Abstract: [Problem] To provide a disposable diaper which is comfortable to wear. [Solution] This disposable diaper comprises a top sheet (1), a back sheet (2), an absorber (3) and a stretchable sheet (4). The stretchable sheet (4) is composed by having a base material sheet (41) sandwich multiple elastic stretchable members (42) disposed therein in an extended state, said multiple elastic stretchable members (42) 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 (4) has an overlapping portion (43) which includes a region that overlaps with a part of the absorber (3). In the overlapping portion (43), the multiple elastic stretchable members (42) are disposed continuously along the width direction.

Abstract: An absorbent article has a liquid-permeable front surface sheet, a liquid-impermeable back surface sheet, and an absorber disposed between the front surface sheet and the back surface sheet. The absorbent article includes a groove portion entirely or partly composed of a recessed portion, the recessed portion being formed on the front surface sheet side of the absorbent article by integrally joining the front surface sheet and the absorber together, and a flat portion enclosed by the groove portion. A diameter of a maximum inscribed circle inscribed in the flat portion is at least five times and at most 20 times as large as a width of the groove portion along a radial direction of the maximum inscribed circle.

Abstract: An absorbent article is provided, which is resistant to deformation and can maintain the breathability even under the force applied by various body movements, such as load of sitting. An absorbent article of the present invention includes a liquid permeable top surface sheet, a liquid impermeable back surface sheet, and an absorber disposed between the top surface sheet and the back surface sheet. Grooves extend on the top surface sheet side, and in each of the grooves, a plurality of recess portions formed by integrally joining the top surface sheet and the absorber are arranged. Each of the recess portions has a sidewall and a bottom.

Abstract: An absorbent article according to the present invention having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the top sheet and the back sheet includes a first recessed portion configured in a top surface of the absorber facing the top sheet and extending along a first direction and a second recessed portion configured in the top surface of the absorber facing the top sheet so as to intersect the first recessed portion, the second recessed portion extending along a second direction different from the first direction. The first recessed portion and the second recessed portion each have a first area having a shallow depth from the top surface of the absorber to a bottom surface of the first area and a second area having a deeper depth than the first area.

Abstract: The present invention addresses the problem of improving quick-drying properties of a top sheet at a part that often contacts with the skin of a wearer. A top sheet (10) for absorbent articles comprises an upper layer sheet (11), a lower layer sheet (12), multiple bonded parts (40) at which the sheets (11, 12) are bonded to each other, and multiple unbonded parts (50) which are surrounded by the multiple bonded parts (40). Each of the unbonded parts (50) has a larger area (51) that has a relatively large area and a smaller area (52) that has a relatively small area and is extended in one direction from the larger area (51). The upper layer sheet (11) is protruded convexly in the larger areas (51) and the smaller areas (52).

Abstract: To maintain, in a wide state, the spaces in a ventilation channel formed when a waist expansion member contracts. This disposable diaper has formed therein, on one or both of a front part (1) and a rear part (2), a cushion part (40). The cushion part (40) includes: an inner sheet (41); an outer sheet (42); one or a plurality of waist expansion members (43); and a cushion forming sheet (44). In a state where the waist expansion member (43) is stretched in the width direction, the member is secured between the inner sheet (41) and the outer sheet (42). The cushion forming sheet (44) overlaps one or both of the inner sheet (41) and the outer sheet (42), and is joined thereto so that in the width direction joining portions (51) and non-joining portions (52) are alternatingly continuous. The joining portions (51) are formed by joining-lines (53) which are straight and extend in the longitudinal direction and at least two columns of which are side by side.

Abstract: To improve the ventilation properties of a sheet used in a flute structure. This disposable diaper has formed therein, on at least one of a front part and a rear part, a cushion part (40).
