  • Patent number: 7781640
    Abstract: A disposable absorbent article including a wetness sensation member and visible highlighting indicating the presence of the wetness sensation member to facilitate an opportunity for the toilet training of the wearer. The wetness sensation member includes a permeable layer and a flow control layer. Urine deposited on the wetness sensation member can penetrate through the permeable body-facing layer in a z direction away from the wearer to the flow control layer. The flow control layer retards the passage of the urine through the wetness sensation member in the z direction while supporting the movement of the urine in an x-y plane to increase the wetted area contacting the wearer's skin and thereby enhance the wearer's awareness that urination has occurred. The visible highlighting is visible when viewing a body-facing surface of the article and may be associatively correlated with an externally visible marking and/or with the concept of toilet training.

  • Patent number: 7767875
    Abstract: A toilet training wetness indicator for alerting a wearer to urination and a garment incorporating such an element. The toilet training wetness indicator, which may be an insertable wetness indicator or integrated directly into a garment, such as training pants, comprises a liquid permeable enclosure having a liquid absorbent body enclosed therein. The liquid absorbent body absorbs liquid within the pants and applies hydraulic pressure to the enclosure upon absorption of a preselected amount of liquid. The enclosure limits expansion of the absorbent body so that the wetness indicator stiffens as liquid is absorbed. The wetness indicator has a first stiffness and is relatively pliable when dry and a second stiffness greater than the first stiffness upon absorption of the preselected amount of liquid.

  • Publication number: 20100100065
    Abstract: An absorbent element for the absorption of body fluids in sanitary articles comprises a first layer of sheet material presenting an array of hollowed formations (16) with respective mouth parts, as well as masses (18) of superabsorbent material that is able to expand as a result of the absorption of body fluid, which are set in the aforesaid hollowed formations (16). A second layer of sheet material (12) is applied on the first layer of sheet material (10) so as to cover the mouth parts of the hollowed formations (16). At least one of the layers of sheet material (10, 12) is permeable to body fluids to enable the body fluids themselves to penetrate into the hollowed formations and be absorbed by the masses of superabsorbent material (18) that expand in the hollowed formations (16), creating a first level of absorption of body fluids.

  • Patent number: 7696401
    Abstract: An absorbent material formed at least in part of a cross-linked polymer. The absorbent material has a centrifuge retention capacity as determined by a Centrifuge Retention Capacity Test of at least about 20 g/g and a gel bed permeability under load as determined by a Gel Bed Permeability Under Load Test of at least about 300×10?9 cm2 or a free swell gel bed permeability as determined by a Free Swell Gel Bed Permeability Test of at least about 2,500×10?9 cm2. The cross-linked polymer may comprise either at least about 75 weight percent anionic polymer or at least about 75 weight percent cationic polymer. In one embodiment, the cross-linked polymer is surface treated with a water soluble non-cross-linked polymer having a potential for becoming charged opposite that of the cross-linked polymer.

  • Patent number: 7678095
    Abstract: The present invention provides a pre-expanded tampon pledget formed from cellulosic absorbent fibers. The fibers are not tightly compressed, thus, the pledget has a reduced fiber density. As a result, a softer, more pliable pledget is formed that not only increases user comfort during use, but also affords a user with comparable and/or increased leakage protection over conventional tampons or tampon pledgets.
