Absorbent article having enhanced leakage protection

摘要

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.
