

[0019] In the sixth aspect, since a fold is provided at the base end of the extension part constituted by a part of the side surface of the main body, the extension part can be easily unfolded through the fold. Therefore, even when the extension part is formed by a part of the side surface of the main body, it is easy to attach the sheet storage box to the roll sheet holder.

[0020] The seventh aspect according to the present invention provides the sheet storage box according to any one of the fourth to sixth aspects, in which cuts continuous with both ends of the base end of the extension part are provided on the side surface.

[0021] In the seventh aspect, since cuts continuous with the extension part are provided on the side surface of the main body at both ends of the base end of the extension part, when forming the extension part by cleaving the cleavage cut line, the force applied to the base end of the extension part can be released to the cuts continuous with both ends of the base end. Therefore, it is possible to prevent the base end of the extension part formed by cleaving the cleavage cut line from being torn.

Effect of the Invention

[0022] According to one aspect of the present invention, it is possible to provide a sheet storage box that is easy to attach to a roll holder, enables stable attachment, and allows the sheet to be easily pulled out.

[0024] Embodiments of the present invention will be described below with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding components may be denoted by the same reference numerals and their descriptions may be omitted. Also, for ease of understanding, the scale of each component in the drawings may differ from that of the actual components.

[0025] In this specification, a three-dimensional Cartesian coordinate system with three axes (X, Y, and Z directions) is used, where the longitudinal direction (left-right direction) of the sheet storage box or sheet stack is the X direction, the transverse direction (front-back direction) is the Y direction, and the height direction (up-down direction) is the Z direction.

[0026] Furthermore, in this specification, deviations in each direction are permitted to the extent that they do not impair the function and effect of the embodiment.

[0027] <First Embodiment> Figure 1 shows a sheet storage box according to the first embodiment of the present invention, and Figure 2 shows a sheet stack housed in the sheet storage box. Figure 3 shows an example of a roll sheet holder with a roll sheet attached, and Figure 4 shows an example of a roll sheet holder. Figure 5 shows the sheet storage box of the first embodiment attached to the roll sheet holder.

[0028] The sheet storage box 100 may be pre-filled with sheets S, or it may be empty and replenished with sheets S. Furthermore, the sheet storage box 100 may be a disposable type that is discarded after use, or it may be a reusable type such as a dispenser.

[0029] As shown in Figure 1, the sheet storage box 100 according to this embodiment is composed of a main body 10 formed in a substantially rectangular parallelepiped (including a cube) shape. The main body 10 has a top surface 11, a bottom surface 12, a pair of long sides 13 and 14, and a pair of short sides 15 and 16.

[0030] The top surface 11 and the bottom surface 12 face each other in the height direction (Z direction). The pair of long sides 13 and 14 face each other in the short direction (Y direction). The pair of short sides 15 and 16 face each other in the longitudinal direction (X direction). Note that the top surface 11 is an example of the top surface of the sheet storage box of the present invention.

[0031] The material of the main body 10 is not limited; for example, base paper made primarily from pulp can be used. Here, base paper refers to a hard, thick paper that serves as the material for assembling the main body 10. 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.

[0032] Furthermore, while there are no restrictions on the basis weight of the base paper, from the perspective of ensuring sufficient strength for use, 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).

[0033] 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 base paper is coated cardboard, the paper thickness of the base paper 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.

[0034] The dimensions of the main body 10 are not limited and can be determined by the quantity and dimensions of the sheets S to be stored in the sheet storage box 100. For example, the length of the main 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.

[0035] Furthermore, the width of the main body 10 in the shorter direction (Y direction) can be 100 mm or more and 150 mm or less, preferably 100 mm or more and 130 mm or less. In addition, the height of the main 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.

[0036] The main body 10 houses multiple stacked sheets S. In this embodiment, the multiple sheets S housed in the main body 10 are composed of a sheet laminate SL in which multiple sheets S are stacked in the stacking direction (Z direction, LD direction) (Figures 1 and 2).

[0037] The material of the sheet S is not particularly limited, and for example, sheets such as paper, non-woven fabric or cloth can be used, and preferably a paper sheet (hereinafter referred to as a paper sheet). A known composition in the paper sheet can be used as the pulp composition. The blending ratio of the pulp can be, for example, 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

[0038] The pulp composition of the sheet S is not particularly limited. For example, softwood pulps such as NBKP (softwood kraft pulp) and NUKP (softwood unbleached pulp), and hardwood pulps such as LBKP (hardwood kraft pulp) and LUKP (hardwood unbleached pulp) can be used in any ratio.

[0039] In addition, the ratio of hardwood pulp to softwood pulp is not limited, but is preferably 10:90 to 80:20, and more preferably a pulp composition in which the ratio of hardwood pulp to softwood pulp is higher. Further, wastepaper pulp may be used as the pulp contained in the sheet S.

[0040] Also, the basis weight of the sheet S is not particularly limited, but depending on the ply number, in the case of paper, it is 5 g / m 2 or more and 80 g / m 2 or less, and in the case of non-woven fabric, it is 20 g / m 2 or more and 100 g / m 2 or less, which is desirable. The basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0041] Also, the thickness of the sheet S is not particularly limited, and the paper thickness measured under the environment of JIS P 8111 (1998) can be adopted. For example, the paper thickness of the paper sheet constituting the sheet S can be 1 ply (in the case of 2 plies, per 2 plies), 50 μm or more and 500 μm or less, and preferably 60 μm or more and 330 μm or less.

[0042] The sheet S may be embossed. Such embossing can be carried out by known embossing methods. The embossing method is not particularly limited and examples include the steel rubber method and the steel match method. Among these, the steel match method is preferred.

[0043] The form of sheet S is not particularly limited and can be applied to items such as toilet paper, tissue paper, paper towels, kitchen paper, baby or adult diapers, and sanitary napkins. Note that sanitary tissues such as paper towels and tissue paper also include sanitary tissues containing moisturizing ingredients (e.g., lotion tissues). Furthermore, sheet S can be used for industrial, household, or portable purposes.

[0044] 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.

[0045] The dimensions of sheet S are, for example, 120-260 mm in length and 80-280 mm in width in the case of toilet paper. Furthermore, the number of plies is preferably one or more, and more preferably two.

[0046] 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.

[0047] The dimensions of the sheet laminate SL are, for example, in the case of toilet paper, 80 mm to 280 mm in the longitudinal direction (X direction), 60 mm to 130 mm in the transverse direction (Y direction), and 20 mm to 140 mm in height in the lamination direction (Z direction, LD direction). Such sheet laminates can be manufactured, for example, by a rotary type or multi-stand type interfolder.

[0048] The sheet S (sheet laminate SL) may be stored directly in the main body 10 of the sheet storage box 100, or it may be stored as a film package wrapped in resin film.

[0049] An opening 20 is formed on the top surface 11 of the main body 10. The opening 20 is designed for the sheet S to be pulled out. The opening 20 extends in the longitudinal direction (X direction) of the main body 10 with a predetermined width in the short direction (Y direction) perpendicular to the longitudinal direction (X direction) of the main body 10. Here, perpendicularity may include approximately perpendicularity.

[0050] The dispensing opening 20 may be covered by the lid 20A before use of the sheet storage box 100. Triggers (not shown) formed by semicircular or other notches may be provided at both ends of the lid 20A.

[0051] The lid 20A is connected to the top surface 11 via perforations or other tearing lines M. Here, the tearing lines are intermittent lines in which cuts and ties (uncut portions between two cuts) are arranged alternately, and when a tie breaks, the cuts on both sides become continuous cuts. When using the sheet storage box 100, the lid 20A is removed by tearing along these tearing lines M, forming an opening 20.

[0052] The shape of the outlet 20 is not particularly limited as long as it is a shape that allows the sheet S housed in the main body 10 to be pulled out from the top surface 11 side. In this embodiment, the shape of the outlet 20 is elliptical in plan view, but it may also be an elongated rectangle, a racetrack shape, or the like in plan view.

[0053] The outlet 20 may be covered with a film material (not shown). The material of the film material is not particularly limited, and for example, polyethylene, polypropylene, and other resins can be used. As the resin, biodegradable materials (such as biodegradable plastics such as polylactic acid) and biomass materials (renewable organic resources of biological origin, such as biomass film, excluding fossil resources) can be used.

[0054] The shape of the film material is not particularly limited, as long as it covers the outlet 20. In this embodiment, a rectangular film material is used in plan view.

[0055] The thickness of the film material is not particularly limited, and is, for example, 10 μm or more and 50 μm or less, preferably 15 μm or more and 45 μm or less, and more preferably 20 μm or more and 40 μm or less.

[0056] The film material has slits (not shown) formed in it. The shape of the slits is not particularly limited. In this embodiment, with the film material covering the outlet 20, a linear slit extending in the longitudinal direction (X direction) of the main body 10 is formed in the film material. The sheet S removed from the outlet 20 is removed to the outside through the slits in the film material.

[0057] The film material is adhered to the back surface of the top surface 11. Specifically, an adhesive portion (not shown) is provided in the overlapping region (not shown) where the film material overlaps outside the outlet 20 on the back surface of the top surface 11, to which the film material is adhered. The film material is adhered to the overlapping region via this adhesive portion.

[0058] The configuration of the adhesive portion is not particularly limited. For example, a known adhesive can be applied in advance to the portion of the back surface of the top surface 11 corresponding to the overlapping area, and the film material can be brought into contact with the portion to which the adhesive has been applied. This fixes the film material to the portion to which the adhesive has been applied, and this fixed portion of the film material constitutes the adhesive portion.

[0059] Known adhesives include acrylic-vinyl acetate copolymers and ethylene-vinyl acetate polymer aqueous emulsions.

[0060] Because this film material is adhered to the underside of the top surface 11, the sheet S removed from the outlet 20 passes through the slits in the film material and does not come into contact with the edge of the outlet 20, thus preventing the sheet S from tearing during removal. In addition, as the next sheet S is removed, it becomes possible to use the sheet laminate SL in a pop-up manner because the next sheet S is locked into the slits in the film material.

[0061] Furthermore, the dispensing opening 20 may be left open and not covered by the film material. For example, by placing the film packaging of the sheet laminate SL in a sheet storage box 100 in which the opening of the dispensing opening 20 is not covered by the film material, the sheet laminate SL can be used in a pop-up manner even if the dispensing opening 20 is not covered by the film material.

[0062] The sheet storage box 100 of the first embodiment is used by being attached to a roll sheet holder 80. The roll sheet holder 80 is a holder for attaching and using roll sheets TR such as toilet paper shown in Figure 3.

[0063] The roll sheet holder 80 comprises a base 81, a cover 82, and an arm 83, as shown in Figures 3 and 4.

[0064] The base 81 forms the base of the roll sheet holder 80, and the roll sheet holder 80 is attached to the interior wall of the toilet, etc., via the back of the base 81. The cover 82 is fixed to the base 81 and rotatably supports the arm 83.

[0065] The arm 83 is rotatably supported on the base 81 via a cover 82 at its upper part 83A. The arm 83 can rotatably lock a roll of toilet paper to its lower part 83B (see Figure 3). The shape of the arm 83 is not particularly limited, but for example, it could be a U-shaped section made from a single rod-shaped member.

[0066] The roll sheet holder 80 may also be provided with a top plate (not shown). One end of the top plate is rotatably connected to the upper part 83A of the arm 83. The other end of the top plate, opposite to the arm 83, constitutes a paper cutting section (not shown). The paper cutting section has a curved edge at the end of the top plate, allowing it to cut the roll sheet TR.

[0067] The material of the roll sheet holder 80 is not particularly limited and may be made of resin, metal, etc.

[0068] The sheet storage box 100 of this embodiment is used by being attached to such a roll sheet holder 80 (see Figure 5). The sheet storage box 100 has a first locking portion 30 and a second locking portion 40.

[0069] In the first embodiment, the first locking portion 30 is formed on the side surface of the main body 10. In the first embodiment, the first locking portion 30 is formed on one of the long side surfaces 13 of the main body 10, but the side surface of the main body 10 on which the first locking portion 30 is formed is not limited to the long side surface 13, but may be a long side surface 14, a short side surface 15, or a short side surface 16.

[0070] The arm 83 of the roll sheet holder 80 is inserted into and locked to the first locking portion 30. The first locking portion 30 is preferably an opening OP1, as shown in Figure 1. The opening OP1 constituting the first locking portion 30 may be formed by tearing a tearing line (not shown), such as a perforation.

[0071] The shape of the first locking portion 30 is not particularly limited, as long as it is a shape through which the arm 83 of the roll sheet holder 80 can be inserted. In the first embodiment, the shape of the first locking portion 30 is a rectangle in plan view, but it may also be a polygon other than a rectangle, a circle, an ellipse, a racetrack shape, etc.

[0072] The size of the first locking portion 30 is not particularly limited, as long as it is large enough for the arm 83 of the roll sheet holder 80 to pass through. In the first embodiment, the size of the first locking portion 30 is larger than the cross-sectional diameter of the arm 83 of the roll sheet holder 80, but it may also be smaller than the cross-sectional diameter of the arm 83 of the roll sheet holder 80 to the extent that the arm 83 of the roll sheet holder 80 fits into the first locking portion 30.

[0073] The second locking portion 40 is formed on the same plane as the side surface of the main body 10 on which the first locking portion 30 is formed. In the first embodiment, the second locking portion 40 is formed on the long side surface 13 on which the first locking portion 30 is formed. However, the side surface of the main body 10 on which the second locking portion 40 is formed is not limited to one of the long side surfaces 13. For example, if the first locking portion 30 is formed on the other long side surface 14, the side on which the second locking portion 40 is formed will be the other long side surface 14.

[0074] The second locking portion 40 is formed at a predetermined distance from the first locking portion 30, and is locked so that the arm 83 of the roll sheet holder 80 can be inserted while locked to the first locking portion 30. The second locking portion 40 is preferably an opening OP2, as shown in Figure 1. The opening OP2 constituting the second locking portion 40 may be formed by tearing a tearing line (not shown), such as a perforation.

[0075] In this specification, the predetermined interval refers to the shortest distance between the first locking portion 30 and the second locking portion 40. The predetermined interval is arbitrary as long as the arm 83 of the roll sheet holder 80 is locked to the second locking portion 40 while locked to the first locking portion 30. In the first embodiment, the shortest distance D1 between the first locking portion 30 and the second locking portion 40 is shorter than the length L1 of the lower part 83B of the arm 83 of the roll sheet holder 80 (see Figure 5).

[0076] As in the first embodiment, if the side surface of the main body 10 on which the first locking portion 30 and the second locking portion 40 are formed is a long side surface 13, then the first locking portion 30 and the second locking portion 40 are formed side by side in the longitudinal direction (X direction) of the main body 10.

[0077] In the first embodiment, as described above, the arm 83 of the roll sheet holder 80 is inserted and locked into the first locking portion 30 formed on the side surface 13 of the main body 10 of the sheet storage box 100, and the arm 83 of the roll sheet holder 80 is inserted and locked into the second locking portion 40 formed on the same surface as the side surface 13 of the main body 10. As a result, the side surface 13 of the main body 10 is fixed to the arm 83 of the roll sheet holder 80, so that the sheet storage box 100 can be stably attached to the roll sheet holder 80.

[0078] Furthermore, in the first embodiment, the sheet storage box 100 can be directly attached to the roll sheet holder 80, so the sheet storage box 100 can be attached to the roll sheet holder 80 without using a separate component such as an attachment. Therefore, according to the first embodiment, the attachment of the sheet storage box 100 to the roll sheet holder 80 becomes easier.

[0079] Furthermore, in the first embodiment, the side surface 13 of the main body 10 of the sheet storage box 100 can be locked to the roll sheet holder 80 such that the bottom surface 12 of the main body 10 faces the inner wall of the toilet where the roll sheet holder 80 is fixed. Therefore, according to the first embodiment, with the sheet storage box 100 fixed to the roll sheet holder 80, the top surface 11 of the main body 10, where the dispensing opening 20 is formed, can be turned towards the user, making it easier to pull out the sheets S from the dispensing opening 20.

[0080] In the first embodiment, as described above, the first locking portion 30 and the second locking portion 40 are open (openings OP1 and OP2), which makes it easier to insert the arm 83 into the first locking portion 30 and the second locking portion 40. Therefore, according to the first embodiment, it becomes even easier to attach the sheet storage box 100 to the roll sheet holder 80.

[0081] In the first embodiment, as described above, the side surface of the main body 10 is one of the long sides 13 of the main body 10, and the first locking portion 30 and the second locking portion 40 are formed side by side in the longitudinal direction (X direction) of the main body 10, so that the sheet storage box 100 can be fixed to the roll sheet holder 80 such that the longitudinal direction (X direction) of the sheet storage box 100 is horizontal. As a result, the outlet 20 of the sheet storage box 100 is positioned closer to the roll sheet holder 80, making it even easier to pull out the sheets S from the outlet 20.

[0082] <Second Embodiment> Figure 6 shows a sheet storage box according to the second embodiment, and Figure 7 shows the sheet storage box according to the second embodiment attached to a roll sheet holder. In the second embodiment shown in Figures 6 and 7, parts common to the first embodiment shown in Figures 1 and 5 are denoted by the same or corresponding reference numerals and their descriptions are omitted.

[0083] In the second embodiment, the first locking portion 30 is formed on one of the short sides 15 of the main body 10. In the second embodiment, the side of the main body 10 on which the first locking portion 30 is formed is not limited to one of the short sides 15, but may be the other short side 16. The first locking portion 30 is preferably an opening OP1, as shown in Figure 6.

[0084] Furthermore, the second locking portion 40 is formed on the short side surface 15 on which the first locking portion 30 is formed. In the second embodiment, the side surface of the main body 10 on which the second locking portion 40 is formed is not limited to one of the short side surfaces 15. For example, if the first locking portion 30 is formed on the other short side surface 16, the side surface of the main body 10 on which the second locking portion 40 is formed will be the other long side surface 16. The second locking portion 40 is preferably an opening OP2, as shown in Figure 6.

[0085] In the second embodiment, the shortest distance D2 between the first locking portion 30 and the second locking portion 40 is shorter than the length L1 of the lower part 83B of the arm 83 of the roll sheet holder 80 (see Figure 7). Also, as in the second embodiment, when the side surface of the main body 10 on which the first locking portion 30 and the second locking portion 40 are formed is the short side surface 15, the first locking portion 30 and the second locking portion 40 are formed side by side in the short direction (Y direction) of the main body 10.

[0086] In the second embodiment, as described above, the arm 83 of the roll sheet holder 80 is inserted and locked into the first locking portion 30 formed on the short side 15 of the main body 10 of the sheet storage box 100, and the arm 83 of the roll sheet holder 80 is inserted and locked into the second locking portion 40 formed on the same plane as the short side 15. As a result, the short side 15 of the main body 10 is fixed to the arm 83 of the roll sheet holder 80, so that the sheet storage box 100 can be stably attached to the roll sheet holder 80.

[0087] Furthermore, in the second embodiment, the sheet storage box 100 can be directly attached to the roll sheet holder 80, so the sheet storage box 100 can be attached to the roll sheet holder 80 without using a separate component such as an attachment. Therefore, according to the second embodiment, the attachment of the sheet storage box 100 to the roll sheet holder 80 becomes easier.

[0088] Furthermore, in the second embodiment, the short side 15 of the main body 10 of the sheet storage box can be locked to the roll sheet holder 80 such that the bottom surface 12 of the main body 10 faces the inner wall of the toilet to which the roll sheet holder 80 is fixed. Therefore, according to the second embodiment, with the sheet storage box 100 fixed to the roll sheet holder 80, the top surface 11 of the main body 10, which has the outlet 20 formed thereon, can be turned towards the user, making it easier to pull out the sheets S from the outlet 20.

[0089] In the second embodiment, as described above, the first locking portion 30 and the second locking portion 40 are open (openings OP1 and OP2), which makes it easier to insert the arms 83 of the roll sheet holder 80 into the first locking portion 30 and the second locking portion 40. Therefore, according to the second embodiment, it becomes even easier to attach the sheet storage box 100 to the roll sheet holder 80.

[0090] Although not described herein, the first embodiment (the configuration shown in Figure 1) described above may also be applied to the second embodiment (the configuration shown in Figure 6).

[0091] <Third Embodiment> Figure 8 shows a sheet storage box of the third embodiment. Figure 9 shows another example of a roll sheet holder with a roll sheet installed, and Figure 10 shows another example of a roll sheet holder. Figure 11 shows the sheet storage box of the third embodiment attached to the roll sheet holder. In the third embodiment shown in Figures 8 and 11, parts common to the first embodiment shown in Figures 1 and 5 are denoted by the same or corresponding reference numerals and their descriptions are omitted.

[0092] The sheet storage box 100 of the third embodiment has a first locking portion 30 and a second locking portion 40 and is used when attached to a roll sheet holder 90. The roll sheet holder 90 is a holder for attaching and using roll sheets TR such as toilet paper shown in Figure 9.

[0094] The rear plate 91 forms the base of the roll sheet holder 90, and the roll sheet holder 90 is attached to the interior wall of the toilet, etc., via the back surface of the rear plate 91. The side plate 92 is connected to the rear plate 91 and supports the roll of toilet paper so that it can rotate freely.

[0095] The top plate 93 is rotatably connected to the side plate 92. The end of the top plate 93 opposite to the rear plate 91 forms a paper cutting section 93A. The paper cutting section 93A has a curved surface at the end of the top plate 93, allowing it to cut roll sheets TR.

[0096] Arms 94 and 95 are attached to the side plate 92 and can rotatably lock a roll of toilet paper.

[0097] The material of the roll sheet holder 90 is not particularly limited and may be resin, metal, etc.

[0098] In the sheet storage box 100 of the third embodiment, the first locking portion 30 is formed on the extension portion 50. The extension portion 50 extends from the long side surface 13. Specifically, the extension portion 50 extends from the base end 51 to the tip end 52 on the short side surface 15 side of the long side surface 13. The first locking portion 30 is formed on the tip end 52 side of the extension portion 50. As a result, the first locking portion 30 is formed on the short side surface 15 side of the long side surface 13 of the main body 10, and one arm 94 of the roll sheet holder 90 is inserted and locked into it.

[0099] The shape of the extension portion 50 is not particularly limited, as long as it is a shape that allows the arm 94 of the roll sheet holder 90 to be inserted into the first locking portion 30. In this embodiment, the shape of the extension portion 50 is rectangular in plan view, but it may also be semicircular, semielliptical, semi-racetrack, etc.

[0100] The size of the extension portion 50 is not particularly limited, as long as it is large enough for the arm 94 of the roll sheet holder 90 to pass through the first locking portion 30. In this embodiment, it is preferable that the size of the extension portion 50 is such that, with one arm 94 of the roll sheet holder 90 locked to the first locking portion 30, the side surface 13 of the main body is positioned below the lower part 92A of the side plate 92 of the roll sheet holder 90.

[0101] As shown in Figure 8, the extension portion 50 is formed from a part of the side surface 13 of the main body 10. The extension portion 50 may also be formed by tearing a perforation line M1 or the like formed on the side surface 13 of the main body 10, as shown in Figures 8 and 11. In this embodiment, the extension portion 50 is formed by tearing a channel-shaped perforation line M1 in a plan view. After tearing the perforation line M1, an opening OP3 corresponding to the extension portion 50 is formed on the side surface 13 of the main body 10 (see Figure 11).

[0102] The extension portion 50 has its base end 51 formed on the side surface 15 side of the side surface 13 of the main body 10. A fold F1 may be provided at the base end 51 of the extension portion 50. The fold F1 may be either a mountain fold or a valley fold, but a valley fold is preferred.

[0103] In the extension portion 50, it is preferable that notches 71 and 72 are provided. The notches 71 and 72 are formed on the short side 15 side of the long side 13 and are continuous with both ends 51A and 51B of the base end 51 of the extension portion 50. The shape of the notches 71 and 72 is not particularly limited, but it is preferable that they be arc-shaped, convex toward the short side 15 side, and more preferably arc-shaped.

[0104] The second locking portion 40 is formed on the extension portion 60. The extension portion 60 extends from the long side surface 13. Specifically, the extension portion 60 extends from the base end 61 to the tip end 62 on the short side surface 16 side of the long side surface 13. The second locking portion 40 is formed on the tip end 62 side of the extension portion 60. As a result, the second locking portion 40 is formed on the short side surface 16 side of the long side surface 13 of the main body 10, and the other arm 95 of the roll sheet holder 90 is locked to it so that it can be inserted through it.

[0105] The shape of the extension portion 60 is not particularly limited, as long as it is a shape that allows the arm 95 of the roll sheet holder 90 to be inserted into the second locking portion 40. In this embodiment, the shape of the extension portion 60 is rectangular in plan view, but it may also be semicircular, semielliptical, semi-racetrack, etc.

[0106] The size of the extension portion 60 is not particularly limited, as long as it is large enough for the arm 95 of the roll sheet holder 90 to pass through the second locking portion 40. In this embodiment, it is preferable that the size of the extension portion 60 is such that, with one arm 95 of the roll sheet holder 90 locked to the second locking portion 40, the side surface 13 of the main body is positioned below the lower part 92A of the side plate 92 of the roll sheet holder 90.

[0107] As shown in Figure 8, the extension portion 60 is formed from a part of the side surface 13 of the main body 10. The extension portion 60 may also be formed by tearing a perforation line M2 or the like formed on the side surface 13 of the main body 10, as shown in Figures 8 and 11. In this embodiment, the extension portion 60 is formed by tearing a channel-shaped perforation line M2 in a plan view. After tearing the perforation line M2, an opening OP4 corresponding to the extension portion 60 is formed on the side surface 13 of the main body 10 (see Figure 11).

[0108] The base end 61 of the extension 60 is formed on the side surface 16 side of the side surface 13 of the main body 10. A fold F2 may be provided at the base end 61 of the extension 60. The fold F2 may be either a mountain fold or a valley fold, but a valley fold is preferred.

[0109] In the extension portion 60, it is preferable that notches 73 and 74 are provided. The notches 73 and 74 are formed on the short side 16 side of the long side 13 and are continuous with both ends 61A and 61B of the base end 61 of the extension portion 60. The shape of the notches 73 and 74 is not particularly limited, but it is preferable that they be arc-shaped, convex toward the short side 16 side, and more preferably arc-shaped.

[0110] In the third embodiment, as described above, the arm 94 of the roll sheet holder 90 is locked to a first locking portion 30 formed on the long side surface 13 of the main body 10 of the sheet storage box 100 so as to be insertable, and the arm 95 of the roll sheet holder 90 is locked to a second locking portion 40 formed on the same surface as the long side surface 13 so as to be insertable. As a result, the long side surface 13 of the main body 10 is fixed to the arms 94 and 95 of the roll sheet holder 90, so that the sheet storage box 100 can be stably attached to the roll sheet holder 90.

[0111] Furthermore, in the third embodiment, the sheet storage box 100 can be directly attached to the roll sheet holder 90, so the sheet storage box 100 can be attached to the roll sheet holder 90 without using a separate component such as an attachment. Therefore, according to the third embodiment, the attachment of the sheet storage box 100 to the roll sheet holder 90 becomes easier.

[0112] Furthermore, in the third embodiment, the long side surface 13 of the main body 10 of the sheet storage box can be locked to the roll sheet holder 90 such that the bottom surface 12 of the main body 10 faces the inner wall of the toilet where the roll sheet holder 90 is fixed. Therefore, according to the third embodiment, with the sheet storage box 100 fixed to the roll sheet holder 90, the top surface 11 of the main body 10, where the dispensing opening 20 is formed, can be turned towards the user, making it easier to pull out the sheets S from the dispensing opening 20.

[0113] In the third embodiment, as described above, the first locking portion 30 and the second locking portion 40 are open (openings OP1 and OP2), which makes it easier to insert the arms 94 and 95 of the roll sheet holder 90 into the first locking portion 30 and the second locking portion 40. Therefore, according to the third embodiment, it becomes even easier to attach the sheet storage box 100 to the roll sheet holder 90.

[0114] In the third embodiment, as described above, the side surface of the main body 10 is one of the long sides 13 of the main body 10, and the first locking portion 30 and the second locking portion 40 are formed side by side in the longitudinal direction (X direction) of the main body 10, so that the sheet storage box 100 can be fixed to the roll sheet holder 90 such that the longitudinal direction (X direction) of the sheet storage box 100 is horizontal. As a result, the outlet 20 of the sheet storage box 100 is positioned closer to the roll sheet holder 90, making it even easier to pull out the sheets S from the outlet 20.

[0115] In the third embodiment, as described above, the first locking portion 30 and the second locking portion 40 are formed on the extension portions 50 and 60 extending from the side surface 13 of the main body 10, respectively. This allows the sheet storage box 100 to be positioned below the roll sheet holder 90 while the arms 94 and 95 of the roll sheet holder 90 are locked to the first locking portion 30 and the second locking portion 40. Furthermore, because the first locking portion 30 and the second locking portion 40 are formed on the extension portions 50 and 60, respectively, the sheet storage box 100 can be easily and stably attached to the roll sheet holder 90 even if the roll sheet holder 90 is composed of a pair of arms 94 and 95 connected to a pair of side plates 92.

[0116] In the third embodiment, by providing tearing lines M1 and M2 on the side surface 13 of the main body 10, which form the extensions 50 and 60 when slit, the extensions 50 and 60 can be formed only when the sheet storage box 100 is attached to the roll sheet holder 90.

[0117] In the third embodiment, folds F1 and F2 are provided at the base ends 51 and 61 of the extensions 50 and 60, which are formed from a part of the side surface 13 of the main body 10, making it easier for the extensions 50 and 60 to unfold via the folds F1 and F2. Therefore, even when the extensions 50 and 60 are formed from a part of the side surface 13, it becomes easier to attach the sheet storage box 100 to the roll sheet holder 90.

[0118] In the third embodiment, notches 71, 72, 73, and 74 continuous with the extensions 50 and 60 are provided on the side surface 13 of the main body 10 at both ends 51A, 51B, 61A, and 61B of the base ends 51, 61 of the extensions 50 and 60. This allows the force applied to the base ends 51, 61 of the extensions 50 and 60 to be released into the notches 71, 72, 73, and 74 continuous with both ends 51A, 51B, 61A, and 61B when the tearing lines M1 and M2 are opened to form the extensions 50 and 60, respectively. Therefore, it is possible to prevent the base ends 51, 61 of the extensions 50 and 60 from tearing when the tearing lines M1 and M2 are opened.

[0119] Although not described herein, the first embodiment (configuration shown in Figure 1) and / or the second embodiment (configuration shown in Figure 6) described above may be applied to the third embodiment (configuration shown in Figure 8).
