RR2 is located between the first rear region RR1 and the third rear region RR3.

  The disposable diaper 1 is composed of an absorbent main body 1A and an exterior body 1B, which are joined to each other by an adhesive, heat fusion, or the like.

  The absorbent main body 1A includes a top sheet 21 located on the wearer's skin contact surface side, a back sheet (not shown) located on the wearer's non-skin contact surface side, and the top sheet 21 and back sheet. And at least an absorber 30 located between them. The absorbent main body 1A is disposed across the front waistline portion S1, the back waistline portion S2, and the crotch portion S3.

  The top sheet 21 is liquid permeable and is provided on the surface side (skin contact surface side) of the absorber 30. A surface sheet is comprised by the nonwoven fabric, for example.

  The back sheet is liquid-impermeable and is provided on the back surface side (non-skin contact surface side) of the absorber 30. The back sheet 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 exterior body 1B includes a front exterior body 1BF disposed in the front waistline portion and a rear exterior body 1BR disposed in the rear waistline portion. 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 part and the back waistline part of the pants-type disposable diaper are formed with a joint part 3 in which the edges of each other are joined (see FIG. 2), and the crotch part S3 is in the front-rear direction than the joint part 3 The inner area.

  As shown in FIG. 2, the disposable diaper 1 is disposed in a pants-shaped state so as to surround the waist opening 8 disposed around the waist of the wearer and around the leg of the wearer. A pair of leg-hole openings 9 are formed (see FIG. 2).

  The exterior body 1B has the exterior surface sheet 71 (refer FIG. 1) located in a wearer's skin contact surface side, and the exterior back surface sheet 72 (refer FIG. 2) located in 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 waist support means 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 means has a function of surrounding the entire circumference of the wearer's waist and a function of supporting and holding the waist of the wearer. The waist support means includes an exterior surface sheet 71 and an exterior back sheet 72 disposed so as to surround the waist of the wearer, and 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. 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 means for supporting the wearer's leg while pushing the wearer's leg upward. The leg elastic members as the leg support means of the present embodiment are provided in the first front region RF1 and the first rear region RR1 in the waist 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 means 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 means of this invention is not limited to the said structure. The leg support means only needs to be configured to draw the leg around 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 a leg elastic member is arrange | positioned in the width direction whole region of an exterior body, it is preferable that the leg elastic member of the part which overlaps with an absorber is arrange | positioned in the non-expanded state. The non-stretched 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. FIG.2 and FIG.3 has shown typically the state visually recognized from the wearer's left side surface. FIG. 2 shows a state in which the wearer has extended his / her leg, and FIG. 3 shows a state in which the wearer has raised his / her leg to the ventral side and has taken a forward bending posture.

  In the state where the wearer's leg shown in FIG. 2 is extended, the wearer's waistline is surrounded by the front exterior body 1BF and the rear exterior body 1BR of the disposable diaper. Further, the front exterior body 1BF and the rear exterior body 1BR are in close contact with the wearer's waist by the contraction of the waist elastic member, and the waist around the wearer is supported. Moreover, since the expansion / contraction rate of the front leg elastic member is higher than the expansion / contraction rate of the rear leg elastic member, a force that presses the back side of the leg toward the abdomen acts on the wearer's leg. Therefore, it is drawn to the ventral side. Therefore, it becomes easy for the wearer to take a posture that naturally brings the leg to the ventral side.

  FIG. 3 shows a state in which the posture is changed so that the wearer moves his / her leg toward the ventral side. Since the expansion / contraction rate of the front leg elastic member is higher than the expansion / contraction rate of the rear leg elastic member, the leg elastic member presses the leg leg of the wearer toward the abdomen. 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 according to the present embodiment can realize a state of being wrapped by the mother while moving to the bed or the like by surrounding and supporting the waist of the wearer by the waist support means. . 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.

  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 leg of the wearer to the ventral side by the leg support means, 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 bending posture such that the front side of the body contracts, and once the forward bending posture is taken, the wearer can easily maintain the posture.

  The contraction stress of the second front region RF2 that constitutes the abdomen contact portion that contacts the abdomen of the wearer is lower than the expansion / contraction rate of the contraction stress of the first front region RF1 in which 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.

  Since the leg elastic member contracts so as to pull the leg around the wearer's rear waistline side toward the abdomen, the leg of the wearer can be 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, the infant can feel the state of being held by the mother in a pseudo manner by taking a forward bending posture such that the front side of the body contracts, and the infant can 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. 4 is a developed plan view of the disposable diaper 10 </ b> A according to Modification 1 in an extended state. In the exterior body of the disposable diaper 10A according to the modification, the front exterior body 1BF and the rear exterior body 1BR are integrated, and are disposed across the front waistline portion S1, the back waistline portion S2, and the crotch portion S3. .

  An end in the width direction of the crotch part S3 of the exterior body is recessed inward in the width direction, and forms a leg opening 9. The inner end portion 9I in the width direction of the leg opening 9 is located on the front side of the center CL1 in the front-rear direction of the disposable diaper. Since the inner end 9I in the width direction of the leg opening 9 is located on the front side of the center CL in the front-rear direction of the disposable diaper, the leg opening on the disposable diaper is closer to the front waist than the rear waist. Arranged biased. Therefore, the circumference | surroundings of a wearer's leg can be induced | guided | derived to the ventral side and it becomes easy for a wearer to maintain the attitude | position bent forward.

  The front end portion of the exterior body 1B is composed only of a stretchable sheet material. The front end portion of the exterior body is arranged so as to cover the belly swelled by the infant when worn. Further, when the infant moves a leg or the like, the front end of the exterior body moves in the front-rear direction along the abdomen. At this time, if the front end of the exterior body does not move smoothly along the belly bulge, the baby's belly may be tightened or the disposable diaper may be stretched against the belly. However, since the front end portion of the exterior body is composed only of a stretchable sheet material, it is arranged along the shape of the curved belly by covering the curved body by expanding and contracting in the width direction. be able to.

  Moreover, the front side edge part of the exterior body may be comprised only by the sheet material which has non-stretchability.

  Moreover, the expansion / contraction ratio of the area | region in which the front leg elastic member which concerns on the modification 1 is arrange | positioned, and the expansion / contraction ratio of the area | region in which the back leg elastic member is arrange | positioned are changing in the width direction. More specifically, the inner region RW1 and the outer region RW2 in which the region located outside the absorbent body in the width direction among the regions where the leg elastic members are arranged are equally divided in the width direction so that the expansion / contraction rate is different. It is configured.

  The expansion / contraction rate of the inner region RW1 is higher than the expansion / contraction rate of the outer region. The inner region is a region close to the wearer's leg rack. Since the expansion ratio of the inner region is relatively high, the front leg elastic member 81F and the rear leg elastic member 81R make it easy to draw the leg toward the base of the leg. Therefore, it becomes easier for the wearer to take a forward-bent posture with the legs raised to the ventral side.

  5 and 6 show an absorbent body 30 of the disposable diaper according to the second modification. FIG. 5 is a plan view of the absorbent body 30 of the disposable diaper according to the second modified example, and FIG. 6 is a diagram schematically showing the mounting state in the AA cross section shown in FIG.

  The absorbent body 30 according to the modification 2 is a pressing member that abuts on the leg around the wearer's buttocks and the wearer's buttocks and presses the wearer's leg toward the abdomen. The pressing member functions as a leg support means.

  More specifically, the absorbent body 30 as the pressing member has a recessed portion 31 that is recessed toward the non-skin contact surface in the thickness direction. The dent 31 is configured such that the bulge of the wearer's buttocks can be inserted. The depth of the recessed part 31 is changing in the front-back direction. The deepest part of the dent is located behind the center in the front-rear direction of the dent.

  When the wearer is arranged on the absorbent body configured as described above, the most swelled portion of the wearer's buttocks comes into contact with the deepest portion of the recess. The deepest part of the dent is located behind the center in the front-rear direction of the dent, and the absorber is gently inclined toward the wearer from the deepest part of the dent toward the front. Therefore, the base of the wearer's leg can be pushed up to the abdomen (upper side shown in FIG. 6) by the inclination of the absorber.

  Thus, by pushing up the base part of a wearer's leg to the abdomen side by the absorber as a press means, it is easy to maintain the forward bent posture where the infant settles down. Therefore, even when the infant is away from the mother, the infant can feel the state held by the mother, and it is easy to maintain a restful sleep of the infant.

  In addition, the absorber as a press means has a pulp and SAP which comprise the absorptive material which absorbs a bodily fluid, and is comprised. More preferably, the weight ratio of SAP to the entire absorbent material is 30% to 75%.

  7 and 8 show a disposable diaper 10B according to Modification 3. FIG. 7 is a developed plan view of a disposable diaper 10B according to Modification 3, and FIG. 8 is a cross-sectional view taken along line BB shown in FIG.

  The disposable diaper 10B according to the modified example 3 includes a pressing member 90 that abuts on the leg on the wearer's buttocks side and the wearer's buttocks and presses the wearer's leg to the abdomen. The pressing member 90 functions as a leg support means.

  The pressing member 90 of the third embodiment is formed separately from the absorber 30 and is disposed on the skin contact surface side of the absorber 30. The pressing member 90 is disposed on the skin contact surface side of the top sheet 21 and is configured to contact the wearer.
