1. A method of manufacturing an absorbent article comprising:
- (a) forming a first channel in a first portion of a formable material, said channel being constructed to define a closed loop, (b) providing a plurality of apertures in said formable material, in fluid communication with said channel, (c) placing an absorbent material in said channel, (d) forming a second channel, having dimensions substantially identical to those of said first channel, in a second portion of formable material, (e) aligning said first and second portions of formed material so that the corresponding channels in said first and second portions define a closed tunnel, (f) sealing said first and second portions together around the outer periphery of said closed loop, and (g) providing an overwrap material covering the outer surface of the absorbent article.

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.
