It has a folded structure, and at both ends of the housing member in the left-right direction, the innermost layers have joint portions where portions facing each other in the front-rear direction are joined, and the outermost layers are joined to each other in the front-rear direction. A container for absorbent articles, characterized in that the portions facing each other in the front-rear direction have non-joined portions where they are not joined.

According to such a container for absorbent articles, in the locking portions provided at both ends in the left-right direction of the container containing the paper, the outermost layers have non-bonded portions, so that the conventional Compared to the case where the entire locking portion is welded in the film containing member, the bonding strength does not become too strong and the locking portion can be easily opened. Moreover, by making the surface of the package made of paper, it is possible to easily remind the user that the product is environmentally friendly.

In the case of such an absorbent article, it is desirable that the whole of the portions where the outermost layers face each other in the front-rear direction at both end portions in the left-right direction of the case member is a non-bonded portion. .

According to such a storage body for absorbent articles, when the storage member is unsealed, the two facing surfaces (outermost layers) arranged to face each other in the front-rear direction are not joined to each other. It becomes easier to separate the facing surfaces in the front-rear direction. Therefore, it is possible to make it easier for the user to peel off the engaging portion and open the container.

In the absorbent article storage body, the storage member includes side seal portions in which the resins constituting the innermost layer are welded to each other in a state adjacent to each other in the front-rear direction at both ends in the left-right direction. and a back seal portion in which the resins forming the innermost layer are welded together in a state adjacent to each other in the front-rear direction at the rear side portion in the front-rear direction.

According to such a container for absorbent articles, the sheet members made of thermoplastic resin are opposed to each other and joined by welding means, so that both sides in the left-right direction and the rear side in the front-rear direction are firmly secured. Sealed. That is, the entire innermost layer surrounding the accommodation space of the accommodation member is sealed. This makes it difficult for moisture to enter the inside of the container, and the moisture resistance can be further improved.

In the absorbent article container, the innermost layers of the containing member face each other in the front-rear direction in a region of a predetermined width from the outermost end in the left-right direction. It is desirable that it is not.

According to such a container for absorbent articles, a so-called dry edge is formed in which the sheet members (innermost layers) are not joined together at the laterally outer end portions. As a result, when the container is opened by peeling off the locking portions at both ends in the left-right direction, the dry edges serve as peeling starting points for peeling the locking portions (seal portions), making the opening operation easier. can do.

In such a container for absorbent articles, it is desirable that at least a portion of the outermost layer is provided with a design, and the design is made of water-based ink.

===Embodiment===

<Basic Configuration of Absorbent Article Container 1>
As a container for absorbent articles according to the present invention, an embodiment will be described by taking as an example a disposable diaper container 1 (hereinafter also simply referred to as "container 1") for containing disposable diapers. However, the absorbent article to be stored in the container 1 is not limited to disposable diapers, and may be sanitary napkins, panty liners, pads for light incontinence, etc., as long as they can be stored in the storage member.

FIG. 1A is a perspective view of a disposable diaper container 1 (container 1). FIG. 1B is a schematic cross-sectional view showing the AA cross section of FIG. The containing body 1 has a containing member 10 which is a bag-like member and a plurality of absorbent articles 20 (disposable diapers) contained inside the containing member 10 . Further, the container 1 (the container member 10) has an up-down direction, a left-right direction, and a front-rear direction that intersect each other.

The housing member 10 is formed by folding a sheet member 10s formed in a cylindrical shape along the left-right direction into a gusset at both ends in the up-down direction, and locking portions SW1 and SW2 at both ends in the left-right direction. It is a bag member having a substantially hexahedral shape. A specific structure of the housing member 10 will be described later. Inside the storage member 10, as shown in FIG. 1B, a storage space (a hatched area in FIG. 1B) having a substantially rectangular cross section is formed, and one or more absorbent articles 20 are placed in the storage space. It is possible to accommodate A plurality of absorbent articles 20 (four in FIG. 1B) are accommodated by stacking them in the front-rear direction, and an opening 10E (described later) is formed by opening one of locking portions SW1 and SW2 of the accommodating member 10. It can be taken in and out freely.

(Accommodating member 10)
2A and 2B are diagrams illustrating a sheet member 10s that constitutes the housing member 10. FIG. 3A to 3D are diagrams illustrating the structure and manufacturing method of the housing member 10. FIG. FIG. 4A is a schematic cross-sectional view showing the BB cross section of FIG. 3D. FIG. 4B is a schematic cross-sectional view showing the CC cross section of FIG. 3D.

The housing member 10 is formed of a laminated sheet member 10s (hereinafter simply referred to as a sheet member 10s) in which a plurality of sheet members are laminated in the thickness direction. In this embodiment, the sheet member 10s includes an outermost layer 10a arranged outside in the thickness direction (front side of the housing member 10) and an outermost layer 10a arranged inside in the thickness direction (back side of the housing member 10). It has a two-layer structure in which the inner layer 10b is joined. However, the sheet member 10s may have three or more layers.

At least a portion of the outermost layer 10a is made of paper. “Paper” here means paper made by agglutinating plant fibers and other materials, and in a broad sense, it includes synthetic paper made using synthetic high-molecular substances as the raw material, as well as paper containing fibrous inorganic materials. shall include Since the outermost layer 10a arranged on the outermost side of the container 1 is made of a paper material, it is easy for the user to recognize that the container 1 is a so-called "plastic-free" product in which petroleum-derived materials are reduced. , can provide users with an environmentally friendly image. Therefore, in the present embodiment, the outermost layer 10a is desirably made of "paper" made of vegetable fibers such as pulp fibers, and the entire outermost layer 10a is desirably made of paper.

Further, a predetermined pattern 15 may be provided on the surface of the outermost layer 10a (the front side in the front-rear direction of the container 1). The pattern 15 is provided to allow the user to visually recognize various information regarding the container 1 (absorbent article 20). In the present embodiment, as shown in FIG. 1A, the name (trade name) and features (materials used) of the absorbent article 20, a graphic (for example, a picture of cotton) that gives an image of the absorbent article 20, Information about the size of the target person is provided as a pattern 15 . In addition, as the pattern 15, display of various authentication marks (not shown) may be provided.

The pattern 15 is printed on the surface side of the outermost layer 10a by gravure printing or flexographic printing using a predetermined water-based ink. In general, water-based inks often use water as a solvent, and are safer and less odorous than oil-based inks using organic solvents and the like, and are environmentally friendly. On the other hand, water-based inks are weaker in adherence to print media than oil-based inks, and thus are sometimes difficult to use in commercial products. On the other hand, in the present embodiment, the outermost layer 10a, which is a non-printing medium, is made of paper, so that water-based ink easily adheres, and the pattern 15 can be stably formed. Therefore, from the viewpoint of environmental consideration, it is preferable to use water-based ink as the ink for printing the design 15 on the housing member 10 of the present embodiment.

At least a portion of the innermost layer 10b is made of resin. Here, the "resin" is a synthetic resin made of a polymer compound, and thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, and polyethylene terephthalate (PET) can be used. In addition, the innermost layer 10b is made of a transparent resin, and it is desirable that at least one side (front side) can be seen through the other side (back side) in the thickness direction. In particular, when the containing member 10 is provided with a window portion 16 (see FIG. 7 , details of which will be described later), the absorbent contained in the containing member 10 can be seen from the outside of the containing body 1 through the window portion 16 . It is desirable that the resin constituting the innermost layer 10b is colorless and transparent in order to make the functional article 20 easily visible.

The outermost layer 10a and the innermost layer 10b are laminated in the thickness direction as shown in FIG. 2B and bonded to each other with an adhesive or the like to form a sheet member 10s having a front surface made of paper and a back surface made of resin. be done.

When forming the housing member 10, first, as shown in FIG. 3A, the sheet member 10s is rolled into a cylinder so that the outermost layer 10a is on the front side and the innermost layer 10b is on the back side. Then, one end portion and the other end portion in the vertical direction are overlapped in the thickness direction (front-rear direction), and the overlapped portions are joined along the left-right direction to form the sheet member joint portion BW. The one end portion and the other end portion of the sheet member 10s are joined by using a known welding means such as heat welding. At that time, one end side of the sheet member 10s is bent along the bending line F1 along the left-right direction so that the innermost layers 10b, 10b face each other, and then the innermost layers 10b, 10b adjacent to each other in the front-rear direction (sheet member 10s) are welded together. Since the innermost layers 10b, 10b facing each other are both resin sheet members and have thermoplasticity, by using welding means such as heat welding, the facing sheet members can be joined with sufficient strength. can do. As a result, a back seal portion 17 is formed as indicated by the dashed line in FIG. 4B. Due to the back seal portion 17, the innermost layers 10b of the sheet member 10s on the rear side of the housing member 10 in the front-rear direction are continuously joined and sealed along the left-right direction.

Next, as shown in FIG. 3B, the tubular sheet member 10s is folded inward from both outer sides in the vertical direction to form gusset folded portions G1 and G2. Specifically, at the gusset folding portion G1, the sheet member 10s is folded from one side to the other side in the vertical direction along folding lines F2A and F2B along the horizontal direction. Then, the sheet member 10s is folded again along a folding line F3 along the left-right direction so that the outermost layers 10a face each other. As a result, a gusset folded portion G1 that is folded into a substantially M shape as shown in FIG. 3B is formed. As shown in FIG. 4A, in the gusset fold G1, a front facing surface 10agf, which is one surface of the outermost layer 10a, and a rear facing surface 10agb, which is the other surface, extend in the front-rear direction. They are facing each other. The gusset-folded portion G2 is also formed in the same manner as the gusset-folded portion G1.

Next, as shown in FIG. 3C, the sheet members 10s overlapped in the front-rear direction are joined together at one end in the left-right direction (the left side in FIG. 3C) to form a locking portion SW1. In the locking portion SW1, the innermost layers 10b, including the gusset folds G1 and G2, which are arranged to face each other in the thickness direction, are welded and joined together using known welding means such as heat welding. As described in the sheet member joint portion BW described above, the innermost layers 10b, 10b facing each other are sheet members made of resin and have thermoplasticity. By using it, the facing sheet members can be joined with sufficient strength. As a result, the side seal portions 18 are formed as indicated by broken lines in FIG. 4A. The innermost layers 10b, 10b of the sheet member 10s are continuously locked along the vertical direction at one end of the housing member 10 in the left-right direction by the side seal portion 18 . Although FIG. 4A is a diagram showing the cross-sectional structure of the locking portion SW2, since the locking portions SW1 and SW2 have the same structure, FIG. It also shows structure.

After one end in the horizontal direction (the left side in FIG. 3C) is locked by the locking portion SW1, the gusset folding portions G1 and G2 are widened to form a storage space having a substantially rectangular cross section. The absorbent article 20 is accommodated in the accommodation space from the other side (the right side in FIG. 3C). In the housing member having the gusset-folding structure as in the present embodiment, the gusset-folded portion of the sheet member 10s constituting the exterior spreads out as a so-called "gusset". Space can be formed. That is, since the capacity of the accommodation space is increased, it is possible to accommodate a large number of absorbent articles.

After the absorbent article 20 is accommodated, as shown in FIG. 3D, the sheet members 10s overlapped in the front-rear direction are joined together at the other end side in the left-right direction (on the right side in FIG. 3D) to form a locking portion SW2. do. The method of forming the engaging portion SW2 is the same as the method of forming the engaging portion SW1.

In this way, the containing member 10 is formed in a state in which a plurality of absorbent articles 20 are contained in the internal containing space.

(Absorbent article 20)
FIG. 5 is a plan view of the absorbent article 20 accommodated in the accommodating member 10 when viewed from the front side in the front-rear direction. FIG. 6 is a plan view and cross-sectional view of the absorbent article 20 in a state in which the absorbent article 20 is unfolded and stretched. 5 and 6, the absorbent article 20 has longitudinal and transverse directions that intersect each other. The longitudinal direction corresponds to the longitudinal direction of the absorbent article in the stretched state, and is the direction along the left-right direction in FIG. The lateral direction corresponds to the lateral direction of the absorbent article in the stretched state, and is the direction along the vertical direction in FIG.

FIGS. 5 and 6 show a tape-type disposable diaper as an example of the absorbent article 20 housed in the housing member 10. FIG. The absorbent article 20 has an outer body 21 , an inner body 22 , an indicator 23 and a fastening tape 24 .

The exterior body 21 is an exterior member that is provided on the non-skin side of the absorbent article 20 and supports the interior body 22 . Appropriate nonwoven fabric such as SMS (spunbond-meltblown-spunbond) nonwoven fabric can be used as the exterior body 21, for example. A predetermined pattern 25 may be provided on the non-skin side surface of the outer package 21 (that is, the outermost surface of the absorbent article 20). The pattern 25 is provided to allow the user to visually recognize information regarding the absorbent article 20, similar to the pattern 15 provided on the housing member 10. FIG. In the present embodiment, as shown in FIG. 5, the name (trade name) and characteristics (materials used) of the absorbent article 20, graphics (for example, a picture of cotton) that gives an image of the absorbent article 20, etc. Information is provided as graphics 25 . Also, the size of the wearer and other information may be displayed.

The inner body 22 is a member corresponding to an absorbent main body that absorbs excrement, and is composed of an absorbent body 22a, a skin-side sheet 22b arranged closer to the skin in the thickness direction than the absorbent body 22a, and a skin-side sheet 22b arranged closer to the skin than the absorbent body 22a. Also has a non-skin side sheet 22c arranged on the non-skin side in the thickness direction.

The absorbent body 22a is a member that absorbs and holds excrement such as urine, and is formed by covering an absorbent core containing a liquid absorbent material with a liquid permeable core wrap sheet. As the liquid absorbent material constituting the absorbent core, for example, liquid absorbent fibers such as pulp fibers, and liquid absorbent granules such as super absorbent polymer (so-called SAP) can be used. As the core wrap sheet, for example, tissue paper can be used.

The skin-side sheet 22b is a member that contacts the wearer's skin when the absorbent article 20 is worn, and allows excrement to permeate from the skin side to the non-skin side in the thickness direction and move to the absorbent body 22a. It is a liquid-permeable sheet member. As the skin-side sheet 22b, for example, a flexible sheet member such as an air-through nonwoven fabric can be used. The non-skin-side sheet 22c is a liquid-impermeable sheet member that prevents liquid such as urine absorbed by the absorber 22a from seeping out to the non-skin side (wearer's clothing side). As the non-skin side sheet 22c, for example, a flexible sheet member such as a polyethylene (PE) resin film can be used.

The indicator 23 is a detector for detecting at least one of urine and feces, and is provided between the absorbent body 22a and the non-skin side sheet 22c in the thickness direction. The indicator 23 of this embodiment is configured as an indicator containing a pH indicator that is used in conventional diapers. For example, with the pH of excrement as a reaction factor, urine or stool excretion is detected by exhibiting a predetermined reaction (for example, color reaction) upon contact with urine or stool. In FIG. 5, one strip-shaped indicator 23 is provided along the vertical direction at the center in the horizontal direction. and the amount of excretion can be changed as appropriate.

The fastening tape 24 is a pair of engaging members provided so as to extend outward in the horizontal direction at the back side end portion in the vertical direction of the exterior body 21 . The fastening tape 24 is provided with a hook-and-loop fastener having a hook that engages fibers such as non-woven fabric. Each is engaged in the ventral region of the body 21 (non-woven fabric). As a result, the waist opening and leg openings of the absorbent article 20 are formed, and the position of the absorbent article 20 can be fixed with respect to the wearer's body (torso).

When storing the absorbent article 20 in the storage member 10, the pair of fastening tapes 24, 24 are folded inward in the horizontal direction, and the non-skin side of the absorbent article 20 faces outward, and the central portion in the vertical direction is folded. to fold in half. In this way, the absorbent article 20 is folded into a compact shape as shown in FIG. 5 and accommodated so that the lateral direction of the accommodating member 10 is aligned with the vertical direction of the absorbent article 20 (see FIG. 3C).

<Regarding opening operation of container 1>
When the absorbent article 20 is taken out of the container 1 and used, one of the pair of locking portions SW1 and SW2 provided at both ends of the container 10 in the left-right direction is peeled off to form the opening 10E. Then, the absorbent article 20 is taken out from the opening 10E. For example, when the locking portion SW2 provided on the right side in the left-right direction is unsealed, the right end portion in the left-right direction becomes the opening 10E as shown in FIG. 3C.

In this embodiment, as shown in FIG. 4A, the innermost layers 10b, 10b of the locking portions SW1, SW2 are welded and joined by the side seal portions 18 at the portions facing each other in the front-rear direction. On the other hand, the portions where the outermost layers 10a, 10a face each other in the front-rear direction are not joined. This makes it easier to unseal the locking portions SW1 and SW2.

Conventionally, a storage member for an absorbent article having a gusset-fold structure is made of a liquid-impermeable sheet member such as a film or resin so as to prevent the absorbent article from getting wet due to permeation of moisture such as external moisture. It was common to be formed using When both ends of a housing member made of such a film sheet or the like are locked using a heat welding means, the entire heated region is melted and joined integrally, so the entire locking portion is joined. In some cases, the strength becomes very high, making it difficult to open the locking portion. In this case, it is necessary to provide an opening separately, or to process the film sheet so that it can be easily cut off.

On the other hand, since the housing member 10 of the present embodiment has a non-joint portion where the sheet members are not partially joined in the locking portions SW1 and SW2, the locking portions SW1 and SW2 can be unsealed. It is easier to perform the action to do. In FIG. 4A, the front facing surface 10agf and the rear facing surface 10agb of the outermost layer 10a forming the gusset fold G1 are not joined to each other at the locking portion SW2 (SW1). Similarly, the facing surfaces of the outermost layer 10a forming the gusset folds G2 are also not joined. This is because, in the housing member 10 of the present embodiment, the outermost layer 10a is made of paper, so even if the facing surfaces are heated, they are unlikely to be welded to each other.

Therefore, the joint strength of the locking portion SW2 (SW1) as a whole is weaker than that of the conventional film containing member as described above, and the user can easily peel off the locking portions SW1 and SW2 to open the package. Become. For example, in FIG. 4A, the front side portion of the gusset folded portion G1 (the portion provided with the front facing surface 10agf) and the rear side portion of the gusset folded portion G2 (the portion provided with the rear facing surface 10agb) are By grasping and pulling in the opposite direction in the front-rear direction, the locking portion SW2 can be easily opened. Further, since the sheet member 10s constituting the housing member 10 has at least a paper layer (the outermost layer 10a) and a resin layer (the innermost layer 10b), when the housing member 10 is composed only of the film sheet , the rigidity of the engaging portions SW1 and SW2 provided at the left and right ends is increased. Therefore, even if the user grabs and pulls the engagement portion when opening the container 1, the sheet member 10s is unlikely to be torn or stretched, and the opening operation can be performed smoothly.

Furthermore, in the container member 10 of the present embodiment, the package surface (the outermost layer 10a), which is often seen by the user and is easily noticeable, is made of paper. can make it easier to recall As a result, in the accommodating member 1 of the absorbent article having a gusset-folded structure having a wide accommodating space, it is possible to facilitate the opening of the engaging portion while considering the environment.

In addition, in this embodiment, the outermost layers 10a, 10a facing each other in the front-rear direction are entirely non-bonded at the locking portions SW1, SW2 provided at both ends of the housing member 10 in the left-right direction. For example, in the gusset-folded portion G1 of FIG. 4A, the entire regions of the front-side facing surface 10agf and the rear-side facing surface 10agb that face each other adjacently in the front-rear direction are non-bonded portions. Since the non-joint portion is provided widely in this manner, it becomes easier to separate the front side facing surface 10agf and the rear side facing surface 10agb back and forth when the container 1 is unsealed. , SW2 (side seal portion 18) can be easily peeled off and opened.

In the housing member 10 of the present embodiment, the innermost layer 10b at least partially made of resin is laminated on the back side in the thickness direction of the outermost layer 10a at least partially made of paper. The resin material constituting the innermost layer 10b has higher moisture resistance than the paper constituting the outermost layer 10a, and the innermost layer 10b made of resin having high moisture resistance is laminated on the back side of the outermost layer 10a made of paper. Accordingly, it is possible to prevent moisture such as humidity from entering the internal storage space from the outside of the storage member 10 . As a result, the quality of the absorbent article 20 housed in the housing member 10 can be easily maintained in good condition.

The housing member 10 has locking portions SW1 and SW2 (side seal portions 18) provided on both sides in the left and right direction, and a sheet member joint portion BW (back seal portion 17) provided on the rear side surface in the front-rear direction. , the resin innermost layers 10b, 10b are welded to each other while being adjacent to each other in the thickness direction. The sheet members (10b) made of thermoplastic resin are opposed to each other and joined together using a welding means, so that both sides in the left-right direction and the rear side in the front-rear direction are firmly sealed. That is, the entire innermost layer 10b surrounding the accommodation space of the accommodation member 10 is sealed. This makes it difficult for moisture to enter the interior (accommodation space) of the container 1, and the moisture resistance can be further improved.

Further, in the locking portions SW1 and SW2, there is a part of the region (the side seal portion 18) where the innermost layers 10b and 10b face each other, and there is a portion where the innermost layers 10b and 10b are not welded to each other. can be For example, a so-called dry edge, in which the innermost layers 10b and 10b are not joined to each other, occurs in a region of a predetermined width (for example, a region of 3 mm width) from the outermost end in the lateral direction of the locking portions SW1 and SW2. It may be formed. With such a configuration, when the container 1 is opened by peeling off the locking portions SW1 and SW2 (the side seal portions 18), the dry edges provided on the outer ends in the left-to-right direction are used to cut the side seal portions 18. Since it becomes a peeling starting point for peeling, it is possible to make the opening operation easier.

Further, the pattern 15 provided on the outermost layer 10a of the housing member 10 in this embodiment is printed using water-based ink. By using water-based ink, the amount of petroleum-derived organic solvent used can be reduced compared to the case of forming a pattern using oil-based ink. Further, since the outermost layer 10a of the housing member 10 is made of paper, the design 15 can be firmly fixed to the outermost layer 10a even when printing is performed without using an organic solvent. Therefore, a container 1 that is more environmentally friendly can be realized.

Further, a window portion 16 may be provided on the outer surface side (surface side) of the housing member 10 by cutting out a partial region of the outermost layer 10a. FIG. 7 is a plan view of the container 1 showing an example in which the window 16 is provided on the front side surface of the container 10. FIG. In FIG. 7, the outermost layer 10a of the sheet member 10s constituting the housing member 10 is partially cut out to form a window portion 16 in which the innermost layer 10b is exposed to the outer surface side. It is The user can see the inside of the housing member 10 (that is, the inside of the housing space) through the window 16 from the front side of the housing body 1 . Thereby, the user can visually recognize that the soft absorbent article 20 (paper diaper, etc.) is stored inside the storage member 10 . Therefore, the container 1 as a whole can easily remind the user of the material texture and soft image of paper.

At this time, the average density of the pattern 25 (corresponding to the pattern on the side of the absorbent article) provided on the outermost surface (exterior body 21) of the absorbent article 20 visible through the window portion 16 is higher than the average concentration of the pattern 25 on the side of the absorbent article 20. It is desirable that the average density of the pattern 15 (corresponding to the pattern on the housing member side) provided on the outer layer 10a is higher. The design 25 of the absorbent article 20 (design on the side of the absorbent article) visible through the window 16 looks thinner than the design 15 on the housing member (design on the side of the housing member), so that the absorbent article 20 itself is visible. is emphasized, and the soft image of the container 1 as a whole can be enhanced.

The pattern density can be measured as follows. First, the pattern 15 provided on the housing member 10 and the pattern 25 provided on the absorbent article 20 are photographed a plurality of times with a digital camera under the same photographing conditions to obtain a plurality of image data. Next, these image data are read into a personal computer, converted to gray scale of 256 gradations after monochrome conversion, and the highest gradation value is detected for each of pattern 15 and pattern 25, and the highest gradation value for a plurality of image data is detected. The tone values are averaged to obtain the maximum density of each pattern.

Further, in the present embodiment, as the material (paper) forming the outermost layer 10a of the housing member 10, paper made of unbleached pulp may be used. The paper made of unbleached pulp tends to give a natural feeling and makes the user feel the texture of the paper, so that the container 1 can be easily reminded that it is an environment-friendly product. Also, unbleached pulp has longer fibers than other materials and can form paper that is less likely to tear. Therefore, when the retaining portions SW1 and SW2 are peeled off to unseal the housing member 10, the outermost layer 10a is less likely to break, and the absorbent article 20 can be easily taken out.

In addition, in the housing member 10, the average value of the dynamic friction coefficients in the innermost layer 10b is preferably smaller than the average value of the dynamic friction coefficients in the outermost layer 10a. When the absorbent article 20 housed inside the housing member 10 is taken in and out from the opening 10E of the housing member 10 (see FIG. 3C), the outermost surface of the absorbent article 20 is aligned with the innermost surface of the housing member 10 (see FIG. 3C). It is put in and taken out while rubbing against the innermost layer 10b). Therefore, if the dynamic friction coefficient of the innermost layer 10b in the housing member 10 is equal to or higher than the dynamic friction coefficient of the outermost layer 10a, the absorbent article 20 is likely to be caught on the innermost surface (innermost layer 10b) of the housing member 10, There is a possibility that the removal operation may be easily obstructed. On the other hand, by making the average value of the dynamic friction coefficients of the innermost layer 10b of the container member 10 smaller than the average value of the dynamic friction coefficients of the outermost layer 10a, the appearance of the container 1 can be maintained as paper, while the innermost layer Compared to the case where the coefficient of dynamic friction of the outermost layer 10b is larger than the coefficient of dynamic friction of the outermost layer 10a, the operation of taking out the absorbent article 20 can be performed smoothly.

The dynamic friction coefficient can be measured, for example, as follows. First, the outermost layer 10a and the innermost layer 10b, which are the portions to be measured, are cut into a predetermined size (for example, about 10 cm long and 20 cm wide), and a plurality of pieces (for example, 10 pieces) are prepared as samples. Next, for each sample, the frictional force is measured using the frictional force detection function of an automated surface tester (KESFB4-AUTO-A manufactured by Kato Tech Co., Ltd.). The measurement conditions are that the contact area of the friction element is 5 mm×5 mm (0.25 cm ² ) and the load W is 50 gf (about 0.5 N) in the vertical direction including the weight of the friction element. Then, a tension of 400 g is applied to a sample width of 20 cm, the sample is set in an automated surface tester, the friction element is brought into contact with the sample with a load W, and the moving speed of the friction element is 1 mm / sec. F is measured, and the average value of the dynamic friction coefficient is calculated.
