ABSTRACT:
A distinctive absorbent article includes a backsheet layer and an absorbent body superposed in adjacent, facing relation with the backsheet layer. An actuating member connects to the article in liquid communication with the absorbent body and is composed of a liquid-contractible material. The liquid-contractible material is capable of shrinking upon contact with an aqueous liquid while maintaining a substantially unitary configuration. An indicating mechanism is connected to the actuating member for designating a wetness condition of the absorbent body, and is translatable along a selected path in response to the shrinkage of the actuating member.
