[0011] (1) Overview of the embodiment [Aspect 1] An absorbent core; a skin-facing sheet disposed closer to the skin than the absorbent core; and a test member disposed on the skin side of the absorbent core for testing the health condition of a user. The test member is an absorbent article having an indicator portion that changes color based on excrement, An absorbent article, wherein the color difference between the skin side sheet and the indicating portion after coloring is 0.6 or more.

[0012] With the above-mentioned absorbent article, the color of the indicator after coloring is unlikely to resemble the color of the skin-side sheet, making it easier to visually recognize the indicator after coloring. The user can easily determine whether the indicator has colored or not without removing the test member from the absorbent article, making it easier to check the user's health condition simply and accurately.

[0013] [Aspect 2] An absorbent core; a skin-facing sheet disposed closer to the skin than the absorbent core; and a test member disposed on the skin side of the absorbent core for testing the health condition of a user. The test member has an indicator portion that changes color based on the body waste.

[0014] The absorbent article allows the user to easily and accurately check the user's health condition.

[0015] [Aspect 3] The skin side sheet has a top sheet that is disposed on the skin side of the test member, the test member has a contact portion with which the excrement comes into contact in order to cause the indication portion to change color, the skin side sheet has a recess that is recessed toward the non-skin side from the surrounding area, The recess overlaps with the contact portion in the thickness direction. 3. The absorbent article according to claim 1 or 2.

[0016] In the recess of the absorbent article, the excrement flows toward the non-skin side from a position closer to the contact part than from the periphery of the recess, so that the excrement can reach the contact part more easily. This makes it easier for the indicator to change color and shortens the time it takes for the indicator to change color, making it easier for the user to check their health condition.

[0017] [Aspect 4] 4. The absorbent article of claim 3, wherein the recess does not overlap with the indicating portion in the thickness direction. In the above-mentioned absorbent article, the recess does not overlap with the display portion in the thickness direction, so that even if the user uses the absorbent article for a long period of time or engages in vigorous movement, the materials and components constituting the display portion are unlikely to come into direct contact with the user's skin, providing a sense of security to the user.

[0018] [Aspect 5] the test member further includes an indicator moving section between the indicator section and the contact section, through which a component contained in the excrement moves from the contact section to the indicator section, The recess does not overlap with the display moving portion in the thickness direction. 5. The absorbent article according to claim 3 or 4.

[0019] In the absorbent article, the inspection member further includes a predetermined indicator moving part, and the recess does not overlap with the indicator moving part in the thickness direction. Therefore, the function of the indicator moving part is unlikely to be hindered by the user's sweat, etc., and even if the user uses the absorbent article for a long time or moves vigorously, the members and components constituting the indicator moving part are unlikely to come into direct contact with the user's skin, so that the user can feel at ease.

[0020] [Aspect 6] The absorbent article has creases formed therein for folding the absorbent article, The fold is formed at a position that does not overlap with the display unit in the thickness direction. The absorbent article according to any one of aspects 1 to 5.

[0021] When the display unit is folded, creases may form in the display unit, reducing the visible area of ​​the display unit, and the display unit may be damaged by the fold, reducing the area of ​​the display unit that shows color. In the absorbent article, the fold is formed at a position that does not overlap with the display portion in the thickness direction, so that the display portion is not folded and a decrease in visibility of the display portion after color development can be suppressed.

[0022] [Aspect 7] The absorbent article has creases formed therein for folding the absorbent article, The inspection member is a contact portion with which the excrement comes into contact in order to cause the display portion to change color; a display transfer section in which components contained in the excrement transfer from the contact section to the display section; having The fold is formed at a position not overlapping with the display moving portion in the thickness direction. The absorbent article according to any one of aspects 1 to 6.

[0023] When the display moving part is bent, the display moving part may be damaged by the folding, which may impede the transport of components contained in the excrement. In this case, the components contained in the excrement that travel to the display part are reduced, making it difficult for the display part to change color. In the above-mentioned absorbent article, the fold is formed at a position that does not overlap with the display moving portion in the thickness direction, so that the portion from the contact portion to the display portion is not folded, and the accuracy of the coloring of the display portion can be maintained.

[0025] When a user places the absorbent article or a wearing article to which the absorbent article is fixed around both legs and moves the absorbent article away from the crotch area, the user can more easily see the portion in front of the center of the front-to-back direction of the absorbent article (hereinafter referred to as the front-to-back center) than the portion behind the center. In the above-mentioned absorbent article, the front-to-back center of the inspection member is located forward of the front-to-back center of the absorbent article, making it easy for the user to know whether or not the display portion has changed color, and making it easy to check the user's health condition.

[0026] [Aspect 9] the test member has a contact portion with which the excrement comes into contact in order to cause the indication portion to change color, The contact portion is located rearward of the center of the absorbent article in the front-rear direction. The absorbent article according to any one of aspects 1 to 8.

[0027] In the above absorbent article, the contact portion is located behind the center of the absorbent article in the front-to-back direction. Therefore, when lying on one's back, the user's excrement (especially bodily fluids) flows backward due to gravity, and the excrement easily reaches the contact portion located behind the center of the absorbent article in the front-to-back direction. This makes it easier for the indicator to change color, making it easier for the user to check their health condition.

[0028] [Aspect 10] 10. The absorbent article according to any one of aspects 1 to 9, wherein a bending guide portion that guides bending of the absorbent article in the width direction is provided outside the inspection member in the width direction.

[0029] Since the absorbent article is held between the legs of the user, when the user narrows the distance between the legs, a force acting inward in the width direction may be applied to the inspection member. When force is applied to the inspection member, the inspection member may be deformed, and the function of the inspection member may be reduced. In the above-mentioned absorbent article, since the bending guide portion is provided on the outer side of the test member in the width direction, the bending guide portion guides the bending of the absorbent article, and the absorbent article is easily bent on the outer side of the test member in the width direction. This makes it difficult for the force toward the inside in the width direction to be transmitted to the test member, and makes it difficult for the function of the test member to deteriorate. Therefore, the accuracy of the coloring of the indicator can be maintained, and the health condition of the user can be accurately confirmed.

[0030] [Aspect 11] 11. The absorbent article according to any one of aspects 6 to 10, wherein the absorbent article is selected from the group consisting of sanitary napkins, panty liners, adult incontinence pads, and urine absorption pads.

A package for absorbent articles.

[0038] In the above package, since the rigidity of the packaging member is greater than that of the inspection member, even if the rigidity of the inspection member is low, the rigidity of the packaging member makes it difficult for the inspection member to bend before the package is opened, thereby preventing the inspection member from being damaged and its function from being reduced before the package is opened.

[0039] [Aspect 17] 17. The absorbent article package according to claim 16, wherein a color difference between the skin side sheet and the indicating portion after coloring is 0.6 or more. With the above-mentioned package, the user can easily ascertain whether or not the indicator has changed color without removing the test member from the absorbent article, making it easier to check the user's health condition simply and accurately.

[0040] [Aspect 18] A package for absorbent articles according to aspect 16 or 17, wherein the absorbent article is the absorbent article according to any one of aspects 1 to 15. In the above package, since the absorbent article is the absorbent article according to any one of the first to fifteenth aspects, the effect of any one of the first to fifteenth aspects can be achieved.

[0041] According to a preferred embodiment, the skin side sheet has a top sheet disposed closer to the skin than the test member, and the top sheet has a visible light transmittance of 60% or more, allowing a user to more clearly see the color of the display unit after coloring through the top sheet, making it easier for the user to know whether the display unit has changed color or not.

[0042] According to a preferred embodiment, the skin side sheet has a top sheet arranged on the skin side of the test member, and the basis weight of the top sheet is 90 gsm or less. This makes it difficult for the top sheet arranged on the skin side of the test member to interfere with the visibility of the color of the indicator after coloring, making it easier to know whether the indicator has changed color or not.

[0043] According to a preferred embodiment, the absorbent article has a non-skin-facing sheet disposed on the non-skin-facing side of the absorbent core, and an adhesive portion provided on the non-skin-facing side of the non-skin-facing sheet to fix the absorbent article to the wearing article, and at least a part of the test member overlaps with the adhesive portion in the thickness direction. The area overlapping with the adhesive portion in the thickness direction is adhered to the wearing article via the adhesive portion. Therefore, the area overlapping with the adhesive portion in the thickness direction is less likely to float from the wearing article and to come into contact with the user's body than the area not overlapping with the adhesive portion in the thickness direction. By overlapping at least a part of the test member with the adhesive portion, it is possible to reduce the separation of the test member from the wearing article. This makes it difficult for the test member to continue to receive force from the user's body, and makes it difficult for the function of the test member to deteriorate. Therefore, it is possible to maintain the accuracy of the coloring of the indicator, and to accurately check the user's health condition.

[0044] According to a preferred embodiment, the absorbent article has a non-skin-facing sheet disposed on the non-skin-facing side of the absorbent core, the non-skin-facing sheet being a liquid-impermeable and breathable sheet. This reduces stuffiness of the absorbent article compared to when the non-skin-facing sheet is a non-breathable film. This reduces false reactions of the test member due to sweat from the user, making it easier for the user to accurately check their health condition.

[0045] According to a preferred embodiment, a display area overlapping the display unit in the thickness direction and a surrounding area surrounding the test member are provided, and when the absorbent article is viewed from the skin side, the maximum color difference between the surrounding area and the display area after the display unit has changed color is 0.6 or more. Since the maximum color difference between the display area after the display unit has changed color and the surrounding area is 0.6 or more, the user can easily visually recognize the display unit after changing color by viewing the absorbent article from the skin side. The user can easily determine whether the display unit has changed color without removing the test member from the absorbent article, and can easily and accurately check the user's health condition.

The thickness direction T is a direction extending from the skin-facing side of the user to the non-skin-facing side (T2), or from the non-skin-facing side of the user to the skin-facing side (T1). The thickness direction T is also a direction perpendicular to the front-rear direction L and the width direction W. The skin-facing side corresponds to the side facing the skin of the user when in use. The non-skin-facing side corresponds to the side opposite to the skin-facing side, i.e., the side facing away from the skin of the user when in use.

[0048] As shown in FIG. 1, the absorbent article 1 may have a front region S1, a rear region S2, and a central region S3. The front region S1 is located in front of the central region S3, and the rear region S2 is located behind the central region S3. The central region S3 includes a region that contacts a user's excretory opening (for example, a vaginal opening). The front region obtained by dividing the absorbent article 1 into three equal parts in the front-to-rear direction L may be the front region S1, the rear region may be the rear region S2, and the central region S3 may be the central region between the front region S1 and the rear region S2. When the absorbent article 1 has wings, the central region S3 may be a region from the front edge of the root of the wings to the rear edge of the root of the wings. The wings are portions that are folded back to the non-skin-facing side of the worn article when the absorbent article 1 is used.

[0049] The absorbent article 1 may include an absorbent core 20, a skin side sheet 30, a non-skin side sheet 40, an adhesive portion 50, and a testing member 60. The absorbent core 20 includes an absorbent material that absorbs liquid. The absorbent material may be composed of, for example, at least one of pulp and a superabsorbent polymer.

[0050] The skin side sheet 30 is disposed on the skin side T1 of the absorbent core 20. The skin side sheet 30 may have a top sheet 31 disposed on the skin side T1 of the test member 60. The top sheet 31 faces the skin of the user. The top sheet 31 may be composed of multiple sheets, for example, a top sheet that faces the skin of the user, and a sheet that is disposed on the non-skin side T2 of the top sheet and on the skin side T1 of the test member 60. In the embodiment, the skin side sheet 30 is composed of the top sheet 31. The top sheet 31 (skin side sheet 30) may be composed of, for example, a spunlace nonwoven fabric, an air-through nonwoven fabric, a spunbond nonwoven fabric, an SMS nonwoven fabric, or the like.

[0051] The visible light transmittance of the top sheet 31 may be 60% or more. The visible light transmittance of the top sheet 31 may be preferably 70% or more, and more preferably 80% or more. The basis weight of the top sheet 31 may be 90 gsm or less, 30 gsm or less, or 17 gsm or less. The thickness of the top sheet 31 may be 5 mm or less.

[0052] The non-skin side sheet 40 is disposed on the non-skin side T2 of the absorbent core 20. The non-skin side sheet 40 may have a back sheet 41 that faces the worn article. The non-skin side sheet 40 may be made of, for example, a liquid-impermeable film.

As shown in Figures 2 and 3, the adhesive portion 50 may be provided in an area overlapping with the absorbent core 20 in the thickness direction T, or may be provided in an area not overlapping with the absorbent core 20 in the thickness direction T. The adhesive portion 50 may be provided on the wing. The absorbent article 1 is fixed to a wearing article via the adhesive portion 50.

[0054] The test member 60 is a member for testing the health condition of the user. The test member 60 displays the health condition of the user by coloring (color change) based on excrement. Examples of excrement (specimens) include blood (menstrual blood), urine, feces, sweat, vaginal discharge, etc. Items indicating the health condition include, for example, physical condition-related (pH, iron deficiency anemia, renal function, myocardial infarction, inflammation / infection, nutritional state evaluation, etc.), pregnancy-related (menstrual cycle prediction, ovulation prediction, etc.), and mental health-related (depression tendency, drugs, etc.). Examples of detection targets include urinary waste products (urine specific gravity), white blood cells, hydrogen ions (pH), protein, glucose, ketone bodies, urobilinogen, bilirubin, urinary occult blood, nitrite, steroids, peptides, aromatic compounds, FSH (follicle-stimulating hormone), BUN (urea nitrogen), AlB (albumin), LPS (lipopolysaccharide), hCG (human chorionic gonadotropin), LH (luteinizing hormone), U-ALB, CRP (C-reactive protein), 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, and morphine. The detection targets are chemical substances (inorganic and organic) determined according to the items that indicate health status, and react with other chemical substances to cause coloration.

[0055] The inspection member 60 has a display unit 62 that changes color based on the excrement. The display unit 62 displays the health condition of the user. The display unit 62 may display the health condition of the user by the color after coloring, or may display the health condition of the user by the presence or absence of coloring. The user can check the health condition by visually determining the color after coloring and / or the presence or absence of coloring. The display unit 62 may include an indicator that changes color based on the excrement.

[0056] The indicator may contain a chemical substance (inorganic or organic) that changes color by reacting with the target of detection contained in the excrement or with a substance derived from the target of detection (for example, a complex formed by an antigen-antibody reaction between the target of detection and an antibody). The indicator may also contain a chemical substance (inorganic or organic) that changes color by reacting with an antibody (a chemical substance that causes an antigen-antibody reaction with the target of detection) that has migrated with the excrement.

[0057] The display unit 62 may be configured with a plurality of display units each having a different detection target. As shown in Fig. 1 and Fig. 3, the display unit 62 may have, for example, a first display unit 62A and a second display unit 62B. The first display unit 62A is located closer to the contact unit 64 than the second display unit 62B. The test member 60 has a contact portion 64 that comes into contact with the excrement. When the excrement comes into contact with the contact portion 64, the health condition of the user can be indicated.

[0058] The inspection member 60 may have a moving section 66 through which components contained in excrement (hereinafter, excrement components) move. In the moving section 66, the excrement components may move by capillary action. The excrement components may include the detection target. The moving section 66 may have an indication moving section 66A through which the excrement components move from the contact section 64 to the display section 62, and a terminal moving section 66B through which the excrement components move in a direction away from the display section 62. The indication moving section 66A may have a first indication moving section 66A1 from the contact section 64 to the first display section 62A, and a second indication moving section 66A2 through which the excrement moves between the multiple display sections 62 (in the embodiment, from the first display section 62A to the second display section 62B). The terminal moving section 66B is a section through which the excrement components and the like that have passed through the display section 62 move.

[0059] To test the health condition, for example, immunochromatography can be used. In the immunochromatography, the contact section 64 with which the excrement comes into contact may be composed of, for example, a pad (which may be called a sample pad or specimen pad). The excrement components that come into contact with the contact section 64 move through the display movement section 66A. Specifically, the excrement components move from the first display movement section 66A1 to the display section 62. The display movement section 66A may contain an antibody (labeled antibody) that reacts with the detection target (antigen). The portion of the first display movement section 66A1 that contains the antibody may be composed of, for example, a conjugate pad. In the first display movement section 66A1, the excrement components, the complex formed by the antigen-antibody reaction with the detection target contained in the excrement components, and the labeled antibody may move by capillary action. The portion to which these chemical substances move may be composed of, for example, a membrane. The display section 62 is an area that contains an indicator (capture antibody). The first display section 62A may include a capture antibody that captures (binds) the formed complex. The first display section 62A changes color when the complex is captured by the capture antibody. The first display section 62A may be called a test line. The labeled antibody and excrement components may migrate through the second display migration section 66A2 and reach the second display section 62B from the first display section 62A.

[0060] The second display section 62B may contain a capture antibody different from that of the first display section 62A. The capture antibody of the second display section 62B may capture a complex different from the complex captured by the first display section 62A, or may capture a labeled antibody. The second display section 62B changes color when the complex or the labeled antibody is captured. The second display section 62B, which captures the labeled antibody, may be called a control line. The excrement components that have passed through the display section 62 (i.e., the components that have not been captured by the capture antibody) move through the terminal movement section 66B. The terminal movement section 66B may be composed of a membrane. The terminal movement section 66B may also have an adsorption pad that absorbs the excrement components that have passed through the display section 62. Instead of the adsorption pad, the excrement components that have passed through the display section 62 may be absorbed by the absorbent core 20. When the immunochromatography method is used, the display section 62 and the contact section 64 are arranged at different positions. Therefore, in this case, the display portion 62 and the touch portion 64 are different.

[0061] Also, for example, a test strip method can be used to test the health condition. In the test strip method, the excrement (detection target) can be directly contacted with the display section 62 containing an indicator. Therefore, the display section 62 and the contact section 64 may be the same. Note that, in order to guide the excrement (detection target) to the display section 62, the test member 60 may have a contact section 64 and a moving section 66 (a section not containing an indicator) that are different from the display section 62.

[0062] The test member 60 may be any material that can hold or contain an indicator, and may be made of any material, such as paper, nonwoven fabric, or woven fabric.

[0063] The test member 60 may be biased to one side in the front-rear direction L. As shown in FIG. 1, the center CT of the test member 60 in the front-rear direction L may be located forward of the center CL of the absorbent article 1 in the front-rear direction L. Also, the display unit 62 may be biased to one side in the front-rear direction L. The display unit 62 may be located forward of the center CL of the absorbent article 1, and the display unit 62 may be located forward of the central region S3. The display unit 62 may be disposed in the front side region S1. As a result, the display unit 62 is disposed at a position away from the excretion opening, and thus it is possible to prevent the color of the display unit 62 from being difficult to see due to excrement. In particular, in a supine sleeping position, excrement is unlikely to diffuse to the front side region S1, and therefore it is possible to prevent the deterioration of the visibility of the color due to excrement. Also, in the test member 60 using the inochromatography method, it is unlikely for excrement to come into direct contact with the display unit 62, and therefore it is possible to accurately display the health condition.

[0064] Furthermore, the contact portion 64 may be biased to one side in the front-rear direction L. The contact portion 64 may be located forward of the center CL of the absorbent article 1. The contact portion 64 may be disposed in the crotch region (not shown). Since excrement comes into contact with the contact portion 64 more easily, the indicator portion is more likely to change color, making it easier for the user to check their health condition. The contact portion 64 may be located more inward in the front-rear direction L than the indicator portion 62.

[0065] As shown in Fig. 3, at least a portion of the test member 60 may overlap the adhesive portion 50 in the thickness direction T. At least one of the display portion 62, the contact portion 64, and the moving portion 66 may overlap the adhesive portion 50. As shown in Fig. 2, the entire test member 60 may overlap the adhesive portion 50 in the thickness direction T. This fixes the test member 60 to the worn article, making it less likely for the test member 60 to shift in position due to the movement of the user wearing the absorbent article 1. This makes it possible to prevent the test member 60 from being difficult to reach due to shifting in position, and allows the health condition to be displayed with high accuracy.

[0066] The color difference ΔE between the skin side sheet 30 and the display part 62 after coloring is 0.6 or more. The color difference ΔE between the skin side sheet 30 and the display part 62 after coloring is preferably 1.2 or more, more preferably 3.0 or more, even more preferably 5.0 or more, and even more preferably 7.0 or more. As shown in Figs. 1 and 3, an indication region IR overlapping with the indication part 62 in the thickness direction T and a surrounding region SR which is a region around the inspection member 60 may be provided. For example, when the absorbent article 1 is a panty liner, the surrounding region SR is a region within, for example, 50 mm from the inspection member 60. When the absorbent article 1 is viewed from the skin side T1, the maximum color difference ΔE between the surrounding region SR and the indication region IR after the indication part 62 has been colored may be 0.6 or more. The maximum color difference ΔE between the surrounding region SR and the display region IR after color development is preferably 1.2 or more, more preferably 3.0 or more, even more preferably 5.0 or more, and even more preferably 7.0 or more.

[0067] The color difference ΔE between the display section 62 after coloring and a portion of the inspection member 60 adjacent to the display section 62 may be 0.6 or more. The color difference ΔE between the display section 62 after coloring and the excrement to be excreted into the absorbent article 1 may be 0.6 or more. The color difference ΔE between the display section 62 after coloring and the excrement to be excreted into the absorbent article 1 is preferably 1.2 or more, more preferably 3.0 or more, even more preferably 5.0 or more, and even more preferably 7.0 or more. For example, when the absorbent article 1 is a napkin or liner, the excrement is blood (menstrual blood) or vaginal discharge. Since blood is generally darker in color than vaginal discharge, the display section 62 may contain an indicator in which the color difference ΔE between the display section 62 after coloring and blood (menstrual blood) is in the above-mentioned range. When the absorbent article 1 is a disposable diaper, the excrement is feces or urine. When the excrement to be detected is urine, the display unit 62 may contain an indicator that causes the color difference ΔE between the display unit 62 after color development and urine to be within the above-mentioned range.

[0068] The skin side sheet 30 may be selected according to the color (wavelength) of the display section 62 after coloring. For example, when the color of the display section 62 after coloring is orange (590-620 nm) or red (620-750 nm), a skin side sheet 30 having a visible light transmittance of a predetermined value (e.g., 60%) or more in the entire range of 590-750 nm may be used. When the color of the display section 62 after coloring is green (495-570 nm) or yellow (570-590), a skin side sheet 30 having a visible light transmittance of a predetermined value (e.g., 60%) or more in the entire range of 495-590 nm may be used. When the color of the display section 62 after coloring is purple (380-450 nm) or blue (450-495), a skin side sheet 30 having a visible light transmittance of a predetermined value (e.g., 60%) or more in the entire range of 380-495 nm may be used.

[0069] The color difference ΔE is measured by using a colorimeter to measure the color of two points (two areas) to be measured, and the color difference is calculated based on the CIE1976(L) standard specified in JIS Z 8781-4:2013 and JIS Z 8730:2009. * a * b *It can be calculated by comparing the values ​​quantified based on the color space. * The difference in values ​​is ΔL * , a * The difference is Δa * , b * The difference between the values ​​is Δb * Then, the color difference ΔE is calculated by the following formula: ΔE = [(ΔL * ) 2 +(Δa * ) 2 +(Δb * ) 2 ] 1 / 2 It is calculated by: An example of the colorimeter is eXact Basic (product number: NGHXRB2BJ) manufactured by X-Rite.

[0070] As described above, in the absorbent article 1 according to the embodiment, the color difference between the skin side sheet 30 and the indicator 62 after coloring is 0.6 or more, so that the color of the indicator 62 after coloring is unlikely to resemble the color of the skin side sheet 30, making it easy to visually confirm the indicator 62 after coloring. The user can easily determine whether or not the indicator 62 has changed color without removing the test member 60 from the absorbent article 1, making it easy to check the user's health condition simply and accurately.

[0071] The visible light transmittance of the top sheet 31 may be 60% or more. This allows the user to more clearly see the color of the display section after coloring through the top sheet, making it easier for the user to know whether the display section has changed color or not.

[0072] The surface sheet 31 may have a basis weight of 90 gsm or less and a thickness of 5 mm or less. This makes it difficult for the surface sheet 31, which is disposed closer to the skin-facing side T1 than the inspection member 60, to interfere with the visibility of the color of the display unit 62 after the coloring, making it easier to know whether the display unit 62 has changed color.

[0073] Furthermore, the center CT of the inspection member 60 in the front-rear direction L may be located forward of the center CL of the absorbent article 1 in the front-rear direction L. When a user places the worn article to which the absorbent article 1 is fixed around both legs and moves the absorbent article 1 away from the crotch area, the user can more easily visually check the portion of the absorbent article 1 in front of the center CL compared to the portion behind the center CL. This makes it easier for the user to visually check the inspection member 60 that is located forward of the center CL. This makes it easier to know whether the indicator 62 has changed color, and makes it easier to simply check the user's health condition.

[0074] Also, at least a part of the test member 60 may overlap with the adhesive portion 50 in the thickness direction T. The area overlapping with the adhesive portion 50 in the thickness direction T adheres to the worn article via the adhesive portion 50. Therefore, the area overlapping with the adhesive portion 50 in the thickness direction T does not float up from the worn article and is less likely to come into contact with the body of the user, compared to the area not overlapping with the adhesive portion 50 in the thickness direction T. By overlapping at least a part of the test member 60 with the adhesive portion 50, it is possible to reduce the separation of the test member 60 from the worn article. This makes it difficult for the test member 60 to continue to receive force from the body of the user, and makes it possible to make the function of the test member 60 less likely to deteriorate. Therefore, it is possible to maintain the accuracy of the coloring of the display portion 62, and to accurately check the health condition of the user.

[0075] Furthermore, the non-skin side sheet 40 may be a sheet that is liquid impermeable and breathable. This can reduce stuffiness of the absorbent article 1 compared to when the non-skin side sheet 40 is a non-breathable film. This can reduce false reactions of the test member 60 due to the user's sweat, making it easier for the user to accurately check their health condition.

[0076] Furthermore, the maximum color difference ΔE between the surrounding region SR and the display region IR after the display unit 62 has changed color may be 0.6 or more. This allows the user to easily visually recognize the display unit 62 after the change in color by viewing the absorbent article 1 from the skin-facing side. The user can easily determine whether the display unit 62 has changed color without removing the test member 60 from the absorbent article 1, and can easily and accurately check the user's health condition.

[0077] (4) Example of changes The absorbent article 1 according to the modified example will be described with reference to Figures 5 to 13. Note that in the following, description of the same contents as those already described will be omitted.

[0078] The absorbent article 1 according to the first modified example will be described with reference to Fig. 5. As shown in Fig. 5, the skin side sheet 30 may have a recess 40p recessed toward the non-skin side T2 from the surrounding area. The thickness of the skin side sheet 30 at the recess 40p may be 5 mm or less. The density of the skin side sheet 30 at the recess 40p may be 18 g / cm 3 or less. The skin side sheet 30 may have protruding portions 40q protruding toward the skin side T1 more than the surrounding area. The recessed portions 40p and the protruding portions 40q may be arranged alternately in the front-rear direction L. The recessed portions 40p and the protruding portions 40q may extend in the width direction W. The skin side sheet 30 may be, for example, a concave-convex sheet manufactured using a spunlace nonwoven fabric.

[0079] The recess 40p may overlap the contact portion 64 in the thickness direction T. In the recess 40p, excrement flows toward the non-skin side T2 from a position closer to the contact portion 64 than around the recess 40p, so that the excrement can more easily reach the contact portion 64. This makes it easier for the display portion 62 to change color and shortens the time it takes for the display portion 62 to change color, making it easier for the user to check their health condition.

[0080] The recesses 40p may overlap the indicator 62 in the thickness direction T. Since the thickness of the skin side sheet 30 is thin in the recesses 40p, the color of the indicator 62 after coloring is easily visible. This makes it easy to know whether the indicator 62 has changed color.

[0081] The absorbent article 1 according to the second modification will be described with reference to FIG. 6. The recesses 40p and the protrusions 40q may be arranged alternately in the width direction W. The recesses 40p and the protrusions 40q may extend in the front-rear direction L. The recesses 40p may overlap the display section 62 in the thickness direction T. When multiple display sections 62 are arranged in the front-rear direction L, the recesses 40p can extend across the multiple display sections 62. As a result, since the thickness of the skin side sheet 30 is thin in the recesses 40p, the colors of the multiple display sections 62 after coloring can be easily seen. As a result, it is easy to know whether the display section 62 has changed color. The recesses 40p may overlap the contact section 64 in the thickness direction T.

[0082] The absorbent article 1 according to the third modified example will be described with reference to FIG. 7. The recesses 40p may be formed by squeezing the skin side sheet 30 in the thickness direction T. The recesses 40p formed by squeezing may overlap the contact portion 64 in the thickness direction T. Since the excrement flows toward the non-skin side T2 from a position close to the contact portion 64, the excrement can easily reach the contact portion 64. In addition, squeezing increases the density of the skin side sheet 30 in the recesses 40p, so that the excrement can be easily drawn in by capillary action. As a result, the excrement can easily reach the contact portion 64. This shortens the time it takes for the display portion 62 to change color, making it easier for the user to check their health condition.

[0083] The absorbent article 1 according to the fourth modified example will be described with reference to Fig. 8. The center CT in the front-rear direction L of the inspection member 60 may be located rearward of the center CL of the absorbent article 1. The display unit 62 may be located rearward of the center CL of the absorbent article 1, and may be located rearward of the central region S3. The display unit 62 may be disposed in the rear side region S2. This allows the display unit 62 to be disposed away from the excretion opening, thereby preventing the color of the display unit 62 from being difficult to see due to excrement.

[0084] Furthermore, the contact portion 64 may be located rearward of the center CL of the absorbent article 1. The contact portion 64 may be disposed in the crotch region (not shown). The contact portion 64 may be located inward in the front-rear direction L from the display portion 62. Since the contact portion 64 is more likely to come into contact with excrement, the display portion is more likely to change color, and the user can more easily check his / her health condition. The contact portion 64 may be located inward in the front-rear direction L from the display portion 62. In particular, when lying on one's back, the user's excrement (particularly bodily fluids) flows backward due to gravity, and the excrement is more likely to reach the contact portion 64 located rearward of the center in the front-rear direction of the absorbent article. This makes it easier for the display portion 62 to change color, and the user can more easily check his / her health condition. Furthermore, when the sample is something other than urine, the contact portion 64 is positioned away from the urine excretion opening in front of the wearer, reducing false reactions of the test member 60 caused by urine which tends to diffuse, making it easier for the user to accurately check their health condition.

[0085] The absorbent article 1 according to the fifth modified example will be described with reference to FIG. 9. The absorbent article 1 may have a bend guiding section 80 for guiding the bend of the absorbent article 1 in the width direction W provided outside the inspection member 60 in the width direction W. The bend guiding section 80 may have a first bend guiding section 81 in which at least the skin side sheet 30 and the non-skin side sheet 40 are compressed in the thickness direction T along the outer periphery of the absorbent article 1. The bend guiding section 80 may have a second bend guiding section 82 extending in the front-rear direction L on both outer sides of the width direction W of the inspection member 60. The second bend guiding section 82 may be a slit penetrating the absorbent core 20 in the thickness direction T, or may be a compressed section in which at least the absorbent core 20 is compressed in the thickness direction T. The front edge of the second bend guiding section 82 may be located forward of the front edge of the inspection member 60, and the rear edge of the second bend guiding section 82 may be located rearward of the rear edge of the inspection member 60.

[0086] Since the absorbent article 1 is sandwiched between the legs of the user, a force acting inward in the width direction W may be applied when the user narrows the distance between the legs. When force is applied to the inspection member 60, the inspection member 60 may deform, and the function of the inspection member 60 may be deteriorated. The bending guide portion 80 guides the bending of the absorbent article 1, so that the absorbent article 1 is more likely to be bent on the outer side in the width direction W than the inspection member 60. This makes it difficult for the force acting inward in the width direction W to be transmitted to the inspection member 60, and makes it possible to make the function of the inspection member 60 less likely to be deteriorated. Therefore, the accuracy of the coloring of the display portion 62 can be maintained, and the health condition of the user can be checked with high accuracy.

[0087] The absorbent article 1 according to the sixth modified example will be described with reference to FIG. 10. At least a part of the contact portion 64 may be disposed at a position not overlapping with the adhesive portion 50 in the thickness direction T. As shown in FIG. 10, the entire contact portion 64 does not need to overlap with the adhesive portion 50. The area not overlapping with the adhesive portion 50 in the thickness direction T is more likely to float from the worn article and approach the user's body than the area overlapping with the adhesive portion 50 in the thickness direction T. By disposing at least a part of the contact portion 64 at a position not overlapping with the adhesive portion 50, the contact portion 64 can be more likely to approach the user's body and come into contact with excrement. This makes it easier for the display portion 62 to change color, making it easier for the user to accurately check their health condition.

[0088] The absorbent article 1 according to the seventh modified example will be described with reference to FIG. 11. The skin side sheet 30 may have an intermediate sheet 32 ​​disposed between the inspection member 60 and the absorbent core 20. The inspection member 60 may be disposed between the top sheet 31 and the intermediate sheet 32. The intermediate sheet 32 ​​may be a colored sheet. The intermediate sheet 32 ​​may be a second sheet or a core wrap that covers the absorbent core 20. The color difference ΔE between the intermediate sheet 32 ​​and the display part 62 after coloring may be 0.6 or more. This allows the user to easily view the display part after coloring by viewing the absorbent article from the skin side.

[0089] The absorbent article 1 according to the eighth modified example will be described with reference to Figs. 12 and 13. The packaging body 200 includes the absorbent article 1 having the inspection member 60 and a packaging member 100 for individually packaging the absorbent article 1. The packaging member 100 may be a packaging sheet for individually packaging the absorbent article 1. When the absorbent article 1 is used, the packaging member 100 is removed to expose the absorbent article 1 and make it usable. The rigidity of the packaging member 100 is greater than the rigidity of the inspection member 60. Even if the rigidity of the inspection member 60 is low, the rigidity of the packaging member 100 can make the inspection member 60 difficult to bend before the packaging body 200 is opened. This can prevent the inspection member 60 from being damaged before opening and the function of the inspection member 60 from being reduced. The rigidity of each member can be measured using, for example, a KES pure bending tester.

[0090] As shown in Fig. 12, the packaging member 100 may be folded together with the absorbent article 1 at a fold line FL as a base point. In Fig. 12 and Fig. 13, a first fold line FL1 and a second fold line FL2 are formed as the fold lines FL in the absorbent article 1 and the packaging member 100. The first fold line FL1 is formed on the outer side of the inspection member 60 in the front-rear direction L, and the second fold line FL2 is formed on the outer side of the inspection member 60 in the front-rear direction L.

[0091] The fold FL may be formed at a position that does not overlap with the display unit 62 in the thickness direction T. When the display unit 62 is folded, creases may be formed in the display unit 62, which may reduce the visible area of ​​the display unit 62. In addition, the display unit 62 may be damaged by folding the display unit 62, which may reduce the area of ​​the display unit 62 that changes color. By forming the fold FL at a position that does not overlap with the display unit 62 in the thickness direction T, the display unit 62 is not folded, which may suppress a decrease in visibility of the display unit 62 after it changes color.

[0092] Furthermore, the fold FL may be formed at a position that does not overlap with the display moving portion 66A in the thickness direction T. If the display moving portion is folded, the display portion may be damaged by folding, which may impede the transport of components contained in the excrement. In this case, the components contained in the excrement that travel to the display portion are reduced, making it difficult for the display portion to change color. By forming the fold at a position that does not overlap with the display moving portion in the thickness direction, the portion from the contact portion to the display portion is not folded, and the precision with which the display portion changes color can be maintained.

[0093] (5) Examples Examples will be described with reference to Fig. 14. The absorbent articles 1 according to Examples 1 to 6 were evaluated as follows. Fig. 14 shows the results of measuring the visible light transmittance. The vertical axis of Fig. 14 shows the visible light transmittance (%), and the horizontal axis shows the wavelength (nm) of the light used in the measurement.

[0094] (5.1)Visible light transmittance The visible light transmittance of the skin side sheet 30 (top sheet 31) of the absorbent articles 1 according to Examples 1 to 6 was measured using a spectrophotometer (JASCO Corp. V-570). Specifically, the visible transmittance was measured using the skin side sheet 30 of each Example cut to 30 mm x 30 mm. In the following, the range of visible light wavelengths is 380 nm to 750 nm. The measurement conditions are as follows:

[0095] Metering mode: Abs Response:Medium Bandwidth: 2.0nm ·Near infrared: 8.0nm Scanning speed: 1000nm / min ·Starting wavelength: 830nm End wavelength: 350nm Data capture interval: 1.0 nm In Example 1, an SMS nonwoven fabric having a basis weight of 17 gsm was used as the skin side sheet 30. In Example 2, an air-through nonwoven fabric having a basis weight of 17 gsm was used as the skin side sheet 30. In Example 3, a spunbond nonwoven fabric having a basis weight of 17 gsm was used as the skin side sheet 30. In Example 4, a spunbond nonwoven fabric having a basis weight of 30 gsm was used as the skin side sheet 30. In Example 5, a spunlace nonwoven fabric made of cotton and having a basis weight of 30 gsm was used as the skin side sheet 30. In Example 6, an air-through nonwoven fabric having a basis weight of 30 gsm was used as the skin side sheet 30.

[0096] As shown in Fig. 14, in Examples 1 to 5, the visible light transmittance was 60% or more. In Example 6, the visible light transmittance having a wavelength of 393 nm or more was 60% or more. In Examples 1 to 4, the visible light transmittance was 70% or more. In Examples 1 and 2, the visible light transmittance was 80% or more.

[0097] (5.2) Visibility Next, visibility was evaluated for the absorbent articles 1 of Examples 1 to 6. As in the embodiment, an inspection member 60 having a colored display portion 62 was disposed between the skin side sheet 30 and the absorbent core 20. Each Example had the same configuration except for the skin side sheet 30.

[0098] In all of the Examples, the color of the display portion 62 was visible. If the color difference ΔE is 1.2 or more, the color difference can usually be easily recognized, so it was found that in all of the Examples, the color difference between the skin side sheet 30 and the display portion 62 after coloring was 0.6 or more. In Examples 1 to 4, the color of the display portion 62 was easily visible, and particularly in Examples 1 and 2, the color of the display portion 62 was clearly visible.

[0099] In addition, Example 1 had a higher visible light transmittance than Example 3 for visible light having a wavelength of 476 nm or less, and Example 3 had a higher visible light transmittance than Example 1 for visible light having a wavelength of 477 nm or more. Therefore, it was found that Example 1 is particularly preferable when the wavelength of the color of the display unit 62 after coloring is 476 nm or less (purple to blue), and Example 3 is particularly preferable when the wavelength of the color of the display unit 62 after coloring is 477 nm or more (green to red). Similarly, Example 5 had a higher visible light transmittance than Example 6 for visible light having a wavelength of 623 nm or less, and Example 6 had a higher visible light transmittance than Example 5 for visible light having a wavelength of 624 nm or more. Therefore, it was found that Example 5 is particularly preferable when the wavelength of the color of the display unit 62 after coloring is 623 nm or less (purple to orange), and Example 6 is particularly preferable when the wavelength of the color of the display unit 62 after coloring is 626 nm or more (red). Furthermore, in Example 4, even though the basis weight of the skin side sheet 30 was 30 gsm, the visible light transmittance was 70% or more, and the visible light transmittance having a wavelength of 385 nm or more was 75% or more.

[0100] (6) Other embodiments The above-described embodiment and modified examples are merely illustrative, and the present invention may be embodied in other ways. For example, the test member 60 may be disposed on the skin-facing side T1 of the skin-side sheet 30. This makes it easier for the user to directly see the color of the display unit 62 after coloring. The user can easily determine whether the display unit 62 has changed color without removing the test member 60 from the absorbent article 1, and can easily and accurately check the user's health condition.

[0101] The inspection member 60 may be circular. In this case, for example, the contact portion 64 may be disposed on the outer periphery of the inspection member 60, and the display portion 62 may be disposed on the center side of the inspection member 60. This allows the contact portion 64 to come into contact with excrement diffusing in the planar direction more easily than the display portion 62.

[0102] Furthermore, the absorbent article 1 may have a plurality of inspection members 60. The plurality of inspection members 60 may be arranged at intervals in the width direction W. Since the opportunities for the inspection members 60 to come into contact with the contact portions 64 increase, it becomes easier to obtain inspection results during use.

[0103] The absorbent article 1 may also contain a cooling agent. For example, the cooling agent may be menthol (e.g., l-menthol) or essential oil derived from plants (e.g., mint, eucalyptus, nutmeg) that acts on the receptor activation channel (TRPM8) in the nerves of the skin, or alcohol, e.g., methanol and ethanol, that lowers the surrounding temperature by the heat of vaporization. This can reduce false reactions of the testing member 60 due to the sweat of the user.

[0104] In the packaging body 200, the absorbent article 1 may be packaged in the packaging member 100 without being folded. The absorbent article 1 may not have a crease FL for folding. The inside of the packaging member 100 may be sealed. The absorbent article 1 may be removed by breaking the packaging member 100. The packaging member 100 may package one absorbent article 1 or multiple absorbent articles 1 (e.g., two or three absorbent articles 1).

[0105] In the above, the color difference ΔE between the skin side sheet 30 and the display area 62 after coloring may be 2.5 or more. The maximum color difference ΔE between the surrounding region SR and the display area IR after coloring may be 2.5 or more. This allows the user to easily see the display area 62 after coloring. Also, the color difference ΔE between the display area 62 after coloring and the excrement to be excreted into the absorbent article 1 may be 1.2 or more, or may be 2.5 or more. This allows the user to easily see the display area 62 after coloring even if the skin side sheet 30 is soiled with excrement.

[0106] It should be noted that the configurations of the absorbent article 1 according to the above-mentioned embodiment, each modified example, and other embodiments can be appropriately combined. The present invention is not limited to the contents described in this specification. Modifications and changes can be made without departing from the spirit and scope of the present invention as defined by the claims. [Explanation of symbols]
