ABSORBENT ARTICLE WITH ELEVATED SKIN-CONTACTING TOPSHEET LAYER

An absorbent article includes two planar liquid permeable topsheet layers with a first topsheet layer suspended from the longitudinal ends of the second topsheet layer. The first topsheet layer is of shorter length than the second topsheet layer such that the relaxed absorbent article includes a curvature along its length. The first topsheet layer defines a central opening and two end openings which allow for air circulation through the article and also for the second topsheet layer to be seen through the openings in the first topsheet layer. While the first topsheet layer is at least extensible, it is desirably elastic.

Fluid distribution material for absorbent articles

A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.

Absorbent article having enhanced leakage protection

An absorbent article (20;620;720;820;920;1020) capable of inhibiting leakage of a fluid insult generally extends in a plane defined by a longitudinal direction and a transverse direction. The absorbent article (20;620;720;820;920;1020) contains fluid-shrinkable members (60,61), a topsheet (11;611;711;811), and a base pad (12;812) that includes a baffle (28;828) and an absorbent core (30) positioned between the topsheet (11;611;711;811) and the baffle (28;828). The topsheet (11;611;711;811) extends in the longitudinal direction to define a distal end (153) and an opposing proximal end (152). At least a portion of the proximal end (152) remains generally unbonded to the baffle (28;828). The fluid-shrinkable members (60,61) extend in the longitudinal direction of the absorbent article (20;620;720;820;920;1020) so that at least a portion of the fluid-shrinkable members (60,61) are located adjacent to the proximal end (152) of the topsheet (11;611;711;811). Thus, when the fluid-shrinkable members (60,61) contract upon contacting a fluid insult, the proximal end (152) of the topsheet (11;611;711;811) can raise outwardly from the plane of the absorbent article (20;620;720;820;920;1020). The raised area creates a barrier to the leakage of fluids from the center of the absorbent article (20;620;720;820;920;1020) towards its end. Contraction of the fluid-shrinkable members can also cause an outer region of the topsheet (11;611;711;811) to raise outwardly from the plane of the absorbent article (20;620;720;820;920;1020) to create a barrier to the leakage of fluid from the center of the absorbent article (20;620;720;820;920;1020) towards the side edge. Because such barriers are generally created only after contact with a fluid insult, their effectiveness is not diminished through use of the article prior to the insult.

An absorbent article has a basic functionality of a skin contact sheet present and configured on the surface of an absorber such that it rises therefrom, in which no positional displacement occurs at a crotch part and which effectively avoids contact between a wearer's skin and urine/feces. The absorbent article has: a leak preventer in sheet form; an absorber arranged above the leak preventer and capable of absorbing a bodily fluid in at least one layer; a skin contact member arranged above the absorber, between a front part of the leak preventer and a rear part of the leak preventer, and that makes contact with a wearer's skin and is spaced apart from the absorber at a time of use; and a connecting unit that couples a part of the skin contact member corresponding to a crotch part of the wearer with the absorber at the time of use.
