  • Patent number: 5580423
    Abstract: The present invention provides a wet pressed paper web. The web has a first relatively high density region having a first thickness K, a second relatively low density region having a second thickness P, which is a local maxima, and a third region extending intermediate the first and second regions. The third region includes a transition region having a third thickness T, which is a local minima. The present invention also provides a method of making a wet pressed web. An embryonic web of papermaking fibers is formed on a foraminous forming member, and transferred to an imprinting member to deflect a portion of the papermaking fibers in the embryonic web into deflection conduits in the imprinting member. The web and the imprinting member are then pressed between first and second dewatering felts in a compression nip to further deflect the papermaking fibers into the deflection conduits in the imprinting member and to remove water from both sides of the web.

  • Patent number: 5520778
    Abstract: Disclosed is a cellulosic fibrous structure, particularly a consumer product such as toilet tissue, facial tissue or a paper towel. In a first embodiment, extending outwardly from each face of the cellulosic fibrous structure is a plurality of protuberances. The protuberances extend bilaterally outwardly from the plane of the cellulosic fibrous structure in both directions. The bilaterally extending protuberances increase the caliper and texture of the consumer product embodied in the cellulosic fibrous structure. In a second embodiment, the protuberances extend outwardly, and are induced by fluid embossing, rather than mechanical embossing. Also disclosed is a fluid embossing process for making such cellulosic fibrous structures.

  • Patent number: 5520674
    Abstract: An absorbent article having an expandable component. The expandable component comprises a compressed, resilient element disposed within an air impermeable envelope. The compressed element provides the absorbent article with a thin, low bulk profile prior to use of the disposable absorbent article, thereby reducing shipping and storage space. At the point of use of the absorbent article, the air impervious envelope is opened, thereby permitting entry of air into the envelope and expansion of the compressed element. In one embodiment the expandable component is a spacer for maintaining fecal void space in a disposable diaper. Alternatively, the expandable component can provide displacement of the topsheet relative to the backsheet along the longitudinal centerline of a sanitary napkin.

  • Patent number: 5462166
    Abstract: The present invention provides a sanitary napkin enclosed within a flexible wrapper formed of thermoplastic film. The sanitary napkin and wrapper are folded as a unit about at least two lateral fold axes, so that the sanitary napkin is disposed between two or more layers of the wrapper. The layers of the folded wrapper are joined by a pair of laterally spaced apart releasable seals. Each releasable seal extends longitudinally along a longitudinal edge of the wrapper. Each releasable seal comprises an array of discrete thermal-mechanical bonds joining the layers of the wrapper. The array of discrete bonds extends in a first direction generally parallel to a package edge and in a second direction generally perpendicular to the package edge. This arrangement of ratios of bond width to bond spacing reduces the strength of the seal parallel to the package edge relative to the strength of the seal perpendicular to the package edge.
