  • Patent number: 8475425
    Abstract: A catamenial tampon comprises a compressed absorbent member having an inner region and an exterior surface, the compressed absorbent member comprising an absorbent material. An overwrap substantially covers the exterior surface of the compressed absorbent member. The overwrap comprises an apertured fluid pervious material that is hydrophobic or rendered hydrophobic relative to the compressed absorbent member. The fluid pervious overwrap therefore tends to remain free of fluid as the fluid is preferentially partitioned into the absorbent member.
