Abstract
The present invention relates to a tampon having an absorbent structure and a multilayered cover substantially enclosing the absorbent structure. The cover has an outer layer capable of retaining liquid and an inner layer disposed between the outer layer and the absorbent structure. The inner layer creates a controlled interruption of fluid flow between the outer layer and the absorbent structure. This interruption allows the outer layer retains sufficient liquid to minimize vaginal wall drying prior to saturation of the absorbent structure.
