Description

吸収体の非肌対向面には、点状の圧搾部と第２圧搾部42が形成されている。第２圧搾部42は、製品長手方向及び製品幅方向と交差する第１傾斜方向に延びる第１部42Aと、第１傾斜方向と交差し、かつ製品長手方向及び製品幅方向と交差する第２傾斜方向に延びる第２部42Bと、を有する。第１部及び第２部は、製品長手方向に沿って交互に連なっており、製品幅方向において間隔を空けて交互に形成されている。 A point-like compressed portion and a second compressed portion 42 are formed on the non-skin facing surface of the absorbent body. The second pressing part 42 includes a first part 42A extending in a first inclination direction intersecting the product longitudinal direction and the product width direction, a second part intersecting the first inclination direction and intersecting the product longitudinal direction and the product width direction. And a second portion 42B extending in the tilt direction. The first part and the second part are alternately arranged along the product longitudinal direction, and are alternately formed at intervals in the product width direction.

第１部の製品長手方向の長さは、第１部の製品幅方向の長さよりも長く、第２部の製品長手方向の長さは、第１部の製品幅方向の長さよりも長い。製品幅方向において隣接する第１部42Aと第２部42Bとの間の領域には、圧搾部が形成されていない。第１部42Aと第２部42Bによって囲まれた領域は、平面視にて菱形形状であり、当該領域には点状の圧搾部が形成されている。なお、吸収体の非肌対向面には、第２圧搾部42のみが形成されていてもよい。 The length of the first part in the product longitudinal direction is longer than the length of the first part in the product width direction, and the length of the second part in the product longitudinal direction is longer than the length of the first part in the product width direction. In the region between the first part 42A and the second part 42B that are adjacent in the product width direction, no pressing part is formed. The area surrounded by the first part 42A and the second part 42B has a rhombus shape in plan view, and a dotted compression part is formed in the area. In addition, only the 2nd pressing part 42 may be formed in the non-skin opposing surface of an absorber.

被覆シート40bが吸収体40の非肌対向面側で積層されるため、吸収体40の肌対向面側と非肌対向面側とを比較すると、被覆シート40bの積層による剛性差分、吸収体40の非肌対向面側の剛性が高くなる。肌対向面の剛性と非肌対向面の剛性を異ならせることができ、母親等の装着補助者がより柔らかい印象を得ることができる。 Since the covering sheet 40b is laminated on the non-skin facing surface side of the absorbent body 40, comparing the skin facing surface side and the non-skin facing surface side of the absorbent body 40, the rigidity difference due to the lamination of the covering sheet 40b, the absorbent body 40 The rigidity of the non- skin facing surface side is increased. The rigidity of the skin facing surface and the rigidity of the non-skin facing surface can be made different, and a wearing assistant such as a mother can obtain a softer impression.

実施例１に係る使い捨ておむつは、補助シート及びクロッチ伸縮部を有する。比較例１に係る使い捨ておむつは、補助シートを有し、クロッチ伸縮部を有しない。比較例２に係る使い捨ておむつは、クロッチ伸縮部を有し、補助シートを有しない。比較例３に係る使い捨ておむつは、補助シートとクロッチ伸縮部を共に有しない。なお、実施例１、及び比較例１から比較例３に係る使い捨ておむつは、補助シートとクロッチ伸縮部以外の構成は、同様である。 The disposable diaper which concerns on Example 1 has an auxiliary sheet | seat and a crotch expansion-contraction part. The disposable diaper which concerns on the comparative example 1 has an auxiliary | assistant sheet | seat, and does not have a crotch expansion-contraction part. The disposable diaper which concerns on the comparative example 2 has a crotch expansion-contraction part, and does not have an auxiliary sheet | seat. The disposable diaper according to Comparative Example 3 does not have both the auxiliary sheet and the crotch stretchable part. Note that the disposable diaper according to Example 1 and Comparative Examples 1 to 3 has the same configuration except for the auxiliary sheet and the crotch stretchable part.
