  • Patent number: 5507735
    Abstract: A sanitary napkin assembly is disclosed having a second absorbent pad that is superposed over and movably secured to a first absorbent pad. Each absorbent pad has a centrally positioned, longitudinal axis. The securement device securing the second absorbent pad to the first absorbent pad allows the second absorbent pad to move along one of the longitudinal axes and preferably permits the second absorbent pad to rotate through an angle of about 90 degrees.

  • Patent number: 4973325
    Abstract: An absorbent article is disclosed having a pair of absorbents positioned adjacent to each other. Each absorbent has a first surface facing the body of a user and a second surface aligned opposite to the first surface. A fluid-impermeable baffle is positioned adjacent to the second surface of each absorbent and extends upward around a portion of the absorbents. A fluid permeable cover is positioned adjacent to the first surface of each absorbent and can be sealed to the baffle. The absorbent article further includes a transfer member for facilitating movement of body fluids from the cover downward and outward to distant areas of the absorbents. The transfer member is positioned above, between and below at least a portion of the absorbents and is coaxially aligned the the longitudinal central axis of the article. The transfer member is also spaced apart from the periphery of the absorbents.

  • Patent number: 4846824
    Abstract: A labial pad (30) having an anatomically conformable configuration with a generally ovate geometry defined by a principal longitudinal axis (L), a minor transverse axis (T) and a generally orthogonal lateral or height axis (H), is comprised of a laterally upwardly directed projection (52) lying generally along the longitudinal axis within the posterior region (54) of the pad and having a prominence (64) proximate the distal end (60) thereof tapering toward the proximal end (58) along the longitudinal axis and to the opposed sides (62) along the transverse axis, wherein the projection is configured for disposition within the vestibule (32) of a wearer over a region bounded generally by the posterior labial commissure (36) and the labia terminating at or about the latter and extending forwardly therefrom over the vulva, to occlude the vestibule against flow of menses or the like while protecting the urogenitals from chafing contact.

  • Patent number: 4804380
    Abstract: The invention is generally accomplished by forming a three-dimensionally shaped, externally worn feminine protection device which has been mechanically shaped by folding, molding or other forming techniques in such a way that it has a raised portion located within the back one-half to two-thirds of the device that functions to cause the pad to readily fit to and generally align itself within the inverted V-shaped regions of the woman's lower abdominal region, vulva, perineum and the anterior portion between the buttocks. The forward portion of the device of the invention generally is flattened in use to cover externally the area of the pubic mons and the area exterior of the clitoris. The back portion of the device is formed in a peak like shape which readily adjusts to and molds to the inverted V-shape of the rear portion of the labia, the perineum and the forward portion of the area between the buttocks.

  • Patent number: 4743245
    Abstract: A labial pad (30) having an anatomically conformable configuration with a generally ovate geometry defined by a principal longitudinal axis (L), a minor transverse axis (T) and a generally orthogonal lateral or height axis (H), is comprised of a laterally upwardly directed projection (52) lying generally along the longitudinal axis within the posterior region (54) of the pad and having a prominence (64) proximate the distal end (60) thereof tapering toward the proximal end (58) along the longitudinal axis and to the opposed sides (62) along the transverse axis, wherein the projection is configured for disposition within the vestibule (32) of a wearer over a region bounded generally by the posterior labial commissure (36) and the labia terminating at or about the latter and extending forwardly therefrom over the vulva, to occlude the vestibule against flow of menses or the like while protecting the urogenitals from chafing contact.

  • Patent number: 4673403
    Abstract: The invention is generally accomplished by providing an incontinent garment or feminine pad having an indicator thereon to aid in proper placement of the pad onto the body of the wearer.The invention in preferred form provides a sanitary napkin configured for partial labial disposition within the vestibule of the wearer, and for at least partially occluding said vestibule respecting fluid flow therefrom, said napkin comprises a fluid-absorbent body having a posterior region including a raised profile for projection within the vestibule intermediate the labia majora inwardly bounding the same from a position posteriorly remote from the clitoris and extending to the rearwardmost aspect of said vestibule, and anterior region merging with said posterior region and for generally external disposition about the vulvar region over said labia majora and spaced from said clitoris with a visual and/or tactile indicator located in the area of the pad that is to be placed immediately below the vestibule of the wearer.
