  • Diaper having centrally-located chromatographic layer with peripherally-located wetness indicator
    Patent number: 6515194
    Abstract: A diaper includes a diaper substrate having a peripheral edge and a centrally-located region where fluid from a user will make initial contact therewith, a fluid transport layer disposed with the diaper substrate and having a peripheral edge and a centrally-located portion disposed at the centrally-located region of the diaper substrate, and a wetness indicator on the peripheral edge of the transport layer and exposed and extending along at least a portion of the peripheral edge of the diaper substrate. The transport layer made of a fluid-permeable chromatographic medium draws fluid via capillary action from its centrally-located portion at the centrally-located region of the diaper substrate toward its peripheral edge and into contact with the wetness indicator. The wetness indicator is a material capable of eliciting a visible response to the presence of fluid.
