<p>Surface material (2) for covering one surface of an absorbent member (3) of an absorbent article (1) comprises a sheet of fluid impermeable material with a plurality of portions (4), each defining a fluid permeating or transfer passage (8). The surface material comprises a plurality of top portions (5), each having a convex curved surface defining an empty internal space (9) which, in use, contact the body of the user, a plurality of open bottom portions (6) and a plurality of annular wall portions (7). Each hole portion (4) comprises a plurality of adjacent top portions defining an opening (5a), a single open bottom portion (6) and a single annular wall portion (7) connecting the said top portions (5) and the said open bottom portion (6). The open bottom portion (6) has an opening (6b) at its lower end. Each permeating passage (8) has a smallest portion (5b) of minimum cross-sectional area situated between the mouth (5e) of the opening formed by the associated top portions (5) and the open bottom portion (6), the cross-sectional area of the permeating passage increasing from the smallest portion towards the mouth of the opening defined by the top portions and remaining substantially constant or increasing towards the open bottom portion. <IMAGE></p> |
