Abstract
An absorbent member is intended for insertion in diapers to boost the absorptive capacity. The construction increases the flow of fluid to the diaper, yet in preferred embodiments, blocks the reflow of fluid pressed of the diaper from reaching the wearer to reduce the propensity to cause or aggravate diaper rash.
Claims16
A generally planar absorbent member comprising:
- a. an upper cover,
- b. a lower cover opposing the upper cover,
- c. at least a layer of an absorbent filling material comprising super absorbent polymer (SAP) particles disposed in a network including at least one of fibers, non-woven fibers, and structured layer of fibers,
- d. wherein the upper cover and lower cover are sealed about a common perimeter to contain the absorbent filling material in an interior cavity, and
- e. the upper cover comprising one of a non-woven and woven fabric that is porous and the lower cover comprising a flexible film adapted to transmit fluid or urine flow from the interior cavity and block fluid or urine flow into the interior cavity when the absorbent filling material still has absorbent capacity.
