And a liquid-permeable core wrap sheet 59 formed of tissue paper or the like.

<Size adjustment means>
4 and 5, the size adjusting means 28 is formed from a known fiber nonwoven fabric, for example, a spunbond fiber nonwoven fabric having a mass of about 20-100 g / m ² , preferably about 40-80 g / m ² . the fastening band 26, a known non-woven fabric, for example, the mass of about 30 to 80 g / ^{m 2,} preferably, formed from about 40 to 60 g / span ^{m 2} bond fibrous nonwoven fabric or SMS nonwoven fabric, fastening bands And a loop-shaped guide member 27 through which 26 is inserted. The fastening band 26 has an inner surface facing the outer surface of the diaper 10 and an outer surface opposite to the inner surface, and an outer edge 26a and an inner edge 26b facing each other in the direction of the horizontal axis X, and both side edges extending in the waistline direction. Is a rectangle defined by The fastening band 26 includes a proximal portion 74 fixed via side seams 22 at both side edges of the front waist region 13, and a distal portion 75 located on the opposite side of the proximal portion 74 in the length direction thereof. And a length direction extending from the proximal portion 74 to the distal portion 75 and a width direction orthogonal to the length direction. The distal portion 75 has a rectangular fastening region 76 located on the outer surface thereof, and a gripping portion 77 extending from the fastening region 76 toward the inner edge side.

  The fastening region 76 is formed from a hook element of a mechanical fastener, and can be fastened to the outer layer sheets 30 and 39 made of a fiber nonwoven fabric that form the outer surfaces of the front and rear waist regions 13 and 14. On the other hand, when the outer surfaces of the front and rear waist regions 13 and 14 are formed from a plastic film, the fastening region 76 is formed from a pressure-sensitive adhesive. The fastening region 76 is located on the inner side in the direction of the horizontal axis X than the guide member 27, and is folded and fastened to a portion between the proximal portion 74 and the distal portion 75. Thus, since the fastening area 76 formed from the hook element or the like is not exposed in the state where the size adjusting means 28 is not used, there is no possibility that the wearer's body touches it and gives a stimulus. . In order to achieve such an effect, the fastening area 76 itself is not folded, but a gripping portion 77 having a length dimension larger than the length dimension of the fastening area 76 is provided, and the gripping section 77 is folded and secured. It may be overlaid on area 76.

  The guide member 27 is fixed to the outer surface of the outer layer sheet 30 that is spaced apart in the direction of the longitudinal axis Y, and is opposed to the both sides fixing portion 79 in the width direction of the fastening band 26 and the outer layer sheet positioned between the both side fixing portions 79. And a covering portion 80 that covers the fastening band 26 in the width direction and covers a part thereof. The width dimension W1 (dimension in the direction of the vertical axis Y) of the fastening band 26 is about 15 to 40 mm, and the length dimension L1 (dimension in the direction of the horizontal axis X) is about 120 to 240 mm. The width dimension W2 (dimension in the direction of the horizontal axis X) of the guide member 27 is about 10 to 30 mm, and the length dimension (dimension in the direction of the vertical axis Y) L2 is about 25 to 60 mm. “The guide member 82 straddles the fastening band 26 in the width direction” means that the folded guide edge 80a extends in parallel with the width direction, and does not run in parallel with the width direction. This includes a case where the two sides of the band 26 intersect with each other at an angle.

  If the leg opening edge of the diaper 10 has a relatively large peripheral dimension relative to the wearer's thigh 72, that is, a slight separation between the upper edge 23 of the leg opening edge and the thigh 72. When the part (gap) 81 is formed, the leg opening edge portion does not fit the wearer's thigh 72 and causes leakage of excrement. In particular, such a situation is likely to occur in adult diapers having different sizes of the wearer's body. In such a case, the wearer pulls the fastening band 26 of the size adjusting means 28 inward in the direction of the horizontal axis X according to the following procedure, and then reverses the folded band 26 along the guide member 27 to return the front waist region 13 and the rear The leg opening edge is fitted to the wearer's thigh 72 by being fastened to the clothing-facing surface of the waist region 14 or the outer surface of the fastening band 26, thereby forming a spaced-apart portion 81 that causes excrement leakage. Can be prevented.

<First step>
Referring to FIG. 6, first, the wearer grasps the gripping portion 77 of the fastening band 26 with one hand and pulls it inward in the direction of the horizontal axis X to bring the proximal portion 74 to the wearer's thigh 72. Pulling closer to each other, that is, pulling in the direction of arrow F, adjusts the amount (dimension) of the separated portion R positioned between the side seam 22 and the guide member 27. A plurality of gathers 82 are formed in the vicinity of the guide member 27 according to the amount of dragging.

<Second step>
Referring to FIG. 7, next, the garment of the front waist region 13 is folded back along the inner edge (folded guide edge) 80 a of the guide member 27 while being pulled and pulled in the direction of the arrow P. It is fixed to the opposite surface via a fixing region 76. The direction of folding back is not limited to the diagonally upper direction, but may be reversed 180 degrees to secure the fastening region 76 on the outer surface of the guide member 27, or may be reversed diagonally and secured to the clothing facing surface of the diaper 10. May be. By fastening the fastening area 76, the dimension of the separation region R is maintained in a reduced state, and the diaper 10 is fitted to the wearer's body. Thus, in order to maintain the state of the 1st step, it is not necessary to hold down front waist region 13 with the other hand, and an operator continues stop band 26 in order of the 1st step and the 2nd step. It can be operated relatively easily with one hand.

  When the fastening band 26 is not previously covered with the guide member 27, first, the user holds the guide member 27 with the other hand while holding the holding portion 77 of the fastening band 26 with one hand. When the operation of inserting the fastening band 26 into the covering portion 80 is necessary, as described above, a part of the fastening band 26 has already been inserted into the covering portion 80 of the guide member 27 in the state before the diaper 10 is worn. Then, since a part of the distal portion 75 extends inward in the direction of the horizontal axis X from the folded guide edge portion 80a, the operator grasps the gripping portion 77 and keeps the first and second from the state as it is. The fastening band 26 can be operated in the order of steps, and the size can be adjusted with one hand throughout.

  In the present embodiment, the proximal portion 74 of the fastening band 26 that constitutes the size adjusting means 28 and the fixing portion 79 of the guide member 27 are located in the same waist region 13, 14. Therefore, when the one side edge part of the waist region is drawn toward the inside of the diaper 10, the leg opening is directed to the waist region side. When the size adjusting means 28 is located in the front waist region 13, for example, when the wearer is lying in a stooped state or in a state where the back and both knees are bent and rounded, the front waist region 13 of the diaper 10. Although there is a possibility that the side may be loosened and separated from the wearer's body, the wearer does not loosen the front waist region 13 side of the diaper 10 by adjusting the size by the size adjusting means 28 even in such a posture or body shape. Can be fitted to the body. Therefore, it can be said that the size adjusting means 28 of the present invention is capable of adjusting the size according to the wearer's body shape as well as simply adjusting the size of the waistline and legs.

  When the size adjustment means 28 is located in the back waist region 14, the side edge part of the diaper 10 can be drawn back, and, thereby, the whole diaper 10 can be drawn to a wearer's back side. For example, when the wearer is an elderly person and the buttocks are thin and thin, the thickness of the buttocks is small with respect to the entire waist circumference, and the portion facing the buttocks on the rear waist region 14 side is slack. However, by arranging the size adjusting means 28 in the rear waist region 14, the diaper 10 can be stably fitted to the wearer's body even in such a body shape. Therefore, it can be said that the size adjusting means 28 of the present invention is capable of adjusting the size according to the wearer's body shape as well as simply adjusting the size of the waistline and legs. Thus, even when the size adjusting means 28 is disposed in any of the front and rear waist regions 13, 14, the waist region and the leg opening edge can be drawn in accordance with the posture and body shape of the wearer, Further, the same effect can be obtained by fixing the guide member 27 fixed to the front waist region 13 to the front side of the crotch region 15 or fixing the guide member 27 fixed to the rear waist region 14 to the rear side of the crotch region 15. Can be obtained. That is, the proximal portion 74 of the fastening belt 26 and the fixing portion 79 of the guide member 27 may be located in either the front region 20A or the rear region 20B of the diaper 10. On the other hand, when the proximal portion 74 of the fastening band 26 and the fixing portion 79 of the guide member 27 are located in different waist regions, the size is adjusted by simply dragging both side portions of the front and rear waist regions. The size cannot be adjusted in accordance with the wearer's body shape.

  The fixing portion 79 of the guide member 27 is located outside the outer edge of the absorber 52 in the direction of the horizontal axis X. In the second step, when the fastening band 26 is reversed and folded back along the guide edge 80a and pulled up, the separated portion between the relatively rigid absorber 52 and the fixing portion 79 is pulled. Where there is a risk of leaving the body, it is possible to fit the separated portion to the wearer's body by providing an elastic region in the portion. That is, by providing an elastic region at a position overlapping the fixed portion 79 of the guide member 27 and / or inside the direction of the horizontal axis X from the fixed portion 79 of the guide member 27, the elastic region is expanded when adjusting the size. Accordingly, the fastening band 26 can be pulled inward more easily, and after the size adjustment, the diaper 10 is fitted to the wearer's body while the size is adjusted by contraction of the elastic region. . In the present embodiment, in particular, the high elastic region 34 in which the third front waist elastic body 33 having a higher elastic force than the other regions of the front waist region 13 is disposed is located in the separated portion. Therefore, this effect can be exhibited more.

<Joint strength of guide member>
In the second step, when the fastening band 26 is folded back with the folded guide edge 80a of the guide member 27 as a starting point, the guide member 27 is prevented from being released from being fastened to the front waist region 13. The fixing portion 79 needs to have a required joint strength. Specifically, the joint strength is preferably about 7 to 100 N, more preferably about 15 to 70 N. When the joining strength is 7 N or less, there is a possibility that the fixing portion 79 of the guide member 27 may be peeled off from the front waist region 13 when the fastening band 26 is turned back via the turn guide edge 80a. In the case of 100N or more, the flexibility as the fiber nonwoven fabric of the both-side fixing part 79 is impaired, and the rigidity becomes relatively high, which may give the wearer's skin a feeling of strangeness or irritation.

<Fastening strength of fastening band>
The fastening area 76 of the fastening band 26 is required when it is fastened to the front waist region 13 so that the tensioned state of the fastening band 26 that is dimensionally adjusted during wearing of the diaper 10 is not released. It is necessary to have a fastening strength of. Specifically, the fastening strength is preferably about 3 to 75N, more preferably 5 to 60N. If the fastening strength is 3N or less, the fastening of the fastening band 26 may be released during wearing. On the other hand, if the fastening strength is 75N or more, the dimension adjustment is performed again. Excessive force is required when releasing the fastening, and it may be difficult to operate with one hand.

<Measuring method of bonding strength of guide member>
8, the joint strength of the guide member 27 was measured by the following method using a tensile tester (Autograph Tester (AG-X10plus) manufactured by Shimadzu Corporation). The front waist panel 17 is cut to a size of 25 mm inward in the direction of the horizontal axis X from the folded guide edge 80a and 50 mm outward (total of 75 mm) to form a sample 83, and the back of the sample (skin facing surface of the diaper 10) is stainless steel A white cloth 86 (25 mm × 200 mm) having a tear strength higher than the joining strength of the guide member 27 was inserted into the guide member 27 from the guide edge portion 80a. 86 is attached to the movable chuck 87, and the side edge portion of the sample 83 opposite thereto is attached to the fixed chuck 88. Pulling the Q direction at a speed 100 mm / min tensile click 87, the tensile strength determined, such five measurements performed (N = 5), and the average was taken as the bonding strength.

<Measurement method of fastening strength of fastening band>
The fastening strength was measured by the following method using a tensile tester (Autograph Tester (AG-X10plus) manufactured by Shimadzu Corporation) First, a fastening band 26 was cut from an arbitrary diaper 10 and sample 1 Then, as an object to be engaged with the sample 1, a part of the outer layer sheet of the diaper 10 is cut out to be the sample 2. Next, the fastening area 76 of the fastening band 26 in the sample 1 is set to the opposite surface of the sample 2 (the diaper 10). Both samples are stacked so that they face each other on the clothing facing surface side.A 700 band-weight roller (diameter: about 85 mm, width: about 45 mm) is fastened at a speed of 300 mm / min from above the stacked samples. The fastening area 76 was crimped to the opposite surface of the sample 2 by reciprocating along the engagement / disengagement direction of the sample 2. Set on both crimped sample tensile testers and pull Pulled at a rate of about 100 mm / min to measure the engagement force of both samples were the engaging strength of the fastening band 26.

Referring to FIG. 9, it is a front view similar to FIG. 6 showing an example of a modification of the diaper 10 in the first embodiment, and a lubricant such as silicon oil is applied to the outer surface of the fastening band 26. Yes, a plastic film (friction resistance reducing means) 84 having a mass of about 15 to 25 g / m ² is attached. For the fastening band 26, instead of sticking such a film, a material capable of reducing the frictional resistance against the guide member 27, for example, a plastic film mainly composed of polyethylene or polypropylene, A plastic film, a fiber nonwoven fabric, or the like that has been subjected to fluororesin processing can be attached.
