JP 2006-239162 A

  In the absorbent article described in Patent Document 1, the middle part of the front is disposed in the crotch of the wearer, that is, the area facing the vaginal opening, and the middle part of the rear is disposed in a crack in the upper buttocks behind the crotch of the wearer. Is done. Thereby, the absorber is fitted along the crack of the buttocks.

  However, in the posture in which the wearer has slept, the rear mid-high portion is disposed directly below the wearer's buttocks, that is, between the buttocks and the floor. The mid-high portion constitutes a particularly rigid region. Therefore, the wearer tends to feel uncomfortable in the sleeping posture.

  Thus, an absorbent article that does not feel uncomfortable in a sleeping position and that allows the absorbent body to easily fit along the crack is desired.

  An absorbent article (absorbent article) according to the present disclosure includes a front-rear direction (front-rear direction L) and a width direction (width direction W) orthogonal to each other, and an excretory opening contact area (excretion opening) that faces the excretion opening of the wearer. Abutting area S1), a rear area located on the rear side of the excretory opening contact area (rear side area S3), and an absorption core (absorption) disposed at least in the excretory opening abutting area and the rear side area A first low-weight area (first low-weight area) extending in the width direction between the excretory opening contact area and the rear side area. 41), a second low weight area (second low weight area 42) extending in the front-rear direction along a center line (center line CL) connecting the centers in the width direction in the rear area, and the rear area And having a front-rear pressing part (front-rear pressing part 88) extending in the front-rear direction along the center line. The absorption core of the excretory opening contact area has a basis weight higher than the basis weights of the first low weight area and the second low weight area, and the second low weight area is the first low weight area. The gist is that at least a part of the front / rear pressing part is arranged in the second low weight area.

  According to the present disclosure, it is possible to provide an absorbent article that is less likely to feel uncomfortable in a sleeping posture and that can easily fit an absorbent body along a crack.

It is a top view of an absorptive article in one embodiment. It is a top view of the absorbent article seen from the opposite side to FIG. It is sectional drawing of the absorbent article along the AA line of FIG. It is sectional drawing of the absorbent article along the BB line of FIG. It is sectional drawing of the state with which the wearer of the absorbent article shown in FIG. 1 was mounted | worn. It is sectional drawing of the state with which the wearer of the absorbent article shown in FIG. 1 was mounted | worn.

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.

The front-rear direction and the width direction orthogonal to each other;
An excretory opening contact area facing the excretion opening of the wearer;
A rear region located on the rear side of the excretory opening contact region;
An absorbent article having at least the excretory opening contact area and the absorbent core disposed in the rear side area,
The absorbent core includes a first low weight area extending in the width direction between the excretory opening contact area and the rear side area, and a center line connecting the centers in the width direction in the rear side area. A second low weight area extending in the front-rear direction, and a front-rear pressing portion extending in the front-rear direction along the center line in the rear side area,
The absorption core of the excretory opening contact area has a basis weight higher than the basis weights of the first low weight area and the second low weight area,
The second low weight area is connected to the first low weight area,
At least one part of the said front-back pressing part is an absorbent article arrange | positioned in a said 2nd low weight area.

  According to such an absorbent article, in a posture in which the wearer is sleeping, the rear side region of the absorbent article is arranged directly below the wearer's buttocks, that is, between the buttocks and the floor. Since the second low weight area formed in the rear side region has relatively low rigidity, the feeling of discomfort given to the wearer is small. Further, the absorbent material constituting the absorbent core moves between the excretory opening contact area, the right side part of the rear side area, and the left side part of the rear side area by the first low weight area and the second low weight area. It becomes difficult to do. Thereby, it can suppress that the absorption material which comprises an absorption core concentrates locally by the operation | movement during wearing. As a result, the wearer's discomfort can be alleviated while wearing the absorbent article. Therefore, the wearer is unlikely to feel uncomfortable even in the sleeping position.

  Since the second low weight area is formed in the rear side region, the center of the rear side region in the width direction is likely to protrude toward the wearer's body due to the force from the outside to the inside of the absorbent article. Moreover, the front-back compression part extended in the front-back direction is arrange | positioned in the 2nd low weight area. Therefore, the center of the rear side region in the width direction is likely to protrude toward the wearer's body with the front / rear compressed portion as an apex. Thereby, in a back side region, an absorptive article can change according to a wearer's crack shape in a sleeping posture. As a result, the wearer can obtain a comfortable fit with the absorbent article in the buttocks.

  In addition, the first low weight area suppresses the influence of the deformation of the absorbent body in the excretory opening contact area on the deformation of the absorbent body in the rear side area, and the absorbent article is formed in the excretory opening contact area and the rear side area. It is easy to deform independently. Therefore, the excretion opening | mouth contact | abutting area | region of an absorbent article can be arrange | positioned along the shape of a wearer's inseam, and the rear side area | region of an absorbent article can be arrange | positioned along the shape of a wearer's buttocks.

Such an absorbent article,
The absorbent core is disposed on both sides of the excretory opening contact area, and is disposed on both sides of the pair of first side pressing parts extending in the front-rear direction and the second low weight area in the rear side area. A pair of second side pressing parts extending in the front-rear direction,
The first side pressing part and the second side pressing part are preferably separated in the front-rear direction.

  According to such an absorbent article, since the first side pressing portion and the second side pressing portion are separated in the front-rear direction, the deformation of the absorber in the excretory opening contact region S1 The influence on deformation can be more effectively suppressed. Moreover, a pair of 2nd side pressing part extended in the front-back direction is provided in the both sides of the 2nd low weight area. Since the 2nd side pressing part has comparatively high rigidity, it serves as a modification base point of an absorption core. The second low weight area sandwiched between the pair of second side pressing parts is more likely to be raised on the wearer's body side. Thereby, it can be more familiar to the wearer's body and give a comfortable fit to the wearer.

Such an absorbent article,
The absorbent core has a third low eye area extending from the second low weight area to the outside in the width direction and having a lower weight than the weight of the absorbent core in the excretory opening contact area,
It is desirable that the second side pressing portion has a divided portion that is divided in the front-rear direction in the third low weight area.

  According to such an absorbent article, the absorbent core in the rear side region can be deformed from the third low weight area portion as a base point, so that the absorbent article can be more easily fitted along the roundness along the front-rear direction of the body. . Moreover, since the parting part of a 2nd side pressing part is provided in the 3rd low weight area, an absorption core is easy to deform | transform by the rigidity difference of the said parting part. Therefore, since the absorption core of the rear side region can be deformed with the third low weight area and the divided portion as the base points, the absorbent article can be more easily fitted along the roundness along the front-rear direction of the body.

Such an absorbent article,
It is desirable that the second side pressing portion includes a first region extending rearward from the dividing portion and a second region continuing to the rear end edge of the first region and turning back toward the front.

  According to such an absorbent article, it is possible to increase the rigidity of the absorbent core and prevent the shape of the absorbent core from being lost in the region behind the dividing portion. In particular, the vicinity of the rear end portion of the absorbent core often hits the body with a surface and is easily deformed. By forming the first region and the second region in the region behind the dividing portion corresponding to the vicinity of the rear end portion of the absorbent core, the rigidity in the vicinity of the rear end portion of the absorbent core is increased and the deformation of the core is suppressed. , Can keep along the body.

Such an absorbent article,
The absorbent core extends from the second low weight area outward in the width direction, and has a third low weight area having a lower weight than the weight of the absorbent core in the excretory opening contact area, and the third low weight area. It is desirable to have a width pressing part extending in the width direction within the region.

  According to such an absorbent article, since the absorbent core in the rear side region can be deformed from the third low weight area and the width squeezed portion as a base point, the absorbent article is more along the roundness along the front-rear direction L of the body. It becomes easy to fit. Moreover, the rigidity in the width direction of a 3rd low weight area may be improved by having a width pressing part. Depending on the wearer, the absorbent article may be used for a long time, the absorbent article may be swayed, and body fluid may leak. The leakage of the bodily fluid is particularly likely to occur in the rear side region that is likely to be deformed when walking or sleeping. Since the width squeezing part has relatively high rigidity, it can suppress unintended deformation of the absorption core in the rear side region, and can effectively prevent deformation when walking or sleeping.

Such an absorbent article,
The non-skin surface sheet located on the non-skin surface side of the absorbent core is provided with an adhesive region for stopping the absorbent article in underwear,
The adhesive area has a first adhesive area located in front of the first low weight area, and a second adhesive area located in the rear of the first low weight area,
The first adhesive region and the second adhesive region are preferably separated in the front-rear direction.

  According to such an absorbent article, since the 1st adhesion field and the 2nd adhesion field are separated, the field ahead of the 1st low weight area, and the field behind the 1st low weight area This makes it easy to achieve separate deformations and movements. The excretory opening contact area and the rear area can be more easily transformed into different shapes according to the shape of the wearer's body.

Such an absorbent article,
The excretory opening contact area has a middle-high part having a thickness greater than the thickness of the outer edge of the absorbent core,
In the cross section in the front-rear direction of the absorbent article, the rear surface of the middle-high portion absorber extending in the thickness direction from the rear edge of the middle-high portion absorber, the non-skin facing surface of the middle-high portion absorber, Is larger than the angle formed by the front surface of the middle-high absorber that extends in the thickness direction from the front edge of the middle-high absorber and the non-skin facing surface of the middle-high absorber. desirable.

  According to such an absorbent article, since the angle formed by the front surface of the mid-high part and the skin-facing surface is relatively small, the thickness of the front side of the mid-high part changes gradually, with respect to the front than the wearer's excretion opening. Can fit. On the other hand, since the angle formed by the rear surface of the mid-high portion and the non-skin facing surface is relatively large, a folding start point is easily formed on the rear surface of the mid-high portion. A deformation base point by the rear edge of the middle and high part can be provided between the excretory opening contact area and the rear side area, and the excretion opening contact area and the rear side area have different shapes according to the shape of the wearer's body. Furthermore, it can be deformed more easily.

Such an absorbent article,
The absorbent core has a central squeezing portion extending in the front-rear direction along the center line in the rear side region,
It is desirable that at least a part of the central pressing portion is disposed so as to overlap the front and rear pressing portions.

  According to such an absorbent article, by being overlapped with the front and rear compressed parts, the width direction center in the rear side region becomes thinner, and when deformed with the center of the rear side region in the width direction as a vertex, It can be fitted by the gaps in the body. Moreover, the absorber of both sides can be parted on both sides of a center pressing part and a front-and-back pressing part. By dividing the absorbent body into a plurality of parts, it is difficult to squeeze as compared with a configuration in which the absorbent body is not divided, and the absorbent body can be prevented from collapsing when used for a long time.

In addition, the front end edge of the 1st low weight area 41 mentioned later may prescribe | regulate the rear end edge of the excretion opening | mouth contact | abutting area | region S1, and the rear end edge of the 1st low weight area 41 is the front edge of the rear side area S3. May be specified.

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

  The skin sheet 10 may have 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 top sheet 11 covers the central portion of the absorber 30 in the width direction W. The topsheet 11 may extend in the front-rear direction L from the front side region S2 to the rear side region S3.

  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 side sheet 12 can be made of the same material as the top sheet 11. The side seat 12 may be disposed on the outer edge of the absorbent body 30 in the width direction W, the wing 3 and the hip flap 4. The non-skin surface sheet 20 is a liquid-impermeable sheet.

  The absorber 30 is disposed at least in the excretory opening contact area S1 and the rear side area S3. Moreover, the absorber 30 may extend from the excretory opening contact area S1 to the front side area S2. The absorber 30 includes an absorbent core 31 including an absorbent material that absorbs liquid, and a core wrap (not shown) that wraps the absorbent core 31. The core wrap should just cover the absorption core 31 at least on the skin surface side than the absorption core 31. The absorbent material constituting the absorbent core 31 can be formed from, for example, hydrophilic fibers, pulp, and superabsorbent polymer (SAP). The core wrap can be composed of, for example, a nonwoven fabric or a tissue sheet.

  As described above, the absorbent article 1 has the wing 3 and the 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 core 31 in the excretory opening contact region S1.

  The wing 3 and the hip flap 4 may be configured by stacking the side sheet 12 and the non-skin surface sheet 20. The wing 3 is configured to be folded back to the non-skin surface sheet 20 side. The wing 3 is folded back to the non-skin surface side of the crotch portion of the underwear during use.

  The hip flap 4 is located on the rear side of the wing 3 and is provided in the rear side region S3. The hip flap 4 is not folded back during use, and is disposed between the underwear and the wearer's buttocks. In the present embodiment, the hip flap 4 is not provided with an absorbent material. Alternatively, the hip flap 4 may be provided with an absorbent material.

  The “absorbing core thickness” in this specification is measured by the following measuring 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 center of the absorbent core in the product width direction. 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. Further, parts other than the absorbent core, such as a skin sheet and a non-skin sheet other than the absorbent core, 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. The measuring device is adjusted so that the measurement pressure on the specimen is 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 and density of absorbent core” 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 and density are measured are measured. Subsequently, the part which measures a fabric weight and a density is cut out from an absorbent article, and the weight of the cut-out part is measured.
Subsequently, parts other than an absorption core, such as a surface sheet and a back surface 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 absorbent body and the area of the portion where the basis weight and density are measured. The density is calculated based on the basis weight and thickness.

  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.

  Further, regarding “the angle of the middle and high parts of the absorber” to be described in detail later, the “angle of the middle and high parts of the absorber” in this specification is measured by the following measurement method. In the absorbent article packaged by the package, the package is opened, the folded absorbent article is unfolded, a photograph is taken from the side of the absorbent article, and the angles α and β shown in FIG. Measure with a protractor.

(2) Detailed structure of absorber Next, the structure of the absorber 30 is demonstrated more concretely. The absorption core 31 has the middle-high part 33 at least in the excretion opening contact area S1. The middle / high part 33 may extend from the excretory opening contact area S1 to the front side area S2. The middle / high portion 33 is disposed across the center line CL in the excretion opening contact region S1. The center line is a line connecting the centers in the width direction of the absorbent article, and is a line along the front-rear direction. The middle-high portion 33 means a region where the thickness is thicker than the thickness of the outer edge of the absorbent core. The basis weight of the absorbent material of the middle-high portion 33 may be higher than the basis weight of the absorbent core 31 in a region other than the middle-high portion 33 in the excretory opening contact region S1. Preferably, the absorption core 31 on the rear side of the first low weight area 41 is thinner than the thickness of the middle-high portion 33. More preferably, the absorption core 31 of the entire rear side region S3 is thinner than the thickness of the middle-high portion 33. Since the thickness of the middle-high part 33 is relatively thick, it is easy to fit the wearer's excretion opening. On the other hand, since the thickness of the absorption core in the rear side region is relatively thin and the rigidity in the rear side region is relatively low, it is easy to follow the movement of the wearer's leg, and the uncomfortable feeling when the leg is moved can be reduced. The rear end edge of the middle-high portion 33 is the front end edge of the first low weight area 41. A front end edge of the middle-high portion 33 is adjacent to a first side pressing portion 81 described later.

  In the cross section along the front-rear direction L of the absorbent article 1 shown in FIG. 3, the rear surface 33RS of the middle-high portion 33 extending in the thickness direction T from the rear end edge 33R of the middle-high portion 33, the non-skin facing surface of the middle-high portion 33, Is greater than the angle β formed by the front surface 33FS of the middle-high portion 33 extending in the thickness direction T from the front edge 33F of the middle-high portion 33 and the non-skin facing surface of the middle-high portion 33. The angle α is an angle formed by the rear surface 33RS of the middle-high portion 33 and the skin facing surface of the middle-high portion 33 extending forward from the rear end edge 33R of the middle-high portion 33. Further, the angle β is an angle formed by the front surface 33FS of the middle-high portion 33 and the skin facing surface of the middle-high portion 33 extending rearward from the front end edge 33F of the middle-high portion 33. Since the angle formed by the front surface of the mid-high portion and the skin-facing surface is relatively small, the thickness of the front end edge of the mid-high portion changes gradually, and the front can be fitted more forward than the wearer's excretion opening. On the other hand, since the angle on the rear end edge side of the mid-high part is relatively large, the rear end edge of the mid-high part tends to be a bending base point, and the deformation base point by the rear end edge of the mid-high part is between the excretory opening contact area and the rear side area. It can be provided and can be transformed into different shapes according to the shape of the wearer's body in the excretory opening contact area and the rear side area. In addition, since the rear edge of the middle and high portions is likely to be a bending base point, the absorbent body is deformed by the bending base point in a lying posture and can be deformed so as to be more adapted to the body.

  The absorber 30 has a first low weight area 41, a second low weight area 42, and a third low weight area 43. Here, the “low weight area” means a region composed of the absorbent core 31 having a lower basis weight than the surrounding absorbent core 31 or a region not having the absorbent core 31. As described above, the “low weight area” is a concept including an area where the weight of the absorbent core 31 is zero. In the posture in which the wearer is sleeping, the rear side area of the absorbent article is disposed directly below the wearer's buttocks, that is, between the buttocks and the floor. Since the second low weight area formed in the rear side region has relatively low rigidity, the feeling of discomfort given to the wearer is small. Further, the absorbent material constituting the absorbent core by the first low weight area and the second low weight area is the excretory opening contact area (or wing area), the right side part of the rear side area, and the left side part of the rear side area. It becomes difficult to move between. Thereby, it can suppress that the absorption material which comprises an absorption core concentrates locally by the operation | movement during wearing. As a result, the wearer's discomfort can be alleviated while wearing the absorbent article. Therefore, the wearer is unlikely to feel uncomfortable even in the sleeping position.

  The weight of the absorbent core 31 in the low weight areas 41 to 43 is preferably 60% or less of the weight of the absorbent core around the low weight areas 41 to 43 (excluding middle and high portions), and is preferably 50% or less. More preferred.

  Even when the absorbent core 31 is an area that does not have a “low weight area”, the core wrap wraps the entire absorbent core 31 across the low weight area. In this case, even if the absorption core 31 is divided into a plurality of regions, the absorber 30 is integrally formed by the core wrap.

  The first low-weight area 41, the second low-weight area 42, and the third low-weight area 43 are boundaries where the rigidity of the absorbent body 30 changes. Therefore, the first low weight area 41, the second low weight area 42, and the third low weight area 43 correspond to areas where the absorber 30 is easily deformed.

  The first low weight area 41 extends in the width direction W between the excretion opening contact area S1 and the rear side area S3. The first low weight area suppresses the influence of the deformation of the absorbent body in the excretory opening contact area on the deformation of the absorbent body in the rear area, and the absorbent article becomes independent in the excretion opening contact area and the rear area. It is easy to deform. Therefore, the excretion opening | mouth contact | abutting area | region of an absorbent article can be arrange | positioned along the shape of a wearer's inseam, and the rear side area | region of an absorbent article can be arrange | positioned along the shape of a wearer's buttocks. The first low weight area 41 is provided on the rear side of the center of the wing 3 in the front-rear direction L and on the front side of the rear edge of the absorber 30. The first low weight area 41 is provided across the rear end edge of the wing 3 in the front-rear direction L. Thereby, since the first low weight area 41 is disposed across the rear edge of the wing, which is the base end portion of the wing, in the front-rear direction, the force applied to the wing from the wearer's leg is divided at the first low weight area. And it can suppress that the said force propagates to a rear side area.

  In the present embodiment, the first low weight area 41 has a curved shape in which the center in the width direction W of the first low weight area 41 protrudes rearward. More specifically, the center of the first low weight area 41 in the width direction W is located behind the outer edge of the first low weight area 41. Thereby, the first low weight area is swollen in a convex shape toward the rear together with the underwear when lying on its back, and is pushed out in a direction away from the body. When lying on its back, the bulge of the wearer's buttocks is crushed, and the crushed portion moves to the crotch side. When the first low weight area is separated from the body, it is possible to absorb the deformation of the buttocks when lying on the back. Therefore, the excretion opening | mouth contact | abutting area | region and back side area | region arrange | positioned on both sides of the 1st low weight area are maintained in the shape which follows the roundness of a body, and the whole absorbent article is arrange | positioned along the roundness of a body.

  Preferably, the length of the first low weight area 41 in the width direction W is 25 mm or more. Thereby, it can suppress that the motion of the absorber 30 in the excretion opening | mouth contact | abutting area S1 is transmitted to the back side area S3. The first low weight area 41 may extend from one end of the absorber 30 to the other end in the width direction W. Thereby, it can suppress effectively that the motion of the absorber 30 in the excretion opening | mouth contact | abutting area | region S1 is transmitted to back side area | region S3. The outer edge of the first low weight area 41 may be located inside the outer edge of the absorbent core 31. Thereby, since the area | region where the fabric weight of an absorbent material is high is arrange | positioned at the both sides of a 1st low fabric weight area | region, the side leakage of a bodily fluid can be suppressed.

  The length of the first low weight area 41 in the front-rear direction L is preferably 10 mm or more and 50 mm or less, more preferably 10 mm or more and 30 mm or less, at the position of the center line CL of the absorbent article 1. Since the length in the front-rear direction of the first low weight area is 10 mm or more, the deformation of the excretory opening contact area and the deformation of the rear side area can be effectively divided. Further, since the length in the front-rear direction of the first low weight area is 50 mm or less, the body fluid that has flowed to the buttocks side by the rear side area can be absorbed while the body deformation is absorbed by the first low weight area. The wearer can hardly feel the anxiety that menstrual blood flows on the buttock side, and can obtain a sense of security at the time of wearing.

  The second low weight area 42 extends in the front-rear direction L along the center line CL of the absorbent article in the rear side area S3. The second low weight area 42 may extend linearly in the front-rear direction L. Since the second low weight area is formed in the rear side area, the center of the rear side area in the width direction protrudes toward the wearer's body due to the force from the outer side in the width direction toward the inner side in the width direction of the absorbent article. easy. Thereby, in a back side region, an absorptive article can change according to a wearer's crack shape in a sleeping posture. As a result, the wearer can obtain a comfortable fit with the absorbent article in the buttocks. The second low weight area 42 is preferably connected to the first low weight area 41. As a result, the deformation base point extending in the width direction by the first low weight area and the deformation base point extending in the front-rear direction by the second low weight area can be interlocked and can be deformed so as to reach a deeper crack position. Further, the middle and high portions and the convex shape formed by the second low weight area are pseudo-connected along the front-rear direction of the body, and the region capable of absorbing bodily fluids continues in the front-rear direction. Therefore, the bodily fluid adhering to a wearer's skin can be absorbed rapidly, it can suppress that a bodily fluid propagates the surface of skin, and can reduce the leak of bodily fluid.

  The rear end edge of the second low weight area 42 is located on the front side of the rear end edge of the absorbent core and on the rear side of the center of the rear side region S3 in the front-rear direction. In the cross section along the front-rear direction L of the wearer's body, a groove (crack) between the heels exists in a region from the back to the caudal bone from the back of the perineum. During use of the absorbent article, the second low weight area 42 is located in the area of the wearer's rupture. The second low weight area is applied to the area. On both sides of the second low weight area 42, areas where the weight of the absorbent core is higher than that of the second low weight area 42 and the cushioning property is high are arranged. Both sides of the second low weight area 42 are soft against the tailbone and can prevent irritation to the wearer's skin.

  The third low weight area 43 extends outward in the width direction W from the second low weight area 42 in the rear side area S3. By having the third low weight area 43, a deformation base point extending in the width direction is formed in the absorption core in the rear side area. Since the absorbent core can be deformed with the third low weight area as a base point, the absorbent article can be more easily fitted along the roundness along the front-rear direction of the body. The third low weight area 43 may be connected to the second low weight area 42. Accordingly, the deformation base point extending in the width direction by the third low weight area and the deformation base point extending in the front-rear direction by the second low weight area can be linked, and can be arranged along the roundness of the buttock.

  The outer edge of the third low weight area 43 in the width direction W is located inside the outer edge of the absorbent core 31 in the rear region S3. An absorbent material having a higher basis weight than the third low basis weight area is disposed on the outer side in the width direction than the third low basis weight area 43, and body fluid can be absorbed by the absorbent material, thereby preventing side leakage. Moreover, when the fabric weight of the outer edge of an absorption core is enough, a wearer's anxiety with respect to a leak can be wiped off. A plurality of third low weight areas 43 are provided at intervals in the front-rear direction L. Therefore, a plurality of deformation base points by the third low weight area 43 are provided at intervals in the front-rear direction L, and the absorbent core can be arranged along the roundness of the buttock.

(3) Pressing part Absorbent article 1 has a pressing part formed by compressing at least absorption core 31 in thickness direction T. The area | region where the pressing part was formed is a part with a high density compared with the area | region where the pressing part is not formed. The pressing part has the 1st side pressing part 81, the 2nd side pressing part 82, the width pressing part 83, the center pressing part 84, and the front-back pressing part 88 (refer FIG. 1).

  The 1st side pressing part 81 is provided in the excretion opening | mouth contact | abutting area S1 at least. The first side compressed portion 81 is formed by compressing the topsheet 11 and the absorbent body 30 in the thickness direction T. The 1st side pressing part 81 is arrange | positioned on both sides on both sides of the middle-high part 33, and is extended in the front-back direction L. The first side pressing part 81 defines the outer edge of the middle-high part 33.

  The first side compressed portion 81 is bent in the width direction W in the vicinity of the front end edge of the absorbent core 31 and is continuously connected in a U shape. Instead of this, the first side pressing part 81 may be provided separately on both sides in the width direction W of the middle-high part 33. That is, a pair of 1st side pressing part 81 may be provided separately with the form parted mutually. Thereby, when the force which goes to the width direction inner side from the width direction outer side is applied to an absorbent article, force becomes easy to be transmitted to the middle and high part via the 1st side squeezing part 81, and the middle and high part fits with respect to the vaginal opening. It becomes easy to let.

  The second side pressing portions 82 are provided on both sides of the second low weight area 42 in the rear side area S3. The 2nd side pressing part 82 is spaced apart from the 2nd low weight area 42, and does not inhibit convex deformation by the 2nd low weight area. The second side pressing part 82 extends along the front-rear direction L. The 1st side pressing part 81 and the 2nd side pressing part 82 are spaced apart in the front-back direction. Between the 1st side pressing part and the 2nd side pressing part, the 1st low weight area | region 41 is arrange | positioned. Since the first side compressed portion and the second side compressed portion are separated in the front-rear direction, the influence of the deformation of the absorbent body in the excretory opening contact area S1 on the deformation of the absorbent body in the rear side area is more effectively suppressed. it can. Moreover, since the 2nd side pressing part is provided in both sides on both sides of the 2nd low weight area | region 42, the 2nd low weight area pinched | interposed between a pair of 2nd side pressing parts is a wearer's body side more. It becomes easy to rise. The absorbent core is more familiar with the wearer's body and can give a comfortable fit to the wearer.

  The 2nd side pressing part 82 has the part 82a parted in the front-back direction. The divided portion is a portion where the absorber 30 and the top sheet 11 are not compressed in the thickness direction. The dividing portion 82a is provided in the third low weight area. Since the dividing part of the second side pressing part is provided in the third low weight area, the absorbent core is easily deformed due to the difference in rigidity of the dividing part. Therefore, since the absorption core of the rear side region can be deformed with the third low weight area and the divided portion as the base points, the absorbent article can be more easily fitted along the roundness along the front-rear direction of the body. In particular, when the second low weight area projects along the fissure, it may be difficult to deform the rear region along the roundness along the front-rear direction of the body. Even in this case, the rear side area can be easily deformed in accordance with the roundness along the front-rear direction L of the body by the third low weight area and the dividing portion which are the deformation base points. Thereby, it can be more familiar to the wearer's body and give a more comfortable fit to the wearer.

  The 2nd side pressing part 82 has the 1st area | region 82b extended back from the parting part 82a, and the 2nd area | region 82c which continues to the rear-end edge of the 1st area | region 82b, and turns back toward the front. The first region 82b has a curved shape extending rearward from the dividing portion 82a located rearward and extending inward in the width direction toward the rear. The second region 82c has an arc shape that folds forward. When the second side compressed portion 82 has the first region and the second region, the rigidity of the absorbent core in the region behind the divided portion can be increased. Therefore, even when an absorbent article is used for a long time, it is possible to prevent the absorbent core from being deformed or divided. Between the front edge of the first region 82b and the inner edge of the first region, the first region extends from the outer side in the width direction to the inner side in the width direction from the front to the rear. Between the inner edge of the first region 82b and the rear edge of the first region, the first region extends from the inner side in the width direction toward the inner side in the width direction from the front side toward the rear side. The area behind the third low weight area is configured to contact the tailbone. The shape of the body near the coccyx is flat compared to the rupture, but is gently rounded. Between the front edge of the first region 82b and the inner edge of the first region, the first region has a curved shape that gently extends inward in the width direction from the front toward the rear, and thus is sandwiched between the second side pressing portions. The absorbent core is gently convex with respect to the body. Therefore, the gap between the body and the absorbent article is reduced in the vicinity of the coccyx bone, and the wearer can obtain a comfortable feeling and a sense of security that is wrapped by the absorbent article.

  At least a part of the second region 82 c is disposed along the rear edge of the absorbent core 31. In the vicinity of the rear end edge of the absorbent core, it is easy for pressure to be received by the buttocks in a lying position, and twisting and rubbing are likely to occur. By forming the first region and the second region along the rear end edge of the absorbent core 31, the rigidity in the vicinity of the rear end portion of the absorbent core is increased, and even when the absorbent article is used for a long time, The absorption core can be prevented from being deformed or divided. In addition, one end (rear end edge) of the second region 82c is connected to the first region 82b, and the other end (front end edge) is not connected to the first region 82b. Since the other end of the second region 82c is separated from the first region 82b, the rear end portion of the absorbent core does not become too hard, and the wearer can continue to wear it without feeling uncomfortable. Further, in the configuration in which the left and right first areas are connected to each other, the area behind the third low weight area tends to be kept flat, which may hinder the convex deformation due to the second low weight area. is there. However, since the left and right first areas are separated from each other, the area behind the third low weight area is gently deformed into a convex shape, and the convex deformation due to the second low weight area is not hindered. The shape of the second region is not limited to the embodiment, and may be a shape extending in the front-rear direction along the outer edge of the absorbent core. Thereby, the rigidity of the outer edge can be increased in the vicinity of the rear edge and the rear edge of the absorbent core.

  The area behind the third low weight area 43 (the third low weight area located most rearward in the configuration having the plurality of third low weight areas 43) is the central compressed portion 84 and the second side compressed area. The section 82 is divided into four sections. More specifically, two of the four sections are sections surrounded by the central pressing portion 84, the third low weight area 43 located on the rear side, and the second side pressing portion, and the center. It is provided on both sides of the pressing part 84. The other two sections are provided between the second side pressing portion, the outer edge of the absorbent core, and the rear end edge of the third low weight area 43 located on the rear side. By being divided into a plurality of sections in this manner, the absorber is less likely to be squeezed compared to a configuration that cannot be divided into sections, and the collapse of the absorber when used for a long time can be suppressed. In particular, the area behind the third low weight area 43 is likely to be subjected to pressure by the buttocks, and the absorbent body is liable to sway. By dividing the region into a plurality of sections by the front / rear pressing part 88 and the second side pressing part, even if it is used for a long time and the pressure of the buttocks is repeatedly applied, the deformation of the absorbent core is suppressed, and the body Can continue to fit.

  The width pressing part 83 is formed in the third low weight area 43 in the rear side area S3. In the third low weight area having relatively low rigidity, the width squeezed portion 83 having relatively high rigidity is provided, so that a portion having high rigidity and a portion having low rigidity are alternately formed, and a plurality of bending base points are formed. Can be provided. Therefore, the absorption core can be deformed through more base points, and can be fitted to the body more. The width pressing part 83 is comprised by the aggregate | assembly of several dotted | punctate pressing parts, and is extended in the width direction. The outer edge of the width pressing part 83 is located on the inner side in the width direction than the second side pressing part 82. The dividing part 82a is arrange | positioned on the extended line extended from the width pressing part 83 along the direction where the width pressing part 83 is extended. A deformation base point extending in the width direction is formed by the width pressing portion 83 and the dividing portion 82a. By configuring the deformation base point by the divided portion having relatively low rigidity and the width squeezing portion having relatively high rigidity, a rigidity difference is generated within the deformation base point. Therefore, a plurality of bending base points can be provided, and the absorbent core can be deformed through more base points, and can be fitted to the body more.

  Moreover, an absorption core is divided into a some division via a pressing part etc. in the width direction. For example, the absorption core is divided into a plurality of sections on a virtual line that passes through the second side pressing portion and extends in the width direction. Specifically, the region on the outer side in the width direction from the second side pressing portion, the region between the second side pressing portion and the second low weight area, the outer edge of the second low weight area, and the front and rear pressing portions. The region between the outer edge of the front / rear pressing part and the region between the front / rear pressing part is partitioned by a difference in rigidity. By deforming the absorbent core in finer sections, it is possible to prevent the absorbent core from being deformed and to prevent the absorbent core from being distorted even when used for a long time.

  The center pressing part 84 is extended in the front-back direction along the center line CL in the rear side region. The center pressing part 84 is formed in the area | region containing a centerline. The absorbers on both sides can be divided across the central pressing part. By dividing the absorbent body into a plurality of parts, it is difficult to squeeze as compared with a configuration in which the absorbent body is not divided, and the absorbent body can be prevented from collapsing when used for a long time. The center pressing part 84 is comprised by the aggregate | assembly of several dotted | punctate pressing parts. The center pressing part 84 is arrange | positioned at intervals in the front-back direction L. The extension line extended from the width pressing part 83 is located in the area | region between the width pressing part adjacent to the front-back direction and the width pressing part along the direction where the width pressing part 83 extends. A deformation base point extending in the width direction is formed by the width pressing portion 83 and the region between the central pressing portions 84. The area between the central pressing parts is relatively low in rigidity and can be easily deformed with respect to the wearer's movement. By providing the deformation base point including the region with low rigidity, it becomes easier to deform following the movement of the wearer. Moreover, the irritation | stimulation to skin can be reduced by providing a deformation | transformation base point including the area | region where the said rigidity is low. At least a part of the central pressing part 84 is arranged so as to overlap the front-rear pressing part 88. A part of the central pressing part 84 is located behind the front / rear pressing part 88 and does not overlap the front / rear pressing part 88. When the front-rear pressing part 88 and the central pressing part overlap, the center in the width direction in the rear side area becomes thinner, and when the center of the rear side area in the width direction is deformed as the apex, it can be fitted by the gap of the body. .

  The front / rear pressing part 88 extends in the front / rear direction along the center line in the rear side region. The front-rear pressing part 88 is formed in the second low weight area. In the second low weight area, a region where both the front and rear pressing portions 88 and the central pressing portion 84 are formed, a region where one of the front and rear pressing portions 88 and the central pressing portion 84 is formed, and the front and rear pressing portion 88. And the area | region where both the center pressing parts 84 are not formed is provided. The front edge of the front-rear pressing part 88 may be located in the first low weight area. Since the front end edge of the front / rear squeezing portion 88 is disposed in the first low weight area having a relatively low basis weight, the front end edge of the front / rear squeezing portion is prevented from becoming too hard and softly contacts the vicinity of the delicate vaginal opening. be able to. Moreover, the front end edge of the front-rear pressing part 88 may correspond to the front end edge of the second low weight area. The second low weight area is aligned with the starting position (front edge) of the fracture, and the second low weight area and the front / rear squeezing portion 88 fit the absorbent core to the starting position of the tear, and the body fluid to the rear Can be prevented. The rear end edge of the front / rear compressed part 88 is located in front of the rear end edge of the third low weight area. The inner edge of the width pressing part 83 is arrange | positioned at the width direction both sides of the rear-end edge of the front-back pressing part 88. FIG. A difference in rigidity occurs at the rear end edge of the third low weight area behind the rear end edge of the front and rear compressed portion 88, and the inner edge of the width compressed portion is bounded on the side of the front and rear compressed portion 88. The difference in rigidity occurs. A difference in rigidity occurs between the rear end edge of the front-rear compressed portion 88 and the surrounding area, and it becomes easier to function as a deformation base point of the absorbent body. In addition, the region in front of the rear edge of the third low weight area is in contact with the rupture, and the region behind the third low weight area is in contact with the tail bone located behind the rupture. It is configured. The front / rear pressing part 88 is not disposed in the absorption core behind the rear end edge of the third low weight area 43 and is not configured to be easily deformed by the front / rear pressing part. Therefore, the durability of the area behind the third low weight area 43 is improved, and it becomes easy to continue to fit the tailbone in a flat state.

  By the 1st side pressing part 81, the 2nd side pressing part 82, the width pressing part 83, and the center pressing part 84, the surface sheet 11 and the absorber 30 are compressed by the non-skin opposing surface from the skin opposing surface side.
