    Abstract: A sanitary napkin for retention of vulvar discharge includes a shell that defines an interior space. The shell is flexible and liquid impermeable. A ridge, which defines a canal, extends from the front of the shell around a perimeter of an opening. An absorbent is positioned in the interior space and the canal. A pair of fasteners is coupled singly to and extends from opposing edges of the shell. A first improvement is the liquid impermeability of the front of the shell, wherein vulvar discharge is effectively retained within the interior space of the shell. A second improvement is the ridge that is positioned on the front. The shell is sealably positionable over the vulva of the user such that vulvar discharge is directed to the opening.

  • Patent number: 10213347
    Abstract: An absorbent article (100-1200) is capable of providing comfort to the wearer and can maintain dryness and inhibit the leakage of fluid. The absorbent article (100-1200) includes a multi-layered topsheet (138). The multi-layered topsheet (138) includes a first topsheet layer (106) having an opening (148) and a second topsheet layer (108) disposed under the first topsheet layer (106). The first topsheet layer (106) and the second topsheet layer (108) are joined together by a seal that, in one embodiment, generally corresponds with the shape of the opening (148). Further, a first sub-topsheet layer (116) is situated beneath the multi-layered topsheet (138) and has an opening (150) that is smaller than the first topsheet layer opening (148). This combination of openings (148, 150) situated one below the other provides for an absorbent article (100-1200) that can maintain a high level of dryness and its ability to conform to the wearer's body, and inhibit the leakage of bodily fluids due to a funnel-like effect.

  • Patent number: 9889052
    Abstract: An absorbent article has a lower absorbing core and an upper absorbing core. Each absorbing core includes a liquid-holding material and a liquid-permeable core-wrapping sheet. The liquid-holding material is covered by the liquid-permeable core-wrapping sheet, but it also has an exposed portion not covered by the liquid-permeable core-wrapping sheet. The exposed portions of the lower absorbing core and the upper absorbing core face each other and the liquid-holding materials are connected with each other at the exposed portion. Because the liquid-holding material of the upper absorbing core is in direct contact with the liquid-holding material of the lower absorbing core, the area provides a path through which liquid flows smoothly from the upper absorbing core to the lower absorbing core. Also, because the upper and lower liquid-holding materials are covered by the core-wrapping sheets, deformation of the liquid-holding materials is prevented.

  • Patent number: 9849602
    Abstract: A method for making an extrusion coated perforated nonwoven web. The method comprises the steps of extruding a molten polyethylene coating onto a nonwoven web, and aperturing the molten polyethylene coating through heat and pneumatic pressure differential to create microperforations therein at a density of between about 35 and about 120 perforations per linear inch. The resulting microperforated nonwoven web is then thermomechanically perforated by feeding it through perforating rolls, at least one of which has raised protuberances to create macroperforations that extend though at least the polyethylene coating. The macroperforations have a density of between about 6 and about 35 perforations per linear inch. The perforated nonwoven web is useful as a topsheet for absorbent articles.

    Abstract: A lightweight component is equipped with two cover layers, which are made of a wood material, and a filling disposed in between the layers after cutting everything to size, having an edge support including thermoplastic material. The edge support is anchored in both the first and second cover layers starting from the narrow side. Anchoring is achieved by bringing the edge support into contact with the respective cover layer and coupling mechanical vibrations into the edge support by a sonotrode engaging from the narrow side. The edge support at the same time is pressed against the cover layer such that, in the region of a transition between the thermoplastic material and the wood material of the cover layer, part of the thermoplastic material is liquefied and pushed into the cover layer material, thereby producing a positively engaged anchoring after hardening.

  • Patent number: 8827974
    Abstract: The present invention provides an absorbent tampon having a mass of an absorbent composite compressed into a generally cylindrical shape. The absorbent composite used in the tampon of the present invention has at least a first layer and a second layer wherein the second layer is adjacent the first layer. The first layer is prepared from a first absorbent material having a first physical property and the second layer is prepared from a second absorbent material having a second physical property, wherein the first physical property is the same physical property as the second physical property, but the value of the second physical property is different from the first physical property. By providing layers in the absorbent composite different physical properties, the tampons of the present invention can have different properties at various locations of the tampon to provide a tampon having desirable features, such as improve leakage protection.

  • Publication number: 20140148774
    Abstract: Aspects of the methods and apparatuses herein involve applying fluids onto an advancing substrate. The apparatuses and methods herein may provide for the application of viscous fluids, such as adhesives, in pre-determined patterns to an advancing substrate. The fluid application apparatus may include a slot die applicator and a substrate carrier. The slot die applicator may include a slot opening, a first lip, and a second lip, the slot opening located between the first lip and the second lip. And the substrate carrier may be adapted to advance the substrate past the slot die applicator as the slot die applicator discharges adhesive onto the substrate. In operation, when a first surface of the substrate is disposed on the substrate carrier, the substrate carrier advances a second surface of the substrate past the slot opening of the slot die applicator.

  • Publication number: 20140142527
    Abstract: A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from a multi-layered, elastic film laminated to a nonwoven web facing. Latent elasticity is imparted to the composite through the use of at least one base layer that contains a thermoplastic elastomer and at least one skin layer that contains a propylene/?-olefin copolymer. During formation, the film is stretched in one or more directions to orient the elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the chains may be held in place by the relatively stiff semi-crystalline domains of the propylene/?-olefin copolymer. The stretched elastic film may subsequently be relaxed and bonded to a nonwoven web facing to form the composite. The composite may be later activated (e.g., heated at or above the softening point of the copolymer) to soften the crystalline domains and allow the chains to return to their unoriented state.
