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).
Claims14
A disposable diaper, comprising:
- a front waistline region;
- a rear waistline region;
- a crotch region positioned between the front waistline region and the rear waistline region;
- a pair of leg hole openings;
- an absorber spanning the crotch region and extending to the front waistline region and the rear waistline region;
- a product longitudinal direction extending from the front waistline region to the rear waistline region;
- a product widthwise direction perpendicular to the product longitudinal direction;
- and
- a stretchable crotch stretching unit disposed in a region in which the absorber is arranged in the crotch region, wherein
- the crotch stretching unit has a front end closer to the front waistline region, and a rear end closer to the rear waistline region,
- designs that are visually recognizable from a non-skin contact surface side of the disposable diaper span the crotch region and extend to the front waistline region and the rear waistline region,
- the design provided closer to the front waistline region is arranged differently from the design provided closer to the rear waistline region to visually indicate the front end of the crotch stretching unit or the rear end of the crotch stretching unit,
- the crotch stretching unit overlaps an area of the absorber in a product thickness direction crossing the product longitudinal direction and the product width direction, and
- the crotch stretching unit is configured to contract in the product widthwise direction to cause the area of the absorber to be constricted.
