Abstract: An absorber 40 of a disposable diaper 10 includes a first region extending from an end at the side of the front waistline region of the absorber towards the side of the crotch region, and a second region arranged adjacent to the first region at the side of the crotch region from the first region, and having a lower bending rigidity than the first region. A boundary between the first region and the second region is arranged at the side of the front waistline region from the end at the side of the front waistline region of the leg stretch units, and is arranged at the side of the crotch region from the end at the side of the crotch region of the target unit.

Abstract: A disposable diaper (10) in this invention is comprising designs (300a, 300b) that are visually recognizable from a non-skin contact surface side S of the disposable diaper (10) is provided in a region spanning a crotch region (25) and extending to a front waistline region (20) and a rear waistline region (30). A method of arranging the design (300b) provided in a region closer to a side of the front waistline region (20) than the crotch stretching unit (200a) is configured to be different from a method of arranging the design (300a) provided in a region closer to a side of the rear waistline region (30) than the crotch stretching unit (200a).

Abstract: An absorber of a disposable diaper includes a first region extending from an end at the side of the rear waistline region of the absorber towards a side of the crotch region, and a second region arranged adjacent to the first region at the side of the crotch region from the first region, and having a lower bending rigidity than the first region. The end at the side of the rear waistline region of the leg stretch unit and the end at the side of the rear waistline region of the contracted unit in the leg side stretch unit are arranged at the side of the crotch region from the end at the side of the rear waistline region of the first region, and are also arranged at the side of the rear waistline region from the end at the side of the crotch region of the first region.

Abstract: A disposable diaper 10 has sheet-like leg hole stretch units 100 that extend in a product lengthwise direction L in an area where leg hole concave units 35 are formed and are at least partially stretchable along a product lengthwise direction L. End edges in a product widthwise direction W of the leg hole stretch units 100 meander in the product lengthwise direction L. Distances between the end edges in the product widthwise direction W of the leg hole stretch units 100 and a center line CL change from a front waistline unit 20 toward a rear waistline unit 30. Provided are a plurality of inflection points where an amount of change in the distance starts decreasing instead of increasing and a plurality of inflection points where an amount of change in the distance starts increasing instead of decreasing, respectively.

Abstract: An open-type disposable diaper includes a crotch stretch unit formed in an absorber arrangement region where an absorber is arranged in a crotch region and being stretchable in a product longitudinal direction; a pair of leg stretch units formed along a leg hole openings and being stretchable in at least the product longitudinal direction; and a waist stretch unit formed in a back waistline region and being stretchable in a product widthwise direction; the absorber core arrangement region enclosed by the crotch stretch unit, the leg stretch units, and the waist stretch unit and configuring the absorber is formed so as not to be stretched. The length of the absorber core arrangement region in the product longitudinal direction is configured to be longer than half the length of the crotch stretch unit in the product longitudinal direction.

Abstract: The disposable diaper according to the present invention includes a base sheet (12) made of nonwoven fabric and a hook sheet (110) provided with a plurality of engagement hooks. A KES bending stiffness value in a fastening tape existent region (SHS) is equal to or less than 1.64 gf·cm2/cm, the height of the engagement hook is between 60 and 200 ?m; and the color difference (?E) between the hook sheet existent region (SHS) on the inner side of a fastening tape (100) and side flaps (50) adjacent to the fastening tape (100) is 6.5 or more, when the color difference of L* is ?L*, the color difference of a* is ?a*, and the color difference of b* is ?b* according to the L*a*b* color coordinate system.

Abstract: In so far as a disposable diaper is concerned, fastening tapes each are composed of a plurality of nonwoven cloth sheets; embossment is provided at a backsheet which is provided at a most non-skin contact surface side of a respective one of nonwoven cloth sheets which correspond to a joint region in which the fastening tapes are joined at both side edges of the disposable diaper; and embossment having a same shape as or a similar shape to a shape of the embossment that is provided at the backsheet is provided at the nonwoven cloth sheet that is provided at the most non-skin contact surface side of the respective one of nonwoven cloth sheets that constitute the fastening tapes.

Abstract: A disposable diaper (10) in this invention is comprising designs (300a, 300b) that are visually recognizable from a non-skin contact surface side S of the disposable diaper (10) is provided in a region spanning a crotch region (25) and extending to a front waistline region (20) and a rear waistline region (30). A method of arranging the design (300b) provided in a region closer to a side of the front waistline region (20) than the crotch stretching unit (200a) is configured to be different from a method of arranging the design (300a) provided in a region closer to a side of the rear waistline region (30) than the crotch stretching unit (200a).
