- 9. An article according to claim 1 wherein the absorbent material on at least the side of the tubular body remote from the inner casing sheet comprises a body of highly-absorbent material having an hour-glass configuration which lies nearest the outer casing sheet, and two side-bodies of rapidly-absorbing material located on opposite lateral sides of the tubular body.
- 10. An article according to claim 1, including two liquid barriers bordering on respective opposite lateral sides of the tubular body.
- 11. An article according to claim 10, wherein the liquid barriers are comprised of strips of liquid-impervious plastic material.
- 12. An article according to claim 9, including two liquid barriers bordering on respective opposite lateral sides of the tubular body, and each liquid barrier separating one of the side-bodies from the tubular body.
