Description

Seat storage box

[0001] This disclosure relates to a seat storage box.

[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).

[0003] Japanese Patent Publication No. 2010-22799, Japanese Patent Publication No. 2001-314346, Japanese Patent No. 3511956, Japanese Patent No. 5602531

[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 hooks inside the roll holder, the roll holder and seat storage box cannot be used simultaneously. Also, if a locking piece cut out from a part of the seat storage box is inserted into the gap in 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 disclosure 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.

[0006] A sheet storage box according to one aspect of the present disclosure is a sheet storage box used attached to a roll sheet holder having a top plate whose end is a paper cutting portion, and comprises a rectangular parallelepiped body that houses a sheet stack of a plurality of sheets stacked together, an outlet formed on the top surface of the body from which the sheets are removed, a first opening formed on the bottom surface or one of the long sides of the body, through which the top plate is inserted and locked, and a second opening formed on the bottom surface, through which the paper cutting portion is inserted and locked when the top plate is locked in the first opening.

[0007] According to one aspect of this disclosure, a sheet storage box can be provided that is easy to attach to a roll holder, allows for stable attachment, and can be used in conjunction with a roll holder.

[0009] The embodiments of this disclosure 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.

[0010] 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.

[0011] 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, orthogonal and flush may include substantially orthogonal and substantially flush.

[0012] <Sheet Storage Box> Figure 1 shows a sheet storage box according to an embodiment of the present disclosure, 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.

[0013] 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.

[0014] 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.

[0015] 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). The top surface 11 is an example of the top surface of the sheet storage box of this disclosure.

[0016] 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.

[0017] Furthermore, while there are no restrictions on the basis weight of the base paper, from the perspective of ensuring sufficient strength to withstand use, the basis weight of the base paper is set at 200 g / m². ２ More than 500g / m ２ The following, preferably 230 g / m² ２ 450g / m or more ２ The following, and more preferably 270 g / m² ２ 430g / m or more ２ The following applies. In this specification, basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0018] The thickness of the base paper is not particularly limited, and the paper thickness measured in accordance with the provisions 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.

[0019] 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.

[0020] Furthermore, the width of the main body 10 in the short 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.

[0021] The main body 10 houses a plurality of stacked sheets S. In this embodiment, the plurality of sheets S housed in the main body 10 are composed of a sheet laminate SL in which a plurality of sheets S (a plurality of sheets or a plurality of sets) are stacked in the stacking direction (Z direction, LD direction) (Figures 1 and 2).

[0022] 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.

[0023] The pulp composition of sheet S is not particularly limited. For example, softwood pulp such as NBKP (softwood kraft pulp) or NUKP (unbleached softwood pulp) and hardwood pulp such as LBKP (hardwood kraft pulp) or LUKP (unbleached hardwood pulp) can be used in any ratio.

[0024] The ratio of hardwood pulp to softwood pulp is not limited, but is preferably 10:90 to 80:20, and more preferably, the pulp composition has a higher ratio of hardwood pulp to softwood pulp. Further, wastepaper pulp may be used for the pulp contained in the sheet S.

[0025] Further, 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).

[0026] Further, the thickness of the sheet S is not particularly limited, and the paper thickness measured in accordance with the provisions 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.

[0027] 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 and a steel match method. Among these, it is preferable to use the steel match method.

[0028] The form of the sheet S is not particularly limited, and it can be applied to articles such as toilet paper, tissue paper, paper towel, kitchen paper, baby or nursing paper diapers, and sanitary napkins. Note that sanitary tissue papers such as paper towels and tissue papers include sanitary tissue papers containing a moisturizing component (for example, lotion tissue). Further, the use of the sheet S can be applied to any of industrial, household, and portable uses.

[0029] 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.

[0030] The dimensions of sheet S, for example in the case of toilet paper, are 120-260 mm in length and 80-280 mm in width.

[0031] 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 S or one set at a time, the form of the sheet laminate SL is a pop-up type sheet laminate SL.

[0032] 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 a sheet laminate can be manufactured, for example, by a rotary type or multi-stand type interfolder.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] This lid portion 20A is connected to the top surface 11 via a cleavage cut line M1 such as a perforation. Here, the cleavage cut line is an intermittent cut line in which cuts and ties (uncut portions between two cuts) are alternately arranged, and when a tie breaks, the adjacent cuts become continuous cuts. When using the sheet storage box 100, by cleaving the cleavage cut line M1 and removing the lid portion 20A, an outlet 20 is formed as an opening OP1 (see FIGS. 1 and 9).

[0037] The shape of the outlet 20 is not particularly limited as long as it allows the sheet S housed in the main body 10 to be pulled out from the top surface 11 side. In the present embodiment, the shape of the outlet 20 is elliptical in plan view, but it may be an elongated rectangular shape, a racetrack shape, etc. in plan view.

[0038] As shown in FIG. 9, the outlet 20 may be covered with a film material 21. The material of the film material 21 is not particularly limited, and for example, resins such as polyethylene and polypropylene can be used. In addition, as the resin, biodegradable materials (such as biodegradable plastics like polylactic acid), biomass materials (renewable bio-derived organic resources such as biomass films excluding fossil resources), etc. can be used.

[0039] The shape of the film material 21 is not particularly limited as long as it covers the outlet 20. In the present embodiment, a rectangular film material in plan view is used.

[0040] The thickness of the film material 21 is not particularly limited, and for example, it is 10 μm or more and 50 μm or less, preferably 15 μm or more and 45 μm or less, more preferably 20 μm or more and 40 μm or less.

[0041] A slit 22 is formed in the film material 21. The shape of the slit 22 is not particularly limited. In the present embodiment, a linear slit 22 extending in the longitudinal direction (X direction) of the main body 10 is formed in the film material 21 in a state where the film material 21 covers the outlet 20. The sheet S taken out from the outlet 20 is taken out to the outside through the slit 22 of the film material 21 (see FIGS. 9 and 10).

[0042] The film material 21 is adhered to the back surface of the top surface 11. Specifically, an adhesion part (not shown) to which the film material 21 is adhered is provided in a superimposed region (not shown) where the film material 21 overlaps outside the take-out port 20 on the back surface of the top surface 11. The film material 21 is adhered to the superimposed region through this adhesion part.

[0043] The mode of the adhesion part is not particularly limited. For example, a known adhesive is previously applied to a portion corresponding to the superimposed region on the back surface of the top surface 11, and the film material 21 is brought into contact with the portion where the adhesive is applied. Thereby, the film material 21 is fixed to the portion where the adhesive is applied, and the fixed portion of the film material 21 constitutes the adhesion part.

[0044] Examples of the known adhesive include an acrylic / vinyl acetate copolymer, an ethylene / vinyl acetate polymer aqueous emulsion, and the like.

[0045] Since such a film material 21 is adhered to the back surface of the top surface 11, the sheet S taken out from the take-out port 20 passes through the slit 22 of the film material 21 and does not contact the edge of the take-out port 20, so that it is possible to prevent the sheet S from being torn when taken out. Further, since the next sheet S is locked to the slit 22 of the film material 21 when the sheet S is taken out, the sheet laminate SL can be used in a pop-up manner.

[0046] Note that the take-out port 20 may remain as the opening OP1 without being covered by the film material 21. For example, by accommodating the film package of the sheet laminate SL in the sheet storage box 100 in which the opening OP1 of the take-out port 20 is not covered by the film material 21, the sheet laminate SL can be used in a pop-up manner even if the take-out port 20 is not covered by the film material 21.

[0047] The sheet storage box 100 is attached to and used with the roll sheet holder 90. The roll sheet holder 90 is a holder for mounting and using a roll sheet TR such as a roll of toilet paper shown in FIG. 3.

[0048] As shown in Figures 3 to 5, the roll sheet holder 90 comprises a rear plate 91, a pair of side plates 92, a top plate 93, and a hook 94.

[0049] 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.

[0050] The top plate 93 is rotatably connected to the rear plate 91, and the end opposite to the rear plate 91 forms a paper cutting section 93A. The paper cutting section 93A has a curved end at the top plate 93, allowing it to cut roll sheets TR.

[0051] The hook 94 is attached to the side plate 92 and can rotatably secure a roll of toilet paper.

[0052] The material of the roll sheet holder 90 is not particularly limited and may be resin, metal, etc.

[0053] The sheet storage box 100 of this embodiment is attached to such a roll sheet holder 90 and further has a first opening 30 and a second opening 40.

[0054] <First Embodiment> Figure 6 is a view of the sheet storage box of the first embodiment from the bottom side. Figure 7 is a view of the state after the tearing cut line in Figure 6 has been opened. Figure 8 is a view of the state in which the top plate of the roll sheet holder has been inserted through the first opening and the second opening of the main body of the sheet storage box of the first embodiment.

[0055] In the sheet storage box 100 of the first embodiment, as shown in Figures 6 and 7, a first opening 30 is formed in the bottom surface 12 of the main body 10. As shown in Figure 8, the top plate 93 of the roll sheet holder 90 is inserted into and locked through the first opening 30. The first opening 30 may also be formed as an opening OP2 by tearing along a perforation line M2, as shown in Figures 6 and 7.

[0056] The shape of the first opening 30 is not particularly limited, but it is preferably a shape that extends in the longitudinal direction (X direction) of the main body 10 with a first length L1, and further preferably a shape that extends in the longitudinal direction (X direction) of the main body 10 with a first width W1 in the short direction (Y direction) of the main body 10. Furthermore, it is preferable that the first length L1 is longer than 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 to 7).

[0057] In the first embodiment, the shape of the first opening 30 is rectangular in plan view, but it may also be elliptical, racetrack-shaped, or the like.

[0058] The position of the first opening 30 is not particularly limited, but when it is formed on the bottom surface 12 of the main body 10 as in the first embodiment, it is preferably located on one of the long sides 14 of the main body 10. In the first embodiment, as shown in Figures 6 and 7, the first opening 30 is located on the long side 14 that constitutes the back surface of the main body 10.

[0059] In the sheet storage box 100 of the first embodiment, as shown in Figures 6 and 7, a second opening 40 is formed in the bottom surface 12 of the main body 10. As shown in Figure 8, the paper cutting portion 93A of the top plate 93 of the roll sheet holder 90 is inserted into the second opening 40 when the top plate 93 of the roll sheet holder 90 is locked in the first opening 30. The second opening 40 may also be formed as an opening OP3 by tearing along a tearing line M3, such as a perforation, as shown in Figures 6 and 7.

[0060] The shape of the second opening 40 is not particularly limited, but it is preferably a shape that extends in the longitudinal direction (X direction) of the main body 10 with a second length L2, and further preferably a shape that extends in the longitudinal direction (X direction) of the main body 10 with a second width W2 in the short direction (Y direction) of the main body 10 (see Figures 5 to 7).

[0061] In the first embodiment, the shape of the second opening 40 is rectangular in plan view, but it may also be elliptical, racetrack-shaped, or the like.

[0062] The position of the second opening 40 is not particularly limited, but when the second opening 40 is formed on the bottom surface 12 as in the first embodiment, it is preferably located on the other long side surface 13 of the main body 10. In the first embodiment, as shown in Figures 6 and 7, the second opening 40 is located on the long side surface 13 that constitutes the front surface of the main body 10, parallel to the first opening 30 in the short direction (Y direction) of the main body 10.

[0063] In the sheet storage box 100 of the first embodiment, as shown in Figures 5 and 7, it is preferable that the second length L2 is longer than the length T1 of the top plate 93 in the direction (X direction) where the pair of side plates 92 of the roll sheet holder 90 face each other. Also, as shown in Figures 6 and 7, it is preferable that the first width W1 of the first opening 30 is greater than the second width W2 of the second opening 40.

[0064] In the first embodiment, as described above, the top plate 93 of the roll sheet holder 90 is inserted and locked into a first opening 30 formed in the bottom surface 12 of the main body 10 of the sheet storage box 100, and the paper cutting portion 93A of the top plate 93 is inserted and locked into a second opening 40 formed in the bottom surface 12. As a result, the bottom surface 12 of the main body 10 is fixed to the top plate 93 of the roll sheet holder 90, so that the sheet storage box 100 can be stably attached to the roll sheet holder 90.

[0065] Furthermore, in the first 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 first embodiment, the attachment of the sheet storage box 100 to the roll sheet holder 90 becomes easier.

[0066] Furthermore, in the first embodiment, the bottom surface 12 of the main body 10 of the sheet storage box 100 is fixed to the top plate 93 of the roll sheet holder 90, so that space can be secured for the roll sheet TR 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 in combination (see Figures 8, 9, and 10).

[0067] In the first embodiment, as described above, the first length L1 of the first opening 30 and the second length L2 of the second opening 40, which extend in the longitudinal direction (X direction) of the main body 10 of the sheet storage box 100, are longer than the length T1 of the top plate 93 in the direction (X direction) in which the pair of side plates 92 of the roll sheet holder 90 face each other, making it easier to insert the top plate 93 of the roll sheet holder 90 into the first opening 30 and the second opening 40 of the main body 10 of the sheet storage box 100 (see Figures 3 to 8).

[0068] In the first embodiment, as described above, the first width W1 of the first opening 30 extending in the longitudinal direction (X direction) of the main body 10 of the sheet storage box 100 is greater than the second width W2 of the second opening 40, which facilitates the insertion of the top plate 93 of the roll sheet holder 90 into the first opening 30 of the main body 10 of the sheet storage box 100. Furthermore, the paper cutting portion 93A of the top plate 93 of the roll sheet holder 90 can be securely locked into the second opening 40 of the main body 10 of the sheet storage box 100. In addition, the positioning of the first opening 30 and the second opening 40 extending in the longitudinal direction (X direction) of the main body 10 becomes easier.

[0069] In the first embodiment, as described above, the first opening 30 formed on the bottom surface 12 of the main body 10 of the sheet storage box 100 is located on one of the long sides 14 of the main body 10, so that the back surface (long side 14) of the main body 10 and the back surface (rear plate 91) of the roll sheet holder 90 can be made flush. As a result, the sheet storage box 100 can be attached to the roll sheet holder 90 more stably.

[0070] In the first embodiment, as described above, by providing tearing lines M2 and M3 that, when slit, form a first opening 30 and / or a second opening 40, the first opening 30 and / or the second opening 40 can be formed only when the sheet storage box 100 is to be used attached to the roll sheet holder 90.

[0071] <Second Embodiment> Figure 11 is a view of the sheet storage box of the second embodiment from one long side. Figure 12 is a view of the sheet storage box of the second embodiment from the bottom side. Figure 13 is a view of the sheet storage box of the second embodiment with the tearing line opened as shown in Figure 11. Figure 14 is a view of the sheet storage box of the second embodiment with the tearing line opened as shown in Figure 12. In the second embodiment shown in Figures 11 to 14, 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.

[0072] In the sheet storage box 100 of the second embodiment, as shown in Figures 11 and 13, a first opening 60 is formed on the long side surface 14 of the main body 10. As shown in Figure 15, the top plate 93 of the roll sheet holder 90 is inserted into and locked through the first opening 60. The first opening 60 may also be formed as an opening OP4 by tearing along a perforation line M4, as shown in Figures 11 and 13.

[0073] The shape of the first opening 60 is not particularly limited, but it is preferably a shape that extends in the longitudinal direction (X direction) of the main body 10 with a first length L3, and further preferably a shape that extends in the longitudinal direction (X direction) of the main body 10 with a third width W3 in the short direction (Y direction) of the main body 10. Furthermore, it is preferable that the first length L3 is longer than 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 13).

[0074] In the second embodiment, the shape of the first opening 60 is rectangular in plan view, but it may also be elliptical, racetrack-shaped, or the like.

[0075] The position of the first opening 60 is not particularly limited, but when it is formed on one of the long sides 14 of the main body 10, as in the second embodiment, it is preferably located adjacent to the bottom surface 12 of the main body 10. In the second embodiment, as shown in Figures 11 and 12, the first opening 60 is formed along the edge 12A of the bottom surface 12 of the main body 10.

[0076] In the sheet storage box 100 of the second embodiment, as shown in Figures 12 and 14, a second opening 50 is formed in the bottom surface 12 of the main body 10. As shown in Figure 15, the paper cutting portion 93A of the top plate 93 of the roll sheet holder 90 is inserted into the second opening 50 when the top plate 93 of the roll sheet holder 90 is locked in the first opening 60. The second opening 50 may also be formed as an opening OP5 by tearing along a tearing line M5 such as a perforation, as shown in Figures 12 and 14.

[0077] The shape of the second opening 50 is not particularly limited, but it is preferably a shape that extends in the longitudinal direction (X direction) of the main body 10 with a second length L4, and further preferably an extension in the longitudinal direction (X direction) of the main body 10 with a fourth width W4 in the short direction (Y direction) of the main body 10. Furthermore, it is preferable that the second length L4 is longer than 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 13).

[0078] In the second embodiment, the shape of the second opening 50 is rectangular in plan view, but it may also be elliptical, racetrack-shaped, or the like.

[0079] The position of the second opening 50 is not particularly limited, but when the second opening 50 is formed on the bottom surface 12 of the main body 10, as in the second embodiment, it is preferably located between one of the long sides 14 of the main body 10 and the approximate center. In the second embodiment, as shown in Figures 12 and 14, the second opening 50 is located approximately in the center of the bottom surface 12 of the main body 10.
