  The back surface sheet 22 is liquid-impermeable and is provided on the back surface side (non-skin contact surface side) of the absorber 30. The back sheet 22 is made of, for example, a film that does not transmit liquid. In addition, the back surface sheet may be configured by a single sheet or may be configured by laminating a plurality of sheets.

  The absorber 30 has an absorbent core on which an absorbent material is laminated. The absorbent body 30 of the present embodiment is composed of an absorbent core in which pulp and SAP are mixed, and a core wrap that wraps the absorbent core. As the core wrap, for example, a tissue can be used. In addition, the absorber 30 does not need to have the core wrap which wraps an absorptive core.

  The absorbent body 30 of the present embodiment is configured to be compressible and deformable when the wearer's body pressure is applied, and functions as a support means. The absorber 30 as the support means supports the wearer's body by pressing the wearer's body by the restoring force when the support means is compressed and deformed.

  As shown in FIG. 2, the absorbent body 30 has a convex portion 31 that protrudes toward the skin contact surface at the outer end in the width direction of the absorbent body, and a concave portion 32 between the convex portions. The convex portion 31 is a portion where the thickness of the absorbent core is relatively thick, and the concave portion 32 is a portion where the thickness of the absorbent core is relatively thin. The convex portion 31 and the concave portion 32 are formed over the entire front-rear direction of the absorber 30. The convex part 31 is provided so that it may hit the swelling of a wearer's buttocks in the state in which the disposable diaper was worn. The convex part 31 is configured to compressively deform in a state where the wearer's body pressure is applied.

  In the absorbent body 30 of the present embodiment, the convex portion provided at the end in the width direction of the absorbent body abuts on the bulge of the wearer's buttocks, and the concave portion is formed between the convex portions. Not limited to. As for an absorber, the convex part and the recessed part are not formed, and the surface by the side of a skin contact surface may be a smooth surface. As such an absorber, the density of the absorbent material in the portion where the convex portion of the absorber is formed is high, the density of the portion where the concave portion of the absorber is formed is low, and the surface on the skin contact surface side is The structure which is a smooth surface can be illustrated. The absorber may have a shape that is recessed in an arc shape from the outer end in the width direction toward the center in the width direction.

  Moreover, the convex part 31 and the recessed part 32 of an absorber should just be provided in the area | region corresponding to the buttocks vicinity which a body pressure concerns most at the time of wear. Therefore, the convex portion 31 and the concave portion 32 of the absorbent body 30 may be formed only at the rear end portion of the absorbent body 30 without being formed in the entire front-rear direction of the absorbent body 30.

  The exterior body 1B includes a front exterior body 1BF disposed in the front waistline portion S1, and a rear exterior body 1BR disposed in the rear waistline portion S2. The front exterior body 1BF and the rear exterior body 1BR are separated from each other in the front-rear direction. The front exterior body 1BF and the rear exterior body 1BR may be integrated.

  The front waistline edge portion 4 located on one outer side in the width direction of the front exterior body 1BF is joined to the rear waistline edge portion 6 located on the one outer side in the width direction of the rear exterior body 1BR, and the other of the front exterior body 1BF. By disposing the front waistline edge portion 4 ′ located on the outer side in the width direction and the rear waistline edge portion 6 ′ located on the outer side in the width direction of the rear exterior body 1 BR, the disposable diaper 1 is formed in a pants shape. The front waistline portion S1 and the back waistline portion S2 of the pants-type disposable diaper are formed with joint portions (not shown) in which the edges of each other are joined. It is the area of.

The disposable diaper 1 has a waist opening (not shown) disposed around the wearer's waist and a pair of legs disposed around the wearer's leg in a pants-shaped state. A leg opening (not shown) is formed.
The exterior body 1B includes an exterior surface sheet 71 located on the skin contact surface side of the wearer and an exterior back sheet 72 located on the non-skin contact surface side. A leg elastic member 81 arranged around the leg of the wearer, a waist elastic member 82 arranged around the wearer's waist, and a fit elastic member 83 between the outer surface sheet 71 and the outer back sheet 72. Is provided. The leg elastic member 81, the waist elastic member 82, and the fit elastic member 83 are disposed along the width direction and can be expanded and contracted in the width direction.

  The front exterior body 1BF and the rear exterior body 1BR function as a waist support portion that surrounds the waist of the wearer and supports the waist while the front exterior body 1BF and the rear exterior body 1BR are joined. The waist support portion has a function of enclosing the entire circumference of the wearer's waist and a function of supporting and holding the wearer's waist. The waist support part is a fit elasticity that fits the exterior surface sheet and the like around the waist of the wearer by expanding and contracting in the width direction with the exterior surface sheet 71 and the exterior back sheet 72 arranged so as to surround the waist around the wearer It is comprised by the member 83 and the waist elastic member 82 which is arrange | positioned around a waist opening part and supports a wearer's waist.

  The waist elastic member 82 is disposed in the third front region RF3 and the third rear region RR3. The fit elastic member 83 is disposed in the third front region RF3 and the second front region RF2 in the front waistline portion, and is disposed in the third rear region RR3 and the second rear region RR2 in the rear waistline portion.

  The leg elastic member 81 includes a front leg elastic member 81F disposed in the front waistline portion S1, and a rear leg elastic member 81R disposed in the rear waistline portion S2. The leg elastic member 81 functions as a leg support part that supports the wearer's leg while pushing the wearer's leg upward. The leg elastic member as the leg support portion of the present embodiment is provided in the first front region RF1 and the first rear region RR1 in the waistline portion.

  The expansion / contraction rate of the first front region RF1 in which the front leg elastic member 81F is disposed is higher than the expansion / contraction rate of the first rear region RR1 in which the rear leg elastic member 81R is disposed. Specifically, the expansion ratio in the width direction of the first rear region RR1 is 1.6 times to 3.6 times, and the expansion rate in the width direction of the first front region RF1 is 1.8 times to 3. 8 times. Therefore, the leg opening 9 of the disposable diaper contracts on the front side rather than the rear side, and opens toward the front side. In addition, in a state where the disposable diaper is worn, the leg opening on the front waistline side contracts more than the leg opening on the rear waistline side. Therefore, the wearer's leg is drawn to the front side by the leg elastic member.

  The expansion / contraction rate of the first rear region RR1 is higher than the expansion / contraction rate of the second rear region RR2. Specifically, the expansion ratio in the width direction of the first rear region RR1 is 1.6 times to 3.6 times, and the expansion rate in the width direction of the second rear region RR2 is 1.6 times to 3. 3 times.

  The expansion / contraction rate of the first front region RF1 is higher than the expansion / contraction rate of the second front region RF2. Specifically, the expansion ratio in the width direction of the first front region RF1 is 1.8 times to 3.8 times, and the expansion rate in the width direction of the second front region RF2 is 1.5 times to 3. 2 times.

  Further, the contraction stress of the first front region RF1 in which the front leg elastic member 81F is disposed is lower than the contraction stress of the first rear region RR1 in which the rear leg elastic member 81R is disposed. Specifically, the contraction stress of the first front region RF1 is 0.2 N / 10 mm to 0.5 N / 10 mm, and the contraction stress of the first rear region RR1 is 0.3 N / 10 mm to 1.0 N / 10 mm. It is. Since the contraction stress of the first front region RF1 is lower than the contraction stress of the first rear region RR1, the first front region RF1 is easier to extend than the first rear region RR1. Therefore, it becomes easy for the wearer to draw the leg closer to the front side.

  The contraction stress of the first rear region RR1 is higher than the contraction stress of the second rear region RR2. Specifically, the contraction stress of the first rear region RR1 is 0.3 N / 10 mm to 1.0 N / 10 mm, and the contraction stress of the second rear region RR2 is 0.25 N / 10 mm to 0.9 N / 10 mm. It is.

  The contraction stress of the first front region RF1 is higher than the contraction stress of the second front region RF2. Specifically, the contraction stress of the first front region RF1 is 0.2 N / 10 mm to 0.5 N / 10 mm, and the contraction stress of the second front region RF2 is 0.1 to 0.5 N / 10 mm. .

  In addition, although the leg support part of this Embodiment is comprised by the front leg elastic member 81F higher than the expansion-contraction rate of 81R of back leg elastic members, the leg support part of this invention is not limited to the said structure. The leg support part only needs to be configured to draw the leg circumference on the wearer's rear waistline side toward the abdomen, for example, a configuration in which only the front leg elastic member is disposed and the rear leg elastic member is not disposed. The number and area of the front leg elastic member may be larger than the number and area of the rear leg elastic member.

  Moreover, although the leg elastic member 81 is arrange | positioned in the width direction whole region of the exterior body 1B, it is preferable that the leg elastic member of the part which overlaps with an absorber is arrange | positioned in the non-expanded state. A non-extendable leg elastic member is a leg elastic member arranged in a state where it does not exhibit stretchability. A leg elastic member will be in a non-extension state by fixing a leg elastic member to an exterior sheet in the state where it does not extend in the width direction, or cutting a leg elastic member.

  The second front region RF2 of the front exterior body 1BF is in contact with the wearer's abdomen and functions as an abdomen contact part. The second front region RF2 has elasticity in the width direction. The second front region RF2 only needs to be stretchable at least in the width direction, and may be stretchable in the front-rear direction L and the width direction W. For example, the second front region RF2 may be constituted by, for example, a mesh-like sheet, may be constituted by a stretchable nonwoven fabric, or may be a non-stretchable sheet in which an elastic member is stretched and fixed. It may be constituted by. The second front region RF2 of the present embodiment is configured by an exterior surface sheet 71, an exterior back sheet 72, and a fit elastic member 83 disposed between the exterior surface sheet 71 and the exterior back sheet 72. .

  As described above, the expansion / contraction rate of the second front region RF2 is lower than the expansion / contraction rate of the first front region RF1. Further, the contraction stress of the second front region RF2 is lower than the contraction stress of the first front region RF1.

  The second rear region RR2 of the rear exterior body 1BR abuts on the wearer's buttocks and functions as a buttocks abutment. The second rear region RR2 has elasticity in the width direction. The second rear region RR2 only needs to be stretchable at least in the width direction, and may be stretchable in the front-rear direction and the width direction. The second rear region RR2 may be constituted by, for example, a mesh-like sheet, may be constituted by a stretchable nonwoven fabric, or may be constituted by a non-stretchable sheet in which an elastic member is stretched and fixed. May be. The second rear region RR2 of the present embodiment is configured by the exterior topsheet 71, the exterior backsheet 72, and the fit elastic member 83 disposed between the exterior surface sheet 71 and the exterior backsheet 72. .

  As described above, the expansion / contraction rate of the second rear region RR2 is lower than the expansion / contraction rate of the first rear region RR1. Further, the contraction stress of the second rear region RR2 is lower than the contraction stress of the first rear region RR1.

  In addition, the shrinkage stress of the area | region where the elastic member is arrange | positioned can be measured by a cycle test using Shimadzu Corporation Corp .: Autograph type tensile tester, for example, type AG-1KNI.

  Specifically, it can be measured according to the following method. The distance between the left and right joints of the side part of the target disposable diaper is measured in advance in a state where the sample surface is extended to a state where no wrinkles are generated. The measured value is taken as the maximum extension sample width A. The inner distance between the left and right joints is the distance in the width direction between the joint on the front waistline edge 4 side and the joint on the front waistline edge 4 'side.

  Next, a measurement target area is cut out from one side (front side or rear side) of a diaper waistline portion as a target, and a sample is prepared. The cut out sample is set to a chuck distance of 100 mm, and the left and right latching regions are fixed to the chuck of the testing machine. Next, the sample is stretched in the direction of elongation to an elongation of 85% (85% of distance A) at a speed of 100 mm / min, and then returned to a length of 70% of elongation at a speed of 100 mm / min (of distance A 70%). The stress (N) at this time is taken as a measurement result value, and converted into a stress value per 10 mm width (N / 10 mm) based on the sample width to obtain a contraction stress value.

  The expansion / contraction rate means the degree of expansion / contraction in the contraction direction (in this embodiment, the width direction W) and is defined as follows.

Expansion rate = (length in the shrinking direction of the measurement region in the maximum stretched state) / (length in the shrinking direction of the measurement region in the natural state)
In addition, in this specification, this expansion / contraction rate shall be measured as follows, for example.

  First, when the disposable diaper is enclosed in a package or the like, the disposable diaper is removed from the package and left in that state for 60 minutes in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH. Then, the length of the measurement region (for example, the first front region RF1) is measured along the contraction direction. This length is defined as “the length of the measurement region in the natural state (for example, the first front region RF1)”.

  Second, the length in the contraction direction of the desired region in such a state (that is, the natural state), and the length in the contraction direction of the measurement region when stretched from the natural state to a state where wrinkles by the elastic member cannot be visually confirmed. Measure the thickness. This length is defined as “the length of the measurement region (for example, the first front region RF1) in the extended state”.

  Using these measurement results, the expansion / contraction rate is measured by calculating with the above formula.

(2) Wearing mode of disposable diaper Next, the wearing mode of the disposable diaper configured as described above will be described. 3 and 4 show a mounting state in a cross section based on the AA cross section shown in FIG. 3 and 4 are cross-sectional views of a portion corresponding to the wearer's buttocks. FIG. 3 shows a state before the wearer's body pressure is applied, and FIG. 4 shows a state where the wearer's body pressure is applied.

  In the state before the wearer's body pressure shown in FIG. 3 is applied, the absorbent core is not compressed and deformed, and is disposed along the shape of the wearer's buttocks. The convex portions located at both ends in the width direction of the absorbent core are in contact with the swollen portions of the wearer's buttocks.

  Next, when the wearer is laid on the bedding while lying on his / her back, the wearer's body pressure is applied to the disposable diaper, and the state shown in FIG. 4 is obtained. In the state where the body pressure shown in FIG. 4 is applied, the convex portion 31 of the absorbent body 30 is pressed by the wearer's buttocks and is compressed and deformed. When the absorber 30 is compressed and deformed, the absorber presses the wearer's body by its restoring force. The convex part 31 of the absorber 30 is in contact with the most swollen part of the collar part and the side part of the collar part, and supports the collar part.

  In addition, in the state where the disposable diaper is worn, the waist of the wearer is surrounded by the front exterior body 1BF and the rear exterior body 1BR of the disposable diaper. Further, due to the shrinkage of the waist elastic member 82, the front exterior body 1BF and the rear exterior body 1BR are in close contact with the wearer's waist, and the waist around the wearer is supported. In addition, since the first front region expansion ratio where the front leg elastic member 81F is disposed is higher than the expansion ratio of the first rear region where the rear leg elastic member 81R is disposed, The force which pushes the leg circumference to the ventral side acts. Therefore, it becomes easy for the wearer to take a posture that naturally brings the leg to the ventral side. The leg elastic member keeps pressing so as to bring the wearer's leg circumference to the ventral side in such a posture as to naturally bring the leg close to the ventral side. Therefore, once the wearer maintains a posture in which his / her leg is brought closer to the ventral side, the posture is easily maintained.

(3) Actions / Effects While the mother is hugged, the mother's waist is supported by the mother, but when the wearer tries to move to the bed, the mother's support is lost. However, the disposable diaper of this Embodiment is comprised so that an absorber may express a wearer's body support when a wearer's body pressure is applied to the absorber as a support means. Therefore, the support means supports the wearer's body due to the wearer sleeping on a bed or the like. Even when the support of the mother or the like is lost, the state wrapped in the mother can be realized in a pseudo manner. As a result of various verifications by the present applicant, it has been found that it is easy to sustain a comfortable sleep of an infant by simulating a state in which the infant is wrapped in a mother. Therefore, it becomes easy to sustain a peaceful sleep of the infant by simulating the state that the infant is wrapped in the mother.

  When the body pressure is applied to the absorber 30, the absorber is compressed and deformed, and the absorber supports the wearer's body by the restoring force of the absorber. In order to express the support of the wearer's body by the deformation of the absorbent body itself as the support means, the structure of the wearer's body can be improved with a simple structure as compared with the structure having the detection means for detecting that the body pressure has been applied. Support can be realized.

  In addition, as a result of extensive research conducted by the present applicant, it was found that infants are more likely to settle down and sleep well in a forward-bending posture (the posture where the legs are bent from the base and the legs are brought to the ventral side) so that the front side of the body contracts. . For example, in a state where the mother is held, the wearer's leg is supported by the mother and the wearer's leg is brought to the ventral side. However, when the wearer tries to move to the bed or the like, the mother's support is lost.

  The disposable diaper according to the present embodiment makes it easy to maintain a forward-bent posture by pushing the wearer's leg to the ventral side by the leg support portion, and the infant can easily maintain a calm sleep state.

  According to the disposable diaper configured in this way, even when held by the mother or away from the mother, a feeling of holding can be realized, and the infant's anxiety due to being away from the mother can be realized. Easy to suppress.

The contraction stress of the second rear region RR2 as the buttocks contact portion that contacts the wearer's buttocks is lower than the contraction stress of the first rear region RR1 in which the rear leg elastic member is disposed. Wearing a forward-bending posture that shrinks the front side of the body causes the wearer's skin to stretch and shrink, and especially the skin near the buttocks against a stretched state when taking a forward-bending posture that causes the front side of the body to shrink. Increases about 30%. At this time, since the contraction stress of the buttocks contact portion is low, it can suitably follow the expansion and contraction of the skin. Therefore, the wearer can easily take a forward-bent posture such that the front side of the body contracts, and once the forward-bend posture is taken, the posture can be easily maintained. The contraction stress of the second front region RF2 constituting the contact portion is lower than the expansion / contraction rate of the contraction stress of the first front region RF1 where the front leg elastic member is disposed. In general, an infant who is a wearer changes the swelling of the wearer's belly according to the state of eating, drinking or excretion. Since the contraction stress of the second front region RF2 in contact with the abdomen is low, the wearer's abdomen can be covered comfortably without being tightened too much.

  Moreover, since the leg elastic member contracts so that the leg circumference on the rear waist portion side of the wearer is drawn toward the abdomen, the leg of the wearer is easily drawn to the front side. In the state where the infant is held by the mother, the infant assumes a forward bending posture such that the front side of the body contracts. Therefore, by taking a forward bending posture such that the front side of the body contracts, the infant can feel the state held by the mother in a pseudo manner, and the infant can easily obtain a sense of security. Infants can easily take a forward-bent posture such that the front side of the body contracts, making it easier to settle down and sleep better.

  Since the expansion ratio of the first front region where the front leg elastic member is disposed is higher than the first rear region expansion ratio where the rear leg elastic member is disposed, the leg opening at the front waistline portion is the leg of the rear waistline portion. Shrinks more than the surrounding opening. Therefore, it is easy to draw the wearer's leg forward.

(4) Wearing article according to modification Next, a wearing article according to the modification will be described. In addition, in description of the following modified examples, the same code | symbol is attached | subjected to the same part as the disposable diaper 10 which concerns on embodiment mentioned above, and a different part is mainly demonstrated.

  FIG. 5 is an exploded plan view of the disposable diaper 10 </ b> A according to Modification 1 in an extended state. 6 is a cross-sectional view taken along line BB shown in FIG. 10 A of disposable diapers which concern on the modification 1 and embodiment differ in the expansion-contraction aspect by a leg elastic member, the presence or absence of a leg side gather, and the slit of an absorber.

  The disposable diaper which concerns on the modification 1 differs in the expansion / contraction rate of the part which overlaps with the convex part of an absorber, and the expansion / contraction rate of the part which overlaps with the recessed part of an absorber. 5 and 6 show a high stretch region R1 having a relatively high stretch rate and a low stretch region R2 having a relatively low stretch rate. The high stretchable region R1 is a region where the leg elastic member 81 having a relatively high stretch rate is disposed. The low expansion / contraction region R2 is a region where the expansion / contraction rate of the leg elastic member 81 is lower than that of the high expansion / contraction region R1, or a region where the leg elastic member is not disposed. The high stretch region R1 and the low stretch region R2 are adjacent to each other in the width direction.

  For example, when the absorbent body absorbs bodily fluid, the absorbent body moves in a direction away from the wearer due to the weight of the bodily fluid, and the disposable diaper may not be disposed at a suitable position around the wearer's leg. However, in the disposable diaper of the first modification, the stretch rate of the high stretch region R1 located in the vicinity of the wearer's leg is higher than the stretch rate of the low stretch region R2, so the high stretch region R1 is higher than the low stretch region R2. Close contact with the body. Therefore, even when the absorbent body absorbs body fluid, the absorbent body can be applied to the site intended by the wearer. Therefore, the wearer's body can be stably held, and it is easy to maintain a restful sleep of the infant.

  Moreover, the disposable diaper of the modification 1 has an upright leg side gather. The leg side gathers stand on the wearer side at the outer end in the width direction of the absorbent body and function as a leak-proof portion that prevents side leakage of body fluid. The leg side gather includes a side sheet 41, a first leak-proof elastic member 42, and a second leak-proof elastic member 43. A leg side gather is arrange | positioned so that the both ends of the width direction of an absorber may be covered, respectively. One end of the side seat 41 in the width direction (the inner end of the side seat in the width direction) is folded at a crease along the front-rear direction.
