Abstract
An absorbent article for absorption of bodily fluids is provided, including a layer of non-absorbent material defining a tunnel shaped loop and a central portion enclosed by the loop, and an absorbent material retained within the tunnel-shaped loop. The non-absorbent material includes a plurality of apertures through which fluid can flow to reach the absorbent material, and an overwrap material overlies the non-absorbent material to transport fluid over the surface of the non-absorbent material. Preferably the absorbent article is a tampon and the loop is ring shaped.
