ABSTRACT:
A tampon designed for catamenial or medical use which includes a collapsible and invertible shroud (13) affixed to the front or inserted end (17) of the main tampon body (12). The shroud has an inner layer (15), adjacent to the main tampon body, fabricated from a smoothly gliding, yet permeable material which allows the main tampon body to slide from the shroud upon withdrawal. The shroud is also configured to invert behind the main tampon body during withdrawal. The collapsed and inverted shroud is significantly smaller than the main tampon body and barely contacts the surrounding body tissue, thereby eliminating withdrawal irritation.
