Detailed Description

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.

An absorbent article container comprising: an absorbent article; and a housing member that houses the absorbent article, the housing member including an outermost layer and an innermost layer, at least a part of the outermost layer being formed of paper, at least a part of the innermost layer being formed of a low-moisture-permeability material having a moisture permeability lower than that of the paper, a mass ratio of the paper constituting the outermost layer being more than 50% of a mass of the housing member.

According to such an absorbent article housing, in addition to paper, a layer formed of a material having lower moisture permeability than that of paper is provided inside, which makes it possible to suppress entry of moisture into the inside of the housing member and ensure excellent moisture resistance. Further, since the mass ratio of the paper exceeds 50%, this makes the paper a main material of the housing member. The housing member can be regarded as having a reference mark that can be discarded as waste paper, which makes it possible to provide an environmentally friendly housing body.

In such an absorbent article housing, it is desirable that the absorbent article housing has a vertical direction, a horizontal direction, and a front-rear direction intersecting each other, the housing member includes a bottom seal portion located in both end portions in the horizontal direction and joined along the vertical direction, and a pair of side seal portions located in lower end portions in the vertical direction and joined along the horizontal direction, and in the pair of side seal portions and the bottom seal portion, the following low moisture permeability materials are welded adjacent to each other in the front-rear direction: the low moisture permeability material provided in an innermost layer constituting one surface of the housing member; and the low moisture permeability material of the innermost layer disposed on a surface different from the one surface.

According to such an absorbent article housing, in all the seal portions of the housing member, the low moisture permeability materials provided on the innermost layer are welded to each other, which makes it less likely that moisture enters the housing.

In such an absorbent article housing, it is desirable that the absorbent article housing further includes an opening for taking out the absorbent article, and that the opening has a sealing portion that can be opened and closed.

According to the absorbent article housing body, even after the housing body has been once opened, the sealing portion can reseal the housing member at each use, which makes it possible to prevent moisture from entering.

In such an absorbent article housing, it is desirable that the absorbent article housing has a vertical direction, a horizontal direction, and a front-rear direction intersecting each other, the outermost layer is provided on an upper side and a lower side of the sealing portion in the vertical direction, and the low moisture permeability material included in the innermost layer is provided on the upper side and the lower side of the sealing portion in the vertical direction.

According to the absorbent article housing, the portion on the upper side of the sealing portion is a portion to be gripped when opening the housing member, and in such an upper side portion, a low moisture permeability material and an outermost layer are provided so that the grip portion is less likely to be torn.

In such an absorbent article housing, it is desirable that the material having low moisture permeability is a resin sheet.

According to the absorbent article housing, the resin sheet is included in at least a part of the innermost layer as a material having low moisture permeability, which makes it possible to provide a housing less likely to absorb moisture.

In such an absorbent article housing, it is desirable that the housing member includes a window region which is a region at least a part of which is formed only of a resin sheet, and a non-window region which is a region where the paper and the resin sheet overlap, and a surface area of the window region is smaller than a surface area of the non-window region.

According to such an absorbent article housing, the absorbent articles in the housing can be inspected through the window area, and minimizing the window area makes it possible to reduce the possibility of moisture entering the interior of the housing member.

In such an absorbent article housing, it is desirable that the absorbent article housing has a vertical direction, a lateral direction, and a front-rear direction intersecting each other, and that the window region is provided continuously from one end of the lateral direction to the other end of the lateral direction along the lateral direction.

According to the absorbent article housing, since the window area is provided up to the end in the width direction (left-right direction), it is made easier for the consumer to visually recognize the absorbent article located inside without opening the housing, which makes it possible to reduce the opening frequency for confirmation or the like. Thus, this makes it possible to reduce the possibility of moisture entering the inside of the housing.

In such an absorbent article housing, it is desirable that a pattern is provided on the outermost layer, and the pattern is formed of an aqueous ink.

According to the absorbent article housing, the use of the aqueous ink makes it possible to reduce the amount of the petroleum-derived organic solvent used, as compared with the case of forming an image using the oily ink. Thus, this makes it possible to realize a more environmentally friendly housing.

In such an absorbent article housing, it is desirable that a pattern is provided on at least a part of the outermost surface of the absorbent article, and the maximum density of the pattern provided on the outermost layer of the housing member is higher than the maximum density of the pattern provided on the outermost surface of the absorbent article.

According to the absorbent article housing, the graphics provided on the outermost surface of the absorbent article become inconspicuous with respect to the graphics provided on the outermost layer of the housing member. That is, the graphic of the absorbent article is less likely to be visually recognized from the outside of the receiving member. This makes it possible to further enhance the visibility of the graphics provided on the housing member side, and enables the user to easily recognize that the housing member is an environmentally friendly product formed of paper.

< Basic Structure of absorbent article storage body 1 >

An embodiment of an absorbent article housing according to the present invention is described below by way of an example of a disposable diaper housing 1 (hereinafter, also simply referred to as "housing 1") housing a disposable diaper. However, the absorbent article housed in the housing body 1 is not limited to disposable diapers, and is applicable to sanitary napkins, pads, light incontinence pads, and the like that can be housed in a housing member.

Fig. 1 is a front view and a cross-sectional view of the housing 1. The housing 1 includes: a housing member 10 as a bag-like member; and a plurality of absorbent articles 20 (disposable diapers) accommodated in the accommodation member 10. The housing 1 (housing member 10) has a vertical direction, a horizontal direction, and a front-rear direction intersecting each other. The front view of fig. 1 shows the housing body 1 seen from the front side in the front-rear direction, and the cross-sectional view of fig. 1 shows a cross section taken along a line A-A of the front view. Further, fig. 1 shows a state in which the housing body 1 stands upright and the lower end of the housing body 1 is in contact with the ground plane.

As shown in fig. 1, the housing member 10 has a housing space (a region indicated by a hatched portion in a cross section taken along a line A-A of fig. 1) having a substantially triangular cross-sectional shape whose width increases in the front-rear direction as going from one side (upper side in fig. 1) toward the other side (lower side in fig. 1) in the up-down direction. In the receiving space, one or more absorbent articles 20 may be received. The plurality of absorbent articles 20 (4 in fig. 1) are housed so as to be stacked in the front-rear direction, and are freely placed in and taken out of an opening 10pn (described later), and the opening 10pn is formed on one side (upper side) in the vertical direction of the housing member 10.

(Containing Member 10)

Fig. 2A is a plan view of the housing member 10 seen from the front side, and fig. 2B is a plan view of the housing member 10 seen from the rear side. Fig. 3A is a schematic cross-sectional view showing a cross section taken along a line B-B of fig. 2A, and fig. 3B is a schematic cross-sectional view showing a cross section taken along a line C-C of fig. 2A.

In the present embodiment, the housing member 10 has a front surface 11, a rear surface 12, and a bottom surface 13. Further, as shown in fig. 3A and 3B, the housing member 10 includes: an outermost layer 10a constituting an outer surface of the housing member 10; and an innermost layer 10b constituting an inner surface. More specifically, the front surface 11, the rear surface 12, and the bottom surface 13 of the housing member 10 have a double-layer structure in which the outermost layer 10a and the innermost layer 10b are bonded to each other. However, the front surface 11, the rear surface 12, and the bottom surface 13 may have three or more layers, or some of the front surface 11, the rear surface 12, and the bottom surface 13 may have a single-layer structure.

At least a part of the outermost layer 10a of the housing member 10 is formed of paper. Here, "paper" is paper manufactured by gluing plant fibers or the like. In the present embodiment, it is desirable that the paper constituting the outermost layer 10a is "paper" formed of plant fibers such as pulp fibers. Although the housing member 10 is formed of a composite material using a material other than paper, it is desirable that the proportion of the mass of paper constituting the outermost layer 10a exceeds 50% of the mass of the housing member 10. By so doing, even when the housing member 10 is formed of a composite material, the mass ratio of the paper exceeds 50%, which makes the paper the main material of the housing member 10. The housing member 10 can be regarded as having a reference mark (not shown, so-called "paper" mark) that can be discarded as waste paper. In the case where the housing member 10 (housing body 1) is provided with a "paper" mark, the housing member 10 is an object that can be collected when discarded from each household. This enables the user to recognize that the housing body 1 is manufactured environmentally friendly. It should be noted that the definition of "paper" where a "paper" label can be applied is a material made by combining and gluing "vegetable fibers". However, even if the paper has a "paper" mark due to the mixing of materials other than vegetable fibers, this makes it easy for the user to recognize that the housing 1 is a so-called "reduced-profile" product in which the amount of petroleum-based material is reduced, since the outermost layer 10a is formed of a paper material. This makes it possible to give the user a visual impression of environmental protection. Therefore, in the present embodiment, it is desirable that the outermost layer 10a is formed entirely of paper.

Further, in the front surface 11 of the housing member 10, a predetermined pattern 15 may be provided on the surface of the front surface side (front side in the front-rear direction) of the outermost layer 10 a. The graphic 15 is provided so that the user visually recognizes various information related to the container 1 (absorbent article 20). In the present embodiment, as shown in fig. 2A, information related to the name (product name) or characteristics (used material) of the absorbent article 20, a picture (for example, a cotton graphic) for inducing imagination of the absorbent article 20, the size of the target wearer, and the like is provided as the graphic 15. Further, as the graphic 15, various authentication marks (not shown) may be provided.

The graphic 15 is printed on the front surface side of the outermost layer 10a by gravure printing or flexography with a predetermined aqueous ink. Generally, for an aqueous ink, water is used as a solvent in many cases, and thus the aqueous ink is an environmentally friendly ink because it is safe and has little odor as compared with an oily ink using an organic solvent or the like. Meanwhile, the fixing property of the aqueous ink to the printing medium is weak as compared with the oily ink, and therefore, in some cases, it is difficult to use the aqueous ink for a product to be circulated to the market. In contrast, in the present embodiment, since the outermost layer 10a as a printing medium is formed of paper, aqueous ink is easily fixed, so that the pattern 15 can be stably formed. Therefore, from the viewpoint of environmental considerations, it is also suitable to use an aqueous ink as the ink for printing the graphics 15 on the housing member 10 of the present embodiment.

At least a part of the innermost layer 10b is formed of a material having a moisture permeability lower than that of paper. In general, in the case where paper is used as a housing member for housing an absorbent article, since the paper has a property of easily absorbing moisture, there is a risk that the absorber of the housed absorbent article absorbs moisture. In this regard, in the present embodiment, the layer formed of a material having a lower moisture permeability than that of paper (here, the innermost layer 10 b) is provided on the inner side in the thickness direction (the inner space side of the housing body 1) with respect to the outermost layer 10a formed of paper, and this suppresses entry of moisture into the interior of the housing member 10, which makes it possible to secure excellent moisture resistance.

Further, "a material having a lower moisture permeability than that of paper" can be represented by a moisture vapor permeability as an index of moisture permeability. It is possible, for example, to base on JIS Z0208: 1976 test method for determining the Water vapor Transmission Rate of moisture-proof packaging materials (disk method) the Water vapor Transmission Rate was measured. The measurements were made as follows: taking out the test piece from the paper forming the outermost layer 10a and the material forming the innermost layer 10 b; each test piece was attached to a moisture permeable cup containing a moisture absorbent (calcium chloride); each test piece was left to stand under prescribed temperature and humidity conditions for 24 hours; subsequently, the moisture vapor transmission amount (discharge amount) per unit area (m ²) was measured. The higher the value of the water vapor permeability, the higher the moisture permeability. A material having a water vapor permeability lower (smaller) than that of the paper constituting the outermost layer 10a is defined as "a material having a moisture permeability lower than that of the paper".

Further, it is preferable that such a material having a lower moisture permeability than paper is a resin sheet. Here, the "resin" constituting the resin sheet is a synthetic resin composed of a high molecular compound, and for example, thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, and polyethylene terephthalate (PET) can be used. Further, the innermost layer 10b is formed of a transparent resin so that the other side (rear side) can be at least seen through and visually recognized from one side (front side) in the thickness direction. In the present embodiment, it is desirable that the resin constituting the innermost layer 10b is colorless and transparent so as to make it easier to visually recognize the absorbent article 20 housed inside the housing member 10 from the outside of the housing body 1 through a window region 16 described later.

Further, as the resin sheet used as a material having lower moisture permeability than paper, for example, a laminated film of Polyethylene (PE) and polyethylene terephthalate (PET) stacked on each other can be used. In the laminated film disposed on the front surface 11 and the rear surface 12 of the housing member 10, the thickness of polyethylene terephthalate (PET) is preferably 12 μm, and the thickness of Polyethylene (PE) is preferably about 30 μm. In the laminated film disposed on the bottom surface 13, the thickness of polyethylene terephthalate (PET) is preferably 12 μm, and the thickness of Polyethylene (PE) is preferably about 60 μm. By using such a laminated film as the innermost layer 10b and laminating the innermost layer 10b and the outermost layer 10a formed of paper, a joint portion (indicated by a broken line in fig. 3A) where the innermost layer and the outermost layer 10a are joined to each other can also be formed. In this way, a surface (front surface 11, rear surface 12, or bottom surface 13) in which the front surface side (outside) is formed of paper and the rear surface side (inside) is formed of resin is formed. It should be noted that in the case of forming using the above-described laminated film and paper, the mass of each material in the housing member 10 is as follows: the mass of the paper is 9.3g; the mass of Polyethylene (PE) is 5.3g; the mass of polyethylene terephthalate (PET) was 2.1g. Further, the thickness of the paper is a standard of basis weight, and the basis weight of the paper used herein is 100g/m ².

When the housing member 10 is formed, the innermost layer 10B of the front surface 11 and the innermost layer 10B of the rear surface 12 are superposed on each other in the front-rear direction in a manner facing each other (see fig. 3A and 3B). In addition, in the lower end portion in the up-down direction of the housing member 10, the bottom surface 13 is arranged between the front surface 11 and the rear surface 12 in the front-rear direction in a state of being folded in half in the up-down direction so that portions of the outermost layer 10a face each other. Further, surfaces adjacent to each other in the front-rear direction (thickness direction) are joined to each other in a predetermined area.

Specifically, as shown in fig. 3A, at the lower end in the up-down direction, the innermost layer 10b in the front surface 11 and the innermost layer 10b in the bottom surface 13 constituting the housing member 10 are adjacent to each other in the front-rear direction and are joined to each other. The innermost layers 10b are joined to each other by, for example, a known welding means such as heat welding. Both the innermost layers 10b are resin sheet members and have thermoplasticity, so that the opposing sheet members can be joined to each other with sufficient strength using a welding means. In the same manner, at the lower end portion in the up-down direction, the innermost layer 10b of the rear surface 12 and the innermost layer 10b of the bottom surface 13 are joined (welded) to each other. Thus, a bottom seal 19 indicated by wavy lines in fig. 3A is formed. As shown by the hatching in fig. 2, at the lower end portion in the up-down direction of the housing member 10, the surfaces 11, 12, and 13 are continuously sealed by the bottom sealing portion 19 in the left-right direction.

Further, in the left-right direction end portions, as shown in fig. 3B, the innermost layer 10B of the front surface 11 and the innermost layer 10B of the rear surface 12 facing each other are joined. The innermost layers 10b are also joined to each other by using a welding means. In the same manner, at the lower end in the up-down direction, the innermost layer 10b of the front surface 11 and the innermost layer 10b of the bottom surface 13 are welded in the left-right direction end, and the innermost layer 10b of the rear surface 12 and the innermost layer 10b of the bottom surface 13 are welded in the left-right direction end. Thus, a pair of side seals 18 indicated by wavy lines in fig. 3B are formed. As shown by hatching in fig. 2, in both end portions in the left-right direction of the housing member 10, the surfaces 11, 12, and 13 are continuously sealed by the side seal portions 18 in the up-down direction.

As described above, in the bottom seal portion 19 and the pair of side seal portions 18, the following resin sheet members (low moisture permeability materials) are welded adjacent to each other in the front-rear direction: a resin sheet member provided in the innermost layer 10b of one surface (for example, the front surface 11) among the plurality of surfaces constituting the housing member 10; and a resin sheet member provided in the innermost layer 10b of a surface (for example, the bottom surface 13) different from the one surface. This makes it less likely that moisture will enter the inside of the housing body 1 (enter the housing space of the housing body), so that the moisture resistance can be further enhanced.

It should be noted that, in the bottom surface 13 folded in half in the up-down direction, the portions of the outermost layers 10a facing each other in the front-rear direction are also joined to each other in both end portions in the left-right direction and in the lower end portions in the up-down direction of the housing member 10. Since the outermost layer 10a is formed of paper, the portions of the outermost layer 10a are joined to each other by using an adhesive (indicated by a broken line in fig. 3B).

As described above, in the edge portion of the housing member 10, both end portions in the left-right direction and the lower end portion in the up-down direction are continuously locked by the pair of side seal portions 18 and the bottom seal portion 19. Meanwhile, in the edge portion of the housing member 10, the upper end portion in the up-down direction is not locked. Accordingly, the housing member 10 has an opening 10pn (see fig. 4 described later) on the upper side in the up-down direction, and has a bag shape with a bottom surface 13.

The opening 10pn of the housing member 10 has a sealing portion 14 that can be opened and closed. The sealing portion 14 is constituted by a pair of resin zippers or the like arranged in the left-right direction, and is provided on the innermost layer 10b of the front surface 11 and the innermost layer 10b of the rear surface 12, respectively, as shown in fig. 3A. The pair of sealing portions 14 and 14 facing each other in the front-rear direction are pressed and engaged with each other, thereby closing the opening portion 10pn and sealing the accommodation space of the accommodation member 10 (see fig. 1). Further, by pulling the joined seal portions 14 and 14 toward the opposite sides in the front-rear direction, the opening portion 10pn is formed again. As described above, the opening 10pn of the housing member 10 can be opened and closed freely by the sealing portion 14.

Fig. 4 is a diagram showing how the absorbent article 20 is put into the housing member 10 and taken out from the housing member 10. As shown in fig. 4, the opening 10pn is formed at the upper side in the up-down direction by pulling apart the sealing portion 14 of the housing member 10, so that the absorbent article 20 can be taken out and placed through the opening 10 pn. Further, after the operation of taking out the absorbent article 20 is performed, the opening portion 10pn can be closed by resealing the sealing portion 14, so that the moisture resistance in the accommodating space can be maintained.

Further, as shown in fig. 3A, in the housing member 10 of the present embodiment, the outermost layer 10a formed of paper and the innermost layer 10b formed of a material having a lower moisture permeability than paper are provided on the upper side and the lower side with respect to the sealing portion 14 in the up-down direction. The upper side portion of the sealing portion 14 is a portion gripped by a user when opening and closing the housing member 10, and in such upper side portion, the innermost layer 10b and the outermost layer 10a are provided, so that the gripped portion is less likely to be torn.

Further, as shown in fig. 1 to 3, the front surface 11 of the housing member 10 has a window area 16 and a non-window area 17, the window area 16 being formed at least partially only of the resin sheet serving as the innermost layer 10b, the non-window area 17 being an area where the paper serving as the outermost layer 10a and the resin sheet serving as the innermost layer 10b overlap. The user can visually recognize the inside of the housing member 10 from the front side of the housing body 1 through the window area 16. Furthermore, it is desirable that the surface area of the window region 16 is smaller than the surface area of the non-window region 17. Reducing the size of the window area 16 to the necessary minimum allows for reduced likelihood of moisture entering the interior of the housing member 10.

In the present embodiment, as shown in fig. 1 and 2, the window region 16 is continuously provided from one end side in the left-right direction to the other end side in the left-right direction along the left-right direction. The window area 16 is provided up to the end in the width direction (left-right direction), which makes it easier for the user to visually recognize the absorbent article 20 located inside without opening the housing body 1. This makes it possible to reduce the frequency of opening for confirmation or the like. Thus, this makes it possible to reduce the possibility of moisture entering the inside of the housing body 1.

(Absorbent article 20)

Fig. 5 is a plan view of the absorbent article 20 housed in the housing member 10 as seen from the front side in the front-rear direction. Fig. 6 is a plan view and a cross-sectional view of the absorbent article 20 in an unfolded and stretched state. In fig. 5 and 6, the absorbent article 20 has a longitudinal direction and a transverse direction intersecting each other. The longitudinal direction corresponds to the longitudinal direction of the absorbent article in a stretched state, and is a direction along the up-down direction in fig. 1. The lateral direction corresponds to the short-side direction of the absorbent article in a stretched state, and is a direction along the left-right direction in fig. 1.

In fig. 5 and 6, a tape type disposable diaper is shown as an example of the absorbent article 20 accommodated in the accommodating member 10. The absorbent article 20 includes an outer body 21, an inner body 22, an indicator 23, and a fastening tape 24.

The outer body 21 is an outer member that is provided at the closest non-skin side of the absorbent article 20 and supports the inner body 22. As the exterior body 21, a suitable nonwoven fabric, such as a spunbond/meltblown/spunbond (SMS) nonwoven fabric, may be used. Further, a predetermined pattern 25 may be provided on the non-skin-side surface of the outer body 21 (e.g., the outermost surface of the absorbent article 20). In the same manner as the graphic 15 provided on the receiving member 10, the graphic 25 is provided to allow the user to visually recognize the information of the absorbent article 20. In the present embodiment, as shown in fig. 5, as the graphic 25, information related to the name (product name) or the characteristics (material used) of the absorbent article 20, a picture (for example, a cotton graphic) for inducing imagination of the absorbent article 20, and the like are provided. In addition, the size of the target wearer or other information may be displayed.

The inner body 22 is a member corresponding to an absorbent main body that absorbs excrement. The inner body 22 includes: an absorber 22a; a skin side sheet 22b disposed on the skin side in the thickness direction with respect to the absorber 22a; and a non-skin side sheet 22c disposed on the non-skin side in the thickness direction with respect to the absorber 22 a.

The absorber 22a is a member that absorbs and retains excrement such as urine, and is formed by wrapping an absorbent core having a liquid absorbent material with a liquid-permeable core wrapping sheet. The liquid-absorbent material constituting the absorbent core may be made of, for example, liquid-absorbent fibers (e.g., pulp fibers) or liquid-absorbent particles (e.g., superabsorbent polymers, so-called SAP). Further, as the core wrap sheet, for example, a tissue paper may be used.

The skin side sheet 22b is a member that comes into contact with the skin of the wearer when the absorbent article 20 is worn, and is a liquid-permeable sheet member that permeates excrement from the skin side to the non-skin side in the thickness direction and moves the excrement to the absorber 22 a. As the skin side sheet 22b, a soft sheet member such as a breathable nonwoven fabric may be used. The non-skin side sheet 22c is a liquid-impermeable sheet member that inhibits liquid (e.g., urine) that has been absorbed by the absorber 22a from exuding to the non-skin side (the garment side of the wearer). As the non-skin side sheet 22c, for example, a soft sheet member such as a Polyethylene (PE) resin film may be used.

The indicator 23 is a detection portion for detecting at least one of urine and feces, and is provided between the absorber 22a and the non-skin side sheet 22c in the thickness direction. The indicator 23 of the present embodiment is configured as an indicator having a pH indicator employed in a conventional diaper. For example, the pH of the fecal matter is used as a reaction factor, and the excretion of urine or fecal matter is detected when the indicator exhibits a predetermined reaction (e.g., a color reaction) upon contact with the urine or fecal matter. Further, in fig. 5, one indicator 23 having a belt shape extending in the longitudinal direction is provided at the widthwise central portion. The arrangement and number of the indicators 23 may be appropriately changed depending on the type of excrement (urine or feces) to be detected, the amount of excrement, and the like.

The fastening tapes 24 are engaging members provided in pairs in the back-side longitudinal end portions of the outer case 21 in such a manner as to extend outward on both lateral sides. The fastening strips 24 each have hook and loop fasteners including hooks that engage fibers such as nonwoven. When the absorbent article 20 is worn, the pair of fastening tapes 24 and 24 are joined to the abdominal region of the outer body 21 (nonwoven fabric) by the joining force of the hook-and-loop fastener. Thereby, the waist opening and the leg openings of the absorbent article 20 are formed, so that the position of the absorbent article 20 with respect to the body (waist) of the wearer can be fixed.

When the absorbent article 20 is accommodated in the accommodation member 10, the pair of fastening strips 24 and 24 are folded inward in the lateral direction and folded in half at the longitudinal center portion such that the non-skin-side surface of the absorbent article 20 faces outward. As described above, the absorbent article 20 is folded into a compact shape as shown in fig. 5 such that the up-down direction of the receiving member 10 and the longitudinal direction of the absorbent article 20 are aligned with each other. The absorbent article 20 is put in and taken out through the opening 10pn (see fig. 4).

Further, the graphic 25 is provided on at least a part of the outermost surface (outer body 21) of the absorbent article 20, and it is desirable that the maximum density (density) of the graphic 15 provided on the outermost layer 10a of the receiving member 10 is higher than the maximum density of the graphic 25 provided on the outermost surface of the absorbent article 20. In this configuration, the graphic 25 provided on the outermost surface of the absorbent article 20 becomes inconspicuous with respect to the graphic 15 provided on the outermost layer 10a of the receiving member 10. That is, the graphic 25 of the absorbent article 20 becomes less likely to be visually recognized from the outside of the housing member 10. This makes it possible to further enhance the visibility of the graphic 15 provided on the housing member 10 side, and enables the user to easily recognize that the housing member 10 is formed of paper.

It should be noted that the concentration of the pattern can be measured as follows. First, the graphic 15 provided on the housing member 10 and the graphic 25 provided on the absorbent article 20 are imaged by a digital camera respectively a plurality of times under the same imaging conditions to obtain a plurality of image data. Next, these image data are put into a personal computer, and after the monochrome conversion, they are converted into gradations having 256 gradations, the highest gradation value of each of the patterns 15 and 25 is detected, and the highest gradation values of the plurality of image data are averaged to obtain the maximum density of each pattern.

(Other aspects of the storage body 1)

With respect to the housing body 1, the following aspects are possible in addition to the above aspects. Fig. 7A is a diagram showing a configuration of the graphic 15 provided on the housing member 10 according to other embodiments, and fig. 7B is a schematic sectional view showing a section taken along the line X-X of fig. 7A. Fig. 8 is a graph showing friction coefficients according to other embodiments. Fig. 9 is a graph showing measurement results of friction coefficients according to other embodiments. Fig. 10 is a diagram showing a surface roughness SMD according to other embodiments. Fig. 11 is a graph showing measurement results of the surface roughness SMD according to other embodiments. Fig. 12 is a view showing how the absorbent article 20 is taken out with a hand put in the gap of the housing member 10 according to other embodiments. Fig. 13 is a front view of the housing 1 according to another embodiment in a state of being inverted in the up-down direction.

(Aspect 1)

The storage body 1 of the absorbent article 20 includes: an absorbent article 20; and a housing member 10 housing the absorbent article 20, wherein the housing member 10 includes a paper layer 10a, at least a portion of the paper layer 10a is formed of paper, and at least a portion of the paper layer 10a has an unbleached pulp area formed of unbleached pulp.

By so doing, the absorbent article 20 is accommodated in the accommodation member 10 including an unbleached pulp area that is difficult to transmit light. This makes it possible to reduce the effect of ultraviolet light on the following constituent members that may turn yellow: elastic members such as rubber or polyurethane, which are typically included in absorbent articles; liquid impermeable films, and the like. Therefore, yellowing of the absorbent article 20 can be suppressed.

(Aspect 2)

The housing 1 of the absorbent article 20, wherein the graphic 15 is provided on at least a portion of the outer surface of the unbleached pulp area of the housing member 10.

In the case where the graphic 15 is provided on the outer surface of the paper layer 10a formed of bleached pulp, however, the graphic 15 may be less likely to be seen because the housed absorbent article 20 is seen through, because the unbleached pulp area has a large thickness and is brown or dark brown, the unbleached pulp area prevents the contents from being seen through and makes the graphic 15 easier to visually recognize.

(Aspect 3)

The absorbent article 20 comprises a case 1 having a vertical direction, a horizontal direction, and a front-rear direction intersecting each other, wherein a pattern 25 is provided on at least a part of the outermost surface of the absorbent article 20, wherein the pattern 15 provided in the unbleached pulp area is made to be a case member side pattern 15, the pattern 25 provided on the absorbent article 20 is made to be an absorbent article side pattern 25, and the case member side pattern 15 and the absorbent article side pattern 25 have overlapping portions when seen in the front-rear direction in a state in which the absorbent article 20 is positioned at a specific position in the case member 10.

By doing so, the unbleached pulp area has a large thickness and is brown or dark brown, etc., and therefore, even when the graphic 15 in the unbleached pulp area and the graphic 25 of the absorbent article 20 overlap, the graphic 15 on the absorbent article 20 is not seen through. This makes it possible to maintain the visibility of the graphic 15 provided in the unbleached pulp area.

(Aspect 4)

The storage body 1 of the absorbent article 20 includes: an absorbent article 20; and a housing member 10 that houses the absorbent article 20, wherein the housing member 10 includes an outermost layer 10a, at least a portion of the outermost layer 10a being formed of paper, wherein at least a portion of the graphic 15 is printed on an area of the outermost layer 10a having a brookfield smoothness (Beck smoothness) of less than 20 seconds.

In this case, printing the pattern 15 in such a manner as to overlap at least a part of the region where the brookfield smoothness of the outermost layer 10a is less than 20 seconds makes the pattern 15 formed in the region appear blurred. This can thus make it easier for the user to recall the texture or soft visual impression of the material of the receiving member 10 or the absorbent article 20 received therein.

(Aspect 5)

The container 1 of the absorbent article 20, wherein the container has an up-down direction, a left-right direction, and a front-back direction intersecting each other, wherein the graphic 15 (151) includes a first portion 151A and a second portion 151B different from the first portion 151A, wherein the first portion 151A and the second portion 151B have different positions in the front-back direction.

By so doing, the positions of the first portion 151A and the second portion 151B in the front-rear direction are different from each other, which allows the pattern 151 (15) to be recognized three-dimensionally. Therefore, the three-dimensionally enlarged shape of the housing member 10 is emphasized as compared with the case where the pattern 151 (15) is visually recognized in a plan view, and the user can more easily recall the soft visual impression of the housing body 1.

(Aspect 6)

The container 1 of the absorbent article 20 further includes: and side seal portions 18, the side seal portions 18 being portions, of both end portions in the left-right direction, of surfaces constituting the housing member 10, which are adjacent and welded in the front-rear direction, the surfaces being different from each other, wherein the first portions 151A are arranged at positions that do not overlap the side seal portions 18, and wherein the second portions 151B are arranged at positions that overlap the side seal portions 18.

By so doing, the pattern 151 is configured to span a planar region overlapping the side seal 18 and a curved region not overlapping the side seal 18 (overlapping the curved region 10cr, which is a region where the front surface 11 and the rear surface 12 are curved). Thus, the graphic 151 is visually recognized as having a more complex and three-dimensional shape, which can make it easier for the user to recall the soft visual impression of the housing body 1.

(Aspect 7)

The storage body 1 of the absorbent article 20 includes: an absorbent article 20; and a housing member 10 that houses the absorbent article 20, wherein the housing member 10 includes an outermost layer 10a and an innermost layer 10b, at least a portion of the outermost layer 10a is formed of paper, at least a portion of the innermost layer 10b is formed of resin, wherein the resin constituting the innermost layer 10b includes biomass plastic.

By so doing, the surface (outermost layer 10 a) of the housing member 10 is formed of paper, and this enables the user to easily recall that the housing body 1 is an environmentally friendly product. Meanwhile, by forming the rear surface (innermost layer 10 b) of the housing member 10 with resin, it is possible to increase moisture resistance and suppress the absorbent article 20 housed therein from becoming wet. Further, since the resin constituting the innermost layer 10b is composed of biomass plastic, the content ratio of petroleum derived materials can be reduced as compared with conventional products. Therefore, the housing 1 of the absorbent article 20 which is environment-friendly and has excellent moisture resistance can be provided.

(Aspect 8)

The weight of the biomass plastic included in the resin constituting the innermost layer 10b in the storage body 1 of the absorbent article 20 is 10% or more of the weight of the storage member 10.

By doing so, the standard of the content ratio of biomass plastics (biomass percentage of 10% or more) specified in "biomass marking system" formulated by japan organic resource society can be satisfied. This makes it possible to display an authentication mark (biomass mark 10%) of the system, enabling the user to easily recognize that the housing is an environmentally friendly product.

(Aspect 9)

The container 1 of the absorbent article 20 includes at least a part of members constituting the absorbent article 20 including biomass plastics (bio plastics).

By doing so, the biomass plastic is also included in the absorbent article 20, which makes it easier for the user to recognize that the absorbent article 20 is an environmentally friendly product, and that the user can use the absorbent article 20 with ease.

(Aspect 10)

The housing 1 of the absorbent article 20, wherein the ratio of the weight of the biomass plastic included in the housing member 10 to the weight of the housing member 10 is greater than the ratio of the weight of the biomass plastic included in the absorbent article 20 to the weight of the absorbent article 20.

By so doing, by increasing the content ratio of the biomass plastics in the housing member 10 to be higher than the content ratio of the biomass plastics in the absorbent article 20, the content ratio of the petroleum-derived raw material in the housing member 10 can be reduced by an amount corresponding thereto. This makes it possible to reduce the amount of petroleum-derived raw materials used and to realize a more environmentally friendly housing 1 for the absorbent article 20.

(Aspect 11)

The storage body 1 of the absorbent article 20 includes: a housing member 10 in which at least a part of the outermost layer 10a is formed of paper; and an absorbent article 20 which is accommodated in the accommodating member 10, and in which at least a part of the outermost surface is formed of a nonwoven fabric, wherein the minimum value of the coefficient of dynamic friction MIU of the innermost layer 10b of the accommodating member 10 is smaller than the coefficient of dynamic friction MIU of the outermost layer 10a of the accommodating member 10 formed of paper.

This makes it possible to suppress fuzzing of the nonwoven fabric at the time of taking out the absorbent article 20 while maintaining the appearance of the container body 1 as paper, as compared with the case where the coefficient of dynamic friction MIU of the innermost layer 10b is larger than that of the outermost layer 10 a.

(Aspect 12)

The housing 1 of the absorbent article 20, wherein at least a portion of the outermost surface of the absorbent article 20 is an opposing surface facing the housing member 10, and the minimum value of the coefficient of dynamic friction MIU of the innermost layer of the housing member 10 is smaller than the minimum value of the coefficient of dynamic friction MIU of the opposing surface.

This makes it possible to fuzze the nonwoven fabric when the absorbent article 20 is taken out, as compared with the case where the kinetic friction coefficient MIU of the innermost layer is larger than that of the facing surface of the absorbent article 20.

(Aspect 13)

The housing 1 of the absorbent article 20 has a coefficient of dynamic friction MIU of the outermost layer 10a formed of paper smaller than the maximum value of the coefficient of dynamic friction MIU of the outermost surface of the absorbent article 20.

In comparison with the case where the coefficient of dynamic friction MIU of the outermost layer 10a is larger than that of the opposite surface of the absorbent article 20, fuzzing of the nonwoven fabric due to contact of the receiving member 10 with the absorbent article 20 after removal of the absorbent article 20 can be suppressed.

(Aspect 14)

The housing 1 of the absorbent article 20, wherein at least a portion of the outermost surface of the absorbent article 20 is an opposing surface facing the housing member 10, wherein the minimum value of the coefficient of dynamic friction MIU of the surface of the absorbent article 20 at the closest skin side is smaller than the minimum value of the coefficient of dynamic friction MIU of the opposing surface.

When the absorbent article 20 is rubbed in a worn state, the wearer is less likely to feel uncomfortable than in the case where the coefficient of dynamic friction MIU at the skin-closest side of the absorbent article 20 is larger than the coefficient of dynamic friction MIU of the facing surface. Further, when the innermost layer 10b and the facing surface are rubbed, the portions of the surfaces located closest to the skin side are liable to slide with each other, and therefore, the facing surface is liable to move together with the innermost layer 10b, and fuzzing can be suppressed.

(Aspect 15)

The housing 1 of the absorbent article 20, wherein at least a portion of the outermost surface of the absorbent article 20 is an opposing surface facing the housing member 10, wherein the minimum value of the coefficient of dynamic friction MIU of the opposing surface is smaller than the minimum value of the coefficient of dynamic friction MIU of the surface of the absorbent article 20 located at the closest skin side.

This makes it easier to take out the absorbent article 20 from the housing member 10, as compared with the case where the coefficient of dynamic friction MIU of the facing surface of the absorbent article 20 is larger than that of the surface located closest to the skin side.

(Aspect 16)

The minimum value of the surface roughness SMD of the innermost layer of the housing member 10 is smaller than the surface roughness SMD of the outermost layer 10a of the housing member 10 formed of paper in the housing body 1 of the absorbent article 20.

By so doing, in the innermost layer 10b of the housing member 10, the surface roughness SMD is small, and this suppresses damage to the absorbent article 20 due to friction. In the outermost layer 10a, the surface roughness SMD is large, and this makes the outermost surface more easily grasped by fingers, so that the housing body 1 is more easily held.

(Aspect 17)

The housing 1 of the absorbent article 20, wherein at least a portion of the outermost surface of the absorbent article 20 is an opposing surface facing the housing member 10, wherein the minimum value of the surface roughness SMD of the innermost layer of the housing member 10 is smaller than the minimum value of the surface roughness SMD of the opposing surface.

By so doing, in the innermost layer of the housing member 10, the surface roughness SMD is small, and this suppresses damage to the absorbent article 20 due to friction. In the facing surface of the absorbent article 20, the surface roughness SMD is large, and this makes the facing surface more easily grasped by fingers, so that the absorbent article 20 is more easily taken out of the housing member 10.

(Aspect 18)

The housing 1 of the absorbent article 20 has a vertical direction, a horizontal direction, and a front-rear direction intersecting each other, the upper end portion of the housing member 10 is provided with an opening 10pn which is opened when the absorbent article 20 is taken out, and a gap is provided between the absorbent article 20 and the opening 10pn in a state where the housing 1 stands upright and the lower end of the housing 1 is in contact with the ground plane.

By so doing, a hand can be placed in the gap, and this makes it easier to spread the housing member 10 with fingers, making it less likely that the absorbent article 20 will be rubbed when taken out.

It should be noted that, as shown in fig. 1, in a state in which the housing body 1 stands upright and the lower end of the housing body 1 is in contact with the ground plane, the absorbent article 20 is in contact with the bottom surface 13 of the housing member 10 due to the own weight of the absorbent article 20, and is positioned at the center in the left-right direction. This state can be achieved, for example, by grasping and lifting the upper end portion of the housing member 10, slightly shaking the upper end portion up and down, and then slowly standing the housing body 1 upright. Further, in a state where the housing body 1 stands upright and the lower end of the housing body 1 is in contact with the ground plane, if at least a part of the indicator 23 overlaps the non-window area 17, the absorbent article 20 can move in the internal space. That is, the absorbent article 20 may be in contact with the bottom surface portion 13 of the housing member 10 and positioned at an arbitrary position in the inner space in the left-right direction.

(Aspect 19)

The housing 1 of the absorbent article 20 has an opening 10pn positioned below the upper end of the housing member 10.

By doing so, another gap (gap+portion from the opening portion 10pn to the upper end) is formed as compared with the case where the opening portion 10pn is provided at the upper end of the housing member 10, and this makes it easier to further spread the housing member 10 with fingers, so that the absorbent article 20 is less likely to be rubbed at the time of removal.

(Aspect 20)

The absorbent article 20 is accommodated in the accommodating body 1, wherein the accommodating body accommodates a plurality of absorbent articles 20, and the absorbent articles 20 are arranged side by side in the front-rear direction, not in the up-down direction and the left-right direction.

By so doing, there is no case where one row and the other row are in contact with each other, as compared with the case where the absorbent article 20 is arranged in two or more rows, which makes it possible to suppress collapse of alignment of the rows.

(Aspect 21)

The housing 1 of the absorbent article 20 is such that the upper and lower ends of the window area 16 overlap the absorbent article 20 when viewed in the front-rear direction in a state in which the housing 1 is upright and the lower end of the housing 1 is in contact with the ground plane.

This makes the boundary between the window region 16 and the non-window region 17 more prone to folding due to the change in rigidity. Thus, overlapping the upper and lower ends with the absorbent article 20 makes such portions less likely to be folded.

(Aspect 22)

In the case of the housing body 1 of the absorbent article 20, the upper end of the window area 16 is positioned above the center of the vertical direction of the absorbent article 20 in the housed state in a state where the housing body 1 stands upright and the lower end of the housing body 1 is in contact with the ground plane.

This makes the boundary between the window region 16 and the non-window region 17 more prone to folding due to the change in rigidity. For example, in the case where the used absorbent article 20 is folded in half in the up-down direction, by placing the used absorbent article 20 in the housing body 1, this easily makes the housing body 1 compact when discarded.

(Aspect 23)

The housing body 1 of the absorbent article 20, wherein the housing body 1 has an up-down direction, a left-right direction, and a front-back direction intersecting each other, the housing member 10 includes a front surface 11, a rear surface 12, and a bottom surface 13, gussets for forming the bottom surface 13 are provided between a lower end portion of the front surface 11 and a lower end portion of the rear surface 12, and no gussets are provided at an upper end portion of the housing member 10.

Since the lower end portion cannot be opened, the lower side of the housing member 10 is unfolded by providing the gusset in advance, which makes it possible to suppress friction of the housing member 10 and the absorbent article 20 when the absorbent article 20 is taken out.

(Aspect 24)

The absorbent article 20 is accommodated in the accommodation member 10 such that the crotch side of the absorbent article 20 is positioned on the upper side of the accommodation body 1, wherein the absorbent article 20 includes an abdomen portion 26 contacting the abdomen side of the wearer and a back portion 27 contacting the back side of the wearer, and the abdomen portion 26 and the back portion 27 face each other.

Since the crotch side of the absorbent article 20 has high rigidity, placing the absorbent article 20 in the container such that the crotch side is located on the upper side makes it easier to pull the absorbent article when taking out.

(Aspect 25)

The storage body 1 of the absorbent article 20, which has a vertical direction, a horizontal direction, and a front-rear direction intersecting each other, includes: a housing member 10; and an absorbent article 20 accommodated in the accommodation member 10 and including an indicator 23 for detecting excrement, wherein the accommodation member 10 includes: a window area 16, through which the absorbent article 20 can be visually recognized from the outside through the window area 16; and a non-window area 17 in which the absorbent article cannot be visually recognized, wherein at least a part of the indicator 23 overlaps the non-window area 17 when viewed in the front-rear direction in a state in which the housing body 1 is standing upright and the lower end of the housing body 1 is in contact with the ground plane.

This makes it possible to visually recognize the absorbent article 20 located inside from outside. In addition, the indicator 23 overlapping the non-window region 17 at the time of display or the like is suppressed from reacting with ultraviolet light, so that deterioration of the indicator 23 can be suppressed.

It should be noted that the expression "at least a portion of the indicator 23 overlaps the non-window region 17 when seen in the front-rear direction in a state in which the housing body 1 stands upright and the lower end of the housing body 1 is in contact with the ground plane" does not mean that "at least a portion of the indicator 23 overlaps the non-window region 17 when seen in the front-rear direction" is satisfied in the entire position if the absorbent article 20 moves in the left-right direction inside the housing member 10. But means that it is sufficient to achieve an overlap at any one position.

(Aspect 26)

In the case 1 of the absorbent article 20, the product pattern 25 is printed on the absorbent article 20, and at least a part of the product pattern 25 can be visually recognized from the outside of the case member 10 through the window area 16 in a state where the case 1 stands upright and the lower end of the case 1 is in contact with the ground plane.

This enables the consumer to check the product graphic 25 of the absorbent article 20 without having to open the absorbent article at the time of display or the like.

(Aspect 27)

The container 1 of the absorbent article 20, wherein the product graphic 25 includes a mark representing at least any one of the following: the country name of the absorbent article 20; a logo representing the name of the company that manufactured or sold the absorbent article 20; a logo representing the product name of the absorbent article 20; and the materials used in the absorbent article 20.

This enables a consumer to check at least one of the following without opening the absorbent article at the time of display or the like: the country in which the absorbent article 20 is manufactured; manufacturing a logo of a company name; a logo of the product name; and the materials used.

(Aspect 28)

The container 1 of the absorbent article 20, wherein the absorbent article 20 includes an abdomen 26 contacting the abdomen side of the wearer and a back 27 contacting the back side of the wearer, one of the abdomen 26 and the back 27 faces the window area in a state where the container 1 stands upright and the lower end of the container 1 contacts the ground plane.

This enables the consumer to check the front or back surface having a larger area than the side surface of the absorbent article 20 (diaper) without opening the absorbent article 20 at the time of display or the like.

(Aspect 29)

The absorbent article 20 is accommodated in the accommodating body 1, wherein the absorbent article 20 includes an abdomen 26 and a back 27, the abdomen 26 is in contact with the abdomen side of the wearer, the back 27 is in contact with the back side of the wearer, the abdomen 26 and the back 27 face each other, the absorbent article 20 is accommodated in such a manner that the crotch side of the absorbent article 20 is positioned at the lower side of the accommodating body 1, the absorbent article 20 has a crotch region which is positioned at the lowest position when the absorbent article 20 in the accommodated state is divided into four equal regions in the up-down direction, and at least a part of the crotch region overlaps with the non-window region 17 when viewed in the front-rear direction in a state in which the accommodating body 1 stands upright and the lower end of the accommodating body 1 is in contact with the ground plane.

Since the indicator 23 is particularly required in the crotch region, overlapping the crotch region and the non-window region 17 inhibits the reaction of the indicator 23 with ultraviolet light when displayed or the like. This makes it possible to suppress degradation of the indicator 23.

(Aspect 30)

The housing 1 of the absorbent article 20, wherein the indicator 23 of the absorbent article 20 includes a portion positioned at the abdomen 26 and a portion positioned at the back 27, one of the abdomen 26 and the back 27 facing the window area 16, and the portion of the indicator 23 positioned at the other of the abdomen 26 and the back 27 extends upward longer in the up-down direction than the portion positioned at the one of the abdomen 26 and the back 27.

The reaction of the indicator 23 with ultraviolet light when displaying or the like is suppressed (the portion of the indicator 23 overlapping the window region 16 is reduced) compared with the case where the portion of the indicator 23 having a longer length faces the window region 16. This makes it possible to suppress degradation of the indicator 23.

(Aspect 31)

The housing 1 of the absorbent article 20, wherein the indicator 23 of the absorbent article 20 includes a portion positioned at the abdomen 26 and a portion positioned at the back 27, one of the abdomen 26 and the back 27 facing the window area 16, and the portion of the indicator 23 positioned at one of the abdomen 26 and the back 27 extends upward longer in the up-down direction than the portion of the indicator 23 positioned at the other of the abdomen 26 and the back 27.

This makes it easier for the consumer to visually recognize the indicator 23 from the outside during display or the like, while suppressing deterioration of the crotch region in the non-window region 17, as compared with the case where the portion of the indicator 23 having a shorter length faces the window region 16.

(Aspect 32)

In the case of the housing 1 of the absorbent article 20, in a state in which the housing 1 stands upright and the lower end of the housing 1 is in contact with the ground plane, the upper and lower lengths of the overlapping portion of the non-window region 17 and the portion of the indicator 23 positioned at one of the abdomen 26 and the back 27 are longer than the upper and lower lengths of the overlapping portion of the window region 16 and the portion of the indicator 23 positioned at the one.

Therefore, a portion of the indicator 23 having a longer length can be visually recognized from the window region 16, and at the same time, making the length of the region overlapping with the non-window region 17 longer can suppress degradation of the indicator 23 as compared with the case of being shorter.

(Aspect 33)

In the case 1 of the absorbent article 20, the upper and lower length of the overlapping portion where the indicator 23 and the non-window area 17 overlap is longer than the upper and lower length of the overlapping portion where the indicator 23 and the window area 16 overlap in a state where the case 1 stands upright and the lower end of the case 1 is in contact with the ground plane.

Therefore, the reaction of the indicator 23 with ultraviolet light is suppressed at the time of display, as compared with the case where the length overlapping with the window area 16 is long, which makes it possible to suppress degradation of the indicator 23.

(Aspect 34)

The housing 1 of the absorbent article 20, wherein the upper end of the window area 16 does not overlap with the absorbent article 20 when viewed in the front-rear direction in a state in which the housing 1 is standing upright and the lower end of the housing 1 is in contact with the ground plane.

This enables the consumer to inspect the absorbent article 20 up to one end thereof without opening the absorbent article 20 at the time of display or the like.

(Aspect 35)

In the case of the housing 1 of the absorbent article 20, at least a part of the indicator 23 overlaps the non-window region 17 when viewed in the front-rear direction in a state where the vertical relationship is opposite to the state where the housing 1 stands upright and the lower end of the housing 1 is in contact with the ground plane.

Therefore, in a state in which the housing body 1 is reversed (since the housing member 10 is formed of paper, there is a gap inside, that is, in a state in which the absorbent article 20 moves upward inside the housing body 1), the reaction of the indicator 23 with ultraviolet light is suppressed, and this makes it possible to suppress degradation of the indicator 23.

(Aspect 36)

The housing body 1 of the absorbent article 20, wherein the housing member 10 includes a front surface 11, a rear surface 12, and a bottom surface 13, a gusset for forming the bottom surface 13 is provided between a lower end portion of the front surface 11 and a lower end portion of the rear surface 12, an upper end portion of the housing member 10 is not provided with a gusset, and in the lower end portion of the housing member 10, the bottom surface 13 is joined to at least one of the front surface 11 and the rear surface 12.

Therefore, since the number of the member layers joined in the lower end portion of the housing member 10 is larger than the number of the member layers joined in the upper end portion of the housing member 10. Therefore, the lower end portion of the housing member 10 is reinforced, so that it is possible to suppress the indicator 23 from being exposed due to damage of the lower end portion and suppress degradation of the indicator 23.

(Aspect 37)

The absorbent article 20 is accommodated in the accommodation member 10 such that the crotch side of the absorbent article 20 is positioned on the lower side of the accommodation body 1, wherein the absorbent article 20 includes an abdomen portion 26 contacting the abdomen side of the wearer and a back portion 27 contacting the back side of the wearer, and the abdomen portion 26 and the back portion 27 face each other.

Since the crotch side of the absorbent article 20 is thick, the portion of the receiving member 10 where the crotch side is located becomes liable to tear. However, the number of layers of the members joined in the lower end portion of the accommodating member 10 is larger than that in the upper end portion (the lower end portion is joined more firmly) than in the case where the crotch side is placed on the upper side of the accommodating member 10. This makes it possible to suppress the indicator 23 from being exposed due to damage of the housing member 10 and suppress degradation of the indicator 23.

(Aspect 38)

The storage body 1 of the absorbent article 20 includes: a housing member 10; and an absorbent article 20 accommodated in the accommodation member 10 and including an absorbent core 22a, wherein the graphic 15 is printed on the accommodation member 10, and at least a portion of the graphic 15 does not overlap the absorbent core 22a when the absorbent article 20 is seen in the thickness direction in a state in which the absorbent article 20 is positioned at a specific position in the accommodation member 10.

When a plurality of the containers 1 are arranged for packaging, this makes it possible to suppress friction of the graphics 15 between adjacent containers 1 or transfer of the color of the graphics 15 to the absorbent article 20.

It should be noted that, since the absorbent article 20 can move in the inner space of the housing member 10, the aforementioned positional relationship between the absorbent article 20 (absorbent core 22 a) and the graphic 15 may not be satisfied depending on the position in the inner space of the housing member 10. Therefore, the following states are explained: the absorbent article 20 is positioned at a specific position among any positions that can be taken in the interior space (any positions in the interior space) and satisfies the aforementioned positional relationship. It should be noted that the aforementioned positional relationship between the absorbent article 20 and the graphic 15 is always satisfied in some cases, and in this case, the absorbent article 20 in the internal space may take any position. It should be noted that the expression "at least a portion of the graphic 15 does not overlap the absorbent core 22a when the absorbent article 20 is seen in the thickness direction in a state in which the absorbent article 20 is positioned at a specific position in the housing member 10" does not mean that "at least a portion of the graphic 15 does not overlap the absorbent core 22a when the absorbent article 20 is seen in the thickness direction" is satisfied at the entire position if the absorbent article 20 moves inside the housing member 10. But means that it is sufficient to achieve no overlap at any one location. The same applies to the expression "in a state in which the absorbent article 20 is positioned at a specific position in the housing member 10".

(Aspect 39)

In the case of the container 1 of the absorbent article 20, at least a part of the graphics 15 does not overlap with the absorbent article 20 when the absorbent article 20 is viewed in the thickness direction in a state where the absorbent article 20 is positioned at a specific position in the container member 10.

(Aspect 40)

The container 1 of the absorbent article 20, wherein the area where the graphic 15 and the absorbent article 20 do not overlap when the absorbent article 20 is seen in the thickness direction is larger than the area where the graphic 15 and the absorbent article 20 overlap when the absorbent article 20 is seen in the thickness direction in a state where the absorbent article 20 is positioned at a specific position in the container member 10.

Therefore, friction of the graphic 15 or color transfer of the graphic 15 to the absorbent article 20 can be suppressed as compared with the case where the non-overlapping area is small.

(Aspect 41)

The container 1 of the absorbent article 20 is formed of paper at least a part of the outermost layer 10a of the container member 10, the interior of the container member 10 has an internal space, the internal space has a space where the absorbent article 20 is present and a gap space where the absorbent article 20 is not present, and when the absorbent article 20 is viewed in the thickness direction in a state where the absorbent article 20 is positioned at a specific position in the container member 10, at least a part of the graphics 15 overlaps with the gap space.

Therefore, since the absorbent article 20 is not present in the gap space, friction of the graphic 15 overlapped with such a portion or transfer of the color of the graphic 15 to the absorbent article 20 can be suppressed.

(Aspect 42)

The housing 1 of the absorbent article 20, wherein the housing 1 has an up-down direction, a left-right direction, and a front-back direction intersecting each other, the housing member 10 includes a front surface 11, a rear surface 12, and a bottom surface 13, a gusset for forming the bottom surface 13 is provided between a lower end portion of the front surface 11 and a lower end portion of the rear surface 12, an upper end portion of the housing member 10 is not provided with a gusset, and at least a part of the graphic 15 is positioned at an upper portion of the housing member 10.

Therefore, the distance between the front surface 11 and the rear surface 12 at the center in the left-right direction is shorter in the upper portion than in the lower portion. Thus, printing the graphic 15 on the upper portion makes it possible to widen the space between the graphics 15 of the adjacent containing body 1, which makes it possible to suppress friction of the graphics 15 of the containing member 10 or transfer of the color of the graphics 15 to the absorbent article 20.

(Aspect 43)

The container 1 of the absorbent article 20 has a top-bottom direction, a left-right direction, and a front-back direction intersecting each other, the upper end portion of the container member 10 is provided with an opening 10pn, the opening 10pn is opened when the absorbent article 20 is taken out, and the graphics 15 are not printed on the opening 10 pn.

Therefore, since the pattern 15 is not printed on the opening 10pn that the hand contacts when the absorbent article 20 is opened, transfer of ink to the hand and blurring of the pattern 15 can be suppressed.

The present disclosure may be changed or altered in various ways without departing from the gist of the present disclosure, and the present disclosure may include equivalents thereof.

In the above embodiment, the housing member 10 is formed of the front surface 11, the rear surface 12, and the bottom surface 13, but the configuration of the housing member 10 is not limited thereto. For example, a configuration in which the front surface 11, the rear surface 12, and the bottom surface 13 are formed of a single sheet member and the housing member 10 is formed by folding the single sheet member at a predetermined position is acceptable. That is, it is acceptable that the front surface 11, the bottom surface 13, and the rear surface 12 are a single member continuous in the lower end portion in the up-down direction in fig. 3 and that no bottom sealing portion 19 for sealing these surfaces is provided. Further, the housing member 10 may be configured without the bottom surface 13, and in this case, the lower end portion of the front surface 11 and the lower end portion of the rear surface 12 may be engaged with each other.
