[Problem] To provide a disposable diaper which is comfortable to wear. [Solution] This disposable diaper comprises a top sheet (), a back sheet (), an absorber () and a stretchable sheet (). The stretchable sheet () is composed by having a base material sheet () sandwich multiple elastic stretchable members () disposed therein in an extended state, said multiple elastic stretchable members () being disposed along the width direction of the disposable diaper and spaced apart at intervals in the longitudinal direction. When viewed in the width direction, the stretchable sheet () has an overlapping portion () which includes a region that overlaps with a part of the absorber (). In the overlapping portion (), the multiple elastic stretchable members () are disposed continuously along the width direction. The multiple elastic stretchable members () are not joined to the sides of the base material sheet () at the central region () of the overlapping portion (), said central region () being where part of the absorber () is overlapped, and are joined to the sides of the base material sheet () at the side regions () of the overlapping portion () which are positioned to the outside of the central region () in the width direction.

Disposable diaper

A disposable diaper is provided, including an absorber, a top sheet disposed to cover the upper surface of the absorber and at least partially formed of a liquid permeable material, a back sheet disposed to cover the lower surface of the absorber and formed of a liquid impermeable material, and a skin contact sheet disposed above the top sheet and formed with a stool passing opening capable of passing a stool therethrough. The stool passing opening is formed into such a shape that a posterior region posterior to a centerline in the anteroposterior direction of the stool passing opening is smaller in the opening area than an anterior region anterior to the centerline.

Disposable diaper having a stool passing opening

A disposable diaper is provided, including an absorber, a top sheet disposed to cover an upper surface of the absorber and at least partially formed of a liquid permeable material, and a back sheet disposed to cover a lower surface of the absorber and formed of a liquid impermeable material. The disposable diaper further includes a skin contact sheet disposed above the top sheet and formed with a stool passing opening, which is an opening capable of passing a stool therethrough, and to the both sides of the skin contact sheet, at least a pair of standing gathers are formed, which are leakage prevention walls capable of standing three-dimensionally.

A disposable pant-type diaper according to the present invention includes a front portion, a back portion, and a crotch portion which is positioned between the front and back portions, in which a waist opening and a pair of leg openings are formed by joining both longitudinal side-edge portions of the front and back portions which face each other, and stretchable elastic members are disposed along at least a part of each opening, wherein a cutout portion is formed in at least a portion of the side-edge portion of at least one of the front and back portions, and the front and back portions assume a non-joining state at the portion where the cutout portion is formed.

Disposable pant-type diaper

A disposable diaper is provided, including an absorber, a top sheet, a back sheet, and a skin contact sheet (SCS) disposed above the top sheet. The skin contact sheet is formed with a stool passing opening and a urine passing opening at a portion corresponding to a crotch part, and includes an SCS central region formed by extending a strip-shaped inter-opening region, which is sandwiched by the two openings and extends in the width direction, by half the length between the openings in the anterior direction and in the posterior direction; an SCS ventral region located at the ventral side from the SCS central region; and an SCS dorsal region located at the dorsal side from the SCS central region. A least the SCS central region has the stretching force in the width direction, and an inter-opening central region sandwiched by the two openings includes a non-stretchable region.

A disposable diaper is provided, including an absorber, a top sheet arranged to cover the top surface of the absorber, a back sheet arranged to cover the bottom surface of the absorber, and a skin-contact sheet arranged over the top sheet. The top sheet is at least partially composed of a liquid-permeable material, the back sheet is composed of a liquid-impermeable material, and the skin-contact sheet is at least partially composed of a breathable waterproof sheet and is provided with a feces-passing opening capable of allowing feces to pass therethrough.

A disposable diaper is provided which includes an absorber, a top sheet which is at least partially formed of a liquid permeable material disposed to cover an upper surface of the absorber, a back sheet formed of a liquid impermeable material disposed to cover a lower surface of the absorber, a skin contact sheet disposed above the top sheet and having a stool passing opening capable of passing a stool therethrough formed therein, and a urine/stool separation wall formed of a breathable water repellent sheet disposed in a space between the skin contact sheet and the top sheet so that the space is separated into a front body part side space and a back body part side space.
