  • Patent number: 8388593
    Abstract: A fluid-management article, such as a sanitary napkin, comprises a body-faceable, liquid-pervious cover having a top surface, a garment-faceable, liquid-impervious barrier, and an absorbent system intermediate the cover and the barrier. The fluid-management article comprises a plurality of fluid-guiding channels that surround a plurality of isolated protrusions. The channels and the protrusions are formed through the top surface of the cover of the fluid management article. The protrusions have an apex that extends a height greater than about 0.5 millimeters (mm) above at least a portion of the plurality of channels. The protrusions have a number density greater than about 0.15 protrusions/cm2.

  • Publication number: 20090324713
    Abstract: The invention is directed to a spray-on, non-woven fabric system and multilayer wound coverings for promoting wound healing, where the fabric system includes a first spray-on composition including a non-volatile carrier for keeping the wound moist and a second spray-on composition for covering the first composition and protecting the wound which includes fibers, a volatile carrier, and a binding agent, and where the multilayer wound covering includes a first layer formed from the first spray-on composition and a second layer covering the first layer, the second layer formed from the second spray-on composition.

  • Publication number: 20090324664
    Abstract: The invention is directed to a spray-on, multilayer, non-woven fabric system and multilayer topical coverings suitable for reducing or alleviating a discomforting condition of the skin and/or an area underlying the skin when applied thereto, where the fabric system includes a first spray-on composition containing a material suitable for reducing or alleviating a discomforting condition of the skin and/or an area underlying the skin when applied thereto, and a second spray-on composition, different from the first spray-on composition for covering the first composition, which includes fibers, a volatile carrier, and a binding agent, and where the multilayer topical covering includes a first layer formed from the first spray-on composition and a second layer covering the first layer, the second layer formed from the second spray-on composition.

  • Publication number: 20040267224
    Abstract: A sanitary napkin having a main body, the main body comprising a fluid-permeable cover layer, a liquid-impervious barrier layer and an absorbent system intermediate the cover layer and the barrier layer. The main body comprises a front portion, a rear portion and a center portion intermediate the front portion and the rear portion. The front portion extends laterally to at least one outermost front distal point and the rear portion extends laterally outward to at least one outermost rear distal point. A side flap projects laterally outward from the absorbent system and laterally outward from a proximal edge and is adapted to be folded over a crotch portion a user's undergarment. The side flap extends laterally outward from the proximal edge to a distal end. The distal end is not substantially laterally outward from the at least one outermost front distal point. Also, the distal end is not substantially laterally outward from the at least one outermost rear distal point.

  • Patent number: 6673418
    Abstract: An absorbent article having a body-facing cover layer, a garment facing barrier layer and an absorbent element between the cover layer and the barrier layer. The cover layer is a non-woven fabric formed from an interconnected network thermoplastic polymer fiber elements. At least a portion of the non-woven fabric is three-dimensional having a plurality of raised regions, semi-raised regions and compressed regions, the raised regions having a lower fiber density relative to the semi-raised regions, the semi-raised regions having a lower fiber density relative to the compressed regions.

  • Patent number: 5628739
    Abstract: Prebent, anatomically shaped, self-aligning absorbent products comprising a fluid permeable body facing cover, an absorbent element, a central, partially longitudinally disposed core, and a flexible, moisture barrier having partially longitudinally disposed permanent creases proximate to the longitudinal edges of the moisture barrier, are provided. Such products generally have a convex shape in the approximate center portion of the body facing surface which shape allows the product to conform to the body and more closely approximate the source of fluid discharge thereby reducing unwanted movement or misalignment which may result in leakage. Such products further generally have an hourglass shape which complements the general contour of the inside surfaces of the thighs.

  • Patent number: 5540872
    Abstract: A method of manufacturing a three-dimensional fabric of the type which may be used in absorbent garments, dressings or the like involves the use of an apertured collector element which has a predetermined three-dimensional shape. The method involves positioning material adjacent to one side of the apertured collector element and developing a pressure differential between the one side of the apertured collector element and a second, opposite side to force the fabric material against the apertured collector element. The material, which has conformed to the shape of the collector element, is then solidified into its intended three-dimensional shape.

  • Patent number: 5453296
    Abstract: A method of making an absorbent product in which pressure sensitive adhesive is used to attach the product to a user's undergarment. The product does not require release paper to protect the adhesive from unintended contact prior to use. The product is made by forming depressions in a fluid impervious barrier so as to create raised areas in the barrier that protect the adhesive. The depressions may be formed in the garment facing surface of the barrier and the adhesive applied within the depressions so that the raised areas adjacent the depressions protect the adhesive. Alternatively, the depressions may be formed in the surface of the barrier opposite the garment facing surface so as to create raised areas in the garment facing surface and the adhesive applied adjacent the raised areas.
