  • Patent number: 4675013
    Abstract: A sanitary napkin is provided which obviates the problem of stain propagating across the body facing side of the napkin while still facilitates manufacturing processes. Specifically, the napkin comprises a pad having a wrapper which overlies the garment facing side of the pad, the longitudinal sides of the pad, and peripheral portions of the body facing surface of the pad. The wrapper comprises a body fluid impervious sheet laminated to a fibrous sheet with the fibrous sheet being wider than the impervious sheet. The fibrous sheet has a width sufficient to overlie the garment facing surface, the longitudinal sides and the longitudinal peripheral portions of the body facing side of said pad, but is insufficient in width to overlie the central major portion of the body facing surface of the pad.
