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.
Claims17
A tampon comprising an absorbent structure and a multilayered cover substantially enclosing the absorbent structure, the cover comprising an outer layer capable of retaining liquid and an inner layer disposed between the outer layer and the absorbent structure;
- wherein the inner layer creates a controlled interruption of fluid flow between the outer layer and the absorbent structure whereby the outer layer retains sufficient liquid to minimize vaginal wall drying prior to saturation of the absorbent structure.
A tampon comprising an absorbent structure and a multilayered cover substantially enclosing the absorbent structure, the cover comprising an outer layer capable of retaining liquid and an inner layer disposed between the outer layer and the absorbent structure;
- wherein the inner layer creates a spacer to disrupt fluid flow between the outer layer and the absorbent structure in conditions of low fluid availability whereby the outer layer retains sufficient liquid to minimize vaginal wall drying prior to saturation of the absorbent structure.
A tampon comprising an absorbent structure and a multilayered cover substantially enclosing the absorbent structure, the cover comprising (a) a fibrous outer layer having a first average pore size and being capable of retaining liquid and (b) a fibrous inner layer having a second average pore size and disposed between the outer layer and the absorbent structure;
- wherein second average pore size is greater than the first average pore size and the inner layer creates a controlled interruption of fluid flow between the outer layer and the absorbent structure whereby the outer layer retains sufficient liquid to minimize vaginal wall drying prior to saturation of the absorbent structure.
