  The absorbent article (absorbent article 1) according to the present disclosure includes a longitudinal direction (longitudinal direction L) and a width direction (width direction W) orthogonal to each other, and a crotch region (inseam region S1) disposed in the crotch of the wearer. And an absorber (absorber 30) disposed in the rear side region (rear side region S3) located on the rear side of the crotch region, and extends outward in the width direction from the absorber in the crotch region And a high weight area (high weight area 31) located at the center in the longitudinal direction of the crotch area, and the high weight area. A low weight area (low weight area 32) that is located rearward of the area and has a lower weight of the absorbent material than the high weight area, and a front edge of the low weight area, The distance (L11) in the longitudinal direction from the center in the longitudinal direction is 40 mm or more and 60 m. It is the absorbent article which is the following, Comprising: The said compression part is formed with the pressing part (squeezing part 80), The said pressing part is the some extended in the said longitudinal direction, and is arrange | positioned mutually non-parallel. A longitudinal compression region (longitudinal compression region R81) having a longitudinal compression portion (longitudinal compression portion 81) and sandwiched between the plurality of longitudinal compression portions has higher rigidity than the low weight area, and the low weight per unit area. The gist is that they are respectively arranged on both outer sides in the width direction of the region.

  According to the absorbent article which concerns on this invention, the fitting property with respect to a perineum part can be improved, and the leakage of a bodily fluid can be suppressed, suppressing the discomfort at the time of wear.

It is a top view of an absorptive article in one embodiment. FIG. 1 is a rear view of the absorbent article. It is sectional drawing of the absorbent article along the AA line shown in FIG. It is sectional drawing of the absorbent article along the BB line shown in FIG. It is sectional drawing of the absorbent article along the CC line shown in FIG. It is a top view of an absorber. It is sectional drawing of the absorbent article of the wearing condition on the basis of the BB line of FIG. It is sectional drawing of the absorbent article of the wearing condition on the basis of CC line of FIG. It is the figure which showed typically the deformation | transformation of the absorbent article in the state in which the wearer laid down sideways.

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
A longitudinal direction and a width direction orthogonal to each other;
An absorber disposed in a crotch region disposed in the crotch of the wearer and a rear region located on the rear side of the crotch region;
Wings extending outward in the width direction than the absorbent body of the crotch region,
In the center of the absorbent body in the width direction, a high weight area disposed at the center of the crotch area in the longitudinal direction, and a rear material than the high weight area, and an absorbent material than the high weight area A low basis weight area with a low basis weight, and
The longitudinal distance between the front edge of the low weight area and the longitudinal center of the wing is an absorbent article of 40 mm or more and 60 mm or less,
In the absorber, a pressing part is formed,
The pressing part has a plurality of longitudinal pressing parts extending in the longitudinal direction and arranged non-parallel to each other,
The longitudinal compression area | region pinched | interposed by the said some longitudinal pressing part is absorptive article which has rigidity higher than the said low fabric weight area | region, and is each arrange | positioned on the both outer sides of the said low weight area of the said width direction.

  The portion facing from 40 mm to 60 mm backward from the longitudinal center of the wing is arranged to face the wearer's perineum when worn. A low weight area is disposed in a portion from the center in the longitudinal direction of the wing toward the rear from 40 mm to 60 mm. The low basis weight area has a lower basis weight of the absorbent material than the high basis weight area located at the center in the longitudinal direction of the absorbent body in the crotch area, and has a lower rigidity than the high basis weight area. It is possible to prevent the wearer from feeling uncomfortable by easily deforming when the low weight area hits the perineum of the wearer. Further, the low basis weight area has a lower basis weight of the absorbent material and a smaller thickness than the high basis weight area. For this reason, when the low weight area hits the perineum of the wearer, the low weight area is arranged along the perineum and the absorber is difficult to be deformed so as to be separated from the body. Therefore, the fitting property with respect to the perineum can be improved.

  Moreover, the longitudinal pressing area | region is arrange | positioned in the both outer sides of the width direction of the low fabric weight area | region. Since the plurality of longitudinal pressing parts arranged across the longitudinal pressing area are non-parallel, the longitudinal pressing area has a surface shape and is likely to be a base point for deformation of the low weight area. A force directed from the outer side in the width direction to the inner side in the width direction is applied to the absorbent article when worn. When a force directed from the outside in the width direction toward the inside in the width direction is applied, the low weight area is lower in rigidity than the longitudinal pressing area and is raised toward the wearer side with respect to the longitudinal pressing area. When the low weight area is raised on the wearer side, a gap between the perineum and the absorbent article is less likely to be generated, the fit to the perineum is improved, and leakage of body fluid can be suppressed.

Such an absorbent article,
The longitudinal squeezing part is disposed across the first side region located outside the high weight area in the width direction and the second side region located outside the width area of the low weight area. It is desirable that

  The force from the outer side in the width direction to the inner side in the width direction by the wearer's leg is more strongly applied to the crotch region than the rear side region. Since the longitudinal compressed portion straddles the first side region and the second side region, it becomes easy to transmit the force from the outer side in the width direction to the inner side in the width direction to the rear side region, and the low weight area is Protrusions more easily with the perineum. Therefore, the fitting property to the perineal part is further improved, and the leakage of body fluid can be suppressed.

Such an absorbent article,
It is desirable that the length in the width direction of the longitudinal squeezed region becomes longer as it goes rearward.

  In such an absorbent article, the force toward the inner side in the width direction when worn is strongly applied to the crotch region and becomes weaker from the crotch region toward the rear. Therefore, when the front part and the rear part in the longitudinal compression region are compared, it is difficult for the rear part to be applied with a force toward the inner side in the width direction. Since the length in the width direction of the longitudinal compression region is longer as it goes rearward, the rear portion of the longitudinal compression region tends to maintain the surface shape and is likely to be a starting point of deformation for the low weight area. Therefore, the low weight area between the rear side portions of the longitudinal compression area is easily raised by a weak force. Therefore, the fitting property to the perineal part is further improved, and the leakage of body fluid can be suppressed.

Such an absorbent article,
The pressing part has a plurality of rear pressing parts that extend in the longitudinal direction on the rear side of the longitudinal pressing part and are arranged non-parallel to each other,
The rear compressed areas sandwiched between the plurality of rear compressed sections are higher than the rigidity of the low weight area, and are respectively disposed on both outer sides in the width direction of the low weight area,
The distance between the rear pressing areas is preferably shorter than the distance between the longitudinal pressing areas.

  The force toward the inner side in the width direction of the absorbent article when worn is strongly applied to the crotch region and becomes weaker from the crotch region toward the rear. Since the distance between the rear pressing areas is shorter than the distance between the longitudinal pressing areas, the low weight area between the rear pressing areas is easily raised even by a weak force. Moreover, the low fabric weight area between the rear side compression areas is arranged to face the depression between the heels behind the perineum. By raising the low weight area between the rear-side compressed areas, the fit property from the perineum to the rear increases, and the transmission leakage of body fluid to the rear can be further suppressed.

Such an absorbent article,
The pressing part has a plurality of point-like pressing parts arranged discontinuously,
It is desirable that the point-like compressed portion is provided in the longitudinal compressed region.

  According to such an absorbent article, the rigidity of a longitudinal pressing area | region becomes high with a dotted | punctate pressing part. The difference in rigidity between the longitudinal pressing area and the low weight area becomes larger, and the low weight area easily rises from the longitudinal pressing area as a base point. Therefore, the fitting property to the perineal part is further improved, and the leakage of body fluid can be suppressed.

Such an absorbent article,
The pressing part has a plurality of point-like pressing parts arranged discontinuously,
It is desirable that the point-like compressed part is provided in the longitudinal compressed region and the rear compressed region.

  According to such an absorbent article, the rigidity of a longitudinal pressing area | region and a rear side pressing area | region becomes high by a dotted | punctate pressing part. The low weight area easily rises from the longitudinal pressing area and the rear pressing area from the base point, the fit property from the perineum to the depression between the heels is further improved, and leakage of body fluid can be suppressed.

Such an absorbent article,
The length in the width direction of the high weight area is preferably longer than the length in the width direction of the low weight area.

  According to such an absorbent article, since the length in the width direction of the high weight area located in the center of the crotch area is longer than the length in the width direction of the low weight area, the body fluid can be widened in the high weight area. Can absorb. On the other hand, the length in the width direction of the low weight area is shorter than the length in the width direction of the high weight area, and the area that protrudes toward the wearer has a narrow width and can easily fit the perineum of the wearer.

Such an absorbent article,
Extending in the width direction, having a fold line for folding the absorbent article,
It is desirable that the fold line is separated from the longitudinal pressing region.

  According to such an absorbent article, since the longitudinal pressing area | region and the fold line are spaced apart, the crease | fold by a fold line is not formed in a longitudinal pressing area | region. The shape of the longitudinal pressing part is maintained, and the low weight area is easily raised from the longitudinal pressing part.

Such an absorbent article,
It is desirable that the basis weight of the absorbent material in the low basis weight region is 100 g / m ² or more lower than the basis weight of the absorbent material of the absorbent body located outside in the width direction than the low basis weight region.

The difference between the basis weight of the absorbent material in the low basis weight area and the basis weight of the absorbent material of the absorbent body located on the outer side in the width direction than the low basis weight area is 100 g / m ^2. The difference in rigidity between the absorbers located on the outer side in the width direction becomes remarkable, and the low weight area is likely to rise.

Such an absorbent article,
It is desirable that the center in the width direction of the low weight area is disposed in an area that does not overlap with a joint for attaching the absorbent article to underwear.

  The center in the width direction of the low-weight area is arranged to face the center in the width direction of the perineum when worn. Since the center in the width direction of the low-weight area is disposed in an area that does not overlap with the joint portion, the center is shifted from the area fixed to the undergarment, and tends to be raised on the wearer side. Therefore, the gap between the wearer and the absorbent article is reduced, and leakage can be further reduced.

FIG. 3 is a cross-sectional view of the absorbent article along the line AA shown in FIG. FIG. 4 is a cross-sectional view of the absorbent article along the line BB shown in FIG. FIG. 5 is a cross-sectional view of the absorbent article along the line CC shown in FIG.

  The absorbent article 1 has a longitudinal direction L and a width direction W perpendicular to each other, and a thickness direction T extending from the skin facing surface side T1 of the wearer to the non-skin facing surface side T2. The skin facing surface side T1 corresponds to the side facing the wearer's skin when in use. The non-skin facing surface side T2 corresponds to a side opposite to the skin facing surface side T1, that is, a side facing away from the wearer's skin when used.

  The absorbent article 1 has a crotch region S1, a front side region S2, and a rear side region S3. The crotch region S1 is a region facing the excretion opening of the wearer, for example, the vaginal opening. When the absorbent article 1 is attached to the underwear, the crotch region S1 is a region that is disposed between the legs of the wearer and is disposed between the legs of the wearer. The front side area S2 is located in front of the crotch area S1. The front end edge of the front side region S2 defines the front end edge of the absorbent article 1. The rear side region S3 is located behind the crotch region S1. The rear edge of the rear side region S3 defines the rear edge of the absorbent article 1.

  The absorbent article 1 has a wing 3 and a hip flap 4. The wing 3 and the hip flap 4 extend outward in the width direction W from the outer edge of the absorbent body 30 in the crotch region S1. The wing 3 is provided in the crotch region S1. The front edge of the wing 3 is defined by the root of the wing 3 and corresponds to a portion located on the front side of the two portions recessed most inside in the width direction W. The front edge of the wing 3 defines a boundary between the crotch region S1 and the front side region S2. The rear edge of the wing 3 is defined by the root of the wing 3, and corresponds to a portion located on the rear side of the two portions that are recessed most in the width direction W. The rear edge of the wing 3 defines a boundary between the crotch region S1 and the rear side region S3. The center in the longitudinal direction L of the crotch region S1 coincides with the center 3CL in the longitudinal direction of the wing. The hip flap 4 is provided in the rear side region S3.

  The absorbent article 1 includes a skin sheet 10, a non-skin sheet 20, and an absorber 30. The skin sheet 10 is provided on the skin facing surface side T <b> 1 from the absorbent body 30. The non-skin surface sheet 20 is provided closer to the non-skin facing surface side T2 than the absorber 30. The absorber 30 is provided between the skin sheet 10 and the non-skin sheet 20.

  The absorber 30 is arranged at least in the crotch region S1 and the rear side region S3. The absorber 30 has an absorbent core (not shown) made of an absorbent material that absorbs liquid, and a core wrap (not shown) that wraps the absorbent core. The configuration of the absorber 30 will be described in detail later.

  The skin sheet 10 includes a top sheet 11 and a side sheet 12. The top sheet 11 is a liquid-permeable sheet that transmits liquid such as body fluid. The side sheet 12 covers the outer edge of the top sheet 11 in the width direction W, and extends outward in the width direction W from the top sheet 11. The non-skin surface sheet 20 is a liquid-impermeable sheet.

  As shown in FIG. 2, a non-skin facing surface of the non-skin surface sheet 20 is provided with a joint portion 60 for joining the absorbent article 1 to the undergarment. The joint 60 includes a pair of main body joints 61 disposed in a region overlapping the absorber 30, a pair of wing joints 62 disposed on the wing 3, and a pair of flap joints 63 disposed on the hip flap 4. And having. A pair of main body junction part 61 is arrange | positioned so that it may not overlap with the center of the width direction of an absorber. The pair of main body joint portions 61 are separated in the width direction W and are disposed on both outer sides in the width direction with respect to the center in the width direction of the absorber. The distance in the width direction between the main body joint portions 61 is 10 to 20 mm. The joint 60 is covered with a release sheet (not shown) or a packaging sheet (not shown) for individually packaging the absorbent article before use.

(2) Detailed structure of absorber Next, the structure of the absorber 30 is demonstrated more concretely. The absorber 30 has a plurality of regions with different basis weights of the absorbent material. FIG. 6 is a plan view of the absorber, in which a plurality of regions having different basis weights are provided with different oblique lines. In addition, in FIG. 6, the pressing part mentioned later of an absorber is abbreviate | omitted. The absorbent body 30 includes a high weight area 31, a low weight area 32, a first side area 33, a second side area 34, and a front area 35. The high weight area 31 and the low weight area 32 are provided in the center of the absorbent body 30 in the width direction W. The high weight area 31 is disposed at the center 3CL in the longitudinal direction L of the wing, and is disposed to face the excretion opening (vaginal opening) when worn. The front edge 31F and the rear edge 31R of the high weight area 31 are located in the crotch area S1. The basis weight of the high basis weight area 31 is at least higher than that of the low basis weight area 32. The basis weight of the high basis weight area 31 is 150 g / m ² or more higher than the basis weight of the surrounding areas (the low basis area 32, the first side area 33 and the front side area 35). According to such a configuration, the high weight area 31 is thicker than the surrounding area, and can easily fit the wearer's vaginal opening.

The low weight area 32 is disposed on the rear side of the high weight area 31. The low weight area 32 is adjacent to the high weight area 31. The basis weight of the low basis weight area 32 is at least lower than the basis weight of the high basis weight area 31. The basis weight of the low basis weight area 32 is 100 g / m ² or more lower than the basis weight of the surrounding areas (the high basis weight area 31 and the second side area 34). According to such a configuration, the difference in rigidity between the low weight area 32 and the surrounding area becomes remarkable, and the low weight area 32 is easily raised by being easily deformed when worn.

  The front edge 32F of the low weight area 32 is located in the crotch area S1, and the rear edge 32R of the low weight area 32 is located in the rear area S3. A longitudinal distance L11 (see FIG. 1) between the front edge 32F of the low weight area 32 and the longitudinal center 3CL of the wing 3 is 40 mm or more and 60 mm or less. A portion facing from 40 mm to 60 mm rearward from the center 3CL in the longitudinal direction of the wing is arranged to face the perineum of the wearer. A low weight area 32 is disposed in a portion that is directed backward from 40 mm to 60 mm from the center in the longitudinal direction of the wing. The low basis weight area 32 has a lower basis weight of the absorbent material than the high basis weight area 31 and has a lower rigidity than the high basis weight area 31. The low weight area 32 is easily deformed when it hits the perineum of the wearer, and can prevent the wearer from feeling uncomfortable. Further, the low basis weight region 32 has a lower basis weight of the absorbent material and a smaller thickness than the high basis weight region 31. Therefore, when the low weight area 32 hits the wearer's perineum, the low weight area 32 is arranged along the perineum and the absorber 30 is unlikely to be deformed so as to be separated from the body. Therefore, the fitting property with respect to the perineum can be improved.

  The center of the low weight area 32 in the width direction is arranged in an area that does not overlap with the joint 60 for attaching the absorbent article to the undergarment. More specifically, the center in the width direction of the low weight area 32 overlaps the area between the main body joint portions 61. The center in the width direction of the low weight area 32 is arranged to face the center in the width direction of the perineum when worn. Since the center in the width direction of the low weight area 32 is shifted from the joint portion fixed to the undergarment, it tends to rise to the wearer side. Therefore, the gap between the wearer and the absorbent article is reduced, and leakage can be further reduced.

  The length in the width direction of the high weight area 31 is longer than the length in the width direction of the low weight area 32. The maximum length in the width direction of the high weight area 31 is configured to be longer than the maximum length in the width direction of the low weight area 32. Since the length in the width direction of the high weight area 31 located at the center of the crotch area S1 is longer than the length in the width direction of the low weight area 32, the body weight can be absorbed in a wide width in the high weight area 31. On the other hand, since the length in the width direction of the low weight area 32 is shorter than the length in the width direction of the high weight area 31, the area that protrudes toward the wearer has a narrow width and is easily fitted to the perineum of the wearer.

  The pair of first side regions 33 are regions located on both outer sides in the width direction of the high weight area 31 and extending from the outer edge of the high weight area 31 to the outer edge of the absorber 30. The basis weight of the first side area 33 is higher than the basis weights of the low basis area 32, the front area 35, and the second side area 34. The pair of second side regions 34 are regions that are located on both outer sides in the width direction of the low weight area 32 and extend from the outer edge of the low weight area 32 to the outer edge of the absorber. The basis weight of the second side area 34 is higher than the basis weight of the low basis area 32, the same as the basis area of the front side area 35, and lower than the basis weight of the high basis area 31 and the second side area 34. The second side region 34 of the present embodiment is also arranged on the rear side of the low weight area 32. The front area 35 is located on the front side of the high weight area 31 and the front side of the first side area 33.

  As shown in FIG. 1, a pressing portion 80 is formed in the absorber 30. The pressing part 80 is formed by pressing at least the absorber 30 in the thickness direction T. The pressing part has a longitudinal pressing part 81, a rear pressing part 82, and a point-like pressing part 83.

  The longitudinal pressing part 81 extends in the longitudinal direction L, and a plurality of the longitudinal pressing parts 81 are provided in each first side region 33. The longitudinal pressing unit 81 includes a first longitudinal pressing unit 811 and a second longitudinal pressing unit 812 that are arranged non-parallel to each other. The 1st longitudinal pressing part 811 and the 2nd longitudinal pressing part 812 should just have the part arrange | positioned mutually non-parallel. In this Embodiment, the 1st longitudinal pressing part 811 and the 2nd longitudinal pressing part 812 being non-parallel is that the distance of the width direction of the 1st longitudinal pressing part 811 and the 2nd longitudinal pressing part 812 is changing. .

  The 1st longitudinal pressing part 811 is located in the low fabric weight area | region 32 side, and the 2nd longitudinal pressing part 812 is located in the outer side of the width direction rather than the 1st longitudinal pressing part 811. As for the 1st longitudinal pressing part 811, the part which swelled inside the width direction is located in a line with the longitudinal direction. The second longitudinal pressing portion 812 has a portion that swells outward in the width direction. The front end edge of the first longitudinal pressing portion 811 and the front end edge of the second longitudinal pressing portion 812 are continuous, and the rear end edge of the first longitudinal pressing portion 811 and the rear end edge of the second longitudinal pressing portion 812 are continuous. Yes. The longitudinal pressing region R81 is a region sandwiched between the first longitudinal pressing portion 811 and the second longitudinal pressing portion 812. The rigidity of the longitudinal pressing region R81 is higher than the rigidity of the low weight area 32.

  The longitudinal pressing region R81 is disposed on both outer sides in the width direction of the low weight area 32. It arrange | positions on both sides of longitudinal compression area | region R81. Since the 1st longitudinal pressing part 811 and the 2nd longitudinal pressing part 812 are arrange | positioned non-parallel, the longitudinal pressing area | region R81 tends to become a surface shape, and tends to become a base point of a deformation | transformation of a low weight area. FIG. 7 is a cross-sectional view taken along the line BB in a worn state. A force directed from the outer side in the width direction to the inner side in the width direction is applied to the absorbent article when worn. The force toward the inner side in the width direction is applied to the longitudinal compression region R81 in the crotch region, and is applied to the low weight area 32 through the longitudinal compression region R81. When the force which goes to the inner side of the width direction from the outer side of the said width direction is applied, the low weight area | region 32 protrudes to a wearer side from the surface-shaped longitudinal pressing area | region R81. When the low weight area 32 is raised on the wearer side, a gap between the perineum and the absorbent article is less likely to be generated, the fit to the perineum is improved, and leakage of body fluid can be suppressed.

  The longitudinal pressing portion 81 is disposed across the first side region 33 and the second side region 34. It suffices that at least one of the first longitudinal pressing portion 811 and the second longitudinal pressing portion 812 constituting the longitudinal pressing portion 81 extends to the first side region 33. The force directed from the outer side in the width direction to the inner side in the width direction by the wearer's leg is more strongly applied to the crotch region S1 than the rear side region S3. Since the longitudinal pressing portion 81 straddles the first side region 33 and the second side region 34, the force from the outer side in the width direction toward the inner side in the width direction is easily transmitted to the rear side region S3. The low weight area 32 is more likely to be raised with respect to the perineum. Therefore, the fitting property to the perineal part is further improved, and the leakage of body fluid can be suppressed.

  The length in the width direction of the longitudinal compression region R81 becomes longer toward the rear. The length in the width direction of the longitudinal compression region R81 has changed, and at least part of the longitudinal compression region R81 only needs to be configured longer as the length in the width direction goes rearward. The force toward the inner side in the width direction of the absorbent article when worn is strongly applied to the crotch region S1 and becomes weaker from the crotch region S1 toward the rear. Therefore, when the front portion and the rear portion of the longitudinal compression region R81 are compared, it is difficult for the rear portion to be applied with a force toward the inner side in the width direction. Since the length in the width direction of the longitudinal compression region R81 is longer toward the rear, the rear portion of the longitudinal compression region R81 is likely to be a starting point of deformation with respect to the low weight region 32, and the rear portion of the longitudinal compression region R81. The low basis weight area 32 is easily raised by a weak force. Therefore, the fitting property to the perineal part is further improved, and the leakage of body fluid can be suppressed.

  The rear pressing part 82 extends in the longitudinal direction L on the rear side of the longitudinal pressing part. A plurality of the rear pressing parts 82 are provided in each second side area. The back side pressing part 82 has the 1st back side pressing part 821 and the 2nd back side pressing part 822 arrange | positioned mutually non-parallel. The 1st back side pressing part 821 and the 2nd back side pressing part 822 should just have the part arrange | positioned mutually non-parallel.

  The 1st back side compression part 821 is located in the low weight area | region 32 side, and the 2nd back side compression part 822 is located in the outer side of the width direction rather than the 1st back side compression part 821. A 1st back side pressing part has a part which swelled inside the width direction. As for the 2nd rear side pressing part 822, the part swollen to the outer side of the width direction is located in a line with the longitudinal direction. The front end edge of the first rear side compressed portion 821 and the 822 front end edge of the second rear side compressed portion are connected, and the rear end edge of the first rear side compressed portion 821 and the rear end edge of the second rear side compressed portion 822 are connected. Are lined up. The rear side pressing region R82 is a region sandwiched between the first rear pressing unit 821 and the second rear pressing unit 822. The rigidity of the rear pressing area R82 is higher than the rigidity of the low weight area 32.

  The rear squeezing regions R82 are respectively disposed on both outer sides in the width direction of the low weight area 32. Since the 1st back side compression part 821 and the 2nd back side compression part 822 are arrange | positioned non-parallel, back side compression area | region R82 tends to become a surface shape and tends to become a base point of a deformation | transformation of a low weight area. FIG. 8 is a cross-sectional view taken along the line CC in the wearing state. When the force toward the inner side in the width direction is applied to the absorbent article when worn, the low basis weight region 32 has lower rigidity than the rear side compression region R82, and rises toward the wearer side with the surface side rear side compression region as a base point. . As the low weight area 32 rises to the wearer side with the longitudinal compression area R81 and the rear compression area R82 as the base point, the absorbent article fits into the depression between the perineum and the heel behind the perineum, and the body fluid Leakage can be suppressed.

  The inner edge of the rear pressing part 82 is located on the inner side in the width direction than the inner edge of the longitudinal pressing part 81. A distance W82 between the rear pressing regions R82 is shorter than a distance W81 between the longitudinal pressing regions R81. It is only necessary that the shortest distance between the rear pressing regions is shorter than the shortest distance between the longitudinal pressing regions R81. The force directed to the inner side in the width direction applied to the absorbent article when worn is strongly applied to the crotch region and becomes weaker from the crotch region toward the rear. Since the distance W82 between the rear pressing regions R82 is shorter than the distance W81 between the longitudinal pressing regions R81, the rear pressing region R82 is weaker than the longitudinal pressing region R81, but easily rises due to the weak force. . The low basis weight area | region 32 between back side pressing area | region R82 is arrange | positioned facing the hollow between the back collar parts rather than a perineum part. Therefore, when the low weight area 32 rises, the fit property from the perineum to the rear increases, and the transmission leakage of the body fluid to the rear can be further suppressed.

  Moreover, it is preferable that the distance W81 between longitudinal compression area | regions R81 is 25% or more with respect to the full length of the width direction of the absorber 30. FIG. According to such a structure, the area | region between longitudinal compression area | region R81 is raised toward a wearer side, and the area | region between longitudinal compression area | region R81 becomes easy to fit the clearance gap between bodies.

  Further, the low weight area 32 between the rear compressed areas R82 is raised from the first rear compressed area, and the low weight area 32 between the longer compressed areas R81 is raised from the first long compressed area. Since the 1st back side compression part is located in the inner side of the width direction rather than the 1st longitudinal compression part, the length of the width direction of the field raised to the wearer side between back side compression fields R82 is longitudinal compression field R81. It is shorter than the length in the width direction of the region protruding to the wearer side. As described above, since the region between the rear pressing regions R82 is easily raised even by a weak force, the region is raised at a sharper angle than the region between the longitudinal pressing regions R81 and fits into the gap between the heel portions.

  A plurality of point-like compressed parts 83 are discontinuously arranged. The point-like compressed parts 83 are arranged at intervals in the longitudinal direction and the width direction. Since the point-like squeezed parts 83 are arranged at intervals, the region where the point-like squeezed parts 83 are arranged is easily deformed flexibly according to body deformation. The point-shaped pressing part 83 is provided in the longitudinal pressing area R81. The rigidity of longitudinal compression area | region R81 becomes high by the dotted | punctate pressing part 83. FIG. The rigidity difference between the longitudinal pressing region R81 and the low weight area 32 becomes larger, and the low weight area 32 is easily raised from the longitudinal pressing area R81. Therefore, the fitting property to the perineal part is further improved, and the leakage of body fluid can be suppressed.

  The point-like pressing part 83 is provided in the rear side pressing area R82. The rigidity of longitudinal compression area | region R81 and rear side compression area | region R82 becomes high by the dotted | punctate pressing part 83. FIG. It becomes easy for the low weight area 32 to protrude from the longitudinal pressing area R81 and the rear pressing area R82, and the fit property from the perineum to the depression between the heels is further improved, and leakage of body fluid can be suppressed. In addition, the dotted | punctate pressing part 83 should be provided in at least one part of longitudinal compression area | region R81 and at least one part of rear compression area | region R82 from a viewpoint of improving the rigidity of longitudinal compression area | region R81 and rear side compression area | region R82. Good.

The “thickness of the absorber” in this specification is measured by the following measurement method.
When the absorbent article 1 is enclosed in a package or the like, a sample that is removed from the package and left in that state in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH is used.
The measurement position is the central part in the product width direction of the absorber. When measuring, it is measured not in a state where the absorbent article is contracted but in a state where the elastic member of the absorbent article is extended. Moreover, parts other than an absorber, such as a skin surface sheet other than an absorber, and a non-skin surface sheet, are removed. A dial gauge PEACOCK manufactured by Ozaki Mfg. Co., Ltd. is used, a measuring element having a diameter of 10 mm is used, a specimen having a size of 30 mm × 30 mm is prepared, and the thickness of the specimen is measured. A measuring device adjusts so that the measurement pressure with respect to a test piece may be 3 g / cm < ² >. Here, with respect to 10 samples, the above-described measurement was performed in each state, and the average value was defined as the length.

In addition, the measurement of “weight of absorbent” in this specification is performed by the following measurement method.
When the absorbent article 1 is enclosed in a package or the like, a sample that is removed from the package and left in that state in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH is used.
In the absorbent article packaged by the packaging body, the packaging body is opened, the folded absorbent article is developed, and the thickness and area of the portion where the basis weight is measured are measured. Next, a portion for measuring the basis weight is cut out from the absorbent article, and the weight of the cut out portion is measured. Next, parts other than the absorber, such as a skin sheet and a non-skin sheet, are removed from the cut out part, and the weight of the absorber is measured. The basis weight is calculated based on the weight of the absorber and the area of the portion where the basis weight is measured.

In addition, the “length” in this specification is measured by the following measurement method.
When the absorbent article 1 is enclosed in a package or the like, a sample that is removed from the package and left in that state in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH is used. Next, using a spring measure (tape: glass fiber-containing polyvinyl chloride coating) manufactured by Shinwa Measurement Co., Ltd., the length of this state of the measurement target part is measured so as to be along the measurement target part. Here, with respect to 10 samples, the above-described measurement was performed in each state, and the average value was defined as the length.

  “Rigidity” in the present specification indicates the difficulty of deformation with respect to a force along the width direction, and the higher the rigidity, the more difficult it is to bend. The rigidity depends on the basis weight of the absorbent material constituting the absorber, and the higher the basis weight, the higher the rigidity. Therefore, the rigidity can be confirmed by visually confirming the basis weight of the absorber. The stiffness can also be measured by a Gurley stiffness value based on the measurement method of JIS L 1096.

(3) Deformation mode at the time of wearing Next, the deformation mode of the absorbent article at the time of wearing will be described in detail. As described above, the absorbent article is sandwiched between the wearer's legs when worn, and a force is applied from the outer side in the width direction to the inner side in the width direction. By applying a force from the outside in the width direction toward the inside in the width direction, the low weight area 32 of the absorbent article rises to the wearer side from the longitudinal pressing area R81 and the rear pressing area R82, and the perineum And fits into the gap between the buttock.

  Moreover, a wearer's attitude | position changes at the time of wear, and forces other than the force which goes to the inner side of the width direction are applied to an absorbent article. In a state where the wearer who wears the absorbent article lies on his back, the wearer's buttocks are deformed so as to be crushed, and the absorbent article is compressed from the rear region toward the crotch region. In a state where the wearer lies on his / her back, the deformation that causes the wearer's buttocks to be crushed is absorbed by the low-weight area 32, and the absorbent article is prevented from being deformed in an unintended manner, and absorbed by the wearer's perineum It can suppress that the clearance gap with a property article arises.

  In a state where the wearer is lying on his / her face down, the absorbent article is pressed from the crotch region side to the rear region side, and is in close contact with the perineum. In a state in which the wearer lies on his / her face down, the low weight area 32 that hits the perineum can be flexibly deformed along the body and maintain fit.

  FIG. 9 is a diagram schematically showing the deformation of the absorbent article in a state where the wearer is lying sideways. FIG. 9 schematically shows the position and deformation mode of the low weight area 32 with respect to the wearer's leg P and underwear S. FIG. 9A shows a state in which the legs P of the wearer who lies sideways overlap each other and is not displaced forward and backward. FIG. 9B shows that the legs P of the wearer are displaced forward and backward. State. As shown to Fig.9 (a), in the state which the wearer's both legs have not shifted | deviated back and forth, the force which goes to the inner side of the width direction is applied to the crotch area of an absorbent article. However, when the wearer is lying sideways, both legs P are often displaced back and forth. In general, the upper leg is positioned on the ventral side, and the lower leg is positioned on the dorsal side. When the absorbent article is sandwiched between the legs that are shifted back and forth, the absorbent article is subjected to a twisting force rather than a force parallel to the width direction. This twisting force is first applied to the high basis weight area 31 and the longitudinal pressing portion 81, and then applied to the low basis weight area 32 via the high basis weight area 31 and the longitudinal pressing portion 81. More specifically, the high weight area 31 and the longitudinal pressing part 81 are pressed by the leg located on the upper side. The low weight area 32 is located behind the high weight area 31, and the front edge of the low weight area 32 is strongly pressed through the high weight area 31 and the like, and is greatly deformed, and the rear edge of the low weight area 32 is , Pressed weakly and deformed small. At this time, the low basis weight area 32 has a low basis weight, is deformed to conform to the shape of the body, and fits the body. In addition, the low weight area 32 is deformed in a twisting direction, and is raised with respect to the perineum while suppressing positional displacement in the longitudinal direction. In addition, the low weight area 32 is adjacent to the high weight area 31, and the position in the width direction is difficult to shift. Therefore, the low basis weight area | region 32 protrudes toward the center of the width direction of a body, can fit with respect to a perineum part, and can suppress the leakage of a bodily fluid.

  Since the length in the width direction of the high weight area 31 is longer than the length in the width direction of the low weight area 32, even if the high weight area 31 is pressed inward in the width direction by the legs, it faces the excretion opening. Thus, the high weight area 31 can continue to be disposed, and the body weight can be continuously absorbed by the high weight area 31. On the other hand, since the length in the width direction of the low weight area 32 is shorter than the length in the width direction of the high weight area 31, the area raised on the wearer side becomes narrow and easily fits to the wearer's perineum. , Body fluid transmission leakage can be suppressed.

  Moreover, the force pressed by the leg is applied to the longitudinal pressing part 81 of the high weight area 31 and the crotch area S1. Since the longitudinal compression part 81 straddles the 1st side part area | region 33 and the 2nd side part area | region 34, the force by a leg is transmitted to the back side area S3 via the longitudinal compression part 81, and a rear side area | region is carried out. It is transmitted to the low weight area. A longitudinal pressing area R81 and a rear pressing area R82 are provided on both sides of the low weight area 32 in the width direction. Moreover, longitudinal compression area | region R81 and rear side compression area | region R82 are comprised easily so that it may become a surface shape. The low basis weight area 32 is raised with respect to the wearer side with the longitudinal pressing area R81 and the rear pressing area R82 as a base point.

  When comparing the front portion and the rear portion of the longitudinal compression region R81, the front portion is located on the crotch region side, so that the force by the legs is strongly applied and the force by the legs is weakly applied to the rear portion. At this time, since the length in the width direction of the longitudinal compression region R81 is longer toward the rear, the rear portion of the longitudinal compression region R81 tends to be a starting point of deformation with respect to the low weight area 32, and the rear side of the longitudinal compression region R81. The low weight area 32 between the portions is raised even by a weak force. Moreover, the rear side compression area | region R82 is arrange | positioned on both sides of the low weight area | region 32 behind the longitudinal compression area | region R81. Compared with the longitudinal pressing region R81, the force applied by the legs is weakly applied to the rear pressing region R82. At this time, since the distance W82 between the rear pressing regions R82 is shorter than the distance W81 between the longitudinal pressing regions R81, the rear pressing region R82 is easily raised by a weak force. The low weight area 32 extends in the front-rear direction, and a strong force is applied to the front portion of the low weight area, but the entire area in the longitudinal direction of the low weight area 32 is easily raised, and the entire area in the longitudinal direction of the low weight area 32 is Fits to the perineum and buttocks, and can suppress body fluid leakage.

  Since the point compression part 83 is provided in the longitudinal pressing area R81 and the rear pressing area R82, the rigidity difference between the longitudinal pressing area R81 and the low weight area 32, and the rigidity between the rear pressing area R82 and the low weight area 32. The difference becomes more prominent. When a force is applied by the legs, the low weight area 32 is easily raised from the longitudinal pressing area R81 and the rear pressing area R82. Therefore, the fitting property to the perineal part is further improved, and the leakage of body fluid can be suppressed.

(4) Other Embodiments The absorbent article extends in the width direction and has a fold line for folding the absorbent article, and the fold line may be separated from the longitudinal squeezing region. Since the longitudinal squeezing region and the fold line are separated from each other, no crease due to the fold line is formed in the longitudinal squeezing region. The shape of the longitudinal pressing area is maintained, and the low weight area tends to rise from the longitudinal pressing area. Moreover, a longitudinal pressing area | region may be spaced apart from the fold line (fold fold line) which forms the crease | fold of the direction away from a wearer among fold lines. A crease that deforms in a direction away from the wearer is not formed in the longitudinal compression region, and the longitudinal compression region easily functions as a base point for deformation of the low weight area. Therefore, the fitting property with respect to the perineal part is improved and leakage of body fluid can be suppressed.
