ABSTRACT:
A catamenial device such as a tampon which comprises a segment of a rapidly reexpandable hydrophilic polymeric foam held in compression to less than 50 percent of its original dry volume and a constraining means holding said segment in compression which is adapted to provide lubrication for insertion of said segment into an animal's body cavity and to thereafter rapidly disintegrate, wherein said constraining means comprises a capsule possessing a plurality of perforations distributed about its surface to hasten disintegration. The devices of the present invention may be stored over an extended period of time without the difficulty of premature escape of the segment from the capsule.
