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 roll holder cannot be used for both purposes. Also, if a locking piece cut out from a 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 made from 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 can be used in conjunction with a roll holder. [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 having a rear plate, a pair of side plates connected to the rear plate, and a top plate rotatably connected to the upper part of the side plates near the rear plate, the sheet storage box having a rectangular parallelepiped body for housing a sheet stack of a plurality of sheets stacked together, an outlet formed on the top surface of the body for removing the sheets, a first locking portion formed on the bottom surface of the body that engages between the top plate and the rear plate, a second locking portion formed on the bottom surface that engages between the top plate and one of the side plates, and a third locking portion formed on the bottom surface that engages between the top plate and the other side plate, wherein the first locking portion, the second locking portion and the third locking portion are formed from a part of the bottom surface.

[0007] In the first embodiment, a first locking portion is formed on the bottom surface of the main body, which is locked between the rear plate and the main body; a second locking portion is formed between the top plate and one side plate; and a third locking portion is formed between the top plate and the other side plate. This allows the bottom surface of the main body to be locked to the top plate side of the roll sheet holder. As a result, the sheet storage box can be stably attached to the roll sheet holder simply by inserting the first locking portion, the second locking portion and the third locking portion around the top plate, excluding the paper cutting portion.

[0008] Furthermore, in the first embodiment, the first locking portion, the second locking portion, and the third locking portion are formed on a part of the bottom surface, allowing the sheet storage box to be directly attached to the roll sheet holder. Therefore, since the sheet storage box can be attached to the roll sheet holder without using a separate component such as an attachment, the attachment of the sheet storage box to the roll sheet holder becomes easier.

[0009] Furthermore, in the first embodiment, the bottom surface of the sheet storage box is locked to the top surface of the roll sheet holder, so that space can be secured for the roll sheet to be installed inside the roll sheet holder when the sheet storage box is attached to the roll sheet holder. Therefore, according to the first embodiment, the sheet storage box and the roll sheet holder can be used interchangeably.

[0010] A second aspect of the present invention provides a sheet storage box according to the first aspect, wherein at least one of the first locking portion, the second locking portion, and the third locking portion has a shape in plan view that tapers from the base end to the tip.

[0011] In the second embodiment, at least one of the first, second, and third locking portions has a shape that tapers from the base to the tip in plan view, making it easier to insert the first, second, and third locking portions into the periphery of the top plate, excluding the paper cutting portion. Therefore, according to the second embodiment, it becomes even easier to attach the sheet storage box to the roll sheet holder.

[0012] A third aspect of the present invention provides a sheet storage box according to the first or second aspect, wherein a tearing line is formed on the bottom surface, and the first locking portion, the second locking portion, and the third locking portion are formed when the tearing line is torn open.

[0013] In the third embodiment, by providing a tearing line on the bottom surface of the main body that, when opened, forms the first locking portion, the second locking portion, and the third locking portion, the first locking portion, the second locking portion, and the third locking portion can be formed only when the sheet storage box is attached to a roll sheet holder.

[0014] A fourth aspect of the present invention provides a sheet storage box according to any one of the first to third aspects, wherein a fold is provided at least one of the base ends of the first locking portion, the second locking portion, and the third locking portion.

[0015] In the fourth aspect, a fold is provided at at least one of the proximal ends of the first locking portion, the second locking portion, and the third locking portion, so that the first locking portion, the second locking portion, and the third locking portion can be easily unfolded through the fold. Therefore, even when the first locking portion, the second locking portion, and the third locking portion are formed as part of the bottom surface, it is easy to attach the sheet storage box to the roll sheet holder.

[0016] A fifth aspect of the present invention provides a sheet storage box according to any one of the first to fourth aspects, wherein the shortest distance from the proximal end to the distal end of the first locking portion is shorter than the length of the proximal end of the second locking portion and the length of the proximal end of the third locking portion.

[0017] In the fifth aspect, by making the shortest distance from the proximal end to the distal end of the first locking portion shorter than the lengths of the proximal ends of the second locking portion and the third locking portion, the opening formed on the bottom surface when the first locking portion, the second locking portion, and the third locking portion formed as part of the bottom surface are unfolded can be reduced. Therefore, according to the fifth aspect, it is difficult for dust to enter the sheet storage box when the sheet storage box is stably attached to the roll sheet holder.

[0018] A sixth aspect of the present invention provides a sheet storage box according to any one of the first to fourth aspects, wherein the first locking portion is arranged at a predetermined interval in a direction in which the long side surface of the main body faces from the edge on the first locking portion side of the second locking portion and the edge on the first locking portion side of the third locking portion. / / 原日文内容中此处的“第1係止部側の端縁”,推测是指靠近第1係止部的边缘,翻译为“the edge on the first locking portion side”

[0019] In the sixth aspect, the first locking portion is arranged at a predetermined interval in a direction in which the long side surface of the main body faces from the edge on the first locking portion side of the second locking portion and the edge on the first locking portion side of the third locking portion. Thus, in a state where the first locking portion is locked between the top plate and the rear plate, the second locking portion and the third locking portion can be locked between the top plate and the side plate so as not to hit the portion where the upper top plate near the rear plate of the side plate is rotatably connected. Therefore, the sheet storage box can be more stably attached to the roll sheet holder.

Advantages of the Invention

[0020] 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 can be used in combination with the roll holder.

[Modes for carrying out the invention]

[0022] 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.

[0023] 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.

[0024] 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. Also, the term "orthogonal" may include substantially orthogonal directions.

[0025] Figure 1 shows a sheet storage box according to an embodiment of the present invention, and Figure 2 shows a sheet stack housed in the sheet storage box. In this embodiment, the sheets S are housed in the main body 10 that constitutes the sheet storage box.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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 / m2 The following applies. In this specification, basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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).

[0035] The material of sheet S is not particularly limited, and for example, sheets of paper, nonwoven fabric, or cloth can be used, and preferably a paper sheet (hereinafter referred to as a paper sheet). The pulp composition can be any known composition for paper sheets. The pulp blending ratio can be, for example, 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

[0036] The pulp composition of the sheet S is not particularly limited. For example, softwood pulps such as NBKP (needle-leaf kraft pulp) and NUKP (needle-leaf unbleached pulp), and hardwood pulps such as LBKP (hardwood kraft pulp) and LUKP (hardwood unbleached pulp) can be used in any ratio.

[0037] 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.

[0038] 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).

[0039] 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.

[0040] The sheet S may be embossed. Such embossing can be carried out by a known embossing method. The embossing method is not particularly limited, and examples include a steel rubber method, a steel match method, etc. Among these, it is preferable to use the steel match method.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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 of multiple sheets (or multiple sets) of sheets S, or a laminate of sheets S in a folded state. 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.

[0045] 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.

[0046] 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.

[0047] An opening 20 is formed on the top surface 11 of the main body 10. The opening 20 is designed so that the sheet S can 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.

[0048] 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.

[0049] 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 OP, which is the outlet 20 (see Figures 1 and 9).

[0050] 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.

[0051] The outlet 20 may be covered with a film material 21, as shown in Figure 9. The material of the film material 21 is not particularly limited, and for example, polyethylene, polypropylene, and other resins can be used. As the resin, biodegradable materials (such as biodegradable plastics like polylactic acid) and biomass materials (renewable organic resources of biological origin, such as biomass film, excluding fossil resources) can be used.

[0052] The shape of the film material 21 is not particularly limited, as long as it covers the outlet 20. In this embodiment, a rectangular film material is used in plan view.

[0053] The thickness of the film material 21 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.

[0054] A slit 22 is formed in the film material 21. The shape of the slit 22 is not particularly limited. In this embodiment, with the film material 21 covering the outlet 20, a linear slit 22 extending in the longitudinal direction (X direction) of the main body 10 is formed in the film material 21. The sheet S removed from the outlet 20 is removed to the outside through the slit 22 of the film material 21 (see Figures 9 and 10).

[0055] The film material 21 is adhered to the back surface of the top surface 11. Specifically, an adhesive portion (not shown) to which the film material 21 is adhered is provided in an overlapping region (not shown) on the back surface of the top surface 11 outside the outlet 20 where the film material 21 overlaps. The film material 21 is adhered to the overlapping region via this adhesive portion.

[0056] 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 21 can be brought into contact with the portion to which the adhesive has been applied. This fixes the film material 21 to the portion to which the adhesive has been applied, and the fixed portion of the film material 21 constitutes the adhesive portion.

[0057] Known adhesives include acrylic-vinyl acetate copolymers and ethylene-vinyl acetate polymer aqueous emulsions.

[0058] Because the film material 21 is adhered to the back surface of the top surface 11, the sheet S removed from the outlet 20 passes through the slit 22 of the film material 21 and does not come into contact with the edge of the outlet 20, thus preventing the sheet S from tearing when removed. 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 slit 22 of the film material 21.

[0059] Furthermore, the dispensing opening 20 may remain open OP without being covered by the film material 21. For example, by placing the film packaging of the sheet laminate SL in a sheet storage box 100 in which the opening OP of the dispensing opening 20 is not covered by the film material 21, 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 21.

[0060] The sheet storage box 100 is used by being attached to the roll sheet holder 90. The roll sheet holder 90 is a holder for attaching and using roll sheets TR such as toilet paper, as shown in Figure 3.

[0061] As shown in Figure 5, the roll sheet holder 90 comprises a rear plate 91, a pair of side plates 92, a top plate 93, and a pair of arms 94.

[0062] 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.

[0063] 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 edge at the end of the top plate 93, allowing it to cut roll sheets TR. The end 93B of the top plate 93 on the rear plate 91 side forms a rotation axis 95 and is connected to the upper part of the side plate 92 closer to the rear plate 91. One side end 93C of the top plate 93 is located on the side plate 92 side, and the other side end 93D is located on the side plate 93 side.

[0064] The arm 94 is attached to the side plate 92 and can rotatably hold a roll of toilet paper.

[0065] The material of the roll sheet holder 90 is not particularly limited and may be resin, metal, etc.

[0066] The sheet storage box 100 of this embodiment is used by being attached to such a roll sheet holder 90. The sheet storage box 100 has a first locking portion 50, a second locking portion 60, and a third locking portion 70. The first locking portion 50, the second locking portion 60, and the third locking portion 70 are formed from a part of the bottom surface 12, as shown in Figure 7.

The sheet storage box 100 of the first embodiment has a first locking part 50, a second locking part 60, and a third locking part 70, as shown in Figure 7.

[0068] The first locking portion 50 is formed on the bottom surface 12 of the main body 10. The first locking portion 50 is locked between the top plate 93 and the rear plate 91 of the roll sheet holder 90. Specifically, as shown in Figures 5 and 8, the first locking portion 50 is inserted and locked between the end portion 93B of the top plate 93 and the rear plate 91. The shape of the first locking portion 50 is not particularly limited. In this embodiment, the shape of the first locking portion 50 is rectangular in plan view.

[0069] The first locking portion 50 is formed in part of the bottom surface 12, as shown in Figure 6. The first locking portion 50 may also be formed by tearing the tearing cut line 30, such as a perforation M1, formed in the bottom surface 12, as shown in Figures 6 and 7. In this embodiment, the first locking portion 50 is formed by tearing the tearing cut lines 31, 32, and 37, which are part of the tearing cut line 30.

[0070] The base end 51 of the first locking portion 50 is formed on the rear (long side 14) side of the bottom surface 12 of the main body 10. A fold 41 may be provided at the base end 51 of the first locking portion 50.

[0071] The second locking portion 60 is formed on the bottom surface 12 of the main body 10. The second locking portion 60 is locked between the top plate 93 and the side plate 92 of the roll sheet holder 90. Specifically, as shown in Figures 5 and 8, the second locking portion 60 is inserted and locked between the side end 93C of the top plate 93 and one of the side plates 92. The shape of the second locking portion 60 is not particularly limited. In this embodiment, the shape of the second locking portion 60 is rectangular in plan view.

[0072] The second locking portion 60 is formed in part of the bottom surface 12, as shown in Figure 6. The second locking portion 60 may also be formed by tearing the tearing cut lines 30, such as perforations M1, formed in the bottom surface 12, as shown in Figures 6 and 7.

[0074] The third locking portion 70 is formed on the bottom surface 12 of the main body 10. The third locking portion 70 is locked between the top plate 93 and the side plate 92 of the roll sheet holder 90. Specifically, as shown in Figures 5 and 8, the third locking portion 70 is inserted and locked between the side end 93D of the top plate 93 and the other side plate 92. The shape of the third locking portion 70 is not particularly limited. In this embodiment, the shape of the third locking portion 70 is rectangular in plan view.

[0075] The third locking portion 70 is formed in part of the bottom surface 12, as shown in Figure 6. The third locking portion 70 may also be formed by tearing the tearing cut lines 30, such as perforations M1, formed in the bottom surface 12, as shown in Figures 6 and 7. In this embodiment, the third locking portion 70 is formed by tearing the tearing cut lines 32, 34, and 36, which are part of the tearing cut lines 30.

[0076] The base end 71 of the third locking portion 70 is formed on the short side 16 of the bottom surface 12 of the main body 10. A fold 43 may be provided at the base end 71 of the third locking portion 70.

[0077] In the first embodiment, as shown in Figure 8, when the splitting line 30 is split, a part of the bottom surface 12 becomes an opening OP1, and a first locking part 50, a second locking part 60, and a third locking part 70 are formed along the edge of the opening OP1. The second locking part 60 and the third locking part 70 are arranged opposite each other in the longitudinal direction of the main body 10.

[0078] Furthermore, from the viewpoint of stably attaching the sheet storage box 100 to the roll sheet holder 90, the distance D1 between the base end 61 of the second locking portion 60 and the base end 71 of the third locking portion 70 is preferably equal to the length T1 of the top plate 93 in the direction in which the pair of side plates 92 of the roll sheet holder 90 face each other (X direction) (see Figures 5 and 7).

[0079] In the first embodiment, as described above, a first locking portion 50 that engages with the rear plate 91, a second locking portion 60 that engages with the top plate 93 and one side plate 92, and a third locking portion 70 that engages with the top plate 93 and the other side plate 92 are formed on the bottom surface 12 of the main body 10, so that the bottom surface 12 of the main body 10 can be locked to the top plate 93 side of the roll sheet holder 90. As a result, the sheet storage box 100 can be stably attached to the roll sheet holder 90 simply by inserting the first locking portion 50, the second locking portion 60 and the third locking portion 70 around the top plate 93, excluding the paper cutting portion 93A.

[0080] Furthermore, in the first embodiment, the first locking portion 50, the second locking portion 60, and the third locking portion 70 are formed from a part of the bottom surface 12 of the main body 10, so that the sheet storage box 100 can be directly attached to the roll sheet holder 90. Therefore, since the sheet storage box 100 can be attached to the roll sheet holder 90 without using a separate component such as an attachment, the attachment of the sheet storage box 100 to the roll sheet holder 90 becomes easier.

[0081] Furthermore, in the first embodiment, the bottom surface 12 of the main body 10 of the sheet storage box 100 is locked to the top plate 93 side of the roll sheet holder 90, so that space can be secured for the roll sheets to be mounted inside the roll sheet holder 90 when the sheet storage box 100 is attached to the roll sheet holder 90. For this reason, according to the first embodiment, the sheet storage box 100 and the roll sheet holder 90 can be used interchangeably.

[0082] In the first embodiment, as described above, by providing a tearing line 30 on the bottom surface 12 of the main body 10, which, when opened, forms the first locking portion 50, the second locking portion 60, and the third locking portion 70, the first locking portion 50, the second locking portion 60, and the third locking portion 70 can be formed only when the sheet storage box 100 is attached to the roll sheet holder 90.

[0083] In the first embodiment, as described above, folds 41, 42, and 43 are provided on at least one of the base ends 51 of the first locking portion 50, the base end 61 of the second locking portion 60, and the base end 71 of the third locking portion 70, making it easier for the first locking portion 50, the second locking portion 60, and the third locking portion 70 to be unfolded via the folds 41, 42, and 43. Therefore, even when the first locking portion 50, the second locking portion 60, and the third locking portion 70 are formed on a part of the bottom surface 12, it becomes easier to attach the sheet storage box 100 to the roll sheet holder 90.

[0084] <Second Embodiment> Figure 11 is a view of the sheet storage box of the second embodiment from the bottom side. Figure 12 is a view of the sheet storage box of the second embodiment with the tearing cut line opened as shown in Figure 11. Figure 13 is a view of the first locking part, second locking part, and third locking part of the sheet storage box of the second embodiment attached to the roll sheet holder. In the second embodiment shown in Figures 11 to 13, parts common to the first embodiment shown in Figures 6 to 8 are denoted by the same or corresponding reference numerals and their descriptions are omitted.

[0085] In the sheet storage box 100 of the second embodiment, as shown in Figure 12, the shortest distance L1 from the base end 51 to the tip 52 of the first locking portion 50 is shorter than the length L2 of the base end 61 of the second locking portion 60 and the length L3 of the base end 71 of the third locking portion 70.

[0086] In the second embodiment, a splitting cut line 37, which is part of the splitting cut line 30, is arranged in a continuous manner with the splitting cut lines 31 and 32, approximately in the center of the width of the bottom surface 12. In the second embodiment, the first locking portion 50 is formed by splitting the splitting cut lines 31, 32, and 37, which are part of the splitting cut line 30. The shortest distance L1 of the formed first locking portion 50 is approximately half the length of the second locking portion 60 L2 and the length of the third locking portion 70 L3.

[0087] The ratio of the shortest distance L1 of the first locking portion 50 to the length L2 of the second locking portion 60 and the length L3 of the third locking portion 70 is preferably 1:5 to 4:5, more preferably 1:4 to 3:4, and even more preferably 1:3 to 2:3.

[0088] In the second embodiment, as shown in Figures 11 to 13, when the splitting cut line 30 is split, a part of the bottom surface 12 becomes an opening OP2, and a first locking portion 50, a second locking portion 60, and a third locking portion 70 are formed along the edge of the opening OP2. The second locking portion 60 and the third locking portion 70 are arranged opposite each other in the longitudinal direction of the main body 10. Furthermore, an extension portion 80 is formed on the long side surface 13 of the opening OP2, extending toward the base end 51 of the first locking portion 50 on the long side surface 14.

[0089] In the second embodiment, by making the shortest distance L1 from the base end 51 to the tip 52 of the first locking portion 50 shorter than the length L2 of the base end 61 of the second locking portion 60 and the length L3 of the base end 71 of the third locking portion 70, the opening OP2 formed on the bottom surface 12 when the first locking portion 50, the second locking portion, and the third locking portion, which are formed in a part of the bottom surface 12, are deployed, can be made smaller. Therefore, in the second embodiment, when the sheet storage box 100 is stably attached to the roll sheet holder 90, dust is less likely to enter the sheet storage box 100.

[0090] <Third Embodiment> Figure 14 is a view of the sheet storage box of the third embodiment from the bottom side. Figure 15 is a view of the sheet storage box of the third embodiment with the tearing cut line opened as shown in Figure 14. Figure 16 is a view of the first locking part, second locking part, and third locking part of the sheet storage box of the third embodiment attached to the roll sheet holder. In the third embodiment shown in Figures 14 to 16, parts common to the first embodiment shown in Figures 6 to 8 are denoted by the same or corresponding reference numerals and their descriptions are omitted.

[0091] In the sheet storage box 100 of the third embodiment, as shown in Figure 15, the first locking portion 50 is positioned with a gap D2 and D3 between it and the edge 63 of the second locking portion 60 on the first locking portion 50 side and the edge 73 of the third locking portion 70 on the first locking portion 50 side, in the direction (Y direction) where the long sides 13 and 14 of the main body 10 face each other.

[0092] In the third embodiment, splitting lines 38 and 39 are formed that extend toward the long side surface 14, respectively, in continuity with splitting lines 31 and 32, which are part of the splitting line 30. In the third embodiment, the first locking portion 50 is formed by splitting the splitting lines 31, 32, 37, 38, and 39, which are part of the splitting line 30. The base end 51 of the formed first locking portion 50 is positioned toward the long side surface 14, relative to the position of the edge 63 of the second locking portion 60 on the first locking portion 50 side and the position of the edge 73 of the third locking portion 70 on the first locking portion 50 side.

[0093] Furthermore, the distances D2 and D3 between the base end 51 of the first locking portion 50 and the end edge 63 of the second locking portion 60 on the first locking portion 50 side and the end edge 73 of the third locking portion 70 on the first locking portion 50 side in the direction (Y direction) where the long sides 13 and 14 face each other are determined such that the ratio of the shortest distance L1 to the length L2 of the second locking portion 60 and the length L3 of the third locking portion 70 is preferably 3:2 to 7:6, more preferably 4:3 to 5:4, and even more preferably 5:4 to 6:5.

[0094] In the third embodiment, as shown in Figures 14 to 16, when the cutting line 30 is cut, a part of the bottom surface 12 becomes an opening OP3, and a first locking part 50, a second locking part 60, and a third locking part 70 are formed along the edge of the opening OP3. The second locking part 60 and the third locking part 70 are arranged opposite each other in the longitudinal direction of the main body 10. Furthermore, a recess 30A is formed on the long side 13 side of the opening OP3, which extends toward the long side 13 side when viewed from above.

[0095] In the third embodiment, the first locking portion 50 is positioned with a predetermined distance D2 and D3 between the end edge 63 of the second locking portion 60 on the side of the first locking portion 50 and the end edge 73 of the third locking portion 70 on the side of the first locking portion 50, in the direction (Y direction) where the long sides 13 and 14 of the main body 10 face each other. With the first locking portion 50 locked between the top plate 93 and the rear plate 91, the second locking portion 60 and the third locking portion 70 can be locked between the top plate 93 and the side plate 92 without contacting the upper part of the side plate 92 near the rear plate 91 where the top plate 93 is rotatably connected. As a result, the sheet storage box 100 can be attached to the roll sheet holder 90 even more stably.

[0096] <Fourth Embodiment> Figure 17 is a view of the sheet storage box of the fourth embodiment from the bottom side. Figure 18 is a view of the sheet storage box of the fourth embodiment with the tearing cut line opened as shown in Figure 17. Figure 19 is a view of the first locking part, second locking part, and third locking part of the sheet storage box of the fourth embodiment attached to the roll sheet holder. In the fourth embodiment shown in Figures 17 to 19, parts common to the first embodiment shown in Figures 6 to 8 are denoted by the same or corresponding reference numerals and their descriptions are omitted.

[0097] In the sheet storage box 100 of the fourth embodiment, as shown in Figures 18 and 19, when the tearing cut line 30 is opened, a part of the bottom surface 12 becomes an opening OP4, and a first locking part 50, a second locking part 60, and a third locking part 70 are formed along the edge of the opening OP4.

[0098] The first locking portion 50 has a shape that tapers from the base end 51 to the tip end 52 when viewed from above. The shape of the first locking portion 50 is not particularly limited. In the fourth embodiment, the shape of the first locking portion 50 is trapezoidal when viewed from above.

[0099] Furthermore, the shape of the second locking portion 60 tapers from the base end 61 to the tip end 62 in a plan view. The shape of the first locking portion 50 is not particularly limited. In the fourth embodiment, the shape of the second locking portion 60 is a roughly right triangle in a plan view. The hypotenuse of the roughly right triangle, which is the shape of the second locking portion 60, corresponds to one of the hypotenuses of the trapezoid, which is the shape of the first locking portion 50.

[0100] Furthermore, the shape of the third locking portion 70 tapers from the base end 71 to the tip end 72 in a plan view. The shape of the third locking portion 70 is not particularly limited. In the fourth embodiment, the shape of the third locking portion 70 is a roughly right triangle in a plan view. The hypotenuse of the roughly right triangle that is the shape of the third locking portion 70 corresponds to the other hypotenuse of the trapezoid that is the shape of the first locking portion 50.

[0101] In the fourth embodiment, at least one of the first locking portion 50, the second locking portion 60, and the third locking portion 70 has a shape in plan view that tapers from each base end (base ends 51, 61, 71) to each tip (tip 52, 62, 72), making it easier to insert the first locking portion 50, the second locking portion 60, and the third locking portion 70 into the periphery of the top plate 93, excluding the paper cutting portion 93A. Therefore, according to the fourth embodiment, it becomes even easier to attach the sheet storage box 100 to the roll sheet holder 90.

[0102] Although not described herein, in the fourth embodiment, the configuration of the third embodiment described above (a configuration in which the first locking portion is arranged at a predetermined distance from the end edge of the second locking portion on the first locking portion side and the end edge of the third locking portion on the first locking portion side of the main body in a direction in which the long side faces each other) may be applied.

[0103] <Fifth Embodiment> Figure 20 is a view of the sheet storage box of the fifth embodiment from the bottom side. Figure 21 is a view of the sheet storage box of the fifth embodiment with the tearing cut line opened as shown in Figure 20. Figure 22 is a view of the first locking part, second locking part, and third locking part of the sheet storage box of the fifth embodiment attached to the roll sheet holder. In the fifth embodiment shown in Figures 20 to 22, parts common to the second embodiment shown in Figures 11 to 13 and the fourth embodiment shown in Figures 17 to 19 are denoted by the same or corresponding reference numerals and their description is omitted.

[0104] In the sheet storage box 100 of the fifth embodiment, as shown in Figures 21 and 22, when the tearing cut line 30 is opened, a part of the bottom surface 12 becomes an opening OP5, and a first locking part 50, a second locking part 60, and a third locking part 70 are formed along the edge of the opening OP5.

[0105] In the fifth embodiment, the shortest distance L1 from the base end 51 to the tip end 52 of the first locking portion 50 is shorter than the length L2 of the base end 61 of the second locking portion 60 and the length L3 of the base end 71 of the third locking portion 70. Furthermore, the first locking portion 50, the second locking portion 60, and the third locking portion 70 all have a shape that tapers from their respective base ends (base ends 51, 61, 71) to their respective tip ends (tip ends 52, 62, 72) when viewed from above.

[0106] In the fifth embodiment, by making the shortest distance L1 from the base end 51 to the tip 52 of the first locking portion 50 shorter than the length L2 of the base end 61 of the second locking portion 60 and the length L3 of the base end 71 of the third locking portion 70, the opening OP2 formed on the bottom surface 12 when the first locking portion 50, the second locking portion, and the third locking portion, which are formed in a part of the bottom surface 12, are unfolded, the opening OP2 formed on the bottom surface 12 can be made smaller. Therefore, in the fifth embodiment, when the sheet storage box 100 is stably attached to the roll sheet holder 90, dust is less likely to enter the sheet storage box 100.

[0107] In the fifth embodiment, at least one of the first locking portion 50, the second locking portion 60, and the third locking portion 70 has a shape in plan view that tapers from each base end (base ends 51, 61, 71) to each tip (tip 52, 62, 72), making it easier to insert the first locking portion 50, the second locking portion 60, and the third locking portion 70 into the periphery of the top plate 93, excluding the paper cutting portion 93A. Therefore, according to the fifth embodiment, it becomes even easier to attach the sheet storage box 100 to the roll sheet holder 90.

[0108] Although not described herein, in the fifth embodiment, the configuration of the third embodiment described above (a configuration in which the first locking portion is arranged at a predetermined distance from the end edge of the second locking portion on the first locking portion side and the end edge of the third locking portion on the first locking portion side of the main body in a direction in which the long side faces each other) may be applied.

[0109] 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]
