[0009] At least the following points will become apparent from the description of this specification and the accompanying drawings. Aspect 1 is a container for disposable absorbent sanitary products, characterized in having a disposable absorbent sanitary product that absorbs bodily fluids, a container member that contains the disposable absorbent sanitary product, and a sheet material that contains a fatty acid salt as a cleaning agent.

[0010] According to the first aspect, even if the hands become dirty when replacing the absorbent sanitary product, the sheet material containing the fatty acid salt can be used as hand-washing soap to clean the hands after replacing the absorbent sanitary product.

[0011] A second aspect is a container for a disposable absorbent sanitary product according to the first aspect, wherein the sheet material is water-decomposable or water-soluble.

[0012] According to the second aspect, since the sheet material is water-degradable or water-soluble, it can be flushed down the toilet as it is when used for washing hands. It can also be used for flushing the toilet by flushing it down the toilet. This can also reduce the amount of waste to be disposed of in appropriate places such as waste bins and trash cans.

[0013] A third aspect is the container for the disposable absorbent sanitary product according to the first or second aspect, wherein the sheet material comprises a substrate having water-decomposability or water-solubility.

[0014] According to the third aspect, the strength of the sheet material is increased by providing the substrate, making the sheet material less likely to tear during processing, use, and storage, and improving processability and storage properties.

[0015] A fourth aspect is the container for the disposable absorbent sanitary product according to the first or second aspect, wherein the sheet material does not include a substrate.

[0016] According to the fourth aspect, since the sheet material does not have a substrate, it dissolves quickly in water when washing hands or flushing down a toilet, preventing clogging of pipes. In addition, the cost of the substrate can be reduced.

[0017] Aspect 5 is a container for a disposable absorbent sanitary product described in any of Aspects 1 to 4, wherein the disposable absorbent sanitary product includes an absorbent body and a packaging sheet that individually packages the absorbent body, and in the disposable absorbent sanitary product in a state packaged by the packaging sheet, the sheet material is provided inside the packaging sheet.

[0018] According to the fifth aspect, since the sheet material is located inside the packaging sheet, the sheet material is not touched until the absorbent sanitary product in a packaged state (so-called individual package) is opened, and the sheet material can be prevented from being damaged. In addition, in the case of a water-decomposable or water-soluble sheet material, the sheet material can be prevented from dissolving before use. In addition, since most disposable absorbent sanitary products having an absorbent main body are usually replaced in the toilet by the user himself, the sheet material can be flushed down the toilet immediately after replacement. In addition, even if the user gets his hands dirty during replacement, the sheet material can be used to wash his hands at the washbasin immediately after replacement.

[0019] Aspect 6 is a container for a disposable absorbent sanitary product according to aspect 5, wherein the absorbent body has an adhesive portion for attaching the absorbent body to underwear during use, the disposable absorbent sanitary product has a separator placed on the surface of the adhesive portion, and the sheet material is the separator.

[0020] According to the sixth aspect, the separator is a portion that is peeled off and discarded after use, and by using a sheet material in such a portion, the sheet material can be easily used for washing hands or flushing the toilet.

[0021] A seventh aspect is a container for a disposable absorbent sanitary product according to the sixth aspect, wherein the separator is fixed to the packaging sheet and is separable from the packaging sheet.

[0022] According to the seventh aspect, since the separator is separable, after replacement, the wrapping sheet portion can be discarded together with the used absorbent body, while the separated separator can be easily used for washing hands or flushing the toilet.

[0023] In aspect 8, the disposable absorbent sanitary product is a container for a disposable absorbent sanitary product described in any of aspects 1 to 4, wherein the disposable absorbent sanitary product includes an absorbent body and a packaging sheet that individually packages the absorbent body, and the sheet material is the packaging sheet.

[0024] According to the eighth aspect, the packaging sheet is a portion that is discarded after use, and by using a sheet material in such a portion, the sheet material can be easily used for washing hands or flushing the toilet.

[0025] Aspect 9 is a container for a disposable absorbent sanitary product described in any of Aspects 1 to 4, wherein the disposable absorbent sanitary product has a lead tape for fastening an opening, and the sheet material is the lead tape.

[0026] According to the ninth aspect, the lead tape is a portion that is discarded after use, and by using the sheet material in such a portion, the sheet material becomes easy to use for washing hands or flushing a toilet.

[0027] A tenth aspect is a container for a disposable absorbent sanitary product according to any one of the first to fourth aspects, wherein the sheet material forms at least a part of the container member.

[0028] According to the tenth aspect, the portion of the container member that is made of a sheet material can be used for washing hands or flushing the toilet.

[0029] Aspect 11 is a container for a disposable absorbent sanitary product described in any of Aspects 2 to 5, wherein the disposable absorbent sanitary product has an absorbent body that is water-decomposable or water-soluble, the absorbent body having a liquid-absorbing absorbent core, a top sheet arranged on the skin side of the absorbent core, and a back sheet arranged on the non-skin side of the absorbent core, and the sheet material is the back sheet.

[0030] According to aspect 11, since the absorbent body is water-decomposable or water-soluble, the absorbent body itself can be flushed down the toilet after use, and by using the sheet material as the back sheet, a toilet cleaning effect can be achieved when flushed.

[0031] Aspect 12 is a container for a disposable absorbent sanitary product described in any one of Aspects 1 to 11, wherein the sheet material contains powder and the powder forms unevenness on the surface of the sheet material.

[0032] According to the twelfth aspect, when the sheet material is used for washing hands, the unevenness makes it easy for the sheet material to be caught by the hands, and the powder exerts a so-called scrubbing effect, thereby enhancing the washing effect.

[0033] A thirteenth aspect of the present invention is a container for a disposable absorbent sanitary product according to any one of the first to twelfth aspects, wherein the sheet material has optical transparency.

[0034] According to the thirteenth aspect, the inside can be seen from the outside through the sheet material, and the pattern, product shape, absorption state, etc. applied inside the sheet material can be seen.

[0035] A fourteenth aspect is a container for a disposable absorbent sanitary product according to any one of the first to thirteenth aspects, wherein the sheet material has a plurality of compressed portions.

[0037] Aspect 15 is a container for a disposable absorbent sanitary product described in any one of aspects 1 to 14, wherein the sheet material is provided with a fragrance, and the fragrance emits a stronger scent after getting wet with water than before getting wet with water.

[0038] According to the fifteenth aspect, the fragrance is retained in the sheet material by the fragrance, and the fragrance is released stronger after it is wet than before it is wet, so that the fragrance can be made to last longer. This not only makes the fragrance more likely to remain after washing hands with the sheet material, but also makes the fragrance more likely to remain in the toilet when the sheet material is flushed down the toilet.

[0039] A sixteenth aspect is a container for a disposable absorbent sanitary product according to any one of the first to fifteenth aspects, wherein the sheet material is colored.

[0040] According to the sixteenth aspect, the sheet material is colored, so that the sheet material can be easily seen when used for washing hands. In addition, if the sheet material is water-decomposable or water-soluble, it becomes easy to see how the sheet material is being decomposed or dissolved.

[0041] A seventeenth aspect is a container for a disposable absorbent sanitary product according to any one of the first to sixteenth aspects, wherein the sheet material changes color before and after getting wet with water.

[0042] According to the seventeenth aspect, the sheet material can be easily seen when it is used for washing hands. In addition, when the sheet material is water-decomposable or water-soluble, it becomes easy to see how the sheet material is being decomposed or dissolved.

[0043] === Implementation form === Hereinafter, an embodiment of the present invention will be described by taking a sanitary napkin container as an example of a container for a disposable absorbent sanitary product, but the disposable absorbent sanitary product is not limited to sanitary napkins, and includes products that absorb body fluids (menstrual blood, urine, sweat, feces, breast milk, blood, exudate, saliva, etc.) and maintain hygiene. For example, in addition to sanitary napkins, disposable sanitary products include disposable sanitary products that are fixed to the user's clothing, such as panty liners, light incontinence pads, and absorbent pads, as well as sanitary tampons, paper diapers, breast milk pads, underarm sweat pads, disposable masks, disposable diapers for pets, absorbent pads for pets, and waste disposal sheets.

[0044] <Disposable absorbent sanitary product container 100> FIG. 1 is a perspective view of a container 100. As shown in FIG. 1, the container 100 (also referred to as a "container for disposable absorbent sanitary products") has a plurality of sanitary napkins (disposable absorbent sanitary products) 1 and a container member 101 that contains the sanitary napkins 1 (hereinafter also simply referred to as "napkins 1"). The container 100 has a vertical direction, a horizontal direction, and a front-rear direction that are perpendicular to each other. In this embodiment, 16 napkins 1 are contained in one container 100, but the number of napkins 1 contained is not limited to this. An opening 102 for removing the napkins 1 is provided on the upper surface of the container member 101. The opening 102 is a cut line formed by a plurality of slits along the horizontal direction, and when removing the napkins 1 from the container 100, the opening 102 can be opened along the cut line to remove the napkins 1.

[0045] Furthermore, the container 100 (container member 101) of this embodiment may have a transparent or semi-transparent window 103 on the front surface. The window 103 may be configured so that the napkins 1 inside can be visually confirmed from the outside of the container 100.

[0046] 1, in this embodiment, the container 100 in which the napkin 1 is contained in the container member 101 is a substantially hexahedron having multiple faces, but is not limited thereto and may be another polyhedron. Also, the container 100 may be in a form in which the napkin 1 is contained in the container member 101 formed in a bag shape.

[0047] <Basic composition of Napkin 1> FIG. 2 is a plan view of the napkin 1 in an unfolded state, as viewed from the skin side. FIG. 3A is a plan view of the absorbent main body 10 of the napkin 1, as viewed from the skin side in the thickness direction, and FIG. 3B is a plan view of the absorbent main body 10 of the napkin 1, as viewed from the non-skin side in the thickness direction. FIG. 4 is a schematic cross-sectional view of the absorbent main body 10 as viewed from the arrow AA in FIG. 3A. FIG. 5A is a diagram explaining a state in which the wing parts 10W of the absorbent main body 10 are folded inward in the left-right direction in the napkin 1 in an unfolded state, and FIG. 5B is a plan view of the napkin 1 in the state of FIG. 5A, as viewed from the non-skin side. FIG. 6 is a diagram explaining a state in which the napkin 1 is folded at the second fold line F2 from the state of FIG. 5A. FIG. 7 is a diagram of the napkin 1 in a packaged state, as viewed from the lead tape 21 side.

[0048] The napkin 1 in the unfolded state has a longitudinal direction, a left-right direction, and a thickness direction that are perpendicular to each other. As shown in FIG. 2, the napkin 1 has an absorbent body 10 and a packaging sheet 20 that individually packages the absorbent body 10. A lead tape 21 is provided on the end of the packaging sheet 20 that is located on the front side of the absorbent body 10 in the unfolded state. A central separator 35 (FIG. 5B) is provided between the absorbent body 10 and the packaging sheet 20 in the thickness direction. As shown in FIG. 2, the napkin 1 in the unfolded state has the packaging sheet 20 shown in FIG. 5A, FIG. 5B, FIG. 6, etc., the central separator 35, and the absorbent body 10 shown in FIG. 3A and FIG. 3B, which are stacked in this order from the non-skin side.

[0049] The napkin 1 in the "unfolded state" refers to a state in which the napkin 1 in the packaged state is opened and all the folded parts are unfolded as shown in Fig. 2. The napkin 150 in the "wrapped state" refers to a state in which the napkin 1 in the unfolded state is sealed by folding a pair of wing parts (wing parts 10W, 10W described later) inward in the left-right direction, folding the top sheet (top sheet 12 described later) inward at a first fold line F1 and a second fold line F2, welding the end 20e in the left-right direction of the packaging sheet 20, and fastening the opening of the napkin 1 with the lead tape 21. When opening, the wearer first grasps the lead tape 21 and unfolds the napkin 1 by pulling the lead tape 21. The napkin 1 has two fold lines, a first fold line F1 and a second fold line F2. The first fold line F1 is the fold line that is unfolded first to change from a wrapped state to an unfolded state, and the second fold line F2 is the fold line that is unfolded last to change from a wrapped state to an unfolded state.

[0050] <Absorbent body 10> As shown in Figures 3A, 3B and 4, the absorbent body 10 has a longitudinal direction, a width direction and a thickness direction which are perpendicular to each other. In the longitudinal direction of the absorbent body 10, the side which contacts the lower abdomen of the user is called the "front side", and the side which contacts the buttocks of the user is called the "rear side". In the thickness direction of the absorbent body 10, the side which contacts the skin of the user is called the "skin side", and the opposite side is called the "non-skin side" (Figure 4). The longitudinal direction of the absorbent body 10 is also the longitudinal direction of the napkin 1 in the unfolded state. Line XX in the figure is the center line in the left-right direction.

[0051] The absorbent body 10 has a top sheet 12, an absorbent core 15, a back sheet 14, and a side sheet 16. As shown in FIG. 4, in the left-right central portion of the absorbent body 10, the top sheet 12, the absorbent core 15, and the back sheet 14 are laminated in order from the skin side in the thickness direction, and the side sheet 16 is arranged from the left-right end of the skin side of the top sheet 12 to the left-right end of the non-skin side of the absorbent core 15. The top sheet 12, the absorbent core 15, the back sheet 14, and the side sheet 16 are each bonded and fixed using an adhesive such as a hot melt adhesive. The adhesive is applied in an arbitrary application pattern over the skin side and non-skin side of each member, and can be selected from application patterns such as an Ω pattern, a spiral pattern, and a stripe pattern. For convenience, the adhesive is omitted in FIG. 4 and other drawings.

[0052] The top sheet 12 is a liquid-permeable sheet member, and an example of such a sheet is an air-through nonwoven fabric. The side sheets 16 are each a hydrophobic sheet member, and an example of such a sheet is an air-through nonwoven fabric or a spunbond nonwoven fabric. The back sheet 14 is a liquid-impermeable sheet member, and an example of such a sheet is a polyethylene (PE) resin film. The back sheet 14 has a planar size larger than that of the absorbent core 15, and covers the entire planar surface of the absorbent core 15.

[0053] The absorbent main body 10 also has a pair of wing portions 10W extending outward in the left and right direction from the center in the longitudinal direction. The wing portions 10W are formed by side sheets 16 and a back sheet 14 extending outward from both left and right sides of the top sheet 12, etc. Note that the absorbent main body 10 may have a configuration that does not include the wing portions 10W.

[0054] The absorbent core 15 is a member that absorbs and retains bodily waste inside. The absorbent core 15 also has a cover sheet (not shown) that covers the absorbent core 15. The absorbent core 15 is formed into a predetermined shape by adding liquid-absorbent fibers such as pulp fibers or cellulosic absorbent fibers to liquid-absorbent granular materials such as superabsorbent polymers (so-called SAP). The cover sheet is a liquid-permeable sheet, and an example of the cover sheet is tissue.

[0055] The non-skin side of the absorbent main body 10 (i.e., the non-skin side of the back sheet 14) is provided with a central adhesive portion (adhesive portion) 18, which is formed by applying an adhesive or the like. As shown in Fig. 3B, the central adhesive portions 18 are rectangular in shape with long sides in the longitudinal direction and are arranged at intervals in the left-right direction, but the shape, number, and arrangement of the central adhesive portions 18 are not limited to this. When the absorbent main body 10 is used, the central adhesive portion 18 is attached to the skin side of clothing such as underwear, thereby fixing the absorbent main body 10 to the underwear, etc.

[0056] Similarly, a wing adhesive portion (adhesive portion) 19 is provided on the non-skin side (non-skin side of the back sheet 14) of each wing portion 10W in the thickness direction. The shape, number, and arrangement of the wing adhesive portions 19 are not limited to the form shown in Fig. 3B. When using the absorbent main body 10, the wing portions 10W are folded toward the non-skin side, and the wing adhesive portions 19 are attached to the non-skin side of underwear or the like. In this way, the wing portions 10W are fixed to the underwear or the like.

[0057] Although the basic configuration of the absorbent body 10 has been described above, the above-mentioned configuration of the absorbent body 10 is one example and is not limited thereto. For example, in the absorbent body 10, a liquid-permeable intermediate sheet may be provided between the top sheet 12 and the absorbent core 15.

[0058] <About the packaging sheet 20> The packaging sheet 20 is a sheet member that individually packages the absorbent main body 10 and is a member that is removed when using the absorbent main body 10. The packaging sheet 20 is formed from a nonwoven fabric, a film laminated with a nonwoven fabric, or the like. The packaging sheet 20 may also be formed from various films, such as a plastic film, a nylon film, or the like.

[0059] Before use, as shown in Fig. 5B, the central adhesive portion 18 is covered by the central separator 35. As shown in Fig. 5A, the wing adhesive portion 19 is covered by the wing separator 30 when the wing portion 10W is folded inward in the left-right direction. Note that, in this embodiment, the central separator 35 is provided between the packaging sheet 20 and the central adhesive portion 18, but this is not limiting. For example, the central separator 35 may not be provided and the central adhesive portion 18 may be covered by the packaging sheet.

[0060] A release treatment is applied to the surface of the central separator 35 facing the central adhesive portion 18, so that the central separator 35 and the central adhesive portion 18 can be separated from each other. The wing separator 30 is also configured so as to be separable from the wing adhesive portion 19, but details of the wing separator 30 will be described later.

[0061] 5B, the central separator 35 and the packaging sheet 20 are fixed by the respective fixing parts 45, and during use, the central separator 35 is removed from the absorbent main body 10 together with the packaging sheet 20. Moreover, since the wing separators 30 are not fixed to the packaging sheet 20, they are removed from the absorbent main body 10 separately from the packaging sheet 20.

[0062] As shown in Fig. 1, in the napkin 1, the absorbent body 10 is fixed to the inner surface of the packaging sheet 20 with its skin side facing up via the central separator 35. Then, as shown in Fig. 5A, the pair of wing parts 10W are folded back inwards in the left-right direction, and the wing separator 30 is fixed to the wing adhesive part 19. In this state, the packaging sheet 20 and the absorbent body 10 are folded at the second fold line F2 (Fig. 6), and then folded at the first fold line F1. The packaging sheets 20 are sealed together at the end 20e on the left-right outer side of the absorbent body 10, and the opening of the napkin 1 is secured with the lead tape 21, resulting in an individually packaged state (wrapped state) (see Fig. 7). In this embodiment, the napkin 1 is provided with the lead tape 21 for the user to hold when opening, but the lead tape 21 may not be provided.

[0063] As described above, the sanitary napkin 1 of this embodiment has been described, but usually, when a user replaces such an absorbent sanitary product for sanitary use, the used absorbent sanitary product has absorbed bodily fluids (menstrual blood), and the user's hands may become dirty when replacing it. In addition, when using absorbent sanitary products that absorb bodily fluids (urine, sweat, feces, breast milk, blood, exudate, saliva, etc.), not limited to absorbent sanitary products for sanitary use, the used absorbent sanitary product has absorbed the bodily fluids, and so the bodily fluids may adhere to the user's hands when replacing it, and the user may need to wash their hands.

[0064] In this regard, the napkin 1 stored in the storage body 100 of this embodiment has a sheet material containing a fatty acid salt as a detergent, and specifically, the wing separator 30 placed on the surface of the wing adhesive portion 19 of the absorbent body 10 is a sheet material containing a fatty acid salt as the detergent. The wing separator 30 (sheet material) can be separated from the napkin 1 during use, and even if the hands become dirty when changing the napkin 1, the wing separator 30, which is a sheet material containing a fatty acid salt as a detergent, can be used as hand-washing soap to clean the hands after changing the napkin 1.

[0065] The "fatty acid salt as a cleaning agent" preferably contains a higher fatty acid salt having a large number of carbon atoms. The "sheet material containing a fatty acid salt" is a sheet material in which the functional agent mainly contains a fatty acid salt, and the mass ratio of the fatty acid salt in the sheet material is preferably 30% or more.

[0066] Moreover, the wing separator 30 (sheet material) is preferably water-disintegrable or water-soluble. Here, water-disintegrable means that when the sheet material is put into a large amount of water, its strength decreases and it is decomposed by the force of the water flow or the like so as not to retain its original shape, and the degree of water-disintegrability is preferably such that the time it takes for the sheet material to easily become disintegrated (water disintegration time) measured in accordance with JIS P 4501 is less than 100 seconds. Moreover, water-solubility in the present invention means that 5 g or more of the material dissolves in 100 g of water at 20°C.

[0067] In this way, since the wing separator 30 (sheet material) is water-decomposable or water-soluble, when the wing separator 30 is used to wash hands at a washbasin after changing the napkin 1, the wing separator 30 can be used as soap and flushed away as it is. Also, sanitary absorbent products for menstruation, such as the napkin 1, are usually products that the user himself / herself replaces in the toilet. Therefore, if the wing separator 30 is separable from the napkin 1 and is water-decomposable or water-soluble, after replacement, the parts other than the wing separator 30 can be discarded together with the used absorbent main body 10, and the separated wing separator 30 can be promptly flushed down the toilet when replacing, so that the sheet material can also be used for flushing the toilet. Also, by flushing down the toilet in this way, the amount of waste to be disposed of in appropriate places such as waste bins and trash cans can be reduced.

[0068] If the wing separator 30 (sheet material) does not have sufficient water-disintegrability or water-solubility, the wing separator 30 is used to wash hands at a washroom and then discarded in a trash can or the like.

[0069] In this embodiment, the sheet material (wing separator 30) does not have a substrate. An example of the components and manufacturing method of such a substrate-free "sheet material containing a fatty acid salt as a cleaning agent" will be described below. The soap ingredients used were potassium myristate, sodium myristate, and sodium laurate, glycerin as a softener, hydroxypropyl methylcellulose (HPMC) as a thickener, polysorbate 80 as an emulsifier, and etidronic acid as a stabilizer, and coloring agents and fragrances were also added. <Production method> 1) Preparation: Add the weighed ingredients to the water and mix. 2) Coating: The prepared solution is applied onto the base film. 3) Drying: After coating, the coating is placed in a drying oven and dried while adjusting the moisture content. 4) Slitting: Cut to size as needed. Preferably, the sheet material has a basis weight of 55 g / m 2 , and the density is 1.14g / cc.

[0070] As described above, the sheet material (wing separator 30) does not have a base material, so that it dissolves quickly in water when used for washing hands or when flushed down a toilet, and it is possible to prevent clogging of pipes. In addition, by not having a base material, it is possible to reduce the cost of the base material.

[0071] In addition, in this embodiment, a sheet material (wing separator 30) without a substrate is used, but the present invention is not limited thereto, and the sheet material may have a substrate having water-disintegrability or water-solubility. Examples of the substrate include water-disintegrable paper, water-disintegrable nonwoven fabric, PVA film, and the like. When the sheet material has such a substrate, the strength of the sheet material is increased, and the sheet material is less likely to tear during processing, use, and storage, improving processability and storage properties.

[0072] In this embodiment, the above-mentioned "sheet material containing fatty acid salt as a cleaning agent" is used as the wing separator 30, but in a packaged absorbent sanitary product such as the napkin 1 of this embodiment, which is packaged with the packaging sheet 20, the sheet material is preferably provided inside the packaging sheet 20. By providing the sheet material inside the packaging sheet 20, the user does not touch the sheet material until opening the packaged napkin 1 (so-called individual package), and damage to the sheet material can be prevented. In addition, if the sheet agent is water-degradable or water-soluble, providing the sheet material inside the packaging sheet 20 can prevent the sheet material from dissolving before use.

[0073] In this embodiment, a sheet material containing a fatty acid salt as the above-mentioned cleansing agent is used as the wing separator 30, but the sheet material may be the central separator 35 placed on the surface of the central adhesive portion 18. The central separator 35 is a portion that is peeled off and discarded after use, similar to the wing separator 30, and by using the sheet material in such a portion, for example, the central separator 35 can be used for washing hands or flushing a toilet after being configured to be separable from the packaging sheet 20. Even if the central separator 35 is not in a form that can be separated from the packaging sheet 20 as in this embodiment, since the central separator 35 is only fixed to the packaging sheet 20 by the fixing portions 45 at three locations, after replacing the napkin 1, the central separator 35, which is a sheet material, can be partially separated from the packaging sheet 20 by hand, and the separated central separator 35 can be used for washing hands or flushing a toilet.

[0074] Furthermore, the sheet material containing the fatty acid salt as the above-mentioned cleansing agent used as the wing separator 30 in this embodiment may be, for example, the packaging sheet 20. The packaging sheet 20 is a portion that is discarded when the napkin 1 is used, and by using the sheet material in such a portion, the packaging sheet 20 can be easily used for washing hands and cleaning the toilet. Furthermore, since the soap component contained in the sheet material provides good releasability, when the sheet material is used as the packaging sheet 20, the central separator 35 is not necessary, and costs such as material costs can be reduced.

[0075] Furthermore, because of the good releasability, in the present embodiment as well, there is no need to perform a release treatment on the surface of the wing separator 30 (sheet material) on the wing adhesive portion 19 side, which allows for cost reduction.

[0076] Furthermore, the sheet material containing the fatty acid salt as the above-mentioned cleansing agent in this embodiment may be, for example, the lead tape 21. Similarly, the lead tape 21 is a portion that is discarded when the napkin 1 is used, and by using the sheet material in such a portion, it becomes easier for the user to separate the lead tape 21 from the packaging sheet 20 after replacing the napkin 1 and use the lead tape 21 for washing hands or flushing the toilet.

[0077] In this embodiment, the wing separator 30 (sheet material) may contain a powder, and the powder may form irregularities on the surface of the wing separator 30 (sheet material). Examples of the powder that can be used include crystalline cellulose, cyclodextrin, and calcium carbonate. By forming irregularities on the surface of the wing separator 30 (sheet material) with such a powder, when the wing separator 30 (sheet material) is used for washing hands, the irregularities prevent the sheet material from slipping, making it easier for the sheet material to catch on the hands, and the powder exerts a so-called scrubbing effect to enhance the washing effect.

[0078] In addition, the sheet material containing the fatty acid salt as a cleaning agent used as the wing separator 30 in this embodiment may have optical transparency. By having optical transparency, it becomes easier to see the inside through the sheet material. For example, as described above, when the sheet material is used as the packaging sheet 20 for packaging the napkin 1, the central separator 35 is not provided. Therefore, for example, when a design such as a predetermined pattern is applied to the non-skin side of the back sheet 14, such a design or product shape applied on the inside of the packaging sheet 20 can be seen through the packaging sheet 20.

[0079] Furthermore, the sheet material containing fatty acid salt as a cleaning agent used as the wing separator 30 in this embodiment may have multiple compressed parts. By having multiple compressed parts in the wing separator 30 (sheet material), when the wing separator 30 (sheet material) is used for washing hands, the compressed parts can be easily caught by the hands, improving the cleaning effect. Furthermore, since the compressed parts have high transparency, when the wing separator 30 (sheet material) is configured to form a design such as a predetermined pattern, the visibility of the design can also be improved.

[0080] In addition, the sheet material containing fatty acid salt as a cleaning agent used as the wing separator 30 in this embodiment may be provided with a fragrance, and it is desirable that the fragrance releases a stronger fragrance after it is wetted with water than before it is wetted with water. Examples of the fragrance include fragrances in which the fragrance is encapsulated in cyclodextrin and fragrances adsorbed on porous materials. Such fragrances suppress the release of fragrance in a dry state, while releasing a stronger fragrance after it is wetted with water than before it is wetted with water, thereby increasing the persistence of the fragrance. In addition, this not only makes it easier for the fragrance to remain after washing hands with the sheet material, but also makes it easier for the fragrance to remain in the toilet when the sheet material is flushed down the toilet. Furthermore, although the sheet material emits a stronger scent after it gets wet from use such as washing hands, the scent is retained in the sheet material even when it is dry. Therefore, by disposing of the wing separator 30 (sheet material) in a container for storing used sanitary products such as napkins 1 (a so-called waste bin) or in a trash can, it can be used as an air freshener or to deodorize the trash can.

[0081] In addition, the sheet material containing the fatty acid salt as the cleaning agent used as the wing separator 30 in this embodiment may be colored. By coloring the wing separator 30 (sheet material), the sheet material can be easily seen when the wing separator 30 (sheet material) is used for washing hands after changing the napkin 1. In addition, if the wing separator 30 (sheet material) is water-decomposable or water-soluble, for example, when the wing separator 30 (sheet material) is used for flushing the toilet, the wastewater is colored, making it easy to see how the wing separator 30 (sheet material) is decomposing or dissolving.

[0082] Furthermore, the sheet material containing the fatty acid salt as the cleaning agent used as the wing separator 30 in this embodiment may be a sheet material whose color changes before and after it is wetted with water. Such a change in color makes it possible to make the wing separator 30 (sheet material) easier to see when using the wing separator 30 (sheet material) to wash hands after changing the napkin 1. Furthermore, if the wing separator 30 (sheet material) is water-decomposable or water-soluble, for example, when the wing separator 30 (sheet material) is flushed down the toilet, it becomes easier to see how the wing separator 30 (sheet material) is decomposing or dissolving.

[0083] ===Other=== The above-mentioned embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.

[0084] In the above-described embodiment, the sheet material containing a fatty acid salt as a cleansing agent is used as the wing separator 30, and the case where it is used in another part of the napkin 1 has also been exemplified, but the present invention is not limited to this. For example, the sheet material containing the fatty acid salt may form at least a part of the storage member 101 of the storage body 100. An example of at least a part of the storage member 101 is the window portion 103 in the storage member 101 of the above-described embodiment. When the sheet material is used as the window portion 103, the window portion 103, which is a part of the storage member 101 formed from the sheet material, is removed by hand, and the user can use the window portion 103 to wash his / her hands or flush the toilet.

[0085] In the above embodiment, the sheet material containing the fatty acid salt as a cleansing agent is used as the wing separator 30, but is not limited thereto. For example, in a napkin 1 (disposable absorbent sanitary product), when the absorbent body 10 is water-decomposable or water-soluble, a sheet material containing the fatty acid salt as a cleansing agent may be used as the back sheet 14. Since the absorbent body 10 is water-decomposable or water-soluble, the absorbent body 10 itself can be flushed down the toilet after use, and by using the sheet material as the back sheet 14 of the absorbent body 10 having such a configuration, a toilet cleaning effect can be exhibited when flushed down the toilet.
