  In the following description, in a state where the absorbent article 1 in the present embodiment is unfolded, the side positioned on the abdomen side of the human body (wearer) when worn is the front side, the side positioned on the back side is the rear side, and the wearer The side in contact with the wearer is the upper side, the opposite side to the side in contact with the wearer is the lower side, and the direction orthogonal to both the front-rear direction and the vertical direction is the left-right direction.

  The absorbent article 1 is an absorbent pad that is used by being detachably attached to an exterior body (not shown) attached to a human body such as a diaper, a diaper cover, and pants.

The absorbent article 1 is formed so as to cover the wearer's crotch portion from the abdominal side to the back side when worn.
Specifically, for example, as shown in FIGS. 1 to 6, one end portion (front end portion) of the absorbent article 1 forms a ventral side portion 11 positioned on the wearer's ventral side when worn, and the other The end portion (rear end portion) forms a dorsal side portion 12 located on the wearer's back side when worn, and the crotch portion 13 is located between the abdominal side portion 11 and the dorsal side portion 12 at the inseam of the wearer. Form.
The back side portion 12 is formed longer in the front-rear direction than the abdominal side portion 11 and longer in the left-right direction than the abdominal side portion 11 and the crotch portion 13. Thereby, the wearer's back side can be widely covered by the back side portion 12.
Further, both edge portions of the crotch portion 13 form two leg surrounding portions 14 located around the wearer's leg when worn from the abdominal side portion 11 to the back side portion 12. The leg surrounding portions 14 and 14 are each provided with a flat gather elastic member 141 such as rubber thread, and the flat gather elastic member 141 forms a flat gather. Thereby, since it fits elastically around a wearer's leg, while being able to suppress side leakage, it is easy to follow a wearer's body movement, and the absorptive article 1 becomes difficult to shift. Moreover, since the absorbent article 1 is naturally curved by the flat gather, a three-dimensional gather (described later) can be brought into close contact with the wearer's inseam.

  The absorbent article 1 has a liquid-permeable surface sheet 20 provided on the contact surface side (upper side) with the wearer at the time of wearing and an impermeability provided on the opposite side (lower side) from the contact surface with the wearer at the time of wearing. The liquid back sheet 30, the absorbent body 50 interposed between the top sheet 20 and the back sheet 30, and both side edges in the width direction of the absorbent body 50 on the top sheet 20 side (left side edge and right side edge) ) And gather sheets 40, 40 provided along the longitudinal direction (front-rear direction) of the absorbent article 1.

The topsheet 20 forms a surface that comes into contact with the wearer when the absorbent article 1 is worn, and is provided on the upper side of the absorbent body 50. The topsheet 20 receives body fluid and transports it to the absorbent body 50. This is a sheet.
Examples of the liquid-permeable sheet include a net-like sheet material obtained by plain weaving of yarn such as nylon and polyethylene terephthalate, a film sheet material formed with a large number of through holes, a film sheet material such as polyethylene and polypropylene, and liquid permeability. A woven fabric and a non-woven fabric are suitable, and a nonwoven fabric is particularly suitable. Nonwoven fabrics include olefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, synthetic fibers such as polyamides, regenerated fibers such as regenerated cellulose fibers such as rayon and cupra, and natural fibers such as natural cellulose fibers such as cotton. As the fiber material, one produced by a known technique such as spun lace, air through, point bond, air laid, spun bond, needle punch or the like can be used.

The back sheet 30 is a liquid-impermeable sheet that is provided on the lower side of the absorbent body 50 and plays a role of preventing body fluid or the like from seeping out and leaking out of the absorbent article 1.
The liquid-impervious sheet is preferably a sheet material having at least water shielding properties such as polyethylene or polypropylene, and is preferably a sheet material having moisture permeability from the viewpoint of preventing stuffiness. As a sheet material having this water barrier property and moisture permeability, for example, a sheet is formed by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretched in a uniaxial or biaxial direction. The microporous sheet material obtained by is preferably used.
In addition, a laminated nonwoven fabric composed of a film layer having liquid impermeability and a nonwoven fabric layer having air permeability may be used. A laminated nonwoven fabric is a nonwoven fabric called a laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, for example, and is a nonwoven fabric having both liquid impermeability and air permeability.

The gather sheets 40, 40 are respectively provided on both side edges along the longitudinal direction of the absorbent body 50 from the abdominal side part 11 to the back side part 12 on the top sheet 20 side.
The outer portions of the gather sheets 40, 40 in the width direction (left-right direction) are fixed to the top surfaces of the top sheet 20 and extending portions 511, 511 (described later) on the side of the absorber 50. Moreover, the width direction inner part of the gather sheets 40, 40 is not fixed to the top sheet 20 and the extending portions 511, 511, and for three-dimensional gathers such as rubber thread along the longitudinal direction (front-rear direction). An elastic member 401 is provided, and a pair of three-dimensional gathers are formed that can stand upright and can be deformed in a stretchable manner in accordance with the wearer's body shape.

The absorbent body 50 is disposed at a position extending from the abdominal side portion 11 through the crotch portion 13 to the back side portion 12 and plays a role of absorbing water-like components such as urine as a body fluid when the absorbent article 1 is used. It is.
Specifically, for example, as shown in FIGS. 4 to 6, the absorbent body 50 is made of an absorbent material such as cotton or pulp, a sheet-like base material such as fiber or film, and a high absorbent polymer such as a superabsorbent polymer. An absorbent core 52 formed by combining a water absorbent resin and a crepe paper 51 as a water absorbent packaging sheet for packaging the absorbent core 52 are provided. Here, in FIG.4 and FIG.5, the external shape of the crepe paper 51 is represented by the virtual line (two-dot chain line).
Examples of the superabsorbent resin include carboxymethyl cellulose, polyacrylic acid and salts thereof, acrylate polymer cross-linked product, starch-acrylic acid graft copolymer, starch-acrylonitrile graft copolymer hydrolyzate, polyoxyethylene cross-linked product Products, crosslinked products of carboxymethyl cellulose, polyethylene oxide, polyacrylamide and other partially crosslinked polymers, or a copolymer of isobutylene and maleic acid are preferably used.

The absorbent core 52 is formed such that the length in the left-right direction of the dorsal side portion 12 in the absorbent core 52 is longer than the ventral portion 11 and the crotch portion 13 in the absorbent core 52.
For example, as shown in FIG. 4, the absorber core 52 includes a plurality of partition portions 60 (first partition portions) that partition an area where a predetermined amount of body fluid in the absorber 50 (absorber core 52) is absorbed. 61-5th division part 65) is provided.

The partition part 60 is formed so as to surround a predetermined substantially elliptical region in the absorbent core 52, and the body fluid excreted at a predetermined excretion position in the absorbent article 1 is in the absorbent body 50 (the absorbent core 52). It is arranged based on the diffusion tendency when diffusing at.
Specifically, the 1st division part 61 is a position based on the spreading | diffusion tendency when about 50 cc of bodily fluid is excreted in the predetermined excretion position in the absorbent article 1, for example, and the said 1st division part 61 is concerned. The portion surrounded by is disposed in a portion where the absorption capacity is about 50 cc.
The second partition 62 is, for example, a position based on a diffusion tendency when approximately 100 cc of body fluid is excreted at a predetermined excretion position in the absorbent article 1, and is surrounded by the second partition 62. The portion (including the portion surrounded by the first partition 61) has an absorption capacity of about 100 cc.
Moreover, the 3rd division part 63 is a position based on the spreading | diffusion tendency when about 200 cc of bodily fluid is excreted in the predetermined excretion position in the absorbent article 1, for example, and is enclosed by the said 3rd division part 63 The portion (including the portion surrounded by the second partition 62) has an absorption capacity of about 200 cc.
Moreover, the 4th division part 64 is a position based on the spreading | diffusion tendency when about 300 cc of bodily fluid is excreted in the predetermined excretion position in the absorbent article 1, for example, and is enclosed by the said 4th division part 64 The portion (including the portion surrounded by the third partition 63) has an absorption capacity of about 300 cc.
Moreover, the 5th division part 65 is a position based on the spreading | diffusion tendency when about 400 cc of bodily fluid is excreted in the predetermined excretion position in the absorbent article 1, for example, and is enclosed by the said 5th division part 65 The portion (including the portion surrounded by the fourth partition 64) has an absorption capacity of about 400 cc.
Here, the absorption capacity of the part surrounded by the one partition part 60 is the absorption capacity (absorption capacity) of the entire absorbent article 1 set in advance and the one partition with respect to the entire volume of the absorbent core 52. This is an amount calculated based on the volume of the portion surrounded by the portion 60, and the like.

The partition part 60 is formed by embossing the upper part of the absorber 50 (absorber core 52), for example. Accordingly, the portion of the absorbent core 52 where the partition 60 is formed has a higher density than the other portions and the body fluid is less likely to diffuse. Therefore, the portion surrounded by the single partition 60 in the absorbent core 52 The absorbed body fluid is difficult to diffuse to the outside of the one partition part 60. That is, the partition 60 has a damming effect of blocking body fluid, and the amount of body fluid absorbed in the portion surrounded by one partition 60 is equal to the absorption capacity of the portion surrounded by the one partition 60. If it does not reach, the body fluid absorbed in the part surrounded by the one partition part 60 is difficult to diffuse to the outside of the one partition part 60.
Examples of the embossing include, but are not limited to, embossing only with pressure, heat embossing, ultrasonic embossing, or a combination thereof.

In addition, for example, as shown in FIG. 5, the absorber core 52 has a lower surface cooling sensation presentation unit 70 that presents the amount of body fluid absorbed by the absorber 50 (absorber core 52) by generating a contact sensation. The first lower surface cooling sensation presentation unit 71 to the fifth lower surface cooling sensation presentation unit 75) are provided.
The lower surface cooling sensation presentation unit 70 is associated with the partition unit 60 from the crotch 13 to the back side 12 on the surface (lower surface) of the absorber 50 (absorber core 52) on the back sheet 30 side, with a predetermined interval. Is arranged in. Thereby, a wearer or a person who takes care of the wearer touches the lower surface of the absorbent article 1 and looks for a cold part, and the amount of body fluid absorbed by the absorbent body 50 provided in the absorbent article 1 is reduced. Since it can be grasped, the amount of absorbed body fluid can be grasped even in the dark with the absorbent article 1 being worn.

Specifically, the first lower surface cooling sensation presentation unit 71 is surrounded by the first partition part 61 so that, for example, the entire part surrounded by the first partition part 61 absorbs bodily fluid to cause a contact cooling sensation. It arrange | positions in the line form along the width direction of the absorber core 52 in the position which overlaps with the rear-end part of a part.
In addition, the second lower surface cooling sensation providing unit 72 is disposed, for example, after the portion surrounded by the second partition part 62 so that a contact cooling sensation occurs when the entire part surrounded by the second partition part 62 absorbs body fluid. It arrange | positions in the line form along the width direction of the absorber core 52 in the position which overlaps with an edge part.
In addition, the third lower surface cooling sensation providing unit 73 is disposed, for example, after the portion surrounded by the third partition part 63 so that a contact cooling sensation occurs when the entire part surrounded by the third partition part 63 absorbs body fluid. It arrange | positions in the line form along the width direction of the absorber core 52 in the position which overlaps with an edge part.
In addition, the fourth lower surface cooling sensation providing unit 74 is located, for example, after the portion surrounded by the fourth partitioning portion 64 so that a contact cooling sensation occurs when the entire portion surrounded by the fourth partitioning portion 64 absorbs body fluid. It arrange | positions in the line form along the width direction of the absorber core 52 in the position which overlaps with an edge part.
In addition, the fifth lower surface cooling sensation providing unit 75 is disposed, for example, after the portion surrounded by the fifth partitioning portion 65 so that a contact cooling sensation occurs when the entire portion surrounded by the fifth partitioning portion 65 absorbs body fluid. It arrange | positions in the line form along the width direction of the absorber core 52 in the position which overlaps with an edge part.

The lower surface cooling sensation providing unit 70 can be formed, for example, by applying a predetermined fluid containing an endothermic agent that generates heat by reaction with a body fluid to the lower surface of the absorber core 52 and drying it.
Examples of the endothermic agent include, but are not limited to, salt hydrates such as sodium acetate and sodium carbonate, anhydrous salts such as ammonium chloride and potassium chloride, polyols such as xylitol particles, or combinations thereof. .

Here, the lower surface cooling sensation providing unit 70 disposed on the back side portion 12 is set so that the content of the endothermic agent is larger than that of the lower surface cooling sensation providing unit 70 disposed on the crotch part 13.
Specifically, for example, the fifth lower surface cooling sensation presentation unit 75 is more endothermic than the other lower surface cooling sensation presentation unit 70 (first lower surface cooling sensation presentation unit 71 to fourth lower surface cooling sensation presentation unit 74). It is formed by applying a fluid having a high content. Thereby, in the fifth lower surface cooling sensation presentation unit 75, compared to the first lower surface cooling sensation presentation unit 71 to the fourth lower surface cooling sensation presentation unit 74, heat absorption is likely to occur even for a small amount of body fluid. Before the absorption allowance of the absorbent article 1 is exceeded, the replacement timing of the absorbent article 1 and the like can be notified by contact cooling.

For example, as shown in FIG. 6, the crepe paper 51 includes extending portions 511 and 511 extending from both side edges in the width direction of the absorbent core 52, and the crepe paper 51 is folded back at the extending portion 511. Are fixed to each other.
The upper surface of the extending portion 511 is fixed to the outer portion of the gather sheet 40 in the width direction, and the lower surface of the extending portion 511 is fixed to the end portion of the back sheet 30 in the width direction. That is, the extending portion 511 is sandwiched between the width direction outer side portion of the gather sheet 40 and the width direction end portion of the back sheet 30, and the width direction outer side portion of the gather sheet 40 and the width direction end portion of the back sheet 30. At the same time, the end of the absorbent article 1 in the width direction is configured.

The extension part 511 is provided with an indicator 80 that causes a color change by reaction with body fluid from the abdomen side part 11 to the back side part 12 on the upper surface of the extension part 511.
The indicator 80 can be formed, for example, by applying a predetermined fluid containing a pigment that causes a color change by reaction with a body fluid to the extension portion 511 and drying it.
The dye is arbitrary as long as it is a dye (including a fluorescent dye) that produces a visible color change by reaction with a body fluid.
Here, “color change” refers to color development (coloring), decolorization, hue change, brightness change, saturation change, fluorescence intensity change, etc., or a combination thereof, and is determined visually. It is a possible change.

When the absorbent core 52 absorbs the body fluid, a part of the body fluid diffuses to the extending portion 511 of the crepe paper 51 and reacts with the indicator 80. The part which is absorbing the body fluid in the absorber core 52 can be grasped.
Here, in order to prevent the bodily fluid that has diffused to the extending part 511 from seeping out or leaking out from the outside of the absorbent article 1, the length of the extending part 511 is such that the extending part 511 has the gather sheet 40. It is preferable that the length does not protrude from the back sheet 30 and the outer portion of the gather sheet 40 in the width direction is preferably liquid-impermeable.

Moreover, the scale 90 (1st scale 91-5th scale 95) which can be read from the side which contacts the wearer in the absorbent article 1 is printed by the inkjet etc. in the part of the width direction outer side of the gather sheet 40. .
The color change portion R of the indicator 80 can be seen through the gather sheet 40, and presents the amount of body fluid absorbed by the absorber 50 (absorber core 52) depending on the position of the color change portion R with respect to the scale 90. It can be done.
Here, the visual presentation unit that presents the amount of body fluid absorbed by the absorber 50 (absorber core 52) by visual change is configured by an indicator 80 and a scale 90.

Specifically, the first scale 91 overlaps the rear end portion of the first partition 61 so that, for example, the entire portion surrounded by the first partition 61 can absorb the body fluid. The position is printed together with a numerical value “50 cc” indicating the absorption capacity (about 50 cc) of the portion surrounded by the first partition 61.
In addition, the second scale 92 is, for example, at a position overlapping the rear end of the second partition part 62 so that the entire part surrounded by the second partition part 62 can absorb the body fluid. It is printed together with a numerical value “100 cc” indicating the absorption capacity (about 100 cc) of the portion surrounded by the second partition 62.
Further, the third scale 93 is, for example, at a position overlapping the rear end of the third partition part 63 so that it can be grasped that the entire part surrounded by the third partition part 63 has absorbed the body fluid. It is printed together with a numerical value “200 cc” indicating the absorption capacity (about 200 cc) of the portion surrounded by the third partition 63.
Further, the fourth scale 94 is, for example, at a position overlapping the rear end portion of the fourth partition part 64 so that the entire part surrounded by the fourth partition part 64 can absorb the body fluid. It is printed together with a numerical value “300 cc” indicating the absorption capacity (about 300 cc) of the portion surrounded by the fourth partition 64.
In addition, the fifth scale 95 is, for example, at a position overlapping the rear end of the fifth partition 65 so that the entire portion surrounded by the fifth partition 65 can absorb the body fluid. It is printed together with a numerical value “400 cc” indicating the absorption capacity (about 400 cc) of the portion surrounded by the fifth partition 65.
Therefore, for example, in FIG. 7, since the lower end of the color change portion R of the indicator 80 is coincident with the first scale 91, the entire portion surrounded by the first partition 61 absorbs bodily fluid. It can be grasped.

According to the absorbent article 1 of the present embodiment described above, the liquid-permeable topsheet 20, the backsheet 30, and the absorbent body 50 interposed between the topsheet 20 and the backsheet 30. Provided, at the time of wearing, the abdomen 11 located on the abdomen side of the wearer, the dorsal side 12 located on the dorsal side, the crotch 13 located between the abdomen 11 and the dorsal side 12, It has. Furthermore, a plurality of partition portions 60 formed by embossing the absorber 50 (absorber core 52) and partitioning an area where a predetermined amount of body fluid is absorbed in the absorber 50 (absorber core 52), A presentation unit (corresponding to the partition unit 60 for presenting the amount of fluid absorbed by the absorber 50 (a visual presentation unit and a cooling sensation for presenting the amount of fluid absorbed by the absorber 50 due to visual change) The lower surface cooling sensation presentation unit 70) presents the amount of body fluid absorbed by the absorbent body 50.

Moreover, a user becomes easy to grasp | ascertain a wearer's health condition by grasping | ascertaining the amount of bodily fluid absorbed by the absorber 50 correctly.
In addition, conventionally, a user often selects an absorbent article having a large absorption allowance in order to remove anxiety about oozing out or leaking out of the absorbent article such as body fluid, but the absorbent article 1 absorbs the absorbent article. By accurately grasping the amount of bodily fluid absorbed by the body 50, it is possible to provide a guideline for selecting an absorbent article, thereby suppressing the selection of an absorbent article having a large amount of absorption allowance. Can do.

Moreover, since the absorbent article 1 is provided with the lower surface cooling sensation presentation part 70 as a presentation part, the user can grasp | ascertain the amount of absorbed bodily fluids in the dark with the absorbent article 1 mounted. it can.
Moreover, since the absorbent article 1 can lower the temperature of the body fluid absorbed by the lower surface cooling sensation presentation unit 70, it can suppress the generation of odors and germs, and when the absorbent article 1 is discarded. The occurrence of insects can also be suppressed.

Moreover, according to the absorbent article 1 of this embodiment demonstrated above, the division part 60 is in the spreading | diffusion tendency at the time of the body fluid excreted in the predetermined excretion position diffusing in the absorber 50 (absorber core 52). Arranged based on.
Therefore, since the partition part 60 can restrict | limit more reliably so that a predetermined amount of bodily fluid may be absorbed in the predetermined area in the absorber 50 (absorber core 52), the amount of bodily fluid absorbed by the absorber 50 Can be grasped accurately.

Moreover, according to the absorbent article 1 of this embodiment demonstrated above, the visual presentation part is provided in the scale 90 which can be read from the side which contacts the wearer in the absorbent article 1, and the absorber 50, and body fluid. And an indicator 80 that causes a color change by the reaction of the above.
Therefore, since the amount of body fluid absorbed by the absorber 50 (absorber core 52) can be presented by the position of the color change portion R of the indicator 80 with respect to the scale 90, the amount of body fluid absorbed by the absorber 50 can be accurately grasped. be able to.

Moreover, according to the absorbent article 1 of this embodiment demonstrated above, the absorber 50 is equipped with the absorber core 52 and the water-absorbing crepe paper 51 which packages the absorber core 52, and the crepe paper 51 is the In addition, the absorbent core 52 includes extending portions 511 and 511 that extend from both side edges in the width direction and constitute both end portions in the width direction of the absorbent article 1, and the partition 60 is provided in the absorbent core 52. The scale 90 is provided at both ends in the width direction of the absorbent article 1, and the indicator 80 is provided in the extending part 511.
Therefore, the scale 90 can be read only from the side in contact with the wearer. However, since the visual presentation part is provided at the end in the width direction of the absorbent article 1, the absorbent article 1 is attached. However, if the end portion is turned, the visual presentation portion can be visually recognized.

Moreover, according to the absorbent article 1 of this embodiment demonstrated above, the lower surface cooling sensation presentation part 70 contains the endothermic agent which produces heat absorption by reaction with a bodily fluid, and is on the surface by the side of the back surface sheet 30 of the absorber 50. The crotch part 13 and the back side part 12 are arranged at a predetermined interval.
When the cooling sensation presentation part is continuously provided along the longitudinal direction from the crotch part 13 to the dorsal side part 12, body fluid excreted at a predetermined excretion position diffuses in the absorbent body. In the presenting part, the boundary between the cold part and the non-cold part is unlikely to occur, and the cold part is difficult to grasp. On the other hand, in the absorbent article 1, the lower surface cooling sensation presentation unit 70 is provided intermittently along the longitudinal direction from the crotch part 13 to the back side part 12, and therefore the temperature of each lower surface cooling sensation presentation unit 70 is set. It can be compared and it is easy to grasp the lower surface cooling sensation presentation unit 70 that is cold. Therefore, the amount of body fluid absorbed by the absorber 50 can be accurately grasped.
