Abstract
Abstract A sanitary napkin is provided in elongate sheet form such that the fluid impervious baffle, the absorbent, and the fluid impervious cover are coterminous at the longitudinal edges and the napkin stock itself extends at least about four times the length of a conventional mini pad. This sheet stock can be shaped by the ultimate user not only longitudinally to provide the precise length, but also in any configuration desired. In another form the invention contemplates this napkin sheet stock in roll form packaged in a dispenser which preferentially has means for longitudinal cutting.
