However, the above-described absorbent article has the following problems.
The absorbent article of Patent Document 1 is provided with an indicator over the entire longitudinal direction of the pocket. The pocket is configured to diffuse body fluid in the product longitudinal direction, and diffuses not only a large amount of body fluid such as urine but also a small amount of body fluid such as sweat. Therefore, if the indicator is provided over the entire longitudinal direction of the pocket, even if a small amount of body fluid such as sweat is discharged, the entire indicator overlapping the pocket may exhibit a color reaction. Therefore, when a small amount of body fluid such as sweat is discharged, there is a possibility that the wear assistant may erroneously recognize that a large amount of body fluid such as urine has been discharged.

  Moreover, the pocket of the absorber of patent document 1 is a part where the fabric weight of the absorbent material which comprises an absorber is low, or the absorbent material is not arrange | positioned. Therefore, in the area where the pocket and the indicator overlap, the ink constituting the indicator may touch the wearer's skin. Therefore, when the indicator is provided over the entire longitudinal direction of the pocket, the ink constituting the indicator may excessively touch the wearer's skin and may irritate the skin.

  Then, this invention suppresses irritation | stimulation to skin in the absorbent article which has the absorber in which the recessed part dented in the thickness direction was formed, and the indicator provided in the non-skin opposing surface side rather than the absorber. Meanwhile, it is an object to appropriately detect the body fluid discharge state.

  In order to solve the problems described above, an absorbent article (absorbent article 1) according to the present disclosure includes a product longitudinal direction (product longitudinal direction L) and a product width direction (product width direction W) orthogonal to the product longitudinal direction.

  On the skin facing surface side of the back sheet 6 is provided an indicator 9 configured to visually change when it comes into contact with moisture. A plurality of indicators 9 are provided extending in the product longitudinal direction and spaced in the product longitudinal direction. The indicator 9 is provided in each of the front waist region S1, the rear waist region S2, and the crotch region S3. The indicator 9 is made of a color change agent that visually changes when it comes into contact with moisture. The color changing agent is applied to the skin facing surface of the back sheet 6.

  FIG. 5 is an enlarged view of a portion C shown in FIG. As shown in FIG. 5, a plurality of indicators 9 are arranged in the crotch center slit 311 </ b> C as the slit 31 and a region overlapping with the periphery thereof. In the area where the crotch center slit 311C is arranged, the absorbent article is adjacent to the first area R1 in which the indicator 9 and the crotch center slit 311C overlap in the plan view of the absorbent article, and in the product longitudinal direction. The second region R2 in which the indicator 9 and the crotch center slit 311C do not overlap with each other in plan view is provided.

  The indicator 9 has a plurality of indicator components 90. The indicator component 90 is circular in plan view. The plurality of indicator components 90 are provided side by side in the product longitudinal direction and are spaced apart in the width direction.

  An indicator configuration group 9A is provided as an aggregate including 20 indicator components. One indicator 9 has four indicator configuration groups. The indicator configuration group 9A extends in the product longitudinal direction and is spaced from the product width direction. Each indicator configuration group 9 </ b> A has 20 indicator configuration units 90. In each indicator configuration group 9A, ten indicator configuration sections 90 are arranged in the product longitudinal direction and two in the product width direction.

  Therefore, one indicator 9 includes 80 indicator components 90. Twenty indicator constituent parts 90 are arranged in the product longitudinal direction and four in the product width direction.

  The distance D1 in the product longitudinal direction between the indicator components 90 is longer than the distance D2 in the product width direction of the indicator components 90. Specifically, the distance D1 in the product longitudinal direction between the indicator constituent portions 90 is 1.5 mm, and the distance D2 in the product width direction between the indicator constituent portions 90 is 1 mm. Further, the distance D3 in the product longitudinal direction between the indicator composition groups 9A is the same as the distance D4 in the product width direction of the indicator composition groups 9A. Specifically, the distance D3 in the product longitudinal direction between the indicator composition groups 9A and the distance D4 in the product width direction between the indicator composition groups 9A are 4 mm.

  A distance D5 in the product longitudinal direction between the indicators 9 is shorter than a length L9 of the indicator 9 in the product longitudinal direction. Specifically, the product longitudinal distance D5 between the indicators 9 is 24 mm, and the product longitudinal length L9 of the indicator 9 is 56 mm. The length L9A in the product longitudinal direction of the indicator configuration group 9A is 26 mm. The diameter of the indicator component 90 is 1 mm.

  The distance in the product longitudinal direction between the indicators 9 is different from the distance in the product longitudinal direction between the central slits. The length L9 of the indicator in the product longitudinal direction is different from the length of the central slit 311 in the product longitudinal direction. The length of the central slit 311 in the product width direction W is longer than the distance D4 in the product width direction of the indicator configuration group 9A and shorter than the length of the indicator 9 in the product width direction.

  The center of the indicator 9 in the product width direction coincides with the center of the central slit 311 in the product width direction. The center of the indicator 9 in the product width direction and the center of the center slit 311 in the product width direction coincide with the center of the absorbent article in the product width direction. In the present embodiment, the configuration in which the centers of the two members in the product width direction coincide with each other is a concept including a configuration in which the distance between the centers of the two members in the product width direction is within 3 mm.

  Further, the indicator 9 extends outward in the product longitudinal direction from the absorbent body 3. The indicator 9 is provided at the front edge of the absorbent article and is provided at the rear edge of the absorbent article. In addition, it is preferable that the indicator 9 is provided in at least one among the front-end edge of an absorbent article, and the rear-end edge of an absorbent article.

(2) Action / Effect In the absorbent article configured as described above, when body fluid is discharged from the wearer, the body fluid is retained in the portion where the absorbent core is disposed, and the body fluid is forward and backward through the slit. To spread. When the body fluid is guided to the slit, the indicator 9 arranged so as to overlap the slit shows a color reaction. In a region where the central slit 311 is disposed in plan view, a first region R1 and a second region R2 are provided adjacent to each other in the product longitudinal direction. That is, the indicator 9 is not provided in a partial region of the center slit 311 in the product longitudinal direction.

  For example, when a small amount of body fluid such as sweat is discharged, the body fluid diffuses in the central slit 311, but hardly diffuses beyond the central slit 311. When such a small amount of body fluid is discharged, only the first region R1 in the region where the central slit 311 is disposed exhibits a color reaction, and the second region R2 does not exhibit a color reaction. That is, only a part of the region where the central slit 311 is arranged exhibits a color reaction. When a small amount of body fluid is discharged, no color reaction is shown over the entire central slit 311, so that excessive reaction of the indicator 9 can be suppressed and erroneous recognition can be suppressed.

  On the other hand, when a large amount of body fluid such as urine is discharged, the body fluid diffuses beyond the region where the central slit 311 is disposed, and not only a part of the region where the central slit 311 is disposed, but also the central slit 311. Other than the above (the portion where the absorbing material is disposed), a color reaction is exhibited. Therefore, the wear assistant can detect that a large amount of body fluid has been discharged.

  As described above, the indicator 9 overlaps a part of the central slit 311 to clarify the difference between the case where a small amount of body fluid is discharged and the case where a large amount of body fluid is discharged. It becomes easy to detect. Therefore, the amount of body fluid discharged by the user can be roughly grasped. In particular, when it is difficult to replace at night or during busy times, it is easy for caregivers and other assistants to wear, such as whether they can continue to use absorbent articles, or if they do not replace absorbent articles Exchange can be judged and the burden of childcare and nursing care can be reduced.

  In addition, since a plurality of central slits 311 are arranged at intervals in the longitudinal direction, body fluid diffuses stepwise by the plurality of central slits 311. The indicator 9 shows a color reaction in stages as the body fluid diffuses. Therefore, it becomes easy to detect the discharge state of body fluid appropriately.

  In addition, since the indicator 9 is not provided in a partial region of the central slit 311 in the product longitudinal direction, even when the entire slit is in close contact with the skin, the stimulation of the ink constituting the indicator 9 to the skin Can be suppressed. In addition, in the absorbent body, a difference in rigidity occurs between a portion where the slit is formed and a portion where the slit is not formed (portion where the absorbent material is disposed). For this reason, a portion where a difference in rigidity occurs, for example, when it is sandwiched between the legs of the wearer at the time of wearing, becomes a folding base point. Therefore, the absorbent article can be fitted to the body, and it is possible to reduce stiffness and discomfort during wearing.

  A central slit 311 and an indicator 9 are provided in the front waist region, the rear waist region, and the crotch region, respectively. When body fluid is guided to each region, the indicator 9 disposed in the front waist region, the indicator 9 disposed in the rear waist region, and the indicator 9 disposed in the crotch region react with each other. The amount can be easily grasped.

  The length in the product longitudinal direction of the slit 31 in the crotch region is longer than the length in the product longitudinal direction of the slit 31 in the front waist region, and is longer than the length in the product longitudinal direction of the slit 31 in the rear waist region. The crotch region is a portion that abuts the wearer's excretion opening. Since the length in the product longitudinal direction of the slit 31 disposed in the crotch region is longer than the length of the slit 31 disposed in the front waist region, etc., a large amount of body fluid is discharged from the wearer. However, the body fluid can be guided before and after the absorber, and the body fluid can be absorbed by the entire absorber. Even when a small amount of body fluid is discharged, the body fluid can be guided to the front and back of the absorber through the slit 31. Therefore, even when a small amount of body fluid is repeatedly discharged, the body fluid can be absorbed by the entire absorbent body.

  The interval in the product longitudinal direction between the plurality of indicators 9 and the interval in the product longitudinal direction between the plurality of central slits 311 are different, and the length in the product longitudinal direction of each indicator 9 and the length in the product longitudinal direction of each central slit 311 are different. Since they are different, the indicator 9 and the central slit 311 are not arranged in the product longitudinal direction, and the first region R1 and the second region R2 can be provided in the central slit 311.

  Since the center in the product width direction of the indicator 9 coincides with the center in the product width direction of the central slit 311 and the interval between the plurality of indicator configuration groups 9A is narrower than the width of the central slit 311, the central slit 311 and the indicator configuration group 9A An overlapping region in the product width direction W can be provided.

  Since the center in the product width direction of the indicator 9 and the center in the product width direction of the central slit 311 coincide with the center in the product width direction of the absorbent article, the indicator 9 and the central slit 311 serve as a mark, and the product width of the absorbent article The center of the direction can be easily grasped. When worn, it becomes easier to align the center of the absorbent article with the center of the wearer's body.

  Since the indicator 9 is disposed on at least one of the front end edge of the absorbent article and the rear end edge of the absorbent article, body fluid such as sweat discharged in a region beyond the absorbent body can be detected.

(3) Other Embodiments As described above, the contents of the present invention have been disclosed through the embodiments of the present invention. However, it is understood that the description and drawings constituting a part of this disclosure limit the present invention. Should not. From this disclosure, various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art.

  Next, an absorbent article according to a modification will be described. In the following description of the modified example, only the configuration different from the above-described embodiment will be described, and the description of the same configuration as the embodiment will be omitted.

  As for the absorbent article which concerns on a modification, the indicator 9 may be provided only in the area | region where the absorber is arrange | positioned. That is, the indicator 9 may not be arranged outside the product longitudinal direction L from the absorbent body. Also with the absorbent article which concerns on the said structure, the discharge | emission state of the bodily fluid discharged | emitted by the absorber can be detected appropriately.

  In the absorbent article according to the modification, the indicator 9 may be disposed not only in the region overlapping the central slit 311 but also in the region overlapping the side slit 312. For example, when a disposable diaper as an absorbent article and a urine collecting pad are used in combination, the body fluid may not be guided to the central slit when the body fluid is discharged, and the indicator 9 overlapping the central slit may not react. is there. However, according to the absorbent article according to the configuration, the body fluid is guided to the outer side in the width direction than the pad in a state where the user is lying sideways, etc., so that the absorbent is overlapped with the side slit 312. The indicator reacts. A caregiver or the like can grasp when the body fluid can be held in the pad by the reaction of the indicator arranged so as to overlap the side slit 312. Especially in home care, it is possible to know the timing of pad replacement.

  As for the absorbent article which concerns on a modification, the indicator 9 may be arrange | positioned in the rear side slit 312R which is easy to produce leakage. When using a disposable diaper as an absorbent article and a urine collection pad in combination, the central part of the absorbent body is difficult to get wet and the rear edge of the absorbent body is easy to get wet, especially the rear edge near the side edge of the absorbent body The edge is easy to get wet. A more suitable replacement timing can be grasped by providing an indicator at the leaking portion. In addition, when it is easy to leak ahead for men etc., you may provide the indicator 9 so that it may overlap with the slit of the front end edge side of the absorber 3. FIG.

  The absorbent article which concerns on a modification is the slit (front center slit and front side) arrange | positioned in the front waist area rather than the length of the product longitudinal direction L of the slit (crotch center slit and crotch side part slit) arrange | positioned in the crotch area. The length in the product longitudinal direction L of the part slit) may be long, and the length in the product longitudinal direction L of the slits (the rear center slit and the rear side slit) disposed in the rear waist region may be long.

  Due to the long length of the slit in the product longitudinal direction L, even a small amount of urine is diffused. In particular, since the length of the product longitudinal direction L of the slit arranged in the front waist region and the length of the product longitudinal direction L of the slit arranged in the rear waist region are relatively long, even a small amount of body fluid is absorbed. The body fluid diffuses to the end of the product 3 in the product longitudinal direction L, and the indicator reacts. It is possible to prompt the user to replace the absorbent article before leaking out.

  As for the absorbent article which concerns on a modification, the pattern of the indicator arrange | positioned in a front waist area and the pattern of the indicator 9 arrange | positioned in a back waist area may differ. The said pattern is the number, length, and area of an indicator. When a wearing assistant such as a caregiver replaces the absorbent article, the front and back of the absorbent article can be grasped by the pattern of the indicator, and the replacement work is facilitated.

  Moreover, as for the absorbent article which concerns on a modification, the low fabric weight part as a recessed part may be provided in the absorber. The low basis weight part is a part where the basis weight of the absorbent material is lower than the surrounding absorbent core. Since the weight of the absorbent material is low, the absorbent material is recessed in the thickness direction from the surrounding absorbent core.
