Disclosure of Invention

Problems to be solved by the invention

In the absorbent article of patent document 1, it is necessary to take out the acquisition member from the absorbent article and examine the excrement, and it takes time until the user of the absorbent article becomes aware of the health condition.

One such case is envisaged: by arranging an inspection member for inspecting the health state of the user between the skin side sheet and the absorbent core instead of the acquisition member, the time required for the user to know the health state is shortened. The user can know the health state by taking out the inspection member having the display portion that develops color based on the excrement from the absorbent article and visually recognizing the display portion.

However, since the skin side sheet is disposed at a position closer to the skin surface side than the inspection member, there is a risk that: it is difficult to visually recognize the display portion and the user cannot confirm the health condition with high accuracy. On the other hand, when the inspection member is taken out from the absorbent article, although the display portion is easy to see, there is a risk that: it takes time to take out the inspection member from the absorbent article, or the user's hand is contaminated with excrement when taking out the inspection member, and the health condition of the user cannot be easily confirmed.

Therefore, an absorbent article provided with an inspection member for inspecting the health condition of a user, which can easily and highly accurately confirm the health condition of the user, is desired.

Detailed Description

(1) Brief description of the embodiments

[ scheme 1]

An absorbent article in which, in the case of a disposable absorbent article,

the absorbent article is provided with:

an absorbent core;

a skin side sheet disposed on the skin surface side of the absorbent core; and

an inspection member which is disposed on the skin surface side of the absorbent core and inspects the health condition of the user,

the inspection member has a display portion that develops color based on the excrement,

the color difference between the skin side sheet and the display portion after color development is 0.6 or more.

According to the absorbent article, the color of the colored display portion is less likely to be similar to the color of the skin side sheet, and the colored display portion can be easily visually recognized. The user can easily grasp whether the display part is colored without taking out the inspection member from the absorbent article, and the health condition of the user can be easily, simply and accurately confirmed.

[ scheme 2]

An absorbent article in which, in the case of a disposable absorbent article,

the absorbent article is provided with:

an absorbent core;

a skin side sheet disposed on the skin surface side of the absorbent core; and

the inspection member has a display portion that develops color based on the excrement.

According to the absorbent article, the user can easily and easily check the health condition of the user with high accuracy.

[ scheme 3]

The absorbent article according to aspect 1 or 2, wherein,

the skin side sheet has a surface sheet disposed on the skin surface side of the inspection member,

the inspection member has a contact portion that comes into contact with the excrement to develop the color of the display portion,

the skin side sheet has a recessed portion recessed toward the non-skin side from the periphery thereof,

the concave portion overlaps with the contact portion in the thickness direction.

In the concave portion of the absorbent article, the excrement is directed toward the non-skin surface side from a position closer to the contact portion than the periphery of the concave portion, and therefore the excrement easily reaches the contact portion. This makes it easy for the display portion to develop color, and the time until the display portion develops color can be shortened, so that the user can easily confirm the health state.

[ scheme 4]

The absorbent article according to claim 3, wherein the concave portion does not overlap with the display portion in the thickness direction.

In the absorbent article, since the concave portion does not overlap the display portion in the thickness direction, even when the user uses the absorbent article for a long time or the user performs a strenuous exercise, members, components, and the like constituting the display portion are not easily brought into direct contact with the skin of the user, and the user can obtain a sense of safety.

[ scheme 5]

The absorbent article according to claim 3 or 4, wherein the inspection member further includes a display moving portion between the display portion and the contact portion, the display moving portion moving the component contained in the excrement from the contact portion to the display portion,

the concave portion does not overlap with the display moving portion in the thickness direction.

In the absorbent article, the inspection member further includes a predetermined display moving portion, and the concave portion does not overlap with the display moving portion in the thickness direction. Therefore, the display moving portion is less likely to be inhibited from functioning by sweat or the like of the user, and even when the user uses the absorbent article for a long time or the user performs strenuous exercise, members, components, and the like constituting the display moving portion are less likely to be in direct contact with the skin of the user, so that the user can obtain a sense of safety.

[ scheme 6]

The absorbent article according to any one of aspects 1 to 5, wherein,

the absorbent article is provided with a fold for folding the absorbent article,

the fold is formed at a position not overlapping with the display section in the thickness direction.

In the case of a display portion that is bent, there is a risk that: the wrinkles are formed on the display portion, so that the area of the display portion that can be visually recognized is reduced. There is also a risk that: the display portion is damaged by the bending of the display portion, and the area of the display portion for color development is reduced.

In the absorbent article, the display portion is not folded by forming the fold line at a position not overlapping with the display portion in the thickness direction, and thus the deterioration of visibility of the display portion after color development can be suppressed.

[ scheme 7]

The absorbent article according to any one of aspects 1 to 6, wherein,

the inspection member has:

a contact portion that is in contact with the excrement to develop the color of the display portion; and

a display moving section for moving the components contained in the excrement from the contact section to the display section,

the fold is formed at a position not overlapping with the display moving portion in the thickness direction.

In the case where the display moving portion is bent, there is a risk that: the display moving portion is damaged by bending of the display moving portion, and thus transportation of components contained in excrement is hindered. In this case, components contained in excrement that moves to the display portion are reduced, and the display portion is less likely to develop color.

In the absorbent article, since the fold is formed at a position not overlapping the display moving portion in the thickness direction, the portion from the contact portion to the display portion is not bent, and the accuracy of color development of the display portion can be maintained.

[ scheme 8]

The absorbent article according to any one of claims 1 to 7, wherein a center in the front-rear direction of the inspection member is located forward of a center in the front-rear direction of the absorbent article.

In a state where a user puts an absorbent article or a wearing article to which the absorbent article is fixed through both legs and separates the absorbent article from the crotch portion, the user can easily visually recognize a portion located on the front side with respect to the front-rear center, as compared with a portion located on the rear side with respect to the center in the front-rear direction (hereinafter, the front-rear center) of the absorbent article.

In the absorbent article, since the center of the inspection member in the front-rear direction is located forward of the center of the absorbent article in the front-rear direction, the user can easily grasp whether or not the display portion is colored, and can easily and simply confirm the health condition of the user.

[ scheme 9]

The absorbent article according to any one of aspects 1 to 8, wherein,

the contact portion is located rearward of a center of the absorbent article in a front-rear direction.

In the absorbent article, the contact portion is located rearward of the center in the front-rear direction of the absorbent article. Therefore, in the supine lying position, the excrement of the user (particularly, body fluid) is directed rearward by gravity, and therefore the excrement easily reaches the contact portion located rearward of the center of the absorbent article in the front-rear direction. This makes it easy for the user to confirm the health status because the display section is easily colored.

[ scheme 10]

The absorbent article according to any one of claims 1 to 9, wherein a curve guide portion that guides a curve in the width direction of the absorbent article is provided at a position further outside in the width direction than the inspection member.

Since the absorbent article is sandwiched by both legs of the user, there are cases where: a force toward the inner side in the width direction is applied as the user narrows the interval of both legs. When a force is applied to the inspection member, the inspection member may be deformed, which may deteriorate the function of the inspection member.

In the absorbent article described above, since the curve guide portion is provided at the outer side in the width direction than the inspection member, the curve guide portion guides the curve of the absorbent article, and the absorbent article is likely to curve at the outer side in the width direction than the inspection member. This makes it difficult for the force directed inward in the width direction to be transmitted to the inspection member, and makes it possible to prevent the function of the inspection member from being degraded. Therefore, the accuracy of the color development of the display portion can be maintained, and the health condition of the user can be confirmed with high accuracy.

[ scheme 11]

The absorbent article according to any one of claims 6 to 10, wherein the absorbent article is selected from the group consisting of a sanitary napkin, a panty liner, an adult incontinence pad and a urine absorption pad.

Since the absorbent article is selected from a predetermined product group, the effects of aspects 6 to 10 are further enhanced.

[ scheme 12]

The absorbent article according to claim 11, wherein the inspection member is configured such that, in the expanded state of the absorbent article, the inspection member entirely overlaps with the absorbent article in the thickness direction.

In the absorbent article, the inspection member is arranged so that the entire inspection member overlaps the absorbent article in the thickness direction in the unfolded state of the absorbent article, and therefore the inspection member is less likely to cause a wearer to feel a sense of discomfort. In addition, the inspection member is less likely to be bent by contact with wearing clothes during wearing.

Further, the means 12 may be dependent on any of the means 1 to 11.

[ solution 13]

The absorbent article according to any one of aspects 1 to 12, wherein,

the absorbent article has:

a non-skin side sheet disposed on a non-skin surface side of the absorbent core; and

a pressure-sensitive adhesive section provided on the non-skin surface of the non-skin side sheet for fixing the absorbent article to a wearing article,

at least a part of the contact portion is disposed at a position not overlapping with the adhesive portion in the thickness direction.

The region not overlapping with the adhesive portion in the thickness direction is likely to float from the wearing article and to approach the body of the user, as compared with the region overlapping with the adhesive portion in the thickness direction.

In the absorbent article, at least a part of the contact portion is arranged at a position not overlapping with the adhesive portion, so that the contact portion can be brought close to the body of the user and easily brought into contact with excrement. This makes it easy for the display unit to develop color and for the user to confirm the health condition with high accuracy.

[ scheme 14]

The absorbent article according to any one of claims 1 to 13, wherein the excrement is menstrual blood or leucorrhea.

In the absorbent article, the excreta is menstrual blood or leucorrhea, and therefore the effect of embodiment 13 can be further exhibited.

The absorbent article according to claim 14, wherein the test object detected by the examination means is selected from the group consisting of metabolites in urine, leukocytes, proteins, glucose, ketone bodies, urobilinogen, bilirubin, ureaplasma, 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, streptococcus a, HBs antibodies, HIV antibodies, TP antibodies, rotavirus, influenza virus, adenovirus, DNA, O-157, cocaine, cannabis, and morphine.

In the absorbent article described above, since the detection object detected by the inspection member is selected from a predetermined group, the effect of the aspect 13 or the aspect 14 can be further exhibited.

Further, the means 15 may be dependent on any of the means 1 to 14.

[ solution 16]

An absorbent article package having an absorbent article and a packaging member, the absorbent article comprising: an absorbent core; a skin side sheet disposed on the skin surface side of the absorbent core; and an inspection member which is disposed on a skin surface side of the absorbent core and inspects a health state of a user, the packaging member packaging the absorbent article, the inspection member having a display portion which develops a color based on excrement,

the packing member has a rigidity greater than that of the inspection member.

In the above package, since the rigidity of the package member is higher than the rigidity of the inspection member, even in the case where the rigidity of the inspection member is low, the inspection member can be made less likely to bend by the rigidity of the package member before the package is opened. This can prevent the inspection member from being damaged before the unsealing and from deteriorating the function of the inspection member.

[ scheme 17]

The package of an absorbent article according to claim 16, wherein the color difference between the skin-side sheet and the display portion after color development is 0.6 or more.

In the above package, a user can easily grasp whether or not the display portion is colored without taking out the inspection member from the absorbent article, and the health condition of the user can be easily, simply, and accurately confirmed.

[ solution 18]

The absorbent article package according to claim 16 or 17, wherein the absorbent article is the absorbent article according to any one of claims 1 to 15.

In the package, the absorbent article according to any one of claims 1 to 15 is the absorbent article according to any one of claims 1 to 15, and therefore the effect of any one of claims 1 to 15 can be exhibited.

According to a preferred embodiment, the skin side sheet has a surface sheet disposed on the skin surface side of the inspection member, and the visible light transmittance of the surface sheet is 60% or more. In this way, the user can more clearly visually recognize the color of the display portion after the color development through the front sheet, and can more easily grasp whether or not the display portion is developed.

According to a preferred embodiment, the skin-side sheet has a top sheet disposed on the skin surface side of the inspection member, and the weight per unit area of the top sheet is 90gsm or less. This makes it difficult for the surface sheet disposed on the skin surface side of the inspection member to obstruct the visibility of the color of the display portion after the color development, and makes it easier to grasp whether or not the display portion is developed.

According to a preferred aspect, the absorbent article has: a non-skin side sheet disposed closer to the non-skin side than the absorbent core; and an adhesive portion provided on a non-skin surface of the non-skin side sheet for fixing the absorbent article to a wearing article, wherein at least a part of the inspection member overlaps the adhesive portion in a thickness direction. The region overlapping the adhesive portion in the thickness direction is tightly attached to the wearing article by the adhesive portion. Therefore, the region overlapping the adhesive portion in the thickness direction does not float from the wearing article, and is less likely to come into contact with the body of the user, as compared with the region not overlapping the adhesive portion in the thickness direction. By overlapping at least a part of the inspection member with the adhesive portion, the separation of the inspection member from the worn article can be reduced. Thus, the inspection member is less likely to be continuously applied with force from the body of the user, and the function of the inspection member is less likely to be degraded. Therefore, the accuracy of the color development of the display portion can be maintained, and the health condition of the user can be confirmed with high accuracy.

According to a preferred aspect, the absorbent article includes a non-skin side sheet disposed on a non-skin side of the absorbent core, and the non-skin side sheet is a sheet having liquid impermeability and air permeability. The moist heat of the absorbent article can be reduced as compared with a case where the non-skin side sheet is a film (film) having no air permeability. This reduces the possibility of the test member being erroneously responded to by the sweat of the user, and makes it easy for the user to confirm the health condition with high accuracy.

According to a preferred aspect, a display region overlapping the display portion in the thickness direction and a peripheral region that is a region around the inspection member are provided, and when the absorbent article is viewed from the skin surface side, the maximum color difference between the peripheral region and the display region after the display portion develops color is 0.6 or more. Since the maximum color difference between the display region and the peripheral region after the display portion is developed is 0.6 or more, the user can easily visually recognize the display portion after the development by viewing the absorbent article from the skin surface side. The user can easily grasp whether the display part is colored without taking out the inspection member from the absorbent article, and the health condition of the user can be easily, simply and accurately confirmed.

(2) Schematic structure of absorbent article

An absorbent article 1 according to an embodiment will be described with reference to fig. 1 to 14. The absorbent article may be an absorbent article such as a sanitary napkin, a panty liner, an adult incontinence pad or a urine absorption pad. In the following embodiments, a disposable sanitary napkin will be described as an example of an absorbent article.

The absorbent article 1 may have a front-back direction L, a width direction W, and a thickness direction T. The front-rear direction L is a direction extending from the front side (ventral side) to the rear side (dorsal side) of the user or a direction extending from the rear side to the front side of the user. The width direction W is a direction orthogonal to the front-rear direction L. The thickness direction T is a direction extending from the skin surface side of the user to the non-skin surface side (T2) or a direction extending from the non-skin surface side of the user to the skin surface side (T1). The thickness direction T is a direction orthogonal to the front-rear direction L and the width direction W. The skin surface side corresponds to a side facing the skin of the user when in use. The non-skin surface side corresponds to a side opposite to the skin surface side in use, that is, a side facing opposite to the skin of the user.

As shown in fig. 1, the absorbent article 1 may have a front side region S1, a rear side region S2, and a central region S3. The front region S1 is located on the front side of the central region S3, and the rear region S2 is located on the rear side of the central region S3. The central region S3 includes a region that abuts the excretory opening (e.g., vaginal opening) of the user. A front region obtained by trisecting the absorbent article 1 in the front-rear direction L may be the front region S1, a rear region may be the rear region S2, and a central region between the front region S1 and the rear region S2 may be the central region S3. When the absorbent article 1 has the wing sections, the central region S3 may be a region from the leading edges of the base sections of the wing sections to the trailing edges of the base sections of the wing sections. The wing portions are portions that are folded back toward the non-skin surface side of the wearing article when the absorbent article 1 is used.

The absorbent article 1 may have an absorbent core 20, a skin side sheet 30, a non-skin side sheet 40, an adhesive portion 50, and an inspection member 60. The absorbent core 20 comprises a liquid-absorbent material. The absorbent material may, for example, comprise at least one of pulp and superabsorbent polymer.

The skin side sheet 30 is disposed on the skin surface side T1 with respect to the absorbent core 20. The skin side sheet 30 may have a surface sheet 31 disposed on the skin surface side T1 with respect to the inspection member 60. The topsheet 31 is opposed to the skin of the user. The top sheet 31 may be composed of a plurality of sheets, and may be composed of a top sheet facing the skin of the user and a sheet disposed at a position T2 on the non-skin surface side of the top sheet and at a position T1 on the skin surface side of the inspection member 60. In the embodiment, the skin side sheet 30 is composed of a top sheet 31. The top sheet 31 (skin-side sheet 30) may be formed of, for example, a spunlace nonwoven fabric, a hot air nonwoven fabric, a spunbond nonwoven fabric, an SMS nonwoven fabric, or the like.

The visible light transmittance of the surface sheet 31 may be 60% or more. Preferably, the visible light transmittance of the surface sheet 31 may be 70% or more, and more preferably, the visible light transmittance of the surface sheet 31 may be 80% or more. The weight per unit area of the surface sheet 31 may be 90gsm or less, may be 30gsm or less, and may be 17gsm or less. The thickness of the surface sheet 31 may be 5mm or less.

The non-skin side sheet 40 is disposed on the non-skin surface side T2 with respect to the absorbent core 20. The non-skin side sheet 40 may have a chassis 41 opposed to the wearing article. The non-skin side sheet 40 may be formed of a liquid impermeable film, for example. The non-skin side sheet 40 may be a sheet having liquid impermeability and air permeability, such as a perforated plastic film.

The adhesive section 50 is provided on the non-skin surface of the non-skin side sheet 40. As shown in fig. 2 and 3, the adhesive portion 50 may be provided in a region overlapping with the absorbent core 20 in the thickness direction T, or may be provided in a region not overlapping with the absorbent core 20 in the thickness direction T. The adhesive part 50 may be provided to the wing part. The absorbent article 1 is fixed to a wearing article by the adhesive section 50.

The inspection member 60 is a member for inspecting the health state of the user. The inspection means 60 displays the health status of the user by means of color development (color change) based on excreta. Examples of the excrement (specimen) include blood (menstrual blood), urine, stool, sweat, leucorrhea, and the like. Examples of the items indicating the health state include physical condition-related (pH, iron deficiency anemia, renal function, myocardial infarction, inflammation/infection, nutritional state evaluation, etc.), pregnancy-related (physiological cycle prediction, ovulation prediction, etc.), mental-related (depression tendency, drugs, etc.). Examples of the target include metabolites in urine (specific gravity of urine), white blood cells, hydrogen ions (pH), proteins, glucose, ketone bodies, urobilinogen, bilirubin, 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, Streptococcus A, HBs antibody, HIV antibody, TP antibody, rotavirus, influenza virus, adenovirus, DNA, O-157, cocaine, marijuana, morphine and the like. The object to be detected is a chemical substance (inorganic substance or organic substance) determined according to the item indicating the health state, and the chemical substance reacts with another chemical substance to cause color development.

The inspection member 60 has a display portion 62 that develops color based on the excrement. The display 62 displays the health status of the user. The display unit 62 may display the health status of the user by the color after the color development, or may display the health status of the user by the presence or absence of the color development. The user can visually determine the color after development and/or the presence or absence of development, thereby confirming the health state. The display portion 62 may contain an indicator that develops color based on excrement.

The indicator may contain a chemical substance (inorganic substance or organic substance) that develops color by reacting with a detection target contained in excrement or a substance derived from the detection target (for example, a complex formed by an antigen-antibody reaction between the detection target and an antibody). The indicator may contain a chemical substance (inorganic substance or organic substance) that develops color by reacting with an antibody (chemical substance that reacts with an antigen-antibody reaction of the detection target) that moves together with excrement.

The display unit 62 may be configured by a plurality of display units having different detection targets. As shown in fig. 1 and 3, the display portion 62 may have, for example, a1 st display portion 62A and a2 nd display portion 62B. The 1 st display unit 62A is located closer to the contact unit 64 than the 2 nd display unit 62B.

The inspection member 60 has a contact portion 64 that contacts excrement. The contact of the excrement with the contact portion 64 can indicate the health condition of the user.

The inspection member 60 may have a moving portion 66 for moving components contained in excrement (hereinafter, excrement components). In the moving part 66, the excrement component may move by a capillary phenomenon. Further, the fecal component may contain a detection target. The moving portion 66 may include a display moving portion 66A for moving the excrement component from the contact portion 64 to the display portion 62, and a tip moving portion 66B for moving the excrement component in a direction away from the display portion 62. The display moving part 66A may have a1 st display moving part 66A1 from the contact part 64 to the 1 st display part 62A, and a2 nd display moving part 66A2 for moving excrement among the plurality of display parts 62 (from the 1 st display part 62A to the 2 nd display part 62B in the embodiment). The distal end moving portion 66B is a portion through which the excrement component and the like passing through the display portion 62 move.

For the examination of the health state, for example, immunochromatography can be used. In the immunochromatography, the contact portion 64 with which the excrement comes into contact may be constituted by a pad (may be referred to as a sample pad or an examinee pad), for example. The excrement component in contact with the contact portion 64 moves in the display moving portion 66A. Specifically, the excrement component moves from the 1 st display moving part 66a1 to the display part 62. The display moving part 66A may contain an antibody (labeled antibody) that reacts with a detection target (antigen). The antibody-containing portion of the 1 st display moving part 66a1 may be constituted by a bonding pad, for example. In the 1 st display moving part 66a1, the excrement component, the complex formed by the antigen-antibody reaction with the detection target contained in the excrement component, and the labeled antibody can move by capillary action. The portion for moving the chemical substance may be formed of a membrane (membrane), for example. The display portion 62 is a region containing an indicator (complementary antibody). The 1 st display part 62A may contain a complementary antibody that complements (binds) the complex formed. The 1 st display part 62A develops color by complementing the complex with a complementary antibody. The 1 st display part 62A may be referred to as a test line. The labeled antibody and the fecal matter component can move in the 2 nd display moving part 66A2 from the 1 st display part 62A to the 2 nd display part 62B.

The 2 nd display part 62B may contain a complementary antibody different from that of the 1 st display part 62A. The complementary antibody of the 2 nd display part 62B may be complementary to a complex different from the complex complementary to the 1 st display part 62A, or may be complementary to a labeled antibody. The 2 nd display portion 62B develops color by supplementing the complex or the labeled antibody. The 2 nd display part 62B that supplements the labeled antibody may be referred to as a control line. The excrement component (i.e., the component that has not been supplemented with the supplemental antibody) that has passed through the display portion 62 moves in the end moving portion 66B. The tip moving portion 66B may be constituted by a diaphragm. The distal end moving portion 66B may have an absorption pad that absorbs the components of the excrement after passing through the display portion 62. The components of the excrement after passing through the display portion 62 may be absorbed by the absorbent core 20 instead of the absorbent pad. In the case of immunochromatography, the display unit 62 and the contact unit 64 are disposed at different positions. Therefore, in this case, the display portion 62 and the contact portion 64 are different.

In addition, for checking the health state, for example, a strip method can be used. In the strip method, the excrement (detection target) can be brought into direct contact with the indicator 62 containing the indicator. Thus, the display portion 62 and the contact portion 64 may be identical. In addition, the inspection member 60 may have a contact portion 64 and a moving portion 66 (a portion not containing an indicator) different from the display portion 62 in order to guide the excrement (the detection target) to the display portion 62.

The inspection member 60 may be any member capable of holding or containing the indicator, and may be made of any material such as paper, nonwoven fabric, or woven fabric.

The inspection member 60 may be biased to one side in the front-rear direction L. As shown in fig. 1, the center CT in the front-rear direction L of the inspection member 60 may be located forward of the center CL in the front-rear direction L of the absorbent article 1. In addition, the display portion 62 may be biased to one side in the front-rear direction L. The display unit 62 may be positioned forward of the center CL of the absorbent article 1, and the display unit 62 may be positioned forward of the central region S3. The display portion 62 may be disposed in the front region S1. Thus, the display portion 62 is disposed at a position away from the excretory opening, and therefore, it is possible to suppress the color development of the display portion 62 from being difficult to visually recognize due to the excretory substance. In particular, in the supine lying posture, since the excrement is less likely to spread to the front region S1, deterioration of visibility of color development due to the excrement can be suppressed. In the inspection unit 60 using immunochromatography, since the excrement is not easily brought into direct contact with the display unit 62, the health state can be displayed with high accuracy.

In addition, 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 the excrement is likely to contact the contact portion 64, the display portion is likely to be colored, and the user is likely to confirm the health state. The contact portion 64 may be located inward of the display portion 62 in the front-rear direction L.

As shown in fig. 3, at least a part of the inspection member 60 may overlap with the adhesive portion 50 in the thickness direction T. At least any one of the display portion 62, the contact portion 64, and the moving portion 66 may overlap with the adhesive portion 50. As shown in fig. 2, the entire inspection member 60 may overlap with the adhesive portion 50 in the thickness direction T. As a result, the inspection member 60 is fixed to the wearing article, and therefore, the positional displacement of the inspection member 60 due to the movement of the user wearing the absorbent article 1 is less likely to occur. This can prevent the excrement from hardly reaching the inspection member 60 due to the positional displacement of the inspection member 60, and can accurately display the health state.

The color difference Δ E between the skin side sheet 30 and the display unit 62 after color development is 0.6 or more. The color difference Δ E between the skin side sheet 30 and the display portion 62 after color development is preferably 1.2 or more, more preferably 3.0 or more, further preferably 5.0 or more, and further preferably 7.0 or more. As shown in fig. 1 and 3, a display region IR overlapping the display portion 62 in the thickness direction T and a peripheral region SR that is a region around the inspection member 60 may be provided. For example, in the case where the absorbent article 1 is a panty liner, the peripheral region SR is a region within, for example, 50mm from the inspection member 60. When the absorbent article 1 is viewed from the skin surface side T1, the maximum color difference Δ E between the peripheral region SR and the display region IR after the display 62 is colored may be 0.6 or more. The maximum color difference Δ E between the peripheral region SR and the display region IR after color development is preferably 1.2 or more, more preferably 3.0 or more, further preferably 5.0 or more, and further preferably 7.0 or more.

The color difference Δ E between the display 62 after color development and the portion of the inspection member 60 adjacent to the display 62 may be 0.6 or more. The color difference Δ E between the display 62 after color development and the excrement to be excreted to the absorbent article 1 may be 0.6 or more. The color difference Δ E between the display 62 after color development and the excrement to be excreted to the absorbent article 1 is preferably 1.2 or more, more preferably 3.0 or more, further preferably 5.0 or more, and further preferably 7.0 or more. For example, in the case where the absorbent article 1 is a sanitary napkin or a panty liner, the excrement is blood (menstrual blood) or leucorrhea. Since the color of blood is usually darker than the white band, the display portion 62 may contain an indicator that the color difference Δ E between the display portion 62 after color development and blood (menstrual blood) is in the above range. In addition, in the case where the absorbent article 1 is a disposable diaper, the excrement is feces or urine. In the case where the excrement to be detected is urine, the display portion 62 may contain an indicator that the color difference Δ E between the display portion 62 after color development and the urine is in the above range.

The skin side sheet 30 may be selected according to the color (wavelength) of the display unit 62 after the color development. For example, when the color of the display portion 62 after color development is orange (590nm to 620nm) or red (620nm to 750nm), the skin side sheet 30 having a visible light transmittance of a predetermined value (for example, 60%) or more over the entire range of 590nm to 750nm may be used. When the color of the display 62 after color development is green (495nm to 570nm) or yellow (570nm to 590nm), the skin side sheet 30 having a visible light transmittance of a predetermined value (for example, 60%) or more over the entire range of 495nm to 590nm may be used. When the color of the display portion 62 after color development is purple (380nm to 450nm) or blue (450nm to 495nm), the skin side sheet 30 having a visible light transmittance of a predetermined value (for example, 60%) or more over the entire range of 380nm to 495nm may be used.

The color difference Δ E can be obtained by measuring two points (two regions) to be measured using a color measuring instrument and comparing values obtained by digitizing the color space according to CIE1976(L × a × b) defined in JIS Z8781-4: 2013 and JIS Z8730: 2009. Specifically, when the difference in L value between two points to be measured is Δ L, the difference in a value is Δ a, and the difference in b value is Δ b, the color difference Δ E can be obtained by the following equation:

ΔE＝[(ΔL*) ² +(Δa*) ² +(Δb*) ² ] ^1/2 。

the color measuring instrument may be eXactbasic (product No. NGHXBB 2BJ) manufactured by X-Rite.

As described above, in the absorbent article 1 of the embodiment, since the color difference between the skin side sheet 30 and the colored display portion 62 is 0.6 or more, the color of the colored display portion 62 is less likely to be similar to the color of the skin side sheet 30, and the colored display portion 62 can be easily visually recognized. The user can easily grasp whether or not the display portion 62 is colored without taking out the inspection member 60 from the absorbent article 1, and can easily, simply and accurately confirm the health condition of the user.

The visible light transmittance of the surface sheet 31 may be 60% or more. In this way, the user can more clearly visually recognize the color of the display portion after the color development through the front sheet, and can more easily grasp whether or not the display portion is developed.

The weight per unit area of the surface sheet 31 may be 90gsm or less, and the thickness of the surface sheet 31 may be 5mm or less. This makes it difficult for the front sheet 31 disposed on the skin surface side T1 of the inspection member 60 to obstruct the visibility of the color of the display 62 after the color development, and makes it easier to grasp whether or not the display 62 is developed.

Further, the center CT in the front-rear direction L of the inspection member 60 may be located forward of the center CL in the front-rear direction L of the absorbent article 1. In a state where the user puts the wearing article to which the absorbent article 1 is fixed on both legs and separates the absorbent article 1 from the crotch portion, the user can easily visually recognize the portion on the front side of the center CL than the portion on the rear side of the center CL of the absorbent article 1. Therefore, the user can easily visually recognize the inspection member 60 disposed in the front of the center CL. This makes it easy to grasp whether or not the display unit 62 is colored, and to easily and simply confirm the health condition of the user.

In addition, at least a part of the inspection member 60 may overlap with the adhesive portion 50 in the thickness direction T. The region overlapping the adhesive section 50 in the thickness direction T is tightly attached to the wearing article via the adhesive section 50. Therefore, the region overlapping with the adhesive portion 50 in the thickness direction T does not float from the wearing article, and is less likely to come into contact with the body of the user, as compared with the region not overlapping with the adhesive portion 50 in the thickness direction T. By overlapping at least a part of the inspection member 60 with the adhesive portion 50, it is possible to reduce the separation of the inspection member 60 from the worn article. This makes it difficult for the inspection member 60 to continuously receive a force from the body of the user, and thus makes it possible to prevent the function of the inspection member 60 from being degraded. Therefore, the accuracy of the color development of the display unit 62 can be maintained, and the health condition of the user can be confirmed with high accuracy.

The non-skin side sheet 40 may be a sheet having liquid impermeability and air permeability. Compared to the case where the non-skin side sheet 40 is a film having no air permeability, the hot flash of the absorbent article 1 can be reduced. This reduces the possibility of the test member 60 being erroneously responded by the sweat of the user, and the user can easily and accurately check the health condition.

The maximum color difference Δ E between the peripheral region SR and the display region IR after the display 62 is colored may be 0.6 or more. Thus, the user can easily visually recognize the colored display unit 62 by viewing the absorbent article 1 from the skin surface side. The user can easily grasp whether or not the display portion 62 is colored without taking out the inspection member 60 from the absorbent article 1, and can easily, simply and accurately confirm the health condition of the user.

(4) Modification example

An absorbent article 1 according to a modification will be described with reference to fig. 5 to 13. Note that the same contents as those mentioned above will not be described below.

An absorbent article 1 according to modification 1 will be described with reference to fig. 5. As shown in fig. 5, the skin-side sheet 30 may have a recessed portion 40p, and the recessed portion 40p may be recessed more than its periphery toward the non-skin surface side T2. The thickness of the skin side sheet 30 at the recessed portion 40p may be 5mm or less. The density of the skin side sheet 30 at the concave portion 40p may be 18g/cm ³ The following. The skin side sheet 30 may have a convex portion 40q, and the convex portion 40q may protrude further than its periphery toward the skin surface side T1. The concave portions 40p and the convex portions 40q may be alternately arranged in the front-rear direction L. The concave portion 40p and the convex portion 40q may extend in the width direction W. The skin side sheet 30 may be an uneven sheet manufactured using, for example, spunlace nonwoven fabric.

The recess 40p may overlap with the contact portion 64 in the thickness direction T. In the concave portion 40p, the excrement is directed from a position closer to the contact portion 64 toward the non-skin surface side T2 than the periphery of the concave portion 40p, and therefore the excrement easily reaches the contact portion 64. This makes it easy for the display unit 62 to develop color, and the time until the display unit 62 develops color can be shortened, so that the user can easily confirm the health condition.

The recess 40p may overlap the display portion 62 in the thickness direction T. In the concave portion 40p, since the thickness of the skin side sheet 30 is small, the color of the display portion 62 after color development can be easily visually recognized. This makes it easy to determine whether or not the display unit 62 is developing color.

An absorbent article 1 according to modification 2 will be described with reference to fig. 6. The concave portions 40p and the convex portions 40q may be alternately arranged in the width direction W. The concave portion 40p and the convex portion 40q may extend in the front-rear direction L. The concave portion 40p may overlap with the display portion 62 in the thickness direction T. When the plurality of display portions 62 are arranged in the front-rear direction L, the recess 40p can extend across the plurality of display portions 62. Thus, in the concave portion 40p, since the thickness of the skin side sheet 30 is small, the colors of the plurality of display portions 62 after color development can be easily visually recognized. This makes it easy to determine whether or not the display unit 62 is developing color. Further, the concave portion 40p may overlap with the contact portion 64 in the thickness direction T.

An absorbent article 1 according to modification 3 will be described with reference to fig. 7. The concave portion 40p may be formed by compressing the skin side sheet 30 in the thickness direction T. The concave portion 40p formed by compression may overlap with the contact portion 64 in the thickness direction T. Since the excrement is directed from the position close to the contact portion 64 toward the non-skin surface side T2, the excrement easily reaches the contact portion 64. Further, the density of the skin side sheet 30 at the concave portion 40p is increased by the compression, and therefore, excrement is easily introduced by the capillary phenomenon. As a result, the excrement easily reaches the contact portion 64. This can shorten the time until the display 62 is colored, and thus the user can easily check the health condition.

An absorbent article 1 according to modification 4 will be described with reference to fig. 8. The center CT of the inspection member 60 in the front-rear direction L 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 the display unit 62 may be located rearward of the central region S3. The display portion 62 may be disposed in the rear region S2. Thus, the display portion 62 is disposed at a position away from the excretory opening, and therefore, it is possible to suppress the color development of the display portion 62 from being difficult to visually recognize due to the excretory substance.

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 of the display portion 62 in the front-rear direction L. Since the excrement is likely to contact the contact portion 64, the display portion is likely to be colored, and the user is likely to confirm the health state. The contact portion 64 may be located inward of the display portion 62 in the front-rear direction L. In particular, in the lying position on the back, the excrement of the user (particularly, body fluid) is directed rearward by gravity, and therefore the excrement easily reaches the contact portion 64 located rearward of the center of the absorbent article in the front-rear direction. This makes it easy for the user to confirm the health status because the display unit 62 is easily colored. Further, when the test body is other than urine, since the contact portion 64 is located at a position distant from the excretion portion of urine on the front side of the wearer, it is possible to reduce the possibility of erroneous reaction of the test member 60 due to urine that is likely to spread, and the user can easily and accurately confirm the health condition.

An absorbent article 1 according to modification 5 will be described with reference to fig. 9. In the absorbent article 1, the curve guide portion 80 that guides the curve in the width direction W of the absorbent article 1 may be provided at a position further outward in the width direction W than the inspection member 60. The curve guide portion 80 may have a1 st curve guide portion 81, and the 1 st curve guide portion 81 is formed by compressing at least the skin side sheet 30 and the non-skin side sheet 40 in the thickness direction T along the outer periphery of the absorbent article 1. The curve guide portion 80 may have 2 nd curve guide portions 82 extending in the front-rear direction L on both outer sides in the width direction W of the inspection member 60. The 2 nd bend guide portion 82 may be a slit penetrating the absorbent core 20 in the thickness direction T, or may be a compressed portion compressing at least the absorbent core 20 in the thickness direction T. The front end edge of the 2 nd curved guide portion 82 may be located forward of the front end edge of the inspection member 60, and the rear end edge of the 2 nd curved guide portion 82 may be located rearward of the rear end edge of the inspection member 60.

Since the absorbent article 1 is sandwiched by both legs of the user, there are cases where: the user narrows the interval between the legs to apply a force toward the inner side in the width direction W. When a force is applied to the inspection member 60, the inspection member 60 may be deformed, which may reduce the function of the inspection member 60. The absorbent article 1 is easily bent at a position on the outer side in the width direction W than the inspection member 60 by guiding the bending of the absorbent article 1 by the bending guide portion 80. This makes it difficult for the force directed inward in the width direction W to be transmitted to the inspection member 60, and makes it possible to prevent the function of the inspection member 60 from being degraded. Therefore, the accuracy of the color development of the display unit 62 can be maintained, and the health state of the user can be confirmed with high accuracy.

An absorbent article 1 according to modification 6 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 may not overlap with the adhesive portion 50. The region not overlapping with the adhesive portion 50 in the thickness direction T is likely to float from the wearing article and to approach the body of the user, as compared with the region 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 brought close to the body of the user and easily brought into contact with excrement. This makes it easy for the display unit 62 to develop a color, and the user can easily and accurately check the health condition.

An absorbent article 1 according to modification 7 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 surface 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 may be a core wrap covering the absorbent core 20. The color difference Δ E between the intermediate sheet 32 and the display unit 62 after color development may be 0.6 or more. Thus, the user can easily visually recognize the colored display portion by looking at the absorbent article from the skin surface side.

An absorbent article 1 according to modification 8 will be described with reference to fig. 12 and 13. The package 200 includes the absorbent article 1 and the packaging member 100, the absorbent article 1 includes the inspection member 60, and the packaging member 100 individually packages the absorbent article 1. The wrapping member 100 may be a wrapping sheet that individually wraps the absorbent article 1. The absorbent article 1 can be used by removing the wrapping member 100 when using the absorbent article 1 to expose the absorbent article 1. The packing member 100 has a rigidity higher than that of the inspection member 60. Even in the case where the rigidity of the inspection member 60 is low, the rigidity of the packaging member 100 can be utilized so that the inspection member 60 is not easily bent before the packaging body 200 is opened. This can prevent the inspection member 60 from being damaged before unsealing, and thus the function of the inspection member 60 from being degraded. Furthermore, the stiffness of the components can be measured, for example, using a KES pure bending tester.

As shown in fig. 12, the packing member 100 may be folded together with the absorbent article 1 with the fold line FL as a base point. In fig. 12 and 13, the absorbent article 1 and the packing member 100 have the 1 st fold FL1 and the 2 nd fold FL2 as folds FL. The 1 st fold FL1 is formed at a position outward in the front-rear direction L from the inspection member 60, and the 2 nd fold FL2 is formed at a position outward in the front-rear direction L from the inspection member 60.

The fold FL may be formed at a position not overlapping with the display portion 62 in the thickness direction T. In the case where the display portion 62 is bent, there is a risk that: the wrinkles formed in the display portion 62 reduce the area of the display portion 62 that can be visually recognized. There is also a risk that: the display portion 62 is damaged by the bending of the display portion 62, and the area of the display portion 62 that performs color development is reduced. By forming the fold FL at a position not overlapping with the display unit 62 in the thickness direction T, the display unit 62 is not bent, and a decrease in visibility of the display unit 62 after color development can be suppressed.

The fold FL may be formed at a position not overlapping with the display moving portion 66A in the thickness direction T. In the case where the display moving portion is bent, there is a risk that: the display portion is damaged by bending of the display portion, and the transport of components contained in excrement is hindered. In this case, components contained in excrement that moves to the display portion are reduced, and the display portion is less likely to develop color. By forming the fold line at a position not overlapping the display moving portion in the thickness direction, the portion from the contact portion to the display portion is not bent, and the accuracy of color development of the display portion can be maintained.

(5) Examples of the embodiments

An embodiment will be described with reference to fig. 14. The absorbent articles 1 of examples 1 to 6 were evaluated as follows. Fig. 14 shows the measurement results of the visible light transmittance. In fig. 14, the vertical axis represents the visible light transmittance (%) and the horizontal axis represents the wavelength (nm) of light used for measurement.

(5.1) visible light transmittance

The visible light transmittance of the skin side sheet 30 (surface sheet 31) of the absorbent article 1 of examples 1 to 6 was measured using a spectrophotometer (japanese spectrophotometer V-570). Specifically, the visible light transmittance was measured using the skin side sheet 30 of each example cut to 30mm × 30 mm. Hereinafter, the wavelength range of the visible ray is set to 380nm to 750 nm. The measurement conditions were as follows.

Photometry mode: abs

In response: middle stage

Bandwidth: 2.0nm

Near infrared: 8.0nm

Scanning speed: 1000nm/min

Start wavelength: 830nm

End wavelength: 350nm

Data acquisition interval: 1.0nm

In example 1, an SMS nonwoven fabric having a unit area weight of 17gsm was used as the skin side sheet 30. In example 2, a hot-air nonwoven fabric having a unit areal weight of 17gsm was used as the skin-side sheet 30. In example 3, a spunbonded nonwoven fabric having a unit areal weight of 17gsm was used as the skin-side sheet 30. In example 4, a spunbonded nonwoven fabric having a unit areal weight of 30gsm was used as the skin-side sheet 30. In example 5, a spunlace nonwoven fabric made of cotton and having a basis weight of 30gsm was used as the skin-side sheet 30. In example 6, a hot-air nonwoven fabric having a unit area weight of 30gsm was used as the skin-side sheet 30.

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 at a wavelength of 393nm or more was 60% or more. In examples 1 to 4, the visible light transmittance was 70% or more. In example 1 and example 2, the visible light transmittance was 80% or more.

(5.2) visibility

Next, the absorbent articles 1 of examples 1 to 6 were evaluated for visibility. As in the embodiment, an inspection member 60 having a colored display unit 62 is disposed between the skin side sheet 30 and the absorbent core 20. In each embodiment, the skin side sheet 30 has the same structure.

In any of the embodiments, the color of the display portion 62 can be visually recognized. Since the color difference can be easily seen if the color difference Δ E is 1.2 or more, it is understood that the color difference between the skin side sheet 30 and the display portion 62 after color development is 0.6 or more in both embodiments. In embodiments 1 to 4, the color of the display portion 62 is easily visible, and in particular, in embodiments 1 and 2, the color of the display portion 62 can be clearly visible.

In addition, example 1 has a higher visible light transmittance in the visible light having a wavelength of 476nm or less than that of example 3, and example 3 has a higher visible light transmittance in the visible light having a wavelength of 477nm or more than that of example 1. Therefore, it is understood that example 1 is particularly preferable when the wavelength of the color of the display portion 62 after color development is 476nm or less (violet to blue), and example 3 is particularly preferable when the wavelength of the color of the display portion 62 after color development is 477nm or more (green to red). Similarly, example 5 has a higher visible light transmittance in visible light having a wavelength of 623nm or less than example 6, and example 6 has a higher visible light transmittance in visible light having a wavelength of 624nm or more than example 5. Therefore, it is understood that example 5 is particularly preferable when the wavelength of the color of the display portion 62 after color development is 623nm or less (purple to orange), and example 6 is particularly preferable when the wavelength of the color of the display portion 62 after color development is 626nm or more (red). In example 4, it is understood that, although the weight per unit area of the skin-side sheet 30 is 30gsm, the visible light transmittance is 70% or more, and the visible light transmittance with a wavelength of 385nm or more is 75% or more.

(6) Other embodiments

The embodiments and modifications described above are intended to be illustrative, and the present invention may be practiced in other embodiments. For example, the inspection member 60 may be disposed closer to the skin surface side T1 than the skin side sheet 30. This makes it easy for the user to visually recognize the color of the display unit 62 after the color development. The user can easily grasp whether or not the display portion 62 is colored without taking out the inspection member 60 from the absorbent article 1, and can easily, simply and accurately confirm the health condition of the user.

The inspection member 60 may be circular in shape. In this case, for example, the contact portion 64 may be disposed on the outer peripheral side 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 be more easily brought into contact with excrement spreading in the planar direction than the display portion 62.

In addition, 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 chance of the inspection member 60 coming into contact with the contact portion 64 increases, the inspection result can be more easily obtained at the time of use.

In addition, the absorbent article 1 may contain a cooling agent. For example, as the psychromes, menthol (e.g., l-menthol), essential oils derived from plants (e.g., mint, eucalyptus, nutmeg), and the like may be used as the psychromes acting on the receptor activation channel (TRPM8) of the nerve located on the skin, and alcohols, such as methanol and ethanol, may be used as the psychromes that lower the ambient temperature by the heat of vaporization. This can reduce the possibility of the test member 60 being erroneously responded to by the sweat of the user.

In the package 200, the absorbent article 1 may be wrapped with the wrapping member 100 without being folded. The absorbent article 1 may not be formed with the fold FL for folding. The interior of the packing member 100 may be sealed. The absorbent article 1 can be taken out by breaking the packing member 100. One absorbent article 1 may be packaged in the packaging member 100, or a plurality of absorbent articles 1 (for example, two or three absorbent articles 1) may be packaged.

In the above case, the color difference Δ E between the skin side sheet 30 and the display portion 62 after color development may be 2.5 or more. The maximum color difference Δ E between the peripheral region SR and the display region IR after color development may be 2.5 or more. This allows the user to easily visually recognize the display unit 62 after the color development. The color difference Δ E between the display 62 after color development and the excrement to be excreted to the absorbent article 1 may be 1.2 or more, or 2.5 or more. Thus, even when the skin side sheet 30 is contaminated with excrement, the user can easily visually recognize the display unit 62 after the color development.

It should be noted that the structures of the absorbent article 1 of the above-described embodiment, each modification, and other embodiments can be appropriately combined. The present invention is not limited to the contents described in the present specification. The present invention can be implemented as modifications and alterations without departing from the spirit and scope of the present invention defined by the claims.
