Absorbent Article Having A Bellows For Circulating Fresh Air

September 17, 2002

Patented is an absorbent article having opposing longitudinal edges, a first end edge and second end edge, which is opposite the first end edge. The article comprises a first waist region adjacent to the first end edge and a second waist region adjacent to the second end edge. The crotch region is disposed between the first and second waist regions. The article features a topsheet joined coextensively to the backsheet surrounding an absorbent core. A bellows is disposed on the absorbent article and is deformable to force airflow through the article. The bellows expands and contracts utilizing biomechanical motion of the wearer drawing air into the bellows through one inlet port and expelling air out from an outlet port. An inflatable air accumulator is attached to the outlet port and contains apertures disposed on the body facing side. The air accumulator provides a reservoir supplying a gradual and continuous airflow through the apertures.
