(1) Outline of Embodiment At least the following matters will be apparent from the description of the present specification and the accompanying drawings.

The absorbent article according to one aspect includes a front-rear direction, a width direction perpendicular to the front-rear direction, a thickness direction perpendicular to the front-rear direction and the width direction, an absorbent core including an absorbent material, and A top sheet having an absorption region that is arranged on the skin surface side and overlaps the absorption core in the thickness direction, and an inspection member for inspecting a health condition of a wearer. The inspection member has a contact portion for contacting the excrement of the wearer and a display portion for displaying a health condition of the wearer. The display unit includes an indicator that changes color based on a detection target included in the excrement contacted with the contact unit. At least a part of the contact portion is arranged in a range where the excrement excreted in the absorption region reaches. At least a part of the display unit does not overlap with the absorbing core in the thickness direction.

According to this aspect, since at least a part of the contact portion is arranged in a range where the excrement reaches, the excrement can be brought into contact with the contact portion. Thereby, the indicator contained in the display unit can be colored, and the display unit can display the health condition. In addition, since at least part of the display unit does not overlap with the absorbent core, the wearer can easily view the display unit without blocking at least part of the display unit with the absorbent core. Furthermore, since most excrement is absorbed by the absorbent core, at least a part of the display does not overlap with the absorbent core, so that at least a part of the display does not easily come into contact with excrement. This makes it difficult for at least a part of the display unit to be covered with the excrement, and makes it easier for the wearer to visually recognize the display unit without being affected by the excrement. As described above, since the wearer can easily visually recognize the display unit, it is easy for the wearer to grasp the correct health condition.

According to a preferred embodiment, at least a part of the contact portion contacts the absorbent core. Since the excrement is excreted in the absorbent core, more excretion can be brought into contact with the contact portion by contacting at least a part of the contact portion with the absorbent core. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved.

According to a preferred embodiment, at least a part of the contact portion overlaps the absorbent core in the thickness direction. Since the excrement is excreted in the absorbent core, at least a part of the contact portion overlaps with the absorbent core, so that more excrement can be brought into contact with the contact portion. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved.

According to a preferred embodiment, the absorbent article has a guiding portion for guiding the excrement to at least a part of the contact portion. Since the excrement is guided to at least a part of the contact portion by the guide portion, more excrement can be brought into contact with the contact portion. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved.

According to a preferred aspect, the absorbent article has a main body having the absorbent core and a non-skin surface of the wearing article that extends from the main body to the outside in the width direction and is attached to the wearing article. And a pair of wings fixed to the side. At least a part of the display unit is disposed on one of the pair of wings in the thickness direction. Since the wing is fixed to the non-skin side of the wearing article when attached to the wearing article (for example, underwear), the excrement excreted from the skin side hardly adheres to the wing. This makes it difficult for at least a part of the display unit to be covered with the excrement, and makes it easier for the wearer to visually recognize the display unit without being affected by the excrement. In addition, since the wing is fixed to the non-skin side of the wearing article, when the wearer wears the absorbent article, at least a part of the display section and the wearer's skin are in the thickness direction. There is a wearing article. For this reason, at the time of wearing the absorbent article, it is difficult for at least a part of the display unit to touch the wearer's skin. Even if the indicator contained in the display unit can damage the skin, the safety of the wearer can be improved.

According to a preferred aspect, in the plan view in the thickness direction, at least a portion of the display unit extends from an outer edge of the absorbent core in the front-rear direction. The excrement is more likely to be excreted toward the center than the end in the front-rear direction of the absorbent article, so that it is difficult for the excrement to spread beyond the outer edge of the absorbent core in the front-rear direction. At least a portion of the display unit extends from the outer edge of the absorbent core in the front-rear direction, so that the display unit is not easily covered with excrement, and the wearer can easily view the display unit without being affected by the excrement. .

According to a preferred embodiment, the absorbent article has an absorbent article main body composed of members other than the inspection member. In a plan view in the thickness direction, at least a part of the display unit extends from an outer edge of the absorbent article main body. Since at least a part of the display unit extends from the outer edge of the absorbent article main body, at least a part of the display unit is arranged at a position where excrement cannot be diffused. Thereby, it can suppress that at least one copy of a display part is covered with excrement. In addition, since at least a part of the display unit extends from the outer edge of the absorbent article main body, the wearer can directly visually recognize the display unit. Therefore, it is possible for the wearer to easily grasp the correct health condition.

According to a preferred embodiment, the absorbent article has a plurality of inspection members whose detection targets are different from each other. The display units of each of the plurality of inspection members are arranged at different positions in the thickness direction. Since the detection target is provided with a plurality of inspection members different from each other, a plurality of items indicating the health condition can be confirmed with one absorbent article. Since the display units included in each of the plurality of inspection members are arranged at positions different from each other in the thickness direction, the wearer can easily recognize each of the display units, and it is possible to suppress oversight of some of the display units.

According to a preferred embodiment, the inspection member is arranged on a non-skin side than the top sheet. Since the inspection member is arranged on the non-skin side than the top sheet, it is possible to suppress the inspection member from directly touching the wearer's skin. Thereby, the discomfort at the time of wearing due to the inspection member directly hitting the skin of the wearer can be suppressed. Furthermore, even if the indicator can give irritation to the skin, it becomes difficult for the indicator to touch the skin of the wearer, and the safety of the wearer can be enhanced.

According to a preferred embodiment, the contact portion is arranged on a non-skin side with respect to the absorbent core. The absorption core has an opening penetrating the absorption core in the thickness direction. The contact portion does not overlap with the opening in the thickness direction. The excrement is more likely to reach the non-skin side of the absorbent core where the contact portion is arranged by passing through the opening than through the gap between the fibers constituting the absorbent member of the absorbent core. Therefore, the time required to reach the contact portion can be reduced, and a large amount of excrement can reach the contact portion. Thereby, the inspection accuracy can be improved. Further, when the contact portion contains the indicator, the indicator may be dissolved in the excrement reaching the contact portion. However, since the contact portion does not overlap the opening in the thickness direction, it is difficult for the excrement to reach the non-skin surface side of the absorbent core through the opening. For this reason, even if the indicator can stimulate the skin, it is difficult for the excrement containing the indicator to reach the non-skin side of the top sheet, and the safety of the wearer can be improved.

The absorbent article according to one aspect has a front-rear direction, a width direction perpendicular to the front-rear direction, a thickness direction perpendicular to the front-rear direction and the width direction, and a horizontal direction parallel to the front-rear direction and the width direction. A direction, an absorbent core containing an absorbent material, a backsheet arranged on a non-skin side than the absorbent core, and an inspection member for inspecting a health condition of a wearer. The inspection member is arranged on the skin surface side of the back sheet in the thickness direction. The inspection member has a display unit including an indicator that changes color based on a detection target included in the excrement. The display unit is visible from the back sheet side. A hydrophobic portion having hydrophobicity is arranged in an extension region extending from the display portion in the thickness direction and the horizontal direction on the skin surface side of the back sheet.

Here, Japanese Patent Application Publication No. 2002-538890 discloses an absorbent article provided with an inspection member for inspecting a wearer's health condition. The inspection member has a display unit that displays the health condition of the wearer. The display unit includes a color indicator based on a detection target contained in the excrement. After the excrement of the difference in wearing reaches the inspection member, if the excrement includes the detection target, the color of the display unit changes due to the color reaction of the indicator.

The inspection member is placed in contact with the inner surface of the liquid impermeable film. In the film, the display portion can be visually recognized from a transparent area forming a viewing window. The wearer can confirm the health condition by visually recognizing the display unit.

However, in the absorbent article disclosed in JP-T-2002-538890, the excrement of the wearer reaches at least one of the inspection members when the excrement of the wearer reaches the inspection member. And may overlap. When the display unit is hidden by the excrement covering the inspection member, the wearer cannot visually recognize the display unit and cannot check the health condition. Further, even if the wearer can visually recognize the display unit via the excrement that overlaps the display unit, there is a possibility that the color of the display unit is erroneously recognized based on the color of the excrement. Thus, there is a possibility that the wearer may not be able to grasp the exact health condition based on the excrement.

In the above-described absorbent article according to the present aspect, when the hydrophobic part is disposed in the extension area extending in the thickness direction from the display part, the excrement excreted on the skin side of the absorbent article has a thickness. The hydrophobic part exists on the diffusion path that diffuses toward the display part in the direction. Since the hydrophobic part has hydrophobicity, it is easy to suppress the water-soluble excrement from diffusing to the display part side. Further, when the hydrophobic portion is disposed in an extension region extending in the horizontal direction from the display portion, on the diffusion path in which the excrement diffused inside the absorbent article is diffused in the horizontal direction toward the display portion, There is a hydrophobic part. The hydrophobic part can easily prevent the water-soluble excrement from diffusing to the display part side. Further, even when the display unit is not arranged in a range where the excrement reaches while the absorbent article is worn, the excrement may reach the display unit due to unexpected movement of the wearer. is there. Even in such a case, it is easy to suppress the excrement from reaching the display unit by the hydrophobic part arranged in the extension area. As described above, it is easy to suppress the excrement from covering or overlapping the display unit, and it is easy to ensure the visibility of the display unit. Accordingly, when the wearer visually recognizes the display unit from the back seat side, the wearer can easily grasp the correct health condition.

According to a preferred embodiment, the absorbent article has a top sheet that is arranged on the skin surface side of the absorbent core and has an absorbent region overlapping the absorbent core in the thickness direction. The hydrophobic part disposed in the extension region is disposed in a range where the excrement discharged in the absorption region reaches. This can prevent the excrement reaching the hydrophobic part from being diffused to the display part side, so that the visibility of the display part can be easily secured. Accordingly, when the wearer visually recognizes the display unit from the back seat side, the wearer can easily grasp the correct health condition.

According to a preferred embodiment, the hydrophobic part is in contact with the display part. Thereby, it is possible to suppress the excrement from reaching the display unit. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

According to a preferred embodiment, the hydrophobic portion is in contact with a surface on the non-skin side of the display unit. Thereby, it is possible to suppress the excrement from reaching the surface of the display section visually recognized from the back sheet side. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

According to a preferred aspect, the inspection member is arranged between the absorbent core and the back sheet in the thickness direction. In the thickness direction, a sheet-like sheet member is arranged as the hydrophobic portion between the absorbing core and the display unit. Since the sheet member is disposed between the absorbent core and the display unit, it is possible to suppress the excrement diffused from the skin surface side to the non-skin surface side from reaching the display unit. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

According to a preferred embodiment, the absorbent article 1 has an excretion port contact portion that contacts the excretion port of the wearer. In a plan view in the thickness direction, the hydrophobic portion is closer to the center of the excretion opening contact portion than the display portion. Since the hydrophobic part is closer to the center of the excretion port contact part than the display part, the hydrophobic part exists on the diffusion path in which the excrement excreted in the excretion port contact part diffuses toward the display part. The hydrophobic part can suppress the excrement diffused from the excretion opening contact part toward the display part from reaching the display part. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

According to a preferred embodiment, the absorbent article 1 has a skin-side member disposed closer to the skin than the display unit. The skin surface side member is a region that does not overlap with the display unit in the thickness direction, and has a background region that is visible from the back sheet side. The color of the display unit is a color having a hue difference of 120 degrees or more in a hue circle with respect to the color of the background area. Thus, the display portion is visually recognized by being emphasized by the color of the background region. This makes it easier for the wearer to visually recognize the display unit, so that the wearer can easily grasp the correct health condition.

According to a preferred embodiment, the color of the display unit is a color having a hue difference of 120 degrees or more in terms of a hue circle with respect to the color of the excrement. Thereby, the display portion is visually recognized with the display portion highlighted by the color of the excrement. This makes it easier for the wearer to visually recognize the display unit, so that the wearer can easily grasp the correct health condition.

According to a preferred embodiment, the absorbent article 1 has a skin-side member disposed closer to the skin than the display unit. The skin surface side member is a region that does not overlap with the display unit in the thickness direction, and has a background region that is visible from the back sheet side. The color of the background area is a color having a hue difference of 45 degrees or less in the hue circle with respect to the color of the excrement. Even if the excrement permeates the skin-side member, the color of the background area is a color whose hue difference is not more than 45 degrees in the hue circle angle with respect to the color of the excrement, so that the excrement is inconspicuous. This makes it easier for the wearer to visually recognize the display unit without being distracted by the color of the excrement, thereby making it easier to grasp an accurate health condition.

The absorbent article 1 has a central area S3, a front area S1 and a rear area S2. The central area S3 is an area having an excretion port contact portion that contacts an excretion port (for example, a vaginal opening) of the wearer. When the absorbent article is worn on the wearing article (for example, underwear), the central region S3 is located at the crotch of the wearing article. That is, the central region is a region located between the wearer's crotch, that is, between the wearer's feet. In the embodiment in FIG. 1, the central region S3 is a region where the wings 14 for fastening the absorbent article 1 to the wearing article are provided. The front side area S1 is located on the front side of the central area S3. The rear area S2 is located behind the central area S3.

As shown in FIGS. 1 and 2, the absorbent article 1 may include an absorbent article main body 10 formed of members other than the inspection member 60, and the inspection member 60. The absorbent article main body 10 may correspond to a general absorbent article such as a sanitary napkin that does not include the inspection member 60. That is, the absorbent article main body 10 may correspond to the absorbent article 1 having no inspection member 60.

The absorbent article main body 10 may be constituted by the main body 12 and a pair of wings 14. The main body 12 has an absorbent core 20. The main body portion 12 is a portion inside the wing 14 in the width direction W. The pair of wings 14 extend from the main body 12 to the outside in the width direction W, and are fixed to the non-skin side T2 of the wearing article when attached to the wearing article. The boundary between the main body 12 and the wing 14 is a fold FL extending in the front-rear direction L.

The absorbent article 1 includes the absorbent core 20, the top sheet 30, and the inspection member 60. Further, the absorbent article 1 may include a back sheet 40, a side sheet 50, and an adhesive section 70.

The absorbent core 20 includes an absorbent material that absorbs liquid. Absorbent materials can be formed, for example, from hydrophilic fibers, pulp and superabsorbent polymers (SAP). The absorbent core 20 may be wrapped by a core wrap (not shown). The core wrap only needs to cover the absorbent core 20 at least on the skin-facing surface side of the absorbent core 20. As a specific example, the core wrap may include a sheet disposed on the skin side of the absorbent core 20 and a sheet disposed on the non-skin side of the absorbent core 20.

The side sheet 50 may cover the outer edge of the top sheet 30. The side sheet 50 may cover the outer edge of the top sheet 30 in the width direction W, and may extend outside the top sheet 30 in the width direction W. Note that the absorbent article 1 may not have the side sheet 50.

The side sheet 50 can be made of the same material as the top sheet 30. However, in order to prevent the bodily fluid attached to the top sheet 30 from crossing the side sheet 50 and leaking out of the absorbent article 1 in the width direction W, the side sheet 50 has hydrophobicity or water repellency. May have. The side sheet 50 may be disposed on the outer edge of the absorbent core 20 in the width direction W, the wing 14 described later, and the flap portion 80 described later.

The inspection member 60 is a member for inspecting a wearer's health condition. The inspection member 60 displays the health condition (color indicating) of the wearer with an indicator. In the present embodiment, for examining a health condition, for example, an immunochromatography method or a test paper method can be used.

The immunochromatography method is performed by dropping excrement (eg, blood) on a member (eg, a cellulose membrane) on which labeled particles containing antibodies are spread. When the excrement contains a detection target (specifically, a target component (eg, an antigen) to be detected), the detection target and the antibody cause an antigen-antibody reaction to form a complex. . The formed complex moves on the membrane by capillary action. A different type of antibody (indicator) is linearly arranged at the destination of the complex. The complex is colored by binding to another type of antibody. The presence or absence of coloration (color change) indicates the health condition of the wearer. The wearer can confirm the health condition by visually determining the presence or absence of coloration.

In the test paper method, the indicator is included in the inspection member 60 and color is generated when the indicator reacts with the detection target included in the excrement. The presence or absence of coloration (change in the color of the indicator) indicates the health condition of the wearer. The wearer can visually confirm the coloration (change in the color of the indicator) by the indicator to confirm the health condition.

Excretions include, for example, blood, urine, stool, sweat, vaginal discharge, and the like. Items indicating health status include, for example, physical condition-related (pH, iron deficiency anemia, renal function, myocardial infarction, inflammation / infection, nutritional status evaluation, etc.), pregnancy-related (physiological cycle prediction, ovulation prediction, etc.), mental-related (Depression, drugs, etc.). The detection target is, for example, urine waste (urine specific gravity), leukocyte, hydrogen ion (pH), protein, glucose, ketone body, urobilinogen, bilirubin, urinary occult blood, nitrite, steroid, peptide, aromatic compound, FSH ( Follicle stimulating hormone), BUN (Urea @ nitorogen), AlB (Albumin), LPS (lipopolysaccharide), hCG (human chorionic gonadotropin), LH (luteinizing hormone), U-ALB, CRP (C-reactiv protein), Examples include myoglobin, CK-MB, troponin I, troponin T, hemoglobin, strep A, HBs antibody, HIV antibody, TP antibody, rotavirus, influenza virus, adenovirus, DNA, O-157, cocaine, marijuana, morphine and the like. No.

The inspection member 60 has a contact part 62 and a display part 64. The contact part 62 is a part for making excretion contact. The display unit 64 is a part that displays the health state (color indicating) of the wearer. The display unit 64 includes an indicator that changes color based on the detection target contained in the excrement that has come into contact with the contact unit 62. The indicator is a chemical substance (inorganic substance, organic substance) that is colored by reacting with a detection target or a substance derived from the detection target (for example, a complex).

For example, in the immunochromatography, the contact portion 62 is a portion for guiding excrement (test target) to a region where the labeled particles including the antibody are arranged. The contact portion 62 may include a region where the label particles are arranged. When the excrement touches the contact portion 62, the detection target (antigen) and the antibody contained in the excretion cause an antigen-antibody reaction to form a complex. The display unit 64 includes a region (detection line) in which an indicator (another type of antibody) that is colored by binding to the complex is arranged. Therefore, when the immunochromatography method is used, the contact section 62 and the display section 64 are arranged at different positions. Therefore, in this case, the contact section 62 and the display section 64 are different.

Note that the test member 60 may include a control line that is a color region regardless of the presence or absence of the target antigen to be detected when the test is appropriate. The control line is located farther from the contact section 62 than the detection line (display section 64).

On the other hand, in the test paper method, the contact portion 62 includes at least a region where the indicator is arranged. Since the indicator contained in the contact part 62 reacts with the detection target to give a color, the contact part 62 and the display part 64 are arranged at the same position. Therefore, in this case, the contact portion 62 and the display portion 64 are the same.

As described above, when the immunochromatography method is used, the contact portion 62 includes a label particle, and the display portion 64 includes an indicator for displaying a wearer's health condition. When the test strip method is used, the contact part 62, that is, the display part 64, includes an indicator for displaying the health condition of the wearer.

In the case where the contact portion 62 is provided only for guiding the excrement (a detection target) to the display portion 64, the contact portion 62 may not include the indicator.

The inspection member 60 may be any member that can hold or contain the indicator. The inspection member 60 can be made of any material such as paper, nonwoven fabric, and woven fabric. The rigidity of the inspection member 60 may be equal to or less than the rigidity of the member used for the absorbent article 1. Thereby, even if the absorbent article 1 is provided with the inspection member 60, it becomes easy to suppress deterioration of the touch of the wearer. As shown in FIG. 1 and the like, the inspection member 60 may be, for example, a linear plate shape.

ＡAs shown in FIG. 2A, at least a part of the contact portion 62 is arranged in a reach range where the excrement excreted in the absorption area AR reaches. Thereby, the excrement excreted from the wearer can be brought into contact with the contact portion 62. Therefore, the indicator contained in the display unit 64 can be colored, and the display unit 64 can display the health condition.

少なくとも At least a part of the contact portion 62 may be in contact with the absorbent core. Since the excrement is excreted in the absorbent core 20, more excretion can be brought into contact with the contact portion 62. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved. In FIG. 2A, a part of the contact portion 62 is in contact with the absorbent core 20.

少なくとも At least a part of the contact portion 62 may overlap the absorbent core 20 in the thickness direction T. Since the excrement is excreted in the absorbent core 20, more excretion can be brought into contact with the contact portion. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved. In FIG. 2A, a part of the contact portion 62 overlaps the absorbent core 20 in the thickness direction T. The rest of the contact portion 62 does not overlap with the absorbent core 20 in the thickness direction.

The reaching range may be a diffusion range of the excrement when the excrement is a liquid. The reach may be a range where the excrement spreads during wear when the excrement is solid / semi-solid. In a horizontal direction that is a direction along the front-rear direction L and the width direction W (that is, a plan view in the thickness direction T), in a general use, the maximum range of the reaching range is excreted in the absorption region AR. This is an area that overlaps with at least one of the liquid-permeable sheets that directly or indirectly comes into contact with the top sheet 30 through which excrement that can be diffused. Note that a liquid-permeable sheet that comes into “indirect” contact with the top sheet 30 means that it is in contact with the top sheet 30 via another liquid-permeable sheet. The excrement excreted in the top sheet 30 can be diffused to the liquid permeable sheet via another liquid permeable sheet. On the other hand, in the thickness direction T (that is, in the cross section of the absorbent article 1), the maximum range of the reaching range is a range from the surface of the top sheet 30 on the skin side T1 to the surface of the back sheet 40 on the skin side T1. It is.

少なくとも At least a part of the contact portion 62 only needs to be arranged within the maximum range of the reaching range. At least a part of the contact portion 62 is disposed at a position overlapping the top sheet 30 in the thickness direction T or at a position overlapping the absorbent core 20 so that the excrement easily reaches the contact portion 62. , May be arranged in the central area S3, or may be arranged in the range of the excretion opening contact portion that contacts the excretion opening of the wearer. Thereby, the excrement excreted from the wearer can be brought into contact with the contact portion 62. Therefore, the indicator contained in the display unit 64 can be colored, and the display unit 64 can display the health condition.

少なくとも At least a part of the display unit 64 does not overlap with the absorbing core 20 in the thickness direction T. This makes it easier for the wearer to visually recognize the display unit 64 without blocking at least a part of the display unit 64 with the absorbent core 20. Furthermore, since most of the excrement is absorbed by the absorbent core 20, at least a part of the display unit 64 does not overlap with the absorbent core 20, so that at least a part of the display unit 64 does not easily come into contact with the excrement. This makes it difficult for at least a part of the display unit 64 to be covered with excrement, and makes it easier for the wearer to visually recognize the display unit 64 without being affected by the excrement. As described above, since the wearer can easily visually recognize the display unit 64, the wearer can easily grasp the correct health condition. In FIG. 2A, not all of the display portions 64 overlap the absorbing core 20 in the thickness direction T.

In the case where the absorbent member 1 includes the inspection member 60 using the test paper method, a part of the region of the inspection member 60 containing the indicator is disposed in the reach. The display portion 64, which is the remaining region including the indicator, does not overlap with the absorbent core 20 in the thickness direction T. The excrement penetrates from the area arranged in the reaching range, and the display unit 64 can display color. In addition, since the area | region arrange | positioned in the reaching range is the display part 64 at the same time as the contact part 62, it can color. Therefore, in this case, a part of the display unit 64 overlaps the absorbing core 20 in the thickness direction.

On the other hand, when the absorbent member 1 includes the test member 60 using the immunochromatography method, a portion (at least the contact portion 62) that guides the excrement (test target) to the region where the labeled particles including the antibody are arranged. Are located in reach. The detection line (display portion 64), which is the region where another type of antibody (indicator) that is colored by binding to the complex derived from the detection target, does not overlap with the absorption core 20 in the thickness direction T.

検査 As shown in FIG. 2A, the inspection member 60 may be inserted into the exposure opening 52 formed in the side sheet 50. Thereby, at least a part of the display unit 64 may be exposed. Specifically, the display unit 64 may include a non-exposed portion 642 located on the non-skin side T2 than the side sheet 50 and an exposed portion 644 located on the skin side T1 than the side sheet 50. The non-exposed portion 642 may be indirectly visible through the side sheet 50. The exposed part 644 is directly visible.

In the inspection member 60 using the immunochromatography method, the exposed part 644 may have a detection line that is at least a part of the display part 64. This allows the wearer to directly check the display section 64, and thus can easily check the health condition. Further, the exposure section 644 may have a control line without including the detection line. Thereby, the wearer can easily confirm that the inspection has been properly performed by visually recognizing the exposed portion 644.

In the case where the top sheet 30 is arranged on the wing 14, the "side sheet 50" may be replaced with the "top sheet 30".

少なくとも At least a part of the display unit 64 may be arranged on one of the pair of wings 14 in the thickness direction T. As shown in FIG. 2B, the wings 14 are fixed to the non-skin side T2 of the wearing article 100 in a state where the wings 14 are attached to the wearing article 100 (for example, underwear), so that excrement excreted from the skin side T1. Hardly adhere to the wing 14. This makes it difficult for at least a part of the display unit 64 to be covered with excrement, and makes it easier for the wearer to visually recognize the display unit 64 without being affected by the excrement.

In addition, since the wing 14 is fixed to the non-skin side T2 of the wearing article 100, when the wearer wears the absorbent article 1, at least a part of the display unit 64 and the wearer's in the thickness direction T. Wearing article 100 exists between the skin. For this reason, at the time of wearing the absorbent article 1, at least a part of the display unit 64 becomes difficult to touch the skin of the wearer. Even if the indicator contained in the display unit 64 can damage the skin, the safety of the wearer can be improved.

The inspection member 60 may be fixed (joined) to at least one of the absorbent core 20, the top sheet 30, the back sheet 40, and the side sheet 50. The inspection member 60 may be fixed by, for example, an adhesive (for example, a hot melt adhesive (HMA)) for joining the materials of the absorbent article 1 together. In the inspection member 60, at least one of the contact portion 62 and the display portion 64 may be fixed. In the inspection member 60, at least a part of the contact part 62 may be fixed, and at least a part of the display part 64 may be fixed. The inspection member 60 may have a portion other than the contact portion 62 and the display portion 64 fixed. For example, the inspection member 60 may have a fixed part configured by at least a part of the part other than the contact part 62 and the display part 64. It may be fixed by an adhesive applied on the fixing part. By fixing the inspection member 60, it is possible to prevent the contact portion 62 from moving outside the reach.

The adhesive portion 70 is a region provided with an adhesive for fixing the absorbent article 1 to the wearing article 100. The adhesive section 70 is disposed on the non-skin side T2 of the back sheet 40 and is for fixing the absorbent article 1 to a worn article (for example, underwear) 100.

The adhesive portion 70 may have a central adhesive portion 72 and a side adhesive portion 74. As shown in FIG. 2A, the central adhesive portion 72 is disposed on the non-skin side T2 of the back sheet 40 in the main body 12. The central adhesive portion 72 has an adhesive for fixing the main body 12 to the wearing article 100. The side adhesive portion 74 is arranged on the non-skin side T2 of the back sheet 40 on the wing 14. The side adhesive portion 74 has an adhesive for fixing the wing 14 to the wearing article 100.

As shown in FIGS. 3A and 3B, the wearer may be able to visually recognize the display unit 64 with the wearing article 100 put on his / her leg by removing the wing 14 from the wearing article 100. Thereby, the wearer can easily check the health condition.

(4) The adhesive strength of the side adhesive portion 74 may be smaller than the adhesive strength of the adhesive for fixing the inspection member 60. Thereby, the wearer may remove the back sheet 40 from the wearing article 100 by holding the exposed portion 644 of the display unit 64 and pulling the exposed portion 644 as shown in FIG. 3A. The wearer can easily remove the wing 14 from the wearing article 100.

(4) The adhesive strength of the side adhesive portion 74 may be larger than the adhesive strength of the adhesive for fixing the side sheet 50. Accordingly, even if the wearer grasps the exposed portion 644 of the display unit 64 and pulls the exposed portion 644 as shown in FIG. 3B, the top sheet 30 and the inspection member 60 can be removed from the back sheet 40. Good. This allows the wearer to directly check not only the exposed portion 644 but also the non-exposed portion 642, so that the wearer can easily check the health condition.

FIG. 7D is a plan view of the absorbent article 1 in a modification (10) according to the first embodiment as viewed from the skin surface side. FIG. 8 is a diagram for describing each modification example according to the first embodiment. Specifically, FIG. 8A is a plan view of the absorbent article 1 in a modification (No. 11) according to the embodiment as viewed from the skin surface side. FIG. 8B is a plan view of the absorbent article 1 as viewed from the skin surface side in a modification (twelfth) according to the first embodiment. The description of the same parts as those in the first embodiment will be omitted.

ＡAs shown in FIG. 4A, the contact portion 62 may be arranged on the skin surface side T1 with respect to the absorbent core 20. Therefore, the contact portion 62 may contact the surface of the absorbent core 20 on the skin side T1. The contact portion 62 may be disposed between the absorbent core 20 and the topsheet 30. Thereby, the excrement easily comes into contact with the contact portion 62 without being blocked by the absorbent core 20.

接触 As shown in FIG. 4B, the contact portions 62 may be arranged between the absorbent cores 20 in the thickness direction T. The contact portion 62 may be arranged between the absorbent cores 20 by being inserted from the side surface of the absorbent core 20 in the width direction W. The absorbent core 20 may be provided with an opening on a side surface of the absorbent core 20 for inserting the contact portion 62 (the inspection member 60). Alternatively, the contact portion 62 may be disposed between the absorbent cores 20 by being sandwiched between two absorbent cores 20 stacked in the thickness direction T. The excrement absorbed by the absorbent core 20 diffuses in the absorbent core 20, so that the excrement easily comes into contact with the contact portion 62.

接触 As shown in FIG. 4C, the contact portion 62 may contact the side surface of the absorbent core 20. The contact portion 62 may be in contact with the excrement diffused to the side surface of the absorbent core 20 in the width direction W. Thereby, the excrement easily comes into contact with the contact portion 62 easily. In addition, as shown in FIG. 4C, the contact portion 62 may not overlap the absorbent core 20 in the thickness direction T as long as the contact portion 62 is arranged in the range of the excrement.

ＡAs shown in FIG. 5A, the absorbent article 1 may have a guiding portion 22 for guiding excrement to at least a part of the contact portion 62. The guide portion 22 may be an area that is easier to draw in liquid (excretion) than its surroundings. Since the excrement is guided to at least a part of the contact portion 62 by the guide portion 22, more excrement can be brought into contact with the contact portion 62. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved.

Specifically, the absorbent core 20 may have a low-weight portion 221 as the guide portion 22. The basis weight of the absorbent material in the low basis weight portion 221 is lower than the basis weight of the surrounding absorbent material. Therefore, excrement is more easily diffused in the low weight portion 221 than in the surrounding area. The low weight portion 221 may extend from the skin surface of the absorbent core 20 to the non-skin surface side in the thickness direction. The basis weight of the low basis weight portion 221 may be a value larger than 0. Alternatively, the basis weight of the low basis weight portion 221 may be zero. That is, the low-weight portion 221 may be an opening penetrating the absorbent core 20 in the thickness direction T. The absorbent core 20 may have an opening penetrating the absorbent core 20 in the thickness direction.

As shown in FIG. 5A, at least a part of the contact portion 62 arranged on the non-skin side T2 with respect to the absorbent core 20 may overlap the low-weight portion 221 (for example, an opening) in the thickness direction T. . This makes it easier for the excrement to reach the contact portion 62 through the opening. The indicator can be colored based on many detection targets, and the inspection accuracy can be improved.

5B, as shown in FIG. 5B, the contact portion 62 disposed on the non-skin side T2 with respect to the absorbent core 20 does not have to overlap the low-weight portion 221 (for example, an opening) in the thickness direction T. Therefore, in a plan view in the thickness direction T, the contact portion 62 may be arranged at a position away from the opening. The excrement is more likely to reach the non-skin side T2 of the absorbent core 20 where the contact portion 62 is arranged by passing through the opening than through the gap of the fiber constituting the absorbent member of the absorbent core 20. . The excrement reaching the non-skin side T2 can reach the contact portion 62 by diffusion. Therefore, the time required to reach the contact portion 62 can be reduced, and a large amount of excrement can reach the contact portion 62. Thereby, the inspection accuracy can be improved. When the contact portion 62 contains the indicator, the indicator may be dissolved in the excrement that has reached the contact portion 62. However, since the contact portion 62 does not overlap the opening in the thickness direction T, it is difficult for excrement to reach the non-skin side T2 of the absorbent core 20 through the opening. For this reason, even if the indicator can stimulate the skin, it is difficult for excrement containing the indicator to reach the non-skin side T2 of the top sheet 30, and the safety of the wearer can be enhanced.

As shown in FIG. 6A and FIG. 6B, the top sheet 30 has a plurality of protrusions 32 arranged in parallel, which are formed by being bent to have a wavy cross section, and a plurality of protrusions 32 adjacent to each other. And a bottom portion (s) 34 disposed therebetween. The bottom portion 34 may extend from a region overlapping the absorbent core 20 in the thickness direction T to a region overlapping the contact portion 62 in the thickness direction T. The excrement E excreted in the absorption area AR flows down to the bottom 34 even when excreted in the projection 32. Therefore, the excrement E is easily collected on the bottom 34 and reaches the position overlapping the contact portion 62 in the thickness direction T using the bottom 34 as a path. As described above, even when the contact portion 62 is not in contact with the absorbent core 20, the excrement E is guided to the contact portion 62 by the bottom portion 34 as the guide portion 22, so that at least the contact portion 62 A part may be arranged in the reach of the excrement E. Therefore, as shown in FIG. 6B, the contact portion 62 may be arranged away from the absorbent core 20.

As shown in FIG. 7A, in a plan view in the thickness direction T, at least a part of the display unit 64 may extend from the outer edge of the absorbent core 20 in the front-rear direction L. Therefore, at least a part of the display unit 64 may be disposed on the flap unit 80. The flap 80 is a portion from the outer edge of the absorbent core 20 to the outer edge of the absorbent article 1. The flap 80 may include a front flap 81 that is a flap in the front area S1 and a rear flap 82 that is a flap in the rear area S2.

(4) Since excrement is more easily excreted toward the center than the end in the front-rear direction L of the absorbent article 1, it is difficult to diffuse beyond the outer edge of the absorbent core 20 in the front-rear direction L. Since at least a part of the display unit 64 extends from the outer edge of the absorbent core 20 in the front-rear direction L, it is difficult for the display unit 64 to be covered with the excrement, and the wearer can operate the display unit 64 without being affected by the excrement. It becomes easy to see.

As shown in FIG. 7A, at least a part of the display unit 64 may extend from the outer edge of the absorbent core 20 in the front-rear direction L in the front side area S1. Therefore, at least a part of the display unit 64 may be disposed on the front flap unit 81. In a state where the absorbent article 1 is lowered to a position near the knee, the front flap portion 81 is at a position where it is easy to visually recognize. Therefore, the wearer can easily visually recognize the display section 64 without completely removing the absorbent article 1 from the body.

In addition, since urine easily reaches the front side area S1 as compared with the rear side area S2, as shown in FIG. 7A, at least the front side area S1 includes the inspection member 60 that detects a target component contained in urine. And at least a part of the contact portion 62 can be arranged in the front side area S1. Thereby, more excrement can be brought into contact with the contact portion 62. The indicator can be colored based on many detection targets, and the inspection accuracy can be improved.

As shown in FIG. 7B, since the stool easily reaches the rear area S2 as compared with the front area S1, as shown in FIG. 7B, the inspection member 60 which detects the target component contained in the stool is a target. Can be arranged at least in the rear area S2, and at least a part of the contact portion 62 can be arranged in the rear area S2. Thereby, more excrement can be brought into contact with the contact portion 62. The indicator can be colored based on many detection targets, and the inspection accuracy can be improved.

7A and 7B, the inspection member 60 may be arranged on the non-skin side T2 with respect to the top sheet 30. It is possible to prevent the inspection member 60 from directly touching the wearer's skin. Thereby, the discomfort at the time of wearing due to the inspection member 60 directly hitting the skin of the wearer can be suppressed. Furthermore, even if the indicator can give irritation to the skin, it becomes difficult for the indicator to touch the skin of the wearer, and the safety of the wearer can be enhanced.

In addition, the top sheet 30 may have transparency. Thereby, the wearer may be able to visually recognize the coloration of the inspection member 60 via the top sheet 30. Further, as described above, the wearer may be able to visually recognize the coloration of the inspection member 60 by peeling the top sheet 30 (and / or the side sheet 50) from the back sheet 40.

透明 The transparency of the topsheet 30 can be specified by the opacity (OP). If the topsheet 30 has 0% opacity, it is completely transparent. On the other hand, when the topsheet 30 has 100% opacity, it does not have transparency, that is, the topsheet 30 does not transmit light. Therefore, the opacity of the topsheet 30 is less than 100%. The opacity of the top sheet 30 may be 50% or less so that the color of the display unit 64 can be visually recognized more accurately. The opacity of the top sheet 30 may be 8.5% or less in order to more accurately recognize the color of the display unit 64.

In order to determine the opacity, a dispersion colorimeter may be used. For example, a dispersion colorimeter is available from BYK-Gardner GmbH (Geretsried, Germany) under the trade name “BYK-Gardner Color-Guide 45/0” (Geretsried). Catalog No. 6800). The measurement can be performed at a viewing angle of 2 ° (degrees) using the light source “A”. The dispersion colorimeter comprises a light source for illuminant A (ie, something similar to an incandescent lamp having a correlated color temperature of about 3000 K), a flat table, a white standard plate, a standard black plate, a multi-cell light. A photodetector comprising a detector diode array; and a computer. White and black standard plates are available from the company under catalog numbers 6811 and 6810, respectively.

際 When measuring, place the white standard plate on a flat table. The sample material is placed flat on a white standard plate. The sample material is irradiated with a light source having an incident angle of 45 °. Light reflected from the sample material is received by a photodetector at a light receiving angle of 0 °. The reflectance (Yw) of the reflected light is detected by a photodetector. Similarly, after placing the black standard plate on a flat table, the sample material is placed flat on the black standard plate. The sample material is irradiated with a light source having an incident angle of 45 °. Light reflected from the sample material is received by a photodetector at a light receiving angle of 0 °. The reflectance (Yb) of the reflected light is detected by a photodetector.

Opacity (OP) can be obtained by the following equation.

OP (%) = (Yb / Yw) × 100
This process is repeated at least five times for one sample sheet material, and the average value of the measured opacity (OP) is calculated and recorded with a colorimeter. The average value of the measured opacity is called the opacity of the sheet material.

Note that the topsheet 30 is a heat source that compresses the topsheet 30 in the thickness direction T while heating over a predetermined region of a part of the surface of a nonwoven fabric (for example, SMS (spunbond / meltblown / spunbond)). A compression process may be performed. Thereby, a high-density part may be formed in the top sheet 30. The compression process for forming the high-density portion is performed by subjecting the top sheet 30 (nonwoven fabric) to a known pressure process such as a calendering process or an embossing process. In the high-density portion, the fibers on the surface of the nonwoven fabric are compacted, whereby fine irregularities on the surface are reduced and the surface is in a smooth state as compared with a region where the high-density portion is not formed. By such a heat compression process, the top sheet 30 may have transparency.

Although the top sheet 30 has been described as an example, when the display unit 64 overlaps the side sheet 50 in the thickness direction T, the side sheet 50 has transparency similarly to the top sheet 30. Good.

ＣAs shown in FIG. 7C, in a plan view in the thickness direction T, at least a part of the display unit 64 may extend from the outer edge 10 e of the absorbent article main body 10. In this case, a portion extending from the outer edge 10e of the absorbent article main body 10 corresponds to the exposed portion 644. Since at least a part of the display unit 64 extends from the outer edge 10e of the absorbent article main body 10, at least a part of the display unit 64 is arranged at a position where excrement cannot be diffused. Accordingly, it is possible to prevent at least a part of the display unit 64 from being covered with excrement. In addition, since at least a part of the display unit 64 extends from the outer edge 10e of the absorbent article main body 10, the wearer can directly view the display unit 64. Therefore, it is possible for the wearer to easily grasp the correct health condition.

As shown in FIG. 7C, in the front side area S <b> 1, at least a part of the display unit 64 may extend from the outer edge 10 e of the absorbent article main body 10. In a state where the absorbent article 1 is lowered to near the knee, the wearer can visually recognize the display portion 64 (the exposed portion 644). The wearer can easily confirm the presence or absence of coloration. In addition, since at least a part of the display unit 64 is not arranged in the absorbent article main body 10, it is difficult to contact the excrement. This makes it difficult for at least a part of the display unit to be covered with the excrement, and makes it easier for the wearer to visually recognize the display unit without being affected by the excrement.

ＤAs shown in FIG. 7D, in the central area S3, at least a part of the display section 64 may extend from the outer edge 10e of the absorbent article main body 10. At least a portion of the display 64 may extend from an outer edge of the wing 14. Since the wings 14 are fixed to the non-skin side T2 of the wearing article 100, the excrement excreted from the skin side hardly adheres to the wings 14. This makes it difficult for at least a part of the display unit 64 to be covered with the excrement, and makes it easier for the wearer to visually recognize the display unit without being affected by the excrement. Furthermore, since the wing 14 is fixed to the non-skin surface side T2 of the wearing article 100, even if the exposed portion 644 exists, the exposed portion 644 is less likely to touch the wearer's skin. Even if the indicator contained in the exposed portion 644 can damage the skin, the safety of the wearer can be improved.

In addition, at least a part of the display part 64 may extend from the outer edge 10e of the absorbent article main body 10 in the rear area S2 as well as in the front area S1 or the central area S3.

ＡAs shown in FIG. 8A, the absorbent article 1 may have a plurality of inspection members 60 whose detection targets are different from each other. The display units 64 included in each of the plurality of inspection members 60 may be arranged at different positions in the thickness direction T. Since a plurality of inspection members 60 whose detection targets are different from each other are provided, a plurality of items indicating a health condition can be confirmed with one absorbent article 1. Since the display portions 64 included in each of the plurality of inspection members 60 are arranged at positions different from each other in the thickness direction T, the wearer can easily recognize each of the display portions 64 and overlook some of the display portions 64. Can be suppressed.

For example, the plurality of inspection members 60 may include a first inspection member 60A and a second inspection member 60B. The display part 64A of the first inspection member 60A may be arranged on one wing 14A, and the display part 64B of the second inspection member 60B may be arranged on the other wing 14B.

表示 As shown in FIG. 8B, the display section 64A of the first inspection member 60A may be disposed in the front side area S1. Therefore, at least a part of the display unit 64 </ b> A may be disposed on the front flap unit 81. Further, the display section 64B of the second inspection member 60B may be arranged in the rear area S2. Therefore, at least a part of the display unit 64 </ b> B may be disposed on the rear flap unit 82. The first inspection member 60A may be the inspection member 60 that detects a target component contained in urine as a detection target. The second inspection member 60B may be the inspection member 60 that detects a target component contained in the stool. In this way, even if a plurality of health conditions are displayed by arranging the detection member including the indicator that changes color based on the detection target in an area where the excrement including the detection target is easily excreted, Therefore, the wearer can easily grasp the health condition.

(4) Second Embodiment Next, an absorbent article 1 according to a second embodiment will be described. The description of the same parts as in the above-described embodiment will be omitted.

FIG. 9 is a plan view of the absorbent article according to the second embodiment as viewed from the skin side. FIG. 10 is a plan view of the absorbent article according to the second embodiment as viewed from the non-skin side. FIG. 11 is a cross-sectional view of the absorbent article according to the second embodiment. Specifically, FIG. 11 is a cross-sectional view along the line AA shown in FIG.

The absorbent article 1 includes the absorbent core 20, the back sheet 40, and the inspection member 60. Further, the absorbent article 1 may include the top sheet 30, the side sheet 50, and the adhesive section 70.

The back sheet 40 is arranged on the non-skin side with respect to the absorbent core 20. The back sheet 40 may have liquid impermeability. The back sheet 40 has transparency. Thereby, as shown in FIG. 11, even if the inspection member 60 is arranged on the skin surface side T1 with respect to the back sheet 40 in the thickness direction T, as shown in FIG. It is possible.

In the present invention, the term “visible” refers to a distance of about 30 to 50 cm in a room (approximately: 500 to 750 lx (lux)) brightly illuminated with a neutral white color (color temperature reference: 4600 to 5400 K (Kelvin)). This means that a subject having good visual acuity (1.0 or more) with both eyes can visually recognize the subject when viewing it.

透明 The transparency of the back sheet 40 can be specified by the opacity (OP). The backsheet 40 is completely transparent if it has 0% opacity. On the other hand, when the back sheet 40 has 100% opacity, it does not have transparency, that is, the back sheet 40 does not transmit light. Therefore, the opacity of the back sheet 40 is less than 100%. The opacity of the back sheet 40 may be 50% or less so that the inspection member 60 (the display unit 64) can be visually recognized more accurately. The opacity of the back sheet 40 may be 8.5% or less in order to more accurately view the color of the display unit 64.

The backsheet 40 is subjected to a heat compression process of compressing the backsheet 40 in the thickness direction T while heating over the entire area of the surface of the nonwoven fabric (for example, SMS (spunbond / meltblown / spunbond)). May be. Thereby, a high-density portion may be formed on the back sheet 40. The heat compression process for forming the high-density portion is performed by subjecting the back sheet 40 (nonwoven fabric) to a known pressure process such as a calendering process or an embossing process. In the high-density portion, the fibers on the surface of the nonwoven fabric are compacted, whereby fine irregularities on the surface are reduced and the surface is in a smooth state as compared with a region where the high-density portion is not formed. By the heat compression process, the back sheet 40 may have transparency. In addition, by using the backsheet 40 made of the nonwoven fabric that has been subjected to the treatment, a zipper sound is less likely to be generated when the absorbent article 1 is opened, and it is difficult for others to notice when using the absorbent article 1.

The adhesive section 70 may have transparency. In FIG. 10, the central adhesive portion 72 overlaps (a part of) the display portion 64 in the thickness direction T. For this reason, the central adhesive portion 72 may have transparency. The adhesive section 70 may have transparency by being made of, for example, HMA.

吸収 As shown in FIGS. 9 to 11, the absorbent article 1 has a hydrophobic portion 90 having hydrophobicity. The hydrophobic portion 90 is disposed in an extension region ER extending in the thickness direction T and the horizontal direction from the display portion 64 on the skin surface side with respect to the back sheet 40.

When the hydrophobic portion 90 is disposed in the extension region ER extending from the display portion 64 in the thickness direction T, the excrement excreted on the skin surface side T1 of the absorbent article 1 is displayed in the thickness direction T on the display portion. The hydrophobic portion 90 exists on a diffusion path that diffuses toward 64. Since the hydrophobic part 90 has hydrophobicity, it is easy to suppress the water-soluble excrement from diffusing to the display part 64 side. When the hydrophobic part 90 is arranged in the extension region ER extending in the horizontal direction from the display part 64, the excrement diffused inside the absorbent article 1 is diffused in the horizontal direction toward the display part 64. The hydrophobic part 90 exists on the diffusion path. The hydrophobic part 90 can easily suppress the water-soluble excrement from diffusing to the display part 64 side. As described above, it is easy to suppress the excrement from covering the display unit 64 or overlapping the display unit 64, and it is easy to ensure the visibility of the display unit 64. Accordingly, when the wearer visually recognizes the display unit 64 from the back sheet 40 side, the wearer can easily grasp the correct health condition.

疎水 As in the present embodiment, the hydrophobic portion 90 arranged in the extension region ER may be arranged in the reach of the excretion excreted in the absorption region AR. This can suppress the excrement reaching the hydrophobic part 90 from being diffused to the display part 64 side, so that the visibility of the display part 64 can be easily secured. Thereby, when the wearer visually recognizes the display unit 64 from the back seat side, it becomes easier for the wearer to grasp an accurate health condition.

疎水 As shown in FIG. 11, the hydrophobic part 90 may be in contact with the display part 64. It is possible to suppress the excrement from reaching the display unit 64. Thereby, the visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

The hydrophobic portion 90 disposed in the extension region ER includes a skin-side hydrophobic portion 92 disposed on the skin surface side T1 with respect to the display portion 64 and a non-skinned portion disposed on the non-skin surface side T2 with respect to the display portion 64. It may include a skin-side hydrophobic portion 94 and a side-surface-side hydrophobic portion 96 disposed outside the display portion 64 in the horizontal direction (the width direction W in FIG. 11).

The skin-side hydrophobic portion 92 that is the hydrophobic portion 90 may be in contact with the skin-side surface of the display unit 64. Thereby, it is possible to suppress the excrement that diffuses from the skin surface side T1 to the non-skin surface side T2 from reaching the display unit 64. The visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

非 The non-skin side hydrophobic portion 94 which is the hydrophobic portion 90 may be in contact with the skin side surface of the display portion 64. Thereby, it is possible to suppress the excrement from reaching the surface of the display section 64 visually recognized from the back sheet side. The visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

(4) The side surface side hydrophobic portion 96 which is the hydrophobic portion 90 may be in contact with the side surface of the display portion 64. Thereby, it is possible to suppress the excrement diffused in the horizontal direction from reaching the display unit 64. The visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

疎水 As shown in FIG. 11, the hydrophobic portion 90 may cover the periphery of the display portion 64. Therefore, the hydrophobic portion 90 may be arranged in a region different from the extension region ER. The hydrophobic part 90 may cover the entire surface of the display part 64. The hydrophobic part 90 may cover a part of the display part 64. The hydrophobic part 90 may cover a part of the contact part 62. The hydrophobic part 90 does not cover the entire surface of the contact part 62 so that the excrement reaches the contact part 62.

The hydrophobic portion 90 can be constituted by a layer or a member having hydrophobicity. For example, a water-repellent layer as the hydrophobic portion 90 may be provided by performing a water-repellent process of attaching (applying) a water-repellent agent to a part of the contact portion 62 by a water-repellent spray, a coating device, or the like. The member constituting the display unit 64 may be impregnated with a water repellent. A portion to which the water repellent is not to be attached (for example, (a part of) the contact portion 62) may be covered with a masking tape or the like. After covering the contact portion 62 with the hydrophobic portion 90, the contact portion 62 may be exposed by peeling off a masking tape or the like. The water repellent may be a silicone water repellent or a fluorine water repellent. It is preferable that the water repellent (hydrophobic portion 90) does not easily discolor.

The hydrophobic portion 90 may be made of the same material as the back sheet 40. The hydrophobic part 90 may be formed of a bonding layer (for example, a hot melt adhesive (HMA)) for bonding the members constituting the absorbent article 1. Thereby, the inspection member 60 can be fixed and the hydrophobic portion 90 can be formed.

The hydrophobic portion 90 may have transparency. For example, the non-skin side hydrophobic portion 94 may have transparency in order to make the coloration easily visible. On the other hand, since the skin-side hydrophobic portion 92 is disposed closer to the skin surface T1 than the display portion 64, the skin-side hydrophobic portion 92 does not need to have transparency, and may have transparency. Further, the side surface side hydrophobic portion 96 does not need to have transparency, and may have transparency.

It is sectional drawing of the absorbent article 1 for describing the example (the 4). FIG. 13 is a diagram for describing each modification example (No. 5 to No. 6) according to the second embodiment. Specifically, FIG. 13A is a plan view of the absorbent article 1 for explaining a fifth modification of the second embodiment as viewed from the non-skin side, and FIG. 13B is a second embodiment. It is the top view which looked at the absorbent article 1 for demonstrating the example of a change (the 6) from the non-skin side. FIG. 14 is a diagram for describing each modification example (No. 7 to No. 8) according to the second embodiment. Specifically, FIG. 14A is a plan view of the absorbent article 1 for explaining a modification (No. 7) of the second embodiment when viewed from the non-skin side, and FIG. 14B is a second embodiment. It is the top view which looked at the absorptive article 1 for explaining the modification (the 8) of (a) from the non-skin side. FIG. 15 is a cross-sectional view of the absorbent article 1 for describing a modified example (No. 9) according to the second embodiment. The description of the same parts as those in the first and second embodiments will be omitted.

ＡAs shown in FIG. 12A, the hydrophobic portion 90 may be arranged so as to contact the surface of the display surface 64 on the skin surface side T1, and may not be arranged on the non-skin surface side T2 than the display portion 64. The hydrophobic portion 90 does not need to be arranged so as to be in contact with the horizontal outer surface of the display portion 64.

疎水 As shown in FIG. 12B, the hydrophobic portion 90 may be arranged so as to contact the surface of the non-skin surface side T2 of the display portion 64, and need not be arranged on the skin surface side T1 than the display portion 64. The hydrophobic portion 90 does not need to be arranged so as to be in contact with the horizontal outer surface of the display portion 64.

検査 As shown in FIG. 12C, the inspection member 60 may be arranged between the absorbent core 20 and the back sheet 40. In the absorbent article 1, a sheet-shaped sheet member may be disposed as the hydrophobic portion 90 between the absorbent core 20 and the display portion 64. Since the sheet member is disposed between the absorbent core 20 and the display unit 64, it is possible to suppress the excrement diffused from the skin side T1 to the non-skin side T2 from reaching the display unit 64. Thereby, the visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

疎水 As shown in FIG. 12D, the hydrophobic portion 90 may be a core wrap 25 wrapping the absorbent core 20. The core wrap 25 may have a hydrophilic part 222 and a hydrophobic part 90 having hydrophilicity. The hydrophilic part 222 may be located on the skin surface side T1 with respect to the hydrophobic part 90. The hydrophobic portion 90 located on the non-skin side T2 with respect to the absorbent core 20 may overlap with a part of the absorbent core 20 in a plan view in the thickness direction T. A portion that does not overlap with the absorbent core 20 in the thickness direction T may be a hydrophilic portion. When the hydrophobic portion 90 located on the non-skin side T2 with respect to the absorbent core 20 overlaps with the entire region of the absorbent core 20 in a plan view in the thickness direction T, the hydrophobic portion 90 causes excrement to reach the contact portion 62. To reach, an aperture may be formed.

ＡAs shown in FIG. 13A, the absorbent article 1 may have an excretion port contact portion 35 that contacts the excretion port of the wearer. The top sheet 30 may have the excretion opening contact part 35. In a plan view in the thickness direction T, the hydrophobic portion 90 may be closer to the center 35 </ b> C of the excretion opening contact portion 35 than the display portion 64. Since the hydrophobic portion 90 is closer to the center 35C of the excretion port contact portion 35 than the display portion 64, the excrement discharged to the excretion port contact portion 35 is spread on the diffusion path for diffusing toward the display portion 64. There is a section 90. The hydrophobic part 90 can suppress the excrement diffused from the excretion opening contact part 35 toward the display part 64 from reaching the display part 64. Thereby, the visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

The hydrophobic portion 90 may be disposed so as to contact the inner surface of the display portion 64 in the front-rear direction L, and may not be disposed outside the display portion 64 in the front-rear direction L.

疎水 As shown in FIG. 13B, the hydrophobic part 90 may be arranged so as not to contact the display part 64. By disposing the hydrophobic part 90 apart from the display part 64, it is possible to suppress the excrement from being diffused to the vicinity of the display part 64. This makes it difficult for the excrement to reach the vicinity of the display section 64, and the wearer can be less likely to be confused by the color of the excrement.

ＡAs shown in FIGS. 14A and 14B, the absorbent article 1 may include a skin-side member disposed on the skin-side T1 with respect to the display unit 64. The skin-side member may have a background region BR that is a region that does not overlap with the display unit 64 in the thickness direction T and that is visible from the back sheet 40 side. In FIG. 14A, the skin-side member is the absorbent core 20, and in FIG. 14B, the skin-side member is the topsheet 30. The color of the display unit 64 may be a color having a hue difference of 120 degrees or more in hue circle angle with respect to the color of the background region BR. Thereby, the display unit 64 is visually recognized by being emphasized by the color of the background region BR. Therefore, the wearer can easily visually recognize the display unit 64, and thus can easily grasp an accurate health condition.

The color of the display unit 64 may be a color having a hue difference of 165 degrees or more in the hue circle with respect to the color of the background region BR so that the display unit 64 can be visually emphasized. The color of the display section 64 may be a color having a hue difference of 180 degrees in the hue circle with respect to the color of the background area BR, that is, a color complementary to the background area BR.

The color of the display section 64 may be a color having a hue difference of 120 degrees or more in the hue circle with respect to the color of the excrement. Thus, the display section is highlighted and visually recognized by the color of the excrement. This makes it easier for the wearer to visually recognize the display unit, so that the wearer can easily grasp the correct health condition. The color of the display portion 64 may be a color having a hue difference of 165 degrees or more in the hue circle angle with respect to the color of the excrement, and may be 180 degrees so that the display portion 64 can be visually emphasized. Good.

The color of the display unit 64 may be a color before the indicator is colored. Thus, the wearer can easily visually recognize the display unit 64 when the indicator is not colored. The display unit 64 may be at least a part of the color after the indicator is colored. Thereby, the wearer can easily visually recognize (at least a part of) the display unit 64 when the indicator is colored.

In addition, when the color of the display unit 64 and the color around the display unit 64 are not the same and similar colors (for example, the hue difference is a color of 45 degrees or more in the angle of the hue circle), at least one of the inspection members The color around the display unit 64 may be a color having a hue difference of 45 degrees or less as an angle of a hue circle with respect to the color of the background region BR. Thereby, the color of the display unit 64 can be easily visually recognized, and the display unit 64 can be easily visually recognized. The color of the inspection member 60 itself except for the display unit 64 may be a color having a hue difference of 45 degrees or less in hue circle angle with respect to the color of the background region BR.

The color of the background area BR may be a color having a hue difference of 45 degrees or less in terms of the hue circle with respect to the color of the excrement. Even if the excrement permeates the skin-side member, the color of the background area is a color having a hue difference of 3 or less with respect to the color of the excrement, so that the excrement is inconspicuous. This makes it easier for the wearer to visually recognize the display section 64 without being confused by the color of the excrement, and thus to easily grasp the correct health condition. In order to make the display unit 64 more easily recognizable, the color of the background area BR may be a color having a hue difference of 1 or less with respect to the color of the excrement, and the color of the background area BR is the same color as the excrement. It may be. In order to make the excrement less noticeable, the color of the background area BR may be a color having a hue difference of 30 degrees or less and a color of 15 degrees or less with respect to the color of the excrement in a hue circle angle. May be. The color of the background area BR may be the same color as the color of the excrement (that is, 0 degrees in the hue circle).

(4) At least the color of the display member 64 around the inspection member may be a color having a hue difference of 120 degrees or more in hue circle angle with respect to the color of the background region BR. Accordingly, the color around the display unit 64 can be easily visually recognized, and the display unit 64 can be easily visually recognized. At least the color around the display unit 64 of the inspection member may be a color having a hue difference of 165 degrees or more in the hue circle angle with respect to the color of the background area BR, and may be 180 degrees. In addition, the color of the inspection member 60 itself may be a color having a hue difference of 120 degrees or more, a color of 165 degrees or more, or 180 degrees with respect to the color of the background area BR in a hue circle angle. May be.

(4) The color of at least the periphery of the display unit 64 in the inspection member may be a color having a hue difference of 120 degrees or more in the hue circle with respect to the color of the excrement. Thereby, even if excrement permeates into the skin side member, the color around the display section 64 can be easily visually recognized, and the display section 64 can be easily visually recognized. The color of at least the periphery of the display unit 64 in the inspection member may be a color having a hue difference of 165 degrees or more in the hue circle with respect to the color of the background region BR, and may be 180 degrees. In addition, the color of the inspection member 60 itself may be a color having a hue difference of 120 degrees or more, a color of 165 degrees or more, or 180 degrees with respect to the color of the excrement in a hue circle angle. Good.

The color around the display unit 64 (or the color of the inspection member 60 itself other than the display unit 64) is white, the color of the display unit 64 (the color before or after the coloration) is red, and the background The color of the region BR may be black. Since white has a high lightness and black has a low lightness, the white surrounding the display unit 64 is better illuminated against the black background, and the red color of the display unit 64 can be clearly recognized. As described above, in order to make the lightness difference more conspicuous, for example, the lightness difference between the part to be visually recognized (the display unit 64, the periphery of the display unit 64, etc.) and the other region (the background region BR, excrement, etc.) It may be 125 or more. The lightness (difference) can be calculated using “((R value X 299) + (G value X 587) + (B value X 114)) / 1000”. The hue difference can be measured by a general measuring method. For example, a hue difference can be measured by using a hue circle such as “Munsell hue circle” or “PCCS hue circle”. For example, in the PCCS hue circle, a color having a hue of 8 or more with the color of the display unit 64 has an angle of 120 degrees or more from the color of the display unit 64. A color having a hue difference of 11 or more from the color of the display unit 64 has an angle of 165 degrees or more from the color of the display unit 64, and a color having a hue difference of 12 from the color of the display unit 64 is a color of the display unit 64. The angle from the color is 180 degrees (that is, the complementary color).

As shown in FIG. 15, at least a part of the display unit 64 may be arranged on one of the pair of wings 14 in the thickness direction T. Since the wing 14 is fixed to the non-skin side T2 of the wearing article 100 in a state where the wing 14 is attached to the wearing article 100 (for example, underwear), excrement excreted from the skin side T1 adheres to the wing 14. hard. This makes it difficult for at least a part of the display unit 64 to be covered with excrement, and makes it easier for the wearer to visually recognize the display unit 64 without being affected by the excrement.

において In FIG. 15, the hydrophobic portion 90 is arranged on the surface of the display portion 64 on the skin surface side T1. Since at least a part of the display unit 64 is disposed on the wing 14, the display unit 64 and the hydrophobic unit 90 need not be disposed in the reach. In addition, even when the display unit 64 and the hydrophobic unit 90 are not arranged in a range where the excrement reaches in general use, the excrement is displayed on the display unit 64 due to unexpected movement of the wearer. May be reached. Even in such a case, it is easy to suppress the excrement from reaching the display part 64 by the hydrophobic part 90 arranged in the extension area.

(6) Other Embodiments As described above, the present invention has been described in detail with reference to the above embodiments. However, for those skilled in the art, the present invention is not limited to the embodiments described in this specification. Is clear. The present invention can be implemented as modified and changed aspects without departing from the spirit and scope of the present invention defined by the description of the claims. Therefore, the description in this specification is for the purpose of illustrative explanation, and has no restrictive meaning to the present invention.

In the first embodiment described above, the back sheet 40 may have transparency. The back sheet 40 may have the same transparency as the above-described top sheet 30. Thereby, the wearer may be able to visually recognize the coloration of the inspection member 60 from the back sheet 40 side via the back sheet 40.

表示 In the above-described first embodiment, the display unit 64 is exposed and the contact unit 62 is not exposed. However, the present invention is not limited to this. The contact portion 62 may be exposed. When the contact part 62 and the display part 64 are different (for example, the inspection member 60 using the immunochromatography method), at least a part of the contact part 62 is arranged on the skin side T1 with respect to the top sheet 30 in the absorption region AR. You may. In the inspection member 60 using the immunochromatography method, the contact portion 62 does not contain the indicator. For this reason, even if the contact portion 62 touches the skin of the wearer, there is no possibility of damaging the skin of the wearer. Furthermore, since the excrement E can be brought into direct contact with the contact portion 62, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved. Further, at least a part of the display unit 64 may be disposed on the non-skin side T2 with respect to the top sheet 30 (and / or the side sheet 50). Thereby, since the indicator contained in the display unit 64 can be prevented from directly touching the skin, the safety of the wearer can be improved.

On the other hand, when the contact portion 62 and the display portion 64 are the same (for example, the inspection member 60 using the test paper method), as described above, the inspection member 60 is closer to the non-skin side T2 than the top sheet 30. May be arranged. This makes it difficult for the indicator to touch the wearer's skin, even if the indicator can stimulate the skin, thereby improving the safety of the wearer.

In the above-described second embodiment, an example in which the entire surface of the back sheet 40 is transparent has been described, but the present invention is not limited to this. In the back sheet 40, in the thickness direction T, a region overlapping with the display unit 64 may have transparency. Other parts of the back sheet 40 may not have transparency. By performing the above-described embossing process on a part of the nonwoven fabric as the backsheet 40, only a part of the backsheet 40 may have transparency. Thereby, the user (wearer) can be given a sense of security by the soft touch unique to the nonwoven fabric.

In the above description, the hydrophobic portion 90 is in contact with the surface of the display portion 64 in the thickness direction T, but is not limited to this. For example, the hydrophobic part 90 may be arranged at a position separated from the display part 64 in the thickness direction T.

In the above description, the absorbent article 1 may have a guiding portion that makes it easy to draw in the excrement in order to make it difficult for the excrement to reach the display section 64. When the guiding unit draws in the excrement, it is difficult for the excrement to reach the display unit 64. The guide portion may be arranged near the contact portion 62 or may be arranged to contact the contact portion 62.

In the above-described first and second embodiments, the inspection member 60 has a linear plate shape. In the present embodiment, the inspection member 60 may have, for example, one or more folds. Therefore, the inspection member 60 may have, for example, a two-fold or three-fold shape. The inspection member 60 may be configured by a member folded into a Z shape. Thereby, the inspection member 60 can be arranged inside the absorbent article 1 in a compact state. Since the area of the inspection member 60 is reduced, deterioration of the touch of the wearer by the inspection member 60 can be easily suppressed.

In addition, the inspection member 60 is folded so that at least a part of the contact portion 62 contacts another member other than the inspection member 60 (that is, at least a part of the contact portion 62 faces another member). And may be arranged. Thereby, even if the inspection member 60 is folded, the excrement can easily reach the contact portion 62.

The inspection member 60 is folded so that at least a part of the display unit 64 abuts on another member other than the inspection member 60 (that is, at least a part of the display unit 64 faces another member). And may be arranged. Thereby, even if the inspection member 60 is folded, the wearer can easily visually recognize the display unit 64.

Note that the wearer may acquire the test information by sending color information (image information and / or video information) indicating the color of the display unit 64 to a network (management server). For example, the wearer may acquire the color information by photographing the exposed display unit 64 with a camera built in a communication device owned by the wearer (user), for example. The wearer can send the color information to the management server via the communication device. The wearer may send user information indicating the wearer's information together with the coloration information. The user information is, for example, at least one of a user identifier, a communication device identifier, information indicating the type of excrement, information indicating the type of the absorbent article 1 (inspection member 60), information specifying a detection target, and the like. is there.

着用 Moreover, the wearer may house the absorbent article 1 including the inspection member 60 or the inspection member 60 itself in an accommodation device capable of detecting a color reaction by the indicator. The storage device may irradiate the display unit 64 with visible light to detect a color reaction. The storage device irradiates special light having a special wavelength different from visible light (for example, ultraviolet light having a shorter wavelength than visible light) to the inspection member 60 capable of confirming coloration by the indicator, and Light having a wavelength may be applied to the display unit 64. The accommodation device may acquire the color information by photographing while irradiating visible light or special light in the accommodation device. As described above, by photographing the display unit 64 while irradiating light in the housing device, it is possible to accurately confirm the coloration without being affected by the surrounding environment.

The accommodation device may send the color information acquired by photographing the display unit 64 to a network (management server). In this case, the accommodation device may include the identifier of the accommodation device as the user information.
