ABSTRACT:
A tampon which is expansible in the vagina, once inserted, for improved absorbence of menstrual fluid, particularly in post-partum women. The tampon includes an absorbent member and a core embedded within the absorbent member and constructed to expand the absorbent member so that it closely conforms to the shape of the vaginal wall. Initially, the absorbent member and core are compressed and snugly positioned within a tubular applicator which is used to guide the insertion of the tampon into the vagina. In the compressed position, the lateral extent of the leading end of the absorbent member, the end thereof to be positioned adjacent the cervix, is approximately the same as the lateral extent of the opposite end of the absorbent member. Once the tampon is discharged from the applicator, the core expands the absorbent member from the compressed position to a relaxed position where the end of the absorbent member nearest the cervix is wider than the end of the absorbent member facing the exterior of the vagina.
