  • Publication number: 20120165769
    Abstract: The present invention relates to a sanitary napkin whose securing means includes a braid of absorbent material. The braid structure maximizes absorbency, while minimizing bulk and thus allows the pad to be comfortably held in place during use, in much the same way that the popular thong underwear are held.

  • Publication number: 20120165775
    Abstract: An absorbent composite material may be manufactured by applying a flexible absorbent binder polymer (FAB), also referred to herein as a flexible superabsorbent, during the creping step of conventional tissue manufacturing. As such, the costly process of applying FAB to a substrate by spraying or printing followed by drying may be eliminated. The creping step has the additional advantage of improving the flexibility and softness of the FAB treated fibrous web.

    Abstract: A reusable diaper includes forward and rearward waist portions. At least one corner tab may be releasably attachable to the forward and rearward waist portions. The diaper may include at least one pocket configured to receive therein at least a portion of the corner tab. The pocket may be substantially impervious to liquids, such that positioning of the portion of the corner tab in the pocket helps inhibit wicking of liquid through the pocket and into the corner tab. Some embodiments may include first and second sets of interchangeable corner tabs that are releasably attachable to the forward and rearward waist portions. The second set of corner tabs may be sized differently than the first set of corner tabs such that the diaper size is adjustable depending on whether the first or second set of corner tabs are used.

  • Publication number: 20110319850
    Abstract: Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants and the like, having elastomeric ear panels and a fastening system that provides the user with different options as to how the absorbent article may be fitted to and removed from the wearer. The absorbent articles allow the wearer to choose between conventional and pull-on diaper configurations, or combinations thereof, and properly and comfortably fit a large range of wearer sizes. Further, the absorbent articles can be pulled on and/or off as a pant. This feature is provided by the ear panels which maintain sufficient tension to hold the diaper on the wearer throughout the period of use without harming the wearer's skin, while providing enough stretch to allow the diaper to be pulled up or down over the wearer's hips. The fastening system is refastenable for convenience yet strong enough to maintain the diaper in a fastened configuration without becoming detached if the diaper is pulled on or off the wearer.
