Abstract
Abstract A medicated tampon is disclosed for contraception, hygienic, or like uses, including in a swab or douche applicator, along with a novel method of fabricating the medicated tampon. The tampon is made by providing a first sheet of absorbent material to form the corpus of the tampon, and overlaying the first sheet with a second overwrap sheet of non-woven material which is permeable by body fluids. In one form of the invention a medicament is deposited between the overwrap and corpus sheets. In another form of the invention, the overwrap sheet is impregnated with a medicament. The superimposed sheets then are rolled and formed into the desired shape of the tampon with the overwrap sheet on the outside thereof so that the medicament is disposed nearest the outside of the tampon when inserted into a vaginal or other anatomical cavity.
