Abstract
This invention provides a disposable urinary pad comprising a liquid-impermeable backing, an absorbent core and a liquid permeable facing adhered to the shell so as to entrap the absorbent core therebetween. The absorbent core comprises a web of absorbent fibers and superabsorbent material and has a liquid-permeable transfer layer adjacent to one surface. The absorbent core is pleated, as in an M-configuration, to form therein a center lengthwise channel. The transfer layer, after pleating of the absorbent core, extends down the sides of the core so as to provide a liquid path to the bottom of the core.
Claims17
In a disposable urinary pad having a body facing surface and a garment facing surface and comprising a liquid impermeable backing, a liquid-permeable facing, and a longitudinally extending absorbent core therebetween, the improvement wherein the absorbent core comprises:
- an absorbent medium consisting essentially of a fibrous web exhibiting wet resilience, dry resilience, and liquid absorptive properties and, adjacent to one surface of said absorbent medium, a liquid permeable transfer layer, said transfer layer exhibiting high loft, resiliency and low resistance to liquid flow and low wettability relative to said absorbent media;
- said absorbent core being further characterized by having a transverse cross-sectional configuration in the shape of a single letter M in the central area of the core, said shape resulting from a longitudinal channel being formed in the body facing surface of the core, wherein the transverse layer lines the channel and extends over the body facing surface and down the sides of the absorbent medium.
