Disposable absorbent article
View Patent ↗A disposable absorbent article has a liner, an outer cover and an absorbent body therebetween for absorbing liquid body waste penetrating the liner. A flow control layer having lateral side edges is positioned between the liner and the absorbent body, with at least a portion of each lateral side edge of the flow control layer spaced laterally inward from lateral side edges of the absorbent body. The flow control layer is at least in part liquid impermeable to retard the flow of liquid body waste penetrating the liner toward the absorbent body whereby at least a portion of the liquid body waste that penetrates the liner is directed by the flow control layer to migrate laterally outward toward the lateral side edges of the flow control layer for subsequent flow around the flow control layer toward the absorbent body.
1. A disposable absorbent article for personal wear, the disposable absorbent article having a longitudinal direction and a lateral direction, said absorbent article comprising:
a generally liquid permeable liner having a bodyfacing surface;
an outer cover;
an absorbent body disposed between the liner and the outer cover for absorbing liquid body waste and having lateral side edges; and
a flow control layer between the liner and the absorbent body, the flow control layer having lateral side edges, at least a portion of each lateral side edge of the flow control layer being spaced laterally inward from the lateral side edges of the absorbent body, the flow control layer being at least in part liquid impermeable to retard the flow of liquid body waste penetrating the liner toward the absorbent body whereby at least a portion of the liquid body waste that penetrates the liner is directed by the flow control layer to migrate laterally outward toward the lateral side edges of the flow control layer for subsequent flow around the flow control layer toward the absorbent body, the flow control layer being configured to permit at least some liquid body waste that passes through the liner to flow past the flow control layer toward the absorbent body without migrating laterally outward around the lateral side edges of the flow control layer, the flow control layer having a plurality of apertures, said apertures each being sized in the range of about 1 mm to about 10 mm.
2. A disposable absorbent article as set forth in claim 1 wherein the apertures each have a size of about 5 mm.
3. A disposable absorbent article as set forth in claim 1 wherein the flow control layer has an aperture density of less than or equal to about 14 apertures per square inch.
4. A disposable absorbent article as set forth in claim 1 wherein the flow control layer has a thickness of less than or equal to about 0.003 inches.
5. A disposable absorbent article as set forth in claim 1 wherein the flow control layer is secured to the liner.
