The absorbent article described in the present embodiment is a sanitary article that absorbs and retains liquid moisture such as urine and menstrual blood (hereinafter referred to as “excreted moisture”) excreted from the wearer when worn. The absorbent article includes a tape-type paper diaper (a so-called “disposable diaper”).
In the following embodiments, a tape-type paper diaper (hereinafter, simply referred to as “tape-type diaper”) will be exemplified as an absorbent article.

A tape-type diaper is a type of diaper that is worn by a wearer and absorbs and retains excrement moisture. The tape-type diaper has a front body and a back body separated before and after the waist, unlike a pants-type diaper in which the waist of the wearer is continuously formed in a circumferential shape. This tape-type diaper is worn by various wearers, such as infants and adults, who need care.

In the present embodiment, directions used for description are defined as follows.
Regarding the tape-type diaper, a longitudinal direction is defined as a direction connecting a front body arranged to face the abdomen of the wearer and a rear body arranged to face the back. Between these front body (one side in the longitudinal direction) and the back body (the other side in the longitudinal direction) (the center in the longitudinal direction), a crotch arranged at the wearer's crotch (disposed opposite the crotch) Department is located. Further, in a state in which the tape-type diaper is worn on the wearer (hereinafter abbreviated as “wearing state”), a side facing the wearer's skin (inside in the wearing state) is a skin surface side (skin-facing surface side), The opposite side (outside in the mounted state) of the skin side is defined as the non-skin side (skin non-opposite side). Further, a direction connecting the skin surface side and the non-skin surface side is defined as a thickness direction, and a direction orthogonal to both the longitudinal direction and the thickness direction is defined as a width direction. In addition, viewing from a direction along the thickness direction is referred to as a plan view. The width direction in plan view is also called left and right.
In the present specification, for example, the notation of a numerical value range of “1 to 100” includes both the lower limit value “1” and the upper limit value “100”. The same applies to the notation of other numerical ranges.

[I. First Embodiment]
[1. Constitution]
First, the basic configuration of the tape-type diaper 1 will be described with reference to FIGS. After that, the detailed configuration of the tape-type diaper 1 will be described. In the following description, “tape-type diaper” is simply referred to as “diaper”.

[1-1. Basic configuration]
The diaper 1 is configured symmetrically with respect to the center line CL1 in the width direction. The diaper 1 is roughly divided into three regions along the longitudinal direction L: a front body 1A, a crotch 1B, and a back body 1C.

<Absorber>
The diaper 1 has a built-in absorber 10 extending in the longitudinal direction over the front body 1A, the crotch 1B, and the back body 1C. The absorbent body 10 is arranged in the entire crotch portion 1B in the longitudinal direction, and is arranged in most of the front body 1A and the back body 1C except for the longitudinal ends.
The absorber 10 is a mat-shaped member that absorbs and retains moisture. In this absorbent body 10, a mat in which a water-absorbing resin (also referred to as "SAP (Super Absorbent Polymer)") is mixed with pulverized or defibrated pulp (so-called "fluff pulp") is made of a hydrophilic nonwoven fabric or tissue. Wrapped in a wrap sheet.

<Seat>
On the skin side and the non-skin side with respect to the above-described absorber 10, various sheets 11, 12, 13, and 14 described below are provided over the entire area in the longitudinal direction of the diaper 1, and the main body 100 is configured. . That is, the main body 100 is a laminate of the absorber 10 and the sheets 11, 12, 13, and 14.
For the absorber 10, a center sheet 11 is laminated on the skin side, and a back sheet 12 is laminated on the non-skin side. The cover sheet 14 is laminated on the non-skin side of the back sheet 12. A side sheet 13 is arranged on the side (outside in the width direction) of the center sheet 11.

The center sheet 11 has water permeability in order to allow moisture to permeate and be absorbed by the absorber 10. The center sheet 11 is disposed closest to the skin surface of the diaper 1 except for the side sheet 13 (see FIG. 1). For this reason, the center sheet 11 is also referred to as a “top sheet”. The center sheet 11 has a larger dimension in the width direction than the absorber 10 and covers the absorber 10 from the skin surface side.

The back sheet 12 has water impermeability to prevent liquid leakage from the absorber 10.
The side sheet 13 has hydrophobicity in order to prevent the liquid from leaking laterally. The side sheet 13 is disposed closest to the skin surface of the diaper 1. For this reason, the side seat 13 is also referred to as a “top sheet”, like the center seat 11.

The cover sheet 14 covers the absorbent body 10 and the sheets 11, 12, and 13 from the non-skin side. The cover sheet 14 is provided to reinforce the back sheet 12 and to improve the tactile sensation (for example, touch). As the cover sheet 14, it is preferable to use a so-called air-through nonwoven fabric from the viewpoint of enhancing the air permeability.
The cover sheet 14 is not limited to a single-layer structure, and may have a multi-layer structure having an inner cover sheet and an outer cover sheet.

<gather>
In addition, the diaper 1 is provided with gathers, such as a three-dimensional gather 21, a leg gather 22, and a waist gather 23, in order to enhance the ability to follow the wearer in the worn state. In these gathers 21, 22, 23, the side sheet 13 and the back sheet 12 to which the thread rubbers 31, 32, 33 (elastic members) are attached are wrinkled. Note that an elastic member such as natural rubber or an elastic film may be used instead of or in addition to the thread rubbers 31, 32, and 33.

The three-dimensional gathers 21 are disposed inside the side sheet 13 in the width direction to prevent excrement from leaking to the outside in the width direction. In the three-dimensional gather 21, a rubber thread 31 is provided along the longitudinal direction at the inner edge in the width direction of the side sheet 13.
The leg gathers 22 are provided at locations where the diapers 1 are to be attached to the wearer's legs and become peripheral edges of the wearer's legs in the mounted state. In this leg gather 22, a thread rubber 32 is provided along the longitudinal direction at the outer edge in the width direction of the back sheet 12 in the crotch portion 1B and its periphery.
The waist gather 23 expands and contracts in the width direction and is provided at a longitudinal end of the back body 1C in order to adjust the fit of the wearer's waist. In this waist gather 23, a thread rubber 33 is provided along the width direction.

<Fastening mechanism>
The diaper 1 is provided with a pair of fastening portions 6, 6 so-called fastening tapes 6, 6 attached to the rear body 1C so as to extend outward in the width direction, and the most non-skin side of the front body 1A. The patch 4 is provided on the (outer surface). Here, a rectangular patch 4 is used. The diaper 1 is attached to the wearer by the fastening tapes 6 and 6 being pulled and fixed to the patch 4 and fixed. In the following, “fastening tape” is abbreviated as “tape”.
The patch 4 and the tape 6 constitute a fastening mechanism for realizing the fastening function. 1 and 2 illustrate a pair of tapes 6 and 6 provided one by one on both sides in the width direction of the back body 1C of the main body 100. However, the number of tapes 6 provided at the end in the width direction W is not particularly limited, and it is sufficient that at least one tape 6 is provided at least on both sides in the width direction.

(Fastening tape)
The tape 6 has a base sheet 61 (hook carrier) and a locking member 62 (mechanical fastener).
The base 61A (indicated only at one location) on the inner side in the width direction of the base sheet 61 may be thermally fused to the side sheet 13 and / or the cover sheet 14 by, for example, heat sealing or ultrasonic sealing, It may be bonded to the side sheet 13 and / or the cover sheet 14 with an adhesive such as hot melt. Further, as shown in FIG. 1, the base 61 </ b> A may be sandwiched between the side sheet 13 and the cover sheet 14 and may be heat-sealed or bonded to the sheets 13 and 14. That is, in the mode in which the base 61A is sandwiched between the side sheet 13 and the cover sheet 14, the widthwise outer end of the side sheet 13 is laminated on the skin surface side with respect to the base 61A. Of these, the outer end in the width direction is laminated on the non-skin side.
Further, in the base sheet 61, an extension 61 </ b> B except for the base 61 </ b> A (only one reference numeral is attached) is provided so as to extend outward in the width direction from the sheets 13 and 14.

材料 As a material constituting the base sheet 61, for example, a woven cloth, a nonwoven cloth, other cloth, paper, a plastic film, or a composite material thereof can be used. Further, as a material constituting the nonwoven fabric, it is preferable to use, for example, a polyethylene-based, polypropylene-based, polyamide-based, polyester-based, polyvinyl chloride-based or polystyrene-based synthetic resin.

The locking member 62 is provided on the skin side of the extending portion 61B of the base sheet 61. That is, the locking member 62 and the main body 100 are connected in the width direction by the base sheet 61. The locking member 62 is a member that can be engaged with the patch 4. The locking member 62 may be, for example, an adhesive or an adhesive tape, or may be a planar fastener mechanically coupled to the patch 4. The planar fastener is a mechanism for fixing the hook member (male member) and the loop member (female member) by mechanical connection. The planar fastener is composed of, for example, a combination of a hook material having a large number of protrusions (hook-like, mushroom-like, etc.) formed on the surface and a loop material having loop-shaped fibers arranged on the surface. For example, a hook material may be used as the locking member 62 of the tape 6 and a loop material may be formed on the surface of the patch 4. However, it is also possible to adopt a loop material as the locking member 62 of the tape 6 and form a hook material on the surface of the patch 4. When the hook member is attached to the surface of the loop member, a number of protrusions of the hook member engage with the surface of the loop member. Therefore, according to the planar fastener, the hook member and the loop member can be firmly fixed in a peelable state. As described above, it is preferable to use the planar fastener in that it can be used repeatedly and has high fixing strength.

(patch)
The patch 4 is provided on the outer surface of the front body 1 </ b> A of the main body 100 in order to facilitate the fastening of the tape 6. That is, the patch 4 is packaged (laminated) on the non-skin side of the main body 100.
When the locking member 62 is a hook material, a film-type patch having a film layer and a loop material provided on the entire outer surface thereof can be suitably used as the patch 4. The hook member of the locking member 62 can be detachably engaged with the loop member. As the loop material in this case, in addition to the form in which a net-like body knitted with a thread and having a loop is attached on the film layer, a non-woven fabric of a thermoplastic resin is intermittently ultrasonically sealed with the film layer And a form in which the fibers of the nonwoven fabric form a loop. Further, as the patch 4, a filmless type in which a nonwoven fabric of a thermoplastic resin is embossed and has no film layer can be used. As a material forming the film layer or the loop material, a nonwoven fabric is preferable, and a nonwoven fabric using a synthetic resin or the like exemplified as the material forming the base sheet 61 is more preferable.

The patch 4 satisfies at least one of the functions 1 to 3 exemplified below.
-Function 1: Function to indicate an appropriate position for attaching the locking member 62-Function 2: Function to stabilize repeated fastening of the locking member 62-Function 3: Locking member that cannot be fixed to the cover sheet 14 Function 1 for Securing the Stopping Point of 62 The function 1 described above contributes to fastening of the tape 6 to an appropriate position by fastening the locking member 62 to the extension range of the patch 4 and to the wearer. Contributes to the proper wearing of the diaper 1.
The above function 2 provides the patch 4 with strength (physical properties) that makes it difficult for the hook member 62 to be fluffed when the hook member 62 is repeatedly fastened, so that the fastening member 62 can be stably fastened repeatedly. If the hook members are repeatedly fastened to the cover sheet 14 (nonwoven fabric), the nonwoven fabric may be fluffed or the fastening stability may be reduced. On the other hand, fixing the locking member 62 to the patch 4 contributes to suppressing fluffing and securing the fixing stability.
The above-mentioned function 3 can secure a place to which the locking member 62 is fixed when the locking member 62 is not fixed to the cover sheet 14.

<Sheet lamination section>
The sheet stacking section 50 is a connection portion between the main body 100 and the tape 6. In the sheet stacking section 50, the base 61A (the sandwiching portion, only one of which is denoted by a reference numeral) of the base sheet 61 in the width direction includes a side sheet 13 (skin side sheet) and a cover sheet 14 (non-skin side). Sheet). The extension portion 61B (only one reference numeral is given) excluding the base portion 61A is provided so as to extend outward in the width direction from the sheets 13 and 14.

As shown in FIG. 4, in the sheet stacking unit 50, the outer edge in the width direction (hereinafter, referred to as “side outer edge”) 13 a of the side sheet 13 with respect to the base 61 A of the base sheet 61 is a skin surface. The outer edge of the cover sheet 14 in the width direction (hereinafter, referred to as “cover outer edge”) 14a is stacked on the non-skin side. That is, in the sheet stacking unit 50, two types of sheets 13 and 14 are stacked on the skin side and the non-skin side with respect to the width direction inner side of the base sheet 61. In FIG. 4, the dimensions in the thickness direction are exaggerated for easy understanding of each configuration.

Further, the side sheet 13 and the cover sheet 14, the outer edge portions 13a, each of 14a is bonded (coupled) with the base 61A of the base sheet 61 by the adhesive layer L _12. Specifically, the side edge portion 13a and the base portion 3A is adhered by the first adhesive layer L _1, and the cover outer edge 14a and the base portion 3A are bonded with a second adhesive layer L _2. The adhesive layer L _12, it is preferable to use an adjustable on-demand adhesive exhibits timing of adhesive performance.
Examples of the on-demand adhesive include a hot melt adhesive and a UV (UltraViolet) curing adhesive. The hot melt adhesive is cured after being melted by applying heat. The UV-curable adhesive is cured by being irradiated with ultraviolet rays. In other words, hot melt adhesives do not exhibit adhesive performance until heat is applied. Similarly, UV-curable adhesives do not exhibit adhesive performance until they are irradiated with ultraviolet light.

The adhesive layer L _12, a special equipment not be necessary as UV radiation, it is particularly preferable to use a hot melt adhesive. However, other known adhesives may be used in the adhesive layer L _12. Alternatively, instead of the adhesive layer L _12, it may be replaced with adhesive function of the adhesive layer L ₁₂ by adhesive means such as ultrasonic welding or heat sealing.

<Design Department>
As shown in FIG. 2, the main body 100 is provided with a pair of design portions 5A and 5B that can be viewed from the front 1A and the back 1C. The design units 5A and 5B have characters, figures, symbols, patterns or colors or a combination thereof (hereinafter simply referred to as "patterns"), and can visually distinguish the design units 5A and 5B from the other parts. Area. Such design portions 5A and 5B are provided by performing printing on the non-skin side of the back sheet 12 or the cover sheet 14, for example. Alternatively, the design part 5 is separately provided between the back sheet 12 and the cover sheet 14. FIG. 2 shows the design sections 5A and 5B provided on the back sheet 12.
In the front body 1A and the back body 1C, the area where the design parts 5A and 5B are arranged is not particularly limited. For example, in FIG. 2, in each of the front body 1 </ b> A and the back body 1 </ b> C, a longitudinal boundary is defined in a range from a longitudinal end of the main body 100 to a position of about ３ or の of a longitudinal dimension. The design portions 5A and 5B are defined, and the boundaries in the width direction are defined in a range substantially equal to the width dimension of the absorber 10.
The design portions 5A and 5B may have the same design or different designs. The design parts 5A and 5B may have the same design at least in part. In the following, “ design units 5A and 5B” may be simply referred to as “design unit 5”.

As shown in FIG. 2, the design sections 5A and 5B exemplified here include a front design section 5A (first design section) of the front body 1A and a rear design section 5B (second design section) of the back body 1C. Is provided.
The appearance of the design units 5A and 5B of the present embodiment is the same or similar to each other. The “ design portions 5A and 5B having the same or similar appearance” here include at least one of modes 1 to 4 listed below.
-Aspect 1: Design parts 5A and 5B having the same or similar color or pattern
-Aspect 2: Design parts 5A and 5B with the same or similar pattern arrangement
-Aspect 3: Design portions 5A and 5B having the same or substantially the same width dimension.
Aspect 4: Design portions 5A and 5B having the same or substantially the same longitudinal dimension
For example, the design portions 5A and 5B have a line-symmetric or substantially line-symmetric appearance in the longitudinal direction.

[1-2. Detailed configuration]
In the main body 100 provided with a pair of design portions 5A and 5B that can be seen on the front body 1A and the back body 1C, the patch 4 is exteriorly provided on the front design part 5A (disposed on the non-skin side). As shown in FIG. 2, the patch 4 has an overlapping part 4A (main part) with the front design part 5A, and the tape 6 is fixed to the overlapping part 4A. When the width dimension of the patch 4 is larger than the width dimension of the front design part 5A, the patch 4 includes non-overlapping parts 4B and 4B that do not overlap with the design part 5 on the outside in the width direction of the overlapping part 4A. May have.
In the diaper 1 having such a configuration, visual confusion between the front design portion 5A and the patch 4 may be caused, and it becomes difficult to visually recognize on which side of the design portions 5A and 5B the patch 4 is arranged. That is, it may be difficult for the user to determine the position of the patch 4. If the position of the patch 4 cannot be determined, it is difficult for the user to quickly fix the tape 6 at an appropriate position and wear the diaper 1 on the wearer with an appropriate fit. In addition, since the user may recognize the position of the patch 4 before and after the diaper 1, if the position of the patch 4 cannot be determined, there is a possibility that the user may mistake the position of the diaper 1 before and after the wearer.
In particular, in order to improve the visibility and appearance of the design portion 5, the patch 4 having light transmittance, that is, a patch 4 using a transparent or translucent material, or a color similar to the color of the previous design portion 5A is provided. Provision of an overlapping portion 4A integrally forming the appearance of the front design portion 5A, such as the patch 4, the patch 4 having the same design as the front design portion 5A, and the patch 4 having at least a part of the same design as the front design portion 5A. In the case where the patch 4 thus obtained is packaged in the design unit 5, the position of the patch 4 tends to be more difficult to determine. When the main body 100 is provided with the design portions 5A and 5B having the same design, or the design portions 5A and 5B having the same design at least in part, it is particularly difficult to distinguish the front and rear of the diaper 1. Tend.
The “light transmittance” of the patch 4 is a function of transmitting light to the design portion 5 at the position where the patch 4 is provided and transmitting the reflected light reflected by the design portion 5 to a visible extent. is there. Further, “similar colors” means colors of the same system including substantially the same colors, that is, colors having the same or similar hue.

(4) The diaper 1 is stored in a package in a state of being folded into a predetermined shape at the time of shipment. For example, in the diaper 1, the tape 6 is folded at the width direction end of the main body 100 with the skin side inside. Further, both ends in the width direction W of the absorber 10 (here, both ends in the width direction W of the design portions 5A and 5B, and the design portions 5A and 5B are arranged inside the virtual lines VL1 and VL2 in the width direction). At a pair of imaginary lines VL1 and VL2 (bent curves) that are orthogonal to the width direction W and extend in the longitudinal direction L, a portion outside the imaginary lines VL1 and VL2 in the width direction is folded back with the skin side inside. (See FIGS. 3A and 3B). Thereafter, the diaper 1 is folded in three in the longitudinal direction L by virtual lines VL3 and VL4 (folding lines) extending in the width direction W, and becomes a folded state of a predetermined shape (see FIG. 3C). .

Such a folding process is generally incorporated into a part of the diaper 1 manufacturing line. If the diaper 1 in the unfolded state is not folded at an appropriate position (for example, the virtual lines VL1 and VL2), the diaper 1 in the folded state does not have a predetermined shape, and its size varies. As a result, when the folded diaper 1 is stored in the package, the package may be damaged. That is, it becomes difficult to store the folded diaper 1 in the package, which may cause a decrease in the productivity of the diaper 1.
In particular, since the folding process along the virtual lines VL1 and VL2 is performed while checking the skin surface side of the diaper 1 in the unfolded state, the main body 100 has substantially the same color when viewed from the skin surface in a plan view. In such a case, it is difficult to determine an appropriate position to be folded.

When using the folded diaper 1 (see FIG. 3C), the user first unfolds the diaper 1 along the virtual lines VL3 and VL4 in the longitudinal direction L (see FIG. 3B). Next, the user develops a return by the virtual lines VL1 and VL2. Then, the tape 6 folded back to the skin side is deployed, and the diaper 1 is attached to the wearer.

Hereinafter, as shown in FIGS. 3A to 3C, a state where at least the virtual lines VL1 and VL2 are folded is referred to as a “folded state”. In the folded diaper 1, the first surface in the width direction outside the pair of virtual lines VL1 and VL2 faces and overlaps the second surface in the width direction inside the pair of virtual lines VL1 and VL2. Can be In addition, as shown in FIG. 2, a planar state in which the folds at the virtual lines VL1, VL2, VL3, and VL4 are developed is referred to as an “expanded state”.
More specifically, as shown in the right half of FIG. 3A, the folded state of the tape 6 with the skin side inward at the width direction end of the main body 100 is referred to as a “first folded state”. (First state) ". Also, as shown in the left half of FIG. 3A and FIG. 3B, a state where the virtual lines VL1 and VL2 are folded and a state where the virtual lines VL3 and VL4 are not folded is referred to as a “second folded state (second state)”. Called. In the second folded state, the extended portion 61B in the first folded state is folded so as to face the side sheet 13 and be superposed. Further, a state of being folded along the virtual lines VL1, VL2, VL3, and VL4 as shown in FIG. 3C is referred to as a “third folded state (third state)”.

使用 In this way, the user unfolds the diaper 1 while viewing it from the skin side in a plan view, and proceeds with the mounting work on the wearer. Design a patch 4 having light transmittance (a patch 4 using a transparent or translucent material), a patch 4 having the same design as the design unit 5, and a patch 4 having at least a part of the same design as the design unit 5. In the case where the diaper 1 is mounted on the diaper 1, visual confusion between the design part 5 and the patch 4 is likely to occur, so that the user who sees the diaper 1 in the third folded state shown in FIG. Have difficulty. That is, the user may not be able to determine the front and rear of the diaper 1 depending on the position of the patch 4. In the diaper 1 in the unfolded state, the front body 1A and the back body 1C have a shape which is line-symmetric or substantially line-symmetric with respect to a longitudinal center line CL2 (reference line, see FIG. 3), or Since the appearances of the design portions 5A and 5B are the same or similar to each other, it is difficult to distinguish the front and rear of the diaper 1 by simply viewing the diaper 1 in the deployed state from the skin side.

<First identification section>
Therefore, a pair of first identification portions 4C, 4C having different colors (second colors) from the surrounding colors when the diaper 1 in the unfolded state is viewed from the non-skin side are provided at both ends in the width direction of the patch 4. Provided. Specifically, the colors of the first identification sections 4C and 4C are different from the colors of the overlapping section 4A of the patch 4 and the main body 100. As described above, the pair of first identification portions 4C, 4C located at both ends in the extending direction of the patch 4 have substantially the same color. On the other hand, the overlapping portion 4A of the patch 4 integrally forms the appearance of the front design portion 5A.

In the diaper 1 having such an aspect, when the folding process is performed along the virtual lines VL1 and VL2, the first identification portions 4C and 4C can be visually recognized when viewed from the skin side in a plan view (see FIG. 3B). Therefore, the first identification sections 4C, 4C can be used as markers for determining whether or not the folding process has been performed at an appropriate position. That is, by detecting the positions of the first identification units 4C and 4C by the marker recognizing means, the diaper that has been folded at an appropriate position and the diaper that has been folded at an inappropriate position can be distinguished. Can be determined. Examples of the marker recognizing means include a recognizing device using a reflection-type or transmission-type phototube, an imaging device using a CCD camera or a general camera, and the like. The diaper 1 folded in a predetermined shape can be efficiently manufactured by performing three-fold processing on the diaper 1 that has been folded at the above-described appropriate position using the virtual lines VL3 and VL4. As a result, the storage of the folded diaper 1 in the package is improved, and the productivity of the diaper 1 is excellent. The diaper that has been folded at an inappropriate position is expanded and the folding process is performed again.

<Fastening tape>
At least a part of the tape 6 has a similar color (second similar color) to the pair of first identification portions 4C, 4C. Specifically, the base sheet 61 and the locking member 62 have different colors, and the base sheet 61 or the locking member 62 and the first identification portions 4C, 4C have similar colors.
For example, in the tape 6, the base sheet 61 has a color similar to the main body 100 (first similar color), and the locking member 62 has a similar color (second color) to the pair of first identification portions 4C and 4C. (Similar colors). Alternatively, the base sheet 61 is a color similar to the pair of first identification portions 4C, 4C (second similar color), and the locking member 62 is a color similar to the main body 100 (first similar color). is there. That is, although it is difficult to distinguish one of the base sheet 61 and the locking member 62 from the main body 100 due to the difference in color, the other of the base sheet 61 and the locking member 62 is colored. It is preferable to use a configuration that can be easily distinguished by the difference between the two.
As described above, since the front and rear of the diaper 1 can be determined by the base sheet 61 or the locking member 62 of the second similar color, the user can quickly position the diaper 1 with respect to the wearer.
Note that it is difficult to adjust the color of the locking member 62 having a color different from white (so-called colored color), and there is a possibility that the manufacturing cost may increase. On the other hand, the locking member 62 of the same color as the white color of the main body 100 can be easily adjusted in color, and the base sheet 61 whose color can be easily adjusted compared to the locking member 62 is colored. Therefore, an increase in manufacturing cost can be suppressed.

{Circle around (1)} When the diaper 1 in the unfolded state is viewed from the non-skin side, the pair of first identification portions 4C, 4C has a color (second color) different from the surrounding color. Specifically, the colors of the first identification portions 4C and 4C are different from the colors of the overlapping portion 4A of the patch 4 and the main body 100.

Normally, the patches 4 are arranged symmetrically with respect to the center line CL1 in the width direction of the diaper 1 (see FIG. 1). By providing a pair of first identification portions 4C, 4C at both ends in the width direction W of the patch 4, the user exists between the center position of the diaper 1 and the pair of first identification portions 4C, 4C. The position of the patch 4 can be determined. Then, the user can guess the position of the diaper 1 from the position of the patch 4. Therefore, positioning of the diaper 1 with respect to the wearer is facilitated. In addition, when attaching the diaper 1, the tape 6 can be easily fixed to the patch 4, that is, the positioning of the tape 6 with respect to the patch 4 becomes easy.
Note that the patches 4 may be arranged asymmetrically with respect to the center line CL1. Even with the patches 4 arranged in this manner, the user can determine the position of the patches 4 by the pair of first identification units 4C, 4C. In the following, the “ first identification unit 4C, 4C” may be simply referred to as “first identification unit 4C”.

Further, since the base sheet 61 has a different color from the locking member 62, the user can easily grasp the position of the locking member 62 on the tape 6. In addition, since the base sheet 61 or the locking member 62 has a similar color to the first identification portions 4C, 4C, the user can easily visually understand that members having similar colors can be stopped. it can. Further, the user can easily determine the front and rear of the diaper 1 based on the positional relationship between the first identification sections 4C and 4C and the tape 6. Therefore, the user can quickly fix the tape 6 to the patch 4 existing between the first identification portions 4C, 4C, and wear the diaper 1 on the wearer with an appropriate fit.

The patch 4 extends outward in the width direction from the pair of virtual lines VL1 and VL2. By using the patch 4 in such an aspect, when the user unfolds the folded back of the main body 100 by the virtual lines VL3 and VL4 in the diaper 1 in the storage state (see FIG. 3C), The first identification portions 4C, 4C can be visually recognized in a plan view from the skin side. Further, when the diaper 1 in the deployed state is viewed from the non-skin side, the first identification portions 4C, 4C can be visually recognized. In other words, when the diaper 1 in the folded state is viewed from the non-skin side, the design portions 5A and 5B are visible, but the first identification portions 4C and 4C are not visible. When the folded diaper 1 is viewed from the skin surface side, the first identification portions 4C, 4C are visible, but the design portions 5A, 5B are not visible. Therefore, a user who looks at the diaper 1 in the folded state from the skin side or a user who looks at the diaper 1 in the unfolded state from the non-skin side can estimate the front and rear of the diaper 1 by determining the position of the patch 4. .
Therefore, the user can quickly position the diaper 1 with respect to the wearer.
In addition, when the diaper 1 in the folded state is viewed from the non-skin side, since the first identification portions 4C and 4C are not visible, the design when the diaper 1 in the folded state is viewed from the non-skin side. The decorativeness of the parts 5A and 5B can be ensured.

(4) The method for forming the first identification portion 4C is not particularly limited. For example, the first identification portion 4C can be formed by performing a printing process on the patch 4.

The base sheet 61 may have a single color or two or more colors as long as the base sheet 61 has a color different from that of the locking member 62. Similarly, the locking member 62 may be a single color or have two or more colors. When the base sheet 61 and / or the locking member 62 have two or more colors, the colors that occupy the widest area in plan view may be different from each other.

<Color and translucency of fastening tape>
Furthermore, when the diaper 1 is viewed from the skin surface side, the tape 6 has a predetermined translucency that allows the color (color) of the tape 6 to be transparent.
Hereinafter, the color of the tape 6 will be described, and thereafter, the predetermined translucency will be described.

(Color of fastening tape)
The tape 6 is at least partially different in color from the color of the main body 100. Here, the main body 100 having substantially the same white color over the entire region is taken as an example, and the tape 6 having the color patterns 1 and 2 shown below is exemplified.

――Color pattern 1――
In the color pattern 1, the colors of the respective parts are combined as shown below.
-Base material sheet 61: Color similar to the color (first color) of main body 100 (first similar color)
Locking member 62: a color different from the color of main body 100 (third color)
――Color pattern 2――
In the color pattern 2, the colors of the respective parts are combined as shown below.
The base sheet 61: a color in which the inner layer surface 61b on the side where the locking member 62 is laminated is different from the color of the main body 100 (third color)
Locking member 62: a color similar to the color (first color) of main body 100 (first similar color)
The portion (main portion) 61 a of the base sheet 61 excluding the inner layer surface 61 b is a color similar to the color of the main body 100 (first similar color).

Here, “substantially the same color (color)” means that all of brightness, hue, and saturation are substantially the same. In other words, "substantially the same color" means that even when the colors to be compared are not completely the same, the colors to be compared can be visually distinguished under sunlight or normal illumination light. It has a difficult degree of identity.
“Similar colors (colors)” means colors of the same type including substantially the same colors, that is, colors having the same or similar hues.
“Different colors (colors)” means that at least one of brightness, hue, and saturation is different. For example, not only those having different hues but also those having the same saturation but different saturation or lightness are “different colors”.

For example, it can be obtained by performing colorimetry using a commercially available colorimeter and comparing values quantified based on the CIE1976 (L ^* a ^* b ^* ) color space specified in JIS Z 8729 and the like. . Specifically, the difference in L ^* value between two points to be measured (for example, the color point of the main body 100 and at least a part of the color of the tape 6) is ΔL ^* , and the difference in a ^* value is Δa. ^When the difference between the ^* and b ^* values is Δb ^* , the color difference ΔE ^* ab = [(ΔL ^* ) ² + (Δa ^* ) ² + (Δb ^* ) ² ] ^1/2 is obtained. When the color difference ΔE ^* ab is preferably 1.5 or more, more preferably 3.0 or more, it can be said that the colors are different to the extent that the user can visually recognize them. In other words, the “different color” means that the color difference is within the above range. The “similar color” means that the color difference is preferably less than 1.5, and the “substantially the same color” means that the color difference is preferably less than 1.0.

<Specified translucency>
The “predetermined translucency” of the present embodiment is an optical property in which the third color of the tape 6 can be seen through when the diaper 1 in the first folded state or the second folded state is viewed from the skin side. Means properties. Hereinafter, two configurations having a predetermined light-transmitting property will be exemplified.
――First configuration example――
In the first configuration example, the translucency set in the diaper 1 of the color pattern 1 will be described.
The diaper 1 is set to have a predetermined translucency (hereinafter referred to as “first translucency”) in the first folded state. That is, the “first translucency” is a predetermined color in which the third color of the locking member 62 can be seen through the base sheet 61 from the skin side when the diaper 1 in the first folded state is viewed from the skin side. Means translucency.

The above-mentioned “first translucency” can be realized by the following three embodiments I to III.
-Aspect I: The total light transmittance of the base sheet 61 is 65 to 99%.-Aspect II: A plurality of through holes are provided in the base sheet 61.-Aspect III: The total light transmittance of the base sheet 61 is According to the base sheet 61 having the total light transmittance described in the embodiment I, the diaper 1 in the first folded state is viewed from the skin side. (When viewed from the side opposite to the side on which the locking members 62 are laminated with respect to the base sheet 61), the color of the locking members 62 is visible through the base sheet 61 in the thickness direction. is there.
The through-hole of Embodiment II has a circumscribed circle diameter of 0.1 to 1.0 [mm]. The base sheet 61 preferably has a plurality of through holes. For example, each through-hole is formed in a scattered point shape at intervals. Each of the through holes has a circular shape in plan view of the base sheet 61. However, a through hole having a polygonal shape in plan view of the base sheet 61 may be employed. The plurality of through holes are formed in a staggered arrangement pattern. According to such a through hole, when the diaper 1 in the first folded state is viewed from the skin surface side, the color of the locking member 62 is directly and partially visible through the through hole.
According to the film-shaped portion described in the aspect III, when the diaper 1 in the first folded state is viewed from the skin side, the color of the locking member 62 can be visually recognized through the film-shaped portion.

Furthermore, it is preferable that a predetermined translucency (hereinafter referred to as “second translucency”) when the diaper 1 is in the second folded state is set. The “second translucency” refers to a member (for example, the cover sheet 14) that is stacked closer to the skin than the locking member 62 and the inner surface 61 b when the diaper 1 in the second folded state is viewed from the skin. , Base portion 61A, side sheet 13) means a predetermined translucency in which the color of locking member 62 and inner layer surface 61b can be seen through.
The above-mentioned “second translucency” can be realized by the embodiment IV exemplified below.
Aspect IV: The total light transmittance of the cover sheet 14, the base 61A, and the side sheet 13 is 50 to 99%. According to the cover sheet 14, the base 61A, and the side sheet 13 having the total light transmittance described in the aspect IV, When the diaper 1 in the second folded state is viewed from the skin side, the colors of the locking member 62 and the inner layer surface 61b can be seen through.
The above “visible” means that the color of the locking member 62 can be perceived by the naked eye through the sheet laminated portion 50 from the skin side.

In the unfolded diaper 1 having such a configuration, the tape 6 is folded back on the manufacturing line at the width direction end of the main body 100 with the skin side facing inward, and the phantom lines VL1 and VL2 are used. When the portion of the main body 100 outside the imaginary lines VL1 and VL2 in the width direction is turned upside down, the locking member 62 or the inner layer surface 61b of the base sheet 61 when viewed from the skin side in a plan view. (See FIG. 3B). In other words, the color of the locking member 62 can be recognized through the sheet stacking portion 50 in a plan view from the skin side shown in FIG.
Therefore, the color of the locking member 62 and the inner layer surface 61b can be used as a marker for determining whether or not the folding process has been performed at an appropriate position. That is, by detecting the mutual position of the locking member 62 and the inner layer surface 61b of the tape 6 provided at both ends of the main body 100 by the marker recognition means, the diaper folded at an appropriate position can be It can be determined that the diaper has been folded at an inappropriate position. Examples of the marker recognizing unit include an optical recognizing unit such as a recognizing device using a reflection-type or transmissive-type phototube, and an imaging device using a CCD camera or a general camera. The diaper 1 folded in a predetermined shape can be efficiently manufactured by performing the tri-folding process using the virtual lines VL3 and VL4 on the diaper 1 that has been folded at the above-described appropriate position. As a result, the storage of the folded diaper 1 in the package is improved, and the productivity of the diaper 1 is excellent. The diaper that has been folded at an inappropriate position is expanded and the folding process is performed again.

Further, according to the diaper 1 of the present configuration, the user can start the diaper 1 in the third folded state (see FIG. 3C) in the second folded state in which the diaper 1 is folded back along the virtual lines VL3 and VL4 (see FIG. 3C). 3B), the color of the locking member 62 or the color of the inner layer surface 61b of the base sheet 61 can be visually recognized in a plan view from the skin side due to the second light-transmitting property described above. Further, in the first folded state in which the folding at the virtual lines VL1 and VL2 is developed from the second folded state (see the right half of FIG. 3A), the first light-transmitting property described above causes When viewed in a plan view, the color of the locking member 62 or the inner layer surface 61b can be visually recognized. Therefore, the user can estimate the front and rear of the diaper 1 by determining the positions of the locking member 62 and the inner layer surface 61b.
Therefore, the user can quickly position the diaper 1 with respect to the wearer.

The total light transmittance of the sheet laminated portion 50 is determined by selecting the material constituting each sheet (for example, the base sheet 61, the side sheet 13 and the cover sheet 14) (for example, when a nonwoven fabric is used, its fiber diameter [dtex]). (Decitex)], the basis weight thereof, the blending amount of filler [titanium oxide, etc.]), the thickness of each sheet, and the like.

When a nonwoven fabric is used as the material of each sheet constituting the sheet laminated portion 50 satisfying the total light transmittance in the above range, the fiber diameter is preferably 0.5 to 1.2 dtex, and the basis weight is 16 g. / M ² or less.
Here, the fiber diameter is obtained by dividing the sheet into approximately 5 equal parts in the width direction, sampling a 1 cm square test piece from each of the approximately five equally divided sheets, measuring the fiber diameter by 20 points each with a microscope. It can be calculated from the average value. The basis weight can be calculated by arbitrarily collecting five test pieces of 20 cm long by 20 cm wide from the sheet, measuring the mass, and converting the average value to the weight per unit area.

<Fastening tape>
When the base sheet 61 and the main body 100 are of the same color, the user unfolds the folded back of the main body 100 along the virtual lines VL3 and VL4 from the diaper 1 in the third folded state (see FIG. 3C). In the two-fold state (see FIG. 3B), it may be difficult to determine the position of the tape 6 when viewed from above the skin side. Even in such a mode, according to the diaper 1 having the above configuration, the user can estimate the front and rear of the diaper 1 by determining the position of the locking member 62 based on the color of the locking member 62.
Therefore, the user can quickly position the diaper 1 with respect to the wearer.
From the viewpoint of making it easier to determine the position of the locking member 62 and easily adjusting the total light transmittance of the sheet laminated portion 50, the total light transmittance of the base sheet 61 should be 65 to 99%. , And more preferably 75 to 99%.

When putting on the diaper 1, the user pulls the tape 6 to fix it to the patch 4. Therefore, it is preferable that the tape 6, especially the base sheet 61 bonded to the main body 100, have a predetermined tensile strength in the width direction W. Since the tensile strength of the base sheet 61 is adjusted by its thickness, in order to obtain the base sheet 61 having a predetermined tensile strength in the width direction W, the thickness tends to be large. On the other hand, when the thickness dimension of the base sheet 61 is increased, the total light transmittance of the base sheet 61 is reduced, and it tends to be difficult to adjust the total light transmittance of the sheet stacked unit 50. By providing a plurality of through holes in the base sheet 61, it becomes easy to obtain the base sheet 61 having an appropriate tensile strength and a predetermined total light transmittance.

The film-shaped portion is a portion where the constituent fibers (for example, synthetic resin fibers) of the base sheet 61 are thermally melted, lose the fiber form, and are formed into a film. The film-shaped portion can be formed by performing a heat and pressure treatment on the base sheet 61. The conditions of the heating and pressurizing treatment are appropriately set according to the constituent fibers of the base sheet 61.
The film portion has a higher total light transmittance than the base sheet 61 before being formed into a film. Therefore, by using the base sheet 61 having the film-shaped portion, the adjustment of the total light transmittance of the sheet laminated portion 50 becomes easy. In addition, when the diaper 1 is viewed in a plan view from the skin side in the first folded state, the visibility of the color of the locking member 62 is improved.

The meanings of the above terms are as follows.
“Substantially the same color” means that all of the brightness, hue, and saturation are substantially the same. In other words, "substantially the same color" means that even when the colors to be compared are not completely the same, the colors to be compared can be visually distinguished under sunlight or normal illumination light. It has a difficult degree of identity.

The “first identification unit 4C” is an area where the first identification unit 4C and other parts can be visually distinguished. More specifically, when the diaper 1 is unfolded (see FIG. 2), the first identification unit 4 </ b> C includes the front design unit 5 </ b> A and the main body in addition to the other parts of the patch 4 when viewed from the non-skin side. It has a color different from that of the portion 100 or a color different from other portions of the patch 4 and the main body 100.
Here, the "other part in the patch 4" refers to a part other than the first identification units 4C and 4C in the patch 4, and includes, for example, an overlapping part 4A and a non-overlapping part 4B. That is, when the diaper 1 in the unfolded state is viewed from the non-skin side in a plan view, the colors of the other portions of the patch 4 include the color of the overlapping portion 4A and the color of the non-overlapping portion 4B. In addition, the colors of the main body 100 when viewed in plan from the non-skin side include the colors of the design unit 5 and the colors of the main body 100 other than the design unit 5.
The “color of the front design part 5A” refers to a color that occupies the largest area when the front design part 5A is viewed in plan.
The “color of the design unit 5” refers to a color that occupies the largest area when the design unit 5 is viewed in a plan view.
In addition, the “color of the main body 100” may be described as a color mainly visible when the main body 100 is viewed in plan from the non-skin side (hereinafter, may be referred to as “non-skin side ground color”). ). Specifically, when the developed diaper 1 shown in FIG. 2 is viewed from the non-skin side, the color occupying the largest area in the main body 100 is referred to as the non-skin side ground color. Here, the main body 100 having substantially the same white color (first color) over the entire region will be described as an example. That is, white is exemplified as the ground color of the main body 100. However, in the main body 100 having two or more colors on the non-skin side, the color occupying the widest area in the main body 100 is the ground color.
For example, when the diaper 1 in the unfolded state is viewed in a plan view from the non-skin side, when all of the first identification unit 4C overlaps with the front design unit 5A, the first identification unit 4C uses the color of the overlap unit 4A and It has a color different from the color of the front design part 5A. When the front design part 5A and the first identification part 4C partially overlap, the first identification part 4C determines the color of the overlap part 4A, the color of the front design part 5A, and the ground color of the non-skin side. Has different colors. When the front design part 5A and the first identification part 4C do not overlap, the first identification part 4C has a color different from the color of the non-overlapping part 4B and the ground color of the non-skin surface side of the main body part 100.

“Different colors” means that at least one of brightness, hue, and saturation is different. For example, not only those having different hues but also those having the same hue but different chroma or lightness are “different colors”.
“Similar colors” means colors of the same type including substantially the same colors, that is, colors having the same or similar hues.

In addition, when the base sheet 61 has the same color as the main body 100 and the locking members 62 have the same color as the first identification portions 4C, 4C, the tape 6 passes through the base sheet 61 and the locking members 62. Is preferably seen through. Specifically, in the diaper 1 in the unfolded state, in a state where the locking member 62 is covered by the base sheet 61 from the non-skin side, the tape 6 is transparent through the second similar color of the locking member. It is preferable to have a predetermined translucency seen from the surface side.
This predetermined translucency can be realized by the following two examples V and VI.
-Aspect V: The total light transmittance of the base sheet 61 is 65 to 99%.-Aspect VI: The base sheet 61 is provided with a film-formed portion (film-formed portion).

In the base sheet 61 having the total light transmittance described in the aspect V, at least the base sheet 61 is transparent or translucent. According to the base sheet 61, when the diaper 1 in the folded state is viewed from the skin side (when viewed from the side opposite to the side on which the locking members 62 are stacked with respect to the base sheet 61), When the diaper 1 in the deployed state is viewed from the non-skin side, the color of the locking member 62 is visible through the base sheet 61 in the thickness direction.
According to the film-shaped portion described in the aspect VI, when the diaper 1 in the folded state is viewed from the skin side or the diaper 1 in the unfolded state is viewed from the non-skin side, the color of the locking member 62 is changed. Visible through the film.
The film-shaped portion is a portion where the constituent fibers (for example, synthetic resin fibers) of the base sheet 61 are thermally melted, lose the fiber form, and are formed into a film. The film-shaped portion can be formed by performing a heat and pressure treatment on the base sheet 61. The conditions of the heating and pressurizing treatment are appropriately set according to the constituent fibers of the base sheet 61.
The film portion has a higher total light transmittance than the base sheet 61 before being formed into a film. The film portion preferably has a total light transmittance of 65 to 99% from the viewpoint of securing a predetermined light transmittance. By using the base sheet 61 having such a film-shaped portion, the adjustment of the total light transmittance of the sheet laminated portion 50 becomes easy. In addition, when the diaper 1 is viewed in a plan view from the skin side in a folded state or when the diaper 1 is viewed in a plan view from a non-skin side in an unfolded state, the visibility of the color of the locking member 62 is improved.
The change rate of the total light transmittance before and after the film formation calculated by the following equation (1) is preferably 65 to 99%.
Change rate of total light transmittance before and after film formation [%]
= Total light transmittance after film formation / Total light transmittance before film formation × 100 (1)
In the above modes V and VI, the user can visually determine the position of the patch 4 by the color of the locking member 62 that can be seen through, and can also determine the front and rear of the diaper 1.

<Overlapping part>
In the patch 4 provided on the front design part 5A, the total light transmittance of the overlapping part 4A is preferably 65 to 99%. In the patch 4 in which the total light transmittance of the overlapping portion 4A is in the above range, at least the overlapping portion 4A is transparent or translucent. In such an aspect, visual confusion between the front design part 5A and the patch 4 is likely to occur, and the position of the patch 4 tends to be more difficult to determine. However, since the patch 4 has the first identification portions 4C and 4C at both ends in the width direction W, the user can easily determine the position of the patch 4.
Further, when the patch 4 having the total light transmittance of the overlapping portion 4A in the above range is used, even if the patch 4 is externally mounted on the front design portion 5A, the appearance of the front design portion 5A is hardly affected by the presence of the patch 4, and The visibility and appearance of the design section 5A are excellent. As a result, the user's willingness to purchase the diaper 1 can be increased.
The total light transmittance of the overlapping portion 4A is determined by selecting the material constituting the patch 4 (for example, in the case of using a nonwoven fabric, the fiber diameter [dtex (decitex)], the basis weight thereof, and the blending of filler [titanium oxide etc.] Amount), the thickness of the patch 4, and the like. When a nonwoven fabric is used as a material constituting the patch 4 that satisfies the total light transmittance in the above range, the fiber diameter is preferably 0.5 to 1.2 dtex, and the basis weight is preferably 16 g / m ² or less. The method for calculating the fiber diameter and the basis weight is as described above.

(4) The ratio of the area of the overlapping portion 4A to the area of the front design portion 5A is preferably 30 to 70%. By setting the ratio of the area of the overlapping portion 4A to the area of the front design portion 5A in the above range, the positioning when fixing the tape 6 to the patch 4 becomes easy, and the visibility and appearance of the design portion 5 are excellent. Therefore, the user can easily wear the diaper 1 on the wearer, and the user's willingness to purchase the diaper 1 can be improved.

In the case where the patch 4 is transparent or translucent, the overlapping portion 4A may have a color different from the color of the front design portion 5A. Since the color of the front design portion 5A is different from the color of the overlapping portion 4A, the position of the patch 4 can be easily determined.

<Relationship between patch and width dimension of design section>
Also, as shown in FIG. 2, the width dimension of the patch 4 is larger than the width dimension of the front design part 5A, and the first identification parts 4C, 4C are spaced outward from the front design part 5A in the width direction. . In other words, the patch 4 has a non-overlapping portion 4B that does not overlap with the front design portion 5A outside the overlapping portion 4A in the width direction. That is, the patch 4 of this aspect has the overlapping portion 4A, the non-overlapping portion 4B, and the first identifying portion 4C. The dimension in the width direction of the non-overlapping portion 4B is not particularly limited, but is preferable from the viewpoint of appropriately separating the first identification portions 4C, 4C from the overlapping portion 4A and improving the visibility of the first identification portions 4C, 4C. Is 5 mm or more, more preferably 10 mm or more, preferably 30 mm or less, more preferably 20 mm or less. However, the patch 4 is arranged inside the tape 6 in the width direction. In other words, the dimension of the patch 4 that is spaced apart from the center line CL1 in the width direction (see FIG. 1) in the width direction is shorter than that of the tape 6. Further, the first identification portions 4C, 4C are arranged on the inner side in the width direction with respect to the width direction end of the diaper 1.

According to the patch 4 in such an aspect, when the user unfolds the folded back of the main body 100 by the virtual lines VL3 and VL4 (see FIG. 3B), the user can use the skin on the diaper 1 (see FIG. 3C) in the storage state. The first identification portions 4C, 4C can be visually recognized in a plan view from the surface side. Further, the user can easily visually recognize the first identification portions 4C and 4C based on the color difference with the ground color on the non-skin surface side and the color difference with the non-overlapping portion 4B, so that the position of the patch 4 can be easily grasped.

For example, the color difference between the first identification units 4C and 4C and the ground color on the non-skin side is measured by using a commercially available colorimeter, and CIE1976 (L ^* a ^* b) specified in JIS Z 8729 and the like is performed. ^* ) It can be obtained by comparing values quantified based on the color space. Specifically, the difference in L ^* value between two points to be measured (the color of the first identification unit 4C and the ground color on the non-skin side) is ΔL ^* , and the difference in a ^* value is Δa ^* , b ^* value. Is Δb ^* , the color difference ΔE ^* ab = [(ΔL ^* ) ² + (Δa ^* ) ² + (Δb ^* ) ² ] ^1/2 . When the color difference ΔE ^* ab is preferably 1.5 or more, more preferably 3.0 or more, it can be said that the colors are different to the extent that the user can visually recognize them. In other words, the “different colors” means that the color difference is within the above range. The “similar color” means that the color difference is preferably less than 1.5, and the “substantially the same color” means that the color difference is preferably less than 1.0.
Here, the “color of the first identification unit 4C” refers to a color that occupies the largest area when the first identification unit 4C is viewed in a plan view.

<flap>
As shown in FIG. 6, the patch 4 has a pair of flaps 4D, 4D at both ends in the width direction. The flaps 4D, 4D are free ends formed at both ends of the patch 4. In the following, “flaps 4D, 4D” may be simply described as “flaps 4D”.
In FIG. 6, the flap 4D is provided at an end of the patch 4 together with the first identification unit 4C. According to the patch 4 having the flaps 4D at both ends in the width direction W, the user can determine the position of the patch 4 by touch.
The width dimension _{W 4D} flap 4D is not particularly limited. Discrimination tactile the width direction dimension W _4D flap 4D is too small it tends to become difficult. On the other hand, if the width dimension W _4D flap 4D is too large, the flap 4D when folding the diaper 1 in phantom lines VL1, VL2 may become causes of defects such as sandwiched device. In view of the above, the width dimension _{W 4D} flap 4D is preferably 1mm or more, more preferably 3mm or more, preferably 10mm or less, and more preferably 7mm or less. The longitudinal dimension of the flap 4D is substantially the same as the longitudinal dimension of the patch 4.

Also, from the viewpoint of making it easier to visually and tactually determine the position of the patch 4, the ratio of the width dimension W _4D of the flap 4D to the width dimension W _4C of the first identification portion 4C (W _4D / W _4C ). Is preferably at least 15%, more preferably at least 25%, preferably at most 50%, more preferably at most 40%.

<pattern>
Further, the patch 4 may have a pattern. When the pattern of the patch 4 is different from the pattern of the front design part 5A or the main body part 100 in a plan view from the non-skin side, the position of the patch 4 can be determined based on the pattern. Such a pattern can be formed by printing or embossing. The pattern may be formed on the entire patch 4 or on a part thereof. For example, a pattern can be formed only on the first identification portions 4C, 4C. From the viewpoint of facilitating the determination of the position of the patch 4, it is preferable to apply a pattern to the entire patch 4.

<Size>
The specific dimensions of the patch 4, the design unit 5, and the like are as follows.
The width dimension of the patch 4 is usually 100 mm or more, preferably 150 mm or more, and usually 250 mm or less, preferably 200 mm or less. The longitudinal dimension of the patch 4 is usually 20 mm or more, preferably 30 mm or more, and is usually 60 mm or less, preferably 50 mm or less. FIG. 2 shows the patch 4 having a width dimension of 180 mm and a longitudinal dimension of 40 mm.

The width dimension _{W 4C} of the first identification portion 4C is generally 5mm or more, preferably 10mm or more, typically 25mm or less, preferably 20mm or less. The longitudinal dimension of the first identification portion 4C is usually at least 20 mm, preferably at least 30 mm, and is usually at most 60 mm, preferably at most 50 mm. In FIG. 2, a pair of first identification portions 4 </ b> C having the same size in the longitudinal direction as the length of the patch 4 and colored in a region 15 mm inward in the width direction from the end of the patch 4. 4C is shown.

The width direction dimension of the design part 5 is usually 80 mm or more, preferably 100 mm or more, and usually 200 mm or less, preferably 150 mm or less. The length of the design portion 5 in the longitudinal direction is usually 80 mm or more, preferably 100 mm or more, and usually 200 mm or less, preferably 150 mm or less. FIG. 2 shows the design portions 5A and 5B each having a width dimension and a longitudinal dimension of 120 mm.

In the diaper 1 including the patch 4 and the front design part 5A having the above dimensions, visual confusion between the front design part 5A and the patch 4 tends to occur particularly easily. Therefore, by providing the first identifying portions 4C, 4C having the above dimensions at both ends of the patch 4, such confusion is reliably prevented, and the user can easily determine the position of the patch 4.

<Fixing part>
In addition, in the tape 6 exemplified here, the color of the base sheet 61 may be a color different from the white color of the main body 100 and may be a second similar color similar to the pair of first identification portions 4C and 4C. . On the other hand, the locking member 62 may be a color similar to the white color of the main body 100 (first color or first similar color). That is, although it is difficult to distinguish the locking member 62 from the main body 100 due to the difference in color, a configuration is adopted in which the base sheet 61 is easily distinguishable due to the difference in color.
For example, it is difficult to adjust the color of the locking member 62 having a color different from white (so-called colored color), which may increase the manufacturing cost. On the other hand, the locking member 62 of the same color as the white color of the main body 100 can be easily adjusted in color, and the base sheet 61 whose color can be easily adjusted compared to the locking member 62 is colored. Therefore, an increase in manufacturing cost can be suppressed.
However, the base sheet 61 has a color similar to the white color of the main body 100 (first color or first similar color), and the locking member 62 has a color different from the white color of the main body 100 (second color, second color). (Similar colors).

As described above, when at least a part of the tape 6 has a color (second color, second similar color) different from the white color of the main body 100, the rear body on which the tape 6 is arranged according to the color of the tape 6. 1C can be determined, and the front and rear of the diaper 1 can be determined. Furthermore, when the color of the tape 6 and the color of the first identification portions 4C and 4C of the patch 4 are similar colors, it is easy to determine where the tape 6 is fixed, which contributes to the improvement of the diaper 1's mounting property. .
Note that the tape 6 may be white (first color) over the entire area. In this case, although the front and rear of the diaper 1 cannot be determined by the color of the tape 6 as described above, a means for determining the front and rear of the diaper 1 by the color of the first identification unit 4C is secured, and Coloring cost can be suppressed.

<Modified color of the fastening part>
As a modification, at least a part of the tape 6 may have a color (fourth similar color) similar to the color (fourth color) of the design parts 5A and 5B. Specifically, in the tape 6, the base material sheet 61 has a fourth similar color similar to the design portions 5A and 5B.
Here, the colors (fourth color) of the design units 5A and 5B are the white color (first color) of the main body 100 described above, the color (second color) of the first identification unit 4C, and the third color of the tape 6. The color may be different from any of the colors. Alternatively, the fourth color may be the same color as any one of the first color, the second color, and the third color, or a color similar to any one of the first, second, and third colors. More preferably, the fourth color is a color different from the white color of the main body 100 from the viewpoint that the design portions 5A and 5B can be visually distinguished from the other portions.
By making at least part of the tape 6 a fourth similar color, when the tape 6 overlaps the front design portion 5A in a state where the locking member 62 is fixed to the cover sheet 14, the color of the tape 6 (the fourth color) Since the four similar colors match the color of the front design part 5A, the design of the design parts 5A and 5B is not hindered. In addition, the color of the tape 6 improves the visibility of the tape 6. That is, both the effect of improving the visibility of the tape 6 and the effect of suppressing design inhibition can be achieved.

(4) The visibility improving effect is particularly exhibited when the fourth similar color is a color different from the white color (first color) of the main body 100. In this case, in the tape 6, the base sheet 61 preferably has a fourth similar color, and the locking member 62 preferably has a first similar color. Since the locking member 62 is a first similar color (a color different from that of the base sheet 61), in addition to the effect of improving the visibility of the tape 6 and the effect of suppressing design inhibition, the locking member for the base sheet 61 is also provided. 62 is improved.

As another modified example, at least a part of the tape 6 may have a fifth color different from the second color of the first identification unit 4C. Since at least a part of the tape 6 is in the fifth color, the visibility of the tape 6 with respect to the first identification unit 4C is improved. From the viewpoint of improving the visibility of the tape 6, it is preferable that the fifth color of the tape 6 be a color different from the white color (first color) of the main body 100.

The fifth color of the tape 6 is, for example, a fourth similar color similar to the colors of the design units 5A and 5B. In this case, the color of the base sheet 61 (at least a part of the tape 6) is a fourth similar color similar to the colors of the design units 5A and 5B, and is different from the second color of the first identification unit 4C. It can be. Therefore, the effect of improving the visibility of the tape 6 and the effect of suppressing design inhibition are further exhibited.
Further, the color (second color) of the first identification unit 4C is preferably a lighter color than the color (fourth color) of the design units 5A and 5B. Here, the “light color” is, for example, a color having higher lightness and / or lower saturation than the fourth color. In this case, since the color of the first identification unit 4C is a light color, the design of the design units 5A and 5B is not disturbed, and a design inhibition suppressing effect is exhibited.

To summarize the above, the following combinations are exemplified as preferable combinations of colors of the main body 100, the first identification section 4C, the design sections 5A and 5B, the base sheet 61, and the locking members 62.
-The first color of the main body 100 is white,
The second color of the first identification unit 4C is different from the first color and the fourth color of the design units 5A and 5B, and is lighter than the fourth color;
The fourth color of the design units 5A and 5B is different from the first color in the first color and the second color of the first identification unit 4C;
The color of the base sheet 61 is a color (third color) different from the first color and is similar to the fourth color of the design units 5A and 5B (fourth similar color), and the color of the first identification unit 4C. It is a color different from the second color (fifth color),
The locking member 62 is a first similar color (a color different from the base sheet 61).
In this case, the effect of improving the discriminability of the tape 6 and the effect of suppressing the design inhibition are further exhibited.

As a modified example of the above combination, the color (second color) of the first identification unit 4C may be the same as the color (fourth color) of the design units 5A and 5B. In this case, the base sheet 61 (at least a part of the tape 6) has a fourth similar color similar to the color of the first identification portion 4C as well as the design portions 5A and 5B. Also in this combination, the effect of improving the discernability of the tape 6 and the effect of suppressing the design inhibition are exhibited.
As yet another modification, the base sheet 61 and the locking members 62 (all of the tape 6) may have a fourth similar color. Also in this case, the effect of improving the discernability of the tape 6 and the effect of suppressing the design inhibition are exhibited.

[2. Action and effect]
Since the diaper 1 of the first embodiment is configured as described above, it has the following operations and effects.
(1) According to the present invention, a novel absorbent article is provided.
(2) Even if the position of the patch 4 is difficult to determine due to the design portions 5A and 5B provided on the front body 1A and the back body 1C, respectively, the patch 4 has both ends in the width direction. The first identification portions 4C, 4C, the user can reliably determine the position of the patch 4. Further, the user can recognize the context of the absorbent article 1 from the position of the patch 4. Therefore, according to the present invention, it is easy to determine the position of the patch 4 and the front and rear of the absorbent article 1 with respect to the wearer, and it is easy to perform the positioning when fixing the fastening tape 6 to the patch 4.

[3. Others]
The above-described embodiment is merely an example, and there is no intention to exclude various modifications and application of technology not explicitly described in this embodiment. Each configuration of the present embodiment can be variously modified and implemented without departing from the spirit thereof. In addition, they can be selected as needed and can be appropriately combined.

For example, the location of the tape 6 (one of the front body 1A and the back body 1C) is not limited to the back body 1C but may be the front body 1A. In this case, the location of the patch 4 (the other of the front body 1A and the back body 1C) is the back body 1C. Then, in the above embodiment, "the front body 1A" may be read as "the back body 1C" and "the back body 1C" may be read as "the front body 1A".

(4) The first identification unit 4C may have the same design as the front design unit 5A. In the case of such an embodiment, the width of the patch 4 is made larger than the width of the design portion 5 and the first identification portion 4C is further separated from the front design portion 5A in the width direction, so that the patch 4 is used. This makes it easier for the user to visually recognize the first identification unit 4C, so that the position of the patch 4 can be determined.

[1. Constitution]
[1-1. Basic configuration]
The basic configuration of the tape-type paper diaper 300 will be described with reference to FIGS. In the cross-sectional view of FIG. 9, the thickness of each sheet is exaggerated for easy understanding of each configuration. In the following description, “tape-type paper diaper” is simply referred to as “paper diaper”.

In FIG. 7, the paper diaper 300 is formed symmetrically with respect to the center line A in the width direction. The disposable diaper 300 is roughly divided into three regions along the longitudinal direction: a front body 202, a crotch 203, and a back body 204. The front body 202 is an area located on the lower abdomen side of the wearer when worn. The back body 204 is an area located on the buttocks side of the wearer when worn. The crotch 203 is an area located between the front body 202 and the back body 204 and positioned at the wearer's crotch when worn.

The disposable diaper 300 includes a pair of left and right front side flaps 205 and a pair of right and left rear side flaps 206 extending from both longitudinal side edges outward in the width direction from the crotch portion 203 in the front body 202 and the back body 204. Each has.

Hereinafter, each component of the disposable diaper 300 will be described.

(Absorptive core)
The absorbent core 221 is a mat-shaped member that absorbs and holds a liquid. As shown in FIG. 9, the absorbent core 221 includes a superabsorbent polymer (SAP (superabsorbent polymer), also referred to as a superabsorbent polymer or a superabsorbent resin) 222 and a fiber material 223. . The absorbent core 221 is formed by mixing the superabsorbent polymer 222 with the fiber material 223. The fiber material 223 is formed by intertwining ultrafine fibers having hydrophilicity. The superabsorbent polymer 222 is usually buried and held in the fiber material 223 by being mixed with the fiber material 223. The superabsorbent polymer 222 can absorb and retain the liquid diffused by the fiber material 223.

<Super absorbent polymer>
As the superabsorbent polymer 222, various known polymers used as a material of an absorbent in an absorbent article such as a disposable diaper or a urine pad can be used. Examples of the superabsorbent polymer 222 include starch-based polymers such as starch-acrylic acid (salt) graft copolymer, saponified starch-acrylonitrile copolymer, and saponified starch-ethyl acrylate graft copolymer; Cellulose-based ones such as cross-linked carboxymethylcellulose; synthetic polymer-based ones such as polyacrylic acid (salt), polyethylene oxide cross-linked with acrylic acid, and cross-linked products of polyvinyl alcohol-maleic anhydride reactant can be used. Among these, from the viewpoint of absorbability, polyacrylic acid (salt) is preferred, and sodium polyacrylate is more preferred. These may be used alone or in combination of two or more. Although the shape of the superabsorbent polymer 222 is not particularly limited, for example, a granular, powdery, pellet, sol, film, fibrous, or the like can be used.

<Fiber material>
Examples of the fiber material 223 include cellulosic fibers such as pulp fiber, rayon fiber, and cotton fiber; and synthetic fibers such as polyethylene, polypropylene, and polyethylene terephthalate that have been subjected to a hydrophilic treatment. Above all, from the viewpoint of absorbability, it is preferable to use fluff pulp obtained by pulverizing or fibrillating fibers or synthetic fibers. These may be used alone or in combination of two or more.

〔Absorber〕
The absorber 220 is a liquid-absorbing mat-like (or pad-like) member that absorbs and retains liquid moisture (hereinafter, “excreted moisture”) such as urine and menstrual blood excreted from the wearer. As shown in FIG. 7, in the present embodiment, an hourglass-shaped absorber 220 in which the crotch 203 has a smaller width dimension than the front body 202 and the back body 204 is illustrated. More specifically, this absorptive body 220 has an asymmetric hourglass in which a longitudinal dimension of a portion of the back body 204 having a large width direction is larger than a longitudinal dimension of a portion of the front body 202 having a large width direction. It has a shape. However, the shape of the absorber 220 in plan view is not limited to the hourglass shape as described above, and may be rectangular (that is, the width direction dimension is constant) in plan view, or may be circular front and back bodies 202 and 204, respectively. May be in a dumbbell shape.

吸収 As shown in FIG. 9, the absorber 220 has an absorbent core 221 and a core wrap sheet (hereinafter abbreviated as “wrap sheet”) 224. The absorber 220 is formed by encapsulating (wrapping) the absorbent core 221 with a wrap sheet 224. The wrap sheet 224 covers the entire absorbent core 221 including the skin facing surface side and the non-skin facing surface side of the absorbent core 221.

<Wrap sheet>
The wrap sheet 224 is a sheet-like member that covers the absorbent core 221. By covering the absorbent core 221 with the wrap sheet 224, the fixed shape of the absorbent core 221 is ensured.

The wrap sheet 224 can be formed of a known material used for an absorbent article. For example, paper such as tissue paper; spunbonded nonwoven fabric, needle-punched nonwoven fabric, spunlace nonwoven fabric, air-through nonwoven fabric, SMS (Spunbound @ Meltblown @ Spunbound) nonwoven fabric and the like can be used.

(Laminate)
The laminated body 210 is a laminated structure in which a top sheet 231 and a back sheet 232 are arranged on both main surfaces of the absorber 220, respectively. Among them, the top sheet 231 is arranged on the surface of the absorber 220 on the skin facing surface side. The back sheet 232 is disposed on the surface of the absorber 220 on the non-skin facing side. The laminated body 210 allows the excreted moisture from the skin-facing surface side to pass through the top sheet 231, absorbs and retains the permeated excreted moisture by the absorber 220, and leaks to the outside from the non-skin-facing surface side by the back sheet 232. To block. The top sheet 231 and the back sheet 232 and the absorber 220 can be fixed with a known adhesive such as a hot melt adhesive.

<Top sheet>
The top sheet 231 is a sheet-like member arranged on the side of the laminate 210 closest to the skin. The top sheet 231 has a larger width dimension than the absorber 220 and covers the entire surface of the absorber 220 from the side facing the skin. The top sheet 231 is in contact with the wearer's skin in a state in which the disposable diaper 300 is attached, and allows excreted moisture to permeate and be absorbed by the absorber 220. For this reason, the top sheet 231 is at least partially or entirely made of a material having water permeability. Further, it is preferable that the top sheet 231 be made of a material having high flexibility for fitting at the time of mounting. In addition, in order to suppress stuffiness in the mounted state, it is preferable that the material is formed of a material having air permeability.

材料 As a material forming the top sheet 231, for example, a woven fabric, a nonwoven fabric, a porous film, or the like can be used. Alternatively, as the top sheet 231, a non-woven fabric obtained by subjecting fibers of a thermoplastic resin such as polypropylene, polyethylene, polyester, or nylon to a hydrophilic treatment may be used. As the nonwoven fabric forming the top sheet 231, for example, a spunbonded nonwoven fabric, a needle punched nonwoven fabric, a spunlace nonwoven fabric, an air-through nonwoven fabric, a melt blown nonwoven fabric, an SMS nonwoven fabric, and the like can be used.

<Back sheet>
The back sheet 232 is a sheet-shaped member disposed on the side of the laminate 210 closest to the skin. The back sheet 232 has a larger width dimension than the absorber 220 and the top sheet 231 and covers the entire surface of the absorber 220 and the top sheet 231 from the non-skin-facing surface side. Further, the back sheet 232 prevents excrement from leaking from the absorber 220 to the non-skin-facing surface side. For this reason, the back sheet 232 is made of a material having water impermeability. Further, it is preferable that the back sheet 232 be made of a material having moisture permeability in order to suppress stuffiness in a mounted state.

(4) As a material forming the back sheet 232, for example, a thermoplastic resin sheet such as polyethylene or polypropylene can be used. Above all, as the back sheet 232, it is preferable to use a microporous thermoplastic resin sheet in which a plurality of fine holes of 0.1 to 0.4 μm are formed. As such a sheet, for example, a sheet obtained by kneading an inorganic filler into a thermoplastic resin, forming the sheet, and then stretching the sheet can be used.

[Side sheet, cover sheet]
The disposable diaper 300 further includes a side sheet 233 and a cover sheet 235 laminated on the laminated body 210. The side sheet 233 is arranged from the side in the width direction of the laminated body 210 to the skin facing surface side. The cover sheet 235 is arranged on the non-skin facing side of the laminate 210. The side sheet 233, the cover sheet 235, and the laminate 210 can be fixed with a known adhesive such as a hot melt adhesive.

<Side seat>
The side sheets 233 are a pair of left and right members provided on both sides in the width direction to form three-dimensional gathers 242 described later on both sides of the laminated body 210. As shown in FIG. 8, the side sheet 233 includes a flap portion 234A and a flap portion 234B that extend outward in the width direction beyond the crotch portion 203 from both longitudinal edges in the front body 202 and the back body 204, respectively. Have. As shown in FIG. 9, the side sheets 233 are provided on each of the width direction sides of the top sheet 231 and the back sheet 232. Furthermore, the side sheet 233 is laminated on the skin facing surface side from the width direction side of the top sheet 231 and the back sheet 232 to the width direction side portion. The side sheet 233 stands up in the direction in which it comes into contact with the wearer's skin by utilizing the contraction of the three-dimensional gather 242 described later.

The side sheet 233 is preferably made of a water-impermeable material in order to prevent liquid leakage to the side in the width direction. As the side sheet 233, a spunbonded nonwoven fabric can be used. In addition, a part of the side sheet 233 is disposed on the skin-facing surface side in the disposable diaper 300 (for this reason, the side sheet 233 is also referred to as a “top sheet” like the top sheet 231). As the side sheet 233 that can be brought into contact with the wearer, a spunbonded nonwoven fabric having increased flexibility by including a melt blown layer such as an SMS nonwoven fabric or an SMMS (Spunbound Meltblown Meltblown Spunbound) nonwoven fabric is used. Is preferred. Alternatively, it is preferable to use a spunbonded nonwoven fabric having improved flexibility by suppressing the fineness and the basis weight of the fibers constituting the spunbonded nonwoven fabric.

The “fineness” is a parameter corresponding to a fiber diameter (thickness) or a cross-sectional area of the fiber, and is represented by a weight per a predetermined length. For example, the number of grams per 10,000 m (decitex) of one fiber is used as “fineness”.
The “weight per unit area” is a parameter corresponding to the thickness or the degree of lamination of the sheet, and is represented by a weight per unit area. For example, the number of grams per square meter is used as the “basis weight”.

<Cover sheet>
The cover sheet 235 is a sheet-like member that covers the laminate 210 from the non-skin-facing surface side. The cover sheet 235 is used to reinforce the back sheet 232 and improve the feel (tactile sensation) of the back sheet 232 by being disposed on the most non-skin-facing side except the patch 238 in the disposable diaper 300. Can be The cover sheet 235 has a larger width dimension than the absorber 220, the top sheet 231, and the back sheet 232, and is arranged around the wearer's inseam, buttocks, hips, waist, belly, and the like in the mounted state. As shown in FIG. 8, the cover sheet 235 includes a pair of left and right flap portions 236 </ b> A and a left and right Each has a pair of flap portions 236B.

材料 As a material for forming the cover sheet 235, for example, a woven fabric, a nonwoven fabric, or the like can be given. Among them, it is preferable to use a nonwoven fabric or a wet nonwoven fabric of a thermoplastic resin such as polyethylene, polypropylene, and polyester. In particular, a spun bond nonwoven fabric can be suitably used as the cover sheet 235 from the viewpoint of flexibility in order to secure a tactile sensation (touch).

The cover sheet 235 is usually a translucent sheet. Specifically, the cover sheet 235 has a total light transmittance of preferably 65% or more, more preferably 75% or more, preferably 99% or less, more preferably 90% or less. When the total light transmittance of the cover sheet 235 is equal to or more than the lower limit, the second identification portions 280a and 280b and the design portions 291 and 292 are easily visible through the cover sheet 235 from the non-opposite surface of the disposable diaper 300. When the total light transmittance of the cover sheet 235 is equal to or less than the above upper limit, the back sheet 232, the second identification portions 280a and 280b, and the design portions 291 and 292 may be in contact with or rubbing with other members. It is easier to be protected.

In the present specification, the “total light transmittance” is measured by a measuring method based on JIS K 7361-1 (Plastic—Testing method for total light transmittance of transparent material—Part 1: Single beam method). Value. When the cover sheet 235 is a nonwoven fabric, the total light transmittance can be adjusted by the fineness and basis weight of the nonwoven fabric, or the content of a filler such as titanium oxide.

In the disposable diaper 300 configured as described above, the respective members are laminated in the order of the side sheet 233, the top sheet 231, the absorber 220, the back sheet 232, and the cover sheet 235 from the skin facing surface side to the skin non-facing surface side. Have been. The side sheet 233 and the cover sheet 235 are attached to each other with a known adhesive such as a hot melt adhesive. Then, the front side flap 205 is formed by the flap portion 234A and the flap portion 236A. Further, the rear side flap 206 is formed by the flap portion 234B and the flap portion 236B.

The main body 201 (see FIG. 7) of the disposable diaper 300 extends over the front body 202, the crotch 203, and the back body 204 such as the absorber 220, the sheets 231 to 233, 235 and the flaps 234A, 234B, 236A, 236B. It has a basic member provided. Note that the patch 238, the tape 260, the second identification units 280a and 280b, and the design units 291 and 292 are additional components (not basic members) and are not included in the main unit 201.

〔patch〕
The patch 238 constitutes a fastening mechanism that realizes a fastening function together with the tape 260, and is a loop member to which the tape 260 can be attached. The tape 260 and the patch 238 constitute a fastening mechanism. As the fastening mechanism, for example, a planar fastener (mechanical fastener) having at least a hook member (male member) and mechanically coupled by the hook member and a loop member (female member) can be used. The hook member is a sheet-shaped member having a large number of protrusions such as hooks, mushrooms, and anchors formed on the surface. Further, the loop member is a sheet-like member using a non-woven fabric having loop-like fibers disposed on the surface or made of short fibers. Alternatively, an adhesive or an adhesive tape can be used as the fastening mechanism. Among them, a planar fastener is preferable because the hook member and the loop member can be firmly fixed, and they can be peeled off and used repeatedly. In the present embodiment, a case where the tape 260 functions as a hook member and the patch 238 functions as a loop member will be exemplified.

In the present embodiment, a front patch (hereinafter abbreviated as “patch”) 238 is attached to the outer surface of the front body 202 of the cover sheet 235 (the non-skin-facing surface of the laminate 210). As the patch 238, for example, a nonwoven fabric using fibers of a thermoplastic resin such as polypropylene, polyethylene, polyester, and nylon is used.

〔tape〕
The tape 260 forms a fastening mechanism together with the patch 238 and has a hook member that can be attached to the patch 238. The tape 260 is attached to at least one of the front side flap 205 and the rear side flap 206 so as to protrude outward in the width direction. In the present embodiment, a case where the tape 260 is provided on the rear side flap 206 is exemplified. When the disposable diaper 300 is bent toward the skin-facing surface with the front body 202 and the back body 204 facing each other with the crotch 203 as the center, the tape 260 is pulled outward in the width direction and is fixed to the patch 238. . Then, in this state, the disposable diaper 300 is worn on the wearer.

As shown in FIGS. 7 and 8, the tape 260 is fixed to the rear side flap 206 and has a sheet-like fastening portion 261 extending outward from the rear side flap 206. Further, a locking member 264 serving as a hook member for fixing the front body 202 and the back body 204 is provided on one main surface of the fastening portion 261. The fastening portion 261 can stop the front body 202 and the rear body 204 via the locking member 264 and the patch 238.

The fastening part 261 has a base part 262 on the inner side in the width direction, and a protruding part 263 protruding outward from the base part 262 in the width direction. The base portion 262 is fixed to the rear side flap 206 by being narrowed between the flap portions 234B and 236B. The protruding portion 263 protrudes outward in the width direction from the side sheet 233 and the cover sheet 235 and is provided in a state of being exposed to the outside. A locking member 264 is provided on the side of the protruding portion 263 facing the skin.

材料 As a material of the fastening portion 261 of the tape 260, for example, a woven fabric, a nonwoven fabric, a resin film, paper, or the like can be used. As a material constituting the woven fabric, the nonwoven fabric, or the resin film, for example, a thermoplastic resin such as polyethylene, polypropylene, polyamide, polyester, polyvinyl chloride, and polystyrene can be used.

〔gather〕
The disposable diaper 300 is provided with gathers 240 such as leg gathers 241, three-dimensional gathers 242, and waist gathers 243 in order to enhance the ability to follow the wearer in the worn state. The gathers 240 are formed by sandwiching a stretchable member (stretchable member) such as rubber, polyurethane, or a stretch film between stretched sheets of nonwoven fabric or the like, and fixing the stretchable member by hot melt, heat sealing, ultrasonic welding, or the like. It is composed of an elastic sheet composite. The sheet composite is in a state in which the sheet has fine wrinkles due to the force (restoring force, elastic force) of the elastic member returning from the stretched state to the original state (natural length state). Here, a thread-like rubber member (hereinafter, abbreviated as “thread rubber”) 250 is exemplified as the elastic member.

In the disposable diaper 300, as the gathers 240 formed by the thread rubber 250, three kinds of gathers 241, 242, 243 provided with elasticity by three kinds of thread rubbers 251, 252, 253 are exemplified. One is a leg gather 241 in which the widthwise outer edge of the back sheet 232, the side sheet 233, and the cover sheet 235 are wrinkled by the first thread rubber 251. The other is a three-dimensional gather 242 in which the widthwise inner edge of the side sheet 233 is wrinkled by the second thread rubber 252. The other is a waist gather 243 in which the longitudinally rear edges of the top sheet 231, the back sheet 232, the side sheet 233, and the cover sheet 235 are wrinkled by the third thread rubber 253.

The ギ ャ leg gathers 241 are provided in order to increase the follow-up of the wearer's legs and suppress the gap with the disposable diaper 300. As shown in FIG. 7, the leg gathers 241 are provided at locations where the legs become peripheral edges of the wearer in the mounted state. As shown in FIGS. 7 and 8, in the leg gather 241, the first thread rubber 251 is provided along the longitudinal direction at the outer edge in the width direction of the back sheet 232 in the crotch portion 203 and the periphery thereof. ing. As shown in FIG. 9, the first thread rubber 251 is interposed between the side sheet 233 and the cover sheet 235.

The three-dimensional gathers 242 are provided in order to prevent the excrement from leaking laterally in the width direction by improving the followability to the wearer at the periphery of the excretion point. As shown in FIG. 7, the three-dimensional gathers 242 are arranged inside the side sheets 233 in the width direction. As shown in FIGS. 7 and 8, in the three-dimensional gather 242, the second thread rubber 252 is provided along the longitudinal direction at the widthwise inner edge of the side sheet 233. Further, as shown in FIG. 9, in the three-dimensional gather 242, the sheet portions 233 </ b> A and 233 </ b> B located at the inner edge in the width direction of the side sheet 233 are folded and overlapped. The second thread rubber 252 extending in the longitudinal direction is surrounded by these sheet portions 233A and 233B.

The waist gather 243 is provided to enhance the ability to follow the buttocks and lower abdomen of the wearer. More specifically, in the waist gather 243, a stretchable sheet 254 in which a plurality of third thread rubbers 253 extending in the width direction are stretched and narrowly mounted on a set of non-stretchable base sheets is used. As shown in FIGS. 7 and 8, the elastic sheet 254 is interposed between the top sheet 231 and the cover sheet 235 at the longitudinally rear edge.

[1-2. Detailed configuration]
Next, a detailed configuration of the disposable diaper 300 will be described.

(Second identification unit)
As shown in FIGS. 7 and 8, the disposable diaper 300 includes a pair of second identifications that can be visually identified from the non-skin-facing surface side at a central position in the longitudinal direction and a symmetrical position in the width direction in the crotch 203. Parts 280a and 280b are provided, respectively. Here, the second identification units 280a and 280b printed on the back sheet 232 are illustrated. In the present specification, when the second identification units 280a and 280b are not particularly distinguished from each other, they may be described with “2nd identification unit 280” with reference numerals. As shown in FIG. 10, the second identification unit 280 functions as a marker for recognizing the longitudinal center positions of the backsheet 232 and the disposable diaper 300. Further, the second identification unit 280 is attached by bending the paper diaper 300 in the longitudinal direction around the second identification unit 280, so that the second identification unit 280 is located at the lowermost part of the paper diaper 300. It functions as a marker for allowing the user to recognize that the lengths from the bottom to both ends in the longitudinal direction are substantially the same. In the present specification, the lowermost portion refers to a portion located at the lowest position in the disposable diaper 300 when the wearer of the disposable diaper 300 stands upright with the direction of gravity acting downward. The second identification unit 280 also functions as a marker for controlling the cutting position of the sheet when a plurality of back sheets 232 are cut out from a long sheet and manufactured.

The second identification unit 280 is not particularly limited as long as it is visually distinguishable from a portion other than the second identification unit 280, but usually has a color different from that of the back sheet 232. Here, the main body 201 including the back sheet 232 is substantially the same white (color) over the entire area. Therefore, the color of the second identification unit 280 is not particularly limited, but is preferably other than white because the main body 201 is substantially the same white (color) over the entire area. For example, red, orange, yellow, green, Light blue, blue, purple, gray, black, etc. The second identification unit 280 may have a character, a graphic, a symbol, a pattern, or a combination thereof in a color different from those of the other parts. In the present embodiment, as shown in FIGS. 7 and 10, the second identification unit 280 is provided as an oval figure.

In the second embodiment, “substantially the same color” means that the color difference is preferably less than 1.0. "Different colors" means that the color difference is preferably 1.5 or more, more preferably 3.0 or more. The term "color difference" used herein refers to a method of measuring color using a commercially available colorimeter and comparing values quantified based on a CIE1976 (L ^* a ^* b ^* ) color space defined in JIS Z 8729 or the like. Can be obtained by: Specifically, when the difference in L ^* value between two points to be measured is ΔL ^* , the difference in a ^* value is Δa ^* , and the difference in b ^* value is Δb ^* , the color difference ΔE ^* ab = [( ΔL ^* ) ² + (Δa ^* ) ² + (Δb ^* ) ² ] ^1/2 . When the color difference ΔE ^* ab is preferably 1.5 or more, more preferably 3.0 or more, it can be said that the colors are different enough to be visually perceivable by the user, and preferably less than 1.0. It can be said that the colors are substantially the same to the extent that the user cannot visually recognize them.

The second identification unit 280 can be formed, for example, by printing ink of a desired color by a printing method such as letterpress printing, gravure printing, flexographic printing, offset printing, screen printing, or inkjet printing. The ink may be water-based or oil-based, but usually oil-based ink is used. The ink contains a known dye or pigment as a coloring material, a solvent, a surfactant, and the like. Further, the ink may contain a fluorescent material or a phosphorescent material.

第二 The second identification portion 280 is provided on the non-skin-facing surface side of the back sheet 232. Thereby, the second identification unit 280 is provided on the outermost layer on the non-skin-facing surface side of the laminate 210. The diaper 300 is located on the non-skin-facing surface side of the diaper 300 and is directed to the outside of the diaper 300 via the cover sheet 235 at the time of mounting.

The second identification portion 280 is provided on a side edge portion 232 </ b> A that is an outer edge in the width direction of the disposable diaper 300. As shown in FIG. 10, by providing the leg gathers 241, when the paper diaper 300 is mounted, the outer edge in the width direction of the crotch part 203 is creased by the first thread rubber 251, and the side edge The portion 232A is lifted above the center. Thus, the second identification unit 280 can be visually identified not only when the diaper 300 is viewed from below or obliquely below but also when viewed from the side.

[Design Department]
The design portions 291 and 292 are provided so as to be able to be viewed from the non-skin-facing surface side, and have, for example, characters, figures, symbols, patterns, or a combination thereof. Examples of the characters include hiragana, katakana, kanji, and the alphabet. The character may be a single character, a word composed of a plurality of characters, or a sentence composed of a plurality of words connected. Examples of figures include, for example, circles, triangles, squares, stars, other polygons, and figures in which a solid is illustrated on a plane. Examples of symbols include, for example, map symbols, weather symbols, mathematical symbols, pictograms, and the like. Examples of patterns include, for example, people, animals, plants, and characters, or patterns of these. The design units 291 and 292 can display a single character or a plurality of characters, graphics, symbols, and patterns, and can repeatedly display a plurality of them. In addition, the design units 291 and 292 can display characters, figures, symbols, and patterns in an overlapping manner. For example, with the figure as a background, the design units 291 and 292 can further display characters, figures, symbols, and patterns. The design units 291 and 292 may have the same characters, figures, symbols, patterns, and the like, or may have different same characters, figures, symbols, patterns, and the like. By providing the design units 291 and 292 on the disposable diaper 300, it is possible to attract, entertain, and delight a user such as a wearer of the disposable diaper 300 or a person who wears the disposable diaper 300. The design units 291 and 292 are used for positioning when the disposable diaper 300 is mounted. The design units 291 and 292 can be formed by printing, like the second identification unit 280.

As shown in FIGS. 7 and 10, the design units 291 and 292 are provided with a front design unit 291 (first design unit) of the front body 202 and a rear design unit 292 (second design unit) of the back body 204. And has a contour shape occupying a predetermined range. The proportion of the range occupied by the design portions 291 and 292 in the front body 202 and the back body 204 is not particularly limited, but is preferably 20% or more, more preferably 40% or more, further preferably 60% or more, and particularly preferably 70% or more. It is. The upper limit is not particularly limited, but is preferably 100% or less, more preferably 90% or less, and further preferably 80% or less. When the ratio of the range occupied by the design units 291 and 292 is equal to or more than the lower limit, visibility is increased, and a stronger impression can be given to a person who views the design units 291 and 292. Further, the shapes of the design units 291 and 292 can be easily grasped, and the positioning of the disposable diaper 300 using the design units 291 and 292 can be easily performed.

It is preferable that the length of the design portions 291 and 292 in the width direction is longer than the length in the longitudinal direction. Specifically, the design portions 291 and 292 preferably have a length in the width direction with respect to the length in the longitudinal direction of preferably 105% or more, more preferably 110% or more, further preferably 120% or more, and particularly preferably 140% or more. It is. The upper limit is not particularly limited, but is preferably 400% or less, more preferably 300% or less, and further preferably 200% or less. If the length in the width direction with respect to the length in the longitudinal direction of the design portions 291 and 292 is equal to or larger than the lower limit, the design portions 291 and 292 are widened, and the design portions 291 and 292 are compared with each other to compare their positions. Is easier to do. Therefore, when the disposable diaper 300 is mounted, it is easy to align the design portions 291 and 292 such that the heights of the design portions 291 and 292 substantially match each other. In this specification, the length in the longitudinal direction of the design portions 291 and 292 refers to the length in the longitudinal direction between the two furthest points in the longitudinal direction in each of the design portions 291 and 292. The length in the width direction of the design portions 291 and 292 refers to the length in the width direction between the two furthest points in the width direction in each of the design portions 291 and 292.

The design portions 291 and 292 have a length L ₃₁ from the longitudinal abdominal end 232B of the disposable diaper 300 to the distal end 291A (second crotch lower edge) of the front design portion 291 on the crotch 203 side (second crotch separation). Dimension) and the length L ₃₂ (first crotch separation dimension) from the longitudinal back end 232C to the end 292A (first crotch lower edge) of the rear design portion 292 on the crotch 203 side are the same. Or, they are arranged almost identically. Here, the end portions 291A and 292A are portions of the design portions 291 and 292 that protrude most toward the crotch portion 203 side.

Further, the design portions 291 and 292 have a length L ₂₁ from the longitudinal abdominal end portion 232B of the disposable diaper 300 to the terminal end portion 291B (second front and rear end edge) of the front design portion 291 opposite to the crotch portion 203. (Second front-rear separation dimension) and a length L ₂₂ (first front-rear end edge) from the rear end 232C in the longitudinal direction to the end 292B (first front-rear edge) on the opposite side of the crotch 203 of the rear design portion 292. Front-rear separation dimensions) are the same or substantially the same.

As described above, the longitudinal dimension (L ₃₁ -L ₂₁ ) of the front design part 291 and the longitudinal dimension (L ₃₂ -L ₂₂ ) of the rear design part 292 are set to be the same or substantially the same.
In the present specification, substantially the same length means that the length of one side relative to the other side is preferably within a range of ± 15%, more preferably within a range of ± 10%, and still more preferably ± 5%. It is within the range.

The design portions 291 and 292 are edges (edges along the width direction) of which the end portions 291A and 292A on the crotch portion 203 side are substantially parallel to the longitudinal ends 232B and 232C of the paper diaper 300, respectively. Here, the longitudinal ends 232 </ b> B and 232 </ b> C are generally linear, and are formed parallel to the width direction of the paper diaper 300 and the backsheet 232. The end portions 291A, 292A are preferably formed in a linear or curved shape such that the end portions 291A, 292A and the longitudinal ends 232B, 232C have a substantially parallel relationship. When the end portions 291A and 292A are formed in a curved shape, as shown in FIG. 7, the central portions of the end portions 291A and 292A extend toward the crotch portion 203 side from the both end portions and bulge. It is preferable that the shape is symmetrical. In the present specification, the end portions 291A and 292A are substantially parallel to the longitudinal ends 232B and 232C, respectively. The angle between the edge of each of the portions 232B and 232C is preferably in a range of 90 ° ± 20 °, more preferably in a range of 90 ° ± 10 °, and further preferably in a range of 90 ° ± 5 °. . However, when the shapes of the end portions 291A and 292A are linear, the angle between the straight lines forming the end portions 291A and 292A is 90 °.

The appearance of the design units 291 and 292 of the present embodiment is the same or similar to each other. The “ design portions 291 and 292 having the same or similar appearance” here include at least one of modes 1 to 4 listed below.
-Aspect 1: Design parts 291 and 292 with the same or similar color or pattern
-Aspect 2: Design parts 291 and 292 with the same or similar pattern arrangement
-Aspect 3: Design portions 291 and 292 having the same or substantially the same width dimension.
Aspect 4: Design portions 291 and 292 having the same or substantially the same longitudinal dimension
For example, design portions 291 and 292 having an external appearance that is line-symmetric or substantially line-symmetric in the longitudinal direction are provided.

In addition, the disposable diaper 300 is shipped in a folded state. More specifically, a pair of virtual lines VL5 and VL6 (bent curves) virtually extending in the longitudinal direction orthogonal to the width direction at both ends in the width direction of the absorber 220, with the skin surface side inside and virtual A portion outside the line VL5 and VL6 in the width direction is folded back. The state folded in this manner is referred to as a “folded state”. In the folded diaper 300, the first surface in the width direction outside the pair of virtual lines VL5 and VL6 faces and overlaps the second surface in the width direction inside the pair of virtual lines VL5 and VL6. Can be
That is, when using the folded paper diaper 300 at the time of product shipment, the user expands the folding by the virtual lines VL5 and VL6 in the longitudinal direction, and then wears the paper diaper 300 on the wearer. The state in which the disposable diaper 300 is unfolded in a planar manner in this manner is referred to as an “unfolded state”.

紙 In the disposable diaper 300 of the present embodiment, the second identification unit 280 is arranged outside the virtual lines VL5 and VL6 in the width direction. Note that “outside the virtual lines VL5 and VL6 in the width direction” here means that at least a part of the second identification unit 280 is located outside the virtual lines VL5 and VL6 in the width direction. Therefore, the whole of the second identification unit 280 may be disposed outside the virtual lines VL5 and VL6 in the width direction, or may extend across the virtual lines VL5 and VL6 in the width direction.

[2. Action and effect]
Since the disposable diaper 300 of the present embodiment is configured as described above, the following operations and effects can be obtained.

Conventionally, patterns provided on disposable diapers appeal mainly to the emotions of the wearer and user, and do not serve a functional role. Further, a marker for controlling the cutting position provided on the sheet has been provided for that purpose.

By the way, if the disposable diaper is not attached so as to fit the wearer's body, excrement may leak. For example, in a pants-type disposable diaper, the front body and the back body are connected, and the waist circumference of the wearer is configured and positioned continuously in a circumferential shape, so that the positioning is relatively easily performed. . However, the tape-type disposable diaper has a front body and a back body that are detachably fixed by a locking member, so that one of the front body or the back body is biased toward the abdomen or the back, and is drawn out more than the other. A disposable diaper was sometimes worn in a misaligned state. At this time, the absorbent or the disposable diaper may not fit the wearer, and the excrement may leak. In addition, even if the front body and the back body of the tape-type disposable diaper are aligned, the position of the crotch is displaced, so that the absorbent body and the disposable diaper do not fit the wearer, resulting in leakage of excrement. There was something. As described above, it is necessary to position the disposable diaper at an appropriate position while preventing displacement at the time of attachment, and it has been required to attach the disposable diaper so as to fit the wearer's body. In particular, in a disposable diaper in which the front body and the back body have the same design and are difficult to distinguish between the front and the back, the above-described displacement at the time of wearing and the leakage of excrement are likely to occur.

In the disposable diaper 300, a pair of second identification portions 280 are provided at the central portion in the longitudinal direction in the crotch portion 203 of the back sheet 232. Thus, when the disposable diaper 300 is mounted, the center position in the longitudinal direction of the disposable diaper 300 can be confirmed by the second identification unit 280. In addition, by attaching the disposable diaper 300 so as to bend in the longitudinal direction around the second identifying portion 280 while the second identifying portion 280 is at the lowermost position, the disposable diaper 300 is bent from the center position in the longitudinal direction. The lengths to both ends are substantially equal. As described above, by using the second identification unit 280, the crotch part 203 is prevented from being attached to the abdominal side or the back side so as to be deviated to one side, and the disposable diaper 300 is positioned at an appropriate position. Can be. In addition, since the second identification section 280 is provided at a position symmetrical in the width direction, the paper diaper 300 can be positioned at an appropriate position so as to be balanced in the width direction.

Further, the end portions 291A, 291B, 292A, and 292B along the width direction in the design portions 291 and 292 provided on the front body 202 and the back body 204 can also be used for positioning the disposable diaper 300. Contributes to mounting.
Therefore, the positioning of the disposable diaper 300 is facilitated, and the disposable diaper 300 that can be worn so as to fit the wearer's body can be provided.

The design portions 291 and 292 have the same or substantially the same longitudinal dimension, so that the longitudinal position of the disposable diaper 300 can be easily adjusted.
The above design portion 291 and 292, the longitudinal ends of the disposable diaper 300 232B, the distal end 291A of the crotch portion 203 side from 232C, the length L _31, L ₃₂ up to 292A are arranged identical or substantially identical to each other . Therefore, by aligning the positions of the end portions 291A and 292A of the design portions 291 and 292 in the disposable diaper 300 in the attached state, the disposable diaper 300 can be easily attached to an appropriate position.

Further, the design unit 291 and 292 includes a longitudinal direction from the ventral edge portion 232B to end 291B opposite to the crotch portion 203 of the front design portion 291 length L ₂₁ of the diapers 300, longitudinal dorsal are arranged identical or substantially identical to each other opposite the end to 292B length L ₂₂ and the crotch portion 203 of the rear design portion 292 from the end portion 232C. Therefore, by aligning the positions of the ends 291B and 292B of the design portions 291 and 292 in the disposable diaper 300 in the attached state, the disposable diaper 300 can be easily attached to an appropriate position.
In summary, the positioning of the disposable diaper 300 described above can be performed at the crotch portion 203 by the second identification portion 280, and can be performed at the crotch portion 203 side of the design portions 291 and 292 by the end portions 291A and 292A. Thus, the end portions 291B and 292B can be aligned at the longitudinal ends 232B and 232C of the design portions 291 and 292.

Furthermore, the end portions 291A, 292A on the crotch portion 203 side are substantially parallel to the longitudinal end portions 232B, 232C of the disposable diaper 300. Here, when the disposable diaper 300 is mounted, as shown in FIG. 10, the right widthwise end of the design portion 291 in FIG. 7 and the right widthwise end of the design portion 292 in FIG. The left end in the width direction of the design unit 291 in FIG. 7 and the left end in the width direction of the design unit 292 in FIG. In this state, by mounting the paper diaper 300 such that the heights of the end portions 291A and 292A of the design portions 291 and 292 are substantially the same, the heights of both ends in the longitudinal direction of the paper diaper 300 become substantially equal. As described above, by using the design portions 291 and 292, the front body 202 and the back body 204 are prevented from being displaced so as to be biased toward one of the ventral side and the back side, and the disposable diaper 300 is appropriately positioned. Positioning can be performed.

Therefore, according to the disposable diaper 300, by using the second identification unit 280 and the design units 291 and 292, the positioning when attaching the disposable diaper 300 is facilitated, and the disposable diaper 300 is worn so as to fit the wearer's body. be able to. Further, the disposable diaper 300 is difficult to distinguish between the front and rear by the design units 291 and 292, but the positioning is easy. At this time, for example, in a state where the wearer is lying on his / her back, or lying down or lying on his stomach, if the positions of both the design portions 291 and 292 cannot be confirmed, the disposable diaper 300 is confirmed from the crotch portion 203 side. Positioning can be performed using the second identification unit 280. Also, for example, in a state where the wearer is lying sideways and lying down, if the positions of both the second identification unit 280 and the design units 291 and 292 can be confirmed, the front body 202 side and the back body 204 side and the crotch 203 By confirming the disposable diaper 300 from the side, the positioning can be performed using the second identification unit 280 and the design units 291 and 292. When both positions of the design portions 291 and 292 can be confirmed while the wearer is standing, the disposable diaper 300 is confirmed from the front body 202 side and the back body 204 side, so that the design portions 291 and 292 can be confirmed. Can be used for alignment. At this time, by checking the paper diaper 300 from the side as needed, the positioning can be performed using the second identification unit 280. As described above, according to the disposable diaper 300, the front body 202, the crotch 203, and the back body 204 are formed using one of the second identification unit 280 and the design units 291 and 292 according to the posture of the wearer. Positioning can be performed. In addition, by using both the second identification unit 280 and the design units 291 and 292, the positioning of the front body 202, the crotch 203, and the back body 204 can be performed more reliably. Therefore, the disposable diaper 300 can be worn so as to fit the wearer's body, and it is easy to prevent excrement from leaking.

By combining the design portions 291 and 292 having the same or similar appearance with each other, the disposable diaper 300 in which the crotch 203 is disposed at an appropriate position can be attached to the wearer. The bias toward the abdomen or back can be suppressed.

In the disposable diaper 300, the cover sheet 235 is disposed on the non-skin-facing side of the back sheet 232, so that the cover sheet 235 covers the second identification unit 280 and the design units 291 and 292. Accordingly, it is possible to prevent the second identification unit 280 and the design units 291 and 292 from being in contact with other members, rubbing, or the like, and from being stained or thinned. In addition, even when the texture and feel of the back sheet 232 are changed by the second identification unit 280 and the design units 291 and 292 provided on the back sheet 232, the wearer and the user can use the skin of the back sheet 232. The user directly touches the cover sheet 235 located on the non-opposing surface side. For this reason, the influence of providing the second identification unit 280 and the design units 291 and 292 can be suppressed.

The second identification unit 280 has a color different from that of the back sheet 232. This makes it possible to intuitively recognize the position only by looking at the second identification unit 280, and easily distinguish it from the back sheet 232. Therefore, the positioning becomes easier, and it is easier to prevent the excrement from leaking.

The second identification unit 280 and the design units 291 and 292 are provided so as to be visible from the non-skin-facing surface side. Thereby, the front and back of the disposable diaper 300 can be distinguished by the presence or absence of the second identification unit 280 and the design units 291 and 292. In addition, when the disposable diaper 300 is mounted, the positions of the second identification unit 280 and the design units 291 and 292 can be confirmed from the outside. Therefore, the alignment is further facilitated, and it is easy to prevent excrement from leaking.

The second identification unit 280 is provided on the side edge 232 </ b> A of the back sheet 232. Thus, when the disposable diaper 300 is mounted, the position of the second identification unit 280 can be confirmed from the side surface. Therefore, the positioning is further facilitated, and it is easy to prevent the excrement from leaking.

In addition, since the second identification unit 280 is disposed outside the virtual lines VL5 and VL6 in the width direction, the folded state of the disposable diaper 300 can be viewed from the skin-facing surface side to visually recognize the second identification unit 280. Can be. Therefore, it is possible to adjust the position while viewing the folded paper diaper 300 from the skin facing surface side.
