Embodiment Construction

[0042] One example will be described about the disposable diaper of the first aspect.

[0043] figure 1 It is a perspective view which shows the wearing state of the diaper 210. figure 2 It is a partially cutaway developed plan view when the diaper 210 is peeled back and forth at the joint portion 222 and stretched in the longitudinal direction X and the transverse direction Y, image 3 yes figure 2 Sectional view of III-III. Figure 4 means removed figure 2 A partial cutaway view of the absorbent backsheet 212 in the rear state.

[0044] Such as figure 1 As shown, the diaper 210 includes an annular elastic waist panel 211, an absorbent backsheet 212 mounted on the skin-contacting side of the annular elastic waist panel 211, a front waist region 213, a rear waist region 214, and a front and rear waist region 213, A crotch region 215 extending in the longitudinal direction X between 214 .

[0045] The elastic waist panel 211 is composed of a rectangular front waist ...

Abstract

The present invention aims to provide a wearing article improved to prevent an undesirable step from being formed due to downward displacement of a front end flap of an absorbent chassis during use of the diaper, to prevent body waste from leaking out and to assure a good appearance. At least the front waist region 213 of the front and rear waist regions 213, 214 includes elasticized regions 225, 226, 227 extending at least in the transverse direction Y, wherein the elasticized regions 225, 226, 227 comprise a first elasticized region 225 defined between a waist-opening' peripheral edge 223a and the vicinity of a front end flap of the absorbent chassis 212 so as to extend in the transverse direction Y, a second elasticized regions 226 defined adjacent the first elasticized region 225 so as to extend in the transverse direction Y and a pair of third elasticized regions 227 defined adjacent the second elasticized region 226 and spaced from and opposed to in the transverse direction Y on both sides of a non-elasticized region 228A formed in a transverse middle of the front waist region 213 wherein the second elasticized region 226 extends across the front flap of the absorbent chassis 212.

Description

technical field [0001] The present invention relates to a disposable diaper, in particular to a disposable diaper with better fit and satisfactory appearance. Background technique [0002] Disposable diapers are generally known in which a plurality of waist elastic members extending in the direction of the waist are provided in the front and rear waist regions in order to ensure a close fit to the wearer's body. For example, the following disposable diaper 110 is disclosed in Patent Document 1: Figure 11 As shown in (a) and (b), the disposable diaper 110 has front and rear waist regions and a crotch region, an absorbent backsheet 112 disposed on the inner surface of the waist member 111, and a waist opening edge 116a spaced longitudinally in the figure. A plurality of waist elastic elements 126 extending in predetermined dimensions, the waist elastic elements extending from the side edges of the front and rear waist regions to the side edges of the absorbent backsheet 112 ....
