An absorbent article such as a diaper comprises a topsheet, a backsheet and an absorbent core. The absorbent layer comprises at least a longitudinally-extending central portion, and a first and second side portions disposed transversally outward of the central portion. The absorbent core further comprises first and second folding guides between the central portion and the side portions. Each side portion comprises a plurality of winglets, each winglet having a proximal side relative to a folding guide and extending outward from this proximal side, and wherein neighboring winglets are separated by a gap between their neighboring sides. The central portion and the side portions form a three-dimensional basin when the absorbent core is folded along the folding guides. The article further may comprise at least one liquid management layer substantially free of superabsorbent polymer between the topsheet and the absorbent core. The absorbent core may be substantially free of cellulose fibers.

The present invention provides a disposable wearing article which prevents a position shift of a front waist region without a part of a front waist region receding in a concave portion of the abdomen of the wearer. A plurality of linear front waist elastics contractible in a lateral direction is disposed in a front waist region of a disposable wearing article. The front waist elastics have (include) a first elastic positioned adjacent to an outer side of a front-end edge of a liquid absorbent core in a vertical direction, a second elastic positioned adjacent to an inner side of the front-end edge in the vertical direction, and a third elastic positioned adjacent to an inner side of the second elastic in the vertical direction. A contractile force of the first elastic and the second elastic is weaker than a contractile force of the third elastic.

A dorsal side barrier is configured so as to stand up unintentionally when a diaper is used. This problem is solved by an underpants-type disposable diaper characterized by being provided with the dorsal side barrier which is unfolded so as to spread in a natural length state and which is turned up automatically when the diaper is stretched.

An absorbent article such as a diaper comprises a topsheet, a backsheet and an absorbent core. The absorbent layer comprises at least a longitudinally-extending central portion, and a first and second side portions disposed transversally outward of the central portion. The absorbent core further comprises first and second curved folding guides between the central portion and the side portions. Each side portion comprises a plurality of winglets, each winglet having a proximal side relative to a folding guide and extending outward from this proximal side, and wherein neighboring winglets are separated by a gap between their neighboring sides. The central portion and the side portions form a three-dimensional basin when the absorbent core is folded along the folding guides. The absorbent core is substantially free of cellulose fibers. The article further may comprise at least one liquid management layer substantially free of superabsorbent polymer between the topsheet and the absorbent core.

An absorbent article having an elastic film stretchable region in which a stretch rate changes depending on the part, and a method of manufacturing the same. The above problem is solved when a stretchable region being stretchable at least in a width direction is included in a lower-torso region having a waist portion of an outer body of a front body and an outer body of a back body, and in the stretchable region, in a state in which an elastic film is stretched in a stretching and contracting direction at a stretch rate continuously increasing from a crotch side toward a waist opening side, a first sheet layer and a second sheet layer are joined.

An elastic sheet for an absorbent article includes a first fibrous layer disposed on a first surface of the elastic sheet, a second fibrous layer disposed on a second surface of the elastic sheet opposite to the first surface, and contractible elastic members secured between the first fibrous layer and the second fibrous layer. The first fibrous layer and the second fibrous layer each include continuous fibers of thermoplastic and gathers formed between adjacent ones of the elastic members. The gathers are disposed in an intersecting direction intersecting with a direction in which the elastic members extend. An average flexural rigidity value of the first fibrous layer and the second fibrous layer in accordance with a KES method is 0.003510.sup.4 to 0.02210.sup.4 (N.Math.m.sup.2/m). A thickness under a compression load to the gathers in accordance with the KES method is 0.22 to 1.5 mm.

A member that exhibits a complicated appearance without monotonous contraction wrinkles and has excellent appeal to consumers when the member is applied to an absorbent article. A third joined portion row is formed between a first joined portion row A1 and a second joined portion row adjacent to each other, and an interval of at least a part of the third joined portion row in the alignment direction is longer than an interval S1 of the first joined portion row and the interval of the second joined portion row in the alignment direction.

The rising gather of a disposable diaper includes: a main unit portion having a first portion extending from both sides of an inner member toward the center in the width direction and a second portion extending outward in the width direction. Front and back fallen portions are formed by fixing front and back end portions in the main unit portion to the inner member. The front and back fallen portions have a protruding portion in which the second portion protrudes 5 to 40 mm outward in the width direction than a side edge of the first portion. The protruding portion of the front fallen portion has a protruding fixing portion fixed to the front outer member overlapping with a back surface side thereof. The protruding portion of the back fallen portion has a protruding fixing portion fixed to the back outer member overlapping with a back surface side thereof.

The present invention relates to a folded side-leakage-proof arc-shaped elastic sanitary product wainscot and a production line therefor. After two sides of an elastic membrane under a tensile state are compounded with nonwoven fabric strips by hot pressing respectively, the elastic membrane rebounds and resets to impel the nonwoven fabric strips located on two sides of the elastic membrane to form a folded side-leakage-proof side wall. The elastic membrane is in the shape of a concave arc. The present invention has the following advantages: 1, the nonwoven fabric strips may be compounded with two sides of the elastic air-permeable membrane without a hot melt adhesive so as to ensure that the air permeability of the elastic air-permeable membrane and the nonwoven fabric strips is not affected by the hot melt adhesive; and 2, after two sides of the elastic air-permeable membrane under a tensile state are compounded with the nonwoven fabric strips, the elastic air-permeable membrane rebounds to impel the nonwoven fabric strips to form a required elastic folded side-leakage-proof side wall with the rebound and reset of the elastic air-permeable membrane. This side wall not only has a function of preventing liquid from flowing, but also greatly reduces a contact area between a sanitary napkin or a panty-shape diaper and a human body, such that the comfort level of the human body is greatly improved.

An absorbent article can include a bodyside liner that provides a barrier region. The barrier region can be a central portion of the bodyside liner not coupled to the absorbent body. The barrier region can include a first longitudinal side edge and a second longitudinal side edge. The first longitudinal side edge can be coupled to the projection portion of the first containment flap. The second longitudinal side edge can be coupled to the projection portion of the second containment flap. When the absorbent article is in the relaxed configuration and the projection portion of the first containment flap and the projection portion of the second containment flap extend away from the absorbent body, the central portion of the bodyside liner extends away from absorbent body.
