Patent

CA 2149325

A capacity monitor for diapers (10) and the like, including super absorbent material disposed in or adja- cant to an absorbent core ( I6) is disclosed: The monitor (20) comprises an indicator (24) and a baffle (22) to pre- vent direct contact between the absorbent core and the indicator. The indicator (24) is preferably a ribbon of hot melt adhesive with a wetness indicator which changes color when exposed to liquid. The baffle (22) is a substantially water impervious sheet positioned be- tween the absorbent core ( 16) and the indicator (24) so as to prevent direct contact between them. The diaper (10) and the monitor (20) are constructed so that there is a threshold level of liquid which, when deposited in the diaper, will effect a color change in the indicator (24). A quantity of liquid which is below the threshold will not effect a color change in the indicator (24) and a quanti- ty of liquid which is above the threshold will effect a co- for change in the indicator (24).
