Abstract
A disposable absorbent thong-shaped pantiliner. The pantiliner is in the form of a generally planar pad having a longitudinal central axis and a generally wedge-shaped periphery including first and second generally concave longitudinal extending sides interconnecting a top end and a bottom end. The pad includes a fluid-pervious top sheet an absorbent core and a fluid impervious back sheet that are bonded together along a first set of non-linear, parallel lines and second set of linear parallel lines. The first set of lines have portions extending generally along each side and the top and bottom end of the pad. The first set of lines also has a fourth portion extending generally along the bottom end of the pad. The second set of lines are located adjacent the bottom end of the pad and extend parallel to the longitudinal axis. The first set of parallel lines merge with the second set of parallel lines adjacent the bottom end of the pad. The parallel lines forming a barrier resistant to the egress of fluid out of the periphery of said pad and serve to channel fluid therealong to spread the fluid across the pad.
