Abstract
Abstract An absorbent pad such as a sanitary napkin having a self-contained disposal means is provided. The napkin is worn in the conventional manner. After use, the self-contained disposal means is folded over the soiled portion of the napkin. The folding over can be accomplished without user contact of the soiled area of the napkin, making the disposal process much less objectionable. Also, as the disposal means completely encloses the soiled napkin, disposal of the napkin can be effected in a sanitary fashion, thus theoretically decreasing the likelihood of transmission of infectious disease.
