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.
Claims9
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.
A method of manufacturing an absorbent article comprising
- (a) surrounding an absorbent material with a resilient, impermeable covering so that the covering defines a tunnel-shaped loop and the absorbent material is sealed within the tunnel, and
- (b) providing a web spanning the loop defined by the covering.
