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.
Claims12
A system comprising:
- a. an absorbent garment having an interior surface configured with a fluid porous inner surface that is configured to face a wearer, the inner surface being opposed by an fluid impervious outer surface configured to face outward from the wearer and a fluid absorbent core disposed between at least between a portion of the inner surface and outer surface,
- b. an insert capable of being fitted between a portion the wearer's body and the interior surface of the absorbent garment, the insert comprising;
- i. an upper cover that is fluid porous,
- ii. a lower cover opposing the upper cover,
- iii. a plurality of layers of an absorbent filling material consisting essentially of super absorbent polymer (SAP) particles dispersed in a network of non-hydrophilic fibers,
- iv. wherein the upper cover and lower cover are sealed about a common perimeter to contain the absorbent filling material in an interior cavity, and
- c. wherein the lower cover is an apertured film comprising an array perforations, each perforation in the array having a frustoconical shape with an open apex spaced apart from an open base, the base having a larger diameter than the apex and being closer to the absorbent filling material than the open apex.

A generally planar absorbent member comprising:
- an upper cover,
- a lower cover opposing the upper cover,
- a plurality of layers of an absorbent filling material consisting essentially of super absorbent polymer (SAP) particles dispersed in a network of non-hydrophilic fibers,
- wherein the upper cover and lower cover are sealed about a common perimeter to contain the absorbent filling material in an interior cavity, and
- the upper cover and the lower cover comprising a porous fabric,
- wherein the network of non-hydrophilic fibers expands as the SAP particles swell when absorbing fluid, wherein at least some of the SAP particles is extruded out of the network as the absorbing filling material reaches a total absorbent capacity.

An absorbent garment comprising:
- an interior surface configured with a fluid porous inner surface that is configured to face a wearer,
- a fluid impervious outer surface opposing the inner surface and configured to face outward from the wearer,
- a fluid absorbent core disposed between that has a plurality of layers in which at least some of the layers consist essentially of super absorbent polymer (SAP) particles dispersed in a network of non-hydrophilic fibers,
- wherein the network of non-hydrophilic fibers expands as the SAP particles swell when absorbing fluid, wherein at least some of the SAP particles is extruded out of the network as the absorbing filling material reaches a total absorbent capacity.
