Abstract

This invention relates to a sanitary product for use by women for the absorption of menstrual fluid and such like. The product comprises a plug and a pad joined by a sheath. The plug is substantially cylindrical so that is fits comfortably in a vaginal cavity. The pad remains outside the vaginal cavity, but has an absorbent layer on an inward side proximal to the plug and a liquid impermeable layer on an outward side. In use, a wearer can insert a finger into the sheath from the outward side of the pad assist with insertion of the plug into the vaginal cavity. A string is provided that extends inside the sheath from the outward end of the plug to aid removal of the product. A line of weakness extends along the major axis of the pad, about which the pad is disposed to fold in use. This encourages the pad to fold around the plug to accommodate the plug during removal of the product, thus improving hygiene.
