  • Patent number: 5342338
    Abstract: A disposable absorbent article, such as a diaper. The disposable absorbent article has a first topsheet with apertures large enough for low-viscosity fecal material to pass through to a secondary topsheet. The secondary topsheet immobilizes the fecal material in position for dewatering, so that the liquid components of the fecal material are absorbed by the core and the solid components of the fecal material are separated from the liquid components. This arrangement provides for easier cleaning of the wearer when the soiled disposable absorbent article is removed.

  • Patent number: 5234422
    Abstract: A unitary disposable absorbent article such as a catamenial pad or incontinent pad is provided with an elasticized side flap by operatively associating an elastic member on both the upper surface and the lower surface of the side flap. The elastic member is preferably joined to the inner surface of the side flap as well as the outer surface of the side flap by folding it about the distal edge of the side flap. In a preferred embodiment, the elastic member comprises an elastomeric laminate of an elastomeric layer and a coverstock layer, with the coverstock layer being on the outside of the product, so that the sanitary napkin is provided with soft longitudinal edges which contact the wearer during use. In addition, the elastomeric laminate provides relatively low tension that while raising the side flaps of the product to be a barrier against lateral leakage, also maintain the product in a shape which does not encourage fluid run-off or leakage at the ends of the pad as well as providing a bunching benefit.

  • Patent number: 5085654
    Abstract: Disposable diapers provided with breathable leg cuffs. Disposable diapers comprise a topsheet, an absorbent element, and a backsheet. The leg cut of a disposable diaper is that part of the diaper which fits about the wearer's leg. Extensions of the backsheet can be used to form cuffs which are frequently elasticized. In the present invention the cuffs are formed of a material which allows passage of vapor ("breathes") while tending to retard the passage of liquid. Apertured thermoplastic films are examples of such materials. Certain advantages accrue in cuffs which are permeable to vapor in their distal portions and impermeable in the portions adjacent the absorbent element. If the disposable diaper has a breathable backsheet, the cuffs are constructed to be more permeable to vapor per unit area in their breathable portions than is the backsheet.
