Description

  The present invention relates to a sheet storage body, and in particular, a plurality of sheet materials each having a scraping surface having a friction coefficient larger than that of the other surface are stacked and stored, and can be taken out one by one from a take-out opening. It is related with the sheet storage body.

  For example, various sheet storage bodies have been proposed in which a plurality of sheet materials such as wet tissue are stacked and stored, and can be taken out one by one from the take-out opening. In such a sheet storage body, depending on the size, shape, application, material, etc. of the sheet material to be stored, it is easy to take out each sheet material, easy to use after each sheet material is taken out, or compact. Various devices have been devised in the folded shape of the sheet material, the laminating method, and the like so as to obtain an efficient storage form and the like (see, for example, Patent Document 1 and Patent Document 2).

For example, in the package described in Patent Document 1, the sheet material is folded into a Z shape including a mountain fold and a valley fold, and a part of the folded portion is sandwiched between the folded portions of the next sheet material to be alternately stacked. Thus, the bulkiness is made uniform as a whole, and it is possible to stack with an appropriate contact area, and when the sheet material is taken out, the end of the next sheet material jumps out from the takeout opening of the sheet container. Thus, it is easy to take out the sheet material superimposed on the top and bottom. In addition, in the package described in Patent Document 2, the sheet material is crumpled even when the sheet material having a large area is folded in multiple layers and accommodated in a small package in a stacked state by devising the folded shape of the sheet material. Without being done, it can be easily taken out from the take-out opening of the sheet container in a folded state.

  On the other hand, in recent years, for example, as a sheet material having an excellent scraping effect that can remove persistent stains around water such as around kitchens, bathrooms, and washstands, for example, the sheath has a core-sheath structure containing abrasive particles. An abrasive nonwoven sheet using composite fibers has been developed. Further, a cleaning sheet has been developed that includes a large-diameter thermoplastic fiber having a fiber length of 2 to 15 mm and a stasis of 10 to 150 dtex, and has a large number of tip portions of the large-diameter thermoplastic fiber on the surface (for example, patents). Reference 3). Furthermore, in the sheet material having an excellent scraping effect on the surface to be cleaned, for example, a liquid holding sheet that holds the liquid agent is joined to the back surface side to form a two-layer structure, so that one surface is more than the other surface. May have a scraping surface with a large coefficient of friction.

  However, since the sheet material with excellent scraping effect on the surface to be cleaned has a large coefficient of friction on the scraping surface, a part of the folded part folded in the Z shape is sandwiched between the folded parts of the next sheet material and laminated. If it does, the friction of a Z-shaped overlapping part and the friction of the part which pinched | interposed the bending part will become large too much, and it will become difficult to take out each sheet material from an opening. In addition, when multiple folding is performed, not only the folding process is complicated, but also when the sheet is taken out from the take-out opening, friction when opened from the folded state becomes excessively large, and it becomes difficult to take out each sheet material. Therefore, it is desired to develop a new sheet storage body that can efficiently store in a laminated state sheet materials that have a scraping surface having a friction coefficient larger than that of the other surface while ensuring ease of removal. ing.

  The present invention provides a sheet storage body that can efficiently store a plurality of sheet materials in which one surface is a scraping surface having a larger coefficient of friction than the other surface in a stacked state while ensuring ease of taking out. For the purpose.

  The present invention is a sheet storage body in which a plurality of sheet materials each having a scraping surface having a friction coefficient larger than that of the other surface are stacked and stored, and can be taken out one by one from the extraction opening. Each of the sheet materials has a portion on the one end side such that the other side faces the inner side and one end side is arranged at a central portion between the folding line and the other end side. By folding back as a folded portion and being folded in two, it has a sheet double region and a sheet single region with the one end as a boundary, and the folded portion is disposed on the take-out opening side and the one side The sheet material is accommodated by stacking the sheet double region and the sheet single region alternately so as to overlap each other for each unit number. Providing a seat container More, in which to achieve the above objects.

  According to the sheet storage body of the present invention, a plurality of sheet materials in which one surface is a scraping surface having a higher friction coefficient than the other surface are efficiently stored in a stacked state while ensuring ease of taking out. be able to.

  As shown in FIGS. 1 (a), 1 (b) and FIGS. 2 (a) to (c), a sheet storage body 10 according to a preferred embodiment of the present invention is used as a sheet material, for example, around a kitchen, a bathroom, and a bathroom. For example, a plurality of cleaning sheets 11 that are preferably used for scraping and cleaning dirt around water such as a table are stacked and stored in a package 12 formed of a synthetic resin laminated film including an aluminum foil layer, for example. It is a thing. In the sheet storage body 10 of the present embodiment, a cleaning sheet 11 suitable for scraping cleaning has a scraping surface 11a with one surface having a larger coefficient of friction than the other surface, and is folded or stacked. When the large friction by the scraping surface 11 a acts between the surfaces of the cleaning sheets 11 that overlap, it becomes difficult to take out the cleaning sheets 11 from the take-out opening 13 of the package 12. The sheet storage body 10 of the present embodiment is efficient in a stacked state while ensuring ease of taking out the plurality of cleaning sheets 11 having one surface that is a scraping surface 11a having a larger friction coefficient than the other surface. It was adopted so that it could be stored.

  The sheet storage body 10 of the present embodiment stacks and stores a plurality of cleaning sheets 11 in which one surface 11a becomes a scraping surface 11a having a larger friction coefficient than the other surface 11b. It is a storage body by pillow packaging that can be taken out one by one from the take-out opening 13, and each cleaning sheet 11 has the other surface 11b inside, and one end side 14a is the folding line 15 and the other end side. 14b by folding the portion on the one end side 14a side as a folded portion 16 so as to be arranged at the center between the end portion 14b (see FIG. 2 (b)). The sheet double region 17a and the sheet single region 17b are provided, the folded portion 16 is disposed on the extraction opening 13 side, one end side 14a is disposed across the opening 13, and the unit number In a sheet double region 17a and the sheet singlet region 17b are laminated so as to overlap alternately, the cleaning sheet 11 is a plurality housed in package 12.

  In the present embodiment, the sheet double region 17 a and the sheet single region 17 b are stacked so as to alternately overlap each other, and a plurality of cleaning sheets 11 are stored in the package 12.

  In this embodiment, the packaging body 12 that stores a plurality of cleaning sheets 11 is a laminate in which a film having heat sealability is laminated on, for example, a polyethylene terephthalate (PET) film deposited with aluminum, silica, or alumina. It is formed using a film. That is, the packaging body 12 arrange | positions the film which has heat-sealability inside the packaging body 12, wraps the some cleaning sheet 11 of the laminated | stacked state, and heat-seal-joins a laminated | multilayer film to the vertical direction and a horizontal direction. Thus, a plurality of cleaning sheets 11 are accommodated, for example, formed as a pillow package having finished dimensions of a flat rectangular shape having a length of 190 mm, a width of 128 mm, and a thickness of 22 mm (see FIG. 1). Moreover, in this embodiment, the package body 12 has lateral end portions 18a and 18b having a width of, for example, about 10 to 25 mm at both ends in the longitudinal direction, and a central portion of one lateral direction seal portion 18a. A hanging hole 19 is formed in the through hole. Further, a substantially oval shaped extraction opening 13 having a width of about 15 to 45 mm and a length of about 25 to 85 mm, for example, is formed at the center of the upper surface of the package 12. Further, a tuck label 20 with a knob made of a laminated film made of the same material as that of the package 12 is attached as a resealable lid that can be opened and closed so as to cover the take-out opening 13.

  As shown in FIGS. 3A to 3C, the cleaning sheet 11 accommodated in the package 12 is preferably a sheet material having an excellent scraping effect on the surface to be cleaned, for example, JP-A-2003-61885. Can be used. In the sheet material described in JP-A-2003-61885, an airlaid nonwoven fabric 22 containing large-diameter thermoplastic fibers is laminated on one side of a liquid-holding sheet 21 containing cellulosic fibers, and the liquid-holding sheet 21 and This is a sheet material having a two-layer structure in which an airlaid nonwoven fabric 22 is integrated.

  Here, the air laid nonwoven fabric 22 constitutes the scraping surface 11a which is one surface 11a of the cleaning sheet 11, and as a resin fiber thicker than the fiber constituting the other surface 11b, for example, the fiber length is 2 to 2. It is formed by containing 10 to 90% by weight of a large-diameter thermoplastic fiber 23 having a diameter of 15 mm and a fineness of 10 to 150 dtex. As a result, the scraped surface 11a of the air laid nonwoven fabric 22 has a large number of tip portions of the large-diameter thermoplastic fiber 23 having a short fiber length (2 to 15 mm) and a large fineness (10 to 150 dtex). This makes it difficult for the fibers 23 to bend, and increases the polishing and scraping properties of the dirt 25 present on the surface to be cleaned 24 (see FIG. 3C).

  Moreover, the liquid retention sheet | seat 21 comprises the other surface 11b of the cleaning sheet 11, and is formed including 30-100 weight% of cellulose fibers, for example, Preferably 50-100 weight%. Moreover, there is no restriction | limiting in particular about the fineness of the cellulose fiber contained in the liquid holding sheet 21, The thing of a suitable fineness can be used according to the kind of cellulose fiber. The fiber length of the cellulosic fibers contained in the liquid-holding sheet 21 is appropriately selected according to the method for manufacturing the liquid-holding sheet 21. For example, when the liquid retaining sheet 21 is produced by a wet papermaking method, the fiber length of the cellulosic fiber 3 is preferably 0.1 to 20 mm, particularly preferably 0.2 to 15 mm. Moreover, when the liquid retaining sheet 21 is manufactured by the spunlace method or the thermal bond method, the fiber length of the cellulosic fiber 3 is preferably 30 to 100 mm, particularly preferably 35 to 65 mm. Furthermore, when the liquid retaining sheet 21 is manufactured by the air array method, the fiber length of the cellulosic fiber 3 is preferably 0.1 to 15 mm, particularly preferably 0.3 to 10 mm. The liquid retaining sheet 21 can be appropriately impregnated with a liquid agent such as a cleaning agent.

  In the present embodiment, the liquid retaining sheet 21 and the airlaid nonwoven fabric 22 are joined and integrated by, for example, fusion using heat embossing or ultrasonic embossing or adhesion using a hot melt adhesive, whereby the cleaning sheet 11 is formed. The Thus, preferably, the static friction coefficient between the one surfaces 11a of the cleaning sheet 11 by the air laid nonwoven fabric 22 is 0.8 to 1.5, and the static friction coefficient between the other surfaces 11b by the liquid retaining sheet 21 is one of the surfaces. A value smaller than the surface 11a is 0.6 to 1.0. Here, the coefficient of static friction between the surfaces 11a and 11b of the cleaning sheet 11 is a value obtained in accordance with ASTM D1894.

  In the present embodiment, the cleaning sheet 11 can be used as a dry sheet not impregnated with liquid and as a wet sheet impregnated or coated with a liquid agent such as an aqueous cleaning agent, and particularly impregnated or coated with a liquid agent such as an aqueous cleaning agent. It is effective to use. Since the cleaning sheet 11 includes the cellulose fiber having hydrophilicity in the liquid holding sheet 21, it is possible to hold a sufficient amount of liquid agent for cleaning. When the cleaning sheet 11 is used as a wet sheet impregnated with a liquid agent, in addition to mechanically polishing or scraping off the dirt on the surface to be cleaned, the liquid swells or partially dissolves the dirt. Therefore, the removal property of dirt by mechanical polishing or scraping action is further improved. When used as a wet sheet, the cleaning sheet 11 may be preliminarily impregnated with the liquid agent, or the liquid sheet is applied to the dry cleaning sheet 11 and the cleaning sheet 11 coated with the liquid agent is used for cleaning. The surface may be cleaned.

  In addition, as a liquid agent such as an aqueous cleaning agent that is impregnated or used in combination with the cleaning sheet 11, it is preferable to use, for example, water as a medium and a surfactant, an alkaline agent, an electrolyte, and a water-soluble solvent. Furthermore, it is preferable to contain a disinfectant. The nonvolatile residual component contained in the liquid agent is preferably 10% by weight or less from the viewpoint of finish after cleaning, and particularly preferably 5% by weight or less.

  And in this embodiment, the cleaning sheet 11 provided with the above-mentioned structure is formed in the rectangular shape of 70-200 mm square, for example, and as shown to Fig.2 (a)-(c), the other surface 11b is set inside. Then, the portion on the one end side 14a side is folded back as a folded portion 16 and folded in two, and the sheet double region 17a and the sheet single region 17b are preferably laminated so as to alternately overlap each other. By storing a plurality of the cleaning sheets 11 in the packaging body 12 in the state, the sheet storage body 10 is formed (see FIG. 1A).

  That is, for example, the cleaning sheet 11 formed in a rectangular planar shape having a size of about 155 mm in length and about 125 mm in width is divided into three in the vertical direction, and the other surface 11b of the liquid holding sheet 21 is set on one side, A sheet double region 17a in which the air-laid nonwoven fabric 22 is exposed on the upper surface side and a liquid retaining sheet 21 on the upper surface side are formed by folding the 1/3 region on the side 14a side through the folding line 15 as the folded portion 16. The double-folded cleaning sheet 11 is formed in which the exposed sheet single region 17b is disposed on both sides with one end side 14a as a boundary. Then, the cleaning sheet 11 folded in half is disposed with the folded portion 16 on the upper surface side disposed on the take-out opening 13 side of the packaging body 12 and one sheet double region 17a and one sheet single region 17b. By stacking eight sheets, for example, in a state where they are alternately stacked one by one (see FIG. 2 (c)), as described above, they are stored so as to be wrapped in a package 12 made of a laminated film. The sheet storage body 10 of the embodiment is formed. In addition, by this, one end side 14a arranged at the center of the upper surface side of the stacked cleaning sheets 11 crosses the extraction opening 13 formed in the upper surface central portion of the package 12 so that the extraction is performed. It is disposed at the center of the opening 13.

  And according to the sheet storage body 10 of this embodiment, while ensuring ease of taking out the plurality of cleaning sheets 11 in which the one surface 11a becomes the scraping surface 11a having a larger friction coefficient than the other surface 11b. It becomes possible to store efficiently in the laminated state.

  That is, according to the present embodiment, each cleaning sheet 11 to be laminated has the other surface 11b having a small friction coefficient inside, and one end side 14a is between the folding line 15 and the other end side 14b. The folded portion 16 is folded and folded in two so as to be arranged at the center. Therefore, each cleaning sheet 11 folded in half has one surface 11a having a large friction coefficient disposed on the outside, and the one surface 11a does not overlap each other. In addition, even between the cleaning sheets 11 that are adjacent to each other in the vertical direction, the area where the surfaces 11 a having a large friction coefficient overlap each other is small, and the end of the cleaning sheet 11 to be taken out is between the next cleaning sheets 11. It is not caught. Accordingly, it is possible to reduce the frictional resistance caused by the one surface 11a having a large friction coefficient, and to smoothly take out each cleaning sheet 11 in an opened state. Then, when the cleaning sheet 11 is picked from the takeout opening 13 with its end portion being picked, the one surface 11a having a large friction coefficient moves in a direction away from the next sheet. The frictional resistance between the surface 11a and the one surface 11a of the next sheet can be reduced, and the cleaning sheet 11 can be taken out smoothly.

  Further, according to the present embodiment, since the end portion of the cleaning sheet 11 to be taken out is not sandwiched between the next cleaning sheets 11, the next cleaning sheet 11 does not jump out from the take-out opening 13. However, since one end side 14a and one surface 11a having a large friction coefficient face the take-out opening 13, the ease of picking up the cleaning sheet 11 is maintained at the time of take-out, and each cleaning sheet 11 can be opened. It becomes possible to take it out smoothly.

  Furthermore, according to the present embodiment, the sheet double region 17a and the sheet single region 17b are stacked so as to alternately overlap every unit number (one sheet in the present embodiment) inside the packaging body 12, Since a plurality of cleaning sheets 11 are stored, the thicknesses of the cleaning sheets 11 to be stacked can be made substantially uniform throughout and the plurality of sheet materials 11 can be efficiently stored in the package 12.

  Furthermore, according to the present embodiment, the end portion of the cleaning sheet 11 next to the cleaning sheet 11 to be taken out is prevented from jumping out from the take-out opening 13, so that the take-out opening 13 can be resealed by the tack label 20. For example, when the cleaning sheet 11 is impregnated with a liquid agent, the cleaning sheet 11 can be effectively prevented from drying.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, it is not always necessary to store a plurality of sheet materials by alternately stacking and storing sheet double regions and sheet single regions one by one. You can also In addition, other various sheet materials other than the cleaning sheet, which have a scraped surface on one side, can be folded in half, and the package for storing the laminated sheet material is a pillow made of a laminated film. In addition to the package, other various packages having a take-out opening may be used.
